curve

 [kerv]
a line that is not straight, or that describes part of a circle, especially a line representing varying values in a graph.
dose-effect curve (dose-response curve) a graphic representation of the effect caused by an agent (such as a drug or radiation) plotted against the dose, showing the relationship of the effect to changes in the dose.
growth curve the curve obtained by plotting increase in size or numbers against the elapsed time.
oxyhemoglobin dissociation curve a graphic curve representing the normal variation in the amount of oxygen that combines with hemoglobin as a function of the partial pressures of oxygen and carbon dioxide. The curve is said to shift to the right when less than a normal amount of oxygen is taken up by the blood at a given Po2, and to shift to the left when more than a normal amount is taken up. Factors influencing the shape of the curve include changes in the blood pH, Pco2, and temperature; the presence of carbon monoxide; alterations in the constituents of the erythrocytes; and certain disease states.
pulse curve sphygmogram.
Spee curve (curve of Spee) the anatomic curvature of the occlusal alignment of teeth, beginning at the tip of the lower canine, following the buccal cusps of the premolars and molars, and continuing to the anterior border of the ramus.
strength-duration curve a graphic representation of the relationship between the intensity of an electric stimulus at the motor point of a muscle and the length of time it must flow to elicit a minimal contraction; see also chronaxie and rheobase. In cardiac pacing it is useful in determining characteristics of a particular pacing electrode and determining the most efficient selection of pacing parameters for an appropriate safety margin.
survival curve a graph of the probability of survival versus time, commonly used to present the results of clinical trials, e.g., a graph of the fraction of patients surviving (until death, relapse, or some other defined endpoint) at each time after a certain therapeutic procedure.

curve

(kerv),
1. A nonangular continuous bend or line.
2. A chart or graphic representation, by means of a continuous line connecting individual observations, of the course of a physiologic activity, of the number of cases of a disease in a given period, or of any entity that might be otherwise presented by a table of figures. Synonym(s): chart (2)
[L. curvo, to bend]
A nonangular deviation from a straight course in a line or surface

Patient discussion about curve

Q. I broke my pinkie finger a year ago. It is locked in a curved position. How can I straiten it out?

A. i would let a certified orthopedic look at the finger. treatment is according to the severity of the case. i think Terrany method is about finger physiotherapy. i'm not sure this method is to reshape uneven bone healing. this is a bit different situation, bone can be reshaped, this is how an orthodontic can move teeth- by changing the bone. but it takes a few years. i would go to an orthopedic, i advise you to do the same.

Figure 7, Figure 8, Figure 9 show a comparison of computation times for the proposed approaches against the original RO fitted curve. A negative difference indicates that the proposed method consumes lesser time when compared with the original curve and vice-versa.
To illustrate further the behavior of the four models compared in this study when fitted to the SWCC data for various soil types, the observed data and fitted curves are compared in Figures 2(a) to 2(x).
The fitted curve is represented on this plot as a horizontal line of zero deviation.
Hancock found that such fitted curves do not differ with statistical significance from a straight flat line and that they provide poor explanations for the variation in the observations as measured by the goodness-of-fit ([R.sup.2]).
The single-point estimates of the buffering capacity (O&[S.sub.SP] values) were all highly and linearly correlated with the values derived from the fitted curves (Fig.
And then all values of the fitted curve minus 19 to return to the original value.
Thereby the fitted curve was shown in Figure 6 and the relationship between CaC[O.sub.3] whisker and the peak stress was approximately a linear function.
We plot also the prediction bounds for the fitted curve. The prediction is based on the existing fit to our simulation calculations by using a 90 % 'probability of occurrence'.
The fitted curve is used instead of the large number of samples usually required; that is, instead of generating a large number of samples, a specific trend is identified from the curve using the available data.
The results of a typical fitted curve are compared with the experimental data in Figure 9.
Figure 4 is the fitted Phillips curve using the CPI, Figure 5 the fitted curve using the WPI.
