Published: August 2022

Abstract: Urban India generates tones of wastes annually. Our country faces major challenges related with waste management. Conventional garbage collection is not efficient since authorities are not notified until waste bin is full, and this leads to overflow of waste material. Efficient way of waste disposal and collection of disposed garbage is crucial for a sustainable and clean India. This paper presents smart waste management using IoT based waste bin for collection and monitoring level of waste inside bin. system is applied using two ultrasonic sensors which is being controlled by Node MCU. One of ultrasonic sensor detects level of waste in bin and or detects person approaching bin to dispose waste. This detection helps in automatic opening and closing of lid. Servo motor is connected to lid which assists action of closing and opening of lid. In this system, level of waste in bin will be sent to concerned authorities. IoT data is kept and observed using Blynk app. offered system is reliable, cost effective and can be implemented.

Authors: Panwar Dr. Tulsi
Published: August 2022

Abstract: Power generation from a solar photovoltaic system is one of the glowing research fields these days, even governments are also planning toward installation and production of power generation from renewable energy sources because in the future its feasibility and crisis of conventional energy sources will increase. Further government liberalization and technical developments vitalize the use of renewable sources for electricity generation in terms of solar power. In any power production plant, improvement in the efficiency of the plant is a big and important issue. After installing the solar power plant, it is very urgent to get maximum performance from them. With all other factors, the tilt angle and azimuth angle affect the efficiency of the plant. Thus, it is very important to orient the solar modules at optimum tilt angle and azimuth angle for any given location because they are most efficient when they are perpendicular to the sun's rays. A comparison study was executed to achieve the power variation and dust deposition with different tilt angle in natural environment of Ajmer. Powers generated by solar cells over study period are in range of 5.10W and 3.0W. It is evident that Solar module tilted at 260 generate higher power than Solar module tilted at 00 tilted module, followed by Solar module tilted at 450

Abstract: The emerging era is energy demanding and there is a drastic need to shift to more eco-friendly methods for power generation. The non-renewable resources generate 86% of the world's power. Around the world, coal and gas power plants are shutting down due to lack of fuel. With more and more industries and governments joining the Green Movement, the demand for cost effective renewable energy has surged. Solar power can be easily harnessed as compared to other eco-friendly methods, using solar panels and the conventional process of converting solar energy to electrical energy. Even though solar power is used in domestic as well as industrial applications, it is still a long way from making an impact on environmental change. Since solar panels can only be utilized up to their full potential in clear sky and sunny conditions, its usage is affected by geographic location. However, even in conditions of optimal usage, it's not used up to its full potential. As all solar panels are fixed due sunny side, they receive direct sunlight only for half a day. During the other half, the sun is behind the panels and hence, the power generation drops steadily. To rectify this, we introduce the principle used by sunflowers. Sunflowers intake energy by following the sun from sunrise till sunset. Using the same concept, we make the panels follow the sun resulting in significant increase in energy production. We take images of the sun throughout the day, using image processing make sure that the sun is directly incident to the panels, follow this procedure till sunset. This method makes sure that even in conditions of slight to moderate overcast weather, the sun will be directly incident on panels, such is the power of image processing. The status of the device as well as energy generated can be easily visualized using the mobile application provided. The system can further be made cost effective by modifying the existing panels. The concept is simple yet very efficient, robust and scalable. This method can be used for domestic as well as industrial applications. In optimal conditions, this method can generate up to 40% more energy than a conventional solar panel system of the same size. In conclusion, just by learning from nature, using only a gearbox and controller in addition to panels, we can generate significantly more electricity. In addition to this method, using most efficient solar panels that give maximum power output even in overcast conditions can further increase power output.
A Comparative Analysis of Various Spatial Modulation Techniques

Published: August 2022

Abstract: Spatial modulation (SM) is an emerging digital modulation technology that fulfills the requirement of higher Spectra efficiency and high energy efficiency and has a very wide range of applications. The concept used in Spatial Modulation can further be extended to other domains such as frequency, time, angle or even across multiple domains. The basic idea behind SM is to convey extra information with the ON/OFF states of transmitting antennas. In single RF Spatial Modulation, only one antenna is activated at a time. Therefore, it requires only one RF chain which reduces the cost as compared to MIMO [1] system.

