The Cardiovascular Response to Acute Hypoxic Conditions in Danio rerio

There are many fish that can withstand hypoxia levels. One in particular is the zebrafish (Danio rerio). The zebrafish is a small-sized, Cyprinid teleost fish, and has been used in a laboratory setting for many reasons. A few reasons being that they are widely available, easy to care for, and the cost for these fish are very low. There are various reasons why these fish are used as a model. One main reason is because their cardiovascular system is one of the first developing organs. This allows for better resolution when studying the cardiovascular system. The purpose of this study is to investigate the cardiovascular system of danio rerio during low oxygen conditions, and to investigate the cardiac response when Pcrit is reached. It is hypothesized that cardiac response will increase during the hypoxic conditions. This is because acute bouts of hypoxia are more stressful and cause more physiological impairment, than low O2 environments. A response will be much more apparent in embryonic zebrafish in stressful conditions. This stress response will be seen when normal heart rate, cardiac output, and stroke volume change

Simulation of the channelling of ions from MeV C60 in crystalline solids

Simulations were performed describing the motion and breakup of energetic C60 ions interacting with crystalline targets. A hybrid algorithm was used that employs a binary collision model for the scattering of the carbon ions by the atoms of the solid, and molecular dynamics for the Coulomb interactions of the 60 carbon ions with one another. For the case of yttrium iron garnet (YIG), directions such as [1 1 0], [1 0 0], [0 1 0] and [0 0 1] demonstrate channelling for a large fraction of the C ions. For directions such as [1 1 1], [2 1 1] and [7 5 3] the trajectories show no more channelling than for random directions. The effects of tilt, shielding and wake-field interactions were investigated for YIG and α-quartz

Articulating Value of Archaeological Resources After Damage, Archaeological Crime and the Archaeological Resources Protection Act

Archaeological crime is pervasive in the United States and throughout the world. While laws in the United States do not vest national ownership rights in archaeological resources, there are stringent means to enforce federal property rights in cultural resources that exist on federal lands under the Archaeological Resources Protection Act (ARPA) as well as the Embezzlement and Theft, and Malicious Mischief federal statutes. In order to exercise these rights, federal land managers and archaeologists must know how to proceed upon detection of an archaeological violation. Specifically, there must be a thorough understanding of how to prepare an adequate archaeological damage assessment report that addresses the value of the archaeological resources and the consequent loss from the damage to them so that a judge and potential jury sufficiently appreciate the valuable yet irretrievable nature of archaeological resources. An adequately prepared archaeological damage assessment report is paramount to the concept of archaeological value and demonstrating the loss to this value in the court system, and consequently the public. This model, having established its potential effectiveness when properly followed, can and should be used in all archaeological crime cases implicating not only federal, but state, private, and international jurisdictions, and employing any archaeological protection statutes. After a brief history of the case law that defined the parameters of ARPA and its implementing regulations, this paper will discuss details of permitting procedures and preparing an adequate archaeological damage assessment report, including the inconsistencies in damaged site recordation that lead to common mistakes and pitfalls in documentation and report preparation. I also provide an in depth discussion of the concept of archaeological value, how it is established under ARPA, the implementing regulations, and case law. This paper will provide guidance to those who wish to better utilize ARPA and other archaeological protection laws to detect, document, and ultimately prosecute archaeological resource crimes more effectively and deter archaeological crime in the United States and abroad

Reproductive Parameters and Methodologies for the Culture of Golden Topminnows (Fundulus chrysotus) and Bluenose Shiners (Pteronotropis welaka)

The global ornamental fish trade has expanded over the past 20 years, requiring captive rearing methods to be improved or developed for species of interest. Aquaculture of desirable species is preferable over wild harvest to conserve natural habitats and biodiversity. This thesis focused on improving culture methods for Golden Topminnows Fundulus chrysotus and developing culture methods for Bluenose Shiners Pteronotropis welaka, both native fishes of the southeastern United States with ornamental demand. A combination of reproductive metric analyses, examination of historical collections, and captive spawning trials were employed to target specific objectives for each species. In female Golden Topminnows, they appear to conserve the energy invested towards reproduction, as the yolk volume of embryos and egg gram-1 fecundity did not differ between female size classes. This nondifferentiated reproductive investment, coupled with decreased survival to hatch and smaller total length of larvae at hatch indicate stocking greater quantities of small or medium Golden Topminnows may increase production. Improved incubation methods could prevent potentially hypoxic conditions that may have led to inhibited embryonic development observed in the current study. Historical collections of Bluenose Shiners displayed distinct sexual dimorphism, especially in anal and dorsal fin lengths when their total length exceeds 45 mm. Results of gonadosomatic index and gonad histology analyses indicated a peak in maturity and supposed spawning between mid-May and early-June. Captive spawning of Bluenose Shiners was unsuccessful using natural environmental cues and/or hormone injections. However, the methods employed herein can guide future attempts, as temperature and photoperiod were likely successful at inducing gonadal maturation, but improper timing or presentation of nest-associate cues for gamete release may have led to the unsuccessful attempts in the current study. Golden Topminnows require further examination of stocking density impacts on egg production and larval survival, while Bluenose Shiners should be further used in captive spawning studies to determine what cue of their nest-associate is necessary to induce spawning

The Manhattan Project legacy : low level radioactive waste health effects, an epidemiological study

An epidemiological survey was performed that included the area surrounding a former Department of Energy thorium processing and disposal facility. This facility processed monazite sands to obtain thorium under Federal Government contracts from 1941-1973. New Jersey Department of Environmental Protection radiological surveys had shown elevated radiation levels at the Site and in the vicinity of the plant. The area was divided into sections according to distance from the site and from Sheffield Brook, which is also contaminated. Questionnaires were mailed to 400 families, with 112 responses. These represent 362 people. Statistical analysis of the accumulated data regarding lifestyle, occupation, reproductive history, cancer and other disease states was performed. No significant increase in cancer, miscarriage or any other disease included in the survey was found. While not statistically significant, liver diseases other than cancer are more prevalent in all case groups. The reported jaundice rate is also higher. The rate of birth defects is also greater for those living closer to the site. The leukemia rate is also increased. An aggregation of disease incidence is apparent in the study area, and is of interest for further investigation
