In this paper, a new model based on the thevenin equivalent circuit for investigating the ultra-saturation phenomenon during the energization of a loaded power transformer is presented and its effect on the differential protection of the transformer is considered. The ultra-saturation phenomenon causes the mal-operation of the power transformer differential protection. So, the description a...

Background: Muscle channelopathies such as paramyotonia, hyperkalemic periodic paralysis, and potassiumaggravated myotonia are caused by gain-of-function Na channel mutations. Methods: Implementation of a threedimensional radial Na magnetic resonance (MR) sequence with ultra-short echo times allowed the authors to quantify changes in the total muscular Na signal intensity. By this technique and...

UNLABELLED BACKGROUND An association between fluid intake and limb swelling has been described for 100-km ultra-marathoners. We investigated a potential development of peripheral oedemata in Ironman triathletes competing over 3.8 km swimming, 180 km cycling and 42.2 km running. METHODS In 15 male Ironman triathletes, fluid intake, changes in body mass, fat mass, skeletal muscle mass, limb ...

Recently, we reported that mutation A1529D in the domain (D) IV P-loop of the rat skeletal muscle Na(+) channel mu(1) (DIV-A1529D) enhanced entry to an inactivated state from which the channels recovered with an abnormally slow time constant on the order of approximately 100 s. Transition to this "ultra-slow" inactivated state (USI) was substantially reduced by binding to the outer pore of a mu...

purpose the aims of the present study were to investigate (i) the changes in participation and performance and (ii) the gender difference in triple iron ultra-triathlon (11.4 km swimming, 540 km cycling and 126.6 km running) across years from 1988 to 2011. methods for the cross-sectional data analysis, the association between with overall race times and split times was investigated using simple...

background: the possible role of cochlear function in tinnitus generation is still a matter of debate. to assess the role of outer hair cell dysfunction in tinnitus and its possible relationship with ultra-high frequency (uhf) hearing sensitivity, transient evoked otoacoustic emissions (teoae) and uhf hearing thresholds were investigated in normal hearing individuals with and without tinnitus. ...

regarding many disadvantages of traditional method to produce concentrated yoghurt, several attempts have been done for mechanization of process in industrial scale. using membrane systems especially ultra filtration is one of these methods. in this survey, method to produce direct concentrated yoghurt, fresh milk was concentrated to 19% snf by ultra filtration method then diluted to 13 and 16 ...
