FORENSIC AND BEHAVIOR ANALYSIS OF FREE ANDROID VPNS
Authors: Wangchuk Tashi , Rathod Digvijaysingh
Published: October 2021

Millions of users worldwide use VPN clients to either circumvent censorship or to access geo-blocked content, and specifically for privacy and security purposes. In the pretext of secured communication and privacy, numerous free android-based VPNs are being pushed up in the Google Play store. However, the users aren’t sure or aware of whether the VPN is truly secure or just leaking their data. So, the forensic and behavior analysis of selected free android VPNs was carried out to study the usability of free android-based VPNs in terms of providing security and privacy; specifically, the presence of dangerous permissions, malware presence, traffic encryption, the DNS leaks, and the possibility of leaving forensic artifacts on the device after the VPN use. The study revealed considerable portion of the sample free VPNs were flagged malicious and had dangerous levels of permissions in use. While some failed the DNS leak test and some VPNs even did not encrypt the traffic. Given the availability of a huge number of Free VPNs in the Google Play store, it was found important that the users must be aware of the inherent risks put by the use of these Free VPNs.

Three Cases of Gradual Degradation Mode Analysis of Semiconductor Laser Diodes
Authors: Huang Jack Jia-Sheng , Wang C. K. , Jan Yu-Heng
Published: October 2021

Semiconductor laser diodes are important components for various applications such as 5G wireless, datacenter, passive optical network, and aerospace applications. High reliability has emerged to be the universal requirement for all optical applications. To achieve high reliability, fundamental understanding of the laser degradation behavior is crucial. In this paper, we study three cases of gradual degradataion modes of laser diodes including (1) Pattern-A that is associated with threshold current change only, (2) Pattern-B that involve both threshold current and power changes, and (3) Pattern-C that is associated with merely power change. We have instituted reliability equations for the degradation processes. The new reliability models could provide estimation on the laser end-of-life based on the degradation rate and device performance specification.

The volume consists of two parts, one of which comprises analyses of filmic transmediations of Shakespeare’s sonnets (The Sonnetproject, New York Shakespeare Exchange 2013), the other analyses of literary ekphrases (by W. Szymborska, U. Fanthorpe, J. Stone etc.). It results from an Intermedial studies seminar held in 2021 within the program Literature and Intercultural Communication at Masaryk University, Brno. The contributions display various approaches that fall under two main intermedial methods, literature-centered (introduced by Werner Wolf), which focuses primarily on a semantic analysis of the original text, and literature-oriented (as suggested by Irina Rajewsky), which respects the transmediation as an autonomous representation and observes its relations to the pretext mainly retrospectively; and even a comparative one, which involves a translinguistic analysis of translations as intercultural and historical transfers.
Whatever Happened to Voltaire?
Authors: Noyer G. K. ,   Philosophy Documentation Center
Published: October 2021

The eighteenth century French Enlightenment writers—Voltaire and Montesquieu especially—were cited in American textbooks as the thinkers who most influenced the founding generation of America until at least the 1970s. They still are, throughout much of the world. And rightly so, as studies of colonial periodicals and pamphlets have largely shown. When and why did they disappear from our high school textbooks? When Voltaire is mentioned at all, it is only as the author of Candide. This essay focuses on Voltaire as a sort of “missing link” in our understanding of American history and government. It includes discussions of his other works, considered far more consequential in his own day, and of his ubiquitous use of critical thinking. The case of Voltaire closely parallels the more recent efforts to erase Thomas Jefferson from U.S. schoolbooks: the author of the first bill for religious freedom and its leading champion in America.
Dramas of Dušan Kovačević in course of Serbian language and literature
Authors: Ćupić Zorana
Published: October 2021

In the paper, we will deal with literary knowledge and reading competencies of a student which are necessary for a coherent literary and methodically based interpretation and evaluation of the genre in contemporary literature teaching on the example of three dramas by Dušan Kovačević: Claustrophobic Comedy, Professional and Hilarious Tragedy. The purpose of the paper is to show how complex and significant the reading of a dramatic text can be, and perhaps unfairly neglected in teaching practice, given how important it is to research and define the literary knowledge and competencies that are necessary for the student to acquire by reading and studying the genre and reach the level of creative reaction to it. The purpose of the paper is to point out the linguistic and stylistic characteristics and theoretical basis of the drama from the corpus of research, which would methodically justified give the possibility of their incorporation into the high school curriculum.
Banovic Strahinja between the song and film
Authors: Ralović Ivana
Published: October 2021

