134-444: Leashes take many forms; for example: There are also bicycle dog leashes, especially designed for people who enjoy taking their pet on a ride with the bike. The leash is an aluminum tube with a plastic coated cable which runs down through the tube. It extends out of the tube end a couple of feet to allow for ease of movement for the dog. One end connects to the bike and the other to the dog's collar. This keeps them safely away from

268-656: A slave rebellion that started during the French Revolution of Saint-Domingue in 1791. Over the next decade, thousands of refugees landed in Louisiana from the island, including Europeans, Creoles, and Africans, some of the latter brought in by each free group. They greatly increased the French-speaking population in New Orleans and Louisiana, as well as the number of Africans, and the slaves reinforced African culture in

402-534: A "women's" bicycle, step-through frames are not common for larger frames. Step-throughs were popular partly for practical reasons and partly for social mores of the day. For most of the history of bicycles' popularity women have worn long skirts, and the lower frame accommodated these better than the top-tube. Furthermore, it was considered "unladylike" for women to open their legs to mount and dismount—in more conservative times women who rode bicycles at all were vilified as immoral or immodest. These practices were akin to

536-460: A 'straight handlebar' or 'riser bar' with varying degrees of sweep backward and centimeters rise upwards, as well as wider widths which can provide better handling due to increased leverage against the wheel. Saddles also vary with rider preference, from the cushioned ones favored by short-distance riders to narrower saddles which allow more room for leg swings. Comfort depends on riding position. With comfort bikes and hybrids, cyclists sit high over

670-469: A Scottish blacksmith, in 1839, although the claim is often disputed. He is also associated with the first recorded instance of a cycling traffic offense, when a Glasgow newspaper in 1842 reported an accident in which an anonymous "gentleman from Dumfries-shire... bestride a velocipede... of ingenious design" knocked over a little girl in Glasgow and was fined five shillings (equivalent to £30 in 2023). In

804-606: A Spanish expedition led by Pánfilo de Narváez located the mouth of the Mississippi River. In 1542, Hernando de Soto 's expedition skirted to the north and west of the state (encountering Caddo and Tunica groups) and then followed the Mississippi River down to the Gulf of Mexico in 1543. Spanish interest in Louisiana faded away for a century and a half. In the late 17th century, French and French Canadian expeditions, which included sovereign, religious and commercial aims, established

938-481: A bicycle at low to medium speeds of around 16–24 km/h (10–15 mph) uses only the power required to walk. Air drag, which is proportional to the square of speed, requires dramatically higher power outputs as speeds increase. If the rider is sitting upright, the rider's body creates about 75% of the total drag of the bicycle/rider combination. Drag can be reduced by seating the rider in a more aerodynamically streamlined position. Drag can also be reduced by covering

1072-496: A bike both stiff and compliant by manipulating the lay-up. Virtually all professional racing bicycles now use carbon fibre frames, as they have the best strength to weight ratio. A typical modern carbon fiber frame can weigh less than 1 kilogram (2.2 lb). Other exotic frame materials include titanium and advanced alloys. Bamboo , a natural composite material with high strength-to-weight ratio and stiffness has been used for bicycles since 1894. Recent versions use bamboo for

1206-485: A carriage. The design of the bicycle was an advance on the velocipede , although the words were used with some degree of overlap for a time. Other words for bicycle include "bike", "pushbike", "pedal cycle", or "cycle". In Unicode , the code point for "bicycle" is 0x1F6B2. The entity 🚲 in HTML produces 🚲. Although bike and cycle are used interchangeably to refer mostly to two types of two-wheelers,

1340-569: A conventional rear wheel brake, but not as effective as a front wheel brake. Bicycle suspension refers to the system or systems used to suspend the rider and all or part of the bicycle. This serves two purposes: to keep the wheels in continuous contact with the ground, improving control, and to isolate the rider and luggage from jarring due to rough surfaces, improving comfort. Bicycle suspensions are used primarily on mountain bicycles, but are also common on hybrid bicycles, as they can help deal with problematic vibration from poor surfaces. Suspension

1474-496: A cyclist to make fewer pedal turns to maintain a given speed, but with more effort per turn of the pedals. With a chain drive transmission, a chainring attached to a crank drives the chain, which in turn rotates the rear wheel via the rear sprocket(s) ( cassette or freewheel ). There are four gearing options: two-speed hub gear integrated with chain ring, up to 3 chain rings, up to 12 sprockets, hub gear built into rear wheel (3-speed to 14-speed). The most common options are either

1608-405: A desired area—as well as to tether them to a specific area, such as to a fencepost or tree trunk, so that they will remain stationary and not run away. Oftentimes, leashes are used to tether such animals when they require separation, examination, or work to be done to them, such as grooming and tacking up. Bicycle A bicycle , also called a pedal cycle , bike , push-bike or cycle ,

1742-418: A dog under control which can result in persons or other dogs being attacked. Aggressive dogs should not be walked with such a leash, and puppies should be kept closely to ensure their protection from various dangers such as cars. Dogs with a tendency to bolt without warning should be walked with caution, as a retractable lead can allow the dog to accelerate to significant speed before being stopped, presenting

1876-543: A foothold on the Mississippi River and Gulf Coast. With its first settlements, France laid claim to a vast region of North America and set out to establish a commercial empire and French nation stretching from the Gulf of Mexico to Canada. In 1682, the French explorer Robert Cavelier de La Salle named the region Louisiana to honor King Louis XIV of France. The first permanent settlement, Fort Maurepas (now Ocean Springs, Mississippi ),

