The Course Of Human Evolution Essay

The Course of Human Evolution Essay
Human life histories are understood to consist of different levels of factors that contribute to the
variation and evolution of human health, and this can be analyzed by categorizing the various
lifetime events on a fast–slow continuum (Promislow & Harvey, 1990 as cited in Kaplan, Lancaster,
& Robson, 2003). Mammals, for example, are located on the fast end of the continuum and are
known to reproduce early, have a shorter period of pregnancy, grow into smaller body sizes, and
produce a great amount of offspring that are vulnerable to death. On the other hand, species
scattered on the other end of the continuum tend to have characteristic that are opposite to those of
mammals (Kaplan et al., 2003). These changing momentums are generally ... Show more content on

How has human health history progressed? In order to understand the momentum of human
evolution, we have to look at that evolution from several different perspectives. Kaplan et al. (2003)
proposed an "embodied capital theory" which suggests that there has been an integration of life
history and investment in economics that forms the building blocks of somatic appearance. This
theory purports to explain the development and maintenance of human health. The "embodied
capital" refers to the physical organization of the human body and the functions of the various
internal organs (Kaplan et al., 2003). This "capital" provides solutions to problems that may not
have been addressed or completely understood. For example, the human brain is one type of
embodied capital that supports the ability to learn new information even after adulthood has been
reached, notwithstanding the fact that in adulthood the brain has reached its peak mass (Kaplan et
al., 2003). Nonetheless, due to the tendency of devaluation in such embodied capital, there seems to
be some costs and benefits throughout one's lifetime. For example, there may be a reduction in the
brain system and cognitive perception early in life that results in incompetence of human infants
(Kaplan et al., 2003). On the other hand, in a circumstance where there is little information to
absorb, the human

The Pros And Cons Of Life
Everyday technology and scientific discoveries are being made in the field of aging. In a society
obsessed with staying young, one must ask themselves: When is life too long? In these next two
articles, we examine and analyze the benefits, side effects and the complications that come with
living longer lives than we are accustomed too. These articles are "Who wants to live forever? Three
arguments against extending the human lifespan." By Martien A. M. Pijnenburg and Carlo Leget
and "Science Can Help Us Live Longer, But How Long Is Too Long?" by Randy Rieland. The first
article discusses three arguments against the idea of humans living longer lives. While the second
article considers the pros and cons of living a longer life and why most people refuse comply. Even
though, both articles present great arguments and a thorough understanding of the subject they
discuss, Pinenburg's extensive research, experience and credentials make his article the favorable
choice to write a research paper on. Both articles present similar arguments on the same subject,
nevertheless, they demonstrate contrasting styles of writing. The first article "Science Can Help Us
Live Longer, But How Long Is Too Long?" by Randy Rieland has a more simplistic writing style
and takes a more laid–back approach. Rielands article appeals to a wider audience. He includes
photos and writes from the perspective of the average middle–class citizen. The first examples he
mentions is, "While 80 percent of those

shorter life spans, it gives them health problems, and when forced to live in captivity they become
killing machines. Orcas should not be kept in captivity because they have shorter life spans.Orcas in
the wild have an average life expectancy of 30 to 50 years–their estimated maximum lifespan is 60

Years ago I read a book that was set in a Sci–Fi–esque WWII environment where vampires and
other mystical creatures came out of bastardized science experiments. In this story, you follow a
troop of british soldiers as they fight the nazi equivalent of the story. About half way through the
story they "liberate" the lab that was doing these experiments to find in a large steel room sealed by
blast doors a "vampire" they have a brief conversation with the creature before he decides to tell
them his story. His story is one of loss and defeat how all the people that he knew or were important
to him had already died and that he'd lived for 6 centuries and no longer wanted to "endure the pain
of living in this alien world" then he started to beg the soldiers to kill him but despite their best

