It has been proposed that the outer cylinder of the drift chamber be changed from 1.6 mm carbon fiber (0.6% X0) to 2.5 mm aluminum (2.5% X0). While such a change would have only a slight effect on the barrel CsI calorimeter performance, the question has been raised as to how it might affect the DIRC. Multiple scattering in the outer cylinder would cause as uncertainty in the entrance angle and ...

  Three different materials (aluminum, ferro -silicon and silicon) were used as antioxidants in order to prevent the decarburization process and to keep and/or increase the final properties in MgO-C refractories. Their effects were compared by measuring the physical and mechanical properties as well as oxidation and the resultant phases and microstructures, in the temperature range of 200-1600 ...

5083 aluminum alloy is a light-weight and strain-hardened material used in high strain-rate applications such as those experienced under shock loading. Symmetric real-time (in situ) and end-state (ex situ recovery) plate impact shock experiments were conducted to study the spall response and the effects of microstructure on the spall properties of both 5083-H321 and 5083-ECAE ? 30 % cold-rolled...

background: entry of untreated wastewater of wool scouring factories has been associated with many environmental hazards because of high rate of pollution. presently effective treatment methods and reducing the costs of operation and maintenance from treatment units have always been under the attention of this industry owners. the aim of this survey is to present a suitable method for the treat...

The research presents the first results of aluminium speciation analysis in aqueous extracts of individual plant parts of Betula pendula and soil samples, using High Performance Ion Chromatography with Diode Array Detection (HPIC-DAD). The applied method allowed us to carry out a full speciation analysis of aluminium in the form of predominant aluminium-fluoride complexes: AlF(x=2,3,4)(3-x) (fi...

Fiber-metal laminates (FMLs) such as Kevlar reinforced aluminum laminate (ARALL), 18 Carbon reinforced aluminum laminate (CARALL), and Glass reinforced aluminum laminate 19 (GLARE) offer great potential for weight reduction applications in automobile and aerospace 20 construction. In order to investigate the feasibility for utilizing such materials in the form of 21 laminates, sheet hydro-bulgi...

Disturbance in water relations is the major causes of vase life reduction and senescence in cut flowers This problem is mainly due to microorganism proliferation in the vase solution which leads to vascular occlusion and reduction in solution uptake by cut flowers. Therefore a comprehensive study was conducted to evaluate the biocidal effect of nano silver particles (NSP) and compare it with so...

The ability of aluminum to inhibit the (Na(+)/K(+))ATPase activity has been observed by several investigators. The (Na(+)/K(+))ATPase is characterized by a complex molecular heterogeneity that results from the expression and differential association of multiple isoforms of both catalytic (alpha) and regulatory (beta) subunits. For instance, three main alpha (alpha(1), alpha(2) and alpha(3)) and...

in hot dip galvanizing, several parameters such as chemical composition of coating bath, immersion time and surface roughness of specimens could affect microstructure and properties of coating. in this article, the effect of aluminum content, immersion time and surface roughness on structure and properties of alloy layers have been investigated. specimens of low carbon silicon-free steel with d...
