Mitigating antibiotic pollution using cyanobacteria: Removal efficiency, pathways and metabolism

“…Microalgal-based wastewater treatment offers the advantage of, in addition to the elimination of the pollutant, potential biomass re-utilization, e.g., as biofuel, biochar, or fertilizer (Kim et al, 2012;Miao et al, 2004). Therefore, during the experiment, we further investigated changes occurring to the biomass, due to tetracycline exposure.…”

X-ray line signal from decaying axino warm dark matter

“…where f a is the Peccei-Quinn breaking scale, and α s , G, G µν and α Y , Ỹ , Y µν are the gauge couplings, gaugino fields and the field strength for SU(3) c and U(1) Y gauge groups respectively. The mass of axino is expected to be of the order of gravitino mass, but it can be much smaller [19][20][21][22][23][24], or much larger [25] than the typical supersymmetric particle mass scale, depending on the specific models [26]. Here we take the light axino mass of the order of keV as dark matter component.…”

Dark radiation constraints on mixed Axion/Neutralino dark matter

“…3 show that in order to violate the CMB constraint on dark radiation (∆N ef f < 1.6), the axino needs to be at least two orders of magnitude heavier than the saxion, if ξ = 1. This is hard to achieve on most supersymmetric PQ models, where typically mã ≤ m 3/2 ∼ m s [17]. For smaller ξ values, ∆N ef f increases but it is still below the CMB bound as long as mã m s .…”

“…In gravity-mediation (as assumed in this paper) the saxion is expected to gain mass m s ∼ m 3/2 , where m 3/2 is the gravitino mass. More generally, the axino mass can range from keV to m 3/2 [15,16,17]. Here we always assume m ã ∼ m 3/2 [18], so the lightest suspersymmetric particle (LSP) is the neutralino.…”
