The paper attempts to off-set the circuit parasitics and the inherent switching nature of the power switch in a SEPIC (Single Ended Primary Inductance Converter) that eclipses its performance from theoretical predictions. The focus orients to design a control strategy that offers a chaotic free operation of the SEPIC. It envisages the use of a Variable Structure Control (VSC) strategy to irradiate the adverse effects of non-linear dynamics and assuage the operating range of the converter. The scheme projects the creation and elimination of this nonlinear property through time domain waveforms and phase portraits. The methodology underscores the theory to ensure an uniform rate of charging and discharging for the inductor current during the process of the converter operating the load. The scheme realizes the benefits of the mechanism through a correlation between the open and closed loop inductor current time domain waveform, with the help of adjustments in the parametric variations. The effort involves evaluating the performance using MATLAB simulation and experimental validation in a DSPIC (Digital signal peripheral interface controller) environment to illustrate its suitability for practical applications.

Today international on-line content material has turned out to be a first-rate part due to growth in the use of net. Individuals of various societies and instructive foundation can speak through this platform. Therefore, for automatic detection of poisonous content, we need to distinguish between hate speech and offensive language. Here a way to robotically stumble on and classify tweets on Twitter into 3 commands: hateful, offensive and easy is proposed. We do not forget n-grams as functions and by way of passing their time period frequency-inverse document frequency (TFIDF) values to numerous system gaining knowledge of fashions using Twitter dataset, we perform comparative evaluation of the models. We work towards classification and comparison of different classifiers using the combination of best feature from each type of feature extraction and determining which model works best for the purpose of classification of tweets into hate-speech, offensive language or neither.

This paper proposes a new system which can be used to make short distance transactions Offline. The method discussed in this paper provides an in depth explanation of the project and how TOTP (Time-Based One Time Password) is used to carry out authentication which is completely offline. This idea is implemented since there is no current system which facilitates offline payments to occur. The project uses various functions such as Hashing (using SHA-1) and Audio QR to ensure security while it works offline. The project employs a QR code which encodes the user’s ID, TOTP token and the amount to be transferred to the receiver. The receiver then scans the QR code and decodes the contents, authenticates the user, checks the balance, if it is sufficient then the transaction occurs successfully. This system can be used in different scenarios such as shopping, travelling, restaurants etc.

In this study, computer-aided detection (CADe) system is optimized to reduce radiologists’ workload and to improve accuracy of cancer detection by providing more quantitative (objective) decisions added to the qualitative (subjective) assessment of radiologists. The images have been collected from MIAS database. 3 databases were prepared by 3 different ROIs sizes (32x32, 42x42 & 52x52 pixels). Then, prepressing is done to enhance the peripheral of ROIs. This CADe computed parametric features from ROIs using statistics, histogram, GLCM and wavelet techniques. Sequential Forward Selection (SFS) technique is used to study the significance of features and eventually to omit redundancies. Several types of K-Nearest Neighbor (KNN) and Support Vector Machine (SVM) classifiers were trained to differentiate between normal and abnormal ROIs, then tested on another non-training set. Best overall performance results obtained with ROI size of 32x32 and histogram of 32 levels (Accuracy = 97.37%, Sensitivity= 95%, Specificity = 100%, PPV = 100% and NPV = 94.74). The results also indicate some useful features are well-representing to abnormalities across different classifiers such as: Mean, STD, Square of STD, Mode, Median, Quantile (10%), Quantile (70%), Quantile (90%), Percentile (30%), throughout multiple histogram levels both in spatial and DWT spaces.
Serotonin in the elderly
Authors: Greeff OBW
Published: July 2020

Serotonin is said to determine our emotions, moods and affect. The physiology of serotonin implies it in the regulation of biological functions in line with our mood, like accelerated heart rate and sweating triggered by feeling flustered. Serotonin has multiple pharmacological actions in the body and alterations in serotonergic function may account for behavioural disturbances commonly observed in the elderly. The clinical effectiveness of selective 5-HT reuptake inhibitors (SSRIs) is believed to be mediated through enhancement of extracellular 5 HT. Various studies have shown that the SSRIs are better tolerated in older people compared with the tricyclic antidepressant or serotonin-norepinephrine reuptake inhibitors (SNRIs). It is obvious that serotonin plays a significant role in the emotional wellbeing of people – whether they are young or old and there are various ways of increasing serotonin in the body in order to create a feeling of wellbeing and content.

