Measuring ammonia concentrations in the barn using the Draeger(TM) and pHydrion(TM) tests
نویسنده
چکیده
Methods: Ammonia concentrations in farrowing, nursery, finisher, and gestating barns were monitored for 8 weeks using both the pHydrionTM test strips and the DraegerTM unit. The ammonia measurements were compared using bivariate correlation analysis. Average ammonia concentrations in each barn type were compared using an ANOVA. The precision and costeffectiveness of each assay were demonstrated by plotting the width of the confidence interval by the number of dollars available for ammonia detection, as well as by the number of tests performed.

A phase I/II clinical trial for adult recurrent glioma using 131i-tm-601, an iodinated peptide derived from scorpion venom
131I-TM-601 is a 36-amino acid peptide, called chlorotoxin (TM-601), derived from scorpion venom labeled with I-131. TM-601 binds a receptor on the surface of tumor cells, and not on normal cells. A single dose of 131I-TM-601 administered intracranially to human xenografted mouse models of glioma has been shown to extend survival up to 269% in multiple studies. 131I-TM-601 is in a multi-center ...

متن کاملAssessment of the Monthly Water Balance in an Arid Region Using TM Model and GIS (Case Study: Pishkouh Watershed, Iran)
Monthly discharge is one of the most important factors considered in designs and hydrological works. Some watersheds are not equipped with needed hydrometric equipment. In such a case average monthly discharge could be estimated from regional monthly water balance models of representative watersheds. In this study, Thornthwaite & Mather (TM) model were used in the Pishkouh watershed in arid cli...
