A model for laser melting of carbon at high temperatures to form liquid carbon has been developed. This model is solved numerically using experimental data from laser irradiation studies in graphite consistent with a melting temperature for graphite of 4300 K. The parameters for high-temperature graphite are based on…

Intrinsic thermal clothing insulation and surface air insulation were measured on human subjects by the use of indirect calorimetry. Four male clothing ensembles (0-1-1 -8 clo) and three female clothing ensembles (0-2-1-2 clo) were investigated. Using the standing position as a reference, the influence of sitting, bic…

Abstract The crystal structure of the kaolinite: dimethylsulfoxide (DMSO) intercalate ( P 1, a = 5.187(2), b = 8.964(3), c = 11.838(4) Å, α = 91.53(1)°, β = 108.59(2), γ = 89.92(1)°) has been determined using spectroscopic and X-ray and neutron powder diffraction data. Both the X-ray and neutron powder diffraction pat…

The textural attributes of 8 different heat‐induced protein gel preparations evaluated by torsion failure testing and Instron texture profile analysis (TPA) were compared to sensory ratings by a trained texture profile panel. The gels presented a wide range of textural properties as determined by the instrumental and…
Abstract The thickness, length, width, area and perimeter of 575 particles from 16 aqueously dispersed samples of a variety of interstratified clays, smectites and illite have been recorded using TEM techniques. Complete dispersion of the clay material was achieved by saturating the clay with either Na + or Li + , rem…

A metastable phase with the point group symmetry m35 but no ordinary translation symmetry has been found in rapidly quenched (Ti 1−xVx)2Ni alloys with × = 00-0-3 by electron diffraction and high-resolution electron microscopy.
The class of ‘‘facilitated’’ kinetic Ising models introduced in a recent letter is investigated in greater detail. An interpretation of the models in terms of relaxation processes in dense fluids is described. Various types of kinetic behavior are predicted for the different spin models: (A) Arrhenius temperature depe…
Leader peptidase cleaves the amino-terminal leader sequences of many secreted and membrane proteins. We have examined the function of leader peptidase by constructing an Escherichia coli strain where its synthesis is controlled by the arabinose B promoter. This strain requires arabinose for growth. When the synthesis…
A molybdenum containing austenitic steel was exposed in hydrochloric acid at various potentials in the active and passive ranges of the alloys. The surface compositions were analyzed by the ESCA technique. The influence of pretreatment by ion bombardment and mechanical polishing on the passivation behavior was investi…
The equations governing long-wavelength, low-frequency excitations in icosahedral quasicrystals are derived. It is found that while the speeds of the propagating modes are isotropic, the attenuations are not, implying that purely macroscopic experiments can in principle distinguish quasicrystals from crystals, glasses…
This work, a completion of which started in (1), studies the evolution of the mechanical flexural strain of different ranges of mortar samples of 1 X 1 X 6 cm (12 samples/ranges/age/solution) made with sulphoresistant portland cement (P-450-Y, according to RC-75), submerged in filtered drinking water and in the follow…
The study of the suitability of a material for its use as an active addition to the cement and, really, the evaluation of its puzzolanic capacity is a problem which is frecuently present. In this work, a line of behaviour to approach this problem is explained in a practical and definite way, pointing methods of possib…
The petrographical characterization of three spanish sandstones from Villamayor (Salamanca), Somió and Tazones (Asturias) is presented. The significance of the percentage and type of the clay minerals cementing the grains on the pore system geometry, for the rocks studied, is especially emphasized. Besides, correlatio…
