Combined-hole film cooling with the application of double flow control devices

In the modern gas turbine, film cooling system was applied to the turbine blades to provide thermal protection from extreme turbine inlet temperatures. Recent literature discovers that adding the double flow control device (DFCD) and combining two cylindrical holes (combinedhole) are the ways to further enhance the film cooling performances. In the present simulation work, the influence of DFCD on the combined-hole film cooling was investigated at different blowing ratios. The comparison between two different computational domains of combined-hole film cooling with and without DFCD was further discussed in the present work. The results show that increase the blowing ratio, M rise the overall performance of combined-hole film cooling with and without DFCD. Based on the different computational domain, combined-hole with DFCD has better lateral spread at M = 0.5 and M = 0.75 in comparison with the combined-hole without DFCD. However, due to large counter clockwise vortex produced by the combined-hole with DFCD, unsymmetrical film cooling coverage was formed along the streamwise direction at M = 1.0 and M =1.5. As the conclusion, combined-hole film cooling with DFCD has better performance at M = 0.5 and M = 0.75 while combined-hole film cooling without DFCD has better performance at high blowing ratio of M = 1.0 and M = 1.5.
LGMS-FOA: An Improved Fruit Fly Optimization Algorithm for Solving Optimization Problems

Recently, a new fruit fly optimization algorithm (FOA) is proposed to solve optimization problems. In this paper, we empirically study the performance of FOA. Six different nonlinear functions are selected as testing functions. The experimental results illustrate that FOA cannot solve complex optimization problems effectively. In order to enhance the performance of FOA, an improved FOA (named LGMS-FOA) is proposed. Simulation results and comparisons of LGMS-FOA with FOA and other metaheuristics show that LGMS-FOA can greatly enhance the searching efficiency and greatly improve the searching quality.
State Ownership, Institutional Ownership and Relationship with Firm Performance: Evidence from Chinese Public Listed Firms

State ownership and institutional ownership both play important roles in Chinese public listed firms. This study tests empirically the impacts of state ownership and institutional ownership on firm performance in China, using a large sample for the period of 2008 to 2014. It finds that there is a U-shape relationship between state ownership and firm performance. The results that reveal in most situations, state ownership has negative influences on firm performance because state owners pursue with political goals instead of profit maximization. This study also finds that institutional ownership is positively related to firm performance; the institutional investors have more incentives and financial competencies to monitor management therefore enhancing good firm performance.
A model for stress analysis of elastomer samples’ crystallisation in a solid mechanics problem accounting for superimposed finite strains

A mathematical model, method and an algorithm for numerical analysis of stress and strain in elastomeric samples under crystallisation are presented. The stress and strain analysis is performed by means of a CAE Fidesys program module based on the proposed algorithm. The results show that accounting for crystallisation effects is essential for the correct estimation of the stress and strain state of elastomeric samples. 1218 Vladimir Anatolievich Levin et al.

Development of CO2 snow cleaning for in situ cleaning of µCMM stylus tips

Contamination adhered to the surface of a µCMM stylus tip compromises the measurement accuracy of the µCMM system, potentially causing dimensional errors that are over ten times larger than the uncertainty of a modern µCMM. In prior work by the authors, the use of a high pressure CO2 gas stream was demonstrated to achieve significant cleaning rate for a range of contaminant without damage to the stylus tip surface. This paper explores the practical challenges of achieving effective stylus tip cleaning in situ on µCMM systems. Two types of snow cleaning approaches were evaluated for their coverage of cleaning, thermal impact and gas flow forces. This work then presents a novel multi-nozzle prototype system using pulsed snow streams to achieve cleaning coverage over the entire stylus tip, and balances forces from the snow streams reducing drag force imparted by the gas stream to levels comparable to the probing force of µCMMs, as well as allowing automated cleaning procedure integrated into a µCMM system.
Measures of Aggression in Young Korean Children: A Review of 10 Years of Empirical Research

The present study reviewed types of Korean versions of aggression measures for preschool children, which have been used in recent studies of Korea, and then examined the evidence of the reliability and validity of the measures. We also examined gender differences using meta-analysis. Forty six articles, which were published from 2005 through 2014, were selected from scientific databases. Results showed that the PSBS was most frequently used, followed by the PBQ, the CBCL and the SCBE in Korea. Cronbach's alpha ranged between . 70 and . 97 across measures except one, indicating acceptable levels of internal consistency. The result of the meta-analysis indicated that boys displayed significantly higher aggression. This was consistent in findings of previous studies, stating that boys showed more overt aggression than did girls. However, gender difference in relational aggression was not significant. The results of this study provide information how reliable and valid measures are to researchers aiming to conduct a comparative cultural study involving Korea. In the future, relational aggression will need to be assessed from multiple informants such as peers, teachers, parents, and observers.
The Prediction of the Wall Bounded Turbulent Flows Using the Code PASSABLE

