Variability in leaf and crown morphology correlated with light availability in five natural populations of Quercus castaneifolia C.A. Mey

Babaei F. , Jalali S.G. , Sohrabi H. , Shirvany A. (2017): Variability in leaf and crown morphology correlated with light availability in five natural populations of Quercus castaneifolia C.A. Mey. J. For. Sci., 63: 275–281. In this study, we investigate seedlings of Quercus castaneifolia C.A. Mey, from five different provenances for the research on leaf and crown morphological variations in relation to a light gradient under controlled conditions in a greenhouse. The results show that significant variations occurred in many parameters due to the effects of light availability. The seedling responses to low light include the proportional allocation of more biomass to leaves, leading to higher leaf mass, leaf area, crown area, specific leaf area and leaf area ratio, in contrast, the seedlings grown in high irradiance faced a high temperature resulting in higher transpiration. At this period, seedlings alter their leaf and crown size to prevent overheating. In this experiment, in spite of the same treatments in controlled conditions in a greenhouse, the seedlings from different provenances indicate different responses to light levels. It seems that the seedlings try to maximize their surface area for the intake of light as the most limiting resource in wet provenances. Such responses under the same treatment are adaptive strategies which allow oak seedlings to have the best function under stressed conditions. For Q. castaneifolia as a species with broad fundamental niches in Hyrcanian forests, these variations may be achieved by a combination of genotypic differentiation and phenotypic plasticity.
Prediction of Elite Male Trampolines' Performance Based on the Selected Psychological Capabilities

Main purpose of this study was prediction of elite male trampolines' performance based on the selected physical and psychological capabilities in different age categories. To this aim, 45 male athletes, athletic experience and competitive experience, who participated in the national trampoline team's preparation camps for participation at the 2014 Asian Games in four age categories included Children (ages 11 and 12 yrs), Juniors (ages 13 and 14 yrs), Adolescents (ages 15 to 17 yrs), and Seniors (ages 18 yrs <), were selected using targeted sampling as subjects. Variables of study included 16 variables related to mental skills which were measured using standard procedures and instruments. Data were analyzed using Pearson correlation coefficient and multiple regression models at the 0.05 significance level. Results of study showed that, among all relationships between variables, self-confidence ( r =0.359), concentration ( r =0.316), concentration recovery ( r =0.394), average of psycho-cognitive skills ( r =0.304), and total average of mental skills ( r =0.307) with performance are statistically significant. Results of regression analysis showed that self-confidence ( β =0.522) and concentration recovery ( β = 0.377) are significant determinants of performance which explain totally 26.7 percent of the elite male trampolines' competitive performance. Findings of this study suggest that, in the high competitive level of trampoline, psychological factors (i.e., self-confidence and concentration recovery) have more predictive role which must be considered in preparation programs of elite male trampolines.
NGTS-2b: an inflated hot-Jupiter transiting a bright F-dwarf

We report the discovery of NGTS-2b, an inflated hot-Jupiter transiting a bright F5V star (2MASS J14202949-3112074; $T_{\rm eff}$=$6478^{+94}_{-89}$ K), discovered as part of the Next Generation Transit Survey (NGTS). The planet is in a P=4.51 day orbit with mass $0.74^{+0.13}_{-0.12}$ M$_{J}$, radius $1.595^{+0.047}_{-0.045}$ R$_{J}$ and density $0.226^{+0.040}_{-0.038}$ g cm$^{-3}$; therefore one of the lowest density exoplanets currently known. With a relatively deep 1.0% transit around a bright V=10.96 host star, NGTS-2b is a prime target for probing giant planet composition via atmospheric transmission spectroscopy. The rapid rotation ($vsin$i=$15.2\pm0.8$ km s$^{-1}$) also makes this system an excellent candidate for Rossiter-McLaughlin follow-up observations, to measure the sky-projected stellar obliquity. NGTS-2b was confirmed without the need for follow-up photometry, due to the high precision of the NGTS photometry.
Molecular Characterization and Analysis of the Greek Citrus Germplasm

Molecular markers were used to evaluate genetic similarity among 36 citrus accessionsc ( C. sinensis, C. reticulata, C. limon and cultivars) of the Greek national clonal germplasm repository located in Poros. In total, nine RAPD and five ISSR primers produced 262 loci, of which 236 were polymorphic. Both techniques were proven to be equally analytical with an average discrimination power above 0.9. The RAPD and ISSR markers were highly correlated and clustering among them had high correspondence. Citrus accessions formed separate clusters according to their species, even though sweet orange and mandarin cultivars revealed high affinity, while lemons were more divergent. C. sinensis genotypes had the highest intragenetic affinity suggesting that cultivated oranges have a narrow genetic base. On the contrary, the C. reticulata group was the most variable. In general, Greek varieties exhibited a distinctive genetic background that could be discriminated from foreign established cultivars using the mentioned molecular techniques. This information could facilitate their use in future Citrus spp. breeding programs.
Off-pump or on-pump coronary-artery bypass grafting at 30 days.

