The Synthesis Of Nmofs And Other Ligand And Metal...
NMOFs from the Gd and BHC shows that it is possible to process unique NMOFs from the same
ligand and metal combinations by utilizing the multipurpose metal–ligand coordination modes.
The solvothermal approach for the synthesis of NMOFs was reported by two scientists. In their
research, they avidly investigated the transformation of the particle morphology during the synthesis
process. They added N, N–phenylenebis (salicylideneime) dicarboxylic acid solution which was in
DMSO to DMF solution which composed of two equivalents of Zn (OAc) 2. They observed that one
equivalent of zinc ions coordinates to the pocket of the salena and the remaining zinc ions
equivalent coordinates to metalloligands. They further heated the resulting solution at 120℃ for
thirty minutes. As the heating proceeded they discovered that the nanowires were changing into
nanocubes through the intrastuctural fusion and accumulation. They discovered that by varying the
reaction conditions they were capable of tuning the cubes' sizes. The smaller nanoparticle cubes
were obtained by reducing the solubility of the nanowires via application of poor solvent mixture or
lowering their temperatures.
Uses of the nanometer–sized coordination polymers
It is well known that nanometer–sized coordination polymers can be manufactured from diverse
organic bridging ligands and metal ions, therefore, can be used to made different materials with

The Effects Of Heavy Metal Decontamination Of Sluil
Heavy metal contamination of soils has received considerable attention in the contemporary science.
Application of biological processes for decontaminating the contaminated/polluted sites is a
challenging task because heavy metals cannot be degraded and hence persist in the soil (Kidd et al.,
2009; Lebeau et al., 2008; Maet al., 2011a; Rajkumar et al., 2010). Among heavy metals, Al
(aluminium), Zn (zinc), Mn (manganese), Cr (chromium), Cu (copper), Cd (cadmium), Pb (lead)
and Hg (mercury) are the common toxic metals (Emamverdian et al., 2015). Cadmium (Cd) enters
the soils in various ways, but mainly through anthropogenic sources such as phosphate fertilizers
and sewage sludge, and emissions from power stations, metal and cement ... Show more content on

In order to cleanup the contaminated sites, heavy metals should be extracted and concentrated by an
appropriate technique for proper disposal in designated secure landfill sites. The established
conventional techniques (e.g., thermal processes, physical separation, electrochemical methods,
washing, stabilization/solidification and burial) for clean–up of metal contaminated soils are
generally too expensive and often harmful to soil microbial diversity (Dermont et al., 2008; Ma et

Metal-Only Lewis Pairs with Transition Metal Lewis Basas
Metal–Only Lewis Pairs with Transition Metal Lewis Basas
Introduction:
History of Metal–Metal Dative Bonding Concept In 1961, Vaska and Diluzio synthesized a lemon–
yellow compound known as the organometallic complex trans–[IrCl(CO)(PPh3)2]. This was
achieved by reducing iridium(III) to iridium(I) using just triphenylphosphine and an alcohol. This
was significant because they had prepared an iridium carbonyl complex without the use of carbon
monoxide. This complex has reversible dioxygen coordination, but more importantly, it is extremely
reactive with acids, halides, and dihydrogen yielding stable Ir(III) addition products. The discovery
of this Iridium complex meant that laboratories across the globe could now easily create, in one step
and several hours, an air–stable compound that could undergo oxidative addition reactions. Also, the
reaction could be monitored by watching the carbonyl C–O stretching band in the IR spectrum and
NMR spectroscopy later on. Because Vaska's complex was so stable, its reactivity was limited. The
complex serves as an excellent molecular platform for defining how oxidative addition reactions
make homo– and heterogeneous catalysis a reality. While the term "oxidative addition is a staple in
inorganic chemistry and catalysis, the step transition metal Lewis basicity is almost never seen.
There are numerous methods that a metal can cleave an element–element bond, from concerted,
side–on cleavage to backside attack. Most oxidative addition

Taking a Look at Heavy Metals
Heavy metals are elements that exhibit metallic properties. It mainly includes the transition metals,
basic metals, some metalloids, lanthanides, and actinides. Many different definitions have been
proposed–some based on density, some on atomic number or atomic weight, and some on chemical
properties or toxicity (Duffus, 2002). Example for some heavy metal are iron (Fe), zinc (Zn), copper
(Cu), lead (Pb), mercury (Hg), cadmium (Cd) etc.
Iron is important as a mineral in human body (part of haemoglobin) and also part of many enzymes
and proteins. Deficient amount of iron in human body will cause anaemia while excess amount of
iron may cause iron poisoning or hemochromatosis. Zinc is a metal which known as essential trace
element as very little amount of it is necessary for human health. Zinc is important for cellular
metabolism, catalytic activity of enzyme, immune system, synthesis of protein, wound healing, cell
division and DNA synthesis (Sandstead, 1994; Solomons, 1998; Prasad, 1995). However, excess
amount of zinc may lead to remarkable health problems such as depressed immune system, stomach
cramp, vomiting, nausea and anaemia and skin irritation.
Cadmium (II) ions are known of its toxicity in trace amount may result in poor health effect.
Cadmium can be found easily in contaminated food or water. Workers of metal refining or smelting
factory or cadmium product manufacturing have a high possibility to be exposed to cadmium. Long
term exposure of cadmium lead to

Explain How Different Metals React In Different Anion...
How do different metals react in different anion solutions? After the experiment was conducted it
was very clear on which metal was most reactive in anion solution and which was not with watching
the reaction occur. It is clear that zinc and silver nitrate had the slowest reaction as it was creating
rust on the metal. The chemical equation for zinc and silver is, Zn+Pb(NO3)–Zn+Pb(NO3)2.
Magnesium put in lead creates the quickest reaction. When it had reacted it had a thick layer of lead
which brings the magnesium to the bottom. When taken out of the water the magnesium
disintegrates. The chemical equation for magnesium and lead is Pb+Mg(NO3)2–Pb+Ag(NO3)2.
With using the activity series of metals it helps determine which metal has the highest

Precious Metals Research Paper
Precious metals do not have their own group on the periodic table. They are arranged together on the
table. These elements do have the same chemical properties, however they do not have their own
classification. All of these metals do not rust, they are resistant to oxidation and corrosion and they
only break down when they are in high temperatures. Gold (Au), silver (Ag), platinum (Pt),
ruthenium (Ru), rhodium (Rh), palladium (Pd), iridium (Ir), and osmium (Os) all have similar
properties and are considered to be precious metals.1
Many of these elements were found in platinum ores. Scientists used aqua regia, an acid that can

The only elements that were not found in this process was gold and silver. These two metals were
known since ancient times. If they were to use aqua regia, then the pure substances of gold and
silver would be extracted from the ore.
Platinum was discovered by Antonio de Ulloa in 1735. Ulloa established the first mineralogy lab in
Spain and was the first to study platinum. Platinum was first recognized as an element in 1774 when
Charles Wood isolated the ore with aqua regia. Then the pure form of platinum was found in the
residue. However, there were more than one substance that was unknown in the residue. Hippolyte–
Victor Collet–Descotils believed that there was an unidentified metals that caused the red color of
some platinum salts. In 1803, William Hyde Wollaston investigated this by first dissolving the crude
platinum ore in aqua regia. Then he was able to get to the platinum metal by dissolving the solution
in ammonium chloride. The liquid which remained had properties which matched no known
substance. Wollaston named it Rhodium. This was not the last element that Wollaston discovered
that year. He used aqua regia to dissolve the platinum ore and isolated

they have a paranoia that it is evil. "Kids who wear black and listen to rock music aren't all satan
worshippers or terrible people."~Andy Biersack. There is no reason that this music shouldn't be

Where did the misconception that rock and metal bands have meaningless lyrics come from? In fact,
rock and metal bands tend to have deeper and more relatable lyrics than some(not all)songs that
everyone seems to enjoy. An example is that one set of lyrics in a black veil brides song called never
give in is " Never give in, Never back down. When your life seems lost, fight against all odds."

What Are Non-Ferrous Metals?
Non–ferrous metals were the first metals used by humans for metallurgy. Gold, silver and copper
existed in their native crystalline yet metallic form. These crystals, though rare, are enough to attract
the attention of humans. Less susceptible to oxygen than most other metals, they can be found even
in weathered outcroppings. Copper was the first metal to be forged; it was soft enough to be
fashioned into various objects by cold forging, and it could be melted in a crucible. Gold, silver and
copper replaced some of the functions of other resources, such as wood and stone, owing to their
ability to be shaped into various forms for different uses.
Due to their rarity, these gold, silver and copper artifacts were treated as luxury items and

They are formed when in a melted or gelatinous phase. They are heated, formed, and then cooled in
their final shape.
Advantages: Thermoplastics have a decent range of properties and are energy efficient each in their
manufacture and process. Thermoplastic parts are often created in very high volume with high
preciseness and low cost. Thermoplastics may replace metals with a substantial weight savings,
providing correct care is taken in its design. Most thermoplastics have better fatigue properties than
metals and can tolerate larger deflections than metals without deforming.
Disadvantages: Thermoplastics melt. Some degrade in direct sunlight or underneath high U.V. light
levels. Several materials have poor resistance to hydrocarbons, organic solvents, and extremely
polar solvents however others have great resistance to those materials. Thermoplastics suffer from
creep, a relaxation of the material from long term loading. Several thermoplastic materials,
particularly composites, tend to fracture instead of deform beneath high stress levels.

