Until the 12th and 13th centuries, cross–cultural interactions were unprolonged and less in number
when compared to later centuries. However, the assimilation of much of the Eurasian landmass into
the Mongol empire as well as the later European exploration of the Americas contributed to the
creation of prolonged global connections in which the world's major continents were connected.
Two of the most notable developments include the caravel, which aided European explorers in their
conquest of the Americas, and the stirrup and composite bow, which the Mongols used to conquer
Eurasia and eventually led to the Pax Mongolica. These technological developments had major
effects on both societies.

The Mongolian stirrup and composite bow aided the Central Asian steppe nomads to create the
world's largest land based empire at the time, which resulted from and in many cross–cultural
interactions. When Genghis Khan first started in the creation of his empire, he used his stirrup–
mounted archers in units of 10 squadrons and 1000 men to invade China, where he first learned of
Chinese war technologies like catapults, gunpowder, and the use of Chinese silk as protective
clothing. He then combined all the technologies he obtained with the use of the composite bow and
stirrup. These Mongol technologies helped horsemen to fire highly accurate shots due to the stability
the stirrup provided (Doc. 1). Genghis Khan also used brilliant tactics that allowed him to conquer
large areas quickly. After his rule, the Mongols continued using his tactics. For example, they flung
infected corpses into cities such as the Byzantine city of Kaffa. Using the technologies of the stirrup
and the composite bow allowed Genghis Khan and his successors to conquer and create an immense
empire. This empire eventually covered areas from China to Russia. While destruction, terror, and
intimidation were used to conquer people, Genghis Khan also

1.1 INTRODUCTION Composite materials are defined as the combination of more than two
materials, one of the material is called reinforcement material and another one of the material is
called matrix, the reinforcement materials in the form of fiber particle, ex; – glass fiber for natural
fiber, coconut shell powder matrix material and in the form of resin ex: – phenyl formaldehyde or
epoxy, urea formaldehyde and so on.
Glass fiber reinforced polymers are fiber reinforced polymers, made up of plastic matrix reinforced

For example, on a weight–for–weight basis, graphite/epoxy composites are nearly five times
stronger than steel. The reasons being why they are the most common composites include their
lower cost, higher strength, and simpler manufacturing principles.
Classification of Polymer Composites
 Thermo set polymers: The chains in thermo set polymers are rigidly joined with strong covalent
bonds, they are insoluble and infusible after cure.
 Thermoplastics: are formed at high pressure and temperatures because the bonds are weak in
polyesters, phenolics, and polyamides. Ideal examples of thermoplastics are polyethylene,
polystyrene, polyphenylene sulfide (PPS) and polyether–ether–ketone (PEEK). Thermo plastic
resins are used as molding components. The advantage of thermoplastic is no chemical reaction
involved there is some reason to increase the heat resistance in thermo plastic one is addition of
filler material. Thermoplastic changes it properties during the heating after regain it properties

The Effects Of Hydrogels
Traumatic injury is the leading cause of death in the United States for peopled under age 44, with
hemorrhage responsible for 40% of trauma mortality. Hemorrhage also contributes to the 90% of
military deaths which occur before medical care is reached (Kauvar, Lefering, & Wade, 2006). This
makes it one of the largest contributors to loss of productive years of life. A reduction in time before
traumatic injuries involving hemorrhage receive treatment would save lives and increase the
productivity of our communities. Typical standard of care for hemorrhage is to apply pressure with

Hydrogels from naturally derived marine biopolymers have been widely studied and utilized in a
large number and range of commercial applications, garnering interest particularly in the
pharmaceutical and medical field (Skaugrud, Hagen, Borgersen, & Dornish, 2013). This is due to
their biocompatibility, biodegradability, and low toxicity byproducts. Marine biopolymers
specifically are desirable due to their high bioavailability. Thus, naturally derived marine
biopolymer hydrogels provide a promising platform for hemostatic devices. Chitosan, derived from
chitin, is the most abundant natural polymer in the world besides cellulose, making it relatively
inexpensive (Esam & Yahaya, 2010). Chitosan has been of interest due to its many advantages as a
biopolymer such as its biodegradability, non–toxicity, bio–compatibility, antibacterial properties,
amenability with simple chemical modifications, and ease of processing and handling, dissolving in
mild acidic solutions (Zhu, Jiang, & Xiao, 2010). Further, chitosan's positively charged amine
groups allow it to interact with the negatively charged surfaces of cells. As a result, chitosan is able
to adhere to tissue at wound sites through electrostatic interactions (Cuy, 2004). Alginate is another
such biopolymer, extracted from brown algae (George & Abraham, 2006). Alginate has a high
affinity for cations and therefore readily forms a gel through cross–linking (Skaugrud, Hagen,

