Published: September 2020

Background:

Dillenia indica (Family: Dilleniaceae) is an antioxidant-rich edible fruitbearing
medicinal plant. The fruit of this plant (known as elephant apple) has many uses in traditional
medicine.

Objective:

By considering its antioxidant content and ameliorating effects, this study aimed to evaluate
the anti-adipogenic effects of D. indica fruit extract (DIFE) on high-fat diet (HFD) fed obese
rats.

Methods:

Male Wistar rats were fed with a standard diet (SD), or high-fat diet (HFD), or HFD
with 100 mg/kg or 200 mg/kg or 400 mg/kg DIFE for 8 weeks. The fruit extract was given orally
by feeding gavage. The body weight, liver weight, visceral fat weight, plasma lipids, and oxidative
stress-related parameters were measured. The mRNA level of different adipogenesis related transcription
factors, lipogenic and lipolytic enzymes was also evaluated.

Results:

Consumption of DIFE daily (400 mg/kg) for 8 weeks resulted in a significant reduction of
high-fat diet-induced body weight, liver weight, visceral fat weight, total cholesterol, and LDL-cholesterol
level. High-fat diet-mediated elevation of oxidative stress markers was also lowered,
with a parallel augmentation of the activities of antioxidant enzymes, due to 400 mg/kg DIFE feeding.
DIFE also down-regulated the mRNA level of important pro-adipogenic factors like PPARγ,
LXRα, and SREBP1c which consequently downregulated the transcript levels of lipogenic enzymes:
ACC, FAS, HMGCR, and DGAT. The transcript level of lipolytic enzyme, HSL was also
down-regulated in 400 mg/kg DIFE-fed rats.

Conclusion:

These findings indicate that the antioxidant-rich ethanolic extract of D. indica fruit
can down-regulate the gene expression of pro-adipogenic transcription factors and lipid metabolizing
enzymes and thus can suppress diet-induced obesity in Wistar rat.

Authors: Sheng Lin , Tu Junwei , Sheng Yijun , Zhu Jingqian , Chen Huijun , Tian Jianghua , Wang Lixia , Pan Chuli
Published: September 2020

Background:

Primary tracheal adenoid cystic carcinoma is a rare, slow-growing pulmonary malignancy. Due
to the low incidence, clinicians are poor in the diagnosis and treatment of such disease, which is prone to cause
misdiagnosis or missed diagnosis, consequently leading to delayed treatment.

Case Presentation:

Here, we reported a case of a 72-year-old woman who was diagnosed as primary bronchial adenoid
cystic carcinoma after three years. At the time of final diagnosis, lesion involvement was seen in the entire bronchus and
radical treatment was not available.

Conclusions:

Endoscopic bronchoscopy and palliative radiotherapy can relieve the symptoms of the patient and make the
patient survive with the tumor for a long time.
An Automated Model for Target Protein Prediction in PPI
Authors: Sundar G. Naveen , Narmadha D.
Published: September 2020

Background:

Essential proteins play a crucial role in most of the living organisms. The
computer-based task of predicting essential proteins is important for target protein identification, disease
treatment and suitable drug development.

Objective:

Traditionally many experimental and centrality measures have been proposed by researchers to
predict protein essentiality.

Methods:

The prediction accuracy, sensitivity, specificity identified by the traditional methods
is very low.

Results and Discussion:

In this research work, a novel computational based approach such as NCKNN
model has been proposed to identify the essential proteins. The proposed work uses a combination
of network topology measure and machine learning model to predict the essential proteins.

Conclusion:

The proposed work shows a
remarkable improvement than seven traditional centrality based measures such as DC, BC, CC, EC, NC, ECC and SC in
terms of the metrics such as accuracy(A1), precision(P1), recall(R1), sensitivity(SE) and specificity(SP).

Evaluation of the MoMba Live Long Remote Smoking Detection System During and After Pregnancy: Development and Usability Study
Authors: Valencia Stephanie , Callinan Laura , Shic Frederick , Smith Megan
Published: September 2020

Background

The smoking relapse rate during the first 12 months after pregnancy is around 80% in the United States. Delivering remote smoking cessation interventions to women in the postpartum period can reduce the burden associated with frequent office visits and can enable remote communication and support. Developing reliable, remote, smoking measuring instruments is a crucial step in achieving this vision.

Objective

The study presents the evaluation of the MoMba Live Long system, a smartphone-based breath carbon monoxide (CO) meter and a custom iOS smartphone app. We report on how our smoking detection system worked in a controlled office environment and in an out-of-office environment to examine its potential to deliver a remote contingency management intervention.

Methods

In-office breath tests were completed using both the MoMba Live Long system and a commercial monitor, the piCO+ Smokerlyzer. In addition, each participant provided a urine test for smoking status validation through cotinine. We used in-office test data to verify the validity of the MoMba Live Long smoking detection system. We also collected out-of-office tests to assess how the system worked remotely and enabled user verification. Pregnant adult women in their second or third trimester participated in the study for a period of 12 weeks. This study was carried out in the United States.

Results

Analyses of in-office tests included 143 breath tests contributed from 10 participants. CO readings between the MoMba Live Long system and the piCO+ were highly correlated (r=.94). In addition, the MoMba Live Long system accurately distinguished smokers from nonsmokers with a sensitivity of 0.91 and a specificity of 0.94 when the piCO+ was used as a gold standard, and a sensitivity of 0.81 and specificity of 1.0 when cotinine in urine was used to confirm smoking status. All participants indicated that the system was easy to use.

Conclusions

Relatively inexpensive portable and internet-connected CO monitors can enable remote smoking status detection in a wide variety of nonclinical settings with reliable and valid measures comparable to a commercially available CO monitor.

Real-World Implications of a Rapidly Responsive COVID-19 Spread Model with Time-Dependent Parameters via Deep Learning: Model Development and Validation
Authors: Jung Se Young , Jo Hyeontae , Son Hwijae , Hwang Hyung Ju
Published: September 2020

Background

The COVID-19 pandemic has caused major disruptions worldwide since March 2020. The experience of the 1918 influenza pandemic demonstrated that decreases in the infection rates of COVID-19 do not guarantee continuity of the trend.

Objective

The aim of this study was to develop a precise spread model of COVID-19 with time-dependent parameters via deep learning to respond promptly to the dynamic situation of the outbreak and proactively minimize damage.

Methods

In this study, we investigated a mathematical model with time-dependent parameters via deep learning based on forward-inverse problems. We used data from the Korea Centers for Disease Control and Prevention (KCDC) and the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University for Korea and the other countries, respectively. Because the data consist of confirmed, recovered, and deceased cases, we selected the susceptible-infected-recovered (SIR) model and found approximated solutions as well as model parameters. Specifically, we applied fully connected neural networks to the solutions and parameters and designed suitable loss functions.

Results

We developed an entirely new SIR model with time-dependent parameters via deep learning methods. Furthermore, we validated the model with the conventional Runge-Kutta fourth order model to confirm its convergent nature. In addition, we evaluated our model based on the real-world situation reported from the KCDC, the Korean government, and news media. We also crossvalidated our model using data from the CSSE for Italy, Sweden, and the United States.

Conclusions

The methodology and new model of this study could be employed for short-term prediction of COVID-19, which could help the government prepare for a new outbreak. In addition, from the perspective of measuring medical resources, our model has powerful strength because it assumes all the parameters as time-dependent, which reflects the exact status of viral spread.
Behavior Change Techniques in Wrist-Worn Wearables to Promote Physical Activity: Content Analysis
Authors: Düking Peter , Tafler Marie , Wallmann-Sperlich Birgit , Sperlich Billy , Kleih Sonja
Published: September 2020

Background

Decreasing levels of physical activity (PA) increase the incidences of noncommunicable diseases, obesity, and mortality. To counteract these developments, interventions aiming to increase PA are urgently needed. Mobile health (mHealth) solutions such as wearable sensors (wearables) may assist with an improvement in PA.

Objective

The aim of this study is to examine which behavior change techniques (BCTs) are incorporated in currently available commercial high-end wearables that target users’ PA behavior.

Methods

The BCTs incorporated in 5 different high-end wearables (Apple Watch Series 3, Garmin Vívoactive 3, Fitbit Versa, Xiaomi Amazfit Stratos 2, and Polar M600) were assessed by 2 researchers using the BCT Taxonomy version 1 (BCTTv1). Effectiveness of the incorporated BCTs in promoting PA behavior was assessed by a content analysis of the existing literature.

Results

The most common BCTs were goal setting (behavior), action planning, review behavior goal(s), discrepancy between current behavior and goal, feedback on behavior, self-monitoring of behavior, and biofeedback. Fitbit Versa, Garmin Vívoactive 3, Apple Watch Series 3, Polar M600, and Xiaomi Amazfit Stratos 2 incorporated 17, 16, 12, 11, and 11 BCTs, respectively, which are proven to effectively promote PA.

