Alternative Crops For Ethanol Fuel Production: Agronomic, Processing, And Economic Considerations, Thomas Dobbs, Duane Auch, Randy Hoffman, William R. Gibbons

Economics Research Reports (1969 - 2017)

This report is a result of the fuel alcohol research team's broadened focus during 1983. A comprehensive literature review was carried out to explore alternative starch and sugar crop alternatives for ethanol fuel production. Although the literature search was quite inclusive with respect to geographic regions, special emphasis was given to the agronomic and economic potential of various fuel alcohol crops in the Northern Plains region of the U.S., of which South Dakota is a part, and in LDCs of Asia, Africa, and Latin America. Our intent was to thereby determine possible energy crops deserving of more fuel alcohol research …

A Comparison Of Two Methods Of Presenting Nutrition Education To Senior Citizens Participating In A Congregate Meal Program, Janice M. Williams

Masters Theses

Senior citizens participating in a congregate meal program received nutrition education lessons in two different ways. One group received nutrition lectures, a second group recieved nutrition lectures accompanied by printed material. A third group served as a control. Each group contained an urban and rural site. The nutrition lectures and printed material centered on the Basic Four food groups. The lessons were presented to the subjects once a week in four successive weeks. The length of the nutrition lecture for each food group was twenty minutes. The senior citizen took pre and posttests to measure an increase or decrease in …

A Brief Overview Of The Life History, Physiology, And Ecology Of Minnesota Mosquitoes, Roger D. Moon

Journal of the Minnesota Academy of Science

The 51 species of mosquitoes known to occur in Minnesota share many biological attributes. They develop through seven life stages: an egg, four larval instars, a pupa, and an adult. Females lay eggs either on water or in substrates likely to be submerged later. Larvae and pupae occur in still , shallow water. Habitats vary among species and include tree holes, temporary snowmelt pools, rain pools, semi-permanent marshes, ponds, and riverside lagoons. Duration of the stages can be affected by diapause, temperature, and nutrition. Many species overwinter as dormant eggs, while some overwinter as larvae and others as diapausing females. …

Invertebrates Consumed By Dabbling Ducks (Anatinae) On The Breeding Grounds, George A. Swanson

Journal of the Minnesota Academy of Science

Foods consumed by dabbling ducks on the breeding grounds of south-central North Dakota were investigated during the spring and summer of 1967-80. Invertebrates dominated the diet of laying females. Animal foods comprised 99%, 72%, and 77% of the diet of laying blue-winged teal and northern shovelers, gadwalls, and mallards, and northern pintails, respectively. Factors that influence food selection include morphological adaptations for feeding, current physiological demands, the nutritional value of food items, and food availability. Preservation of waterfowl production habitat requires that the value of the wetland complex be recognized. Temporary, seasonal, and semi permanent wetlands provide abundant and highly …

Potential Effects Of Insecticides On The Survival Of Dabbling Duck Broods, Patrick W. Brown, Malcolm L. Hunter Jr.

Journal of the Minnesota Academy of Science

The effect of insecticides on the survival of dabbling duck broods was investigated by reviewing studies of natural brood survival and depression of growth rates for ducklings raised on wetlands treated with insecticides. Ducklings raised on an insecticide-treated wetland took 5 days longer to reach the normal 14-day body weight. Normal brood mortality for three species of dabbling ducks was highest in the first two weeks of life and ranged from 25% to 51%. High mortality of young ducklings is probably related to their small size. Thus, mortality rates could be in creased to 35% to 70% because of the …

The Effects Of Microwave Energy And Convection Heating On Wheat Starch Granule Transformations, N. K. Goebel, J. Grider, E. A. Davis, J. Gordon

Food Structure

Wheat starch-water dispersions at 1:1, 1:2, 1:4, and 5 95 (w/w) starch:water ratios, representing systems with varying levels of water availability , were heated under static conditions to 75°C by microwave energy at two power settings and by convection heating. Starch granule swe lling was evaluated by light and scanning electron microscopy. Six stages in swelling were identified on the basis of s welling of small and large granules and development of an extragranular matrix. The range of swelling stages found in different locations within a sample decreased as water became more available and less limiting. At each starch:water ratio, …

Preliminary Evaluation Of Lectins As Fluorescent Probes Of Seed Structure And Composition, S. Shea Miller, S. H. Yiu, R. G. Fulcher, I. Altosaar

Food Structure

Several commercially available fluoresceinisothiocyanate and rhodamine isothiocyanateconjugated plant lectins have been applied to cereal and oilseed tissues to permit identification and localization of specific structures and carbohydrates by fluorescence microscopy . Ulex europeaus Agglutinin I (UEAl) and Ricinis communis Agglutinin I (RCA I) showed specificity for the amyloids in rapeseed cotyledonary cell walls . Wheat Germ Agglutinin (WGA) bound to rapeseed coat mucilage, as well as fungal hyphae in infected wheat . Lens culinaris Agglutinin (LCA) bound only to starch in cereal sections, and at higher magnifications of isolated starch granules , the annular structure was clearly visible.

G84-716 Management Of The Weanling Calf, Paul Q. Guyer, Donald B. Hudson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide outlines a program for preventing sickness and death losses in newly weaned calves, including stress prevention, vaccinations, nutrition, and treatment of sick calves.

Sickness and death loss following weaning robs both calf producers and cattle feeders of potential profits. The weanling calf has not acquired adequate immunity to the variety of diseases that plague the beef industry. At weaning and/or shipping, the calf is usually subjected to various stresses, in addition to being separated from its mother, that contribute to disease outbreaks. A program for minimizing weight loss, sickness, and death in newly weaned calves should include: 1) …

The Effects Of Regulation On Aquaculture Development, Derek S. Busby

Marine Affairs Theses and Major Papers

A comparative study of the regulatory frameworks surrounding aquaculture in the states of Florida, Mississippi, and Rhode Island is conducted beginning with a generalized study of basic legal premises of aquaculture-related law common to each state. This is followed by a detailed study of the statutory authority for aquaculture regulation and the agencies which control aquaculture activities in each state. In conjunction with the law analysis an Index of Specialization (ISP) study is conducted for each state to determine a relative ranking of diversity of crop production relative to each state’s overall aquaculture production.

Marine Resources: The Presentation Of A Business Plan, K. Scott Colby

Marine Affairs Theses and Major Papers

The once questionable technology of hatchery production has become routine and, with the recent development of up-welling techniques, is more effective and efficient. The supply of natural shellfish and fishery stocks is on the decline and this trend is expected to continue. Aquaculture has been the solution to this problem in many European countries and the United States is currently attempting to remove domestic obstacles through its National Aquaculture Plan. The proprietor has experience in the production of various marine invertebrates and has designed, built and operated a producing shellfish hatchery. By using a unique up-welling juvenile culture system a …

Toward A Concise Definition And Perspective For Biology, Arthur V. Brown, Kristine Basinger Brown

Journal of the Arkansas Academy of Science

The content of introductory biology courses at the high school and college levels are currently being re-examined. Many biological educators favor revision of the high school biology courses to a format that directly addresses current social issues to "promote good citizenship". We believe it would be more meaningful to teach the fundamental principles of biology, the study of living systems. Properly defining biology, by defining a living system, should help identify important topics to include in a basic biology course. Emphasis should be placed on subjects which would contribute most to the development of a basic understanding of how all …

Aquatic Feeding By Moose: Selection Of Plant Species And Feeding Areas In Relation To Plant Chemical Composition And Characteristics Of Lakes, D. Fraser, E R. Chavez, J. E. Paleheimo

Feeding Behavior Collection

Aquatic feeding by moose was studied with emphasis on (i) the chemical composition of aquatic plants compared with terrestrial browse, (ii) the chemical composition of preferred and unpreferred aquatic plant species and (iii) characteristics of preferred feeding areas. Compared with woody browse, aquatic plants had much higher levels of sodium and iron, and similar levels of other nutrients tested. In a "cafeteria" selection experiment, moose consistently ate seven species of aquatic plants (preferred plants), consistently rejected five species (unpreferred plants), and gave an intermediate response to seven species. Preferred species had significantly higher sodium content. Those in the intermediate class …