These stakeholders influence the roles that school counselors fulfill. By collaboration, school
counselors develop a sense of unity among students, staff, parents and community members. School
counselors consult with teams to problem solve in order to respond to concerns that may be present
in the school, such as equity and cultural diversity issues. In addition to being a counselor, school
counselors are coordinators. They coordinate resources for students, families and staff in order to
enhance student achievement. Lastly, school counselors assess and interpret student needs in order
to identify barriers of learning, recognize differences in culture and develop goals for the school's
comprehensive counseling and guidance program. They also use data to implement systemic
change. Systemic change occurs when policies and procedures are examined and changed in light of
new data (Bowers & Hatch, 2002). This change occurs as a result of the involvement of all critical
players in the school system. School counselors and counseling programs in general have
historically faced problem of role ambiguity. Theoretically speaking, school counselors are hired to
offer guidance and counseling services to students. Unfortunately, clarity of counselors' functions
within the school setting has been steamed up with multifarious responsibilities and roles that school
counselors are expected to perform. The researcher was once a guidance counselor, and

The folkloric festival in Casamance is a timely occurrence that gives insight into the regional
cultural qualities of a people in transition. In seeking to penetrate into this subject one has an
opportunity to: 1) better understand the subject of Identity from a universal perspective 2) notice the
'spectra' of correspondence qualities that allow for 'genesis associations' as 'experienced from
responses from actual events in progress– as a 'point of focus' to speculate on the larger question of
African aesthetics and value systems 3) look at the subject of form and interaction dynamics (and
what value a given formal state might have as for 'inquiring into a unified African vibrational and
mental disposition– that could also assist the effort to better understand the subject of Africa from a
continental and universal perspective) and finally 4) to better understand the special role of music,
and what I call 'vibrational dynamics', in composite African culture and what this subject could
mean to trans–African 'vibrational–radiance' as we approach the new millennium. In the first
category, the challenge of identity for this paper will involve an attempt to isolate the kind of 'event–

Advantages And Disadvantages Of Polymer Nannocomposites
Polymer composites are the blend of polymers and filler materials. Disadvantages of polymers such
as low mechanical and electronic properties can be improved through reinforcing with much
stronger and highly conducting filler materials. Thus, fabricating polymer composites is of mutual
benefit to both polymers and fillers. Furthermore, advanced–desired applications can be tailor–
made. Also, compared to polymer micro/nanocomposites, polymer nanocomposites show much
more improved properties such as extremely smooth finishing, excellent mechanical and electrical
properties at lower loadings as low as 0.025 volume % (Schandler, Brinson & Sawyer 2007). In the
current chapter, both polymer microcomposites and polymer nanocomposites are briefly discussed.

Each category has its own advantages and disadvantages. For example, thermoplastics soften on
heating and eventually melt like metals (Dyson 1990). The present chapter concentrates on two
popular thermoplastics such as poly(vinyl alcohol) (PVA) and poly(methyl methacrylate) (PMMA)
for fabricating conducting polymer nanocomposites (Kennedy & Taylor 1991). Thermosetting
polymers are very common types of polymers, widely used for making conducting polymer
composites. Almost 5th of polymers are used are thermosetting polymers as they find applications as
they are used as composites, adhesives, and coatings (Allin 2004) These polymers are also called as
thermosets which do not melt upon heating, cannot regain its shape once it is moulded. Among the
three plastics, polyester is easy to use and very cheap. Vinyl ester shows the best chemical resistance
compared to other, and high mechanical properties than polyester. Epoxy is expensive than vinyl
esters. The present report discusses the three types of thermosets such as epoxy, vinyl ester, and

The Structure Of Polypyrrole
The structure of polypyrrole consists of long conjugated polymer backbone as shown in Fig. 1.2b.
The polymer has resonance structures that resemble aromatic or quinoid forms. In this neutral state
the polymer is not conducting and it conducts only when it is oxidised. Polypyrrole is an insulator
but its oxidized derivatives are good conductors. The Conductivity ranges from 2 to 100 S/cm. The
charge associated with the oxidised state is typically delocalised over several units and can form a
radical cation (polaron) or a dication (bipolaron).
Polypyrrole is poorly crystalline, with crystalline regions randomly oriented and the polymer chains
lying with the pyrrole rings coplanar to the surface . Actually polypyrrole obtained so far ... Show

