In 2017, the first baby was born in the U.S. to a mother who had received a uterus transplant,
meaning a uterus donated by another human female was implanted into the mother and this
a transplanted uterus was the site of implantation, and development of the fetus to term. Obviously, this type of medical procedure is not without challenges and risks. Briefly describe three possible challenges of uterus transplantation (anywhere from initial surgery to childbirth) - one challenge must relate to the immune system, one challenge must relate to the reproductive system, and one challenge must relate to development. Your answers do not necessarily need to be medically perfect (none of us have medical degrees, yet) but they should reflect your understanding of the three systems, supported by details of the structures and processes that might be involved in the challenges you identify.

I have been given a project to do that will have the potential of being implemented. The scope of the project is to come up with a remote monitoring system for the status of a pump-motor arrangement which has a valve in front of it that also had to be monitored. The level of the water in the tank where the pump is pumping has to be monitored by the use of float switches. This all has to be with the aid of instruments like flow switches, float switches and other instruments through a microprocessor and a controller and has to be taken to an Human Machine Interface.
Please help me come up with how you can intergate an Arduino controller to monitor the status of the Physical Plant remotely. Please explain briefly and show stages theorticaly how this project would work and provide me with a sketch. Thank you

Mr. Tan Eng Lee’s property development company, Alan Construction Private is involved in numerous property development projects in Malaysia. He thinks that the current functional based organizational structure is not working well. Alan Construction private is involved in a condominium project in AUSTRALIA, a housing project in ENGLAND, a shopping mall project in AMERICA and a business center project in AFRICA.
He called for a meeting with the heads of department for Human Resource, Administration and Finance , ICT, Warehouse and Procurement and Engineering to discuss how best to re-structure their organization and to discuss the advantages and disadvantages of the new structure.
(a) Based on the information provided above, recommend a suitable
form of organization structure that would benefit Alan Construction
Private. (You need to provide a drawing of the structure).
(b) What are the advantages and disadvantages of the new structure? (10marks)

What exactly does it mean when a plant has a scientific name that specifies a vairety, for example Nothofagus solandri var. cliffortioides, or when the name includes an "x", as in Populus maximowiczii Henry x trichocarpa, Populus xcanadensis, or "Crataegus x macrocarpa"?
All of these species are in the USDA Plants database (of plants that occur in the US). There are > 6000 occurences of the string " var. " ~500 occurances of " ssp. " and only a handful occurences of " x " in the database,

Autonomous driving technology is going on a test run on actual roads in order to become commercialization. As self-driving technology, which has been conducted under controlled experimental conditions, is going to drive on actual roads, it is facing various problems in reality. Self-driving cars, which are being developed at home and abroad, are considered to be much safer than cars driven by humans, but are not yet perfect. Will these cars be able to commercialize only after they have solved all of the various problems they face in the actual driving of the road, or will they be able to be more efficient and safer than human driving vehicles? Explain your opinion about autonomous driving technology with above question and What level of accidents and mistakes can we tolerate in self-driving cars.

The biological activity of some organs can be investigated using radioactive isotopes. For example, iodine is important in the action of the thyroid. A subject is injected with a small amount of radioactive 131 I and after a few days, the following measurements are made with a Geiger counter:
1.) The counter is placed in contact with the abdomen and 2750 counts/s are observed six days later, the counter records 600 counts/s?
2.) With the counter over the thyroid, 5,500 counts/s are observed and six days later 3290 counts/s are observed?
a) If the physical half life of 131 I is 194 hr, what is the biological half life of iodine in the bulk of the human body?
b) What can you say about iodine in the thyroid?
The answer is supossed to be 100 hrs.

A sugar cube (sucrose) weighs about 3 g. A 20 oz. (591 mL) container of Gatorade (or Powerade) contains 35 g of sucrose (table sugar). 1.0 oz. = 28.35 g. Sucrose is a dissaccharide consisting of glucose and fructose (a 1:1 ratio). Gram molecular weight (GMW) of sucrose = 342.2 g/mole. When ingested, sucrose is rapidly broken down into glucose and fructose by enzymes in your body. In humans, normal blood glucose levels are maintained at about 0.005 moles/L (which = 5.0 milllimoles/L, or 5.0 mM). Assume that your total blood volume is 5 L (average human). You drink a 20 oz. container of Gatorade. What is the molarity of glucose in your blood after drinking the Gatorade?
