Research on a Microgrid Subsidy Strategy Based on Operational Efficiency of the Industry Chain

Government subsidy is a powerful tool to motivate the development of a new energy industry. At the early stage of microgrid development, for the sake of the cost and benefit issue, it is necessary for the government to subsidize so as to support and promote the development of microgrids. However, a big challenge in practice is how to optimize the operational efficiency of the microgrid industry chain with varying targets and methods of subsidy. In order to explore this problem, we construct a subsidy model based on the microgrid industry chain, involving government, investor, operator, equipment supplier, and user. Through calculation and solution of this model, we obtain price and return indicators of each microgrid industry chain participant when the subsidy target differs. Based on that, we contrast and compare the optimal subsidy strategy and influencing factors when operational efficiency indicators vary. Finally, we validate and analyze this model with numerical analysis and discuss the impact of development stage, technological level, and change in subsidy amount on the operational efficiency of the microgrid industry chain and on the returns of each participant. This result is of great significance to subsidy practice for microgrids and the development of microgrids.
On the Analysis of the Contact Conditions in Temporomandibular Joint Prostheses

Temporomandibular joint replacement (TMJR) is a complex surgical procedure in which the artificial joints available must assure the anatomical reconstruction and guarantee a good range of the natural temporomandibular joint (TMJ) movements. With this aim, different types of TMJ prostheses, including the stock prosthetic system and custom-made prostheses, are being currently implanted. Although temporomandibular joint replacements (TMJRs) are expected to accomplish their function during a number of years, they might actually fail and need to be replaced. This paper analyzes different design factors affecting the contact stress distributions within the TMJ prosthesis interface, which are consequently involved in their deterioration and final failure of the prosthetic device. With this purpose, a numerical model based on finite elements has been carried out in order to evaluate the stress states attained in different prosthesis configurations corresponding to general types of TMJ prostheses. On the other hand, the actual degradation of resected implants has been evaluated via optical microscopy. The linkage between the numerical simulations performed and experimental evidence allowed the authors to establish the different wear and damage mechanisms involved in the failure of stock TMJ prostheses. Indeed, the results obtained show that the contact stresses at the interface between the mandible and the glenoid fossa components play a key role in the failure process of the TMJR devices.
Appendix for Inequality , Leverage and Crises

The solution method that is used in this paper adapts the time-iterative policy function algorithm described by Coleman (1991) to allow for endogenous default decisions. In this appendix we outline the main steps of the algorithm. More detailed explanations accompany the source code, which is available at http://www.mosphere. fr/ les/krw2014.
Lowest Unique Bid Auctions with Signals

A lowest unique bid auction allocates a good to the agent who submits the lowest bid that is not matched by any other bid. This peculiar auction format is becoming increasingly popular over the Internet. We show that when all the bidders are rational such a selling mechanism can lead to positive profits only if there is a large mismatch between the auctioneer's and the bidders' valuation. On the contrary, the auction becomes highly lucrative if at least some bidders are myopic. In this second case, we analyze the key role played by the existence of some private signals that the seller sends to the bidders about the status of their bids. Data about actual auctions confirm the profitability of the mechanism and the limited rationality of the bidders.
Universitet Noise , Information , and the Favorite-Longshot Bias

According to the favorite-longshot bias, longshots are overbet relative to favorites. We propose an explanation for this bias (and its reverse) based on an equilibrium model of informed betting in parimutuel markets. The bias arises because bettors take positions without knowing the positions simultaneously taken by other privately informed bettors. The direction and the extent of the bias depend on the amount of private information relative to noise present in the market. With realistic ex-post noise and ex-ante asymmetries, our model replicates the main qualitative features of expected returns observed in horse races.
EFFECTS OF CULTIVAR AND ENVIRONMENTAL CONDITIONS ON BILLET PLANTING TOLERANCE

