in a place where my interest is. My goal is to master the course material in this upcoming year. Although…

written materials that have offensive words in them or why there's specific written materials that can be found online but not at your local library? That’s because of banning and censoring. Banning is the act of excluding information from one place that can be accessible from another location, while censoring suppresses words or graphic images from viewers. There are times that some written materials should be banned but written materials should never be censored. Some written materials…

ability to last centuries unaltered. Some documents are created for the present alone such as to do list and letters while some documents are created to last for centuries and are written to survive the trials of time. In general, durable writing materials required excessive time and labor to produce. Written eye witness testimonies became more reliable and trusted than recited oral history. Through deciphering and translation, writings from all times and languages can be understood. The…

Innovating Building material Solar –thermal cladding (solar activated façade) The innovating building material I am going to write about is The Solar –thermal cladding . This type of cladding is the new type of cladding whereby solar panels are added to the cladding to form a more efficient and sustainable materials for all sorts of buildings. ( Eco building pulse, 2016) This is a new style where by the solar panels are hidden and are covered by materials such as wood , at this moment in time…

Task 2 Non-destructive testing is an analysis technique used to evaluate the properties of a material, component or system without causing damage. Advantages Safety Non-destructive tests are designed to maximize both tester and tested product safety. Most of the test are conducted under strict settings to ensure the safety of the testers, and all tested products remain completely undamaged. Reliability Non-destructive testing comes out with accurate results because of the variety of available…

led to harder material by creating linear defects known as dislocations. The specific type of dislocation that occurred in this lab was an edge dislocation where an extra plane of atoms was inserted into the crystal structure. If enough pressure is applied on the material, a permanent deformation stemming from dislocations can occur, known as plastic deformation. The hardening of materials through the use of deformation in a material stems from the atomic structure of a metallic material.…

Using Cedar Roofing Is your home’s aging roof finally in need of replacement? If so, you will be wondering what material you should replace it with. You are not limited to replacing the roof with the exact same material, since you’ll now have many options available to you. Here are a few things to know about using cedar roofing for your home. Lifespan It is likely that you want a material that will be durable, which is exactly what you get with cedar roofing. You can feel good about using…

Reduction Coefficient, is the average of the levels of absorptiveness in a material at four different frequencies; 250, 500, 1000, and 2000 Hz. If a material has an NRC of 0, it will reflect sound. If it has an NRC of 1, it is perfectly absorptive. These numbers can be converted into a percentage, therefore ranging from 0% to 100% in absorptiveness. (Noise Reduction Coefficients (NRC) Ratings for Common Building Materials & Products, n.d.) In order to soundproof a room, one must keep in mind…

students to be exposed to new material while effectively preparing them for possibly shocking or traumatic information, enabling them to excel in academics. In college classes, students are often exposed to new concepts and material they would not have encountered in high school. For some students, the graphic subjects contained in the material may be unnerving. When students encounter uncomfortable content without warning, they are often too focused on the shocking material to effectively…

is flat and tapered, and somewhat like a chisel. The materials that are made for the handle of a screwdriver are steel, wood, metal or plastic. In addition, the steel tips are generally plated with nickel or chromium.
