Although most cheese is consumed as “table cheese,” which may be arbitrarily defined as cheese eaten on its own or as an accompaniment to bread or crackers during meals, significant quantities of cheese are also consumed as an ingredient in cheese-based dishes/snacks in the home, food service, and prepared consumer foods. Notable examples of natural cheeses used in these applications include Cheddar, Mozzarella, and Emmental, with typical dishes including toasted sandwiches, quiche, omelets, pasta, pizza, and lasagna. As an ingredient, pertinent attributes or functionalities of the unheated cheese include crumbliness, slice ability, spread ability, shred ability or grate ability, and those of a heated cheese include overall appearance, flavor, extent of flow, stringiness, fluidity, and oiling-off. The type and level of functionality required depends upon the application (Tables 29.1 and 29.2). Hence, Feta cheese which is crumbly is ideal for tossed salad; Parmesan, which grates very well into small particles, for sprinkling onto lasagna or pasta dishes; and heated Mozzarella, which exhibits moderate flow and the ability to form fibrous strings when extended, for pizza. Nevertheless, the functional attributes, and, hence, suitability of any specific cheese type as an ingredient can vary due to age and degree of maturity, slight differences in make procedure and composition (such as calcium content and pH) [1].<br>In ancient times, cheese was primarily a concentrated form of milk with the benefit of a prolonged shelf life. The high content of fat and protein in cheese made it an energy-rich and nutritious food that was suitable for our hardworking ancestors. Recent advances in nutrition science have highlighted the contribution of cheese to nutrition and health. Cheese is a rich source of essential nutrients; in particular, proteins, bioactive peptides, amino acids, fat, fatty acids, vitamins and minerals. Ripened cheese is free of lactose and therefore suitable for the nutrition of lactose-intolerant individuals [2].<br>The volume of cheese being consumed as an ingredient has greatly increased since the 1970s owing to rapid growth of the food service and prepared consumer food sectors. Simultaneously, there is an increasing emphasis on consistency of functional attributes, especially in terms of cooking performance. For example, cheese may be required to melt and flow sufficiently within a given time at a given cooking temperature, have flow and stretch ability that fall within prescribed limits, maintain desired heat-stability (remain fluid and succulent without crusting) on extended holding at high temperature, or maintain sufficient fluidity (without congealing or becoming stodgy or tacky) while holding following heating (e.g., in a bain-marie). This trend has given rise to the development of ingredient cheese (as distinct from table cheese), which may be defined as cheese manufactured with targeted functionalities designed to optimize quality as an ingredient in specific applications, for example, pizza. The production of ingredient cheese generally involves alteration of the manufacturing protocol and composition so as to impart specific functionalities as specified in business-to-business relationships, and which typically include controlled cooking properties, for example, low-or nonmelt cream cheese or Cheddar cheese; customized degrees of flow, oiling-off and stringiness in pizza-style Mozzarella [1].<br><br></p> Mukhiddinov Q.A, Sultanova Sh.A, Safarov J.E, Aït-Kaddour A.

Therefore, the use of modern information systems in automobiles is one of the factors that improve mechatronic driving and allow the client to offer a new level of automobile control. A comparison of the functionality of specific systems designed to drive a car is considered. Testing of information systems in driving cars proceeds from the following main tasks: reducing the complexity of monitoring the operation of vehicles; management of fuel costs (in particular, consumed by a particular car and a set of cars); unification and optimization of information flows and information resource; implementation of accounting policies in the field of transport operation.</p> Umerov F.Sh.

The authors cited the types and characteristics of alternative fuels, made an analysis in relation to the traditional type of fuel. The authors paid the main attention to the use of hydrogen fuel as a generator of electricity as a fuel cell. Made some calculations from which it is obvious that the use of fuel cells in cars gives positive results in the economic and environmental parameters of cars.</p> Tillahodjaev R.R., Turdiev J.P., Kurbanov A.M.

Transportation is one of the key elements of modern civilization. Its condition and prospects for development depend to a great extent on the possibilities of supplying transport power plants with fuel. The depletion of liquid hydrocarbon fuel reserves and the problems of environmental pollution may put mankind before the alternative - either to reduce transportation or to find new ways of energy supply for transport. Prospects for solving the fuel problem of transport, the main power plant of which is an internal combustion engine, are related to the use of hydrogen in the future.</p> Ismatov J.F., Khakimov J.O., Yangibaev A.I.

Mathematical models have also been developed based on Lagrange's equations of the second kind and an algorithm for optimal control of the processes of hydraulic cylinder functioning using the Pontryagin maximum principle. Numerical Runge-Kutta method is applied to study the optimal parameters of the hydraulic cylinder. A computational experiment was carried out and the optimal parameters of the movement and design of the hydraulic cylinder were determined. On the basis of the obtained functioning parameters and Hamelton's equations, the energy states of the hydraulic cylinder of a universal row-crop tractor with a variable base are determined.</p> Omonov N.N., Masharibov A.R.
