1. Introduction: The goal of this lab was to demonstrate the microbiology technique of serial dilutions and how they can effectively be used in experiments. E. coli cells were exposed to UV light for various amounts of time in order to asses the effect on growth and thereby mutations since this cell was modified to not have photolyse no uvr genes for DNA repair and thus can only use the SOS response. Each group then diluted the cells accordingly based on their UV exposure time and counted the cells

are non-terminating and non-repeating. Rational and irrational numbers together constitute Real numbers and it is denoted by R. Equivalent rational numbers (or fractions) have same (equal) values when written in the simplest form. Terminating fractions are the fractions which leaves remainder 0 on division. Recurring fractions are the fractions which never leave a remainder 0 on division. There are infinitely many rational numbers between any two rational numbers. If Prime factors of the denominator

What really happens Before Sunrise and Before Sunset? By: David Pickett (209048489) Postmodern condition in cinema implies a deviation from the mean in terms of conventional narratives. Before Sunrise doesn’t end with both Jesse and Celine staying together in love. Sunrise ends on a cliffhanger leaving the audience caught in suspense with the desire to know if they both come back and meet six months later at the train station. Most of the conventional love stories end happily with the

Algebraic Fractions An algebraic fraction can always be expressed in different‚ yet equivalent forms. A fraction is expressed in its simplest form by cancelling any factors which are common to both the numerator and the denominator. Algebraic Fractions can be simplified by cancelling down. To do this‚ numerators and denominators must be fully factorised first. If there are fractions within the numerator/denominator‚ multiply by a common factor to get rid of these and create an equivalent fraction:

Individual solid particles are characterised by their size‚ shape‚ and density. 1.1 Particle shape The shape of an individual particle is expressed in terms of the sphericity F s‚ which is independent of particle size. The sphericity of a particle is the ratio of the surface-volume ratio of a sphere with equal volume as the particle and the surface-volume ratio of the particle. For a spherical particle of diameter D p‚ F s =1; for a non-spherical particle‚ the sphericity is defined as Dp:
