The following figure 1(a) shows a part of a reinforced concrete building in a school. The structure consists of precast concrete hollow slabs that rests on the 10.8m long two reinforced concrete beams. The beams are supported on reinforced concrete columns. It is given that, on the top surface of the hollow slab, there will be a concrete screed with 50 mm thickness (assume density of concrete screed is 25 kN/m). In addition, there will be tiles that weigh 0.05...

3 Casimir effect We will derive the Casinir effect in three dimen- sions, making use of the Euler-Maclaurin formula where θη _ 1 for n > 0,4,-1/2, and θη 0 for n <0. (You don't need to prove this formula.) Let us consider walls of length L. Let EL be the vacuum energy inside the box. We now insert a conducting plate at a distance RL parallel to one of the walls, dividing the volume into two. Denote ER and...

Recognize the following major structures and know how changing the structure will effect the activity (if we discuss any): Penicillins, Cephalosporins 1. What is the mechanism of action for penicillins and cephalosporins? Is it bactericidal or bacteriostatic? What are the side effects? 2. What is the common structural feature of all penicillins and which is the functional group that is modified? 3. What are the common problems associated with natural pencillins? 4. What does hypersensitivity have to do with chemical...

3 Casimir effect c. All vacuum energies considered so far are infinite. In reality, the metal walls are conduc tors only at finite frequencies, and thus do not impose boundary conditions at infinite frqu cies. (The cutoff is given roughly by the plasma frequencywp Thus, we need (and should) not consider infinite frequencies in our equations. To remove We will derive the Casimir effect in thee d sions, making use of the Euler-Maclaurin formula imen- them, we introduce a cutoff...
