OBJECTIVE To compare the accuracy of a semi-quantitative proton resonance frequency shift (PRFS) thermal mapping interface and an alternative qualitative T1 thermometry model in predicting tissue necrosis in an established routine setting of MRI-guided laser ablation in the human liver. MATERIALS AND METHODS 34 cases of PRFS-guided (GRE) laser ablation were retrospectively matched with 34 cas...

Thermal convection in a rotating cylinder near onset is investigated using direct numerical simulations of the Navier–Stokes equations with the Boussinesq approximation in a regime dominated by the Coriolis force. For thermal driving too small to support convection throughout the entire cell, convection sets in as alternating pairs of hot and cold plumes in the sidewall boundary layer, the so-c...

All vertebrates regulate body temperature within narrow limits, regardless of their physiological capabilities. When do these limits develop, and can they be modified by manipulations of the developmental thermal environment? We addressed these questions by incubating the eggs of the Madagascar ground gecko, Paroedura pictus, at three temperatures and by assessing thermoregulatory behavior in h...

Introduction: On Mars, the geomorphology of numerous surface features has been attributed to the interaction of magmatic and impact heat sources with an H 2 O-rich Martian crust/megaregolith [1-3]. In addition , geochemical analyses of soil at the Pathfinder and Viking landing sites indicate high concentrations of SO 3 and Cl [4-6], consistent with interaction between a basaltic protolith and f...

It is generally agreed that thermal injury in patients and experimental animals may be associated with a variety of immunological abnormalities (1). Burned subjects have been shown to accord prolonged survival times to skin allografts (2), and this change has been associated with a diminution of their ability to exhibit delayed hypersensitivity reactions (3). In addition, the studies of Rosenth...

A scalable laser-based timing analysis technique we call laser assisted device alteration (LADA) is introduced for the rapid isolation and analysis of defect-free performance limiting circuits in advanced flip-chip packaged microprocessors and other complex IC’s. The technique, which has been demonstrated to be widely applicable to production level as well as motherboard/system level testing, u...

A mucopolysaccharide inhibitor of Theiler's GDVII virus has been purified from intestinal tissue of adult mice. The purified material has been shown to consist chiefly of carbohydrate. Following acid hydrolysis of the inhibitor, several amino adds were found to be present. The carbohydrate components shown to be present thus far are galactose, hexosamine, N-acetylhexosamine, methylpentose, hexu...

The solar nebula sustained a strong magnetic field that may have aided planetesimal accretion and imparted the chemical remanent magnetization (CRM) observed in some carbonaceous chondrite meteorites. CRM thus provides record of early Solar System at time when parent bodies experienced aqueous alteration. However, link between recorded chondrites geophysical evolution has not been thoroughly in...

The methylsulfonylmethane (MSM) is an organosulfur compound having sulfonyl functional group. It is occurred naturally in some primitive plants and used in disease related to chronic pain, inflammation, and arthritis. This study was attempted to evaluate the impact of biofield energy treatment on the physical, thermal, and spectral properties of MSM. The study was performed in two groups viz. t...

Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) covers a wide spectral region with 14 bands from visible to the thermal infrared. The different band ranges can be capable of discriminating and mapping surface rocks and predicting pathfinder minerals (i.e. alunite, kaolinite etc.) on alteration assemblages of potential targets. The aim of this study is to compare two diffe...
