We theoretically predict that the critical current ${I}_{c}$ and magnetization $M$ of a hybrid superconductor/normal-metal (SN) strip may have nonmonotonous dependence on perpendicular magnetic field---so-called peak effect. In contrast to familiar effect, which is connected either with vortex entry superconductor or peculiarities pinning, found phenomenon exists at low fields, in vortex-free (...

Understanding mechanisms that control plant root metal assimilation in soil is critical to the sustainable management of metal-contaminated land. With the assistance of the synchrotron X-ray fluorescence technique, this study investigated possible mechanisms that control the localization of Fe, Cu, Mn, Pb and Zn in the root tissues of Typha latifolia L. collected from a contaminated wetland. Me...

in order to study the effect of strip intercropping of maize (zea mays l.) and bean (phaseolus vulgaris l.) on the dry matter yield and land equivalent ratio (ler) in weedy and weed free treatments, an experiment was conducted at the agricultural station of college of agriculture, ferdowsi university of mashhad, iran. treatments were strip width of 2, 3, 4 and 5 rows and sole cropping of each c...

The paper investigates bronze rivets of a leather vessel from the burial ground Kichigino-I. These products small size are intensively corroded, which makes it impossible to strip them down metal. study patinated surface was carried out by X-ray fluorescence analysis (XRF) patina and relic metal scanning electron microscopy (SEM). results showed that were made arsenic-tin bronzes with an admixt...

The objective of this study was to assess the effects of heavy metals on microbial decomposition of cellulose in heavy metal-contaminated soils using a cotton strip assay. The assay is a measure of the potential of soil microorganisms to decompose the plant polymer, cellulose. Cellulolytic activity in soil was assessed by determining the reduction in tensile strength of the buried cotton strips...

This paper describes the results of work on the feasibility of using high frequency ultrasound to determine .the degree of bondedness of multilayer structures. A sandwich structure of two identical metal sheets of thickness on the order of 25 ~m, bonded together by a dissimilar third layer of thickness 10 ~m was examined. The primary disbond was expected to be in the region of the interface bet...

A novel compact, dual layer UWB monopole antenna is presented. This low profile ultrawideband antenna is fed by a 50 Ω shielded strip-line with an array of metal vias making the conducting walls. A printed disc monopole with a circular cut is the radiating element. The dual layer, shielded strip line feed allows for integration in multilayer technologies. The ultra-wideband, monopole characteri...
