From Oct. 2000 until July 2001 the H1 experiment at the e-p collider HERA has been considerably upgraded for higher luminosity running. The required modifications for the H1 detector control system have been the object of the H1 detector control and monitoring project. A variety of subsystems, some from the early 1990s as well as new subsystems with modern design and technology are to be contro...

This study was conducted to determine the histopathological and biochemical effects of humic acid on cadmium stress in liver and kidney tissues of Salmo trutta fario, L. The fish were treated in four groups as follows and were exposed to chemicals for 7 days: control (C), cadmium (2 ppm) (Cd), humic acid (5 ppm) (HA) and humic acid + cadmium (Cd + HA). At the end of the experimental period, liv...

In this study, the effects were investigated of salinity, foliar and soil applications of humic substances on the growth and mineral nutrients uptake of Corn (Hagein, Fardy10), and the comparison was carried out of the soil and foliar applications of humic acid treatments at different NaCl levels. Soil organic contents are one of the most important parts that they directly affect the soil ferti...

The potential for humic substances to stimulate the reduction of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) was investigated. This study describes a novel approach for the remediation of RDX-contaminated environments using microbially mediated electron shuttling. Incubations without cells demonstrated that reduced AQDS transfers electrons directly to RDX, which was reduced without significan...

This paper deals with the modeling of punching shear failure in reinforced concrete slabs using nonlinear finite element analysis. The 3D finite element analyses (FEA) were performed with the appropriate modeling of element size and mesh, and the constitutive modeling of concrete. The FE numerical models are validated by comparing with the experimental results obtained from tested specimens and...
