Extended Abstract Antibiotic resistance has been becoming a global problem threatening modern medicine. Thorough studies on this phenomenon have uncovered the crucial role of the environment in the development and the dissemination of this trait among bacteria. Wastewater treatment plants have been recognised as hotspots for antibiotic-reistant bacteria and antibiotic resistance genes [1]. Moreover, it has been suggested that the specific conditions within wastewater treatment plants such as sublethal concentrations of antibiotics and high microbial density favour horizontal transfer of resistance genes [2]. However, little do we know about the fate of antibiotic resistance determinants and antibiotic-resistant bacteria in treated sewage receiving water bodies. The already available results range from small effect to a significant impact depending on screened genes/bacteria and different water ecosystems [3], [4]. Hence more studies are needed to clarify which genes are more persistent in given environments. The aim of the study was to track the fate of β-lactam-resistant bacteria and β-lactam resistance plasmids within a wastewater treatment plant during the treatment process and in a final effluent receiving environment. For this purpose samples of raw sewage, activated sludge, final effluent, Żywieckie Lake water and sediment were collected. Water and sediment samples from the Sola River upstream the lake were also included to the analysis as control. The number of ampicillin-resistant and total culturable heterotrophic bacteria was determined using LB-agar or ampicillin-amended LBagar plates, respectively. Ampicillin resistance plasmids were isolated by exogenous method and subsequently transformed to E. coli cells for further analysis. The study revealed that even though the treatment process notably decreases the number of resistant bacteria (a 100 fold decrease when compared to raw sewage), they are still released in significant amounts (103CFU/ml of treated sewage). On the other hand, the results obtained from the Sola River uncovered the existence of considerable resistome in this environment suggesting that it may be impacted by other sources of antibiotic-resistant bacteria such as illegal untreated sewage dumping from private households. An ampicillin resistance plasmid library in E. coli cells was set and the replicons were characterised. The research is supported by National Science Centre grant 2014/13/N/NZ9/03915. KB had been receiving a scholarship provided by the "DoktoRIS — Scholarship programme for innovative Silesia", which was co-financed by the European Union under the European Social Fund covered by Human Capital Programme.


Comadia redtenbacheri (Hammerschmidt, 1847) is an insect highly regarded for its commercial and nutritional value. Adult fluctuation in a plantation of Agave salmiana Otto ex Salm-Dyck was determined using ultraviolet light traps. Trapped adults were counted weekly during three periods (December 2013 to December 2014, December 2014 to December 2015, and December 2015 to June 2016), and temperature and relative humidity were recorded. Adult population was present 157 days on average, from December to May, with peak capture on day 83. The average sex ratio of females to males was 1:14. Average environmental conditions that favoured the highest capture in the three periods were 17.8º C and 47.1% relative humidity. Knowledge of the period of adult presence and the influence of temperature and relative humidity are important for management and conservation of the insect population by farmers and gatherers.


Background— The mammalian target of rapamycin (mTOR) functions within the PI3K/Akt signaling pathway as a critical modulator of cell survival. On the basis of promising pre-clinical data, the safety and tolerability of therapy with the mTOR inhibitor RAD001 in combination with radiation (RT) and temozolomide (TMZ) was evaluated in this Phase I study. Methods— All patients received weekly oral RAD001 in combination with standard chemoradiotherapy, followed by RAD001 in combination with standard adjuvant temozolomide. RAD001 was dose escalated in cohorts of 6 patients. DLTs were defined during RAD001 combination therapy with TMZ/RT. Results— Eighteen patients were enrolled with a median follow-up of 8.4 months. Combined therapy was well tolerated at all dose levels with 1 patient on each dose level experiencing a DLT: Grade 3 fatigue, Grade 4 hematologic toxicity, and Grade 4 liver dysfunction. Throughout therapy, there were no Grade 5 events, 3 patients experienced Grade 4 toxicities and 6 patients had Grade 3 toxicities attributable to treatment. On the basis of these results, the recommended Phase II dose currently being tested is RAD001 70 mg/week in combination with standard chemo-radiotherapy. FDG PET scans also were obtained at


Effect of supplement Ultraviolet-B(UV-B) radiation during different growth stages on yield potential and protein content were investigated by using Sasanishiki ( O.sativa L. subsp. japonica ), an UV-resistant cultivar from Japan as material. Differences in yield and yield components were not significant between the control and the UV-B treatments during the vegetative stage (from transplanting to panicle forming), reproductive stage (from panicle forming to heading) and flowering-ripening stage (from heading to ripening). It was found that the percentage of higher thick-sized brown rice tended to decrease due to UV-B radiation. The content of total N and protein in brown rice increased by supplement UV-B radiation during flowering-ripening stage. Among the components of protein, only the content of glutelin was increased significantly by UV-B treatment.


Occludin is one of the best characterized protein in tight junction associated proteins,it seals paracellular way to form the basic structure of tight junction.It performs major functions including fence function and paracellular barrier function.Downregulation of occludin protein might induce the disruption of pulmonary epithelial barrier,blood-brain barrier,intestinal epithelium barrier,blood-testis barrier,which has been proved to be associated with the cause and progress of many diseases.Therefore,the regulation mechanism and clinical significance of occludin protein have been the focus at home and abroad.

Key words:
Occludin protein; Tight junction; Barrier function; Regulation mechanism


Complete composition-tuned CdSxSe1−x alloy layers (avg. thickness = 50 nm) were deposited on pre-grown TiO2 nanowires by the thermal vapor transport of CdS/CdSe powders, producing core–shell nanocable arrays. CdSxSe1−x alloy nanowires were also synthesized with full composition tuning by the same method for comparison. The CdSSe nanowires consisted of Se-rich and S-rich pseudo binary phases, while the nanocable shell consisted of more complex multinary phases including CdSe and CdS. Remarkably, unique CdS–CdSSe–CdSe multishell structures were produced in the Se-rich composition range. The photoelectrochemical (PEC) cells fabricated using the as-grown nanocable arrays show higher solar photocurrents and hydrogen generation rates for the Se-rich shelled TiO2 nanocable arrays. This suggests that the CdS–CdSSe–CdSe multishell structures increase greatly the PEC performance by producing novel band alignment for efficient electron–hole separation following enhanced visible-range photon absorption.


We investigated the effect of hydrogen on the tensile properties of a quench-tempered low-alloy steel, SCM435, with the tensile strength of 930 MPa used for hydrogen storage cylinders. Tensile specimens were machined from a cylinder with the inside and outside diameters of 245 and 315 mm. The specimens were immersed in a 20 mass% aqueous solution of ammonium thiocyanate (NH4SCN) at 313 K for 48 hours and then charged with hydrogen. Tensile tests were performed in the air at room temperature. The cross head speed was ranged from 0.01 to 100 mm/min. Hydrogen-charged specimens were hold in the air for a period of 1 and 300 hours. The 0.2% proof stress and tensile strength for the hydrogen-charged specimens were similar to those for the uncharged specimens, whereas the reduction of area was lower in the hydrogen-charged specimens than in the uncharged specimens. Thermal desorption spectroscopy showed that the residual hydrogen contents in the hydrogen-charged specimens fractured by tensile tests were between 0.14 and 0.93 mass ppm. The reduction of area of the hydrogen-charged specimens decreased linearly with increasing residual hydrogen content. Scanning electron microscopy showed that the cup-corn fracture occurred in the hydrogen-charged and the uncharged specimens and that the fracture surfaces were covered with dimples. The normal stress fracture area in the center of the hydrogen-charged and uncharged specimens was almost the same. The shear stress fracture area near the specimen surface was wider in the hydrogen-charged specimens than in the uncharged specimens. This means that hydrogen enhances slip deformation near the specimen surface and resulted in the lower reduction of area in the hydrogen-charged specimen. We therefore concluded that the hydrogen embrittlement behavior of the 900-MPa-class SCM435 steel was explained by the hydrogen enhanced localized plasticity model rather than by the lattice decohesion model.


The area configuration of different functional spaces has an important impact on the preliminary planning of large general hospitals. This paper takes a 2000-bed hospital in Zhejiang Province as an example to introduce the area configuration of hospital's functional space in detail, including the main functional rooms on the ground and the underground buildings, and the area configuration is analyzed. The results show that the average construction area of hospital beds is 191 square meters, and the total area of buildings for seven facilities, underground garage, medical research rooms and rooms for medical equipment accounts for 92.4%. In the decision-making stage of hospital construction, the area configuration of these four functional spaces should be focused to meet the needs of the hospital's operation and development.


