Published: October 2021

Welding is one of the metal joining processes in manufacturing. CDFW (continuous drive friction welding) is a welding process to join two workpieces by applying pressure at one end of the object and rotating another one where the friction action applies at interface. The purpose of this study is to study temperature distribution on the surface of the welding area and the heat-affected zone represented by a fully plasticized zone (Zpl) and to get an insight of a friction welding process. The variables of CDFW used were double chamfer angle, upset pressure, and burn off length. The initial area of friction was equal that is at a diameter of 14 mm. The method of modeling the CDFW friction welding is via computer simulations using ANSYS 18.1 software. This research uses aluminum material type Al6061. The Taguchi method was applied in designing the simulations. In this modeling, the model with the double chamfer of 15 °, the upset pressure of 120 MPa, and the burn-off length of 9 mm has a small ZPl area of 10.256 mm2. Whilst the specimen model, with a double chamfer angle of 45 °, the upset pressure of 240 MPa, and the burn-off length of 7 mm has a large Zpl area of 56.55mm2. The area of a narrow fully plasticized area caused by small chamfer angle and an upset pressure of 240 MPa. The area of fully plasticized zone shows how much material can be integrated during the friction welding process and how much strength of the weld metal. The model with the chamfer angle of 15 º, the upset pressure of 240 MPa, and the burn-off length of 9 mm has the widest temperature distribution and the highest maximum temperature. Meanwhile, the model with the chamfer angle of 30º, the upset pressure of 120 MPa, and the burn-off length of 9 mm has the narrowest temperature distribution and the lowest maximum temperature. The smaller chamfer angle increased upset pressure and burn-off length result in the wider temperature distribution, higher maximum temperature, and smaller Zpl.

The results of a study of the effect of annealing at 150 °C in an inert atmosphere (Ar + 5% H2) on the electrical properties of organic field-effect transistors based on pentacene are presented. Crystalline pentacene films with a thickness of 95 ± 5 nm were obtained using thermal vacuum deposition. The transfer and output characteristics of field-effect transistors before and after annealing for 15 hours are investigated. It was found that as a result of heat treatment, the hole mobility in the saturation regime increased by an average of 30%, and the threshold voltage decreased approximately two times. According to the data of atomic force microscopy, annealing led to a more than twofold decrease in the surface roughness of pentacene films, as well as to a noticeable enlargement of grains, which led to a decrease in the concentration of traps for hole electric transport in the channel of the field-effect transistor.

We considered the problem of localization of electrons and holes taking for instance the pyramidal InAs quantum dots in GaAs. The problem of quantum mechanics was solved for the localizing potential taking into account the geometry, chemical composition and built-in fields of the mechanical stress and strain. We found that the strongest localization of both types of charge carriers can be achieved if the ratio of the pyramid height to its base is about 0.2.
Architecture of the Chilean Epidemiologic Surveillance System for Mandatory Reporting of Infectious Diseases: EPIVIGILA (Preprint)
Authors: Taramasco Carla , Rimassa Carla
Published: October 2021

UNSTRUCTURED

Epidemiologic surveillance incorporates technology to provide safe, fast and trustworthy digital solutions for the control of public health and is especially efficacious in the Mandatory Reporting of Infectious Diseases. These are listed according to international agreements and national norms. The enforceability of the declaration must be accompanied by adequate processes for a timely, clear, sure and true way, from the start when a consultant is met by a health professional (notifier) until the declaration is reported to the Health Authority so as to make decisions which will impact the public health of a territory. Among the processes used to fulfill this declaration are the manual mode or a totally technologized method. The aggressive propagation force of some diseases imposes incorporating technological advances to provide information in real time, so a manual method is discarded as it is absolutely inefficient. The purpose of this article is to describe the architecture of the EPIVIGILA platform for Mandatory Reporting of Infectious Diseases, detailing the database construction process, its technologic analysis and its impact in the control of Chilean public health. EPIVIGILA’s strengths are the quality of its data and therefore the credibility of the provided information. This is achieved by a set of validations that decrease or annul possible errors. Its usefulness is constantly tested, as new diseases or the re-emergence of others are unforeseeable and, therefore, as a living system, it requires a recursive, progressive and constant learning process.

