Laboratory kinetic leach column (KLC) tests were carried out to define the conditions required to control acid generation from a highly reactive, potentially acid-forming (PAF) iron ore waste rock. It was found that lime addition (0.1 wt % blended) plus either blending of silicates (25 wt % K-feldspar and 25 wt % chlorite), or addition of a non-acid forming (NAF) top cover containing about 10% ...

This study was carried out to evaluate the effect of spent oil contamination on the strength of lime stabilized soil. Laterite soil was stabilized with lime in percentages of 0, 2, 4, 6, and 8% of the dry weight of soil. Specimens were prepared for UCS and CBR. The specimens for UCS were cured for 7, 14 and 28 days; while the specimens for CBR were cured for 4 days. Contamination of the specime...

Lime flocculation/sedimentation in the first process unit of a 4,500-m3/day wastewater reclamation plant reduced numbers of microorganisms extensively when operated at pH 11.2. The efficiency was much less at lower pH values, and some bacteria even multiplied at pH 9.6. Data on reduction in the number of microorganisms in the lime treatment and subsequent units indicate that inactivation by hyd...

Abstract The cultivation of orange trees in Amazonas, Brazil relies predominantly on grafted plants combining ‘Pera’ scion and ‘Rangpur’ lime rootstock. Alternative rootstocks better adapted to the conditions region have not been investigated. Therefore, objective this research was test seven for production high-quality oranges under typical Amazon. Citrus evaluated from May August between 2017...

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 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...

in order to study radiation use efficiency and radiation interception in intercropping of herb sweet basil and common bean, an experiment was conducted at the agricultural research station, ferdowsi university of mashhad, iran for the growing season of 2008. treatments were 1) sole crop of bean , 2) sole crop of sweet basil, 3) strip intercropping of bean and sweet basil (four rows bean and two...

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...

As in several fruit crops, citrus trees with decreased size allow for a higher planting density, which may lead to productivity and facilitate operations such as harvesting spraying. The use of dwarfing rootstocks is one the most feasible methods tree control, but few commercial varieties are available date. In this work, long-term performance Valencia sweet orange grafted onto 51 hybrid was ev...
