Published 2003Staff ViewISSN: 1525-1314Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: GeosciencesNotes: Coesite relics were discovered as inclusions in clinopyroxene in eclogite and as inclusions in zircon in felsic and pelitic gneisses from Higher Himalayan Crystalline rocks in the upper Kaghan Valley, north-west Himalaya. The metamorphic peak conditions of the coesite-bearing eclogites are estimated to be 27–32 kbar and 700–770 °C, using garnet–pyroxene–phengite geobarometry and garnet–pyroxene geothermometry, respectively. Cathodoluminescence (CL) and backscattered electron (BSE) imaging distinguished three different domains in zircon: inner detrital core, widely spaced euhedral oscillatory zones, and thin, broadly zoned outermost rims. Each zircon domain contains a characteristic suite of micrometre-sized mineral inclusions which were identified by in situ laser Raman microspectroscopy. Core and mantle domains contain quartz, apatite, plagioclase, muscovite and rutile. In contrast, the rim domains contain coesite and minor muscovite. Quartz inclusions were identified in all coesite-bearing zircon grains, but not coexisting with coesite in the same growth domain (rim domain). 206Pb/238U zircon ages reveal that the quartz-bearing mantle domains and the coesite-bearing rim were formed at c. 50 Ma and 46.2 ± 0.7 Ma, respectively. These facts demonstrate that the continental materials were buried to 100 km within 7–9 Myr after initiation of the India–Asia collision (palaeomagnetic data from the Indian oceanic floor supports an initial India-Asia contact at 55–53 Ma). Combination of the sinking rate of 1.1–1.4 cm year−1 with Indian plate velocity of 4.5 cm year−1 suggests that the Indian continent subducted to about 100 km depth at an average subduction angle of 14–19°.Type of Medium: Electronic ResourceURL: -

Published 1991Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: High-efficiency InGaAlP surface emission light emitting diodes (LEDs) have been successfully fabricated. Newly designed double-heterostructure LEDs with a GaAlAs current spreading layer were employed to expand the light emission area, which is necessary to take out the light efficiently. The external quantum efficiency was 1.5% at 620 nm orange light for an In0.5 (Ga0.8Al0.2)0.5P active layer LED. This LED is five times more efficient at 620 nm than that of the GaAlAs and GaAsP LEDs. 563 nm green electroluminescence, which is the shortest wavelength ever reported for InGaAlP LEDs, was also achieved with an In0.5(Ga0.5Al0.5)0.5P active layer.Type of Medium: Electronic ResourceURL: -

Published 1997Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Amorphous SiO2 was deposited on three single-crystalline substrates: alumina, CaF2, and hydrogen-terminated silicon, by chemical vapor deposition (CVD) using tetraethoxysilane (TEOS) and ozone (O3). The deposited layers were then examined by using atomic force microscopy (AFM). For deposition times of 3, 8, 15, and 180 s, the film thickness ranged from less than 2.4 to 150 nm, respectively. Comparison of the surface roughness with the film thickness, as determined independently by ellipsometry, indicated that the thinnest film formed on the silicon surface (2.4 nm) was continuous. During film formation, for all three substrates, the surface roughness increased initially, reached a maximum, and then decreased. Surprisingly, the surface became smooth (within the resolution of 0.2 nm of our AFM). For the silicon substrate, this smoothing occurred between 3 and 8 s, which corresponds to 2.4 and 6.4 nm of deposition, respectively. Furthermore, just before the smoothing started, the surface of the deposited film contained protuberances, 1.6 nm high and 16 nm×16 nm in area. This indicates that smooth film of a few tens angstroms in thickness can form on the silicon. The smoothing of the protuberances occurred between 3 and 8 s for the CaF2 substrate, and between 15 to 180 s for the alumina substrate. The initial formation of a rough surface followed by smoothing is likely to be inherent in TEOS/O3 CVD systems, irrespective of substrate type. Surface-tension-induced flows of the surface, which has liquidlike properties, is a plausible mechanism. © 1997 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Heterobarrier blocking structure InGaAlP visible light laser diodes employing a thin active layer (0.04 μm) and asymmetry coatings have been fabricated. The high light-output power operation with this heterobarrier blocking structure was investigated. The light-output power versus cw current curve was linear up to 43 mW and a maximum light output power of 51 mW was obtained. A high-power operation such as 20 mW was maintained at 40 °C. Stable oscillation in the fundamental transverse mode was obtained up to 30 mW. These results show that this heterobarrier blocking structure supplies a sufficient current confinement effect even under a high-light output power operation.Type of Medium: Electronic ResourceURL: -

Published 1993Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: A new GaAs laser diode employing InGaAlP for the cladding layer has been successfully fabricated. A large band-gap difference between the GaAs active and InGaAlP cladding layers reduced the electron overflow, which drastically improved the temperature characteristics. The highest temperature continuous wave operation of 212 °C was obtained. A large characteristic temperature, T0 of 190 K was maintained up to 140 °C. Any significant problem due to a heterointerface of GaAs/InGaAlP including high Al composition was not observed through the laser characteristics.Type of Medium: Electronic ResourceURL: -

