TL;DR: In this article , coal and algal pyrolysis was performed in a rotary kiln with the aim of assessing the effect of coal/algae blending ratio and kiln temperature on the yield and composition of the resultant oils.

Abstract: This research study contributes to the ever-expanding literature by examining multivariate cointegration and causality relationships between electricity consumption, economic growth and other growth determinants for quarterly South African data collected between 1994/Q1 – 2014/Q4. The motivation behind this current research case study becomes apparent when taking into consideration that no previous studies have gone further than bivariate and trivariate analysis in investigating the electricity-growth nexus in South Africa. In conducting our empirical investigation, our obtained empirical results are two-fold in nature. Firstly, we find significant multivariate long-run cointegration relationships between economic growth, electricity consumption and other growth determinants. Secondly, our empirical analysis offers support in favour of the neutrality hypothesis, that is, the notion of no causal effects existing between electricity consumption and economic growth in the long-run. However, we find that exports directly cause electricity consumption whereas economic growth, domestic investment and employment levels causally flow to exports.

TL;DR: In this article, the removal of chromium and nickel ions from the wastewater using magnetite as an adsorbent is studied, and the results show that magnetite particulate ads absorbent is an effective material.

TL;DR: In this paper, the thermal decomposition behavior and kinetics of proteins, carbohydrates and lipids are studied by use of models derived from mass-loss data obtained from thermogravimetric analysis of Scenedesmus microalgae.
