normal 0 false false false en-us x-none ar-sa back ground: considering the high prevalence of congenital hypothyroidism (ch) in isfahan, the intelligence quotient (iq) of children with ch and the effect of diagnostic and treatment variables on it were investigated during the ch screening program. materials and methods: a total of 120 children in three studied groups were studied in this compara...

a two-variable integrate and fire model is presented to study the role of transient outward potassium currents in producing temporal aspects of dorsal cochlear nucleus (dcn) pyramidal cells with different profiles namely the chopper, the pauser and the buildup. this conductance based model is a reduced version of km-lif model (meng & rinzel, 2010) which captures qualitative firing features of a...

This paper presents an algorithm for adaptive determination of the dead timeduring transient arcing faults and blocking automatic reclosing during permanent faults onoverhead transmission lines. The discrimination between transient and permanent faults ismade by the zero sequence voltage measured at the relay point. If the fault is recognised asan arcing one, then the third harmonic of the zero...

Along with the known risk factors of cardiovascular diseases (CVDs) constituting metabolic syndrome (MS), gut microbiome and some its metabolites, in particular trimethylamine-N-oxide (TMAO), are actively discussed. A prolonged stay under natural hypoxic conditions significantly multi-directionally changes ratio strains their metabolites feces blood, which is basis for using hypoxia preconditio...

neonatal respiratory distress is a very common problem in our practice. the causes may be respiratory, cardiovascular, central, metabolic, haematological and surgical. the cause of distress due to transient myocardial depression is not very common in mild asphyxia. we present a case having transient myocardial depression with severe respiratory distress and features of shock in a mild asphyxiat...

Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...

This paper presents a new composite index to analyze power system transient stability. Contingency ranking in power system transient stability is a complicated and time consuming task. To prevail over this difficulty, various indices are used. These indices are based on the concept of coherency, transient energy conversion between kinetic and potential energy and three dot products of the s...
