column loads that require thicker foundation slab considering economy of the structure. Both beams cast monolithically with raft slab. Solid raft foundation The unified solid raft foundation is the most simple foundation form and its formwork assembling as well as its reinforcement implementation do not require hard labor. Solid raft foundation In the solid raft foundation‚ there is only one unified foundation slab. The foundation slabs are reinforced with two wire meshes‚ one placed at the

Throughout term two our class has been participating in the unit of tennis. We have researched the key components of fitness for a tennis player and have conducted a number of fitness tests to base ourselves upon. By evaluating myself on these tests‚ I have chosen to compete against Contender A of the 4 contenders. My decision in doing this not only lies upon where my strengths are where stronger then his weaknesses‚ but where i am weak he is not strong. A typical tennis player‚ apart from skill

Experiment 2 – Identification of Inorganic Solids Jesse Galina CHM 101 Lab Monday October 1‚ 2012 Unknown Solid – 2 Identifying my cation was rather easy because of the color of the powder when it was first given to me. It was pinkish/slight red when solid and when it was grounded up even further. This observation ruled out every cation except for some hydrated Co (II) salts. After being dissolved in water‚ the solution turned pink which agrees with the statement that the cation was Co

Students at NFV middle school are on a journey to figure out a mystery mixture. They have to search through 9 chemicals to figure out which one is it. Seems easy huh? Nope‚ they have to analyze the physical and chemical properties (a very important part in this)‚ the data‚ argue‚ and give important statements on what they think is in the mix. That’s when arguing comes in‚ not arguing on the person but the statement. I think it is citric acid and baking soda. Eighth graders have to find out what

Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed
