Explore the unspoiled, remote located Surin Islands on a truly island adventure trip from Phuket by SeaStar Andaman without the usual high amounts of visitors. Get the privilege to snorkel around the pristine reef sites off the Surin Islands following the guidelines of the Green Fins initiative to protect the coral reefs after the massive bleaching in 2010. Learn about the nomadic sea culture of the Moken and spot turtles, reef sharks, eagle rays and with a little bit of luck impressive whale sharks, manta rays and dolphins which often patrol the islands.

Role of Anti-Oxidants in Composite Resin Bonding Following Bleaching ab 39.99 EURO Form concentration and application time of anti-oxidants in composite bonding following bleaching
Bleaching and composite restorations, as combined treatment, form a conservative approach for treatment of discolored, mal-shaped and mal-positioned teeth. However, bleaching affects immediate composite resin restoration bonding to teeth. Use of anti-oxidants has been recommended to address this problem. Lately, alpha tocopherol (vitamin E) has been suggested as an anti-oxidant for this purpose. Literature wise, hardly any studies and information are available on its form, concentration, and application time and their relationship to its clinical effectiveness. Therefore, this book, based on a study, provides information on the above aspect. This book should assist Dental students and research scholars and esthetic and restorative dentistry specialists and general dentists in gaining knowledge and deriving the benefits to optimize their desired outcome in their field of application pertaining to tooth bleaching, use of anti-oxidants and composite restorations.
The effect of different concentrations of hydrogel of sodium ascorbate on bond strength of bleached enamel for varying periods of time and the mode of failure was evaluated.Seventy enamel surfaces were obtained from 35 human extracted premolars. Specimens were divided into four groups: no bleaching (control), bleaching with carbamide peroxide gel, bleaching and application of 10% / 20% sodium ascorbate hydrogel for 30, 60, 120 min. Surfaces were bonded with a total etch bonding system and composite resin. Specimens were tested for shear bond strength. Mode of failure was determined by stereomicroscope. Data were analyzed using a two-way analysis of variance, and Scheffe's post hoc test. Sodium ascorbate hydrogel application following bleaching increased the resin-enamel bond strength and was directly proportional to its duration of application. However, there was no difference in bond strength with an increase in the concentration of sodium ascorbate hydrogel. Immediate bonding of composite resin to bleached enamel is possible after treatment with antioxidant sodium ascorbate hydrogel.
This book features in-depth and thorough coverage of Minimum Impact Mill Technologies which can meet the environmental challenges of the pulp and paper industry and also discusses Mills and Fiberlines that encompass "State-of-the-Art" technology and management practices.The minimum impact mill does not mean "zero effluent", nor is it exclusive to one bleaching concept. It is a much bigger concept which means that significant progress must be made in the following areas: Water Management, Internal Chemical Management, Energy Management, Control and Discharge of Non-Process Elements and Removal of Hazardous Pollutants. At the moment, there is no bleached kraft pulp mill operating with zero effluent.With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the pulp and paper industry. Sustainable pulp and paper manufacturing requires a holistic view of the manufacturing process.During the last decade, there have been revolutionary technical developments in pulping, bleaching and chemical recovery technology. These developments have made it possible to further reduce loads in effluents and airborne emissions. Thus, there has been a strong progress towards minimum impact mills in the pulp and paper industry. The minimum-impact mill is a holistic manufacturing concept that encompasses environmental management systems, compliance with environmental laws and regulations and manufacturing technologies.
A self-contained treatment of the latest fluorescence applications in biotechnology and the life sciences This book focuses specifically on the present applications of fluorescence in molecular and cellular dynamics, biological/medical imaging, proteomics, genomics, and flow cytometry. It raises awareness of the latest scientific approaches and technologies that may help resolve problems relevant for the industry and the community in areas such as public health, food safety, and environmental monitoring. Following an introductory chapter on the basics of fluorescence, the book covers: labeling of cells with fluorescent dyes; genetically encoded fluorescent proteins; nanoparticle fluorescence probes; quantitative analysis of fluorescent images; spectral imaging and unmixing; correlation of light with electron microscopy; fluorescence resonance energy transfer and applications; monitoring molecular dynamics in live cells using fluorescence photo-bleaching; time-resolved fluorescence in microscopy; fluorescence correlation spectroscopy; flow cytometry; fluorescence in diagnostic imaging; fluorescence in clinical diagnoses; immunochemical detection of analytes by using fluorescence; membrane organization; and probing the kinetics of ion pumps via voltage-sensitive fluorescent dyes. With its multidisciplinary approach and excellent balance of research and diagnostic topics, this book is an essential resource for postgraduate students and a broad range of scientists and researchers in biology, physics, chemistry, biotechnology, bioengineering, and medicine.
