In which component of an HVAC system does a chilled beam save energy? Solution A chilled beam is a type of convection HVAC system designed to heat or cool large buildings. Pipes of water are passed through a \"beam\" (a heat exchanger) either integrated into standard suspended ceiling systems or suspended a short distance from the ceiling of a room. As the beam chills the air around it, the air becomes denser and falls to the floor. It is replaced by warmer air moving up from below, causing a constant flow of convection and cooling the room. Heating works in much the same fashion, similar to asteam radiator. There are two types of chilled beams. Some passive types rely solely on convection whilst there is a \"Radiant\"/convective passive type which cools through a combination of radiant exchange (40%) and convection (60%) which can provide higher thermal comfort levels, while the active type (also called an \"induction diffuser\")[8] uses the momentum of ventilation air entering at relatively high velocity to \"induce\" circulation of room air through the unit (thus increasing its heating and cooling capacity). The chilled beam is distinguishable from the chilled ceiling.The chilled ceiling uses water flowing through pipes like a chilled beam does; however, the pipes in a chilled ceiling lie behind metal ceiling plates, and the heated or cooled plates are the cause of convection and not the pipe unit itself Chilled beams are about 85 percent more effective at convection than chilled ceilings. The chilled ceiling must cover a relatively large ceiling area because it provides heating and cooling mainly by radiant, rather than convective, heat transfe.

how can second messengers amplify a signal initiated by a toxicant or drug? Solution A toxicant or a drug can be considered as the first messenger.When these messengers bind to their respective receptors,they may not always be able to pass through the phospholipid bilayer of the plasma membrane to enter the cell and initiate the signalling process.In such cases, secondary messengers helps to relay the signals from the recepors into the cell and in doing so, they also amplify the signal received.This amplification of a signal is brought about by activating many multi-cyclic kinase cascades and many intracellular signalling processes at a time.Thus for one every receptor that is bound by a drug /toxicant, the signal is amplified many times..

Compare and contrast how the nervous and endocrine systems control body function, with emphasis on the mechanisms by which the controlling signals are transferred through the body and the time course of the response(s) and action(s). Describe the structure of each type of hormone, explain how it is created, give an example and explain how that type is transported in the body, and how it generally works in cells. Amine Peptide/protein Steroid Predict the action of a hormone based on the stimuli that release the hormone and the class of hormone. Describe the roles of negative and positive feedback in controlling hormone release. Describe how receptors mediate hormone action. Explain the role of the hypothalamus in the release of anterior and posterior pituitary hormones. Describe the cascade that results in the release of thyroid hormones. Predict the effects of iodine deficiency. Solution Ans: Compare and contrast how the nervous and endocrine systems control body function, with emphasis on the mechanisms by which the controlling signals are transferred through the body and the time course of the response(s) and action(s). The nervous and endocrine systems differ in their means of communication. Nervous system: Electrical and chemical communication. Fast. Stops when stimulus ceases. Neurons quickly adapt and their reponses decline. Endocrine system: Chemical. Slow. Trickle-down effect. Persistent responses. Describe the structure of each type of hormone, explain how it is created, give an example and explain how that type is transported in the body, and how it generally works in cells. Amines – Monoamines synthesized from amino acids by the removal of COOH group, and retain a nitrogen (epinepherine, norepinephrine, dopamine, histamine, serotonin.). Hydrophilic, mixes with blood plasma. Monoamines (thyroid hormone): acts on nuclear receptors. Enters target cells thru ATP dependent transport proteins. Peptide hormones - (chains of 3-200+ amino chains) and Hydrophilic, mixes with blood plasma. Peptides and catecholamines: hydrophilic, stimulates tatrget indirectly. Binds to cell surface receptors, linked to second messenger systems, such as cAMP (cyclic adenosine monophosphate). Steroid hormones- derived from cholesterol. They are hydrophobic, binds to hydrophilic transport proteins (albumins and globulins synthesized by the liver, and prolongs half-lives.). The receptor associates with the target gene, controls transcription. (estrogen and progesterone are good examples of steroid hormone actions). Predict the action of a hormone based on the stimuli that release the hormone and the class of hormone.The stimuli causing endocrine glands to secrete their hormones in direct response to changing blood levels of certain critical ions and nutrients are called hormonal stimuli. Releasing hormone: any of several hormones produced in the hypothalamus and carried by a vein to the anterior pituitary gland where they stimulate the release of anterior pituit.

Answer 1 and 2 in detail Recently, Kathy Smith, a project manager for a large industrial construction organization, was assigned to oversee a multimillion-dollar chemical plant construction project in Southeast Asia. Kathy had earned this assignment after completing a number of smaller construction assignments in North America over the past three years. This was her first overseas assignment and she was eager to make a good impression, particularly given the size and scope of the project. Successfully completing this project would increase her visibility within the organization dramatically and earmark her as a candidate for upper management. Kathy had good project management skills; in particular, she was organized and highly self-motivated. Team members at her last two project assignments used to joke that just trying to keep up with her was a full-time job. Solution 1) Kathy lacks various characteristics of emotional intelligence including empathy, self- awareness, and social skills. To complete the deadlines of the project Kathy forced her team members to work on the weekends. She failed to understand the requirements of people from varying cultural backgrounds. She used the similar approach of project management that she used to adopt in her home country. Furthermore, Kathy lacked sufficient communication skills that resulted in misunderstandings and conflict among her team members. 2) Out of five different dimensions of emotional intelligence, Kathy lacked social skills and empathy element the most. She failed to understand the requirements and feelings of workers. She forced the workers to work on the weekends. It led to the dissatisfaction and passiveness of the workers. Besides this, she also failed to understand the cultural difference among people from different backgrounds.

When hooked to a battery some electrons in the lower band will not move. When hooked to a battery some electrons in the upper band will move. b) As is seen in the above figure, there are two bands with an energy gap in between. The lower band (called valence) is alomst filled with few available states. The upper band (conduction band) is partiallty filled. This represents a semiconductor which is light. The photon energy has cause some electrons from the valence band to be excited into the conduction band. For a metal, the conduction and valence band overlap. For an insulator the energy gap is huge and electrons from the valence band cannot be excited into the conduction band. Hence the energy band diagram represents a semiconductor in light. Note that in dark, the electrons do not have enough energy to cross the band gap and go into the conduction band. When hooked to a battery the electrons in the lower band do not move. This is beacuse they are tightly bound to the nucleus of the atom. The electrons in the conduction band however are free electrons and are free to move. Hence when hooked to a battery, the electrons drift due to the applied electric field..

Briefly Description 4 application and 4 Mechanism that is used on a steamboat? And how do these applications and Mechanism is applied on a steamboat? Solution Mechanism: Marine steam engine A marine steam engine is a steam engine that is used to power a ship or boat. Propeller A propeller is a type of fan that transmits power by converting rotational motion into thrust. Paddle steamer A paddle steamer is a steamship or riverboat powered by a steam engine that drives paddle wheels to propel the craft through the water. boiler The boiler holds a quantity of water in such a way that most of the heat from the fire can be transferred to the water. The water boils and gives off steam under pressure, so the boiler has the double purpose of transferring heat and containing pressure. The greater the surface area exposed to the fire, the more heat can be transferred to the water ( and the less wasted up the stack ), and the more steam produced. The best way to create this large surface area in a small space is to fill the space with pipes, or tubes. Therefore the heating surface of all steamboat boilers is made up primarily of tubes..
