    Analysis of the standard deletion algorithms in exact fit domain binary search trees (1990)
    Springer
    Algorithmica 5 (1990), S. 295-311 
    Details
    ISSN: 1432-0541
    Keywords: Binary search tree ; Data structure ; Average case analysis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Computer Science , Mathematics
    Notes: Abstract It is well known that the expected search time in anN node binary search tree generated by a random sequence of insertions isO(logN). Little has been published about the asymptotic cost when insertions and deletions are made following the usual algorithms with no attempt to retain balance. We show that after a sufficient number of updates, each consisting of choosing an element at random, removing it, and reinserting the same value, that the average search cost is Θ(N 1/2).

    Fast stable in-place sorting withO(n) data moves (1996)
    Springer
    Algorithmica 16 (1996), S. 151-160 
    Details
    ISSN: 1432-0541
    Keywords: Sorting ; Stability ; Data moves ; In-place
    Source: Springer Online Journal Archives 1860-2000
    Topics: Computer Science , Mathematics
    Notes: Abstract Until recently, it was not known whether it was possible to sortstably (i.e., keeping equal elements in their initial order) an array ofn elements using onlyO(n) data moves andO(1) extra space. In [13] an algorithm was given to perform this task inO(n 2) comparisons in the worst case. Here, we develop a new algorithm for the problem that performs onlyO(n 1+ε) comparisons (0〈ε〈1 is any fixed constant) in the worst case. This bound on the number of comparisons matches (asymptotically) the best known bound for the same problem with the stability constraint dropped.

    Infestation of Stored Products by Insects (1933)

    Notes: [Auszug] ALTHOUGH the losses caused to growing crops by insects have long been recognised, the losses caused to crops after harvesting and during storage and transport have been strangely neglected both by the biologist and the industrialist. These losses are none the less of grave importance and take in ...

    Use of Hydrogen Cyanide in Fumigation (1935)

    Notes: [Auszug] THE recent tragic death of two children from hydrogen cyanide fumes following the fumigation of their home in Aldershot has directed attention to the need for stricter control of the practice of fumigation and to the need for fuller knowledge of it. For some years past I have strongly urged the ...

    The spawning seasons of Caribbean reef fishes (1973)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 5 (1973), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Observations are recorded on the time of spawning of 83 species of Caribbean reef fishes. Details of seasonal variations in the percentage of sexually active fishes are given for 35 species. The majority of species spawn mostly when water temperatures are minimal, in February, March and April. The expected biomass of reef fish eggs in the plankton is about twelve times greater in the above mentioned period than in the period from June to December. Normal recruitment to insular fisheries may be very greatly dependent upon the success of parent stocks spawning elsewhere in the Caribbean and the abundance of recruits to a particular area may be dependent upon the speed and direction of the prevailing currents which carry larvae and juveniles to the insular shelves.

    Aspects of the biology and ecology of Caribbean reef fishes: Serranidae (hinds and groupers) (1978)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 12 (1978), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Hinds and groupers (Teleostei, Serranidae) form a valuable component of catches of reef fishes in the Caribbean Sea and adjacent regions. Investigations of species in Jamaican waters have covered relative and absolute growth rates, spawning seasons, fecundity, size at maturity and at sex change, and size compositions, mortality rates, and relative abundances of exploited and unexploited populations.

    POTENTIAL PASTURE PRODUCTION IN THE UPLANDS OF WALES (1974)

    Grass and forage science 29 (1974), S. 0 
    Details
    ISSN: 1365-2494
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: The DM and N contribution of S184 white clover in mixed ryegrass/clover swards was recorded at Pant-y-dwr Hill Centre (305 m) for 4 years, 1967–70. By direct comparison with fertilized grass swards it was estimated that the clover N contribution on peaty gley soil averaged 100 kg N/ha per year (89 Ib N/ac) under cutting and 98 kg N/ha (87 ib/ac) under grazing with faecal return. On more fertile acid brown earth the corresponding contributions were 81 and 90 kg N/ha (72 and 80 Ib/ac). Full replacement of clover by N fertilizer would require average annual applications of 268, 229, 156 and 128 kg fertilizer N/ha, respectively (239, 204, 139 and 114 Ib N/ac).
