The Conflict Of Outstanding Magnitudes Is Happening

The Conflict Of Outstanding Magnitudes Is Happening
Today I woke up and realized how shaded the world is. I turned on the news and seen the country
headed to a dark place because a White police officer shot and killed an unarmed Black child. Being
Black has never been easy in United States. Growing up my mother always told me that you are
born with two strikes against you already. She would say, "You are a male and you are Black." I
never understood what she meant until I had opened my eyes. At this point in United States' history,
a conflict of outstanding magnitudes is happening. The goal is to get United States to recognize that
there is still abundant amount of work to be done to eradicate the wrongdoings that have been
committed and continued against Blacks in this democracy. After years of hard work, and leaving
many without any way to advance in a reasonable standard of living, does United States truly
believe that it has freed itself of this circumstances by screaming, "You are equal!" A Black man
goes into an interview after calling to make sure that it is still a job opening. After seeing the man in
person, the owner of the store becomes uncomfortable and says that the job is filled. This is an
example of what happens to Blacks on a day to day basis. Being a Black man in this country is
compared to being a superhero. Heroes love and try to uphold the honor of being a human, but he
can't intermingle inside the communal limitations of the civilization without behaving according to
socially acceptable conventions or

Pre-Industrial Astronomy
While researching "pre–industrial astronomical accomplishments," it seemed that a good majority of
the accomplishments being highlighted were those of the Mayan and Aztec civilizations. Feeling
that these topics may be over–researched, I decided to turn my attention towards the
accomplishments of those in a different area of the world. After switching my focus to the pre–
industrial astronomical feats of ancient Greek scientists, I have found that in many cases, these
scientists contributed more than one idea, finding, or apparatus to the field of astronomy. For this
research, I decided to hone in on the contributions made by Greek scientist Hipparchus. Throughout
his magnificent life, and all before the implementation of modern technology, ... Show more content

For example, the features of the astrolabe became more improved and functional by the middle ages.
In this way, the astrolabe can be compared to a modern–day computer, in which more and more
desirable features are added over time. While a modern audience would show excitement over a
computer that boasts a touch screen monitor or a detachable keyboard, improved astrolabes boasted
supplemental disks that could be used for trigonometric calculations, peepholes through the body of
the device that would allow the viewer to create a map of the sky, indicators that would point to
important stars, and a ruler that would render the user able to measure celestial bodies (Meech,

Morecambe Bay: Environmental Analysis
We sampled the biota across a range of spatial scales at six sites within two locations, Essex mud
flats and Morecambe Bay in summer 2013. Within each of two locations, sampling was undertaken
at Fingringhoe Wick (FH), Abottshall Marsh (AH) and Tillingham Marsh (TM) in Essex, and
Cartmel Sands (CS), West Plain (WP) and Warton Sands (WS) in Morecambe Bay. In order to
determine how changes in spatial scale affected food web structure and ecosystem processes, we
sampled each site at four spatial scales within a range of varying lag, i.e. 1 m (n=1), no less than 10
m apart (n=3), no less than 10 m but no more than 100 m apart (n=6) and no less than 100 m apart,
but no more than 1000 m apart (n=12), resulting in 22 samples within each site, defined by marked
quadrats. By calculating the mean distance (i.e. lag in m) between the samples at each scale, we
made lag a continuous variable. We extensively sampled the benthic fauna associated with each
quadrat using sediment cores, and fyke nets to catch larger mobile species such as crustaceans and

Trivariate features were assessed using abundance and mean body mass data, as well as univariate,

the well documents allometric scaling relationships between predator and prey body mass ratios aij~

