Chemical Test Paper
A. There a many different test that are chemical and physical that we could use for our soil sample.
One physical test that can be performed is a particle size distribution of a soil sample. For this test,
you get your sample of soil and place it in a jar. You then add water, a drop of soap, and shake the jar.
After a length of time the contents of soil will develop into layers. You would then see the makeup of
your soil with sand being at the bottom, silt in the middle, and clay at the top. You can then find the
distribution of the soil and determine the soil texture. This soil test could help a cooperative extension
service to determine if they need to add more contents like sand, silt, or clay so it will increase the
growth of plants on that particular area where the soil is growing. A chemical test that can be
preformed is a PH test to get the acidity of the soil. You test this by placing PH paper in soil
concentration and the color change will indicate the PH of the soil. The a high PH shows the level of
the base while the low PH will show how acidic the soil is. This is important to a recommendation
because the PH can affect nutrients, minerals and growth. ... Show more content on Helpwriting.net

One method of conserving soil is terracing.Terracingcreatesdifferentlevelareasona hillside. Steps
would then be created because each level would be higher. This decreases erosion because because
soil barriers are created by the terraces. Another method is crop rotation. This method is when you
rotate crops over time when you are farming. Crop rotation prevents soil depletion, maintains the
fertility of the soil, and minimizes erosion from water by reducing overland

Medical Experiments During The Holocaust
"I will remember that there is an art to medicine as well as a science, and that warmth, sympathy, and
understanding may outweigh the surgeon's knife and the chemist's drug." (Louis Lasagna). However,
the doctors of the holocaust didn't care, and used the victims as guinea pigs for the results. The
medical experiments performed during the Holocaust had horrific outcomes for those experimented
upon. The freezing and hypothermia experiments were tested upon males to test the conditions of the
warriors suffered out in the fields. Tons of German soldiers died of freezing temperatures or were
paralyzed by cold injuries. They only used healthy men in these experiments, though, because the
week men would not be equal to the soldiers. These experiments were split into two parts. One part

Group one received an artificial wound and it was injected with bacteria. Group two got either wood
or glass splinters inserted into their wounds. Last, group three, received both wood and glass
splinters. The last very excruciatingly painful experiment was the interrogation and torture
experiments. These experiments were supposed to test people's limits, endurance, and existence.
They simulated extremely high altitudes with and without oxygen. Theses experiments were executed
in Dachau concentration camp. There were four experiments conducted slow falling with and without
oxygen, and falling with and without oxygen. There were about 200 people chosen for the
experiments, and out of all these people, less than 40 had been condemned to death, but 78 were
killed. To do the experiments they were put in containers that were air tight. Then the pressure inside
the container was changed to simulate the experiment they were assigned to. They figured out that
only continuous experiments at altitudes upwards of 10.5 kms ended in death. They also showed that
the victim stopped breathing after about 30

Variance Is A Statistical Method Used For Test Differences...
Analysis of variance is a statistical method used to test differences between two or more means.
ANOVA is used to test general rather than specific differences among means. An ANOVA conducted
on a design in which there is only one factor is called a one–way ANOVA. The One–Way ANOVA is
considered an omnibus test because it indicates whether or not there are any significant differences in
the means between any of the groups. However, it does not indicate which mean are different. The
One–way ANOVA compares the means of the samples or groups to make inferences about the
population means. The one–way ANOVA, two kinds of variables: independent and dependent. Also,
the one–way ANOVA is used to determine whether there are any statistically ... Show more content

The One–Way ANOVA can compare the means of three or more groups. Furthermore, by running
additional t– tests an increase 5% error increases with every t–test ran. An ANOVA, on the other
hand, has a 5% error, that remains trough the duration of the test. Therefore, if one is running many
controls the type I error remains at 5% and the researcher can be more confident that any statistically
significant result you find is not just running lots of tests.
In a one–way ANOVA, the null hypothesis tested by rather the population means are equal, or that
each of the group means is equal. If the null hypothesis is rejected, then it can be concluded that at
least one of the population means is different from at least one other population mean. The alternative
hypothesis, however, looks to see that at least two of the group means are significantly different. The
assumption of independence is obtained if the observations are random and independent if they are to
be representative of the populations and in no way related or dependent on another. The distributions
of the populations from which the samples are selected are normal; This is commonly referred as the
assumption of normality. The variances of the distributions in the populations are equal. This is often
referred as the assumption of homogeneity of variance.

What Chemicals Are Used And How They Will Be Used
– General
– In this section of the manual, it specifies what chemicals are used and how they will be used in the
lab. They specify that each reagent is to be used within its expiration date, and will not be used past
this date unless there is a legitimate reason for its continued use. It then goes on to specify that all
reagents will follow at least American Chenical Society guidelines for reagent grade chemicals and
what chemicals the lab uses. Finally, all chemicals will be checked prior to any case, recorded in the
case notes and in the Reagent Daily Use Verification Logbook, & will be replaced if the reagent
cannot be used. The new solution of the reagent will be tested and documented in the Latent Print
Reagent Logbook.

