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 ...More

İhsan KISADERE | Ertan ORUC | Nariste KADIRALİYEVA

The aim of the study is to evaluate the relation of serum mineral levels (Ca, Mg, P) with intraocular pressure (IOP) and jumping performance of horses. Twenty-four jumping horses, actively participated in the competition, were selected from a horse sport center in Bishkek and used for this study. Intraocular pressures in both eyes of each horse were measured by using a tonometer and blood samples were collected for analyzing serum Ca, P and Mg levels. IOP, Serum Ca, Mg and P values were measured in normal ranges in all jumping horses. Although Ca and P levels were found different in statistic ...More

Effects of Aflatoxin on Some Haematological Parameters and Protective Effectiveness of Esterified Glucomannan in Merino Rams

Nurcan DÖNMEZ | Hasan Hüseyin DÖNMEZ | İhsan KISADERE

The objective of the present study was to evaluate the toxic effects of aflatoxin on some hematological parameters and to determine the preventive effectiveness of added glucomannan. In the study, 32 Merino rams were used, and the rams were separated equally to four groups as control (C), glucomannan (G), glucomannan + aflatoxin (AG), and aflatoxin (A). Erythrocyte, leukocyte count, hemoglobin, and hematocrit levels were decreased in A group compared with the other groups, and there was a reduction in similar parameters in AG group compared to control values. On the other hand, these parameter ...More

Effects of Glucomannan on the Sacculus Rotundus and Peripheral Blood Lymphocytes in New Zealand Rabbits during Aflatoxicosis

Hasan Hüseyin DÖNMEZ

This study was aimed to determine the effects of the glucomannan added to aflatoxin- (AF-) contaminated diet on the sacculus rotundus and peripheral blood lymphocytes of New Zealand rabbits by histological and enzyme histochemical methods. Twenty-four adult rabbits of both sexes were divided into four equal groups, namely, as control, glucomannan 0.2 g/day, AF 125 μg/kg/day, and glucomannan combined with AF. The animals in all groups were treated for 12 weeks by the above-mentioned diet. When compared to control, AF-treatment caused significant decrease in alpha-naphthyl acetate esterase- (ANA ...More

Taguchi optimization of automotive radiator cooling with nanofluids

Kasım BAYNAL

Considering the influences of the heat transfer rate in automotive radiators on several aspects such as engine performance, fuel economy and available space for components, the present study numerically investigates the impacts of different nanofluids on the heat transfer and pressure drop in an automotive radiator. Four different parameters each having four levels are taken into consideration, which are nanoparticle volume fraction (phi 0.1, 0.3, 0.7, and 1), Reynolds number (Re 9350, 13,800, 18,500 and 23,000), type of base fluid (EG20, EG40, EG60, and water) and type of nanoparticle (Fe3O4, ...More

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

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 ...More

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 ...More
