The relevance of research is determined by the need to assess the degree of transformation of quartz raw materials in its natural occurrence, as well as, changes in the properties of raw materials and products are exploited under various operating conditions. X-ray diffraction and Infrared spectroscopy was used to assess the degree of crystallinity of various crystalline quartz materials and products made of silicon dioxide, which showed satisfactory convergence of results and can be recommended for use in world practice. Objects: artificially grown quartz, including samples of synthetic quartz with an admixture of aluminum, zone-colored single crystal of quartz with an admixture of two and ferric iron; natural crystals of amethyst, smoky quartz, optical quartz; samples of fused quartz, products made of technical and optical quartz and silicate glass; as well as fine-grained samples of quartzites, including their micro- and nano-sized fractions. Methods: optical and electron scanning microscopy, X-ray spectral and analysis, infrared spectroscopy, X-ray diffraction. Results. The paper shows that the degree of crystallinity of quartz raw materials and products based on it is determined by the presence of a structural ordering in the near zone that characterizes the crystalline state corresponding to the a-quartz phase, which is confidently recorded by XRD and FTIR  methods. The local disorder of high-purity quartz or quartzites having various impurities or defects in their structure that arise under the influence of external influences  or exploitation causes deterioration of their properties and decrease in the degree of crystallinity.

The relevance. The use of Russia's hydroelectric potential for electricity generation is one of the cleanest and environmentally friendly methods as it does not result in the emission of harmful substances and carbon dioxide into the atmosphere. Moreover, it is a reliable and efficient source of energy as water is a constant source of energy. Hydro turbines are used to convert the energy of water flow into electrical energy, which effectively ensures more reliable and stable production capacity for hydroelectric installations. However, micro-hydroelectric power plants have some drawbacks related to difficulties in ensuring the high quality of produced electricity of autonomous power supply systems. This is due to the fact that the load on the autonomous power supply system can vary not only in magnitude but also in nature, which makes it difficult to maintain a stable level of electricity production. The main goal of the research is to determine the ranges of variation of the output electrical parameters of a non-regulated hydrogenerator operating as part of an inverter-based micro-hydroelectric power station for rural domestic consumers. Additionally, the task is to formulate requirements for the hydrogenerator and power conversion devices in static and dynamic operating modes of the autonomous power supply system. Object: inverter-based micro-hydroelectric power station. Methods: simulation modeling, and programming in Matlab Simulink. Results. A simulation model of an electric power supply system with an inverter microelectric power station was developed. The structure of microelectric power station is proposed, as well as the ranges of voltage changes of the microelectric power station generator are obtained.
LA GROTTESCA E IL RITRATTO. IMMAGINE E COSTRUZIONE DI SÉ NEI SAGGI DI MONTAIGNE
Authors: Ferraguto Federico
Published: August 2023

L’articolo analizza la funzione dell’immagine nei Saggi di Montaigne individuato da un duplice movimento, che è di presa di distanze dall’esistente e di ridefi nizione dell’esistente nei termini di nuove forme, criticamente consapevoli, di abitare il mondo. A tal fine, l´articolo prende in considerazione alcuni temi-chiave che possono essere riscontrati nei Saggi (l´autodescrizione, la critica al sapere sensibile, la deformità e la critica all´abitudine) con l´obiett ivo di riflett ere sul potenziale ontologico della immagine come Bildung e sul modo in cui tale potenziale si riverbera nella concezione montaigneana dell´arte di vivere e in particolare di come, non la teoria, ma la pratica dell’immagine apra lo spazio per una definizione creativa, ma non arbitraria, dell’esistente.

O CETICISMO QUANTO À RAZÃO EM HUET E HUME
Authors: De Holanda Pereira Campelo Wendel
Published: August 2023

A despeito de ser bem menos conhecido atualmente, o problema do ceticismo quanto à razão foi um assunto bastante relevante entre os autores dos séculos XVII e XVIII, da mesma maneira que o ceticismo quanto ao mundo exterior. Nesse sentido, busco apresentar os impactos de Huet sobre a posição de Hume no que concerne ao ceticismo quanto à razão do Tratado da Natureza Humana, particularmente a partir da versão pirrônica elaborada por Huet do argumento cartesiano do “Deus enganador”. Assim, como mostrarei neste trabalho, Hume está correto pelo menos ao associar o argumento cético quanto à razão ao ceticismo pirrônico.