Construindo sentidos sobre o cuidado em saúde à luz da hermenêutica gadameriana
Authors: Deluque Júnior Romano , Costa Márcio Luís
Published: July 2020

Uma contribuição relevante da hermenêutica de Hans-Georg Gadamer para o tema do cuidado concentra-se sobre uma ótica que vislumbra as subjetividades que permeiam o adoecimento humano. Dentro desta perspectiva hermenêutica, as pessoas, além de seres biológicos, são também sujeitos de sua própria subjetividade, e como tais, vivenciam a experiência do cuidado a partir de suas próprias lentes afetivo-subjetivas. O presente estudo pretende ser um ensaio de discussão teórica, que intenta a construção de uma discussão que gere novos sentidos para o tema do cuidado em saúde à luz da Hermenêutica Filosófica de Hans-Georg Gadamer. Para tal, foram utilizados textos do próprio Gadamer (1997; 2002; 2011), assim como publicações de autores que trabalham a temática a partir do mesmo marco teórico. Para Gadamer (1997), os conhecimentos técnicos são obtidos através do estudo e da experiência, já sua correta aplicabilidade, somente será alcançada através do contato hermenêutico-experiencial junto a outra pessoa. E nesse sentido, o diálogo parece constituir uma dimensão decisiva para o estabelecimento de uma relação de abertura e igualdade. Além disso, a medicina baseada em evidências simplesmente não é, por si só, suficiente para prestar um cuidado atencioso e pautado nas peculiaridades subjetivas humanas.

La función del modelo de “comunicación casino” en la crisis del sistema neoliberal contemporáneo
Authors: Esteinou Madrid Javier
Published: July 2020

El modelo de “economía casino” que originó la crisis económica contemporánea en el año 2008, funcionó gracias a que construyó un modelo de “comunicación casino” que promovió los valores bárbaros del capitalismo salvaje y fomentó la compra de “inversiones basura”, derivados financieros de alto riesgo y productos bursátiles tóxicos paralelos que durante varios años generaron dicho modelo especulador. Por ello, la verdadera corrección de tal hundimiento económico no se arreglará con la simple inversión financiera de los Estados nacionales, sino que se solucionará con el saneamiento profundo de las raíces ético morales que lo originaron.

Patal - Pusri Intersection is one of the intersections in Palembang with heavy traffic flow and frequent traffic jams. The existence of Underpass construction, apparently could not be a complete solution to unravel traffic congestion. The purpose of this research is to analyze five alternative scenario plans to disentangled the vehicle density, congestion, and reduce pollution from exhaust emissions caused by vehicle density. This research was conducted using VISSIM Microsimulation Program assistance to simulate existing alternative scenarios and to analyze the effect of these alternative scenarios on reducing vehicle exhaust emissions using the EnViVer Program assistance. The results showed that the fifth alternative scenario as the flyover construction, geometric changes at the intersection’s leg crossing, and traffic lights rearrangement became the most effective alternative and was able to parse vehicle density and traffic congestion, and was able to reduce exhaust emissions by 32.36%. This was shown by the reduction in queue length by 44% and the delay times by 57.05%, and the reduction in exhaust emissions in the form of carbon dioxide (CO2) by 35.5%, nitrogen oxides (NOx) by 43%, and particulate matter (PM10) ) by 18.6% at the intersection significantly.

