OBJECTIVE: The objective of this study was to assess the contribution of [(18)F]fluoro-2-deoxy-D-glucose positron emission tomography ((18)FDG PET) imaging in the management of cervical cancer. METHODS: Fully corrected whole-body PET was performed in 60 patients (pts) with proven cervical cancer. In pretreatment staging, 22 pts underwent PET in addition to routine protocol including International Federation of Obstetrics and Gynecology (FIGO) staging and pelvic magnetic resonance imaging (MRI). Eighteen of them had pelvic lymphadenectomy. After treatment, PET was performed in 38 pts routinely followed up by clinical and radiological examinations. Results of PET and routine protocols were compared to final diagnoses, including histological findings in 31 pts and clinical outcomes in the other cases. Median follow-up time was 12 +/- 7.3 months. RESULTS: In all but 2 patients (FIGO stage IA), both PET and MRI detected the primary tumor. In 6 pts, MRI alone noted loco-regional tumor spread but PET localized 9 unsuspected extrapelvic nodal sites (6 para-aortic, 2 mediastinal, and 1 supra-clavicular). However, PET missed 8 microscopic pelvic nodal metastases. In 18% of the patients, PET staging significantly influenced the treatment choices. In follow-up, PET accurately diagnosed a recurrent disease in 13 pts with falsely negative or equivocal conventional imaging (CI). Ten patients with a negative PET were still in complete remission after a minimal follow-up time of 12 months. Overall, the agreement of PET with final diagnosis was significantly better than that of routine protocol (P < 0.05). CONCLUSIONS: Whole-body (18)FDG PET appears useful in the management of cervical cancer, in particular for staging extrapelvic metastases or optimally detecting a recurrence. MRI is better indicated for evaluating the loco-regional status of the disease. [less ▲]

Abstract : Poles of competitiveness were launched in Walloon region as a policy for innovation support. This policy aims to reinforce cooperation and partnering between industry and research universities in the region: critical mass, excellence, international size should be reached through the construction of large cooperative projects. Thes new dynamics were in line with the earlier ones which were developed as separate branches of research policy for universities and firms. The governance of the poles, largely controlled by the firms representatives, promoted the development of new forms of interactions between the institutional segments of the Triple Helix of innovation: state – industry – university. Universities stepped quickly in the poles dynamics and took advantage of the opportunity to reinforce their presence in the regional economic framework. Administration was not associated to the launch of the government-defined process and encountered difficulties stepping in the process and entering into these new modes of governance, more supportive than normative. The innovation model at the basis of the policy initiative sets a strong systemic stance to the dynamics of knowledge production but fails to deliver enough reflexivity to go beyond the narrow instrumental rationality of innovation.

We introduce in this thesis two entanglement detection criteria, the Schrödinger-Robertson partial transpose inequality, which can be implemented experimentally in a variety of systems and generalized N-qubit concurrences, which can be used to evaluate multipartite entanglement in N-qubit mixed states. Then, we investigate ways to experimentally produce entanglement by giving a theoretical model which successfully describes the dipole blockade effect. We study its possible applications in systems of two and three two-level atoms as well as its relations with the EITeffect in systems of two three-level atoms. Finally, we show the possibility of two-photon processes in a system of two two-level atoms embedded in a cavity by using perturbation theory and a full master equation approach. We unveil interesting features of blockade and transparency in such cavity QED systems. [less ▲]

The objective of this master’s thesis is to contribute to two main aspects of experimental tests on the behaviour of load-bearing masonry subjected to earthquake action carried out within the European research project SERIES. The first part explains the general context and presents the exploitation of results of the first phase of SERIES project TA5. This first phase investigates the response of four simple unreinforced clay masonry walls, two of them including acoustic insulation devices (SonicStrip). This phase has a double objective. On one hand, the tests aim at a better understanding of the seismic behaviour of single wall in dynamic conditions. On the other hand, the comparison between walls having a same global geometry, but with and without acoustic insulation devices allows the assessment of the consequences of the presence of that type of device on the seismic behaviour. The second part describes the design of specimens and the preliminary assessment of the structural behaviour of the second phase of the SERIES project TA5. The design is focusing on the investigation of the behaviour of T- and L-shaped walls, and in particular on the role of the parts of the structural elements perpendicular to the earthquake direction, and on the characterization of the frame behaviour in such masonry structures. The structural assessment is carried out according to Eurocodes 6 and 8 and considers different loading situations that can be found in daily practice. Some preliminary information on the experimental results of the second phase of the SERIES project TA5 are finally given." [less ▲]

The aim of this work was to create a complete conservation process of pomegranate seeds (Punica granatum L.). This process is essentially based on osmotic dehydration (OD), which was associated to freezing and air-drying process. Several parameters were studied to optimize the process such as osmotic solution (sucrose, glucose, and sucrose/glucose and date juice with sucrose added), temperature (30, 40, and 50°C) and state of the fruit (fresh and frozen). All these conditions were linked to seed proprieties (texture, structure, and colour). The study of osmotic dehydration parameters (water loss (WL), solids gain (SG) and weight reduction (WR)) showed that most significant changes of mass transfer took place during the first 20 min of dewatering using frozen seeds, independently of temperature and sugar type. During this period, seeds water loss was estimated at 46% in sucrose, 41% in sucrose/glucose mix, 39% in date juice, and 37% in glucose. Mass transfer was slower starting from fresh fruit but led to a higher rate of WL at the end of the process. This fact can be explained by scanning electron microscopy, which showed damage of seed cell structure after freezing. This has practical consequences in terms of the modification of seeds texture. The same process also revealed a modification of seed texture and cell structure after osmotic dehydration. Using a sucrose solution and a temperature of 50°C favoured the best mass transfer. The determination of different water fractions of seed by differential scanning calorimetry (DSC) showed that the % of frozen water decreased 3.5 times contrary the % of unfreezable water that increased 2.5 times. This favours a better seeds conservation. During osmotic dehydration, there was a non negligible leaching of natural solutes from seeds into the solution, which might have an important impact on the sensorial and nutritional value of seeds. Using only osmotic dehydration could not maintain the stability of seeds during conservation. In fact, after the osmotic process, water activity of seeds was found to be higher than 0.9, allowing to the development of microorganisms and some undesirable reactions. As a consequence, a drying of the pomegranate seeds (during four hours) was investigated at three different temperatures (40, 50, and 60 °C) with air flow rate of 2 ms-1. Prior to the drying process, seeds were osmodehydrated in a sucrose solution (55°Brix) during 20 min at 50°C. The drying kinetics and the effects of OD and air-drying temperature on antioxidant capacity, total phenolic, colour, and texture were determined. This work is a contribution to the study of physico-chemical properties of pomegranate seeds (Punica granatum L.) during freezing, osmotic dehydration and drying. After the global process, the pomegranate seed characteristics lead to new industrial developments. [less ▲]