This paper brings insight into the content and analysis of the screenplay "Soko" (The Hawk) (1977) which Saša Petrović (1929-1994) created according to the epic folk song "Banović Strahinja". Critical approaches to adaptations are numerous and varied, and in this paper we rely on newer theories (Robert Stam, Linda Hutcheon, Dudley Andrew, David Krantz, Thomas Leitch, Sarah Cardwell...) which perceive the adaptation for other media as an autonomous work of equal status as the original work and which reject fidelity to the original as the criteria for appraisal of adaptations. The comparative approach in this paper was used to see the way in which the narrative, thematic and aesthetic elements were created for the needs of the new media. In addition to the analysis of literary segments, we have included the analysis of film, intertextual and contextual elements, which we considered relevant for the interpretation and assessment of the adaptation. Petrović is a director who, although he made famous his country's cinematography in the world, did not receive the opportunity to record this film. Special attention in this paper is dedicated to the scene within the tent of the Vlah Alija and the scene with the wolves, and both of them conform to the Genet's notion of paraleptic continuation, which illustrate Petrović's creative manner in the process of adaptation of the literary work.
Relationship of serum adiponectin and resistin levels with the severity of liver fibrosis in patients with chronic hepatitis B
Authors: Čustović Nerma , Rašić Senija
Published: October 2021

Background: Recent research has closely linked adipocytokines to liver inflammation and fibrosis progression in patients with non-alcoholic liver disease. This study aimed to determine the relationship of serum adiponectin and resistin levels with the severity of liver fibrosis in patients with chronic hepatitis B (CHB), depending on the duration of antiviral therapy. Methods: The cross-sectional study included 75 patients with CHB divided into two groups: the T1 group (undergoing antiviral therapy for up to 2 years) and the T2 group (undergoing antiviral therapy over 2 years). The control group consisted of 40 healthy people. Serum concentrations of adiponectin and resistin were estimated with the ELISA method, while the degree of liver fibrosis was determined using FIB-4 and APRI score. Results: There were no statistically significant differences in the mean serum adiponectin levels in relation to the duration of antiviral therapy. Higher values of serum resistin concentration were confirmed in patients of the T1 group compared to healthy controls (p=0.001) and to the T2 group (p=0.031). The mean level of serum resistin concentration was significantly higher in the group of patients with a higher FIB-4 score (9.12±3.39 vs 5.58±3.36 ng/mL, p=0.001) and higher APRI score (17.45±3.96 ng/mL vs 4.82±1.11 ng/mL, p=0.001). A positive correlation was found between serum resistin levels and the degree of liver fibrosis (p<0.001). There was no significant difference between mean serum adiponectin levels according to the values of FIB-4 and APRI scores. Conclusions: Progression of liver fibrosis estimated by FIB4 and APRI scores as well as the length of antiviral treatment had a significant effect on serum resistin values in CHB patients on antiviral therapy.

Authors: Lipovka Aleksei Yur'evich , Fedchenko Irina Gennad'evna
Published: October 2021

This article is dedicated to examination and testing of the modern methods of morphological analysis of the territories of large-scale residential development. The urban planning theory marks the emergence of works on the study of morphotypification of residential construction of different periods. A number of recent publications provide the analysis of the morphotypes of urban environment using GIS technologies to determine such parameters as the density of urban fabric, porosity and ratio of open and closed spaces, number of storeys in a building; nature of the relative positions of buildings in a residential group, neighborhood unit, etc. The author outlines the new vectors in studying construction patterns and evolution of topography of large-scale residential development plan. The goal of this research lies in determination of the morphological periods of large-scale residential development in Krasnoyarsk based on the analysis of topology, study of the structure of the plan based on geoinformation data analysis. The article aims to determine the construction periods of large-scale residential development through the use of mathematical analysis; analyze the topology of the plan of living quarters of various construction periods; establish the morphotypes of residential planning units that are characteristic to the periods of large-scale residential construction; substantiate the morphological periods of neighborhood units of large-scale residential development. The author describes the typical morphotopes of residential development of the city based on determination of the preferred geometry and number of storeys in a building: “ribbon”, “dot”, “spline”, “L-shaped”, “U-shaped”, “circuit”. The article conducts a comprehensive calculation of morphotopes based on the key indicators, and reveals the morphotypes characteristic to different periods of large-scale residential construction: 1st period (1960–1975) – “ribbon development”; 2nd period (1975–1990) – “sporadic building” due to varying geometry of the building plan; 3rd  period (1990–2010) – “mixed housing” due to coexistence of different types of buildings; 4th period (2010–2020) – “homogeneous development” due to the presence of typical, recurring morphotope. Substantiation is given to morphological periods of residential construction.

