Konstruksi Pasal 33 UUD 1945 dalam Menangkal Pengaruh Sistem Kapitalisme di Indonesia
Authors: Fadhli Ashabul , Zurwanty Recy Harviani , Sari Vivi Puspita
Published: June 2023

It is undeniable that the grip of capitalism has been rooted in Indonesia since colonialism, independence to the development of today's globalization. The roots of capitalism in Indonesia have hindered the achievement of the objectives of implementing independence in terms of improving the economic welfare of the people. This can be seen in the Investment Law with its transfer and repatriation system which makes it easier for foreign companies to transfer their profits abroad, the plantation sector which is more profitable for large companies, the retail market which has begun to enter rural areas and the principle of developmentalism which allows large debts to international institutions. In order to strengthen the goal of independence, and to avoid the influence of capitalism which can undermine the stability of the national economy and social welfare, a deeper study of Article 33 of the 1945 Constitution is needed. This research departs from normative legal research. The approach used is a legal-statutory approach and a historical approach. The results of this study prove that the 1945 Constitution has a very strong influence in determining the national economic system. Conducting a review of Article 33 of the 1945 Constitution is important so that the State with its powers in realizing the greatest prosperity and welfare of society.

Published: June 2023

Nikah misyar merupakan nikah yang belum lazim pada saat ini, dimana istri melepaskan sebagian haknya yaitu untuk tidak menerima nafkah dari suaminya dan hanya menuntut nafkah batiniyah saja, Yusuf Al-Qardawi membukukan secara tersendiri perihal nikah misyar, nikah misyar sendiri saat ini masih jarang diperbincangkan oleh ulama di Indonesia karena masih tergolong degan nikah model baru bagaimana pandangan ulama MUI terhadap nikah misyar. Penelitian ini dilakukan dengan metode field research (penelitian lapangan), pengambilan data dalam penelitian ini di peroleh dengan menggunakan metode wawancara. Nikah misyar Yusuf Al-Qardawi menurut ulama MUI Kota Ponorogo dapat di kategorikan menjadi 2 ada yang membolehkan secara mutlak juga ada yang membolehkan dengan syarat, menurut Ulama MUI Ponorogo ada yang memperboleh kan karena pernikahan ini secara hukum memenuhi syarat dan rukun pernikahan, dan suatu kebolehan jika sang istri merelakan sebagian haknya yaitu nafkah lahiriyah dan hanya menuntut nafkah batiniyah, hal tersebut tidak membuat batalnya suatu pernikahan, sedangkan menurut Ulama MUI Ponorogo yang memperbolehkan dengan syarat  walaupun baik rukun dan syaratnya sudah terpenuhi kita juga perlu mengetahui tujuan dan motif dilaksanakannya nikah misyar apakah demi kemaslahatan ataukah demi kemafsadatan, karena pada hakikatnya pernikahan adalah untuk mencapai sakinah, mawaddah, war-rahmah, dan nafkah adalah termasuk di dalamnya.

Introduction

Social determinants of health (SDH) may influence children’s weight status. Our objective was to examine relationships between SDH and preschoolers’ weight status.

Methods

This retrospective cohort study included 169 465 children (aged 4–6 years) with anthropometric measurements taken at immunization visits from 2009 to 2017 in Edmonton and Calgary, Canada. Children were categorized by weight status based on WHO criteria. Maternal data were linked to child data. The Pampalon Material and Social Deprivation Indexes were used to assess deprivation. We used multinomial logistic regression to generate relative risk ratios (RRRs) to examine associations between ethnicity, maternal immigrant status, neighbourhood-level household income, urban/ rural residence and material and social deprivation with child weight status.

Results

Children of Chinese ethnicity were less likely than those in the General Population to have overweight (RRR = 0.64, 95% CI: 0.61–0.69) and obesity (RRR = 0.51, 0.42–0.62). Children of South Asian ethnicity were more likely than those in the General Population to have underweight (RRR = 4.14, 3.54–4.84) and more likely to have obesity (RRR = 1.39, 1.22–1.60). Children with maternal immigrant status were less likely than those without maternal immigrant status to have underweight (RRR = 0.72, 0.63–0.82) and obesity (RRR = 0.71, 0.66–0.77). Children were less likely to have overweight (RRR = 0.95, 0.94–0.95) and obesity (RRR = 0.88, 0.86–0.90) for every CAD 10 000 increase in income. Relative to the least deprived quintile, children in the most materially deprived quintile were more likely to have underweight (RRR = 1.36, 1.13–1.62), overweight (RRR = 1.52, 1.46–1.58) and obesity (RRR = 2.83, 2.54–3.15). Relative to the least deprived quintile, children in the most socially deprived quintile were more likely to have overweight (RRR = 1.21, 1.17–1.26) and obesity (RRR = 1.40, 1.26–1.56). All results are significant to p $lt; 0.001.

Conclusion

Our findings suggest the need for interventions and policies to address SDH in preschoolers to optimize their weight and health.

Degenerative diseases occurred due to several risk factors that are directly related to inflammationwhich affected several diseases such as coronary heart disease (CHD) and diabetes. One of theinflammatory causative agents is leukotrienes produced by the lipoxygenase enzyme (LOX) so thatit takes anti-inflammatory drugs made from herbal plants. Red betel leaf (Piper crocatum) potentiallyinhibited the lipoxygenase enzyme because it contains potential phytochemical compounds suchas alkaloids, flavonoids, eugenol, saponins, and tannins. This research aimed to test the inhibitionof active compounds from extract and fractions of red betel leaves that have the best inhibition forlipoxygenase enzymes causing malondialdehyde formed through molecular docking simulations. Thisresearch used lipoxygenase enzyme as receptor (PRB code: 4NRE), C8E as natural ligand and activecompound from extract and fractions of red betel leaves as a ligand. The highest inhibition regarded toNandrolone phenylpropionate and Sofalcone ligand with -10.4 kcal/mol and -9.1 kcal/mol of affinityenergy. Amino acid residues that played a role in ligand and receptor interaction were HIS373 andHIS378. The receptor structure with the best ligands was declared stable based on molecular dynamicssimulations.

Published: June 2023

The burnout syndrome may affect academic achievement, but research on burnout and academic success of medical students is sparse. This research aimed to estimate the prevalence of high risk of burnout in students of medicine and to investigate its association with academic performance. It included 760 full-time medical students who completed the survey (response rate = 90.9 %). A significant independent predictor for high burnout risk in students with lower grade point average (GPA) was male gender (adjusted OR=2.44; 95 % CI=1.14–5.23; P=0.022). Among students with higher GPA, high burnout risk was associated with the use of sedatives (adjusted OR=6.44; 95 % CI=1.80–22.99; P=0.004).

Authors: Hryniewicz Waleria , Strużycka Izabella
Published: June 2023

Introduction of antibiotics into clinical practice is considered as a turning point in medicine resulting in saving millions of lives and allowing for the development of new fields of medicine such as transplantology, neonatology, hematology and many others. From the very beginning, this success was accompanied by the emergence of antibiotic resistant strains with its continuous rise. Overuse and misuse of antibiotics in medicine, veterinary practice and animal and plant production are the main reasons the resistance has emerged. Presently, an increase in isolation of multidrug resistant (MDR), excessively resistant (XDR) and pandrug resistant (PDR) bacteria is being observed worldwide in the most common human etiologic bacterial agents . As examples of rapid evolution of resistance, S. aureus and Enterobacterales producing extended-spectrum beta-lactamases are presented. Some initiatives of WHO and EU aiming to tackle antibiotic resistance are also discussed.

