HFreq EA treatment (80–120Hz) resulted in a marginally significant difference (SC) in HRV indicators (increased HF, decreased LF norm, increased HF norm and decreased LF/HF) when compared to LFreq EA treatment (20–40Hz), ...
This study evaluated the impacts of different control techniques on tsetse and animal African trypanosomiasis (AAT). To appreciate the selection and use of different control measures under different circumstances, it was ...
Schweitzer, Joachim-Klaus(University of Pretoria, 1998)
The aims of this study are twofold. First is to investigate the potential link between the predominantly volcanic Dullstroom Basalt Formation and the Rooiberg Group (both units formerly considered as part of the Transvaal ...
Richter, Trevor Aubrey(University of Pretoria, 1998)
I investigated reproduction in springbok (Antidorcas marsupialis) to determine whether the basic physiological system that underpins seasonal reproduction exists in this putatively aseasonal ungulate. In addition, I examined ...
Rossouw, Wessel Johannes(University of Pretoria, 1983)
In the study of field-theoretical problems a good deal of effort is devoted to the formulation of the governing equations. In addition to these equations, subsidiary conditions, such as boundary conditions, are required ...

Staphylococcus pseudintermedius is an important opportunistic commensal bacterium, often correlated with dermatitis and otitis in small animals. The emergence and rapid expansion of methicillin resistance giving rise to ...
Reichhardt, Friedrich Johannes(University of Pretoria, 1989)
The transition from the lower to the upper critical zone and associated rocks (LG 6 - UG 1) has been investigated geochemically and petrographically. This well-layered and ·1ithologically heterogeneous succession is explained ...
Chromosomal and molecular parameters were used to determine intraspecific and interspecific relationships of three species of the order Hyracoidea. A diploid chromosome number of 2n = 54 was found to be conserved in all ...
Zwartkloof is situated in a structurally complex area where structural control of hydrothermal fluorite mineralisation plays a dominant role in the character, and therefore economic viability, of the deposits in Rooiberg ...
Brink, Anthony Berrange Antill(University of Pretoria, 1977)
The object of this thesis is to demonstrate that a knowledge of the stratigraphic unit occupying a site provides a basis for making broad generalisations regarding likely terrain and foundation conditions which may be used ...
Pistorius, Pierre Anton(University of Pretoria, 1999)
Demographic parameters from a 14-year mark-recapture program on southern elephant seals at Marion Island were investigated. Using the computer package MARK, first year survival was estimated at 0.58 and 0.62, and equated ...
Pienaar, Barendina Jacoba(University of Pretoria, 1992)
Taxonomic investigation of Vigna Savi in southern Africa indicated the diagnostic
importance of ridging of stems, pubescence type, stipule shape, presence or
absence of heterophylly, extrafloral nectaries, structure of ...
Peyrot, Belinda Margaret(University of Pretoria, 2020)
The Gs/GD (goose/Guangdong) highly pathogenic (HP) H5 influenza virus detected in China in 1996 has since evolved into genetically distinct clades and subclades. In June 2017, clade 2.3.4.4b H5N8 highly pathogenic avian ...
The International Standard Bovine Tuberculin (ISBT) was confirmed for use in 1986 and serves as an internationally accepted reference for calibration and quality control. The World Health Organization has been involved in ...
Univariate and multivariate analyses were performed on 17 cranial and dental measurements taken from cytogenetically identified specimens of Mastomys natalensis and M coucha. Interpopulation and intrapopulation variation ...
Ochai, Sunday Ochonu(University of Pretoria, 2020)
Anthrax has a global distribution and it is enzootic in Kruger National Park (KNP) in South Africa and Etosha National Park (ENP) in Namibia. These parks share some similarities such as hosts species and both have endemic ...
Culicoides Latreille (Diptera: Ceratopogonoidae) biting midges are found throughout most of the world. As proven vectors of viruses, nematodes and protozoa of medical and veterinary importance they have a negative economic ...
Antimicrobial resistance is a global challenge that risks rendering currently available antimicrobial drugs ineffective. Antimicrobials are routinely used in feedlot systems as prophylactic, metaphylactic and therapeutic ...
The Southern Ground-Hornbill (SGH) is the largest bird species that breeds
cooperatively and the only entirely carnivorous hornbill. Currently, there are only an
estimated 417 breeding groups in South Africa. As the bird ...
