Modelling of vertical density profile of particleboard,manufactured from hardwood sawmill residue

Abstract

Particleboards are generally made in three layers using softwood as the major raw material. Limitation on natural wood resources and concerns about the carbon footprint of products has created a significant interest in environmentally friendly or ‘green’ building materials. Hardwood sawmill residue, which has been disposed as solid waste, was investigated by authors as the main raw material for producing particleboard at RMIT University, Australia. Physical and mechanical properties of final particleboard were measured and analysed against original materials and process variables. The density of a particleboard along its thickness direction is not uniform, and is called the vertical density profile (VDP) which is dependent upon processing parameters. The VDP influences particleboard properties including flexural strength and its dimensional stability and fastening capacity. It is important to influence the formation of the VDP, altering processing variables, to achieve optimum particleboard properties. This paper presents an attempt to develop a model to predict the formation of the VDP of hardwood residue particleboard compared to processing parameters, using the theory of experimental design. The advantages of such a model in optimising particleboard properties are also discussed.

高速公路互通区的印象塑造与情感表达

在当前快速城市化进程的条件下，生态环境日益恶化，针对我国高速公路互通区绿地建设实况，认为高速公路互通区具有焦点空间、生态优先、可识别性强、潜在价值高的特征，但在充分利用它的特有功能方面认识不足，开发力度不够。通过总结归纳高速公路互通区印象塑造与情感表达的景观设计要点，以京福高速枣庄互通区景观设计为例，让外来游客了解当地并留下深刻印象，同时也给本地居民以归属感和认同感。

“场所精神”在洱源西湖国家湿地公园南片区设计理念中的应用

场所精神是规划设计的灵魂。在洱源西湖国家湿地公园规划项目中，从分析“烟渚渔村”场地肌理入手，提出“幸福就在拐弯处”这一体现人本主义价值观的设计理念，并依据“渚岛”式大园林景观规划结构，构建了“一轴（生态旅游带）、七区（7个功能片区）的空间结构形态，建立了“岛与岛一水与岛一水与水一水与建筑”之间的相互交错的拓朴关系形态，探讨了各“渚岛”不同的情景规划设计的可能性。

Monitoring distances travelled by horses using GPS tracking collars

Objective The aims of this work were to (1) develop a low-cost equine movement tracking collar based on readily available components, (2) conduct preliminary studies assessing the effects of both paddock size and internal fence design on the movements of domestic horses, with and without foals at foot, and (3) describe distances moved by mares and their foals. Additional monitoring of free-ranging feral horses was conducted to allow preliminary comparisons with the movement of confined domestic horses. Procedures A lightweight global positioning system (GPS) data logger modified from a personal/vehicle tracker and mounted on a collar was used to monitor the movement of domestic horses in a range of paddock sizes and internal fence designs for 6.5-day periods. Results In the paddocks used (0.8–16 ha), groups of domestic horses exhibited a logarithmic response in mean daily distance travelled as a function of increasing paddock size, tending asymptotically towards approximately 7.5 km/day. The distance moved by newborn foals was similar to their dams, with total distance travelled also dependent on paddock size. Without altering available paddock area, paddock design, with the exception of a spiral design, did not significantly affect mean daily distance travelled. Feral horses (17.9 km/day) travelled substantially greater mean daily distances than domestic horses (7.2 km/day in 16-ha paddock), even when allowing for larger paddock size. Conclusions Horses kept in stables or small yards and paddocks are quite sedentary in comparison with their feral relatives. For a given paddock area, most designs did not significantly affect mean daily distance travelled.
