Background. Since severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) first emerged, many articles have been published on airway management for coronavirus disease 2019 (COVID-19) patients. However, there is a lack of clear and concise conceptual framework for working with infected patients without respiratory failure undergoing general anaesthesia compared to noninfected patients. The aim of this article is to review current literature data on new challenges for anaesthesia providers, compare standard airway management techniques protocols with new data, and discuss optimisation potential.Materials and methods. Literature search was performed in Google Scholar and PubMed databases using these keywords and their combinations: anaesthesia, preoxygenation, airway management, difficult airway, SARS-CoV-2, COVID-19. The following nonsystematic review is based on a comprehensive literature search of available data, wherein 41 articles were chosen for detailed analysis. Summarised and analysed data are presented in the article.Results. SARS-CoV-2 has unique implications for airway management techniques in patients without respiratory failure undergoing general anesthesia. Main differences with the standard practice include: institutional preparedness, team composition principles, necessary skills, equipment, drugs, intubation and extubation strategies. Failed or difficult intubation is managed with predominance of emergency front of neck access (FONA) due to increased aerosol generation.Conclusions. Airway management techniques in COVID-19 patients without respiratory failure are more challenging than in noninfected patients undergoing general anaesthesia. Safe, accurate and swift actions avoid unnecessary time delay ensuring the best care for patients, and reduce risk of contamination for staff. Appropriate airway strategy, communication, minimisation of time for aerosol generating procedures and ramped-up position aid to achieve these goals. During the pandemic, updated available literature data may change clinical practice as new evidence emerges.

Published: February 2021

In this paper, we present models for the analysis of the behavior of the virtual library (VL) users. Unlike the models presented in the literature, they use only the big data that is stored in the log files of virtual library servers and methods of statistics, association rules, and recommendation systems. The proposed models were implemented with R software. Using the proposed models, the analysis of the behavior of VL users of Lithuanian research and study of higher education institutions was performed for the first time. The results showed that the proposed models allow to operatively analyze the behavior of virtual library users using advanced search filters, facets, and provide suggestions for improvement of service quality.

During 2009–2011, 50 points of the Daube River Basin were surveyed. In 23 of them, seven species of Unionidae were recorded: U. pictorum, U. tumidus, U. crassus sensu lato, A. anatina, A. cygnea, P. сomplanatа and S. woodiana, which is an invasive species. Th e index of occurrence of freshwater mussels in general was 100 % in the Lower Danube River (5 study areas), 42 % in Tisa River (31 study areas), 33.3 % in Seret River (3 study areas), 36 % in Prut River (11 study areas). Th e index of occurrence of species was rather low: 24 % of A. anatina, 22 % of U. tumidus, 22 % of U. crassus, 16 % of U. pictorum, 14 % of P. complanata, 14 % of S. woodiana, and 2 % of A. cygnea. U. crassus was not found in the Lower Danube river, while A. cygnea was found only there outside the main watercourse. Th e invasive species S. woodiana occurred in the Lower Danube River and in the sub-basin of Tisa River (with 83 % and 20 % frequency, respectively. Th e mean values of population densities ranged from 1.00 (A. cygnea) to 6.14 ind./m2 (S. woodiana), and the mean biomass varied from 1.14 (P. сomplanatа) to 797.54 g/m2 (S. woodiana).

Published: February 2021

Background. In recent years, great importance has been given to preserving and strengthening the health of the population, the role of disease prevention and formation of a healthy lifestyle, including the formation of a culture of healthy nutrition of the population. With the aim to study changes in nutrition of the Russian population over the past 100 years, we have conducted a nutrition assessment based on statistical data. The results obtained indicate significant changes in the quantitative composition of the main groups of products consumed by the population of Russia. The structure of the diet indicates significant deviations from the recommendations on rational food consumption standards that meet modern requirements for a healthy diet. There is a lack of consumption of potatoes, vegetables, fruits, milk and dairy products, eggs, which are a source of essential nutrients for the body proteins, dietary fiber, vitamins, minerals. At the same time, over the past hundred years, there has been a significant, even excessive, increase in the consumption of meat products and sugar.
Conclusion. Good nutrition largely determines the quality of life and health indicators of the nation.

