Mastering Research Skills: From Concept to Conclusion" is an educational guide designed to help students and professionals develop effective research abilities, from identifying a topic to presenting final findings. It covers each step of the research process, including selecting a research question, conducting a literature review, designing methodology, collecting and analyzing data, and writing a well-structured report or thesis. The book emphasizes critical thinking, proper citation, academic integrity, and clarity in communication, making it a valuable resource for anyone engaged in academic or professional research. - Understanding Research – Purpose, types (qualitative, quantitative, mixed-methods) - Choosing a Topic – Identifying a clear, focused research question - Literature Review – Finding and evaluating existing sources - Research Design – Planning methodology and tools (e.g., surveys, interviews) - Data Collection – Gathering relevant, reliable data - Data Analysis – Interpreting results using appropriate techniques - Writing the Report – Structuring introduction, body, conclusion, and references

Amylases are well known for applications ranging from starch and food processes industry to medical applications. The increased demand for these enzymes in various industries has led to an enormous interest in developing enzymes with better properties such as raw starch degrading amylases. It is suggested that banana peel and male inflorescence could employ as a promising substrate for the production of amylase by Aspergillus niger. Further, solid state fermentation is a better choice for amylase production. The addition of external growth medium is also found beneficial for increasing enzyme production. The present study was undertaken to isolate, identify and characterize the Aspergillus niger in the culture medium followed by amylase production and extraction. The banana parts used here as substrates are ripe fruit peel and male inflorescence from locally cultivated species Ethan (Nendran), Palayamkodan (Palayanthodan), Rasakadali (Njali Poovan) and Sundari. The result shows that amylase from sundari peel have the best activity followed by Ethan peel. Ethan flower bud shows the least activity among the eight substrates under study.

Banana is one of the most important food crops all over the world. There are around 365 varieties of bananas available throughout the world. Banana is a traditional medicine for diabetes, cancer, diarrhoea and also highly nutritional food crop. In this study, commonly used varieties of banana are taken for characterization by morphology and genotype which is based on International Plant Genetic Resources Institute and RAPD analysis. Five varieties were morphologically similar in parameters such as leaf habit, pseudo stem appearance and peel color. RAPD analysis proved that these varieties of banana are closely related which coincides with the morphological characterization. Also, this study is aimed at examining the anticancer activity of Musa acuminata variety of banana which is commonly consumed in southern part of India. Anticancer examination of the sample was performed for the hexane extract using DLA and MG-63 cell lines which showed a high degree of anticancer activity which was proved by the cytotoxic effect on the tumor cell lines. Phytochemicals present in the plant concentrate provoked cell apoptosis and smoother cell expansion to quickly partitioning malignancy cell lines. Among the five varieties analysed, Musa accuminata Colla variety shows increased level of anticancer activity in both cell lines. So it is anticipated that this variety can be used as medicine orally for cancer treatment.
