Recycling Surplus Oil Funds And The Economies Of Some Non-Oil Producing Developing Countries, Patrick E. Archibong

Economic and Financial Review

The main objective of the paper is to examine, in general, the phenomenon of recycling against the background of enduring and fundamental disequilibria in the payments balances of the economies of non-oil producing developing countries. The technique used is, essentially, casual empiricism. In part I of the paper a brief attempt is made, using elementary micro-economic analysis, to illustrate conditions for the emergence of the surplus oil funds. Part 1 examines the mechanics and_ channels of recycling while Part 111 reflects on the attendant external debt burden of some non-oil producing developing countries. Part IV dwells on the limited effectiveness …

The Future Of Coastal Zone Management: The 1980 Amendments, Kenneth J. Buckland

Marine Affairs Theses and Major Papers

The Federal Coastal Zone Management Act of 1972 (P.L.98-583) is currently being questioned on its validity, purpose, funding, wording, and accomplishments in carrying out national policies for the benefit of the U.S. coastal zones. All the legislation promulgated for management of coastal resources, the agencies involved in coastal zone management, and the groups participating in these actions have been challenged in recent months and have subsequently been evolving in their functions. What remedies are available and how they could be realized through the present federal laws and organizational structure are areas which must be discussed now if we are to …

Relationship Between Rainfall And Storm Runoff For Selected Arizona Watersheds, Robert James Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship between rainfall and runoff was examined for twelve selected Arizona watersheds. Expedient runoff volume model coefficients and runoff curve number model parameters were examined using standardized structure, with modifications to adjust the model for small initial abstractions and large watershed storage capacity.

Forest-land management practices were examined for their effects on curve number coefficients. The effects of rainfall characteristics were also evaluated with respect to changes they induce in curve number populations.

Evaluations included a runoff fraction, a simple multiplier of storm volume to produce runoff volume. The accuracy of this model is promising for more permeable watersheds.

Allocation Of Reproductive Effort To The Male And Female Strategies In Wind-Pollinated Plants, Cliff A. Lemen

School of Natural Resources: Faculty Publications

Amaranthus and several other wind-pollinated species of plants are used to test some of the theoretical models of relative reproductive effort towards the male and female sexes. Consistent with these models, in self-compatible, monoecious Amaranthus, Chenopodium, Digitaria, Setaria, and Lepidium, female effort represented over 90% of the total reproductive effort. Also consistent with predictions, Lolium, a self-incompatible wind-pollinated species, was found to have about equal male and female effort. A method is described here that should prove useful in quantifying male and female effort in both wind and insect-pollinated species of plants.

Relationship Between Relative Brain Size And Climbing Ability In Peromyscus, Cliff A. Lemen

School of Natural Resources: Faculty Publications

Eisenberg and Wilson (Evolution, 32:740-751, 1978) have documented an interesting relationship between the relative brain size of bats and the complexity of the habitat in which they forage. They found that bats that fly and forage through foliage have larger brains relative to their body size than those that forage in open air. Their explanation was that bats in the complex habitat must process more complex sonic information to navigate through the foliage. In order to do this a larger brain is required.

The Peromyscus of North America may offer a similar paradigm as far as habitat complexity …

Armadillos: Problems And Control, Patricia A. Chamberlain

Vertebrate Pest Conference Proceedings: 9th (1980)

The nine-banded armadillo (Dasypus novemcinctus) has been successful in extending its range throughout the southeastern states. It occupies such a diverse range of habitats that its effects on its surroundings depend largely on where it is located. It offers benefits from its burrowing and eating patterns by creating dens for furbearers and destroying large quantities of injurious insects and their larva. Those same activities in urban and suburban areas are now being recognized as a source of considerable nuisance and moderate damage. Damage is most severe from July through early November. They have been recognized in connection with several diseases …

Avitrol-Treated Bait For Protection Of Grapes From House Finch Damage, Lee R. Martin, William T. Jarvis

Vertebrate Pest Conference Proceedings: 9th (1980)

Damage to grapes by house finches (Carpodacus mexicanus) is widespread and well documented in California. DeHaven (1974) estimated that damage in nine counties exceeded 0.75 million dollars while Clark (1976) indicates a probable loss of 3.7 million dollars throughout the entire state. Crase et al. (1976) indicated that house finches undoubtedly are the principal depredating species. Various protection measures are described by Piper & Neff (1937), Boudreau (1972), and Clark (1975, 1976). Current protection programs are explained by Crabb and Martin (1977).

