In this paper, we present the design and implementation of DrIveSCOVER, a recommender system for places and events in case of an in-car use, where the driving conditions such as weather and local traffic are taken into account. We integrate multiple data sources using semantic technologies and we devise recommending functions that are presented in a web-based application. Data is organized acco...

This paper develops a theoretical framework which allows for both domestic and external factors in the determination of interest rates. We argue that if capital controls are imposed, or if the risk premium is a function of disequilibria in the money market, domestic factors should also play a role. We assess empirically the role of both domestic monetary conditions and open economy factors in t...

Although homeostatic mechanisms remain of utmost importance, rhythmic changes are present also. The main ones have a period of 24 h (circadian) or about 2-3 h (ultradian). Circadian rhythms are derived from a body clock, found in the base of the brain, and from the pattern of our sleep-wake cycle, including activity and meal times. These rhythms promote the regular changes between an active wak...

Monitoring and managing performance in the workplace is nowadays an important aspect, in a time in which methodologies like Agile push individual and team limits further. Current performance monitoring approaches are either intrusive or based on productivity measures and are thus often dreaded by workers. Moreover, these approaches do not take into account the importance and role of the numerou...

External ventricular drainage (EVD) is frequently used in neurosurgery to drain cerebrospinal fluid in patients with raised intracranial pressure. We performed a retrospective single center study in order to evaluate the incidence of EVD-related infections and to identify underlying risk factors. 246 EVDs were placed in 218 patients over a 30-month period. EVD was continued in median for 7 days...

We examined the evolution of expression of duplicate genes in Arabidopsis thaliana, by analyzing 512 data sets of gene expression microarrays and 2022 recent duplicate gene pairs. Expression divergence between gene duplicates is significantly greater in response to environmental stress than to developmental processes. A slow rate of expression divergence during development might offer dosage-de...

By variation of nutritional and other external conditions we have determined the factors that limit the multiplication rate and the culture growth in Tetrahymena thermophila. The enriched synthetic medium of Kidder & Dewey (1951), a culture temperature of 29 degrees C, and aeration by agitation were chosen as reference conditions. The final cell density is increased by and proportional to the a...

Microbial biotechnology is expected to change production methods, the products themselves and the structure of the industries in the new economies. Hopefully, countries in the Middle-East, Latin America, Asia and Africa have already recognized the importance of microbial biotechnology's promise. In this sense, the importance of externalities which might affect the success or failure of these co...

PURPOSE To determine the maternal and fetal outcomes of successful external cephalic version (ECV) as well as factors predicting vaginal birth. METHODS The ECV data over a period of three years at Universiti Kebangsaan Malaysia Medical Centre (UKMMC) between 1 September 2008 and 30 September 2010 was reviewed. Sixty-seven patients who had successful ECV were studied and reviewed for maternal,...
