Years of Good Life: An illustration of a new well-being indicator using data for Thailand
Authors: Buathong Thananon , Dimitrova Anna , Vicerra Paolo Miguel M. , Chimmamee Montakarn
Published: August 2021

While Thailand has achieved high levels of economic growth in recent decades, poverty at the local level has been increasing. Indicators of human development at the national level often mask the differences in well-being across communities. When responding to the need for sustainable development research, the heterogeneity of a population should be emphasised to ensure that no one is left behind. The Years of Good Life (YoGL) is a well-being indicator that demonstrates the similarities and differences between subpopulations in a given sociocultural context over time. The data used in this analysis were collected from Chiang Rai and Kalasin, which are provinces located in regions of Thailand with high poverty rates. Our main results indicate that the remaining years of good life (free from physical and cognitive limitations, out of poverty and satisfied with life) at age 20 among the sample population were 26 years for women and 28 years for men. The results varied depending on the indicators applied in each dimension of YoGL. Our analysis of the YoGL constituents indicated that cognitive functioning was the dimension that decreased the years of good life the most in the main specification. This study demonstrates the applicability of the YoGL methodology in investigating the wellbeing of subpopulations.
Current aspects in the differential diagnosis of angioneurotic edema
Authors: Ilkova P. , Stoyneva Z. , Dimitrova N.
Published: August 2021

Angioedema is a disease characterized by various triggers and an increasing prevalence.
The great Greek physician Hippocrates (377-460 BC), considered one of the most outstanding figures in the history of medicine and "Father of the Western Medicine," already used the term oídēma to describe „swelling of organs“. It took many centuries later until the first description of angioedema as a distinct medical entity was minted by Quinсke in 1882.
The contemporary perception, defines аngioedema as a transient swelling of the skin or submucosal surface due to increased vascular permeability of small venules. The overlying skin may be normal or mildly erythematous.
Over time, many causes and factors that cause or trigger angioedema have been discussed.
There are two main types of angioedema without urticarial (histaminergic and nonhistaminergic) as the role of histamine in the pathogenesis of the disease is crucial. Angioedema is a frequent clinical condition that sometimes can be life-threatening. Different types of angioedema can be challenging to distinguish clinically. However, establishing a correct diagnosis is critical as different forms of angioedema require distinct treatment approaches.
Implementation of contemporary differential diagnostic approaches could be a prerequisite for an accurate diagnosis, which secures appropriate management strategies are possible.

The main aim of the present work is to describe a generalized electrodynamic model of the specific device operation, which provides detection and measurement of the geometric characteristics of the reinforcement cage in a concrete structure. The result of this study is the design of the device’s receiving-transmitting path that is optimal in a number of parameters, as well as a signal processing algorithm based on the operation of an artificial neural network trained on the generalized computer model output data. In addition to the main functionality of the device being developed, which consists in structureroscopy by the method of radar holography, useful target characteristics may be obtained during its operation: electrophysical parameters of concrete, structural defects, visualization of an object, etc. To solve this problem, on the basis of general radar principles, frequency-modulated continuous wave was chosen as the operating mode of the device. To create an electrodynamic model, the computer-aided design environment Pathwave EM Design (EMPro) 2021 was used. The developed generalized model may be optimized for a large number of parameters. In addition to the position and number of receiving antennas, the list of optimization variables may include parameters of the transmitting antenna (ray width, directivity, near-field distance), their number (i.e., the capacity of the MIMO system), power on the transmitting side, etc. The proposed scheme of the device is presented as the main result.
Dimensional Inconsistency Measures and Postulates in Spatio-Temporal Databases
Authors: Grant John , Martinez Maria Vanina , Molinaro Cristian , Parisi Francesco
Published: August 2021

The problem of managing spatio-temporal data arises in many applications, such as location-based services, environmental monitoring, geographic information systems, and many others. Often spatio-temporal data arising from such applications turn out to be inconsistent, i.e., representing an impossible situation in the real world. Though several inconsistency measures have been proposed to quantify in a principled way inconsistency in propositional knowledge bases, little effort has been done so far on inconsistency measures tailored for the spatio-temporal setting.

