    Aerosol lithium concentration data from the Indian and Pacific ocean (2022)
    PANGAEA
    Details
    Publication Date: 2023-03-04
    Description: A total of 125 aerosol samples were analysed for their lithium concentrations and deposition flux. Daily aerosol samples were collected from the Pacific Ocean during CLIVAR-CO2 Repeat Hydrography Sections P16 and P2. The P16 section follows 150°-152°W and was divided into two legs, a southern leg from 17°S to 71°S in January-February 2005, and a northern leg from 16°S to 56°N in February-March 2006. CLIVAR-CO2 section P2 from Japan to San Diego, along 30°N, was visited in June-August 2004. The aerosol data from both CLIVAR-CO2 sections include aerosol lithium concentration measured following digestion in HF:HNO3:HCl mixture and corrected for sea-salt contributions (Li xs total), the P16 data also includes aerosol lithium extracted with ultrapure deionised water (≥18 MΩ) by pulling 100 mL of deionised water within ten seconds through the filter (Li xs MQ). Aerosol lithium deposition flux was calculated based on the local rain rate.

    PANGAEA
    Details
    Publication Date: 2024-04-19
    Description: A total of 603 seawater samples and 125 aerosol samples were analysed for their lithium concentrations. The seawater samples were collected during eight research expeditions. All seawater lithium concentrations were normalised to TEOS-10 absolute salinity of 35 g/kg. Most seawater samples were collected using Niskin bottles and filtered using 0.22 µm filters. Exceptions are samples UW1-UW26 that were collected from the underway water system of RV Kilo Moana during cruise CDisK-IV, and surface water samples from the Red Sea that were collected using a bucket lowered from the deck of a container ship. Samples from cruises SOE09, RS2015 and RS2018 were not filtered. The seawater samples were collected during the following cruises: CDisK-IV from Hawaii to Alaska in 01-30 August 2017; SN105 from Goa to Mauritius, samples collected during 7-16 December 2015; RS2015 from the Bay of Bengal to the Mediterranean Sea, samples collected during 27 December 2015 to 3 January 2016; RS2018 from the Bay of Bengal to the Mediterranean Sea, samples collected during 23-31 March 2018; SOE09 in the Indian sector of the Southern Ocean in 12 January - 21 February 2017; JR274 in the Atlantic sector of the Southern Ocean between 9 January and 12 February 2013; D357 and JC068 sailed from South Africa to South America, mostly along 40°S, cruise D357 in 18 October – 22 November 2010, and cruise JC068 in 24 December 2011 – 27 January 2011.

    ALCA — automated local area networks configuration aid (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Expert systems 8 (1991), S. 0 
    Details
    ISSN: 1468-0394
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Computer Science
    Notes: Abstract: Solving the customer's LAN/WAN interconnect problem is difficult because of the need to explore many possible configurations (e.g. bridging/routing, packet/channels) and then to choose the best configuration using economic, performance and other criteria. The rapid introduction of new standards, protocols and products to the networking field brings additional complications to the solution and can cause confusion when configuring a network. ALCA is intended to generate all feasible LAN/WAN configuration possibilities automatically and to pick the most appropriate solution to solve the customer's problem, while specifically addressing open systems interconnection (OSI) standards. Matching communications protocols while searching all possible configurations is notoriously slow even on a computer. We show how the search speed can be significantly improved by using expert system knowledge compilation, a computer-aided software engineering (CASE) technique. ALCA is based on a centrally updated knowledge base of various local area networking products and their interconnect possibilities. ALCA also allows querying to find out protocol interfaces supported by a particular product/service. Finally, it includes a graphic user interface and context-sensitive menus to reduce user information load. ALCA is intended to be used by the field personnel involved in pre-sales support, by the data communication product managers, and as an educational tool for novice communication product managers.

    Development of a New Cytoplasmic Male-Sterility System in Brassica juncea through Wide Hybridization (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Plant breeding 112 (1994), S. 0 
    Details
    ISSN: 1439-0523
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: A new cytoplasmic male-sterility system was developed in an oilseed Brassica, viz. B. juncea var. ‘Pusa Bold’ with the cytoplasmic background of a wild species, Diplotaxis siifolia, obtained through wide hybridization. The synthetic alloploid (D. siifolia×B. juncea: 2n = 56, D3D3AABB) was repeatedly backcrossed to B. juncea to achieve cytoplasmic substitution. The CMS plants resembled the cultivar in growth and morphology. The flowers had narrow sepals and petals and short, shrivelled anthers which failed to dehisce. The meiotic process appeared to be normal. The microspores degenerated at an early stage after tetrad formation. Female fertility in the CMS plants was as good as in the cultivar. Female transmission of sterility confirmed it to be cytoplasmically encoded.

    Notes: Abstract This review of high-T c superconducting thin-film processing focuses on the developments in thin-film deposition technologies since 1987. The common deposition processes are described with reference to their effects on superconductor film performance. A comparative evaluation of the potential of the technologies is also given. The development of multilayers and heterostructures is an important requirement for future device applications and is also described. The latest results of the deposition of novel superconducting materials and deposition on uncommon substrates are discussed. The outlook on some imminent topics of future development in process technologies for high-T c superconducting thin films is discussed.

    Rapid and efficient plant regeneration from hypocotyl protoplasts of Brassica carinata (1992)
    Springer
    Plant cell reports 11 (1992), S. 159-162 
    Details
    ISSN: 1432-203X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Protoplasts were isolated from hypocotyls of 7-d-old seedlings of three genotypes of Brassica carinata after enzymatic digestion in cellulase R-10 (0.5%) and pectolyase Y-23 (0.025%). The protoplasts were stabilized with 0.4 M mannitol used as osmoticum, and were cultured in darkness in Kao's liquid medium containing 0.4 M glucose and the growth regulators 2,4-D (1.0 mg/l), NAA (0.1 mg/l) and zeatin riboside (0.5 mg/l). Protoplasts were transferred to 16 h photoperiod conditions after 3 d of dark culture, and the medium was diluted to reduce the osmoticum on the seventh and tenth days of culture. Microcolonies were thus obtained which, upon transfer to MS agarose medium with 2,4-D (0.1 mg/l), BAP (1 mg/l) and 0.1 M sucrose, proliferated further to produce callus clumps. The plating efficiency of the three genotypes varied from 1 to 2%. Calli 2–3 mm in diameter were transferred to MS agarose plates with zeatin (2 mg/l) where they produced shoot buds and shoots with frequencies ranging from 22.5 to 74.2% for the three genotypes. The shoots were rooted in medium with IBA (1 mg/l) and were then established in soil. The time required for protoplast to plant development was 8 to 10 weeks.

    Description / Table of Contents: Zusammenfassung Das Voranschreiten von Hochtemperaturprozessen wird im allgemeinen als Funktion der Abhängigkeit des Konversionsgrades (α) von der Zeit (t) beschrieben. Vorliegende Arbeit umreißt ein Verfahren zur Anwendung vonα-t-Diagrammen für eine vergleichende Einschätzung von Produktivität und Energieanforderungen für ein Testsystem auf der Basis einiger vereinfachender Annahmen. Man nimmt an, daß der Durchsatz umgekehrt proportional zur Reaktionszeit ist, wie z.B. im Falle von diskontinuierlichen Reaktoren und Pfropfenströmungsreaktoren. Weiterhin wird angenommen, daß der Energieverbrauch eine einfache Funktion der Prozeßtemperatur ist. Das umrissene Prinzip wird anhand einiger Labordaten über die Reduktion von Eisenoxid durch Kohle illustriert.
    Notes: Abstract The progress of high temperature processes is generally described in terms of variation of the degree of conversion (α) with time (t). The present paper outlines a procedure for making use ofα-t plots for comparative assessment of productivity and energy requirements for a test system with respect to a reference, on the basis of some simplifying assumptions. It is assumed that the throughput is inversely proportional to reaction time as in the case of batch reactors and plug flow reactors. It is also assumed that the energy requirement is a simple function of process temperature. The principles outlined is illustrated with reference to some laboratory data for reduction of iron oxide by coal.

    Notes: Summary Synthetic alloploid Brassica oxyrrhina (2n = 18, OO) x B. campestris (2n = 20, AA) was repeatedly backcrossed with B. campestris to place B. campestris nucleus in the cytoplasm of B. oxyrrhina. Alloplasmic plants, obtained in BC5 generation, were stably male sterile but mildly chlorotic during initial development. Synthetic alloploid B. oxyrrhina-campestris was also hybridized with B. juncea to transfer B. oxyrrhina cytoplasm. Segregation for green and chlorotic plants was observed in BC1 and BC2 generations. By selection, however, normal green male sterile B. juncea was obtained in BC3. Pollen abortion in both B. campestris and B. juncea is post-meiotic.