Taste-Aversion Learning And Its Implications For Rodent Control, Robert J. Robbins

Vertebrate Pest Conference Proceedings: 9th (1980)

Although bait shyness has long been recognized as a problem to be overcome in the control of vertebrate pests, it has recently been suggested that the phenomenon might be turned to an advantage and used as an alternative, non-lethal form of control. Unfortunately, this technique has not proven to be as useful as hoped, as the work which has been done on coyotes is inconclusive at best and some recent work on rodents has cast serious doubts upon the method's potential. However, an extensive literature dealing with the formation of poison-based food aversions now exists, and insights gained from these …

Efficacy Tests Of Different Rodenticides On Some Species Of Rats In Thailand, Kasem Tongtavee

Vertebrate Pest Conference Proceedings: 9th (1980)

Two acute rodenticides, zinc phosphide and Vacor, at different concentrations were tested on the rice field rats (Rattus argentiventer) and the bandicoot rats (Bandicota indica) with a choice-feeding procedure. It was found that zinc phosphide at 0.5%, 0.8%, 1.6% caused 30%, 30%, and 60% mortality, respectively, to R. argentiventer, and at 1.6% caused death only 30% to B. indica, whereas Vacor at 0.5%, 0.8%, 1.6% caused 70%, 60% and 80% mortality, respectively to R. argentiventer and this compound at 1.6% killed 60% of B. indica. Five anticoagulants Actosin-P, warfarin, Racumin, brodifacoum, and chlorophacinone also were tested on R. argentiventer and …

Rat Control In Coconut Palms In Colombia, Danilo Valencia

Vertebrate Pest Conference Proceedings: 9th (1980)

The black rat (Rattus rattus) causes severe damage to coconut (Cocos nucifera) crops in Colombia. These rodents climb to the crown of producing palms and often nest there. Damage results from the rats gnawing the shells of the coconuts until they penetrate to the endosperm; the perforated nuts will fall within a period of 15 days and are unsuitable for harvest.
Since 1972, the Colombian Agricultural Research Institute (Instituto Colombiano Agropecuario or ICA), through its Vertebrate Control Program, has been conducting a series of investigations to obtain information about the characteristics of this damage and the best means of reducing …

Mammals And Birds Affecting Food Production And Storage In Nigeria, Oluwadare Funmilayo

Vertebrate Pest Conference Proceedings: 9th (1980)

The systematic study of the roles of vertebrate pests in agriculture in Nigeria is relatively very young, having spanned only two decades. During this period the species composition of vertebrate pests has been determined in some important crop plants like cocoa (Taylor 1961, Everard 1968), oil palm (Greaves 1964), maize (Everard 1966; Funmilayo 1976) and rice (Funmilayo and Akande 1977). The ecology of a few important pest species has been studied. Because of its devastating destruction of many graminaceous crops in Nigeria and over most parts of Africa, the red-billed quelea (Quelea quelea) has been studied more intensively than other …

Compensatory Response Of Maturing Corn Kernels Following Simulated Damage By Birds, Paul P. Woronecki, Robert A. Stehn, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

(1) A study was made to measure compensatory growth responses and to estimate losses associated with bird damage to maturing corn.
(2) Corn kernels contain 20-40% of their final biomass at the time they are usually consumed by blackbirds.
(3) Very slight compensation of kernel weight occurred following simulated bird damage to tip kernels.
(4) Heavy bird damage, early in kernel development, increased fungal, sprouting, and insect damage before harvest.
(5) Estimates of bird damage, subsequent secondary damage, and compensation were affected by the amount of damage, maturity of the kernels at the time of damage, and environmental factors before, …

A Comparative Water Quality Study Of Man-Made Drainage And Natural Streams, Kent W. Boyum

