Recent progress regarding the development of artificial site-selective DNA cutters by chemical approaches are reviewed herein, with a special focus on site-selective cutters for single-stranded DNA. We employ a Ce(IV)/EDTA complex to serve as the catalyst, because it efficiently and selectively cuts single-stranded DNA. Using two complementary oligonucleotide additives, a gap structure is forme...

Up to now, the BAUER Trench Cutter Cut-Off Wall (COW) technology has been developed for more than 20 years for use on large dams. The special task of a COW is to mitigate seepage and therefore COW's are utilized either on dam rehabilitation projects or on new dams as well. Seepage mitigation, for the long-term stability and the safety of dykes and dams, is a major issue to the designers. Cut-of...

The South African sugar industry harvests in excess of 20 million tons of sugarcane annually. More than 90% of this tonnage is currently being harvested manually. During 2002, the South African Sugar Association Experiment Station’s Agricultural Engineering Department conducted a comprehensive cane cutter survey throughout the South African and Swaziland sugar industries. The primary objective ...

In Tanzania, the effect of sugar cane chewing on the development of caries was investigated. Two groups were selected; those who had easy access to sugar cane (sugar cane cutters) and those who did not (sisal plant workers). These groups had a similar socio-economic background, had similar levels of fluoride in drinking water, consumed similar amounts of refined sugar per day, but had a signifi...

Recent progress in the study of antigen-antibody reactions of biologicals in agar gel demands improvement of existing gel-cutting devices. For an ideal comparison of two or more antigenic preparations against an antiserum, it is necessary to obtain a critical distance between the ( antigen and antibody cups and to obtain a partial or complete identity of precipitinogen in adjacent cups. However...

In this paper an uncapacitated multiple allocation p-hub median problem is discussed. The model minimizes the transportation cost based on inventory service level at hubs through double paths between hubs. Inventory service level is defined as the percent of inventory shortage of vehicles at hubs according to passengers demand and replenishment time of vehicles. A real data from 25 nodes of mun...

The big sized milling cutters are expensive tools and not appropriate for small batches production. Making these more versatile, able to fit different kinds of processes shapes the parts be machined is a must. As well, cooling cutting area very important. existing end-mill designed feed internally with coolant only teeth on front side. paper presents concept modular tool, made elementary disk c...
