Properties of natural organisms and its use in technological architecture

This research aimed at identifying natural organisms and their properties in the technological samples of contemporary architecture. The main questionswere: "Which properties of natural organisms are effective on the technological works of contemporary architecture?" and "How much do they affect?"This descriptive-analytic research was conducted using archival method to access the theoretical...

Maize response to water, salinity and nitrogen levels: yield-water relation, water-use efficiency and water uptake reduction function

Water, salinity and nitrogen are the major factors affecting maize production in arid and semi-arid areas. The objectives of this study were to investigate the effects of different water, salinity and nitrogen levels on yield-water relationships, water use, water productivity (WP), water use efficiency (WUE) and water uptake reduction function by maize hybrid SC-704 in a semi-arid area and ...

Soil water regime and water concervation efficiency in a non-irrigated semi-arid environment

Population , Natural Resources and Environment

Population-environment studies have implicitly permeated demography but only until the mid-20 century has the debate been rekindled and research expanded. This article reviews the origins and history of the population-environment debate and attempts to provide insight into the most recent approaches and methodology. Beginning with the most traditional relationships established between demograph...
