An Empirical Effect of Grit on Task Performance: Mediating by Transformational Leadership and Job Involvement

This study explores the empirical effect of grit on task performance: Mediating by transformational leadership and job involvement. The research data was collected by a questionnaire through the survey method. The sample of this research is 245 lecturers selected by purposive sampling. Data analysis uses path analysis supported by descriptive statistics and correlational. The results show that grit has a positive and significant direct effect on task performance, both direct and indirect effect by mediating transformational leadership and job involvement. Thus, the lecturer’s task performance can be improved through grit, transformational leadership, and job involvement. A fit research model about the effect of grit on task performance mediating by transformational leadership and job involvement was found. This model can be discussed as a reference by researchers and practitioners in developing models of task performance in the future and any context.
Genetic Population Structure in Blue Crabs (Callinectes sapidus): High Resolution Population Genomics of a High Gene Flow Species

Widespread dispersal of progeny is expected to result in enough gene flow to maintain genetic homogeneity over large areas. Surveys of genetic markers in species with planktonic larvae have mostly confirmed this expectation. However, genetic structure has occasionally been found at small spatiotemporal scales and interpreted as evidence of restricted dispersal, natal homing, sweepstakes reproductive success, or natural selection. We investigated genetic population structure in blue crabs from the Atlantic and Gulf of Mexico coasts of North America. Sampling was most intensive from five estuaries along the coast of Louisiana, with megalopae, juveniles and adults sampled from 2010 to 2016. 1446 individuals were genotyped at 2486 SNPs in 1363 putative protein-coding loci. Levels of differentiation between locations were consistently low, but significant differentiation was found among locations and among years. No evidence was found for chaotic genetic patchiness or sweepstakes reproductive success: no genetic differentiation was detected among collections of megalopae and none of the sampled individuals were closely related. Our results indicate that gene flow in blue crabs maintains near genetic homogeneity from the northern Gulf of Mexico through the Atlantic coast of North America.

Role of antioxidant in chemotherapy related infertility

Background: Chemotherapeutic agent Doxorubicin (DOX), an anthracycline induced gonadotoxic damage has concerned physicians for decades. DOX induces damage on healthy tissues through the formation of free radicals. Vitamin C, a water-soluble non-enzymatic antioxidant was used to study its protective role on male gonads damaged by DOX. Methods: In this experimental study 30 male mice were divided into 3 groups of 10 mice each, A, B, and C. Group A was given normal saline 1 ml intra-peritoneal (IP). Group B mice were given DOX alone (0.003 mg in 0.03 ml/gm body weight IP for 3 doses on 6th, 8th and 10th day of study). In Group C, DOX (0.003 mg in 0.03 ml/gm body weight IP for 3 doses on 6th, 8th and 10th day of study) was given and Vitamin C (0.5 mg in 0.01 ml/gm body weight per orum daily was added to medication. On completion of experiment, epididymides dissected along with testes from sacrificed animals and were placed in Petri dish containing 5 ml saline and left for a few minutes for spermatozoa to float. Neubauer chamber was used for sperm count. Results: The DOX administration significantly decreased (p<0.001) number and motility of sperms as compared to controls. However co-administration of Vitamin C with DOX significantly reduced (p<0.001) the seminiferous epithelial damage. Sperm parameters seemed to be improved as compared to DOX only and control group respectively. Conclusion: Vitamin C has protective role against DOX induced testicular damage.

A 2D graphical representation of DNA sequence based on dual nucleotides and its application

From the perspective of the neighboring dual nucleotides, we introduce a novel 2D graphical representation of DNA sequences based on the magic circle, which correspond to 16 dual nucleotides. So, we can reduce a DNA sequence into a plot set in two-dimensional space and get a two-component vector relatively to the introduced covariance matrix. The utility of our approach can be illustrated by the examination of similarities/dissimilarities among the complete coding sequences of β-globin gene belonging to 11 species. © 2008 Wiley Periodicals, Inc.

Testing Liquidity Augmented Fama-French Five-Factor Model in Pakistan Stock Exchange

This study examines the empirical evaluation of the six-factor asset pricing model that augments the Fama-French (2015) five-factor asset pricing model with liquidity factor. Using data from July 2010 to June 2017 of non-financial firms listed on PSX, a 2x3 sort approach is used to construct six left-hand side portfolios, and a 2x2 approach is used to construct right-hand side factors namely, SMB, HML, RMW, CMA, and IML. Time series regression is used to analyze the data to obtained results. The empirical evidence illustrates that in PSX the six-factor model has efficient and better outcomes. Furthermore, the liquidity factor has a strong role in improving the performance of the asset pricing model.
Effect of isoniazid preventive therapy on pulmonary tuberculosis activity in people living with HIV/AIDS at Wangaya hospital in Denpasar, Bali, Indonesia: a prospective cohort study