2010-544: A growing town. This became a pattern repeated in New Orleans and other places, although the commodity crop in the south was primarily sugar cane. Louisiana's French settlements contributed to further exploration and outposts, concentrated along the banks of the Mississippi and its major tributaries, from Louisiana to as far north as the region called the Illinois Country , around present-day St. Louis, Missouri . The latter

2144-399: A high gear when cycling downhill, a medium gear when cycling on a flat road, and a low gear when cycling uphill. In a lower gear every turn of the pedals leads to fewer rotations of the rear wheel. This allows the energy required to move the same distance to be distributed over more pedal turns, reducing fatigue when riding uphill, with a heavy load, or against strong winds. A higher gear allows

2278-421: A leash, in a kennel, or in a cat-proof yard or house. Purposes of a leash include: preventing animals from frightening or biting people or other animals, defecating and urinating in inappropriate places, endangering traffic, digging up lawns , causing other damage, getting lost, and getting away from owners. Leashes also provide a clear method of communication and ensure control during training of dogs. In

2412-465: A narrow range of pedaling speeds, or cadence , a variable gear ratio helps a cyclist to maintain an optimum pedalling speed while covering varied terrain. Some, mainly utility, bicycles use hub gears with between 3 and 14 ratios, but most use the generally more efficient dérailleur system, by which the chain is moved between different cogs called chainrings and sprockets to select a ratio. A dérailleur system normally has two dérailleurs, or mechs, one at

2546-441: A popular form of recreation , and have been adapted for use as children's toys . Bicycles are used for fitness , military and police applications, courier services , bicycle racing , and artistic cycling . The basic shape and configuration of a typical upright or "safety" bicycle , has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since

2680-865: A proliferation of specialized bicycle types, improved bicycle safety , and riding comfort. Bicycles can be categorized in many different ways: by function, by number of riders, by general construction, by gearing or by means of propulsion. The more common types include utility bicycles , mountain bicycles , racing bicycles , touring bicycles , hybrid bicycles , cruiser bicycles , and BMX bikes . Less common are tandems , low riders , tall bikes , fixed gear , folding models , amphibious bicycles , cargo bikes , recumbents and electric bicycles . Unicycles , tricycles and quadracycles are not strictly bicycles, as they have respectively one, three and four wheels, but are often referred to informally as "bikes" or "cycles". A bicycle stays upright while moving forward by being steered so as to keep its center of mass over

2814-486: A rear hub or multiple chain rings combined with multiple sprockets (other combinations of options are possible but less common). The handlebars connect to the stem that connects to the fork that connects to the front wheel, and the whole assembly connects to the bike and rotates about the steering axis via the headset bearings. Three styles of handlebar are common. Upright handlebars , the norm in Europe and elsewhere until

2948-505: A rich southern biota , including birds such as ibises and egrets , many species of tree frogs —such as the state-recognized American green tree frog —and fish such as sturgeon and paddlefish . More elevated areas, particularly in the north, contain a wide variety of ecosystems such as tallgrass prairie , longleaf pine forest and wet savannas ; these support an exceptionally large number of plant species, including many species of terrestrial orchids and carnivorous plants . Over half

3082-516: A safety measure to protect the pet itself. Very often the collars are replaced with harnesses, because they avoid the dangers of collars which include escaping and running away or choking. Cats are more likely to not be willing to be walked in a harness than dogs are, and are considered to need up to months to be able to adjust to wearing a harness. Cat leashes come in a variety of colors, designs and models and are made of different materials. There are cat leashes made of leather, nylon and rope. Whereas

3216-560: A sales agent of the Coventry Sewing Machine Company (which soon became the Coventry Machinists Company ), brought a Michaux cycle to Coventry , England. His uncle, Josiah Turner, and business partner James Starley , used this as a basis for the 'Coventry Model' in what became Britain's first cycle factory. The dwarf ordinary addressed some of these faults by reducing the front wheel diameter and setting

3350-618: A similar pattern as in aircraft, the goal being high strength and low weight. Since the late 1930s alloy steels have been used for frame and fork tubes in higher quality machines. By the 1980s aluminum welding techniques had improved to the point that aluminum tube could safely be used in place of steel . Since then aluminum alloy frames and other components have become popular due to their light weight, and most mid-range bikes are now principally aluminum alloy of some kind. More expensive bikes use carbon fibre due to its significantly lighter weight and profiling ability, allowing designers to make

3484-599: A special envoy to Napoleon, to assist in obtaining New Orleans for the United States. Jefferson also raised the authorized expenditure to $ 10   million. However, on April 11, 1803, French foreign minister Talleyrand surprised Livingston by asking how much the United States was prepared to pay for the entirety of Louisiana, not just New Orleans and the surrounding area (as Livingston's instructions covered). Monroe agreed with Livingston that Napoleon might withdraw this offer at any time (leaving them with no ability to obtain

3618-518: A war or the loss of a single American life, and set a precedent for the purchase of territory. It opened the way for the eventual expansion of the United States across the continent to the Pacific Ocean. Shortly after the United States took possession, the area was divided into two territories along the 33rd parallel north on March 26, 1804, thereby organizing the Territory of Orleans to the south and

