Principles of Foundation Engineering
Braja M. Das' Fifth Edition of PRINCIPLES OF FOUNDATION ENGINEERING maintains the careful balance of current research and practical field applications that has made it the leading text in foundation engineering courses. Featuring a wealth of worked-out examples and figures that help students with theory and problem-solving skills, the book introduces civil engineering students to the fundamental concepts and application of foundation analysis design. Throughout, Das emphasizes the judgment needed to properly apply the theories and analysis to the evaluation of soils and foundation design as well as the need for field experience.86% (15)
MV Kyles - tied up at Braehead
KYLES is a rare survivor, a representative of Clyde shipbuilding dating from the 1870s - a period of expansion for both the shipbuilding on the west coast of Scotland and for Glasgow as a whole. She was launched on Tuesday 12 March 1872 at the Merksworth yard of John Fullarton & Co of Paisley. Her engines were supplied and fitted by Wm. King & Co of the Dock Engine Works, Glasgow. Her first register entry in Lloyds lists her as a 90A1 flush deck lighter with an iron hull and a pitch pine deck. She was fitted with a single pitch pine mast and derrick and carried a single suit of sails. She was registered in Glasgow and her first owner was Stuart Manford of 24 Oswald Street in the city. KYLES was a basic cargo coaster, typical of the many built by the smaller yards on the Clyde. Manford worked her as a tender for the firth of Clyde fishing fleet. The fishing fleet tenders collected the catch from the fishing boats and transported the fish to railheads on the coast allowing the fleet itself to remain profitably at the fishing grounds. In 1881 Manford sold KYLES to William Vietch, a chemical manufacturer resident in Creiff in Perthshire. Only a few years later he sold her on to another owner in Newcastle-upon-Tyne. Records show that KYLES was bought and sold several times over the next fifteen years, although her port of registry remained Glasgow. It was not until 1900 that this was altered and she was registered at Hull. Only a year later, she was purchased by a grocer and corn dealer from Pontypridd in Wales, who was the first in a succession of owners in the South Wales area. From 1919 to 1921 she was working in the East Kent and Thames waters, before once again being bought by a Welsh owner - this time a Cardiff tug master. During all these years she had been used for the purpose she had been built for and carried heavy and general cargoes on short coastal voyages. The first major change in KYLES’s structure was made in 1921 when she was converted to work as a sand dredger in the Bristol Channel, lifting sand and gravel for the building industries. By the outbreak of the Second World War, KYLES seems to have been taken out of service and de-registered. She was surveyed in 1942 while laid up on the Glamorganshire canal, and was found to be in poor condition. She was acquired by a salvage contractor and sold on to Ivor P Langford, a ship owner and ship repairer based at Sharpness near Gloucester. Langford bought her in 1944 and had her repaired and structurally altered, removing the dredging equipment to return her to a modernised cargo form. The alterations were substantial and included enlarging the forecastle and poop and adding improved and expanded crew quarters. KYLES was reregistered at Gloucester. Members of the Langford family recollect that he had a particular affection for KYLES. She was the only vessel in his fleet that he did not rename, possibly because he respected the fact that she had managed to keep her original name for such a long time. Langford worked her as a steamer in the Bristol Channel for a number of years, then in 1953 had her converted from steam to a diesel engine. In 1960 she was converted structurally once again to function as a sludge tanker for dumping industrial waste in the Bristol Channel. Eventually she was downgraded even from this lowly work and became a storage hulk for the waste, which was taken out for dumping by another, more modern, tanker. The Langford family had by this time retained a long association with KYLES and were keen to ensure that a vessel of such age and varied history should be preserved. There were moves to establish a maritime museum at Gloucester but in the meantime the Langfords accepted an offer from Captain Peter M Herbert of Bude, who had himself a long career in the coasting trade. KYLES became a celebrated vessel in the Bude area. During the early 1980s the West of Scotland Boat Museum Association, precursor of the Scottish Maritime Museum, was established and came to the notice of Peter Herbert, who offered to sell KYLES to the group. On 8 November 1984 the Scottish Maritime Museum became the 24th registered owner of the vessel and KYLES was reregistered in Glasgow, 112 years after her first appearance in the records. In 1996 funding for a full restoration of the vessel became available. It was decided to recognise KYLES’ long and varied career in the restoration and that the most suitable appearance to restore her to was to take her back to her 1953 refit when she was changed from steam to diesel power. Work began in 1997 to strip out the sludge tanks, reinstate the original hatch and hatch cover and replicate the mast and derrick. Her wheelhouse had been removed in the 1970s and this was replicated from old photographs of the vessel. Work was completed in 1999 and after sea trials KYLES made a well publicised arrival back to her birthplace on the river Clyde where she forms part of the displays at Clydebuilt, the Scottish MHellhole, Pendleton County, West Virginia 1
