BACKGROUND Data analysis in community health assessment (CHA) involves the collection, integration, and analysis of large numerical and spatial data sets in order to identify health priorities. Geographic Information Systems (GIS) enable for management and analysis using spatial data, but have limitations in performing analysis of numerical data because of its traditional database architecture....

Bi r th weight is in large extent influenced by gestational age. In addi tion genetic and envi ronmental factors determine intrauter ine growth and bi r th weight. The contr ibutions of these factors may be influenced by maternal smoking dur ing pregnancy. We examined bi r th weight and maternal smoking in a sample of 2930 twin pai rs from the Nether lands Twin Register using structural equatio...

The compatibility of an "animal lib­ eration" ethic and an environmental eth ic depends prima ri lyon how one interprets the meaning and moral structu re of a theory of envi ronmental ethics. In part this is because the meaning and moral structure of an animal liberation ethic is fairly straightforward: it focuses on the absence of morally relevant differences between humans and animals, and on...

Bioassay tests were carried out to investigate the susceptibility status of two (3rd and 4th) instar larvae of Culex quenquifasciatus Say populations of Dhaka city against two organophosphate (malathion and chloropyrifos) and two pyrithroid (cypermethrin and lambdacyhalothrin) insecticides. The LC50 values of malathion, chloropyrifos, cypermetrin and lambdacyhalothrin against the 3rd instar lar...

This paper describes the 3D GIS research efforts done by the GIS research groups as well as by major GIS software vendors world wide, namely Environmental System Research Institute (ESRI) Inc., ERDAS Inc., Integraph Inc., and PCI Geomatics Inc. Research works done by the authors of this paper formed major discussion of this paper including a discussion on why the 3D GIS software is difficult to...

The functionality of spatial process analysis is the foundation of GIS’s comprehensive application . To realize such a goal. it is desirable that not only the data model of GIS can represent the datasets needed by spatial process models, but also GIS is able to do multitemporal spatial analysis. But most of current GISs are static in essence, they cannot represent temporal information and tempo...

An organization’s strategies for managing Geographic Information Systems (GIS) play a crucial role in the success of the technology within the organization. As with any technological innovation, the key factor in GIS success is how it is applied to solve the organization’s business problems. Corporatewide strategies to introduce, implement, and operate the GIS determine how well it serves busin...

Gross chromosomal rearrangements (GCRs) play an important role in human diseases, including cancer. The identity of all Genome Instability Suppressing (GIS) genes is not currently known. Here multiple Saccharomyces cerevisiae GCR assays and query mutations were crossed into arrays of mutants to identify progeny with increased GCR rates. One hundred eighty two GIS genes were identified that supp...

The integration of building information modelling (BIM) and geographic information system (GIS) in construction management is a new and fast developing trend in recent years, from research to industrial practice. BIM has advantages on rich geometric and semantic information through the building life cycle, while GIS is a broad field covering geovisualization-based decision making and geospatial...

This paper describes an approach to reconstruct the complete history of a 3-d scene over time from imagery. The proposed approach avoids rebuilding 3-d models of the scene at each time instant. Instead, the approach employs an initial 3-d model which is continuously updated with changes in the environment to form a full 4-d representation. This updating scheme is enabled by a novel algorithm th...
