What kind of state information is maintained by an FTP server? Solution In a FTP session, the user should be sitting in front of one host machine and wants to transfer files to or from a remote host. In order for the user to access the remote account, the user must provide user id and a password. After the authorization information is provided and correct, the user can transfer files from the local file system to the remote file system and vice versa. The FTP server sholud maintain state about the user. Server must associate the control connection with a specific user , and the server must keep track of the user\'s current directory as the user knows about the remote directory. Keeping track of this state information of each user and every session, the total number of session that FTP can maintain simultaneously..

Why is there no blood supply that extends into the epidermis? Thanks. Why is there no blood supply that extends into the epidermis? Thanks. Solution Answer: The epidermis has a stratified squamous epithelium, which normally undergoes ecdysis or moulting & do not require nutritious supply so that there no blood supply that extends into the epidermis. Epidermis is the outermost layer of the skin made of keratinized stratified squamous epithelial tissue in which outer or apical surface cells are hardened or dead. It does not contain blood vessels (not vascularized), and the dermal layer supplies oxygen and nutrients by means of diffusion. The layer of the epidermis that contains transulacent cells filled keratin are often referred as “thick stratum lucidum”. The other layers often sloughed off from the surface composed of dead cells that are flat and filled with keratin often referred as “stratum corneum”.

Which of the following protocols was developed in the mid-1970s for use in Systems Network Architecture (SNA) environments? A. SDLC B. ISDN C. LAP-B D. X.25 Solution A. The Synchronous Data Link Control (SDLC) protocol was developed in the mid-1970s for use in Systems Network Architecture (SNA) environments. SDLC is unique in that it was the first synchronous, link layer, bit-oriented protocol. The ISO modified SDLC to create the High- Level Data Link Control (HDLC) protocol and release it as a standard. Answer B is incorrect because ISDN is an end-to-end telephone service that is digital in nature. Answer C is incorrect because Link Access Procedure–Balanced (LAP-B) is a subset of HDLC and is not used by SNA. Answer D is incorrect because X.25 is an efficient protocol developed in the 1970s for packet-switched networks..

Where are chaperones found? periplasm, cytoplasm, or cell membrane (can be any combination of those) Solution Chaperones are found in all types of cells and in most of the cell organelles. They are found in both periplasm and cytoplasm as the chaperones are involved in proper folding of protein molecules, once they are translated. There are some chaperones which are also found in extracellular spaces. These chaperones are involved in functional folding of those protein molecules which are to be released extracellularly..

Talks about McDonaldization What do you think of this concept? Do you see a standardization of the world around us? What do you like and dislike about the standardization of society? Solution McDonaldization is the process of rationalization, albiet taken to extreme levels Rationalization is a sociological term that simply means the substitution of logically consistent rules for traditional (or illogical) rules One of the fundamental aspects of McDonaldization is that almost any task can (and should) be rationalized example: the premise of fast food often turns out to be just the opposite - long waits in lines. Fast food is not necessarily good food - in fact, McDonald\'s food is extremely unhealthy and the taste is average and bland. The system of efficiently producing and distributing their food has some other consequences, namely millions of tons of trash each year (disposability) and a food cultivation system of questionable ethics the four main dimensions of McDonaldization are: Dislike of standardization---- 1. Irrationality of Rationality 2.De-McDonaldization 3.cultural hybridization.

Question 6 A wastewater sample was collected after screening and grit removal step from Waterloo WWTP. The sample was analyzed in the lab. The sample was found to have the following properties: Total COD 350 mg/L Soluble COD 200 mg/L BOD, 220 mg/L VSS/TSS ratio is 0.7 Removal efficiency of the primary clarifier in the WWTP is 60% for both VSS (both nbVSS and bVSS) and FSS. Assume that biological activity is restricted in primary clarifier, and all soluble compounds pass through. The effluent from primary clarifier is further treated in active sludge Solution To calculate rb COD we use formula sCOD = rbCOD + nbsCOD Where sCOD is soluble COD = 200mg/L, so rb COD 200 = rbCOD + 50; rbCOD = 150 mg/L Now for calculating sb COD we use formula bCOD = rbCOD + sbCOD However, we don’t have bCOD [Biodegradable COD], to calculate that we use bCOD (1.7) of (BOD) bCOD = 1.6 x 220 = 352 mg/L Now bCOD = rbCOD + sbCOD 352 = 150 +sbCOD; sbCOD = 352-150 = 198 mg/L.

