Reliability of organic and biogenic pollutant removal in selected technologies used in domestic wastewater treatment plants: A comparative analysis.

The results of a comparative study of two different technological solutions applicable to decentralised domestic wastewater treatment systems are presented. A hybrid reactor with activated sludge and mobile biofilm carriers moving in wastewater is one of them, and an innovative quasi-technical combination of a biological reactor with a sprinkled bed filled with sintered clay granules, followed in the process line by an innovative slope type filtration bed, is the other one. The study has shown a significant advantage of filter bed installations in functional quality, expressed in low values of indicators and pollutant concentrations.

STAT3 and Its Pathways' Dysregulation-Underestimated Role in Urological Tumors.

Nowadays, molecular research is essential for the better understanding of tumor cells' pathophysiology. The increasing number of neoplasms is taken under 'the molecular magnifying glass'; therefore, it is possible to discover the complex relationships between cytophysiology and tumor cells. Signal transducer and activator of transcription 3 (STAT3) belongs to the family of latent cytoplasmic transcription factors called STATs, which comprises seven members: STAT1, STAT2, STAT3, STAT4, STAT5A, STAT5B, and STAT6.

Kinetics of pollutants removal in vertical and horizontal flow constructed wetlands in temperate climate.

This paper reports a comparative study on kinetics of organic matter expressed as BOD and nitrogen removal in constructed wetlands operated in Poland. Analyzed data were collected at eight wetland systems, composed of subsurface flow beds: horizontal flow (HF) and vertical flow (VF), in different number and sequences. The analysis involved particularly mass removal rates (MRR) and first-order removal rate coefficients of BOD and total nitrogen (k and k for VF and HF filters, respectively, and k as a parameter averaged for a temperature of 20 °C).

Nitrogen removal in vertical flow constructed wetlands: influence of bed depth and high nitrogen loadings.

The aim of the study was to evaluate the nitrogen removal and its effects on the plant's growth and leaves morphology. using two subsurface vertical flow (VF bed), with different depths (0.24 m × 0.
