OBJECTIVES To perform a meta-analysis of prospective, randomized controlled trials comparing the closed and open technique of diagnostic peritoneal lavage (DPL) in trauma patients to determine whether there are any difference in outcomes. METHODS A search of MEDLINE database of English language articles published from 1977 to 1999 was conducted by using the terms diagnostic peritoneal lavage,...

Diagnostic peritoneal lavage (DPL) is a highly accurate test for evaluating intraperitoneal hemorrhage or a ruptured hollow viscus, but is performed less frequently today due to the increased use of focused abdominal sonography for trauma (FAST) and helical computed tomography (CT). All three of these exams have advantages and disadvantages and thus each still play unique roles in the evaluatio...

Several proteins linked to neurodegenerative diseases, such as the beta-amyloid precursor protein, amyloid beta-peptide, beta-secretase, and tau, undergo selective polarized sorting. We investigated polarized sorting of the mammalian prion protein (PrP(C)) and its homologue doppel (Dpl). In contrast to Dpl, which accumulates on the apical surface, PrP(C) is targeted selectively to the basolater...

Educators have witnessed lately a proliferation of Web-based learning applications. These Web-learning environments have made learning much more convenient by stretching the spatial and temporal barriers. Their effectiveness, however, remains to be examined. In this research, the authors study the relative effectiveness of two different types of Web-learning environments: distributed passive le...

constituent-pairs (ie. words or recognized phrase constructs) and (3) description of constituent surroundings in the form of two-way automata. The compilation of DPL-grammars results in e>;ecutable codes of corresponding parsers. To ease the modelling of grammars there exists a linguistically oriented programming environment, which contains e.g. tracing facility for the parsing process, grammar...

In the theory of computation a new viewpoint is digging in: to compute is to pin down the constraints that hold in a given problem domain, and a goal for computation. It is up to an interpreter to perform search for the goal in the problem domain. The result of computation follows then indirectly from the search process. Strongly pronounced and in wide use this vantage point becomes in Prolog. ...

Heterosis over better parent for seed yield and its component traits were studied in 28 crosses derived from a diallel mating involving 8 diverse parents of lentil. For seed yield heterosis ranged from -1.73 to 48.35 (%). Twenty two crosses had positive and significant heterosis for seed yield, out of them 9 crosses viz., DPL 62 x K 75, PL 4 x K 75, B 18 x Lens 830, PL 4 x B 18, B 18 x K 75, PL...

In this paper, we investigate the deficiency of uncontrolled asymmetrical transmission power over multiple channels in ad hoc environments. We further propose a novel distributed transmission power control protocol called the distributed power level (DPL) protocol for multi-channel ad hoc networks without requiring clock synchronization. Specifically, different transmission power levels are ass...

D The best-known algorithm for the satisfiability problem in the case of propositional formulae (SAT) is the implicit enumeration version of the Davis-Putnam algorithm, as described in Loveland's book . We review this algorithm, which we call DPL, and some recent variants . As it is often the case with enumerative algorithms for decision type problems, neither DPL nor its variants incorporate a...

The 1995 EU Directive on data protection legislation (DPL) ensures free flow of data within the EU. However, the transfer to countries without adequate DPL is generally forbidden. The effect of this Directive on the business of MNCs is still unknown but a few authors foresee major problems for MNCs doing business in Europe. On the eve of the implementation of the new EU data protection directiv...
