The Effects Of Bilateral Injections Of Neuropeptide K Into The Medial Preoptic Area On Male Rat Copulatory Behavior, Peter Malen '91 May 1991

The Effects Of Bilateral Injections Of Neuropeptide K Into The Medial Preoptic Area On Male Rat Copulatory Behavior, Peter Malen '91

Honors Projects

The first mammalian neuropeptide to be characterized was substance P (sP) , and it is now recognized that sP is a member of a structurally related family of peptides, the tachykinins. Extensive studies have demonstrated. that sP and some related tachykinin peptides play key roles as neurotransmitters and neuromodulators. The synthesis of different members of the tachykinin family is in part due to the modifications' of three sP-encoding preprotachykinin (PPT) mRNA's that are derived from a single sP gene. At least four tachykinin peptides can be synthesized as a result of these differential modifications including sP, neurokinin A, neuropeptide and …

Intracerebral Injections Of Substance P Fragments (5-11) And (1-7) Into The Dorsal Midbrain Central Gray Have No Effects On Lordosis Behavior In The Female Rat, Jodi K. Block '91 May 1991

Intracerebral Injections Of Substance P Fragments (5-11) And (1-7) Into The Dorsal Midbrain Central Gray Have No Effects On Lordosis Behavior In The Female Rat, Jodi K. Block '91

Honors Projects

Substance P (sP), a neuroactive peptide, has now been implicated in a wide range of behaviors. One in particular is female rat sexual behavior. Recently, it has been shown that bilateral injections of sP into the dorsal midbrain central gray (dMCG) of estrogen-primed female rats facilitate sexual behavior (lordosis). Uncertainty remains, however, concerning the mode of action of synaptically released sP. Indeed, most of our understanding of sP activity has revealed that its full structural sequence is not needed for biological activity. This has led to speculation that sP may be processed into one or more types of fragments before …


Effect Of Straw On The Behaviour Of Growing Pigs, David Fraser, P. A. Phillips, B. K. Thompson, T. Tennessen May 1991

Effect Of Straw On The Behaviour Of Growing Pigs, David Fraser, P. A. Phillips, B. K. Thompson, T. Tennessen

Social Behavior Collection

The effects of straw on the behaviour of young growing pigs were studied in two experiments. In Experiment 1, group of three pigs, aged about 7 weeks, were housed in raised decks with or without straw bedding. Time-lapse video recording showed no major differences between treatments in the amount or daily pattern of overall activity and feeding. Detailed observations showed that bedding reduced the incidence of rooting and chewing on pen-mates, but had little effect on other social activities such as mounting and aggressive biting. Experiment 2 compared groups of eight growing pigs aged about 10 weeks, housed in floor …

On The Relationship Between Parsimonious Covering And Boolean Minimization, Venu Dasigi, Krishnaprasad Thirunarayan May 1991

On The Relationship Between Parsimonious Covering And Boolean Minimization, Venu Dasigi, Krishnaprasad Thirunarayan

Kno.e.sis Publications

Minimization of Boolean switching functions is a basic problem in the design of logic circuits. The designer first comes up with a switching function expressed in terms of several binary input variables that satisfies the desired functionality, and then attempts to minimize the function as a sum of products or product of sums. It turns out that a sum of products form of a switching function that has no redundancy is a union of prime implicants of the function.

In this paper we would like to explicate some of the relationships of the boolean minimization problem to a formalization of …


Hazard Perception And Preparation By Cross-Country Skiers In Utah, Kevin J. Kobe May 1991

Hazard Perception And Preparation By Cross-Country Skiers In Utah, Kevin J. Kobe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis examined how cross-country skiers perceive and prepare for winter hazards. A self-completion questionnaire was administered to cross-country skiers in northern Utah. The questions on the questionnaire were designed to explore the relationships that affect how skiers perceive and prepare for winter hazards. Additionally, the situation where skiers put themselves at risk due to lack of information as opposed to skiers placing themselves at risk through the desire to confront nature's dangers was explored. Variables that were contained in these relationships were correlated and the degree of correlation was measured.

Those that sought information on the day surveyed were …


An Assessment Of Behavior Associated With Reproduction And Infant Caretaking In A Captive Family Group Of Saguinus Midas Midas, Melissa Elizabeth Martenson Apr 1991

An Assessment Of Behavior Associated With Reproduction And Infant Caretaking In A Captive Family Group Of Saguinus Midas Midas, Melissa Elizabeth Martenson

Dissertations and Theses

The present study gathered both general and specific information about the behavior of a captive family group of Saguinus midas midas [red-handed tamarins] housed at the Washington Park Zoo, Portland, Oregon, USA. Saquinus midas midas is a rarely studied species, and detailed information about the behavior of this species is virtually nonexistent. For this reason, this study collected information about both activity budgets and social grouping within this family group.

