Thin-walled structures like crash boxes may be used as energy absorption members in automotive chassis. There have been many studies addressing the behaviors of energy absorption members on frontal crash. These researches have attempted to predict the energy absorption and maximum impact load in shell structures. The energy absorption and maximum impact load depend on many parameters including ...

At present, the tubular structural systems are mainly used in tall buildings to withstand earthquake loads. Although it is possible to analyse the structure by finite element methods using standard three dimensional programs, the system is generally time-consuming and expensive in the primary design work. In this paper, for the analysis of Framed-Tube systems, a simple method was studied and de...

The fundamental cause of all chronic diseases is the miasm. Each individual is born with a miasmatic load which predisposes a symptom to a particular illness. In this case of course a malignancy. The miasmatic load can be determined by the study of the patient’s family history or the past history which has been observed by several homoeopaths viz., Kent, Roberts, Charles Wheeler, Foubister, Kas...

M.M. Murray et al. (eds.), The ACL Handbook: Knee Biology, Mechanics, and Treatment, DOI 10.1007/978-1-4614-0760-7_2, © Springer Science+Business Media New York 2013 ACL injuries are increasingly common, with estimates as high as of 400,000 patients each year in the United States sustaining this injury (in comparison with 120,000 patients undergoing hip replacement surgery) [ 1 ]. The ACL injur...

DNA electrophoresis has been a dominant technique in molecular biology for 30 years. The foundation for this common technique is based on a few simple electrochemical principles. Electrophoretic DNA separation borrowed from existing protein and RNA techniques developed in the 1950s and 1960s. For 30 years, common DNA electrophoretic conductive media remained largely unchanged, with Tris as the ...

This paper tries to tell the story of the general linear model, which saw the light of day 200 years ago, and the assumptions underlying it. We distinguish three principal stages (ignoring earlier more isolated instances). The model was first proposed in the context of astronomical and geodesic observations, where the main source of variation was observational error. This was the main use of th...

During the Annual History of Science Society 2013 meeting, a round table on social media, ‘The Pleasures and Dangers of Social Media’, was organised as a part of a continuing conversation about the role that social media plays in providing leads for research, in constructing course syllabi, and even for opening conversations about the role of archives in historical research and what that could ...

The reliability models of the components under the nonstationary random load are developed in this paper. Through the definition of the distribution of the random load, it can be seen that the conventional load-strength interference model is suitable for the calculation of the static reliability of the components, which does not reflect the dynamic change in the reliability and cannot be used t...