adaptación de los medios públicos al mercado digital: el caso de la televisión valenciana À Punt
Authors: González Saavedra Carlos
Published: October 2021

Objetivo: Analizar cómo se adapta À Punt, la cadena de televisión pública de la Comunidad Valenciana, al cambiante escenario digital actual, marcado por la expansión de las plataformas digitales y las nuevas pautas de consumo; y establecer qué estrategias son las más adecuadas para asegurar la vitalidad y la relevancia de un servicio público de televisión territorial.Diseño/metodología/enfoque: A partir del enfoque teórico de Philip Napoli, que tipifica las respuestas organizativas recurrentes de los medios a las amenazas competitivas de las nuevas tecnologías, el estudio considera tres grupos de acciones estratégicas de À Punt: diversificación, mimetismo y diferenciación. Se aplica una metodología mixta basada en el estudio de documentos cualitativos de la propia corporación, en datos empíricos sobre redes sociales, aplicaciones móviles y audiencias digitales, y en entrevistas a responsables de la corporación.Resultados: Aunque À Punt dispone de ingresos bajos con relación a la renta autonómica y a la población, una plantilla corta y escasos índices de audiencia, al ser una cadena nativa digital (comenzó sus emisiones regulares en junio de 2018), ha implantado un modelo multiplataforma (TDT, web, aplicaciones, HbbTV) y está ubicuamente presente en las redes sociales. No obstante, aún es incipiente el desarrollo de una estrategia que aporte coherencia a estos esfuerzos y permita crear y distribuir contenidos digitales con base en los valores diferenciales de un servicio público de ámbito territorial.Limitaciones e implicaciones: Las limitaciones de las metodologías actuales para la medición de audiencias digitales, no permite disponer de unas métricas más fiables para el análisis. Además, al tratarse de un medio de comunicación muy joven, todavía no dispone de un plan estratégico e indicadores de calidad asociados al proceso de digitalización.Originalidad/contribución: Abordar las estrategias de las corporaciones públicas para adaptarse al mercado digital desde la perspectiva de una televisión territorial.
Comunicación y populismo 2.0 en la nueva política española:
Authors: González Castro Jacob
Published: October 2021

Objetivo: El objetivo principal de esta investigación consiste en analizar, desde el punto de vista de la Comunicación, el acercamiento que dos partidos de reciente creación en España, Unidas Podemos y Vox, ejercen hacia una corriente en auge en toda Europa: el populismo. Se pretende así detectar posibles semejanzas y diferencias en las que hayan podido incurrir ambas formaciones a este respecto.

Diseño/metodología/enfoque: Esta investigación analiza, mediante la técnica del análisis de contenido, las publicaciones que los dos partidos han realizado por medio de sus cuentas de Facebook y Twitter, acotando estas al período correspondiente a la campaña electoral que concluyó con la celebración de la primera de las dos elecciones generales que tuvieron lugar en España durante el año 2019, concretamente el 28 de abril.

Resultados: Los resultados confirman que, tanto Unidas Podemos como Vox, actúan como partidos que abrazan una nueva modalidad de populismo para llegar al mayor número de votantes posible. Adoptan, por tanto, una estrategia semejante, a pesar de sus diferencias ideológicas, cuyo antagonismo queda patente en la adaptación que cada uno de ellos hace de este pensamiento político.

Limitaciones/implicaciones: Las principales limitaciones de esta investigación se hallan en el número de partidos analizados, en las plataformas de comunicación estudiadas, así como en el período electoral. La ampliación de estas variables ofrecería, a su vez, un incremento de los resultados.

