“Under the President’s control”: revival of the PMK

General information The mitral valve is located between the left atrium and the left ventricle. Mitral valve prolapse (MVP) is a heart defect in which the mitral valve leaflets bend into the left atrium during contraction of the left ventricle. Normally, during contraction of the atrium, the valve is open and blood enters the ventricle. Then the valve closes and the ventricle contracts, causing blood to be ejected into the aorta. With MVP, prolapsed “bending” of the valve leaflets during contraction of the left ventricle leads to the fact that part of the blood flows back into the atrium. Clinical signs of MVP appear only with pronounced reverse blood flow. This defect usually occurs in young people, most often in women aged 14 to 30 years. In most cases, MVP is asymptomatic, does not lead to cardiac dysfunction, and is an incidental diagnostic finding during cardiac echocardiography (ECHO-CG). In rare cases, the amount of backflow of blood is large and correction of the defect is required, including surgical intervention.

general information

Secondary battery guns are included in the Hull module as auxiliary caliber guns - their number can be changed when installing another hull.

As a rule, this type of gun has a similar caliber to the guns of destroyers or even cruisers, but has less range and damage. Thus, the secondary gun serves to combat targets that come close to the ship. In this case, the secondary gun can only use high-explosive fragmentation shells.

By location we can distinguish:

  • onboard PMC installations, which are located to the left and right of the ship’s symmetry plane;
  • central installations of PMK.

If secondary battery guns are universal, then their functioning as air defense occurs in parallel and does not affect the fight against surface targets.

The secondary gun increases the visibility of a ship from aircraft by 2 km; the effect lasts 20 seconds after the last shot.

If an enemy ship is destroyed with these weapons, the “Melee Master” achievement is awarded.

What is a secondary gun (mine-resistant caliber) in World of Warships

A mine-resistant caliber is an additional weapon on a warship that is installed on the ship along with the hull. These guns have a small caliber, there are quite a lot of them (depending on the level of the ship) and they are constantly activated, regardless of the user’s wishes.

Anti-mine guns fire automatically and allow you to fight at close range. That is, they automatically attack all enemy ships that sail too close to you. The range and damage from these guns is not so high, in addition, they attack exclusively with high-explosive shells, but even such a small help sometimes allows you to emerge victorious from an unequal duel.

Improving passive weapons

Despite being a passive weapon, it can still be upgraded thanks to various "Signals" and commander skills that allow you to increase the range and power of this weapon. Is it effective? Without a doubt! Together with the main weapons, these, at first glance, not very powerful weapons, allow you to inflict critical damage , inflict additional damage and warn the enemy in advance that it is not so easy to compete with you.

Remember this unique capability of the ship and you will always be able to find a way out of even the most difficult situation.

Firing

The secondary gun fires automatically and a number of rules apply:

  • the guns fire at the nearest enemy ship, taking into account the action of the sector system: if the enemy ship is located on the side, then both the guns on this side and the central guns fire;
  • if the enemy ship is perpendicular to the side (in front or behind), then either only the central installations, or a number of side installations will fire - but only in a narrow sector;
  • if there are several enemy ships near the player, then the central guns will prioritize the closest target, but the side guns will fire at the targets closest to each side.
  • in case of selecting a priority target (CTRL + right-click on the required enemy ship), all secondary guns capable of firing at this ship will only shoot at it, the remaining secondary guns will fire at the targets closest to them;
  • If the ship commander’s skill “Manual secondary gun fire control” is used, then fire will only be fired at the selected target.
  • What it is

    Mitral valve prolapse (hereinafter referred to as MVP) is the most common valvular pathology of the heart. The disease affects approximately 2.5% of the world's population. It is often found in children and adolescents. The predominant number of patients are women and girls.

    MVP is distinguished separately from valvular heart defects for two reasons. Firstly, the anomaly has a different nature of occurrence. Secondly, unlike heart defects, this pathology is benign, but can also have unpleasant consequences. Often a person does not know about its presence: MVP becomes an “accidental finding” during a medical examination or examination for another disease.

    To understand the essence of this disease, it is important to understand the process of valve operation. The human heart has 4 cavities, or chambers. Normally, blood circulates in only one direction: from the atria to the ventricles, then to the large vessels (aorta and pulmonary artery). This is possible thanks to the synchronous operation of the valves, which open and close at the right time. Closed valves prevent regurgitation - the direction of blood flow in the opposite direction.

    With MVP, its main function is disrupted. During the systole phase, when the left ventricle contracts, the valve leaflets cannot withstand the blood pressure and begin to protrude into the cavity of the left atrium. The main problem is that some of the blood returns to the left atrium. This is called regurgitation. All the ensuing adverse effects of MVP are associated with this process. Severe regurgitation can lead to disability.

