Both farms, however, can only offer the monopsony price and yield the resulting land demand if l ≥ 2 D i UR (v), which refers to high importance of space σ ≥ 2 (p − v + s) and locally separated markets. 26. For lower values of σ, both farms compete for land and the farm with the higher UR price will capture all or most of the land supply.

The aspect ratio (l/d) is calculated by dividing fiber length (l) by its diameter (d). Fibers with a noncircular cross section use an equivalent diameter for the calculation of aspect ratio. If the fiber's modulus of elasticity is higher than the matrix (concrete or mortar binder), they help to carry the load by increasing the tensile strength ...

Aspect ratio (l/d) is calculated by dividing fibre length (l) by its diameter (d). Fibres with a noncircular cross section use an equivalent diameter for the calculation of aspect ratio. If the modulus of elasticity of the fibre is higher than the matrix (concrete or mortar binder), they help to carry the load by increasing the tensile strength of the material.
