You are examining a copolymer for it\'s potential as a material for a vascular graft. you are trying to determine whether you want a high or low degree of crystallinity in the material. what type of structures for copolymers have a higher probability for crystallization? Solution Answer: Copolymers are formed when two or more different types of monoers polymerize in a process called copolymerization. A block polymer is formed by the copolymerization of different copolymerized monomers. The first component is styrene followed by methyl methacrylate which forms at the end of polystyrene chain. Alternating polymers have regular repeating units of two different monomeric units. Block and alternating polymers can form long range repeated, ordered structures and thus have a higher affinity for crystallization..

In a classic study of blood types in Italy, Dr. Luigi Cavalli sfo.pdf
In a classic study of blood types in Italy, Dr. Luigi Cavalli sforza (1969) found that small,
isolated towns in mountain regions had reduced genetic diversity within populations, but showed
significant genetic differences from one town to the next. In valley regions with more movement
of people from place to place, he found more diversity within the population of any given town,
and fewer differences between towns. If you consider your genetic simulation to represent one
mountain town, and other lab groups to represent different mountain towns, can you explain
Cavalli-Sforza\'s results? How could you alter this lab procedure to simulate what happens in the
valley towns?
Solution
The genetic history of a group of populations is usually analyzed by reconstructing a tree of their
origins. Reliability of the reconstruction depends upon the validity of the hypothesis that genetic
differentiation of the populations is mostly due to population fissions followed by independent
evolution.
Most patterns found in the analysis of human living populations are likely to be consequences of
demographic expansions, determined by technological developments affecting food availability,
transportation, or Military power. During such expansions, both genes and languages are spread
to potentially vast areas.
The first tree of evolution based on gene frequencies of living humans was published 34 years
ago. It was based on genetic distances among 15 populations, 3 per continent, calculated from 5
blood groups, with a total of 20 alleles. The number of genes used was admittedly small, but it
was practically impossible to get more information at that time.
The most important difference is in the position of Europe, which with neighbor joining branches
out first after the splitting of Africans and non-Africans and with maximum likelihood is the last
but one..

For some DNAs it is possible to separate the two strands, after dena.pdf
For some DNAs it is possible to separate the two strands, after denaturation, in a CsCl gradient.
Part A What property of any DNA determines where it will band in a CsCl gradient? density,
charge. polarity. solubility
Part B What kind of DNA might have two strands that differ sufficiently in this property that
they could be separated after denaturation?
UT-rich DNA, GC-rich DNA, AT-rich DNA, AC-rich DNA
Solution
PART A: Density
The experiments done by Meselson and Stahl’s supported the model of semiconservative
replication of DNA. In their experiment, they obtained heavy DNA and light DNA by growing
Escherichia coli (E. coli) bacteria with a radioactive nitrogen isotope 15N, and the more common
isotope of nitrogen 14N respectively.
In the present experiment, the bacteria grown in 15N medium were allowed to grow in 14N
medium. Then the cultured bacteria were taken and the isolated DNA was dissolved and
centrifuged caesium chloride solution (CSCl). Now, the concentration gradient is established in
the test tube, and the DNA molecules move according to the gradient until they reach an
equilibriumdensity with the solution. DNA with 15N strand is heavier than the DNA with 14N
strand, so it reaches the bottom of the test tube.
PART B: GC-rich DNA
GC rich DNA contains high density, which also has high melting point..
Explain how stem cells obtained from IVF leftovers and somatic cell .pdf
Explain how stem cells obtained from IVF leftovers and somatic cell nuclear transfer differ in
terms of the sources of their genomes.
Solution
Oocytes from women were extracted and inseminated with thaed donor sperm, after the process
of insemination oocytes were successfully fertilized and developed into blastocyst stage and the
inner cell masses of the blastocyst that were removed yielded stem cell lines. From a left over
IVF, extraction of single blastomere is helpful.
In somatic cell nuclear transfer, the nucleus of a somatic cell is transferred to the cytoplasm of an
ennucleated egg which then becomes a zygote and is then allowed to develop to blastocyst stage.