Conclusions

Wearables employ different numbers and combinations of BCTs, which might impact their effectiveness in improving PA. To promote PA by employing wearables, we encourage researchers to develop a taxonomy specifically designed to assess BCTs incorporated in wearables. We also encourage manufacturers to customize BCTs based on the targeted populations.
Las prácticas corporales y el racismo colorista en el contexto mediático en México
Authors: Tipa Juris
Published: September 2020

Basándose en investigación bibliográfica y entrevistas cualitativas con actores y modelos, en el presente artículo se analiza la relación entre las representaciones mediáticas en México y las prácticas corporales. La importancia de este análisis se debe al hecho de que las representaciones mediáticas visuales participan en la creación de un imaginario sobre lo significante y lo insignificante, lo que posteriormente se impregna socialmente en la percepción corporal cotidiana, tanto al nivel individual como colectivo.
Se concluye que dichas representaciones se caracterizan por un constante racismo colorista, lo cual fomenta una exclusión simbólica de los "otros" cuerpos e indirectamente normaliza el racismo y el clasismo colorista en la sociedad mexicana; entre otras de sus expresiones, en forma de modificaciones corporales para acercarse al imaginario impuesto de lo deseado que puede estar relacionado con las históricas desigualdades socioeconómicas en México.
A representação dos heróis nacionais mexicanos na obra poética de Castro Alves
Authors: Lima Baca Francisco
Published: September 2020

A imagem dos heróis mexicanos na poesia brasileira do século XIX estabelece o ponto de encontro e diálogo entre as expressões literárias desenvolvidas na América Latina. As categorias “missão do romancista” e “missão do poeta” definem a função da literatura na formação dos diversos projetos nacionais criados nas novas nações latino-americanas. Para os artistas a literatura foi uma ferramenta para definir um projeto de identidade nacional nas diversas regiões do continente e no caso do Brasil, a poesia foi um elemento fundamental para definir aos novos heróis latino-americanos. A comparação das diversas expressões poéticas criadas no Brasil, no Peru e no México estabelecem um diálogo a partir de uma metodologia de analises hermenêutica que, no caso do texto: “Poema e diálogo” de Gadamer e das reflexões de Eduardo F. Coutinho colocam em questão as semelhanças e as diversas interpretações dos heróis que encarnam projetos de estados que se encontram na constante procura da sua independência e reconhecimento.

¡Ellas tienen los escaños, ellos el poder! Representación legislativa de las mujeres en el estado de Morelos
Authors: Freidenberg Flavia , Gilas Karolina
Published: September 2020

Este artículo estudia la representación política en el estado de Morelos, donde han sido electas el mayor número de mujeres tras la aprobación de la paridad de género entre 2014 y 2019. Esta entidad federativa incrementó 162 % el número de mujeres electas desde 1997, convirtiéndose en el Legislativo subnacional con más mujeres en el país. La expectativa era que un mayor número de mujeres en el Congreso impulsaría iniciativas orientadas a reducir la brecha de género y promover igualdad sustantiva. Los resultados de esta investigación dan cuenta de lo contrario. A pesar de tener el mayor número de legisladoras de su historia, y en comparación con el resto de los estados, el Congreso de Morelos no ha podido avanzar en términos de representación simbólica ni sustantiva. A partir de este estudio de caso y con el objetivo de evaluar de manera multidimensional la implementación de la paridad de género, se evidencia que, a pesar de las transformaciones normativas realizadas, los obstáculos (institucionales, partidistas y actitudinales) persisten e impiden que las mujeres participen en igualdad con los hombres dentro de la política morelense.
El movimiento feminista en México en el siglo XXI: juventud, radicalidad y violencia
Authors: Álvarez Enríquez Lucia
Published: September 2020

Este trabajo aborda el análisis del movimiento feminista recientemente generado en México (2019-2020), protagonizado inicialmente por mujeres jóvenes en el interior de la Universidad Nacional Autónoma de México, teniendo como núcleo central de sus demandas la denuncia y el alto a la violencia contra las mujeres. En la segunda mitad de 2019, este movimiento realizó numerosas movilizaciones y llevaron al paro a varias escuelas universitarias; y salieron a las calles, convocando a colectivos y actores/as sociales muy diversos. Se trata de un movimiento “de nuevo tipo”: con un/a actor/a protagónico/a peculiar, diversificado y, en muchos sentidos, diferente a los movimientos feministas anteriores, sin un liderazgo específico y unificado, y que se ha desplegado con un lenguaje “propio”, directo y confrontativo, recurriendo incluso al uso de la violencia como medio de “comunicar y sacudir”. Es un movimiento que ha conseguido impactar a la opinión pública, y otros logros significativos, como llamar la atención de las autoridades y generar ciertos cambios institucionales y normativos.
La perspectiva de género en el estudio de la ciencia política mexicana (2010-2020)

Published: September 2020

Hay pocos estudios que indagan la participación de las mujeres en la ciencia y son aún más escasos aquellos que reflexionan sobre el papel de las mujeres en el desarrollo de las disciplinas. En este trabajo destacamos dos aspectos del campo de la ciencia política mexicana: primero, las investigaciones con perspectiva de género, y segundo, la construcción de conocimiento que emprenden las mujeres. Se trata de una investigación de carácter exploratorio y descriptivo cuyo estudio de caso es la Universidad Nacional Autónoma de México (UNAM) durante el periodo 2010-2020. Se analizan dos criterios: 1) los artículos publicados en dos revistas especializadas: la Revista Mexicana de Ciencias Políticas y Sociales y la Revista Estudios Políticos, y 2) los temas de género que fueron seleccionados para la elaboración de investigaciones para obtener el título de licenciatura en Ciencias Políticas y Administración Pública con especialidad en Ciencia Política, así como los grados de maestría en Estudios Políticos y Sociales y en el doctorado en Ciencias Políticas y Sociales con orientación en Ciencia Política. Los resultados muestran que el impacto del feminismo, la perspectiva de género y los estudios de género tienen una resonancia importante. Sin embargo, los objetos de estudio hegemónicos per- manecen estables y este campo de investigación, de la mano con las metodologías feministas, aún lucha por abrirse paso en la disciplina.
Causas de Apatía en Parejas Casadas y en Unión Libre
Authors: Aguilar Montes de Oca Yessica Paola
Published: September 2020

El objetivo fue determinar las causas que conducen a la apatía en la pareja haciendo un análisis por sexo. Se trabajó con una muestra no probabilística intencional, compuesta por 150 participantes, igualmente dividida por sexo, quienes reportaron estar casados o vivir en unión libre y tener hijos, de la ciudad de Toluca, México. Se utilizó un cuestionario compuesto por 6 frases incompletas el cual fue validado por jueces expertos con un nivel de acuerdo mayor del 85%. Las aplicaciones fueron individuales en lugares públicos de la ciudad, previa firma del consentimiento informado. Se encontró que las causas que generan apatía en la pareja se deben a la falta de involucramiento, la falta de novedad, la realización de actividades no estimulantes, los conflictos, el cansancio, la falta de atracción sexual y a factores externos. Es interesante señalar que a pesar de reportar apatía y estar sin gusto y con queja muchos permanecen en su relación. Así, el estudio de la apatía puede ser útil para incentivar a las parejas a utilizar estrategias para recuperar el interés dentro de la relación o bien, a decidirse terminar con ésta para buscar la satisfacción de sus necesidades o carencias y alcanzar la paz o el equilibrio personal.

Published: September 2020

Esta investigación tuvo por objetivo analizar un modelo explicativo de la masculinidad juvenil y su relación con la disposición a la delincuencia, la escolaridad y el interés en actividades exctracurriculares socioculturales. La investigación de tipo cuantitativa usó un diseño no experimental, correlacional y transversal, por medio de la aplicación de escalas de medición en una muestra de 172 jóvenes en situación de riesgo delictivo entre los 14 y 25 años participantes en el programa Jovenes por la igualdad de SUPERA-USAID en Monterrey, Nuevo León, México. Se utilizó el Modelamiento de ecuaciones estructurales por medio del AMOS versón 21 para analizar la información. Los resultados incluyen en un primer momento la relación postiva entre los años de estudio (B=.25, p=.026) y el interés por actividades socioculturales (B= .29, p=.026) con expresiones de masculindad igualitaria juvenil, y posteriormente la masculinidad igualitaria juvenil impacta de manera negativa en la disposición a la delincuencia juvenil (B= -.52, p= .026), es decir entre mayores expresiones de una masculinidad tradicional juvenil mayor disposición a la delincuencia juvenil (CFI=.95, TLI=.931, RMSEA= .043, gl=. 87, Chi Cuadrada=114.3).
Marital Satisfaction in Spanish and Dominican Couples
Authors: Jenaro Cristina
Published: September 2020

