This paper aims to study the problems of surplus interaction, poor real-time performance, and excessive processing of information in the micro-grid scheduling and decision-making process. Firstly, the micro-grid dual-loop mobile topology structure is designed by using the method of block-chain and multi-agent fusion, realizing the real-time update of the decision-making body. Secondly, on the basis of optimizing the decision-making body, a two-layer model of intelligent decision-making under the decentralized mechanism is established. Aiming at the upper model, based on the theory of block-chain consensus mechanism, this paper proposes an improved evolutionary game algorithm. The maximum risk-benefit in the decision-making process is the objective function, which realizes the evaluation and optimization of decision tasks. For the lower layer model, based on the block-chain distributed ledger theory, this paper proposes an improved hybrid game reinforcement learning algorithm, with the maximum controllable load participation as the objective function, and realizes the optimal configuration of distributed energy in the micro-grid. This paper reveals the rules of group intelligent decision making in micro-grid under multi-task. Finally, the effectiveness of the proposed algorithm is verified by using Beijing Jin-feng Energy Internet Park data.


How to find the cable fault point quickly and accurately and restore the power supply as soon as possible has become a difficult problem for power supply enterprises. Therefore, a fault detection method based on SSTDR is designed in this paper. The principle of SSTDR technology is analyzed. Based on the distance measurement of signal, the PN code is modulated by cosine signal, which makes the test signal have the white noise characteristic of mean value 0, and has stronger anti-interference ability. It can detect the fault point of low-voltage cable under the condition of low SNR. In the simulation experiment, the fault problems of the low-voltage cable in open and short circuit are detected respectively, which verifies the effectiveness of the SSTDR technology and makes a contribution to the safe use of the low-voltage cable(Abstract).


This paper describes the evolution of the Polish developer sector starting from the socialistic times up to the recent years. The communist era left the construction sector of the new Republic of Poland a legacy of housing cooperative as an organization responsible for building dwellings, large panel as the dominant technology of their construction, housing estate planning adjusted to the system of construction crane rails, cities and towns with centers inhabited by lumpenproletariat and a mentality of Poles, used to the thought that a typical way of coming into possession of a dwelling was to "get, arrange to get or inherit" one. Contractors consisted of state-owned conglomerates, while the quality of work and the subculture of construction workers was a favorite topic of movie comedies and stand-up sketches. The second part of legacy of the People's Republic of Poland was the list of what was either nearly or completely missing: regular mortgage loans and banks ready to grant them; professionals specializing in sales of dwellings; clearly defined ownership statuses for land property, especially in Warsaw; rules of operation for firms constructing and selling dwellings, including, most importantly, rules for sales of units under construction; management


We aimed to discover the molecular mechanism of hsa_circ_0076694 (circRUNX2) on osteogenic differentiation. We also explored the interaction between circRUNX2, miR‐203 and RUNX2.


Pet coke used as fuel is taking over an increasing share of the heat consumption in the cement industry. The rise of oil price, combined with a low world market price for the pet coke itself, makes it a still more attractive fuel for the cement industry and other larger fuel consuming industries. Pet coke, being a relatively low reactive fuel, is expected to cause problems with respect to the degree and speed of the burn out process. Certain precautions have to be made to make full use of pet coke. F. L. Smidth & Co has carried out a number of mill and kiln system conversions towards the use of pet coke, proving the use of pet coke to be very feasible. In this paper it will be demonstrated, by the use of industrial case studies that pet coke is a very useful fuel for the cement industry. It will be demonstrated, how pet coke can be ground to required fineness in a ball mill as well as in a vertical roller mill. Furthermore, it will be demonstrated how different kiln types, SP-, ILC- and SLC-kilns, will operate with pet coke being the only fuel used, and how existing kiln systems are modified by implementing the unique SLC-D calciner. Finally, the main pet coke quality parameters for evaluating the possibility of using the pet coke will be explained.


Varietal development, release and quality seed production of new high yielding and disease resistant wheat varieties is a continuous effort and a pre-requisite for sustainable wheat production. NIFA-AMAN 2017 as a new improved variety was developed at Nuclear Institute for Food and Agriculture, Peshawar, Pakistan. From 4 Stem Rust Screening Nursery (4 SRSN) the genotype was selected and material received from CIMMYT in 2009-10. Based on disease tolerance and higher grain yield, the genotype (SRN-09111) was selected from the nursery sown during 200910. Similarly, in preliminary and advanced yield trials conducted at NIFA during 2010-11 and 2011-12, the genotype was evaluated. The SRN-09111 was also evaluated in microplot trial at 07 different sites of the province during 2012-13, genotype showed outstanding yield performance among the other genotypes. The genotype out yielded (5647 & 4351 kg ha) in 1 year mandatory evaluation of National Uniform Wheat Yield Trials (NUWYT) during 2013-14 and Ranked 1 at 5 sites in Khyber Pakhtunkhwa (KP) and 4 across Pakistan. On 2 year mandatory evaluation in NUWYT, conducted during 2014-15, the genotype yield ranked 2 (4047 kg ha) at 31 sites on Pakistan basis. It is early maturing, disease tolerant and high yielding variety, more suitable for different agro-climatic zones of KP. Moreover, for yellow rust, leaf rust and stem rust, Relative Resistance Index (RRI) falls under acceptable range. The Provincial Seed Council (PSC), Khyber Pakhtunkhwa approved SRN-09111as a variety in 37 meeting held on 19 September, 2017 at Peshawar.


The long range goal o f this research is to understand the role of the solvent in condensed phase reactions. In the gas phase, great strides have been made towards understanding chemical reactivity at the level o f individual quantum states. Liquid state reactions are not as well understood due to complicated many-body interactions with the solvent. Our approach has been to study simple reactions in solvents near their critical state. Here a small change in pressure, at constant temperature, allows a continuous change in solvent bulk density and viscosity, from near-liquid to gas-like properties. In this way reactions can be studied across the interface between gas phase behavior and the poorly understood liquid state. In addition to chemical reactivity, the research directly investigated solvent structure and dynamics in the supercritical state. The unique solvent properties o f supercritical fluids (SCFs) are the basis for SCF extractions and chromatography. Microscopic details o f the fluid structure and dynamics have a direct bearing on the solubility and reaction behavior o f these fluids. The high-intensity o f the generated ultrafast pulses (0.01 to 60 GW/cm2) necessitated the need to investigate the phenomenon o f nonlinear absorption. Initial studies were perform ed on one-dimensional polydiacetylene polym er films. Mechanisms involving two-photon absorption were developed for explanation the new finding. The available high power in the femtosecond experimental system allowed investigation o f solvent molecular relaxation processes. Using the Optical Kerr Gate


The acoustic pressure generated by cavitation inception in a tip vortex flow was simulated in water containing a realistic bubble nuclei size distribution using a surface-averaged pressure (SAP) spherical bubble dynamics model. The flow field was obtained by the Reynolds-averaged Navier-Stokes computations for three geometrically similar scales of a finite-span elliptic hydrofoil. An acoustic criterion, which defines cavitation inception as the flow condition at which the number of acoustical peaks above a pre-selected pressure level exceeds a reference number per unit time, was applied to the three scales. It was found that the scaling of cavitation inception depended on the reference values (pressure amplitude and number of peaks) selected. Scaling effects (i.e., deviation from the classical σ i R 0.4 e ) increase as the reference inception criteria become more stringent (lower threshold pressures and less number of peaks). Larger scales tend to detect more cavitation inception events per unit time than obtained by classical scaling because a relatively larger number of nuclei are excited by the tip vortex at the larger scale due to simultaneous increase of the nuclei capture area and of the size of the vortex core. The average nuclei size in the nuclei distribution was also found to have an important impact on cavitation inception number. Scaling effects (i.e., deviation from classical expressions) become more important as the average nuclei size decreases.


Lissencephaly is a rare genetic disorder of brain malformation. It is characterized by the absence of normal folds or convolutions of the cerebral cortex. It is caused by abnormal neuronal migration during a period of embryonic development. It has various symptoms such as difficulty in swallowing, unusual facial appearance, abnormal muscular spasms, failure to thrive, extreme psychomotor retardation, deformities of fingers, toes, or hands, intellectual disability, and the seizure episodes. There are two variants of Lissencephaly namely type I and II. This case report has highlighted a rare case of type II Lissencephaly with chronic epilepsy and behavioral disturbances in a 12-year-old child managed effectively with a mood stabilizing antiepileptic drug named Divalproex sodium and a benzodiazepine named Clobazam.


At a normative level, the significance tests appear to be ill-suited and the main criticisms are reported. At a descriptive level, both examination of statistical textbooks, re-analyses of published papers and experiments about the use of significance tests by psychologists clearly reveals many misuses. At a prescriptive level, alternative solutions are considered, especially the Bayesian methods which appear to be especially attractive.


Recent attempts to detect [O iii] 88$\, \mu$m emission from super-early (z > 10) galaxy candidates observed by JWST have been unsuccessful. Non-detections can be either due to wrong photometric redshifts or to the faintness of the line in such early systems. By using zoom-in simulations, we show that if redshifts of these galaxies are confirmed, they are faint and mostly fall below the local metal-poor $\rm [O\, {\small III}]-SFR$ relation as a result of their low ionization parameter, Uion ≲ 10−3. Such low Uion values are found in galaxies that are in an early assembly stage, and whose stars are still embedded in high-density natal clouds. However, the most luminous galaxy in our sample ($\rm {log}[L_{\rm {[O\, {\small III}]}}/\mathrm{L}_\odot ] = 8.4$, Uion ≈ 0.1) could be detected by ALMA in only 2.8 h.


Through three years' practice,a systemic observation on phonological period of "Shilifeng" was conducted to summarize seven high-yield cultivation technologies: timely seeding,fostering strong seedlings,timely transplanting,rational close planting,fertilizer and irrigation management,plant protection,timely harvesting.


A model of interbank rivalry is developed and tested in the context of a one period duopolistic game with stochastic variability in deposit and loan demand. A procedure involving two specification tests is used to examine model implications. Results confirm that banks change their lending rates not only in response to changing own cost conditions but also in recognition of mutual interdependence – strategic competition. The possibility that banks respond strategically to each other may have implications for antitrust analysis.

Dengue infections typically present with fever and thrombocytopenia. Although good number of patients improve with supportive care, few can have a fulminant course with multiorgan dysfunction. In endemic zone co-occurring illness like Sickle cell disease can contribute to poor outcome. Various splenic complications of Sickle cell disease include massive splenomegaly with sequestration, large infarcts and abscess requiring splenectomy. We report an interesting case of dengue fever, who developed shock and acute abdomen during hospital stay. Further evaluation revealed multiple splenic infarcts with correlating histopathology and etiological work up including hemoglobin electrophoresis helped in the de novo detection of the underlying sickle cell trait.International Journal of Human and Health Sciences Vol. 05 No. 04 October'21 Page: 519-524


Title of Thesis: Computerize Data Information for Architectural Design Syau-yi Yu, Master of Science in Architecture, 1989 Thesis directed by: Dr. David L. Hawk, Professor of Architecture Computer-aided architectural design is technically and commercially feasible yet experience in the architectural profession to date is paradoxical. Many who apply computers to architecture appear satisfied but the tangible benefits are seldom obvious and even where computers are used in firms it is not done to the fullest potential.


Hydroxylations of 2-(1-hydroxyalkyl)-1,4,5,8(or 1,4,5,6,8)-tetra(or penta)methoxynaphthalenes and 2-(1-hydroxyalkyl)-1,4-dimethoxybenzenes at the 3-position were accomplished by a one-pot procedure. The same procedure has been found to be applicable to 2-(1-hydroxyalkyl)naphthalenes and (1-hydroxyalkyl)benzenes having no methoxyl substituent.

prepared for: 8 th International European Forum on System Dynamics and Innovation in Food Networks February 17 21, 2014 Innsbruck-Igls, Austria Analysis of the innovation journey and the role of interactions in networks in the agricultural sector Evelien Lambrecht 1* , Bianka Kuhne 1 , Xavier Gellynck 1 1 Ghent University, Faculty of Bioscience Engineering, Department of Agricultural Economics, Division Agri-Food Marketing and Chain Management, Coupure Links 653, B9000 Gent, Belgium; *Corresponding author: firstname.lastname@example.com Innovation is widely recognized as being an important strategic tool for companies to increase their competitive advantage. Hereby, networks are an increasingly important external source for the necessary knowledge, ideas and financial resources. The main contribution of this paper is to shed light on how different network partners can explain or facilitate the different types of innovations in the agricultural sector. In contrast to other studies, we make a distinction between all four types of innovation: product, process, marketing and organizational innovation. Furthermore, we investigate the whole innovation journey, embracing the entire innovation process from inception to the implementation of the innovation. Thus, this study has the objective to gain insight into farmers' innovation journey and the role of interactions in networks for successful innovation in order to enable a better support of the sector's further development. The study is based on 28 in-depth interviews with farmers spread over five subsectors in Flanders (northern Belgium). For this research, the innovation journey analysis was used in order to capture the complex and contextual nature of the farmers' innovation journey. Our most important findings are that different network partners are required for different types of innovation and that sectors could learn from each other in particular for market and organizational innovation. Hence, our study delivers a first set of valuable insights and implications for farmers, network coordinators and policymakers. Farmers must be aware of the importance of partner suitability and network heterogeneity for the innovation type they are aiming at. Furthermore, farmers have to be aware of the fact that efficient networking is not the optimisation of single relationships independently of each other, but instead the management of synergies and coordination of all relationships in an efficient way. In addition, network coordinators should set up a clear strategy and communicate for which innovations their network can advise and help the farmer. These first conclusions should be further proven and supported by future research in order to draw general conclusions for the agricultural sector. As the sample of our study is limited to 28 respondents spread over five subsectors, it is necessary to increase the sample size to achieve a representable sample and to include more subsectors. In addition, the study is limited to the Flemish region and literature in other countries about this subject is scarce. Hence, other researchers are encouraged to investigate other regions in Europe and the world and compare them to the Flemish results.

Abstract : By law, the peacetime strength of the West German armed forces cannot exceed 500,000 soldiers; however, its waritime strength will grow to 1.34 million. Over 800,000 soldiers are members of the German military reserve system, with the majority assigned to the Territorial Army. Increased awareness by the U.S. of the rear area threat in the event of war in Germany, coupled with the commitment by the FRG to provide 93,000 Wartime Host Nation Support (WHNS) soldiers to reinforce U.S. forces, demands that we fully understand the contributions of the German Territorial Army (GTA). Realization that WHNS to U.S. forces is a direct responsibility of the GTA, and this support wil impact on how NATO forces wage war in the event of Warsaw Pact aggression, mandates the formal integration of the GTA into the NATO planning system. This essay shows that most of the groundwork to accomplish this goal has been accomplished. WHNS must become U.S. doctrine and must be presented in appropriate technical and field manuals that would foster a better understanding of the GTA, as: an Army that is structured identical to its Field Army counterparts; an Army that plans to have up to six of its Home Defense Brigades serving in Field Army divisions; and a force with its primary mission being the security of the Rear Combat Zone.


Abstract Although the research literature investigating the relationship between grade awarded to students and students' evaluations of teaching performance is voluminous, very few studies have examined the grade‐rating relationship according to level of student. The present study examined correlations between mean instructor rating and mean class grade for all course evaluations (N = 625 classes) at Utah State University during an academic quarter. In lower‐division (courses 100–299) and upper‐division (courses 300–599) undergraduate classes, correlations between grades and ratings of faculty were of an expected direction and magnitude (0.29 and 0.28, respectively); however, the grade‐rating correlation for graduate classes (courses 600 +) was — 0.20. It is speculated that graduate students are both better students and more critical evaluators of instruction, but replication and extension with different samples are needed before this tentative explanation can be accepted with confidence.


Formal similarity between −→ k − area for the contribution from ZR-states and the remnant Fermi surface has been found. Presence of the contribution from 3 B 1 g − states at other −→ k − area means the two-channel processes of scattering. As consequence, the method of integration with a constant energy interval reproduces not only remnant Fermi surface at least , but one of the contributions of above states to the total spectral intensity


The present research examines the impact of smiling on attitude change. Participants were first exposed to a story that elicited mostly positive thoughts (about an employee's good day at work) or negative thoughts (about an employee's bad day at work). After writing down their thoughts, participants were asked to hold a pen with their teeth (smile) or with their lips (control). Finally, all participants reported the extent to which they liked the story. In line with the self-validation hypothesis, we predicted and found that the effect of the initial thought direction induction on story evaluations was greater for smiling than control participants. These results conceptually replicate those obtained in previous research on embodiment (i.e., more favorable evaluations of stories when smiling; Strack, Martin, & Stepper, 1988) when participants had positive thoughts, but showed the opposite pattern of results (less favorable evaluations for smiling) for negative thoughts.


The Network security aims to protect the network and the network-accessible resources from unauthorized access. However, the dynamic characteristics of contemporary networks combined with their increased size makes the vision of absolute network security almost impossible. Specifically, networks are vulnerable to infection by different types of electronic attacks such as viruses, Trojan horses or eavesdroppers that exploits the loopholes in the security mechanisms of networks [FAGY00]. Guaranteeing an acceptable level of security for a prospective system represents a common problem in systems engineering. Network security, is defined as a Non-Functional Requirement (NFR) that is influenced by functional aspects of the system such as the specification of antivirus and firewall mechanism employed on the network. This area of research has gained considerable popularity due to the implications it has on users' satisfaction, business reputation and performance. Therefore, being able to quantify the security level of a future network early in the design phase is of vital importance to its sustainability. The need to validate security requirements early has been addressed also by Lamsweerde [CILN02] and Crook [L04].


This paper introduces work-in-progress to develop hybrid forms of drama-based and game-based learning using a web platform called Prospero (https://prospero.digital/). Suitable for face-to-face, online or blended delivery modes, Prospero builds learning activities by curating existing web and media content. This can then be overlaid with new in-browser controls and timeline events, on-screen instructions, and additional media elements created and shared by instructors and participants. Prospero is developed by UK arts company C&T (http://www.candt.org), recognised as world leaders in the field of technology-enhanced drama-based creativity and education. This paper introduces some of the features of the Prospero system, as experienced in the initial phase of a pilot project, titled "The Pop-Up Newsroom", which aims to promote news literacy using drama and game conventions. The project is also exploring the concept of "intermediality", which posits that our already multimodal and mediated lives are increasingly shaped by the exponential transformations of networked digital media. In particular, the project is seeking to understand the challenges and opportunities of learning and teaching in hybrid creative spaces that merge live performance, media arts, education, and digital cultures.


