Industrial and experimental induction furnaces are used for melting various types of iron ingots, returned scraps and DRI sponge pellets to produce high purity cast - iron and steel heats. The lowest consumption of electrical energy determined for continuous feeding operation is 0.3 KWH/Kg for the production of cast - iron in a 1.5 - ton industrial furnace and 0.45 KWH/Kg for the production of ...

Experimental autoimmune encephalomyelitis (EAE) is a T cell-mediated disease initiated by antigen-specific CD4(+) T cells. Signaling through CD28 is a critical second signal for activation of T cells, and CD28 knockout (CD28KO) mice have been reported to be resistant to induction of EAE. We now report that CD28KO mice have no intrinsic defect in mediating disease, because they developed EAE aft...

A LTHOUGH myelofibrosis with myeloid metaplasia ( MMM ) was first described nearly one hundred years ago, the etiology of this disturbance remains uncertain.1 Two interpretations have been offered: first, that there is a primary insult to bone marrow resulting in necrosis and necrobiosis followed by a reparative stage of fibrosis of marrow and compensatory cxtramedullary hematopoiesis in the li...

Multiple coupled circuit modeling of squirrel-cage induction motors, or winding function approach is the most detailed and complete analytical model used to analyze the performance of the faulty induction motors. This paper extends the above-mentioned model to a saturable model including variable degrees of the saturation effects using an appropriate air gap function and novel techniques for lo...

shaded pole induction motors, despite the simplicity and low cost, are difficult to analyze particularly in the equivalent circuit methods, due to the asymmetric structure, saturation, harmonics, inaccurate estimation of leakage inductances and skew. hence, 3d numerical methods could be very useful in the design and optimization stage. this paper presents the 3d transient finite element analysi...

Objective : Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders that can lead to irregular menstrual cycles and hyperandrogenism. Reduced levels of progesterone and increased estrogen in these women can perpetually stimulate the endometrial tissue of the uterus. In this study, the effect of PCOS induction was studied using estradiol valerate. MaterialsAndMethods Adult ...

Nowadays study of input voltage quality on induction motors behavior has become a controversial subject due to the wide application of these motors in the industry. The impact of grid voltage fluctuations on the performance of induction motors can be included in this area. The majority of papers devoted to the influence of voltage fluctuations on the induction motors are focusing only on the so...

Operation of any kind of machinery is always connected to efficiency and losses. The part of energy is always being dissipated to the surroundings. In the case of electric machines the losses result in heat generation. Present contribution introduces the numerical method for predicting and analysing the heat transfer including conduction, convection, and radiation at the specific operating regi...
