How Human Computer Interactions Incorporated Into Computer...
2. Purpose
The purpose of the authors is to introduce the capabilities of context–aware design and give an insight into how
it can positively affect and benefit the user's lifestyle. The authors inform the audience of the three types of
context–aware computer systems and uses prototype examples to clearly explain them to an audience who
would not be knowledgeable about this field. The article highlights how human–computer interactions
incorporated into computer systems are continuously evolving to provide a more personal, efficient and user
friendly experience. This has further extended onto systems that recognise contexts and situations allowing less
user inputs and more about understanding and analysing the user's preferences.
3. Key Information
3.1 Framework
Context aware design is the concept of computer systems being attentive of the user's setting or context. It will
recognise engagement and interactions from the user and model the situations to accomplish a set task or
purpose. The fundamental framework of context aware designs takes into consideration a user's personal needs
which may be affected by many factors such as habits, self–image, and issues of motivation. Thus, many
questions are raised and answered in the planning process regarding the purpose, intended audience, inputs and
outputs required etc. to design such technologies that are able to understand and interpret what the user's goals
are. The prototype examples exhibit endless possibilities and

Generators Primary Heating Water Circuit Functioning
Generators–Primary Cooling Water Circuit functioning :
In order to distinguish the treated water from the secondary coolant (raw water, condensator etc.) it is named as
primary water because it is used for cooling stator winding, phase connectors and bushings . The secondary
cooling absorbs the heat from the primary cooler when water is circulated in a closed circuit by the primary
water cooler. The pump is supplied with in primary water cooler. Water is supplied to the flow paths of the
generator by supplying it to the primary water tank i.e by supplying it to tht primary water cooler through the
pump.
Flow path I :
Stator winding is cooled by Flow path I . This flow path passes through the stator bars via insulated barbefor
this it passes through the water manifold on the exciter end of the generator which is connected to thestatus bars
by a separate hose.Cooling water flows through hollow strands inside the bars. At the turbine end, the water
return to the primary water tank which comes from another water manifold which in turn comes from the
similar hoses.Minimum temperature rise is obtained for both the bars and the coolers because the water folw is
single pass through the stator. Movements are relatively minimised which are caused due to the different
thermal expansions between the bottom and the top bars.
Flow Path II :
Phase connectors and the Bushings are cooled by Flow Path II . The cooling water is circulated through the
thick walled copper tubes of the

A Cultural Profact : The Television As A Cultural Artifact
Essay #2

The TV as a Cultural Artifact
There are many different possibilities that come to mind when thinking about the typical culture of Canadians.
One of the most prominent artifacts that are typical of our culture is television. The television can be described
as an electronic device that receives signals and displays them on a screen, then turns them into visual moving
or still images. Those images then come together to tell a story. Due to the portability and accessibility of
televisions, they have become very easy to acquire, becoming a central part of the household for many. This
also does, however, cause an increase in probability of excessive use of this device resulting in poor health. It
also can be a catalyst of many ideas, good or bad, and affect people's opinions on important matters.
Some negative health outcomes are attributed to television. There is that of becoming the "couch potato", many
of us base television around our lives, and some of us get lazy and spend too much time watching television
which can result in health problems. Not only is watching too much TV and being sedentary a bad thing, but the
overwhelming amount of advertising and marketing that we see on television causes an increase in intake of a
range of unhealthy products. Each hour per day increases the risk of developing diabetes by 3.4%. A variety of
other potential behavioral and physical effects exist such as poorer social relationships, less fertility in men,
developmental

The Effects Of Television On Our Health
Jacoby stated in his article "Silent that Idiot box" that letting your children watch too much television can ruin
them in the long run. Television has the ability to lead children to violence and destroy their innocence.
Television can be pleasing to the eye. According to Jacoby children don't become educated from watching TV.
The more TV they watch, the less educated they usually end up. I agree with him because when I use to watch
television I would feel extremely sluggish and not want to do anything else. Watching television can have some
effects towards your overall health. It also can lead to bad habits and prevents you from having a better outlook
on life around you.
Watching too much television can have a serious effect on one 's motivation and abilities to interact with the
outside world. For example, Scarface is about Gang related activities and Drug abuse and is very aggressive. It
can be so engrossing. It can make a child wonder what his life would be like if he was in the main character 's
shoes. If parents watch a violent show or movie with their young children around, the children will have
problems. They will develop learning difficulties and have trouble paying attention in class. Not communicating
with your friends and family is also a health problem, a person could get depressed, have social anxiety, or
become delusional. People can even become sleep deprived.
What normally happens when you watch television? You usually stay there dazed for many of

Ectopic Pregnancy In The United States
Introduction The topic I choose to do was Ectopic pregnancy. In a normal pregnancy, the ovaries release an egg
into the fallopian tube. If the egg meets with a sperm, the fertilized egg moves into the uterus but in an Ectopic
pregnancy the most common place for the egg to stay is in the fallopian tubes. Ectopic pregnancy was first
described and come to awareness in North Americans the 11th century; it often was a fatal complication of
pregnancy. In the 15th century (which is known as the middle ages era) pregnancy was believed to be the
outcome of a person being infertile. The first unreported ectopic pregnancy was described in the results of an
autopsy performed on a female prisoner who was executed in 1693. Given the fact that technology was not as
developed before the 20th century, the methods used where not smart tactics to help the woman and developing
embryo. Some of the main methods that were used included starvation, cleansing, bleeding, and even treatment
with highly toxic chemicals that where often used to kill tiny animals. The methods listed above would often
result in the death of woman who were diagnosed with a ectopic pregnancy in the early 1600's to the early
1700's. I choose this topic because couples who are infertile are now turning to other birthing methods such as
IVF. IVF is one of the causes of ectopic pregnancy.

