CHEESE MAKINGPROCESSOFCHEDDARING

This article presents the process of chedderizatsii from a technological point of view and the General theory of cheese making. Chedderizatsii described as a process of restructuring of the cheese mass due to the reorientation of relations between multi-molecular associates of milk (casein micelles and fat globules). The algorithmic process chedderizatsii due to the natural cycle of transformation of milk components in the abomasum of calves of milk period. There is an acid-base range (pH 5,3 - 5,1), in which a certain dynamics of interaction of protein, fat, mineral and aqueous phases of milk is programmed. The role of carbonate milk buffer in cheese mass restructuring is shown. In the development of the group's natural rennet cheese with a pronounced process of chedderizatsii curd spontaneously (with the rapid increase in acidity) is structured - is of laminated fibrous structure, which is commonly associated with the structure of the "meat chicken breast", which is a consequenc

Температурная стабилизация фазовой скорости электромагнитной волны в прямоугольном волноводе с многослойной нанокомпозитной сегнетоэлектрической пленкой

A solution is obtained for propagation constant of electromagnetic wave fundamental mode in straightangle waveguide with the cross section partially filled with multilayer nanocomposite ferroelectric film (MNESEP) on a dielectric substrate. The numerical model is based on the scalar form of the finite element method reduced to a homogeneous system of lin-ear algebraic equations with respect to nodal values of the wave scalar for one-dimensional approximation. The nanolayer dielectric properties are determined by barium concentration dependence in composition of BaxSr1-xTiO3 sol-id solution. A calculation program for several dozens of elements of partition along the wide wall of a rectangular waveguide is developed. The results of computer modeling for MNSEP with different number of layers and concentration dependences of barium are given, which allow to stabilize the propagation constant over a wide temperature range. Определена постоянная распространения основной моды электромагнитной волны в прямоуголь­ ном волноводе, поперечное сечение которого частично заполнено многослойной нанокомпозитной се­ гнетоэлектрической пленкой (МНСЭП) на диэлектрической подложке. Численная модель построена на основе скалярной формы метода конечных элементов, приведенного к однородной системе линейных ал­ гебраических уравнений относительно узловых значений волнового скаляра при одномерной аппрокси­ мации. Диэлектрические свойства нанослоев определены концентрационной зависимостью бария в со­ ставе твердого раствора BaxSr1xTiO3. Приведены результаты проведенного по специально разрабо­ танной программе расчета для нескольких десятков элементов разбиения вдоль широкой стенки пря­ моугольного волновода компьютерного моделирования МНСЭП с разным числом слоев и концентрацион­ ных зависимостей бария, позволяющих стабилизировать постоянную распространения в широком температурном интервале.

DIAGNOSIS OF GROUPS OF ELECTRO-RADIO COMPONENTS ACCORDING TO THE TRANSIENT RESPONSES FOR THE DETECTION OF DEFECTS ON THE FUNCTIONAL CELLS

Objectives. A method for diagnosing electronic components with minimally complicated control and measuring instrumentation and the ability to obtain information from internal control points of operating units is developed. Methods. The developed method for control of groups of electronic components presupposes the passage of a controllable influence through a few control points, connected via several electronic components. In addition, each electronic component contributes its share to the transformation of the parameter output, so the discrepancy of its allowable values for the identification of defective electronic component are required to assess the implication of the expected value of the probable defect of each electronic component in the schema with the aim of isolating it. The faulty component in the electronic circuit is identified by the minimum estimated variance, by which the magnitude of the defect will match the expected value of the electronic component parameter. Results. As a result of the control no more than ten groups of electrical components on functional cell matrices can be assessed as having a defective element by comparing the calculated variance values for each electrical component and the corresponding electrical component parameter itself. Conclusion. Diagnosing groups of electric components on transient characteristics for the detection of defects in the functional cell matrices enables efficiency control operations improvement and troubleshooting in the search for modern electronic equipment reliability

INFLUENCE OF LIPID PEROXIDATION PROCESSES ON OXYGEN-TRANSPORT PROPERTIES OF HEMOGLOBIN IN ERYTHROCYTES OF PERIPHERAL BLOOD OF PREGNANT WOMEN WITH CYTOMEGALOVIRUS INFECTION

The article is devoted to the study of activity of lipid peroxidation processes and their influence on oxygen-transport properties of hemoglobin in erythrocytes of peripheral blood of pregnant women with cytomegalovirus infection. Activation of lipid peroxidation processes in pregnant women with cytomegalovirus infection determined by the contents of TBA-active products is accompanied by accumulation of cytotoxic factors - arachidonic acid (1 trimester - up by 31 %, 11 trimester - up by 68 %, 111 trimester - up by 41 %) and lysophosphatidylcholine (1 trimester - up by 85 %, 11 trimester - up by 55 %, 111 trimester - up by 13 %), causes disorders of oxygen-transport properties of hemoglobin in erythrocytes (decrease of total erythrocytes and hemoglobin count), more than double increase of indices of thermolabile hemoglobin at slight decrease of oxyhemoglobin, increase of methemoglobin (1 trimester - up by 60 %, 11 trimester - up by 25 %, 111 trimester - up by 16 %, in comparison with control), that causes decrease of transportation and delivery of oxygen to the tissues and can be the reason of hypoxia