The objective of this review to summarize the current status of information about the Alkhumra hemorrhagic fever caused by Alkhumra hemorrhagic fever virus an Arboviral infection. This virus was identified in Alkhumra district of Jeddah, Saudi Arabia in 1995 from a butcher patient. The infected individual develops symptoms febrile flu-like illness, hemorrhagic manifestations and less like encephalitis. Several cases have been reported from various locations of Saudi Arabia and a few from Egypt and is further expanding in tropical and subtropical regions of Western Asia. The virus is transmitted to human by direct contact to animal, raw meat, and biproducts as well as either tick or mosquito bites. Based on the recent status, a great concern of public health was raised with the AHFV epidemics and infection. Currently, there is no effective vaccine and antiviral therapeutics against AHFV. So, there is an urgent need to design and develop an effective preventive measure using interdisciplinary approach. This review will provide the status of research work based on the latest published information about AHFV. The provided information will be highly useful to design the effective preventive measures to control the disease in the Kingdom of Saudi Arabia.

Published: June 2023

Viral pathogens are major concern nowadays. Bacterial CRISPR/Cas systems help in defending the host body against different pathogens including viruses too. This system contains restriction enzymes that introduce dsDNA breaks on target site to make the virus non-functional by damaging its genes. Coronavirus, HIV and Herpes viruses are causing mortality all around the world. To control the spread of disease, early detection and treatment is required. CRISPR system due to its high efficiency provides a platform to restrict the viral entry into host cell, viral genome editing and eliminate the latent infections. In this review, the CRISPR strategies against three major viral diseases are put under consideration: Coronavirus, Acquired Immunodeficiency Syndrome and Herpesvirus associated diseases. Three CRISPR/Cas systems have been discussed including CRISPR/Cas12, CRISPR/Cas9 and CRISPR/Cas13 that are used against the above listed viruses.
The Occurrence of Methicillin-Resistant Staphylococcus Aureus (MRSA) Around the World and Antibiotic Therapy for Selected Infections Caused By MRSA
Authors: Wierzchowska Kamila
Published: June 2023

Staphylococcus aureus is a Gram-positive bacterium, which can cause serious bacterial infections in humans. It constitutes an important etiological factor of many diseases, for instance, soft tissue and skin infections (including skin boils and abscesses), as well as life-threatening necrotizing pneumonia or toxic shock syndrome. It is estimated that about 25–30% of people are carriers of S. aureus mainly in the anterior nostrils. A smaller percentage of people are carriers of methicillin-resistant S. aureus (MRSA). In accordance with its definition, methicillin-resistant S. aureus is resistant to almost all β-lactam antibiotics. This phenomenon is mainly caused by the presence of penicillin-binding protein in the cell wall – PBP2a, which is the product of the mecA gene, which is part of the complex called SCCmec (staphylococcal cassette chromosome mec). Methicillin-resistant S. aureus (MRSA) results in endemic in hospitals around the world and are one of the leading causes of morbidity and mortality in society. Infections initiated by hospital strains of MRSA (health care-associated MRSA, HA-MRSA) concern mainly immunocompromised patients after surgery. In addition, there are populations of acommunity-associated MRSA (CA-MRSA) strains and populations of livestock-associated MRSA (LA-MRSA) strains. The treatment of infections with MRSA etiology, after exhausting the possibilities of standard antibiotic therapy with the use of i.e. vancomycin, is based on treatment with new-generation antibiotics, such as dalbavacin.
Beginner-Coaches and Connectivity of Knowledge: Real-World Coaching and Self-Reported Importance of Prior Playing Experience
Authors: Crisp Philippe , Hamblin May
Published: June 2023

In what amounts to essentially being a part two to our previous work with six beginner-coaches that found noticeable benefits to reflective practice, yet a number of possible drawbacks such as time constraints and at times over-focusing on negative emotions (Hamblin & Crisp, 2022), we build upon the aims of that study that related to what beginner-coaches (in recreational sport fields) considered ideal coach learning within in-situ, practice-based contexts. Through revisiting the data of the first study (Hamblin & Crisp, 2022) and exploring an additional theme related to how the beginner-coaches identified sporting experience as a beneficial prerequisite to their own coaching practice, the present study sought to further investigate, and build upon, the findings and aspects of the first study. Continuing to explore how beginner-coaches who operate more within recreational (although still competitive) sport fields perceive in-situ, ideal learning, and continuing the same methodological approach, the present study conducted semi-structured interviews with another five beginner-coaches, adding to the six in the first study for a total of 11 participants.

