QUASI m-CAYLEY STRONGLY REGULAR GRAPHS
Kutnar, Klavdija,Malnic, Aleksander,Martinez, Luis,Marusic, Dragan Korean Mathematical Society 2013 대한수학회지 Vol.50 No.6
We introduce a new class of graphs, called quasi $m$-Cayley graphs, having good symmetry properties, in the sense that they admit a group of automorphisms G that fixes a vertex of the graph and acts semiregularly on the other vertices. We determine when these graphs are strongly regular, and this leads us to define a new algebro-combinatorial structure, called quasi-partial difference family, or QPDF for short. We give several infinite families and sporadic examples of QPDFs. We also study several properties of QPDFs and determine, under several conditions, the form of the parameters of QPDFs when the group G is cyclic.

Strouhal number of bridge cables with ice accretion at low flow turbulence
Gorski, Piotr,Pospisil, Stanislav,Kuznetsov, Sergej,Tatara, Marcin,Marusic, Ante Techno-Press 2016 Wind and Structures, An International Journal (WAS Vol.22 No.2
The paper concerns with the method and results of wind tunnel investigations of the Strouhal number (St) of a stationary iced cable model of cable-supported bridges with respect to different angles of wind attack. The investigations were conducted in the Climatic Wind Tunnel Laboratory of the Czech Academy of Sciences in $Tel{\check{c}}$. The methodology leading to the experimental icing of the inclined cable model was prepared in a climatic section of the laboratory. The shape of the ice on the cable was registered by a photogrammetry method. A section of an iced cable model with a smaller scale was reproduced with a 3D printing procedure for subsequent aerodynamic investigations. The St values were determined within the range of the Reynolds number (Re) between $2.4{\cdot}10^4$ and $16.5{\cdot}10^4$, based on the dominant vortex shedding frequencies measured in the wake of the model. The model was oriented at three principal angles of wind attack for each of selected Re values. The flow regimes were distinguished for each model configuration. In order to recognize the tunnel blockage effect the St of a circular smooth cylinder was also tested. Good agreement with the reported values in the subcritical Re range of a circular cylinder was obtained. The knowledge of the flow regimes of the airflow around an iced cable and the associated St values could constitute a basis to formulate a mathematical description of the vortex-induced force acting on the iced cable of a cable-supported bridge and could allow predicting the cable response due to the vortex excitation phenomenon.

b-1,3-glucanase class III promotes spread of PVYNTN and improves in planta protein production
David Dobnik,Spela Baebler,Polona Kogovsˇek,Marusˇa Pompe-Novak,Dejan S ˇ tebih,Gabriela Panter,Nikolaja Janez,Dany Morisset,Jana Zˇ el,Kristina Gruden 한국식물생명공학회 2013 Plant biotechnology reports Vol.7 No.4
Glucanases are enzymes regulating the size exclusion limit and permeability of plasmodesmata and play a role in biotic stress. In plant genomes, they are encoded as relatively large gene families divided into four classes. Most studies of plant virus interactions have focused on glucanases from classes I and II. In our study, we have evaluated the role of the b-1,3-glucanase class III (Glu-III) gene in the potato–potato virus YNTN (PVYNTN) interaction and implemented the findings to plant biotechnology application. Potato cultivars De´sire´e and Sante´, which are tolerant and extremely resistant to PVYNTN, respectively, were stably transformed with Agrobacterium tumefaciens harbouring constructs for Glu-III overexpression. Localization of Glu-III protein in patches within the cell wall was determined by tagging the Glu-III protein with green fluorescent protein. Transgenic and nontransgenic plants were challenged with PVYNTN and its multiplication and spreading was followed. Differences in viral spread were observed between transgenic lines overexpressing Glu-III and non-transgenic lines, with stronger and faster viral spread in transgenic De´sire´e, and some multiplication in transgenic Sante´. In addition, the ability of Glu-III to improve in planta protein production after agroinfiltration was tested. The results have shown that Glu-III overexpression enables faster spreading of vectors between cells and better protein production, which could be beneficial in improving in planta protein production system using viral vectors.
