13. Mdba : uma arquitetura para administração remota de banco de dados em ambientes de computação ubíqua
Advances in Mobile Computing have provided users with access to services and information at any place and any time. Nowadays, it is possible for users to have high mobility and to access any databases (DBs), residing in fixed or mobile computers. However, databases residing in mobile computers, called mobile databases, need to be managed by tools that addres

15. 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

16. SESAMO : um controlador de concorrência que implementa a serialidade semântica de forma descentralizada em sistemas de bancos de dados múltiplos com suporte a mobilidade
In a mobile multidatabase system, there is a collection of autonomous, distributed, heterogeneous and mobile component database systems which are interconnected by means of a wireless network. In such an environment, each network node can access multiple databases of that collection by means of global transactions whose concurrency is managed by a scheduler,

17. EFEITOS DE DIFERENTES REGIÕES URBANAS NA PROPAGAÇÃO DE SINAIS DE SISTEMAS DE COMUNICAÇÕES PESSOAIS BASEADOS EM REDES DE SATÉLITES NÃO GEOESTACIONÁRIOS / EFFECTS OF DIFFERENT URBAN ENVIRONMENTS ON THE PROPAGATION OF SIGNALS FROM PERSONAL COM. SYSTEMS BASED ON NON GEOSTATIONARY ORBIT SATELLITE NETWORKS
As land-mobile satellite systems and radio-determination systems get more importance in the global telecommunications scenario, it becomes even more necessary to understand the radio-propagation environment: its behavior and the inter-relationship between its several aspects and physical parameters. Due to the communications devices characteristics used in t

18. A tecnologia da informação como gestora da hiperconectividade em prol do trabalho cooperativo.
The current scene of the Information Technology (IT) points a trend of integration of the heterogeneous databases and the emergency of a model of cooperative work between groups in corporative environments. An increasing demand of the users perceived in the groups that use of devoid applications business-oriented of bigger freedom and flexibility in the use

19. AMDB - An Approach for Sharing Mobile Databases
Mobile Database Community (MDBC) is a dynamic collection of autonomous mobile databases, in which each database user can access each other s database in the community through a wireless communication infrastructure. Such communities can be formed opportunistically over mobile database hosts in ad hoc configurable envi-ronments. New participants may join to a

20. AMDB - An Approach for Sharing Mobile Databases
Uma Comunidade de Bancos de Dados Móveis (MDBC) representa uma coleção de bancos de dados móveis e autônomos. Em tal contexto, cada usuário de um sistema de banco de dados participante da comunidade pode acessar os outros bancos de dados através de uma infra-estrutura de comunicação sem fio. Esta dissertação pro-põe uma arquitetura chamada AMDB (

21. A New, Expressed Multigene Family Containing a Hot Spot for Insertion of Retroelements Is Associated with Polymorphic Subtelomeric Regions of Trypanosoma brucei
We describe a novel gene family that forms clusters in subtelomeric regions of Trypanosoma brucei chromosomes and partially accounts for the observed clustering of retrotransposons. The ingi and ribosomal inserted mobile element (RIME) non-LTR retrotransposons share 250 bp at both extremities and are the most abundant putatively mobile elements, with about 5

22. An estimate of large-scale sequencing accuracy
The accuracy of large-scale DNA sequencing is difficult to estimate without redundant effort. We have found that the mobile genetic element IS10, a component of the transposon Tn10, has contaminated a significant number of clones in the public databases, as a result of the use of the transposon in bacterial cloning strain construction. These contaminations n

23. ACLAME: A CLAssification of Mobile genetic Elements
The ACLAME database (http://aclame.ulb.ac.be) is a collection and classification of prokaryotic mobile genetic elements (MGEs) from various sources, comprising all known phage genomes, plasmids and transposons. In addition to providing information on the full genomes and genetic entities, it aims to build a comprehensive classification of the functional modu

24. A Multicomponent System Is Required for Tetracycline-Induced Excision of Tn4555
Bacteroides spp. are the predominant organisms in the intestinal tract, and they also are important opportunistic pathogens. Antibiotic therapy of Bacteroides infections often is complicated by the prevalence of drug-resistant organisms which acquire resistance genes from a variety of mobile genetic elements including conjugative transposons (CTns) and mobil
