ABSTRACT
The quantum of plastic waste in municipal solid waste (MSW) is increasing due to increase in population, urbanization, development activities and changes in life style which leading widespread littering on the landscape. Thus disposal of waste plastic is a menace and become a serious problem globally due to their non-biodegradability and unaesthetic view. Since these are not disposed scientifically & possibility to create ground and water pollution. This waste plastic partially replaced the conventional material to improve desired mechanical characteristics for particular road mix. In the present paper developed techniques to use plastic waste for construction purpose of roads and flexible pavements has reviewed. In conventional road making process bitumen is used as binder. Such bitumen can be modified with waste plastic pieces and bitumen mix is made which can be used as a top layer coat of flexible pavement. This waste plastic modified bitumen mix show better binding property, stability, density and more resistant to water.

Authors: Shekhar Pandharipande*, Harshal Makode

JERS/Vol. III/ Issue II/April-June, 2012/06-09

ABSTRACT
An orange, specifically, the sweet orange (Citrus sinensis (L.)) is the most commonly grown tree fruit in the world. The present work addresses to the development of the part of the process needed for the extraction of value added products i.e. orange oil and pectin from orange peel, which is the waste of orange juice processing industry & revealed that the sweet orange peels are good source of orange oil and pectin and does have the potential to become important raw material for food processing industries. Two methods, simple distillation & leaching, have been explored for separation of oil from peels..The remains of cake in this part is further treated for isolation of pectin. It is found from the experimental observations that the peel source, for extraction of pectin, when taken after extracting orange oil through simple distillation gives higher yield than leaching residue. So it can be concluded that the process in which orange oil is first extracted using technique of simple distillation followed by acid extraction of pectin is most suitable for industrial production for isolation of pectin. These results demonstrate the successful extraction of orange oil and pectin, providing potential benefits for industrial extraction of pectin from an economic and environmental point of view.

Authors: Mr Dendge Ramesh R*, Prof. R. G. Kaduskar

JERS/Vol. III/ Issue II/April-June, 2012/14-16

ABSTRACT
Screen-printing offers high ink deposition on a variety of substrate. This is major plus of this printing technology compared to offset, flexography and gravure. Owing to developments in mesh manufacturing technology, now we can comfortably print half tone with resolution of 100 LPI (Lines per Inch) and above. This has helped screen printer to reproduce monochrome continuous tone and full color graphic original, matching performance of other printing technologies. Parameters such as mesh count, mesh tension, screen frequencies are to be considered in printing the best half tone image. There are several aspects within the screen-printing systems that affect the print characteristics viz. dot shape and screen angle. In addition, the rheological of the printing ink is a key factor that can influence the consistency of the ink film thickness.

Authors: Mr Dendge Ramesh R*, Prof. R. G. Kaduskar

JERS/Vol. III/ Issue II/April-June, 2012/17-19

ABSTRACT
Unlike peer printing technologies Screen Printing basically has been the dominant method of thick ink film deposition. In 1990s onwards a growing need for denser packaging and a drive for higher pin count, screen-printing has been evolved to offer high-resolution printing. But, fine line printing and half tone printing as needed in case of full color graphic original’s reproduction demand stringent controlling of mesh and stencil related screen-printing process variables. It is very important in fine line and half tone screen-printing that the ink deposition is consistent and controlled as it affects the color appearance considerably. Of all influential factors ink deposition is largely governed by mesh and stencil system. Study of effect of threads per centimeter count, thread diameter, type of weave of the mesh and EOM (Emulsion over Mesh) of stencil system parameters on ink deposition is carried out with Color difference i.e. ∆Ebb as response factor. The implementation procedures of the experimental design are also presented.

OPTIMIZATION OF CRYOGENIC TREATMENT TO MINIMIZE THE FLANK WEAR OF AISI M2 HIGH SPEED STEEL TOOLS BY TAGUCHI TECHNIQUE

Authors: Simranpreet Singh Gill

JERS/Vol. III/ Issue II/April-June, 2012/28-33

ABSTRACT
Deep cryogenic treatment (DCT) is the process of deep-freezing tool steels at cryogenic temperatures to enhance the wear resistance. The tool steel is gradually cooled down to the cryogenic temperature, after which it is held at that temperature for a particular period of time and is heated back to room temperature at a sluggish rate followed by low temperature tempering. The assorted levels of controllable DCT process parameters have their individual consequence upon the wear resistance of the tool steels. In present study, the Taguchi technique has been used to optimize the controllable DCT process parameters for AISI M2 high speed steel (HSS) turning tools to maximize tool life by minimizing flank wear. The commercially available square shaped AISI M2 HSS bits were procured and grinded on tool and cutter grinder to obtain tool signature as per IS:3019-1973 for turning tests. Interaction between tool flank wear and controllable DCT process parameters cooling rate, soaking temperature, soaking time, tempering temperature and tempering time have been established by using Taguchi technique. The Taguchi design results confirmed that soaking temperature appreciably reduces the flank wear with contribution of 72.04%, followed by soaking period with contribution of 23.78%. The third major factor was cooling rate with contribution of 9.54%. The least significant factor acknowledged was tempering temperature with contribution of 2.74% whereas tempering period was found out to be trivial. Affirmation tests were conducted afterward, and the results obtained at identified optimum levels of process parameters were found to be within the confidence interval.

