Fapri Trade Model For Feed Grains: Specification, Estimation, And Validation, Aniss Bahrenian, S. Devadoss, William H. Meyers Dec 1986

Fapri Trade Model For Feed Grains: Specification, Estimation, And Validation, Aniss Bahrenian, S. Devadoss, William H. Meyers

CARD Staff Reports

This model was developed to quantify the trade and policy linkages for feed grains among the major importing and exporting regions. It is intended primarily for use in making intermediate-term projections and conducting policy impact analysis. Thus it is a relatively small partial equilibrium model but incorporates the most basic supply, demand, price, and policy variables in the feed grains sector.

Late Pleistocene Sciurids From Kokoweef Cave, H. Thomas Goodwin Dec 1986

Late Pleistocene Sciurids From Kokoweef Cave, H. Thomas Goodwin

Loma Linda University Electronic Theses, Dissertations & Projects

Three local (Tamias panamintinus, Ammospermophilus leucurus and Spermophilus variegatus) and five extralocal (Tamias minimus, Tamias palmeri, Marmota flaviventris, Spermophilus townsendii, and Spermophilus lateralis) sciurid species (Sciuridae) were identified from the late Pleistocene-early Holocene Kokoweef Cave paleofauna. This fauna was the first documentation of T. minimus, T. palmeri and S. townsendii from the Pleistocene of the Mohave Desert. The 30-ft sedimentary sequence apparently recorded the mid-to late-Wisconsian introduction of S. lateralis into the Kokweef fauna but otherwise documented general taxonomic stability. The ecological diversity of the fauna was consistent with--but did not require--the hypothesis of more equable late Pleistocene climates, and ...


The Homeo Domain Of A Murine Protein Binds 5' To Its Own Homeo Box., Abraham Fainsod, Leonard D. Bogarad, Tarmo Ruusala, Martin Lubin Dec 1986

The Homeo Domain Of A Murine Protein Binds 5' To Its Own Homeo Box., Abraham Fainsod, Leonard D. Bogarad, Tarmo Ruusala, Martin Lubin

Dartmouth Scholarship

Nuclear protein extracts from day 12.5 mouse embryos were used to study protein binding to DNA sequences 5' of the Hox 1.5 homeo box. Embryos of this developmental stage are known to express this gene. DNA binding protein blotting and retardation gel techniques show that murine embryonic nuclear proteins specifically bind a 753-base pair (bp) DNA fragment from the region upstream of the Hox 1.5 homeo box. A fusion protein containing the Hox 1.5 homeo domain constructed in lambda gt11 also binds the same 753-bp DNA fragment. Specific binding of the fusion protein to the upstream ...

Phytoplankton Production In The Delaware Estuary: Temporal And Spatial Variation., Jonathan Pennock

School of Marine Science and Ocean Engineering

ABSTRACT:

Phytoplankton production in the Delaware Estuary (USA) was measured over several seasonal cycles (1980-1985). Seasonal variability in daily area1 production (JP; g C m-2 d-l) was dlrectly related to chlorophyll concentrations in the upper estuary, ranging from a maximum of 1.1 g C m-' d-' In summer to a minlmum of d-l) dunng summer in the presence of low phytoplankton biomass (2 to 10 kg Chl I-'), and in mid-estuary [2.6 g C d-l) during the spring diatom bloom (50 to 60 yg Chll-l). Desplte the occurrence of maximum nutnent concentrations in the freshwater region, highest JP ...


Management Measures For The Shark Bay Snapper Fishery 1987 Season., P. Millington Nov 1986

Management Measures For The Shark Bay Snapper Fishery 1987 Season., P. Millington

Fisheries management papers

The 1986 Shark Bay snapper fishing season mirrored in almost all respects the situation which will apply when the limited entry regime is put into effect. It was thus an opportunity to assess how effective the measures recommended in the Report of the Shark Bay Snapper Fishery Working Group were in reducing effort in the fishery.


