introduction intercropping as a common method in sustainable agricultural systems, plays an important role in increasing productivity and yield stability to improve utilization of resources )alizadeh et al., 2010). studies in different countries showed that intercropping causes increase in diversity, production and more efficient use of water resources, land, labor and nutrients and also reduce...
ABSTRACT- A real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. The image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. The image frames were processed by LabView® and MatLab®. The developed algorithm, based on weed coverage ratio and seg...
In this study, the effects of different parameters on charpy impact properties of pure and hybrid composite laminates reinforced with basalt and glass filaments were investigated. For this purpose, five types of basalt and glass laminates with quasi-isotropic stacking sequence, namely, a pure basalt, a pure glass, two inter-ply hybrid and one intra-ply hybrid composites were produced...
Although different modifications of ridge tillage (RT) systems exist in regions around the world, positive impacts RT on crop yields and weed management are quite similar. This review gives a comprehensive summary forms highlights benefits for growth, mainly due to better access soil moisture, nutrients light. In temperate areas, can accelerate emergence because temperature is usually higher ri...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
Objectives: The Micro Manual Muscle Tester (MMMT) is a Hand-Held Dynamometer (HHD). The current study aimed to evaluate the intra- and inter-rater reliability of this device. Methods: To determine the reliability of the MMMT, two previously trained assessors to work with HHD performed HHD measurements on 7 muscle groups of the lower extremities (hip flexors, hip extensors, hip abductors, knee ...
Objectives: Knowledge about gender differences in intra-limb coordination during walking provides insight into the adaptability of central nervous system for controlling gait in older adults. We assessed the variability and phase dynamic of the intra-limb coordination in older men and women during walking. Methods: Twenty two older people, 11 female and 11 male, participated in this study. T...
دستگاه ها و تجهیزات موجود در صنایع داروسازی، ممکن است برای تولید محصولات دارویی متعددی به کار گرفته شوند، در نتیجه این امکان وجود دارد که فرآورده ها و مواد موثره دارویی توسط دیگر فرآورده ها یا مواد موثره، مواد شوینده، میکروارگانیسم ها و یا دیگر مواد، آلوده شوند، پس ما باید بتوانیم از آلودگی های احتمالی فرآورده جلوگیری نماییم. از این رو استفاده از فرآیند های شستشو اهمیت پیدا می کند و این فرآیند...
کارخانجات داروسازی در ایران، با توجه به محدودیت خطوط تولید و تنوع محصولات خود، ناگزیر به تولید چند محصول مختلف در یک خط تولید میباشند؛ در نتیجه در بسیاری از موارد، تجهیزات ودستگاههای یکسان برای تولید محصولات دارویی مختلف به کار گرفته میشوند؛ لذا فراورده ها و مواد موثره دارویی ممکن است توسط مواد موثره و مواد جانبی دیگر فراورده ها آلوده گردند؛ برای جلوگیری از این امر، هنگام تعویض محصول در یک خط ن...
