Towards a CFD Model for Prediction of Wind Turbine Power Losses due to Icing in Cold Climate

April 10-15, 2016 Abstract Icing induced power losses is an important issue when operating wind turbines in cold climate. This paper presents a concept of modelling ice accretion on wind turbines using Computational Fluid Dynamics (CFD). The modelling concept works towards unifying the processes of modelling ice accretion and the aerodynamic analysis of the iced object into one CFD-based icing model. Modelling of icing and obtaining ice shapes in combination with mesh update by surface boundary displacement was demonstrated in the paper. It has been done by expressing in-cloud icing in CFD by an Eulerian multiphase model, implementing an icing module into the CFD solution and finally by surface boundary displacement also included in the CFD solution. The model has been developed using ANSYS-FLUENT and user-defined functions. The naca profile, NACA64618, has been used to illustrate the functionality of the model. Running ice accretion for different meteorological boundary conditions has illustrated the capabilities of the model and the generated ice shapes showed agreement with the literature.
Antioxidant Activity of Croton Penduliflorus (Hutch) Leaf Extract and Fractions

Croton spp. has been used medicinally in the treatment of a variety of ailments, which include cancer, constipation, and diabetes. Various parts of the plant are used in Nigeria as antimicrobial, arbortifacient, anti-inflammatory and anti-tumorigenic agents. Dried leaves of Croton penduliflorus (Hutch) was powdered, extracted and concentrated, and the aqueous fraction partitioned into dichloromethane, ethylacetate and n-butanol. The following parametes were determined, ABTS and DPPH radical scavenging activity, Free Radical Antioxidant Power, total antioxidant capacity, total phenolic and total flavonoid contents. The aqueous and dichloromethane fractions gave the highest yields, and the crude extracts exhibited a high amount of total phenol and total flavonoids. The crude extract and dichloromethane fractions showed a high scavenging activity for ABTS and DPPH, while the crude extract and its fractions demonstrate significant radical scavenging ability and antioxidant capacity which were due to the presence of phenols and flavonoids.
Comparative analysis of methods for inferring successful foraging areas from Argos and GPS tracking data

Identifying animals' successful foraging areas is a major challenge, but such comprehensive knowledge is needed for the management and conservation of wild populations. In recent decades, numerous specific analytic methods have been developed to handle tracking data and to identify preferred foraging areas. In this study, we assessed the efficiency of different track-based methods on Argos and GPS predators' tracks. We investigated (1) the consistency in the detection of foraging areas between track-based methods applied to 2 tracking data resolutions and (2) the similarity of foraging behaviour identification between track-based methods and an independent index of foraging success. We focused on methods that are commonly used in the literature: empirical descriptors of foraging effort, Hidden Markov Models (HMMs) and first passage time analysis. We applied these methods to satellite tracking data collected on 6 long-ranging elephant seals equipped with both Argos and GPS tags. Seals were also equipped with time depth recorder loggers from which we estimated an independent index, based on the drift rate and the changes in the seals' body condition, as a proxy for foraging success along the tracks. Favourable foraging zones identified by track-based methods were compared to locations where the body condition of the seals significantly increased. With or without an environmental covariate, HMMs were the most reliable for identifying successful foraging areas on both high (GPS) and low (Argos) resolution data. Areas identified by HMMs as intensively used were congruent with the locations where seals significantly increased their body condition given a 4 d metabolisation lag.
A Job Recruitment System Using Semantic Web Technology