Published: October 2021

BACKGROUND

In-patient management like ordering medical tests is time-consuming and burdens physicians on the ward with non-clinical tasks. We developed and implemented a smartphone-based mobile application (MA) that uses speech recognition for the ordering of radiological examinations. While we could show that the MA supported process was faster, its acceptance and usability remaines unknown.

OBJECTIVE

We examined the user experience (1), user acceptance (2) and the determinants of user acceptance (3) of a new mobile, speech recognition guided in-patient management MA.

METHODS

A comprehensive questionnaire based on the short version of the User Experience Questionnaire (UEQ-S) and the Unified Theory of Acceptance and use of Technology (UTAUT) was given to all physicians at the Department of Trauma and Plastic Surgery at the University Hospital of Wuerzburg , Germany. The user experience with the new MA was compared to the usual desktop application (DA) workflow embedded in the clinical information system (i.s.h.med, Cerner Health Services Deutschland GmbH, Berlin, Germany). The domains of user experience consisted of overall attractiveness, pragmatic quality, and hedonic quality. For the determinants of the acceptance model, we employed hierarchical regression analysis.

RESULTS

Twenty-one out of 30 physicians (mean age 34±8 years, 62% male) completed the questionnaire (response rate 70%). Compared to the conventional DA workflow, the new MA showed superior overall attractiveness (mean difference +2.15±1.33), pragmatic quality (mean difference +1.90±1.16), hedonic quality (mean difference 2.41±1.62; all p<.001). The user acceptance measured by the UTAUT (mean 4.49, SD 0.41; min. 1, max. 5) was also high. Performance expectancy (beta=0.57, p=.02) and effort expectancy (beta=0.36, p=.04) were identified as predictors of acceptance explaining 65.4% of its variance.

CONCLUSIONS

There is huge potential in reducing the physicians’ burden of administrative tasks by adopting innovative DHI like our speech recognition guided MA in daily ward routine. With this study, we could illustrate that physicians are more than willing to implement such innovative mobile health solutions.

Published: October 2021

BACKGROUND

COVID-19 vaccines are in short supply worldwide. China was among the first countries to pledge supplies of the COVID-19 vaccine as a global public product, and to date, the country has provided more than 600 million vaccines to more than 200 countries and regions with low COVID-19 vaccination rates. Understanding the public’s attitude in China toward the global distribution of COVID-19 vaccines could inform global and national decisions, policies, and debates.

OBJECTIVE

The aim of this study was to determine the attitudes of adults living in China regarding the global allocation of COVID-19 vaccines developed in China and how these attitudes vary across provinces and by sociodemographic characteristics.

METHODS

We conducted a cross-sectional online survey among adults registered with the survey company KuRunData. The survey asked participants 31 questions about their attitudes regarding the global allocation of COVID-19 vaccines developed in China. We disaggregated responses by province and sociodemographic characteristics. All analyses used survey sampling weights.

RESULTS

A total of 10,000 participants completed the questionnaire. Participants generally favored providing COVID-19 vaccines to foreign countries before fulfilling domestic needs (75.6%, 95% CI 74.6%-76.5%). Women (3778/4921, 76.8%; odds ratio 1.18, 95% CI 1.07-1.32; P=.002) and those living in rural areas (3123/4065, 76.8%; odds ratio 1.13, 95% CI 1.01-1.27; P=.03) were especially likely to hold this opinion. Most respondents preferred providing financial support through international platforms rather than directly offering support to individual countries (72.1%, 95% CI 71%-73.1%), while for vaccine products they preferred direct provision to relevant countries instead of via a delivery platform such as COVAX (77.3%, 95% CI 76.3%-78.2%).

