The construction of the 57 km Mont d’Ambin Tunnel (also called Mont Cenis) between France and Italy started in 2016 but is facing now some questioning from the new italian government and the project could be delayed.
Frozen and cracked pump components are the chief suspect here, but another culprit could be running the pump without the water flowing, or ignoring other problems that cause the pressure washer to run incorrectly.
They both decided to stay, but they’re struggling more than most. They have a six-year-old daughter who has a congenital heart condition, and she’s had to be airlifted to a hospital in St. Louis four times. Pratt and workers in the plant raised money for Bennett and his wife, to tide them over while they sat at their daughter’s side. “It’s like a family here,” Bennett told me. “Chris has done things no one else would’ve done.” But Bennett has lost patience with Trump. “He doesn’t care to help us,” he told me. “At first, maybe he didn’t realize the tariffs would affect me and companies like this. But by now he knows exactly what he’s doing. I don’t know why I should continue to vote for him.”
"Ball milling and subsequent annealing is a simple method for the production of CNTs. Although it is well-established that mechanical attrition of this type can lead to fully nanoporous microstructures, it was not until a few years ago that CNTs of carbon and boron nitride were produced from these powders by thermal annealing. Essentially the method consists of placing graphite powder (99.8% purity) into a stainless steel container along with four hardened steel balls. The container is purged, and argon is introduced. The milling is carried out at room temperature for up to 150 hours. Following milling, the powder is annealed under a nitrogen (or argon) gas flow at temperatures of 1400°C for six hours. The mechanism of this process is not known, but it is thought that the ball milling process forms nanotube nuclei, and the annealing process activates nanotube growth. Research has shown that this method produces more MWNTs and few SWNTs."
Nobody told that this is the chain that rubs against the frame? And rear plates are subjected to friction therefore necessarily it heats!
I have read a few good stuff here. Certainly worth bookmarking for revisiting. I wonder how much attempt you set to make one of these magnificent informative site.
With its access to this legacy, TSC is finding new techniques to successfully apply Rutan’s basic manufacturing processes of hand layup, vacuum bag and out-of-autoclave (OOA) cure, while advancing its own methods for its specific spacecraft challenges. Alec Subero, TSC’s chief engineer for the next two spaceship models, SS2-003 and SS2-004, interprets TSC’s own paradigm: “What’s unique, what allows us to actually meet our space tourism goal, is that we use the processes in a different way. We have fine-tuned procedures based on the legacy from our predecessor technology that allow us to build the spaceships by less costly and faster methods, that allow us to be more nimble in our approach to changes, compared to a larger company that might be slower and more reluctant to react. For example, our combination of adhesives and OOA prepreg processing opens up flexibility in cure cycles, allowing us to make design changes quickly while minimizing disruption in the assembly flow of the spaceship.
Intelligent manufacturing cell Throughout the last decade, it became clear that we have an increased problem finding skilled workers. Automation is the answer to that. Attracting huge attention on the Salvagnini stand was the FlexCell, a solution designed to increase the capabilities of workshops organised in cells, by combining a panel bender and a press-brake. The Salvagnini OPS-FlexCell software optimises the production processes according to the bends to be made.
@Seven_tech: I share your frustration, but that’s not actually a useful test. You could put a bunch of people in a room and dose them intermittently with x-rays that will cumulatively kill them (later), and they couldn’t tell. Not being able to detect something that will kill you isn’t a good test for whether or not something will kill you, given that our bodies have a quite limited range of onboard sensors for EM. 
“Representation and inclusion in fashion were a priority for me before I had the language to express it. It always confused me that the industry didn’t look like the world I lived in. While I was a contributing fashion editor at Mirabella and New York Magazine in the ’90s, I pushed for and encouraged the use of models of all colors in our shoots (which was often met with blank faces). Today, as an actor and activist, I advocate for equality and representation in everything I do. I push up against unspoken cultural biases and norms at every opportunity. And as a designer, my blackness, my shape, my age inspired me to create a collection that was accessible to everyone.”—Tracee Ellis Ross, actor-designer-activist
The 42.6m/140-ft-long wing span on WK2 is built with two single-piece carbon fiber composite spars that run nearly the full length of the wing. Built in the manner of a conventional wing, the spars and ribs are installed into the sandwich structure for the lower wing. After various lines and control systems are also installed, the lower wing is closed off with the sandwich structure for the upper wing. A similar approach is used for building the boom tails for WK2 and SS2, “which are basically a pair of vertical wings,” Subero says.
Spaceships SS2-003 and SS2-004 are now in fabrication and assembly at TSC Mojave, following SS2 and exploiting lessons learned in its design and manufacture.
