DELAY IN PROCEDURES LEADING TO MISCARRIAGE OF JUSTICE
Authors: Chauhan Neeharika
Published: April 2023

Delay in judiciary is one of the few deadliest illness that a judiciary can suffer from. Even in the presence of the advanced democratic laws, a judiciary can fail in providing justice, if not given in time. Indian judiciary is already a victim to this. It lies immensely far behind the current cases and the said number is increasing day by day. Many factors exist which lead to delay in procedures. Various committees over the years have been established to deal with this problems and give solutions, like the Malimath committee, but unfortunately these steps failed. In this paper, the author has discussed these factors, categorised into procedurals and substantial factors. Procedural delays are delays which exist due to lengthy and complex procedures and procedural laws, whereas substantial factors are existing problems of infrastructure, lack of judges, etc. Further a brief comparison is made to the American judicial system, where also similar situations exist but, are less problematic than the Indian scenario. Thus, by making a comparison, we understand the certain measures which are taken up to eradicate the problem. Further, a few suggestions so as to curb this problem are also given, which have been heavily inspired from the recommendations by the Malimath committee.

TIPIFICAÇÃO DA CORRUPÇÃO PRIVADA NO CODIGO PENAL
Authors: Bonini Notari Márcio
Published: April 2023

O presente trabalho busca abordar o tema da corrupção privada à luz das normativas internacionais e suas implicações para fins de legislação brasileira. Para isso, num primeiro momento, será feita uma delimitação da corrupção privada em termos conceituais. Após, num segundo momento, será feito um exame quanto ao tratamento jurídico do crime de corrupção privada no Direito Internacional e Estrangeiro, à medida que novas abordagens vêm sendo realizadas sobre o tema da corrupção, trazendo um enfoque quanto ao setor privado. A partir desses pressupostos, busca-se traçar um panorama acerca dos instrumentos jurídicos de enfretamento a essa patologia, a qual não se encontra restringida ao exercício de uma função pública, por parte do funcionário público, nacional ou estrangeiro, mas também vem sendo operada na iniciativa privada, em que há diversas condutas praticadas por funcionários, diretores, gerentes, no âmbito das empresas e sociedades empresariais, envolvendo lucro ou favorecimentos pessoais, que demarcam a existência de uma variante de condutas ilícitas (suborno, corrupção ativa e passiva, sigilo de informações, superfaturamentos), que operam no mercado, prejudicando a livre concorrência. O Código Penal Brasileiro ainda não tipificou o crime de corrupção na iniciativa privada, estando, portanto, ausente de previsão normativa quanto sua tipicidade, requerendo a necessidade de (re) adequação, em conformidade com os tratados e convenções internacionais.

SOME ALLOCATION ISSUES OF THE PRINCIPLES OF UNCODIFIED BRANCHES OF LAW
Authors:   The Academy of the FPS of Russia, Iliukhina Vera A. ,   RANEPA
Published: April 2023

The principles of law are considered within the positivist legal understanding as the normatively fixed fundamental concept of each industry. The general legal principles enshrined in the Constitution of the Russian Federation are thought to directly apply both in codified and uncodified industries, regardless of whether they are duplicated in industry legislation or not. The article highlights a number of problems related to the allocation of the principles of uncodified branches of law. Firstly, it is rather unclear whether a particular legal entity is a specific branch of law or not. This is particularly difficult in the case of uncodified branches of law. Secondly, some of the criteria for recognising legal principles that are characteristic of codified branches of law do not work when identifying the principles of uncodified branches of law. Thirdly, sectoral principles in codified branches of law are enshrined only in the Constitution of the Russian Federation and/or sectoral codes. In uncodified branches the source of enshrining the principles of law is the Constitution of the Russian Federation and branch uncodified legislation that is a set of normative legal acts. In this situation the problem arises whether any normative legal act can enshrine the principles of the corresponding branch or only in some basic act which replaces the codified act? Finally, if the author accepts the possibility of principles of law being enshrined in different normative acts, the problem arises of the hierarchy and correlation of principles from different normative acts. The article outlines the ways to solve these challenges.
CULTURAL AND LEISURE ACTIVITIES IN THE KALININGRAD REGION IN THE SECOND HALF OF 1940s — 1980s
Authors:   Immanuel Kant Baltic Federal University, Baranova Elena V.
Published: April 2023

