این مطالعه با هدف محاسبه مقدار دبی پیک سیلاب و شناخت عوامل موثر بر سیلخیزی حوضه رازآور استان کرمانشاه با استفاده از روش scs انجام شده است. برای محاسبه دبی پیک سیلاب، ابتدا حوضه به زیرحوضههایی با رتبه آبراههای 5، 6 و 7 تقسیم شده و سپس فاکتورهای موثر بر سیلخیزی حوضه مانند مساحت، شماره منحنی cn، زمان تأخیر، زمان تمرکز، شدت بارش، کاربری اراضی، شیب، زمینشناسی و پوشش گیاهی مطالعه، و دبی پیک سیل...
مهمترین هدف در واسنجی مدل های مفهومی بارندگی-رواناب (crr) پیدا کردن مقادیر بهینه برای مدل می باشد که با استفاده از آن بتوان بهترین منحنی را برای هیدروگراف های مشاهده شده و محاسبه شده برازش داد. با وجود عمومیت این مدل ها، در صورتی که نتوان یک مقدار بهینه منحصر به فرد برای پارامترهای آن با استفاده از واسنجی خودکار به دست آورد، کاربرد آن مدل ها بسیار مشکل خواهد بود. همچنین استفاده از هیدروگراف ها...
Chronic neuropathic pain caused by injury to or disease in the nervous system is relatively common and results in major suffering, poor quality of life and incapacity. Such pain is a therapeutic challenge because a considerable portion of the patients fails to benefit from pharmacotherapy. Therefore, there is a need for alternative treatment modalities. Spinal cord stimulation (SCS) has proven ...
provided the original work is properly cited. CC A spinal cord stimulator is usually used as an electro-modulator for pain treatment. Shealy et al. [1] first reported the use of a spinal cord stimulator in an elderly male suffering with terminal bronchogenic carcinoma and right-sided chest pain in 1967. Since then, spinal cord stimulation (SCS) has been applied to many disease entities, such as...
BACKGROUND A stepped care strategy (SCS) to improve adequate healthcare use in patients with osteoarthritis was developed and implemented in a primary care region in the Netherlands. AIM To assess the association between care that is in line with the SCS recommendations and health outcomes. DESIGN AND SETTING Data were used from a 2-year observational study of 313 patients who had consulted...
Self-compassion is increasingly explored as a protective factor in relation to psychopathology. The Self-Compassion Scale (SCS) and its Short Form variant (SCS-SF) are the most widely used instruments for measuring this psychological construct, and previous studies have indeed shown that the total score of this scale is negatively associated with psychopathology. In this article, we point out t...
objective: transplantation of bone marrow stromal cells (bmscs) or schwann cells (scs) can facilitate axonal regeneration in peripheral nerve injuries. the aim of this study was to compare the effects of transplantation of bmscs and scs on functional recovery after injury to the sciatic nerve in the rat. materials and methods:in this experimental research, adult male wistar rats (n=24, 250-300 ...
Soils support ecosystem functions such as plant growth and water quality because of certain physical, chemical, and biological properties. These properties have been studied at different spatial scales, including point scales to satisfy basic research needs, and regional scales to satisfy monitoring needs. Recently, soil property data for the entire USA have become available in the State Soil G...
The purpose of this study was to assess the validity and reliability of the Sense of Contribution Scale (SCS), a newly developed, 7-item questionnaire used to measure sense of contribution in the workplace. Workers at 272 organizations answered questionnaires that included the SCS. Because of non-participation or missing data, the number of subjects included in the analyses for internal consist...
