Published: December 2019

Introduction. The overwhelming number of publications contains only data on the content of individual antioxidants, but not on the overall antioxidant activity of the blood in patients with vibration disease.The aim of the study was to determine the total antioxidant activity of blood serum in patients with vibration disease.Materials and methods. Th e main group consisted of 30 people diagnosed with “Vibration disease” of 1 degree (n=21) and 2 degrees (n=9). Th e control group consisted of 30 clinically healthy men, comparable in age with the main group (p=0.66). Th e total activity of antioxidant systems of blood plasma was evaluated photometrically using the test system “Total antioxidant status-Novo” (“Vector-best”, Russia).Results. The indicator of the total antioxidant status (TAS) was 1,038±0.232 mmol/l in the examined main group, against 1,456±0.225 mmol/l in the examined control group (p<0.000001). Th e coefficient of variation (CV) in patients with vibration disease was 22.35%, 1.45 times higher than in the control group (15.45%). In the main group there was a positive correlation between age and TAS (R=0.525), in the control group there was no such relationship (R=0.095). Th e degree of decrease depended on the severity of vibration disease.Conclusions. 1. The development of vibration disease is accompanied by a decrease in the antioxidant status of blood serum. 2. Th e degree of decrease in the antioxidant status of blood serum correlates with the severity of vibration disease. 3. Reduction of TAS can serve as a pathogenetic justification of the need to include drugs and/or biologically active additives with antioxidant activity in therapy

Published: December 2019

Introduction. It is known that in industrial workers, working conditions and climatic features of the Arctic create an increased risk of occupational diseases. Th e purpose of the study was to investigate the impact of working conditions on the structure and prevalence of occupational pathology among the working population of the gas and oil producing region in the Arctic.The aim of the study is to explore working conditions, the structure and prevalence of PP in the working population of the gas-oil-producing region in the Arctic.Materials and methods. The data of social and hygienic monitoring in the section “Working conditions and occupational morbidity” of the population of the Nenets and Yamalo-Nenets Autonomous Districts from 2007 to 2017 were studied.Results. It was found that employees in the Arctic gas and oil producing region were most frequently exposed to noise (24.0%), poor microclimate parameters (10.1%), non-ionizing electromagnetic fields and radiation (9.7%). Th e combined effect of several factors was found in 24.8% of workers. Th ere were 285 patients with newly diagnosed OD, 67.0% of whom were air transport workers, and 14.4% were employed in the gas and oil industry. Th e structure of the occupational pathology was dominated by sensorineural hearing loss (77.9%). In 2017, the regional level of occupational morbidity exceeded the national level by 1.7 times, among air transport workers — by 1.9 times, while among employees of gas and oil producing enterprises it was 5.3 times less than the national industry indicator. Th e risk of OD development among air transport workers was higher than in the region as a whole (RR = 45,88; CI 38,3–54,9), in oil and gas companies workers (RR=141,0; CI 100,8–197,2) and in workers of all types of transport, except air transport (RR =68,3; CI 39,8–117,4).Conclusion. In the Arctic gas and oil producing region, most often occupational pathology is recorded among air transport workers, which necessitates the use of a comprehensive program for its prevention. It is necessary to explain the low levels of occupational morbidity in the gas and oil production and other economic activities in the region.

Purpose - to test standard firm factors and industry affiliation of firms affecting the capital structure of SMEs. Design/Methodology/Approach – the non-financial firms in Kazakhstan with all types of economic activities for 2015-2018 under consideration. In order to study the determinants of capital structure such as asset tangibility, size, growth, liquidity, profitability across the industry group of SMEs for non-financial SMEs in Kazakhstan the authors use panel data analysis. Findings - The results indicate that the main factors influencing the process of capital structure management in Kazakhstan SMEs are asset tangibility, size and profitability. It was confirmed that sectoral implications also affect the long-term debt and total debt of SMEs. Research limitation - it is necessary to provide further research concerning this topic. It is needed to study the capital structure of SMEs in the long term and across multiple countries, which will give us a more accurate concept of decisions on the capital structure taken in companies. Originality/value - the study of capital structure determinants of SMEs in Kazakhstan was not conducted yet. The empirical analysis in many aspects gives the same results as other related studies in emerging markets. However, the size has a negative relation to the capital structure, which does not correspond to most empirical studies.

Authors: Abbas Ishraq k. , A. Rajab Nawal , A. Hussein Ahmed 
Published: December 2019

Darifenacin hydrobromide (DH) is the more recent uroselective M3 receptor antagonist for treating uncomplicated overactive bladder (OAB). This study was aimed to formulate DH as fast dissolving buccal films (FDBFs) using a solvent casting method to enhance patient’s compliance.
Films were prepared by using polyvinyl alcohol (PVA) as a film forming polymer. Different types and concentrations of superdisintegrants (croscarmellose sodium, sodium starch glycolate, indion 414) were used to select the best formula by studying the physicochemical properties of the films, disintegration time (DT) and percent drug release.
The results revealed that formula (F9) that containing 7.5mg DH, 2%w/v PVA, 30%w/w glycerol, 0.5%w/v tween 80, 4%w/w indion 414 was the preferred formula. F9 showed the shortest in-vitro disintegration time (31.28sec). In-vitro dissolution profile showed the lowest T80% of the drug in 3.05 min and the highest release of the drug (94%) within 5 min (D5min %).
It was concluded that the FDBFs of DH could be considered as a promising drug delivery system with an enhanced disintegration and dissolution rate and better patient compliance.

Bayesian Analysis of the Discrete Two-Parameter Bathtub Hazard Distribution
Authors: SARHAN Ammar 
Published: December 2019

A new discrete two-parameter bathtub hazard distribution is proposed by Sarhan \cite{Sarhan-2017}. This paper uses Bayes method to estimate the two unknown parameters and the reliability measures of this distribution. The joint posterior distribution of the model parameters cannot be obtained in a convenient form. Therefore, numerical techniques are needed. We apply four Bayesian numerical methods to get random draws from the joint posterior distribution to be used to estimate the model parameters and its reliability measures without deriving the actual joint posterior distribution. It is assumed here that the two model parameters are priori independent random variables with beta and gamma distributions. Two scenarios for the hyperparameters are applied to compare their contributions on the Bayesian inferences. Two real data sets are re-analyzed using the Bayesian techniques applied here. A simulation study is performed to investigate the properties of the methods applied.

Published: December 2019

In this work, we introduce the notion of 2-absorbing semiprimary fuzzy ideal which is a generalization of semiprimary fuzzy ideal. Let $ R $ be a ring. Then the nonconstant fuzzy ideal $ \mu $ is called a 2-absorbing semiprimary fuzzy ideal if $ \sqrt{\mu } $ is a 2-absorbing fuzzy ideal of $ R $. Furthermore, we give some fundamental results concerning these notions.
