Biological symmetry breaking is a mechanism in biosystems that necessary for human survival, and depends on chemical physics concepts at both microscopic macroscopic scales. In this work, we present few mechanisms of the signaling phenomenon have been studied various tissues origin. We exhibit anatomical asymmetry structure membrane can produce flow extracellular fluid. Furthermore, misbalance ...

Integrated Membrane Bioreactor (MBR) models, combination of biological and physical have been representing powerful tools for the accomplishment high environmental sustainability. This paper, produced by International Water Association (IWA) Task Group on Modelling Control, reviews state-of-the-art, identifying gaps future researches, proposes a new integrated MBR modelling framework. In partic...

statement of problem: there are limited histomorphometric studies on biologic efficacy of high density tetrafluoroethylen (d-ptfe) membrane. objectives: to investigate the healing of surgically induced grade ii furcation defects in dogs following the use of dense polytetrafluoroethylene as the barrier membrane and to compare the results with the contra lateral control teeth without the applicat...

A lab-scale SBR equipped with a flat sheet membrane in submerged configuration that is named MSBR was used for the treatment of composting leachate. It was fed by biologically treated leachate with overall 70-1360 mg/L Chemical Oxygen Demand (COD). The values of pH, Electrical Conductivity (EC), and Dissolved Oxygen (DO) were monitored r...
