Genetic variability and field performance of some sweet gourd ( Cucurbita moschata Duch ) accessions Most

For Any Information: ask.author@journalbinet.com The experiment was conducted at the field and laboratory of “Collection, Evaluation, Conservation and Utilization of Landraces and Wild relatives of Some Important Vegetables and Fruits in Bangladesh (CVFB)” project, Department of Horticulture, Bangladesh Agricultural University, Mymensingh. Studies on field performance and genetic variability of sweet gourd accessions were carried out using morphological traits. Analysis of variance for different characters showed high degree of variation among the 43 accessions. The accession CM152 showed the best performance in respect of yield per plant (57.8 kg). The highest average fruit weight (10.43 kg) was recorded in CM154. Regarding the number of fruits per plant, CM145 produced the maximum number of fruits per plant (10.0). In all the traits genotypic coefficient of variation was smaller than phenotypic coefficient of variation. High heritability with genotypic and phenotypic coefficient of variation was observed for vine length at final harvest, number of male flowers per plant, node for first male flowers, average fruit weight, fruit cavity length and breadth, dry weight of 100 g flesh and number of seeds per fruit indicating additive gene effects of these traits.

Time-dependent coupling of solar oscillations

We investigate the effects of a large-scale time-dependent flow in the solar convection zone on the solar p -mode oscillations. The theory of time-dependent perturbations is applied, and we concentrate on flow fields that can be described by a single harmonic in space and time. An iterative method of obtaining approximate analytical solutions to the equations of the coupled oscillator is outlined. Example calculations are presented for the special case of two coupling partners. Special attention is paid to the resonance that occurs when the time dependence of the flow meets the beat frequency of two p modes. We conclude that time-dependent flow fields in the solar convection zone may diminish the height of the peaks in the oscillation power spectrum, and may contribute to their asymmetry, broadening, and effective shift.
Managing tensions in academic writing for foundation learners

This paper presents an analysis of a professional development initiative to promote sustainable literacy initiatives in our institution (Piggot-Irvine et al., 2010). We undertook an action research project to examine the effectiveness of our teaching of a writing assessment in two different semester cohorts. ‘Academic Study Skills for Nursing’ aimed to help students seeking entry into a nursing programme to develop the necessary strategies and tools for managing academic study at degree level. However, it was our experience that our students do not ‘seamlessly’ receive the skills our course was initially designed to teach. This paper outlines literature relating to writing in higher education and compares the results of two cohorts, one receiving instruction from a ‘study skills/ academic socialisation’ perspective and another receiving instruction from an ‘academic literacies’ perspective that explicitly acknowledges the tensions students must learn to manage in academic writing. Changes made to our teaching of a report writing assessment followed an academic literacies perspective that views writing as a process of meaning-making and the contestation around meaning, rather than learning compartmentalised skills (Carstens, 2012, p. 12). Our findings challenge a normative discourse of literacy acquisition that privileges a technical and linear model which positions nontraditional students’ literacy practices as deficit (Coleman, 2009).
The preoccupation with thresholds in cases of child death or serious injury through abuse and neglect

Thresholds into and between services emerged as a significant theme in the biennial analysis of cases of child death and serious injury through abuse and neglect ‘serious case reviews’ carried out in England for the (then) Department for Education and Skills between 2003–05. The preoccupation with thresholds was one of a number of interacting risk factors and many children's cases were on the boundary of services and levels of intervention. In most cases child protection did not come ‘labelled as such’ which reinforces the need for all practitioners, including those working with adults to be alert to the risks of significant harm. Policy makers should acknowledge that staff working in early intervention are working within the safeguarding continuum and not in a separate sphere of activity. The emotional impact of working with hostility from violent parents and working with resistance from older adolescents impeded engagement, judgement and safeguarding action. In the long term neglect cases that were reviewed, the threshold for formal child protection services was rarely met and some agencies and practitioners coped with feelings of helplessness by adopting the ‘start again syndrome’. Adequate resources are essential but not sufficient to redress the problems. Effective and accessible supervision is crucial to help staff to put into practice the critical thinking required to understand cases holistically, complete analytical assessments, and weigh up interacting risk and protective factors.

