A preliminary assessment for the use of metabolic inhibitors to evaluate the biodegradation potential of soil
… (Na.7N1o04) and 2-Bromoethane sulfonic acid (BESA), which inhibit sulfate reduction and methanogenesis, respectively. Denitrification was suppressed by the absence Of sodium nitrate (NaNO3) in the microcosm dilution water. Both Newport News and Blacksburg soils were found to be dominated by …

An examination of the price reaction to the announcement of bond issues by Johannesburg Stock Exchange listed companies on the Bond Exchange of South Africa
… companies, on The Bond Exchange of South Africa (BESA), during the period 2000 to 2008. The study is an event study that uses the market model to generate expected returns. The average abnormal returns are standardised by their time series standard errors of regression and tested for significance …

Developmental patterns of Spanish grammatical morphemes and mean length of utterance in bilingual children
… accuracy was determined by performance on the BESA (Bilingual English Spanish Assessment) (Peña, Gutiérrez-Clellen et al., in preparation). Mean length of utterance in words (MLUw) data was collected from language samples. The average percent accuracy of grammatical morphemes was calculated …

Variations in the biodegradation potential of subsurface environments for organic contaminants
… sulfate) or metabolic inhibitors (molybdate, BESA) to promote different pathways of anaerobic microbial metabolism (nitrate respiration/denitrification, sulfate reduction, or methanogenesis). In unamended systems, biodegradation rates varied considerably between sites. Methanol and phenol were …

Kardiosensibilität, Emotionen und kortikales Geschehen
… Methoden hinweg (EEG, Dipolanalyse nach BESA, fMRT) wurde eine Aktivierung in den beschriebenen viszeralen Regulationsstrukturen gefunden, welche zudem mit der Kardiosensibilität positiv korrelierte. In der vierten Studie wurde das Zusammenspiel von Emotionen und Kardiosensibilität bei …

The rights of an employee to participate in Trade Union matters
Labour relations and the law relating to employment in particular has now more than ever before assumed a very significant place in the policy and legal frame work of how the employer -employee relationship should be.' There are fundamental questions in labour relations that employers and employees …

Regulation of ict-based broadcasting in the digital age:a case of Zambia
Zambia has experienced significant change in the broadcasting sector due to technological advancements while the regulatory framework that was framed in analogue age has remained unchanged. Therefore, ICT-based broadcasting remain largely unregulated. This study focuses on how to regulate ICT-based …

Biodegradation of organic contaminants in subsurface systems: kinetic and metabolic considerations
… TBA, whereas, inhibition of methanogenesis with BESA slowed the degradation rates. The addition of nitrate did not affect the biodegradation in Blacksburg soil. In the Newport News soil, all of the test compounds were biodegraded at substantially higher rates than was observed in the Blacksburg …

Prevalence of pyschiatric disorders in HIV positive patients at Chilenje Clinic in Lusaka Zambia
Psychiatric disorders occur frequently in people living with HIV. Most of them go undiagnosed and therefore untreated, despite the negative consequences they have on HIV spread, progression and management. The aim of the study was to determine the prevalence of psychiatric disorders in HIV positive …

Developing a national mine closure risk and opportunities atlas in GIS for South Africa
… While the impact of mine closure is well-known (Besa, et al., 2019), quantifying the extent of its impacts is not straightforward. This is particularly relevant in South Africa, where impacts may be localised due to variations in mining host community size, location, physical environmental …

Application of Control Allocation Methods to Linear Systems with Four or More Objectives
Methods for allocating redundant controls for systems with four or more objectives are studied. Previous research into aircraft control allocation has focused on allocating control effectors to provide commands for three rotational degrees of freedom. Redundant control systems have the capability …

Battery-Electric-Bus Transit System Design
The increasing availability of battery-electric buses (e-buses) as a sustainable alternative for public transportation has sparked considerable interest in recent years. With a notable decrease in lithium-ion battery prices, e-buses have become a competitive option in terms of the total cost of …
