Yeast Mutations due to Ultra-Violet Light Exposure Summary: Mutations have played one of the most important roles throughout life on Earth. Without genetic mutations there would not be the diversity of living species that we see today. Understanding how mutations work and how they are created is an important step in controlling and isolating genes for experimentation. In this experiment we tested the effects of Ultra-Violet light on growing single-celled yeast. We did this by first creating serial

seeding during ultrasound-enhanced deracemization. We theorized that by introducing larger seed crystals to the system after the establishment of the monodispersed sized crystals (~2 hours)‚ we would broaden the crystal size distribution and thus allow the deracemization process to resume. To test this idea we performed seeded experiments using ultrasound‚ in which we introduced 2.5 g of large seed crystals (~200 µm‚ e_0= 40%) after sampling of the 2nd hour. Obviously‚ the addition of extra mass of

quite solid‚ neither is it a liquid. Liquid crystals are another important intermediate phase which exhibits features from both the solid and the fluid state. Liquid crystals have the ordering properties of solids but they flow like liquids. Liquid crystalline materials have been observed for over a century but were not recognized as such until 1880s. In 1888‚ Friedrich Reinitzer (picture) is credited for the first systematic description of the liquid crystal phase and reported his observations when

PIEZOELECTRICITY AND APPLICATIONS Piezoelectricity is the ability of some materials such as crystals and certain ceramics‚ to generate an electric potential in response to applied mechanical stress or heat. If the piezo crystals are not short-circuited‚ the applied charge induces a voltage across the material. The word Piezo is derived from the Greek “Piezein”‚ which means to squeeze or press. The piezo material exhibits both “Direct piezo electric effect” as well as ‘Converse piezo electric
