Abstract: FIELD: medicine.SUBSTANCE: declared invention refers to medicine, namely to surgery, and can be used for intraoperative identification of altered parathyroid glands (PTG). For this purpose, the patient is once administered 5-aminolevulinic acid in dose of 10 mg/kg of body weight not earlier than 120 minutes and not later than 720 minutes before the operation, which is carried out by irradiating an operating field with polarized blue light at wave length 395–405 nm for detecting fluorescence. If observing fluorescent formations in the area of irradiated tissues, the new growths are removed with their subsequent urgent histological examination. If observing the glandular epithelial hyperplasia, the unchanged portion of the parathyroid glands is re-implanted into the forearm muscle of the forearm.EFFECT: method enables increasing the surgical intervention effectiveness by 100 % probability of visualizing PTG tissue with reducing complications by single administration of the preparation in a small volume and broader possibility of surgical intervention due to a high time interval.1 cl, 2 ex, 3 dwg

Abstract: FIELD: investigation of earth surface. 
     SUBSTANCE: invention relates to investigation of earth surface and can be used in agriculture, in particular for rice growing. Method includes conversion of obtained image, calculation of areas of selected outlines. During the non-vegetation period using the navigation system on the map of the rice field, coordinates and numbers of sampling points of soil samples and measurements of groundwater level and mineralization are plotted. Then, soil reclamation state is quantitatively estimated by ground water level and mineralization, humus content and acid-alkaline soil properties; provision of hydrolyzable nitrogen, mobile potassium and mobile phosphorus; percentage content of soil aggregates in arable horizon; degree and type of soil salinity by assigning to each meliorative criterion from 1 to 5 points depending on degree of its influence on meliorative state of soil. Thereafter, meliorative condition of soil is estimated by total score of melioration criteria. Then, for each meliorative state of soil, a process map is developed with an optimum adaptive complex of technological operations. At the same time, meliorative criteria are additionally taken into account: humus resources in 0–100 cm layer; nitrogen enrichment with C:N; content of exchangeable magnesium in soil (MgO); content of sulphate (mobile) sulfur; degree of saturation with bases; total porosity; soil density; nitrification ability of soil at the beginning of sowing of winter and wintering crops; content of water-resistant aggregates > 0.25 mm in 0–30 cm layer at the beginning of the winter and wintering crops sowing; "Total effect" of toxic ions CO 3   2- , HCO 3   - , Cl - , SO 4   2- ; CO 2  emission rate in soil; content of microelements (Manganese (Mn), Copper (Cu), Zinc (Zn), Cobalt (Co), Molybdenum (Mo)). Then, ameliorative condition of soil is evaluated by total score of reclamation criteria, and with total score of 20–50, meliorative state of soil is considered to be good; 50–80 – satisfactory, 80–100 – unsatisfactory. 
     EFFECT: higher efficiency and quality of assessing agroresource state of soils.

Abstract: FIELD: pulse technology. 
     SUBSTANCE: method relates to the technology for detecting pulse signals the duration whereof is variable in a wide range and the carrier frequency, type and parameters of intra-pulse modulation are unknown. The method consists in amplitude detection of a mixture of the signal with noise, supply of an output signal of the amplitude detector to a set of independent parallel post-detector low-pass filters (LPF) with a consistently narrowing bandwidth, independent processing of the output signal of each LPF by a pulse signal detector using a comparison of the current value of the signal envelope with an adaptive or fixed detection threshold proportional to the noise power estimate. Low-frequency filtering of the output signal of the detector is used in the method in several independent parallel channels with post-detector low-frequency filters LPF with a consistently narrowing (e.g., by a given whole number of times) bandwidth. The detection threshold is decreased when the LPF bandwidth is narrowed, providing an increase in the probability of detecting a signal while maintaining the preset probability of a false alarm by reducing the dispersion of the detected noise leading to a reduction in the probability of exceeding the threshold by a noise spike. 
     EFFECT: creation of a method for detecting pulse signals with unknown parameters, insensitive to changes in the carrier frequency and the duration of the detected signals.
