Numerical Analysis of Flow Field in Vertical Wind Turbine at Free- Stream Turbulence Region

Air turbulence can affect the aerodynamic performance of wind turbines, and this effect is less on vertical wind turbines compared to horizontal wind turbines. In addition, vertical wind turbines have many advantages, but the literature related to their use to produce power is still small and needs to be developed. In this study, the effect of free-stream turbulence on the aerodynamic performance of Darrieus type vertical wind turbines was studied through two-dimensional numerical simulations. This performance can be observed through the power (P) and turbine power coefficient (Cp). Simulations were carried out at 5% turbulent intensity (Tu) with variations in wind speed (Uoo). The turbulent model used was the standard k-e (SKE) and k-ω SST (SSTKW). The simulation results of the two turbulent models show the suitability for the power value (P) and the coefficient (Cp) to the experimental results The simulation result error reached 0.57% for CP with the standard k-e turbulent model; 0.14% for CP with the k-ω SST model; 0.6% for P with the standard k-e model; and 0.18% for P with the k-ω SST model.
Association of platelet count and mean platelet volume (MPV) index with types of stroke

Background: Stroke is known to be the third most prominent cause of death in the developing countries and the most common debilitating neurologic disease. This study aimed to investigate the association of platelet count (PC) and mean platelet volume (MPV) index with various stroke types. Methods: This cross-sectional study was carried out on patients over the age of 18 years who presented with signs and symptoms of the first acute stroke. Exclusion criteria were underlying chronic liver or renal disease and the time more than 6 hours from symptom initiation, hematological and infectious disorders in patients. After recording of demographic data, a complete blood cell count (CBC) test was performed. Results: From 150 patients, who enrolled in the study, 54.7% of patients were males. The initial brain CT scan was normal in 13 (8.7%) patients and showed evidence of brain infarction and intracranial hemorrhage in 84 (56%) and 53 (35.3%) patients respectively. Patients with intracranial hemorrhage had significantly higher mean of MPV index than the patients with normal brain-CT scan and patients with evidence of brain infarction (p<0.001). Conclusion: The MVP index can be a predictor of the type of hemorrhagic or ischemic finding in emergency CT scan in stroke patients. This relationship may help to better understand the physiopathologic role of platelets in the development of stroke (hemorrhagic or ischemic), but will not replace cerebral computed tomography to diagnose the type of stroke, or it may not initiate treatment for hemorrhagic stroke.
Association between symptoms and severity of disease in hospitalised novel coronavirus (COVID-19) patients: A systemic review and meta-analysis

Background Symptoms of the novel coronavirus disease (COVD-19) are well known, although asymptomatic cases were also reported due to this rapidly evolving viral disease. However, there has been limited research with inconsistent findings on symptoms of COVID-19 and diseases severity. We aimed to evaluate the association between symptoms and severity of disease in confirmed COVID-19 cases by performing a meta-analysis.Methods We conducted a systematic review by searching four online databases (Medline, Web of Science, EMBASE and Cochrane library) of published studies that included symptoms of COVID-19 cases and severity of the disease between 01-Jan-2020 and 20-Apr-2020. PRISMA and MOOSE guidelines were followed, and only articles published in English were selected. We performed meta-analysis using Mantel-Haenszel random-effects model. Degree of heterogeneity among studies and quality of the selected studies were evaluated.Results Out of 153 articles identified, a total of seven articles, including 3,168 participants, met the inclusion criteria and were included. The median age of the patients was 49 years, 1818 (57.38%) were males, and 574 (18.11%) reported severe conditions. Fever was the most commonly reported symptom in the reported COVID-19 confirmed cases (87.89%, 95% CI: 83.22–81.39%), which was followed by cough, myalgia or fatigue, and less proportionally dyspnea and headache. Dyspnea was the only symptom, which was associated with severity of COVID-19 (OR 2.38, 95% CI: 1.83–3.10). Conclusions Dyspnoea was found to be associated with severity of COVID-19. People with existing respiratory illnesses, such as chronic obstructive pulmonary diseases need to be careful about the onset of such symptom and should seek medical attention.
Defective phagocytic function of induced microglia-like cells is correlated with rapid progression of sporadic ALS