Billet planting is a desirable but problematic planting option for sugarcane in Louisiana. Higher costs and greater risk of stand failure have limited adoption of billet planting. The extent of variation in yield due to genotype and environmental factors is not known. Therefore, sucrose yield and its components were compared for billet and whole stalk plantings of eight sugarcane cultivars in four multiple-year crop cycles. Comparison to yields obtained with whole stalk planting was used to assess tolerance to billet planting among cultivars. Billet planting yields were lower compared to whole stalk plantings for some cultivars but were equivalent for others. Lower yields in billet plantings were most evident in the plant cane crop. Results varied among cultivars and between experiments. Environmental conditions varied after planting in different years, and stressful conditions differentially affected stand establishment in billet plantings of different cultivars. The results indicate that tolerance to billet planting varies among cultivars with the performance in some cultivars being affected by conditions after planting. Environmental stress increases the likelihood of reduced stands and yield in billet plantings for some cultivars. Drought or wet conditions after planting, cold and wet winter weather, and freezes are contributing stress factors. The results also suggest tolerance to billet planting may decrease in some cultivars over time. Tolerance to billet planting is apparently a complex and variable trait that will need to be determined for individual cultivars.
Improvement of the sputtered platinum utilization in proton exchange membrane fuel cells using plasma-based carbon nanofibres

Proton exchange membrane fuel cells are complex nanostructures containing a catalyst (usually platinum), proton and electron conductors and pores. Their electrode performance is strongly influenced by the size, the repartition and the orientation of the nanoseparated materials used and the pores. This paper investigates the electrical performance achieved by three designs of plasma-prepared Pt/C electrodes with low Pt loadings (from 0.01 to 0.1 mgPt cm−2). A plasma sputtering process was used for the synthesis of Pt nano-clusters in three different microporous supports: a single oriented layer based on aligned carbon nanofibres (CNFs, custom-made by plasma), a single convoluted layer based on Vulcan carbon particles (LT1600, known as a gas diffusion layer—GDL) or a double layer composed of CNFs covering a GDL. Membrane electrode assemblies (MEAs) were prepared by hot-pressing one of these three electrodes with a commercial electrode (0.5 mgPt cm−2) and a commercial Nafion 115 membrane, and compared with a reference MEA (from Electrochem Inc. with a Pt loading per electrode of 0.5 mgPt cm−2 and a maximum power density of 425 mW cm−2). The cathodic Pt utilization efficiency in the best performing plasma-prepared cathode (based on the double layer GDL/CNF) with a Pt loading of 0.1 mgPt cm−2 is 3.6 times higher than that measured for the commercial cathode (3.1 versus ). On the anode side, the three designs of plasma-prepared electrodes with 0.01 mgPt cm−2 lead to similar MEA performance than a commercial electrode at high backpressure (3 bar). At a lower backpressure, the GDL/CNF electrode is the best performing plasma-prepared anode.
FREQUENCY OF AND REASONS FOR BARGAIN PURCHASES – EVIDENCE FROM GERMANY

This study investigates the prevalence of transactions resulting in negative goodwill under IFRS 3 Business Combinations. For a sample of 1,440 firm-year observations of listed German firms for the years 2005 to 2013, we find 96 negative goodwill transactions which give rise to an immediate gain recognized by the acquirer. Besides the fact that “bargain purchases” are not as rare as assumed by the standard setter when developing the current guidance, we document the reasons for the occurrence of negative goodwill. Our findings show that “bargain purchases” indeed account for the single most disclosed reason in our sample. However, alternative reasons such as future restructuring activities or market conditions are together equally likely to explain the existence of negative goodwill. Therefore, our results question whether the current treatment of negative goodwill as an immediate gain is most appropriate.
TOPSIS Strategy for Multi-Attribute Decision Making with Trapezoidal Neutrosophic Numbers

Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is a popular strategy for MultiAttribute Decision Making (MADM). In this paper, we extend the TOPSIS strategy of MADM problems in trapezoidal neutrosophic number environment. The attribute values are expressed in terms of single-valued trapezoidal neutrosophic numbers.
An exploratory study of creativity, personality and schooling achievement

