Initially, animals were probably observed for practical reasons because early human survival depended on knowledge of animal behaviour.
In our study, a neurotoxicity induced by colistin was probably observed in 9 (12 %) and 7 (9.2 %) among AS and IV groups, respectively.
Comparing the h M heights (row 2) with h I heights (rows 4 and 5) for the Czech Republic measurements, we deduce that for f 0 = 3.59 MHz, the O mode is probably observed, whereas for f 0 = 4.65 and f 0 = 7.04 MHz, the X mode likely dominated, since h M = h I within the estimated uncertainties.
Potential effects of both treatments on this brain structure would be probably observed in older mouse lemur but further investigations will be necessary to confirm this hypothesis.
This was probably observed, as the vaccine protects against invasive infections with serotype 6B, but in addition the vaccine has been shown to have a high level of cross-protection against serotype 6A but not 6C [ 16].
We noted down the behavior of many individuals among the ones that we could see (since no attempt was made to mark them, some individuals were probably observed several times).
The lack of association between the risk factor for recurrence and the later tumor recurrence events is probably observed because of the limited number of urine samples included in this analysis (non-recurrent visits only).
The 2 fml−1 control limit was probably observed in most asbestos factories during the 1970s, and only four of the 512 male mesothelioma cases in our study had worked for more than 5 years in asbestos product manufacturing; but substantial asbestos exposure was widespread in the much larger workforce in construction.
However, studies have shown that aggressive interactions among group members do occur, and are probably not often observed because these interactions tend to be quick and silent.
At a later stage stress fibers are probably lost as observed most clearly in detached or more loosely adhered cells.
