بسته نرم افزاری dssat که مخفف سیستم پشتیبان تصمیم گیری در انتقال تکنولوژی کشاورزی می باشد، بیش از 20 سال است که مورد استفاده محققان در سراسر جهان می باشد. مدل csm-ceres-maize یکی از مدل های موجود در بسته نرم افزاری dssat می باشد که برای شبیه سازی رشد و نمو ذرت توسعه داده شده است. برای انجام این تحقیق، از داده های مزرعه ای ذرت علوفه ای در دو سال زراعی (1382-1383) استفاده شد. اطلاعات مربوط به گیا...
the objective of this study was to evaluate the effect of cottonseed meal (csm) treated with sodium bentonite (sb) on laying hen profit and apparent digestibility of nutrients. a 3×3 factorial arrangement in a completely randomized design with 9 dietary treatments of 4 replicates consisting 3 levels of sb (0, 1 and 2%) and 3 levels of csm (0, 10 and 20%) were tested. nine mash diets were fed to...
با توجه به اینکه امروزه سازمان ها در محیط های مبهم، پیچیده و متلاطم مشغول به فعالیت هستند و به منظور پایداری و رشد در محیط خود به نظر می رسد که به ساختار با ویژگی هایی نیازمندند که به طور جامع بتواند تمامی فعالیت های سازمانی را پوشش داده و روندی را به سوی توسعه و پایداری داشته باشد. هدف از تحقیق حاضر معرفی ساختاری با ویژگی های سازمان های سیبرنتیک محور تحت عنوان csm (مدیریت کنکاش- سیبرنتیک) اس...
Cervical spondylotic myelopathy (CSM) is a common disorder involving chronic progressive compression of the cervical spinal cord due to degenerative disc disease, spondylosis, or other degenerative pathology. CSM is the most common form of spinal cord impairment and causes functional decline leading to reduced independence and quality of life. Despite a sound understanding of the disease proces...
The basis of the vasodepressor response in patients with carotid sinus hypersensitivity (CSH) is unknown, and prevention of recurrent vasodepressor-induced hypotension in these patients has not been possible. In this study we assessed the effectiveness of atrioventricular sequential pacing and pharmacologic interventions in the prevention of carotid sinus massage (CSM)-induced vasodepressor res...
a r t i c l e i n f o Keywords: Crop model CSM DSSAT Genetic algorithm Hyperspectral LAI Model inversion Nitrogen Optimization PEST PROSAIL Simulation Wheat Yield Remote sensing technology can rapidly provide spatial information on crop growth status, which ideally could be used to invert radiative transfer models or ecophysiological models for estimating a variety of crop biophysical propertie...
A functional study of purinergic signalling in the normal and pathological rabbit corpus cavernosum.
OBJECTIVE To examine rabbit cavernosal smooth muscle (CSM) relaxation to ATP, ADP and UTP in normal rabbits and in models of conditions that predispose to erectile dysfunction (ED), diabetes mellitus (DM; induced for 6 months) and bladder outlet obstruction (BOO, 6 weeks after surgery). MATERIALS AND METHODS Concentration-response curves (CRCs) were constructed to ATP, ADP and UTP on CSM from...
BACKGROUND Cervical spondylomyelopathy (CSM), also known as wobbler syndrome, affects mainly large and giant-breed dogs, causing compression of the cervical spinal cord and/or nerve roots. Structural and dynamic components seem to play a role in the development of CSM; however, pathogenesis is not yet fully understood. Physiologic and pathologic movements of the cervical spine depend on the mor...
STUDY DESIGN Review. OBJECTIVES Cervical spondylotic myelopathy (CSM) is a major cause of disability, particular in elderly patients. Awareness and understanding of CSM is imperative to facilitate early diagnosis and management. This review article addresses CSM with regard to its epidemiology, anatomical considerations, pathophysiology, clinical manifestations, imaging characteristics, treat...
