Западное структурное замыкание Припятско-Днепровско-Донецкого авлакогена
In segmented paleorift systems such as the Pripyat–Dnieper–Donetsk aulacogen, which penetrate deep into the continent from the side of the paleoocean margin and most often close here, each segment represents an autonomous structure of the lithosphere. The presented article shows that the tectonic position of the Pripyat paleorift as the western closing segment of the indicated aulacogen was due to a change in the intensity of syn-rift and plate-tectonic processes in the extended rift system from east to west. In the band of the Paleoproterozoic Fenno-Sarmatian collision, the Central Belarusian suture zone of the Central Russian transpression belt isolated by S. V. Bogdanova in 2018 was a blocking transverse barrier to relative development of Hercynian synrift processes in the western direction.В сегментированных палеорифтовых системах типа Припятско-Днепровско-Донецкого авлакогена, которые проникают со стороны палеоокеанической окраины в глубь континента и здесь чаще всего замыкаются, каждый сегмент представляет собой автономную структуру литосферы. В представленном сообщении показано, что тектоническая позиция Припятского палеорифта как западного замыкающего сегмента указанного авлакогена была обусловлена изменением интенсивности синрифтовых и плейт-тектонических процессов в протяженной рифтовой системе с востока на запад. В полосе палеопротерозойской Фенносарматской коллизии Центрально-Белорусская шовная зона обособленного С. В. Богдановой в 2019 г. Центрально-Русского транспрессионного пояса явилась блокирующей поперечной преградой относительно развития герцинских синрифтовых процессов в западном направлении
Тектонические особенности разнотипных нефтегазоносных бассейнов запада Восточно-Европейской платформы
In the Neoproterozoic and Paleozoic, different-type sedimentary basins, some of which are oil-and-gas bearing, were formed in the western East European Platform (EEP). These basins are confined to two types of regional structures – rift intracontinental and passive-coastal. Their tectonic features determined the geological conditions of oil and gas formation and oil and gas accumulation. The Pripyat paleorift oil and gas bearing basin, which is the closing western segment of the Hercynian Pripyat-Dneprov-Donetsk avalacogenes, has the largest hydrocarbon reserves in the region and a complex structure. High density of block and plicate-block divisions of oil-and-gas bearing complexes is connected with syngenetic faults and salt tectonics. The oil-and-gas content of the sedimentary basins of the Caledonian passive margin of the West WEP – Baltica, Podlaska-Brest, Lublin, Volyn-Podolsk, is caused by the extended areal of the oil-and-gas formation in the sub- and near-thrust deep-submerged sedimentary complexes in the Teisser-Tornquist zone. It was the main source of hydrocarbon-fluid migration eastward into the sedimentary basins of the WEP passive margin.В неопротерозое и палеозое на западе Восточно-Европейской платформы (ВЕП) сформировались разнотипные осадочные бассейны, часть которых нефтегазоносные. Эти бассейны приурочены к двум типам региональных структур – рифтовому внутриконтинентальному и пассивно-окраинному. Их тектонические особенности определяли геологические условия нефтегазообразования и нефтегазонакопления. Припятский палеорифтовый нефтегазоносный бассейн, являющийся замыкающим западным сегментом герцинского Припятско-ДнепровскоДонецкого авлакогена, обладает наиболее крупными в этом регионе запасами углеводородного сырья и сложным строением. Высокая плотность блоковой и пликативно-блоковой делимости нефтегазоносных комплексов связана с синрифтовыми разломами и соляной тектоникой. Нефтегазоносность осадочных бассейнов каледонской пассивной окраины запада ВЕП – Балтийского, Подлясско-Брестского, Люблинского, Волыно-Подольского обусловлена протяженным ареалом нефтегазообразования в под- и близнадвиговых глубокопогруженных осадочных комплексах в зоне Тейссейра–Торнквиста. Он был основным источником миграции УВ-флюидов на восток в осадочные бассейны пассивной окраины ВЕП
Системные исследования приоритетных геологических объектов в Припятском прогибе с целью увеличения углеводородного ресурсного потенциала
A new direction of system research in the Pripyat Trough to increase the hydrocarbon resource potential of the bowels on the basis of modern geological and geophysical technologies has been justified. Two-type priority objects, which are oil and gas prospecting and research polygons, are distinguished. The first-type object is represented by large oil multifield and prohibitive structures in the highly promising areas and sections. The second-type object includes the structures of the western part of the Central Zone of the Pripyat Trough where a rather high level of direct oil and gas occurrences is established.Обосновано новое направление системных исследований в Припятском прогибе с целью увеличения углеводородного ресурсного потенциала недр на основе современных геолого-геофизических технологий. Выделены два типа приоритетных объектов, которые представляют собой нефтегазопоисковые и исследовательские полигоны. Первый тип представлен крупными нефтяными многозалежными месторождениями и сопредельными структурами на высокоперспективных участках и разрезах. Второй тип включает структуры западной части Центральной зоны Припятского прогиба, где установлен достаточно высокий уровень прямых нефтегазопроявлений
Physical and mental health impact of COVID-19 on children, adolescents, and their families: The Collaborative Outcomes study on Health and Functioning during Infection Times - Children and Adolescents (COH-FIT-C&A)