When the polymer is doped partially, islands of conducting material are developed, which are
oxidized sites on the polymer chain. A small percentage of the sites form a network, yielding a small
, finite DC conductivity. Hopping of charge carriers between favourable sites accounts for AC
conductivity. Thus the conductivity is a combination of frequency dependent AC conductivity and
DC conductivity. At higher level of doping, an increase in the network density through the polymer
chain results in elimination of number of isolated sites which give rise to AC conductivity. So at the
limit of very high doping the number of isolated sites is less and the DC conductivity dominates the
total conductivity.

Advantages And Disadvantages Of Scaffolds
As previously defined, a composite material consists of two or more materials where polymers are
used as matrix materials usually. These materials behave together to produce the best properties of
the scaffold, duplicating the same composite features of bone. In particular, polymer– based
composite scaffolds may mimic the structure of natural bone which is mainly made of HA and
collagen. Showing better osteoconductivity, HA can be considered the inorganic reinforcing phase
of the composite scaffold, while polymers such as PCL, PLLA, PGA, PLGA function as the organic
matrix. Bioactive phases creating reinforcement in the polymer–based composite can also change
the degradation behavior. Composite scaffolds made of polymer reinforced with HA seem to be
promising substrates for bone tissue engineering because of their outstanding mechanical properties
and osteoconductivity.

The effective synergic role of –TCP bioactive particles and PLA fibers on the morphology and
mechanical behavior of the final composite scaffold was assessed, as well as the interaction between
the ceramic phase and the highly organized fiber–reinforced polymeric structure (60).
The integration of biodegradable PLA fibers into the PCL matrix allows a mechanical response that
is ideal to maintain the spaces required for cellular in–growth and matrix production. The addition
of bioactive –TCP particles, through a hardening reaction, generates needle–like crystals of
calcium–deficient hydroxyapatite similar to natural bone apatite, which interact with the fiber–
reinforced polymer. This interaction strongly enhances the mechanical response in compression by
up to an order of magnitude

The Best Mental Approaches A Child Should Take

and how they link to the year two national curriculum.
The addition is the first operation children learn from a young age and mastering it, is the first step
toward the long–lasting appreciation of maths. Children from Early Years Foundation Stage (EYFS)
do not need to memorise complex additions in order to become confident with basic addition.
instead, teachers support children to practice counting; counting on, doubling, learning place value
visually rather than mentally and encourage them to do it in different ways. They also use ... Show
However, with subtraction calculations, this is not possible. Hence they are expected to 'use inverse
relationship between addition and subtraction to check calculations and solve missing number
problems.' (NC, 2013).
One of the approaches, which is highly recommended for children to practise, is to do addition
calculations mentally (working out calculations in their head) using various strategies, which is the
focus of this essay. Tony Cotton (2013, p.109) states that developing mental approaches is more
efficient to work out solutions to problems and helps children to become fluent in mental
calculation. However, doing mental calculations, such as addition, can be challenging and confusing
for some children. Therefore, introducing appropriate strategies (for example counting on,
partitioning, bridging through 10) and using them to draw images or mark–making will encourage
children to 'see' calculations in their heads and will allow them to use the strategy which is the most
suited for them (Cotton, 2013, p. 110).
Ian Thomson also suggests (I part 1 addition) that visual representation plays an important role in
developing mental addition. for example, number lines help children to recognise place value and
with prior knowledge of ordinal sense of numbers, it helps them to move from counting in ones to
counting in larger steps, such as 2, 5, 10, 100 and so

force of gravity by using either static lift or by using the dynamic lift of an airfoil. A composite
material is a material made from two or more constituent materials with differing physical or
chemical properties that when joined together, produce a material with characteristics different from
the individual material. The individual component remains separate and unique from the finished
structure. There are a few types of currently available composite materials, and they include carbon
fibre, fiber glass and fibre–reinforced matrix systems. Almost all new aircraft these days include
some composite material into their designs. The most common composite material that is used in
aircraft is fiberglass. Other composite materials used includes Kevlar, which is now replacing glass
fibers. Composite materials had been used commonly since ... Show more content on

