Authors: Qasir Abbas  , Latif Iqra , Muneer Mehwish , Khan Muhammad Umar , Baig Khawer Bilal
Published: April 2023

This study explores the relationship between distress tolerance and depression with mediating role of anxiety-related symptoms and stress among dropout and non-dropout university students. This cross-sectional study was conducted from October 2019 to December 2020. Participants' age ranged between 20-40 years. Data was collected using the Distress Tolerance Scale and Depression Anxiety and Stress Scale. Descriptive, t-test, and mediation analyses were performed to calculate the results. A sample of 500 respondents was recruited. A significant difference was noted between dropout and non-dropout students on CGPA (p<.001), depression (p<.001), anxiety (p<.001), stress (p<.001), tolerance (p<.001), absorption (p<.001), appraisal (p<.001), and distress tolerance (p<.001). Mediation analysis reveals that stress and anxiety significantly mediates between distress tolerance and depressive symptoms (i.e., F (498) = 31.14, p< .001; F (498) =34.14, p< .001; F (496) = 161.21, p< .001). It is concluded that low distress tolerance increases stress and anxiety, triggering depressive symptoms.

Published: April 2023

Superior mesenteric artery (SMA) aneurysm is a rare disease, especially if it is mycotic (infective) in origin. It is difficult to detect the problem during its initial natural course and usually presents in late phase due to its complications such as rupture, dissection, haemorrhage, and mesenteric ischaemia. Initially, the patient present with non-specific symptoms like vague colicky abdominal pain, nausea, vomiting, discomfort, malaise, and low-grade fever but prompt workup and intervention can lead to definitive diagnosis and uneventful outcome. This report describes the case of a 60-year-old male patient who presented with non-specific abdominal symptoms and, on workup, was diagnosed with superior mesenteric artery mycotic aneurysm. It was successfully treated surgically by resection of aneurysm and reconstruction of superior mesenteric artery by inter-positional Polytetrafluoroethylene (PTFE) synthetic vascular graft.

Serum Magnesium plays a significant role in different diabetic complications. This comparative cross sectional study was conducted to evaluate serum magnesium levels in patients with Type 2 Diabetes Mellitus (T2DM) with and without nephropathy. A total of 182 diabetic patients (91 with nephropathy and 91 without nephropathy) were included. Odds ratio were calculated and Mann Whitney U test was used to compare quantitative variables; p<0.05 was considered significant. The results showed that 64/91 (70.3%) patients with nephropathy had hypomagnesaemia as compared to 21/91 (23.07%) patients without nephropathy. The risk of hypomagnesaemia was higher in patients with nephropathy than without nephropathy (Odds ratio 2.7 vs 0.34). Median magnesium levels (1.73 mg/dl) were lower in patients with nephropathy as compared to patients without nephropathy (2.09 mg/dl), p <0.01. It is concluded that magnesium levels were significantly lower in patients with diabetic nephropathy as compared to without nephropathy.

Synthesis and characterization of bentonite based zinc complexes
Authors: ANAVATAN Gülsüm Ece , ANT BURSALI Elif , YURDAKOÇ Mürüvvet
Published: April 2023

In chemical reactions, the use of environmentally friendly catalysts obtained by transporting transition metals on solid or polymer carrier materials has become quite common recently. Studies in which zinc complexes are used as homogeneous and heterogeneous catalysts are frequently encountered in the literature. In addition to many advantages of homogeneous catalysts, disadvantages include difficulty separating from the reaction medium, recycling, and limited chemical-thermal stability. Solving problems can be solved by using solid catalyst sup-port materials and transferring the active ingredients to these materials. Therefore, catalysts prepared by transporting transition metal complexes onto solid supports have become interesting for researchers. Natural or processed clays can be used as catalysts or catalyst carriers and have many uses due to their cheapness and abundance. In this study, natural Enez/Edirne bentonite was acid-activated (HB) and converted to organo-clay (HB/CTAB) with hexadecyl-trimethylammonium bromide (CTAB). Then, heterogeneous catalysts were prepared by direct transport of the synthesized [Zn(acac)2H2O] or [Zn(p-H2NC6H4COO)2]1.5H2O complexes onto modified clays separately. The catalysts have been characterized by X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis, surface scanning electron microscope, and Brunauer-Emmett-Teller specific surface analysis methods.

