acute toxicity of alkali and alkaline earth metals on rohu, labeo rohita (hamilton) egg and hatchlings
the acute toxicity of salts of alkali and alkaline earth metals, such as sodium (na), potassium (k), calcium (ca) and magnesium (mg) were studied on the egg and larval stages of indian major carp labeo rohita (hamilton). the acute toxicity experiments were conducted followed by the range finding bioassay tests. the experiments were conducted in triplicates. the cumulative percentage of dead or ...
متن کاملPromoting alkali and alkaline-earth metals on MgO for enhancing CO2 capture by first-principles calculations.
Developing next-generation solid sorbents to improve the economy of pre- and post-combustion carbon capture processes has been challenging for many researchers. Magnesium oxide (MgO) is a promising sorbent because of its moderate sorption-desorption temperature and low heat of sorption. However, its low sorption capacity and thermal instability need to be improved. Various metal-promoted MgO so...
متن کاملFirst-principles solubilities of alkali and alkaline-earth metals in Mg-B alloys
In this article, we present a comprehensive theoretical study of solubilities of alkali Li, Na, K, Rb, Cs and alkaline-earth Be, Ca, Sr, Ba metals in the boron-rich Mg-B system. The study is based on first-principles calculations of solutes formation energies in MgB2, MgB4, MgB7 alloys and subsequent statisticalthermodynamical evaluation of solubilities. The advantage of the approach consists i...
متن کاملBond-length distributions for ions bonded to oxygen: alkali and alkaline-earth metals
Bond-length distributions have been examined for 55 configurations of alkali-metal ions and 29 configurations of alkaline-earth-metal ions bonded to oxygen, for 4859 coordination polyhedra and 38 594 bond distances (alkali metals), and for 3038 coordination polyhedra and 24 487 bond distances (alkaline-earth metals). Bond lengths generally show a positively skewed Gaussian distribution that ori...
متن کاملElectron capture dissociation of oligosaccharides ionized with alkali, alkaline Earth, and transition metals.
We extend the application of electron capture dissociation (ECD) (which requires at least two charges) to oligosaccharides without basic functionalities by utilizing alkali, alkaline earth, and transition metals (Na+, K+, Ca2+, Ba2+, Mg2+, Mn2+, Co2+, and Zn2+) as charge carriers in electrospray ionization. Both linear and branched oligosaccharides were examined, including maltoheptoase, p-lact...