Your stomach is feeling bubbly. Following those in charge on an interminable pathway. The waves are wild
horses, rearing up before crashing down onto the river, pounding the rocks with their stainless–steel hooves.
After finally reaching to the peak of the starting point, the doughnut–like tube emerges itself in the arctic water.
The sunshine that was so powerful just seconds ago is faint. Your legs thrashing against the freezing water that
steals warmth from every part of your skin. Sitting in a circular hole waiting for the adventure to begin. Holding
both handles and launching face first at a tremendous speed through whipping wind and breath–taking
acceleration. Steering with your feet to prevent coming to a complete halt.
Underneath the gloomy, dark, and murky water lies another world. The stream is a sleeping cobra. It lies across
the land in smooth undulating curves, peaceful in the morning light, poise and innocuous, yet it hides many
dangers. Its rapid undertow being the slightest of your concern. Your shoes are gently pushed against the rocks
from beneath, that are enveloped in slimy emerald algae. While the tube oscillates with the rhythm of the water,
you encounter many ponderosa pine trees. The alluring sight of the 235 feet pine trees is mesmerizing to see.
The scent of butterscotch and vanilla overtaking your nose as the sap is being warmed by the sun. Watching the
pine trees sway above in the howling wind, you lay hoping that a needle wouldn't drop into

Succinate Dehydonate Lab Report
Hypothesis: We hypothesize that reagent Malonate will inhibit Succinate Dehydrogenase (SDH) activity.
Background: Malonate, also known as propanedioate, is a classic example of a competitive inhibitor. Malonate
has a molecular structure that is similar to succinate, so it has the ability to bind to the active site of succinate
dehydrogenase and inhibit enzyme activity. However, malonate is sufficiently different from succinate that it
cannot be dehydrogenated. [1] Malonate working as an inhibitor to succinate oxidation is a popular occurrence.
Succinate is oxidized to fumarate during the Kreb cycle and the reagent's (malonate) inhibitory effect slows or
halts that important step from taking place.[2] A competitive inhibitor had a similar molecular ... Show more

My First Time I Went Tubing With My Best Friend Gracye
Overcoming A Fear
I am writing about the time I first went tubing with my best friend Gracye. It happened when I was 13 years old.
I was invited for the second time to my best friend's lake house and she forced me to go on her Parent's speed
boat. Before all this took place, on the way to her lake house we watched the "Teen Beach 2" movie and there
was a saying in that movie it was "Gonna march to the beat; gonna do my thing"this was significant quote
because i chanted it while I was tubing when I got scared. When we got to the lake house Gracye and I

When I was whipped off the tube, I had skidded across the water like a skipping rock. When I was pulled back
onto the boat I was cold from being submerged into the lake by the "whip." The sun dried the droplets up in no
time and I felt more confident in going back out after telling Mr. Laursen, Gracye's Dad, to go a whole heck of a
lot slower and "DO NOT WHIP THE TUBES," at least while I was on

Nicole's First Signs Of Ectopic Pregnancy
According to the American Pregnancy Association, an ectopic pregnancy is "a serious pregnancy complication
in which a fertilized egg secures itself to an area outside of the uterus. This is typically in an area that is not
meant for a developing embryo, such as the fallopian tubes." In the initial case study presentation, the patient,
Nicole, was experiencing symptoms of an ectopic pregnancy. Nicole's first signs of an ectopic pregnancy were
that she felt very nauseous, was dizzy, and began to vomit. Within the next few days, Nicole began to feel
abdominal pain in the muscles, the nausea resumed, and traces of blood were found in her urine. According to
the Mayo Clinic, some signs of an ectopic pregnancy are "nausea, vaginal bleeding, and abdominal ... Show

The main symptoms that occurred in the initial case study for us to distinguish this as an ectopic pregnancy was
the nausea, traces of blood in the urine, and the abdominal pelvic pain. Abdominal pelvic pain occurs in ectopic
pregnancy because the zygote falls into the fallopian tube instead of implanting itself into the uterus. The
patient then took a physical exam in which some irregular results were found. The patient had sharp pains
running through the abdomen and swelling of the lower right quadrant. These symptoms correlate with an
ectopic pregnancy in that the fertilized egg could be implanted in the abdominal area. Also, in the physical
exam, endometrial bleeding was discovered which is typically found early on in a pregnancy. Lastly, the
physical exam showed that there were enlarged nodes in the submandibular, axillary, and inguinal regions.
These irregular results lead us to believe that there is an abnormality in the pregnancy. In the blood chemistry
panel, two results were found to be extremely higher than the reference range. They were estradiol and
progesterone. According to the Walk–In Lab, "estradiol is only seen in the blood in large amounts during
pregnancy." When estradiol levels are high and continually increase in steady amounts, this indicates that there
is a pregnancy. Progesterone is used to detect if there is either infertility or a failing