Background: Microglia play a key role in determining the progression of amyotrophic lateral sclerosis (ALS), yet their precise role in ALS has not been identified in humans. The objective of this study was to identify the functional characteristics of microglia and related factors in patients with sporadic ALS that is rapidly progressing.Methods: After confirming that microglia-like cells (iMGs) induced by human monocytes could recapitulate the main signatures of brain microglia, serial comparative studies were conducted to delineate functional differences in iMGs from patients with slowly progressive ALS [ALS(S), n = 14] versus rapidly progressive ALS [ALS(R), n = 15]. Results: Despite an absence of significant differences in the expression of microglial homeostatic genes, ALS(R)-iMGs preferentially showed defective phagocytosis and an exaggerated pro-inflammatory response to LPS stimuli compared to ALS(S)-iMGs. Transcriptome analysis revealed that the perturbed phagocytosis seen in ALS(R)-iMGs was closely associated with decreased NCKAP1 (NCK-associated protein 1)-mediated abnormal actin polymerization. NCKAP1 overexpression was sufficient to rescue impaired phagocytosis in ALS(R)-iMGs. To leverage our findings and identify biological markers of rapidly progressing ALS, we measured plasma miRNA-214-3p (negative regulator targeting NCKAP1) levels. Post-hoc analysis indicated that decreased NCKAP1 expression in iMGs and a concomitant increase in plasma miRNA-214-3p levels was correlated with rapid progression of ALS.Interpretation: Our data suggest that microglial NCKAP1 may be an alternative therapeutic target in rapidly progressive sporadic ALS. In addition, miRNA-214-3p levels could be a serological biomarker for predicting the speed of disease progression.
Traumatic dental injuries and impact on quality of life of 12-year-olds in Brazil

Aims: The aim of the present study was to analyze the association between traumatic dental injuries and impact on quality of life among 12-year-olds in Brazil. Sample: 7328 12-years-old were evaluated. Study design: An analytical cross-sectional study was carried out. Place and Duration of Study: The study used secondary data from the 2010 Brazilian National Oral Health Survey. Methodology: Oral health-related impact on daily activities was assessed using the Oral Impacts on Daily Performances (OIDP) inventory. The chi-square test was used for the bivariate analysis. Results: A high prevalence rate of traumatic dental injuries was found in the male gender as well as among residents in the mid-west, north and northeast regions of the country. The OIDP score was equal to or greater than 1 in the majority of children with traumatic dental injuries, with consequent irritability or upset feelings and greater trouble brushing the teeth. These individuals also exhibited trouble practicing sports and recreational activities, felt embarrassment upon smiling and had greater difficulty regarding school activities. All these associations were statistically significant. Conclusion: Traumatic dental injuries affect the daily performances of 12-year-olds. Aesthetic concerns were greater than functional concerns in the sample study, as no statistically significant association was detected between traumatic dental injury and trouble eating.
Cytoplasmic metabolites study of Vegetative and Reproductive structures of Solieria robusta

Solieria robusta exhibits triphasic isomorphic alternation of generation. The plants of the male, female and tetrasporphytes are terete with erect lateral branches that show attenuation at their bases. The thallus is differentiated into cortex and medulla. Spermatangial mother cell and spermatangial cytoplasm stain moderately for sulphated and carboxylated polysaccharides whereas mature tetrasporangia, tetraspores, and carpospores are rich in sulphated polysaccharides. The tetrasporangial cytoplasm like carposporangial cytoplasm show fibrous vesicles, chloroplast, mitochondria and floridean starch grains. A thick electron transparent mucilaginous sheath covers the tetrasporangial wall whereas carposporangial wall is 3 to 5 layered. The carpospores and tetraspores are replete with floridean starch grains which are of various shapes and size. Solieria robusta (Greville) Kylin shows regeneration.
Scholastic Dishonesty Among Undergraduates in Differing Systems of Social Control

