MENOPAUSE AND PHYSICAL PERFORMANCE – A COMMUNITY BASED CROSS-SECTIONAL STUDY

Maturitas, 2009
The aim of this study was to test whether menopause is associated with decreased physical performance and to determine the risk factors accounting for a decline in physical performance.We recruited 979 women (mean +/-SD age, 48.4 +/- 3.9 y; range, 43-57 y) from a community population in Taiwan.

Analog Electron Physics. Interaction Cross-Sections

2001
The aim of the present communication is to describe briefly the physics of electron interactions in matter and its implementation in general-purpose Monte Carlo (MC) simulation codes. We shall limit ourselves to moderately high energies, say above 1 keV.

Neutrino Cross Sections and Scattering Physics

AIP Conference Proceedings, 2006
Large flux uncertainties and small cross sections have made neutrino scattering physics a challenge. However, a worthwhile challenge, as these tiny particle interactions can teach us a lot about neutrinos themselves, the weak interaction, and nucleon structure. As well, knowledge of these cross sections is crucial input to the growing field of neutrino

Cross-sectional echocardiography: Physical principles, anatomic planes, limitations and pitfalls

The American Journal of Cardiology, 1980
Although M mode echocardiography has achieved a prominent role in the diagnosis and management of patients with cardiovascular disease, the limited area of view afforded by M mode techniques has restricted the application of ultrasound in many areas. The development of two dimensional echocardiography has obviated many of the limitations inherent in ...

Physical activity and the menopause experience: A cross-sectional study

Maturitas, 1994
A randomly selected community cohort of 2000 Australian born women aged 45 to 55 were interviewed on the telephone and information obtained on their health and well-being. These women were divided into pre-, peri-, natural and surgical menopausal groups on their menstrual history.

Injuries Among Slovenian Physical Education Teachers: A Cross-Sectional Study

International Journal of Occupational Safety and Ergonomics, 2013
A cross-sectional study was carried out to examine the frequency and types of serious injuries in physical educators throughout their professional career, in relation to their gender, age and teaching level, certain factors causing the injuries and the consequences of those injuries on their working ability.

Transitions in Quantum Physical Systems—Cross Section

1979
This is the fundamental chapter on scattering theory. Here the concept of transition probabilities is introduced and general formulas for the cross section are derived from the basic assumptions of quantum mechanics. In Section XIV.2, a general formula for the transition rate is obtained, which will be used in Section XIV.5 for the derivation of the ...

Neutron Scatter Physics and Differential Cross Sections

2012
Abstract This chapter examines the details of neutron scatter physics. First, the inverse relation between the line width and lifetime of a nuclear excited state is considered, followed by the derivation of the Breit-Wigner equation for neutron scatter and absorption.
