Abstract
Due to the discovery of new giant fields, the Russian Federation is actively shifting oil and gas production to northern regions and the Arctic shelf. However, harsh operating conditions, low temperatures, special environmental requirements, and limited infrastructure require new approaches to the full-scale development of the fields. Using gas hydrates as an alternative technology for storing and transporting natural/associated gases is becoming increasingly relevant. This technology has many advantages, such as environmental safety, relatively low temperatures and pressures for hydrate formation and storage, and high gas content in the hydrate form. Special attention is paid to developing efficient methods to produce the hydrates, on which the feasibility of the entire technological process depends. Several highly efficient reagents to accelerate hydrate formation were designed and successfully implemented in scientific and technical projects devoted to solidified natural gas technology. The hydrate issue also arises due to the need to create a controlled flow of hydrate particles in oil.
Homophily in Global Trade
Authors: Shi Ningyi 
Published: April 2024

Abstract

This paper investigates the presence of homophily in global trade. The prevalent theoretical intuition and justification for relevance of homophily is dissected into two distinct mechanisms: concord effect and nexus effect. Using post-COVID cross-sectional data from 2021, this paper empirically confirms the presence of homophily in global trade along language and (tertiary) education similarities. In other words, Two countries that are more similar in language and in (tertiary) education attainment tend to trade more. While concord and nexus effects can explain homophily along language similarities in global trade, they fall short for explaining homophily along education similarities. Additionally, religious similarities negatively impact global trade, and the reason for this observed damping effect of religion similarity is unaccounted by current literature. This paper also discovers two empirical associations - one positive between religious similarity, social connectedness, and regional trade agreement participation; one negative between educational similarity and social connectedness - both lacking theoretical backing. These findings highlight the need for further theoretical exploration to understand the nuanced impacts of these associations on global trade
Assessing the Impact of Nigerian Government Policies on Building Resilience and Facilitating Transformational Recovery: a Comparative Analysis With Other African Countries

Published: April 2024

Abstract

This study seeks to critically analyze the effectiveness of Nigerian government policies in building resilience and facilitating transformational recovery in the face of diverse crises, using a comparative approach with other African countries. With various challenges ranging from economic downturns, climate change effects, to public health emergencies, resilience has become an essential characteristic for Nigerian communities. The government's role in developing policies that foster resilience and transformational recovery is crucial in this context. The research employs the qualitative research design, including a policy analysis of Nigerian government strategies and interventions, and a comparative analysis with selected African countries that have shown significant strides in building resilience. The countries selected for comparison include Kenya, Rwanda, and South Africa, each with unique resilience-building policies despite confronting similar challenges as Nigeria. Preliminary findings suggest that effective government policies typically involve strong community engagement, a robust public health infrastructure, sustainable economic strategies, and comprehensive disaster risk management plans. The study aims to provide actionable recommendations for policy improvements in Nigeria based on the successful strategies employed by the other African countries under study. The study's implications extend beyond Nigeria, as it adds to the broader discourse on the role of government policies in building resilience and facilitating transformational recovery in developing countries, especially in the African context.

Published: April 2024

Abstract

Western Hoolock Gibbon (Hoolock hoolock) heavily rely on forests for their survival, as they are forest-dependent animals. In order to thrive, they require vast expanses of undisturbed forest. However, their natural habitat is facing severe threats due to activities such as logging, mining, and the expansion of agriculture. Furthermore, these remarkable creatures are also targeted by hunters for their meat and various body parts, which are unfortunately sought after for use in traditional medicine. This research examines the behavioural dynamics of the Western Hoolock Gibbon (Hoolock hoolock) at Hollongapar Gibbon Wildlife Sanctuary situated at Assam, India, providing critical insights into their social organization, feeding patterns, territorial behaviours, and reproductive strategies. Utilizing methodologies such as direct observations and photography over a year, the study highlights a complex social hierarchy and specialized vocal communication within gibbon groups. Seasonal shifts significantly influence their dietary preferences, which in turn affect their ranging patterns and habitat choices, underscoring the sanctuary’s ecological value for their sustenance. Key findings indicate a reliance on specific fruit-bearing trees and the impact of anthropogenic disturbances on their spatial distribution. These observations are instrumental for crafting targeted conservation strategies, stressing the importance of habitat conservation, continuous ecological monitoring, and local community engagement in conservation efforts. By offering a deeper understanding of behavioural ecology of Hoolock hoolock, this study lays the groundwork for informed conservation practices essential for the survival and well-being of this endangered species.

