What are the role of environmental factors on transpiration and how plants defend themselves against water loss? What are the role of environmental factors on transpiration and how plants defend themselves against water loss? Solution Role of environmental factors on transpiration 1. Relative humidity The loss of water vapour from stomata occurs by simple diffusion. When the atmosphere is very humid, the rate of loss of water vapour is lowered. Wind: When the wind velocity is high, rate of transpiration also increases. Temperature: Warm air hold more water vapour so the rate of loss of water increases with increase in temperature. Light: Opening and closing of stomata is regulated by light. More light result in high degree of transpiration. Soil water content: When there is less water content in the soil , the leaf droops / get dehydrated making the stomata to close resulting in less rate of transpiration. Carbon dioxide concentration When the concentration is high, stomata closes resulting in low rate of transpiration and vice versa. Plants defense mechanism against water loss Plants require water for it\'s survival. So it will have to regulate water loss ( especially during drought) . Several leaf adaptations help to combat water loss. Leaf arrangements play important role, transversely arranged leaves loss more water than perpendicularly arranged ones. Other anatomical features of the leaves such as sunken/vestigial stomata and closely arranged mesophyll cells reduces transpiration. Presence of hair, cuticle(waxy) , gums, mucilage etc on leaf surface help reducing transpiration. During drought, plant hormone abscisic acid play an important role by closing the stomata reducing water loss..

What is the need for a shadow page table? (One or two brief sentences please) Solution Virtualization allows multiple operating system instances to run concurrently on a single computer. Virtualization is the creation of a virtual rather than actual version of something, such as an operating system, a server, a storage device or network resources. Virtualization is where the framework divides the resource into one or more execution environments Even something as simple as partitioning a hard drive is considered virtualization because you take one drive and partition it to create two separate hard drives. Types of virtualization: Storage virtualization: is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device Data virtualization: is abstracting the traditional technical details of data and data management, such as location, performance or format.. Network virtualization: is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others. Server virtualization: the partitioning a physical server into smaller virtual servers. Shadow Tables are objects used to improve the way machines, networks and programs handle information. Shadow page tables are used by the hypervisor to keep track of the state in which the guest thinks its page tables should be. The guest can\'t be allowed access to the hardware page tables because then it would essentially have control of the machine. So, the hypervisor keeps the \"real\" mappings guest virtual -> host physical in the hardware when the relevant guest is executing, and keeps a representation of the page table..

Some commercial airplanes recirculate approximately 50% of the cabin air in order to increase fuel efficiency. The researchers studied 1096 airline passengers, among which some traveled on airplanes that recirculated air and others traveled on planes that did not recirculate air. Of the 515 passengers who flew on planes that did not recirculate air, 106 reported post-flight respiratory symptoms, while 112 of the 581 passengers on planes that did recirculate air reported such symptoms. Is there sufficient evidence to conclude that the proportion of passengers with post- flight respiratory symptoms differs for planes that do and do not recirculate air?

