Identify the three main threats to biodiversity and explain how each damages diversity? Solution Answer) Three main threats to biodiversity are listed in details below; a) Deforestation and habitat loss - deforestation refers to permanently destructing the forests to make the land of forest be available for other uses. deforestation is performed by large scale burning of forests which makes a large part of unnecessary carbon emission to the environment. deforestation cause the loss in plant diversity (earlier available in those forests) as well as loss in fauna lived in those forests. b) Climate change - change in climatic conditions is a natural process which occurs at a very slow rate. but climate change due to human activities a rapid process which affect the environment in long terms. rapid climate change does not provide sufficient time for adaptation and a large part of biodiversity is lost. particularly, aquatic ecosystem is primarily affected by climate change. such climate change conditions are rising oceanic temperature, high carbon emission in environment, global warming etc. c) Overexploitation - To fulfil the requirements of rapid growing world population, often natural resources are exploited blindfold and over exploiting these resources result in loss of biodiversity such as over-harvesting lead that variety vulnerable to loss in its genetic diversity, overfishing makes that fish species vulnerable to extinction. there are other ways of overexploitation such as killing, hunting, poaching which result in losing diversity of fauna being exploited..

If you take illustrations from some source (including the IEEE Spectrum articles) please make sure this is properly cited. http://spectrum.ieee.org/semiconductors/nanotechnology/the-next-highperformance-transistor- could-be-made-from-lateral-nanowires Describe a FINFET and how it works. How is it different than the planar MOSFET described in the first 5 slides of the TFET lecture? Is the FINFET a quantum device? Give reasons why or why not. How is the nanowire device described here different than the FINFET? Why is this difference an advantage for the nanowire device? They one problem with the nanowire device is capacitive coupling. What is this and explain why it is a problem with the nanowire device? Solution 1) The FinFET technology promises to provide the deliver superior levels of scalability needed to ensure that the current progress with increased levels of integration within integrated circuits can be maintained. The FinFET offers many advantages in terms of IC processing that mean that it has been adopted as a major way forwards for incorporation within IC technology. FinFET technology has been born as a result of the relentless increase in the levels of integration. The basic tenet of Moore\'s law has held true for many years from the earliest years of integrated circuit technology. Essentially it states that the number of transistors on a given area of silicon doubles every two years. Some of the landmark chips of the relatively early integrated circuit era had a low transistor count even though they were advanced for the time. The 6800 microprocessor for example had just 5000 transistors. Todays have many orders of magnitude more. basically what is finfet?? FinFET technology takes its name from the fact that the FET structure used looks like a set of fins when viewed. The main characteristic of the FinFET is that it has a conducting channel wrapped by a thin silicon \"fin\" from which it gains its name. The thickness of the fin determines the effective channel length of the device. In terms of its structure, it typically has a vertical fin on a substrate which runs between a larger drain and source area. This protrudes vertically above the substrate as a fin. The gate orientation is at right angles to the vertical fin. And to traverse from one side of the fin to the other it wraps over the fin, enabling it to interface with three side of the fin or channel. This form of gate structure provides improved electrical control over the channel conduction and it helps reduce leakage current levels and overcomes some other short-channel effects.. The term FinFET is used somewhat generically. Sometimes it is used to describe any fin-based, multigate transistor architecture regardless of number of gates. Due to the increased emphas.

