Printers In 1953, the first high-speed printer was developed by Remington-Rand for use on the Univac computer. In 1938, Chester Carlson invented a dry printing process called electrophotography commonly called a Xerox, the foundation technology for laser printers to come. The original laser printer called EARS was developed at the Xerox Palo Alto Research Center beginning in 1969 and completed in November, 1971. Xerox Engineer, Gary Starkweather adapted Xerox copier technology adding a laser beam to it to come up with the laser printer. According to Xerox, "The Xerox 9700 Electronic Printing System, the first xerographic laser printer product, was released in 1977. The 9700, a direct descendent from the original PARC "EARS" printer which pioneered in laser scanning optics, character generation electronics, and page-formatting software, was the first product on the market to be enabled by PARC research." According to IBM, "the very first IBM 3800 was installed in the central accounting office at F. W. Woolworth’’s North American data center in Milwaukee, Wisconsin in 1976." The IBM 3800 Printing System was the industry’’s first high-speed, laser printer. A laser printer that operated at speeds of more than 100 impressions-per-minute. It was the first printer to combine laser technology and electrophotography according to IBM. In 1992, Hewlett-Packard released the popular LaserJet 4, the first 600 by 600 dots per inch resolution laser printer. In 1976, the inkjet printer was invented, but it took until 1988 for the inkjet to become a home consumer item with Hewlett-Parkard's release of the DeskJet inkjet printer, priced at a whopping $1000.

The Story of How Canada Got Its Name

The Story of How Canada Got Its Name The name Canada comes from kanata, the Iroquois-Huron word for village or settlement. The Iroquois  used the word to describe the village of Stadacona, present-day Quebec City. During his second voyage to New France  in 1535, French explorer Jacques Cartier sailed up the Saint Lawrence River for the first time. The Iroquois pointed him in the direction of kanata, the village at Stadacona, which Cartier misinterpreted as a reference to  both the village of Stadacona and the wider area subject to Donnacona, the Stadacona Iroquois chief. During Cartiers 1535 trip, the French established along the Saint Lawrence the colony of Canada, the first colony in what the French called New France. Use of Canada gained prominence from there.   The Name Canada Takes Hold (1535 to the 1700s) By 1545, European books and maps had begun referring to this small region along the  Saint Lawrence River  as Canada. By 1547, maps were showing the name Canada as everything north of the St. Lawrence River. Cartier referred to the St. Lawrence River as la rivià ¨re du Canada  (the river of Canada),  and the name began to take hold. Even though the French called the region New France, by 1616 the entire area along the great river of Canada and the Gulf of Saint Lawrence was still called Canada. As the country expanded to the west and the south in the 1700s, Canada was the unofficial name of an area spanning the American Midwest, extending as far south as what is now the state of Louisiana. After the British conquered New France in 1763, the colony  was renamed  the Province of Quebec. Then, as British loyalists headed north during and after the American Revolutionary War, Quebec was divided into two parts. Canada Becomes Official In 1791, the Constitutional Act, also called the Canada Act, divided the Province of Quebec into the colonies of Upper Canada and Lower Canada. This marked the first official use of the name Canada. In 1841, the two Quebecs  were united again, this time as the Province of Canada. On July 1, 1867, Canada  was adopted as the legal name for the new country of Canada upon its confederation. On that date, the Confederation Convention formally combined the Province of Canada, which included Quebec and Ontario, with Nova Scotia and New Brunswick as one Dominion under the name of Canada. This produced the physical configuration of modern Canada, which is today the second largest country in the world by area (after Russia).  July 1 is still celebrated as Canada Day. Other Names Considered for Canada Canada wasnt the only name considered for the new dominion, although it was ultimately chosen by unanimous vote at the Confederation Convention.   Several other names were suggested for the northern half of the North American continent leading up to confederation, some of which were later repurposed elsewhere in the country. The list included Anglia (a medieval Latin name for England), Albertsland, Albionora, Borealia, Britannia, Cabotia, Colonia, and Efisga, an acronym for the first letters of the countries  England, France, Ireland, Scotland, Germany, with the A for Aboriginal. Other names floated for consideration were Hochelaga, Laurentia (a geological name for part of North America), Norland, Superior, Transatlantia, Victorialand and Tuponia, an acrostic for The United Provinces of North America. This is how the Canadian government remembers the name debate on ​Canada.ca: The debate was placed in perspective by Thomas D’Arcy McGee, who declared on February 9, 1865: â€Å"I read in one newspaper not less than a dozen attempts to derive a new name. One individual chooses Tuponia and another Hochelaga as a suitable name for the new nationality. Now I ask any honourable member of this House how he would feel if he woke up some fine morning and found himself instead of a Canadian, a Tuponian or a Hochelagander.† Fortunately for posterity, McGee’s wit and reasoning–along with common sense–prevailed... The Dominion of Canada Dominion became part of the name instead of kingdom as a clear reference that Canada was under British rule but still its own separate entity. After World War II, as Canada became more autonomous, the full name Dominion of Canada was used less and less. The countrys name was officially changed to Canada in  1982  when the Canada Act was passed, and its been known by that name ever since. The Fully Independent Canada Canada did not become fully independent from Britain until 1982 when  its constitution was patriated under the Constitution Act of 1982, or the Canada Act, The act essentially transferred the countrys highest law, the British North America Act, from the authority of the British Parliament- a connection from the colonial past- to  Canadas  federal and provincial legislatures. The document contains the  original statute that established the  Canadian Confederation  in 1867 (the British  North America  Act),  amendments  that the British Parliament made to it over the years, and Canadas Charter of Rights and Freedoms, the result of fierce negotiations between the federal and provincial governments that set down basic rights ranging from freedom of religion to linguistic and educational rights based on the test of numbers. Through it all, the name Canada has remained.

Selective Incorporation Essay Example | Topics and Well Written Essays - 1000 words

Selective Incorporation - Essay Example Selective incorporation has been applied in numerous instances to protect and uphold human rights especially in a criminal proceeding. This was done during the tenure of chief justice Earl Warren when the rights enjoyed by the criminal defendants were expanded. For example, in the case of Gideon v Wainwright, the defendant was accused of breaking into bay harbor pool hall and stealing cigarette change from the vending machines.Though Gideon requested a lawyer to be appointed by the states, the state of Florida declined, stating that this can only be done in capital offenses. However, the Supreme Court ruled that the 14th amendment allowed all defendants to access the services of an attorney. This right, as stated in the sixth amendment of the constitution was meant to protect the rights of the accused and ensure the provision of free trails. The Miranda v Arizona established the principle of equal access to legal representation during a trial and the determination was based on select ive incorporation. Failure to inform a suspect of his right during arrest constitutes legal subjugation of their legal rights as contained in the first 8 amendments and the 14th amendment of the United States Constitution. The 5th amendment of the united states indicates that a suspect has a right to remain silent during arrest as any pronouncement made can be used against them in the determination of the case.The sixth amendment indicates that a legal counsel must represent suspects during the determination of their cases.

How did the economic development of the Gilded age affect American Essay

How did the economic development of the Gilded age affect American Freedom - Essay Example It entailed a notion that such approach to spontaneous progress determines allocation of power and social security. In this regard, reformists of the period were led to conceive that potential peril exists with the significant concern that as a response to it, people of the lower class may act in tumultuous aggression in exercising their democratic right over to suppress individual economic growth thinking that liberty of acquisition of rights to property (Foner), particularly with those who could afford, would only emphasize inequality among social divisions and thus create on appropriating amount of common interests. Progression of economic development enabled Americans to adapt to the concept and application of ‘Social Darwinism’ in their everyday living since the competition to acquire relative or higher advantage in upgrading social and economic status in American society had apparently become essential. With the rapidly growing rate of capital formation, GDP, and wages (Gilded), this condition concretized the effect of social freedom and transformation across vast critical regions of societies in U.S. in which most citizens began expressing individual or collective views by putting up labor unions that served to oppose severely improper conditions, shift schedules, loads, and unjust wages at work. Democracy was put in wide and intense practice of articulating protest with the desire to take part in the evolving process of industrial growth. In this endeavor, they sought to be assured as well of experiencing freedom from any form of injustice or oppression of employers who were p redictably consumed by the principle of capitalism or profit-orientation for use in business that required irrational gravity of labor at the expense of either skilled or unskilled workers (Gilded). Since Social Darwinism in human society advocates natural selection without interference from the government, the ensuing crisis with inequality due to the fast rate

