Asymmetric curcumin analogues are anticancer compounds that are synthesized from Cullilawan Oil with several stages of the process include: isolation safrole from Cullilawan Oil, safrole isomerization, oxidation, synthesis intermediate product and synthesis asymmetric curcumin analogues. The final stage of the process is the aldol condensation reactions using microwaves method that are affected by the processing time, power and concentration. The purpose of this study is the optimization of synthesis process conditions asymmetric curcumin analogues using response surface methodology and to determine the best model to obtain optimum process conditions. Design of experiments using a box-behnken design with 3 variables (power, time and concentration) and responses used is the yield that is associated with purity............
Author Keywords:- RSM, asymmetric curcumin analogues, microwaves method

Index: 10.183x/B61110711 aned
The management of biomedical waste is subject of important concern for public and also infection control specialist. As everyone knows that several types of health care activities produces various types of hazardous and contagious materials. Although we all know that in some manner it is harmful to public health, yet very recently people and government became aware about its proper management and disposal in India. Unscientific disposal of biomedical waste may cause transmission of communicable disease spreading through air, water and direct human contact by means of blood and infectious body fluids. These can be responsible for spread of hepatitis B, C and E and even AIDS within a community. Hence, proper handling, treatment and disposal of biomedical waste are important parts of healthcare infection control program. Appropriate management of biomedical waste is thus an important part of environmental health protection and it should become an integral feature of health care services. This review paper discuss about how to treat and dispose the biomedical waste.
Author Keywords:- Bio-medical waste, solid waste management, handling of bio medical waste, treatment of biomedical waste.

Cooling fins in IC engines remove excess heat from it to protect its components from thermal damages. These fins work on the principle of convection heat transfer. The cooling efficiency of the engine fins can be improvised by changing geometry, thermal conductivity and the material of the cooling fins. Computational fluid dynamics is the technique used to determine thermal stresses and temperature distribution through the fins. CFD analysis gives accurate and realistic results in comparison with physical analysis processes. This project is based on designing more efficient cooling fins for a 150 cc (Honda Unicorn) bike engine by improvising the design and the material of the fin. Where the modelling of the fin is performed on Creo modelling software and the CFD analysis is performed on ANSYS 15.0 Workbench software.
Author Keywords:- Creo 3.0, ANSYS 15.0, CFD Analysis, Steady State, Transient State Heat Transfer.