Marriage is an appreciated worldwide institution, although nearly half of first marriages end in divorce. Thus, the relevance of understanding how people choose their partners and what features can predict a satisfactory relationship. More specifically, in search of data supporting similarity or complementarity approaches on marital satisfaction, the current study analyzes the association between different assortative mating options (homogamy, and heterogamy) and marital satisfaction in Spanish and Dominican couples. A stratified quota sampling of 600 participants was selected, corresponding to 300 married couples (50% Spanish and 50% Dominicans). Data were gathered by means of an interview with the 10-item scale on Marital Satisfaction and a 7-item scale on Status. Results suggest that spouses are matched by similarity in their health and education and by the perception of similarity in intelligence and the financial advantages of staying together. Dominican couples experienced higher marital satisfaction than Spanish couples. Findings on hypergamy reveals the persistence of some traditional roles’  distribution among Spanish speaking cultures. The association between status and marital satisfaction revealed that heterogamy rather than homogamy is associated to such satisfaction. These results stress the relevance of taking into account social and cultural differences, beyond biological and psychological factors, to fully understand couples’ satisfaction.
Memoria de Trabajo e Inteligencia General Fluida en un Grupo de Escolares del Nivel Primario
Authors: Medina Curi Nicolás
Published: September 2020

El presente estudio tiene dos objetivos: a) Construir un Test de Capacidad de Lectura –TCL, para medir el nivel de memoria de trabajo (MT) y b) analizar la relación entre MT y la inteligencia general fluida –Gf (medido a través de Test de Matrices  Progresivas de Raven, para niños), en un grupo de 124 niños lectores escolarizados del nivel primario. Dado el carácter primordial de este segundo objetivo, se procedió a emplear el método correlacional, que sugiere la medición y descripción de las variables MT y Gf, cuyo índice correlacional establece el nivel de dicha relación. En cuanto a la justificación de la presente tesis, se sustenta en la constatación empírica de la presencia previa de la MT, como un factor explicativo de la varianza que sufre la Gf. La validez de contenido del nuevo TCL se estableció mediante el criterio de juicio de expertos; mientras que, la confiabilidad del mismo instrumento está dentro del nivel de confianza y seguridad. Finalmente, se puede afirmar que la relación entre MT y Gf es sustancial, en la medida que sugiere que la MT es un factor importante que explica la varianza de los puntajes Gf.
Autonomy Development: Gender and Age Differences from Adolescence to Emerging Adulthood
Authors: Dutra-Thomé Luciana , Marques Louise Florêncio , Seidl-de-Moura Maria Lucia , De Oliveira Ramos Dandara , Koller Silvia
Published: September 2020

The development of autonomy during the transition to adulthood may present itself in different forms, depending on age, gender and cultural variations. Grounded in developmental psychology, this study examined gender and age differences in autonomy in Brazilian youth. Participants were 154 Brazilian adolescents and emerging adults (14-33 years old, M= 20.87, SD= 3.74, 50% female) from the state capital of Rio de Janeiro. Our findings indicate a positive association between age and autonomy scores in the Kağitçibaşi’s Autonomous, Related and Related-autonomous Self scales. Correlation results showed gender specific results in such associations, such as that for men, age was positively associated with autonomy, whereas for women, it was associated with related-autonomy. These results suggest that, in Brazil, traditional views continue to reinforce gender roles towards men’s agentic behavior and women’s communal behavior. These findings highlight the importance of elucidating gender differences in the development of autonomy in different sociocultural contexts.
Assessment of the General Response Style: A Cross-Cultural Validation
Authors: He Jia , Van de Vijver Fons J.R.
Published: September 2020

Surveys that use self-reports are susceptible to response styles. The assessment and validation of response styles would benefit from a brief measure that captures the general tendency of responding. Going beyond the traditional view that response styles amount to deliberate impression management or lying, we propose to assess and conducted a validation of brief general response style (GRS) scales which are conceptualized as a trait-like communication style preference, in multiple cultural contexts. With university student data on the GRS measure, indirect measures of GRS, and personality and values, we found that (1) this direct measure of GRS showed acceptable internal consistency and comparable factor structure across countries (metric invariance); (2) although it did not correlate strongly with the indirect measure of GRS, it showed similar mean difference patterning across countries, with a lower level of GRS in China than Mexico and the Netherlands, and (3) in line with the trait-like conceptualization, the direct GRS was associated with being extravert, open, and valuing self-enhancement. We discuss the potential usefulness of the direct GRS measure in surveys involving different groups.
Emerging Adulthood Features in Brazilians from Differing Socioeconomic Status
Authors: Dutra-Thomé Luciana , Koller Silvia Helena
Published: September 2020

