The Measurement Of Strength In Children: Is The Peak Value Truly Maximal?, H. Ozake, T. Abe, Scott J. Dankel, J. P. Loenneke, T. Natsume, P. Deng, H. Naito

College of Science & Mathematics Departmental Research

It is unclear whether the measurement of maximum muscle strength in younger children can be performed accurately due to factors such as motivation and maturity (i.e., the ability to receive instruction). If there is a large change in a ratio between muscular strength and size from the youngest to the oldest, then this might provide some indication that the youngest may not have been able to voluntarily activate their muscles for reasons mentioned previously. The purpose of this study was to observe the ratio between handgrip strength (HGS) and forearm muscle thickness (MT) across differing ages in younger children. A …

Is There A Difference Between Democrat And Republican States In The Percentage Of Male High School Students Who Physically Fight On Campus?, Anthony Brown, Wayne L. Davis

Lincoln Memorial University Journal of Humanities and Social Sciences

School violence is a common occurrence in American high schools. Victims of school violence are more likely than others to become depressed, skip school, and commit suicide. In addition, intimidation, threats, sexual harassment, prejudice, gossip, and ridicule are serious threats to successful education. Overall, about 33% of students are bullied at school by other students, and bullying leads to fights. Because Democrats and Republicans support two different types of social learning environments that will modify the behaviors of residents within their respective jurisdictions, and because public safety is an important social issue, it is important to know if there is …

Political Partisanship And Female High School Students Who Carry Handguns, Trenton Cameron, Wayne L. Davis

Lincoln Memorial University Journal of Humanities and Social Sciences

The United States is a gun culture nation, and gun violence is a serious problem. Because there are more than 280 million guns in America with over 65 million handguns in circulation, the Republicans believe that there are too many guns in America to prevent criminals from illegally obtaining them. In addition, only law-abiding residents will honor gun-control laws. As a result, law-abiding residents will become defenseless, which will promote crime. Democrats, on the other hand, believe that the gun-related crime problem will never be solved until actions are taken to eliminate the availability of handguns. After all, it is …

Digital Humanities At Cuny. Building Communities Of Practice In The Public University, Stefano Morello

Publications and Research

In this essay, I reflect on my experience working in the field of Digital Humanities at The Graduate Center (GC) of the City University of New York (CUNY) to refute the misconception that the point of intersection of humanities and computation is dependent on robust technological infrastructure and, therefore, outside of the reach of underfunded public institutions. On the contrary, my tenure as a GC Digital Fellow suggests that the development of DH communities of practice can be an especially valuable asset for public universities, due to the waterfall effect they can produce for both the academic and the local …

Sustainability As An Effective Strategy For Development Of Human Settlements., Tarek Abou-Ouf, Mohamed El-Mekawy

Mansoura Engineering Journal

Sustainable development has become popular phrase in the 1990. The term came into wide use after publication in 1988 of our common future, the report of the World Commission on Environment and Development, and was further spread after the Earth Summit in Rio de Janeiro in 1992, the concept of sustainable development has been used to evaluate the development projects and rural natural resource management projects in developing countries. Recently, it has been applied to evaluate cities, communities and human settlements on the field of planning and growth management. Developing countries are in great need of sustainable development that meets …

When Vertical Is Horizontal: How Vertical Mergers Lead To Increases In “Effective Concentration”, Serge Moresi, Steven C. Salop

Georgetown Law Faculty Publications and Other Works

This article explains the inherent loss of an indirect competitor and reduction in competition when a vertical merger raises input foreclosure concerns. We then calculate a measure of the effective increase in the HHI measure of concentration for the downstream market, and we refer to this “proxy” measure as the “dHHI.” We derive the dHHI measure by comparing the pricing incentives and associated upward pricing pressure (“UPP”) involved in two alternative types of acquisitions: (i) vertical mergers that raise unilateral input foreclosure concerns (and the associated vertical GUPPI measures), and (ii) horizontal acquisitions of partial ownership interests among …

Library Funding And Physically Challenged Students In Nigerian Universities, Adekoya Clement Ola

Using Instagram Museum Nasional As A Historical Education Media Through E-Publication To Engage Audiences, Fitria Ayuningtyas, Uljanatunnisa Uljanatunnisa, Vinta Sevilla

Library Philosophy and Practice (e-journal)

The museum as an institution devoted to cultural preservation began to utilize social media as a medium of communication to the public. Some museums around the world since the early 2000s have used social media to create a new face or rebrand in giving an update to the public. Generally, the term for museums that utilize technology in practice, is called Museum 2.0. In this research, researchers aimed to explore Instagram content as a medium of historical education through qualitative content analysis. The formulation of the problem in this research is to know how the contents of the National Museum …

Numerical Simulation Of Nonlinear Vibrations Of Discrete Mass With Harmonic Force Perturbation, M. Yusupov, B. A. Akhmedov, Olga Karpova

Acta of Turin Polytechnic University in Tashkent

The problem of vibration of a single-mass system under the force excitation of vibration associated with a fixed base by a weightless nonlinear viscoelastic spring is considered. To take into account the rheological properties of the spring material, the Boltzmann-Volterra principle was used. Mathematical models of the problem under consideration are obtained, which are described by integro-differential equations. A solution method based on the use of quadrature formulas has been developed and a computer program has been compiled on its basis, the results obtained are presented in the form of graphs. The influence of nonlinear and rheological properties of a …

Synthesis Algorithms For Optimal Stable Control Systems With Respect To The Output Variable, S B. Atajоnova, U F. Mamirov

Scientific-technical journal

The article deals with the synthesis of optimal stable control systems with respect to the output variable. A continuous one-dimensional system with the properties of controllability and observability is discretized using the quantization period T and an extrapolator of zero order. The above expressions make it possible to obtain the parameters of the control law of a continuous one-dimensional system when the feedbacks in the control system are linear functions of the state of the object.

Research On Structural Design And Vision System Of Narrow Shallow Water Multipurpose Underwater Robot, Nan Pan, Xiao-Jue Guo, Jun-Bing Qian, Yong-You Luo, Yi Liu

Journal of Marine Science and Technology–Taiwan

In the narrow shallow water area, the underwater environment is complex and changeable, and the water area is narrow. Because of water body flow, various risks and unpredictable conditions, such as turbulence, vortex, disturbance, and so on exist which could seriously interfere with the motion and control of the underwater vehicle. In this way, the automatic stability and flexibility of multi-dimensional motion under external disturbance becomes the basis and requirement of underwater control and operation. In this paper, the structure design of the main body and power system of the narrow shallow water multi-purpose underwater vehicle was proposed to realize …
