Amwa Endorses Uniform Mammography Screening, Mary Guinan

School of Public Health Faculty Research

Breast cancer is gaining on us at an increasing rate each year. In 1990 in the United States alone we expect about 145,000 new cases and 45,000 breast cancer deaths in women. What are we doing about it? What is AMWA doing, and what are women physicians doing- for themselves and their patients? Can we do anything? The answer is yes, we can. We can reduce mortality considerably if the cancer is detected early. The five-year survival rate for women with breast cancer diagnosed in its early (localized) stages is 90%, but for women with cancer diagnosed after it has …

Effects Of Sodium Intake, Furosemide, And Infusion Of Atrial Natriuretic Peptide On The Urinary And Metabolic Clearances Of Arginine Vasopressin In Normal Subjects, Arnold M. Moses, Carol Jones, Carolyn B. Yucha

Nursing Faculty Research

Arginine vasopressin (AVP) and atrial natriuretic peptide (ANP) have important influences on water and electrolyte metabolism, and studies on the interactions between these hormones may have important implications. We have investigated the effects of sodium intake, furosemide, and infusion of ANP on the urinary and metabolic (nonurinary) clearances of AVP in hydrated normal subjects. On a high sodium diet there was an increase in urine volume, sodium excretion, osmolal clearance, plasma ANP concentration, and urinary clearance and fractional excretion of AVP, with a decrease in PRA. The infusion of furosemide increased urine volume, sodium excretion, osmolal clearance, and PRA, but …

Sharing Memory In Distributed Systems, Oscar Rodrigo Aguilar

UNLV Retrospective Theses & Dissertations

We propose an algorithm for simulating atomic registers, test-and-set, fetch-and-add, and read-modify-write registers in a message passing system. The algorithm is fault tolerant and works correctly in presence of up to (N/2) -1 node failures where N is the number of processors in the system. The high resilience of the algorithm is obtained by using randomized consensus algorithms and a robust communication primitive. The use of this primitive allows a processor to exchange local information with a majority of processors in a consistent way, and therefore to take decisions safely. The simulator makes it possible to translate algorithms for the …

Government Land Management And The Free Market In Southern Nevada, William Robert Jacobs

UNLV Retrospective Theses & Dissertations

About 93.4 percent of the land area of southern Nevada is controlled by government agencies. The control of such a great amount of land may represent an impediment to the action of a free market in southern Nevada; The Bureau of Land Management (BLM) is the largest of several government land managers, consequently this paper concentrates on BLM regulations and practices. The BLM had little power until the passage of the Federal Land Policy and Management Act (FLPMA) of 1976; In addition to the FLPMA, four other laws have particular significance to BLM land management actions in southern Nevada: the …

The Income Gap And Symphony Orchestras, Joseph Anthony Volpi

UNLV Retrospective Theses & Dissertations

Symphony orchestras are the supposed victims of a malignant disease entitled "Baumol's Disease" which occurs as costs rise at a faster rate than earned income. The gap between earned income and costs is called the "Income Gap." The remedy is injections of cash to stop the disease from expanding; This thesis takes actual data from the American Symphony Orchestra League and tests Baumol's diagnosis. The income gap does exist and it is growing over time; To determine if the income gap is an incurable disease, a more comprehensive model is designed including output composition variables, demographic variables, and the lagged …

The Historical Origins Of The American Peace Test, David Leon Mann

UNLV Retrospective Theses & Dissertations

This thesis explains the historical origins of the anti-nuclear protest group, the American Peace Test (APT), which has focused its activities at the Nevada Test Site. This study concludes that interest in direct action was evident during the 1983-1984 Direct Action Framework Period within the Nuclear Weapons FREEZE Campaign. This interest became more tangible with a call to the Nevada Desert Experience (NDE) group in May of 1985 requesting to participate in an action. That interest was then amplified and validated at that August NDE action. The first APT action was then organized for October and November. At the Annual …

Design Of Deadlock Detection And Prevention Algorithms In Distributed Systems, Ramesh Dutt Javagal

UNLV Retrospective Theses & Dissertations

A distributed system consists of a collection of processes which communicate with each other by exchanging messages to achieve a common goal. One of the key problems in distributed systems is the possibility of deadlock. Processes are said to be deadlocked when some processes are blocked on resource requests that can never be satisfied unless drastic systems action is taken. Two distributed deadlock detection algorithms handling multiple outstanding requests is proposed and are proven to be correct: it detects all cycles and does not detect false deadlocks. The algorithms are based on the concept of chasing the edge of the …

Reaction Time And General Intellectual Ability: The Effects Of Cues On The Relationship, Nancy S Sirkin

UNLV Retrospective Theses & Dissertations

This study examined the relationship between reaction time (RT) and intelligence. Fifteen female and nine male caucasian undergraduates and one black male undergraduate ranging in age from 19 to 38 served as subjects. The measure of intelligence was the Otis-Quick Scoring Mental Ability Test. An Apple MacIntosh personal computer was used to present stimuli and measure reaction time. There were four RT conditions; simple reaction time, and three complex conditions in which no cue appeared, a correct cue, or an incorrect cue appeared. A significant correlation was found between the correct cue/no cue difference score (r = {dollar}-{dollar}.43, p {dollar}<{dollar}.05).

Measurement Of Thermal Energy Charge Transfer Rate Of Multiply Charged Molybdenum (Molybdenum(6+)) And Argon, Ying Jiang

UNLV Retrospective Theses & Dissertations

We have made the first measurement of the thermal energy charge transfer rate of Mo{dollar}\sp{6+}{dollar} and neutral argon. This measurement was carried out using a technique that combines the production of ions by laser ablation and an ion trap. The multiply charged ions produced by laser ablation are cooled by crossed beams collision. These ions are stored in a radio-frequency ion trap. The charge transfer rate is determined by measuring the rate of loss of stored ions in the trap. The charge transfer rate coefficient, k, of Mo{dollar}\sp{6+}{dollar} and Ar is 1.02(.10) {dollar}\times{dollar} 10{dollar}\sp{-10}{dollar}cm{dollar}\sp3{dollar}s{dollar}\sp{-1}{dollar}.