Published: April 2023

Consumer purchasing in Zimbabwe has always been dominated by Bricks and Mortar shops with few online stores. When COVID 19 set in the paths of consumers in March 2020with restrictions on movement but with needs and wants to be met, many firms were forced to re think their marketing strategies which saw a rise in digital marketing in Zimbabwe. Consumers are always seen as savvy animals with ever changing needs and wants, all to be met by the firms through the supply of goods and services. Therise in consumer needs, competition and declining income levels during and after COVID 19 made firms to blend their marketing strategies and encompass the recent digital marketing strategies. This was the optional marketing strategy firms were left toembrace as Zimbabwehas a 90% mobile phone ownership per household (Maphosa, 2021). The study was informed by Theory of planned behaviour. The target population for the study was low to medium income segment of the market mainly comprising of university students. Conveniencesampling technique was used and the interviewer used respondents that were easy to reach and the planned number of interviews was 25, however 18 interviews were conducted, data saturation (Kumar, 2011) was reached and no further data was gathered. The study results showed differed perceptions from consumers based on their technological knowledge towards ICT but mainly many consumers showed willingness to embrace digital purchasing in the 21Stcentury although many challenges included fear of cyber crimes, poor network, cost of data, age of the consumer and social networks influence. The results from the study will help many organisations in drafting their digital marketing strategies using consumer based perceptions
Development and Study of aNew KeynesianSmall Open EconomyModel for Policy Analysis in Sudan, Evidence from DSGE Model
Authors: Arabi Naeem Mahmoud Hamid , Mohamed Arabi Prof. Khalafalla Ahmed , El-Maeia DR. Howida Adam
Published: April 2023

The purpose of this paper is to create a small open economymodel for monetarypolicy discussion and analysis. Anew Keynesian model for the Sudanese economy is developed using the DSGE technique. The paper made use of annual data from the period (1998 -2021). The paper demonstrates that, in the case of a fully-fledged Islamic monetary system, the exchange rate canbe used as a proxy for the policy rate and yield results that are consistent with what was expected. The main findings are that when monetary policy shocks occur, an increase in the exchange rate directly leads to a contraction in aggregate demand, thefluctuations in output in the short run are primarily driven by output, inflation, and exchange rate shocks, that the response of the variables to policy shocks is consistent with economic theory and what is expected from the variables, and that the empirical findings of the model demonstrate how models can help in policydiscussion and analysis. The policy implications were that Sudanese authorities can use the exchange rate to track the dynamics in monetary policy DSGE models that can be used for discussion and policy analysis, and Sudanese monetary authorities must pay close attention to output fluctuations based on variance decomposition analysis.

Published: April 2023

This article presents experimental evidence and a description of the scientific discovery «The phenomenon of electric current excitation in a conductor moving in an electrostatic field». The first class of effects I will show you are those caused by the electrostatic force. It is the force that controls the movement of atoms, collides, and generates heat and light energy. This force also causes atoms to combine in an infinite number of ways according to nature's fantastic designs, and to form all the amazing structures we see around us. According to Maxwell's theory, an eddy magnetic field should always appear when the electric field changes. In our work, we will study relatively low-frequency changes in the magnetic field, which are negligible compared to its theoretical calculation. In addition, there is every reason to believe that in practice no magnetic field occurs inside the capacitor. The conclusions of these works can be confirmed by the operation of the Tesla transformer, whose high-voltage end is connected to a single capacitor, which in turn forms a capacitor with the surface of the Earth. Due to the quarter-wave distribution, we can only observe the electric field around this capacitor, and the magnetic field appears in the current (ground) part of this transformer.

Nonlinear oscillations of a rod with residual stress in the presence of contact dry friction
Authors:   Astana IT University, Sergaziyev M.
Published: April 2023

Wave processes are studied in an elastic rod interacting with its environment according to the law of dry friction. Oscillations of the system at residual stresses are emerged under the influence of instantaneous unloading. Analytical solution of the partial differential equation of hyperbolic type with a nonlinear mechanism of energy dissipation is obtained. Thus, it makes it possible to describe the oscillatory process at various loading parameters of the system for an arbitrary section of the rod. The property, that for the class of problems under consideration dry friction does not change the natural frequency of the system, is shown additionally. The problem can be considered as a model for describing dynamic processes in rocks under the effect of internal stresses. Results of the modeling problem allow us to conclude: if we consider that rocks resist differently to tension and compression, such as resistance to tension is less than compression’ resistance, it is obvious that in the case of relatively rapid unloading of the system, the residual compressions will create stresses that correspond to the first maximal displacements of the end section, and that exceed the limit of tensile strength as well. In this case, the edge sections undergo the brittle fracture that can be sustained by the tensile stresses of the subsequent maximum displacements.

