The municipality of Acajete is delimited to the north by Tlacolulan and Las Vigas de Ramírez to the east by Rafael Lucio, to the south by Tlalnelhuayocan and to the west by Perote.

The first one or two roof boards ( marked `` E '' in fig. 6 ) are slipped into place across the roof beams, from outside the shelter.

These boards are nailed to the roof beams by reaching up through the open space between the beams, from inside the shelter.

Concrete blocks are passed between the beams and put on the boards.

In medicine the frequencies are much higher, transducers and the sonar beams themselves are much smaller, and different scanning techniques may be used, but the principles involved are the same as in sonar.

Within the last courses of brick, bond beams are laid across the top of the bricks to provide a horizontal bearing plate for the roof to distribute the weight more evenly along the wall.

Taking into account the material from which the beams and walls are made, choosing the attachments may prove difficult.

A combination of the bricks and adobe mortar that are laid across the beams creates an even load-bearing pressure that can last for many years depending on attrition.

Once the beams are laid across the building, it is then time to begin the placing of adobe bricks to create the roof.

Beam bridges are horizontal beams supported at each end by substructure units and can be either simply supported when the beams only connect across a single span, or continuous when the beams are connected across two or more spans.

Cantilever bridges are built using cantilevers — horizontal beams supported on only one end.

For medium spans, trusses or box beams are usually most economical, while in some cases, the appearance of the bridge may be more important than its cost efficiency.

Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest.

Cathode rays are now usually called electron beams.

In order to reduce large shear reversals in the core walls in the basement, and at the top of the tower base level, the ground floor, basement levels 1 and 2 and the 5th and 6th floors, the floor slabs and beams are separated horizontally from the core walls.

Electron beams are used in welding, which allows energy densities up to across a narrow focus diameter of and usually does not require a filler material.

In radiation therapy, electron beams are generated by linear accelerators for treatment of superficial tumors.

For a brief period each year, the rays of the sun are warm enough to melt some of the snows piled a mile deep at the base of the headwalls, and then the pinnacles glisten in the daytime at high noon, and billions of gallons of water begin their slow seepage under the glaciers and across the rockstrewn hanging valleys on their long, meandering journey to the sea -- running east past the sky-carving massifs of Gurla Mandhata and Kemchenjunga, then turning south and curling down through the jungles of Assam, past the Khasi Hills, and into Bengal, past Sirinjani and Madaripur, until the hard water of the melting snows mingles with the soft drainage of fields and at length fans out to meld with the teeming salt depths of the Bay of Bengal.

I have just asked these questions in the Pentagon, in the White House, in offices of key scientists across the country and aboard the submarines that prowl for months underwater, with neat rows of green launch tubes which contain Polaris missiles and which are affectionately known as `` Sherwood Forest ''.

Furthermore, in certain respects, there are norms common to colleges and universities across the country.

All across the South there are signs that racial violence is finding less approval among whites who themselves would never take active part but might once have shown a tolerant attitude toward it.

Occasionally, you may come across one or two bumblebees in the cold season, when you are turning over sods in your garden, but you have to be a really keen observer to see them at all.

( C ) Af cuts across C and there are two ordinary intersections for every T in Af.

And there are now many millions of workers for whom the factory with the big parking lot, which can be reached by driving across or against the usual pattern of rush hour traffic and grille-route bus lines, is actually more convenient than the walk-to factory.

The downtown store continues to offer the great inducement of variety, both within its gates and across the street, where other department stores are immediately convenient for the shopper who wants to see what is available before making up her mind.

After paying tribute to the conductor and his white-clad youthful students, President Kennedy said, `` As an American I have the greatest possible pride in the work that is being done in dozens of schools stretching across the United States -- schools where devoted teachers are studying with interested young men and women and opening up the whole wide horizon of serious music ''.

That animals and humans are more altruistic towards close kin than to distant kin and non-kin has been confirmed in numerous studies across many different cultures.

Marco Polo's systematic observations of nature, anthropology, and geography are another example of studying human variation across space.

Austro-Asiatic languages have a disjunct distribution across India, Bangladesh and Southeast Asia, separated by regions where other languages are spoken.

Berber languages are spoken in Morocco, Algeria, Libya and across the rest of North Africa and the Sahara Desert by about 25 to 35 million people.

Depending on the thickness of the adobe bricks, the framework has been performed using a steel framing and a layering of a metal fencing or wiring over the framework to allow an even load as masses of adobe are spread across the metal fencing like cob and allowed to air dry accordingly.

Flowers across the Apiaceae are fairly uniform and are usually perfect ( hermaphroditic ) and actinomorphic, but some are andromonoecious, polygamomonoecious, or even dioecious ( as in Acronema ), with a distinct calyx and corolla, but the calyx if often highly reduced, to the point of being undetectable in many species, while the corolla can be white, yellow, pink or purple.

Individual axons are microscopic in diameter ( typically about 1μm across ), but may be up to several feet in length.

The main buildings at Pueblo Bonito, for example, are arranged according to this direction and probably served as central places for ceremonial journeys across the landscape.

There are differences in degrees of iconicity across sign types.

Maybe yes, maybe no, but you can observe everything from the roof of a barrack we are building ''.

The roof blocks are in two layers and are not mortared together.

The last roof boards are covered with blocks from outside the shelter.

When the roof blocks are all in place, the final rows of wall blocks are mortared into position.

If they are used, the walls and roof should be 10 inches thick to give the same protection as the 8-inch solid concrete blocks.

The roof timbers are precut and the panels standard so that the house can be completely enclosed in a matter of three or four days.

In a new house, generous roof overhangs are a logical and effective solution.

But now many of these same builders are finding they can cut their costs more by teaming up with a dealer who has volume enough to afford the most efficient specialized equipment to deliver everything just where it is needed -- drywall inside the house, siding along the sides, trusses on the walls, roofing on the roof, etc..

In the first courtyard there are some fine bas-reliefs and friezes, and in the second a series of delightful terraced roof gardens above an ivy-covered wall.

In many amphibians there are also vomerine teeth attached to a facial bone in the roof of the mouth.

Chalets often face south or downhill, are built of solid wood, with a steeply gabled roof to allow accumulated snow to slide off easily.

Forty columns support the roof, but no two are alike and the ornaments are exceptional in their decorations.

The two stadiums are roughly equidistant for Cubs fans living in north-suburban Chicago ; hence, fans in this region take advantage of Miller Park's larger seating and parking capacity, more modern amenities, and the certainty that the game will not be weather-delayed ( due to Miller Park's roof ) to attend Cubs games in Milwaukee in large numbers, enhancing the rivalry's intensity.

Its architectural features are meaningfully designed and include a high-pitched roof and skylight.

The exact origins of the name are unclear, but the fact that the roof looked like a corrugated iron shed roof played a part.
