Studies On The Respiratory System Of The Poky Strain Of Neurospora, Alfred Tissieres, Herschel Mitchell, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

It was shown recently that the poky strain of Neurospora accumulates large amounts of cytochrome c, but is deficient in cytochromes a and b and thus in cytochrome oxidase and succinic acid oxidase activities (1). These findings, which suggest that respiration in poky does not utilize the cytochrome system, led to a study of the respiratory system of poky compared with that of wild type. The experiments reported here are concerned with the effects of the inhibitors cyanide and azide on the respiration of intact mycelium of poky and wild type, the oxygen uptake of cell-free extracts in the …

Cytochromes And The Succinic Acid Oxidase System Of Poky Strains Of Neurospora, Francis A. Haskins, Alfred Tissieres, Herschell K. Mitchell, Mary B. Mitchell

Department of Agronomy and Horticulture: Faculty Publications

Recent investigations in this laboratory (1) have demonstrated that in Neurospora crassa growth characteristics representing at least two stable states are possible with the same constitution of nuclear genes. If a slow growing strain, designated poky, functions in a cross to wild type as the "maternal" or protoperithecial parent, then all progeny from the cross exhibit the poky character. If the cross is made in the reverse, or reciprocal manner, that is, with the wild type strain functioning as a protoperithecial parent, then all progeny are normal in growth rate.
During the course of the work on inheritance it was …

Concerning The Site Of Nitrogen Absorption In Rats Fed Autoclaved Or Raw Soybean Oil Mea, Raymond Borchers

Department of Biochemistry: Faculty Publications

Carroll, Hensley, and Graham (1) have concluded that much of the nitrogen absorption in rats fed raw soybean oil meal must take place in the cecum. This conclusion was reached from data showing that the apparent digestibility of raw soybean nitrogen in the terminal 20% of the small intestine was 32.65%, whereas in the feces the value was 76.96%. Values reported, for apparent digestibility of heated soybean nitrogen were 78.66% and 81.78%, respectively. This observation presented a notable advance in explaining the lower nutritive value of raw soybeans compared with autoclaved soybeans. It therefore seemed advisable to repeat this work …

Some Monogenetic Trematodes Of Marine Fishes From Fiji, H. W. Manter, Donald F. Prince

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This paper describes three new species of monogenetic trematodes collected by the senior author from fishes at Suva, Fiji, in 1951. A new genus is named for one of these species. A fourth species, previously known from India, is identified. Parasites of the numerous fishes of the South Pacific have been studied very little and, so far as we can learn, no Monogenea has been reported from this region. One difficulty met in collecting there was lack of adequate identification of the hosts. In these particular cases, only the common or native names of the fishes were obtained. Often, however, …

Studies On The Helminth Fauna Of Alaska. Xiv. Some Cestode Parasites Of The Aleutian Teal (Anus Crecca L.) With The Description Of Diorchis Longiovum N. Sp., Everett Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The Aleutian teal (Anas Crecca nimia Friedmann) has been relatively unavailable for helminth investigations by American workers because its range in North America is restricted to the western-most Aleutian Islands.

During some parasitological studies on Amchitka, Aleutian Islands, Alaska, in May and early June 1952, in connection with sea otter mortality, the writer had the opportunity to collect 20 adult Aleutian teal. These birds, consisting of 16 males (average weight, 392 grams) and 4 females (average weight, 353 grams) were taken at the beginning of the nesting season, Autopsies revealed that 16 (80%) of these ducks were parasitized by cestodes. …

On The Land Mammals Of St. Lawrence Island, Alaska, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The mammals occurring on St. Lawrence Island, Alaska, represent species which are widely distributed in boreal regions. They are not well known, however, and are poorly represented in collections. In the past, some of these mammals have been regarded as being specifically distinct from closely related forms occurring on the adjacent continents. It is the purpose of this paper to present some new data on these mammals, with particular reference to their taxonomy.