The Penang Second Brigde in Malaysia
The Penang Second Bridge is one of the longest in Malaysia and also in the South East Asia region.
It is also known as the Sultan Abdul Halim Muadzam Shah Bridge which is named after the Sultan
of Kedah. The bridge connects from Batu Kawan on the mainland to Batu Maung on the Penang
Island. It has an overall length of 24km and a length over water (displacement) of 16.9km. It is
much longer when compared to the Penang First Bridge which only has an overall length of 13.5km.
The building of this bridge has cost the government for RM4.5billion.
The planning of building the second bridge to link the mainland to the island has been brought up
back in the year of 1995 by the 4th Prime Minister which is Tun Dr. Mahathir Mohammad and also
the 3rd Chief Minister of Penang, Tan Sri Dr. Koh Tsu Koon. Later, Malaysian government unveiled
the plan to construct the bridge in August 2006. The project is implemented in the 9th Malaysian
Plan. It is the largest civil construction work carried out in Malaysia in the past 2 decades.
The construction of the bridge officially started in November 2008 after all the planning and
procedure done. The bridge is currently projected completed on February 2014. The bridge is built
under the cooperation between China and Malaysia. The project itself was funded by China through
the Export–Import Bank of China as Malaysia signed RM2.7bilion loan agreement in July 2007.
Besides that, Malaysia also cooperated with the contractor from China that is China

Early-Life Disadvantages
The literature on environmental factors and their effect on health and life expectancy is extensive.
Studies of mortality have found that childhood health and socioeconomic context are important
predictors, often regardless of adult experiences (Motez and Hayward 2014). One study examines
whether early–life disadvantages both shorten lives and increase the number of years lived with
functional impairment (Motez and Hayward 2014). These early life disadvantages could be health,
socio–economic, or environmental related. Within levels of educational accomplishment, adults
from underprivileged childhoods lived fewer years, and spent a greater portion of life impaired
compared with adults from advantaged childhoods (Motez and Hayward 2014). Higher levels of
education did not improve the health consequences of disadvantaged childhoods. However, because
education had a better impact on health than childhood socioeconomic setting, adults from
disadvantaged childhoods who achieved high education levels often had a length of life that was
similar to those from privileged childhoods who achieved low education levels. (Motez and
Hayward 2014). Recent research has identified a trend that supports the research of Motez and
Hayward. Historically, there has been a penalty associated with urban places, also known as the
rural mortality penalty (James 2014). However, in recent decades, a reversal has occurred (James
2014). Beginning in the mid–1980s, rural and urban mortality rates

Reasons Women Live Longer Than Men
Reasons why women live longer then men
It is an accepted fact of life that men enjoy certain physical advantages over women. Men are
stronger, taller, faster and less likely to be overweight, but they have then tendency to die before
their female counterparts. Their date rate is higher than women in many different societies. Women,
as a group, live longer than men. In all developed countries and most undeveloped ones, women
outlive men, sometimes by a margin of as much as 10 years. In the U.S., life expectancy at birth is
about 79 years for women and about 72 years for men. The gender discrepancy is most pronounced
in the very old: among centenarians worldwide, women outnumber men nine to one. The gender gap
has widened in this century as ... Show more content on Helpwriting.net ...
Chromosomal differences between men and women may also affect their mortality rates due to
diseases. Chromosomes carry genetic mutations that cause a number of life–threatening diseases,
including muscular dystrophy and hemophilia. Because women have two X chromosomes, a female
with an abnormal gene on one of her X chromosomes can use the normal gene on the other and
thereby avoid the expression of disease even though she is still a carrier of the defect. Men, in
contrast, have one X chromosome and one Y chromosome, and so they cannot rely on an alternative
chromosome if a gene on one of the sex chromosomes is defective. If a man has a defect in this
gene, his body's ability to repair the mutations that arise during cell division could be severely
compromised. The accumulation of such mutations is thought to contribute to aging and disease.
The second X chromosome as a longevity factor in and of itself. Although one of the two Xs is
randomly inactivated early in life, the second X seems to become more active with increasing age. It
may be that genes on the second X activates and compensate for genes on the first X that have been
lost or damaged with age.
A third reason for the mortality rate be higher for males is the fact that men are more likely to
engage in risky life–threatening behavior thus raising the mortality rate among them. While this is a
more social reasoning it can be explained using biological terms. The male specie

