Metabolome Analysis of Drosophila melanogaster during

Aug 14, 2014The Drosophila melanogaster embryo has been widely utilized as a model for genetics and developmental biology due to its small size, short generation time, and large brood size. Information on embryonic metabolism during developmental progression is important for further understanding the mechanisms of Drosophila embryogenesis. Therefore, the aim of this study is to assess the changes

7 Hazards That Make Confined Spaces Dangerous Places

Dec 21, 2018During construction work, some areas may become confined spaces due to the work being carried out, for example within trenches, unventilated rooms or building voids.

corner radius Archives

Nov 22, 2019The most common profile styles for end mills are square, corner radius, and ball. The square profile on an end mill has flutes with sharp corners that are squared off at 90. A corner radius profile replaces the fragile sharp corner with a radius, adding strength and helping to prevent chipping while prolonging tool life.

MECHANICAL ALLOYING AND MILLING

Different types of high-energy milling equipment are used to produce mechanically alloyed/milled powder.

Planetary ball milling is a possible way to improve the technological properties of wheat by thermal and mechanical modifications. In the present study, roller milled common wheat flours (Triticum aestivum L.) were additionally modified in a ball mill by varying mill parameters such as

Energy efficiency • Energy intensity in copper and gold

Mines are faced with numerous challenges, such as falling raw material prices, declining metal grades in the ores and higher energy prices. Especially because ore processing is particularly energy-intensive, the industry is again focusing on the saving of energy. This report shows what are the key energy saving considerations in the copper and gold mining sectors.

Improved Productivity in Mining. SafeSet Torque

Too much material or uncrushables in the mill might cause a rapid increase in torque or a total blockage of the machine. Ball Mill, Sag Mill, AG Mill, Roller Press HPGR, HRC Tunnelling Hard rock layers, or too high drilling speed cause torque peaks. This can also occur during commissioning.
