Abstract Many different fields benefit from the usage of light sources emitting in mid-infrared wavelength range (2–10 µ m). A rising need for precise and fast mid infrared (mid-IR) is reflected development a high-power, picosecond mid-IR source capable generation at high repetition rates. In this work, we present optimization an optical parametric generator, pumped by 3 W portion total power Y...

BACKGROUND Transpulmonary thermodilution (TPTD) derived parameters are used to direct fluid management in ICU-patients. Extravascular lung water EVLW and its ratio to pulmonary blood volume (pulmonary vascular permeability index PVPI) have been associated with mortality. In single indicator TPTD pulmonary blood volume (PBV) is estimated to be 25% of global end-diastolic volume (GEDV). A recent ...

BACKGROUND: Incidence of epilepsy in elderly patients is higher than in any other group. The diagnosis of epilepsy in old age is particularly challenging and is often overlooked or missed. Selection of appropriate antiepileptic drugs (AEDs) for this group of patient also requires more attention than younger patients. OBJECTIVE: To summarise the clinical presentation, aetiology, diagnosis, treat...

مقدمه: استرس اکسیداتیو به‌عنوان یک عامل ایجاد‌ کننده ناباروری مردانه شناخته شده و آنتی اکسیدانت‌ها نیز به‌عنوان عامل مؤثر در مقابل استرس اکسیداتیو مورد توجه قرار گرفته‌اند. بنابراین مطالعه حاضر با هدف بررسی ارتباط آنتی اکسیدانت‌های دریافتی رژیم غذایی با پارامترای آنالیز اسپرم انجام شد. روش‌کار: این مطالعه توصیفی- همبستگی در سال 1395 بر روی 190 نفر از مردان مراجعه‌کننده به مرکز باروری و ناباروری...

Sesame is one of the oldest crops in the world that is commonly cultivated in arid and semi-arid due to high oil seeds (42-52%). In order to determine the effects of water deficit (55, 75 and 85 percent evacuation of soil water) on genotype sesame (Varamin, Naztakshakhe, Oltan and Yekta), a field experiment was conducted using a split-plot in randomized complete design with three replication at...

An electric multiple unit (EMU) high-speed train is the dynamic load that degrades power quality in an railway system. Therefore, a improvement system using active filter (APF) must be considered. Due to oscillating current condition, fast and accurate harmonic current-tracking performance required. As such, this paper proposes design of model predictive control (MPC) since minimization cost fu...