Originalidad/contribución: La aceptación que la sociedad española ha demostrado del populismo no conllevaba hasta ahora, y a diferencia de como ocurría en la mayor parte de los países de Europa, la entrada en el Congreso de un partido de ideología de extrema derecha. Un nuevo actor que llega, con una gran acogida por parte de la ciudadanía, para disputar un espacio al resto de formaciones, siguiendo la misma estrategia comunicativa que su mayor opositor.

Dilution refrigerator and its heat transfer problems
Authors: Fu Bai-Shan , Liao Yi  , Zhou Jun ,   Institute for Quantum Science and Engineering, Southern University of Science and Technology, Shenzhen 518055, China,   Center for Quantum Transport and Thermal Energy Science, School of Physics and Technology, Nanjing Normal University, Nanjing 210023, China
Published: October 2021

In the research of cryogenic physics and quantum information science, it is essential to maintain a steady low temperature of millikelvin regime continuously. Dilution refrigerator is a widely used refrigeration device to achieve extremely low temperature. It utilizes the phase separation effect of superfluid 4He and its isotope 3He mixed solution at ultra-low temperatures. The performance of heat exchanger is the key factor to determine the performance of continuous cycle refrigerating machine. At extremely low temperatures, there appears a huge interfacial thermal resistance between helium and metal (Kapitza resistance), and the problem of heat exchange can be effectively solved by using the porous sintered metal particles to increase the contact area. Therefore, it is of significance to study the heat exchange between metal particles and liquid helium at extremely low temperature and to develop the relevant high-performance sintered Ag powder heat exchanger.
Evaluation of Usability of the Tiger Full Foot 3D Scanner for the Measurements of Basic Foot Dimensions in Clinical Practice
Authors: Laštovička Ondřej , Cuberek Roman , Janura Miroslav , Klein Tomáš
Published: October 2021

Background: Foot dimension information is important both for footwear design and clinical applications. In recent years, non-contact three-dimensional foot digitizers/scanners became popular as they are non-invasive and are both valid and reliable for the most of measures. Some of them also offer automated calculations of basic foot dimensions. The study aimed to determine test-retest reliability, objectivity, and concurrent validity of the Tiger full foot 3D scanner as well as the relationship between the manual measures of the medial longitudinal arch of the foot and its alternative parameters obtained automatically by the scanner. Methods: Intraclass correlation coefficients and the values of minimal detectable change were used to assess the reliability and objectivity of the scanner. Concurrent validity and the relationship between the arch height measures were determined by the Pearson's correlation coefficient and the limits of agreement between the scanner and the calliper method. Results: Both the relative and absolute agreement between the repeated measurements obtained by the scanner show excellent reliability and objectivity of linear measures and only good to nearly good test-retest reliability and objectivity of the arch height. Correlations between the values obtained by the scanner and the calliper were generally higher in linear measures (rp{greater than or equal to}0.929). The representativeness of state of bony architecture by the soft tissue margin of the medial foot arch demonstrate the lowest correlations among the all measurements (rp{less than or equal to}0.526). Conclusions: The Tiger full foot 3D scanner offers both excellent reliability and objectivity in linear measures, which correspond to those obtained by the calliper method. However, values obtained by the both methods shouldn't be used interchangeably. The arch height measure is less accurate, which could limit its use in some clinical applications. Orthotists and related professions probably appreciate scanner more than other specialists.
Total Dystrophic Onychomycosis Successfully Treated with Efinaconazole Topical Solution in Times of COVID: A Case Study
Authors: Garoufalis Matthew G
Published: October 2021

Toenail onychomycosis is a common condition that is equally challenging for podiatrists and patients. This case study documents a 26-year-old woman with bilateral total dystrophic onychomycosis of at least 5 years' duration. She had previously failed to respond to treatment with ciclopirox nail lacquer 8% and despite hiding her condition with nail polish, was suffering from embarrassment, distress and low self-esteem. At initial consult, one hundred percent of both great toenails were affected. After discussion of all treatment options, the patient opted for topical efinaconazole 10% solution, once daily for 48 weeks. Significant improvement was noted at the first (4 week) assessment period. This improvement was maintained through each subsequent virtual consult and complete cure was seen at a 30-week follow-up visit. To the author's knowledge this is the first published report on the use of efinaconazole in total dystrophic onychomycosis. It suggests that the product may be effective in patients with even the most severe and treatment recalcitrant disease, who are unwilling or unable to tolerate systemic antifungal therapy.
Problematizing Scientization in International Organizations
Authors: Bekele Teklu Abate
Published: October 2021