Find an attack that was successful and describe how it could have been prevented. Solution Answer: As per Computer Weekly, social engineering attacks were the most well-known hacking strategy utilized as a part of 2015. What\'s more, there\'s no indication of it backing off; in 2016 60 percent of undertakings were casualties of a social engineering attack or something to that affect. Furthermore, as per EMC, phishing attacks—the least demanding and most normal sort of social engineering attacks—brought about almost $6 billion in misfortunes in 2013 alone, spread out finished around 450,000 separate bargains. Some hurt more regrettable than others, however all brought about a sufficiently genuine shake up for security directors to recalibrate their regard for the vector, investigate their conventions, and make teaching staff a best need. Here\'s our pick for five of the greatest social engineering attacks ever. 5. 2011 RSA SecurID Phishing Attack Security firms ought to be the most secure targets with regards to a data framework attack, yet they are likewise delicious focuses on that draw more than what\'s coming to them of endeavors. In 2011, one of these attacks bit encryption mammoth RSA and prevailing with regards to mesh hackers profitable data about the organization\'s SecurID two-factor validation coxcombs. In spite of the fact that RSA at first denied that the data could enable hackers to trade off anybody utilizing SecurID, protection temporary worker Lockheed Martin soon recognized hackers endeavoring to rupture their system utilizing stolen SecurID information. RSA retreated rapidly and consented to supplant a large portion of the disseminated security tokens. This inconvenience came down to four workers at RSA parent organization EMC. Attackers sent them email with a satirize deliver implying to be at a vocation enrollment site, with an Excel connection titled 2011 Recruitment Plan. It wasn\'t clear why the representatives would think about a spreadsheet from an outsider site, however they opened it—and a zero-day Flash adventure covered in the spreadsheet introduced indirect access to their work machines that soon exposed the keys to the kingdom. 4. 2015 Ubiquiti Networks Scam Not all hackers are searching for touchy data; here and there they simply need chilly, hard money. In 2015, Ubiquiti, a particular producer of wifi hardware and software situated in San Jose, discovered this out the most difficult way possible when their fund division was focused in an extortion conspire rotating around worker pantomime. The organization never uncovered precisely how the attack was organized, yet said that the bookkeeping office got email indicating to be from the organization\'s Hong Kong auxiliary. Regularly, such emails contain guidelines with respect to changes in installment account points of interest or new selle.

Hospital Management Project \"Simple Scenario\" We want to develop a comprehensive software product for XY Hospital, where several doctors are working together. There are several departments in the hospital, but a central administrationoffice is handling the patient appointment tasks. Most patients make an appointment before their visit. However, patients can walk in and can be treated if an appropriate doctor is available. On events, patients may change their visit schedule by calling. A patient who made an appointment but cannot appear should cancel his/her appointment in order to avoid a ‘no-show’ penalty. The appointment clerks in the administration office are handling all the appointments and the scheduling clerks generate ‘daily treatment schedules’ for doctors based on the appointment. The ‘daily treatment schedules’ include doctor’s name, patient’s information, nurses and treatment rooms for each treatment. Hence, doctors are seeing patients according to the daily treatment schedule. Once patients are treated by the doctors, the accounting office in the hospital is responsible for calculating the medical fee, mailing bills and receiving the payments. For the patients who do not pay for a certain period of time, the records of the patients with bad credit are sent to a collection agency. The collection agency is specialized for collecting the fee and enforcing relevant laws. In addition to the routine treatments, the hospital also provides emergency care. For an emergency care, patients do not need to make appointments. Emergency patients are seen by emergency specialized doctors, and later patients may be handed over to an appropriate doctor for further treatments. Read the simple scenario carefully for the project, and answer the following questions: Question No. 1 Briefly describe the objective of the project? [1 mark] Question No. 2 Identify all the stakeholders? [1 mark] Question No. 3 List the main functions that the project provides? [1.5 mark] Question No. 4 Identify the conditions/constrains that the project scenario may has?

