We present new results of observations of the 6708 Å line in twelve CP stars made with three telescopes: the ESO CAT telescope, the Crimean Observatory (CrAO) 2.6-m telescope, and the Nordic Optical Telescope (NOT). Unique profile and wavelength variations of the line at 6708 Å were discovered in two stars, HD 60435 and HD 83368. We present arguments in favour of the identification of this feat...
Objective: Gastric cancer is one of the most common malignant tumors. Non-inversional tool could improve the diagnosis and treatment of the cancer. The aim of this study was to evaluate the diagnostic value of diffusion-weighted imaging (DWI) for histological factors and Ki-67 antigen labelling index (LI) in gastric cancer. Methods: Eight-four DWI images of gastric cancer were analyzed retrospe...

In the present work, the solid-state dispersion method has been used to stabilize ZnOon Todorokite (TD). ZnO/TD catalysts have been characterized by SEM and XRD. Optimum process conditions were determined for the removal of Cr(VI) from water using the Taguchi fractional design method. Four controllable factors containing pH, photocatalyst amount, irradiation intensity, and <em...
Geologic and pedologic controls are the main factors determining the distribution of elements in natural soil environments. In order to assess the role of these factors in the content and distribution of major elements of soil, six parent materials including phyllite (Ph), tonalite (To), periditite (Pe), dolerite (Do), shale (Sh) and limestone (Li) were selected in Fuman-Masule region. Soil gen...
