Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to ophthalmology, and can be used for selecting laser exposure parameters in treating far-reaching and terminal refractory glaucoma. Ciliary body thickness in mm is measured by ultrasonic biomicroscopy. Laser applicants are applied at equal distance from each other by diode laser by contact-transscleral method in continuous mode with wavelength of 810 nm. Applications are applied at 2–3 mm from the limb along circumference by 360 degrees, avoiding positions at 3 and 9 o'clock. If the ciliary body thickness is 0.4 mm or less, the power of one laser exposure pulse is 0.8–1.2 W. If the ciliary body thickness is more than 0.4 mm and less than 0.6 mm, the power of one laser exposure pulse is greater than 1.2 W and less than 1.8 W. If the ciliary body thickness is 0.6 mm or more, the power of one laser exposure pulse is 1.8–2.2 W. Number of applicants at all thicknesses of ciliary body 18–22. Exposure time 4 sec. 
     EFFECT: method provides stable normalization of intraocular pressure in postoperative period, preservation of residual visual functions in patients with far-away refractory glaucoma, withdrawal of pain syndrome in patients with terminal painful glaucoma, reduced risk of postoperative complications, and also increases convenience of surgeon due to selection of parameters of laser exposure depending on thickness of ciliary body.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to oncology; it can be used to predict the degree of risk of developing hematogenous metastases in invasive carcinoma of a non-specific type of mammary gland based on the assessment of the expression of LIMCH1 protein. A study of patient’s tumor tissue and the subsequent calculation of a diagnostic indicator are carried out. Using immunohistochemical studies, a value of the cytoplasmic expression of LIMCH1 protein in tumor cells is determined and evaluated in points. If the number of cells with cytoplasmic expression of LIMCH1 protein is more than or equal to 1, the value is estimated at 2 points. If the number of cells with cytoplasmic expression of LIMCH1 protein is less than 1, the value is estimated at 1 point. A value of a regression equation Y is calculated using the formula Y=-4.39+3.04·X1, where -4.39 is a value of a regression coefficient of a free term; X1 is the value of the cytoplasmic expression of LIMCH1 protein in tumor cells of invasive carcinoma of mammary gland in points; 3.04 is the value of the regression coefficient of this trait. Next, a value of the probability of developing hematogenous metastases P is determined using the formula P=e Y /(1+e Y ), where e is mathematical constant equal to 2.72. If P is more than or equal to 50%, a high risk is determined, and if P is less than 50%, a low risk of developing hematogenous metastases is determined.  
     EFFECT: method makes it possible to predict the level of risk of developing hematogenous metastases in invasive carcinoma of a non-specific type of mammary gland by determining the cytoplasmic expression of LIMCH1 protein in tumor cells and using a mathematical model to calculate the probability of developing hematogenous metastases, which makes it possible to simplify and increase the accuracy and informativeness of the method.

Abstract: Изобретение относится к железнодорожному транспорту, в частности к средствам перевозки вязких при охлаждении нефтепродуктов. Цистерна для перевозки масел, мазутов и других вязких нефтепродуктов при низких температурах включает установленный на транспортных тележках котел (1) с верхним наливным люком, нижним сливным прибором, парообогревательный кожух (4), закрепленный на нижней половине котла. На штанге над седлом клапана сливного прибора установлен изолированный сосуд, заполненный теплопоглощающим материалом. Верхняя половина котла цистерны над парообогревательным кожухом покрыта теплоизолирующим материалом. Внутри парообогревательного кожуха под углом 10 градусов устанавливается П-образная паровая рубашка (19), состоящая из трех рядов труб диаметром 2-3 см, размещенных параллельно друг другу вдоль сторон котла цистерны. Трубы жестко крепятся к держателям, которые привариваются к котлу. На конце паропровода выхода пара рубашки устанавливается участок трубопровода, который соединяется с входным патрубком кожуха. Предварительный прогрев котла цистерны на месте выгрузки паровой рубашкой до положительных температур не допускает температурных напряжений сварных швов и металла котла, с дальнейшим подогревом нефтепродукта пароводяной смесью и теплом от паровой рубашки в парообогревательном кожухе. Изобретение обеспечивает сохранение высокой температуры и текучести перевозимого нефтепродукта, сокращает время его выгрузки и снижает затраты тепловой энергии на подогрев нефтепродукта при низких температурах. 5 з.п. ф-лы, 5 ил.

Abstract: FIELD: electrical engineering. 
     SUBSTANCE: invention relates to electrical engineering and can be used to diagnose the state and control the drive electromagnets (EM) of valves and switching devices. Determination of the current value of the current through the winding and the sign of the rate of its change is carried out after processing the result of measuring the current by a low-pass filter at the stage of releasing the EM after removing the voltage from its winding. Moreover, from the moment of time when the current value of the current through the winding begins to increase, corresponding to the beginning of the armature movement when released, and until the moment characterizing the end of the armature movement, the current value of the position of the armature of the EM is determined at each moment of time of its movement when released by the current value of the current through the winding. The magnitude of the local maximum current is then determined at the time when the current value of the current through the winding begins to decrease after its increase during release. This moment in time of reaching the local maximum of the current is considered the end of the armature movement, and a sign is formed indicating the transition of the electromagnet armature to the final position when released. Also proposed is a functional diagram of a device for determining the position of an EM armature, focused on using the PIC16F1778 microcontroller as a control element that ensures the implementation of the operations of the claimed method. The performance and efficiency of the proposed technical solution has been confirmed experimentally. 
     EFFECT: simplified and expanded functionality.
