Background and Objectives: The toddler silhouettes scales have been validated in the caucascian population in developing countries but in the African population, the use of these scales is yet to be evaluated. The aim of this study was to determine the perception of mothers on the body size of toddlers using a validated scale in an African population.

Methods: This was a cross sectional study of 241 mothers and their toddlers. Study participants were recruited from the immunization and pediatric clinics. The mothers’ perceptions of the body sizes of toddlers and their own child was determined with the use of a validated 7-scale toddler silhouette. Each mother also assessed their own child with the scale. Each child’s anthropometry was documented.

Results: Majority of the mothers were able to correctly classify the underweight (95.0%) and overweight toddler silhouettes (95.7%). However, 30% of the respondents misclassified Silhouette 6 (overweight silhouette) as normal and 48.2% of the respondents misclassified a normal silhouette as underweight. The overall maternal accuracy in assessing their toddler size was 41.1%. There was a significant relationship between maternal accuracy and the maternal educational status, tribe, and toddler size.

Conclusions and Global Health implications: Toddler silhouette scales is a quick way of assessing the body size of children and could be of significant use in the developing countries. There is a need for caregivers to accurately assess the body size of their children as this will significantly influence the food mothers will give their children and thus children’s eventual growth and development.

Key words: Toddler Silhouette • Nutritional Assessment • Child Anthropometry • Developing Countries • Childhood Obesity • Nigeria

Gathering Correlated Data in Wireless Sensor Networks Using a Heuristic Algorithm
Authors: Wang Yuexian , Lim Cheng Chew
Published: May 2018

We propose a routing scheme for data gathering and aggregation in wireless sensor networks. The scheme aims to optimise an aggregation tree in order to minimise the energy dissipation of data aggregation and transmission. A modified particle swarm optimisation algorithm is developed in the proposed scheme. In addition, the routing scheme uses a generic data aggregation model which accommodates different correlation conditions. The performance of the proposed scheme is evaluated and compared with three other existing data gathering algorithms. Simulation results show that the proposed scheme outperforms existing algorithms in terms of energy consumption and that the scheme can adapt to the change of network connectivity and data correlation conditions.
Estimation Algorithm for Low Frequency Seismic Motions Based on Extended Semblance Function
Authors: Sun Lianming
Published: May 2018

Monitoring low frequency and long period ground motions is very important for earthquake detection and alarm systems, and signal processing techniques help to investigate the mechanism of deep ground motions and earthquake occurrence by detecting effective seismic information from the seismograms. In this paper a frequency domain algorithm is presented to estimate the travel time difference of seismic waves with multi-path interferences caused by the refraction effect. The spectra of the seismograms are calculated through the fast algorithm, and the multi-path parameters as well as the difference of travel time between a reference position and the seismographic stations are given by an optimization algorithm in the frequency domain. The new approach can work under conditions of refraction interference, and improve the estimation performance by using an extended semblance function. Its effectiveness is demonstrated through some numerical examples, and it is shown that the proposed algorithm is applicable to the analysis of low frequency seismograms.

Published: May 2018

This paper proposes a new first-scan method for two-scan labeling algorithms. In the first scan, our proposed method first scans image lines three by three with a leaving line, and for foreground pixels among each three lines, assigns them provisional labels, and finds and resolves label equivalences among them. Then, it processes the leaving lines from top to bottom one by one, and for each line, assigns foreground pixels on the line provisional labels, finding and resolving label equivalences between the foreground pixels and those on the lines immediately above and below the current line. Experimental results demonstrated that our method is more efficient than conventional label-equivalence-based labeling algorithms.

