Authors: AbuJarad Mohammed H , Khan Athar Ali , AbuJarad Eman S A
Published: September 2020

Modeling and analysis of survival rate has proved a fruitful aspect of statistical work in many fields of science. This paper aims at using a Bayesian approach to tting generalized DUS Exponential distribution (GDUSED). Kumar et al. (2015) proposed a renovation and called it DUS transformation. A Bayesian approach has been assumed to fit this model as a survival model. A real survival data set is used for illustration. Implementation is done using LaplaceApproximation and JAGS. Some graphical representations related to the probability density function and hazard function of the (GDUSED) are provided. LaplaceApproximation and JAGS codes have been provided to implement a censoring mechanism using both optimization and simulation tools.

The paper presents the results of researches of the modern ecological state South Bug and Aleksandrovskogo of storage pool the affected of the South Ukrainian power complex zone on hydrochemical indexes (main ions, mineralization of water, biogenic matters), which are the indicators of the ecological state of natural reservoirs. Research of the hydrochemical mode South Bug and Aleksandrovskogo of storage pool within the limits of the South Ukrainian power complex conducted during 2019.
An analysis of the got data is as compared to those, which took place more early, rotined that the water masses South Bug tested substantial changes (on the indexes of the chemical state). The conducted researches rotined that chemical composition of water S.Bug and Aleksandrovskogo of storage pool had been characterized sufficiently by the high values of mineralization of water, maintenance of main ions, especially sulfate and to general inflexibility.The features of spatio-temporal changeability of the main hydrochemical indicators of quality of water environment are set. Tendency of gradual increase of maintenance of main ions and of mineralization of water is traced on the longitudinal type of the river. The gradual diminishing from the winter to the summer and increase of mineralization of water and main ions an autumn is traced in a seasonal aspect.
It is known that the important index of the sanitary-hygenic state of natural reservoirs is content of biogenic matters. Worsening of the ecological state South Bug and Aleksandrovskogo of storage pool is set on maintenance biogenic matters. Modern researches rotined that and here took place changes are certain, namely: on an area in the district of South Ukrainian power complex zone something the concentrations of nitrate and ammoniacal forms of mineral nitrogen and phosphatic ions grew, that testifies to the decline of selfcleansing ability of the river and is the index of process second contaminations of the river.

Published: September 2020

El turismo industrial es una manifestación relativamente reciente del turismo cultural. Si bien la delimitación de su alcance temático y temporal es objeto de discusión entre la doctrina, paulatinamente se adopta una definición más integradora, que comprende el conjunto de manifestaciones materiales e inmateriales, asociadas a la cultura productiva capitalista del pasado y del presente. El objetivo de este texto es analizar el proceso de valoración social, cultural e institucional de los restos productivos y de la industria viva para pronosticar su impacto en la concepción de una oferta integradora de turismo industrial, representadora fidedigna de la cultura de la industria pasada y presente.
Turismo industrial: el caso alemán
Authors: Gallego Valiña Miguel Ángel
Published: September 2020

La revolución industrial de mediados del siglo XVIII fue clave para el desarrollo económico de Alemania. El turismo vinculado a la extensa tradición industrial y minera alemanas comenzó a obtener relevancia en la década de 1990 tras el cierre de la gran mayoría de las plantas productivas e impulsado por la inclusión en la lista de Patrimonio de la Humanidad de la UNESCO de tres de los estandartes de su patrimonio industrial, así como por la creación de rutas turísticas en torno a la cultura industrial del país, lo que convierte a Alemania en unmodelo de referencia para otros destinos europeos sobre cómo poner en valor el patrimonio industrial con fines turísticos y de ocio.

