Reconstruction and appraisal of Akunu–Akoko area iron ore deposits using geological and magnetic approaches
Authors: Okpoli Cyril , Akingboye Adedibu 
Published: August 2016

Abstract
Geological mapping and magnetic methods were applied for the exploration of iron ore deposits in the Akunu–Akoko area of Southwestern Nigeria for the purpose of evaluating their geological characteristics and resource potentials. A proton magnetometer measures the vertical, horizontal and total magnetic intensities in gammas. The subsurface geology was interpreted qualitatively and quantitatively. The downward continuations and second vertical derivatives, the small-sized mineralised bodies and shallow features in the study area were mapped. The faults are trending in the following directions: NE–SW, NW–SE, N–S and E–W groups, while the iron ore mineralisation is structurally controlled by two major groups of fault trends, namely, the NE–SW and NW–SE; the N–S and E–W groups are mere occurrences that do not contribute to the structural control of the iron ore mineralisation in Akunu.
The upward continuation has a linear feature similar to the principal orientation of the regional faults, while Locations 2 and 3 have relatively high magnetic susceptibility zones; suspected to be iron ore deposits. The depths to the magnetic sources ranged from 25 m to about 250 m.
Regional turbidites and turbiditic environments developed during Neogene and Quaternary in Croatia
Authors: Malvić Tomislav 
Published: August 2016

Abstract
The Croatian Neogene and Quaternary depositional sequences preserve a record of several different depositional environments with turbidite successions. These are turbiditic systems developed during the Late Miocene in the Croatian part of the Pannonian Basin System and during the Pliocene and Pleistocene in the northern Adriatic Sea. The shape, salinity and depths of depositional areas were significantly different in these two depressional areas, but both were fed mostly with Alpine detritus. Neogene turbidites with lacustrine pelitic sedimentation formed thick heterogeneous sequences of sandstones and marls (totalling several hundreds to some thousands of metres in thickness in different depressional parts) of Upper Miocene age in Northern Croatia. By contrast, Pliocene and especially Pleistocene turbidites of the northern Adriatic were deposited in a marine environment where the total thickness of sand and clay sequences can reach up to several thousand metres. In both cases, individual sandy or sandstone turbiditic sequences (events) can reach several tens of metres in thickness. These turbidite clastic sediments are important hydrocarbon reservoirs.
Hydrogeophysical investigation of groundwater potential and aquifer vulnerability prediction in basement complex terrain – A case study from Akure, Southwestern Nigeria
Authors: Akinrinade Opeyemi J. , Adesina Rasheed B. 
Published: August 2016

Abstract
This study provides a model for the prediction of groundwater potential and vulnerability of basement aquifers in parts of Akure, Southwestern Nigeria. Hydrogeophysical surveys involving very-low-frequency electromagnetic (VLF-EM) profiling and electrical resistivity (ER) sounding, as well as evaluation of hydraulic gradient using three-point method, were carried out. Ten VLF-EM reconnaissance survey traverses, with lengths ranging from 55 m to 75 m, at 10 m station separation, and 12 vertical electrical sounding (VES) stations were occupied. Two-dimensional map of the filtered real component reveals areas of high conductivity, indicative of linear features that can serve as a reservoir or conduit for fluid flow. Interpretation of the VES results delineates three to four geoelectric units. Two aquifer zones were identified, with resistivity values in the ranges of 20 Ωm to 310 Ωm and 100 Ωm to 3,000 Ω m, respectively. Transverse resistance, longitudinal conductance, coefficient of anisotropy and hydraulic gradient have values ranging from 318.2 Ωm2 to 1,041.8 Ωm2, 0.11 mhos to 0.39 mhos, 1.04 to 1.74 and 0.017 to 0.05, respectively. The results of this study identified two prospective borehole locations and the optimum position to site the proposed septic system, based on the aquifer’s protective capacity and groundwater flow properties.

Published: August 2016

Abstract
The article discusses the application of synthesis gas from pyrolysis of plastics in petrol engine. The appropriate experimental measurements were performed on a combustion engine LGW 702 designated for micro-cogeneration unit. The power parameters, economic parameters in term of brake specific fuel consumption, and internal parameters of the engine were compared to the engine running on the reference fuel - natural gas and synthesis gas. Burning synthesis gas leads to decreased performance by about 5% and to increased mass hourly consumption by 120 %. In terms of burning, synthesis gas has similar properties as natural gas. Compared with [5] a more detailed study has been prepared on the effects of angle of spark advance on the engine torque, giving more detailed assessment of engine cycle variability and considering specification of start and end of combustion in the logarithm p-V diagram.
Comparison of the Viscous Liquids Spraying by the OIG and the Oil Configurations of an Effervescent Atomizer at Low Inlet Pressures
Authors: Mlkvik Marek , Olšiak Róbert , Smolar Marek 
Published: August 2016

Abstract
In this work we studied the influence of the fluid injection configuration (OIG: outside-in-gas, OIL: outside-in-liquid) on the internal flows and external sprays parameters. We sprayed the viscous aqueous maltodextrin solutions (μ = 60 mPa·s) at a constant inlet pressure of the gas and the gas to the liquid mass flow ratio (GLR) within the range 2.5 to 20%. We found that the fluids injection has a crucial influence on the internal flows. The internal flows patterns for the OIG atomizer were the slug flows, the internal flow of the OIL device was annular which led to the significant improvement of the spray quality: Smaller droplets, faster atomization, fewer pulsations.

Laboratory experience with the liaison analyzer in the diagnosis of Clostridium difficile-associated diarrhea
Authors: Benedek Orsolya , Podbielski Andreas , Warnke Philipp 
Published: August 2016

Background
Chemiluminescent or enzyme-linked fluorescent immunoassays are commonly used to diagnose Clostridium difficile-associated diarrhea.

Methods
The LIAISON analyzer (DiaSorin, Italy) was compared to miniVIDAS (bioMérieux, France) and, furthermore, to culture of toxigenic strains. In total, 249 native stool samples were analyzed. Sensitivities, specificities, and positive and negative predictive values were investigated. Furthermore, performance under routine conditions was assessed.

Results
The glutamate dehydrogenase chemiluminescent immunoassay (GDH-CLIA) assay revealed a high sensitivity and negative predictive value. The toxins A&B assays exhibited approximately the same low sensitivity and high specificity. Technical drawbacks experienced with the LIAISON analyzer in 48% of the analyses considerably delayed the time to the first diagnostic report and interfered with laboratory routine workflow.

Conclusion
The analytical performance of the investigated platforms should be reflected in the context of implementation into the laboratory workflow.

"MORREU MUITA GENTE POBRE. FOI UMA TRAGÉDIA!" MEMÓRIAS DA CÓLERA NO PARÁ
Authors: Beltrão Jane Felipe 
Published: August 2016

durante a recente epidemida de cólera (1991/92), o número de vítimas foi elevado e, embora os enfermos se recuperassem rapidamente, muitas vezes relutavam em deixar o hospital. Lançando um olhar ao passado, descobrir que a representação da doença, que pareciam presas a antigas estruturas, produzia uma preocupação aparentemente descabida nos dias de hoje, quando o tratamento é rápido e eficaz. Logo começaram a emegir as histórias de outrora, nas quais o narrador, não protagonista do evento, apresentava imagens terríveis da primeira epidemia de cólera, ocorrida há 144 anos. Ouvi, colecionei, cotejei e analisei as memórias que saltavam do baú de recordações dos coléricos, de seus parentes e de outros protagonistas da recente epidemia. Revisando o baú, encontrei as chaves que me permiiram passar da memória à história da cólera que, ainda hoje, atemoriza os paraenses. No trabalho, apresento os fios da trama que permitiu conhecer, a partir dos protagonista da epidemia de 1991/92, um flagelo do século XIX.

AS MULHERES JURUNA NO MOVIMENTO INDÍGENA EM ALTAMIRA NO PARÁ
Authors: Saraiva Marcia Pires 
Published: August 2016

O movimento indígena em Altamira tem como caracterísitcas predominante a presença das mulheres indígenas. Este artigo aborda a participação as índias da etnia Juruna. Essas índias, de maneira inovadora, cantam e declamam a história dos seus antepassados e de suas experiências recentes em versos de cordel. Desse modo, tem conseguido chamar a atenção para existência do grupo neste espaço. Um dos temas recente nesses versos diz respeito as águas do rio Xingu. Este não é apenas o cenário de suas histórias, mas expressa a vivência do grupo com suas andanças, ponto de morada, locais míticos, enfim o seu mundo, demonstrando o quanto a identidade Juruna está articiulada ao Xingue à suas paisagens. Desse modo, as Juruna compreendem que defender o Xingu é defender a vida.Não somos ressurgidos, somos resistentes à violência e à discriminação. O índio era privdo, a gente não podia falar. Nós não tinha voz e nen vez. A gente tinha até medo de dizer que era índio. Agora... nós estamos na democracia, estamos livres psra voar (Cândida Juruna, 60 anos, liderança citadina, 10-05-2004, depoimento).

