Peritonitis after spontaneous rupture of pyonephrosis is a rare complication, usually diagnosed intraoperatively. We report the case of a 35 year old woman who was admited for an acute abdomen. Ultrasound showed features of acute peritonitis, with left pyonephrosis, confirmed by a CT-SCAN. Treatment consisted of laparotomy with nephrectomy and abdominal(More)
The microstructure of complexes between hydroxypropyl-cyclodextrins (HPCDs) (alpha, beta, and gamma) and a novel gemini surfactant has been investigated by small-angle neutron scattering (SANS). This nonionic hetero-gemini surfactant (denoted NIHG750) contains two hydrophobic groups and two hydrophilic groups. One is a methyl-capped polyoxyethylene chain(More)
Novel environmentally friendly gemini surfactants, each with two hydrophilic and two hydrophobic groups, have been synthesized and their physicochemical properties investigated. One of the hydrophilic groups is a methyl-capped polyoxyethylene chain with mol wt 350, 550, and 750 g/mol, respectively, and the other is a sulfate group; the hydrophobic part of(More)
The interaction between cyclodextrins, hydroxypropyl-beta-cyclodextrin (HPbetaCD), and hydroxypropyl-gamma-cyclodextrin (HPgammaCD) and a novel type of nonionic surfactant synthesized from a fatty acid has been investigated. The so-called nonionic heterogemini surfactant (NIHG750) contains two hydrophobic groups and two hydrophilic groups, composed of one(More)
Human expert behavior has always been a key element for the design and implementation of powerful Intelligent E-Learning Systems (IeLS). So far the modeling of this behavior has been very limited. The paper describes another model of expliciting human expert behavior. The model is composed of two related elements: the representation of the scientific(More)
