The Harvard-Radcliffe Orchestra (HRO) is a collegiate symphony orchestra comprised of Harvard students and based in Cambridge, Massachusetts. Founded in March of 1808 as the Pierian Sodality, the orchestra is considered by some to be the oldest symphony orchestra in the United States. This is disputed by others because of the organization's somewhat informal beginnings (the original charter states that the intent of the Pierian Sodality is to "perform music for the enjoyment of others as well as serenade young women in the square"), and as a result, some consider the New York Philharmonic to be the oldest American orchestra. The HRO assumed its current form as a modern symphony orchestra during the first half of the 20th century, and was, for a brief time, the nation's largest collegiate orchestra.
The orchestra currently contains over 100 members, and is the largest of the orchestras at Harvard University (though at one point during its history, the orchestra contained only one member, a flutist named Henry Gassett). In general, only students of Harvard College are eligible for membership, though this rule is not absolute and has occasionally been waived when necessary. The orchestra plays four concerts every year in Sanders Theater on Harvard's campus. Its alumni board is still known as the Pierian Sodality of 1808.
The orchestra has been led since 1964 by James Yannatos, a composer and member of the music faculty at Harvard.
The HRO has toured various places throughout its history, including Brazil, Washington, D.C., Mexico, Canada, Carnegie Hall, Italy, Soviet Union, Asia, and Europe. In 1978, the HRO placed third in the International Festival of Student Orchestras.

Integration is a core concept of advanced mathematics, specifically, in the fields of calculus and mathematical analysis. Given a function f(x) of a real variable x and an interval [a,b] of the real line, the integral
$int_a^b f(x),dx$
represents the area of a region in the xy-plane bounded by the graph of f, the x-axis, and the vertical lines x=a and x=b.
The term "integral" may also refer to the notion of antiderivative, a function F whose derivative is the given function f. In this case it is called an indefinite integral, while the integrals discussed in this article are termed definite integrals. Some authors maintain a distinction between antiderivatives and indefinite integrals.
The principles of integration were formulated by Isaac Newton and Gottfried Wilhelm Leibniz in the late seventeenth century. Through the fundamental theorem of calculus, that they independently developed, integration is connected with differentiation, and the definite integral of a function can be easily computed once an antiderivative is known. Integrals and derivatives became the basic tools of calculus, with numerous applications in science and engineering.
A rigorous mathematical definition of the integral was given by Bernhard Riemann. It is based on a limiting procedure which approximates the area of a curvilinear region by breaking the region into thin vertical slabs. Beginning in the nineteenth century, more sophisticated notions of integral began to appear, where the type of the function as well as the domain over which the integration is performed has been generalised. A line integral is defined for functions of two or three variables, and the interval of integration [a,b] is replaced by a certain curve connecting two points on the plane or in the space. In a surface integral, the curve is replaced by a piece of a surface in the three-dimensional space. Integrals of differential forms play a fundamental role in modern differential geometry. These generalizations of integral first arose from the needs of physics, and they play an important role in the formulation of many physical laws, notably those of electrodynamics. Modern concepts of integration are based on the abstract mathematical theory known as Lebesgue integration, developed by Henri Lebesgue.

History
Integration can be traced as far back as ancient Egypt, circa 1800 BC, with the Moscow Mathematical Papyrus demonstrating knowledge of a formula for the volume of a pyramidal frustum. The first documented systematic technique capable of determining integrals is the method of exhaustion of Eudoxus (circa 370 BC), which sought to find areas and volumes by breaking them up into an infinite number of shapes for which the area or volume was known. This method was further developed and employed by Archimedes and used to calculate areas for parabolas and an approximation to the area of a circle. Similar methods were independently developed in China around the 3rd Century AD by Liu Hui, who used it to find the area of the circle. This method was later used by Zu Chongzhi to find the volume of a sphere.
Significant advances on techniques such as the method of exhaustion did not begin to appear until the 16th Century AD. At this time the work of Cavalieri with his method of indivisibles, and work by Fermat, began to lay the foundations of modern calculus. Further steps were made in the early 17th Century by Barrow and Torricelli, who provided the first hints of a connection between integration and differentiation.

Pre-calculus integration
The major advance in integration came in the 17th Century with the independent discovery of the fundamental theorem of calculus by Newton and Leibniz. The theorem demonstrates a connection between integration and differentiation. This connection, combined with the comparative ease of differentiation, can be exploited to calculate integrals. In particular, the fundamental theorem of calculus allows one to solve a much broader class of problems. Equal in importance is the comprehensive mathematical framework that both Newton and Leibniz developed. Given the name infinitesimal calculus, it allowed for precise analysis of functions within continuous domains. This framework eventually became modern Calculus, whose notation for integrals is drawn directly from the work of Leibniz.

