AIMS To determine the minimum number of calibrant plasmas required to assign an accurate System International Sensitivity Index (ISI). METHODS Eighteen lyophilised adsorbed and eight frozen coumarin plasmas were despatched to 57 participating laboratories. Each centre determined the prothrombin time of all of the plasmas using their routine system of coagulometer and thromboplastin reagent an...

While it is generally accepted that water hardness affects copper toxicity, the major ions that contribute to water hardness (calcium [Ca] and magnesium [Mg]) may affect copper toxicity differently. This is important because the Ca:Mg ratio in standard laboratory-reconstituted waters often differs from the ratio in natural surface waters. Copper toxicity was assessed for five different aquatic ...

BACKGROUND Control of brucellosis in livestock, wildlife and humans depends on the reliability of the methods used for detection and identification of bacteria. In the present study, we describe the evaluation of the recently established real-time PCR assay based on the Brucella-specific insertion sequence IS711 with blood samples from 199 wild boars (first group of animals) and tissue samples ...

The indirect enzyme-linked immunosorbent assay (IELISA), the competitive enzyme-linked immunosorbent assay (CELISA) and the fluorescence polarisation assay (FPA) were evaluated with sera from sheep experimentally infected with Brucella melitensis and negative Canadian sheep. The sensitivity and specificity of the assays were as follows: IELISA: 91.7% and 97.6%, CELISA: 75.0% and 99.8% and FPA: ...

background brucellosis remains a major worldwide zoonosis. caprine brucellosis is a significant problem for both public health and animal production. brucella melitensis causes disease in goats, sheep, humans, and occasionally cattle. transmission is by ingestion or contact with infected materials, vaginal discharge, or milk. objectives the current study aimed to determine the rate of b. melite...

Rehabilitation technologies are rapidly evolving, presenting promising interventions for people with neurological impairments. Access to technology, however, is greater in metropolitan than rural areas. Applying a capabilities approach this access issue foregrounds healthcare recipients’ rights and personhood within the discourse on resource allocation. Within context, study aimed investigate e...

Green innovation has become one of the mainstream concepts to address environmental issues. However, research on green innovation, especially at firm level, is still evolving. Building upon natural resource-based view (NRBV) and theory (RBT) lenses, this study proposes a framework explore determining factors adoption (GIA) in Brazilian cassava agribusiness sector. The design from semi-structure...

Methods. Various laboratory tests were implemented in our lab, as screening or confirmatory tests, some in studies some as a routine diagnostic test, such are: Agglutinations tests: Rose Bengal test (RBT), Slide Agglutinations test, Standard tube test (SAT), Wright test, Antihuman globulin test (Coombs); 2-Mercaptoethanol test (2 ME); Complement fixation test (CFT); Indirect enzyme immunoassay ...

The Mobile Industry, which is one of the most dynamic and growing industry in the world, is no longer just about the delivery of voice over phones. Introduction of new content services such as logo-melody or RBT (Ring Back Tone), and voting-contest services, data services, messaging services and java games make it more dynamic. The future of mobile telephony is expected to rely on mobile servic...

Fatigue information has been reliable in predicting wire critical structural integrity. The aim of this study is to expound on the characterization technique of rotary beam fatigue testing RBT . By alternating tension and compression stress states through RBT, it is possible to determine the life expectancy of Nitinol monofilament round wires. Fatigue testing has been employed to characterize t...
