The Constructions of Deduction

Gallons = (capacity measure) United States liquid unit equal to 4 quarts or 3.785 liters A new   kind of concrete   from the UK building materials company Tarmac instantly soaks up gallons and gallons of H20–simultaneously preventing flood conditions while also conserving water by cycling it directly back into the ground. It’s called   Tarmac Top mix Permeable, and it’s a super-porous concrete pavement designed to remove storm and flood water from parking lots, driveways, side walks, and other surfaces. It was designed by Britain’s La Farge Tarmac, who call the idea part of a “sustainable urban drainage system.” Water enters the permeable concrete top layer, and then passes through pebbles beneath to become groundwater in the soil. In 60 seconds, it can drain 4,000 liters of water, or just over 1,000 gallons, according to a promotional   video   from the company. The company says that the concrete could be installed anywhere to miti...

Americans could one day soon cruise between two major cities in the western US on a mega-fast train at 150 mph, thanks to a   new agreement between a private US venture and a consortium led by China Railway Group . It’ll be called   XpressWest , and it’ll link the 230 miles separating Los Angeles and Las Vegas. The train will get you there in 80 minutes, versus a four-hour car ride. Construction’s set to kick off next September, and comes on the heels of four years of negotiations. It’s China’s first high-speed rail project in the US, and Bloomberg reports that $100 million in initial capital will get the project off the ground. (Though that’ll be just a teeny drop in the bucket—the project is   expected   to cost upwards to $7 billion). To date, only private sector funds have covered the bill, but the project’s applied for loans with the Federal Railroad Administration. In a   press release , XpressWest and China Railway International USA said: “The...

Def.:-   Points, crossing, turnouts, cross-overs and such related terms are the arrangements by which different routes either parallel or diverging are connected and afford the mean for trains to move from one route to another. These connections are not only useful for trains to move from one route to another but also help for marshalling and shunting work in station yards. Marshalling Yard: -   Yard in which wagons are sorted and new trains are formed are called “ Marshalling Yards ”. Station Yard :-   Yard is the system of tracks laid within prescribed limits for various purposes such as storing, sorting, dispatching of vehicles and making up trains. Movement of vehicles in yards is not authorized by a time-table. Necessary of Points and crossings & Its Functions:-  In case of road, the facilities for turning of vehicle from one path to another, do not require any special arrangement as the wheel have no flanges. The direction of movement...

In the 1980s cult classic,   National Lampoon's European Vacation , Clark Griswold drives into London, England with a beaming smile. Tucked into a yellow Austin Maxi hatchback, his wife and two children eagerly take in the sights and sounds of the new city. Then, without warning, Griswold endures a true American nightmare: he   enters a roundabout .  A roundabout in Shanghai, China Unable to get over into the left lane and exit, he helplessly circumnavigates the concrete orb for hours. Eventually, his repeated cries — “Hey look kids, there’s Big Ben! Parliament!” — grow increasingly more desperate, and he is driven to the point of mental instability. Unfortunately, this is telling of most Americans’ opinion of roundabouts. As beacons of unfamiliarity, the roughly 3,700 circular traffic intersections in the U.S. are feared, avoided, and even loathed, often without good reason. It seems that every time traffic engineers propose to build a new one, there is pro...
