The present article focuses on the phycoremediation of pollutants from secondary treated coke-oven effluent through a green and economical route. A microalgal sample was collected and identified as a consortium of Chlorella sp. and Synechococcus sp. The culture cost was reduced by using poultry litter extract as supplementary material to BG-11 medium. Since major pollutants as present in real secondary treated coke-oven wastewater are phenol, ammoniacal-N (NH4+) and cyanide, several matrices were designed with these three major pollutants by varying their initial concentrations such as phenol (2–10 mgL−1), cyanide (0.3–1 mgL−1) and NH4+ (100–200 mgL−1), termed as simulated secondary treated coke-oven wastewater. Maximum removal was observed with individual solutions of phenol (4 mgL−1), cyanide (0.6 mgL−1), and NH4+ (175 mgL−1) while maximum removal in simulated secondary treated coke-oven wastewater was observed at higher concentrations of phenol (8 mgL−1) and cyanide (0.8 mgL−1) and the same concentration of NH4+ (175 mgL−1). Consortium was found effective to meet statutory limits of pollutants. Kinetic model was developed for predicting growth of consortium and observed that the poultry litter extract enriched BG-11 medium showed higher values of maximum specific growth rate (0.56 day−1) and carrying capacity (1,330 mgL−1) than that in BG-11 medium only.

We present an exploratory investigation of the parity odd Δ𝐼 = 1 pion-nucleon coupling ℎ 1 𝜋 from lattice QCD. Based on the PCAC relation, we study the parity-conserving effective Hamiltonian and extract the coupling by determining the nucleon mass splitting arising from the effective 4-quark interactions using the Feynman-Hellmann theorem. We present preliminary results of the mass shift for a 32 3 × 64 ensemble of 𝑁 𝑓 = 2 + 1 + 1 twisted mass fermions at pion mass 260 MeV and lattice spacing 𝑎 = 0.097 fm.

We present results for an exploratory lattice calculation of the leading parity-violating pion-nucleon coupling ℎ 1 𝜋 . Based on the PCAC relation we use a parity-conserving Lagrangian and focus on the techniques to determine the nucleon matrix elements of the effective 4-quark operators. For our study we employ an ensemble of twisted mass fermions with 260 MeV pion mass. Barring mixing with lower-dimensional operators and renormalization at this stage, we discuss our estimate for ℎ 1 𝜋 .