The Effect Of Metal Chelation On Latin
Introduction
Chelate means claw in Latin. Metal Chelation is a process when a polyvalent metal ion form
covalent bonds with a drug and binds tightly to form a 5 or 6 membered ring. 5 and 6 membered
ring structure are very stable because their bond angle has no ring strain. Thus, when a compound is
chelated, it will not be able to pass through the biological membrane, in another words, it will not be
metabolise by the body but to be pass through the renal without being absorbed and being excreted
though urine. Essential metal such as magnesium, iron, calcium and zinc are easily found in many
food source and is vital to be included as part of our diet as these trace elements are helping our
body enzymes, hormones and cells to work. Insufficient intake of trace minerals can cause
symptoms of nutritional deficiency. (Glusker,1999) At certain times, these metal are also use as an
active ingredient or excipients in pharmaceutical industry.
Chelation of Alendroic Acid with Calcium
Alendronic acid is a bisphosphonate drug that is used to inhibit osteoclastic bone resorption .it
works by attaching to hydroxyapatite binding sites to impair the ability of the osteoclasts to produce
the protons necessary for continued bone resorption. It also inhibit osteoclast activity by promoting
osteoclast apoptosis. (pubmed ) Patient group who are mostly taking this medication are

Identifying The Identity Of Two Unknown Metals Essay
Introduction
It is necessary to identify the identity of two unknown metals. This is important because a metal
scrap yard must know the identities of the metals before they can be recycled. It is also necessary to
know what each metal is if a building is to be made using one or more of these metals. Identifying
the metals will be done using intensive properties. Intensive properties do not depend on the amount
of material present. Density is an intensive property found with the formula D=m/v. Which is
defined as mass divided by volume to find the density.
Procedure
First, each metal's description and weight was recorded. Additionally, the weights of each cylinder
used was recorded. Next, a graduated cylinder was filled with 20mL of water and unknown metal II
was fully submerged in the water 3 times. Each time, the volumes were recorded and the difference
between the final volume and initial volume was calculated. This test was repeated for unknown
metal IV.
Calculations
Unknown I and V Masses
Unknown I was weighed 3 times in a graduated cylinder with 20 mL of water in it. Weight 1 came
out at 215.672g, weight 2 came out at 216.135g, and weight 3 came out at 216.362g. Averaging the
weights gave 216.056g.
Unknown V's weights came out at 74.065g, 74.623g, and 74.538g. Averaging the 3 weights yielded
74.589g.
Unknown I and V Volumes
Unknown I's 3 volume measurements came out to be 26.26 mL, 26.25mL, and 26.02mL. Averaging
these volumes yields 26.15mL.

Metal Reactivity Series Lab 2015
Teaghan Hignett March 15, 2015 Mr. Cho SCH3U Metal Reactivity Series Lab 2015 Question:
What is the relative reactivity of aluminum, potassium, copper, iron and hydrogen? Introduction:
This lab will introduce several key concepts surrounding metal reactivity as well as electronegativity
and periodic trends on the periodic table. Electronegativity by definition is a measure of the
tendency of an atom to attract a bonding pair of electrons. In a bond between atoms in a molecule,
the atom that is more electronegative will attract the bonded pair of electrons closer to it's own
nucleus. Reactivity refers to how vigorously or the likelihood of a element to react with other
elements or substances. Electronegativity can be used to determine the reactivity of a substance as
well as using ionization energy (how easily electrons can be removed from an outer shell). This lab
will allow us to look into the relative reactivity of metals. Relative reactivity means the reactivity
scale in order of decreasing reactivity between the 5 metals chosen above. The tests that allow us to
build a reactivity series for metals use Single Displacement Reactions. When performing these tests,
the substances will only react if substance A is more reactive than substance B. If no reaction occurs
than substance B is more reactive that A. This happens because A and B are cations and the X is
what will bind with either A or B and X is also a anion. Anions will only switch cations if it benefits
them

