Traction resistance of the combined machine plough

Simulation of the Impact of the Soil Friction on the Draft Resistance of the Plough Body

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...

An evaluation of extraoral combined high-pull traction and cervical traction to the maxilla.

The effects of extraoral combined high-pull traction and cervical traction of known duration (mean, 122 days) and magnitude (2.5 to 3 pounds total per side) were studied by means of serial lateral cephalometric head films of thirty patients. The lateral cephalometric head films used were taken at three different times: before the extraoral force was applied, after the prescribed period of conti...

Dr. Harold Kleinert and the Plough

Kentucky, at his clinic which was a veritable beehive of activity almost entirely devoted to the surgery of the hand. I remember that it was located near about the Mohammad Ali Avenue, who recently passed away because that is where he was born as Casius Clay. Years before I first met Dr. Kleinert, I had served as a resident at the Grace Hospital in Detroit (1972) where they used to speak about ...

A comparison of the performance of a high speed disk plough and a general purpose mouldboard plough

Effects of Combined Training on the Levels of Obestatin, Ghrelin, and Insulin Resistance in Overweight Women

Background: The present quasi-experimental and field research was conducted to evaluate the effect of combined exercises on the levels of obestatin and ghrelin in overweight women. Methods: The study subjects consisted of 34 overweight women with a Mean±SD age of 30.29±4.66 years, a Mean±SD height of 165.11±5.56 cm, a Mean±SD weight of 74.64±7.33 kg, a Mean±SD body mass index of 27.35±1.74 kg/...
