Central visual field sensitivity data from microperimetry with spatially dense sampling

Microperimetry, also referred to as fundus perimetry or fundus-driven perimetry, enables simultaneous acquisition of visual sensitivity and eye movement data. We present sensitivity data collected from 60 participants with normal vision using gaze-contingent perimetry. A custom designed spatially dense test grid was used to collect data across the visual field within 13° of fixation. These data are supplemental to a study in which we demonstrated a spatial interpolation method that facilitates comparison of acquired data from any set of spatial locations to normative data and thus screening of individuals with both normal and non-foveal fixation “Methods for normative data comparison in gaze-contigent microperimetry” (Denniss and Astle, 2016) [1]

Luminescent, sorptive and antibacterial potential of bismuth-organic framework

Metal organic frameworks are formed by the three-dimensional linkage of metal cores and organic linkers. In this work, bismuth-based metal organic framework (Bi-MOF) has been synthesized by using 5-hydroxyisophthalic acid (H2HIA) as linker via hydrothermal method. The said MOF was structurally characterized by UV/Vis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), 1H NMR, energy dispersive spectroscopy (EDS), thermogravimetric analysis (TGA) and X-ray diffraction technique. This MOF showed highly porous structure with surface area 1096 m2/g as determined by BET analysis. A model batch adsorption experiment was performed to evaluate the efficiency of methylene blue (MB) dye removal from aqueous media. It was found that monolayer adsorption capacity calculated from the Langmuir isotherm was 0.6240 mg/g. Bi-MOF was also screened for its antibacterial and luminescent behavior.                     KEY WORDS: Bismuth, Metal-organic Frameworks, Luminescence, Sorption   Bull. Chem. Soc.

Socio-economic profile of young metalworkers

This paper analyses data from a research done with automobile workers in the ABC region (in the State of São Paulo), with special emphasis on those who are between 19 and 29 years of age. A comparison of their socio-economic profile was made with that of their colleagues who are thirty or over. Pointing out the heterogeneity that characterizes youth, the text shows the existing differences, not only between the younger and the older metal workers, but also between the young metal workers and other youths that took part in previous researches. The analysis shows that, to a certain extent, those working in the automobile industry are better off than that other youths in the labor market in general, and in all senses, their situation is a lot superior to that of youths who have not been absorbed by the market, either because they are unemployed, or because they are underemployed. This does not mean, however, that these young metal workers are satisfied or that they are not fearsome of the uncertainties of a globalized world.Este artigo analisa os dados de pesquisa realizada com trabalhadores da indústria automobilística na região do ABC, com destaque para aqueles em faixa etária entre 19 e 29 anos, efetuando uma comparação entre o perfil socioeconômico desses jovens metalúrgicos e o de seus colegas de trabalho com 30 anos de idade ou mais. Destacando a heterogeneidade que caracteriza a juventude, os autores mostram as diferenças existentes não só entre os trabalhadores mais jovens e os mais velhos, mas também entre os jovens metalúrgicos e aqueles investigados em pesquisas anteriores. A análise mostrou que, se em determinados aspectos a situação dos jovens trabalhadores em montadoras é melhor do que a de outros jovens inseridos no mercado de trabalho e, em todos os sentidos, superior à dos jovens que permanecem à margem do trabalho, seja como desempregados, seja como subempregados, isso não significa, contudo, que não apresentem insatisfações e temores diante das incertezas do mundo globalizado

A web-based visual analytics platform to explore smart houses energy data for stakeholders: A case study of houses in the area of Manchester

Residential sector need quick and creative solutions since rising energy consumption poses serious risks to the economy and the environment. Information about residential houses is useful for promoting community well-being, protecting the environment, and fostering economic growth. By digging into the residential houses, we can accurately identify sudden spikes in energy consumption. Energy Performance Certificates (EPCs) play a critical role in reducing wasteful energy consumption by providing precise information about a home's energy efficiency. Unfortunately, inadequate EPC evaluations and suggestions contribute to the growing demand for energy. This research presents the creation of a smart web-based visual analytics platform that utilises data from cross-sectoral data to examine the effect of various variables on current house energy performance certificates (EPCs). In addition, our study illustrates a technique for mapping stakeholder assessments before offering substantial recommendations for refurbishments. To determine which smart home criteria are most important, we apply the Criterion Importance Through Intercriterion Correlation (CRITIC) method and weight the criteria based on their correlations. Finally, we sort smart house by their Energy Performance Certificate (EPC) ratings using the COmplex PRoportional ASsessment (COPRAS) technique