ABSTRACT We investigate the link between schooling achievement and creativity scores, controlling for personality traits and other individual characteristics. Our study is based on field data collected in a secondary school situated in a Parisian suburb. Four scores of creativity were measured on 9th graders. Verbal divergent thinking negatively predicts the grades in most subjects, but graphical integrative thinking is positively correlated with scientific grades. There is no significant correlation with the other measures of creativity, implying a low importance of creativity in school. In line with previous work, we find that conscientiousness and openness are positively associated with grades.
Family Separation and Child Welfare Protocols in Mixed-Immigration Status Immigrant Households

Purpose: The experience of immigrant families under growing immigration enforcement policies were explored to better understand the health implications that anti-immigrant policies may have on children, their families, and the wider social fabric of the immigrant community in Tucson, Arizona. This pilot study will help researchers formulate funding strategies for a more comprehensive and systematic collection of data with policy implications at a national level. Research Design: A community based participation action research approach helped researchers formulate questions and organize focus groups to capture the nuances of mixed immigration status households—domestic units in which the legal status of its members vary—a condition attributed to decades of migration in response to the U.S. demand for labor and progressive impoverishment in less developed nations. The testimonials were analyzed using qualitative content analysis. Findings: Most notable results include the remarkably high frequency of the stress variable for all groups, paralleled by a remarkably high frequency of resistance and coping mechanisms among all focus groups. Equally notable is the higher frequencies of these same variables in female-headed households compared to the other groups. Households composed of regularized immigrants or U.S. citizens were more likely to express feelings of being discriminated. More research is needed into how households are responding to greater marginalization from health care programs.
Nesting of the Common Potoo, Nyctibius griseus (Gmelin, 1789) (Aves: Nyctibiidae) in an urban environment in central Cerrado

This is a report on two nesting attempts by the Common Potoo (Nyctibius griseus) in an urban environment at Palmeiras de Goiás, Goias state, central Brazil. In December 12, 2006, a nest was found on a tree (Caesalpinia pothoroides), 2.8 m above the ground. This nest contained a white egg with dark red and brown patches. A few days later, no eggs were found in this nest. Other nesting attempt was recorded on October 9, 2007, when a chick was found in the same place used as nesting site in 2006. The young was not found in the next days. Our study is the first to document the nesting of N. griseus in the Cerrado core area. Key words: Caprimulgiformes, nest site, Cerrado, urban ecology.
Online Community and Its Impact on E-Learners' Commitment To Stay in their Programmes

Attrition rate has been found to be higher in non traditional universities compared to traditional universities. Feeling of isolation has been identified as one of the key factors that cause attrition. Thus many universities developed the Learning Management System (LMS) to increase contact hours for their learners as well as providing learning support. This tool if managed well can silently trigger the creation of an Online Community and engage learners, tutors and management staff. This paper focuses on the impact of Online Community on learners Commitment to stay in their programmes. Data analysis on 1,116 respondents from Open University Malaysia found that there was a strong correlation between the Sense of Community, Satisfaction, Motivation and their Commitment to stay in their programmes. Sense of Community, Satisfaction and Motivation explains 68 percent of their Commitment to stay. (Authors' abstract)
Viability of Calanus finmarchicus eggs in situ: does the presence of intact phytoplankton reduce hatching success?

