The variety of body shape correction techniques based on liposuction and currently used in plastic surgery is largely due to the desire to achieve the greatest possible cosmetic effect and, at the same time, minimize the possible negative consequences of invasive intervention. The choice of a specific method depends on a number of factors, among which are the treatment plan agreed with the patient, the individual characteristics of the patient being operated on, the presence or absence of medical contraindications to the use of certain techniques, the qualifications of the personnel, the level of material equipment of the operating unit. Liposuction is the aspiration of fat from subcutaneous tissue. It can be used for aesthetic lipoplasty or combined with body contouring surgery. The article is of a review nature and contains modern data on the medical effects of liposuction, VASER (Vibration Amplification of Sound Energy at Resonance) and PAL (Power Assisted Liposuction) techniques, and possible complications after liposuction.

A new means of measuring the thermal and heating engineering parameters of materials and constructions, employed in monitoring and diagnostics, is proposed. Some problems that arise during measurements are also considered.

Metrological equipment designed for calibrating contact thermometers at temperatures ranging from –40 to +40 °C (cryostat KR-40-2) and from –80 to +40 °C (cryostat KR-80) is described.

The design of an automatic resonance-frequency gage (ARFG) has been developed and a property has been produced. The instrument can be used for measuring the frequencies and for determining, on the basis of correlations, other parameters of the product concerned. The precision (±1.5%) and reliability of these measurements are higher than can be achieved in nonautomated testing. The speed and simplicity of the frequency-measuring process makes possible the continuous monitoring of the phase conversions in refractories during heating or cooling. The ARFG can be used for flaw and crack detection and for piece-by-piece quality control in automatic production lines for special-purpose refractories.