Published: April 2024

Abstract

The multi-agent reinforcement learning (MARL) problem is a well-known field of study that has been gaining special interest in the last decade. From cooperative to competitive learning, MARL systems are mainly validated in game-theoretical environments and real-time game engines due to the inherent system complexity. Given the robustness of Q-based methods under multi-agent frameworks proved in previous multi-agent studies, we present a real autonomous multi-drone system for warehousing that combines a double deep Q network (DDQN) for high-level control and a predictive potential field algorithm for dynamic obstacle avoidance. A linear quadratic regulator (LQR) is used for low-level vehicle dynamics. Our decentralized and generalized DDQN is trained in a virtual representation of our indoor flight arena. Both controllers are integrated and validated on a real heterogeneous fleet of 3 multirotor vehicles that need to pick up and deliver a series of assigned virtual payloads while coordinating static and dynamic collision avoidance. As compared to point-to-point (p2p) navigation, the implemented system demonstrates to be more robust and resilient against unexpected conditions. Further model training schemes and integration designs are proposed as future work to improve collective swarm behavior.

Abstract

This study commences by extracting hourly data on PM10 and PM2.5 concentrations to discern occurrences of sand and dust events in the North China region spanning from 2015 to 2023. Subsequently, the HYSPLIT model is employed to precisely locate the sources and track the migration routes of specific representative sand and dust weather occurrences. Additionally, the study investigates the interplay between meteorological factors and dust events to elucidate the triggering mechanisms of these phenomena. Building on these findings, used to forecast PM10 concentrations for North China through random forest model. The findings indicate In March 19 to 23, 2023, North China witnessed dust events, with the episode from being the most intense and widespread in recent years. An analysis of the paths and sources of this sand and dust event revealed that the severe sandstorm in North China was the result of a synergistic effect of dust sources from Mongolia and Northwest China. The study identified a combination of meteorological factors—maximum wind speed > 6.1 m/s, relative humidity < 56%, and solar radiation > 128 w/m2—as having the most significant impact on sandstorm in North China. Leveraging these research outcomes, the study established an hourly PM10 prediction model for North China using random forest approach, with the highest accuracy for 1–3 hour forecasts. This study has advanced our understanding of dust and sand weather events to a certain extent,, furnishing a theoretical and scientific basis for the effective management of sand and dust in ecologically vulnerable regions.

Abstract

Aim
The study aimed to offer better genetic evaluation and consultation for DiGeorge syndrome (DGS) patients by combining screening of 22q11.2 and immunologic studies. A basic immune profile including the basic CD panel and immunoglobulins estimation was performed. TRECS and KRECS expression were studied in addition to measuring serum IL33, Obestatin, HLA-G, and Procalcitonin serum levels.
Methods
All investigations were performed for DGS patients (n = 33) and the matched control group (n = 45). Polymorphic 22q11.2 markers mapping was performed by PCR-STR technique. Lymphocyte subsets immunophenotyping was done using flow cytometry, while measurement of serum immunoglobulins was estimated using nephelometry. Real-time PCR was the method used for TRECs and KRECs measurement. Serum IL33, Obestatin, HLA-G, and Procalcitonin levels were determined using an Enzyme-linked immunosorbent assay (ELISA). Data was coded, tabulated, and statistically analyzed using SPSS version 19.0 software.
Results
In our case–control study, KREC expression was significantly elevated in DGS compared to healthy controls (P = 0.0008). There was also a significant increase in immunoglobulin levels in DGS. CD8% as well as CD8 absolute count in the patients with DGS were significantly lower than in the healthy control (P = 0.01273 and 0.05358 respectively). There were no significant differences in IL33, Obestatin, HLA-G, and Procalcitonin levels between DGS patients compared to the control group. Our results concerning the distinct segment of 22q11.2 as a DGS susceptibility region revealed an informative novel atypical interstitial homozygous deletion. This deletion included D22S944 and COMT absence, and D22S941 and D22S264 presence. Out of 33 DGS patients, three patients showed deletion in the D22S944 marker only in the presence of D22S941, and D22S264 markers. Therefore, we could assume that D22S944 is a common deleted marker in non-isolated DGS patients.
Conclusion
Combining 22q11.2 region screening, immune profile studies, and TRECS and KRECS expression offers a new comprehensive approach for DGS patients. This approach provides a better strategy for genetic consultation for DGS patients. Moreover, this study may be the first to show a small interstitial 22q11.2 deletion stereotype in a DGS patient and also showed that the smallest deletion at the 22q11.2 region is enough to confer the DGS phenotype.