Gender differences also had to be dealt with accordingly also. Reason being, females average life
expectancy is roughly 6–10 more years (Data ranges over different countries) than males. Beginning
the experiment, one of the subject's parents was asked to sit down with the subject's teacher at that
time and together rate the subjects personality with a given 25–trait dimension. Now that all of the
participant's dispositions were categorized accordingly, the next step was to create equations that
would evaluate a person's life expectancy at different points in their lives. Although several analyses
were made during this experiment, the focal one was the hazard regression analysis. This analysis
calculated mortality rate at all different ages by closely relating it to the personality dimension of the
participant (Friedman, Tucker, Tomlinson–Keasey, Schwartz & Wingard, 1993). After running
through all the data and placing it in the appropriate equations, astounding results were revealed. As
expected woman had a greater life expectancy then men, along with showing a mortality hazard rate
that was two–thirds the rate of men. Out of the six different personalities that a subject could have
been, two tested positive to being strong predictors on influencing longevity, whether it be longer or
shorter life expectancy. These dispositions were Conscientiousness and Cheerfulness.
Conscientiousness predicted longer longevity and cheerfulness predicted a

According to the Functionalist Theory, there are a number of gender inequalities that women face,
which are a product of traditional divisions in society. More specifically, for centuries men have
been known to attend to objectively rewarded tasks such as wage earning, while women attended to
more subjectively rewarded tasks such as child rearing. Although both types of labor are vital for
society 's survival, the tasks performed by men have always been more highly rewarded. From
childhood, men and women are taught these traditional roles and have conformed to them.
Functionalist Theorists explain that gender roles and their inequalities have changed somewhat in
industrialized societies, however, the traditional arrangement remains in force in most societies. It is
these inequalities that have led to population problems between men and women such as the rape of
women and violence against women. In fact, women between the ages of 15 to 44 suffer more
deaths from domestic violence than cancer, malaria, and road traffic. Also, there are some main
differences in the types of health issues that men and women face that shows then gender disparities
in developed countries. For example, women have the added issues of maternal mortality rates that
indicate that more than one woman dies every minute of every day due to preventable complications
of pregnancy, childbirth or unsafe abortion. Other hand, men 's more risky

Every Running Business Needs Working Capital
Every running business needs working capital. Even a business which is fully equipped with all
types of fixed assets required is bound to collapse without adequate supply of raw materials for
processing; cash to pay for wages, power and other costs; creating a stock of finished goods to feed
the market demand regularly; and, the ability to grant credit to its customers. All these require
working capital. Working capital is thus like the lifeblood of a business. The business will not be
able to carry on day–to–day activities without the availability of adequate working capital.
Subsequently, with the usage of fixed assets resulting in value additions, the raw materials get
converted into work in process and then into finished goods. When sold on credit, the finished goods
assume the form of debtors who give the business cash on due date. Thus 'cash' assumes its original
form again at the end of one such working capital cycle but in the course it passes through various
other forms of current assets too. This is how various components of current assets keep on
changing their forms due to value addition. While managing the working capital, two characteristics
of current assets should be kept in mind in which is a short life span, and swift transformation into
other form of current asset. Each constituent of current asset has comparatively very short life span.
Investment remains in a particular form of current asset for a short period. The life span of current
assets depends

Robinson, a then corporal in the RCMP, was off–duty at a party where he consumed multiple beers.
After the party, Robinson decided to drive home, despite his intoxication, and on his journey, he hit

and when he returned home he consumed two more shots of vodka, in order to skew the
breathalyzer results. After an investigation, Robinson was charged with obstruction of justice for
consuming the shots. He was never charged with anything relating to the death of Hutchinson, even
though, according to the Criminal Code, Robinson committed Impaired Driving Causing Death;
which is described as "[operating] a motor vehicle...while the person's ability to operate the
vehicle...is impaired by alcohol or a drug" (Criminal Code, s 253). When one causes death whilst
impaired there is a maximum sentence of life in prison. Again, this is a maximum, and it's
unreasonable to expect the maximum every time a crime is committed. However, in a similar case