Transcriptions were analysed using thematic analysis and the themes found included sporting experience, traditional learning, and the benefits of reflective practice which highlights the ways all of the beginner-coaches (within both ‘part one’ and the present study – ‘part two’) felt they learn best. Importantly, these findings showed the self-reported importance of actually coaching (‘real world’ applications) and, of particular note, what were considered by the beginner-coaches to be the significant benefits of having accrued playing experience prior to starting coaching. These findings then may well provide further evidence to uphold and develop methods of coach education in the future to facilitate learning.

Published: June 2023

Background

Cortical thickness (CT) and brain-derived neurotrophic factor (BDNF) were widely investigated in bipolar disorder (BD). Previous studies focused on the association between the volume of subcortical regions and neurotrophic factor levels.

Objective

In this study, we aimed to evaluate the association of the CT in youth with early-onset BD with BDNF levels as a potential peripheral marker of neuronal integrity.

Method

Twenty-three euthymic patients having a clinical diagnosis of BD and 17 healthy subjects as an age-matched control group with neuroimaging and blood BDNF levels were found eligible for CT measurement. A structural magnetic resonance scan (MRI) and timely blood samples were drawn.

Results

Youth with BD exhibited lower cortical thickness in caudal part of left (L) middle frontal gyrus, right (R) paracentral gyrus, triangular part of R inferior frontal gyrus, R pericalcarine region, R precentral gyrus, L precentral gyrus, R superior frontal gyrus and L superior frontal gyrus when compared to healthy controls. The effect sizes of these differences were moderate to large (d=0.67-0.98) There was a significant correlation between BDNF levels with caudal part of the R anterior cingulate gyrus (CPRACG) in adolescents with BD (r=0.49, p=0.023).

Conclusion

As a special region for mood regulation, the CT of the caudal part of the R anterior cingulate gyrus had a positive correlation with BDNF. Regarding the key role of CPRACG for affective regulation skills, our results should be replicated in future follow-up studies, investigating a predictive neuroimaging biomarker for the early-onset BD.

Satellite Collision and Fragmentation Probabilities Using Radar-Based Size and Mass Estimates
Authors: Hall Doyle T. , Baars Luis G.
Published: June 2023

Most conjunctions between Earth-orbiting satellites involve unknown objects, typically debris created by explosions or collisions. This study formulates methods to estimate probabilities of collision and fragmentation for such conjunctions, which depend on the estimated sizes and masses of the unknown objects. Analysis of radar cross-section (RCS) measurements provides estimated sizes, found to be accurate at the 90% confidence level to within a factor of 0.59 for potential underestimations and to within a factor of 3.1 for potential overestimations. For satellites that experience measurable atmospheric drag orbital perturbations, combining RCS data with orbit determination ballistic coefficients provides mass estimates accurate to within factors of 0.47 to 10.9 at the 90% confidence level. For satellites with perigee altitudes above 450 km, combining RCS data with solar radiation pressure coefficients provides mass estimates accurate to within factors of 0.44 to 5.6 at 90% confidence. The collision and fragmentation risk assessment formulation accounts for these size and mass estimation uncertainties. Specifically, conjunction collision probabilities formulated as statistically expected values account for the RCS-based size estimation uncertainties. Fragmentation probabilities, which measure the likelihood of producing more than a threshold number of collision fragments, account for both size and mass estimation uncertainties.
Machine-Learning Based Rotor Fault Diagnosis in a Multicopter with Strain Data
Authors: Dutta Airin , Niemiec Robert , Kopsaftopoulos Fotis , Gandhi Farhan
Published: June 2023

