The results of measurements third-sound velocity in adsorbed superfluid helium films (1.12-1.85\ifmmode^\circ\else\textdegree\fi{}K) are presented. It is found that the average fraction nonvanishing at superflow onset thickness and has a value about $\frac{3}{8}$ its bulk value. Possible reasons for discussed. Healing lengths based on best fitting Ginzburg-Pitaevskii calculations determined.
The control of magnetization using electric fields has been extensively studied in magnetoelectric multiferroic insulating materials while changes bulk metals caused by currents have attracted less attention. recently discovered metallic magnet ${\mathrm{Ce}}_{3}{\mathrm{TiBi}}_{5}$ reported to exhibit current-induced magnetization. Here we determined the magnetic structure neutron diffraction, aiming understand microscopic origin this phenomenon a metal. We established that...
The dimerization of anti-apoptotic BCL-xL by three-dimensional domain swapping has recently been discovered at alkaline pH; however, the high energetic barrier between dimer and monomer forms prevents them from interconverting room temperature neutral pH. Here, we demonstrate that dimers can be easily prepared heating concentrated protein above 50 °C. 38 kDa was fully characterized multi-resonance nuclear magnetic resonance (NMR) spectroscopy, mechanism α-helix confirmed. Dimerization...
SUMMARY Two groups of nine in-calf beef cows were given daily for the last 16 weeks pregnancy and first 6 lactation 1·35 increasing to 3·15 kg molassed sugarbeet pulp dry matter containing added urea together with oat straw ad libitum . Additionally, one group received supplementary dicalcium phosphate which increased their total phosphorus intake from about 12 28 g P/day. In absence supplementation, there was a marked significant reduction in concentration blood, by 4th week this reflected...
The angle-insensitive and tunable nature of metal–insulator–metal slits makes them an interesting candidate for plasmonic displays colorant applications. realization these structures in the visible regime over reasonably large areas has only been recently possible due to advances nanofabrication. However, previous demonstrations are inverted grooves etched into a dielectric, coated with metal then probed from substrate—leaving unable be tuned postfabrication, as regions confined fields...
SUMMARY Pregnant beef heifers allowed ad libitum access to oat straw were given 2·7 kg molassed sugar-beet pulp alone or with additional dicalcium phosphate urea a combination of both materials in Latin square design involving four feeding periods each 21 days. Supplementation increase the total daily intake digestible crude protein from about 130 290 g/day increased consumption by 20%. This metabolizable energy 13 15 Meal/day. Increasing phosphorus 6 17 g P/day did not digestibility either...
An acoustic device is described which measures the 3He concentration of a 3He–4He gas mixture. The was designed to provide an inexpensive system continuously monitor operation dilution refrigerator. isotopic fraction may be easily measured precision 1%.
SUMMARY In three experiments housed Greyface (Border Leicester × Scottish Blackface) ewes of mean live weight 68 kg received 0·91 hay plus molassed sugar beet pulp daily during the second half pregnancy and in first 3 weeks lactation. Comparisons were made with additions crude protein given as urea or groundnut cake either whole period only early one experiment, increasing intake digestible from 88 to about 140 g had no effect on lamb at birth weeks. other two experiments, which increases...
ABSTRACT Sugar-beet pulp as normally produced in Great Britain contains about 400 g molasses per kg dry matter (DM). It has been demonstrated that either a reduction the amount or even full removal of did not affect yield composition milk cows (e.g. Ronning and Bath, 1962; Hemingway, Parkins Fraser, 1986). The dried, shredded without was, however, generally less palatable.
200 mm diameter wafer-scale fabrication, metrology, and optical modeling results are reviewed for surface plasmon resonance (SPR) sensors based on 2-D metallic nano-dome nano-hole arrays (NHA's) as well 1-D photonic crystal a leaky-waveguide mode effect, with potential applications in label free sensing, enhanced Raman spectroscopy (SERS), surface-enhanced fluorescence (SEFS). Potential markets include micro-arrays medical diagnostics, forensic testing, environmental monitoring, food safety....
ABSTRACT Dried molassed sugar-beet pulp in Great Britain has for many years contained about 400 g molasses per kg dry matter (DM). Whilst this high concentration of might help to maximize palatability, places outside considerably lower amounts (100 300 g/kg) are normally added sugar beet. The relative costs depend on year-to-year fluctuations.
SUMMARY A molassed sugar beet product with 32% crude protein and containing added urea (8%), dicalcium phosphate, trace elements vitamins was evaluated in two experiments as a source for intensively-fed 100 kg British Friesian steers. Comparison made an equal amount of supplied mixture decorticated groundnut cottonseed meals. Both forms supplementation equally significantly increased live-weight gains improved food conversion ratios compared those recorded when the basal diet consisted...
SUMMARY A molassed sugar-beet product with added urea and dicalcium phosphate was evaluated as an energy protein source for housed lactating ewes. Comparisons were made a barley-vegetable barley-urea concentrate each formulated to supply approximately the same amount of crude protein. The overall performance ewes lambs given barley vegetable very significantly superior that receiving product. At 6 weeks after lambing had lost 57% (with singles) 23% twins) less weight their grown 28%...
Abstract Triangle tests were used to detect possible differences in the aroma of subcutaneous fat growing pigs receiving de‐oiled herring offal silage as a protein supplement at high (HS) and medium (MS) levels, i.e. levels 150 75 kg t −1 dry matter (DM), when compared with samples from matched controls. Tests carried out on slaughtered 60 90 kg. Statistically significant detected both feeding (HS MS) each slaughter weight (60 kg). Correct identification odd was 60% levels. At weight, there...