October 21st, 2012
Introduction
Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of
flexion of the cantilever. Hence, the objective is to establish a relationship between the length of a
cantilever, which may give some insight into the physics of cantilevers.
Hypothesis: If one increases the length of a cantilever, one would expect there to be an increase in
deflection/flexion of the cantilever. Similarly, if one increases the mass of the load, one would
expect there to be an increase in the deflexion/flexion of the cantilever. In addition, I predict that
proportionality will also occur ... Show more content on Helpwriting.net ...
* Dependent Variable: The deflection/flexion of the cantilever in metres. This will be measured
indirectly by measuring the initial height of the bottom of the cantilever with no mass added (which
is equal to the height of the table) and the new height of the bottom of the cantilever after each trial,
which will be measured with mass added. Hence, the difference between these heights is equal to
the deflection/flexion of the cantilever. The material and other physical properties of the cantilever
will be controlled by using the same yardstick as a cantilever for each trial.
Data Collection and Processing
My experiment is divided into two parts; experiment A (involving the relationship between flexion
and the mass of the load) and experiment B (involving the relationship between the flexion and the
length of the cantilever).
Below are two tables in which I have recorded the data which I obtained during the experiment. The
first table reflects the Relationship between the deflection/flexion of the cantilever and the mass of
the load and the second table reflects the relationship between the flexion of the cantilever and the
length of the cantilever.

All of Summer in a Day is a tale from the far off future, when humanity has colonized Venus. Once
every seven years for only about two hours, taking place in a class room of young children, most of

Sun and tries to explain it to her fellow class mates who believe she is lying. On the day the Sun is

her while the Teacher is out. Later the Teacher arrives back in the room and, not realizing Margo is
not with them, takes them outside for the 'Summer'. When the children come back in due to the

The Road Less Taken reveals that while it might be best to follow the road most traveled so that you
can compare experiences with others who have also, it is a more unique experience to take the road
less traveled. The Road Less Traveled and All of Summer in a Day may seem to be along two
different themes; however, there is one part that ties these to tales together, Margo. Throughout her
time on Venus, Margo has held onto her unique experience of the Sun and though trying to share it,
others refuse to accept it as true. By the end of All of Summer in a Day the children who locked
Margo in the closet, see that her unique experience, her road less traveled was worth much more
than their dull illusion that there is no sun, or that it is something

contrast, nowadays, the installation process of the blogging is a simple automated process, which
involves ability to type on QWERTY keyboards and use internet, thus people with the least skill can
easily become a blogger. For some bloggers, weblog can serves simply as a space for daily journals
or a quick memo of their thoughts, since the main attribute of the weblog is personal expression.
Nonetheless, the blogging software is being commercialized and marketed for business purpose. So
far, "few businesses have adopted blogging for use by employees on company time... John Robb,

I arrived at the scene and could distinguish the spot where the sand has been tossed. I started to dig.
My arms began to ache and felt burning hot but I ignored the pain and strived on. I must have dug
over one metre of sand and I could still see nothing. I noticed a hint of movement out of the corner
of my eye. I glanced around to check if anyone was there but I could see no one, just the man in the
moon. Suddenly I heard a thud. I had hit something. I fell to my hands and knees and brushed off
the rest of the sand. The box had handles on it and I used them to lift it out of the sand. The lid was

Main Methods Of Measuring Astronomical Distances
Main methods of measuring astronomical distances:
Scientist used different type to find the astronomical distances. Cosmic distance ladder is used to
find the astronomical distances, which includes five different methods to find the astronomical
distances.
Radar ranging:
Radar ranging is used to find the distance of the planets which are near. This method works by
striking a beam of radio waves towards the object, the radio waves after striking the object will
come back as echo. So, the time taken by the radio waves to come back in the form of echo can be
used to find the distance of the object.
Parallax:
Parallax is used to find the distances of the stars which are near. This method works by measuring
the distance of object from two different positions. First you measure the distance of the star from a
specific position and then after six months when the earth is on the opposite direction of the sun we
measure the distance of the star again. At that position, the star appears to move slightly than last.
The parallax angle the star makes can be used to find the distance of the star through the help of
trigonometry.
Main sequence fitting:
Main sequence fitting method is used to find the distance of the clusters of the stars. Clusters is
group of stars which are next to each other. This process works by finding the apparent magnitude of
the cluster from the earth. Then, we find the distance of the exact distance through the help of
parallax methods. This distance of the

Why Did Salt Grow In River Essay
The Effect of Salt on Radish Seed Growth along the Nelson River in Ensi county, Indiana.
Autumn Acord
Radish farms along the Nelson river had a recent lack of growth of their radishes. A landfill and a
salt storage facility had recently opened along the river near the farms. Samples from the river were
taken and used to grow radishes to see what caused the lack of growth. The salt storage facility had
leaked into the river, causing samples B and D not grow.