The great divide in cognitive thinking is between is between theories which assist moral rights and
wrongs in terms of consequences of doing certain actions and some which do not consider actions.
Those which consider actions are consequentialist theories and those which do not are non–

behavioral theory that aims to attain a set end or a consequence. This theory does not consider any
right or wrong virtue, deed or moral its only aim is to achieve its goal. And all the things coming in
the way of achieving that goal or purpose or end are considered as tool. The two most influential

The action however apparently is not intrinsic in nature but the consequence gives the maximum
advantage to the poor people who are deprived of their basic needs. The needy do creates the
maximum contentment for the maximum number of people. In Robin Hood's place and time,

people suffering from it. Rule Utilitarianism: tells one to obey the rules that bring the maximum
happiness to the greatest number of people. Rule utilitarianism maintains a behavioral code or rule
which is good if the consequences of adopting the rules favorable to the greatest number of people.
For Example: In court a person who gets his right of justice because of jurisdiction following their
set and assigned rules and code in law book this will eventually leads to the advantage of maximum
number of people as maximum number of people are satisfied because they are being provided with
justice because of the court following the rules of law. Another example in distribution of food to the
workers during lunch hour; they are supposed to make a queue in order to get the food they desire,
assembled in the dishes in a row. If workers break the rule of being in a queue there will be a chaos
and not everyone will be able to take the food as the lunch break is of limited time span. The act of
following the queue rule will help all workers to get their desired food within the limited time

them. Having a good, system of support not only enables peoples to help each other, but also
enables them to express their feelings, including happiness and sadness's and other aspect of
confidence. For example, when we are feeling bad everything in the world seems differently to us,
because our bad mood can affect our thinking process, but talking to someone you trust or a good

Quality Of Life Or Longevity
There are lots of arguments about what is important for living– Quality of life or longevity? Quality
of life is more important to me than the long duration of life or longevity. Because living long in
poor conditions is worthless, it does not means living it just surviving. Before I explain my position
in this topic I would like to give a general idea about what is 'Quality of life' and what is 'Longevity'.
Quality of life is subjective and also multidimensional. It indicates the general well–being of
peoples and their societies including their physical health, family, education, religious beliefs,
finance and the environment also. It is quite different from the 'standard of living' which just focused
on income. Longevity which also can be ... Show more content on Helpwriting.net ...

another. Longevity with reduced quality of life is meaningless to me. I would prefer quality of life
rather than longevity. For example, suppose I am going to a long drive on a highway, at the same
time I crushed my car with another car. Few hours later I found myself in an intensive care unit after
the horrible accident. After one month I found myself in a wheelchair, and can't communicate, can't
do anything, having serious pain in my body, needs help for moving anywhere. Does this type of
lives meaningful to me? Is this my quality of life? My answer is absolutely 'no'. It indicates my
quantity of life not quality of life.

Seaworld: The Importance Of Whales In The Sea World
The multibillion–dollar company that is SeaWorld, regularly has Orca shows in an Olympic size
pool, 9 times that. Orcas in the wild need space to move around, and shouldn't be kept in small
spaces for health problems. Many health issues this causes are collapse fins, and dying at a
premature age. In the wild, we hardly see Orcas with collapsed fins, only 1% of Orca population
have collapse fins. Because of the lack of space man fins get in the way of play. There aren't bones
in their fins, so it can easily bend. Bending in the fin can be passed down in offspring. Even though
whale shows bring in a lot of tourism, which helps the economy grow, it doesn't justify the
conditions these whales have to endure in captivity. Orcas in the wild have

