Thermal Marangoni Flow Past a Permeable Stretching/Shrinking Sheet in a Hybrid Cu-Al2O3/Water Nanofluid

The present study accentuates the Marangoni convection flow and heat transfer characteristics of a hybrid Cu-Al2O3/water nanofluid past a stretching/shrinking sheet. The presence of surface tension due to an imposed temperature gradient at the wall surface induces the thermal Marangoni convection. A suitable transformation is employed to convert the boundary layer flow and energy equations into a nonlinear set of ordinary (similarity) differential equations. The bvp4c solver in MATLAB software is utilized to solve the transformed system. The change in velocity and temperature, as well as the Nusselt number with the accretion of the dimensionless Marangoni, nanoparticles volume fraction and suction parameters, are discussed and manifested in the graph forms. The presence of two solutions for both stretching and shrinking flow cases are noticeable with the imposition of wall mass suction parameter. The adoption of stability analysis proves that the first solution is the real solution. Meanwhile, the heat transfer rate significantly augments with an upsurge of the Cu volume fraction (shrinking flow case) and Marangoni parameter (stretching flow case). Both Marangoni and Cu volume fraction parameters also can decelerate the boundary layer separation process.
Effect of Defoliation and Fertilizing Time on the Growth and Flowering of Kyoho Grapes after Summer Pruning

In tropical countries, grapevines grow as evergreen and they are pruned in the time of active growing. In such summer pruning, defoliation of mature leaves and application of fertilizers are recommended for promoting bud bursting. Using the cultivar Kyoho, we conducted summer pruning and tested the effect of defoliation and fertilizing time on the growth of new shoots and flowering. On the basis of the results, we discussed the nutritional condition of the vine. 1. When all leaves were defoliated from the primary shoot at summer pruning, bud bursting was delayed and the growth of new shoots was much reduced. The development of flower clusters was restricted severely, and the berries set were only few. 2. Chemical analysis of the leaves developed on new shoots showed that defoliated vines contained less starch than un-defoliated vines. Nitrogen content was also lower in defoliated vines at the early stage of shoot growth. The nitrogen content decreased rapidly as the shoot grew in un-defoliated vines, while it increased until blooming in defoliated vines. Sugar content was also higher in defoliated vines than in those of un-defoliated. These results may be an indication that the nutrient movement to growing shoot tip or flower cluster was inactive in defoliated vines. 3. Application of fertilizers in two weeks before pruning to the un-defoliated vines resulted the longest shoot growth, though the flower development was best in the vines applicated on the same day with pruning. The highest berry setting percentage was obtained by application in two weeks after pruning.
Effect of tillage practices and fertility levels on the performance of wheat (Triticum aestivum) under mid hill condition of West Bengal

A field experiment was conducted during the winter (rabi) season of 2006 and 2007 at the Regional Research Station, Kalimpong to find out suitable conservation practices along with different dose of fertilizer for wheat (Triticum aestivum L. emend. Fiori & Paol.). Four tillage practices (surface seeding, zero tillage, minimum tillage and conventional) in main plot and 3 fertility levels (60:30:20; 80:40:30; 100:50:40 and 120:60:50 kg NPK/ha) in sub-plot were studied. Plant growth and yield attributes significantly differ with tillage practices. Grain (3 685 kg/ha) and straw yield (5 588 kg/ha) was significantly higher with minimum tillage and was at par with zero tillage practice. Minimum tillage also registered significantly higher net profit (Rs 26 521 /ha) and B: C ratio (1.92). Application of 120:60:50 kg NPK/ha registered significantly higher grain (3 758 kg/ha) and straw yield (5 645 kg/ha), fetched higher net monetary returnas (Rs 27 985 /ha) and B:C ratio (2.06), followed by zero tillage practice.
Evaluation of a New Statistical Method—TIN-Copula–for the Bias Correction of Climate Models’ Extreme Parameters

During the last decades, global and regional climate models have been widely used for the estimation of future climate conditions. Unfortunately, the models’ estimated values present important biases relative to the observed values, especially when the estimations refer to extremes. Consequently, several researchers have studied several statistical methods that are able to minimize the biases between climate models and observed values. The present study evaluates a new statistical method for bias correction: The triangular irregular network (TIN)-copula method. This method is a combination of the triangular irregular networks and the copula theory. In the present research, the new method is applied to ten Mediterranean stations and its results are compared with the bias-corrected values of three other widely used methods: The delta, the scaling, and the empirical quantile mapping methods. The analysis was made for maximum mean temperature (TMX) and minimum mean temperature (TMN) as well as for extreme precipitation (R99). According to the results, the TIN-copula method is able to correct extreme temperature and precipitation values, estimated by regional climate models, with high accuracy. Additionally, it is proven that the TIN-copula method is a useful tool for bias correction as it presents several advantages compared with the other methods, and it is recommended for future works.
DNA methylation and integrity in aged seeds and regenerated plants

Abstract Seed longevity is a complex process of key ecological and agronomic importance. DNA damage is a significant factor affecting seed ageing. Likewise, epigenetic changes can control gene expression and, therefore, seed response to ageing. The aim of the present work was to investigate the effect of ageing on nucleic acid stability and to identify reliable molecular markers that might help to monitor epigenetic changes within plant genetic resources during conservation. DNA profiles, evaluated by RAPD (random amplified polymorphic DNA), and methylation patterns, obtained by MSAP (methylation-sensitive amplification polymorphism), were compared in non-aged and aged Mentha aquatica seeds and plants produced by them. Germination decreased to 50% by storing seeds at 35°C and 12% wc for 28 days. RAPD profiles were 99% similar in these aged seeds compared to non-aged seeds. However, seedlings produced from the aged seeds showed a 13% dissimilarity compared to seedlings produced from the non-aged seeds. About 8% difference in the MSAP epigenetic profile was detected in seeds after storage and 16% difference was detected in the seedlings produced from them. This indicates that stress from high temperature and humidity during storage induced changes on the methylation state of seeds, and that changes were also detectable in the regenerated plants. Our results suggest that DNA integrity was compromised in seeds during ageing, and on seedlings produced by aged seeds. Genotype screening techniques such as RAPD and MSAP have the potential as markers of nucleic acid stability during seed ageing.
Factors Influencing Online Shopping Behaviour Intention: Theory of Planned Behaviour Approach

This study investigates consumers’ online shopping behaviour intention and identify the factors that influence their intention to shop online based on Theory of Planned Behaviour (TPB). This study used quantitative approach. Total samples of 118 respondents through convenience sampling method were conducted in three main shopping malls in Kuantan. Partial Least Square (PLS) technique of Structural Equation Modelling (SEM) was used to test the relationship between the research model construct. The results indicate that subjective norm and perceived behavioural control play important role and have positive relationship with online shopping behaviour intention. On the other hand, attitude is not a significant predictor to online shopping behaviour intention. The findings from this study will be useful and provides knowledge to sellers, manufacturers as well as web developers to improve their services.
The North American Plums ( Prunus Spp.): A Review of the Taxonomic and Phylogenetic Relationships

North America is a center of diversity for Prunus species. Tree architecture, chilling requirement, heat requirement, fruit development period, fruit size, fruit texture, disease resistance, and adaptive changes to multiple environmental condi-tions are a few examples of the traits of which tremendous genetic variability is available in the native plum species. Wild native Prunus species constitute an important potential source of genetic diversity for stone fruit breeding and selec-tion. A review of the North American plum taxonomic treatment and phylogenetic studies is described. Various studies have been done with three major groups being identified: Americana series, Chickasaw series, and Beach series.
Formação pedagógica e desenvolvimento profissional no ensino superior: perspetivas de docentes