This research presented a new job recruitment system using Semantic Web technology. First, it introduced an information model to represent a CV (curriculum vitae) by creating the CV Ontology based on exiting well-known standards such as Europortfolio Europass CV, Description of a Career, FOAF and VIVO. Second, the research designed a new business model for a job recruitment system using benefits of the proposed CV Ontology. Finally, the research implemented a prototype system based on the proposed business model and evaluated it against other popular online recruitment systems in order to prove the feasibility of the approach. In sum, the result expresses that this proposed system is quite better than others, especially in supporting RDF, supporting ontologies and vocabularies, supporting SPARQL, and enabling linked data by SPARQL endpoint. These can solve the lack of a well-defined meaning of information and enable information-sharing across job portals. Keywords— Job recruitment system, Implementation, Information Model, Linked Open Data, Ontology, Semantic Web technology, RDF, OWL.
RUNNING HEAD: Development of Bilingual False Memories Development of False Memories in Bilingual Children and Adults

The effects of withinversus between-languages (English-French) study and test on rates of bilingual children’s and adults’ true and false memories were examined. Children aged 6 through 12 and university-aged adults participated in a standard Deese-Roediger-McDermott false memory task using free recall and recognition. Recall results showed that: (1) both true and false memories increased with age, (2) true recall was higher in withinthan between-languages conditions for all ages, and (3) there were fewer false memories in between-languages conditions than within-language conditions for the youngest children, no differences for the 8and 12-yearolds, and by adulthood, there were more false memories in between-languages than withinlanguage conditions. Recognition results showed that regardless of age, false recognition rates tended to be higher in between-languages than within-language conditions. These findings are discussed in the context of models of false memory development.
Endothelial Progenitor Cells (EPCs) – clinical implications

The endothelium is responsible for the homeostasis of the cardiovascular system and other organs by producing and secreting molecular signals, activating and upgrading expression of receptors on many cell surfaces including endothelial cells themselves, a selfperpetuating condition that is accelerating with time until a specific mechanism blocks the signals. Most of the endothelial progenitor cells (EPCs) reside in niches within the bone marrow and are released only "on demand" when a certain trigger is activated – like ischemia or an increase in oxidative radicals or other inflammatory trigger is activated – recruiting them to remote areas of ischemia where they are most needed for regeneration of blood vessels. By mobilization cells from their niches the regenerative system can create new blood vessels – angiogenesis or vasculogenesis.
How to maintain the effective levels of probiotics throughout the shelf life in yoghurt: A review

Retention of probiotic functionality throughout the entire shelf life of probiotic yoghurt can be a challenge for manufacturers. The review was aimed to interpret the factors that have an influence on the growth of probiotic microorganisms in fermented dairy foods, especially in yoghurts. Compatibility between strains is important both for the manufacture and storage of the product. Inoculation with commercial and probiotic cultures results in complex interaction among strains that is advisable to consider during strain selection and setting of fermentation conditions. Processing steps like cold ripening and storage of yoghurt can represent a threat for the viability of probiotic bacteria as an adverse environment is present. The most important factors that can be a matter of concern are the presence of oxygen, low pH and cold stress. Strategies to eliminate the drawback of these conditions based on chemical and enzymatic methods and technological developments with respect to packaging. Growth is strongly influenced by ingredients involved into the food matrix. Incorporation of prebiotics can improve the viability of probiotics during manufacturing and storage of yoghurt and can contribute to the achievement and maintenance of effective cell numbers to confer beneficial effects for the host. The prerequisite of the effective use of prebiotics is their chemical stability under the applied manufacturing conditions.
Factors Associated with Home Delivery in West Pokot County of Kenya

Background. This paper sought to estimate the percentage of women who deliver at home in West Pokot County and establish the factors associated with home delivery in the area. Design and Methods. The cross-sectional survey targeted 18,174 households between the months of April and July 2013. Six hundred mothers participated in the study. Association between predictors and the place where the delivery took place was analysed by chi-square test () at 95% confidence interval. Factors with value < 0.05 were considered statistically significant. These factors were entered into multivariate logistic regression model after controlling for confounding to ascertain how each one influenced home delivery. Odds ratio was used to determine the extent of association. Results. Based on the mother’s most recent births, 200 (33.3%) women delivered in a health facility while 400 (66.7%) delivered at home. Factors associated with home delivering were housewives (OR: 4.5, 95% CI: 2.1–9.5; ) and low socioeconomic status of 10 km (OR: 0.5, 9.5% CI: 0.3–0.7; ). Conclusions. The findings of this study provide novel information for stakeholders responsible for maternal and child health in West Pokot County.
The Financial Accelerator and Market-Based Debt Instruments: A Role for Maturities?