An innovative machine-learning-based probabilistic framework for online rotor fault diagnosis in multicopters is presented. The proposed scheme employs in-flight out-of-plane strain measurements at each of the multicopter booms to detect, identify, and quantify rotor faults while distinguishing them from the aircraft response to random gusts. Its robust performance is demonstrated with application to a 2-foot-diam hexacopter flying under varying forward velocity and gross weight configurations, as well as atmospheric disturbances and uncertainty. The rotor fault diagnosis takes place in two steps. First, a simple perceptron classifies the aircraft’s health condition. If a rotor fault is detected it is simultaneously identified and the fault magnitude estimation step initiates. Here, linear regression models are used to predict the respective rotor degradation values with their 95% confidence intervals. The generalization capability of the method is established with several test data under unmodeled operating conditions (not used in the training phase). The proposed framework can accurately diagnose even minor rotor faults of 8% degradation while distinguishing them from aggressive gusts of up to [Formula: see text] magnitude. The maximum fault detection time is less than 0.3 s. The health state classification and the rotor fault magnitude quantification accuracy are over 99%.
Unsteady Propulsion of a Two-Dimensional Flapping Thin Airfoil in a Pulsating Stream
Authors: Sanchez-Laulhe Ernesto , Fernandez-Feria Ramon , Ollero Anibal
Published: June 2023

The cruising velocity of animals, or robotic vehicles, that use flapping wings or fins to propel themselves is not constant but oscillates around a mean value with an amplitude usually much smaller than the mean, and a frequency that typically doubles the flapping frequency. Quantifying the effect that these velocity fluctuations may have on the propulsion of a flapping and oscillating airfoil is of great relevance to properly modeling the self-propelled performance of these animals or robotic vehicles. This is the objective of the present work, where the force and moment that an oscillating stream exerts on a two-dimensional pitching and heaving airfoil are obtained analytically using the vortical impulse theory in the linear potential flow limit. The thrust force of the flapping airfoil in a pulsating stream in this limit is obtained here for the first time. The lift force and moment derived here contain new terms in relation to the pioneering work by Greenberg (1947), which are shown quantitatively unimportant. The theoretical results obtained here are compared with existing computational data for flapping foils immersed in a stream with velocity oscillating sinusoidally about a mean value.
Hemodynamic Parameters in Students with Different Thresholds of Salt Sensitivity and Type of Autonomic Tone: An Observational Cohort Study
Authors: Chastoyedova I. A.
Published: June 2023

Background. Hemodynamic parameters are interrelated with both the threshold of salt sensitivity and the type of initial autonomic tone. Available data on such relationships are insufficient. Objective — to identify the hemodynamic parameters and features in students with different thresholds of salt sensitivity and types of autonomic tone.

Methods. The study enrolled 174 second-year students of Kirov State Medical University, aged 18–23, who gave consent to the survey. The study was conducted over a period of four months and included two stages. At the first stage, all participants were evaluated for the threshold of salt sensitivity. According to the results, two groups were formed: group A — students with a normal threshold of salt sensitivity (n = 127); group B — students with a high threshold of salt sensitivity (n = 39). In the formed groups, a comparative analysis of hemodynamic parameters was carried out. At the second stage of the study, after assessing the initial autonomic tone, three groups were identified: group 1 (n = 40) — students with equilibrium of the sympathetic and parasympathetic systems (normotension); group 2 (n = 104) — students with dominating parasympathetic regulation of the heart rhythm (vagotonia); group 3 (n = 22) — students with dominating sympathetic regulation of the heart rhythm (sympathicotonia). Hemodynamic parameters were also studied in these groups. Statistical data processing was carried out using Statistica Advanced 10 for Windows RU. The differences between the comparison groups were assessed using parametric Student’s t-test and non-parametric Mann-Whitney U-test.