The present study characterizes apricot germplasm through the use of RAPD markers. Twelve apricot cultivars ('Chuli', 'Suffaida', 'Shakarpara', 'Kaisha', 'Nari', 'Royal', 'Charmagaz', 'Shipley Early', 'New Castle', 'Tilton', 'Turkey' and 'Moorpork') were selected. RAPD analysis was carried out using 18 random decamer primers, 16 of which showed polymorphism. A total of 79 bands were amplified, out of which 56 were polymorphic and 10 were specific RAPD markers. Total polymorphism was 70.89%. The similarity value ranged from 0.59 to 0.86. A low similarity value was obtained between 'Shakarpara' and 'Chuli' cultivars and high between 'Moorpork' and 'Suffaida' cultivars. On the basis of a similarity matrix, a dendrogram was constructed by the UPGMA method. RAPD analysis is useful in a certification scheme for releasing certified plant material. It could also be useful for assessing genetic variation among different apricot accessions. _____________________________________________________________________________________________________________


ABSTRACT DTCS (Dutos e Terminais do Centro Oeste e Sao Paulo), an operational organ of PETROBRAS, is the organization responsible for the operation of a 2300-km-long pipeline system for the transportation of crude oil and hydrocarbons. Such a system, which is continually growing, has a representative history of leakage occurrences, particularly in its first years of operation. Based on a statistical analysis of these occurrences in the pipeline system, the number of leakages was reduced in the last few years through actions taken to minimize them. Criteria were established to define the proper moment for inspecting the pipelines with corrosion pigs, and other priority actions were also developed to reduce leakage occurrences. The data pertaining to occasional new leakage occurrences are analyzed every 6 months, and a report is issued proposing new actions or ratifying the existing ones.

CONCLUSION
Among different lasers, Er:YAG laser can be used as an alternative technique for surface treatment of indirect composites.


Objective To describe the Chinese children's blood lead levels(BLLs) and identify its trends of changes after leaded gasoline was banned in China.Methods Articles on children BLLs published from 1994 to 2008 were collected through Chinese Biomedical Disk,Chinese Journal Full-Test Database and other ways.Finally 93 articles,including 27 of rural children were eligible according to the following criteria:(1)BLLs measured by graphite furnace atomic absorption spectroscopy or inductively coupled plasma-mass spectrometry,(2)strict quality control,(3)sample size more than 100,(4)children aged from 0 to 14 years old,(5)no lead pollution sources in the areas where the screened subjects live.A total of 19 eligible articles of children's BLLs in industrial areas were selected based on the 1st-4th criteria above.Then all selected articles were divided into four categories according to the time of sampling: sampling prior to the year when the leaded gasoline was banned as "before ban";the year prior to 2002 after the ban as "the first segment after ban";2003—2005 as "the second segment after ban" and 2006—2008 as "the third segment after ban".Results The mean BLLs of Chinese children were 98.21 μg/L before ban,85.02 μg/L,83.63 μg/L,61.82 μg/L in the first,second and third segment after ban,respectively.The prevalence rates of BLLs≥100 μg/L were 37.34% before ban,27.68%,25.97%,10.90% in the first,second and third segment after ban, respectively.For rural children,the mean BLLs were 87.53 μg/L before ban,72.23 μg/L after ban;the prevalence rates of BLLs≥100 μg/L were 28.40% before ban,17.85% after ban.For children in industrial areas,the means of BLLs were 110.76 μg/L before ban and 106.77 μg/L after ban.Conclusion BLLs of children decreased significantly after the ban of leaded gasoline in urban and rural areas of China while those of in industrial area showed little decrease;BLLs of Chinese children are still much higher compared with those in developed countries.


In recent years,constructive field techniques and the method of renormalization group around extended singularities have been applied to the weak coupling regime of the Anderson Model. It has allowed to clarify the relationship between this model and the theory of random matrices. We review this situation and the current program to analyze in detail the density of states and Green's functions of this model using the supersymmetric formalism.


On February 4,2008, shortly before Kosovo's controversial unilateral secession from Serbia on February 17 of that year, the Council of the European Union (EU) adopted a Joint Action creating the European Union Rule of Law Mission in Kosovo/EULEX (hereinafter EULEX), the largest and most important mission thus far undertaken within the common European foreign and defense policy. Although EULEX is first and foremost a European undertaking, it is also strongly backed by the United States, which agreed to shoulder 25 percent of the operating costs while the remaining costs would be shared by European and other states. In October 2008, the U.S. Department of State further agreed to provide EULEX with eighty police officers and up to eight judges and prosecutors.

Although it is generally believed that the secondary alteration phases observed in CM chondrites resulted from parent body reactions, the influence of nebular processing can not yet be dismissed. We have analyzed 5 CM falls using optical and electron microscopy to construct a comprehensive pictorial reference set of textural and mineralogical associations bearing on the origin of alteration products in these meteorites. Our analyses support pervasive aqueous alteration on the CM parent body, but they do not exclude the possibility of minor nebular alteration.

ABSTRACT We study the limiting behavior of the Kuramoto–Sivashinsky/Korteweg-de Vries (KS/KdV) equation We show that in the appropriate sense, the solutions of KS/KdV tend to the solutions of the standard Korteweg-de Vries equation as . The proof relies, to a large extent, on precise estimates for oscillatory integrals that yield pointwise bounds on Green's functions.

This article explores the body and its relation to occupational/professional knowledge to understand the gendering of work practices associated with use of personal computers (PCs) in Australian family farms. The central aim of the article is to expose the gendered interactions, understandings, and communications inherent in everyday work practices and consider how these shape relations of technology and gender. In-depth semistructured personal interviews held separately with farming women and men are used to explore relations between use of information technologies, gendered work practice, and sense of self as workers. The data demonstrate that the performative aspects of masculinity result in the appropriation of knowledge by men that genders PC use and reproduces gender hierarchies in farming.


The reproductive cycle and sexual dimorphism of the lizard Cnemidophorus vacariensis Feltrim & Lema, 2000 were studied on the basis of data gathered between August 2004 and August 2006 in Vacaria, Rio Grande do Sul, Brazil. Snout-vent length (SVL) of sexually mature males varied between 48.8 and 72.9 mm (x = 63.3 ± 6.0 mm; n = 76) and, for females, between 57.4 and 81.8 mm (x = 70.0 ± 5.9 mm; n = 73). Other morphological characteristics were also compared between sexes. Reproduction was seasonal, and observations indicate two clutches in the same reproductive season. Clutch size and other reproductive characteristics were analyzed as well as the relation between reproduction and environmental factors. Cnemidophorus vacariensis is apparently endemic to highland plateaus in southern Brazil and has been classified as vulnerable on some lists of threatened fauna in this country. Some suggestions for conservation measures are presented, due to the observed degradation of this species' environment.

The behavioural investigation showed stimulatory influence of methamphetamine (Met) after both acute administration and development of sensitization. Met administration increased D1 mRNA expression; non-significantly after the first dose and significantly (p<0.006) after the challenge dose. Changes in D2 mRNA expression were not significant at all, which is to certain extent in agreement with other reports suggesting that there is no clear information whether the interaction of D1 and D2 receptors can produce a cooperative or synergistic effect on reinforcement processes


The glaciers and icebergs are important not only for the hydrology but also the ecosystem of earth. The melting of glaciers will release the stored organic carbon and further accelerate the melting rate, thus affecting the global climate. Previous explorations have demonstrated that an important factor in the glacier retreat is human emissions. Carbon particles are major components, which could further be divided in to two categories by existing forms: light-absorbing aerosols (LAAs) and light-absorbing impurities (LAIs). Nowadays, microplastic particles (MP) have been discovered as a new form of pollutants in the environment. By comparing and analyzing the data of radiative forcing (RF) as well as optical characteristics, MPs have a great potential to accelerate the melting of glaciers and an impact on the ecosystem. Therefore, further research on the MPs are necessary to be completed.


The comparison between the veterotestamentary creationist dynamics and other mythological traditions of the same space-time continuum has revealed a number of coincidences, despite the monotheistic transition carried by Hebrew ideologists. In this process, the presence of a common element stands out, symbolizing the primeval Chaos and an aquatic environment, frequently depicted under an ophiomorphic appearance. In the current article we intend to reveal some of these intercultural relationships, while trying to decipher the meaning behind the use of teratological figuration in this literary genre.


