Suppose you discover a novel process in a little-studied cell type in which application of a chemical causes an unknown organelle to undergo energy-dependent movement from near the MTOC to the plasma membrane. To probe the cytoskeletal elements required for this movement you add an actin depolymerizing drug latrunculin A. This drug does not affect the initial movement of the organelle away from the MTOC, however the organelle stops before reaching the plasma membrane. You next try the microtubule depolymerizing drug colchicine. This drug prevents any movement of the organelle away from the MTOC in response the chemical stimulus.

1. What do these results tell you about the identity of the cytoskeletal elements involved and the identity of the required motor proteins over the course of movement?

2. Predict the result you would get if you added both latrunculin A and colchicine at the same time. Would the resulting phenotype be a combination of adding each drug alone, would one or the other drug’s effects predominate, or would they cancel each other out? Why?

The Social Security system is financed by taxes on the wage and salary incomes and the profit incomes of self-employed persons who are currently working and paying into the system. These individuals pay Social Security tax of 6.2 percent on incomes up to roughly $132,900 with a matching payment by their employers. Income above $132,900 is not subject to tax. Benefits are determined by how much a worker paid into the system over his/her working life. Thus the more one pays into the system the higher are the retirement benefits. The system was devised as a program that would provide a minimum retirement income to working persons. It was to be similar to a pension program.

Economic analysts are anticipating Social Security to run out of funds near the year 2036. There are many proposals for reforming Social Security, but only one fundamentally alters the nature of the current system: privatization.

For Critical Analysis:
Is the Social Security tax progressive, regressive, or proportional? Are Social Security transfer payments designed to redistribute income from upper to lower income retirees? What would happen if Social Security were privatized?

4. For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; use each word or phrase only once.

Microtubules are formed from the tubulin heterodimer, which is composed of the nucleotide-binding __________________ protein and the __________________ protein. Tubulin dimers are stacked together into protofilaments; __________________ parallel protofilaments form the tubelike structure of a microtubule. __________________ rings are important for microtubule nucleation and are found in the __________________ , which is usually found near the cell’s nucleus in cells that are not undergoing mitosis. A microtubule that is quickly growing will have a __________________ cap that helps prevent the loss of subunits from its growing end. _____ microtubules are used in cilia and flagella; these microtubules are nucleated from a __________________ and involve a “__________________ plus two” array of microtubules. The motor protein __________________ generates the bending motion in cilia; the lack of this protein can cause Kartagener’s syndrome in humans.

Topic: Evaluate the performance of Chinese Feng Yun (FY) satellites for both series (i.e., polar-orbiting sun-synchronous, FY-1 & FY-3) and (geosynchronous, FY-2 and FY-4). Your discussions should include the followings: i. name of series (e.g., FY-1 C, FY-2A, FY-3b, or FY-4A) ii. mission type (weather observation, land observation, marine/ocean observation, or communication) iii. orbit type (geostationary/geosynchronous, polar orbiting or near-polar Sun-synchronous) iv. orbit height/altitude (if elliptical orbit, then Apogee and Perigee altitudes)
v. inclination vi. launch date and status (operational or decommissioned) vii. resolutions (spatial, spectral, radiometric, and temporal) viii. name of sensor (s) ix. method of scanning (along track or across track) x. swath width xi. orbital period, and xii. orbital cycle, etc.

A 35-year-old African American woman36 weeks gestation, gravida 2, para 1100, delivered a 7-pound baby boy 4 hours ago with Apgar scores 7 and 9 at 1 minute and 5 minutes, respectively. The nurse entered the postpartum room and noted that the baby was near the cold window, which was directly under the air-conditioning vent. The nurse suggests to the mother to place the baby in a different part of the room. The mother tells the nurse that she is concerned about her baby. The mother requests that her baby not go back to the nursery because she noticed a bruise on her infant’s bottom and some bloody discharge in her baby’s diaper when she changed the diaper 30 minutes ago. (Learning Objectives 2, 8)

Based on the information above, answer the following questions:

1. Can you explain the newborn’s assessment to the mother regarding any potential abnormalities? What advice would you provide to this new mother?
2. Why did the nurse suggest placing the baby in a different part of the room?

1. You are a nurse working in a labor and delivery unit in a small town near a Native American reservation. Charity, your patient, is about to give birth to her sixth child. Her family does not have health insurance. Normally she would give birth at home; however, her blood pressure is high. Her family is doing a dance to scare away the evil spirits that brought about this medical condition. She is in a lot of pain but refuses an epidural. She believes that pain is something that should be tolerated. There are also about 20 family members present to watch the birth, including all of her children. After the baby is born, she hand-expresses colostrum from her breasts and disposes of it. Additional family members arrive with all sorts of food to celebrate the birth of the baby. (Learning Objectives 5 and 6)

A. What are the cultural traits with Charity and her baby that are specific to her Native American culture?

B. How would you provide culturally sensitive nursing care to Charity and her baby?

Use MATLAB to create a script which solves for problem 5.9 in the book (5.11 in the 4th edition). Given are the equations for the moment, as a function of x, starting from the leftmost side of the beam with x=0 and ending at the other end of the beam with x=12. This piecewise function together makes up the moment equation for the beam given. 0 ≤ ? ≤ 3 ?(?) = 265? − 5.56?³ , 3 < ? ≤ 6 ?(?) = −50?² + 415? − 150, 6 < ? ≤ 10 ?(?) = −185? + 1650, 10 < ? ≤ 12 ?(?) = 100? − 1200 Use if-else statements to determine the f(x) value for each value of x (lower bound, upper bound, and the guess for the root) to use in the bisection method. Also, use a while loop to iterate until the approximate relative error is below the stopping criterion, es=0.05%. Finally, plot piecewise function and verify that the root found is at or near the point on the beam in which the moment is zero. Create appropriate labels (xaxis, y-axis, and title). Here's what should happen when the script is run:
