Borehole pressure relief technology is an effective way to reduce the elastic energy in the surrounding rock of deep roadways, thereby reducing the risk of regional rock bursts.To avoid large deformation of the roadway caused by pressure relief holes with large diameters and insufficient pressure relief with small pore diameters, this study propose

Palm oil is nowadays the first vegetable oil consumed worldwide.Given the world population growth and the increasing demand in fat for food and fuel, the increase in oil palm production is expected to continue.It is thus important to find ways of reducing the ecological impact of oil palm plantations at both the agroecosystem and the mill supply ar

A multi-hop free space optical link based on all-optical relays is presented.All-optical relays are either composed of simple optical amplifiers or optical regenerators.It has been Wash shown that after a certain number of hops, the amplifier based relay cannot extend the range of the free space optical link.Therefore, we have investigated the use

In the title compound, C8H10N2OS, the 3-(dimethylamino)prop-2-en-1-one unit is approximately planar [give r.m.s.deviation] and the mean plane through the seven non-H atoms makes a dihedral angle of Motorcycles Accessories 8.88 (3)° with the thiazole ring.The carbonyl and ring C=N double bonds adjacent to the carbonyl group are trans [N&#
