A model filtration device with diatomaceous earth (DE) as a filter bed was used to investigate the effects of β-glucans, wort pH, maltose concentration, shearing, and shearing temperature on the efficiency of wort filtration at 76°C. A 0.45-μm membrane filtration of wort was performed at 20°C as an alternative test. H…
Ramie is a strong and lustrous bast fibre obtained from the inner bark of Boehmeria nivea (L) Gaud. The fibres are embedded in the cells of bast that lies between the outer bark and the woody core of the stem. The spinnable fibres are obtained by decOltication and degumming. It is not normally possible to spin the fib…
In this part of our study, we report the results of an experimental analysis of the structural and attributive blending modes discussed in Part I. This analysis results in a number of interesting findings relevant to the nature of multiple-component fiber blends. In the case of cotton/cotton blends, cotton fibers of s…
Abstract The Electrochemical Impedance Technique was used to evaluate the influence of a microbial consortium, isolated from a gas pipeline, upon API XL52 steel corrosion rate. The bacteria growth exhibited two different kinetics behavior, one for the plancktonic and the other for the sessile phase. The sessile bacter…
Reflective liquid crystal displays (LCDs) attract considerable interest for being light and having low power consumption. We proposed a new type of reflective LCD mainly comprising a hybrid-aligned nematic LC layer, biaxial retardation films, a light-diffusing film and a mirror electrode. This new type of reflective L…
The new compounds Rb 2 CuTaS 4 (1), Rb 2 CuTaSe 4 (2), RbCu 2 TaSe 4 (3), K 3 Ag 3 Ta 2 Se 8 (4), and Rb 3 AgTa 2 Se 12 (5) have been synthesized by the reactive flux method at 773 or 873 K. Their crystal structures were determined by single crystal X-ray diffraction. Crystal data for 1: space group Fddd, a = 5.598(1)…
Abstract An ethylene‐acrylic acid copolymer (EAA), either alone or combined with a low molar mass bis‐oxazoline compound (PBO), has been used as a compatibilization promoter for blends of polyamide‐6 (PA6) with low‐density polyethylene (LDPE). The effect of compatibilization on blend processability in injection moldin…
The contrast of antiferroelectric liquid crystal (AFLC) displays working on transmissive mode is degraded by the presence of pretransitional effect. Contrast is significantly enhanced by the use of orthoconic materials, i.e., AFLC mixtures with 45° smectic cone half angle. However, current orthoconic materials usually…
The atomic structure of dislocations in cubic boron nitride has been investigated by high resolution transmission electron microscopy. Most of the perfect dislocations, screw and 60° edge, are dissociated. A 60° dislocation which was undissociated has been analysed. Computer simulation is performed in an attempt to ch…
The principal aim of Professor John N. Sherwood in his research career has been the development of methods for the production of high quality crystals, principally organic crystals, the assessment of their perfection, and the role of lattice defects in solid-state processes. This perspective describes the background t…
The viscosities of maple syrup, 0.32 ± 0.03 Pa s, molasses, 0.87 ± 0.09 Pa s, ketchup, 9.8 ± 1.0 Pa s, and smooth peanut butter, 1.2 ± 0.9 × 105 Pa s, were measured at 25 °C and 1 bar pressure for comparison with the viscosities of natural silicate melts to aid in teaching the importance of viscosity in igneous proces…
Very first test results obtained from an intrinsic single crystal CVD diamond detector are described and compared to those measured with polycrystalline CVD-diamond and HPHT Ib diamond sensors. The data are discussed in the context of the requirements of intermediate and high energy heavy-ion physics experiments. It i…
The refractory metals are mostly suitable material for fabricating first mirrors for plasma diagnostics in a fusion reactor. Their low sputtering yields under the impact of charge exchange atoms can guarantee long-term mirror operation. An important factor influencing the rate of mirror degradation and reproducibility…
High-speed vehicle structures have been of interest since the earliest days of aviation. Every since that fateful day at Kittyhawk, North Carolina, the quest for speed has been inseparable from the world of aviation. Some of the advances in structures technology are explored specifically for hypersonic flight vehicle…
Ferroelectric Bi 3.6 La 0.4 Ti 3 O 12 (BLT) and Mn-doped (0.1 wt%, 0.2 wt%, and 0.3 wt%) BLT thin films were prepared by sol-gel processing. In the X-ray diffraction (XRD) results, all films exhibited a randomly oriented perovskite phase. Concerning surface morphology, the grain boundaries of the Mn-doped (0.2 wt%) BL…
Transformation of Escherichia coli plays an important role in recombinant DNA technology. Most current transformation protocols require that the cells be treated to attain a particular physiological state known as "competence," and this makes transformation procedures lengthy and arduous. Here we describe a protocol f…
Abstract The metastable nanocrystalline γ form of gallium oxide has been prepared and its microstructure and thermochemistry have been studied for the first time by employing X-ray and electron diffraction, high-resolution transmission electron microscopy, adiabatic and differential scanning calorimetry. The randomly…
Some technological parameters of ostrich skins and leathers, which are considered to be important in the leather industry, were analysed. It was observed that these parameters vary according to whether skin comes from the neck, leg and back sides. However, on the basis of area and strength values, leg and back sides a…
3-[ω-(p-methoxyphenoxy)alkyl] thiophenes were synthesized and electrochemically polymerized on ITO/glass electrodes by the potentiostatic method. Short alkyl chains substituted thiophene derivatives are generally difficult to polymerize by electrochemical methods, however, potentiostatic deposition provided h…
This paper presents partial-discharge (PD) analysis as a tool for predictive maintenance for medium-voltage switchgear systems. PD analysis is the newest technology being applied to MV electrical equipment and can detect corona or surface tracking behind metal barriers. This online PD monitoring proved that the equipm…
