Translocation of N-acetyl Cysteine Capped Fluorescent Quantum Dots in Plant Tissue: Confocal Imaging Studies
Authors: Das Smruti , Tharkur Jeremy , Tetard Laurene , Santra Swadeshmukul
Published: April 2015

Semiconductor fluorescent quantum dots (Qdots) are popularly used as bioimaging taggants in live cell imaging and spectroscopy. In recent years, Qdots taggants are emerging in agricultural applications. Studies are primarily focused on nanotoxicity of ultra-small size water-soluble Qdots in plant systems. Nanotoxicity is correlated with Qdot core composition and surface coating. However, Qdots with certain chemical composition and surface coating may boost plant growth. In this study, we report that N-acetyl cysteine (NAC) capped ∼3.5 nm size ZnS:Mn/ZnS Qdots (NAC-Qdot) are efficiently uptaken by the snow pea (Pisum sativum L., a model plant) vascular system, enhancing the root growth at a dose level of 80 μg/mL. Fluorescence microscopy studies confirmed localization of NAC-Qdots in the intercellular regions. Germination and growth of the snow pea seeds were found to be strongly dependent on Qdot dosage and incubation time with Qdots. Seed germination reached 100% within 48 hours of NAC-Qdot exposure. Based on our preliminary findings, it is suggested that NAC-Qdot can be used as systemic plant nutrient material for boosting the seed germination and plant growth.
First as Sociology, Then as Geography
Authors: Tse Justin
Published: April 2015

This essay reviews Steven J. Sutcliffe and Ingvild Sælid Gilhus's New Age Spiritualities: Rethinking Religion. It shows that their attempt to redefine religion through new age spiritualities is actually an attempt to impose an economically elite social geography onto religious studies as a social fact. My central argument is that this effort in turn reveals that religious studies serves as a sociological factory for liberal economic ideologies. It suggests that to mitigate this ideological work, a shift toward critical geography in religious studies is the way forward.

Published: April 2015

This study aimed to evaluate the efficiency of multiple centroids to study the adaptability of alfalfa genotypes (Medicago sativa L.). In this method, the genotypes are compared with ideotypes defined by the bissegmented regression model, according to the researcher's interest. Thus, genotype classification is carried out as determined by the objective of the researcher and the proposed recommendation strategy. Despite the great potential of the method, it needs to be evaluated under the biological context (with real data). In this context, we used data on the evaluation of dry matter production of 92 alfalfa cultivars, with 20 cuttings, from an experiment in randomized blocks with two repetitions carried out from November 2004 to June 2006. The multiple centroid method proved efficient for classifying alfalfa genotypes. Moreover, it showed no unambiguous indications and provided that ideotypes were defined according to the researcher's interest, facilitating data interpretation.
Atratividade de adultos de Chrysoperla externa (Hagen, 1861) aos compostos voláteis de coentro, endro e erva-doce (Apiaceae) em condições de laboratório
Authors: Resende André Luis Santos , Ferreira Roberta Botelho , Souza Brígida
Published: April 2015

Espécies de Apiaceae dispõem de óleos essenciais, nos quais podem ocorrer compostos voláteis, que funcionam como sinais para atração e manutenção de inimigos naturais nas áreas cultivadas. Com base nestas características, este trabalho objetivou avaliar a atratividade aos adultos do predador Chrysoperla externa. Foram utilizados folhas e caules de coentro, endro e erva-doce, coletados aos 30 e 60 dias após a semeadura. As plantas foram dispostas em olfatômetro de quatro vias (formato de "X") disponibilizando-se os odores para machos e fêmeas, virgens e acasalados, em testes de livre escolha. Ao serem liberados individualmente no interior do olfatômetro, foram cronometrados cinco minutos e contabilizado o tempo total de permanência do inseto em cada braço do aparelho. Os dados foram analisados pelo teste c², com frequência esperada de 25%. Estudou-se o rendimento de óleo essencial das três espécies de plantas, 30 e 60 dias após a semeadura, utilizando-se do método de hidrodestilação. A composição química dos óleos foi determinada por cromatografia gasosa acoplada a espectrômetro de massas. Verificou-se que adultos virgens têm preferência por plantas de coentro, enquanto os acasalados preferem plantas de erva-doce, ambas coletadas aos 30 dias. Plantas com 60 dias não proporcionaram resposta atrativa aos adultos de C. externa. O rendimento de óleo tendeu a aumentar com o desenvolvimento fenológico da planta. A composição química do óleo de coentro revelou, como componentes majoritários, o (2E)-decenal e decanal e, para erva-doce, a maior concentração foi de (E)-anetol.

