  • In chapter 23, we talked about how foods are digested and absorbed, but what happens to these foods once they enter the blood? Why do we need bread, meat, and fresh vegetables? Why does everything we eat seem to turn to fat? In this chapter we will answer these questions as we examine both the nature of nutrients and their metabolic roles.

  • Temperature effects on the kinetic properties of phosphofructokinase (PFK) purified from skeletal muscle of the golden-mantled ground squirrel, Spermophilus lateralis, were examined at 37 C and 5C, values character-istic of body temperatures in euthermia vs. hibernation. The enzyme showed reduced sensitivity to all activators at 5C, theKa values for AMP, ADP, NH4 + and F2,6P2 were 3–11-fold higher at 5C than at 37C. Inhibition by citrate was not affected whereas phosphoenolpyruvate, ATP and urea became more potent inhibitors at low temperature. ...

  • If we connect a battery across a body, there is a movement of free electrons towards the positive end. This movement of electrons is an electric current. All materials can be classified into three groups according to how readily they permit an electric current to flow. These are: conductors, insulators, and semiconductors. In the first category are substances which provide an easy path for an electric current. All metals are conductors, however some metals do not conduct well. Manganin, for example, is a poor conductor. Copper is a good conductor, therefore it is widely used for cables.

  • Harrison's Internal Medicine Chapter 17. Fever and Hyperthermia Fever and Hyperthermia: Introduction Body temperature is controlled by the hypothalamus. Neurons in both the preoptic anterior hypothalamus and the posterior hypothalamus receive two kinds of signals: one from peripheral nerves that transmit information from warmth/cold receptors in the skin and the other from the temperature of the blood bathing the region. These two types of signals are integrated by the thermoregulatory center of the hypothalamus to maintain normal temperature.

  • This edition is not completely new. The second edition built on the first, and SO does this edition. This work has been almost entirely one of “internationalizing” a work mainly written for the UK. New matter has been added, especially in the areas of analyzers, level and flowmeters, and fieldbus. References to standards are various, ard British Standards are often referenced. International standards are in flux, and most standards bodies are striving to have equivalent standards throughout the world.

  • Nursing in Today’s World: Trends, Issues, and Management, 10th edition focuses on the nonclinical aspects of the professional nursing role. Much of this content is just as critical to practicing safely as is competence in the performance of clinical skills. As nursing steps up to play a major role in the changes brought about by healthcare reform, knowledge of the profession and its place in the healthcare environment has never been more important.

  • Although the fifth edition of this book has seen many author changes, our commitment and direction was clearly stated by, Dr. Helen Cox, in the preface to the fourth edition. We continue our commitment to providing a nursing focus to the process of nursing care. The fifth edition reflects seventeen new and six revised diagnoses accepted by NANDA in 2003 and 2005 and updated information in each chapter. The chapter formats remain the same. We have revised the integration of NANDA, NIC, and NOC terminology to assist with understanding their integration.

  • The first function, sperm cell formation, occurs in the two testes. The formation of sperm requires a temperature that is a few degrees cooler than the temperature of the rest of the body. How is this temperature reduction produced? The testes are suspended within a sac called the scrotum. Because it is not located within the body cavity, the temperature of the scrotum is a few degrees lower than normal body temperature. The scrotum is an adaptation that has evolved to increase the chances of pro- ducing healthy sperm. Inside the testes are a great many tiny tubes, or tubules.

  • A major physiological adaptation of the camel is its ability to allow its body temperature to fluctuate. The normal diurnal variation in a fully hydrated camel does not exceed 2°C and is in the range of about 36 to 38°C. In a 500 kg animal the heat stored as a result of diurnal variation of this order would be about 4.2 x 106 (joules). In dehydrated camels, when considerations of energy and water conservation become more important, temperature variation can be as much as 8°C in the range of 34 to 42°C, but a more normal range is 6°C...

  • In a neutral temperature environment, the metabolic rate of humans produces more heat than is necessary to maintain the core body temperature at 37°C.A normal body temperature is ordinarily maintained, despite environmental variations, because the hypothalamic thermoregulatory center balances the excess heat production derived from metabolic activity in muscle and the liver with heat dissipation from the skin and lungs.

  • In the design of an integrated circuit, the designer is faced with the challenge of having circuits and systems function over multiple operating points. From the point of view of performance, the circuit must meet its speed requirements over a range of voltages and temperatures that reflect the environment that the circuit is operating in. Also while the performance requirement must be met at a set of worst-case conditions for speed, the power requirement must be simultaneously met at another set of worstcase conditions for power....

  • More than 200 polymers are used for electrospinning like silk fibroin (Zarkoob et al., 2004; Sukigara et al., 2003; Jin et al., 2004), collagen (Mathews et al., 2002), chitosan (Ohkawa et al., 2004), gelatin (Ma et al., 2005) etc. In the field of tissue engineering electrospinning technique is applied for the preparation of nanofiber scaffold design. The process is very versatile in terms of use of polymers, non-invasive and does not require the use of coagulation chemistry or high temperature for fiber generation.

  • A truly noninvasive medical measurement is any measurement system that does not physically breach the skin or enter the body deeply through an external orifice. Thus, the measurement of body temperature with a thermometer in the mouth, rectum, or ear canal is considered noninvasive, as is the use of an otoscope to examine the outer surface of the eardrum. Similarly, the opthalmoscope and the slit lamp, which shine light in the eyes to examine the retina and the cornea and lens, respectively, are considered noninvasive procedures....
