Objective: To compare the frequency of SARS- CoV-2 infection between Sero-positive and Sero-negative healthcare workersafter 6 months in a tertiary care hospital.
Study Design: Prospective Cohort study.
Place and Duration of Study: Combined Military Hospital, Kohat Pakistan, from Aug 2020 to Jan 2021.
Methodology: Two Hundred and eighty-eight healthcare workers were included by non-probability consecutive sampling. They were divided into two groups according to SARS-CoV-2 IgG-Ab status at baseline as sero-positive and sero-negative. They were followed for six months period and symptomatic healthcare workers were tested for SARS- CoV-2 infection by RT PCR. Individuals from all departments were included and used standard personal protective equipment.
Results: Out of 288 Healthcare workers 240(83.33%) were male and 48(16.67%) were female. At baseline, 42(14.58%) individuals were sero-positive and 246(85.42%) were sero-negative for SARS-CoV-2 Ab. During 6 months of follow up 28(11.38%) symptomatic sero-negative Health Care Workers were tested positive for COVID-19 infection by RT PCR. None of the sero-positive Health Care Workers was tested positive for SARS-CoV-2 infection. Risk of infection was higher in sero-negative group (Odds ratio 1.19 with 95% CI; 1.13- 1.26).
Conclusion: SARS-CoV-2Ab may offer immunity againstCOVID-19 infection as no infection was observed in sero-positive individuals as compared to 11.2% in sero-negative individuals.

Objective: To compare the frequency of anastomotic leakage in interrupted versus continuous, single layer extramucosal anastomotic techniques in jejunum.
Study Design: Quasi-experimental study.
Place and Duration of Study: Combined Military Hospital, Multan Pakistan, from Feb 2020 to Feb 2021.
Methodology: Patients aged 15-60 years, from the indoor surgical department of the hospital who required jejunal anastomosis were selected. Patients were categorized as Group-A (interrupted single layer extra mucosal anastomosis) or Group-B (continuous single layer extra mucosal anastomosis).
Results: The mean age was 43±9.5 years in Group-A and 41.6±10.1 years in Group-B. Eighteen patients (56.3%) in Group-A and 21(65.6%) in Group-B were male while 14 patients (43.67%) in Group-A and 11(34.4%) in Group-B were females. Frequency of anastomotic leakage was recorded as one patient (3.13%) in Group-A and 3(9.38%) in Group-B while rest of the patients in both groups had no anastomotic leakage (p=0.302). Chi square test was applied, which showed statistically insignificant difference between the two groups (p=0.32)
Conclusion: Comparatively higher frequency of anastomotic leakage was recorded in patients treated with continuous as compared to interrupted suturing but the results were statistically insignificant.

В статье рассмотрены факторы, влияющие на качество чугуна при серийном производстве отливок с использованием новых модификаторов. Представлены результаты исследования механических свойств, микроструктуры и термического анализа. Механические испытания проводились на образцах, вырезанных из ступенчатой отливки, а микроструктурные исследования – с помощью светового микроскопа и сканирующего электронного микроскопа. Результаты термического анализа показывают, что введение модификаторов увеличивает минимальную температуру затвердевания эвтектики и, таким образом, повышает вероятность зарождения вермикулярной формы графита в чугуне. Увеличение потенциала образования зародышей графита может быть достигнуто путем добавления модификаторов, полученных из отходов кремниевого производства. Модификаторы, полученные из отходов кремниевого производства, содержащие диоксид кремния и углеродные наночастицы, оказались наиболее выгодными модификаторами с точки зрения получения наилучших параметров микроструктуры и пластических свойств серого чугуна.
The purpose of the study was to determine the factors affecting the metallurgical quality of cast iron in the mass production of castings using new modifiers. The results of the study of mechanical properties, microstructure and thermal analysis are presented. Mechanical tests were carried out on samples cut from step casting, and microstructural studies were carried out using a light microscope and a scanning electron microscope. The results of thermal analyses show that the introduction of modifiers increases the minimum solidification temperature of the eutectic and, thus, increases the likelihood of the formation of the vermicular form of graphite in cast iron. An increase in the nucleation potential can be achieved by adding modifiers obtained from silicon production waste. Modifiers obtained from silicon production waste containing silicon dioxide and carbon nanoparticles turned out to be the most advantageous final modifiers in terms of obtaining the best microstructure parameters and plastic properties of gray cast iron.
The cult of the written constitution and the dilemmas of constitutional changes: scientific approaches and practice of deliberative constitutionalism
Authors: Kravets I. A. 
Published: June 2024