Published: August 2016

El artículo tiene como objetivo definir y estimar los principales determinantes de las ganancias de los ambulantes propietarios-autoempleados en México. Se encontró que dentro de este grupo de ambulantes están los que buscan en el ambulantaje una vía de crecimiento, así como los que encuentran en éste un refugio al ser “excluidos” de la formalidad. En el estudio se observa que son los primeros los que tienen mejores resultados. Asimismo se aprecia las mayores ganancias entre los 20 y 23 años de experiencia, teniendo el mayor crecimiento durante los cuatro primeros años. Por su parte la escolaridad y las horas trabajadas afectan positivamente el crecimiento de las ganancias. Los varones muestran mayores ganancias que las mujeres, así como los ambulantes que tienen un líder en relación con los que no lo tienen. Finalmente se observa mejores rendimientos en los vendedores de provincia respecto a los de la ciudad de México.
Expectativas y prima por riesgo inflacionario con una medida de compensación a la inflación
Authors: Melo Velandia Luis Fernando , Granados Castro Joan Camilo 
Published: August 2016

En este documento se estima una medida de compensación inflacionaria (Break Even Inflation) usando los rendimientos de los bonos de deuda del gobierno colombiano (TES) en pesos e indizados a unidades de valor real (UVR) para el periodo comprendido entre enero de 2003 y noviembre de 2009. Esta medida se descompone en expectativas de inflación y prima por riesgo inflacionario. Las expectativas de inflación se calculan con base en la representación de estado espacio de un modelo afín de estructura a término extendido. Con objeto de mejorar los pronósticos, este modelo incorpora las expectativas de inflación a 12 meses de la encuesta mensual del Banco de la República. Los resultados muestran una tendencia a la baja tanto de las expectativas de inflación como de la prima por riesgo inflacionario. Esto puede deberse al aumento de la confianza en la política monetaria por parte de los agentes. Además, los resultados indican que a corto plazo, la compensación inflacionaria es un buen indicador de expectativas de inflación
A Community-Powered, Asset-Based Approach to Intersectoral Urban Health System Planning in Chicago
Authors: Lindau Stacy Tessler , Vickery Katherine Diaz , Choi HwaJung , Makelarski Jennifer , Matthews Amber , Davis Matthew 
Published: August 2016

Objectives. To describe, and provide a nomenclature and taxonomy for classifying, the economic sectors and functional assets that could be mobilized as partners in an intersectoral health system. Methods. MAPSCorps (Meaningful, Active, Productive Science in Service to Community) employed local youths to conduct a census of all operating assets (businesses and organizations) on the South Side of Chicago, Illinois, in 2012. We classified assets by primary function into sectors and described asset and sector distribution and density per 100 000 population. We compared empirical findings with the Institute of Medicine’s (IOM’s) conceptual representation and description of intersectoral health system partners. Results. Fifty-four youths mapped a 62-square-mile region over 6 weeks; we classified 8376 assets into 23 sectors. Sectors with the most assets were food (n = 1214; 230/100 000 population), trade services (n = 1113; 211/100 000), and religious worship (n = 974;185/100 000). Several large, health-relevant sectors (2499 assets) were identified in the region but not specified in the IOM’s representation. Governmental public health, central to the IOM concept, had no physical presence in the region. Conclusions. Local youths identified several thousand assets across a broad diversity of sectors that could partner in an intersectoral health system. Empirically informed iteration of the IOM concept will facilitate local translation and propagation.