We have previously reported measurements of the maximum ventilatory capacity and the ventilatory requirements for a standard exercise in 26 patients with mitral stenosis (Stock and Kennedy, 1953). A small but variable reduction in maximum ventilatory capacity was noted which appeared to bear little relation to the severity of the patients' symptoms. On the other hand, it was found that increasing disability in mitral stenosis tended to be associated with an increasing ventilatory cost of exercise. We suggested that this increased ventilation might prove useful as

: A field experiment was conducted at the experimental farm, Faculty of Ag-riculture, Al-Azahar University, Assuit, Egypt which is located at 27  12 - 16.67 = N latitude and 31  09 - 36.86 = E longitude for two successive sunflower growing seasons of 2011 and 2012. This study aims to asses the effect of soil management practices (conventional, reduced and no tillage) at different soil moisture content (65 and 85 % of field capacity, F.C.) with two fertilizer types (urea and ureaform) on soil carbon dioxide flux in order to mitigate its effect on global climate changes as well as sunflower growth. The results indicated that the emitted soil CO 2 ranged from 12.49 to 22.65, 14.49 to 25.06 and 14.14 to 25.95 g/ 100 m 2 for no tillage (NT), reduced tillage (RT) and conventional tillage (CT), respectively at 65 % of F.C., with using urea fertilizer. The lowest emitted CO 2 values were observed in the second week while the highest ones were noticed in the 5 th week for NT treatment and in the 7 th week for RT or CT treatment. The trend line of CO 2 emission was less inclined under NT than under RT or CT tillage. The trend line of the emitted soil CO 2 under RT and CT treatments subsequently became approximately equal. The young growing plants at 85% of F.C. using urea fertilizer showed more CO 2 uptake than it at 65% of F.C. using ureaform fertilizer. The no tillage treatment (NT) had higher CO 2 flux than RT treatment at the beginning of the evaluation period (till 4 th week) and lower flux at the end. The trend line of emitted soil CO 2 from CT treatment showed almost a steady flux through the growing season (10 week), and the CO 2 flux values ranged between 17.71 and 25.40 g/ 100 m 2 . Sunflower grain yield was significantly affected by soil moisture content and fertilizer type as well as it was highly significantly affected by tillage manner. Sunflower grain yield was higher in the plots treated with ureaform at 65 % of F.C. than in those treated with urea at 85 % of F.C. It was superior under the conventional tillage followed by the reduced tillage then no tillage. On the aver-age basis, sunflower grain yield was 1.97, 2.01 and 2.22 ton/ fed for NT, RT and CT, respectively at 65% of F.C. However, it was 1.05, 1.76 and 2.22 ton/ fed for the respective treatments at 85 % of F.C.


In hardware implementation of any signal processing algorithm, computational time and hardware resources are crucial issues. This paper presents design and implementation of a new architecture of wavelet filter for power system harmonics estimation using discrete wavelet packet transform (DWPT). Usually, DWPT provides coefficients as the output, however, the proposed architecture also includes provision for providing rms values directly. The proposed method reduces computational requirements and save memory resources. Xilinx system generator, a higher abstraction level tool, has been used to simulate and implement the proposed scheme on the Xilinx Artix-7 FPGA AC-701 board. Performance of the proposed architecture has been validated and compared through hardware co-simulation with variety of synthetic and experimental signals.


The possible mode of deformation and microdamage due to contact stresses have been studied quantitatively on single wool fibres compressed against opening elements by extending a fibre looped around the element. By using scanning electron microscopy, the contact area of test fibres has been studied to assess the surface morphology caused by localised contact stresses built up at the contact area. The study showed that compressive stresses are built up over the contact area. Also, longitudinal and transverse cracks created in high speed sliver opening experiments, as reported in Part 1 of this series [1], were successfully reproduced in this controlled experiment. The cracks and compressive stresses observed strongly suggest the involvement of Hertzian contact stresses in ultimate fibre rupture. The effect of the rate of strain on fibre microdamage is discussed.


Natto, a traditional fermented food in Japan, is prepared by fermenting steamed soybean with Bacillus subtilis. It has been reported to exert antioxidant activities, and the inhibitory effect on angiotensin I converting enzyme (ACE) as well. In the present study, various solvent (water, 80% methanol, 80% ethanol, 80% acetone) extracts of B. subtilis BCRC 14715-fermented black soybean were examined for total phenolic, flavonoid, and anthocyanin contents as well as the antioxidant activities including 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals scavenging effects, reducing power, and Fe2+-chelating ability. Besides, effect of fermentation period and extraction solvent on ACE inhibitory activity of the Bacillus spp.-fermented black soybean extracts were also investigated. The results showed that the extract of the fermented black soybean exhibited significantly higher (p<0.05) total phenolic, flavonoid, anthocyanin contents and antioxidant activities than did the extract of the nonfermented black soybean. Among the various extracts examined, acetone extract showed the highest contents of total phenolic, flavonoid and anthocyanin. The methanol extract excerted the highest Fe2+-chelating ability, while the acetone extract showed the highest DPPH free radicals scavenging effects and reducing power. The inhibitory activity on ACE of bean and viscous material extracts of Bacillus spp.-fermented black soybean increased as the fermentation period was increased. Bacillus sp. CN11-fermented black soybean extract exhibited the highest ACE inhibitory activity. A higher ACE inhibitory activity was noted in bean extracted with 80% ethanol than with water. On the other hand, a significantly higher (p<0.05) ACE inhibitory activity was noted in the water extract of viscous material than the 80% ethanol extract.


Abstract Importance: Racial and ethnic minority populations have been disproportionately affected in terms of hospitalizations and deaths during the COVID-19 pandemic. Vaccine uptake remains a barrier to full population inoculation against this highly infectious disease. Objective: The purpose of this report is to describe SARS-CoV-2 vaccine interest rates in a racially, geographically, and ethnically diverse study cohort and characterize vaccine interest across a racially, ethnically, and geographically diverse study population. Design: This report describes responses to a survey administered between November 2020 and May 2021 using a community convenience sample through a partnership between the National Minority Quality Forum (NMQF) and Federally Qualified Health Centers (FQHCs) as part of the Minority and Rural Coronavirus Insights Study (MRCIS). Analysis of survey responses from 3,624 participants are provided. Results: Early data from the MRCIS cohort suggest that [SARS-CoV-2 vaccine hesitancy] is more prevalent in Black versus Non-Hispanic Whites survey respondents, and the Hispanic community has positive interest in the vaccine, to a similar degree as Whites. The persistent presence of [vaccine undecided] across different sites and racial/ethnic groups uncovers the need for more public health efforts to influence positive views about vaccination. Conclusion: These findings highlights the urgent need for interventional educational campaigns targeted at populations at risk of low vaccine interest. Focused efforts are needed to combat misinformation and explain vaccine safety and effectiveness to promote its uptake and avoid low inoculation rates. Public health communication must consider differences in population groups, regions, and social determinants of health to fully address vaccine uptake disparities and overcome alleged hesitancy. Key Points -Willingness to receive the SARS CoV-2 varies among minority populations. -[SARS-CoV-2 vaccine hesitancy] is more prevalent in the non-Hispanic Black population than the non-Hispanic White and Hispanic populations. -Public health infrastructure is needed in underserved communities for efficient assessment and targeted communication of public health priorities such as the SARS CoV-2 vaccination.


This paper evaluates a laboratory process for extracting, isolating, and identifying rubisco, an essential protein found in plant cells and an important catalyst during photosynthesis. Isolating rubisco from other proteins also found in plants requires a carefully planned series of laboratory procedures to separate the proteins on the basis of physical characteristics including solubility, electrical charge, and molecular size. In this study, ammonium sulfate precipitation was used to extract proteins from a sample of spinach leaves and to separate the proteins into two samples with different solubility characteristics. These samples were then subjected to ion exchange column chromatography using buffers with a range of salt concentrations to produce fractions with varying electrical charge characteristics. The resultant fractions were then analyzed via protein electrophoresis to determine the molecular weight of the isolated proteins, which were compared against the known molecular weight of rubisco. Fin...


Twelve brands of 250 mg ciprofloxacin tablets, available in pharmacies of Mexico were evaluated in order to establish the pharmaceutical equivalence. Ciprofloxacin, is a second generation quinolone, it is a broad-spectrum antimicrobial agent, widely prescribed in the treatment of infectious diseases. Identity, hardness, friability, disintegration, drug assay, uniformity of dosage and dissolution tests were performed following FEUM 8° Ed requirements. The dissolution profiles of tested brands were compared with the reference brand. Tested brands met with quality control specifications therefore they are pharmaceutical equivalences; however when we compare the dissolution profiles some of them were not similar to the reference brand.


Recently, a fast converging algorithm for use in network echo cancellers called proportionate normalized least mean squares (PNLMS) has been proposed (Duttweiler, 2000). In comparison to the normalized least mean square (NLMS) algorithm, PNLMS has got fast initial convergence speed and tracking when the echo path is sparse. The idea behind PNLMS was to update each coefficient of the adaptive filter independently of the others by adjusting the adaptation step size in proportion to the magnitude of the estimated filter coefficient. Unfortunately, when the echo path becomes dispersive, the PNLMS algorithm converges much slower than NLMS. In many simulations, it seems that PNLMS has an advantage only when the impulse response is close to a delta function. More recently, an improved PNLMS (IPNLMS) was proposed (Benesty and Gay, 2002). It performs better than both NLMS and PNLMS algorithms. In this paper, generalization of the reliable method from the IPNLMS algorithm to a proportionate affine projection algorithm (PAPA) (Gansler et al., 2000) is presented. Simulations with real speech signals show that proposed algorithm (improved PAPA) is better than NLMS, PNLMS and IPNLMS and not dependent on the nature of the impulse response.


The world runs on lots of software. For many businesses and domains, this results in more software elements to develop and maintain. The added software elements often make for greater software complexity, which leads, in turn, to increased need for coordination between multiple software teams that build, integrate, and test the software. This increasing complexity often aggravates the challenges of "large-scale" software. Achieving scalability means different things in different contexts. The Editor briefly reviews scale, discussed from three different perspectives: scope, people, and time. Scope is about capabilities in terms of added features, greater size, and increased complexity of the system the software serves. The category of people includes the scale of the development organization and the software users. The category of time relates to the expected life of the system. It is then noted that this issue of IEEE Software presents different perspectives of scale with two themes, thus viewing the topic of scale from the perspective of development as well as software property. Articles under the theme "Large-Scale Agile Development" look into scaling development teams in large projects and organizations using agile software development methods. Articles under the theme "Building Long-Lived Adaptive Systems" cover state-of-the-art developments related to automated adaptive approaches for engineering systems that stand the test of time.


This work presents a numerical investigation of the self-steepening
 (SS) effect on the soliton spectral tunneling (SST) effect in a photonic
 crystal fiber (PCF) with three zero dispersion wavelengths. Interestingly,
 the spectral range and flatness can be flexibly tuned by adjusting the SS
 value. When the SS coefficient increases, the energy between solitons and
 dispersion waves is redistributed, and the red-shifted soliton forms
 earlier in the region of long wavelength anomalous dispersion. As a
 consequence, the SST becomes more obvious. The findings of this work
 provide interesting insights in regard to the impact of the SST effect on
 tailored supercontinuum generation.


This paper presents the assessment of the effect of grid electricity on the micro enterprises in Ekiti State of Nigeria using four geographic locations as case study. Data for the research work were gathered through the use of questionnaires, and semi structured interview while secondary data were obtained from existing information available in reports and documents to supplement field data. It was discovered that the availability of grid electricity in Ekiti State will stimulate the establishment, growth and expansion of small and micro enterprises though the present epileptic supply constituted a bottleneck to development. Currently, most enterprises in Ekiti State relied on optional power generator plant to remain in business even when it causes high cost of production, air pollution and noise pollution.


In 2013, 49.1 million Americans lived in food insecure households. Of these, 15.8 million were children. As college students are excluded from national surveillance data, it is difficult to characterize the prevalence of food insecurity among this population. The purpose of this study was to determine the prevalence of food insecurity among undergraduate students and what characteristics are associated with food insecurity. Students (18‐24 years) were recruited from the ongoing College Health and Nutrition Assessment Survey at the University of New Hampshire (UNH). A 26‐item online survey was developed by combining the USDA 6‐item Short Form U.S. Household Food Security Survey, the USDA Child Food Security Survey, and 11 UNH‐specific questions related to food access. The survey was administered to all students enrolled in a general nutrition class in fall 2014 (n = 418); response rate=50.5% (n=211, 84% female). Survey results indicated 11.4% of students reported low food security and 6.2% reported marginal food security during their childhood. During the past 12‐months, 12.4% reported experiencing low food security and 5.7% reported marginal food security; 2.8% reported currently or previously receiving food assistance. Students who lived in on‐campus housing were more likely to report food security as compared to those living in off‐campus apartments (86% vs 57%, p<.05); no differences in race, sex, marital status or parents' education were observed between students who were food secure vs. insecure. The findings of this study suggest that food insecurity exists on the UNH campus and further research related to food availability and education is needed. Due to the lack of data, other college campuses may benefit from assessing food insecurity prevalence among students.


While it is good so see the subject of chronic pain given attention in CMAJ , the article by Collier reinforces unfortunate attitudes, that patients with chronic pain are "difficult" with problematic psychosocial elements.[1][1] The latter is an oft-repeated fallacy with no real foundation in

Vigna unguiculata Linn belonging to family Fabaceae are used trad itionally as appetizer, di uretic, laxative, anthelmintic. Seeds are coarse powdered and exhaustively with hot solvent (Soxhlet) extraction by ethanol and macerat ion with chloroform water I.P. Five concentrations (10 - 100 mg/ml) of ethanolic and aqueous extr acts were studied for anthelmentic activity by using Eudrilus euginiae earthworms. Both aqueous and ethanolic extracts showed paralysis and death of worms in concentration (10 - 100 mg/ml) dependent manner. Alcoholic extract of Vigna unguiculata showed signi ficant activity than aqueous extract. Piperazine citrate (10 mg/ml) and distilled water were included in the assay as standard drug and control respectively. The result showed seeds of vigna unguiculata possessed potential anthelmintic ac tivity. The seeds extract also showed presence of flavonoid s , and glycosides by preliminary phytochemical investigations.


Induction of estrus is an effective management tool for increasing the pregnancy rate in ewes, and there is a long estrus interval after lambing in spring in Small-tail Han ewe. In this study, norgestrel releasing intra-vaginal devices (PRID) and PRID + pregnant mare serum gonadotrophin (PMSG) were used for estrus induction in Small-tail Han ewe, and expression of follicle-stimulating hormone receptor (FSHR), luteinizing hormone receptor (LHR), estrogen receptor (ER) and progesterone receptor (PGR) mRNA in the ovarial stroma, oviduct ampulla and endometrium was analyzed by quantitative real-time PCR. The results showed that the estrus-induction with PRID and PRID + PMSG almost had the same effects on increasing the percentage of animals in estrus and conception rate of the ewes, and the estrus-induction had no significant effect on the expression of LHR, ER and PGR mRNA in the oviduct ampulla, ovarial stroma and endometrium, and FSHR in the ovarial stroma and endometrium. Furthermore, the estrus-induction could significantly decrease the expression of FSHR mRNA in the ovine oviduct ampulla (P<0.05). Therefore, it was suggested that down-regulation of FSHR in the oviduct ampulla after estrus induction may be helpful for fertilization and early embryo development.


A research program was undertaken to determine the effect of environmental factors on the efficiency of modern ski bindings. The method used was to apply pure moments and combined loads to skis mounted with various bindings. The loads transmitted to a simulated tibia were measured. Binding performance was measured before and after subjecting the binding to environmental conditions. The effects of dirt, ice, salt corrosion, vibration, and repeated use were studied. It was found that the ice test had the most serious effect on binding performance and that none of the tested bindings protected a simulated skier under all the environmental test conditions.


For the above-named work, which appeared on pages 692-700 of the October, 1966, issue of this Transactions, the paragraph on page 696 which contains Eqs. (1) through (3) is corrected, revising these equations.


Background Atherosclerosis is a common inflammatory disease. Stem cell and endothelial progenitor cell treatments can improve cardiac function after myocardial infarction. Granulocyte colony-stimulating factor (G-CSF) is a mobilisation agent, mobilising stem cells from the bone marrow to circulation in the blood. G-CSF may constitute a treatment of atherosclerosis. We have conducted meta-analysis to evaluate the current evidence for the effect of G-CSF on the progression of atherosclerosis in animal models and to provide reference for preclinical experiments and future human clinical trials of atherosclerosis treatment. Methods We searched several databases and conducted a meta-analysis across seven articles using a random-effect model. All statistical analyses were performed using Review Manager Version 5.2 and Stata 12.0. Results We found that G-CSF therapy was associated with reduced atherosclerotic lesion area (weighted mean difference (WMD): 7.29%; 95% confidence interval (CI): 2.06–12.52%; P = 0.006). No significant differences in total serum cholesterol (P = 0.54) and triglyceride levels (P = 0.95) were noted in G-CSF treatment groups compared with controls. Multivariable metaregression analysis revealed that the animal type (rabbit, P = 0.022) and frequency of G-CSF administration (>20, P = 0.007) impacted the atherosclerotic lesion area changes. Conclusion The meta-analysis suggested that G-CSF treatment might inhibit the progression of atherosclerosis in animal models.

In cooperative communication systems based on space-time block coded orthogonal frequency division multiplexing(STBC-OFDM),inter-channel interference(ICI) and co-channel interference(CCI) arise from multiple carrier frequency offsets(CFO) among different user nodes.Practical equalization methods are studied to combat these two interferences.When difference of normalized CFOs(DCFOs) is small,a low-complexity iterative approach named IAZF is proposed,which achieves zero forcing(ZF) equalization.In case of large DCFOs,a joint equalization algorithm(JEA) is given,which combines successive minimum mean square error(MMSE) inter-block interference cancellation with parallel interference cancellation.Furthermore,by exploiting the approximate banded structure of channel matrix,we implement recursive calculation of matrix inversion of JEA to reduce the computation burden. Simulation results show that,in a quite large range of DCFOs,JEA is robust with significant improvement over the existing methods,especially when DCFOs is larger than 0.25.The performance of IAZF approaches those of other methods when DCFOs is less than 0.15,and requires low computation load.