Here is a report from Peter Youngbaer NSS 16161 WNS Liaison: Update from Hellhole: On Saturday, a joint West Virginia Department of Natural Resources, U.S. Fish and Wildlife, and NSS project did a photographic documentation and bat population survey trip into Hellhole Cave, West Virginia. This project came together very quickly over the past 3-4 weeks, once flying bats were observed outside the cave. While awaiting laboratory confirmation of WNS in a couple of Little Brown bats, organization moved forward on several fronts. I was asked to organize cave/bat photographers from around the country and get official NSS Project status, while logistics were organized in terms of equipment, travel, and permits and waivers. Fifteen people on three different crews went in to document three separate areas of the cave. Each crew had guides from the Germany Valley Karst Survey, a biologist, and photographic crews. The jobs were to photograph everything, count and observe bats, replace temperature and humidity data loggers, and remove an appropriate number of bat carcasses, if any. We were able to connect with and include a National Geographic photographer and assistant, who are working on a WNS story for a future issue. Hellhole is only one of the sites they have visited. For context, Hellhole is West Virginia's largest bat hibernaculum. The last survey (2007) showed over 112,000 bats. The majority are Little Browns, but some 4-5% of the known Indiana bats live here, and over 6,000 Virginia Big Ears - about 45% of the entire known population on the planet. The last two species are federally listed as endangered. The bad news: upon arriving at the sinkhole entrance, plenty of bats were readily observed exiting the cave and flying outside. Many flew off into the distance to a certain death, given the absence of food supply this time of year. Others were seen landing and "wing-walking" on the snow. In the entrance room (a 160 foot drop into a huge bell chamber), bats were everywhere - flying, on the walls, and the floor littered with carcasses. Virtually all were Little Browns. From one 15 meter square sample area, a gallon-size Ziplock bag was filled with dead bats. The rest of the floor was the same. For context, the 2007 survey observed only one bat in the entrance room. At the different Little Brown roosting sites, WNS was in clear evidence, and carcasses found along the way. In the deepest recesses of LBB roosts, lesser amounts of the fungus were evident, implying that bats had moved to the entrance area, consistent with behaviors observed in northern sites. The Indiana clusters also showed WNS - ranging from a reported 12% to 50%. An observer who had NY sites to compare said it looked like what they had seen in year one of an infestation. For comparison, the data from the northeastern sites affected for several years has shown that the Indiana mortality numbers are in the 50% range, as compared with the Little Browns well into the 90% range. The good news: No evidence of WNS was seen in the Virginia Big Ears. This was extremely encouraging, as their roosts are located in places along the routes where the other infected species pass. Some pre-trip speculation had hoped that things might be different with this species. Why? 1. It's a different species; 2. they roost in very dry areas (70% humidity as confirmed by data loggers); 3. they roost in very cold areas - around 32 degrees F, including occasionally below (again temperature loggers at the sites have shown this consistently); 4. they rouse quickly, which may indicate they don't need to burn the sort of fat reserves other species do in order to amount an immune response. All of these things will need to studied and analyzed, of course, but, for now, the news is very good. Let's hope it stays that way. A caution: we've seen WNS progress very slowing in other how-humidity sites, but not be stopped, so we'll need to see that the VBE's continue to remain untouched over a few years. This is just one site, and one observation, but it's clearly a highly significant one. The work of compiling all the thousands of photographs taken, the comparison of the traditional clicker and cluster density methods of counting to the new photographic methods, and the analysis of the data logger data, will take a while, so a more complete report will come later. An NSS News article is planned for the future. A huge thanks to the cavers of the Germany Valley Karst Survey for not only safely and efficiently guiding the crews to the sites, but also for use of their field house for pre- and post-cave meetings. One last, but important note: Hellhole is owned by a limestone quarry, which electronically monitors the caver for any unauthorized intrusion. As a result, we know that no one has been in the cave since February, 2007. Thus, we know that WNS arrived here by bat to bat transmission, not via humans. Peter Youngbaer NSS 16161 WNS Liaison