Ashford University Essay Example for Free

Ashford University Essay Pornography is very addictive and can destroy someone’s marriage and life. This addiction can, and in many cases, lead to someone committing very serious sexual crimes. People who look at porn often look for more perversity in different areas. The resources from which I found my information on is the Ashford Library and a couple credible internet sites. There are several reasons why people turn to porn. Some reasons are for seeing their own fantasies acted out because they can’t act them out with their own partner / spouse, some people want to avoid intimacy within their own relationship for personal reasons, some just do it for personal pleasure. But for whatever reason, there is always a consequence that will follow. According to the American Academy of Matrimonial Lawyers (AAML), 56% of divorces occur because one spouse keeps returning to a pornographic website. These men / women feel as though they are being compared to these people in the pornographic films or pictures. Whether it’s the man or the woman who is watching porn inside the marriage, in most cases, they are doing this against their spouses wishes. This leads to lack of intimacy, low self esteem, shame, and lack of trust. This also makes the spouse feel as if they are no longer found attractive. â€Å"Just ask your spouse how confident they feel being naked in front of you after you’ve looked at pornography and you’ll understand this one.† ( http://www.debttolife.com ). Many people say that they introduce porn into their marriage to spice their love life up but in the end all this does is slowly destroy the intimacy that was there. After watching pornography people’s views are completely changed. After being exposed to R-  rated material men no longer see their spouse as they once did. They look at them now more as an object rather than an individual that they love. Studies have shown (http://www.webmd.com ) that pornography can be just the same as an addiction. Some experts who have studied porn addiction have called the effects of porn on the brain toxic and also compared it to the deadly drug cocaine (WebMD, 2014). These addicts no longer just suffer from nights without sleep or unpaid credit card bills but they are also becoming more engaged in group sex and sexual contact with animals. Other effects that have surfaced from pornography include acting out what they have seen in porn material, sexual acts towards children both boys and girls, and rape using foreign materials / objects. (The Forerunner, 1991). Child pornography is a disgusting fact that we hear about every day. â€Å"Child pornography is the visual depiction of sexually explicit conduct includes acts such as intercourse, bestiality and masturbation as well as lascivious exhibition of the genitals or pubic area.† (Pulido, 2013). Recently, there were 71 people, 70 men and 1 woman, who were arrested in child pornography charges. Among that 70 included a police officer, a paramedic, a rabbi, an airline pilot, an architect, and a Boy Scout leader. Many of these people who were arrest had search the phrases â€Å"real child rape† and â€Å"family sex† into their computers search engines turning up extremely disturbing images (Hays, 2014). With so many people connected to the internet it has made this type of crime so easy. Perverts and pedophiles search the web everyday to find new victims. â€Å"The victims are getting younger, and the images more violent.†(Flack). When a picture of a child circles the internet going from one person to another, that child is being re-abused. No child should have to endear that type of suffering, never! A peer to – peer, also known as P2P, file sharing network, that allows people to share music, videos, and pictures, was under investigation by authorizes and had 3,000 child pornography consumers with tens of thousands of child pornographic images  traded. â€Å"The investigation began after agents, using software available to law enforcement, were able to trace f iles of child pornography to an I.P. address on a computer used by Brian Fanelli, 54, who until January was the police chief of Mount Pleasant, N.Y† (Berger, 2014). Another, earlier, report back in 2009, out of all the arrest made on P2P users, 33 percent of those arrested had images of children three years old and younger and 42 percent had images of children showing some type of sexual explicit material. (Pulido, 2013). Virtue Ethics is â€Å"A persons character is the totality of his character traits. Our character traits can be good, bad or somewhere in between. They can be admirable or not. The admirable character traits, the marks of perfection in character, are called virtues, their opposites are vices.†(Garrett, 2005)., I believe that this theory is a big part of someone who is willing to put everything at risk for something so degrading and disrespectful to themselves. A persons character says a lot about who that person is and what that person may be capable of doing. Not everyone has good virtue ethics and this is when one’s character and moral traits come in play. One’s character is shown through their actions an d behavior, whether this is being good or bad. One’s moral values are shown through their honesty, their loyalty, and their respect for others. As we all know pornography is very popular but it can also cause serious problems. Many people look at the disturbing images not thinking about the consequences, they are only thinking about what is happening at that moment and at that moment that’s what they want to do. I look at this issue using the deontology theory. â€Å"Rather than looking at the consequences of an act, deontology looks at the reason for which an act is done, and the rule according to which one chooses to act.† (Mosser, 2013). I take that as someone doing something on impulse rather than thinking about the consequences that they will face when they act upon their decision. If someone knew that they was going to destroy their marriage by watching porn, if someone knew that by watching porn it would make them fall behind on their bills, or  if someone knew that by watching porn they would go out and commit sexual crimes, do you think they would have continued or even started looking at these image s, I think not!

