Wide Format Ceramic Stones Based on Coal Mining Screenings | Chapter 1 | Research and Developments in Engineering Research Vol. 3

 This item presents the results of scientific research and laboratory experiment of the use of screenings from the Angren bitumen basin in the production of absorbent large-plan wall stones. In current years, pebbles from the Angren mine have been actively intentional as a raw material for absorbent ceramics. Interest in this bitumen residue as a raw material for the result of wide layout building stones has raised significantly. Energy preservation measures are more cost-effective than those that involve the growth of new energy beginnings. In light of economic reforms and unfavourable referring to practices or policies that do not negatively affect the environment conditions in the grown countries of the world, the intelligent use of fuel, raw materials, and additional material resources is increasingly main for the development of ceramic result. In this regard, the problem of gettv large-format potteries in the production of obstruction materials is a particularly crucial and unresolved question. The most significant factor moving the level of consistency is noticed with an increase in the sintering temperature and an increase in the grade of grinding of the coal hide. The moulding soil used to create wall grains has been assign attempts to change its composition. As a result, it was likely to produce a lot of heat-insulating, multi-slit obstruction stones, which is individual of the most hopeful developments in the field of strength-efficient construction.

Optimization of Camel Milk Cheese Processing Using Protease from Latex (Ficus carica) | Chapter 3 | Research Aspects in Agriculture and Veterinary Science Vol. 5

 The goal of this work was to look for new plant peptidases with milk-clotting activity in camel milk in latex fractions from Ficus carica, which might be used as rennet replacements. Fast Protein Liquid Chromatography was used to fractionate latex from fig trees to make the enzymatic preparation (FPLC). The milk is pasteurised at a low temperature and cooled, then added a culture of lactic starters isolated from artisanal fermented milk, followed by an enzymatic preparation of latex; the mixture is incubated for 24 hours at 37°C; the whey is drained to obtain a cheese curd; and finally, the mixture is cooled to obtain a fresh cheese. The cheese yield was evaluated using various fraction doses, and it was discovered that 1 ml of the extract in 100 ml of camel milk had a 15% yield. Camel milk cheese was found to be more acidic, richer in protein (50,04 g/l) and phosphorus (0.199 g/l), but less loaded with total mesophilic flora when compared to cow milk cheese in terms of physicochemical and microbiological characterisation. When compared to cow milk cheese, camel milk cheese has higher levels of fat-soluble vitamins (retinol, K2, and Tocopherol), as well as a higher quantity of ascorbic acid (6.189 mg/kg). Oleic acid (28.4%) is the most abundant fatty acid in camel milk cheese, followed by palmitic acid (27.1%) and stearic acid (2.4%). (23.6 percent ).
