Books on the topic 'Oil ratio'

A revision of the 1989 classic, Enhanced Oil Recovery by Larry Lake, this text, Fundamentals of Enhanced Oil Recovery, retains the original work's emphasis on fractional flow theory and phase behavior to explain enhanced oil recovery (EOR) processes. There is additional coverage on cutting edge (or current) topics, such as low-salinity EOR, steam-assisted gravity drainage, and expanded coverage on thermodynamics and foam EOR. With its frequent reinforcement of two fundamental EOR principles, lowering the mobility ratio and increasing the capillary number, it is an excellent resource for undergraduate classes.

The aim of the study was to determine the effect of feed additives (algae, soybean, and sunflower oil) used in the rabbit feed on: growth indices and slaughter traits, pH, colour, texture, chemical composition, fatty acid profile and oxidative stability (TBARS) of the meat as well as FTO and FABP4 genes expression in the meat’s intramuscular fat (m. longissimus lumborum), depending on the age and sex. The experimental material consisted of Termond White rabbits (n = 160, 80 females and 80 males). Animals were weaned on the 35th day of life, and housed in metal cages arranged in batteries (4 rabbits of the same sex in a cage). From weaning to 12 or 18 weeks of age, the rabbits were fed pellets ad libitum. Animals in the control group (C) received non-supplemented pellets throughout the experiment. In the other groups, the pellet contained 1% algae (A), 3% sunflower oil (OS), and 3% soybean oil(SO).The experimental diets were formulated to have similar protein and energy content. Diets were balanced by lowering the proportion of other feed components. The total share of all components remained at 100%. The results indicate that 3% vegetable oils (soybean or sunflower) supplementation of diets for growing rabbits leads to an increase of body weight and improvement of some of the slaughter traits, while 1% addition of algae to the feed causes deterioration of body weight and slaughter traits. The effect of oil additive depends on the animals’ age. Supplementation of the rabbits’ diet with algae (1%) or sunflower and soybean oils (3%) led to an increase in the dressing percentage of rabbits slaughtered at 18 weeks of age (approx. 3%), but had no effect on the dressing percentage of rabbits slaughtered at 12 weeks of age. Feeding pellets with either 3% vegetable oils or 1% algae additive to the rabbits did not significantly change the chemical composition of the meat. Protein content increased and intramuscular fat content decreased with age, while ash and water content were similar. The feed additives significantly differentiated meat acidity without deteriorating meat quality. Diet modification has not affected negatively meat colour. 24 h after the slaughter, the colour of rabbit meat was similar across the studied feeding groups. Correlation between diet and rabbits’ age was found. Meat texture (hardness, springiness and chewiness) of all rabbit groups slaughtered at 12 weeks of age was similar, and the shear for cewas greater in rabbits fed pellets with algae and soybean oil. At 18 weeks of age, rabbit meat from experimental groups had lower hardness and chewiness, compared to meat of the animals from the control group. Meat shear force was higher in the control group, and from algae-supplemented group. The correlation between diet and age was also found. The use of 3% vegetable oils or 1% algae as feed additives significantly reduced meat oxidative stability. Soybean or sunflower oil (3%) usedas feed additives favourably modified the fatty acid composition of intramuscular fat. Polyunsaturated fatty acids (PUFA) content was increased, including linoleic acid, and PUFA/MUFA ratio was improved. The content of these acids decreased with age. The use of algae (1%) as a feed additive resulted in positive effect on the increase of n-3 fatty acid content (EPA and DHA) in meat intramuscular fat. Algae supplementation improved pro-health properties of meat, with low n-6/n-3 acid ratio (2.5), indicating that diet modification may affect the fatty acid composition of rabbit meat. The influence of diet and age on FTO and FABP4 gene expression in meat intramuscular fat (m. longissimus lumborum) was found. FTO and FABP4 gene expression increased with age and was the highest in the group of rabbits with 1% algae supplementation in the diet. The effect of rabbits’ gender on growth, slaughter traits, meat quality and gene expression in rabbits was not observed. In conclusion, the use of natural feed additives, such as sunflower, soybean oil or algae, can improve the nutritional value of rabbit meat, without changing its chemical or physical properties, and therefore the meat can serve as functional food, with properties beneficial to human health. The results obtained in this study also indicate that the expression of FTO and FABP4 genes in rabbit muscles is regulated by dietary factors and age, which, in addition to cognitive significance, has practical implications for improving technological and dietary quality of rabbit meat.

Evidence for the importance of the long-chain omega-3 polyunsaturated fatty acids in fetal and infant development is growing, as is interest in what constitutes an appropriate intake from sources such as oily fish or dietary supplements for pregnant women and/or infants. Polyunsaturated fatty acids have been implicated in maternal mental health and aspects of infant development, including cognitive and visual function, adiposity, and allergy. Western diets have become imbalanced with regard to the ratio of omega-6:omega-3 fatty acids, and recommendations to correct this imbalance include increasing the maternal intake of oily fish. However, this recommendation needs to be evaluated in light of the increased risk of exposure to contaminants such as mercury. Vegetable oils and cereals are important sources of polyunsaturated fatty acids for vegetarians.

The preprint presents the economic mechanism of investment programs and analyzes its components: specific indicators for evaluating the investment part of developmental programs are proposed; a specific pricing for products manufactured as a result of the implementation of investment projects; a system of financing developmental programs based on the optimal ratio of budget funds, reinvested profits and credit. The empirical base of the study is made up of materials from the petrochemical complex. In this regard, the world trends in the development of petrochemical chemistry and the situation in the petrochemical complex of Russia are considered. Recommendations are given regarding the development of the petrochemical industry of Russia. A multi-criteria optimization model that implements the presented economic mechanism and is intended to form variants of the structure of the governmental program for industrial and regional (territorial) development is developed. The results of a computer experiment are presented. Variants of a conditional program for the development of the Russian oil and gas chemical complex showing the positive impact of the proposed economic mechanism on the structure and indicators of the program are developed.

Abstract The greatest technical discontinuity in history took place between 1867 and 1914. This era was distinguished by the most extraordinary concatenation of scientific and technical advances, the synergy of which produced bold and imaginative innovations resulting in profound socioeconomic impacts. Detailed examinations of these epoch-making advances start with electricity (dynamos, steam turbines, transformers, light bulbs, electric motors, power plants, transmission) and internal combustion engines (automotive designs by Otto, Diesel, Daimler, Maybach, Benz, Ford, aeroengines) before looking at inventions in material production, from metallurgy (affordable steel, aluminum) and cement to powerful explosives and the synthesis of ammonia, and at advances in information (from papermaking and typesetting to photographs and movies) and communication (from telephones, phonographs and records to radio). Post-World War I inventions and innovations transformed all of these techniques by making them more efficient, durable, reliable, affordable, and environmentally more acceptable and brought new accomplishments in energy conversions (oil and gas industry, gas turbines, nuclear electricity generation), materials (new ways of steel production, plastics, herbicides, pesticides, silicon), rationalized production (automation, robotization, quality control), and transportation (freeways, jetliners, rapid trains, large tankers, container shipping), while advances in solid-state electronics enabled the age of computing, microprocessors, and access to instant global communication and information (personal computers, mobile phones, World Wide Web). The Age of Synergy and the post-1914 technical transformations created a new, increasingly anthropogenic world of high-energy societies whose most worrisome obverse has been large-scale environmental degradation.
