Published: December 2018

Objectives
Fatigue is a limiting factor for sport performance. For this reason, optimal recovery after training is just as critical as the training program itself, if not more. Indeed, there is a need for strategies that can facilitate recovery after training, and one such strategy is the ingestion of supplements like melatonin (MEL). This study aimed to evaluate if MEL intake could improve recovery of athletes after an intermittent training session (ITS).

Methods
Fifteen elite female athletes (17.4 ± 0.4 years, 76.4 ± 5.6 kg, 1.76 ± 0.04 m; mean ± standard deviation) participated in two testing campaigns. During each period, they performed a battery of physical and cognitive tests before and after an ITS, as well as after ingesting MEL (6 mg tablet) or placebo in a randomized design. The ITS comprised the modified agility T-test, squat jump, counter movement jump, maximum standing ball-throw velocity test, maximum jump ball-throw velocity test, and 20-m sprint. Oral temperature (OT) and vigilance were evaluated before and after the ITS. Rating of perceived exertion (RPE), blood lactate [La], and glucose [Gl] were recorded after each ITS.

Results
Short-term performance, recovery of physical performance, and OT were not affected by MEL ingestion after the ITS. Moreover, MEL did not affect cognitive performance or RPE scores after the ITS. However, [La] and [Gl] (p < 0.05 for both) were decreased after MEL ingestion.

Conclusion
MEL has no effect on the recovery of physical performance but may affect glucose utilization and lactate metabolism during the team-handball training session.
Crack propagation in porous polymer sheets with different pore sizes
Authors: Takei Atsushi , Okumura Ko 
Published: December 2018

AbstractPhysical understanding of crack propagation is a fundamental issue in the industry. In the literature, crack velocities of polymer materials are strongly dependent on their visco-elastic properties and energy release rates. Recently, numerical and theoretical studies have proposed that structural sizes in polymers also influence on crack propagation. Here, using polymer sheets with similar visco-elastic properties but with different pore sizes, we vary explicitly the representative structural size and examine the effect of the size on crack propagation. Findings in this work help us to understand crack propagation in polymer materials and bio-inspired materials which have porous structures.

Published: December 2018

Objetivo: Analizar las dimensiones culturales del empleo y desempleo de jóvenes universitarios de Cali, Colombia.
Método: Estudio de antropología cognitiva. Se utilizaron listados libres y pile sort para identificar el contenido y la organización de las dimensiones. Participaron 80 jóvenes (40 hombres y 40 mujeres, con edad promedio de 20.5 años), seleccionados por muestreo propositivo.
Resultados: El empleo es una actividad laboral que genera satisfacción, permite contar con seguridad económica y acceso a beneficios materiales. Requiere de competencias, valores de tipo personal y contar con la oportunidad para acceder a ello. Implica esfuerzo a fin de tener crecimiento, superación, estabilidad, progreso y futuro. Puede generar frustración por falta o dificultad para alcanzar logros en el ámbito laboral así como la percepción de esclavitud por exceso de trabajo. Se le visualiza como una actividad que se desempeña en empresas o instituciones y en contacto con compañeros. El desempleo es un tiempo perdido que genera pobreza y necesidades, es producto de problemas sociales como la desigualdad, falta de oportunidades, así como por causa del sistema social. Produce situaciones delictivas e impactos comunitarios; en lo personal genera problemas, necesidades, complicaciones y la vivencia de emociones negativas. Es un desafío que lleva a destacar las responsabilidades que se tiene hacia la familia, mas no se especifica alguna alternativa de afrontamiento al mismo.
Conclusiones: los jóvenes participantes mostraron alto consenso en la forma de conceptualizar al empleo y al desempleo. Ello indica competencia cultural sobre los dominios culturales de los conceptos estudiados.

Published: December 2018

Se evaluó la variación fenotípica a través de 28 variables anatómicas y morfológicas mediante análisis discriminantes en poblaciones de Opuntia cantabrigiensis, O. leucotricha, O. rastrera, O. robusta y O. streptacantha que se encuentran separadas entre sí por distancias de entre 32 y 11O km. La altitud y la temperatura media anual no mostraron variación en el área de estudio. El análisis separa las poblaciones de O. cantabrigiensis , que es la especie con menor densidad (13 individuos ha-1), mientras que para el resto de las especies, cuyas poblaciones pueden alcanzar hasta 1,852 individuos ha', algunas poblaciones se yuxtaponen. No hay diferencias en los niveles de ploidía entre las poblaciones, a pesar de que se registraron niveles de ploidía entre diploide ( O. cantabrigiensis ) a octoploide ( O. streptacantha ). Por lo tanto, las diferencias fenotípicas entre las poblaciones parecen estar relacionadas con la densidad de individuos y no con variables ambientales, dada Ja falta de gradientes ambientales o a cambios en el nivel de ploidía de las distintas especies.