CONCLUSIONS

Among our survey sample, we found that adults are generally supportive of the international distribution of COVID-19 vaccines, which may encourage policy makers to support and implement the distribution of COVID-19 vaccines developed in China worldwide. Conducting similar surveys in other countries could help align policy makers’ actions on COVID-19 vaccine distribution with the preferences of their constituencies.
Message Frame–Tailoring in Digital Health Communication: Intervention Redesign and Usability Testing (Preprint)
Authors: van Strien-Knippenberg Inge S , Altendorf Maria B , Hoving Ciska , van Weert Julia C M , Smit Eline S
Published: October 2021

BACKGROUND

Message frame–tailoring based on the need for autonomy is a promising strategy to improve the effectiveness of digital health communication interventions. An example of a digital health communication intervention is Personal Advice in Stopping smoking (PAS), a web-based content-tailored smoking cessation program. PAS was effective in improving cessation success rates, but its effect sizes were small and disappeared after 6 months. Therefore, investigating whether message frame–tailoring based on the individual’s need for autonomy might improve effect rates is worthwhile. However, to our knowledge, this has not been studied previously.

OBJECTIVE

To investigate whether adding message frame–tailoring based on the need for autonomy increases the effectiveness of content-tailored interventions, the PAS program was redesigned to incorporate message frame–tailoring also. This paper described the process of redesigning the PAS program to include message frame–tailoring, providing smokers with autonomy-supportive or controlling message frames—depending on their individual need for autonomy. Therefore, we aimed to extend framing theory, tailoring theory, and self-determination theory.

METHODS

Extension of the framing theory, tailoring theory, and self-determination theory by redesigning the PAS program to include message frame–tailoring was conducted in close collaboration with scientific and nonscientific smoking cessation experts (n=10), smokers (n=816), and communication science students (n=19). Various methods were used to redesign the PAS program to include message frame–tailoring with optimal usability: usability testing, think-aloud methodology, heuristic evaluations, and a web-based experiment.

RESULTS

The most autonomy-supportive and controlling message frames were identified, the cutoff point for the need for autonomy to distinguish between people with high and those with low need for autonomy was determined, and the usability was optimized.

CONCLUSIONS

This resulted in a redesigned digital health communication intervention that included message frame–tailoring and had optimal usability. A detailed description of the redesigning process of the PAS program is provided.

Published: October 2021

BACKGROUND

Little is known about family member involvement, by relationship status, for patients treated in the intensive care unit (ICU).

OBJECTIVE

Using documentation of family interactions in clinical notes, we examined associations between child and spousal involvement and ICU patient outcomes, including goals of care conversations (GOCCs), limitations in life-sustaining therapy (LLST), and 3-month mortality.

METHODS

Using a retrospective cohort design, the study included a total of 858 adult patients treated between 2008 and 2012 in the medical ICU at a tertiary care center in northeastern United States. Clinical notes generated within the first 48 hours of admission to the ICU were used with standard machine learning methods to predict patient outcomes. We used natural language processing methods to identify family-related documentation and abstracted sociodemographic and clinical characteristics of the patients from the medical record.

RESULTS

Most of the 858 patients were White (n=650, 75.8%); 437 (50.9%) were male, 479 (55.8%) were married, and the median age was 68.4 (IQR 56.5-79.4) years. Most patients had documented GOCC (n=651, 75.9%). In adjusted regression analyses, child involvement (odds ratio [OR] 0.81; 95% CI 0.49-1.34; P=.41) and child plus spouse involvement (OR 1.28; 95% CI 0.8-2.03; P=.3) were not associated with GOCCs compared to spouse involvement. Child involvement was not associated with LLST when compared to spouse involvement (OR 1.49; 95% CI 0.89-2.52; P=.13). However, child plus spouse involvement was associated with LLST (OR 1.6; 95% CI 1.02-2.52; P=.04). Compared to spouse involvement, there were no significant differences in the 3-month mortality by family member type, including child plus spouse involvement (OR 1.38; 95% CI 0.91-2.09; P=.13) and child involvement (OR 1.47; 95% CI 0.9-2.41; P=.12).

CONCLUSIONS

Our findings demonstrate that statistical models derived from text analysis in the first 48 hours of ICU admission can predict patient outcomes. Early child plus spouse involvement was associated with LLST, suggesting that decisions about LLST were more likely to occur when the child and spouse were both involved compared to the involvement of only the spouse. More research is needed to further understand the involvement of different family members in ICU care and its association with patient outcomes.

