Artificial neural network based fatigue life assessment of friction stir welding AA2024-T351 aluminum alloy and multi-objective optimization of welding parameters
PublikacjaIn this paper, the fracture behavior and fatigue crack growth rate of the 2024-T351 aluminum alloy has been investigated. At first, the 2024-T351 aluminum alloys have been welded using friction stir welding procedure and the fracture toughness and fatigue crack growth rate of the CT specimens have been studied experimentally based on ASTM standards. After that, in order to predict fatigue crack growth rate and fracture toughness,...

Qualitative changes in CEECs trade specialization (1995-2005) - the implications for economic growth process
PublikacjaCelem opracowania jest przedstawienie zmian jakościowych w strukturze eksportu w krajach Europy Środkowo-Wschodniej w latach 1995-2005. Jako miernik jakościowy eksportu wykorzystano indeks Hausmann et al (2007). Wyniki badań wskazują, różnice w relatywnych poziomach PKB per capita względem krajów UE-15 są znacznie większe niz różnice w jakościowej strukturze eksportu pomiędzy Nowymi Krajami Członkowskimi a krajami ''Pięnastki''....

SEI Growth and Depth Profiling on ZFO Electrodes by Soft X-Ray Absorption Spectroscopy
PublikacjaZnFe2O4 (ZFO) Li-ion batteries (LIBs) represent a reliable, affordable, and safe energy storage technology for use in portable application. However, current LIB active materials (graphite, lithium/transition metal spinel or layered oxides, olivine structures) can store only limited energy since they rely on insertion storage based on solid-state host-guest interactions. Moreover, performances and durability of the cells are strongly...

Phosphorylation of glucosamine-6-phosphate synthase is important but not essential for germination and mycelial growth of Candida albicans.
PublikacjaStosując mutagenezę ukierunkowaną dla genu gfa1 kodującego syntazę glukozamino-6-fosforanu Candida albicans otrzymano zmutowaną wersję GFA1S208A. Produkt zmutowanego genu, który utracił miejsce fosforylacji dla kinazy A, wykazywał wszystkie właściwości identyczne do dzikiego enzymu, jednakże nie był substratem dla kinazy. Brak fosforylacji syntazy glukozamino-6-fosforanu przez kinazęA prowadził do redukcji lecz nie eliminował...

Linkages between services and manufacturing as a new channel for GVC growth: evidence from CEE countries
PublikacjaThe aim of this paper is to use a panel Granger causality test to verify the hypothesis of the existence of a causal relationship between forward linkages from domestic services to manufacturing and a country’s participation and position in GVCs in selected central and eastern European economies – the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland and Slovakia – for the period 2000-2014. Our results show that the Baltic...

Opioid Growth Factor and its Derivatives as Potential Non-toxic Multifunctional Anticancer and Analgesic Compounds
PublikacjaIn this paper, we review the structure-activity relationship of OGF and its analogues. We highlight also OGF derivatives with analgesic, immunomodulatory activity and the ability to penetrate the blood-brain barrier and may be used as safe agents enhancing chemotherapy efficacy and improving quality of life in cancer patients. The reviewed papers indicate that Met-enkephalin and its analogues are interesting candidates for the...
