Since they were first established, ex vivo models of lung reconditioning have been evaluated extensively. When rejected donor lungs are used, the great variability among the cases can hinder the progress of such studies. In order to avoid this problem, we developed a technique that consists of separating the lung block into right and left blocks and subsequently reconnecting those two blocks. T...

BACKGROUND To reduce the rate of recurrence of incisional hernia repair associated with open anatomic techniques, we present an experimental study, focusing on two different sutures, with the aim to apply clinically in a revised version of the Mayo technique. METHODS Thirteen biological tissue samples from adult pig central brawn and upper and lower fasciae were measured using two techniques ...

PURPOSE Choroidal neovascularization (CNV) is the end point of several ocular diseases that lead to blindness. The authors developed an imaging technique for visualizing and quantifying morphologic changes associated with experimental laser-induced CNV. METHODS CNV was induced using laser energy to disrupt Bruch's membrane. Rats were euthanatized immediately after laser injury and at 1, 2, 3,...

The surface properties of SOA generated from limonene and toluene using specific molecular probes: exploration of a new experimental technique B. Demirdjian and M. J. Rossi EPFL (Ecole Polytechnique Fédérale de Lausanne), LPAS (Laboratoire de Pollution Atmosphérique et Sol), CH-1015 Lausanne, Switzerland Present address: CRMC-N/CNRS, Campus de Luminy, Case 913, 13288 Marseille cedex 09, France ...

Landmines are an open problem in many countries of the world. They cause injuries and death and no technique proposed to date guarantees fast and 100% reliable detection alone. To this purpose, at the Humanitarian Demining Laboratory of “La Sapienza” University of Rome, several solutions are being studied. In this paper, numerical simulations of a prototype thermal detection system are reported...

An attempt to produce scoliosis in young baboons by excision of the heads of ribs failed in thirteen growing animals observed for up to a year after operation. Other investigators have failed to produce scoliosis in primates by similar and other techniques that had successfully produced scoliosis in quadruped animals. The possible reasons for this are discussed, especially in the light of clini...

Multidimensional scaling techniques (MDS) are a vibrant area of research with much development and advancement in last few decades. In this paper we focus on an interactive 2-dimensional interface for creating a similarity space for audio. Classical MDS techniques can place great demands upon participants overwhelming their sensory and cognitive abilities to make choices across such datasets us...

A two-staged technique for construction of experimental aneurysms in swine is described. The jugular vein is initially anastomosed to the carotid artery. Spontaneous hypertrophy of the vein is modeled by placing restraining sutures to create a fusiform aneurysm. Subsequent endovascular closure of this aneurysm leaves a sidewall aneurysm pouch. Staging allows maturation of the anastomosis, and t...

This paper presents a proposal of a test setup and methodology for testing the transfer length evolution through time of prestressing reinforcement in pretensioned prestressed concrete members, aimed at providing a basis for standardization. The proposed test method is based on the instantaneous and time-related analysis of the prestressing reinforcement force profile at only one end of a prete...

Mode group diversity multiplexing (MGDM) has been proposed as a means to create independent, transparent communication channels over a multimode fibre in short reach optical networks. In this paper we provide an experimental investigation of the MGDM technique focusing on the linearity of the fibre’s response and the temporal variations of the transmission matrix coefficients, which describe th...
