The normal forms deened in MNE96], OY87a], OY89], RK87] are investigated with respect to generalizing 4NF and BCNF, reducing redundant data values, and design exibility. In addition, we also examine their algorithms and the nested database schemes that they generate. Except in the case that if the given set of MVDs is not connict-free, then the normal form deened in MNE96] is inferior to the ot...

Many maturity models have been used to assess or rank e-government portals. In order to assess electronic services provided to the citizens, an appropriate e-government maturity model should be selected. This paper aims at comparing 25 e-government maturity models to find the similarities and differences between them and also to identify their weaknesses and strengths. Although the maturity mod...

Paracetamol suppositories in two different bases were given to children who had fever after operations. Plasma concentrations and the effect on temperature were compared. There was a significant correlation between peak plasma concentrations and maximum drop in temperature. A lipophilic base produced better results than a hydrophilic base.

Explanations of adult involvement in sex work typically adopt one of two approaches. One perspective highlights a variety of negative experiences in childhood and adolescence, including physical and sexual abuse, family instability, poverty, associations with "pimps" and other exploiters, homelessness, and drug use.

The use of contextual information is a vital ingredient in the successful postprocessing of edge information. Edge postprocessing is concerned with locating and labelling consistent edge-structures given confused or noisy response information. The available contextual information exists in the form of measurements provided by the gradient-vectors in pixel neighbourhoods and knowledge of accepta...

Embedding experimental data is a common first step in many forms of dynamical analysis. The choice of appropriate embedding parameters (dimension and lag) is crucial to the success of the subsequent analysis. We argue here that the optimal embedding of a time series cannot be determined by criteria based solely on the time series itself. Therefore we base our analysis on an examination of syste...

this article presents an overview of the recent Frequency dependent and Frequency independent antenna theory. An antenna is defined by Webster’s Dictionary as “a usually metallic device (as a rod or wire) for radiating (transmitting) or receiving radio waves or EM wave.” The IEEE Standard Definitions of Terms for Antennas (IEEE Std 145–1983) defines the antenna as “a means for radiating or rece...
