Open and Distance Education in Australia, Europe and the Americas : National Perspectives in a Digital Age
This book describes the history, structure and institutions of open and distance education in six countries: Australia, Brazil, Canada, Germany, the UK and the US. It discusses how open and distance education is evolving in a digital age to reflect the needs and circumstances of national higher education systems in these countries, and explores the similarities and differences between the ways in which they are organized and structured. It is the first book to make such comparisons and draw conclusions about the nature of open and distance education in the context of various national higher education systems. In a digital era with growing use of online education as well as open and distance education.
Ontologies for Agents : Theory and Experiences
On the other hand, ontologies have established themselves as a powerful tool to enable kno- edge sharing, and a growing number of applications have bene?ted from the use of ontologies as a means to achieve semantic interoperability among heterogeneous, distributed systems. In principle ontologies and agents are a match made in heaven, that has failed to happen. What makes a simple piece of software an agent is its ability to communicate in a ”social” environment, to make autonomous decisions, and to be proactive on behalf of its user. Communication ultimately depends on und- standing the goals, preferences, and constraints posed by the user. Autonomy is theabilitytoperformataskwithlittleornouserintervention,whileproactiveness involves acting autonomously with no need for user prompting. Communication, but also autonomy and proactiveness, depend on knowledge. The ability to c- municate depends on understanding the syntax (terms and structure) and the semantics of a language. Ontologies provide the terms used to describe a domain and the semantics associated with them. In addition, ontologies are often comp- mented by some logical rules that constrain the meaning assigned to the terms. These constraints are represented by inference rules that can be used by agents to perform the reasoning on which autonomy and proactiveness are based.
One Hundred Years of Chemical Warfare : Research, Deployment, Consequences
On April 22, 1915, the German military released 150 tons of chlorine gas at Ypres, Belgium. Carried by a long-awaited wind, the chlorine cloud passed within a few minutes through the British and French trenches, leaving behind at least 1,000 dead and 4,000 injured. This chemical attack, which amounted to the first use of a weapon of mass destruction, marks a turning point in world history. The preparation as well as the execution of the gas attack was orchestrated by Fritz Haber, the director of the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry in Berlin-Dahlem. During World War I, Haber transformed his research institute into a center for the development of chemical weapons (and of the means of protection against them).
Ondansetron Patches
The objective of this study was to develop the matrix of transdermal drug delivery system (TDDS) of ondansetron hydrochloride (ODH), in which ondansetron is the first serotonin subtype 3 receptor antagonist indicated for the treatment and/or prophylaxis of postoperative, chemotherapy or radiotherapy induced emesis. It has been proven efficient and safe to treat such symptoms, by using in vitro drug release study and evaluate the effect of eucalyptus oil and different percentage of carbopol 940. The result of drug release decreased by increasing the percentage of carbopol 940 which achieved the purpose of the study by prolonging the release of the ondansetron . The patch provides a means to reduce the side effects associated with its oral therapy, avoidence of the first-pass metabolism and minimize inconsistency in absorption across GIT. Various types of transdermal patches are used to incorporate the active ingredients into the circulatory system via skin.
Oncology : An Evidence-Based Approach

Further sections present fundamentals of supportive care of the cancer patient, the management of oncologic emergencies and acute toxicities of therapy, as well as care of metastatic disease and the terminally-ill patient. Breaking new ground, the textbook features thoughtful, in-depth sections on cancer prevention and control, cancer surviorship, the economics of cancer care, and cancer informatics. Cancer imaging is covered with an organ system-based approach, with an additional chapter on the especially intriguing potential of PET. Furthermore, a comprehensive section on translational basic science reviews the fundamentals of molecular biology, the cell cycle and signal transduction, carcinogenesis, cancer genetics, the biology of invations and metastasis, and tumor immunology.
On Bypass : Advanced Perfusion Techniques
With the introduction of cardiac surgery more than five decades ago and the use of the heart-lung machine for open heart surgical procedures granting the surgeon unlimited time in which to operate inside the heart, a complex task has been given to the Perfusionist. With a pairing of a perfusionist and a surgeon for each chapter, On Bypass: Advanced Perfusion Techniques is an essential collection of techniques and protocols to aid in the difficult and immediate decision making in the operating room. Among the topics covered in this comprehensive text are pediatric perfusion techniques for complex congenital, separation from cardiopumonary bypass, blood flow during cardiopumonary bypass, and minimally invasive perfusion techniques. Also covered is ultrafiltration in cardiac surgery, echocardiography and cardiopulmonary bypass, and advances in long-term pulmonary support.