Although aeroplanes go through very stringent checks before flying, more time is needed to check
when it is made with the composite material. As composite materials do not break easily, it is hard to
differentiate if the interior structure has been damaged at all. Hence, it requires extensive inspection
techniques for detection. In contrast, for traditional materials like aluminium, due to its nature, it
bends and dents easily. [6] Therefore it is quite easy to find out if there is any structural damage.
Based on experience, an aircraft would be grounded for a few days to repair on the composite
material while only a few hours would be needed for a traditional metallic part. Moreover, repairs
can be much more expensive when a composite surface is damaged. Also, composite repairs are
more prone to human error than metal repairs since the quality of composite repair is highly
dependent on the process

As long as the fish continue to be exposed to mercury, mercury will continually build up in fish's
bodies. Fish that eat other fish grow even more highly tainted. Therefore, the fish most desirable for
many additional bigger fishes become the most affected, and larger sized fish will be the most
contaminated fish. Bacteria and chemical reactions in lakes and wetlands change the mercury into a
much more toxic form known as methyl mercury. Fish become contaminated with methyl mercury
by eating food, which has absorbed methyl mercury. The environment is at a serious risk because of
the levels of mercury in our water supply. Mercury will contaminate the fish and other wild life

missing weight(s) and select the option that keeps the scale balanced (Figure Weights). For instance,
one side of the scale may have one blue circle. The student would then need to select one blue circle
to keep the scale balanced. The task increases in complexity when the student needs to apply the
concepts of addition and/or multiplication to identify the correct response. She performed within the

safer way to improve general health and living. In India, despite of low level of public awareness
compared to western markets, functional foods and ingredients are finding huge growth as
consumers switch on to the promise of healthier foods, beverages and supplements.
On the contrary, due to urbanization the increased demand for ready to eat products at reasonable
costs also increased, particularly the bakery products. But in recent times functional foods are
rapidly increasing in popularity in sectors such as dairy products or confectionery, in bakery it is still
relatively underdeveloped. Bread is one such important staple food and the most widely consumed
bakery product all over the world. In bread making, the use of white flour (refined) has been
increased with an aim of improving the aesthetic value of white bread, which in–turn led to drastic
reduction in the nutritional density and fiber content when compared to bread made from whole
grain cereals. In recent years, cereals and its ingredients such as beta–glucan, arabinoxylan, resistant
starch, oligosaccharides etc are accepted as functional foods and nutraceuticals. Cereals, in
particular oat and barley, offer another alternative for the production of functional foods. By

PROCESS: There are many different processes and techniques used to manufacture CMC. Some
common processes are as follow:– COLD PRESSING AND SINTERING The method of cold press
sintering is similar in making monolithic ceramics. The process is done by adding the ceramic
matrix powder with water to create slurry. An organic binder is added to the slurry to hold the
compound together. The adhesive is burnt off during the sintering process. The composite whiskers
are place into the mix where the compound is pressed under high pressure. Sintering is a process of
heating the material below its melting point where the compound is held in place by self–adhesion.
In sintering the matrix is subject to shrinkage that could result in cracking. Altering the sintering
temperature and ensuring compatibility between thermal expansion of matrix and composite
materials can avoid cracking. [6] LIQUID SILICON INFILTRATION (LSI) LSI is a fast, low cost

FRP composites having superior material properties when compared with metals, improved
corrosion resistance, fatigue resistance, less weight to strength ratio and high fracture toughness.
Hence GFRP composites frequently used in several applications like sports goods, racing car bodies
and aerospace components [1]. Often composite products manufactured by near–net shapes. The
components made by secondary machining processes are involving to get good dimensional
accuracy and geometrical shapes done by turning, drilling and milling operations in a specified
manner [2]. The author has presented in

What Is The Stress Strain Curves Of The Pure SR And SR...
The stress–strain curves of the pure SR and SR composites are presented in Figure 3(a), indicating
that the stresses at 100% strain and 300% strain increase with increasing content of BT particles.
The main reason for the increased stress at definite elongation is the reinforcing effect of the
inorganic particles [38]. In addition, the elongation at break of the SR composites decreased after
adding BT particles, attributed to the BT particles acting as physical links, thus limiting the
flexibility of macromolecular silicone. Because of increasing interfacial areas between the BT
particles and SR matrix, the number of physical links increased significantly in the system,
decreasing the elongation at break of the SR composites with ... Show more content on