Comparative education studies examined the roles multilateral organizations and non-governmental organizations play in global governance and international development. Emphasis has been given to their engagements both at policy and practice levels as well as their impacts. Generally, the mechanisms international organizations use to govern education and development seem qualitatively to change over time. The most recent emerging research trajectory explains how international organizations primarily use the power of scientific knowledge for organizational legitimacy, credibility, and impact. This is referred to in the literature as soft governance, epistemic governance, scientization, or scientific multilateralism, as it significantly relies on the authority of scientific knowledge as opposed to hard, financial preconditions, for global governance and development. Our understanding of scientization is still in its ‘infancy’, partly due to its relatively recent emergence and partly due to the use of varied indicators to assess it across organizational types. To contribute toward further theorization, this study problematizes scientization in international organizations, with a focus on multilateral, intergovernmental organizations. The study is organized around answering this overarching question: What are the conceptual and methodological attributes or features of scientization in international organizations? Using sociological theories and conceptions of policymaking and transfer, it discusses core substantive, methodological, and theoretical issues of scientization having relevance for further research.

Published: October 2021

Over the last few years, private and public organizations have suffered an increasing number of cyber-attacks owing to excessive exploitation of technological vulnerabilities. The major objective of these attacks is to gain illegal profits by extorting organizations which adversely impact their normal operations and reputation. To mitigate the proliferation of attacks, it is significant for manufacturers to evaluate their IT products through a set of security-related functional and assurance requirements. Common Criteria (CC) is a well-recognized international standard, focusing on ensuring security functionalities of an IT product along with the special emphasis on IS design and life-cycle. Apart from this, it provides a list of assurance classes, families, component, and elements based on which security EALs can be assigned to IT products. In this survey, we have provided a quick overview of the CC followed by the analysis of country-specific implementation of CC schemes to develop an understanding of critical factors. These factors play a significant role by providing assistance in IT products evaluation in accordance with CC. To serve this purpose, a comprehensive comparative analysis of four schemes belonging to countries including US, UK, Netherlands, and Singapore has been conducted. This comparison has aided to propose best practices for realizing an efficient and new CC scheme for the countries which have not designed it yet and for improving the existing CC schemes. Finally, we conclude the paper by providing some future directions regarding automation of the CC evaluation process.

Authors: Sirichoat Auttawit , Kham-ngam Irin , Kaewprasert Orawee , Ananta Pimjai , Wisetsai Awat , Lekphrom Ratsami , Faksri Kiatichai
Published: October 2021

Background

Infection withMycobacterium abscessusis usually chronic and is associated with clarithromycin resistance. Increasing drug resistance is a major public-health problem and has led to the search for new antimycobacterial agents. We evaluated the antimycobacterial activity, toxicity, and synergistic effects of several plant secondary metabolites againstM. abscessus.

Methods

Twenty-three compounds were evaluated for antimycobacterial activity against thirtyM. abscessusclinical isolates by broth microdilution to determine their minimum inhibitory concentration (MIC) values. Toxicity was evaluated using red and white blood cells (RBCs and WBCs). The compounds were used in combination with clarithromycin to investigate the possibility of synergistic activity.

Results

Five out of twenty-three compounds (RL008, RL009, RL011, RL012 and RL013) exhibited interesting antimycobacterial activity againstM. abscessus, with MIC values ranging from <1 to >128 μg/mL. These extracts did not induce hemolytic effect on RBCs and displayed low toxicity against WBCs. The five least-toxic compounds were tested for synergism with clarithromycin against seven isolates with inducible clarithromycin resistance and seven with acquired clarithromycin resistance. The best synergistic results against these isolates were observed for RL008 and RL009 (8/14 isolates; 57%).

