Anthropogenic sources account for much of the zinc (Zn) in the environment. Constraining the isotopic composition of anthropogenic Zn is therefore essential to understanding the environmental biogeochemical cycling of Zn isotopes. This study examines the isotopic variability in several different categories of anthropogenic Zn. Pure Znmetal and Zn dust are the rawmaterials used in many Zn-contai...

Abstract Cold Metal Transfer (CMT) lap joint of Al6061-T6 and Galvanized steel is studied in this paper using design experiments method. Welding parameters considered for the work includes stick out distance (10 mm −14 mm), wire-feed speed (3.5 m min −1 – 4 ) torch angle (10˚ to 15˚). Weld strength optimized by Taguchi analysis optimizing input variables with 100% argon gas 14 overlap region 13...

Continued increases in Johne’s disease around the world suggest more information is needed to understand the mechanisms by which the causative agent, Mycobacterium avium subsp paratuberculosis (MAP), is spread among livestock on the farm site. Livestock watering troughs are frequented by all animals on a farm; they provide a moist, nutrient-rich environment for bacterial survival, and the troug...
