Proper selection of energy-efficient agricultural machinery helps to reduce drudgery, increase cropping intensity and time required for field preparation. With conventional tillage implements, multiple passes are obtain desired seedbed which soil compaction due repeated movement tractor in field. combined implements two or more fuel energy In this paper, various researches on active-passive pas...

celecoxib is used in the treatment of osteoarthritis, rheumatoid arthritis, acute pain, joint inflammation and sport injuries. long term administration of the drug results in such complications as gastrointestinaland renal disturbances and cardio-vascular complications. the main objective of the present study was to investigate the feasibility of delivering celecoxib incorporated in gel formula...

introduction: estrogen is one of the gonadal hormones that has multiple beneficial actions in central nervous system and involves in learning and memory. alzheimer's disease (ad) is a progressive neurodegenerative disorder that impairs patient memory. the human nucleus basalis of meynert (nbm) is severely affected in alzheimer's disease. so in this study the effect of peripheral (intr...

background: this study aimed to survey a total five common human and veterinary antibiotics, including ampicillin, oxytetracycline, enrofloxacin, tylosin, and ciprofloxacin based on spe-lc-ms-ms technology in a wastewater treatment plant at central plateau of iran. also two sampling techniques, passive and grab samplings were compared in the detection of selected antibiotics. methods: in februa...

A method is proposed for determining the motion of a body relative to a fixed environment using the changing image seen by a camera attached to the body. The optical flow in the image plane is the input, while the instantaneous rotation and translation of the body are the output. If optical flow could be determined precisely, it would only have to be known at a few places to compute the paramet...

Different materials reflect light in different ways, so reflectance is a useful surface descriptor. Existing systems for measuring reflectance are cumbersome, however, and although the process can be streamlined using cameras, projectors and clever catadioptrics, it generally requires complex infrastructure. In this paper we propose a simpler method for inferring reflectance from images, one th...