Solution Step 1: Identify issues and/or opportunities for collecting dataordata collection goals what problem are you trying to solve by collecting this data? Step 2:Develop operational definitions and procedures. Here we need to be very clear as to what we are measuring, how it is to be measured, and who is to measure it. Often times we will employ sampling in which case we need to define a sampling plan. . Who will the data be collected about? . Who will the group of interest be compared to? . What locations or geographical areas will the data be gathered from? . What categories will be used to identify the group of interest and comparator group? Step 3 : How should data be collected and What sources of data should be used to collect information? There are several methods of collecting data: online-surveys, phone interviews, focus groups and yes, even dreaded handwritten surveys. Each type possesses its own advantages and disadvantages. Whichever method you use, there are bound to be obstacles to overcome along the way. What sources of data should be used to collect information? Pre-existing or official data Survey data Interviews and focus groups Observed data . Two types of data are used in any field of research: qualitative and quantitative. Qualitative data: Typically, data is called “qualitative” if it is in the form of words, but may also include any information that is not numerical in form, such as photographs, videos and sound recordings. Qualitative methods are aimed at describing a specific context, event, people or relationship in a broad contextual way, by trying to understand the underlying reasons for behaviour, thoughts and feelings. Common qualitative research methods include observation, one-on-one interviews, focus groups and intensive case studies Quantitative data: Typically, data is called “quantitative” if it is in the form of numbers. A quantitative approach can be used to count events or the number of people who represent a particular background. Common quantitative tools include surveys, questionnaires and statistical data (such as Statistics Canada census information). It is important to note that all quantitative data is based on qualitative judgment. In other words, numbers cannot be interpreted by themselves, without understanding the assumptions that underlie them. A good research effort involves the use of both types. Both approaches, while distinct, can overlap and rely on the other to produce meaningful data, analysis and results. Step 4 : Analyze and interpret data and Act on results Explaining the technical steps involved in analyzing and interpreting data is beyond the scope of this guide. An organization will have to determine whether it has the internal capacity and expertise to analyze and interpret data itself, or whether it will need the help of an external consultant. . A summa.

Name the author of 1847 review article that conclusively demonstrated the validity of the \"energy concept.\" Please state the \"energy concept\" that developed in Europe during the first half of the 19^th century. Who was the first person to state the First Law in modern mathematical terms AND in what year was his work published? Solution Hermann von Hermholtz was the author of validity of energy concept in 1847. The energy concept in the first half of 19th century, i.e., the first law is the version of law of conservation of energy, which was adopted for thermodynamic systems. It states that total energy of isolated system is constant, energy can neither be created nor destroyed. It is often stated as the change in the internal energy of closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the system on its surroundings and further the impossibility of perpetual motion machines. Rudolf clausius was the first person to state first law in modern mathematical terms and his well esteemed work was published in 1850..

How is the energy transferred from the source to the load in any electromagnetic circuit? Does the magnitude of the reflection coefficient increase, decrease, or stay the same as you move away from the load on a lossless transmission line? Why? Solution Wave’ is a common term for a number of different ways in which energy is transferred: Waves transfer energy but not mass When we watch surf waves coming into shore, it’s easy to think that individual water particles are moving towards us, but that’s not actually the case. The particles involved in waves move back and forth perpendicularly to the way the wave is going, but don’t move significantly in the direction of the wave. The particles ‘take part’ in the wave by bumping into one another and transferring energy. This is why energy can be transferred, even though the average position of the particles doesn’t change. How does this work? It can help to think of a buoy bobbing in the ocean. The buoy is moved up and down by the waves that pass by it, but doesn’t move directionally across the water. You could also think about a Mexican wave at a sports match. The wave moves around the arena, but the audience members don’t move around with it – they only stand up and sit down (a perpendicular movement to the wave direction). Particles in a water wave exchange kinetic energy for potential energy When particles in water become part of a wave, they start to move up or down. This means that kinetic energy (energy of movement) has been transferred to them. As the particles move further away from their normal position (up towards the wave crest or down towards the trough), they slow down. This means that some of theirkinetic energy has been converted into potential energy – the energy of particles in a wave oscillates between kinetic and potential energy. Thinking about potential energy can help us understand why tsunamis can be so damaging. When a tsunami approaches the shore, it shoals (becomes much higher), so the water particles are displaced further from equilibrium. They acquire a lot of potential energy, and this is released when the wave interacts with land. -------------------------------------------------------------------------------------------------------------------- ------------------------------------------------- The magnitude of reflection coefficeint decreases that the magnitude of the reflection coefficient does not depend on the length of the line, only the load impedance and the impedance of the transmission line. Also, note that if ZL=Z0, then the line is \"matched\". In this case, there is no mismatch loss and all power is transferred to the load. At this point, you should begin to understand the importance of impedance matching: grossly mismatched impedances will lead to most of the power reflected away from the load. Note that the reflection coefficient can be a real or a complex number..