The Importance Of Sustainable Water Practices For The...
Sustainability is the "development that meets the needs of the present without compromising the
ability of future generations to meet their own needs" (World Commission on Environment and
Development, 1987). Water is a principal compound for human life across the globe. Although there
is of 1.4×109 km3 of Water on Earth, only 0.37% of that is drinkable (Murphy, 2004). The inability
to access this clean water then causes water borne diseases, particularly in poorer nations, such as
Cambodia where only 14% of the population has access to drinkable water (Brinkley, 2011). This is
then the reasoning behind the 3.4million deaths annually by water borne diseases within the
developing world (World Health organisation, 2001). As 70L of water/day ... Show more content on

2 BIO SAND FILTERS
2.1 Design
There are seven components to a biosand filter design. These are; the lid, diffuser, sand layer, outlet
tube, filter body, gravel layer and the separated gravel layer (Cawst, 2009). All of these components
all contribute to the purification of water. The purpose of the lid is to protect the water from any
external contamination. The diffuser is a plastic sheet with holes drilled into it and protects the
biolayer while the water is being poured in (CDC, 2014). This is achieved through slowing down the
rate of the water. The third component is the sand layer and this removes any suspended solids
within the water. This is able to occur through the use of mechanical trapping and the solids being
trapped in between the grains of sand (Cawst, 2009). The separating gravel layer is purely placed in
the filter to support the sand layer on top while the drainage gravel layer's purpose is to support the
flow of water into the outlet tube. The use of bigger rocks is used for this drainage layer to prevent
smaller rocks accessing this outlet tube (Cawst, 2009). The outlet tube brings the water from the
bottom of the

The Nickel Electrode Batteries Are Vulnerable
The nickel electrode batteries are vulnerable to both reversible and irreversible degradation. The
reversible degradation forms can be rectified by fully discharging the cell and then recharging it.
The irreversible forms of degradation vary depending on the types of electrodes and the application
of the battery. However, the irreversible forms of degradation are majorly linked to the number and
depth of the discharge/recharge cycles and the operation temperatures. The primary causes of
irreversible degradation include the decomposition of the organic material into the electrolyte,
corrosion of the nickel electrode, dendrite formation on the surface of the negative electrolyte,
electrode poisoning, and the failure of the gas barrier. Additionally, the nickel electrode batteries are
vulnerable to "thermal runaway," which can be described as a vicious cycle caused by heating and
augmented discharge and voltage. The batteries are also susceptible to gassing, which can lead to the
buildup of pressure in the cell that may lead to permanent battery damage. The batteries are also
engrossed by a number of safety and environmental concerns because they are manufactured using
an extremely toxic metal cadmium. However, the concerns have been lessened through regulation,
keen monitoring during manufacturing, and elevated recycling efficiencies. Currently, there are
three major categories of the nickel–cadmium and nickel–iron batteries; namely, vented sintered
plate, pocket plate,

What Does Dragonfly Function?
Example of an insect with incomplete metamorphosis is Dragonfly Like any insects, the dragonfly
has a 3–component frame: a head, a thorax, and a protracted thin, segmented stomach. The
dragonfly has 2 massive compound eyes that absorb maximum of the head. On the short thorax
there are three pairs of jointed legs and pairs of long, sensitive, membranous wings. The dragonfly
breathes via spiracles (tiny holes inside the abdomen). Existence cycle: A dragonfly undergoes
incomplete metamorphosis. The larva hatches from an egg that is laid in water, in vegetation near
water, or maybe underwater. As this aquatic (residing in the water) larva (known as a nymph) grows,
it molts (loses its vintage pores and skin) often. While fully–grown, it emerges

aluminum frames are more durable than wood but the problem with these frames is that they offer
less insulation as compared to other materials. So if you choose aluminum frames, you might need
to add thermal breaks to increase insulation. It's better if you consult with your contractor first. Vinyl
frames offers great insulation among all when you compare replacement windows and it is the best
solution but they incur more cost upfront. But you need to keep in the mind that they recover the
cost in short life span. Low cost replacement windows are also available in the market these days.
Selection of Panes You may go with one, two or three panes in your windows. The number of panes
impacts on insulation. If you want great insulation, you should go for double or triple pane
windows. But they incur more cost as compared to single pane windows. So it is recommended that
first you set your budget and then select replacement windows with appropriate number of panes.
And in the end, I would like to suggest you all that whatever replacement windows you install do