3752-511: A wheelset, especially in the context of ready-built "off the shelf", performance-oriented wheels. Tires vary enormously depending on their intended purpose. Road bicycles use tires 18 to 25 millimeters wide, most often completely smooth, or slick , and inflated to high pressure to roll fast on smooth surfaces. Off-road tires are usually between 38 and 64 mm (1.5 and 2.5 in) wide, and have treads for gripping in muddy conditions or metal studs for ice. Groupset generally refers to all of

3886-509: Is a human-powered or motor-assisted , pedal-driven , single-track vehicle , with two wheels attached to a frame , one behind the other. A bicycle rider is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe . By the early 21st century there were more than 1 billion bicycles. There are many more bicycles than cars . Bicycles are the principal means of transport in many regions. They also provide

4020-624: Is a Latin suffix that can refer to "information relating to a particular individual, subject, or place." Thus, roughly, Louis + ana carries the idea of "related to Louis." Once part of the French colonial empire , the Louisiana Territory stretched from present-day Mobile Bay to just north of the present-day Canada–United States border , including a small part of what are now the Canadian provinces of Alberta and Saskatchewan . The area of Louisiana

4154-498: Is applied to brake levers mounted on the handlebars and transmitted via Bowden cables or hydraulic lines to the friction pads, which apply pressure to the braking surface, causing friction which slows the bicycle down. A rear hub brake may be either hand-operated or pedal-actuated, as in the back pedal coaster brakes which were popular in North America until the 1960s. Track bicycles do not have brakes, because all riders ride in

4288-445: Is especially important on recumbent bicycles, since while an upright bicycle rider can stand on the pedals to achieve some of the benefits of suspension, a recumbent rider cannot. Basic mountain bicycles and hybrids usually have front suspension only, whilst more sophisticated ones also have rear suspension. Road bicycles tend to have no suspension. The wheel axle fits into fork ends in the frame and fork. A pair of wheels may be called

4422-534: Is estimated to have had a population of more than 20,000. The Plaquemine culture is considered ancestral to the historic Natchez and Taensa peoples, whose descendants encountered Europeans in the colonial era. By 1000 in the northwestern part of the state, the Fourche Maline culture had evolved into the Caddoan Mississippian culture. The Caddoan Mississippians occupied a large territory, including what

4556-967: Is now eastern Oklahoma, western Arkansas, northeast Texas , and northwest Louisiana. Archaeological evidence has demonstrated that the cultural continuity is unbroken from prehistory to the present. The Caddo and related Caddo-language speakers in prehistoric times and at first European contact were the direct ancestors of the modern Caddo Nation of Oklahoma of today. Significant Caddoan Mississippian archaeological sites in Louisiana include Belcher Mound Site in Caddo Parish and Gahagan Mounds Site in Red River Parish. Many current place names in Louisiana, including Atchafalaya , Natchitouches (now spelled Natchitoches ), Caddo, Houma , Tangipahoa , and Avoyel (as Avoyelles ), are transliterations of those used in various Native American languages. The first European explorers to visit Louisiana came in 1528 when

4690-453: Is softer. Leather is however more prone to be chewed when compared to nylon. The retractable dog leash is one of the most dangerous leashes for the dogs because they allow them to go as far as they want. Retractable leashes are usually made of nylon and the retractable device is made of plastic or a stronger composite. Although these leashes can be convenient for both the dog and the owner as it allows some control, they make it difficult to keep

4824-544: Is strong evidence of a growing cultural and political complexity. Many Coles Creek sites were erected over earlier Woodland period mortuary mounds. Scholars have speculated that emerging elites were symbolically and physically appropriating dead ancestors to emphasize and project their own authority. The Mississippian period in Louisiana was when the Plaquemine and the Caddoan Mississippian cultures developed, and

4958-471: Is the most efficient human-powered means of transportation in terms of energy a person must expend to travel a given distance. From a mechanical viewpoint, up to 99% of the energy delivered by the rider into the pedals is transmitted to the wheels, although the use of gearing mechanisms may reduce this by 10–15%. In terms of the ratio of cargo weight a bicycle can carry to total weight, it is also an efficient means of cargo transportation. A human traveling on

5092-571: Is the place of origin of the Mound Builders culture during the Middle Archaic period , in the 4th millennium BC . The sites of Caney and Frenchman's Bend have been securely dated to 5600–5000 BP (about 3700–3100 BC), demonstrating that seasonal hunter-gatherers from around this time organized to build complex earthwork constructions in what is now northern Louisiana.

Louisiana has a coastline with the Gulf of Mexico to the south; a large part of its eastern boundary is demarcated by the Mississippi River . Much of Louisiana's lands were formed from sediment washed down the Mississippi River, leaving enormous deltas and vast areas of coastal marsh and swamp . These contain

5360-516: The District of Columbia must be kept on a leash as well. They are also not permitted on school grounds when school is in session or on any public recreation area without a leash. Indiana is one of the states that has a restraint statute , which means that dogs must be restrained at all times. Otherwise, if the dog bites a person when not restrained the owner is subject to civil liability and criminal penalties. Dogs are allowed to run at large during

Previous slaves in Louisiana had been transported from French colonies in the West Indies. By the end of 1721, New Orleans counted 1,256 inhabitants, of whom about half were slaves. In 1724, the French government issued a law called the Code Noir ("Black Code" in English) which regulated

They were popular in a time when there were no cars on the market and the principal mode of transportation was horse-drawn vehicles , such the horse and buggy or the horsecar . Among the earliest clubs was The Bicycle Touring Club , which has operated since 1878. By the turn of the century, cycling clubs flourished on both sides of

