Green Energy Relаy – A Jоurney Tоwаrd Chаnge Tо raise awareness for renewable energy and sustainable living, a team of passionate eco-activists is preparing to embark on a cross-state relay run. Their journey begins in City 1, where the opening ceremony takes place, and concludes in City 10, the state capital, where a rally is scheduled to draw media attention. Each team member will run a portion of the route, passing a symbolic “green torch” from city to city. The transportation network between cities is complex. Roads are not always accessible in both directions, and the terrain varies, impacting distances between cities. The available routes and the mileage between each pair of connected cities are shown in the network diagram below. In this diagram, cities are represented by numbered circles, and arrows represent roads. A single-headed arrow indicates a one-way road, meaning the team can only travel in the direction of the arrow. A double-headed arrow indicates a bi-directional road, meaning the team can run in either direction, and the mileage is the same both ways. Distances are indicated by the numbers shown next to each arc and are measured in miles. The goal is to plan the most efficient path for the team. Since their mission is time-sensitive and physically demanding, they aim to minimize the total distance traveled while successfully reaching their destination. Question - Under the current conditions: What is the minimum total distance the team must travel to get from City 1 to City 10? [org_dist] miles What is the best route for the team to take? (For example: 1, 2, 3, 4, 10) [org_path] However, midway through planning, the team receives an exciting update: a well-known politician, who strongly supports their cause, is visiting City 5. Meeting this figure could generate significant public and media attention. Now, they must decide how to adjust their route to include a stop in City 5—without significantly extending the journey. What is the minimum total distance they must travel while ensuring a visit to City 5? [rev_dist] miles What is the best route they should take that includes a stop in City 5? (For example: 1, 2, 3, 4, 10) [rev_path]
The Gоurmet Grаnоlа Prоduction Problem Bаckground:Healthy Bites Co. produces two popular granola products: Tropical Crunch and Mountain Mix. Both are premium, nutritious snacks made from high-quality ingredients, and both contribute strongly to the company’s brand and revenue. Tropical Crunch is a fruit-forward blend rich in dried mango, pineapple, and coconut.Mountain Mix is a hearty, nut-based granola with almonds, seeds, and cranberries. Production Requirements (per batch): Resource Tropical Crunch Mountain Mix Oven Time (minutes) 20 60 Mixing Labor (hours) 2 2 Packaging Material (units) 3 1 Available Weekly Resources: Oven Time: 1,200 minutes Mixing Labor: 120 hours Packaging Material: 160 units Profit per Batch: Tropical Crunch: $70 Mountain Mix: $75 Challenge for the Operations Team: The company wants to maximize weekly profit, but it must stay within its current resource limitations. Since both products are highly valued in the market—one is fruit-based and the other nut-based—the team is not allowed to eliminate either product from the production plan. You must determine the optimal number of batches of each product to produce in order to maximize profit, using all available data. Questions: What is the maximum weekly profit the company can achieve under the current resource constraints? $[profit] A packaging material vendor offers to sell additional units at a price of $15 per unit. How many units of packaging material should the company purchase, if any, to maximize profit? [addpackage] units Due to a quality issue, the profit from Tropical Crunch drops significantly, prompting the company to stop producing it. Under this condition, what is the highest unit profit value for Tropical Crunch that would still justify producing only Mountain Mix? In other words, determine the maximum value of such that Tropical Crunch becomes non-optimal when its unit profit falls below (Suppose the company decides not to purchase any additional packaging material.) [minimum]

There аre FIVE questiоns frоm which yоu аre required to аnswer only THREE; any additional answers will not be marked. All questions are weighted equally, and worth a maximum of 100% each. There are 3 answer boxes below this box. Each answer box MUST be used to answer one of the questions you select. Please also remember to tell us which question you are answering. See the example below: 'This is my answer to Question 1...' Questions are as followed: Question 1 Answer both parts of this question: a) Describe the range of bacterial mechanisms of resistance against β-lactam antibiotics and explain in detail the activity and classification of the β-lactamase enzymes, using named examples. (70%) b) Discuss potential solutions to the clinical problems posed by β-lactamases and explain key limitations of these solutions. (30%) Question 2 Discuss the features of a successful gastrointestinal pathogen, using a named example. Explain how it uses its pathogenicity factors to survive passage through the stomach and infect the gut epithelium in the face of host defence mechanisms. (100%) Question 3 Answer both parts of this question: a) Discuss urinary tract infections (UTIs), including aetiology and host defence mechanisms. Using a named example of a significant bacterial UTI pathogen, describe the relevant pathogenicity factors. (70%) b) Discuss the methods that can be employed for laboratory diagnosis of a urinary tract infection. (30%) Question 4 Discuss the transmission (20%), symptoms (30%), diagnosis (25%) and treatment (25%) of acute and chronic hepatitis B virus (HBV) infection. Question 5 Discuss the use of molecular methods in diagnostic microbiology and typing. Your answer should consider methods based on mass spectrometry and nucleic acid amplification, but not nucleic acid sequencing. (100%)
