More than half of astronauts develop ophthalmic changes during long-duration spaceflight consistent with an abnormal intraocular and intracranial pressure (IOP, ICP) difference. The aim our study was to assess IOP ICP head-down tilt (HDT) the additive or attenuating effects 1% CO2 lower body negative (LBNP).In Experiment I, were measured in nine healthy subjects after 3.5 h HDT five conditions: -6°, -12°, -18° HDT, -12° CO2, -20 mmHg LBNP. In II, 16 5 min at +12°, 0°, -18°, -24°, without -40...
Introduction: We investigated the effect of postural changes on various cardiovascular parameters across gender. Twenty-eight healthy subjects (16 male, 12 female) were observed at rest (supine) and subjected to 3 interventions; head-down tilt (HDT), HDT with lower body negative pressure (HDT+ LBNP −30 mm Hg), head-up (HUT), each for 10 minutes separated by a recovery period. Methods: Measurements recorded heart rate (HR), standard deviation normal-to-normal intervals, root mean square...
The aim of this study was to determine the effect rotational axis position (RAP and thus g-gradient) during short-arm human centrifugation (SAHC) upon cardiovascular responses, cerebral perfusion g-tolerance. In 10 male female participants, min passive SAHC runs were performed with RAP above head (P1), at apex (P2), or heart level (P3), foot-level Gz 1.0 g, 1.7 g 2.4 g. We hypothesized that movement from (the conventional position) towards might reduce central hypovolaemia, limit aid...
Galanin and adrenomedullin plasma responses to head-up tilt lower body negative pressure had been studied previously. However, what extent by short-arm human centrifugation (SAHC) affects these is not known. In this study, we assessed how the application of variable gradients accelerations (Δgz) via shifting rotation axis during selected hormonal responses. Specifically, tested hypothesis, that cardiovascular modulating hormones such as galanin will be higher in non-finishers when compared...
Exposure to microgravity causes a head-ward fluid shift that current spaceflight countermeasures fail fully ameliorate. Artificial gravity (AG) through short-arm human centrifugation (SAHC) has been proposed as possible countermeasure. Whilst the responses increasing g-levels have well characterized, effects of in rotational axis position (RAP), independent g-level (at feet), are not known. We hypothesized RAP in-body rotation (IBR) at heart-level, with comparable feet, would beneficial...

We present an electrochemical advanced oxidation process (eAOP) reactor employing expanded graphite, potassium iodide (KI), and electrical current, which demonstrates exceptionally high rate of inactivation E. coli (6log reduction in viable cells) at low current density 0.6 mA/cm^2), with contact time (5 minutes) concentration KI (10 ppm). Operando X-ray fluorescence mapping is used to show the distribution iodine species reactor, operando absorption spectroscopy anodic chamber reveals...
