PPA在LLDPE/LDPE农膜加工中的应用

本工作以LLDPE／LDPE为基料，添加氟弹性体加工改性剂DynamarPPA，采用LDPE挤出机加工农膜。结果表明，挤出机加工LLDPE的能力大幅度地提高，使共混物中LLDPE含量从原来的40％增加到80％，薄膜的物理机械性质亦有明显改善，而主机电流和挤出量未见变化。在添加无滴剂母料条件下，可加工LLDPE总含量达95％的无滴膜，且该膜的力学性质和光学性质均住。

LLDPE/LDPE薄膜加工改性剂PPA

以LLDPE/LDPE共混树脂为基料,添加加工改性剂氟弹性体PPA,采用挤出吹塑成型加工薄膜制品。以LLDPE/LDPE质量比为1/2作空白样。按每克试样总量中含500μg PPA的比例添加PPA,当共混物中LLDPE含量为1/3时,挤出机电流下降,薄膜的透光率增加,雾度降低;LLDPE含量为60％时,挤出机电流未变而产量提高,薄膜的透光率和雾度变化不大;继续增加LLDPE比例时,挤出机电流和雾度增加。薄膜的拉伸性能随LLDPE比例增大显著提高,且纵横向的取向度变小。

Gry fabularne jako technika autonomizująca studenta

Publikacja (…) jest zbiorem tekstów poświęconych zagadnieniu autonomii w dydaktyce języków obcych. Teksty te – w obecnej postaci artykułów – stanowią zapis referatów wygłoszonych na konferencji poświęconej temu w��aśnie, niezwykle istotnemu dla nowoczesnej dydaktyki zagadnieniu. Konferencje tego typu nigdy dotąd w Polsce się nie odbywały. Jest to więc novum na naszym terenie i wielki tytuł do chwały dla uczelni, która podjęła się organizacji takiego wydarzenia i publikacji artykułów opracowanych na podstawie wygłoszonych tam referatów. Dlatego publikację uważam za niezwykle ważną i potrzebną. (z recenzji wydawniczej Prof. dr hab. Hanny Komorowskiej)

Investigation of global regulators influencing styrene metabolism and bioplastic synthesis in Pseudomonas putida CA-3

The genetics and biochemistry involved in the biodegradation of styrene and the production of polyhydroxyalkanoates in Pseudomonas putida CA-3 have been well characterised to date. Knowledge of the role played by global regulators in controlling these pathways currently represents a critical knowledge gap in this area. Here we report on our efforts to identify such regulators using mini-Tn5 transposon mutagenesis of the P. putida CA-3 genome. The library generated was subjected to phenotypic screening to identify mutants exhibiting a reduced sensitivity to the effects of carbon catabolite repression of aromatic pathway activity. Our efforts identified a clpX disrupted mutant which exhibited wild-type levels of growth on styrene but significantly reduced growth on phenylacetic acid. RT-PCR analysis of key PACoA catabolon genes necessary for phenylacetic acid metabolism, and SDS-PAGE protein profile analyses suggest that no direct alteration of PACoA pathway transcriptional or translational activity was involved. The influence of global regulators affecting the accumulation of PHAs in P. putida CA-3 was also studied. Phenotypic screening of the mini-Tn5 library revealed a gacS sensor kinase gene disruption resulting in the loss of PHA accumulation capacity in P. putida CA-3. Subsequent SDS-PAGE protein analyses of the wild type and gacS mutant strains identified post-transcriptional control of phaC1 synthase as a key point of control of PHA synthesis in P. putida CA-3. Disruption of the gacS gene in another PHA accumulating organism, P. putida S12, also demonstrated a reduction of PHA accumulation capacity. PHA accumulation was observed to be disrupted in the CA-3 gacS mutant under phosphorus limited growth conditions. Over-expression studies in both wild type CA-3 and gacS mutant demonstrated that rsmY over-expression in gacS disrupted P. putida CA-3 is insufficient to restore PHA accumulation in the cell however in wild type cells, over-expression of rsmY results in an altered PHA monomer compositions.
