Define: toxic shock syndrome (TSS) impetigo MRSA Solution Answer: 1. Toxic Shock Syndrome (TSS): It is a severe human disease caused by bacteria Staphylococcus aureus. The bacteria produced superantigens which act as a toxins (mainly Toxic Shock Syndrome Toxin-1) to cause this syndrome. Superantigens are bacterial proteins that stimulate the immune system much more extensively than do normal antigens. As they provoke such a drastic immune response thus, they are termed superantigens. Their action is to stimulate T cells to proliferate nonspecifically through simultaneous interaction with class II MHC proteins on antigen-presenting cells and variable regions on the chain of the T-cell receptor complex. It is most commonly seen in females who use superabsorbent tampons during menstruation. However, the toxin associated with this syndrome is also produced in men and in nonmenstruating women by S. aureus present at sites other than the genital area such as surgical wound infections. Symptoms: Low blood pressure, fever, diarrhea, an extensive skin rash (like sun burn), and ultimately shedding of the skin. 2. Impetigo: It is the most frequently diagnosed skin (superficial cutaneous) infection caused by bacteria Staphylococcuspyogenes and S. aureus. It is most commonly seen in children. Symptoms: The encrusted pustules, crusty lesions and vesicles surrounded by a red border, usually located on the face. 3. MRSA (Methicillin Resistant Staphylococcusaureus): Bacteria Staphylococcus aureus is a cause of considerable morbidity and mortality as a nosocomial or hospital-acquired pathogen since late 1950s and early 1960s. However, penicillinase-resistant, semisynthetic penicillins have proved to be successful antimicrobial agents in the treatment of staphylococcal infections. But it is unfortunate that the staphylococci become resistant through procuring of a chromosomal gene (mecA) that encodes an alternate target protein which is not inactivated by methicillin. The majority of the strains are resistant to several of the most commonly used antimicrobial agents, including macrolides, aminoglycosides, and the beta-lactam antibiotics, including the latest generation of cephalosporins. Thus, MSRA strains have recently emerged as a major, difficult to treat, hospital-acquired infection in humans, therefore considered as super-bug..

Biochemistry homework: Focus concept ripening fruit and the activity tin methyl- The link between the production of methanol in wild type and transgenic tomato esterase, the enzyme responsible for methanol production, is examined in fruit. Prerequisite Enzyme kinetics and inhibition. Background major source ofthis methanol is likely Methanol is produced by fruit during the ripening process. The to be from the enzyme p methylesterase which acts upon pectin methyl esters to de-esterify them and produce methanol and other pectic substances One might assume that the production of methanol is correlated with PME activity, but this has not been firmly established. In this case, the investigators at the Plant Science Department at Rutgers University developed a transgenic tomato which was deficient in PME activity. By comparing the behavior of the transgenic tomato with the wild type tomato, the production of methanol in the ripening tomato fruit may be better understood. Questions breaker (Br), turning (Tru) and red ripe (RR) tomatoes. They also determined the amount of PME protein present by using a Western blot assay, which uses a specific antibody to detect the PME protein. The results are shown in Figure 12.1. What is your interpretation ofthese results? Transgenio ING MG Be Figure 12.1: PME protein levels (A) and activity (B) in wild-type and transgenic tomatoes. (Modified from Frenkel, et al. 1998.) Solution As given in A the protein level of PME is completely negligible in transgenic variety and present in wild type. In wild type variety the protein level in less in the IMG stage as compared to the subsequent stages this is because the expression of PME increases as the ripening of tomato increases. in fig. B : In the case of activity of the PME in the wild type variety increase is shown until it reaches the Tu stage and it starts decreasing in the fully ripening stage since the PME activity is not required to do the ripening. little activity in the transgenic variety is also shown because of the endogenous expression of PME because the PME is only altered not fully knockout.

