城乡规划行政与行业发展

美国规划协会的会员构成广泛,能充分发挥主体作用影响规划行政,能为规划机构提供专业性服务.借鉴美国规划协会的经验,我国城市规划行业发展应采用以规划行政为主导,政府与非政府组织优势互补、合作共赢,发展行业自律的思路.     

设计意象的建筑表达——国家空管委疗养基地创作分析

国粮院粮食加工领域近30年发展与展望

时值《粮油食品科技》创刊30周年之际，记录总结国家粮食和物资储备局科学研究院（以下简称“国粮院”）近30年在粮食加工领域的发展情况，并进行了展望，以期为国粮院下一步升级发展提供参考。全文共分四部分：一是总结回顾自上世纪90年代以来我国粮食加工领域的发展情况。二是概述了近30年来国粮院在粮食加工领域的重要成果及其对推动该领域发展的贡献，从政策建议、科技创新及标准引领等方面，推动了二十世纪九十年代我国粮食加工链条从初级加工向粮食食品加工的延伸，“十五”、“十一五”期间为提升我国粮食食品供给保障能力提供了支撑，通过从杂粮到全谷物的健康谷物食品研究布局，从“十一五”至今，专注于营养健康谷物食品加工领域，有力推动了我国粮食加工行业转型升级。三是在保障国家粮食安全与人民生命健康大背景下，分析了新时代我国粮食加工领域发展面临的挑战与机遇。四是结合我国重要战略布局，进一步展望国粮院在粮食加工领域未来发展中的重点工作与使命，作为我国唯一的国家级粮食行业公益性科研机构，国粮院将进一步加强我国全谷物领域的科技创新、标准体系建设、科普引领及全民推广等方面的工作，助力健康中国建设和加工环节的节粮减损，推动我国粮食产业高质量发展。     

Prediction of non-woven geotextiles’ reduction factors for damage caused by the drop of backfill materials

The need for sustainable solutions in geotechnical works has encouraged the investigation of recycled construction and demolition wastes (RCDW) as backfill material. The possible damages caused by the launching (dropping) process of this “new” backfill material (RCWD) must be quantified for its combined use with geosynthetics. This study evaluated the influence of the backfill's grain-size distribution and the geotextile's mass per unit area in the damages caused by the launch of RCDW material and aimed to provide a prediction equation of the reduction factors. Five RCDW materials were launched from 1.0-m and 2.0-m height over five non-woven polyester needle-punched geotextile and specimens were exhumed to be tested under tensile. Databases were created with the results and subjected to machine learning to obtain a prediction equation for the reduction factor's values. The results show that the damages caused by the dropping height are complex. The 1.0-m increase in the drop height and the increase in the geotextile's mass per unit area cannot be associated with an increase in the damage. The geotextiles were more affected by the backfills with uniform gradation. A reduction factor's prediction equation is presented considering the three variables investigated (geotextile, drop height and backfill material classification). The artificial neural network is a more interesting solution than multiple linear regression since it does not possess several application criteria and provides more accurate predictions.     

Digital Workflows and the Expanded Territory of the Architect

Particularly in areas of Africa and Asia, efforts are being made to accommodate new economic development without obliterating the rural way of life. Termed ‘New Ruralism’, the approach involves architects cooperating closely with local communities, ensuring that projects respect their cultural heritage and empowering them to actively participate in shaping their environment. The process is as important as the form in driving sustainability. Guest-Editor Richard Garber explains the principles and illustrates them with a project in China by his own firm GRO Architects, and one in Kenya by his former employers SHoP Architects.