Extensive scholastic dishonesty was found in two large Southern universities, although not to the same extent in each. This contrast raised the question of whether the observed differences in frequency were due to different personal background characteristics of the 8tudents at the two universities, or to the different forms of social control in use at the two institutions. This investigation indicates that both types of characteristics may be related to deviation, but that social control, or collectivity characteristics are more closely associated with deviation and better explain thte differences found than personal background, or member characteristics.
Expanding the Reach. Traditional Ecological Knowledge And Technological Intensification in Beekeeping Among The Ogiek of Mau Forest, Kenya

BackgroundInitiatives for the promotion and intensification of beekeeping through the introduction of modern beehives are taking place in East Africa and elsewhere where beekeeping has been a long-standing livelihood practice. When innovations are introduced into people’s livelihoods and culture, they can trigger multiple changes, aligned or not with the original intentions. We carried out fieldwork in the Eastern part of the Mau Forest Complex, focusing on beekeeping activities among Ogiek beekeepers involved in a project aimed at promoting honey production through the modernization of the apiculture sector. The main aim of the study was to explore the relationships, tensions and complementarity of traditional and modern knowledge and practices and the ways in which they are employed in beekeeping strategies among the Ogiek, as well as to reflect on the changes that this intensification process triggers in the livelihoods of the Ogiek and in their relationship with Mau ForestMethodsWe conducted semi-structured interviews and free listing exercises with 30 Ogiek beekeepers. Other methods included guided field walks in apiaries and participant observation. We collected ethnobotanical data about the flora used in beekeeping and ethnographic information on traditional practices of apiary management and honey harvesting and storing.Results We report 66 species that are important for beekeeping purposes in 6 main use categories, namely melliferous species, and species used for making hives, placing hives, attracting bees, harvesting and storing honey. Our study reveals that the Ogiek still possess detailed knowledge of the forest’s flora and its importance and uses. At the same time, they have moved beekeeping out of the forest into open areas of pasture and crop fields, adopting modern beekeeping techniques. The two beekeeping systems have complementary roles in the livelihoods of the Ogiek and rely on different paths of knowledge transmission and on different plant species. We highlight that modern and traditional beekeeping respond to the challenges and requirements of different ecological settings.ConclusionsOur study indicates a complementarity of traditional and modern beekeeping and associated knowledge and practices within the livelihoods of the Ogiek, but it also suggests that the process of honey production intensification, by decoupling beekeeping from the forest, may weaken the relationship between the Ogiek and the forest, thus impairing the Ogiek’s role as guardians of the forest, and eroding beekeeping-associated TEK. Further studies should target the promotion of forest beekeeping via the intensification of log hive production and valorisation of forest honey and associated TEK as well as floristic diversity.
Internet-Based Distance Education Materials: Does Writing Style Matter?

How can distance educators format materials so that they maximize usability and optimize learning? Several web-writing characteristics have been identified that address these questions. “Objective” writing, most analogous to educational text, presents information without exaggerations or boasting. “Concise” and “scannable” writing omit superfluous information and support visual scanning by highlighting key features, respectively. “Combined” writing aggregates characteristics from the objective, concise, and scannable styles. Previous research suggests that, in contrast to results from the commercial domain, these writing styles do not influence memory of distance education materials. This discrepancy is possibly due to measurement differences. To address this issue, the present study employed recognition (i.e., multiple-choice) and guided recall (i.e., fill-in-the-blank) tasks in order to assess the efficacy of the writing styles in a distance education context. The results, however, confirmed the earlier findings, i.e., regardless of the material's writing format, memory for web site content was unaffected.
FORECASTING ECONOMIC TIME SERIES

