Abstract Life on earth is supported by energy from the sun. This chapter is mainly about the sun ‘s radiation and how it is captured by plants. A short section at the end describes an alternative energy source used by a few exceptional orgamsms.The light from the sun is its most obvious radiation, but is just part of a broad spectrum ...

Surgical Innovation, 2004
Traditional monopolar and bipolar electrosurgery remain very useful in laparoscopic surgery. The need for meticulous hemostasis and the tedium of vessel ligation in advanced cases has propelled the development of new energy source devices that have proved to be remarkably helpful in both laparoscopic and open surgery.

Inverse source problem and minimum-energy sources
Journal of the Optical Society of America A, 2000We present a new linear inversion formalism for the scalar inverse source problem in three-dimensional and one-dimensional (1D) spaces, from which a number of previously unknown results on minimum-energy (ME) sources and their fields readily follow. ME sources, of specified support, are shown to obey a homogeneous Helmholtz equation in the interior of ...

Energy cost and energy sources in karate
European Journal of Applied Physiology and Occupational Physiology, 1995Energy costs and energy sources in karate (wado style) were studied in eight male practitioners (age 23.8 years, mass 72.3 kg, maximal oxygen consumption (VO2max) 36.8 ml.min-1.kg-1) performing six katas (formal, organized movement sequences) of increasing duration (from approximately 10 s to approximately 80 s). Oxygen consumption (VO2) was determined

Energy Analysis of Renewable Energy Sources
Energy Policy, 1991This paper examines the application of energy analysis to the assessment of renewable energy sources. The basic features, terms, conventions and methods of energy analysis which were established during the 1970s are introduced and the value of energy analysis as a means of evaluating new energy technologies is explained in relation to current concern ...

Journal of Minimally Invasive Gynecology, 2013
Energy-based instrumentation has not only facilitated the rapid adoption of laparoscopic surgery, but could be considered essential for the completion of abdominal and pelvic procedures under endoscopic guidance. For decades, relatively simple and generic reusable monopolar and bipolar systems were the only options available.