Results. A high threshold of salt sensitivity was revealed in 23% of students. When comparing hemodynamic parameters in the groups, it was found that students with high thresholds of salt sensitivity had significantly higher values of systolic blood pressure, diastolic blood pressure, pulse pressure and average hemodynamic pressure than students with a low threshold. Differences in hemodynamics in students may be caused by differences in the original autonomic tone. Thus, students with vagotonia, if compared to those with normotension, have significantly lower values of heart rate, cardiac minute output, double product, and circulatory efficiency ratio, but a higher value of the peripheral vascular resistance. Students with sympathicotonia have statistically higher heart rate, cardiac minute output, and double product values.

Conclusion. The assessment of hemodynamic parameters in healthy young people in relation to the threshold of salt sensitivity and the initial autonomic tone enables the risk factors for the development of hypertension to be assessed, prehypertension (high normal blood pressure) to be identified, and preventive programs aimed at reducing the number of diseases of the cardiovascular system to be developed.

Rational Design of Two-Dimensional Buckled-Hexagonal Nb2S2 Monolayer as an Efficient Anode Material for Ca-ion Batteries: A First-Principles Study
Authors: Chowdhury Somnath , Sen Prasenjit , Gupta Bikash Chandra
Published: June 2023

Presently, great attention is being paid to the search for promising anode materials for metal-ion batteries (MIBs) due to the rapid evolution of numerous modern electronic gadgets. In this investigation, we have predicted for the first time that the buckled-hexagonal Nb2S2 monolayer which may be an efficient anode material for calcium-ion batteries (CIBs). To that objective, we have explored the pristine monolayer system’s energetical, dynamical, and thermal stability. The inherent metallicity of the pristine monolayer facilitates its electrical conductivity as an electrode material. Our study also reveals the structural and electrical properties of the Ca-adsorbed Nb2S2 monolayer. It is observed that Ca-atoms prefer to get intercalated on top of the buckled hexagon of the pristine monolayer, and the metallicity of the 2D nanosheet remains preserved. In the adsorption process, Bader charge analysis is used to determine the amount of charge transfer from the Ca atom to the Nb2S2 monolayer. Furthermore, this system exhibits a high storage capacity of 1288.86 mAh/g and a moderately low diffusion energy barrier of 0.76 eV. The calculated open-circuit voltage of 0.49 V and the other results suggest that the Nb2S2 monolayer may be a potential candidate for anode material for rechargeable Ca-ion batteries.

Authors: Mitra Souvik , Zens Clara , Kupfer Stephan , Diddens Diddo
Published: June 2023

This research elucidates the intricate nature of electronic coupling values for the redox-active (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) often used in organic radical batteries (ORBs), employing a combination of classical molecular dynamics (MD) and multiconfigurational simulations, i.e., the Complete active space self-consistent field (CASSCF) methods. Our study reveals the significant influence of both distance and relative orientation of the redox pairs (TEMPO and TEMPO+) on the electronic coupling. Thus, our simulations suggest that the electronic communication between the redox centres and this the charge mobility heavily depends on both - TEMPO's intrinsic molecular properties as well as the supramolecular environment in the electrode material. Additionally, our study highlights the limitations of the frontier molecular orbital (FMO) method in this context. Our findings underscore the significance of integrating molecular dynamics and advanced electronic structure methods, like CASSCF, to garner a holistic understanding of electronic coupling for charge transfer reactions in organic electrodes.

Published: June 2023

Cobaltcarbonyl-tert-butylacetylene (CCTBA) is a conventional precursor for the selective atomic layer deposition of Co onto silica surfaces. However, the limited understanding of the deposition mechanism of such cobalt precursors curbs rational improvements on their design for increased efficiency and tuneable selectivity. The impact of using a less reactive internal alkyne to a terminal alkyne was investigated using experimental and computational methods. Electrospray-ionization mass spectrometry was used to monitor the formation of CCTBA analogs and study their gas phase decomposition pathways. Gas phase analysis show that an internal alkyne dissociates at slightly lower energies than a terminal alkyne, suggesting that an internal alkynyl ligand may be more suited to low temperature ALD. Furthermore, the less reactive internal alkyne will result in fewer carbon impurities embedded in surfaces, in particular due to its reduced reactivity with Si-H bonds on the surface of Si wafers. Computational analysis also predicts increased surface binding in the metal centers of the internal alkynyl complex.

