    Reduced-fat foods: the shopper’s viewpoint (2002)

    Notes: The inclusion of reduced-fat foods in the daily diet affords consumers the potential to reduce overall dietary fat. Nevertheless, despite an increased range of these food products throughout the market, there has remained a lack of widespread consumer acceptance. The aim of the study was therefore to understand why consumers choose or reject reduced-fat foods. Ninety consumers were interviewed by means of a qualitative approach within food retail outlets in the United Kingdom. Thematic content analysis indicated that uptake or rejection of these products is influenced by health concerns, ‘goodness of fit’ with individual dietary health strategies, the preferences of different household members, perceived sensory properties and scepticism towards these products. The results imply a need to explore and innovate ‘natural’ fat substitutes and to improve the sensory quality of reduced-fat products. Further research is required to determine how these foods are used within the household and incorporated within the overall diet. Policy must seek to restore consumer trust in reduced-fat food products and the food supply generally.

    Chemical Control of Carrot Fly (Psila rosae (F.)) on Parsnip (1973)

    Notes: During the past few years the recommended treatment for the control of carrot fly larvae on parsnip roots has been phorate granules applied ‘bow-wave’ at drilling at 31b active ingredient/acre (3·36 kg/ha), followed by two foliar sprays of chlorfenvinphos each at 2 lb a.i./acre (2·24 kg/ha). This has been the standard recommendation for the control of carrot fly on carrots grown on peat soils. In a trial in 1972 this treatment gave useful control of a heavy carrot fly infestation on parsnips on a peat soil in eastern England. Protection lasted for approximately 30 weeks, after which the amount of damage increased sharply. Of the granular insecticides tested in the same trial as alternatives to phorate at drillng, chlorfenvinphos was reasonably eifective, but neither disulfoton nor diazinon gave adequate control.Two sprays of chlorfenvinphos applied later in the season to previously untreated parsnips were ineffective.Parsnips in untreated plots were heavily attacked by both first and second generation larvae; 37–40 per cent of the untreated plants were actually killed by the first generation larvae.

    Susceptibilities of Carrot Cultivars to Carrot Fly (Psila rosae (F.) (1974)

    Notes: In 1972 a trial on susceptibility to carrot fly infestation was conducted on peat soil in East Anglia using 17 carrot cultivars sown on two dates one month apart. The only insecticide applied to the carrots was an aphicidal spray. The early-sown carrots were damaged by the first generation of larvae, but, by the second sampling date in October, there were no infestation differences between the two sowings. At harvest in December, significant differences in infestation levels occurred; these ranged from 82 per cent damaged roots for Amster-dammer Bak, 87 and 88 for two stocks of Royal Chantenay, to 97 per cent for Danvers 126. It is not yet clear whether the differences can be profitably exploited as an adjunct to other methods for controlling this pest.

    High-performance short-wavelength single quantum well pump lasers (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 63 (1988), S. 1246-1247

    ISSN: 1089-7550

    Topics: Physics
    Notes: Performance of graded-index separate-confinement heterostructure single quantum well lasers especially designed for cw optical-pumping applications is reported and is compared to that of conventional double-heterostructure devices. The quantum well devices have the advantage of lower threshold current, higher slope efficiency, and can be operated at longer cavity lengths, leading to lower diode-series resistance and reduced cooling requirements. Quantum wells of aluminum composition ranging from 6.7% to 12% and thicknesses of 12 and 20 nm were investigated. Useful lasing wavelengths between 780 and 820 nm were achieved.

    Efficiency enhancement in quantum well lasers via tailored doping profiles (1988)

    Notes: Reduced doping concentrations proximate to the active region in single quantum well (Al)GaAs lasers have been used to improve the external quantum efficiency. A substantial enhancement is observed in a structure in which, by design, the mode overlap with the doped confining regions is large. For a structure in which the mode is tightly confined, doping modifications have no measurable effect.

    Notes: cw power conversion efficiencies of 57% have been obtained on uncoated diode lasers emitting nearly 300 mW per facet. This performance is achieved by using a low-resistance graded index separate confinement single quantum well AlGaAs/GaAs structure with high (84%) differential quantum efficiency and low threshold current.

    Van der Waals bonding of GaAs on Pd leads to a permanent, solid-phase-topotaxial, metallurgical bond (1991)
    Woodbury, NY : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Various forms of wafer bonding have now emerged as a serious competitor to heteroepitaxy for optoelectronic integration of dissimilar semiconductor materials. Among the types of wafer bonding, perhaps the most flexible is that which employs free-standing III–V films as created by epitaxial liftoff. For some purposes, weak Van der Waals forces provide an adequate bond between the native oxides of the III–V film and its new substrate. If the substrate is coated by palladium however, a low temperature solid-phase-topotaxial reaction occurs, producing oriented Pd4GaAs under the GaAs film. In effect, the topotaxy comes about through mechanical contact alone. The resulting metallurgical bond is an ohmic contact, a thermal contact and a robust, permanent, adherent contact.

    Notes: We have fabricated the first heterojunction phototransistor (HPT) on InP-on-Si. These phototransistors, based on the InP/GaInAs heterojunction, have optical gains as high as 125 A/W at 1300 nm and dark currents as low as 300 pA, for a 48×64 μm HPT. The bandwidth was determined from impulse photoresponse measurements to be 4.4 GHz. The intrinsic bandwidth was estimated from the zero bias capacitance (0.2 pf) to be as high as 16 GHz.
