    Get PDF
    The overall objective is to develop advanced gloves for extra vehicular activity (EVA) for future human space exploration missions and generate corresponding standards by which progress may be quantitatively assessed. The glove prototypes that result from the successful completion of this technology development activity will be delivered to NASA's Human Exploration Operations Mission Directorate (HEOMD) and ultimately to be included in an integrated test with the next generation spacesuit currently under development

    Maximizing the value of Solar System data through Planetary Spatial Data Infrastructures

    Planetary spatial data returned by spacecraft, including images and higher-order products such as mosaics, controlled basemaps, and digital elevation models (DEMs), are of critical importance to NASA, its commercial partners and other space agencies. Planetary spatial data are an essential component of basic scientific research and sustained planetary exploration and operations. The Planetary Data System (PDS) is performing the essential job of archiving and serving these data, mostly in raw or calibrated form, with less support for higher-order, more ready-to-use products. However, many planetary spatial data remain not readily accessible to and/or usable by the general science user because particular skills and tools are necessary to process and interpret them from the raw initial state. There is a critical need for planetary spatial data to be more accessible and usable to researchers and stakeholders. A Planetary Spatial Data Infrastructure (PSDI) is a collection of data, tools, standards, policies, and the people that use and engage with them. A PSDI comprises an overarching support system for planetary spatial data. PSDIs (1) establish effective plans for data acquisition; (2) create and make available higher-order products; and (3) consider long-term planning for correct data acquisition, processing and serving (including funding). We recommend that Planetary Spatial Data Infrastructures be created for all bodies and key regions in the Solar System. NASA, with guidance from the planetary science community, should follow established data format standards to build foundational and framework products and use those to build and apply PDSIs to all bodies. Establishment of PSDIs is critical in the coming decade for several locations under active or imminent exploration, and for all others for future planning and current scientific analysis.Comment: 8 pages, 0 figures.

    World Measuring Living standards within cities

    This report is divided into three main chapters. In this first chapter, we explore ‘the good, the bad, and the ugly’ of survey design for urban areas. The objective is to contribute to best practice and knowledge sharing on surveying urban areas through a frank discussion of successes and failures of the pilots, drawing particular attention to challenges associated with working in urban areas. The second chapter provides detailed information on the survey methodology. This section will act as a guide on the sampling strategy and weighting of the survey that is likely to be useful for analysts that work with data. The final chapter draws on descriptive statistics from the two pilot surveys to provide a first look at the kinds of insights that can be supported by this new survey instrument. Although this is only a preliminary analysis, the descriptive statistics provided in this chapter already demonstrate the advantages of looking at cities through a more focused lens. The chapter sheds new light on the challenges of access to basic services, informality, urban mobility, and housing in Dar es Salaam and Durban

    Priming the Historian in All Planners

    Get PDF
    This article advocates bringing historical analysis methods—thinking like a historian—and primary sources into the planning classroom. It reviews recent literature on teaching history and on how the general public uses the past. It offers an introduction and guide to historical methods and provides specific teaching examples that I have tested in my planning history course. Introducing students to historical analysis methods and primary sources, in addition to livening up the delivery of historical content, can assist students to understand the importance of context for planning solutions, the complexity of planning issues, and the possibility for change that contingency brings.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

    Association of Forced Vital Capacity with the Developmental Gene <i>NCOR2</i>

    Get PDF
    Background Forced Vital Capacity (FVC) is an important predictor of all-cause mortality in the absence of chronic respiratory conditions. Epidemiological evidence highlights the role of early life factors on adult FVC, pointing to environmental exposures and genes affecting lung development as risk factors for low FVC later in life. Although highly heritable, a small number of genes have been found associated with FVC, and we aimed at identifying further genetic variants by focusing on lung development genes. Methods Per-allele effects of 24,728 SNPs in 403 genes involved in lung development were tested in 7,749 adults from three studies (NFBC1966, ECRHS, EGEA). The most significant SNP for the top 25 genes was followed-up in 46,103 adults (CHARGE and SpiroMeta consortia) and 5,062 chi

    Genome-wide association analysis identifies six new loci associated with forced vital capacity

    Forced vital capacity (FVC), a spirometric measure of pulmonary function, reflects lung volume and is used to diagnose and monitor lung diseases. We performed genome-wide association study meta-analysis of FVC in 52,253 individuals from 26 studies and followed up the top associations in 32,917 additional individuals of European ancestry. We found six new regions associated at genome-wide significance (P < 5 × 10−8) with FVC in or near EFEMP1, BMP6, MIR129-2–HSD17B12, PRDM11, WWOX and KCNJ2. Two loci previously associated with spirometric measures (GSTCD and PTCH1) were related to FVC. Newly implicated regions were followed up in samples from African-American, Korean, Chinese and Hispanic individuals. We detected transcripts for all six newly implicated genes in human lung tissue. The new loci may inform mechanisms involved in lung development and the pathogenesis of restrictive lung disease

    SARS-CoV-2 susceptibility and COVID-19 disease severity are associated with genetic variants affecting gene expression in a variety of tissues

    Variability in SARS-CoV-2 susceptibility and COVID-19 disease severity between individuals is partly due to genetic factors. Here, we identify 4 genomic loci with suggestive associations for SARS-CoV-2 susceptibility and 19 for COVID-19 disease severity. Four of these 23 loci likely have an ethnicity-specific component. Genome-wide association study (GWAS) signals in 11 loci colocalize with expression quantitative trait loci (eQTLs) associated with the expression of 20 genes in 62 tissues/cell types (range: 1:43 tissues/gene), including lung, brain, heart, muscle, and skin as well as the digestive system and immune system. We perform genetic fine mapping to compute 99% credible SNP sets, which identify 10 GWAS loci that have eight or fewer SNPs in the credible set, including three loci with one single likely causal SNP. Our study suggests that the diverse symptoms and disease severity of COVID-19 observed between individuals is associated with variants across the genome, affecting gene expression levels in a wide variety of tissue types
