In urban areas of low-income countries, treatment of faecal sludge (FS) is insufficient or non-existent. This results in large amounts of FS being dumped into the environment. Existing treatment technologies for FS, such as settling-thickening tanks and drying beds, are land intensive which is limiting in urban areas. Enhanced settling and dewatering by conditioning was evaluated in order to re...

BACKGROUND Fires, explosions, and extreme heat production may occur when sevoflurane reacts with desiccated barium hydroxide lime. The identity of the flammable gas has not previously been published, although carbon monoxide, methanol, formaldehyde, and methyl formate have been identified in low quantities. METHODS The authors reacted sevoflurane with excess desiccated barium hydroxide lime o...

The Jamshoro soil is a weak and expansive soil. construction of infrastructure on such soils has resulted severe damages huge maintenance costs. Thus, it needs treatment to enhance its geotechnical properties. This research work investigates the effects chemical stabilizers as lime, fly ash, silica fume compaction consolidation characteristics Jamshoro. were added individually in different prop...

Long-term improvement in behaviour of soil subjected to lime treatment depends on the mechanism its implementation. In-situ lime-treated fine-grained is often ‘kneading action’ developed by Pad-foot roller. The underlying effect kneading remains less investigated. Unconfined Compressive Strength (UCS) and microstructural modification compaction are evaluated. Kneading action undergoes better li...

The objective of the study was to evaluate the perception of lime factory workers regarding work-related health-disease process. Data were collected from ten workers through non-structured observation and semi-structured interviews conducted in lime factories in the state of Ceará, Northeastern Brazil, in December 2005. Lime workers did not perceive themselves as being at risk for serious healt...

the objective of this research is to investigate the effect of four additives including iron slag (is), works debris (wd), fly ash (fa), and lime kiln dust (lkd) on the biochemical properties of biosolids produced at mangere wastewater treatment plant (mwwtp), auckland, new zealand. all these additives are homogenously mixed in the laboratory with biosolids at various percentages with and witho...

Because of sexual propagation of Mexican lime in southern regions of Iran, there are many lime accessions (lime biotypes) in Mexican lime gardens in which appear some variation in fruit and tree shape. However, most of these accessions are susceptible to witches broom disease of lime (WBDL). Persian lime (C. latifolia Tanaka) is a triploid WBDL-tolerant species. Considerable number of un-descri...

Spent lime is a by-product of the sugar beet sugar purification process. It is generated by heating mined calcium carbon limestone to form calcium oxide and carbon dioxide. These two products are injected into the thick juice (from the sugar beet processing) and reforms calcium carbonate. When the calcium carbonate reforms it captures or adsorbs many of the impurities in the juice and precipita...

In the paper some results on the effects of chemo-physical evolution of clay-lime-water suspensions on the microstructure of a lime treated kaolin have been presented. A multi-scale investigation on the sedimentation behaviour of clay suspensions under different pore water chemistry has been developed highlighting the chemophysical mechanisms controlling particle arrangement and the soil fabric...