Campbell, R. W. and Head, E. J. H. 2000. Viability of Calanus finmarchicus eggs in situ: does the presence of intact phytoplankton reduce hatching success? – ICES Journal of Marine Science, 57: 1780–1785. In order to test whether or not the presence of intact diatoms (and other phytoplankton) inhibits hatching of copepod eggs, hatching success was measured for Calanus finmarchicus eggs collected from freshly captured females incubated in filtered seawater (FSW), in natural phytoplankton mixtures (collected at the depth of the chlorophyll maximum), and in a culture of Thalassiosira weissflogii. When compared with eggs incubated in FSW, hatching success was generally the same in the natural phytoplankton mixtures, but lower for eggs incubated in the T. weissflogii culture. Hatching success was also uncorrelated with the abundance of phytoplankton available in situ. The results suggest that hatching success is generally high for eggs produced by female C. finmarchicus feeding during spring bloom conditions in the Northwest Atlantic, and also that it is not generally reduced by toxins exuded by natural phytoplankton assemblages in situ. 2000 International Council for the Exploration of the Sea
Effect of Microstructure on Atmospheric-Induced Corrosion of Heat-treated Grade 2205 and 2507 Duplex Stainless Steels

Atmospheric-induced corrosion tests under MgCl2 salt deposits were carried out on duplex stainless steel grade 2205 and 2507. As-received and 750�C heat-treated material conditions were investigated, and selected micro-structural sites targeted with salt-laden deposits to determine their corrosion response. Deposits were wetted under controlled climatic conditions at 80? C and 40% relative humidity. Observations of micro-structural attack indicated the presence of net anodic and net cathodic sites. Ferrite was net anode with respect to austenite and hence more susceptible to atmospheric-induced corrosion in both as-received microstructures. Ferrite and ferrite/austenite interfaces were selectively attacked in heat-treated grade 2205, whereas mainly primary and secondary austenite in heat-treated grade 2507. Scanning Kelvin Probe Force Microscopy and Magnetic Force Microscopy were used to obtain high-resolution information about susceptible microstructure sites.
Improving the physical and mental well-being of typically hard-to-reach men: an investigation of the impact of the Active Rovers project

Abstract Strong associations exist between physical activity (PA) levels and incidence morbidity and mortality. Evidence suggests that PA levels decline with age but incidence of sedentary behaviour is high. This paper examines the effectiveness of a PA intervention hosted by a professional football club. It explores the impact of the intervention upon mental well-being, health perceptions, and lifestyle knowledge in men often classed as hard-to-reach (HTR). Data were collected through a shortened version of the Warwick-Edinburgh Mental Well-Being Scale, and a longitudinal self-report questionnaire. Pre- and post-intervention changes were determined by a Wilcoxon signed rank test (p < .05). Data indicated that the intervention was successful in improving aspects of mental well-being amongst the male client group. The qualitative findings revealed a less successful transfer from the intervention to more casual PA engagement. Professional football clubs appear to be appropriate environments to promote physical and mental well-being. However, behaviour change away from the football club was less obvious, suggesting further research in this area is required.
Effect of episodic accretion on the structure and the lithium depletion of low-mass stars and planet-hosting stars

Following up our recent analysis devoted to the impact of non steady accretion on the location of young low-mass stars or brown dwarfs in the Herzsprung-Russell diagram, we perform a detailed analysis devoted to the effect of burst accretion on the internal structure of low-mass and solar type stars. We find that episodic accretion can produce objects with significantly higher central temperatures than the ones of the non accreting counterparts of same mass and age. As a consequence, lithium depletion can be severely enhanced in these objects. This provides a natural explanation for the unexpected level of lithium depletion observed in young objects for the inferred age of their parent cluster. These results confirm the limited reliability of lithium abundance as a criterion for assessing or rejecting cluster membership. They also show that lithium is not a reliable age indicator, because its fate strongly depends on the past accretion history of the star. Under the assumption that giant planets primarily form in massive disks prone to gravitational instability and thus to accretion burst episodes, the same analysis also explains the higher Li depletion observed in planet hosting stars. At last, we show that, depending on the burst rate and intensity, accretion outbursts can produce solar mass stars with lower convective envelope masses, at ages less than a few tens of Myr, than predicted by standard (non or slowly accreting) pre-main sequence models. This result has interesting, although speculative, implications for the recently discovered depletion of refractory elements in the Sun.
ANTIMICROBIAL ACTIVITES OF COW DUNG EXTRACTS AGAINST HUMAN PATHOGENS