Leisure Time Physical Activity and Sleep Predict Mortality in Men Irrespective of Background in Competitive Sports

Introduction: Physical activity and sleep are closely related behaviors with suggested synergistic influence on cardiovascular health. Physical activity potentially modifies associations between sleep and mortality. Our aim was to study the interrelationships between sleep, leisure-time physical activity (LTPA), a history of sports, and mortality. Methods: A prospective cohort of former elite male athletes (n = 1,028), and age- and region-matched nonathlete men (n = 610) completed a health questionnaire in 1985. Their mortality was followed up until December 31, 2011. Analyses included Cox proportional hazards models with sleep duration and sleep quality as main predictors of all-cause and cardiovascular disease (CVD) mortality. Results: Sleep duration or sleep quality were not independently associated with mortality after controlling for socioeconomic and lifestyle factors. The interaction between sleep duration and LTPA was significant, with higher risk of all-cause and CVD mortality if sleeping 6 hours or less and not achieving 450 metabolic equivalent minutes LTPA weekly, as compared with sleeping 6.5–8.5 hours and achieving 450 metabolic equivalent minutes of LTPA. Also, the relative excess risk due to interaction between short sleep and low LTPA was significant for CVD mortality. Discussion: Significant interactions between sleep duration and LTPA with regard to mortality were observed. In particular, short sleep and low LTPA jointly predicted all-cause and CVD mortality irrespective of a history of sports. Findings suggest important synergistic associations of short sleep and low LTPA with CVD mortality risk.
Structural characterization of pressure-induced amorphous silicon

We investigate the structure and mechanical properties of pressure-induced PI amorphous silicon a-Si and compare this to the more extensively characterized case of a-Si created by ion implantation. To study the effect of thermal history we also examine the structure of both PI and ion-implanted a-Si after a lowtemperature “relaxation” anneal 450 ° C. Indentation testing suggests that structural changes are induced by thermal annealing. As-prepared forms of a-Si deform via plastic flow, while relaxed forms of a-Si transform to high-pressure crystalline phases. These structural changes are confirmed by more explicit measurements. Raman microspectroscopy shows that the short-range order as expressed by the average bond-angle distortion of the as-prepared amorphous phases is the same and reduced by the same amount following the lowtemperature anneal. Fluctuation electron microscopy demonstrates that the as-prepared PI a-Si displays a much lower variance of the diffracted intensity, a feature directly correlated with the medium-range order, than the as-prepared ion-implanted a-Si. However, relaxation brings this variance of the two networks to the same intermediate level. The mechanical tests and structural probes indicate that annealing the amorphous silicon network can bring it to a common state with the same structure and properties regardless of the initial state. This final state might be the closest attainable to the continuous random network model.
Users’ Perceptions towards Website Quality and Its Effect on Intention to Use E-government Services in Jordan

The aim of this study was to investigate users’ perceptions towards website quality and to identify the effect of this perception on their intention to use e-government services in Jordan. Data were collected using questionnaires distributed to citizens who were actual or potential users of e-government services in Jordan. The collected data were analyzed using descriptive statistics and structural equation model (SEM) to test the study hypotheses using AMOS 16.0. The results from this study revealed that among the study’s constructs (system quality, service quality and information quality respectively) had positively affected users’ intention to use services provided by the e-government in Jordan. This indicated that designers of e-government websites should take into considerations these constructs when designing e-government websites because they affect users’ intentions to use and consequently increase the success of e-government initiatives.
Climate Change and Natural Disasters

Intense climate-related disasters—floods, storms, droughts, and heat waves—have been on the rise worldwide. At the same time and coupled with an increasing concentration of greenhouse gases in the atmosphere, temperatures, on average, have been rising, and are becoming more variable and more extreme. Rainfall has also been more variable and more extreme. Is there an ominous link between the global increase of these hydrometeorological and climatological events on the one side and anthropogenic climate change on the other? This paper considers three main disaster risk factors—rising population exposure, greater population vulnerability, and increasing climate-related hazards—behind the increased frequency of intense climate-related natural disasters. In a regression analysis within a model of disaster risk determination for 1971–2013, population exposure measured by population density and people’s vulnerability measured by socioeconomic variables are positively linked to the frequency of these intense disasters. Importantly, the results show that precipitation deviations are positively related to hydrometeorological events, while temperature and precipitation deviations have a negative association with climatological events. Moreover, global climate change indicators show positive and highly significant effects. Along with the scientific association between greenhouse gases and the changes in the climate, the findings in this paper suggest a connection between the increasing number of natural disasters and man-made emissions of greenhouse gases in the atmosphere. The implication is that climate mitigation and climate adaptation should form part of actions for disaster risk reduction.
An Empirical Investigation of Chinese Award-Winning TV Advertisements over Time