Open access: www.balimedicaljournal. org and ojs.unud. ac.id/index.php/b j Effect of isoniazid preventive therapy on pulmonary tuberculosis activity in people living with HIV/AIDS at Wangaya hospital in Denpasar, Bali, Indonesia: a prospective cohort study Ketut Suryana1*, Hamong Suharsono2, Jarwa Antara1, Ida Bagus Ngurah Rai3 Background: Isoniazid Preventive Therapy (IPT) can reduce the Active Pulmonary Tuberculosis (APT) in People living with HIV/AIDS (PLWHA). IPT is recommended by the World Health Organization (WHO). It has not been implemented routinely in all countries. Aim: To evaluate whether IPT in PLWHA reduces the APT at Wangaya Hospital, in Denpasar, Bali, Indonesia. Methods: A prospective cohort study was conducted during October 2014 until November 2016. A total of 244 PLWHA were included in this study. The first group were 122 participants received antiretroviral therapy (ART) and IPT and 122 participants received only ART (second group). Cox regression analysis was employed to calculate effects in both groups and to identify predictor factors for active tuberculosis. The statistical analysis performed with cox proportional hazard model. Results: There were 137 (56.1%) males and 107 (43.9%) females. Incidence of APT in the IPT group was 1.09 per 100 person years and non IPT groups was 12.57 per 100 person years. Incidence of APT in the non IPT groups was significantly higher than in the IPT groups with crude hazard ratio (cHR) of 12.59 (95% CI: 2.70-53.43). After variables adjustment for age, sex and CD4 count, the incidence of APT in the non IPT group were found with adjustment hazard ratio (aHR) of 10.26 (95% CI: 2.15-48.99). Conclusion: The incidence of APT was significantly higher in the non IPT group than in the IPT group.
Production of active lipase by Rhizopus oryzae from sugarcane bagasse: solid state fermentation in a tray bioreactor

Summary This study deals with production of lipase in solid state fermentation by Rhizopus oryzae from sugarcane bagasse. A tray bioreactor was designed for the extracellular enzyme production. Daily, lipase production was evaluated at several incubation temperatures. Furthermore, the influence of temperature and humidity of the cabinet, depth of solid bed, particle size, initial moisture content and supplementary substrate (olive oil) as carbon source was investigated. The obtained results showed that bioreactor temperature of 45 °C, humidity of 80%, solid bed depth of 0.5 cm, particle size in the range of 0.335–1 mm, substrate initial moisture content of 80% for the top tray and 70% for the middle tray and supplementary substrate of 8% (v/w) olive oil led to maximum lipase production. Under optimum fermentation conditions after 72-h incubation, maximum lipase activities for the top, middle and bottom trays were 215.16, 199.36 and 52.64 U gds−1, respectively.
The Influence of Carrier on the Critical Phenomena in CO Oxidation over NiO

The influence of thermo-exfoliated graphite (TEG) on the catalytic activity of nickel in the CO oxidation process has been investigated. It was shown that nickel supported on the thermo-exfoliated graphite surface was more active catalytically than the bulk metal. Alternate oxidation–reduction on the Ni–NiO phase boundary occurred at temperatures higher than 633 K (Curie temperature of pure nickel). Using a magnetogravimetric method, it was found that the nickel catalyst was transformed by the reaction mixture into a heterophase (Ni/NiO) system both in the presence of a carrier and in its absence. Hence the carrier did not influence the size of the Ni particles. The high catalytic activity of the catalyst supported on graphite may be explained by an increase in the number of Ni particles. Ni/TEG and Ni/NiO samples were studied via X-ray diffraction, Auger spectroscopy and electron microscopy methods.
A nanocluster design for the construction of artificial cellulosomes

We describe here the construction of artificial cellulosomes by nanoclustering recombinant cellulolytic modules on non-cellulosome-derived scaffolds. Catalytic and cellulose-binding domain modules derived from cellulosomes were assembled on streptavidin and on inorganic nanoparticles. Heteroclustering of the modules significantly promoted the activity of the assembled catalytic modules for degradation of water-insoluble substrates.
The Effect of Customers Concentration on Company Risks

The companies with major customers can supply a considerable source of cash flows by selling a large portion of their products to them. Since the lack of purchase, loss, or bankruptcy of major customers can result in a significant reduction in cash flows in the company, thus the risk is the companies with major customers is higher than other companies. Thus, the present study aimed to investigate the effect of customer concentration on company risks. For this purpose, the effect of customer concentration on three criteria of stock price crash risk, bankruptcy risk, and employment risk was studied. The research sample included 127 companies listed in the Tehran Stock Exchange during 2011-2018. Multivariate regression models with panel data were used by the random-effects method to test the research hypotheses. The research findings indicated that customer concentration has a significant positive effect on stock price crash risk, bankruptcy risk, and employment risk. In other words, stock price crash risk, bankruptcy risk, and employment risk are higher in the companies where the concentration of major customers is higher.
Screen-printed enzyme electrode for the determination of lactose