Ejercicio activo en la fase aguda posquirúrgica de una reconstrucción del ligamento cruzado anterior: revisión sistemática
Authors: Barrero-Santiago Laura , Santiago-Pescador Salvador , Santos-Lozano Alejandro , Justo-Cousiño Lorenzo Antonio
Published: September 2020

La rotura del ligamento cruzado anterior (LCA) es una de las lesiones más comunes, que constituyen casi el 50% del total de las lesiones ligamentosas de rodilla. A lo largo de los años se han creado diversas guías prácticas y protocolos para su tratamiento. Sin embargo, aunque varios estudios confirman los beneficios que aporta una rehabilitación precoz, no existe consenso sobre qué ejercicios activos se deberían realizar en fases tempranas. Por ello, en este estudio se ha llevado a cabo una revisión sistemática con el objetivo de analizar ensayos clínicos aleatorizados que han aplicado ejercicios en la rehabilitación precoz de una reconstrucción del LCA. Este estudio pretende determinar si el ejercicio activo en fase aguda posquirúrgica reporta beneficios y acorta el tiempo de tratamiento. Los resultados mostraron diferencias significativas en las diferentes variables (fuerza, dolor, rango de movimiento, laxitud ligamentaria y circunferencia del miembro inferior) en comparación con la valoración inicial de los respectivos protocolos. Por lo tanto, el ejercicio activo parece ser efectivo para favorecer la recuperación en fases tempranas posquirúrgicas, destacando el trabajo de potenciación de cuádriceps en fase precoz para la ganancia de rango de movimiento y disminución de la sintomatología. Actualmente no existen suficientes estudios realizados durante las dos primeras semanas posquirúrgicas para confirmar los beneficios del ejercicio activo.

Published: September 2020

The purpose of this study is to determine the effect of an acute local vibration exercise on the visual reaction time of a fencer’s upper body extremities. Twenty-six male fencers between the ages of 15 and 23 (mean age, 17.38 ± 2.13 years, height: 173.6±9.1 cm, body mass: 70.2 ±14.1 kg) volunteered for this study. The reaction time test was applied before and after the vibration exercise (applied for 30 seconds in 27 Hz with a 2-mm amplitude). After 25 min. standard warming up, fencers were informed about the test, and three repeated reaction tests were performed to provide familiarization. The fencers started the reaction test in the standard fencing guard position. According to five signals coming at two to five second intervals from the target monitor, the fencers made touché by bending (attacking). The reaction time test had five trials. The average reaction time values pre-vibration, and post-vibration were compared. The visual reaction time measured pre-vibration were significantly longer than those measured post-vibration (p<0.001). Acute local vibration exercise applied to fencers shortened the visual reaction time. Given the fact that vibration can improve RT, the use of vibration in training has the potential to provide an advantage to fencers.

Authors: Nielsen Rodríguez Adriana , Romance García Ramón , Parrado Merino Marta
Published: September 2020

Los métodos educativos de integración del movimiento son reconocidos como potenciadores de la actividad física, de las funciones ejecutivas y del aprendizaje. Sin embargo, el impacto de estas metodologías sobre la cognición y la actividad física en Educación Infantil ha sido poco estudiado. El objetivo de la investigación fue analizar el efecto de un programa educativo de integración del movimiento basado en el juego en esta etapa, evaluando sus efectos sobre los niveles de actividad física de los niños. Participaron 134 alumnos de 5 años de la provincia de Málaga. Se diseñó e implementó un programa de integración del movimiento basado en actividades de juego motor semi-dirigido que cambiaban cada quince minutos, en las cuales se trabajaron contenidos académicos. Se evaluó la cantidad e intensidad de actividad física mediante acelerometría (Actigraph GT3X). Durante su participación en el programa, los niños realizaron una media de 45,65 minutos de actividad física moderada-vigorosa. El porcentaje más alto corresponde a la actividad sedentaria y a la actividad moderada-vigorosa respectivamente, lo cual concuerda con estudios que afirman que la actividad de los niños pequeños consiste en ráfagas cortas de actividad moderada-vigorosa intercaladas con períodos de menor intensidad. Los datos muestran que el juego como método de integración del movimiento contribuye a alcanzar los niveles de actividad recomendados por las organizaciones internacionales. Nuestros resultados apoyan el uso del juego semi-dirigido como una herramienta especialmente útil para la mejora del proceso de enseñanza-aprendizaje en Educación Infantil y para el aumento de la actividad física del alumnado.