The subject. The article discusses the scientific foundations of the cult of a written constitution, the relationship between the principles of the supremacy of the constitution and fidelity to the constitution, on the one hand, and the forms and methods of constitutional changes in modern democratic states, on the other hand.The aim of the article is to reveal the dilemmas of legal constitutionalism in the context of the formation of doctrinal foundations and the practice of applying deliberative and dialogical constitutionalism in modern jurisprudence and the practice of constitutional development.Methodology. The author uses deliberative and epistemological approaches, methods of formal-legal, concrete-historical, comparative constitutional-legal and complex analysis. Main results, scope of application. A special field of knowledge is being formed, which is called “comparative constitutional changes”. The scientific school of constitutionalism proposes to see the purpose of this field of knowledge in the development and improvement of forms and methods of participation of the people, citizens, civil society, professional and expert opinion in constitutional changes. The study provides a critical constitutional analysis of the peculiarities of the nature of all-Russian voting and the legal positions of the body of constitutional justice in Russia on the issue of all-Russian voting, prospects for improving the principle of popular sovereignty and the institutions of citizen’s participation, civil society, professional and expert opinion in the Russian constitutional doctrine and in legislation.Conclusions. The cult of a written constitution dominates in the contemporary world of democratic constitutional states that differ in socio-economic and political-legal indicators of their development on the geopolitical and legal map of the planet. In the practice of contemporary states, except for the adoption of a draft new constitution, the most common practice is to express individual preferences (“for” or “against”) citizens regarding the content of each amendment or several interrelated amendments. The theory of deliberative constitutionalism is multifaceted and is intended to scientifically substantiate the prospect of expanding the constitutional basis for democratic decision-making and creating a democratic basis for constitutional change. Deliberative constitutionalism, as a theory of engagement in constitutional communication, serves the purpose of seeking collective wisdom in matters of constitutional design and constitutional change. The cult of a written constitution is combined with an inclusive constitutional paradigm for the development of democratic states, which involves the development of deliberative and imperative forms of citizen’s participation. Russian constitutionalism needs to further expand popular participation in the development and discussion of decisions of a constitutional nature.
In the field of gravity: the structure and elements of public power
Authors: Larichev A. A. , Kozhevnikov О. A. 
Published: June 2024

The subject of this study includes the approaches to the definition of the category of public power, as well as variants of its structure and elements.The goal of the article is to compare the experience of various jurisdictions, including Russia, in the construction of public power, and to establish contemporary determinants of its structure and consequences of its expansion. Comparative and formal legal methods are mainly used to produce the results of the research.Main results. The authors notice, that in most jurisdictions legislative attempts to give a definition of the structure of public power and to indicate the circle of its subjects entail indeterminacy and the inevitable expansion of the corresponding subject composition. That, apparently, is caused by the dynamics of the functions of public power, which determines the institutional evolution. It is not a secret that since the beginning of the 20th century the volume of functions entrusted to the state, and accordingly, to its bodies of power and management, has grown significantly. Since there are plenty of tasks and functions that correspond to the public interest, the state involves in the process not only its structural units the bodies of state power, but also private subjects. Private entities, mobile and adapted to competition and social-economic changes, are capable of more effective implementation of tasks, performance of functions and provision of services that can be administratively outsourced. In the USA, for example, this phenomenon becomes so large-scale that it sometimes referred to as "mixed administration" in academic literature. In Russia, the possible forms and limits of the involvement of private subjects in the implementation of public tasks continue to remain under question, both from a theoretical and a practical point of view.Conclusions. Formation of the structure of public power is influenced by historical, sociocultural, and legal features of the development of states. In most jurisdictions the basis ("locus of gravity") of public power is comprised of the authorities (both of state and municipal level), in the orbit of which, depending on the need for the implementation of public functions, other subjects of law – public and private companies and even NGO’s – are included. Therefore, functional unity is the main determinant of the structure of public power mechanism.
Global legal anomie in the international legal system: general theoretical aspect
Authors: Malko A. V. , Lipinsky D. A. , Markunin R. S. , Ivanov A. A. 
Published: June 2024