It was in the middle of Nelson River between irrigation pumps. There was an abundance of salt and
it was not able to dissolve or become diluted enough for the plants to grow. This helps prove that the
salt is the reason why the radish seeds were not growing on this farm.
Each seed with Site E water grew on average 7.625 centimeters. Site E was located after Kimmel's
Creek joined in with the river, where Kimmel's Creek brings fresh water and helps dilute or dissolve
the salt. All this data helps find the reason why the farmers are having problems with growing their
crops by the Nelson River.
The hypothesis that was being tested was if the salt facility was leaking salt, then the crops will not
grow. The hypothesis was supported by the data gathered because it proves that the seeds in the sites
located near the salt facility did not grow at all, but the other seeds did when they were not affected.
Site B and D's seeds did not even sprout and they were located either by the salt facility or slightly
downstream. Site Cand E was farther down the river and was not affected by the salt. Site A was
completely before the storage facility and was not affected in anyway since it was the control of the

An Project On Water Resources
Objective: This project focuses on water resources in the region of ancient Eastern Arabia at the site
of As Safah, Oman. This site has archaeological evidence of metallurgical activities in the Iron Age
(c. 900–600 BCE), like kilns, furnaces and metal objects, still in very good condition. However, the
site is very far away from any natural water sources in the present day. Excavators did find sediment
and fluvial deposits suggesting that occasionally in the past the site had an inflow of water (Genchi,
Giardino, and Castelluccia 8). The objective of this project was to use satellite imagery to
understand why this site was chosen for intensive metal production despite it distance from water,
necessary for metal production. This ... Show more content on Helpwriting.net ...
Later that year and throughout 2013, excavators worked on the site, conducting surveys and digging
test trenches. Excavators found kilns and furnaces, layers of floor, and metal objects, like ax heads,
swords, daggers, and sledgehammer heads in very good condition. Excavators believe it is a very
well preserved site because of the formation and rapid movement of the desert sands which covered
up the site relatively quickly after it was abandoned (Genchi, Giardino, and Castelluccia 3–4). Sites
with similar metal deposits dating to approximately the same time have been found in the region, at
Ibri, for example, 50 km west of As Safah (Yule 39–40). The site itself has been delineated into As
Safah 1 and 2 based upon the deposit of material found on either side of a large dune belt (Genchi,
Giardino, and Castelluccia 3). As Safah 1 measures approximately 80,000 m2 and As Safah 2
measures approximately 17 hectares (Genchi, Giardino, and Castelluccia 11). The surrounding area
is made up of a wadi and dune deposits and the annual precipitation is less than 50 mm. As a result,
large amounts of rainfall will cause flash floods in this and surrounding low areas (Genchi,
Giardino, and Castelluccia 5–6). The site does not appear to be close to a fruitful water source. The
entire region is hyperarid and not conducive to farming. The rain comes erratically by the year, some
years being better than others (Potts 165). The location does offers other advantages which

First Magnitude Scale Lab
The purpose of this particular lab is to learn the magnitude scale and more about an alternate
measurement astronomers use to designate the luminosity and apparent brightness of stars. When
the Greek scientist Hipparcos determined the brightness of stars he did it by eye. The first stars that
came out at night were the first importance and today we call those stars "first magnitude". After the
year's astronomers start realizing how some stars are brighter than others and that's when they form
a magnitude scale. Magnitudes and brightness are related to each other, but magnitude scale is a
difference subtractive scale and the apparent brightness makeup a multiplicative scale. I believe that
it's important to do this lab because we can understand