Parents’ Reasons for Sending Children to Pre-primary Schools: A Case of Kaskazini ‘A’ District Zanzibar
Authors: Muhammed Shehe , Mligo Ignasia , Seni Abdalla
Published: April 2023

Purpose: This study explored parents' reasons for sending their children to pre-primary education in Zanzibar. The reasons are discussed with respect to their understanding of pre-primary education as a basic education in Zanzibar.

Methodology: A qualitative approach with a case study design was used; data were collected using face-to-face interviews from 36 parents, 14 males and 22 females who had children in pre-primary schools. The study was done in the light of the Expectancy Value Theory (EVT) that relates the expectations and values a person has over something, and proposes that achievement behaviour is primarily influenced by expectancies of success and subjective task values.

Findings: The results showed that most parents understood that early childhood education was a basic education in Zanzibar due to the fact that it is a starting point for children to learn basic life skills and literacy skills. Therefore, it was revealed that parents were sending their children to pre-primary schools because they wanted their children to be literates, prepared for primary education and learn socialization. It was revealed that early childhood education teaches children different skills like reading, writing, counting and socialization skills, and so changes a child from having a home-mind to school-mind. 

Unique Contribution to Theory, Practice and Policy: The study recommends to the curriculum developers to plan and design early childhood education programmes to achieve the targets of the parents so as to encourage them in sending their children to pre-primary education as well as increase their involvement in their children’s education.
Russia Amidst the War: Implications for Human Rights and Political Freedoms
Authors: Terzyan Aram
Published: April 2023

This paper explores the state of human rights and political freedoms in Russia amid the Russian invasion of Ukraine. The ongoing Russian-Ukrainian war has devastatingly affected the state of human rights and political freedoms across Russia. The vague and ill-defined laws introduced in Russia amid the war severely restrict the citizens’ fundamental rights and freedoms, leading to a massive crackdown on government critics. This has significantly undermined Russia’s international standing, while leading to the Kremlin’s further rejection of democratic norms. More worryingly, Russia’s restrictive policy has been further combined with its decision to withdraw from the Council of Europe which raises a series unanswered question regarding the future of its human rights commitments. This paper concludes that Russia is isolating itself from the greater international community and resembling a North Korean-style form a tyranny.
Civil Liberties and COVID-19 in Uzbekistan and Kyrgyzstan: Rising Authoritarianism?
Authors: Terzyan Aram
Published: April 2023

This paper explores Uzbekistan’s and Kyrgyzstan’s responses to COVID-19, with a focus on its implications for political freedoms and human rights across the two Central Asian countries. Along with devastating public health systems, and causing lockdowns of nations, COIVD-19 pandemic has posed formidable challenges to human rights worldwide. A well- informed observer notes that with a gratuitous toll being inflicted on democracy, civil liberties, fundamental freedoms, healthcare ethics, and human dignity, this has the potential to unleash humanitarian crises no less devastating than COVID-19 in the long run (Thompson and Eric 2020). Thus, one of the biggest questions regarding the political implications of the pandemic involves explaining the extent to which governments have violated democratic standards in their response to COVID-19.

Published: April 2023

Level of profit generated from adoption of paddy innovations can influence famers’ decision to adopt such innovations; however it is imperative to know whether there are profit differences between adopters and non-adopters of innovations. This study was conducted in Mvomero District, Tanzania. The main objective is to compare profitability among adopters and non-adopters of selected innovations. Cross-sectional research design is employed and simple random sampling technique is employed to select 299. The interview uses a semi-structured questionnaire. Net farm income (NFI) and Return on investment (ROI) are used to analyze the profitability for selected innovations. Content analysis is used to analyze qualitative information. The study reveals that adoption of SRI, PTs and WTs is more profitable compared to non-adoption of the same innovations (p < 0.01). Adoption of SRI, PTs and WTs to farmers in the study area is a profitable venture (p < 0.01) and serves as a stimulus for other farmers to apply the innovations in paddy production. Extension officers and rural development agents should educate farmers especially those who do not adopt innovations on the advantages of adoption of paddy innovations so as to improve their wellbeing.