Symbolism in ?Young Goodman Brown? Essay -- essays research papers

â€Å"Young Goodman Brown,† by Nathanial Hawthorne, is the story of one man’s journey to find himself. In it, Hawthorne uses many elements as symbols to add significance throughout the chronicle. The author does a good job of portraying some of the people and objects with symbols and allows the story to become more developed. Nathaniel Hawthorne uses many people as symbols throughout "Young Goodman Brown," but the roles that are most symbolic are those of Goodman Brown and his wife Faith. Both of the characters' names are symbolic of their personalities. Goodman is truly a â€Å"good man.† Goodman Brown states, â€Å"With Heaven above and Faith below, I will stand firm against the devil† (322). This shows that he is a good religious man with a lot of faith in God....

Business Intelligence and Data Warehousing as a Solution Essay

As it is anticipated that there is a fundamental objective of the company to reduce costs, make informed decisions and consolidate information, there is urgent need to for resilient development of the business intelligence and data warehousing (Collier, 2012). The poor response by IT in the provision of strategic information indicates that the system is incapable of guiding the company to success. This is a potential threat to the prosperity of the business, and hence a quicker intervention is required to ensure success is attained. Business Intelligence and Data Warehousing as a Solution The implementation of BI and DWH services in the sales department would ensure a sustained growth and a competitive edge to the company. Integration of business intelligence would cover the use of information necessary to drive the organization insight. Operational business intelligence would produce an improved analysis of sales data and provide in-depth knowledge of the performance indicators of the marketing department such as the customers of the company, competitors, economic environment and internal operations that would in turn help in making efficient and best quality sales and marketing decisions (Collier, 2012). Also, the concept of data warehousing would enable a central integration and management of sales and marketing database containing data from the four operational sources in the department from heterogeneous sources. The created database would contain structured sales data for query analysis and can be accessed by all the authorized users. The good news reads that th e data warehouse can be created and updated at any time, with limited disruption of the operational systems (Simon, 2014). There is a broad set of technologies, applications and knowledge for gathering and analyzing sales data for the purpose of helping users make sales and marketing decisions. Issues Needed to be Addressed There is need to integrate BI and DWH applications in the operational systems as there is a significant requirement of current data for the purposes of sales. These tools are critical in supporting the sales and marketing decision makers in the organization. However, without proper governance, it would a long-awaited dream to achieve the value offered by BI and DWH. As such, there is urgent need to develop BI/DWH governance framework in the sales and marketing department based on universal principles and clear information ownership and dissemination. Essentially, there is a need for designing, implementing and making effective use of BI tools to achieve marketing objectives and increase revenue returns. Summary Making the most of the company’s data assets is the purpose of BI at a high level. The company would increase its competitive advantage such as reducing costs, increasing investment returns, reducing risks by making best data-driven decisions through a structured BI. Therefore, we can begin by developing the governance framework through designing, executing, monitoring and controlling and implementing to enhance proper management of the company sales data.