In this paper, we define and investigate new measures that are particularly suitable for dealing with inconsistent spatio-temporal information, because they explicitly take into account the spatial and temporal dimensions, as well as the dimension concerning the identifiers of the monitored objects. Specifically, we first define natural measures that look at individual dimensions (time, space, and objects), and then propose measures based on the notion of a repair. We then analyze their behavior w.r.t. common postulates defined for classical propositional knowledge bases, and find that the latter are not suitable for spatio-temporal databases, in that the proposed inconsistency measures do not often satisfy them. In light of this, we argue that also postulates should explicitly take into account the spatial, temporal, and object dimensions and thus define “dimension-aware” counterparts of common postulates, which are indeed often satisfied by the new inconsistency measures. Finally, we study the complexity of the proposed inconsistency measures.

Authors: Cui Y. , Liu S. , Liu Q.
Published: August 2021

To reduce the frequency of mining incidents and improve safety and production efficiency, it is important to develop technology for the autonomous positioning and navigation of mining equipment, without the assistance of satellite navigation signals. In this study we review the current technological environment for positioning and navigation underground and present several integrated navigation strategies. Existing underground positioning and navigation technology is described, and the performances of different methods based on this technology analysed and compared. The combination types and positioning effects of underground positioning and navigation strategies are discussed. Recent research directions for filtering methods and positioning estimation algorithms for underground positioning and navigation are reviewed. Finally, we summarize the future direction of underground positioning and navigation technology and related algorithms.
Mechanical properties and damage mode of cemented tailings backfill in an acidic environment
Authors: Huang Y. , Wang G. , Rao Y. , Liu W.
Published: August 2021

The properties and deterioration in strength of cemented tailings backfill (CTB )in the underground acidic environment under oxidizing conditions were studied. X-ray diffraction analysis and scanning electron microscopy of the surface of the CTB was carried out, and the sulphuric acid corrosion mechanism elucidated. The properties tested included compressive strength, elastic modulus, cohesion, internal friction angle, variation in the hydrogen ion concentration, and stress-strain relationship in different corrosion periods. The damage model of the CTB was established considering the effects of parameters such as corrosion time and strain on the damage evolution. It was found that the compressive strength, elastic modulus, cohesion (binder effect), and internal friction angle increased at first and then decreased with exposure time. In the long term, the peak stress decreased with corrosion time while the peak strain increased; elastic modulus, and deformation modulus also decreased. The damage caused by corrosion and by load were related by means of a mathematical model, which revealed the relationships between sulphuric attack, load, and damage to backfill in complex underground environments. During corrosion, the expansion of gypsum and ettringite caused microfractures in the CTB. With increasing corrosion time, micro-cracks developed and proliferated. The mechanism of corrosion damage was found to be the dissolution of hydrogen ions and a sulphate ion reaction that produces an expansive substance, resulting in deterioration of the strength of CTB.
Synthesis of Pt-based alloy nanostructures
Authors: Leteba G.M. , van Steen E.
Published: August 2021

Optimizing the catalytic performance of multimetallic nanoparticle (NP) catalysts demands a concrete understanding of their design, while preferentially deploying wet chemical synthesis procedures to precisely control surface structural properties. Here we report the influence of reductants such as hydrogen-rich tetrabutylammonium borohydride (TBAB) and carbon monoxide-rich molybdenum carbonyl (Mo(CO)6) on the shape and morphological evolution of Pt-based binary (PtNi and PtCo) and ternary (PtNiAu and PtCoAu) nanostructures derived from a homogeneous solution of amine-based surface active agents (surfactants) in a high boiling point solvent. We successfully synthesized nanostructures exhibiting well-defined and composition-controlled surfaces deploying a one-pot synthetic approach. The development of the surface properties was, however, observed to be alloy-specific. The resultant highly monodisperse alloy NP with narrow size distributions and facet-oriented surfaces are expected to display enhanced functionality as catalysts for utilization in specific chemical reactions.
Depositional environment - The original control on gold processing

Published: August 2021

Methods for treating and processing refractory gold ores are well established. However, what is less well understood is how the formation of the gold-bearing deposits affects gold processing and extraction. In order to evaluate the effect of ore genesis on gold extraction a number of South African gold deposits were studied. These included complex Pilgrim's Rest samples as well as refractory Fairview, Barbrook, and Consolidated Murchison samples. We found the refractory nature of gold ores is controlled by a limited number of well-understood mineralogical factors. Solid solution gold is linked to low temperature and pressure conditions in fine-grained sedimentary lithologies, while reactive pyrrhotite can form from hydrothermal fluids associated with mafic magmatic rocks. These formational controls can be used to identify and avoid complex deposits at a desktop study phase, or address and reduce complications further along the pipeline using early mineralogical studies.