Authors: Han Mihwa , Lee Kyunghee , Kim Mijung , Heo Youngjin , Choi Hyunseok
Published: October 2021

BACKGROUND

The COVID-19 pandemic has presented a substantial burden on the global medical system. COVID-19-related restrictions on movement and face-to-face interactions to prevent the spread of infection have increased the risk for patients with schizophrenia being overlooked by medical professionals due to increased demands on staff and facilities. Therefore, application-based treatments and interventions developed for smartphones could provide effective and essential alternatives to traditional face-to-face treatment programs for patients with schizophrenia during the COVID-19 pandemic.

OBJECTIVE

This study aimed to test the effect of a smartphone app-based metacognitive intervention program on the metacognitive beliefs, psychotic symptoms, and social functioning of patients with schizophrenia.

METHODS

The study used a quasi-experimental design with a non-equivalent comparison group. Participants were patients with schizophrenia registered with community psychosocial rehabilitation centers. For the experimental group, the app-based intervention was combined with weekly contact mentoring sessions over 10 weeks (20 participants: severe psychotic symptoms and low social functions). The comparison group (24 participants: relatively light psychotic symptoms and good social functions) received only the app-based intervention over 10 weekly sessions. Changes in the Dysfunctional Metacognitive Beliefs (MCQ-30), Psychotic Symptom Rating Scales, Positive and Negative Syndrome Scale, and Personal and Social Performance Scale were assessed at baseline (pre-intervention), post-intervention, and four-week follow-up. Data were collected from November 18, 2020, until July 15, 2021. The data analysis was carried out using IBM SPSS/WIN version 26.0.

RESULTS

The experimental group showed a significant improvement in the Positive Beliefs about Worries on the MCQ-30, Need for Control (P = .039), and Delusions (P < .001), and the Total Score for positive and negative syndromes, along with a decline in general psychotic symptoms (P = .027) and improved total social function scores (P = .001) over the three assessment periods.

CONCLUSIONS

Although there were no differences in the measures between the two groups; however, the experimental group showed a tendency toward improved psychotic symptoms and social functioning over time; while the comparison group showed no change over the assessment periods. These findings can provide an empirical basis for using smartphone applications to manage the symptoms of patients with schizophrenia.

Many people choose alternative medicines for Diabetes Mellitus (DM) disorders, such as herbal plants to suppress the occurrence of the disease widely. In general, DM occurs when the pancreas doesn't produce enough insulin, or when the body can't effectively use the insulin which it produces. The use of medicinal plants to treat various diseases has shown minimal side effects. Indonesia is one of the countries that has used plants as traditional medicine since ancient times. In Indonesia, thousands of species of medicinal plants have been studied to address health problems. Among the medicinal plants that have been studied is the Neem plant (Azadirachta indica A. Juss) which has been shown to cure various diseases. This review article describes the potential of the Neem plant as an antidiabetic. The results of this literature review, in the form of Neem herbal extracts, have quite good potential as an antidiabetic because they contain several compounds such as meliacinolin, azachdirichtin, gliserid oil, acetyl oxyturanoe acid and other compounds that can also act as antidiabetic.

Food spoilage during storage occurs physically, chemically and biologically which is related to the activity of bacteria. One of the natural preservation that is currently developing is the application of edible coating on perishable food, such as fishball. Addition of antibacterial agent is important to improve edible coating. Virgin coconut oil contains medium chain fatty acids which have antimicrobial properties, particularly monoglycerides and free fatty acids that produced by hydrolyzing partially triglycerides at the Sn-1 and Sn-3 position using Lipozyme. The aim of this research was to test the effect of edible coating carrageenan enriched with virgin coconut oil hydrolysis (HVCO) (concentrations 1%,3%,5%) on fishball quality.The method was an experimental with factorial completely randomized design.The samples were analyzed for sensorial assessments, Total plate Count, Total Volatile Base-Nitrogen, Water content, and pH for 5 days at room temperature. The study demonstrated that fish meatball coated with carrageenan based-edible coating fortified with HVCO showed the best result compared to controls (Uncoated fishball, coated without HVCO). Sensory attributes were still accepted by panelists until 3 days. Meanwhile, the same pattern depicted by TPC and TVB-N parameters. HVCO5% had inhibited microbial growth and retarded the increase of TVB-N number on fishball, the results were Log 5,08cfu/gr, 29,69 mg/100 gr respectively.
"The Worst Place in the World for Women"
Authors: Niggeler Coralie Gaia
Published: October 2021