Published: August 2022

The vaccination against SARS-CoV-2 has been recognized as a priority strategy to safeguard public health. However, disparities in productive, acquisitive and distributional capacity have led to delays in immunization, particularly in low- and middle-income countries. Consequently, global coverage is expected to achieve herd immunity against COVID-19 by 2023 or 2024, although with highly variable coverage percentages among countries. In Latin America, immunization against COVID-19 faces different challenges to achieve herd immunity. To date (February 6, 2022), the countries that had several doses needed to immunize their populations with at least two doses (number of doses between population) were Peru (520.7%), Chile (458.4%), Argentina (298.0%), Brazil (236.6%), Bolivia (206.0%) and Uruguay (unconfirmed doses). On the other hand, Uruguay (210.7%) and Chile (238.3%) have applied twice as many doses as their populations. Argentina (194.3%), Brazil (173.6%), Ecuador (170.3%), Peru (170.3%), Costa Rica (161.1%), and Panama (153.5%) are on the way to achieving this goal. In addition, Latin American countries also showed an insufficient distribution of vaccines and a storage capacity limited to only a few cities and multiple frequencies of vaccine hesitancy. Due to these scenarios, the production of more vaccine doses and equitable distribution to the rest of the population within the Latin American region should remain a public health priority to achieve collective immunity in the shortest time possible

Authors: Side Sumiati , Putri Suriati E.
Published: August 2022

Clay is one of the essential natural minerals in human life, especially in the industrial sector, which is widely used as a raw material for ceramics fabrication, adsorbents, and photocatalysts. The characteristics of clay significantly affect the quality of the resulting material. This study will study the aspects of natural clay in Gowa Regency, South Sulawesi Province, without the leaching process and with acid leaching. Acid leaching uses 3 M HCl, previously roasted at a temperature of 600 oC. The characterization consisted of metal oxide analysis using XRF, mineral content analysis using XRD, morphological analysis, and compound content using SEM-EDX. The results showed that the primary metal oxide content in natural clay was Fe2O3, Al2O3, and SiO2, the content of Fe2O3 decreased after the raw clay was treated with acid. The main mineral content in the sample is quartz, kaolinite, and hematite. The sample's morphology looks different after being given acid treatment; the acid leaching natural clay sample shows a porous morphology, while the natural clay without acid leaching shows the morphology in the form of lumps. The EDX mapping analysis showed that the number of impurities decreased after being given acid treatment.

Authors: Li Hongyang , Guan Yuanfang
Published: August 2022

While most deep learning approaches are developed for single images, in
real world applications, images are often obtained as a series to inform
decision making. Due to hardware (memory) and software (algorithm)
limitations, few methods have been developed to integrate multiple
images so far. In this study, we present an approach that seamlessly
integrates deep learning and traditional machine learning models, to
study multiple images and score joint damages in rheumatoid arthritis.
This method allows the quantification of joining space narrowing to
approach the clinical upper limit. Beyond predictive performance, we
integrate the multilevel interconnections across joints and damage types
into the machine learning model and reveal the cross-regulation map of
joint damages in rheumatoid arthritis.

