Structure and Transport of Atlantic Water North of Svalbard From Observations in Summer and Fall 2018

<p>The transport of warm Atlantic waters north of Svalbard is one of the major heat and salt sources to the Arctic Ocean. The circulation pathway and the associated heat transport influence the variability in the Arctic sea ice extent and the onset of freezing. We present observations obtained from research cruises and autonomous underwater glider missions in summer and fall 2018 to describe the hydrographic structure, volume transport rates and circulation patterns of the warm boundary current between 12E and 24E north of Svalbard. </p><p>A composite section is constructed along a representative, average bathymetry across the shelf break, using all available observations in order to obtain the hydrographic structure and the absolute geostrophic transport of the boundary current. The Atlantic water volume transport reaches a maximum of 3.0 &#177; 0.2 Sv in October, with an intraseasonal variability of 1 Sv. During summer and late fall, we observed Atlantic water flowing eastward (a counter current), in the outer part of the section away from the shelf break, in the Sofia Deep. The intensity of the Atlantic water counter current and the Atlantic water boundary current are very sensitive to the wind stress curl: we observed a near doubling of the volume transport in less than a week. </p><p>The composite section also reveals a bottom-intensified current flowing parallel to the boundary current, between the 1500 m and 2000 m isobaths. A composite of all historical data collected in the region, constructed identical to our observations, support the presence of the bottom intensified current. </p>
Numerical investigation of the effects of design parameters on hydraulic turbine guide vane design

Francis type hydraulic turbines that have a wide range of operating range for head and flow rates are commonly used in hydropower generation. Every power plant needs its custom designed turbine because the available head and flow rates, which are the main parameters to start the design process, are different for each plant. Guide vanes are the only movable parts of Francis turbines. They control the flow rate through the turbine. In this study, a generalized Computational Fluid Dynamics (CFD) aided design methodology is developed and applied to the design of the turbines of two different power plants. The effects of several parameters, including the shape of the guide vane profile, eccentricity, blade angles, overlapping percentage of the blades, number of guide vanes, and rotor-stator distance are examined. Results are investigated for each parameter in terms of flow physics and important outcomes are determined for turbine designers.

Ossifying Fibroma pada mandibula pasien anak

Objectives: To view a case report of mandibular ossifying fibroma (OF) in pediatric male. Case Report: A 12 year old child came to RSHS with a panoramic radiograph with the chief complaint of swelling in the right mandible. Panoramic radiograph shows well-defined mixed lesions with radiolucent content and snowflake-like opaque. MDCT shows a superior-inferior and bucco-lingual extension of the lesion. The suspicion of this case leads to Ossifying Fibroma with differential diagnosis of Adenomatoid Odontogenic Tumor (AOT) and Calcifiying Ephitelial Odontogenic Tumor (CEOT). Conclusion: OF cases in children, especially mandibular, are very rare, where the characteristics of the lesion can be well defined through the help of panoramic radiographs and MDCT. OF is a lesion that has benign characteristics with well-defined borders, and the most important lies in the presence of wrapping capsules and mixed internal structures accompanied by snowflake-like calcification.
Nonwoven characteristics effective for blood-resistant particulate filtration for healthcare application

The epidemic virus such as COVID-19 can spread via bioaerosol or droplets, and the use of filtering facepiece is crucial in reducing the opportunity of infection. For healthcare application of filters, the fluid penetration resistance is an additional benefit. In this study, nonwoven characteristics that affect the blood penetration resistance were analyzed, using different coverweb materials including electrospun and spunbond webs. The web properties were varied in the basis weight, porosity, and wettability. The blood penetration resistance was tested using the horse blood and human blood simulant at the stream velocity of 2.83 m/s. The blood resistance was affected by both the surface wettability and the physical parameters. When the coverweb and the filter web were hydrophobized, filtration efficiency against oily aerosol was enhanced, without interfering comfort properties. This study is novel in that the comprehensive effects of physical and wetting properties were investigated in terms of fluid penetration resistance, comfort properties and filtration performance.
Evaluaion of Nursing Students’ Knowledge Levels About Peripheral Intravenous Catheter Insertion Skill

