Authors: Z. Fazly-Ann , M.Y. Nor-Hafizah , Rukayadi Yaya
Published: September 2019

The berries of Piper cubeba L. or commonly recognized as tailed pepper are traditionally
used as flavoring ingredients in various types of food. It has been reported with abundant
of phytochemical compounds that contribute to its nutritional and medicinal properties.
The antimicrobial effect of the spice including antifungal activity was believed to reduce
the potential of fungal spoilage thus minimizing food losses and wastage. This study was
aimed to determine the antifungal activity of P. cubeba L. extract against isolated spoilage
fungi namely Geotricum candidum (TMa 001), Penicillium citrinum (GRd 001) and
Trametes hirsuta (LMd 001) by in vitro and in vivo techniques. Disc diffusion assay,
minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC)
test of the methanolic extract were performed on the selected fungi. The largest inhibition
zone, fungistatic and fungicidal effects were detected in T. hirsuta with 18.30±3.00 mm,
0.039 mg/mL and 0.078 mg/mL, respectively. The inhibition of conidial germination
assay was performed at 0 × MIC, 0.5 × MIC, 1 × MIC, 2 × MIC, and 4 × MIC, and the
result showed G. candidum were completely inhibited at 4 × MIC. The ideal concentration
of P. cubeba L. extract on different selected food commodities were 0.50% against G.
candidium in tomato, 0.50% to 5.00% against P. citrinum in grapes, and 5.00% against T.
hirsuta in lemon. The findings implied that P. cubeba L. extract can be listed as one of the
natural antifungal agents in food. The availability of various types of natural antifungal
agents will help in reducing the usage of chemical fungicide, which may lead to adverse
and deteriorating health effects in the events of prolong consumption.

Published: September 2019

This paper explores the ability of artificial intelligence (AI) to detect or interpret emotions from information provided in the form of text. The study utilizes surveys (profiles) of 10 participants receiving palliative care. The profiles are analyzed manually by human experts and separately by IntenCheck, an AI system, to identify emotions displayed by each profile. The findings of each entity is then compared. This research is preliminary in nature and is the groundwork for forthcoming use of this technology. In the future, this work will incorporate a predictive model once a reliable form of emotion-identifying AI is achieved. The predictive model will assess overall positive or negative emotion of text, and subsequently, compare the success of treatment and livelihood of patients. After comparing the overall emotion with sustainability of numerous people, the AI will expectantly be able to analyze and predict the success of treatment and the likelihood of achieving preferred outcomes for patients based on their personal profiles.
Performance assessment of IGS Combined/JPL individual rapid and ultra-rapid products: consideration of precise point positioning technique
Authors: OGUTCU Sermet
Published: September 2019

Satellite orbit and clock products are the key elements for precise point positioning (PPP). Contrary to the relative technique, errors in satellite orbit and clock directly lump to the station coordinates for PPP technique. Currently final, rapid and ultra-rapid (observed-half and predicted-half) satellite products have been made freely available over the internet mainly for Global Positioning Service (GPS) satellites. Final and rapid products are used for post-processing applications. For real-time and near real-time applications, ultra-rapid products with predicted and observed parts can be used. There are several analysis centers that provide the satellite orbit and clock products. In this paper, accuracy and precision of GPS rapid and ultra-rapid satellite orbit and clock products from two services, International Global Navigation Satellite Service (IGS) and Jet Propulsion Laboratory (JPL), were investigated in the position domain of PPP technique while the final products of these services were taken as the true value. Ten IGS stations around the world were chosen for PPP processes. 24-12-8-4-2 hours of non-overlapping arc-lengths of GPS observations in 31 consecutive days (DOY 1-31 of 2018) were processed for each station. The results confirm that the shorter the arc-lengths, the larger the relative error of rapid and ultra-rapid products due to the similar Gaussian distribution pattern of the orbit errors with respect to the final products. In terms of consistency between the products, Root-Mean-Square-Errors (RMSE) of final-rapid differences of IGS and JPL are at the millimeter level. Millimeter level accuracy can be obtained using rapid and ultra-rapid products for JPL whereas only rapid products of IGS maintain millimeter accuracy with respect to the final products.