The article analyses cultural life and leisure activities in the Kaliningrad region during the Soviet period. The concepts of “leisure”, “free time” at different times were different in contents. On the one hand, leisure was understood as time when people recharged after hard work, and on the other hand, it meant their spiritual development. On the basis of archival and published sources, as well as interviews with immigrants, the author attempts at reconstructing the idea of leisure time activities of Kaliningrad residents on the new Soviet territory. The study also analyzed the instruments of state control which were applied to this important part of human life. In particular, the measures of the state, aimed at ensuring that the majority of free time people spent centrally, are considered. Leisure time for the Kaliningrad residents in the 1940s is considered to have been primarily a way to arrange their personal life. In the 1950s and 1960s, as the general level of well-being of the population increased, there was a demand both for the diversity of the repertoire of artistic works and for the material arrangements of leisure facilities. The 1970s—1980s were a time when leisure time was clearly influenced by foreign culture, the most active interest in which was shown by young people. Here the region was characterized by the presence of more sailors who brought home elements of this culture in the form of records, tape recorders, and other household items from their overseas voyages.

EXERGOECONOMIC ANALYSIS OF A PHOTOVOLTAIC ARRAY AFFECTED BY DYNAMIC SHADING
Authors: KESKİN Vedat
Published: April 2023

Photovoltaic (PV) panels are affected by undesirable elements that exist around them, trees, structures, clouds, etc., as well as natural dirt, and dust accumulation on the PV surfaces. Unfortunately, partial shading falling on top of the PV panels may affect badly the output of photovoltaic arrays. In this study, an exergoeconomic analysis has been performed on the impact of dynamic partial shading created by a mislocated building on a photovoltaic array. Both experimental and theoretical results of this study have been compared on ambient temperature, solar radiation intensity, and shading ratio. The observations have been carried out on clear days starting in June 2018 to Mai 2019. According to the results, the shaded PV exergy efficiency (6.87%) and exergoeconomic parameter (Rex= 0.18508 W/$) are maxima in June and minimum in February (Ex =4.76%, Rex= 0.12228 W/$). As a result of this study, it can be said that the PV array exposed to long-term shading will seriously affect the service life of the PV array.

This system has two control angles horizontally and vertically. In this study, the yaw and pitch angle control parameters of the TRMS system were found using both traditional and butterfly-based particle swarm optimization (BFPSO) method. In experimental studies, reference values of main propeller and tail propeller angles were tried to be reached in TRMS with fractional order proportional-integral-derivative (FOPID), proportional-integral-derivative (PID) and tilt-integral-derivative (TID) controllers.
AN EFFICIENT CALIBRATION PROCESS FOR THE PREDICTION OF ROCK STRENGTH THROUGH MACHINE LEARNING ALGORITHMS
Authors: DİNÇ GÖĞÜŞ Şaziye Özge
Published: April 2023

Numerical models based on the discrete element method (DEM) have been widely used to predict the mechanical behaviors of rocks in rock engineering applications. Nevertheless, calibration of the model parameters is done by running numerous simulations and this time-consuming simulation process precludes the numerical platforms to be used as a practical tool in such applications. This study aims to accelerate the calibration process of the micro-parameters of three-dimensional (3D) numerical models built based on DEM and facilitate the generation of an efficient database by using machine learning algorithms in the prediction of rock strength. Namely, these algorithms are linear regression (LR), decision tree (DT) regression, and random forest (RF) regression. The appropriate methodology for predicting the uniaxial compressive strengths (UCS) of certain rock types was investigated using a dataset consisting of micro-parameters of 87 DEM-based rock models, generated through an open-source code, Yade. The performance of such methods was evaluated by using metrics including R-squared score (R2), mean squared error (MSE), root mean squared error (RMSE), and mean absolute error (MAE), and then their statistical discrepancies were analyzed. The most accurate prediction of UCS was obtained in the LR method and the lowest percentage of performance was derived from the RF algorithms. LR method provides the results efficiently during calibration of the micro-parameters of a DEM-based rock model.

Albert Camus’ eksistentsialismi jooni Priit Pärna filmides
Authors: Nurk Paul Kaspar
Published: April 2023

