mechanical weeding is one of the non-chemical methods to control weeds. in this paper a ‎new mechanism has been presented for mechanical cultivation. the machine works based on ‎the manual tools operation, which farmers still use in small scale for weeding and consists of a ‎number of four-bar linkage mechanisms. each mechanism consists of a blade which moves ‎forward (active course) and backwa...

Agricultural Training Centres (ATCs) promote crop and livestock development by providing extension information to farmers and serving as models of improved crop and livestock husbandry practices. Although potato farmers in Nyandarua County were trained on potato production technologies, their average yield was ≤16 tonnes per hectare compared to the national potential of 30 tonnes. This study th...

The study was conducted with a sample of 120 sericulture farmers in Kamrup district Assam three development blocks viz. Bongaon, Boko and Chayani Borduwa. revealed that majority (43.33%) the respondents belonged to middle age group, 36.67% were illiterate, 45.83% small size family 69.17% had pucca house. In case operational land holding (34.17%) possessed holding, 33.95% annual income ranging f...

In this paper, the mechanism of improvement of formability in pulsating hydroforming of T-shape tubes is investigated by the finite element simulation and experiment. It is shown that local thinning was prevented by oscillating the internal pressure, because the protrusion is formed gradually by the prevention of sharp bulging. In the hydroforming, for the pulsating pressure, several steps occu...

Local newspapers are an important source of health news, especially in small communities. We describe the amount and type of cancer information in Ontario daily newspapers dichotomized by circulation size (> 400,000 or < 40,000) and community size (> 250,000 or < 25,000 people) for 1991. All cancer articles (n = 1027) in five newspapers with large circulations, serving large communities, and fi...

Punjab is the state that contributes most food grains to central pool and mostly an agricultural state. Small marginal farmers are backbone of Indian agriculture. Majority holdings medium number such increasing with fragmentation land. So, present study was conducted objective studying socio-economic characteristics respondents. Data were collected from Pathankot Gurdaspur district Punjab. Two ...

This paper reports the result of an analytical investigation of a steady, incompressible and viscous flow between two eccentric, rotating cylinders at high Reynolds number. A one dimensional case is far from reality because the gap between the cylinders is very small. Further, when their axes are displaced by a small distance, usually caused by bearing loads, two dimensional effects become obvi...