The prediction of future events and developments is an exciting and perhaps mysterious task, often associated with the aura of prophets and seers instead of probabilistic models and computer screens. The reality of macroeconomic forecasting, however, is quite mundane. Predictions of macroeconomic aggregates play an important role in the decision making of private enterprises, central banks, and governments. In general, forecasts become less popular if they turn out to be inaccurate ex post, and the postwar history of macroeconomic forecasting has had its share of disappointments. For instance, in the early 1980's, economists tested inflation forecasts taken over the previous 20 years and found that the forecasts were poor, partly as a result of the oil price shocks in the 1970's. A recent study (Croushore, 1998) with data up to 1996 provides a more favorable assessment of the quality of inflation forecasts.
Effect of preoperative carbohydrate intake on inflammatory factors and clinical outcomes in elderly patients undergoing radical prostatectomy: a single-center, double-blind randomized controlled trial

BACKGROUND: To investigate the advantages of Carbohydrate (CHO) in inflammatory markers, comfort and clinical outcomes in elderly patients undergoing open radical prostatectomy.METHODS: Patients of ≥65 years old with radical prostatectomy who underwent open radical prostatectomy were randomized to the CHO group, water group, and fasted group. Patients in the CHO group and water group received oral CHO, 800 ml of placebo water before surgery, and oral CHO and placebo water 400 ml 2 to 3 hours before surgery; the fasted group did not drink any liquid. The main outcomes are inflammatory markers. The secondary outcomes are cellular immunity, comfort, the index of grip strength of body mass and clinical outcomes.RESULTS: A total of 90 patients were included in current study (i.e., CHO group, n=28; water group, n=30; fasted group, n=32). The three groups matched well in age, body mass index, the grade of (American Society of Anesthesiologists) ASA, operation time, blood loss, and fluid volume. CHO reduces IL-6 of Day1 and Day7 (P = 0.009, 0.005, respectively), IL-8 (P=0.005) of Day1, Day1, Day 3, and Day 7 TNF (P = 0.001, 0.006, 0.003 respectively) compared with the fasted group ; placebo water reduced Day 1 and Day 7 TNF (P = 0.005, 0.038, respectively), Day 1of IL-8 (P = 0.045). CHO reduced Day3 of TNF (P=0.026) compared to placebo water. In the CHO group and the water group, the morning thirst scores (0.68, 1.26, respectively) and starvation (0.24, 0.47, respectively) were decreased. The first time to leave bed in the fasted group (39.21 (15-93) h) was much later than in the CHO group (28.57 (10-100) h) and the water group (28.71 (12-70) h). Conclusion: Compared with routine water ban, preoperative CHO and placebo water can reduce the levels of IL-6, IL-8 and TNF in elderly patients undergoing radical prostatectomy, which can improve the patient's preoperative comfort and shorten the patient's first time to leave bed. Compared with placebo water, CHO has no significant advantage in improving inflammatory markers and clinical outcomes.
A Yang–Baxter equation for metaplectic ice

We will give new applications of quantum groups to the study of spherical Whittaker functions on the metaplectic $n$-fold cover of $\GL(r,F)$, where $F$ is a nonarchimedean local field. Earlier Brubaker, Bump, Friedberg, Chinta and Gunnells had shown that these Whittaker functions can be identified with the partition functions of statistical mechanical systems. They postulated that a Yang-Baxter equation underlies the properties of these Whittaker functions. We confirm this, and identify the corresponding Yang-Baxter equation with that of the quantum affine Lie superalgebra $U_{\sqrt{v}}(\widehat{\mathfrak{gl}}(1|n))$, modified by Drinfeld twisting to introduce Gauss sums. (The deformation parameter $v$ is specialized to the inverse of the residue field cardinality.) For principal series representations of metaplectic groups, the Whittaker models are not unique. The scattering matrix for the standard intertwining operators is vector valued. For a simple reflection, it was computed by Kazhdan and Patterson, who applied it to generalized theta series. We will show that the scattering matrix on the space of Whittaker functions for a simple reflection coincides with the twisted $R$-matrix of the quantum group $U_{\sqrt{v}}(\widehat{\mathfrak{gl}}(n))$. This is a piece of the twisted $R$-matrix for $U_{\sqrt{v}}(\widehat{\mathfrak{gl}}(1|n))$, mentioned above.
A study of dielectic properties of polyimide/nano-titanium/dioxide composites films

