This introductory textbook emphasizes the fundamental principles of textile science and describes the basic processes of fabric manufacturing. The presentation comprises five parts: fibers, yarns, fabrics, colors and finishes, and fabric end uses. The fibers section contains chapters on fiber classification, theory, a…
Measurements of the frequency dependence of the room-temperature ferromagnetic resonance (FMR) linewidth have been performed in well-characterized barium hexaferrite single crystals at millimeter-wave frequencies. A shorted waveguide measurement technique was used to obtain very clean FMR profiles in the frequency ran…
Abstract In conventional multiphase Rietveld refinement, now being used for quantitative phase determination, the crystal structure of each phase needs to be known in order to generate a calculated standard pattern of the phase to be refined against the measured XRD pattern. This is a disadvantage when the structural…
Abstract Diagenetic K-feldspar overgrowths from the Permo-Triassic continental clastic sediments of the Elgin area in Scotland were examined using conventional petrographic techniques and transmission electron microscopy to investigate the mechanisms of feldspar authigenesis. The detrital K-feldspar in these rocks is…
An experiment was conducted to determine whether controlled internal drug release devices-type G (CIDR-G) could be used in conjunction with the ram effect to advance the breeding season and lambing and thereafter could be reapplied to stimulate breeding of ewes to produce a second lambing in late summer. Finn crossbre…
By means of Monte Carlo simulations, we examine the behavior of random packings of hard ellipses formed by pouring into a two-dimensional container. The particles pack so that their semimajor axes are preferentially aligned with the horizontal, and their orientational alignment increases with increasing aspect ratio.…

Three {V3O13} units linked to form a ring that encloses the central V atom are found in the VV title compound. The VIV/VV cluster consists of a layered structure composed of three {V2As2O4} rings. These are further examples of the exotic structures which are par for polyoxometalates. They show the profound influence t…
Abstract Oligomers of α‐pinene ( 1 ) with relatively high molecular weight (number‐average molecular weight M n = 1140, weight‐average molecular weight M w = 2590) were obtained with the binary catalyst AlCl 3 /SbCl 3 in toluene at − 15°C ([AlCl 3 ] 0 = 42,5 mmol · L −1 , mole ratio SbCl 3 /AlCl 3 = 0,50). The yield w…
The anomalous dielectric absorption current of BaTiO 3 ceramics when an electric field is applied at above the Curie point was measured. The results cannot be explained by the famous Maxwell-Wagner double layer theory. The total charge of the charging and discharging absorption current was more than 1000 µC/cm 2 . The…
Abstract An improved procedure for the anionic polymerization of hexamethylcyclotrisiloxane (D 3 ) initiated by a monofunctional lithium derivative is reported. The initiator seeding solution is preferably prepared in benzene, and tetrahydrofuran is used as a cosolvent which makes the presence of additional promoters…

Raman spectra are reported for fresnoite (Ba 2 Ti(Si,Ge) 2 O 8 glasses, and comparison is made between the Raman spectra of the corresponding crystalline powders and glasses of Ba 2 TiSi 2 O 8 and Ba 2 TiGe 2 O 8 . The Ba 2 TiGe 2 O 8 glass spectra show correspondence with the Ba 2 TiGe 2 O 8 crystalline Raman spectra…
Introduction of silver into a silicate glass often leads to reduction and coloration. The electron required for silver reduction is extracted from a nonbridging oxygen atom. The use of high-field-strength ions limits the number of nonbridging oxygens and silver reduction.
We present a phenomenological Landau–de Gennes-type theory of strain effects on concentration fluctuations in "soft" elastic two-component solids. Introducing concentration-dependent elastic moduli and a coupling between the strain and concentration fields we find that, for systems which exhibit nearly linear elastic…
Small droplets in size of 20--1000 \ensuremath{\mu}m of Al-Mn alloys have been undercooled by containerless solidification during free fall in a drop tube or by melt atomization. The as-solidified droplets were analyzed with respect to the phases formed from the undercooled melt by electron microscopy, x-ray diffracti…

The cubic magnetic anisotropy constants of ${\mathrm{Fe}}_{3(1\mathrm{\ensuremath{-}}\mathrm{\ensuremath{\delta}})}$${\mathrm{O}}_{4}$ single crystals (with 0.0000.006), obtained by curve fitting of the respective magnetization curves, are reported between room temperature and the isotropic point (\ensuremath{\sim}130…
The mixed chain triacylglycerol 1,2-dipalmitoyl-3-acetyl-sn-glycerol was synthesized and its crystal structure was determined to a final reliability factor (R) of 0.11. Two molecules are present in the monoclinic unit cell: space group P2(1); a = 5.375(1), b = 8.286(2), c = 42.96(1) A; beta = 93.30(2) degrees, V = 191…
