OBJECTIVE Lime has a long history as a contraceptive and vaginal hygiene douche, and ongoing use in Africa is documented. We report on the first safety study on diluted lime juice to assess its potential as a candidate microbicide. METHODS Twenty-five sexually abstinent women were randomly assigned to apply a 10% or 20% concentration of lime juice or 0% (water-only) through a soaked tampon on...

Corn stover was pretreated with lime and shock, a mechanical process that uses a shockwave to alter the biomass structure. Two pretreatments (lime-only and lime + shock) were evaluated using enzymatic hydrolysis, batch mixed-culture fermentations, and continuous countercurrent mixed-culture fermentation. In a 120-h enzymatic hydrolysis, shock pretreatment increased the glucan digestibility of s...

Gypsum is being applied to ameliorate subsoil acidity and to overcome the problem of very slow lime movement from surface lime applications. Reduced Crude Conversion Spent Lime (RCCSL) containing anhydrite was evaluated for use as a liming material with specific consideration given to the movement of sulfate into the acid subsoil. Agricultural lime and RCCSL were applied at 0, 0.5, 1.0, and 1.5...

Despite the attention focused on click and mortar strategies, little empirical work has directly addressed the sources of competitive advantage of this approach, nor the factors that distinguish between a successful and unsuccessful implementation. In this paper, we review theoretical work that establishes the basis for expecting synergy between e-commerce and physical presence in a market. We ...

After the tide of the Internet and impact of the Internet bubbled, E-Commerce business models have moved toward the click-and-mortar business models which could improve the revenue for keeping survival. This study is to explore the relationship between the click-and-mortar model and its performance based on the innovation approach. From the innovation perspective, three dimensions of the click-...

This paper presents the experimental results of the investigation of various properties related to the durability and longterm performance of mortars made of Fly Ash blended cement, FA and Ordinary Portland cement, OPC. The properties that were investigated in an experimental program include; equilibration of specimen in different relative humidity, determination of total porosity, compressive ...

*Correspondence: Xun Yu, Department of Mechanical and Energy Engineering, University of North Texas, Denton, TX 76203, USA e-mail: [email protected] Sodium dodecyl sulfate (SDS) and sodium dodecylbenzene sulfonate (NaDDBS) were used as surfactants to disperse multi-walled carbon nanotubes (MWNT) in cement mortar and fabricate pressure-sensitive carbon nanotubes filled cement mortar composites. The...

We consider a second order elliptic problem with a heterogeneous coefficient written in mixed form. The nonoverlapping mortar domain decomposition method is efficient in parallel if the mortar interface coupling space has a restricted number of degrees of freedom. In the heterogeneous case, we define a new multiscale mortar space that incorporates purely local information from homogenization th...

Mixtures of mineral aggregate and modified sulfur, wherein the modified sulfur functions as a binder, are termed sulfur concretes or sulfur mortars depending on the form of the mineral aggregate. Molten sulfur reacted with olefinic additive, at 130-140 ºC, and then mixed with preheated filler and aggregates. Sulfur mortar samples were prepared by mixing 32 % molten sulfur, 10 % filler and 5...

Tailing incorporation into mortars has been the subject of much research in recent years. Despite this, most these studies did not investigate harmful effects resulting from exposure such to an environment containing aggressive agents. This work investigated perlite tailing addition cement CP V-ARI MAX and hydrated lime. The raw materials were subjected chemical characterization (X-ray fluoresc...