RESUMO O texto apresenta os resultados de um estudo em que se procurou perceber que práticas de desenvolvimento profissional são reconhecidas por docentes do ensino superior, em particular para a dimensão do ensino. Visou-se ainda compreender como esses atores percecionam a formação pedagógica. Inscrevendo-se em uma abordagem mista, com recurso à técnica de entrevista e de questionário, auscultaram-se académicos afiliados a três escolas superiores de educação da região de Lisboa e Vale do Tejo. Os resultados revelam uma tendência para processos de aprendizagem de cariz artesanal, sendo valorizado o autoestudo e a socialização. No entanto, verifica-se um reconhecimento da relevância da formação pedagógica, em especial para quem não detém formação qualificante para outros níveis de ensino, surgindo como crença perfilhada a ideia de que as aprendizagens pedagógicas adquiridas para outros contextos de educação e ensino podem ser transferidas para a atuação docente no nível do ensino superior.
Seaweed Resources of India

Seaweeds yield valuable phycocolloids like agar-agar and algin which are widely Bsed in many industries. They are also utilised as food, fodder and fertiliser. Survey of natural seaweed resources and investigation of the chemical composition, methods of extraction, ecology, cultivation and other aspects related to their utilisation are therefore of utmost importance. Majority of the economic seaweeds come under three classes namely the Green algae (Chlorophyceae), the Brown algae (Phaeophyceae) and the Red algae (Rhodophyceae) and they are generally restricted to the relatively narrow littoral and sublittorial belts of the marine environment.
Determining the Load Inertia Contribution from Different Power Consumer Groups

Power system inertia is a vital part of power system stability. The inertia response within the first seconds after a power imbalance reduces the velocity of which the grid frequency changes. At present, large shares of power system inertia are provided by synchronously rotating masses of conventional power plants. A minor part of power system inertia is supplied by power consumers. The energy system transformation results in an overall decreasing amount of power system inertia. Hence, inertia has to be provided synthetically in future power systems. In depth knowledge about the amount of inertia provided by power consumers is very important for a future application of units supplying synthetic inertia. It strongly promotes the technical efficiency and cost effective application. A blackout in the city of Flensburg allows for a detailed research on the inertia contribution from power consumers. Therefore, power consumer categories are introduced and the inertia contribution is calculated for each category. Overall, the inertia constant for different power consumers is in the range of 0.09 to 4.24 s if inertia constant calculations are based on the power demand. If inertia constant calculations are based on the apparent generator power, the load inertia constant is in the range of 0.01 to 0.19 s.
Etiology of Poverty: A Critical Evaluation of Two Major Theories

The purpose of this article is to appraise two competing frameworks related to poverty attribution: individualistic theories and structural theories. Using the Theory Evaluation Scale (TES)—an empirically validated nine-criterion measure—this paper scrutinizes the aforementioned theories for coherence, conceptual clarity, philosophical assumptions, connection with previous research, testability, empiricism, limitations, client context, and human agency. Results revealed that, at the scale level, both perspectives are of excellent quality. However, at the item-level, the structural perspective was found to be significant-ly stronger than the individual perspective. Therefore, the structural perspective is an epistemologically sounder framework for informing antipoverty interventions.
Anal incontinence in patients with fistula-in-ano: a comparative study between LIFT (ligation of inter-sphincteric fistulous tract) and fistulectomy

Background: General surgeons perform surgeries for Fistula in ano day in and day out as elective procedures. Fistula in ano is more common nowadays because of improper hygiene. 3 major basic aims of Fistula in ano surgeries are control of sepsis closure of fistula and maintenance of continence. Post operatively some patients developed anal incontinence due to sphincter injury which affects patients’ day to day activity. The present study compared the utility and effectiveness of two standard procedures LIFT (Ligation of Intersphincteric Fistula Tract) and Fistulectomy in terms of anal incontinence.Methods: This study included 100 patients with fistula in ano during the 6 months period from January 2017 to June 2017. Randomized controlled trial was done to divide the patients into two groups. Group A underwent fistulectomy and Group B underwent LIFT (Ligaton of intersphincteric fistulous tract). Post-operative anal incontinence between the two groups were observed for 6 months.Results: In our study it was observed that four patients of group A (fistulectomy) had anal incontinence whereas no patients in group B (LIFT) developed anal incontinence.Conclusions: LIFT (Ligation of intersphincteric fistulous tract) is a better procedure when compared to fistulectomy in preserving sphincter function and preventing anal incontinence offering better quality of life.
Fostering empowerment through occupation: An overview of an urban school-based parenting program

