Improving the efficiency of spin generation, injection, and detection Girls Spring Dressy Set remains a key challenge for semiconductor spintronics.Electrical injection and optical orientation are two methods of creating spin polarization in semiconductors, which traditionally require specially tailored p-n junctions, tunnel or Schottky barriers.Al
In this paper a robotic arm is modelled by a double pendulum excited in its Baskets base by a DC motor of limited power via crank mechanism and elastic connector.In the mathematical model, a chaotic motion was identified, for a wide range of parameters.Controlling of the chaotic behaviour of the system, were implemented using, two control technique
In recent years, due to the globalization of food trade and certified agro-food products, the authenticity and traceability of food have received increasing attention.As a result, opportunities for fraudulent practices arise, highlighting the need to protect consumers from economic and health damages.In this regard, specific analytical techniques h
Venous blood had been collected from sexity women with habitual abortion from Thi-Qar Governorate cities to study and evaluate the prevalence of Cytomegalovirus infection and from Pizza Pan Racks twenty healthy looking women as control.The test performed using ELISA method to detect the IgM and IgG antibodies Baskets in patients and control sample
