Colchicine, a well-known alkaloid isolated from Colchicum autumnale, interferes with microtubule growth and, therefore affects mitosis and other microtubule dependent functions. We have been interested in the structural requirements of colchicine for tubulin recognition. In particular our interests have been focused on the active colchicine conformation with respect to the pivot bond joining the A

This paper deals with bandwidth allocation in a Bluetooth scatternet. The proposed assignment of transmission rights provides a controlled traffic transfer between Bluetooth piconets and represents a key component in an ad-hoc wireless Bluetooth network in order to provide with efficient data packet passing within and across piconets. This assignment is obtained by executing a distributed algorith

Boken beskriver hur man på ett kostnadseffektivt sätt minskar risken för avbrott i flödet av varor och tjänster mellan olika led i försörjningskedjan samt säkerställer en snabb återgång till ett stabilt flöde om ett avbrott trots allt inträffar. Ämnesmässigt hamnar boken inom områdena Risk Management, Business Continuity Management och Supply Chain Risk Management. Boken ger läsaren kunskaper om h

Den biologiska psykologin har under senare år, tillsammans med andra vetenskaper som rör hjärnan, utvecklats till ett mycket aktivt och framgångsrikt forskningsområde. I detta kapitel kommer vi ofta att röra oss i gränsområden till andra vetenskaper - som utvecklingslära, genetik, neurofysiologi och neurokemi - för att presentera en karta över detta expansiva område.

The question of how to lead a happy and meaningful life has been at the heart of philosophical debate since time immemorial. Today, however, these questions seem to be addressed not by philosophers but self-help gurus, who frantically champion the individual's quest for self-expression and self-realization; the desire to become authentic. Against these new age sophistries, How to Stop Living and S

In Sweden, municipalities organize a large share of public services but the conditions for providing these services differ considerably due to differences in size and wealth. In the wake of financial stress and New Public Management reforms the Swedish local governments seeks new ways to make both ends meet and still manage the services to be in line with the present (not the past) demands of the

The multihadron production in the reaction e(+)e(-) -> e(+)e(-) + hadrons has been studied for the first time at LEP2 energies with both scattered e(+) and e(-) detected at very low Q(2), measured by the DELPHI VSAT. A reasonable agreement between data and full simulation is demonstrated and the total gamma gamma hadronic cross-section is estimated for the gamma gamma center of mass energy up to 1

Conditions are presented for when estimated demand systems automatically satisfy adding up. It is shown that there exist nonlinear demand systems (such as the Almost Ideal Demand System) where adding up is allowed in the model, but where it is not automatically satisfied for the LS and SUR estimates. In these situations it is possible to test the applicability of the model as regards adding up. Th

This article explores why and how a minority social movement persists despite persistent constraints placed upon it by a majority-dominated State. The Chinese education movement has been one of the largest, longest, and most sustained social movements in Malaysia. Sociological, economic, and demographic changes of the Chinese community along with domestic political struggles revolving around the e