Authors: Vásquez-Niño Andrés Felipe , Ochoa-Alzate José Rodolfo , Osorio-Amariles Daniel , Rodríguez-Quirós Henry Alberto
Published: August 2021

Introducción: con la aparición de nuevas tecnologías de manufactura han surgido nuevos materiales, como resinas de impresión 3D y discos CAD/CAM, todos empleados para fabricación de bases de dentadura. Actualmente no se cuenta con caracterizaciones mecánicas rigurosas para estos materiales, salvo lo expresado en fichas técnicas. Método: se fabricaron muestras para caracterización de propiedades mecánicas con un acrílico termopolimerizable convencional, un disco CAD/CAM de polimetilmetacrilato (PMMA) y dos resinas de impresión 3D. Se fallaron las probetas en una máquina universal de ensayos, según lo exigido por la norma ISO 20795-1 para el caso de la resistencia y módulo de flexión. La resistencia a la compresión también fue determinada. Se calculó el valor promedio de cada propiedad (n = 5). Se realizó un análisis de varianza de una vía y un análisis de Tukey para comparaciones múltiples. Resultados: los valores de resistencia a la flexión oscilaron entre 78.35±2.99 y 87.48±4.47MPa; el módulo de flexión estuvo en un rango entre 2125.43±57.05 y 2277.72±58.46MPa. La resistencia a la compresión fluctuó entre 85.03±2.14 y 119.15±2.87MPa. Los análisis estadísticos indicaron diferencias significativas para las resistencias a la flexión y compresión, pero no evidenciaron diferencias para el módulo de flexión. Conclusiones: todos los materiales evaluados cumplieron con la especificación mínima de propiedades mecánicas, dada por la ISO 20795-1. Desde el punto de vista mecánico, los nuevos materiales para las tecnologías digitales, discos CAD/CAM y resinas de impresión 3D, son aptos para su aplicación en manufactura de bases de dentadura.

Experiencias de familias en relación con su participación en la educación inclusiva de niños y niñas con discapacidad
Authors: Ortiz García Claudia Durley
Published: August 2021

En este artículo se presentan los resultados parciales de una investigación hermenéutica realizada con tres representantes de familias de la Institución Educativa Francisco Luis Hernández Betancur, ubicada en la ciudad de Medellín. La investigación indagó el sentido que las familias han otorgado a sus experiencias respecto a la participación en la educación inclusiva del niño o niña con discapacidad. Los hallazgos revelan cómo la experiencia de convivir con una persona con discapacidad puede convertirse en fuente de fortaleza para la familia, asunción de nuevos roles y modificación de las representaciones respecto a la discapacidad; aspectos que inciden en la participación familiar. La composición familiar tiene una implicación directa en las formas de participación, evidenciando una postura patriarcal en la que la mujer es quien debe asumir la responsabilidad, cuidado, crianza y educación del niño o niña con discapacidad y, en consecuencia, ella es quien participa de sus procesos de inclusión mientras el hombre toma un lugar marginal.
A Statistical Approach To Measure Uniformity Of Fuji Prescale Pressure Sensitive Film Samples

Published: August 2021

Fuji
prescale pressure sensitive films (FPPSF) are generally used in biomechanical
applications to measure the pressure distributions and the contact areas
between two contact surfaces as in coloured stains. FPPSFs are usually
calibrated based on the calibration methods using regression analysis to obtain
a specific calibration curve. However, researchers in literature achieve
different calibration curves based upon their tests and different processes.
The purpose of this study is to examine the calibration stains (data) obtained
experimentally using the FPPSF samples compressed between two smooth flat
surfaces to indicate contact pressures. The gray-level co-occurrence matrix
(GLCM) was used to evaluate the uniformity of the sample stains for
quantitative evaluation of uniform distribution of the sample stains. Moreover,
the generated calibration data is also compared and validated statistically
with the related calibration curves presented in the available literature. As a
result, the parameter of energy property of GLCM can be practicable to check
the image uniformity of samples in order for performing the accuracy of a
generated curve.