Two factors can be used to explain this phenomenon. The first one is the BT particles interact
strongly with the macromolecular SR, thus restricting the mobility of the molecular chains. The
second one is the polymer chain entanglement limits the movement of polymer chains [38]. The
interface polarization will increase the dielectric constant as well as the dielectric loss of the
composites. As shown in Figure 4(b), the dielectric loss tangent of the BT/SR composites is larger
than that of the pure SR at low frequency. In addition, the dielectric loss displays a sharp decrease at
a low frequency (lower than 1 kHz), caused by the DC leakage current. However, the electrode
polarization can be excluded as there is no simultaneous decrease in the dielectric constant and
dielectric loss with increasing frequency [42]. However, because of the weak polarization of the
silicone matrix, the dielectric loss tangent of all the samples is lower than 0.015. The low dielectric
loss means just a little energy dissipation during actuation, a big advantage for dielectric elastomer.
The electromechanical performance of the SR composites was tested using circular actuators.
Considering the safety and utility, the loaded electric field on the samples was 50 kV/mm. The
actuated strains of the BT/SR composites are shown in Figure 5(a). With increasing electric field,
the actuated strain of the samples increases significantly, because it is proportional to the square

Eliminate Tooth Decay
Eliminate Tooth Decay With Tooth–Colored Fillings In Fairfield, Ohio
Cavities are a fact of life that almost everyone has to deal with. It's estimated that about 91 percent
or more of Americans between the ages of 20 and 64 have had cavities. That's a huge percentage of
the country, and the scariest part for me is that many of those people do not have access to the latest
filling materials and restorative treatment method.
At our Fairfield dental office, that's never a risk. Dr. Dine has spent decades treating patients with
state–of–the–art restorative procedures. One of his biggest priorities as a family dentist is to help
patients stay cavity–free and to restore damaged teeth with natural–looking materials!

Even in technical arenas, this variation in terminology is common. A chemist might use the terms
"valance" and "oxidation state" to identify the same concept. Object–Oriented Terms and Concepts
Objects Objects are the physical and conceptual things we find in the universe around us. Hardware,
software, documents, human beings, and even concepts are all examples of objects. For purposes of
modeling his or her company, a chief executive officer could view employees, buildings, divisions,
documents, and benefits packages as objects. An automotive engineer would see tires, doors,
engines, top speed, and the current fuel level as objects. Atoms, molecules, volumes, and
temperatures would all be objects a chemist might consider in creating an object–oriented
simulation of a chemical reaction. Finally, a software engineer would consider stacks, queues,
windows, and check boxes as objects. Objects are thought of as having state. The state of an object
is the condition of the object, or a set of circumstances describing the object. It is not uncommon to
hear people talk about the "state information" associated with a particular object. For example, the
state of a bank account object would include the current balance, the state of a clock object would be
the current time, the state of an electric light bulb would be "on" or "off." For complex objects like a
human being or an automobile, a

For instance, economic growth is mainly constrained by the policy and political environment, which
indicates that the economic growth momentum is not strongly autonomous. The current
consumption growth will mainly depend on policy guidance and encouragement in the national

consumption of endogenous mechanisms is hard to form. Strategy Figure A The first strategy
attempted by the group involved timing trades based on daily market performance and expectations.
Based on our predictions, shares were bought during the early hours of trading and by mid–day, the
group had a good idea what would be kept until the next day of trading and what would be sold by

little attention was paid to long term potential as the group felt the timeframe the simulation take
place in was too short. This strategy, while mildly successful, was not earning large enough gains for
the group's portfolio. Many of our gains would be negated by the commission the simulator charged

Measuring World Development Essay
Measuring World Development
Development is a complex economic, social and political phenomenon. There are a range of simple
and composite indicators used to measure development. There are many definitions of development,
perhaps the most used is;
"Development refers to a number of characteristics such as demographic change, economic growth,
an increase in the case of resources, modernisation, higher levels of technology and political
freedom."
Indicators of development are put into four sectors: Economic, Social, Political and environmental.
These factors can be broken down into two groups, simple and composite. Such simple indictors
would be birth rate, death rate and GNP. ... Show more content on Helpwriting.net ...
These types of countries are not necessarily 'not developed', they just have different customs,
cultural differences or they could be nomadic (farming based) or an indigenous population, as
described above.
Maps of the globe are produced to show levels of world development based on three key features;
wealth, social advantage and deprivation. An imaginary line can be seen around the world which
separates the 'developed' countries and the 'non developed' countries. This line is called the Brandt
line. It is a modern day method of measuring development. It basically separates countries based on
how economically stable a country is, how technologically advanced it is, how democratic and how
modern a country is. The line shows 'most developed' countries to the north and west, whereas the
'least developed' countries to the south and east. As with every theory, there are exceptions. These
being Australia and New Zealand, which are classed as 'developed' countries.
Other indicators of development that are being used today are the PQLI, which is the physical
quality of life index. Also the IHSI, which is the International Human Suffering Index. The PQLI is
a quantitative measure of development and can be calculated by taking the average of three
variables. These are life expectancy, literacy rates,