Objective: Peripheral intravenous catherization procedures are frequently performed on hospitalized patients. The application of the peripheral intravenous catherization is one of the most frequently used invasive nursing procedures. Although peripheral intravenous catheterization is the most commonly performed basic nursing skill and it is the skill that causes the most anxiety during clinical practices. Thereforei this study was conducted to examine nursing students’ levels of knowledge about peripheral intravenous catheterization. Methods: This descriptive and correlational study’s data were collected from 302 nursing students from February 2019 to April 2019 during the 2018-2019 academic year. The study data were collected using an introductory information form, the Peripheral Intravenous Catheterization Information Form and in face-to-face interviews. Results: The students’ mean score for knowledge levels about peripheral intravenous catheterization was 66.53 ± 15.00. The students who had graduated from vocational schools of health and the students who were in their fourth year of study had higher levels of knowledge about peripheral intravenous catheterization, and this was a statistically significant difference with the other students. Conclusion: The nursing students’ level of knowledge about peripheral intravenous catheterization increased with years of study, and they had moderately high levels of knowledge about it during their 4-year undergraduate education.

Corporate Default Risk Modeling Under Distressed Economic and Financial Conditions in a Developing Economy

We create stepwise logistic regression models to predict the probability of default for private nonfinancial firms under distressed financial and economic conditions in a developing economy. Our main aim is to identify and interpret the drivers of private firm probability of default. For applicability and efficacy purposes, we apply a unique real-world data set of Zimbabwean private firms. Our experimental results show that the ratios of earnings before interest and tax (EBIT) to total assets, bank debt to total assets, EBIT to total liabilities, accounts receivable to net sales and the ratio of current assets minus current liabilities to total assets, the age of the firm, the real gross domestic product growth rate and the inflation rate are all strong drivers of probability of default for Zimbabwean private firms. We conclude that accounting information is useful in differentiating between defaulted and non-defaulted private firms under downturn conditions in a developing economy. Moreover, we determine that the forecasting results of probability of default models are improved by incorporating macroeconomic variables.
Comprehensive Molecular Simulation of Triple-negative Breast Cancer Transcriptomics Features of miR-145 and the 3' UTR of ARF6 mRNA

Triple-negative breast cancer is one of the deadliest diseases for women, according to the World Health Organization. The most common drugs used and in development for this disease are based upon the proteomics approach, but this so far has not accounted for the whole repertoire of human genome expression. However, a novel approach is currently under development to model the molecular interaction between miR-145 and the 3′ untranslated region (UTR) of ARF6 mRNA. This approach should eventually be useful for transcriptomicsbased drug development. The utilized methods are molecular-docking and dynamics based, using open-source software. It was found that there was a fine-grained molecular interaction between miR-145 and the 3′ UTR of ARF6 mRNA. It is concluded that the information from the interaction could be utilized as the basis for drug development.

Additionally, a key to the Stauropoctonus species and discussions on their phenology and collection methods are provided.
The Mediating Role of Entrepreneurship Behavior in the Relationship Between Social Capital and Job Performance: A study Among Faculty Members of a Medical University

Background: Job performance is an important organizational factor that plays a significant role in the success of organizations. Objectives: This study aimed to investigate the moderating role of entrepreneurial behavior in the association between social capital and job performance among faculty members of the Qazvin University of Medical Sciences. Methods: This is a cross-sectional, analytical study that is conducted using a structural equation modeling on 260 university faculty members in different schools of Qazvin University of Medical Sciences in 2017. To evaluate the causal relationships between study variables, structural equation modeling (SEM) on AMOS software, with a significant level of 0.05, was used. Results: The findings indicated that entrepreneurial behaviors and social capital are good predictors for job performance. The direct effect of social capital on job performance (path coefficient: 0.17) and its indirect effect with the moderating role of entrepreneurial behavior (path coefficient: 0.39) were confirmed (P < 0.05). Furthermore, the Sobel test affirmed the indirect associations between variables (P < 0.05). Conclusions: Strengthening social capital and promoting entrepreneurial behavior improve overall performance. Trust-building among staff and designing new motivation methods, which use entrepreneurial indicators for performance evaluation, can improve social capital. Therefore, managers can contribute to the improvement of job performance through developing entrepreneurial behavior among their employees.

Effects of shading, irrigation and mycorrhizal inoculation on growth and development of oil palm Elaeis guineensis Jacq. (Magnoliophyta: Arecaceae) seedlings in the nursery

Experiments were conducted to examine the growth and development of oil palm Elaeis guineensis Jacq. (Magnoliophyta: Arecaceae) seedlings subjected to shading, irrigation regimes and mycorrhizal inoculation in the dry season. Treatments were 2 x 2 x 2 factorial combination consisting of shade and no-shade (open sun), 7 and 14 day irrigation intervals and mycorrhizal inoculation or noninoculation. Seedlings that were grown under shade and irrigated weekly produced highest number and length of fronds, and shoot, leaf and frond weights in addition to taller plants compared to open sun (unshaded) seedlings. Across irrigation treatments, un-shaded seedlings had lower weights of leaf, frond and shoot biomass. The effects of shade treatments were significant on plant height and frond length from 2 to 20 weeks after planting. The seedlings irrigated fortnightly produced longer roots compared with the unshaded and weekly irrigated. Fortnight irrigation enhanced root development compared with weekly irrigation. Shading and weekly irrigation significantly enhanced soil moisture contents and seedling water use efficiency compared with the unshaded. Shaded seedlings irrigated weekly used larger amount of water compared with fortnight irrigation. Significant interactions were obtained between shade and irrigation regimes for most of the growth parameters measured. Mycorrhizal inoculation, shaded and weekly irrigated seedlings were more vigorous compared with the unshaded and noninoculated.
Developing climate services for Caribbean tourism: a comparative analysis of climate push and pull influences using climate indices

ABSTRACT Climate indices have a long history of use to combine multi-faceted climate information for tourism resource evaluation. Traditionally, indices have been used to assess tourists’ sensitivity to destination climatic pull factors, not tourists’ sensitivity to source market climate as a push factor for seasonality-driven markets. This study addresses this gap by using tourism climate indices to assess the influence of climatic push and pull factors for seasonal fluctuations in arrivals to Antigua and Barbuda, Barbados, and Saint Lucia, from the province of Ontario, Canada (from January 2008 to December 2017). Building on the conceptual foundation of the Holiday Climate Index:Beach (HCI:Beach), this study uses an optimization algorithm to develop two indices: (1) an optimized in-situ index that estimates the climatic pull-factor of the destination, and (2) an optimized ex-situ index that estimates the climatic push-factor from the source market. Findings reveal the optimized ex-situ (push) index explains 83% (R 2 = 0.830) of the variability in total monthly arrivals from Ontario and has greater predictive accuracy than the in-situ (pull) index. The research advances understanding of climatic influences on Caribbean tourism arrivals and provides the foundation for new seasonal forecast-based Climate Services (CS) for destination managers and marketers.
The Study of Genetics of Flower Color in Faba Bean Reveals Generous Diversity to Be Used in the Horticulture Industry

The horticulturally valuable traits of faba bean are poorly explored, including the available information on the genetics of flower color and pattern. This lack of understanding has reduced the inclusion of unique flower color into the horticultural-type faba bean market. The modes of inheritance of two flower colors (red petals and yellow spot on wing petals) were examined through the development of multiple F2 segregating populations. The inheritance of red flower was confirmed for two recessive genes and yellow wing spot inheritance was confirmed for a single recessive gene. These populations led to the discovery of combinations of red and yellow flower color that have not been previously reported. The solid wing petal color gene was confirmed as a single recessive gene. Understanding the inheritance of flower color in faba bean can lead to improvement of current vegetable types and opens up possibilities for ornamental markets.
Surface damage evaluation and computational modelling of clinically failed knee liners

