It is claimed that object oriented databases (OODBs) overcome many of the limitations of the relational model. However, the formal foundation of OODB concepts is still an open problem. Even worse, for relational databases a commonly accepted datamodel existed very early on whereas for OODBs the uniication of concepts is missing. The work reported in this paper contains the results of our rst in...

This research was concerned with the collection of empirical data necessary to estimate the effects of decision support tools on the performance of distributed groups. Data was collected in a controlled experimental environment that simulated a geographically-dispersed meeting through the use of videoconferencing and group communication support (GCSS) technology. Results of the use of a Group D...

Despite progress in recent years in understanding cloud processes and feedbacks in General Circulation Models (GCMs; Bony et al., 2006; Stephens 2005), knowledge is lacking about the physical mechanisms of cloud feedbacks and the causes of model-to-model variation in simulated cloud feedbacks. These issues are related to several factors: (1) the transient and spatial variability of clouds is ty...

Background As pregnancy accelerates glioma growth, therapeutic abortion has been recommended prior to tumor resection. Additionally, it has also been suggested that the extent of glioma resection is closely correlated with patient survival. Case presentation A 162-cm, 61.4-kg, 30-year-old, right-handed primigravida was referred to our institution at 21 weeks gestation to obtain a second opini...

Phyto-oestrogens are believed to have a range of beneficial effects on predominant Western diseases. A few studies on phyto-oestrogens in milk exist and show that the composition can be affected by feeding. Therefore, the aim was to study how feeding of lucerne and grass/clover silages (GCSs) affects the concentration of phyto-oestrogens in bovine milk. Sixteen Danish Holstein cows were assigne...

Background Patients with rheumatoid arthritis (RA) who have a difficult-to-treat condition (D2T RA) are often burden to both patients and rheumatologists. Objectives The aim of this study was determine the risk factors for failure treat in refractory conditions find them relevant prevention. Methods RA were treated under treat-to-target (T2T) strategy more than one year picked up. Their backgro...
