The usual electrical methods of determining thermal conductivities either cannot be used at high temperatures or their use is restricted to substances like carbon or graphite which satisfy certain special requirements. It is shown that the observed temperature distribution along a metal filament electrically heated in…
ABSTRACT Experiments were undertaken to determine the site of water uptake, and the conditions in which it occurs, in Ligia oceanica, Oniscus asellus, Porcellio scaber and Armadillidium vulgare. Besides absorbing water with moist food, all four species were capable of active imbibition of water through both mouth and…
Grain boundary penetrations of radioactive silver into copper bicrystals having a common cubic direction have been measured using an autoradiographic technique. Diffusion occurred along directions forming an angle φ=0°, 45°, and 90° with the common cubic direction. For very low angles of disorientation Θ, no preferent…

Abstract Many supply waters that might be expected to cause pitting corrosion in copper cold‐water pipes containing carbon films do not do so because they contain a natural inhibitor. The inhibitor has not been identified, but it can be shown to be present in these waters and its concentration can be compared roughly…

The sintering and grain growth of alumina as a function of the type of impurity (oxide) added was studied. One weight per cent of the impurity was added to a commercial Be‐grained alumina or was coprecipitated with iilcl 3 to form hydroxides. Fired shrinkage, bulk density, and apparent porosity measurements were used…

In the seventeen years since the publication of F. T. Peirce's "The Geometry of Cloth Structure" [1], many textile engineers have checked the assumptions upon which the geo metric theory is based. Their findings have reflected favorably on Peirce's physical and analytical reasoning. In many cases it was found advisabl…
Following a major shortage of 99Mo in the 2009–2010 period, concern grew that the aging reactor production facilities needed to be replaced. Most producers were using highly enriched 235U (HEU) as the target material. The Organisation for Economic Co-...Read More
slight spread, but there would not be spherical smoothing to the same extent as in the 5 and 10 A reflexions, which are more numerous and at lower angles. The 1.5/t~ reflexion is, therefore, of considerable significance in deciding between a chain structure and a threedimensional net, and it is more profitable to stud…
