An explosion and fire in a BOMARC-missile launching pad in June 1960 resulted in the direct release of weapons grade plutonium (WGP) within the confines of an Air Force site in central New Jersey. The site had undergone a large-scale remediation and final status survey (FSS) in 2002 to 2004 that resulted in over 20,00…
Ozet Doku muhendisligi, hem yumusak hem de sert doku onariminda ve yenilenmesinde kullanilan onemli yaklasim- lardan biridir. Bu yaklasimda, etkin vaskulerizasyona ve boylece 3 boyutlu hucre buyumesini saglayacak, yuksek ve acik gozenek yapisnda doku iskelerine gereksinim vardir. Bu iskeleler yumusak doku ve organlar…
Introduction Diseases of the musculoskeletal system are a main reason for early retirement and euthanasia of race, pleasure, and working horses. Mesenchymal stem cells (MSCs) have been recently investigated for their potential use in regenerative medicine. MSCs, in particular, have great potential, as in various repor…
This paper presents a hybrid high gain multi-resonance antenna. A rectangular split ring planar metamaterial antenna and rectangular slotted planar antenna are hybridized to achieve multi- resonance and high gain. This work is based on a rectangular slotted antenna of three iterations. The single structure provides bo…
One of perspective directions of a solid-state electronic engineering is producing new devices on the basis of ferrite-piezoelectric materials. Design and application of new microstrip microwave attenuator are considered.
1brick by reacting with the brick's SiO 2 glassy phase. This reaction is accompanied by a re duction in brick material which is shown by the greyish colour of used bricks. The trans formation leads to the formation of albite (Na 2O · Al 2O3 · 2 SiO 2) or nepheline (Na 2O · Al 2O3 · 6 SiO 2) in the contact area of liqu…
This paper describes the fluidity behaviour of continuously irradiated glasses using the Congruent Bond Lattice model in which broken bonds – configurons –facilitate the flow. Irradiation breaks the bonds creating configurons which at high concentrations provide the transition of material from the glassy to liquid sta…
Out-of-plane losses are the major issue in the integra- tion of two-dimensional photonic crystal devices in photonic inte- grated circuits. In this paper, we show that the out-of-plane losses of pillar-based photonic crystal waveguides can be vastly reduced, evenforpillarswithalowverticalindexcontrast,suchasinInP/In-…
By quite a lot of experimental observations, it is now generally accepted that the plasma transport in the scrape-off layer (SOL) is characterized by turbulent intermittency. This process, known as (higher density) blobs which are projected on the wall, increases the wall erosion and reduces the divertor efficiency. I…
Mechanical properties of cast hardened high-chromium steel are studied. Cast sections have lower properties as compared to forged blanks. Increase in cooling rate and isothermal annealing permit recommending the cast section instead of the forged blank.
This paper provides an outline of the issues and cha llenges in the successful d ecommissioning of a R&D tritium facility undertaken for the very first time at the Atomic Weapons Establishment (AWE) Aldermaston UK. It goes onto describe the Safety Management, technical and commercial arrangements for the detailed off…
In this paper a new generalized transformer model is developed.,based on the magnetic circuit. The model can be used in the general and special transformer’s simulation. The model is relative to the transformer structure and parameters of model can be gotten from the structure characteristic of transformer. The establ…
A major potential difference between polymer and small molecule organic light-emitting devices is the possibility of spin-dependent charge recombination in the latter. In this case, the singlet exciton formation yield, one of the key parameters that determines device efficiencies, deviates from the simple quantum mech…
We present the nature of bonding in chromium chalcogenides (CrX; X = S and Se) using equal-valence-electron-density (EVED) Compton profiles. For the Compton measurements, we have used 20 Ci 137Cs Compton spectrometer. We have also computed the Compton profiles using Hartree Fock (HF) and B3LYP schemes. The experimenta…
PROPOSED MODEL FOR GRAIN ALIGNMENT IN YBa 2 Cu 3 O 7-x (123) SUPERCONDUCTORS PREPARED BY MELT PROCESSING. A model for grain alignment in YBa 2 Cu 3 O 7-x is proposed. The proposed model is based on experimental results that the grain alignment in coarse samples with average grain diameter of 57 m is higher than that…
Wereview briefly the approach of Parisi and co-workers comprising replica Ornsein-Zernike integral equations with hypernetted chain closure to describe the glass transition for the model fluid of hard spheres . However , the original elements of the present communication are in the application of the expression for th…
The suspension polymerization of vinyl chloride is a complex process and requires elaborate formulations. These include suspending agents or protective colloids that play a key role in the particle formation process. In the suspension polymerisation of vinyl chloride the bulk monomer phase is dispersed in water by vig…
Nanocrystalline 12 2 19 BaFe Co Ti O xx x − with 01 x ≤ ≤ were prepared by a simple method of ball milling. Magnetic and SEM measurements show that the coercive field and average grain size is decreasing with the increase of Co-Ti substitution. IRM and DCD curves were measured in order to investigate the role of dopin…
Lead-free piezoelectric ceramics have attracted considerable attention as new piezoelectric materials for replacing Pb(Zr,Ti)O3 (PZT)-based ceramics because of environmental protection reasons. Among lead-free piezoelectric systems, the ternary system of Na0.5K0.5NbO3-LiTaO3-LiSbO3 has proven to be an outstanding lead…
Mg_<97>Zn_1Y_1RE_1 (RE=La, Ce, Nd and Sm, at. %) alloys were prepared by high-frequency induction melting in an Ar atmosphere. The rods were extruded with an extrusion ratio of 10 at 623K and a ram speed of 2.5mm s^<-1>. The microstructure and mechanical properties of the extruded alloys were investigated. Mg_<97>Zn_1…
