Development of a flexible MAPMT photon-counting read-out system
No full textThe design and the attained performances of a read-out system for a 64-channel Hamamatsu Multi Anode Photo Multipliers (MAPMT) are discussed. The system has been developed in the framework of the Extreme Universe Space Observatory (EUSO) experiment. EUSO is a space telescope devoted to the study of the ultra-high-energy cosmic rays, proposed for accommodation on board the International Space Station (ISS). This paper reports the tests on the read-out system and the optimization of its main parameters. A quick overview of some other possible applications of the system is also given

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
A review of "Fire in the Dark: Essays on Pascal���s Pens��es and Provinciales." by Charles M. Natoli
No full textA large area MicroGap chamber with two-dimensional read-out
No full textA 10x10 cm(2) MicroGap Chamber with a small stereo angle read-out has been developed for the inner tracking system of CMS. The anode strips are 9 mu m wide with a pitch of 200 mu m. The sampling pitch of the back cathode is 400 mu m at a stereo angle of 50 mrad. Both coordinates are read-out from the same side of the detector substrate. Measurements of gain stability, fraction of induced charge on the back electrode, uniformity of response along the strip and rate capability have been performed in laboratory, using X-ray sources. Detection efficiency, spatial resolution, charge and space correlation have been measured with minimum ionizing particle beams at CERN
A study of experimentally induced coyotillo neuropathy and its modification in inbred rats
No full textVita.A peripheral neuropathy was induced in F/Crl BR inbred albino rats by the oral administration of coyotillo extract (Karwinskia humboldtiana). The progression of the disorder was modified by the separate administration of a pyridoxine deficient diet, pyridoxine supplementation, phenobarbital, and hydrocortisone. Neurological function was measured clinically by daily performance on a rotating rod (rotarod apparatus). Pathologic alteration was determined both by light and electron microscopic techniques. A dietary restriction of pyridoxine hastened onset of neurologic dysfunction, while supplementation with pyridoxine or administration of phenobarbital significantly delayed onset of neurological damage. The administration of hydrocortisone, while delaying the onset of failure (p<.05), did not increase the amount of extract required to induce failure. Coyotillo extract was administered to pyridoxine deficient rats at 2 dosage levels (40 mg/kg and 25 mg/kg); extract was given to the remaining groups at the lower dosage rate. Convulsions were observed within the experimental group of deficient rats at the higher dosage level, but no seizures were observed in subsequent experimental groups at the reduced coyotillo levels. Statistical data for the mean day of failure/mean dose for failure were as follows: High dosage study-abnormal (coyotillo) control, 20.1 days/17.3 mg; pyridoxine deficiency, 15.5 days/11.9 mg. Low dosage study-abnormal (coyotillo) control, 32.8 days/15.7 mg; pyridoxine deficiency, 26.3 days/11.3 mg; pyridoxine supplement, 44.4 days/22.2 mg; phenobarbital, 45.8 days/25.0 mg; hydrocortisone, 42.1 days/15.3 mg.
Intern experience at CH���M Hill, Inc.: an internship report
No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
Effect of diagnostic labeling and causal explanations on medical students' views about treatments for psychosis and the need to share information with service users.
No full textThis study examines whether medical students' views of treatments for 'schizophrenia' and of patients' rights to be informed about their condition and their medication were influenced by diagnostic labeling and causal explanations and whether they differed over medical training. Three hundred and eighty-one Italian students attending their first or fifth/sixth year of medical studies read a vignette portraying someone who met diagnostic criteria for 'schizophrenia' and completed a self-report questionnaire. The study found that labeling the case as 'schizophrenia' and naming heredity among its causes were associated with confidence in psychiatrists and psychiatric drugs. Naming psychological traumas among the causes was associated with confidence in psychologists and greater acknowledgment of users' right to be informed about drugs. Compared to first year students, those at their fifth/sixth-year of studies more strongly endorsed drugs, had less confidence in psychologists and family support, and were less keen to share information on drugs with patients. These findings highlight that students' beliefs vary during training and are significantly related to diagnostic labeling and belief in a biogenetic causal model. Psychiatric curricula for medical students should include greater integration of psychological and medical aspects in clinical management of 'schizophrenia'; more information on the psychosocial causes of mental health problems