Published: August 2021

Background: Tibial plateau fractures are one of the most complex and disabling fractures of the knee. The tibial plateau is important in transmitting load through the knee. These fractures need a meticulous management protocol in order to minimize patient's disability in range of movement, stability and reducing the risk of documented complications. The aim of the present study is to study the outcome of tibial plateau fractures managed with a locked compression plate.

Methods: This study was conducted at a tertiary-care medical college and hospital, Aurangabad specializing in post-graduate training, where all patients who underwent surgical treatment between September 2018 and October 2020 were included. Patients were assessed using the knee society score (KSS). These evaluations were done at 1, 3, 6, 9 and 12 months.

Results: In our study we included 55 patients out of which we found union in 98% of patients with 83% of patients showing good flexion at knee joint (>110 degrees). 85% patients achieved union within 6 months. An excellent KSS grade was seen in 38.2% patients with another 43.6% showing good outcome. 4 patients showed infection and 1 showed non-union. A single case of malunion was seen in our study.

Conclusions: Locked compression plates in tibial plateau fractures has revolutionized the way these fractures are managed. Anatomic reduction is of utmost importance. Early physiotherapy which plays key role in preventing knee stiffness, use of bone grafts and good fixation are important for successful outcome.

Increasing disease incidence and prevalence has led to tremendous increase in the use of medications. The consumers are not able to use all the dispensed medications because of various reasons. The improper disposal of these unused medicines has led to environmental contamination to an alarming extent. The present study aims to assess the knowledge, attitude and practice of medical personnel about disposal of unused medicines.

The study was conducted on post graduate medical students, MBBS and nursing students of a tertiary care hospital of North India. It was cross sectional, descriptive study based on a structured questionnaire to assess the knowledge, attitude and practice about the disposition of left over medications. Descriptive statistical analysis of the results was done.

Stockpiling was reported by 100% of the students. The most common reason for stockpiling was excess purchase of medicines (41%). The most commonly procured medicine was NSAID (55.9%). The most common method of disposal was with household waste (69%). Majority of the respondents answered that take back programmes and government interference is the solution to this problem.

: Majority of the people are having unused medicines at home and most commonly they dispose it by throwing along with rubbish. Lack of knowledge regarding proper disposal is the main reason behind this. Initiatives should be taken to spread awareness regarding proper disposal methods of unused medicines.

El IGV como impuesto que incide en el tráfico comercial de bienes y servicios se circunscribe a una determinada territorialidad donde debe ocurrir el hecho imponible. En el Perú, la Ley del IGV establece que la Exportación de Servicios no está afecta a dicho impuesto, pero bajo determinadas condiciones donde resalta que el consumo del servicio por el sujeto no residente tiene que producirse íntegramente en el extranjero, a excepción de algunos supuestos señalados taxativamente en dicha Ley. Asimismo, conforme existe la Exportación de Servicios también podemos hablar coloquialmente de la Importación de Servicios o Utilización de Servicios prestados por sujetos no domiciliados, cuyo consumo o empleo se produce en territorio nacional independientemente del lugar de prestación.

Las modificaciones ambientales generan entornos de interfaz en los que la transmisión de Leptospira spp. puede verse afectada. Con el objetivo de identificar y analizar variables ecoambientales asociadas a potenciales reservorios de Leptospira spp. en la Reserva Ecológica Costanera Sur (RECS) (Buenos Aires, Argentina) y áreas urbanizadas contiguas, se realizó un muestreo por conveniencia en líneas transectas, estratificado y proporcionado. Fueron capturados 170 mamíferos de 11 especies y se analizó la presencia de Leptospira spp. por serología, cultivo y PCR. En áreas conservadas, se registraron mayormente Didelphis albiventris y Deltamys kempi, mientras que el Oligoryzomys flavescens también fue hallado en áreas degradadas, y la Rattus norvegicus solo fue encontrada en áreas degradadas. No se detectó Leptospira spp. en los mamíferos silvestres. Un perro sin tenedor responsable resultó positivo por ser0ología. Las condiciones ambientales de la RECS sugieren un ecosistema poco propicio para Rattus, evidenciando la importancia de la conservación de áreas naturales en entornos urbanos.