This section also specifies that the staff will have a four–year degree from an accredited college or
university with a major in forensic science, criminalistics, or in a physical or natural science, and one
year of professional experience as a Latent Fingerprint Examiner in a forensic laboratory or in an
identification division. However, if the individual has been in the discipline prior to December 2004,
then the educational requirements may be waived. Finally, it specifies that there will be competency
tests to show that the analysts are able to perform the proper test methods, write a report to
demonstrate the proper way of conveying results and the significance of said results, a written or oral
examination to determine the person's knowledge of the discipline, and a moot court to assess the
ability to properly convey and present results of evidence in court. There are cases in which the moot
court would be waived, such as in the case that the analyst is receiving training in additional
categories of testing. The Latent Print Section also keeps and provides access to resources of the
discipline, so the analysts are required to review the literature every three months, and document it.

The Pros And Cons Of Animal Testing
It shows clearly that animal testing is very cruel and inhumane, because scientist force them to eat
and drink just for experiment. "For example: forcing dogs to inhale cigarette smoke did not show a
link to lung cancer; Flossing, an arthritis medication, tested safe in monkeys but caused deaths in
humans; and the recalled diet drug fen–phen caused no heart damage in animals, while it did in
humans––just a small sampling of volumes of examples." (NEAVS–– New England anti–vivisection
society)
Replace animals from experiments doesn't mean that we put human beings at risk also doesn't mean
that medical progress is slow or not develop. Instead, replacing animal experiment will improve the
humaneness of science. According to National Institute of Environment Health Science "We can
replace animals by computer models or cell– based system, for traditional animal's models, or replace
one animal species with a less highly developed one like replacing mouse with worm." We could treat
animal by decreasing pain and distress in animals or enhancing animal well–being. As of now, "China
is the only large cosmetic industry that made 32 billion worth of cosmetics it mandatory for all
products sold in their country to be tested on animals. Where America is making steps in the right
direction to end animal testing all together by beginning to use alternative testing methods that do not
involve animals at all." It's a good start but just doing our self is not enough, we should educate

Pipete Lab
Introduction: In this lab, we used different types of pipettes to measure the volumes of water. The
accuracy of pipetting could be determined by the weight of liquid we dispensed and used it to
compare with expected weight. The purpose of this lab was to use pipets correctly, also increased the
precision and accuracy for the lab demand. Methods and Materials: We used both 5mL and 10 mL
pipettes, a pipette bulb, a 50mL dry beaker, water and scales. We did the experiment for three parts,
we used 5mL pipette twice and used 10mL pipette once. The reason why we did the second time by
using 5mL pipette was to compare the accuracy between two tests. And these three tests were
following the same steps. For the first two tests, we weighed a dry

The video quality evaluation was put forward to the birth of video technology, it is performed to
evaluate the quality of a set of video sequences under study. Video quality can be evaluated by
objective video quality and subjective video quality, the objective video quality can be evaluated by
some parameters of objective video quality classified from the original signal and the received signal,
but we cannot judge the video is good or not, just from some objective parameters. Therefore, it is

However, the impairments that are easily detected by direct differential methods.
SSCQE
The SSCQE is also a family of single stimulus like ACR and ACR–HR. The methods selected a
longer test video sequence which should last at least five minutes, and the audiences continue to
score the observation video sequence. In the end, the staff can get a series of scoring statistics, the
score not only consider the value of the score, but also consider the scoring time.
This test method have a better performance in video quality with time–varying compression system,
in other word, it gives an entire assessment for a longer video sequence.
However, the test video sequence is very long, it results in a problem of the test method that it will
not have reference during the test, thus we cannot remove the impact of scene bias, audiences' feeling
and so on, besides we cannot compare the scores from different SSCQE test experiments for the same
reason, so the result of SSCQE is independently. In addition, the selected test video sequence may
make a huge effect to the final result. Therefore, how to select a comfortable test video sequence
becomes a serious

Read-Recite-Review Study Strategy
An independent variable is a set variable that does not change due to a change in another variable.
The independent variables in the Read–Recite–Review Study Strategy research article were the types
of study methods. The types of study methods were measured as the 3R, rereading, and note–taking
strategies. These strategies did not change and would determine the dependent variables.
The dependent variable is a variable whose results rely on another variable. The dependent variable
in the study was the amount of retained information from each study methods. The amount of
retained information depended on which study method was used. The retained information was
measured by the scores on each test that was taken.
Design & Procedure:
The design of the study was experimental The study was set up to uncover the causal relationship
between study methods and the amount of information that was retained. Participants were randomly
assigned to each of the study methods. The researchers used the type of study method as a potential

