هدف: کارآفرینی یکی از عوامل کلیدی در توسعه اقتصادی و شاخص اساسی جوامع روبه‌رشد است. آنچه که کارآفرین را به آغاز فعالیت ترغیب می‌کند، انگیزه فرایند تبدیل یک فرد عادی است می‌تواند فرصت‌هایی ایجاد کند حداکثر رساندن ثروت کمک کند. هدف این پژوهش شناسایی طبقه‌بندی انگیزه‌های کارآفرینان می­باشد.طراحی/ روش‌شناسی/ رویکرد: با رویکرد مرور نظام­مند استفاده ماتریس شش سلولی دو مؤلفه جهت (کشش یا فشار) منبع (اق...

On-road exhaust emissions from light-duty vehicles are greatly influenced by driving conditions. In this study, two passenger cars (LDPCs) and three diesel trucks (LDDTs) were tested to investigate the on-road emission factors (EFs) with a portable measurement system. Emission characteristics of carbon monoxide (CO), hydrocarbons (HC) nitrogen oxides (NOx) emitted at different speeds, accelerat...

Introduction: Because of importance of impact of the Source to Surface Distance (SSD) in determining of monitor unit for electron-therapy, it is essential to know the Virtual Source Position (VSP) for electron beam for a linear therapeutic accelerator for each energy and field size. , especially using the Khan method (photo distance squared method) And compare the results with...

Until recently, storage protein research has been largely restricted to the seed-specific reserve proteins, which provide nutrients to seedlings during their early growth. Their abundance, and the potential for improving seed nutritional quality, were early incentives to investigate seed storage proteins, and they continue to be intensively studied as a plant model for tissue-specific and devel...

Seismic attenuation was estimated from compressional (P) and shear (S) waves carefully extracted three-component vertical seismic profiling (VSP) data. A high sensitivity of to fluid content noticed, which shows the advantage its use as a attribute for reservoir studies. Contrary most observations in fully saturated sandstones, magnitude P S wave studied carbonate zones is higher than one. This...

Let G = (V;E) be a graph. The travel times w(u; v) and w(v; u) are associated with each edge fu; vg 2 E, and a job, which is also denoted as v, is located at each node v 2 V . Each job v has release time r(v) and handling time h(v). A start node s 2 V and a set Q V of goal nodes are speci ed. The VSP (Vehicle Scheduling Problem) asks to nd a routing schedule of the single vehicle that starts fr...

BACKGROUND Health-related quality of life (HRQoL) assessment, encompassing the adolescents' perceptions of their mental, physical, and social health and well-being is increasingly considered an important outcome to be used to identify population health needs and to provide targeted medical care. Although validated instruments are essential for accurately assessing HRQoL outcomes, there are few ...

Individuals with developmental dyslexia usually exhibit a problem in simultaneous processing of multiple visual elements. However, the relationship between impaired (VSP) and reading difficulty is still debated. These inconsistencies may be associated wide range participants’ age, variation orthographic depth background languages, complex subcomponents underlying VSP. The present study thus exa...
