Uticaj faktora 'genetska vrednost oca' na implementaciju genetskog potencijala indikatora 'proizvodnja mleka u maksimalnoj laktaciji' kod krava jaroslavske rase

Dairy products are the main food elements of the man. Milk is the sole food for infants and it plays an important role in feeding of the sick, convalescent, and healthy adults. The Yaroslavl Region is a leading region of the Yaroslavl cattle breed. Therefore, the aim of our research was to determine the strength and reliability of the influence of the factor 'genetic value of the sire' on productive characteristics of animals as a factor that helps to increase the productivity of animals. When we determine the strength of the influence of factors for statistical data we used the procedure of generalized linear models (General Linear Models - GLM), and evaluation components of phenotypic variation attributes were analyzed by multivariate dispersive analysis. Our research has allowed to allocate bulls with genetic value which has the improving effect. Using the recommended lines the farmers of the Yaroslavl region may increase productive characteristics of animals and the profit of the farms and improve the efficiency of breeding.Mlečni proizvodi su glavni elementi ishrane čoveka. Mleko je jedina hrana za odojčad i igra važnu ulogu u ishranu bolesnika, rekovalescenata i zdravih odraslih osoba. Jaroslavski region je vodeći region u gajenju istoimene - jaroslavske rase goveda. Dakle, cilj našeg istraživanja bio je da se utvrdi snaga i pouzdanost uticaja faktora 'genetske vrednosti oca' na produktivne osobine životinja kao faktor koji pomaže da se poveća produktivnost krava. Da bi smo odredili snagu uticaja faktora podatke koje smo koristili, podvrgli smo u proceduri obrade putem generalnog linearnog modela (Opšti Linearni modeli - GLM). Komponente evaluacije fenotipske varijacije atributa su analizirane putem multivarijacione disperzivne analize. Naše istraživanje je omogućilo da se izdvoje bikovi sa genetskim vrednostima koje imaju efekat poboljšanja željenih svojstava populacije. Upotrebom preporučenih linija odgajivači goveda u jaroslavskoj oblasti mogu povećati proizvodne performanse životinja. Sve ovo void ka povećanju profita, a time otvara mogućnost za dalji napredak u proizvodnji

Raman Structural Study Of Olefin Blends

We carried out detailed Raman structural study ofmelt-mixed blends of linear low-densitypolyethylene (PE) and isotactic polypropylene (PP).The relative content of PE in the PE/PP blendsvaried from 13 to 75 %. We show that Ramanspectroscopy can be effectively used for aquantitative analysis of phase and conformationalcompositions of these blends. The changes in thesecompositions due to changing the content of theblend components are discussed. Also, we studied astructure of the amorphous phase of reactor blendsof PE with random ethylene/1-hexene copolymer(CEH)

Прогнозирование развития фатальных и нефатальных исходов у пациентов с артериальной гипертензией пожилого возраста

An integrated approach to the assessment of the health status of older patients with current positions of geriatric syndromes and defined contribution syndrome of cognitive impairment, anxiety-depressive syndrome in the medium-term forecast of the lethal and non-fatal outcomes. Study of survival using the Kaplan-Meier showed statistically significant differences in the examined patients with hypertension in older age groups who are serving on a cottage territorial center of social security of the population, compared with respondents unorganized population (criterion Gehana-Wilcoxon p = 0,04; p = Cox 0,05). The probability of lethal outcomes in patients with hypertension in older age groups has increased 10, 13 times (95% CI 1,2-81,8, p <0.05) if the patient is not taking antihypertensive medications. The presence of cognitive dysfunction syndrome (clock drawing test less than 8 points) increases the risk of death by 1,36 times, anxious-depressive state (geriatric depression scale more than 5 points) – 1,12 times. A model of logistic regression predicting the likely medium-term development of the lethal outcomes in patients with hypertension in older age groups with regard to the main geriatric syndromes is constructed. The sensitivity of the model was 89%, specificity - 94%.Предложен комплексный подход к оценке состояния здоровья пациента пожилого возраста с учетом современных позиций гериатрических синдромов и определен вклад когнитивных нарушений и тревожно-депрессивного синдромов в прогноз развития фатальных и нефатальных осложнений.

