The Italic School in Astronomy： From Pythagoras to Archimedes

It is argued that it has not yet been able to value the historical, philosophical and epistemological travail, represented by the filth and fourth centuries BC of the ancient Greek world, which preceded the highest scientific heritage, represented by the so-called golden age of Euclid, Archimedes and Apollonius, Ⅲ-Ⅱ century BC. Well, it is believed that with our complex concept of tradition of thought within which we insert not only epistemological concepts but also philosophical principles, historical and social frameworks, in stasis or in strong movement, processed by us, it is possible better interpret that happy moment of scientific constructions of the third and second century BC, as a result of the valorization of the deep travail and serious battle that preceded it between the fourth and fifth century BC. It is investigated in particular in our paper the development of astronomical thought between the fifth and fourth centuries BC, in the ancient Greek thought, and at last a particular presumed criticism by Archimedes in his Sandreckoner to Aristarchus.

Knowledge, transfer, and innovation in physical literacy curricula

Literate individuals possess knowledge and skill and can apply these to perform tasks in novel settings. Knowledge is at the heart of physical literacy and provides the foundation for knowing what to do and how and when to perform. In this paper I argue that physical literacy includes not only knowledge for performance but also the ability to apply knowledge and use knowledge for innovation. Scholars since the 1930s have addressed the role of knowledge in physical literacy designing curricula centered on transmitting knowledge through a range of interdisciplinary approaches to physical education. This emphasis on physical literacy curricula continues today in the Science, PE, ＆ Me.t and The Science of Healthful Living interdisciplinary curricula.

Science of empirical design in mining ground control

Many problems in rock engineering are limited by our imperfect knowledge of the material properties and failure mechanics of rock masses. Mining problems are somewhat unique, however, in that plenty of real world experience is generally available and can be turned into valuable experimental data.Every pillar that is developed, or stope that is mined, represents a full-scale test of a rock mechanics design. By harvesting these data, and then using the appropriate statistical techniques to interpret them,mining engineers have developed powerful design techniques that are widely used around the world.Successful empirical methods are readily accepted because they are simple, transparent, practical, and firmly tethered to reality. The author has been intimately associated with empirical design for his entire career, but his previous publications have described the application of individual techniques to specific problems. The focus of this paper is the process used to develop a successful empirical method. A sixstage process is described: identification of the problem, and of the end users of the final product; development of a conceptual rock mechanics model, and identification of the key parameters in that model;identification of measures for each of the key parameters, and the development of new measures(such as rating scales) where necessary; data sources and data collection; statistical analysis; and packaging of the final product. Each of these stages has its own potential rewards and pitfalls, which will be illustrated by incidents from the author's own experience. The ultimate goal of this paper is to provide a new and deeper appreciation for empirical techniques, as well as some guidelines and opportunities for future developers.

Complexity and Sociology

This study focuses on the correlation between sociology and complexity and it operates a reflection on the deep epistemological and ontological meaning of complexity, revealing how complexity goes beyond the analysis of the global society and is linked to sociology itself and to the issue of its scientific trait. The study shows how complexity, rediscovered following the globalization processes, reconnects sociology with its own origins and concerns the issue of the relation of sociological science with its own object, that is to say, society and social order. In a more radical manner, the challenge of complexity is intertwined with the road of revisiting modern science and epistemological identifying among ＂order＂, ＂intelligibility＂, and ＂science＂. In such a vision, complexity, not only reconnects sociology to its obiect, but highlights how those traits considered as non-scientific residue of human and social sciences belong to the fundamental issue of scientific knowledge. The challenge of complexity is outlined, as questioning the idea according to which the ＂modern＂ science depletes the ＂scientific vision of the world＂.

Study on the Organic Correlation of Prana Energy

Since India＇s philosophical discussion on the correlation between the mind and the body, the goal achieved through practice has been imbued with much meaning under the influences of yoga. Self-transcendence can be reached through self-discipline that is founded upon the fundamental change and potential for existential practice. The mind and the body do not comprise a binary relationship but instead maintain an intimate relationship bound by the medium of organic energy of breathing, breath, and pr^0a. Of these medium that form the relationship, the pr^-0a has a natural healing tendency, which has been well documented within classics such as Upani.sads and Bhagavad G^ta. Classic yoga explains that pr^0a imbues within it a vivacious passion and energy that will connect the human body with the human mind. Thus, the pr^0a functions as bio-energy. From ancient Indian philosophy to Buddhism, yoga therapy actively utilizes practice as a main element. In particular, the Patafijali yoga＇s methodology details the organic correlation within its eight limbs （支） yoga practices. The prana is breath. This is the only sense in which Patafijali has used this word. Breath is called prana because it moves on continuously throughout the body and reaches the basic circle of the individual self. It pervades mouth, nostrils, heart, navel region and toes. As a result, it is a healing method that achieves far more than the scientific healing methods common in society.

Differences inthe Level of Social Status of Male and Female Folk Dancers

The research was conducted in order to determine differences in the social status structure of male and female performers of folk dances. For the purpose of determining the social status structure of male and female dancers, 103 male and 145 female dancers aged 18-28 actively engaged in folk dancing were tested. For the assessment of social status, only one model that allows for true scientific approach to studying the structure of stratification dimensions has been made so far. The model was constructed by Saksida and later served as a basis for many studies conducted by other authors as well （Saksida, Caserman, Petrovic, Momirovic, and Hosek）. Designed as a phenomenological model, it has undergone several changes over time, but it is still suitable for studying social change. The INST2 questionnaire modified by Boli, Popovic, Hosek, Momirovic, and Savic （SSMIN） was applied in this study. All the data obtained in this research were processed at the Multidisciplinary Research Center of the Faculty of Sport and Physical Education, University of Pristina, through the system of data processing programs designed by D. Popovic and K Momirovic. To determine differences between the groups, a method of discriminant analysis was applied.

Meanwhile, it will promote the teaching reform and improve the level of education in our country.

The Ontology of Counter Factual Causality and Conditional

The author is interested here in the examination of the ontological justification for counterfactual causality and conditional. Ontology metaphysically has to do with what exists and what does not exist. about objects in their associated and individual existence. It is an attempt to further philosophy of causality scientific law, and theory of confirmation and establish a link counter factual. In terms of realism, it is the search for adequate among if-then ＂〉＂ and

Plants as Objects： Challenges for anAesthetics of Flora

This paper presents the conceptual challenges to an aesthetic model of living plants based in embodied interaction with flora through smell, taste, touch, sound and sight. I argue that the science of aesthetics is deterministically visual. Drawing from theories of landscape aesthetics put forth by Carlson and Berleant, I outline four primary obstacles to an embodied aesthetics： plants as objects of sight, plants as objects of art, plants as objects of disinterestedness and plants as objects of scientific discourse. A multi-sensorial aesthetics of flora requires auto-centric proximity and degrees of intersubjectivity between the appreciator and the appreciated plant that raise important philosophical questions about aesthetic experience of the natural world.

The Four Different Aspects of Man-World Relations and the Ontological Nature of Culture

In traditional philosophy, man is usually treated as a subject of knowledge, not as a subject of activity. This naturally led to an ignorance of his creative side and had its echoes in the models of the world put forward. Thus, when the world was mentioned the world meant was that perceived by man and the world man created or planned to create himself was given either a secondary treatment or else it was completely forgotten. But, as man is carrier of active spirit, the things he creates have their place in this world along those created by God. It is without doubt that things created by man are not produced against God＇s will. Still, human creativity is the corruption of the original creation, of the harmony of the world, of the book of nature. Man brings order, so to speak, to the world. He achieves this however at the cost of corrupting the Great Order within some narrow limits. Man himself is among the many highly interesting books written before and there exist as many variations of this book as there are human beings. What is the most difficult for man is though, to read his own book, to understand himself. In this article, the concept of the culture as a human creation is analyzed in the light of Man-World and Man-Nature-God relations. In this case, the author firstly explains the four different world models and then determines the boundaries of science and culture, as well as the individual and social strata of culture.

A Strategy to Strengthen the US Economy

For decades, the United States＇ competitive position in global manufacturing has steadily declined. Analysts point to increasingly automated manufacturing processes, changing domestic demand factors, outsourcing, and over confidence in service export surplnses. However, Asian and European competitors, undergoing the same pressures, have been able to maintain a healthy percentage of their GDP in manufacturing by growing high techjobs while the United States continues to fall behind, Perhaps the most flmdamental and overlooked contribution to this decline is the lackluster performance of the United States education system. After comparing the performance of US students to that of the other G-8 nations in the critical disciplines of math and science literacy, US students rank last. Furthermore, the most recent PISA test results show US students rank in the bottom half of 30 participating nations in the ability to apply math and science concepts to real world problems. This is particularly troubling when one considers that among the compared nations, the US spends the most on math and science teacher compensation. If the US intends to successfully compete in the global manufacturing arena, significant changes to the education system must be enacted. A new strategy aligning the system with real world demands should begin with a national initiative to increase Pre-K enrollments, a paradigm shift from liberal arts to math, science, problem solving and critical thinking, standardized policies aligning high school graduation requirements with college and work place expectations, and standardized college and career readiness assessment programs. These steps combined with more rigorous secondary education teacher certifications, continued education and involvement with universities and manufacturing f＇mns within the community, should more adeq^tely prepare high school students for further study or to enter the skilled workforce. At the post secondary level, federal and state funding should be targeted to R＆D programs specificly to industrial design, engineering, and alternative energy. Industry investment in such programs should be federally incentivized to foster cooperative relationships between business and academia. Such relationships will ensure faculty spend time focusing on how their discipline relates to manufacturing and instilling the necessary skill sets, knowledge and abilities which graduates will need to compete in the global market. Such a revised system will position the US to create and keep high paying manufacturing positions on its way to sustainable economic growth.

