KKH connects Kashgar, China to Islamabad, Pakistan, and is an approximately 3000 km long interlocking road and rail transportation hub that crosses the CPEC. The area around the CPEC is frequently disturbed by geological hazards, mainly landslides in northern Pakistan, which will severely damage ...
Known asa lumberjack saw, two-person crosscutsawshave a leading edge that leans back slightly and is sharpened at an angle to form a precise edge and tip. Each tooth acts like a knife to score the wood, allowing sawdust to fall out as the blade passes. They’re the right choice for ...

Interestingly in this feasibility study that section is shown as existing. No rail exists between Delta Junction and Valdez--about 270 miles over permafrost, tundra and at couple mountain passes, one of which, Thompson Pass, is about 2800 feet, less than ten miles from the port and gets and...
I knew Niagara Falls was in Buffalo…so when I had to select the flight from Las Vegas and did not know which airport to go, I typed in “Buffalo”, and the auto-complete function “told” me that I will land in Buffalo Airport. We arrived there and was looking forwards to the walk...
(LCA) was first carried out for a standard double-track rail-way line, considering the railway entirely in an embankment or in a cut section. Different construction and maintenance techniques of railway bodies and superstructures were analysed for each section. For a correct analysis of LCA, it...
Normal stresses along rock yielded-joint that runs beneath the tunnel opening at various in situ stress ratios K. Figure 13 depicts the shear stress along a rock yielded joint that passes beneath the tunnel opening at various in situ stress states. It can be shown that the direction of shea...
It is necessary to mention that in order to satisfy the lifecycle of the asphalt layer, fatigue damage and settlement are among the main aspects of the design criteria for this layer. Both of these aspects are related to the number of train passes. In this regard, Société nationale des ...
Particle Size Particle size distributions were measured using a Horiba LB-550 dynamic light scattering instrument (Horiba Scientific, Kyoto, Japan). The dispersant (water) refractive index was set at 1.333 and was temperature corrected for each sample via a temperature sensor that was placed in the...
The incident ray passes through different layers of tissues and is reflected by them. The ε and d also depends on the wavelength of light, while the c and d can be time varying in case of motion [10]: n Io = Ii·exp − ∑ j·cj(t)·dj(t) j=1 (1) According to Equation ...