Analysis Of All Summer In A Day By Ray Bradbury
Could you envision a planet that sees no sun? In the story, "All Summer in a Day," Ray Bradbury
draws us in, as readers, with a story that takes place on the planet Venus. The environment of Venus
is as described in this quote, "It had been raining for seven years; thousands upon thousands of days
compounded and filled from one end to the other with rain, with the gush and gush of water...fall of
showers and the concussion of storms so heavy they were tidal waves come over the islands..."
(Bradbury, 1954) The only one that has experienced and remembers the sun is a young girl, Margot.
Margot lived on Earth until she was four years old, unlike the others who have been living
underground in Venus for their entire lives. Because of this, Margot is constantly facing problems
regarding her classmates' jealousy of her past opportunities. Without the sun, she has become, as
Bradbury writes, "...a very frail girl who looked as if she had been lost in the rain for years and the
rain had washed out the blue from her eyes and the red from her mouth and the yellow from her hair.
She was an old photograph dusted from an album, whitened away, and if she spoke at all her voice
would be a ghost."(1954, Bradbury) In this short story by Bradbury, the theme is that jealousy and
ignorance can blind us from seeing things how they really are. This is shown time after time when
Margot is harassed, depressed, and isolated because of her classmates' jealousy.
To begin, a way that Bradbury shows us that jealousy and ignorance can shield a person from the
truth is through the main character, Margot, who is constantly being harassed by her classmates. The
only reason Margot's classmates harass her is because she remembers the sun. This makes her
different from all the others, who have lived here on Venus since birth. In this way, they are
uneducated or ignorant because they have never experienced the sun. Because she is different, the
classmates take every chance they have to harass her in any way they can. Right before the sun
came out, one of the rare events that Margot was greatly anticipating, the classmates "...surged about
her, caught her up and bore her, protesting, and then pleading, and then crying, back into a tunnel, a
room, a

Childhood obesity is no different. In the United States, 36.5% of adults are overweight or obese,
17.0% among U.S. youth.1 Childhood obesity rates have continued to soar over the recent years,
along with the health problems resulting from obesity. While there is no question about the rapid
increase in overweight or obese children in the United States, the causes and solutions are less
transparent. Children are more susceptible to the obesity epidemic, they have fewer tools to deal
with the increasing and overwhelming number of factors that contribute to the epidemic.3 Some of
which include the limited access to healthy affordable foods in low–income areas, increased portion
sizes, and greater available of sugar–sweetened foods and beverages.1 There are a plethora of health
problems that are caused by obesity. To name a few, high blood pressure and high cholesterol, type 2
diabetes, breathing problems such as asthma, fatty liver disease, low self–esteem and low quality of
living, and impaired social, physical, and emotional function.1 Additionally, childhood obesity leads
to premature mortality in adulthood as well as physical morbidity. The effects of childhood obesity
do not end when a child outgrows an age, it continues with them and has impacts for the rest of their
lives.2 There are a variety of intervention and prevention strategies that have been executed to
attempt to

The Relative Importance Of Four Variables As Possible...
The Relative Importance of Four Variables as Possible Indicators of Wake Length.
Introduction
In rivers there are objects that cause more of an obstruction to the overall flow and so generate more
resistance than the surrounding grains. This is because they are larger than the bed's grains and thus
they are sometimes known as large roughness elements. Large roughness elements are an important
feature in the river bed since they block the path of the flow. Obstructions embedded in a bed such
as stones can cause flow separation which results in phenomena such as detachment of boundary
layer and turbulent wakes (Charlton, 2008, p. 81 & 87). The flow is separated into three parallel
flows that combine at a later point downstream. Between these ... Show more content on

