Development of modification technology of wood raw material in production of solid biofuel

Studies have shown that the mechanical properties of the pellets produced from hardwoods yield pellets traditionally used pine. In order to improve their original wood raw material modified by the addition of protein nature (albumin, casein , gelatin) and starch (potato starch and maize, starch syrup) by spraying through nozzles in the screw feeder directly before granulation. To increase the strength of pellets application proteinaceous adhesives has proved more effective than the starch paste. Albumin as presented in this particular interest. To carry out industrial testing technology was developed modifications of chopped wood with its use in the production of pellets. The tests samples of modified wood pellets showed full compliance with them as a group 1 (in STB 2027). Humidity pellets was 10%, ash content – 0.7%, the wood dust abrasion – 0.8%; calorific value – 17,640 kJ/kg

Restoration of the Genus <i>Paraunisaccoides</i> Martin, 1973 (Digenea: Haploporidae) and Description of <i>P. elegans</i> n. sp. and <i>Unisaccus halongi</i> n. sp. from Mugilid Fish in Vietnam

We restore the genus Paraunisaccoides (Haploporidae), synonymised earlier with the genus Skrjabinolecithum. Adult worms, detected in Vietnamese mullet fish, were highly similar to trematodes described as P. lobolecithum via digestive and genital system structures and relative organ arrangement. Differences are expressed as absence and presence of pads on the hermaphrodite duct, respectively, and the disjunction of some metric parameter values, namely body, ovary and eggs. Ribosomal DNA sequences, based on the phylogenetic analysis of Haploporidae, indicates that new worms represent a sister clade to Unisaccus tonkini. Genetic divergence between new worms and Skrjabinolecithum species can be interpreted as intergeneric. Based on morphological and molecular data, we recognise Paraunisaccoides as a valid genus within Waretrematinae and worms from Vietnam as a new species of this genus, P. elegans n. sp. Other worms detected in Vietnamese mugilids are morphologically similar to representatives of Paraunisaccoides и Skrjabinolecithum. However, molecular-based phylogenetic analysis showed that these trematodes are closely related to Unisaccus tonkini; the genetic divergence between them is at the interspecific level, despite considerable differences in vitellarium structure as intergeneric character. Accepting the priority of molecular results, we include these new worms into the genus Unisaccus as new species, Unisaccus halongi n. sp
