The present focus of ' research these days is to find an alternative lr these fossil fuels. Cultivation ol miCroalLae in wastevatcr sources ncli in nitroiien and phosplirus for bioniass production and later hiodiesel production from the extracted lipids have found to he quite pi'oiiiiing in this regard. A large number of microalgae and several vastewater sources from municipal wastewater to industrial wastewater have been eniploved till now. This study deals with the use of Scenedesnius ahundans in two di l'trent media viz. BC- Il and BBI\I 19 along with two different sources of wastewater viz, sewage wastewater from Saharanpur %IunicipaI \Vastewater Treatment Plant and Star Paper \lill. Saharanpur. Two media were taken to check which gi es best result in acclimatized or nutrient sufficient media. Four dit't'erent combination of wastewater samples are made with the use of' both wastewater sources in the ratios (MWW I P\4WW 4, MMW 2 1 PMWW 3. MWW 3 PMWW 2. MMW 4 ± PMWW I ). Maxinium biomass were found in acclimatized media l'roni both the cultures. Water qual itv parameters were checked along with biomass production and lipid production for biodiesel production. BOD reduction was achie ed in the range of' X7.1 6 to 90.29 0 and ('OD redLiction was obtained between 76.8' to 80.58 N utrient i'emo\ il was observed between 48- 2 00 for phosphate and 7- I o for nitrate.

The biopolymer used in the present work was chitosan. The influence of various operating parameters which were: initial chitosan concentration (mglg PCC), contact time (5mm. -5 hr), and temperature (30°C - 80°C) were investigated. The adsorption of chitosan on PCC surface was analyzed by measuring total organic carbon (TOC) of the supematant The equilibrium data obtained was analyzed for isotherm study using famous Langmuir and Freundlich isotherm models. The kinetics of the experiment was studied using pseudo-first order and second-order kinetic models. Field emission scanning electron microscope (FESEM), X-ray diffraction were carried out to characterize the PCC before and after adsorption. After that the application of chitosan modified as well as unmodified PCC in paper was investigated. 70 gsm handsheets containing no filler and 15% filler (each modified and unmodified) were prepared and tested for various strength properties, optical properties and ash content. 2016-05-01T00:00:00Z http://localhost:8081/jspui/handle/123456789/18753 Title: "TO DEVELOP A HIGH SPEED PRINT SYSTEM FOR TRANSFER PRINTING FOR A INCOMPATIBLE PACKAGING MATERIAL SURFACE Authors: Singh, Kartikey Abstract: Printing is one of the most essential components of packaging material. It is often necessary to modify the surface for printing some time it require a special surface. Despite all these efforts some surfaces are difficult to print. It had been a serious problem for years to print such surfaces. Advent of transfer printing reduced this problem and today most of the surfaces are readily printable. However, printing is often done on a separate sheet or surface and attached to the molded packaging or container. This increases the cost of material and operation. Further there is a need of a totally printing section to take care of it. It is a lacuna that needed to be addressed. Present work is a step to overcome the lacunae .Transfer printing with thermal energy is a technology that has progressed towards it. Transfer printing is a technology of transferring the print from one surface to another by exciting the transfer process which otherwise remains inactive. One of process of activation is thermal. Heat and pressure are applied on the surface to be transferred and the print gets transferred from a pre printed surface. This project aims to utilize this process of thermal printing and transfer of print from one of the substrate to another. The film is casted on a supported film and the support gets detached during transfer. The whole set of operation that needed in present case is a print supporting surface, an adhesive layer and a print layer The technology of print layer is well documented and practiced, supportive layer is also known as it tattoo only a reactive adhesive layer to be activated during contact with required substrate needed to be designed The objective of present work is to develop the adhesive layer 2016-05-01T00:00:00Z http://localhost:8081/jspui/handle/123456789/18752 Title: EXPERIMENTAL MODELING AND SIMULATION OF ORGANIC COATING OVER BANANA PEEL TO INCREASE SHELF LIFE BANANA Authors: Singh, Yogender Abstract: Banana is highly perishable material and nearly 30-40% of banana grown in India get spoiled and causes growth of microorganism. Reason behind this decomposition is diffusion of various gases / organic liquids through the banana skin protecting the inner carnal. Once transport of molecules through banana skin is slowed down more resistive it will increase life of banana. Mostly different types of hygienic chemicals are treated on top of the skin and it stops diffusion of molecules. We come out with three different chemical solutions and treat ripe banana to estimate how life can be extended. Atmospheric oxygen is mainly responsible for banana ripening which comes in through banana thin porous reactive peel and reduce it's shelf life. Diffusion of this compound through flat virgin banana skin and treated (edible contained protective solutions) banana skins were tested. It is noted that (Aleo Vera based) selection as coating material can minimize the microbe growth. Concentration and flux distribution of oxygen through banana peel is studied with the help of simulation software which help in increasing shelf life of banana. The model showed wonderful prediction oxygen diffusion in porous banana peel. 2016-05-01T00:00:00Z