Published: May 2018

Iron deficiency has become a yield‐limiting factor in many agricultural areas. This study was conducted to elucidate the relationship between physiological traits and soybean [Glycine max (L.) Merr.] tolerance in the presence of different FeEDTA concentrations. Two hydroponic experiments using prescreened Fe‐efficient (FeE) and Fe‐inefficient (FeI) soybean genotypes were performed in 2014 and 2015, respectively. Various chlorophyll fluorescence parameters, antioxidant enzyme activities, and the dry weight of the plants were determined and analyzed by canonical correlation analysis, stepwise regression, and logistic equation. The effective quantum yield of photosystem II (PSII) (PhiPSII), maximal photochemical efficiency of PSII (Fv/Fm), superoxide dismutase (SOD), and peroxidase (POD) activity of the FeE genotypes were significantly higher than those of the FeI genotypes (P < 0.05). High catalase (CAT) and POD activities could improve photoprotection and PhiPSII under Fe deficiency. High POD and CAT activities and high Fv/Fm are conducive to increasing the chlorophyll content of E genotypes, and high CAT activity and longer ∆t are also conducive to increasing dry matter accumulation in FeE genotypes under Fe deficiency. In particular, in the presence of 0.02 mM FeEDTA, FeE genotypes exhibit higher PhiPSII, electron transport rate (ETR), and Fv/Fm values as well as higher SOD, POD, and CAT activities than FeI genotypes. Moreover, FeE genotypes show greater dry matter accumulation because of the longest ∆t in the presence of 0.02 mM FeEDTA. Thus, FeE genotypes have stronger tolerance to Fe deficiency because of their higher antioxidant, photochemical, and photoprotection abilities as well as their increased dry matter accumulation resulting from their longer ∆t in the presence of 0.02 mM FeEDTA.

The maximum magnetic entropy change (−ΔSM)max and relative cooling power (RCP) values were found as 2.78 J/kgK and 142.31 J/kg under 5 T field change.
Study of using Calcium Carbide Slag to Prepare Calcium Oxide Briquettes by Molding and Calcination Processes through Taguchi Method
Authors: ALTINER Mahmut
Published: May 2018

As the disposal of calcium carbide slag (CCS) obtained a by-product during an acetylene gas process creates an environmental problem, this study aimed to use of CCS to prepare calcium oxide (CaO) briquettes for re-use in the production of calcium carbide (CaC2). The influence of binder types (phosphoric acid (H3PO4), molasses, and corn syrup), binder amount (1, 3, and 5%), briquetting pressure (20, 28, and 36 MPa), calcination temperature (800, 900, and 1000 oC), and calcination time (30, 45, and 60 min) on the strength value of CaO briquettes was investigated using the Taguchi approach. The highest compressive strength value of CaO briquettes was found to be 4.05 MPa. The stability and friability values of the final product were 92% and 8%, respectively. ANOVA analysis revealed that the contribution rate of production parameters on the strength value of CaO briquettes were as follows: (i) binder amount, (ii) binder type, (iii) briquetting pressure, (iv) calcination temperature, and (v) calcination time. The optimal production conditions were determined as follows: the amount of binder: 5%, briquetting pressure: 28 MPa, calcination temperature: 900 oC, and calcination time: 60 min. The obtained CaO briquettes provide a required strength value for re-use in the production of CaC2.

Published: May 2018

Currently, the usability of building stones is determined by direct physical and mechanical tests. Dry unit weight, water absorption by weight, post-frost weight loss, uniaxial compressive strength and post-frost uniaxial compressive strength values are compared with the limiting values as specified in TS 10449 and ASTM standards in order to be used as a building stone. This study proposes a new method that can be used to evaluate building stones to be used in construction industry by use of Vp and Vs wave velocity values gathered using a nondestructive test method. Within the scope of this study, Vp and Vs wave velocities of building stones with six different textures were measured on 144 original and weathered cube samples of 7x7x7 cm3. The results from conventional test methods were compared with the proposed nondestructive test method results and a criteria that can be adopted to current relevant standards using Vp and Vs values was proposed. It was concluded that limestones samples with Vp higher than 5000 m/s and Vs higher than 2750 m/s can be used as building stone.

The constitutional basis for religious freedom in selected countries in Europe and Latin AmericaReligion helps man keep his own identity. It enables him to participate in a common heritage. The study provides the constitutional basis for religious freedom in the individual dimension in selected countries in Europe and Latin America. The authors discuss the provisions on religious freedom enshrined in the constitutions of Italy, Spain and Portugal, as well as Argentina, Chile and Colombia.The analysis leads to the conclusion that religious freedom is a human right protected both in the constitutions of European countries as well as in the constitutions of Latin American countries.The inclusion of the provisions on religious freedom in the individual dimension in the constitutions is due to certain similarities of the system of European and Latin American. Common features of both systems is that Europe and Latin America belong to the so-called Western civilization. The legal systems of Latin American countries formed primarily on the basis of Roman law.Although the wording of the provisions on religious freedom in the individual dimension in the constitutions of Latin American countries is similar to the editorial rules of the constitution states of Europe, in practice there are other ways to implement this freedom and guarantees its protection.

