The structure of imide is as shown. Polyimides have been in mass production since 1955. Typical monomers include pyromellitic dianhydride and 4‚4 ’-oxydianiline. Polyimides are a very interesting group of incredibly strong and astoundingly

Introduction Good Morning Everyone. My name is and this is ‚ and . We will be presenting to you on how Light affects gene expression with focus on Maize leaves. This is an unrelated but neat photo of gem corn which is produced as a result of selective breeding. Anyways‚ most plants require light in order to grow and conduct photosynthesis. Plants that have been previously grown in the dark are incapable of photosynthesis since they lack chlorophyll and many polypeptides needed for light harvesting

This case presents some of the basic concepts of aggregate plan-ning by the transportation method. The case involves solving arather complex set of transportation problems. Four different con-figurations of operating plants have to be tested. The solutions‚ al-though requiring relatively few iterations to optimality‚ involvedegeneracy if solved manually. The costs are The lowest weekly total cost‚ operating plants 1 and 3 with 2closed‚ is $217‚430. This is $3‚300 per week ($171‚600 per year)or

1 Angle Modulation Angle modulation is the process in which the instantaneous angle of the carrier signal is changed according to the instantaneous amplitude of modulating or message signal. Carrier Signal‚ The instantane ous frequency is f i ( t ) = lim f ∆ t ( t ) ∆t → 0 1 d θ i (t ) 2π dt For an unmodulate d carrier‚ θ i ( t ) is = θ i ( t ) = 2π f c t + φ c ‚ where φ c is constant There are two ways of varying the angle of the carrier: By varying the frequency‚ ωc – Frequency