ABSTRACT Five retrieved knee liners made of cross-linked, ultra-high molecular weight polyethylene were investigated. Each liner was examined by five investigators and in vivo damage was evaluated using four methods (Wasielewski, Brandt, Lombardi, and Hood). Both optical and confocal microscopy techniques were used to quantify damage modes. Oxidation index, crystallinity and hardness parameters were calculated for material characterization. Gait profiles of two subjects (one male and one female) for three different activities were considered in finite element analysis (FEA) simulations. The main hypotheses of this study were that 1) the wear tracks on the liners may be represented by maximum von Mises stress areas, 2) a single composite index may be used to represent 10 different damage modes. Significant reduction in tensile strength was observed with an average value of 27.7 MPa at 50KGy due to oxidation in all the liners. Correlations were made between FEA results and surface evaluation results. Gait analysis of the liners showed males typically have a higher stress level in vivo than females, leading to increased wear. Attempts were made to relate the damage patterns on the liners with the stress development and the damage evaluation methods and our computational simulation validates the methods that we used. Higher stress areas were compared against the surface evaluation results, showing those regions experiencing the high stress also had a high damage index. Even though the liners were mechanically intact, they failed clinically and more likely due to abrasive wear (due to third-body wear particles).
Examining the Effects of using a Porphyrios-Tree Aided Constructive Teaching Approach with Pre-service Social Studies Teachers to develop Understanding about Ecological Interspecies Relationships

This study aims to find out the effects on pre-service teachers of a constructivist teaching approach aided by use of a Porphyrios-tree. Use of a Porphyrios-tree is thought to be the basis of and most principled conceptual teaching tool to aid meaningful comprehension about concepts of interspecies relationships. The study has a quasi-experimental design and uses a single-group pre-test and post-test model. The study group consists of 3rd Grade Social Studies pre-service teachers who are studying in the Faculty of Education at a university in Turkey. The study has a two-tier application, the first of which is dedicated to conducting interviews with each participant for nearly 20 minutes in a suitable environment. Stage two is designed to conclude whether or not the responses from the individual or group interviews about the Porphyrios-tree drawings do help to resolve any misconceptions. A structured grid was used for data collection in these interviews. Data analysis was performed by analyzing the quantitative values obtained from the structured grid with SPSS 22.0. It was found out that pre-service teachers developed the most alternative conceptions in their learning about mutualism and commensalism. Also, after the application of Porphyrios-tree, the students' alternative conceptions about of “positive interaction (mutualism, commensalism)” was eliminated. More strikingly, the pre-service teachers’ post-test scores are higher in all statements of the grid. Consequently, it is recommended to carry out further research with different variables to enlighten about whether the Porphyrios-tree is an effective teaching tool in other subjects.
Applicability of Kinematic Wave Model for Flood Routing under Unsteady Inflow

This study implemented kinematic wave and dynamic wave approximation of flood routing for a prismatic rectangular channel. The results of the two methods were compared by differences in maximum flow depth, and the applicability of kinematic wave equation was discussed. The influences of hydraulic and geometrical factors on the applicability of kinematic wave equation were considered. It was found that a portion of the numerical results violated existing criteria used to indicate the applicability of kinematic wave equation, particularly when geometrical and hydraulic factors were considered together. This is because the characteristics of upstream inflow were rarely or incompletely considered in these criteria. Therefore, the present study proposed a new criterion. The theoretical influence of all factors was considered using three parameters, namely, KF02, ηts/T0′ and Qbottom/Qpeak (K, F0, ηts, T0′, Qbottom, and Qpeak represent the kinematic wave number, Froude number, the time span of discharge exceeding 90% of maximum discharge in hydrograph, wave travel time in the channel, base flow discharge, and peak discharge, respectively, while the subscript 0 represent the value of reference discharge). The influences of these three parameters were illustrated by the momentum equation of one-dimensional Saint-Venant equation. The numerical results showed that the value of ηts/T0′ (KF02)D could be used to determine the relative error ξh of kinematic wave equation. In addition, for each Qbottom/Qpeak the value of ηts/T0′ (KF02)D used to depict the same relative error ξh was different. This new criterion was validated using two real case studies, and it showed a good performance.
