The article provides data on the determination of morphological features and bioecological features of the development of a particularly dangerous object Tuta absoluta (Povlony) in laboratory and greenhouse conditions. In greenhouses and laboratory conditions, the imago begins to actively mate 3-4 hours before sunrise. In laboratory conditions, females lay eggs on the surface of leaves (35%), below (45%), stems (15%), fruit leaves (5%), but the fruit was not laid. After hatching from the eggs, the larvae chew through the entrance to the mesoderm of the leaf and penetrate for 5 minutes. The Larva Of T. absoluta is almost cylindrical in shape, with a distinct head, three pairs of pectoral legs, and five pairs of ventral pseudopods. After completing all five stages of development, the larvae emerge from the mine, and sometimes pupate there. Before pupation, the larva changes its color from dark green to light green. The pupa of the tomato moth, as in other Lepidoptera, is of the “obtecto " type, that is, with the future appendages of adults. It has the shape of a cone 4.5-5 mm long and 1.3-1.5 mm wide, greenish in color, turning to a more intense brown, and at the end of development becomes brown. In the population, females predominate over males. At a temperature of 15°C and 33°C the ratio of female to female life expectancy varies. The higher the air temperature, the more females predominate in the population.

The purpose of this paper was presentation of the value of cores electrification during their flow in the modified Wurster apparatus, applied for dry encapsulation of pharmaceutical materials. Previous works of the authors dealt with vulnerability of the particles of different diameter, produced by SYNTAPHARM (Cellets 1000, 700 and 100) on electrification in laboratory conditions. The presented work gives the results of examination on particles electrification in real conditions of their stable circulation in a column. The measurement system, that was applied, allowed determination of electrification potential and electrification current. Those quantities, which are the measures of charge accumulation on cores were determined for several particles (Cellets 1000, 700 and 500) with the different humidity, for different mass of the bed and spouting gas velocities.

The Impact

AbstractThe objective of the paper was to analyse the use of the designed photobioreactor for freshwater microalgae cultivation in the controlled laboratory conditions. The work covered the design and construction of photobioreactors (PBR) and setting up comparative cultivations of freshwater microalgae chlorelli vulgaris along with determination of the biomass growth intensity for a varied amount of supplied culture medium. It was found out that the constructed PBR may be used for microalgae cultivation in the controlled conditions. The impact of the culture medium amount on the growth of chlorelli vulgaris was proved. As a result of the increase of culture medium concentration to 30.1-120.4 ml·l−1 of water, dry mass in photobioreactorsincreased respectively from 1.33 g·dm−3 to 4.68 g·dm−3.
