The first half of September is behind, but we continue to look for the most interesting events in Moscow in 2018.

• C 16 to 20 September

From September 16 to September 20

40. Concert Odnono

Odnono music is much closer to the spiritual manratram than to any of the "earthly" musical styles, although the last of 10 group albums, Betalab, outlined a significant roll towards the "live" electronics with parties of ethnic tools of various cultural traditions of the planet. On September 19, the team will return to the "16 tons" scene to reiterate the beacon for everyone who seeks to realize themselves in this world. Home - at 20:00.

Until September 20, the exhibition will be held in the gallery "here on Taganka" "here will be the city of Vareni organism" the art group "Vareniya organism", which includes onton Abstore, Mitya Urbi Sokolov, Konstantin Antonov.

"Here will be the city of Vareniy organism," this is a city attraction, a city-simulator, an interactive city and an adventure city. Exposure-manifest of public-art as a psychoactive urban landscape that promotes the disclosure of hidden human potentials. "Here will be the city of Varen organism," - the presentation of the archive of unrealized ideas, sketches and layouts of future projects of the group of artists.

The exhibition will feature printed computer graphics, art installation, video stations. These works, reminiscent of the schemes, or complex synthetic multidimensional spaces, are virtual projects of "non-resident" playgrounds. They form a new landscape space in which the object performs the simulator for a person. For the authors, the idea of \u200b\u200buseful experience, which can be obtained from the artistic work.

"Vareniya Organism" is the Union of Molecules, as the authors of the project call themselves. They transform domestic space into extrasensory, turn cities into huge playgrounds. The union of artists even has a certain mission - to land new synapses through technological games and unusual behavior.

42. Exhibition "Finding My Street"

Until September 17, an exhibition "Finding of My Street" will be inclusive in Moscow Museum. Its discovery is timed to the day of the archaeologist, which is celebrated on August 15.

Again in the halls of the museum you can see unique historical items found by archaeologists on the streets of Moscow recently, from the beginning of 2018. The exhibition of archaeological finds of the 2017 Season 2017 "Secrets of Moscow Dungeons" on the July Moscow Urban Forum 2018 was named the best in the nomination "City Exhibitions".

"The findings of my street" are about 100 artifacts, evidence of various periods of the history of Moscow, which were still literally literally under our feet on the Moscow streets. At the exhibition, guests will see the items of the daily life of Muscovites from the Middle Ages until the end of the XIX century. A significant part of things was found in the territory of Moscow regions, which are not only in historians for hearing, but also in the general public, the charge and the kadasha.

The exposition will include tiles with unusual plots, samples of art medieval founders, ceramics, religious items. You can also see the weapon, for example, the food found almost on the Red Square, or the phenomenal preservation boots, allowing to consider the smallest details of the work of the leather-old leather.

43. SHOW "Ural dumplings. Beach Syuse "

The next humorous show "Ural Pelmeni" this time will raise the topic of vacations and the beach. A real holiday in Russian is when you try to eat as much as possible on All Inclusive; When you are mazed sour cream body burned in the sun; When you are not afraid to swim for a buoy and you carry a suitcase to anyone who is not necessary souvenirs. "Beach Syuse" is declared open.

44. Exhibition "Horugwi XVII century. Monuments of facial sewing "

Within the framework of the project of the show of individual works from the Museum's stakes in the hall of one monument until September 21, an exhibition "Khorugvi XVII century" will be held. It will present two subjects that once included in the temple kit. Horugwi is church banners, without which no congestion does not do.

Compared to numerous preserved spiked coupling and pellets, the Old Russian Horugwi are rare, they can not be seen in the museum halls. Exhibited by Khorugwi sewn from velvet, decorated with fringe along the edges and brushes along the lower blades. On both sides of silk and metal, so-called "zero", threads are embroidered images that are probably associated with the dedications of the throne of the temple.

In this case, this is "Holy Alexy, the Man of God" and "Tikhviny Image of Our Lady", "conception of the righteous Anna" and "Calval Cross". Spectators will be able to admire the skill of the Old Russian craftsmen, see a variety of techniques used in the face sewing of the XVII century, as well as open some secrets associated with the life of these wonderful monuments of art.

The designer can not do without understanding what concrete is what their classes are. The main provisions on the concrete are regulated in DBN B.2.6-98: 2009 "Concrete and reinforced concrete structures", which in Ukraine was enacted since 2011. In fact, this regulatory document is a translation of a similar European standard.

For some designers, the new designation class of concrete has become surprised. Even building organizations that are perfectly dealt with classes begin to make mistakes. In order to make clarity in the designation of the concrete class, this material was written.

