results mean age was 41.6 ± 9.2 for the military truck drivers and 43.4 ± 10.9 for commercial truck drivers (p > 0.05). no significant difference between military and commercial drivers was found in terms of driving experience, number of mvcs, binocular va, frequency of color vision defects and cs scores. in contrast, the last ocular examination was significantly earlier in military drivers tha...
Experimental evidence for a 5-exocyclic methylene-dUMP intermediate in the thymidylate synthase reaction was recently obtained by demonstrating that tryptophan 82 mutants of the Lactobacillus casei enzyme produced 5-(2-hydroxyethyl)thiomethyl-dUMP (HETM-dUMP) (Barret, J. E., Maltby, D. A., Santi, D. V., and Schultz, P. G. (1998) J. Am. Chem. Soc. 120, 449-450). The unusual product was proposed ...
Motivated by the field sta routing and scheduling problem of an Austrian infrastructure service provider, which involves the planning of subroutes, we study the truck and trailer routing problem (TTRP) [2]. In the TTRP, two types of customers are considered: customers that can be visited by a truck pulling a trailer (denoted as vehicle customers) and customers that can only be visited by a truc...
Initial commissioning of the LHC beam dump system with beam took place in August and September 2008. The preparation, setting-up and the tests performed are described together with results of the extractions of beam into the dump lines. Analysis of the first detailed aperture measurements of the extraction channels and kicker performance derived from dilution sweep shapes are presented. The per...
Sewage sludge dumped at Garroch Head in the Firth of Clyde contains significant quantities of chlorinated hydrocarbons, such as polychlorinated biphenyls (CBs). These compounds are lipophilic and resistant to degradation. They accumulate in the biota either from the water column or through the food chain, particularly in tissue with a high lipid content. Bottom dwelling fish, such as plaice, in...
This research aims to calculate the production capability of loading and conveyance equipment used in coal mining activities, find out what factors affect non-achievement suggestions, then make efforts increase so that targets have been set can be achieved. . In this study, observation retrieval data field directly (primary data) indirectly (secondary will carried processing. Based on results c...
During a period of 60 days assays were carried out with the moss Pohlia nutans transplanted from an uncontaminated control site to a dump consisting of a heavily polluted mine and smelter wastes located near wałbrzych in southwestern Poland. within the same period also samples of native P. nutans growing on the dump substrate were collected together with the same species from a control site. Co...
The object of research is the process unloading bulk crop products from bodies dump trucks, subject study dependence energy consumption on properties when exposed to vibration. This understood as a change in products, such internal friction and angle repose, direction decreasing, providing decrease lift body. One most problematic areas lack objective information required lifting angles truck bo...
