Production of self-compacting concrete using limestone powder
PublikacjaAlthough there are visible signs of its gradual acceptance in North Africa through its limited use in construction, Libya has yet to explore the feasibility and applicability of self-compacting concrete (SCC) in new construction. The current study revolves around SCC made of locally available materials and the harsh environmental conditions. This paper deals with the investigation into the effect of the water to powder ratio and...

ENVIRONMENTAL DEGRADATION OF DISSIMILAR AUSTENITIC 316L AND DUPLEX 2205 STAINLESS STEELS WELDED JOINTS
PublikacjaThe paper describes structure and properties of dissimilar stainless steels welded joints between duplex 2205 and austenitic 316L steels. Investigations were focused on environmentally assisted cracking of welded joints. The susceptibility to stress corrosion cracking (SCC) and hydrogen embrittlement was determined in slow strain rate tests (SSRT) with the strain rate of 2.2 × 10–6 s–1. Chloride-inducted SCC was determined in the...

Canonical switched capacitor converters. Comments, complements, and refinements
PublikacjaSwitched Capacitor Converters (SCC) form useful blocks in low/medium power applications as they are suitable for integration, both as off-chip and on-chip IC realizations. However, the problem with SCC is that their voltage conversion ratio is topology-dependent. By changing the SC circuit configuration, we can gain control over voltage conversion but the available ratio remains of a discrete nature, i.e. it maps into a countable...

Designing a High-sensitivity Microscale Triple-band Biosensor based on Terahertz MTMs to provide a perfect absorber for Non-Melanoma Skin Cancer diagnostic
PublikacjaNon-melanoma skin cancer (NMSC) is among the most prevalent forms of cancer originating in the top layer of the skin, with basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) being its primary categories. While both types are highly treatable, the success of treatment hinges on early diagnosis. Early-stage NMSC detection can be achieved through clinical examination, typically involving visual inspection. An alternative,...

Molecular identification and genotyping of Staphylococci: genus, species, strains, colnes, lineages, and interspecies exchanges
PublikacjaStaphylococci 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....

Advanced ultra super critical power plants: role of buttering layer
PublikacjaDissimilar metal welded (DMW) joint plays a crucial role in constructing and maintaining ultra-supercritical (USC) nuclear power plants while presenting noteworthy environmental implications. This research examines different welding techniques utilized in DMWJ, specifically emphasizing materials such as P91. The study investigates the mechanical properties of these materials, the impact of alloying elements, the notable difficulties...

Towards spectral sensitivity curve for two-photon vision mechanism
PublikacjaAbstract Purpose: The perceived brightness of different visible light sources can be compared with photometric units based on the standardized luminosity curves (300-780nm range). As reported previously (PNAS 111(50), pp. E5445-E5454 (2014)), near-infrared (NIR) radiation can cause isomerization of visual pigments by one- or two-photon absorption. The perceived color of the stimulus is red in the case of one-photon vision (1PV)...

Naprężeniowe pękanie korozyjne symulowanych stref wpływu ciepła złączy spawanych stali dulpeks
PublikacjaPrzedstawiono wyniki badań podatności do naprężeniowego pękania korozyjnego symulowanych stref wpływu ciepła złączy sapwanych stali austenityczno-ferrytycznych typu dupleks 2205. Strukltury SWC otrzymano na oprowym symluatorze cykli cieplnych. Testy korozyjne przeprowadzono metodą rozciągania przy niewielkiej szybkości odkształcenia w środowisku wrzącego roztworu MgCl2.

Eigenschaften der selbstverdichtenden Betone mit zerstreuter Bewehrung.
PublikacjaReferat dotyczy badania wpływu różnych domieszek upłynniających i dodatków(mikrowypełniaczy oraz włókna stalowego i polipropylenowego) na właściwości mieszanki betonowej samozagęszczalnej jaki na parametry betonu stwardniałego. Badania prowadzono w dwóch etapach. W etapie I opracowano receptury kilku mieszanek samozagęszczalnych bez dodatku włókien. W etapie II na mieszankach wytypowanych w etapie I po dodaniu różnych ilości...
