The Effect Of Ferrous And Ferric Ions On The Conversion Of Malate To Pyruvate By A Cell Free Extract Of Pigeon Liver, Keith Erwin Richardson
The Effect Of Ferrous And Ferric Ions On The Conversion Of Malate To Pyruvate By A Cell Free Extract Of Pigeon Liver, Keith Erwin Richardson
Theses and Dissertations
Recent investigations on the crude pigeon liver extracts have shown the presence of an enzyme which catalyzes the oxidative decarboxylation of malate to pyruvate and carbon dioxide. The name malic enzyme has been given to this enzyme to distinguish it from malic dehydrogenase. Under aerobic conditions the addition of ferrous sulfate resulted in inhibition of the action of malic enzyme. Subsequent investigation showed that the inhibition obaerved was not due to ferrous ions, but due to ferric ions which were contaminating the ferrous sulfate. It was also shown that under aerobic conditions ferrous ions were rapidly oxidized to ferric ions. …
A Study Of The Families Of Utah Hemiptera, Gerald L. Nielsen
A Study Of The Families Of Utah Hemiptera, Gerald L. Nielsen
Theses and Dissertations
This study determines the number of families of Hemiptera found in the state and has a key for their classification. The characteristics and general distributions of each family are given, along with specific examples of the most common and economically important bugs. Important references are given for each family of work done to date. It was found that there have been twenty-eight families of Hemiptera collected in Utah, some of which are well represented in numbers of genera, species, and individuals, while others are represented by a single species and collected in only one or two places in the state.
An Ecological And Distributional Study Of Small Mammals Of Cedar Valley, Utah County, Utah, Loraine Woodbury
An Ecological And Distributional Study Of Small Mammals Of Cedar Valley, Utah County, Utah, Loraine Woodbury
Theses and Dissertations
This paper deals with the ecology and distribution of small mammals in the following plant communities of Cedar Valley, Utah: juniper, greasewood, grass-rabbitbrush, and shadscale. Study periods were in August 1950 and 1951, October 1951, and April 1952 with each community studied 1,440 trap-nights. A combination of the Calhoun ''B" and transect method was employed; plant species and densities were taken and soil samples were checked for moisture content, total soluble salts and mechanical analysis. In the communities studied Dipodomys ordii utahensis (Merriam) is found in greatest abundance on sandy soil and Perognathus parvus olivaceus (Merriam) is found in greater …

The Succession Of Vegetation On A Southern Utah Sand Dune, Elias S. Castle
The Succession Of Vegetation On A Southern Utah Sand Dune, Elias S. Castle
Theses and Dissertations
The sand dunes lying ten miles northwest of Kanab in Kane County, Utah, support a sparse plant cover with four species dominating the vegetation: Psoralea stenostachys, Sophora stenophylla, Oryzopsis hymenoides, and Wyethia scabra var. attenuata. Of these Psoralea and Wyethia are endemic to the dunes or to a limited area which includes the dunes. The pineer species gain a start in the valleys between dunes and occupy the area only until sand covers them or until sand is blown away from their roots. Stabilization of the soils is not permanently in the interdune valleys and the dunes continue to wander. …

The Chromatographic Purification Of Human Red Blood Cell Acetylcholinesterase, Richard P. Dunkley
The Chromatographic Purification Of Human Red Blood Cell Acetylcholinesterase, Richard P. Dunkley
Theses and Dissertations
A process of column chromatography of human erythrocyte acetylcholinesterase, using a cationic exchange resin, was investigated as a possible method for the primary partial purification of the enzyme on a large scale. The investigation was based, first; on a detailed study of the enzymatic stability to variation in hydrogen-ion and salt concentrations for periods of time extending to forty eight hours and, second; on an investigation of the degree of adsorption by the resin of the enzyme at various pH values within the pH range of enzyme stability. A method for the analysis of the enzyme activity of large numbers …

Biological Oxidation Of Copper Sulfide Minerals, Delmar Boyd Davis
Biological Oxidation Of Copper Sulfide Minerals, Delmar Boyd Davis
Theses and Dissertations
This work represents a study of the biological oxidation of copper sulfide minerals. The principal objective of the study was to determine the extent of bacterial oxidation on copper containing sulfide minerals. It was also desired to determine if the bacteria could oxidize copper sulfides in the absence of iron. A better understanding of the nitrogen requirements of the organisms was desired. Minerals used in this study were Bingham Canyon Float Concentrate, chalcopyrite, covellite, calcocite, bornite, tetrahedrite, and reagent grade copper sulfide. The bacteria used were obtained from the mine waters of Bingham Canyon, Utah. To study the problem the …

This paper deals with the complete skeletal anatomy ot Bolitoglossa rufescena (Cope). All parts are figured and described. In addition to this many of the main skeletal parts of Bolitoglossa platydactyla (Cuvier) Bolitoglossa occidentalis Taylor, and Bolitoglossa flaviventris (Schmidt) are described and figured. A comparison of the following parts of the above mentioned salamanders is presented: skull, atlas, ninth trunk vertebra, sixth caudal vertebra, carpals, tarsals and digits. The similarities and differences are pointed out as they appeared to the author. The relationship and specialization ot these species is discussed rather briefly.
