ABSTRACT: The Latino population in the United States has increased dramatically during the past several decades. However, Latino-owned businesses have been understudied. Even less is known about these firms' spatial distribution. Built on an interdisciplinary literature on industrial locations and ethnic economies, this study examines how the development of ethnic minority–owned businesses is contingent on the local neighborhood as both a work site and habitat. Using a confidential national survey of ethnic minority–owned businesses in the United States, this study compares the spatial distribution of Latino-owned employer firms in the Miami and Atlanta metropolitan areas. Consistent with previous research, results from this study strongly reinforce the importance of a connection between ethnic population concentration and emergence of ethnic businesses. A concentration of local businesses and co-locating with other businesses, regardless of ethnicity, are very important as well. Such agglomeration effects seem particularly important for new immigration destinations like Atlanta where a favorable entrepreneurial environment is still being developed for ethnic minority businesses. However, the positive effects from co-locating with local businesses are not linear. A threshold effect and small count preferences are detected in the two study areas.

Economic competitiveness is today, more than ever, related to business innovation capacity. Given this fact, the present paper offers an insight into the contemporary pattern of innovativeness of small and medium size enterprises (SMEs), which often represent the most dynamic actors in national economies. The findings presented here, and the related theoretical notions, are discussed from the aspect of regional diversity in the context of a globalised sector: the information technology (IT) industry. The strategies of Greek SMEs are compared to those of their IT counterparts in three European countries (U.K., Italy, Israel) and two East Asian countries (Taiwan, Korea). Furthermore, an in-depth analysis of the Greek IT SMEs, based on a qualitative survey , is also presented.


This article sets out to critically examine whether and how different ideas of (radical and liberal) empowerment are embedded in policy documents and texts pertaining to the introduction programs in Scandinavia. All three countries have several elements in the program that have the potential of being empowering, viewed from both a radical and liberal empowerment ideology. However, the liberal empowerment ideology is more present in the programs, to various degrees, compared to the radical empowerment ideology, which is more difficult, if not impossible, to live up to within the framework of all three programs.


For the existing image semantic segmentation algorithms that have some difficulties, such as small target missing segmentation, false segmentation, and imprecise boundary segmentation, an optimized DeepLabV3+ image semantic segmentation algorithm is proposed. Firstly, the backbone network selects Xception_65 and Xception_71 networks. After comparison, the Xception_71 network is selected; Then, a parallel multi-branch module (PMB) is proposed, and the hole convolution with hole rates of 6, 12, and 18 in the Atrous Spatial Pyramid Pooling (ASPP) module is changed to the hole convolution with hole rate of 4, 8, 12 and 16, to obtain low-level feature map data. The result will be better and ensure the high accuracy of image segmentation; In the decoding layer, the direct up-sampling multiple of the DeepLabV3+ algorithm will lead to the loss of pixel information in the image. Therefore, using a bilateral up-sampling decoder to increase the continuity of pixel information in the image; Channel attention is added to emphasize important features so that the model has a stronger generalization ability. The focal loss function is selected to eliminate the difficulty of sample imbalance in the segmentation target. Finally, experiments confirm that the mIoU value of the proposed method on the data set PASCAL VOC2012 reaches 85.4%, and the segmentation effect is significantly enhanced.


This article describes the educational practice of engineering student in Bangladesh, especially how they are still practicing the old and conventional way of learning, mainly by memorizing the entire subject they learn and push them to answer the question exactly as written in the book. This phenomenon brings the student to fixate on the book and will inhibit their creativity and innovation notions, even though without considering the effort to hone the students' creativity and innovation domain, the knowledge will not develop properly, including in engineering. Trough this research the total quality management (TQM) had been developed to lead the students to get a better and satisfying result of study without losing the effort to develop their creativity, innovation and research skills as important factor and main purpose of engineering education.

As we enter the second decade of the 21 st century, the question of what we do and why we do it as CYC workers cannot be ethically separated from the lived suffering, social and cultural marginalization, and direct oppression of the young people with whom we engage. The fundamental question is whether we accede to the demands of an ever more indifferent and brutalizing system of abstract economic rule, or respond with new forms of value, ways of living and caring for one another. This article will propose a framework of revolutionary love in partial response to these questions. The article will present a theoretical framework for a politics of Child and Youth Care premised in the post-Marxist writings on love and capitalism in the work of Gille Deleuze, Felix Guattari, and Antonio Negri.


The present article aims to study the effect of silver deposition on photocatalytic activity of the TiO_2/Ti with micro-arc oxidation.In order for the Titanium oxide coatings to be formed on the titanium net surface by micro-arc oxidation(MAO) in Na_3PO_4 solution with an AC power supply,it is necessary to use the photodeposition method to prepare the Ag/TiO_2/Ti phtotoatalyst with varying Ag loadings.In doing so,it is necessary to characterize and evaluate the structures and photocatalytic ability of titanium oxide coatings before and after the surface AgNO_3 photodeposition is treated by XRD,SEM,EDX and photocatalytic degradation of direct fast blue aqueous solution,respectively.The results show that the titanium oxide film is mainly made of titanium and anatase.Meanwhile,the titanium oxide films photocatalytic activity proves to be related with electrolyzed time and its photocatalytic degradation rate is low for the anatase content at the titanium oxide film surface.In this condition,the Ag loading can help to enhance the TiO_2/Ti films photocatalytic activity greatly.When AgNO_3 aqueous concentration is 2 g·L~(-1) and photodeposition time is 30 min,the TiO_2/Ti films photocatalytic degradation rate will increae from 9.8% to 26% in 120 min.

Declarations of interests made at meetings in the period 16 November 2018 - 27 November 2019. This indicate a conflict of interest with respect to one of the topics being discussed.


The distribution of elements in human spinal cord was investigated on unfixed frozen cord material using PIXE technique. Distribution of Cu, Zn and Fe were not uniform in the cross section of the spinal cord and concentrations of these elements were higher in the anterior gray horn than in the other areas, while K and Cl distributed uniformly. The content of K changed along the spinsl cord from the cervical to the lumbar level. These findings are discussed in relation to current understanding of the physiology of the spinal cord.


1744 Communications to the Editor ble; however, the BAL fluid grew Mycobacterium kansasii. The patient was started on a triple antituherculotis drug regimen. Follow-up chest radiographs showed a decreasing but persistent airfluid level up to four months after the BAL procedure. Sarcidosis is frequently associated with large fibrocystic spaces that cmmunicate with the airways. It is surprising, therefore, that BAL has not been reported to he associated with the development of an air-fluid level in these cystic spaces. The reasons for this are not entirely clear. In this patient, contributing factors may include the unusually large size and gravity-dependent location of the cystic space, the instillation of large volumes of lavage fluid, and the presence of superimposed M kansasii infection. We would like to advise caution when performing BAL in patients vith large fibrocystic spaces in the dependent segments of the lungs.


In this paper, we propose a novel explanatory framework aimed to provide a better understanding of how face recognition models perform as the underlying data characteristics (protected attributes: gender, ethnicity, age; nonprotected attributes: facial hair, makeup, accessories, face orientation and occlusion, image distortion, emotions) on which they are tested change. With our framework, we evaluate ten state-of-the-art face recognition models, comparing their fairness in terms of security and usability on two data sets, involving six groups based on gender and ethnicity. We then analyze the impact of image characteristics on models performance. Our results show that trends appearing in a single-attribute analysis disappear or reverse when multi-attribute groups are considered, and that performance disparities are also related to non-protected attributes.

The study referred to Verdict No. 1/ Actio Paulina/ 2011/ Commercial District Court of Makassar. The object of this research is to analyze the legal implications of the cancellation of legal deeds of Debtors who have been declared bankrupt and know the authority of the Curator in performing its functions and roles after the decision of bankruptcy stipulated by the court. The research method used is normative with secondary data as a data source, which analyzed qualitatively and the results are presented descriptively. The results shows the creation of legal certainty in Article 41 paragraph (1) Law Number 37 Year 2004 about Bankruptcy and Suspension of Debt Payment Liability. Moreover, it also implies to the bankrupt assets itself, to refund the money back to its original state and to be in the control of the Curator for later handling and/ or ordering of bankrupt property. In performing its functions and roles, curator's authority is enormous. Therefore, there will be provisions on the obligations of the Curator to report all activities and policies issued to Supervisors in the future.


