The impact of improved water, sanitation, and hygiene (WASH) access on mitigating illness is well documented, although impact of school-based WASH on school-aged children has not been rigorously explored. We conducted a cluster-randomized trial in Nyanza Province, Kenya to assess the impact of a school-based WASH intervention on diarrhoeal disease in primary-school pupils. Two study populations...

We hydrothermally treated monocultures of Escherichia coli, Pseudomonas putida, Bacillus subtilis, and Saccharomyces cerevisiae at isothermal (350 °C for 60 min) and fast (rapid heating for 1 min) liquefaction conditions. Fast hydrothermal liquefaction (HTL) of P. putida and S. cerevisiae produced the highest biocrude yields of 47 ± 13 and 48 ± 9 wt %, respectively. Biocrudes generated via fast...

The aim of this study was to investigate the influence of reaction temperature and wheat straw moisture content on the pyrolysis product yields, in the temperature range of 475-575 °C. Samples of straw with moisture contents from 1.5 wt % to 15.0 wt % were fed to a bench scale Pyrolysis Centrifuge Reactor (PCR). The experimental results show that the changes in straw moisture content have no si...

The purpose of this study was to investigate the reinforcing effect of short E-glass fiber fillers oriented in different directions on composite resin under static and dynamic loading. Experimental short fiber-reinforced composite resin (FC) was prepared by mixing 22.5 wt% of short E-glass fibers, 22.5 wt% of resin, and 55 wt% of silane-treated silica fillers. Three groups of specimens (n=5) we...

Natural dry steam zones (vapour only) are relatively rare; most geothermal systems contain both liquid and vapour and typically follow a boiling point-depth (BPD) relationship. The Nanga Parbat uplift-driven conductive thermal anomaly results in a geothermal system which follows a BPD relationship at shallow levels, but below about 3 km fluid inclusions show that the hydrothermal fluid is dry s...

Sisal leaves which constitute only 2% of the sisal plant have been used in the production of pulp and fiber; the remaining 98% which is mostly of the sisal bole is largely regarded as waste. The bole’s high inulin fraction (2436%) is of particular significance due to its chemical functionality and relative ease of fermentation. utilisationThe objective of this study was to identify properties a...

Peanut, an important oilseed crop, frequently encounters drought stress (DS) during its life cycle. In this study, four previously developed mtlD transgenic (T) peanut lines were used for detailed characterization under DS, at the reproductive stage using lysimeter system under controlled greenhouse conditions. In dry-down experiments, T lines maintained better photosynthetic machinery, such as...

The effect of seaweed liquid fertilizer (SLF) of Sargassum myriocystum on germination, growth and biochemical constituents of Vigna mungo was studied. Different concentrations (5%, 10%, 25%, 50% and 75%) of SLF were prepared using distilled water. A total of 100 seeds were soaked for each SLF concentration for a 24-h period and were later placed in various Petri plates and watered regularly. Wa...

The nutritive value of Pleurotus ostreatus (Jacq. ex Fr.) Kumm., Pleurotus sajor-caju (Fr.) Singer, and Agaricus bisporus (Large) Sign. was determined. Dry matter, moisture, crude ash, protein, fat, cellulose, organic matter, and nitrogen-free extract were 89.7%-90.3%, 9.7%-10.3%, 6.0%-13.7%, 27.8%-41.6%, 0.5%-1.3%, 10.0%-16.2%, 76.0%-84.0%, and 26.7%-36.8% of dry weight, respectively. Mineral ...

There are basically two ways to etch silicon: dry and wet chemical etching. In micromachining, the control of the shape of the structure is accomplished by anisotropic etching through mask openings. The anisotropy of wet chemical etching is related to the crystal structure of silicon, while that of dry etching stems from the momentum of ions impinging the substrate. The latter gives us much mor...
