Granular Fertiliser, C R. Hale Aug 1956

Granular Fertiliser, C R. Hale

Experimental Summaries - Plant Research

There is general agreement that granulation of fertilisers improves their physical characteristics with respect to handling, storage and distribution in the field. These physical advantages rather tan any established agronomic reason appear to be responsible for the increasing use of granular fertiliser.

The Lateral Vibrations Of An Axially Rotating Bar, William C. Mccorkle Jr Aug 1956

The Lateral Vibrations Of An Axially Rotating Bar, William C. Mccorkle Jr

Doctoral Dissertations

Introduction: It has long been known that the rotational motion of a bar or shaft at certain speeds is capbable of exciting lateral vibrations of the shaft. Almost invariably these vibrations are undesirable or even destructive, and for this reason considerable attention has been given to their study. The subject has a fairly extensive literature dating back to 1869 when Rankine1,2 first treated the stability of a shaft, running true and in perfect balance, against small disturbances. His results were erroneous because he assumed that the plane of vibration always rotated with the shaft, which is equivalent to neglecting …

A Study Of The Catalytic Hydrogenation Of Methoxybenzenes Over Platinum And Rhodium Catalysts, Robert Gene Thompson Aug 1956

A Study Of The Catalytic Hydrogenation Of Methoxybenzenes Over Platinum And Rhodium Catalysts, Robert Gene Thompson

Doctoral Dissertations

[From the Summary]

The catalytic hydrogenation of methoxybenzenes and other aromatic methoxyl compounds has been studied. Hydrogenation of the aromatic ring was usually accompanied by some cleavage of the methoxyl groups. This cleavage occurred predominately upon the carbon-oxygen bond adjacent to the aromatic ring. The cleavage reaction was found to occur only as a part of the aromatic hydrogenation process. The amount of cleavage was found to be dependent upon the catalyst used. Platinum led to extensive methoxyl cleavage while rhodium catalyzed ring saturation with little cleavage. Also found to influence the extent of cleavage were reaction temperature …

Oxidation Of Molybdenite With The Aid Of Microorganisms, Ralph Anderson Aug 1956

Oxidation Of Molybdenite With The Aid Of Microorganisms, Ralph Anderson

Theses and Dissertations

This work represents a study on the biological oxidation of molybdenite, MoS2. The principal objective of this study was to investigate the possibility of the biological oxidation of molybdenite, to determine the physical and chemical conditions under which the oxidative process occurs, and to develop a strain of bacteria or alter the activity of the microorganisms by acclimatization to increase their activity on sulfide minerals, in particular molybdenite. Minerals used in this study were pyrite (FeS2), chalcopyrite (CuFeS2), molybdenite concentrate, and molybdenite ore. The microorganisms used in this investigation were autotrophic bacteria obtained from the leaching streams of Bingham Canyon, …