Наличие синдрома когнитивных нарушений (тест рисования часов менее 8 баллов) повышало вероятность развития летального исхода в 1,36 раза, тревожно-депрессивного состояния (ШДПВ более 5 баллов) – в 1,12 раза. Построена модель логистической регрессии вероятного среднесрочного прогнозирования развития летальных исходов у пациентов с артериальной гипертензией старших возрастных групп с учетом основных гериатрических синдромов.

Raman structural study of random olefin copolymers

In this work we present Raman study of random copolymers of ethylene and propylene with a number of α-olefins, and investigation of the relationships between the spectral characteristics of the Raman lines and the copolymer structural properties. For both the copolymers we observed rapid decrease in the crystallinity and conformational order as the content of the incorporated monomer increases

Observation Of A High-energy Cosmic-ray Family Caused By A Centauro-type Nuclear Interaction In The Joint Emulsion Chamber Experiment At The Pamirs

An exotic cosmic-ray family event is observed in the large emulsion chamber exposed by the joint at the Pamirs (4360 m above sea level). The family is composed of 120γ-ray-induced showers and 37 hadron-induced showers with individual visible energy exceeding 1 TeV. The decisive feature of the event is the hadron dominance: ΣEγ, ΣE(γ) h, 〈Eγ, 〈E(γ) h〉, 〈Eγ·Rγ〉 and 〈E(γ)·Rh〉 being 298 TeV, 476 TeV, 2.5 TeV, 12.9 TeV, 28.6 GeV m and 173 GeV m, respectively. Most probably the event is due to a Centauro interaction, which occured in the atmosphere at ∼700 m above the chamber. The event will constitute the second beautiful candidate for a Centauro observed at the Pamirs. © 1987.1901-2226233Bayburina, (1981) Nucl. Phys.

Observation Of Very High Energy Cosmic-ray Families In Emulsion Chambers At High Mountain Altitudes (i)

Characteristics of cosmic-ray hadronic interactions in the 1015 - 1017 eV range are studied by observing a total of 429 cosmic-ray families of visible energy greater than 100 TeV found in emulsion chamber experiments at high mountain altitudes, Chacaltaya (5200 m above sea level) and the Pamirs (4300 m above sea level). Extensive comparisons were made with simulated families based on models so far proposed, concentrating on the relation between the observed family flux and the behaviour of high-energy showers in the families, hadronic and electromagnetic components. It is concluded that there must be global change in characteristics of hadronic interactions at around 1016 eV deviating from thise known in the accelerator energy range, specially in the forwardmost angular region of the collision. A detailed study of a new shower phenomenon of small-pT particle emissions, pT being of the order of 10 MeV/c, is carried out and its relation to the origin of huge "halo" phenomena associated with extremely high energy families is discussed as one of the possibilities. General characteristics of such super-families are surveyed. © 1992.3702365431Borisov, (1981) Nucl.

The role of the district pediatrician in the early diagnosis of speech developmental disorders in preschool children

Speech and language are the most important means of communication between a child and the outer world. Currently in the Russian Federation there is no reliable data on the prevalence of speech and language disorders in children. According to foreign authors, speech disorders are diagnosed in 3,4–6,4% in the population of preschool children, and language disorders are diagnosed in 8–10% of cases. Early identification of the causes of speech and language development disorders in children is a complex interdisciplinary problem. The authors have developed an algorithm for diagnosing speech and language developmental disorders in preschool children, where the district pediatrician plays the leading role. It is district pediatrician who can assess the speed of the child’s speech skills development, based on age norms, analyze the history data, risk factors, carry out a physical examination of the child, develop an individual program for conducting basic laboratory and instrumental studies and consult specialists. Dynamic observation of this category of children is important