The ratio between classes and brands of concrete

It should be noted that the brand of concrete practically no one uses. However, to understand some old typical projects and other engineering solutions, you should remember where you can find a table of compression ratios.

If earlier the concrete class was designated as B20, that now the same concrete class is indicated as C15 / 20. The fact is that in some European countries, such as the United Kingdom, a cylinder is used to check the strength of concrete concrete. He has a height twice the diameter. In other countries, a concrete cube is used to verify strength. Therefore, for these samples, the indicators will be different.

Example. Concrete cl. C12 / 15 means:

• the minimum strength of the cylinder for compression is 12 MPa;
• the minimum strength of the cube for compressing 15 MPa.

15 MPa is that the usual cl. B15, which we use.

Concrete class for strength (c) on dbn	Concrete class for strength (c) on SNiP	The average strength of the concrete of this class R		The nearest brand of concrete on strength m, kgf / cm 2	Deviation of the nearest brand of concrete from the average strength of the class R - M / R * 100%
		MPa	kg / cm 2
-	B0.35	0,49	5,01	M5	+0,2
-	B0.75	1,06	10,85	M10.	+7,8
-	IN 1	1,42	14,47	M15	-0,2
-	B1.5	2,05	20,85	M25	-1,9
-	AT 2	2,84	28,94	M25	+13,6
-	B2.5	3,21	32,74	M35	-6,9
-	B3.5	4,50	45,84	M50	-9,1
-	AT 5	6,42	65,48	M75	-14,5
-	B7.5	9,64	98,23	M100	-1,8
C8 / 10.	AT 10 O'CLOCK	12,85	130,97	M150	-14,5
C10 / 12.5	B12.5	16,10	163,71	M150	+8,4
C12 / 15.	B15	19,27	196,45	M200	-1,8
C16 / 20.	IN 20	25,70	261,93	M250	+4,5
C18 / 22.5	B22.5	28,90	294,5	M300	+1,9
C20 / 25.	B25	32,40	327,42	M350	-6,9
C25 / 30.	B30.	38,54	392,90	M400	-1,8
C28 / 35.	B35	44,96	458,39	M450	+1,8
C32/40	B40.	51,39	523,87	M550	-5,1
C35 / 45.	B45	57,82	589,4	M600.	+1,8
C40 / 50.	B50	64,24	654,8	M700.	+6,9
C45/55	B55	70,66	720,3	M700.	-2,8

The average strength of the concrete of each class is determined by the normative coefficient of variation, equal to V \u003d 13.5% for structural concrete and V \u003d 18% for thermal insulation concrete on the formula

where in - the value of the class of concrete, MPa:
0.0980665 - transitional coefficient from MPa to kg / cm 2\u003e.

Class of concrete and its application in construction

It should be understood that in addition to the class of concrete, it should be taken into account its frost resistance (F), waterproof (W) and a number of other indicators. Often, developers are looking for information about concrete class on the Internet, which must be used for a particular design. There is no direct response to this question. It is necessary to disassemble every individual case, taking into account the existing loads on the design. However, there are general recommendations on the use of a class of concrete.

C8 / 10 (B10) Use for the construction of concrete preparations for monolithic structures. Does this so that when laying a concrete "Milk" did not run into the ground. Concrete preparation also allows you to more accurately monitor the necessary values \u200b\u200bof the protective layer. In some cases, this class of concrete is used to build screens and tracks.

C12 / 15 (B15) It is often used in private construction for all designs that perceive a purely vertical load. These may be foundations, walls, columns, fences, etc. It is not recommended to apply for concreting complex elements of the building.

C16 / 20 (B20) It is almost universally used for concreting monolithic structures, from foundations to retaining walls. It can be used for concreting slabs of overlapping, which do not carry a large load.

C20/25 (B25) Used for the manufacture of pile foundations, scolding under large structures, riggers and beams with a large amount of span. Pools, vertical walls and overlaps are also built from concrete of this class.

C25 / 30 (B30) It is used to build bridge and hydraulic structures, where high strength of concrete is required. Also, this class of concrete can be appointed with complex design conditions.

Ilona quote:

And it does not bother anyone that B15 is interpreted as 15 MPa (according to the European standard) and immediately equal to 19.27 MPa as the corresponding class B15 (existing standard).

Does not bother Niraza. I read and see all the letters. Where the minimum strength is written and where the average strength value is written - it is natural that there will be different numbers here.
Display targets on the screen SPC S-200 SP

A little about shot down IL 20

Since I was in a military school studied the Zenit Rocket Complex C200V and for many years he served on it, I can say the following: Arabs could not confuse F16 with IL 20. This is the same as confused the nail with the comb.

On the screen at the capture operator in the cabin C2 complex C200V, F16 looks like a nail, well, it can be like three nails together, then the IL20, because of the screws, gives a comb on the screen (even such a term in SPR). Such an illumination is given all the brewing aircraft. I will explain: the primary, almost unprocessed reflected signal from the target comes to the screen indicator screen. All surfaces of the reactive aircraft, from which the signal is reflected, stationary. Therefore, the reflected signal is formed from several "brilliant points" of the aircraft, it has about the same frequency and is usually two-days standing near the vertical lines. From the screw aircraft, due to the Doppler effect, the screws on it rotate and give different Doppler additives to the reflected signal frequency) the reflected signal in the form of vertical bands occupies almost the entire screen. These are two kinds of reflected signals, visually well distinguishable. Any training of capture operators, and other members of the combat settlement begins with explaining these differences. I am sure that our specialists who prepared this Arabic settlement were explained to them. Moreover, in the K2 cab of the C200V complex there is a regular target imitator. On it, it is trained L / from operators and a start-up officer and officer-shooting. It provides imitation of all types of objectives, and it perfectly imitates the screw aircraft.

It should be noted that the C200B system is rather complicated in operation and maintenance. In order to put the rocket, you need to make a bunch of different operations. They must be clearly coordinated and with the combat calculation K9 (the management point that gives permission to start) and with the combat calculation of K3, (from which the Division starter is managed. This calculation is preparing a missile to start). Unprepared and untranslated combat calculation is just not able to do this. If they managed to let the rocket, they were clearly prepared and not to know the differences in the marks from the goal of screw and reactive aircraft, simply could not.

I do not know whether the requester is used in Syria. But during my service, the equipment imported abroad, the requesters were not put. It was a technique under the vulture "Top Secret."

There is a version that the Syrian calculation first captured, accompanied and allowed the rocket according to F16, and our plane came to the antenna pattern in the antenna pattern, with a clearly greater efficient reflective surface. The rocket was automatically crossed on it, and a subsection occurred. Yes, this is possible, but only under one condition - on our aircraft it was necessary to "shine" the radar. If there were no reflected signal, the rocket would leave for self-destruction. So, the Arabs our plane was accompanied by a radar, and once accompanied, then the reflected signal from the target was seen on the capture indicator. Moreover, when changing the target, the capture operator itself was manually reloading a new goal for automatic support.

If the type of reflected signal is clearly changed during the target of the rocket, then any combat calculation commander must adequately react - turn off the power. This is a scattering of any calculation. When the polygon is shooting along the winged target rocket launched from the T16 carrier, there is also an empirical ability to capture the carrier instead of CRM. And in all regulatory documents on combat shooting, it is hard to strictly indicate that if the type of purpose changes, it is necessary to instantly stop its support. But the emergence of such a variant of the development of events has a very low probability. The C200V orientation diagram, in the rocket guidance mode, has a width of 1.5 degrees. And, especially in small distances, get into her a random aircraft is very difficult.

In my opinion, Arabs understood that they were accompanied, and let the rocket were consciously. But here the "Corporate Ethics" enters into the case. The most terrible air defense officer is to skip the goal. When we settled on combat duty, we were armed with a pistol. According to youth, we asked our commanders, why we need it. Wise people answered that if you miss the goal, go and shoot, save the paper to the paper. All anti-aircraft missile troops of the country's air defense troops were clear that to stay with rockets on the launcher after the rotation of enemy aviation - to secure a death sentence. Most likely the Arabs perceived these principles, and that was finished into what they saw. But in the evil tricks of the Israeli Air Force as it is weak to believe. They are the opposite of military cooperation with us. And the fact that the Arabs are the most "interesting" objects for Israelis places in the immediate vicinity of the location of our troops, this is no one news. So, gentlemen from the Ministry of Defense should deal with their allies, and not to sculpt us a new enemy.

Since this text is still read, let me make some important, in my opinion, additions.

C200 with military air defense of the Russian Federation removed, in my 1994. After 1991, as far as I know, combat shooting at the landfill in Sary-Shagan (Priozersk) was practically not carried out. As a result: the supervisors of calculations and commander of offices that were at least once shot at the Polygon from C200, now at least 50 years. Commands of batteries and divisions - 60 - 65 years. I do not think that people of such ages sent to Syria to teach their calculations. I have a question: and who and how did these Syrians taught, which were very difficult in service and maintenance complex? The main and main reason for the defeat of your aircraft is a complete loss by the command of the Air Force Air Force and for the actions of its divisions. Over the officer - shooting in the division (K2) another bunch of different bosses, and on K9 (team point of the division group) and on the KP Regiment, and the central KP. They were supposed to have been obliged to ban shooting on our plane. With K9 - just do not give permission to start.

The air defense of the "non-smoking man", itself must, obliged to understand who flies, where it flies and why flies. If they do not know how to do it, it is necessary to learn, and do not figure out the extreme from the outside and disagree the armed forces. But even in 2015, in my opinion, our generals boasted in that they control the airspace within a radius almost 600 km from our air base. But, for some reason, it was not possible to detect two F16 on a distance of 100 km. By the way, C200V was able to knock off not only f16, but also to shoot down controlled bombs running them in flight. We are still at the beginning of 80gg in Sary-Shagan, successfully conducted firing on a shared target, in which it was not destroyed by a carrier, namely the "winged rocket" separated from it. Moreover, the sizes of this winged target missile were very modest, it seems much less than American managed bombs.

In principle, the launch of the missile, provided that the rocket does not see the goal, it is possible. On C200 there is such a mode in which the rocket starts, and only after that captures the target. Called something like "shooting closed target". But, in my opinion, the RLS complex must still accompany something. Although, probably, she can accompany the target from the simulator. Then the capture operator gives AC3, then the AU RPC, and of the Starting - on the mode of a closed target and gives RP. (Start permission). But, anyway, the RP team must come to computer K2 from K9. In this case, the rocket starts, produces a search for a goal in flight, the goal does not find and takes sharply up (angle 86 g) and after some time it produces self-control. From the ground it can be seen as well as under the goal.

When undermining the rocket, a cloud of special balls is formed, now I do not remember, Toli 35, Toli 55 thousand pieces, in the form of a toroid (bagel) with a radius of 200 meters. If someone goes there, consider gone. There will be a lot of holes in the case. Like a durslak. On the screen of capture indicators and IO, you can only determine the type of purpose. Screw, rocket, turbojet or jet plane. If the goal changed its type sharply, then the training commander of the combat calculation immediately turns off the power and will send a missile to self-destruction. Everything depends on the calculation. I have another version: the Arabs could take IL20 for the pen. It gives a high drop on the screen. But obviously one, command of and our Air Force and the Arabic forces of air defense explicitly lost control over the air situation and for the actions of its divisions. And Bardak - he is expensive.

Here are pictures here. Looks like half-band will figure it out. But in the pictures perfect images. In fact, the multi-airplane "sews" the entire screen.

Shrimp trading fishery has a thousand-year history. And to the very recently, sellers (fishermen) and buyers had disagreements about shrimp prices. How to determine it? On weight? Casual?

The problem is that in one catch of shrimp can be caught both large and small. It is clear that large shrimps are in great demand and should cost more. To make it more convenient to buyers and sellers, shrimps began to sort in size and then sell on weight. Thus were adopted by trade standards on the size of the shrimps, which fishermen, sellers and cooks worldwide are used.

What do shrimp dimensions mean

When you buy shrimps in the weight package, look at the etiquette. In addition to the data on the manufacturer and the place of catch, it will necessarily stand figures, for example - 13/15 or 27/34. What are these numbers?

This is the number of shrimps per 1 English pound or 1 kilogram of weight. The packaging indicates which weight measurement units are used.

Those. In 1 pound of shrimp will be from 13 to 15. And in one kilogram from 27 to 34.

In one kilogram of 2.2 pounds. The measurement system depends on the country of the manufacturer.

In Russia, you can find a size of 1 pound and 1 kilogram.

Sometimes the shrimp packaging may be the designations U / 15 or U / 10. This is the designation of large shrimps and means "Under 10" - "under" or "about" 10 pieces in one pound.
These sizes of shrimp are also called caliber and are considered an international trading standard.

Some Argentine shrimps (red deep-sea) are marked with C1, C2, C3, CR and L1, L2, L3 and LR.

• The letter C means that shrimp without a head, and L - with a head.
• The letter R means that the size of the shrimp can be any of 30 to 150. Such shrimps are called non-calibrated.

Also on the package can be written 90+. This means that in 1 kilogram will be from 90 pcs shrimp.

Shrimp size - Number of 1 pound shrimp / kilogram

For the convenience of buyers, we give a table of size of shrimp per pound and equivalent to a kilogram. Dimensions are indicated for raw fresh shrimp without head. For boiled ice cream shrimps as well as shrimps with a head number of pieces is indicated by a kilogram.
