Conventional breeding requires long breeding cycles which limits selection intensity due to large tree sizes and high costs associated with assessing properties. In contrast very early selection offers a short cycle and assesses corewood which is the poorest wood in the tree. Young Pinus radiata trees were deliberately leant to produce separately opposite wood (OW) and compression wood (CW). Th...

The sintering behaviour of several green compacts made with olivine or olivine/alumina powder blends has been examined. To this goal, powders were attrition milled, uniaxially pressed into specimens and air sintered at temperatures ranging from 1100 to 1300 °C. The resulting samples were characterized by water absorption, shrinkage, phase composition and density. Compositions containing 5%, 10%...

Polymerization shrinkage is a critical factor affecting the longevity and acceptability of dental composite resins. The aim of this work was to evaluate the effect of light intensity and irradiation time on the polymerization process of a photo cured dental composite resin by measuring the Vickers hardness number (VHN) and the volumetric polymerization shrinkage. Samples were prepared using a d...

We give James-Stein type estimators of multivariate normal mean vector by shrinkage to closed convex set K with smooth or piecewise smooth boundary. The rate of shrinkage is determined by the curvature of boundary of K at the projection point onto K . By considering a sequence of polytopes K j converging to K , we show that a particular estimator we propose is the limit of a sequence of estimat...

In the present study, impact of shrinkage on pyrolysis of biomass particles is studied employing a kinetic model coupled with heat transfer model using a practically significant kinetic scheme consisting of physically measurable parameters. The numerical model is used to examine the impact of shrinkage on temperature profile and pyrolysis conversion time considering cylindrical geometry. Finite...

Highly plastic expansive clays swell or shrink due to change in moisture content and they often have very low bearing capacity. Construction of engineering structures particularly pavements lightweight buildings on problematic soils such as highly may create severe structural problems poor properties that kind soil. This study focused the influence fly ash strength which are their undesirable c...

The objective of this work was to formulate a mathematical model for predicting a safe weight of lift. Considering the intratruncal pressure, post-work height shrinkage of the worker and strain energy of the intervertebral disc, the SWL function was derived in terms of the Young Modulus of elasticity (E) of the articular cartilage (endplate of the disc); velocity of lift (u); acceleration due t...

Rheoplastic lightweight concrete (RLC) is generally designed for pumping applications as fluid free from segregation. Concrete produced using polymeric admixtures to enhance workability, strength, drying shrinkage, and durability. This research investigated the suitability of natural porous pumice aggregates in Turkey obtain rheoplastic with cement content normal ranges. To produce experience m...
