When analyzing the relationship between the detergent used for cleaning the churns (2=2.445, p=0.118), the period of use (2=0.224, p=0.636), the type of water (2=0.087, p=0.767) and the presence of the micro-organism, any statistically significant association was found as can be seen on table 2.
In a research carried out in three farms where the presence of the bacterium was evidenced, it was possible to control its growth by continuously washing the churns with an alkaline detergent (8).
look the part,” said Sean Smith Detectamet's CEO.
are a hot item among collectors, so much so that innumerable replicas are now being made.
For a couple of hundred pounds you can buy machines which churn
and freeze, but will still take a while to churn
down fully but are a lot better than the cheaper ones.
In the few hundred years prior to the industrialization of butter making, cream was cultured before it was churned
. Culturing was the consequence of the universal practice of accumulating multiple milkings before churning.
(Of course, a decade of Beancounter Bingo has churned
most of those positions right out of existence, but that's another column.)
All three groups, who describe their work in the September BIO/TECHNOLOGY, say the new findings illustrate the potential of harnessing transgenic livestock to produce drugs more rapidly, more cheaply and in greater quantities than the standard "bioreactor" approach, in which vats of gene-altered bacteria or culture dishes of animal cells churn
out genetically engineered drugs.
Items that have already been confirmed for the next sale include copper milk churns
, butter churns
, a 1947 David Brown Crop Master, a 1958 Fordson Dexter, a 1954 Diesel Nuffield and a stone roller.
The plates float on the fiery-hot mantle, the thickest layer of Earth, which churns
around us like gooey taffy.
In recent years, researchers have recognized that the hydrothermal vents at the spreading ridges--where rising lava churns
out new seafloor--play an important role in the exchange of chemicals and heat between the oceans and the crust (SN: 12/20&27/86, p.389).
