    Notes: Portion-controlled menu items were heat processed in infrared and convection ovens to compare the effects of the heating methods upon nutrient retention. Product yields for hamburger and potatoes were significantly greater (P 〈 0.05) after convective heating; for tomatoes, after infrared heating. Nutrients analyzed foi selected menu items included: thiamin, riboflavin, vitamin C, β-carotene, seven fatty acids, 18 amino acids, ammonia, phosphorus, iron and sodium. Several significant differences between the heat processed samples were revealed. The riboflavin and vitamin A contents in hamburger and tomatoes, respectively, were significantly greater after infrared heating. The total amino acid contents were significantly greater after infrared heating for the hamburger patties and cod fillets.

    Behavioural responses of sablefish, Anoplopoma fimbria, to bait odour (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 46 (1995), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: A behavioural bioassay was used to determine the response threshold to squid extract of sablefish, Anoplopoma fimbria, held at three different feeding regimens. Sablefish responded to the odour of bait by changing swimming activity and turning behaviour. The response threshold to bait odour was influenced by both the amount of food eaten and the duration of food deprivation. The total concentration of amino acids in the bait extract was assumed to determine the response threshold as chemical fractionation studies have shown that this class of compounds is essential for the stimulatory capacities of food extracts. When fed to satiation (9.4% wet body weight) and tested after one day of food deprivation, the mean response threshold to total dissolved free amino acids was 4.4 × 10−8m (range=7.6 × 10−8 to 3.6 × 10−8m). When fed at 1.6-2.3% wet body weight, the threshold sensitivity had increased to a mean value of 1.8 × 10−10m (range=8.4 × 10−10 to 7.0 × 10−11m) after one day of food deprivation; after four days of deprivation, the sensitivity had increased even further to a mean value of 1.4 × 10−11m (range=1.6 × 10−10 to 1.4 × 10−12m). It was also apparent that the intensity of behavioural responses to the bait odour increased with both stimulus concentration and duration of food deprivation. These results suggest that sablefish intensify their search for prey under increased feeding motivation. The active space of a bait source was estimated from the threshold values obtained. Depending on state of food deprivation, rate of chemical release from the bait and the current velocity, maximum lengths of active space within which sablefish would exhibit food searching responses vary from 10 m to several km. Stock assessment based on catch data from baited gear will need techniques that take into account those factors influencing active space for food searching.

    The influence of light on egg buoyancy and hatching rate of the walleye pollock, Theragra chalcogramma (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 42 (1993), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Changes in buoyancy in fertilized bathypelagic eggs of the walleye pollock, Theragra chalcogramma, collected from Shelikof Strait in the Gulf of Alaska were measured under controlled laboratory conditions in density gradient columns from 90 h post–fertilization through hatching. Eggs were incubated at 6° C and exposed to either diel light or constant dark. Eggs held under diel light conditions became more dense than eggs under constant dark beginning 〈10 h after exposure to light and remained so until 12 h before hatching. Eggs held under constant dark then became more dense than those under diel light. Hatching of eggs under both conditions began at the same time but eggs under diel light showed a delayed hatching rate. Light–induced changes in egg density indicate the ability of walleye pollock eggs to respond to external stimuli and thereby alter their position in the water column in an ecologically meaningful way.

    Serological variability in Xanthomonas albilineans, causal agent of leaf scald disease of sugarcane (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Plant pathology 43 (1994), S. 0 
    Details
    ISSN: 1365-3059
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: The serological characteristics of 215 strains of Xanthomonas albilineans from 28 locations throughout the world were investigated. Three serovars were identified by using three sera prepared against strains from different locations. The same variation among strains was observed with different serological assays: immunofluorescence. dot-blot enzyme immunoassay and agglutination. Serovar I is the largest group and consists of strains from various geographic locations such as Australia. USA (Florida), Guadeloupe. India. Mauritius. Réunion and including South Africa. Serovar II contains only strains from Africa: Burkina Faso. Cameroon. Kenya. Ivory Coast. Serovar III is the smallest group and contains strains from Caribbean islands (Guadeloupe. Saint Kitts. Martinique). Oceania (Fiji) and Asia (Sri Lanka). This serological variability should be considered when serological techniques are applied for the diagnosis of leaf-scald disease of sugarcane.

    Stress-induced impairment of predator evasion and non-predator mortality in Pacific salmon (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Aquaculture research 26 (1995), S. 0 
    Details
    ISSN: 1365-2109
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: This study examined whether rapid recovery from stress-induced impairment in predator evasion, observed in previous studies on coho salmon, Oncorhynchus kisutch (Walbaum), was a general characteristic of different stocks of the same species and different species of Pacific salmon. We monitored stress-induced non-predator mortality, predator evasion and Cortisol concentrations of smolts of coho and spring Chinook, O. tshawytscha (Walbaum), after administration of standardized single and multiple handling stresses. Marked differences in the response to handling stress among stocks of coho and spring chinook smolts were evident, with recovery from impaired predator evasion occurring within 24 h of a 30-s handling stress for coho smolts and 24 h of a 1-min handling stress for spring chinook smolts. Differences in stress-induced non-predator mortality among stocks were also observed. The results point to the importance of screening hatchery salmonid stocks to assess differing capabilities of dealing with stress.

    Far-red light reflected from neighbouring vegetation promotes shoot elongation and accelerates flowering in spring barley plants (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Plant, cell & environment 17 (1994), S. 0 
    Details
    ISSN: 1365-3040
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Field experiments were conducted in St Paul, MN, USA, to test the hypothesis that early season declines in the red:far-red ratio (R:FR) associated with FR reflection from neighbouring leaves have a role in regulating barley development. Treatment plants were grown adjacent to densely sown border rows of barley. The borders functioned to reflect far-red (FR), which reduced R:FR within the treatment plant light environment without shading treatment plants. Barriers were set in the soil to minimize root interactions between treatment plants and borders. Treatment plants were spaced either 2 or 16 cm apart. The presence of borders significantly increased shoot leaf and internode lengths at both plant spacings. Leaf sheath length data suggest that interactions between 2 cm spaced treatment plants enhanced plant responsiveness to the presence of borders. Border treatments shortened the period of vegetative growth prior to initiation of main shoot floral primordia. Bordered plants formed fewer main shoot leaves, initiated internode elongation at a lower node, and had slightly earlier heading dates than unbordered controls. Leaf appearance rate was not influenced by border treatments. We conclude that barley shoot development is photomorphogenically modulated by R:FR. Early season shifts in R:FR could have a significant influence on shoot development given that barley has the capacity to detect and developmentally respond to declines in R:FR associated with FR reflection from neighbours.

    Notes: In March 1990 a pilot ultra-violet disinfection plant was installed at the sewage-treatment works in Bellozanne, Jersey. The pilot plant was set up to test the ability of the process to meet certain defined objectives and, ultimately, to enable the island authorities to satisfy stringent water quality objectives in the receiving waters of St Aubins Bay.The pilot study simulated an open channel installation using medium pressure ultra-violet lamps parallel to the direction of flow. The pilot plant was supplied by Trojan Technologies Inc.The pilot study met its objectives and confirmed the design parameters for a full-scale plant installation to follow.
