The Pantanal tour



The Pantanal is a tropical wetland and the world's largest wetland of any kind. It lies mostly within the Brazilian state of Mato Grosso do Sul but extends into Mato Grosso as well as into portions of Bolivia and Paraguay, sprawling over an area estimated at between 140,000 square kilometers (54,000 sq mi) and 195,000 square kilometers (75,000 sq mi). Various sub-regional ecosystems exist, each with distinct hydrologicalgeological and ecological characteristics; up to twelve of them have been defined (RADAMBRASIL 1982).[1][2][3][4][5]

80% of the Pantanal floodplains are submerged during the rainy seasons, nurturing an astonishing biologically diverse collection of aquatic plants and helping support a dense array ofanimal species. Though the Pantanal inevitably cuts a lower profile than the Amazon Rainforestto its north, its ecosystems are similarly precious.

The name "Pantanal" comes from the Portuguese word pântano, meaning wetlandbogswampor marsh. By comparison, the Brazilian highlands are locally referred to as the planaltoplateauor, literally, high plain.

Niagra falls


Power

The enormous energy of Niagara Falls has long been recognized as a potential source of power. The first known effort to harness the waters was in 1759, when Daniel Joncaire built a small canal above the Falls to power his sawmill. Augustus and Peter Porter purchased this area and all of American Falls in 1805 from the New York state government, and enlarged the original canal to provide hydraulic power for their gristmill and tannery. In 1853, the Niagara Falls Hydraulic Power and Mining Company was chartered, which eventually constructed the canals which would be used to generate electricity. In 1881, under the leadership of Jacob Schoellkopf, Niagara River's first hydroelectric generating station was built. The water fell 86 feet (26 m) and generated direct current electricity, which ran the machinery of local mills and lit up some of the village streets.


The Niagara Falls Power Company, a descendant of Schoellkopf's firm, formed the Cataract Company headed by Edward Dean Adams,[11] with the intent of expanding Niagara Falls power capacity. In 1890, a five-member International Niagara Commission headed by Sir William Thomson among other distinguished scientists deliberated on the expansion of Niagara hydroelectric capacity based on seventeen proposals, but could not select any as the best combined project for hydraulic development and distribution. When Nikola Tesla, for whom a memorial was later built at Niagara Falls, NY (USA), invented the three-phasesystem of alternating current power transmission, distant transfer of electricity became possible, as Westinghouse and Tesla had built the AC-power Ames Hydroelectric Generating Plant and proved it effective. In 1893, Westinghouse Electric was hired to design a system to generate alternating current on Niagara Falls, and three years after that, the world's first large AC power system was created, activated on August 26, 1895. The Adams Power Plant Transformer House remains as a landmark of the original system.

By 1896, with financing from moguls like J.P. MorganJohn Jacob Astor IV, and theVanderbilts, they had constructed giant underground conduits leading to turbines generating upwards of 100,000 horsepower (75 MW), and were sending power as far as Buffalo, 20 miles (32 km) away. Some of the original designs for the power transmission plants were created by the Swiss firm Faesch & Piccard, which also constructed the original 5,000HP waterwheels.

Private companies on the Canadian side also began to harness the energy of the Falls. The Government of the province of Ontario, Canada eventually brought power transmission operations under public control in 1906, distributing Niagara's energy to various parts of the Canadian province.

Other hydropower plants were also being built along the Niagara River. But in 1956, disaster struck when the region's largest hydropower station was partially destroyed in a landslide. The landslide drastically reduced power production and tens of thousands of manufacturing jobs were at stake. In 1957, Congress passed the Niagara Redevelopment Act, which granted the New York Power Authority the right to fully develop the United States' share of the Niagara River's hydroelectric potential.[12]

In 1961, when the Niagara Falls hydroelectric project first went on line, it was the largest hydropower facility in the Western world. Today, Niagara is still the largest electricity producer in New York State, with a generating capacity of 2.4 gigawatts (million kilowatts). Up to 375,000 US gallons (1,420 m3) of water a second is diverted from the Niagara River through conduits under the City of Niagara Falls to theLewiston and Robert Moses power plants. Currently between 50% and 75% of the Niagara River's flow is diverted via four huge tunnels that arise far upstream from the waterfalls. The water then passes through hydroelectric turbines that supply power to nearby areas of the Canada and the USA before returning to the river well past the Falls.[13] This water spins turbines that power generators, converting mechanical energy intoelectrical energy. When electricity demand is low, the Lewiston units can operate as pumps, to transporting water from the lower bay back up to the plant's reservoir allowing this water to be used again during the daytime, when electricity use peaks. During peak electrical demand, the same Lewiston pumps are reversed and actually become generators, similar to those at the Moses plant.[12]

During tourist season, water usage by the power plant is limited by a treaty signed by the U.S. and Canada in 1950 in order to preserve this natural attraction. On average the Niagara river contains 1,500,000 US gallons (5,700 m3) of water per second, half of which must flow over the falls during daylight hours from April through October. During other times the power plant may use up to three fourths of the total available water. During winter the Power Authority of New York works with Ontario Power Generation, to prevent ice on the Niagara River from interfering with power production and causing the flooding of shoreline property. One of their joint efforts is an 8,800-foot (2,700 m)–long ice boom, which prevents the buildup of ice, yet allows water to continue flowing downstream.[12]

The most powerful hydroelectric stations on the Niagara River are Sir Adam Beck 1 and 2 on the Canadian side, and the Robert Moses Niagara Power Plant and the Lewiston Pump Generating Plant on the American side. All together, Niagara's generating stations can produce about 4.4GW of power.

