Changes In Plant Variety Protection, Neil Harl Dec 1994

Changes In Plant Variety Protection, Neil Harl

Agricultural Law Digest

Since enactment in 1970, the Plant Variety Protection Act had received relatively little attention until the litigation relating to the "saved seed" exception commenced in 1991. That case, Asgrow Seed Co. v. Winterboer, is before the U.S. Supreme Court with a decision expected some time in 1995.

The Congress has now passed and the President has signed legislation amending the 1970 act which reverses, statutorily, the U.S. Court of Appeals decision in Asgrow Seed Co. v. Winterboer and makes several other changes in the Plant Variety Protection Act.

Agricultural And Food Policy Preferences: The 1994 Perspectives Of South Dakota Agricultural Producers, Bashir Qasmi, John A. Sondey Dec 1994

Agricultural And Food Policy Preferences: The 1994 Perspectives Of South Dakota Agricultural Producers, Bashir Qasmi, John A. Sondey

Economics Research Reports

U.S. farm policies are reviewed, every five years concurrent with the drafting of new farm legislation. The present farm bill expires in 1995, and a new bill will be debated and enacted in 1995. Since farm and food policies have a major impact on farmers, information on their preferences with regard to these policies are invaluable to legislators as well as to different advocacy groups (working for farmers). The research was completed as a part of a 15 state study to document the agricultural and food policy preferences by agricultural producers. This report deals with the policy preferences of ...

More On Related Party Sales, Neil Harl Dec 1994

More On Related Party Sales, Neil Harl

Agricultural Law Digest

In the April 29, 1994, Agricultural Law Digest, we examined the subject of related party sales with emphasis on the rules governing sales of depreciable property between related persons and related party sales where the buyer resells the property within two years. Because of the interest in the topic, particularly involving the sale of livestock held for breeding and dairy purposes, this article explores additional features of the general problem of related party sales.

Daughter Cells Of Saccharomyces Cerevisiae From Old Mothers Display A Reduced Life Span, Nicanor Austriaco, Brian K. Kennedy, Leonard Guarente Dec 1994

Daughter Cells Of Saccharomyces Cerevisiae From Old Mothers Display A Reduced Life Span, Nicanor Austriaco, Brian K. Kennedy, Leonard Guarente

Biology Department Faculty Publications

The yeast Saccharomyces cerevisiae typically divides asymmetrically to give a large mother cell and a smaller daughter cell. As mother cells become old, they enlarge and produce daughter cells that are larger than daughters derived from young mother cells. We found that occasional daughter cells were indistinguishable in size from their mothers, giving rise to a symmetric division. The frequency of symmetric divisions became greater as mother cells aged and reached a maximum occurrence of 30% in mothers undergoing their last cell division. Symmetric divisions occurred similarly in rad9 and ste12 mutants. Strikingly, daughters from old mothers, whether they arose ...


Pronominal Clitics In Québec Colloquial French: A Morphological Analysis, Julie Auger Dec 1994

Pronominal Clitics In Québec Colloquial French: A Morphological Analysis, Julie Auger

IRCS Technical Reports Series

The grammatical status of Romance pronominal clitics has long been the object of intense debate. Are they syntactically-independent arguments or are they affixal agreement markers? This dissertation addresses this question with respect to Québec Colloquial French (QCF). It treats the morphophonological and morphosyntactic dimensions as two independent dimensions, thus allowing either for affixes to have argument status and prohibiting them from co-occurring with an overt, lexical argument, or for non-affixal elements to behave like agreement markers and not count as syntactic arguments. The analysis reveals that all the clitics of QCF are affixes at the morphological level, since they demonstrate ...


Factors Influencing The Oxidation Of Lipoproteins And Plasma Lipids, Yanshan Ma Dec 1994

Factors Influencing The Oxidation Of Lipoproteins And Plasma Lipids, Yanshan Ma

Electronic Theses and Dissertations

The hypothesis that antioxidant vitamins (ascorbate and tocopherols) along with urate protect blood plasma lipids from oxidation was tested. Dietary fat is also an important factor influencing plasma lipid peroxidation. The purpose of this study was to investigate the role of plasma antioxidants and dietary fat on low density lipoprotein (LDL) and plasma lipid oxidation. In the first part of this study, we compared the ability of urate and ascorbate to protect human LDL from in vitro oxidation. LDL oxidation was initiated by 15 mM of a water soluble azo-initiator in the presence or absence of ascorbate or urate. The ...


