Study objectives: Hypertonic saline solution inhalation is suspected to produce airway inflammation. Design: The aim of this study was to verify this hypothesis by measuring inflammatory markers in exhaled breath condensate (EBC) collected before and after sputum induction with hypertonic and isotonic saline solution. Patients and methods: We enrolled 10 patients with asthma, 10 patients with C...

India's northward flight and collision with Asia was a major driver of global tectonics in the Cenozoic and, we argue, of atmospheric CO(2) concentration (pCO(2)) and thus global climate. Subduction of Tethyan oceanic crust with a carpet of carbonate-rich pelagic sediments deposited during transit beneath the high-productivity equatorial belt resulted in a component flux of CO(2) delivery to th...

Hot-spring waters near the Main Central thrust in the Marsyandi River of central Nepal have Sr concentrations to 115 mM with 87Sr/86Sr to 0.77. Small amounts of hydrothermal water (#1% of total river discharge) have a significant impact on the solute chemistry and the budget of radiogenic Sr in the Marsyandi. In the upper Marsyandi, river chemistry reflects carbonate weathering, with 87Sr/86Sr ...

Eighteen commercial beers have been analyzed in both liquid and gas phases using colorimetric sensor arrays made from selected chemically responsive dyes printed on a hydrophobic membrane. Digital imaging of the dye array before and after exposure to the complex analytes in either the liquid phase or the head-gas provides a color change profile as a unique fingerprint for the specific analyte. ...

In the field of tourism, the development of tourist attractions is gradually playing a crucial role in tourism economy, regional economy and national economy. While tourism economy is stimulated by growing demand, tourist attractions have been facing the situation that ecological environment is becoming fragile and environmental protection is increasingly difficult in China. As low-carbon econo...

One of the major drawbacks that hinder the industrial competitiveness of the calcium looping (CaL) process for CO2 capture is the high temperature (∼930-950 °C) needed in practice to attain full calcination of limestone in a high CO2 partial pressure environment for short residence times as required. In this work, the multicycle CO2 capture performance of dolomite and limestone is analysed unde...

Limestone is a popular building stone worldwide. In Baku in Azerbaijan, local limestones have been used construction, including the walled historic city centre (Old City, Icherisheher). Located seismically-active area, prone to post-earthquake fires that can damage buildings and monuments. Here, we test fire resistance of limestone by measuring its physical (connected porosity, permeability, P-...

Coal mining and the energy industry generate large amounts of solid waste, which must be disposed in landfills lead to numerous environmental problems. This paper presents a method for creating artificial soil mixtures based on an EU-funded international research project called RECOVERY. The main idea behind proposed solution is safe use coal combustion by-products (energetic slag decarbonation...

The calcium-Looping process is an advantageous candidate for thermochemical energy storage in Concentrated Solar Power plants. Achieving fast thermal at a moderate temperature would be highly beneficial the heat process. In this study, commercially available alkali carbonates (Li2CO3, Na2CO3, K2CO3) were used as dopants limestone/dolomite to improve their decarbonation rates and cycling stabili...
