Le Corbusier e la fotografia

Abstract

Il rapporto fra architetti e fotografia è un tema scarsamente affrontato. Il volume, inoltre, costituisce una ricerca innovativa anche per il suo ampio raggio: non si limita a indagare l'uso da parte di Le Corbusier di fotografie, ma approfondisce i caratteri del modo di vedere dell'architetto svizzero. Vengono quindi colti: il significato delle fotografie di viaggio e di opere architettoniche (anche in confronto al disegno); i rapporti con i fotografi professionisti; le relazioni con la cultura fotografica contemporanea e con l'immagine cinematografica; i modi di impiego della fotografia come mezzo dimostrativo della propria opera o come elemento di qualificazione dello spazio architettonico.

Using Artificial Skin Devices as Skin Replacements: Insights into Superficial Treatment

“…This also fulfills the criteria of mechanical biocompatibility, allowing better integration between device and body. [41,42] Biological agents also present a threat in the form of infections and the skin is able to prevent this through biochemical defenses. This becomes even more important with implants as wet, implanted devices can be prone to biofouling and corrosion.…”

Poly‐(pentaerythritol adipate)‐co‐(poly ethylene glycol) Elastomers for the Sustained Release of Paclitaxel

“…The elution rate was 1 mL/min (DMF) and poly-styrene standards were used for the molecular weight calibration curve. 1 H-NMR spectra were obtained with a Bruker Avance II, 300 MHZ spectrometer using DMSO-d 6 or CDCl 3 containing 5% DMSO. The spectra were referenced to residual solvent signals (2.53 and 7.28 ppm for DMSO-d 6 or CDCl 3 respectively).…”

“…Nowadays it is widely accepted that for successful biomedical application, bio-elastomers should match the mechanical properties of the host tissue, among various other stringent requirements. 1 Moreover, biodegradable elastomers are widely recognized as interesting alternatives to traditional poly-(lacticco-glycolic acid) (PLGA) and related thermoplastics, such as poly-(glycolic acid) (PGA) and poly-(lactic acid) (PLA), as they can support the mechanical properties of the host tissue, but without causing irritation in the implantation site. [2][3][4] Among the various bio-degradable elastomers that have been reported recently, 5 most of the attention have been centered on polyurethanes, [6][7][8] poly-(polyol alkanoates), 9 including poly-(polyol adipate)s, 10,11 poly-(polyol sebacate)s, [12][13][14][15] such as poly-(glycerol-sebacate) and poly-(diol citrate)s. [16][17][18][19][20][21][22] All these materials showed good potential for their application in biomedical devices and implants.…”

Fracture behaviour of single crystal silicon microstructures

“…In fact, the constitutive behaviour of micromachined SCSi has been characterized in a number of micromechanical tests aiming at determining its elastic constants [1][2][3][4][5][6][7]. On the other hand, failure criteria and viable calculation procedures for the mechanical integrity analysis of SCSi microstructures are still missing, despite the availability of a certain amount of strength data [3,5,6,[8][9][10][11]. The definition of design criteria and practicable calculation procedures represents an essential step towards the realization of reliable and optimized SCSi microstructures.…”

“…The design criteria proposed in these works suffer of important limitations, since they only apply for specific notch geometry and loading conditions. An attempt for the derivation of a failure criterion of general validity is presented in [5]. There, experiments with microbeams subjected to tensile load are described and a failure criterion is formulated based on the comparison between the energy density in the notch near-tip region and the surface energy per unit area.…”