ABSTRACT Occupational scientists have long examined the challenges of discrimination within societies, and this paper utilizes qualitative research to examine a) occupational justice and how it relates to the social inequality of pregnant and parenting students; b) the connection of United States Title IX federal law and occupational justice; c) how a pregnant and parenting school-based program in a Midwest Urban School District utilized Title IX federal law and concepts of occupational justice to address academic and social inequality; and d) how the Parent Infant Interaction Program (PIIP) administrators implemented socially and culturally responsive occupation-based interventions to empower pregnant and parenting students. As a qualitative case study, this inquiry used content analysis of documents and open coding of semi-structured interviews with administrative stakeholders, to draw upon historical, demographic, and narrative data. This article will exemplify how an educational program and its administrators, as identified through the Participatory Occupational Justice Framework, Culturally Relevant, and Culturally Responsive Framework, aimed to forge parenting students’ occupational agency and create a framework to allow them to achieve their academic and personal goals.
Biofilm Growth in Two Streams Draining Mountainous Permafrost Catchments in NE Greenland

The objective of this study was to evaluate how stream water nutrient concentrations influence biofilm accrual in streams draining mountainous permafrost headwaters. We selected six stream locations in the Zackenberg area (NE Greenland, 74°N) subjected to a gradient in the areal contribution of different geomorphological units in the watersheds and channel stability. We used nutrient diffusing substrates to evaluate biofilm growth (autotrophic and total biomass). We found elevated stream nitrate concentrations in samples from upstream reaches draining larger areas of solifluction sheets and bare rock and with higher channel instability. Nitrate had the highest standardized effect on autotrophic biofilm growth on control disks. However, stream biofilm growth was not nutrient limited as shown by the absence of an increase in biofilm biomass as a response to the experimental nutrient additions. The response to nutrient additions via diffusing substrates depended on the altitude gradient. Overall, our results showed stream nitrogen availability to be one of the main drivers of algal biofilm accrual in high‐Arctic streams, suggesting that the predicted changes in nutrient exports induced by climate change will have strong impacts on the biogeochemistry and ecological functioning of high‐Arctic streams.
Molecular Mechanisms of Learning, Memory and Aging

textabstractAging, or rather, how to avoid it, has intrigued mankind from the earliest times. It has been a quest comparable to the alchemists’ search for a way to turn lead into gold. Just as the alchemists spawned chemistry the quest for the fountain of youth has led to a large body of research into aging. Among the many theories on the nature of aging the oxidative stress hypothesis is the most plausible one. This theory states that the lifelong accumulation of oxidative damage to biological macromolecules such as proteins, DNA and lipids is the mechanism underlying aging. Considering that DNA contains all the information needed to build and maintain a cell, it is surmised that (oxidative) damage to DNA is the predominant contributor to aging. In support of this idea are the accelerated segmental aging phenotypes of humans and mice with defects in DNA repair mechanisms.
A Novel BioTarget in Treatment of Heart Failure: Changes in Serum Galectin-3 Levels after Spironolactone Therapy

