Garcia BSBA MM 3-1 _________________________________________ March 26, 2013 I. Introduction Colors play an important role in our lives. It gives meaning to everything we see. As Human our color vision influences everything from our art and poetry to the colors we paint our homes and the clothing we choose to buy. Colors distinguish a thing from the other. Colors determine our emotions. Pablo Picasso once quoted, “Colors like features follow the changes of the emotions”. Do you feel happy in a yellow room? Does the color blue make you feel calm and relaxed? Artist and interior designers have already proven how color can dramatically affect moods, feelings and emotions. Color is a powerful tool when it comes to communication and can be used to signal action, influence mood and cause physiological reactions. How color affects the effectiveness of the business? Marketing is a science of satisfying human wants and needs. When this filed acquires the principles of color psychology, it would...

Master of Science Thesis Examiners: Professor Matti Karp Professor Raghida Lepistö Examiner and topic approved in The Science and Bioengineering Department Council meeting on 7.11.2012 Abstract TAMPERE UNIVERSITY OF TECHNOLOGY Master‟s Degree Programme in Science and Bioengineering Vasilenko Maria: Feasibility of using biosensors for heavy metal detection in complex matrices such as bio-slurries. Seminar paper, 97 pages November 2012 Major: Biotechnology Examiners: Matti Karp, Raghida Lepisto Keywords: environmental pollution, heavy metals, biosensors, slurries The quality of bioslurries that are used in industrial production and agriculture need to be watched very closely to avoid spreading of contaminants on area and poisoning of humans and animals. Because heavy metals are very stable and toxic in many chemical compositions, their amount should be estimated very thoroughly. A new approach that involved biosensors was tested in this study. Because the slurries are complex non-unified matrices which composed of two phases – solid and liquid, the cell behavior can varies a lot from the one that explained in water and so the estimation of ion concentration can be not reliable. It was shown that the cell actually behave different in the slurries. Normally the dissolved compounds suppress the biosensor activity and, in the same time, the ions in the...

...1. INTRODUCTION 1.1 Introduction to Nestle Nestlé was founded in 1867 on the shores of Lake Geneva in Vevey, Switzerland and its first product was “Farine Lactée Nestlé”, an infant cereal specially formulated by Henri Nestlé to provide and improve infant nutrition. From its first historic merger with the Anglo-Swiss Condensed Milk Company in 1905, Nestlé has grown to become the world’s largest and most diversified food Company, and is about twice the size of its nearest competitor in the food and beverages sector. Nestlé’s activities contribute to and nurture the sustainable economic development of people, communities and nations. Above all, Nestlé is dedicated to bringing the joy of ‘Good Food, Good Life’ to people throughout their lives, throughout the world. 1.2 History Of Nestle * The Nestlé Company was Henri Nestlé's search for a healthy, economical alternative to breastfeeding for mothers who could not feed their infants at the breast. * The Company formed by the 1905 merger was called the Nestlé and Anglo- Swiss Milk Company. The close of World War II marked the beginning of the most dynamic phase of Nestlé's history. Throughout this period, Nestlé's growth was based on its policy of diversifying within the food sector to meet the needs of consumers. * In 1947, Nestlé merged with Alimentana S.A., the manufacturer of Maggi seasonings and soups, becoming Nestlé Alimentana Company. After the agreement with L’Oreal in 1974, Nestlé's overall position...

...1/ ENERGY BANDS IN SOLIDS In this chapter we begin with a review of the basic atomic properties of matter leading to discrete electronic energy levels in atoms. We find that these energy levels are spread into energy bands in a crystal. This band structure allows us to distinguish between an insulator, a semiconductor, and a metal. 1-1 CHARGED PARTICLES The charge, or quantity, of negative electricity and the mass of the electron have been found to be 1.60 X 10- 19 C (coulomb) and 9.11 X 10- 31 kg, respectively. The values of many important physical constants are given in Appendix A, and a list of conversion factors and prefixes is given in Appendix B. Some idea of the number of electrons per second that represents current of the usual order of magnitude is readily possible. F'or example, since the charge per electron is 1.60 X 10- 19 C, the number of electrons per coulomb is the reciprocal of this nutnber, or approximately, 6 X 10 18 Further, since a current of 1 A (ampere) is the flow of 1 Cis, then a current of only 1 pA (1 picoampere, or 10- 12 A) represents the motion of approximately 6 million electrons per second. Yet a current of 1 pA is so small that considerable difficulty is experienced in attempting to measure it. The charge of a positive ion is an integral multiple of the charge of the electron, although it is of opposite sign. For the case of singly ionized particles, the charge is equal to that of the electron. For the case of doubly ionized particles...