The 3R method was beneficial towards immediate and delayed recall in Experiment 1. The mean
correct performance in Experiment 1 showed better test scores in free recall and short answer testing
when using the 3R method compared to the other methods. In Experiment 2, the 3R method increased
scores for multiple–choice and problem solving tests. Experiment 2 also showed 3R being the most
beneficial in retaining information. The participants' results on delayed testing were higher on each
test than any other study method. Thus, the benefits of 3R go beyond boosting performance on a
criterial test that parallels recitation (McDaniel, Howard, & Einstein, 2009). Both studies concluded
that testing over material improves long–term learning and retaining

Since this graph does not show any outliers, I thought that the line of best fit should be polynomial
since the polynomial curve. I think this because the curve passes through most of the data points and
is the closest R2. These are a bigger difference in the value of 0,02 cm and 0,04 cm. I think this
happened because the holes that were being blocked by the overlapping of the cloth in value 0,04
were more than in the value of 0,02 cm. The more holes getting blocked by the overlapping of the
cloth will cause the light to not be able to pass through which then causes the results to be low. This
is a pattern that we also can see. Starting form value 0,04 to 0,10 then results do not have as big of a
difference as 0,02 and 0,04

thumb, this is important as it includes the skin and fat of the athlete. Then use the callipers one
centimetre from the fingers at a depth equal to the thickness. Record the same area of the body three
times and then take an average of the three by dividing the total of the number by three. Getting an
average will make the results more reliable.

Although there Is only one piece of equipment needed to record data, the callipers are not something
you find in the super market. Due to the unique nature of the callipers it may be hard for schools to
purchase large amounts of them due to cost and availability, this is negative as it means that the
school or a specific class cannot do the test as a group so difficulties may arise such as incorrect
readings or incorrect methods being used. Another disadvantage with the equipment would be that if
a small number of callipers can be brought then a glass may struggle to complete the test as the time
taken up by only having one set if equipment between a class will be elongated and may cause
students missing out on doing the test.

Non Greasy Pastes As Semisolid Dosage Form
Based on United State Pharmacopeia, pastes are defined as semisolid dosage forms that contain one
or more drug substances intended for topical application. (Pharmaceutical Dosage Form, 2009) Pastes
are intended for application to the skin, oral cavity, or mucous membranes. Pastes are usually
prepared from fats, fatty oils, petrolatum, paraffin, waxes, glycerin or water by mixing
homogeneously powdered drug with the foregoing materials as bases. (General Requirements for
Pharmaceutical Preparation) There are two classes of paste which are fatty pastes and non–greasy
pastes which is made from single phase aqueous gel.
Although the preparations of pastes are similar to ointment, there are still having differences between
paste and ointment. Compared to ointments and gels, pastes contain a high proportion of finely
powdered medicaments. Pastes are generally composed of ointment bases that contain a high
concentration (frequently 50%w/w) of dispersed drug. Hence, the viscosity of pastes is higher than
that of pharmaceutical ointment. The base for pastes may be anhydrous (liquid or soft paraffin) or
water soluble (glycerol or a mucilage). (Prashant, 2010)
Furthermore, pastes take some advantages over the ointments. Pastes are more often used for
protective action compared to ointments. This is because pastes ordinarily do not flow at body
temperature so it can serve as protective coatings. Fatty pastes that have a high proportion of
hydrophilic solids are less greasy and more

Theranos : A Medical Laboratory And Health Service Company
Theranos Wingho Chan Professor Jacob Robbins Business Communication Drexel University
03/12/2015 Abstract Theranos is a medical laboratory and health service Company that is based in
California. The company was established in 2003 by a young lady by the name Elizabeth Holmes
who had the passion of transforming the health care industry to better. The main focus of the
company was to decrease the size of small blood sample that is taken out of the patient. The company
developed a method where a drop of blood was the maximum size of the blood sample that was used
to give many results. This means that the blood sample is a drop of blood that is taken out of figure
and the patient is supposed to give out the blood only ones because the drop of blood is used in all the
other testing irrespective of their number. On top of that, the company has improved on the efficiency
of its operations, it has reduced the cost of blood test dramatically and it has made the blood test
process to be faster. Introduction A recent survey on medical care indicated that 30 percent of the
people fear to attend hospitals despite their illness because of big needles in the hospitals and the
amount of blood that is drawn out of their body in case of blood test. Theranos medical laboratory
health Service Company has brought to an end this problem. Theranos is a medical laboratory
company that is based in California. The company was established by a young lady by the name

prevalent in animals, such as major types of heart diseases, different cancers, HIV and more

immune system, in an attempt to mimic human diseases. The fact that animals cannot get said
diseases, greatly affects the outcome in humans ("Arguments against animal testing", n.d).