Explain a) advantage of promoting outcrossing in plants and preventing self-fertilization, explain b) two (2) neat/cool mechanisms you learned on how plants pollinate others. Make sure you provide enough detail showcasing your understanding of those processes. Explain a) advantage of dispersing seeds, andexplain b) two (2) neat/cool mechanisms you learned on how disperse their seeds. Make sure you provide enough detail showcasing your understanding of those processes. Solution Advantages of promoting outcrossing in plants and preventing self-fertilization: Adding genetic diversity to the species, It will add resistant to diseases, It will help in production of hybrid plants and flowers, which keeps the species strong, It will help in production of large number of viable seeds. There is a possibility to add new desirable characters, Yield of crop can be maintained, It helps in evolution, Undesirable characters of the plant can be eliminated. Mechanisms you learned on how plants pollinate others: 1. Imperfect (or unisexual) flowers and monoecy. The separation of the male sexual part (stamen) and the female part (pistil) into two separate flowers eliminates intrafloral pollination and favors outcrossing. In monoecy (adj. monoecious), or monoecism, both imperfect flowers are borne on the same plant.e.g. pumpkin and squash, melons 2. Imperfect flowers and dioecy. The natural occurence of individual plants bearing either staminate or pistillate flowers ensures cross-pollination. This phenomenon is called dioecy (adj. dioecious). e.g. papaya 3. Dichogamy. Opposite of homogamy, the stamen and the pistil mature at different periods. There are two main types: protandry and protogyny. In protandry, the stamens or anthers develop ahead and the pollen grains mature and are shed before the pistils or the stigma become mature and receptive. Eg: Asteraceae In protogyny, the pistils or stigma mature ahead of the stamens or anthers. e.g. Suaeda; Simpson 4. Chasmogamy. Opposite of cleistogamy, pollen is shed, the stigma becomes receptive, and pollination occurs when the flower opens The opening of the flower exposes the stigma to pollen from other flowers. 5. Hercogamy (or herkogamy). This is the spatial separation of the male (stamens) and female (stigma) sexual organs within a flower. In one type of hercogamy called heterostyly, the heights of stigmas relative to the stamens vary from flower to flower. 6. Self-sterility or self-incompatibility. Self-sterility is the inability of a plant to form functional gametes or sexual structures while self- incompatibility is a condition in which fertilization fails to occur between gametes from the same individual. In both cases, self-pollination does not form a seed and thus seeds that are formed necessarily arise from cross-pollination. ACCORDING TO CHEGG GUIDELINES WE HAVE TO ANSWER ONE QUESTION AT A TIME. POST THE REST AS SEPERATE QEUSTION, THEN I CAN HELP YOU..

Essay question: Camels must cope with hot desert environments where water is scarce and the ambient temperature is often higher than the camel\'s core body temperature. Discuss as many physics-based adaptations as you can think of with which the camel might keep from overheating while minimizing its water loss. You don\'t need to calculate anything, but be sure to discuss the relevance of all of the possible heat transfer mechanisms in play, and the physics of each adaptation. (The adaptations you list don\'t necessarily have to be ones actually used by camels, but rather ones that a camel might have used.) Solution Ectotherms maintain heat production and homeostasis by gaining heat from external environmental sources whereas endotherms maintain heat homeostasis by gaining heat from internal organs for instance in camel\'s heat producing source is liver by various enzymatic reaction due to production of ATP and converted to heat. They obtain physicas based adaptation by gaining heat from inner organs via heat of convection. T = M (metabolic heat rate) – [ R + Conductive heat + convective heat (for camle) + E] Heat Production is the process of gaining heat by metabolic process in camel\'s body Heat loss or heat transfer in camel to outside environment is under the control of the following processes – heat of conduction (W/m2) or heat of convection (W/m2). Endothermic animals such as camels are characterized by warm-blooded nature as they maintain more body temperature compared to outside environment Heat of conduction first observed in camel because camel is going to maintain constant 41C degrees of inner body temperature in desert environment in which heat transfer occurs through its body tissue followed by hair covering the body. Later, heat transfer normally resisted by the thickness of skin layers & the flow of heat is varied according to thermal conductivities. Therefore, the sum of the resistance to heat flow is equal to the total of conduction & resistance effects. Later, a “conduction heat transfer coefficient can be denoted & it is followed by transfer heat into the air where convection and radiation contribute to this step..

1) What are the benefits of DOAS? 2) What is reheat? Why is it required even with VAV sometimes? 3) What is a waterside economizer? Solution Qus 1.Answer The concept of DOAS was introduced in our industry over the past several decades. DOAS is capable of delivering the 100% required outdoor air (OA) to each occupied space independently or in conjunction with local terminal HVAC units. The system is the first recognized system that takes credit for decoupling humidity control and temperature control, which introduced the industry to the potential solution that fulfills ASHRAE Standard 62.1 ventilation requirements. Decoupling the humidity control and temperature control (or decoupling sensible and latent load handling) becomes the major benefits of utilizing DOAS in the early 90s. Operating this kind of primary and secondary system combination with other advanced technologies of that time offered a cost saving advantage and better humidity control when compared to traditional HVAC systems. (Meckler 1986) The primary system delivers primary air at a low temperature (for example at 42° F). Thus, a small quantity of primary air capable of offsetting the building humidity load and fulfilling the ventilation requirement. Under particular building type or climates, the partial sensible cooling load can rely on the primary system in summer or under part-load conditions. The remaining sensible cooling is provided by terminal unit(s) using local recirculation air to maintain the space temperature level. From decoupling the humidity control and temperature control, the most obvious benefit is the ability to downsize the system. Since the primary system is responsible for humidity control and delivering required ventilation air, the low supply air temperature causes a lower total requirement quantity than the system configuration can with a single system handling the required sensible and latent loads. Downsizing the primary system duct and fan size offer a cost savings advantage because the secondary system is only responsible of sensible cooling eliminating the need for humidity control from the secondary system. Benefits of DOAS: Based on current literature review, the benefits of DOAS compared to a conventional VAV system are: 1 Ventilation In order to realize the ventilation benefit of DOAS, the OA must be supplied to each occupied space either directly or in conjunction with local HVAC units. One of the difficulties of achieving good ventilation performance with central HVAC systems (e.g. VAV systems) serving multiple zones is that the individual zone sensible loads do not necessary vary with their ventilation requirement. This causes increased system total ventilation intake airflows - which are often required to ensure the proper ventilation for each zone at all operation conditions - in compliance with ASHRAE Standard. Another difficulty is over-ventilation of non-critical zones. In a multiple-zoned recirculating ventilation system, a single air.

Beadline: 20t6 October\' In 1. Briefly describe the homogencous reaction and heterogeneous reaction, and give examples for each phenomena. (30%) Solution Homogeneous reaction: Chemical reactions that occur in a single phase (gaseous, liquid, or solid) is called homogeneous reaction. The most important of homogeneous reactions are the reactions between gases (e.g., the combination of common gases and oxygen to produce a flame) and the reactions between liquids or substances dissolved in liquids (e.g., the reactions between aqueous solutions of acids and bases). Heterogeneous reaction: Chemical reactions in which the reactants are components of two or more phases (solid and gas, solid and liquid, two immiscible liquids) or in which one or more reactants undergo chemical change at an interface, e.g., on the surface of a solid catalyst. The reaction of metals with acids, the electrochemical changes that occur in batteries and electrolytic cells, and the phenomena of corrosion are part of the subject of heterogeneous reactions..

A patient has breast cancer which has metastasized to their lungs. This is a very common route of metastasis, in which cancer cells are drawn into lymphatic capillaries with lymph, move through the lymphatic system, then gain access to general circulation as the lymphatic ducts empty into venous circulation. Often, the cancer cells then “seed” the first hospitable organ they encounter (often the lungs, for non-GI cancers). Trace the route that cancerous cells took from the left breast, through the lymphatic vessels, and then through circulation, to the point where they invaded the lung tissue. Solution Cancer cells break away from the left breast and attach themselves to the outside wall of any lymphatic capillary. Then, they accomplish themselves in the vessel wall to flow with the lymph carried away for infiltration to reach the lymph nodes. There they start multiplying and blocking the pleural sac (surrounds the lung) which in turn gets filled with fluid or forms a tumor and then slowly these cells invade the lung tissue..
