Chemical Constituents of Luculia pinceana in Vietnam and Evaluation of their Biological Activity
Authors: Giang Phan Minh , Huyen Le Thi , Dau Nguyen Van , Anh Duong Hong , Viet Pham Hung 
Published: February 2019

Background:
In the flora of China and Vietnam, Luculia pinceana Hook of the family
Rubiaceae is described as a medicinal plant. Prior chemical studies of L. pinceana in China isolated
iridois, glycosides of cincholic acid, and kaempferol glycosides from the stem, however, have not
been conducted with L. pinceana in Vietnam.

Methods:
The stem of L. pinceana was extracted with a mixture of 90%EtOH–H2O at room temperature
and the extract was further fractionated by using liquid-liquid extraction and repeated column-
chromatographic techniques. Spectroscopic data (IR, MS, 1D- and 2D-NMR) were used to determine
structures of isolated compounds.

Results:
Thirteen compounds were isolated and structurally determined. Oleanolic acid (2),
scopoletin (3), cleomiscosin A (4), (E)-mappianine E (5a), (Z)-mappianine E (5b), vanillic acid (6),
2-hydroxyacetophenone-4-O-β-D-glucopyranoside (7), sweroside (10), and 4-methoxyacetophenone-
2-O-β-D-glucopyranoside (11) were isolated for the first time from L. pinceana. Compounds
6, 10, 11, loganin (8), 7-ketologanin (9) were not active (IC50 > 300 µg/ml), whereas 7
showed a weak activity (IC50 268.35 µg/ml) in the DPPH (1,1-diphenylpicrazyl) radical scavenging
assay. A mixture of 5a/5b was cytotoxic against the human cancer cell line HepG2 (IC50 100.57
µg/ml) in the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay.

Conclusion:
L. pinceana in Vietnam was investigated for the first time. We isolated compounds of
varied biosynthetic origins including monoterpene indole, iridoid, coumarin, coumaro-lignoid, phytosterol,
oleanane triterpenoid, phenolic acid, and acetophenone. Nine of the thirteen compounds are
newly isolated from L. pinceana. The study determined weak scavenging activity of acetophenone
(7) in the DPPH-scavenging assay and weak cytotoxicity of a mixture of two monoterpene indoles
(5a and 5b) against HepG2 cell.

Formation of Corrosion Resistant Hard Coating of Litao3 by Anodizing in Molten Lino3
Authors: Hu Likun , Yuan Sicheng , Xie Panping , Xu Dengfeng , Peng Zhi , Xie Axi , Zheng Feng 
Published: February 2019

Background:
Lithium tantalate (LiTaO3) thin film was synthesized and in situ coated on
tantalum substrate via anodic oxidation.

Methods:
The effects of temperature, voltage and time on composition, morphology and hardness of
film were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Vickers
hardness, respectively.

Results:
Our results showed that surface hardness of all coated samples has been increased compared
with that of pure tantalum. The value of hardness was found to gradually increase with temperature,
voltage and reaction time of the coating process. Selected specimens, after coating, were immersed
into 10 wt% NaOH solution at 50oC for 96h to explore their anti-corrosion performance. Immersing
results indicated that LiTaO3 coated samples have a smaller mass loss and corrosion rate compared
to those of pure Ta substrate. Pure tantalum sample and those coated by LiTaO3 thin film were further
examined by electrochemical methods including open-circuit potential (OCP), potentiodynamic
polarization curves and electrochemical impedance spectra (EIS).

Conclusion:
We have found that samples coated with LiTaO3 thin film exhibit higher potentials and
lower corrosion current densities than those of pure tantalum substrate, according to the results and
analysis of OCP curves and potentiodynamic polarization curves. Upon anodic oxidation, samples
display higher polarization resistance with higher resistance to corrosion.
Coffee Economy in Late Colonial Netherlands East Indies: Estates and Capital, 1890–1940
Authors: Pradadimara Dias 
Published: February 2019

This paper provides an attempt to look at the coffee economy in late colonial Netherlands East Indies, by focusing on the private estates that produced coffee and on the capital-owning class who invested in these estates. Since mid-19th century there was an increasing accessibility for would-be planters to gain access to land, especially in Java and Sumatra. Attracted to the increasing, if volatile, the world price of the commodity, coffee-producing estates were established in great numbers across the archipelago, despite the threat of the coffee leaf rust plantdisease. Only the attraction to rubber planting and the economic crisis in the 1930s dampened the enthusiasm. At the same time, the individual planters and Indiesbased companies who controlled most of the coffee producing estates in the late 19th century were gradually replaced by incorporated companies both based in the Indies and in the Netherlands. The increasing flow of capital following the rubber boom in the early 20th century made the role of individual planters and Indiesbased companies declined further.
Intervenciones para depresión en jóvenes: de la reducción de síntomas al bienestar y funcionamiento óptimo
Authors: Freire Teresa , Correia Teixeira. Ana Maria , Silva Eliana , P. Matias Gabriela 
Published: February 2019

La depresión es un problema de salud pública importante en niños y adolescentes, lo que hace que identificar e implementar intervenciones efectivas para su tratamiento sea de creciente interés. Por lo tanto, el objetivo principal de este artículo es discutir teóricamente diferentes intervenciones psicológicas para la depresión. En particular, las que se abordan la psicopatología, la reducción de los síntomas depresivos y las nuevas intervenciones basadas en el enfoque de la psicología positiva, que se centran en el funcionamiento óptimo y el bienestar de la persona. Intervenciones con respaldo empírico para los niños y adolescentes, como la terapia cognitivo-conductual (TCC) y la terapia interpersonal (IPT), tienen un enfoque de reducción de síntomas, lo que representa una visión incompleta de funcionamiento en la juventud. En contraste, las intervenciones basadas en la psicología positiva promueven una aproximación más equilibrada que contempla los aspectos negativos y positivos de la experiencia y tiene como objetivo mejorar el bienestar. En el artículo, se presentan y discuten intervenciones nuevas, como la Terapia del Funcionamiento Óptimo Terapia para Adolescentes, que sugieren que el enfoque de las intervenciones para los adolescentes con depresión debería integrar la reducción de síntomas y la mejora de su bienestar para lograr un funcionamiento óptimo. Ayudar a que los jóvenes sean más felices y más comprometidos en sus vidas es parte de una nueva perspectiva para la práctica de la psicología clínica.

Authors: Ruvalcaba-Romero Norma A. , Gallegos Guajardo. Julia , Villegas Guinea Diana Rocío 
Published: February 2019

Debido al impacto de la resiliencia en el desarrollo personal y social de los jóvenes, es importante concentrar esfuerzos en construir o adaptar instrumentos capaces de medir y evaluar la resiliencia con validez y confiabilidad. Sin embargo actualmente no existe un instrumento adecuado en español adaptado y validado a la población mexicana para evaluar la resiliencia en los adolescentes, lo que hace necesaria la realización de este estudio con el objetivo de validar la Escala de Resiliencia para adolescentes (READ) con una muestra de adolescentes mexicanos. En este estudio se realizó la validación del READ en una muestra de 840 adolescentes que viven en la Zona Metropolitana de Guadalajara (México). Se realiza análisis factoriales exploratorios y confirmatorios, así como la validez convergente y divergente de la escala. Se encuentran características similares a otras validaciones del instrumento, diferenciándose en la generación de un nuevo factor que es relativo a la orientación a las metas probablemente derivado de las diferencias culturales con la población en la que se desarrolló la escala originalmente. Se concluye que es una escala con propiedades adecuadas para aplicarse en el contexto mexicano. Se discuten las implicaciones.
“Nos calcanhares da dúvida”: representações sobre mulheres através dos discursos humorísticos d’ A Pilhéria
Authors: Cornélio Camila Gallindo 
Published: February 2019

