The Role of Psychological Resilience in Athletic Injury Recovery and Performance

The essential aim of this research study is to determine the role of psychological resilience in athletic injury recovery also that performance. This research study is based on the primary data analysis for measuring the research study using questions wise data and measuring the analysis through smart PLS software and generating informative results. The descriptive statistic analysis, the indicator correlation, the significant analysis, and the co-linearity statistic analysis between them. The result also presents that smart PLS Algorithm model between dependent and independent variables. Psyc ...Более

The effects of the investment decisions of telecommunications firms on their financial performance during the COVID-19 pandemic

Gökhan ÖZER

In this paper we examine how the financial performance of telecommunications firms is affected by the COVID-19 pandemic, and investigate the role of capital expenditures in this relationship. The full sample consists of 383 unique telecommunications firms from 72 countries. Empirical models are estimated using ordinary least squares regression with the Driscoll–Kraay standard errors method. We find that the financial performance of telecommunications firms, on average, decreased slightly during the pandemic period. However, firms with higher capital expenditures have increased their financial ...Более

The effect of drinking water and isotonic sports drinks in elite wrestlers

Serdar GERİ

The purpose of this study was to investigate the effects of sports drinks (isotonic) and water consumptions of the elite wrestlers during the exercise. Eighteen-trained elite wrestlers participated in this study. The subjects were divided into two groups according to their body-weight and were also given either water or isotonic sports drink. Water and sports drinks get rid of the dehydration during the trainings (P>0.05). Blood samples were taken before and after the exercises,and were analyzed for Sodium (Na), Potassium (K) and Chlorine (Cl). Body temperatures of subjects were measured as ºC ...Более

Preparation of molecularly imprinted PDMS elastomer for selective detection of folic acid in orange juice

Nahit AKTAŞ

Herein, it is reported an effective method to prepare novel molecularly imprinted polymers (MIP) on poly(dimethylsiloxane) (PDMS) elastomer via a combination of non-covalent imprinting approach and surface initiated reversible addition fragmentation chain transfer (SI-RAFT) polymerization for sensitive and selective detection of folic acid (FA). For this purpose, 2-(2-Methoxyethoxy) ethyl methacrylate (MEOMA), ethylene glycol dimethacrylate (EGDMA), azobisisobutyronitrile (AIBN), FA and dimethylsulfoxide (DMSO) were used as functional monomer, cross-linker, initiator, template molecule, and po ...Более

Urea Uptake and Release by Novel Macrogels from Dimethylacrylamide

Nahit AKTAŞ

A novel macrogels poly(N,N-Dimethylacrylamide) (p(DMAAm)) and its derivatives were synthesized from DMAAm for use in urea uptake and release. p(DMAAm) surface was modified by NaOH and HCl to obtain p(DMAAm)/NaOH and p(DMAAm)/HCl, which are negatively and positively charged, respectively. The dynamic swelling behaviors, water retention and pH sensitivities of the macrogels were studied. It was found that all macrogels exhibited the equilibrium swelling ratio (SR) in the range 1068-1451%. Swelling kinetics showed that the macrogels possessed Fickian diffusion behavior while the diffusion coeffic ...Более

The origins and spread of domestic horses from the Western Eurasian steppes

Kubatbek TABALDİYEV

Analysis of 273 ancient horse genomes reveals that modern domestic horses originated in the Western Eurasian steppes, especially the lower Volga-Don region. Domestication of horses fundamentally transformed long-range mobility and warfare(1). However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling(2-4) at Botai, Central Asia around 3500 bc(3). Other longstanding candidate regions for horse domestication, such as Iberia(5) and Anatolia(6), have also recently been challenged. Thus, th ...Более