    Improving the characteristics and survivability of secondary guns

    The effectiveness of guns of this class can be increased:

    • ship commander skills:
    1. "Desperate" ;
    2. "Basic fire training";
    3. "Enhanced fire training";
    4. "Manual fire control of secondary guns".
    • upgrades:
    1. "PMK Modification 2";
    2. "PMK Modification 3".
    • signal Mike Yankee Soxisix. Although you can also increase the likelihood of a fire on an enemy ship by using Victor Lima and India X-Ray signals.

    The survivability of secondary battery installations can be increased by 100% using the “Auxiliary Weapons Modification 1” upgrade.

    Unique upgrades of some Tier X ships can also affect the characteristics of the secondary battery.

    Description and purpose

    The PMK can be deciphered as “full face mask box”. It refers to military filter devices to protect the respiratory system, eyes and skin from harmful chemicals and other impurities. In this case, the oxygen content in the atmosphere should not be less than 18%, since the gas mask does not have its own independent oxygen supply system, as in PPE (personal protective equipment) and hose respirators.

    PMK gas masks are quite reliable and versatile, providing good audibility for negotiations. The large filter reserve allows you to stay in it around the clock.

    However, the shelf life and storage conditions of the filter box are the most important, since it has a limited time of use.

    Today, there are many different types of gas masks and brands of filters designed for certain substances that cannot exceed 82% of the total air volume. These products are effective against radiation, vapors, most toxins, gases and airborne aerosols, including viruses and bacteria.

    In accordance with the scope of application, in addition to military, there are models:

    • civilian (adults or children);
    • industrial.

    The first ones do not require additional skills when using , but every simple person hopes that they will never be useful. The latter are an important tool for the survival of intelligence officers when performing dangerous work.

    Deciphering the PMK gas mask makes it clear that it is much more effective compared to a simple respirator for the mouth and nose.

    When it comes to performance and protection, the PMC is truly the best option. Serves as a rescue from quickly and slowly acting chemical warfare agents (chemical warfare agents):

    • biological and chemical weapons - dangerous pathogens that cause epidemics, non-lethal and lethal toxic substances, tear and irritant, nerve-paralytic, psychogenic and asphyxiating substances;
    • aerodispersed cloud of radioactive substances;
    • To protect the organs of vision from nuclear and thermonuclear light radiation, special films (PSZG-2) are used.

    Team "Builder" (PMK-196). 1972 -1976

    100 years of Ochakovo football

    PMK - mobile mechanized column. Powerful construction organization in Ochakov. In the 60s, in Ochakov there was a section from the Nikolaev PMK-191. At the end of 1968, a separate PMK-196 appeared. The head at that time was Bryzgalov Anatoly Ivanovich , the chief engineer was Ermolin Nikolay Andreevich . The brigade built mainly in the region, but did not forget the city. For example, the regional central district hospital was built by them. In 1972, the acting head of PMK-196 was Ermolin, the chief engineer was V.S. Andryushchenko. In 1975, Ermolin left and Nikolai Igorevich Rusov .

    Like many organizations in Ochakov, PMK-196 also had a football team - a participant in football competitions in the first half of the 70s. The weather didn’t make any difference, I was at the bottom of the standings.

    “Since September 1972, the Ochakov Championship began in honor of the 50th anniversary of the formation of the USSR. 6 teams are participating: “Builder” (SU trust “ChKS”), “Yunost”, “Builder” (PMK-196), “Zarya”, “Storm”, “Falcon”. Results of the first games: Stroitel (PMK-196) - Zarya - 2:6, Storm-Yunost - 5:0, Sokol-Stroitel (SMU) - 0:3 goals: B. Yakovlev, E. Vaskov (two)"

    The main organizer and driver of the team was Evgeniy Andreevich Kharchenko. He worked at PMK as an electrician, then as a power engineer. There were many trainees in the organization - from vocational schools in Nikolaev and Bashtanka. The main bet was placed on them. But trainees are not a permanent thing. It was not always possible to assemble a team for regular participation. The team disbanded in 1976, leaving its small mark in the history of Ochakovo football.

    About the company

    The history of our enterprise began on June 1, 1950 - the day when the decision was made to create a land reclamation station in Zhlobin. Over the past 60 years, the state organization has been repeatedly reformed, renamed, and its financial and economic potential and status have changed. Only one thing remained unchanged - she was always fruitfully engaged in the production of irrigation, cultural and technical, water management and construction work.

