  • The current control problems present natural trend of increasing its complexity due to performance criteria that is becoming more sophisticated. The necessity of practicers and engineers in dealing with complex dynamic systems has motivated the design of controllers, whose structures are based on multiobjective constraints, knowledge from expert, uncertainties, nonlinearities, parameters that vary with time, time delay conditions, multivariable systems, and others.

  • Pest and disease management continues to be an important challenge to the agricultural community. Confronted with the shifts in pest pressure and the rise in new pest and crop problems, coupled with public concern over pesticide use and more stringent environmental regulations, today’s crop producer must exhibit good stewardship and stay current with new technologies in order to produce high-quality crops in a profitable manner.

  • Developmental biology studies the process by which organisms grow and develop. Originating in embryology, modern developmental biology studies the genetic control of cell growth, differentiation, and "morphogenesis," which is the process that progressively gives rise to tissues, organs, and anatomy. Model organisms for developmental biology include the round worm Caenorhabditis elegans,[39] the fruit fly Drosophila melanogaster,[40] the zebrafish Danio rerio,[41] the mouse Mus musculus,,[42] and the weed Arabidopsis thaliana.

  • Intellectual property (IP) rights are a source of hidden wealth worth trillions of dollars, and they impose hidden costs on the same scale. The rules of intellectual property range from confusing to nearly incomprehen- sible, and the professional practitioners who manage these rights sometimes seem to belong to a secret society. … The IP system also determines when and how an innovation becomes available for others to use by defin- ing boundaries around what is accessible and what is not.

  • Flowering plants now dominate the terrestrial ecosystems of the planet, and there are good reasons for supposing that the flower itself has been a major contributing factor to the spread of the Angiosperms. Although the Angiosperm flower is based on four whorls of organs – petals, sepal, stamens and carpels – the 300 000 odd species exhibit a huge array of different floral morphologies. Consider, e.g., the humble periwinkle flower and contrast it with the complex passion flower.

  • Tuberculosis is transmitted from person to person by respiratory droplets. Although some people develop active tuberculosis disease after infection, almost all tuberculosis infections are asymptomatic and remain latent. Latent tuberculosis infection (LTBI) itself progresses to active disease in approximately 5% to 10% of infected persons. The rate of progression is much greater in immunocompromised individuals. The estimated 2 billion people living with LTBI represent a vast reservoir of potential cases of tuberculosis around the world.

  • The heterologous expression of tryptophan trytophylquinone (TTQ)-dependent aromatic amine dehydrogenase (AADH) has been achieved in Paracoccus denitrificans. The aauBEDAgenes andorf-2from the aromatic amine utilization (aau) gene cluster of Alcaligenes faecaliswere placed under the regulatory control of themauFpromoter fromP. denitrificans and introduced intoP. denitrificansusing a broad-host-range vector.

  • The classical metabolic control theory [Kacser, H. & Burns, J.A. (1973)Symp.Soc.Exp.Biol. 27, 65–104; Heinrich, R. & Rapoport, T. (1974)Eur. J. Biochem.42, 89–95.] does not take into account experimental evidence for correlations between enzyme concentrations in the cell. We investigated the implications of two causes of linear correlations: competition between enzymes, which is a mere physical adaptation of the cell to the limitation of resources and space, and regulatory correlations, which result from the existence of regulatory networks....

  • Since the beginning of human history, people have wondered how traits are inherited from one generation to the next. Although children often look more like one parent than the other, most offspring seem to be a blend of the characteristics of both parents. Centuries of breeding of domestic plants and animals had shown that useful traits - speed in horses, strength in oxen, and larger fruits in crops - can be accentuated by controlled mating. However, there was no scientific way to predict the outcome of a cross between two particular parents. ...

  • A preliminary study was carried out in mid 1999 on the status and potential impact of the introduction of exotic fish species in the Mekong Basin. Introductions have been made for four main purposes: aquaculture, stocking into lakes and reservoirs, pest control (mosquito) and the aquarium fish trade. Introductions of exotic species and movements of large quantities of fish for stocking are accompanied by risks to the environment, the possibility of native fish species declining through competition, predation or genetic interference, and the possible spread of disease....

  • Science arises from the very human desire to understand and control the world. Over the course of history, we humans have gradually built up a grand edifice of knowledge that enables us to predict, to varying extents, the weather, the motions of the planets, solar and lunar eclipses, the courses of diseases, the rise and fall of economic growth, the stages of language development in children, and a vast panorama of other natural, social, and cultural phenomena. More recently we have even come to understand some fundamental limits to our abilities to predict.
