Algae of selected continental and maritime bogs in North America
Algal taxa (281) were identified from 31 ombrotrophic bogs and 3 weakly minerotrophic fens from Manitoba to Newfoundland. Species richness increases from continental to maritime and coastal bogs, mainly as a result of an increase in Chlorophyta, especially Desmidiaceae. Species richness is related to (i) availability…

Polarization effects in elastic photon-atom scattering
We have calculated two linear polarization effects in the elastic scattering of x rays and \ensuremath{\gamma} rays (in the energy range a few keV to little above 1 MeV) from targets with Z ranging from 13 to 92, using Rayleigh scattering amplitudes obtained numerically with the procedures of Kissel et al. We consider…

Review of high temperature corrosion of metals and alloys in sulphidizing/oxidizing environments II. Corrosion of alloys
A review ofthe corrosion ofalloys in oxidizing/sulphidizing environments is presented,with specialemphasis on high temperature alloys. As in part I* of this work which dealt with corrosion in pure metals, the simultaneous formation ofoxide and sulphide is considered in detail by describing possible reaction paths and…
Reflective multicolor liquid-crystal display
A reflective multicolor matrix LCD with micro color filters is investigated. In order to improve the brightness of the LCD, contrast and brightness of various liquid-crystal display modes are analyzed. This analysis suggests the choice of the phase-change-type guest-host mode. The optimal parameters for this mode are…

Techniques for determining thermal conductivity and heat capacity under hydrostatic pressure
The paper describes a method for measuring the pressure dependence of the thermal conductivity and the heat capacity of hard materials and single crystals. Two parallel metal strips are evaporated onto a flat surface of the specimen, one being used as a heater, the other as a resistance thermometer. The appropriate th…

Effect of cryo‐ground rubber on melt flow and mechanical properties of polypropylene
Abstract The influence of cryo‐ground rubber (CGR) on melt flow and mechanical properties of polypropylene has been investigated. Cryo‐ground rubber was incorporated in the polypropylene matrix (a) in powder form and (b) as masterbatch with natural rubber. Natural rubber was found essential as a dispersing agent. The…
Compositionally Graded Semiconductors and Their Device Applications
This paper reviews the electronic transport properties of compositionally graded materials. Band gap grading is a powerful tool for engineering the energy band diagram of a device and thus modifying its electrical transport properties (band gap engineering) (1). The most interesting property, which has far reaching co…
Relationship Between Illite/Smectite Diagenesis and Hydrocarbon Generation in Lower Cretaceous Mowry and Skull Creek Shales of The Northern Rocky Mountain Area
Abstract The percentage of expandable layers in illite/smectite (I/S) mixed-layer clay decreases with increasing temperature and depth in a section through marine Cretaceous shales in the Champlin 1 Hartley Federal well in the Powder River basin, Wyoming. This systematic change in I/S expandability is evidence that lo…
Clock-model description of incommensurate ferroelectric films and of nematic-liquid-crystal films
The transmission electron micrographs of submicrometer-thick specimens of incommensurate barium sodium niobate obtained by Xiao-qing et al. exhibit textures with lines of disclinations ending in vertices of Friedel index m=+1. These are similar to those observed in nematic-liquid-crystal films with continuously degene…
Mo-MoO2(MOM) oxygen buffer and the free energy of formation of MoO2
The chemical potential of oxygen defined by the Mo-Mo02 equilibrium has been measured between 1000 and 1400 K using an electrochemical method. The results are /J-~rMo02 = -603268 + 337.460T - 20.6892T In T in joules per mole (:t 140 J .mol-I). These results show that the small increment to the calorimetrically measure…

Location and analysis of byssal structural proteins of Mytilus edulis
The acellular attachment organ (byssus) of the marine mussel Mytilus edulis L. is composed of threads that emanate from the body of the mussel to adhesive discs that anchor the threads to rocks, sand and other mussels. Three proteins have been purified by immunohistological methods and located to specific regions of t…
