Application of a Granular Model to Identify the Particle Size of the Granular Mixtures of Concrete Based on Dune Sands
Authors: Abdeldjalil Mhammed
Published: January 2022

The control of the determination of concrete depends on the basic properties of the desired concrete and thanks to the type of granular mixture of concrete. We arrive at the required concrete quality. And in this study, we can identify the granular distribution class of concrete using the fractal model. In particular, the granular distribution can be determined by the fractal dimension, either for each granular component separately, or for the dry granular mixture of the concrete. The fractional dimension is obtained by transforming the particle size curve to a fractal line. In this study, we used some experimental results obtained from projects already carried out in arid regions. Knowing that we have applied parameters such as granular extent and fractional dimension to the study of these existing projects, we can define a dry mix of concrete through the granular distribution. Therefore, we used the program that we proposed previously of transforming the grain size curves to a fractal line which was obtained for each grain mixture with a very acceptable correlation.

Schopenhauer und der Traum der Welt
Authors: Regehly Thomas Hermann
Published: January 2022

Träume und alles, was mit ihnen zusammenhängt, haben Schopenhauer von Jugend an immer beschäftigt. Seine “Traumdeutung” bereitete der Psychoanalyse Sigmund Freuds den Weg. Träume suspendieren die Realität der faktischen Welt, die als Welt der Vorstellung dem Satz vom Grund unterliegt. Der Begriff der Vorstellung weist in verschiedenen Aspekten eine Analogie zum Begriff der Virtualität auf, was an die Philosophie des absoluten Virtualismus des Zeitgenossen Friedrich Bouterwek erinnert. Da da die Welt als Wille und Vorstellung  ein “Erwachen” aus der Welt der Vorstellung ankündigt, führt eine Analyse am Leitfaden des Traumbegriffs auf die verschiedenen Dimensionen des Träumens selbst, deren Darstellung die Bücher 2, 3 und 4 des Hauptwerks gewidmet sind. Das bereits in der Dissertation 1813 in Aussicht gestellte Erwachen erweist sich als ein differenzierter Prozess, der auf ein anderes Verhältnis zur Welt hinausläuft, das als Erlösung oder Befreiung verstanden werden kann.

A concepção schopenhaueriana de arrependimento e angústia de consciência
Authors: Bassoli Selma Aparecida
Published: January 2022

O arrependimento [die Reue] é uma noção que surge na filosofia de Schopenhauer quando ele trata da possibilidade de um indivíduo aprimorar a manifestação do seu próprio caráter, que é aquilo que constitui o caráter adquirido. Cada um de nós possui um caráter que não pode ser mudado, mas o conhecimento sobre ele pode se aprimorar, o que permite que um indivíduo possa aperfeiçoar o conhecimento ou a consciência daquilo que ele é. Sendo o caráter a expressão daquilo que cada um quer, nós não nos arrependemos do que nós queremos, mas do que fizemos, exatamente porque consideramos que a nossa ação não foi condizente com a nossa vontade. Portanto, o arrependimento resulta do conhecimento que permite adequar o fazer ao querer. O objetivo será esclarecer a importância da primazia da vontade sobre o intelecto para a compreensão do arrependimento, assim como indicar a diferença entre o arrependimento e a angústia de consciência [die Gewissenangst].
Abstração e empatia: Schopenhauer e a fundamentação da arte abstrata
Authors: Gonçalves Rosa Gabriella Gabriella
Published: January 2022

Dentre as fundamentações que baseiam a necessidade da abstração, uma das mais interessantes provavelmente é a de Wilhelm Worringer, historiador da arte que, sendo contemporâneo das vanguardas artísticas que se iniciavam nas experimentações abstratas, tradicionalmente vinculadas a culturas primitivas, estabeleceu, em sua obra Abstração e empatia, de 1907, a contraposição entre duas abordagens artísticas: a abstração e a arte mimética, ou realista. Segundo Worringer, a arte abstrata não seria de modo algum inferior à arte figurativa, não seria o resultado de algum tipo de incapacidade de se produzir arte figurativa, e sim o produto de uma intenção inteiramente distinta, um tipo de necessidade espiritual de ordenação da realidade caótica que nos rodeia.
The benefits of cloud services usage as a contemporary approach in the wine industry
Authors: Vladisavljević Radovan , Soleša Dragan
Published: January 2022