La práctica deportiva bien orientada puede fomentar al desarrollo valores tales como el respeto, el autocontrol, el esfuerzo, la autonomía y el liderazgo. En este sentido, el objetivo de este estudio fue doble: 1) realizar una revisión sistemática relativa a las investigaciones que examinaban los efectos de alguna intervención sobre el desarrollo del respeto en la formación de jóvenes deportistas; y 2) describir y analizar dichas intervenciones. Para tales fines, se llevó a cabo una revisión sistemática en la que se estudiaron y analizaron diferentes investigaciones sobre el respeto en el ámbito deportivo y de la Educación Física. Para realizar esta revisión sistemática se empleó la Declaración PRISMA. Los resultados más destacados hacen referencia a la aplicación exitosa del Modelo de Responsabilidad Personal y Social de Hellison (TPRS) y de la Educación Deportiva de Siedentop. De esta manera, tanto en el contexto escolar como en el de clubes deportivos, la utilización de intervenciones relacionadas con los Modelos mencionados es aconsejada cuando se pretende fomentar el respeto.
Editor's Note: The Sports Gambling (anti) Federalist Papers
Authors: Holden John
Published: September 2020

The foundation for this special issue was laid when the U.S. Supreme Court announced on May 14, 2018, that the Professional and Amateur Sports Protection Act (“PASPA”) violated the anti-commandeering principle contained within the Tenth Amendment. The decision in Murphy v. National Collegiate Athletic Association opened the door for states around the country to begin legalizing sports wagering for the first time in more than 25 years. The response to this newfound opportunity has been met with enthusiasm, with more than 15 states passing legislation to legalize sports gambling of various types within their borders in just over two years. The excitement over sports betting has not gone unnoticed by Congress, which, in September 2018, held a hearing titled “Post-PASPA: An Examination of Sports Betting in America.” The hearing sparked debate over what role the federal government should have in a new world where sports betting could be regulated across the country, as opposed to being confined largely to Nevada.
Moving Faster Than the Speed of Regulation: Can State-Authorized Sports Wagering Dodge a Game-Fixing Bullet Without the Help of the Feds?
Authors: Cabot Anthony , Miller Keith
Published: September 2020

The Professional and Amateur Sports Protection Act (PASPA), was a 1992 law that, as has been well-documented, effectively restricted sports betting to Nevada. PASPA accomplished this by dictating that states could not "sponsor, operate, advertise, promote, license, or authorize by law or compact," sports wagering. A separate provision forbade private parties from operating state-authorized sportsbooks. In 2018, the Supreme Court invalidated PASPA as a violation of the 10th Amendment to the US Constitution. The Court held that Congress did not have the constitutional authority to tell a state how to legislate and PASPA's provision that states could not authorize sports betting dictated to state legislatures what they were permitted to do and not do. The Court's ruling unleashed an explosion of pent-up energy for sports betting that had been building since PASPA became effective in 1993. Since that decision, several states have authorized sports betting in one of the most rapid expansions of a form of gambling in US history. Even more states are considering legislation that would permit sports betting, and the number of states legalizing and regulating sports betting will inevitably increase in 2020 and beyond. The controversy over sports betting has pivoted from whether states could legally offer sports betting, to whether they should legalize sports wagering, and if so, how they should go about regulating it.
We Can Handle It: Advocating in Support of State Legislation of Legal Sports Gambling post-Murphy v. NCAA
Authors: Spitz Daniel , Terry Ryan
Published: September 2020

