Acute and chronic toxicity assessments of 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) on the calanoid copepod Acartia clausi: Effects on survival, development, sex-ratio and... by Emna, Djebbi

“…Embryos showed non-monotonic dose-response and hatching success was significantly reduced at low realistic concentrations of E2 (0.005, 0.5, and 5 μg L-1) and EE2 (0.05 and 5 μg L-1).Survival, development and sex ratio of A. clausi to EE2 exposure at 1 and 100 μg L-1 were also determined during a life cycle experiment. …”

Improved mechanical properties of recycled linear low-density polyethylene composites filled with date palm wood powder by AlMaadeed, Mariam A.

“…The presence of filler increased the flexural strength from 11.4MPa for unmodified RLLDPE to 17MPa for the composite containing 70wt.% filler. The Young’s modulus and stress at break measured at 50°C decreased significantly compared with those values measured at 25°C. …”

Improved flexible, controlled dielectric constant material from recycled LDPE polymer composites by Noorunnisa Khanam, P.

“…In this study, recycled low density polyethylene (RLDPE) is developed with the addition of aluminum oxide (Al2O3) to have new polymer composites. The following wt% were used of the filler (1, 4 and 6 wt%). Tensile properties, Hardness, scanning electron microscopy (SEM) thermo gravimetric analysis, differential scanning calorimetry and dielectric properties were studied for these composites. 4 wt% Al2O3/RLDPE composites showed the optimum values of 15.52, 180.8 and 59.72 MPa for the tensile strength, tensile modulus and hardness were reported. …”
