Inconel 718 is considered difficult to machine because of its ability maintain properties at high temperatures. The low thermal conductivity the alloy causes accelerated tool deterioration when machining. Selective laser melting (SLM) additive manufacturing introduces a possibility eliminating these difficulties, and producing complex shapes with this difficult-to-machine material. However, sur...
AIMS To estimate prevalence and antimicrobial susceptibility of enterococci in faeces collected in 2007 from U.S. dairy cattle. METHODS AND RESULTS A total of 718 faecal samples from 122 dairy cattle operations from 17 US States were collected and cultured for the presence of enterococci.

Objective—To assess associations of occupational categories and job characteristics with prevalent hypertension. Methods—We analyzed 2,517 Multi-Ethnic Study of Atherosclerosis (MESA) participants, working 20+ hours per week, in 2002–4. Results—Higher job decision latitude was associated with a lower prevalence of hypertension, prevalence ratio (PR)=0.78 (95% CI 0.66–0.91) for the top vs. botto...
