Published: January 2024

Postcovid syndrome includes many conditions and symptoms, both those that arose directly during the acute period of infection and the appearance of new ones. The purpose of the systematic review is to determine the criteria for the severity of postcovid syndrome. Materials and methods. The following keywords were used to search for literary sources: “postcovid syndrome”, “severity of postcovid syndrome”, “severity of postcovid syndrome” and “symptoms of postcovid syndrome” in Russian and English. We used the search engines “eLibrary.RU — Scientific Electronic Library” and PubMed.gov. Articles were included that presented a study of patients with laboratory-confirmed coronavirus infection at least a month after recovery from COVID-19 with residual clinical signs and/or biochemical changes. The analysis included only publications from the last 3 years (2020– 2023). Results. A total of 2,913 publications were found by two search engines. After removing duplicates, literature reviews, clinical studies of medicines, studies conducted on animals, studies unsatisfactory for time after acute COVID-19, and studies performed on persons under the age of 18, 69 articles were selected for analysis that meet the criteria for inclusion in the analysis. Conclusion. An analysis of the literature of the last 3 years has allowed us to determine that the presence and severity of postcovid syndrome can probably be determined by the presence in a patient of at least one of the signs presented in the review that developed during or after a laboratory-verified COVID-19 infection and persisted for more than 4 weeks from the onset of the disease and that cannot be explained by other reasons.

Many studies have shown that COVID-19 can progress with coagulopathy and multisystem thrombotic pathologies. This article presents the case of a patient who, 9 days after laboratory-confirmed coronavirus pneumonia against the background of anticoagulant therapy, was diagnosed with splenic infarction in combination with acute myocardial infarction during subsequent hospitalization. Prevention of thrombosis with prophylactic doses of low molecular weight heparin in hospitalized patients with COVID-19 may not be sufficient to prevent the development of coagulopathy. Abdominal visceral thromboembolism should be suspected in a COVID-19 positive patient with abdominal pain despite anticoagulant therapy and normal D-dimer levels.
Idiopathic Pulmonary Hypertension and in Situ Thromboembolism: A Difficult Case in Clinical Practice
Authors: Us M. A. , Karpenko Ju. Ju.
Published: January 2024

Pulmonary hypertension is a complex syndrome for differential diagnosis, which is the outcome of various pathological conditions. With the exclusion of the two most common causes of pulmonary hypertension, such as pathology of the left heart chambers and pulmonary embolism, further search for etiology often becomes problematic. Despite the emergence of a number of international and domestic recommendations, as well as certain successes in drug therapy, the long-term prognosis in patients with pulmonary arterial hypertension remains unfavorable. In the description of this clinical case in a 39-year-old woman suffering from idiopathic pulmonary arterial hypertension, the main complaint of the patient was very non-specific. The woman could not bear the child, all her attempts, lasting more than 19 years, remained unsuccessful. Even in absolutely healthy women, pregnancy is associated with the highest risks and is a powerful “test” of the body, not to mention patients suffering from rare diseases. The patient has a “subacute” course and a fairly rapid progression of the disease with a significant deterioration in the quality of life, which led to the impossibility of carrying a pregnancy. There were also signs that aggravated the prognosis, such as increased dyspnea, loss of consciousness, a significant decrease in working capacity and a high degree of pulmonary hypertension (according to echocardiography, systolic pressure in the pulmonary artery > 128 mm Hg). Due to the ineffectiveness of standard therapy with a selective inhibitor of cycloguanosine monophosphate — specific phosphodiesterase type 5 — sildenafil; the option of specific therapy for pulmonary hypertension was considered, which made it possible to change the situation and bring the patient into a stable state and draw conclusions about the pregnancy.

Authors: Oktaviani Nadhifa Dwi , Sadiq Nizamuddin
Published: January 2024

Numerous scholarly inquiries have been dedicated to exploring the advantageous consequences of implementing computer-mediated communication (CMC) for the purpose of orchestrating online group discussions. However, there is a paucity of empirical evidence elucidating how educators adapt to the use of CMC in the context of online group deliberations. The present research delves into the experiences of an English teacher in an Indonesian secondary school who employed CMC as a pedagogical tool. Grounded within the qualitative research paradigm, this study conducted unstructured in-depth interviews and subsequently subjected the interview transcripts to thematic analysis. The resultant findings shed light on several pivotal aspects of the teacher's role in CMC-enhanced online group discussions, which encompass the activation of students' creative faculties, the fostering of students' self-regulation of learning, the cultivation of a conducive learning environment, the advocacy for technological integration, and the effective management of assessment procedures in the online group discussion setting. Conclusively, this research posits that the incorporation of computer-mediated communication in online group discussions bears substantial educational advantages, as it affords students with alternative avenues to harness their skills and technology, thereby facilitating interpersonal exchanges among students and between students and educators.
Kewenangan Kurator atas Implementasi Business Going Concern Principle dalam Pengurusan Boedel Pailit
Authors: Sultan Almas
Published: January 2024

Law Number 37 of 2004 on Bankruptcy and Suspension of Debt Payment Obligations was formed to distribute the debtor's bankruptcy debt to creditors proportionally and fairly. A company that has been declared bankrupt but does not yet have insolvent status is not considered to have ended so bankruptcy will not stop business operations or can be called a business going concern. According to this law, companies can continue their operations even though they are deemed unable to pay their debts. This is different from what is explained in the Limited Liability Company Law which requires the dissolution of the company after it reaches a level of inability to pay debts. This raises questions that are formulated in the problem formulation, namely first, how to implement the principle of business continuity (Business Going Concern) in bankruptcy cases, second, what is the responsibility of the Curator due to the implementation of a going concern which fails in its implementation due to the company's stock valuation decreasing. This research uses a normative legal method supported by a statutory approach. The results of this research conclude that, firstly, if the curator assesses that there is potential to increase the valuation value of the bankrupt debtor, then going concerned is the right way as proven by analysis from the auditor to fulfill the debtor's achievements. Second, if after carrying out a business going concern the company's value continues to decline, then the curator should stop business activities and immediately settle the bankruptcy assets.

This study aims to determine the legal impact of the National Capital Plan's Land Freezing Policy on land owners who will make the transition. The problem is what is the legal impact of the National Capital Plan land freezing policy on land owners who will make the transition? This research includes normative legal research. Data in this research was collected using document/library studies and interviews which were processed in a descriptive-qualitative manner using a statutory approach. The results of this research show that the reservation policy in the National Capital Region of East Kalimantan has a regulatory impact, both positive and negative, on landowners who wish to transfer their rights. In essence, people cannot transfer their land even though they already have strong rights and reasons to sell their land, and these reasons are not what the government is worried about. So several things then give rise to legal uncertainty and several values related to land acquisition that conflict between one regulation and another. The government needs to be more specific and mature in formulating policies so that they do not appear authoritarian and reactionary, while at the same time organizing the process of transferring land in the Capital Planning Area to a task force, one of which is conducting investigations.
Akibat Hukum Pembiayaan dengan Akad Musyarakah Mutanaqishah yang dilaksanakan Secara di Bawah Tangan
Authors: Nur Vikron P Ahmad
Published: January 2024

Financing can be done using various types of contracts, one of which is: the musyarakah mutanaqishah contract. The agreement that arises from the contract is stated in the deed. Deeds consist of 2 (two) forms, namely authentic deeds and private deeds. An authentic deed provides perfect evidentiary power, while a private deed does not have perfect evidentiary power. Ideally, financing is carried out with an authentic deed. However, in practice, financing still occurs with a musyarakah mutanaqishah contract which is carried out privately, and then legalized before a notary. Based on this, it is necessary to conduct research regarding the legal consequences of financing with musyarakah mutanaqishah contracts carried out privately. The researcher formulated a problem formulation regarding what are the legal consequences of a financing deed with a musyarakah mutanaqishah agreement that is executed privately? The research method used is normative with literature study. The results of the research conclude that the contract executed remains valid and binding as law for the parties as long as the terms and conditions of the contract are fulfilled. A private deed that is legalized before a notary is stronger than a private deed that is not legalized. However, the strength of the evidence is not perfect and still requires the judge's consideration regarding the strength of the evidence-based on Article 1881 paragraph (2) of the Civil Code.
The Geometrization of Maxwell’s Equations and the Emergence of Gravity and Antimatter
Authors: Beach Raymond
Published: January 2024

