Soil pH and Base Status as Factors in the Distribution of Calcicoles
It is a well-known fact that many species of wild plants are characteristic of limestone and other base-rich neutral soils and are loosely termed calcicoles, and there is a corresponding group characteristic of acid soils poor in bases termed calcifuges. In this paper is reported an attempt to discriminate between som…
Electrostriction
The term ferroelectricity is briefly introduced and the properties of the perovskite-structure mixed-oxide group are reviewed with special reference to BaTiO 3 . The distinction between piezoelectricity and electrostriction is explained in some detail, and the relevant expressions relating the electrical and mechanica…
Viskosimetrische molekulargewichtsbestimmung von cellulose in kupfer‐äethylendiamin
Abstract Cellulose löst sich in Kupferäthylendiamin („Cuën”︁) schneller und ist gegen Luftsauerstoff beträchtlich unempfindlicher als in Cuoxam. Im Gegensatz zu amerikanischen und französischen Arbeiten wurde festgestellt, daß Lösefähigkeit und Viskositätszahl weitgehend unabhängig von der Zusammensetzung des Komplexe…
Die reaktion des α, α‐diphenyl‐β‐pikryl‐hydrazyls mit langkettigen freien radikalen, die beim ultraschallabbau von polymethacrylsäuremethylester gebildet werden
Abstract Beim Abbau des Polymethacrylsäuremethylesters durch Ultraschallwellen entstehen langkettige freie Radikale, die mit gleichzeitig vorhandenem α,α‐Diphenyl‐β‐pikryl‐hydrazyl (DPPH) reagieren. Erfolgt der Abbau unter Ausschluß von Sauerstoff, werden pro gespaltene Bindung zwei Moleküle DPPH verbraucht. Spektrosk…
The Effect of Alloying Elements in Iron on Hydrogen Over-voltage and Corrosion Rate in Acid Environments
Alloying elements commonly found in steel were added to pure iron to establish their effect on hydrogen overvoltage and corrosion rate in 0.1 M citric acid ( p H 2.06), 0.1 M malic acid ( p H 2.24), and 4% sodium chloride at p H 1 and 2. Sulfur, phosphorus, and carbon proved detrimental to corrosion resistance. Copper…

MINERALS OF BISMUTHINITE-STIBNITE SERIES WITH SPECIAL REFERENCE TO HOROBETSUITE FROM THE HOROBETSU MINE, HOKKAIDO, JAPAN
Horobetsuite occurs associated with free sulphur and iron sulphide minerals, in the sulphur deposit of Horobetsu Mine. The chemical formula of horobetsuite has been determined as (Bi, Sb)2S3. The molecular ratio of Bi2S3 to Sb2S3 varies between 9:11 and 13:7. The mineral is intermediate between bismuthinite and stibni…

Magnetic Fields in Small Ferrite Bodies with Applications to Microwave Cavities Containing Such Bodies
The microwave magnetic field in a small ferrite sphere and thin circular cylinder is found in first approximation. In a circularly polarized exciting field the internal field is again circularly polarized. The ratio of the internal field to the exciting field is 3(µ±α+2)-1 for the sphere and 2(µ±α+1)-1 for the cylinde…

The Anodic Treatment of Aluminum in Sulfuric Acid Solutions
High purity aluminum was anodized in sulfuric acid solutions at various concentrations (5– 50%), temperatures (10°– 50°C), time periods (2 – 60 min), and current densities (1.7 – 6.2 amp/dm 2 ). The coating weight, metal loss, coating ratio, sealing weight gain, dyed color, density, and coating chemical dissolution ra…
Thermoelectric Behavior of Nickel Oxide
Measurements have been made on the thermoelectric power of several nickel oxide samples containing foreign ions. Using an energy model recently proposed for nickel oxide, the effect of the nature and concentration of additions on the Fermi level, hole concentration, and mobility is derived and discussed. For most of t…