Post-PASPA, more than twenty states have either implemented or successfully passed legislation allowing their citizens to gamble on sports. These legislative efforts have created an opportunity for states to capture some of the over $150 billion that Americans annually wager through illegal means. While Nevada has successfully regulated sports gambling for more than seventy years, the Supreme Court’s Murphy decision has spurred calls for uniform federal legislation. Central to this push for a federal framework are the leaders of the major sports leagues and their claim of concern for contest integrity. Our position is that this argument is tenuous at best. Rather, we believe this to be a convenient avenue for the major sports leagues to become involved in the regulatory process and secure additional revenue via integrity fees for providing data to federally mandated sources. Further, we argue that this framework of requiring states to use certified data sources that originate from the leagues themselves is not only economically damaging for potential sportsbook operators but could actually result in a greater chance of contest corruption rather than increased integrity. This article examines the contrasting views of the major North American professional and amateur sports leagues (NHL, NFL, NBA, MLB, and NCAA) with respect to the new, legalized sports gambling environment. We then look at the argument of maintaining contest integrity which is focal to proposed federal frameworks. Finally, we advocate for a state framework and demonstrate why states are in a better position to regulate sports gambling without federal interference, as state legislation already provides a mechanism by which income from wagers can be redistributed towards improving local infrastructure and funding social welfare programs; under proposed federal legislation, this revenue would divert elsewhere.

MiR-542-5p regulates the progression of diabetic retinopathy by targeting CARM1
Authors: Guo Ning , Nulahou Ayinu , Bu Qian , Liu Meng , Wang Yan , Zhao Yong , Yang Lei , Gao Yunxian
Published: September 2020

Diabetic retinopathy (DR), as the most frequent microvascular complication of diabetes mellitus (DM), causes vision loss and blindness in adults worldwide with increasing incidence. MicroRNAs (miRNAs) are involved in the regulation of DR. However, the role of miR-542-5p is still unknown. Here, we demonstrate that miR-542-5p is down-regulated in patients with DR and in high-glucose (HG)-treated retinal pigment epithelial cells. Moreover, miR-542-5p overexpression inhibits apoptosis in retinal pigment epithelial cells exposed to HG. The interaction between miR-542-5p and co-activator-associated arginine methyltransferase 1 (CARM1) is confirmed. MiR-542-5p mimics decrease the CARM1 level and miR-542-5p inhibitor increases the CARM1 level. Additionally, CARM1 overexpression promotes the miR-542-5p-mediated apoptosis in HG-treated retinal pigment epithelial cells. In summary, the data suggest that miR-542-5p may suppress apoptosis in retinal pigment epithelial cells via targeting CARM1, which provides a new therapeutic target for the treatment of patients with DR.
Productivity Improvement of Smallholder Coffee Plantation to Prevent the Expansion of the Plantation into Protected Forest
Authors: Hafif Bariot , Herman Maman , Syafaruddin - , Nazir Novizar
Published: September 2020

Farmers expanded the smallholder plantation to the protected tropical rainforest area due to declining of coffee productivity by the old age of coffee trees and degraded soils in West Lampung, Sumatra Island of Indonesia. The research aimed to study the performance of rehabilitated Robusta coffee trees and citronella grass (Andropogon nardus L.) as a conservation crop to improve the smallholder coffee plantation productivity. The old Robusta coffee trees (more than 25 years old) were rehabilitated by side grafting. Scions for the grafting were superior clones such as Sumber Asin (SA) 237, Besoekish Proefstation (BP) 436, and 534. In the experiment, two scions were grafted to each of 600 local Robusta coffee trees. To know the effect of grafting, the coffee trees were observed using stratified random sampling with equal sample allocation. The strata were varying positions of land on the hill, i.e., peak, ridge, and bottom, and the other were the three clones. The citronella was planted along the contour line among the coffee trees, with a vertical interval (VI) was 1.25 m. On average, the two grafted branches of coffee trees could produce green beans 453 g. It was higher than the average yield of the farmers’ coffee trees, i.e., 387 g tree-1. The SA 237, however, was vulnerable to the attack of berry borer (Hypothenemus hampei). Besides, to control erosion, the citronella grass under 40 to 60% covered by coffee trees canopy, produced fresh leaves 10-ton ha-1year-1 or essential oil as much as 87 L (essential oil content of leaves 0.87%), approximately. That was equivalent to $1,115 in a year. The citronella also improved the soil chemical properties, especially organic-C, P2O5, Ca2+, Mg2+, and Al3+.
Investigating the Adoption of Digital Payment System through an Extended Technology Acceptance Model: an Insight from the Indonesian Small and Medium Enterprises
Authors: Najib Mukhamad , Fahma Farah
Published: September 2020

Digitalization in the payment system has been promoted by the Indonesian government since the government is targeting to become the largest digital economy in Southeast Asia. However, not all companies can adopt digital payments quickly. Small and Medium Enterprises (SMEs) have many obstacles to adopt innovative technologies, mainly due to a lack of knowledge and resources. On the other hand, many consumers are getting used to digital payments and demanding SMEs to facilitate their transaction processes with digital payment systems. Therefore, the primary purpose of this study is to analyze factors affecting the digital payment system adoption in SMEs, particularly small and medium-sized restaurants. It used an extended Technology Acceptance Model (TAM) as a theoretical framework. Thus, 120 data were gathered using self-administered questionnaires from owners or managers of small and medium-sized restaurants in Bogor, Indonesia. Structural Equation Modeling with Partial Least Square (SEM-PLS) was employed to assess the hypotheses that were developed. The findings suggested that the intention to use digital payment was determined by the perceived ease of usage, perceived usefulness, attitude towards digital payment, and trust. This research approved that the applicability of TAM with the inclusion of additional variables in the model and the adoption of the digital payment system in small and medium-sized restaurants in developing countries like Indonesia. It offers valuable information for policymakers and financial institutions such as banks in understanding the critical variables influencing large scale implementation of the digital payment system in Indonesia.
Estimation the Natural Frequencies of a Cracked Shaft Based on Finite Element Modeling and Artificial Neural Network
Authors: Flaieh Enass H. , Hamdoon Farouk Omar , Jaber Alaa Abdulhady
Published: September 2020

The early detection of faults in rotating systems considers an integral approach that has received considerable attention from the industrial sector, as it contributes to preventing catastrophic failures in machines. In this research, the natural frequencies of a shaft, when it is healthy and when cracks with different depths are introduced, have been calculated. The deviation of the computed natural frequencies from the healthy ones is counted as a sign of the presence of an abnormality in the system. For this intention, the finite element analysis (FEA) method based on ANSYS software has been utilized to obtain the first five natural frequencies of the shaft when there is a crack of different severity at different positions. The results of the FEA are used for designing an artificial neural network (ANN) model that can be easily used to predict the first five natural frequencies of the shaft based on just the crack’s position and depth. Finally, the predicted natural frequencies by the deigned ANN have been compared to their peers that were computed using the FEA method. The absolute error percentage has then been calculated and used to get an indication of how close the result of both techniques is. The recorded highest error percentage was 0.67%, which is quite small and referring to that the designed ANN can accurately predict the natural frequencies of rotating systems.
Reference Class-Based Improvement of Object Detection Accuracy
Authors: Park Raegeun , Jo Jaechoon
Published: September 2020

To date, the Frames Per Second (FPS) and accuracy of object detection based on deep learning have made rapid progress. However, the accuracy is limited by issues such as false positive (FP) cases. FP cases can trigger malfunctions in applications requiring high accuracy, such as in autonomous vehicles, where it is essential to ensure driver safety when malfunctions occur. To reduce the occurrences of FP cases, we conducted an experiment to derive the association by separately detecting a highly relevant element called a reference class, in addition to the target class to be detected. To measure the association, we obtained the integrated association by first finding the associations between the bounding boxes of the target and reference classes. Then we generated a reference class-based model by applying the integrated association to a trained model. The reference class-based model achieved approximately 15% higher accuracy than the trained model at iteration 1,000. Besides, the proposed model reduced the FP cases to approximately half of the 18.964% in the conventional method; the FP reduction through an increase in iteration was only 11.008%. The reference class can be applied in various fields, such as security and autonomous vehicle technology. It can be used to reduce the FP cases and improve the accuracy performance limits in object detection. Furthermore, it is possible to reduce the cost of reinforcing the training dataset and using high-performance hardware, and the time cost of increasing training numbers.

