Between controllers

Sufficient numbers of control animals should be employed. The use of such controls allows a determination of normal values for features monitored ki the study and background kicidence of pathology ki the population studied detection of the onset of adverse conditions, eg, infection, which are unrelated to, and detrimental to, the conduct of the study and deviation of monitored features between controls and exposed animals, which may kidicate a treatmentrelated effect. 

Knowing what devices are used for product verification purposes so that you can distinguish between controlled and uncontrolled devices - you will need to maintain a list of devices for this purpose.

Table 19.S). In particular, they have established that the presence of dissolved O2 enhances passivity thus causing E, to become more positive, and consider that this explains the failure of France and Greene to obtain accord between controlled potential tests in hydrogen-saturated chloride solutions and immersion tests in oxygenated chloride solutions at the same potentials. 

In a field residue study, commodities are grown on control plots located near the plots used to produce commodities treated with test substance. Care is taken to ensure that the only difference between control and treated commodities is that the former does not receive application of the pesticide and the latter does. Crop variety and growing conditions (including geographical location, soil, time of year, weather, etc.) are essentially identical for the control and the treated commodities.

MRI), but this has not been reported for participants who solely use cannabis on a regular chronic basis. A number of electroencephalogram (EEG) studies have found no differences between controls and chronic cannabis users for either awake or sleeping EEG patterns (Rodin et al., 1970 Stefanis et al., 1977).

AUTO. This is the normal position of the M-A transfer switch. It places the controller in the automatic mode of operation. Also, the deviation meter indicates any deviation between controlled variable and setpoint. 

Figure 2 reports the time dependent germination pattern of radish seeds in the presence and absence of rue extract. Although the germination curves have the same general shape, important differences between control and treated seeds are evident. In fact, the rue extract induces a delay in the onset and a decrease in the rate of germination.

The major elements Mg, Ca, Al, K does not presented significant differences between the areas showing some independency of mining effects in these soil-plant systems. Phosphorus presents a different behavior between control and mining areas what may be related with parent material differences or plant physiology. 

Typically, comparison of incidences of any one type of lesion between controls and treated animals are made using the multiple 2x2 chi square test or Fisher s exact test with a modification of the numbers of animals as the denominators. Too often, experimenters exclude from consideration all those animals (in both groups) that died prior to the first animals being found with a lesion at that site. 

Ittner s analysis displays the familiar contrast between control and knowledge which often demarcated the engineer s work from that of the scientist. But, more specifically, it also denies any role to unit processes defined as chemical processes. For Ittner, the unit process, once it is examined closely, can be... 

In another study, when the age range was limited to 30 to 60 years, the difference in serum Lp(a) concentrations between controls and patients with cerebrovascular disease was highly significant, perhaps indicating that Lp(a) plays an important role in the development of premature cerebrovascular atherosclerosis (J7). 

An obvious difference was also noted between control and induced skate hepaticdnicrosomal AHH activity in the presence of a-naphthoflavone (10 M). This compound, when added in vitro at this or higher concentrations, caused significant stimulation of AHH activity in control animals (about 3-fold) but inhibition (80%) was found in DBA-pretreated skates. Similar results were earlier reported for control and 3-methylcholanthrene-treated rats (23), where it appears that the response is due to differential effects of a-naphthoflavone on hepatic microsomal cytochrome P-450 (stimulated) and cytochrome P-448 (inhibited) (24). Our data suggests that there may be a novel form of cytochrome P-450 synthesized in skate liver in response to polycyclic hydrocarbon administration, even though there was no hypsochromic shift in the carbon monoxide difference spectrum of dithionite reduced hepatic microsomes from DBA-treated skates (relative to hepatic microsomes from control fish).
