The Addition Of Sf5br To Unsaturated Systems, Qui-Chee Wendy Wang

Dissertations and Theses

Addition reactions of pentafluorosulfur bromide with unsaturated substrates were studied and four new compounds containing the pentafluorosulfur group have been prepared.

The mechanism for these reactions seems to involve a radical addition pathway. In reaction with CH₂=CFC1, CF₃C≡CH and CH₃C≡CH the SF₅ radical attacks the carbon atoms carrying the most hydrogens. The reaction with CF₂=CHCl is interesting, as by analogy with other fluoroolefins, the SF₅ primary attack should occur.at the CHCl group, however, SF₅CF₂CHC1Br was found as the only product for this reaction. The reaction of …

Bulletin No 3993 - The Control Of Saffron Thistle, G. A. Pearce

Bulletins - 3000 - 3999

Saffron thistle is a primary noxious weed and is widespread throughout the drier parts of Western Australia. When growing in pasture its prickly growth habit discourages animals from grazing amongst it so that its presence results in the loss of feed. In crops it reduces yield and results in dockage when seed is found in harvested grain.

The Effect Of Pre-Admission Crisis Nursing Intervention On The Anxiety Level Of Elderly Persons On Admission To A Nursing Home, Doreen C. K. Lee

Loma Linda University Electronic Theses, Dissertations & Projects

The experimental study attempted to determine whether pre-admission crisis nursing intervention had any effect on the level of anxiety of elderly people when they were transferred from an acute hospital to a nursing home.

The literature review related to trends in numbers of nursing homes and in the increase in longevity. Several articles indicated that the aged, as a group, lacked power to alter their situations. The need for patients to express their feelings and participate in their own decisions was stressed in various studies. Other theories discussed theoretical aspects and goals of crisis intervention. Several articles suggested that crisis …

Distribution Of Carbonate In Surface Sediments Of The Pacific Ocean, W. H. Berger, Charles Adelseck, Larry A. Mayer

Affiliate Scholarship

The distribution of carbonate on the floor of the Pacific has been remapped on the basis of 1313 points from 80 references stored in the World Ocean Sediment Data Bank of Scripps Institution of Oceanography. Percent distribution maps and carbonate versus depth diagrams generally agree with previously published information and reflect the major controlling factors of carbonate sedimentation (depth, hydrography, fertility, and sedimentary processes). While carbonate distributions are of limited use in attempting to construct dissolution profiles, major trends are identifiable. In particular, the degree of lowering of the equatorial calcite compensation depth (CCD) together with an estimate of the …

Distribution Of Stream Pollution In Lake Water, Richard W. Tew, Samuel S. Egdorf, James E. Deacon

Publications (WR)

Wastewater effluent-laden waters from Las Vegas Wash (LVW) form a density current that may be detected in Boulder Basin of Lake Mead at considerable distances from the wash estuary. This led to the suspicion that water from the inflowing stream [40 mgd (1.5 X 10⁵ cu m/day)] might not be rapidly diluted in the enormous volume of the lake [19 mil acre-ft (2.3 X 10¹⁰ cu m)], but might persist as a recognizable entity to the vicinity of the intake of a major water source for populous Clark County, Nev.

Because of the detection sensitivity implicit in the …

Analysis Of The Presettlement Forests Of The Unglaciated Portions Of Southern Illinois, Lawrence A. Leitner

All-Inclusive List of Electronic Theses and Dissertations

This research used the data on witness trees found in the surveyors' records of the General Land Office surveys of 1805-1815 as the basis for studying the primeval forests of unglaciated southern Illinois. Via computer, the random pairs and closest individual methods of plotless sampling were used to develop stand attributes tables, with soil association boundaries defining the limits of forest stands. A vegetation map was developed from these stands. Four major forest types were delineated: Upland Oak, nixed Hardwoods, Swamp Forest, and Floodplain Forest. The Upland Oak Forest, with lowest density (175.9/ha or 71.2/acre) and basal area (21.3 rn …

Nitrogen Fertilization Studies In Dryland Winter Wheat And Potential Nitrogen Losses From The Soil At The Blue Creek Experimental Station In Northern Utah, Subhawat Intalap

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study compared the effects of nitrogen sources on the available inorganic soil nitrogen, nitrogen movement, nitrogen losses, and wheat yields when nitrogen fertilizers were applied to soil planted to dryland winter wheat at the Blue Creek Experimental Station in northern Utah.

In the fall 1973 soil samplings, the fertilizers producing the largest mineral nitrogen contents in the 0-30 cm soil depths were ammonium nitrate >ammonium sulfate > S-coated urea, when they were broadcast at the practical rate of 56 kg N/ha. There was no increase in the mineral nitrogen at the dee per depths in the fall or at any …

Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nomadic pastoralism has been the traditional method of utilizing grazing resources in arid and semi-arid regions of Africa. However, increased sedentarization accompanied by growing human and animal populations during the past two decades is thought to be accelerating the desertification process, or desert expansion. The specific interactions of the grazing animal with this process has been speculated upon but not studied in detail. A comparative study was initiated during the spring grazing season of 1974 to determine sheep and goat nutritional and production responses, as well as patterns of vegetative selection and utilization under the pastoral system currently employed in …

Irrigation Scheduling Program For Sugarcane, Terence L. Pearse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An estimate of potential evapotranspiration is acquired to implement an irrigation scheduling program. Four equations, which estimate potential evapotranspiration (evaporation) were evaluated for prediction of Class "A" Pan evaporation. The equations used were Penman's combination equation, the Jensen-Haise temperature and radiation equation, and two of the Christiansen-Hargreaves polynomial regression type equations. Measured and calculated radiation was used together with two values of albedo. Four years of daily climate data from Rhodesia was evaluated by general linear regression methods.

Despite the significant variations between the four annual regression lines of each equation, the use of confidence intervals indicate that the Penman …

The Nature And Distribution Of Enteric Bacteria In Las Vegas Bay, Samuel S. Egdorf

Publications (WR)

The distribution of water and of enteric bacteria of possible fecal origin into Las Vegas Bay from Las Vegas Wash was determined. Determination of distribution patterns was attained by applying the concept of the population component ratio of enteric bacteria. The development and application of new techniques and methods implicit in the application of the "component ratio" concept are discussed. The unreliability of thoroughly referenced techniques and methods generally accepted as standard are treated in detail. Physical factors affecting the distribution and deposition of enteric bacteria (including those of special public health importance) in Las Vegas Bay are also discussed.

Reactions Of N-Ethoxycarbonylthioamides With Dinucleophilic Reagents, Babu George

Chemistry and Chemical Biology ETDs

When an N-ethoxycarbonylthioamide is treated with dinucleophilic reagents containing a primary or secondary amino group and another nucleophilic group, reaction occurs initially between the amino group of the reagent and the thiocarbonyl of the substrate with elimination of hydrogen sulfide and formation of a carbon, nitrogen double bond. The intermediate thus formed may subsequently cyclize in either of two different manners depending upon the relative positions of the two nucleophilic groups in the reagent. A. If the second nucleophilic group is adjacent to the amino group, or separated from it by one carbon atom, cyclization involves nucleophilic attack at the …