Objective: It has been aimed to investigate the Galectin-3 (GAL-3) levels and clinical responses after addition of spironolactone as a mineralocorticoid receptor antagonist (MRA) to the current treatment in patients with heart failure with low ejection fraction who received no aldosterone antagonist therapy previously. Patients and methods: The study included 112 patients with Heart Failure (HF) who showed left ventricular Ejection Fraction (EF) of 35% or below, New York Heart Association (NYHA) Class II-IV symptoms and did not receive MRAs in their current treatment. Serum Gal-3 levels, serum BNP level, 6-minute walk test and class level of NYHA were examined before and 6 months after treatment of spironolactone in all patients. Results: Mortality developed in 10 of 112 patients. Baseline and 6th month follow-up data obtained from 102 of 112 patients. Mean LVEF (%), BNP levels, Gal-3 levels, NYHA class of functional capacity and mean 6-minute walking test distance of the patients before treatment of spironolactone were 31.3 ± 3.2%, 451,4 ± 50.3 pg/ml, 39 ± 21 ng/ml, 2,8 ± 0.59 and 305 ± 61 m respectively whereas, the same variables were found 32.1 ± 2,8% (p=0.21), 443.6 ± 49 pg/ml (p=0.23), 33 ± 22 ng/ml (p=<0.001), 2,5 ± 0.47 (p=0.037) and 386 ± 87 m (p=<0.001) respectively at 6th follow-up after treatment of spironolactone. Conclusion: Spironolactone use is associated with regression of Gal-3 along with clinical improvement in HF symptoms. This may suggest that Gal-3 apart from being a biomarker of HF may also be a bio-target in HF management.
Effects of score-line on internal and external load in soccer small-sided games

ABSTRACT The aim of this study was to analyse the effect of the score-line on the internal and external load in soccer small-sided games (SSGs). Thirty male semi-professional soccer players participated in an acute crossover design study. Players performed 4 series of 4 vs 4 with a game duration of 4 min. The data corresponding to players’ external load were collected using a portable Global Positioning System device and players’ internal load using rating of perceived exertion. The results showed that players covered significantly higher total distance (effect size [ES]: 0.63–55), medium-intensity distance (ES: 0.81–82), and high-intensity running distance (ES: 0.86–0.53) when the final result of SSGs was a draw in comparison when losing or winning. Players’ power score was significantly higher when the final result of SSGs was a draw compared to when was a loss (ES: 0.77). On the contrary, players covered significantly shorter walking distance when drawing compared to losing (ES: 0.55) and winning (ES: 0.63). Present results indicate players’ external load during SSGs is related to the final score-line. In order to maximise players’ external load during SSGs, teams should be as balance as possible to increase the probability of a draw score-line.
Job insecurity and work–family conflict

Drawing on conservation of resources theory, this study aims to investigate the processes underlying the linkages between job insecurity (JI) and work–family conflict (WFC) from a stress perspective, focusing on the mediating role of subordinates' work withdrawal (WW) and emotional exhaustion (EE). Specifically, the authors tested two distinct mediating mechanisms, namely, WW and EE that have received less attention in testing the JI and WFC linkage. The authors also tested the variable of perceived organizational justice (POJ) to moderate these relationships. ,Survey data collected at Time 1 and Time 2 included 206 professionals from different occupational sectors. The authors study independent variable (i.e. JI), moderator (POJ) and mediator (WW) were measured at Time-1, whereas the other mediator (EE) and outcome (WFC) were tapped by the same respondent at Time-2 with a time interval of one month between them. ,The findings suggest that subordinates’ EE and WW mediate the relationship between JI and WFC. Further, the authors found that EE is a relatively more effective mechanism than WW in explaining how and why JI translates into WFC. The results of the moderated mediation analysis revealed that the indirect effect of JI on WFC is strengthened when POJ is low. ,JI has adverse consequences on the employees’ well-being and a cost to the organization in terms of WW. HR and top management should anticipate the negative influence of WW and EE and should focus on nurturing positive work–family climates to help reduce WFCs. Managers should give employees opportunities for participation and foster a climate of fairness in the organization to mitigate the harmful consequences of JI. ,This study contributes to the employees’ burnout, counter work behavior and the WFC literature. By introducing EE and WW as underlying mechanisms and identifying POJ as a work contextual variable to explain the JI – WFC relationship, the authors extend the nomological network of JI. The authors respond to the calls by prior researchers as little research has examined how perceived fairness (unfairness) can induce WFC.
