Delta-Valerolactone, with the chemical formula C5H8O2, has the CAS number 542-28-9. It appears as a colorless liquid with a sweet, fruity odor. The basic structure of delta-Valerolactone consists of a five-membered ring with an oxygen atom and a methyl group attached. This compound is mis...
and lack water-solubility. CREMOPHOR is obliged to be used as a dissolution aid, but since CREMOPHOR causes severe allergic symptoms, a pretreatment of histamine H1/H2 antagonists is indispensable, which requires complicated operations at administration in the clinical environment. Furthermore, there ar...

Typically, this process occurs in the coastal aquifers during active seawater intrusion or dissolution of NaCl salts in presence of exchangers with exchange sites in equilibrium with freshwater (Han et al., 2014; Cobaner et al., 2012; Petalas and Lambrakis, 2006; Chen and Jiao, 2007). This ...

In this formula, 𝑞∈[0,1]q∈[0,1] and the larger 𝑞q represent the stronger explanatory power of the driving factor X on Y; h is the stratification or classification of the variable Y or factor X; 𝑁ℎNh is the number of units in the h layer; N is the unit number for ...
The δ37Cl value (−0.12 to +0.79) and the Cl/Br ratio (4076 to 9853) show that dissolution of late cretaceous marine halite layers, atmospheric precipitation, and water–rock interactions between volcanic rocks, mudstones, and sandstone can restrict the δ37Cl values in saline springs. ...