You are in Sephora and the most beautiful eyeshadow is there, but notice it is one of the many brands
that test on animals. You keep picturing the poor bunnies, kittens and puppies stuffed in cages
starving or force–feed to so much they cannot move. The sadness in their eyes, the multiple surgeries
and tests they must go through on a daily basis. Animal testing is not, but should be a banned form of
commercial and scientific testing. In a world as advanced as ours, animals should no longer be the
test subject because it is no longer an ideal method. There are countless other effective methods of
testing these products that do not involve harming anything. The animals chosen for the testing are
all–around different from the human species. The use of animals costs much more than its equally
effective counterparts. Testing harmful products on helpless animals is inhumane and cruel.
Firstly, performing these harmful tests on animals is an old–fashioned method, because society has
many not cruel alternatives. It is commonly confused that the Canadian government claims that a
product has to be tested on animals to release, but this is completely false. "Canada's Food and Drugs
Act prohibits the sale of any cosmetic containing harmful ingredients or contaminants, but does not
require that animal testing be conducted to demonstrate safety,"( Cosmetic Testing in Canada) which
means that any other form of non–animal testing is valid. There are many accepted methods that do

There were two variables installed, one of which focused on a photo stimuli and the other using a
phrase provision, wherein the students that contributed happened to have gone through multiple tasks
that led to them gaining hidden information. Using something called probe study, the students were
then randomly assigned either levels of constraints in which they enacted upon the tasks at different
intervals and sessions using something called familiar or unfamiliar methods. As stated earlier,
multiple probe methods were used during the tests varying in degree to the order in which
participants went through the tasks. The students, 36 of them, went through photographs of faces on
the photo constraints and a couple were chosen at random to observe said faces in a limited amount
of time. After the observations were over, the students were asked questions regarding the faces
they've seen, specifically any changes in mood and facial structure. As the start of the procedure, this
portion was done so multiple time in reordered sections so as to remove any validation issues, and
then moved on to a rating section wherein they scored the faces based on looks. In the second
constraint, the rest of the participants worked on different words and, like the earlier photo variable,
there were students picked at random to participate in a smaller probe in which they were revealed
particular words and asked to memorize the order in which they were given out. They

360–Degree Feedback Scenario 360–degree feedback also known as multi–rater feedback is a
performance evaluation test where employees get anonymous feedback from their co–workers.
Employees can recognize their strengths and weaknesses though this method of assessment. The
paper will look at the mistakes that people make in formulating a 360–degree feedback and
appropriate use of the 360–degree performance evaluation test. Scenario 1 For a 360–degree
feedback to be effective and efficient as a performance appraisal test, managers should be able to
invest time in the development process of the assessment, analysis of data collected (Campion,
Campion, & Campion, 2015). In this ... Show more content on Helpwriting.net ...
Employees can be sensitive to the pressures of the managerial positions and due to biases or the
influence of the recency effects they can fail to consider the period that they being evaluated. Wilson,
2014, suggests that the participants must undergo training to have a credible 360–degree test. In the
above scenario, there might be cases of biases among the top official; some feel that they do not want
to fail each other. Though the management has identified that there are discrepancies in the leadership
skills the results state otherwise. Therefore, such situations can occur in this type of test because of
people might also offer comments that favour all the supervisors.
Scenario 3
The multi–rater feedback is a tool that people to acquire rich, accurate perspective on how others see
the management practices, effectiveness and interpersonal designs (Taylor, Chappelow, & Fleenor,
2008). It is meant for performance. Int the above scenario, the firm's primary objective was to
improve the competitiveness, that decision to undertake the 360–degree feedback just because they
come to a realization that leadership skills and communications patterns are the primary cause of the
less nature of competitiveness is not the ultimate solution. Multi–rater test that managers perform to
change the performance level of the workers can affect the objectives of the organizations. Hence,
some goals cannot be accomplished. For a manager to

Performance On Immediate Retention Tests
Roediger & Karpicke (2005) predict that performance on immediate retention tests would rise with
the number of study opportunities, due to massed practice usually only producing short–term results.
They also believe that taking a retention directly after a study session would result in superior
retention on delayed tests compared to repeatedly studying the material. This would result in proving
that test taking as a better means to improve long term retention compared to re–presentation of
material during testing.
Methods
In order to obtain this information on retention two experiments were conducted using psychological
testing to collect data (Weiten, 2014). The first was a experimental 2 x 3 factorial design, using one
hundred twenty undergraduate students from Washington University, ages 18 to 24 (Roddiger &
Karpicke, 2005). The independent variables that were manipulated were the different learning
conditions and time between studying and test taking, as well as when the subjects would take the
final retention test which occurred either 5–minutes, 2–days, or 1–week after the end of the 1st phase