Negation handling is an important sub-task in Sentiment Analysis. Negation plays a significant role in written text. Negation terms in sentence often changes the polarity of entire sentence from positive to negative or vice versa, resulting in the opposite meaning of the sentence than what is observed by the machine learning based linguistic model. As automatic opinion mining has become very important in this digital era, proper handling of negation term is the need of the hour. In any natural language negations can be formulated both explicitly or implicitly while their use is very much domain-specific. Existing negation handling techniques follow rule-based approach and mainly used in medical domain. Due to the complex syntactic structure of negation, it is hard to build general purpose machine learning based negation handling model on user review or conversational text data. In this paper, we investigate negation components i.e., cue and scope in a sentence which determine the polarity shift in sentence. We propose LSTM based deep neural network model for negation handling task where the model automatically learns the negation features from labeled input training dataset. We used ConanDoyle story corpus for model training and testing, which is pre-annotated with negation information. The proposed model first identify negation cues in each sentence and then using bidirectional LSTM extracts the relationship between cue and other words to identify scope of the cue in sentences. We derived word level features for model training to determine correct polarity of the sentence. Result shows that the LSTM based nonlinear language models perform comparatively better than the traditional state of the art SVM, HMM or CRF based models. BiLSTM achieved best result, F1 measures 93.34%, outperform traditional rule based model in negation handling task.


A new route for the construction of 2-aminoimidazolidines including analogues of the α2 adrenergic agonist drug clonidine is elaborated. The key step is an intramolecular microwave-assisted Staudinger/aza-Wittig cyclization of an in situ generated urea intermediate (formed by the reaction of β-amino azide and isocyanate) upon treatment with Bu3P or polymer-supported phosphine reagent, allowing the introduction of various substituents at the N1 and the 2-amino function. Furthermore, a useful one-pot Staudinger/aza-Wittig/Buchwald-Hartwig protocol leading to bicyclic guanidines has been elaborated.

The purpose of this paper is to review and analyze the major function-oriented zoning and land use zoning in theoretical researches and practices in China,in order to provide prospect for the Spatial Comprehensive Zoning in the future. Methods employed were documentation and comparative analysis. Based on summarizing the theoretical and methodological research on the two kinds of zonings,the results of the paper indicate that:1) the two kinds of zonings construct the index system in order to identify regional differences from various angles; 2) in the process of zoning,researchers comprehensively use qualitative and quantitative methods and "3S" technologies. Based on all the analysis,it is concluded that the future studies should focuson spatial comprehensive zoning with an integrated natural and social factors,intelligent zoning model and dynamic zoningin the context oftemporal and spatial changings.


Problems with a gearbox can be fatal, therefore vigilance is vital. A gearbox is a key component in power transmission in various applications. Excessive load conditions or prolonged use of a gearbox in high-speed race cars or heavy working machinery leads to faults such as misalignment, increase in backlash, vibration, etc. The present work focuses on developing a technique to detect and display gear misalignments and increase in gear backlash in a gear box in real-time. The data regarding various faults are obtained using the Hall Effect sensor. This data is processed by a microcontroller and the corresponding condition of the gear, either damaged or intact, is displayed to the user in real-time. A Maruti 800 vehicle gearbox is used for this research. DRV 5055-Q1 Hall effect sensor is used to detect the faults in gears such as lateral misalignment, angular misalignment, and backlash. The developed system is capable of monitoring a gearbox effectively in real-time without the need of human intervention


The accuracy of geohazards regional analysis and geohazards risk assessment is utterly dependent on the reliability of raw geological data and the rationality of the mathematical models. To upgrade the reliability of data, geographical information system (GIS) can be used to effectively support multi resource raw geological data management, perform data processing, refine map layers for factors needed in analysis, and easily divide the region into units for analyzing use. Then, via secondary programming based on GIS, artificial neural network(ANN) model can be combined with GIS tightly, i.e., GIS takes the role of providing input data for ANN as well as processing its analysis results and outputting them in forms of maps. Combining with the trial area from Badong to Xintan in Three Gorge area of Yangtz River, the feasibility and practical methods to integrate ANN with GIS, named as GIS Based ANN, were discussed in this paper. And its application on geohazards risk assessment was illuminated too. Generally, the thoughtway is also available to resolve the combination between GIS and other mathematical models.


National information infrastructure (NII) public policy issues apply to the development of the global information infrastructure (GII) as well. Individual privacy rights; prevention of malicious behavior by irresponsible individuals; protecting the interests of computer system owners, operators, users, and the general public from computer crime; excluding unauthorized access; and preventing destruction of national computer systems (e.g.. interbank transaction systems) are issues that can be endemic to GII operations. More recent issues, such as the need for high-definition television standards, expand the global challenges. Hence, the body of work performed by the Committee on Communications and Information Policy (CCIP) for the IEEE-USA. Which focused on public policy issues of the NII, can serve as a set of lessons learned that should be considered by the GII community. The article identifies the NII issues and concerns to the CCIP, outlines the recommendations already made, and indicates how they relate to the GII.


Members of the species Astragalus cymbicarpos form chasmogamous and cleistogamous flowers, as well as a large variety of intermediate floral types. Bivariate allometry and Gould's clock models were used to investigate the possible heterochronic evolution of the cleistogamous flower from the chasmogamous flower. In three of the whorls analyzed (pistil, stamens, and corolla) comparison of chasmogamous, pseudocleistogamous, and cleistogamous flowers revealed a progressive "juvenilization" of the adult form. This paedomorphic morphology proved to be partly the result of a process of progenesis, also evident in acceleration of sexual maturity. The retardation of shape with respect to size in these three whorls suggests, however, the existence of a heterochronic process other than progenesis.


We report cyclic voltammograms of the hydrogen electrooxidation reaction on a rotating Pt ring electrode in diluted electrolytes that are either aperiodic or possess a period which is a multiple of the period of the cycling voltage. The complex voltammetric responses are experimentally studied in two electrolytes with different compositions of the base electrolyte (and thus different conductivity) as a function of the positive turning point of the applied voltage. The behavior can be rationalized in terms of the interaction between the inhibition of H2 oxidation by Pt−oxides, the roughening of the electrode due to oxide reduction and its subsequent smoothing as well as a nonnegligible uncompensated voltage drop through the electrolyte. The proposed mechanism is translated into a mathematical model consisting of a set of four ordinary differential equations. The model indeed captures the main experimental findings. Since the principle ideas do not depend on the specific kinetics of the oxidation reaction u...


Transnational German Education and Comparative Education Systems: Research and Practice (2020), edited by Benjamin Nickl, Stefan Popenici and Deane Blackler, is part of a series entitled Global Germany in Transnational Dialogues. The series takes a broad scope targeted at expanding interdisciplinary dialogue and advancing the goal to provide a renewed glance at Germany's relations to other countries since the turn of the century. The editors explicitly invite readers to apply the conversations to other transnational contexts, and that is exactly where I see one of the primary values in this compilation. This book review advances questions about the application of German transnational education projects as they relate to internationalization for society. Suggestions for further editions in the series include incorporating research from the host countries impacted by German TNE and German citizens' concerns about the societal relevance of German TNE. I have two goals for this book review: first, I aim to link the themes presented in the book to the current state of international higher education amid the challenges and changes that have been sped up by the global pandemic. Then, I will present an overview of each chapter in the book and end with closing thoughts about opportunities for development.


To seek out optimal expression conditions of recombinant human TNF α. Designing this experiment with orthogonal test,we cultured engineering bacteria strain and induced the expression of rhTNF α at 42℃, then run SDS PAGE. The expression level of rhTNF α was quantified by analysis software,and several important expression conditions were optimized by variance analysis of the data. The optimal expression condition of recombinant human TNF α is pH 7.5 ,culturing temperature 27℃, culturing time 4.5h, inducing time 5h,and the products were obtained with about 60% yield of total bacterial proteins in pilot scale fermentaion.Low culture temperature is favorable to expression of rhTNF α and can reduce formation of inclusion bodies on condition that is does not limit growth of E.coli.


During the last years, bioactive components of plants have clearly become the center of interest of numerous research projects. A diet rich in vegetables is considered to be preventive against degenerative diseases of civilization, as e.g. heart, circulatory and cancer diseases. Above all, the protective substances with an antioxidative effect, whose protective potential can be found in the field of cell protection, are in the focus of medical research. Here, secondary components of plants are especially relevant, like polyphenols, which can be found in red grapes. Other components with chemopreventive effects are betalains, which are contained in beetroot. The effect of thewell-knownnutritive antioxidants, like vitamin C and E, is intensified by the bioactive components of plants mentioned above. In combination with the trace element selenium (component of the glutathione peroxidase) they have a synergistic effect. This is why modern diet recommendations concerning the prevention of chronical degenerative diseases no longer include just a respective recommendation to consume fruits and vegetables. They also emphasize the units with an antioxidative effect, which are contained in this food.


The sense of proximity to a virtual context requires a diverse set of cues that gives a participant a sense of presence in a virtual space. The goal of our research is to provide a sense of body ownership of a virtual entity represented by a humanoid avatar or other virtual manifestation of a surrogate in virtual reality environment for sharing not only a space but also an experience. In essence, we seek a sense of Presence that transports the operator to the space inhabited by the virtual avatar in a virtual space. To arouse this sense of presence in a virtual space, we are testing a hypothesis that seeing one's own body from a first person point-of-view in the remote context is a critical element of "being there." To achieve this we introduce a method to enhance the sensation of presence for the operator who inhabits a virtual avatar by increasing the sense of body ownership.


