Ducts are channels or pipes through which air circulates. They are a constructive element of ventilation systems that provide indoor conditions suitable for life and work. But the air contains suspended particles of dust, dirt and even microbes. All this settles on the walls of the air ducts, which leads to a narrowing of their clearance. The result is a decrease in thrust, stagnation of air and the creation of conditions hazardous to health. In order not to bring ventilation to such a state, its channels must be cleaned at regular intervals established by law.

Ventilation and law

Since people's health largely depends on the state of ventilation in residential and working premises, the law strictly controls all related processes:

  • design;
  • mounting;
  • cleaning;
  • repair.

The measures to be taken to maintain the normal operation of ventilation are defined by the articles of the Federal Law No. 52 of March 30, 1999 “On the sanitary and epidemiological well-being of the population”. Their non-compliance threatens with the onset of civil liability. This law is supplemented by Government Decree No. 390 dated April 25, 2012 “On the fire regime”. It establishes the terms for cleaning ventilation and prohibits the use of flammable and flammable liquids for this.

Stages of cleaning ventilation systems

Ventilation cleaning is carried out in four 4 stages:

  1. inspection of the system to determine the causes of impaired air exchange.
  2. Drawing up a list of works necessary to restore normal air exchange.
  3. Execution of work according to the plan.
  4. Evaluation of the effectiveness of completed work.

Attention! According to regulations, ventilation must be cleaned within 30 days after its inspection .

Ventilation system inspection

The survey includes:

  • study of technical documentation;
  • verification of the conformity of the system to the project;
  • visual inspection for visible damage;
  • measurement of microclimatic parameters and their comparison with established standards.

After completion of the examination, a conclusion is drawn up. It reflects the actual state of the ventilation system, which determines the procedure and types of work to clean it.

Drawing up a work plan

The plan usually includes the following steps:

  1. Choice of cleaning method.
  2. Choice of cleaning products.
  3. Mathematical calculation of the expenditure of these funds.
  4. Collection of cleaning equipment. At the same stage, equipment is prepared to equip the ventilation system, if necessary, to restore or increase its efficiency.
  5. Announcement on the timing of the work.
  6. Dismantling of individual elements of the ventilation system.
  7. Cleaning and disinfection of canals.
  8. Reassembly of the system, installation of previously selected equipment.
  9. Preparation of documentation and registration of entries in the journal.
  10. Checking the effectiveness of work.

The list of works may vary depending on the characteristics of the object, the type of ventilation and the degree of its contamination.

Cleaning procedure

Cleaning of air ducts is carried out in the following order:

  1. Preparation of cleaning agents.
  2. Calculation of the cost of funds for each of the ventilation sections.
  3. System preparation. Dismantling of air intakes, grilles, covers and other elements that interfere with cleaning.
  4. Channel cleaning.
  5. Cleaning of regulating mechanisms (they are not subject to dismantling).
  6. Cleaning filters, their treatment with a disinfectant composition.
  7. Fan cleaning.
  8. Cleaning of heat exchange elements.
  9. Cleaning the drainage system with preliminary removal of the trays.
  10. Cleaning of mixing chambers from the inside.
  11. Cleaning of air conditioners.

The final step is drying the cleaned surfaces. They are collected dry.

Performance analysis

Cleaned ventilation should not have visible contamination. Samples taken from various parts of its inner surface should not contain pathogenic microbes. The system should ensure the formation of indoor microclimate necessary to maintain people's health.

Performance analysis includes:

  • visual inspection of the system;
  • microbiological examination of samples taken from filters, heat exchangers, trays and other ventilation elements;
  • laboratory and instrumental tests to check quality compliance with established standards;
  • comparison of air inflow and outflow (they must be equal).

When checking, it should be borne in mind that different standards are established for different types of objects. If the survey results match them, that's it. If during the check of the system violations were detected, a second cleaning is carried out.

What characteristics to look for. Important parameters and models to look at.   The form

The most important thing in thebest gaming mouseis a comfortable body shape. However, this is an extremely subjective factor, so ideally you need to hold the device in your hands before purchasing. If this is not possible, focus on past experience. For example, you already have a comfortable mouse, but it is not suitable for games - in this case, ask for advice on the forums and thematic groups. This will help you not make the wrong choice blindly.

