Eleven sweet pepper cultivars were evaluated for their susceptibility to F. lactis, and although
all were Susceptible, the degree of susceptibility varied. Fusarium lactis was subsequently isolated and identified from infected sweet pepper fruits from greenhouses in Saskatchewan and Ontario in 2006 and 2007.”
“A loud noise was heard from the vicinity of the port wing landing gear during pushback of a Boeing 747-300 check details from the terminal at Sydney (Australia) airport. Inspection showed that one of the wing landing gear trunnion fork assemblies had failed. Detailed investigation revealed that the trunnion had failed by fatigue cracking. Deep machining grooves were found at the root of an internal radius that had not been shot-peened as required, and a chemical surface process during manufacture had resulted in shallow intergranular attack at the bottom of these grooves. It is probable that the critical cracking started from some of these grooves. In addition, the wall thickness at the failure location was significantly less than the minimum required in the drawings.\n\nSince the deep machining grooves, the lack of peening and the intergranular attack were all consequences of manufacturing, the fatigue cracking probably started shortly Selleck CBL0137 after the component entered service. This implies that fatigue cracking was present during all the trunnion
overhauls, but was not detected by non-destructive inspections during the overhauls. Quantitative fractography was used to produce a crack growth curve based on fracture surface markings thought to represent the overhaul timings. The crack growth curve suggested that the fatigue cracking was large enough to be detected by inspection during the last overhaul, if not the one before. However, it was probably not easy to detect the cracking. This investigation therefore highlights the difficulties that can be encountered when
inspection is the last (or only) line of defence against failure owing to unexpected manufacturing Smoothened Agonist order deficiencies. Crown Copyright (C) 2013 Published by Elsevier Ltd. All rights reserved.”
“Study Design. A study on acute low back pain (LBP) in consecutive working patients in a multicenter study in general practice. Objective. LBP costs are enormous in all countries. New guidelines are diffi cult to introduce. On the basis of a new, specially developed LBP scale, the aims were to predict the duration of sick leave (SL), and to examine if the guidelines concerning bed rest (BR) and referral to radiographical examination were followed. Summary of Background Data. Pain intensity and heavy work infl uence the course of SL. A fi nger-to-fl oor distance test assesses the mobility of the spine, and both the fi nger-to-fl oor distance test and the straight leg raising test (SLRT) can be used to predict the course of LBP. BR or waiting time for treatment or referral will prolong SL.
