Abstract The paper describes a semiconductor picosecond pulse generator that can be used to calibrate capacitive high voltage sensors of MV range. is designed as base unit, which external converters are connected. In the devices – first opening switch (SOS) and then sharpener (SS) generate an output with rise time 220 ps subsequent flat-top 2 ns in duration. amplitude around 1 kV across 50 Ω lo...
Microscale laser peen-forming (μLPF) is an innovative process in which compressive residual stress is induced into the treated surface to improve fatigue life of the micro scale metallic parts and meanwhile shape the parts with a controlled bending deformation. In this work, dynamic deformation in μLPF of single crystal aluminum is investigated. A finite element model based on meso scale crysta...
bee stings are commonly encountered worldwide. various manifestations after bee sting have been described including local reactions which are common, systemic responses such as anaphylaxis, diffuse intravascular coagulation and hemolysis. we report a case of a 74-year-old man who developed neurologic deficit 5 hours after bee stings, which was confirmed to be left frontal infarction on brain ct...
According to the suddenly compression of the matters in some regions of the compressible fluids, the density and temperature suddenly increases, and shockwaves can be produced. The cooling of post-shock region and non-idealness of the equation of state, $p=(k_B/mu m_p)rho T (1+brho) equivmathcal{K}rho T (1+eta R)$, where $mu m_p$ is the relative density of the post-shock gas and $Requiv rho_2 /...
Membrane bioreactor (MBR) is an efficient wastewater treatment technology, which produced by combining membrane technology and biological has the characteristics of stable water quality shock load resistance, been widely used in domestic treatment. Anaerobic ammonia oxidation (ANAMMOX) a new type denitrification with advantages low energy consumption, oxygen demand, carbon source saving good ec...
Fluctuations in housing prices in recent years in Iran has always been one of the most important economic issues on the economic welfare changes affect lifetime. In this paper, the effects of housing on the dynamics of income generations age is examined. This phenomenon type of model is designed to assess the generation of data building. The model is designed household budget generations by com...
Background: Spasticity is a common motor impairment in patients with stroke that not only has a negative impact on the patient’s quality of life but also has high economic burdens for society. Recently the application of shock wave therapy has attracted considerable attention as a safe and effective method in treatment of spasticity. The objective of the present study was to investigate the eff...
Background and purpose: Follicular atresia is a natural phenomenon throughout growth and development, but in excessive cases it causes disorders in the ovarian function which is the commonest cause of infertility. Outbreak of depression in women is twice as much as men. Electric-shock therapy could be used in the treatment of depression resistant to drugs. However, it has some side-effects. T...
Zebrafish (Danio rerio Hamilton) are increasingly used as a model to study the effects of chronic stress on brain and behaviour. In rodents, unpredictable chronic stress (UCS) has a stronger effect on physiology and behaviour during the active phase than during the resting phase. Here, we applied UCS during the daytime (active phase) for 7 and 14 days or during the night-time (resting phase) fo...