An amperometric lactose sensing electrode based on thick-film technology was developed. The biosensor was based on β-galactosidase and glucose oxidase co-immobilized by cross-linking with glutaraldehyde onto the working electrodes. The enzymically generated H2O2 was monitored at 600 mV versus an Ag–AgCl reference electrode. The assay buffer was of great importance for the sensor response. Potassium citrate buffer (pH 7.0) was found to supply the best results. The buffer had to include magnesium ions, because these activate β-galactosidase. Compared with buffers without magnesium, the response increased approximately four times. The sensor showed linearity over the concentration range 2 × 10–6–2.5 × 10–3 mol l–1(correlation coefficient, r= 0.99922). Under optimum conditions, the sensor was stable for approximately 3 months without noticeable loss of activity. The lactose sensor was used in a batch system in order to determine the lactose content in milk and various dairy products. No interferences could be detected during the measurement of real samples and no sample pre-treatment was necessary. Sensor data for the determination of lactose were compared with those obtained by the Boehringer Mannheim test-kit method (ultraviolet method)(r= 0.9827, n= 26). The sensor method had a low relative standard deviation (8.81%, n= 16).
A Novel Method for Producing Spatially Uniform Aerosols in a Low Pressure Environment

Aerosols flowing in a tube under vacuum conditions, e.g., in semiconductor processing equipment, are often found to have a nonuniform profile due to low Reynolds number flow (Bae et al. 1998). A novel method to produce spatially uniform aerosols in a flow tube at low pressure has been developed. The method employs a counter-flow injection configuration. Two identical critical orifices of 200 w m in diameter are installed opposite each other in an aerosol mixing chamber. The opposing aerosol jets from the two orifices result in turbulent and uniform mixing of the two aerosol streams. Aerosols 0.3 w m or less in diameter, at a pressure as low as 1 Torr, are shown to be distributed uniformly over a cross section of a tube with an inner diameter of 3.48 cm. This method has been further improved to provide spatially uniform aerosols at lower pressures by using a pressure reducer downstream of the aerosol mixing chamber. The arrangement provides spatially uniform aerosols at a pressure as low as 0.2 Torr.
Stability of gas hydrates

Molecular dynamics computer simulations have been used to examine the validity of the assumptions upon which the cell theory of gas hydrates is based. It was found that one of these approximations-that the free energy of the water crystal is unaffected by the presence of guest molecules in the interstices of its lattice structure-is inappropriate for gas hydrates. On the basis of our calculations it is conjectured that kinetic effects may be more important than thermodynamic considerations in predicting the conditions under which gas hydrates may be expected to form
Synthesis and Rheological Properties of Long-Chain-Branched Isotactic Polypropylenes Prepared by Copolymerization of Propylene and Nonconjugated Dienes

Long-chain-branched isotactic polypropylenes (LCBed PP) were synthesized by copolymerizing propylene with a small amount of nonconjugated α,ω-diene (1,9-decadiene or 1,7-octadiene) using the catalyst system of rac-Me2Si(2-MeBenz[e]Ind) 2 ZrCl 2 (MBI)/MMAO. In this approach, the LCB structures were introduced by the incorporation of in situ generated macromonomers with pendant 1-octenyl or 1-hexenyl groups during the polymerization. A detailed study on the effects of diene concentration on polymer properties was conducted. Polymer chain microstructures were characterized by 13 C NMR, GPCV, and DSC. In the propylene/1,9-decadiene copolymerization, a series of LCBed polymer samples with the long-chain-branch density (LCBD) of up to 0.53 branch structures per 1000 carbons were produced with the diene concentrations of 0.177-3.54 mmol/L at 40 and 25 °C. A diene concentration of 35.4 mmol/L yielded cross-linked polymer gels. In the copolymerization of propylene and 1,7-octadiene, in addition to a small fraction of LCB structures produced, a cyclic seven-member ring structure was observed due to the cycloaddition of 1,7-octadiene. The cyclization significantly decreased the LCBD in the polymers. A small-amplitude oscillatory shear flow measurement was conducted to evaluate the rheological properties of the LCBed polymers. Compared to the linear samples prepared at the same polymerization conditions, the LCBed polymers exhibited enhanced low-frequency complex viscosity, improved shear-thinning, increased dynamic moduli, and reduced phase angle. The samples also showed thermorheological complexity and enhanced activation energy at low frequencies. These particular properties are related to the LCB in the polymers and become more significant with the increase of LCBD. The LCBed polypropylenes were also blended with their counterpart linear samples and demonstrated the improvement of rheological properties.
Psychological suffering, medicalization and women: a perspective of Institutional Ethnography

