Appraisal and ranking of poly-aluminium chloride, ferric chloride and alum for the treatment of dairy soiled water
Mohamed, A.Y.A.; Siggins, Alma; Healy, Mark G.; Ó hUallacháin, Daire; Fenton, Owen; Tuohy, Patrick (Elsevier, 2020-04-29)Land spreading of dairy soiled water (DSW) may result in pollution of ground and surface waters. Treatment of DSW through sludge-supernatant separation using chemical coagulants is a potential option to reduce the negative ... -
The effect of thinning on mechanical properties of Douglas fir, Norway spruce, and Sitka spruce
Krajnc, Luka; Farrelly, Niall; Harte, Annette M. (Springer Verlag, 2019-01-07)Context: The relationship between silvicultural management and the quality of timber produced is not entirely elucidated. Aims: The effects of thinning on structural grade-determining properties of wood (elastic modulus, ... -
The influence of crown and stem characteristics on timber quality in softwoods
Krajnc, Luka; Farrelly, Niall; Harte, Annette M. (Elsevier, 2018-12-28)The relationships between several crown and tree properties and timber quality were examined on three softwood species: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), Norway spruce (Picea abies (L.) H. Karst) and Sitka ... -
Mechanical characterisation of green Sitka spruce logs
Krajnc, Luka; Farrelly, Niall; Harte, Annette M. (NUI Galway, 2016-08-29)ABSTRACT: Timber is by its nature a very heterogeneous material. Many different factors impact its mechanical properties, from tree species to environment (climate, competition, soil…). While a number of studies in the ... -
Relationships between wood properties of small clear specimens and structural-sized boards in three softwood species
Krajnc, Luka; Farrelly, Niall; Harte, Annette M. (De Gruyter, 2019-06-12)Research on the mechanical and physical properties of wood is commonly carried out on either small clear specimens or structural-sized boards. The first approach was more frequently utilised in the past, while the latter ...