Fast Simulation of Urban Waterlogging Based on Multi-Objective Machine Learning Model
Authors: LAI Chengguang , LIAO Yaoxing , WANG Zhaol , CHEN Xiaohong
Published: April 2023

The frequent occurrence of urban waterlogging disasters induced by rainstorm has recently caused serious economic losses and casualties in China. Numerical simulation of waterlogging is an important tool for disaster prewarning and forecasting as well as disaster prevention and control; however, the traditional numerical physical models have the disadvantage of low computational efficiency, which makes it difficult to meet the demand for real-time simulation and real-time early warning and forecast. To this end, this study combines the respective advantages of coupled rainstorm-flood models with physical mechanisms and machine learning algorithms, and proposes a rapid prediction and simulation method for inundated depth of urban waterlogging based on multi-objective machine learning algorithms. The forecasting performances of K-Nearest Neighbors(KNN), Multi-Objective Random Forest(MORF), Extreme Gradient Boosting(XGBoost) and their integrated models are discussed, respectively. The results show that: (1)The coupled rainstorm- flood model based on SWMM and LISFLOOD-FP has good applicability in the simulation of urban waterlogging induced by rainstorm in the study area. On this basis, the database with a total of 70 scenarios of rainstorm-inundation with different characteristics were generated. (2)The KNN, MORF, XGBoost and their integrated models all have good results in predicting water depth, with Pearson correlation coefficient (PCC)values all above 0. 812, mean absolute error(MAE)below 6. 9 cm, and root-mean-square error (RMSE)less than 0. 116. The KNN-MORF-XGBoost integrated model has the best overall results, with the average values of MAE, PCC and RMSE reaching 2. 4cm, 0. 965 and 0. 043, respectively. (3)In addition to the high prediction accuracy, the prediction speed of the constructed multi-objective machine learning prediction model is extremely fast, and the water depth simulation efficiency is more than 20 times higher than that of the coupled rainstorm-flood model. This study can provide a reference for the application of machine learning in the rapid simulation of urban waterlogging induced by rainstorm, which is of great value for the early warning and forecast of urban waterlogging disaster.
Research on the Synergistic Development Measurement of Construction Land Scale and Population Scale in Urban Areas of Counties in China
Authors: ZHANG Xueru , LIU Zewei
Published: April 2023

In order to quantitatively portray the degree of synergistic development of construction land scale and population scale in county urban areas in China, this paper uses elasticity coefficient model and deviation coefficient model to measure the sequential change characteristics, spatial divergence differences and the degree of synergistic development of population scale and construction land scale of county units in each province in China based on the data of China Urban and Rural Construction Statistical Yearbook from 2006 to 2016. The results of the study show that: ①Both the number of population and the area of land for construction in counties in China show a trend of first increasing and then slightly decreasing, reaching a peak in 2014 and then slowly decreasing; ②In the process of rapid urbanization, the urbanization rate of county units in China is much smaller than the national average urbanization rate, and the urbanization level of counties is less than half of the national urbanization level. Therefore, the main force driving China’s urbanization process comes from the development of large and medium-sized cities, rather than county units. Besides, population transfer is more inclined to large and medium-sized cities than to county cities; ③ Based on the elasticity coefficient model, it is concluded that except Henan, Shanxi and Qinghai provinces, the other provinces in China are in a situation where the scale of construction land in county urban areas is not coordinated with the scale of population, and the type of incoordination is of the type of A disproportionate growth of people and land (the growth rate of the scale of construction land area and the scale of population are both positive and the growth rate of the former is greater than that of the latter); ④According to the deviation coefficient model, it is concluded that the scale of construction land scale and population growth in county units in China are not coordinated. Eighteen provinces in China are in a state of high dissonance, accounting for 64. 29% of the total. The average deviation coefficient for their degree of coordination is 2. 32, much higher than the average coefficient of deviation of 1. 5 in China. The relevant research results can provide theoretical reference for realizing the sustainable and healthy development of county cities, optimizing the structure of county units and improving utilization efficiency of county unit resources.