Conclusions

This study demonstrated antimycobacterial and synergistic activities of pure compounds extracted from medicinal plants against clarithromycin-resistantM. abscessus. This synergistic action, together with clarithromycin, may be effective for treating infections and should be further studied for the development of novel antimicrobial agents.
Contribution to the bryoflora of Australia, V. Radula tonitrua sp. nov. from Queensland
Authors: Pocs Tamas , Renner Matthew AM
Published: October 2021

Further study of the two geographic lineages within Radula novae-hollandiae sens. lat. have resulted in the detection of morphological differences among individuals from the Queensland Wet Tropics, and those from New South Wales. Individuals from the Wet Tropics have perianths that are shorter at maturity (1.6-2.0 v. 3.8-4.4 mm), leaf lobes that usually bear numerous marginal gemmae, and leaf-lobules that are smaller and more quadrate. The morphological differences, particularly in perianth length, were not fully appreciated previously and provide evidence supporting the recognition of the Queensland Wet Tropics lineage as a distinct and new species, Radula tonitrua, which is here described. The degree of phylogenetic divergence and fixed molecular difference between R. tonitrua and R. novae-hollandiae, are comparable with the separation observed between R. ocellata and R. pulchella, another species pair exhibiting the same geographic disjunction.

The primary purpose of this study is to explore parental involvement in the academic achievement of primary students in Nigerian schools and to assess parental involvement at the Primary School level and how it enhances academic achievement. The researcher chooses the qualitative research method for this study and makes use of Semi-structured interviews to collect data on the first-hand experiences of two international post-graduate (PG) students at International Islamic University Malaysia (IIUM). The major finding of this study is parental involvement with their children. The Parents went to school to communicate with the class teacher and also they assisted with their children’s homework at their residential premises. Parents had high expectations of their children’s academic achievement in the class. There were some differences in the way the two parents were involved in the academic work of their children. This is because of some causes such as lack of time, new subject matter and distance to the schools. The findings of this study have implications mostly for teachers, teacher educators and educational decision-makers.

Each year, an estimated number of 300–500 million people are infected with malaria parasite, with an undesirable effect of over one million deaths. Pregnant women as well as young children, non-immune travellers visiting malaria-endemic zones are at the highest risk of suffering or experiencing life - threatening malaria infection. Maternal immunity, parasite density, parity, inadequate antenatal care services, drug misuse and abuse as well intermitted preventive treatment drug failure cum resistance are the most associated risk factors of malaria in pregnancy obtainable in endemic regions of sub-Saharan Africa. Identification and understanding of these factors will play a major role in reducing the burden as well as eliminating malaria disease among pregnant women living in endemic regions.

Background: Effective pain control in Total knee arthroplasty (TKA) is important for optimizing the rehabilitation process in order to achieve patient satisfaction with a good functional outcome as well as reduce hospitalization duration and costs. Combined use of aesthetic with tramadol has been reported to achieve a longer duration of sensory and motor block. The aim of this study is to evaluate the quality and duration of postoperative analgesia produced by ultrasound guided femoral nerve block (FNB) by bupivacaine versus (bupivacaine & tramadol) in patients undergoing total knee arthroplasty under spinal anesthesia.

Methods: This prospective randomized controlled double blinded study was carried out on 60 patients aged above 50 years; American Society of Anesthesiologists physical status (ASA) I-III scheduled for total knee arthroplasty under spinal anesthesia. Patients were randomized to one of two equal groups: Group I control (C): received FNB with 30 ml 0.25% bupivacaine. Group II tramadol (T): received FNB with 30ml 0.25% bupivacaine and 100 mg tramadol.

Results: Postoperative heart rate was significantly increased in group C than group T at 8h, 12h, 16h and 24h. Postoperative mean arterial blood pressure was significantly increased in group C than group T at 6h, 8h, 12h, 16h and 24h. There were 30 (100%) patients required rescue analgesia in group C and 19 (63.33%) patients in group T which was increased significantly in group C than group T. The time to first analgesic requirement was significantly decreased in group C than group T. Total morphine consumption was increased significantly in group C than group T. VAS was increased significantly in group C than group T at 6, 8, 12, 16 and 24 hours. Adverse effects were insignificantly different between both groups.

Conclusion: Adding tramadol (100 mg) to 0.25% bupivacaine (to a volume of 30 ml) during US guided FNB of TKA under spinal anesthesia was associated with better postoperative analgesia when compared with 0.25% bupivacaine alone.

The main objective of the Suspension of a vehicle is to maximize the contact between the vehicle tires and the road surface, provide steering stability and provide safe vehicle control in all conditions, evenly support the weight of the vehicle, transfer the loads to springs, and guaranteeing the comfort of the driver by absorbing and dampening shock. This paper discusses the kinematic design of a double a-arm Suspension system for an FSAE Vehicle. The hardpoint’s location can be determined using this procedure to simulate motion in any kinematic simulation software. Here, Optimum Kinematics is used as kinematic simulation software, and the results are verified using Msc Adams simulation. The method illustrated deals with the basics of Kinematics which helps to predict the characteristics of the Suspension even before simulating it in the kinematic simulation software.