Published: April 2015

Introduction To avoid the selection of submaximal efforts during the assessment of maximal inspiratory and expiratory pressures (MIP and MEP), some reproducibility criteria have been suggested. Criteria that stand out are those proposed by the American Thoracic Society (ATS) and European Respiratory Society (ERS) and by the Brazilian Thoracic Association (BTA). However, no studies were found that compared these criteria or assessed the combination of both protocols. Objectives To assess the pressure values selected and the number of maneuvers required to achieve maximum performance using the reproducibility criteria proposed by the ATS/ERS, the BTA and the present study. Materials and method 113 healthy subjects (43.04 ± 16.94 years) from both genders were assessed according to the criteria proposed by the ATS/ERS, BTA and the present study. Descriptive statistics were used for analysis, followed by ANOVA for repeated measures and post hoc LSD or by Friedman test and post hoc Wilcoxon, according to the data distribution. Results The criterion proposed by the present study resulted in a significantly higher number of maneuvers (MIP and MEP – median and 25%-75% interquartile range: 5[5-6], 4[3-5] and 3[3-4] for the present study criterion, BTA and ATS/ERS, respectively; p < 0.01) and higher pressure values (MIP – mean and 95% confidence interval: 103[91.43-103.72], 100[97.19-108.83] and 97.6[94.06-105.95]; MEP: median and 25%-75% interquartile range: 124.2[101.4-165.9], 123.3[95.4-153.8] and 118.4[95.5-152.7]; p < 0.05). Conclusion The proposed criterion resulted in the selection of pressure values closer to the individual’s maximal capacity. This new criterion should be considered in future studies concerning MIP and MEP measurements.

Authors: Pereira Olívia Santos
Published: April 2015

Introduction Chronic low back pain is conceived of as a multifactorial syndrome that results in the loss of functional capacity. It affects the quality of life of an individual and its treatment requires a comprehensive therapeutic approach. Objective The aim of this study is to assess the efficacy of the Santhiflex™ Method in the treatment of chronic low back pain, as well as its effects on functional capacity, health-related quality of life and body posture. Materials and methods 20 patients with chronic low back pain were randomly distributed into two groups of 10: an experimental group, which was treated with the Santhiflex™ Method of psychomotor postural re-education; and a control group, which was given a lecture on postural orientation after the first evaluation. Results The obtained data were analyzed using standard statistical software, SPSS-17 for Windows (SPSS, Chicago, IL, USA) and the results were expressed as absolute and relative frequencies, and median with first and third quartiles. The nonparametric Wilcoxon test was used for within-group samples. Intergroup comparison was performed using the Mann-Whitney test. A value of p < 0.05 was considered statistically significant. There were significant differences in the main factors assessed. Discussion The findings demonstrated a significant total improvement in low back pain scores in the EG, whereas there was no significant change in the CG. Conclusion The Santhiflex™ Method is effective in the treatment of low back pain and has positive effects on functional capacity and health-related quality of life.

Published: April 2015

A veiculação de fungicidas, inseticidas e reguladores de crescimento por meio da peliculização às sementes de tomate pode ser promissora no contexto da produção de mudas. No entanto, primeiramente, é necessário entender a dinâmica do revestimento com polímeros na germinação e vigor de sementes. Dessa forma, determinaram-se os efeitos da peliculização no potencial fisiológico de sementes de tomate e no crescimento de mudas. Para tanto, empregou-se o delineamento inteiramente casualizado, em esquema fatorial 2x4, sendo duas cultivares ('Santa Clara' e 'Kada Gigante') e quatro concentrações do polímero Disco AG Red L-203(r) (0, 50, 100 e 150mL kg-1 de semente), com quatro repetições. A interação entre os fatores (cultivar x concentrações de polímero) ocorreu somente para as variáveis germinação e primeira contagem. As concentrações 100 e 150mL kg-1 prejudicaram a germinação de sementes de tomate da cultivar 'Santa Clara'. A cultivar 'Kada Gigante' obteve um desempenho superior à 'Santa Clara' quanto à emergência de plântulas. O efeito da peliculização na germinação de sementes de tomate depende da cultivar utilizada. O potencial fisiológico de sementes de tomate não é alterado pelo uso de polímeros de revestimento
Evaluation of salt content in school meals
Authors: Viegas Cláudia Alexandra Colaço Lourenço , Torgal Jorge , Graça Pedro , Martins Maria do Rosário Oliveira
Published: April 2015