Effectiveness of post-hospital discharge pharmacist care on clinical outcomes.
Authors: Costello Jaclyn , Barras Michael , Foot Holly , Cottrell William
Published: August 2022

BACKGROUND: Clinic pharmacists have been shown to identify and resolve
medication related problems post-discharge, however, the impact on
patient clinical outcomes is unclear. AIMS: To identify hospital-based
post-discharge pharmacist clinics that provide medication review; report
the patient clinical outcomes measured; and describe the activities of
the clinical pharmacist. METHODS: Published studies evaluating a patient
clinical outcome following a post-discharge hospital clinic pharmacy
service were included. All studies needed a comparative design
(intervention vs usual care). Pubmed, Embase, CINAHL, PsycnINFO, Web of
Science, IPA and APAIS-Health databases were searched to identify
studies. The type of clinic and the clinical pharmacist activities were
linked to patient clinical outcomes. RESULTS: Fifty-seven studies were
included in the final analysis, 14 randomised controlled trials and 43
non-randomised studies. Three key clinic types were identified:
post-discharge pharmacist review alone, inpatient care plus
post-discharge review and post-discharge collaborative clinics. The
three main outcome metrics identified were hospital readmission and/or
representation, adverse drug events, and improved disease state metrics.
There was often a mix of these outcomes reported as primary and
secondary outcomes. High heterogeneity of interventions and clinical
pharmacist activities reported meant it was difficult to link clinical
pharmacist activities with the outcomes reported. CONCLUSIONS: A
post-discharge clinic pharmacist may improve patient clinical outcomes
such as hospital readmission and representation rates. Future research
needs to provide a clearer description of the clinical pharmacist
activities provided in both arms of comparative studies.
Fatty acids composition of migrated seabirds to the coastline of Pakistan as top predators to impact ecosystem variability
Authors: Akram Tahira , Sultana Razia , Munshi Alia , Rehman Haseeb-ur- , Zaidi Ayesha
Published: August 2022

Availability of fat-rich food is the critical factor for the migration
of seabirds. Predator-prey interaction shapes the food web structure and
affects environmental variability. Certain fatty acids are believed to
be the significant determining factors for environmental health and act
as energy reserves for long distant seabird migration. Three different
seabirds species investigated quantitatively for fat content and Fatty
Acid composition from Pakistani sea waters were Larus fuscus, Larus
ridibundus and Hydroprogne caspia, found significantly different for
most of the fatty acid. The average fat contents of L. fuscus, L.
ridibundus and H. caspia were 23.57±1.82%, 19.71±2.75% and
33.58±0.08% respectively. This study suggests that monounsaturated
fatty acids (MUFA) were predominantly higher than saturated (SFA) and
polyunsaturated fatty acids (PUFA) ranges from (43.49-48.07%),
(32.88-39.89%) and (14.1-16.22%) respectively.. Palmitic acid and
Stearic acid saturated and monounsaturated fatty acids constituted
>75%. The dietary fatty acid Oleic acid (C18:1n9) was most
abundant with 32-34%. The essential ꞷ-3 fatty acids were found to be
lower, whereas ꞷ-6 was found in an appreciable amount with Linoleic acid
(C18:2ώ6) as major fatty acid in L. fuscus (7.44%), H. caspia (9.81%)
and L. ridibundus (8.99%). ꞷ-3/ꞷ-6 ratio was found less than 1
indicating these seabirds as a substantial source of omega 6 fatty
acids. This study is the first report on seabirds’ diet constituents
from Pakistan to the best of our knowledge. Further experimental studies
may reveal the physiological impact of varying fatty acids from this
region.

Herein we present a case of a right ventricular (RV) thrombus in a
patient with arrhythmogenic cardiomyopathy (ACM). The 24-year old female
patient was diagnosed with ACM after echocardiography and cardiac
magnetic resonance imaging. Interestingly, at echocardiography, an
unusal thrombus formation was detected at RV lateral wall. Also, CMR
confirmed the thrombus and oral anticoagulant therapy was started. Even
in arrhythmogenic right ventricular cardiomyopathy patients thrombi are
rarely reported. However, the development of imaging techniques may
enable more frequent detection and effective treatment of thrombi in
these patients.
The effect of ‘compulsory’ indications for antibacterial prescriptions in hospital prescribing software
Authors: Pairman Lorna , Chin Paul , Gardiner Sharon , Doogue Matthew
Published: August 2022

