  2. Stress Grading of <em>Eucalyptus grandis</em> for Use in Laminated Beams

    Item type: Journal Article • Journal: South African Forestry Journal
    Mechanical as well as visual tensile stress grading of Southern African Eucalyptus grandis is discussed. Results of a large number of tests are presented. Correlations between bending stiffness and tensile strength, between density and tensile strength, amongst others, are shown...
  3. Response of <em>Eucalyptus</em> to Aldicarb in Coastal Sandy Soils in Natal, South Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    The planting of Eucalyptus on aeolian; recent sands of the Natal coast has raised the question of whether nematicides are as necessary to counter patchy, unthrifty growth, as they are for sugarcane. The heights of eucalypts were mea sured at...
  4. Derivation of Grade Stresses for South African Pine Plywood

    Item type: Journal Article • Journal: South African Forestry Journal
    Very little use has been made of plywood in engineered timber structures in South Africa. One of the reasons could be that little or no information was available regarding the mechanical properties of the currently produced S.A. pine plywood. This...
  5. S A Pine—Load Sharing. Fact or Fiction?

    Item type: Journal Article • Journal: South African Forestry Journal
    Load sharing amongst timber members, that are restrained to the same deflection, has been accepted as a given fact for some time. This paper discusses a simulation method that can be used to determine whether load sharing does in fact...
  6. Grond‐ en afloopverlies bepalings vanaf natuurlike veld, met behulp van ‘n reënvalnabootser

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    ‘n Oorhoofse roterende reënvalnabootser is gebruik om die sediment‐ en afloopverliese vanaf natuurlike veld in verskillende suksessiestadia en teen verskillende hellings te bepaal.
  7. Toepassíng van ‘n gronderosievergelyking op natuurlike veld van die sentrale oranje‐vrystaat

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    ‘n Oorhoofse roterende rcënvalnabootscr is gebruik orn numericse waardes vir sekere faktore van die universele gronderosi‐evcrgelyking vas te stel. Alhocwei dit tydens hierdie Studie nodig was om sekere belangrike aannames te maak, het die afgeleide data betekenisvol ooreengestem met die...
