Reactivity of Nellore steers in two feedlot housing systems and its relationshi...

To evaluate reactivity to assess the temperament of Nellore steers in two feedlot housing systems (group pen or individual pen) and its relationship with plasmatic cortisol, 36 experimental units were observed five times at 28-day intervals of weight management during a 112-day feedlot confinement. A reactivity score scale ranging from 1 to 5 was applied when an animal was in the chute system. To the calmest an...

Use of tetramethylbenzidine for the spectrophotometric sequential injection det...

A sequential injection (SI) method was developed for the spectrophotometric determination of chlorine based on the reaction between tetramethylbenzidine (TMB) and free chlorine. The advantages resulting from the use of TMB are considerable: TMB is highly selective for chlorine, it enables a fairly low quantification limit and represents a less toxic alternative to reagents such as tolidine. The use of this reac...

ISEKI-Food - Integrating Safety and Environmental Knowledge Into Food Studies t...

The main objectives of the ISEKI-Food project (104934-CP-1-2002-1-PT-ERASMUS-TN) are to contribute for the harmonisation of the studies in Food Science and Engineering in Europe, and to develop and adapt curricula to include safety and environmental topics. The main activities underway and conclusions will be presented and can be obtained at the web site http://www.esb.ucp.pt/iseki/.
