Time Of Planting And Rate Of Seeding On Lupin Yield, G Walton Jan 1973

Time Of Planting And Rate Of Seeding On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Of the four time of planting trials twodefinitely showed superiority of earlier seeding (73BA5, 73E6). The two trials in the Southwest (73BR14 and 73MT7) gave highest yields with June sowing compared to May. Three trials (73BR14, 73E6 and 73BA5) appear to have a Variety x Time interaction for plant density, but no definite trend for either Uniharvest or Unicrop although later sowing reduced plant density. Seeding rates in excess of 82 kg/ha gave the highest yields in all trials. The rate of seeding experiments (73BA5 and 73MT7) show that the best crop density for yield (graph) lies between 8 and …

Stratigraphic Comparison Of The Precambrian Wyman And Johnnie Formations In The Western Great Basin, California, Johnnie Nathan Moore Jan 1973

Stratigraphic Comparison Of The Precambrian Wyman And Johnnie Formations In The Western Great Basin, California, Johnnie Nathan Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Precambrian Johnnie Formation in the Death Valley area and to the south is separable into two facies. The southern facies contains six distinct members: the transitional, quartzite, lower carbonate-bearing, siltstone, upper carbonate-bearing, and Rainstorm members. Dolomite, quartzite, and mudstone characterize the southern facies, as does the presence of the Johnnie oolite. To the north the Johnnie oolite pinches out and the amount of mudstone in the formation increases. The dominantly mudstone northern facies contains local gray limestone lenses closely similar to limestone in the Wyman Formation in the White-Inyo Mountains. Generally outcrops of the northern facies of the Johnnie …

Seasonal Movements And Habitat Selection Of Pheasant Cocks In South Dakota, Robert A. Fedeler Jan 1973

Seasonal Movements And Habitat Selection Of Pheasant Cocks In South Dakota, Robert A. Fedeler

Electronic Theses and Dissertations

Data were gathered on seasonal movements and habitat selection of 30 pheasant (Phasianus colchicus) cocks that were radio-equipped in eastern South Dakota from 1970 to 1972. Pheasant cocks stayed in an area of less than 100 acres from spring through hunting season. In winter, cocks used even smaller areas more intensively. Cocks moved about their home range by shifting their activity center rather than by adjustment in range of daily travel. Adult cocks seemed to have strong site attachments on a year-round basis. Immature cocks were more mobile, especially during the fall prior to hunting season. In spring, adult cocks …

The Primary Structure Of Nifungin, Marvin Lee Withrow Jan 1973

The Primary Structure Of Nifungin, Marvin Lee Withrow

Electronic Theses and Dissertations

The primary structure of the antifungal peptide nifungin was studied. Amino acid analysis of nifungin before and after performic acid oxidation revealed 51 amino acids and the presence of an unidentified ninhydrin positive material. The unidentified material constituted approximately ten per cent of nifungin by weight. It contains nitrogen but, as reported by others (2), did not contain phosphate or reducing sugars. It was not hydrolyzed into smaller compounds by strong mineral acids. Carboxyl terminal analysis was conducted utilizing carboxy-peptidase A and B on both the oxidized and unoxidized nifungin. Tyrosine appeared to be released most rapidly followed by lysine, …

Carbon Interstitial In The Diamond Lattice, C Weigel, David Peak, J W. Corbett, R P. Messmer, G D. Watkins Jan 1973

Carbon Interstitial In The Diamond Lattice, C Weigel, David Peak, J W. Corbett, R P. Messmer, G D. Watkins

All Physics Faculty Publications

Linear-combination-of-atomic-orbitals-molecular-orbitals cluster calculations using the extended Hückel theory are carried out for the interstitial carbon in the diamond lattice. The results suggest that the interstitial configuration is not the tetrahedral or hexagonal site, as has been previously assumed, but is instead an "interstitialcy" configuration, i.e., either a split- 〈100〉 interstitial (which our results favor) or a bond-centered interstitial. The predicted minimum-energy configuration changes with charge state, suggesting that the interstitial in the diamond lattice is a possible example of the Bourgoin mechanism of athermal migration of a defect in the presence of ionizing radiation.

Ionization‐Enhanced Diffusion: Ion Implantation In Semiconductors, J Bourgoin, David Peak, J W. Corbett Jan 1973

Ionization‐Enhanced Diffusion: Ion Implantation In Semiconductors, J Bourgoin, David Peak, J W. Corbett

All Physics Faculty Publications

A model for the diffusion of implanted interstitials during implantation is introduced and shown to be able to account for the tails observed in ion profiles. It is argued that mechanisms of ionization‐enhanced diffusion can explain some of the anomalous diffusion mechanisms observed in semiconductors. Indications for the existence of such mechanisms in the field of ion implantation in semiconductors are discussed.
