An advancement in Concrete and Pavement

Concrete is currently the second most used material in the world only second to water, with an esteemed 3 tones per person every year. Concrete being the main material used in architectural designs and infrastructure used for buildings, streets and bridges is responsible for 8% of the world's carbon emitted. As concrete has become a necessity in buildings it has become the mission of researchers at the University of Tokyo to develop a new chemical build up of concrete to make it more suitable for our environment. They have an idea of using calcium from concrete waste and then using carbon dioxide from either industrial exhaust or directly from the air to create a calcium carbonate concrete material. The  issue with concrete carbon emission has been a known problem for a long time now and even the concrete industry is searching for solutions to this problem. With this new concrete idea of using carbon dioxide and reusing concrete in landfills could offer a new path for the concrete industry and hopefully achieve the goal of making this new concrete carbon neutral and even negative. Along with a new concrete creation in the works there have also been improvements in creating a more flood resistant pavement. As we know Hurccain Harvey created a lake out of Houston, and there is no question that there could be improvements on its drainage for future floods. While there have been pavement designs made for improved flooding the main issue is clogging, as large pieces of dirt could easily blog the draining system. This new design uses microscopic porus in the pavement so that the water can be absorbed from the surface without taking in any dirt that may block the circulation. 

The issues that these innovations are working to fix are clever ways to bring change to problems that need it. I find that in terms of the new concrete build up it is important for the government to have an educated understanding about any and all concrete replacements as to influence companies to use these new forms of concrete to better our environment and cities. I feel that this absorbing pavement is a great way for cities with high flooding to be improved. Communities that live in high flood areas, such as here in Houston, would most likely be open to this change as it would bring great improvement to the city. Any citizen of city that is need of change should be open about their response, while it is usually the government that can control the change it is the people opinions and actions that can make a difference in change.

Cultural Anthropology blog

 India Riley Mr.Roddy IHSS September 2, 2021 Anthropology blog     My article was about wildfires. All across the Mediterranean fires are increasingly becoming larger, and more dangerous. This could be due to many different causes, the most likely is human inflicted. Because of climate change the chances of a fire have significantly increased. While farming is practical and beneficial for food, most farming strategies have become more harmful than good for our environment. The chemical pesticides and fertilizers are extremely flammable, with just one spark the entire field could burst into flame within minutes. When dedicating a large amount of land to farmland or cattle range, its safe to assume that at some point that will be engulfed in a fire. Rarely a field could emerge to flames even if a human hasn't touched it, because plants release so much oxygen, too much of any sort of plant could combust to flames during drought seasons or lightning storms significantly...

Prisoner of The Infidels

  Niko Cantu Mr. Rodey IHSS 21 October 2021 Prisoner of The Infidels 1）Osman’s writing is far more modern than other writings from his time. It has a very direct and straightforward structure and its translation to English is paractly identical to modern English writing. An example of this direct writing was when Osman said “From this, I understood God's will,namly, that my master had no intention of ever granting me freedom”. This sentence for one use I as he refers to himself in the first person, which was not very common during that time.   2) Osman is clearly very connected to his Muslim religon and repedidly mentions Allah throughou the story. A clear example of this use is when he says “I have no money, and no one is going to help me because of Allah''. This is a clear example of how SOman instinctively believes that Allah may not have an effect on his current situation, he thinks of Allah as a part of his daily life.  3) A discussion that Osman had to make was...

IHSS reading Prisoner of the Infidels Ira Williams

  Ira Williams Mr.Roddy October 27, 2021 IHSS IHSS reading Prisoner of the Infidels Pick a section to note the style of his writing.  How would you characterize it? The writing was very descriptive and rough at the same time, it made you see and picture the things he was going through and realize how bad it was. It was very humbling to read how he was beaten and imprisoned in a cell with his hand and feet shackled, on his stomach too. What role does his religion play in his thinking?  Give an example. He was very risky in what he did because he had is divine wisdom and foresight to guide him, as well as Allah to fall back on . one instance of this is when he “saw” people surrounding the city and so he slid along a frozen lake to another town, where he hid in a barrel. What is a decision that he had to make?  Do you think it was a good one? Why or why not? When he left his old master, I think that he should have stayed, he was treated pretty well, even was given some ...