Germanium exhibits high sensitivity to short-wave infrared (SWIR) and X-ray radiation, making it an interesting candidate for imaging applications in these bands. Recent advances in germanium processing allow for high-quality charge-coupled devices (CCDs) to be realized in this material. In this article, we discuss our evaluation of germanium as an absorber material for CCDs via fabrication and analysis of discrete devices such as diodes, metal-insulator-semiconductor capacitors, and buried-channel metal-oxide-semiconductor field-effect transistors (MOSFETs). We then describe fabrication of our first imaging device on germanium, a 32 × 1 × 8.1 μm linear shift register. Based on this work, we find that germanium is a promising material for CCDs imaging in the SWIR and X-ray bands.


Through the design of the progressive die for the cover gate, the structure and the working process of the mechanism of automatic feeding for the progressive die that realized by utilizing the back_and_forth action of the sliding block of the pressing machine were introduced.


Subtalar dislocation, also known as peritalar dislocation, refers to the simultaneous dislocation of the distal articulations of the talus at the talocalcaneal and talonavicular joints. Subtalar dislocation can occur medially or laterally with resulting deformity. Medial dislocations comprise up to 85% of subtalar dislocations whilst lateral subtalar dislocations are less frequent and in 15% to 20% of dislocations. Closed reduction and immobilization remains the treatment of choice. The tibialis posterior, talar head impaction, and entrapment of the joint capsule may cause difficulty in closed reduction of lateral dislocations; hence open reduction may be necessary. This case report presents an unsuccessful closed reduction of a lateral subtalar dislocation which required an open reduction technique using wire stabilization.


Contentious politics, in Tilly's sense, involves multiple relays of interaction (Tilly & Tarrow 2008). Activists interact amongst themselves, both within and between "social movement organizations" (SMOs); they interact with opponents and elites; with police and other security forces; and often also with journalists and even academics. The outcome of contentious politics is generated by these interactions and the concept of "fields of contention," as coined by Crossley (2003, 2006), is intended to capture the network which they form.

We study the Josephson transport in a highTc superconductor /ferromagnetic-insulator(FI) /high-Tc superconductor numerically. We found the formation of aπ-junction in such systems. More remarkably the ground state of such junction alternates between 0andπ-states when thickness of FI is increasing by a single atomic layer. We propose an experimental setup for observing the atomic-scale 0π transition. Such FI-based π-junctions can be used to implement highly-coherent quantu m bits.


Additive manufacturing (AM) may have many advantages over traditional casting and wrought methods, but our understanding of the various processes is still limited. Computational models are useful to study and isolate underlying physics and improve our understanding of the AM process-microstructure-property relations. However, these models necessarily rely on simplifications and parameters of uncertain value. These assumptions reduce the overall reliability of the predictive capabilities of these models, so it is important to estimate the uncertainty in model output. In doing so, we quantify the effect of model limitations and identify potential areas of improvement, a procedure made possible by uncertainty quantification (UQ). Here we highlight recent work which coupled and propagated statistical and systematic uncertainties from a melt pool transport model based in OpenFOAM, through a grain scale cellular automaton code. We demonstrate how a UQ framework can identify model parameters which most significantly impact the reliability of model predictions through both models and thus provide insight for future improvements in the models and suggest measurements to reduce output uncertainty.

AMP‐activated protein kinase (AMPK) is a serine/threonine kinase that was shown to phosphorylate eNOS at ser1177 and also at thr495. Although the role of AMPK in the vascular system has been the recent subject of much investigation, its role in erectile tissue has yet to be defined. Using a pharmacological approach, our objective was to elucidate its role in the corpus cavernosum. A concentration response curve (CRC) to 5‐aminoimidazole‐4‐carboxamide‐1‐b‐riboside (AICAR), a known AMPK activator, in phenylephrine (Phe) contracted corpus cavernosal strips did not cause relaxation, even at high concentrations (3mM). However, with AICAR (1mM) pre‐incubation, an increase in phenylephrine‐mediated contraction was observed compared to control (1.22±0.06 vs. 0.71± 0.03). The CRC to U‐46619 (a thromboxane receptor agonist) and endothelin‐1 did not show any significant difference in contraction between the two groups. However, with AICAR pre‐incubation, there was a significant attenuation of acetylcholine‐mediated relaxation (57.17± 2.87 % in Aicar vs. 71.66± 2.53% in control) and also relaxation mediated by sodium nitroprusside (43.24± 2.59 % in Aicar vs. 60.01± 2.47% in control). We speculate that activation of AMPK in penile tissue leads to phosphorylation of eNOS at Thr 495 producing inactivation of eNOS. Thus, NO bioavailability is reduced resulting in decreasing relaxation and increasing contraction.


departments that made 'Cold War' policies towards the region, such as the Department of State, the Pentagon, and the Central Intelligence Agency. Lowenthal argues that in the 1990s the US Treasury, Commerce, Agriculture, the Export-Import Bank, the Drug Enforcement Administration, the Environmental Protection Agency, and the Immigration and Naturalization Service, will gain influence in the policy formulation process, reflecting the issues on which this volume chooses to concentrate. Though social and economic issues now seem to be the focus of the analysis of the inter-American relationship, Cavarozzi provides a caveat to the chapter on the Latin American Left, that US intervention in the future may be conducted less for ideological reasons than for a ' combination of a crucial issue such as drugs or oil and "bad behaviour" as defined by US officials...' (p. 124). While US policy may develop beyond the various facets of the Monroe Doctrine to a more cooperative hemispheric relationship, as Augusto Varas argues, the coercive aspects of US intervention continue through unilateral invasion, covert action and current drug policies (p. 5). The volume is a valuable contribution to understanding inter-American relations. It is especially welcome in a time of change in the international system. Many of the structural conditions and issues confronting the region have not changed drastically with the end of the Cold War, yet the potential for change is uncommon. The book demonstrates that the issues are connected and the social, economic and political problems cannot be addressed individually. As far as interAmerican relations are affected, it is uncertain if the United States will invest in solutions that coordinate these interrelated problems.


The objective of the study was to assess the phenotypic characteristics of one of the most promising dairy cattle (Erashy cattle) in eastern Sudan. The present investigation was carried out in Elgash area, Kassala State. Animal's data were collected from118 mature cows. The coat colors varied between white, bright red brown, and multi color, represented 63%,32% and 5% respectively. The color of eyes and eyelids are black, eyelids are white and brown, eyelashes are white and black, the tip hair are black and the hoof are black, brown. The muzzle, brown and black, represented 95%, 54%, 33%, 13%, 68.6%, 31.4%, 70%, 40.7%59.3%, 40% and 60% respectively. Dewlap is well developed in all studied animals, goes down in front of the forelegs forming few folds, and it is predominant in both sexes. Hump extended in male and restricted in female, and may be cervical or cervico–thoracic. The temperament of the animals concerned was varied from docile to aggressive.

Data was analyzed by using completely randomized design to compute analysis of variance. For meaningful comparison, least significant difference (LSD) test were performed. Analysis of variance revealed that there were no significant differences among animals under this study except some of them, like Heart girth and Pelvic width at significant differences (P


In error-correcting codes for combating noisy transmission channels, a central concept is the notion of minimum distance. If a code can be constructed with minimum distance between code points of 2m+ 1, then any number of errors per code word which does not exceed m can be corrected, thus increasing the reliability of transmission above that to be expected with no redundancy in the code.

An upper bound on minimum distance is derived which depends on g (the number of code points or messages required) and n (the number of binary symbols per code point). This bound is complementary to a bound due to Hamming and uses an argument which is essentially due to Plotkin.

Construction methods are presented for codes which actually achieve the upper bound on minimum distance for any g and an infinite class of integers n which depend on g. Sixteen code types are described: three for g=2h-1 six for g=2h and seven for g=2k.


We study a numerical method for the diusion of an age-structured population in a spatial environment. We extend the method proposed in [2] for linear diusion problem, to the nonlinear case, where the diusion coecients depend on the total population. We integrate separately the age and time variables by nite dierences and we discretize the space variable by nite elements. We provide stability and convergence results and we illustrate our approach with some numerical result.


This research is the first to evaluate brittle wort (Chara corallina) extract for phytochemical content and inhibitory effects against a-glucosidase and a-amylase activities. An ethanolic extract of C. corallina had the strongest enzyme inhibitory effect. The inhibition efficiencies of all extracts against a-amylase were more potent than those against a-glucosidase, with IC50 values of 8.43±0.18 mg/mL against a-glucosidase and 1.78±0.07 against a-amylase. Inhibition efficiency was related to total phenolic content, DPPH radical scavenging activity, ATBS radical scavenging activity and metal-chelation activity of the extracts. Phytochemical screening of the ethanolic extract demonstrated the presence of the triterpenoid β-sitosterol. These findings provide useful supporting data for further applications of C. corallina extract.

A new method for order reduction of singularly perturbed discrete systems is derived. The discrete system is reduced to its dominant and parasitic parts. This method can exactly exhibit the responses of the original system. For control law design, the linear model-following control (LMFC) method is applied. The order of the model is chosen the same as that of the dominant part of the plant, i.e. we apply to the plant with and without parasitics the same LMFC law. The conditions for reduced-order LMFC systems are derived and some simulation results are illustrated


This report analyzes the impact of federal budget decisions between 1982 and 1985 and those proposed for the next three years on the organizations that make up the nation's private, nonprofit sector. These organizations have been ignored in both public policy debates and scholarly research. As a consequence, crucial features of their operations have not been well understood, including the extent to which government agencies have turned to nonprofit organizations to help deliver publicly financed services and the extent to which government budget decisions affect the revenues of these organizations.


Corrosion attacks steel buildings mainly when the connections wait for welding on site. In the companion paper, the effects were investigated by a series of weld tests. The results show that the surface rust may increase the level of porosity in steel welds, reducing the strength by 5% on average. This paper made a case study, further investigating the effects together with those of workmanship. The seismic risk of the example building has been assessed and compared in detail for acceptable and marginal quality workmanship. The results obtained from the above studies will help develop more sound strategies in construction management and building renovation.


Spacecraft autonomy is essential for managing unpredictable anomalies and reducing spacecraft operation costs. Autonomous systems proposed up to now can be classified into two types of approaches, that is, autonomy on the spacecraft and autonomy on the ground. The advantage of the former is that it can monitor all status of the spacecraft in real time and can quickly handle anomalies without ground station interaction. However, due to the limitation of onboard calculation capability, such system lacks some important aspects, for example, flexible modeling capability and optimality in the generated plan. On the other hand, the latter can take full advantage of its rich calculation resource, but these systems can not deal with the anomalies outside of the visible time. On that premise, this paper aims at constructing an integrated autonomous system that has both considerable calculation performance and real-time fault handling capability by coordinating the onboard system and the ground system and compensating for the weaknesses on both sides. In this integrated system, the ground station system with its high calculation performance generates a plan (activity sequence) according to the high-level goals set by human operators and sends it to the satellite. On the other hand, the onboard system, taking advantage of the fact that it has real time onboard status, executes the received plan and monitors the execution results at runtime. If any errors occur and the current status is not what is expected by the plan, the onboard executive regenerates without ground station intervention a minimum temporary plan which is applicable only until it gets support from the ground station. At the beginning of the next pass, onboard executive sends the current status to the ground, and then the ground system regenerates a plan and sends it back to the satellite. This system will be demonstrated on a remote-sensing nano-satellite "PRISM" which is being developed at University of Tokyo and is scheduled to be launched in mid-2006.


A new species of Indian striped Ichthyophis is described on the basis of six specimens from near the Western Ghats town of Madikeri, southern Karnataka (where it is sympatric with its congener I. beddomei), plus a seventh specimen of less certain provenance. The new species is distinguished from all other striped Ichthyophis by its combination of color, numbers of annuli and teeth, position of tentacular aperture, and the distribution and numbers of scale rows. A dichotomous key is provided to separate the four striped species of Ichthyophis of the Western Ghats.


In the field of digital sampling, disk jockeys have shown a recent enthusiasm for 'mash-ups' — new compositions created by combining the rhythm tracks of one song and the vocal track of another. Most famously of all, DJ Danger Mouse remixed the vocals from Jay-Z's The Black Album and the Beatles' White Album and called his creation The Grey Album. The Grey Album poses a number of difficult issues regarding copyright law and digital sampling. Does such a 'mash-up' go beyond the de minimis use of a copyright work? Is The Grey Album protected by the defence of fair use under copyright law because it provides a transformative use of copyright works? Can such remixes by compulsorily licensed? Does a 'mash-up' raise issues concerning the moral rights of attribution and integrity, which are recognised in Europe and Australia?


Contact radical ion-pairs of ammonium and fluoro-substituted ketones were generated in photochemical systems and their here-to-fore elusive esr spectra were characterized.


The structure and the task of electricity supply systems will dramatically change in the near future. Distribution systems are characterised by a large number of equipment and difficult access in urban and industrial environment. Therefore any modification has to be planned carefully and flexible solutions which are open for further improvement have to be selected. Based on the importance and the performance of electrical distribution systems the chances and the challenges for future distribution systems will be presented. Special emphasis is given on the new active components in distribution such as distributed generation and customers with smart meters. In addition to the standard components of electricity supply systems the need for communication and overlaying control systems is rising. As an example for an urban smart grid, the project "Masdar City" in Abu Dhabi is introduced. The main target to realize an example of the city of the future for 100'000 inhabitants, where all energy consumed is generated from renewable resources.


One of the modern alternatives for meeting the need for investment resources is crowdfunding. It is important for implementing small and medium-sized initiatives in the country. At the same time, this method of attracting funds in Islamic countries is limited by the complexity of integrating Islamic values with modern financial solutions. This study is devoted to analysing the features of the development of Equity-Based crowdfunding in Oman using the example of the Ethis platform as the only Islamic crowdfunding platform in the country. The methodological basis of the research is qualitative analysis methods based on the analysis of statistical data or quantitative indicators. A conceptual approach was used to analyse scholarly articles, research papers, and online sources related to Islamic Equity-Based crowdfunding. The Islamic Equity-Based crowdfunding platform Ethis was chosen as the subject of the study because it has a successful track record of achieving Shariah-compliant investment goals. Based on the results of the analysis of the functioning of the Islamic share crowdfunding platform in Oman, a conclusion about the importance of adopting the Capital Markets Authority's Decision No. E/153/2021 for developing the crowdfunding industry in Oman was made. The study theoretically proves the important role of CMA's certification in increasing the legitimacy of crowdfunding platforms and public trust in the Omani Equity-Based crowdfunding industry. At the same time, it was concluded that the existing legal restrictions on the expansion of the investor community serve as disincentives for the development of investing in crowdfunding among the general public. In addition, the small number of Equity-Based crowdfunding platforms in Oman is due to the difficulty of combining traditional Islamic values with modern financial technology. It actualises the need to develop a comprehensive approach to the harmonisation of Islamic traditions with the specifics of the development of digital financial technologies. The results of the study are essential for researchers, practitioners and other interested persons from the point of view of deepening the basic principles of crowdfunding development and promoting their implementation in the context of increasing profits from the use of crowdfunding platforms.

A study was made to determine the effect of coolant injection angularity on gaseous film-cooling effectiveness. In the correlation of experimental data an effective injection angle was defined by a vector summation of the coolant and mainstream gas flows. The cosine of this angle was used as a parameter to empirically develop a corrective term to qualify a correlating equation presented in Technical Note D-130 that was limited to tangential injection of the coolant. Data were also obtained for coolant injection through rows of holes normal to the test plate. The slot correlating equation was adapted to fit these data by the definition of an effective slot height. An additional corrective term was then determined to correlate these data.


