To study the traits of exterior type of firstborn cows of Sumy intrabreed type of Ukrainian Black-and-White milk breed, a research was carried out in the breeding flock in Sumy region.
 The first-calf cows were estimated by the method of linear classification according to the age of 2–4 months after calving in two systems – 9-score, with a linear description of 18 conformation traits, and a 100-point classification system, taking into account four sets of breeding traits that characterize: dairy type, body development, condition of legs and feet, and udder morphological qualities.

Thanks to the breeding work carried out to create the Sumy intra-breed type of the Ukrainian Black-and-White dairy breed, it was possible to increase the level of milk productivity of animals, which today amounts to more than 6.0 thousand kg of milk. The level of milk yield is the main in the system of dairy cattle breeding. The quality indicators of dairy raw materials are also of great importance for the economy of milk production.

Abstract:
Modern dairy breeds of cattle have high milk yields. This is especially true of breeds created using Holstein breed [14]. At the same time, scientists have repeatedly stated that the use of Holstein breeders deteriorates the quality characteristics of milk productivity. Therefore, the influence of conditional blood by Holstein breed significantly affects productivity. However, researchers emphasize that the breed as a genetic factor has a significant impact on milk productivity. This explains the influence of the biochemical composition of milk on the profitability of the dairy industry.

This chapter explores how birth bears on the temporality of human life. Temporally, lived human existence is future-oriented towards death and past-oriented towards birth. When we take our natal orientation towards the past into account, we see that when we project forward and create meaning we are always extending inherited horizons that we have received in and from the past. The chapter also considers whether birth can rightly be said to be a gift given to us by our mothers. Although that view has problems, thinking of birth as a gift illuminates some connections between our natality and the

Abstract:
Stresses in Class 1 branch connections that consist of large bore run pipe with a reinforced branch nozzle should rarely be limited by the run–branch interface stresses. The end of the “branch nozzle – branch pipe” interface is the location on the branch nozzle one would expect to see the limiting stress. Therefore, it is important that reasonable Design Rules are maintained in the ASME Code Section III for the stress analyses of the Class 1 Piping branch connections to avoid over-predicting the “run pipe - branch nozzle” interface stresses. This will allow the analysts to concentrate on load

Abstract:
Abstract Prediction of long-term creep strength is an important issue for industrial plants operated at elevated temperatures, although the creep strength of high Cr ferritic steels depends on their microstructural evolution during creep. The state of microstructure in metallic materials can be expressed as numerical values based on a concept of system free energy. In this study, in order to evaluate long term creep strength of 9Cr ferritic steel containing B, change in the system free energy during creep of the steel is evaluated as the sum of chemical free energy, strain energy and surface e

Abstract:
Abstract Well productivity often declines due to multiple reasons which include skin effect near well-bore area, heavy deposition in tubing, change in wettability etc. This paper presents a methodology to identify the optimal surfactant-solvent composition, followed by field deployment along with case studies of the laboratory designed formulation. The methodology is based on detailed characterization of crude oil followed by preparation of various surfactant-solvent combinations and evaluation of their efficacy in terms of improvement in rheological parameter, interfacial tension, contact ang

Abstract:
In order to extend the boiler lives at Advanced Gas-Cooled Reactor (AGR) nuclear power stations in the UK, new temperature measuring instrumentation to monitor reactor gas temperature has been proposed to install on the bore of an intact boiler tube to provide additional boiler operating data to support the station lifetime extension. This paper details a creep-fatigue crack initiation assessment of the proposed installation of an instrument guide tube within the superheater header using the latest R5 high temperature assessment procedures based on detailed finite element thermal transient str

Abstract:
Abstract In Oil and Gas framework, the need of innovative turbomachineries in terms of efficiency, weight, and flexibility is quickly growing. For these reasons, the new LM9000 is entirely designed with aviation design criteria. It is composed by a gas generator derived from the GE90-115B twin shaft turbofan, coupled to a free power turbine (FPT). Both the gas generator and the FPT use rolling element bearings that contribute to reduce the weight and the complexity of the engine and its auxiliary systems architecture. The free power turbine represents the new element. Due to the FPT dimensions
