Uncovering the effects of grazing exclusion duration on plant richness and biomass in alpine grasslands using the price equation [PDF]
Grazing exclusion is a key strategy for restoring degraded alpine grasslands. However, the mechanisms underlying plant species richness and biomass responses to long-term enclosure, particularly species turnover and biomass redistribution, remain unclear.

Pressure drop mechanisms in a cooling system enclosure
A potential way to reduce the noise generated by construction machinery cooling systems is to satisfy the flow rate required for cooling at lower fan speeds, and a promising approach to achieving this goal involves finding ways to reduce the pressure ...

Expansion Coefficients and Propagation Speeds of Premixed n-Butane–Air Flames
The propagation speeds of premixed n-butane–air mixtures (2.0–5.7 vol%) were investigated under various initial conditions (pressures of 0.4–1.2 bar; temperatures of 289–500 K).

Romano-British Settlement in South-East Wales
Hillforts and defended enclosures do not appear to have played much part in the fighting connected with the Roman occupation of south-eastern Wales. Following the conquest, although a more Mediterranean style of life was introduced around forts and a ...

Enclosure of the Numerical Range of a Class of Non-Selfadjoint Rational Operator Functions [PDF]
In this paper we introduce an enclosure of the numerical range of a class of rational operator functions. In contrast to the numerical range the presented enclosure can be computed exactly in the infinite dimensional case as well as in the finite ...
