Strengthening of steel-reinforced concrete structural elements by externally bonded FRP sheets and evaluation of their load carrying capacity

2014

Abstract The paper proposes a preliminary design tool for reinforced concrete (RC) elements strengthened by fiber-reinforced-polymer (FRP) sheets to be used in civil engineering applications and in particular in medical buildings. The design strategy is based on limit analysis theory and utilizes a numerical procedure which provides a direct method to determine peak load, failure mode and critical zones of the structural elements of interest.

Steel and composite tied-arch bridges: a conceptual approach to structural design

2021

The behaviour of tied-arch bridges with composite decks (bowstring bridges) is overly sensitive to the different choices made by the designer in the first phases of the conceptual approach, mainly in the design of the arch and the deck. The geometry of the arch shape, the design of the arch–tie joint and the construction sequence can significantly modify the global behaviour in terms of stress state and deformed configuration. After a general discussion on the different parameters affecting the behaviour of bowstring bridges with steel–concrete composite decks, the consequences of choices made in the conceptual design phases are discussed, analysing the effects of each choice on the global…

Strengthening of steel-reinforced concrete structural elements by externally bonded FRP sheets and evaluation of their load carrying capacity to face…

2014

The paper has proposed a limit analysis procedure for a preliminary design of RC elements strengthened by externally bonded FRP sheets. The procedure, based on a multi-yield-criteria limit analysis approach, has led to a reliable prediction of peak loads and failure modes of the analyzed elements (slabs) by simultaneously considering the limit state of the constituent materials, so resulting very useful in many applications of engineering interest. The attention has been focused on hospital applications in which increment of service loads or realization of openings can weaken some structural elements that have been strengthened by FRP sheets.

Secondary impairment of pancreatic function as a cause of severe malabsorption in intestinal giardiasis: A case report

1997

We report the case of a 54-year-old male patient hospitalized for diarrhea and weight loss (8 kg over the previous three months). At admission, we observed pale oral and conjunctival mucosa and peripheral edema of the lower limbs. Stool frequency was 8-10 per day. Laboratory data were as follows: hemoglobin, 11 g/dL; total proteins, 4.3 g/dL; albumin, 2 g/dL; pseudocholinesterase, 1248 U/L; triglycerides, 54 mg/dL; serum cholesterol, 102 mg/dL; calcium, 7.9 mg/dL. Fecal fat was 8.2 g/24 hr. Fecal chymotrypsin (FCT) was 2.3 U/g. A duodenal probe was performed after administration of intravenous secretin and cerulein stimulation, and a contemporaneous mucosal biopsy was taken at the ligament …

¿Es real el riesgo de osteoporosis y riesgo de fracturas con el uso crónico de inhibidores de la bomba de protones?

2011

Proton pump inhibitors (PPI) are one of the most widely used groups of drugs and their potential toxicity is periodically reviewed, emphasizing aspects originally considered secondary. The present review analyzes the physiological and pharmacological bases and the scarce clinical evidence for a potential association between the continued administration of PPI and the development of osteoporosis and bone fractures. Both disorders are clearly related to calcium homeostasis and are highly important in elderly patients due to their poor general prognosis and disabling consequences.

Vitamin A (Retinol) und Retinolbindendes-Protein (RBP) im Serum bei Maldigestion, Malabsorption und Lebercirrhose

1974

Bei Normalpersonen und Patienten mit Malabsorption, Maldigestion und Lebercirrhose wurden vor und nach oraler Belastung mit 600 000 E Vitamin-A-palmitat bzw. wasserloslichem Vitamin A im Serum der Spiegel des Vitamin A (Retinol), des Retinol-bindenden Proteins (RBP) und Praealbumin bestimmt. In der Kontrolle steigt das Retinol nach Belastung signifikant an und erreicht nach 5 Std sein Maximum. Das RBP liegt im Mittel bei 42,25 mg/L, der Praealbuminspiegel bei 400 mg/L. Patienten mit Malabsorption und Lebercirrhose zeigen vor und nach Belastung mit Vitamin-A-palmitat einen gegenuber der Kontrolle verminderten Retinolspiegel. In der Gruppe der Maldigestion ist der Nuchternspiegel des Retinols…

Fruktose – Freund oder Feind?

2016

Die Aufnahme von Fruktose ist in vielen industrialisierten Landern weltweit in den letzten Jahrzehnten stark angestiegen. Dies resultiert u. a. aus einer zunehmenden Verwendung des reinen Monosaccharids oder des sog. „High Fructose Corn Syrup“ (HFCS, Maissirup oder auch Fruktose-Glukose-Sirup) als Susungsmittel. Neben Problemen fur Patienten mit einer angeborenen oder erworbenen Fruktosemalabsorption sowie der seltenen, genetisch bedingten hereditaren Fruktoseintoleranz, wird die vermehrte industrielle Verwendung und die damit einhergehende vermehrte Aufnahme von Fruktose uber die Nahrung als ein Risikofaktor in der Entstehung von Ubergewicht und damit assoziierten metabolischen Erkrankunge…

Tessuti sociali e spinte co-creative in politiche e fenomeni di resilienza urbana

2014

A fronte dei fattori di crisi rilevati dalle scienze economiche la questione dei futuri assetti spaziali delle città ed in particolare di quelle di livello metropolitano non sembra essere così decisiva come è apparso, ad esempio, alla Commissione Europea, a partire dalla programmazione di Agenda 2000 e soprattutto con la nuova programmazione 2014-2020 che consente alle città metropolitane di darsi una dotazione di smartness mediante risorse finanziarie pubbliche significative, l'enfasi delle politiche di investimenti pubblici concentrati sulle città si fonda su un supposto ruolo guida che non aggancia i reali fattori della loro crescita prima ancora che di uno sviluppo durevole. Nel periodo…
