Hello, I am looking for someone to write an article on The Responsibility of Being an Educator. It needs to be at least 250 words. My research is in two areas: how education policy is used in school and its impact on teachers, and also professional education and how teachers, social workers, and nurses collaborate together for the benefit of students.

I do support the teacher’s union because I think that teachers form an important aspect of our society that needs to have representation. Teachers are responsible for training the leaders of tomorrow, so they should receive all the help they can get.

My advice is to get involved as much as you possibly can. Go out and talk to people, actively participate in extra-curricular activities, and enjoy your time here because it sure goes by fast. Don’t look back in twenty years and regret all of the missed opportunities you had in college because you will almost certainly never forgive yourself.

Provide a 2 pages analysis while answering the following question: Air legislation. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. Abdullah Alshafi 4 May Effect of Centre Of Gravity On The Aircraft: Take-off , Landing And Cruise

Center of gravity (cg) is a point inside or outside a body through which the whole weight of the body appears to be acting. For an aircraft, the center of gravity position depends on, and is controlled by balancing the overall size and mass distribution characteristics including the effect produced as a result of the consumption of fuel. Center of gravity calculations are of critical importance during aircraft design.

Figure 1. Weight distribution due to different components of an aircraft.

For stability of the aircraft during take- off, landing and cruise , the center of gravity of the aircraft must fall within the limits and range specified for a particular type and make of an aircraft as established by the manufacturer.

The aircraft is capable of rotation along the three axes namely. Pitch ,Roll and Yaw, in addition to a linear motion along the specific air route when in- flight. For any type of movement shown by the aircraft ,the weight of the aircraft must be balanced out to maintain the position of the center of gravity for stability.

An air craft can have Lateral center of gravity, Longitudinal center of gravity and even Vertical center of gravity. The most important if these being the Lateral cg, which has a critical role in stabilizing the pitch of the aircraft. Lateral cg is further partitioned into Forward and Aft cg. There are limits to the Fore and Aft cg positioning. If the Fore and Aft cg is out of range the aircraft may pitch uncontrollably up or down during take-off ,flight or landing. For example if the cg is too far forward , the plane is likely to tilt forward or crash

upon take-off.

Figure 1. Effect of shift in Longitudinal cg on the pitch of an aircraft.

The Lateral cg position is to be maintained in order to control and stabilize any unwanted roll movement during any stage of flight. The position of Lateral cg can shift if there is an uneven distribution of fuel in the tanks,or in case of an uneven seating arrangement of passengers in a small aircraft.

Figure 3 Effect of shift in Lateral cg on the Roll of an aircraft during flight.

The Vertical cg position is associated with the stability of the flight along the yaw axis. A shift in the vertical cg can result in yawing motion if not compensated for by the pilot during take-off, flight and landing.

The vertical cg position may be shifted even due to cross winds. This results in a sidewise motion of the aircraft during flight.

Figure 4.Effect of change in Vertical cg on the yaw of an aircraft.

The change in the Vertical cg of the aircraft can disturb the course during flight.During landing the aircraft can experience problems due to the sidewise movement and may miss the landing.

The center of gravity is a major factor in the stability of an aircraft in all the phases of flight . take-off ,cruise / flight and landing. A disturbance in the longitudinal, lateral or vertical cg can upset the movement of the aircraft along either of the three axes .pitch , roll or yaw.

Hi, need to submit a 1000 words paper on the topic O2 transfere in human buddy. Chemical engineering treats circularly system as a chemical process that involves the heart as a pump while the blood vessels act as passageways for oxygen. Generally, chemical engineering uses mathematical equation to show a complete oxygen transportation process in the body. Moreover, chemical engineering involves two basic terms including convection and diffusion that helps in calculating oxygen transport in the human body. Convection is more common in the large blood vessels like arteries while diffusion is more likely to occur in the small blood vessels such as capillaries and veins.

The two main mathematical equations involved in determining oxygen transport are the overall flux that describes oxygen flow via pipes and Fick’s law that explains diffusion of fluid along a concentration gradient.

Oxygen moves in the human body in the breathing process through nose and mouth then goes via the lungs and dissolves in the water lining of alveoli. Oxygen then sticks to red blood cells while passing through the alveoli capillaries.

Circulatory system plays a significant role in transporting various materials in the human body. Circulatory system ensures that nutrients, water and oxygen are transported to the body cells while transporting waste products produced by body cells such as carbon dioxide away from the body. The circulatory system acts as a highway with network throughout the human body and it involves the heart, and the blood vessel. The heart is responsible in pumping blood and maintaining blood flow in the whole of the body system while the blood vessels transport blood away from the heart to other parts of the blood. The whole of the circulatory system transports oxygen from outside the body into the blood stream and carries away waste from the blood cell, carbon dioxide to the outer part of the body.
