    EFFECTS OF PEELING METHODS ON THE NUTRITIVE CONTENT OF WHOLE CANNED CHICO III TOMATOES (1978)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 43 (1978), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The purpose of this investigation was to determine the effect of peeling method (hot water, lye, or liquid N2) on the nutrient composition of canned tomatoes. The titratable acidity was slightly lower in lye-peeled than in water- or N2 -peeled tomatoes, and niacin was a little lower in water-peeled than in lye- or N2-peeled tomatoes. There were no differences in moisture, pH °Brix, ash, fat, fiber, iron, calcium, protein, ascorbic acid, β-carotene, thiamine, riboflavin, total carbohydrate, or caloric value which could be attributed to peeling method.

    The Utilization of Carbohydrate and Nitrogen Reserves by Taxus During Its Spring Growth Period (1971)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 24 (1971), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The spring growth and the utilization of carbohydrate and nitrogen reserves in this growth was studied in Taxus media cv. Hicksii plants 0, 2, 4 and 6 weeks after the plants started growing in the spring. The effect of nitrogen applied the previous season on the storage and utilization of the carbohydrate and nitrogen reserves during spring growth was determined. The plants were separated into buds (all new growth), stems, needles (those produced the previous season) and roots and analyzed for changes in total nitrogen, basic and non-basic amino acids, total available carbohydrate, sugars, hemicelluloses, organic acids and chlorophyll.The bulk of the soluble nitrogen reserves were stored as arginine in the stems and old needles. With the onset of spring growth, arginine nitrogen was converted to other amino acids which accumulated in the new growth (buds). The roots, stems and needles of plants grown under high nitrogen levels always contained more total nitrogen than those grown under low nitrogen levels.The bulk of the carbohydrate reserves were stored as hemicelluloses. The plants grown under high nitrogen levels utilized the bulk of the carbohydrate reserves from the roots and smaller amounts from the stems and old needles, while plants grown under low nitrogen levels used only the reserves in the roots. In the low nitrogen plants, carbohydrates accumulated in the needles and stems.Both the carbohydrate and nitrogen reserves were important in the dry weight increase due to spring growth. However, the nitrogen reserves were the limiting factor and the high nitrogen plants grew twice as much, produced more chlorophyll, and utilized more nitrogen and carbohydrate reserve in spring growth than low nitrogen plants. The additional chlorophyll allowed the production of more carbohydrates and these additional carbohydrates were used in increased growth rates, while in the low nitrogen plants the carbohydrate produced was less and accumulated within the plant.

    The In Vitro Growth Response of Giardia Trophozoites from the Rabbit (1971)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 18 (1971), S. 0

    Topics: Biology
    Notes: SYNOPSIS. A visual technic has been developed for determining concentration of Giardia trophozoites in culture tubes. Such a technic is desirable because the nature of Giardia growth makes routine enumeration of these organisms by hemocytometer or electronic cell counter expensive in both time and material. The visual method of counting Giardia trophozoites was correlated with counts of the same suspensions of organisms using an electronic particle counter.As a part of the correlation, the growth response, as measured by electronic cell counter, was established for 8 primary axenic cultures of Giardia trophozoites from the rabbit. The average starting number of organisms was 3.7 ± 0.6 × 103 per ml, the average number of organisms at the peak of logarithmic growth was 1.78 ± 0.2 × 105 per ml, and the generation time was 18.1 ± 1.6 hr. These data are compared with the available literature data quantitating Giardia growth.

    Notes: [Auszug] Cosmic rays provide information on the composition and structure of the Galaxy. Recent measurements suggest that the isotopic composition at the cosmic-ray sources is similar to that of the Solar System and that cosmic-ray acceleration follows nucleosynthesis after a considerable delay. Cosmic rays ...

    Evergreen Foliage Contributions to the Spring Growth of Taxus (1971)

    Notes: Taxus media cv. Hicksii plants were grown one season under a low and high level of nitrogen fertilization. Before growth in the spring the plants were divided into two groups, one of which was defoliated and the other left intact. The growth and spring utilization of the nitrogen and carbohydrate reserves of defoliated plants were compared to the intact plants 0, 2, 4 and 6 weeks after growth started in the spring. The plants were separated into buds (all new growth), roots and stems and analyzed for changes in total nitrogen, basic and non-basic amino acids, hemicelluloses, soluble sugars, organic acids and chlorophyll.The older evergreen needles from plants grown under low nitrogen levels contain 20 % of the carbohydrate and 24% of the nitrogen used in spring growth. The needles from plants grown under high nitrogen levels contained 56% of the carbohydrate and 49% of the nitrogen used in spring growth. Removal of the old needles before spring growth removed this nitrogen and carbohydrate reserve and reduced the total plant chlorophyll content after 6 weeks of growth to 50% of that found in intact plants, with the result that defoliated plants did not show a growth response to nitrogen. Amino acids accumulated in the stems and buds of defoliated plants as carbohydrates became limiting. The defoliated plants removed 25% more available carbohydrates from the roots and stems than intact plants and their buds contained 50% less available carbohydrates.Plants without old needles showed similar growth rates under low and high nitrogen regimes and produced 33% of the dry weight of intact plants grown under high nitrogen levels and 66% of the dry weight of intact plants grown under low nitrogen levels.The old needles of taxus plants contain substantial amounts of reserve nitrogen and carbohydrate and these needles greatly influence the extent and rapidness of growth in the spring. When the needles are removed, the other tissues can supply an adequate amount of nitrogen but the carbohydrate supply becomes limiting for spring growth.
