Percent sign with concentrations

Food concentration normal with no overt adverse signs of TBTO exposure noted in adults. Decreased hatchability and increase in percent of chicks found dead in the shell were noted at 60 and 150 mg/kg food. Egg production and eggshell thickness normal. Abnormal blood chemistry and hepatic EROD noted in parent birds treated with TBTO (Coenen etal. 1992)... 

Various authors have commented on the effect of H bonds on heat of mixing at a single concentration— usually 0.5 mole percent. This gives a single value for the heat of mixing, and its sign can be predicted fairly well. One of the most extensive studies of this type (1313) was discussed in Section 2.4.4 and illustrated by Table 2-XII where the actual trends are compared with those predicted from Table 2-X. 

A 50-year-old male patient with cirrhosis and a history of alcohol abuse since age 12 is admitted to the emergency room with seizures. He is dehydrated, and the physician has ordered an intravenous infusion of magnesium sulfate to reduce the seizure activity. In addition, the patient has hypertension treated with diuretics. When reviewing the laboratory work, the nurse notices that the serum blood urea nitrogen (BUN) and creatinine are elevated. The nurse also notices that the serum sodium concentration is elevated and the potassium level is low. The patient is in no apparent distress, with vital signs of blood pressure (BP) 110/62 mm Hg, pulse (P) 60 beats/minute, respiration (R) 12 breaths/minute, and pulse oximetry showing 88 percent oxygen saturation.
