  • The textbook written by Paul Davies in 19891 entitled, The New Physics, commenced with the following opinion. Many elderly scientists look back nostalgically at the first 30 years of the 20th century, and refer to it as the golden age of physics. Historians, however, may come to regard those years as the dawning of the New Physics. The events which the quantum and relativity theories set in train are only now impinging on science, and many physicists believe that the golden age was only the beginning of the revolution....

  • "Show me a man who makes no mistakes, and I will show you a man who has done nothing."—LIEBIG. In this little volume the author gives but his own personal opinions upon the subjects discussed, and although the sentiments are expressed with an assurance born of conviction, yet he claims not infallibility. He has ever been unable to accept the usual explanations of the great physical forces; and the inadequacies of mooted theories have impelled him to efforts for more philosophical interpretations.

  • The pelvic floor consists of muscles and connective tissue. In the past, the components’ relative contribution to the structural support of the pelvic floor and its functions has been a subject of controversy (Corton 2009). With increasing age women can develop vaginal and pelvic organ prolapse as well as symptoms such as stress urinary incontinence, voiding dysfunction, urgency and frequency and nocturia, and may also develop fecal incontinence, obstructive defecation and pelvic pain (Petros 2010).

  • How shall we assess the structural change hypothesis as the basis for inner-city urban poverty? It certainly seems plausible. One has only to walk the former industrial district of any large, older city, from New York to San Francisco, to see its physical manifesta- tions. Yet some nagging problems remain.

  • This commonly used method of procuring furniture and equipment, requires a pool of qualified, interested bidders and clear, detailed specifications in order to achieve the desired result. Since the paperwork required is substantial, it calls for more effort by the bidding agency, and sometimes discourages prospective bidders. The open advertisement policy, typical of competitive bidding, can attract bidders who lack the experience, expertise, and financial stability required for this highly specialized type of project.

  • We suggested the new infrared mechanism of dimensional transmutation that is omitted in the conventional approach and leads effectively to the stochastization of the Faddeev-Popov functional. We have proved the possibilities of such a stochastization in the Abelian version of the collective excitation and showed that the quantization of infrared − → fields k 2 = 0 leads to one of the version of the ”confinement propagator” .

  • Alterations in chromatin packing are not the only physical manifestations of cancer. A cluster of tumour cells will also usually display gross structural changes that pathologists use for diagnosis: cells look visibly deformed and are often enlarged, with swollen and misshapen nuclei; and the chromosomes are distri- buted eccentrically. In an attempt to study these chan- ges more accurately, researchers at ASU’s Biodesign Institute have developed an optical computerized tomography (CT) scan for individual cells.

  • In this paper we introduce the total specialization of an finitely generated module over local ring. This total specialization preserves the Cohen-Macaulayness, the Gorensteiness and Buchsbaumness of a module. The length and multiplicity of a module are studied. 1. Introduction Given an object defined for a family of parameters u = (u1, . . . , um ) we can often substitute u by a family α = (α1, . . . , αm) of elements of an infinite field K to obtain a similar object which is called a specialization. The new object usually behaves like the given object...

  • Among several approaches to teaching and learning a foreign language, Total Physical Response (TPR) is one that simulates the way children naturally acquire their mother tongue. Instructors give commands to students in the new language, and students respond through gestures. This article explores the principle and feature of TPR, and its advantages and disadvantages.

  • Geography can be described as a field of science which is the study of the Earth’s physical features, people, as well as the relationships between people and their environment. Based on collecting and analyzing materials from various sources, the paper analyze the characteristics of major branches in the new trend of geography. In addition, as a basis for the above analysis, we also outline the history of geography and present the traditional and modern methods in geographical research.

  • In this paper, starting from the common foundation of Connes’ noncommutative geometry (NCG) [1–4], various possible alternatives in the formulation of a theory of gravity in noncommutative spacetime are discussed in details. The diversity in the final physical content of the theory is shown to be the consequence of the arbitrary choices in each construction steps.

  • This work is devoted for gauge boson sector of the recently proposed model based on SU(3)C ⊗ SU(3)L ⊗ U(1)X group with minimal content of leptons and Higgses. The limits on the masses of the bilepton gauge bosons and on the mixing angle among the neutral ones are deduced. Using the Fritzsch anzats on quark mixing, we show that the third family of quarks should be different from the first two. We obtain a lower bound on mass of the new heavy neutral gauge boson as 4.032 TeV. Using data on branching decay rates of the Z boson, we can fix the limit to the Z and Z 0 mixing angle φ as −0.

  • In recent years, one of the new applications of the coherent state method was to construct representation of superalgebras and quantum superalgebras. Following this stream, we had a contribution to working out explicit representation of Uq[gl(2|1)]. Up to now, Uq[gl(2|1) is still the biggest quantum superalgebra representations in coherent state basis of which can be built. In this article, we will show some detailed techniques used in our previous work but useful for our further investigations.

  • An ecosystem is a group of animals and plants living in a specific region and interacting with one another and with their physical environment. Ecosystems include physical and chemical components, such as soils, water, and nutrients that support the organisms living there. These organisms may range from large animals to microscopic bacteria. Ecosystems also can be thought of as the interactions among all organisms in a given habitat; for instance, one species may serve as food for another. People are part of the ecosystems where they live and work.

  • The vacuum is fast emerging as the central structure of modern physics. This collection brings together philosophically-minded specialists who engage these issues in the context of classical gravity, quantum electrodynamics, and the grand unification program. The vacuum emerges as the synthesis of concepts of space, time, and matter; in the context of relativity and the quantum this new synthesis represents a structure of the most intricate and novel complexity.