Assessing the Vibration Fatigue Life of Engine Mounted Components
Authors: Bonato Marco , Goge Philippe 
Published: December 2018

Abstract
As part of the design validation of components mounted on rotating machinery such as a car engine, it is essential to understand the environmental stress in which they operate. In the case of vibration loadings, the reliability must be verified according to accelerated tests that realistically reproduce the in-service stress. Indeed, a representative validation profile permits not only the assessment of the component durability, but also provides a reliable reference for design optimization (downsizing), reducing development cycle costs, and time scale. This paper proposes an innovative methodology to generate tailored vibration signals more representative of the real environment. First, the severity of the test is tailored to the specific engine usage profile, i.e., the time spent at each revolution per minute (RPM) for a given percentile of customer usage. Traditional signals of Power Spectrum Density (PSD) and sine sweep are developed according a fatigue damage approach (test tailoring). Then, a more representative vibration specification is obtained as a multiple-sine-on-random signal. The signal is expressed as a series of multiple sine sweeps (representing the engine harmonics) and a PSD (representing the random leftover signal). A case study applied to an engine mounted heat exchanger (a water-cooled intercooler) is presented. The generated specification is compared to the validation signals developed according to existing procedures. The results show that 1) the tailored approach decreases the risk of unnecessary over-testing and 2) the multi-swept-sine-on-random signal guarantees the best representativeness of the real environment.
AN ATTEMPT FOR THE PROTECTION OF SEXUAL DIVERSITY IN BRAZILIAN LAW
Authors: Pereira Marcos Vinicius Torres 
Published: December 2018

This article intends to talk about a democratic initiative of the Brazilian Bar Association to promote human rights and sexual diversity in Brazil. Brazil is walking up the road to protect LGBTI citizens and to legally recognize same-sex couples. The country has guaranteed many rights to homosexual couples and their children, but the lack of a specific act to rule these matters is a problem in a country whose legal system is still very dependent to legal acts and positivism. This work tries to show the state of art of homosexual couples’ rights in Brazil and how the proposal of a new statute to protect the rights of LGBTI people, in all aspects of their daily life could protect them and contribute for a democratic society.

Published: December 2018

Neste trabalho foi avaliado a influência de duas linhagens de levedura, baixa fermentação (Saflager) e alta fermentação (Safbrew), três fontes de nitrogênio (sulfato de amônio, peptona de caseína e um pool de aminoácidos, nas concentrações 5 g/L e 25 g/L, e o controle (sem adição de nitrogênio), na cinética de fermentação e na composição da cachaça. Os parâmetros da cinética de fermentação foram: pH, acidez total, teor de sólidos solúveis e o teor alcoólico, em amostras coletadas em 12, 24, 48, 72 e 96 horas de fermentação. A média de concentração final de etanol nos mostos foi de 7,7 ºGL. As amostras de cachaça foram analisadas por cromatografia a gás, sendo que os alcoóis superiores, propan-1-ol, álcool isobutílico e isoamílico tiveram comportamentos diferentes para as linhagens de leveduras de baixa fermentação e alta fermentação. A concentração de 5 g/L das fontes nitrogenadas já foi suficiente para elevar as concentrações dos alcoóis superiores nas amostras de cachaça.DOI: 2446941601012015045

Published: December 2018

Promover a recuperação de óleos em processos de fabricação ou para eliminá-los de águas residuais, pode-se adicionar um produto químico ao sistema. Entre as técnicas comuns para remover óleos, a adsorção parece ser uma das mais simples. Ao contrário, ao se desejar remover óleos de materiais sólidos a dessorção, empregando um material químico pode ser promissora. Neste trabalho, experimentos, empregando o equipamento Jar Test, foram realizados visando a remoção de óleo vegetal de materiais sólidos fracionados em tamanhos variados. Óleo de soja foi empregado para contaminar o material sólido disposto em placas de Petri, já triturado para os testes. Dois surfactantes distintos, qual seja o cocoamido propil betaina ou o lauril éter sulfosuccinato de sódio, foi dissolvido em água da rede pública para tratar o material. As análises da fase sólida foram feitas por gravimetria. Os resultados experimentais de análise da fase sólida apontam a EVA como sendo o de menor remoção de óleo dentre os testados.DOI: 2446941601022015045

