  • A useful aspect of freshwater sponge biology, particularly for the purposes of an undergraduate lab module, is the fact that they enter diapause as small gemmules. Gemmules are overwintering balls that are produced in the late summer/early fall by the adult sponge. They are the size of the period at the end of this sentence. Adult tissue disintegrates around the gemmule during the winter, and a new sponge emerges from the gemmules in the spring. The newly developing sponge exits the gemmule from a micropyle, and then quickly spreads around the gemmule. In a...

Since real estate is purchased today based on its ability to produce cash flow in the future, tools are needed which help calculate the present value of future cash flows. These tools are readily available, are discussed in Tool Kits #2 and #3, and involve the concept of “capitalization”. All capitalization tools convert future income...

  • This section illustrates that MBT systems can be described as two simple concepts: either to separate the waste and then treat; or to treat the waste and then separate. In some systems only biological treatment is required to treat all the residual MSW before disposal to landfill. Whilst a variety of treatment and mechanical separation options are offered, these need to be optimised in terms of the outputs in order to find outlets for the various materials / fuels derived from the process (see Markets for the Outputs section). ...

  • I started my first photobiological research project almost exactly 50 years ago, in the spring of 1957. My scientific interest ever since has been focused on photobiology in its many aspects. Because I have been employed as a botanist, my own research has dealt with the photobiology of plants, but throughout this time I have been interested in other aspects, such as vision, the photobiology of skin, and bioluminescence. A first edition of the present book was published in 2002, but this second edition is much expanded and completely updated.