Newton and Leibniz
While Newton and Leibniz provided systematic approach to integration, their work lacked a degree of rigour. Bishop Berkeley memorably attacked infinitesimals as "the ghosts of departed quantity". Calculus acquired a firmer footing with the development of limits and was given a suitable foundation by Cauchy in the first half of the 19th century. Integration was first rigorously formalised, using limits, by Riemann. Although all piecewise continuous and bounded functions are Riemann integrable on a bounded interval, subsequently more general functions were considered, to which Riemann's definition does not apply, and Lebesgue formulated a different definition of integral, founded in measure theory. Other definitions of integral, extending Riemann's and Lebesgue's approaches, were proposed.

Formalising integrals
Isaac Newton used a small vertical bar above a variable to indicate integration, or placed the variable inside a box. The vertical bar was easily confused with $dot{x}$ or $x',!$, which Newton used to indicate differentiation, and the box notation was difficult for printers to reproduce, so these notations were not widely adopted.
The modern notation for the indefinite integral was introduced by Gottfried Leibniz in 1675 (Burton 1988, p. 359; Leibniz 1899, p. 154). He derived the integral symbol, "∫", from an elongated letter S, standing for summa (Latin for "sum" or "total"). The modern notation for the definite integral, with limits above and below the integral sign, was first used by Joseph Fourier in Mémoires of the French Academy around 1819–20, reprinted in his book of 1822 (Cajori 1929, pp. 249–250; Fourier 1822, §231). In Arabic mathematical notation which is written from right to left, an inverted integral symbol is used (W3C 2006).

Notation
If a function has an integral, it is said to be integrable. The function for which the integral is calculated is called the integrand. The region over which a function is being integrated is called the domain of integration. In general, the integrand may be a function of more than one variable, and the domain of integration may be an area, volume, a higher dimensional region, or even an abstract space that does not have a geometric structure in any usual sense.
The simplest case, the integral of a real-valued function f of one real variable x on the interval [a, b], is denoted by
$int_a^b f(x),dx .$
The ∫ sign, an elongated "S", represents integration; a and b are the lower limit and upper limit of integration, defining the domain of integration; f is the integrand, to be evaluated as x varies over the interval [a,b]; and dx can have different interpretations depending on the theory being used. For example, it can be seen as merely a notation indicating that x is the 'dummy variable' of integration, as a reflection of the weights in the Riemann sum, a measure (in Lebesgue integration and its extensions), an infinitesimal (in non-standard analysis) or as an independent mathematical quantity: a differential form. More complicated cases may vary the notation slightly.

Terminology and notation
Integrals appear in many practical situations. Consider a swimming pool. If it is rectangular, then from its length, width, and depth we can easily determine the volume of water it can contain (to fill it), the area of its surface (to cover it), and the length of its edge (to rope it). But if it is oval with a rounded bottom, all of these quantities call for integrals. Practical approximations may suffice at first, but eventually we demand exact and rigorous answers to such problems.
To start off, consider the curve y = f(x) between x = 0 and x = 1, with f(x) = √x. We ask:
What is the area under the function f, in the interval from 0 to 1?
and call this (yet unknown) area the integral of f. The notation for this integral will be
$int_0^1 sqrt x , dx ,!$.
As a first approximation, look at the unit square given by the sides x=0 to x=1 and y=f(0)=0 and y=f(1)=1. Its area is exactly 1. As it is, the true value of the integral must be somewhat less. Decreasing the width of the approximation rectangles shall give a better result; so cross the interval in five steps, using the approximation points 0, )/(q+1).)
Historically, after the failure of early efforts to rigorously define infinitesimals, Riemann formally defined integrals as a limit of ordinary weighted sums, so that the dx suggested the limit of a difference (namely, the interval width). Shortcomings of Riemann's dependence on intervals and continuity motivated newer definitions, especially the Lebesgue integral, which is founded on an ability to extend the idea of "measure" in much more flexible ways. Thus the notation
$int_A f(x) , dmu ,!$
refers to a weighted sum in which the function values are partitioned, with μ measuring the weight to be assigned to each value. (Here A denotes the region of integration.) Differential geometry, with its "calculus on manifolds", gives the familiar notation yet another interpretation. Now f(x) and dx become a differential form, ω = f(x)dx, a new differential operator d, known as the exterior derivative appears, and the fundamental theorem becomes the more general Stokes' theorem,
$int_{A} bold{d} omega = int_{part A} omega , ,!$
from which Green's Theorem, the divergence theorem, and the fundamental theorem of calculus follow.
More recently, infinitesimals have reappeared with rigor, through modern innovations such as non-standard analysis. Not only do these methods vindicate the intuitions of the pioneers, they also lead to new mathematics.
Although there are differences between these conceptions of integral, there is considerable overlap. Thus the area of the surface of the oval swimming pool can be handled as a geometric ellipse, as a sum of infinitesimals, as a Riemann integral, as a Lebesgue integral, or as a manifold with a differential form. The calculated result will be the same for all.