Installation and design of metallic structure of Penglatan Hydropower Station are carried out according to its general layout and requirements for various locations and their functions.This paper presents in detail experience and ways in designing gates for different locations and selecting gate hoists for reference for similar project.


The application of ablative cooling techniques to small hypergolic bipropellant pulse rocket thrust chambers is examined. The design and performance requirements for a typical control rocket are given. A systematic approach to an integrated engine design is delineated. Advanced materials under investigation are the high silica, asbestos, carbon, and zirconiareinforced resin systems in addition to refractories and oxidation-resistant refractory coatings for nonablating thrust chamber sections. Ablative materials and refractory coating processes and control techniques are evaluated. Propellant injector aerothermodynamic effects on ablative chamber liners and the influence of pulse rocket duty cycle on over-all engine design are discussed. Empirical results of engines designed for space thrust levels of 25, 100, and 1750 Ibf for short and long pulses varying from 10 msec to 10 min are compared with analytical predictions. Accumulated burning durations of 30 min and above have been demonstrated with thrust variations of less than ±1% at an average /sp of 295 sec.


In order to identify disaster-bearing bodies in coastal cities, this paper uses the mining association rule of Apriori algorithm to construct the identification method of damaged disaster-bearing bodies in coastal cities, takes the typhoon storm surge process and temperate storm surge process that caused disasters in China's coastal cities from 1989 to 2018 as an example, and gives the minimum support threshold and the minimum confidence threshold of the Apriori association rule algorithm. The empirical results show that the damage victim identification method constructed in this paper is feasible and effective.


84 three-week old, weaned male Wistar rats were allotted randomly to 7 dietary treatments with 3 replicates per treatment and 4 rats per replicate. Rats were fed basal diet or basal diet plus 0.1, 0.2, or 0.3% P from dicalcium phosphate nanoparticle or normal dicalcium phosphate for 4 weeks. Results showed, tibia ash percentage and tibia phosphorus content of dicalcium phosphate nanoparticle groups increased significantly (P0.05), compared with normal dicalcium phosphate groups with the same supplemental level of phosphorus. Normal dicalcium phosphate was as a reference standard. Using rat's tibia ash percentage, tibia phosphorus content as response criteria, the relative biological value (RBV) of phosphorus in dicalcium phosphate nanoparticle were 127% and 125% evaluated by the slope ratio method, respectively.


Introduction The Bankart lesion is the most common form of labro-ligamentous injury in patients with traumatic dislocations of the shoulder. Various methods have been described each with its own advantages and disadvantages. We describe 5-year results of arthroscopic Bankart repair using knotless anchors. Patients and Methods There were 38 patients, with involvement of the dominant arm in 28 patients. Recurrent dislocation was the most common indication in 21 patients, followed by first dislocation in 9 patients and second dislocation in 8 patients. All patients were done under general anesthesia and regional block in beach-chair position. Standard portals were used and repair done using 2.9 mm pushlock knotless anchors (Arthrex®). Patients had sling for 4 weeks and followed by a strict physiotherapy rehab protocol. Patients were followed up at 6 weeks and 3 monthly thereafter. Results Only one patient had symptoms of recurrent instability, but was not keen on further surgery. Two patients had limitation of external rotation to 10 degrees. The mean Carter-Rowe score was 77.3. 90% of patients were happy to recommend surgery. Conclusion Arthroscopic Bankart repair appears to produce good mid-term results for patients with shoulder instability.


Plot experiment,lab experiment and statistical method were combined to investigate the effect of organic and conventional rice-crab compound cultivation models on physical and chemical characteristics of soil,rice yield and yield components,the quality of rice and economic benefits.Results revealed that the organic model obviously improved the soil fertility,and the soil bulk density decreased by 12.1%,the porosity increased by 12.2%,also the organic matter,total N,available N,available P and available K increased by 5.47 g·kg-1,0.14 g·kg-1,12.2 mg·kg-1,32.05 mg·kg-1,29.96 mg·kg-1 respectively compared to conventional model.The 1000 grain weight and seed setting weight in organic model were obviously higher than that in conventional model,while the panicle number in organic model was lower than that in conventional model,thus the rice yield in conventional model lowered correspondingly.Also the quality of rice improved,the head rice rate increased by 18.57%,the protein content decreased and obtained a better taste.The organic cultivation model could obtain an additional income of 6500 Yuan·hm-2 when calculating the organic product as 30% higher as normal product in price.

In this work, Au nanoparticle (AuNP)-modified filter paper as a highly sensitive mercury extractant was successfully prepared in situ and applied in the head-space solid phase extraction (HS-SPE) of Hg(II) in water. The microstructure of the modified filter paper was characterized by using X-ray diffraction and scanning electron microscopy (XRD/SEM), and the results showed that AuNPs were well distributed on the fiber surface of the filter paper. Combined with portable Zeeman atomic absorption spectroscopy (ZAAS), the modified filter paper was successfully applied to Hg detection in water samples. Specifically, it can easily achieve in situ sample collection and detection under negative pressure in the field, which was reported for the first time. Several influencing factors such as extraction temperature, time, stirring speed, pH value, reductants, inorganic ions, and organic interfering and complexing agents were all investigated thoroughly. The limit of detection (LOD) for Hg(II) was 0.09 μg L−1, with linearity ranging from 0.09 to 50 μg L−1. Good recoveries were also obtained between 82 and 106% with RSDs below 7% in real water samples. The established method provided a convenient route for mercury detection in environmental water with a low amount of sample required (1 mL) and good detection performance, which is comparable to that of ICP-MS.


We prove that commensurizers of two-ended subgroups with at least three coends in one-ended, finitely presented groups are invariant under quasi-isometries. We discuss a variety of applications of this result.

— This research paper explores the use of big data analytics to improve decision-making in companies. The paper begins with a comprehensive literature review that defines and examines the evolution of big data analytics, identifies theoretical frameworks for big data analytics and decision-making, and highlights the benefits and challenges of using big data analytics in decision-making. The research then utilizes a mixedmethods approach that combines expert interviews, case studies, and surveys to further explore the use of big data analytics in decision-making in companies. The findings from the literature review and empirical research demonstrate that big data analytics can significantly improve decision-making by providing businesses with timely and accurate insights, enhancing collaboration and communication, and facilitating more informed and data-driven decision-making. However, the research also highlights the importance of addressing the challenges associated with the adoption of big data analytics, such as data privacy and security concerns and the need for specialized skills and infrastructure. The research concludes with a discussion of the implications for theory and practice, as well as recommendations for future research. Overall, this research paper provides valuable insights into the use of big data analytics as a strategic tool to improve decision-making in companies.


1 The methods of Cochran & Ellner (1992) make it possible to calculate the withinstage stable age distributions for populations modelled with a stage-projection (Lefkovitch) matrix. 2 Applying these methods, I found a general pattern in the form of these distributions across a broad range of taxa: with increasing stage category, the stable age distributions become lower, more symmetric, and flatter. 3 This pattern is found in most but not all populations, and thus is not simply an artefact of the method. Exceptions tend to be populations with multiple new-born types (e.g. with both vegetative and sexual reproduction). 4 The pattern remains qualitatively the same when the number of stage classes is varied, despite quantitative differences, When the number of stages is large, the skewness and kurtosis of the within-stage age distributions appear to decline exponentially with stage. 5 The cause of the pattern seems to be the accumulation of lag times in individuals' progressing to larger stages. 6 This result can be used to test for stability, when populations can be aged directly; to modify methods for estimating age from stage, when they cannot; and to suggest the need to look for vegetative reproduction in the field, when it does not hold.