Lee De Forest
Lee De Forest was born Aug. 26, 1873, Council Bluffs, Iowa. De Forest was the son of a Congregational
minister. His father moved the family to Alabama and there assumed the presidency of the nearly bankrupt
Talladega College for Negroes. Excluded by citizens of the white community who resented his father 's efforts
to educate blacks, Lee and his brother and sister made friends from among the black children of the town and
spent a happy although sternly disciplined childhood in this rural community. (Kraeuter, 74). As a child he was
fascinated with machinery and was often excited when hearing of the many technological advances during the

The audion helped AT&T set up coast–to–coast phone service, and it was also used in everything from
radios to televisions to the first computers. (A Science Odyssey: People and Discoveries, 1999). By the time he
died he had over 300 patents, but few of them ever had much success. In fact, De Forest seemed to have a long
streak of failures. He was regularly involved in patent lawsuits (indeed, he spent his fortune on legal bills). He
went through four marriages, had a number of failed companies, was defrauded by his business partners, and
was even once indicted (but later acquitted) for mail fraud. (Kraeuter, 79).
With the audion, however, De Forest had a solid success. De Forest has been labeled one of the fathers of the
"electronic age," since the audion helped start the explosion of electronics earlier this century. American

component of all radio, telephone radar, television, and computer systems before the invention of the transistor
in 1947. (Kraeuter, 79). Forest passed away on June 30, 1961 in Hollywood, CA. De Forest wrote an
autobiography entitled Father of Radio, but did not get that recognition from the rest of the world. He is
remembered as one contributor to an industry that was, truth, the work of many people. (Kraeuter, 79).

INTRODUCTION:
Mitochondrion produces the energy that cell needs by breaking down sugars, fatty acids and amino acids to
CO2 and H2O. In this process, which is called cellular respiration, the chemical energy in sugar, fatty acid and
amino acid molecules is captured as ATP. Krebs cycle is a part of the cellular respiration that consists of series
of reactions. And succinate dehydrogenase is one of the enzymes that is used in this cycle. It basically catalyzes
the oxidation of succinate to fumarate. In this reaction, succinate reduces a FAD molecule, which eventually
donates its electrons to coenzyme Q. However, Azide prevents FADH2 from giving its electrons to coenzyme
Q, rather than an artificial electron acceptor, DCIP takes the electrons. DCIP is a dark blue solution that gets
lighter as it gains electrons. As DCIP gets lighter, its absorbance will decrease. So, the rate of the reaction can
be relatively observed by looking at the absorbance values of DCIP since the reaction processes, DCIP gains
electrons and gets lighter in color. By spectrophotometry we took the absorbance values. Spectrophotometer is
used in the process, which sends beams of light to the sample and measures the intensity of the light that passes
through the sample. This way we can

Observation: Last week, a ball dispenser was out for the children to play with. It was on the top of the shelf and
"Child A" was trying to reach for it. "Do you want the ball dispenser 'Child A'?", I said. I took it from the shelf
and put it on the floor; "Child A" sat down. I pressed the switch and the ball came out from the ball dispenser.
He smiled and I said, "Oh! There it is!" as the ball rolled on the floor. He stood up walked towards the ball and
picked it up. He walked back and put the ball into the ball dispenser. He stared at it for two seconds and he
looked at me and said "ooh" as he raised his hands on his side. I said, "Where is it, 'Child A'? Where did the ball
go?". I held his hand and guide it towards the switch, and pressed it. He laughed and I clapped my hands when
the ball came out from the dispenser, "Yaay! You found it, 'Child A", I said. He imitated me and clapped his
hands as well. He put the ball in again and stared at it; I kept on looking at him to see if he would press it. He
kept on looking at me and on the candy dispenser while saying, "Ooh ohhh". "Where is it, 'Child A'? What do
we have to do?", I said. He was still looking at me and on the ball dispenser. I assisted his hands on the switch
again and after three tries he did it by himself. Earlier today, children were playing with the ball dispenser as

A Research Study On Using Ng Tube Feeding
When a patient no longer has the desire to or appears unable to feed themselves orally, a request for a feeding
tube ensues completion by the nurse. Specifically, when a patient has prolonged bleeding, facial trauma, upper
GI blockage and cancer. An enteral tube feeding nasally situated has capabilities for only a short period of time.
The NG tube catheter tip normally resides inside the stomach or in the small intestine past the pylorus. The
number one complication involved with the use of NG tube feeding persists as incorrect placement. A nurse can
unintentionally place an NG catheter into the lungs, most notably when a patient has little to no gag reflex.
Completing a test for gastric contents, pH or performing a chest x–ray after inserting an NG tube for
confirmation of proper insertion. Another major complication when using NG tube feeding is aspiration within
the lungs due to gastric substances enter the trachea and into the bronchial spaces of the lungs. Keeping the
head of the bed elevated greater than 30 degrees will reduce aspiration to least possibility. Applying a
gastrostomy or jejunostomy tube for enteral feedings when NG tube has interfered with therapy or ensues