It's cheaper than using copper, but will cost more than using steel. The biggest drawback with
aluminum is that the metal is soft, so it should be avoided in areas that have flying debris or high
winds that cause impact damage to a roof. The material does weigh much less than other metal
roofing materials, so it does tend to be installed faster and easier than copper or steel.
Aluminum will hold up well in climates that have a lot of rain, since the material will not corrode
like other types of metal roofing. You can purchase the material in shingles or sheets, which are
usually painted after they are installed to improve the overall aesthetics of the roofing material. This
will require additional maintenance over the years to give the material another coat of paint.
Copper Roofing
One of the most expensive metal roofing materials will be copper, but many homeowners go with it
because it's unique and beautiful in its appearance on a home. The material is also incredibly durable
with it being hard to damage, and it will not require any maintenance or cleaning after it is installed.
This makes it great for large homes that create difficulties when trying to access the roof.
A unique attribute of copper is how it is a heavy and thick roofing material, and its size won't
change when facing extreme heat in the summer. The material also changes color as it gets older to a
green–blue hue, called the patina process, which is an aspect of it that many people like.

Metal Heads : The Pioneers Of What We Now Call Thrash...
Metal music has been around for several years. It dates back to the early 1980's. Bands like Venom,
Celtic Frost and Kreators are the pioneers of what we now call Thrash Metal. When these fathers of
the genre emerged, so did a name that would label them for years to come. The term 'Metal Head'
has been rumored to have been created by the Vikings back in the 5th century who wore a cap with
two metal horns on their heads. Metal Heads receive a lot of negative backlash and go through a lot
of turmoil when it comes to lifestyle and music choice. Metal heads in today's culture are perceived
and looked at as drug addicts and alcoholics. That they all ride Harley Davidson's and attend wild
riot worthy parties. The critics say that all metal heads are satanic devil worshippers and racists who
listen to the music for a message to spread hate and violence amongst other cultures and the youth.
In this article, I will be explaining to the audience that metal heads come in all shapes and sizes and
should not be judged for how they express themselves. That not all stereotypes are true and can be
hurtful. A perfect example of the inconceivable stereotype is my boss. Her name is Jennifer Mica
and she is a hard–core death metal fan. What makes her completely opposite from the accusations is
her small stature. She stands at 4'11 and does not bear a full beard like the stereotypical metal head.

Cast iron, the great material of the Industrial Revolution, revolutionized Georgian and Victorian
buildings. The protection of metal includes galvanizing, tern plating, plating and anodizing.
Galvanizing protects metal or steel against the exposure to the atmosphere and rusting. It is applied
by an application of zinc coating. Tern plating is a steel sheet with a coating of tern metal which is
an alloy of led and tin. This is applied by dipping the steel into molten metal. An example of what
you would use tern plating for would be roofing, gutters, gas tanks, oil cans, etc.. Another way to
protect metal is plating. Plating is the coating of metal or other material such as plastic or china,
with a hard, nonporous, metallic surface to improve durability. Most plating is done for decorative
purposes, but still more is done to increase durability and corrosion resistance. An example of where
you would use plating would be on auto parts, housewares, hardware, plumbing/electrical
equipment and machine tools. Anodizing is another method of protecting metal. It is a method of
coating metal for corrosion resistance, electrical insulation, thermal control, abrasion resistance,
sealing, improving paint adhesion, decorative finishing. This is applied by electrically depositing an
oxide film onto the surface of a metal usually aluminum. Aluminum, after it has been anodized can

The Effect Of Mineral Nutrition On The Toxicity Of Metals
There is a vast amount of literature which indicates that the mineral nutrition has an important role
in the toxicity of metals (Pond and Walker, 1972, 1975; Larson and Piscator, 1971; Petering et al.,

Waldron and Stofen, 1974). It is true, especially to those micronutrients which are essential such as
zinc, copper, iron with respect to toxicity of certain metals like cadmium, arsenic, lead etc. It is
assumed that the dietary intake of metals in excessive such as copper, iron and zinc will be
protective against the toxic effects of the heavy metals like lead. The deficiency of calcium and
other essential elements result in the enhanced toxicity of lead and cadmium [ref]. There had been
difficulty in evaluating the role of essential nutrients like zinc, iron, copper etc on the toxicity of
heavy metals, perhaps due to differences in the animal models choosen, the route of administration
and other metabolic and physiological differences which leads to variable results between studies.
Lead zinc relationships
Cerklewski and Forbes (1976) reported that rats when fed a diet having low levels of zinc and
containing 200 ppm of lead cause a marked increase in the lead levels of tibia and urinary 8–
aminolevulinic acid (ALA). Further it has been observed that the lead levels of tibia and urinary
ALA has reduced greatly when the zinc content of the diet was raised to optimal or super–optimal

Disadvantages Of Metal Roofing
As a Construction Economics student, you need to be aware of the different types of materials used
during the construction process. The purpose of this tutorial is to explain what we encountered
during our site visit.
Roofing plays a very important part of a building, not only aesthetically but structurally. There are
many different types of materials used for roofing systems.
Timber is one of the materials that is most commonly used in construction. Timber is one of the
most environmentally friendly building materials available. It is extraordinarily versatile, naturally
renewable, beautiful, and light and strong to build with. It is also a high performance, lightweight
material that possesses incredible load bearing and thermal properties. Wood is also prone to ...