The present study aimed at investigating emerging adulthood features in Brazilians from low and high socioeconomic statuses (SESs). The sample was 547 Southern Brazilians; residents in the urban context, between 18 and 29 years old (Md = 22 years; IQR = 7), 64.2% females. From this sample, 13 participants were randomly selected to participate on the qualitative study. Instruments were the Brazilian Version of the Inventory of Dimensions of Emerging Adulthood, a Semi-structured interview, and the variable socioeconomic status (SES) from the Brazilian Adolescence and Youth Questionnaire. Analysis from Structural Equation Modeling (SEM) indicated no associations between SES and IDEA dimensions. Deductive thematic analysis revealed the presence of emerging adulthood features in Brazil (general Kappa = .83) and that economic disparities affected youth developmental trajectories. High SES individuals were more likely to experience EA features according to what has been observed in industrialized countries. Low SES individuals presented a divergent trend, because their opportunities to live a period of identity exploration would happen after an other-focused period. The transition to adulthood considered as a nonlinear process influenced by the socioeconomic context is discussed.
Incertidumbre: Efectos del Apego Romántico sobre la Vigilancia de la Pareja en Redes
Authors: García Meraz Melissa
Published: September 2020

La Vigilancia Electrónica Interpersonal (VEI) en Redes Sociales se refiere a una serie de estrategias para monitorear el comportamiento de la pareja en redes. La investigación señala que existe una relación entre el apego ansioso y esta vigilancia, sin embargo, existe poca investigación relacionada al efecto diferencial del sexo, así como el efecto específico sobre la red social Facebook. Por ello, el objetivo de esta investigación fue crear un modelo de ecuación estructural para explorar la relación entre la VEI, la Búsqueda de Información en Facebook BIF y los estilos de apego en hombres y mujeres. Las escalas se administraron a 835 estudiantes universitarios. Los análisis indicaron la unidimensionalidad y buen ajuste de la VEI [X2 (44) = 269.8, p> .05, CFI = .955, SRMR = .031, RMSEA = .078], la BIF [X2 (44) = 1945.4, p> .05, CFI = .998, SRMR = .010, RMSEA = .028] y el Apego [X2 (136) = 4629.7, p> .05, CFI = .942, SRMR = .053, RMSEA = .052]. La ecuación mostró que la ansiedad predice la VEI y BIF en hombres y mujeres, con coeficientes mayores en estas últimas. Se enfatiza la importancia de la medición relacionada con la vigilancia y sus implicaciones.

Published: September 2020

The application of  liquid compost and of beneficial soil microorganism such as arbsucular mycorrhizal fungi can be used to replace chemical fertilizer application. The aim of this study was to investigate the growth of red onion (Allium cepa L.) plant fertilized by liquid compost and  inoculated by arbuscular mycorrhizal fungi. This study was conducted based on a completely randomized design with two factors. The first factor was an addition of liquid compost dosages (0, 50, 100 and 200 ml/polybag). The second factor was an addition of AM fungal inoculum (with and without addition). The results showed that the growth of red onion plant was not significantly affected by the addition of liquid compost and AM fungal inoculum.  However,  the red onion plant fertilized by 200 ml liquid compost per polybag had the lowest shoot dry weight. The addition of AM fungal inoculum was not increasing plant growth because the quality of used inoculum was not good.

Utilizing of lycopene extract in VCO has serve as antioxidant agent that protected VCO from oxidation process during storage. Belnding of VCO and tomato lycopene extract has been done that purpose to determine changes in peroxide number in the mixture of VCO-lycopene extract tomatoes based on comparison of ratios and length of storage. Peroxide contents from the mixture of tomato extract with VCO were determined using a spectrophotometric method at a wavelength of 500 nm. The results showed that the best results were obtained at a ratio of 40: 3 (v/w) with peroxide numbers 0.08 meq O2/ kg, 1.38 meq O2/ kg, 1.84 meq O2/ kg, 3.21 meq O2/ kg, 3.46 meq O2/ kg and 3.83 meq O2/ kg respectively. Peroxide numbers increased with increasing storage time, the highest increase occurred at week 3 at a ratio of 40: 1 (v/w) which was equal to 9.62 meq O2/ kg. The addition of lycopene was better at reducing the VCO oxidation process than without the addition of lycopene.

