Artificial illumination of the surface pedestrian crossings of highways of the city of Volgograd

The study of the levels of artificial illumination of ground pedestrian crossings of main roads of regulated traffic of the district significance of the city of Volgograd from the point of view of their safety for pedestrians in the dark was carried out. The article describes the methodology of this study, at the first stage of which graphic representation of roads with lighting devices located on them were drawn up and the distances between points and number of calculated points for measuring were determined. The second stage was used to measure the illumination levels of pedestrian crossings and the brightness of road surfaces. Further, on the basis of the obtained data, the average brightness and illumination, the overall uniformity of brightness and the overall uniformity of illumination of the road surface on both highways were calculated. The results are correlated with the norms defined by the State Standards. In the course of the work carried out, it was found out that the studied indicators of artificial illumination at these pedestrian crossings mainly meet the requirements of State Standarts.Проведено исследование уровней искусственной освещённости наземных пешеходных переходов магистральных дорог регулируемого движения районного значения города Волгограда с позиции их безопасности для пешеходов в тёмное время суток. В статье описана методика проведения данного исследования, на первом этапе которого были составлены графические схемы дорог с расположенными на них осветительными приборами и определены шаг и число расчётных точек для проведения замеров. Вторым этапом проведены измерения уровней освещённости пешеходных переходов и яркости дорожных покрытий. Далее на основании полученных данных были рассчитаны средние яркость и освещенность, общая равномерность яркости и общая равномерность освещённости дорожного покрытия на обеих автомобильных дорогах. Результаты соотнесены с нормами, определёнными Государственными Стандартами. В ходе проведённой работы выяснили, что исследуемые показатели искусственной освещённости на данных пешеходных переходах в основном соответствуют требованиям ГОС

The interdependence of external signs of connective tissue dysplasia and the formation of the female pelvis.

45 students of the Ural State Medical University were researched. The correlation of anthropometric indices and external signs of connective tissue dysplasia with the size of the female pelvis is estimated. They revealed smaller pelviometric indices for girls with low height, weight, length of hand and foot, and signs of joint hypermobility.Проведено исследование 45 студенток Уральского государственного медицинского университета. Оценена корреляция антропометрических показателей и внешних признаков дисплазии соединительной ткани с размерами женского таза. Выявили меньшие пельвиометрические показатели у девушек с низким ростом, весом, длиной кисти и стопы, признаками гипермобильности суставов

Проведено когортное поперечное исследование, включившее 128 беременных женщин, взятых методом сплошной выборки, на разных сроках гестации, среди которых выделена группа пациенток, получавших гестагенную поддержку. Определена частота назначения гестагенов и структура показаний к их применению во время беременности

Cause of Death and Predictors of All-Cause Mortality in Anticoagulated Patients With Nonvalvular Atrial Fibrillation : Data From ROCKET AF

M. Kaste on työryhmän ROCKET AF Steering Comm jäsen.Background-Atrial fibrillation is associated with higher mortality. Identification of causes of death and contemporary risk factors for all-cause mortality may guide interventions. Methods and Results-In the Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF) study, patients with nonvalvular atrial fibrillation were randomized to rivaroxaban or dose-adjusted warfarin. Cox proportional hazards regression with backward elimination identified factors at randomization that were independently associated with all-cause mortality in the 14 171 participants in the intention-to-treat population. The median age was 73 years, and the mean CHADS(2) score was 3.5. Over 1.9 years of median follow-up, 1214 (8.6%) patients died. Kaplan-Meier mortality rates were 4.2% at 1 year and 8.9% at 2 years. The majority of classified deaths (1081) were cardiovascular (72%), whereas only 6% were nonhemorrhagic stroke or systemic embolism. No significant difference in all-cause mortality was observed between the rivaroxaban and warfarin arms (P=0.15). Heart failure (hazard ratio 1.51, 95% CI 1.33-1.70, P= 75 years (hazard ratio 1.69, 95% CI 1.51-1.90, P Conclusions-In a large population of patients anticoagulated for nonvalvular atrial fibrillation, approximate to 7 in 10 deaths were cardiovascular, whereasPeer reviewe
