The effect of prerigor electrical stimulation pH decline, protein solubility and water holding capacity in beef muscles

Creator:: Elkhalifa, Elamin Abdalla
Abstract:: This study was designed to investigate the rate of pH decline, changes in protein solubility and in the water-holding capacity (WHC) of beef muscles subjected to pre-rigor electrical stimulation. Samples for the experiment were obtained from animals slaughtered at the Meat Science Laboratory, Oregon State University. Nine good quality steers...

The significance of glutathione conjugation for aflatoxin B₁ metabolism in rainbow trout and coho salmon

Creator:: Valsta, Liisa M.
Abstract:: In rodent models as well as in fish models there are significant species differences in the susceptibility toward aflatoxin B₁ (AFB₁) carcinogenesis. Mouse is less susceptible toward AFB₁ carcinogenesis than rat. Researchers have come to the conclusion that the lower susceptibility of mice is not a result of less effective...

The cholesterol content of muscle and adipose tissue from country natural beef

Creator:: Huang, Xiaolin
Abstract:: The cholesterol content (mg/100 g wet tissue) of the longissimus dorsi muscle and the subcutaneous adipose tissue of "Country Natural Beef" and regularly produced beef was determined by a spectrophotometric method. Proximate analysis (moisture, fat and protein contents) of both types of beef was also determined. Country Natural Beef (natural...

An econometric analysis of used tractor prices

Creator:: Bayaner, Ahmet
Abstract:: Farm equipment is becoming an increasingly important financial asset for many farmers. Tractors probably represent the single largest component of equipment asset value. As such, changes in tractor values can have a dramatic effect on a farmer's financial situation. Changes in equipment value can be attributed to depreciation and the...

Trophic and habitat requirements of two deposit-feeding stream invertebrates, Ptychoptera townesi (Diptera) and Paraleptophlebia spp. (Ephemeroptera)

Creator:: Mattingly, Rosanna
Abstract:: Ptychoptera townesi (false crane fly, Diptera) occur in high densities in an experimental stream section that has not been allowed to exceed bankfull flow for more than two decades, but are quite rare in areas both upstream and downstream from this section. By contrast, Paraleptophlebia spp. (mayfly, Epherneroptera) are relatively...

Hormonal and osmoregulatory aspects of smoltification in coho salmon, Oncorhynchus kisutch

Creator:: Specker, Jennifer Lee
Abstract:: Coho salmon smolts (Oncorhynchus kisutch) were transported at low and high densities. (12 and 120 g/L) for short and long periods (4 and 12 h). Because smolts can be transplanted directly to seawater, half of the fish in each treatment were transported to tanks containing seawater and half to tanks...

Incipient resuspension of silt-clay deposits in oscillatory and unidirectional flows

Creator:: Talebbeydokhti, Nasser
Abstract:: Incipient motion of cohesive sediment and the role of flow parameters were investigated for separate and combined unidirectional and oscillatory flows. Sediment from Sturgeon Lake, mainly silt and clay with organic matter, was used as bed material In recirculating and wave flumes. Bench-type experiments indicated that when the submerged sediment...