Objective: For control of microbial infections and diseases, various synthetic drugs and chemical formulations are currently in use. But due to the problem of microbial drug resistance, new alternative synthetic drugs have been explored. Similarly, antimicrobial activities of so many natural products have also been explored. Methods: In this various study extracts of cow dung possessed antimicrobial property against human pathogens like Klebsiella pneumonia and Escherichia coli . Results: The Indian cow dung extracted possessed superior antimicrobial activity than other cow dung types and showed antimicrobial property against all the test microorganisms. Since cow dung and buffalo dung are abundant in nature, which make the process cost effective with processing ease and thus are a promising solution for a variety of health problems in the near future. Conclusion: The medicinal properties of these cow dung and buffalo dung can be exploited to formulate drugs for several diseases caused by antibiotic resistant pathogenic microorganisms.
Modeling Antarctic subglacial lake filling and drainage cycles

Abstract. The growth and drainage of active subglacial lakes in Antarctica has previously been inferred from analysis of ice surface altimetry data. We use a subglacial hydrology model applied to a synthetic Antarctic ice stream to examine internal controls on the filling and drainage of subglacial lakes. Our model outputs suggest that the highly constricted subglacial environment of our idealized ice stream, combined with relatively high rates of water flow funneled from a large catchment, can combine to create a system exhibiting slow-moving pressure waves. Over a period of years, the accumulation of water in the ice stream onset region results in a buildup of pressure creating temporary channels, which then evacuate the excess water. This increased flux of water beneath the ice stream drives lake growth. As the water body builds up, it steepens the hydraulic gradient out of the overdeepened lake basin and allows greater flux. Eventually this flux is large enough to melt channels that cause the lake to drain. Lake drainage also depends on the internal hydrological development in the wider system and therefore does not directly correspond to a particular water volume or depth. This creates a highly temporally and spatially variable system, which is of interest for assessing the importance of subglacial lakes in ice stream hydrology and dynamics.
The Performance of Initial Public Offerings Conditioning on Issue Information: The Case of Taiwan

This study employs the Fama-French three-factor model as well as Jensen's alpha to measure the long-run performance of IPOs in Taiwan. Our results show that the long-run performance of IPOs based on market adjusted returns or returns adjusted by market model is poor. However, the long-run performance based on Fama-French three-factor model is similar to the normal return pattern of an ordinary asset. Therefore, we conclude that the underperformance of IPOs in Taiwan is attributed to the mis-specification of the measurement model. Furthermore, we also show that the performance of IPOs in Taiwan is significantly driven by young and electronic offerings.
Inpatient's medical prescription errors

objective: To identify and quantify the most frequent prescription errors in inpatients’ medical prescriptions. Methods: A survey of prescription errors was performed in the inpatients’ medical prescriptions, from July 2008 to May 2009 for eight hours a day. results: At total of 3,931 prescriptions was analyzed and 362 (9.2%) prescription errors were found, which involved the healthcare team as a whole. Among the 16 types of errors detected in prescription, the most frequent occurrences were lack of information, such as dose (66 cases, 18.2%) and administration route (26 cases, 7.2%); 45 cases (12.4%) of wrong transcriptions to the information system; 30 cases (8.3%) of duplicate drugs; doses higher than recommended (24 events, 6.6%) and 29 cases (8.0%) of prescriptions with indication but not specifying allergy. Conclusion: Medication errors are a reality at hospitals. All healthcare professionals are responsible for the identification and prevention of these errors, each one in his/her own area. The pharmacist is an essential professional in the drug therapy process. All hospital organizations need a pharmacist team responsible for medical prescription analyses before preparation, dispensation and administration of drugs to inpatients. This study showed that the pharmacist improves the inpatient’s safety and success of prescribed therapy.