Fear in the fantastic narrative IT: a literary and cinematographic analysis
Authors: Araújo Naiara Sales , Costa José Antônio Moraes
Published: August 2021

The present study aims to analyze the manifestation of fear in the fantastic narrative It, in both literature and cinema. Supernatural themes are a constant in fictional prose, providing an increase in studies on the relationship between fear and fantastic narratives. As theoretical support, we build on the literary scholarship of Yi-Fu Tuan (2005), Stephen King (2013), David Roas (2014), Marcel Martin (2003) and Jacques Aumont (2013). As for methodology, a content analysis model is adopted in a bibliographic, exploratory and qualitative approach. It, A novel, as a fantastic narrative, destabilizes our sources of security by questioning the validity of the systems and beliefs created by and imposed upon on humanity. The results illustrate how the fantastic genre has been characterized as presenting us phenomena and situations that signal a transgression of our reality. This rupture with the real is, therefore, a fundamen- tal effect of fantastic narratives which have also been explored in cinematic narratives.

Breast pain, also known as mastalgia or mastodynia, is a common symptom that affects 70% of women during their lifetime [1]. It can impact quality of life and cause anxiety and distress for the patient [2]. Patients are most concerned about breast cancer as the cause of the pain [2]. Fortunately, the pain is rarely associated with breast cancer; it has been reported in only up to 7% of breast cancer patients in one population-based study.

Authors:   , Olano Ferreyra María del Rosario
Published: August 2021

El objetivo del estudio fue describir la construcción del sentido de pertenencia y la valoración de la trascendencia de la pertenencia en ex barristas de un club de fútbol de Lima (Perú). Para tal fin, se desarrolló un estudio cualitativo con diseño fenomenológico a través de la aplicación de entrevistas semi estructurada a siete ex barristas que asistían a los estadios en los años 90 y ejercieron un rol protagónico dentro de la barra. Los resultados muestran que los ex barristas han construido su identidad mediante la interacción con sus pares con los que comparten la misma afición por un equipo de fútbol y han establecido códigos, comportamientos y valores que los distinguen e identifiquen como grupo. Asimismo, identifican que lo más valioso de haber vivido esta experiencia de pertenencia, es haber aprendido a luchar por sus metas e ideales y el orgullo de haber forjado vínculos que mantienen hasta hoy. Se concluye que los ex barristas han desarrollado competencias como el liderazgo y la resiliencia; y su pertenencia ha tenido impactos significativos en su autoestima y forma de percibirse en el mundo que constituye su expresión de identidad, lo que confirma la identidad social positiva.
Less is More: The Simplification of Characters in Chinese Traditional Opera
Authors: Wu Jiede , Sun Yikang , Lin Rungtai
Published: August 2021

A simplification of Chinese traditional painting approach was proposed to study whether or not “Less is More” is still truly a design trend. A total of 225 volunteers from a website participated in the study. Through a questionnaire survey and analysis, this study explored the feasibility of “simplified” in comedy. The results show that the proposed approach of “simplification” can be applied to the drama character creation, but the simplification scale needs to be flexibly adjusted according to different topics. For viewers, there is not much recognition and liking for the works that are simplified to the extreme and present symbolization. In future research, the proposed “simplified” approach is needed to adjust and improve for practical use. It also needs more analysis of the differences in cognition of different participants according to the cognitive and communication theories of artistic creation.
Fundamentals of Physics-Informed Neural Networks Applied to Solve the Reynolds Boundary Value Problem
Authors: Almqvist Andreas
Published: August 2021

This paper presents a complete derivation and design of a physics-informed neural network (PINN) applicable to solve initial- and boundary value problems described by linear ordinary differential equations. The objective not to develop a numerical solution procedure which is more accurate and efficient than standard finite element or finite difference based methods, but to give a fully explicit mathematical description of a PINN and to present an application example in the context of hydrodynamic lubrication. It is, however, worth noticing that the PINN developed herein, contrary to FEM and FDM, is a meshless method and that training does not require big data which is typical in machine learning.

Although artificial insemination can mean a slow and progressive improvement of animal genetics, in buffalo-cow its practical application is difficult the results are incomparably lower then cattle. The purpose of this article is to develop a new methodology, a well-known technique to make AI biotechnology more applicable to the buffalo, in order to improve the conception rate. The protocol we follow is to stimulate hormonal ovarian activity, inducing the dominant follicle, causing ovulation and scheduling the moment of sexed artificial insemination deep in the uterine horn only ipsilateral to the ovary that will ovulate. The experiment was performed on 40 primiparous buffaloes-cows in two groups for AI separated by two bulls whit 2 Millions female sperm straws. The groups was compiled after a thorough gynecological examination, and subsequently the OvSynch therapeutic protocol was started. The results were 82,5% buffaloes (33/40) had dominant follicle (DF) and inseminated, on hot/cold seasons the distribution was 75%vs90%. The conception rate was 63,6% (21/33), on hot/cold seasons 60%vs66,6%, and after calving 92.5% (20/21) female cattle were obtained. Thus, by implementing UcFTAI protocol, we state that the goal of increasing the genetic potential of CIB by becomes achievable and can be extended to a larger scale. Our Improved Protocol (UcFTAI) aims to reduce waste and maximize OvSynch hormone therapy.
Pharmacological, Biochemical and Molecular Investigations in 6-OHDA Induced Parkinson’s Disease Rats on the Protection Benefits of Mangiferin in Behavioral, Inflammatory and Oxidative Biomarkers

Background: Persistent up regulation of NF-κB leads to chronic inflammation and subsequent microglial activation and takes neurons towards death by activating death receptor domains and the p53 pathway. Thus, inhibition of NF-κB may lead to more effective treatment for Parkinson’s disease. Therefore, we have used mangiferin, specific inhibitor of NF-κB in this study. Method: The study utilized male Wistar rats weighing 200-250 gm (n=8 in each group). Stereotactic surgery of rats was done to induce 6-OHDA lesioning in rats. On day 42, rats were subjected to behavioural studies to evaluate effect of mangiferin and their brains were taken out after euthanasia to perform biochemical and molecular studies. Results: Mangiferin significantly increases locomotor parameters in 6-OHDA lesioned rats. It also decreases activity of Cyclooxygenase enzyme which then leads to decrease concentration of inflammatory cytokines. Microglial inflammation was also substantially reduced by reducing MPO concentration. Oxidative stress burden was also reduced after treatment with mangiferin as indicated by increase in Total Antioxidant Capacity, SOD and Catalase and reduction in concentration of MDA. Treatment with mangiferin also reduces burden of oxidative stress by increasing the activity of NRF2/ARE pathway. Activity of Caspase 3 and 9 was also significantly reduced after treatment with mangiferin. Significant decrease in activity of both Cox1 and Cox 2 was also observed. Maximum improvement in all parameters was observed in rats treated with grouping of mangiferin 45mg.kg-1 and levodopa 10mg.kg-1. Treatment with levodopa alone has no significant effect on biochemical and molecular parameters though it significantly improves behavioural parameters. Conclusion and Implications: Results of this study suggest that mangiferin has protective effect in hemi-parkinsonian rats by inhibiting NF-κB. Current treatment of Parkinson’s disease does not target the underlying problem of the disease. Therefore, combination therapy of mangiferin and levodopa can be helpful in better management of Parkison’s.
The Amoebic Self Scale and GPA are related to the academic procrastination sensu lato
Authors: Bielinis Ernest , Bielinis Lidia
Published: August 2021

The Amoebic Self Theory is a concept of the social psychology, which postulates that humans have a psychological boundary. As the authors of the concept propose [1], the function of the boundary is to allow psychological separation of one from the others. In this study, we examined how sen-sitivity to violation of the boundary, measured by an amoebic self scale, is connected with differ-ent types of procrastination sensu lato, measured by seven procrastination subscales. Only two of the seven procrastination aspects, i.e. the preference for pressure and outcome satisfaction, were negatively and significantly related to the spatial-symbolic domain of the amoebic self scale. The other purpose of this research was to examine the connection between the students’ grade point average (GPA) and scores obtained in the procrastination subscales. Only the non-adaptive aspect of procrastination predicted significantly the GPA. That is an important detail, because pointing out the gap between one’s self-opinion and the real, non dependent of the opinion, academic achievement. All these findings were considered in the academic context and consequences of these results were discussed.