Essay On Long Term Care Insurance
The popularity of Long–Term Care insurance (LTC) insurance policies has been growing since its
inception in the 1980s. Unlike traditional health insurance, Long–Term Care insurance(LTC), covers
care generally not covered by health insurance, Medicare, or Medicaid, including personal and
custodial care in a variety of settings such as home care, a community organization, or other facility.
As baby boomers hit retirement age the question of long–term care Insurance has become very
prominent the retirement and financial planning industry. The idea of long–term insurance is to help
seniors avoid losing their next egg to health care cost beyond what they may be covered on
Medicare and Medicaid.
According to a New England Journal of Medicine reports in May of 2000 almost 51% of people 65
years and older are expected to need long–term care as some point. The Wall Street Journal also
notes that about 55% of seniors 85 and older today have Alzheimer's or some other form of
dementia which is one of the principal reasons for needing long–term care assistance. Achievements

Design A Safety And Longevity Bridges
In designing the bridges, an engineer need to completely understand the problem to be solved. To
design a safety and longevity bridges, they have to consider different types of loads, how and where
they need to apply the load. They also have to undergo several steps that usually need in designing
bridges such as understanding the problems, determining the potential loads of bridges, calculating
the highest possible loads and calculate the amount of material need to counteract the loads.
Retrofit is one of the important features of maintenance. It is can be defined as upgrading or
strengthening the bridge structural quality to enhance the performance of the bridge. Strengthening
and retrofit methods are different from the repairing and it includes a component host. Most bridges
are in need for the retrofit and strengthening every 15 years. There are a lot of strengthening
methods like steel pre–stressed girders, micro piles, pile caps, extended footings, abutment wall,
wall piers and column bent pier. Other than that, there are also concrete deck repair by patching,
epoxy injection, silica fumes and salvaging of existing railing and beam where it is customary to
retain the existing ones. If demolition needs to be conducted, extra care is strictly prohibited so that
the features that required for continuity are not damage.
There are a few ways to retrofit bridge structure to prevent it from collapse. It is because these

Survivorship Gap Gender
(3a) From Figure 1, we can clearly see a distinct separation in the survivorship curves between
males and females of the post–1950 population at around age 51, where females show higher rates
of survivorship than males; however, this obvious sex gap does not occur in a pre–1910 comparison
of gender mortality. Instead, the pre–1910 survivor ship curves for both genders begin to oscillates
near similar survivorship values at age 31, which could be the result of environmental variation
during that time period. Nonetheless, the maximum longevity of women surpasses that of men in
both populations. (3b) Studies have shown the effects of social relations on psychological wellbeing,
where high quality relationships between individuals decrease the

