CALLANISH SCOTTISH STONEHENGE
The stones and arches of Stonehenge indicate the points of sunrise and sunset and the moon as they move in the course of the year . During the transition from winter to summer the Sun rises every day a little further North than the day before, and reaches the northernmost position at the summer solstice; this provision noted the Heel stone, which was set with striking for that time (2000 – 1500 BC) the accuracy of 0.2°. During the transition from summer to winter every day the Sun rises a little further South than the day before, and reaches its southern most position at the winter solstice; this position is marked by arches. The points of sunrise and sunset in the vernal and autumnal equinoxes are also marked. Thus, in total, six positions of the Sun.
Quite similarly and the Moon rises every night in different points of the horizon, but its movement from the extreme Northern to the extreme southern position occurs much faster than the Sun: two weeks, not six months. Continue reading
It is estimated that there are approximately 200 cave structures, the total length of which nobody knows. This and ancient monasteries, and underground labyrinths of Kyiv fortresses, caves and traps. The origin of some still not installed.
ROOKERY “MOON DEMON”
From time immemorial well-known legend about the great and powerful Serpent, the Dragon dwelling in the cave somewhere on the outskirts of Kiev . To pay off him, residents gave the monster the most beautiful girls. Some researchers strongly argue that Snakes actually existed! And the cave is almost in the heart of the city.
Together with the Vice-President of the club “national secrets” candidate of physico-mathematical Sciences Alexey Glazing we go to snake rookery. We pass a few hundred meters down the slope Current near the street of Frunze, and Leont’ev points to the cave on top of a hill. Continue reading
The basis for determining a constructive solution of large-panel residential building is its structural diagram.
In practice, the design and construction of large-panel buildings used a significant amount of different design schemes, because of the large variety of space-planning decisions, different levels of development of building materials industry and production of precast products, security of construction sites lifting and transport equipment. The importance in the choice of structural schemes is their techno-economic evaluation. Depending on the constructive scheme of the building materials are defined and the nomenclature of assemblies, depend on it the methods of construction of buildings and technical-economic indicators of large-panel construction.
On the constructive scheme of the large buildings, divided into the frame, and frameless buildings with an incomplete skeleton.
Prefab large-panel houses main structure has a frame consisting of columns and beams. The columns of frame are available both at external, n internal walls; girders can be placed transversely or along the building. Continue reading