The scope of this paper is to present the business model in the wine industry based on cloud solutions. In the modern world of business, speed and availability are crucial; unfortunately, the nature of the wine industry tends to limit the number of business participants. Managing processes in the wine industry is labor intensive so it is difficult to meet the market demand. Through the analysis of case studies and by comparison with other regions in the wine industry, we obtained enough elements for the formulation of our model. The model presented in this paper is oriented towards the domestic wine industry and is in line with current technical and technological capacities. Most of the subjects in the wine industry are located in rural areas of the Republic of Serbia, and has a relatively limited access to certain resources. There is a strong Internet infrastructure in big cities, which is unfortunately not the case with rural regions. The use of modern IT solutions is also a problematic item because participants in the wine industry, despite a solid education, have difficulty recognizing the benefits of e-commerce. With this model, the wine industry gets a tool that will make it possible to easily and economically reach customers, new ideas, knowledge and experiences.

Published: January 2022

In order for the processes of environment protection and improvement in the Republic of Serbia to be more efficient, certain financial investments are necessary. After an introductory overview, the aim of the research was presented, which is to show correlation between costs and tax revenues in the field of environmental protection. The linear regression model and Pearson's correlation coefficient were used for the analyses. The paper presents economic instruments in the field of environmental protection for the period 2009-2018. Data obtained from the National Statistical Office were used. The state of the environment, as well as the goals related to European integration with the opening of Chapter 27, show that the presented data relating to the environment in the Republic of Serbia are very worrying and represent one of the key problems for policy implementation. The obtained results showed that there is a significant degree of correlation (r = 0.887). The current situation indicates that special attention should be paid to this topic, especially in terms of finding mechanisms for providing the necessary financial funds.

Background: Collecting, monitoring, and responding to patient-generated health data (PGHD) are associated with improved quality of life and patient satisfaction, and possibly with improved patient survival in oncology. However, the current state of adoption, types of PGHD collected, and degree of integration into electronic health records (EHRs) is unknown. Methods: The NCCN EHR Oncology Advisory Group formed a Patient-Reported Outcomes (PRO) Workgroup to perform an assessment and provide recommendations for cancer centers, researchers, and EHR vendors to advance the collection and use of PGHD in oncology. The issues were evaluated via a survey of NCCN Member Institutions. Questions were designed to assess the current state of PGHD collection, including how, what, and where PGHD are collected. Additionally, detailed questions about governance and data integration into EHRs were asked. Results: Of 28 Member Institutions surveyed, 23 responded. The collection and use of PGHD is widespread among NCCN Members Institutions (96%). Most centers (90%) embed at least some PGHD into the EHR, although challenges remain, as evidenced by 88% of respondents reporting the use of instruments not integrated. Forty-seven percent of respondents are leveraging PGHD for process automation and adherence to best evidence. Content type and integration touchpoints vary among the members, as well as governance maturity. Conclusions: The reported variability regarding PGHD suggests that it may not yet have reached its full potential for oncology care delivery. As the adoption of PGHD in oncology continues to expand, opportunities exist to enhance their utility. Among the recommendations for cancer centers is establishment of a governance process that includes patients. Researchers should consider determining which PGHD instruments confer the highest value. It is recommended that EHR vendors collaborate with cancer centers to develop solutions for the collection, interpretation, visualization, and use of PGHD.