A CONTROVÉRSIA DE AUXILIIS: EM TORNO À SEMÂNTICA DAS SENTENÇAS TEÓRICAS DO DISCURSO FILOSÓFICO E TEOLÓGICO E À NECESSIDADE DE UMA METAFÍSICA PRIMORDIAL
Authors: Sureki Luiz Carlos
Published: August 2023

De Auxiliis designa uma famosa controvérsia filosófico-teológica do final do século XVI e início do século XVII, que envolveu teólogos espanhóis dominicanos e jesuítas em torno do tema/problema do livre arbítrio humano sob a influxo da graça divina. Considerado filosoficamente, o problema central gira em torno à determinação semântica de enunciados condicionais contrafactuais, problema este já presente em todos os enunciados teóricos composicionais. A partir do contexto histórico e teológico da controvérsia, juntamente com o surgimento do Molinismo, apresentaremos, com alguns aportes da Filosofia Estrutural-Sistemática proposta por Lorenz Puntel, o problema filosófico da determinação semântica de sentenças teóricas em geral e a nova forma de determiná-las semanticamente. Isso possibilitará a elaboração filosófica de uma nova Teoria do Ser, na qual a grande questão de “Deus” e seus atributos encontrará seu mais adequado lugar teórico no discurso filosófico sistemático.

Published: August 2023

Various studies on the physical characteristics of the canopy gaps in tropical and subtropical regions but that in the mangrove swamp forest in Malaysia is little known. The objectives of this study are to assess the canopy gaps physical characteristics (size, form, direction), to assess the changes in soil physical characteristics and microenvionment in and around the canopy gaps. Five canopy gaps were selected formed by lightning strikes, gaps size and shapes were determined using the portable Global Positioning System and photographic images were analysed using ForestCrown. Result shows that canopy gap opening has increased the total light reaching the forest floor, changed the canopy gap microenvironment. Strong correlation between canopy opening percentage and temperature of gaps explains the changes of canopy gaps characteristics. These changes have contributed to new seedling germination, regeneration and maintaining the canopy gap dynamics.

Published: August 2023

Being a great source of protein, B-vitamins and minerals, meat and fish are staple foods in many cultures. However, cooking at high temperatures can produce chemicals associated with an increased risk of developing cancer. This review investigates the possible carcinogenic activity of chemicals formed during the cooking of meat and fish including heterocyclic amines (HCAs), polycyclic aromatic hydrocarbons (PAHs), and advanced glycation end products (AGEs). High-temperature cooking methods for meat, including grilling or frying, result in the formation of HCAs. Meat that has been smoked, grilled, or cooked over an open flame produces PAHs whereas, dry heat methods including roasting, grilling, and frying results in formation of AGEs. In vitro studies have shown that these compounds can damage DNA, cause mutations, and promote the growth of cancer cells. Research shows that thoroughly cooked meat increases the risk of cancer, particularly colorectal, pancreatic, and prostate cancer. Alternative cooking techniques, marinades, and incorporating fruits and vegetables can help to mitigate this risk. For determining the efficacy of these measures, additional studies are required. For the purpose of lowering the potential carcinogenic activity of chemicals formed during the cooking of meat and fish, mitigation techniques must be understood and put into practice. Cancer can be avoided by informing people about the dangers of eating meat and fish that have been cooked at high temperatures and by encouraging better diets and cooking styles. In order to lessen the possible health concerns related to the eating of meat and fish, further studies are required.

Published: August 2023

Land use and land cover (LULC) datasets for Jinan in 1992, 1998, 2002, 2006, 2011, 2017, and 2022 were developed from Landsat images using the Random Forest (RF) classification approach. The relationships between social-economic, political factors and time-series LULC data were exam-ined for the periods between 1992 and 2022. The results showed the effectiveness of using the RF classification method for LULC classification with time series of Landsat images. Combined with driving forces analysis, our research can effectively explain the detailed LULC change tra-jectories corresponding to different stages and give new insights into Jinan LULC change pat-terns. The results show a significant increase in impervious surface which opposite change to bare land which experienced a huge decline declined by 95%, due to urbanization and rapid in-crease of population. The driving forces behind these changes are related to population growth, economic development, and climate change. Moreover, the present research employed Principal Components Analysis (PCA) methodology in order to understand the relative significance of disparate driving factors. The analysis results prove that the economy (population, GDP) and climate change were the primary factors that have an obvious impact on land use/land cover changes and that the driving factors for impervious surface, bare land, woodland, farmland, and water were distinct. Government policies also have a substantial impact on LULC change as well, such as the Construction of Harmonious Jinan (COHJ). The results were helpful for better understanding the mechanisms of LULC change and can provide useful knowledge for effective land resource management and planning.