Microcirculation: Electrophysiological Basis For The Response Of Endothelial Cells To Inflammatory Mediators-Bradykinin, Kai Miao Dec 1994

Microcirculation: Electrophysiological Basis For The Response Of Endothelial Cells To Inflammatory Mediators-Bradykinin, Kai Miao

Electronic Theses and Dissertations

Using conventional microelectrodes, I studied the electrical basis for determining the resting V$\sb{\rm m}$ in intact EC's from hamsters. The resting V$\sb{\rm m}$ were found to be $-$40 mV for aortic EC's and $-$43 mV for vena caval EC's. The contributions of ions to the resting V$\sb{\rm m}$ of aortic EC's were compared in terms of the transference number (t$\sb{\rm ion}$). To develop a technique for in situ monitoring changes in V$\sb{\rm m}$ of postcapillary venular EC's in the hamster mesentery, a voltage-sensitive fluorescent probe ...


Role Of The Cd40-Cd40 Ligand Interaction In Cd4(+) T Cell Activation Of Monocyte Interleukin-1 Synthesis, David H. Wagner Dec 1994

Role Of The Cd40-Cd40 Ligand Interaction In Cd4(+) T Cell Activation Of Monocyte Interleukin-1 Synthesis, David H. Wagner

Electronic Theses and Dissertations

Most studies of the induction of cytokine synthesis in monocytes have used an exogenous triggering agent such as Lipolpoysaccharide (LPS). However, during nonseptic chronic inflammatory responses (e.g., rheumatoid arthritis) monocyte activation occurs as a result of T cell generated signals. This report demonstrated that plasma membranes from anti-CD3 activated peripheral CD4$\sp{+}$ T cells (Tm$\sp{\rm A}$) but not from resting CD4$\sp{+}$ cells (Tm$\sp{\rm R}$) induced monocytes to synthesize IL-1 in the absence of costimulatory cytokines. The expression kinetics of the molecule(s) unique to activated T cells which interact with monocyte receptors to induce ...

The Effects Of Elevated Glucose Upon Na+/K+-Atpase In Bovine Retinal Pigment Epithelial Cells, Julie Y. Crider

Theses and Dissertations

Crider, Julie Y., The Effects of Elevated Glucose Upon Na+/K+-ATPase in Bovine Retinal Pigment Epithelial Cells. Doctor of Philosophy (Biomedical Sciences, Pharmacology), December, 1994, 154 pp., 14 tables, 31 illustrations, bibliography, 288 titles. Bovine retinal pigment epithelial (RPE) cells were cultured under 1, 4.5 and 10 g/l glucose conditions in order to characterize the effects of hyperglycemia upon Na+/K+-ATPase. Functional activity of Na+/K+-ATPase was measured as ouabain-sensitive Rb+ uptake. 3H ouabain was used to assess binding characteristics of Na+/K+-ATPase. The major contributors to rubidium (mRb+) uptake activity were the ouabain-sensitive ...

Research Report No. 32, Trends Of Non-Straight Tree Stems In Loblolly And Slash Pine Plantations In East Texas, 1985-1994, H. Alexis Ross, J. David Lenhart Dec 1994

Research Report No. 32, Trends Of Non-Straight Tree Stems In Loblolly And Slash Pine Plantations In East Texas, 1985-1994, H. Alexis Ross, J. David Lenhart

Informal Project Reports

Trees from East Texas loblolly ( Pinus taeda L. ) and slash ( Pinus effiottii Engelm. ) pine plantations are one of the sources of raw material for conversion into products such as paper, veneer and lumber by East Texas forest product mills. The utilization of the planted trees may depend on various biological and economical factors. Factors such as tree size, tree condition, stumpage prices and interest rates can play a role in the merchandizing process.

One of the factors, tree condition, may be affected by tree crown position in canopy, incidence of disease, single stem and straightness of stem. Trees with straighter ...


Cage Culture Of Fish In The North Central Region, Ladon Swann, Joseph E. Morris, Dan Selock, Jean Rosscup Riepe Dec 1994

Cage Culture Of Fish In The North Central Region, Ladon Swann, Joseph E. Morris, Dan Selock, Jean Rosscup Riepe

NCRAC Technical Bulletins

The commercial production of fish is most commonly performed in open ponds, raceways, water reuse systems, and cages. Cage culture of fish is an intensive production method that allows the farmer to utilize existing farm ponds, borrow pits, or strip pits normally unsuitable for open pond culture, by enclosing fish in cages or pens. Generally, yields (pounds/acre) are greater in open pond culture. However, there are times when existing bodies of water do not lend themselves to open pond culture and cage culture may be the best alternative.

Procedures For The Administration And Assessment Of Clearing And Protection Of Native Vegetation In Western Australia, Alexander Mcrae Holm Dec 1994

Procedures For The Administration And Assessment Of Clearing And Protection Of Native Vegetation In Western Australia, Alexander Mcrae Holm

Soil conservation survey collection

It is Department of Agriculture policy that regulation is only used when all other approaches to address land degradation have failed. Our thrust is to encourage land holders to move towards using land within its capabilities as they continue to adopt sustainable farming systems. Underlying this approach is a self regulatory philosophy with land conservation district committees playing an important management and coordination role. Nevertheless the community expects that land degradation will be controlled and legislation is available to underpin or complement the good intentions of most land holders. The Soil and Land Conservation Act is the legislation used to ...


Characterization Of General Esterases From Susceptible And Parathion-Resistant Strains Of The Greenbug (Homoptera: Aphididae), Midori Ono, Jonathan S. Richman, Blair Siegfried Dec 1994

Characterization Of General Esterases From Susceptible And Parathion-Resistant Strains Of The Greenbug (Homoptera: Aphididae), Midori Ono, Jonathan S. Richman, Blair Siegfried

Faculty Publications: Department of Entomology

A susceptible and two parathion-resistant strains of the greenbug, Schizaphis graminum (Rondani), exhibit three different patterns of general esterase isozymes in native polyacrylamide electrophoresis gels. Characterization of general esterase activity using α -naphtholic esters as model substrates indicated that the three strains differed in isozyme composition. The type-I1 strain, which had the highest level of resistance, exhibited the highest levels of general esterase activity under all assay conditions, and the type-I strain had consistently higher levels than the susceptible strain. In all three strains, these esterases were more active toward α -naphtholic esters with side chains of six or fewer ...

Host Specificity Of Rhabdochona Canadensis (Nematoda: Rhabdochonidae) In Nebraska, Michael A. Barger, John J. Janovy Jr. Dec 1994

Host Specificity Of Rhabdochona Canadensis (Nematoda: Rhabdochonidae) In Nebraska, Michael A. Barger, John J. Janovy Jr.

John Janovy Publications

Intermediate and definitive host specificity of Rhabdochona canadensis in Nebraska were investigated. Mayfly nymphs Trichorythodes sp. and Caenis sp. were found to serve as experimental intermediate hosts. Development inside the nymphs required approximately 10 days, with the worms passing through two molts and then becoming encapsulated in the hemocoel as infective third-stage juveniles. Survey data revealed that only the red shiner Cyprinella lutrensis serves as definitive host for R. canadensis in nature. Laboratory infections of Notropis dorsalis, N. stramineus, and Fundulus zebrinus. all of which were uninfected in nature, were attempted to determine if observed specificity was due to physiological ...


Second Intermediate Host-Specificity Of Haematoloechus Complexus And Haematoloechus Medioplexus (Digenea: Haematoloechidae), Scott D. Snyder, John J. Janovy Jr. Dec 1994

Second Intermediate Host-Specificity Of Haematoloechus Complexus And Haematoloechus Medioplexus (Digenea: Haematoloechidae), Scott D. Snyder, John J. Janovy Jr.

John Janovy Publications

Second intermediate host-specificity was examined for two species of the frog lung fluke genus Haematoloechus. Nine species of freshwater arthropods were exposed to cercariae of H. complexus and H. medioplexus. Metacercariae of H. complexus developed in all arthropod species used. Metacercariae of H. medioplexus developed only in anisopteran odonate naiads. This difference in host utilization may have epizootiological implications. The potential development of H. complexus in a greater number of arthropods than H. medioplexus may increase the chances of ingestion of H. complexus by an anuran host. The range of arthropods parasitized by H. complexus indicates that host-specificity of the ...

Fall Field Report, August-November 1994, W. Ross Silcock, Richard C. Rosche Dec 1994

Fall Field Report, August-November 1994, W. Ross Silcock, Richard C. Rosche

Nebraska Bird Review

The fall season is a long one in terms of bird movements. The SUMMER FIELD REPORT detailed the post-breeding wanderings of herons and the beginning of shorebird migration. This report covers the end of these and the southward movements of insectivorous passerines, mainly in August and September, while seedeaters such as sparrows follow, mainly in September and October. Waterfowl generally bring up the rear, moving south just ahead of the freeze-up.

The fall season is probably the most exciting time for rare bird enthusiasts, as young birds of many species wander, often aimlessly, at this time of year before they ...

"Notes On Bird Sightings In Nebraska," From Nebraska Bird Review (December 1994)

Nebraska Bird Review

Northern Waterthrush. At 9:35 a.m. on December 14, and again at 10:15 a.m. on December 21, 1994, I observed what I believe was the same bird on a Burlington Northern railroad embankment north of Gifford Road in Fontenelle Forest, Bellevue, NE. On December 14, I saw it for 7 seconds. It vocalized with a sharp "chink" as it hopped up on a fallen log, then vocalized again 6-7 seconds later as it jumped down into thick underbrush. It was silent on December 21, but I observed it for at least ten minutes as it walked at ...