Corpos utópicos e heterotópicos
Authors: Ferraro José Luís Schifino
Published: September 2020

Este ensaio aborda a problemática do corpo na educação em ciências. Para tanto, toma como exemplo o corpo utópico utilizado na ciência, colocando-o em uma perspectiva crítica a partir do seu não reconhecimento como modelo corporal. Como contraponto, trabalha com a ideia de corpo heterotópico, como corpo real, singular, que se produz e se traduz como prática de resistência. A partir deste conceito evidencia-se o potencial da educação em ciências para a estetização da ciência, recolocando a discussão do reconhecimento e da autodeterminação do outro como pauta para uma agenda formativa humanística, comprometida com uma ético-estética das alteridades na ciência.

Published: September 2020

This study aims to evaluate the use of silicon base (NS) and functionalized (NF) nanoparticles as emerging preventive surface treatment (ST) in reinforced concrete specimens. The specimens were fabricated with a water/cement (w/c) of 0.65 and subjected to a previous aging period through exposure to CO2. Subsequently, two different variants of the treatment were applied by spraying (using a 0.1% dispersion of nanoparticles in water) and then re-applied to carbonation. The carbonation depth and contact angle results indicate that there is an influence between the degree of aging and the efficiency of each treatment.
Automatic Characterization of Pelvic and Sacral Measures from 200 Subjects
Authors: Veilleux Nathan J. , Kalore Niraj V. , Vossen Josephina A. , Wayne Jennifer S.
Published: September 2020

Background:

An understanding of pelvic and acetabular morphology and orientation is required for accurate surgical reconstruction of the hip and spine, as well for component placement in a total hip arthroplasty. Our objectives were to develop an automated system for measuring pelvic and sacral orientations utilizing computed tomographic (CT) scans and to characterize these measures across 200 asymptomatic subjects.

Methods:

An automated feature recognition algorithm was created to identify acetabular and pelvic orientation across 200 scans generated for non-musculoskeletal conditions. Three-dimensional models were generated from CT data to serve as inputs to the algorithm. Acetabular orientation was defined by comparing a plane fit to the acetabular rim with the anterior pelvic plane. Pelvic inclination, pelvic tilt, and sacral slope were defined as the angles between landmarks identified across the pelvis: pubic tubercles, acetabular center, left and right anterior superior iliac spines, and sacral plate.

Results:

The mean sacral slope was 36.49°, the mean pelvic tilt was 15.60°, and the mean pelvic incidence was 52.05°. The mean sacropubic angle was 32.48° and the mean pelvic-Lewinnek angle was 8.93°. Significant differences between male and female subjects were observed in the sacral slope (mean difference, 4.72°; p < 0.05), pelvic tilt α (mean difference, 4.17°; p < 0.05), pelvic tilt γ (mean difference, 3.06°; p < 0.05), and the pelvic-Lewinnek angle (mean difference, 1.76°; p < 0.05). The comparison of acetabular orientation measures with those in a prior study of the same cohort yielded intraclass correlation coefficients (ICCs) all above 0.97. The validation of sacral orientation via manual measurement also yielded ICC values all at or above 0.97.

Conclusions:

Our algorithm showed a high degree of consistency in acetabular orientation measures with respect to a prior study of the same cohort. The measures of pelvic orientation were found to be accurate and reliable when compared with manual measurements of the same data set. All measurements of pelvic orientation were consistent with the means reported in the literature.

Clinical Relevance:

An accurate and reproducible, automated technique for determining pelvic and acetabular orientation provides a way to characterize these measures as an aid in clinical diagnosis and preoperative planning.

