Torulaspora delbrueckii: aplicaciones tecnológicas y aislamiento de genes de respuesta a estrés.
2005
Durante los últimos años la producción de masas congeladas para bollería ha experimentado un notable incremento. La calidad de estos productos está lejos de la que se obtiene a partir de masas frescas Esto es debido a la sensibilidad al proceso de congelación y descongelación de S. cerevisiae y a la reducción de su capacidad fermentativa durante el almacenamiento. Si las masas congeladas son azucaradas el problema es todavía mayor. En la elaboración de masas dulces se utiliza hasta un 30% de azúcar provoca una fuerte reducción de la actividad de agua generando ambientes de alta presiones osmóticas. Como consecuencia de todo esto el tiempo de fermentación de estas masas se prolonga y el volu…
Filles et garçons à l'école, approches sociologiques et psycho-sociales. 2e partie : La construction scolaire des différences entre les sexes
1995
International audience; Après avoir examiné, dans une première partie, les différences de scolarisation entre garçons et filles et tenté de rapporter ces différences à des attitudes en grande partie générées dans la famille et l'environnement social, il est temps d'analyser plus précisément cette socialisation qui prend place dans le contexte scolaire, par laquelle l'école participe à la construction des différences entre les sexes. Dans la classe, où ils passent une grande partie de leur temps et se forgent progressivement une image d'eux-mêmes, les enfants reçoivent, au-delà des interactions strictement pédagogiques, une grande quantité d'informations sur les comportements adéquats pour l…

Original strain energy density functions for modeling of anisotropic soft biological tissue
2017
This thesis has focused on the construction of strain energy densities for describing the non-linear behavior of anisotropic materials such as biological soft tissues (ligaments, tendons, arterial walls, etc.) or fiber-reinforced rubbers. The densities we have proposed have been developed with the mathematical theory of invariant polynomials, particularly the Noether theorem and the Reynolds operator. Our work involved two types of anisotropic materials, the first with a single fiber family and the second with a four-fiber family. The concept of polyconvexity has also been studied because it is well known that it plays an important role for ensuring the existence of solutions. In the case o…

Contribution à la compréhension des causes des comportements socialement responsables : l'étude des contrats psychologiques au sein d'une entreprise …
2014
Stakeholders require companies to include in their management process social responsibility criteria such as health and safety and the fight against discrimination etc. Standards of CSR or sustainable development (ISO 26000, 14001, OHSAS 18001, 1000 AA ...) are many and reflect the issues and difficulties in its operationalization. NGO‟s criticisms reveal, among other things, the lack of commitment of employees who are at the very heart of the company's shares. This work is part of doctoral research determining causes of socially responsible behavior of employees. We discuss our research in terms of the Employment Relationship-Organization-and inscribe our work in the concept of psychologic…
The role of Private Equity-firms in the formation of strategic alliances
2014
This research analyses the role of Private Equity firms in the formation of strategic alliances within the field of the French Private Equity market. We start to provide evidence of its importance from new survey information, before offering an explanation of the organizational phenomenon. The study addresses the questions of how and why Private Equity firms act as relational intermediaries to help their portfolio companies form alliances. Both questions are investigated in the light of the Private Equity firms’ contribution to the value creation process that comes with alliance formation. Answers are provided by means of three jointly used theoretical frameworks: (1) mainstream theories (t…

Agroecological engineering
2015
Earth has recently entered the new era of the Anthropocene, during which the rise of human activities are impacting for the first time ecosystems and climate on the global scale. Since the 1960s the green revolution has improved food production in quantity using industrially-designed agriculture, which has led to global pollution by pesticides and losses of food quality, biodiversity and soil carbon. As a consequence there is a need to implement agroecological practices in order to produce food safely and in a sustainable way. This virtual issue presents principles and applications of agroecological engineering, exemplified in 19 selected review articles from the journal Agronomy for Sustai…
Handover management in heterogenous mobile and wireless networks
2015
Since 1990, networking and mobile technologies have made a phenomenal unprecedented progress. This progress has been experienced on multiple fronts in parallel; especially on the application level and the user's needs one. This rapid evolution of the technology imposed a need for the existence of heterogeneous environments where the coverage is ensured throughout the different available networks. The challenge with such architecture would be to provide the user with the ability to navigate through the different available networks in a transparent and seamless fashion. However, the navigation among different types of networks is commonly referred to as vertical Handover. The IEEE 802.21 stan…