Coupling the Maxwell tensor to the Riemann-Christoffel curvature tensor is shown to lead to a geometricized theory of electrodynamics. While this geometricized theory leads directly to the classical Maxwell equations, it also extends their physical interpretation by giving charge density, mass density and the four-velocity that describes their motions geometric definitions. Assuming the existence of a conserved energy-momentum tensor, all solutions to the geometricized theory of electrodynamics developed here are shown to be consistent with the emergence of gravity obeying the General Relativity field equation augmented by a term that mimics the properties of dark matter and/or dark energy. Finally, due to the symmetries of the theory, the properties and phenomenology of antimatter emerge in solutions.

Published: January 2024

The quality of veterinary medicinal products (VMP) is essential for efficient disease management. Therefore, VMPs that do not meet the required standards of quality can lead to increased sickness, death, and the development of antimicrobial resistance, posing a danger to both animals and humans. This study aimed to identify substandard and falsified VMPs on the Rwandan market using the Global Pharma Health Fund (GPHF)-Minilab™. VMP samples were purchased and collected in a cross-sectional study from veterinary retail pharmacies from five districts in four provinces of Rwanda, during May and June 2023. These samples were transported to the Veterinary Laboratory of the School of Animal Sciences and Veterinary Medicine, Nyagatare campus, University of Rwanda, and stored until analysis. The samples were subjected to physical and chemical analysis following the GPHF-Minilab™’s guidelines. A total of 130 samples from two categories of VMP were purchased from 10 veterinary retail pharmacies in urban and rural areas. The results of this study revealed that none of the assessed VMP samples failed physical tests (visual inspection, weight verification, and disintegration test). 10 samples (Sulfamethoxazole/Trimethoprim) out of 130 (7.7%) passed the visual inspections but later failed to comply with Thin-Layer Chromatography result specifications. This is an indication of the presence of substandard and falsified VMP circulating in Rwanda that warrants regular inspection and chemical quality control of VMPs along the supply chain.
A Systematic Approach to Designing Power Sharing Control of Converter-Based Generators
Authors: Hossain Mohammad Alomgir , Hossain Md Alamgir , Pota Hemanshu Roy , Hattori Haroldo T.
Published: January 2024

This paper introduces a structured design for an effective power-sharing technique among converter-interfaced distributed generation (DG) units within a microgrid that operates without a synchronous generator. The proposed power-sharing technique leverages the battery energy storage system (BESS) to promptly respond to network changes. The real power output of each commercial distributed energy resources (CDER) unit is governed by a frequency-droop characteristic and a complementary frequency restoration strategy. Deloading techniques are employed by solar and wind power generators to enhance response during power supply or demand disturbances. To ensure microgrid stability, small-signal analysis is conducted for controller design, including the determination of stability margins. Initial tuning of the power-sharing technique parameters is achieved using the Ziegler-Nichols Method, followed by further optimization through a meta-heuristical algorithm to enhance the response time of energy sources. The proposed power-sharing technique's performance is evaluated on a benchmark medium voltage network using industry-standard commercial software. The test results demonstrate the precise and rapid power-sharing capabilities among DGs facilitated by the proposed technique, highlighting its effectiveness in dynamic microgrid environments.

Published: January 2024

Contamination of the environment with nano- and microplastic particles exerts a threatened impact on the aquatic ecosystems and sustainable catfish aquaculture. The presence of nanoplastics has been found to have a detrimental impact on both aquatic and terrestrial ecosystems. The present study examines the effect of polystyrene nanoplastics on DNA, erythrocytes, oxidative status and renal of catfish in addition to the potential protective effects of Chlorella vulgaris bioremeditation and selenium to hinder this effect. Six equal groups of fish were used as follows: Group 1: served as a control group and received water free from PS NPs; Group 2: was exposed to PS NPs at a concentration of 5mg/L; Group 3: was exposed to PS NPs (5mg/L) + selenium (1mg/kg diet); Group 4: was exposed to PS NPs (5mg/L) + C. vulgaris (25g/kg diet); Group 5: was supplemented with C. vulgaris (25g/kg diet); and Group 6: was supplemented with selenium (1mg/kg diet). The results indicated that PS NPs induced oxidative stress by significantly elevating MDA activities and slightly reducing antioxidant biomarkers, resulting in DNA damage, increased frequency of micronuclei, erythrocyte alterations, and numerous histopathological alterations in kidney tissue. Selenium and C. vulgaris significantly ameliorated the oxidative/antioxidant status, reduced DNA damage, micronucleus frequency, erythrocyte alterations, and morphology of kidney tissue. Nevertheless, further research is needed to evaluate in detail the mechanism behind the toxicity with nano-microplatics in aquatic system.

