Ce livre traite de la pr paration et des diff rentes propri t s des nanocomposites biod gradables base d' thyl ne-ac tate de vinyle (EVA), d'amidon thermoplastique (TPS) et d'argile. Le m lange a t pr par diff rentes compositions et leurs propri t s ont t tudi es la composition optimale du m lange. Le poly thyl ne greff l'anhydride mal ique (MAPE) a t utilis pour am liorer les propri t s m caniques du m lange optimis . Na+MMT, l'argile trait e Cloisite30B et Cloisite20A ont t ajout s la matrice du m lange optimis et leurs propri t s m caniques, thermiques, morphologiques, m caniques dynamiques, d'absorption d'eau et de biod gradabilit ont t tudi es. Les r sultats ont montr que la biod gradabilit et les propri t s m caniques taient am lior es par l'ajout d'amidon et de nano-argiles. Nous esp rons que le pr sent travail stimulera la recherche et les progr s dans ce domaine fascinant et qu'il aboutira une utilisation commerciale g n ralis e du m lange EVA/TPS.

This volume contains the main lectures and poster contributions presented at the 7th International Symposium on the Plant Hormone Ethylene held in Pisa (Italy), June 18-22, 2006. This international scientific event was organized by the University of Padova and the Scuola Superiore Sant’Anna of Pisa and took place on the premises of the Scuola Superiore Sant’Anna. We would like to thank the Ministry of Agriculture and Forestry, the Ministry of University and Scientific Research of Italy, the University of Padova and the Scuola Superiore Sant’Anna of Pisa for partially funding this symposium. Appreciation is also extended to a number of local insti- tions that generously contributed to the success of this important event. We are indebted to the members of the scientific committee. A special appreciation goes to the local organizing committee headed by Prof. Giovanni Serra. Finally, we gratefully acknowledge Dr. Alessandro Botton for handling all the editorial aspects concerning the publication of this volume. The Editorial Board

Validation of Ethylene Oxide Sterilization

Validation of Ethylene Oxide Sterilization

This is a laboratory study to develop protocols for the validation of ethylene oxide sterilization. This study includes methodologies for physical, microbiological, and residual chemical qualification using a validated gas chromatography technique (GC/FID). The present study allowed for the optimization of the sterilization process, ensuring safety, robustness, and increased process efficiency by reducing the residual aeration time from 48 hours to 6 hours. The innovative methodologies of this research incorporated the use of physical sensors and chemical integrators, as well as the use of sterility tests and endotoxin assays in comparison to the biological monitoring technology of the rapid bioindicator test. Quality control analyses, qualifications, and validation of all stages of sterilization ensured the effectiveness of the process, in accordance with the criteria of the Brazilian Health Regulatory Agency, allowing for productivity gains and increased system performance.

Biochemical and Physiological Aspects of Ethylene Production in Lower and Higher Plants

Biochemical and Physiological Aspects of Ethylene Production in Lower and Higher Plants

With the demonstration of the "triple response" in plants by Neljubow at the turn of the century, ethylene has been identified as a substance specifically affecting plant growth. Yet it took a few more decades to show that ethylene is a naturally occurring product of plants having all the characteristics of a phytohormone. Ever since much effort has been devoted to a wide variety of physiological and biochemical problems relevant to ethylene. A first meeting was organized in Israel in 1984 to bring together many people active in this rapidly expanding field of experimental research. It is the aim of the present symposium to provide once more a forum at which researchers might expose and comment progress in their work over the last few years. Speakers were invi ted and their contri buti ons ordered ina number of sessions, each of which was centered on a particular topiC. Much of the benefit came from ensuing discussion sessions which were conducted with much competence and expertise by Anderson, Ben-Arie, Goren, Morgan and Osborne. All of these colleagues are recognized leaders in ethylene research today and the organizers owe a very special gratitude to them for their substantial contribution to the programme. It is well to remember the friendly atmosphere, so essential to the success of the whole meeting and so much enjoyed by every partiCipant. Prompt publi ca tion of the papers was made possi ble by the camera-ready procedure offered by the publisher.

Biology and Biotechnology of the Plant Hormone Ethylene

Biology and Biotechnology of the Plant Hormone Ethylene

Springer
1997

Ethylene is a simple gaseous plant hormone produced by higher plants, bacteria and fungi. Thanks to new tools that have become available in biochemistry and molecular genetics, parts of the ethylene biosynthesis, perception and signal transduction reactions have been elucidated. This knowledge has been applied to enhance the quality of a number of agronomically important crops. In Biology and Biotechnology of the Plant Hormone Ethylene, leading figures in the field provide surveys of the current state of ethylene biosynthesis and action, perception and signal transduction pathways, senescence, biotechnological control, and the involvement of ethylene in pathogenesis and stress. Audience: Indispensable to all academic, industrial and agricultural researchers as well as undergraduates and graduates in plant biology, biochemistry, genetics, molecular biology and food science.

The inflorescence of the monoecious maize plant is unique among the Gramineae in the sharp separation of the male and female structures. The male tassel at the terminus of the plant most often sheds pollen before the visual appearance of the receptive silks of th the female ear at a lateral bud, normally at the 10 leaf [I]. Earlier studies examined the ontogeny of the growing tissues beginning with the embryo in the kernel through to the obvious protuberances of the growing point as the kernel germinates. The differentiated developing soon-to-become tassel and the lateral bulges that develop into the ears on the lateral buds become apparent very early in the germinating kernel [2, 3, 46]. A certain number of cells are destined for tassel and ear development [8]. As the plant develops, there is a phase transition [\3, 16] from the vegetative lateral buds to the reproductive lateral buds. This change in phase has been ascribed to genotypic control as evidenced in the differences among different genotypes in the initiation of the reproductive [I]. The genetic control of tassel and ear initiation has been gleaned from anatomical observations. Lejeune and Bernier [I2] found that maize plants terminate the initiation of additional axillary meristems at the time of tassel initiation. This would indicate that the top-most ear shoot is initiated on the same day as the initiation of tassel development and this event signals the end of the undifferentiated growing point.