Published: August 2023

Existence of hybrid electric vehicles nowadays is one of the emerging technologies worldwide. Different countries are using this technology on their transportation, and nowadays, a lot of other countries are gradually adapting on using this kind of innovation in their transport system. Philippines is among these countries which aims to have a sustainable mobility by embracing the use of hybrid - electric vehicles but still lots of consumers are lacking awareness on this technology. Lack of information on the social, environmental, and economic potential benefits are among the main issues of Philippines consumers that really affect its uptake. The goal of this study was to evaluate the consumer’s perception and purchase intention on the transition of hybrid - electric vehicles for sustainable mobility and transportation here in the Philippines. It aimed to assess consumer awareness with hybrid - electric vehicles and its potential benefits to human beings in terms of social, environmental, and economic aspects. The study also gauged the impact of this perception on consumer’s purchase intention on hybrid - electric vehicles. These objectives were attained using the Descriptive Statistics and Correlation Analysis. Using these methods, the results revealed that majority of the consumers believed on the positive benefits of transitioning to hybrid - electric vehicles in terms of social, environmental, and economic aspects. This study also showed that these benefits have high impact on the consumer’s intention of buying or having a hybrid – electric vehicle. Electric vehicle is one of the most effective measure of decarbonizing the transport system. Furthermore, government and automotive businesses must strengthen their drive in spreading awareness of hybrid – electric vehicle’s benefits to consumers to further support country’s effort for development.
A Novel Eeg Classification Method for Quantifying Kinematic Parameters
Authors: Collins David
Published: August 2023

Abstract: In recent years, low frequency (LF) electroencephalogram (EEG) signals have been decoded to obtain kinematic trajectories with the aim of achieving closed loop natural control. However, decoded trajectories suffer variability and low correlation against the measured movement. This paper suggests that if EEG features of motor intents are directly associated with fixed points along a given range of motion, then the natural kinematic parameters can be quantified. A novel classification method is proposed to evaluate this hypothesis along with equations for obtaining the movement parameters (velocity, acceleration). Furthermore, this implies that the force of an end-effector and work done in moving the end-effector may be computed, leading to natural control of EEG-based robotic arms and neuroprostheses. Finally, expectations are that combining the proposed method with existing classification methods will increase the accuracy and scalability of brain-computer interface (BCI) applications.

Представлены результаты расчетных исследований тонального шума первой подпорной ступени турбореактивного двухконтурного двигателя с высокой степенью двухконтурности для режима работы «посадка». Исследования выполнены с помощью метода расчета тонального шума многоступенчатых турбомашин в частотной области, разработанного в ЦИАМ. Используется вариант метода, предназначенный для расчетов в нелинейной постановке, в рамках которого расчет в каждом венце проводится для нескольких межлопаточных каналов. В процессе расчета применяется разновидность метода гармонического баланса для многотоновых возмущений основанная на искусственном отображении частот. Результаты расчета сопоставлены с полученными ранее результатами расчета во временной области (также выполненного в нелинейной постановке) и с результатами эксперимента на стенде ЦИАМ. И в том, и в другом случае показано удовлетворительное соответствие между данными. Таким образом, рассматриваемый в данной работе метод расчета тонального шума в частотной области в нелинейной постановке может использоваться для предсказания тонального шума многоступенчатых турбомашин.
Strong Ground Motion of the 1923 Kanto, Japan Earthquake
Authors: Midorikawa Saburoh
Published: August 2023