Synandromyces Telephani (Ascomycetes: Laboulbeniales) From Illinois And Development Of Its Trichogyne, Richard K. Benjamin

Aliso: A Journal of Systematic and Floristic Botany

Synandromyces telephani, originally described from Argentina and subsequently recorded (immature specimens only) from Guatemala, Jamaica, and Trinidad, is reported from Illinois, U.S.A. Characteristics of the genus Synandromyces are reviewed and compared with those of two nearly related genera, Acompsomyces and Stemmatomyces. A key to the nine known species of Synandromyces is presented. Development of the relatively gigantic, determinate, two-celled trichogyne of S. telephani is described and illustrated from the Illinois collections. Trichogyne morphology and other thallus characteristics are discussed in relation to their possible significance in assessing relationships among Acompsomyces, Stemmatomyces, Synandromyces, and other genera of Laboulbeniales.

Fisheries Report No 63 - Assessment Of Artificial Feeds For Battery Culture Of A Freshwater Crayfish, Marron (Cherax Tenuimanus) (Decapoda: Parastacidae), Dr N. Morrissy

Fisheries Research Reports

Performance of juvenile crayfish, 0.1-5 g, on a variety of commercial crustacean feeds was tested under conditions of individual housing ("battery culture"), where sources of additional feed were minimized (detritus), or eliminated (cannibalism) Survival was close, or equal, to 100% over 50 day test periods, a reflection of optimal battery conditions rather than feeding, since survival over 100 days for an unfed (control} group was also 100%. No ecdysiad mortality, or trauma, occurred with crayfish, up to 10g, in compartments of area 75 cm. Growth performance in tests was rated by separate ratios for ecdysial increment and frequency, relative to …

G84-718 Cannibalism: Cause And Prevention In Poultry, Earl W. Gleaves

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses reasons why cannibalism occurs in poultry, and provides management procedures for preventing it, including three methods of beak trimming.

Chickens, turkeys, pheasants and quail will literally pick each other to death at times. This problem can be very expensive for the producer and can make life for the flock very uncomfortable. Once cannibalism starts, it readily becomes a habit that must be stopped.

For our purposes, cannibalism includes feather pulling, toe pecking and head, wing, and tail picking. Prevention is much easier for man and bird than is treatment.

Effect Of A Prescribed Fire On Herbage Production In Southwestern Ponderosa Pine On Sedimentary Soils, Brian P. Oswald, W. Wallace Covington

Faculty Publications

An area burned by prescription in 1977 and a nearby unburned area were measured in 1974 and 1980 to determine effects of the burn on herbage and forage production. Herbage production on the burned area increased significantly in 1980 over its 1974 level, in addition to being greater than the 1980 control production. However, the proportion of forage production to total herbage production in 1980 on the burned area decreased after the burn, and was significantly less than the control area forage production. This reduction in forage production can be attributed to the increase of nonforage species, notably bracken fern. …

An Analysis Of Microstructural Factors Which Influence The Use Of Muscle As A Food, R. G. Cassens, C. E. Carpenter, T. J. Eddinger

Study of structure of muscle provides information on the location and arrangement of various components and the changes which may be inflicted upon them. The structura l features of muscle have been descr ibed in detail down to the molecular level, but rega rding its use as a food, special interest centers on the connective tissue component and on myofibri llar proteins . Muscle comprises about 1/3 of the live weight of the a ni mal and is not static , but rather is subject to major changes in properties associated with growth, repair and se nescence. It is apparent …

Ultrastructure Of Quinoa Fruit (Chenopodium Quinoa Willd), E. Varriano-Marston, Alicia Defrancisco

Food Structure

The structure of quinoa (Chenopodium quinoa) fruit before and after germination was studied using electron microscopy. Protective coverings include a perianth consisting of loosely adhering cell s which are readily removed by washing, a pericarp and two seed coat layers. Starch granules fill the perispenn cells and are arranged in 18 to 20 oblong aggregates. Limited hydrolysis of the starch occurs after 24 hrs of germination, with amylolytic erosion of large granules occurring at the hilum and periphery of the granul es. Ungerminated embryo cells contain protein bodies with phosphorus-containing globoid inclusions. Essentially complete hydrolysis of the embryo protein bodies …
