By using analytical correlations derived as a result of theoretical research, a computer algorithm has been worked out for simulating the functions of the plough body and the forces exerted by soil upon the operating parts, as well as its draft resistance. These correlations allow to determine the draft resistance of the plough depending on the parameters of its body, as well as to evaluate the...

On the Origins of Gender Roles: Women and the Plough This paper seeks to better understand the historical origins of current differences in norms and beliefs about the appropriate role of women in society.

A three-year field study was conducted evaluate corn (Zea mays L) productivity four ranging intensity soil disturbance (i.e. Moldboard-CT, Chisel-CT, ST, NT) a furrow-irrig...

Drilling-induced delamination often occurs both at the entrance and the exit of the workpiece during drilling of composite material. Investigators have studied analytically and experimentally that delamination in drilling can be correlated to the thrust force of the drill. With a pre-drilled pilot hole, the delamination can be reduced significantly. Early reference reported models of drilling-i...