The 1923 Kanto earthquake (MJ=7.9) has great significance for seismic hazard assessments of the Tokyo metropolitan area, because it caused extensive damage to the area. To deepen our understanding of the strong ground motion of the Kanto earthquake, this paper reviewed studies on its observed strong ground motion and found that 1) seismic intensity VI on the Japanese scale (IX or X on the M. M. scale) was widely distributed in an area of approximately 8,000 km2, which is equivalent of that of the 2011 M9 Tohoku earthquake, 2) strong effects of soil amplification on ground motion were suggested by the correlation of the damage distribution with surface geology, 3) the restoration of the scaled-out seismogram indicated that the ground motion at the upland of Tokyo would be roughly 50 cm/s for maximum velocity and 50 cm for maximum displacement, and 4) the ground motion in the epicentral area is unclear, but would be roughly twice or more as strong as that at Tokyo.
Charles A. Beard, Shinpei Goto, and “The Light of Western Experience”
Authors: Mammen David
Published: August 2023

Charles A. Beard, a prominent American scholar, and Shinpei Goto, Home Minister and former mayor of Tokyo, forged a close friendship in 1922–23 based on their mutual interest in the so-called scientific management approach to planning, urban management, and public administration. In New York City, Beard directed the programs of the fifteen-year-old Bureau of Municipal Research and Training School for Public Service, which fostered reform and practical improvements in public management through applied studies. Goto invited Beard to Japan to lecture, study the problems of Tokyo, and help develop the Tokyo Institute for Municipal Research which Goto established and chaired. Beard’s influence was already cemented by June 1923 when his report—later published as “The Administration and Politics of Tokyo”—was presented to Goto. Their relationship would deepen and expand after September 1, 1923 when the Great Kanto Earthquake occurred and Goto again reached out to Beard in what was likely the first telegram out of the country after the disaster, asking Beard to return to help. Beard returned for six weeks, during which the general outlines of reconstruction were developed by the Reconstruction Bureau headed by Goto. Much has been written about those six weeks, about the failure of Goto to win support for his grandest plans, and about the role Beard may have played in helping to shape both Goto’s thinking and the actual, scaled down plans that were approved and built. On the occasion of the 100th anniversary of the Great Kanto Earthquake, it is worth revisiting the literature and looking more closely at Beard’s contributions.

Authors: Wilkins Justin , Barkman Alexandria , Meltel Alexi , Suedel Burton , Richmond Robert
Published: August 2023

Sedimentation can occur near a dredge operation in pulses over days, and potentially impact coral reefs occurring in close proximity. To improve the ability to predict the effects of dredging on corals, the effects of sedimentation in two 18-day experiments were studied for three common coral species representing different morphologies. In a laboratory setting, coral fragments were exposed to four sedimentation concentrations dosed every four days ranging from 0 to 60 mg cm-2. Separate experiments were performed in series, once with fine grain sediment and repeated with a coarse grain sediment. A 30-day sediment free observation period followed each experiment. Coral responses were measured throughout the experiment and at the end of the 18-day exposure and 30-day sediment free observation period. Photosynthetic yield, lipid ratios, tissue color, tissue loss, growth, and sediment cover varied among the treatment groups. All coral species were minimally affected when sediment concentrations were at or below 6 mg cm-2. P. meandrina and P. lobata experienced the most sediment coverage and tissue loss when exposed to sediment concentrations >30 mg cm-2 for either sediment. M. capitata experienced no sediment coverage or tissue loss when exposed to either sediment, but a reduction in photosynthetic yield at 60 mg cm-2 fine grain sediment was observed. During the 30-day post-exposure sediment free observation period, P. meandrina tissue loss continued, P. lobata nearly completely regrew lost tissue, while M. capitata showed no lingering effects. This study improves the US Army Corps of Engineers (USACE) ability to estimate the impacts of dredging on coral reefs.

