Soda Can Calorimeter
Soda Can Calorimeter Energy Content of Food SCIENTIFIC SCIENCEFAX! Introduction Have you ever noticed the nutrition label located on the packaging of the food you buy? One of the first things listed on the label are the calories per serving. How is the calorie content of food determined? This activity will introduce the concept of calorimetry and investigate the caloric content of snack foods. Concepts •Calorimetry • Conservation of energy • First law of thermodynamics Background The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another. This fundamental law was used by scientists to derive new laws in the field of thermodynamics—the study of heat energy, temperature, and heat transfer. The First Law of Thermodynamics states that the heat energy lost by one body is gained by another body. Heat is the energy that is transferred between objects when there is a difference in temperature. Objects contain heat as a result of the small, rapid motion (vibrations, rotational motion, electron spin, etc.) that all atoms experience. The temperature of an object is an indirect measurement of its heat. Particles in a hot object exhibit more rapid motion than particles in a colder object. When a hot and cold object are placed in contact with one another, the faster moving particles in the hot object will begin to bump into the slower moving particles in the colder object making them move faster (vice versa, the faster particles will then move slower). Eventually, the two objects will reach the same equilibrium temperature—the initially cold object will now be warmer, and the initially hot object will now be cooler. -

Conventional Explosions and Blast Injuries 7
Chapter 7: CONVENTIONAL EXPLOSIONS AND BLAST INJURIES David J. Dries, MSE, MD, FCCM David Bracco, MD, EDIC, FCCM Tarek Razek, MD Norma Smalls-Mantey, MD, FACS, FCCM Dennis Amundson, DO, MS, FCCM Objectives ■ Describe the mechanisms of injury associated with conventional explosions. ■ Outline triage strategies and markers of severe injury in patients wounded in conventional explosions. ■ Explain the general principles of critical care and procedural support in mass casualty incidents caused by conventional explosions. ■ Discuss organ-specific support for victims of conventional explosions. Case Study Construction workers are using an acetylene/oxygen mixture to do some welding work in a crowded nearby shopping mall. Suddenly, an explosion occurs, shattering windows in the mall and on the road. The acetylene tank seems to be at the origin of the explosion. The first casualties arrive at the emergency department in private cars and cabs. They state that at the scene, blood and injured people are everywhere. - What types of patients do you expect? - How many patients do you expect? - When will the most severely injured patients arrive? - What is your triage strategy, and how will you triage these patients? - How do you initiate care in victims of conventional explosions? Fundamental Disaster Management I . I N T R O D U C T I O N Detonation of small-volume, high-intensity explosives is a growing threat to civilian as well as military populations. Understanding circumstances surrounding conventional explosions helps with rapid triage and recognition of factors that contribute to poor outcomes. Rapid evacuation of salvageable victims and swift identification of life-threatening injuries allows for optimal resource utilization and patient management. -

NUCLEAR WEAPONS EFFECTS Introduction: the Energy Characteristics and Output from Nuclear Weapons Differ Significantly from Conve
NUCLEAR WEAPONS EFFECTS Introduction: The energy characteristics and output from nuclear weapons differ significantly from conventional weapons. Nuclear detonations exhibit much higher temperature within the fireball and produce peak temperatures of several hundred million degrees and intense x-ray heating that results in air pressure pulses of several million atmospheres. Conventional chemical explosions result in much lower temperatures and release the bulk of their energy as air blast and shock waves. In an atmospheric detonation, such as was deployed in Japan, it is the blast and thermal component of the nuclear explosion that is the major factor in destruction and death, not nuclear radiation, as the public believes. The effective range of immediate harm to humans from nuclear radiation from the atmospheric explosion is much less than the effective range from blast and thermal heating. In order to limit the discussion of weapons effects to elementary terms, this discussion is based upon a single worst-case scenario. Probably the largest weapon that might be employed against a population would have a yield of less than one-megaton (or 1 million tons of TNT equivalent energy or simply 1 MT). However, a crude terrorist nuclear device would probably be in the range of a few thousand tons of TNT equivalent energy or a few KT). The discussion here is based upon a nuclear detonation of 1 MT. Yield: The destructive power of a nuclear weapon, when compared to the same amount of energy produced by TNT is defined as the ‘yield’ of the nuclear weapon. A 20-kiloton (KT) weapon, such as was detonated over Japan in World War II was equivalent in energy yield to 20,000 tons of TNT. -
Energy Equilibrium Energy Balance Calorie Referstoa the Riseintemperature Withathermometer
Energy Balance Energy Equilibrium Did you know that the food we eat provides us with energy? We use energy 24 hours a day, seven days a which means the food really contains 110,000 week. Each person needs a different amount of calories. However, food labels in the United energy, and that amount changes throughout States use Calories (capitalized), which is the our lives. The idea is to consume just enough same as kilocalories. Internationally, the energy energy for our bodies to function; not too much measurement of kilojoules is used. It is another or too little. We need to find a balance between way to measure the same item. One kilojoule is energy burned and energy consumed because approximately equal to 0.25 kilocalories. excess energy is stored in our bodies as fat. To find out exactly how many calories are in The energy we consume is measured in food, scientists can use a bomb calorimeter. A kilocalories (kcal). A kilocalorie is defined as bomb calorimeter measures the heat released the amount of energy required to raise the when food is burned, which provides an estimate temperature of a liter of water one degree of potential energy in the food. The amount Celsius. You may have heard of calories instead of energy an object possibly has is known as of kilocalories. The term calorie refers to a potential energy. The bomb calorimeter is used unit of food energy. This energy is expressed because it mimics the method our body uses to in 1000-calorie metric units, known as a break down food. -

