Personally, I am a firm believer of communication being an important method of connecting between two parties. I always have great respect for people who are able connect well with others through the way they communicate as it is a trait that I am greatly lacking in. Since my younger days, I have always been terrible at conveying my thoughts, and this tends to lead to cases where people misinterpret what I am trying to convey. Truthfully speaking, I felt nervous and uncertain when I noticed that effective communications was part of my module this trimester. However, a part of me hoped that through this module, I am able to better communicate with my peers or the audience. Thankfully, as the module progress, I learnt to convey myself better through the impromptu minor presentations and team work assigned by Professor Brad. These experiences truly helped me structure my words and thoughts to convey efficiently. There were many minor presentations throughout the module, and as much as I...

In the article, “The Self-healing Concrete That Can Fix Its Own Cracks”, Spinks (2015) described an innovation that Jonkers invented, which was embedding self-activating bacteria into concrete to make it self-healing. He stated that the bacteria can exist for up to 200 years as long as particles exist for it to feed on, and also mentioned that the bacteria would start producing limestone to repair the cracks when water starts seeping into the cracks. He also noted that the self-healing concrete was unable to repair large cracks, and only capable of repairing cracks up to 0.8mm wide. According to Jonkers, a cubic meter of concrete costs €70, while the self-healing concrete costs €100. Nonetheless, Jonkers remarked that some countries with coastal communities or tropical regions with extreme rainfall are seeing the cost-benefit analysis of using the self-healing concrete. It was concluded by Jonkers that these tests were done in developing countries where they see profits in the future....
