The impeller under consideration is a rotor wheel of a centrifugal compressor, made of 17-4PH martensitic precipitated hardening stainless steel.Its total operating lifetime was estimated to 80,000 h, but it Target Holders fractured beforehand, 4 days after the scheduled overhaul without any observed pre-symptoms.The important causes of the failure
Sediment as a constituent of Mediterranean benthic communities dominated by Caulerpa racemosa var. cylindracea
Mediterranean macroalgal assemblages in Inlet Hose Nut areas invaded and non-invaded by Caulerpa racemosa var.cylindracea were compared and trapped sediments were characterised.Results showed that assemblages invaded by C.racemosa var.cylindracea differed greatly from non-invaded ones: encrusting and erect algae, both articulated and foliose, decre
Comparison of transport crates contamination with Campylobacter spp. before and after the cleaning and disinfection procedure in broiler slaughterhouses
ABSTRACT: Campylobacteriosis is one of the most common types of bacterial gastroenteritis affecting humans, and poultry is considered a major source of the causative organism, Campylobacter spp.Broilers may arrive contaminated at slaughterhouses, and transport crates could be considered a potential source of contamination.Thus, cleaning and disinfe
