Background Phenols are chemical compounds which are included in the high priority of pollutants by environmental protection agency (USEPA). The presence of high concentrations of phenols in wastewaters like oil refineries, petrochemical plants, olive oil, pesticide production and oil field operations contain high soluble solids (TDS) and in an olive oil plant, wastewater is acidic, high salty a...

This work aims to study the production of the biomass of S. cerevisiae on an optimized medium using date extract as the only carbon source in order to obtain a good yield of the biomass. The biomass production was carried out according to the central composite experimental design (CCD) as a response surface methodology using Minitab 16 software. Indeed, under optimal biomass production conditio...

We study the quantum phase transitions of spin-1 Heisenberg chains with an easy-axis anisotropy $\Delta$ and a uniaxial single-ion $D$ using multipartite entanglement approach. The genuine tripartite between spin blocks, measured by qutrit hyperdeterminant, is calculated within renormalization group method. Using this approach, boundaries topological Haldane, large-D anti-ferromagnetic N\'eel p...

In 1959, Jacques Monod wrote a manuscript entitled Cybernétique enzymatique [Enzymatic cybernetics]. Never published, this unpublished manuscript presents a synthesis of how Monod interpreted enzymatic adaptation just before the publication of the famous papers of the 1960s on the operon. In addition, Monod offers an example of a philosophy of biology immersed in scientific investigation. Monod...

this paper investigates the importance of considering biomass growth and decay for predicting a field scale microbial degradation of btex plume in an unconfined aquifer system in the pump station area of tehran oil refinery (tor), iran. a two-dimensional finite volume model has been presented to predict multi-species reactive transport incorporating physical, chemical and biological processes i...

As emphasized by Hills (1,2), there are two basically different approaches to decompression optimization. The first is to devise a convenient calculational method and then modify it empirically until it is in reasonable agreement with the available data. The second is to develop a theoretical model from fundamental physical and physiological principles and then attempt to quantify its response ...

As an introduction to my topic, let me quote from the 1970 bestseller, Chance and Necessity, by the late Jacques Monod. In this “essay on the natural philosophy of modern biology”, as the book is subtitled, the celebrated French biologist attempted, as many have done before and after him, to derive some sort of Weltanschauung from the science of his day. On the existence of intelligent life on ...

Jacques Monod, born 100 years ago, was one of the main founders of molecular biology. A quotation of Roger Stanier seems to me of immediate relevance to the topic of this meeting on ‘‘Chance and necessity in evolution,’’ dedicated to the works of Jacques Monod: ‘‘Jacques Monod, one of the great scientists of the twentieth century, will always have an honored place among the leaders of the secon...