Two New Species Of Prosorhynchinae (Trematoda: Gasterostomata) From The Fiji Islands, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The following trematodes are part of a collection made by the author at Suva, Fiji in 1951.

1. Prosorhynchus squamatus Odhner, 1905 is believed to be distinct from P. crucibulus and most other species in the genus on the basis of its oval-shaped rhynchus. It thus remains, as originally, the type species of the genus.

2. Prosorhynchus thapari n. sp. is described from Plectropoma maculatum (Bloch) from Suva, Fiji. The "P. facilis (Ozaki, 1924)" of Nagaty (1937) is considered to be a synonym.

3. Neidhartia polydactyli n. sp. is described from Polydactylus plebius (Bonnaterre) from Suva, Fiji.

Streptomyces Leidnematis N. Sp., Growing On Two Species Of Nematodes Of The Cockroach, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

In 1948 Mr. J. R. Wennemark called the writer's attention to a filamentous growth extending from the cuticle of Leidynema appendiculata and Hammerschmidtiella diesingi, oxyurid nematodes found in the intestine of the American roach, Periplaneta americana, which was collected in Iowa City, Iowa. Because of the extreme filamentous accumulation it was thought to be the mycelium of a fungus. Further observation on material from roaches reared in Grand Forks, North Dakota, and Detroit, Michigan, showed that the organism was not fungus but a member of the Actinomycetaceae. Slides were sent to Profs. R. S. Breed and H. J. …

Scaphanocephalus Expansus (Crepl.), A Trematode Of The Osprey, In North America [Research Notes], Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

Examination of an osprey, Pandion haliaetus carolinensis furnished by Mr. Melvin Hoffman, Strawberry Point, Iowa, May, 1948, revealed about 30 trematodes which proved to be Scaphanocephalus expanses (Crepl.). This species which was redescribed in detail by Jagerskiold, (1904; Results of the Swedish Zoological Expedetion to Egypt and White Nile 1901 pt. 1) has a very large "expanded" flap-like anterior end and, to my knowledge, resembles no other trematode in that respect. The specimens have been deposited in the United States Nattional Museum Helminth Collection as No. 46437. Mr. Allen McIntosh (personal communication) has informed me that S. expanses has …

Farm And Ranch Economic Review For South Dakota, Agricultural Extension Service, South Dakota State College

SDSU Extension Circulars

The stage is set for another year of high-level economic activity. In this type of an economy, agricultural prospects are generally good. But, some weakening is possible late in the year. A stable or gently-rising level of wholesale prices is expected during most of 1953. Prices received by farmers may tend downward and prices paid, steady to upward. Net farm income may be a little lower than in 1952.

Strength Characteristics Of Multi-Ply And Single-Ply Handsheets, Yale Brandt

Paper Engineering Senior Theses

In a multi-ply handsheet there are three fundamental strengths. These fundamental strengths are the bonding between plies, bonding between fibers and the strength of the fibers. The strengths are interrlated and controlled by the preparation and mechanical handling of the stock.

The beating of the fibers, the consistency at which the sheet is formed, the couching pressure, and the final pressing all produce certain marked effects on the strength characteristics in a multi-ply handsheet.

In general it may be said that the strength characteristics of a given weight sheet may be increased by forming a multi-ply sheet.

The Influence Of Fiber Length And Fiber Length Distribution On Some Strength Characteristics Of A Commercial Pulp, David Kraske

Paper Engineering Senior Theses

In this thesis, four groups of fibers with varying average fiber lengths have been separated from a coniferous bleached kraft pulp which had been beaten to different levels of freeness. The fractionation of the pulp was accomplished with a Bauer-McNett fiber classifier. The groups of fibers were analyzed for average fiber length, fiber length distribution and for their strength characteristics.

The results of this survey show interesting and significant trends, particularly with regard to the apparent density, tensile strength and the tearing resistance of the various fractions. The contributions of the various fractions to the strength characteristics of the whole …
