energy balance

energy balance

Alternative medicine
A general term for the “harmony” in an individual’s flow of life forces.

Physiology
A state in which the caloric intake equals the energy consumed, such that the body weight is stable.

energy balance

The number of calories consumed as food, minus the calories expended, e.g., during exercise.

Patient care

When consumption exceeds expenditure, a positive energy balance is present, and weight is gained. When consumption is less than energy expenditure, a negative energy balance is present, weight is lost, and risk factors for cardiovascular disease diminish.

Traditionally, subsurface drainage systems with drain depths of 1.75 m or more and drain spacing more than 50 m were implemented in other parts of Iran.

Drainage treatments were: three conventional subsurface drainage systems including drainage system with drain depth of 0.9 m and drain spacing of 30 m ([D.sub.0.9][L.sub.30]), drain depth of 0.65 m and drain spacing of 30 m ([D.sub.0.65][L.sub.30]), and drain depth of 0.65 m and drain spacing of 15 m ([D.sub.0.65][L.sub.15]); a bi-level subsurface drainage system with drain spacing of 15 m and drain depths of 0.65 and 0.9 m as alternate depths (Bi-level), and surface drainage system with drain depth of 1.2 m (Control).PVC corrugated pipes with an outside diameter of 100 mm were used as lateral drains.

Effect of subsurface drainage on water balance and water table in poorly drained paddy fields

The approach flow head loss is affected by the physical properties of this disturbed soil which surrounds the drain, the drain spacing and the drainage materials used.

An analysis of drainage head losses using computer science tools

In permeable soils where drain spacing is wide, a system of open ditches can be used in lieu of pipes.

In the design of WTM systems used solely for drainage, both the depth of the drain and the drain spacing must be specified.

Agricultural profits for this alternative are reduced because shallow drains require closer drain spacing, which increases costs.

Annual corn yields and nitrogen losses were predicted for a 40-year period using the model DRAINMOD for a range of drain spacings and depths.

Drains in depth: studies focus on nitrogen losses from agricultural lands

Trade studies can be performed with this notebook to observe the effect of FET cell size or the effects of the source and drain spacing on junction temperature with the ultimate goal of keeping the FET junction temperature as low as possible.

Simultaneous electrical and thermal modeling of GaAs FETs using a two dimensional partial differential equation solver

This can be achieved by increasing drainage layer thickness or decreasing drainage length (closer strip drain spacing).

Cost-efficient final cover system for landfill closure

* Even using a close drain spacing, it is unlikely that significant depressurisation of the bedrock would have been possible; recharge from the overlying alluvium would have occurred at a rate which was greater than the capacity of the drains

Depressurising pit walls

The threshold drain spacing for each criterion was determined from Figure 5.

Characterization and evaluation of proposed hydrologic criteria for wetlands

The design of the seepage drainage is a continuous operation regime, by establishing the pose depth, the length of the drain, the drain spacing and after that checking the drain in non-permanent function.
