Common Rail Direct Injection Essay Example for Free

Common Rail Direct Injection Essay Direct injection means injecting the fuel directly into the cylinder instead of premixing it with air in separate intake ports. That allows for controlling combustion and emissions more precisely, but demands advanced engine management technologies. Unlike petrol engines, diesel engines don’t need ignition system. Due to the inherent property of diesel, combustion will be automatically effective under a certain pressure and temperature combination during the compression phase of Otto cycle. Normally this requires a high compression ratio around 22 : 1 for normally aspirated engines. A strong thus heavy block and head is required to cope with the pressure. Therefore diesel engines are always much heavier than petrol equivalent. The lack of ignition system simplifies repair and maintenance, the absence of throttle also help. The output of a diesel engine is controlled simply by the amount of fuel injected. This makes the injection system very decisive to fuel economy. Even without direct injection, diesel inherently delivers superior fuel economy because of leaner mixture of fuel and air. Unlike petrol, it can combust under very lean mixture. This inevitably reduces power output but under light load or partial load where power is not much an important consideration, its superior fuel economy shines. Another explanation for the inferior power output is the extra high compression ratio. On one hand the high pressure and the heavy pistons prevent it from revving as high as petrol engine (most diesel engine deliver peak power at lower than 4500 rpm. ), on the other hand the long stroke dimension required by high compression ratio favors torque instead of power. This is why diesel engines always low on power but strong on torque. To solve this problem, diesel makers prefer to add turbocharger. It is a device to input extra air into the cylinder while intake to boost up the power output of the engine. Turbocharger’s top end power suits the torque curve of diesel very much, unlike petrol. Therefore turbocharged diesel engines output similar power to a petrol engine with similar capacity, while delivering superior low end torque and fuel economy.

New Grub Street as a Microcosm of English Victorian Life Essay

  Ã‚   New Grub Street presents the reader with an accurate and comprehensive picture of late Victorian society, despite the fact that it predominantly focuses only on a small group of literary men and women. At first, one may have difficulty locating Gissing's voice within the narrative. The perspective leaps from character to character, without establishing any clear candidates for the reader's sympathies. Jasper Milvain is ambivalently portrayed, despite the fact that his moral and literary values were anathematic to Gissing. This is but one example of ambiguity in a novel that is filled with confusion and inversions of the 'natural order'. The world of New Grub Street is one where the unscrupulous Jasper Milvain triumphs, the mediocre Whelpdale stumbles upon commercial success, while others such as Edwin Reardon, Alfred Yule, and Harold Biffen undisputedly become casualties in the battle of life. What is Gissing trying to say about Victorian England? (Or is literary life his so le intended subject?) Throughout this chaos of view-points are interwoven the themes of money, class, and sex. Yet it is precisely the ubiquity of these themes, and the prevalent disorder of the world that makes the novel reflective of late Victorian society. Whether or not Gissing intended his novel to be purely a study in the changing literary life of the late nineteenth century, New Grub Street is effectively a microcosm of English life in the closing years of Victoria's reign.    New Grub Street depicts some of the consequences of the structural and compositional changes that were - and had been - taking place in the social and class structures of Victorian England. The increasing size of the middle class1, the reductions in working hours2, an... ...

