Objectives: Electrical appliances are source of radiofrequency radiation (RFR). The effects RFR on the organism not fully understood. Endoplasmic reticulum (ER) stress is appeared by accumulation misfolded proteins in ER lumen. aim this study was to investigate 900 and 2100 MHz exposure pathway rat thymus. Methods: Rats were divided into six groups: 1 week (w) 10 w Sham rats kept plexiglass tub...

Intercropping, mixed cropping, and rotation are commonly applied some of the oldest crop production techniques to improve soil structure nitrogen status. While takes generally two-season with one triticeae legume, inter-and cropping place within same season. Among many advantages legume most important is sustainable use resources reduced input cost. Numerous studies evaluated effect inter -and ...

Microbial fuel cells (MFCs) are a kind of bioreactor for generating electricity, facilitated by exoelectrogens while treating wastewater. The present article focuses on the performance an air cathode plexiglass MFC in terms chemical oxygen demand (COD) removal efficiency and power output performing two sets experiments. proton exchange membrane electrode materials were Nafion 117 carbon felts, ...

The underwater robot is part of a project with “terrestrial–maritime” collaborative robots, whose mission recognition and rescue. From structural point view, some small changes were made in this study to the original robot. These consisted making supports hold two plexiglass tubes, since tube containing battery system larger. A larger was chosen because aim increase travel autonomy mini remotel...

Industrial development and extensive use of heavy metals have led to the problem of environmental pollution. Nickel compounds are toxic to plants and have detrimental effects on their growth. Valerian is a plant used in herbal medicine. Considering the hazards of nickel, various methods have been developed to remove this contaminant from herbs irrigation wastewater, including the common chemica...

During the evaluation of Young’s modulus by vibroacoustic methods, it is usually assumed that Poisson's ratio known. This assumption based on a reasonable tolerance methods to an inadequate estimate ratio. However, most studies do not consider influence error in estimation Young's error. Moreover, total typically does include any parametric analysis at all. Therefore, new method proposed provid...

Long-span shell structures are widely used in various industries. To ensure safe modes of operation, it becomes necessary to develop calculation methods and study for buckling under the applied load. Traditionally, these data obtained using analytical semi-analytical methods. This paper presents a description process determining critical loads obtaining “load-deflection” dependences, taking int...
