Tilemsi rock phosphate (TRP) of Mali is one of the most promising rock phosphate in West Africa for soil fertilization, but it is little used because of its insoluble form. The main objective of this study is to investigate TRP effects on rhizobia associated with the multipurpose leguminous tree Sesbania sesban grown on a sandy soil, poor in phosphorus and not sterilised. The experiment include...

A previously undescribed anaphylactoid reaction to haemodialysis, haemofiltration, or membrane plasma separation occurred in 15 patients receiving regular dialysis. The illness varied in severity from urticaria, sneezing, and watering of the eyes to severe bronchospasm and cardiovascular collapse, and began within a minute of blood being returned from the dialyser or filtration device to the pa...

5-HMF was discovered and first synthesised from inulin over a century ago (G. Dull, Chemiker Zeitung, 1895, 216). The substance was first identified in food in the 1950s. It is generated in the process of heating food containing sugar or carbohydrates, the result of a reaction from reducing hexoses in the presence of amino acids or proteins, as described by Maillard in 1912. 5-HMF levels can be...

Ring-forming species of spinifex grasses (Triodia spp.) are a dominant feature across much Australia’s arid and semi-arid zone. Researchers have long been curious about the mechanisms underpinning their striking growth form. However, none factors investigated to date provide convincing explanation for ring formation. Here, we asked whether an accumulation pathogenic soil microbes might impede s...

This study set out to test the hypotheses that: 1) stock sterilised in a central sterilizing supply department using the guidelines from the Australian Standards (AS4187) will not become contaminated over two years unless it is exposed to an event; and, 2) a variety of packaging types can be used successfully in maintaining a sterile barrier over the two year trial period. A random controlled, ...

Building roofs represents a critical pathway for sediment mixing with rainwater. This study aims to explore the correlation between roof-top deposited matter in different areas of Ikorodu Local Government Area Lagos, Nigeria. The deposition rate on roof was studied 34 weeks total (i.e., 17 weekly analyses rainy season and dry season). collected by 10 inch funnel directed into 5 L container, whi...

Herbicide degradation is one of the key processes determining whether use herbicide will have any impact on environmental quality, and it dependent various biotic abiotic factors. The present study evaluates factors such as soil type, application rate, incubation temperature, pH, microorganisms sunlight persistence metribuzin its effect enzymes. Half-lives (DT50) varied significantly with rate ...

• Fluorescence readings of E. faecalis infected human dentine sections were quenched when treated with oxidizing irrigants. returned to baseline in 24 h. The fluorescence quenching effects agents need be considered using laser as a diagnostic tool assessing the quality root canal debridement or disinfection. This study aimed assess changes characteristics Enterococcus over period h following tr...
