Development of College of Industrial Technology FM Broadcast Trainer

An FM Broadcast Trainer was developed to expose the students to the basic equipment needed in radio broadcasting. The cost of Portable FM Broadcast Trainer is much lower than the cost of the traditional commercial equipment because of the materials used. The FM Broadcast Trainer is laboratory equipment that can be used by schools offering academic programs in Industrial Courses specifically Electronics Communication courses. At present there is no portable FM broadcast station available in the local market. Some schools are reluctant to by new FM station equipment since these are quite costly. To resolve this problem, the researchers deemed it necessary to design and develop a portable FM Broadcast Trainer that is simple and affordable to fulfil the basic curricular requirements for offering courses in Electronics Communication Technicians. This is a requirement for our graduates to qualify to take the Radio Telephone Operator examination given by the National Telecommunication Commission the telecommunication body in the Philippines counterpart of Federal Communication Commission in the US. Aside from this, the station will be a venue for Mass Communications students and a vehicle for channelling important announcement from the School.

Raman Spectroscopic Studies of Various Aspects of Human Body Fluids

Raman spectroscopy proved itself a non-destructive technique which is being used extensively for the characterization of biomedical media for disease diagnosis. It is based on the inelastic scattering of light. It provides the information about the vibrational modes of a molecule. A Raman spectrum of a biological media contains the molecular fingerprints which are the intrinsic characteristics of molecules. This information can be utilized to train various statistical models that as a result become a powerful tool for the characterization, diagnosis and discrimination in a variety of ways. In this thesis, the outcomes of three studies based on the Raman spectra of body fluids have been presented. First of all, a study was conducted to choose an optimal substrate to be used for acquisition of Raman spectra of body fluids. Aluminum was selected as the most suitable substrate for recording Raman spectra of human blood and sera samples. In first study, blood samples of healthy and breast cancer (BRC) female subjects were used to analyse the molecular variations caused by BRC. Partial least squares (PLS) regression based model was developed, which highlighted the bio-molecular variations found between both groups. Among these molecules lycopene, phosphatidylserine, qunoid ring, calcium oxalate and calcium hydroxyapatite were found positively correlated while tryptophan, proline, valine, glycogen and tyrosine were negatively correlated with BRC. In second study, human blood sera samples were analysed for the molecular variations due the presence of antigen at an early stage of dengue virus (DENV) infection. It was found that level of cytokines and DNA rises, while the level of proteins with alpha and beta conformations along with lectins lowers in the sera due to DENV infection at an early stage. In third study, human blood sera samples were analysed for the screening of hepatitis C infection. Hepatitis C infected sera were tested for the presence of antibodies by ELISA. Analysis of regression coefficients revealed that trehalose, chitin, ammonia and cytokines are positively correlated with the hepatitis C while lipids, beta structures of proteins and carbohydrate binding proteins like MBL are negatively correlated with hepatitis C.