BACKGROUND The relative benefits and risks of performing coronary-artery bypass grafting (CABG) with a beating-heart technique (off-pump CABG), as compared with cardiopulmonary bypass (on-pump CABG), are not clearly established. METHODS At 79 centers in 19 countries, we randomly assigned 4752 patients in whom CABG was planned to undergo the procedure off-pump or on-pump. The first coprimary outcome was a composite of death, nonfatal stroke, nonfatal myocardial infarction, or new renal failure requiring dialysis at 30 days after randomization. RESULTS There was no significant difference in the rate of the primary composite outcome between off-pump and on-pump CABG (9.8% vs. 10.3%; hazard ratio for the off-pump group, 0.95; 95% confidence interval [CI], 0.79 to 1.14; P=0.59) or in any of its individual components. The use of off-pump CABG, as compared with on-pump CABG, significantly reduced the rates of blood-product transfusion (50.7% vs. 63.3%; relative risk, 0.80; 95% CI, 0.75 to 0.85; P<0.001), reoperation for perioperative bleeding (1.4% vs. 2.4%; relative risk, 0.61; 95% CI, 0.40 to 0.93; P=0.02), acute kidney injury (28.0% vs. 32.1%; relative risk, 0.87; 95% CI, 0.80 to 0.96; P=0.01), and respiratory complications (5.9% vs. 7.5%; relative risk, 0.79; 95% CI, 0.63 to 0.98; P=0.03) but increased the rate of early repeat revascularizations (0.7% vs. 0.2%; hazard ratio, 4.01; 95% CI, 1.34 to 12.0; P=0.01). CONCLUSIONS There was no significant difference between off-pump and on-pump CABG with respect to the 30-day rate of death, myocardial infarction, stroke, or renal failure requiring dialysis. The use of off-pump CABG resulted in reduced rates of transfusion, reoperation for perioperative bleeding, respiratory complications, and acute kidney injury but also resulted in an increased risk of early revascularization.

Effects of tool rotating rate and pass number on pore structure of A6061 porous aluminum fabricated by using friction stir processing

As a new fabrication method of porous aluminum with the advantages of high productivity and low manufacturing cost, the authors proposed a fabrication method called the ‘‘FSP route precursor method’’. FSP (friction stir processing) is a solid-state process involving the generation of friction heat and intense plastic flow simply by inserting a rotating tool and allowing it to traverse through the aluminum alloy matrix. In this method, the precursor is manufactured by mixing a blowing agent powder and a stabilization agent powder into the aluminum alloy matrix using the intense stirring action of FSP. Then, porous aluminum can be obtained by foaming the precursor under suitable conditions. In this study, aluminum alloy 6061 (A6061) plates are used as a starting material and porous aluminum is fabricated by applying the procedure of multipass FSP. The effects of the tool rotating rate and the number of passes on the porosity and pore structure of A6061 porous aluminum are investigated. To obtain porous aluminum with high porosity and high quality (i.e., a uniform pore size distribution and highly spherical pores), the tool rotating rate should be approximately from 1000 to 2200 rpm when the rotating tool traverses the matrix four times and the foaming conditions (holding temperature and holding time when the blowing agent is foamed) are optimized. The porous aluminum obtained has a porosity of 70%, and the average equivalent diameter of pores is approximately from 1.5 to 2 mm. [doi:10.2320/matertrans.MBW200916]
An In-depth Study on the Performance Impact of CUDA, OpenCL, and PTX Code

In recent years, the rise of GPGPU as a viable solution for high performance computing has been accompanied by fresh challenges for developers. Chief among these challenges is efficiently harnessing the formidable power of the GPU and finding performance bottlenecks. Many factors play a role in a GPU application's performance. This creates the need for studies performance comparisons, and ways to analyze programs from a fundamental level. With that in mind, our goal is to present an in-depth performance comparison of the CUDA and OpenCL platforms, and study how PTX code can affect performance. In order to achieve this goal, we explore the subject from three different angles: kernel execution times, data transfers that occur between the host and device, and the PTX code that is generated by each platform's compiler. We carry out our experiments using ten real-world GPU kernels from the digital image processing domain, a selection of variable input data sizes, and a pair of GPUs based on the Nvidia Fermi and Kepler architectures. We show how PTX statistics and analysis can be used to provide further insight on performance discrepancies and bottlenecks. Our results indicate that, in an unbiased comparison such as this one, the OpenCL and CUDA platforms are essentially similar in terms of performance.