Published: August 2023

Objective: The study provided live music intervention featuring personalized selections for a group of dementia patients at a continuing care community. The study assessed the effectiveness of this intervention in reducing the frequency of expressions of agitation and depression in the patients. Design: Within group design (pre and post-test).
Setting and Participants: The study took place in a continuing care community for adults with dementia behaviors over the age of 60. The research population consisted of individuals either diagnosed with dementia or had exhibited symptoms of dementia. Intervention: The study was done over a 13-week period. Live weekly personalized music interventions were provided by college-aged musicians.
Measurement: The participants' depression and agitation levels were measured by the PHQ-9 (DEPRESSION SCALE) and CMAI (Cohen-Mansfield Agitation Inventory). The data was filled out by the participants’ primary caregivers and then collected after every two music interventions.
Results: Data collected after the final (W13) personalized music intervention demonstrated that overall, all patient groups experienced a significant decrease in depressive behavior (p = 0.001). Within patients, higher attendance during personalized music intervention was also shown to be effective in contributing to reduced depressive behavior (p = 0.0016). Within all patient groups, no significant data could be drawn from the effects of personalized music intervention on agitated behavior.
Conclusion: Personalized music intervention is effective in reducing depressive behavior in dementia patients. Further investigation of the effects of personalized music intervention on symptoms of agitation within dementia patients is still necessary.

Published: August 2023

Pastoral-based dairy production systems in northern and eastern Sri Lanka have completely been destructed during the thirty-year-long civil war. Lack of current scientific information about these systems has restricted the planning and implementation of post-war dairy development programmes in the region. Therefore, the aim of this study was to explore the current situation of pastoral-based dairy production systems in the Northern Area of Sri Lanka. Data were collected from a survey of 100 dairy farmers, key informant interviews, and observations. Feed and water samples were also collected for laboratory analysis. According to the survey, extensive management system (78%) is predominant in the region followed by semi-intensive (16%) and intensive (6%) systems. Indigenous crosses of cattle were the main breed in extensive and semi-intensive systems. Sahiwal crosses were reared in the intensive system. Cattle in the extensive system fed on poor-quality forages available on roadsides, common lands, uncultivated paddy fields and marginal forest lands. Forages were supplemented with concentrate feed ingredients, vitamin and mineral mixture in the intensive management system. Farmers in the semi-intensive system used similar feeding sources to that of extensive system and concentrate feed ingredients in addition. Irrigation canals, village tanks and concrete ponds were the main sources of drinking water in the extensive system while cattle under semi-intensive system depended on water available on concrete ponds, village tanks and dug wells. Farmers in the intensive systems used the water in dug wells. The water available in the above sources was poor in quality with a high amount of dissolved solids and high electrical conductivity according to the laboratory analysis. The daily milk yield per cow was significantly higher in the intensive system (2.23 L/cow/day ± 0.28) compared to extensive (1.12 L/cow/day ± 0.08) and semi-intensive (0.90 L/cow/day ± 0.19) systems. Farmers sell their milk to village collectors or collecting centres belong to Milco (a government milk processor) which is the only buyer of milk in the region. According to the SWOT analysis of all three systems, low productivity of cows, limited availability of grazing lands during the paddy cultivation season, low availability and poor quality of water, theft and wild animal attacks were found to be the biggest challenges encountered by the farmers. Programmes need to be targeted enhancing the quality of herds and availability of pasture and fodder to improve dairy production systems in the region to support rebuilding the livelihoods of war affected families.

Enhanced phosphorus management, geared towards sustainability, is imperative due to its indispensability for all life forms and its close association with water bodies’ eutrophication, primarily stemming from anthropogenic activities. In response to this concern, innovative technologies rooted in the circular economy are emerging, to remove and recover this vital nutrient to global food production. This research undertakes an evaluation of the dead-end filtration performance of a mixed matrix membrane composed of modified bentonite (MB) and polyvinylidene fluoride (PVDF) for efficient phosphorus removal from water media. The MB:PVDF membrane exhibited higher permeability and surface roughness compared to the pristine membrane, showcasing an adsorption capacity (Q) of 23.2 mgP.m-2. Increasing the adsorbent concentration resulted in a higher removal capacity (from 16.9 mgP.m-2 to 23.2 mgP.m-2) and increased solution flux (from 0.5 L.m-2.h-1 to 16.5 L.m-2.h-1) through the membrane. The initial phosphorus concentration demonstrates a positive correlation with the adsorption capacity of the material, while the system pressure positively influences the observed flux. Conversely, the presence of humic acid exerts an adverse impact on both factors. Additionally, the primary mechanism involved in the adsorption process is identified as the formation of inner-sphere complexes.

