Published 1996Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The effect of applying an electric field across a quasi-phase-matched frequency doubling lithium tantalate waveguide has been investigated. The waveguide was fabricated by a two-stage ion exchange process in pyrophosphoric acid. An electric field of 2 kV/mm was found to shift the phase matching wavelength by 0.05 nm. It is estimated that more optimized waveguides could produce wavelength shifts of ±4 nm for an applied electric field of ±20 kV/mm and could compensate for temperature variations of ±67 °C. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

To assess the value of impedance cardiography in pregnancy, simultaneous measurements of cardiae output were made with impedance and thermodilution techniques in 10 patients who required pulmonary artery catheterization. The methods correlated poorly (r=0·17). The discrepancy between methods was particularly pronounced in hypertensive patients. Impedance cardiography does not measure cardiac output accurately in hypertensive pregnant women.Type of Medium: Electronic ResourceURL: -

ISSN: 1471-4159Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Abstract: Lactate dehydrogenase and aldolase activity were reduced in lateral gastrocnemius muscle from two mouse mutants, A2G-adr and 129Re-dy, with abnormal muscle function. The activities of both of these enzymes were significantly reduced in the lateral gastrocnemius muscle from the A2G-adr mice at ages varying from 2 weeks to 32 weeks, whereas the activities in the soleus, heart, liver, and brain were the same as in the control animals. The lactate dehydrogenase isoenzymes in the lateral gastrocnemius and soleus muscles from the A2G mice were quantified, and although those of the soleus were comparable in mutant and control muscle, the lateral gastrocnemius from the adr mutant had reduced activity of LDH 5 and increased activities of the other four isoenzymes. The findings suggest that the adr mutation is expressed in the white (Type II) muscle fibres and not in the red (Type I) fibres or in any of the organs studied. It is suggested that the initiation of differentiation into Type II fibres from the embryonic form is absent or delayed in the A2G mutant. The reduced activities of lactate dehydrogenase and aldolase in 129Re-dy muscle confirm the findings of other workers.Type of Medium: Electronic ResourceURL: -

ISSN: 1750-3841Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionProcess Engineering, Biotechnology, Nutrition TechnologyNotes: Radioactive acetic anhydride was used to label casein, isinglass, egg white, and a pectic enzyme complex. The pectic enzyme was added to three different grape juices which were fermented, bentonite fined and filtered in an approximation of industrial practice. Three wines were fined using isinglass or egg white (red wines) or casein (white wines) applied at three rates each, and finished as above. Residual amounts of each additive were determined by scintillation counting of samples taken at each step. All of the pectic enzyme remained in the finished wines. Residual fining agents decreased with the application rate to levels showing much variation in the red wines and less in the whites.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Fourteen representative visible light-cured composite materials, including a total of 29 shades, have been examined for sensitivity to ambient light. The assessment was based upon a procedure recommended in an International Standard (ISO/DIS 4049). All but four of the 29 formulations exceeded the critical working time of 60 s when exposed to ambient illumination of 20 klx. These four composite resins exhibited working times greater than 60 s under 10 klx illumination, and the maximum working time observed at 10 klx was 227 s. These data confirm the finite working time of light-cured resins under clinical lighting conditions.Type of Medium: Electronic ResourceURL: -

Published 2005Staff ViewISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: summary The objectives of this study were to investigate the structural characteristics of orthodontic polyurethane elastomeric modules and their changes produced by mechanical and chemical ageing. Three products were tested (Generation II, Dentaurum, Alastic). For each product four groups of modules were studied under the following conditions: as-received (A0); after 3 weeks stretching at 50% elongation in air (B0); after 3 weeks immersion in an ethanol/water solution (3:1 v/v) to induce accelerated ageing (A1); and after 3 weeks immersion in the ethanol/water solution at 50% elongation, as above (B1). The chains and the solution extracts were characterized by micro-MIR FTIR spectroscopy. Specimens of group B0 exhibited changes in peak intensities relative to the control group (A0), attributed to molecular orientation of poly (methylene glycol) soft segments and chain extenders such as butanediol. Moreover, group B0 showed differences in the ω(CH2)b peak at 1364 cm−1, attributed to oxidative degradation of α-methylene groups by formation of ester, carboxylic acid or aldehyde groups due to hydrogen abstraction. Comparison of A1 and B1 groups with the controls (A0, B0) showed no major differences between their respective spectra, apart from the loss of the 1639 cm−1 peak attributed to ethylene NN bis (stearamide) wax. However, comparison of the spectra of the extracts from the elongated modules with the extracts of the controls revealed differences in the concentration of alcohol and alkene groups. The structural changes identified were the same in all the products tested and may indicate degradation mechanisms that could potentially hold intraorally.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The rheological behaviour of six setting carboxylate cements was studied by capillary techniques in the shear rate of 0.65–65 s−1 and the cements were found to behave as power law fluids. All cements became dilatant as setting progressed and the kinetics of apparent viscosity increase, were found to follow an exponential function of time, exp (mt), with m ⋍ 0.5.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The rheological properties of two glass ionomer cements, ASPA and Fuji have been investigated. The viscosities of the liquid components of these systems have been found to be Newtonian up to a shear rate of 140 s−1 with values of 0.80 N m−2 s for ASPA and 1.8 N m−2 for Fuji. Capillary viscometry techniques have been employed to study the rheological changes accompanying setting. Both cements appear to behave as power law fluids, becoming progressively dilatant as setting proceeds. The apparent viscosities of the two systems are approximately equivalent displaying values of the order of 50 N m-2 s, at a shear rate of unity shortly after mixing.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Dental elastomeric impression materials of different consistencies, representing addition and condensation silicones, polysulphides and a polyether, were studied to determine their mechanical properties in terms of tearing energy, tensile properties and modulus determined at high strain rates. Whilst the polysulphides had the greatest resistance to tearing, they were more extensible, had lower moduli of elasticity and lower tensile strengths than the silicones. The polyether resembled the silicones in many respects.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The rheological properties of two commercial resin systems, Isopast and Cosmic, were studied in the shear rate range 0.65-65 s−1 by capillary techniques. Isopast represents a low inorganic filled composite, whereas Cosmic is a conventionally filled system whose resin matrix resembles that of Isopast. All components of both systems obeyed power law dependence of shear stress as a function of shear rate according to the relation In τ= In K + n In γ; values of n for Cosmic catalyst and paste and Isopast paste were of the order of 0.6 whereas Isopast catalyst was of the order of 0.3. Setting systems obeyed a power law relationship during the working time with an exponent n≃0.7-1.0. Accordingly the systems appear pseudoplastic in component form and slightly pseudoplastic to near Newtonian after mixing.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: A clinically realistic in vitro study was performed to determine the best method for smoothing trimmed surfaces of seven composite restorative materials. Soflex discs produced the smoothest surface, and little advantage appeared to be gained by prior smoothing of the surface with stones or points. A polishing paste, even when used with intermediate finishing agents, produced a rougher surface than that left by the discs.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: A cone-plate viscometer was employed for studying the rheological characteristics of certain unfilled resins and etching gels. Of these, BIS-GMA monomer and its diluted mixtures exhibited Newtonian, dilatant and thixotropic behaviour depending on the shear rate. Other unfilled resins also exhibited various types of behaviour. At high shear rates reproducible hysteresis loops were obtained for etching gels which may be useful in characterization.Type of Medium: Electronic ResourceURL: -
