The habitability of Mars is determined by the physical and chemical environment. The effect of low water availability, temperature, low atmospheric pressure and strong UV radiation has been extensively studied in relation to the survival of microorganisms. In addition to these stress factors, it was recently found that silicates exposed to simulated saltation in a Mars-like atmosphere can lead ...

[1] Spirit’s Mössbauer (MB) instrument determined the Fe mineralogy and oxidation state of 71 rocks and 43 soils during its exploration of the Gusev plains and the Columbia Hills (West Spur, Husband Hill, Haskin Ridge, northern Inner Basin, and Home Plate) on Mars. The plains are predominantly float rocks and soil derived from olivine basalts. Outcrops at West Spur and on Husband Hill have expe...

We present an interlaboratory comparison between full-length 16S rRNA gene sequence analysis and terminal restriction fragment length polymorphism (TRFLP) for microbial communities hosted on seafloor basaltic lavas, with the goal of evaluating how similarly these two different DNA-based methods used in two independent labs would estimate the microbial diversity of the same basalt samples. Two s...

Analyses by the Mars Exploration Rover (MER), Spirit, of Martian basalts from Gusev crater show that they are chemically very different from terrestrial basalts, being characterized in particular by high Mgand Fe-contents. To provide suitable analog basalts for the International Space Analogue Rockstore (ISAR), a collection of analog rocks and minerals for preparing in situ space missions, espe...

The main reservoir in the Dixie Valley geothermal field of Nevada is hosted in fractured Jurassic rocks within the hanging wall of the Stillwater fault. Within the Jurassic sequence, at least four major stages of alteration related to the fault system can be identified. The paragenetic sequence from oldest to youngest consists of Stage I) biotite-potassium feldspar veins, and epidote-chlorite-c...

A prospective, comparative study of a novel audio pillow with hypnosis text and relaxation music was conducted in 82 dental-implant surgery patients to relieve anxiety over a 6-month period. Visual analogue scales combined with the Aachen Dental Treatment Fear Inventory (AZI) questionnaire were used to quantify patients' subjective feelings of fear. Blood pressure, heart rate, and capillary oxy...

OBJECTIVES To assess whether clutter (comforters, blankets, pillows, toys) caused bumper deaths and provide an analysis of bumper-related incidents/injuries and their causal mechanisms. STUDY DESIGN Bumper-related deaths (January 1, 1985, to October 31, 2012) and incidents/injuries (January 1, 1990, to October 31, 2012) were identified from the US Consumer Product Safety Commission (CPSC) dat...

Positioning and seating are important for premature and young infants with tonal problems. Positioning with pillows and sandbags, the use of special handling techniques (Bobath's neural developmental treatment), as well as other specialized approaches, have not proved satisfactory in reducing tone or spasticity in these infants. We developed an adaptive seat designed to reduce extensor tone thr...
