Rainwater harvesting from rooftop catchments



The application of an appropriate rainwater harvesting technology can make possible the utilization of rainwater as a valuable and, in many cases, necessary water resource. Rainwater harvesting has been practiced for more than 4, 000 years, and, in most developing countries, is becoming essential owing to the temporal and spatial variability of rainfall. Rainwater harvesting is necessary in areas having significant rainf ....etc

Definition
It is any technology, which exploits phenomena, and structures that can only occur at the nanometer scale, which is the scale of several atoms and small molecules. Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications.




Overview
The related term nanoscience is used to describe the interdisciplinary fields of science devoted to the study of nanoscale phenomena employed in nanotechnology. This is the world of atoms, molecules, m ....etc

Rethinking Connectivity in Developing Nations

ABSTRACT
This paper outlines a migration path towards universal broadband connectivity, motivated by the design of a wireless store-and-forward communications network.
We argue that the cost of real-time, circuit-switched communications is sufficiently high that it may not be the appropriate starting point for rural connectivity. Based on market data for information and communication technology (ICT) services in rural India, we propose a combination of wireles ....etc

Bamboo, a species of plant in the grass family possessing good strength and flexibility can be used as a building material. However, due to the emergence of better building materials, bamboos use is limited to certain applications only. Besides the extensive use of steel and other building materials for the construction in the present trend, bamboo can replace wood and steel in many applications like roof covering, footbridges, reinforcement, scaffolding, bamboo houses, etc which accounts for low cost construction. ....etc
