Abstract In the present study, tannins from stem and root barks of Tessmannia burttii Harms ( Caesalpiniaceae ), a plant species abundantly growing in Tanzania other parts Africa, were investigated for their suitability hides tanning. Tannin powder was extracted at selected temperatures (30, 50 80 °C) influence each temperature on crosslinking capacity evaluated. The interaction mechanism betwe...

However, the acceptance of its usage application sustainable affordable is rare. supports enhances good life without compromising earth’s ecosystem prospects later generations. It energy efficient, environmentally sound, it been controlled by local community with available materials. o...

AIM The red jungle fowl is generally considered as one of the endangered Asian wild Galleopheasants due to man-made encroachment of their habitats, coupled with the effect of disease and disease causing organisms like ticks and tick-borne infections. This study aimed to determine the tick fauna of the red jungle fowl and their predilection sites based on developmental stages. MATERIALS AND ME...

A laboratory study was carried out on anaerobic digestion of vegetable wastes (brinjal, cabbage, carrot, ladies finger) & flowers (jasmine, sunset flower, Roselle, African wattle, Nile tulip flower, silk tree mimosa.) in a 1L capacity of anaerobic digestor using cow dung as an inoculums. The digester was operated in the ratio of 1:1 of substrate to inoculums at RT. The substrate concentrations ...

New techniques have recently appeared that can extend the advantages of grapple yarding to fast-growing plantations. The most promising technique consists of an excavator-base un-guyed yarder equipped with new radio-controlled grapple carriages, fed by another excavator stationed on the cut-over. This system is very productive, avoids in-stand traffic, and removes operators from positions of hi...

Acacia polyphenol (AP) extracted from the bark of the black wattle tree (Acacia mearnsii) is rich in unique catechin-like flavan-3-ols, such as robinetinidol and fisetinidol. In an in vitro study, we measured the inhibitory activity of AP on lipase and glucosidase. In addition, we evaluated the effects of AP on absorption of orally administered olive oil, glucose, maltose, sucrose and starch so...

Plant polyphenols extracted from plants are one of the most abundant biomasses in nature, which are typical water soluble natural polymers. Herein, we reported a facile approach for the synthesis of platinum nanoparticle (PtNP) aqueous colloid by utilizing black wattle tannin (BWT, a typical plant polyphenol) as amphiphilic stabilizer. The phenolic hydroxyls of BWT provide the PtNPs with enough...

The study of Fulani ecotype (indigenous) chicken becomes necessary for proper understanding its potentials future breeding programmes in Nigeria. Sixty adult chickens comprising 22 males and 38 females were sourced from the kraal at Opeji Odeda Local Government area Ogun State used to determine their qualitative quantitative traits. Twenty (20) cocks out original selected randomly population se...

We present a systematic framework for nationwide crop suitability assessment within the UK to improve resilience in cropping systems and nutrition security of population. An initial analysis was performed using data from 1842 crops at 2862 grid locations UK, climate (temperature rainfall) soil (pH, depth, texture) Met Office British Geological Survey. In second phase, additional qualitative qua...