Molecular property prediction (MPP) is a crucial task in the drug discovery pipeline, which has recently gained considerable attention thanks to advances in deep neural networks. However, recent research has revealed that deep models struggle to beat traditional non-deep ones on MPP. In this study, we benchmark 12 representative models (3 non-deep models and 9 deep models) on 14 molecule datasets. Through the most comprehensive study to date, we make the following key observations: \textbf{(\romannumeral 1)} Deep models are generally unable to outperform non-deep ones; \textbf{(\romannumeral 2)} The failure of deep models on MPP cannot be solely attributed to the small size of molecular datasets. What matters is the irregular molecule data pattern; \textbf{(\romannumeral 3)} In particular, tree models using molecular fingerprints as inputs tend to perform better than other competitors. Furthermore, we conduct extensive empirical investigations into the unique patterns of molecule data and inductive biases of various models underlying these phenomena.

Universities, due to their main functions to perform, such as teaching and training, research, and collaboration with the external community, find themselves taking on a crucial role in promoting the development of human capabilities for a sustainable world, where they act to improve and promote a culture of total social inclusion and sustainability values inside and outside their organizations. Therefore, Universities play an elective role in the process of promoting and disseminating human capabilities in the sustainability perspective, providing the tools and practices, and the knowledge and enriching the skills needed to overcome any obstacle and/or barrier that prevents the acceptance and absolute domination of a culture of inclusion in any organizational context, especially in the workplace, the respect of the nature and environment in general, the research and application of sustainable business models according to effectiveness, efficiency and equity criteria. This exploratory study aims to investigate university organizations by adopting the multiple case study methodology and using secondary data. The study provides a portrait of Italian public and private universities by highlighting their strategies and initiatives for developing human capabilities in the sustainable world following two guidelines: university as a working environment which performs for employees engagement in sustainability initiatives (presence of sustainable policies, e.g., policies for supporting categories of workers with disabilities, environmental solutions, their own business organizational models, disability management policies, presence of women in governance bodies, work life balance policies, etc.); university as a higher education institution (dedicated training courses, active projects, courses on disability management, courses on sustainability issues, etc.).

Unmanned aerial vehicles (UAVs) with vertical take-off and landing (VTOL) are known as drones. The World Health Organisation estimates that there are millions of chemical cases each year. More than one large integer death is caused year by human handling and use of pesticides, mainly in developing countries. In addition to cancer, endocrine disruption, issues with reproduction and craniums from chemical exposure, respiratory illnesses, allergies, and hypersensitivity are among the detrimental effects of pesticides on human health. Other insecticides may cause inflammation of the skin and eyes. There are other pesticides with highly dangerous poisons. Other pesticides also have an effect on the body's internal secretions and systems. Low exposure levels during spraying may be harmful to your health. A wide range of health effects on the body brought on by chemical exposure include changed or uncontrollable mood, behavior, loss of coordination, slower response times, decreased eye sight, and state of mind. To save time and labour, crop fertilizer is sprayed using a drone. The primary goal of this project is to design a framework for the drone that sprays fertiliser over farms. Include a description of the creation and design of the quadcopter system's spaying mechanism.

