The problem is that you are reversing the string a few times. The following will do: (defun base8 (n) (let ((t8 (truncate n 8)) (m8 (mod n 8))) (if (= t8 0) (list m8) (append (base8 t8) (list m8))))) EDIT Here's a solution without append, using a helper function.
On average, a kidney weighs approximately 150 to 160 grams and, together, both kidneys weigh about 0.5 percent of total body weight. Usually, the left kidney is slightly larger than the right. These measurements and weights represent the typical ranges of a healthy, adult human kidney.
Is it normal for the right kidney to measure 9.4 cm and left kidney to measure 9.2 cm. Post date: May 6, 2013. I will assume that the measurements that you provide are length as measured by ultrasound testing. The size of the kidney depends on body size. A normal adult male kidney will be at least 11 centimeters long. A normal adult female kidney will be at least 10 centimeters long. The right kidney is often just slightly longer than the left kidney. You should ask your physician to interpret this test for you.