What Is Three Materials In Use For Hip Protective Padss?
Three materials, either in use for hip protective pads or with plausibly suitable characteristics, were
selected for evaluation. The first material was 3D vertically lapped nonwoven fabric; the second
material was the same, but with its upper and lower surfaces covered by single layers of jersey–
knitted fabric. The third material was polyurethane closed–cell foam that was claimed to be suitable
for hip protective pads by the manufacturer. The mean values of experimental pads' thicknesses were
14.16 mm, 15.77mm and 15.89 mm respectively.
The fabric for pocket assembly was made of 92.35% :7.65% cotton elastane . The mean value of wale
density was 15 wales/cm and mean valueof course density was 25 courses/cm. The mass per m2 of
fabric was ... Show more content on Helpwriting.net ...
It had density of 1.1 kg/m3 and shore A hardness of 12, the same properties as the artificial flesh used
in previous hip protector testing (Derler et al., 2005). Its thickness of 20 mm corresponds to the
typical thickness of soft tissue found over the most prominent part of the greater trochanter in female
hip fracture patients (Lauritzen and Askegaard, 1992). The artificial flesh (and the fabric specimen
size) was 5 cm × 5 cm, derived from the 5 cm diameter of the average female femur head (Derler et
al., 2005, Mall et al., 2000) and the vulnerable area that projects over the femur (Choi et al., 2010).
The tower with a dropper was placed above the load cell, as shown in Figure 1. The desired impact
energy of the dropper was obtained by varying its falling height. The impact force the dropper
transferred to the experimental pad was captured by the load cell, which was connected to an Arduino
circuit board to record the data. The data was then transferred to a computer using Bluetooth.
According to Robinovitch et al. (2009), typical speeds of person fall are 2.0 m/s for a mild fall, 3.4
m/s for a moderate fall and 4.5 m/s for a severe fall. The kinematic equation for free fall is illustrated
below.
V2 = 2gh (1)
Where V is speed (m/s); g is gravity (m/s2); h is height (m).

that you can see the best. Method: 1. Place a stencil over your material 2. Paint over the stencil 3.
Leave material to dry 4. Wash stencil and repeat with other colours. Results: As I suspected, you
couldn't see experiment C at all. Experiment A did turn out, but it turned a more dirty red/brown
colour than a bright red. Finally, I believe experiment B turned out the best as the blue clearly
showed. Conclusion: I will be using experiment B, as it came out the brightest and I don't mind how
the picture looked patchy. Modifications: As the original stencil I used to experiment was ruined, I
will be changing the stencil I use for my final piece. Experiment 2 Aim: ... Show more content on

Place boning in the middle of the seam. 3. Sew the edges of the covering of the boning onto the seam
allowance. Results: Experiment A did not work for me at all, as I did not line up the seam and the
boning properly. Experiment C work really well and so did experiment B. Although the boning for
experiment B seams stronger than the boning for experiment C. Conclusion: I will be using
experiment B as it worked well when tested and it seems stronger than the other two experiments.
Experiment 4 Aim: To Test which colour thread I like for my lazy daisies. Method: 1. Sew a lazy
daisy stitch with a certain coloured embroidery thread. 2. Repeat with other colours. Results: I did not
like how colour C turned out against the red material. As I will be using colour B (black) for my
machine embroidery I will not use it for my hand embroidery as I believe it would turn out better if I
had a contrast between two colours on my corset. Conclusion: I will be using colour A, as I would
like to have the contrast of the white and the black, (which I will be using for my machine
embroidery) Modifications: For these experiments I used 6 threads for the lazy daisy stitch, but for
my corset I will be using only 3. Experiment

Ld50 Correlative Model
LD50 or the lethal dose of 50%, is the amount of a chemical which kills 50% of the population of a
test species (used in toxicity evaluations) exposed to that. The EPA study used IC50 toxicity data of
selected chemicals towards HeLa cell lines to predict their in–vivo (LD50) toxicity values. IC50 is an
index of the toxicity of a substance defined as the concentration of that chemical which have
inhibitory effects on the growth of the 50% of the test population. HeLa cell used in this study is an
immortal cell line, which is the oldest yet most commonly used human cell line for scientific
research.21 In the next step, we explain how LD50 data predicted from the EPA's correlative model
can be further used to estimate the human health impacts

Daphnia Magna Experiment
Methods: To begin the experiment, we took a single Daphnia magna from the unused tank to run
control tests with distilled water on the untampered heart rate of the species. The species was placed
on a concave slide with a new drop of water on it. It was given 2 minutes of recovery time to adjust
to its new environment; then, the heart rate was studied by intervals of 15 seconds to find beats per
minute by multiplying the number of beats in 15 seconds by 4. The Daphnia magna was studied
under a light microscope with 40x total magnification. After each round of data collection, the water
was absorbed with a Kimwipe so a new water drop could be placed on the species. The same Daphnia
magna was used for six rounds of control experiments. After

