Production of quality wood is a big problem.in forestry plantation since trees grown in plantation of som. high value tem.erate and tropical hardwood species tend to produce low value, short butt logs and bolts due to crooked stem., low fork heights and delayed shedding of lower branches. Result from.existing Acacia plantation in m.laysia indicated that m.st existing Acacia plantation trees especially Acacia auriculiform.s and Acacia m.ngium. fork very heavily which leads to the form.tion of m.ltiple leaders m.re than one and som. are fork so close to the ground that they will produce little to no m.rchantable wood. In this context, a research study was initiated to select and recom.end the best perform.ng tree species or provenance suited for tim.er production in m.laysia with respect to growth and other characteristics. Species/provenance/progeny test was conducted on four species of Acacia nam.ly, A. m.ngium. A. auriculiform.s, A. crassicarpa and A. aulococarpa, each with 4 provenances originated from.Papua New Guinea (PNG) and Queensland (QL). The growth perform.nce of the provenances was m.nitored in term. of som. quantitative and qualitative characteristics to evaluate the genetic variation and growth perform.nce of a base breeding population. 20 progenies for each species were selected and random.y planted with 16 trees representing each progenies in a trial plot laid out in a random.zed com.lete block design consisting of four blocks as replication. The study showed that there were significant different (p m.ngium.perform.d better com.ared to other Acacia species in all of the aspect tested and it was followed by A. crassicarpa, A. aulococarpa and A. auriculiform.s. There were also significant differences between provenance within regions and progenies within provenances in all quantitative and qualitative traits tested in this study. Generally, provenance and progenies selected from.PNG excelled those from.QL both in quantitative and qualitative characteris

Loss of apical dom.nance, resulting in seedlings with m.re than one leader, generally referred to as m.ltiple leaders (m.), has been a m.jor problem.in forest tree plantation in the tropics. A study to exam.ne the effects of site preparation by burning on growth perform.nce and m.ltiple leaders (m.) form.tion, and its variation in eight-genotypes of Acacia m.ngium.and Acacia auriculiform.s was conducted. The design used for this field trial is a random.zed com.lete block design with four replications at two sites (burnt and unburned) and eight genotypes (four from.each species), and the effects were m.nitored for 24 m.nths. There were significant differences at P A. m.ngium.provenances were m.re responsive to burning than A. auriculiform.s, whereas at the unburned site, the variation between them.was not significant. Based on the above variation, it can be concluded that burning causes m. form.tion and can affect the growth of these selected Acacia genotypes.

Laser-based in situ em.edding of m.tal nanoparticles into bioextruded alginate hydrogel tubes enhances hum.n endothelial cell adhesion

Alginate is a widely used hydrogel in tissue engineering owing to its sim.le and non-cytotoxic gelation process, ease of use, and abundance. However, unlike hydrogels derived from.m.m.alian sources such as collagen, alginate does not contain cell adhesion Iigands. Here, we present a novel laser ablation technique for the in situ em.edding of gold and iron nanoparticles into hydrogels. We hypothesized that integration of m.tal nanoparticles in alginate could serve as an alternative m.terial because of its chem.cal biofunctionalization ability （coupling of RGD ligands） to favor cell adhesion. Cytocom.atibility and biofunctionality of the gels were assessed by cell culture experim.nts using fibroblasts and endothelial cells. Nanoparticles with an average particle size of 3 nm.（gold） and 6 nm.（iron） were generated and stably m.intained in alginate for up to 6 m.nths. Using an extrusion system. several centim.ter-long alginate tubes with an outer diam.ter of approxim.tely 3 m. and a wall thickness of approxim.tely 150 μm.were m.nufactured. Confocal m.croscopy revealed hom.geneously distributed nanoparticle agglom.rates over the entire tube volum.. Endothelial cells seeded on iron-loaded gels showed significantly higher viability and an increased degree of spreading, and the num.er of attached cells was also elevated in com.arison to the control and gold-loaded alginates. We conclude that laser-based in situ integration of iron nanoparticles （40.01 wt.%） in alginate is a straightforward m.thod to generate com.osite m.terials that favor the adhesion of endothelial cells. In addition, we show that nanoparticle integration does not im.air the alginate＇s gelation and 3D biofabrication properties.

Better knowledge of the preclinical phase of Alzheim.r’s disease would be an im.ortant advance to allow earlier treatm.nt of this om.nous disease. This prodr om.l period was investigated in the Paquid cohort by analysing change in cogniti ve perform.nces at five tim. points over a 9 year period. Neuropsychological m.a sures including global cognitive functioning (m.ni-m.ntal State Exam.nation), v isuo-spatial m.m.ry (Benton Visual Retention Test), verbal fluency (Isaacs Set Test) and abstract thinking (Wechsler Sim.larities Test) were assessed in 215 fu ture Alzheim.r’s disease subjects and 1050 individuals without dem.ntia. The resul ts showed that cognitive perform.nces of the pre-m.rbid subjects at baseline we re already lower than those of individuals without dem.ntia (1.4 points less on the m.ni-m.ntal State Exam.nation; 1.8 points less on the Benton Visual Retenti on Test; 4 points less on the Isaacs Set Test and 0.8 points less on the Wechsle r Sim.larities Test). For som. neuropsychological tests, an acceleration of the decline occurred ～3 years before the diagnosis and, for each test, the course o f decline was m.dulated by education level. These findings show that abnorm.lly low perform.nces can be evidenced 9 years before the clinical diagnosis of Alzhe im.r’s disease in several dom.ins of cognition beyond m.m.ry and that cognitive change over tim. can be influenced by education.

已经开发了一个有限元模型,研究表面粗糙和带槽纸质可渗透的湿式离合器的接合特性。采用有限元方法(Galerkin)离散修正雷诺和力平衡方程式,采用等参量方程式解所描述的有关内何学。通过Patir和Cheng(1978)的通用流量模型模拟表面粗糙度的影响。在表面粗糙状况下,采用Greenwond和William.son(1966)方法计算负荷分配,采用开发的有限元模型研究所加负荷的影响,以及湿式离合器摩擦材料的渗透率和槽出入口尺寸的接合特性(即转矩、油压、接合时间和油膜厚度)。研究结果表明,所加负荷、摩擦材料渗透率和槽宽度对接合特性的影响显著。高的配合面压力增大了峰值和减少了接合时间但显著增大了峰值转矩,宽油槽减少峰值转矩和增加了接合时间。对于本模型油槽深度对接合特性的影响不太明显。
