The pneumatic powder injection is well-known and widely used with injection lances submerged into metal bath. However, sometimes better is to not introduce the lance below the liquid metal surface because of the metal splashing and introducing of gases into metal volume. In such a case non-submerged lance is used but…
Chicken by-products are not often processed into high-value products. One important application is the productionof high quality chicken gelatin to meet the needs of markets that are not amenable to beef gelatin. So, thepresent study deals with the production of gelatin from chicken skin, feet and bone. The extraction…
Prediction of the possibility for the formation of new compounds is an important problem of materials science. In the present study, different computer training methods (support vector machine; algorithm for calculating estimates; voting algorithms based on deadlock tests, logical regularities, and statistically weigh…
The deformation-thermal stability of a clusterized amorphous-crystalline structure prepared from a Cu60Fe40 powder mixture at a logarithmic strain e = 4.6 and subjected to isochronous (40 min) annealings at T a = 200–800°C has been investigated. Periodic changes (ΔT = 300°C) in the order and disorder with a maximum or…
UNLABELLED: The stimuli-induced release systems are able to respond to an external stimulus resulting in drug release in a controlled pattern. The origin of the external stimuli may be of physical, chemical or biological nature. Thermo-responsive delivery systems respond to the change in temperature and they were main…
Deeper waters impose considerable challenges for eventual remote pipeline repair and remote hot-tapping. The purposes of this study were (1) to replicate the thermal history of a laboratory-produced part-size sleeve-on-pipe mock-up, which was designed to replicate the geometry and highest restraint levels of a remote…
OBJECTIVE: To investigate the effect of amphotericinB (AmB) on migration and invasion of esophageal carcinoma Eca109 cells exposed to hypoxia and explore the molecular mechanisms. METHODS: Routinely cultured esophageal carcinoma Eca109 cells were treated with 0, 1.25, 2.5, or 5 µg/ml AmB in hypoxic condition (3% O2, 5…
Welcome to the WIT Press eLibrary - the home of the Transactions of the Wessex Institute collection, providing on-line access to papers presented at the Institute's prestigious international conferences and from its State-of-the-Art in Science & Engineering publications.
Ag-loaded TiO2 nanotube covered by a pH-sensitive membrane were prepared by coating a silane coupling agent KH550 accompanied with a two-step photo-grafting and anodization, and its physiochemical properties were characterized by means of SEM, TEM, EDS and AES. Also, the antibacterial activities of these samples were…
With their unique physicochemical properties including excellent stability and biocompatibility, large specific surface area, and easy surface modification, gold nanoparticles (AuNPs) can be used as delivery vectors for drugs, genes, proteins, etc. In addition, AuNPs have excellent photothermal effects and radiosensit…
Poly(methyl methacrylate) (PMMA) intraocular len (IOL) surface was treated with ammonia plasma first, followed by coating an anticoagulant drug of r-hirudin. The physical and chemical properties of these surfaces were characterized by the static contact angle, X-ray photoelectron spectroscopy and quartz crystal microb…
Solvothermal reactions of benzyl alcohol with 4,4'-bipyridine, PbCl2, and I2 in water and acetonitrile afforded a unique benzyl viologen mixed-haloplumbate containing chloride and iodide [(BV)2(Pb5I8Cl6)]n (1) (BV2+ = benzyl viologen or N,N'-dibenzyl-4,4'-dipyridinium). The anionic part of 1 may be visualized as havin…
Unusual conductive contaminants at oil-paper interface [particles, copper sulfide deposits, debris from previous faults, etc.] of transformers can be diagnosed by on-site off-line time-domain, Polarization Depolarization Current (PDC) measurement. Some results are presented in the case studies of this document.
Characteristic of solder bumps is that during technology processing and usage their material composition changes. We present a model for describing a growth of intermetallic compound inside a solder bump under the influence of electro-migration. Simulation results based on our model are discussed in conjunction with c…
The device for texturing of magnetic materials was made. The samples with magnetic texture were obtained. The electromagnetic properties of Z-hexaferrities composites were measured on microwave. It was show, those imaginary permeability composites with texture 1.5 times more that of an isotropic samples.
Cathodoluminophors for efficient field emission light sources should meet the demands that differ from those for phosphors used in black-and-white television. The existing white phosphors and mixtures on the basis of color phosphors, which can ensure the maximal luminous efficiency when used in cathodoluminescence lam…
Surface roughness by peaks and depressions on the surface of titanium dioxide (TiO2) thin film, which was widely used for an antireflection coating of optical systems, caused the extinction coefficient increase and affected the properties of optical system. Chemical mechanical polishing (CMP) is a very important metho…
In oil-immersed transformers, static electrification phenomenon is caused by insulating oil flowing on solid insulator such as pressboard (PB). In Japan, as a countermeasure, 1, 2, 3-benzotriazol (BTA) is used to suppress static electrification. But, recent years, it has been reported that static electrification pheno…
The investigation of emissive ability, lifetime, structure and component surface composition of scandate cathodes with a matrix of tungsten and of tungsten-rhenium matrix impregnated with barium-calcium aluminate (4:1:1 or 6:1:2 moles) with 0.5–5 weight nonuniform emission can be explained by formation of crystals up…
Electroless Nickel deposition on Copper metallization required a thin Palladium layer (<; 5nm) as catalyst for Copper activation purpose. By using several physical failure analysis approaches, Palladium-Copper inter-diffusion behavior was proven affected by flow rate variation of chemical solution during Copper activa…