Stone length shall henceforth refer to the length of the stone parallel to the overall direction of the
water flow. Stone length was determined using two measurements of length which shared the same
starting point: The upstream beginning of the artificial bed. The first was measured to the upstream
end of the stone while the second was measured to the downstream end of the stone. Stone length
was obtained by subtracting the first measurement from the second measurement. Stone protrusion
shall refer to a measurement taken perpendicular to the flow and approximately parallel to gravity.
Stone protrusion was determined using two measurements of depth: The first was the depth of the
water above the artificial bed. The second was the depth of the water above the stone. Stone
protrusion was obtained by subtracting the second depth measurement from the first depth
measurement. Stone width shall refer to the measurement taken perpendicular to the both flow and
gravity. Stone width was determined by directly measuring the stone along the widest possible
perpendicular axis to both gravity and the direction of water flow.
Empirically determining the properties of the artificial bed was neglected. However a few properties
can be estimated or stated: The smallest grain sizes in the bed were approximately 1cm. This was
due to the process used for selecting grains when the artificial bed was created. The maximum grain
size did not exceed the size of any of the stones

The Response Of The Sciatic Nerve
The study of the response of the sciatic nerve and the neuromuscular to the Rana pipens was
constructed by the Comparative Animal Physiology lab manual for both the nerve compound action
potential (Lab five) and the neuromuscular junction (Lab six) (Norris, et al.,2016). In order to
analyze the responses of the sciatic nerve and the gastrocnemius of a Rana pipens, one exercise was
selected from Lab five and five exercises were selected from Lab six. Both lab five and Lab six had
a study length of three weeks to be performed. Therefore, the first experiment focused on the nerve
compound action potentials, while the second experiment focus on the neuromuscular junction. In
the first experiment, the only exercise analyzed (Exercise one), was the determination of the
threshold voltage and the relationship between stimulus intensity and compound action
potentials(CAP). On the second experiment, five exercises were analyzed, these experiments
focused on the stimulus intensity and strength of contraction, the effect of stretch on contractile
force, the effect of paired pulses on contraction force(summation), muscle tetanus, and muscle and
nerve fatigue. In lab five, exercise one, which focused on the determination of the threshold voltage
and the relationship between stimulus and intensity and CAP of the Rana pipens the materials used
were; a computer system, PowerLab with analog output, LabChart software, MLT012/B Nerve
Bath, Frog Ringer's solution, isolated

The Change in Resistance of a Carbon Paper
The Change in Resistance of a Carbon Paper
Introduction
The aim of this experiment is to see how the resistance of a carbon–coated piece of paper changes
when the different variables change.
Variables
A variable is a change in an experiment that could alter the outcome/results of that experiment, and
for this experiment the main variables are type of paper, width of paper, length of paper, and
temperature.
We are going to be studying how changing the width of the paper affects the resistance, and so to
ensure a fair test we will have to keep all of the other variables constant, as if they were also
changing the results could be affected and the experiment would not be of any ... Show more content
Preliminary Experiment
The purpose of the preliminary experiment was to decide on an appropriate length to keep the paper
constant at, and an appropriate shunt for the ammeter. The layout and format is the same as the main
experiment (see later).
We tested the various ammeter shunts, and decided to use the 10mA shunt, as it gave a reading in the
middle of the scale, whereas the other shunts had given readings off or almost off the scale.
We also found that 32.5cm was the optimum length for the paper, as it puts the reading at about 10
on the scale, which is a good as it ensures that as we decrease the width (hence decreasing the
amperes), the readomg will not go off the scale as it was high to start with– if we had started with a
length that put it at something lower like 3 to start with, it could have gone off the bottom of the
scale and we would have to start over.
Apparatus
–Electric wires

–Ammeter (and shunt)
–Voltmeter
–Carbon–coated paper
–Scissors
–Ruler
–Cyclon cell
–Clips
Diagram
The diagram below shows how we will set up the apparatus, in a standard circuit diagram.
The clips are clipped onto both ends of the carbon–coated paper, and so the current can flow through
it. The width of the paper will start at 7cm, the length at 32.5cm,

A Study On Inverted Topography
Abstract
Inverted topography in a different of scales from large scale to fine scale has been observed in
numerous localities on Martian surface. Also, Inverted wadis in Western Desert of Egypt in seven
sites cover an area of about 26.000 square kilometers, provide us a natural museum for a different of
scales, mechanisms of development, and planimetric patterns. Therefore, we carried out field study
in four sites of inverted wadis in Gabal El–Na'aloon, east of Baharyia, west of Ghard Abu Moharik,
and west of Tahta city rane with laboratory analysis for collected samples. In this paper, we shed
light on the morphological, sedimentological, and mineralogical aspects of inverted wadis in
Western Desert of Egypt. We conclude that the majority of minerals which led to the cementation of
inverted wadis in visited sites, are calcite, iron oxide, gypsum, illite, magnesite, alunite, vermiculite,
aerinite, surite, hematite, silicon oxide, epidote, magnetite, and clay. In addition, the grain–size
distribution for 18 samples of inverted wadis in two localities ranges from (–6 to 4.5 ɸ scale), with
boulders are commonly 1 m in diameter. Lastly, inverted topography on Mars as a landform is
extremely valuable to give us detailed data about paleoenvironmental conditions, including
paleohydrological and sedimentological, this is making it an important candidate sites for landing.

Reflective Essay On Astronomy
The last time I remember learning about astronomy formally was as far back as elementary school,
where we learned about the basics of our solar system's planets and other ideas about space
commonly known by most people. Having never studied astronomy at a higher level, going into this
class felt similar to traveling to a foreign country, or sailing in foreign waters, so to speak. Many of
the concepts and facts have been things I have had little to no prior knowledge of. But regardless of
any of that, I cannot express the importance of this area of study in my life. In the past I have read
comments online, as well as heard things in real life, about how some subjects have no value in
being studied unless one is majoring in them. While my major is not astronomy, much less even
science, I still could not disagree more with this sort of thought. I can relate to some of the concepts
of astronomy on a very deep and personal level, to the point where my psychological state is
affected, and I will explain these thoughts in detail later. While these areas of great interest have not
yet been covered in the course, I cannot say that I have not found all of the current topics
fascinating. As one who has a deep interest in mathematics, I found a few of the concepts rather
thought provoking, and I will again this later. I will lastly discuss what I thought of the material as a
whole, what I got most out of it, and what my experiences were during and after learning it. Out of

A Species of Grass is E. Elymoides
The life form of E. elymoides is considered graminoid, which it is a plant with narrow leaves that
grow out from a base (Simonin 2001). E. elymoides has a height growth between 10 and 45 cm tall
where hollow stems, culms, protrude out from the base of the grass. The leaf blade thickness is
anywhere from flat to curved ranging from 1 to 6 mm; whereas the complete flower head, or
inflorescence of the grass, is a spike ranging from 2 to 17 cm long not counting the bristle–like
structures at the end of the leaf. The internodes on each inflorescence structure are between 2 to 10
mm with branching on each side of the stem. The bristle–like structures that grow out from the
leaves are anywhere from 2 to 10 cm long, and often become purple as the plant matures (USDA
2006). To get a better idea of what E. elymoides looks like, the image below gives you an idea of
what the bristle–like structures look like as well as the size and appearance of the inflorescence.
Furthermore, the awns (bristle–like structures) help protect the plant from getting eaten by grazing
animals because they puncture flesh around the mouth which causes irritation and could potentially
cause eye or ear injury (Simonin 2001).
E. elymoides is able to tolerate moderate fire because of its rough texture, small size, and very little
leafy material that is difficult to catch fire (Simonin 2001). The likelihood for E. elymoides to catch
fire increases as the amount of dead and dry material increases from previous

ferrous and deep/shallow signals.
Archaeological features can be mapped if they have higher or lower resistivity than the surrounding
area. A stone foundation might impede the flow of electricity, while the organic deposits within a
midden might conduct electricity more easily than surrounding soils. Electrical resistivity tests for
the position of low resistivity signals in 2–D. This generally relates to features wider than .5 meters
and deeper than .5 meters.
Gradiometry and magnetometry show the position in 2–D of magnetic anomalies, and relates to
features wider than one meter and 1.5 meters respectively. Magnetic susceptibility shows the
position in 2–D of areas of high magnetic susceptibility. This yields areas of high susceptibility,
which can be expected with occupation. Magnetometers use a single sensor to measure the total
magnetic field strength, or may sue two spatially separated sensors

The Five Pillars of Islam are the framework of Islamic life. First off, a Muslim must have faith in
Allah and believe that there is only one Allah and Muhammad is His messenger. Next, a Muslim has
the duty to pray five times each day, which is considered to be a direct link between him and Allah.
Third, a Muslim must distribute alms and help the needy. Fourth, a Muslim is responsible to keep
the Fast of Ramadan. Lastly, a Muslim is obligated to make a pilgrimage to Mecca in his lifetime.

It is very significant that a Muslim spends a lot time with his family and friends, throughout this
month, and realizes what is truly important in his life. Many more Muslims attend Mosques during
Ramadan because they believe that Allah will help them understand the essentials of life.
Throughout Ramadan all Muslims are strictly obligated to pray five times each day and, in addition,
attend Mosque and have a nightly prayer, called Taraween, which is two to three times as long as the
usual daily prayers. Along with praying, Muslims celebrate significant days in the month. "On the
evening of the 27th day of the month, Muslims celebrate the Laylat–al–Qadr (the Night of Power)"
(Zahid). This night is
Jafari 3 celebrated because it is believed by all Muslims that it was the night that Muhammad first
received the revelation of the Quran and the night when Allah determines the future of the world for
the next year. By celebrating nights like this along with praying at home and in a Mosque, a Muslim
becomes much closer to Allah and in return gets to know their own identity much better. Reading
out of the Quran and worshipping Allah is one of the most important things to do during the Fast of
Ramadan.

Experiment:
Does the length of the candle affect the duration of ignition under the cups of the small size.
OBJECTIVE OF ACTIVITY:
To demonstrate that the length of the candle affect the duration of ignition under the cups in small
size.
DESCRIPTION OF THE ACTIVITY:
The activity will be conducted on candles and cups will be used as models to investigate the process
of ignition.
Experiment will make the students learn three skills categories i.e. observation, questioning and
prediction', 'planning and conducting investigations' and 'data presentation and developing scientific
thinking' in the following way:
The images will graphically illustrate ignition of the candles under the cups and the role of the
length of the candle. From this observation, students make predictions about the duration of the
ignition of the candle depending upon its length. In this experiment, students will ask questions,
conduct an investigation, gather data, and communicate their results. Practice with scientific inquiry
will help students understand the process of ignition of candles and variation in the duration of this
ignition with the variation in size of cups and the length of the candles.

Essay on The Ethics Concerning Space Debris
The Ethics Concerning Space Debris
In more than 40 years of space activities some 3800 launches led to about 25000 observable space
objects larger than 10 cm of which 8300 were still in orbit by September 1997. Only 6% of the
catalogued orbit population are operational spacecraft, while 50% is said to be due to
"decommissioned satellites," spent upper stages, and objects such as launch adapter and lens covers,
which are mission related. The other 44% is originating from 140 on–orbit fragmentations. These
events have been the main source that has generated a population of objects larger than 1cm on the
order of 70000 to 150000.
Efforts to provide a definitive assessment of this problem have been directed toward analyzing the ...