OBJECTIVE: High blood pressure is a major rick factor for cardiovascular disease, and it is closely associated with salt intake. Schools are considered ideal environments to promote health and proper eating habits. Therefore the objective of this study was to evaluate the amount of salt in meals served in school canteens and consumers' perceptions about salt. METHODS: Meals, including all the components (bread, soup, and main dish) were retrieved from school canteens. Salt was quantified by a portable salt meter. For food perception we constructed a questionnaire that was administered to high school students. RESULTS: A total of 798 food samples were analysed. Bread had the highest salt content with a mean of 1.35 g/100 g (SD=0.12). Salt in soups ranged from 0.72 g/100 g to 0.80 g/100 g (p=0.05) and, in main courses, from 0.71 g/100 to 0.97 g/100g (p=0.05). The salt content of school meals is high with a mean value of 2.83 to 3.82 g of salt per meal. Moreover, a high percentage of students consider meals neither salty nor bland, which shows they are used to the intensity/amount of salt consumed. CONCLUSION: The salt content of school meals is high, ranging from 2 to 5 times more than the Recommended Dietary Allowances for children, clearly exceeding the needs for this population, which may pose a health risk. Healthy choices are only possible in environments where such choices are possible. Therefore, salt reduction strategies aimed at the food industry and catering services should be implemented, with children and young people targeted as a major priority.

OBJETIVO: O presente trabalho tem como objetivo analisar a formação acadêmica e a atuação profissional de nutricionistas dos Núcleos de Apoio à Saúde da Família de Goiás. MÉTODOS: Trata-se de estudo descritivo e exploratório, de corte transversal, realizado com nutricionistas atuantes naqueles Núcleos. Para coleta de dados foi utilizado um questionário autoaplicável, com questões abertas e fechadas, elaboradas para caracterizar os nutricionistas, sua formação acadêmica e atuação profissional. RESULTADOS: Participaram da pesquisa 22 nutricionistas do sexo feminino, representando 88,0% do total. Destas, 59,1% possuíam menos de três anos de formadas; 13,6% fizeram especialização em Saúde da Família e apenas 27,3% sentiam-se capacitadas para a atuação profissional mediante reflexão sobre a realidade socioeconômica, política e cultural do território. Em relação à atuação, 80,0% foram contratadas em caráter temporário, o que pode comprometer o vínculo entre o profissional e a população. Ainda, 36,4% atuavam há menos de 1 ano; 18,2% foram capacitadas antes do início das atividades; e 59,1% sentiam-se pouco capacitadas para trabalhar nos núcleos. Apenas 9,1% das participantes discutiam sobre matriciamento nas reuniões e utilizavam referências sobre a ferramenta. O trabalho em equipe foi apontado como facilitador das ações realizadas, e o não conhecimento do papel dos Núcleos como um fator que dificulta. CONCLUSÃO: Os nutricionistas dos Núcleos possuem pouca experiência profissional, sentem-se pouco qualificados para atuar em saúde da família e apresentam dificuldades de compreensão da realidade social, pois a formação acadêmica não proporcionou segurança para atuação na área, assim como é precário o conhecimento sobre os Núcleos.

Published: April 2015

The aim of this study was to assess the efficiency of the simulated individual BLUP (BLUPIS) method in selecting genotypes within full-sib families of sugarcane in ratoon stage, through comparison with selection using the individual BLUP method. The optimal number of genotypes to be selected in the best families were established for mean stems mass, total soluble solids assay (BRIX), ton of stalks per hectare, and BRIX tons per hectare traits. Seventeen full-sib families were assessed in the Centre for Experimentation in Sugarcane, located in Oratórios, MG, Brazil. Mixed model methodology was used to predict the genotypic effects of each family and the genotypic values of each individual within family. BLUPIS method is efficient for individual selection. The optimal number of genotypes to be selected in the best family for obtaining higher efficiency of the BLUPIS method is 100 in the majority of cases.

Authors: Cristo-Araújo Michelly de , Rodrigues Doriane Picanço , Astolfi-Filho Spartaco , Clement Charles R.
Published: April 2015

The Peach palm Active Germplasm Bank has abundant genetic diversity in its holdings. Because it is a live collection, maintenance, characterization and evaluation are expensive, restricting its use. One way to promote more efficient use is to create a Core Collection, a set of accessions with at least 70% of the genetic diversity of the full collection with minimal repetition. The available geographic, molecular marker (RAPD) and morphometric information was systematized and the populations were stratified into wild and domesticated. The Core Collection consists of 10% of the entire collection: 31 accessions of landraces, 5 accessions of non-designated populations and 4 accessions of wild populations. The Core has 92% of the molecular polymorphism and 95% of the heterozygosity of the full collection, with minimal divergence between them by molecular variance. The Core is already receiving priority maintenance, which will contribute to long term conservation.