Conflitos entre migrantes e locais
Authors: Bach Luccas César
Published: April 2023

O presente estudo tem por objetivo tecer uma análise da construção das identidades regionais dos protagonistas dos romances A bagaceira (1928), de José Américo de Almeida, e The grapes of wrath (1939), de John Steinbeck. Ambos os romances propostos têm como cenário a migração em massa em períodos de crise social ou econômica e, em decorrência desses acontecimentos notoriamente históricos, famílias foram deslocadas de suas comunidades. Essa migração é o que trataremos como um movimento de desenraizamento. Entende-se “desenraizamento” como a retirada do indivíduo de seu espaço no mundo – seja essa “retirada” voluntária, forçada, ou mesmo sazonal –, levando-o à condição de estrangeiro em um novo espaço em que as memórias e a sociedade não lhe são familiares, então necessitando reconstruir sua percepção de comunidade e identidade. O indivíduo deslocado à posição de migrante é posto em posição fragilizada contra o integrante da comunidade local por seu isolamento social. Os pré-conceitos regionais são em grande parte responsáveis pela desconfiança generalizada entre esses grupos, causando um embate entre pessoas que ocupam posições de classe semelhantes, e encerrando um ciclo de violências contra as personagens desenraizadas. Assim, faz-se necessário trabalhar com obras que dialoguem com a posição do imigrante, como Said (2003) e Sayad (1998), entre outros.
“O homem da areia” de E.T.A. Hoffmann
Authors: Muñoz Mauricio Mancilla
Published: April 2023

O artigo tem como objetivo reconhecer o motivo do inquietante como uma categoria estética fundamental no universo romântico, especialmente na obra “O homem da areia” de E.T.A. Hoffmann. A hipótese central deste trabalho é que o fenômeno do inquietante, no que diz respeito à leitura do texto de Hoffmann, tem sido interpretado de forma restrita pela tradição psicanalítica. Para alcançar esse objetivo, em primeiro lugar será proposto uma caracterização provisória do inquietante como categoria estética; em seguida será apresentado uma visão geral sobre o assunto baseado no conto “O homem da areia”; na terceira parte será exposto a interpretação psicanalítica do inquietante de Sigmund Freud em contraste com a proposta de Ernst Jentsch; e por último, será abordada a tarefa de uma poética do inquietante. O universo poético dos românticos alemães é caracterizado por tornar evidente um mundo interior marcado com matizes claro-escuro, onde a obra literária tenta mostrar o que nem sempre é visível.

The capability to successfully monitor online tests has become important for the evolution for the next stage of education. At present, manual proctoring has become the most frequently used form of evaluation, where the student/test-taker is required to go to a specific examination centre, or by proctoring tests using a webcam. Though, such techniques are not cost effective and difficult. In this project, we aim to develop a system that accomplishes the goal of automated online proctoring. The proposed system hardware comprises of a single webcam, and a mic., with the goal of tracking the audio and visual surroundings of the location of test. The model comprises of six components that always measure the behaviour of the user : user authentication, text detection, audio detection, and tab switching detection. By combining the continuous estimation components, and using a temporal sliding window, we design higher-level features to determine whether the test taker is cheating at any time during the test. To test our proposed system, we collect multimedia data (audio and visual) from the test taker performing various types of cheating while taking online tests. Extensive experimental results demonstrate the accuracy, robustness, and efficiency of our online proctoring system.

Android platform due to open source characteristic and Google backing has the largest global market share. Being the world's most popular operating system, it has drawn the attention of cyber criminals operating particularly through wide distribution of malicious applications. This paper proposes an effectual machine-learning based approach for Android Malware Detection making use of evolutionary Genetic algorithm for discriminatory feature selection. Selected features from Genetic algorithm are used to train machine learning classifiers and their capability in identification of Malware before and after feature selection is compared. The experimentation results validate that Genetic algorithm gives most optimized feature subset helping in reduction of feature dimension to less than half of the original feature-set. For machine learning classifiers, a classification accuracy of over 94% can be maintained with a large feature reduction, thereby improving classification accuracy computational complexity of learning classifiers.

Cardiovascular diseases are one of the most fatal health conditions worldwide, posing a significant burden on national healthcare systems. Several risk factors, including high blood pressure, family history, stress, age, gender, cholesterol, BMI, and an unhealthy lifestyle, have been identified for these diseases. Early diagnosis is crucial for effective treatment, but the accuracy of existing approaches needs improvement due to the life-threatening nature of cardiovascular disorders. This study proposes a MaLCaDD framework for precise prediction of cardiovascular diseases. The methodology addresses missing data and imbalances, using Feature Importance to select relevant features, and an ensemble of Logistic Regression, SVM, Random Forest, Decision Tree, and KNN classifiers for accurate prediction. The study shows that MaLCaDD outperforms current state-of-the-art techniques, making it a trustworthy tool for early detection of cardiovascular diseases. The developed framework will be thoroughly tested and validated using different evaluation metrics, including sensitivity, specificity, and area under the curve, to ensure its accuracy and reliability. The ultimate goal of this project is to provide healthcare practitioners and policymakers with a reliable tool for predicting an individual's cardiovascular disease risk, which can help in early intervention and management, and ultimately reduce the burden of cardiovascular disease on society.

For the local treatment of a number of bowel disorders such as ulcerative colitis, Crohn's disease, amoebiasis and sand, colonic cancer, the local treatment of colonic pathologies, and the systemic distribution of protein and peptide medicines, targeted drug delivery into the colon is extremely desirable. A medication must be properly formulated for colon-focused drug delivery. To ensure sudden or controlled release in the proximal colon, the substance must first be shielded from degradation, release, and absorption in the upper GI tract. The advantages and disadvantages, cutting-edge methods for colon-targeted drug delivery, clinical evaluation methods, and some details about commercial dosage forms are the main topics of this paper

Eliminating resource waste is a key objective in the modern world. To do this, local communities can reuse resources like food that may be close to expiring in restaurants, stores, and food distribution facilities as well as any perishables that aren't consumed entirely within their intended shelf life. This is very important, especially in times of crisis like the COVID-19 pandemic. This study focuses on developing a fascinating initial webapp called CHERISH that offers a universal platform where users may visualise available resource resources in their neighbourhood and afterwards acquire access to resources, so addressing two key challenges, namely hunger and resource waste. This platform meets the broad category of AI for and is relevant to the UN SDGs (United Nations Sustainable Development Goals).

Non-governmental organizations or NGOs, are primarily nonprofit groups, and a large portion of them are supported by members of NGO and public donations. The credibility of an NGO is substantially enhanced and donor confidence is greatly increased by maintaining transparency regarding how donations are used. Donor organizations provide funding to non-governmental organizations(NGOs) in developing various initiatives such as economic development, women’s empowerment, promoting education, responding to calamities and natural disasters. Due to some NGOs’ involvement in the misuse of funds, some donor agencies cease to have faith in NGOs method of operation. This system is decentralized, not owned or operated by a single person or organization but rather shared among users. We have developed a blockchain-based Donation System capable of decentralizing the resources used by a given organization. The user may create any new organization and others will be allowed to donate money in the organization. As a result, the public become the true owners of the resources, and the charity fund system as a whole becomes more transparent. Blockchain technology and distributed ledgers can reduce operational costs and bring us closer to real-time transactions between financial institutions. System uses cross chain protocol for reliably exchanging information without third party in a multiple Blockchain system

In today’s world, when information safety is essential, blockchain is supreme for distributing that information because it gives instantly, provides, and completely unambiguous information stored on an immutable (unchangeable) ledger that can be accessed only by authorized network members. Blockchain increases trust, safety, clarity (Transparency), and the traceability of information transferred across a network. Today voting systems tolerate different safety threats and similarly distributed denial of service attacks (DDoS). Polling booth capturing, vote modification, and unfairly, gaining unlawful(unofficial) access to a computer system. The main objective of a similar fashion would be to deliver a decentralized(single organization cannot handle it) design to run and boost a voting system that is openly and separately(Independently) confirmable. The benefit that we get using of E-voting scheme would be to lessen election expenditures involving material, employee salary, and logistics records. If a voter is not physically present(out of the station) then he can vote remotely. That is it enhances a great degree of attendance. E-voting can be beneficial because anybody can effortlessly access the election. The security of E-voting in terms of verification(Authentication), clone(duplicate) votes, and non-repudiation of votes, is very less. E-voting is being studied hugely, and most of the execution is verified and even used for a while. That’s why very few executions (Implementation) are reliable sufficiently and are still in use
