The Mössbauer effect was first described by Rudolf Mössbauer in 1957. The effect describes how nuclei can emit or absorb gamma-rays without recoiling under certain circumstances. When a free nuclei emits or absorbs gamma-rays, it recoils as a result of energy and momentum conservation. As a result, if a free nucleus undergoes a transition from an excited state to its ground state by emitting ga...

Neurobiological studies demonstrate the amygdala’s role in emotional memory, and psychological studies suggest a particular pattern: enhanced memory for the gist but not the details of complex stimuli. We hypothesized that these two findings are related. Whereas normal (n 5 52) and brain-damaged (n 5 22) controls showed the expected enhancement of gist memory when the encoding context was emoti...

Shape oen has a decisive inuence over the properties and applications of monodisperse nanoparticles. In addition, size is another important factor controlling the properties of the nanomaterials owing to various connement effects. Therefore, the synthesis of diverse, high-quality nanoparticles with tunable shapes and sizes has become a challenging issue and drawn considerable attention. Morp...

Neurons have been neglected as cells with a major immune-regulatory function because they do not express major histocompatibility complex class II. Our data show that neurons are highly immune regulatory, having a crucial role in governing T-cell response and central nervous system (CNS) inflammation. Neurons induce the proliferation of activated CD4+ T cells through B7-CD28 and transforming gr...
متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