Lab Report On Turnips
The experiments were performed in the science lab 1.226 at the University of Texas Rio Grande Valley,
Edinburg on October 2, 2017. The experiments were performed in a two–day process due to lack of time.
Instructions were given by our TA on where to find the substances (guaiacol under the fume hood, turnip
extract, peroxide, and distilled water were placed on our lab tables in dropper bottles, along with the
spectrophotometer) and were told to get started. In activity 1 we will be testing 3 concentrations of an enzyme
(0.5 ml, 1.0 ml, and 2.0 ml of turnip extract). To quantify the rate of reaction in turnips, guaiacol will be used as
the color reagent. Guaiacol is oxidized when it encounters peroxide, allowing light at 470 nm to be absorbed
and allowing us to measure the absorbance. In the first activity from experiment day 1, three test tubes were
obtained and two clean cuvettes from our lab TA, and placed in a test tube rack on our lab tables. We used one
of the test tubes to make the control, another to make the substrate and the last one to make the enzyme. We did
this process 3 times to test the effects of the low enzyme concentration, medium enzyme concentration, and
high enzyme concentration on the enzyme reaction rate. For the low enzyme concentration, on the control test
tube we added 1.0 ml of guaiacol, 0.5 ml turnip extract, 0 ml of peroxide and 8.5 ml of distilled water, getting a
total volume of 10 ml in the test tube. For the low enzyme concentration, on the

Electomy: Unilateral Salpingo-Oophorectomy
Unilateral salpingo–oophorectomy is the surgical removal of a fallopian tube and an ovary. If both sets of
fallopian tubes and ovaries are removed, the procedure is called a bilateral salpingo–oophorectomy.
This surgery is performed to treat ovarian or other gynecological cancers, or infections caused by pelvic
inflammatory disease. Occasionally, removal of one or both ovaries may be done to treat endometriosis, a
condition in which the lining of the uterus (the endometrium) grows outside of the uterus (usually on and
around the pelvic organs). The procedure may also be performed if a woman has been diagnosed with an
ectopic pregnancy in a fallopian tube and a salpingostomy (an incision into the fallopian tube to remove the
pregnancy) cannot be done. If only one fallopian tube and ovary are removed, the woman may still be able to
conceive and carry a pregnancy to term. If both are removed, however, the woman is rendered permanently
infertile. This procedure is commonly combined with a hysterectomy (surgical removal of the uterus); the
ovaries and fallopian tubes are removed in about one–third of hysterectomies.

who use artificial products to make themselves look as we define to be sexy, this has torn a ridge in our society
in what we define as true beauty; true beauty is natural beauty, what you naturally look like without any

and women with the disease are not diagnosed and continue life without the proper support or treatment. Many
diagnoses are not acted upon until 8+ years later, as either symptoms are not expressed – only until the severity
of the disease increases – or the doctor/gynaecologist believes that the girl is too young to have a diagnosis. In
this case, if an 8 year old has her period or has become reproductive, the possibility of being diagnosed is

Fallopian Tube Vs Blood Canal
Did you know that when the heart contracts, blood pumps into the arteries? The fallopian tube is also called
oviduct, or uterine tube. The fallopian tube is a pair of tubes along which eggs travel from the ovaries to the
uterus and the blood vessels are the arteries which carry the blood away from the heart. Well, this is what my

The two systems in my drawing are the fallopian tube and blood vessels. The fallopian tube is a pair of tubes
along which eggs travel to the ovaries to the uterus. The fallopian tube has a small hair–like projection called

Soma is a means of mind control in Aldous Huxley's Brave New World. Soma is a drug given to the citizens of
the World State to make them more euphoric and to better accept their fate as citizens in this dystopian society.
The scientific basis of soma is that it is an opiate that makes the user feel happy; the user feels happy and is
therefore easily manipulated. It could be argued that soma is basically alcohol; people take it to escape from
reality and to feel better about themselves. Soma is significant to the novel because the government uses soma
to control the World State citizens and take away their individuality, which makes them easier to

The Uses Of Tube Feeding
The use of tube feeding is done when a patient is no longer or unable to feed themselves orally. When tube
feeding is required for just a short period of time an enteral tube feeding can be placed nasally. Incidences that
require NG tube feeding would be prolonged bleeding, facial trauma, upper GI blockage and cancer. The NG
tube catheter tip normally resides inside the stomach or in the small intestine past the pylorus. The number one
complication involved with the use of NG tubal feeding is incorrect placement. A nurse can "inadvertently"
place an NG catheter into the lungs, most notably when a patient has little to no gag reflex. As a result testing
for gastric contents, pH or performing a chest x–ray are required once an NG tube has been inserted. Another
major complication when using NG tubal feeding is aspiration within the lungs due to gastric "contents" enter
the trachea and into the bronchial spaces of the lungs. Keeping the head of the bed elevated greater than 30
degrees will reduce aspiration at "minimum". The use of a gastrostomy or jejunostomy tube can used for enteral
feedings when an NG tube cannot be tolerated of interferes with therapy. The gastrostomy tube, PEG, tip is
placed in the stomach and exits the body through the left upper quadrant of the abdomen where a bumper holds
it into location. This can only be placed internally by a doctor during an endoscopy, radiology or surgery. A
jejunostomy tube can be placed while in surgery, radiology

