Indian industries use water in a very high quantity as compared to other countries' water usage. Inefficient water use by industries in India creates a lot of problems. This quantity could be reduced to a minimal by recycling the water after sufficient treatment. This work aims at sufficient in-situ treatment of wastewater and recycling of water for low-grade applications in the industry. Complete destruction of the contaminant is possible using inexhaustible, free source of energy from sunlight thus consuming very less primary energy for its operation. Photocatalytic experiments were carried out using laboratory photo reactor for degradation of phenol wastewater. The experiments were carried out with 0.2 g/l of TiO2 catalyst for different concentration of phenol wastewater ranging from 100, 300 and 500 ppm. It is found that complete degradation of phenol is possible in a reasonable time (i.e. less than 5 hrs) when concentration of phenol is ≤100 ppm.
We propose a method for synthesizing get‐up motions for physics‐based humanoid characters. Beginning from a supine or prone state, our objective is not to imitate individual motion clips, but to produce motions that match input curves describing the style of get‐up motion. Our framework uses deep reinforcement learning to learn control policies for the physics‐based character. A latent embedding of natural human poses is computed from a motion capture database, and the embedding is furthermore conditioned on the input features. We demonstrate that our approach can synthesize motions that follow the style of user authored curves, as well as curves extracted from reference motions. In the latter case, motions of the physics‐based character resemble the original motion clips. New motions can be synthesized easily by changing only a small number of controllable parameters. We also demonstrate the success of our controllers on rough and inclined terrain.
The present work pertains to synthesis, kinetic behavior and mechanism of hydrolysis of some organophosphorus pesticides. The compound investigated here was 2,5-diethoxyaniline in particular. The corresponding tri-phosphate ester was prepared in the laboratory by phosphorylation with POCI 3 . The process involved is that of the substitution of -OH group of orthophosphoric acid by aryl radical. The kinetics of the hydrolysis of the above ester was studied in acidic media. The acid employed was HCI. In acidic media, hydrolysis was carried out at three different temperatures 80, 90 and 98 0 C (keeping other parameters of the experiment unchanged). The rate of hydrolysis is found to follow the Arrhenius equation. The values of the Arrhenius parameters-energy of activation and change of entropy-point to the bimolecular nature of the hydrolysis of the triester. It can be inferred from the ionic strength data in the range 0.01 to 5 M-HCI, the reactive species of the present triester is conjugate acid species. Effects of temperature, and solvent on the rate of reaction, together with the correlation of rates with acidity and Bunnett parameters favour bimolecular nature of hydrolysis. The above results lead to the following most probable route of hydrolysis. In the case of triesers, dioxane was already present as constituent of the solvent. Experiment was repeated at three different dioxane concentrations in each case. The analysis of these data led to the interpretation that a transition state is formed with charge dispersed out of the reactive species and water and that the hydrolysis is a bimolecular nucleophilic reaction. The theoretical part of the present work includes calculation of the various terms involved in the mathematical formation of Hammett, Zucker and Hammett, Bunnett and Bunnett and Olsen hypothesis. This part supports the interpretation of the experiment results regarding the molecularity of the reaction.
