Biogeography, Time, and Place : Distributions, Barriers, and Islands
Biogeography considers the distribution of biological units over a wide range of scales. The units range from genotypes, populations and species to families and higher taxa. Processes can be local, such as the isolation on islands due to sea-level fluctuations, or large-scale tectonic processes that separates continents and creates oceans. In all processes time is an important factor and by combining data on recent patterns with paleontological data the understanding of the distribution of extant taxa can be improved. This volume focuses on speciation due to isolation in island-like settings, and the evolution of large-scale diversity as the result of origination, maintenance and extinction.
Bigel : An innovative drug delivery system
Bigel is a promising drug delivery system that modifies the pharmacotherapeutic characteristics of knowing active pharmaceutical ingredient (API).It is a mix between hydrogel and organogel (oleogel). The objective of the present work demonstrates the ability of bigel to overcome the disadvan- tages of both types of gels, including the limited ability to cross lipophilic barriers of the skin for hydrogels and the low patient compliance for organogels due to their stickiness and oily residues. Materials andmethods : Carbomer934, PolyvinylpyrrolidoneK 90 and Castor oil where mixed in a high shear mixer using diferent weight percentages of each. Hence,13 for mulations (BG1 to BG13) prepared by simplex mixture design modelis used to study the inuenceofafore- mentioned ingredients on appearance, dynamicviscosity, pH, stability, microscopicstructure of bigel and to understand the chemical interactions between bigel components, Fouriertrans- form infrared (FTIR) analysis will bereported.
Behavioral interventions for prevention and control of sexually transmitted diseases
Before AIDS, the role of behavioral interventions in preventing transmission of sexually transmitted diseases was acknowledged in text books and journals but rarely promoted effectively in public health practice. Informed by a comprehensive knowledge of behavioral theory, intervention methods, and affected populations, the authors of this important book examine the central role of behavioral interventions in combating STDs. The book addresses the complexities and social contexts of human behaviors which spread STDs, the cultural barriers to STD education (ranging from conservative mores to "stay out of my bedroom" libertarianism), and the sociopolitical nuances surrounding treatment.
Barriers and Biases in Computer-Mediated Knowledge Communication : And How They May Be Overcome
This books deals with computer-mediated cooperation and communication scenarios in teaching and learning situations, leisure activities (e.g. laypersons looking for expert information on the internet), and net-based communication at work. Such scenarios will become increasingly important. But the successful use of such computer-mediated settings is not trivial. Cooperative learning and work itself requires special skills and strategies. And the technical settings with sometimes restricted, sometimes new possibilities for communication add problems on top of the cooperation itself. What are the barriers in computer-mediated communication for cooperative learning and work? Which are the most relevant biases in computer-mediated information processing? Based on empirical research the contributors from psychology, education and computer sciences offer different perspectives on the nature and causes of such barriers.
Assessment of syrian physicians’ knowledge and management of dental trauma – combined survey
Dental trauma (traumatic dental injury, TDI) encompasses injuries to teeth, periodontium, and surrounding tissues, with significant physical, psychological, and socioeconomic consequences. Despite its high prevalence, particularly among children, many physicians lack adequate training in TDI management. This cross-sectional survey assessed Syrian physicians’ knowledge, practices, and confidence in managing dental trauma, identifying gaps and barriers to optimal care.
Applied Hydrogeophysics
This book focuses on how hydrogeophysical methods can be applied to solve problems facing environmental engineers, geophysicists, agronomists, hydrologists, soil scientists and hydrogeologists. We present applications of hydrogeophysical methods to the understanding of hydrological processes and environmental problems dealing with the flow of water and the transport of solutes and contaminants. The majority of the book is organized as a series of process-driven chapters, each authored by leading experts. Areas covered include: infiltration and solute transport processes, biogeochemical functioning of soil-water systems, coastal groundwater interactions, cold region hydrology, engineered barriers and landfill processes. In addition, the book offers insight into the development of new data fusion methodologies, of value to many hydrogeophysical investigations, and provides an account how the rapidly developing self-potential technique can give valuable information about water fluxes and hydrochemical states within the subsurface.
Acceptance and Usage of Technology through the Digital User Experience
Sheds light on the challenges and solutions for companies when dealing with the online consumer on social media and in the era of Web 4.0. It investigates the digital transformation in terms of customer experience, customer empowerment, resistance, influencer marketing, and trust. The volume shows how consumers perceive, react and behave towards brands’ digital marketing strategies in addition to the barriers, constraints, advantages and modes of action of online consumers.