In 1865-86, the U.S. was in a dilema. The Civil War was over. President Lincoln was dead. And
the nation was beginning to face a series of unanswerable questions in the after result of the Civil
War like:
How does the U.S. answer the Declaration of Independence’s call for equality?
How does the country define what it means to be a U.S. citizen?
How broadly should the right to vote be like?
And what role should the federal government play in protecting the civil rights of all?
These are the some of the questions raised post Civil War after Lincoln\'s death. In answer to
them the FED Govt led by President Andrew Jhonson of republican party gave a speech in 1866.
The major part of his speech was indicating some enormous changes in constitution of U.S by
the results of Civil War.
As a result of this U.S \'s first Civil Rights bill passed on APR 1866 along the amendments in the
constitution took place (13,14,15th ) which was termed as Second Founding.
I do think it is necesarry to bring some social equality in the times .As many years the Slave
System was in act in U.S and it is one of the Sparking cause for the Civil War.

Construct a java method. This method chooses the number of sti.pdf
Construct a java method.
* This method chooses the number of sticks to pick up based on the
* sticksRemaining and actionRanking parameters.
*
* Algorithm: If there are less than Config.MAX_ACTION sticks remaining
* then the chooser must pick the minimum number of sticks (Config.MIN_ACTION).
* For Config.MAX_ACTION or more sticks remaining then pick based on the
* actionRanking parameter.
*
* The actionRanking array has one element for each possible action. The 0
* index corresponds to Config.MIN_ACTION and the highest index corresponds
* to Config.MAX_ACTION. For example, if Config.MIN_ACTION is 1 and
* Config.MAX_ACTION is 3, an action can be to pick up 1, 2 or 3 sticks.
* actionRanking[0] corresponds to 1, actionRanking[1] corresponds to 2, etc.
* The higher the element for an action in comparison to other elements,
* the more likely the action should be chosen.
*
* First calculate the total number of possibilities by summing all the
* element values. Then choose a particular action based on the relative
* frequency of the various rankings.
* For example, if Config.MIN_ACTION is 1 and Config.MAX_ACTION is 3:
* If the action rankings are {9,90,1}, the total is 100. Since
* actionRanking[0] is 9, then an action of picking up 1 should be chosen
* about 9/100 times. 2 should be chosen about 90/100 times and 1 should
* be chosen about 1/100 times. Use Config.RNG.nextInt(?) method to
* generate appropriate random numbers.
*
* @param sticksRemaining
* The number of sticks remaining to be picked up.
* @param actionRanking
* The counts of each action to take. The 0 index corresponds to
* Config.MIN_ACTION and the highest index corresponds to
* Config.MAX_ACTION.
* @return The number of sticks to pick up. 0 is returned for the following
* conditions: actionRanking is null, actionRanking has a length of
* 0, or sticksRemaining is <= 0.

Solution
1. The monosaccharides are the simple sugar molecules with general formula (CH2O) n. They
are mainly composed of Carbon, Hydrogen and Oxygen. Monosaccharides possess functional
groups such as aldehydes and ketones in their structure. Basing on the functional group present
they are named as aldose - that contains an aldehyde group, ketose - that contains a ketone group.
They also contain many hydroxyl groups. Hence, monosaccharides are called as polyhydroxy
aldehydes or polyhydroxy ketones. A Hexose having ketone group is known as Ketohexose.
Fructose is an example of ketohexose. . Hexose with an aldehyde group is called as Aldohexose.
Example of an Aldohexose is Glucose.
A Triose is a monosaccharide having three carbon atoms in its skeleton. Glyceraldehyde is an
example of a triose.A Pentose is a monosaccharide having five carbon atoms in its structure.
Ribose is an example of a pentose. Both triose and pentose are monosaccharides differing in
number of carbon atoms in their skeleton.
The molecules having a Carbon atom bonded to four different functional groups are called
‘chiral molecules’. The center carbon atom is called chiral carbon. Any molecule having a chiral
carbon exists in a pair of enantiomers, which are nonsuperimposable mirror images. Stereo
isomers are the molecules having same molecular formula and same bonding but differ in spatial
arrangement of atoms. They are mirror images. They rotate the plane polarized light either to
clockwise or to counter clockwise. If they rotate the plane polarized light to clockwise, they are
called as ‘dextro rotatory’ (D forms) and are indicated by (+) sign. If they rotate the plane
polarized light to counter clockwise, they are called as ‘levo rotatory’ (L forms) and are indicated
by (-) sign.
Diastereomers can be defined as a pair of stereo isomers that are not enantiomers. This indicates
that the isomers are not mirror images and they totally differ from each other. Enantiomers
though nonsuperimposable mirror images they have same physical and chemical properties, they
differ only in rotation of plane polarized light. Diastereomers have different physical and
chemical properties.
2. The disaccharides are composed of two monosaccharide units. Maltose, Lactose and Sucrose
are the examples of disaccharides. These are referred by their common names like, Malt sugar,
Milk sugar and Table sugar. Galactose is a hexose molecule. It is one of the components of
disaccharide Lactose or milk sugar. It is found in the milk of mammals. -D - N -