Microcomputed tomography cortical bone evaluation for craniofacial implantology
Authors: Ivanjac Filip , Konstantinovic Vitomir
Published: September 2020

Introduction. Good implant stability is one of the most important factors for successful implant therapy. This precondition is important for all kinds of implants, oral and extra-oral, i.e. craniofacial implants as well. One of the most important factors for satisfactory implant stability is the bone quality, particularly of the cortical bone, which is determined by its microarchitectural parameters. The aim of this paper was to assess cortical bone microarchitectural parameters in the targeted regions for craniofacial implant placement. Methods. Bone quality on targeted locations was determined by the micro-CT method on a cadaver model. The target places for implant placement were the periorbital, the perinasal, and the periauricular region. Microarchitectural parameters included cortical thickness (Ct.Th.), cortical porosity (Ct.Po.), pore diameter (Po.Dm.), and pore separation (Po.Sp.). Results. The smallest Ct.Po. (4.1%) and the largest Po.Sp. (0.5 mm) were determined in glabella. The maximum Ct.Th. (2.7 mm) as well as Po.Dm. (0.2 mm) were found in the zygomatic region. The mastoid part of the temporal bone showed the smallest Ct.Th. (1.2 mm) and Po.Sp. (0.3 mm). The highest Ct.Po. was in the perinasal region (8.5%). Conclusion. The bone quality measured through microarchitectural parameters was good in all the regions of interest for the disk- and screw-shape extra-oral implant anchorage.

Introduction/Objective. We aimed to investigate the effects of diabetes mellitus (DM) on rat dental pulp repair by measuring time-dependent changes in expressions of vascular endothelial growth factor (VEGF) and bone morphogenetic protein 2 (BMP 2) following direct pulp capping. Methods. Two groups, each of 20 Wistar rats, received either streptozotocin (for DM induction) or the same volume of sterile saline. A week later, the pulp of maxillary and mandibular right incisors in diabetic and non-diabetic groups were exposed and capped with calcium hydroxide in order to provoke reparative response. The levels of VEGF and BMP 2 were determined in the pulp tissue lysates one and seven days after the pulp capping, using enzyme-linked immunosorbent assays. Results. Diabetic state per se increased VEGF level, with a peak at first day after the pulp capping (19.3 ? 0.9 pg/mg, p < 0.001), but did not affect BMP 2 levels. Significant increase of BMP 2 expression was noticed on the seventh day in capped pulp, but only in diabetic rats (16.7 ? 1 pg/mg, p = 0.001). Positive correlation between VEGF and BMP 2 was found on the seventh day following capping, only in diabetic pulp (r = 0.905, p = 0.003). Conclusion. Diabetes-induced increase in VEGF expression reflects changes in the inflammatory phase of pulp repair in DM. Increase in BMP 2 expression suggest that stimulating effect of calcium hydroxide appears seven days after diabetic pulp capping.

Published: September 2020

Aero-thermal optimization on multi-rows of film cooling over a flat plate has been performed to optimize the inclination angles. Hence three cylindrical holes with injection angles of ?, ?, and ? have been considered. The cooling hole has a 3 mm diameter and an inclined angle between 25-35?. Numerical simulations were performed at a fixed density ratio of 1.25 and blowing ratio of 0.5. The control-volume method with a SIMPLEC algorithm has been used to solve the steady-state RANS equations with SST k-? turbulent model. The injection angles of the holes are selected as the design variables to perform the optimization of three rows of film cooling. In order to evaluate the performance of holes arrangement, two objective functions are defined based on aerodynamic losses and adiabatic film cooling effectiveness. The curve fitting method is used to find the optimal point of objective functions. The optimizations have been performed using the genetic algorithm method. Results of the present study show that the best performance of three rows of cooling holes was achieved in inclined angles 25.45, 32.85, and 33.1.

The Global Energy Crisis necessitated improving research into new, renewable and alternative energy sources. Due to that, our focus is on the area of some phenomena and applications where different synthetic methods and micro-structure property optimization achieved significant improvement in the electro physical properties of output materials and components. This is especially important for higher energy efficiency and electricity production (batteries and battery systems, fuel cells, and hydrogen energy).The improvement of energy storage tank capacity is one of the most important development issues in the energy sphere too. It is because of this very promising research and application area that we are expanding the knowledge on these phenomena through fractal nature analysis. So, the results obtained in the field of electrochemical energy sources, especially in electrolyte development, are taken into account the analysis of fractal nature optimization. Based on the research field of fractal material science, particularly electronic materials, we conducted research in micro-structure fractal influence in the area of electrochemistry. We investigated the consolidation parameters of Fe2O3 redox processes. The influence of activation energy, fundamental thermodynamic parameters, and also the fractal correction of electrode surface area through complex fractal dimension with recognized grains and pores, and the Brownian motion of particles is introduced. Finally, the electrochemical Butler-Volmer equation fractalization is obtained. These results practically open new frontiers in electrochemical energy processes performed through the Arrhenius equation within electrolyte bulk and electrode relations and more complete and precise energy generation.
Heat conduction in rectangular solids with internal heat generation
Authors: Duan Zhipeng , Ma Hao
Published: September 2020

A representative steady-state heat conduction problem in rectangular solids with uniformly distributed heat generation has been investigated analytically. An analytical solution is provided by solving a non-homogeneous PDE. A simple and accurate model is proposed to predict the dimensionless shape factor parameter for the first time. The dimensionless shape factor is obtained in the light of the solution of Poisson equation with constant wall temperature boundary conditions. The area-mean temperature is found by integration on the rectangular cross-section. The model is very concise and nice for quick real world approximations, and it provides acceptable accuracy for engineering practice.

The aim of paper was to discuss contribution of bi-fuel CNG powered light commercial vehicles to the well-to-wheel CO2 equivalent emissions, both today and in the coming decades in which the development of new fuels and new vehicles is expected. Field research was done in Belgrade, during one year, using Euro 5 diesel/LPG/CNG light commercial vehicles driving under low vehicle speed, low engine load, low exhaust gas temperature and high number of stops. The well-to-wheel as neutral methodology was applied for understanding of each fuel path-way in terms of reducing greenhouse gas emissions and increasing energy efficiency. Calculation showed that total energy consumption per kilometre is the lowest for diesel vehicles since petrol/LPG and petrol/CNG vehicles use 21% and 7% more energy. Tank-to-wheel emission of CO2 equivalent is most favorable for petrol/CNG with 28.8% and 6.7% less CO2 equivalent with petrol/LPG and diesel vehicles. The same conclusion brings well-to-wheel analysis showing that diesel/CNG CO2 equivalent emission is 13.5% less than petrol/LPG, apropos 1.5% less than diesel operated vehicles considered within this field research. Figures are not as high as previous, due to the results of well-to-tank emission, that were most favorable for petrol/LPG powered vehicles, with almost 51% and 32% better results regarding to petrol/CNG and diesel, respectively. Within same time, lowest fuel cost per kilometre was achieved by petrol/CNG vehicles, with 32% and 35% less cost than petrol/LPG and diesel vehicles. The available CNG technology should not be neglected, waiting for new solutions to be proven.

Introduction. Individuals who have been identified as frail have an increased state of vulnerability, often leading to adverse health events, increased health spending, and potentially detrimental outcomes.

Objective. The objective of this work is to develop and validate a case definition for frailty that can be used in a primary care electronic medical record database.

Methods. This is a cross-sectional validation study using data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) in Southern Alberta. 52 CPCSSN sentinels assessed a random sample of their own patients using the Rockwood Clinical Frailty scale, resulting in a total of 875 patients to be used as reference standard. Patients must be over the age of 65 and have had a clinic visit within the last 24 months. The case definition for frailty was developed using machine learning methods using CPCSSN records for the 875 patients.

Results. Of the 875 patients, 155 (17.7%) were frail and 720 (84.2%) were not frail. Validation metrics of the case definition were: sensitivity and specificity of 0.28, 95% CI (0.21 to 0.36) and 0.94, 95% CI (0.93 to 0.96), respectively; PPV and NPV of 0.53, 95% CI (0.42 to 0.64) and 0.86, 95% CI (0.83 to 0.88), respectively.

Conclusion. The low sensitivity and specificity results could be because frailty as a construct remains under-developed and relatively poorly understood due to its complex nature. These results contribute to the literature by demonstrating that case definitions for frailty require expert consensus and potentially more sophisticated algorithms to be successful