Background Recent years have seen a growing psychological suffer in women attended in primary health care in developing countries. This paper aims to analyze the psychological suffering in a small city in northeastern Brazil and its relationship with medicalization from the perspective of Institutional Ethnography (IE). Methods We applied 202 SRQ-20 questionnaires in the first research step. In the second step, four women were interviewed in the primary health care service.Results The results demonstrated a high number of primary health care users in psychological suffering (47.02%). The data also point to a significant prevalence of women in psychological suffering, the use of medicines and the struggles in dealing with the difficulties of everyday life.Conclusions The medicalization of psychological suffering appeared several times in this study through the invisibility of these sufferings under the blanket of biomedical and medicalizing discourse. Those facts can affect contemporary women and the contradictions of being a woman in a capitalist and patriarchal society.
Darstellung, Schwingungsspektren und Normalkoordinatenanalyse von Cs2[RhCl5(H2O)] und trans-Cs2[RhCl4Br(H2O)]†

Aus wasrig saurer Losung von [RhCl6]3− fallt nach dem ersten Hydrolyseschritt in Gegenwart von Cs+-Ionen nahezu quantitativ Cs2[RhCl5(H2O)], aus [RhCl5Br]3−-Losung stereospezifisch entstandenes trans-Cs2[RhCl4Br(H2O)] aus. Die orangenen Cs-Salze dieser Monaquo-Komplexe losen sich nur masig in Wasser und sind in organischen solventien unloslich. Die entsprechend der Punktgruppe C4v getroffene Zuordnung der IR- und Raman-Spektren wird durch eine Normalkoordinatenanalyse auf der Grundlage eines allgemeinen Valenzkraftfeldes bestatigt. Die beobachteten und berechneten Frequenzen stimmen sowohl im Valenz- als auch im Deformationsschwingungsbereich gut uberein. Als Folge des in der Reihe H2O, Cl−, Br− zunehmenden trans-Einflusses sind die Bindungen der dem Wasser gegenuberstehenden Liganden gefestigt. Die Valenzkraftkonstante der axialen RhCl-Bindung ist um 10% groser als die der aquatorialen in Cs2[RhCl5(H2O)], die von RhBr in Cs2[RhCl4Br(H2O)] liegt um 25% uber der in [RhBr6]3−. Preparation, Vibrational Spectra, and Normal Coordinate Analysis of Cs2[RhCl5(H2O)] and trans-Cs2[RhCl4Br(H2)] In a first step of hydrolysis of [RhCl6Br]3− in aqueous acidic solution [RhCl5(H2O)]2− and stereospecifically trans-[RhCl4Br(H2O)]2− are formed nearly quantitatively, precipitating in presence of Cs+ ions. The orange Cs-salts of the monoaquo complexes are slightly soluble in water and insoluble in organic solvents. The IR and Raman spectra are completely assigned according to point group C4v, supported by normal coordinate analysis based on a general valence force field. The observed and calculated frequencies are in good agreement for the stretching and deformation vibrations. The trans-influence increases in the series H2O, Cl−, Br−. The valence force constant of the axial RhCl-bond exceeds that of the equatorial bonds in Cs2[RhCl5(H2O)] by 10%, the RhBr valence force constant in tr. -Cs2[RhCl4Br(H2O)] that of [RhBr6]3 by 25%.
Shelf‐life characteristics of fresh oysters and ground beef as affected by bacteriocin‐coated plastic packaging film

Fresh oysters and ground beef were wrapped in antimicrobial films coated with a bacteriocin (nisin or lacticin NK24) incorporated into a polyamide binder layer. The packaged foods were stored at 3 and 10 C and changes in counts of total aerobic bacteria and coliform bacteria were monitored together with appropriate quality attributes in order to determine the influence of the bacteriocincoated films on quality preservation and shelf-life extension. Compared to plain low-density polyethylene film, plastic films with incorporated bacteriocins slowed down microbial growth on packaged oysters and ground beef at both temperatures, contributed in some degree to the preservation of chemical quality and extended shelf-life significantly. The effects of the antimicrobial films on the suppression of coliform bacterial growth were more pronounced at 10 than at 3 °C, while the effects on total aerobic bacteria were consistently evident at both temperatures. There was no difference in food quality preservation between the two types of antimicrobial film. Dans cette etude, des huitres fraiches et de la viande de boeuf hachee sont emballees dans des films antimicrobiens contenant une bacteriocine (nisine ou lacticine) incorporee dans une couche de liant polyamide. Les produits emballes sont entreposes a 3 et 10°C et controles en bacteries aerobies et coliformes. Les films antimicrobiens reduisent la multiplication microbienne sur les huitres et la viande hachee pour les deux temperatures d'entreposage testees.
