New reactive hole-transporting hydrazone and its adducts with diol and dithiol

New hole-transporting hydrazone with reactive vinyloxyethyl group and its glass forming adducts with 9-ethyl-3,6dihydroxymethylcarbazole and 4,4'-thiobisbenzenethiol have been synthesized. The thermal stability of the synthesized compounds has been estimated and their optical, photophysical and photoelectrical properties have been studied. The ionisation potential of 5.14 eV has been established for 2-vinyloxyethyloxy-4-diethylaminophenyl-1-carbaldehyde N,Ndipheny1hydrazone by electron photoemission technique. Hole mobilities exceeding 10(-5) cm/(V-s) at high electric fields have been observed by the time of flight technique in the 50 % solid solution of the hydrazone in bisphenol Z polycarbonateVytauto Didžiojo universitetasŽemės ūkio akademij

The influence of probiotic additives or multienzyme composition on blood biochemical parameters and milk quality of Lithuanian Black-and-White cattle

ABSTRACT The aim of the study was to determine the effect of Saccharomyces cerevisiae, multienzyme composition supplementation on milk yield, quality, blood biochemical parameters of Lithuanian-Black-and-White cows. For this reason 28 cows were divided into four groups (three experimental and one control) each with seven cows fed balanced ration (control group) and following experimental groups: addition of 40g supplement of live yeast with organic selenium (group A); 40g supplement of live yeast with aromatic additives (group B); and 0.2g supplement of multienzyme composition (group C) during a 90 days period. The study showed that milk yield was 2.64%, 1.75%, 1.4% higher in groups A, B, C respectively, comparing with the control group. The milk SCC in experimental groups were lower comparing to the control group. The percentage of milk fat was significantly higher in group A - 0.33%, B - 0.31% and C - 0.16% comparing with the control group. All used additives ensure positive dynamics of investigated biochemical parameters in cattle blood. The results indicated that probiotic additives and multienzyme composition supplementation to dairy cows increased cows productivity and milk fat as well. Probiotic additives supplementation decreased SCC values in milk

Methacryloyl functionalized hydrazones as hole-transporting materials for electrophotography

Syntheses and thermal, optical as well as photoelectrical properties of carbazolyl-, triphenylamino- and 2-hydroxy-4-diethylaminophenyl-based hydrazones with reactive methacryloyl groups have been reported. All the synthesized materials form glasses with glass transition temperatures ranging from 9 to 50 degrees C. They absorb electromagnetic radiation in the 250-440 nm range. Ionization potentials of the amorphous films of the synthesized materials, established by electron photoemission technique range from 5.20 to 5.71 eV. The lowest ionization potential and the best charge transport properties were observed for 2-(methacryloyl)oxy-4-diethylaminophenyl-1-carbaldehyde N,N-diphenylhydrazone. Time-of-flight hole mobilities in its 50% solid solution in bisphenol Z polycarbonate reach 10(-5) cm(2)/(V.s) at high electric fieldsVytauto Didžiojo universitetasŽemės ūkio akademij
