This paper explores the application of GeoGebra software to assist teachers and students in lessons on fixed points of families of lines and circles, a relatively complex topic in secondary school geometry that requires logical reasoning and advanced proof skills. GeoGebra, as a visual modeling tool, enables the discovery and proof of fixed points in problems involving families of lines and circles.

A fragment-based approach has been applied to derive 2-(7-hydroxy-2-oxo-2H-chromen-4- yl)acetic acid 1 into 4 new coumarin derivatives 2a-d through amide bonds. The compounds were screened for their anticancer activity using MTT assay on MCF-7 and HepG2 cell lines.

Hybrid technology in many crops has contributed 20-30 per cent increase in the production and exploitation of heterosis through the development of F1 hybrids which has been recently deployed in rice with yield advantage of 20-25 per cent over best pure lines. The main aim of any plant breeding programme is to develop special high yielding hybrids and success of any plant breeding programme depends on the choice of appropriate genotypes as parents in the hybridization programme.

A communication link with retransmission is proposed for assessing the reliability of transmitted messages over composite (radio wired) communication lines. This solves the problem of the feasibility of using a communication repeater.

The growing concern for safety and infrastructural proliferations in the densely populated urban and suburban areas as well as the quest to preserve the aesthetic values in many modern localities have necessitated the need for underground installations.