Published: April 2015

The objective of this study was to estimate genetic diversity of cotton mocó planted in Paraíba and Rio Grande do Norte using microsatellite markers, since mocó landraces are a valuable source of genetic diversity. A set of 38 accessions - 21 plants from Rio Grande do Norte and 17 from Paraiba - was analyzed using 24 pairs of cotton microsatellite primers, which amplified 20 polymorphic loci. The average inbreeding was 0.432, and was slightly higher in individuals from Paraíba than from Rio Grande do Norte. Genetic diversity (Nei´s unbiased estimator) between individuals from each state's populations had similar values (HT = 0.327 and 0.302 in Paraíba and Rio Grande do Norte, respectively), indicating that comparable variability has been maintained. Moreover, the proportion of diversity between populations was extremely low (DST = 0.007), but expressive between mesoregions (DST = 0.069). These data led us to conclude that the genetic similarities between populations are high.
The germination success of the cut seeds of Eugenia pyriformis depends on their size and origin

Published: April 2015

Seeds of Eugenia pyriformis may produce several seedlings after cutting. Both the type of cutting and the size of the seed can determine the success in obtaining new seedlings. The size of the seeds is dependent on both the number of seeds per fruit and the conditions in which seeds develop, as well as the biometric characteristics of these seeds obtained from different regions and seasons. The seeds from each origin were evaluated in length, width, thickness, water content and dry mass, as well as the average number of seeds per fruit. From one of the regions, seeds were grouped according to the number of seeds per fruit and also according to their size, and then cut into two and four parts, and then analyzed for the fragments germination. The results demonstrated the high capacity of these seed fragments to produce new seedlings, but the capability reduces with the reduction in seed size. This size depends not only on the number of seeds per fruit, but also on the region and the period of the seed production.

Authors: Pereira Welison Andrade , Pereira Sara Maria Andrade , Dias Denise Cunha Fernandes dos Santos
Published: April 2015

Physiological quality and vigor of the seeds comprise properties that determine a high level of activity and performance during germination and seedling emergence, having a direct relation with the establishment of the stand of a crop. In this context, the assessment of seedling development, including the analysis of the seed reserves mobilization are a reliable method to investigate the physiological potential of seed lots. In this preliminary study, the aim was to investigate the dynamics of seed reserves mobilization of a sample of soybean commercial cultivars. By means of the seedling length bioassay and weight of dry matter of seeds, cotyledons, hypocotyls and radicles, information on the reserves mobilization during the germination process was obtained. Data were subjected to analysis of variance and Scott and Knott test, and afterwards, phenotypic correlations between traits were obtained. The results have shown that the dry matter of seeds, reserves reduction of seeds and dry matter of seedlings are positively correlated, and thus, seeds containing more reserves may be more effective during the early development of seedlings. In contrast, reserve reduction of seeds and conversion efficiency of the seeds reserves in the dry matter of seedlings are negatively correlated.

Published: April 2015

PURPOSE: To contribute to the development of a Brazilian Portuguese language version of the vocal self-assessment questionnaire, Transsexual Voice Questionnaire: Male-to-Female (TVQ:MtF), and to evaluate the questionnaire for use in Brazil. METHODS: The research was divided into two parts: (1) translation and adaptation of the questionnaire (TVQ:MtF) and demographic form and (2) preliminary study of the psychometric properties (internal consistency and test-retest reliability) of the adapted version of the questionnaire. For the translation and adaptation, the following steps were taken: translation, reconciliation, back-translation, harmonization, and pilot test. The TVQ:MtF questionnaire and the demographic form were applied to 13 male-to-female transsexuals, aged between 21 and 47 years. The participants agreed to answer the TVQ:MtF on two occasions (test and retest), with an optimal interval of 30 days. RESULTS: Two psychometric properties were investigated: internal consistency and test-retest reliability. High levels of internal consistency (in both test (α=0.911) and retest (α=0.952) conditions) and reliability (with an average ICC=0.957 (95%CI 0.916-0.984)), were found. CONCLUSION: The TVQ:MtF is an appropriate instrument for vocal self-assessment of male-to-female transsexual patients, which can be recommended for clinical and research goals.

