This study was carried out to identify the conditions of formation of calcium sulphoaluminate (3CaO·3Al(2)O(3)·CaSO(4)) by the sintering of a limestone (CaCO(3)) and alunite [K(2)SO(4)·Al(2)(SO(4))(3)·4Al(OH)(3)] mixture with the following reagents: K(2)SO(4), CaCO(3), Al(OH)(3), CaSO(4)·2H(2)O, and SiO(2). When K(2)SO(4), CaCO(3), Al(OH)(3), CaSO(4)·2H(2)O were mixed in molar ratios of 1:3:6:3...

BACKGROUND AND AIMS The objective of this work was to determine the influence of the soil substrate on the characteristics and properties of a specific type of honey. As such, we analysed the features of a typical single-flower honey, thyme honey, produced in a specific Mediterranean region. Thymus is a genus of aromatic perennial plants that are native to Europe, North Africa and Asia. METHO...

The Swiss Jura is part of a larger region, the Jura, which stretches from Geneva to Germany, partly as a series of folds, partly as tablelands. The mountains were formed during the late phase of the Alpine folding during the Tertiary and are composed of Mesozoic rocks, mainly limestone and clay. The changing strata give way to a particular landscape, and the presence of limestone makes it a vas...

Introduction: The Yaxcopoil-1 (Yax-1) borehole, 60 km SSW of the center of the Chicxulub crater, penetrated through 600 m of sediments below the impactites (from about 894.9 m to the lowermost drilling depth of 1510.9 m). These rocks which are most likely of Cretaceous age are deformed to various degree and consist of distinct lithologies, predominantly carbonates and sulfates (dolomite, limest...

The rapidly increasing availability of electronic health records (EHRs) from multiple heterogeneous sources has spearheaded the adoption of data-driven approaches for improved clinical research, decision making, prognosis, and patient management. Unfortunately, EHR data do not always directly and reliably map to medical concepts that clinical researchers need or use. Some recent studies have fo...

In limestone calcined clay cements (LC3), more hemicarboaluminate and monocarboaluminate is observed, as compared to other blended cements, from the reaction of metakaolin with limestone. this study, it shown that formation these carboaluminate phases, predominantly occurs during a “third” hydration peak, after main alite aluminate peaks. The influence content, level sulfate addition water bind...

Story in Brief Two levels oflimestone (.7 and 2.0 percent) were fed with two levels of chopped alfalfa hay (10 and 50 percent) to 22 Hereford steers (517 lb). The diet also contained whole shelled corn and supplement. Animals were fed individually at a level equal to 2.5 percent of body weight daily in two equal meals. Organic matter, fiber and nitrogen digestibility were increased with added l...

Small-scale assimilation of limestone during the intrusion of an olivine basalt feeder dyke into an Eocene argillaceous, siliceous biomicrite in the Tokatoka area has resulted in the incorporation of large amounts of calcium into the parent magma. Initial effects of assimilation have caused partial resorption of the earlyformed igneous mineralogy and the precipitation of calcic, iron-rich clino...
