Background

Currently, there are two ways of administering anaesthesia: either by administering the anaesthetic agents by gas or through intravenous administration. The drawbacks of inhalation anaesthesia are that they can cause side effects, particularly respiratory[1], have a negative impact on...

This invention relates to a method of preparing biological material obtained from a biological sample, more particularly a blood or sputum sample.

Methods for preparing biological material obtained from blood or sputum samples have been known for decades. These methods are based on multiple steps...

This invention relates to a drive circuit and the method for driving a transformer. More particularly the invention relates to a drive circuit and method for driving a transformer which forms part of an ignition system for an internal combustion engine.

In order to improve emissions in petrol...

This invention relates to an ignition system for an internal combustion engine and a method of driving an ignition plug of an ignition system.

In order to improve emissions in petrol internal combustion engines to meet emission standards, the engine needs to be operated with a high exhaust gas...

This invention relates to an ignition plug for an internal combustion engine.

In order to improve emissions in petrol internal combustion engines, the engine may be operated with exhaust gas recirculation (EGR) or lean air- fuel mixtures. However, combustion stability may become unacceptable...

A novel spurious suppression method is applied to suppress undesired harmonics and mixing products in radio frequency (RF) signals that reduce the signal's spurious-free dynamic range (SFDR). The method employs real-time digital signal processing to cancel undesired spurious signals and so improve...

Air quality is a concern worldwide. Consequently, efficient means to monitor air pollutants are critical. Current commercially available carbon-based sorbents used for sampling volatile organic compounds (VOCs) in air typically require solvent extraction prior to analysis and they cannot be re-used...

Researchers at Stellenbosch University have developed a groundbreaking new polymer having permanent antimicrobial properties. The compound can be spun into nanofibers for the production of filter elements or membranes, which successfully filter out micro-organisms and eliminate harmful bacteria.

Short chain fructooligosaccharides (scFOS) are prebiotics used as a food supplement to improve dietary health in humans and animals. FOS are also used in the food industry as low-calorie sweeteners and added to food products to improve their organoleptic properties.

Global demand for FOS is...

The researchers at Stellenbosch University have developed a technology for the radiometric correction of high spatial resolution imagery (aerial or UAV).  The imagery is calibrated to approximate surface reflectance by fusing with concurrent and collocated satellite imagery.  The technique allows...