Today, humans live in the "era of the cloud," where you can store numerous resources for later use and exploitation. However, there is a security concern with uploading private or confidential data to a public cloud. Additionally, building a typical cloud storage system would be expensive and requires extensive hardware administration, making it unaffordable for individuals, SOHOs, and small businesses. To establish their own cloud, they require an affordable but reliable option. Therefore less-expensive, adaptable, and recoverable private cloud storage system utilising NAS is suggested in this work. Migration and cell recovery, two key methods for improving adaptability and recoverability, are described, and assessed.
Predictive diagnostics of RBMK reactor flowmeters

At the moment, there are 8 rectors of the RBMK type in operation. The safety of their operation is ensured by monitoring devices for key indicators. In this article, the main attention is paid to the control of the coolant flow through the fuel channel, carried out with the help of ball flow meters of the STORM-32M and STORM-8A types. During operation, there is a gradual wear of the raceway and the ball, which leads to the appearance of a negative error in the device, in other words, the readings become underestimated. In this regard, as well as due to the widespread use of ball flowmeters at nuclear power plants, the task of diagnosing the state of flowmeters is urgent. One of the approaches to determining the flow rate of the coolant is an approach based on the measurement and use of information about the activity of the coolant by the tightness control system of the fuel element shells (SKGO). The use of this radiation approach to control the flow of coolant has its advantages and difficulties. The advantage is that real experimental information about the presence of a coolant in the fuel channel is involved, and the difficulties are associated with receiving and processing the signals of the SCGO in real time and, consequently, with low efficiency of solving the problem. In this paper, we propose a method for predictive diagnostics of the flow meter condition using the design features of the multiple forced circulation circuit (CMPC) of the reactor. The adaptive parameter of the  model was selected as a diagnostic parameter. Studies have shown that the increase in time variance in experimental flow values has a clear effect on the selected diagnostic feature , as a result of which it can be said that the observation of this kind of variance change in experimental data can serve as a sign of a malfunction of the flow meter.

This paper shows the results of experiments to study the effect of the auxiliary voltage with frequency fi= 40000Hz on the stability of arc discharge at the limit mode of the welding process with single, coated electrodes. This effective method of connecting rolled and prefabricated elements of metal structures has found widespread use in their installation, manufacture and repair in the construction of various facilities: industrial and civil purposes, thermal and nuclear power facilities for responsible purposes. In this regard, the increase in the quality and technological, strength parameters of welds, the productivity of the manufacturing metal structure process, is largely associated with welding modes and an increase in the stability of arc discharge as an important element of the system: "power source-arc-welding tub-product." Improving the performance of the welding process under consideration is particularly important under mounting conditions in conjunction with its stability is an important task on the agenda. When performing the study, the following criteria and their values   regarding the stability of the welding arc were taken into account, such as: lexpl - rupture length in mm, coefficients of variation: KV(Iwd) - welding current, KV(Uwd) - voltage, qt - constant time, as well as their numerical values were obtained. The obtained numerical values of the above criteria were obtained based on the analysis of graphs (oscillograms) of the dependence of the electric current (Iwd, A) and the voltage (Uwd, V) of the arc on the time of the process duration (t, sec). The obtained results of the analysis indicate an increase in stability, a decrease in inertia of the deviation of the resistance (conductivity) of the welding arc when the auxiliary voltage is applied with a frequency of fi = 40000Hz at the limit mode of welding with coated electrodes.

A method of electrophysical chromatography was proposed to visualize the results of electrical non-destructive testing for the first time. Surface potentiograms usually used to represent the results of scanning contact potentiometry are replaced by volumetric images of structural inhomogeneities. The alternative has obvious advantages as useful additional information can drastically change the results of testing which is demonstrated by the example of a weld overlay. Methodological recommendations for constructing volumetric images of defects are formulated and implemented. The causes of self-shielding of structural inhomogeneities at different levels of fixation which are due to the mutual spatial overlap of microregions emitting waves of elastic stresses are discussed. The biggest problems in identifying defects for NDT are their complete or partial screening. The electrophysical chromatography method requires at least one experimental array obtained from the following measurements: double scanning of the surfaces of the test object; double simultaneous scanning of the surfaces of the test object; double simultaneous scanning of the surfaces of the test object using a radiation synchronizer in time or frequency. In the case of scanning along one (external or internal) surface, the coordinates of defects are determined from the corresponding cross sections and the calculated values of their depth using frequency and time-frequency analysis