Mobilization for War Essay

Herman Goering thought that no Air force or military in the world could stand up to that of the Nazi Luftwaffe. His boastful statement was made with well acclaim in that the Luftwaffe was a very powerful aerial force, but he was being narrow-minded when he made this statement against the production potential of the United States, which has time and time again has proved to be the most powerful nation in the world. Without the military production of the United States, the Allies would not have had a chance against the Germans and their powerful forces. Through many changes, the labor and production force of the U.S. changed from producing civilian goods, to producing military goods. These goods were supplied to all nations of the Allied Powers, and the United States quickly became the most important factor in World War II. Starting in 1940, President Franklin D. Roosevelt promised to help the United Kingdom fight Nazi Germany by providing them with military supplies, but while staying out of actual combat. Roosevelt gave a radio broadcast on December 29, 1940, to address Americans to support the Allies in Europe and China, in their war against Germany and Japan. He called the nation an â€Å"Arsenal of Democracy† to  reference the powerful industrial machine it is, and how it can be the supplier of military goods to the Allied war effort. The United States military forces and most allied forces relied on the United States production of food and military goods. This meant that Americans on the home-front had to be rationed for what they can have, which meant they can only purchase so much of certain items. Many consumer goods had to be severely rationed or taken out of the market totally, because they were needed for the war effort. This is why Americans were encouraged to grow â€Å"Victory Gardens† so that they produced their own food, and what food they normally consumed from markets could help contribute to our troops as well as those of the Allied forces. Food production was then focused on providing for the troops instead of the everyday consumer, because they were expected to contribute for themselves and thus help contribute to the soldiers. The United States also made many technological innovations that helped revolutionize certain aspects of war, one of these being the pressurized air cabin in air planes. This helped prevent pilots from getting hypoxia (low oxygen levels in the blood), while also letting planes fly higher, and with more comfort for its passengers. This meant allied bombers like the b-29 could fly higher and escape low anti air missiles and fire from the ground. The Manhattan Project that the U.S. held with the United Kingdom and Canada also helped produce many technological innovations. The main product of this research program was the atomic bomb that would eventually be ordered into use on Japan, and would usher in their surrender and the end of the Second World War. We all know now that Goering’s statement was terribly misinformed, otherwise Germany and the Axis Powers would not have been defeated by the Allies. The United States was the team Captain in this effort and without them the chances of winning would have been slim to none. In the case of this war, and in the case of any war, production plays a key role, and in World War Two, the United States â€Å"Arsenal of Democracy† provided the Allies with the goods and resources necessary for victory.