This paper shows how the average maturity of corporate bonds can affect the transmission of shocks if financial frictions prevail. We modify a standard financial accelerator model a la Bernanke, Gertler, and Gilchrist (1999) and allow for market-based debt which has a market-determined price. Our results show that the average maturity of bonds is essential for the transmission of shocks. The dynamics are largely identical to the standard BGG model for shorter maturities, while the model behaves differently for longer maturities. In this case a prolongation channel becomes apparent which attenuates the original amplification mechanism.
COMPUTATIONAL ANALYSIS OF INTERACTIONS BETWEEN ANTI-EPILEPTIC DRUGS AND IMPORTANT PLACENTAL PROTEINS-A POSSIBLE ROUTE FOR NEURAL TUBE DEFECTS IN HUMANS

Objective: The reason behind the occurrence of Neural Tube Defects (NTDs) in pregnant women treated with certain Anti-Epileptic Drugs (AEDs) such as Carbamazepine, Valproate, Lamotrigine, Phenobarbital, etc., is not yet known. The relationship between Folic Acid intake and NTDs is not yet established. Folate receptors play a critical role in mediating placental transport of maternal folate to the foetus. Another important protein is Carnitine O-acetyltransferase that is involved in the transport of carnitine, which is much needed for foetal metabolic functions and tissue development. The objective of this study is to understand the interaction of AEDs with two important placental proteins through a docking approach to establishing a suitable explanation of AED’s role in NTD. Methods: A generic algorithm based docking was used to identify and study the mode of interactions between the drugs and placental proteins. For comparison purpose, the natural ligands of these receptors have also been included in the dataset containing AEDs. Results: Both bonded and non-bonded interactions were observed between AEDs and the crucial residues of these proteins. The drugs formed complex with these proteins with satisfactory binding energy. Some amount of Electrostatic interaction was also observed among a few pairs of protein residue and drug molecules. Conclusion: We suggest that these drug-protein associations, involving bonded and non-bonded interactions, could be a possible portal by which certain AEDs induce NTDs in the foetus. Higher interaction of Pantothenic Acid with Folate Receptor could be a mechanism through which Pantothenic Acid inhibits Valproic Acid-induced NTDs. And thus, its supplementation can specifically prevent Valproic Acid-induced NTDs. The above mechanism also explains how increased intake of Folic Acid during pregnancy can reduce the occurrence of NTDs.

Learning Theory and Equity Valuation: an Empirical Analysis

This paper tested the Pastor and Veronesi (2003) hypothesis that the market-to-book ratio (M/B) is negatively related to the number of years (age) during which a firm has had its stock traded on an Exchange. The predicted decline takes place as a result of a learning process by investors. The authors tested this implication in the U.S. market using the Fama-MacBeth (1973) methodology. In the present article a more general econometric approach is adopted, with the use of panel data and fixed-factor regressors, with data for stocks traded at the Sao Paulo Stock Exchange (BOVESPA). The evidence does not reject the Pastor and Veronesi hypothesis. Additional conjectures were tested regarding the learning process. These tests indicate that the greater availability of data on a company amplifies the effect of the age variable on the M/B ratio, implying a more accelerated learning process. This paper concludes that the evidence for the Brazilian market supports the theory that investors learn.
Anion Exchange Behavior of Some Elements in Acetic Acid- Hydrochloric Acid Media