Authors: Ngo Victoria K. , Sherbourne Cathy , Chung Bowen , Tang Lingqi , Wright Aziza L. , Whittington Yolanda , Wells Kenneth , Miranda Jeanne 
Published: August 2016

Objectives. To compare the effectiveness of a (CEP) versus a technical assistance approach (Resources for Services, or RS) to disseminate depression care for low-income ethnic minority women. Methods. We conducted secondary analyses of intervention effects for largely low-income, minority women subsample (n = 595; 45.1% Latino and 45.4% African American) in a matched, clustered, randomized control trial conducted in 2 low-resource communities in Los Angeles, California, between 2010 and 2012. Outcomes assessed included mental health, socioeconomic factors, and service use at 6- and 12-month follow-up. Results. Although we found no intervention difference for depressive symptoms, there were statistically significant effects for mental health quality of life, resiliency, homelessness risk, and financial difficulties at 6 months, as well as missed work days, self-efficacy, and care barriers at 12 months favoring CEP relative to RS. CEP increased use of outpatient substance abuse services and faith-based depression visits at 6 months. Conclusions. Engaging health care and social community programs may offer modest improvements on key functional and socioeconomic outcomes, reduce care barriers, and increase engagement in alternative depression services for low-income, predominantly ethnic minority women.

Authors: Wendel Monica L. , Benden Mark E. , Zhao Hongwei , Jeffrey Christina 
Published: August 2016

Objectives. To measure changes in body mass index (BMI) percentiles among third- and fourth-grade students in stand-biased classrooms and traditional seated classrooms in 3 Texas elementary schools. Methods. Research staff recorded the height and weight of 380 students in 24 classrooms across the 3 schools at the beginning (2011–2012) and end (2012–2013) of the 2-year study. Results. After adjustment for grade, race/ethnicity, and gender, there was a statistically significant decrease in BMI percentile in the group that used stand-biased desks for 2 consecutive years relative to the group that used standard desks during both years. Mean BMI increased by 0.1 and 0.4 kilograms per meter squared in the treatment and control groups, respectively. The between-group difference in BMI percentile change was 5.24 (SE = 2.50; P = .037). No other covariates had a statistically significant impact on BMI percentile changes. Conclusions. Changing a classroom to a stand-biased environment had a significant effect on students’ BMI percentile, indicating the need to redesign traditional classroom environments.

Objectives. To determine the effectiveness of the COMmunity of Practice And Safety Support (COMPASS) Total Worker Health intervention for home care workers. Methods. We randomized 16 clusters of workers (n = 149) to intervention or usual-practice control conditions. The 12-month intervention was scripted and peer-led, and involved education on safety, health, and well-being; goal setting and self-monitoring; and structured social support. We collected measures at baseline, 6 months, and 12 months, which included workers’ experienced community of practice (i.e., people engaged in a common activity who interact regularly for shared learning and improvement). Implementation occurred during 2013 and 2014 in Oregon. Results. In an intent-to-treat analysis, relative to control, the intervention produced significant and sustained improvements in workers’ experienced community of practice. Additional significant improvements included the use of ergonomic tools or techniques for physical work, safety communication with consumer–employers, hazard correction in homes, fruit and vegetable consumption, lost work days because of injury, high-density lipoprotein cholesterol, and grip strength. Consumer–employers’ reports of caregiver safety behaviors also significantly improved. Conclusions. COMPASS was effective for improving home care workers’ social resources and simultaneously impacted both safety and health factors.

Published: August 2016

Objectives. To assess the US packaged food industry’s progress from 2009 to 2014, when the National Salt Reduction Initiative had voluntary, category-specific sodium targets with the goal of reducing sodium in packaged and restaurant foods by 25% over 5 years. Methods. Using the National Salt Reduction Initiative Packaged Food Database, we assessed target achievement and change in sales-weighted mean sodium density in top-selling products in 61 food categories in 2009 (n = 6336), 2012 (n = 6898), and 2014 (n = 7396). Results. In 2009, when the targets were established, no categories met National Salt Reduction Initiative 2012 or 2014 targets. By 2014, 26% of categories met 2012 targets and 3% met 2014 targets. From 2009 to 2014, the sales-weighted mean sodium density declined significantly in almost half of all food categories (43%; 26/61 categories). Overall, sales-weighted mean sodium density declined significantly (by 6.8%; P < .001). Conclusions. National target setting with monitoring through a partnership of local, state, and national health organizations proved feasible, but industry progress was modest. Public Health Implications. The US Food and Drug Administration’s proposed voluntary targets will be an important step in achieving more substantial sodium reductions.
