Principles Of Feeding Small Flocks Of Chickens At Home, David D. Frame Aug 2008

Principles Of Feeding Small Flocks Of Chickens At Home, David D. Frame

All Current Publications

Owning a small flock of chickens is increasing in popularity, particularly in areas prohibiting the raising of larger domestic animals. Chickens not only furnish a ready source of home-grown meat and eggs, but also provide great pleasure as exhibition stock and even as pets.

Squash Bug, Diane Alston, James Barnhill Aug 2008

Squash Bug, Diane Alston, James Barnhill

All Current Publications

Squash bug (Anasa tristis) is a “true bug” with piercingsucking mouthparts (Order Hemiptera) in the leaffooted bug family (Coreidae). It is common throughout the U.S. and found from Canada to Central America. Adults (Fig. 1) emit a foul odor when disturbed and may be called “stink bugs”; however, true stink bugs are in a different true bug family.

Effect Of High Intensity Ultrasound On Crystallization Behavior Of Anhydrous Milk Fat, Silvana Martini, A. H. Suzuki, R. W. Hartel Jul 2008

Effect Of High Intensity Ultrasound On Crystallization Behavior Of Anhydrous Milk Fat, Silvana Martini, A. H. Suzuki, R. W. Hartel

Nutrition, Dietetics, and Food Sciences Faculty Publications

The need to eliminate trans-fatty acids from foods’ formulation resulted in the exploration of new lipid sources and alternative processing conditions that will improve the physicochemical characteristics and nutritional qualities of lipid-based foods. In general, the physicochemical characteristics of lipid networks depend on the microstructure and crystallization behavior of the system. The objective of this work was to use high intensity ultrasound (HIU) as an additional processing condition to alter the crystallization behavior of a lipid model system (anhydrous milk fat). Results show that HIU application not only decreases the induction time of crystallization (faster crystallization) at a constant crystallization …

Nutrition, Dietetics, and Food Sciences Faculty Publications

The purpose of this qualitative study, conducted in two Navajo Nation chapters, was to learn what makes Navajo marriages strong because no research has been done on this topic. Twenty-one Navajo couples (42 individuals) who felt they had strong marriages volunteered to participate in the study. Couples identifi ed the following marital strengths: (1) maintain communication, (2) nurture your relationship, (3) learn about marriage, (4) be prepared for marriage, and (5) have a strong foundation.

Water Resource Requirements Of Corn-Based Ethanol, Stanley Mubako, Christopher L. Lant Jul 2008

Water Resource Requirements Of Corn-Based Ethanol, Stanley Mubako, Christopher L. Lant

Environment and Society Faculty Publications

Ethanol derived from fermentation of corn is a very water-intensive product with water to ethanol mass ratios of 927 to 1178 and volumetric ratios of 1174 to 1492 for the major rainfed corn-growing U.S. states of Illinois and Iowa and the leading irrigated corn-growing state of Nebraska, respectively. Over 99% of water requirements are for growing corn feed stocks, with 99% of that amount in Illinois and Iowa, occurring as evapotranspiration of rainfall in corn fields, and 60% as evapotranspiration of applied irrigation water in Nebraska. As a rough measure of water quality impacts, 65.5 g N, 23.8 g P, …

Control Of Listeria Monocytogenes In Ready-To-Eat Meats Containing Sodium Levulinate, Sodium Lactate, Or A Combination Of Sodium Lactate And Sodium Diacetate, R. L. Thompson, C. E. Carpenter, Silvana Martini, Jeff Broadbent Jun 2008

Control Of Listeria Monocytogenes In Ready-To-Eat Meats Containing Sodium Levulinate, Sodium Lactate, Or A Combination Of Sodium Lactate And Sodium Diacetate, R. L. Thompson, C. E. Carpenter, Silvana Martini, Jeff Broadbent

Nutrition, Dietetics, and Food Sciences Faculty Publications

This study investigated the use of sodium levulinate to prevent outgrowth of Listeria monocytogenes in refrigerated ready-to-eat (RTE) meat products. Turkey breast roll and bologna were formulated to contain 1%, 2%, or 3% (w/w) sodium levulinate, 2% sodium lactate, a 2% combination of sodium lactate and sodium diacetate (1.875% sodium lactate and 0.125% sodium diacetate), or no antimicrobial (control). Samples of the RTE products were sliced, inoculated with 102 to 103 CFU/cm2 of a 5-strain cocktail of L. monocytogenes, vacuum packaged, and stored at refrigeration temperature for 0 to 12 wk. Counts reached 108 CFU/cm2 on control turkey roll product …

Centipedes, Erin W. Hodgson, Paul Bingham, Alan H. Roe Jun 2008

Centipedes, Erin W. Hodgson, Paul Bingham, Alan H. Roe

All Current Publications

Centipedes are long, slender arthropods in the class Chilopoda. Centipede means “hundred feet” because they appear to have many legs. Insects, millipedes and arachnids are close relatives. Centipedes should be considered beneficial because they are exclusively predatory. They eat a wide variety of smaller invertebrates, including insects. However, centipedes may be considered a nuisance to homeowners when they are found inside.

In Utah, there are typically three generations of corn earworm (CEW) each year. The first generation of adults either come from overwintering pupae (southern and central Utah), or migrate into northern Utah. The adult moth is tannish brown with a 1 1/2 inch wingspan. The front wings are marked with a distinct dark spot in the center and darker bands near the outer margins. The hind wings are lighter tan, with a dark band along the outer margins. The male moths have green eyes. Moth flight occurs primarily on warm, overcast evenings. Moth populations can be monitored using pheromone or …
