These properties are used to dynamically create the small leaves at run-time; hence, only view factors between porous objects (not between hundreds of small leaves) need to be calculated and stored.
Then she took a can of lighter fluid and a box of kitchen matches and stepped outside, into our chilly back yard, which was full of leaves needing to be raked.
"Leaves need to be much longer and wider than they are thick to intercept light for photosynthesis and allow gaseous exchange without losing too much water," says Dr Richard Waites from the University of York.
Leaves need to be continuously supplied with water and carbon dioxide to fulfill their photosynthetic function.
Khat leaves need to be fresh, otherwise they lose their potency.
In addition, it can also be hypothesized that, due to numerous hair-like thorns along the midrib on the underside of the leaf, bramble leaves need to be crushed before being swallowed.
In order to get enough DNA (10 20 μg) for Southern analysis from one putative transformant, either several emerging leaves need to be collected or the plant needs to be multiplied via runner proliferation.
Herbs with soft, juicy leaves need to be dried quickly or they will grow mold.
While "grown-up" succulents only need to be watered every second week, or even once a month (depending on the season/heat), the leaves need to be watered constantly without being watered too much.
For example, managers could pool spare HRH in the district, to be allocated to facilities where shortages occurred or if staff leave needed to be covered.