6164-407: The seat further back. This, in turn, required gearing—effected in a variety of ways—to efficiently use pedal power. Having to both pedal and steer via the front wheel remained a problem. Englishman J.K. Starley (nephew of James Starley), J.H. Lawson, and Shergold solved this problem by introducing the chain drive (originated by the unsuccessful "bicyclette" of Englishman Henry Lawson), connecting

6298-517: The seat tube was added which created the modern bike's double-triangle diamond frame . Further innovations increased comfort and ushered in a second bicycle craze , the 1890s Golden Age of Bicycles . In 1888, Scotsman John Boyd Dunlop introduced the first practical pneumatic tire, which soon became universal. Willie Hume demonstrated the supremacy of Dunlop's tyres in 1889, winning the tyre's first-ever races in Ireland and then England. Soon after,

6432-443: The 1970s, curve gently back toward the rider, offering a natural grip and comfortable upright position. Drop handlebars "drop" as they curve forward and down, offering the cyclist best braking power from a more aerodynamic "crouched" position, as well as more upright positions in which the hands grip the brake lever mounts, the forward curves, or the upper flat sections for increasingly upright postures. Mountain bikes generally feature

In the late 18th century, the last Spanish governor of the Louisiana territory wrote: Truly, it is impossible for lower Louisiana to get along without slaves and with the use of slaves, the colony had been making great strides toward prosperity and wealth. When the United States purchased Louisiana in 1803, it was soon accepted that slaves could be brought to Louisiana as easily as they were brought to neighboring Mississippi , though it violated U.S. law to do so. Despite demands by United States Rep. James Hillhouse and by

After sales in New Orleans, steamboats operating on the Mississippi transported slaves upstream to markets or plantation destinations at Natchez and Memphis. Unusually for a slave-state, Louisiana harbored escaped Filipino slaves from the Manila Galleons . The members of the Filipino community were then commonly referred to as Manila men, or Manilamen, and later Tagalas , as they were free when they created

The word bicycle first appeared in English print in The Daily News in 1868, to describe "Bysicles and trysicles" on the "Champs Elysées and Bois de Boulogne". The word was first used in 1847 in a French publication to describe an unidentified two-wheeled vehicle, possibly

The French vélocipède , made of iron and wood, developed into the " penny-farthing " (historically known as an "ordinary bicycle", a retronym , since there was then no other kind). It featured a tubular steel frame on which were mounted wire-spoked wheels with solid rubber tires. These bicycles were difficult to ride due to their high seat and poor weight distribution . In 1868 Rowley Turner,

In addition, the carbon dioxide generated in the production and transportation of the food required by the bicyclist, per mile traveled, is less than 1 ⁄ 10 that generated by energy efficient motorcars. The great majority of modern bicycles have a frame with upright seating that looks much like

8710-405: The bicycle. Short-wheelbase or tall bicycles, when braking, can generate enough stopping force at the front wheel to flip longitudinally. The act of purposefully using this force to lift the rear wheel and balance on the front without tipping over is a trick known as a stoppie , endo, or front wheelie. The bicycle is extraordinarily efficient in both biological and mechanical terms. The bicycle

8844-577: The biggest slave market in the United States, which contributed greatly to the economy of the city and of the state. New Orleans had become one of the wealthiest cities, and the third largest city, in the nation. The ban on the African slave trade and importation of slaves had increased demand in the domestic market. During the decades after the American Revolutionary War, more than one million enslaved African Americans underwent forced migration from

According to the North Carolina law, dogs are allowed to run at large during the night only if they are accompanied by their owner or a person who has received the owner's permission to do so. Ohio law requires one to "keep the dog under the reasonable control of some person," but does not require a leash except for "any female dog … at any time

9782-436: The desired New Orleans area), and that approval from President Jefferson might take months, so Livingston and Monroe decided to open negotiations immediately. By April 30, they closed a deal for the purchase of the entire Louisiana territory of 828,000 square miles (2,100,000 km ) for sixty million Francs (approximately $ 15   million). Part of this sum, $ 3.5   million, was used to forgive debts owed by France to

9916-433: The dog in public places. Having the dog wear a leash is a way of protecting the dog and other persons (e.g., if the dog runs away and bites someone). The length is one of the important aspects of the leash. The length of the leash must be chosen according to the size of the dog and it is important because it allows a good control. Leashes should not be either too long or too short. Too-long leashes do not provide good control of

10050-456: The dog is in heat." There are additional provisions for "dangerous dogs" that have injured a person or killed another dog. Some Oregon counties and cities have leash ordinances that can be used to hold dog owners responsible for injuries resulting from their animal attacking or biting a person while running at large. These ordinances expand upon Oregon law, under which dog owners have limited responsibility for injuries caused by their dogs unless

10184-409: The dog. The material of which the leash is made of is not of great importance as long as the leash does not show evidence of wear or fraying. Therefore, leashes should be periodically checked to ensure they are maintained in proper condition. An important aspect of dog leashes is their sturdiness. Although rope leashes are quite cheap , they are vulnerable to chewing and fraying and are not amongst

10318-413: The early 1860s, Frenchmen Pierre Michaux and Pierre Lallement took bicycle design in a new direction by adding a mechanical crank drive with pedals on an enlarged front wheel (the velocipede ). This was the first in mass production. Another French inventor named Douglas Grasso had a failed prototype of Pierre Lallement's bicycle several years earlier. Several inventions followed using rear-wheel drive,