Most Types Of Volcanoes Are Shield Volcanoes, Scoria Cones...
1. The major types of volcanoes are shield volcanoes, scoria cones (cinder cones), and
stratovolcanoes (composite). Each of these volcano types is influenced by the volume, the amount of
magma, viscosity, a measure magma's fluid friction, and volatiles or dissolved gases, of the magma
that creates them. Shield volcanoes form from the solidification of lava flows of basalt (Abbott
2014). These large volume, low viscosity, low volatiles magma flows travel great distances. As
thousands of layers of lava flows cool on top of one another other, volcanoes are formed over a long
period of time. The width of these volcanoes is greater than their height, for example Mauna Loa in
Hawaii. Scoria or cylinder cones are low height conical hills formed by basaltic and andesitic
pyroclastic debris collected near a volcanic vent. Scoria cone magma is of small volume with
medium viscosity and medium volatiles. At the top of these cones are summit craters usually less
than two kilometers in diameter which may hold magma lakes during an eruption (Abbott 2014).
Additionally, lava may also drain from the base of scoria cones. Stratovolcanoes or composite
volcanoes are steep sided and symmetrical, examples include Mount Kilimanjaro, Mount Rainer,
and Mount Fuji. The peaks of composite volcanoes are built of alternating layers of pyroclastic
debris capped by high viscosity andesitic to rhyolitic lava flows that solidify to form protective caps
(Abbott 2014). Magma of stratovolcanoes is of high

Use of Composites for Aircraft Primary Structural Components
In today's commercial aviation world, airlines have for a long time understood the importance of
flying an aircraft as economically as possible. Advances in technology have made this possible in a
number of ways, one of which is the introduction of composite material use wherever feasible.
Composite materials typically offer a weight saving of between 20 and 25% when used in place of
historically manufactured components made predominantly from alloyed metals. The heavier the
aircraft, the more fuel it burns for a given mission, making weight reduction top priority for aircraft
designers. The non–corrosive benefits, high–energy absorption and resistance to fatigue offered by
composites are another attractive feature, but despite this and ... Show more content on

This percentage of composite use takes into consideration a new technology used in the A380
manufacturing process. Glass Reinforced Aluminium or GLARE as it's commonly known is a novel
material that combines the advantages of both metals and composites. Used in the A380's upper
fuselage crown, and being less prone to fatigue and more economic compared to pure composite
material, GLARE can be manufactured into structures with little change to conventional techniques.
Figure 3 Composite use on the Airbus A380 4 Boeings latest project, the 7E7 is set to become the
first predominantly composite airliner since the days when aircraft were constructed from fabric and
wood. The company has announced that the majority of the 7E7's primary structure including the
fuselage and wing will be manufactured from composite materials, resulting in composites
accounting for approximately half the aircraft structural weight, a significant increase on the A380.
The decision to use composites to this extent, widely viewed as daring by the industry, contributes to
the efficient theme of the 7E7, with weight savings that allow a 20% less fuel burn for comparable
missions, or a significantly increased range than other wide–body aircraft. Boeing completed
production of the first full scale one–piece fuselage section for the 7E7 in January 2005 (Figure 4).

Imagine flying at 30,000 feet in the air. You are warm, comfortable and possibly have a movie to
watch. But the thought that a small fraction of an inch of material is all that separates you from the
exterior of the plane makes you second guess your security. However, this is all possible thanks to
the power of dreaming and the incredibly efficient use of composites. These materials exhibit unique
properties that lead to an astounding amount of benefits. More than the material itself, it is the team
at Boeing and its suppliers who work together to create one of the world's most innovative planes.
The Boeing 787 Dreamliner uses advanced composite technology to provide an increase in
efficiency, longevity and comfort, as well as a unique manufacturing process that leads to
advantages over both previous models and competitors.
The building materials available to engineers today are vastly improved over those of the past. One
class which has seen wide spread usage in many fields are composites. These new materials first
appeared on the aerospace scene in the early 1970's, for these materials were found to provide many
benefits over the previous metal–based designs.

