For the stabilization of insulation performance in resin-molded insulators, strong adhesion between the resin and ceramic is required. In this paper, a new technique for the control of the interfacial strength in resin-molded structures has been proposed. The adhesive strength of the internal interface in a resin-mold…
To determine the required thickness of a pavement is impossible without knowing the patterns of modes of deformation for continuous, stratified and grainy media under the effect of the recurrent traffic vertical and horizontal loadings. When exposed to variable temperatures, the deflected mode of the stratified paveme…
In this work we report a low cost technique, via simple rapid-mixture polymerization of aniline using an electrospun carbon nanofiber (CNF) paper as substrate, to fabricate free-standing, flexible CNF–PANI (PANI ¼ polyaniline) composite paper. The morphology and microstructure of the obtained products are characterized…
This paper presents the first data for bremsstrahlung buildup factor (BBUF) produced by the complete absorption of Y-91 beta particles in different materials via the Monte Carlo simulation method. The bremsstrahlung buildup factors were computed for different thicknesses of water, concrete, aluminum, tin and lead. A s…

The theory of nonlinear phenomena taking place under conditions of the anomalous skin – effect is presented. The nonlinearity is caused by the influence of the wave magnetic field on the dynamics of effective electrons. In the case of small wave amplitude A the imaginary part of the surface Z is proportional to A 2 ,…
We have developed a well-ordered metallic array of nanopillars in nanoholes fabricated simply by magnetron sputtering into a plastic nanohole array over a large area. The pillar height and pillar-hole gap were controllable to nanometer scales through the sputtering time and initial nanohole design, constructed by a na…
Solid state mechanochemical reactions between clay minerals and CsCl during grinding in non-destructive techniques, investigated in our laboratory, are reviewed. Clays were talc, pyrophyllite, sepiolite, palygorskite and minerals from the serpentine-kaolin and smectite groups. No reaction occurred with serpentines, ta…
The paper is devoted to a study of coupled harmonic thermoelastic impulse guided propagation through an infinite circular cylinder. Heat interchanging is supposed to take place between sidewall of the waveguide and environment. The analysis is carried out according to the principles of coupled generalized thermoelasti…

Nanocrystalline pure and CuO doped ZnO thin films were prepared using spray pyrolysis technique. The zinc nitrate (0.1 M) and copper chloride (0.1 M) were used as starting precursor. These films were characterized by XRD, SEM and EDAX to observe structural, microstructural properties and elemental analysis respectivel…
The Brazilian Multipurpose Reactor (RMB), now in the conception design phase, is being designed in Brazil to attend the demand of radiopharmaceuticals in the country and conduct researches in various areas. The new reactor, planned for 30 MW, will replace the IEA-R1 reactor of IPEN-CNEN/SP. Low enriched uranium (<20%…

was mathematically modeled using Monte-Carlo, single collision and pacing methods on the base of Mathcad program. The radiation-chemical yields of the physical (single ionized molecular orbitalsH2O + j (1a1, 2a1, 1b2, 3a1, 1b1), esub electron lost its energy up to a primary electron excited energy and electron-excited…
The study evaluates the influence of the interaction of oxidized, cationized and untreated fiber components upon paper properties. The oxidative treatment has been noted to improve fiber bonding, while degrading fiber strength. Comparatively, cationization has relatively reduced undesirable effects on the physical pro…
Chara drouetii R.D. Wood, 1965 was recently collected during floristic surveys of aquatic macrophytes in the Yucatán Peninsula, Mexico. This discovery represents the first documented record for this species from the state of Quintana Roo, Mexico. This report extends the range of Chara drouetii by approximately 300 km…
Die funkenerzeugenden Prozesse der Reib- und Schlagfunken konnten uber gezielte Betrachtungen und einen schmalen Bereich der Parameterbreite der jeweiligen Zundquelle verglichen werden. So zeigten Versuche bei einem Volumenanteil von c ≤ 10 % H2 und somit sehr kurzen Reibzeiten (t < 1,0 s) ahnliche Ergebnisse bezuglic…
The thin films of Cd1-xPbxS (0 ≤ x ≤ 1) have been deposited onto clean glass substrates by economical bath deposition technique. The deposition parameters were optimized to obtain good quality thin films. The absorption spectra of these films have been recorded using spectrophotometer. The energy band gap (Eg) and abs…
The work presents the research results of the influence of the selected technological factors on the improvement of bimetallic castings alloy steel-silumin. The following alloy steel grades were used for the research: X6CrNiTi18-10, X39Cr13 and HS6-5-2. The sets of the mentioned steel grades were alphinated in silumin…
The study was aimed to combine chicken legs skin gelatin and soy protein isolate as a raw material for edible films. The research materials used were chicken leg skin and soy protein isolate. There were two stages in the experimental. The first stage was processing of gelatin from chicken leg skin which soaked in 0.1%…