A glândula parótida é uma glândula salivar maior, que abriga um feixe vasculonervoso e está situada no espaço parotídeo, um arcabouço ósseo e muscular. Ela pode ser avaliada por diferentes exames de imagem, principalmente pela ultrassonografia (USG), a tomografia computadorizada (TC) e a ressonância magnética (RM). Faz-se necessário o conhecimento de sua condição de normalidade para compará-la à de afecção, pois procedimentos cirúrgicos são frequentemente requeridos como meio de tratamento. A maioria dos pesquisadores e profissionais que manejam essa glândula referem a necessidade de estudos mais aprofundados, visto que o conhecimento acerca do assunto é limitado e suas patologias e manejo são pouco explorados e contraditórios na literatura.
Da necessidade e oportunidade da exodontia: relato de caso de incisivo superior retido
Authors: Bispo Luciano Bonatelli
Published: September 2019

A evolução dos materiais e técnicas na Odontologia Contemporânea aperfeiçoou as possibilidades terapêuticas assim como os meios de diagnóstico por imagem. Utilizar meios complementares aos exames clínicos colabora para uma maior previsibilidade de tratamento, com menor morbidade para o paciente e maior segurança na localização anatômica de estruturas nobres. A segurança cirúrgica está centrada no binômio mínima invasão dos tecidos e confiança interventiva, com evidentes benefícios durante a anestesia/diérese, a hemostasia, bem como a síntese. Planejar adequadamente possibilita prever riscos e ponderar eventuais sequelas que possam surgir durante e após o ato operatório. Mesmo que a desejável correção ortodôntica e a imediata instalação de fixações não sejam possíveis, aguardar a oportunidade ideal de reabilitação e a necessidade de intervenções posteriores requerem uma curva de aprendizagem que denota paciência e meticulosidade. Variáveis como dentes retidos, lesões intraósseas, falta de espaço na arcada dentária, proximidade com vasos sanguíneos e nervos, entre outras; constituem empecilhos comumente encontrados na clínica diária. O objetivo deste trabalho foi ilustrar um caso clínico cuja remoção de um incisivo superior retido melhorou a condição oclusal do paciente, para que pudesse ser submetido, posteriormente, a uma correção ortodôntica para ganho de espaço e aposição de fixação osseointegrada em área estética.

Authors: BIBIRE LUMINITA , BARSAN NARCIS
Published: September 2019

Injection is an economical process characterised through an increased productivity that leads, in the majority of cases, to finite pieces. The process of injection includes two distinctive phases, firstly, when the melting occurs, followed by the homogenisation and the creation of pressure; the process takes place in the plasticizing unity; coming next being the second phase that consists in the forming of the producs, in the cavity of the matrix. Regarding the main factors, the purpose of this paper was insuring a thermic regime as uniform as possible in order to obtain an appropriate plastifying process. To do this, with the help of a thermovision camera type Fluke Ti20, the thermic regime has been studied in the area of the plastifying cylinder, following the balancing of the heating resistances.

A NUMERICAL STUDY REGARDING THE INFLUENCE OF THE LONGITUDINAL EXTENT OF A T-SHAPED CRACK ON THE EIGENFREQUENCY DECREASE OF CANTILEVER BEAMS
Authors: TUFISI CRISTIAN , GILLICH GILBERT-RAINER
Published: September 2019

The paper analyzes the effects of T-shaped cracks in beams regarding the manner in which the frequencies of the bending modes change. We determined the eigenfrequencies of the damaged beam involving the finite element method for five lengths of the branched crack’s longitudinal components and numerous crack locations. This permitted plotting the frequency shifts curves and calculating the relative frequency shifts. Afterward, we extracted the damage patterns for all crack types and one crack position. It was found that the patterns are quite similar, just differing by their amplitudes, thus by normalization the damage severity effect can be suppressed.