Photography And The Invention Of Photography
Approaching the turn of the twentieth century, photography was used mainly scientifically, to gather
data and make observations. Aside from some independent portrait work, the camera was not
considered a highly artistic instrument. Cameras were barely given a second look in aristocratic
artistic circles. The idea that photography could not be art met challenges in Britain by the Pictorial
movement, the vision of photography similar in subject to impressionist paintings that aimed to
make viewers emotional. This movement took a heavy foothold at a time when cameras were just
entering the consumer market; later making it's way across the pond to America. It is evident when
comparing the work of Gertrude Kasebier, who photographed in the ... Show more content on

On the other hand Edward Weston transformed simple objects like shells, leaves, and rocks with
heavy shadows and sharp contrast, making intriguing interest (Szarkowski). Both wall–worthy
artists became so effective at making attractive photographs, they earned inspiring expositions at
notable institutions. They helped spur the interest of the general public to view photographs as art
and the camera as an instrument of pleasure rather than one of work. The look of a photograph
during the time was different than anything that came before, and their styles show even in today's
photographs. Especially the work of Weston does not appear "outdated". It complements modern
tastes as well.
Separating Pictorialist Photography for other photographic forms is its emphasis on emotion. A point
was made so audiences would feel connected to the still frames. If a painting could make a old
woman reflect on the happy times in her life or bring out despair in a man who had lost a child, why
couldn't a photograph do the same? To accomplish this, Käsebier pioneered women and domestic
urban situations to evoke emotions in a wide range from lust and pleasure to frustration and disgust,
a particularly marveling feat ("Gertrude Käsebier"). Later, Weston used increasingly abstract scenes,
frequenting landscapes to paint emotions (Szarkowski). The fact that

Case 9-1: Low Nail Company Essay
CASE 9–1: LOW NAIL COMPANY
Question 1: Using the EOQ methods outlined in chapter 9, how many kegs of nails should Low
order at one time?
The EOQ formula is:
EOQ = √ 2 (annual use in units) (cost of placing an order) / annual carrying cost per item per year =
√ 2 (2000) (60) / 2 = √ 120,000 = 345 kegs per order
Note the 2 in the denominator. That is because, on average, the rented warehouse space is only half
full, which, makes the average warehousing cost per keg be $2.
Question 2: Assume all conditions in question 1 hold, except that Low's supplier now offers a
quantity discount in the form of absorbing all or part of Low's order processing costs. For orders of
750 or more kegs of nails, the supplier will absorb all the order ... Show more content on

Question 4: Take into account the answer to question 1 and the supplier's new policy outlined in
question 2 and the warehouse's new policy in question 3. Then determine Low's new EOQ.
The relevant table is as follows: Orders/year | Order size | Processing costs ($) | Warehousing costs
($) | Sum of processing and warehousing costs ($) | 1 | 2,000 | Free | 1,000 | 1,000 | 2 | 1,000 | Free |
500 | 500 | 3 | 667 | 90 | 334 | 424 | 4 | 500 | 120 | 250 | 370 | 5 | 400 | 150 | 200 | 350 | 6 | 334 | 180 |
167 | 347 | 7 | 286 | 210 | 143 | 353 | | | | | |
The new EOQ, based on the above information, is 334.
Question 5: Temporarily, ignore your work on questions 2, 3, and 4. Low's luck at the race track is
over; he now must borrow money to finance his inventory of nails. Looking at the situation outlined
in question 1, assume that the wholesale cost of nails is $40 per keg and that Low must pay interest
at the rate of 1.5% per month on the unsold inventory. What is his new EOQ?
This answer can be done in tabular form as well, with the interest on inventory appearing as a new
column. If one order is placed a year, the average inventory is 1,000 kegs, worth $40,000, with
annual interest charges (1.5 x 12 = 18%) of $7,200. Other interest costs are calculated in a similar
fashion, adjusted for average inventory.