Aim: The present research work was carried out to develop Valsartan and Amlodipine capsules using micro tablets and to evaluate the in-vitro drug release characteristics. The study was targeted to determine the systemic concentrations using in-vivo prediction.

Study Design: The in vivo parameters along with the marketed Valsartan and Amlodipine product was predicted using WinNonlin® software external prediction method.

Place and Duration of the Study: The present work was carried out at Pacific Academy of Higher Education and Research University, Udaipur between the duration of February-2019 to November-2019.

Methodology: The dissolution studies were performed for test and reference products in 900ml Phosphate buffer (pH 6.8), and the USP Type II apparatus at 50 RPM with a sinker. The in vivo pharmacokinetic prediction was performed using WinNonlin® Software. A mechanistic oral absorption model was built in Phoenix® WinNonlin® 8.2 software (Certara, Princeton, NJ, 08540, USA).

Results: The in-vitro dissolution studies were comparable between the test product and the reference product. The Similarity factor achieved was 61.7 and 84.8 for Amlodipine and Valsartan test product in comparison with the reference product. An average percent prediction error for Cmax and AUC for both Valsartan and Amlodipine achieved was less than 10% for all IVIVC models.

Conclusion: The relatively low prediction errors for Cmax and AUC observed strongly suggest that the Valsartan and Amlodipine IVIVC models are valid. The average percent prediction error of less than 10% indicates that the correlation is predictive and allows the associated dissolution data to be used as a surrogate for bioavailability studies.

Published: October 2021

By knowing the level of knowledge of patients about risk factors of dialysis induced hypertension, we will be able to be aware that the patients reduce the risk factor affecting dialysis induced hypertension patients undergoing maintenance hemodialysis. So, the objective of the study were to assess the knowledge and prevalence of dialysis induced hypertension among patient’s undergoing maintenance hemodialysis. A qualitative research study was used. The participants was all the dialysis induced hypertensive patients undergoing maintenance haemodialysis, data collection was done using a questionnaires and checklist, 100 were completed the data. Data were analysed by descriptive and inferential statistics. And according to statistical analysis results, there was no significant relationship between the knowledge and risk factor of dialysis induced hypertension patients.

Background: Intradialytic hypertension is an increase in blood pressure during or immediately after hemodialysis which results in post-dialysis hypertension, is often largely ignored. Patients undergoing hemodialysis will possibly raise blood pressure, because the role of the kidneys in blood homoeostasis is impaired, risk factors like chronic volume overload and a range of other risk factors might also contribute to high blood pressure.

Objectives: The objectives of this study were as follows, 1. Assess the knowledge and prevalence of dialysis induced hypertension among patients undergoing haemodialysis.

Find out the association between risk factors and knowledge of dialysis induced hypertension among patients undergoing haemodialysis.

Results: The clinical significance of dialysis induced hypertension lies in the fact that each of these possible risk factors may contribute to the development of dialysis induced hypertension, out of 100 participants 4 (4%) were in the age group of 21 to 30 years, 16 (16%) were in the age group of 31 to 40 years, 36 (36%) were in the age of 41 to 50 years, 44 (44%) were in the age group of the year above. As regard Gender, 63 (63%) were male and 37 (37%) were females. As regards 92 (92%) were Married and 08(08%) were Unmarried. Regarding prevalence 50 (50%) had hypertension before and 50 (50%) had hypertension after the dialysis. Out of 100 patients, all 100 samples were had increased dry weight, 13 were had volume overload, 77 were had poor dietary salt restriction, 24 were had a family history of hypertension, nil have pulmonary oedema, 03 were had hyperthyroidism, 15 were had diabetes, 04 were had the cardio vascular disorder, 08 were had anaemia. Out of the 100 samples, 15% of the samples had poor, 85 % of the samples had average knowledge on dialysis induced hypertension. Thus, dry weight was present in the entire patient undergoing hemodialysis. Descriptive statistics were used to assess the mean, frequency and percentage, inferential statistics like the Chi-Square test was used to test for association.
