many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of suc...
The article presents the results of marine geophysical research ancient port area Chersonesos located in Karantinnaya Bay, which is now about 2–4 m below sea level. Set methods along with archeological and hydroacoustic types work includes bottom electrotomography, has not been used until practice underwater archeology to map remains structures buried by sediments. Based on side-scan sonar prof...
Extended Abstract 1-Introduction Interdisciplinary studies play an important role in answering engineering questions. Identifying the characteristics of alluviums, underground water exploration and minerals, along with geotechnical studies in the construction of heavy structures are just some of these applications. Following the increasing drying of Lake Urmia, various research has been conduc...
در حال حاضر چندین روش برای اندازه گیری چربی زیرپوستی بدن در حوزه های بالینی وجود دارد ، مانند : magnetic resonance imaging(mri)، (computer tomography(ct، ultrasound imaging(us) ، dual energy x-ray absorptiometry(dexa). این روش ها بطور وسیعی در حوزه های بالینی به عنوان وسایل دقیق و مفید ، مورد استفاده قرار می گیرند. به هر حال این روش ها محدودیت های زیادی مانند هزینه بالا و یا خطر تابش اشعه را دا...

Multiple myeloma causes major morbidity resulting from osteolytic lesions that can be detected by metastatic bone surveys. Magnetic resonance imaging and positron emission tomography can detect bone marrow focal lesions long before development of osteolytic lesions. Using data from patients enrolled in Total Therapy 3 for newly diagnosed myeloma (n=303), we analyzed associations of these imagin...
Background & Aims : Hair follicle morphogenesis is controlled by complex reprocical ectodermal–mesenchymal interactions regulated by molecular mechanisms. In addition, glycoconjugates are known to be important for molecular interactions during developmental processes. The aim of this research was to study glcoconjugate terminal sugars distributions and changes during rat hair follicle morph...
We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...