The role of pre-school quality in promoting resilience in the cognitive development of young children

The study reported here investigates the role of pre-school education as a protective factor in the development of children who are at risk due to environmental and individual factors. This investigation builds upon earlier research by examining different kinds of 'quality' in early education and tests the hypothesis that pre-schools of high quality can moderate the impacts of risks upon cognitive development. Cognitive development was measured in 2857 English pre-schoolers at 36 and 58 months of age, together with 22 individual risks to children's development, and assessments were made of the quality of their pre-school provision. Multilevel Structural Equation Modelling revealed that: the global quality of pre-school can moderate the effects of familial risk (such as poverty); the relationships between staff and children can moderate the effects of child level risk (such as low birth weight); and the specific quality of curricular provision can moderate the effects of both. Policy makers need to take quality into account in their efforts to promote resilience in young 'at risk' children through early childhood services

NGOs and government partnership for health systems strengthening: A qualitative study presenting viewpoints of government, NGOs and donors in Pakistan

<p>Abstract</p> <p>Background</p> <p>Health systems are expected to serve the population needs in an effective, efficient and equitable manner. Therefore, the importance of strengthening of public, private and community health systems has been emphasized time and again. In most of the developing countries, certain weaknesses and gaps in the government health systems have been hampering the achievement of improved health outcomes. Public sector in Pakistan has been deficient in the capacity to deliver equitable and quality health services and thus has been grossly underutilized.</p> <p>Methods</p> <p>A qualitative study comprising in-depth interviews was conducted capturing the perceptions of the government functionaries, NGO representatives and donor community about the role and position of NGOs in health systems strengthening in Pakistan's context. Analysis of the data was done manually to generate nodes, sub-nodes and themes.</p> <p>Results</p> <p>Since many years, international and local non-governmental organizations (NGOs) have endeavored to fill the gaps in health service delivery, research and advocacy. NGOs have relatively performed better and achieved the results because of the flexible planning and the ability to design population based projects on health education, health promotion, social marketing, community development and advocacy. This paper captures the need and the opportunity of public private partnership in Pakistan and presents a framework for a meaningful engagement of the government and the private and nonprofit NGOs.</p> <p>Conclusion</p> <p>Involving the NGOs for health system strengthening may eventually contribute to create a healthcare system reflecting an increased efficiency, more equity and good governance in the wake of the Millennium Development Goals. Nevertheless, few questions need to be answered and pre-requisites have to be fulfilled before moving on.</p

A simple architecture with self-assembled monolayers to build immunosensors for detecting the pancreatic cancer biomarker CA19-9

Accepted ManuscriptThe challenge of the early diagnosis of pancreatic cancer in routine clinical practice requires low-cost means of detection, and this may be achieved with immunosensors based on electrical or electrochemical principles. In this paper, we report a potentially low-cost immunosensor built with interdigitated gold electrodes coated with a self-assembled monolayer and a layer of anti-CA19-9 antibodies, which is capable of detecting the pancreatic cancer biomarker CA19-9 using electrical impedance spectroscopy. Due to specific, irreversible adsorption of CA19-9 onto its corresponding antibody, according to data from polarization-modulated infrared reflection absorption spectroscopy (PM-IRRAS), the immunosensor is highly sensitive and selective. It could detect CA19-9 in commercial samples with a limit of detection of 0.68 U mL−1, in addition to distinguishing between blood serum samples from patients with different concentrations of CA19-9. Furthermore, by treating the capacitance data with information visualization methods, we were able to verify the selectivity and robustness of the immunosensor with regard to false positives, as the samples containing higher CA19-9 concentrations, including those from tumor cells, could be distinguished from those with possible interferents.CAPES, FAPESP (Grant 2013/14262-7 and 2012/15543-7), CNPq (150985/2017-7), nBioNet network and Barretos Cancer Hospital for financial supportinfo:eu-repo/semantics/publishedVersio