Mercury: Transition Metal
Mercury is a transition metal that is also known as "quicksilver." No one is sure who discovered this
element. Mercury has been used since ancient times; the Chinese, Egyptians, and the Hindus have
been known to use mercury. In 1500 B.C. mercury was found in ancient Egyptian tombs. There also
has been writings found that have said "liquid–silver" and "water–silver" written by Aristotle in the
fourth century B.C. The Greeks referred mercury as hydragyrum. The romans modified this name to
Hg which is how we got the element symbol for mercury. The modern name for this element came
from the alchemists. They got this name by observing the element's rapid, liquid flow and then
named it after the fastest moving planet, mercury. Mercury is a highly

Extraction of Metals
Extraction of metals
The History of Metals.
Metals have been used by people for many thousands of years. Gold and silver, found as native
metal, were used both as jewellery and as a status symbol – nothing new there. These metals were
known in the Stone Age, but gold and silver are too soft to be used as tools.
The first really useful metal to be discovered was bronze. This began the Bronze Age. Bronze was
used extensively for tools and weapons in Asia and Africa from 4,500 B.C. (6,500 years ago) and in
Britain from 2,000 B.C. (4,000 years ago). News of the new material travelled slowly in those days
and it took the Brits 2,500 years to get the message.
Bronze is not an element (like gold and silver) but an alloy (metal mixture) of ... Show more content

The same can be said of metal extraction. Metal extraction can drastically affect the quality of air in
the surrounding areas, what with the high levels of dust and gas in the area. There's also the noise
pollution that it creates, which is affecting the natural habitat of animals. Last, metal extraction
disfigures the landscape.
Now, if companies continually extract metal, the land will forever be disfigured, causing flooding
and soil erosion in the area. It will also cause large–scale natural habitat destruction, causing so
many species to be uprooted. There's also the air and water pollution to consider.
Economic Impact of Metal Extraction
It is a fact that mining, extracting, refining, and purifying metal will cost a lot of money. There are
different types of metal, and they need different methods of extraction. Now, the methods of
extracting metal do not come cheap, nor does refining and purifying metal. Not only will you need
special equipment for their extraction, but you will also need other elements as well such as copper,
zinc, mercury, among others, for the purification and refinement processes. Some of these elements
are very harmful and toxic not only to humans and animals but to nature as well, worsening the
environmental impact of metal extraction.
Aside from this, you also have to think of the transportation costs of extracted metal.

In the gravimetric analysis experiment, the Molar Mass of M2CO3was 78.125 g/mol. The
percentage error of the Molar Mass is calculated as follows:
78.125 – 73.89173.891x 100 % = 5.73 %
In the simple weight experiment, the Molar Mass of M2CO3was 65.08 g/mol. The percentage error
of the Molar Mass is shown as follows:
65.08–73.89173.891x 100% = 11.92 %
The Molar Mass of the following metal carbonates are
Li2CO3= (6.94 x 2) + 60.01 = 73.89 g/mol
Na2CO3= (22.99 x 2) + 60.01 = 105.99 g/mol Percent error is 26.31% for method 1 and 38.63% for
method 2
K2CO3= (39.10 x 2) = 138.21 g/mol Percent error is 46.54 % for method 1 and 52.91 % for method
2
As shown in the calculations above, the unknown substance that was provided at the beginning of
the experiment is closest to Lithium with percentage error of only 5.73 % for the first method and
11.92 % for the second method.
For the first method used, the calculations done are:

Full Metal Jacket Movie Analysis
Before watching the movie Full Metal Jacket, I thought it would be more of a comedic type of war
movie. This movie portrayed the sad part of war, where you lose your closes friends, and shows how
gruesome and cold war could be. In today's society, video games only portray the positive stigma of
war instead of showing the negatives and dark part of it.
My favorite scene of the movie was from the opening of the film to the first meeting between the
U.S Marine Corps recruits and the senior drill instructor Gunnery Sergeant Hartman. The reason I
enjoyed the beginning scene is because it had a lot of dark comedy where he was hazing the recruits.

killing heartless monster, which is what the film is trying to show as the theme. In the first part of
the film, Private Pyle was the least athletic, and overweight recruit who could not be on par as the
rest of the recruits, in the second half of the film I saw a very different Private Pyle; he put Sergeant
Gunnery Hartman words into his head and became a maniac