Published: April 2015

PURPOSE: To identify and systematize the main studies on the transition from enteral to oral feeding in preterm infants. RESEARCH STRATEGY: Articles that describe the transition from oral to enteral feeding in preterm infants were located in MEDLINE, LILACS, and SciELO databases. SELECTION CRITERIA: Original studies, with available abstract, published in the last 10 years were included. DATA ANALYSIS: Analysis of the methodology and the main results of the studies, and meta-analysis of the effects of sensory-motor-oral stimulation at the time of transition to full oral feeding and duration of hospitalization were conducted. RESULTS: Twenty-nine national and international publications were considered. Most studies were clinical trials (44.8%) and did not use rating scales to start the transition process (82.7%). In the meta-analysis, positive effect of stimulation of the sensory-motor-oral system was observed with respect to the transition time to oral diet (p=0.0000), but not in relation to the length of hospital stay (p=0.09). However, heterogeneity between studies was found both in the analysis of the transition time to full oral feeding (I2=93.98) and in the length of hospital stay (I2=82.30). CONCLUSION: The transition to oral feeding is an important moment, and various physical and clinical characteristics of preterm infants have been used to describe this process. Despite the impossibility of generalizing the results due to the heterogeneity of the studies, we have noted the importance of strategies for stimulation of sensory-motor-oral system to decrease the period of transition to full oral feeding system.

Published: April 2015

OBJECTIVE To review the frequency of and factors associated with fetal death in the Brazilian scientific literature.METHODS A systematic review of Brazilian studies on fetal deaths published between 2003 and 2013 was conducted. In total, 27 studies were analyzed; of these, 4 studies addressed the quality of data, 12 were descriptive studies, and 11 studies evaluated the factors associated with fetal death. The databases searched were PubMed and Lilacs, and data extraction and synthesis were independently performed by two or more examiners.RESULTS The level of completeness of fetal death certificates was deficient, both in the completion of variables, particularly sociodemographic variables, and in defining the underlying causes of death. Fetal deaths have decreased in Brazil; however, inequalities persist. Analysis of the causes of death indicated maternal morbidities that could be prevented and treated. The main factors associated with fetal deaths were absent or inadequate prenatal care, low education level, maternal morbidity, and adverse reproductive history.CONCLUSIONS Prenatal care should prioritize women that are most vulnerable (considering their social environment or their reproductive history and morbidities) with the aim of decreasing the fetal mortality rate in Brazil. Adequate completion of death certificates and investment in the committees that investigate fetal and infant deaths are necessary.
Defunta morte: luto, sobrevida, ressurreição
Authors: Rogozinski Jacob
Published: April 2015

Tendo como objetivo compreender o motivo derridiano da sobrevida, este artigo propõe a análise da concepção de morte que encontramos na obra de Jacques Derrida e do diálogo que ela estabelece com o pensamento ocidental, especificamente a respeito desse tema, em Hegel, Heidegger, Nietzsche etc. A discussão se concentra em duas aporias com as quais Derrida se confrontou: a aporia do relevamento[relève] e a aporia da finitude. Após examinar o lugar do pensamento derridiano da morte no âmbito da tradição filosófica, o trabalho procura mostrar que as relações de Derrida com a literatura - representada aqui pelas obras de Maurice Blanchot e Antoine Artaud - são capazes de oferecer uma espécie de resposta a essas aporias e de iluminar a visão da morte apresentada pelo filósofo francês.
Enlouquecer o texto da lei: a violência dos traços autobiográficos na literatura brasileira contemporânea
Authors: Magalhães Milena
Published: April 2015

A disseminação de traços autobiográficos na produção literária brasileira contemporânea, apesar de estudos recentes, reporta, ainda, uma série de questões que dizem respeito, muitas vezes, ao modo genérico e homogêneo do tratamento dado ao tema. Investiga-se em que sentido o pensamento de Jacques Derrida, para quem a "tentação autobiográfica" sempre foi uma forma de contaminar a "língua" da filosofia, pode contribuir para responder ao que acontece e tem lugar no presente.
Sem mais - decidir desde a loucura
Authors: Eyben Piero
Published: April 2015

Tomando a epígrafe de Kierkegaard lançada por Jacques Derrida em seu "Cogito e história da loucura", digo, de sua leitura do texto de Foucault, o presente trabalho propõe discutir o instante da decisão, mais além do enigma, como instância última, aporética e no limiar do enlutamento. Desse modo, toda interpretação convergiria a um espaçamento da escritura, ao espaçamento que rompe a clausura e institui-se desde o segredo, desde a paixão do nome, como fica evidenciado pela textualidade de Mallarmé, Artaud, Rosa e Derrida.

