Crystal structure of sinhalite MgAlBO4 under high pressure

2015

We report on high-pressure angle-dispersive X-ray diffraction data up to 27 GPa for natural MgAlBO4 sinhalite mineral and ab initio total energy calculations. The experimental bulk modulus of sinhalite is B-0 = 171(3) GPa with a first-pressure derivative of B-0' = 4.2(3). A comparison with other olivine-type compounds shows that the value for B0 is 27% larger than that of Mg2SiO4 forsterite and 29% smaller than that of Al2BeO4 chrysoberyl. These differences are interpreted, on the basis of our ab initio calculations, in terms of the relative incompressibility of Al-O bonds in AlO6 octahedra (with a calculated bulk modulus of 250(1) GPa) as compared to Mg-O bonds in MgO6 octahedra (with a ca…

The impact of the farming, abandonment and agricultural intensification on loss of water and soil. The example of the northern slopes of the Serra Gr…

Land abandonment throughout the twentieth century led to an intense landscape transformation in the mountain areas of the Iberian Peninsula. In some cases, and after 50 years of abandonment, agriculture returned with the development of commercial farms and the intensification of the agrarian activities. In the Easter Iberian Peninsula, following the abandonment of olive groves, vineyards and cereals during the 50's, has been in the past two decades the expansion of intensive citrus production on sloping terrain. Geomorphological transects and simulated rainfall experiments have quantified the impact of traditional rainfed cultivation of the 50's, abandonment, and the intensification of farm…

A rare case of acute idiopathic colocolic intussusception in an adult patient

2020

Abstract Adult intussusception is a rare condition that is frequently associated with malignancy and requires surgical approach. Symptoms are often non-specific and of subacute or chronic character. Therefore, computerized tomography (CT) scan is the most commonly used modality for identifying adult intussusception. A 51-year-old female presented with a 1-day history of increasing abdominal pain. Abdominal ultrasound and CT scan revealed intussusception. Intra-operatively, colocolic intussusception was present and laparoscopically reduced. A lead point was found neither intra-operatively nor in post-operative ileocolonoscopy and resection of involved bowel segments was not necessary.

Bacterial community response to changes in a tri-trophic cascade during a whole-lake fish manipulation

2015

Microbial communities play a key role in biogeochemical processes by degrading organic material and recycling nutrients, but can also be important food sources for upper trophic levels. Trophic cascades might modify microbial communities either directly via grazing or indirectly by inducing changes in other biotic or in abiotic factors (e.g., nutrients). We studied the effects of a tri-trophic cascade on microbial communities during a whole-lake manipulation in which European perch (Perca fluviatilis) were added to a naturally fishless lake divided experimentally into two basins. We measured environmental parameters (oxygen, temperature, and nutrients) and zooplankton biomass and studied th…

L’abside in facciata: soluzioni “antisismiche” del XVIII secolo in Sicilia

2015

Nel corso del Settecento vennero progettate e costruite in Sicilia facciate chiesastiche caratterizzate da conformazioni curvilinee. Forme convesse e concave, posizionate in corrispondenza del partito centrale della facciata rendono queste strutture assimilabili alle absidi. Scelte di natura estetica hanno inizialmente innescato fenomeni emulativi sulla base della ricezione dei modelli diffusi dalla seconda metà del Seicento in Sicilia dalle incisioni riproducenti le facciate inflesse prodotte dai maestri del Barocco romano. Finora l'interesse verso questi modelli è apparso lo schema interpretativo più pertinente per spiegare gli indirizzi progettuali dei maggiori artefici operanti nel Sett…