Study on Landslide Surge in Reservoir Area

Landslide surge is a fluid-solid coupling problem involving multidisciplinary intersections such as landslide dynamics, fluid mechanics and mechanics along the way, which has important research value.

Efficient synthesis of 1,6-hexamethylene diurethane through coupling transesterification and methoxycarbonylation with methyl phenyl carbonate as intermediate

A reaction coupling system of transesterification and methoxycarbonylation with methyl phenyl carbonate （MPC） as intermediate was established to efficiently prepare 1,6-hexamethylene diurethane （HDU） from 1,6- bexametbylene diamine （HDA）. The feasibility of the system was explored using the thermodynamics analysis, the reaction mechanism and the experiment results. The optimal reaction was carried out to get higher HDU yield. The thermodynamic analysis showed that the metboxycarbonylation of HDA with MPC, the Gibbs free energy of which was negative, was a spontaneous process. Furthermore, the equilibrium constant of the methoxycarbonylation of HDA with MPC was much greater than that of the transesterification of dimethyl carbonate （DMC） with phenol, so the reaction coupling could be realized under mild conditions. The reaction mechanism analysis indicated that phenoxy anion was the key spedes for reaction coupling. Higher MPC concentration was detected when sodium phenoxide was used as transesterification reactant with DMC, since the phenoxy anion of sodium phenoxide could be dissociated more easily. Sodium pbenoxide was more suitable to prepare HHDU through reaction coupling. A yield of HDU as high as 98.3% could be reached under the optimal conditions of mPhONa/mDMC = 0.027 and nDMC/nHDa = 8/1 at 90 ℃ in 2 h.

Systematic Innovation,Comprehensive Development and Going Global:Some Thoughts on the Construction of an Innovation System for Philosophy and Social Sciences in China during the “12 th Five-year Plan” Period

In the past three decades, the great practice of intellectual emancipation and reform and opening up in China has given rise to five achievements in philosophical and social science innovation, opening a new era of theoretical innovation. The 12th Five-year Plan period （2011-2015） will witness the arrival of a new stage of systematic innovation in philosophical and social science research： innovation in individual opinions and conclusions will develop into innovation in fi.mdamental theories, theoretical systems and methodologies; the innovation of individual disciplines and perspectives will give way to the rise of new groups of subjects and to innovation based on synthesized and interdisciplinary studies; and disorderly competition will be replaced by orderly progress. As an important component in the construction of an innovative nation, the building of an innovation system and innovation capacity is as important in philosophy and social sciences as in their counterpart, the natural sciences; they are like the two wings of a bird or two wheels of a cart. Our innovation plan for philosophy and social sciences should strengthen ＂national consciousness,＂ establish ＂national aims＂ and launch ＂national projects.＂ Systematic innovation, comprehensive development and going global constitute the basic tasks of contemporary Chinese philosophy and social sciences.

Special Topic on Ionic Liquids： Energy, Materials ＆ Environment

Ionic liquids （ILs） are organic salts with low melting points, which have many unusual properties like negligible vapor pressure, good thermal stability, non-flammability, wide liquid range and electrochemical window, and excellent solvation power for both organic and inorganic substances. The unique characteristics of ILs endow them with great potential for applications in different fields including chem- ical reactions, extraction and separation, material science, renewable energy, environment, and photoelectric trans- formations. Their properties can be tuned to suit various applications by changing the structures of the cations and/or anions.

Compressor and Turbine Multidisciplinary Design for Highly Efficient Micro-gas Turbine

Multidisciplinary design optimization （MDO） is widely employed to enhance turbomachinery compo- nents efficiency. The aim of this work is to describe a complete tool for the aero-mechanical design of a radial in- flow turbine and a centrifugal compressor. The high rotational speed of such machines and the high exhaust gas temperature （only for the turbine） expose blades to really high stresses and therefore the aerodynamics design has to be coupled with the mechanical one through an integrated procedure. The described approach employs a fuUy 3D Reynolds Averaged Navier-Stokes （RANS） solver for the aerodynamics and an open source Finite Element Analysis （FEA） solver for the mechanical integrity assessment. Due to the high computational cost of both these two solvers, a meta model, such as an artificial neural network （ANN）, is used to speed up the optimization design process. The interaction between two codes, the mesh genera- tion and the post processing of the results are achieved via in-house developed scripting modules. The obtained results are widely presented and discussed.
