TRNA-Leu (UUR) gene haplotypes observed in canine mammary gland tumours and its deleterious effect assessment according to the comparative analysis with TRNL1 human gene
Open Research DataThe aetiology and pathogenesis of many canine tumours are likely to be similar to cancers found in humans. This study aimed to present a plausible link between changes in tRNA-Leu (UUR) gene and the carcinogenesis process in dogs with mammary gland tumours. The whole mitochondrial DNA (mtDNA) isolated from blood and tumour tissues of 13 dogs with malig-nant...

Creep rupture study of dissimilar welded joints of P92 and 304L steels
PublicationThe present work investigates the high-temperature tensile and creep properties of the dissimilar metal weld joints of 304L austenitic stainless steel (SS) and P92 creep strength-enhanced ferritic-martensitic (CSEF/M) steel under diferent testing condition. Thermanit MTS 616 fller rod (P92 fller) and the multi-pass tungsten inert gas (TIG) welding process were used to create the dissimilar weld connection. The ultimate tensile...

Molecular identification and genotyping of Staphylococci: genus, species, strains, colnes, lineages, and interspecies exchanges
PublicationStaphylococci are increasingly recognized as etiological agents of many opportunistic human and animal infections, emphasizing the need for a rapid and accurate identification, even to a genotypical level of these bacteria. In the recent years, there has been a significant progress in typing and phylogenetic study of Staphylococcus species. Here, we describe molecular methods used in taxonomy as well as staphylococci characterization....

Experimental verification of natural convective heat transfer phenomenon from isothermal cuboids
PublicationArtykuł przedstawia wyniki badań eksperymentalnych konwekcyjnej wymiany ciepła od powierzchni izotermicznego prostopadłościanu o stosunkowo dużych rozmiarach (t.j. 1.5 m x1 m x 0.5 m). Celem tych badań było otrzymanie wyników, które można by porównać z otrzymanymi dla obiektu w mniejszej skali i prezentowano we wcześniejszych doniesieniach (Int. J. Heat Mass Transfer 46 (2003) 2169-2178). Rozwiązanie eksperymentalne przeprowadzono...

The influence of plastic deformation on the magnetoelastic properties of the CSN12021 grade steel
PublicationWłasności magnetosprężyste materiałów są silnie modyfikowane przez zmiany struktury dyslokacyjnej, które są wynikiem procesów deformacji plastycznej. Zmiany te mogą być wykorzystane jako podstawa do opracowania metody nieniszczącej oceny stopnia deformacji materiału.Jak dotychczas zaproponowane zostały różne metody, oparte na pomiarach pętli histerezy magnetycznej czy też natężenia magnetycznego efektu Barkhausena. Artykuł porównuje...

Nieliniowy model matematyczny transformatora trójfazowego = Non-linear mathematical model of a three-phase transformer
PublicationPrzedstawiono model transformatora trójfazowego o rdzeniu trójkolumnowym, który zawiera układ rów-nań opisujących obwód magnetyczny oraz oddzielnie układ równań obwodu elektrycznego. Wydzielenie re-luktancji elementów rdzenia umożliwia uwzględnienie zmian względnej przenikalności magnetycznej w funkcji bieżącej wartości strumienia w rdzeniu. Re-luktancje odpowiadające strumieniom rozproszenia obliczono wg zasad klasycznych. Funkcję...

Minimal parameter implicit solvent model for ab initioelectronic-structure calculations
PublicationAbstract - We present an implicit solvent model for ab initio electronic-structure calculations which is fully self-consistent and is based on direct solution of the nonhomogeneous Poisson equation. The solute cavity is naturally defined in terms of an isosurface of the electronic density according to the formula of Fattebert and Gygi (J. Comput. Chem., 23 (2002) 662). While this model depends on only two parameters, we demonstrate...

The effect of UV-C irradiation on lipids and selected biologically active compounds in human milk
PublicationThe effect of UV-C irradiation of human milk on lipid oxidation, content of antioxidants (vitamin C and catalase, CAT) and bactericidal compounds (lysozyme), as well as the total antioxidant capacity (TAC), of the breast milk was investigated. In parallel, the extent of inactivation of some bacteria was also determined. UV-C at doses from 85 to 740 J L−1 caused total inactivation of Escherichia coli and Staphylococcus aureus, but...

Positron scattering on molecular hydrogen: Analysis of experimental and theoretical uncertainties
PublicationExperiments performed in recent years on positron scattering from molecular hydrogen indicated a rise of the total cross section in the limit of zero energy, but essentially disagree on the amplitude of this rise. Mitroy and collaborators [J.-Y. Zhang et al., Phys. Rev. Lett. 103, 223202 (2009)] predicted a scattering length somewhat different from values deduced experimentally. Using a Markov chain Monte Carlo modified effective...

Exemplary AFM application in cosmetology
Open Research DataAtomic force microscopy can be used in the diagnosis of the condition of human tissues such as skin, nails and hair. This is obviously related to the use of a variety of cosmetic products and can be understood as an attempt to assess their long-term impact on human appearance and health. An example may be the studies presented in [1] indicating the...

Results of the effect of mixtures of ketoprofen with three cations on the germination of Sorghum bicolor (sorghum) seeds
Open Research DataThe research data includes an attempt to verify whether the addition of cations (sodium, ammonium and potassium) at levels found in the environment would affect the toxicity of pharmaceuticals to Sorghum Bicolor grain. Ion concentrations were selected based on studies of water samples collected in water bodies receiving wastewater from wastewater treatment...

Changes in gene methylation patterns in neonatal murine hearts: Implications for the regenerative potential
PublicationBackground The neonatal murine heart is able to regenerate after severe injury; this capacity however, quickly diminishes and it is lost within the first week of life. DNA methylation is an epigenetic mechanism which plays a crucial role in development and gene expression regulation. Under investigation here are the changes in DNA methylation and gene expression patterns which accompany the loss of regenerative potential. Results The...

Seabed characterisation using spectral moments of the echo signal
PublicationZbadano użyteczność zastosowania momentów spektralnych obwiedni echa w rozpoznawaniu i klasyfikacji dna morskiego. Przeprowadzono obliczenia momentów spektralnych dla około 15000 ech od dna zarejestrowanych w rejonie Bałtyku Południowego i potwierdzono tezę, że wartości tych momentów skorelowane są silnie z typem dna i rodzajem osadów.

The use of chain extenders as processing aids in the valorization of single-use polylactide (PLA) products by rotomolding
PublicationBiodegradable plastics in single-use products have increased in popularity as a way to reduce the negative environmental impact of conventional plastics and meet the tightening law regulations. However, their recyclability needs to be assessed, as the environmental behavior of single-use plastics, even if compostable, is not negligible. Polylactide (PLA) is susceptible to thermal, oxidative, hydrolytic, and mechanical degradation...

Metylotransferazy ssaków – inhibitory i aktywatory
PublicationWśród metylotransferaz ssaków możemy wyróżnić metylotransferazy histonowe oraz metylotransferazy DNA. Metylacja DNA w obrębie wysp CpG oraz metylacja histonów wpływają na poziom ekspresji genów w komórkach ssaczych. Dodatkowo dzięki metylacji zapewniana jest stabilność i integralność genomu ludzkiego. Metylotransferazy DNA, będące głównym tematem tego artykułu, są często przedmiotem badań, gdyż nieprawidłowa metylacja DNA jest...