Siege of Veracruz in the Mexican-American War

Siege of Veracruz in the Mexican-American War The Siege of Veracruz began on March 9 and ended on March 29, 1847, and was fought during the Mexican-American War (1846-1848). With the beginning of the conflict in May 1846, American forces under Major General Zachary Taylor won quick victories at the Battles of Palo Alto and Resaca de la Palma before advancing to the fortress city of Monterrey. Attacking in September 1846, Taylor captured the city after a bloody battle. In the wake of the fighting, he angered President James K. Polk when he granted the Mexicans an eight-week armistice and allowed Monterreys defeated garrison to go free.   With Taylor at Monterrey, discussions began in Washington regarding future American strategy. It was decided that a strike directly at the Mexican capital at Mexico City would be the key to winning the war. As a 500-mile march from Monterrey over rugged terrain was deemed impractical, the decision was made to land on the coast near Veracruz and march inland. This decision made, Polk was forced to decide on a commander for the mission. A New Commander While Taylor was popular, he was an outspoken Whig who had frequently criticized Polk publicly. Polk, a Democrat, would have preferred one of his own, but lacking an appropriate candidate, selected Major General Winfield Scott who, though a Whig, posed less of a political threat.  To create Scotts invasion force, the bulk of Taylors veteran troops were ordered to the coast. Left south of Monterrey with a small army, Taylor successfully held off a much larger Mexican force at the Battle of Buena Vista in February 1847. The sitting General-in-Chief of the US Army, Scott was a more talented general than Taylor and had come to prominence during the War of 1812. In that conflict, he had proven one of the few able field commanders and earned praise for his performances at Chippawa and Lundys Lane. Scott continued to rise after the war, holding increasingly important posts and studying abroad, before being appointed general-in-chief in 1841. Organizing the Army On November 14, 1846, the US Navy captured the Mexican port of Tampico. Arriving at Lobos Island, fifty miles south of the city, on February 21, 1847, Scott found few of the 20,000 men he had been promised. Over the next several days, more men arrived and Scott came to command three divisions led by Brigadier Generals William Worth and David Twiggs, and Major General Robert Patterson. While the first two divisions were comprised of US Army regulars, Pattersons was made up of volunteer units drawn from Pennsylvania, New York, Illinois, Tennessee, and South Carolina. The armys infantry was supported by three regiments of dragoons under Colonel William Harney and multiple artillery units. By March 2, Scott had around 10,000 men and his transports began moving south protected by Commodore David Connors Home Squadron. Three days later, the lead ships arrived south of Veracruz and anchors off Anton Lizardo. Boarding the steamer Secretary on March 7, Connor and Scott reconnoitered the citys massive defenses. Armies Commanders: United States Major General Winfield Scott10,000 men Mexico Brigadier General Juan Morales3,360 men Americas First D-Day Considered the most heavily fortified city in the Western Hemisphere, Veracruz was walled and guarded by Forts Santiago and Concepcià ³n. In addition, the harbor was protected by the famed Fort San Juan de Ulà ºa which possessed 128 guns. Wishing to avoid the citys guns, Scott decided to land southeast of the city at Mocambo Bays Collado Beach. Moving into position, American forces prepared to go ashore on March 9. Covered by the guns of Connors ships, Worths men began moving towards the beach around 1:00 PM in specially designed surf boats. The only Mexican troops present were a small body of lancers which were driven off by naval gunfire. Racing ahead, Worth was the first American ashore and was quickly followed another 5,500 men. Facing no opposition, Scott landed the remainder of his army and began moving to invest the city. Investing Veracruz Sent north from the beachhead, Brigadier General Gideon Pillows brigade of Pattersons division defeated a force of Mexican cavalry at Malibrn. This severed the road to Alvarado and cut off the citys supply of fresh water. Pattersons other brigades, led by Brigadier Generals John Quitman and James Shields aided in holding off the enemy as Scotts men moved to surround Veracruz. The investment of the city was completed within three days and saw the Americans establish a line running from Playa Vergara south to Collado. Reducing the City Within the city, Brigadier General Juan Morales possessed 3,360 men as well as another 1,030 offshore at San Juan de Ulà ºa. Outnumbered, he hoped to hold the city until aid could arrive from the interior or the approaching yellow fever season began to reduce Scotts army. Though several of Scotts senior commanders wished to attempt a storming of the city, the methodical general insisted on reducing the city through siege tactics to avoid needless casualties. He insisted that the operation should cost the lives of no more than 100 men. Though a storm delayed the arrival of his siege guns, Scotts engineers including Captains Robert E. Lee and Joseph Johnston, as well as Lieutenant George McClellan began working to site gun emplacements and enhance the siege lines. On March 21, Commodore Matthew Perry arrived to relieve Connor. Perry offered six naval guns and their crews which Scott accepted. These were quickly emplaced by Lee. The next day, Scott demanded that Morales surrender the city. When this was refused, the American guns began bombarding the city. Though the defenders returned fire, they caused few injuries. No Relief The bombardment from Scotts lines was supported by Perrys ships offshore. On March 24, a Mexican soldier was captured carrying dispatches stating that General Antonio Là ³pez de Santa Anna was approaching the city with a relief force. Harneys dragoons were dispatched to investigate and located a force of around 2,000 Mexicans. To meet this threat, Scott dispatched Patterson with a force which drove off the enemy. The next day, the Mexicans in Veracruz requested a ceasefire and asked that women and children be allowed to leave the city. This was refused by Scott who believed it to be a delaying tactic. Resuming the bombardment, the artillery fire caused several fires in the city. On the night of March 25/26, Morales called a council of war. During the meeting, his officers recommended that he surrender the city. Morales was unwilling to do so and resigned leaving General Josà © Juan Landero to assume command. On March 26, the Mexicans again requested a ceasefire and Scott sent Worth to investigate. Returning with a note, Worth stated that he believed the Mexicans were stalling and offered to lead his division against the city. Scott declined and based on the language in the note, began surrender negotiations. After three days of talks, Morales agreed to surrender the city and San Juan de Ulà ºa. Aftermath Achieving his goal, Scott only lost 13 killed and 54 wounded in capturing the city. Mexican losses are less clear and were approximately 350-400 soldiers killed, as well as 100-600 civilians. Though initially chastised in the foreign press for the inhumanity of the bombardment, Scotts achievement in capturing a heavily fortified city with minimal losses was staggering. Establishing a large base at Veracruz, Scott quickly moved to get the bulk of his army away from the coast before yellow fever season. Leaving a small garrison to hold the city, the army departed on April 8 for Jalapa and began the campaign that would ultimately capture Mexico City.