Most models can be divided into two categories: ergonomic and symmetrical. The former take into account the natural curve of the palm and have recesses on the sides for a comfortable grip. Their main advantages are the low load on the brush and the speed of the cursor. Usually ergonomic models are large and sharpened for right-handers.

Left-handers should look at models with a symmetrical body. They also fit different types of grip. The compact mouse is controlled by your fingertips, which increases the accuracy of pointing. Large models are designed for a "claw" grip with a high click rate.

The weight

Another extremely important parameter. A mouse that is too light will impair pointing accuracy, a mouse that is too heavy can simply be uncomfortable. The optimal weight is about 90 grams.

Some models are also equipped with a system of weights, with the help of which the user himself selects a comfortable weight. However, this significantly increases the final price of the device and can become a distraction: the player will constantly think whether he has placed enough weights. Therefore, it is better to choose a mouse whose weight suits you initially.

Sensor type

Modern gaming mice use laser and optical (LED) sensors. The difference between them lies in the type of illumination: the former use a laser to read the surface, the latter use an infrared diode.

Over the years, both technologies have evolved to the point where they will suit most gamers, but now many more models use optics. The reason lies in the cheapness of such sensors.

Laser mice are more sensitive and can work on different surfaces, even glass. Optical need a special mat.


Most gaming mice can operate at extremely high sensitivity - up to 16,000 DPI. The larger this value, the faster the response of the cursor and the greater the distance it will travel for the same mouse movement.

However, such extreme values ​​are almost never needed anywhere, even in fast-paced online shooters like Overwatch. Therefore, most will have enough sensitivity up to 5,000 DPI.

Connection type

A few years ago, it was believed that a gaming mouse must be wired. With the development of technology, this rule has lost its relevance, and now there are enough wireless models for gamers on the market.

Most gaming solutions connect via their own radio channel and come with a USB receiver. There are also models that work via Bluetooth, but this type of connection is worse due to a less stable signal and higher latency.

If the type of connection is not important, you should keep the price in mind. Good wireless mice are significantly more expensive than their wired counterparts, and no one has canceled the need to charge them every couple of months or change batteries.

Additional buttons

In gaming mice, the set of buttons is not limited to standard LMB and RMB. Almost all models have additional keys on the sides, to which certain actions can be assigned. 

To program such buttons, manufacturers release special software that can be downloaded from official sites. With it, you can reassign keys and install macros on them - an algorithm of actions of almost any complexity.

Such features will be useful not only for gamers, but also for advanced users who work in office programs and IT development environments.

Types of cryptocurrency bots A robot (bot) is a program that has a certain algorithm. It buys or sells assets depending on the market situation. The first trading robots appeared in 2012, and since then they have become more and more perfect. According to some estimates, in Forex and binary options, more than 90% of short-term transactions are made either by bots or with their participation.

There are 4 types of cryptocurrency trading bots:

  • Arbitrage - works on two or more trading floors, the main income is on the difference in rates between them.

  • In a Telegram channel — Search for buyers or sellers in Telegram.

  • Bots for collecting cryptocurrency through faucets. Faucets are online services that distribute Satoshi or other pennies in cryptocurrency for free. They are quite well protected from bots and require captcha. Until it is written, there are only promising, but not ideally working, developments of good robots that can make good money on faucets.

How does a robot trader work?

Bots for automatic cryptocurrency trading work according to special algorithms, trading strategies, which, in turn, are created on the basis of technical analysis of patterns. An independent analysis will require historical data on course changes (charts for at least the last year), sometimes it is possible to find a connection with the news. In addition, after identifying patterns, the strategy is tested on the same historical data, and the number of potential losses and profits is calculated. And with satisfactory results, on their basis, the rules of the trading strategy of the robot for the exchange of cryptocurrencies are created. Some bots additionally use indicators that allow you to analyze the current market situation, while others are launched only when certain market conditions occur. Learn more about kucoin trading bot

The trading strategy for exchange and arbitrage bots can be very simple, for example:

  • When the price of a cryptocurrency goes down, you need to buy it.

  • When the price rises, it must be sold.

Or much more difficult. The algorithm can take into account the latest historical data, indicators and be guided by signals. High-quality bots analyze more than a hundred parameters when placing orders. In some programs, the algorithm does not change, but there are bots for which you can connect or configure additional parameters. This option is well suited for experienced traders who prefer their own trading style. Standard bot can:

  • Assess the market situation, follow the course for a certain period of time, make a forecast.

  • When trading manually, it can give signals to the trader.

  • Create sales or purchase orders.

  • We provide reports on profit or loss.

Snow on the monitor and outside the window. Skyrim was lucky not only with the stylish 11-11-11 release date, but also with the weather, at least in the suburbs. Only one annoying trifle spoils the climatic harmony - on Earth, unlike Tamriel, dragons do not fly.

There in the north

The province of Skyrim wins the heart at first sight. Harsh polar panoramas are not unusual in RPGs, but they are usually served as part of a standard layer cake of green oaks, deserts and tropical beaches. Here - Scandinavian beauty and nothing more. Tall mountains with white glacier caps, gigantic ruins, sparse forests with yellowed birches and lava fields overgrown with brown grass. On clear nights, the northern lights shimmer in the sky, and if nature gets angry and sends a snowstorm, the area is covered with procedural, almost real snow. The music of Jeremy Soul fits perfectly on the picture, as if he remembered that he once wrote melodies for the congenial Icewind Dale.

Hide from the weather in some dungeon, and your eyes will see a spectacle that is in no way inferior to landscapes. Viking tombs with carved ornaments on stone, the golden splendor of Dwemer settlements, ancient temples shrouded in an ominous dove-gray haze... Perhaps the artists of Bethesda have never painted so atmospherically.

Of course, sooner or later, angry Nordic skeletons surrounded by pot-bellied urns will stand across the throat, but this sad moment will not come soon. Skyrim captivates with openness and, like a shock opening theme, calls for adventure. The absurd "autoleveling" of enemies and trophies that poisoned Oblivion to the marrow has been minimized. The authors deftly balance between common sense and the desire to challenge the player. Many areas are safe for beginners, but caves with especially expensive stuff or giants guarding mammoth pastures will knock you off your feet. Take note of the impudent ones, so that later you can return and certainly fight back.

Travelers' club

Actually, fantasy tourism has always been the main entertainment in The Elder Scrolls. Citizens who come for a rich story, I advise you to direct your stops to The Witcher 2 or Dragon Age 2. With the storytelling, TES has troubles from birth - as in the previous parts, the chain of main quests is short and dull. Don't expect colorful NPCs, engaging conversations, and lots of fateful branches. The wanderings of the “Dovakin” hero, whose goal is to destroy the dragon Alduin, who brings death to all living things, will end without leaving bright moments in his memory.

Therefore, it is better to quickly skip through half a dozen starting quests, learn "shouts" (spells in the dragon dialect: spit fire, freeze, telekinesis, a teaser that distracts enemies ...) and immediately dive into the depths of the side quests. Fortunately, there is where to go: four guilds (mercenaries, mages, thieves, assassins) with large "lines" of missions, detective investigations in nine cities, assignments from local residents, dangerous but profitable work running errands for capricious Daedra, participation in the civil war on the side Empires or separatists led by the regicide Ulfric... Phew!

It's amazing how Bethesda manages to bleed plot polymers over and over again in such a rich universe. The threepenny directing of key scripted scenes is painful to watch, and episodes that Obsidian or BioWare would turn into spectacular drama are derailed. Take at least the peace negotiations between the Imperials and the fighters for the independence of Skyrim, where our ward acts as an arbitrator. A good opportunity to hone the skill of persuasion! But no, everything is reduced to a toothless division of capitals.

Smoked scrolls

In general, as usual, extracurricular activities are much more cheerful than those offered by the script. There are hot political strife, espionage passions, and moral dilemmas ... Yes, and valuable goods - powerful weapons and armor, unique talents (werewolves! ghostly killers!), High-impact horses with flaming eyes - they give out just for them. Well, to make the music last forever, the game comes up with random missions on the fly, using a bunch of ready-made templates like “kill <name> in <location>”. These "radiant quests" are actually almost 20 years old - they were thrown back in Daggerfall. Only there is nothing to motivate for RND()-feats. A hero whose pockets are already swelling with gold doesn't need a tip, and there are no Munchkin joys like experience in The Elder Scrolls.

There isn't much here at all these days. Basic stats have been simplified to health, energy and mana indicators. Forget about strength, endurance, intelligence and other parameters of the role-playing system, forget about classes. Secondary talents (running, jumping and others like them) are cut to the root, the survivors are divided into three categories: military, thieves and witchcraft. As expected in TES, the more often we use the ability, the better we own it. True, each now has a modest bush with "perks" that give different bonuses. Open them, of course, not immediately, but in the course of development. If you want, for example, to stun opponents with a shield, take the trouble to increase “Block” to 30.