Introdução: a Odontologia Legal é considerada um método primário de identificação humana. Consiste na comparação de informações da arcada dentária de um indivíduo em dois momentos distintos, geralmente ante e post-mortem. Por essa razão, necessita-se que as informações ante-mortem estejam bem expostas, atualizadas e conservadas na documentação odontológica. Objetivo: a partir dos laudos cadavéricos realizados pela equipe de odontolegistas em corpos não identificados, avaliar, de acordo com as normas éticas e legais odontológicas, as documentações enviadas ao Instituto Médico-Legal (IML) de São Luís – Maranhão, com vistas à identificação desses cadáveres, assim como a sua interferência no confronto entre os dados ante e post-mortem. Material e Métodos: análise dos laudos cadavéricos elaborados pelo IML-MA, bem como das documentações recebidas para posterior confronto de supostas vítimas, no período de 2014 a 2019. Resultados: os laudos revelam que em 76,3% (374) dos cadáveres constavam procedimentos odontológicos realizados em vida, porém apenas 6,4% (24) desses casos apresentavam seus respectivos registros. Discussão: é dever do cirurgião-dentista produzir e conservar uma documentação odontológica satisfatória para cada paciente. Além de servir como defesa do profissional em eventuais processos judiciais, é essencial para a identificação humana através da Odontologia Legal. Sua ausência resulta em maior custo e tempo para uma resposta aos familiares da vítima e ao Estado. Conclusão: o número de documentações clínicas encaminhadas ao IML é aquém do esperado (27), porém a adequada qualidade dessas documentações permitiu 72,4% (21) identificações positivas das vítimas, evidenciando a importância da Odontologia Legal na identificação humana.

O Código de Ética Odontológica (CEO) brasileiro, instituído em 1957, regulamentou o exercício da Odontologia e da ética profissional. Desde então, foram instituídas mais sete versões do CEO que acompanharam as necessidades da profissão e evoluíram com a sociedade brasileira. No entanto, em tempos de quebra de paradigmas éticos é necessário resgatar a origem da filosofia comportamental que rege a profissão. Frente a isso, este trabalho teve como objetivo analisar versões antigas do CEO, comparando-as com a edição atual, avaliando os artigos já existentes, alterações e complementações. A comparação de suas versões permitiu melhor percepção das mudanças da regulamentação da profissão odontológica ao longo das décadas e seus motivos. A realização de uma avaliação de cada artigo buscou as alterações de texto, inclusões e exclusões em cada versão do CEO, dados que foram analisados qualitativamente. Perceberam-se grandes modificações referentes à publicidade e propaganda, honorários profissionais e penalidades e suas aplicações ao longo do tempo, o que leva à reflexão de que o relacionamento com o paciente, a liberdade do profissional e as suas obrigações no âmbito da Odontologia são questões que estão em constante evolução e que necessitam de atualizações devido à complexidade da sua temática.

A identificação humana post mortem é uma área de estudo e pesquisa de extensa atuação da Odontologia Legal. Nessa área do conhecimento, a forma mais utilizada é a da comparação dos registros ante mortem (AM) com os achados post mortem (PM). Em casos de cadáveres carbonizados, geralmente os elementos dentários são capazes de resistir à ação térmica. Dessa forma, os exames de imagens que integram os prontuários odontológicos, quando em boa qualidade, possibilitam sua comparação com os mesmos exames realizados no cadáver. O propósito desse artigo foi o de relatar um caso em que a comparação de tomografias computadorizadas AM e PM permitiu a identificação positiva de um cadáver carbonizado. A comparação das imagens tomográficas AM, utilizadas para um planejamento reabilitador com implantes, com as imagens PM, realizadas no Instituto Médico Legal da Polícia Civil do Distrito Federal, permitiu, de forma rápida, eficaz e econômica, a identificação positiva do cadáver devido à quantidade e à qualidade dos pontos semelhantes encontrados nas imagens, associados à ausência de divergências inexplicáveis
Cr2O3:TiO2 Nanostructure Thin Film Prepared by Pulsed Laser Deposition Technique as NO2 Gas Sensor
Authors: Kareem et al. Saadoon M.
Published: September 2020