Introduction
There are many ways of formally defining an integral, not all of which are equivalent. The differences exist mostly to deal with differing special cases which may not be integrable under other definitions, but also occasionally for pedagogical reasons. The most commonly used definitions of integral are Riemann integrals and Lebesgue integrals.

Formal definitions

Main article: Riemann integral Riemann integral

Main article: Lebesgue integral Lebesgue integral
Although the Riemann and Lebesgue integrals are the most important definitions of the integral, a number of others exist, including:

The Riemann-Stieltjes integral, an extension of the Riemann integral.
The Lebesgue-Stieltjes integral, further developed by Johann Radon, which generalizes the Riemann-Stieltjes and Lebesgue integrals.
The Daniell integral, which subsumes the Lebesgue integral and Lebesgue-Stieltjes integral without the dependence on measures.
The Henstock-Kurzweil integral, variously defined by Arnaud Denjoy, Oskar Perron, and (most elegantly, as the gauge integral) Jaroslav Kurzweil, and developed by Ralph Henstock. Other integrals

Linearity
A number of general inequalities hold for Riemann-integrable functions defined on a closed and bounded interval [a, b] and can be generalized to other notions of integral (Lebesgue and Daniell).

$m(b - a) leq int_a^b f(x) , dx leq M(b - a).$

$int_a^b f(x) , dx leq int_a^b g(x) , dx.$
This is a generalization of the above inequalities, as M(ba) is the integral of the constant function with value M over [a, b].

$int_c^d f(x) , dx leq int_a^b f(x) , dx.$

$
(fg)(x)= f(x) g(x), ; f^2 (x) = (f(x))^2, ; |f| (x) = |f(x)|.,$

If f is Riemann-integrable on [a, b] then the same is true for |f|, and

$left| int_a^b f(x) , dx right| leq int_a^b | f(x) | , dx.$
Moreover, if f and g are both Riemann-integrable then f are also Riemann integrable and the following Minkowski inequality holds: Inequalities for integrals
In this section f is a real-valued Riemann-integrable function. The integral
$int_a^b f(x) , dx$
over an interval [a, b] is defined if a < b. This means that the upper and lower sums of the function f are evaluated on a partition a = x0x1 ≤ . . . ≤ xn = b whose values xi are increasing. Geometrically, this signifies that integration takes place "left to right", evaluating f within intervals [xi , xi +1] where an interval with a higher index lies to the right of one with a lower index. The values a and b, the end-points of the interval, are called the limits of integration of f. Integrals can also be defined if a > b:

$int_a^b f(x) , dx = - int_b^a f(x) , dx.$
This, with a = b, implies:

$int_a^a f(x) , dx = 0.$
The first convention is necessary in consideration of taking integrals over subintervals of [a, b]; the second says that an integral taken over a degenerate interval, or a point, should be zero. One reason for the first convention is that the integrability of f on an interval [a, b] implies that f is integrable on any subinterval [c, d], but in particular integrals have the property that:

$int_a^b f(x) , dx = int_a^c f(x) , dx + int_c^b f(x) , dx.$
With the first convention the resulting relation
begin{align}
int_a^c f(x) , dx &{}= int_a^b f(x) , dx - int_c^b f(x) , dx
&{} = int_a^b f(x) , dx + int_b^c f(x) , dx
end{align}

is then well-defined for any cyclic permutation of a, b, and c.
Instead of viewing the above as conventions, one can also adopt the point of view that integration is performed on oriented manifolds only. If M is such an oriented m-dimensional manifold, and M' is the same manifold with opposed orientation and ω is an m-form, then one has (see below for integration of differential forms):
$int_M omega = - int_{M'} omega ,.$

$F(x) = int_a^x f(t), dt.$
then F is continuous on [a, b]. If f is continuous at x in [a, b], then F is differentiable at x, and F ′(x) = f(x).

$int_a^b f(t), dt = F(b) - F(a).$

$F(x) = int_a^x f(t) , dt$
is an anti-derivative of f on [a, b]. Moreover,

Methods and applications
The most basic technique for computing integrals of one real variable is based on the fundamental theorem of calculus. It proceeds like this:
$int_a^b f(x),dx = F(b)-F(a).$
Note that the integral is not actually the antiderivative, but the fundamental theorem allows us to use antiderivatives to evaluate definite integrals.
The difficult step is often finding an antiderivative of f. It is rarely possible to glance at a function and write down its antiderivative. More often, it is necessary to use one of the many techniques that have been developed to evaluate integrals. Most of these techniques rewrite one integral as a different one which is hopefully more tractable. Techniques include:
Even if these techniques fail, it may still be possible to evaluate a given integral. The next most common technique is residue calculus, whilst for nonelementary integrals Taylor series can sometimes be used to find the antiderivative. There are also many less common ways of calculating definite integrals; for instance, Parseval's identity can be used to transform an integral over a rectangular region into an infinite sum. Occasionally, an integral can be evaluated by a trick; for an example of this, see Gaussian integral.
Computations of volumes of solids of revolution can usually be done with disk integration or shell integration.
Specific results which have been worked out by various techniques are collected in the list of integrals.