The Esperance Rock Lobster Working Group Interim Report By The Chairman Mr. A. Pallot To The Western Australia Fishing Industry., A. Pallot Nov 1986

The Esperance Rock Lobster Working Group Interim Report By The Chairman Mr. A. Pallot To The Western Australia Fishing Industry., A. Pallot

Fisheries management papers

In July 1985 the Minister for Fisheries released a discussion paper titled "Arrangements for entry to all fisheries off and along the Western Australian coast" for consideration by all members of the fishing industry. The Australian Fishing Industry Council (W.A. Branch), now the Western Australian Fishing Industry Council (Inc), responded to the discussion paper in March 1986. The following were included in the Council's recommendations: 1. The rock lobster fishery near Esperance be a limited entry fishery. 2. The bench mark date for determining access by April 30, 1985. 3. that the Minister for fisheries establish a representative ...

Sequence Alignment With Matched Sections, Jerrold R. Griggs, Philip J. Hanlon, Michael S. Waterman

Faculty Publications

In molecular biology, two finite sequences are compared by displaying one sequence written over another in an alignment. The number of alignments of two sequences is related to the Stanton-Cowan numbers. This paper gives asymptotics for the number of alignments of two sequences of length n with matching sections of size at least b.


Chemical, Physical And Mineralogical Properties Of Mitchell And Tripp Soils In The Nebraska Panhandle, G. A. Uzochukwu, D. T. Lewis Oct 1986

Chemical, Physical And Mineralogical Properties Of Mitchell And Tripp Soils In The Nebraska Panhandle, G. A. Uzochukwu, D. T. Lewis

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Mitchell and Tripp soils are some of the most important agricultural soils in the Nebraska Panhandle. Yet, they have received little attention in terms of their basic chemical, physical, and mineral properties. Management decisions can be made on a more informed basis if this kind of information is available. This study was to acquire the information, with special emphasis on mineralogical properties of the soils and their parent materials. This emphasis was given because it is known that other soils in the region contain volcanic ash in measurable amounts. The presence of volcanic ash in soils has been associated with ...


The Report Of The Fish Farming Legislative Review Committee., P. Rogers Oct 1986

The Report Of The Fish Farming Legislative Review Committee., P. Rogers

Fisheries management papers

In 1975, amendments to the Fisheries Act provided for the licensing and control of commercial fish farming activities and , for specific declared species, further controls on their processing and marketing. To date, marron has been the only species to be declared a "farm fish". During the last decade, much of the State's aquaculture impetus has focused on marron although more recently greater attention has been directed towards trout, yabbies and freshwater aquarium fish species. On November 19, 1984, the Marron Growers Association of Western Australia (Inc) wrote to the Minister for Fisheries and Wildlife, seeding a general review of ...

National parks are created to preserve areas of special scenic and cultural value for enjoyment and use. Managing the parks in a manner that protects the important values and purposes for which they were created presents important and ...


Effects Of Corn Oil And Benzyl Acetate On Number And Size Of Azaserine-Induced Foci In The Pancreas Of Lew And F344 Rats, Daniel S. Longnecker, B D. Roebuck, Thomas J. Curphey, Evelyne Lhoste, Charles I. Coon, Denise Macmillan Sep 1986

Effects Of Corn Oil And Benzyl Acetate On Number And Size Of Azaserine-Induced Foci In The Pancreas Of Lew And F344 Rats, Daniel S. Longnecker, B D. Roebuck, Thomas J. Curphey, Evelyne Lhoste, Charles I. Coon, Denise Macmillan

Dartmouth Scholarship

The response of LEW and F344 strain rats to the pancreatic carcinogen azaserine was compared using the size and number of azaserine-induced acidophilic acinar cell foci and nodules as parameters in a 4-month experiment. A second experiment compared the effect of corn oil intake by gavage and dietary routes on the growth of azaserine-induced pancreatic lesions in LEW rats. A third experiment tested the activity of benzyl acetate in regard to its ability to induce acinar cell foci or to promote the growth of such foci in azaserine-treated rats. The results showed that equivalent doses of azaserine induce two to ...