In August 2005 Ontario Power Generation, which is responsible for the Sir Adam Beck stations, announced plans to build a new 6.5 miles (10.5 km) tunnel to tap water from farther up the Niagara river than is possible with the existing arrangement. The project is expected to be completed in 2009, and will increase Sir Adam Beck's output by about 182 MW (4.2%).

Australia medical tour



When there is a significant price difference between countries for a given medical procedure, particularly in Southeast AsiaIndiaEastern Europe and where there are different regulatory regimes, in relation to particular medical procedures (e.g. dentistry), traveling to take advantage of the price or regulatory differences is often referred to as "medical tourism".

France university teacher in hall


Right after graduating from High School with a scientific background (Baccalaureat S), any student can register at a university of medicine (there are about 30 of them throughout the country). At the end of first year, an internal ranking examination takes place in each of these universities in order to implement the numerus clausus. First year consists mainly of theoretical classes such as biophysics and biochemistry,anatomyethics or histology. Passing first year is commonly considered as challenging and requires hard and continuous work. Each student can only try twice. For example, the Université René Descartes welcomes about 2000 students in first year and only 300 after numerus clausus.

The second and third year are usually mainly quite theoretical although the teachings are often accompanied by placements in the field (e.g. internships as nurses or in the emergency room, depending on the university).

During 4th, 5th and 6th years, medical students get a special status called 'Externe'. They work as interns every morning at the hospital plus a few night shifts a month and study in the afternoon. Each internship lasts between 3 and 4 month and takes place in a different department. Med students get 5 weeks off a year.

At the end of 6th year, they need to pass a national ranking exam which will determine their specialty. Indeed, the first student gets to choose first, then the second et caetera. Usually students work pretty hard during 5th and 6th years in order to train properly for the national ranking exam. During these years, actual practice at the hospital and some theoretical courses are meant to balance the training. Such interns' average wage stands between 100 and 300 euros a month (which is far from being enough to make a living).

After that ranking exams, students can start as residents in the specialty they have been able to pick. That is the point from which they also start getting paid (decently).

eGYPTY medical school teacher


In Egypt, medical school is a faculty of a university. Medical education lasts for 6 years, at the end of which the student is granted a MB BCh(بكالريوس الطب و الجراحة). After graduating there is a mandatory 12 month full time internship at one of the University or Government Teaching hospitals after which medical licensure as a General Practitioner (GP) is obtained. After that, the doctor has to register with the Ministry of Health & Population, and the Egyptian Medical Syndicate (نقابة الأطباء). The first 3 years of medical school cover the basic medical sciences, while the last 3 years are focused on clinical sciences.

Admission depends on the score of the applicant in his last 2 years of Egyptian Secondary Schoolالثانوية) العامة). Students who have taken either the IGCSE or SAT can also apply, however there is a very strict quota to the number of student who get accepted by the admission office which regulates entry into public universities. This quota does not apply to private universities. There are no entrance exams required for entry

The Byzantines were able to regain control of the country after a brief Persian invasion early in the seventh century, until in AD 639, Egypt wasabsorbed into the Islamic Empire by the Muslim Arabs. When they defeated the Byzantine Armies in Egypt, with the help of some revolutionary Egyptians, the Arabs brought Sunni Islam to the country. Early in this period, Egyptians began to blend their new faith with indigenous beliefs and practices that had survived through Coptic Christianity that was expanded in Egypt by the Byzantines, leading to various Sufi orders that have flourished to this day.[16] Muslim rulers nominated by the Islamic Caliphate remained in control of Egypt for the next six centuries, withCairo as the seat of the Caliphate under the Fatimids. With the end of the Kurdish Ayyubid dynasty, the Mamluks, a Turco-Circassian military caste, took control about AD 1250. By late 13th century, Egypt linked the Red Sea, India, Malaya, and East Indies.[17] The strategic positioning "assured importance in productive economy".[17] They continued to govern the country until the conquest of Egypt by the Ottoman Turks in 1517, after which it became a province of the Ottoman Empire. The mid-14th-Century Black Death killed about 40% of the country's population.[18] After the 15th century, the threat of military European Crusaders and Central Asian Mongols set the Egpytian system into decline.[17] The defensive militarization challenged the civil society and economic institutions.[17] The weakening of the economic system combined with the effects of Black Death left Egypt vulnerable to foreign invasion which can be seen with the Portuguese taking over their trade.[19] Egypt suffered six famines between 1687 and 1731.[20] The famine that afflicted Egypt in 1784 cost it roughly one-sixth of its population.[21]
