...Magnetotransport in Modulated Graphene by Rubina Nasir Submitted to the Department of Physics on 25 June 2012, in partial ful…llment of the requirements for the degree of Doctor of Philosophy Abstract Recent experimental as well as theoretical works have shown that it is possible to create periodic, electric as well as magnetic, potentials in graphene. The e¤ects of these potentials on charge carriers in graphene leads to novel physical e¤ects with important consequences for transport. Whereas a strong periodic potential can lead to new Dirac points in the band structure of graphene, a weak periodic potential along with a perpendicular magnetic …eld B introduces a new length scale, period of modulation, in the system in addition to the cyclotron diameter at the Fermi energy. Commensurability of these two length scales leads to new observable physical e¤ects. These e¤ects were observed earlier in transport studies in conventional 2DEG systems realized in semiconductor heterostructures. Our aim is to study these e¤ects in a graphene monolayer in order to highlight the similarities and di¤erences in the two systems, conventional 2DEG and graphene. Therefore, in this thesis we have carried out a detailed investigation of the electrical magnetotransport properties of a one-dimensional weakly modulated graphene monolayer. It is found that the periodic modulation broadens the sharp Landau Levels into bands and they start oscillating with B. The electronic conduction in this system...

Inflammation also affects immune surveillance and responses to therapy. Immune cells that infiltrate tumors engage in an extensive and dynamic crosstalk with cancer cells, and some of the molecular events that mediate this dialog have been revealed. This review outlines the principal mechanisms that govern the effects of inflammation and immunity on tumor development and discusses attractive new targets for cancer therapy and prevention. Introduction The presence of leukocytes within tumors, observed in the 19th century by Rudolf Virchow, provided the first indication of a possible link between inflammation and cancer. Yet, it is only during the last decade that clear evidence has been obtained that inflammation plays a critical role in tumorigenesis, and some of the underlying molecular mechanisms have been elucidated (Box 1)...

Hardy ⁎, Susan P. Williams Information Policy and Practice Research Group, Discipline of Business Information Systems, Faculty of Economics and Business, The University of Sydney, Sydney, NSW 2006, Australia Available online 19 April 2007 Abstract The purpose of this paper is to theoretically and empirically explore how public e-procurement policies are translated into practice. The theoretical argument draws on actor network theory (ANT), coupled with Colebatch’s [Colebatch, H. K. (2002). Policy (2nd ed.). Maidenhead, Open University Press.] social construct of policy, to analyze the actors, actions, and circumstances through which understanding of public e-procurement comes to stabilize (or not) into a coherent policy for action. Drawing on three case studies of central government agencies in Italy, Scotland, and Western Australia, we suggest new intellectual perspectives and methodological heuristics that may assist researchers and practitioners analytical efforts in examining sociotechnical change and the implications for policy development and implementation. © 2007 Elsevier Inc.

It is used by the food industry as a soluble dietary fibre and fat or sugar replacement, and in the pharmaceutical industry as a stabiliser and excipient. It can also be used as a precursor in the synthesis of a wide range of compounds. New uses for inulin are constantly being discovered, with recent research into its use for slow-release drug delivery. Inulin, when in a particulate form, possesses anti-cancer and immune enhancing properties. Given its increasing importance to industry, this review explains how inulin's unique physico-chemical properties bestow it with many useful pharmaceutical applications.

