Tunnel (4.75 m diameter) was excavated with an open TBM within quartzitic mica-schist, under a cover not greater than 800 m. | Lang-8 is foreign language learning service Tunnel (4.75 m diameter) was excavated with an open TBM within quartzitic mica-schist, under a cover not greater than 800 m. Tunnel excavation became more complicated gradually as we approach the fault zone (after about 1800 m ).Near chainage 2359 m TBM is blocked, because of exceeding the plasticization threshold and the movement of a block of 25 cm from the right pier. Stability conditions have become so difficult to require continuous placement of liner plates. La galleria (4.75 m di diametro) è stata scavata con un TBM aperta all’interno di micascisti quarzitici, sotto una copertura non maggiore di 800 m. Le condizioni di stabilità sono diventate talmente difficili da richiedere l’installazione di pannelli metallici.

Social investing – the emperor's new clothes? First of all, I commend anyone engaging or seeking to achieve a better society for all. That said, I have a number questions about social finance and social investing. I dislike waste, inefficiency, lack of transparency and situations when people and businesses pretend to be something they are not. There is much debate taking place around philanthropy, charity and giving; especially around social finance but what makes me uncomfortable is the notion of making returns from society's ills. There is a return for social investment but I do not think it should be financial. Supporters of these new innovations talk about recycling and leveraging your money so that it can go even further – which sounds excellent in theory. The mere fact that social bonds and contracts are complicated means they require consultants, experts and money men – and they're expensive. It will take time to iron out issues such as liquidity, caps on returns, no track record, measurement metrics. 1) Do business well.
Ready for Transport November 13, 2013 Ready for Transport The massive tunnel boring machine (TBM) that will be used in the construction of the $ 1.4 billion Evergreen Line project is on its way by rail and truck from the manufacturer in Ontario to a site in Port Moody, B.C. The TBM will bore a two-kilometre tunnel that will run west of Barnet Highway in Port Moody to south of Kemsley Avenue in Coquitlam. Due to its size and weight, the machine is being shipped in pieces and assembled at a launch site. The TBM is 85 metres long and 10 metres in diameter. The first piece of the machine, called the cutter head (left), weighs 130 tonnes. Tunnel construction is expected to start in February 2014. ..d Moving an average of eight metres a day, it will take about a year to build the tunnel. Print | Comment

Second TBM starts work on São Paulo’s Line 5 – Lilac Photo: Diogo Moreira/ Governo do Estado de São Paulo. Two of the tunnel boring machines being used in the construction of São Paulo Metro’s Line 5 are now in operation – the first time in Brazil’s history that two TBMs have been in use simultaneously to build a single line. The new TBM, named Tatuzão, joins Megatatuzão which was lowered into a portal in the city’s Campo Belo district in July. Tatuzão, which will dig at a rate of 15 metres a day, is one of three TBMs which will construct a 4.8-kilometre extension of Line 5 – Lilac from Campo Belo to Chácara Klabin station in Vila Mariana. Once complete, the R $7.5 billion extension will more than double the current 8.5 kilometre route, adding 11.5 kilometre of additional track and 11 new stations. The 1.9 kilometre tunnel between the current terminus station, Largo Treze, and the first of the new stations, Adolfo Pinheiro, is expected to be completed by January next year.
Hillside Strangler The Hillside Strangler is the media epithet for two men, Kenneth Bianchi and Angelo Buono, who were convicted of kidnapping, raping, torturing, and killing girls and women ranging in age from 12 to 28 years old during a four-month period from late 1977 to early 1978. They committed their crimes in the hills above Los Angeles, California. Murders The first victim of the Hillside Strangler was a Hollywood prostitute, Yolanda Washington, whose body was found near the Forest Lawn Cemetery on October 18, 1977. On November 1, 1977, police were called to a La Crescenta neighborhood, north east of downtown Los Angeles, where the body of a teenage girl was found naked, face up on a parkway in a residential area. Five days later, on November 6, 1977, the nude body of another woman was discovered near the Chevy Chase Country Club. Two girls, Dolores Cepeda, 12, and Sonja Johnson, 14, boarded a school bus and headed home on November 13, 1977. Trial Veronica Compton See also
Incubators, Accelerators and Impact Investors, oh my! We need more incubators and accelerators, or so I am told, because start-ups, small businesses and social enterprises are not investment ready. Lots of would-be Fund Managers descry this lack of investment-readiness as a key reason for long investment periods and poor returns. On the flip side, well-meaning venture philanthropists have heard this cry and hope that by funding incubators and accelerators, deal flow will improve and more investments will be made. Although I am a huge fan of collaborative effort, this strikes me as a good fix for the wrong problem. The wrong problem is “how do we make these companies attractive to venture capital (VC) investors?”. . . . . 1. 2. 3. 4. 5. Lauren Burnhill, @LaurenOPV Like this: Like Loading...