The Golden Gate Bridge Essay
The Golden Gate Bridge
Since the dawn of time, man has had an inherent need to get to the other side. Rivers, canyons, and
impassable trails have always hindered the migration of man, leaving him the choice to continue no
further, or to "build a bridge and get over it." The earliest bridges were made of simple materials
such as stone, or even a fallen log. Regardless of the material, natural bridges allowed man to
explore the "other side." However, man has never been satisfied with what nature gives him. Over
time, man developed the ability to construct his own bridges in order to create a shortcut across an
otherwise impassable obstacle. The first man–made bridges consisted of wooden beams or stone
arches. With each ... Show more content on Helpwriting.net ...
The Golden Gate Bridge broke span records and set new safety standards in the bridge building
community. Although architects and engineers designed a safe structure, various improvements such
as a lighter deck and reinforced steel trusses have been added over the years. The Golden Gate
Bridge, in all its glory, is a true structural wonder for both its size and artistic design.
Although actual construction began in January of 1933, the idea for the Golden Gate Bridge began
back in 1872. At that time, railroad entrepreneur Charles Crocker envisioned bridging the gap across
the entrance to San Francisco Bay from the Pacific Ocean. The idea was deemed unfeasible at the
time and was put to rest until 1916, when James Wilkins, a newspaper editor, began to heavily
promote the idea of building a bridge across the Golden Gate Strait. This time the proposal caught
the attention of various bridge engineers in the area. The initial response was that the bridge would
be difficult to build and cost in excess of 100 million dollars. Joseph Baermann Strauss stepped in
with his proposal that, not only could the bridge be built, but construction would cost less than thirty
million dollars. He even believed that tolls would soon pay for the expenses. On June 28, 1921
Strauss submitted his plan to build the Golden Gate Bridge for twenty seven million dollars. While
the City of San Francisco needed the bridge to accommodate the rapid population boom, it lacked
the funds to

The Tacoma Narrows Bridge, was also known as the Galloping...
The Tacoma Narrows Bridge, was also known as the Galloping Gertie, was one of the most famous
cause study of structure failure in the world. The idea for constructuring of the bridge came up in the

concreted and construction with the cost of over 6,400,000 dallors, the bridge was been build and
became the third longest and the most flexible suspension bridge in the world of its time of 1900s
with a toatl length of 1810m. It was designed as a twin suspension bridge which located between
Tacoma and the Kitsap Peninsula in United States. The Tacoma Narrows Bridge opened for traffic
on July 1, 1940. After being in service for 129 days, ... Show more content on Helpwriting.net ...
Prior of this time, most bridge design were based on trusses, arches, and cantilevers to support
heavy freight trains. Automobiles were obviously much lighter. Suspension bridge design had been
envolving into producing bridges of maximum grace, lightness and flexibility which actually was
more suited for carrying lighter cars and not heavier train. Unfortunately, engineers did not fully
understand the response of the suspension bridge design to these poorly understand forces. The
second reson was due to the excitation of torsional mode. The Tacoma Narrows Bridge was built
with shallow plate girders instead of the deep stiffening trusses of railway bridges, in which trusses
allowed wind to pass through but plate girders, on the other hand, present an obstacle to the wind.
As a result of its design, it was proved that the bridge was too light and unstable. And causing
alloping Gertieaction which were driven by the wind were being experienced by the bridge.
During the morning of 7 November 1940, the wind with around 56.3 km/h (35 miles/h) excited
bridge`s transverse vibration mode to its maximum amplitude of vibration of 0.5 m within three
hours. Then the wind started increasing to 67.6 km/h (42 miles/h). One supporting cable at the mid–
span snapped causing unbalanced loading. The bridge response thus changed to a 0.2 Hz torsional

these trends can be seen in a number of species. It is generally believed, from an ecological
perspective, that populations will display either an exponential of logistic growth rate. If optimal
environments are consistently maintained with no biotic or abiotic limiting factors (excess food,
excess space availability, optimum climactic environment, no predation, etc) then a population will
grow in an exponential direction. Species with high maximal relative growth rates do not occupy
infertile habitats because their physiologies are more sensitive to suboptimal habitats and so their

Each bottle was filled 3/4 full with spring water from the San Marcos River. The water levels in the
bottles were marked for future reference. Ten large Daphnia magna were carefully placed n each
bottle along with a pinch of Spirulina (powdered algae). For the duration of the experiment, only the
supplemented group of Daphnia magna received food weekly, the unsupplemented did not. Spring
water was added periodically to the bottles when the water levels were below the line marked
previously. Each week the numbers of Daphnia were counted utilizing a light source in order to
illuminate the Daphnia and allowed them to be visible. The daphnia were placed in the designated
lab area that maintained at room temperature. The data for a total span of 8 weeks was pooled and