Comparison of two works benefits the understanding of both of them. The comparison finds the overlap between the works along with the standpoints that distinguish them. The interpretation of these works is broadened and also more distinctly delimited. The article examines the films of Estonia’s most accomplished animation director Priit Pärn for signs of existentialist thought, based on Albert Camus’s The Myth of Sisyphus. Close textual analysis was used to answer the research question: which existentialist traits appear in Priit Pärn’s films, and how they resemble and differ from Albert Camus’s view of existentialism. The research found numerous parallels between Priit Pärn’s filmography and Camus’s existentialist thought. One of the leitmotifs of Pärn’s films is the prevalence of preposterous totalitarian systems, where the prevailing situation is nearly identical to one in which the absurd man would discover the absurd. Various characters from these worlds have lost their human shape in a way that causes discomforting alienation in the viewer, which is one of the absurd discoveries mentioned by Camus. Though many of Pärn’s characters are similar to the absurd man, only in one of the films are they able to free themselves from the rigid routine conclusively. However, none of the characters recognize the absurdity of the system around them: they either live under its hardship or those who free themselves resemble the absurd man only in their actions, not in their mentality, because they do not act upon a logical discussion. Distinctive to Pärn’s style, the unrestricted approach to reality aligns with Camus’s reluctance about the mindset that treats humans and everything else as if they had a definite place and purpose in the world. Priit Pärn’s films have many similarities with Albert Camus’ existentialism. Although juxtaposing them reveals that while Camus concentrates on a mentality on how to interpret and embrace the absurd, Pärn’s films focus on the absurd and the absurd systems themselves, along with describing the burdens they bring about.

The use of environmental DNA (eDNA) to assess aquatic biodiversity is a growing field with great potential for monitoring and managing threatened species, like freshwater mussel (Unionidae) populations. Freshwater mussels are globally imperiled and serve essential roles in aquatic systems as a food source and as a natural water filter making their management essential for ecosystem health. Unfortunately, mussel populations are often understudied, and challenges exist to accurately and efficiently describe the full suite of species present. Multispecies eDNA approaches may also be more challenging where freshwater mussel populations are most diverse due to ongoing and significant taxonomic restructuring that has been further complicated by molecular phylogenies using mitochondrial genes. For this study, we developed a microfluidic metabarcoding array that targets a wide range of species, from invertebrates to fishes, with an emphasis on detecting unionid mussels known to be present in the Sipsey River, Alabama. We compared mussel species diversity across six sites with well-studied mussel assemblages using eDNA surveys and traditional quadrat surveys in 2016. We examined how factors such as mussel population density, biomass and location in the river substrate impacted our ability to detect certain species; and investigated unexpected eDNA detections through phylogenetic analysis. Our eDNA results for fish and mussel species were broadly consistent with the data from traditional electrofishing and quadrat-based field surveys, although both community eDNA and conventional sampling detected species unique to that method. Our phylogenetic analysis agreed with other studies that treat Pleurobema decisum and P. chattanoogaense as synonymous species; however, they are still listed as unique species in molecular databases which complicates their identity in a metabarcoding assay. We also found that Fusconaia flava and F. cerina are indistinguishable from one another using a portion of the NADH dehydrogenase Subunit 1 (ND1) marker, which may warrant further investigation into whether or not they are synonymous. Our results show that many factors impacted our ability to detect and correctly identify Unionidae mussel species. Here we describe the obstacles we faced, including the murky phylogeny of Unionidae mussels and turbid river conditions, and our development of a potentially impactful freshwater mussel monitoring eDNA assay.

Published: April 2023

Background

The effects of hypoxia inducible factor-2α (HIF-2α) deficiency on liver fibrosis have not been demonstrated in a fibrosis model induced by carbon tetrachloride (CCl4). We aimed to examine whether hepatocyte-specific HIF-2α deletion could ameliorate CCl4-induced liver fibrosis in mice.

Methods

Hepatocyte-specific HIF-2α knockout mice were created using an albumin promoter-driven Cre recombinase. HIF-2α knockout (KO) mice and floxed control wild-type (WT) mice were fed a normal diet (ND) and received either twice weekly intraperitoneal injections of CCl4 solution (CCl4 dissolved in olive oil) or the corresponding amount of olive oil for 8 weeks. The indicators of liver function, glucose and lipid metabolism, and liver histology were compared among the different groups.

Results

Hepatocyte-specific HIF-2α knockout had no effect on the growth, liver function, glucose or lipid metabolism in mice. CCl4-treated KO and WT mice had a similar pattern of injury and inflammatory cell infiltration in the liver. Quantification of Masson staining, α-smooth muscle actin (α-SMA) immunohistochemistry, and the hydroxyproline (HYP) content revealed similar liver fibrosis levels between KO and WT mice injected intraperitoneally with CCl4. Immunohistochemistry analysis suggested that HIF-2α was mainly expressed in the portal area and hepatic sinusoids but not in hepatocytes. Bioinformatics analyses further indicated that HIF-2α expression was neither liver specific nor hepatocyte specific, and the effect of HIF-2α in hepatocytes on liver fibrosis may not be as important as that in liver sinuses.

Conclusions

Hepatocyte HIF-2α expression may not be a key factor in the initiation of liver fibrogenesis, and hepatocyte-specific deletion of HIF-2α may not be the ideal therapeutic strategy for liver fibrosis.

