p= 400e^(-20x) p is price and x is thousands (thats all the infoi have)

find R(x)

Find quanitity and price to maximize revenue

(a) P= nRT / V-nb

(b) P= (nRT / V-nb) - a*n^2 / T^1/2 * V(V+nb)

Please show steps.

There is a string: cabcedeacadeddaaaba. Use Hoffman coding to draw the coding process and write the code of each character

Protein X, a protein of the electron transport chain in the inner mitochondrial membrane, can be removed from cell debris by extraction with salt solution. In contrast, protein Y from the same source can be removed only by extraction into detergent solutions or organic solvents. What kind of membrane proteins are protein X and protein Y? Explain.

Which detergent would be best suited for the membrane extraction or refolding for each of the integral membrane proteins in
the following list? For each of the integral membrane proteins listed, would you choose to extract or refold and why?
1. LamB
2. Complex I (ETC)
3. LacY
4. OmpC
5. ABC transporter
6. GPCR      

MsbA is an ABC transporter that transports LPS from the cytoplasmic to periplasmic leaflet of the inner membrane of E. coli (flipase).

A) Diagram the basic mechanism how this ABC transporter would transport LPS across the membrane.

B) You have isolated a variant of MsbA that has the Q-loop mutated from a Q to a V. How do you think this will affect the function of MsbA?
Design a set of experiments to test your hypothesis and explain what you expect to observe.

Project Description

GTM systems is a large IT company with offices all around the world. The company delivers software products and services to corporate clients. One of the reasons for its enduring success and consistent performance over the years is the ability to leverage technology and find innovative applications for it.

SmartWeather

With climate change increasing the unpredictability of local weather conditions, there has been great demand for technology that can provide reliable weather information. Weather conditions impact several organizations and businesses – ranging from agriculture, outdoor event management, hospitality, travel and tourism, and healthcare.

While GTM has no expertise in meteorology, it proposes to aggregate weather data from multiple providers and use analytics to correlate it with meaningful conclusions for businesses.

Example use cases could be generating forecasts based on local weather conditions around:

1. Consumption of hot versus cold beverages depending on cold, sunny, or rainy weather
2. Number of visitors to a tourist site or an open-air entertainment event
3. Likelihood of seasonal illnesses such as flu in particular locations

The main system will comprise a web portal and a set of “apps” available on the popular mobile operating systems. Apart from this, clients can ask for specific services or apps based on the insights that the analytics can generate.

Backlog for the main portal

Work items Enable registration for free and paid users Build integrations with public weather services around the world Detect locations based on GPS (if on a device) or IP Create a schema and a database for storing weather data based on location Build logic to reconcile and aggregate data from multiple service providers Access control for paid services Provide severe weather advisory to registered users on the portal Have provisions for advertisements on the portal and apps Show current weather at a location Show forecasts for five, ten, and fifteen days at a location Provide seasonal forecasts like seasonal precipitation and temperatures Show satellite images Show time-lapse videos of satellite forecasts Make a responsive design for the portal (usable for different devices and form factors) Publish API or Services for client apps Create apps for iOS and Android phones

Project task

Based on the above scenario, you are expected to perform the following tasks.

1. Identify at least five epics and 15 user stories from the case above(use your interpretation and independent research). Link the stories to the epics.
2. Get a free JIRA account and create a Scrum project.
3. Enter the backlog (epics, stories and subtasks) in JIRA.
4. Make a tentative release plan, by assigning the stories to three sprints.
5. Start and complete one sprint.
6. Submit screenshots of: Epics, Backlog,release plan, and Scrum board with tasks in various states.

The unit eludes to the fact that a photographer’s workflow separates the amateurs from the novices. Provide an example of two workflows: one that would likely suggest the person using it is a more-experienced amateur photographer and one that would likely suggest it is one used by a less-experienced novice photographer. Provide brief explanations for both and why each is fitted for each type of photographer.

The PMIS system is one of the leanest systems around, but it is far from agile in terms of responding to new requirements’.

Critically explore and evaluate this statement in relation to lean and agile methodologies. You should include academic literature and examples within your answers.

The success of any project is dependent on a diverse range of skills, abilities and competencies of the project manager which should both inspire the project team to succeed and win the confidence of the customer. Comment on this statement by describing the competencies required of a project manager.

Paula and Dan were in a car accident. Paula sues Dan for negligence in the proper federal court. After the close of discovery, Paula brings a motion for summary judgment (MSJ) and Dan files an opposition. In support of her motion, Paula provides affidavits from ten eye witnesses to the car accident, all of whom state under oath that they saw Dan run a red light, which caused the car accident. Dan provides one affidavit from his wife, the passenger in his car who had drunk three glasses of wine an hour earlier, who states under oath that the light was green and Dan did not run a red light. Which of the following is correct?

Select one:

a. Because there is a disputed fact, the case must proceed to trial.

b. Because Paula has ten eye-witnesses and Dan only has one, Paula’s MSJ should be granted.

c. Dan’s one eye-witness is his wife, who might lie for her husband, and who also may have been intoxicated at the relevant time; therefore, the wife’s testimony should be disregarded as unreliable and Paula’s MSJ should be granted.

d. Both B and C

1. Which of the following bonds are the most polar, that is, have the greatest ionic character: H-Br, N-H, N-O, P-Cl? Why?
   
   
2. Write the Lewis symbols expected for Sn, Br- and S2-.
3. Predict the molecular geometry of nitrogen trichloride.
   
   
4. Nitrous oxide, N2O, is the familiar laughing gas used as an anesthetic in dentistry. Predict the shape of the N2O molecule.
5. Only one of the following molecules is polar. Which is it, and why? SF6, H2O2, C2H4?
