The Characterization of Underwater Infrasound Generated by Vibratory Pile Driving Within the Context of the Characteristics of Sound Known to Result in Avoidance Response by Juvenile Salmonids
No full textLittle data exists to document the nature of sound generated by vibratory pile driving and the response salmon to that sound. The construction of a new pier at Oregon State University's Hatfield Marine Science Center in 1996 offered the opportunity to monitor the sound. The findings were then related to known results of studies on salmonid response to sound. The author concludes that avoidance behavior is unlikely

LA 497C: Greenway Planning Studio - Undergraduate Program
Department of Landscape Architecture and Regional Planning
University of Massachusetts Amherst
Senior Students guided by: Professors Robert L. Ryan, Peter A. Kumble and Teaching Assistant: Kate Tooke
This is one of five reports submitted for the LA497C Spring 2011 Senior Studio project. The purpose of this report is to show the results of a partnership between the Town of Hatfield Massachusetts, and the Department of Landscape Architecture and Regional Planning at the University of Massachusetts. The Town of Hatfield initially approached the University for assistance in understanding the options available for Greenway development in Hatfield, while maintaining the charm and character the town is proud of. In his ground-breaking book, Greenways for America, Author Charles Little (1990) provides a simple definition of a Greenway: “A greenway is a linear open space established along either a natural corridor, such as a riverfront, stream valley, or ridgeline, or overland along a railroad right-of-way converted to recreational use, a canal, scenic road, or other route. It is any natural or landscaped course for pedestrian or bicycle passage. An open-space connector linking parks, nature reserves, cultural features, or historic sites with each other and with populated areas.” This report will provide an assessment and analysis of the current conditions of the Town of Hatfield and recommendations for a Greenway Plan that with enhance the quality of life for the residents
Observations on the circumstances producing ignition in charcoal in atmospheric temperatures
No full textThis article, written by Mr William Hatfield, abridged from the London and Edinburgh Philosophical Magazine for July 1833, details observations and experiments concerning the phenomenon of spontaneous combustion in charcoal at atmospheric temperatures. The author highlights the serious safety and property risks posed by this occurrence, particularly in settings such as gunpowder factories where large quantities of charcoal are used.
Hatfield notes that spontaneous combustion is most common when large quantities of charcoal, especially in a state of minute division (pulverised or small fragments), are gathered in heaps. While manufacturers often attribute this phenomenon to insufficient cooling after production, the author provides anecdotal evidence of ignition occurring in charcoal that had been made and freely exposed to the atmosphere for several days. Two specific accidental cases are described: one where a large, compressed load ignited during transport, and another where a large heap of pulverised, multi-day-old charcoal ignited in a storage building, leading to a fire.
The author hypothesises that in transport/storage incidents, the pressure and friction from pieces rubbing together cause pulverisation, creating a compact mass at the bottom, which is prone to self-heating.
Hatfield describes a series of direct experiments (Exp. 1-4) to investigate the cause:
Experiments 1-3 used small quantities (120 lbs) of charcoal (old, fresh, and coarse powder) in a barrel. These trials showed a temporary temperature increase (up to 130∘F) followed by a decline to ambient temperature, confirming that small quantities do not spontaneously combust.
Experiment 4 used a larger quantity (10 cwt or 1,000 lbs) of finely ground, new charcoal in a hogshead. The internal temperature steadily rose from 65∘F to 180∘ or 190∘F, at which point combustion occurred internally, surprisingly near the surface.
A final observation details a large heap of small charcoal igniting in several places over three to seven days, even after being soaked with water, reinforcing the persistent danger. The article concludes that the degree of pulverisation and the sheer quantity/volume of the charcoal are key factors in producing ignition.

Pharmacokinetics and toxic effects of lithium chloride after intravenous administration in conscious horses
No full textTwenty 3-mmol boluses of LiCl (0.15 mmol/l) were injected IV into healthy Standardbred horses (n=6) at 3-min intervals (60 mmol/horse total dose) during a 1-h period. Blood samples for measurement of serum lithium concentrations were collected before injection and up to 24 h after injection. Behavioural and systemic toxic effects of LiCl were assessed. Lithium elimination could best be described by a 3-compartment model for 5 of the 6 horses. Mean peak serum concentration was 0.561 mmol/l (range of 0.529-0.613 mmol/l), with an actual measured mean serum value of 0.575 mmol/l (range of 0.52-0.67 mmol/l) at 2.5 min after administration of the last bolus. Half life was 43.5 h (range of 32-84 h), and after 24 h, mean serum lithium concentration was 0.13+or-0.05 mmol/l (range of 0.07-0.21 mmol/l). The 60-mmol dose of LiCl did not produce significant differences in any measured haematologic or biochemical variables, gastrointestinal motility, or ECG variables evaluated during the study period. Distribution of lithium best fits a 3-compartment model, and clearance of the electrolyte was slow. Healthy horses remained unaffected by LiCl at doses that exceeded those required for determination of cardiac output. Peak serum concentrations were less than steadystate serum concentrations that reportedly cause toxic effects in other species..RE: 27 ref.; RN: 7447-41-8; SC: 0I; 0V; ZA; VE; CASource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0002-9645&isbn=&volume=62&issue=9&spage=1387&pages=1387-1392&date=2001&title=American%20Journal%20of%20Veterinary%20Research&atitle=Pharmacokinetics%20and%20toxic%20effects%20of%20lithium%20chloride%20after%20intravenous%20administration%20in%20conscious%20horses.&aulast=Hatfield&pid=%3Cauthor%3EHatfield%2c%20C%20L%3bMcDonell%2c%20W%20N%3bLemke%2c%20K%20A%3bBlack%2c%20W%20D%3C%2Fauthor%3E%3CAN%3E20013139438%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3
The development of self-criticism and the effects of self-compassion and mindfulness on the well-being of mothers
No full textThis research thesis main focus was examining parental factors in the
development of self-criticism in young people and role of mindfulness,
self-compassion and compassion to others, play in the psychological
well-being of mothers.
Chapter one is a literature review of twelve empirical studies exploring the
role of parental factors in the development of self-criticism in young
people. The findings from this review show an association between
parental self-critical personality style and parenting behaviours, which in
turn are associated with levels of self-criticism in their offspring. This
review highlights the potential importance of parent and carer
interventions aimed at modifying the parents’ and children’s self-critical
behaviours and attitudes. The literature review has been prepared for
submission to the Clinical Psychology Review (see Appendix A,‘Guide for
Authors’).
Chapter two is a quantitative, empirical study. The study explored maternal
levels of mindfulness, self-compassion, and compassion to others; and
their association with psychological well-being and parental stress.
Mothers were invited to participate via the internet and completed
questionnaires on-line. Higher levels self-compassion and mindfulness
were found to predict maternal psychological well-being and lower levels of
maternal stress. Clinical implications and areas for future research are
discussed alongside methodological limitations. The empirical study has
been prepared for submission to Self and Identity (see Appendix A, ‘Guide
for Authors’).
Chapter three is a reflective account of the research thesis as a whole. The
paper’s focus is on the importance of reflection, self-compassion and
mindfulness on personal and professional development. Methodological
issues arising from conducting quantitative research are discussed. This
paper has not been prepared for publication