VIBRATIONAL CASE STUDY FOR THE MOLD OSCILLATOR WITH HYDRAULIC SERVO SYSTEM
Authors: YONGHUI PARK , CHANGWOO LEE , DONGWOOK KIM
Published: September 2019

We have conducted sensitivity analysis to investigate the two-hydraulic-servo system for the mold oscillator. By modelling mathematical models for operating fluid flow to control a hydraulic cylinder, we changed design parameters and environment conditions including friction, additional spring stiffness and fluid leakage. From the one-hydraulic servo system to the two-hydraulic cylinder, modal analysis was conducted to figure out dynamic characteristics of the real system. Especially, we categorized important natural mode shape. When the system was excited into the natural frequency, the 1st mechanical natural frequency could cause a pressure gain by reducing internal pressure of a hydraulic cylinder, but other natural frequencies were critically dangerous by generating imbalance, over-vibration and distortion. By comparing the results to the experimental data, we could find a dramatic pressure drop near 3 Hz oscillation when the system has the 1st mechanical natural frequency 2.499 Hz. Also, the system has the imbalance near 6 Hz oscillation when the system has 2nd mechanical natural frequency 5.446 Hz. Based on these fact, we have suggested some tips to oscillate a mold efficiently and safely.

Peligro de incendios forestales asociado a factores climáticos en Ecuador
Authors: Pazmiño Daniel
Published: September 2019

Los incendios forestales producen severos impactos en Ecuador. El Ministerio del Ambiente de Ecuador señala que los incendios forestales destruyeron 21,570 hectáreas en este país en 2012. Esta temporada de incendios forestales le costó al Distrito Metropolitano de Quito, la capital de Ecuador,  aproximadamente 50 millones de dólares. A pesar de las pérdidas que producen los incendios forestales, se desconoce como el clima influye en la ocurrencia de los mismos en Ecuador. Este estudio es la primera investigación acerca del clima que produce incendios forestales en la región tropical andina. Esta investigación cuantifica el peligro de incendios forestales en función de variables climáticas. Para este fin, se empleó el Índice de Peligro de Incendios Forestales de McArthur. Se empleó este índice debido a que no existe un índice local; por otra parte, el mismo está diseñado para bosques de Eucalyptus, los cuales son muy vulnerables ante la ocurrencia de incendios forestales en los Andes de Ecuador. Este estudio determinó que Índice de Peligro de Incendios Forestales de McArthur es una métrica útil para evaluar el riesgo de incendios forestales en la región andina de Ecuador. Usando este índice, esta investigación establece por primera vez mediante un análisis cuantitativo que la temporada de incendios forestales en esta región abarca el período Julio-Noviembre.

Published: September 2019

El cálculo de la incertidumbre combinada de ensayos de flujo luminoso realizados en una esfera integradora es importante para la acreditación bajo los estándares de la norma ISO/IEC 17025. Los valores de los equipos de medición usados dentro del ensayo debían ser registrados de manera manual por el operador, por lo cual se implementó un sistema de adquisición de los datos automático mediante la integración de los equipos en una aplicación desarrollada en LabVIEW que incluye el cálculo de la incertidumbre basado en el modelo desarrollado por el mismo laboratorio y la generación de informes. El presente trabajo analiza la influencia de la automatización del proceso de adquisición, análisis y uso de los datos para el cálculo de la incertidumbre, comparando un ensayo designado de una lámpara de alta descarga usando el sistema manual y el sistema automatizado además de la reducción del tiempo del ensayo para cubrir una mayor demanda.