Authors: Vermelho Sônia Cristina , Velho Ana Paula Machado , Bertoncello Valdecir
Published: April 2015

Este artigo é resultado de pesquisa realizada entre os anos de 2011 e 2013, cujo tema foi redes sociais. O problema de pesquisa era identificar o perfil da produção bibliográfica brasileira sobre o referido tema e possibilidades para uso desse espaço na promoção da saúde. Por se tratar de pesquisa de cunho exploratório e descritivo, não foram estabelecidas hipóteses iniciais. O estudo teórico permitiu identificar relações históricas do conceito com as ciências naturais e também com estudos da antropologia e da filosofia; porém evidenciou uma contradição em relação ao conceito de rede social e à experiência individual e coletiva na sociedade atual. Numa segunda etapa, identificaram-se os grupos de pesquisa no Brasil que investigam temáticas relacionadas com as redes sociais. Sinteticamente, o resultado em relação a tais grupos mostrou que as áreas de conhecimento predominantes foram a comunicação (39,7%) e educação (33,3%). Quanto à região, houve predominâncias de grupos instalados no sudeste (44,2%) e, em termos de instituição, uma predominância da Pontifícia Universidade Católica de São Paulo (17,4%) e da Universidade de São Paulo (13,9%). Dos temas descritos em cada um dos grupos, as categorias analíticas “Questões econômicas e sociais” (9,7%) e “Transformações sociais e culturais” (9%) apresentaram significância em relação às demais, mostrando um perfil das pesquisas brasileiras com forte componente social.
An analysis of a large-scale liquid air energy storage system
Authors: Morgan Robert , Nelmes Stuart , Gibson Emma , Brett Gareth
Published: April 2015

Liquid air energy storage (LAES) is a class of thermo-electric energy storage that utilises cryogenic or liquid air as the storage medium. The system is charged using an air liquefier and energy is recovered through a Rankine cycle using the stored liquid air as the working fluid. The recovery, storage and recycling of cold thermal energy released during discharge more than double the overall energy efficiency of the cycle. The demand on a storage plant in a grid support application is expected to be irregular and intermittent in response to fluctuating supply from intermittent renewable generators. This will complicate the storage of thermal energy and will mean the energy flow rates in the thermal store will vary from cycle to cycle and the state of charge of the store will also vary. This paper presents an analysis of the LAES cycle. The material and configuration of the cold thermal store is discussed in particular with reference to scale and measures to mitigate losses due to the irregular and intermittent duty cycle. The paper concludes with capital and levelised cost analysis of a reference 20 MW/80 MWh LAES plant and a comparison of the levelised cost with other storage technologies.
Contrasting Two Facies of Muncung Granite in Lingga Regency Using Major, Trace, and Rare Earth Element Geochemistry
Authors: Irzon Ronaldo
Published: April 2015

DOI:10.17014/ijog.2.1.23-33Lingga Regency is located in the main range of the famous Southeast Asia granitic belt related to tin resources. There are two granitic units in this region: the S-type Muncung Granite and I-type Tanjungbuku Granite. XRF and ICP-MS were used to measure the major, trace, and rare earth elements of nine Muncung Granite samples. Two different patterns were identified from major data plotting on Harker variation diagram. Granitic rocks from Lingga and Selayar Islands are classified as A facies while others from Singkep Island is B facies. This paper used graphs and variation diagrams to reveal the differences of those two facies. Thus, REE correlation to SiO2, trace element spider diagram, and REE spider diagram show more contrasts correlation. However, both facies are syn-collisional and High-K calc-alkaline granites. Some identical characters with other granitic units in Peninsular Malaysia were also detected in this work.
Where have all the people gone? Enhancing global conservation using night lights and social media
Authors: Levin Noam , Kark Salit , Crandall David
Published: April 2015

Conservation prioritization at large scales is complex, combining biological, environmental, and social factors. While conservation scientists now more often aim to incorporate human‐related factors, a critical yet unquantified challenge remains: to identify which areas people use for recreation outside urban centers. To address this gap in applied ecology and conservation, we developed a novel approach for quantifying human presence beyond populated areas by combining social media “big data” and remote sensing tools. We used data from the Flickr photo‐sharing website as a surrogate for identifying spatial variation in visitation globally, and complemented this estimate with spatially explicit information on stable night lights between 2004 and 2012, used as a proxy for identifying urban and industrial centers. Natural and seminatural areas attracting visitors were defined as areas both highly photographed and non‐lit. The number of Flickr photographers within protected areas was found to be a reliable surrogate for estimating visitor numbers as confirmed by local authority censuses (r = 0.8). Half of all visitors' photos taken in protected areas originated from under 1% of all protected areas on Earth (250 of ~27 000). The most photographed protected areas globally included Yosemite and Yellowstone National Parks (USA), and the Lake and Peak Districts (UK). Factors explaining the spatial variation in protected areas Flickr photo coverage included their type (e.g., UNESCO World Heritage sites have higher visitation) and accessibility to roads and trails. Using this approach, we identified photography hotspots, which draw many visitors and are also unlit (i.e., are located outside urban centers), but currently remain largely unprotected, such as Brazil's Pantanal and Bolivia's Salar de Uyuni. The integrated big data approach developed here demonstrates the benefits of combining remote sensing sources and novel geo‐tagged and crowd‐sourced information from social media in future efforts to identify spatial conservation gaps and pressures in real time, and their spatial and temporal variation globally.