This paper aims to explore the changing nature of advertising by both local and foreign brands used in award-winning Chinese TV commercials over time. The study finds competing evidence of both greater westernization and greater localization. Comparatively, foreign brands use more western symbols and appeals than local brands. Moreover, types of appeals used by durable products tend to differ from those used by non-durable products. By examining advertising appeals over two time periods, this paper captures advertisers’ adjustments to changing market and competitive conditions. These findings offer important managerial insights to advertising practitioners that operate in China.
Edge Detection in UAV Remote Sensing Images Using the Method Integrating Zernike Moments with Clustering Algorithms

Due to the unmanned aerial vehicle remote sensing images (UAVRSI) within rich texture details of ground objects and obvious phenomenon, the same objects with different spectra, it is difficult to effectively acquire the edge information using traditional edge detection operator. To solve this problem, an edge detection method of UAVRSI by combining Zernike moments with clustering algorithms is proposed in this study. To begin with, two typical clustering algorithms, namely, fuzzy -means (FCM) and -means algorithms, are used to cluster the original remote sensing images so as to form homogeneous regions in ground objects. Then, Zernike moments are applied to carry out edge detection on the remote sensing images clustered. Finally, visual comparison and sensitivity methods are adopted to evaluate the accuracy of the edge information detected. Afterwards, two groups of experimental data are selected to verify the proposed method. Results show that the proposed method effectively improves the accuracy of edge information extracted from remote sensing images.
An Estimation of Variances and Factors in Mathematics Attainment in Upper-Primary Schools

This study aimed at identifying variances related to school and pupil levels, and the performance indicators measuring the learning progress in mathematics. A longitudinal design was carried out and the stratified random sampling was used to obtain a sample of 5118 pupils from 60 primary schools. In each school three upper grades were selected, including their 180 class teachers and 60 headteachers. The data collection was carried out through questionnaires and school archives. Using multilevel analysis, the results showed that the proportion of total variance in pupil attainment for mathematics at the school level ranged from 20 to 29 per cent. When intake characteristics were taken into account as the baseline, the variance proportions were less than the prior attainments. Occupation and education of parents, besides reading facilities at home were significant explanatory variables for children progress in mathematics achievement. The outcomes have important consequences for school effectiveness research in determining the baseline and performance indicators.
A novel method for indexing and restructuring search results with Feedback Sessions

Data Mining refers to extracting or "mining" knowledge from large amounts of data. It is also called as knowledge mining from data. Search engine is one of the most important applications in today's internet. Users collect required information through the search engine in the internet. Generally a query given to the search engine can have different meaning for each user. i.e., each user has different search goals for the given query. The understanding of these different search goals helps in providing better results to the user. Firstly, different user search goals are identified with the help of the feedback session. Feedback session is one in which the last URL is the clicked one. Secondly Feedback sessions are converted to the binary vector which can efficiently reflect user information needs. Index Terms—Binary vector, Data mining, Indexing, Restructuring search results, User search goals.
Review of the tropical Southeast Asian Ephemera (Ephemeroptera: Ephemeridae)

The genus Ephemera Linnaeus, the type genus of the family Ephemeridae and the order Ephemeroptera, began to be studied as early as in the nineteenth century, but the East Asian species of Ephemera remained poorly understood. In this paper, 16 Ephemera species from tropical Southeast Asia are reviewed and descriptions of new or poorly known species and life stages, synonyms, reference sources, type information, taxonomic remarks, a male adult key to the species, and a tabulated checklist of the species are provided. Ephemera mccaffertyi sp. n. from Malaysia is described. Ephemera hainanensis Zhang, Gui & You, E. rufomaculata Zhou & Zheng, and E. spilosa Navás are redescribed. The larval stage of E. hainanensis and E. spilosa are described. Ephemera innotata Navás, E. javana Navás, E. longiventris Navás, and E. quadrigutata Lestage are assigned as nomina dubia. As a result of this study, four species from Vietnam, four species from Myanmar, two species from Thailand, one new species from Malaysia, and three species from Taiwan have been identified as members of the genus Ephemera.
Field Analysis of Dielectric Waveguide Devices Based on Coupled Transverse-Mode Integral Equation - Mathematical and Numerical Formulations

We propose an integral-equation formulation for analyzing EM field of 2-D dielectric waveguide devices. The complex 2-D device is first divided into slices of 1-D horizontally layered structures. The entire EM solutions are determined by transverse field functions on the interfaces between slices. These functions are governed by a system of integral equations whose kernels are constructed from layer modes of each slice. These unknown tangential field functions are expanded as some linear combination of known basis functions. Various waveguide devices such as multi-mode interferometers, waveguide crossing and quasi-adiabatic tapered waveguides can be formulated and studied using present formulation.
Microstructural Characterization of Ni/YSZ Electrodes in a Solid Oxide Electrolysis Stack Tested for 9000 Hours

The effects of long-term operation in electrolysis mode on the microstructure of Ni/YSZ electrodes were investigated. The electrode structures were investigated in “as reduced” state and after 9000 h of operation in a 25 cell stack. Microstructural data were obtained by scanning electron microscopy and focused-ion-beam serial sectioning. Microstructural characteristics were extracted by 1D and 3D methods. Significant microstructural changes were observed between the two cells analyzed. A significant loss of Ni in the active electrode is observed, from ~ 29% (by volume) in the reference cell to ~ 24% as well as a coarsening of the Ni particle sizes. The long-term tested cell shows lower percolating triple phase boundary density (0.76 µm/µm 3 ) than the un-tested reference (2.0 µm/µm 3 ). This reduction is mainly due to the loss of triple phase boundary percolation through the Ni phase where a reduction from a percolation degree above 90% to ~50% is observed.
Positive Solutions of European Option Pricing with CGMY Process Models Using Double Discretization Difference Schemes

This paper deals with the numerical analysis of PIDE option pricing models with CGMY process using double discretization schemes. This approach assumes weaker hypotheses of the solution on the numerical boundary domain than other relevant papers. Positivity, stability, and consistency are studied. An explicit scheme is proposed after a suitable change of variables. Advantages of the proposed schemes are illustrated with appropriate examples.
The Objective Monitoring of Physical Activity

Epidemiologists have long recognized the significant limitations of physical activity questionnaires. Advances in the development of objective monitoring devices such as accelerometers have spurred hopes of defining more accurately the relationships between habitual physical activity and chronic disease. As yet, realization of these objectives has been curbed by the failure of accelerometers to record important sources of energy expenditure and the limitation of sample size by labor-intensive checking of output data for artifacts. But in the near future, more complex devices that link the measurement of body accelerations to other phenomena such as posture and GPS location, together with computer-assisted checking of records and processing of data may earn objective monitoring a key place in large-scale epidemiological investigations.
The "Fast and Frugal" Cognitive Architecture for Computational Social Simulations

We will define what we mean by cognitive plausibility and computational intensity. By cognitive plausibility, we mean that the observable behavior is based on models of cognition that are well received by the cognitive science and psychology community. By computational intensity we means how much of the computing resources required for the social simulation is involved in modeling the human decision-making process. We would, of course, like an approach that maximizes cognitive plausibility and minimizes computational intensity. However, neither of these dimensions is easily measured.
Vegetable Genetic Resources of Turkey

Abstract Turkey is an important center for plant genetic resources and genetic diversity. It is also one of the domestication centers where ancient agriculture started. Traditionally small-scale agriculture in Turkey has been important in bringing together some species that have hybridized causing increases in variation. The status of vegetable species germplasm, collection and characterization activities, cultivar breeding programs and utilization of the vegetable genetic resources in Turkey are detailed. Conservation and maintenance of these valuable genetic resources are necessary because these populations are important sources of diversity that could be used in future breeding programs.
Deshmukh 3 D structure prediction of lignolytic enzymes lignin peroxidase and manganese peroxidase based on homology modelling

Article info: Received: 12 August 2015 Accepted: 19 October 2015 ABSTRACT Lignolytic enzymes have great biotechnological value in biopulping, biobleaching, and bioremediation. Manganese peroxidase (EC 1:11:1:13) and lignin peroxidase (EC 1:11:1:14) are extracellular and hem-containing peroxidases that catalyze H2O2-dependent oxidation of lignin. Because of their ability to catalyse oxidation of a wide range of organic compounds and even some inorganic compounds, they got tremendous industrial importance. In this study, 3D structure of lignin and manganese peroxidase has been predicted on the basis of homology modeling using Swiss PDB workspace. The physicochemical properties like molecular weight, isoelectric point, Grand average of hydropathy, instability and aliphatic index of the target enzymes were performed using Protparam. The predicted secondary structure of MnP has 18 helices and 6 strands, while LiP has 20 helices and 4 strands. Generated 3D structure was visualized in Pymol. The generated model for MnP and LiP has Z-score Qmean of 0.01 and -0.71, respectively. The predicted models were validated through Ramachandran Plot, which indicated that 96.1 and 95.5% of the residues are in most favored regions for MnP and LiP respectively. The quality of predicted models were assessed and confirmed by VERIFY 3D, PROCHECK and ERRAT. The modeled structure of MnP and LiP were submitted to the Protein Model Database.