The Effects Of Transition Metals
Transition metals, such as iron, copper, zinc, nickel, and cobalt, play vital roles in numerous
67 biological processes. Because of these metals' unique redox and inorganic chemical properties,
68 they either serve as catalytic centers for enzymatic reactions or contribute to overall protein
69 stability. To thrive, all organisms have to maintain adequate levels of transition metals for their
70 cellular metalloproteins, which account for more than 30% of all proteins in biological systems.
71 However, the overloading of transition metals will cause severe adverse effects, such as
72 generating toxic free radicals. Consequently, biological systems have evolved sophisticated
73 mechanisms for metal acquisition, transportation, storage, and ... Show more content on

All these pathways are vital to bacterial virulence.
92
93 Nix and Nik pathways either directly import nickel by a high–affinity metal transporter or
94 use small–molecule chelators from the environment to mediate metal transportation and have a
95 strong preference for the acquisition of nickel over other metals. In contrast, the Cnt pathway
96 itself synthesizes a novel broad–spectrum nicotianamine–like metallophore staphylopine (STP)
97 from the first three genes cntKLM in the pathway to facilitate metal acquisition and it has little
98 preference for different metals (17–20) (Fig. 1). The biosynthetic pathway of STP is conserved
99 across various pathogens (20). In addition to the STP biosynthesis genes, the cnt operon
100 possesses an STP exporter encoded by the cntE gene and an STP/metal importer encoded by the
101 five genes cntABCDF (17, 20) (Fig. 1). The CntA protein of the importer complex is an
102 extracytoplasmic solute–binding protein and plays a primary role in STP/metal recognition and
103 importation initiation. CntBC are two membrane proteins that form an integral channel to
104 transport STP/metal released from CntA. CntDF are two membrane–associated nucleotide–
105 binding proteins that provide energy for the transportation. Previous independent genetic studies
106 targeting cntA and cntE have demonstrated the importance of both genes for bacterial virulence,

Heavy Metals And Its Effects
1. Introduction
Heavy metals and their salts (Cu, Zn, Hg, Pb, Co, Ni,) are widespread industrial pollutants. In the
waters they come from natural sources (rocks, the surface layers of soil and groundwater), the
wastewater of many industrial enterprises and rain (polluted with smoke emissions). Heavy metals,
as trace elements, are constantly encountered in natural waters and aquatic bodies depending on the
geochemical conditions.
Heavy metals are quite stable and cannot be destroyed. Entering the ponds, they are included in the
cycling of matter and subjected to various transformations. Inorganic compounds are rapidly
solubilized in water and transferred into poorly soluble hydroxides, carbonates, sulfides and
phosphates. Later, these insoluble products settle down and contaminate the bottom sediments.
Under the influence of living organisms (bacteria, fungi and others) mercury, tin, and arsenic
undergo methylation, becoming more toxic alkyl compound. Moreover, metals can be accumulated
in various organisms and incorporated in the food chain and cause poisoning.
This project focuses on the elimination of cobalt (II) metal ions from contaminated waters. Even
though Co (II) appears to be one of the essential elements to human body at low concentrations,
when cobalt is too concentrated; it may damage human body and may cause diseases such as asthma
and pneumonia1. Cobalt pollution may be caused by many alloys (super alloys in gas turbine of
aircraft engines, corrosion resistant

The Use Of Metal Detectors In School Shootings
School shootings have been on the rise in the United States since the early 80's, questioning the
safety and security of schools all across the country. Lots of ideas have come up for trying to keep
weapons out of schools but the idea of having metal detectors has stuck and on paper seems to be a
viable option for schools but in real use they have lots of issues. One of the biggest problems with
using metal detectors in public schools will be cost. Cost affects many different things to do with the
metal detectors, two of the major factors being proper trained staff and paying for repairs. Another
issue with metal detectors are they are slow, make kids late to class and also make kids dread going
to school in the morning. There could be compromises made like alternative options like random
checks or quick pat downs but getting rid of this style of security would be better all together. Metal
detectors should not be used in schools because they make students late to class, cause anxiety and
are too expensive to be used in public schools. Metal detectors are making kids tired and late to
class because the process is so lengthy. Ms. Dunley, a teacher who works at a school where metal
detectors are being used says "She marks several people late everyday because they are being held
up by the metal detector". The time that is being consumed by the metal detectors not only wastes
class time but kids have to arrive hours before school to wait in line to get passed the metal

