The objective of this study was to develop empirical functions in order to predict vacuum drops in b and d-phase and in claw (or junction point) using response surface methodology (RSM) for both, conventional and quarter individual milking system. The independent variables considered in the study consisted of the syst…
The need to produce fuel efficient vehicles and reduced emissions has led the automotive industries to the use of the lightweight materials. The use of magnesium alloys through superplastic forming is very promising for this goal while it makes the manufacturing part less complex and reduces the weight of the parts ex…

We investigated the photonic band structure of a two dimensional (2D) circular photonic crystal (CPC) silicon membrane slab waveguide with surface coupling reflectivity (SCR) technique. Fano-like sharp resonance modes were found in the angle-resolved SCR spectra for both P- and S-polarized light. By extracting energie…
We design and analyze a novel multiband left-handed metamaterial based on a fishnet-like structure at terahertz (THz) frequencies. The metamaterial exhibits simultaneous negative refractions around the frequencies of 0.48, 1.05, and 1.19 THz for the electromagnetic (EM) wave normal incidence, and around the frequencie…
We have experimentally investigated the driving performance of liquid crystalline actuators, which are recently proposed for micro-actuators. In our experiment, the liquid crystalline material (5CB) is placed between two glass plates with surface orientation treatment. When a pulsed electric field is applied between t…
During the past 15 years many works have been done on Ageing Management Program (AMP) of Safety classed components in EDF. The paper will describe all the different aspects concerning these programs, and in particular the EDF step by step procedure and the major results. To-day, EDF is starting the 3rd ten-year shutdo…
Abstract
Organic light-emitting diodes (OLEDs) were fabricated with a structure of indium-tin-oxide (ITO)/polystyrene (PS): N,N’-bis-(3-naphthyl)-N,N’-biphenyl-(1,1’-biphenyl)-4,4’-diamine(NPB)/tris-(8-hydro-xyquinoline)-aluminum(Alq3)/Magnesium(Mg)/tris-(8-hydroxyquinoline)-aluminum(Alq3)/Mg:Ag.By insert- ing an ultrathin Mg…
Metamaterials have attracted a lot of attention over the last decade 1 and are destined to be the generic basis of applications in many areas of life. They are artificial composites and can be constructed in a variety of ways using some forms of artificial atoms and molecules, which can be termed metaparticles. In the…
By comparing ethanedithiol and benzenedithiol treatments, we demonstrate that the optical and electronic properties of self-assembled PbS nanocrystalline films heavily depend on the dithiol molecule used for the ligand-exchange process.
Nickel base alloys are commonly used in light water reactors because their properties for thermal exchange and also differential thermal expansion with carbon steels are good to very good. Unfortunately, the alloys 600 and 182 / 82 are sensitive to primary water stress corrosion cracking (PWSCC). The effect of the tem…
以Eu3＋为中心离子,4-（4-吡啶甲酰基）苯甲酸（HPFBA）、1,10-菲罗啉（Phen）和三苯基氧膦（TP-PO）为配体,合成了新型配合物Eu（PFBA）3（H2O）4,Eu（PFBA）3Phen（H2O）3和Eu（PFBA）3TPPO（H2O）3（PFBA=4-（4-吡啶甲酰基）苯甲酸根）。红外光谱表明,形成配合物后,HPFBA中羧基位于3000～2200cm-1处的羟基伸缩振动峰νO—H和1697cm-1处的羰基伸缩振动峰νCO消失,同时,在约1545cm-1处出现了羧基反对称伸缩振动吸收峰νas（—COO-）,约1415cm-1处出现了羧基对称伸缩振动吸收峰νs（—COO-）,且Δν（νas（—COO-）-νs（—C…
Luminescent nanodiamond is attractive for targeted drug delivery and biolabelling due to its unique optical properties, low cytotoxicity, and biocompatible surface moieties. Advances in production of single-digit luminescent nanodiamonds will be reported. We will present a versatile bioconjugation protocol to dock bio…
In this paper, two new combined cycle systems with/without CO2 capture based on methanol indirect combustion are developed, which have significantly higher efficiency than methanol fueled conventional combined cycle. The performance of the new systems is compared with conventional combined cycle to identify the potent…
We discuss the basic definitions and existing conclusion about periodicity of the twin Fibonacci sequence in this paper. The upper bound of the twin Fibonacci sequence and the least period of 3-dimensional Arnold transformation mod N are respectively 6.269N2 and 3.134N2, which is similar to two existing references. Mo…
It is suggested that quantum chemical calculations can he effective for discovery of new energetic materials (DEMTM). The key quantity for such discovery, which is unknown hut can he calculated, is the heat of formation for a tentative explosive material under investigation. There are two components to the heat of for…
Overall transmittance of porous cerium dioxide is measured in the spectral range of 900–1700 nm using dispersive spectroscopy. Dense and porous samples of cerium dioxide with average porosities of 0.08 and 0.72, respectively, are investigated. The transmittance of both sample types increases with decreasing thickness,…
Aqueous solutions were studied using photoelectron and Auger spectroscopy, based on synchrotron radiation and a liquid micro-jet setup.