A rapid growth phase often occurs with the onset of spring in the young horse. This coincides with changes in day length, temperature, and progesterone concentrations. The change in growth, from slow to rapid in young horses has been associated with various forms of developmental orthopedic disease. The objective of this study was to distinguish associations between progesterone concentrations and other physiological and environmental measures from birth through 16 mo in young Thoroughbreds. Growth data and plasma samples were collected monthly from 3 annual crops of 20 foals. Plasma progesterone (P4) and insulin like growth factor one (IGF-I) concentrations were measured with previously validated radio immunoassay's (RIA). Progesterone concentrations were compared with day length, IGF-I and ADG using Spearman correlations. Concentrations of progesterone at birth (2.3 ± 0.4 ng/mL) decreased within the first week of life to basal values (0.11 ± 0.01 ng/mL) in colts and fillies. Progesterone in the geldings remained at baseline concentrations at all sample times. An abrupt increase in progesterone concentration was detected in fillies at a mean age of 385 ± 6.4 d, weight 381 ± 7.2 kg, and ADG 0.63 ± 0.04 kg/d. Elevations in progesterone concentrations coincided with a measured day length of 13 ± 0.1 hrs, and temperature of 15 ± 1.7 °C. Positive associations were established between progesterone concentration day length (r = 0.59; P<0.0001), IGF-I (r = 0.25; P<0.01) and ADG (r = 0.34; P<0.0001). Day length IGF-I and ADG began


Changes in patterns of participation in outdoor recreation environments may have significant impact on visitor satisfaction and may affect the kinds of recreation opportunities available. The dynamics of change, however, are among the least understood phenomena in park and recreation planning and administration. Principles of recreation behavior are used to characterize two of the most important change processes: displacement and social succession. Five types of persons are identified who are likely to be systematically discriminated against in situations of uncontrolled change. An important implication is the need for park and recreation administrators and planners to be more aware of the consequences of change, and how their actions may abet or hinder such processes.


From Abstract: "The lattice complex is to the space group what the site is to the point group - an assemblage of symmetry-related equivalent points. The Tables list site sets and lattice complexes in standard and alternate representation. The higher the symmetry of the crystal structures is, the more useful the lattice-complex approach should be on the road to the ultimate goal their classification."


Under the conditions of building a well-off society in an all-round way ,we must learn the "two musts" by heart. The "two musts"represents our Party's fine tradition ,true political quality and the base of the great vitality. It is also the necessity and guarantee of building a well-off society in an all-round way under the new circumstances. In the meantime , the "two musts"is also necessary for all the Party carders to follow for the purpose of self-cultivation.


This paper presents a new robust control scheme using sliding mode control associated with disturbance observer enhanced by varying boundary layers technique. Switching-gain of the sliding mode is adaptable on the estimated disturbance. The scheme is developed to guarantee tracking accuracy of an electro-hydraulic actuator system with robust and smooth control actions in the existence of uncertainties and the changes of external load disturbance. Robustness and smoothness of the control actions is assured if the switching gain of the control law is greater and adaptable on the bounds of the uncertainties and the disturbance. Moreover, the smoothness of the control input is enhanced by varying boundary layers technique based on the estimated disturbance. The capability of the proposed controller is validated through simulation. The simulation results indicate that the proposed scheme ensures the tracking performance with smooth control actions in different levels of the external load disturbance. This scheme offers a significant efficiency of energy in the control of EIlA systems.


Cultural humility, with its concomitant understanding of the importance of the influences of diversity and inclusion, improves health outcomes in the human medical field. Recent changes to the American Veterinary Medical Association Council on Education requirements in veterinary medicine include teaching the impact of implicit bias on the delivery of veterinary medical services. Because overt enhancement of self-awareness is not fodder for traditional veterinary medical education delivery systems, in this article we review existing literature on the impact of recognition of implicit bias on health care and offer insights on ways to help veterinary students learn this skill, drawing on evidence from an inter-professional intervention called WisCARES (Wisconsin Companion Animal Resources, Education, and Social Services).

Socialization and training of the use of learning media based on learning management system (LMS) with moodle for junior high school teachers at Methodist 8 Medan aims to improve teachers' knowledge and skills in integrating Information Technology and Communication (ICT) into interactive, interesting and fun online learning. Moodle is a software application produced for dynamic learning activities based on technology, internet and websites. The methods that used for implementing this Community Partnership Program are socialization and training which begin with preliminary observations, analysis of learning problems and the needs of teachers and students. The next stage is the preparation of activities both from the partners and the team. The third and fourth stages are socialization and training on the use of learning media based on LMS by using the Moodle features. The result of this partnership program is that teaching materials such as power point presentation, learning videos, assignments and quizzes/student worksheets have been created and uploaded by utilizing the features in Moodle.


In this note, we prove that matrices whose entries are all 0 or 1 cannot achieve good performance with respect to the Restricted Isometry Property (RIP). Most currently known deterministic constructions of matrices satisfying the RIP fall into this category, and hence these constructions suffer inherent limitations. In particular, we show that DeVore's construction of matrices satisfying the RIP is close to optimal once we add the constraint that all entries of the matrix are 0 or 1.


: In the construction of the teaching system of applied undergraduate programmes, the value of "application" is highlighted, and high-quality talents with strong social adaptability and competitiveness are cultivated, which has certain requirements for the communication, writing, teamwork and innovation abilities of university students. Currently, there are many problems in writing among university students, who do not pay enough attention to writing courses and rely too much on artificial intelligence to write, lacking creative independence. The lack of writing skills also brings with it many problems, as many students find it difficult to write project books and application essays when they enter society, which does not help them to adapt quickly to the workplace. At the same time, communication skills are an important assessment factor for graduates when they first enter the workplace, and many general education courses at this stage neglect the development of communication skills. Therefore, in order to quickly solve the dilemma of the teaching mode of traditional writing courses, Liaoning Institute of Foreign Trade and Economic Cooperation offers the Writing and Communication course, which starts and ends with improving students' writing and communication in the workplace, and is student-centred, helping students to improve their writing and communication in the workplace and develop critical thinking skills through innovative teaching modes and improved assessment and evaluation, which helps to improve students' overall quality and cultivate Application-oriented talents.


The continuing desktop computing revolution, major re‐design and re‐implementation by a number of vendors of integrated library systems, widespread public acceptance and use of the Internet/World‐Wide Web, and the increasing use of the Internet to deliver digital content and access to electronic resources, have all combined to create the need for libraries in the United States to enhance and replace existing systems, networks, and other technologies and to implement new technologies. Libraries planning new network‐centric services face the prospect of overall technology enhancement to optimise service delivery; technology support and staff training and development become critical for successful implementation. This paper reviews the issues that libraries will have to address as they move to the 'next‐generation' systems.


The Careon unit consists of imbricate tectonic sheets of serpentinite, metagabbro, and diabase dikes interpreted as a dismembered ophiolitic sequence. Zircons from leucogabbro intruding serpentinites point to an igneous crystallization at 395 ± 3 Ma, in accord with previous results. Combined with a reported 377 ± 1 Ma Ar/Ar cooling age, this date implies that ophiolite generation occurred shortly before its tectonic emplacement. Most samples are enriched in light rare earth elements (REE) relative to heavy REEs and show distinct fractionation of the heavy REEs. Enrichments in Th and La relative to Nb are ubiquitous, while negative anomalies of Zr and Ti occur in most samples. Initial e Nd values (+6.4 to +9.1), even for samples with high light REE/heavy REE ratios, point to a time-integrated mantle source strongly depleted in Nd relative to Sm, and preclude significant contamination of mafic melts during their ascent through the crust. Combined trace element and Nd-isotope data favor an intraoceanic, suprasubduction-zone setting, where hydrous fluids and silicate melts metasomatized a wedge of depleted mantle and triggered its partial melting. On the basis of magmatic affinities, age constraints, and broad tectonometamorphic context, ophiolite generation is interpreted to reflect oceanic spreading above a subduction zone dipping away from a passive continental margin. Suprasubduction extension might have been associated with subduction hinge retreat caused by instability of old, cold oceanic lithosphere entering the subduction zone. It is suggested that this occurred in the context of early stage arc collision documented at that epoch in the Variscan realm.

Training Legal Translators and Interpreters (TLTI) is gaining weight and momentum in many translator/interpreter-training institutions all over the world, and it has become an integral part of Translation Studies (TS). In Palestine, however, TLTI has been a neglected area until quite recently. The establishment of Palestinian Authority, pursuant to the Oslo Accords between the Palestine Liberation Organisation and Israel has brought about political changes in Palestine which seemed to have taken a major step forward. The need for more qualified translators/interpreters has become urgent. New (post)graduate programmes have been established in several local Palestinian universities with a view to prepare qualified legal translators/interpreters for the emerging translation market. Other attempts to introduce nonacademic training courses have also been made. This paper aims to explore the status of (non-) academic training in Palestine; it will examine laying the groundwork for TLTI in Palestine, based on an analysis of the examination for translators/interpreters made by the Palestinian Ministry of Justice (PMoJ). Accredited sworn translator/interpreter is awarded to the successful examinees. Analysis for the legal-oriented examination held for the past three years shows that Palestinian translators and interpreters have serious translation problems caused not only by the lure of legal language, but it is also attributed to the lack of professionally-oriented training. The paper reveals that the examinees who have received (non-)academic training managed to pass the exam whereas those who rely solely on experience did not. The paper also shows that the problematic areas the translators/interpreters encounter fall into three categories: syntax, layout and tenor.