Authors: Aguiar Wagner José de , Braga Ricardo Augusto Pessoa
Published: May 2018

Este artigo discute potencialidades para uma abordagem transetorial na governança ambiental em nível local, tomando por base a inserção dos conselhos gestores municipais no âmbito das políticas e práticas ambientais. Enquanto parte de uma pesquisa exploratória em andamento, este trabalho envolve a coleta e a análise das leis de criação de conselhos gestores em dois municípios do semiárido pernambucano, situados na região do Alto Capibaribe, bem como de marcos legais nacionais das políticas setoriais nas quais estes conselhos estão inseridos. Diante dos resultados apresentados e discutidos, conclui-se que estes colegiados podem funcionar como mecanismos de fortalecimento de uma governança ambiental de base transetorial, na medida em que os seus marcos legais e legislações locais incorporam a dimensão ambiental aos seus princípios, seus objetivos e suas estratégias de políticas setoriais. Para tanto, faz-se necessário a promoção de alguns movimentos necessários, como a transversalização das questões ambientais na legislação local que rege a organização e funcionamento dos conselhos, bem como a revisão dos focos de intervenção destes colegiados à luz de sua complexidade.

Published: May 2018

This study aimed to correlate sustainable development indicators with the occurrence of mosquitoes from the genus Aedes and phlebotominae sand flies, vectors of dengue fever, American visceral leishmaniasis and American tegumentary leishmaniasis, in order to establish a relationship between infestation indices and sustainability conditions in southern and northern neighborhoods of Natal, Brazil, adjacent to environmental protection zones 5 and 9, respectively. Data were obtained on Aedes aegypti and A. albopictus breeding sites and captures of phlebotominae sand flies of the genus Lutzomyia in the study area between 2006 and 2008, from the Center of Zoonosis Control of the Municipal Health Secretariat, and correlated with environmental and social indicators. Factorial analysis was applied to transform these indicators into a sustainability index for each neighborhood studied (Neighborhood Sustainability Index – NSI). Relating these indices with the occurrence of insect vectors at these sites shows a high positive correlation between SID and the Breteau index of A. aegypti (p=0.028) and with the index of household infestation by phlebotominae sand flies (p=0.01). This reveals a pattern allowing the association of sustainability conditions in the study areas with the occurrence of these insects. Analyses demonstrate the occurrence of a larger number of A. aegypti breeding sites and higher indices of household infestation by phlebotominae sand flies in neighborhoods with lower sustainability indices. Knowledge of the relationship between sustainable development indicators and the occurrence of zoonotic vectors may contribute to public health programs as well as to a restructuring of public policies in the study areas.

Vigna unguiculata (L.) Walp, pertence à família Fabaceae, conhecida popularmente por "feijão macassar", é uma cultura de importante destaque na economia nordestina. Este trabalho teve por objetivo estudar a biologia floral, identificar os visitantes que realizam a polinização e a influência dos mesmos na produção de suas sementes. Foram realizados estudos morfológicos da arquitetura floral, bem como da biologia floral. O comportamento dos visitantes foi observado entre 05h00min-10h00min. Para identificar a estratégia reprodutiva realizaram-se dois experimentos: A. com os tratamentos de autopolinização espontânea e polinização natural; e B. com autopolinização espontânea e polinização cruzada manual, realizando-se ainda, estudo biométrico das sementes e frutos. V. unguiculata apresenta flores zigomorfas, contém um estandarte, duas alas e uma quilha. A antese teve início às 04h30min-05h00min, entrando em senescência às 09h00min10h00min. As abelhas Xylocopa grisescens (71% das visitas) e Eulaema nigrita (21,3%), foram consideradas polinizadores efetivos. Não houve diferença significativa na produção de frutos e sementes. V. unguiculata é capaz de produzir sementes na ausência de polinizadores, porém, possui arquitetura floral que atrai visitantes, garantindo assim a variabilidade genética.

