The patient's diet has been considered an important etiological factor of dentin hypersensitivity. The frequent ingestion of acidic substances can promote the loss of dental structure or remove the smear layer. The purpose of this study was to evaluate the degree of smear layer removal and dentinal tubules exposure by different natural orange juices. Extracted human teeth were submitted to manu...

This paper presents the effect of sisal fibers on the unconfined compressive strength of bentonite. The present study is aimed at determining the behavior of bentonite-lime-phosphogypsum reinforced with sisal fibers in a random manner. The sisal fiber content was varied from 0.5 to 2 %. The results indicated that the unconfined compressive strength of bentonite can be increased by the addition ...

Treatment of tar-containing wastewater is necessary for the successful operation of biomass gasification plants (BGPs). In the present study, tar-containing wastewater was treated using lime and alum for the removal of in-organics, followed by adsorption on powdered activated carbon (PAC) for the removal of organics. Limealum experiments were performed in a jar apparatus and activated carbon st...

Areca nut is one of the most widely used psychoactive substances with several hundred million users worldwide, predominantly in southern Asia. Areca nut can be chewed alone or in a variety of ways that differ by region. The habit of chewing betel quid, containing fresh, dried or cured areca nut, catechu, slaked lime and flavouring ingredients wrapped in betel leaf, is widespread in India, Pakis...

Historical renders are exposed to several degradation processes that can lead to a wide range of anomalies, such as scaling, detachments and pulverization. Among the common anomalies, the loss of cohesion and adhesion are usually identified as the most difficult to repair; these anomalies still need to be deeply studied to reach compatible, durable and sustainable conservation treatments. The r...

Liming is a cost-effective treatment currently employed in many Class B biosolids production plants in the United States. A bench scale model of lime stabilization was designed to evaluate the persistence of viral, bacterial and parasitic pathogens. The survival of fecal coliforms, Salmonella, adenovirus type 5, rotavirus Wa, bacteriophage MS-2, Cryptosporidium parvum oocysts, Giardia lamblia c...

Soil fertility and crop production are affected by biological processes and these processes, including enzyme activites, are influenced by pH. We investigated the potential of using alkaline phosphatase (AlkP) and acid phosphatase (AcdP) activities, for determining the optimum soil pH for crop production and the amount of lime required to achieve this optimum. Five acid soils, which varied wide...

This is an in vitro study to evaluate five different commercially available citrus fruits: viz., Sweet orange (Citrus sinences Osbeck), Grape [Citrus maxima (J. Buruan) Merrile], Lemon [Citrus limon (Burn F.) and Lime (Citrus aurantifolia Swingle. Evaluation of their pHs and neutralizable acidity were made. A 50 mL of each fruit was prepared by juice press. Initial pH was measured in triplicate...

BACKGROUND: In addition to controlling sediment phosphorus in aquatic systems, lime (CaCO3 and Ca(OH)2) applications have been shown to be effective in both suppressing submersed macrophyte growth and changing species composition in a variety of ponds, small lakes, canals, and dugouts (Babin et al. 1992; Chambers et al. 2001; Prepas et al. 2001a, 2001b). The mode of action for controlling growt...