Aim Indications for medicines are poorly recorded in prescriptions at
our hospitals. Indications are ‘optional’ on paper prescriptions but can
be mandated in electronic prescriptions. As part of an initiative to
improve indication documentation for antimicrobial medicines, a
prospective controlled study of compulsory indications for antibacterial
medicines was undertaken. Our aim was to assess the effect of making
indications compulsory in an electronic prescribing and administration
(ePA) system. Methods Compulsory indications on prescriptions were
implemented in our tertiary hospital ePA system for eight antibacterial
medicines. The proportion of ‘credible indications’ following the
intervention for these medicines was compared with 23 antibacterial
medicines with pre-existing (positive control) and 71 without (negative
control) compulsory indications. Documented indications for all
antibacterial medicines four weeks before and after implementation of
compulsory indications were extracted from the ePA system and manually
classified as ‘credible indication’, ‘other text’, ‘rubbish text’, or
‘blank’. Results The proportion of ‘credible indications’ for the
intervention group had an absolute increase of 64.8%, from 12.5%
(270/2166) to 77.3% (1684/2179). In the intervention group ‘rubbish
text’ increased by 1.3% (from 0.05% to 1.3%), ‘other text’ increased
from 5.4% to 15.3%, and ‘blank’ decreased from 82.1% to 6.1%. For
antibacterials with no compulsory indication ‘credible indications’
increased from 22.0% (793/3611) to 46.0% (1667/3621), and in those
with pre-existing compulsory indications from 80.3% (191/238) to 83.2%
(183/220). Conclusion Implementation of compulsory indications for
antibacterial medicines in the ePA system increased ‘credible
indications’ substantially with a small increase in ‘rubbish text’.

Hidden Depths: The Origins of Human Connection
Authors: Spikins Penny
Published: August 2022

In Hidden Depths, Professor Penny Spikins explores how our emotional connections have shaped human ancestry. Focusing on three key transitions in human origins, Professor Spikins explains how the emotional capacities of our early ancestors evolved in response to ecological changes, much like similar changes in other social mammals. For each transition, dedicated chapters examine evolutionary pressures, responses in changes in human emotional capacities and the archaeological evidence for human social behaviours. Starting from our earliest origins, in Part One, Professor Spikins explores how after two million years ago, movement of human ancestors into a new ecological niche drove new types of collaboration, including care for vulnerable members of the group. Emotional adaptations lead to cognitive changes, as new connections based on compassion, generosity, trust and inclusion also changed our relationship to material things. Part Two explores a later key transition in human emotional capacities occurring after 300,000 years ago. At this time changes in social tolerance allowed ancestors of our own species to further reach out beyond their local group and care about distant allies, making human communities resilient to environmental changes. An increasingly close relationship to animals, and even to cherished possessions, appeared at this time, and can be explained through new human vulnerabilities and ways of seeking comfort and belonging. Lastly, Part Three focuses on the contrasts in emotional dispositions arising between ourselves and our close cousins, the Neanderthals. Neanderthals are revealed as equally caring yet emotionally different humans, who might, if things had been different, have been in our place today. This new narrative breaks away from traditional views of human evolution as exceptional or as a linear progression towards a more perfect form. Instead, our evolutionary history is situated within similar processes occurring in other mammals, and explained as one in which emotions, rather than ‘intellect’, were key to our evolutionary journey. Moreover, changes in emotional capacities and dispositions are seen as part of differing pathways each bringing strengths, weaknesses and compromises. These hidden depths provide an explanation for many of the emotional sensitivities and vulnerabilities which continue to influence our world today.
Characterization of strongly regular integral circulant graphs by spectral approach
Authors: Basic Milan
Published: August 2022

The integral circulant graph ICGn(D) has the vertex set Zn = {0, 1, 2, . . . , n? 1} and vertices a and b are adjacent if gcd(a ? b, n) ? D, where D ? Dn, Dn = {d : d | n, 1 ? d < n}. Motivated by the incorrect proof of a previously published result, in this paper we characterize the class of integral circulant graphs that are strongly regular. More precisely, connected ICGn(D) is strongly regular if and only if n is composite and D = {d ? Dn | m ? d} for some m | n and n ? 1 ? m ? 2.

Performance of a protection system for DC grids
Authors: M.J. Pérez-Molina  , P. Eguia, D.M. Larruskain  , Aranzabal and E. Torres
Published: August 2022

The development of High Voltage Direct Current (HVDC) transmission technology is still challenging due to unresolved technical issues, mostly in terms of protecting the system. The overcurrents and voltage drop produced by fault conditions are severely dangerous to the Voltage Source Converters’ (VSC) electronic components. Hence, fast protection systems are needed. This paper proposes a full selective protection system in conjunction with hybrid HVDC circuit breakers. This protection system employs the rate-of change-of-voltage and the differential-current algorithms for primary and backup fault protections. This protection scheme is applied to a HVDC grid and an analysis of its performance is presented. This system is evaluated with several fault scenarios that include different fault characteristics. The rate-of-change-of voltage algorithm’s fast operation and the differential-current algorithm’s high selectivity are verified.

Published: August 2022

Synthesis of gold nanoparticles exhibition wide range of bioactivities and was conventionally used for the remedy of numerous disorders. Our study aims to measure the gastroprotective effect of synthesized gold nanoparticles on absolute ethanol-induced stomach ulceration in rats. The rats were noticeably administered with two doses of gold nanoparticles (175 ppm and 350 ppm) with absolute alcohol and showed a significant improvement in the adverse effect of ethanol-produced stomach damage as confirmed by decreasing ulcer index and raising % of ulcer prevention. Increased mucus pH of stomach content reduced ulcerated portion, condensed or nonappearance of edema, and white blood cells permeation subcutaneous layer. In gastric tissue homogenate, synthesized gold nanoparticles presented a substantial increase in superoxide dismutase (SOD), catalase (CAT) actions, and a substantial lessening of malondialdehyde (MDA) amount. Besides, gold nanoparticle increases the intensity of periodic acid Schiff stained (PAS) of the gastric epithelium of the stomach. Gold nanoparticles confirmed gastro-protective effects which might be qualified to its antioxidant, increase mucus secretion, increase endogenous enzymes (SOD and CAT), and reduce MDA quantity.

Authors: Gomes de Morais Artur , Da Silva Alexsandro
Published: August 2022

Neste artigo, analisa-se o que os currículos de seis diferentes países prescrevem, atualmente, sobre o ensino de leitura, compreensão e produção de textos escritos durante a etapa de educação infantil. Para tanto, realizou-se uma pesquisa documental que teve como corpus os documentos curriculares nacionais do Brasil, de Portugal, do Canadá – Quebec, da França, do México e da Espanha, os quais foram tratados por meio da análise temática categorial de conteúdo. Os resultados evidenciaram que existe, em todos os currículos examinados, um compromisso com o letramento das crianças menores de 6 anos. Sem assumir o ensino de estratégias de compreensão de leitura e de produção de textos escritos específicas, os documentos prescrevem a promoção do interesse por ler e escrever textos, as habilidades de recontar histórias e de manusear suportes de escrita. Também defendem a produção de textos coletivos, tendo o professor como escriba, além das tentativas infantis de escrita individual, mesmo que notadas com grafias ainda não convencionais.

Com base nas novas dinâmicas pedagógicas que buscam reformular as relações de ensino-aprendizagem, ainda caracterizadas pela rigidez do ensino tradicional, esta pesquisa destaca a prática pedagógica interdisciplinar, investigando a existência dela nos cursos de ensino médio integrado (EMI) do Instituto Federal do Amapá (Ifap)/Campus Macapá. A pesquisa utiliza a abordagem qualitativa, realizando a análise documental dos planos pedagógicos dos cursos e a investigação sobre a submissão de projetos de ensino com a temática interdisciplinar. Foi aplicado questionário aos docentes dos cursos de EMI para analisar a adoção de práticas pedagógicas interdisciplinares em sala de aula e verificar a opinião deles quanto às potencialidades e/ou limitações que tais práticas encontram no Campus Macapá. Os resultados constatam a existência de limitações de várias ordens (estruturais e formativas) que contribuem para que as práticas interdisciplinares ainda sejam pouco trabalhadas no EMI do Ifap/ Campus Macapá.

The paper presents the results of a model experimental study of the resource of the mating parts “piston ring - cylinder liner” of a marine diesel engine. A medium-speed trunk engine 6Ch36/45 of medium boost was chosen as a real diesel engine under study. An experimental study was carried out by using an antiwear additive containing molybdenum diselenide MoSe2 to a lubricating oil similar to that used in a circulating lubrication system. The studies are supplemented by a calculation model of the resource of the mating parts “piston ring - cylinder liner” followed by a comparison of the calculated values with the obtained experimental data. The following parameters mainly influence the resource of the selected tribological mating: the contact pressure of rubbing surfaces, the additive concentration in the oil, the shelf life of the additive before it is added to the oil without mixing it. The life tests of the parts of the “piston ring - cylinder liner” mating of a marine diesel engine made it possible to identify the effective concentration of the additive in oil by the formula Ci = 0.5÷1.0 vol. %. The resource of parts of the friction pair “piston ring - cylinder liner” increases by 1.28÷1.67 times in relation to the standard parameters of the 6Ch36/45 diesel engine. Non-compliance with the storage conditions of the additive before adding it to the oil can reduce the resource performance relative to the normative standards for of this diesel engine by 1.7÷3.45 times. It has been proved that the developed mathematical model of the service life of the parts that make up the tribological mating “piston ring - cylinder liner” has a high convergence (relative error 0.5÷5%) with the results of the experiment on the physical model of the studied friction pair “piston ring-cylinder liner”. There has been studied the influence of the volume concentration Ci of an antiwear additive on the calculated and experimental indicators of the marine diesel engine resource, the optimal value of which should not be lower than 1.0%, while the value of the contact pressure in the friction pair is up to 1.0 MPa, the time of preliminary storage of the additive is no longer than 36 hours. It has been recommended to apply the developed mathematical model to estimate the resource of the friction pair “piston ring - cylinder liner” for high- and medium-speed internal combustion engines.

Holding on the deposit of funds are their transfer in cash or non-cash in foreign, or national currency, banknote or bank currency and at the expense of the owner for compliance under certain conditions in accordance with the contract.

The agreement of the bank deposit is concluded in writing. If the bank's deposit agreement or certificates and other documents that meet the requirements of the bank's legislation, regulations or other provisions which corresponds to the written form of the bank deposit agreement (bank rules) and the customs of business.

The agreed condition that the bank has the right to change the rate of interest on the deposit in a one-way order is invalid. Interest on bank deposits is accrued from the date of receipt of the deposit by the bank and ends on the day before the depositor accepts the deposit or debiting the funds from the account of the account.

In judicial practice, there is no unanimity on the question of whether the heir has the right to receive interest on the relevant contract of the bank deposit (deposit) and the right of way of life after the death of the depositor of funds until the actual return of the deposit.

We consider it expedient to make changes to paragraph 3 of Chapter 71 of the Civil Code of Ukraine on further improvement of legislative provisions on deposit obligations, in particular by limiting and regulating the range of entities with the right to provide this type of financial services complying with their compliance with the established legislation with the requirements for professional students of this market focusing on the economic base of the main types of their activities, clarification of the legal regime of those involved in the depository fund of financial institutions and active assets defining the permissible limits between the establishment of legal succession and harmonization of approaches to the mechanism of accrual of interest in the investigated obligations

The article deals with the methodology and results of the analysis of court sentencing for crimes in the field of the use of electronic computing machines (computers), automated systems, computer networks, and telecommunication networks.