Otherwise, Morrowind and Oblivion veterans will feel right at home. For those who want to know what happened to alchemy, enchantment, blacksmithing and a good dozen familiar elements, I recommend an overview of game mechanics on our Tamriel Chronicles. By the way, purists who despised TES 4 for quest GPS markers and instant travel around the map can grab their pitchforks again. However, someone is surely sculpting a "hardcore" mod for the most stubborn fans. Look, the Creation Kit is not available, and enthusiasts have already screwed a semblance of Google Street View to Skyrim.

It is a pity that the design of dungeons cannot be cured with patches. Having solved the problem with monotony and "copy/paste", the developers called out another trouble - "Call of Duty syndrome". Whatever the crypt, the rectum with short lateral processes. Truly multi-tiered maps do not exist. You can’t get lost in these one and a half pines, even if you suffer from topographic cretinism since childhood. You know, Bethesda believes that the modern public will boil their brains from a normal maze. Yes, and from puzzles too, otherwise why hang the answer on the wall next to the problem?

“Here again, Moscow lost its head”

Bethesda, like BioWare, resembles a gardener who cuts dead branches from an apple tree every autumn and does not plant young ones. Daggerfall - Morrowind - Oblivion - Skyrim. The prettier the wrapper, the simpler the ideological content. Well, they took down the nightmarish Oblivion portals, replaced them with winged reptiles. Creatures inspire fear both in appearance and screams, circling predatory over the plains, searing the skins of stray bears, but after landing they die in a matter of seconds. Moreover, it is not only our Dovakin who is quick to punish, but also a caudle of ordinary guards with flimsy bows (and we stand at a distance and absorb dragon souls).

There are also a lot of old birth pains. Clumsy "stealth" is again experiencing patience. The characters shine with patent leather and move as if they are on a diet of aspen stakes. Close combat, despite the brutal finishing a la Fallout 3, is still sketchy. Physics brings wild curiosities - type in YouTube "skyrim basket" or "skyrim glitches" and get ready to laugh until you drop. It’s also amusing that under the “new engine” Creation Engine, a retired Gamebryo is hiding - grandfather just got a couple of facelifts.

Although the interface should not be touched. Although he is a kilometer taller than the ugly Pip-Boy 3000 in Skyrim, I really want to meet the creators of this miracle and ask what (and what) they were thinking. Why, looking into the backpack, every time I have to scroll through the category column in order to pull it out on the screen in its entirety? Why is there so much space reserved for 3D models and mean descriptions of belongings? Maybe we should expand the second column with the names of things and add icons? Who forced us to rush through the lists of weapons and accessories in search of what is worn on the avatar? How did information about diseases and other status effects end up in the "Magic" section? Check скайрим моды at this source.

The PC version adds fuel to the fire of irritation. The cursor in a strange way "misses" past the desired line in the dialog and falls into the next one. “Hot” keys 1-8 can only be fixed through the console system of “favorite items”: in order for a blade or spell to be registered in the quick selection menu, they must first be selected by pressing F. And to directly from the inventory - shish. It's time to demand compensation for the inconvenience - clear textures, honest shadows, DX11 goodies ... Alas, the latest waves of technological progress have not reached Tamriel. Probably next time?

Until then, we have Skyrim, which will take dozens of hours to walk around. Full of flaws and broken hopes, like any Bethesda game, but at the same time enticing and interesting. Wait for a couple of patches, download the most useful mods, tighten the screws in SkyrimPrefs.ini, and the virtual Christmas holiday is guaranteed.

Support for NVIDIA 3D Vision technology: 7 out of 10

As of this writing, Skyrim only officially supports the 3D Vision beta driver. And, although the game is rated "Excellent" in it, the shortcomings literally blind the eyes. Or rather, one, but bright - any luminous objects: candles, reflection on armor, etc. palpably double. This is especially noticeable in dungeons. In addition, in stereo mode, the rendering speed significantly “sags”. It is necessary either to take a second card for SLI, or to strangle the video toad in yourself and lower the quality in the graphic settings. Technology testing equipment provided by NVIDIA.
