Evaluation of mercury content in combustible tobacco products by employing cold vapor atomic absorption spectroscopy and considering the moisture content: a comprehensive study
PublikacjaPlants are mainly made up of water, which constitutes between 80 and 90% of their weight. Moisture factor comes across as one of the most important in tobacco products. Rapid determination of moisture content in tobacco products comes at neces- sity in any tobacco management plants (before and after production). Therefore, the concern has been raised in this study to evaluate the moisture content in four kinds of combustible tobacco...

A new cold-adapted beta-D-galactosidase from the Antarctic Arthrobacter sp. 32c - gene cloning, overexpression, purification and properties
PublikacjaThe development of a new cold-active β-D-galactosidases and microorganisms that efficiently ferment lactose is of high biotechnological interest, particularly for lactose removal in milk and dairy products at low temperatures and for cheese whey bioremediation processes with simultaneous bio-ethanol production. In this article, we present a new β-D-galactosidase as a candidate to be applied in the above mentioned biotechnological...

Pomiar zakłóceń elektrycznych i hałasu okrętowego systemu napędowego z przemiennikami częstotliwości.
PublikacjaW ostatnich latach coraz większa liczba systemów napędowych z silnikami asynchronicznymi klatkowymi zasilanymi z przemienników częstotliwości instalowana jest na statkach morskich. Wadą przemienników częstotliwości są generowane przez nie zakłócenia elektromagnetyczne o szerokim widmie częstotliwościowym, które przyczyniają się do znaczącego przyrostu hałasu emitowanego przez systemy napędowe. Przedstawiono cyfrowy system pomiarowy,...

Failure of cold-formed beam: How does residual stress affect stability?
PublikacjaIn machine industry, stresses are often calculated using simple linear FEM analysis. Occasional failures of elements designed in such a way require recomputation by means of more sophisticated methods, eg. including plasticity and non-linear effects. It usually leads to investigation of failure causes and improvement of an element in order to prevent its unwanted behavior in the future. The study presents the case where both linear...

THE EFFECT OF WET UNDERWATER WELDING ON COLD CRACKING SUSCEPTIBILITY OF DUPLEX STAINLESS STEEL
PublikacjaABSTRACT The present work was conducted to assess the weldability of duplex stainless steel in underwater conditions. Metal manual arc welding (MMA) with the use of coated electrodes was used in the investigations. Tekken weldability tests were performed underwater at 0.5 m depth and in the air. Nondestructive tests, metallographic examinations of welds, ferrite content assessment in microstructure and hardness test were performed....

Chapter 13 : The influence of dispersion phase on composite coating properties after cold working
PublikacjaW pracy określono wpływ fazy dyspersyjnej Al2O3 na wybrane potencjalne właściwości powłok kompozytowych o osnowie niklowej. Powłoki Ni-Al-Al2O3 zostały nałożone na próbki stalowe przy użyciu technologii poddźwiękowego płomieniowego natryskiwania cieplnego. Następnie poddane zostały obróbce plastycznej na zimno i na gorąco poprzez walcowanie, a także prasowania na zimno na prasie hydraulicznej. Obróbka plastyczna jest metodą alternatywną...

Antarctic marine bacterium Pseudoalteromonas sp. 22b as a source of cold adapted á-galaktosidase.
PublikacjaAntarktyczny morski szczep Pseudoalteromonas sp. 22b. jest źródłem wewnątrzkomórkowej beta-galaktozy. Enzym ten wykazuje wysoką aktywność hydrolizy laktozy w zakresie temperatur od 0 do 20 st. C oraz pH 6,0-8,0. W niniejszej pracy opisano metodykę uzyskania homogennego preparatu tego enzymu, oraz pełną charakterystykę jego własności enzymatycznych i kinetycznych.

Mass spectrometric identification of 13C-Labeled metaboloites during anaerobic propanoic acid oxidation
PublikacjaBiowaste digestion is a possibility to gain biogas as a renewable fuel source. However, the anaerobic food chain may be disrupted by, e.g., substrate overload or by inhibitors, leading to the accumulation of volatile fatty acids (VFAs), predominantly of propanoic acid (PA). VFA Accumulation may cause a rapid pH decrease, less biogas production, or even a total inhibition. To maintain high biogas productivity or to prevent a collapse...

Interspecies distances between propionic acid degraders and methanogens in syntrophic consortia for optimal hydrogen transfer
PublikacjaA mixed culture from an anaerobic biowaste digester was enriched on propionate and used to investigate interspecies hydrogen transfer in dependence of spatial distances between propionate degraders and methanogens. From 20.3 mM propionate, 20.8 mM acetate and 15.5 mM methane were formed. Maximum specific propionate oxidation and methane formation rates were 49 and 23 mmol mg−1day−1, respectively. Propionate oxidation was inhibited by...

A New Expression System Based on Psychrotolerant Debaryomyces macquariensis Yeast and Its Application to the Production of Cold-Active β-D-Galactosidase from Paracoccus sp. 32d
PublikacjaYeasts provide attractive host/vector systems for heterologous gene expression. The currently used yeast-based expression platforms include mesophilic and thermotolerant species. A eukaryotic expression system working at low temperatures could be particularly useful for the production of thermolabile proteins and proteins that tend to form insoluble aggregates. For this purpose, an expression system based on an Antarctic psychrotolerant...