O objeto de investigação trata de representações sobre mulheres na década de 1920, analisadas a partir dos discursos humorísticos veiculados nas edições, relativas ao ano de 1925, da revista recifense A Pilhéria. Objetivou-se refletir sobre os significados e as classificações atribuídas às mulheres no intuito de identificar como se estruturam e se organizam tais representações. Nesse sentido, foram consideradas as práticas, os costumes, hábitos e comportamentos assumidos pelas mulheres, que indicam uma outra forma de apresentar-se através da moda e uma penetração na esfera pública devido à ultrapassagem do universo privado do lar. Apesar dessas modificações, identifica-se a construção de representações conflituosas acerca das mulheres, misto de permanências e rupturas, bem como a utilização de sua imagem para a tematização do caos moderno vivenciado à época e a produção de humorismos – sutis ou não – a esse respeito.

“Ui-Wando Paixão”: mulheres e a música brega nas tirinhas de Sérgio Bonson
Authors: Broering Virginia , Scheibe Wolff Cristina 
Published: February 2019

Este trabalho faz parte de uma pesquisa que se propõe a debater uma relação entre humor e sexo durante a década de 1980, que identificamos como sacanagem. A sacanagem é aqui proposta como uma categoria de análise à brasileira, alternativa às categorias de obscenidade e erotismo para pensar humor e sexo a partir de subjetividades específicas do país. Como fonte para esta pesquisa analisamos as tirinhas de autoria do cartunista Sérgio Bonson, publicadas no jornal catarinense O Estado durante os anos de 1986 até 1990. Neste artigo refletimos sobre como as personagens mulheres acionam o cantor de música brega, Wando, como um símbolo sexual nestes enredos humorísticos. Ressaltando, por sua vez, questões de classe suscitadas pelo gênero musical.

ABSTRACT

Objectives:
To evaluate the effectiveness of verbal behavior modification, acetaminophen, and the combined effectiveness of verbal behavior modification along with acetaminophen on orthodontic pain.

Materials and Methods:
One hundred and forty orthodontic fixed appliance patients were randomly assigned to four groups. Group A was administered acetaminophen, group B was given verbal behavior modification, group C was administered acetaminophen as well as verbal behavior modification, and group D was placebo-controlled. A visual analog scale was used to assess pain intensity after 1 week of separator placement.

Results:
Group A had less mean pain intensity when compared to group B at 6 hours (P &lt; .001) and at 1 (P &lt; .001) and 2 (P = .002) days. Group C patients encountered less mean pain intensity when compared to group B patients at 6 hours (P &lt; .001) and at 1 (P &lt; .001), 2 (P &lt; .001), and 4 (P = .001) days. There was a statistically significant difference between groups A and C (group C experienced less pain intensity) after 6 hours (P = .004) and at day 4 (P = .009) after separator placement.

Conclusions:
Acetaminophen is the main agent of orthodontic pain reduction after separator placement, with verbal behavior serving as an adjunct to it.

Informing the power system performance envelope for pulse load operation
Authors: Mills K , Xiong J , Liu X , Venkatesh P 
Published: February 2019

Future warship power systems may be subject to pulsed loads manifesting through emergent combat systems such as directed energy weapons, associated sensors and electronic warfare equipment. The integration of combat system loads with the ship’s power system means that performance becomes intrinsically linked to combat effectiveness. Hence, understanding the capability of the power system to service such loads is vital in ensuring the operator’s ability to fight the ship. This paper describes the challenge of pulse load integration from the perspective of the power system design authority. Modelling and simulation has been employed to study the electrical response of a representative power system when subject to a range pulse load characteristics. Subsequently, the effects of pulse loading are reviewed in terms of impact upon the prime mover. It is concluded that whilst electrical supply performance can be maintained within allowable power quality limits as defined by STANAG 1008, the mechanical effects can be to the detriment of engine life, highlighting key recommendations to understand both electrical and mechanical performance envelope in design for integration.
