What happens in the lung is that air meets blood. Figure 1 shows the lung's architecture. Focus your attention upon the smallest scale structures which are the termini of the air passages. These are the alveolar air sacs or, simply, alveoli. The inhalation/exhalation actions of the lung, alternately, flood these alveoli with atmospheric air and expel its oxygen-poor/carbon dioxide-rich replacement. Figure (2a) depicts, in a somewhat simplified manner, these alveoli with their appended venous blood suppliers, the pulmonary arteries. Figure {2b} shows the structure of the blood distribution system over a small, typical portion of the alveolar surface in much …

A Guide To What, How, Why And Why Not Of Psi, Vernon Williams, Robert Fuller, David Joseph

Personalized System of Instruction (PSI), or Keller Plan, Materials

The production and distribution of the film, Personalized System of Instruction: An Alternative, © 1973, by the Instructional Media Center of the University of Nebraska Lincoln was met with considerable interest among academics in the USA. A one time the film lending library had 24 copies of the film that were is almost continuous distribution in the early 1970s.

The film lead viewers to ask many questions and the Instructional Media Center got many requests for additional information. In response to that need, Vernon Williams of the Teaching and Learning Center and Professors Robert Fuller and David Joseph of …

Can Psi Help Him?

Personalized System of Instruction (PSI), or Keller Plan, Materials

PSI (Personalized System of Instruction) can help students learn!

If the lecture-taught course has you meeting the students as adversaries, continually answering redundant questions, haggling over half credit for half correct answers, and generally finding your students being inhibited by the lock-step timing of a lecture course, then PSI is an alternative.

It is also the title of a film, PSI: An Alternative, that imaginatively and graphically outlines an intriguing and dynamic system for learning.

PSI (also known as the Keller Plan) is self-paced, mastery oriented, student tutored for junior college and college level instruction with classes of all sizes …

Fundamental Energy Processes Of The Human Body, Thomas C. Campbell, Norman J. Chonacky

Physical Science Modules for Bioscience Students

Within the hand that holds this sheet of paper there throb thousands of engines; each with its own fuel requirements; each yielding varying amounts of work, heat, and waste output. Each is a cell in your body.

Of course, these cells are not completely independent. They share in a society, but especially in an economy, of the whole organism. This economy does not trade dollars of differing currencies; rather, its commerce is in energy of differing forms.

A particularly important asset is thermal energy. It is the natural by-product of the various energy conversion processes, the biochemical reactions within the …

Thermal Regulation Of The Human Body, Thomas C. Campbell, Norman J. Chonacky

Physical Science Modules for Bioscience Students

The supervision of the complicated task of managing your body's energy resources is laid to many ingenious systems, both chemical and physical, in your body. One group of such control systems keeps the temperature of the body relatively stable despite a wide range of variety and intensity of the energy conversion and utilization processes which occur there.

For example, increase in thermal stimulation of body temperature sensors may result in secretion of water by the sweat glands which in turn cools the skin surface and increases the heat outflow. In another scenario, thermal stimulation can initiate stricturing of certain blood …

The Effect Of Cyclic Differential Stress On Dilatancy In Westerly Granite Under Uniaxial And Triaxial Conditions, Mark D. Zoback, James D. Byerlee

United States Geological Survey: Staff Publications

Laboratory experiments have been performed on samples of Westerly granite in which the differential stress was repeatedly cycled to 85% of the intact sample strength. The experiments have shown that under uniaxial conditions the onset of dilatancy is reduced to fairly low stress; however, under triaxial conditions dilatancy can be an apparently stable process, and the onset of dilatancy is not affected by the repeated cycling. Thus the implication for midcrustal earthquakes is that the onset of dilatancy repeatedly occurs at relatively high stress levels. For example, our results indicate that at typical focal depths of 2.5 and 10 km …

Urban Geology Of Madison County, Indiana: Special Report 10, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

During recent years many of the population centers of Indiana have undergone growth that has resulted in expansion of urban uses into land that has been largely rural. As a result of that expansion, conflicts have arisen between expanding urban uses and the agricultural and mineral resource uses of land that lies near the centers of population. In addition, uncontrolled use of flood plains, steep slopes, and areas of soft sediments and high water tables has caused inconvenience and financial loss to individuals and industries that unknowingly have built structures in those places. Generally, these situations have developed as a …

We present a quantum mechanical treatment of laser-induced atomic fluorescence from molecular sodium. It is shown that such fluorescence data may be analyzed with an ν-centroid approximation and an accurate determination of the electronic transition moment may be made.

Oer For Mixed Neutrons And Γ Rays, Robert Katz, S. C. Sharma

Robert Katz Publications

A formula for the OER in a mixed field of neutrons and gamma rays (Hall, 1972a; 1972b) is given .... Our results, calculated from track structure theory (Katz and Sharma, 1973) and secondary particle-energy spectra in tissue from these neutrons (Caswell and Coyne, 1973; Dennis, 1972) are within 5 per cent of the values of O_mix found from the Hall formula, when that formula is supplied with calculated values of R_n, O_n, and O_γ, at appropriate survival levels. Our calculations suggest that the Hall formula may be used with confidence for neutrons of …

Repeatable Testing-A Tool For Learning Physics, David E. Golden, Robert Fuller, Donald D. Jensen

Robert G. Fuller Publications

Physics courses have traditionally used one-chance-only examinations as a probe to tell the professor how much physics each student has learned, with the result that physics examinations have been a common cause of anxiety among undergraduates.

Repeatable equivalent examinations, on the other hand, offer an alternative testing procedure which underscores material not mastered on the first examination and then allows remedial study of this material for the next examination. Furthermore, the thought that it will be possible to have another try at the examination greatly decreases the anxiety associated with examinations. While repeatable examinations are routinely used in Keller-plan courses, …

Second-Order Raman Scattering In Alkali Fluoride Crystals, S. L. Cunningham, T. P. Sharma, Sitaram Jaswal, M. Hass, John R. Hardy

John R. Hardy Papers

We present theoretical and experimental second-order Raman spectra for NaF, KF, RbF, and CsF. The theoretical calculation follows the formalism of Born and Bradburn. For the lattice-dynamic calculation we use the deformation-dipole model and present comparisons with measured dispersion curves. For the polarizability calculation, we retain all eight first-neighbor and all thirty second-neighbor polarizability coefficients. We find that, in addition to all of the first-neighbor coefficients, only three of the second-neighbor coefficients are needed to obtain good agreement between the calculated and observed spectra both as regards peak positions and over-all shape. Comparison with other types of calculations are made.

Deduction Of Asymptotic Steinmann Relations From The Regge Hypothesis, Paul Finkler, C. Edward Jones, M. Misheloff

Paul Finkler Papers

The analytic structure of the double-Regge vertex, which has previously been obtained from the Steinmann relation, is derived by using a natural generalization of the Regge hypothesis.