Can a degree 3 polynomial intersect a degree 4 polynomial in exactly .pdf
Can a degree 3 polynomial intersect a degree 4 polynomial in exactly five points? Explain.
Solution
Let, f(x) be degree 3 polynomial
ANd g(x) be degree 4 polynoimal
So points of intersection are given by roots of the polynomial
h(x)=g(x)-f(x)
But, h(x) is degree 4 polynoimal and hence has atmost 4 roots
So there can be atmost 4 points of intersection.

After reading about the history of welfare in the USA, describe in y.pdf
After reading about the history of welfare in the USA, describe in your own words how our
current welfare system came to be. What are your thoughts about Sweden\'s welfare system?
How would creating a similar system in the USA impact the field of human services? Why does
the USA not have a welfare system similar to Sweden?
Solution
The US has the largest and most technologically powerful economy in the world, with a per
capita GDP of $49,800. In this market-oriented economy, private individuals and business firms
make most of the decisions, and the federal and state governments buy needed goods and
services predominantly in the private marketplace. US business firms enjoy greater flexibility
than their counterparts in Western Europe and Japan in decisions to expand capital plant, to lay
off surplus workers, and to develop new products. At the same time, they face higher barriers to
enter their rivals\' home markets than foreign firms face entering US markets. US firms are at or
near the forefront in technological advances, especially in computers and in medical, aerospace,
and military equipment; their advantage has narrowed since the end of World War II. The onrush
of technology largely explains the gradual development of a \"two-tier labor market\" in which
those at the bottom lack the education and the professional/technical skills of those at the top
and, more and more, fail to get comparable pay raises, health insurance coverage, and other
benefits. Since 1975, practically all the gains in household income have gone to the top 20% of
households. Since 1996, dividends and capital gains have grown faster than wages or any other
category of after-tax income. Imported oil accounts for nearly 55% of US consumption. Crude
oil prices doubled between 2001 and 2006, the year home prices peaked; higher gasoline prices
ate into consumers\' budgets and many individuals fell behind in their mortgage payments. Oil
prices climbed another 50% between 2006 and 2008, and bank foreclosures more than doubled
in the same period. Besides dampening the housing market, soaring oil prices caused a drop in
the value of the dollar and a deterioration in the US merchandise trade deficit, which peaked at
$840 billion in 2008. The sub-prime mortgage crisis, falling home prices, investment bank
failures, tight credit, and the global economic downturn pushed the United States into a recession
by mid-2008. GDP contracted until the third quarter of 2009, making this the deepest and longest
downturn since the Great Depression. To help stabilize financial markets, in October 2008 the
US Congress established a $700 billion Troubled Asset Relief Program (TARP). The
government used some of these funds to purchase equity in US banks and industrial
corporations, much of which had been returned to the government by early 2011. In January
2009 the US Congress passed and President Barack OBAMA signed a bill providing an
additional $787 billion fiscal stimulus to be used over 10 ye.

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

You are examining a copolymer for its potential as a material for .pdf
- 1. You are examining a copolymer for it's potential as a material for a vascular graft. you are trying to determine whether you want a high or low degree of crystallinity in the material. what type of structures for copolymers have a higher probability for crystallization? Solution Answer: Copolymers are formed when two or more different types of monoers polymerize in a process called copolymerization. A block polymer is formed by the copolymerization of different copolymerized monomers. The first component is styrene followed by methyl methacrylate which forms at the end of polystyrene chain. Alternating polymers have regular repeating units of two different monomeric units. Block and alternating polymers can form long range repeated, ordered structures and thus have a higher affinity for crystallization.