MACHINING PERFORMANCE OF CRYOGENICALLY TREATED AISI M2 HIGH SPEED STEEL TOOLS

Authors: Simranpreet Singh Gill

JERS/Vol. III/ Issue II/April-June, 2012/45-49

ABSTRACT
Results in literature show microstructural changes in the cryogenically treated high speed steel (HSS) tool materials that can influence tool lives and productivity significantly. However, the real machining performance of cryogenically treated HSS tools in actual turning process has not been reported in any candidly accessible study. In order to understand the effect of cryogenic treatment on HSS tools, a comparative investigation on machining performance of cryogenically treated AISI M2 HSS tools in orthogonal turning has been carried out in this study. The commercially available square shaped AISI M2 HSS bits were procured and grinded on tool and cutter grinder to obtain tool signature as per IS:3019-1973. Two groups of tools thus obtained were subjected to cryogenic treatment at two levels of −110 °C (shallow treatment) and −196 °C (deep treatment) independently in addition to traditional heat treatment and then the turning tests were executed in accordance to the International Standard Organization, ISO: 3685-1993. The criterion selected for determining the turning performance was based on the maximum tool flank wear (0.6 mm). The results showed that cryogenically treated AISI M2 HSS tools performed significantly better and the benefit achieved was considerably more in deep cryogenically treated tools as compared to shallow cryogenically treated tools.

FOUNDATION ISOLATION FOR SEISMIC PROTECTION USING SYNTHETIC LINER

Authors: Gohil D.P. Dr. C.H. Solanki. Dr. A.K. Desai

JERS/Vol. III/ Issue II/April-June, 2012/54-56

ABSTRACT
Base isolation and other structural control systems are being developed to reduce seismic structural response, thus minimizing damage. Now the use of reinforced soil to mitigation and reduction of induced ground shocks is research topic. Friction coefficients between various geosynthetic materials can change significantly with sliding velocity, which also is referred to as slip rate. During sliding, induced by an earthquake excitation, the slip rate between the interfaces may vary substantially. The dynamic response of a building foundation on reinforced soft soil is much more complex due to the effect of the inertial forces induced by the upper story masses. A restoring force can be provided in a building by passive resistance of the soil surrounding the foundation of the building. It is observed from the result that the earthquake energy transferred to structure due to soil-geosynthetic-structure interaction is reduced.

Authors: Prof. A.V. Prabhugaonkar, Prof. D.S. Bankar, Dr. D.B. Talange

JERS/Vol. III/ Issue II/April-June, 2012/72-76

ABSTRACT
Wind is one of the most widely used non conventional source of energy. Voltage stability is one of the main issues to have uninterrupted operation of wind farms equipped with doubly fed induction generators (DFIGs) during grid faults. Wind power plants are required to have active and reactive power control, frequency and voltage regulations and certain grid fault ride through capabilities. A successful low voltage ride through (LVRT) scheme is the main requirement for reliable and uninterrupted power generation for wind turbines equipped with DFIG. To enhance LVRT capacity a feed forward current control scheme is used for rotor side converter of DFIG. This conventional current regulator simulation analysis is performed using PID controllers in MATLAB.

Authors: J. Hussain, K. Palaniradja, N. Algumurthi

JERS/Vol. III/ Issue II/April-June, 2012/77-81

ABSTRACT
To meet stringent automotive exhaust emission norms worldwide, several exhaust pre-treatment and post treatment techniques have been employed in modern engines. Exhaust Gas Recirculation (EGR) is being used widely to reduce and control the oxides of nitrogen (NOx) emission from diesel engines. EGR controls the NOx because it lowers oxygen concentration and flame temperature of the working fluid in the combustion chamber. However, the use of EGR leads to a trade-off in terms of soot emissions moreover it exhausted more unburned hydrocarbons (20-30%) compared to conventional engines. Present experimental study has been carried out to investigate the effect of EGR on emissions in a three cylinders, air cooled and constant speed direct injection diesel engine, which is typically used in agricultural farm machinery. Such engines are normally not operated with EGR. .The present experimentation was carried out with and without insertion of unburned Hydrocarbons (which was drawn from the exhaust) in a EGR fitted compression ignition engine. The experiments were carried out to experimentally evaluate the emissions for different EGR rates of the engine. Emissions of hydrocarbons (HC), NOx, carbon monoxide (CO), exhaust gas temperature, and smoke opacity of the exhaust gas etc. were calculated. Reductions in NOx and exhaust gas temperature were observed but emissions of particulate matter (PM), HC, and CO were found to have increased with usage of EGR. The engine was operated for normal running conditions with EGR and the performance and emission readings were observed.
