Abstract: FIELD: measuring. 
     SUBSTANCE: invention relates to the field of measuring equipment, namely to registration of parameters of the dynamics of impact-induced "dusting" from the inner surface of a spherical liner during assessment of the state/behaviour thereof under load. The apparatus for recording the dynamics of the condition of an impact-loaded spherical liner surface includes a hemispherical charge of an explosive substance (ES) placed on the base and sensors recording the movement of the liner installed in the charge cavity and configured to form a sealed volume connected with the gas inlet system. The liner is installed adjacent to the charge of the ES. A sealed volume is formed between the liner and a hemispherical bracket fixed on the base with a curvature facing the liner. The gas inlet system is connected with a pump to create underpressure. Additionally, sensors based on different physical principles are installed to measure the speed, density distribution and mass of the dust flow escaping from the liner surface, namely collimators, piezoelectric sensors, collimators with indicator screens, fixed on the bracket and placed in a sealed volume at different distances from the liner surface. 
     EFFECT: increased information content of the experimental results is provided by directly determining the quantitative characteristics of the process of impact-induced "dusting".

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to veterinary neonatology, and can be used to assess the functional reserves of a newborn animal. A study of the enzymatic activity of the tissue is carried out. The assessment of functional reserves is carried out for newborn piglets, for which an enzyme test is performed to determine the activity of carboxypeptidase in the placenta. The reduced nicotinamide adenine dinucleotide phosphate is used as a coenzyme, sodium citrate serves as a substrate. The activity is expressed in arbitrary units - the number of micrograms of reduced neotetrazolium per 1 mg of dry tissue of the placenta in 30 minutes. When the enzyme activity is below 4.0 units of animals are referred to the group of individuals with high functional reserves. When the enzyme activity is more than 4.0 - to animals with low functional reserves. 
     EFFECT: invention provides an opportunity to increase the reliability of laboratory research (non-invasive prenatal screening of newborn animals) by identifying the state of increased enzymatic activity of the placental tissue, which makes it possible to form a group of animals with a high risk of impaired functional reserves.
