The phrase "activities killing" is not correct and does not convey a clear meaning in written English.
It may be intended to describe activities that are harmful or detrimental, but it lacks clarity and proper grammatical structure.
Example: "The activities killing the environment must be addressed immediately."
Alternatives: "harmful activities" or "destructive actions".
Taxes levied on harmful activities kill two birds with one stone.
Semen from males with more colorful bills harbored the greatest antibacterial activity, killing up to three times more bacteria than those with duller bills, the team reports online today in Biology Letters.
The compounds have anti-nematicidal activity, killing the nematodes Caenorhabditis elegans and Meloidogyne incognita.
Similarly, endosome-disrupting PBAE NPs alone had easily detectable, though modest cytotoxic activity, killing ∼75% of the tumor cells following 24 h treatment with 37.5 μg/mL NPs, consistent the sensitivity of tumor cells to endosome disruption.
Giants rifts in the land and an upsurge in violent volcanic activity killed off many of the major vertebrates, including large amphibians, leaving space for the dinosaurs to rise to prominence.
The titanium nano dispersion photocatalytic activity kills bacteria, when it is illuminated by light with energy higher than its band gaps and the electrons in titanium dioxide jump from the valence bond to the conduction bond.
The hydroxyapatite sample with the highest content of silver has shown the highest antimicrobial activity; killed all cells of E. coli and brought to more than 99% reduction in viable counts of S. aureus and C. albicans.
In addition, neutrophils from mice with defective NADPH-oxidase activity kill inefficiently ingested Staphylococcus aureus both in vitro and in vivo (Ellson et al., 2006), and inhibiting the production of reactive oxygen species in human neutrophils (e.g. in hypoxic conditions) impairs intracellular killing of S. aureus (McGovern et al., 2011).
Regular physical activity kills two birds with one stone -- it can boost "good" cholesterol while simultaneously lowering "bad" cholesterol and triglycerides.