Choose a function f(x) and an interval [a, b].
Find an antiderivative of f, that is, a function F such that F' = f.
By the fundamental theorem of calculus, provided the integrand and integral have no singularities on the path of integration,

$int_a^b f(x),dx = F(b)-F(a).$

Therefore the value of the integral is F(b) − F(a).

Growth capital is a very flexible type of financing. The money borrowed under a growth capital line of credit can be used for any corporate purposes. There are no requirements to provide invoices or other backup material when borrowing under this type of facility, so administration is simplified as well.
Growth capital can be a beneficial way to extend a company's runway between rounds of financing. The extra time can be used to complete additional milestones that will raise the company's valuation, or as insurance to ensure that all intended milestones are successfully accomplished.

The Court system of Canada is made up of many courts differing in levels of legal superiority and separated by jurisdiction. Some of the courts are federal in nature while others are provincial or territorial.
The Canadian constitution gives the federal government the exclusive right to legislate criminal law while the provinces have exclusive control over civil law. The provinces have jurisdiction over the administration of justice in their territory. Almost all cases, whether criminal or civil, start in provincial courts and may be eventually appealed to higher level courts. The quite small system of federal courts only hear cases concerned with matters which are under exclusive federal control, such as immigration. The federal government appoints and pays for both the judges of the federal courts and the judges of the superior-level court of each province. The provincial governments are responsible for appointing judges of the lower provincial ("inferior-level") courts.
This intricate interweaving of federal and provincial powers is typical of the Canadian constitution.

Outline of the Court system
Although created by an Act of the Parliament of Canada in 1875, its decisions could be reviewed by the Judicial Committee of the Privy Council until 1949 when the Supreme Court of Canada truly became the final and highest court in the country. The court currently consists of nine justices, which include the Chief Justice of Canada, and its duties include hearing appeals of decisions from the appellate courts (to be discussed next) and, on occasion, delivering references (i.e., the court's opinion) on constitutional questions raised by the federal government. By law, three of the nine justices are appointed from Quebec; because of Quebec's use of civil law.

These courts of appeal (as listed below by province and territory in alphabetical order) exist at the provincial and territorial levels and were separately constituted in the early decades of the 20th century, replacing the former Full Courts of the old Supreme Courts of the provinces, many of which were then re-named Courts of Queens Bench. Their function is to review decisions rendered by the superior-level courts and to do references (i.e., deliver a judicial opinion) when requested by a provincial or territorial government. These appellate courts do not normally conduct trials and hear witnesses.
These courts are Canada's equivalent of the Court of Appeal in England and the various State Supreme Courts and US Courts of Appeals in the United States. Each of the above-listed appellate courts is the highest court from its respective province or territory. A province's chief justice (i.e., highest ranking judge) sits in the appellate court of that province.

Alberta Court of Appeal
British Columbia Court of Appeal
Manitoba Court of Appeal
New Brunswick Court of Appeal
Supreme Court of Newfoundland (Court of Appeal)
Court of Appeal for the Northwest Territories
Nova Scotia Court of Appeal
Nunavut Court of Appeal
Ontario Court of Appeal
Supreme Court of Prince Edward Island - Appeal Division
Quebec Court of Appeal
Court of Appeal of the Yukon Territory Appellate courts of the provinces and territories
These courts (as listed below by province and territory in alphabetical order) exist at the provincial and territorial levels. The superior courts are the courts of first instance for divorce petitions, civil lawsuits involving claims greater than small claims, and criminal prosecutions for "indictable offences" (i.e., "felonies" in American legal terminology). They also perform a reviewing function for judgements from the local "inferior" courts and administrative decisions by provincial or territorial government entities such as labour boards, human rights tribunals and licensing authorities.
Furthermore, some of these superior courts (like the one in Ontario) have specialized branches that deal only with certain matters such as family law or small claims. To complicate things further, the Ontario Superior Court of Justice has a branch called the Divisional Court that hears only appeals and judicial reviews of administrative tribunals and whose decisions have greater binding authority than those from the "regular" branch of the Ontario Superior Court of Justice. Although a court, like the Supreme Court of British Columbia, may have the word "supreme" in its name, it is not necessarily the highest court from its respective province or territory.

Court of Queen's Bench for Saskatchewan

Main article: Provincial Court Provincial and territorial ("inferior") courts
The Federal Court and the more specialized Tax Court of Canada exists primarily to review administrative decisions by federal government bodies such as the immigration board and hear lawsuits under the federal government's jurisdiction such as intellectual property and maritime law.
The Federal Court of Appeal hears appeals from decisions rendered by the Federal Court, the Tax Court of Canada and a certain group of federal administrative tribunals like the National Energy Board and the federal labour board. All judges of the Federal Court are ex officio judges of the Federal Court of Appeal, and vice versa, although it is rare that a judge of one court will sit as a member of the other.
Before 2003, the Federal Court was known as the Federal Court of Canada - Trial Division while the Federal Court of Appeal was known as the Federal Court of Canada - Appeal Division. In turn, the Federal Court of Canada is descended from the old Exchequer Court of Canada created back in 1875.
Although the federal type courts can be said to have the same prestige as the superior courts from the provinces and territories, the federal ones lack the "inherent jurisdiction" (to be explained later) possessed by superior courts such as the Ontario Superior Court of Justice.

The "courts martial" are conducted and presided over by military personnel and exist for the prosecution of military personnel, as well as civilian personnel who accompany military personnel, accused of violating the Code of Service Discipline, which is found in the National Defence Act (R.S.C. 1985, Chapter N-5) and constitutes a complete code of military law applicable to persons under military jurisdiction.
The decisions of the courts martial can be appealed to the Court Martial Appeal Court of Canada which, in contrast, exists outside the military and is made up of civilian judges. This appellate court is the successor of the Court Martial Appeal Board which was created in 1950, presided over by civilian judges and lawyers, and was the first ever civilian-based adjudicating body with authority to review decisions by a military court. The Court Martial Appeal Court is made up of civilian judges from the Federal Court, Federal Court of Appeal, and the superiour courts of the provinces. The current Chief Justice of the Court Martial Appeal Court (as of September 17, 2004) is Edmond P. Blanchard.

Special General Court Martial Courts of military law
Known in Canada as simply "tribunals", these are non-judicial adjudicative bodies, which means that they adjudicate (hear evidence and render decisions) like the courts do BUT are not presided over by judges. Instead, the adjudicators may be experts of the very specific legal field handled by the tribunal (e.g., labour law, human rights law, immigration law, energy law, liquor licensing law, etc.) who hear arguments and evidence provided by lawyers before making a written decision on record. Its decisions can be reviewed by a court through an appeal or a process called "judicial review". The reviewing court may be required to show some deference to the tribunal if the tribunal possesses some highly specialized expertise or knowledge that the court does not have. The degree of deference will also depend on such factors as the specific wording of the legislation creating the tribunal.
Tribunals may take into consideration the Canadian Charter of Rights and Freedoms, which is part of Canada's constitution. The extent to which tribunals may use the Charter in their decisions is a source of ongoing legal debate.
Appearing before some administrative tribunals may feel like appearing in a court, but the tribunal's procedure is relatively less formal than that of the court, and more importantly, the rules of evidence are not as strictly observed. In other words, some evidence that would be inadmissible in a court hearing could be allowed in a tribunal hearing. The presiding adjudicator is normally called "Mister/Madam Chair", and lawyers routinely appear in tribunals advocating a matter for their clients. A person does not require a lawyer to appear before an administrative tribunal. Indeed, many of these tribunals are specifically designed to be less formal than courts. Furthermore, some of these tribunals are part of a comprehensive dispute-resolution system, which may emphasize mediation rather than litigation. For example, provincial human rights commissions routinely use mediation to resolve many human rights complaints without the need for a hearing.
What tribunals all have in common is that they are created by statute, their adjudicators are appointed by government, and they focus on very particular and specialized areas of law. Because some subject matters (e.g., immigration) fall within federal jurisdiction while others (e.g., liquor licensing) in provincial jurisdiction, some tribunals are created by federal law while others are created by provincial law. Yet, there are both federal and provincial tribunals for some subject matters such as unionized labour and "human rights" (in American legal parlance, the "civil rights" of marginalized or/and disadvantaged social groups such as women, racial minorities, the disabled, homosexuals, certain religious groups, etc.).
Most importantly, from a lawyer's perspective, is the fact that the principle of stare decisis does not apply to tribunals. In other words, a tribunal adjudicative could legally make a decision that differs from a past decision, on the same subject and issues, delivered by the highest court in the land. Because a tribunal is not bound by legal precedent, established by itself or by a reviewing court, A tribunal is not court even though it performs an important adjudicative function and contributes to the development of law like a court would do. Although stare decisis does not apply to tribunals, their adjudicators will nonetheless find a prior court decision on a similar subject to be highly persuasive and will likely follow the courts in order to ensure consistency in the law and to prevent the embarrassment of having their decisions overturned by the courts.
Among the federal tribunals, there is a small group of tribunals whose decisions must be appealed directly to the Federal Court of Appeal rather than to the Federal Court Trial Division. These so-called "super tribunals" are listed in Subsection 28(1) of the Federal Court Act (R.S.C. 1985, Chapter F-7) and some examples include the National Energy Board, Canadian International Trade Tribunal, the Competition Tribunal, the Canada Industrial Relations Board (i.e. federal labour board), the Copyright Board, and the Canadian Radio-television and Telecommunications Commission ("CRTC").