Polyimide/nano-TiO 2 composites is prepared by using in-site dispersion polymerization,the dispersion status of nano-TiO 2 was observed by transmission electron microscope(TEM). On this basis,effects of nano-TiO 2 loading on dielectric properties of the composites were studied.The results show that the corona-resistant lifetime of PI with nano-TiO 2 loading of15%is about40timeslonger than pure PI film at the electrical stress of12kV/mm.But the mass resistivity and the breakdown strength of nano-TiO 2 filled polyimide film are deteriorated with nano-TiO 2 loading,and the relative dielectric constant and the dissipation factor are increased with nano-TiO 2 loading.
DETERMINANTS OF INTEREST IN SAVING FOR STUDENTS IN ISLAMIC BANKING

Saving money is the way to regulate our finance effectively. Bank is one of the media that is considered quite effective for this activity. The development of Islamic economic make sharia banking practices increase in an innovative way. Various sharia bank products have become a choice for saving activity. The same thing happen for student. Although the interest to save is still lacking, but the use of sharia bank products is quite beneficial for their future. The purpose of this study is to analyze the factors that influence student interest in saving on Islamic banking. Multiple linear regression is an analysis technique with hypothesis testing to support its conclusions. With a coefficient of determination of 61.2%, the results of the analysis show the level of student education of the sharia economy has a significant effect compared to other variables on students' interest in saving. But simultaneously, all independent variables influence the interest in saving students in Islamic banking. This shows that education is very important for students, therefore STIE Widya Gama Lumajang should indeed provide quality teaching to students, especially in the field of Islamic economics.

Quantum revivals in free field CFT

The recent work by Cardy (arXiv:1603.08267) on quantum revivals and higher dimensional CFT is revisited and enlarged upon for free fields. The expressions for the free energy used here are those derived some time ago. The calculation is extended to spin–half fields for which the power spectrum involves the odd divisor function. An explanation of the rational revivals for odd spheres is given in terms of wrongly quantised fields and modular transformations. Comments are made on the equivalence of operator counting and eigenvalue methods, which is quickly verified.
Weather, Stock Returns, and the Impact of Localized Trading Behavior

Abstract We document by several methods that trading in Nasdaq stocks is localized, but find little evidence that cloudy weather in the city in which a company is based affects its returns. The first evidence of localized trading is that the time zone of a company's headquarters affects intraday trading patterns in its stock. Second, firms in blizzard-struck cities see a dramatic trading volume drop compared to firms in other cities. Third, the Yom Kippur holiday dampens trading volume in companies located in cities with high Jewish populations. Despite the strong evidence of localized trading, cloudy conditions near the firm's headquarters do not provide profitable trading opportunities.
Antibiotic resistance and mecA gene characterization of Staphylococcus epidermidis isolated from some hospitals in Gaza strip

Antibiotic resistance of S. epidermidis isolated from biological specimens is a global problem to public health. In this study a total of 256 S. epidermidis isolates (128 clinical isolates and 128 nasal isolates) from Gaza strip, Palestine were investigated. All isolates were tested for its antimicrobial susceptibilities and carriage of the mecAgene. Out of the 256 isolates, 184 (71.9%) were resistant to multiple antibiotics with all displaying increased susceptibility toward rifampicin (100%), doxycycline (98.4%) and vancomycin (98%). Ninety-six isolates (37.5%) were multidrug resistant (MDR) while, 99 isolates (38.7%) were mecApositive. A significant difference was demonstrated between clinical and nasal isolates. Clinical isolates were significantly more resistant for 8/12 tested antibiotics including resistance to cefoxitin (30μg) (p=0.000) and significantly (p=0.000) represents the MDR isolates while nasal isolates were significantly (p=0.000) sensitive for all tested antibiotics. No significant difference between the two groups in carrying mecA. We find that clinical isolates gain an extra-feature that qualify it to cause a disease and methicillin resistance (MR) was not mecA dependent in all MR isolates.