Changing roles of religiosity and patriarchy in women's employment in different religions in Europe between 2004 and 2016
Authors: Guveli Ayse , Spierings Niels 
Published: February 2021

Objective: This paper seeks to understand the changing roles of religiosity and gender attitudes in the employment of women in Europe between 2004 and 2016.
Background: Religiosity and gender traditionalism are both considered to decrease the likelihood of women’s employment. This study argues that this relationship needs to be decoupled, as religiosity and gender traditionalism have different underlying mechanisms.
Method: We analysed rounds 2 (2004), 4 (2008), 8 (2010), and 10 (2016) of the European Social Survey (ESS), which include, among other data, information on employment, religious affiliation, religiosity, and gender role attitudes in 16 countries (N=39,233).
Results: We show that taking religiosity into account further increases the already increased likelihood of employment for Catholic, Protestant, and Jewish women compared to women with no religion. We also find, however, that religiosity decreases the employment gap between Muslim and Orthodox women on the one hand and secular women on the other. Including gender role attitudes in the model only marginally explains the employment gap.
Conclusion: Our findings support the idea that the mechanisms that underlie the relationships religiosity and traditional gender role attitudes have with women's employment differ. Over time, the likelihood of employment increases for women of all religions, except for Muslim women, among whom it drops.

Liner Hanger Installation in Challenging Offshore Well Conditions
Authors: Luna David , Elizalde Roberto , Diwaku Wantuadi 
Published: February 2021

ABSTRACT
ERD wells are commonly associated with major challenges for installation of casing and liner strings. These wells typically present high torque and drag parameters that jeopardize getting strings to total depth.
In an attempt to optimize production, a major oil company in Angola decided to re-enter the study well in early 2016. A sidetrack was opened in the 9 5/8-in. casing, and drilling continued in the 8 ½-in. hole and penetrated the target zone in the highest location. Then a 7-in. production liner was run.
To reach the target zone, 5,583 ft of 8 ½-in. hole was drilled and deviations varied from 45° to 87°. This trajectory was a challenge for subsequent running of 7-in. liner. Torque and drag (T&D) models showed liner rotation at total depth (TD) was not possible, and a surge model indicated likelihood of mud losses while running the liner.
Liner hanger technologies became a very important phase of well construction, and service companies developed advanced liner hangers to overcome hostile well environments. In this case study, the short time available from the planning to execution phases and the current oil market conditions made it imperative that the right equipment, service, and technology were available in country. To achieve the ideal working parameters and get the liner to bottom, a thorough assessment needed to be performed to ensure risk mitigation.
This paper presents summarizes steps considered during planning for the 7-in. liner run including a detailed engineering analysis that enabled the operator to make the best decisions based on the available resources. The paper will also discuss lessons learned and best practices captured during the job that will be used for subsequent liners in similar wells.
Petroleum Potential of Rift Basins in Northern Somalia – A Fresh Look
Authors: Witte Jan , Trümpy Daniel , Meßner Jürgen , Babies Hans Georg 
Published: February 2021