The research aimed to know the relation between self-regulated learning and creative thinking skills of elementary school students in the distance education during COVID-19 pandemic. Self-regulated learning and creative thinking skills are needed by elementary school students. They train the students' cognitive development during the learning process and prepare them for the next educational level. Teachers should guide, encourage, and implement appropriate learning strategies to improve the students' self-regulated learning and creative thinking skills. It employed a quantitative approach with ex post facto and survey methods. The sample was 121 elementary school students taken randomly in Sleman Regency, Indonesia. The data were collected using a Likert scale questionnaire. The results showed that the students' self-regulated learning level was in the moderate category, which was the highest frequency. The creative thinking skills also reached the same level and frequency. Further, self-regulated learning and creative thinking skills were correlated with a high correlation coefficient rate (R = 0.856). Therefore, it is recommended that teachers use a learning method that can activate and develop the self-regulated learning to increase the students' creative thinking skills.


All segments of the construction industry widely accept that energy-related issues have become increasingly critical because sources and management of energy are global and national priorities. Buildings use more than one-third of the energy consumed in the United States, and the heating and cooling of these buildings cost hundreds of billions of dollars annually. Properly insulating buildings is an effective method to reduce energy consumption without sacrificing comfort. And using proper insulation is in a nation's best interest because conserving energy can make it less dependent on oil imports.


In the realm of nite element discretizations of elliptic problems a basic distinction can be made between conforming and nonconforming methods. The latter rely on approximations not contained in the space the exact solution lives in. Since additional diiculties are thus introduced nonconforming approaches usually are a last resort: if satisfactory conforming spaces prove elusive they are given a try. For primal variational problems a mature theory of nonconforming methods has already been developed. This paper seeks to extend these ideas to the mixed formulation of second order boundary value problems. A \patch{test" is designed as a powerful tool for probing the viability of nonconforming approximations. In particular the criteria are utterly problem{independent. Consequently they can dispense with any regularity requirements.


In the era of the digital world. The communication and the use the internet is an important role in today's society. As a result, the number of users networks traffic increases but not enough resources for users causing users to receive inefficient services. Therefore, the network service provider must take action to fix the aforementioned problem. Forecasting is therefore necessary in order to determine the amount of network traffic in order to support the future increase in user numbers. Consequently, this research investigates to assess network traffic forecasts comparing the machine learning: Artificial Neural Network (ANN), Long Short-Term Memory (LSTM), and statistical methods: Autoregressive Integrated Moving Average (ARIMA), Simple Moving Average (SMA). The method of sliding window will be used simultaneously and evaluate the forecast and model performance using the MAE, MAPE, MSE, RMSE and R-square algorithms, respectively. The results show that machine learning forecasting is more effective than statistical forecasting. Because the error value is lower, the model can reliably anticipate data. Therefore, the results of this research are expected to help network service provider to improve their networks quickly and efficiently to accommodate the number of users that may increase in the future.


Magneto Motive Force is an important quantity to analyze winding harmonic effect. Indeed, the latter is directly linked to that of the air gap magnetic flux density and thus to the torque ripples, vibration and then noise. This paper proposes to reduce the MMF harmonic content by means of optimization process using mono-objective or multi-objective algorithms with discrete and continuous variables. To this aim, optimization algorithm is coupled with an analytical tool which allows quickly calculate the MMF harmonic content from winding parameters. A winding optimization is proposed to show the use of this method.


This article addresses itself to one question, although I hope it will summon others: what is the place of personal experience in contemporary feminist writing on the body? My concern is with issues involving how the body of the theorist is presented and interpreted within theoretical spaces. In particular, I want to draw attention to the difŽ culties of articulating eating-disordered bodies, and the speciŽ c problematic of writing a bulimic body. My discussion concludes with the incorporation of a narrativised account of my own experience of bulimia within this context.


A growing chorus of criminologists suggest that we are experiencing, as Russell Hogg puts it, a " . . . blurring of boundaries between domestic and external security, civil and military power, crime and war." Arguably, the blurring of these boundaries contributes to both changes and continuity in nation-states' criminal war-making. The recent Bush presidency justified foundational violence as a basis for foreign interventionism, for example, a trend continued by the Obama administration. In this larger troubling context, I find myself one afternoon on a long bus ride home from a wonderful anti-war weekend. I am stuffed in with three students from Iona College where I teach, in New Rochelle, New York. Two of the students are asleep, one with earphones in her ears. The third is awake, is also wearing earphones, and has his nose in a texting device. Iona College allowed me the opportunity to chaperone these three energetic people to Washington, D.C. for a four day "Spring Lobby Weekend," sponsored by Friends Committee on National Legislation (FCNL). FCNL describes itself as "a Quaker Lobby in the Public Interest." They claim to field the largest team of registered peace lobbyists in Washington, and describe themselves as a non-partisan group that works with many races, religions, and cultures to advocate for social and economic justice, peace, and good government. As a political sociologist and critical criminologist, I believe that politics is largely a matter of upper classes using their power to prevail over the producing and accumulating of material resources. Thus, being what some would call cynical, I was not initially impressed with the idea of spending a long weekend learning how to lobby Congress. From my astute and luminous perch far above the class struggle, lobbying with a few people for peace and justice seemed like trying to stop a volcano by pouring a few gallons of water into its crater. I was, however, impressed with the FCNL weekend's opening day event: a protest rally in front of the White House at which Daniel Ellsberg, Ralph Nader, and other heroes of the peace movement spoke out. The dramatic part of the day was when some of them calmly got themselves arrested. As they have done many times, they refused police orders to stop clinging to the White House fence with signs saying things like "War is not the Answer," and "End Imperial Delusion." In the next two days, the students and I were educated about peace issues by lobbyists, politicians, activists, and congressman Jim McGovern (D–MA).


When the illumination wavelength is comparable to the object size, one is in the Mie scattering regime. In this regime geometrical optics breaks down because of diffraction effects, and image data must be interpreted on the basis electromagnetic wave theory. Mie scattering problems are difficult to solve because the full vector form of Maxwell's equations must be solved subject to the appropriate boundary conditions, without the benefit of the short wavelength approximation. In this paper we present the essentials of Mie scattering theory, introduce algorithms for computing Mie scattering, and show how Mie scattering concepts can be used to image fast-moving microparticles by visible light.


Acanthopanax sessiliflorus fruits anthocyanins were prepared by vacuum freeze drying technology and the particle structure was studied. On the basis of single factor test the effects of drying pressure, material thickness and heating plate temperature on the drying anthocyanins were investigated by Box-Benhnken center composite design and response surface technology. The results showed that the optimum technical conditions were as follows: drying pressure 50 Pa, material thickness 8 mm and heating plate temperature 50°C. Under the optimum conditions, the drying rate was 19.37 g/(g·h), the anthocyanins retention rate was 82.88% and the moisture content was 4.13%. Scanning Electron Microscope (SEM) analyses showed that the anthocyanins were flaky particles, uniform particle size with smooth surface.


Current truncating circuit designs used in some controllable pulse width transcranial magnetic stimulation systems can be adapted for use with the peripheral nervous system. Such a scaled-down stimulator produces neuromuscular activation using less stimulus energy than described in previous reports of sciatic nerve stimulation. To evaluate the energy reductions possible with current truncation, we performed six <italic>in vivo</italic> experiments in rats where the magnetic stimulating coil abutted the sciatic nerve. We used electromyographic data to quantify neuromuscular response, with a criterion level of 20%-of-maximum to indicate a useful level of neuromuscular activation. The energy required to evoke this criterion response from muscles innervated by the sciatic nerve was reduced by approximately 34% from 10.7J with a stimulus waveform lasting 300<inline-formula> <tex-math notation="LaTeX">${\mu }\text{s}$ </tex-math></inline-formula> to 7.1J with a waveform lasting 50<inline-formula> <tex-math notation="LaTeX">${\mu }\text{s}$ </tex-math></inline-formula>. In water, the 300<inline-formula> <tex-math notation="LaTeX">${\mu }\text{s}$ </tex-math></inline-formula> pulse heated the coil by 0.30°C whereas the 50<inline-formula> <tex-math notation="LaTeX">${\mu }\text{s}$ </tex-math></inline-formula> pulse heated the coil by 0.15°C. Truncated-waveform magnetic stimulation systems can be used in basic research and clinical applications not requiring rapidly pulsed stimuli. An example of such a clinical application is left vagus nerve stimulation, a treatment that is reported to reduce epileptic partial-onset seizures.


Exception handling mechanism can increase the reliability of the system and improve the robustness of the software.However,incorrect application of exception handling mechanism will bring many potential errors,so it is necessary for exception handling constructs to be tested.A testing methodology is presented to identify the exception variables ''def-uses'' to be tested in the tested program,and test coverage of these ''def-uses''links is calculated by using an exception def-catch metric.Finally,a rough prototype tool for exception analysis and testing is designed.


Recent observations of the Galactic halo revealed ≈ 20 B-type stars moving over the Galactic escape velocity (e.g., Brown, Geller, & Kenyon 2014). Proper motions of these unbound hypervelocity stars (HVSs) indicate their origin in the centre of our Galaxy (GC). In the GC, another group of similar number of B-type stars known as S-stars is observed less than 0.04 pc from the central supermassive black hole (SMBH; e.g., Do et al. 2013). Long before their discovery, such two groups of stars were predicted by Hills (1988) as a natural result of breakups of binaries in the tidal field of the SMBH. The origin of these binaries and their transport to the vicinity of the SMBH, however, remain puzzling. In this work, we assume that the binaries were formed within an eccentric stellar disc around the SMBH (similar to that observed in the GC at distances 0.04 pc . r . 0.4 pc; e.g., Paumard et al. 2006). We qualitatively discuss the key properties of the HVSs and S-stars formed by tidal breakups of such binaries brought towards the SMBH by the Kozai-Lidov dynamics in the potential of the disc itself (for more details of the dynamics, see Haas & Šubr 2016).


The advent of powerful computers has played a central role in furthering our capabilities to solve complex Computational Fluid Dynamics (CFD) problems. Being able to store a large amount of information and use this information to execute numerous mathematical operations is integral to exploiting the complete utility of CFD. We have certainly progressed a long way from using basic panel-method-based techniques applied to simple bodies of revolution or discretizing Euler equations for crude twodimensional airfoils near zero angle of attack in the early 1960s, to tackling full aircraft configurations with separated flow through the use of the Navier–Stokes equations. The challenges in CFD have not been limited to aerospace applications alone, as marine scientists and other non-aeronautical researchers have shared the frustrations of turbulence modelling, accurately simulating transient phenomena fundamental to viscous flows, or even the inadequacies of background meshes to resolve the intricacies of small-scale effects. This paper takes a brief look at some of our current capabilities and provides some insights into the future directions of CFD. This includes such CFD challenges as the unsteady trajectory calculations of stores from moving platforms; timedependent rotor flow; missile performance studies, including heat transfer effects at hypersonic flows; icing studies; and the use of Large-Eddy Simulation and Direct Numerical Simulation techniques to resolve turbulence characteristics. Being home to the state-of-the-art wind tunnel facilities, the Institute for Aerospace Research CFD Group has made increasing use of the modelling techniques to augment and enhance the capabilities of our testing environment.

Image reconstruction algorithm for three-dimensional laser optoacoustic imaging system (LOIS) is proposed and tested in computer-simulating experiments. It was assumed that acoustic transducers were evenly distributed with 3-degree interval along polar and azimuthal angles on the surface of a 100-mm diameter hemisphere, all optoacoustic sources were located inside the hemisphere of a slightly smaller diameter. At the first stage of calculations, the initial data in a form of spherical surface integrals were converted into the plane surface integrals. We deduced an approximate analytical formula for this conversion. At the second stage, the three-dimensional Radon transform algorithm was applied for reconstruction of optoacoustic sources. Three- dimensional images of computer-simulated spherical objects were generated. Quality of reconstructed images was evaluated with the following four criteria: The noise level on the entire tomogram, the step-transfer function, the loss-of-contrast function and the contrast-dimension relation. These quality criteria may be employed to characterize any tomography systems regardless of the type of technology employed. Image analysis demonstrated that the artifact level associated with data conversion from spherical into planar coordinates did not exceed 10%. A 1-mm spatial resolution could be obtained with the proposed algorithm, provided the signal-to-noise ratio equals approximately 3 on the tomogram. Very small (0.5-mm diameter) and small (3-mm diameter) spherical tumors could be revealed on optoacoustic tomograms if their contrast equals at least 6 and 0.3, respectively.


This study is not to analyze thoroughly the digital narrative, but to comprehend its some characteristics. To develop the study, we chose a role playing PC game "Diablo Ⅱ". While following each levels of generative trajectory, we hope to observe these characteristics. In the deep structure, the semiotic square show us an axiology of the game. The conflict between the good and the evil dominate the deep structure of "Diablo Ⅱ". The narrative structure of this game have two characteristics; one is the simple constitution of the subject and object. The other is that the narrative program have many sub-narrative programs. The repeated aspect of sub-narrative programs constitutes the characteristic of the role playing PC game like "Diablo Ⅱ". In the discourse level, we can observe actorialization, spatialization and temporalization. It is interesting that we can find the quantitative increase of typical characters. Although the syntaxe of the spatialization and temporalization is relatively simple, it is difficult to find spatio-temporal mark in the game. We pointed out some characteristics of the digital narrative throughout "Diablo Ⅱ". It is not sufficient to show entirely the narrative structure of the PC game. But we are satisfied with approaching to explore the narrativity in the digital generation.


With the increased loading and exploitation of the power transmission system and also due to improved optimised operation, the problem of voltage stability and voltage collapse attracts more and more attention . A voltage collapse can take place in systems or subsystems and can appear quite abruptly. Continuous monitoring of the system state is therefore required. The cause of the 1977 New York black out has been proved to be the reactive power problem. The 1987 Tokyo black out was believed to be due to reactive power shortage and to a voltage collapse at summer peak load. These facts have strongly indicated that reactive power planning and dispatching play an important role in the security of modern power systems. A proper compensation of system voltage profiles will enhance the system securities in the operation and will reduce system losses. In this thesis, some aspects of reactive power dispatch and voltage control problem have been investigated. The research has focused on the following three issues: Firstly, the steady-state stability problem has been tackled where, a voltage collapse proximity indicator based on the optimal impedance solution of a two bus system has been generalised to an actual system and the performance of this indicator has been investigated over the whole range (stable and unstable region) to see how useful this indicator can be for an operator at any operating point. Then we went further to implement a linear reactive power dispatch algorithm in which this indicator was used for the first time to attempt to prevent a voltage collapse in the system. Secondly, a new efficient technique for N-1 security has been incorporated aiming at either maximising the reactive power reserve margin for the generators or minimising active power losses during normal as well as outage conditions (single line outage) .The reactive power redistribution after an outage is based on the S-E graph adopted by Phadke and Spong[72].Thirdly, the dispatch (N-1 security excluded) has been incorporated on line in the O.C.E.P.S. control package to improve the quality of the service and system security by optimally controlling the generator voltages (potentially the reactive control system is able to control transformers, switchable capacitors and reactors). A new function called load voltage control (similar to the load frequency control function) has been introduced to allow smooth variation of the reactive control signals towards their targets.


Puccinia reynoldsii sp. nov. is a new species encountered during mycological exploration on Clerodendrum indicum Kuntze from central Burma in the Pyinmana and the Gyobingauk townships. In this report, P. reynoldsii is described, illustrated, and discussed, based on traditional taxonomic tools.


Three nuclear electric propulsion (NEP) systems are discussed. The three systems are as follows: a system based on current SP-100 technology; a potassium Rankine-cycle based power conversion system, and an argon ion thruster system. The system will be researched for implementation in several possible vehicle configurations. The following are among the possible Mars vehicle configurations: a piloted 15 MWe multi-reactor vehicle; a piloted 10 MWe vehicle with ECCV; a piloted 10 MWe modular vehicle; piloted 10 and 15 MWe vehicles with ECCV and MEV; a piloted 5 MWe vehicle with ECCV; a 5 MWe cargo vehicle with 2 MEV's; and a 2.5 MWe vehicle with MEV.


Physicochemical and structural analyses were done of extruded snacks produced with two types of blue corn (hard and soft endosperm) combined with orange bagasse. Chemical composition, expansion index (EI), penetration force, water absorption index, and water solubility index values were calculated for all treatments. They were also analyzed with scanning electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. Addition of bagasse increased crude fiber content and hardness in the extrudates. It also lowered the EI, resulting in harder products with higher numbers of pores per area but of smaller sizes than in the extrudates without bagasse. Both the X-ray diffraction patterns and infrared spectra showed the starch to lose its semicrystalline structure due to mechanical shearing and high temperature. Orange bagasse was successfully incorporated into extrudated snacks made with blue corn of different endosperm hardnesses. Blue corn is a viable base for extruded snacks, and orange bagasse is a potential source of low cost, natural source fiber.


A hardware design of electric power meter with a wide current range is present.The accurate electric energy measurement of the impact loads is a research focus.Based on the research of impact load's characteristics,a wide range current measurement circuit that includes high accurate current transformers,programmable gain amplifiers,a 24-bit A/D converter,and a DSP was designed.The result of accuracy,EMC and environmental tests shows that the circuit accuracy can achieve 0.2S class and has an excellent reliability.The result of harmonic test that employing 6100A as a power standard source shows that the harmonic electric energy metering accuracy is also good.


Abstract In the first half of the twentieth century, as newspapers were the most important means of communicating information about current events, Canada became the world's leading producer of newsprint. Its neighbor, the United States, was its leading consumer and the top global newsprint consumer. European countries depended substantially on Scandinavian newsprint production, and many countries around the world lacked domestic resources to make paper. By 1940, some 60% of the newsprint used around the world crossed an international border as it moved from paper manufacturer to newspaper publisher, and more than 90% of that came from Canada. Even in peacetime, printing a newspaper in the mid-twentieth century was a geopolitical challenge. Once World War II broke out, outside of North America paper supplies were significantly constrained as import flows were disrupted. The US and the Canadians partnered to distribute newsprint around the world to papers deemed 'friendly' to Allied interests in Latin America, and this practice of strategically disbursing newsprint continued into the early Cold War period and extended to Europe. At the same time, the United Nations understood global newsprint shortages to be one of the primary impediments to promoting postwar democratization and development efforts, and the organization sought ways of encouraging both a more equitable global distribution of newsprint and projects that would enable countries in the Global South to manufacture paper from raw materials that were domestically available. In the World War II and Cold War era, newsprint was the material precondition for press freedom, and the US and Canada held tremendous sway over regional and local public spheres as their policymakers decided where and to whom that newsprint was to be distributed.


