The uranium-gold diantimonide UAuSb2 belongs to a numerous family of ternary compounds crystallizing in a tetragonal structure of the HfCuSi2-type (space group P 4/nmm). In this paper the results of magnetization, electrical resistivity and thermopower measured along the main crystallographic directions are reported.…
The roll forming process is commonly used for the conventional 'Fe' metal products such as a furniture drawer guide or an up-down slide guide. Recently its applications are variously expanded to the sanitary facilities or electronic devices. It is essentially required the cleanness for the high technology application…
Purpose: The high-temperature plastic deformation is coupled with dynamic processes of recovery influencing the structure and properties of alloys. One of crucial issues is finding the interdependence between the hot plastic deformation process parameters, the structure and properties. Design/methodology/approach: Hot…
The article presents the results of investigations, which make a fragment of the broad-scale studies carried out as a part of the statutory activity on optimising the foundry sand technology using new, modified, inorganic binders.The results of investigations regarding the effect of lustrous carbon carriers on the tec…
Description Fourteen peer-reviewed papers present the latest advances in electrochemical techniques for corrosion monitoring, measurement, modeling, and life prediction in the laboratory and in the field. Five sections cover: Keynote papers—electrochemical techniques in corrosion and electrochemical standards for corr…
This chapter contains sections titled: Introduction Macronutrients and Phytoplankton Nutrient Supply Versus Demand the Modern Ocean The Biogeochemical Cycle of Nitrogen Flexing the Redfield Ratio: From Cultures to the Oligotrophic Ocean Silica: The bodybuilder Macronutrients in the Ocean: Future Trends
A new ternary compound, Ti 4.2-4.3 Dy 0.8-0.7 Sn 3 ( ), was found in the Ti-Dy-Sn system. It exists at an almost constant concentration of tin (~36.5 at.%), but has a certain homogeneity region (8.2 to 10.2 at.% Dy) due to mutual substitution of titanium and dysprosium. The crystal system was determined to be hexagona…
Buckybowls, bowl-shaped π-conjugated aromatic hydrocarbons corresponding to partial structures of fullerenes or cap structures of carbon nanotubes, possess the interesting chemical and physical properties due to the unique curved aromatic surfaces. Development of efficient methodology to construct the highly strained…
This work aimed to characterize and quantify the nanoscale particles emitted by a typical heavy duty industrial photocopier and printer to assess the long term effect of these particles on occupational health. The measured data showed that the nanoscale particle count in the room increased by about 5 times when the ph…
By using a twodimensional numerical simulation of the fully hydrodynamic equations, the dynamics of the traveling wave convection in binary fluid mixtures with defects was studied. For the separation ratio Ψ=-06, the system changes from localized traveling wave to traveling wave （TW） convection with the defects with…
The effects of specimen thickness on tensile properties of medium carbon steel welds prepared under longitudinal oscillation were investigated. Medium carbon steel workpieces were welded at different frequencies and amplitudes of longitudinal oscillation. Frequencies and amplitudes of oscillations were varied in the r…
ZA27 alloy was produced under super high pressure.The remarkable changes of crystal structure and microstructure were analyzed by XRD and metallography microscopy.The results show that the interplanar crystal spacing and lattice index of Al-rich α phase reduce gradually with increasing pressure.When the pressure reach…
A sustainable metals industry is essentially based on a closed loop of metals,which is as far as possible free of quantity and quality losses in the social economic system.Quantity losses of aluminium along its life cycle can further be classified into two main categories:1)the deposited loss which is either landfille…
Amylase is the enzyme which breaks down down starch into glucose molecules and commonly called as glycoside hydrolase enzymes.Variety of microorganisms such as bacteria, fungi, actinomycetes are known to produce amylases outside of their cells to carry out extra-cellular digestion of starch to break starch into the so…
The damping and basic dynamic properties of a novel type of multifunctional hybrid material known as Metal Foam-Polymer Composite are investigated. This material is obtained by injection molding a thermoplastic polymer through an open cell Aluminum Foam, in essence creating two contiguous morphologies; an Aluminum Foa…
A differentially operated, continuous stirred tank reactor (CSTR) was used to study the kinet- ics of oxygen delignification. The delignification kinetics and reaction rate were determined at different temperatures, oxygen pressures and caustic concentrations on softwood kraft pulps. The kinetics are first order in re…
Bremsstrahlung will be produced when the metal target is bombarded by high energy electrons. Bremsstrahlung characteristics is discussed under the condition of optimal bremsstrahlung efficiency for the purpose of improving its quality. This paper simulates the bremsstrahlung characteristics, combining theoretical anal…
The radial power profile in a fuel pin is an important piece of information for transient analysis. Based on single fuel region assumption in the U-238 resonance treatment, CASMO-5 relies on an empirical radial distribution function for the U-238 resonance integral. The burnup-dependent radial power profile in a typic…
Gating structure of one dimensional Cr layer is experimentally obtained through the technology of laser focused atomic deposition. The periodicity of grating is （212.8±0.2） nm measured by atomic force microscope, which is just equal to half of the wavelength of laser standing-wave field. Then, based on the semiclassic…
Recognition of the presence of any disturbance and classifying any existing disturbance into a particular type is the first step in combating the power quality problem. Support Vector Machines (SVMs) have gained wide acceptance because of the high generalization ability for a wide range of classification applications.…
