South Africa has experienced massive urbanisation and socioeconomic development over the past two decades. Concomitantly, national energy policy focuses on provision of modern fuels, notably electricity, for domestic use. Given this environment development, we examine pertinent literature policies from fuelwood use, value, sustainability to understand how it might have changed in tandem with sh...

South Africa's natural resources and ecosystems are negatively affected by Invasive Alien Plants (IAPs). We used a life-cycle approach to assess the environmental socio-economic impacts of using IAPs for electricity generation in Africa or exported Netherlands. Supply chain greenhouse gas (GHG) emissions from pellets, excluding land use change-related GHG emissions, 31.5 gCO2eq MJ?1 31.2 An add...

This paper 1 describes a series of statistical meta-tests for comparing independent contingency tables for different types of significant difference. Recognising when an experiment obtains a significantly different result and when it does not is frequently overlooked in research publication. Papers are frequently published citing ‘p values’ or test scores suggesting a ‘stronger effect’ substitu...

One of the issues associated with supply electricity is its generation capacity, and this has led to prevalent power cuts high costs usage experienced in many developing nations, including South Africa. Historical research shown that annual rate increase for grown at an alarming since 2008 and, some years, as much 16%. The objectives study are estimate cost analysis twenty-nine residences Unive...

Let A be a local ring with 2 invertible. It is known that the localization of the cohomology ring H∗ ét(A,Z/2) with respect to the class (−1) ∈ H1 ét(A,Z/2) is isomorphic to the ring C(sperA,Z/2) of continuous Z/2-valued functions on the real spectrum of A. Let In(A) denote the powers of the fundamental ideal in the Witt ring of symmetric bilinear forms over A. The starting point of this articl...

An experiment was conducted to compare two common methods of estimating bone ash from growing broiler chicks (A = autoclaving; B = boiling/extracting). Ross x Ross 1-d-old broiler chicks were fed a corn-soy, phosphorus-deficient diet (22.7% CP, 1% calcium, 0.22% non-phytate phosphorus), with 0, 750, 1,500, 3,000, or 6,000 units of phytase (FTU) to produce bones with a range of ash. The methods ...
