To give bike frames their structural strength manufacturers employ a variety of unidirectional carbon fiber prepreg sheets. Each sheet is designated by the fiber orientation as being either a 0Â°, a plus 45Â°, a minus 45Â°, and/or a plus or minus 30Â°.
Sawfish are shark-like rays characterized by long, tooth-studded snouts. Individuals range in size from 2 to 20 feet and can weigh more than 1,000 pounds. Like most sharks and rays, sawfish are exceptionally vulnerable to overexploitation due to their slow growth, late maturity, and small number of young. All seven species worldwide are classified by the International Union for Conservation of Nature (IUCN) as Critically Endangered.
Juvenile bluefish prey on small shrimp, anchovies, killifishes, crabs and silversides (Pottern et al. 1989). Older juveniles and adults prey on schooling fishes, some of which include: croakers, striped mullet, menhaden, sardines, Atlantic bumper and round scad.1975) examined responses of bluefish to thermal stressors. At stress temperatures of 12 C as a thermal minimum, and 30 C as a thermal maximum, swimming speeds in their aquarium population increased to more than 3 times the acclimation rate, and were maintained.
