abstract the limitation of water sources in most places all over the world, especially in arid and semi-arid lands is an important issue for those who live in these areas. many governments have dedicated their efforts toward finding new water resources to obtain water. fog and cap clouds harvesting are one of the candidate methods to produce pure water. many countries including chile, peru, ecu...

Several studies have exploited the stable calcium (Ca) and strontium (Sr) isotope compositions of marine carbonate rocks to investigate ancient carbon cycle dynamics, seawater geochemistry, controls on production preservation. However, two proxies rarely been applied together. Based knowledge achieved date, δ44/40Ca-δ88/86Sr multi-proxy can distinguish signatures imparted by mass-dependent frac...

BACKGROUND Few studies describe the community-acquired pneumonia (CAP) burden in children in Asia. We estimated the proportion of all CAP hospitalizations in children from nine hospitals across the Republic of Korea (high-income), Indonesia, Malaysia (middle-income), and Vietnam (low/middle-income). METHODS Over a one or two-year period, children <5 years hospitalized with CAP were identified...

The wellbeing of marine organisms is connected to their microbiome. Oysters are a vital food source and provide ecological services, yet little known about how climate change such as ocean acidification warming will affect We exposed the Sydney rock oyster, Saccostrea glomerata, orthogonal combinations temperature (24, 28 °C) pCO2 (400 1000 ?atm) for eight weeks used amplicon sequencing 16S rRN...

Percolation experiments, using columns filled with alternating layers of hydrated Portland cement and crushed sedimentary rocks, were conducted at PCO2 = 10 bar 60 °C. Limestone, sandstone marl representative reservoir cap rocks for a geologic CO2 storage site. The injected solution was equilibrium gypsum equilibrated the CO2. main reactions dissolution calcite that constitutes hydrotalcite por...

Algal biorefinery process utilizes every component of algal biomass to produce multiple useful fuel products. In this technique, acid pretreatment of algal biomass hydrolyzes microalgal carbohydrates into fermentable sugars, makes lipids more extractable and a protein part accessible for additional products. In the present study, Chlorella sorkiniana produced higher quantity of biodiesel than B...

The rapid growth in natural gas consumption has increased the need for gas storage, in particular in the form of injection into depleted reservoirs. Also, CO2 sequestration into the depleted reservoirs has attracted a large attention recently. However, it is important to ensure that the injection pressure is maintained below a certain limit to avoid unsealing the cap rock or reactivation of any...
