Activity and energy expenditure

Canadian Journal of Physiology and Pharmacology, 1990
The influence of small changes in activity on energy expenditure and hence on energy requirements and energy balance is assessed. Evidence from direct and indirect calorimetry suggests that differences in spontaneous minor activity could readily alter 24-h energy expenditure by as much as 20%. This compares with values in the order of 10% for moderate

Activation energy of glucuronide biosynthesis

Biochimica et Biophysica Acta (BBA) - Enzymology, 1974
Abstract 1. 1. UDPglucuronosyltransferase ( p- nitrophenol ) of rat liver was found to be resistant to temperatures up to 50°C in native microsomes. In digitonin- and trypsin-treated membranes the resistance was lowered. 2. 2. The apparent K m for UDPglucuronic acid of UDPglucuronosyltransferase increased with the increasing

Activity and Energy

2016
Think about the last time you went for a walk or had a really great workout. How did you feel? Odds are, you probably felt good.

Physical activity and energy requirements

The American Journal of Clinical Nutrition, 1995
Differences in physical activity represent the largest source of variability in energy requirements, both within and between individuals. Chronic changes in physical activity can produce chronic changes in energy requirements that, if not compensated for, can lead to changes in the level at which body weight and body composition are maintained over ...

Fuzzy Energy-Based Active Contours

IEEE Transactions on Image Processing, 2009
This paper presents a novel fast model for active contours to detect objects in an image, based on techniques of curve evolution. The proposed model can detect objects whose boundaries are not necessarily defined by gradient, based on the minimization of a fuzzy energy, which can be seen as a particular case of a minimal partition problem.

Energy of activation

Journal of Chemical Education, 1969
Spinning a half sphere until it comes to a rest on its flat side serves as an analogy to a system of molecules that must acquire a certain amount of energy until they become products.

Energy Cost of Sexual Activity

Archives of Internal Medicine, 1970
To the Editor. —The article by Hellerstein and Friedman "Sexual Activity and the Postcoronary Patient" (Arch Intern Med 125: 987-999, 1970) deserves comment regarding the inferences about the energy cost of sexual activity. To assess the oxygen cost of sexual activity, the authors have used the heart rate during sexual intercourse and compared it with

Medium reorganization energy and enzymatic reaction activation energy

Journal of Theoretical Biology, 1985
Reorganization and activation energies for charge transfer reactions occurring inside a dielectric sphere have been calculated by solving the problem of polar medium reorganization within and outside a dielectric sphere placed in another infinite dielectric. The dielectric sphere is assumed to simulate a protein globule, i.e. an enzyme molecule. It has

BRAZIL Energy End-user Activity

Strategic Planning for Energy and the Environment, 2002
It is amazing how the Brazilian energy sector has changed these last few years! End-users have a new perception about energy-related opportunities. Higher expectations, more demanding attitude and a mindset-oriented solution are transforming the way of doing business.

Active inference and free energy

Behavioral and Brain Sciences, 2013
AbstractWhy do brains have so many connections? The principles exposed by Andy Clark provide answers to questions like this by appealing to the notion that brains distil causal regularities in the sensorium and embody them in models of their world. For example, connections embody the fact that causes have particular consequences.