Abstract Critical period of crop/weed competition was studied in upland rice during monsoon season from 1981 to 1983. Echinochloa colonum, Seirpus grossus, Dactyloctenlum aegyptium, Cyperus rotundus, C. iria and Trianthema monogyna were the major weed species. Competition from weeds during the first 15 days after sowing (d.a.s.) had no significant effect on the grain yield of rice. Competition beyond 15 d.a.s. caused drastic reduction in the grain yield. Grain yield of rice Increased significantly with the increase in the duration of weed‐free period up to 45 d.a.s. during two years. However, further increase in the weed‐free period up to 60 d.a.s. caused significant improvement in the grain yield of rice in only one year. Weeds emerging after 45 d.a.s. were lower in density and their growth was suppressed by the crop. Density of weeds emerging between 15 and 30 d.a.s. was high and could compete with the crop resulting in reduced grain yields. The period during 15 to 45 d.a.s. was found to be the most imp...


Because of the current image encryption algorithm based on the chaotic system exist the negative factor induced by the transient effect,and the pixel diffusion phase of theses algorithm was not using the whole random code sequence,resulting in the low security and not against each plain-and cipher-text attack. So the whole random code sequence and new Jacobian elliptic map were designed,as well as defining a S-box transformation rule; and constructing the pre-confusion-mixing-diffusion architecture,the image encryption algorithm based on the S-box transformation rule integration with Jacobian elliptic chaotic map was proposed to overcome above defects. Firstly, the S-box transformation rule was used to substitute and permute the pixel of original image; secondly,the external key was generated by the logistic map and algebra transformation function to iterate the Jacobian elliptic chaotic map to eliminate the transient effect,and ignore the results of the iteration; changing the external key,one group of pseudo-random sequence was got by iterating the Jacobian elliptic chaotic map again,and the new sequence was obtained by sequence correction function correcting the pseudo-random sequence to mixing the pixel of pre-confusion image under the condition of mixing mechanism; then the key stream mechanism was used to quantify the correcting sequence to obtain the one-dimension array to encrypt the pixel of mixing image under the condition of diffusion mechanism. This algorithm was test on the platform of MATLAB simulation software; the results show that the image encryption algorithm has a excellent encryption property such as highly secure,strong key sensitivity,the huge key space to against various kinds of attacks.


Nano-sized SiC reinforced B4C matrix composites were fabricated through a pyrolysis route from polycarbosilane(PCS) precursor. The microstructure and properties of the materials, compared with the materials sintered by direct mixed powders, were investigated. It shows that, the composites fabricated via precursor form a kind of complicated intra-intergranular structure: nano SiC within the grains of B4C and Al2O3, sharp angle-layered SiC precipitating in the grain boundaries, and SiC substructures within the grains of B4C. The crack deflection within the crystal grains is caused by intragranular fracture, increasing the fracture toughness significantly. The homogenization, relative density and mechanical properties of the composites fabricated by polycarbosilane precursor are higher than those of the composites made by directly mixed powders.

OBJECTIVE
To further evaluate the clinical usefulness of ondensetron(OND, supplied by Qilu Pharmaceutical Company) with modified regime in the prevention of cisplatin (DDP)-induced nausea and vomiting.

METHODS
A total of 773 patients were enrolled in a multicenter cooperative study. Of them, 330 patients were given i.v. OND 8 mg once or twice a day and 443 patients were given i.v. OND 8 mg plus dexamethasone(DXM) 10 mg once a day during the therapeutic period of DDP, followed by OND 4 mg orally twice a day for two days after DDP treatment.

RESULTS
Effective control of acute nausea was achieved in 86.7% and 94.8% of the patients receiving OND alone and OND plus DXM, respectively(P < 0.001). The mean frequency of vomiting was 0.9 times in OND and 0.4 times in OND plus DXM(P < 0.01). Total control of delayed vomiting (day 2-5) was comparable in both groups. Complete inhibition of vomiting (CR rate) was more frequently observed in males than in females. Adverse effects were identical and well tolerated.

CONCLUSION
OND with modified regimen is effective in the control of DDP-induced vomiting. It is more effective when OND and DXM are given than OND given alone.


The authors provide a brief review of the history and assessment of math anxiety, its relationship to personal and educational consequences, and its important impact on measures of performance. Overall, math anxiety causes an "affective drop," a decline in performance when math is performed under timed, high-stakes conditions, both in laboratory tests as well as in educational settings. This means that math achievement and proficiency scores for math-anxious individuals are underestimates of true ability. The primary cognitive impact of math anxiety is on working memory, particularly problematic given the important role working memory plays in math performance. The authors conclude with a discussion of risk factors for math anxiety and some factors to be kept in mind when working with math-anxious students.


Few references of maternal AIDS associated to Toxoplasma gondii infection exist in the literature, in spite of the fact that the newborns of HIV infected mothers are prone to infection. We present a case of a 23-year-old HIV positive mother with accentuated weight loss and Kaposi's sarcoma during pregnancy, having probably been infected by toxoplasma in the last trimester. The newborn showed early and progressive respiratory distress, disseminated petechiae and hepatosplenomegaly. He died eight days after birth. Morphological feto-placentary examination revealed acute, severe and disseminated toxoplasma lesions; noteworthy was the abundance of trophozoites and cysts of the protozoon. HIV p24 antigen was detected in the placentary tissues by immunohitochemistry.


The national focus on educational quality outcomes and student retention has led to a project on self-assessment of technology competency of entry-level students into the Waikato Institute of Technology. Personalisation of learning is a driver and it is intended the assessment tool will enable prospective students to gain an understanding of their own levels of technology competency. Reporting functionalities of the tool are intended to interface with existing student support processes with the aim of informing student retention strategies.


The energy yield of a solar panel can be severely impacted by partial shading. Shade caused by nearby static objects can hardly be avoided in installations such as building-applied or building-integrated photovoltaics. Smart reconfigurable photovoltaics (PV) panels are able to change their intra-module configuration to reduce this impact: small substrings can be rewired to be connected in a more optimal configuration. To achieve this, a reconfiguration switch needs to be designed. In this paper a switch for the optimization of module power by reconfiguration of all strings (SOMBRA), a smart switch, is presented. SOMBRA is a fully integrated, low-ohmic switch, designed for currents up to 10 A. It is fully floating up to 50 V, while still being able to communicate with a central unit as an inter-integrated circuit (I 2 C) slave. Two versions were realized, SOMBRA-LV10 for low voltages (LV) and a load current of 10 A, and SOMBRA-HV05 for high voltages (HV) and a load current of 5 A. Measurements proved these devices to be functional, measuring an on-resistance of 1.3 m Ω for SOMBRA-LV10 and 7.3 m Ω for SOMBRA-HV05. This paper will elaborate on the operation, design, and implementation of SOMRBA, as well as the first tests with a small reconfigurable PV module.


The pollution of fuel systems of diesel locomotives was comprehensively analyzed. Its sources and harm were pointed out. The current pollution situations of diesel locomotive fuel systems at home were decomposed. The necessity and importance of pollution control were emphasized. The reasonable methods and measures of pollution control were proposed.


A seismic simulation method for the bilinear system of base isolation building based on SIMULINK and STATEFLOW was proposed. The system response sensitivities to its basic parameters were analyzed. The relation spectra between system responses and system basic parameters were established. Research indicated that the dominated factors to system seismic response are the yield coefficient and the second period of the b/linear system, while the first period of the system is subordinative. The optimal yield coefficient of the system is correlative with earthquake level. The relation spectra present notably nonlinear. The system basic parameters have significant interaction in higher level.


The set-up and improvement of procedure law system mark the establishment of modern rule of law.In China,the modernization of the procedure law has a history of over one hundred years.It is originated from the legal transplantation carried out by the legal authority in the late Qing Dynasty.During the past one hundred years,the procedure law system underwent a checkered career.Lessons and experiences learned from reviewing this history can help improve China's current procedure law system and better reach the target of the Constitution——safeguarding human rights.


With the procedure described here, is it possible to restore the damaged dental hard tissue in a minimally invasive manner, satisfying the highest demands for form, color, and function. The disadvantages of conventional tooth-colored cervical filling materials are eliminated by using ceramic veneers. The durability of this treatment, using esthetic and conventional criteria, is certainly greater than that of conventional tooth-cervix filling materials.


The spectral properties of trivalent erbium ions (Er3+) are systematically studied in a melt-quenched germanate glass (60 GeO2-20PbO-10BaO-10K2O-0.1Ag2O) containing silver (Ag) particles. Thermal treatment of the material leads to the precipitation of Ag particles as observed by transmission electron microscopy and confirmed by absorption spectrum for the obvious surface plasmon resonance peak of Ag particles. The fluorescence from Er3+ in the 10-min-annealed sample with Ag particles is found to be 4.2 times enhanced compared with the unannealed sample excited by 488-nm Ar+ laser. A comparison is made between a spectral study performed on the unannealed Er3+-doped sample and the one annealed for 20 min. The data of absorption cross section and Judd—Ofelt intensity parameters show the agreement between the two samples no matter whether there are Ag particles, indicating that the introduction of Ag particles by post-heat treatment has no effect on the crystal field environment of Er3+ ions. The fluorescence enhancement is attributed to the surface plasmon oscillations of Ag particles in germanate glass.

The bed has the advantages of fast lifting and labor-saving operation. The medical lifting bed comprises walking wheels, a bed frame and a chassis, and two rockers are hinged between the bed frame and the chassis, forming a parallelogram hinged mechanism. The two rockers are respectively fixed with one sliding arm. One of the sliding arms is hinged with an ejector rod of a foot pedal oil pump with a both-way operation foot pedal. A casing of the foot pedal oil pump is hinged with the chassis. A connecting rod is hinged between the two sliding arms. The utility model has the advantages of smooth and fast lifting and labor-saving operation, bringing convenience for medical staff to treating, transferring and conveying a patient.


On April 30, 1994, Gregory Messenger was charged with manslaughter for physically disconnecting his premature son from a ventilator.1 He was acquitted of these charges on February 2, 1995. Although appellate courts have dealt with various aspects of withdrawing life-sustaining medical treatment (LSMT) in infants,2 State v Messenger raised the issues involved when this support is not desired by the parents at the time of birth. This case sets no precedent for future cases on this point. There is no appeal of a criminal case when the defendant prevails; therefore, for lawyers and judges it will remain just another trial court loss for a prosecutor.


Different aspects of long-term memory display different trajectories across the adult years. Both semantic memory and nondeclarative memory are relatively preserved. Episodic memory, however, is subject to age-related changes, becoming both less detailed and less accurate as adults age. Explanations of these changes have focused on broad underlying mechanisms as well as on more specific processes. The role of goals and priorities in deciding what information to remember or to include in narratives about personal experiences must also be considered.

Ibuprofen (IPB), α-methyl-4-(2-methylpropyl)benzene acetic acid, is one of the most common nonsteroidal anti-inflammatory drugs (NSAIDs). It is widely used as an analgesic in mild to moderate pain, and in the treatment of rheumatoid arthritis and osteoarthritis (Zhao et al., 2005). The conventional daily dose of this NSAID is 600–1200 mg per day (De Brabander et al., 2004). It was the 28th most dispensed drug in the USA in 2017 (Wong et al., 2021). The antimicrobial potency of Ibuprofen has been demonstrated in its ability to reverse resistance related to efflux pump activity (Ogundeji, 2016). All pharmaceutical forms are subject to chemical and microbiological quality control. A microbiological quality control method that will be used in routine for determination of product microbiological purity must be subject of validation. Microbiological quality control parameters for Ibuprofen film coated tablets 400mg as non-aqueous pharmaceutical preparation for oral use are: Total Aerobic Microbial Count (TAMC), Total Yeasts and Molds Count (TYMC) and Absence of Escherichia coli (Ph.Eur. 10.0, 2019).

We present a study of absorption line-profile variations in early-B type near-main-sequence stars without emission lines. We have surveyed a total of 171 bright stars using the Nordic Optical Telescope (NOTSA), William Herschel Telescope (ING) and Coudé Auxiliary Telescope (ESO). Our sample contains 75% of all O9.5−B2.5 III-V non-emission-line stars brighter than 5.5 mag. We obtained high signal-to-noise, high-resolution spectra of the SiIII λ4560 triplet – for 125 stars of our sample we obtained more than one spectrum – and examined these for pulsational-like line-profile variations and/or structure. We conclude that about half of our sample stars show evidence for line-profile variations (LPV). We find evidence for LPV in about 65% of our sample stars brighter than V = 5.5. For stars with rotational broadening V sin i ∼ 100 km s−1, we find evidence for LPV in about 75% of the cases. We argue that it is likely that these LPV are of pulsational origin, and that hence more than half of the solar-neighbourhood O9.5-B2.5 III−V stars is pulsating in modes that can be detected with high-resolution spectroscopy. We detected LPV in 64 stars previously unknown to be pulsators, and label these stars as new β Cep candidates. We conclude that there is no obvious difference in incidence of (pulsational) LPV for early-B type near-main-sequence stars in binaries or in OB associations, with respect to single field stars.


The effect of the insertion of nonmagnetic Cr planes on coercivities of thin Co films has been studied in Co/Cr multilayered films. The in‐plane coercivity Hc∥ can be as high as 1800 Oe and can be adjusted easily, ranging from 650 to 1800 Oe. The large Hc∥ is related to the Co(110) in‐plane orientation which is induced by a Cr(100) in‐plane‐oriented underlayer. In addition, it appears that a decreasing saturation magnetization Ms, a decreasing average structural coherence length D in the direction perpendicular to the film, and a narrowing distribution of D are correlated to the increasing in Hc∥. The effects of texture, Cr interlayers, D and its distribution, and the Cr underlayer on the magnetic properties are discussed.


Localization based on the RGBD-SLAM may fail and generate great mapping error when collected Kinect feature points of image data are rare or absent.To solve the problem,an improved localization algorithm was proposed based on the inenial sensor(IMU),the somatosensory sensor(Kinect)and the motion state of the robot itself.The comparison and fusion were done for attitudes,at the same time,the prediction model and the observation model were constructed using IMU measurement data and results of Kinect pose estimation for position respectively,the robot's movement and motion commands restrictions were taken as constraints to do the extended Kalman filter(extended Kalman filter,EKF)integration for robot localization and mapping.Experimental results show that the method can improve the localization accuracy of the robot and the effect of mapping based on the RGBD-SLAM algorithm.


Cognitive flexibility theory is a learning theory that enables teachers to promote the use of educational technologies in the learning process as well as allowing students to delve deeper into the complexities associated with the middle school curriculum. This learning theory has four basic tenets that dovetail into interdisciplinary teams, an organizational structure frequently found in middle schools. This article introduces the basic tenets of Spiro's cognitive flexibility theory, offers insight into how cognitive flexibility theory can be compatible with middle school interdisciplinary teams, presents examples of how various educational technologies can be used with this instructional method, and provides an application of a unit of Florida history that demonstrates cognitive flexibility theory for the middle school curriculum.


Industry 4.0 is estimated to have an economic potential of 267 billion euros for Germany. As a highly dynamic and innovative industry, electronics manufacturing is expected to contribute 23 billion euros. In order to realize this estimated potential, industry 4.0 technologies need to be implemented in concrete use cases providing value to electronics manufacturers. To better understand the current state of industry 4.0 use case adoption, we conduct expert interviews with eight electronics manufacturing companies from industrialized countries. With the results of the interviews, we aim to better understand, which industry 4.0 use cases provide the most value to electronics manufacturers and to what extent they are already implemented.


There is suffering, pain, death in the world. This is a fact that cannot be denied, but that troubles the human mind, which is not ready to accept such suffering, nor even to find room for it in the conception he has of the "Divine" and of the world. Suffering-which is evil--is and shall continue to be an incongruity, which is in contrast with the perfection of the "Divinity" and with his power of ruling the universe. God, the Summum Bonum (the Supreme Good), can by no means be called responsible for the suffering experienced in our daily life, neither could it be limited in its absolute Power by any other force acting in contrast with it. The problem is vital, and its solution essential, because man cannot stand a challenge which remains without an answer, nor can he suffer pain without an adequate explanation. The question, although acutely felt at all times and in all traditions, is especially alive in our days and it is one of the problems most passionately discussed nowadays. 1) What did the ancients think of it? What was their solution in their various traditions? This is the anguished question that modern man asks of his predecessors, trying to solve for himself-not only intellectually, but on the pratical side of life--the eternal challenge into which suffering compels him, today as never before.


Derek Phillips is an architect who has specialized in lighting and was one of the first people, at least in the UK, to practice as a lighting design specialist. His work spans from the early 1950s until the present with a number of design credits to his name. He is also a prolific author and speaker on the subject. This wide experience makes him eminently qualified to describe lighting design at the end of the twentieth century. There are many books on lighting but few really address lighting design as an extension to architecture; most consider the technology and calculation of task lighting without addressing the appearance of the environment. This book goes some way to redress that balance. The book is divided into two main parts. The first deals with the elements and process of lighting design and the second describes a wide range of lighting examples. In Part 1 the author develops a lighting design strategy including both daylight and electric light. He also describes the process of seeing and perception. This is not covered in great depth but probably sufficiently well for most students of design. It touches on visual performance and comfort but also on those things which, apparently JM Waldram described as those things which go 'beyond engineering'. Part 1 also covers daylighting from an historical perspective as well as touching on the possibilities including mention of some hi-tech solutions and the constraints of energy consumption, glare and other aspects of the environment. The remainder of Part 1 takes the reader through electric lighting tools and techniques. This includes a reasonable coverage of lamp types and lighting hardware. This is not a technical text book but it puts the equipment into context with the building which is well illustrated and for the design student it provides a good introduction and will help them to go on to more detailed texts. The second part of the book is its real strength. It is a series of twentieth century lighting case studies. There are 59 in total, ranging from domestic through to corporate interiors. It covers small and large interiors and a wide range of applications including churches, schools, hospitals and art galleries. Each case study is well illustrated with photographs, many in colour, as well as drawings and a short descriptive text. Each one provides the reader with a visual impression of the lit interior, some daylit, some electrically lit while others combine the two. It also provides an indication of what was intended and how it was achieved lthough, inevitably, there are gaps. Lighting design education has often concentrated on the science and technology of the subject without sufficient attention being paid to the appearance of lit interiors and the way lighting needs to integrate with the building. This book helps correct this deficiency by example and because of this, it will be a worthwhile addition to the lighting student and practicing designers' library.

Williams Syndrome (WS) is a genetic syndrome due to a deletion of the band 7q11.23 in chromosome 7. It can be described by deficits in cognitive areas such as visual-spatial integration and linguistic skills. This profile is also present in the Syndrome of Non-Verbal Learning Disabilities (SNVLD), that is, the Williams Phenotype Syndrome (WPS), which has not yet been described, but shares the same cognitive and phenotype characteristics of WS. These similarities can support the idea that the band 7q11.23 of the chromosome 7 has more to do with pragmatic disturbances and less with formal aspects. I claim that my data can help to give a functional identification of the genes involved in cognitive processes located in the chromosomical band 7q11.23, deleted in WS.

Department of Applied Mathematics, University of Western Ontario, London, Ontario N6A 5B7, Canada(February 1, 2008)A large-scale molecular dynamics simulation is performed on a glass-forming Lennard-Jones mixtureto determine the nature of dynamical heterogeneities which arise in this model fragile liquid. Weobserve that the most mobile particles exhibit a cooperative motion in the form of string-like paths("strings") whose mean length and radius of gyration increase as the liquid is cooled. The lengthdistribution of the strings is found to be similar to that expected for the equilibrium polymerizationof linear polymer chains.PACS numbers: 02.70.Ns, 61.20.Lc, 61.43.Fs


In many industries, competition has shifted towards a technological timing competition. This also applies to new manufacturing-related technologies, which allow for the producing of superior products with lower costs. In particular, the field of new manufacturing technologies is very broad and new technological developments in this field can originate from competitors, research facilities, or universities in research fields that are not related at all to the originating company. Therefore, companies need a sophisticated technology intelligence system to remain competitive in the timing competition of manufacturing technologies. Our study analyses the state of development of technology intelligence systems in different companies in the context of their timing strategy for the implementation of new manufacturing-related technologies. The results show that pioneer companies have a more sophisticated technology intelligence system compared to follower companies. These pioneer companies more often follow a structured technology intelligence process, use more sources of information and apply different methods to evaluate the information. Furthermore, pioneers more often cooperate in their technology intelligence activities with external partners, in particular with customers, suppliers, and universities or research facilities.


Pattern calculus treats all computation as pattern matching, which is, in turn, central to the implementation of programming languages. Hence, its realisation in the general purpose language bondi provides a natural host in which to develop domain-specific languages (DSLs). bondi is a strongly typed language that supports mixing of programming styles to support the features required for language implementation. In particular, bondi supports queries, views and transformations that can be used to develop object-oriented meta-models. The approach is illustrated by growing a small combinatory language in which each language feature i.e. each production of each grammar, is isolated within a single object-oriented class that captures the rules for parsing, type inference, evaluation and printing. Further, growth is used to support lambda-abstractions, providing good evidence that this combinatory language could grow to support a general purpose programming language.


actual death, views of the deceased .and of the mourners are contrasted in-powerful, evocative images.

Readers may experience unexpectedly strong reactions to this grouping. Bertman summarizes the chapter beautifully,


Decision of how many and which embryos to transfer in each cycle is determined by multiple factors, and the integration of patient-specific considerations is challenging.

 We developed an embryo transfer strategy support tool (ET-SST) that finds the optimal way to conduct the embryo transfer process.

 In each transfer cycle, a decision of how many and which embryos to transfer is determined, based on embryo quality, risk of multiple pregnancies, maternal prognosis, cryopreservation factor, and the cost of each cycle. The parameters can be conflicting, high maternal receptivity might encourage single embryo transfer (SET) yet poor embryo quality might encourage multiple embryos transfer (MET) while co-considering cryopreservation, clinical risks, and future possible transfer. Current guidelines are not case-specific and only dictate a limit on the number of embryos to transfer based on maternal age solely, without regarding the heterogeneity of patients and several transfer cycles.

 We created a computational model integrating multiple parameters, assigning a specific embryo transfer option a value, based on the expected pregnancy rate. Assuming a given number of transferable embryos in a cycle, we calculate the expected value of a series of transfers (a strategy), using a recurrence relation. We applied dynamic programing that efficiently identifies the optimal strategy for the given cycle while considering maternal and other clinical parameters incorporated into the equation.

 The number of possible strategies is exponential with the number of embryos. There are 70 strategies with only four embryos viable to transfer, and the number increases to 4,550 with six embryos and over 100,000 with eight embryos. We created a recursive relation that describes the value of each strategy. Evaluating the different strategies is challenging even for modern computers. We apply dynamic programming to efficiently solve the recursion relation and identify the optimal strategy.

 To assess the optimal transfer strategies, we developed the ET-SST and generated an online web application (https://etsst.researchsoftwarehosting.org/). For a given set of oocyte retrieval embryos, the ET-SST calculates all possible multistep embryo transfer strategies and, using the value function, finds the optimal strategy based on embryonic, maternal, and clinical user-input factors. (1) Embryo quality scores (using any method of choice). (2) Maternal prognosis score (endometrial receptivity, maternal age). (3) Multiple pregnancy score. (4) Cryopreservation factor (estimating the effects of embryo freeze-thaw procedure). (5) Transfer cycle cost. Each factor receives a value between 0 (non-favorable) and 1 (favorable). Based on these parameters, the ET-SST defines the optimal strategy that maximizes the value function. To avoid limitations on the assessment of the embryos' developmental potential and the patients' clinical prognosis, the ET-SST allows using all tools of choice for the user-input assignment.

 This newly developed computerized model was not yet tested in a randomized trial.

 Here we showed an algorithm that generates a case-specific strategy that can incorporate the clinical parameters that can be evaluated by any method that is preferred by the clinician. The modern evidence-based IVF clinic should include not only evidence-based clinical parameters but also algorithm-guided personalized decision making.