This paper explores the nature of conflict-related sexual violence committed by the State Armed Forces (FARDC) in the Democratic Republic of Congo, through the application of the general strain theory. Findings show that sexual violence committed by the FARDC is commonly used as a form of personal catharsis and emotional release from perceived strains, as opposed to resulting from sexual desires or external institutional pressures. Further, the most influential contextual elements present in the local context of the FARDC, and which particularly encourage the propagation of sexual violence, include female FARDC soldiers receiving desired military positions, the centrality of strains to personal notions of masculinity and aspirations, the dismantling of social cohesion through patronage networks, and a lack of behavioural coping options. In turn, these factors reduce the efficiency of non-criminal coping strategies. Hence, interventions aimed at reducing the propagation of conflict-related sexual violence may benefit from more bottom-up and inductive approaches improving the individual circumstances of soldiers as opposed to solely focusing upon organisational change and military reform.
The Import of Southern Criminology
Authors: Zimmermann de Meireles Philippi Ana Paula
Published: October 2021

Southern Criminology is a post-colonial movement of knowledge production that has political, empirical and theoretical facades. This article argues that the most significant characteristic of Southern Criminology is the highlighting of the everlasting criminogenic effects of colonialism. It challenges the suggestion made by Roger Matthews, in his paper “False starts, wrong turns and dead ends: Reflections of recent developments in Criminology,” that the greatest import of such a movement is the defiance of universalism of the theories of the Global North. It does so by examining the concepts of Southern Criminology, the risks of recognising the defiance of universalism as its main output and the potentialities of recognising its post-colonial characteristics for the advancement of theoretical criminology both in the Global South and the Global North.
A Comparative Study of War Crimes Prosecutions by Bosnia and Herzegovina and Serbia
Authors: Whitchurch Eleanor
Published: October 2021

This paper contrasts the diverging war crimes prosecution efforts of Serbia and of Bosnia and Herzegovina with the aim of determining which factors played a role in the radically different outcomes, and to what extent. It will measure three elements: the effect of international incentives, structural judicial challenges, and ethnic composition, in order to establish which element played the most prominent role in the strikingly lower effectiveness and efficiency of war crimes prosecutions by Serbia in comparison to Bosnia and Herzegovina. The findings suggest that ethnic composition has the strongest influence over the degree to which war crimes prosecutions are pursued, and that this can consequently determine the effectiveness of international incentives. These findings will allow for a better understanding of the success of past post-conflict criminal prosecutions. This enhanced understanding will in turn inform future war crimes prosecutions and help shape measures that could be taken to mitigate the destructive effects of the most prominent spoiling components.
Crime After Conflict
Authors: Provan Jack
Published: October 2021

Overwhelming statistical evidence shows a correlation between conflict and crime rates, both at a structural and individual level. This is assumed by many to mean that conflict is responsible for rises in crime. This article describes an alternative approach: that conflict is conducive to organised criminality, but does not necessarily cause it. By demonstrating examples from post-conflict societies, it is shown that the causal nexus of conflict and crime is actually security, development and governance. This effect is particularly pronounced where violent crime is concerned, but the inconsistent and often contextual nature of such crime renders any attempt to draw conclusions difficult. By framing peacebuilding efforts around conflict, and prioritising the neoliberal democratic model of the Global North as a cure to security and development shortcomings, crime is actually further enabled as the symptoms of criminality are not addressed. By returning the focus to security, development and governance, critical discussion may be able to cut through the noise and provide practical solutions to the crime epidemics characteristic of post-conflict environments.

Yemen has been a warzone for at least seven years now. The conflict is seemingly a civil war between the government and opposition forces. It also serves as a proxy war that determines the balance of power between Saudi Arabia and Iran in the region. The government in Yemen is aided by the Saudi-led Gulf Cooperation Countries (GCC), where Saudi Arabia (as well as other GCC members) purchases military technologies from the United States, Britain, France, and Germany. On the other hand, the opposition groups – the most prominent one being the Houthis – use Iranian technology in their fight. Considering the sophistication of military technology of the US and other Western countries vis-à-vis Iran, the duration of the war in Yemen stands out as a puzzle which this article attempts to explain using state-level analysis. After reviewing the situation since 2014, this article examines two existing arguments regarding the balance of power between Iran and Saudi-backed warring parties, namely, the hearts and minds argument and the military inadequacy arguments. Demonstrating the limitations of these, this article suggests that the Western powers contribute to the perpetuation of the war as they accrue a stream of revenue from arms production.

