Abstract: FIELD: biotechnology.SUBSTANCE: invention represents a diagnostic technique for predisposition to renal cell carcinoma based on PCR-RFLP, which consists in DNA extraction from pre-selected biological material of patients with PCR reaction, using primers GCAGGCCTCTCTGTCTGAAC (SEQ ID NO: 2) and GATGACATGTGGGTGGTTGA (SEQ ID NO: 2), as well as the restriction analysis of the obtained amplicon. Restriction enzyme Tsel is used for restriction of the amplicon. Restriction enzyme forms unique restriction fragments in the presence of mutations and normal (31 bp, 61 bp and 104 bp in norm; 92 bp and 104 bp in the presence of a mutation). If observing a mutation during the reaction, a person in the European population has predisposition to renal cell carcinoma.EFFECT: invention enables detecting predispositions to renal cell carcinoma in a human from the European population for 4½–6 hours (depending on the selected DNA extraction method) without the need to sequencing DNA samples.1 cl

According to the target hitting method the guided missile equipped with the noncontact target sensor- NTS, the missile is launched. After launching of controlled missile with the help of NTS begin to record and record data on background-target situation. When a controlled missile is received at a pre-meeting point, recorded data on the background-target situation are analysed for a time interval. Analysis results form the threshold of operation of the NTS and begin to continuously compare the level of the signal reflected from the target with it. Subject to exceeding the threshold of operation of NTS by a given value, a command is issued to blast the warhead of the guided missile. Threshold of operation of the NTS and the value of exceeding the actuation threshold are determined from analytical expressions. 
     EFFECT: technical result is increase in target hitting efficiency by avoiding false triggering.
