Plastics have woven their way into our daily lives and now pose a tremendous threat to the environment. Over a 280 million tone's of plastics are produced annually worldwide, and the used products have become a common feature at overflowing bins and landfills. Here, the process of converting waste plastic into value added fuels is explained as a viable solution for recycling of plastics. Thus two universal problems such as problems of waste plastic and problems of fuel shortage are being tackled simultaneously. In this study, plastic wastes (low density polyethylene) were used for the pyrolysis to get fuel oil that has the same physical properties as the fuels like petrol, diesel etc. Pyrolysis runs without oxygen and in high temperature of about 300°C. The waste plastics are subjected to pyrolysis to obtain different value added fuels such as petrol, kerosene, and diesel, etc. Converting waste plasti...

Textile fibre1reinforced composites are more attractive1due to their high specific1strength, light weight and finding1increased applications in many engineering1fields especially in interior1construction of buildings.

Nowadays development of low-cost composites with preferable good mechanical properties is one of the major issues in research areas. The machining of composite materials faces various issues, for example, delamination factor and cutting variables. This paper presents the investigation of factors that impact the thrust force and delamination in the drilling of coconut leaf sheath reinforced composites by considering Taguchi's and ANOVA techniques. The material used for fabricating the composite materials are coconut leaf sheath and phenol formaldehyde resin. It is fabricated by using a hand layup method with 6 mm thickness. An orthogonal array of L9 is implemented and experiments were conducted. The test results have demonstrated that the rate of feed is seen to be more contributing to delamination and thrust force than cutting speed.

With an increasing amount of population exposed to whole body vibrations, a significant number of people experience fatal spine diseases. Substantial research is carried out to reduce the risk of spinal injuries. The dynamic characteristics of the cervical, thoracic and lumbar (CTL) region are studied extensively as individual sections of the spine. Few studies have focused on the CTL spine as an assembly of the three segments. In the present work, an authentic three dimensional geometrical model of the cervical, thoracic and lumbar spine is developed in mimics considering its natural curvature and the intervertebral discs are modeled in Design modeler. The natural frequency and mode shapes of the CTL spine are extracted using free vibration modal analysis considering 4.5 kg point mass on C1 vertebra and distributed mass of 40 kg on the CTL spine in Ansys Workbench. Six n...