Alighting time p time per passenger 3 seconds. Compute the dwell time at each stop and the total dwell time. Assume the clearance ime 5 seconds. Briefly describe the four categories of transit system characteristics. c. Briefly describe the various transit modes of transportation End of Problem #4 Problemi #5 (20 points) Transportation Engineering is a multidisciplinary area of study. It is a profession that carries distinct societal responsibilities. What would a comprehensive training include? Provide examples of each training tem a) b) c) d) Explain the difference between direct elasticity and cross elasticity. Give one example of each What does CBD mean? Give an example of a CBD A transportation network having the following characteristics Travel time (minutes) between nodes Nodes From 10 10 10 0 16 12 Each node represents an activity center, and each link represents travel time in minutes. Draw a link/node diagrams for the travel times and distances, if the average travel speed on all links is 30 miles per hour End of Problem #5 Solution 4. (a). There are 2 ways in general to model the dwell time at a particular stop which depends on whether the boarding and alighting processes are sequential or simultaneous. Assuming in the question given that sequential boarding and alighting takes place since only one front door is available for flow of passengers: Dw = a * A + b*B + td ; where A and B are the number of boarding and alighting passengers respectively a and b are time intervals for boarding and alighting per passenger. td is the average clearance time for opening and closing the doors. Here a= 3 sec, b=1.8sec Therefore, at Stop 1: Dw1 = 3*20 + 1.8*0 + 5 = 65 sec Stop 2: Dw2 = 3*5 + 1.8*3 + 5 = 25.4 sec Stop 3: Dw3 = 3*7 + 1.8*5 + 5 = 35 sec Stop 4: Dw4 = 3*3 + 1.8*6 + 5 = 24.8 sec Stop 5: Dw5 = 3*4 + 1.8*8 + 5 = 31.4 sec Stop 6: Dw6 = 3*2 + 1.8*7 + 5 = 23.6 sec Stop 7: Dw7 = 3*0 + 1.8*12 + 5 = 26.6 sec Total dwell time= 231.8 seconds (b). Transit system characteristics can be classified into four main categories: i. System performance elements: Contains entire set of physical performance related elements which decides the raw efficiency of the central system employed as the primary functional core unit of the transit model. This includes Service frequency, operating speed, reliability and safety measures and line and productive capacities. ii. Level of Service (LOS) is an important service parameter that affects the users drastically due to differential change in its delivery. It is a simple basic most powerful characteristic that can attract the users or provide bad experiences to them if miniscule error occurs in provider’s implementation. The factors that affect LOS are performance.

As your reward for saving the Kingdom of Bigfunnia from the evil monster “Exponential Asymptotic,” the king has given you the opportunity to earn a big reward. Behind the castle there is a maze, and along each corridor of the maze there is a bag of gold coins. The amount of gold in each bag varies. You will be given the opportunity to walk through the maze, picking up bags of gold. You may enter only through the door marked “ENTER” and exit through the door marked “EXIT.” (These are distinct doors.) While in the maze you may not retrace your steps. Each corridor of the maze has an arrow painted on the wall. You may only go down the corridor in the direction of the arrow. There is no way to traverse a “loop” in the maze. You will receive a map of the maze, including the amount of gold in and the direction of each corridor. Describe and analyze an efficient algorithm to help you pick up the most gold in this maze while traversing a path from the start to the finish.

Answer the following questions about molecule movement across a membrane. a. How is osmosis similar to simple diffusion of CO_2 across a membrane? How is it different? If an aquaporin is involved, how does this change your answer? b. Compare and contrast carrier proteins and channel proteins. Include information about both structure and mechanism of transport. c. Compare and contrast indirect and direct active transport. Give a specific example for each type of transport. Solution 5a: Osmosis is the movement of water molecules down the concentration gradiant through a semipermeable membrane. Both osmosis and simple diffusion of CO2 across a membrane occur down the concentration gradiant and are passive transport. However, osmosis transports hydrophilic water molecules while simple diffusion transports hydrophobic non polar CO2 molecules. If an aquaporin is involved, the proces would be called as facililated diffusion which refers to transport of polar, charged, hydrophilic molecules down the concentration gradiant with the help of membrane transport proteins. 5b: Carrier proteins are the transporter proteins that are actually the integral membrane proteins serving in transport of ions across the membrane. These proteins have ion binding sites and exhibit changes in shape to transport the ions. Channel proteins are the integral membrane proteins that form the hydrophilic channels for transport of polar, charged and hydrophilic substances across the membrane. They do not undergo the shape change. 5c: Direct active transport couples the exergonic chemical reaction for increasing the solute/ion concentration on one side of the membrane. The indirect active transport includes coupling of favorable downhill movement of one solute to the unfavorable uphill movement of other substance. For ex: sodium potassium pump couples ATP hydrolysis with uphill movement of sodium (direct active transport). Downhill movement of sodium coupled with uphill movement of glucose (indirect active transport)..
