Exhaust cloud rise and diffusion in the atmosphere

Analytical approach develops physical-mathematical model of rocket engine exhaust cloud rise, growth, and diffusion. Analytic derivations and resultant model apply to hot exhaust cloud study or industrial stack plumes, making work results applicable to air pollution. Model formulations apply to all exhaust cloud types and various atmospheric conditions

Life History, Diet, Abundance and Distribution, and Length-Frequencies of Selected Invertebrates in Florida Bay, Everglades National Park, Florida

This report presents information on the life history, diet, abundance and distribution, and length-frequency distributions of five invertebrates in Florida Bay, Everglades National Park. Collections were made with an otter trawl in basins on a bi-monthly basis. Non-parametric statistics were used to test spatial and temporal differences in the abundance of invertebrates when numbers were appropriate (i. e., $25). Invertebrate species are presented in four sections. The sections on Life History, and Diet were derived from the literature. The section on Abundance and Distribution consists of data from otter-trawl collections. In addition, comparisons with other studies are included here following our results. The section on Length-frequency Distributions consists of length measurements from all collections, except 1984-1985 when no measurements were taken. Length-frequency distributions were used, when possible, to estimate life stage captured, spawning times, recruitment into Florida Bay for those species which spawn outside the Bay, and growth. Additional material from the literature was added when appropriate. (PDF contains 39 pages

Population characteristics of a white-tailed deer herd in a bottomland hardwood forest of south-central Louisiana

White-tailed deer are an important economic and recreational resource in Louisiana. A basic understanding of population dynamics is essential to ensure sound management, but baseline information in Louisiana is lacking. Likewise, the notion of Quality Deer Management (QDM) continues to gain momentum in Louisiana. Our objectives were to evaluate space use, survival, and mortality for a deer herd managed under a QDM regime in south Louisiana. We captured 65 deer in West Baton Rouge and Iberville Parishes during 2007 and 2008, radio-marked 37 males and 11 females, and ear-marked an additional 10 males and 7 females. Home ranges (95%) for adult males during spring, summer, and fall were 153.9, 70.4, and 118.0 ha, respectively and were 119% and 68% larger during spring and fall than summer. Female home ranges were 67.3, 53.9, and 25.2 ha during spring, summer, and fall, respectively. Juvenile (1.5 yr-old) males increased space use 169% in spring (231.6 ha) relative to summer (86.1 ha), and maintained 50% larger home ranges than adults in spring. Survival estimates for adult males during spring, summer, and fall were 100, 95, and 55%, respectively. Mean annual survival for adult males was 53%. No mortalities were observed in spring or summer for 1.5 yr-old males, but ear-tag returns and harvest records indicated 1.5 yr-old males were being harvested at a rate approaching 20%. Mean annual mortality rates from harvest (40%) were greater than for non-harvest sources of mortality (16%). Non-hunting mortality included both natural causes (9%) and deer-vehicle-collisions (9%). We observed smaller home ranges than anticipated or seen previously, suggesting that landowners managing small (\u3c300 ha) tracts of property may be able to practice QDM at scales thought to be ineffective at improving herd dynamics. Due to low non-hunting mortality, young males (≤2.5-yr) are likely to survive to the next age class if protected from harvest, but ultimately have a small chance of reaching maturity (5.5+) because males are generally harvested as they approach the antler restriction in place. Managers should seek to increase fall survival for males if management objectives include increasing the frequency of harvesting males ≥3.5 yrs-old

Trust Receipts

A note published in 1927 expressed the hope that the course of legal development in the state of Washington would result in recognition of the trust receipt as an\u27 instrument sui generis, perfectly effective within its limits. Recent doubts as to the fulfilment of this hope make it desirable to examine the question more closely. The purpose of the present paper therefore is to inquire into the function of the trust receipt as an instrument of the law merchant, and to determine if possible how that function may be most satisfactorily exercised under existing conditions

Realities of Independence and Development in Southeast Asia

Although it is not necessary for our purposes to go back to the earliest times which have been mentioned, it is impossible to understand properly the realities of the present and the pos­sibilities of the future expansion and decline of the English and Dutch East India Companies, and the second extends from that point into the twentieth century
