Large mass splittings between new scalars in two-Higgs-doublet models (2HDM) open a key avenue to search for these new states via exotic heavy Higgs decays. We discuss in detail the different search channels for these new scalars at the LHC in the presence of a sizable mass splitting, i.e. a hierarchical 2HDM scenario, taking into account the theoretical and experimental constraints. We provide benchmark planes to exploit the complementarity among these searches, analyzing their potential to probe the hierarchical 2HDM parameter space during LHC Run 2.

"Through my study of population problems in Egypt I became convinced that the only thorough solution is through birth control. This paper uses some data from a study that I did in Egypt in 1947 as a requirement for the Diploma of Social Work in the Cairo School of Social Work. The title of the research was 'Birth Control as a Remedy for the Low Standard of Living in Egypt.' To obtain data, I studied 110 cases that represent three categories of the population. I divided the people into three categories with respect to their educational and cultural status rather than their economic status, because no one can deny the importance of education in understanding and accepting new principles"--Introduction. / Typescript. / "August, 1954." / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Social Work." / Advisor: Ira H.

Language is a form of human expression. It is the way people communicate with one another to express thoughts, ideas, decisions, desires and essentially to relay information successfully. There are numerous types of language, perhaps the most common of which are the written and spoken languages. Other forms include sign language, Braille and even primitive smoke signals. The term language comes via French, from the Latin word lingua meaning tongue. Even today, the spoken language is often referred to as tongue. It is not known exactly when language began or even how it began, although a common theory is that it began as an imitation of natural sounds of animals such as grunts, groans, whistles and barks. What is known, however, is that language changes everyday as it is influenced by human and historical changes. Words that exist in our vocabulary today did not exist for example a hundred years ago. Nor, perhaps, will they exist a hundred years from now. This is the same for all languages around the world, including the Italian language. Since the beginning of Italian history, Italians have spoken innumerable varieties of language. Discussions concerning these countless varieties could continue incessantly; and for this reason it is important to outline immediately the aim of this discussion. Throughout the ensuing chapters, all information gathered and analysed, has been done in order to achieve one aim: to discuss the existence of a standard Italian language in Australia as well as various dialects and regional varieties, and to analyse its promotion since Italian immigration to Australia. There is an immense wealth of information about Italian and English languages and so it is my objective not to be lost in general discussion but rather to adhere to my main aim as closely as possible / Master of Arts in Interpreting and Translation

Supersymmetric extensions to the Standard Model (SM) have many interesting experimental consequences which can provide important hints to the physics beyond the SM. In this thesis, we first study the anomalous magnetic moment of the muon and show that a significant constraint on the parameter space can be obtained from its current experimental value. In the next topic, we study the CP violations in B -> phi K decays and show that the SM and the minimal supergravity model (mSUGRA) cannot account for the current experimental observation. We then show that all the data can be accommodated for a wide range of parameters in models with non-universal soft breaking left-right A terms. In our last topic, which is based on a Horava-Witten inspired model proposed by R. Arnowitt and B. Dutta, we extend their analysis to the full fermion sector of the SM and propose a new mechanism different from the usual see saw mechanism to generate small neutrino masses which are in good agreement with the current neutrino oscillation data.