A convergent mass conservative numerical scheme based on mixed finite elements for two-phase flow in porous media

In this work we present a mass conservative numerical scheme for two-phase flow in porous media. The model for flow consists on two fully coupled, non-linear equations: a degenerate parabolic equation and an elliptic equation. The proposed numerical scheme is based on backward Euler for the temporal discretization and mixed finite element method (MFEM) for the discretization in space. Continuous, semi-discrete (continuous in space) and fully discrete variational formulations are set up and the existence and uniqueness of solutions is discussed. Error estimates are presented to prove the convergence of the scheme. The non-linear systems within each time step are solved by a robust linearization method. This iterative method does not involve any regularization step. The convergence of the linearization scheme is rigorously proved under the assumption of a Lipschitz continuous saturation. The case of a H\"older continuous saturation is also discussed, a rigorous convergence proof being given for Richards' equation. Numerical results are presented to sustain the theoretical findings.
Silence is not Golden: The Effects of Prohibitive Voice on Customer Citizenship Behaviors

This work analyzes the effects that service employee prohibitive voice behavior has on customer perceptions of the procedural justice received, and the consequent customer citizenship behaviors (CCB). Prohibitive voice expresses the service workersi¯ concern about existing or upcoming practices, events, or acts that may harm their service outcome. While this voice has been recognized as constructive and helpful to organizations, its roles regarding customer perceptions and CCB remain unexplored. Beginning with a brief review of the conceptual background of prohibitive voice, procedural justice and CCB, this paper proposes a model to test these relationships empirically. This study contributes to service research by applying the concept of i°prohibitive voicei± to service encounters. Implications for managing service encounters are also discussed herein.
Transversal analysis of junk food diet for a group of medical students and its association with metabolic syndrome

Abstract Objective: to evaluate the nutritional behavior of medical students regarding junk food intake in relation with the metabolic syndrome (MS). Material and Method: 235 medical students completed a food frequency questionnaire; MS risk factors were recorded. Junk food was grouped in 5 categories, according to the predominant nutrient in its composition. Statistical data were processed by SPSS program. Results: 97% of subjects did not fully comply with the WHO recommendations of healthy nutrition. No statistically significant correlations were found between the nutritional intake of nutrients or junk food categories and waist circumference or HDLc, except the glycemic index in women (r=-0.230, p=0.003). A correlation between the intakes of different categories of junk food was found. Conclusions: Most subjects consume in excess nutrients considered risk factors and very few have an optimum intake of nutritional protection factors against MS. The “western diet” pattern prevalent in this population is an argument for educational interventions.
Role of Micro-Financing in Creation of Self-Employment in Pakistan: A Case Study of District Bahawalpur

Employment problem is one of the key issues in developing countries especially in Pakistan. Self-employment (own business) is integral part of the society, majority of the people of our country is belong to business sector. Micro finance plays role in improving self-employment through business or productive activities. In this study an attempt is made to explore the determinants of self-employment in which micro finance is key determinant. This study used bivariate regression analysis based on primary data of Bahawalpur City and to check the relationship of different socio economic determinants on self-employment. Self-employment is measured by binary number as 01 coding of dummy dependent. As taking loan or not taking loan. Similarly all explanatory variables measured by binary coding shape of 01.The results show that self-employment at remarkably influenced by age, education, sex, family wealth, marital status, technical skill, micro finance and loan purpose. More over at the end it is concluded that microfinance is major independent variable in this research and it has positively and highly significant impact on self-employment,i.e. 200% or 2 times may can increase self-employment if provides loan at easy grounds. Keywords: microfinance, self-employment, bivariate logistic regression,
Attribute Order in Chinese and English

The authors found that the order of attribute presentation had a stronger effect on judgment in English than Chinese. In experiment 1, using 102 female and 63 male bilingual Singaporeans, memory-based judgments showed a stronger primacy effect in English than in Chinese that was mediated by recall from long-term memory. In contrast, participants’ online (immediate) judgments showed a primacy effect in both languages that was unmediated by recall from short-term memory. In experiment 2, using 67 female and 53 male bilingual Singaporeans, online judgments were more influenced by the attribute order of a previously seen competitive ad in English than Chinese. A cross-cultural field study in mainland China and the U.K. provided external validity for the experimental results.
From the sparse to the statistical limit of intramolecular vibrational redistribution in vibrational predissociation: ArCl2 as an example

The dynamics of intramolecular vibrational relaxation (IVR) for ArCl2 are examined for a wide range of vibrational and rotational excitation. In order to describe the IVR more efficiently, and characterize it more quantitatively, we propose a refinement of the traditional Bixon-Jortner description in which the active states are prediagonalized to simplify the coupling scheme that must be considered. This allows for an explicit determination of the average density of states and average coupling strength for each initial excitation. We find that the IVR dynamics proceed from the sparse regime for v=11, for which the first open dissociation channel corresponds to the loss of two Cl2 quanta, to the intermediate-dense regime for v=25 which dissociates by the loss of 4 quanta. We find that over this range the increase in the density of states is less important than the increase in the coupling strength. For v = 18 we examine the effect of rotation in considerable detail. Initial states that couple via a manifol.
Estrus response and pregnancy rate of Rusa timorensis following estrus synchronization with prostaglandin analogue.

