The simarouba biodiesel is considered as one of the alternative fuels to diesel. This has been taken up to identify the performance characteristics by using Simarouba biodiesel. The depletion of world petroleum reserves and increased environmental concern have stimulated the search of alternative fuel which is to be environment friendly. Bio-fuels have the potential to become alternative fuel for fossil fuels. Biodiesel is renewable, reliable, biodegradable and regarded as a clean alternative fuel to reduce exhaust emissions. The simarouba biodiesel is considered as alternative fuels to diesel. The mainly is observed on the same factors which are critical to the potential profitable use of these blends. This paper investigates the performance using simarouba biodiesel on C.I.Engine.

Pages: 4 - 5
To develop the energy efficient, environment friendly direct evaporative air conditioning and forced heating system having low operating cost suitable for hot and dry regions and climates .The objective of this paper is to develop an advanced 360 degree rotating air cooler& heater which provides air cooling and heating in all directions. Simple 360 degree evaporative cooling is achieved by direct contact of water particles & a moving air stream. When a hot and dry air is allowed to pass through a wet cooling pad, the temperature of incoming air is reduced with an increase in specific humidity as some water from the pad is evaporated taking the latent heat of vaporization from the incoming air.360 degree heater, is forced convective heater that has an electric fan to speed up the air flow. In a convection heater, the heating element heats the air in contact with it by thermal conduction. Hot air is less dense than cool air, so it rises due to buoyancy, allowing more cool air to flow in to take its place. To achieve comfortable temperature either as heater or cooler.

Postharvest losses of fruits and vegetables are a serious problem during handling, transport and storage. In order to overcome that issues, synthetic preservation and food additives are added to prolong the shelf life of fruits and vegetables, but it causes some allergies. Alternative methods of bio preservatives using Aloe Vera edible coatings over fruits are used to improve their quality and shelf-life. It is composed mainly of polysaccharides and acts as a natural barrier to moisture and oxygen. Aloe Vera gel has the ability to prolong shelf life of the fruits and vegetables by reducing the rate of respiration and maintaining quality like color, flavor etc. Aloe Vera gel is being increasingly studied as edible coating in fruits, which would be an innovative and interesting means for commercial application and an alternative to the use of postharvest chemical treatments leading to the enhancement of shelf life of fruits. This review paper summarizes the different preservation techniques of plums.

Literature Review for Improved Mutual Coupling Techniques in UWB MIMO Patch Antenna

Pages: 13 - 15
This paper discussed literature review of different authors who tried different technique to improve the mutual coupling in UWB MIMO patch antenna. Ultra-wideband (UWB) systems have been received a growing interest due to the successful applications of high throughput, multimedia streaming, radar and biomedical imaging. Federal Communications Commission (FCC) has approved the use of the frequency range of 3.1–10.6 GHz without license for low power emitting systems. The UWB systems operate over a wide bandwidth with low spectral power level. The signal to noise ratio (SNR) is hence too low at the receiver. The throughputs of the systems have been also extremely increased thanks to the recent developed data coding techniques. However, it has been almost restricted, since the emitted signals are inherently subjected to interference and multipath fading in propagating environments. The transfer rate can be excessively increased and the fading effects can be reduced by utilizing multiple input multiple output (MIMO) concept because of introducing spatially multiplexing and diversity. Designing MIMO systems with multiple antenna elements for mobile terminals has been more difficult since the mobile terminals have been towards to be smaller, and thus MIMO antenna elements must be accommodated in these constricted terminals with the other electronic components. At the same time, the elements are inevitably exposed to high mutual coupling among them, because of operating closely each other. Mutual coupling must be minimized to isolate the channels electrically to provide an efficient MIMO system.

Pages: 16 - 20
A compact simple broadband circular V-shaped slot antenna microstrip antenna is proposed for circular polarization (CP). The Circular polarized patch consist Z type feed line on top of substrate and two right angle V shaped slotted cut on gnd plane which is shown in backside of substrate. The multi response is achieved by using stub element in feed line Using stub element the broad CP and impedance bandwidths overlap by the symmetrically etched right angled V-shaped closed slot along the center line and the Zshaped feedline placed in a proper position. The proposed wideband CP antenna exhibits a much wider impedance bandwidth (1.61-4.85 GHz) of about 135.5% (S11 < −10 dB). The broadband CP antenna offers good gain over the entire frequency band of operation for Wireless applications. The proposed antenna possesses a high gain of 5.4 dB with the overall size is 44mm*50*1.6mm2.Proposed CP Broadband antenna covering UTMS, PCS, 2G,3G, WLAN, LTE, and WiMAX band applications.