What is the relationship of the epithelium of the epidermis to the connective tissues layers of the dermis? Describe the boundary between the epidermis and dermis and the various types of connective tissues that compose the dermis. Solution Epidermis is a type of epithelium tissue containing typically thin sheets of cells. Epidermis forms the outermost layer of the skin containing 4 to 5 layers of epithelial cells.The outermost part of the epidermis is comprises of flattened cells in stratified layers overlying on a basal layer (stratum basale) made up of columnar cells arranged perpendicularly. Beneath the epidermis lies the middle layer called dermis layer. It is composed of dense irregular connective tissue and areolar connective tissue such as a collagen with elastin arranged in bundled and woven pattern. This layer comprise of the papillary and reticular layers. Dermis contains connective tissues, vessels, glands, follicles, hair roots and sensory nerve endings. This superficial paillary layer of the dermis, made up of areolar connective tissue like collagen and elastin fibers in a loose mesh, projects itself into the stratum basale of the epidermis to form finger-like dermal papillae. The dermis layer also consists of blood and lymph vessels and nerves, which end in epidermal layer and also hair follicles and sweat glands which project out through epidermis. Thus dermis is the layer of the skin between the epidermic and the subcutaneous tissues, primarily composed of dense irregulat connective tissue. These connective tissue provides cushions to the body from stress.Its area adjoining the epidermis is called as papillary region and the deeper area is known as reticular dermis. Dermis is tightly connected to epidermis through a basement membrane. Papillary layercomprising of mainly collagen, intewines with the rete ridges of the epidermis. Reticular layer consists of irregular connective tissue fibers, densely packed collagen, elantin and reticular fibers. Structurally, dermis comprises of collagen, elastic fibers and fibrillar matrix. It also provides the sence of touch, heat etc..

What is a linked list? What is a linked lists general syntax? Can you give me any tips on using linked lists or any extra general info I may need to know? Solution Linked Lists: It is a collection of data elements. A single linked list points to the next element of the linked list. A double linked list points to both the previous and next elements. For every node in the linked list, it has 2 parts - data and pointer Unlike arrays, linked lists are not stored at continguous location. As compared to arrays, linked lists offer dynamic size (we can add or delete elements from the linked list easily). A disadvantage as compared to arrays being, random access of the element is not possible in a linked list. General Syntax in C: //node struct node { int data; // data element struct node *next; // pointer to next element } Best way to learn linked lists is to implement the data structure along with some basic operations on it: Inserting an element (at the start, at the end, at the middle), Deleting an element (from the start, from the end, from the middle), Counting the number of elements etc..

What do you think are the roles of professional societies in contemporary engineering? Do you expect to join a professional engineering society in the future? Solution Roles of professional societies in contemporary engineering: Engineers have the very unique role for solving social problems using the skills and talent of theirs.They solve the problems using devices, systems and machines.They are responsible for connecting, supplying and protecting the society. One of the key area considered is known as CONNECT. The engineers links communities through transport infrastructure. The roads,railways and aircraft transport systems allow people to travel from one end of globe to other.Also there are technologies like 3G, 4G which enables faster communication with people without any physical transportation.So the Engineers are responsible for connecting people over the globe. The other strand is SUPPLY. The society is not only contributed but also sustained by Water,Gas,Electricity and Sewage Infrastructure.These system are developed by the Engineers which serves the basic needs of everyone. Also another considering aspect is the Protection. There are so many ways in which the engineer is directly or indirectly responsible for protection of the society.The Engineers are responsible for designing the flood defense and military systems.They are also responsible for maintenance of these systems.By inventing such system they become able to protect their country. In addition to these, Engineers are responsible for shaping the future.Their efforts of saving the information and utilizing it on required times has revolutionized the era. Due to the above mentioned roles we can join professional engineering to better shape our society..

What is the compensation depth for phytoplankton? How does it differ from the critical depth? Solution Planktons are two types phytoplanktons and these are weakly swimming and free floating microalgae and photosynthetic whereas zooplanktons are fast swimming and feed on phytoplanktons. The compensation depth for phytoplankton is mainly useful to denote the growth of phytoplankton blooms and it is defined as the depth at which the net growth rate of phytoplankton is zero. The compensation depth of phytoplankton bloom is 0.1 to 1% (above this depth population grows) where solar radiation is going to reach adequately for their survival. The critical depth is defined as the critical depths is differ from it in which the phytoplankton biomass cannot grow adequately after a certain depth interval.

VoIP uses which of the following because network congestion can be such a critical problem? A. Time-division multiplexing B. TCP protocol C. VLANs technology D. Isochronous design Solution D. VoIP is very time sensitive and, as such, should be based on an isochronous design. This means that the entire system must be engineered to deliver output with exactly the same timing as the input. FireWire is another example of a device that contains an isochronous interface. Answer A is incorrect because VoIP does not use time-division multiplexing. Answer B is incorrect because VoIP uses UDP for the voice portion of the call, not TCP. Some implementations of VoIP can use TCP for setup and call control. Answer C is incorrect because VLANs are not used for timing and delay problems, but are used to separate the VoIP from general traffic to make it more secure from sniffing..

