President Roosevelt then set up a program to study uranium and the possibility of an atomic bomb. This started the series of events leading to the atomic bomb.

1. INTRODUCTION Here stated is the introduction for penicillin notatum which makes clear the reason for selecting this microorganism for this term paper .Species of Penicillium are ubiquitous saprobes‚ whose numerous conidia are easily distributed through the atmosphere and are common in soils. In soil analyses‚ using dilution plate techniques‚ Penicillium species are detected with high frequency (Domsch et al.‚ 1993). However‚ very little is known of interactions between Penicillium species and

1981-82. Average productivity increased to 2.3 tons per hectare (2.8 tons on irrigated farms) by 1983. By the late 1970s‚ the country had changed from a net importer to a net exporter of rice‚ albeit on a small scale. In the 1980s‚ however‚ rice production encountered problems. Average annual growth for 1980-85 declined to a mere 0.9 percent‚ as contrasted with 4.6 percent for the preceding fifteen years. Growth of value added in the rice industry also fell in the 1980s.

1. Define production. What are the factors of production? Define production: Production means the creation of Utility. Through production inputs are converted into output which can satisfy or meet wants or demands. So production is a process of transforming inputs into useable outputs. Utilities are created in three forms such as (i) Changing the form (ii) changing time and (iii) changing place. Example: Wood in a forest generally has no utility to a consumer but cutting the wood‚ changing

According to Sloman‚ (2004)‚ production is the transformation of inputs into outputs by firms in order to earn profit. Production can be divided into two types‚ that is short-run production and long-run production. Production in the short-run is the production period of time over which at least one factor is fixed as production in the long-run is the production period of time long enough for all factors to be varied. As mentioned by Sloman‚ (2004)‚ production in the short-run is subject to diminishing

The raw material is isopropanol. The isopropanol (lPA) feed is a near azeotropic mixture with water at BB wt yo IPA at 25"C and I atm. The feed is heated‚ vaporized‚ and superheated in a heat exchanger (E-401)‚ and it is then sent to the reactor (R-401) in which acetone is formed. The reaction that occlrrs is shown
