  1. Blue whales <em>Balaenoptera musculus</em> in offshore waters of Kenya

    Blue whales <em>Balaenoptera musculus</em> in offshore waters of Kenya

    Item type: Journal Article • Journal: African Journal of Marine Science
    Observations of blue whales were made in Kenyan offshore waters during a seismic survey from September 2014 to January 2015. These represent the first live at-sea sightings of blue whales reported from Kenyan waters. All 30 sightings occurred between September...
  2. The autumn occurrence and spatial distribution of cetaceans in the waters of Mauritania during a geophysical survey in 2012

    The autumn occurrence and spatial distribution of cetaceans in the waters of Mauritania during a geophysical survey in 2012

    Item type: Journal Article • Journal: African Journal of Marine Science
    This study aimed to identify the occurrence and spatial distribution of cetaceans in Mauritanian waters (eastern Atlantic). A geophysical survey was conducted over 92 days between September and December 2012. Over 967 km was surveyed, with 1 017 h of...
  3. BOOK REVIEWS

    Item type: Journal Article • Journal: South African Forestry Journal
  4. Genetic Variation in Some Growth and Wood Properties among 18 Full-sib Families of South African <em>Grown Eucalyptus grandis:</em> A Preliminary Investigation

    Item type: Journal Article • Journal: South African Forestry Journal
    Estimates of the genetic parameters for a number of tree and wood properties were obtained using 18 controlled pollinated families selected for rapid growth from a 9-year-old progeny trial consisting of 71 controlled pollinated families and one commercial control. Significant...
  5. Wood Property Variation in Six <em>Pinus radiata</em> (D. Don) Trees Grown in the Jonkershoek State Forest

    Item type: Journal Article • Journal: South African Forestry Journal
    The sources of variation, their relative contribution to the total and random variation, and the general pattern of variation were investigated for total ring width, latewood width, latewood percentage, grain angle, basic density and fibre length.
  6. Direct Gamma Ray Densitometry of Wood

    Item type: Journal Article • Journal: South African Forestry Journal
    Wood density was determined in various wood species representing a wide range of densities using 60 KeV collimated soft gamma radiation from an Americium241 energy source. In the samples examined wood mass attenuation coefficients varied from 0,170 to 0,210 cm2g...
  7. Physical and Morphological Changes of Wood Fibres During Beating and Recycling

    Item type: Journal Article • Journal: South African Forestry Journal
    To present a clear picture of exactly how the surfaces of recycled fibres were changed during successive beating cycles, scanning electron microscope (SEM) micrographs were taken of unbeaten pulp and afterwards of the same pulp subjected to one, four and...
  8. Pulping Characteristics of <em>Eucalyptus</em> Provenance Trials Grown in the Western Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    For the purpose of Part I of this investigation, eight eucalypt species (irrespective of provenance), 12 years of age and grown along the northern slope of Stellenbosch mountain in the Western Cape were chipped, screened and pulped using the Kraft...
  9. Preparation of Moulding Resins from Inexpensive By-products: Substitution of Phenol Novolac with Unmodified Lignin in Moulding Resin and its Effect on Physical Properties of Mouldings

    Item type: Journal Article • Journal: South African Forestry Journal
    Mouldings of 25% resin content were prepared. Substitution of phenol novolac with various ratios of unmodified bagasse lignin was investigated. The effect of lignin incorporation on tensile and dimensional stability properties of mouldings was then studied. Low levels of lignin...
  10. Basic Density, Tracheid Length and Strength Properties of Juvenile and Mature Wood of <em>Pinus patula</em> Grown in Tanzania

    Item type: Journal Article • Journal: South African Forestry Journal
    More than 70% of Tanzanian plantations consist of conifers, 60% of which are Pinus patula plantations. Juvenile wood is one of the most important sources of variability.