Mycological research in the Northern part of West Siberia has now become sufficient for review and digitisation as over 460 scientific works have been completed mainly since the beginning of the 20th century. The history of research in the region started from isolated studies at the beginning of the 20th century, but regular and systematic research started from the 1970s. Over the following decades, several dozens of researchers have worked in the area, but the reported occurrences were scattered amongst a broad variety of publications, mainly hardly available. The great need in digitisation and accumulation of fungal records reported in published literature in a standardised regional database has now become evident. The «Fungal records database of the Northern West Siberia» (FuNWS) was initiated in 2016 according to contemporary biodiversity data standards (Darwin Core), to be compatible and accessible by the broad research community. The database has been supplemented ever since by the collective effort of specialists working in the area. According to the database summary report, there are 3358 fungal and fungus-like species revealed in the Northern West Siberia at present. The richest in species number classes are Agaricomycetes (60%) and Lecanoromycetes (33%) with a total of 25 classes represented. The FuNWS database was uploaded to Global Biodiversity Information Facility (GBIF) (Ygra State University Biological Collection publisher) on 11 November 2017 (earlier titled «Fungal Records Database of Yugra, FReDY») to provide open access to the data and its reusability (Filippova et al. 2020).

This publication summarises the results of the digitisation of literature-based occurrence records of fungi and fungus-like organisms initiated in the Northern part of West Siberia for the first time in the history of mycological research. The bibliography of regional mycological publications was created to include about 460 published works (Suppl. material 2). In total, about 140 literature sources were digitised and about 22000 occurrence records were integrated into the FuNWS database (Filippova et al. 2020).
Preventing Social Isolation: A Holistic Approach to Nursing Interventions
Authors: Gale Anna
Published: July 2020

The current need for social distancing due to the COVID-19 pandemic can lead to social isolation in the older adult population. Social isolation contributes to multiple health problems for older adults residing in the community and residential care facilities. Mitigating the effects of social isolation requires a holistic approach, focusing interventions on the physical, psychological, and psychosocial needs of older adults. Nurses possess a unique expertise in developing holistic interventions and using creativity to counteract the negative health sequelae resulting from social isolation. The nursing role in holistic care serves to protect the older adult's ego integrity, improve quality of life, and maintain wellness during this time of mandated social distancing. [

Determination of the stability of osmium(IV) hexachloride ICP-OES standards in HCl acid matrix
Authors: T. Chiweshe Trevor , Atangana Abdon , Deysel Lore-Mari
Published: July 2020

The ideal HCl concentration used in stabilizing osmium standards was investigated in this study. Additionally, mathematical models were tested to predict the decomposition rate of osmium standards at room temperature. Osmium(IV) hexachloride stock solutions stabilized in 7 and 15% HCl were used to assess the decomposition rate using ICP-OES. Several sets of calibration standards were prepared from the original stock solutions. The first calibration set was prepared with no additional HCl added to the final solutions and other sets with a total HCl acid concentration of 0.2, 0.4, 0.6, 1.0 and 1.5% v/v. Emission intensities were measured at 0, 24, 48, 72 and 96 hours. Standards with no additional HCl acid added kept at room temperature showed increase in emission intensities after 24 hours. These changes in emission intensities indicated chemical instability of osmium standards at low acid concentration levels. Standards stabilized in 1.0–1.5% HCl and refrigerated below 10 ⁰C showed consistent emission intensities and had a shelf life of up to 48 and 72 hours, respectively.  Four mathematical models were tested to determine the decomposition rate of the osmium standard. The first used rate of change concept and the second a stochastic approach. Both failed to capture osmium decay. The third was based on non-local operators with power law kernel and was able to capture the decay at earlier, but not later stages. The fourth, based on non-local operators with non-singular kernel was able to capture earlier and later decay due to its crossover properties in waiting time distribution.

Influence of NiO nano-flakes dispersion on the viscosity of lubricating oil
Authors: Sundaram C. Mathalai , Rajesh A. Vembathu , Sivaganesan V.
Published: July 2020

Protecting interacting surfaces of mechanical systems against friction and wear have a wide range of industrial applications. Viscosity is the supreme property of any lubricant which overpowers viscous drag in hydro-dynamically lubricated mechanical systems. The dispersion stability of NiO-nanolubricants is achieved by ultrasonication technique. The detailed study of the viscosity of NiO nano-flakes dispersed in SN500 lubricants with weight fraction of 0.25-1.5% was performed in the temperature between 40-90 °C. The results show that increasing the weight fraction of NiO nano-flakes resulted in consistence viscosity increment. Further, the measured viscosity is compared with different concentration and temperature dependent theoretical models. On the basis on experimental viscosity data a theoretical correlation is recommended to predict the viscosity of NiO-nanolubricants with less than 5% margin of deviation.