The subject of the study is international legal norms and global processes associated with their non-compliance and the substitution of rules for norms. The article analyzes current problems of global legal anomie, characteristic of the modern international legal system and international life. Consistent and systemic measures are proposed to prevent and counter this type of legal anomie. In this regard, possible directions for the development of the domestic legal system are determined.The purpose of the study is to determine the characteristic features of global legal anomie and outline ways out of it.Methodology. The dialectical method of cognition, philosophical laws of unity and struggle of opposites, the transition of quantitative changes into qualitative ones, as well as comparative legal and formal legal methods are defined as the methodological basis of the study.The main results. In the process of research, the authors prove that the legal system, which is in a state of legal anomie, is becoming increasingly unsystematic, fragmented and segmented in nature, within which internal connections and interactions are minimized, and its organizing role is inevitably reduced. The article argues that the process of global legal anomie is associated with the complete or partial absence of the necessary (new) legal norms that ensure the formation of multipolarity, and with the imposition of new rules by several states, which to a greater extent form the excessive regulation of international legal relations. The authors explain the concept and characteristics of legal anomie in the international legal system. There is a need to establish mechanisms in the domestic legal system that prevent the entry of international law norms or the manifestation of other components of the international legal system that contradict the Constitution of the Russian Federation and cause legal anomie.Conclusions. It is necessary to find a balance between different national legal systems, which would allow them to mutually enrich themselves with the achievements of their social and legal life. The authors propose the following definition of global legal anomie. It is a type of social anomie occurring in the international legal sphere as a result of a loss of trust in international institutions and rapid changes during a crisis (transition) period, representing a negative (destabilizing) component of international life and characterized by dysfunctionality and inconsistency of the components of the international legal system. Global legal anomie is most clearly expressed: firstly, in the complete or partial absence of the necessary (conditionally new) norms of international law, secondly, in neglect of existing norms, and also, thirdly, in the massively deviating legal implementation activities of subjects of the world communities.

Redesign and heterogeneous computing
Authors: Edgeley James , Sanderson Allen , Xing Jacques 
Published: June 2024

This session focuses on the redesign of Nektar++ operators to enable the heterogeneous (CPU/GPU) computing and its comprises the following talks
1. Multi-level pipelining for improved GPU performance
2. Redesigning the Nektar++ Operators for CPU/GPU Execution, a WIP
3. Performance TimingMulti-level pipelining for improved GPU performanceOptimising performance on GPUs requires careful shepherding of data through the different levels of memory to their arithmetic operations and then back through memory. By overlapping data transfers and calculation in a pipeline it is possible to minimise bottlenecking and obtain the best performance from the device. This general approach can be employed at all levels of the GPU memory model. Two examples are discussed: a pipelined kernel for local operators and a graph-based execution model.
The pipelined kernel has been implemented in CUDA and applied to some of the redesigned Nektar++ operators. Using double buffering and tuning the work-per-thread to hide latency it is possible to achieve significant speedups over existing latency-bound methods.
As well as optimisations to the kernels themselves, further improvements can be achieved by reordering and overlapping the kernels with data movement. A directed acyclic graph model with support for several backends has been implemented. Expensive memory copies and kernel launch overheads are avoided. Encapsulating operations on blocks of data as nodes in this graph allows for greater parallelisation and scalability.
Redesigning the Nektar++ Operators for CPU/GPU Execution, a WIPAs part of the Nektar++ redesign efforts the operators have been brought under one roof so to easily allow for different implementations to be developed, maintained, and deployed. Two keys parts of the development and maintenance allow code that is common across the implementations to be utilized. The remaining differences typically amount to a few kernels. In some cases, no differences remains thus allowing for a “universal” implementation. The second key part was the introduction of the execution and memory space paradigm. This paradigm was key to being able to deploy the operators across the CPUs and GPUs without any need for “device” specific implementations. This talk will be a bit of “deep dive” as many of the paradigms introduced will be used throughout the redesign progresses.GPU Performance Benchmarking for the Nektar++ RedesignNektar++ is being redesigned as a collection of operators to allow different implementations targeting various hardware architectures. As high-performance computing (HPC) clusters are moving more and more toward heterogeneous architectures, parts of the Nektar++ redesign efforts involve the offloading of operators workload to GPUs. However, efficient use of GPUs notably requires proper memory access and high occupancy rate. In this respect, this work present preliminary performance benchmarking results for the 2D and 3D BwdTrans operators using CUDA and Kokkos implementations exploiting both single-level and hierarchical parallelisms.
