Abstract: Изобретение относится к системам пожарной безопасности стационарных и мобильных объектов, функционирующих в высокоширотных регионах. Способ повышения эффективности тушения пожара в модуле предусматривает продувку горящего объема модуля наружным воздухом посредством подачи его вентилятором при открытых входном и выпускном люках. Согласно изобретению на вход вентилятора извне подается снег и/или вода в зависимости от температурных условий. При этом снег подается персоналом вручную лопатами и/или снегометной снегоочистительной установкой, а вода подается вручную ведрами и/или пожарными стволами. В результате падает среднеобъемная температура, замедляется или вообще прекращается горение, а продукты горения удаляются наружу, чем обеспечивается безопасность персонала, облегчаются действия пожарных подразделений и становится возможным скорейшее восстановление объекта. 2 з.п. ф-лы, 2 ил.

Abstract: FIELD: medicine, namely to traumatology and orthopedics. 
     SUBSTANCE: invention relates to medicine, namely to traumatology and orthopedics, and can be used to select the mode of postoperative rehabilitation after revision hip replacement in patients with extensive bone defects in the acetabulum. After combining the preoperative model of the pelvis and the acetabulum component, its virtual removal is performed and, thus, an imprint of the planned contact surface of the acetabulum component is obtained on the bone bed of the acetabulum area. Next, the area of the resulting print is determined. A postoperative pelvic model with an implanted acetabulum component is combined with a preoperative pelvic model using identically installed points. Then the postoperative pelvic model is removed, retaining the acetabulum component. Then, the implanted acetabular component is removed from the preoperative pelvic model and, thus, an imprint of the actual contact surface of the acetabular component installed during the operation is obtained. The area of the resulting print is determined. The percentage of the footprint area of the actual contact surface to the footprint area of the planned contact surface is calculated. If the obtained value of the actual contact surface is more than 60% of the planned one, a postoperative rehabilitation regime is chosen, which involves walking with a dosed load on the operated limb for 4 weeks with two crutches, then another 2-4 weeks with one crutch, and then 2-4 weeks with a cane; if the obtained value of the actual contact surface is less than 60% of the planned one, a postoperative rehabilitation regime is chosen, which involves walking with a dosed load on the operated limb for 8 weeks with two crutches, then another 8 weeks with one crutch, and then 8 weeks with a cane.  
     EFFECT: method provides prevention of the development of aseptic loosening of the revision acetabulum component of a high complexity of the geometry of the contact surface, as well as improves the effectiveness of hip replacement by determining a rational rehabilitation regime based on an assessment of the area of the actual contact surface of the installed acetabulum component with a bone bed.

Затем определяют среднесуточное количество локомоций в тысячах шагов. Далее определяют уровень привычной двигательной активности (ПДА) по среднесуточному количеству локомоций в тысячах шагов. Далее рассчитывают коэффициент нормативного соответствия массы тела к суточному количеству локомоций по формуле масса тела в кг/суточному количеству локомоций в тысячах шагов. Затем исходя из уровня привычной двигательной активности проводят центильное распределение по коэффициенту нормативного соответствия массы тела к суточному количеству локомоций. Затем в случае определения менее 25 или более 75 центиля коэффициента нормативного соответствия рекомендуется изменить двигательную активность ребенка.

Abstract: FIELD: oil and gas industry.  
     SUBSTANCE: group of inventions relates to the oil and gas industry, namely to methods for hydraulic fracturing of a productive formation (fracking) in boreholes. The method includes the descent in the casing of at least one hydraulic fracturing coupling consisting of a cylindrical body with radial holes in which plugs with bursting membranes and covers are installed, into a given interval of the borehole, cementing of the backwater space. Before assembling the coupling, the membranes are manufactured with the ability to withstand a pressure no less than 7% greater than the pressure of the casing crimping.  Each lid is equipped with a central hole, which excludes the leakage of viscous liquid pumped into the cavity of the plug when descending into the well. The viscosity of the liquid in reservoir conditions, the thickness and diameter of the hole in the lid are selected so that after the rupture of the membrane, this liquid flows out through the hole, and the lid does not collapse at a pressure lower than the pressure of the hydraulic fracturing after cementing. The opening of the formation is carried out in two stages, at the first of which pressure is created to destroy the membrane, but less than the pressure of hydraulic fracturing, and at the second stage the pressure of hydraulic fracturing, including acid, with the destruction of the cover of the cement stone and hydraulic fracturing. Hydraulic fracturing is created by means of a double packer with spaced cuffs and a perforated branch pipe between them, the cuffs of which ensure the creation of a sealed cavity in the area of the corresponding hydraulic fracturing coupling, which is lowered into the well to the installation site of the hydraulic fracturing coupling on the pipe column.  
     EFFECT: scope of application is expanding, including at high reservoir pressure and/or low permeability, reliability increases due to rupture of at least 95% of membranes, high-quality cementing of the casing string is provided.