The Institute of Space Systems at Technische Universitat Braunschweig has long-term experience in the field of space debris modeling. This article reviews the current state of ongoing research in this area. Extensive activities are currently underway to update the European space debris model MASTER. In addition to updating the historical population, the future evolution of the space debris environment is also being investigated. The competencies developed within these activities are used to address current problems with regard to the possibility of an increasing number of catastrophic collisions. Related research areas include, for example, research in the field of orbit determination and the simulation of sensor systems for the acquisition and cataloging of orbital objects. In particular, the ability to provide simulated measurement data for object populations in almost all size ranges is an important prerequisite for these investigations. Some selected results on the distribution of space debris on Earth orbit are presented in terms of spatial density. Furthermore, specific fragmentation events will be discussed.


In this paper we will argue that sensor networks in which multimodal sensors are connected to each other and computational devices capable of data mining, offer the possibility of serendipitous and opportunistic sensing in which unanticipated associations are detected and used to produce more robust event recognition. To illustrate this point of view, we outline two simple scenarios and conduct some preliminary experiments to show that this type of on-the-fly data analysis can indeed be useful.


ABSTRACT Understanding urbanization dynamics, or how intensity of urbanization changes over time, is an important basis for urban planning and management, which has been investigated using various data-driven approaches. Considering the advantages and constraints of different data sources, we use pixel-based, time-series night-time light (NTL) trajectories to characterize urbanization dynamics in mainland China where massive urban development has been occurring in recent decades. After pre-processing the data, we extracted time-series NTL trajectories for each 1 km × 1 km pixel between 1992 and 2013 and used the unsupervised k-means classification to identify the major typologies of these trajectories as urbanization dynamics based on their main statistical parameters. The classification identified five urbanization dynamics, namely, stable urban activity, high-level steady growth, acceleration, low-level steady growth, and fluctuation. Their distributions and spatial patterns were further summarized and compared among different Chinese administrative divisions. We specifically analysed the acceleration trajectories that showed rapid transitions from rural to urban, as we considered these trajectories as potential indicators for aggressive urbanization. We found several clusters at prefecture city and county levels with high proportion of the acceleration, and referred to the underlying socioeconomic characteristics and developmental history to understand how these clusters could had been formed. Through this study, we revealed the dominant tendencies of urbanization in China over space and time, and developed an analysis framework that could be extended to other regions.


Crystal oscillators use an external crystal to generate clock signals for designs that require high stability at a precise frequency. Phase-locked-loops are used to multiply the crystal output frequency to higher values. This application note describes the use of Crystal Oscillator and PLLs in the context of the AT91M42800A and AT91M55800A ARM-based microcontrollers. The ZIP file " Automatic_Calculation_xls.zip " should be downloaded from the Software section of the AT91 pages on Atmel's web site and unzipped. It gives a spreadsheet that is programmed to perform the calculations described in this application note. The mechanical impedance of a crystal for one particular series resonant frequency k (the fundamental and its overtones) can be electrically modelled by a series RLC resonant circuit. See Figure 1. The parasitic capacitance of the crystal's electrodes and the package are modelled by the capacitor C 0. Together with the motional inductance Lx(k) this capacitor forms resonant circuits that also produce parallel resonant frequencies fp(k). They cannot be used for oscillation with the type of oscillators presented here.


The province of Manabí is subject to different risks, one of them is seismic. When this phenomenon occurs, they endanger all elements of society; but not only that, because the consequences of these reach further and can compromise the environmental situation of a locality when they are able to produce changes in the orography of the land modifying the landscape. Many buildings collapse and others are affected, transforming the environment in an important way. The research aims to show some environmental risks that occurred when this type of natural phenomenon occurs, for which a bibliographic review was used as a methodology, appealing to the experiences derived from the effects of the earthquake in the city of Portoviejo on April 16 of 2016, where it was possible to see abandoned areas that previously had a high functional and social value, soils have acquired other types of values; but also where different environmental impacts and changes of landscape affected by natural phenomenon are observed.


We consider a collaborative opportunistic scheduling problem in a decentralized network with heterogeneous users. While most related researches focus on solutions for optimizing decentralized systems' total performance, we proceed in another direction. Two problems are specifically investigated. (1) With heterogenous users having personal demands, is it possible to have it met by designing distributed opportunistic policies? (2) With a decentralized mechanism, how can we prevent selfish behaviors and enforce collaboration? In our research, we first introduce a multiuser network model along with a scheduling problem constrained by individual throughput requirement at each user's side. An iterative algorithm is then proposed to characterize a solution for the scheduling problem, based on which collaborative opportunistic scheduling scheme is enabled. Properties of the algorithm, including convergence, will be discussed. Furthermore in order to keep the users staying with the collaboration state, an additional punishment strategy is designed. Therefore selfish deviation can be detected and disciplined so that collaboration is enforced. We demonstrate our main findings with both analysis and simulations.


R.W., a 21-year-old football player, was injured while tackling. One of his team mates, simultaneously tackling the same opponent from the opposite side, struck the patient's wrist with his helmet.


The computation of the contrast of fourth order interferences done to study the EPR paradox gives different results in quantum and semi-classical theories. A larger contrast is obtained by the quantum theory using elementary computations but it is the contrary by using the more refined semi-classical treatments. In some of the four examples given, simple complementary hypothesis may be required.


Socialist land management of China originated in 1950's with certain achievements.Before the reform and opening-up,land management in China was conducted under a system of multi-department administration.Since the reform and opening-up,urban and rural land has been managed in a unified way,and then the markets of paid use and urban land emerged,which in turn resulted in the regulations of land market and land supervision in the cities.The reform and opening-up has led to a new era of land management as well as the prime period of land management.


Large grains of high temperature superconducting (HTS) material can be utilized as trapped field magnets (TFMs). Persistent currents are set up in the HTS when it is cooled in a magnetic field, or exposed to a magnetic field after cooling. TFMs have been improved over the past two decades by the efforts of a large number of worldwide research groups. However, applications using TFMs have lagged, in part due to the problem of high fields needed for activation. We describe herein experiments designed to observe the behaviour of TFM activation using repeated applications of low fields (called 'pumping'). Significant partial activation is obtained using a non-uniform pumping field (e.g., a small permanent magnet) which is higher in the centre of the HTS than at the periphery. Cooling in zero field followed by pumping with such a field results in trapping the full applied field, in comparison to half of the applied field being trapped by cooling in zero field followed by application of a uniform field. We find that for partial activation by cooling in a field and subsequent activation by pumping, the resulting fields are additive. We also conclude that for activation by fluxoid pumping, creep assists the process.


The notion of coupled fixed point was introduced by Guo and Laksmikantham [12]. Later Gnana Bhaskar and Lakshmikantham in [11] investigated the coupled fixed points in the setting of partially ordered set by defining the notion of mixed monotone property. Very recently, the concept of tripled fixed point was introduced by Berinde and Borcut [7]. Following this trend, Karapinar[19] defined the quadruple fixed point. In this manuscript, quadruple fixed point is discussed and some new fixed point theorems are obtained on partial metric spaces.


Though there are adequate institutional frameworks and legal instruments for the protection of the Sub-Saharan African environment, their impact on the development and conservation (protection) of the environment leaves much to be desired. This assertion is substantiated by the reality that inspite of these regulatory frameworks, the environment is largely degraded with negative ramifications for the twin goals of attaining sustainable socio-economic advancement and realization of environmental rights. Both national and regional state of environment (SoE) reports show that degradation is apparent. It is worthy of mention that almost all African countries have ratified and domesticated the various regional and subregional environmental agreement. Efforts to solve the puzzle have revealed that corruption and environmental degradation in Sub-Saharan Africa are closely linked. Financial impropriety in ecological funds management, poorly equipped environmental protection institutions, and inadequate citizens' environmental management awareness campaigns are outcomes of corruption in the public sector. Since corruption thrives in the absence of transparency and accountability, this study proposes a cutting-edge technology-based solution that promotes participatory environmental accountability using an e-Environment system. The web-based multi-tier e-Environment system will empower both citizens and government officials to deliberate online real-time on environmental policies, programmes and projects to be embarked upon. Both parties will equally put forward proposals on the use of tax payers money in the environment sector while monitoring discrepancies between amount budgeted, amount released and actual amount spent. We applied design and software engineering skills to actualize the proposed solution. Using Nigeria as case study, our research methodology comprised literature review, requirements gathering, design of proposed solution using universal modelling language (UML) and development/implementation on the Microsoft SharePoint platform. In view of our determination to evolve a zero-defect software, we applied Cleanroom Software Engineering techniques. The outcome obtained so far has proved that the model supports our expectations. The system is not only practical, but ecologically sound. It is anticipated that the full-scale implementation of such an enterprise e-Environment system will decrease the current tide of corruption in the environment sector, mitigate environmental degradation and by extension, reduce social-economic tensions and guarantee national security.

