TYPES OF STERILIZATION
ABSTRACT
The act of destroying microorganisms on and in an object has been emphasized. Sterilization is primarily used to prevent food and other substances from spoiling. These living microorganisms often spread deadly diseases in humans and animals. They can be destroyed either by chemical substances or by physical agents. Heat and irradiation are the two types of physical agents that can destroy such microorganisms. This paper revealed the different Types of Sterilization and its method .Discussed are the Sterilization, Types of Sterilization, methods of sterilization, sterilization equipment and finally conclusion.
CHAPTER ONE
1.0 Introduction
Sterilization (or sterilisation) is a term referring to any process that eliminates (removes) or kills all forms of microbial life, including transmissible agents (such as fungi, bacteria, viruses, spore forms, etc.) present on a surface, contained in a fluid, in medication, or in a compound such as biological culture media. Sterilization can be achieved by applying the proper combinations of heat, chemicals, irradiation, high pressure, and filtration. The term has evolved to include the disabling or destruction of infectious proteins such as prions related to Transmissible Spongiform Encephalopathies (TSE).
Sterilization destroys all microorganisms; including bacterial endospores.Sterilization should be used for instruments, surgical gloves and other items that come in direct contact with the blood stream or normally sterile tissues (Spaulding 1939). It can be achieved by high-pressure steam (autoclave), dry heat (oven), chemical sterilants (glutaraldehydes or formaldehyde solutions) or physical agents (radiation). Because sterilization is a process, not a single event, all components must be carried out correctly for sterilization to occur. To be effective, sterilization requires time, contact, temperature and, with steam sterilization, high pressure.

Based on these findings, it was suggested, among other things, …
Can the material for “The Nature and Roles of Faith and Reason in the Life of a Christian” be used as a guide for Religious Studies Project?
Yes it can be used — Faith and reason are like two wings on which the spirit rises to the contemplation of truth. There is no incompatibility between the two, but rather an ultimate harmony. Faith is not opposed to reason; rather it requires the full development of reason. And reason itself requires faith in order to strengthen and guide it. The aim or purpose of the study is to assess the Nature and Roles of Faith and Reason in the Life of a Christian. In achieving this aim, the following specific objectives were laid out to expose the nature and roles of faith and reason in our lives, how they influence and have need of one another in the attainment of truth, and unveil the …
Can the material for “Design and Implementation of Text to Speech Application for Vision Impaired Students” be used as a guide for Computer Science (CS) Project?
Yes it can be used — A Text-to-speech application is a synthesizer software that converts text into spoken word, by analyzing and processing the text using Natural Language Processing (NLP) and then using Digital Signal Processing (DSP) technology to convert this processed text into synthesized speech representation of the text. The vision impaired students makes a lot of mistake during typing because they just assume whatever there are typing is right, this lead to the development of Text-To-Speech application. Here, we developed a useful text-to-speech synthesizer in the form of a simple application that converts inputted text into synthesized speech and reads out to the user which can then be saved as an mp3.file. Observation and interview were deployed to gather information used in developing this …
Is the topic “Effect of Telfairia Occidentalis on Haematological Parameters in Albino Rats” recommended for Biochemistry Project?
Yes it is highly recommended — Telairia Occidentalis (Pumpkin) is a tropical vine grown in West Africa and a leaf vegetable. The leaves and seeds are the edible parts of the plant and are used in every day meals by incorporation into soup and stews. The study identifies the Effect of Telfairia Occidentalis on Haematological Parameters in Albino Rats. In achieving this aim, the following specific objectives were laid out to examine the haematological effect of Albino Rats fed Telfairia Occidentalis on Haematological Parameters, analyze the biochemical parameters of haematological and investigate the experimental process of Albino Rat feeds. The effects of the aqueous extract of Telfairia Occidentalis leaves on the haematological parameters of Albino rats were investigated. A total of 36 rats were used for …
