Figure 14-4 Silicon as a photon-sensitive substrate in a CCD imager. The sketch shows the effect of incident photons of various wavelengths on the silicon matrix of a CCD. Incident photons interact with the silicon, breaking covalent bonds between the silicon atoms and generating electrons and electron-deficient sites called electron holes. A voltage potential applied across the CCD holds the accumulating photoelectrons in the silicon matrix until they are read off from the chip and digitized. Red photons penetrate deeper into the matrix than blue photons, accounting for the relative insensitivity of silicon to blue light. High-energy X rays and cosmic rays disrupt many bonds and generate large saturating signals; typically, there are a few cosmic ray hits on the CCD surface per minute. Thermal energy, represented by the candle, also disrupts bonds and generates electrons (thermal noise) that cannot be distinguished from photoelectron counts; however, the problem can be reduced significantly by cooling the CCD to very low temperatures. After the electron charge packets are read off from the CCD surface, the structure of the silicon matrix is restored and the CCD is ready for another exposure.

Homeostatic processes may operate at different levels of biological organisation. Classically, homeostasis is used at the physiological level to denote adjustment to perturbation without a resultant reduction in tness to survive. However, it can also be used at the cell, population and community level, because each level has the ability to absorb change although, at the population level, there may be a cost in terms of reduced tness to survive. Density-dependent mechanisms compensating for reduction in recruitment may provide enough time for a population to adapt to pollutants. Such adaptations have been demonstrated in a number of vertebrate and invertebrate aquatic species. This genotypic adaptation is generally manifested through the development of tolerance to particular pollutants. However, with adaptation comes a cost to tolerance which may impact the future tness of the population. Additionally, there may be signi cant survival consequences for populations exhibiting reduced heterozygosity, such as those populations showing tolerance, if impacted by additional environmental stressors.

A number of medical and surgical treatment options exist for VIN (HPV related). However, invasive disease must be excluded initially before initiating any therapy. In a study of 73 women with VIN III on biopsy treated with surgical resection reported by Modesitt and associates, 22% had an underlying squamous vulvar cancer.22 For patients whose specimen showed residual VIN III at the surgical margins, 46% recurred compared to 17% of patients with negative margins.