Due to the large number of space exploration projects, a large belt of debris has formed that can be
hazardous to other operational spacecraft. As engineers, we have an ethical responsibility to prevent
pollution of Earth's atmosphere. We have learned a hard lesson on the value of environment from
right here on Earth. Trends show that the debris belt circling the Earth will only get bigger, and
become more hazardous to spacecraft.
There is an ethical issue vs. a legal issue vs. a cost issue that is very much open to debate. Several
decades of space exploration have led to a buildup of non–functional "space junk". However, proper
disposal of equipment is just added cost for a space program that is already on a tight budget. If
space is in fact the "final frontier", then we must learn from our mistakes here on earth and
minimized the contamination and pollution of the space. As engineers, we have a moral
responsibility to do everything in our power to preserve the environment. We are all stakeholder in
this issue because it involves our tax money to fund a lot of these outer space project. But more
important emphazies should be made on precerving and taking good care of the evironment we live
in and the ones we explore such the outerspace. Back
PROBLEM DEFINITION
The space debris population consists mostly of explosion fragments, but also includes operating and
expended satellites; mission–related objects such as shrouds, clamps, and

Essay about Orders of Magnitude and Online Personals Industry
EXECUTIVE SUMMARY 1. The online personals industry took its first breath in 1992. In the
beginning, the industry experienced very slow growth. Nonetheless, by 2005, due to positive
changes in public perception, the industry was booming. By the end of 2007, the industry had grown
to a $900 million market. Observers expect the market size to double by 2012. The industry serves
its customers by enhancing the 'self–actualization' stage of an individual's (Maslow's) 'Hierarchy of
Needs.' It seeks to provide that one–of–kind–product in a way that not only distinguishes the
product but the customer itself. The industry's low customer loyalty rate, high customer bargaining
power, diverse range of substitutes, low barriers to entry and ... Show more content on

Customers "supply" a website with the necessary profile information that helps an online personals
website built the necessary "inventory" of singles which attracts more customers. The structure of
this industry indicates that companies are in a position to manipulate their suppliers; hence, they are
arguably the supplier themselves. Rivalry: Competition in the online personals industry seems to be
quite intense. Rivals can easily replicate a competing firm's technology and claim that their service
is superior to its competition's. Low customer loyalty makes competition even more serious as
companies have to spend a lot of money marketing their service to convey two messages: 1) their
service is better; and 2) their website is the place to find one's soul mate. The lack of focus in
sending one clear message simply adds on to how much these companies have to spend on their
advertising/marketing strategies. Barriers to Entry: A major reason why competition is so intense is
that entering into this industry is relatively easy. Individuals simply need to understand the basics of
creating a website and be able to gain access to enough networks of singles to claim itself as a
player within the industry. Looking at the statics of 'Niche sites' segment of the competition in this
industry illustrates this point: "(There) were at least 850 different

Nature And Magnitude Of Malnutrition In Peru
Nature and Magnitude of Malnutrition in Peru, Including Affected Population
Classified as an upper middle income country, Peru is currently undergoing dramatic changes, and
its recent economic growth has been commendable. These promising indications notwithstanding,
the country is not immune to one formidable challenge of our time–malnutrition–which a great
many countries are subject to. The World Food Programme (2016, para.3) emphasized that despite
the considerable progress being made, Peru is confronted with rampant chronic malnutrition; more
than 5 million people are suffering from a severe food shortage; however, rural women and children
account for a larger proportion of the affected population. The International Fund for Agricultural
Development (2010) mentioned that "most rural women [in Peru] are poor or extremely poor, even
as they play a central role ... Show more content on Helpwriting.net ...
On the one hand, while the country is notable for its social and cultural diversity, it is rife with
gender inequality and abject poverty in which women and their children are predominantly affected.
On the other hand, Peruvian men tend to enjoy economic opportunities. Valdivia (2004, p.489) noted
that two decisive factors–extreme poverty and societal inequality–continue to plague Peru despite
the occasional economic growth of the country in the 1990s. Further, Peruvian women also
experience gender–based violence. Boesten (2012, p.361) stressed that violence transcends domestic
abuse, and many Peruvian government institutions, especially the military, are notorious for gender–
based sexual violence committed against women. On top of that, Peruvian women's education level
indicates that women are more prone to social inequality, thus rendering them more underprivileged
in the society. For example, one out of ten Peruvian women has no education, while the number of
women receiving higher education stands at 20