Through taking benzaldehyde and EG as raw materials and supported phosphotungstic acid as catalyst,the benzaldehyde ethylene glycol acetal was synthesized to study the influence of the molar ratio of aldol,the reaction time,the amount of catalyst and cyclohexane and other factors on the yield.The results showed that the optimum reaction conditions of the synthesis of benzaldehyde glycol acetal by phosphotungstic acid are:benzaldehyde 0.2 mol,n(benzaldehyde):n(EG)=1.0:1.5,the amount of catalyst covers 6.2% of the total mass of reactants,cyclohexane 10 mL,and 90-105 ℃ under reflux for 30 min.The yield of benzaldehyde ethylene glycol acetal can reach over 84% under these conditions.


Acceleration of electrons up to energies in the MeV range has been observed in JET during combined application of Lower Hybrid and Fast Waves in fully non‐inductively driven discharges. Without Fast Wave, the energy of the fast electrons remains below 200 keV. Up to 18% of the Fast Wave power has been estimated to be coupled to the fast electron population. This additional acceleration of electrons is defined as synergy between LH and Fast Wave. Specific experiments have indicated that the most likely responsible mechanism is the damping on fast electrons of an Ion Berstein Wave generated after mode conversion of the Fast Wave. The new JET RF systems, which are being prepared, (10 MW of Lower Hybrid and up to 20 MW of ICRF power at arbitrary phasing) will allow to assess if this synergism can be used to achieve the current drive efficiencies required in a reactor.


Although prior researches have been investigated the impact of insured cost(direct cost) on employers and employees, little work has attempted to categorize the items of unsecured cost(indirect cost) by accidents. On this basis, the goal of this study was to achieve a better understanding of the nature of accident cost of unsecured cost. Specifically, this study aimed to categorize the unsecured cost items according to the domestic industry circumstances and use these results for a basis of other accident cost related studies. The results of this study are as follows: (1) accident development steps were categorized as twelve items for improved management according to each step of accident development (2) the points of occurrence and termination of the unsecured cost were identified for the improved management according to each step of accident development and (3) characteristics of each item in unsecured cost were studied and identified for a better control of accident costs. These results provide a basis for further researches on the unsecured cost.


In this paper they are analyzed the ethnonyms known among the Buryats in the form of Manǰiraγ [Manǯirag˱], Malǰiraγ [Malǯirag˱] etc. (those are Manžirak, Manžirak in Russian spelling, "Manzir" in Russian documents of the 17th century), and among the Yakuts to be attested as Maldˊaγar. The Buryat forms reflected the original *Manǰi Uraγ or *Malǰi Uraγ, where attested in both cases the first element characterized by the development of complex -nǰ- > -lǰ-. The secondary form may be found also in mentioned Yakut Maldˊaγar that to be metathesised version of *Maldˊǝraχ < *Malǰiraγ, due to development of Mong. -raγ > Yak. *-raχ > -γar. So, it is possible to view here another Mongolic borrowing in the register of Yakut ethnonyms. The etymology of the original ethnonym was also analysed in the paper. The word is not based on roots such nor as Manču ~ Manǰu, that is the ethnic name of Manchu people, nor the from Buddhist lexicon word Bandi 'novice, pupil of a lama' (> Kalm. Manži), because of problems in chronology for possibility of any of such versions. So, it is of the possible the most optimal version seems to prefer the word analysed to be compared with known in Written Mongolian manǰi 'an elk'. It may be to argue that the development -nǰ- > -lǰ- attested had made place already in the form of the word have not yet been a part of the ethnonym contracted. Among Tofalars it is known the tribal name Maldˊär < *Malǰi är 'Malǰi people, people of Malǰi',. It seems that among both Yakuts and Tofalars it is circulated the secondary form of the Mongolic name. The penetration of the word here had started before 17th century. And one can say also that not only the development -nǰ- > -lǰ- had its place to that time that supported by known among Yakuts personal name attested in Russian spelling as Malegar, i.e., *Maläγar [*Maljäγar], but it was also the Middle Mongolic /ǰ/ > Buryat */dz/ reflected in Russian spelling "Manzirskiy" found in documents of the 17th century.


We investigated fluid shifts and regulatory responses to variations of posture, exercise, Gz level and radius of rotation in subjects riding NASA Ames 20G centrifuge. Results are from 4 protocols that address radius and exercise effects only. Protocol A: After 10 min supine control, 12 healthy men (35 plus or minus 9 yr, 82.8 plus or minus 7.9 kg) were exposed to rotational 1 Gz (2.5 m radius) for 2 min followed by 20 min alternating between 1 and 1.25 Gz. Blood samples were taken pre and post spin. Protocol B: Same as A, but lower limb exercise (70% V02max) preceded ramps to 1.25 Gz. Protocol C: Same as A but radius of rotation 8.3 m. Protocol D: Same as B but at 8.3 m. The 8 subjects who completed all protocols, increased heart rate (HR) from control, on average, by: A: 5, B: 39, C: 11, D: 44 bpm. For thoracic fluid volume, (bioimpedance), the 8 subjects changed from control, on average: A: -394, B: -548, C: -537, D: -708 mL. For thigh fluid volume, changes from control, on average, were: A: -137, B: 129, C: -75, D: 159 mL. Hematocrit changes from control were: A: 2.3, B: 3.5, C: 2.3, D: 4.3 %. Radius effects were mild and included greater loss of fluid from the thorax, less fluid loss from the thigh and increased heart rate at the longer radius. Pre-acceleration exercise effects were more dramatic and included additional loss of fluid from the chest, increased fluid volume of the thigh, increased hematocrit and greater heart rate increases. We propose that short bouts of intense exercise can be used to magnify the cardiovascular stress delivered by artificial gravity (AG) training and the combination of AG with exercise training can be fine-tuned to preserve orthostatic tolerance of astronauts during spaceflight.


To maximize the opportunities for the adoption of newly developed products, there is a need to better understand how psychological factors have an impact on the acceptance and deployment of innovative technology in industry. While there is extensive general literature on the psychological factors that influence consumer behavior and the use of new technologies, there seemed to be very limited understanding of this topic, specifically relating to the upstream energy sector. A literature review was conducted to (1) identify what, if any, research has been conducted in relation to the psychological factors influencing technology adoption and deployment in the oil and gas (O&G) industry and (2) identify what interventions have been developed to support technology adoption in O&G.
 A literature search was undertaken, and given the limited research anticipated, minimum selection criteria were applied on the basis of Cochrane quality control (Higgins and Green 2011). In the 17 articles that met the search criteria, there was limited discussion of the psychological factors that have an impact on O&G technology adoption. The articles were subject to Braun and Clarke (2006) thematic analysis, producing a list of psychological factors that influence technology adoption in O&G.
 Only five psychological factors were identified: personality (e.g., exploration traits and risk aversion), attitude (e.g., trust and not-invented-here syndrome), social (e.g., social norms), cognition (e.g., risk perception), and psychological factors at an organizational level (leadership and organizational culture). In addition, our review identified a small number of interventions that were developed and deployed to support technology adoption in O&G.
 Given the early stages of this research area, combined with the relevance for technology innovation in upstream O&G, our review adds to the literature by identifying an initial framework of the key psychological factors. This essential set of factors can be used to direct future research, as well as to support effective interventions aimed at supporting the introduction of new technology.


Bacillus cereus group or B. cereus sensu lato (s.l.), is comprised of Gram-positive spore-forming, rod-like bacteria that are widespread in natural environments. Although the species in this group are known to be highly related in terms of phenotypic characteristics, they display different levels of pathogenicity. Biochemical assays are therefore considered to be insufficient for accurate taxonomic classification of B. cereus group species. To facilitate accurate taxonomic classification and associated prediction of pathogenic potential, we have conducted comparative genomic analyses of publicly available genome assemblies of B. cereus group isolates. Through that, we found that an isolate previously known as B. mycoides ATCC 21929 was sufficiently distant from valid and effective type strains to be considered a putative new species. We have conducted biochemical and bioinformatic characterization of strain ATCC 21929 that had been isolated from soil in Papua New Guinea. Strain ATCC 21929 most closely resembles B. paramycoides NH24A2T, producing ANIb and DDH values of 86.70% and 34.1%, respectively. Phenotypically, isolate ATCC 21929 does not possess cytochrome c oxidase activity, and is able to grow at a range of temperatures 15°C - 43°C and at a range of pH 6 - 9. With regards to fatty acid composition, this isolate has iso-C17:0 in highest abundance. We propose the strain ATCC 21929T (=PS00077AT = PS00077BT = PSU-0922T = BHPT) as a new species named Bacillus clarus sp. nov. to facilitate accurate taxonomic classification of B. cereus group isolates.