Background: To compare the pattern of vaginal microflora during pregnancy with pattern in early labour using Nugent scoring and determine the effect of these changes on fetal outcome.

Design: A prospective longitudinal study.

Setting and Population: Pregnant women attending antenatal clinics of Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria between June 2017 and May 2018.

Methods: Consenting pregnant women who attended antenatal clinics were recruited. Vaginal secretions were obtained for Nugent scoring during pregnancy and at presentation in labour.

Main Outcome Measures: Prevalence of abnormal vaginal flora in pregnancy and early labour, birth outcome, birth weight, gestational age at delivery, APGAR scores, need for neonatal ward admission.

Results: Sixty-seven (33.3%) of pregnant women had abnormal flora which was consistent with bacterial vaginosis.At the presentation of these women in labour, 14.4% of them had bacterial vaginosis thus indicating a significant reduction in abnormal vaginal flora in labour compared to the proportion of abnormal flora in antenatal period(P<0.001). There were no significant differences in the fetal outcomes of mothers with bacterial vaginosis when compared with those with normal vaginal flora (P-value >0.05).

Conclusions: Persistence of abnormal vaginal microflora from pregnancy till early labour did not seem to be associated with poorer foetal outcomes when compared with women with normal vaginal microflora in labour. The possibility of persistent infection or re-infection before labour may justify the need for re-evaluation of vaginal smears in the late third trimester to allow for prompt treatment before the onset of labour.

Keywords: Bacterial vaginosis, foetal outcome, Lactobacillus, pregnancy, vaginal microflora.

At the 2007 TrustAfrica workshop in Dakar, the conference of religious leaders, scholars, and experts from 12 African countries and the Diaspora explored this concern under the theme "Meeting the Challenges of Religion and Pluralism in Africa." It was observed that religiously justified conflicts were often the repackaging of community concerns regarding issues of social, economic, and political injustices, inequities and exclusions. Consequently, a project on “religious pluralism and interfaith coexistence in Ghana” was funded in 2008 as part of the efforts to examine the role of local traditions as a foundation to interfaith dialogue. Earlier in 2005, a similar project on the theme of Islam and tolerance, with funding from Harvard and Michigan State University, was conducted in Ghana. Several issues emerging from the field conversations are pertinent to topics of how history shaped Muslim relations with their non-Muslim hosts in West Africa. It is often argued in the literature that Islam’s inherently adoptive attitude toward African religious culture made it possible for Muslims and their non-Muslim hosts to co-exist. However, this research contends that, in the case of Ghana, it was the traditional local culture as defined by indigenous religious values that shaped and moderated the environment that sustained peaceful interreligious relations. The authors express concern that as the country experiences rapid urbanization, Westernization, proliferation of charismatic churches and aggressive Christian evangelization, the traditional values that underpinned pluralism and peace in historic times might be threatened (George Bob-Milliar and Karen Lauterback, 2018).

Published: July 2020

This paper uses Q Methodology to ascertain the views of project staff on how they could be involved in evaluation in order to enhance process use.  Structured interviews were conducted with twenty-five project staff who participated in two project evaluations within the context of participatory evaluation in Ghana. It emerged that the use of Q Methodology in evaluation studies enhances the mainstreaming of process use by helping to focus on the critical issues in participatory evaluation practice. Process use is enhanced when ample time is provided for intensive interaction with evaluation stakeholders from the formative stage of evaluation. Process use also requires evaluators to create an environment that is supportive of mutual interaction and closeness in working relations with stakeholders. The research concludes that process use in evaluation is attained through well-planned evaluation that gives voice to project staff and emphasises shared learning. The study recommends critical attention to active participation of project staff, group processes and shared learning, if process use is to be achieved by evaluation. Further research is needed to clarify which form(s) of stakeholder involvement in evaluations contributes more positively to process use.
Comparison of Cation Anion Dye Removal Characteristics between Kelp-based Magnetic Biochar and Pine-based Magnetic Biochar
Authors: Oh Hee So , Chang Jae-Soo
Published: July 2020

