Purpose This study aims to investigate the determinants of banking stability in the case of QISMUT + 3 countries (Qatar, Indonesia, Malaysia, United Arab Emirates, Turkey, Pakistan, Kuwait and Bahrain). Both profitability of banks and non-performing loans were treated as dependent variables. Three variations are examined, the sample as a whole and separated to conventional banks (CBs) and Islamic banks (IBs). Design/methodology/approach Data from 208 banks, both IBs and CBs, were used from 2011 to 2018, after global financial crisis period. Two-step system generalized methods of moments and both feasible least squares and panel-corrected standard error models were used to ensure test the data. Findings Results suggest that both financial vulnerability and profitability affect each other in both banking systems. In addition, capital adequacy has a positive link with both dependent variables. Corruption varied and followed expectations but for the case of CBs alone with an unexpected negative relationship with profitability. Practical implications The findings are expected to help bankers, investors, academics and policymakers gain a better understanding of Islamic banking. The findings would be useful in developing policy for the development of the banking industries in these countries. Originality/value This study contributes to existing literature in three ways. First, this study investigates the factors influencing banking non-performing loans for a new class of countries – QISMUT + 3 within 2011–2018 period. Second, only a few studies use such a period, which is after the global financial crisis period. Finally, new indicators are used to determine the non-performing loans and profitability of both types of banks, such as Muslim Share and Share of IBs.

This paper is devoted to study on the sediment runoff of the Ile River downstream. The article analyses the Kapshagai reservoir impact on the regime and characteristics of the sediment runoff in the Ile River downstream before and after construction of the reservoir in 1970. Along with the calculation of characteristics of sediment runoff, an assessment of the amount of the suspended sediment, which is in the bowl of the reservoir, was shown. Furthermore, the impact reservoir on the granulometric composition of the suspended and bed sediment of Ile River was calculated.