These are the superior courts from the provinces and territories as discussed above. The words "inherent jurisdiction" refers to the fact that the jurisdiction of the superior courts is more than just what is conferred by statute. Following the principles of English common law, because the superior courts derive their authority from the Constitution, they can hear any matter unless there is a federal or provincial statute that says otherwise or that gives exclusive jurisdiction to some other court or tribunal. The doctrine of "inherent jurisdiction" gives superior courts greater freedom than statutory courts (to be explained next) to be flexible and creative in the delivering of legal remedies and relief.

Courts of inherent jurisdiction
These courts include the Supreme Court of Canada, the different types of federal courts, the various appellate courts from the provinces and territories, and the numerous low level "provincial" courts. Their decision-making power is granted by either the federal parliament or a provincial legislature.
The word "statutory" refers to the fact that these courts' powers are derived from a type of legislation called a statute and is defined and limited by a statute. A statutory court cannot try cases in areas of law that are not mentioned or suggested in the statute. In this sense, statutory courts are similar to non-judicial adjudicative bodies such as administrative tribunals, boards, commissions, etc. which are created and given limited power by legislation. The practical implication of this is that a statutory court cannot provide a type of legal remedy or relief that is not expressly or implicitly referred to in its enabling or empowering statute.

In Hinduism, Durga (Sanskrit: "the inaccessible"
Durga is depicted as a warrior woman riding a lion or a tiger with multiple hands carrying weapons and assuming mudras, or symbolic hand gestures. This form of the Goddess is the embodiment of feminine and creative energy (Shakti).

The 4 day Durga Puja is the biggest annual festival in Bengal and other parts of Eastern India, but it is celebrated in various forms throughout the Hindu universe.
The day of Durga's victory is celebrated as Vijaya Dashami (East and South India), Dashain (Nepal) or Dussehra (North India) - these words literally mean "the tenth" (day), vijaya means "of-victory". In Kashmir she is worshipped as shaarika (the main temple is in Hari Parbat in Srinagar).
The actual period of the worship however may be on the preceding nine days followed by the last day called Vijayadashami in North India or five days in Bengal, (from the sixth to tenth day of the waxing-moon fortnight). Nine aspects of Durga known as Navadurga are meditated upon, one by one during the nine-day festival by devout shakti worshippers.
In North India, this tenth day, signifying Rama's victory in his battle against the demon Ravana, is celebrated as Dussehra - gigantic straw effigies of Ravana are burnt in designated open spaces (e.g. Delhi's Ram Lila grounds), watched by thousands of families and little children.
In Gujarat it is celebrated as the last day of Navaratri, during which the Garba dance is performed to celebrate the vigorous victory of Mahishasura-mardini Durga.
The Goddess Durga worshipped in her peaceful form as Shree Shantadurga also known as santeri , is the patron Goddess of Goa. She is worshipped by all Goan Hindus irrespective of caste and even by some Christians in Goa.
Goddess Durga is worshipped in many temples of Dakshina Kannada district of Karnataka.

Montevideo (IPA: [monteβi'deo]) is the largest city, capital and chief port of Uruguay. Montevideo is the primate city in Uruguay, the only city in country with a population over 100,000. Montevideo has a privileged harbour, one of the most important in the Americas. Also, it has beautiful beaches, like Pocitos, Buceo, Malvin, Playa de los Ingleses, Playa Verde, Punta Gorda and Carrasco. Many monuments and museums cover the city, as well as historic buildings and squares. The city's mayor is Ricardo Ehrlich. According to the Mercer Human Resource Consulting, Montevideo is the Latin American city with the highest quality of life (followed by Buenos Aires and Santiago de Chile).

Population
Montevideo is situated in the south of the country, The geographic coordinates are 34.5° S, 56°W.
18 de Julio is the city's main avenue and extends from the Plaza Independencia, which is the junction between the Ciudad Vieja (the historical quarter) and the rest of the city, to the neighbourhood of Cordón.

Geography

History
There are at least two explanations for the name Montevideo: The first states that it comes from the Portuguese "Monte vide eu" which means "I see a mountain". The second is that the Spaniards recorded the location of a mountain in a map as "Monte VI De Este a Oeste" meaning "The sixth mountain from east to west". The city's full original name is San Felipe y Santiago de Montevideo.

