EXPERIMENTAL STUDY ON ALTERATION OF NATURAL SAND BY CRUSHED PEBBLE SAND (REPLACEMENT OF FINE AGGREGATE), ANBARASAN.S, VASUNDARA.S, VENGATESH.K, YOKHESH.C

In recent years fine aggregate plays a main role in the preparation of both concrete and mortar in construction work. Generally, we are widely using quarry sand (Manufactured sand) has as an alternative for natural sand. In this project we used the crushed pebble sand which is produced by crushing the pebbles is one of the alternative materials. The purpose of this study is to investigate the possibility of using crushed pebbles as fine aggregate fully with different grades of concrete composite. The suitability of crushed pebbles waste as a fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete. Basic mix was chosen for natural sand to achieve M25 grade concrete. The equivalent mixes were obtained by replacing natural sand by crushed pebbles partially and fully. The test results indicate the crushed pebbles waste cannot be used effectively to fully replace natural sand in concrete. In the experimental study of strength characteristics of concrete using crushed pebbles as fine aggregate it is found that there is no increase in compressive strength, flexural strength and tensile strength of concrete when compared with natural sand.


TRAILER BRAKING SYSTEM, N.DHAVANEESWARAN

The trailer is a large load carrying device installed at the back of a tractor. It is used for carrying heavy loads in agricultural purposes and also for carrying goods. It is also used for towing a vehicle. Whenever brakes are applied to the trailer vehicle, it is applied only to the vehicle at the front. The trailer stops only when the vehicle stops. This causes the inertia force of the trailer to act on the vehicle. This leads to severe accidents in case of sudden or panic braking. It causes damage not only to the vehicles, but also it leads to death in case of severe accidents. Our project aims to reduce this incident in the case of trailers by installing braking system separately for the trailers. A hydraulically actuated disc brake system is used in this project because of its advantages over the other system. This system causes the application of brakes in the trailer wheels when the brake is applied at the front. The brake pedal is modified for this system. The master cylinder is attached with the pedal and the output is given to the calipers at the trailer wheels. In between a check valve is connected with the brake hoses which allows for the easy engagement and disengagement of the trailer with the brakes. The developed tractor-trailer braking aids in reduction in the stopping distance, decreases the effort required by the driver, even wear and tear of the brake pad, improvement in stability and reduces the number of accidents of the vehicle. Jack knifing i.e., formation of acute angles, is caused to the vehicle when sudden braking is applied to the vehicle moving on slippery roads. A jack knife crash has the potential to cause very serious injuries and even it is a fatal one for many people. Jack knifing of the vehicle is prevented when the vehicle towing a trailer is about to skid when the trailer braking is adopted. It means that the vehicle and the trailer are in the form of an acute angle. This trailer braking is very much essential to control such jack knifing when the vehicle skids. In conclusion, the developed trailer braking system improves the safety of the tractor vehicle during operation with trailer.

BIOSORPTION OF LEAD FROM WASTE WATER USING RICE HUSK, DRISYA G. CHANDRAN, SINDHU NANGARTHODY

Excessive release of heavy metals into environment due to industrialization and urbanization has posed a great problem to the world. A little exposure of these metal ions even at low concentration can give bad effect to human body and environment itself. Heavy metal ions do not degrade, so the removal of heavy metals from water is to be considered seriously. Adsorption technique is adopted for decontamination of metal ions. The purpose of this study is to investigate the effectiveness of rice husks as adsorbent for the removal of lead ions. Rice husk is preferred to any other materials because of its abundant availability in India and also its low cost. The lead ions removal from aqueous solution was studied using batch method. The adsorption process of metal ions from waste water is influenced by various physical and chemical parameters like pH, contact time, adsorbent dosage etc. Two types of adsorbents are used in this study, one is prepared by grounding the rice husk into small size and another one is obtained by burning the clean rice husk in muffle furnace and treating it with hydrochloric acid. The waste water is prepared synthetically in the laboratory and treated against two adsorbents. Characterization of both the samples was done by using FTIR. Among process parameters, pH has a significant role in controlling the adsorption of lead ions. It was found that the adsorption capacity of grounded rice husk increases with increasing pH of the solution. Maximum adsorption occurs at a pH between 4 and 6, adsorption capacity decreases at pH 7. Removal efficiency of grounded and carbonized rice husks(GRH &CRH)also increases with increase in adsorbent dosage and contact time. While comparing the removal efficiency of both grounded and carbonized rice husks, the former one has more efficiency. Hence it can be concluded that, grounded rice husk can be used as an efficient adsorbent. The implementation of this study will provide a better adsorbent for waste water treatment.


ISOLATION OF CASSAVA LINAMARIN AS A MINIMAL IMMUNO-SUPPRESSIVE DRUG AGAINST CANCER, STEPHY JOSE, BEULA C

Cancer is a disease caused by some physical, chemical or biological factors that leads to unregulated proliferation of cells resulting in the formation of malignant lesions. Although there are a number of treatment methods available against cancer, majority of them have side-effects. The use of natural remedies for developing a chemo-therapeutic drug that is minimally immunosuppressive but selectively kills the cancerous cells is the major objective of the research. Cassava (Manihot esculenta Crantz) has been proven to be a natural remedy against cancer due to the cyanogenic compound linamarin present in it. The isolation of cassava linamarin by acid hydrolysis followed by adsorption on activated carbon can produce highly purified end- product that can be used as an anti-cancer agent. The acid hydrolysis was carried out using 0.1M H2SO4 and the crude cassava extract (CCE) obtained was analyzed for functional groups using FTIR spectroscopy. The hydrolyzing solution was prepared using 0.1M acetate buffer and the enzyme obtained was purified using membrane filtration (0.45μm). For quantification of the linamarin present in CCE, UV-Vis spectroscopy was conducted to obtain the calibration curve (absorbance versus concentration curve) from which the concentration of linamarin present in the sample measured in hydrogen cyanide equivalent terms was found to be 0.97μg for 0.1ml of CCE used that was hydrolyzed using 11ml of hydrolyzing solution containing linamarase. The UV-Vis spectroscopic studies revealed that the optimum time required for the purification of linamarin using activated carbon adsorption was 35 minutes. Thus, an approach for the isolation and purification of linamarin by combining acid hydrolysis and activated carbon adsorption technique was proposed.

STATCOM TECHNOLOGY: A SOLUTION FOR LOW VOLTAGE RIDE THROUGH REQUIREMENT IN WIND ENERGY CONVERSION SYSTEMS, KAVITHA SURESH, K N CHANDRA BOSE, MANJU A S

The operation and control of the power systems are greatly affected by the increased penetration of wind farms in the electric grid. Therefore, wind farms are expected to stay connected even during short term faults. Whenever there is a fault in the grid, the voltage at the point of common coupling gets disturbed. As a result, the grid connected Wind Electric Generators (WEG) get disconnected from the grid causing a sudden loss of generation in the power system. If the fault isn’t cleared within a short duration, the power system will face a huge generation load mismatch which may even lead to blackouts. Therefore, the wind energy conversion system needs to satisfy the most important grid code requirement known as the Low Voltage Ride Through (LVRT) to prevent unintentional islanding. In this work, Static Synchronous Compensator (STATCOM) is used to provide the LVRT capability. STATCOM is synchronized with the grid using Synchronously Rotating Reference Frame Phase Locked Loop (SRF-PLL) based grid synchronization algorithm. In order to demonstrate the LVRT capability, simulations have been performed in MATLAB/Simulink environment under normal and faulty conditions with and without STATCOM. The resiliency of SRF-PLL is also highlighted through MATLAB simulation under different grid conditions.