Published: May 2018

O Acesso a Justiça se transformou em dos mais importantes direitos fundamentais na contemporaneidade. Há muito o juiz deixou de ser mero reprodutor de leis e condutor passivo do instrumento processual, próprio do Estado Liberal, passando a ser um solucionador de conflitos – uma demanda hodierna capaz de manter a coesão social, bem como a estabilização das expectativas através de suas decisões. O presente estudo tem como objetivo conhecer a ideologia dos magistrados a partir da análise de discurso crítica de sentenças em processos de natureza ambiental. A metodologia utilizada foi a análise de discurso a partir das categorias formuladas por Fairclough (2004). A partir da análise realizada foi possível identificar que mesmo atuando em demandas de natureza semelhantes os magistrados posicionaram-se distintamente, uns apresentando mais profundamente suas ideologias e outros menos.

Published: May 2018

Este artigo tem como objetivo apresentar uma revisão de literatura sobre a técnica Análise de Constelação (AC), identificando conceitos, metodologia e estudos em que foi aplicada. A Análise de Constelação é uma técnica de pesquisa interdisciplinar e transdisciplinar, que interliga diferentes percepções e está sendo utilizada para visualizar problemas complexos de tecnologia, inovação e sustentabilidade. Foi formulada em 2004 pelo Centro de Ciência e Tecnologia da Universidade Técnica de Berlim, Alemanha. No Brasil, começou a ser utilizada em um programa de pesquisas ambientais desenvolvido na bacia hidrográfica do rio São Francisco. A AC é construída coletivamente, com a participação de especialistas e stakeholders envolvidos. Sua aplicação resulta em uma matriz gráfica formada por um emaranhado de elementos, interrelacionados denominada Constelação, cuja visualização permite um rápido entendimento da questão a ser estudada. A partir dos trabalhos revisados, constatou-se que a maioria utilizou a AC em estudos sobre energias renováveis e da gestão da água e da terra. Observa-se claramente que a técnica ainda se encontra em processo de difusão, sendo atualmente dominada por um pequeno grupo de especialistas alemães e brasileiros.

Este trabalho pretende avaliar o grau de cientificidade do ordenamento jurídico-ambiental brasileiro relativo ao conceito de animal silvestre, por meio da análise das normas sobre a proteção da fauna silvestre. Foi possível constatar que o conceito de animal silvestre contido na Lei dos Crimes Ambientais (Lei no. 9.605/1998) difere do contido nos livros científicos. Entretanto as diferenciações observadas refletem tão somente os diversos critérios de valoração da fauna, sejam eles científicos, ecológicos, culturais ou geográficos. No entanto, seja qual for a classificação adotada, ela busca refletir os objetivos específicos a serem protegidos, concluindo-se então que as normas estão cumprindo o papel de proteger a biodiversidade brasileira, desde que corretamente interpretadas.

Background

Internet interventions have been proposed to improve the accessibility and use of evidence-based psychological treatments. However, little is known about attitudes toward such treatments, which can be an important barrier to their use.

Objective

This study aimed to (1) determine attitudes toward guided internet interventions, (2) assess its acceptability compared with other internet-based formats, and (3) explore predictors of acceptance.

Methods

A convenience-sample Web-based survey (N=646) assessed attitudes toward guided internet therapies (ie, perceived usefulness and helpfulness, and advantage relative to face-to-face therapy), preferences for delivery modes (ie, e-preference: guided internet interventions, unguided internet interventions, or videoconferencing psychotherapy), and potential predictors of attitudes and preferences: sociodemographics, help-seeking–related variables, attachment style, and perceived stress.

Results

Although most participants perceived internet interventions as useful or helpful (426/646, 65.9%), a few indicated their advantage relative to face-to-face therapy (56/646, 8.7%). Most participants preferred guided internet interventions (252/646, 39.0%) over videoconferencing psychotherapy (147/646, 22.8%), unguided internet interventions (124/646, 19.2%), and not using internet interventions (121/646, 18.8%; missing data: 1/646, 0.2%). Attachment avoidance and stress were related to e-preference (all P<.05). Moreover, preference for therapist-guided internet interventions was higher for individuals who were aware of internet-based treatment (χ26=12.8; P=.046).