Journal of the Minnesota Academy of Science

The effects of man-made drainage systems on the water quality of receiving bodies Is relatively unknown. During the ice-free season of 1979, thirteen drainage ditches and f our rivers were sampled at intervals of three to eight days. With increasing flow, total orthophosphatephosphorous, total Kjeldahl-nitrogen, nitrate-nitrogen and total dissolved solids increased, but not proportionately to f low, with total orthophosphate-phosphorous showing the least proportionality. Variation was observed in each ditch and river when broken down seasonally for each parameter. Generally, when the percentage of flow was greater in one of the three seasons, the percentage of each of the other …

Land-Cover Changes In A River Valley In Blue Earth County, Minnesota, 1938-1974, Corrie Schaffer Cowley

Journal of the Minnesota Academy of Science

The boundary of the Blue Earth River Valley was determined by stereoscopic viewing of 1938-39 aerial photographs. The same boundary was then drawn on corresponding 1974 photographs. All area within the river valley was assigned to one of four land-cover. Comparison of 1938-39 to 1974 shows a decrease of 19 percent in river area, an increase of one percent in row crop area, an increase of 52 percent in tree area, and a decrease of 45 percent in scrub area.

A Survey Of Water Flow In Drainage Ditches And Streams In South Central Minnesota, Clay Pierce, Bill Thompson

Journal of the Minnesota Academy of Science

Discharge was monitored on 13 agricultural drainage ditches and 4 small rivers in south central Minnesota. Derived data were categorized by response to hydrologic events and stream order. Stream order was found to be the most reliable predictor of hydrologic event response. Peak flows in drainage ditches were found to correspond to peak flows in rivers.

The Rush Creek – Lisco Structural Basin, Garden And Morrill Counties, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Detailed field mapping of outcrops in southern Garden and Morrill counties, Nebraska, has revealed a drop of more than 60 m (200 ft) in 4.8 km (3 mi) in the elevation of the contact between the Brule Formation and the Ogallala Group as exposed on the east side of Rush Creek. Beds of silt, sand, siltstone, and volcanic ash locally dip to the northwest at angles up to 8.5'. The contact between the two formations cannot be seen on the west side of Rush Creek but beds in the Ogallala Group there dip to the north and northeast. Rocks north …

A Preliminary Study On Expanding And Financing State Water Development, Daniel H. Hoggan, Kirk R. Kimball, Jay M. Bagley

Reports

The effects of recent energy price increases, domestic inflation rates, financial market fluctuations, and changing public attitudes toward federally sponsored water resource development and management have brought economic and financial consideratiosn to the forefront of Western water management issues. Recently enacted federal policies place increased responsibility on the states and localities for the development and management of their water resources. A response common to many of the western states has been to stengthen traditional, and often small, water financing and development programs. In creating and sustaining such a posture, however, state governments must address the important questions pertaining to the …

Management Of Rural Domestic Water Systems In Utah, Trevor C. Hughes

Reports

Introduction: There are now more than 400 community type public drinking water systems in Utah. Considerable state and federal assistance is available for construction or renovation of such systems, but once the system is constructed and the consulting engineer leaves, the managers of the smaller systems find themselves quite isolated from sources of professional assistance. The larger systems have a revenue base which can provide ongoing services of a consultant or salaried engineer and well trained operators. The smaller systems, particularly low density rural systems where the length of pipeline per user is very high, usually find themselves barely able …

Groundwater Heat Pump Equipment Selection Procedures For Architects, Designers, And Contractors, Calvin G. Clyde, Edward W. Vendell, Kirk D. Hagen

Reports

Engineers at the Utah Water Research Laboratory and the Mechanical Engineering Department at Utah State University have investigated the use of groundwater heat pumps for residential space heating and cooling in the Utah climate. They have found that this type of system conserves energy and may cost less for Utah home owners to operate than many conventional heating and cooling systems. Since the use of groundwater heat pumps will probably become more widespread in the near future, building and heating contractors should become more informed about what a groundwater heat pump is and how it works. The purpse of this …

Some Historical Accounts Of The Natural Conditions In Tampa Bay And Hillsborough County, Michael Heerschap

Reports

As we might expect as we read on in the literature we find that as Tampa grows, then the animals and fish which were so abundant slowly disappear. An interesting feature of these accounts are the stores told of mass killings of animals and birds for no reason except for fun. Also included are some tales of our notorious insect life and thundershowers. This report is a collection of some of the more interesting quotes from various sources.