Copper : The Most Valuable Metal Valued More Than Gold
Aluminium is one of the newest metals to be found only discovered in the 19th century with
developments in chemistry and electricity. The late discovery compared to other commonly used
metals is due to the fact aluminium does not occur naturally in its purest form. Because of this
aluminium was very rare making it a precious metal valued more than gold. Nowadays aluminium is
the most abundant metal elements on earth consisting of 8% of the earth's crust. About 41 million
tons is smelted each year and therefore is used in a wide range of applications. From auto bodies to
food and beverage storage eg: soda cans as well as electrical cables to aircraft skins, aluminium is a
very big part of our everyday lives.
The Extraction of Aluminum
Because aluminium doesn't occur in its purest form the production of it relies on the aluminium
oxide (referred to as alumina) from the raw material bauxite. Bauxite is a clay like soil which is
regularly found near the earth 's surface, normally bauxite contains about 30–60% aluminium oxide
(see picture to left). Producing aluminium consists of two parts, the extraction of alumina from the
bauxite and the smelting of alumina to form aluminium.
Once the bauxite is extracted from the earth's crust it is transported to plants where it goes through a
separation process, usually a process called the Bayer Process (Hall–"Heroult method). This
involves crushing the bauxite using grinders to form a powder before mixing it with water to form a

The Metal Band
Many people give the thrash metal band Metallica the cold shoulder whenever they hear their name
in conversation. Most go right to thinking of The Black Album and how it worked its way onto the
radio waves, and that Metallica is a run–of–the–mill metal band that got lucky by writing a more
mainstream album. However, since the early 1980's they were already fairly well known around the
world even having not really written songs appropriate for radio play. Most fans of the band before
their mainstream approach can be found online scolding them for this very reason. Metallica
symbolized the idea that someone could be successful without compromising themselves, or "selling
out". This was in part why so many could familiarize with their music. ... Show more content on

Already being known, Metallica moved its center of operation to San Francisco. This was where
they began to set up an enormous underground fan base. Having the advantage of coming first
before most thrash bands and also releasing albums before most of them were on the map meant
great success. By 1984 Metallica had already released "Kill 'Em All" and "Ride the Lightning" and
later that year signed with Elektra Records. By 1988 Metallica released "...And Justice for All" and
by that time their underground fan following was colossal. Also, having the song "One" from that
album made into a music video aided in their media coverage. This song had been the first true song
of theirs to be heard on mainstream radio stations. By the arrival of "The Black Album" Metallica
was huge of course, but wanted to take it a step further. They changed their sound and abandoned
almost all of their thrash metal roots to a majority of songs that were radio–friendly. The shorter–
length songs as well as prevalence of ballads made it a commercial success. Many of their hardcore
underground fans felt that Metallica had turned their backs on their fan base and were now a
mainstream heavy metal act. Older records still sold quite well due to their choice to continue
playing their songs at live events. Some of the raised interest in their previous albums was also due
to many people now discovering Metallica from The Black Album. Metallica

Norwegian Black Metal
Norwegian Black Metal Music has a lot of ability to affect human emotions in special ways among
the arts. Music can connect people to one another, and it can also connect people to whatever they
hold sacred. Geertz wanted to know how religion function in a society. To him, religion consists of
symbols that had meanings for ideas, values and lifestyles of a society. Black metal is one of those.
In this, I will be discussing how Satanism came into a music genre call black metal that was started
in Norway and how it is a movement and not a controversy like most people think. Norwegian
Black Metal is a sub genre of heavy metal, which was started in the 1980s in England. It received its
name from a band called Venom when they released their second album called "Black Metal" and its
lyrics focused on anti–Christian and Satanic themes. Black metal is a synonym for "Satanic metal"
because they express harsh anti–Christian and other anti–religion views. They then influenced a lot
of other bands to take after what they were doing. They influenced one of the major bands called
Hellhammer. Everyone said they made raw and vicious music with Satanic lyrics that later
influenced the black metal. They influence a lot of main bands, Mayhem and Darkthrone. Some also
believe that Euronymous goes their name from Hellhammer's track Eurynomos. "Ever hear of
Euronymous, Count Grishnackh or Hellhammer? Maybe not? What about Mayhem, Darkthrone or
Burzum? Is there a light then? Or maybe eight