The Morse code (see Table 6.10 in book) is a common code that is used to encode messages consisted of letters and digits. Each letter consists of a series of dots and dashes; for example, the code for the letter a is *- and the code for the letter b is -***. Store each letter of the alphabet in a node of a binary tree of level 5. The root node is at level 1 and stores no letter. The left node at level 2 stores the letter e (code is *), and the right node stores letter t (code is -). The 4 nodes at level 3 store the letters with codes (**, *-, -*, --). To build the tree (see Figure 6.38 in book), read a file in which each line consists of a letter followed by its code. The letters should be ordered by tree level. To find the position for a letter in the tree, scan the code and branch left for a dot and branch right for a dash. Encode a message by replacing each letter by its code symbol. Then decode the message using the Morse code tree. Make sure you use a delimiter symbol between coded letters. Implementation Notes: You will need to complete the generic implementation of the BinaryTree data structure first (see slides). Once it is complete, solve the problem above (note that the book uses dots and dashes, we will use the asterisk (*) as the dot, hyphen (-) as a dash, and space ( ) as the delimiter symbol between coded letters). Provide a menu program that asks the user to 1) test output for all morse code letters with their respective translated alphabet letters (make sure you are using the binary tree to do the actual translation, output as a nicely formatted table), 2) enter an input file name to decode morse code and output the translated text to the screen, or 3) enter in a line of morse code through the console to decode morse code and output the translated text to the screen relevenat picture of both the tree diagram and the table of morse code Solution JAVA CODE: import java.io.*; import java.util.*; public class MorseCoder implements MorseCodeInterface { private MorseNode root; /** * constructor to build the tree */ public MorseCoder() { root = new MorseNode(); readTreeInfo(); } /** * reads in the tree info from the text file (helper method) */ private void readTreeInfo() { Scanner input = null; try { input = new Scanner(new File(\"encodings.txt\")); } catch (FileNotFoundException exception) { System.out.println(\"File not found!\"); } while (input.hasNextLine()) { String data = input.nextLine().trim(); if (data.length() > 0) { add(data.substring(1).trim(), data.charAt(0)); } } input.close(); } /** * adds the letter to the tree based on the mcode string (helper method) * @param mcode the string being fed in * @param ltr the letter being added at the node */ private void add(String mcode, char ltr) { MorseNode current = root; String signal = \" \"; for (int i = 0; i < mcode.length(); i++) { signal = mcode.substring(i, i + 1); if (signal.equals(\".\")) { if (current.getLeft() != null) { current = current.getLeft(); } else { current.set.

The Jannuschs operated Festival Foods, a business that served concessions at festivals and events throughout Illinois and Indiana from late April to late October each year. The assets of the business included a truck and servicing trailer and equipment such as refrigerators and freezers, roasters, chairs and tables, fountain service, and signs and lighting equipment. Naffziger and her mother were interested in purchasing the business. They met several times with the Jannuschs and observed the business in operation. According to Mr. Jannusch, the parties had entered into an oral agreement on August 13, 2005, to sell Festival Foods to the Naffzigers for $150,000. For the $150,000, the Naffzigers would receive the truck and trailer, all necessary equipment, and the opportunity to work at event locations secured by the Jannuschs. The Naffzigers paid $10,000 immediately, with the balance to be paid when they received their loan money from the bank. The Naffzigers took possession of Festival Foods the next day and operated Festival Foods for the remainder of the 2005 season. The insurance and titles to the truck and trailer remained in Mr. Jannusch\'s name because he had not yet received the purchase price from the Naffzigers. Naffziger acknowledged that an oral agreement to purchase Festival Foods for $150,000 existed but stated that she could not recall specifically making an oral agreement on any particular date. The parties agreed that the Naffzigers would run Festival Foods as they pursued buying the business. The Naffzigers took possession of Festival Foods, receiving the income from the business, purchasing inventory, replacing equipment, paying taxes on the business, and paying employees. The income from Festival Foods was lower than the Naffzigers expected, and two days after the business season ended, they returned Festival Foods to the storage facility where Mr. Jannusch had stored it in the past. The Jannuschs brought an action for breach of an oral contract against the Naffzigers. The Naffzigers claimed that the deal was not sufficiently definite to be enforceable. Are they correct? Solution The Naffzigers are not correc, t in this case UCC applies and under the UCC an enforceable agreement existed. Truck and trailer were the centerpiece of the contract there fore the Naffzigers need to pay the money to the Jannuschs.
