In both experiments quail were raised on a soybean-meal glucose-monohydrate ration. At 25% egg production the quail received diets containing 0, 10 or 25 ppm of dieldrin in...

The influence of calcium carbonate and clacium gluconate on tetracycline absorption in man

Creator:: Owings, Gary Lee
Abstract:: This experiment was designed to investigate the in vivo effects of calcium ions on tetracycline absorption when oral doses of tetracycline and calcium-containing medications were administered concurrently. Twenty-one human volunteers were selected and divided into three equal-sized groups: Group A, Group B, and Group C. Each volunteer in Group A...

Screen printing on tensioned warps in handwoven fabrics

Creator:: Mezera, Margaret Ann
Abstract:: The creating of pattern in woven fabrics by placing design on the warps and/or wefts before they are woven is ancient. Primary examples of these textiles are ikat, which is a resist dyeing technique, and chine, in which design is painted or in some way printed on the tensioned warp...

Effects of DDE and DDT on the performance of coturnix quail

Creator:: Robson, William Andrew
Abstract:: Two experiments were conducted to investigate the effects of p, p'-DDE and p, 'Dr-DDT on the performance of Coturnix quail (Co-. turnix coturnix japonica) fed an adequate and deficient calcium diet. In Experiment I four hundred day-old Coturnix quail of mixed sex were fed 0 and 50 ppm of p,...

A compiler-compiler for the CDC 3300

Creator:: Rucker, Jimmy Ivan
Abstract:: This thesis describes a syntax-directed compiler-compiler called COMCOM which has been implemented by the author on the CDC 3300 under the OS-3 operating system. The theory and terminology of the parsing method and compiler-compilers in general are briefly discussed. COMCOM uses Floyd's operator precedence bottom-up parsing technique which avoids backup...

Variation in metabolism, thallus characteristics, and water relations of three populations of Loboria pulmonaria from western Oregon

Creator:: Neil, Garry Allen
Abstract:: A physio-ecological study of Lobaria pulmonaria (L. ) Hoffm. was done to determine if geographic variation occurred within the species. Lobaria pulmonaria was collected from Table Mountain, Oak Creek, and Lost Prairie, located in the Coast Range, Willamette Valley, and Cascade Range respectively in Western Oregon. During 1971 and 1972...

Design of a waterjet system for excavation of commercial crab pots buried in ocean sediment

Creator:: Le Febvre, Patrick Elmer
Abstract:: The design of a more efficient waterjet system for excavation of commercial crab pots buried in ocean sediment was undertaken. The work resulted in the design of an improved nozzle with performance that was shown to be significantly better than that of previously used nozzles. Greater sand penetration and excavation...

Pathogenesis of bovine adenoviral infections in newborn calves

Creator:: Peterson, Patricia L.
Abstract:: Three newborn, colostrum deprived calves were inoculated by the intranasal, intratracheal, conjunctival and oral routes with a subgroup II bovine adenovirus strain 7T. An initial viremia and febrile response occurred in all calves with widespread dissemination of the virus through the body. Clinical signs consisted of pyrexia, soft feces and...

Analysis of heat transfer, including axial conduction, for laminar tube flow with arbitrary circumferential wall heat flux

Creator:: Faghri, Mohammad
Abstract:: This thesis is concerned with the analysis of heat transfer in a tube with forced flow under conditions of an arbitrary variation of wall heat flux both axially and circumferentially. This total study is separated into two distinct problems which are presented separately. The first is the case of a...

Pile hammer selection by driving stress analysis

Creator:: Barrero-Quiroga, Franklin
Abstract:: This paper presents an application of the wave equation to the problem of selecting a driving hammer for prestressed concrete piles. The potentially damaging effects of these types of hammers on various prestressed concrete piles were analyzed by means of parametric studies carried out on a hypothetical group of problems...