Obesity Is An Increasing Problem All Over The World And...
Obesity is an increasing problem all over the world and its prevalence differs from one area to another.
According to World health Organization (WHO) obesity is defined as body mass index (BMI) of 30kg/m2 or
more.1
It was reported that the proportion of obesity in surgical patients is greater than general population.2 This means
that anesthesiologists are going to deal with increased number of obese patients whose airway management is
one of their own responsibilities. Endotracheal intubation is more difficult in obese than in lean patients.3
Difficult tracheal intubation is defined by the American Society of Anesthesiologists (ASA) as tracheal
intubation requiring multiple attempts in the presence or absence of tracheal pathology.4 1 Failure of tracheal
intubation is one of the major causes of morbidity and mortality during anesthesia.5,6
Consequently, the use of new tools that increase the success of tracheal intubation, particularly in settings of
potentially difficult intubation, can have a profound clinical impact.
The LMA CTrach® is a modified intubating laryngeal mask airway, which incorporates an inbuilt integrated
fibreoptic system and a detachable battery powered LCD colour monitor with a light source that enables
visualization of glottis during intubation.7
King vision is a new portable battery powered video laryngoscope that is composed of reusable monitor and
disposable blade which may be channeled or non–channeled. It is used successfully for tracheal

A Rainbow Comes After The Storm Short Story
A Rainbow Comes After the Storm
Newaygo, Michigan, a small, little, suburban town north of Grand Rapids, Michigan. Their tubing and rafting
was a hotspot for families to spend quality time together. I was part of one of them. I was filled with excitement.
While we were waiting in line, we were cracking jokes and having a good time. "Group number 43, head your
way to the pink bus!" the announcer called. My family of 7 got onto the bus. It was my uncle, my aunt, my 6–
year–old cousin, Avi, My 11–year–old cousin, Preet, my parents and me. We were on the bus, in this strange
tiny town. We drove down the dirt road, down to the forest. I found this quite sketchy, but the only thing that
was in my head was jumping into the cold, crisp, and clear water as I imagined. Then, the bus began to shake as
the bus driver announced through the radio, "Don't be frightened, we are almost there! Just a few more of these
sharp turns and you'll be on your tubes down the refreshing water. Just remember to get off at the bridge, or
you'll be in deep trouble."
The bridge, the bridge, the bridge. I kept on repeating that in my head so I would not forget. Suddenly, everyone
started clapping. It was finally time to get off. Preet and I rushed to get the tubes for everyone in our family, and
some twine to attach it. We were filled with excitement. Time flew by, and we were finally on the dock. We got
our tubes tied up, and went into the water. The sun was shining through the dancing, tall, trees and everyone
was smiling. Groups started to pass us by, to the point we were isolated. We couldn't see anyone else in the vast
river. There was no possible way to get of neither. The land was all slanted, so you would have to climb, along
with that it was all private property. I was slightly worried about this.
"Mommy, is that a sea monster?" My cousin, Avi questioned. Then all of a sudden there was a BOOM! A tree
log stuck us. This tree log was gigantic; it looked like it weighed a million pounds. It was so big that we
couldn't get around it. We couldn't use it to hold onto as it was all mushy and wet. I thought to myself, should I
go under the log, but it's way too low, I would drown. We are going to be stuck here forever. We have nothing

Potatis And Its Effect On The Rate Of Osmosis
When osmosis, a specialized process of water moving across a semi–permeable membrane from a higher
concentration to a lower concentration, occurs, scientists can understand the events that occur when solute is
mixed with water (Readel 2000).
Many factors account for the varying ways that osmosis can change during the process. One factor is
temperature, in that the higher the temperature, the quicker rate the rate of osmosis whereas, the lower the
temperature, the slower the rate of osmosis. Osmosis occurs quickly in high temperatures because the
membrane becomes more permeable (as in can pass through more easily) and molecules move faster as heat
increases. On the other hand, Osmosis occurs slowly when it is cold because the membrane becomes less
permeable and the molecules move slower as heat decreases (Traxler 1927). Osmosis is different than diffusion
in that while a diffusion can occur in a variety of mixtures, osmosis can only occur when there is a semi–
permeable membrane. Particles are more limited during osmosis because only water molecules can move,
whereas any particle can move more freely during diffusion (Anne Marie 2017).
With gained knowledge from this experiment, our group performed another experiment and tested how certain
amounts of solute concentration impacted the rate of osmosis. We hypothesized that high solute concentrations
affected the rate of osmosis. Tubes with high solute concentrations were bound to show higher rates of osmosis
than tubes with

Social Learning With Chimpanzees And Other Animals
Learning by observation is a type of learning in which an individual observes the behavior of others, sees the
consequences of the behaviors, and then attempts to carry out the same behavior. Social learning is based on the
standards of classical and operant conditioning and observational learning. It is a commonly shared belief that
people have an instinctive ability to imitate the behavior of others. However, this ability is not unique to
humans. Animals have also showed evidence of being able to mimic humans and other animals (Mazur, 2013).
Chimpanzees, or Pan Troglodytes, have demonstrated social learning through many different experiments in
different settings. Chimpanzees have shown the ability to observe the behavior of a model and reproduce the
behavior. However, chimpanzees have also demonstrated the mental capacity of understanding when behaviors
do not elicit a desired reaction and not repeating these behaviors under these circumstances. This paper will
focus on chimpanzees and their ability to learn new behaviors through social learning. Marshall–Pescini and
Whiten (2008) discuss social learning with chimpanzees in East Africa, focusing on the task of nut–cracking.
Nut–cracking is unique to wild chimpanzees who live in West Africa, so this study intended to measure whether
or not chimpanzees who do not live in the wild in West Africa would demonstrate the same ability to learn nut–
cracking. The study took place on Ngamba Island in Lake Victoria, Uganda at a

Chemical Equilibrium Lab Report
Chemical Equilibrium Lab Report
Aim: The aim of the lab "Chemical Equilibrium" is to observe the effects of changes in concentrations of
products and reactants on the position of the equilibrium of given chemical reactions.
Background Information: We are going to use our knowledge of the Le Chatelier's principle in order to observe
this experiment. The principle states that the equilibrium will shift in the direction that will minimize the effects
of the change.
This lab consists of two parts.
[Part 1]
Procedure:
The solutions that we used were: * 5 ml of 0.1 mol dm–3 of FeCl3 * 5 ml of 0.1 mol dm–3 of KSCN
1. We mixed these two solutions in a 100ml beaker. 2. We added distilled water into the solution ... Show more
6. We added 1.0 mol dm–3 of NaOH into tube #7 until a change in color is observed. 7. We added 1.0 mol dm–
3 of NaOH into tube #8 and than added 1.0 mold dm–3 of mold dm–3 HCl until a change in color is observed.
Qualitative Data
Tube Number | #5 | #6 | #7 | #8 | Initial Color | Yellow | Yellow | Orange | Orange | Substance(s) added |
1.0moldm–3 HCl | 1.0moldm–3 HCl and 1.0moldm–3 NaOH | 1.0moldm–3 NaOH | 1.0moldm–3 NaOH and
1.0moldm–3 HCl | First Color Change | Orange | Orange | Yellow | Yellow | Second Color Change | Orange |
Yellow | Yellow | Orange |
Conclusion:
To conclude, the data we have collected from both experiments suggests that Le Chatelier's principles are
applicable and correct. When different substances were added to different solutions, the equilibrium shifted
appropriately in order to gain a balance. The shifting of equilibrium resulted in different color changes in
different mixtures. In part 2 of the experiment we the aforementioned changes were more easily spotted. We
saw the relationship between forward and reverse reactions. When NaOH was added to tube #8 we saw that the
color changed from orange into yellow, in order to gain balance but when we added HCl back, the color again
changed to orange. Which clearly proved Le Chatelier's

Chlh Greys Anatomy Essay
Ethics and the Media Project– Greys Anatomy
Dilemma
For this Media Project, I chose to watch an episode of a Grey's Anatomy that contains a medical ethics
dilemma. I watched Season 2 of Grey's Anatomy, Episode 23 "Blues for Sister Someone." In this episode, a
woman asks Dr. Addison Shepherd to clandestinely tie her fallopian tubes (tubal ligation) while she gives birth
to her 7th child through C–section. She does not wish to have any more children (seven is already a huge
burden), but her devout Catholic husband does not allow birth control. Hence, she pleads Addison to help end
her childbearing abilities (tying her tubes would be permanent birth control). She begs Dr. Shepherd to do the
surgery in private so here is no medical record ... Show more content on Helpwriting.net ...
One Perspective The perspective of the wife is that she has autonomy over her body and has the right to decide
whether or not she wants to continue having children. She already is exhausted from her current six children;
she has gone to the hospital from dehydration and exhaustion from forgetting to drink water for 3 days because
she was so busy taking care of her kids. With the birth of this seventh child, she has had enough. She does not
want to bear any more children. She believes that God will understand her situation and her reasons for
choosing and that she will be forgiven for giving up her fertility.
Other Perspective On the other hand, her husband Chris is a devout Catholic that follows everything that his
religion insists. The Pope says that birth control is not allowed, so he is against letting his wife take birth
control. To a Catholic, they live to reproduce; hence you are not supposed to use any form of contraception as a
Catholic. Tying tubes is viewed as a form of contraception. It's also important to consider the perspectives of the
physicians involved with the decision making process in this dilemma. From the perspective of Dr. Shephard,
the patient is her sole obligation and helping a patient get what they wish is important. On the other hand, her
associate Alex Karev is against tying the woman's tubes. He

Tube 1 And 2 Lab Report
Tube 1 and 2 contain functioning enzyme extract and substrate solution, ribose–5–phosphate. Furthermore, the
conditions in tube 1 and 2 allow the reaction to proceed to form ribulose–5–phosphate and the mount of product
formed can be measured. With tube 1 and 2 being identical, averaging the absorbance allowed minimizing the
error due to differences in enzyme concentration and contaminants within experimental procedure. Tube 3 is

phosphate isomerase activity. Tube 4 and 5 act as controls for the absorbance and the effect of substrate and
enzyme on the absorbance reading are investigate respectively. Tube 6 acts as a comparison for the known
amount of product whereby the absorbance of other tubes can be compared to tube 6 in order to calculate
amount of ribulose–5–phosphate present. Lastly, tube 7 acts a black for all the other tubes (1–6) because it only

Secondly, the sum of tube 4 (no enzyme) and tube 5 (no ribose–5–phosphate) were used to adjusted the
absorbance of tube 1 and 2 after using tube 7. As tube 4 only takes ribose–5–phospahte and tube 5 only contains
the enzyme extract, by taking the difference of the sum of these two values from the absorbance of one the full
tubes (tube 1 or 2) it allows to account for the absorbance caused by ribose–5–phosphate and the enzyme
extract. And the adjusted absorbance will indicate only the absorbance of the red complex formed by reaction
between resorcinol–hydrochloric acid and ribulose–5–phosphate. Lastly tube 3 (boiled enzyme) is not used as
denatured enzyme has a different absorbance compared to active enzymes, thus tube 3 cannot be used to adjust
the absorbance values (Kabacoff and Laken,

Fallopian After Genetic Fertilization
The creation of a new life is a complicated process where many sperm cells travel a long road just so they can
sacrifice themselves for that one lucky sperm cell. As you can tell a lot of deaths occur when the sperm cells try
to travel to the uterus most of them get lost along the way and don't take the right turns others just aren't lucky
to be chosen to be the one who gets to take over the egg. Once fertilization occurs that is when the sperm
penetrates the egg. That is called Conception, after three days of conception the fertilized egg starts dividing up

Ankistodemus: Fresh Water Pollution
The introducing to any type of pollution, man–made or artificial, can have an outstanding effect to a natural
environment. When the word of pollution is thought of, it's never a positive thought and can do harm to where
humans and many different organism lives. There are many different freshwater pollution and each one of
having it one effect. One of the organism that live is fresh water is Ankistodemus, a green alga that grows in
fresh water pond and lakes. When Sodium chloride (salt) is added to the alga environment what type of effect
will it have on its growth? The importance of this experiment to make aware of how pollution have a stern
effect on the living things around the Earth. Being alert of this will expression how putting more care on the
environment will extend the life span of the Earth. The goal of adding Sodium chloride, the pollutant, to water,

The connections of the circuit is shown above in the diagram. The connection shows that the entry exit is linked
to the 7 segment LED and thus using an arduino, we could make a simple system. The IR sensors were digital
and thus the connections are made to the digital side of the arduino mode. The 7 segment LED is connected to
the digital inputs of the arduino beard. The servo motor is also connected to the arduino board and the board
was programmed so as to give the desired output. The LED is fixed to number 9 in the beginning i.e. when no
car is in the parking lot. Then as the car enters the IR sensor detects the car, opens the barricade for the car and
reduces the number on the LED to 8. This continues till the number of the available parking lots are zero. Also
when the car exits, the number on the LED is increased by 1. When the number of available spaces is 0, then if
a car tries to enter, the door will not open.

In the further research, there are two more factors that should be added to make the system more reliable.
Firstly, IR sensors should be placed over every parking lot.

The Italian Anatomist Gabriel Fallopius Essay
Gabriel Fallopius was one of the most noteworthy and respected Italian anatomists of the sixteenth century. He

inside of today's reproductive system, how they looked like, or what they were. Gabriel Fallopius inspired so
many of his students to continue researching in the medical field who later became famous medical
professionals. Due to his very successful accomplishments, we are able to learn and observe more of the

great discoveries. One was he made and had the first proven documentation of the use and make of condoms for
sexual use (History Of Condoms). It was proven good and protective during sexual activity after he successfully
tested it on 1,000 men. Another major discover that had a big impact in the whole world was (Bookrag.com) the
accurate description, observation, and naming of the Fallopian Tubes (human oviducts). He correctly described
those resembling small trumpets. Without documentation (Yahoo Answers) about the Fallopian Tubes and how
it works, we wouldn't know much about it and the way it acts in the women's reproductive system. Its impact on
the world is that it helped medicine. For instance, an ectopic pregnancy can now be diagnosed and the woman
will live once the embryo is removed from the fallopian tube. When the discovery of the Fallopian Tubes
(Yahoo Answers), women would die once the embryo exploded in the tube which caused severe pain and sepsis.
The doctors back then didn't know what the problem was till Gabriel Fallopius discovered the Fallopian Tubes.

Pollution is a very wide–use term that means the introduction of contaminants that cause a negative change into
a natural environment. It englobes all sort of contaminations such as air contaminants, water contaminants, solid
contaminants on soil and a lot more. As we can see in the World Wild Life website, pollution is a very important
issue he have and that we have to fix as soon as possible. There are even natural substances considered as
pollutants once they exceed natural levels in a certain area.

