The pollution of surface water by recently used pesticides in Mekong Delta, a main drinking water source, is increasing both on the concentration residues and the polluted area [1,2]. Nanofiltration (NF) is arising as the most appropriate method for removal of pesticides with not only a good efficiency but also low energy consumption in comparison with other pressure-driven membrane processes [...

background: human cornea expresses functional fas-ligand capable of killing fas+ activated lymphocytes. fas expression is partly regulated by -670 a/g polymorphism in the promoter region of fas gene. objective: the aim of the present study is to determine the association between fas-670a/g polymorphism and survival of corneal transplantation. methods: in 276 graft recipients who mainly underwen...

The main objectives of this study were to remove surface-active agents and to predict the adsorption rejection models.  The effects of surfactant concentration and PAC amount on the adsorption were determined. For both surfactants, It was found that the adsorption values also increased when PAC amount increased. It was observed that the rejection values are different for the adsorption of C...

The article aims to test the weak form of efficiency a sample public companies on Bulgarian Stock Exchange (BSE) for period from October 2000 June 2020 basis weekly returns. 9 and SOFIX index meet set criteria inclusion in sample. Descriptive characteristics returns, autocorrelations extended Dickie Fuller (ADF) stationary are presented. methodology Runs Test is considered. results reject some ...

To meet the growing demands for service provisioning using wireless access, efficient utilization of the available radio spectrum is a key issue of great importance. To achieve high spectrum efficiency, use of spectral efficient modulation methods in combination with tight physical channel reuse are anticipated in future cellular communication systems. As a consequence, the link performance and...

for monitoring of renal transplant function, serum b2m was evaluated in 23 recipients. according to clinical diagnosis the patients were in four groups: 1) successful renal transplant the mean concentration of sb2m pretransplantation was 73.1±26.1 mg/l but decreased to nearly normal level (4.43±1.17 mg/l) within 24-48h and then reached to 3.1 mg/l duting 20 days after transplantation. 2) renal ...

introduction: acute rejection of renal transplant is a serious and common systemic inflammatory disorder which leads to decreasing half-life of transplant organ. current diagnoses method is an invasive biopsy procedure on allogtraft kidney. therefore, applying a novel and noninvasive diagnostic method such as granzym b level in acute renal transplantation could help patients and improves surviv...

This paper analyses the application of hierarchical classifiers based on the k-NN rule to the automatic classification of handwritten characters. The discriminating capacity of a k-NN classifier increases as the size of the reference pattern set (RPS) increases. This supposes a problem for k-NN classifiers in real applications: the high computational cost required when the RPS is large. In orde...

Commitment Problems and Shifting Power as a Cause of Conflict Robert Powell Decades ahead of his time, Thomas Schelling emphasized that “most conflict situations are essentially bargaining situations” (Schelling 1960, 5). Building on this, formal work on the causes of war in political science since the mid-1990s has generally framed the problem in terms of an “inefficiency puzzle” akin to Hick’...
