Catheter based ultrasound ablation devices have been suggested as the least minimally invasive procedure for thermal therapy. The success of such procedures depends on accurately delivering the thermal dose to the tissue. One of the main challenges of such therapy is to deliver thermal therapy at the target location w…
Protein X-ray structures with non-corrin cobalt(II)-containing sites, either natural or substituting another native ion, were downloaded from the Protein Data Bank and explored to (i) describe which amino acids are involved in their first ligand shells and (ii) analyze cobalt(II)-donor bond lengths in comparison with…
Samarium ion doped in rare earth crystals are spectroscopically interesting system since samarium has many atomic transitions in the visible range. Single crystals of samarium doped CdF2 has been studied for its non linear behavior using the home made z-scan set up. The Z-scan technique is a simple experimental set up…
Speckle pattern texture analysis method is applied to measure surface roughness of human skin. The method is based on analyzing of a gray level co-occurrence matrix occurred from a speckle image of a rough surface. Paper with different surface roughness is used as a skin phantom. The roughness is controlled by profilo…
Spin systems consisted of single electronic spin S=1 of the NV center and nearby nuclear spins I=1/2 of 13C atoms disposed in diamond lattice near the center can be used as a small register of a quantum computer or as a sensor of a magnetic field. At odd number of nuclear spins eigenvalues of the spin systems at zero…
This paper considers ionization equilibrium of thermal multicharged plasmas of simple gases and describes calculations of charges of the mean ion (MI) and the most represented ion (RI). A consideration is carried out by means of the Saha-Raizer method. The obtained results are compared with a solution of the Saha equa…
International martime organization (IMO) has approved< Performance standard for corrosion resistant steel for cargo oil tanks of oil tankers> and considered corrosion resistant steel as the only alternative for anti-corrosion coating since May 2010.The implementation of the standard will have a profound impact on ship…
Human leukocyte cell-derived chemotaxin 2 (LECT2) is a chemotactic factor for neutrophils that plays multifunctional roles in liver regeneration, regulation of neuritic development and proliferation of chondrocytes and osteoblasts. In addition, the C-terminal region of LECT2 belongs to the zinc metalloendopeptidase M2…
Abstract Of the differences between gas quenching and immersion quenching processes, the major difference is the presence of boiling during the early stages of quenching in oil or water. The formation of a vapor phase has a dramatic effect on both the overall and local rates of heat removal from the parts being quench…
The high demand of flexible electronics and the miniaturization of electronic components have been increasing very rapidly. Nanotechnology and in particular nanoparticles have become very important for the development of new technologies and applications which depend on the synthesis and characterization of nanopartic…
Abstract A novolac like phenolic resin was prepared by copolymerization with phenol and hydrolyzed starch as the substitute for formaldehyde under catalysis of sulfuric acid. Liquefied phenolated lignosulfonate was introduced to the phenol–starch resin in this study as a partial phenol substitute. The phenol–formaldeh…
ZSM-5 zeolites were hydrothermally synthesized in three different seeding pathways under the direction of tetrapropylammonium bromide (TPABr) template. In order to investigate the seeding effect in ZSM-5 crystallization process, ZSM-5 crystals and pre-fabricated MFI-type nanoseeds were added into the original self-ind…
Tellurite glasses following the molar concentration 71.5% TeO2, 22.5% WO3, 5% Na2O and 1.5% Nb2O5 have been investigated. Samples doped with Tm2O3, Pr2O3, Yb2O3 or Bi2O3 were fabricated by the conventional melt quenching process. Rare-earth (RE) 3+ ions have well defined emission bands. On the other hand, Bismuth emis…
Injury is an inevitable part of life, making wound healing essential for survival. In postembryonic skin, wound closure requires that epidermal cells recognize the presence of a gap and change their behavior to migrate across it. In Drosophila larvae, wound closure requires two signaling pathways [the Jun N-terminal k…
Abstract The compound (4‐H2pya)3[Al(OH)6Mo6O18]·5H2O (1) transforms into two 2D hybrid species (4‐Hpya)[(4‐Hpya)Ln(H2O)5]2[Al(OH)6Mo6O18]2·13H2O {Ln = Ce (2), La (3); 4‐Hpya = 3‐(4‐pyridyl)acrylic acid} in the mother liquor through crystal dissolution and recrystallization; this represents a rare example of in situ re…
The electrical performance of low-temperature polycrystalline silicon thin-film transistors (TFTs) is greatly affected by structures such as channel geometry, lightly doped drain, film thickness, etc. In this paper, the split channel polycrystalline silicon TFTs are fabricated through the silicide seed induced lateral…
Atomistic modelling techniques and Rietveld refinement of X-ray powder diffraction data are widely used but often result in crystal structures that are not realistic, presumably because the authors neglect to check the crystal-chemical plausibility of their structure. The purpose of this paper is to reinforce the impo…
Recoil effects in valence band X-ray photoelectron spectroscopy (XPS) are studied for both abb-trifluorostyrene and styrene molecular crystal systems. The gradual changes of XPS spectra excited by several photon energies are theoretically investigated within the tight-binding approximation and harmonic approximation o…

A facile approach to ultrafine hydrophilic polymeric nanoparticles within 10 nm is developed by anhydrous or aqueous inverse microemulsion polymerization of N,N-dimethylacrylamide. Since auto- precipitation of products occurs without any demulsifiers, the recycling of surfactants is feasible. The auto-precipitation me…