Objectives:This study investigates the adsorption capacity of magnetic biochar (KB-Fe) derived from kelp for two dyes, Congo red (CR) and crystal violet (CV), which have different charge characteristics. The adsorption capacities were compared to magnetic biochar (PB-Fe) derived from pine.Methods:Pristine biochars (KB, PB) were produced through the pyrolysis of kelp and pine sawdust at 500℃. Magnetic biochars (KB-Fe, PB-Fe) were produced by treatment of 60 g of biomass in 1 L of 0.1 M FeCl3･6H2O and pyrolysis of the raw materials at 500℃. The fundamental characteristics of the biochars were analyzed, and the adsorption capacities of the biochars for the CR and CV dyes were evaluated based on two adsorption isotherm models, two adsorption kinetics models, and adsorption characteristics based on changes to the pH between 5 and 11.Results and discussion:CR adsorption by all biochars decreased with an increase in pH. When KB and PB were surface-modified with magnetic iron oxides, their adsorption capacity for CR increased. CV adsorption by all biochars increased with pH. When KB and PB were surface-modified with magnetic iron oxides, their adsorption capacity for CV considerably decreased. According to the Langmuir isotherm model, the adsorption capacity for CR was in the order of KB-Fe, KB, PB-Fe, and PB, and the adsorption capacity for CV was in the order of KB, PB, PB-Fe, and KB-Fe. The CR adsorption was better described by the pseudo-second order kinetics model for all biochars, with the exception of KB-Fe. CV adsorption was also better described by the pseudo-second order kinetics model for all biochars, with the exception of KB.Conclusions:The results show that kelp biochar has great potential for the adsorptive removal of CR and CV compared to pine-based biochar. In addition, it was demonstrated that surface modification of kelp biochar with magnetic iron oxides can significantly improve its adsorptive capacity for anionic dyes; however, its adsorptive capacity for cationic dyes decreases.
The COVID-19 Pandemic, Donald Trump, and the Future of American Politics
Authors: Korobkov A. V.
Published: July 2020

The United States of America was disproportionally severely affected by the COVID-19 pandemic. The current crisis exposed significant flaws in the national health care system and provoked a serious socio-economic crisis. The health care scare overlaps with the ongoing presidential electoral campaign and the extreme political polarization of the country, leading to the politicization of discussions regarding the ways and means of resolving the health care crisis and complicating the process of decision making. The pandemic is also enhancing the autarchic tendencies in the US foreign policy and it’s the increasingly anti-Chinese orientation that became visible during Donald Trump’s White House tenure. Even under these circumstances, the American elites were able to negotiate several stabilization measures designed to deal with the medical and socio-economic aspects of the current crisis. Their willingness and ability to continue such collaboration in the future will have a direct bearing on the US socio-economic and political stability.
School and community. The Colombian experience with Student Social Service Projects.
Authors: Ortega Torres W. Eduardo , Vahos Anaya M. Alejandra , Sánchez Medina José Antonio
Published: July 2020

One of the most difficult problems that the school is currently facing is that it generates encapsulated knowledge and learning processes that are disarticulated from the characteristics of the context which defines students. Against this background, it is proposed that learning- service can become an alternative that manages to articulate the knowledge of the school with the community in order to generate authentic learning processes. Based on these premises, this article presents a practical study on Student Social Service Projects (SSSP), as an alternative to overcome the dualistic school-community vision. The SSSP is a state requirement that every student from public or private education in Colombia must meet in the upper grades and which, from the theory, is recognized as a scenario of articulation between the school, the community, and the individual. However, the findings show a series of difficulties that have limited its educational scope and reveal a historically fragmented and lacking national educational system, from which the school needs to be rethought and re-signified to strengthen the learning and training processes of students.
Empresas multinacionales y derecho a la seguridad social
Authors: Del Valle Villar José Manuel
Published: July 2020

