Survival kinetics of lactic acid starter cultures were modeled considering the microorganism and external medium interfacial area as the critical factors determining the resistance of the microorganisms to freeze-drying. Surviving fraction of the microorganisms increased with the increasing biomass concentration during freeze-drying, and this is attributed to the mutual shielding effect of the microorganisms against the severe conditions of the external medium. Survival of the microorganisms over the storag...
Genetic control of rooting ability of lodgepole pine cuttings
Fries, A; Kaya, Zeki (1997-11-01)
This study evaluates the genetic control of rooting ability ex vitro for cuttings of lodgepole pine (Pinus contorta var. latifolia Engelm.). More than 200 clones from 21 full-sib families were studied during 4 yr in the greenhouse. Clonal averages in rooting frequency, root size score, shoot extension during rooting, and vitality score were calculated, together with variance components and phenotypic and genetic correlations among variables. Years, families within latitude of origin, clones within families ...
Growth factor loaded silk fibroin/PEGDMA hydrogels for articular cartilage tissue engineering
Fathi Achachelouei, Milad; Tezcaner, Ayşen; Engin Vrana, Nihal; Department of Biomedical Engineering (2018)
The aim of this study was to develop bFGF and TGF-β1 loaded polymeric nanoparticles (PNPs) and dental pulp stem cells (DPSCs) containing dimethacrylated poly(ethylene glycol) (PEGDMA)/silk fibroin hydrogels as scaffolds for regeneration of the cartilage tissue. Poly(lactic-co-glycolic) acid (PLGA) nanoparticles (NPs) were prepared with double emulsion-solvent evaporation technique. The effect of different excipients (poly(2-ethyl-2-oxazoline) (PetOx), heparin and Kolliphor P 188) on the entrapment efficienc...
Growth rate of switched homogeneous systems
Tuna, Sezai Emre (Elsevier BV, 2008-11-01)
We consider discrete-time homogeneous systems under arbitrary switching and study their growth rate, the analogue of joint spectral radius for switched linear systems. We show that a system is asymptotically stable if and only if its growth rate is less than unity. We also provide an approximation algorithm to compute growth rate with arbitrary accuracy.
