During the downward stroke advair diskus 100mcg discount asthma xanax, the center of the wings traverses a vertical distance d (see Fig cheap advair diskus 500mcg mastercard asthmatic bronchitis benzonatate. The total work done by the insect during each downward stroke is the product of force and distance generic advair diskus 250 mcg without a prescription definition of asthma exacerbation; that is order advair diskus 500 mcg with mastercard asthmatic bronchitis with hyperpyrexia, Work Fav d 2Wd (6. Our insect makes 110 down- ward strokes per second; therefore, its power output P is 4 3 P 112 erg 110/sec 1. To obtain the moment of inertia for the wing, we will assume that the wing can be approximated by a thin rod pivoted at one end. The maximum angular velocity max can be calculated from the maximum linear velocity vmax at the center of the wing vmax max (6. When the wings are decelerated toward the end of the stroke, this energy must be dissipated. During the downstroke, the kinetic energy is dissipated by the muscles themselves and is converted into heat. The wing joints of these insects contain a pad of elastic, rubberlike protein called resilin (Fig. The kinetic energy of the wing is converted into potential energy in the stretched resilin, which stores the energy much like a spring. Using a few simplifying assumptions, we can calculate the amount of energy stored in the stretched resilin. Although the resilin is bent into a com- plex shape, we will assume in our calculation that it is a straight rod of area A and length. Furthermore, we will assume that throughout the stretch the resilin obeys Hookes law. This is not strictly true as the resilin is stretched by a considerable amount and therefore both the area and Youngs modulus change in the process of stretching. Typically, in an insect the size of a bee the volume of the resilin may be equivalent to a cylinder 2 102 cm long and 4 104 cm2 in area. We will assume that the length of the resilin rod is increased by 50% when stretched. Experiments show that as much as 80% of the kinetic energy of the wing may be stored in the resilin. The hind legs of the ea, for exam- ple, also contain resilin, which stores energy for jumping (see Exercise 6-3). Compute the force on the body of the insect that must be generated during the downward wing stroke to keep the insect hovering. Referring to the discussion in the text, compute the point of attachment to the wing of muscle B in Fig. Assume that the shape of the resilin in each leg of the ea is equivalent to a cylinder 2 102 cm long and 104 cm2 in area. If the change in the length of the resilin is 102 cm, calculate the energy stored in the resilin. How large would these pads have to be in order for them to store 1 enough energy for a m jump? In the next three chapters, we will discuss the behavior of liquids and gases, both of which play an important role in the life sci- ences. The dierences in the physical properties of solids, liquids, and gases are explained in terms of the forces that bind the molecules. In a solid, the molecules are rigidly bound; a solid therefore has a denite shape and vol- ume. The molecules constituting a liquid are not bound together with su- cient force to maintain a denite shape, but the binding is suciently strong to maintain a denite volume. Therefore a gas has neither a denite shape nor a denite volumeit completely lls the vessel in which it is contained. Fluids and solids are governed by the same laws of mechan- ics, but, because of their ability to ow, uids exhibit some phenomena not found in solid matter. In this chapter we will illustrate the properties of uid pressure, buoyant force in liquids, and surface tension with examples from biology and zoology. When a force is applied to one section of a solid, this force is transmitted to the other parts of the solid with its direction unchanged. Because of a uids ability to ow, it transmits a force uniformly in all directions. A uid in a container exerts a force on all parts of the container in contact with the uid. The pressure in a uid increases with depth because of the weight of the uid above. In a uid of constant density, the dierence in pressure, P2 P1, between two points separated by a vertical distance h is P2 P1 gh (7. The relationship between the torr and several of the other units used to measure pressure follows: 1 torr 1mmHg 13. Because the pressure throughout the uid is the same, the force F2 acting on the area A2 in Fig. There are, however, soft-bodied animals (such as the sea anemone and the earthworm) that lack a rm skeleton. For the purpose of understanding the movements of an animal such as a worm, we can think of the animal as consisting of a closed elastic cylinder lled with a liquid; the cylinder is its hydrostatic skeleton. The worm pro- duces its movements with the longitudinal and circular muscles running along the walls of the cylinder (see Fig. Because the volume of the liquid in the cylinder is constant, contraction of the circular muscles makes the worm thinner and longer. Contraction of the longitudinal muscles causes the animal to become shorter and fatter. If the longitudinal muscles contract only on one side, the animal bends toward the contracting side. By anchoring alternate ends of its body to a surface and by producing sequential longitudinal and cir- cular contractions, the animal moves itself forward or backward. Assume that the circular muscles running around its circumference are uniformly distributed along the length of the worm and that the eective area of the muscle per unit length of the worm Section 7. The force Ff in the forward direction generated by this pressure, which stretches the worm, is 2 4 Ff P r 1. We will now use Archimedes principle to calculate the power required to remain aoat in water and to study the buoyancy of sh. If its density is greater than that of water, the animal must perform work in order not to sink. We will calculate the power P required for an animal of volume V and density to oat with a fraction f of its volume submerged. This motion accelerates the water downward and results in the upward reaction force that supports the animal. If the area of the moving limbs is A and the nal velocity of the accelerated water is v, the mass of water accelerated per unit time in the treading motion is given by (see Exercise 7-1) m Avw (7. The force producing this change in the momentum is applied to the water by the moving limbs.