Many Types of Drop-In Fuels

Many Types of Drop-In Fuels These days, it’s hard to find an organic material that isn’t being positioned as the next great alternative energy source. Rising to the top of the list are biofuels known as so-called â€Å"drop in† fuels – those renewable sources that can be used without major investment in infrastructure in the U.S. where storage and distribution has long catered to petroleum. That current investment in infrastructure isn’t small potatoes. There is about $7 billion in pipeline expenditures alone each and every year. Defining Drop-in Fuels What defines a drop-in fuel? The alternative fuels industry itself isn’t exactly clear, with some defining it broadly to mean any renewable fuel making use of at least some of the costly existing petroleum infrastructure. Others have taken a more narrowed approach. One of the most popular definitions is that drop-in fuels are those renewable fuels which can be blended with petroleum products, such as gasoline, and utilized in the current infrastructure of pumps, pipelines and other existing equipment.    Under such a definition, a biofuel would require some percentage of gasoline blender , derived from unique gasoline stocks, to form the fuel’s base. Examples of drop-in fuels defined in this way include the terpenes, butanol and isoprene, among other. Often, the technology is applied to diesel fuel, forming a biodiesel, rather than to gasoline. There are even some next-generation biofuels proponents who are developing mixtures of chemicals to form a biofuel without the gasoline or diesel base. Algae Most Common Drop-in Fuel With well over 50 companies investing in the development of algae as a biofuel, the little green plant reigns supreme among drop-in fuels. Yet, despite this general interest, most biofuels experts agree that at least another decade of research and technological breakthroughs will be necessary before this drop-in fuel is deemed commercially viable. That’s a long- and costly- trail ahead. As with most drop-in fuels, the challenges come in moving the technology from the lab to full-scale commercial production. An additional challenge with algae specifically has been the wide variance among algae and the extensive processing necessary. Butanol Also Sees Growth But algae isn’t the only show in town. Last year, a leading biobutanol company, Gevo, announced plans to acquire ethanol facilities in the Midwest and convert them to commercial production of the drop-in fuel isobutanol, also known as isobutyl alcohol.    The move was seen by industry players as a step forward in the development of butanol as an alternative drop-in fuel, with the company hoping to begin isobutanol production by 2012. Although able to make use of existing infrastructure, unlike algae, there is some concern over potential safety threats. Vapors can travel long distances and collect in low-lying areas to form an explosion hazard. However, its proponents are quick to point out the biofuel’s many fuel and chemical applications make it an attractive venture. Big player DuPont has also tested the waters of biobutanol as a drop-in fuel and plans to likewise rely on existing under-utilized ethanol capacity and conventional feedstocks as it gets its operations off the ground. The investment to retrofit existing ethanol facilities is more economical than building new structures and require only minor changes to the fermentation and distillation processes. Broadening Portfolios DuPont says it plans to follow a multi-step approach to drop-in fuel development, first focusing on n-butyl alcohol and conventional feedstocks before moving on to other drop-in fuels like isobutanol as well as non-feed crops, such as cellulosic feedstocks.    Yet another company, ButylFuel, LLC, has gone on record as having said it has now developed fermentation-derived biobutanol at a cost that is competitive with petroleum products. Its drop-in fuel can be blended at a variety of percentages with gasoline or diesel fuels. How competitive? The company claims it can produce its drop-in fuel from corn for about $1.20 per gallon. Like algae players who are benefiting not only from algae as a drop-in fuel, but from the many byproducts as well, research and development in other drop-in fuels sectors are looking at diverse portfolios of products, causing some to characterize this next generation of alternative fuels as a means to produce hydrocarbon blend stock that can have a multitude of applications.

Refection paper - Essay Example The speaker based her presentation on life experience and the entire event was informative and identified concepts that are applicable to my real life situation (Syracuse University). The event was informative and improved my knowledge on existence of challenges from different aspects of life. It also enlightened me on different aspects of life and their roles in facilitating strength and coexistence among individuals. With the knowledge of natural and human imposed limits, the event taught me of the benefits of courage in facing challenges. A courageous heart will for example have strength to embrace difficulties and uncertainties until success is realized and therefore reduces chances of missed opportunities. The event has also taught me the concept of persistence and determination in pursuing a venture. These concepts define continued efforts in spite of possible challenges in a situation and they eliminate possibilities of losing a viable opportunity because of lost hope from frustrations. Close to the concept of persistence is the concept of perseverance that I also learnt from the unit and that facilitates success in initiatives (Syracuse University). I also learnt of the importance and significance of having a purpose in an individual’s life, of having a driving factor in a person’s life, of being spiritual and being able to maintain established potentials. A purpose establishes targets to be attained and facilitates development of strategies for attaining those targets. I have also learnt to understand purpose as an intrinsic motivator that encourages efforts towards achieving desired goals. The event also enlightened me of the need to be a motivated person in order to embrace and even overcome challenges in life. Hope, courage, and faith that are developed from spiritual aspects of life are other sources of power and strength towards managing challenges and overcoming them to achieve success (Syracuse University).
