  • Microfabricated accelerometer sensors have been developed to measure acceleration in a variety of applications, including automobile airbag crash sensors and seismic activity monitors. For this thesis a three-dimensional accelerometer sensor has been created for measuring involuntary human hand motion. The sensor uses three single-axis accelerometers fabricated at the MIT Microsystems Technology Laboratory.

  • The Strategic Learning concept presented in this book owes a lot to the two great learning laboratories that have shaped my ideas. The first was my two decades as a CEO. These years infused in me a strong sense of pragmatism. Life in the trenches, I discovered, is always messy. So the most important question to ask about any business idea is simply, Does it work? In these pages, I’ve tried to capture some of the ideas that do work, so that my colleagues in business leadership may benefit from them....

  • What is Economics? Economics is not a natural science, i.e. it is not concerned with studying the physical world like chemistry, biology. Social sciences are connected with the study of people in society. It is not possible to conduct laboratory experiments, nor is it possible to fully unravel the process of human decisionmaking. “Economics is the study of how we the people engage ourselves in production, distribution and consumption of goods and services in a society.” Normative economics and Positive Economics: Normative economics refers to value judgments, e.g.

  • Therefore, ex vivo expansion of BMSCs is required to obtain a sufficient number of transplantable cells. Since BMSCs require several kinds of supportive factors for their growth, it is standard practice to use fetal bovine serum (FBS), while autologous human serum (HS) and pooled allogeneic HS have also been used. It has been suggested that FBS may not be favorable for clinical applications due to the possible risk of contamination (prions, viruses, zoonosis) or immunological reactions against xenogeneic serum antigens (Agata et al., 2009).

  • The growth of magnetic resonance imaging (MRI) as a tool for studying brain function, as opposed to its more traditional role as a tool for studying brain anatomy and pathology, has been quite remarkable over the past decade. This has been driven in large measure by an appreciation of the considerable potential for functional magnetic resonance imaging (fMRI) to increase our understanding of how the human brain works, both in the normal and diseased states.

  • The prominence of private health insurance has been buttressed by government interventions directed at PHI markets in several OECD health systems, although the effectiveness of policies aimed at increasing market size and fostering outcome quality has differed widely. Australia, Ireland, the Netherlands, Germany, Switzerland and the United States have promoted and maintained a large and viable private health insurance market because policy makers have concluded that mixed public-private coverage systems can better deliver desired health policy and social outcomes.

  • Those of us involved in the healthcare of women have seen a remarkable transformation in screening techniques for cervical cancer and its precursors since the mid 1990s.  The staid old Pap smear technique of scraping cells from the cervix with a wooden spatula and cotton-tipped applicator and smearing them onto a glass slide is a thing of the past in most practices. We now use plastic collection devices to transfer cells from the cervix into a preservative which is sent to the lab for liquidbased cytology and reflex human papillomavirus (HPV) testing.

  • The English poet, John Keats, explored this relationship when he asked: “Do we retreat from the reality of the outer world into ourselves at times, or do we retreat from the pressures of the outside world into the reality of our inner selves?” (Philipp, 2001a). In taking this question further, the doctor-poet, Dannie Abse, musing on it in 1993, noted that: “imaginative daydreaming is an escape from the precipitous pessimism of living or dealing with problems and the sphere of sorrows, and it is used to restore balance” (op.cit.).

  • Seismic – At the Weyburn Field, multi-component 3-D surface seismic time-lapse surveys were conducted at intervals of approximately 12 months, starting prior to the commencement of CO2 injection in 2000, and repeated in 2001 and 2002. The resultant time-lapse images (primarily seismic amplitude changes) acquired at Weyburn clearly map the spread of CO2 over time within the reservoir, fulfilling a key objective set at the outset of the project.

  • An additional element in the prevention of introduction and spread of disease is the use of vaccination. The manual does not cover this aspect but the importance of an appropriate vaccination strategy is acknowledged, and vaccination as a possible risk management measure should form part of the overall biosecurity assessment and strategy. The purpose of the manual is to establish a minimum set of biosecurity guidelines, applicable to all poultry producers (including ratites) from hatcheries to the point of delivery at the processor.

  • By the close of official activities, the project had already contributed notably towards increasing the productivity of livestock in the RCA countries, largely by increasing the production of milk and meat. This, in turn, enhanced the incomes of the participating farmers. In addition, due to the establishment of close coordination between this project, national projects and coordinated research programmes, several laboratories have received complementary assistance for upgrading their facilities and for consolidating their experimentation capabilities in the field.
