Center was a global icon of The United States of America. The tallest of the buildings was over 1,300 feet high (10). With such large buildings, the materials used in construction needed to meet certain standards just to successfully stand erect. The design intent has the biggest factor for the material selection. In the World Trade Centers, the materials were supposed to meet certain properties and requirements. The analysis of whether or not the World Trade Center buildings were built to requirements

styles/designs you can use to create your bridge. Gather your supplies. Getting the correct materials for your bridge is crucial. Any of the materials listed above, in the introduction, can be purchased near your local dollar store. Reminder: The kind of popsicle sticks you buy, will determine the vision of your bridge. Begin creating. After you have planned out how you want your bridge to look, and gathered the materials needed, you can finally begin creating your bridge. Begin by choosing an empty workplace

Lintel is that all structural openings that have been development from the basic idea of post and lintel. The lintel must hold a majority of the weight that rests on it, as well as, its own load without serious structural damage occurring. The type of material used is another important factor when deciding how large the structure will be. For example,

INTRODUCTION Global warming has become a central problem in the scientific community, while viewed as more of a severe problem by some people and policy makers than other, the consensus in the scientific community is that global warming is a very real phenomenon. Although the global warming is still debated as far as how fast and severe the problem is, scientific data has shown that the average global temperature has increased by 0.4 to 0.8 Celsius during the last 100 years (http://www.livescience

Situation Analysis The global packaging industry has seen many shifts in the last few decades. Technological advancements and changing consumer attitude have led to a move from the traditional packaging materials like wood, glass, and metal to economical, sustainable ones like PET, Tetra Pak, and other flexible packaging options. Marketers, retailers, and consumers prefer flexible packaging options over glass as they provide protection against hazards like moisture, heat, and chemical reactions,

How are the special properties achieved in glass Ethan Francke Introduction Glass is a vey common material used in everyday life and can be seen nearly everywhere you look. It can be found in; houses, class rooms, smart phones, glasses, microscopes, light bulbs etc. Even though it’s found nearly everywhere glass is used for various objectives and purposes.

attach onto the scaffolds. To obtain a scaffold with suitable mechanical and viscoelastic properties (Young’s modulus 0.35± .11 MPa, Tensile stiffness 8.59±3.5 MPa, Equil. Modulus 13.6±1.5 MPa), it is very important to choose the proper polymeric material and fabrication technique10, 29, 40, 45. To recreate the submicron and nano-ECM-like architecture of native trachea tissue, electrospun collagen fibers will be coated around the scaffold21,24. Collagen fibers will be embedded with bioactive molecules

According journalist Eric Goldschein, the United States drank 9 billion gallons of water in 2008 (Business Insider). Therefore, in order to prevent access waste and build up of plastic from the water bottles, many different varieties of reusable water bottles on the market today advertise the message of an eco-friendly product. This message, however, can be easily adulterated and twisted in the manufacturer’s favor for simply business purposes, thus promoting bottles that have only the perk of