Plato 's The Republic : The Myth Of The Three Metals Essay
In Plato's The Republic, Plato uses a central story, the myth of the three metals, to illustrate his ideas
as a whole. The myth of the three metals is based off of the story that Mother Nature invented all
human beings and created these human beings by utilizing different metals. The three metals utilized
were gold, silver, iron or bronze. From these metals, each person was born into the role they would
presume in society. Gold represents the guardians, who are governed by reason, making them
suitable to rule. Silver depicts the auxiliaries, who are guided by spirit, predisposing them to be
guards. The final metals are iron or bronze, which share the same traits. Iron or bronze displays the
farmers and other craftsmen, who are led by their appetites, creating the physical laborers in the
society. Plato believes that the myth of three metals will create the perfectly ideal society, that also
allows people to realize what being just means. Work on thesis statement
Throughout Plato's explanations, he utilizes the myth of the three metals to provide justification for
the class system which he believes will create a perfect society. As Plato idealizes, each metal
represents a specific class in society. ""Appropriately so. Nevertheless, listen to the rest of the story.
"All of you in the city are brothers," we'll say to them in telling our story, "but the god who made
you mixed some gold into those who are adequately equipped to rule, because they are most
valuable.""

Abstract
The present study was taken up to identify trace metals as well as to assess the extent of
anthropogenic inputs into the Shimoga area. The Kallur mandli and Sagar road industial estate of
shimoga in and around collected sediment samples from ponds, channel and, river for present study.
The samples were analyzed heavy metals Viz., Cd, Pb, Ni, Zn, Cu, Mn and Fe. The obtained results
are compared with non–polluted sediments of near gadikoppa pond sample, which is away from the
industrial activity for used as back ground values. The study area samples exhibits higher
concentration of Cd, Pb, Ni, Zn, Cu, Mn and Fe than the unpolluted values. Thus, industrial activity
has allowed the accumulation of certain heavy metals by transportation and deposition into
surrounding area of pond, channel and river sediment matrix. The contamination of the sediments
with metals at few locations is attributed to industries and other anthropogenic causes.

Release of Heavy Metals in the Environment
Release of heavy metals in the environment is one of the major pollution problems. Day by day
concentration of these metals is increasing in water supplies due to various industrial processing.
Different industries such as steel manufacturing, fertilizer and pesticide industry, leather tanning,
electroplating, metallurgy, mining and smelting of metalliferous, surface finishing industry, energy
and fuel production industries, electrolysis, electro–osmosis, photography, electric appliance
manufacturing, metal surface treating industries are mainly responsible for releasing heavy metals
into the environment , effluents of these industries are mainly loaded with heavy metals ions.
These heavy metals are very toxic for all living organisms even at very low concentration. Most
common examples of heavy metals are Zinc, Cadmium, Chromium, Arsenic, Lead and Copper.
Heavy metals are classified in three categories on the basis of nature of metal and its value and these
metals have higher specific weight usually more than 5.0 g/cm3 (Bishop, 2002; Volesky, 1990;
Wang & Chen, 2006).
1. Toxic heavy metals including Cr, Pb, Zn, Hg, Cu, Ni, Cd, As, Co, Sn, etc.,
2. Precious metals such as Pd, Pt, Ag, Au, Ru etc.
3. Radionuclides such as U, Th, Ra, Am, etc.
Extensive research has been done in previous years for the detoxification of heavy metal ions.
There are mainly three methods available for the removal of heavy metals physical, chemical and
biological.
Chemical precipitation, ion

Metal Music In The 1940s
In the 1980s there was a seeming uprise of various musical movements branching off from rock
style music. At this time there were many who gained attention by favoring pop rock music. There
were bands Like Rainbow, Uriah Heep and Judas Priest who considered themselves Metal music
however they seemed to favor commercial rock music to gain popularity and stay on the radar. And
then there was a slowly rising act that was "underground" for most of the late 1970's to early 1980's.
This underground movement was known as the "New Wave of British Heavy Metal" (NWOBHM).
Many of these bands played in local areas and venues in hopes of gaining money while having fun.

huge impact on what was known heavy metal in 1980s. Their mascot "Eddie the Head" became an
iconic symbol associated to heavy metal. Even inspiring new artist to create mascots of their own.
The font used to write their band logo is often used as well as a pop culture icon when referring to
things heavy metal. Their Fast paced music called for the creation of people known as "headbanger"
given the title for their iconic headbanging motion when listening to rhythmic and fast paced music.
This movement of headbangers created a culture of Metal fans wearing vulgar clothes and violent
shirts to create a sense of intimidation. The rise of headbangers lead to the making of faster tempo
music. One trying to top the other on how dark and deep and fast it sounded. The idea of playing
songs ideally talking about sensitive topic, war, violence, and even satanism was all thought about
when creating this type of music for it's what they thought was "Bad A––". Head banging culture
was the cause for thrash metal and soon the NWOBHM movement began inspiring new branches of
music. All branched off a unique style that came from NWOBHM whether it be its intimation sense,