Turbulent flows for flat plate and circular pipes were solved using the two equation k-e model and the algebraic stress model (ASM). The computations were carried out using the parabolic solver PASSABLE code which uses a finite-difference and finite-volume approach with a forward maching technique. The results obtained with the code were compared with the results described in the literature and a good agreement was found.
In-store arousal and consumers’ inferences of manipulative intent in the store environment

Purpose – The purpose of this article is to show how consumers’ inferences of manipulative intent mediate the effects of in-store arousal on pleasure and approach behavior. Design/methodology/approach – A qualitative study identifies arousal as a dimension of the store environment that may lead to inferences of manipulative intent. An experiment manipulating arousal tests the mediating effect of inferences of manipulative intent on the relationship of arousal with pleasure and approach behavior. Findings – A qualitative study and the results of an experiment suggest that arousing store environments lead to negative outcomes when consumers infer that such environments are manipulative. The experimental study results show that high in-store arousal increases inferences of manipulative intent, which in turn negatively affect pleasure and approach behaviors. The results also indicate that the effects of in-store arousal on inferences of manipulative intent vary with age. Practical implications – The study res.
Phosphorylcholine-coated extracoporeal circulation systems affect coagulation factors during cardiopulmonary bypass insufficiently: a preliminary report Fosforilkolin kapli ekstrakorporeal dolaşim sistemleri koagülasyon faktörlerini yetersiz düzeyde etkiler: Ön rapor

Background:­ This study aims to investigate the efficacy of the phosphorylcholine (PC)-coated extracorporeal circulation (ECC) circuits compared to the non-coated ECC circuits in patients undergoing isolated coronary artery bypass grafting (CABG). Methods: Twenty-eight patients (24 males, 4 females; mean age 62±12 years; range 41 to 84 years) who underwent elective CABG due to ischemic heart disease were enrolled in this single-blind prospective study with the odd-even number of randomization method. Phosphorylcholine-coated ECC systems were used in group 1 and non-coated ECC systems were used in group 2. The percentage of the coagulation factor activations [factor (F)-II, F-V, F-VII, F-VIII, F-X, F-XII, and von Willebrand factor], D-dimmer, and anti-thrombin III levels were measured preoperatively, intraoperatively and postoperatively. Results:­ The percentage of activation of F-II and F-X in group 1 were significantly higher than group 2 before the cross-clamp removal (T1) (p 0.05). Conclusion:­ Although the percentage of activation of the factors is higher in non-coated ECC systems compared to PC-coated ECC systems, it does not indicate significant clinical differences. In addition, both PC-coated or non-coated ECC systems exert similar biological effects during cardiopulmonary bypass.
Ball recovery patterns as a performance indicator in elite soccer

In soccer, it seems relevant to understand the relationship between the ball recovering and the subsequent success or failure of attacking play. However, few studies have considered the links between the type of ball recovery in different pitch zones, the competition stages and the overall teams success. The present study aims to analyze the attacks (n = 1619) carried out by the semi-finalist teams in the 2010 FIFA World Cup in order to explore ball recovery patterns as a performance indicator. SoccerEye observational instrument, SoccerEye recording software, Sequential Data Interchange Standard-Generalized Sequential Querier (SDIS-GSEQ) and SPSS analytic software—one-way analysis of variance, two-way analysis of variance and regressions—were applied. Direct ball recovery, in specific by interception and defensive behavior followed by a pass, was the mostly frequent behavior, with the later inducing attacking play efficacy (p<0.017). Differences were detected between the group and play-off stages with regard to the types of direct ball recoveries. The ball was most often regained in defensive and mid-defensive central zones, evidencing differences to all other pitch zones (p≤0.001). Throw-ins were the only type of ball recovery that differentiated the semi-finalists, namely Germany and Spain (p<0.009). It was found that recovering directly the ball possession in mid-defensive central zones increases attacking efficacy. Consequently, coaches should consider this tactical determinant in order to organize the training process. Specifically, it is fundamental to improve the collective defensive organization protecting central strip zones and simultaneously performing high-pitched pressure to constrain the ball carrier.
Effect of Using Enzyme Complex on Productivity and Hatchability of Broiler Breeders Fed a Corn-Soybean Meal Diet