Conditions and technologies for minimization of protest activity of the Russian youth in the context of modern media discourse in digital environment
Authors: Gavrilov Sergey Dmitrievich , Pankratov Sergey Anatolevich , Azizova Diana Kachabekovna
Published: January 2022

This article is dedicated to the analysis of protest activity of the Russian youth in the context of the institutionalization of the global digital politics. The contradictions existing in the Russian political system are viewed in the form of conflict, which determines the specificity of the reproduction of protest activity of the representatives of youth cohort. The ambiguities in implementation of state policy manifest as the trigger for the formation of protest activity, including mobilization of social activity of youth in constructive / destructive behavioral practices. Research methodology is comprised of the concept of social action in interpretation of M. Weber, T. Parsons, J. Habermas, as well as the theory of social changes developed by P. Sztompka, which allows relying on the thesis of the mutual interaction of structures in relation to the actors in terms of analysis of youth protest. Interpretation is given to the results of discourse analysis of political media texts on the Internet that was conducted by the authors. The scientific novelty consists in determination of the existing expert opinions on the conditions necessary for minimizing protest activity of the youth, as well as most widespread technologies used for their implementation. Of particular importance are the results of the original empirical study that allow interpreting the two positions, which reflect the opinion within the professional environment on the role of youth in protest movement of the Russian Federation, forming the so-called “ideological foundation” for further reasoning on the state and social activity related to protesting youth.
Conflict between an individual and the state in the concept of Max Stirner
Authors: Nadtochii Igor' Olegovich , Nikishin Sergei Vyacheslavovich
Published: January 2022

The subject of this research is the views of the German classical philosopher Max Stirner on the individual, society, and the state reflected in his flagship work “The Ego and Its Own”. The object of this research is the anarchism as a unique trend in the world political and philosophical thought. On the one hand, the author emphasize the determinedness of the ideas of German philosopher by the historical atmosphere of his time, while on the other – view anarchism as the doctrine with the equally long history in the world thought and practical implementation of the anarchist concepts. The focus of M. Stirner's ideas lies in the conflict between an individual and the state. The scientific novelty of this article consists in the analysis of the essential conceptual conflict, immanent to the history of mankind, which is the foundation for M. Stirner’s original concept of the relationship between an individual, the state, and surrounding world. The trueness of being in the concept of German philosopher is determined by the embodiment of the anthropocentric, or according to M. Stirner, the “egoistic” ontological ideal. The authors' special contribution consists in the analysis of views of M. Stirner, as well as in tracing correlation between the  anarchist concepts and realization of the ideas of anarchism in one or another form. The authors show no reference to any value judgments related to this ideological phenomenon.

The problems of legal regulation of the procedure for creating testamentary trust
Authors: Litvinenko Daria Alekseevna
Published: January 2022

The institution of testamentary trust, which was Introduced as a result of the 2018 Russian inheritance law reform  and updated with the amendments to the Civil Code of the Russian Federation coming into force in March 2022, aims to ensure the efficient and lossless succession of assets by Russian citizens. The question is raised whether the current regulation of norms describing the process of incorporation meets the criteria of reasonableness and is it capable to mediate the uninterrupted transfer of the mass of succession from the control of the deceased testator to the testamentary trust. The examination of all technical legal procedures related to the emergence of a new heir allows assessing the immediacy of succession by the testamentary trust, detecting the existing flaws in legal regulation that complicate the implementation of rights and legitimate interests of the testator and beneficiaries of the testamentary trust. There are currently no scientific research dedicated to the procedure for establishing testamentary trust from the perspective of practical implementation of all stages of this process. The scientific novelty is substantiated by the absence of law enforcement practice; the testamentary trusts are not duly registered in the Russian Federation. In conclusion, the author indicates the complicated regulation of the capability of the notary to comply with the shortest terms set for the creation of testamentary trust. The author also believe that the requirement for the filing order of receiving the affidavit of heirship by the testamentary trust is unnecessary.

An interference pattern of two systems of fringes has been obtained by vising two radiations in a Hilger prism interferometer A system of white bands with equal spacing which are always parallel to the refracting, edge of the prisin is the result of the intersection of the two systems of fringes. The white bauds travel as one of the reflecting mirror in the interferometer makes a parallel displacement. Let d be the displacement of mirror when the white bauds travel one spacing, we have 1/λ2-1/λ1=1/2d. Two yellow doublets in sodium and mercury lamps were used. The values found for 1/λ2-1/λ1 were 17.22cm-1 and 63.29cm-1 respectively. A comparison of this method with the visibility corve by Michelson interfero-ineter has been discussed.

Molecular dynamics method is used to simulate the influence of the mesopore size and structure on the heat transport characteristics of the mixed nitrate. The Material Studio software is used to establish the mixed nitrate models of different scales and two structures, and the NaNO3-KNO3 models of different proportions that reach the eutectic state. By calculating the models and sorting out the calculation results, the phase transition of mixed nitrates on a nanometer scale is calculated and the micro-mechanism of heat transport characteristics is analyzed. The results show that the phase transition temperature of the solar salt first increases and then decreases with the increase of the nanopore size, and finally is consistent with the melting point on a macro scale. The proportion of cations has a great influence on the phase transition temperature of mixed nitrate, and the nanowire structures also change the phase transition temperature of nitrate. The bulk thermal expansion coefficient of nitrate decreases with the increase of mesoporous size, increases with the increase of NaNO3 content, and changes with the mesoporous structure. The enhancement of the interaction between ions will increase the thermal conductivity, but it will not have much effect on the specific heat capacity at a constant pressure.

A subwavelength electromagnetic diode scheme in a microwave waveguide system is proposed by using an asymmetric photonic crystal (PC) cavity side-coupled with electromagnetically induced transparency like (EIT-like) metamaterials. It is found that the composite PC-EIT configuration can generate tenfold Q-factor enlargement, accompanied with enhanced nonreciprocal electromagnetic localization simultaneously. Further study of the measured one-way response exhibits excellent electromagnetic diode performance including 19.7 dB transmission contrast and 7 dBm operating power at a working frequency of 1.329 GHz. We emphasize that such high-contrast transmission and low-threshold diode actions are not at costs of greatly increasing volume and drastically reducing transmission. Our findings may benefit the design of compact nonreciprocal devices in the integrated optical nanocircuits.

Relationship between Sleep Quality and Internet Addiction among First Year Medical Students in a Government Medical College in West Bengal: A Cross-sectional Study
Authors: Sengupta Debalina , Gupta Sumana , Mukherjee Suranjana Sur , Das Sulagna
Published: January 2022

Introduction: Internet overuse has emerged progressively and the pathological use of the internet- conceptualised as ‘internet addiction’– a menace which disturbs the sleep quality in a community. There is not much evidence proving the association of internet addiction and sleep disturbances and the severity of this association remains unclear. Aim: To find the association between internet addictions and sleep quality among undergraduates in a Government Medical College in West Bengal, India. Materials and Methods: This was cross-sectional observational study conducted among 211 undergraduate medical students from January 2019-March 2019 using a predesigned pretested structured selfadministered questionnaire, which consisted of information on the sociodemographic profile and lifestyle questions, Pittsburg Quality of Sleep Index (PQSI) scale and the Internet Addiction Test (IAT) scale. The participants were divided into two groups: PSQI score ≤5 (good sleep quality) and those with PSQI score >5 (poor sleep quality) and IAT scores. Statistical analysis was done using the statistical software of Statistical Package for the Social Sciences (SPSS) version 23.0. Independent sample t-test (continuous variables) and Fisher’s- exact test (categorical variables) were used to analyse the significance of difference in demographic data and IAT scores and PSQI scores between the groups. Results: Students with poor quality of sleep were having high IAT scores compared to ones with good quality of sleep and this finding was statistically significant (p-value <0.001). Among all participants 33.2% were “moderate users or possible addicts” of internet. Approximately, 49.3% of all participants had poor sleep quality and rest of them had good quality of sleep as per PSQI scale. Mean IAT score was significantly higher among participants living on campus (p=0.006) as compared to ones residing off campus. As far as sleep quality was concerned, mean PSQI scores were significantly higher among participants who were aged more than 20 years and among those who were involved in “less than three times per week physical activity” (p=0.028 and 0.004, respectively). Conclusion: Quality sleep is a key to good health and internet addiction should not hamper it. Proper counseling if needed should be done to attain it.
Reduction of Tunnelled Haemodialysis Catheters Related Infections by Intervention and Training: A 12 and 18-month Audit
Authors: Asad Riyaz Ahmed , Shrivastava Shashwat , Shrivastava Shitij
Published: January 2022

