Paleoethology seeks to study behavior of ancient animals by building inferential cases of hypothesized behavior patterns. Discusses paleoethological methods and reasons for studying therapsids. Also discusses metabolic rate and possible existence/use of vomeronasal organ to gain insight into the behavior/physiology of these ancient herbivors. (JN)

Discusses the nature of animal communication, including possible relationships between the physical structure of vocalizations and their functions in communicating. Provides tables of mammalian and avian sounds (by species/family) used in hostile and friendly appeasing contexts. (JN)

Lists and briefly describes computer programs recently added to those currently available from Project SERAPHIM. Program name, subject, hardware, author, supplier, and cost are provided in separate listings for Apple, PET, TRS-80 I or III, IBM, VIC-20, TERAK, and PDP-11 microcomputers. Includes corrections for two current Apple programs. (JN)

Describes an inexpensive device (around $8.00) for measuring light. The circuit used includes five resistors, three small capacitors, a cadmium sulfide light sensor, two integrated circuits, and two light-emitting diodes. The unit is constructed on a small perforated circuit board and powered by a 9-V transistor radio battery. (JN)

Guidelines to use when solving complex design problems and two illustrative examples were presented in Volume 16 (No. 1), page 12 of this journal. Two additional examples are presented, focusing on ASCEND-II, a flowsheeting system to help "design" a computer model for a process. (SK)

Reviews a one-semester senior plant design/laboratory course, focusing on course structure, student projects, laboratory assignments, and course evaluation. Includes discussion of laboratory exercises related to process waste water and sludge. (SK)

Encourages science educators to consider engaging students in science projects resulting in socially useful products. Educational presentations meant to perform social functions (soft products) and preparation/execution of environmental manipulations (hard products) such as pollution analysis, plant breeding, or administering medical tests are…

Universities and industry are forging new relationships to support academic research and industrial research and development, including the establishment of university/cooperative research centers. Discusses various cooperative projects at these research centers. Includes a list of representative R&D centers in biotechnology, building…

Outlines several ideas on introductory electrochemistry material suitable for college-level general chemistry. These include discussions of conductivity in solids and electrolytes, electrical quantities/properties, electrode potentials, and membrane potentials. Indicates that whatever strategy is used to present this material, the presentation…

Discusses engineering ramifications of electrochemistry, focusing on current/potential distribution, evaluation of trade-offs between influences of different phenomena, use of dimensionless numbers to assist in scale-over to new operating conditions, and economics. Also provides examples of electrochemical engineering education content related to…

Describes use of Warnier-Orr program design method for preparing general chemistry tutorial on ideal gas calculations. This program (BASIC-PLUS) is available from the author. Also describes a multipurpose computerized class record system at the University of Toledo. (JN)

Discusses use and applications of computer technology in chemistry, indicating that the importance of the computer has not been fully realized in the realm of organic synthesis. Includes discussions of various computer programs and systems currently used, supplemented by tables highlighting, for example, features of major computer-aided synthesis…

Discusses the chemistry and chemical engineering curriculum, programs, and activities at Delft University of Technology (Netherlands). Chemistry and chemical engineering are combined into a single department (subdivided into 10 workgroups) at the state-supported university. An outline of the four-year study program (which includes research/design…

Topics addressed in this review of chemistry in the troposphere (layer of atmosphere extending from earth's surface to altitude of 10-16km) include: solar radiation/winds; earth/atmosphere interface; kinetic studies of atmospheric reactions; tropospheric free-radical photochemistry; instruments for nitric oxide detection; sampling…

Discusses three avenues of problem-solving research: misconceiving natural laws, processing information, and constructing solutions. Suggests that the change in emphasis from problem to problem solver and the key role of "physics" problems are unifying aspects of the research. (JN)
