建筑火灾风险评估研究

目前,建筑火灾风险评估常用方法有基于模糊数学的模糊综合评判法和基于性能化设计的性能化评估方法.在前人研究的基础上,利用系统原理,把建筑作为一个由若干相对独立的空间区域组成的系统,通过评估各个区域的火灾风险来确定整个建筑的火灾风险.该方法的优点是便于防火设计和管理人员确定重点防火区域,通过降低重点区域的火灾风险,来降低整个建筑的火灾风险.

Enhancing climate technology transfer through greater public–private cooperation: Lessons from Thailand and the Philippines

This article contributes to debates about climate change policy and technology transfer by analyzing the success factors underlying collaboration between private companies and communities in developing countries. To date, much attention to capacity building for enabling environments — including public–private collaboration — under the climate change convention has focused on state‐led initiatives and on the innovation and development of technologies. This article, instead, focuses on how private‐sector investors and host communities may collaborate in the diffusion of technologies, by reducing the costs of technology transfer, and making technology more appropriate to developing countries. The article describes cases of collaboration concerning waste management and waste‐to‐energy in Thailand and the Philippines. The article argues that successful public–private partnerships between investors and communities depends on minimizing transaction costs, strengthening collaborative (or assurance) mechanisms, and in maximizing public trust and accountability of partnerships. Lessons are then drawn for enhancing capacity building for technology transfer under the climate change convention and applications such as the Clean Development Mechanism.

An Overview on the Mechanical Behaviour of Biodegradable Agricultural Films

The mechanical behavior of various types of biodegradable materials depends, mainly, on their chemical composition and the application conditions. Various additives are added into the bioblends to improve their properties, which sometimes even reach the levels of the conventional plastics. It is well known that the environmental conditions during production, storage, and usage of these materials influence their mechanical properties. Ageing during the useful lifetime also causes great losses in the elongation. In the present paper, the overall mechanical behavior of biodegradable films, which may be considered suitable for agricultural applications, but also of partially biodegradable films, is reviewed and analyzed. Selected critical mechanical properties of films before their exposure to biodegradation are investigated and compared against those of conventional agricultural films.