Introduction: Health-Related Quality of Life (HRQoL) aims to measure a person’s views on the impact of their disease. Children suffering from thalassaemia require frequent blood transfusions throughout their lives because of impaired Haemoglobin (Hb). This may necessitate them to stay in the hospital for a longer transfusion day. School, physical activities, competencies, and family stability are all compromised in some way. Assessing HRQoL in individuals with thalassaemia and identifying variables that contribute to low quality of life is crucial. Aim: To correlate HRQoL and factors affecting among different age groups in transfusion-dependent thalassaemia patients. Materials and Methods: A cross-sectional study was conducted at MGM College and Hospital, Navi Mumbai from October 2020 to August 2021, 70 thalassaemia patients aged 8-25 years registered for regular blood transfusions were included in the study and divided into three age groups: Group-I (8-12 years) n=25, II (13-17 years) n=24, and III (18-25 years) n=21. The study was approved by Institutional Ethics Committee. Paediatric Quality of Life (PedsQLTM) 4.0 generic core scale questionnaire was used to assess patients’ HRQoL. This questionnaire has 2 parallel reports: child self-reports and parent proxy reports and assess HRQoL across four dimensions: physical, emotional, school, and social functioning. Anthropometric and demographic parameters considered are height, weight and age. Pretransfusion Hb and ferritin levels, Cardiac iron overload, age of first transfusion, frequency of transfusion, annual blood requirement were collected and correlated with HRQoL scores. One-way ANOVA, unpaired student’s t-test and Pearson’s correlation were applied for statistical analysis and p-value less than 0.05 was considered significant. Results: Comparison of total mean score of child’s self-report between three age groups showed significant difference (p=0.001). In Group-I, the lowest score was for physical functioning (41.9±18) and significantly correlated with pretransfusion Hb, annual blood requirement, and age of first transfusion. In GroupII, the lowest score was for school functioning (54±18) and significantly correlated with pretransfusion Hb, annual blood requirement, cardiac iron loading, and Age of first transfusion. In Group-III, the lowest score was for school functioning (50.9±12) and significantly correlated with pretransfusion Hb, ferritin level, age of first transfusion, annual blood requirement, and frequency of transfusion. Conclusion: The HRQoL scores of thalassaemia patients was low in parent’s report as compared to children’s report in all four dimensions in all three groups. The predominant factors affecting are pretransfusion Hb level, Annual blood requirement, and age of the first transfusion.

Introduction: In developing countries, cervical cancer is the leading cause of death amongst women. Since women spend one third of their lives in the postmenopausal period, which is most neglected phase, needs a technically simple, non invasive and, cost-effective screening tool for cervical cancer detection and the exact answer is the Pap smear screening test. This simple screening test when performed at regular intervals in post menopausal population, can detect precursor lesions there by reducing cervical cancer morbidity and mortality. Aim: This study was undertaken to evaluate the cytomorphological variations in Pap smears amongst postmenopausal women. Materials and Methods: In this prospective study, a total of 138 satisfactory smears were considered for study amongst 146 postmenopausal women from August 2020 to July 2022 at Bhaarath Medical College and Hospital and then evaluated and categorised based on Bethesda system for reporting cervical cytology 2014. {Reporting elements include specimen type, specimen adequacy, general categorisation, interpretation/result includes general categories of negative for Intraepithelial Lesion or Malignancy (NILM), epithelial cell abnormalities and other malignancies. Results: Out of 138 satisfactory cases, 78.26% (108 cases) 14.5% (20 cases) and 7.24% (10 cases) were diagnosed as of inflammatory/benign conditions, epithelial abnormalities and normal cytology respectively. The mean age for inflammatory/ benign lesions was 57.5 years and majority presenting with postmenopausal bleeding and white discharge. Amongst epithelial abnormalities Atypical Squamous Cells of Undetermined Significance (ASCUS) and Low-grade Squamous Intraepithelial Lesions (LSIL) were commonest. The incidence of ASCUS 7.27% (10 cases), and incidence of LSIL 2.89% (4 cases). The mean age was 57.5 years and majority of patients presented with postmenopausal bleeding and mass per vaginum. Incidence of High grade Squamous Intraepithelial Lesion (HSIL) was 2.17% (3cases), the mean age was 65.5 years and presented with white discharge and postmenopausal bleeding. Incidence of SCC was 2.17% (3 cases) and the mean age was 70.5 years, presented with, postmenopausal bleeding and white discharge. Conclusion: Pap smear is a simple, cheap, safe and gold standard diagnostic tool for screening postmenopausal women for all cervical abnormalities in particular pre-invasive and invasive lesions.