In recent weeks, equity markets have been very weak and the euro exchange rate has risen by more than 10 per cent against the dollar. The UK's effective exchange rate has also depreciated, removing some, but not all, of the overvaluation we identified in the April Review. We report on recent movements in table 1, and their implications are discussed in the UK and World forecast chapters in this Review. To an extent the movements in the US stock markets and the exchange rate are linked, but there does seem to be some 'excess strength' in the euro, which will in turn contribute to the weakness of Euro Area equity prices.


Case Report. A 63-year-old man was admitted to our hospital due to recent onset chest pain with radiation to the left arm, which was precipitated by minimum efforts and relieved by rest. He was evaluated at the coronary care unit and treated with aspirin, heparin and intravenous nitroglycerin. The electrocardiogram revealed a T-wave inversion in leads V4, V5, V6, D1, and AVL. His coronary risk factors were diabetes type II treated with an oral hypoglycemic agent, and dyslipedemia treated with statins. He was also a smoker. Physical examination in the Coronary Care Unit was remarkable for a regular heart rate of 72 beats per minute, blood pressure of 130/80 mmHg, a respiratory rate of 15 breaths per minute, height of 1.71 cm, weight of 77 kg, and a body mass index of 26 kg/m 2 . Neck veins were not distended and no carotid bruits were heard. The heart sounds were normal without any murmurs or gallops. The lung auscultation revealed normal breath sounds The peripheral pulses were normal. The chest radiograph showed a normal heart image. Considering his risk factors and EKG changes, the patient was referred to our catheterization laboratory for angiography, which showed severe stenoses in the first diagonal (74.2%), mid portion of the right coronary artery (78%), and mid left anterior descending artery (62.5%) (Figure 1); by quantitative coronary angiography analysis, the reference vessel size for LAD and diagonal were 2.5 and 2.0 mm, respectively.


Aims and Background Prostate cancer is the most common malignant tumor in men. Serum prostate-specific antigen (PSA), Gleason score and clinical range at the time of diagnosis are important factors to predict prognosis and outcome after therapy but additional accurate and reliable biomarkers are still wanted. So far, few biomarkers of prostate cancer have been successfully implemented and are being used in clinical practice. However, modifications of E-cadherin and MMP-13 expression are likely to be involved in prostate cancer invasion and thus are potential biomarkers for prognosis. Patients and Methods We analyzed the concentrations of E-cadherin and MMP-13 in plasma of patients with prostate cancer at diagnosis and 3 and 6 months after the beginning of treatment and related these measures to free and total PSA and other clinical features. Results The concentration of E-cadherin was lower in patients with prostate cancer compared to the control group, but there was no difference in the concentration of MMP-13 between these two groups. During treatment, however, we found no significant differences between the concentrations of MMP-13 and E-cadherin, but we observed a significant positive correlation between total PSA and E-cadherin plasma concentration at the third month of treatment and between total testosterone and MMP-13 plasma concentration before the start of treatment. Conclusions The results suggest that these parameters could be used both in the diagnosis and prognosis of prostate cancer.


The formal description and analysis of protocol is an important prerequisite for protocol implementation and testing. We can utilize it to reduce the defects in the design of the protocol, to improve the efficiency of protocol development and to promote the development of protocol Standardization. In this paper, firstly we study the working precedure of FTP, and then we used petri net to give a formalized description of FTP concentrating on its control connection and data connection. On the basis of previous work, we analyzed the boundedness, reversibility and liveness of FTP through building up its reachability tree. In that case we can further the analysis of FTP protocol and improve it.

The activation of human herpesvirus‐6 (HHV‐6) commonly coexists with that of cytomegalovirus (CMV) in organ transplant recipients. No data exist of HHV‐6 in renal allografts, whereas persistent CMV in the kidney associates with poor outcome and histopathologic changes. We examined HHV‐6 and CMV antigens from kidney transplants with previous CMV infection. HHV‐6 and CMV pp65 antigens were demonstrated by monoclonal antibodies and immunohistochemistry from 22 kidney transplants with previous CMV infection. CMV was diagnosed by antigenemia tests and/or viral cultures. HHV‐6 antigens were found in 7/22 biopsies 18–1330 days after CMV infection, in infiltrating leukocytes in six, and in tubular epithelial cells in two patients. CMV infections were treated, and no virus could be detected from urine or blood thereafter, or at the time of the biopsy. Only 1/7 of these biopsies demonstrated also CMV antigens, whereas CMV antigens were found in 6/15 of the biopsies with no HHV‐6. HHV‐6 in the graft was associated with previous acute rejections, but not with any histopathological changes or reduced renal function. In conclusion, HHV‐6 was a common finding in late renal allograft biopsies of patients with previous CMV infection, but its significance remains to be elucidated.


The nature of warfare is changing. Increasingly, developments in military technology are removing soldiers from the battlefield, enabling war to be waged from afar. Bombs can be dropped from unmanned drones flying above the range of retaliation. Missiles can be launched, at minimal cost, from ships 200 miles to sea. Micro Air Vehicles, or 'WASPS', will soon be able to lethally attack enemy soldiers. Though still in the developmental stage, progress is rapidly being made towards autonomous weaponry capable of selecting, pursuing, and destroying targets without the necessity for human instruction. These developments have a profound — and as yet under-analysed — impact on just war theory. I argue that a state under attack from remote weaponry is unable to respond in the traditional, just war sanctioned, method of targeting combatants on the battlefield. This restriction of options potentially creates a situation whereby a state is either coerced into surrender, or it must transgress civilian immunity. Just war theory in conditions of remote warfare therefore either serves the interests of the technologically advanced by demanding the surrender of targeted states, or else it becomes redundant.

Recently, two-dimensional boron sheets have attracted a lot of attentions owing to their structural polymorphs and outstanding properties. And, due to chemical complexity and electron deficiency of B atoms, the 2D boron sheets are easy affected by the environment. So, exploring novel 2D boron oxides gets highly needed. In this study, we theoretically explored 2D boron oxides structures and their basic properties. We found 2D boron oxides are metals or semimetals, when oxygen concentration is low. More interesting, the B6O1 exhibits Dirac Loop near the Fermi level and the maximum Fermi velocity is estimated as high as 0.61*10E6 m/s, which much close to that in graphene. In addition, when the oxygen concentration is one forth, the most stable B4O1 get a semiconductor with a direct band gap of 1.24 eV and a strong anisotropic carrier mobility. Such huge differences of carrier mobility between two directions have not been reported in other 2D materials. Besides, when oxygen concentra-tion is higher than one forth, the 2D boron sheets will get unstable based our results. We also proposed a method how to synthesize these systems. Our work provide a basic knowledge of 2D boron oxides and may lead to novel 2D boron oxides discovered. The unique electronic properties of the B6O1 and B4O1 render them promising 2D materials for applications in high-performance nanodevices.


The liquid-solid separation behaviour of lead(Ⅱ)with potassium iodide-methyl violet-water system and the conditions for separation of lead(Ⅱ)from other metal ions were studied.The results show that in the presence of 0.6 mL KI(0.1 mol/L)and 0.2 mL MV(1.0×10-3 mol/L)solution,Pb(Ⅱ)can react with I-and methyl violet(MV+)to form the settling of(MV)_2(PbI_4),whereas Zn(Ⅱ),Cd(Ⅱ),Cu(Ⅱ),Mn(Ⅱ),Co(Ⅱ),Ni(Ⅱ),Fe(Ⅱ),Al(Ⅲ)can not in this conditions.Pb(Ⅱ)can be separated completely from these metal ions.This method has been used for the separation of trace of Pb(Ⅱ)in synthetic water samples with satisfactory results.


This study examines the presence of the Ulysses myth in Modern Greek poetry of the 20th century. It contains a thematic comparison of different motifs of the myth, as told in the Odyssey of Homer. The main methodology used for this study is based on the theories of intertextuality. Various rearrangements and reinterpretations of the myth, concerning either the personalities of the mythical figures or certain events of the epopee, are examined and analysed in the present thesis. The Ulysses myth has interested many authors all over the world including a considerable number of Greek authors. During the last century, recourse to the ancient myths has been proven very important, and, together with the political events in Greece and the literary movements, offers a rich study material. The Greek poets –cosmopolites, traditional bourgeoisie, communists, surrealists etc. – have treated the myth each by emphasising the aspect that seemed most important according to his ideology and poetics. Thus, we have attempted to perceive the evolution of the Ulysses myth in parallel with the history of Greece over last century.
