Vertical fluxes of nitrate in the seasonal nitracline of the Atlantic sector of the Arctic Ocean

This study compiles colocated oceanic observations of high-resolution vertical profiles of nitrate concentration and turbulent microstructure around the Svalbard shelf slope, covering both the permanently ice-free Fram Strait and the pack ice north of Svalbard. The authors present an overview over the seasonal evolution of the distribution of nitrate and its relation to upper ocean stratification. The average upward turbulent diffusive nitrate flux across the seasonal nitracline during the Arctic summer season is derived, with average values of 0.3 and 0.7 mmol m−2 d−1 for stations with and without ice cover, respectively. The increase under ice-free conditions is attributed to different patterns of stratification under sea ice versus open water. The nitrate flux obtained from microstructure measurements lacked a seasonal signal. However, bottle incubations indicate that August nitrate uptake was reduced by more than an order of magnitude relative to the May values. It remains inconclusive whether the new production was limited by an unidentified factor other than NO3− supply in late summer, or the uptake was underestimated by the incubation method.
Clinico-haematological studies on experimental Cryptosporidium parvum Jammu isolate infection in Swiss albino mice

The present study was conducted to determine the clinco-haematological effects of a well characterized Cryptosporidium parvum isolate in Swiss albino mice. Sixty female mice were divided into four groups. Group I mice served as healthy control. In group II, C. parvum oocysts were administered orally, mice of group III were given dexamethasone in drinking water whereas group IV mice were given dexamethasone along with C. parvum oocysts. Clinical signs were more severe in immunosuppressed infected mice and observed dullness, depression, inappetance, poor fur condition, progressive weakness, and decrease in body weight. In addition, mice in group IV showed profuse diarrhoea. An overall mortality rate of 7% and 20% was seen in group III and IV animals, respectively. Animals of group IV had significantly lower average body weight as compared to other groups around the time of peak infection with C. parvum which was recorded to be around 10th DPI. Based on severity of clinical disease and oocyst shedding intensity significant leukocytosis along with neutrophilia and lymphocytopenia was observed in group IV mice at 10th DPI as compared to mice in other groups. It was concluded that experimental infection with C. parvum in mice caused a severe clinical disease which peaked around 10th day and was seen to subsequently resolve around 15 DPI.

Morphological and Microsatellite Analysis of Intravarietal Heterogeneity in ‘Beneshan’ Mango (Mangifera indica L.)

'Beneshan' is the choicest table cultivar of mango (Mangifera indica L.) that has been under cultivationfor more than a century in Andhra Pradesh state, India. Through an eco-geographic survey covering thethree regions of the state, 31 accessions of 'Beneshan' (BN Acc-l to BN Acc-31) were selected and theirfruit and leaf samples were collected to study intracultivar heterogeneity based on morphological fruittraits and microsatellite markers, respectively. In-situ characterization and evaluation of fruit samplesrevealed phenotypic variations among 'Beneshan' accessions. Of the 109 mango-specific simple sequencerepeats (SSRs) validated, 23 were polymorphic. Polymorphic microsatellites produced a total of 58alleles, of which 30 were polymorphic (51.72%). The polymorphic information content values variedfrom 0.03 (SSR-59) to 0.72 (SSR-87). Highly polymorphic microsatellites like SSR-80, SSR-87, SSR-28,and SSR-89 were more useful in differentiating the 'Beneshan' accessions. Microsatellites SSR-91 andMngSSR-26 produced unique alleles of 280 and 140 bp in BNAcc-8 and BNAcc-9 accessions,respectively. Jaccard’s similarity coefficient varied from 0.50 to 1.00. There was a wide range ofintravarietal heterogeneity (up to 50%) indicating that 'Beneshan' whatsoever cultivated throughout thestate is not pure clone, which allows the genetic breeding of this cultivar by means of mass selection.
Dark Energy Survey Year 1 Results: Cross-Correlation Redshifts in the DES -- Calibration of the Weak Lensing Source Redshift Distributions

We present the calibration of the Dark Energy Survey Year 1 (DES Y1) weak lensing source galaxy redshift distributions from clustering measurements. By cross-correlating the positions of source galaxies with luminous red galaxies selected by the redMaGiC algorithm we measure the redshift distributions of the source galaxies as placed into different tomographic bins. These measurements constrain any such shifts to an accuracy of ∼0.02 and can be computed even when the clustering measurements do not span the full redshift range. The highest-redshift source bin is not constrained by the clustering measurements because of the minimal redshift overlap with the redMaGiC galaxies. We compare our constraints with those obtained from COSMOS 30-band photometry and find that our two very different methods produce consistent constraints.
RESILIENCE IN FOREIGN LANGUAGE LEARNING: A STUDY ON PRE-SERVICE TEACHERS’ LANGUAGE LEARNING EXPERIENCES