Objective Sleep disorder is the most common complaint of patients with schizophrenia, which can not only lead to poor prognosis and low survival rate but also aggressive behaviour, posing a significant threat to social security and stability. The aim of this study is to explore the mediating role of depression in the relationship between sleep disorders and aggressive behaviour in people with schizophrenia living in the community, as well as the regulatory role of family intimacy and adaptability. These findings, in turn, may provide a theoretical basis and constructive suggestions for resolving the physical and mental health problems of these patients.Method A convenience sampling method was used to select schizophrenia patients from Pengzhou City, China, for follow-up, and a survey was conducted on the Questionnaire Star platform. The survey included questions about general demographic data and disease-related questionnaires: the Pittsburgh Sleep Quality Index (PSQI), the Modified Over Aggression Scale (MOAS) revised Chinese version, the Self-Rating Depression Scale (SDS), and the Family Adaptability and Cohesion Scale, Second Edition. FACES-II and SPSS 21.0 were used to organize and analyse the data.Results A total of 818 schizophrenia patients living in the community participated in the survey, and 785 valid questionnaires were ultimately collected for a response rate of 95.97%. The results of multivariate analysis indicate that gender, psychiatric medication use, outpatient follow-up, and sleep disorders are the factors influencing aggressive behaviour. Depression played a partial mediating role between sleep disorders and aggressive behaviour, and the indirect effect size value was 0.043 (57.33% of the total). Sleep disorders and family intimacy (β=-0.009, P < 0.01) and adaptability (β=-0.145, P < 0.001) can significantly predict depression.Conclusion 1. The incidence of aggressive behaviour and sleep disorders in patients with schizophrenia living in the community is low. 2. Depression plays a partial mediating role in the relationship between sleep disorders and aggressive behaviour. 3. Family intimacy and adaptability play a regulatory role between depression and sleep disorders.

Purpose
To perform an extensive investigation of the clinical features and long-term complications among the n = 134 adults and children with nucleic acid amplification test (NAAT) verified SARS-CoV-2-infection in the immunologically naïve population of Ulvik, Norway, during the single variant B.1.1.7 outbreak in late January through February 2021.
Methods
Every infected person regardless of whether symptoms of COVID-19 were present was invited to answer a web-based questionnaire at two- and seven months after testing positive. The period from initial infection to the first questionnaire was assessed retrospectively, and the time points at two- and seven months were assessed prospectively.
Results
A total of 87 of 134 (65%) NAAT-positive persons answered the first questionnaire, of which 35/87 (40%) were children, and 74 of 87 (85%) answered the second questionnaire. Children experienced symptoms less often than adults during the acute phase of infection (51% (18/35) versus 81% (42/52) (p = .004)). At two-months follow-up 88% (53/60) of participants with symptoms during the acute phase, including all children, reported no longer having symptoms. Among those with persisting symptoms at seven months, fatigue (18/25) and insomnia (16/24) were common.
Conclusion
In an immunologically naïve population infected with the SARS-CoV-2 B.1.1.7 variant, the clinical features of acute phase symptoms were similar to previous studies. Children underwent asymptomatic infection more often than adults, and adults more often experienced persisting symptoms. Insomnia and fatigue were common complaints among those with persisting symptoms seven months after infection.
Mendelian Randomization analyses between body mass index and atrioventricular block: underweight is a risky state

Background
Atrioventricular block (AVB) is a prevalent cardiac conduction disorder among the elderly population. Body mass index (BMI) is a crucial indicator of nutritional status, and underweight individuals face elevated risks of various health conditions, including cardiovascular diseases. Previous observational studies have reported an association between BMI and AVB risk, but causality remains uncertain due to potential confounding factors and reverse causation.
Methods
To investigate the causal relationship between BMI and AVB risk, we employed a Two-Sample Mendelian Randomization (TSMR) approach, utilizing data from two independent Genome-Wide Association Studies (GWAS). We obtained genetic variants associated with BMI from a meta-analysis comprising 694,649 individuals of European descent and AVB summary statistics from the FinnGen project, including 5536 AVB cases and 286109 controls of European ancestry. We selected instrumental variables (IVs) for BMI based on strict criteria and validated their strength through F statistics. In our study, Inverse Variance Weighted (IVW), Weighted Median, MR-Egger, Weighted Mode, and Simple Mode were used for causal relationship analysis.
Results
Our TSMR analysis, using the inverse variance weighted (IVW) method, revealed a significant negative causal effect of BMI on AVB risk. One standard deviation genetically determined rise in BMI was associated with a 38% reduction in relative AVB risk (N = 373 SNPs; OR = 0.62; 95% CI = 0.53–0.73; p = 3.74 × 10 − 9). Supplementary analyses using MR-Egger regression, weighted mode, simple mode, and weighted median provided consistent support for these findings.
Conclusions
Our study supports the genetic causality between lower BMI and increased AVB risk, indicating that maintaining a healthy BMI is crucial, especially for individuals who are underweight. These findings may help unravel the underlying mechanisms linking BMI and AVB, potentially contributing to improved prevention and management strategies for this cardiac disorder.