Abstract

Background: Venous leg ulcer (VLU) represents one of the most severe clinical manifestations in the progression of chronic venous diseases (CVD), imposes substantial burdens on both patients and society. The etiology of VLU is associated with the impairment of vascular endothelial cells.
Methods: In clinical, a total of 10 patients diagnosed with VLU were enrolled in this study, and 4 types of skin tissue samples were collected from each patient, including normal, hyperpigmentation, lipodermatosclerosis, and VLU areas. Subsequently, the iron content and GPX activity were quantified. In vitro, iron overload models of HUVECs were established by exogenous 100μM FAC or 100μM Hemin to simulate simple iron overload and hemoglobin exudation, respectively. And ferroptosis medel was induced by 10μM Erastin. Meanwhile, Huoxue Shengji Decoction (HXSJ Decoction) as an external Chinese herbal decoction used in VLU treatment, has been incorporated into our in vitro study. Followed by the lipid peroxidation damage was evaluated by the content of malondialdehyde, protein carbonylation, ferrous ion, DCFH-DA and BODIPY™ 581/591 C11 staining; mitochondrial function was determined through ATP content and mitochondrial membrane potential (MMP) of JC-1 staining; the activation of Nrf2/system Xc-/GPX4 axis was assessed through GPX activity, GSH content, qPCR and western blot.
Results: The clinical results showed that, before progressing to VLU, iron deposition in the affected tissues of CVD gradually intensifies (P<0.05), and suddenly decreases in VLU stage (P<0.01). Meanwhile, in hyperpigmentation stage, the GPX activity increased significantly (P<0.05), with further deterioration of CVD, GPX activity was gradually suppressed (P<0.05). The in vitro results indicate that irrespective of iron overload or ferroptosis models, HXSJ Decoction effectively upregulated the expression of Nrf2, xCT, and GPX4 (P<0.05); inhibited the generation of malondialdehyde (P<0.01) and protein carbonylation (P<0.01), alleviated the accumulation of ferrous ions (P<0.05); restored MMP, promoted ATP production (P<0.05).
Conclusions: Overall, this study suggested that iron accumulation-mediated inactivation of GPX4 is a significant contributing factor in VLU development through ferroptosis induction. Additionally, it revealed that the therapeutic mechanism of HXSJ Decoction potentially involves mitigating ferroptosis by activating the Nrf2/system Xc-/GPX4 pathway and alleviating the accumulation of ferrous ions.
Physical Activity Lower Blood Pressure and Mortality in Hypertensive Patients with Diabetes: Data from National Health and Nutrition Examination Survey (NHANES) 1999-2018
Authors: Tang Lijiang , Zhong Xin , Liu Xiaowei , Zhang Zhi 
Published: April 2024

