    Probes for 4th Generation Constituents of Dark Atoms in Higgs Boson Studies at the LHC by M. Yu. Khlopov, R. M. Shibaev

    Published 2014-01-01
    “…The nonbaryonic dark matter of the Universe can consist of new stable charged species, bound in heavy neutral “atoms” by ordinary Coulomb interaction. Stable U- (anti-U)quarks of 4th generation, bound in stable colorless (U- U- U-) clusters, are captured by the primordial helium, produced in Big Bang Nucleosynthesis, thus forming neutral “atoms” of O-helium (OHe), a specific nuclear interacting dark matter that can provide solution for the puzzles of direct dark matter searches. …”

    Pregled dimenzioniranja Peltonove turbine by Ivana Sušanj Čule, Doris Vračević, Nevenka Ožanić

    Published 2021-12-01
    “…Kako se pri radu turbine javljaju vrlo složeni uvjeti tečenja i fizikalni procesi, optimizacija i samo dimenzioniranje ovakvog sustava je izazov. Primjerice, u radu turbine javljaju se četiri režima tečenja: (i) stacionarno tečenje u uzvodnim i dovodnim cijevima, (ii) slobodni pad mlaza vode nakon izlaska s mlaznice, (iii) tečenje sa slobodnom vodnom površinom na lopaticama Peltonove turbine te (iv) raspršeno dvofazno tečenje na kućištu Peltonove turbine. …”

    Orthogonally Additive and Orthogonality Preserving Holomorphic Mappings between C*-Algebras by Jorge J. Garcés, Antonio M. Peralta, Daniele Puglisi, María Isabel Ramírez

    Published 2013-01-01
    “…We study holomorphic maps between C*-algebras A and B, when f:BA(0,ϱ)→B is a holomorphic mapping whose Taylor series at zero is uniformly converging in some open unit ball U=BA(0,δ). If we assume that f is orthogonality preserving and orthogonally additive on Asa∩U and f(U) contains an invertible element in B, then there exist a sequence (hn) in B** and Jordan *-homomorphisms Θ,Θ~:M(A)→B** such that f(x)=∑n=1∞hnΘ~(an)=∑n=1∞Θ(an)hn uniformly in a∈U. …”
