Bio-oil as Substitute of Phenol for Synthesis of Resol-type Phenolic Resin as Wood Adhesive
Authors: Dong Fangjia , Wang Mingcun , Wang Zhehui 
Published: December 2017

Abstract
The bio-oil from fast pyrolysis of cornstalks was used as substitute of phenol to synthesize resol resin as an ideal wood adhesive. The effects of formaldehyde/phenol (F/P) molar ratios and oil/phenol (O/P) weight ratios on rehology, thermal cure, thermal resistance and adhension of plywoods were investigated. With the increase of bio-oil used in bio-resol, the gel time of the prepared bio-oil modified resol resin (bio-resol resin) increased gradually, and the exothermic peak temperature of thermal cure shifted slightly higher. It was found that the bio-resin with bio-oil/phenol = 0.5 (weight ratio) and F/P = 1.5 (molar ratio) had the best comprehensive properties. The plywoods made with the bio-resol resins fulfilled the standards of E0 and type I plywood, implying the bio-resol resins was a new environment-friendly adhesive.
Clinical outcome in a series of pediatric patients with congenital generalized lipodystrophies treated with dietary therapy
Authors: Papendieck Laura , Araujo María B. 
Published: December 2017

Abstract

Background:
Congenital generalized lipodystrophy (CGL) produces clinical features with severe metabolic consequences. Research has focused on measuring the response to the drugs. Nevertheless, there are no studies on the response to dietary therapy. The aim of this study was to show the clinical response to early nutritional intervention to modify or reverse metabolic effects in pediatric patients with CGL.

Methods:
A retrospective study was conducted on patients with CGL followed up between January 2003 and June 2017. After diagnosis, patients were indicated a diet with a total calorie intake according to the reference daily intake (RDI), without fast sugars. Clinical feature and laboratory tests (insulin, glucose, A1C, lipid panel, liver and kidney function tests), and complementary studies (abdominal ultrasonography, echocardiogram), at the first visit and during follow-up were recorded. Statistics, version 10, was used for analysis.

Results:
Eight patients were included. The median age at the first visit was 1.1 years (range, 0.28–9.9 years) and the median time of follow-up was 3.9 years (range, 0.4–9.47 years). The median initial triglyceride level was 516 mg/dL (range, 327–3590 mg/dL) p=0.014; median low-density lipoprotein (LDL) was 157 mg/dL (range, 94–370 mg/dL) p=0.03; median glycemia was 84 mg/dL (range, 63–126 mg/dL) p=0.02; median insulin was 28.84 µUI/mL (range, 3.9–116); median homeostatic model assessment-insulin resistance (HOMA-IR) was 5.3 (range, 1.21–23.2). After 3–6 months of diet, the median percentage of triglyceride decrease was 79.5% (range, 47–97%), LDL 44% (range, 20.5–59%), glycemia 8.8% (range, 0–53.1%), insulin 67.8% (range, 0–92.8%) p=0.02 and HOMA-IR was 81.5% (range, 50–98%) p=0.05. As of the last follow-up visit, in none of the patients, liver ultrasonography or echocardiogram had deteriorated.

Conclusions:
In these pediatric patients with CGL, a diet adjusted to RDI with restriction of fast sugars led to a marked improvement in metabolic parameters.

Abstract
The uranyl mineral swamboite has been redefined to swamboite-(Nd) and its structure has been solved and refined as a commensurate structure in six-dimensional superspace. The structure is monoclinic, superspace group P21

=1/2 0 1/2. The structure was refined from 8717 reflections to a final R=0.0610. The model includes modulation both of atomic positions and displacement parameters, as well as occupancy waves. The structure is based upon uranyl-silicate sheets of uranophane topology alternating with an interlayer of partly occupied Nd3+ sites and H2O molecules. The strong (3+3) dimensional modulation of the structure originates from the distribution of the Nd-dominated sites and further accommodation of the suitable geometry within the sheets and charge distribution within the structure. The separation distances between the corresponding occupied Nd sites are rationals of the super-cell vectors corresponding to the modulation vectors of the structure. The case of swamboite-(Nd) is the first example of a modulated structure within the oxysalts of U6+.
The Y Chromosome Modulates Splicing and Sex-Biased Intron Retention Rates in Drosophila
Authors: Wang Meng , Branco Alan T , Lemos Bernardo 
Published: December 2017

