L’Âge d’or (The Golden Age) was Luis Buñuel’s second film and was released in 1930. The patrons of this film were a French couple who got impressed by Buñuel’s first film: Un Chien Andalou (An Andalusian Dog) (Sánchez Vidal ‚ cited by Stone‚ 2013). The film has a critical reception‚ which censures the selfish of middle upper class. Corresponding‚ it is a surrealist film and focused upon inner and outer realities at the same time (Radall‚ 1976:4). I am going to analyze the sequence from the mid-way

The position of Ser- His- Asp (catalytic triad) was quite similar to the predicted residue position of 15‚ 192 and195 respectively‚ as described earlier in Fig 1b. Notably‚ In the Fig 5a‚ the orientation of the active side loop was significantly altered that could be an important factor to effect the observed difference in catalytic efficiency and Km between Cbes-AXE2 and AXE2.

chloride are measured by heating a weighed sample of potassium chlorate and determining the amount of residue (potassium chloride) remaining. The decrease in mass brought about by heating represents the amount of oxygen originally present in the sample. From the experiment we obtain the following three values: 1. Mass of original sample (KCIO3). 2. Mass lost when sample was heated (Oxygen). 3. Mass of residue (KCI). From these experimental values (and a table of atomic masses) we can calculate the following:
