No full textEfecto de dos modelos de periodización, el modelo clásico de Matveyev modificado y el modelo acumulación, transformación y realización, en el desplazamiento de la curva de lactato hacia la derecha en los nadadores juveniles a y b del Club Orcas de Tuluá
No full textilustraciones, gráficos, tablasLa presente investigación de enfoque cuantitativo, diseño cuasi-experimental de pre-prueba y pos-prueba con dos grupos experimentales, de alcance explicativo, determinó el efecto de dos modelos de periodización, el modelo clásico de Matveyev modificado, estructurado en un macrociclo de 24 semanas y el modelo de periodización ATR estructurado en dos macrociclos, uno de 13 semanas y otro de 11 semanas, en el que se comparó y analizó el desplazamiento de la curva de lactato hacia la derecha en los nadadores de la categoría juvenil A y B del club Orcas Tuluá, distribuidos en dos grupos de estudio, el grupo Matveyev con cinco participantes de una edad de 16.00 ± .54 años, una talla de 1.65 ± .126 centímetros y un peso de 55.00 ± 8.56 kg, y el grupo ATR con otros cinco nadadores jóvenes de 16.00 ± .44 años, de una estatura de 1.73 ± .05 centímetros y un peso de 58.00 ± 4.28 kg. Presentando como resultados más destacados, el aumento estadísticamente significativo de las velocidades de nado en el área funcional ritmo de competencia (RC) en el grupo Matveyev (p < .05) y cuanto al grupo ATR diferencias significativas en las velocidades de nado de las áreas funcionales subaeróbica (RI) y superaeróbica (RII) (p < .05), concluyendo que en los modelos de periodización clásico de Matveyev modificado y el modelo de periodización ATR, no evidenciaron diferencias significativas en el desplazamiento de la curva de lactato, rechazando así la hipótesis de investigación.Licenciado (a) en Educación Física, Recreación y DeportePregrad

A.V. Matveyev, V.E. Bordon, L.A. Nechiporenko. Technogenic Contamination of Cover Deposits along Automobile Roads in Belarus
No full textПо данным приближенно-количественного спектрального анализа образцов, отображенных на 19 ключевых участках, установлено загрязнение покровных отложений в придорожных полосах Zr, Pb, Mn, Cu, Ti, Ni, Cr, V, изредка Ba, P, B. Максимальная концентрация элементов-контаминантов при-урочена к полосе 40–80 м от полотна дороги. Распределение техногенных примесей довольно неравно-мерное, зависит от интенсивности движения автотранспорта и ряда других причин, на локальных участ-ках содержание элементов может превышать ПДК
Place Names of the Pelym River Area on Antal Reguly’s Handwritten Maps and the Etymologization of Mansi Toponyms
No full textThe article analyses toponymic data from the handwritten maps made in 1844–1845 by the outstanding Hungarian ethnographer and explorer Antal Reguly, that he later used as a basis for his famous Ethhnographic Map of the Northern Ural (1846). Reguly’s handwritten maps, still understudied, contain valuable toponymic information, considerably more detailed than in the final map, which makes them an important source of unique data on the toponymy of the region’s peoples in the 19th century. Based on previous research in the Pelym River toponymy (works by G. P. Vuono, G. V. Glinskikh, A. K. Matveyev), the materials of the explorations of G. F. Müller (1742), B. Munkácsi (1888–1889) and A. Kannisto (1901–1906), the fieldwork materials of the Ural University Toponymic Expedition, collected in 1960s–1970s, as well as on contemporary maps of the region, the author provides etymological interpretations of several toponyms of the Pelym River area whose Mansi population became completely Russified by the mid-20th century. The data retrieved from Antal Reguly’s maps serve to confirm the reliablity of previously suggested etymologies, to specify some of them, and to reconstruct the names that earlier failed to be etymologised

Several clinical studies of efficacy of treatment with sorafenib both in mono-regimen and combined with other drugs are discussed.
Reflectance of radon anomalies in magnetic field and tectonic elements of Belarus
No full textRegularities connecting radon anomalies in soil air of cover deposits of different genesis with magnetic anomalies and tectonic elements of Belarus have been indirectly determined through genetic types of Quaternary deposits. It is noted that the intensity of radon anomalies increases with transition to the tectonic structures subjected to multi-step processes of activation. Linearly stretched radon anomalies correlate with the deep faults of lithosphere
Impairments in Gas Exchange and Mechanical Properties of the Lung in Acute Cerebral Circulatory Disorders
No full textObjective: to study impairments in gas exchange and mechanical properties of the lung in relation to the pattern of a brain lesion in acute cerebral circulatory disorders (ACCD). Subjects and methods. Gas exchange (oxygenation index (PaO2/FiO2) and the degree of intrapulmonary blood shunting (Qs/Qt)), the mechanical properties of the lung (mean airway pressure (Р^^), airway resistance (Raw), static thoracopulmonary compliance (Cltst)), intracranial pressure (ICP) were studied and brain spiral computed tomography (SCT) was conducted on days 1, 3, 5, and 7 of the acute phase of ACCD in 18 patients. Results. Pmean increased in both groups on days 3 to 7, rose from day 5 in the presence of hemorrhagic stroke. Cltst was decreased and Raw was increased. From day 3 of hemorrhagic stroke, Cltst significantly became lower and Raw was higher. PaO2/FiO2 decreased from day 5, more in hemorrhagic stroke and Qs/Qt increased. ICP persisted in the upper normal range in ischemic stroke and rose up to 27.5±2.7 mm Hg in hemorrhagic stroke. A strong inverse correlation was found between ICP and PaO2/FiO2. SCT revealed dislocation in 13 patients. Conclusion. Gas exchange and the mechanical properties of the lung are impaired in acute cerebral circulatory disorders. The causes of this are multiple, but one of them is dysfunction of the stem structures of the brain due to its dislocation in the presence of high intracranial pressure. In hemorrhagic stroke, the impairments in gas exchange and mechanical properties of the lung are more marked and develop earlier than in ischemic stroke. Key words: acute cerebral circulatory disorder, respiratory failure, gas exchange, mechanical properties of the lung, intracranial pressure
