In Kampala, Uganda, about 28,000 tonnes of waste are collected and delivered to landfill every month. Kampala Capital City Authority records show that this represents approximately 40 % of the waste generated in the city. The remaining uncollected waste is normally burnt and/or dumped in unauthorised sites, causing health and environmental problems. However, the organic fraction of domestic was...

AIM To compare the burning characteristics of the tobacco and paper of manufactured and hand rolled cigarettes, and set a fire safety standard of manufacture to largely reduce the fire risk from discarded cigarettes. METHODS (1) Cigarette extinction test of ignition strength: 40 cigarettes per brand, lit and placed on 15 layers of filter paper, in accordance with ASTM test standard E2187-02. ...

A pot experiment was used to assess the N uptake by pine seedlings 24 during two years on a burnt soil added with 15 N-labelled ryegrass, obtained from 25 a 15 N-enriched sample of this soil after the fire. Nitrogen concentration in needles, 26 stems and roots of seedlings decreased significantly from the first to the second 27 1.12% of the added ryegrass-15 N was recovered: two thirds in the s...

Horizontal black surfaces are usually very attractive to polarotactic aquatic insects, since they generally reXect highly and horizontally polarized light, and thus imitate water surfaces. We monitored highly polarizing black burnt-up stubble-Welds, but surprisingly never found aquatic insects or their carcasses in the ash, although Xying polarotactic insects were abundant in the area, which we...

The rheology of lime binders, which is critical in the final performance of lime mortars and plasters, is poorly understood, particularly in its relationship with the microstructure and colloidal characteristics of slaked lime (Ca(OH)(2)) suspensions (i.e., lime putties). Here, the contrasting flow behavior of lime putties obtained upon slaking (hydration) of soft and hard burnt quicklimes (CaO...