Persuasive Essay On Animal Rights
Mahatma Gandhi once said, "The greatness of a nation and its moral progress can be judged by the
way its animals are treated." The social issue of animal rights first arose in the 1970s; since then the
animal rights movement has gained momentum and a considerable amount of followers "Animal
Rights." Organizations like PETA (People for the Ethical Treatment of Animals) hold demonstrations
and protests in the streets and outside businesses to denounce the maltreatment of animals. There are
two sides on this issue, those who believe that the life of an animal is inferior to that of a human's and
those who deem that animals deserve to have a life free of human interruption "What Are Animal
Rights." Without animal rights, our society can be deemed unfettered by empathy and restrained by
immoral values.
To begin with, why support animal rights? Some people are not joining the animal rights movement
frankly because they are not informed and up to date with the controversy. The general public is
aware of the animal testing taking place in labs daily. Adopting this strategy was an effortless
decision as it produced results and did not put the lives of other humans in danger. However, the
public isn't aware that the results provided aren't always guaranteed to be reliable and that animals
sometimes suffer slow, painful deaths as a result of these experiments. Our society holds gruesome
double standards, we would not dare think about holding experiments on our loved ones, so why do
we

Disadvantages Of Completely Randomized Design
The treatments that are assigned completely at random so that each experimental unit has the same
chance of receiving any one treatment is known as, a Completely Randomized Design (CRD). It is
assumed that all experimental units are uniform. Any difference among experimental units receiving
the same treatment in the CRD is considered as experimental error. Thus, Completely Randomized
Design is suitable just for the tests involving homogeneous experimental units, for example, lab
research, where ecological effects are generally easy to control. The CRD is the simplest of all
designs. The replications of treatments are assigned completely at random to independent
experimental subjects. It is equivalent to a t–test when only two treatments are ... Show more content
on Helpwriting.net ...
If experimental error is heterogeneous, valid comparisons can still be made.
However there are also few disadvantages of Completely Randomized Block Designs, which are
1. It is not suitable for big number of treatments because blocks become too big.
2. It is not suitable when complete block contains considerable variability.
3. Error df is smaller than that for the CRD (problem with a small number of treatments).
4. If there is a large variation between experimental units within a block, a large error term may result
(this may be due to too many treatments), as interactions between treatment and block effects
increase error.
5. If there are missing data, a CRBD experiment may be less efficient than a CRD
Appropriate use of Completely Randomized Block Designs
It is suitable to use it when there is a known or suspected source of variation in one direction.
Orientation of the blocks to have minimum variation within the block and orientation plots to sample
the entire range of variation within the block.
The CRBD is one of the most widely used designs. If it will control the variation in a particular
experiment, there is no need to use a more complex design. The most important item to consider
when choosing a design is the uniformity of the experimental

Vibration Test of Composite Materials on the Basis of...
Vibration test of composite materials on the basis of measurement of dynamic properti
INTRODUCTION
On the basis of measurement of viscoelastic and dynamic properties, there are four important
parameter such as damping, relaxation, creep, and strain rate, which describes evidence of
viscoelastic behavior and can be calculated with the help of an experiment, but this paper describes
the method of test for the measurement of damping. In addition, the notation of complex modulus
describes conventionally for damping and dynamic stiffness of linear viscoelastic materials, where
the methods of vibration test are considered for measurement of complex moduli of composites. With
the help of this test of plates and beams to find dynamic elastic moduli also get evaluated.
In vibration test, notation for complex modulus is suitable for portrayal of dynamic behavior of linear
viscoelastic composites. The damping and stiffness which are the constituent part of the complex
modulus are belongs to the dynamic mechanical properties, which may be measured with the help of
experiments with vibration and wave propagation experiments ,and the measurement of the same is
considered for dynamic mechanical analysis.
However, there are many traps with respect to the different kind of techniques which must get
avoided. In example, there was a development of commercial dynamic mechanical analyzers for the
testing of small specimen of unreinforced low modulus polymers, and stiffness is generally

Red Blood Molecules Permeability Lab
The purpose of this lab was to understand the effect of molecular size and polarity on the ability of
certain molecules to pass through the membrane of red blood cells. The lab involved a series of
propanol test solutions containing 4 mL of 0.3M propanol, propanediol, or propanetriol, and 12 mL
of bovine blood. The test tube was held up in front of a slit lamp to measure the hemolysis time of the
bovine blood. The slit lamp consisted of a light source positioned behind a piece of cardboard with a
hole in which a thread was suspended. The light from the lamp illuminates the culture tube, allowing
the thread to be seen once hemolysis occurs. The results are shown in Figure 1. Hemolysis is the
breaking apart of blood cells due to their hypertonic environment which causes the extracellular
solutes to diffuse into the cell, in turn, results in swelling of the cell and eventually cell rupture.
Molecules primarily cross cellular membranes by three methods; those being through lipid bilayers,
aqueous channels, and carrier channels. The size, polarity, and charge of a particular molecule have a
direct effect on the rate of diffusion of that molecule. As it relates to the diffusion of propanol, the
number of hydroxyl groups within the molecules increased which caused the polarity of the to
increase, which also ... Show more content on Helpwriting.net ...
Propanol, propanediol, and propanetriol all have different amounts of hydroxyl groups: one, two, and
three in their respected order listed. Therefore, the propanol with the most hydroxyl groups,
propanetriol, caused hemolysis to occur slower as the molecule is larger and more polar than the
others. This is evident in figure

