Stiff stems can catch and hold snow, to the same insulating effect.
Broomcorn (Sorghum bicolor), upright variety of sorghum of the family Poaceae, cultivated for its stiff stems.
Vetiver grass is a clump grass, with erect and stiff stems that grow to as much as 1.2 m high.
Although these stems may ensure greater initial stability, the disadvantage of femoral components extended with relatively stiff stems is that long-term bone resorption is promoted due to stress shielding (Bourne and Finlay 1986, van Lenthe et al. 1997, 2002).
Although it is by no means delicate, it is far less sturdy than modern tetrapoids, whose double sets of chromosomes produce stiffer stems and meatier flowers.
Size and stiffness of the femoral implant are considered to be important factors regarding bone remodeling around hip arthroplasties, and negative bone remodeling is more apparent around larger and stiffer stems (Engh and Bobyn 1988, Huiskes et al. 1992, Sumner and Galante 1992, Wixson et al. 1997, Skoldenberg et al. 2006).
In 100 to 115 days, they should produce stalks that are five to seven feet high, each topped with the long, stiff seed stems used to make brooms.
Within three years, he was specializing in a variety called German porcelain, which comes from the branch of the garlic family known as hard-neck because the bulb has a stiff central stem.
A recently developed strategy is compliant compressive fixation that uses compression, via a short traction bar, to stimulate osteointegration at the bone-prosthetic interface, promote hypertrophy of the loaded bone, and avoid stress bypass of the host bone around a stiff intramedullary stem [ 2].