The Broken Thread of Health Promotion and Disease Prevention for Women During the Postpartum Period
Authors: Walker Lorraine O. , Murphey Christina L. , Nichols Francine
Published: April 2015

Postpartum maternal health affects maternal functional status, future pregnancy outcomes, maternal chronic disease development, and infant health. After pregnancy, however, many mothers may find that they face gaps in care related to their health and caregiving roles. Research shows that they were unprepared, uninformed, and unsupported during the postpartum period as they struggle with physical and emotional symptoms, infant caregiving, breastfeeding concerns, and lifestyle adjustments. Limited follow-up after a diagnosis of gestational hypertension or gestational diabetes and screening for postpartum depression are additional gaps in preventive and supportive care. Integrative reviews revealed modest efficacy and limitations of recent postpartum health promotion and disease prevention interventions. System, clinical, and community strategies are identified to address these gaps in women’s postpartum health services.

SDX was an exploration well drilled on a jack-up rig, which was located offshore on the west side of the Malay basin. The well was classified as an ultra high pressure high temperature (HPHT) due to 455°F (235°C) maximum formation temperature and 11,200 psi maximum formation pressure. SDX was a very important well for a major operator in the attempt to explore and evaluate the potential hydrocarbon prospects in the field.

SDX field was well known for its drilling challenges due to extreme narrow window and HPHT condition. The pore pressure ramp steeply increased at shallower depth causing narrow drilling operating window between pore pressure and fracture gradient. Thus, the well was considered as conventionally “un-drillable” and managed pressure drilling (MPD) was a necessary enabler to achieve the well objectives.

MPD was deployed to drill the last four hole sections, 12 ¼” × 14 ¾”, 8 ½” × 12 ¼”, 8 ½” × 9 ½” and 5 ¾” × 6 5/8” to mitigate the challenging wellbore issues. The drilling strategy was to use a lower mud weight (MW) in order to walk the pore pressure line and allow the use of optimum drilling flow rates. Two essential MPD procedures were implemented to safely verify drilling window. The pore pressure ramp was established by performing static flow check (SFC) and the losses limit was established by conducting dynamic formation integrity test (DFIT). Furthermore, total depth (TD) criteria for the MPD section was defined by the minimum window required to perform managed pressure cementing (MPC) for the liners.

SDX well was successfully drilled to TD after overcoming defying wellbore challenges due to narrow window, pore pressure ramp uncertainty and HPHT condition. MPD was fully utilized to drill four most critical sections. MPC was performed splendidly for 11 ¾” and 9 7/8” liners without influx or loss. The paper will further explain on how proven MPD solutions were planned and executed to drill this exploration HPHT well. MPD and MPC lessons learned were also highlighted in this paper as part of the knowledge sharing.

A common Pre salt offshore well from Santos Basin in Brazil has a water depth superior to 2000m (6500 ft) about 2000m of salt and produce from a carbonate reservoir. The Pre-salt reservoir is a major driver on future production development for Petrobras.

After several cases of severe circulation losses in the Pre-salt wells of Santos Basin, including the area of the well RJS-708, the previous drilling strategy was not proving to be reliable or effective. Loss control pills were ineffective while cement pills were time consuming and not providing satisfactory results. In this scenario arose the opportunity to apply the techniques of MPD (Managed Pressure Drilling) and MCD (Mud Cap drilling) as a contingency on the well RJS-708.

The well had prediction of fractures or caves along the carbonate reservoir with high probability of circulation losses during the drilling of the reservoir phase. The potential benefits of the MPD technique were large due to the possibility of minimizing the volume of fluid lost to the formation through the management of downhole pressure. The MCD technique was also considered as contingency plan, for a scenario of total losses because of the inexistence of a drilling window, even considering the downrole pressure management near balanced.

The work performed during 2013 included: Modification of the rig, training of the teams involved, preparation of MPD and MCD procedures for the drilling rig (First DP rig to use the system at Petrobras) and discussions of new procedures with the contractor. From the list of new procedures included the Dynamical Pore Pressure test, which proved to be a useful tool.

