Theoretical Molecular Biophysics

"Theoretical Molecular Biophysics" is a complicated examine ebook for college kids, almost immediately earlier than or after finishing undergraduate reviews, in physics, chemistry or biology. It presents the instruments for an knowing of trouble-free approaches in biology, resembling photosynthesis on a molecular point. A easy wisdom in mechanics, electrostatics, quantum thought and statistical physics is fascinating.

Mathematical Theory of Electrophoresis

The improvement of latest molecular biology with its starting to be tendency towards in-depth learn of the mechanisms of organic tactics, constitution, functionality, and id of biopolymers calls for software of exact physicochemical equipment. Electrophoresis occupies a key place between such equipment.

Interpreting Biomedical Science: Experiment, Evidence, and Belief

Reading Biomedical technological know-how: test, proof, and trust discusses what can get it wrong in organic technological know-how, delivering an impartial view and cohesive knowing of clinical tools, records, information interpretation, and clinical ethics which are illustrated with useful examples and real-life functions.

8) are identical mathematically, and they produce the same value for the elimination rate constant. 7). In Chapter 8, concepts related to the shelf-life determination of drug products are introduced. One area of concern is the effect of a change in storage temperature on the stability of a drug. One equation uses the logarithm of the ratio of a degradation rate constants at two different temperatures: log(k2 /k1 ). 236 min−1 Since drug degradation occurs with faster rates at higher temperatures than at lower ones, k2 must occur at a temperature much higher than that observed with k1 .

16) is the form of a second-order partial derivative. 31 × 10−23 η−2 r −2 In thermodynamics (see Chapter 2), a change of volume of an ideal gas at a constant temperature does not result in a change in the internal energy of the system. 19) And for 1 mol of an ideal gas (n = 1), (∂V /∂T )P = R/P = constant (Adamson, 1969). 6 EXPANDING AND REDUCING FORMULAS Pharmacists and pharmaceutical scientists are often asked to prepare volumes or quantities different from those given in a prescription or formula.

GLOSSARY API Dalton’s law of partial pressure Density of an ideal gas DSC Einstein’s equation Active pharmaceutical ingredient. For a mixture of gases confined to a rigid container with volume V maintained at a constant temperature, the total pressure exerted by all the gases equals the sum of all the partial pressures of the gases.