The effect of clipping in the signal channel of a time averaging processor is investigated. It is shown that signal extraction is possible even tinder heavy clipping conditions. The analysis deals with signal extraction from noise-like and signal-like interferences.


A chip monopole antenna with a parasitic patch is proposed for GPS applications. To reduce the dimensions of the antenna, the chip monopole antenna is composed of stacked meander, helix structures, and a parasitic patch. The impedance and radiation characteristics of the antenna are investigated. The measured results show that the proposed antenna, having compact dimensions of 3.6 × 5 × 1.3 mm, has a bandwidth of 60 MHz (1.53–1.59 GHz) and a maximum radiation gain of 0.53 dBi.

In this paper, we demonstrated a resonator-based MEMS architecture for multi-sensor SOC applications. A newly developed 0.18  ${\mu }\text{m}$  1P6M CMOS ASIC/MEMS process was adopted to integrate MEMS sensor and circuits monolithically. By using resonators as the building blocks, multiple MEMS sensors including environmental temperature sensor, ambient pressure sensor, accelerometer as well as gyro sensor can be monolithically implemented with the readout circuits by the single standard ASIC/MEMS process without off-fab pre/post processes. The proposed architecture enables compact and innovative sentient-assisted SOC design for the emerging IOT applications.


Mitoura thornei, Thorne's hairstreak butterfly, is endemic to a single mountain in south-western North America. The extremely small geographic range of this species coupled with threats to its host plant, Hesperocyparis forbesii, motivated a study of habitat association and fine-scale mapping of both butterfly and host distributions. Often the study of habitat associations for rare or threatened species is complicated by habitat loss. In the case of M. thornei, the range is naturally small, which provides an opportunity to investigate small scale variation in vegetation and geographic features as they may affect larval and adult butterflies. Specifically, the following questions were posed: How much of the range of the host plant is occupied by M. thornei within the focal geographic area? What biotic and abiotic features predict the presence and abundance of M. thornei? How does tree age affect larval performance? These questions were addressed with a combination of field observations and laboratory experiments involving caterpillars. H. forbesii size (diameter at breast height) was found to have a significant association with the presence and absence of larval M. thornei, while slope, density of herbaceous plants and density of H. forbesii were found to be the factors most strongly associated with adult M. thornei. Laboratory experiments with larvae showed no effect of tree age on larval survival, but a slight reduction in adult size for individuals reared on foliage from the oldest trees. From a conservation perspective, the most important result is the widespread occurrence (greater than previously reported) of M. thornei throughout the study area. However, I caution that spatial factors (such as fragmentation, isolation and perimeter to


Abstract To complete our studies concerning collisional line broadening in the fundamental bands of SO2, hydrogen-broadening coefficients for 21 lines from the ν3band between 1341 and 1357 cm−1with 8 ≤J″ ≤ 33, 1 ≤Ka″≤ 16, helium-broadening coefficients for 3 lines from the ν1band around 1121 cm−1with 8 ≤J″ ≤ 36, 7 ≤Ka″≤ 9, and xenon-broadening coefficients for 6 lines from the ν3band between 1321 and 1366 cm−1with 4 ≤J″ ≤ 61, 0 ≤Ka″≤ 6 and 15 lines from the ν1band between 1072 and 1140 cm−1were measured at room temperature applying a high-resolution lead-salt diode laser spectrometer. For collisions with noble gases the temperature dependence in the range between 252 and 362 K was studied for three lines from the ν3band. For the same temperature interval the air-broadening coefficients of seven lines from the ν3band were determined. The hydrogen-broadening coefficients are larger than those previously published for air broadening, but show the same quantum number dependence. A weak maximum in theKa″dependence and no trend in theJ″ dependence are observable. In contrast to this and to the well-studied quantum number dependence of the self-broadening coefficients a more pronouncedJ″ dependence but no significantKa″dependence was measured in the case of collisions with noble gas perturbers. Temperature exponents of 0.72 ≤n≤ 0.99 (average value 0.83) for the air-broadening coefficients were observed. The smaller exponent of about 0.7 determined for noble gas collisions is in good agreement with theory. Due to the large uncertainties for thenvalues caused by the restricted temperature range a perturber dependence can only be supposed. Nevertheless, the data are close to the theoretical prediction.

This study defines the silver portal as a specialized internet portal that will be probably popular with the pre-senior/senior internet users who are over 40, sooner or later. The purpose of the study is to analyze what types of online contents on the silver portal are mostly preferred by the pre-senior/senior, and does the preference of those content types vary according to the demographic and the internet usage characteristics of the pre-senior. The study also is to suggest some research propositions, based on the analysis results, that could be applied to empirical studies in the future which deal with various research questions on the silver portal. To accomplish these research purposes, the study performed a survey for the prospective silver portal users who are living in the areas of Seoul and Kyeonggi, South Korea, and did various statistical analyses. This study found that the preference of content types of the silver portal vary according to some personal characteristics of the prospective silver portal users, and moreover proposed a few of research propositions on the relationships between personal characteristics and preferred content types.


Simple Summary The black soldier fly (BSF) is a saprophagous insect that has been applied to organic waste management while providing high-quality insect protein. Flocculants are widely present in organic wastes that could be treated by black soldier fly larvae (BSFL), such as food wastes, municipal sludge, and cyanobacteria sludge. This study investigated the effect of flocculants on bioconversion of BSFL. The results showed that the addition of flocculant affected the bioconversion efficiency and nutritional composition of BSFL. The relative abundance of bacterial genera related to lipid metabolism decreased with increasing flocculant concentrations while disease-related taxa increased in relative abundance. This study could serve as a reference for related research and applications in the future. Abstract Black soldier fly is a saprophagous insect that has been widely reported in recent years due to its excellent performance in bioremediation. Due to the widespread presence of flocculants in the organic waste treated by black soldier fly larvae, this study aimed to evaluate the potential impacts and risks of flocculant addition (a combination of poly aluminum chloride and polyacrylamide with the ratio of 50:1). Results showed that the growth and weight of BSFL in the high-exposure groups (≥200 mg/L) were inhibited. The bioaccumulation of aluminum (Al) in larvae was estimated, and the proportions of different Al forms in the frass from high to low were the residual state (41.38% to 67.92%), water-soluble state (16.88% to 37.03%), acid-soluble state (8.45% to 18.72%), and alkali-soluble state (3.38% to 5.14%). The relative abundance of bacterial genera related to lipid metabolism decreased with increasing flocculant concentrations while disease-related taxa increased in relative abundance. The results serve as a reference for subsequent research and application of the treatment of flocculant-contaminated waste by BSFL.


