Engineering And Various Disciplines Engineering applies the working principles and theories of science, mathematics and other experiential indications for designing, analyzing and crafting technological solutions acquainted with safety, human factors, physical laws, practicality, and cost. Engineering is one of the most opted fields of the profession in India. In the last two decades, the number of engineering colleges in India has augmented largely. The establishment of engineering colleges across the country has resulted in the upsurge in the number of aspirants for pursuing professional education as well. There are various branches of engineering, some of the major engineering disciplines are given below: Chemical engineering: Chemical engineering is that discipline which deals with the application of chemical, physical and biological sciences for the purpose of transforming raw provisions and chemicals into more precious customs. The different sub-Disciplines of chemical engineering are: Bio-molecular : This field emphasizes the manufacturing of molecules. This field includes genetic, biochemical, and engineering of DNA, RNA. Materials : This field focuses on the insight and knowledge about the materials and also on its application for engineering. Some of the sub-fields of this branch include Metallurgical, Ceramic, Polymer, Crystal, and Biomaterials. Molecular : This discipline is focused on the manufacturing of the molecules. Process : This field focuses on the designing, operation, controlling and optimization of chemical processes. The sub-branches are Petroleum refinery, Plastics, Paper, and Textile. Corrosion : This field applies scientific knowledge, natural laws and other resources for the designing and implementing materials and to manage corrosion. Civil engineering: The discipline of engineering comprises of the designing, constructing and maintain the naturally built as well as physically built environment. The various sub-disciplines of civil engineering include: Environmental : This field applies the principles of engineering for the improvement and protection of the environment. Ecological, Fire protection, Sanitary, Wastewater, Municipal or urban, are some of the major sub-disciplines of environmental. Geotechnical : This stream concerns with the behavior of the earth materials at the site of the projects. Mining engineering and Foundation (engineering) are the main sub-branches of this field. Mining : This field is related to the extraction and processing of the minerals from naturally happening surroundings.