The correlation of the type and amount of punishment imposed by courts under Articles 361, 3611, 3612, 362, 363, 3631 of the Criminal Code of Ukraine is presented. The infliction of the types and amount of punishments by courts under these articles of the Criminal Code of Ukraine is analyzed, and tendencies of their imposition on the examples of concrete court sentences are distinguished. All court sentences for 2019 contained in the Unified State Register of Judgments rendered in respect of crimes under Articles 361, 3611, 3612, 362, 363, and 3631 of the Criminal Code of Ukraine are analyzed.

In addition, the authors examine the state of application of both primary and additional punishment by courts in the form of deprivation of the right to occupy certain positions or engage in certain activities and suggest ways to improve them. The authors single out the problems that arise when courts impose one or another type of primary punishment and suggest possible ways to solve them. The issue of the application of Articles 69 and 75 of the Criminal Code of Ukraine by the court in sentencing for crimes in the field of the use of electronic computing machines (computers), automated systems, computer networks, and telecommunication networks, and the expediency of exemption from serving a probation sentence or imposing more lenient punishment than provided by law, is elucidated.

Taking into account the importance of in-depth study and investigation of the problems of imposing punishment for certain criminal offenses, within the framework of this scientific work, an appropriate analysis of the state of sentencing for crimes in the field of the use of electronic computing machines (computers), automated systems, computer networks, and telecommunication networks is carried out.
Special circumstances for change or termination of housing agreement (rental)
Authors: Yavor O.
Published: August 2022

The article examines certain issues of housing law, in particular, the special grounds for changing and terminating the contract of employment (lease) of housing in today's conditions and in connection with the introduction of martial law in Ukraine. It is noted that along with the general grounds for terminating a housing (lease) contract, new special grounds for changing or terminating have appeared. In Ukraine, the legal framework for regulating housing relations is based on the following principles: freedom of contract, equality, fairness, etc. It is substantiated that the construction of housing (lease) contracts is different. Differences between contracts of hiring (lease) of housing are revealed. The features of the general grounds for terminating the contract of employment (lease) of housing have been studied. Modern judicial practice contradictoryly applies certain legislative provisions of the institution of terminating a rental agreement, which leads to the need to legislatively supplement the general grounds for terminating a housing (lease) agreement with special grounds in order to improve the quality of legal regulation of rental relations and the effectiveness of law enforcement. A necessary fact of proof is the establishment of the guilty person in creating the danger of liquidation of property.

        The recommendations on special grounds for changing and terminating the contract of hiring (renting) housing in connection with the introduction of martial law in Ukraine are analyzed. It has been established that the legislation of Ukraine provides for the right to unilaterally withdraw from the contract. At the same time, the need to provide for the following special conditions for changing or terminating the contract in the current conditions of martial law in Ukraine is substantiated: exemption from rent and/or utility bills; mutual release from the performance of obligations under the contract for the period of force majeure and force majeure, namely during the war; conclusion of additional agreements between the parties to resolve conflicts without applying to jurisdictional bodies, etc. Due to the fact that a notarial form and state registration are mandatory for contracts for real estate, and during martial law most open state registries are not available, the parties need to be more careful about agreeing on the terms of action and terminating a contract for rent (lease) of housing, remember and on the actual transfer / return of property, which must be confirmed by the act of acceptance and transfer. It is also proposed to establish legislatively that in the event of martial law in Ukraine, the legal consequence of changing the terms of the contract should be - the suspension of the fulfillment of obligations under the housing contract by mutual agreement of the parties - the landlord and the employer.