A total number of 5520 female and 480 male breeders (Arbor Acres plus) at 42wks of age were used in a 10-week-trial to investigate the effect of an enzyme complex on the quality and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. There were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzyme group that received the same diet plus an enzyme complex including xylanase, amylase, protease, phytase, s-glucanase, hemicellulase, and pectinase. Results showed that egg production rate and egg mass were numerically increased as a result of enzyme supplementation and differences between the treatment groups were significant at week 46 (P<0.05). Hatchability was not influenced by supplementing multi-enzyme mixture in the diet. The proportion of cracked and broken eggs was signed (P<0.05) improved after using multi-enzyme supplementation in the diet of breeders. In conclusion, egg production and egg mass were increased as a result of multi-enzyme preparation. Significant improvements achieved in egg shell quality led to a greater number of eggs for hatching, though hatchability itself, was not improved by multi-enzyme supplementation.
Single sample and serial measurements of osteoprotegerin level as a target of therapy in type 2 diabetes mellitus

Osteoprotegerin (OPG) is a soluble member of the tumor necrosis factor receptor superfamily, which exhibits the close link to cardiovascular (CV) disease in type 2 diabetes mellitus (T2DM). Recent clinical studies have been shown that elevated OPG might be a marker of vascular calcification / remodeling and CV events and CV mortality in T2DM without known CV disease. However, it remains unclear whether OPG would be a target for therapy of diabetics with antidiabetic drugs and statins. The aim of the mini review: to summarize knowledge with respect to OPG utilization as predictor of CV adverse effects and as a target of therapy in T2DM. The review is discussed the evidence regarding possibility to prevent microvascular and macrovascular complications in diabetics through control of OPG level as a target in therapy. Although there are not irresistible findings that the post-treatment OPG level in diabetics and CV events might be related, possibility to use OPG for risk stratification of vascular remodeling / ectopic calcification and CV-related mortality in T2DM appears to be attractive. The future investigations are needed to explain whether serum OPG would be informative for biomarker-guided therapy in T2DM individuals.
Influence of row spacing reduction on maize grain yield in regions with a short summer

(2) Abstract†n†The interest in reducing maize row spacing in the short growing season regions of Brazil is increasing due to potential advantages such as higher radiation use efficiency. This experiment was conducted to evaluate the effect of row spacing reduction on grain yield of different maize cultivars planted at different dates. The trial was conducted in Lages, in the State of Santa Catarina, Brazil, during 1996/97 and 1997/98 growing seasons, in a split-split plot design. Early (October†1 st ) and nor- mal (November†15) planting dates were tested in the main plot; two morphologically contrasting culti- vars (an early single-cross and a late double-cross hybrids) were evaluated in the split plots and three row widths (100, 75 and 50†cm) were studied in the split-split plots. The reduction of row spacing from 100 to 50†cm increased linearly maize grain yield. The yield edge provided by narrow rows was higher when maize was sown earlier in the season. Differences in hybrid cycle and plant architecture did not alter maize response to the reduction of row spacing.

PREDICTORS OF HEALTHINESS AMONG DIABETICS

Many chronic diseases like diabetes, cancer, cardio vascular diseases affect the health of the individual. Diabetes mellitus is one of the largest health care problem in the developing countries in terms of prevalence, cost and the physical and psychological burden it places on individual living with illness. So the present study aimed to find out the predictors of healthiness among diabetics. 61 diabetics and 61 Non- Diabetics were randomly selected from Baba Banda Bhadur charitable trust clinic (Rohtak). The data were collected by the Healthiness scale by Leddy (1997), General self-efficacy scale by Jerusalem and Schwarzer (1992), Resilience scale by Wagnild and Young (1993), Multidimensional Health locus of control scale by Wallston et al., (1976). The data were analyzed by using Pearson’s product moment method to see the correlation among these variables along with descriptive statistics. The data was also analyzed by regression analysis. Results revealed that resilience, chance (MHLC) and self-efficacy were significant predictors contributing 39.1% of variance in healthiness.
Assurance of Corporate Social Responsibility (CSR) reports and capital market benefits in a European setting

Companies increasingly face pressure by their stakeholders to inform them about the firm’s sustainability practices, which has led to a rising supply of corporate social responsibility (CSR) reports and external assurance on these reports. Due to its voluntary nature, lack of regulation and absence of generally accepted guidelines, the effectiveness of assurance is often criticized. Early evidence however does suggest that assurance may be beneficial to firms, but the relationship is not undisputed. In order to determine whether assurance is valued by the European capital markets, this thesis employs a sample of 439 European firms to explore the potential effect of several aspects of assurance on the cost of capital. Results show no relationships, indicating that the European capital markets do not value assurance and assurance therefore not leads to a lower cost of capital. Due to the absence of research on the effectiveness of assurance in European markets, this thesis contributes to the existing body of literature. The results of this thesis embrace the importance of increasing regulation and constructing general guidelines in order to enhance the effectiveness of assurance statements and consequently increase the credibility of CSR information.

Maize productivity as influenced by organic inputs and mineral fertilizer in a Nitisol soil in Meru South District

Declining land productivity is a major problem facing smallholder farmers in Kenya today. This decline primarily results from a reduction in soil fertility caused by continuous cultivation without adequate addition of external nutrient inputs. Improved fertility management combining organic and mineral fertilizer inputs can enable efficient use of the inputs applied and increase overall syste productivity. Field trials were established at two sites with different soil fertility status in Mucwa with the aim of determining the effects of various organic sources (tithonia, mucuna, calliandra and manure) and their combinations with mineral N fertilizer on maize grain yield and soil chemical properties. Sole tithonia and sole calliandra treatment generally recorded the highest maize grain yields for Mucwa poor and Mucwa good sites, respectively. Generally the maize grain yields were lower in the treatments with fertilizer alone compared to the treatments with organics in the two sites in the seven cropping seasons. There was a general decline in soil chemical properties over the seasons, even with the seasonal input application in both sites. Manure was superior in terms of improving soil chemical properties for instance, it supported an increase in soil pH, magnesium, potassium, calcium and nitrogen.
Epidemiological profile of snake bite at tertiary care hospital, East India

Background: Snakebite is a common medical emergency and an occupational hazard for majority of Indian population especially farmers. Epidemiological data on snake bite from the East India is sparse. Methods: This hospital based prospective study was conducted from March 2013 to February 2014. 200 cases of snakebite poisoning were admitted to the hospital during the study period. Results: Majority of victims belonged to the age group of 15-45 (60%), resident of rural areas (92%) and were involved in agricultural activities (60%). The study population was predominately bitten outdoors (66%), in the lower extremity (86%), at night (82%). Respiratory muscle paralysis (66.7%), ptosis (66.7%), coagulopathy (60%), acute renal failure (55.6%), shock (55.6%) were the signs associated with poor prognosis. Conclusions: Snakebite is an important occupational hazard, though preventable in principle remains to be one of the common medical emergencies.
The Impact of Foreign Capital Inflows, Infrastructure and Role of Institutions on Economic Growth: An Error Correction Model

This study investigates the impact of foreign capital inflows, corruption, and infrastructure on economic growth among ECOWAS members over the period 1980 to 2016. We adopt the Two-Gap model and using ECM method. The empirical results revealed long run causality between the explanatory variables and growth. And also there are short run causality between FCI, infrastructure and corruption on growth but Political stability does not cause growth in short run. Findings of the study also established a negative relationship between FDI, Infrastructure and real growth while ODA, corruption, political stability have positive impact on real growth among ECOWAS members. We recommend policy across the ECOWAS countries that will attract foreign capital inflow. The policy makers should look inwards, re-strategize and begin to formulate and implement sound and credible economic policies that will be aimed at attracting productive capital inflows into the region.
Assessment of genetic diversity of indigenous turmeric (Curcuma longa L.) germplasm from Pakistan using RAPD markers

Molecular genetic fingerprints of indigenous turmeric (Curcuma longa L.) genotypes were developed using Randomly Amplified Polymorphic DNA (RAPD) marker to elucidate the genetic diversity among the genotypes. DNA was isolated using CTAB method. The amplification was accomplished by using 10 primers and the specific PCR working program. Ten decamer-primers generated 95 RAPD fragments, of which 92 fragments were polymorphic with 96.84% of polymorphism. Some of the RAPD markers were useful for genotypes discrimination and identification. Most of the RAPD markers studied showed different level of genetic polymorphism. Amplified fragment sizes ranged from 200 to 3640 bp. Pair-wise Nei and Li’s similarity coefficient value ranged from 0.00 to 0.71 for 20 genotypes of turmeric. A dendrogram was constructed based on the unweighted pair group method using arithmetic averages. Cluster analysis of data using UPGMA algorithm placed the 20 genotypes of turmeric into four groups that are somewhat congruent with classification based on morphological characters proposed by earlier works. This analysis grouped all genotypes from Bannu with two Haripur genotypes and clearly differentiated Kasur and Bannu genotypes into separate groups. This method of analysis can be helpful in selecting diverse parents and give broadness to the germplasm base of turmeric breeding programs in the future.
