What are the mechanisms by which behavior is organized sequentially over time? The recently developed mid-session reversal (MSR) task offers new insights into this fundamental question. The typical MSR task is arranged to have a single reversed discrimination occurring in a consistent location within each session and across sessions. In this task, we examine the relevance of time, reinforcement...
The present survey is a correlation study designed to determine extent and type of relation between mid-arm circumference and weight in order to offer a scale for assumption of weight. 390 healthy, adults who are resident in Tehran and between the ages 18-65 were selected from visitors at three hospital censers at random. Input accumulation was carried out by means of a questionnaire an...

Renewable energy sources, such as wind turbines, have become much more prevalent in recent years, and thus a popular form of generation. This is part due to the ‘Fit for 55’ EU initiative, part, rising fossil fuel prices, well perceived requirement nations power independence, influence renewable sources we can see marked increase large farms particular. However, by their very nature are highly ...
We present results of ultra-deep ISOCAM observations through a cluster-lens at 7μm and 15μm with the Infrared Space Observatory (ISO) satellite. These observations reveal a large number of luminous Mid-Infrared (MIR) sources. Crossidentification in the optical and Near-Infrared (NIR) wavebands shows that about half of the 7 μm sources are cluster galaxies. The other 7 μm and almost all 15 μm so...
در این پایان نامه به بررسی نامساوی های نیمه تغییراتی- تغییراتی با شرایط مرزی نیومن ناهمگن خواهیم پرداخت. فصل اول شامل تعاریف، مفاهیم و قضایای مقدماتی است و فصل دوم به بیان و بررسی قضیه نقاط بحرانی که در فصل های بعدی کاربرد زیادی دارد، اختصاص یافته است. در فصل سوم با استفاده از قضیه نقاط بحرانی، وجود دنباله ای بی کران از جواب های ضعیف، برای معادلات بیضوی شاملp - لاپلاس را بررسی خواهیم کرد. در فص...
نامساوی ها یکی از مهمترین حوزه های پژوهشی آنالیز ماتریسی هستند که از ابتدا مورد علاقه بسیاری از ریاضی دانان بوده و کاربردهایی در علوم مختلف از جمله محاسبات علمی، نظریه سیستم و کنترل، تحقیق در عملیات، فیزیک ریاضی، استاتیک، اقتصاد و مهندسی دارد. نخستین بار در سال $1934$ کتاب تقریبا جامعی با نام "نامساوی ها" cite{h} توسط هاردی، ltrfootnote{g. h. hardy} لیتل وود ltrfootnote{e. little...
Generation of broadband 17-μJ mid-infrared femtosecond pulses at 3.75 μm by silicon carbide crystal.
In this contribution, we report the generation of 17-μJ mid-infrared (MIR) pulses with duration of 70 fs and bandwidth of 550 nm centered at 3.75 μm at 1-kHz repetition rate, by a two-stage femtosecond optical parametric amplifier utilizing 4H-silicon carbide crystal as the nonlinear medium. The crystal is selected as it processes orders of magnitude higher damage threshold than traditional MIR...