Methods
In order to set up the experiment, twelve test tubes total were used; four of them were the control tubes, which
had no algae solution contents. The reason for not adding algae is that the control tubes solutions are meant to
be the starting point for comparison that has to stay the same throughout the length of the experiment. They are
used to set up the blanks on the spectrophotometer (instrument used to measure the amount of light at a specific
wavelength) for each of the remaining eight tube solutions. Each time a tube is read by the spectrophotometer,
the instrument needs to be set blank in order to read the change between the control tubes (no growth) and the
tubes with algae (unknown potential used growth). We have four different groups with different pollutant
amounts and fertilizer in order to measure the change respect to the percentage.
The control tubes were set up differently according to the table below. Negative Control tube Blank Tube 1
Blank Tube 2 Blank Tube 3 Blank
Alga–Pro 10 ml 9 ml 8 ml 7 ml
Pollutant 0 ml 1 ml 2 ml 3 ml
Total Volume 10 ml 10 ml 10 ml 10 ml
% Pollutant 0 % 10 % 20 % 30 %
As we can see in the table above, the negative control tube blank has 100% of fertilizer and 0% of pollutant,
tube 1 blank has 10% of pollutant, tube 2 blank has 20% of pollutant and tube 3 blank has 30% of pollutant,
understanding that the percentage left is fertilizer.

Separation of a Carboxylic Acid, a Phenol, and a Neutral...
Objective: The objective of this experiment is to use acid–base extraction techniques to separate a mixture of
organic compounds based on acidity and/or basicity. After the three compounds are separated we will recover
them into their salt forms and then purify them by recrystallization and identify them by their melting points.
Procedure:
Extraction of Carboxylic Acid
A pre–weighed (0.315g) mixture of Carboxylic acid, a phenol, and neutral substance was placed into a reaction
tube (tube 1). tert–Butyl methyl ether (2ml) was added to the tube and the solid mixture was dissolved. Next, 1
ml of saturated NaHCO3 solution was added to the tube and the contents were mixed separating the contents

Next, add concentrated HCl drop wise until the litmus paper indicates that it is acidic. During this procedure, I
added to much HCl because many CO2 gas bubbles evolved. This error in the experiment will cause the
recovery % to be lower.
Recovery of Phenol by Acidification
To tube 3 a piece of litmus paper was placed into the tube. Then as is tube 2 concentrated HCl was added drop
wise until the litmus paper indicated that it is acidic. No CO2 gas will evolve.
Purification of neutral substance
Tube 4 now should only have crude solid in the tube and it is then weighed. The tube is placed into a 50℃
water bath and then approximately 0.5 –1 ml of methanol is added, as well as H2O until the solution gets
cloudy, once the solution is dissolved it is cooled to room temperature and then iced. The crystals are then
collected using a Hirsh funnel. Next a small amount (~ 0.1g) of the crystals are placed into a melting point tube
and placed into the melting point machine to record the unknown neutral substances melting point.
Purification of Carboxylic Acid and Phenol
To tube 2 and tube 3 a boiling chip is added. The two tubes are boiled to remove any residual ether. Next, the
tubes are cooled to room temperature and placed into an ice bath to allow for crystallization. The solution is
then removed from the solid in each tube and discarded. To tube 2 and 3 ~0.5 ml of H2O is added for
recrystallization, the tubes

The Design Model Developed By Sister Callista Roy
In the clinical setting, nurses must evaluate their patients in order to better understand their needs. Multiple
conceptual models exist in order to guide the evaluation process as well as to enhance the nurses' scope of
practice. The focus of this paper will be based on the Roy Adaptation Model developed by Sister Callista Roy,
in which the model will be explained, analyzed and discussed through a clinical situation. Presentation of the
conceptual model Sister Callista Roy established her first publication of the Roy Adaptation model in 1970
defining nursing as "enhancing life processes to promote adaptation" (Roy, 2009, p.28). Many theorists, such as
Helson and von Bertalanffy, inspired the creation of her own model (McEwen & Wills, 2011). The two core
principles that make up this model are humanism and veritivity (Pepin, Kerouac & Ducharme, 2010).
Humanism describes the importance of the subjective dimensions of a person while the term veritivity, created
by Roy, is "the principle of human nature that affirms a common purposefulness of human existence" (Roy,
2009, p.28). Consequently, the Roy adaptation model emphasizes the need to adapt. It assesses the interaction
and effect the environment may be having on the patient while undergoing the disease process or experience.
Thus, the environment and the patient's health are interchangeable. The modes of adaptation consist of the
physiological mode as well as three psychosocial modes, which are broken down into

Furthermore, the history of the Internet is part of the reason why the Internet is so distinctive from the other
kinds of networks; specifically, the history of the development of the internet as a mean of communication gives
a proper insight on the distinctiveness of it. First of all, communication and computers came up together around
1963, when the key improvement was to make these new technologies connect with each other. The first critical
step in the history of the internet as a network was made by Leinrock (1961) when he put forward the first
packet switching theory. He was convinced that packets, "the unit of data that is routed between an origin and a
destination on the Internet or any other packet–switched network" (TechTarget,2007), were more practical than
circuits for the functionality of communication between networks. Moreover, Roberts(1965) created the "first
(however small) wide–area computer network ever built" TechTarget (2007), which demonstrated that
computers could work together. Thank to these discoveries in 1968 Roberts, came up with the first form of the
internet: the ARPANET. The internet started to advance faster and faster with fundamental improvements such
as the TCP (transmission control protocol), a system that allowed data to be transferred, and the creation of the
PhoneNet, the first dedicated email server online. These improvements brought to the creation of the Web 2.0
