Method comparison studies of two different methods for the analysis of weak acid dissociable (WAD) cyanide revealed analytical flaws and/or matrix interference problems with both procedures. EPA "draft" method 1677 using a Perstorp 3202 CN analyzer was compared to Standard Method 4500 CN I. It was discovered that the Perstorp analyzer produced more precise and more accurate results once appropr...

background: the performance and parasitology of semi-intensively managed west african dwarf (wad) lambs were evaluated following exposure to gastrointestinal helminth infected paddock and varied protein-energy feeds. methods: twenty four lambs obtained from the department of animal breeding and genetics and brought to directorate of university farm (dufarm) of federal university of agriculture ...

Energy and protein utilization quantitative retention of protein, fat energy was investigated with twelve castrated West African Dwarf (WAD) sheep averaging (23.0 h 2.4 kg BW) in nitrogen balance trials. Dried leaves Leucaena leucocephala were offered as supplement at two levels 25% (diet 2) 50% 3) dry matter intake (DM1), replacing hay the basal diet. The diet without supplementation control. ...

The paper investigates the interaction effects between the search strategy of software agents and the subject’s product class knowledge. The experimental study consists of a 2 (product class knowledge: high, low) x 4 (agent search strategy: elimination by aspects (EBA), weighted average method (WAD), profile building (PROFILE) , and simple hypertext (HYPERTEXT)) design with product class knowle...

The aim of this systematic review was to determine the effectiveness of acupuncture for the treatment of whiplash associated disorder (WAD). Twenty databases were searched from their inceptions to Oct. 2013. Randomised clinical trials (RCTs) of acupuncture (AT), electroacupuncture (EA), or dry needling (DN) for the treatment of WAD were considered eligible. The risk of bias was assessed using t...

Whiplash injuries resulting from rear impacts are one of the most important injury categories with regard to long-term consequences. Most rear impacts lead to no injury or to symptoms that are temporary. Impacts where the duration of symptoms differs need to be separated in analyses in order to isolate representative rear impact conditions in which more long-lasting whiplash injuries occur. The...

Hyalomma anatolicum anatolicum nymphs were collected from two localities in the Sudan: Eddamer in Northern Sudan and Wad-Medani in Central Sudan. They were allowed to moult to adult ticks, which were assessed for Theileria infection in their salivary glands using Feulgen stain. At Eddamer, 49.6% of 123 ticks examined were infected with Theileria and the mean intensity of infection was 1.3 (i.e....

nutritive value of rumen epithelial scraping (rep) was assessed using in sacco and in vivo procedures. concentrates were so formulated that 0% (a), 35% (b), 70% (c), and 100% (d) of soybean meal (sbm), were replaced (weight for weight) with rep. in a completely randomized design, 16 west african dwarf (wad) goats were randomly allocated to the experimental diets to assess feed intake and digest...