Abstract
The Drosophila Y chromosome is a 40-Mb segment of mostly repetitive DNA; it harbors a handful of protein-coding genes and a disproportionate amount of satellite repeats, transposable elements, and multicopy DNA arrays. Intron retention (IR) is a type of alternative splicing (AS) event by which one or more introns remain within the mature transcript. IR recently emerged as a deliberate cellular mechanism to modulate gene expression levels and has been implicated in multiple biological processes. However, the extent of sex differences in IR and the contribution of the Y chromosome to the modulation of AS and IR rates has not been addressed. Here we showed pervasive IR in the fruit fly Drosophila melanogaster with thousands of novel IR events, hundreds of which displayed extensive sex bias. The data also revealed an unsuspected role for the Y chromosome in the modulation of AS and IR. The majority of sex-biased IR events introduced premature termination codons and the magnitude of sex bias was associated with gene expression differences between the sexes. Surprisingly, an extra Y chromosome in males (X^YY genotype) or the presence of a Y chromosome in females (X^XY genotype) significantly modulated IR and recapitulated natural differences in IR between the sexes. Our results highlight the significance of sex-biased IR in tuning sex differences and the role of the Y chromosome as a source of variable IR rates between the sexes. Modulation of splicing and IR rates across the genome represent new and unexpected outcomes of the Drosophila Y chromosome.
Variables influyentes en el miedo y el rendimiento infantil en Ceuta

Published: December 2017

The low performance in different academic areas causes an enormous preoccupation; this situation promotes the search of new formulas for teaching interventions. These fast changes cause that students must learn new abilities and capacities that let them conform to this process in continuous evolution. From this perspective, with preoccupation for the little academic achievements, the emphasis is on the enormous importance that the emotions and their suitable control for the improvement of itself could have. The objective was to reflect on the predictors of fear and the academic achievement, and the influence over each other, in children aged 6 to 12 from Ceuta City. To do so, we had 404 participants: 47.8% were boys, 52.2% girls; 68.8% were Muslims, and 31.2% Christians. As tools, we implemented the Fear Survey Schedule for Children and Adolescents-II (FSSC-II), the version that Ascensio et al. (2012) adapted to the Spanish language; we also used the children’s grades. The results showed medium-high levels on all of the research variables. The first predictor of fear was gender. Other predictors were status, performance, culture, and age. The predictors of performance were culture, fear, status, and gender. Age worked as a predictor in three factors. We have found a significant relationship between fear and performance. All this leads to consider and increase the emotional competencies as a necessary measure to improve the students’ process of learning, a situation needed in our education system.

Published: December 2017

Abstract
Continuous-flow synthesis of specific functional materials is now seen as a reliable synthesis approach that gives consistent product properties. This perspective article aims to survey recent work in some of the relevant areas and to identify new domains where flow synthesis of functional materials can be better than the conventional synthesis methods. It also emphasizes the need for developing high-throughput integrated synthesis and screening systems for almost all functional materials so that laboratory-scale recipes can be transformed into reliable manufacturing processes. New areas relevant to functional materials which have remained unexplored in flow synthesis are also highlighted.
W poszukiwaniu politycznego mechanizmu egzekucji unijnych wartości

Published: December 2017

This research paper is a critical reflection on two attempts to fulfill the lack of an effective mechanism for monitoring and enforcing the Union’s values. The first attempt was made by J. W. Müller, who proposed to add a new body to Europe’s institutional system: the Copenhagen Commission. The second attempt originated from the European Parliament, which has urged the European Commission to submit, by September 2017, a proposal for the conclusion of the Union’s Pact for democracy, the rule of law and fundamental rights, in the form of an inter-institutional agreement.It is hard to predict if Müller’s Copenhagen Commission or the EP’s Pact will end up being incorporated into the Union’s system of values enforcement. Nevertheless, both attempts stand as clear proof that existing instruments are perceived as weak, and clearly point at the lack of elements that could make these instruments more effective. These are the main observations of the study.
Transformaciones territoriales en la Amazonía: indígenas, campesinos, fronteras y colonización/ Territorial transformations in the Amazon: indigenous, peasants, borders and colonization
Authors: Guerrero Cazar Fernando 
Published: December 2017