...1. INTRODUCTION 1.1 Sexually transmitted diseases Sexually transmitted diseases (STDs) amongst adolescents are a worldwide growing health problem. Approximately one million people contract sexually transmitted infections every day and 50% of them are adolescents aged 15-24 years (Lazarus, Sihvonen-Riemenschneider, Laukamm-Josten, Wong & Liljestrand, 2010). STDs include many different sexually transmittable infectious diseases such as chlamydia, gonorrhoea, genital herpes, human papilloma virus (HPV), human immunodeficiency virus (HIV), and syphilis. An STD is transmitted through vaginal, oral and anal sexual contact as well as through blood products. STDs can also be transmitted from mother to child during childbirth. Untreated chlamydia and gonorrhoea can lead to salpingitis for women and to epididymitis for men, which can affect fertility and in worst case lead to sterility. Hepatitis B, genital herpes, HPV and HIV are still incurable infections. HPV can lead to cervical cancer and HIV to premature death. The only way to protect oneself from contracting an STD is consistent condom use (Vårdguiden, 2011). Another term that is used in the literature is STI (sexually transmitted infection), which refers to the infection itself, whereas STD, which is the term that will be used in this paper, refers to the disease caused by an infection (TeenHealthFX, 2009). 1.2 Knowledge of STDs among adolescents A study based in Northern Thailand by Paz-Bailey et al. (2003) showed that...

...Journal of Behavioral Studies in Business Marketing to the Generations, Page 1 Marketing to the Generations Kaylene C. Williams California State University, Stanislaus Robert A. Page Southern Connecticut State University ABSTRACT Each generation has unique expectations, experiences, generational history, lifestyles, values, and demographics that influence their buying behaviors. Accordingly, many companies are reaching out to multi-generational consumers and trying to understand and gain the attention of these diverse buyers. Multi-generational marketing is the practice of appealing to the unique needs and behaviors of individuals within more than one specific generational group, with a generation being a group of individuals born and living about the same time [1]. This means that marketers need to understand the six U.S. generations: Pre-Depression Generation, Depression Generation, Baby Boomers, Generation X, Generation Y, and Generation Z. When a marketer factors in the different characteristics and behaviors of the generations, it should be easier to build relationships, gain trust, and close business. [2, 3] As such, an understanding of multigenerational marketing is very important to the marketer. The purpose of this paper is to describe briefly the U.S. generations in terms of the times in which they grew up as well as the characteristics, lifestyles, and attitudes of the group. However, the primary focus of the paper is to describe various marketing...

Received 30 March 2011; accepted 17 May 2011 a b Abstract The strength of concrete is a function of the proportions of the constituent materials, namely, cement, water, fine and coarse aggregates. The conventional methods used to determine the mix proportions that will yield the desired strength, are laborious, time consuming and expensive. In this paper, a mathematical method based on modified regression theory is formulated for the prediction of concrete strength. The model can prescribe all the mixes that will produce a desired strength of concrete. It can also predict the strength of concrete if the mix proportions are specified. The adequacy of the mathematical model is tested using statistical tools. Keywords: Concrete; Regression theory; Prediction; Mix ratios. 1. Introduction Concrete is a composite construction material consisting of water, cement, fine aggregate (sand) and coarse aggregate. Mix design of concrete is a means of producing the most economical and durable concrete that meet with certain properties...

...Chaotic Growth with the Logistic Model of P.-F. Verhulst Hugo Pastijn Department of Mathematics, Royal Military Academy B-1000 Brussels, Belgium Hugo.Pastijn@rma.ac.be Summary. Pierre-Fran¸ois Verhulst was born 200 years ago. After a short biograc phy of P.-F. Verhulst in which the link with the Royal Military Academy in Brussels is emphasized, the early history of the so-called “Logistic Model” is described. The relationship with older growth models is discussed, and the motivation of Verhulst to introduce different kinds of limited growth models is presented. The (re-)discovery of the chaotic behaviour of the discrete version of this logistic model in the late previous century is reminded. We conclude by referring to some generalizations of the logistic model, which were used to describe growth and diffusion processes in the context of technological innovation, and for which the author studied the chaotic behaviour by means of a series of computer experiments, performed in the eighties of last century by means of the then emerging “micro-computer” technology. 1 P.-F. Verhulst and the Royal Military Academy in Brussels In the year 1844, at the age of 40, when Pierre-Fran¸ois Verhulst on November c 30 presented his contribution to the “M´moires de l’Acad´mie” of the young e e Belgian nation, a paper which was published the next year in “tome XVIII” with the title: “Recherches math´matiques sur la loi d’accroissement de la e population” (mathematical investigations of the law of...
