this study presents a detailed analysis of cost management for intensive cultivation activity in terms of tomato production. the main objective was to provide qualitative and quantitative costs obtained in the intensive cultivation of tomato. this methodology was structured by activity costs (soil preparation and planting, crop monitoring, harvesting, selling, etc.) through a study in greenhous...

in order to study the trend of bnyvv concentrations during growing season, 6 cultivars including dorohtea, laetitia(as resistant cultivars), zarghan (as a tolerant cultivar), shirin (as a susceptible cultivar), f2-93 (an f2 population with 75 % rz2 gene) and bc1-261-99 (a population with 25% rz2 gene) were used. the cultivars were planted in split plot based on a randomized complete block desig...

Methodological dualism in linguistics occurs when its theories are subjected to standards that are inappropriate for them qua scientifi c theories. Despite much opposition, methodological dualism abounds in contemporary thinking. In this paper, I treat linguistics as a scientifi c activity and explore some instances of dualism. By extracting some ubiquitous aspects of scientifi c methodology fr...

Technical aspects of composite arterial grafting with double skeleton-ized internal thoracic arteries. Bilateral skeleton-ised internal thoracic artery graftings in off-pump coronary artery bypass: early result of Y versus in situ grafts. results of coronary grafting using ultrasonically skeletonized internal thoracic arteries. We read with great interest the recent review from Dr. Ali and cowo...

Four field experiments were conducted to study the effect of Sesbania rostrata and Aeschynomene afraspera as rotational and green manure crops on the population dynamics of Hirschmanniella mucronata and H. oryzae, and subsequent rice yields. The sequential cropping of the legumes with rice controlled both nematode species. In two experiments, yield of rice was related to the nematode population...

Operating heavy equipment can be a difficult and very tedious task. Control of an agricultural tractor requires the continuous attention of the driver, and farmers often work long hours during critical times of planting and harvesting. Loaders and other ground vehicles are frequently used in situations that are unpleasant or even hazardous for a human operator. This paper explores the use of ca...