Colistin sulphate is the ultimate antimicrobial choice for the treatment of multidrug resistance gram negative bacteria infections with in human. The purposes of this study were to detect the presence of colistin resistant E. coli and mcr-1 gene in broiler and to transfer the mcr-1 gene to Salmonella enteritidis ATCC 13076. A total of 54 one day old broilers were divided into three groups that consists of 18 chicks broiler per group and raised up to 40 days old. The first group was used as control. The first treatment group was given colistin sulphate 5 ìg/g feed for 40 days and broilers in second treatment group was given 80.000 IU/kg body weight for first three days. Swab cloaca samples were taken every 10 days from each broiler. At age 40 days all chickens were slaughtered and meat samples were collected. Samples of cloacal swabs, fresh and cooked meat were examined for the presence of colistin resistant E. coli and mcr-1 gene. Susceptibility to colistin sulfate was conducted by agar dilution method, and detection of mcr-1 gene was conducted using polymerase chain reaction. The results showed that no colistin resistant E. coli was detected in the control group. Colistin resistant E. coli (27.78%) and mcr-1 gene (20.00%) were detected in animals in the first treatment group, respectively. Whilst 11.11% colistin resistant E. coli and 5.56% were carriying mcr-1 gene in the second treatment group. Colistin resistant E. coli were found 5.56% from raw meat samples and 3.70% had mcr-1 gene. Transfer of mcr-1 gene from colistin resistant E. coli to Salmonella enteritidis ATCC 13076 was success. These results showed the necessity of limitation usage of colistin sulphate in food animal.

Slug Days by S. Leach

Leach, Sarah. Slug Days. Illustrated by Rebecca Bender. Pajama Press Inc., 2017.
On slug days, Lauren feels “slow and slimy." Nothing seems to go her way. Her classmates yell at her. Her teachers are short with her. She feels like she has no friends, and that no one likes her. On butterfly days, however, everything is great; Lauren makes her classmates laugh, works on special project with her mother, and gets to eat her favourite ice cream. As a young girl with Asperger Syndrome, an Autism Spectrum Disorder (ASD), who has trouble understanding social cues and coping with change, Lauren has more slug days than butterfly days.
Canadian author Sara Leach and illustrator Rebecca Bender provide invaluable insight into the daily struggles of children living with an ASD. As Lauren navigates through a regular week involving school and time at home, the reader is made aware of the difficulties she faces in effectively communicating with her parents, peers, and teachers. Often taking things literally, Lauren misunderstands directions and advice, which often gets her into trouble. At times, Lauren becomes frustrated and angry. While she recognizes the onset of such feelings, she has trouble controlling her behaviour. Without focusing on the disorder itself, this story provides for the reader a first-person perspective of a child on the spectrum. Bender’s lively illustrations complement the text, increasing comprehension for younger readers.
While there are bouts of humour throughout the book, there is a general air of sadness that follows Lauren from the beginning of the story to the end. Apart from Ms. Lagorio who helps Lauren practice conversing with others, the adults in Lauren’s world have a seemingly poor understanding of her condition, as well as her “plan” for avoiding strong emotional reactions and conflict, a reality for many children living with an ASD.
This chapter book is highly recommended for public and elementary school libraries, as well as parents and educators alike.
Highly Recommended: 4 stars out of 4Reviewer: Victoria Eke

The Pond by N. Davies
Authors: Borle Sean 
Published: December 2018

Davies, Nicola. The Pond. Illustrated by Cathy Fisher. Graffeg, 2017.
In this picture book, a half-finished garden pond, “a muddy, messy hole that filled our garden,” becomes a metaphor for a family’s grief at the death of a father, “a muddy, messy hole that filled our hearts.” The story highlights the fact that when someone dies, the family loses not only the person, but also the activities that the family did with that person. Eventually, the mother in this story gets the pond lined and it starts to come to life with tadpoles, dragonflies and a water lily, mirroring the family’s progression through their grief.
The artwork really carries the story forward, and accompanied by the simple text Nicola Davies depicts aquatic environments in a variety of ways. Her work is cinematic, capturing the movement and messiness of pond life. She uses dark colours, splatters, scribbles and fractures in lines to depict the family’s grief. Some of the images are beautiful. Her water lilies on solid black backgrounds are exceptional. The images in this book will engage all ages.
This book would be good for children coping with loss or those preparing to cope with loss and should be a part of public and school library collections.
