Damariscotta Lake
Damariscotta Lake, the link between the towns of Jefferson, Newcastle, and Nobleboro, has always had a unique allure. Each spring, thousands of alewives return from the Atlantic Ocean to struggle up the fish ladder at Damariscotta Mills and reach their traditional spawning grounds. Many early settlers made a living through shipbuilding, milling, farming, and harvesting ice, wood, and alewives. In the 20th century, the establishment of children's camps, fishing lodges, cottages, and homes relied on the lake's draw for recreation. The area has been a destination for notables such as Arthur Godfrey and Thomas Watson, writers Henry Beston and Elizabeth Coatsworth, and Pulitzer Prize winners Robert Lowell and Jean Stafford.
Functional Verification of the Apollo Urine Transport System
A simulated aerospace study was conducted to assess the biochemical effects of space flight by determining the volume of urine output of each crewman. The Apollo urine transport system (UTS), using a radioisotope, tritium, dilution technique, was tested by four human male subjects. The Apollo UTS met minimum requirements for 14 days even when a single unit was used by four individuals. The best individual performance by a subject gave a ratio of 101.4 plus or minus 4.6%. The overall value for volume measurement from the four subjects was 100.6 plus or minus 4.6%. Any void volume may be calculated by this radioisotope method with the UTS system plus or minus 10% of its volume at the 95% confidence level. One experimental error was the incomplete mixing of the radiosotope. The practicability of this procedure in actual space missions still has to be determined. (Author).
Concepts and Trends in Global Education
This publication addresses trends and issues in global education, providing information about what global education is and how to teach it. The publication emphasizes ERIC resources. It offers ERIC Digests about global education and selected items from the ERIC database that exemplify different viewpoints and approaches to global education. It contains a directory of key organizations and World Wide Web sites that provide teacher resources. Designed as a guide for educators who want to include global education across the various subjects of the curriculum, the volume is divided into four parts: (1) "Overview of Global and International Education"; (2) "Institutionalizing Global Education"; (3) "Curriculum, Methods, and Approaches"; and (4) "Appendices." Information about documents in the ERIC database and how to submit documents for the database is appended. (BT)
Biochemical and Physiological Evaluation of Human Subjects in a Life Support Systems Evaluator
A 6-week study with four college students as volunteer subjects was conducted for the purpose of evaluating the nutritional requirements of individuals undergoing stresses imposed by simulated aerospace conditions. A 4-day cycle diet of fresh foods was served at room temperature each day; it was comprised of 110 g of protein, 315 g of carbohydrate, 80 g of fat and 2621 calories. All the clinical data were in the normal range and no significant differences were observed between control and the confinement in the Life Support Systems Evaluator. Metabolic balances show excellent adjustment to the diet; all subjects were in positive nitrogen balance. Physiological measurements of heart rate, blood pressure and oral temperature were in the normal ranges. Minimal body weight changes were observed indicating that the diet was adequate.

The Biochemical, Physiological, and Metabolic Evaluation of Human Subjects in a Life Support Systems Evaluator and on a Liquid Food Diet
A 6-week study with 4 students as volunteer subjects was conducted to evaluate their water, caloric, and protein requirements under simulated stresses of aerospace. The subjects spent 28 days in the Life Support Systems Evaluator; 2 subjects wore the MA-10 space suit, unpressurized, for 8 hrs a day. They ate a 1-cycle, 4 meal per day, fresh food diet and a 1-cycle, 4 meal per day, liquid food diet. The only variety in the fresh food diet was the meat and fruit served at each meal. This diet was highly acceptable and did not show monotony even after 21 days. Flavors were the only variety in the liquid food diet: Cherry, vanilla, chocolate, and strawberry. This diet was unacceptable and monoto...
The Biochemical, Physiological, and Metabolic Evaluation of Human Subjects During a Simulated GT-7 Mission
Four human male subjects were confined for six weeks during which time they participated in a simulated Gemini 14-day flight. They ate a diet of bite sized compressed foods for 30 consecutive days; 14 days were spent in a Life Support Systems Evaluator. This diet was organoleptically unacceptable. It was significantly less digestible than the fresh food diet and caused an increase in fecal void frequency and a significant increase in fecal mass. The protein in the diet was sufficient to maintain the subjects in positive balance for nitrogen but the mineral content (except magnesium) was inadequate. The subjects were in negative balance for sodium, potassium, phosphorus, calcium, and chloride...
