Neuron Function

Neurons are cells that send information to the brain. They are a made up of the cell body, dendrites and axons. Dendrites allow a message to go to the cell body, and Axons, conduct the message away from the cell body.

There are three types of neurons: Inter neuron (As shown below), motor-neuron, sensory-neuron

The neurons communication method is called Action Potential. It is an electrochemical signal that comes from a nerve impulse.  It starts with an electrical change that moves from the cell body, through the axon. The movement is caused by a positive ions causing a chain reaction throughout the axons.  This is called Depolarization. It is an message that stimulates the axon when sodium ions flow into the axon and changes the axon segment to negative. Then flowing through the axon with it action potential. After the axon re polarizes  with channels let the K+ ions to leave the axon, then the charge returns to its original charge.

Synapse:

A synapse has, the ends of dendrites receiving the neuron, tips of terminal branches of axon and a synaptic gap, or a tiny gap between neurons.

An Axon terminal button produces Neurotransmitter, it keeps NT in the synaptic vesicles, and recycle NT. When Action Potential reaches the end of the axon, is causes the vesicles to give away the neurotransmitters through the synaptic gap and reaches the receptors on the receiving neuron.

After receiving the neuron the dendrite determines the NT function as either excitatory, or inhibitory. Excitatory, stimulates the AP on the receiving neuron and inhibitory represses AP.

Beatty’s Lecture

Question: What reasons does Beatty give for the current state of society and for books being destroyed?

Captain Beatty has multiple reasonings for his beliefs in burning the books in their dystopian society. First, books are knowledge and to the government knowledge to the people is dangerous. All the books should be burned to not let the public obtain that knowledge. Secondly, Beatty told Montag, “If you don’t want a man unhappy political, don’t give him two sides to a question to worry him; give him one. Better yet, give him none.” (Pg.58). This shows that the government is making everything boil down to one simple answer. Not letting people question their society and not making their own opinions. Thirdly, an example of his reasonings is so the books not to offend anyone. He makes the point where if there is a book that offends someone or a person, burn it so everyone can be happy. “Colored people don’t like Little Black Sambo. Burn it. White people don’t feel good about Uncle Tom’s Cabin. Burn it.” (Pg.57). But where there is nothing to offend anyone how can anyone be truly happy. In life you need something to fight for, something to believe in and with the burning of the books how can this happen. Also, without being sad or hurt, how can you be happy. Captain Beatty said, “Fire is bright, fire is clean.” (Pg.58). Beatty explains his reasonings furthermore explaining that what the firemen are doing is the right thing and the burning of the books is the only way everyone can be happy at once. Although through Montag’s point of view, that’s not the case.

Arts and Sciences

Arts and Science is very hard to compare but, both are very important to our society. Without Science where would we be in the world, what medical or architectural achievements would we have accomplished without it. But when we do accomplish those things, we need a way to preserve it. Arts and writing can show how things were done. To show the past, the rights and wrongs to make sure history does not repeat its self in a negative way. Also science helped structure our world today in buildings, medicine, and technology.  To help us survive in the world. But can all this exist with art. Creativity must be the base line of the architectural designs of our world. With everything that we create, there must be creativity right next to it. Art is creativity and without expressing emotion and our thoughts through it how are we suppose to have science and intellectual design. One cannot live without another.

Solar Oven Project

Science solar oven

Steps:

  1. Cut a flap on the top part of a pizza box
  2. Cover the inside of the flap with Aluminum foil
  3. Use clear plastic wrap to trap heat inside the box
  4. Put black construction paper on the bottom
  5. To insulate wrap Styrofoam in aluminum and then place around the inside of the box.
  6. Use a ruler to prop up the flap to collect sunlight and heat.

Materials

Cardboard box and flap

Aluminum foil

Clear plastic wrap

Black construction paper

Newspaper

Styrofoam

 

Research: Three common types of solar cookers

Box cooker: They are a box with an air tight wrap around it, while having a clear plastic wrap on the top allowing heat to come through but not leave, heating up the box to high temperatures.

Pro: Traps heat inside well, easy to make, can reach 150 degree Celsius, air tight and sealed well, not having to readjust.

Con: Cannot reach higher than around 150 degrees Celsius.

 

Panel cooker: Similar to the box cooker but has three sides to it directing the heat towards the food inside the box.

Pro: easy to make, better for moisture foods, does not require alignment, difficult to burn or over cook.

Con: 100 degrees Celsius, slow cooker,

 

Parabolic Cookers: They are shaped like satellite dishes with a pot centralized I the middle of the dish and reflective surfaces on the satellite dishes. This allows for the sun rays to hit the satellite and reflect the sun rays onto the food.

Pro: able to cook higher temperature foods, can reach higher temperatures than other cookers, cooking quickly.

Con: need to adjust the cooker a lot having to be facing the sun, difficult to build

 

We are choosing the Solar Box Oven because it can reach high temperatures and trap heat well.

How thermal transfers:

In this case with the solar oven the type of thermal energy is radiation. The suns UV lights travel through space to earth and hits the solar oven. The suns rays travel in waves instead of direct contact like other types of heat transfer and does not need any form of contact to heat up the box. The waves can travel through the clear plastic  but cannot escape.

Design

Here is our Solar Box Oven

 

 

This is our box that we started with

We cut open the box and wrapped clear plastic around the open flap to allow light and heat to be trapped in the box

Then we put Styrofoam wrapped in aluminum foil to reflect the heat towards the food

This is the finished project with the aluminum flap catching the sunlight and heat and reflecting in into the box

Then a picture of the food on an aluminum plate with the sun hitting the plastic wrap trapping the heat inside to cook the marshmallows, crackers, and chocolate.

Experiment

We had three trials each of the same food, marshmallow, chocolate, and a gram cracker, the first took 15 minutes, second took 20 minutes, and the third 25 minutes.

The first one tasted, a little cooked but still uncooked. The food was warm and chocolate melted

The second trial was tasted more crisp but uncooked on the inside.

The third trial that lasted 25 minutes the marshmallows and cracker were both crispy and very hot, the chocolate melted and turned to a liquid.

 

Reflect

We redesigned the oven to have more panels to reflect the heat and sun lights rays into the box. This improves the heat and temperature of the box because it covers more of the heat possible exit points. Also the main reason because it reflects and directs the heat into the box cooking the food from more sides and in a hotter oven.

Canadian Mulitculturism

https://bc.ctvnews.ca/accused-in-racist-skytrain-attack-now-charged-with-sexual-assault-1.3718509https://bc.ctvnews.ca/accused-in-racist-skytrain-attack-now-charged-with-sexual-assault-1.3718509

This article is from CTV news and shows negative side of Canada’s multiculturist.  A man attack a women who was wearing a hijab and ripped it off her. This shows the negative part of Canada and the parts that pop up that still astonish the

countryhttps://www.indiansummerfest.ca/

This is a festival in Vancouver that shows that people want to and are able to celebrate their culture and also show off their pride in what they believe in, and what their heritage is.

 

I do think Canada is a multicultural country because we allow and accept all walks of life. Even if there are bad and racist things the good out ways the bad.
