Background : Leptospirosis is a growing public health concern in many tropical and subtropical countries. However, its diagnosis is difficult because of non-specific symptoms and concurrent other endemic febrile diseases. In many regions, the laboratory diagnosis is not available due to a lack of preparedness and simple diagnostic assay or difficult access to reference laboratories. Yet, an ear...

BACKGROUND Malaria presents a diagnostic challenge in most tropical countries. Rapid detection of the malaria parasite and early treatment of infection still remain the most important goals of disease management. Therefore, performance characteristics of the new indigenous ParaHIT f test (Span diagnostic Ltd, Surat, India) was determined among ethnic tribal population in four districts of diffe...

Lateral flow immunochromatographic rapid diagnostic tests (RDTs) are the primary form of medical diagnostic used for malaria in underdeveloped nations. Unfortunately, many of these tests do not detect asymptomatic malaria carriers. In order for eradication of the disease to be achieved, this problem must be solved. In this study, we demonstrate enhancement in the performance of six RDT brands w...

Considering a checkpoint and communication pattern, the Rollback Dependency Track-ability (RDT) property stipulates that there is no hidden dependency between local checkpoints. In other words, if there is a dependency between two checkpoints due to a non-causal sequence of messages , then there must exist a causal sequence of messages that \doubles" the non-causal one and that establishes the ...

Neutral proteinases of neutrophilic polymorphonuclear leukocytes were followed up cytochemically in blood smears of 12 patients submitted to regular hemodialysis treatment (RDT). Halo formation (ring-shaped area around each neutrophil due to protein degradation) was reduced in all patients with end-stage renal disease under RDT. Concomitant to the development of leukopenia, a maximal increase o...

Malaria rapid diagnostic tests (RDTs) are known to yield false-positive results, and their use in epidemiologic surveys will overestimate infection prevalence and potentially hinder efficient targeting of interventions. To examine the consequences of using RDTs in school surveys, we compared three RDT brands used during a nationwide school survey in Kenya with expert microscopy and investigated...

INTRODUCTION Delay in appropriate treatment in patients with bacteraemia can increase morbidity, mortality, and health expenditures. We compared the Rapid Direct Test (RDT) designed to detect ESBL-producing gram-negative bacteria (GNB) directly from positive blood cultures bottles, with two conventional ESBL detection tests: Screening and Confirmatory Disk Diffusion Assay (SC-DDA) and an MIC Sc...

Thirty years have passed since Pfeffer and Salancik’s seminal work on resource dependence theory (RDT). During this time RDT has been applied broadly across the research domain to explain how organizations reduce environmental interdependence and uncertainty. In this review, the authors assess the conceptual development, empirical research, and application of RDT. They structure their review ar...

ÐRecursive Diagonal Torus (RDT), a class of interconnection network is proposed for massively parallel computers with up to 2 nodes. By making the best use of a recursively structured diagonal mesh (torus) connection, the RDT has a smaller diameter (e.g., it is 11 for 2 nodes) with a smaller number of links per node (i.e., 8 links per node) than those of the hypercube. A simple routing algorith...

Conducting a Reliability Demonstration Test (RDT) is a crucial step in production. Products are tested under certain schemes to demonstrate whether their reliability indices reach pre-specified thresholds. Test schemes for RDT have been studied in different situations, e.g., lifetime testing, degradation testing and accelerated testing. Systems designed with several structures are also investig...