OMDoc : An Open Markup Format for Mathematical Documents [version 1.2]
Computers arechanging the way wethink. Of course,nearly all desk-workers have access to computers and use them to email their colleagues, search the Web for information and prepare documents. But I’m not referring to that. I mean that people have begun to think about what they do in compu- tional terms and to exploit the power of computers to do things that would previously have been unimaginable. This observation is especially true of mathematicians.
Olfactory knows the truth
Olfaction, the sense of smell detects and discriminate odors as well as social cues which influence our innate responses. The olfactory system in human beings is found to be weak as compared to other animals; however, it seems to be very precise. It can detect and discriminate millions of chemical moieties (odorants) even in minuscule quantities. The sense of smell is greatly underappreciated, despite the fact that it monitors the intake of airborne agents into the human respiratory system and determine to a large degree the flavor and palatability of foods and beverage. In addition to enhancing quality of life, this primary sensory system warns of spoiled foods, leaking natural gas, polluted air and smoke, and mediates basic elements of communication (e.g., mother-infant interaction). It is now apparent that smell dysfunction is among the first clinical signs of such neurodegenerative diseases as Alzheimer’s disease and sporadic Parkinson’s disease.

Official Statistics 4.0 : Verified Facts for People in the 21st Century
Explores official statistics and their social function in modern societies. Digitisation and globalisation are creating completely new opportunities and risks, a context in which facts (can) play an enormously important part if they are produced with a quality that makes them credible and purpose-specific. In order for this to actually happen, official statistics must continue to actively pursue the modernisation of their working methods.
Office Andrology
The investigation and management of male infertility can be a formidable diagnostic challenge to family physicians, urologists, and reproductive specialists alike. In Office Andrology, noted clinical physicians and scientists have joined forces to create a comprehensive resource guide to current diagnostic and treatment options for a broad spectrum of clinical issues relevant to male infertility disorders. Topics covered range from basic sperm biology and male reproductive endocrinology, to immunology, specialized sperm testing, and the genetic background to male infertility. Although emphasis is on the investigation, diagnostic testing, and management of the infertile male, controversial medical and surgical treatment options are also fully discussed. For the reproductive specialist, the text thoughtfully reviews such timely issues as gender selection, human immunodeficiency virus-discordance couples, and posthumous reproduction. Other topics of interest include laboratory accreditation, vasectomy reversal, ethical and legal considerations of donor insemination, optimizing success in a donor insemination program, and strategic therapies for ejaculatory disorders and erectile dysfunction in infertile men.
Ocular Traumatology
All aspects of ophthalmic trauma from the lid to the optic nerve of both mechanical and nonmechanical trauma are covered in this unique book. The focus is on practical issues and incorporates cutting-edge approaches, such as temporary keratosprosthesis, artificial iris diaphragm, and prophylactic retinectomy. This book explains and answers not simply the “when”, the “what”, and the “how”, but also the “why” questions. The information is based on epidemiologic and clinical data from evaluation to management.
Observing the Sun with Coronado™ Telescopes
At around the turn of the millennium, the introduction of the Coronado range of solar telescopes and filters heralded the ‘coming of age’ of amateur solar astronomy. Before then, solar astronomy was mostly white-light only. Hydrogen-alpha systems were expensive and difficult to use, but today even the budget-priced Coronado PST (Personal Solar Telescope) provides a band pass of one Angstrom and is thermally stable. That means that today’s amateur solar observers can see – and image – sunspots, flares, prominences, plage, filaments, and active regions of the Sun, all in amazing detail.
Observation of the Earth System from Space
A special highlight is the - termination of seasonal gravity variations caused by changes in continental water masses. For GOCE, to be launched in 2006, new gravity field analysis methods are under development and integrated into the ESA processing s- tem. 200,000 GPS radio occultation pro?les, observed by CHAMP, have been processed on an operational basis. They represent new and excellent inf- mation on atmospheric refractivity, temperature and water vapor. These new developments require geodetic space techniques (such as VLBI, SLR, LLR, GPS) to be combined and synchronized as if being one global instrument.