A multi-decadal change analysis of the irrigation ponds in Taoyuan, Taiwan was conducted by using multi-source data including digitized ancient maps, declassified single-band CORONA satellite images, and multispectral SPOT images. Supervised LULC classifications were conducted using four textural features derived from the single-band CORONA images and spectral features derived from SPOT images. Post-classification analysis revealed that the number of irrigation ponds in the study area decreased during the post-World War II farmland consolidation period (1945 – 1965) and the subsequent industrialization period (1970 – 2000). However, efforts on restoration of irrigation ponds in recent years have resulted in gradual increases in the number (9%) and total area (12%) of irrigation ponds in the study area.

Hydatid cysts are most frequently localized in the liver and the lungs, with cardiac localization being very uncommon. The clinical presentation is generally asymptomatic, and can be associated with serious complications such as arrhythmia and death. A 16-year-old female patient was admitted to our emergency service with complaints of abdominal pain. The computed tomography (CT) performed to identify abdominal pain etiology revealed a 70 mm cardiac cystic lesion and pericardial effusion. Using Magnetic Resonance Imaging (MRI), the cyst was determined to be anatomically located on the right ventricular inferior wall. Surgery was performed on the patient for the diagnosis of a cardiac hydatid cyst, and the patient was later discharged without complications. Cystic hydatid disease is endemic in Turkey. In this respect, it is important to bear in mind that the disease may also demonstrate cardiac involvement, and that this disease, which is capable of engendering serious complications, should be diagnosed at an early stage and treated accordingly.


Increasing power and reduced component size so-called the miniaturization of control units, justifies a growing requirement for the improved Thermal Interface Materials (TIM) for transferring heat from a die to a heat-sink (so-called slug-up concept). In order to investigate the reliability of this concept, it is necessary to consider the thermomechanical and dynamic behavior of TIM on the attached components and under different loading conditions. In this paper, a new method for End-Of-Life (EOL) testing of the slug-up components under random vibration loading is proposed. The design of this test set-up allows the resonance frequency measurements of electronic packages which are covered by TIM. The EOL results for slug-up capacitors and corresponding failure modes are explained using and resonance frequency measurements. The experimental results are compared with numerical results by FE modeling of slug-up capacitors. The resonance frequency dependency of TIM and its influence on EOL estimation and corresponding failure modes are discussed.


A number of novel isoindoline nitroxides have been synthesised using a variety of synthetic techniques. Several carbon-carbon bond forming methodologies, including the first examples of Heck and Sonogashira coupling applied to the isoindoline nitroxide class, were utilised to give novel robust aromatic frameworks. Palladium-catalysed Heck coupling of brominated nitroxides and ester-substituted olefins generates novel nitroxides possessing extended conjugation. Hydrolysis of the nitroxide esters gave the corresponding carboxylic acids, which showed enhanced water solubility. Sonogashira coupling of an iodo-isoindoline nitroxide gave several novel alkynesubstituted nitroxides in high yield. Subsequent coupling of a deprotected ethynyl nitroxide with aromatic iodides gave acetylene-linked nitroxides and an acetylene linked nitroxide dimer. A butadiyne linked dinitroxide was successfully synthesised via Eglinton oxidative coupling of two ethynyl nitroxides. The synthesis of a novel water-soluble dicarboxy nitroxide was achieved by base hydrolysis of a dinitrile. Functional group interconversion furnished anhydride and imide substituted nitroxides from the diacid. Subjecting the imide to the Hofmann rearrangement gave an unexpected brominated amino-carboxy nitroxide. The dicarboxy nitroxide and the brominated amino-carboxy nitroxide were both shown to have a protective effect on Ataxia-Telangiectasia cells, indicating a possible role as antioxidants in the treatment of this disease. A fluorescein nitroxide was successfully synthesised through the condensation of the anhydride substituted nitroxide and resorcinol. After limited success using a variety of other techniques, Buchwald-Hartwig amination was able to furnish a rhodamine nitroxide, via a triflate-fluorescein nitroxide. The extended aromatic nitroxides possess suppressed fluorescence and we have described these systems as profluorescent. The profluorescent nitroxides were found to have significantly lower quantum yields than the non-radical analogues and displayed a substantial increase in fluorescence intensity upon radical trapping, making them useful probes for free radical reactions.

In this paper, we suggest that the new volume of robust audio watermarking method protects form the MP3 compression attack, mostly used in audio field. Watermarks were inserted at the coefficients repeatedly from low frequencies to high frequencies after DCT transform in commonly used Cox's spread spectrum method. However, our method could be investigated losing frequency when MP3 attacks and make order by small amount of losing frequency and then insert watermarks rightly through statistical analysis. In the result about various sound clips, the suggested method have better performances than Cox's method by preserving watermarks and reducing distortions of the original sounds.


For high bunch intensities the beam-beamforce is strong enough to expect orbit effects if the two beams do not collide head-on but with a crossing angle or with a given offset. As a consequence the closed orbit changes. The closed orbit of an unperturbed machine with respect to a machine where the beam-beam force becomes more and more important has been studied and the results are presented in this paper.


A method for judging and positioning a pseudo base station based on reported information of a terminal includes the steps that after receiving a message, the terminal judges whether the message is a spam message or not according to key words and a mobile phone number; if yes, a message or voice service is triggered immediately; if network connection fails, the position is judged to be a suspected covering area of the pseudo base station; the longitude and latitude of the position are recorded through a GPS chip of the terminal, when network coverage recovers, the covering position of the suspected pseudo base station is uploaded to a base station; if the terminal supports a route test function, the updating time of the position area, retention and reselection parameters and area codes are stored at the same time, so that a network monitoring server accurately discriminates and draws the covering area of the suspected pseudo base station according to a great deal of information such as the longitude and latitude of the covering position of the suspected pseudo base station, wherein the information is reported by the base station and comes from the terminal or a route test terminal, and then the position where the pseudo base station is located is judged rapidly and accurately. The method is easy and convenient to operate, high in efficiency and good in accuracy and does not increase interfaces and signaling loads of the base station or a core network, and it is necessary to modify hardware configuration of the terminal and an existing communication protocol.


In this paper fully time‐dependent collisional‐radiative (CR) calculations are used to study the highly dynamic nonequilibrium anode plasma in a magnetically insulated‐diode experiment. The CR model for the C i–C iv atomic system is described in detail, including the radiative and collisional rates and the level structure of the system. The electron temperature is determined by comparing time‐dependent line intensities for C ii and C iii ions to calculations of level‐population ratios in which continuous particle injection from the anode surface into the plasma is taken into account. The electron temperature is approximately 7 eV. The time‐dependent injected fluxes and the fluxes accelerated away from the plasma for C i, C ii, and C iii are determined by inverting the coupled CR rate equations. The calculated extracted flux near the end of the pulse is consistent with the measured carbon‐ion current drawn from the plasma. Injection of excited particles is also investigated and is found to be important dur...


In California, first-generation table grape vineyards were planted on their own roots. But in recent years growers have been replanting onto acreage previously in grapes more often. Grafted plants are being sought to overcome nematodes and other site-related problems. We investigated the etiology of the decline and death of 'Redglobe' table grape scions propagated on different rootstocks, using a series of greenhouse and field experiments, and reverse transcriptase-polymerase chain reaction (RT-PCR) assays. We determined that a specific graft-transmissible agent was closely associated with declining young grapevines. The 'Redglobe' closterovirus that we identified was given the trivial name Grapevine rootstock stem lesion associated virus (GRSLaV).


The greatest part of African history related to the process of capitalist ex pansion has suffered two equally devastating processes: on the one hand, the very process itself — slavery and shipment to the America of millions of Africans — acted as a powerful erasor by physically removing people and then — during the so called formal phase of colonial rule — by drilling in the heads of the colonized that they have had no history since they had no documents.


The SCT is a silicon strip detector forming a part of the tracking system of the ATLAS experiment at the LHC. The tracking performance of SCT is influenced by several fundamental effects: multiple scattering, Lorentz drift, energy loss variation, noise occupancy, and δ-ray production. In this thesis, the task requested by the SCT detector group has been performed. Clusters containing a δ-ray, which are assigned to a track were studied on data samples, specially prepared for this purpose. A correction to the affected cluster positions was successfully developed. The correction to δ-rays has been implemented into the ATHENA reconstruction framework and its performance was evaluated. A meaningful usage of correction for the detector alignment has been proposed. The ongoing detailed verification of the performance within the event reconstruction is partially beyond the scope of the thesis work.


