Cable conductor temperature in operation is the key factor influencing insulation life,and cable operation state can be monitored through conductor temperature.Not only the value of temperature rise but also the change rate of conductor temperature is concerned.Generally the change rate of cable conductor temperature…
Combined the characteristics of cold extrusion with drawing process,a drawing-thickening technology with axial-force was prompted for double-cup-shaped workpieces.An axial thrust was exerted to the sidewall during backward drawing to achieve the purpose of drawing and thickening.The FEM software Dynaform was utilized…
As the energy debate enters a new chapter, the utility sector is revisiting an old favorite: nuclear power plants. In this article we will consider the pros and cons of nuclear power and the potential implications for utility bond holders. Coal is still the dominant fuel source in the U.S. producing almost half of all…
This paper surveys the present state of the art of diagnostics and removal techniques for particles suspended in plasma. Research on ldquodusty plasmasrdquo is necessary for ITER and fusion reactors of the future. The aim is to transfer the knowledge acquired in complex (dusty) plasma research and low temperature plas…
Th novel Quarc NoC architecture, inspired by the Spidergon scheme is introduced as a NoC architecture that is highly efficient in performing collective communication operations including broadcast and multicast. The efficiency of the Quarc architecture is achieved through balancing the traffic which is the result of t…
Active composite structures based on thermoplastic matrix systems exhibit a high application potential for lightweight structures ready for series production, due to the high specific mechanical properties as well as the high design freedom combined with economic and reproducible manufacture processes. Moreover, the i…
The presented studies have focused on a photocatalytic generation of useful hydrocarbons, mainly methane and ethane, from acetic acid under N2 atmosphere. CuO‐loaded rutile, as well as unmodified rutile and anatase‐phase TiO2 photocatalysts were applied in the experiments. The efficiency of the catalysts towards metha…
This paper discusses the chloride-induced corrosion of reinforcement in marine concrete structures focusing on the variability in the progress of deterioration. Through tests and analyses of reinforced concrete slabs taken out from existing open-type piers that have been in service for 30 to 40 years, the following ar…
Cu (copper) has been widely used for interconnection structure in integrated circuits because of its properties such as a low resistivity and high resistance to electromigration when compared with aluminum [1, 2]. Damascene process for the interconnection structure utilizes 2-steps CMP (chemical mechanical polishing).…
For the development of materials for contact lenses and intraocular lenses, the selection criteria is based on the (i) capacity to absorb and retain water, (ii) hydrophilicity and hydrophobicity, (iii) refractive index and (iv) hardness besides the other essential properties. Various monomers are being studied to deve…
The cuticle of spider's exoskeleton is a hydrophobic and non‐adhesive material, but the jumping spiders have the distinctive attachment apparatus for adhesion on smooth dry surface without sticky fluids. We have examined the whole tarsal appendages of the jumping spider, Plexippus setipes with using scanning electron…
A new rheocasting process was applied to develop a diesel engine block using ADC10 alloy. This type of diesel engine block requires much higher mechanical properties for a high engine power, and this is why heat treatment for improving mechanical properties should accompany processing. Therefore, the manufacturing pro…
A new negative tone imaging with application of new developer to conventional ArF immersion resist materials is proposed to form narrow trench and contact hole patterns, which is promising for double patterning process, since it is difficult to obtain sufficient optical image contrast to print narrow trench or contact…
The solubility of nitrogen in liquid silicon equilibrated with silicon nitride and its dependence on the composition of the atmosphere has been studied in the temperature region 1428–1542°C. High purity silicon was melted in silicon nitride crucibles under Ar and N2 atmospheres. The equilibrium was observed to be esta…
We propose a model to describe the formation of a spin-polarized half-metallic state in the proximity of a ferromagnetic metal monolayer embedded into a semiconducting host. The main physical ingredients of our model are the Coulomb interaction between two electrons at the same metallic site, the charge redistribution…
Magneto-thermo-gravimetric (MTG) technique is highly informative about the changes in the magnetic state, as well as structural changes in a system, which cannot be often noticed in calorimetric me ...
The behaviour of the 31 mer peptide (Ac-NSFVNDIFERIAG(13)EASRL(18)A(19)H(20)YNKRS(25)TITSRE-NH(2)), modelling the histone-fold domain (63 to 93 residues) of H2B, towards Ni(ii) was investigated by multidimensional NMR spectroscopy (1D, 2D TOCSY, NOESY and (13)C-HSQC). The coordination involved the imidazole of His20 a…
This paper is concerned with the study of metallorganic chemical vapor deposition (MOCVD) anatase film growth, with the aim of assessing the relationship between the surface morphology and the photocatalytic properties of the films, particularly their relation to the decomposition of ethylbenzene at in humidified air.…
The influence of N-substituents on the mode of reaction of ortho-quinones generated by oxidation of N-substituted dopamine derivatives has been studied. Ortho-quinones with amide, urea or guanidine side chains are relatively stable, with evidence of rearrangement to para-quinomethanes. The N-methylthiourea derivative…
Two arene-capped macrobicycles (1 and 2) incorporating the tris(pyrazolyl)methane (Tpm) chelate have been prepared from a benzylthiol-functionalized Tpm precursor (3). Reaction of either macrobicycle with Cu(CH3CN)4+ leads to tetrahedral or trigonal-planar, fluxional complexes incorporating the Cu(CH3CN)+ subunit ([Cu…