Aluminum lithium 2060 alloy is an ideal structural material for aeronautical components. Friction stir welding (FSW) of two-millimeter-thick 2060 Al-Li alloy plates under a welding speed of 600 mm/min and rotation speed of 400 rpm flourishes as better joining process. During FSW process, the three zones of weld nugget zone (WNZ), thermally mechanical affected zone (TMAZ) heat affected zone and base metal (BM) on the weld transverse cross section are classified caused by tool stirring and axial force in friction stir welded joints. BM shows that the microstructure is characterized by lamellar structures of the lath-shaped α phase arranged along the rolling direction. The WNZ, with fine and equiaxed grains, is a typical feature of the recrystallized structures resulted from dynamic recrystallization due to severe plastic deformation and high temperature. The TMAZ, a transition zone surrounding the weld nugget experiences a combined action of friction heating and high bending. The equipment was designed and fabricated to investigate the stress corrosion cracking behavior in simulated environment. Electrochemical evolution of FSW Al-Li 2060 alloy in 3.5wt.% NaCl solution and performed open circuit potential, electrochemical impedance spectroscopy and cyclic polarization in unloaded condition and with applied load of 500, 1000 in specific intervals (1, 24, 48) hours. Results show that poor corrosion resistance in unloaded condition and decrease with the specific time interval. Results show that corrosion rate in unloaded 102, for 500 g load is 7.5 and for 1000g load is 48.76 in millimeter per year (mm/y).

Purpose
Inflammatory bowel disease (IBD) occurring following allogenic stem cell transplantation (aSCT) is a very rare condition. The underlying pathogenesis is poorly defined. There is currently no systematic effort to exclude loss- or gain-of-function mutations in immune-related genes in stemcell donors.
Methods
Whole exome sequencing of hematopoietic cell-intrinsic, donor-derived vs. skin-derived germline DNA was performed in an index patient with post-aSCT IBD. Expression of the immune checkpoint protein TIM-3 and T cell-edrived cytokines/chemokines was assessed in in vitro activated patient-derived T cells by flow-cytometry and by performing immune-histology on sections from inflamed vs. non-inflamed intestinal tissue.
Results
We have molecularly characterized a patient who developed fulminant inflammatory bowel disease following aSCT with stable 100% donor-derived hematopoiesis. A pathogenic c.A291G; p.I97M HAVCR2 mutation encoding the immune checkpoint protein TIM-3 was identified in the patient’s blood-derived DNA, while being absent in DNA derived from the skin. TIM-3 expression was much decreased in in vitro activated patient-derived T cells, while effector cytokines and Foxp3 expression were preserved. TIM-3 expression was barely detectable in the patient’s intestinal mucosa, while being detected unambiguously in inflamed and non-inflamed colon from unrelated individuals.
Conclusion
We report the first case of acquired, ‘transplanted’ insufficiency of the regulatory TIM-3 checkpoint linked to post-aSCT IBD.

We examined two variants of turnip mosaic virus (TuMV) KJS 5 and KJS 5 − 1, the polyproteins of which differ by only a single amino acid residue, located in HC-Pro motif CDNQLD. When KJS 5 and KJS 5 − 1 were inoculated to Nicotiana benthamiana and Raphanus sativus differential symptom severity were observed in each host. To complement these results, smGFP and the variant HC-Pros were co-expressed in N. benthamiana leaves by agro-infiltration. Real-time qPCR analysis showed that the relative expression levels of smGFP differed. This shows that a single amino acid substitution affects both symptom severity and RNA silencing suppression efficiency.
