Write a 3 pages paper on reflection on plasticized. The pollutants become part of organs of the fish which are then consumed by humans.Chelsea conducted a lab test where she confirmed that plastics do have disruptive effects on the bodies of fish where it can not only affect their organs it also effects their endocrine system, thereby halting their reproductive systems. As per her research work, she says plastics don’t biodegrade they photo-degrade, that is, the sun breaks them down into smaller and smaller pieces and this happens only out at sea. A perception is that plastic will degrade automatically just like all other organic material that is used for packaging, while plastic never biodegrades. Most of the world which is a contributor to production and consumption of plastic is unaware that plastic will not finish off on its own, it will require optimum conditions created by human beings to become unavailable. Dr Marcus explains that his research has only covered a teaspoon of plastic on the ocean floor since the trawl was trawling only a small surface area. The ocean covers 2/3rd of the earth and sieving through a small area also brought out results. The results are relevant in terms of the micro-organisms that inhabit the surface and the fishes that feed on the surface. These fishes are eventually foddered for bigger fishes which become human food. The plastic and its components affect humans through the food chain. In effect, we create our own problem. Most of the team agree that damage control is the solution rather than cleaning the sea.

Write a 10 page essay on Frost resistance of concrete containing brick aggregate.

This amazing ability also allowed him to predict, characterize and exploit the chemical and physical qualities of minerals, metals and other elements found in nature. It is this specific knowledge that makes it possible to develop new applications in the industries such as construction, shipbuilding, manufacturing, food production, etc. Early structures built by early civilizations of Egypt, China, India and other nations are still in existence today, although most of them are in ruins already. Man will always build new structures as habitat and places to work in, sometimes building skyscrapers to maximize the use of limited land. However, a growing realization that Earth’s resources are not infinite has lead to the Green Movement in the construction industry these days. A big component of today’s modern structures is concrete which makes up more than 60% of the total volume in construction materials. This paper discusses the exciting possibilities of using concrete with brick aggregates in them to improve their frost resistance and make them long-lasting. This paper examines the use of brick aggregates instead of the other usual aggregates in cement. Some studies showed brick aggregates concrete to have better qualities (Singh 27). I. Aim of the Project It is the aspiration of every architect and engineer to build structures which can last for long periods of time. The idea is to build for posterity if possible and this can be done with the right types of construction materials. Concrete has always been a favourite material due to its availability, strength and ease of use. The word concrete comes from the Latin concretus which means compact or condensed. this makes concrete desirable as a material of choice. In concrete, builders have found the ideal material to construct grand buildings of all shapes and sizes. Concrete is a composite construction material derived by mixing cement with fly ash, slags, aggregates (made up of gravel, crushed rocks, limestone, granite and a little bit of sand) water and several chemical admixtures. Concrete solidifies into place after mixing it with water in a process known as hydration. The water reacts chemically with the cement to form and bond all its other components together into a hard rock-like material. Concrete is the most widely-used man-made construction material in the world today. A lot of factors determine whether the concrete will stand the test of time. Moreover, engineering structural designs need to take into consideration the actual load weights imposed on the concrete. A concrete structure is exposed to various elements of nature such as wind, rain, earthquakes, fires, moisture and snow, to name just a few. In other words, the durability of a structure is to a large extent determined by its exposure to the elements. An important consideration that allows a concrete mixture to withstand the extreme elements of nature is the design and composition of the aggregates mixture forming the concrete. It is in this regard that I am examining how brick aggregates can improve the frost resistance of the concrete. A re-examination of its desired frost-resistant qualities is vital because it will improve concrete structures by making them more durable. It will help in minimising use of scarce construction materials by reducing a need to build new structures to replace old ones. The problem of

Each Written entries(WR) are one page or 250-300 words minimum

1. things beautiful and things disturbing, an essay—more than a list

use narrative form that develops your thoughts on each of the following subjects—about 250 words total:

a. Describe 3 things you find beauty in.

b. Describe three things you find disturbing.

c.  Describe your first experience with art (any form that made  an impact on you).

2. The Artist and Spirit/response to samsara and assigned readings 

a.  Your response to the film. Describe what “spirit” means to you.

b.  Describe your feelings/opinion regarding the relationship between art and spirit.

Think about possible links between the ideas in “How to Look at Sand” and ideas in SAMSARA; where can you find resonances between the essay and the film?

3. scavenger hunt handout 

a.  Briefly describe the exhibition overall. For instance, discuss the different sorts of artwork are in the show; what may connect them to each other; and the overall mood or atmosphere in the gallery created by the show.

b.  Choose one specific art work: Give a brief interpretive analysis such as what you think may be the thematic concern or message you take away.

c.What do you appreciate most about this exhibition overall?

4. The Artist and Community 

Define the term community from both a local and global perspective.

a. Describe what you think should be the role of the artist in their community.

b.  What would be an ideal project that an artist could create within a community of your choice? Why?

5. as it is in heavenvisual diagram 

Diagram or otherwise trace the journey of discovery, healing and connection in AS IT IS IN HEAVEN: how does the artist (Daniel) impact this community? How does the community impact the artist?

A certain drug is eliminated from the body through urine.Suppose that for a dose of 10 milligrams,the amount A(t) remaining in the body t hours is given by A(t) = 10(0.8) t milligrams and that in order for the drug to be effective, at least 2 milligrams must be in the body

part a. Determine when (in terms of hours from administration ) 2 milligrams remains in the body. report answer with appropriate units rounded to the nearest hundredth of an hour.

Part b. What is the half -life of the drug ? report answer with appropriate units rounded to the nearest hundredth of an hour.

Part c. draw the graph of y= A(t) for T less than or equal to 0. Be sure to label the following : both axes with appropriate units, the coordinates from part A, and B and the
