Fatal falls from great height are a frequently encountered setting in forensic pathology. They present--by virtue of a calculable energy transmission to the body--an ideal model for the assessment of the effects of blunt trauma to a human body. As multislice computed tomography (MSCT) has proven not only to be invaluable in clinical examinations, but also to be a viable tool in post-mortem imaging, especially in the field of osseous injuries, we performed a MSCT scan on 20 victims of falls from great height. We hereby detected fractures and their distributions were compared with the impact energy. Our study suggests a marked increase of extensive damage to different body regions at about 20 kJ and more. The thorax was most often affected, regardless of the amount of impacting energy and the primary impact site. Cranial fracture frequency displayed a biphasic distribution with regard to the impacting energy; they were more frequent in energies of less than 10, and more than 20 kJ, but rarer in the intermediate energy group, namely that of 10-20 kJ.

This chapter will examine how transnational film making allows national and iconic stories to shift outside their imposed national boundaries, freeing them from “nation building” constraints and predetermined ideological motivations. Each interpretation creates one more dimension to the story’s complexity and hybridity assuring its continuance and relevance into the future. Each new film version, and in the case of iconic stories, each new transnational film version, breathes new energy and life into the stories and also stops monolithic ownership of them. What is also of interest in this chapter is the judgement cast upon each of the retelling and adaptations of these iconic stories. Every adaptation is weighed up and judged against a mythic ideal, and as such, each always falls short of imagined expectations. But in a paradoxical fashion, it is this failure to capture that provides the impetus for the story’s future retellings.

The clippings describe the City of the Falls and its attempts by its shareholders to sell lots to this newly developing city. The venture by shareholders W. Allan, James Buchanan, Thomas Clark, J.H. Dunn, Thomas Dixon, General Murray, James Robinson, Samuel Street and William Witla intended to favourably position their city as a destination for “affording an easy approach for the annual assemblage of the Fashionable, the Learned and the Great”. The venture failed due to the building of the Buffalo and Niagara Falls railway.

This collection contains 40 stereo cards of Niagara Falls and the Niagara River. Images include Niagara Falls in winter (the ice bridge); Prospect Point; the Whirlpool Rapids and the Whirlpool; the Upper River rapids; the Maid of the Mist; and Dixon crossing the Niagara River on a tightrope below the Great Cantilever Bridge. Twenty of the cards were published by Underwood & Underwood. The remaining cards are from various publishers including Keystone View Company, American Stereoscopic, Griffith & Griffith, H.C. White Company, E. & H.T. Anthony & Company, and Realistic Travels Publisher. George E. Curtis and Geo. Barker are listed as photographers on a few of the cards.

The description reads "(39) Tireless Niagara - Horseshoe Falls from above - U.S.A.". The reverse states "We are standing on the Canadian side of the river, looking S.E. across the enormous curve of the Horseshoe toward the Dufferin Islands on the Canadian side. 'This is close enough. The time will come undoubtedly when no man can reach this point, when the rocks on which we stand will break and crash into the gulf above which they hang. Table Rock one of the best known points about Niagara in the past, used to extend out over the river from the bank just behind us. It was originally very large but great masses, sometimes a hundred feet in length by fifty in width, have broken off at different periods, the last in 1883, until the whole rock is gone. Off to our left is the centre of the Horseshoe. It is easy to see that in that direction the water is going over in a solid mass, thousands of tons each second, to the river 150 feet below. While the amount of water passing over these rocks varies somewhat according to the height of the river. It has been estimated that the average amount is 12,000,000 cubic feet per minute, that is, about 375,000 tons...Since 1842 the whole contour of these falls has been worn away at the rate of about 2 1/10 ft. per year. In the centre of the Horseshoe where the bulk of the water passes, nearly five feet of rock are worn away each year. The falls have receded 100 feet within the memory of the men now living.' From Niagara Through the Stereoscope, with special 'keyed' maps, published by Underwood & Underwood"

This study examines the effect of the Great Moderation on the relationship between U.S. output growth and its volatility over the period 1947 to 2006. First, we consider the possible effects of structural change in the volatility process. In so doing, we employ GARCH-M and ARCH-M specifications of the process describing output growth rate and its volatility with and without a one-time structural break in volatility. Second, our data analyses and empirical results suggest no significant relationship between the output growth rate and its volatility, favoring the traditional wisdom of dichotomy in macroeconomics. Moreover, the evidence shows that the time-varying variance falls sharply or even disappears once we incorporate a one-time structural break in the unconditional variance of output starting 1982 or 1984. That is, the integrated GARCH effect proves spurious. Finally, a joint test of a trend change and a one-time shift in the volatility process finds that the one-time shift dominates.

At a longtime station near the "Grosse Meteor Bank" in the North Atlantic 41 subsequent hauls were made in April 1967 with the Helgoland larva net with changing bucket device. In addition 9 hauls were made during July 1967. The catches from the depth ranges of 900-700 m, 700-500 m, 500-300 m, 300-200 m, 200-100 m, and 100-0 m were collected in separate buckets during each catch series. Contamination, though possible on principle, does not seem to be of much consequence in appendicularia. After some comments on certain species caught it is shown that at this station in the open ocean the density of appendicularia not only varies with the season, but that clouds of plankton may pass by it within a few hours, in which the density may vary at a ratio of ten or more to one. In the composition of species as many as four species may in turn be the most abundant. For one species the composition as to size and stage of maturity may change in the same way. Regarding the depth distribution there are no species restricted to deeper layers. Below 100 m the number falls to about 1 % of the uppermost layer. Oikopkura longicauda, O. cophocerca, O.parva and Althoffia tumida as well as Fritillaria species are found between 900 and 100 m in comparatively higher numbers than Stegosoma magnum, Oikopleura albicans and O. intermedia. The Chaetognaths were collected in the depth of 900-0 m in vertical hauls with the Helgoland larva net with changing bucket device; buckets had been changed in the depth of 700, 500, 300, 200,1 00 m. In the course of the investigation it appeared that for Chaetognaths the sampling method with changing bucket device is insufficient. Many specimens remained in the net and entered the bucket at a higher level than that in which they had lived, mostly during flushing the net (sample 100-0 m); this means considerable contamination. In spite of this difficulty deep layers of higher abundance could be traced for Sagitta lyra and some other species. For some species large local variations in the number of specimens within a short time were found. Moreover notes have been made of foodorganisms, parasits and anatornic metamorphoses during maturing.