The purpose of this study was to evaluate the efficacy of cloprostenol in inducing estrus in cycling Rusa timorensis hinds by assessing circulating progesterone (P4) concentration, occurence of estrus and pregnancy rate. Estrus was synchronized in eight cycling hinds with 500 μg cloprostenol given intramuscularly at 10 days apart. Eight other R. timorensis hinds were notsynchronized and served as control. Blood samples, collected every three to four days for 29 days from 24 hours prior to the first cloprostenol injection, were analyzed for plasma progesterone concentration. Estrus was recorded based on observation of estrus signs during the period of blood sampling and all hinds were subjected to transrectal ultrasonography to assess pregnancy status. On the basis of changes in plasma progesterone concentration, cloprostenol induced estrus in only 63% of the treated hinds. The other three treated hinds showed progesterone values (0.8 ng/mL) which appeared to be too low to indicate presence of corpus luteum for the drug to act on. Spontaneous estrus occurred in 50% of the untreated hinds. Five of the 8 treated hinds and four control hinds displayed standing estrus. Pregnancy rate to cloprostenol induced estrus following natural mating was good with 50% of the treated hinds conceived. In the present study, estrus synchronization had been successfully achieved using prostaglandin analogue.
Still Talking, But Is Anyone Listening?

Constituency electioneering has become established as an important element of postmodern political campaigning, allowing parties and candidates to focus effort on targeted seats. A substantial literature has developed, showing the efficacy of such targeting: other things being equal, the harder parties campaign locally, the more votes they win relative to their rivals. However, on the whole, such studies have taken a relatively static view of local campaigning, concentrating on particular elections. Yet there are a priori grounds to expect the efficacy of local campaigns to vary from party to party and from election to election. In this article, we therefore analyse dynamic trends in constituency campaigning using a pooled data set of British constituency electioneering between 1997 and 2005. The results illustrate important and substantial variations over time and across parties in the impact of local election campaigning.
Prospects for very high energy observations of Starburst/Seyfert galaxies

A handful of non-blazar galaxies, including both Seyfert and starburst galaxies, have been observed to emit gamma-rays by the Fermi Gamma-ray Space Telescope. For one of these objects, NGC 1068, a starburst galaxy which is also the brightest and closest Seyfert 2, a galactic outflow driven by the active nucleus is a likely source of both the radio and gamma-ray spectra, and we compare this case to other possible explanations including starburst activity and blazar-like jet emission. Other galaxies with both starburst and Seyfert characteristics, including NGC 4945, NGC 253, Circinus, and NGC 3256, show varying degrees of evidence of starburst, AGN mini-jet and AGN-driven outflow. Given the existence of various possible emission mechanisms operating at high energies, we discuss prospects for observations of starburst/Seyfert galaxies with Fermi, HESS and the Cerenkov Telescope Array (CTA), as well as future neutrino telescopes such as KM3NeT.
Ageist Attitudes and Their Association with Burnout and Job Satisfaction Among Nursing Staff: A Descriptive Study

YAŞLI BAKIM PERSONELLERİNİN YAŞLI AYRIMCILIĞI İLE İLGİLİ TUTUMLARI İLE TÜKENME VE İŞ MEMNUNİYETİ ARASINDAKİ İLİŞKİSİNİN İNCELENMESİ: TANIMLAYICI BİR ÇALIŞMA Introduction: The various factors affecting burnout and job satisfaction among nursing staff have yet to be clearly identified. Accordingly, this study examines one of those potential factors, ageist attitudes, and its relation with burnout and job satisfaction among nursing home employees. Materials and Method: This was a cross sectional multi-center study which was conducted in 2017. Ageism was evaluated using the Ageism Attitude Scale (subscales: restricting life of the elderly, positive ageism, and negative ageism); burnout level was evaluated using the Maslach Burnout Inventory (subscales: emotional exhaustion, depersonalization, and personal satisfaction); and job satisfaction was evaluated using the Short-Form Minnesota Satisfaction Questionnaire. Correlation between variables were analyzed Spearman Correlation test. Results: Positive ageism was positively correlated with personal accomplishment and job satisfaction scores (p<.05) and negatively correlated with depersonalization (p<.05). ShortForm Minnesota Satisfaction Questionnaire scores were negatively correlated with emotional exhaustion and depersonalization and positively correlated with personal accomplishment variables (p<.05). Conclusion: Ageism negatively impacts not only elderly individuals but also the nursing staff who care for them. Educational programs to prevent ageism should be evaluated for efficiency and implemented if proven to be beneficial.