10452-756: The first platform mounds at ritual centers were constructed for the developing hereditary political and religious leadership. By 400 the Late Woodland period had begun with the Baytown culture , Troyville culture , and Coastal Troyville during the Baytown period and were succeeded by the Coles Creek cultures . Where the Baytown peoples built dispersed settlements, the Troyville people instead continued building major earthwork centers. Population increased dramatically and there

10586-406: The first chain-driven bike. These upright bicycles almost always feature the diamond frame , a truss consisting of two triangles: the front triangle and the rear triangle. The front triangle consists of the head tube, top tube, down tube, and seat tube. The head tube contains the headset , the set of bearings that allows the fork to turn smoothly for steering and balance. The top tube connects

10720-507: The first people in the area of Louisiana to make large amounts of pottery. These cultures lasted until 200 AD. The Middle Woodland period started in Louisiana with the Marksville culture in the southern and eastern part of the state, reaching across the Mississippi River to the east around Natchez, and the Fourche Maline culture in the northwestern part of the state. The Marksville culture

10854-534: The first two African slaves to Louisiana in 1708, transporting them from a French colony in the West Indies. In 1709, French financier Antoine Crozat obtained a monopoly of commerce in La Louisiane , which extended from the Gulf of Mexico to what is now Illinois . According to historian Hugh Thomas , "that concession allowed him to bring in a cargo of blacks from Africa every year". Starting in 1719, traders began to import slaves in higher numbers; two French ships,

10988-491: The frame-mounted cranks to the rear wheel. These models were known as safety bicycles , dwarf safeties, or upright bicycles for their lower seat height and better weight distribution, although without pneumatic tires the ride of the smaller-wheeled bicycle would be much rougher than that of the larger-wheeled variety. Starley's 1885 Rover , manufactured in Coventry is usually described as the first recognizably modern bicycle. Soon

11122-446: The front to select the chainring and another at the back to select the sprocket. Most bikes have two or three chainrings, and from 5 to 11 sprockets on the back, with the number of theoretical gears calculated by multiplying front by back. In reality, many gears overlap or require the chain to run diagonally, so the number of usable gears is fewer. An alternative to chaindrive is to use a synchronous belt. These are toothed and work much

11256-410: The head tube to the seat tube at the top, and the down tube connects the head tube to the bottom bracket . The rear triangle consists of the seat tube and paired chain stays and seat stays. The chain stays run parallel to the chain , connecting the bottom bracket to the rear dropout , where the axle for the rear wheel is held. The seat stays connect the top of the seat tube (at or near the same point as

11390-474: The influence of New England Federalists in national affairs. President Jefferson was an enthusiastic supporter of westward expansion, and held firm in his support for the treaty. Despite Federalist objections, the U.S. Senate ratified the Louisiana treaty on October 20, 1803. By statute enacted on October 31, 1803, President Thomas Jefferson was authorized to take possession of the territories ceded by France and provide for initial governance. A transfer ceremony

11524-471: The interaction of whites (blancs) and blacks (noirs) in its colony of Louisiana (which was much larger than the current state of Louisiana). After the Sale of Louisiana , French Law survived in the Louisiana, such as the prohibition and outlaw of any cruel punishment. Fugitive slaves, called maroons , could easily hide in the backcountry of the bayous and survive in small settlements. The word "maroon" comes from

11658-520: The islands of Martinique and Guadeloupe to the French. Napoleon looked upon Louisiana as a depot for these sugar islands, and as a buffer to U.S. settlement. In October 1801 he sent a large military force to take back Saint-Domingue, then under control of Toussaint Louverture after the Haitian Revolution . When the army led by Napoleon's brother-in-law Leclerc was defeated, Napoleon decided to sell Louisiana. Thomas Jefferson , third president of

11792-449: The leather leash is one of the best qualities because of the characteristics of the material, it is also one of the most expensive and not very comfortable for the cat at the same time. Nylon cat leashes and harnesses are, however, more elastic, and thus more comfortable and also provide more control. Leashes are used on large animals—such as bovids , camelids , and equids —to lead them so that they will be forced to follow and come to

11926-402: The mechanism is contained within the wheel hub, or disc brakes, where pads act on a rotor attached to the hub. Most road bicycles use rim brakes, but some use disc brakes. Disc brakes are more common for mountain bikes, tandems and recumbent bicycles than on other types of bicycles, due to their increased power, coupled with an increased weight and complexity. With hand-operated brakes, force

12060-540: The modern state of Louisiana. The French settlement had two purposes: to establish trade with the Spanish in Texas via the Old San Antonio Road, and to deter Spanish advances into Louisiana. The settlement soon became a flourishing river port and crossroads, giving rise to vast cotton kingdoms along the river that were worked by imported African slaves. Over time, planters developed large plantations and built fine homes in

12194-405: The most recommended types of leashes. Nylon leashes are recommended; this material provides a bit of elasticity which is meant to result in more comfort for the dog. On the other hand, nylon leashes can cause chafe or can cut into the skin of the dog. Leather leashes are often preferred over the nylon ones because of the resistance of the material and because it becomes more flexible with age and it

12328-656: The night in Kentucky only if they are accompanied by and under control of their owner. According to the leash laws of Louisiana , dogs are prohibited to run at large at all times of the day. The same law applies in Maine, where the only exception is for hunting dogs . Missouri legislation requires that dogs are kept in leashes that are no longer than 10 feet when they are in state parks or on historic sites. Also, dogs that have rabies are not permitted to run at large. In Nebraska , dogs may run at large only in counties where