In order to determine the health risk derived from the presence of heavy metals on the residents of a town in the North of Mexico, 27 samples were taken from a tailings dam at a mine in "Cerro de Mercado". Among the various metals and metalloids found, antimony and chromium exceeded the permissible concentration values established by the Mexican legislation, so mining waste in that region was considered to be hazardous and harmful to health. The risk assessment was carried out using the Spatial Analysis and Decision Assistance software, selecting a recreational setting with a short time exposure, and a residential setting with long exposure, obtaining as a result, that the health of the residents nearby the mine will not be damaged by metals and metalloids exposure existing in the tailings.

En los últimos años es bien conocido la importancia de los factores cognitivos y afectivos en el desarrollo personal de los alumnos. Por ello, resulta necesario tener en cuenta las emociones que experimentan los alumnos de Secundaria en el aprendizaje de Física y Química, y su percepción de la capacidad para aprender contenidos. El objetivo de esta investigación es conocer las emociones experimentadas por los alumnos de secundaria hacia el aprendizaje de Física y Química, y la relación que existe entre las emociones y la percepción de su capacidad para aprender contenidos relacionados con la Materia, Energía y Electricidad, la Estructura y composición de la materia, Cinemática y Dinámica y, Trabajo y Energía. La muestra está constituida por 431 alumnos de ESO de distintos centros de Badajoz. Los resultados revelan que existe una relación positiva y significativa entre la frecuencia de emociones experimentadas por los alumnos y la percepción de su capacidad para aprender dichos contenidos. En cambio, existe una relación negativa y significativa entre las emociones negativas y la percepción de su capacidad para aprender contenidos científicos.
Aula invertida y trabajo colaborativo en Química

Published: October 2021

Implantamos las metodologías activas de aula invertida y trabajo colaborativo dirigido en la asignatura básica de Química del Grado de Ingeniería Agroambiental en la unidad temática dedicada a los equilibrios de precipitación. Participaron 101 estudiantes en los cursos 2018/2019 y 2019/2020. Los resultados muestran que la combinación de estos dos métodos condujo a resultados de aprendizaje significativamente más altos que la tradicional clase magistral con resolución de ejercicios, y revela una mayor motivación del alumnado. Una adecuada combinación de metodologías activas puede ayudar a que el alumnado sea partícipe de su evolución y logros, tanto en las competencias específicas como en las transversales. Sin embargo, el uso de estos métodos no tuvo incidencia en la tasa de abandono de la asignatura, por lo que es necesario realizar mejoras en su desarrollo como la creación de recursos audiovisuales propios o el aumento de la ratio profesor-alumno.
Aprendiendo reacciones químicas en tiempos de pandemia
Authors: Pozuelo Muñoz Jorge
Published: October 2021

Las actividades prácticas son una parte fundamental en la enseñanza de la química. Sin embargo,en un curso como es el último de instituto, no siempre se puede visitar el laboratorio habitualmente. En España, en los cursos 2019-2020 y 2020-21, con la suspensión de las clases presenciales y posterior recomendación de no uso del laboratorio en los institutos, la actividad práctica se ha reducido en su mayor parte. En este artículo se describe una actividad en la que el alumnado preparó y grabó en vídeo actividades experimentales simples sobre reacciones químicas en casa con materiales de uso común, para después visualizarlo y debatirlo entre todos, compartiendo así experiencias prácticas que enriquecieron el contexto formativo de los alumnos en tiempo de pandemia.

