We show that one-dimensional nonlocal flow models in PDE form with Lighthill-Whitham-Richards flux supplemented appropriate in- and out-flow terms can be spatially discretized a finite volume scheme to obtain formally kinetic physically meaningful reaction graph structure. This allows the utilization of theory chemical networks, as demonstrated here via stability analysis model circular topolog...

The study of transcription remains one the centerpieces modern biology with implications in settings from development to metabolism evolution disease. Precision measurements using a host different techniques including fluorescence and sequencing readouts have raised bar for what it means quantitatively understand transcriptional regulation. In particular our understanding simplest genetic circu...

Introduction: Using bio-sorbents is regarded as one of the effective methods to remove heavy metals. Therefore, this study aimed to investigate Pb adsorption from contaminated water by Chaetoceros sp. and Chlorella sp. algae. Methods: This experimental study was conducted in a batch reactor. The amount of Pb adsorption by Chaetoceros sp. and Chlorella sp. algae was studied under such conditio...

Pollution of water resources by various pollutants is nowadays a global environmental issue. Among the different type of water pollutants, dye represents a major polluting group. In this study, Azolla filiculides roots have been used for adsorption of Malachite Green (MG), a cationic dyed from aqueous solution. In this study, effects of operating parameters such as initial concentration of dye ...

Background: Investigating the performance of naturally operated treatment plants may be due to the fact that they cannot be operated as desired, or that they should be modified to achieve good performance e.g. for nutrients removal. The advantage of kinetic coefficient determination is that the model can be adjusted to fit data and then used for analyzing alternatives to improve the process. Th...

Introduction: Di (2-ethylhexyl) phthalate is one of the most abundant phthalate esters and it is widely used as softeners in plastic products. Malformation, carcinogenicity, the poisoning of the reproductive system, and also the disruption of the human endocrine system are the harmful effects of these substances. Materials and Methods: In this research, the removal of di (2-ethylhexyl) phthal...