Investigating pre-service teachers’ language learning experiences is essential as they have an impact on their learning during their departmental studies and their future teaching practices. Given the fact that there is a growing call for the development of resilience in teacher education programs, this qualitative study aims at exploring what resources pre-service English language teachers have relied on to overcome challenges and obstacles to learning English as a foreign language. To achieve this aim, data were obtained from 23 pre-service teachers enrolled in English Language Teaching program at a university in Istanbul, Turkey in the form of a reflective writing activity. To triangulate data, a focus group interview was carried out with five of the participating pre-service teachers. Data were analyzed using the thematic analysis approach (Braun & Clarke, 2006). Findings revealed that pre-service teachers dealt with a variety of obstacles in their English language learning histories such as ineffective methodologies used by teachers, anxiety caused by examinations, obstacles in language skills especially speaking, and language barriers while staying in English-speaking countries. The pre-service teachers mentioned that they demonstrated agency in the process of overcoming these obstacles and their resilience included both personal protective factors and social/environmental protective factors.

Thermospheric density enhancements in the dayside cusp region during strong BY conditions

Tri‐axial accelerometer data from the Challenging Minisatellite Payload (CHAMP) satellite have revealed the thermospheric density and its variability in unprecedented detail. The data often contain regions of high density located in the cusp sector at high latitudes. In this paper we provide the first detailed explanation of a high latitude density enhancement observed by CHAMP, focusing on the August 24, 2005 interval. The Thermosphere Ionosphere Mesosphere Electrodynamics General Circulation Model (TIMEGCM) was driven by high‐fidelity high‐latitude inputs specified by the Assimilative Mapping of Ionospheric Electrodynamics (AMIE) algorithm, and reproduced the main features of the density enhancements. The TIMEGCM and AMIE provide a global framework for interpretation of the CHAMP densities. Our simulations reveal that the observed density enhancement in the dayside cusp region resulted from unexpectedly large amounts of energy entering the Ionosphere‐Thermosphere system at cusp latitudes during an interval of strong (+20 nT) BY.
Lipophilic antioxidants in edible weeds from agricultural areas

Abstract: The present paper reports the contents of individual lipophilic antioxidants in fourteen species of edible common agricultural weeds, typical of agricultural areas such as fields and orchards. Young edible green aboveground parts of weeds were analyzed for their chlorophyll, carotenoid, and tocopherol qualitative profiles and contents. To the best of our knowledge, this is the first report on the complete lipophilic antioxidant composition of the edible weeds examined in this study. The results revealed that all examined leafy plant species are good sources of lipophilic antioxidants, the richest source being Urtica dioica (255.64 mg 100 g − 1 " role="presentation"> g − 1 g − 1 g^{-1} fwt), followed by Cardamine hirsuta (159.85 mg 100 g − 1 " role="presentation"> g − 1 g − 1 g^{-1} fwt), Cichorium intybus (150.87 mg 100 g − 1 " role="presentation"> g − 1 g − 1 g^{-1} fwt), Aegopodium podagraria (146.07 mg 100 g − 1 " role="presentation"> g − 1 g − 1 g^{-1} fwt), Taraxacum officinale (123.35 mg 100 g − 1 " role="presentation"> g − 1 g − 1 g^{-1} fwt), and Capsella bursa-pastoris (117.59 mg 100 g − 1 " role="presentation"> g − 1 g − 1 g^{-1} fwt), all with higher or similar contents compared to spinach (138.72 mg 100 g − 1 " role="presentation"> g − 1 g − 1 g^{-1} fwt), proving the value of these weeds for nutrition. The shoot vegetable Humulus lupulus had the lowest lipophilic antioxidant content (22.98 mg 100 g − 1 " role="presentation"> g − 1 g − 1 g^{-1} fwt), but this was still 3.8-fold higher than that of cultivated lettuce. Although all weeds examined in our study are valuable sources of health-promoting lipophilic antioxidants, comparison with cultivated spinach revealed that the general belief that all wild edible greens are richer in lipophilic antioxidants than cultivated leafy vegetables is not valid.
Capital structure and company performance: The case of free zone companies in Ghana

