Palm kernel shell as fuel for burning bricks

The use of an agricultural waste product, palm kernel shell, as a fuel for firing bricks is explored as a means of reducing environmental degradation and depletion of scarce firewood in Ghana. A simple but efficient methodology of clamp firing bricks using the new fuel is developed and tested. The resulting bricks are analysed for physical properties and suitability for construction use. The viability of palm kernel shell as a fuel for small-scale brick industries is considered. On etudie actuellement au Ghana les possibilites d'utilisation d'un dechet agricole, en l'occurrence, les coquilles de noix de palme, comme combustible dans les briqueteries; une telle solution permettrait de reduire la degradation de l'environnement et de diminuer l'appauvrissement des maigres reserves en bois de chauffage du pays. A cet effet, on met au point une methodologie simple mais efficace de cuisson des briques en brulant des dechets de coquilles de noix de palme. On analyse les proprietes physiques de ces briques et on verifie qu'elles conviennent a la construction. On etudie la viabilite de la coquille de noix de palme pour l'alimentation en combustible des petites briqueteries.

我国矿产资源开发与区域经济发展的关系研究

矿产资源丰裕度、矿产资源开发强度和矿产资源依赖度是研究矿产资源开发利用与区域经济发展分析的重要参数。本文利用2013年度全国非油气矿产资源开发利用统计数据研究这3个参数发现,全国煤炭基础储量东、中、西部占比为7.2%、49.4%和43.4%,矿产资源开发利用强度为20.51%、42.12%和37.38%,矿产资源依赖度为分别为0.99%、5.88%和5.94%。可以看出,西部地区矿产资源相对最为丰富,且矿产资源开发强度也远领先于东、中部地区,但其经济增长速度却相对缓慢。这主要是由于西部地区矿产资源产业布局不合理、人力资源与技术创新不足、资源开发利用监管制度不健全、地理条件险恶和基础设施落后等原因造成的。因此,建议西部地区开发利用矿产资源要优化产业结构、提高资源开发利用效率、加大技术创新投入、拓展矿业资源产业链、优化企业发展环境、保障企业稳定发展基础来实现资源开发、经济增长及环境保护的协调发展。     

Is the association between temperature and mortality modified by age, gender and socio-economic status?

Background

A number of studies have examined the relationship between high ambient temperature and mortality. Recently, concern has arisen about whether this relationship is modified by socio-demographic factors. However, data for this type of study is relatively scarce in subtropical/tropical regions where people are well accustomed to warm temperatures.

Objective

To investigate whether the relationship between daily mean temperature and daily all-cause mortality is modified by age, gender and socio-economic status (SES) in Brisbane, Australia.

Methods

We obtained daily mean temperature and all-cause mortality data for Brisbane, Australia during 1996-2004. A generalised additive model was fitted to assess the percentage increase in all deaths with every one degree increment above the threshold temperature. Different age, gender and SES groups were included in the model as categorical variables and their modification effects were estimated separately.

Results

A total of 53,316 non-external deaths were included during the study period. There was a clear increasing trend in the harmful effect of high temperature on mortality with age. The effect estimate among women was more than 20 times that among men. We did not find an SES effect on the percent increase associated with temperature.

Conclusions

The effects of high temperature on all deaths were modified by age and gender but not by SES in Brisbane, Australia.

重塑矿产资源勘查开发格局的初步思考

重塑矿产资源勘查开发格局是我国勘查开发领域至关重要的问题,也是《找矿突破战略行动纲要（2011—2020年）》核心目标之一。本文以《找矿突破战略行动纲要（2011—2020年）》为研究基础,总结提出了矿产资源勘查开发格局的内涵。在此基础上,构建了我国矿产资源勘查开发格局的评价指标体系,并明确应用思路。最后,针对勘查开发现状及存在的问题,以指标体系为导向,提出重塑矿产资源勘查开发格局机制体制创新方面的建议。     

PREVI-Lima’s Time: Positioning Proyecto Experimental de Vivienda in Peru’s Modern Project

Launched in 1968, the PREVI-Lima housing competition brought informal urbanisation to the attention of architects worldwide. The competition brief required the design of low-rise, high-density expandable homes, grouped in neighbourhoods. Here Sharif S Kahatt puts PREVI’s experimental project within the social, political and theoretical context of the time. Copyright © 2011 John Wiley & Sons, Ltd.
