Subject of the inquiry: the protective carcass of a cabin of universal wheel tractor-cultivator.
Aim of the inquiry: design procedure working out on durability and the substantiation of strength parameters of the carcass of cabin of tractor of a class 1.4.
Methods of inquiry: Researches were spent by methods of mathematical and experimental modeling of deflections of elements of the bearing carcass of the cabin of the tractor at overturning in quasi-static to statement
The results achieved and their novelty:
- the mathematical model of calculation of the carcass of the cabin of the tractor on durability is made;
- the design procedure of the protective carcass of the cabin of the tractor on durability taking into account process of distribution of a zone of plastic deformation on length and height of cross-section section of elements of the construction of the carcass;
- Dependences strength properties of rod elements of the construction of the carcass from the bend and curvature moment.
Practical value: the cabin design procedure on the durability is developed, allowing at a design stage and operational development of a design with high degree of reliability to receive demanded strengthening characteristics (the Patent for the computer program № DGU 01583). The multiple analysis of the construction of the cabin of tractor TTZ 80.20 is carried out and the new carcass of the cabin of the tractor (the Patent for utility model № 1'AP 00563) is offered.
Degree of embed and economic effectiveness: Results of work are transferred to special design engineering bureau “Tractor” for practical use at carrying out of developmental works on modernization and construction development of new carcass of cabins of tractors.
Sphere of usage: automobile construction and tractor construction.

The article summarizes the author’s observations on the use of the category of voice of the English and Karakalpak verbs. The work opens with a brief overview of the opinions on the category of voice in general. Modern linguistics have spoken about the complexity and importance of the English category of voice. There are many works devoted to this verbal category, but all of them demonstrate contradictory points of view. In our works we have already emphasized that the category of voice is a point of intersection of different levels of language: morphology, syntax and vocabulary. In addition, the complexity of the category of voice is determined by its close connection with the categories of type and transitivity, as well as different degrees of grammaticalization of adjacent ways of expressing similar values. The English passive voice differs from the Karakalpak passive voice, which is used much less frequently and gives way to other expressive means of language. This fact creates some difficulty for the translator and requires a careful comparative analysis of the passive constructions in the English and Karakalpak languages. In this article, we have made an attempt to identify the basic ways of translation of passive constructions from English into Karakalpak.

В имплантологической практике объединение в несъемные ортопедические конструкции естественных зубов с внутрикостными имплантатами ставит ряд задач, от решения которых зависит успех лечения. Но такое соединение повышает риск возникновения осложнений у пациентов, так как анатомические особенности строения пародонта естественных зубов и тканей, окружающих остеоинтегрированные имплантаты, определяют их реакцию на функциональные нагрузки.В данной работе оценена роль ортопедического лечения в общем комплексе лечебно-профилактических мероприятий по предупреждению развития осложнений при протезировании с опорой на имплантаты, рассмотрена оценка предельно допустимых нагрузок на имплантат, прогнозирования эффективности замковых креплений на имплантатах. Впервые с помощью клинико-функциональных и математических методов исследования научно обоснован выбор ортопедического метода лечения дефектов зубных рядов с опорой на дентальные имплантаты в зависимости от оценки эффективности замкового крепления (аттачменов) зубных протезов на естественных зубах и имплантатах. Окклюзионная нагрузка на внутрикостный имплантат зависит от ряда факторов: от количества и локализации имплантатов и естественных зубов, способов фиксациипротезов на имплантатах, длины промежуточной части, характера окклюзионных контактов при жевании, состояния антагонистов и др. В настоящее время для определения величин окклюзионных нагрузок в зонах опор протеза на имплантатах используется математическое моделирование. Установлена предельно допустимая нагрузка, которую может выдержать кость, окружающая имплантат в зависимости от формы и материала имплантата, состояния компактного и губчатого вещества и др. факторов.
Как известно большинство протезов на дентальных имплантатах это несъемные конструкции, а фиксация к абатментам одиночных или опорных коронок мостовидных протезов — винтовая или цементная.

The article presents data on the substantiation of a new design of gaskets for saw gins, characterized by a lightweight type and a composite structure of individual steel elements (disk with splines, rim), welded after preliminary assembly.
The steel structure of the inter-saw gasket, as shown by experimental studies on axial compression, in contrast to aluminum design, is characterized by high strength, less permanent deformation, increased hardness and the ability to maintain performance for a long time under repeated operation without violating the technological conditions of ginning.

В работе приводятся конструкционные особенности уже разработанного, навигационного хирургического шаблона, изготовленного с применением современных компьютерных технологий моделирования и производства.
The article contains material on the use of techniques to stimulate student activity in Russian language classes in connection with the study of constructions with semantics of condition. The author shows how, using examples from literary texts, one can not only develop skills in operating conditional constructions, but also awaken in students the desire to produce their own speech and reveal their creative potential.