Published: January 2024

In recent years, the advances in sperm morphology and genetic analyses in Perumytilus purpuratus allowed to suggest two evolutionary scenarios for this mussel: 1) the scenario of cryptic species and 2) the scenario of incipient or in progress speciation. To a better understanding of the evolutionary history of P. purpuratus, we performed an extensive sampling effort along a latitudinal gradient of ca. 7,180 km of coastline, from Southern Pacific to Atlantic Oceans and, we have also gone deeper in sperm morphology in P. purpuratus, exploring its association with phylogeny and population genetics to contrast if variability in sperm traits between northern and southern regions are signals of cryptic or incipient species. Overall, our results showed three sperm morphotypes and genetic structure in males of P. purpuratus strongly correlated. Additionally, we found evidence of a genetic admixture between lineages suggesting an introgressive hybridization zone at 38°S. These findings suggest the hypothesis that P. purpuratus is under incomplete reproductive isolation, with the presence of mechanisms of postzygotic isolation between lineages and, therefore, under an incipient or in fraganti speciation process. Finally, we discovered a new long morphotype for this species restricted to southern localities. Overall, our results support the hypothesis of historical events and postglacial recolonization as causal phenomena for the observed divergences.
Precision Farming: A New Era of Antibiotic-Free Agriculture
Authors: Bothe Hemant , Kamble Laxmikant , Bothe Santosh
Published: January 2024

Precision farming is transforming how antibiotics get used on farms. It fights the overuse that creates superbugs and harms nature. Farmers now have high-tech tools to use antibiotics ultra-precisely. Drones, AI, and advanced watering equipment help them pinpoint only sick plants and animals needing treatment. This shields crops while avoiding environmental damage. More careful antibiotic use makes livestock healthier and boosts harvests too. And it prevents resistant germs, where antibiotics stop working altogether. The approach helps farms in multiple ways, using fewer resources for even better results. There are some growing pains, like high costs for small farms. And questions around data privacy also cause concern. But overcoming these hurdles could help precision farming spread far and wide. This technology promises safer, greener, and more productive agriculture. Targeted use of antibiotics protects both crops and people from drug-proof germs. And nature benefits when less medicine spreads into soil and water. The future looks bright for farming with precision.
Modified Bertaut Method to Determine Cation Distribution and Valence State in Powders of Spinels Through X-ray Diffraction
Authors: Hernandez de la Cruz Jose Alonso , Mani Gonzalez Pierre Giovanni
Published: January 2024

In this work a new method is proposed to tackle down the multiple objective optimization problem of the calculation of cation distribution in spinels structure, through the difference of intensity ratios between experimental and calculated intensities of cation sensitive Bragg planes, by introducing a new factor, Rabs, in Bertaut method. This factor is introduced as the sum of absolute R factors, and it is minimized by varying cation distribution. To test this method aluminate manganese spinel where synthesized though modified Pechini method and characterized though XRD. The results show to be in agreement with literature for the aluminum inversion in tetrahedral sites, which is near to the reported value of 10%. Also, it was noticed that the manganese atoms are present in octahedral sites with a mixed valence state of +2 and +3. Which might be an indicator that oxygen vacancies are present in the structure, so the vacancies value of oxygen is proposed considering the total charge of cations and thus proposing the value of 3.678 mol per formula unit of the spinel, thus having the next stoichiometry considering normalized Al and Mn, MnAl2O3.678. Finally, the last cation distribution proposed was [Mn0.867^(+2) Al0.129^(+3) ][Mn0.034^(+2) Mn0.098^(+3) Al1.871^(+3) ] O3.678 with a Rabs factor value of 0.6466, which considers the cation distribution and oxygen vacancies.

