Gross alpha and beta activities of airborne particulate samples from Wawel Royal Castle Museum in Cracow, Poland
(Springer, 2013)PM-10, PM-2.5 and PM-1.0 concentrations were measured over an 8 h period at sites both inside and outside the museum of Wawel Royal Castle in Cracow, Poland. Gross alpha (alpha) and beta (beta) activities seemed to vary ... -
Group-2-groupoids and 2G-crossed modules
(2019)In this paper, we introduce the notion of a group-2-groupoid as a group object in the category of 2-groupoids. We also obtain a 2G-crossed module by using the structure of a group-2-groupoid. Then we prove that the category ... -
Growth and characterization of CT(S,Se) thin films and Al/n-Si/p-CT(S,Se)/Mo heterojunction diode application employing a two-stage process
(Elsevier, 2023)Cu2SnS3 (CTS), Cu2Sn(S,Se)3 (CTSSe), and Cu2SnSe3 (CTSe) thin films were deposited on n-type silicon wafer substrates using a two-stage process. This process involved drop-coating Cu-Sn precursors, which is different from ... -
Growth and characterization of Cu2SnS3 (CTS), Cu2SnSe3 (CTSe), and Cu2Sn(S,Se)(3) (CTSSe) thin films using dip-coated Cu-Sn precursor
(Springer, 2019)Ternary compounds Cu2SnS3, Cu2SnSe3 and Cu2Sn(S,Se)(3) thin films used in thin film solar cell applications were prepared at the first time by such a two-stage process that includes dip-coating of Cu-Sn precursors as ... -
Growth modelling based on different feeding protocols of turbot (Psetta maxima)
(Wiley, 2022)Turbot (Psetta maxima) is a commercially valuable species in aquaculture, and the new strategies and models for growth are essential for rapid growth in aquaculture operations. Hence, the objectives of this study were to ... -
Growth of Cu2ZnSnS4 (CZTS) thin films using short sulfurization periods
(Iop Publishing Ltd, 2019)In this study CZTS thin films were grown by a two-stage process that involved sequential sputter deposition of metallic Cu, Zn, and Sn layers on Mo coated glass substrates followed by RTP annealing at 530 and 560 degrees ... -
