Comment on ``Spin-glass transition of the three-dimensional Heisenberg spin glass''
Campos et al. [Phys. Rev. Lett. 97 (2006) 217204] claim that in the 3d
Heisenberg Spin Glass, chiral and spin sector ordering temperatures are
identical. We point out that in their analysis of their numerical data key
assumptions are made which are unjustified.Comment: published versio
Australian Vessel Performance in the East Coast Tuna Longline Fishery
A sample of daily observations on the activities of Australian vessels longlining for yellowfin tuna, Thunnus albacares, during 1987-90 was analyzed, using a production junction approach, to determine the effects of vessel characteristics and operational practices and conditions. Significant differences were found between the tuna fisheries in the northern and southern regions of the inshore yellowfin tuna fishery in the east Australian Exclusive Economic Zone. The type of vessel used, and fishing practices such as soaktime, patrolling the longline, and choice of surface water temperature were found to have significant effects on yellowfin tuna catch rates
Effects of the thermal sterilization procedure on polymeric products
Properties of samples are tested, after thermal exposure, and values are compared with unexposed samples. Thermal stability or compatibility ratings of formulated or compounded organic polymers using trade names are made and degree of change in measured properties is assessed. Products are rated compatible, marginal, or not compatible
