The development of a low temperature storage cabinet for the preservation of viruses and other infectious agents some years ago (Horsfall, 1940) led to the use of similar solid C02 cabinets in numerous laboratories. The original cabinet has been in continuous operation for more than 11 years, and others more or less like it have been operating for almost as long. Despite the generally satisfact...
We describe a group of alloys that exhibit "super" properties, such as ultralow elastic modulus, ultrahigh strength, super elasticity, and super plasticity, at room temperature and that show Elinvar and Invar behavior. These "super" properties are attributable to a dislocation-free plastic deformation mechanism. In cold-worked alloys, this mechanism forms elastic strain fields of hierarchical s...
Platelet concentrates are universally prepared with a standard method and stored for 5 days at room temperature (20-24°C) in gentle agitation. Currently, there is a renewed interest in the possibility of storing platelet concentrates below the standard temperatures. In fact, cold platelets might be more effective in bleeding patients and have a lower risk of bacterial transmission. Inventories ...
background: chest tube removal is a painful procedure. the goal of this study was to evaluate the effect of cold application incombination with indomethacin suppository on chest tube removal pain in patients undergoing open heart surgery. materials and methods: this single-blind, double-group clinical trial was performed on 66 patients aged 18-68 years with thechest tube in pleural space. the i...
The ultrastructural effects of dark, light, and low temperature were investigated in the cone cell endings of the red-eared turtle (Pseudemys scripta elegans). Thin sections revealed that in dark-adapted retinas maintained at 22 degrees C, the neural processes which contact the cone cells at the invaginating synapses penetrated deeply into the photoreceptor endings. When dark-adapted retinas we...
It is shown that, under realistic background considerations, an improvement in cold dark matter sensitivity of several orders of magnitude is expected from a detector based on superheated liquid droplets. Such devices are totally insensitive to minimum ionizing radiation while responsive to nuclear recoils of energies ; few keV. They operate on the same principle as the bubble chamber, but offe...
We have investigated the properties of the ultracold neutron converter materials deuterium D2, oxygen O2 and heavy methane CD4 in the temperature range between 8K and room temperature. The experimental program was performed at the FUNSPIN beamline of the Swiss Spallation Neutron Source (SINQ) at Paul Scherrer Institut (PSI). In this paper the measured cold neutron total cross-sections for D2, O...
Latest results of testing the compact dual bore quadrupole and sextupole represented. Dual bore quadrupole tested in cryostat up to ~150 A feeding current generating ~1 kG/cm in each aperture. Sextupole was tested in Dewar and able to generate ~0.7 kG/cm of integrated field. Transverse size of the magnets cold masses is about 180 mm. Dual bore water cooled room temperature apertures are 54 mm i...
Dear Editors, It is convenient to use a commercial cooling device for treatment of acute athletic injuries. However, secondary injuries may develop with improper application (1). We present a patient with unusual frostbite due to cold pack. An 18-year-old woman had right quadriceps femoris muscle strain while practicing long jump. She directly applied and fixed a commercial cold pack manufactur...
Low temperature (LT) is one of the most abiotic stresses causing loss of yield in wheat (T. aestivum). Four major genes in wheat (Triticum aestivum L.) with the dominant alleles designated Vrn–A1,Vrn–B1,Vrn–D1 and Vrn4, are known to have large effects on the vernalization response, but the effects on cold hardiness are ambiguous. Poor cold tolerance has restricted winter wheat production in reg...