Origin of Name
Montevideo was first found by Juan Diaz De Solis. He arrived in 1516. He encountered the natives living there, and was killed by them, along with the rest of his group of travelers. The Portuguese founded Colonia del Sacramento in the 17th century despite Spanish claims to the area due to the Treaty of Tordesillas. The Spanish chased the Portuguese out of a fort in the area in 1724. Then, Bruno Mauricio de Zabalagovernor of Buenos Aires – founded the city on December 24, 1726 to prevent further incursions.
In 1828, the town became the capital of Uruguay.
The city fell under heavy British influence from the early 19th century until the early 20th century as a way to circumvent Argentine and Brazilian commercial control. It was repeatedly besieged by Argentinean dictator Juan Manuel de Rosas between 1838 and 1851. Between 1860 and 1911, British Owned Railway companies built an extensive railroad network linking the city to the surrounding countryside.

Early History
During World War II, a famous incident involving the German pocket battleship Admiral Graf Spee took place in Punta del Este, 200 km from Montevideo. After the Battle of the River Plate with the British navy on December 13, 1939, the Graf Spee retreated to Montevideo's port, which was considered neutral then. To avoid risking the crew in what he thought would be a losing battle, Captain Hans Langsdorff scuttled the ship on December 17. Langsdorff committed suicide two days later. On 10 February 2006, the eagle figurehead of the Admiral Graf Spee was recovered. To protect the feelings of those still sensitive to Nazi Germany, the swastika on the figurehead was covered as it was pulled from the water.
Since 2005 the Mayor of Montevideo (styled Intendente Municipal in Spanish) has been Ricardo Ehrlich, of the Frente Amplio (Broad Front), gaining 61% of the vote in the Mayoral elections, beating Pedro Bordaberry of the Partido Colorado, who scored 27%.

20th Century
Montevideo began as a minor settlement. In 1860, Montevideo had a population of 37,787. By 1884, the population had grown to 104,472, including many immigrants.
During the mid-20th century, military dictatorship and economic stagnation caused a decline whose residual effects are still seen today. Many rural poor flooded the city, with a large concentration in Ciudad Vieja.
Recently, economic recovery and stronger trade ties with Uruguay's neighbours have led to renewed agricultural development and hopes for greater future prosperity.
As of 2004, the city has a population of 1.35 million out of a total of 3.43 million in the country as a whole.[1] The greater metropolitan area has 1.8 million people.
Montevideo is served by Carrasco International Airport.

Growth/economy
The city shows some evidence of world city formation. The past lives on in style, though. Back in 1870, the average living standards were similar to those in the United States.

Montevideo hosted all the matches of the 1 FIFA World Cup in 1930. Uruguay won the tournament by defeating Argentina 4-2, and later in 1950 defeated heavy favored hosts Brazil 2-1, achieving its second World Cup Championship. Uruguay also won several olympic medals in soccer including 2 gold medals, and has won the most "Copa America" tournaments, the world's second most prestigious tournament after the World Cup (tied with Argentina at 14 wins). Its Estadio Centenario is considered a temple of world football. The city is home to two of the most important South American football clubs: Nacional and Peñarol. Consistently since its early successes, Uruguayan footballers have been among the worlds best, recently producing such soccer greats as Diego Forlan, Paulo Montero and Alvaro Recoba, and currently boasts the highest number of world class exports to the European leagues out of any country in South America including fellow soccer powerhouses Argentina and Brazil, a surprising feat when considering the population of just over 3 million is a small fraction of most other South American countries.
There is strong world-wide sentiment that the centennial anniversary Fifa World Cup tournament to be held in 2030, be played at least in part in Uruguay, namely in the Centenario Stadium which was built specifically as the innagurational stadium for the tournament of 1930, and fittingly translates to "The Centennial Stadium".

Wenzhou (Simplified Chinese: 温州; Traditional Chinese: 溫州; pinyin: Wēnzhōu) is a prefecture-level city (or provincial subregion) in southeastern Zhejiang province, People's Republic of China. It has a population of 7,777,000 in 2006, with 1,336,000 residents in the 3 districts (区) of the city with the same name. It also contains 2 more cities and 6 counties. It borders Lishui to the west, Taizhou to the north, and looks out to the East China Sea to the east.
Wenzhou was a prosperous foreign treaty port, which remains well-preserved today. It is also known for its emigrants who leave their native land for Europe and the United States, with a reputation for being enterprising folk who start restaurants, retail and wholesale businesses in their adopted countries.