Background: The COVID-19 pandemic has altered daily routines and family functioning, led to closing schools, and dramatically limited social interactions worldwide. Measuring its impact on mental health of vulnerable children and adolescents is crucial. Methods: The Collaborative Outcomes study on Health and Functioning during Infection Times (COH-FIT – www.coh-fit.com) is an on-line anonymous survey, available in 30 languages, involving >230 investigators from 49 countries supported by national/international professional associations. COH-FIT has thee waves (until the pandemic is declared over by the WHO, and 6–18 months plus 24–36 months after its end). In addition to adults, COH-FIT also includes adolescents (age 14–17 years), and children (age 6–13 years), recruited via non-probability/snowball and representative sampling and assessed via self-rating and parental rating. Non-modifiable/modifiable risk factors/treatment targets to inform prevention/intervention programs to promote health and prevent mental and physical illness in children and adolescents will be generated by COH-FIT. Co-primary outcomes are changes in well-being (WHO-5) and a composite psychopathology P-Score. Multiple behavioral, family, coping strategy and service utilization factors are also assessed, including functioning and quality of life. Results: Up to June 2021, over 13,000 children and adolescents from 59 countries have participated in the COH-FIT project, with representative samples from eleven countries. Limitations: Cross-sectional and anonymous design. Conclusions: Evidence generated by COH-FIT will provide an international estimate of the COVID-19 effect on children's, adolescents’ and families’, mental and physical health, well-being, functioning and quality of life, informing the formulation of present and future evidence-based interventions and policies to minimize adverse effects of the present and future pandemics on youth
The collaborative outcomes study on health and functioning during infection times in adults (COH-FIT-Adults): Design and methods of an international online survey targeting physical and mental health effects of the COVID-19 pandemic
Background:. High-quality comprehensive data on short-/long-term physical/mental health effects of the COVID-19 pandemic are needed. Methods:. The Collaborative Outcomes study on Health and Functioning during Infection Times (COH-FIT) is an international, multi-language (n=30) project involving >230 investigators from 49 countries/territories/regions, endorsed by national/international professional associations. COH-FIT is a multi-wave, on-line anonymous, cross-sectional survey [wave 1: 04/2020 until the end of the pandemic, 12 months waves 2/3 starting 6/24 months threreafter] for adults, adolescents (14-17), and children (6-13), utilizing non-probability/snowball and representative sampling. COH-FIT aims to identify non-modifiable/modifiable risk factors/treatment targets to inform prevention/intervention programs to improve social/health outcomes in the general population/vulnerable subgrous during/after COVID-19. In adults, co-primary outcomes are change from pre-COVID-19 to intra-COVID-19 in well-being (WHO-5) and a composite psychopathology P-Score. Key secondary outcomes are a P-extended score, global mental and physical health. Secondary outcomes include health-service utilization/functioning, treatment adherence, functioning, symptoms/behaviors/emotions, substance use, violence, among others. Results:. Starting 04/26/2020, up to 14/07/2021 >151,000 people from 155 countries/territories/regions and six continents have participated. Representative samples of ≥1,000 adults have been collected in 15 countries. Overall, 43.0% had prior physical disorders, 16.3% had prior mental disorders, 26.5% were health care workers, 8.2% were aged ≥65 years, 19.3% were exposed to someone infected with COVID-19, 76.1% had been in quarantine, and 2.1% had been COVID 19-positive. Limitations:. Cross-sectional survey, preponderance of non-representative participants. Conclusions:. Results from COH-FIT will comprehensively quantify the impact of COVID-19, seeking to identify high-risk groups in need for acute and long-term intervention, and inform evidence-based health policies/strategies during this/future pandemics
Validation of the Collaborative Outcomes study on Health and Functioning during Infection Times (COH-FIT) questionnaire for adults
Background: The Collaborative Outcome study on Health and Functioning during Infection Times (COH-FIT; www.coh-fit.com) is an anonymous and global online survey measuring health and functioning during the COVID-19 pandemic. The aim of this study was to test concurrently the validity of COH-FIT items and the internal validity of the co-primary outcome, a composite psychopathology “P-score”. Methods: The COH-FIT survey has been translated into 30 languages (two blind forward-translations, consensus, one independent English back-translation, final harmonization). To measure mental health, 1–4 items (“COH-FIT items”) were extracted from validated questionnaires (e.g. Patient Health Questionnaire 9). COH-FIT items measured anxiety, depressive, post-traumatic, obsessive-compulsive, bipolar and psychotic symptoms, as well as stress, sleep and concentration. COH-FIT Items which correlated r ≥ 0.5 with validated companion questionnaires, were initially retained. A P-score factor structure was then identified from these items using exploratory factor analysis (EFA) and confirmatory factor analyses (CFA) on data split into training and validation sets. Consistency of results across languages, gender and age was assessed. Results: From >150,000 adult responses by May 6th, 2022, a subset of 22,456 completed both COH-FIT items and validated questionnaires. Concurrent validity was consistently demonstrated across different languages for COH-FIT items. CFA confirmed EFA results of five first-order factors (anxiety, depression, post-traumatic, psychotic, psychophysiologic symptoms) and revealed a single second-order factor P-score, with high internal reliability (ω = 0.95). Factor structure was consistent across age and sex. Conclusions: COH-FIT is a valid instrument to globally measure mental health during infection times. The P-score is a valid measure of multidimensional mental health