Published: January 2024

Novel Ca3(BTC)2 metal-organic frameworks with different sizes and shapes constructed by Ca2+ and trimesic acid as metal center and ligands respectively were synthesized by a surfactant-assisted method. The relationship between the quantity of surfactant and the particle morphology of the product have been further studied. The samples were characterized by scanning electron microscope, powder X-ray diffraction and Inductively coupled plasma mass spectrometry. The results indicated that the size and shape of Ca3(BTC)2 could be regulated by changing the quantity of surfactant. Rod- and sheet-like Ca3(BTC)2 MOFs have been readily availabled. The removal kinetics of heavy metals of Pb(II) were also studied by rod-like Ca3(BTC)2. The results showed that as-synthesized Ca3(BTC)2 could effectively remove heavy metals of Pb(II) from the sewage.

We investigated if the abnormal sleep-wake rhythms in infants are related to the future development of autism spectrum disorder (ASD), using questionnaire from September to October 2016. The parents of a total 160 children with ASD (male, n=123; female, n=37) recruited from the two hospitals in K and H cities and as a control group, 145 children (male, n=75; female, n=70) recruited from four nursery schools in T city. Fisher’s exact test was used for the comparison of categorical variables. The associations of bedtime and waking time on weekdays and holidays in infancy, at 1-3≦ (1-3) years of age and at 3-5 ≦ (3-5)years of age with the prevalence of ASD were analyzed using a multivariable logistic regression analysis. Especially by 3 years of age, the following factors were associated with an increased risk of developing ASD in the future: 1) short sleep (<8h), 2) long time to fall asleep (>60min), 3) sleep onset time after 22:00h, 4) wake-up time after 07:00h and/or 08:00h on weekdays and holidays, respectively, 5) frequent (>3 times) and long-term awakening (>60min).
Misalignment and/or shift of the sleep-wake circadian rhythm in infant may be one of the precursors and/or risk factor to the future development of ASD.

Published: January 2024

Artificial Intelligence (AI) made its first appearance in 1956, and since then it has progressively introduced itself in healthcare system and patients’ information and care. AI functions can be grouped under the following headings: Machine Learning (ML), Deep Learning (DL), Artificial Neural Network (ANN), Convolutional Neural Network (CNN), Computer Vision (CV). Chronic limb-threatening ischemia (CLTI) represents the last stage of peripheral artery disease (PAD), and has increased over recent years, together with the rise in prevalence of diabetes and population ageing. Nowadays AI grants the possibility of developing new diagnostic and treatment solutions in the vascular field, given the possibility of accessing clinical, biological, and imaging data. By assessing the vascular anatomy in every patient, as well as the burden of atherosclerosis, and classifying the level and degree of disease, sizing and planning the best endovascular treatment, defining the perioperative complications risk, integrating experiences and resources between different specialties, identifying latent PAD, thus offering evidence-based solutions and guiding surgeons in the choice of the best surgical technique, AI challenges the role of the physician’s experience in PAD treatment.

Catheter-associated bloodstream infection (CVC-BSI) is a significant cause of morbidity and mortality among hemodialysis patients. In our center was a notable increase in CVC associated with patient age and morbidity. This 10-year retrospective study investigated catheter-associated bloodstream infections (CVC-BSI) in hemodialysis patients. We recorded a total of 67 bacteremia episodes in 52 patients, predominantly linked to Gram-positive microorganisms, particularly Staphylococcus aureus, the study found a mean age of 68 years, 74.6% males, and 88% with tun-neled jugular catheters. Notably, catheter removal occurred in 65.7% of cases, more frequently in Gram-positive instances. Two episodes of endocarditis and five ICU admissions were reported. The study identified a higher incidence in the summer and a significant decrease in bacteremia from 2017, coinciding with the introduction of Tauro-LockTM. Despite enhanced preventive measures during the COVID-19 pandemic, there was no significant impact on catheter infection rates. This research emphasizes the importance of early catheter removal, highlights seasonal variations in incidence, and suggests a potential positive influence of Tauro-LockTM on de-creasing CVC-BSI rates in hemodialysis units.