The study investigates the effect of tax savings on the capital structure of free zone companies in Ghana. Using a panel regression model, the study specifically examines the determinants as well as the effect of capital structure on the financial performance of these companies. The study used data from annual reports of these companies from 2009–2012. The results of the study show that tax has a positive and significant relationship with the capital structure of the free zone companies, and even though the companies do not pay corporate tax for the first 10 years, they operate in Ghana and pay the lowest corporate tax after the first 10 years. The regression results also show that the age of the company, size, profitability and company risk are important in influencing the decisions on the capital structure of the free zone companies. Capital structure of the companies has an inverse relationship with return on asset, which measures the financial performance of these companies. The study provides useful recommendations for policy direction and to managers of these companies.

In MW-sized wind turbines, the most widely-used generator is the wound rotor induction machine, with a partially-rated voltage source converter connected to the rotor. This generator is a significant cause of wind turbine fault modes. In this paper, a harmonic time-stepped generator model is applied to derive wound rotor induction generator electrical & mechanical signals for fault measurement, and propose simple closed-form analytical expressions to describe them. Predictions are then validated with tests on a 30 kW induction generator test rig. Results show that generator rotor unbalance produces substantial increases in the side-bands of supply frequency and slotting harmonic frequencies in the spectra of current, power, speed, mechanical torque and vibration measurements. It is believed that this is the first occasion in which such comprehensive approach has been presented for this type of machine, with healthy & faulty conditions at varying loads and rotor faults. Clear recommendations of the relative merits of various electrical & mechanical signals for detecting rotor faults are given, and reliable fault indicators are identified for incorporation into wind turbine condition monitoring systems. Finally, the paper proposes that fault detectability and reliability could be improved by data fusion of some of these electrical & mechanical signals. © 2018 The Authors. Published by Elsevier Ltd.

Effect Of Gratitude In The Relationship Between Servant Leadership And Organizational Identification

Positive psychology and its organizational reflection on organizational behaviour, namely positive organizational behaviour, underlines the importance of positive forms of leadership in forming positive organizational climates. Servant leadership is one of the most important positive forms of leadership that effects positive feelings like gratitude and results in organizational identification. Moreover, gratitude can effect as a mediator in the relationship between servant leadership and organizational identification. To test the propositions, a field survey using questionnaires was conducted on 173 companies. In this study 503 usable surveys were applied. The obtained data from the questionnaires were analysed through the SPSS statistical packaged software. After the validation of measures, a series of regression analysis was conducted to test the hypotheses and to define the direction of relations. Analyses results highlighted the relationship among the servant leadership, gratitude and organizational identification. Findings have found to be consistent with the proposition that gratitude acts as a mediator in the relationship between servant leadership and organizational identification.
Strategic Orientations of Internationalizing Firms: A Comparative Analysis of Firms Operating in Technology Intensive and Common Goods Industries.

The strategic orientations of global integration and local responsiveness (the I-R framework) continue to dominate analyses of internationalization strategies and identify the basic strategy typologies of multinational enterprise. Much effort has been devoted to verify the generic strategies established within the original I-R framework but few studies have investigated their implied performance effects. In conformity with the foundations of the I-R framework we characterize the strategic orientations by their implied corporate decision structures and strategy processes and analyze their performance associations in two distinct industrial environments. The evidence from this analysis contradicts predictions in the conventional I-R framework. We explain this conundrum from a resource-based perspective as firms operating in technology intensive environments outperform when they have access to diverse multinational resources whereas firms in common goods businesses gain economies from global product standards. ___________________________________________________________________________
Patterns of change in timing of spring migration in North European songbird populations

From 1976 to 1997 passerines were mist-netted and ringed on the island of Christianso, in the Baltic Sea. Here we present analyses of phenological changes (i.e. time of arrival) for 25 species based on the entire populations of mist-netted songbirds during spring migration. We used two approaches (least square and quantile regression) to test for changes in arrival time of first individuals and three different parts of the songbird populations (i.e. first 5%, 50% and 95% of the total number of trapped individuals corrected for trapping effort). Our results generally confirm earlier spring arrival of migratory passerines with an overall earlier arrival of 0.26 days per year. Changes in the arrival time of first individuals are often the only data available. They are typically analysed on the assumption that they are representative of their respective population. We found a unidirectional, significant change towards earlier arrival for all four measures of arrival timing which seem to support this. However, the four measures of arrival are changing at different rates. First individuals changed arrival time more rapidly than the first 5%, 50% and 95% of the spring total. Such differences are likely to be important for our understanding of population-dynamic changes in relation to climate change. These differences may also have long-term evolutionary consequences. Migration distance seems to affect the degree of change in arrival time, but we found no difference between species wintering in different regions of Africa.
Combustion Properties of Biologically Sourced Alternative Fuels