Pros And Cons Of Animal Testing
An animal test is any scientific experiment or test in which a live animal is forced to undergo
something that is likely to cause them pain, suffering, distress or lasting harm. As right now, millions
of mice, rats, rabbits, primates, cats, dogs, and other animals are locked inside barren cages in
laboratories across the country. They languish in pain, suffer from extreme frustration, ache with
loneliness, and long to be free. The complete lack of environmental enrichment and stress of their
living situation cause some animals to develop neurotic types of behavior such as incessantly
spinning in circles, rocking back and forth, pulling out their own fur, and even biting themselves.
They shake and cower in fear whenever someone approaches, and their blood pressure spikes
dramatically. After enduring a life of pain, loneliness, and terror, almost all of them will be killed.
There are many non–animal test methods that can be used in place of test on animals. Not only are
these non–animal test more humane, they also have potential to be cheaper, faster, and more relevant
to humans. Some of this methods are non– invasive imaging techniques such as MRIs and CT scans,
computer models and simulations, and stem cell and genetic testing methods. Some of the
experimentations conducted on animals today is required by law, most of it is not. In fact, a number
of countries have implements bans on the testing of certain types of products on animals, such as the
cosmetics testing bans in

Paper Towel Experiment
Abstract: The overall question that was trying to be answered during this experiment was: Which
paper towel brand is the strongest? Before completing the experiment, the hypothesis was that out of
Bounty, Brawny and Sparkle, Bounty would be the strongest paper towel. This was because on
reviews for paper towels Bounty was almost always rated five stars, while Brawny and Sparkles had
lower ratings. To test this experiment, the first steps were to fill a container with water, and lay a
paper towel in it. Next steps were to let the paper towel soak up the water for five minutes, and then
take it out of the water when the timer went off. Final steps were to stack quarters on the center of the
paper towel ... Show more content on Helpwriting.net ...
These steps would be repeated for all three paper towel brands. At the end of the experiment, the
paper towel that held the most quarters would be the strongest. Data for experiment still needed to
give a conclusion to project.
Introduction: Every paper towel brand claims to be the best, but which brand is actually the best? The
purpose of this experiment was to test the strength of multiple paper towel brands to see which was
the strongest. This information is useful to know because most people buy paper towels, and would
like to get their money's worth. Many websites that had reviews on paper towels had Bounty rated at
a five star. This leads many people to believe that Bounty is the best paper towel brand, but doing this
experiment was the true test to

The Perfect Opportunity For Learning
have an opportunity to talk about their ideas. This discussion is the perfect opportunity for learning to
happen. According to Stevens and Slavin (1995) "cognitive apprenticeship" is elaborated in that,
students of different levels of achievement work together to learn. Students with higher–level
academic abilities are able to use their own understanding to explain to the other students, whereas,
the lower students are able to use the explanation from their fellow classmates to understand the
material. Cooperative learning is not always viewed looked as the best teaching method.
Other researchers have shown a disadvantage in group work with regard to teaching students. Slow
learning students may lag behind due to their passive nature or lack of confidence (King, 1993).
When the quick learning students dominate the group and discussions, the lower achieving students
may not feel open and free to contributing in the discussion. In this case, the learning opportunity
could pass them by without anyone noticing the lack of understanding. Other limitations of
cooperative learning is the time required for some groups to work in unity and unable to teach the
curriculum in a small group Cooperative Learning setting (Good, Reys, Grouws, & Mulryan,
(1989;1990).
2.2 Related Research When referring back to the topic of cooperative learning technique, a lot of
efforts and steps were taken throughout the previous years, and there are still a lot of works that can
be done on it too.

Nitrophenol Lab
Method The first portion of the lab was about preparing the standard curve for the reaction products.
In this part we already know the concentration of the product, Nitrophenol. So, to perform this we
took six test–tubes and filled each with 1ml of standard labeled with S1–S6 respectively. For example
1st =S1, 2nd=S2, 3rd =S3 and so on. After that we measured the absorbance of each test tubes setting
the first one as blank. And the data is recorded in the table (5.1). After recording the reading we
constructed a Nitrophenol Standard curve by plotting A410 on y–axis and concentration on the x–axis
as on figure (5.2). The second portion require us to prepare acid phosphatase from the wheat germ

