  • As currently taught, the introductory course in analytical chemistry emphasizes quantitative (and sometimes qualitative) methods of analysis coupled with a heavy dose of equilibrium chemistry. Analytical chemistry, however, is more than equilib- rium chemistry and a collection of analytical methods; it is an approach to solving chemical problems. Although discussing different methods is important, that dis- cussion should not come at the expense of other equally important topics.

  • Whereas the mechanical performance of plant organs has often been discussed in evolutionary biology [1,2], tree biomechanics has rarely been considered in the context of functional ecology. Functional ecology aims at understanding the functions of organisms that result in fluxes of biomass or energy within an ecosystem, e.g., a forest. This discipline studies the processes controlling these fluxes, at either the scale of an individual, community, or ecosystem, with their response to natural or anthropic environmental variations....

  • This book follows in the footsteps of two previous efforts—Snakes: Ecology and Evolutionary Biology (1987) and Snakes: Ecology and Behavior (1993)—to provide established and new researchers with a current synopsis of snake ecology. In the preface to each of these earlier works, one of us (R. A. S.) admitted that he had erred in assuming that another “Biology of the Serpentes” book was not worth tackling. And after the fi rst two books, we thought that perhaps yet another book was not needed—we were wrong again.

  • I conceived of the courses that led to this book on sabbatical in 1999–2000, during my time as the Mote Eminent Scholar at Florida State University and the Mote Marine Laboratory (a chair generously funded by William R. Mote, who was a good friend of science). While at FSU, I worked on a problem of life histories in fluctuating environments with Joe Travis and we needed to construct log-normal random variables of specified means and variances.

  • IHE ACS SYMPOSIUM SERIES was first published in 1974 to provide a mechanism for publishing symposia quickly in book form. The purpose of this series is to publish comprehensive books developed from symposia, which are usually "snapshots in time" of the current research being done on a topic, plus some review material on the topic. For this reason, it is necessary that the papers be published as quickly as possible. Before a symposium-based book is put under contract, the proposed table of contents is reviewed for appropriateness to the topic and for comprehensiveness of the collection.

  • The molecular analysis of human cancer is complicated by the difficulty in obtaining pure populations of tumor cells to study. One traditional method of obtaining a pure representation has been establishing cancer cell lines from primary tumors. However, this technique is time consuming and of low yield. Artifacts of cell culture include the selection of genetic alterations not present in primary tumors (1,2) and the alteration of gene expression as compared to primary tumors (3).

  • Consider the family of sensor routing protocols where each sensor communicates either directly or indirectly with a base station. In turn the base station correlates and aggregates information from each sensor. Accordingly, the base station will need to verify the authenticity of the sensor, the integrity of the communication and ascertain that it is not a replay of an earlier communication. Recall the assumption that the base station is computationally robust and secure. In our protocol each sensor j shares a unique 64 bit Key Key , with the base station.

  • Organisms subject to changing environmental conditions or experimental protocols show complex patterns of responses. The design principles behind these patterns are still poorly understood. Here, modular metabolic control analysis is developed to deal with large changes in branched pathways.

  • I have three vivid memories about learning statistics as an undergraduate that all involve misconceptions. Firstly, I remember my lecturer telling me that, after obtaining a result that was not statistically significant, I should conclude that timber harvesting did not have an effect (on what, I cannot remember). While the logic was flawed, I have since realized that it is a misconception shared by many ecologists.

  • The guidance assumes the presence of a trained health worker to administer the uterotonic, the medicine is used after childbirth for postpartum hemorrhage, and that 600 micrograms of misoprostol is administered. In low-resource settings, these conditions are not often met, which poses a disadvantage to the selection and use of misoprostol.

  • In this review, experimental studies were classified as RCTs when randomly allocated intervention groups were compared, where a distinct control group could receive either another treatment modality or 'no treatment'. Thus studies were eligible for inclusion if there was at least one arm with a PFMT protocol, alone or together with other adjunctive therapies, compared with either a control group of 'no treatment' or 'usual treatment' or a different PFMT protocol, alone or together with other adjunctive therapies (biofeedback, electrical stimulation or vaginal weights).

  • A wireless ad-hoc network is a wireless network deployed without any infrastructure. In such a network, there is no access point or wireless router to forward messages among the computing devices. Instead, these devices depend on the ad-hoc mode of their wireless network interface cards to communicate with each other. If the nodes are within the transmission range of the wireless signal, they can send messages to each other directly. Otherwise, the nodes in between will forward the messages for them. Thus, each node is both an end system and a router simultaneously....

  • Although the very first carbon offset project was voluntary, 2 much of the work to establish real markets for carbon offsets has been done in the context of designing regulatory programs. Many experimental carbon offset projects were undertaken in the 1990s, for example, in order to inform negotiations under the Framework Convention on Climate Change about the design of an international GHG emissions trading system.

  • Some people raised their eyebrows when I told them that I was writing a book on congestion control, and said, ‘Is this topic really large enough for a book?’ Well, it certainly is, and I am sure that it is needed. For example, there are quite a number of Ph.D. students out there who work in this field–yet, when they start out, they do not have a comprehensive introductory book about the subject. This book is for them and, of course, for anyone else with an interest in this fascinating topic–graduate students, teachers in academia and network administrators alike...