Why Does The Demand Curve When Each Of The Determinant Curve
Q#1. Explain the law of demand. Why does a demand curve slope downward? When the prices
change due to change in supply for a commodity, buyers change the quantity of that item which they
demand. When price drops, larger quantity will be demanded and it rises, a demanded would be of
lesser quantity. The demand curve drops downward because when the price is low people buy more
of product as price is hurdle in between so when hurdle is lower the more people will buy.
Whenever the price for one product decreases from that of other a buyer will shift toward the
cheaper product and even for those which price has not been changed and more can be bought
because of its low or stable price this is the substitution and income effects reinforce each ... Show
Q # 2. What are the determinants of demand? What happens to the demand curve when each of
these determinants changes? The main determinant of demand is the price of the commodity due to
change in prices the movement is made in demand curve known as change in quantity demand.
Lower or decreased price and when there is an increase in quantity demanded it leads to the upward
movement of demand curve so there would be decrease in quantity needed. The determinants of
demand can be a) number of buyers, b) income level, c) change in demand these are the factor
which will result in changing of demand curve A) NO of buyers (also called demographics or
population) Basically when there are more people, the more demand you will have. When the
number of buyers goes up the demand curve will shift right or up and if you have fewer buyers it
will go down. B) INCOME LEVEL When the income level of a nation rises, then the consumption
would automatically increase so the demand curve will shift upward and in the times of recession
the demand curve will shift down. C) CHANGE IN DEMAND These are the number of buyers, the
tastes (or desire) of the buyers for the commodity, the income of the buyers, and the changes in price
their expectation and demand of the product would shift of the entire demand curve to the

While it does say street helmet in the name, this model is really only designed for racing and
competition. The difference between a racing helmet and a road helmet is both the design and the
space in front. Since your child will be breathing heavily during a race, the front is positioned
further out to allow for more air to get in (and out). Also, motocross helmets have no face shield as
they are designed to work with goggles instead.
Speaking of goggles, what I like about the TCMT Helmet is that it comes with both goggles and
gloves, meaning that you don't have to search around for matching gear (just clothes). And when I
say matching, this helmet/goggle/gloves combo comes in six different colors so that your child can
find the look that fits his or her riding style.
As far as safety is concerned, this helmet is highly rated by the DOT and is made of a durable

goggles are UV coated, so they repel the sun well. To further help with the sun, this helmet comes
with an adjustable visor that you can also remove if you ever need to. Overall, this is a great starter

Steel Beams with Timber Webs
INTRODUCTION 1.1 Objective of Proposed Project This project will develop models enabling the
structural design of steel beams with timber webs (SBTW). The beams analyzed will have three
configurations: an I–Beam type where the steel flange width, bf, is greater than the timber web
thickness, tw; a Box Beam configuration where the steel flange width is equal to the timber web
thickness; and an Architectural Beam style where the steel flange width is less than the timber web
thickness and the steel flanges are totally encapsulated within the timber web. The three beam styles
are shown in Figure 1. The physical properties of steel beams with timber webs structures are
expected to be highly influenced by the nature of the connection between steel and timber. However,
the knowledge of the macro–mechanical properties of glued steel–timber joints is still limited. The
work to be performed intends to increase the body of knowledge on this subject. This research study
was fomented by the desire to reduce the aspect ratio of long span glued laminated beams.
Additionally, the architectural style beam has the possibility of providing the necessary fire
protection for the steel while being an extremely aesthetic alternative for exposed structures. The
steel beam with a timber web would also be a good candidate for stringer highway bridges with a
glulam deck intended for secondary roads. These bridges could be rapidly installed with a minimum
of skilled labor decreasing road closure

Comparing The Outrigger System And Braced Frame System
2.2 Braced Frame and Shear–Walled Frame System
Rigid frame systems are not efficient for buildings taller than 30 stories, because lateral defection
due to the bending of columns causes the drift to be too large. On the other hand, steel bracing or
shear walls with or without rigid frame (brace systems and shear wall systems), increases the total
rigidity of the building and the resulting system is named as braced frame or shear–walled frame
system. These systems are stiffer when compared to the rigid frame system, and can be used for
buildings over 30 stories, but mostly applicable for buildings about 50 stories in height. However,
there are examples for these systems reaching over 100–storey ... Show more content on

As an innovative and efficient structural system, the outrigger system comprises a central core,
including either braced frames or shear walls, with horizontal ''outrigger'' trusses or girders
connecting the core to the external columns. Furthermore, in most cases, the external columns are
interconnected by exterior belt girder. If the building is subjected to the horizontal loading, the
rotation of the core is prevented by the column–restrained outriggers. The outriggers and belt girder
should be at least one and often two stories deep to realize adequate stiffness. Thus, they are
generally positioned at plant levels to reduce the obstruction they create.
Depending upon the number of levels of outriggers and their stiffness, the perimeter columns of an
outrigger structure perform a composite behavior with the core. When compared to single–storey
outrigger structures, multi–storey outriggers have better lateral resistance, and thus efficiency in the
structural behavior. However, each extra outrigger storey enhances the lateral stiffness, but by a
smaller amount than the previous
