Different dosages of a commercialized potato starch were added to aerial lime-based mortars in order to check its efficiency as a rheological modifier. Several fresh state properties of the mortars were studied: consistency, density, air content, water retention capacity, setting time and evolution when applied on support. The effect of the starch on -potential of the lime particle surface as ...

The Middle Mississippian Delle phosphatic event marks a significant change in depositional conditions in the Devonian–Mississippian Antler foreland basin of North America. Stratigraphic and petrographic studies show that deposition of Delle-event rocks ended a long period of open-marine carbonate sedimentation when facies shifted to phosphorites, cherts, fine-grained siliciclastics, and lime mu...

Acidic (pH 4.1) and high Cd, Pb, and Zn mine tailings (mean +/- SD: 17 +/- 0.4, 3800 +/- 100, and 3500 +/- 100 mg kg(-1), respectively) from an alluvial tailings deposit in Leadville, Colorado were amended with municipal biosolids (BS) (224 Mg ha(-1)) and different types of lime (calcium carbonate equivalent of 224 Mg ha(-1) CaCO3) in a greenhouse column study to test the ability of the amendme...

Steelmaking slag is a by-product of steel making. It has been reused as a material for civil engineering, pavement construction etc. For such applications, it is extremely important to evaluate the amount of free lime, which has the chemical form of calcium monoxide (CaO) and can cause the failure of mechanical properties by volume expansion through absorption of water or carbon dioxide gas. So...

BAR-JOSEPH, M., S. M. GARNSEY, D. GONSALVES, M. MOSCOVITZ, D. E. PURCIFULL, M. F. CLARK, and G. LOEBENSTEIN. 1979. The use of enzyme-linked immunosorbent assay for detection of citrus tristeza virus. Phytopathology 69:190-194. An enzyme-linked immunosorbent assay (ELISA) test was used to seedling yellows isolates of CTV from Israel and from Florida. Isolates that identify citrus tristeza virus ...

Ethnic Identification, Intermarriage, and Unmeasured Progress by Mexican Americans Using Census and CPS data, we show that U.S.-born Mexican Americans who marry nonMexicans are substantially more educated and English proficient, on average, than are Mexican Americans who marry co-ethnics (whether they be Mexican Americans or Mexican immigrants). In addition, the non-Mexican spouses of intermarr...

Lime ball quality inspection is an important task in the pulp and paper industry. In this paper a new method, build-up on a neural network and a path search method, is introduced for lime ball automatic visual inspection. Several correction steps to Landau's method are also introduced.
