concentrations of major nutritional and trace elements (ca, p, mg, na, k, fe, zn, cu, mn, se,co, cr, ni, sr, ba) and toxic heavy metals (cd, pb) were analyzed in the meat of limousin, red angus andsalers bulls. elements were determined using inductively coupled plasma emission atomic spectrometry. theconducted research showed that the meat of compared breeds differed in the concentrations of cu...

The objective of this study was to evaluate the effects of replacing dry ground corn with crude glycerol on intake, apparent digestibility, performance, and carcass characteristics of finishing beef bulls. A completely randomized block design experiment with 25 d for adaptation and 100 d for data collection was conducted, in which 3,640 Nellore bulls (367 ± 36.8 kg; 18 ± 3 mo) were blocked by b...

During the past 23 yr, a large number of human illness outbreaks have been traced worldwide to consumption of undercooked ground beef and other beef products contaminated with Shiga toxin-producing Escherichia coli (STEC). Although several routes exist for human infection with STEC, beef remains a main source. Thus, beef cattle are considered reservoirs of O157 and nonO157 STEC. Because of the ...

Given the fundamental unidimensionality in the data on Supreme Court voting patterns 1951–1993 we observe, we are able to determine the identity of “median” members of each court in a fashion that does not require subjective coding of the extent to which particular cases reflect left-right issues. Also, while the exact numerical values of MDS-obtained locations cannot be compared across differe...

This paper describes a threshold concept-driven e-assessment system that supports teachers in writing effective formative multiple-choice questions, creating quizzes tailored to students’ learning pathways. The system, which has been co-designed with teachers, acts as the ‘bun’ on either side of an ‘eassessment burger’ pedagogically scaffolding quiz creation (the top of the bun), integrating th...
