Published: April 2024

The paper deals with the problems of maintaining Ukraine’s grid reliability under high renewable electricity penetration and improving state policy measures to accelerate sustainable energy transition in the post-war period. Promoting renewable energy in Ukraine increased renewable electricity share in the country’s electricity mix to 13.8% in 2021. However, such growth became critical for Ukraine’s electric power system. Due to its inflexibility, the lack of balancing and energy storage capacities, adding significant amounts of renewable electricity to the grid created severe problems. Further renewable energy development required serious reforming policy measures, but the Russian invasion prevented introducing relevant legislative changes. At the same time, the war had an unprecedented impact on the Ukrainian energy sector, resulting in the damage of more than 50% of the energy infrastructure. Considering global trends towards decarbonisation and achieving climate neutrality, reconstructing Ukraine’s electric power sector will be based on the large-scale involvement of renewable energy technologies. Given this, based on the study of the trends in renewable energy development in the pre-war and war-time periods and the analysis of the shortcomings of the state energy policy, the paper examines the required measures for fostering resilient reconstruction of Ukraine's electric power sector.

Authors: Ilahi Mounira , Cheniti Belcadhi Lilia , Ayad Omar
Published: April 2024

Technology Enhanced Learning Environments (TELE) have attracted many learners to acquire knowledge and skills at their own pace. But the majority of these environments are not accessible for all categories of learners including learners with disabilities. In fact, some environments may provide content during the learning process that does not meet the profiles of every type of disability. Much research has been developed in the area of personalizing e-learning for people with disabilities. The use of assessment analytics, on the other hand, remains largely unexploited despite its great informative potential, which is elated to assessment data generated by online learning environment. Our proposal focuses on the design of a scenario model for Assessment Analytics to develop a recommendation framework for learners with disabilities. This framework is conceived to retrieve and select relevant learning and assessment resources to learners with disabilities based on their preferences, accessibility needs, and assessment trace data in the context of online learning.

Review of Methods for Converting Biomass into Biofuels
Authors: Lesiak Paweł
Published: April 2024

Thermochemical processes are among the most effective methods of obtaining hydrogen-rich gases from biomass. These technologies mainly include pyrolysis, gasification and hydrothermal liquefaction. Thermochemical conversion of dry biomass is similar to the conversion of fossil fuels using gasification and pyrolysis methods. Products obtained through thermochemical processes (CO and CH4) can be processed into other biofuels, e.g. syngas, a raw material for producing synthetic hydrocarbons, methanol and alcohols. In recent years, advanced research has been carried out using biomass to produce liquid fuels. The biomass pyrolysis process in the presence of a catalyst is based on the rapid heating of the biomass to a temperature of approximately 500°C in the so-called inert atmosphere in which there are no reactive gases. This process produces a liquid product: pyrolysis oil, gas and charcoal. The bio-oil produced in this process constitutes 60-75% of the mass of the biofuel and is thermally unstable because it contains up to 300 different chemical compounds. However, the bio-oil obtained in this way is incompatible with conventional liquid transport fuels (gasoline, diesel) due to its high oxygen content. Pyrolysis in the presence of a zeolite catalyst is a process that allows for the effective conversion of biomass in economic and ecological terms. A zeolite catalyst makes it possible to remove oxidized compounds in situ and modify the properties of the biofuel to ensure its compatibility with conventional transport fuels. The catalyst plays a crucial role in this process because it removes oxygen from oxygenates and, consequently, creates stable reaction products that can then be treated to obtain renewable transport fuels or other useful chemicals. The article presents methods of biomass conversion via pyrolisis, microorganisms usage, zeolite-based catalysis, biocatalysis and photo-fermentation, which poses a big possibility of diversification of renewable energy sources.

Published: April 2024

Background and Objectives: The management of intra-abdominal collections in fistulising Crohn’s disease (CD) has traditionally involved surgery. However, conservative management is a potential alternative. In this study, we report our experience with multi-modal conservative management of intra-abdominal collections secondary to perforating CD. Methods: Medical records of CD patients with a history of intra-abdominal collections or fistulas over the past five years were reviewed retrospectively. Patients were included if they were initially managed conservatively using any combination of antibiotics, exclusive enteral nutrition (EEN), percutaneous drainage of collections, endoscopic dilatation of associated strictures and medical therapy for IBD with steroids, immunomodulators and/or biologics. Results: Eleven participants were included. All participants had penetrating CD affecting the terminal ileum. Nine participants had intra-abdominal collection on cross-sectional imaging whilst the remaining two participants had fistulising disease and sepsis without a discrete collection. Eight participants completed a 6–8 weeks course of EEN. All participants were treated with antibiotics and a thiopurine. Steroids were used in eight participants and biological agents in six. Six participants underwent endoscopic dilatation of small bowel strictures. After a median follow up of 20 months [range: 3–210] nine participants had evidence of adequate clinical, biochemical, radiological and endoscopic improvement. Complete resolution of abscess was seen in 4/7 participants and a significant reduction in abscess size was seen in 2/7. Two participants had complete endoscopic and histological remission and complete resolution of abscess. Both participants with fistulising disease (without a collection) had evidence of healed fistula tract on progress imaging and endoscopy. Two participants underwent surgery after failure of initial conservative management. Conclusion: Intra-abdominal collections in fistulising CD can be managed successfully in appropriately selected patients using a multi-modal approach incorporating antibiotics, EEN, endoscopic dilatations of culprit strictures and optimised medical management using steroids (for induction of remission), immunomodulators and biologics.

