The objective: to study the psychological characteristics of women’s status in one of the most common complications of pregnancy - the threat of termination of pregnancy, depending on the level of stress load. Patients and methods. We have studied the psychological status (the Holmes-Rahe level of psychosocial stress, the Spielberg-Hanin level of anxiety, V.I.Dobryakov’s related to a pregnancy test, diagnosis of psychological defense mechanisms, assessment of quality of life) 60 pregnant women with threat of premature birth in the third trimester of pregnancy. Surveyed women were divided into 2 groups: group 1 included 30 pregnant women – forced migrant of Donetsk and Lugansk area and 2 group – 30 pregnant women who resided in Kiev. Results. At the same clinical picture of the threat of premature birth we detected discrepancy between the subjective assessment of their condition in women – forced migrants: a high level of situational and personal anxiety, decrease in physical (physical functioning, role-physical functioning) and psychological (social functioning, role emotional functioning) health, doubtful and pathological subtypes of gestational dominant. This creates prerequisites for complications of pregnancy, childbirth and postpartum future period and requires the participation of psychologists in the work with this category of patients. Conclusion. So, revealed a discrepancy between the objective clinical signs similar obstetric pathology (on the example of threatened abortion) in pregnant women with different levels of stress load and their subjective evaluation of their condition that affects their psychological status. This should be reflected in individually tailored therapy and be mainstreamed into the work of obstetricians and gynecologists with these patients, and requires mandatory participation of psychologists in the work with this category of patients. Key words: pregnancy, the threat of premature birth, stress, psychological status.

This paper discusses the experimental examination of anisotropic steel-made samples subjected to a static stress load. A nondestructive testing (NDT) measurement system with a transducer, which enables observation of local hysteresis loops and detection of samples’ inhomogeneity, is proposed. Local hysteresis loops are measured on two perpendicular axes, including one parallel to the rolling direction of the samples. The results confirm that the selected features of the local hysteresis loops provide important information about the conditions of ferromagnetic materials. Furthermore, it is shown that the selected parameters of the statistical analysis of the achieved measurements are beneficial for evaluating stress and fatigue changes induced in the material.

Record Data

This study described the decrement in accelerations, decelerations and dynamic stress load (DSL) between quarters in elite hurling. GPS (10-Hz) were used to record data from 42 players over 22 games (2018–2020 season). The number of accelerations and decelerations and DSL between quarters were assessed. Accelerations and decelerations were greater in Q1 than Q2 (ES = 0.28 and ES = 0.44, respectively), and Q4 (ES = 0.57 and ES = 0.60, respectively), and in Q3 compared to Q4 (ES = 0.50 and ES = 0.44, respectively). The DSL was 56 ± 21 AU in Q1, 56 ± 20 AU in Q2, 52 ± 20 AU in Q3 and 56 ± 24 AU in Q4. There was a decrease in DSL in Q3 compared to Q1 (ES = −0.20) and Q2 (ES = −0.20). Each position experienced a temporal decrease in at least one quarter (ES = 0.43–1.46) in all metrics except full-backs’, half-backs’ and full forwards’ accelerations, midfielders’ decelerations and midfielders’ and half forwards’ DSL. Current data show temporal decrements in running performance in Q2 and Q4 and DSL in Q3. Players should be conditioned to minimize the drop-off in running performances following the third quarter.

Different Thickness

Residual stress (RS) pattern of thick T-joint welds, which directly affects fatigue life, varies considerably depending on the thickness and number of passes. Nowadays, most approaches to predict fatigue life do not consider RS real value due to the difficulty of estimating them, hence, they tend to be conservatives. However, recent works have demonstrated that considering RS the conservative error in life prediction can be reduced down to around 15%. In the present work, the fatigue performance of multipass T-joints of S275JR plates for a thickness range from 20 to 60mm is evaluated considering RS. It is observed that maximum RS value for thick plates decreases progressively (down to 66% of yield stress). Consequently, fatigue performance of different thickness T-joint samples subjected to the same stress load cycles varies considerably in the HCF regime.

Cows’ milk productivity determining method of includes: determining the amount of milk during control milking, milk sampling and analyzing its fat and protein content for each milking, they are the same indicators for the day; calculating the conversion coefficients of milk amount and the mass fraction of fat and protein for each milking into daily indicators. Then one control milking is performed per day, and the same indicator is calculated for the same type of feeding, maintenance, and milking based on its indicators multiplied by the Corresponding coefficient. The time intervals between milking being unequal, milk productivity is more accurately determined by a single milk yield after a longer interval between them. For this method, milk cows are taken from the tenth day of lactation and more. The method allows reducing labor costs and working hours of operators and laboratory assistants to daily determine the dairy productivity of cows, as well as to reduce the stress load on animals.