Ultra High Performance Concrete ( Uhpc )
1. Introduction
Ultra high performance concrete (UHPC) represents a major progress step over normal strength
concrete (NSC) and high strength concrete (HSC), through the achievement of very high strength
and very low permeability. Basically, the UHPC is a concrete with compressive strength ranging 120
to 400 MPa, this "ultra" high strength is achieved through different techniques including the use of
improved materials, ultra–fine pozzolans (e.g. silica fume), low water–cement ratio, improved
quality and higher dosage of superplasticizer, use of fibers (metallic or synthetic) to increase the
energy absorption capacity and decrease brittleness, high cementitious materials content, longer
mixing time and heat treatment [1]. UHPC tensile strength varies from 10 to 30 MPa; and the
modulus of elasticity is in the range of 60 – 100 GPa [2].
Using UHPC in the construction of new bridges and the renewal of existing highway bridge network
can minimize maintenance requirement in the construction of new long life bridges resulting in low
life cycle costs [3].
Despite its exceptional material properties, UHPC's initial construction cost is significantly higher
than that of normal strength concrete (NSC), which limited its use in North America and elsewhere.
To address some of the challenges facing bridge owners, the structural efficiency and cost–
effectiveness of using UHPC in composite construction is investigated in this paper. Therefore,
combining NSC with UHPFRC in a composite

The Issue Of Longevity : How Much Difference A Recognized...
The issue of longevity is fraught with vague studies and controversies about how much difference a
recognized number of attitudes and behaviors can make. However, the essence of success is hinged
on a tenant that is skewed much differently than many societies subscribe to. The alliance of
longevity does not rely on individual responsibilities to be successful. Rather, it is heavily dependent
on the concept that individuals are all part of a system, and for enduring gains in health,
communities should shift their tactics away from trying to change individual behavior to optimizing
the surroundings they live in. Dan Buettner performed extensive data analysis and research to
pinpoint hot spots–regions called blue zones to locate the world's longest lived people. He focused
primarily on geographic localities that had not only the highest medium of 100–year–olds, but also
clusters of people who had grown old without conditions like heart disease, obesity, cancer, or
diabetes. Remarkably, each of these sites shared a common denominator: the recipe for longevity is
deeply intertwined with community, lifestyle and spirituality. In Okinawa, Japan, the largest island
in a subtropical archipelago, is home to the world's longest–lived woman, 103–year old, Ushi
Okushima. Okinawans have among the lowest mortality rates in the world from a multitude of
chronic diseases of aging, and as a result, enjoy not only what may be the world 's longest life
expectancy, but the world 's longest

Advantages Of Prestressed Concrete
1. Prestressed concrete is a combination of high strength concrete and steel which can readily be
used in prefabricated structures.
Prestressed concrete is a procedure where the loadbearing strength of concrete is increased
significantly. Basically, it is a concrete in which suitable internal stresses of suitable magnitude and
distribution are introduced so that the stresses caused from the external loads are neutralized to an
anticipated degree. The benefit of prestressed concrete is that it can be used for construction of large
spans (more than 30m) with slender members, even on encountering with heavy loads. As enhanced
materials (controlled concrete and high tension steel) are being used, the modulus of elasticity is
higher and ultimate creep strain is smaller resulting in the reduction of cross section of the structural
components. Due to smaller dimensions, there is reduction in loads causing smaller deflections and
lead to saving cost in the supporting members and foundations.
Further, the pre–stressing technique has eradicated the weakness of concrete in tension obtaining
crack free members of structure wherein the tensile zones are minimized and cracks are limited
under permanent loads increasing the structural durability consequently. To cite an example, in a
prefabricated concrete slab on the steel ... Show more content on Helpwriting.net ...
On comparing to a reinforced concrete component, an element made of high strength concrete will
have minor deflection, slighter camber change, lower pre–stress loss and longer life relatively.
Additionally, it gives heightened shear capacity of columns and stronger beam–column joints. The
other characteristics of high strength concrete are higher compressive strength, better tensile
strength and improved