12462-623: The northern and eastern bounds of his domain as the Wabash valley up to the mouth of the Vermilion River (near present-day Danville, Illinois ); from there, northwest to le Rocher on the Illinois River , and from there west to the mouth of the Rock River (at present day Rock Island, Illinois ). Thus, Vincennes and Peoria were the limit of Louisiana's reach; the outposts at Ouiatenon (on

12596-531: The older practice of riding horse sidesaddle . Another style is the recumbent bicycle . These are inherently more aerodynamic than upright versions, as the rider may lean back onto a support and operate pedals that are on about the same level as the seat. The world's fastest bicycle is a recumbent bicycle but this type was banned from competition in 1934 by the Union Cycliste Internationale . Historically, materials used in bicycles have followed

12730-615: The oldest settlement of Asians in the United States in the village of Saint Malo, Louisiana , the inhabitants of which, even joined the United States in the War of 1812 against the British Empire while they were being led by the French-American Jean Lafitte . Spanish occupation of Louisiana lasted from 1769 to 1800. Beginning in the 1790s, waves of immigration took place from Saint-Domingue as refugees poured over following

12864-504: The one whose mentality and customs influenced Louisiana the most." When the United States won its independence from Great Britain in 1783, one of its major concerns was having a European power on its western boundary, and the need for unrestricted access to the Mississippi River. As American settlers pushed west, they found that the Appalachian Mountains provided a barrier to shipping goods eastward. The easiest way to ship produce

12998-424: The overall weight of the bicycle. A recumbent bicycle has a reclined chair-like seat that some riders find more comfortable than a saddle, especially riders who suffer from certain types of seat, back, neck, shoulder, or wrist pain. Recumbent bicycles may have either under-seat or over-seat steering . Bicycle brakes may be rim brakes, in which friction pads are compressed against the wheel rims; hub brakes, where

13132-815: The owner was aware that the animal is abnormally dangerous. Pennsylvania legislation states that dogs must be confined or firmly secured or reasonably controlled by a person, within the property of the owner. Tennessee law prohibits dogs to run at large except in cases in which dogs are engaged in legal hunting or herding. West Virginia and Wisconsin are states that do not have a law that requires dogs to be leashed. Still, they do have laws that hold dog owners and keepers liable for all damages caused by dogs that are permitted to run at large. Different law applies to dangerous dogs and female dogs as in different states they are prohibited to run at large at all times. Also, in states such as Connecticut and Louisiana, guide dogs must also be leashed. Dog leashes are used to walk

13266-559: The pamphleteer Thomas Paine to enforce existing federal law against slavery in the newly acquired territory, slavery prevailed because it was the source of great profits and the lowest-cost labor. At the start of the 19th century, Louisiana was a small producer of sugar with a relatively small number of slaves, compared to Saint-Domingue and the West Indies. It soon thereafter became a major sugar producer as new settlers arrived to develop plantations. William C. C. Claiborne , Louisiana's first United States governor, said African slave labor

13400-576: The peoples adopted extensive maize agriculture, cultivating different strains of the plant by saving seeds, selecting for certain characteristics, etc. The Plaquemine culture in the lower Mississippi River Valley in western Mississippi and eastern Louisiana began in 1200 and continued to about 1600. Examples in Louisiana include the Medora site , the archaeological type site for the culture in West Baton Rouge Parish whose characteristics helped define

13534-405: The pet whereas too-short leashes are uncomfortable for both the dog and the owner. The perfect leash can restrain the dog but at the same time is not viewed as a punishment for the pet. High quality dog leashes have a good quality metal clip and they can be made of leather, nylon or even chain . The metal clip must securely fasten to a metal ring on the collar in order to maintain good control of

13668-440: The pet. An exception is for farm dogs. Also, during the night dogs must be kept in an enclosure from which they cannot escape, firmly secured with a collar or chain or other device, so they cannot stray from the premises , or are under the reasonable control of the owner or custodian. If an owner does not respect these laws and if the dog bites someone, the owner is subject to civil liability and for fines of up to $ 1,500. Dogs in

13802-464: The population does not reach 80,000. New Hampshire legislation does not allow dogs to run at large unless they are accompanied by their owner or custodian or when dogs are used for training or are trained for hunting, herding or exhibitions . Illinois legislation prohibits owners from walking their dogs when they are not in a leash. Dogs in New York must be restrained or confined at all times of

13936-434: The possibility of injury to both dog and owner. Some leashes are made of reflective materials and are suitable for walking the dog at night. They are convenient because they make the dog and the owner much more visible in the traffic , reducing the likelihood of accidents. Cat leashes are used with the purpose of preventing the cat getting lost. Unlike dogs, cats rarely attack persons on the street, so cat leashes are mainly

14070-585: The pressure for Anglicization , and in 1921, English was shortly made the sole language of instruction in Louisiana schools before a policy of multilingualism was revived in 1974. Louisiana has never had an official language, and the state constitution enumerates "the right of the people to preserve, foster, and promote their respective historic, linguistic, and cultural origins." Based on national averages, Louisiana frequently ranks low among U.S. states in terms of health, education, and development, with high rates of poverty and homicide . In 2018, Louisiana

