An old brick has a natural cavity on one side, providing a cool daytime slug hiding place. Look under any you have around the garden and dispose of the slugs found sheltering. Purposely position a few to create slug shelters, and check daily. A brick also makes a handy squishing implement.
Q Angle of the Knee. The Q angle of the knee is a measurement of the angle between the quadriceps muscles and the patella tendon and provides useful information about the alignment of the knee joint.
Definition I: From a triangle. Given any angle q (0 Â£ q Â£ 90Â°), we can find the cosine of that angle by constructing a right triangle with one vertex of angle q. The cosine is equal to the length of the side adjacent to q, divided by the length of the triangle's hypotenuse. In this way, we can find the cosine of any q in the range 0 Â£ q Â£ 90Â°.