Pulsed laser deposition (PLD) technique was applied to prepared Chromium oxide (Cr2O3) nanostructure doped with Titanium oxide (TiO2) thin films at different concentration ratios 3,5,7 and 9 wt % of TiO2. The effect of TiO2 dopant on the average size of crystallite of the synthesized nanostructures was examined by X-ray diffraction. The morphological properties were discussed using atomic force microscopy(AFM). Observed optical band gap value ranged from 2.68 eV to 2.55 eV by ultraviolet visible(UV-Vis.) absorption spectroscopy with longer wave length shifted  in comparison with that of the bulk Cr2O3 ~3eV. This indicated that the synthesized samples are attributed to the enhancement of the quantum conﬁnement effect. Gas response sensitivity, and recovery times of the sensor in the presence of NO2 gas were studied and discussed. In this work it is found that, the sensitivity increases when doping ratio increases from 3wt% to 5wt% of TiO2  and return to decrease over that. The optimum concentrations ratio for NO2 gas sensitivity is 5wt% of TiO2  and sensitivity is 168.75% at 200oC.

The ability of beans (Phaseolus vulgaris L.) to uptake three pharmaceuticals (diclofenac, mefenamic acid and metronidazole) from two types of soil (clay and sandy soil) was investigated in this study to explore the human exposure to these pharmaceuticals via the consumption of beans. A pot experiment was conducted with beans plants which were grown in two types of soil for six weeks under controlled conditions. During the experiment period, the soil pore water was collected weekly and the concentrations of the test compounds in soil pore water as well as in plant organs (roots, stems and leaves) were weekly determined. The results showed that the studied pharmaceuticals were detected in all plant tissues; their concentrations in plant roots were higher than plant stems and leaves. The extent level and accumulation of the studied pharmaceuticals in sandy soil was higher than the clay soil. The concentration of diclofenac in plant tissues was higher than both of mefenamic acid and metronidazole, indicating that diclofenac is more available to plant. The content of dissolved pharmaceuticals in soil pore water decreased gradually over time during the experimental period confirming the ability of beans to uptake these pharmaceuticals from soil. The results suggest the possibility of studying pharmaceuticals to be accumulated in beans tissues despite their low concentrations in the studied soils.

This paper presents a sight about the chemical structure deformation of poly (ethylene-co-vinyl acetate) (EVA) samples according to the change ratio of rate constant values. Spectroscopy kinetics fluorescence curves are fitted for two characteristic wavelength domains of fluorescent intensities. The short wavelengths (320-400 nm) domain show spectra overlapping, while at long wavelengths (400-800 nm) domain spectra are arranged in regular for each specific accelerated aging time. The ratio of kinetics rate constant at long wavelengths to kinetics rate constant of short wavelengths is the criterion of the degree chemical structure deformation. Molar extrinsic coefficient relies on the chemical structure change. Through absorbance measurement, EVA samples have been classified into two groups. Presence of Cyasorb additive is the key point of the ranking. The effect of three different accelerated aging of dry (115 oC), damp (85% moisture, 85 oC), and irradiated (UV, 65 oC) aging have been considered for two samples of each group over different aging time. Spectroscopy of absorbance and fluorescent for aged samples have been discussed. In general, Cyasorb adding causes higher chemical structure deformation for the EVA sample. The most effective factor is the damp aging and the less one is the UV irradiation aging, while the biggest chemical structure change of Cyasorb-free sample is produced by damp aging and the less by dry heat.
Geomagnetic Kp Index and Planetary Magnetosphere Size Relationship: for Mercury and Jupiter During two Types of Geomagnetic Conditions

Kp index correlates with the many magnetosphere properties, which are used to measure the level of magnetic activity. In the solar system, the two different planets, Mercury with weak magnetic field and Jupiter with strong magnetic field, are selected for this study to calculate the planet's magnetosphere radius (RMP) which represents the size of magnetosphere compared with solar activity through Kp index,  through two types of geomagnetic conditions; quiet and strong for the period (2016-2018). From the results, we found that there are reversible relations between them during strong geomagnetic storms, while there are direct relations during quiet geomagnetic conditions. Also it is found that there is a reduction in the size of magnetosphere during the strong geomagnetic storms as compared to the magnetosphere size during geomagnetic quiet conditions for the two planets: Mercury and Jupiter. We can conclude from these results that the relation between storm type and magnetosphere size is independent of the strength of planetary surface magnetic field and their distance from the Sun.