14204-490: The primary frame with glued metal connections and parts, priced as exotic models. The drivetrain begins with pedals which rotate the cranks , which are held in axis by the bottom bracket. Most bicycles use a chain to transmit power to the rear wheel. A very small number of bicycles use a shaft drive to transmit power, or special belts. Hydraulic bicycle transmissions have been built, but they are currently inefficient and complex. Since cyclists' legs are most efficient over

14338-525: The rear freewheel was developed, enabling the rider to coast. This refinement led to the 1890s invention of coaster brakes . Dérailleur gears and hand-operated Bowden cable -pull brakes were also developed during these years, but were only slowly adopted by casual riders. The Svea Velocipede with vertical pedal arrangement and locking hubs was introduced in 1892 by the Swedish engineers Fredrik Ljungström and Birger Ljungström . It attracted attention at

14472-447: The rest of the southern U.S., Louisiana is multilingual and multicultural, reflecting an admixture of Louisiana French ( Cajun , Creole ), Spanish , French Canadian , Acadian , Saint-Domingue Creole , Native American , and West African cultures (generally the descendants of slaves stolen in the 18th century); more recent migrants include Filipinos and Vietnamese. In the post–Civil War environment , Anglo-Americans increased

14606-466: The rider to mount and dismount in a dignified way while wearing a skirt or dress. While some women's bicycles continue to use this frame style, there is also a variation, the mixte , which splits the top tube laterally into two thinner top tubes that bypass the seat tube on each side and connect to the rear fork ends. The ease of stepping through is also appreciated by those with limited flexibility or other joint problems. Because of its persistent image as

14740-429: The river for U.S. commerce. Livingston was authorized to pay up to $ 2   million. An official transfer of Louisiana to French ownership had not yet taken place, and Napoleon's deal with the Spanish was a poorly kept secret on the frontier. On October 18, 1802, however, Juan Ventura Morales, acting intendant of Louisiana, made public the intention of Spain to revoke the right of deposit at New Orleans for all cargo from

14874-550: The river would be delayed until later in the decade. In 1765, during Spanish rule, several thousand Acadians from the French colony of Acadia (now Nova Scotia , New Brunswick, and Prince Edward Island ) made their way to Louisiana after having been expelled from Acadia by the British government after the French and Indian War. They settled chiefly in the southwestern Louisiana region now called Acadiana . The governor Luis de Unzaga y Amézaga , eager to gain more settlers, welcomed

15008-402: The same as a chain—popular with commuters and long distance cyclists they require little maintenance. They cannot be shifted across a cassette of sprockets, and are used either as single speed or with a hub gear. Different gears and ranges of gears are appropriate for different people and styles of cycling. Multi-speed bicycles allow gear selection to suit the circumstances: a cyclist could use

15142-416: The same direction around a track which does not necessitate sharp deceleration. Track riders are still able to slow down because all track bicycles are fixed-gear, meaning that there is no freewheel. Without a freewheel, coasting is impossible, so when the rear wheel is moving, the cranks are moving. To slow down, the rider applies resistance to the pedals, acting as a braking system which can be as effective as

15276-604: The seat, their weight directed down onto the saddle, such that a wider and more cushioned saddle is preferable. For racing bikes where the rider is bent over, weight is more evenly distributed between the handlebars and saddle, the hips are flexed, and a narrower and harder saddle is more efficient. Differing saddle designs exist for male and female cyclists, accommodating the genders' differing anatomies and sit bone width measurements, although bikes typically are sold with saddles most appropriate for men. Suspension seat posts and seat springs provide comfort by absorbing shock but can add to

15410-418: The situation of hunting . Still, if the dog has vicious propensities and the owner still allows it to run at large and a person is bitten, the owner can be fined for up to $ 1,000 and is also liable for 6 months of prison unless the victim has abused the dog and provoked the harmful behavior. In Delaware , dogs are not allowed to run at large unless in situations when the owner is present and has control over

15544-549: The size of the country. Jefferson's political opponents in the Federalist Party argued the Louisiana purchase was a worthless desert, and that the U.S. constitution did not provide for the acquisition of new land or negotiating treaties without the consent of the federal legislature. What really worried the opposition was the new states which would inevitably be carved from the Louisiana territory, strengthening western and southern interests in U.S. Congress , and further reducing

15678-472: The state is forested. Louisiana is situated at the confluence of the Mississippi river system and the Gulf of Mexico. Its location and biodiversity attracted various indigenous groups thousands of years before Europeans arrived in the 17th century. Louisiana has eighteen Native American tribes—the most of any southern state—of which four are federally recognized and ten are state-recognized. The French claimed

15812-551: The state. The city of modern–day Epps developed near it. The Poverty Point culture may have reached its peak around 1500 BC, making it the first complex culture, and possibly the first tribal culture in North America. It lasted until approximately 700 BC. The Poverty Point culture was followed by the Tchefuncte and Lake Cormorant cultures of the Tchula period , local manifestations of Early Woodland period . The Tchefuncte culture were

15946-456: The terms still vary across the world. In India, for example, a cycle refers only to a two-wheeler using pedal power whereas the term bike is used to describe a two-wheeler using internal combustion engine or electric motors as a source of motive power instead of motorcycle/motorbike. The " dandy horse ", also called Draisienne or Laufmaschine ("running machine"), was the first human means of transport to use only two wheels in tandem and

16080-477: The territory in 1682, and it became the political, commercial, and population center of the larger colony of New France . From 1762 to 1801 Louisiana was under Spanish rule, briefly returning to French rule before being sold by Napoleon to the U.S. in 1803. It was admitted to the Union in 1812 as the 18th state. Following statehood, Louisiana saw an influx of settlers from the eastern U.S. as well as immigrants from

16214-446: The top tube) to the rear fork ends. Historically, women's bicycle frames had a top tube that connected in the middle of the seat tube instead of the top, resulting in a lower standover height at the expense of compromised structural integrity, since this places a strong bending load in the seat tube, and bicycle frame members are typically weak in bending. This design, referred to as a step-through frame or as an open frame , allows

16348-451: The upper Wabash near present-day Lafayette, Indiana ), Chicago, Fort Miamis (near present-day Fort Wayne, Indiana ), and Prairie du Chien, Wisconsin , operated as dependencies of Canada. The settlement of Natchitoches (along the Red River in present-day northwest Louisiana) was established in 1714 by Louis Juchereau de St. Denis , making it the oldest permanent European settlement in

16482-462: The west, Arkansas to the north, and Mississippi to the east. Of the 50 U.S. states , it ranks 20th in land area and the 25th in population , with roughly 4.6 million residents. Reflecting its French heritage , Louisiana is the only U.S. state with political subdivisions termed parishes , which are equivalent to counties , making it one of only two U.S. states not subdivided into counties (the other being Alaska and its boroughs ). Baton Rouge

16616-407: The wheels. This steering is usually provided by the rider, but under certain conditions may be provided by the bicycle itself. The combined center of mass of a bicycle and its rider must lean into a turn to successfully navigate it. This lean is induced by a method known as countersteering , which can be performed by the rider turning the handlebars directly with the hands or indirectly by leaning

16750-477: Was built about 5400 BP (3500 BC). These discoveries overturned previous assumptions in archaeology that such complex mounds were built only by cultures of more settled peoples who were dependent on maize cultivation. The Hedgepeth Site in Lincoln Parish is more recent, dated to 5200–4500 BP (3300–2600 BC). Nearly 2,000 years later, Poverty Point was built; it is the largest and best-known Late Archaic site in

16884-403: Was founded in 1699 by Pierre Le Moyne d'Iberville , a French military officer from New France . By then the French had also built a small fort at the mouth of the Mississippi at a settlement they named La Balise (or La Balize) , " seamark " in French. By 1721, they built a 62-foot (19 m) wooden lighthouse-type structure here to guide ships on the river. A royal ordinance of 1722—following

17018-422: Was held in New Orleans on November 29, 1803. Since the Louisiana territory had never officially been turned over to the French, the Spanish took down their flag, and the French raised theirs. The following day, General James Wilkinson accepted possession of New Orleans for the United States. The Louisiana Territory, purchased for less than three cents an acre, doubled the size of the United States overnight, without

17152-630: Was invented by the German Baron Karl von Drais . It is regarded as the first bicycle and von Drais is seen as the "father of the bicycle", but it did not have pedals. Von Drais introduced it to the public in Mannheim in 1817 and in Paris in 1818. Its rider sat astride a wooden frame supported by two in-line wheels and pushed the vehicle along with his or her feet while steering the front wheel. The first mechanically propelled, two-wheeled vehicle may have been built by Kirkpatrick MacMillan ,

17286-652: Was named after the Marksville Prehistoric Indian Site in Avoyelles Parish . These cultures were contemporaneous with the Hopewell cultures of present-day Ohio and Illinois , and participated in the Hopewell Exchange Network. Trade with peoples to the southwest brought the bow and arrow . The first burial mounds were built at this time. Political power began to be consolidated, as

17420-502: Was needed because white laborers "cannot be had in this unhealthy climate." Hugh Thomas wrote that Claiborne was unable to enforce the abolition of the Atlantic slave trade, which the U.S. and Great Britain enacted in 1807. The United States continued to protect the domestic slave trade, including the coastwise trade—the transport of slaves by ship along the Atlantic Coast and to New Orleans and other Gulf ports. By 1840, New Orleans had

17554-437: Was ranked as the least healthy state in the country, with high levels of drug-related deaths . It also has had the highest homicide rate in the United States since at least the 1990s. Louisiana was named after Louis XIV , King of France from 1643 to 1715. When René-Robert Cavelier, Sieur de La Salle claimed the territory drained by the Mississippi River for France, he named it La Louisiane . The suffix –ana (or –ane)

17688-457: Was settled by French colonists from Illinois. Initially, Mobile and then Biloxi served as the capital of La Louisiane. Recognizing the importance of the Mississippi River to trade and military interests, and wanting to protect the capital from severe coastal storms, France developed New Orleans from 1722 as the seat of civilian and military authority south of the Great Lakes. From then until

17822-505: Was stimulated by the widespread advertising, production, and use of these devices. More than 1 billion bicycles have been manufactured worldwide as of the early 21st century. Bicycles are the most common vehicle of any kind in the world, and the most numerous model of any kind of vehicle, whether human-powered or motor vehicle , is the Chinese Flying Pigeon , with numbers exceeding 500 million. The next most numerous vehicle,

17956-549: Was to use a flatboat to float it down the Ohio and Mississippi rivers to the port of New Orleans, where goods could be put on ocean-going vessels. The problem with this route was that the Spanish owned both sides of the Mississippi below Natchez . Napoleon's ambitions in Louisiana involved the creation of a new empire centered on the Caribbean sugar trade . By the terms of the Treaty of Amiens of 1802, Great Britain returned control of