Also buy advair diskus 100 mcg otc asthma treatment devices, the greater the range of measurements the better the agreement will appear to be 250 mcg advair diskus free shipping asthma lung cancer. It is preferable to plot the difference between the methods (A B) against (A + B)/2 advair diskus 250mcg with mastercard asthma video, the average order 250 mcg advair diskus asthma facts. From this type of plot it is much easier to assess the magnitude of disagreement (both error and bias), spot outliers, and see whether there is any trend, for example an increase in A B for high values. This way of plotting the data is a very powerful way of displaying the results of a method comparison study. It is closely related to the usual plot of residuals after model fitting, and the patterns observed may be similarly varied. With independence the methods may be compared very simply by analysing the individual A B differences. The mean of these differences will be the relative bias, and their standard deviation is the estimate of error. Also shown is a histogram of the individual between-method differences, and superimposed on the data are lines showing the mean difference and a 95 per cent range calculated from the standard deviation. If there is an association between the differences and the size of the measurements, then as before, a transformation (of the raw data) may be successfully employed. In this case the 95 per cent limits will be asymmetric and the bias will not be constant. Additional insight into the appropriateness of a transformation may be gained from a plot of |A B| against (A + B)/2, if the individual differences vary either side of zero. In the absence of a suitable transformation it may be reasonable to describe the differences between the methods by regressing A B on (A + B)/2. For replicated data, we can carry out these procedures using the means of the replicates. We can estimate the standard deviation of the difference between individual measurements from the standard deviation of the difference between means by var(A B) = n var( A B ) where n is the number of replicates. Within replicated data it may be felt desirable to carry out a two-way analysis of variance, with main effects of individuals and methods, in order to get better estimates. Such an analysis would need to be supported by the analysis of repeatability, and in the event of the two methods not being equally repeatable the analysis would have to be weighted appropriately. We can use regression to predict the measurement obtained by one method from the measurement obtained by the other, and calculate a standard error for this prediction. This is, in effect, a calibration approach and does not directly answer the question of comparability. There are several problems that can arise, some of which have already been referred to. Regression does not yield a single value for relative precision (error), as this depends upon the distance from the mean. If we do try to use regression methods to assess comparability difficulties arise because there no obvious estimate of bias, and the parameters are difficult to interpret. Unlike the analysis of variance model, the parameters are affected by the range of the observations and for the results to apply generally the methods ought to have been compared on a random sample of subjects - a condition that will very often not be met. The problem of the underestimation (attenuation) of the slope of the regression line has been considered by Yates (Healy, 1958), but the other problems remain. Comparison of two methods of measuring left ventricular ejection fraction (Carr et al. Other methods which have been proposed include principal component analysis (or orthogonal regression) and regression models with errors in both variables (structural relationship models) (see for example Carey et al. The considerable extra complexity of such analysis will not be justified if a simple comparison is all that is required. This is especially true when the results must be conveyed to and used by non-experts, e. Such methods will be necessary, however, if it is required to 315 predict one measurement from the other - this is nearer to calibration and is not the problem we have been addressing in this paper. The majority of medical method comparison studies seem to be carried out without the benefit of professional statistical expertise. Because virtually all introductory courses and textbooks in statistics are method-based rather than problem-based, the non-statistician will search in vain for a description of how to proceed with studies of this nature. It may be that, as a consequence, textbooks are scanned for the most similar-looking problem, which is undoubtedly correlation. Correlation is the most commonly used method, which may be one reason for so few studies involving replication, since simple correlation cannot cope with replicated data. A further reason for poor methodology is the tendency for researchers to imitate what they see in other published papers. So many papers are published in which the same incorrect methods are used that researchers can perhaps be forgiven for assuming that they are doing the right thing. It is to be hoped that journals will become enlightened and return papers using inappropriate techniques for reanalysis. Another factor is that some statisticians are not as aware of this problem as they might be. A counter-example is the whole chapter devoted to method comparison (by regression) by Strike (1981). More statisticians should be aware of this problem, and should use their influence to similarly increase the awareness of their non- statistical colleagues of the fallacies behind many common methods. A simple approach to the analysis may be the most revealing way of looking at the data. There needs to be a greater understanding of the nature of this problem, by statisticians, non-statisticians and journal referees.