Authors: Morales Luis , Santamaría Jorge
Published: September 2019

La investigación consiste en analizar la influencia de los paneles modulares M2 en el comportamiento sismo resistente de edificaciones. En un 1°Caso: se consideró al panel M2 como mampostería confinada y en un 2° Caso: como sistemas de pisos (losas). Para ello se emplearon 5 proyectos arquitectónicos diferentes ubicados en Quito. Una vez que los sistemas aporticados planteados alcancen los parámetros sismo resistentes establecidos en la normativa, en un 1° Caso, se incorporan, los paneles modulares M2 como mampostería confinada en edificios de 3, 6 y 9 pisos. Mientras que, en un 2° Caso, se dispuso que el panel modular M2 sea considerado como sistema de piso (losas). De estos dos grupos de edificaciones con diferente disposición de los paneles, se determinan nuevos valores de respuestas estructurales, con cuyos datos se procede a comparar con los resultados obtenidos con el sistema aporticado. Para la colocación de los paneles modulares como mampostería dentro de los sistemas estructurales propuestos se utilizó el método puntal equivalente, donde las paredes trabajan solo axialmente a compresión y no absorben cortante. Mientras que, para los sistemas de pisos, se utilizó como modelo base al sistema de piso con stell deck y otra con la implementación de paneles modulares M2. Para ello se dispuso de dos edificios de mediana altura (6 pisos) y gran altura (16 pisos). Del análisis estructural, para ambos casos: los sistemas aporticados con paneles modulares M2 utilizados tanto como mampostería confinada como sistemas de piso (losas), generó respuestas estructurales como períodos y derivas de piso menores que el sistema solo aporticado, debido a que el panel modular M2 aporta rigidez lateral y disminuye el peso de las edificaciones, demostrando así que: se puede reducir la vulnerabilidad estructural y mejorar el comportamiento estructural de edificaciones ante la acción sísmica.

Many studies have analyzed the association between micro- or macroalbuminuria and the increased risk of cardiovascular disease, but only few examined the association between normoalbuminuria and cardiovascular disease.Objective: To analyze the association between the degree of normoalbuminuria and the occurrence of left ventricular diastolic dysfunction in hypertensive patients.Method: This is cross-sectional analysis in hypertensive patients. Normoalbuminuric subjects are divided into three tertiles based on the cutoff of Urine-Albumin-Creatinine Ratio (UACR). To evaluate left ventricular function, all subjects undergo echocardiography examination. Left ventricular diastolic dysfunction is positive if more than fifty percent of positive findings are present from the fourth parameters stated in the 2016 American Society of Echocardiography criterias.Results: No significant difference in the occurrence of LVDD was found between the two groups according to age, sex, smoking, dyslipidemia, physical activity, BMI, hypertension therapy and HbA1c, but a significant difference was seen in the UACR tertile of the two group. This study showed that upper-limit normoalbuminuria (third tertile) was associated with the occurrence of LVDD (OR 15.57, 95% CI: 2.88-84.25).Conclusion: This study showed that normoalbuminuria in hypertensive population is associated with left ventricular diastolic dysfunction. Keywords: hypertension, normoalbuminuria, left ventricular diastolic dysfunctio

Pemaknaan Agama Komunitas Tombo Ati (Analisis Pemikiran Keagamaan)
Authors: Zuhdi Muhammad
Published: September 2019

Klaim kebenaran Islam secara sepihak terjadi antara lain karena pemaknaan agama yang dilakukan secara tekstual dogmatic dengan mengabaikan aspek kontekstualÂ filosofis, historis, sosiologis dan antropologis. Pemaknaan yang dilakukan secara tekstual dogmatik melahirkan pemahaman keagamaanÂ yangÂ syariat Â sentris Â yangÂ cenderungÂ hitam Â putih Â dalam melihat dan menilai persoalan khususnya yang terkait dengan perbedaan paham atau aliran. Tulisan ini mencoba menyuguhkan sebuah realitas keagamaan yang secara sosiologis merupakan bagian dari masyarakat tapi memiliki perbedaan signifikan khususnya jika dibandingkan dengan aliran mainstream. Realitas tersebut direpresentasikan oleh sebuah komunitas keagamaan yang bernama Komunitas Tombo Ati yang dalam tulisan ini yang dikaji adalah pemikiran keagamaan ketuanya yang bernama Ahmad Luthfi (Gus Luthfi). Teori yang digunakan adalah sosiologi agama dalam perspektif Durkheim dan Nottingham.Â Metode yang digunakan adalah etnometodologi. Tulisan ini menunjukkan bahwa pemaknaan agama Komunitas Tombo Ati memunculkan pemahaman keagamaan yang unik karena lebih lebih mengedepankan aspek intrinsik atau nilai-nilai hakikat dari agama.
