Abstract We report results of numerical simulations a potential subaerial landslide on the coast Orcas Island and resultant tsunami waves in southern Strait Georgia near US/Canada border. A likely trigger is strong ground shaking during large earthquakes nearby Holocene active Skipjack fault zone. For worst-case scenario, we assume 0.17 $${\textrm{km}}^3$$ <mml:math xmlns:mml="http://www.w3.org...

In this paper the two-dimensional structure of protoplanetary disks around Herbig Ae/Be stars is studied. This is done by constructing a self-consistent model based on 2-D radiative transfer coupled to the equation of vertical hydrostatics. As a simplifying assumption a grey opacity is used. It is found that the disk can adopt four different structures, dependent on the surface density distribu...

With the development of the activities in deep sea, the application of the autonomous underwater vehicle (AUV) is very widespread and there is a prominent prospect. The development of an AUV includes many areas, such as vehicle (carrier/platform) design, architecture, motion control, intelligent planning and decision making, etc (Blidberg 1991; Xu et al., 2006). The researchers dedicate themsel...

Critical tissue ischaemia in scleroderma: a note of caution Vascular features dominate the clinical presentations of systemic sclerosis. Raynaud's phenomenon is the most typical presenting symptom. Renal involvement in early diffuse scleroderma and isolated pulmonary hypertension in late limited scleroderma are major causes of morbidity and mortality due exclusively to vascular change. A Raynau...

Bernardino Ramazzini was born in Carpi near Modina in Italy in 1633. He studied medicine in Parma and took his doctorate in 1659. After a year with Dr Rossi in Rome, he practised for some years in the province of Viterbo until a severe bout of malaria caused him to return to his home town. On recovering he married Francesca Righi. They had a son who died in infancy and two daughters. Carpi serv...

In this chapter, I provide argument and evidence that the scope of people’s ignorance is often invisible to them. This meta-ignorance (or ignorance of ignorance) arises because lack of expertise and knowledge often hides in the realm of the “unknown unknowns” or is disguised by erroneous beliefs and background knowledge that only appear to be sufficient to conclude a right answer. As empirical ...

After over 300 years of scrutiny, the subject of Galileo continues to be pursued with unabating intensity. Dava Sobel’s Galileo’s Daughter points to the popular interest in the man and his legacy. The Catholic Church, understandably interested in dispelling the notion that its censure of Galileo centuries ago is proof positive that religious faith and science as well as ecclesiastical authority...

We address the issue of dynamic modeling and control of the Bluefin Odyssey III class vehicle “Caribou,” operated by the MIT Sea Grant AUV Laboratory. Focus is on demonstrating a simple forward design procedure for the flight control system, which can be carried out quickly and routinely to maximize vehicle effectiveness. In many situations, the control loops are tuned heuristically in the fiel...

An understanding of fluid mechanical concepts is important for a variety of biological areas from biological oceanography to locomotion (swimming and flight) to cardiovascular physiology to diffusion within cells and across cell membranes. While graduate students in biomechanical areas are usually encouraged to take courses within engineering schools, the interests of undergraduate biology majo...