Introduction: Catheter-Related Blood Stream Infections (CRBSI) are an important complication of both non tunnelled and tunnelled haemodialysis catheters, but are often poorly reported for tunnelled haemodialysis-catheters. Aim: To assess the rate, aetiology, and outcomes of CRBSI in patients using a tunnelled catheter at 12-month and 18-month audits at the newly-opened haemodialysis unit having care bundle as a part of routine catheter care. Materials and Methods: A retrospective cross-sectional study involving two audits of CRBSI risk (12-month and 18-month audit) was conducted by the dialysis unit doctors and nursing staff at Medanta Super-Specialty Private Hospital, Indore, Madhya Pradesh, India. Centres for Disease Control (CDC) and prevention core intervention/care bundle for Blood Stream Infections (BSI) reduction were incorporated as a part of routine catheter care. The 12-month (May 2018 to April 2019) and 18-month (May 2018 to November 2019) internal clinical audit were evaluated to assess the impact of care bundle on incidence of CRBSIs. Kidney-Disease- Outcome Quality-Initiative (KDOQI)-2006-criteria was used to define CRBSI. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) version 19.0 software (IBM Corporation, New York, United States). Descriptive and dispersion statistical analysis was done for studied variables. Results: Total patients in 12-months audit with tunnelled haemodialysis catheter were 14 (7 male and 7 female) with median age 64 years and in 18-months audit patient with tunnelled haemodialysis catheter were 18 (11 male and 7 female) with median age 67.5 years. CRBSI incidence was 2.58 per 1000 catheter days at the end of 12-month, with 132 (71.25-202.25) days of median catheter use. Over the 18-month, the incidence of CRBSI dropped to 1.99 per 1000 catheter days. Median period of catheter use increased to 149.5 (83.5-294.5) days. The primary organisms isolated were predominantly gram negative bacterias. Conclusion: Tunnelled catheters may be a reasonable alternative vascular access for haemodialysis in patients with arteriovenous fistula failure as implementation and maintenance of multidisciplinary care bundle reduces CRBSI rate in such patients.
Predisposing Factors of Pseudomonas Pneumonia: A Hospital Based Cross-sectional Study
Authors: Nader Abdul Razak , Nazish Fatima , Shameem Mohammad , Bhargava Rakesh
Published: January 2022

Introduction: Pseudomonas aeruginosa (P. aeruginosa) is a usual causative organism of both hospital-acquired pneumonia and community-acquired pneumonia. Although, it is less commonly reported in otherwise healthy hosts, most patients have an identifiable risk factor for disease. These risk factors include those with structural lung abnormalities like bronchiectasis and those with a compromised immune system. With the emergence of multidrug resistant strains of P. aeruginosa, the severity of infection and mortality associated with pneumonia has increased drastically. The insight into the risk factors of Pseudomonas pneumomia helps to suspect and treat the condition at the earliest and thereby reduce the mortality as well as the duration of hospital stay. Aim: To determine various risk factors associated with P. aeruginosa pneumonia. Materials and Methods: An observational cross-sectional study was conducted from November 2018 to November 2020 at Jawaharlal Nehru Medical College, Aligarh, Uttar Pradesh, Inida, after obtaining Institutional Ethics Committee (IEC) approval. A total of 89 patients with diagnosis of Pseudomonas pneumonia, defined as the presence of signs and symptoms of pneumonia along with sputum or tracheal culture positive for P. aeruginosa were enrolled in the study. These patients were thoroughly assessed by clinical history, physical examination and relevant investigations to detect any risk factors like age, diabetes, smoking, Chronic Obstructive Pulmonary Disease (COPD), chronic steroid use and prior hospital admission. Data analysis was done using Statistical Package for Social Sciences (SPSS version 22.0). Categorical variables were compared with the Chi-square test. Results: Out of 89 patients with Pseudomonas pneumonia, 77.5% were above 40 years of age, 37.08% were smokers, 25.84% had COPD, 22.47% had bronchiectasis, 31.46% were diabetic, 15.73% were on long term steroid use and 14.61% had history of prior hospital admission. Conclusion: Age, smoking, structural lung diseases like COPD, bronchiectasis, long term steroid use and prior hospital admission are important risk factors for Pseudomonas pneumonia.

