Understand the energy demand behaviours for a sustainable management of the natural resources in Cameroon. [PDF]
In order to fall under a prospect for sustainable management of the natural resources in Cameroon, this communication tries, using a 1996 survey carried out from 400 households in the towns of Yaounde, Mbalmayo and Ebolowa, to understand the demand ...

Effect of nitrogenous bases on the thermal stability of jet fuels [PDF]
Fuels from naphthenic petroleums were evaluated, and it was found that they had more N bases than those paraffinic ones (0.00024 and 0.000009% N, respectively).

Investigation of storage system designs and techniques for optimizing energy conservation in integrated utility systems. Volume 1: (Executive summary) [PDF]
Integrated Utility Systems (IUS) have been suggested as a means of reducing the cost and conserving the nonrenewable energy resources required to supply utility services (energy, water, and waste disposal) to developments of limited size.

An evaluation of the economic benefits of active cooling and carbon dioxide enrichment of greenhouse cucumbers (Cucumis sativus L.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Horticultural Science at Massey University [PDF]
, 1996 Cooling a greenhouse with a refrigeration system rather than conventional ventilation makes it possible to maximise the fractional enrichment time for carbon dioxide, and more importantly enrich during periods of high photosynthetically active radiation.

Characterization of paraffin-based fuels and paraffin waxes for hybrid rocket engines
, 2015 This thesis develops an investigation on the rheological and mechanical properties of a class of paraffin-based fuels for hybrid rocket engines. They are obtained by mixing a paraffin wax and a polymer (SEBS, EVA and PE). Mixtures have a content of polymer equal to a 2,5%, 5%, 7,5% and 10%.
