Atrial flutter with 1:1 atrioventricular conduction is a cardiac arrhythmia difficult to diagnose, fatal in many cases, and unmanageable with drug therapy.A number of 17 patients presenting with this disease was studied.A percentage of 70.6 % presented with throbbings, 64.7 % with syncope and important symptoms such as dizziness, sweating, and Meta

Active clamp forward (ACF) converters are being extensively applied to auxiliary power modules (APMs) in electric vehicles (EVs) to minimize the use of components and maximize efficiency.Existing ACF converter designs disregard Metal Desk Lamp (1/CN) the parasitic characteristics of the components and the leakage inductance of the transformer, resu

Dental amalgam is still the most useful restorative material for posterior teeth and has been successfully used for over a century.Dental amalgam has been widely used as a direct filling material due to its favorable mechanical properties as well as low cost and easy placement.However, the mercury it contains raises concerns about its biological to

Insect immunity is assorted into humoral and cellular immune reactions.Humoral reactions involve the grip with wire regulated production of anti-microbial peptides, which directly kill microbial invaders at the membrane and intracellular levels.In cellular immune reactions, millions of hemocytes are mobilized to sites of infection and replaced by h

It is shown that flame spread rate can Dust Container be high and comparable with velocities of flame propagation in the stoichiometric homogeneous gas mixture.The flame spread rate depends on velocity of oxidizer.It can either increase or decrease with arise of oxidizer velocity, depending on the oxygen content.The flame surface is significantly d