Wenzhou, also known as Yongjia (or Yung-chia) has a history which goes back to about 2000 BC, when it became known for its pottery production. In the 2nd century BC it was called the Kingdom of Dong'ou. Under the Tang Dynasty, it was promoted to prefecture status and given its current name in 675 AD.
Throughout its history, Wenzhou's traditional economic role has been as a port giving access to the mountainous interior of southern Zhejiang Province. In 1876 Wenzhou was opened to the foreign tea trade, but no foreign settlement was ever made there. In 19371942 during the war with Japan, Wenzhou became an important port due to its being one of the few Chinese ports still under Chinese control. It declined in the later years of the war but began to recover after coastal trade along the Zhejiang coast was re-established in 1955.
Wenzhou derives its present name from its mild climate. With jurisdiction over three districts, two county-level cities and six counties, Wenzhou covers a land area of 11,784 square kilometers and sea area of 11,000 square kilometers. The population of the prefectural level city is 7.7 million including 2 million urban residents, divided among 2 "county level" cities and 3 wards.
As a coastal city, Wenzhou is rich in natural resources. The 339-kilometer long coastline gives the city abundant marine resources and many beautiful islands. Dongtou, one of the counties in Wenzhou, is also called the "County of one hundred islands". Wenzhou also boasts wonderful landscapes with rugged mountains and tranquil waters, including three state-level scenic spots, namely the Yandang Mountain, the Nanxi River and the Baizhangji Fall-Feiyun Lake, and two national nature reserves, namely the Wuyanling Ridge and the Nanji Islands, among which Yandang Mountain has been named as World Geopark, while Nanji Islands listed as UNESCO's Marine Nature Reserve of World Biosphere Reserves. Scenic area accounts for 25% of the city's land space, which is a perfect integration of exotic mountains, tender water and charming sea.

History
Wenzhou exports food, tea, wine, jute, timber, paper, Alunite (a non-metallic mineral used to make alum and fertilizer). Alunite is quite abundant here and sometimes Wenzhou claims to be the "Alunite Capital of the World". Its main industries are food processing, papermaking, and building materials, with some engineering works producing mostly farm machinery. From the 1990s, low-voltage electric appliances manufacturing became a major industry in Wenzhou, with some of the large private enterprises setting up joint ventures with GE and Schneider. Since 1994, exploration for oil and natural gas has commenced in the East China Sea 100 km off the coast of Wenzhou. Companies such as Texaco, Chevron, Shell and Japex have started to drill for oil but the operations have been largely unsuccessful.
Since the new government term started in 2004, the local government has initiated a brand-new development strategy of inviting investment from international market, which is dubbed as "Number 1 Project" of the city. It is a particularly bold endeavour for Wenzhou, especially with the backdrop of declining FDI in the national level.
Wenzhou is a city full of vitality, with creativity as the source of its vitality. Since China adopted the opening up and reform policy, Wenzhou has been the first to set up individual and private enterprises as well as shareholding cooperative economy in China. It has also taken the lead in carrying out the financial system reform and the structural reform in townships. Being a pioneer in utilizing marketing mechanism to develop urban constructions, Wenzhou has won a number of firsts in China and set many national records.
Vitality comes from Wenzhou natives. Without much dependence in state investments, the development of the city really lies on the efforts of the natives. Vitality results from business culture, which is the top feature of Wenzhou's economy. Wenzhou businessmen have set their feet on the way of accumulating capital and also made themselves one of the important forces of the overseas Chinese businessmen. "Big market with small commodities, small money with high capital intensity" has become the prominent character of Wenzhou's economy. Vitality also originates from opening up of market. In recent years, Wenzhou has continuously deregulated to embrace foreign investment and opened more widely to the outside world, encouraging the aspiring spirit of the local people to start-up businesses. With enduring vitality and sustained innovation, the economy of Wenzhou has always enjoyed healthy development. From 1978 through 2005, the GDP of the city has increased from 1.32 billion RMB to 160 billion RMB with the gross fiscal revenue increasing from 0.135 billion RMB to 20.49 billion RMB, and the net per capita income for rural residents increasing from 113.5 RMB to 6,845 RMB. What's more, the per capita disposable income for urban residents increased from 422.6 RMB in 1981 to 19,805 RMB in 2005.
Wenzhou is the birthplace of the China private economy. In the early days of opening up and reform, the people of Wenzhou took the lead in developing commodity economy, household industries and specialized markets. Thousands upon thousands of people and families were engaged in household manufacturing to develop individual and private economy. Up till now, Wenzhou has a total of 240,000 individually-owned commercial and industrial units and 130,000 private enterprises of which 180 are group companies, 4 among China's top 500 enterprises and 36 among national 500 top private enterprises. The quantity, industrial output, tax, export and number of employees of the private enterprises account for 99%, 96%, 75%, 95% and 80% of the whole city respectively. There are 27 national production bases such as "China's Shoes Capital" and "China's Capital of Electrical Equipment", 40 China's famous trademarks and China's famous-brand products and 67 national inspection-exempt products in the city. The development of private economy in Wenzhou has created the "Wenzhou Economic Model", which gives great inspiration to the modernization drive in China.

Habitat destruction is a process of land use change in which one habitat-type is removed and replaced with another habitat-type. In the process of land-use change, plants and animals which previously used the site are displaced or destroyed, reducing biodiversity. Urban Sprawl is one cause of habitat destruction. Other important causes of habitat destruction include mining, trawling, and agriculture. Habitat destruction is currently ranked as the most important cause of species extinction worldwide.
