subject analysis of the potential of spontaneous combustion in coal layers with analytical and numerical methods has been always considered as a difficult task because of the complexity of the coal behavior and the number of factors influencing it. empirical methods, due to accounting for certain and specific factors, have not accuracy and efficiency for all positions. the rock engineering syst...

The time evolution of the quantum entropy in a coherently driven threelevel quantum dot (QD) molecule is investigated. The entanglement of quantum dot molecule and its spontaneous emission field is coherently controlled by the gat voltage and the intensity of applied field. It is shown that the degree of entanglement between a three-level quantum dot molecule and its spontaneous emission fields...

Background and Objective: Epilepsy as a chronic neurological disorder causes inherent seizures and learning and memory failure. Since there is no acceptable control of seizures in some patients with the current recommended drug therapy, new medications with different mechanisms of action are needed. Here, the beneficial effect of hepatocyte growth factor (HGF) was evaluated in an experimental m...

Abstract The spontaneous emission spectrum from a driven three-level atom placed inside a double-band photonic crystal has been investigated. We use the model which assumes the upper levels of the atomic transition are coupled via a classical driving field. The transition from one of the upper levels to lower level couples to the modes of the modified reservoir, and the transition from the oth...

      The effects of hydroalcoholic extract of Peganum harmala seeds (EPS) on spontaneous rhythmic contractions of isolated rat uterine was investigated in this study. EPS was tested on the isolated uterus and endometrium free (i.e. stripped myometrium) preparations. EPS was found to exhibit significant spontaneous contractions of the uterus and stripped myometrium relative to the solv...

The causes of periorbital ecchymosis are traumatic and non-traumatic head and neck insults. This report deals with a non-traumatic bilateral spontaneous periorbital ecchymosis in pregnancy.The case studied was a 24-year-old woman in her eighth month of pregnancy who realized her spontaneous ecchymosis around both eyes which was more prominent in the right eye 12 hours after vomiting. She did no...

We summarize some of the most frequenthly used rodent animal models of temporal lobe epileps and the impact of chemoconvulsants on them. Temporal lobe epilepsy is the most common epilepsy in humans in which seizures spread to the neighboring cortiase and hippocampal neuron loss and other neuropathological take place. Temporal lobe epilepsy and the other form of epilepsy cannot acquired in chini...