El derecho a la seguridad social, recogido en textos internacionales como la Declaración Universal de Derechos Humanos, no ha obtenido reconocimiento general. Su evolución difiere en los diversos sistemas de seguridad social. En los ordenamientos de los países europeos (en general occidentales), consigue su máxima extensión subjetiva y objetiva. No ocurre lo mismo en los ordenamientos de los países en desarrollo. Las obligaciones que unos y otros sistemas imponen a las empresas son distintas, cualitativa y cuantitativamente. Esta diversidad por un lado beneficia a las empresas multinacionales, pero por otro provoca importante desprotección de los trabajadores cuyos derechos se desconocen (vida, integridad física, dignidad, suficiencia salarial, trabajo…). En la monografía se examinan en primer lugar las debilidades de los instrumentos jurídicos de que disponemos para exigir responsabilidades a las empresas multinacionales por la concurrencia de las contingencias protegidas habitualmente por los sistemas de seguridad social; en segundo lugar, se plantea el nivel de compromiso que puede modernamente imponérseles con respecto al desarrollo de tales sistemas. Asimismo, se trata en ella de proponer soluciones a esas insuficiencias detectadas través de actualizar la institución de la responsabilidad jurídica, de reinterpretar el principio de solidaridad sobre el que se erige el tan citado derecho a la seguridad social y de examinar las posibilidades que a estos efectos ofrece la llamada responsabilidad social de las empresas (RSE).

Published: July 2020

El uso de datos en los ámbitos de derechos humanos es cada vez más habitual. Los indicadores han ido adquiriendo mayor relevancia e implantación, especialmente en la labor de los organismos internacionales y en las herramientas de protección de los derechos económicos, sociales y culturales. El objetivo de este trabajo es dar respuesta a la pregunta: ¿qué pueden aportar los indicadores a los derechos económicos, sociales y culturales y especialmente a su exigibilidad?; a través del análisis de cómo deben ser, qué pueden aportar y dónde. De otra forma: sus requisitos, sus potencialidades y sus contextos. El objetivo final es poner en valor la importancia de los datos y las estadísticas en la defensa y la protección de los derechos económicos, sociales y culturales y, sobre todo, este trabajo aporta una visión concreta y práctica del uso de indicadores en los informes periódicos ante instituciones internacionales y en los mecanismos de denuncia.
Caminhada da Fé: uma hermenêutica da devoção mariana à Aparecida
Authors: Almeida Rosiléa Archanjo de
Published: July 2020

O presente artigo apresenta a peregrinação a pé feita por fiéis da cidade de Juiz de Fora à Aparecida (SP), onde localiza-se o Santuário Nacional em honra à Nossa Senhora da Conceição Aparecida, considerada pelos católicos, a padroeira do Brasil. Analisamos os discursos dos peregrinos juiz-foranos e de outras cidades que percorrem o trajeto de aproximadamente 300Km na chamada “Caminhada da Fé”. Os peregrinos enfrentam no percurso, adversidades, como calo nos pés, cansaço corporal e mental. Sabendo de tais condições, nos questionamos: o que motiva os devotos a participar desta Caminhada? Para chegar aos objetivos deste artigo, analisamos os discursos dos caminhantes, a partir da série “Fé na Estrada”, publicada no jornal impresso Tribuna de Minas, e em suas mídias sociais. A fé é apresentada como o principal motivo para a participação na Caminhada, entretanto, observamos que além da fé, a pertença a um grupo social estimula a participação na Caminhada da Fé.
Como se forma um professor de Educação Física? Análises sobre a formação humana, o currículo e a formação docente
Authors: De Souza Bárbara Isabela Soares
Published: July 2020

O presente estudo realiza uma análise dos conhecimentos selecionados para compor o currículo dos cursos de Licenciatura Presencial em Educação Física, os quais são ofertados por cinco IES localizadas em Goiânia-GO, explicitando as relações de hegemonia estabelecidas entre as disciplinas que compõe os mesmos. Para desenvolver tal investigação, foram realizadas discussões teórico-conceituais sobre as concepções de ser humano e sociedade da filosofia materialista histórico-dialética e a Teoria Histórico-Cultural. Ademais, tratamos sobre o processo histórico de constituição dos cursos de formação docente em Educação Física, enfatizando os modelos curriculares que os caracterizaram. A análise dos conhecimentos selecionados para compor os currículos dos cursos de formação de professores em Educação Física, aponta para uma hegemonia dos conteúdos relacionados à Ginástica e ao Esporte. Somando-se a isto, foram identificados indícios de uma desvalorização dos conteúdos referentes às Lutas e aos Jogos e Brincadeiras.
