conclusion our preliminary results have shown that although there is some overlap between benign and malignant tumors, adding dwi, mr imaging to routine soft tissue tumor protocols may improve diagnostic accuracy. results there was only one patient with a malignant cystic tumor and was not included in the statistical analysis. the median adc values of benign and malignant tumors were 2.31 ± 1.2...

analytical chemistry has experienced, as well as other areas of science, a big change due to the needs and opportunities provided by analytical nanoscience and nanotechnology. now, nanotechnology is increasingly proving to be a powerful ally of analytical chemistry to achieve its objectives, and to simplify analytical processes. moreover, the information needs arising from the growing nanotechn...

In this research, M-type Mn-Zr doped Ba-ferrites powders with a general chemical composition of BaFe10.6(ZrxMn1-x)O19 ( x= 0, 0.2, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1) were synthesized and prepared by a solid state method, and were then mixed with anAraldite + hardner and processed into polymer matrix composite specimens. Phase analyses of synthesized samples wereperformed by an XRD technique and ...

In this paper, conjugate heat transfer of magneto hydrodynamic mixed convection of nanofluid about a vertical slender hollow cylinder embedded in a porous medium with high porosity have been numerically studied. The Forchheimer’s modification of Darcy’s law was used in representing the nanofluid motion inside the porous media. The governing boundary layer equations were transformed to non-dimen...

BACKGROUND Diffusion-weighted imaging (DWI) is a noninvasive method for investigation of tumor histological content. It has been applied for some musculoskeletal tumors and reported to be useful. OBJECTIVES The aim of the present study was to prospectively evaluate the apparent diffusion coefficient (ADC) values of benign and malignant soft tissue tumors and to determine if ADC can help diffe...

Background and purpose: In spite of many studies on composting from municipal solid wastes, rural solid wastes have not been studied. A high percentages of rural solid wastes containing domestic, animal and agricultural solid waste is biodegradable. The objective of this research was to study the chemical and microbial quality of compost produced by mixed rural solid wastes and other composts...

Spin chains have been proposed as quantum wires in many quantum-information processing architectures. Coherent transmission of quantum information in spin chains over short distances is enabled by their internal dynamics, which drives the transport of single-spin excitations in perfectly polarized chains. Given the practical challenge of preparing the chain in a pure state, we propose to use a ...

Mixed-order phase transitions display a discontinuity in the order parameter like first-order transitions yet feature critical behavior like second-order transitions. Such transitions have been predicted for a broad range of equilibrium and nonequilibrium systems, but their experimental observation has remained elusive. Here, we analytically predict and experimentally realize a mixed-order equi...
