measurements of pb, cu, zn, as, ni, hg, and fe heavy metals and major elements and components such as ca, hco3, so4, na, k, mg and cl in soluble rain fractions were performed on rainwater collected at arak plain during the rainy seasons of 2012. concentrations of the heavy metals in the soluble fractions decreased for fe, pb, zn, ni, cu, as and hg, respectively and the major elements and compon...

Lymph node cells were obtained from an inbred strain of Lewis rats injected with guinea pig cord tissue in Freund's adjuvant. These cells, when added to tissue culture monolayers of puppy brain, aggregated on or around the glial elements. This reaction, called contactual agglutination, was followed by the specific destruction of glial cells, leaving cultures consisting only of fibroblasts. No s...

Elastomers and their composites are widely used in modern innovative technology: for the production of aviation automobile tires, anti-vibration elements (rubber, rubber-metal springs), dampers, elastomeric bearings. Also they shaft suspensions, as spacers between structural parts, supporting parts fasteners. Elastomeric structures have a high dynamic load, particular cyclic nature, which is ac...

In this paper we present new constructive methods, random and deterministic, for the efficient subsampling of finite frames in Cm. Based on a suitable strategy, are able to extract from any given frame with bounds 0<A≤B<∞ (and condition B/A) similarly conditioned reweighted subframe consisting merely O(mlog⁡m) elements. Further, utilizing deterministic method based principles developed by Batso...

Abstract We experimentally examine the thermo-resistive and thermo-piezoresistive sensitivity of multiwall carbon nanotube (MWCNT)/polypropylene random copolymer (PPR) nanocomposites processed via fused filament fabrication (FFF) process. The feedstocks were fabricated by melt blending neat PPR with a predetermined amount MWCNTs (either 4, 6 or 8 wt%) using twin-screw extruder. Thermo-resistive...

Visual representations of node-link diagrams are very important for the software development process. In many situations large diagrams have to be explored, whereby diagram elements of interest are often clipped from the viewport and are therefore not visible. Thus, in state-of-the-art modeling tools navigation is accompanied by time consuming panning and zooming. One solution to this problem a...

TOSCA is an upcoming standard to capture cloud application topologies and their management in a portable way. Management aspects include provisioning, operation and deprovisioning of an application. Management plans capture these aspects in workflows. BPMN 2.0 as general-purpose language can be used to model these workflows. There is, however, no tailored support for management plans in BPMN. T...
