Millions of work-related accidents occur around the world each year, some of which lead to death and others to disability and debilitating injuries. HSE consists of three terms: Health, Safety, Environment, which has been a management tool to control and improve the performance of health, safety and environment in all development programs and industrial projects …
In the electricity industry, if the safety of public electricity is not observed, the risk of electric shock is inevitable. Therefore, before touching the wires or electrical devices for repair or any inspection, the electricity must be cut off in the circuit and make sure that there is no electricity and the presence or absence …
Background and purpose: Energy recycling from waste is a suitable method for waste management and clean energy production. The aim of this study was to investigate the anaerobic digestion of food waste by microwave preparation at different times and capacities, which ultimately increases anaerobic digestion and methane production.
Consumption of large amounts of histamine with food causes histamine poisoning in consumers. Not much information is available on the content of histamine in various foods in the country. At present, histamine levels have been measured in samples of foods consumed in the human diet that can contain histamine based on source information.
Alcoholic fermentation is carried out on a large scale by culturing the yeast of the fungal fungus (Sacharomyces Cerevistac) in special fermentation containers with primary yeast dough (primary fermenter). The desired yeast culture mass is then transferred to fermentation jars containing molasses diluted with water and the pH is adjusted to 4.5.
The Covid-19 crisis will affect innovation. However, since innovation is a key factor for corporate strategy and national economic growth strategies, it is hoped that innovation will not decline as much as the economy has collapsed.
The scientific concept of reverse osmosis is based on the principles of mass transfer phenomenon. The difference in concentration is also the driving force of mass transfer between two streams with different concentrations. Understanding the phenomenon of reverse osmosis requires understanding the phenomenon of mass transfer based on osmotic pressure between two streams with different …
Steronize Sterilization is the process by which microorganisms and their transmitters, including fungi, bacteria, bacteria, and viruses, are removed from the surface of objects. The sterilization process, depending on the type of equipment required for sterilization, includes heat, dry (four), heat, wet (autoclave), chemical, radioactive (radio gamic) and plasma autoclave (by oxygen peroxide and autoclave …
One of the most important reactions of fat systems is oxidation. Occurrence of any oxidation in food is considered undesirable and leads to a decrease in the quality and shelf life of food products. Synthetic antioxidants indicate their toxicity, high production costs, and low efficiency against some natural antioxidants such as tocopherols. For this reason, …
The word yeast with Indo-European roots means boil or bubble. Pasteur showed that the addition of oxygen bubbles to the liquid yeast medium increases cell growth. But fermentation is inhibited. This observation was later referred to as the Pasteur effect. Yeasts use organic compounds as an energy source and do not need sunlight to grow. …