The primary focus of this study was, however, the socialization of captive juvenile tamarins with respect to several behaviors relevant to reproductive success among the Callitrichidae. The behaviors assessed were: …

Describing The Flora Of The United States: Botanies At Libraries In Syracuse, Dudley J. Raynal Apr 1991

Describing The Flora Of The United States: Botanies At Libraries In Syracuse, Dudley J. Raynal

The Courier

The first written descriptions of the flora of North America were those of sixteenth-century Europeans who marvelled at the botanical treasures brought to them by explorers of the New World. The earliest account of American natural history was that of the English botanical explorer Thomas Hariot who wrote his Briefe and True Re, port of the New Found Land of Virginia in 1590 after returning from an expedition arranged by Sir Walter Raleigh. Hariot carried to En, gland tubers, fruits, and seeds of plants previously unknown in Europe. Perhaps thirty different plant species had been introduced into Europe from the …

On Serializability Of Multidatabase Transactions Through Forced Local Conflict, Dimitrios Georgakopoulos, Marek Rusinkiewicz, Amit P. Sheth Apr 1991

On Serializability Of Multidatabase Transactions Through Forced Local Conflict, Dimitrios Georgakopoulos, Marek Rusinkiewicz, Amit P. Sheth

Kno.e.sis Publications

The main difficulty in enforcing global serializability in a multidatabase environment lies in resolving indirect transitive conflicts between multidatabase transactions. Indirect conflicts introduced by local transactions are difficult to resolve because the behavior or even the existence of local transactions is not known to the multidatabase system. To overcome these problems, we propose to incorporate additional data manipulation operations in the subtransactions of each multidatabase transaction. We show that if these operations create direct conflicts between subtransactions at each participating local database system, indirect conflicts can be resolved even if the multidatabase system is not aware of their existence. Based …


Effects Of Phenobarbital In Combination With Phenytoin Or Valproic Acid On The Delayed-Matching-To-Sample Performance Of Pigeons, Catherine Ann Karas Apr 1991

Effects Of Phenobarbital In Combination With Phenytoin Or Valproic Acid On The Delayed-Matching-To-Sample Performance Of Pigeons, Catherine Ann Karas

Masters Theses

The present study examined the effects of phenobarbital (S, 10,20, and 40 mg/kg), phenytoin (2.5, 5, 7.5, and 15 mg/kg), and valproic acid (40, 60, 80, and 120 mg/kg), and those of phenobarbital (10 and 20 mg/kg) in combination with phenytoin (2.5,5, and 7.5 mg/kg) or valproic acid (40, 60, and 80 mg/kg), on the delayed-matching-to-sample performance of pigeons. In general, high doses of each individual drug reduced accuracy. Drug combinations also reduced accuracy relative to control values. Reductions in accuracy produced by drug combinations were very similar in magnitude to those predicted by a response-addition model of drug interaction.

Review Of Colorado Flora: Eastern Slope By William A. Weber., Robert B. Kaul Feb 1991

Review Of Colorado Flora: Eastern Slope By William A. Weber., Robert B. Kaul

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

All 2260 plant species of eastern-slope Colorado--from the continental divide east to the Nebraska and Kansas borders--can be identified using this book. That figure includes not only the native species but also the numerous introduced ones that survive without cultivation and often provide severe competition for the native flora. Much of Colorado's native plains flora was eliminated in the past century by plowing and by grazing livestock. It is largely replaced by a few durable native and many aggressive exotic species that thrive under those conditions, but remnants of the original flora exist on escarpments and in a few level …

Studies Of The Precambrian Geology Of Iowa: Part 2. The Matlock Keratophyre, Kenneth E. Windom, Karl E. Seifert, Raymond R. Anderson Jan 1991

Studies Of The Precambrian Geology Of Iowa: Part 2. The Matlock Keratophyre, Kenneth E. Windom, Karl E. Seifert, Raymond R. Anderson

Journal of the Iowa Academy of Science: JIAS

Felsic pyroclastic rock occurs in the Precambrian basement in northwestern Iowa. This rock was recovered by drilling and originally logged as rhyolite; however it is severely depleted in K2O, Rb, Ba, Cs, and other mobile elements and is more properly called keratophyre. The volcanic unit lies atop a layered mafic/ultramafic complex and contains xenoliths of gabbro apparently derived from the layered body. These xenoliths are severely altered and are composed of secondary hydrated and carbonated minerals. The gabbros are enriched in incompatible trace elements, whose abundance patterns complement those of the keratophyre. Trace element abundance patterns for the …

In Search Of A Gibberellin Receptor, Lalit M. Srivastava, Konrad A. Sechley

Journal of the Iowa Academy of Science: JIAS

Use of tritiated gibberellins ([3H] GA1, [3H] GA4) of high specific activity and purity has allowed the determination of GA-specific binding sites in several plant tissues both in vivo and in vitro. In cucumber hypocotyls and pea epicotyls which have been most investigated the binding of [3H] GA; occurs to soluble proteins. This binding is saturable ('n' =about 30 pmol. Mg-1 soluble protein), of high affinity (KD= about 70 nM), and is competed for by other GA, and derivatives in proportion to their biological activity in these …