What Are My Calorie, Protein, Fat, & Carbohydrate Needs
What are My Calorie, Protein, Fat, & Carbohydrate Needs? Calorie Needs The Harris-Benedict Equation for Basal Energy Expenditure (BEE) is commonly used to figure energy requirements based on sex, height, weight and age. W = weight in kilograms H = height in centimeters A = age in years Men: BEE = 66.5 + 13.8(W) + 5.0(H) - 6.8(A) Women: BEE = 655.1 + 9.6(W) + 1.9(H) - 4.7(A) Example: Beth is a 47 year-old female. She is 5’5” tall and weighs 147 pounds. What is her BEE? (147 pounds)/(2.2 pounds/kg) = 66.8 kg (65 inches)(2.54 cm/inch) = 165 cm BEE = 655.1 + [(9.6)(66.8 kg)] + [(5.0)(165 cm)] - [(4.7)(47 age)] BEE = 655.1 + 641 + 825 – 221 = 1900 calories If Beth gets regular physical activity, her BEE may need to be multiplied by a factor of 1.2-1.5 to account for extra calories needed during exercise. A factor of 1.2 represents an average amount of activity, where 1.5 would be a very high amount of activity. We’ll say Beth gets an average amount of activity. In this case her needs would be: 1900 calories (1.2) = 2280 calories Protein Needs The American Dietetic Association (ADA) recommends daily protein intake for healthy adults as .8-1.0 g of protein/kg body weight. Example: Jay weighs 168 pounds. How much protein does he need per day? (168)/(2.2g/kg) = 76.4 kg 76.4 kg (.8 g/kg) = 61 g 76.4 kg (1.0 g/kg) = 76 g 61 – 76 grams of protein per day Fat Needs Fat intake should equal 30% of your total days calories. -

Locally, we have continued to drive down our emissions, but we have much more to do. -
Thermophotovoltaic Energy in Space Applications: Review and Future Potential A
Thermophotovoltaic energy in space applications: Review and future potential A. Datas , A. Marti ABSTRACT This article reviews the state of the art and historical development of thermophotovoltaic (TPV) energy conversion along with that of the main competing technologies, i.e. Stirling, Brayton, thermoelectrics, and thermionics, in the field of space power generation. Main advantages of TPV are the high efficiency, the absence of moving parts, and the fact that it directly generates DC power. The main drawbacks are the unproven reliability and the low rejection temperature, which makes necessary the use of relatively large radiators. This limits the usefulness of TPV to small/medium power applications (100 We-class) that includes radioisotope (RTPV) and small solar thermal (STPV) generators. In this article, next generation TPV concepts are also revisited in order to explore their potential in future space power applications. Among them, multiband TPV cells are found to be the most promising in the short term because of their higher conversion efficiencies at lower emitter temperatures; thus significantly reducing the amount of rejected heat and the required radiator mass. 1. Introduction into electricity. A few of them enable a direct conversion process (e.g. PV and fuel cells), but the majority require the intermediate generation A number of technological options exist for power generation in of heat, which is subsequently converted into electricity by a heat space, which are selected depending on the mission duration and the engine. Thus, many kinds of heat engines have been developed within electric power requirements. For very short missions, chemical energy the frame of international space power R&D programs.