ABSTRACT
Several wells have encountered good oil shows in the rift basins of northern Somalia, however, without finding commercial hydrocarbons to date. It is widely accepted that these basins have a similar tectonic evolution and a comparable sedimentary fill as the highly productive rift basins in Yemen from which they have been separated by the opening of the Gulf of Aden (fully established in Mid Oligocene). We present new regional tectonic maps, new basement outcrop maps, a new structural transect and new play maps, specifically for the Odewayne, Nogal, Daroor and Socotra Basins.
Digital terrain data, satellite images, surface geology maps (varying scales), oil seep/slick maps, potential data (gravity), well data from ~50 wells and data from scientific publications were compiled into a regional GIS-database, so that different data categories could be spatially analyzed.
To set the tectonic framework, the outlines of the basins under investigation were re-mapped, paying particular attention to crystalline basement outcrops. A set of play maps was established. We recognize at least three source rocks, five reservoirs and at least three regional seals to be present in the area (not all continuously present). Numerous oil seeps are documented, particularly in the Nogal and Odewayne Basins, indicative of ongoing migration or re-migration. Data from exploration wells seem to further support the presence of active petroleum systems, especially in the central Nogal, western Nogal and central Daroor Basins.
Our GIS-based data integration confirms that significant hydrocarbon potential remains in the established rift basins, such as the Nogal and Daroor Basins. Additionally, there are a number of less known satellite basins (on and offshore) which can be mapped out and that remain completely undrilled. All of these basins have to be considered frontier basins, due to their poorly understood geology, remoteness, marketing issues and missing oil infrastructure, making the economic risks significant. However, we believe that through acquisition of new seismic data, geochemical analysis, basin modelling and, ultimately, exploration drilling these risks can be mitigated to a point where the economic risks become acceptable.
We encourage explorers to conduct regional basin analysis, data integration, a GIS-based approach and modern structural geology concepts to tackle key issues, such as trap architecture, structural timing, migration pathways and breaching risks.
Source Rocks of Somalia – A Regional Assessment
Authors: Trümpy Daniel , Witte Jan , Weber Immanuel , Da Ponte Souza João P. 
Published: February 2021

ABSTRACT
In total, some 60 wells have been drilled onshore and less than 10 offshore Somalia*, none of which in deep water. Several prospective basins remain undrilled, such as the offshore Jubba and Mid Somali High basins and the onshore Odewayne basin. In view of the gas discoveries offshore Mozambique and Tanzania, and also of encouraging results offshore Kenya (sub-commercial oil discovery Sunbird-1) and in Madagascar, the Somalian offshore and onshore basins were re-evaluated.
As to the Somali onshore basins, the extension of the Yemeni Jurassic and Cretaceous rifts into Somalia highlights their prospectivity. Seeps abound (Odewayne and Nogal basins) and some wells encountered good shows. Late Jurassic and Upper Cretaceous marine shales are source rock candidates. Gas in the area of Mogadishu may be associated with the Early Triassic Bokh Fm. source rock. Seeps in western Somalia are rare, and may result either from long-distance migration out of the Calub Graben or from locally mature Lower Cretaceous or Upper Jurassic.
We establish an inventory of proven and possible source rock occurences in Somalia by integrating publicly available data on slicks and seeps, geological and gravity maps, literature data, well data and geological information from adjoining basins. Our data indicate that in the Somali part of the Gulf of Aden, high heat-flow may critically affect the Late Jurassic source rock. However, Late Cretaceous or even Eocene sources may be locally oil-mature.
The presence of source rocks on the Somali Indian Ocean margin remains presently speculative. Abundance of slicks in the area south of Mogadishu may not relate to hydrocarbons. Of more interest are reported isolated slicks further to the north, in deeper waters of the Mogadishu and Mid-Somalia High Basins. These slicks may be related to Lower/Mid-Jurassic, Late Jurassic, Late Cretaceous or Eocene sources.
Analysis of onshore seeps in northern Somalia (Nogal, Daroor, Odewayne basins), integrated with seismic data, will allow to determine the origin of these oils and an assessment of the size of prospective kitchen areas. In the offshore, 3D-Basin-modelling will be required to determine which areas are prospective for gas or, especially, for oil.
Lessons Learned: How to Produce More Hydrocarbons from Blowout Wells
Authors: Tang Xueqing , Dou Lirong , Wang Ruifeng 
Published: February 2021