Abstract Moderate heating (473 K) under hydrothermal conditions of a mixture of NH4VO3, ethylenediphosphonic acid, and water in the molar ratio 1 : 0.57 : 500 leads to the synthesis of a light blue powder compound formulated (H2O)[V2O2(OH) {O3P(CH2)2PO3}] (labeled MIL-5). Its structure was solvedab initiofrom X-ray powder diffraction data and its symmetry is monoclinic (P21/m(No. 11)) with lattice parametersa=7.903(1) A,b=9.355(1) A,c=7.485(1) A,β=118.25(1)°,V=487.42(1) A3, andZ=2. The compounds neutral three-dimensional framework is built up from dimeric units of face-shared VO5(OH) octahedra linked by tetrahedral diphosphonic groups. The water molecules are inserted in the cavities of the structure.


In situ waste package performance experiments involving simulated (non-radioactive) defense high-level waste (DHLW) containers have been in progress since late 1984 at the Waste Isolation Pilot Plant (WIPP) facility. These experiments involve full-size, simulated DHLW containers of several metals and designs emplaced in the WIPP bedded rock salt. These test containers are surrounded by granular backfill (packing) materials, have in many cases been intentionally injected with brines, and are heavily instrumented. A majority of the test packages also contain nonradioactive DHLW borosilicate glass waste form, either within the container and/or outside of it. The primary purpose of these WIPP simulated DHLW experiments is to evaluate the in situ durability and performance of all waste package engineered barrier materials, and to perform package concept validation testing. Twelve of the test DHLW containers, emplaced in WIPP test Room B, have been in heated operation since 1985 and had a maximum surface temperature of about 190°C. These containers were recently retrieved, after about 3 years of heated exposure, for detailed posttest laboratory analyses of: general corrosion and metallurgical degradation, waste form and backfill materials alterations, and other rock salt-brine-barrier materials near-field interactions with the "repository" geochemical environment. Test canisters and overpacks made of ASTM Grade-12 titanium showed essentially no visible degradation in either the base metal or welds; cast mild steel A216/WCA over-packs have suffered some uniform corrosion. Significant degradation of the removed instruments and associated test apparatus has been found: pieces of stainless steel (both 304L and 316) apparatus have undergone extensive stress-corrosion cracking failure and non-uniform attack; Inconel 600-sheathed instruments have undergone both extensive uniform and localized (pitting) attack. Granular backfill materials have been significantly compacted by creep closure to about a density of 2 kg/m. Laboratory analyses are still in progress. Further details on these materials results plus instrumentation data and other in situ WIPP waste package test observations are discussed.


A wideband circularly polarized (CP) antenna with a single feed is proposed for use in global navigation satellite systems. Its primary radiation elements are composed of two orthogonal bowtie dipoles, which are equipped with double-printed vacant-quarter rings to allow direct matching of the antenna to a single 50-Ω coaxial line and to produce CP radiation. The crossed bowtie dipole is appropriately incorporated with a planar metallic reflector to produce the desired unidirectional radiation pattern as well as to achieve a wideband characteristic in terms of impedance matching and axial ratio (AR) bandwidths. The designed antenna was fabricated and measured. The prototype antenna with an overall 1.2-GHz frequency size of 0.48 λo×0.48 λo×0.25 λo produced a measured |S11| 93%) over the operational bandwidth.


Previous work suggests a negative association between obesity and academic outcomes, possibly driven by shared physiological pathways involving inflammation and hormones related to metabolism as well as learning and memory. Our study tested this hypothesis in low-income preschoolers using measures of obesity, school readiness, and biomarkers (leptin, interleukin-6 (IL-6)). In two studies, participants received comfort food to consume (pre-or post-task), comfort food as a gift (pre-or post-task), or nothing and completed a social pain or pressure pain task.


The anthropophilic and peridomestic female Aedes aegypti bites humans to suck blood to maturate fertilized eggs, during which dengue virus can be spread between mosquito and human populations. Besides this route of transmssion, there is possibility of dengue virus being passed directly to offsprings through transo- varial transmission. After biting humans, fertilized eggs are laid in appropriate recipients (breeding sites). These eggs can hatch in contact with water releasing larvae, or can be stored in a dormant state (quiescence), which last for extended periods. Mosquitoes and humans are coupled in order to assess the dynamics of dengue virus transmission taking into account both horizontal and verti- cal transmissions. With respect to transovarial transmission, the influence of stored eggs is assessed (1, 2).


Background It has been clearly demonstrated that angiotensin(1–7) potentiates the vasodilating effect of bradykinin in isolated vessels of animals. Objective To investigate the interaction between angiotensin(1–7) Ang(1–7) and bradykinin in human forearm resistant vessels of normotensive healthy men in vivo, by the measurement of forearm blood flow using venous occlusion, strain-gauge plethysmography with intra-arterial infusions of peptides in a placebo-controlled, double-blind, cross-over design. Methods In eight men, bradykinin was infused intra-arterially twice; placebo, Ang(1–7), or angiotensin II was co-infused with the second infusion. The effect of inhibition of nitric oxide synthase on the interaction between Ang(1–7) and bradykinin was also tested in eight other individuals. The effects of Ang(1–7) were analyzed by analysis of variance (ANOVA) and by the ratios of individually derived areas under the dose–response curves (AUC) of bradykinin, adjusted for changes in the AUCs by repeated infusions of bradykinin with placebo. Results Ang(1–7) (1000 pmol/min) significantly potentiated the vasodilating effect of bradykinin compared with the effect of saline (P = 0.0471, ANOVA) and in a dose-dependent manner (adjusted AUC ratio [95% confidence interval (CI)] 2.75 (1.72 to 3.78) with 1000 pmol/min, 1.62 (1.31 to 1.93) with 100 pmol/min, and 0.98 (0.80, to 1.09) with 10 pmol/min). This effect was completely abolished by co-infusion of NG-monomethyl-l-arginine [AUC ratio 0.98 (0.90 to 1.04)]. Ang(1–7) did not affect the vasodilating effects of either acetylcholine or sodium nitroprusside. Conclusions Ang(1–7) potentiates the vasodilating effect of bradykinin, possibly through a mechanism(s) involving nitric oxide release, in human forearm resistance vessels.


The protection effect of several cryoprotectants on the freeze dried Lactobacillus starter was studied by measuring the viable cells' number and activity of lactate dehydrogenase after the starter was activated in liquid media.The results indicated that 10%~15% skim milk,and 10%~15% algar have a better protecting effect on Lactobacillus helveticum starter.


Background: Breast cancer is a heterogeneous disease comprising a diversity of tumor subtypes. All of them differ from each other resulting in a wide array of clinical pictures, risks of recurrence and response to treatment. In recent years, tumor biomarkers have changed the way breast cancers are diagnosed and treated. In this paper we have sought to investigate the differential expression of ANXA1, a multifunctional calcium binding protein, among various molecular subtypes of breast cancers and in particular triple negative tumors. Methods: ANXA1 was first studied using in-silico analysis on available DNA microarray and RNA sequencing data of human breast tissues. Next we ascertained ANXA1 expression on cell lines and breast carcinoma tissue microarrays along with cognate normal breast tissue. Results: Whereas ANXA1 expression is normally restricted to the normal myoepithelial cell layer it becomes ectopically and aberrantly expressed in tumor cells of a significant minority of aggressive breast cancers. Specifically, we found that ANXA1 expression is severely deregulated in high-grade breast cancers that comprise clinically aggressive tumors such as triple-negative and, to some extent, HER2-positive breast cancers. Conclusion: Our results indicate that ANXA1 is a valuable breast cancer biomarker that can help to segregate and dissect out subsets of high histological grade breast cancers paving the way to a better understanding of breast cancer progression and metastasis.


We demonstrate an inkjet-printed temperature- and humidity-resistant black phosphorus saturable absorber, enabling stable continuous mode-locking over 210 hours. Our work highlights the potential of BP-based devices for photonic applications operating under challenging environmental conditions.


We demonstrate an efficient and controllable way to roll up graphene oxide sheets into micro/nanoscrolls, where the rolling process is highly enhanced by nanoparticle aggregation. Nanoparticles like Ag and Fe3O4 attached onto graphene oxide sheets can help the rolling process, which may be expected to expand into other inorganic nanoparticles.


Changes in transparency and color as well as GHCl values of hard PVC foils exposed to gamma radiation were investigated while using different amounts of the stabilizers ethylene glycol bis-β-aminocrotonate (I), calcium/zinc laurate + epoxy compounds (II), and magnesium/zinc stearate + sorbitol + epoxy compounds (III), and plasticizers dioctyl phthalate (DOP) (IV), dioctyl sebacate (V), propylene glycol polyadipate + octyl alcohol composition (VI), and diisotridecyl phthalate (VII). A strong synergistic effect was observed in systems containing both plasticizer and stabilizer. Best results were obtained for the I + II + IV, I + II + V, and I + III + V systems.


Condenser tubes are mainly produced by precision extrusion with a porthole die and are used in the flow pass of refrigerant cooling systems in automobiles. For condenser tubes, the recent goal has been to develop a tube that has high strength allowing for multi-cellizing, flattening and minimizing the thickness of its walls to increase the heat transfer area and heat efficiency. This study was designed to produce Al3003 condenser tube has been produced in industrial practice, including extrusion die design, inspection of die design through the results of FE simulation and performance of trial extrusion. Chamber shape dimension and initial temperatures of tool and die is a variable in this paper. The validity of simulated results was verified into extrusion experiments on the condenser tubes.