The devices are optically pumped and employ a novel cavity design using GaAs/AlAs quarter-wavelength stacks for one mirror. The characteristic temperature T0 of the device increases from 42 K at room temperature to 81 K at temperatures above 80 °C as the gain peak moves into resonance with the longer wavelength cavity mode.Type of Medium: Electronic ResourceURL: -

Measurements of the dielectric capacitance, in the frequency range 1 kHz to 100 kHz, were made on soybean oil heated at several temperatures (180, 200, 220, and 240 °C) for a few d. Frequency dependence was also measured between 50 Hz and 30 MHz. The dielectric constant of the soybean oil increased with increase in the heating time, and was well correlated with acid value, density, and relative viscosity. Our equipment for measuring capacitance would be available for real time and continuous evaluation of frying oil quality in the food industry.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1365-2109Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: In order to confirm the suitability of cholestane (CLS) for determination of lipid digestibilities in prawn, Marsupenaeus japonicus, the movements of dietary triacylglycerol and CLS in its digestive tract were examined. In this present study, the double labelling method was evaluated using [3H]-triolein and [14C]-CLS, which was chemically synthesized from [14C]-cholesterol. Three test diets containing different levels of lipid (0, 80 and 100 g kg−1 dry diet) with [3H]-triolein (150 MBq kg−1 diet) and [14C]-CLS (150 MBq kg−1 diet) were prepared. One prawn was stocked into a 1 L Erlenmeyer flask containing seawater at 25 °C. After the prawns had been fed on 1% of body weight of the labelled diets, they were transferred to another Erlenmeyer flask and held for 1, 3, 6, 12, 24, 36 and 96 h after feeding. At every collection time, radioactivity of the hemolymph, stomach, midgut gland, midgut, hindgut, muscle and faeces was determined by liquid scintillation counter. All analyses were performed in triplicate with one prawn per collection time per test diet.In the prawns administrated labelled diets, over 75% of the total radioactivity was recovered in faeces at 96 h after feeding. The ratio of [3H] to [14C] in the gastrointestinal tract of the prawn did not fluctuate for 96 h after feeding. Thus, triolein and CLS were shown to move at the same speed in the gastrointestinal tract. The results demonstrate that CLS satisfied one requisite for markers in the digestibility measurement of dietary lipids in the prawn.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2109Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Artificial microdiets have been prepared for nutritional studies and for replacing live feeds in seed production of fish and crustaceans. Much knowledge has been accumulated on microdiets and their dietary values for several species. Total replacement of live feeds with microdiets has been accomplished in prawns, and optimum dietary levels of several nutrients have been reported for prawns. These studies have demonstrated specific nutrient requirements of larval fishes for some phospholipids and of crustaceans for both sterols and phospholipids. However, the quantitative requirements of larval aquatic animals for nutrients are still obscure, possibly because of lack of information on feed intake. From a nutritional viewpoint, optimum dietary levels of nutrients in microdiets determined without measuring net feed intake may be regarded as a conclusion without universal validity. This article proposes methods for the estimation of feed intake in crustaceans and fish fed microdiets, together with a brief review of microdiets and their nutritive values for aquatic animals. First, the methods for measurement of fat-soluble nutrients, cholesterol and fatty acids, using 5α-cholestane as an inert marker, were evaluated in juvenile prawns Macrobrachium rosenbergii and Penaeus japonicus and tilapia Oreochromis niloticus. Secondly, a new method for the measurement of feed intake using double markers, 5α-cholestane and dotriacontane, was evaluated using juvenile P. japonicus and larval red sea bream Pagrus major as test animals. The significance of these methods in assessing the nutrient requirements of larval aquatic animals is discussed.Type of Medium: Electronic ResourceURL: -