    Over the past years, the team has done a huge amount of work to renew the lands, increase their fertility, and involve swampy, unproductive and unused areas into agricultural rotation. While maintaining previous experience, PMK has significantly expanded its range of work. Various types of road, industrial, agricultural and civil construction have been mastered. In-house production has been expanded, the fleet of machinery and mechanisms has been updated, advanced construction technologies and management of the quality management system for construction work have been introduced. Through the efforts of the team, a number of important and prestigious objects have been erected in the district and region.

    What is mitral valve prolapse or MVP?

    After performing echocardiography, the doctor makes a diagnosis of “mitral valve prolapse (of such and such) degree (usually the first).” What does this mean and how dangerous is it?

    There are two types of mitral valve prolapse: true (congenital) and acquired.

    True mitral valve prolapse is either a separate disease or a manifestation of diseases such as Marfan syndrome, Ehlers-Danlos syndrome and others.

    True mitral valve prolapse is based on myxomatous degeneration of the mitral valves, which manifests itself in a disruption of the structure of connective tissue. Due to a hereditary defect in its synthesis, this valve is thickened and changed in shape.

    Acquired mitral valve prolapse can develop due to weakening or rupture of the chordal filaments that hold the valves; or, for example, dysfunction of the papillary muscles from which the chordal filaments arise. This condition can be observed, for example, in coronary heart disease, myocarditis, cardiopathy, and heart attacks. In some cases, the cause of acquired mitral valve prolapse is rupture of the chordal filaments.

    And the greater and more serious the damage to these threads, the more pronounced mitral regurgitation will be.

    From an anatomical point of view, prolapse is a deflection. The mitral valve is a valve that is located between the left atrium and the left ventricle. The mitral valve's job is to allow blood to pass from the atrium into the ventricle and not let it back out. Normally, the mitral valve opens in one direction and does not open in the other. With prolapse, one or both leaflets of the mitral valve sag into the atrium, allowing some blood back into the atrium. The higher the pressure in the left ventricle, the greater the deflection of the “faulty” valve.

    Firing

    The secondary gun fires automatically and a number of rules apply:

    • the guns fire at the nearest enemy ship, taking into account the action of the sector system: if the enemy ship is located on the side, then both the guns on this side and the central guns fire;
    • if the enemy ship is perpendicular to the side (in front or behind), then either only the central installations, or a number of side installations will fire - but only in a narrow sector;
    • if there are several enemy ships near the player, then the central guns will prioritize the closest target, but the side guns will fire at the targets closest to each side.
  • in case of selecting a priority target (CTRL + right-click on the required enemy ship), all secondary guns capable of firing at this ship will only shoot at it, the remaining secondary guns will fire at the targets closest to them;
  • If the ship commander’s skill “Manual secondary gun fire control” is used, then fire will only be fired at the selected target.
  • Frequent symptoms

    Most people with “harmless” mitral valve prolapse, especially children and adolescents, have an asymptomatic course of the disease and nothing bothers them. Sometimes patients complain only of minor chest discomfort. I would like to note that the clinical picture may not correspond to the degree of pathology.

    Symptoms of mitral valve prolapse:

    • pain in the left side of the chest or behind the sternum: stabbing, pressing, squeezing, moderate intensity. The duration varies from a few seconds to a day. Pain can occur either during a strong experience or performing physical exercise, or spontaneously, for no apparent reason. Often the unpleasant sensation is accompanied by a feeling of lack of air, the appearance of cold sticky sweat, anxiety and even fear of death;
    • dizziness due to low blood pressure;
    • rapid heartbeat, sensations of “interruptions, rolling, freezing” in the chest;
    • frequent pre-fainting conditions, in which a person experiences a feeling of lightheadedness and nausea, accompanied by flashing spots before the eyes and blurred vision;
    • with severe and prolonged mitral regurgitation, signs of congestive heart failure are added - difficulty breathing, rapid onset of fatigue, swelling in the legs, especially in the evening, heaviness in the right side due to an enlarged liver.

    Also, in people with mitral valve prolapse, often due to hereditary connective tissue disorders, I observe symptoms of autonomic dysfunction:

    • constant pressure changes;
    • fainting;
    • increased sweating;
    • neurotic disorders - such patients are usually anxious and suspicious, suffer from various phobias, hypochondriacal and obsessive-compulsive neuroses, they often invent non-existent diseases;
    • “chilliness” and cold fingers and toes;
    • increased sensitivity to cold;
    • vegetative crises, better known as panic attacks.

    The effectiveness of guns of this class can be increased:

    • ship commander skills:
    1. "Desperate" ;
    2. "Basic fire training";
