Milking machine characteristics, as liner type, can influence milk flow trait and teat apex condition. The aim of the study was to investigate the effects of liner type on milk flow traits and teat apex condition. In addition, the age of the liner was taken into account. Four commercial farms were visited three times…
The paper reports the possibility of joint separation of 137 Cs and 85 Sr from neutral and alkaline aqueous solutions by their coprecipitation with the solid phase of complex compounds [M(18-crown-6)]BPh 4 (M=Na + , Cs + ), as well as to study the coprecipitation of 137 Cs and 85 Sr with the solid phase CsBPh 4 . It i…
Different from simple stimuli-sensitive microgels, herein, we report “self-oscillating” microgel. This microgel shows an autonomic and periodical swelling/deswelling oscillation that is synchronized with redox oscillation of the Belousov-Zhabotinsky (BZ) reaction. The cross-linked microgels were synthesized by the cop…
Multi quantum well structures in the deep blue emitted system 2-methyl-9,10-di(1-napthyl)anthracene (α, α-MADN) are fabricated. The device structures are optimized with respect to the layer thickness and number of pairs forming the quantum wells. The Electroluminescence spectra are de-convoluted into 3 peaks with peak…
To calculate the performance of energetic salts by applying thermo-chemical codes, new theoretical tools are required to predict their densities and formation enthalpies. The density of salts is evaluated using new models based on volume additivity. First, an existing group additivity method for neutral compounds has…
The current waste management strategy for spent nuclear fuel (SNF) mandated by the US Congress is the disposal of high‐level waste (HLW) in a geological repository at Yucca Mountain. Ongoing efforts on closed‐fuel cycle options and difficulties in opening and safeguarding such a repository have led to investigations o…
Based on the theory of pressure-shear gas gun, a new split Hopkinson pressure-shear bars (SHPSB) is developed in the paper through changing the shape of the incident bar's end. The end surface of incident bar is improved to in shape of cut-cone. By using the set, the constitutive beha- vior of specimens loaded by comb…
Approximately 20% of the processing steps in integrated circuit (IC) fabrication involve surface cleaning and removal of photoresist and plasma etch residues. Continuous device minimization requires the use of thin films (<20 nm), closely spaced features, and ultra shallow junctions (<50nm); as a result, the challenge…
The method of atomic-force microscopy is used to study the morphology of the surface of porous silicon layers formed on the p -Si substrate and obtained by anodic etching in an electrolyte with addition of free halogens (bromine, iodine) and potassium halogenides (KCl, KI). It is established that the presence of halog…
A multispectral sensor for in-situ cotton fiber quality measurement was developed. The sensor consists of a camera, four optical filters, a halogen light source, a fiber sampling device, and an image collection and processing system. The optical filters for the camera were selected based on the multiple linear regress…
The modulational instability of two incoherently coupled beams in azobenzene-containing polymer with photoisomerization nonlinearity is investigated analytically and numerically. Our results show that as a precursor to spatial optical soliton formation, modulational instability can be adjusted and controlled by the wa…
A new cluster time-of-flight secondary ion mass spectrometry (TOF-SIMS) was developed using a size-selected gas cluster ion as a projectile. Since a large gas cluster ion can generate many low-energy constituent atoms in a collision with the surface, it causes multiple and ultra low energy sputtering. The mean kinetic…
The shock to detonation transition was evaluated in the HMX based explosive PBXN‐9 by a series of light‐gas gun experiments. PBXN‐9 consists of 92 wt% HMX, 2wt% Hycar 4054 & 6 wt&percent; dioctyl adipate with a density of 1.75 g/cm3 and 0.8&% voids. The experiments were designed to understand the specifics of wave evo…
A formula for the dynamic spin susceptibility is derived in terms of the t-J-V model. This formula makes it possible to explain the main features of recent experiments on neutron scattering in the electron-doped superconductor Pr0.88LaCe0.12CuO4 − x . In particular, the proposed theory reproduces well a V-shaped relie…
Analytical model equations have been derived from the fundamental principles for effective relative permeability of circular multiple-inclusion magnetic structures like multiple split-ring resonators, spiral resonators and labyrinth resonators, useful for LHM applications. Tailoring of their resonant frequency, their…
We have investigated the effect of quantum dot (QD) concentrations, spin speed and temperature on the self assembly of CdSe/ZnS QDs on substrate for the optimisation of QDs used in organic light-emitting devices (OLEDs) applications. The atomic force microscopy (AFM) results showed that surface morphology and coverage…
This work is concerned with modeling the diffusion of atomic hydrogen on the surface of differently sized carbon nanotubes with different chiralities. The calculations were based on the estimation of activation energy by the density functional theory method and the use of transition state theory.
Abstract Interaction of metallic salts (M = Hg, Sb, and Te) with bis(triorganotin)oxide, (R3Sn)2O, where (R = C6H5, p‐CH3C6H4, and cyclo‐C6H11) at room temperature proceeded with the simultaneous cleavage of the SnC and SnO bonds, invariably yielding R2SnO along with other products. Thus the treatment of HgX2 (X = C…
We studied the significance of three processing parameters of supplied air pressure, yarn speed and overfeed ratio to the number and static strength of tangles of interlaced yarn and the correlation between the number of tangles and static strength of tangles by statistical method. Interlaced yarn was characterized by…
Highly oriented rutile and anatase TiO2:Co films have been grown on sapphire and SrTiO3 substrates by pulsed laser deposition with Co concentrations of 3% and 12%. All films are transparent with optical gaps >3 eV and show ferromagnetic behavior where the moment per Co ranges from 0.27 μB to 1.2 μB. The resistivity sh…