The heavy metals contamination of soil and water has stimulated the search for soft technologies to remove these pollutants. The objective of this study is to develop a rapid and quantitative sequential separation methods of Cd(II), Zn(II), Mn(II) and Ni(II) with a strong base anion exchange resin prolite A-400 in both chloride form-RCl and acetate form-RAc. The adsorbabilities of metal ions have been studied in the presence of different acetic acid concentrations. The Kd data of metal ions were the following selectivity sequence: Cd(II) > Zn(II) > Mn(II) > Ni(II). The adsorbabilities of metal ions were slightly higher over the whole molarity range of acetic acid (0-18 M) for RCl-resin form than RAc-resin form. The addition of HCl acid to acetic acid medium markedly enhanced the sorption of many heavy metal ions on purolite A-400. Several binary separations of metal ions were achieved on the basis of their кd values. Furthermore, Langmuir and Freundlish isotherme have been described.
Equation for the Microwave Backscatter Cross Section of Aggregate Snowflakes Using the Self-Similar Rayleigh–Gans Approximation

AbstractIn this paper an equation is derived for the mean backscatter cross section of an ensemble of snowflakes at centimeter and millimeter wavelengths. It uses the Rayleigh–Gans approximation, which has previously been found to be applicable at these wavelengths due to the low density of snow aggregates. Although the internal structure of an individual snowflake is random and unpredictable, the authors find from simulations of the aggregation process that their structure is “self-similar” and can be described by a power law. This enables an analytic expression to be derived for the backscatter cross section of an ensemble of particles as a function of their maximum dimension in the direction of propagation of the radiation, the volume of ice they contain, a variable describing their mean shape, and two variables describing the shape of the power spectrum. The exponent of the power law is found to be −. In the case of 1-cm snowflakes observed by a 3.2-mm-wavelength radar, the backscatter is 40–100 times.
Busy Days: Exposing Temporal Metrics, Problems and Elasticities through Diary Studies

The study of temporal properties of people’s activities helps us to understand their needs and to assess the benefits they would gain from interactive systems. This paper describes the Busy Days study project, which employs an augmented diary study method involving eliciting a plan before the diary is kept. The plan helps in exposing not only problems, in the form of disruptions to temporal objectives and daily plans, but also the critical parameters by which the performance of supporting technologies can be measured. Analysis of the data reveals several disrupting effects, two of which (forgetfulness, overruns when writing to completion) are briefly discussed. One significant effect, the temporal elasticity of work with a tangible focus (i.e., artefacts or people), is presented. Author Keywords Performance metrics, diary studies, temporal structures, human enhancement, critical parameters.
Derivation of body motion via appropriate smoothing of acceleration data

Animal movement, as measured by the overall dynamic body acceleration (ODBA), has recently been shown to correlate well with energy expenditure. However, accelerometers measure a summed acceleration derived from 2 components: static (due to gravity) and dynamic (due to motion). Since only the dynamic component is necessary for the calculation of ODBA, there is a need to establish a robust method for determining dynamic acceleration, currently done by substracting static values from the total acceleration. This study investigated the variability in ODBA arising from deriving static acceleration by smoothing total acceleration over different durations. ODBA was calculated for 3 different modes of locomotion within 1 species (the imperial shag) and for swimming in 4 species of marine vertebrates that varied considerably in body size. ODBA was found to vary significantly with the length of the running mean. Furthermore, the variability of ODBA across running means appeared to be related to the stroke period and hence body size. The results suggest that the running mean should be taken over a minimum period of 3 s for species with a dominant stroke period of up to this value. For species with a dominant stroke period above 3 s, it is suggested that static acceleration be derived over a period of no less than 1 stroke cycle.
Fungal Diversity Cladosporiod on monocotyledon plant from Thailand