Published 2002Staff ViewISSN: 1365-2109Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: The requirements of juvenile prawn, Marsupenaeus japonicus (Bate), 0.79 g initial body weight, for essential amino acids (EAA) were evaluated based on the daily increase of each EAA in the whole body when the prawn was maintained on a diet with a high nutritive value (a casein-squid protein-based diet). The quantities of each EAA needed daily for growth and maintenance of prawn are conceived to correspond to the daily requirements of this prawn species for EAA. Therefore, these requirement values of respective EAA should be supplied from dietary proteins. To determine these values, protein and amino acids of the whole body of the prawn were quantified before and after feeding experiments, and the quantities of respective EAA needed to meet the requirements were estimated based on the EAA profile of the whole body protein of prawn. As a result, the contents of EAA in dietary proteins (%) needed to meet the requirements of the prawn for EAA were assessed to be: threonine (2.3), methionine (1.3), valine (2.4), isoleucine (2.3), leucine (3.4), phenylalanine (2.6), lysine (3.2), histidine (1.1), arginine (2.9) and tryptophan (0.6), respectively, when the prawn are fed 50% protein diet with 90% protein digestibility at a ration size of 2% (% of body weight).Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2109Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Three experiments were conducted to elucidate the effects of ursodeoxycholic acid (UDCA) on growth performance and digestive enzyme activities of Japanese flounder Paralichthys olivaceus (Temminck & Schlegel) juveniles and larvae. In experiment 1 (growth study), duplicate groups of juveniles of about 7 g initial body weight were fed a UDCA diet (containing 0.025% UDCA) and a control diet (without UDCA) to apparent satiation twice a day for 6 weeks at 18–21 °C. In experiment 2 (enzyme study), triplicate groups of juveniles (7 g) were also fed the UDCA and control diets for 6 weeks under similar feeding and water management conditions to those for the growth study, digestive organs were collected every 2 weeks and their enzyme (α-amylase, lipase and protease) activities were assayed. In experiment 3, duplicate groups of 48-day-old larvae were fed two test microdiets (UDCA and control diets) for 30 min and assayed for enzyme activities 6, 12, 24, 36 and 48 h after a single feeding in the morning. The weight gain and feed conversion efficiency of the juveniles fed the UDCA diet in the growth study did not show any significant difference compared to juveniles fed the control diet. Total lipids, neutral lipids and triglycerides of the whole body and apparent body retention (%) of dietary lipids were notably higher (P 〈 0.05) in the UDCA group than the control. In the juveniles fed the UDCA diet, the activities of α-amylase and protease did not increase with holding time compared to the control diet. Lipase activity of the juveniles fed the UDCA diet was significantly higher than those fed the control diet. By contrast, the activities of α-amylase, lipase and protease of the larvae at 6, 12, 24, 36 and 48 h after final feeding did not show any difference between the dietary groups. These results suggest that UDCA may have an important role in lipid assimilation by increasing enzyme activity of the juvenile Japanese flounder, but there are few effects on growth performance of the juveniles and digestive enzyme activities of the larvae.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2109Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: The dietary effect of arachidonic acid (20:4n-6, AA) on the composition of the head and the body, and on the pigmentation of Japanese flounder, Paralichthys olivaceus (T. & S.), was studied by means of microbound diets. Increasing levels of this essential fatty acid produced higher growth and pigmentation success in juveniles after 45 days of feeding. The role played by AA in the composition of phosphatidylinositol and eicosanoid synthesis is discussed in relation to the normal function of the neural system and the production of hormones involved in the metamorphosis and pigmentation of flatfish.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2109Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: The energy budget of the Japanese flounder Paralichthys olivaceus (Temminck & Schlegel) larvae fed enriched (EA) and non-enriched (NEA) Artemia nauplii was determined by equating energy intake (EI) with the summation of energy channelled to faeces (F), metabolism (M), excretion (U) and growth (G). Larvae (21 days post hatching, 2.2 mg mean wet wt) were reared in six 80-L circular tanks with three replicates of 160 larvae per tank and fed EA and NEA for 20 days. EI was calculated from the energy content of consumed nauplii, M from the summation of energy for routine, feeding and active metabolisms, U from ammonia excretion and G from energy gained based on weight gain, while F was the difference between EI and the total of other components. The heat increment of larvae was calculated from the difference of O2 consumption at post-prandial and routine conditions. Except for G and F, variables were correlated to the dry body weight (W) of larvae in a power function: Y=aWb. Coefficients a and b were estimated by regression after a logarithmic transformation of the raw data. Overall, growth and survival rates of the larvae fed EA were higher than those fed NEA. For a larval flounder growing from 2 to 20 mg wet wt, the ingested energy was partitioned as follows: 22.8% to faecal loss, 38.3% to metabolism, 1.5% to urinary loss and 37.4% to growth for the EA group, whereas 35.4% to faecal loss, 28.4% to metabolism, 1.3% to urinary loss and 34.9% to growth for the NEA group. Gross conversion and assimilation efficiencies were higher, but the net conversion efficiency was lower in EA-fed larvae than NEA-fed larvae. This study suggests that the higher growth and survival rates of the EA-fed group compared with the NEA-fed group were attributed to their higher intake of essential fatty acids, higher metabolism and lower energy loss of faeces.Type of Medium: Electronic ResourceURL: -

The Tg was 178–187 K and decreased with increasing NaCl content from 1:9 to 6:4 NaCl:BSA. The specific heat change (ΔCp*, J/((g BSA)K)) at Tg increased as the weight ratio increased from 1:9 to 5:5 NaCl:BSA, as did the change in calculated unfrozen water (UFW). The UFW was also correlated with the amount of NaCl in the glassy region with a correlation coefficient of approx. 6 (mol H2O)/ (mol NaCl), which is comparable to the hydration number of Na+. These results suggest that UFW could contribute to the ΔC at Tg of the BSA-water system.Type of Medium: Electronic ResourceURL:
