Divination from chips: monitoring of the sawing process with chip geometry analyzes
PublicationWióry (trociny) są niechcianym produktem towarzyszącym procesowi przecinania. Jednakże, niosą one w sobie wiele informacji świadczących o przebiegu procesu obróbki. Metoda oceny składu procentowego wiórów - ich frakcji - jest prosta lecz ma szereg ważnych ograniczeń. W pracy zaprezentowano nowy alternatywny sposób pomiaru geometrii wiórów. Przedstawiono wyniki dla skrawania drewna mrożonego i nie mrożonego. Wyniki uzyskane ta metodą...

Hoarfrost and rime chemistry in Poland - An introductory analysis from metrological perspective
PublicationW publikacji przedstawiono wyniki badań poziomów stężeń składników śladowych obecnych w próbkach osadów atmosferycznych (szronu i sadzi) zebranych na terenach wyraźnie różniących się pod względem położenia geograficznego jak również poziomem antropopresji. Zbadano wpływ czynników meteorologicznych tj. rodzaj mas powietrza, typ pola barycznego na chemizm tych form mokrej depozycji. Porównano skład chemiczny różnych form osadów atmosferycznych...

Recovery and re-use of photovoltaic solar cells from crystalline silicon
PublicationCrystalline silicon-type PV modules consist, in order of mass, of glass, an aluminium frame, an EVA coating, solar cells, a terminal box, back film and tapping screws. From the economic point of view, pure silicon, recoverable from spent cells, is the most important material owing to its cost and shortage. For crystalline, silicon-based PV cells, the following chemical treatments were performed: removal of the metal coating, followed...

Comparison of different extraction techniques of polychlorinated biphenyls from sediments samples.
PublicationIn this work, problems that may occur during determination of trace levels of polychlorinated biphenyls in sediment samples are described. Main error sources are connected with extraction of analytes prior to final determination. During model studies, polychlorinated biphenyls have been extracted from sedimentreference material (METRANAL 2) with the use of different solvents (dichloromethane, hexsane, and toluene); the process...

General scheme for construction of scalar separability criteria from positive maps
PublicationStandardowe nierówności entropijne są znanym narzędziem do detekcji splątania dwupodukładowych stanów kwantowych. W pracy podano metodę wyprowadzania nierówności przypominających standardowe nierówności entropijne z dowolnych odwzorowań dodatnich. Ponadto, przebadano nierówności w przypadku kilku znanych z literatury odwzorowań dodatnich.

Typing of Candida isolates from patients with invasive infection and concomitant colonization
PublicationWe investigated the relationship between colonizing and invasive isolates from patients with candidaemia. Molecular typing was performed using random amplification of polymorphic DNA (RAPD) and multilocus sequence typing (MLST). We found MLST to be sufficient for typing Candida isolates, and that surveillance cultures are helpful in predicting concomitant invasive isolates, but not necessarily the pathogen involved in subsequent...

Discovering patterns of Web Page Visits from Associaton Rules Viewpoint
PublicationThe popularity of the Internet results from the almost unlimited resources of information stored in it. At the same time, Internet portals have become a widespread source of information and note very large number of visits. The list of web pages opened by users is stored in web servers' log files. Extraction of knowledge on the navigation paths of users has become carefully analyzed problem. Currently, there are a number of algorithms...

Antioxidant and antimicrobial activity of fermented beverages obtained from fruit pomace
PublicationFruit pomace should not be considered as a waste product but as a by-product as it contains a lot of valuable components such as dietary fiber, bioactive compounds and a source of nutrients. The reasonable way to utilize these by-products, both fresh or dried, could be the fermentation of its extracts, leading to beverages with functional properties. In our research, we checked the possibility of using chokeberry, apple and...

Entropy of water calculated from harmonic approximation: estimation of the accuracy of method
PublicationSome molecular dynamics simulations were performed for liquid TIP4P and SPC water at a constant density (1.00 g/cm(3)) and within the temperature range of 5-90 degrees C. By using harmonic approximation, both the entropy of water S-H and the specific heat c(v) were calculated, and the results were compared to literature data. It was found that harmonic approximation overestimates absolute entropy of TIP4P water by 5.6 J/mol K (similar...

Studies on removal of hydrophobic organics from contaminated soil by washing process
PublicationZbadano efektywność wymywania NAPL ze złoża piaskowego za pomocą roztworów dwóch niejonowych surfaktantów: polioksyetylenowanego alkoholu tłuszczowego (Rokanol NL6) oraz alkiloglukozydu (Triton BG10). Jako NAPL zastosowano dwa węglowodory - dodekan i heksadekan. Oba surfaktanty były relatywnie efektywne w usuwaniu dodekanu. Ze wzrostem stężenia surfaktantu obserwowano wzrost efektywności wymywania dodekanu, jednakże Rokanol NL6...