Published: April 2024

Objectives: The improvement of prediction for adverse pregnancy outcomes is quite essential to the women suffering from pre-eclampsia, while the collection of predictive indicators is the prerequisite. The traditional knowledge-based strategy for variable selection confronts challenge referring to dataset with high-dimensional or unfamiliar data. In this study, we employed five different automatic variable selection methods to screen out influential indicators, and evaluated the performance of constructed predictive models. Methods: Seven hundreds and thirty-three Han-Chinese women were enrolled and 56 clinical and laboratory variables were recorded. After grouping based on binary pregnancy outcomes, statistical description and analysis were performed. Then, utilizing forward stepwise logistic regression (FSLR) as the reference method, another four variable selection strategies were included for filtering contributing variables as the predictive subsets, respectively. Finally, the logistic regression prediction models were constructed by the five subsets and evaluated by the receiver operator characteristic curve. Results: The variables confirmed statistical significance between the adverse and satisfactory outcomes groups did not overlap with the variables selected by selection strategies. “Platelet” and “Creatinine clearance rate” were the most influential indicator to predict adverse maternal outcome, while “Birth weight of neonates” was the best indicator for predicting adverse neonatal outcome. In average, the predictive models for neonatal outcomes achieved better performance than models for maternal outcomes. “Mutual information” and “Recursive feature elimination” were the best strategy under current dataset and study design. Conclusions: Variable selection strategies may provide an alternative approach besides picking influential indicators by statistical significance. Future work will focus on applying different variable selection methods to the high-dimensional dataset, which includes novel or unfamiliar variables. This aims to identify the most appropriate collection of predictors that can enhance prediction ability and clinical decision-making.
Placental biomarkers of fetal-originated diseases

Published: April 2024

Fetal-originated diseases refer to birth defects of offspring and multiple chronic diseases in adulthood caused by abnormal embryonic development. However, due to the vulnerability of the fetus/ neonate and technical limitations, it is very difficult to carry out effective development assessment and early warning of long-term diseases in the early stages of life. It is known that the placenta is the unique link between the mother and the fetus, and its role in the occurrence and progression of fetal-originated diseases cannot be ignored. Studies have found that a variety of adverse environmental factors (such as nanoparticle exposure) cannot pass through the placental barrier, but can lead to fetal dysplasia and multi-organ development programming changes by affecting placental development, and ultimately mediate the occurrence of fetal-originated diseases. Meanwhile, some environmental factors that can pass through the placental barrier can cause placenta-fetal co-exposure, resulting in similar signaling pathways and epigenetic changes. The placenta originates from the fetus and the mother, and its development is accompanied by changes in indicators that can be objectively and quantitatively detected. These factors can be used as a biomarker to assess maternal exposure, and placental function, and to predict the developmental status and long-term disease susceptibility of offspring. To date, researchers have discovered a variety of potential placental biomarkers, and show promising application prospects. This paper reviews the recent research on placenta-related mechanisms leading to fetal-originated diseases and placental biomarkers, to provide the theoretical and experimental basis for early warning, prevention, and treatment of fetal-originated diseases.

Bài báo mô tả một phương pháp nâng cao chất lượng ảnh hồng ngoại bằng cách trộn ảnh từ hai nguồn ảnh camera thường và ảnh hồng ngoại cùng quan sát một cảnh. Hai ảnh từ hai camera khác nhau không có cấu trúc dữ liệu thống nhất: độ phân giải khác nhau, trường nhìn khác nhau (FOV) và điều chỉnh ống kính khác nhau. Để thực hiện việc nâng cao chất lượng một nguồn ảnh, trước tiên các hình ảnh phải được biến đổi về cùng điều kiện. Sau đó, hai ảnh được trộn với nhau để nâng cao chất lượng ảnh hồng ngoại. Kết quả thực nghiệm cho thấy tính hiệu quả của phương pháp khi chất lượng ảnh hồng ngoại được nâng cao.