El artículo analiza el impacto en medios sociales de artículos peruanos del área temática de las Ciencias Sociales a través de la repercusión mediática en fuentes altmétricas y el tipo de acceso en el que se publican. Se analizan 1 186 artículos con filiación de instituciones peruanas recuperados de la base de datos Scopus (2011-2020), para lo cual se emplearon seis (6) indicadores altmétricos de Altmetric y citas de Dimensions. El método de análisis compara la repercusión altmétrica en relación con el tipo de acceso: abierto o restringido, en cinco áreas temáticas de las Ciencias Sociales: Artes y Humanidades, Negocios y Contabilidad, Ciencias de la Decisión, Economía y Finanzas, y Psicología. Los resultados muestran una alta correlación entre lecturas en Mendeley y citas de Dimensions (r = 0.797), y que existe una diferencia significativa por el tipo de acceso a la publicación en las menciones provenientes de Facebook (p = .000) y Twitter (p = .005). El estudio concluye que existe una mayor tendencia por parte de los autores peruanos que abarcan temas de Psicología en publicar sus artículos en acceso abierto, otorgándoles mayor visibilidad en Mendeley y Dimensions.
Lectura y conocimiento en Bibliotecología
Authors: Alfaro López Héctor Guillermo
Published: October 2021

Se busca comprender cómo se despliega cognoscitivamente la lectura a través del campo bibliotecológico, principalmente en la educación y la investigación, para lo cual se implementan los conceptos mediadores, intermediadores y traducción del sociólogo Bruno Latour. Los intermediadores consisten en las acciones que transportan contenidos sin que sufran cambios; así, la lectura concebida como intermediador ha predominado en el campo bibliotecológico y además está determinada por la objetividad. Los mediadores transforman la significación de sus contenidos al pasar por la traducción. La lectura como mediador conlleva la transformación de la información en conocimiento diferente o nuevo al ser traducido por mediación del planteamiento de problemas y preguntas al texto, lo cual propicia una lectura signada por la subjetividad y que puede constituirse en factor de transformación cognoscitiva del campo bibliotecológico.
Spatial and Seasonal Distribution of Heavy Metal Pollution in Tropical Lagoon off the Gulf Of Guinea
Authors: Ajani Ekaete Gloria
Published: October 2021

Abstract: The consistency of the aquatic environment at any point reflects basin lithology, anthropogenic input and climatic conditions. Spatial and seasonal distribution of heavy metal pollution in tropical Lagoon off the Gulf of Guinea was investigated between November, 2018 to October, 2019. Water samples were collected bi-monthly for heavy metal analysis and physicochemical parameters were measured in-situ every month. Results for physicochemical parameters were presumed to be ideal for marine life for both seasons as prescribed by the Federal Ministry of Environment. Salinity showed a significant negative correlation with temperature and a significant positive correlation with electrical conductivity (EC) during wet season. During the dry season, temperature showed a significant positive correlation with pH. As the temperature rises, molecular vibrations increase which results in the ability of water to ionize and form hydrogen ions and resulted into pH drop. The trend of heavy metal concentrations in the entire study area during the wet and dry season were in the order: Pb>Cu>Zn=Cr>Cd and Cu>Cr>Zn=Cd>Pb respectively. Nemerow’s Pollution Index (NPI) and Contamination Index (CI) were further used to evaluate pollution status of each metal in each sample station and contamination status of the entire sample stations respectively. The CI of the study area showed a decreasing order: Apapa > Iddo > Makoko > Ibeshe > Egbin and Ibeshe > Makoko > Iddo > Apapa > Egbin for wet and dry seasons respectively.

Probabilistic Assessment of Sandwiched Concrete Slabs in Deflection
Authors: Unamba K. U.
Published: October 2021

Abstract: This study presents a probabilistic evaluation of concrete sand-witched hollow core slabs in accordance with the design requirements of BS8110 (1985; 1997) and Eurocode 2 (2008). The First Order Reliability Method (FORM) was used in computing the probability of failure. For the deflection failure, the effect of varying the load ratio and the breadth of slab on the reliability analysis were carried out at the following values of concrete strengths ݂ܿu: 25N/mm2 , 30 N/mm2 , 40 N/mm2 , 50 N/mm2 . The results indicate that deflection characteristics of the slab are directly affected by the concrete strength, loadings, breadth of slab selected. Thus, the deflection of the slab increases with increases in loading, hollow core, breadth of slab and decrease in concrete strength. This shows that the safety index of reinforced sandwiched concrete slab in deflection generally decreases as the load ratio and breadth of slab increase for each combination of concrete strength.