Conclusions

Participants assessed therapist-guided internet interventions as helpful, but not equivalent to face-to-face therapies. The vast majority (523/646, 81.0%) of the participants were potentially willing to use internet-based approaches. In lieu of providing patients with only one specific low-intensity treatment, implementation concepts should offer several options, including guided internet interventions, but not limited to them. Conversely, our results also indicate that efforts should focus on increasing public knowledge about internet interventions, including information about their effectiveness, to promote acceptance and uptake.

Consumers’ purchasing decisions are heavily impacted by fresh meat color, which they consider an indicator of quality in a retail setting. The objectives of this study were to evaluate the impact of light source on surface color and lipid oxidation during retail display of fresh steaks from semimembranosus (SM), a beef muscle with moderate oxidative and color stabilities. Steaks (n = 240) from the SM (n = 20) were packaged on Styrofoam trays and overwrapped with oxygen-permeable polyvinyl chloride. Steaks were then assigned to 1 of 3 lighting treatments, high UV fluorescent (HFLO), low UV fluorescent (FLO), and light emitting diode (LED) to mimic current storage conditions with a variety of industry available fluorescent bulbs, and evaluate emerging lighting conditions with LED. Steaks were removed on retail display d 1, 3, 5, and 7 for evaluation of instrumental color (L*, a*, and b* values), surface myoglobin redox forms, metmyoglobin reducing activity, and lipid oxidation. Light source influenced (P < 0.05) redness (a* values), with HFLO-displayed steaks having greatest (P < 0.05) a* values and LED-displayed steaks exhibiting lowest (P < 0.05) a* values. Surface redness decreased (P < 0.05) over retail display day. Steaks displayed in HFLO and FLO had greater (P < 0.05) oxymyoglobin percentages than those displayed under LED, indicating that LED accelerated surface discoloration compared to HFLO and FLO lights. Metmyoglobin (MMb) percentages increased over retail display, with LED-exposed steaks having greater (P < 0.05) percentages of MMb than those displayed in HFLO and FLO. By d 7 of retail display, HFLO-exposed steaks had lower (P < 0.05) MMb percentages than the steaks displayed in both FLO and LED. Lighting type did not influence (P > 0.05) lipid oxidation in SM steaks, however, lipid oxidation increased (P < 0.05) over retail display. The findings indicated that light source influenced the color stability in SM steaks during retail display and that HFLO light can minimize surface discoloration in moderate color stability beef muscles.

This study aims to determine the effect of bamboo biochar dose on the growth and yield of peanut crops. This study used a randomized block design with one factor. The tested treatments were dosage of biochar fertilizer with 4 dosage levels and one treatment without biochar dose (control), with the treatment arrangement as follows: without biochar, 4 ton ha-1, 8 ton ha-1, 12 ton ha-1, 16 ton ha-1. This treatment was repeated 3 times to obtain 15 plot experiments. The results showed that the biochar dose treatment had significant effect on all observed variables, except the variable of plant height and maximum number of leaves per plant had no significant effect. The highest yield of dry seed oven of seeds per plant was obtained in the dosage of 4 ton ha-1 biochar dose of 21.83 g, an increase of 111.81% compared with no biochar 10.33 g. Based on regression analysis, the optimum dosage of biochar is 7.50 ton ha-1, with dry weight of oven seed per plant maximum 19.03 g.

Fish cultivation business is one of the very promising business with the increasingly cheap demand of fishery products in the community. So is the case with the cultivation of Tilapia fish. Aquaculture is not spared from various obstacles and problems that often hamper fish farming is the occurrence of disease attacks. Tilapia fish Who was attacked The disease starts with by showing signs of behavioral changes. In addition to the behavior, tilapia also experience a change in color that looks very clear difference compared to fish that are still healthy. Calculation of condition factors, from the three sampling sites average fish is in poor condition indicating that most of fish in pond cultivation have decreased condition that reach 60-90%, caused by disease / phatogen factor or environmental factor not good.The results of the laboratory analysis found six (6) parasites that infect tilapia: Dactyloyrus sp, Gyrodactylus spp, Tricodina sp, Vortycella sp, Oodinium sp, and Saprolegnia sp. Water quality is less good in the cultivation are resulted in the decreased condition of fish and support well the development of various types of parasites.