ABSTRACTDeep formation damage caused by killing fluid frequently occurs in blowout wells and clean-up operations may result in early water breakthrough and less hydrocarbon recovery. This paper presents three innovative practices applied in oil and gas wells that suffered blowout accidents for more hydrocarbon recovery. i.e.: For a blowout oil well, N2 huff and puff process can be applied for clean-up around the wellbore. During the first several cycles, the well got clean-up and output and wellhead pressure increased.For a blowout gas well in a massive gas pool, controllable drawdown pressure is recommended due to its updip location. The drawdown pressure should be met for both clean-up and minimum water coning. When water breakthrough appears, then neighboring wells at lower locations produce at larger drawdown pressure than that of blown-out well to minimize the impact of water influx on production of blowout well.For a blowout gas well in a faulted, naturally fractured reservoir, drawdown pressure should be maintained at the level of no liquid-loading in the wellbore. Gas and water co-production should be kept stable. Any shut-in of the well must be avoided.These methods have been successfully utilized in more than 40 wells for over 50 years. The three typical field examples are illustrated. One of them is an oil well in sandstone reservoir, with double oil rate as the nearby wells. The rest are a gas well in massive carbonate pool with bottom water, with the most prolific gas production in the field, and a gas well in a naturally fractured reservoir, with Gp of over 180 BCF.
A Dual-Model of Posttraumatic Stress and Posttraumatic Growth in a Community Sample of Female Conflict-Related Sexual Violence Survivors from Bosnia &amp; Herzegovina
Authors: Anderson Kimberley , Komproe Ivan , Delić Amra , Avdibegović Esmina , Ee Elisa van , Glaesmer Heide 
Published: February 2021

Abstract
Background Posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) are increasingly acknowledged as psychological outcomes that can co-occur in the aftermath of a traumatic event. Less clear however, is how these outcomes interact – particularly for female survivors of conflict-related sexual violence (CRSV) – and to what extent intermediary factors such as coping play a role in this relationship.Methods In a sample of 192 survivors of the 1990s conflict in Bosnia & Herzegovina; of whom 104 experienced CRSV, and 88 who did not, a structural equation model was tested using LISREL 8.8 that included CRSV as a traumatic event, ‘positive reinterpretation’ (as a strategy of approach coping) and ‘behavioural disengagement’ (as a strategy of avoidance coping), and PTSD and PTG as psychosocial outcomes. It was hypothesised that there would be differences in the mechanisms by which PTG and PTSD interact in the two subgroups, given the differences in the nature of the trauma they experienced.Results Through multiple indirect relationships, results showed that CRSV survivors respond to their trauma with both PTSD and PTG, substantiating a dual PTSD-PTG mechanism, as opposed to a single spectrum with these outcomes at the poles. With regard to coping strategies, positive reinterpretation predicted greater PTG, and behavioural disengagement predicted greater PTSD. In the sample of non-sexual violence survivors, positive reinterpretation also remained a significant predictor of PTG.Conclusions Findings suggest that positive reinterpretation as a coping strategy appears to be a stable characteristic that independently predicts PTG, irrespective of trauma type. Mental health care professionals should take into account this specific mechanism when addressing the needs of CRSV survivors, but also war survivors more generally. Reframing traumatic events and post-trauma sequalae during treatment could lead to greater PTG and enhance recovery.
Significantly decreased islet β cell function and increased fasting plasma glucose in patients with chronic hepatitis B: a cross-sectional study

Published: February 2021

Abstract
Background: The contributing factors of abnormal glucose metabolism and the characteristics of the homeostasis model assessment of β cell function (HOMA-β) value in chronic hepatitis B (CHB) patients are unclear and worth studying.Method: This cross-sectional study recruited 110 CHB patients (CHB group) and 110 patients without hepatitis B virus (non-HBV group); the groups were matched according to sex, age, and body mass index. The contributing factors of abnormal glucose metabolism and the characteristics and differences in glucose metabolism parameters between the two groups were analyzed. Results: The abnormal glucose metabolism rate was higher in CHB patients with liver cirrhosis (LC) and patients with hepatitis B envelope antigen (HBeAg) (-) status. In addition, under the same glucose metabolism conditions, the fasting plasma glucose (FPG) levels of the CHB group was higher than that of the non-HBV group, especially in those with LC that had higher FPG levels (all p=0.000), while the HOMA-β values was significantly lower in the CHB group than in the non-HBV group, especially under normal glucose tolerance conditions (all p=0.000). Further analyses revealed that the main contributing factors of abnormal glucose metabolism were HBeAg (-) status and hepatitis B envelope antibody levels, but HBV serological and virological indicators had no direct effect on the HOMA-β value.Conclusion: These findings provide a reference that will allow clinicians to monitor abnormal glucose metabolism in CHB patients, especially those with LC or HBeAg (-) status, focus on the protection of islet β-cell function, and avoid the application of insulin secretagogues in CHB patients with abnormal glucose metabolism.