El artículo hace un balance sobre los aspectos principales que se deducen del proceso de expansión de la frontera agrícola en la Amazonía ecuatoriana con énfasis en el nororiente en donde se desarrollan actividades de explotación petrolera desde la década de 1960. Tal proceso, al igual que la colonización, junto con el ingreso de las empresas agroindustriales y madereras tuvo como trasfondo el discurso oficial de la “Amazonía como territorio vacío”. Plantea además, el papel que ha jugado la reproducción de las economías campesinas en la expansión del capital y, consecuentemente, en la integración de tierras al mercado interno y al Estado nacional. En el artículo se advierte que gracias a los flujos de colonización y sus efectos acumulados sobre la dinámica de la población está cobrando fuerza la “urbanización” de la Amazonía. En este contexto, los pueblos indígenas, así como los asentamientos poblacionales (afectados por la contaminación ambiental petrolera) permanecen como actores subordinados y excluidos de los frutos del “desarrollo”. Por último, el trabajo presenta de manera breve los artículos que forman parte del No. 12 de la revista EUTOPÍA de FLACSO, sede Ecuador.
Abstract
This article analyses the main issues related with the expansion of the agricultural frontier in the Ecuadorian rainforest, emphasizing oil extraction impacts in the northeast region since 1960. Oil extraction, land colonization, the expansion of agro-processing and wood industries influenced the discourse of “Empty Territory Rainforest”. The article also points out the role of indigenous and peasant economies in capital expansion, as well as the integration of their land to the inner market and State ownership. Thereafter, colonization flows and their cumulative effects over the population dynamics is promoting “urbanization” of the Ecuadorian rainforest. In this context, the indigenous people, as well as human settlements, both affected by the environmental impacts of oil industry, remain as agents subordinated to and excluded from “development”. Lastly, the articles in Journal “EUTOPIA”, No. 12 edition, of FLACSO-ECUADOR are introduced.

Published: December 2017

Background: Neonatal sepsis is one of the leading causes of neonatal morbidity and mortality during the neonatal period especially in the first week of life. The objectives of this study were to determine early breastfeeding initiation (EBFI) and the incidence of neonatal sepsis in in the first week of life in Chipinge District, Zimbabwe.Methods: After obtaining approval from the ethical institutional review board and Medical research council of Zimbabwe, a total of 200 healthy term neonates were recruited into a prospective cohort study within 24 hours of birth after the mothers had given an informed consent. Mother and baby pair was followed up at day 3 and day 7 to assess presence of infection using clinical checklist and physical examination.Results: The Pearson correlation was significant at 0.01 level (2 tailed) at day 3 and day 7. The findings revealed a significant association between EBFI and neonatal sepsis in the first week of life.Conclusions: Neonatal sepsis is one of the leading causes of death during the neonatal period especially in the first week of life. Findings of the study revealed a significant Pearson correlation at 0.01 levels (2 tailed) at day 3 and day 7. Delayed initiation of breastfeeding increases the risk of neonatal sepsis and about 33 % neonatal deaths can be averted if breastfeeding is initiated within an hour of birth.