The results obtained with MPD technique were excellent. In order to remain inside operational window, an underbalance mud weight with management of the surface back pressure was adopted to remain in an overbalance condition in front of the reservoir. The MPD system managed to be inside an operating window of 0.25 ppg without significant losses, and a time deviation of less than 4% from the initial schedule and no severe losses were observed during the construction of the well
The development of water markets in China: progress, peril, and prospects
Authors: Moore Scott M.
Published: April 2015

This article employs the case of China to address questions concerning the proper design and implementation of Water Rights Trading (WRT) and its applicability in developing countries. The article relies on key-informant interviews and Chinese-language sources to explain the development of China's water markets to date, and to assess their future prospects for expansion. The article proceeds in three parts. First, it identifies three distinctive features of water policy in China that limit the applicability of market-based responses to water scarcity: a legacy of administrative control over water, a distinctive agricultural structure and politics, and central–local tensions and conflicts. Second, it surveys the status of current WRT projects in China, highlighting their limited scope by examining three case studies. Finally, the article identifies specific issues that must be addressed to further develop Chinese water markets. The article argues that water markets have an important but only partial role in meeting China's water resource challenges. Scholars interested in the design and implementation of water markets in developing countries should pay greater attention to such fundamental features of governance and water resource management, and the prospect of integrating market mechanisms with administrative and supply-augmentation approaches.

Published: April 2015

The pulp and paper sector has been a significant source of water pollution in China for many years. The Chinese government has made great efforts on water pollution control for the pulp and paper sector. While actively participating in various international treaties and conventions related to environmental management and pollution control in this sector, China has created a comprehensive environmental management framework, including several environmental policies, regulations and standards. This study reviews the current environmental framework for the management and control of water pollutants generated by the pulp and paper industry in China, with reference to relevant experiences. Apart from assessing the achievements that China has made, this study proposes some recommendations to further enhance water pollution control capacity and facilitate effective legal enforcement. Approaches such as improvements to environmental standards and permit systems, technical upgrading, cleaner production strategy, environmental monitoring improvements, integration of financing channels for environmental improvement, and enhancement of social responsibilities of enterprises are addressed.
Marginal value of natural water in agriculture: a study in the suburbs of Mekelle City, Ethiopia
Authors: Gezahegn Tafesse W. , Zhu Xueqin
Published: April 2015

In areas where markets for natural water are lacking, information on its marginal value can be an important tool for proper pricing to achieve efficient allocation of the resource. This article investigates the marginal value of natural water (rainwater used as a proxy) in agricultural crop production in the suburbs of Mekelle City, Ethiopia, by econometrically estimating individual value functions for three selected crops: wheat, barley, and teff (a staple food crop in Ethiopia). Results show that, on average, an additional 0.30 birr (birr = Ethiopian currency: 1 euro ≈ 23 birr) worth of output is generated for each extra cubic meter of rainwater used. This result provides the marginal value (shadow price) of water in crop production at a certain point of the water cycle. It thus provides useful policy information for efficiently pricing water resources based on full-cost recovery, implying that the current tap water prices should be increased at least by 0.30 birr/m3 if the scarcity value of natural water is to be accounted for. The marginal value of natural water turned out to be the highest in teff production, suggesting that producing this crop would be the most water-efficient decision in the area.
Adaptive Kriging surrogate model for the optimization design of a dense non-aqueous phase liquid-contaminated groundwater remediation process
Authors: Chu Haibo , Lu Wenxi
Published: April 2015

The optimization model needs to call the simulation model to calculate the response under different conditions for many times, and this is computationally expensive and time-consuming. To solve this problem, surrogate models can be used to yield insight into the functional relationship between the design variables and the responses, instead of simulation models in the optimization. In this paper, an integrated optimization method based on adaptive Kriging surrogate models was proposed and applied to the cost optimization of a surfactant enhanced aquifer remediation process for dense non-aqueous phase liquids (DNAPLs). First, the initial samples were created by Latin hypercube sampling, and then the responses corresponding to the initial samples were computed by a simulation model. The initial Kriging model was derived through these samples. Secondly, the adaptive Kriging surrogate model was proposed based on updating initial Kriging with new samples via infill sampling criteria. The results showed that it had improved the accuracy of the surrogate model, and the added samples had provided more information about the simulation model than the common samples. Even with the same number of samples, the adaptive Kriging surrogate model performed better than the common Kriging surrogate model, which was built only once. What's more, the integrated approach not only greatly reduced the computational burden, but also determined the actual optimal DNAPLs remediation strategy.
