    The Structural Heat Intercept, Insulation, and Vibration Evaluation Rig (SHIIVER) is a large scale cryogenic fluid management (CFM) test bed designed to scale CFM technologies for inclusion on large, in-space stages. A part of the evolvable Cryogenics (eCryo) project, SHIIVER is a technology development task that is supportive of future exploration propulsion needs. Technologies developed under the eCryo Project will play a critical role in enabling increasingly longer duration in-space missions beyond Low Earth Orbit (LEO)

    Development Path for Cryogenic Insulation Systems Supporting NASA Exploration

    The currently stated exploration plan for NASA includes the possibilities ranging from short (several hour duration) upper stage missions sending astronauts towards the vicinity of the moon to multiyear missions to Mars and even making and liquefying propellant on the surface of Mars. As such, NASA has developed a plan to develop multilayer insulation (MLI) at a level it can be engineered for large space craft and upper stage mission durations between several hours to several days. The Evolvable Cryogenics project has been investigating design details related to the design of large MLI blankets for in-space application. Basic MLI performance for large upper stages is scheduled to be demonstrated in 2018 on the Evolvable Cryogenics projects Structural Heat Intercept, Insulation, and Vibration Evaluation Rig (SHIIVER). Different paths are being pursued for Mars Surface applications and these concepts are much less defined and still being traded

    Genomic Insights Into The Ixodes scapularis Tick Vector Of Lyme Disease

    Ticks transmit more pathogens to humans and animals than any other arthropod. We describe the 2.1 Gbp nuclear genome of the tick, Ixodes scapularis (Say), which vectors pathogens that cause Lyme disease, human granulocytic anaplasmosis, babesiosis and other diseases. The large genome reflects accumulation of repetitive DNA, new lineages of retrotransposons, and gene architecture patterns resembling ancient metazoans rather than pancrustaceans. Annotation of scaffolds representing B57% of the genome, reveals 20,486 protein-coding genes and expansions of gene families associated with tick–host interactions. We report insights from genome analyses into parasitic processes unique to ticks, including host ‘questing’, prolonged feeding, cuticle synthesis, blood meal concentration, novel methods of haemoglobin digestion, haem detoxification, vitellogenesis and prolonged off-host survival. We identify proteins associated with the agent of human granulocytic anaplasmosis, an emerging disease, and the encephalitis-causing Langat virus, and a population structure correlated to life-history traits and transmission of the Lyme disease agent

    The European Society of cardiology (ESC) EURObservational Research Programme (EORP) Chronic Ischemic Cardiovascular Disease registry Long Term (CICD) aims to study the clinical profile, treatment modalities and outcomes of patients diagnosed with CICD in a contemporary environment in order to assess whether these patients at high cardiovascular risk are treated according to ESC guidelines on prevention or on stable coronary disease and to determine mid and long term outcomes and their determinants in this population
