Birds Observed In The Potholes Region During 1953-1954, Paul A. Johnsgard Jan 1954

Birds Observed In The Potholes Region During 1953-1954, Paul A. Johnsgard

Papers in Ornithology

From June 15-August 15, 1953 and from February 15 to August 15, 19 5 4 the writer did extensive field work in the Potholes Region of Grant County,Washington, gathering data for an ecological study of the vegetation and wildlife of that area. During this time considerable observations of the bird life were made, which for the most part were restricted to the area adjacent to O'Sullivan Dam and Potholes Reservoir.


Fat Separation In Evaporated Milk. Iii. Gravity Separation And Heat Stability, R. B. Maxcy, H. H. Sommer Jan 1954

Fat Separation In Evaporated Milk. Iii. Gravity Separation And Heat Stability, R. B. Maxcy, H. H. Sommer

Department of Food Science and Technology: Faculty Publications

Fat separation is a continuous problem in the production, handling, and storage of evaporated milk. This defect becomes most objectionable during prolonged quiescent storage at high temperatures. The butterfat rises to the upper surface forming a viscous, leathery layer, which may prevent pouring of the milk from a relatively small opening.
To retard fat separation, the manufacturer attempts to obtain effective homogenization and sufficient coagulation of the proteins during sterilization to give the product a high viscosity or "heavy body" (1, 12, 14). These practical applications are aimed at three fundamental considerations: a reduction in the size of the fat …


Fat Separation In Evaporated Milk Ii. Age-Thinning Of Concentrated, Sterilized Milk, R. B. Maxcy, H. H. Sommer Jan 1954

Fat Separation In Evaporated Milk Ii. Age-Thinning Of Concentrated, Sterilized Milk, R. B. Maxcy, H. H. Sommer

Department of Food Science and Technology: Faculty Publications

During the process of sterilization of evaporated milk there is a gradual increase in the viscosity, or the body of the product. However, there is a reduction in the viscosity especially during the early phase of storage. This loss in viscosity, referred to as age-thinning, continues for a number of months.

Fat Separation In Evaporated Milk I. Homogenization, Separation, And Viscosity Tests, R. B. Maxcy, H. H. Sommer

Department of Food Science and Technology: Faculty Publications

The rising of fat in evaporated milk on prolonged storage will inevitably occur since the density of the fat particles is lower than that of the concentrated milk plasma in which they are suspended. It has been shown that the velocity of rise of individual fat globules in milk plasma is in good agreement with the velocity as predicated by Stokes' law (5). Troy and Sharp (7) also found the velocity of rise of globule clusters in general agreement with this law. Their observations on clusters were less precise, however, because of inherent complications arising from the irregularities in the …


Polyvinyl Alcohol-Fixative-Adhesive For Small Helminths And Protozoa, Glenn L. Hoffman Jan 1954

Polyvinyl Alcohol-Fixative-Adhesive For Small Helminths And Protozoa, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

Following the method of Brooke and Goldman (1949), the author was able to fix, mount and stain small helminths and parasitic protozoa of fish in polyvinyl alcohol-fixative smears. However, because there was much granular material in the PVA-Schaudin's mixture, AFA fixative was substituted for the Schaudin's. The PVA went into solution readily using this fixative. The solution was accomplished by adding 5 grams Elvanol #71-301 to 62 ml. of water, heating to 950 C. until dissolved and adding 5 ml. of acetic acid, 1-1/2 ml. of glycerine, 10 ml. of formaldehyde, and 30 ml. of 95 percent alcohol.


The Occurrence Of Ornithodiplostomum Ptychocheilus (Faust) (Trematoda: Strigeida) In Fish And Birds, Glenn L. Hoffman Jan 1954

The Occurrence Of Ornithodiplostomum Ptychocheilus (Faust) (Trematoda: Strigeida) In Fish And Birds, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

The metacercaria of Ornithodiplostomum ptychocheilush as been reported by Faust (1918; Illinois Biological Monographs 4(1): 1-120) from mesenteries of the squawfish, Ptychocheilus oregonensis (Richardson), and by Hughes and Piszcek (1928; Journal of Parasitology 15: 58-62) and Van Haitsma (1930; Transactions of the American Microscopical Society 49: 140-153) in the northeastern sand shiner, Notropis deliciosus stramineus (Cope). Van Haitsma (1930) found the adults in mergansers, Mergus americanus, M. serrator, Lophodytes cucullatus, and the old squaw duck, Harelda hyemalis. He also reared the metacercaria to the adult in young domestic ducks. Lyster (1940; Canadian Journal of Research 18D: 79-82) reported …

Spermatogenesis In The Sand Crab Emerita Analoga, Mario Martin Menesini Jan 1954

Spermatogenesis In The Sand Crab Emerita Analoga, Mario Martin Menesini

University of the Pacific Theses and Dissertations

Crustacean spermatozoa are among the most peculiarly modified germ cells in the animal kingdom. Many of their striking cytological specializations may be observed in the sperm cells or Emerita analoga, the so-called sand crab. This animal has been used by the writer for studies on spermatogenesis and on spermatozoan behavior during the summer or 1951, 1952, and 1953 at the Pacific Marine Station.


Plankton Studies Of The Tomales Bay, California, Andrew William Mcclain Jan 1954

Plankton Studies Of The Tomales Bay, California, Andrew William Mcclain

University of the Pacific Theses and Dissertations

These studies on the plankton of Tomales Bay were designed to determine the effects of such physical factors as tides, temperatures, salinities and sunshine on the quantities of various types of organisms, and to obtain a more comprehensive picture of estuarine life at the Pacific Marine Station. The studies were begun in the summer of 1948 and continued through the summer of 1953.

Although various studies have been conducted on different aspects of marine plankton, the only general treatments of the subject of which the writer is aware are those of Johnstone (1924), Ricketts and Calvin (1951), Sproaton (1949) and …


Biological Factors Involved In The Absenteeism Of Children From Stockton Public Schools, Fae-Belle Coudeyre Jan 1954

Biological Factors Involved In The Absenteeism Of Children From Stockton Public Schools, Fae-Belle Coudeyre

University of the Pacific Theses and Dissertations

Every state has a compulsory school attendance law, and yet at any time during the school year approximately 12 percent of the children will not be in school - cannot very well be in school, because of some physical, mental, or emotional handicap, either temporary or permanent.

These absentees are what are now often called the “exceptional” children, including the blind and partially-blind, the deaf and hard-of-hearing, the speech-defective, the crippled, the delicate, the epileptic, the mentally deficient, those with serious social maladjustments, together with those who are temporarily out of school because of a disease or accident. The total …