The social media concept has received much consideration from higher education since a period of ten years in India. The study was conducted for analysing the usage and effects of social media on agricultural students. The primary data was collected through questionnaire. Simple random sampling was employed, a sample of 126 students in which 100 PGDMA students from ICAR-NAARM and 26 B.Sc. Agricultural students from ANGRAU. The responses were analysed by using factor analysis and the most influenced responses were social media is a part of their everyday activity (0.88), their communication skills were improved because of social media (0.83), They felt that they were part of the social media community (0.87) and they derived satisfaction through networking and communication (0.84). These were the most affected statements from PGDMA students and B.Sc. Agricultural students. Conclusively, social media has enriched the acquaintance of individuals and build cognizance amongst students in all the aspects.

Balancing the budget is one of the most important concerns of financial policy. Improving the quality of revenue and expenditure projections has become essential for policymakers. However, The most crucial component in sustaining success in terms of revenue generation and other grounds is time. Keeping up with the speed of time is difficult. A time series model is one such method for dealing with time-based data. The time series model is an adequate model when there are serially correlated data. Autoregressive Moving Averages (ARMA) is the appropriate approach when the error(s) of the data has the same variance regardless of the value taken by the independent variable(s).  For this reason, an internally generated fund data were collected from the Twifo Hemang Lower Denkyira District assembly from 2013 to 2019 which was subjected to descriptives and time series analysis. From the time series analysis, ARMA (1, 1) was selected as the best model using the AIC value and fit the observed monthly internally generated fund pattern. The study revealed among others that January 2020 will record the highest revenue generation of 21465.96 cedis over the two years forecast followed by March 2020, 19023.17 cedis  and May 2021 of 18122.05 cedis. The study also recommended among others that the authorities of Twifo Hemang Lower Denkyira District assembly should embark on educating the citizens on the need to pay their taxes for developmental progress of their assembly.

Avocado (Persea americana Mill.) is one of the world's most important subtropical fruit crops. So far, it’s collection, systematic evaluation and utilization studies are limited and this would be perhaps the first systematic study to quantify the variability available. This investigation of genetic diversity would be a first in Tamil Nadu. Morphological diversity in qualitative and quantitative traits of avocado genotypes investigated in this study using the International Plant Genetic Resources Institute descriptors to evaluate twenty accessions. The traits evaluated were related to leaf, flowering, fruit, seed, and yield traits. The 20 genotypes were classified into ten groups using Mahalanobis statistics. PA-56 and PA-68, which differ in terms of characteristics and distance, might provide transgressive segregants upon curing to resistance desirable traits. Principal component analysis was done to assess the qualitative and quantitative characters combination. The total variability defined by the five PCs was 84.14 percent, whereas the variability of the 13 primary components was 99.99 percent. The genotypes that could be chosen based on PC values in each constituent graph that were positive and > 1.0 in each PC and a combination away that would unravel many genetic patterns.  Findings of this research will aid in germplasm management, conservation, and breeding strategies.