During our studies on the diverse cladosporoid species occurring on monocotyledon plants, many species of Cladosporium previously unreported in Thailand were encountered. In this paper, we report on six species of Cladosporium from various monocotyledon plants. Based on analyses of the internal transcribed spacers (ITS1, 5.8S nrDNA, ITS2) and the translation elongation factor 1–α gene (EF–1α), the isolates are members of Cladosporium cladosporiodes complex. Based on the cultural and micromorphological characteristics, they were identified as C. cladosporiodes, C. cucumerinum, C. perangusum, C. pseudocladosporiodes, C. tenuissimum and C. xylophilum. These six species represent new records in Thailand and world new host records. Keys word: Cladosporioid, Cladosporium, monocotyledon
THE IMPACT OF NEWS EVENTS ON THE TUNISIAN STOCK MARKET VOLATILITY: A POST-REVOLUTIONARY STUDY

This study examines the impact of political, economic, social and terrorism events on market volatility over the period of the Tunisian revolution from December 1, 2010 to May 29, 2015. Our study is based on daily data of three variable: Tunindex the composite index of the Tunisian stock market, the financial companies’ index, and the exchange rate Eur/Tnd, in order to detect the influence of each type of event on these three selected variables. Using an EGARCH model, the empirical evidence highlights that the fourth types of events affect the Tunindex market volatility. In fact, the political, social and terrorism events increase the volatility of the index. However, the economic events diminish this volatility. Furthermore, we notice that only political and social events influence the market volatility of the financial companies. However, exchange rate Eur/Tnd was affected only by economic and social events.
Occurrence and multilocus genotyping of Giardia duodenalis in pets and zoo animals in Shanghai, China.

INTRODUCTION High prevalence of Giardia infections occurs in humans and animals, partly because of the increasing numbers of pets. We determined the presence and genotypes of G. duodenalis in pets and zoo animals. METHODOLOGY A total of 84 specimens were collected from dogs and cats from a pet hospital, and 54 specimens from a zoo, which included deer, tigers, yaks, and others. All the specimens were examined by microscopy and by polymerase chain reaction (PCR) amplification and subsequent sequencing of glutamate dehydrogenase (gdh), beta-giardin (bg), and triose phosphate isomerase (tpi) genes. RESULTS Giardia infection was confirmed in 5.95% and 15.48% of animals by microscopy and by PCR, respectively; the detection levels were 13.33% and 26.67% for pets, and 1.85% and 9.26% for zoo animals. Four assemblages were identified: assemblage C in dogs, cats, and a sheep; D in dogs, a wolf, a yak, and a leopard; E in a sheep; and F in a cat and a leopard. PCR gave the highest amplification rate at the gdh locus. Eight, five, and four sequences were novel at the gdh, bg, and tpi loci, respectively. Two tpi sequences of dog-derived assemblage C had 100% homology with amino acid sequences from human-derived isolates. CONCLUSIONS The molecular characterization of G. duodenalis in pets and zoo animals in China is described. Assemblage D was identified in a yak and a leopard for the first time. Multilocus genotyping analysis identified the same tpi gene sequences of assemblage C in dogs and humans, indicating potential zoonotic transmission.
Exports and Economic Growth Nexus: The Case of Pakistan

This paper re-investigates the exports and economic growth nexus for Pakistan. The paper employs cointegration and multivariate Granger Causality Test [Toda and Yamamoto (1995)] to study the long-run and short-run dynamics among exports, imports, and real output growth over the 1960–2003 period. Results strongly support a long-run relationship among imports, exports, and output growth. Feedback effect between import and output growth and unidirectional causality from export to output growth was found. Nevertheless, the results do not confirm any significant causality between imports and exports.
Functional Properties of Milk‐Egg Mixtures

We used an experimental design (Scheffe simplex-centroid design) to examine ingredient interactions in food protein mixtures and their effects on functional properties. A defined and limited number of milk, albumen, and egg yolk blends were made and evaluated for heat gelation properties and for emulsifying and foaming capacity and stability. The method accounted for nonlinear interactions between the ingredients. Synergistic effects were revealed on heat gelation and emulsifying properties but antagonistic effects for foaming properties were noted.
