Authors: Chou Wen-Jiun , Huang Mei-Feng , Chang Yu-Ping , Chen Yu-Min , Hu Huei-Fan , Yen Cheng-Fang
Published: March 2017

Background and aims

The aims of this study were to examine the association between social skills deficits and Internet addiction and activities in adolescents with attention-deficit/hyperactivity disorder (ADHD) as well as the moderators for this association.

Methods

A total of 300 adolescents, aged between 11 and 18 years, who had been diagnosed with ADHD participated in this study. Their Internet addiction levels, social skills deficits, ADHD, parental characteristics, and comorbidities were assessed. The various Internet activities that the participants engaged in were also examined.

Results

The associations between social skills deficits and Internet addiction and activities and the moderators of these associations were examined using logistic regression analyses. Social skills deficits were significantly associated with an increased risk of Internet addiction after adjustment for the effects of other factors [odds ratio (OR) = 1.049, 95% confidence interval (CI) = 1.030–1.070]. Social skills deficits were also significantly associated with Internet gaming and watching movies. The maternal occupational socioeconomic levels of the participants moderated the association between social skills deficits and Internet addiction.

Conclusions

Social skills deficits should be considered targets in prevention and intervention programs for treating Internet addiction among adolescents with ADHD.

Synthesis of Flower-like Silver Nanostructures on Silicon and Their Application in Surface-enhanced Raman Scattering
Authors: Minh Kieu Ngoc , Anh Cao Tuan , Ngan Luong Truc Quynh , Vu Le Van , Cao Dao Tran
Published: March 2017

To enhance the intensity of surface-enhanced Raman scattering (SERS), production of metal nanostructures with sharp points, lying side by side at the nanometer level plays an extremely important role. In this paper, we report on a manufacturing process in which the silver nanoparticles with the flower-like shape have been fabricated. Such silver nanoparticles have been fabricated by chemical deposition of silver particles on silicon wafers, using a solution of hydrofluoric acid (HF), silver nitrate (AgNO3) and ascorbic acid (AsA) in water, at room temperature. During the manufacturing we found that only when the concentrations of AgNO3 and AsA are appropriate, the flower-like silver nanoparticles will form. Note that while other authors mainly made flower-like silver nanoparticles in the form of suspensions, we have created flower-like silver nanoparticles with cabbage-shape on a silicon surface. The ensembles of flower-like silver nanoparticles above were used as SERS substrates to detect crystal violet (CV) in low concentrations and good results were obtained.

Revisión: Fibroína de seda y sus potenciales aplicaciones en empaques biodegradables para alimentos/Review: silk fibroin and their potential applications on biodegradable food packaging
Authors: Rios Osorio Angel Daniel , Alvarez-Lopéz Catalina , Cruz Riaño Luis Javier , Restrepo-Osorio Adriana
Published: March 2017

En el presente artículo se hace una revisión bibliográfica de la fibroína de seda (FS) y sus potenciales aplicaciones en empaques biodegradables de alimentos. Son cuatro temas principales en los que se centra el artículo: empaques, biopolímeros en empaques, FS y finalmente, la FS en empaques para alimentos. Razones como el cuidado del medioambiente y uso responsable de los recursos, al igual que la necesidad de desarrollar materiales biodegradables, han promovido investigaciones con diferentes biopolímeros, entre los que se encuentra la FS. Esta proteína representa cerca del 70% de la fibra de seda y puede ser obtenida a partir de capullos de primera calidad o de los desperdicios generados en la producción serícola. Dependiendo del método con el que se obtenga la FS, se pueden tener diferentes características fisicoquímicas que pueden diversificar las áreas de interés y las aplicaciones de la misma. En el caso de empaques para alimentos, la FS puede conferirle al empaque ciertas propiedades, como: aumento de la permeabilidad de oxígeno, resistencia a la rotura, efecto antimicrobiano y una mayor velocidad de degradación del biopolímero.

Influencia del Ce en la hidrodesulfuración de tiofeno utilizando precursores catalíticos de heteropolioxomolibdatos de níquel tipo Anderson soportados sobre alúmina/Influence of Ce in the thiophene hydrodesulfurization using catalytic precursor of alumina
Authors: Polo Hernández Andrés , Puello polo Esneyder , Diaz Carlos
Published: March 2017

El efecto del soporte modificado con cerio en precursores catalíticos de NiMo tipo Anderson sobre la hidrodesulfuración de tiofeno fue investigada. Los sólidos fueron caracterizados por área específica (SBET), difracción de rayos X (DRX) y espectroscopía infrarroja (FTIR). El soporte modificado con cerio se impregnó con una solución acuosa del heteropolioxomolibdato tipo Anderson de Ni. La presencia de (NH4)4[NiMo6O24H6]•5H2O y alúmina en fases gamma y gibbsita se verificó por DRX, mientras que el FTIR permitió asignar las características vibracionales de la estructura tipo Anderson, debido a los estiramientos y flexiones de los grupos funcionales presentes. Los soportes γ-Al2O3, γ-Al2O3-Ce y Ce/γ-Al2O3 mostraron mayor área específica (149-66 m2/g) que los precursores catalíticos NiMo6/γ-Al2O3, NiMo6/γ-Al2O3-Ce y NiMo6-Ce/γ-Al2O3 (76-36 m2/g). Los catalizadores provenientes de alúminas modificadas con cerio presentaron mayor actividad HDS que los obtenidos con alúmina no modificada, lo cual está asociado a la formación de mayor número de sitios activos.

Authors: Albis Arrieta Alberto Ricardo , Martínez Jader , Santiago Pablo
Published: March 2017

Se realizó un estudio en una columna de lecho fijo a escala de laboratorio para determinar el comportamiento  del tiempo de ruptura para la adsorción de Zinc (II) en soluciones acuosas usando como lecho cáscara de yuca (Manihot esculenta), la cual fue pretratada y posteriormente caracterizada. Se evaluó la influencia de la variación de parámetros como la altura del lecho (7 - 23 cm), la concentración inicial de Zinc (II)  (132 - 468 mg/L) y el flujo de alimentación  (7 - 23 mL/min) para determinar el comportamiento del tiempo de ruptura. Los resultados de los experimentos muestran que hay un mayor rendimiento cuando se utilizan el flujo de alimentación y la concentración inicial más bajos, así como la mayor altura del lecho con cáscara de yuca. El tiempo de ruptura óptimo (25 min) se alcanza con una concentración inicial de Zinc de 480.23 mg/L, un caudal de alimentación de 23.35 mL/min y una altura de lecho de 12.86 cm, que constituyen la mejor configuración de parámetros. Adicionalmente, se determinó que el comportamiento del tiempo de ruptura puede ser completamente predicho en los rangos de interés por el modelo BDST.

Authors: Hecht J. Randolph , Benson Al B. , Vyushkov Dmitry , Yang Yingsi , Bendell Johanna , Verma Udit
Published: March 2017

Lessons Learned

The safety profile in the patient groups who received FOLFIRI and simtuzumab did not differ from that in the FOLFIRI and placebo group. The addition of simtuzumab to chemotherapy with FOLFIRI does not improve clinical outcomes in patients with metastatic KRAS mutant colorectal carcinoma.

Background

Simtuzumab, a humanized IgG4 monoclonal antibody to lysyl oxidase-like 2 (LOXL2), blocks desmoplastic reaction in colorectal carcinoma (CRC) cells in vitro.

Methods

Patients with metastatic Kirsten rat sarcoma viral oncogene homolog (KRAS) mutant CRC were randomized to receive second-line 5-fluorouracil, leucovorin, and irinotecan (FOLFIRI) with either 200 or 700 mg simtuzumab or placebo every 2 weeks in cycles of 28 days. Progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and safety were assessed.

Results

In total, 249 patients were randomized and treated with FOLFIRI/simtuzumab 700 mg (n = 84), FOLFIRI/simtuzumab 200 mg (n = 85), and FOLFIRI/placebo (n = 80). After a median follow-up of 5.1, 3.8, and 5.5 months, respectively, median PFS for each of the respective treatment groups was 5.5 months (adjusted HR [95% CI], p value versus placebo; 1.32 [0.92, 1.89]; p = .10), 5.4 months (1.45 [1.01, 2.06]; p = .04), and 5.8 months. Median OS was 11.4 months (1.23 [0.80, 1.91]; p = .25), 10.5 months (1.50 [0.98, 2.30]; p = .06), and 16.3 months, respectively. ORR was 11.9%, 5.9%, and 10%, respectively. Simtuzumab was tolerable in metastatic KRAS mutant CRC patients.

Conclusion

The addition of simtuzumab to FOLFIRI did not improve clinical outcomes in patients with metastatic KRAS mutant CRC.

Published: March 2017

Lessons Learned

The safety profile in the gemcitabine/simtuzumab group was similar to that in the gemcitabine/placebo group. The addition of simtuzumab to gemcitabine does not improve clinical outcomes in patients with metastatic pancreatic adenocarcinoma

Background

The humanized IgG4 monoclonal antibody simtuzumab inhibits the extracellular matrix-remodeling enzyme lysyl oxidase-like 2 maintaining pathological stroma in tumors.

Methods

Adult patients with metastatic pancreatic adenocarcinoma (mPaCa) were randomly assigned to receive intravenous gemcitabine, 1,000 mg/m2, in combination with 200 or 700 mg simtuzumab or placebo. Primary endpoint was progression-free survival (PFS), secondary endpoints included overall survival (OS), objective response rate (ORR), and safety.

Results

Of 240 patients, 80 were randomly assigned to gemcitabine/simtuzumab 700 mg, 79 to gemcitabine/simtuzumab 200 mg, and 81 to gemcitabine/placebo. After a median follow-up of 3.0, 1.9, and 3.4 months for gemcitabine/simtuzumab 700 mg, gemcitabine/simtuzumab 200 mg, and gemcitabine/placebo, respectively, the median PFS was 3.7 months (adjusted hazard ratio [HR], 95% confidence interval [CI], p value vs placebo: 1.09 [0.74–1.61]; p = .73), 3.5 months (1.13 [0.76–1.66], p = .61]), and 3.7 months, respectively. Median OS was 7.6 months (0.83 [0.57–1.22]; p = .28), 5.9 months (1.07 [0.73–1.55]; p = .69), and 5.7 months, respectively. ORRs were 13.9%, 14.5%, and 23.5%, respectively. Simtuzumab was well tolerated.

Conclusion

The addition of simtuzumab to gemcitabine did not improve clinical outcomes in patients with mPaCa.
Optimizing Maximum Ejecting Speed for a Gaussian Accelerator Cannon
Authors: Noormandipour Mohammad Reza , Manavi Seyed Ali Reza , Sarikhani Mahdi , Vahidi Elmira
Published: March 2017

This paper aims to find the maximum speed of an ejected steel ball from a magnetic cannon and determine its relation to other setup parameters. A magnet induces dipole moments in steel balls inside a magnetic cannon and makes them stick together along a straight line. At the moment of collision, this attraction reduces the motion of the balls in other directions. This creates a more efficient momentum transfer along the series of steel balls and consequently, a higher speed for the ejected ball. The striking ball was released from a height of 6 cm above the rail and collided with two magnets, followed by three balls. The speed was calculated using the projectile range formula. The speed was found to be a damping non-monotonic function of the number of balls after the magnet. The effective parameters were studied and the maximum velocity obtained under experimental conditions was 295±5 cm/s. Figures were made using SolidWorks software and data were analyzed using Microsoft Excel 2016 and Gnuplot software.

Published: March 2017

ResumoA proposta do III Colóquio Habitat e Cidadania: habitação no campo, nas águas e nas florestas, foi debater a questão agrária brasileira e o problema habitacional nas áreas rurais. As diferenças entre os participantes, no entanto, tornaram-se latentes. De um lado, destacava-se uma parcela do campesinato cujas posições amparavam-se na institucionalização de suas demandas, sobretudo a demanda habitacional. Por outro, os que se posicionaram a partir do rompimento com as relações institucionais que sequer chegam a comprometer a inviolabilidade da propriedade privada e a manutenção da estrutura fundiária brasileira. Este entrave coloca para nós, arquitetos e urbanistas, algumas indagações: a produção do habitat nas áreas rurais e a questão agrária brasileira seriam problemas relevantes para a arquitetura e o urbanismo? Como tornar visíveis, aos olhos da nossa área, as não cidades e seus não cidadãos? Este desafio torna-se extremamente complexo, pois a contradição entre terra e capital se configura enquanto um impasse estrutural tanto nas cidades quanto nas áreas rurais. Neste sentido, debater a questão habitacional a partir da totalidade dos processos de territorialização que têm deflagrado esta contradição pode nos dar pistas de como contribuir com a superação da conflituosa realidade que ainda persiste nas áreas rurais brasileiras.  Palavras-chave: colóquio habitat e cidadania; habitat e habitação nas áreas rurais; questão agrária; reforma agrária. AbstractThe proposal of the 3rd Colloquium Habitat and Citizenship: social housing in Brazilian rural areas was to discuss Brazilian agrarian issue and housing problem in rural areas. However, the differences between event participants were visible. On one side, one part of the peasantry exposed their positions from the institutionalization of their demands, including housing need. On the other side, we witnessed those who highlighted the rupture with the governments dependence – who have been disinterested in confronting inviolability of private property and the maintenance of the Brazilian land structure. This obstacle gives us, architects and urban planners, some questions: the production of habitat in rural areas and the agrarian issue would be relevant problems to architecture and urbanism? How to make visible for our science the non-cities and their non-citizens? This challenge becomes extremely complex because the contradiction between land and capital is configured as an impasse both in cities and in different rural areas. Therefore, to discuss the housing problem from the different cases of territorialization that expose this contradiction can give us some alternatives for how to contribute to overcoming the conflictive reality that still persists in Brazilian rural areas.Keywords: colloquium habitat and citizenship; habitat and housing in rural areas; agrarian issue; land reform.

МОТИВАЦИЈА СТУДЕНАТА У НАСТАВИ ЕНГЛЕСКОГ ЈЕЗИКА КАО СТРАНОГ: УТИЦАЈИ И ПРАКТИЧНЕ ИМПЛИКАЦИЈЕ
Authors: Топалов Јагода П. Топалов
Published: March 2017

У раду се разматра мотивација у учењу енглеског језика као изборног предмета студената Филозофског факултета у Новом Саду у контексту академске успешности. Мотивација у учењу страног језика представља сложен конструкт који укључује како когнитивне, тако и афективне факторе, те утицаје конкретног контекста у коме се учење одвија. У складу са тим, истраживање на коме се овај рад заснива укључило је испитивање три стадијума студентске мотивације (предизвршни, извршни и послеизвршни стадијум) током две фазе истраживања, на узорку од осамдесет и седам (Н=87) студената. У циљу прикупљања података, током истраживања коришћена су два упитника са ставкама које су испитаници оцењивали на петостепеној Ликертовој скали. Резултати истраживања указују на везу између одређених аспеката мотивационог конструкта и успешности у учењу енглеског језика. Конкретно, резултати добијени истраживањем сведоше, као прво, о смањеном утицају предизвршне фазе мотивације у оквиру институционализованог учења енглеског језика, као друго, о директној вези измешу извршне фазе мотивације студената и оствареног успеха на тесту знања енглеског језика и, као треће, о улози послеизвршне фазе мотивације у предвиђању будућег успеха.

Authors: Shen Chien-wen , Kuo Chin-Jin , Minh Ly Pham Thi
Published: March 2017

Although educational practitioners have adopted social media to their online or mobile communities, little attention has been paid to investigate the social media messages related to online or mobile learning. The purpose of this research is to identify social media influencers and trends by mining Twitter posts related to online learning and mobile learning. We identified the influencers on Twitter by three different measures: the number of tweets posted by each user, the number of mentions by other users for each user, and the number of retweets for each user. We also analyzed the trends of online learning and mobile learning by the following perspectives: the descriptive statistics of the related tweets, the monthly and hourly line charts of the related tweets, the descriptive statistics of the related retweets, the volume trends of the most retweeted tweets, and the top 10 hashtags of the related tweets.

Published: March 2017

O Tocantins possui 28 anos de emancipação política e se caracteriza por sua diversidade linguística, fruto dos intensos fluxos migratórios de pessoas procedentes, principalmente, do Maranhão, do Piauí, da Bahia e do Pará. Dentre as cidades que receberam grandes levas migratórias destacamos Porto Nacional, Pedro Afonso e Natividade, fundadas ainda no antigo norte goiano e que se constituem como importantes polos históricos, formados tanto por pessoas autóctones quanto por migrantes procedentes de diferentes regiões. Nesse interim, e partindo do pressuposto de que as citadas cidades podem apresentar importantes aspectos variacionistas do português falado no Tocantins, o presente trabalho possuiu a finalidade de identificar e analisar os róticos, grafematicamente representado por /R/, em posição de coda silábica, nas três mencionadas cidades.  As pesquisas de campo foram realizadas junto a 24 informantes topodinâmicos e topoestáticos, distribuídos pelas variáveis sexo e idade. Analisamos um extrato de questionário contendo 25 questões coletadas pelo projeto “Atlas Linguístico Topodinâmico Topoestático do Estado do Tocantins (ALiTTETO)”.

