Compliance with environmental protection regulations, in particular, community noise requirements, constitutes one of the major obstacles for designing REFRIGERATION future supersonic civil aircraft.Although there are several noise sources that contribute to the total noise level of supersonic aircraft, it is the turbulent jet that appears most pro
Prey REFRIGERATION size is an important factor in food consumption.In studies of feeding ecology, prey items are usually measured individually using calipers or ocular micrometers.Among amphibians and reptiles, there are species that feed on large numbers of small prey items (e.g.ants, termites).This high intake makes it difficult to estimate prey
Hyperspectral sensor technology has been advancing in recent years and become more practical to tackle a variety of applications.The arising issues of data transmission and storage can be addressed with the help of compression.To minimize the loss of important information, high spectral correlation between adjacent bands is exploited.In this paper,
Abstract Background In causal analyses, some third factor may distort the relationship between the exposure and the outcome variables under study, which gives spurious results.In this case, treatment groups and control groups that receive and do not receive the exposure are different from one another in some other essential variables, called confou
Whilst attention has been focussed on combating priority weeds we have neglected to obtain an overall picture of our weed flora.To rectify the position a National Weed List has been compiled, the weeds have been classified and an analysis made of the weed flora.Aspects covered in this paper are: major taxa, exotic and indigenous species and kinds o
