2. PrÃ-seleÃÃo e prÃ-carga de dados para bancos de dados mÃveis
One of the main goals of mobile data access is to reach the ubiquity inherent to the mobile systems: to access information regardless of time and place. Due to mobile systems restrictions such as, for instance, limited memory and narrow bandwidth, it is only natural that researchers expend efforts to soothe such issues. This work will approach issues regardi

3. The determinants of HMO enrollment and growth.
This paper analyzes why HMO enrollment and growth have varied greatly among states. Using Tobit analysis, a number of variables are related to state HMO market share in 1976 and the change in HMO market share from 1966 to 1976. Higher hospital costs and mobile populations are shown to have encouraged HMO development. There is some evidence that the extent of

4. A Proposal of UML Extensions for Modeling of Applications in Mobile Environments for Service Oriented Applications / Uma Proposta de Extensões à UML para Modelagem de Aplicações em Ambientes Móveis para Aplicações Orientadas a Serviços
With the great growth of the use of mobile devices (laptop, palmtop, or some type Digital Personal Assistants (PDA)), a new paradigm computing appeared: the mobile computing. The new paradigm allows the users of that environment to have access to services independent of their location, in other words, it allows the mobility. They are being made several studi

8. The Alkali Ion-DNA Interaction as Reflected in the Nuclear Relaxation Rates of 23Na and 87Rb
Longitudinal relaxation rates of 23Na and 87Rb in aqueous solutions of DNA were measured and interpreted in terms of contributions of “bound” and free species. The frequency dependence of the 23Na relaxation rate sets an upper limit of 5.5 nsec for the correlation time characteristic of the alkali ion-DNA interaction. The plausible description of the alk
