Cardiac output by model flow method from intra-arterial and finger tip pulse pressure profiles
No full textModelflow®, when applied to non-invasive fingertip pulse pressure recordings, is a poor predictor of cardiac output (Q’ litre· min-1). The use of constants established from the aortic elastic characteristics, which differ from those of finger arteries, may introduce signal distortions, leading to errors in computing Q’. We therefore hypothesized that peripheral recording of pulse pressure profiles undermines the measurement of Q’ withModelflow®, so we compared Modelflow® beat-by-beat Q’ values obtained simultaneously non-invasively from the finger and invasively from the radial artery at rest and during exercise. Seven subjects (age, 24.0 + - 2.9 years; weight, 81.2 + - 12.6 kg) rested, then exercised at 50 and 100 W, carrying a catheter with a pressure head in the left radial artery and the photoplethysmographic cuff of a finger pressure device on the third and fourth fingers of the contralateral hand. Pulse pressure from both devices was recorded simultaneously and stored on a PC for subsequent Q’ computation. The mean values of systolic, diastolic and mean arterial pressure at rest and exercise steady state were significantly (P < 0.05) lower from the finger than the intra-arterial catheter. The corresponding mean steady-state Q’ obtained from the finger (Q’porta) was significantly (P < 0.05) higher than that computed from the intra-arterial recordings (Q’pia). The line relating beat-by-beat Q’porta and Q’pia was y = 1.55x - 3.02 (r2 = 0.640). The bias was 1.44 litre · min-1 and the precision was 2.84 litre · min-1.The slope of this line was significantly higher than 1, implying a systematic overestimate of Q’ by Q’porta with respect to Q’pia. Consistent with the tested hypothesis, these results demonstrate that pulse pressure profiles from the finger provide inaccurate absolute Q’ values with respect to the radial artery, and therefore cannot be used without correction with a calibration factor calculated previously by measuring Q’ with an independent method

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The effects of β1-adrenergic blockade on cardiovascular oxygen flow in normoxic and hypoxic humans at exercise
No full textPatients:6 healthy subjects mean age 25.5 years were studied.TypeofStudy:This study determined the effects of selective beta-adrenergic blockade with Lopresor on the oxygen flow in arterial blood (Q̇aO2) and oxygen flow in mixed venous blood (oxygen return, Q̇v̄O2) in humans exercising in normoxia and in acute normobaric hypoxia.DosageDuration:Initially 7.5 mg iv bolus; additional doses up to 30-40 mg until a quasi-complete receptor blockade was achieved.Results:Without Lopresor, PaO2 and PaCO2 were lower in hypoxia than in normoxia. In both hypoxia and normoxia conditions, Lopresor did not induce significant differences in PaO2 and PaCO2 with respect to control condition. Arterialized blood pH was higher in hypoxia than in normoxia and was unaffected by Lopresor. [La]b was higher in hypoxia than in normoxia and was unaffected by Lopresor. The highest [La]b values were observed at 150 W in hypoxia. Without Lopresor the fH, SV, Q̇ and Q̇aO2 increased significantly at exercise in both normoxia and in hypoxia. fH was systematically and significantly higher in hypoxia than in normoxia at each workload. SaO2 and CaO2 were lower in hypoxia than in normoxia. In hypoxia, they also decreased with increasing workload. As a result of this, and despite the lower arterial-venous O2 differences in hypoxia, the O2 extraction coefficient was greater in hypoxia than in normoxia. In normoxia the difference between Q̇aO2 and V̇02 (=Q̇V̄O2) did not change with increasing workload. In hypoxia, Q̇V̄O2 decreased as a function of workload. The resting Q̇v̄O2 value in normoxia was significantly lower than the corresponding invariant values at exercise. In hypoxia the resting Q̇V̄O2 value did not differ significantly from the corresponding value in normoxia. However, the Q̇V̄O2 values at 100 and 150 power (W) in C were significantly lower than the corresponding values in normoxia. With Lopresor, the fH, SV, Q̇, and Q̇aO2 increased significantly during exercised in both normoxia and hypoxia conditions. At rest and at each workload, Lopresor systematically and significantly decreased fH, both in normoxia and in hypoxia. The lower fH at any given V̇O2 implied a significant increase in the oxygen pulse with Lopresor. Q̇ values were found significantly higher at each fH level under Lopresor in hypoxia than in normoxia as a consequence of increased SV. SV values were significantly higher under Lopresor than in control condition in both normoxia and hypoxia. In normoxia, Q̇ was significantly decreased by Lopresor at 100 power (W) exercise and above, and in hypoxia at rest and at 50 W. As in control condition, SaO2 and CaO2 were lower in hypoxia than in normoxia. In hypoxia they also decreased with increasing workload. In both conditions the values observed under Lopresor were not significantly different from those found in control condition. The Q̇v̄O2 decrease as a function of workload in hypoxia paralleled an analogous decrease in SaO2.AdverseEffects:No adverse events were mentionedAuthorsConclusions:The results of the present study are in agreement with the tested hypothesis, as this study showed that selective blockade of beta1-adrenergic receptors decreased Q̇aO2 and Q̇v̄O2 significantly during exercise in normoxia as well as during rest and light exercise in hypoxia.FreeText:Experiments were performed in normoxia and in acute normobaric hypoxia. In both conditions the subjects performed two incremental exercise tests, one without Lopresor and one after having induced quasi-complete beta-adrenergic blockade with Lopresor. Tests: oxygen consumption (V̇O2), carbon dioxide output (V̇CO2), expired ventilation (V̇E), heart rate (fH, electrocardiography), SaO2 (oximetry), hemoglobin (Hb), blood lactate concentration ([La]b), cardiac output (Q̇), stroke volume (SV), arterialized blood carbon dioxide partial pressure (PaCO2), and arterialized blood oxygen partial pressure (PaO2)
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
Cardiac output by Modelflow® method from intra-arterial and fingertip pulse pressure profiles
No full textModelflow®, when applied to non-invasive fingertip pulse pressure recordings, is a poor predictor of cardiac output (Q˙ , litre · min−1). The use of constants established from the aortic elastic characteristics, which differ from those of finger arteries, may introduce signal distortions, leading to errors in computing Q˙ .We therefore hypothesized that peripheral recording of pulse pressure
profiles undermines the measurement of Q˙ with Modelflow®, so we compared Modelflow® beat-by-beat ˙Q values obtained simultaneously non-invasively from the finger and invasively from the radial artery at rest and during exercise. Seven subjects (age, 24.0+−2.9 years; weight, 81.2+−12.6 kg) rested, then exercised at 50 and 100 W, carrying a catheter with a pressure head in the left radial artery and the photoplethysmographic cuff of a finger pressure device on the third and fourth fingers of the contralateral hand. Pulse pressure from both devices was recorded simultaneously and stored on a PC for subsequent ˙Q computation. The mean values of systolic, diastolic and mean arterial pressure at rest and exercise steady state were significantly (P<0.05) lower from the finger than the intra-arterial catheter. The corresponding mean steady-state ˙Q obtained from the finger (˙Qporta) was significantly (P<0.05) higher than that computed from the intra-arterial recordings (˙Qpia). The line relating beat-by-beat ˙Qporta and ˙Qpia was y=1.55x−3.02 (r2 =0.640). The bias was 1.44 litre · min−1 and the precision was 2.84 litre · min−1. The slope
of this line was significantly higher than 1, implying a systematic overestimate of ˙Q by ˙Qporta with respect to ˙Qpia. Consistent with the tested hypothesis, these results demonstrate that pulse
pressure profiles from the finger provide inaccurate absolute ˙Q values with respect to the radial artery, and therefore cannot be used without correction with a calibration factor calculated previously by measuring ˙Q with an independent method

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