Published: March 2017

O murici (Brysonimassp., Malpighiaceae) caracteriza-se como um fruto pequeno de coloração amarelada quando maduro com sabor exótico. Pode ser consumido na forma in natura ou processado como polpas, sucos, sorvetes e geleias. Este trabalho objetivou analisar as características físico-químicas da polpa do murici e caracterizar a estabilidade das geleias armazenadas em diferentes condições de luminosidade durante 150 dias. As variáveis analisadas foram: composição centesimal, sólidos solúveis totais (ºBrix), pH, acidez total e coloração expressa como valores de L*, a*, b*, croma e hue. Adotou-se um delineamento inteiramente casualizado com três condições ambientais (temperatura ambiente na presença de luminosidade (27ºC±2ºC), temperatura ambiente na ausência de luz (27ºC±2ºC) e temperatura refrigerada (5ºC±2ºC)) e 6 períodos de armazenamento (0, 30, 60, 90, 120 e 150 dias) em três repetições. A polpa do murici apresentou 79,46% de umidade, 0,82% de proteínas, 2,02% de fibra bruta, 1,78% de lipídios e 0,69% de cinzas. A avaliação da estabilidade das geleias mostrou que o tempo de armazenamento foi o fator decisivo nas modificações das variáveis físico-químicas. O desenvolvimento de geleia a partir do murici consiste em uma boa opção de agregação de valor ao fruto, visto que, obteve-se um alimento com características nutricionais apreciáveis.
Local Actions of Melatonin in Somatic Cells of the Testis
Authors: Frungieri Mónica Beatriz , Calandra Ricardo Saúl , Rossi Soledad Paola
Published: March 2017

Environmental darkness signal is transferred from the retina to the pineal gland triggering melatonin secretion. Melatonin influences the synthesis and release of the hypothalamic GnRH and the adenohypophyseal gonadotropin hormones and therefore, regulates testicular function in photoperiodic species. Besides the brain, direct actions of melatonin at the testicular level have also been described. Melatonin released from the pineal gland to the circulation is taken up by peripheral tissues including testes. Testicular synthesis of melatonin has also been reported. The two key somatic cell types in the testis, Leydig and Sertoli cells, express melatonergic receptors. Melatonin acts as a local modulator of the endocrine activity in Leydig cells. In Sertoli cells, melatonin influences the oxidation state and the energy metabolism, and consequently may regulate spermatogenesis. Melatonergic receptors were also described in testicular macrophages and mast cells of infertile patients. Whereas melatonin exerts anti-proliferative and anti-inflammatory effects on testicular macrophages, it provides protective effects against oxidative stress in testicular mast cells. These data pinpoints melatonin as a key player in the regulation of testicular physiology (i.e. steroidogenesis, spermatogenesis) mostly in seasonal breeders. More importantly, melatonin is also involved in the modulation of testicular inflammatory and oxidant/anti-oxidant states in patients with idiopathic infertility.

The meat consumption in Indonesia is still relatively low, thus the opportunity to increase beef cattle production (population) as a meat production is relatively high. Therefore, a study on the balance of population in Central Java was carried out in order to analyze the population balance of beef cattle in Central Java. The explorative observation study and field survey was carried out in Banyumas, Purworejo, Jepara, Boyolali regencies and Surakarta, Semarang, Pekalongan. Whereas for Province central java level we used desk study method. The results of the study show that the dynamics of livestock population is determined by fertility, mortality, buchering, input and output of the livestock in certain area. The dynamic of beef cattle in Central Java in the last ten years (1995-2004) has increased 0.91 approximately. However, the increase during 2004-2005 estimated only 0.22%. central Java’s contribution to national meat production is 12.75% with increasing on production during 1997-2004 is 6.56%. this development is higher than the population increasing (0.91%/year). The increase of beef cattle population in Pekalongan is the highest (73.50%) though its population is the lowest (285 beef cattles in 2004). The decrease population is in Semarang (-10.06%) and jepara Regency (-1.68%). Implicitly it show thet in the
period, the quantities of buchering beef cattle is over the birth level.
