The thermal desorption behaviors of low-ring polycyclic aromatic hydrocarbons (PAHs), naphthalene (Nap) and acenaphthene (Acp), adsorbed by activated carbon (AC) were studied by the SETSYS Evolution 16 TGA in nitrogen atmosphere. The single and multiple scan methods were combined to obtain the thermal desorption react…
In this thesis I will give a formal definition of side effects. I will do so by modifying a system for modelling program instructions and program states, Quantified Dynamic Logic, to a system called DLAf (for Dynamic Logic with Assignments as Formulas), which in contrast to QDL allows assignments in formulas and makes…
W artykule przedstawiono opracowaną metodę wraz z wynikami badań napawania mikroplazmowego kompozytowych warstw Ni-WC na półki łopatek sprężarki ze stopu tytanu. Analizowano strukturę napoin, ze szczególnym uwzględnieniem rozkładu pierwiastków dla okolicy linii wtopienia warstwy kompozytowej w podłoże oraz granicy mię…
W artykule przedstawiono badania zautomatyzowanego procesu napawania produkcyjnego i naprawczego krawędzi przedmiotów metodami TIG i PTA z materiałem dodatkowym w postaci zimnego drutu. Określono wpływ sposobu podawania drutu położenia jego końcówki względem jeziorka ciekłego metalu na stabilność procesu oraz kształt…
The present study deals with the reduction of barium sulfate (Barite) to barium sulfide by use of carbon as the reduction agent. Pellets of barite ore containing about 95% BaSO4 has been reduced under different conditions of temperature, time, ore grain size and the type and grain size of the carbon materials. Graphit…
Badania uszkodzeń uchwytów klapy dużej biernej silnika wykazały, że naprawa tych elementów wymaga opracowania warunków technologicznych napawania automatycznego plazmowego PTA oraz napawania laserowego HPDL materiałami dodatkowymi zapewnia- jącymi zwiększoną odporność na zużycie ścierne metal-metal, w stosunku do mate…

This article presents a simple linear damage accumulation model that may have applicability for predicting damage from sustained winds in double-sided acrylic foam tape used to attach curtain wall glazing panels to buildings. The purpose of this model is to investigate the possible cumulative effects of years of wind-…
In this article we present a fabrication method for producing 15 nm wide 45 nm deep nanogrooves on the metal surface that provide for efficient light trapping. These grooves form a subwavelength grating that allows p-polarized light to efficiently cople to the surface plasmon polaritons modes inside the grooves produc…
Calmodulin (CaM) transduces the increase in cytosolic Ca(2+) concentrations by binding to and altering the activities of target proteins, thereby affecting the physiological responses to the vast array of stimuli. Here, we examined the purified recombinant proteins encoded by three Cam and eight Cam-like (CML) genes f…
The effect of oxygenate modifiers on the performance of Pt–Sn/γ–Al2O3 catalyst in dehydrogenation of propane was studied. Dehydrogenation reaction was carried out in a fixed-bed quartz reactor in the temperature range of 575–620 °C. Two types of oxygenate modifiers, namely water and methanol, were added to the feed. T…
β-Citrylglutamate (BCG), a compound present in adult testis and in the CNS during the pre- and perinatal periods is synthesized by an intracellular enzyme encoded by the RIMKLB gene and hydrolyzed by an as yet unidentified ectoenzyme. To identify β-citrylglutamate hydrolase, this enzyme was partially purified from mou…
Collagen VI is a ubiquitous extracellular matrix protein that assembles into beaded microfibrils that form networks linking cells to the matrix. Collagen VI microfibrils are typically formed from a heterotrimer of the α1, α2, and α3 chains. The α3 chain is distinct as it contains an extended N terminus with up to 10 c…
A best evidence topic was written according to a structured protocol. The question addressed was whether harvesting the saphenous vein (SV) as a conduit for coronary artery bypass grafting (CABG) using a no-touch technique would result in better patency rates. This technique involves the harvest of the SV with a pedic…
Bacterial chromosome replication is initiated by binding of DnaA to a DnaA-box cluster (DBC) within the replication origin (oriC). In Bacillus subtilis, six additional DBCs are found outside of oriC and some are known to be involved in transcriptional regulation of neighboring genes. A deletion mutant lacking the six…
In this study, the near band edge anisotropic optical properties of wurtz-stannite (WS) Cu2ZnGeS4 single crystals were characterized using polarization-dependent transmittance and electrolyte electroreflectance (EER) techniques. Single crystals of Cu2ZnGeS4 were grown by chemical vapor transport method using iodine as…
To study the effects of nano-TiO 2 particles on membrane performance and structure and to explore possible interactions between nano-TiO 2 particles and polymer, polymer/TiO 2 embedded hybrid membranes and neat polymer membranes were prepared using the phase inversion method. Poly(vinylidene difluoride) (PVDF), poly(v…
