Digital libraries offer substantial volumes of declarative knowledge to the information society. This paper explores the extent to which current and future digital libraries, also known as ubiquitous knowledge environments, can be made sufficiently usable, accessible and smart to support an inclusive information society and the aspiration of universal access. Using a range of converging methods...

The prognosis for renal metastatic carcinoma is poor: in fact only a small portion of patients have metastases surgically treatable for their number and sizes with often a multiorgan involvement. We present a case in whit a solitary liver metastasis was incidentaly detected 17 years after nephrectomy for renal clear cell carcinoma. during a staging computed tomography performed for colonic canc...

Preeclampsia affects between 4 to 8% of all human pregnancies. It compromised both mothers and offspring beyond perinatal period. This is the first o two papers related whit this phenomenon and shows the available evidence about the effect of preeclampsia over the preeclamptic offspring from cohort studies. It is devoted to develop all facts related with respiratory distress syndrome, sepsis, n...

Airborne Laser Terrain Mapping is a proven technology for topographical surveys with accuracies equivalent to traditional land surveys. It is characterized by an automatic data capture and direct digital data processing. Since about 10 years Airborne Laser Terrain Mapping is an economical alternative to survey large and unaccessible areas, whit a short survey to product realisation time and wit...

Today, the inverters used in telecommunic-ation sector are controlled by PWM (Palse Width Modulation ) in this control technical the need of wide range of entrance and exit fılters makes the inverters highly costed. In order to get rid of these problems the fuzzy logic controlled inverters are suggested in this study the fuzzy logic control of inverters used in telecommunication is described an...

In this paper, we prove that every multiplier M (i.e. every bounded operator commuting whit the shift operator S) on a large class of Banach spaces of sequences on Z is associated to a function essentially bounded by ‖M‖ on spec(S). This function is holomorphic on ◦ spec(S), if ◦ spec(S) 6= ∅. Moreover, we give a simple description of spec(S). We also obtain similar results for Toeplitz operato...