As science and culture go global, accompanying a global economy, tensions ravage small communities nearly everywhere for basic needs such as food, shelter and health are frequently not met and prosperity is unevenly distributed. The paper addresses one of those basic human needs and rights — health — focusing alternative medicinal practises and predominantly medicinal herbs production, trade and consumption in Latin America, seen as a fair usage of local plant resources by local actors, under ancestral Indian healing traditions aimed at lower income urban households. Research undertaken in four cities, different in size (2 up to 17 millions) and location (North and South America) has shown there are market niches for alternative medicinal trade, income generation at small scale being a fact, and medicinal agricultural ecosystems being sustainable either in rural, periurban, even urban environments. Herbs, fruits, roots, etc. consumed and traded in urban markets come from diverse locations ranging from rainforests to mountainous milieus: 1. Lower and upper Amazonia (Brazil and Peru); 2. Plateaus and Andean high plateaus (Peru and Chile); 3. Forested volcano slopes (Mexico, Peru and Chile); 4. Peri-urban valleys (Chile) and season flooded planes (Brazil). Some plant species are wild and collected under demand, but most of them are grown in peri-urban and rural areas, using less than one-hectare plots and no chemicals at all. Medicinal herbs trade field researched in Lima (Peru), Santiago (Chile), Belen (Brazil) and Mexico City (Mexico), depicts a sustainable use of local and national natural and agricultural resources, whereas targeting lower income populations, contributing to decrease health risks and therefore addressing the issue of poverty in a globalised world. 2 Background and Methods Portuguese Tropical Institute research project named Noah's ark has been devised as far back as 1998 even though it has been baptised only in 2004. It includes extensive sample research over natural pharmacy conducted by the author together with universities and scientific organizations from 4 countries and big cities: Goeldi Museum at Belen (Brazil); University of Chile, Santiago (Chile); Catholic University, Lima (Peru); and UNAM, Mexico City (Mexico). Survey extracted from Belen's home gardens, a city located in lower Brazilian Amazon, came first. The query was part of an urban and peri-urban agriculture investigation, and the main objective was to promote food sufficiency in a quite remote and deprived regional metropolis using vacant plots, front-and backyards (MADALENO, 2000). Surprisingly medicinal herbs recorded during fieldwork (555 inquiries and several interviews) were so abundant that they came second as crops in home gardens and peri-urban plots (following fruit culture). Additionally domestic herbal remedies collection was quite prolific, particularly among females interviewed, and very especially the elderly. The catalogue of prescriptions involved ancestral Amazon traditions, European herbal remedies and African medicines for nearly any possible body affection or affliction one might imagine. During 2002-2003 a joint Portuguese-Chilean team continued the trend in Santiago, uplifting the quantity and quality of plant species registered as being commonly consumed in South America, as enriching a directory of herbal medicines, with particular emphasis on the ones based in Indian healing traditions. Plant therapists, healers, medical doctors and machis (shamans) turned out to be the best sources of information driving us to the conclusion that the main herb, roots, fruit, tubers providers were urban markets and not the farmed plots. The next step was to redirect fieldwork and interviewing process, in order to select the most representative urban centres in Latin America, aiming tropical environments but also large metropolis and fairly representative indigenous cultures. Mexico City and Lima were the targeted locales having been sample researched between 2004 and 2006. Aztec, Nahua, Zapotec (Mexico), Quechua and Aymara healing traditions (Peru) have been added to Brazilian Amazon Indian prescriptions and Mapuche herbal remedies (Chile). About 1,000 medicinal plant cultivation, trade surveys and healing agent interviews have been extracted from the four selected Latin American Metropolis. Above 300 different plant species have been recorded together with a huge range of ethno-medicinal uses. 3 Research Results Results have shown that people are aware of natural pharmacy limitations in serious sicknesses, even the ones possessing quite low educational level. That's because vaccination campaigns, national healthcare systems are adamant. Of course the option for natural medicines and therapies is in most instances a choice, not a necessity. However, herbal remedies and ancient Indian, European and al. prescriptions target principally lower income groups and Indigenous peoples. Impressive level of medicinal plant consumption was recorded in Mexico City, the only selected metropolis that possesses a central market solely for herbal remedies trade. Sonora, is an enormous bazaar offering two categories of traders: 1. Informal merchants, mostly females, are settled around the market; they usually are microfarmers either. Two up three times a week, they travel to the Federal District from pueblos located in neighbouring Puebla, Morelos and Mexico states, in order to sell their fresh produce, from 5 to 10 o'clock a. m. After that time, they are obliged to abandon the trade sites, loyalties between "informales" and a quite severe (outlaw and repressive) solidarity chain system obliging them to either sell the remainder to the established retailers inside the market or then travel further to La Merced or Jamaica markets, leaving the ground to informal faster return dealers (clothing, shoes, etc.), the ones who can afford to oversleep and start working later in the morning, allowed to trade at better times for regular urban costumers. According to Mexican statistics only 3 in 10 women are formally employed in Mexico City. The remainder are housewives, service providers and street traders. The informal retailers earn about 1 US dollar per hour and amount to 31.8% of active residents (INEGI, 2003). 2. Formal traders work inside Sonora every single day of the week, without exception, which is a common fact in all formal market businesses all over Latin America. The vast majority trades dried plant parts and a good range of Indian prescriptions under demand. Not less imposing was medicinal plant consumption recorded in Belen, particularly old family and domestic remedies. Brazilian Amazon is by far the most biodiverse of all milieus explored, having registered the most uncommon plant species and usages, whose pharmacological activities are among the least lab researched. As to the capital city of Peru, it is one of the most prolific both in terms of dried and fresh species offer and ancestral healing traditions. Santiago top ranks a country that widely ignores ethnicity, even though the metropolis stages a chain of Indigenous Herbal Pharmacies (Farmacia Herbolaria Mapuche) uncommon elsewhere in Latin America. The table depicts ethno-medicinal uses of the most consumed plant species in the 4 selected urban centres: 1. Fake Lemmon Balm (Toronjil) is top ranking in Mexico City; 2. Chamomile (Manzanilla) is the first option in Lima; 3. Lemmon Balm (Melisa), imported from Europe is preferred in Santiago; 4. Lippia alba (ErvaCidreira) the most consumed in Belen. The surprising conclusion is that everybody looks for the same remedy: a reliable infusion for pains (analgesic), a digestive tea ready for use after heavy meals, and a mild sedative that can help to cope with stress, an urban affliction worldwide. The common name is sometimes the same, however nomenclature reveals family, gender and species aren't. Not surprisingly in Mexico and Brazil, where faith in herbal remedies remains unshaken by globalisation, the preferred plant species are endemic, but in biased Peru and Chile the favoured herbs are European and largely recommended by conventional medicine (MADALENO, 2006).

The present project aims to reinterpret the Centenera 2 well logs, being focused mainly in the improvement of the interpretation of porosities and other characteristics present in the formations. In order to complete this objective, it has been developed a methodology that could be applicable to similar studies, especially when old well logs are studied. The methodology begins with a process that consists on transforming the original paper well logs into digital format well logs, so they can be treated by computer. Then, the digitized well logs are corrected for well effects (temperature, diameter, mud density, etc.). Later, a general interpretation of the well is made, subdividing it in several zones geologically different, for this way to choose more economic interest zones. Finally a quantitative interpretation of the formations is carried out, determining their porosities through different methods. The data obtained by the methodology, demonstrated the existence of formations potentially producers of gas, the same ones that have bigger porosities to those described by studies in past decades.


Marxist theories of history have long been an important research area in Marxism studies abroad.It is the Marxist school of history.Major research topics of this school are all closely related to Marxist historical materialsim.However,Chinese scholars,especially researchers who study Marxism abroad,have long neglected researches abroad on Marxist theories of history.They are not clear about findings on Marxist theories of history from the perspective of history of thoughts.The paper then offers a review of recent studies of foreign scholars in this area.It is meant to promote understanding of Chinese scholars about the current situation of researches abroad on Marxist theories of history,and provide them with access to thoughts in studies of historical materialism.


In this paper we present the modelling and analysis process of the photovoltaic (PV) tracking mechanisms as multibody systems (MBS). The general steps for the MBS modelling are presented, along with the conditions in which the kinematic elements (parts) can be modelled as bodies (with mass & inertia properties) or composite restrictions. The modelling as multibody system is important, because on it depend on the complexity of the theoretical model, by decreasing the number of moving bodies, and consequently the number of unknown generalized coordinates. The application is made for the azimuthal tracking system of a PV platform. The dynamic model of the solar tracker is developed by using the MBS ADAMS software package.


Distribution three-phase four wire power systems are undergoing significant evolutions in physical and technical features as a result of the large-scale integration of rooftop solar photovoltaics. For such multi-converter power systems, the occurred oscillation issues usually involve a variety of components. In addition, the intertwined relationship between dual frequency coupling effect and sequence components coupling effect complicates the analysis processes and makes the existing analysis results not suitable. To analyze the oscillation characteristics accurately of such system, this paper proposes a quantitative analysis method of oscillation mode based on the admittance network model, which considers dual frequency coupling effect, sequence components coupling effect and their intertwined relationship. In addition, a method to calculate the accurate characteristic roots effectively and flexibly based on a partitioned interval ant colony algorithm is also proposed. Finally, the node oscillation participation factor and oscillation mode sensitivity are defined to reveal the oscillation characteristics and laws of the three-phase four-wire grid-connected systems. The time-domain simulations results implemented in MATLAB/Simulink validate the analytical results.