Abstract

Background: Previous studies on physical activity were generally focused on one or two types of activity, with few studies looking at mortality, and even fewer studies looking at patients with hypertension and diabetes. Therefore, the objective of this study was to investigate the relationship between physical activity and blood pressure and mortality in hypertensive patients with diabetes.
Methods: Hypertensive patients combined with diabetes were collected from the National Health and Nutrition Examination Survey from 1999 to 2018. These patients were categorized into the physical-active group, and the physical-inactive group. Multivariate Cox regression analysis was performed using T-test, Chi-square test, hazard ratio, and corresponding 95% confidence interval to investigate the effect of physical activity on mortality of hypertensive patients with diabetes.
Results: Physical activity had a significant negative correlation with systolic blood pressure(p=0.01) and among those taking antihypertensive drugs (p=0.0035). After adjusted for age, gender and race, there was still a significant negative association between physical activity and systolic blood pressure (p=0.03). In contrast, physical activity showed a positive correlation with diastolic blood pressure (p=0.002) and among taking antihypertensive drugs participants (p=0.02). In the unadjusted model, the physical-inactive group displayed notably higher risks of all-cause mortality and hypertensive mortality (p＜0.0001). Even after adjusted for age, gender, and race, the physical-inactive group demonstrate a significant increase in the risk of all-cause mortality and hypertensive mortality (p < 0.0001).
Conclusions: Physical activity can lower systolic blood pressure and reduce the mortality in hypertensive patients with diabetes.
The relation of school absenteeism with adolescent profiles of health behavioural-, psychosocial- and socio-economic characteristics: a cross-sectional study
Authors: Korpelshoek Lindi , Lans Rikkert Martijn , Crone Mathilde Rosalie 
Published: April 2024

Abstract

BACKGROUND: Several wide-range risk factors are associated with school absenteeism. Complexities arise from the multitude and clustering of these risk factors, challenging recognisability of adolescents at risk. This study aimed to identify usable adolescent profiles based on health behavioural-, psychosocial- and socio-demographic characteristics. School absenteeism outcomes of these profiles were compared.
METHODS: A total of 5,889 Dutch secondary school students completed a self-report questionnaire on (1) physical- and mental health, (2) health-related behaviours, and (3) school-, social- and family environments. Profiles of adolescents with similar characteristics were identified using a latent profile analysis. School absenteeism rates and reasons for absenteeism were compared among the identified profiles.
RESULTS: Four profiles were identified: profile A (10.1%), profile B (17.3%), profile C (60.7%) and profile D (11.9%). Two profiles (A, D) showed increased absenteeism risks, each displaying a combination of somatic, mental, social, and family-related problems. Profile A was characterized by psychosocial problems, while profile D was characterized by risk-taking behaviors. Both profile A and D were present across all educational levels.
CONCLUSIONS: The clustering of health behavioural, psychosocial, family and socioeconomic problems implies that school absenteeism requires a comprehensive approach, focusing not only on individual risk factors but also on the interaction of risk factors in an adolescent’s life. Knowledge about our identified profiles can be used to better recognize adolescents at risk and to tailor current interventions in practice, in order to decrease the burden caused by school absenteeism.
Exploring the Sugar Sweetened Drinks Tax (Sugar Tax) Pass Through Rate in the Irish Hospitality Sector

Published: April 2024

Abstract

Background
The WHO supports the use of Sugar-Sweetened Drinks Taxes (SSDTs) as a fiscal lever to help reduce sugar consumption and tackle obesity. Obesity is associated with a range of adverse health outcomes. In response to increasing levels of obesity in Ireland a SSDT was introduced in 2018. Previous research in Ireland has noted that the pass-through rate of the SSDT in retail (off-site consumption) settings was poor. However, to date no research has examined the SSDT pass-through rate in hospitality (on-site consumption) venues in Ireland.
Methods
This research examines the SSDT pass through rate on full-sugar versus diet versions of Coca-Cola in a convenience sample of 100 hospitality venues in two provincial Irish cities.
Results
In 88% of cases the same price was charged for both full-sugar and sugar free drinks.
Conclusion
It is generally assumed that the SSDT would result in persistent price differences between soft drink prices based on sugar content. However, this is barely evident in the hospitality sector in Ireland. A number of recommendations are suggested, including both increasing the SSDT, and increasing it annually in line with inflation.