Machine learning (ML) based on neural network (NN) facilitates data-driven techniques for handling large amounts of data, either obtained through experiments or simulations at multiple spatio-temporal scales, thereby finding the hidden patterns underlying these data and promoting efficient research methods. The main purpose of this paper is to extend the capabilities of a new solver, called realFluidReactingNNFoam, under development at University of Perugia in OpenFOAM with NN algorithm for replacing complex real-fluid thermophysical property evaluations, using the approach of coupling OpenFOAM and Python-trained NN models. Currently, NN models are trained against data generated using the Peng-Robinson equation of state (PR-EoS) assuming mixture frozen temperature. The OpenFOAM solver, where needed, calls the NN models in each grid-cell with appropriate inputs, and the returned results are used and stored in suitable OpenFOAM data structures. Such inference for the thermophysical properties is achieved via the “Neural Network Inference in C made Easy” (NNICE) library, which proved to be very efficient and robust. The overall model is validated considering a liquid-rocket benchmark comprised of liquid-oxygen (LOX) and gaseous-hydrogen (GH2) streams. The model accounts for real-fluid thermodynamics and transport properties, making use of the PR-EoS and the Chung transport models. First, the development of a real-fluid model (RFM) with artificial neural network is described in detail. Then, the numerical results of the transcritical mixing layer (LOX/GH2) benchmark are presented and analyzed in terms of accuracy and computational ef-ficiency. Results of the overall implementation indicate that the combined OpenFOAM and ML approach provides a speed-up factor higher than seven, while preserving the original solver accuracy.

Contactless charging is evolving fast in many domains and applications such as the electrical vehicles (EV). The principle consists of transferring energy between two systems without having any electrical connection between them. This power transfer can be realized by emitting a magnetic field for Inductive Power Transfer (IPT). In the automotive domain, the application of contactless charging to supply power to the vehicle while driving is one of the solutions envisaged to solve the limited autonomy range of EV and reduced its cost but the system must comply with existing standards (e.g., allocated frequency range and radiated electromagnetic emissions), as summarized in this paper.

Provenance trials provide a valuable opportunity to evaluate the impact of extreme events on growth and wood properties. In this study, we have evaluated 81 Norway spruce provenances, tested in three provenance trials established in the Romanian Carpathians in 1972. The response to drought of the Norway spruce provenances – resistance, recovery, resilience, and relative resilience, has been examined, as well as the relationship between climate and growth, and the correlations between wood traits, the coordinates of origin and drought resilience indices. In each provenance trial, there were significant differences between provenances and years regarding wood widths and latewood percentage (LWP). Regarding the drought extreme events, the years when it occurred in all three provenance trials were 2000 and 2003. Significant differences between provenances for at least one drought resilience index have been found in all provenance trials, for the year 2000. By using subperiods of 25 years, changes in the relationship between climate and growth have been observed. Several provenances with high radial growth and good resistance and/or recovery have been identified. Provenances that performed better in common garden experiments could be used in assisted migration even beyond the current natural range.

Lentil (Lens culinaris Medik) is an annual herb that belongs to family Fabaceae, it is one of the most ancient food crops that has been grown in the world, and originated from southwestern Asia as early as 7000 BC. In Spain lentil acreage raised 42,200 ha in 2022, two authonomous regions Castilla-León and Castilla-La Mancha are traditionally the large producers. Lentils have the capacity to fix atmospheric N2 in symbiosis with rhizobia and, additionally it is considered moderately tolerant to drought which in turn makes this pulse a low water and carbon fingerprint crop. The aim of this study was to assess the symbiotic responsiveness to rhizobia strains of several lentil accessions from the Spanish germplasm bank, to determine the nutritional value and mineral seed composition and, to evaluate the agronomic performance of six selected accessions in two regions under rainfed conditions and different management systems. The protein content of all genotypes was higher than 25%, with two outstanding seeds from accessions: BGE025596 and BGE026702 which account for >30% of protein and <2% of fat. Accessions BGE016362 and, BGE026702 had an exceptional Fe content, > 1 g/100 g of seed flour. The agronomic performance varied depending upon the cropping región.
