Abstract: Techniques and systems for maintaining a plasma processing kit consisting of protection and shielding elements without causing damage are introduced. The elements may be made of aluminium, polysilicon and quartz and may be coated with silicon. The surfaces of the elemants show a specified roughness. Precision cleaning and recovery of the contamined kit components of a plasma doping (PLAD) system is used, to extend the life and reusability of the components. The methods described cover the stages of inspection, pre-cleaning, mechanical processing and texturing, post-cleaning, clean-room class cleaning and packaging of the components consisting of quartz, aluminium and/or silicon. Techniques described employ the combination of a variety of means (primarily chemical and mechanical) to achieve the desired levels of cleanliness. The result obtained by methods that include Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and Laser Particle Count affirm the efficacy of these techniques.

Abstract: A method for improving the half-life of milk comprising the step of: a) contacting milk with an antibody raised against at least one of the following: i) a molecule required for survival by at least a micro-organism that is responsible for reducing the half-life of milk; ii) a molecule required for growth by at least a micro-organism that is responsible for reducing the half-life of milk; iii) a molecule required for survival by at least a micro-organism that aids other micro-organisms to reduce the half-life of milk; iv) a molecule required for growth by at least a micro-organism that aids other micro-organisms to reduce the half-life of milk.

Abstract: A method of inducing the sustained release of antibodies in milk comprising the step of: a) implanting at least one antigen releasing device adjacent to, within close proximity of or within at least one supramammary lymph node, wherein in use the antigen releasing device releases an antigen into the tissue area around the supramammary lymph node which stimulates antibody secretion into a mammary gland.