Combustion Properties of Biologically Sourced Alternative Fuels Abhishek Barnwal Masters of Applied Science Graduate Department of Aerospace Engineering University of Toronto 2012 The effects of pressure on various properties of ten different syngas fueled flames were analyzed using one and two dimensional simulations. One-dimensional premixed flames were modeled in CANTERA. Flame speed, adiabatic flame temperature and thermal diffusivity as functions of equivalence ratio and pressure were quantified for the fuels using four chemical kinetic mechanisms. Data from the different mechanisms displayed good agreement with data from previous experimental benchmarks. Two-dimensional axisymmetric co-flow flames were simulated in a state of the art computational framework for modeling laminar flames. Flame structure comparisons were made with past experimental and numerical results as well as with theoretical predictions. Good agreement in stoichiometric flame height was observed with past theoretical and numerical flame height measurements. Visible flame heights had little correlation with the stoichiometric flame heights. The flame radius was also noted to be proportional to p−0.35 at high pressures instead of p−0.5 as predicted by theory.
Implication of Catering Theory of Dividend: Evidence from Financial Firms Listed on the Nigerian Stock Exchange

The increasing number of non-payers of dividend on the Nigerian Stock Exchange stimulates the interest to re-examine the determinants of payouts decisions in the market. This necessitates seeking alternative explanation for the dividend behavior of firms beyond the traditional determinants that have been established overtime. This paper examines the implication of the catering theory of dividend on the Nigerian Stock Exchange. Based on a sample of 386 firm-year observations drawn from 49 financial firms listed on the exchange, the study investigates the role of dividend premium (proxy for catering theory) and other firm level characteristics on dividend payout of the sampled firms. Panel data analysis was conducted using both fixed effect and random effect estimates. Based on the random effect estimates which is preferred by the Hausman test conducted, findings of the study shows that dividend premium have significant positive effect on dividend payout. Thus, indicating support for the catering theory of dividend. However, result indicates further that the theory is not supported during crisis. Findings also revealed that firm level characteristics which include size, profitability, cash flow, and past dividend are significant in explaining dividend payout of the sampled firms.

Swiss ball training versus stable surface training for the treatment of low back pain in male judo athletes

Background & Study Aim: Between 60% and 80% of the population suffers from low back pain at some point in their lives. This disease is commonly observed in judo, with a prevalence of around 35%. Therefore, any instrument, program or training method for the treatment of this disease is very important. Apparently, unstable surface training can be effective in reducing low back pain. However, there are not many studies that have been conducted in this regard, and the few existing ones have not opted for any particular training method. The purpose in this study is knowledge about the effect on low back pain of two different training programs, one using Swiss ball and the other with stable surface. Material & Methods: Thirty-six active volunteers, all of them judo athletes, participated in the study. They were randomly assigned to either the training group (exercising on a Swiss ball) or the control group (training on stable surface). Pain intensity was measured at the beginning and at the end of the 8 weeks in both groups by the Spanish version of the Roland Morris Disability Questionnaire (RMDQ). Results: The results of paired t test showed a significant decrease in RMDQ after treatment in both groups compared with before treatment (p<0.001), while the ANCOVA revealed no significant differences among groups on the post measurement score of RMDQ, with pre-treatment scores as the covariate. Conclusions: The training on unstable surfaces does not provide any significant improvement versus training on stable surfaces and might be at least as good as training on a Swiss ball in the reduction of low back pain for judo athletes.
Effective teaching methods in the master’s degree: learning strategies, teaching-learning processes, teacher training

The Bologna Process has substantially modified the structure of the new curricula at European universities, especially in the Masters degrees. Social and labour demands increasingly require more specialized professionals. The Faculty of Education at the University of Zaragoza implemented in the academic year 2009/2010 the Masters in Teacher Training for High School Teachersaimed at training future teachers of different degrees in the acquisition of teaching techniques and methodologies to carry out their professional work as teachers. This paper proposes objectives, methods and activities for achieving learning outcomes in the Masters compulsory module entitled "Context of Teaching Task" (CTT). The research developed has been carried out analysing students’ training needs with the main
