Human capital as a base for regional development : a case study

Purpose: The main aim of this article is to consider the main trends observed in the labor market in the regional agricultural sector. Design/Methodology/Approach: The study uses the statistical method, the method of analogy and comparison, as well as the positive and normative approach. Findings: The study indicated that in the agricultural sector there are several problems associated with the formation of human resources. This is evidenced by the presence of negative trends that have been observed over the past 20 years. The main problems are the low educational level of workers, aging professional staff, and a reduction in the number of employees in all positions. Practical implications: The socio-economic problems considered in the article indicate the urgent need to develop a mechanism of state support for agricultural workers. Originality/Value: The authors define the concept of human capital and reveal the essence of the factors influencing its formation, revealing them from the perspective of the socio-economic development of the region.peer-reviewe

CLINICAL AND MORPHOLOGICAL PARRALLELS IN THE COURSE OF RESPIRATORY SARCOIDOSIS

Sarcoidosis is a systemic disease characterized by the development of chronic immune inflammation and formation of granulomas. It is important to know clinical, morphological and immunologic variants of the course of this disease in order to investigate the pathomorphologic parameters of the granuloma.Of late negative trends have been observed in the changes of sarcoidosis pathomorphology. Due to the above it is important to investigate predictors for the course of this disease, including specific parameters of granulematous inflammatory process in various clinical variants not only from the point of view of diagnostics but further management tactics for those suffering from this disease

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum

Характеристика макро- и микроэлементного состава медиастинальных лимфатических узлов, пораженных саркоидозом

This study was aimed at measuring concentrations and investigation of relationships between macro- and microelements in mediastinal lymph nodes of patients with sarcoidosis. Methods. The study involved 28 patients (50% were males; median age, 42.5 (23; 53) years) with confirmed diagnosis of sarcoidosis. Autopsy samples from 13 individuals died from occasional causes (41.2% were males; median age, 43 (38.7; 61.3) years) were used for comparison. The groups did not differ in age and gender. Neutron activation analysis was used to investigate chemical elements in mediastinal lymph node tissue samples. Results. Concentrations of Ca, Cr, Fe, Co, Zn, Rb, Sb, Cs, Ba, Eu, Lu, Yb, Hf, Th, and U in the lymph node tissue of patients with sarcoidosis were increased, and concentration of zinc was decreased compared to control samples. Concentrations of Sm, Au, Sr, Nd, As, Br, Ag, Tb, Sc, Ta, Na, and La did not differ between the groups. Direct relationships were found in element groups Fe-Cr-Sb-Ca, Fe-U-Th, Co-U-Th, U-Cr, Th-Br, Sc-Zn, Eu-La, and Ce-Lu.Актуальность изучения саркоидоза связана с увеличением распространенности указанного заболевания. Материалы и методы. В исследование были включены пациенты (n = 28: 14 (50 %) мужчин, 14 (50 %) женщин; медиана возраста – 42,5 (25; 53) года) с верифицированным саркоидозом. Образцы для группы сравнения были взяты от людей, умерших от случайных причин (n = 13: 8 (41,2 %) мужчин, 5 (38,7 %) женщин; медиана возраста – 43 (38,7; 61,3) года). Группы статистически не различались по полу и возрасту. При нейтронно-активационном анализе в ткани медиастинальных лимфатических узлов (ЛУ) у пациентов с верифицированным саркоидозом (n = 28) определен ряд химических элементов. Результаты. Установлено повышенное содержание Ca, Cr, Fe, Co, Zn, Rb, Sb, Cs, Ba, Eu, Lu, Yb, Hf, Th, U, низкое содержание Zn по сравнению с контрольными образцами. Достоверных различий по содержанию Sm, Au, Sr, Nd, As, Br, Ag, Tb, Sc, Ta, Na, La не выявлено. Установлены положительные ассоциации в группах Fe-Cr-Sb-Ca, Fe-U-Th, Co-U-Th, U-Cr, Th-Br, Sc-Zn, Eu-La, Ce-Lu. Заключение. Выявленные особенности указывают на общий источник поступления элементов из окружающей среды. Для Fe, Са, Co возможно перераспределение из кровеносного русла с накоплением в ЛУ, что можно расценить как защитную реакцию организма на поступление химических элементов в виде гранулематозной реакции и последующей кальцификации