With respect to the time mentioned on the laboratory paper we transfer 0.5ml of the solution from the
solution from A to (A1–A6) and B to (B1–B2). After doing that we simultaneously measured the
absorbance using the photo spectrophotometer. The reading are recorded in the table (5.3) and with
the help of this readings we plotted graph which is shown in the figure (5.4). The fourth step of the
experiment was to determine the Vmax and Km for the acid phosphatase. In this part we first look at
the graph from part three of this experiment which is the nitro–phenol standard curve which is on the
figure (5.2). And have chosen the points which were falling on the trend line (slope). After that we
took seven test–tubes and added 1ml of substrate which was already prepared by the instructor in
each of the seven test–tubes. And to that we added 50µL of purified acid phosphatase (125µg) to each
tube at 30 second intervals to stop the reaction. After the end of 2.5min, we added 1.5% (w/v) KOH
to each test tubes at 30 seconds intervals to stop the reaction. After completing this step we used
nitro–phenol standard curve to quantify the concentration nitro–phenol produced

Discretionary Accruals Model
Literature Review of Discretionary Accrual Models Chenxi Lin 01/03/2015 Literature Review of
Discretionary Accruals Models Audit quality is crucial for financial statements users and efficient
capital markets. However, how to measure audit quality properly has been a controversial issue,
because quality is not observable. With no uniform definition of audit quality, prior researchers
developed various audit quality proxies. Earning quality is one of the most commonly used measure
for audit quality. Client discretionary accruals, meet or beat earnings target, and likelihood of
restatement are all under this category. Among those, discretionary accruals are the most widely used,
because it is positively related to earnings management, which reflects audit quality. The purpose of
this review is to summarize the most commonly used models to measure discretionary accruals by
previous literature, and to help future studies to choose from these models when they are used as
audit quality proxies. Among all the research papers, there are two main methods to calculate
discretionary accruals: change dependent variables to accruals model (e.g., Jones Model, Modified
Jones Model, and McNichols Model) and performance adjustment measure (Kothari, Leone, and
Wasley, 2005). The most frequently cited model of discretionary accruals model is Jones (1991)
Model. The estimation of the discretionary accruals was used as the measure of earnings
management. Jones (1991) measured the total

Goldfish Metabolic Rate Lab Report
The null hypothesis for this experiment is that there is no statistically significant relationship between
the metabolic rate of goldfish and their exposure to light. The alternative hypothesis is that goldfish
exposed to ambient light will exhibit a higher metabolic rate compared to goldfish that are exposed to
dark light.
Results
Overall 86 goldfish (N=43) were used in the experiment. Altogether, 43 trails (2 fish per trial) were
conducted in order to track the metabolic rates of the fishes. Differences in metabolic rates (with
respect to light exposure) were calculated by measuring the changes of oxygen concentration in the
water chambers where the fishes were placed. The change in oxygen consumption averaged
445(mgO_2)/(hr∙Kg) when the fishes were exposed to ambient light and 377(mgO_2)/(hr∙Kg) when
the fish were exposed to dark light. Across the trails, the average oxygen consumption as oxygen lost
per hour per ... Show more content on Helpwriting.net ...
For the most part, goldfish exposed to ambient light experienced a higher change in oxygen
consumption than fishes that were exposed to dark light. However, because the p–value for our
experiment, 0.211, fell below the recommended 0.05 threshold, we were unable to report a
statistically significant difference in the metabolic rates of goldfish exposed to different lighting
conditions (ambient vs. dark). Because it is likely that the differences in average oxygen consumption
between the two conditions (exposure to ambient light vs dark light) were a result of chance, we were
unable to reject the null hypothesis stating that there is no statistically significant relationship
between the metabolic rate of goldfish, and its exposure to light. With this being said, previous
studies have reported exposure to light to be an important factor governing the biological cycle of
fish (Choi et al. 2017; Bromage et al.

Persuasive Essay On Why Animal Testing Should Be Banned?
Imagine you are in Sephora and you notice your favourite brand of eyeshadow. However, you also
notice that it is one of the many makeup brands that test on animals. You keep picturing the poor
bunnies, kittens and puppies stuffed in cages starving or force–feed so much they cannot move. The
sadness in their eyes due to the multiple surgeries and tests they are surviving. Animal testing is a
form of commercial and scientific testing that should be banned. In a world as innovative as this one,
it is unfair to have animals endure the test of drugs and other products for the benefit of humans.
There are countless other effective methods of testing these products that do not involve harming
living beings. The animals chosen for the testing are all–around different from the human species,
making them not as accurate resulting in their danger for little to no reason. The use of animals costs
much more than its equally effective counterparts. Testing harmful products on helpless animals is
inhumane and cruel.
Firstly, performing these harmful tests on animals is an old–fashioned method, because society has
many cruelty–free alternatives. It is commonly confused that the Canadian government claims that a
product has to be tested on animals to release, but this is completely false. "Canada's Food and Drugs
Act prohibits the sale of any cosmetic containing harmful ingredients or contaminants, but does not
require that animal testing be conducted to demonstrate safety,"( Cosmetic