Published: December 2017

Background: Urinary tract infection (UTI) is one of the common infections occurring in children causing significant morbidity and mortality. The knowledge about the risk factors helps in the management as well as preventing the recurrence of urinary tract infection. Hence this study aims to assess the various risk factors and profile of UTI.Methods:In this prospective case control study conducted in tertiary care centre between July 2011 to August 2012, children with signs and symptoms suggestive of urinary tract infection and urine culture positive for UTI were included. Age and sex matched asymptomatic children were taken as control. Preformed questionnaire was given to each patient and the results were analysed.Results: Among the 214 cases studied, 111 boys were not circumcised constituting 86.7%. Whereas the other risk factors like recent hospitalisation, recent catheterisation, common toilet usage, cleaning perineum from back to front, constipation, usage of tight underclothing, diaper usage, worm infestation, neurological abnormality, voluntary withholding of urine, reduced water intake constitute 9.3%, 0.5%, 19.6%, 17.4%, 18.2%, 0.9%, 7.9%, 26.2%, 3.7%, 33.6% and 34.6% respectively.Conclusions: Recurrent infection was most often due to unresolved bacteriuria or persistent bacteriuria than reinfection. Signs like supra pubic tenderness and hypertension are very rare. Common organisms causing urinary tract infection in our study population are E. coli followed by Klebsiella, Proteus and Pseudomonas. The risk factors of UTI depend on socioeconomic status and cultural habits.
Study of Composition and Optical Properties of Chemically Deposited Pd-xSb2S3 Thin Films
Authors: Nwofe Patrick Akata 
Published: December 2017

The study reports on the effects of different concentration of palladium impurities on the compositional and optical properties of Palladium Doped Antimony Sulphide (Pd-xSb2S3) thin films grown by the chemical bath deposition method. The films were grown at room temperature and other deposition conditions such as the bath temperature, pH, complexing agents were kept constant. The concentration of the dopants were varied between 0.1 M to 0.3 M. The films were annealed at an annealing temperature of 200 oC for 1 hour. The films were characterised using the Rutherford Back Scattering (RBS) techniques and optical spectroscopy (transmittance versus wavelength, absorbance versus wavelength) to investigate the composition, and optical constants (optical absorption coefficient, energy band gap, and extinction coefficient) respectively. X-ray diffractometry and Scanning electron microscopy were also used to investigate the structural and morphological properties of the layers. The results show that the transmittances of the doped layers were higher compared to the as-deposited layers. The energy band gap was direct, and were found to be decreased for the doped layers, compared to the as-grown films. The values of the energy band gap were typically ≤ 2.30 eV for the former and 2.48 eV for the latter. These values strongly suggest the use of these films in optoelectronic applications especially in solar cell devices.

Published: December 2017

Nanopartículas com propriedades magnéticas podem atuar no combate oncológico por meio da hipertermia terapêutica a qual provoca a desnaturação de proteínas e, portanto, o enfraquecimento de células tumorais. A principal vantagem desta técnica é efeitos colaterais mais brandos do que os tratamentos convencionais. Objetivando uma ativação indesejada do sistema imune este trabalho propõe desenvolver uma rota para a obtenção de partículas nanométricas de poliestireno (PS) visando encapsular tais partículas. Foi utilizada uma rota livre de emulsificantes o que garantiria uma maior pureza do sistema. O material sintetizado foi analisado através microscopia eletrônica de varredura, granulometria por difração a laser, análise térmica e espectroscopia no infravermelho. Foi confirmada a obtenção de poliestireno no formato esférico com tamanho médio de partícula de 317 nm ± 58 nm adequada para o uso em sistemas biológicos

Published: December 2017

Neste trabalho discute-se sobre a experiência de seleção pública para o cargo de Secretário Municipal de Educação de Londrina, no Paraná, enfatizando a relevância de dois aspectos essenciais: o tema da alta direção pública, ainda pouco explorado pela literatura no País, e o sucesso do estabelecimento de um modelo de seleção baseado na aferição prévia das competências de gestão como insumo para subsidiar nomeações políticas de natureza discricionária. Na análise dessa iniciativa pioneira, demonstra-se o diálogo existente entre a experiência de Londrina e a literatura sobre o tema da alta direção pública, explorando três dimensões: o conceito de dirigente ou líder público, a caracterização dos espaços institucionais em que atuam e o papel das competências gerenciais como eixo central para a realização de processos de escolha desses profissionais. No trabalho também se detalham as etapas que constituíram o processo de seleção em Londrina e se indicam os atores envolvidos nesse processo. Em seguida, relacionam-se os principais avanços e desafios que caracterizam um processo seletivo dessa natureza e se oferecem recomendações orientadas a gestores públicos que almejem replicar a iniciativa. A metodologia adotada para a análise do caso foi a de observação participante, considerando o envolvimento dos autores na concepção e implantação dessa experiência. Palavras-chave: Gestão de pessoas.
