E. Olejnik, A. Janas, B. Grabowska, M. Kawalec, AGH University of Science and Technology, Faculty of Foundry Engineering, Krakow, Poland Casting technology was applied and research was carried out on two alloys based on the Ni3Al phase with variable carbon content of 0,2 and 1,25 wt. % C, respectively. Resistance to abrasive wear, friction coeffi cient and Vickers microhardness were determined....

A route to the top-down fabrication of highly ordered and aligned silicon nanowire (SiNW) arrays with degenerately doped source/drain regions from a bulk Si wafer is presented. In this approach, freestanding n- and p-SiNWs with an inverted triangular cross section are obtained using conventional photolithography, crystal orientation dependent wet etching, size reduction oxidation, and ion impla...

Patients with mitral stenosis are known to have a diminished ventilatory response to inhalation of carbon dioxide, as compared with normal subjects. Reduced responsiveness of the respiratory centre (Pauli, Noe, and Coates, 1960) and/or altered mechnical properties of the lungs are assumed to be responsible for this change (Bruderman, Braun, and Rogel, 1965). The ventilatory response to CO2 inha...

background: an epidemiological study was carried out on the vector(s) and reservoir(s) of cutaneous leishmaniasis in rural areas of kalaleh district, golestan province during 2006 - 2007. methods: totally 4900 sand flies were collected using sticky papers and were subjected to molecular methods for de­tection of leishmanial parasite. results: phlebotomus papatasi was the common species in outdo...

there is growing evidence that lectin-carbohydrate interactions can mediate the infection of parasites to their insect vector. many insect species are host or vectors of protozoan or metazoan parasites that cause socially and economically important disease such as malaria and leishmaniasis. however, relatively little work has been undertaken concerning the interaction of insect immunity against...

the notion of generalized locally bounded $i$-topological vectorspaces is introduced. some of their important properties arestudied. the relationship between this kind of spaces and thelocally bounded $i$-topological vector spaces introduced by wu andfang [boundedness and locally bounded fuzzy topological vectorspaces, fuzzy math. 5 (4) (1985) 87$-$94] is discussed. moreover, wealso use the fam...

In this paper, some properties of  pseudoinvex functions, defined by means of  limiting subdifferential, are discussed. Furthermore, the Minty vector variational-like inequality,  the Stampacchia vector variational-like inequality, and the  weak formulations of these two inequalities  defined by means of limiting subdifferential are studied. Moreover, some relationships  between the vector vari...

We call a local vector lattice any vector lattice with a distinguished positive strong unit and having exactly one maximal ideal (its radical). We provide a short study of local vector lattices. In this regards, some characterizations of local vector lattices are given. For instance, we prove that a vector lattice with a distinguished strong unit is local if and only if it is clean with non no-...