Business Plan Analysis – Private Concepts

Memorandum Re: Business Plan Assessment – Private Concepts Critically analyzing a business plan for its viability and opportunity for success is absolutely necessary from any stakeholder’s perspective. Doing so aides an investor in knowing whether or not to invest, a bank in deciding on a loan, or even a partner in his/her decision to join a venture.But perhaps most importantly, a critical analysis of a business plan can and will help the entrepreneur to assess whether or not an idea under its current platform is worth undertaking, or if it is back to the drawing board they go. The purpose of this memo is to assess the business plan of Private Concepts, a company hoping to bring to market The Pevlon, a cervical cancer screening device made for private, in-home use. The opportunity for such a device absolutely exists both here in the United States and abroad.For one, the plan mentions The Breast and Cervical Cancer Mortality Act of 1990 which, â€Å"mandated a nationwid e program to increase access of medically underserved women to comprehensive breast and cervical cancer screening services,† and when coupled with the Patient Protection and Affordable Care Act that was recently passed, the amount of free (to consumer; paid for by the government) access to this product creates potential for a high demand in this country.In foreign countries however, such as rural China and even Africa, where access to healthcare and proper healthcare facilities can be extremely rare, the appetite for this type of product could be tremendously significant. And there lies the first issue with this business plan. According to the Lancet Oncology medical journal, Volume 11, Issue 12, â€Å"75,000 women develop cervical cancer and 40,000 women die from the disease in China each year. † Those numbers in the United States are only about 12,000 and close to 4,000 respectively (cdc. ov). This exemplifies a larger need for this product abroad as opposed to right here in the states. And to focus on the opportunity in China, a Wall Street Journal publication explains how China’s healthcare system is lacking in general, but puts a microscope on the disparity in quality healthcare between rural and urban areas (Burkitt, 2012). These rural areas in China represent a large opportunity (much larger than any market in the United States) for The Pevlon.And so although the opportunity does exist for the business plan’s product, it is evident that the opportunity accentuated in the business plan is not the optimal one (aside from appealing to non-profits or other entities that would utilize the Pevlon in charitable, undoubtedly foreign ventures – this should have been a more significant portion of the plan). Additionally, the opportunity in the United States has not necessarily been proven to the point where one could consider the need for the product as pervasive enough to where the consumer is willing to pay for it.And pay for t hey would have to, because as the plan notes in the chart on page 10, a Pevlon screen costs 50% more than a typical pap smear. This exemplifies that pricing is going to be an issue. The health care market is highly dependent on the insurance industry, especially when there are product substitutes. Take pharmaceuticals for example. In group health care, policies are dictated by the contract that is in place and the majority of these contracts will sway the policy holder to utilize generic medications.This is done by the insurance carrier covering a larger percentage of generic medications than name brand ones, which ultimately costs the carrier less. So if a pap smear is less costly by 50% than a Pevlon test, carriers may still cover the device, but the â€Å"incentive† to utilize the cheaper procedure will absolutely be in place. Additionally, the business plan identifies lower income women as a target market, but fails to explain how a more expensive procedure will be a viab le option for this segment group. But even when the entire U. S. arket (via a sample size) is observed on page 19 of the plan, less than half of the women surveyed (46%) stated they would utilize the in-home Pevlon test even if most or all of it was covered by insurance. And if insurance reimbursement is removed completely, only 11. 2% of women would purchase the product. It would be interesting to see if there were follow up inquiries related to this line of questioning because a hypothesis is that some women, or maybe even a lot of women, may not trust themselves to complete such an important test at home.These women may simply prefer to rely on the expertise of a medical professional. And along these same lines, I feel as though the plan is silent on a very important aspect when it comes to assessing the true market of this product: how many women are in fact uncomfortable with going to a physician’s office to have a pap smear completed and would those women be more comfor table completing such a screen at home?Yes, there is a quote stating how uncomfortable the procedure is (which is in fact the first thing the reader sees underneath the Executive Summary heading), but it is somewhat suspect that this quote is anonymous and that there is no quantifiable evidence proving this notion to be true. So what is the actual desirability of this product? There really is no proof of it within the business plan and if I was investing in this product, I would need this â€Å"proof. † Aside from the ambiguous desirability of the product, there are a number of other concerns that should really stick out to the potential investor.On page 12 of the business plan there is a section that lays out the testing and approval stage for the Pevlon device. There are 6 steps in this section and only 1 of which have been completed, which happens to be the least significant of steps. The remaining rigmarole of securing FDA approval, obtaining the green light to conduct cl inical studies, actually conducting these studies, etc. could easily take upwards of a decade to complete. From the perspective of an investor or a bank assessing a loan, this is entirely too long a process for someone to simply START making their money back.This exemplifies how difficult a market healthcare can be to get into, and that the barriers involved are simply too high. Additionally, the Pevlon is not necessarily a onetime revenue generator, but it comes uncomfortably close. In 2009, the American College of Obstetricians and Gynecologists (ACOG) released new cancer screening guidelines. According to ACOG, women now need to begin screening at age 21 as opposed to 18, and women ages 21 to 30 only need to be screened once every two years; women 30 and older only once every 3 years (Cox, 2009).The final qualms that I have concerning this business plan is the window of opportunity associated with the product, and the amount of time it will take for Private Concepts to become a p rofitable company. There does not appear to be an actual window of opportunity as the business plan does not thoroughly prove the market segment. Anecdotally I polled a number of women in my life with whom I am comfortable bringing this subject up and all of them (4) took the opinion that their screenings are not a major source of stress or discomfort, but rather they have come to accept it as â€Å"part of the routine of life. And in regards to becoming a profit generating entity, right up front on page 3 of the business plan, it is shown in the chart that Private Concepts would not be in the black until 5 years of doing business. What’s most concerning is that 5 years is still merely a hypothesis and that the organization is seeking over three million dollars in funding basically right out of the gate. Conceptually, the idea of a self administered, in home cervical cancer screening is a good idea.It poses benefits such as convenience and avoiding uncomfortable screenings a t a physician’s office. Private Concepts missed the mark in their business plan however, in a number of ways. The market was identified too ambiguously and the plan did not clearly exemplify certain key aspects of said market such as how many women actually would prefer an in home screen versus one performed in a physician’s office. Where to market and focus sales efforts was clearly stated, however, the idea to sell first in the United States is not the best possible plan of action.Private Concepts should as the plan mentions, manufacture the product off shore in order to maximize profit margins, but at the same time the pricing point should be rethought considerably in order to capitalize on the more fruitful markets of places like rural China and Africa. Appealing to non-profits and government entities that might focus on these foreign demographics was a small piece of the business plan, but it should have been more of a focus.Finally, in this assessment I had the a dvantage of hind sight and context. This business plan won the Moot Corp competition in 2002 with what appeared to be a viable business plan at the time. This product has yet to come to market and I was unable to find anything stating that the Pevlon has been approved by the FDA. This does not necessarily hold any bearing on this analysis of the business plan; however, it does prove to a certain extent, a lot of the shortcomings that were found within this business plan.Academically and structurally the plan was very well done, however in practical application it is easy to see how and why the Pevlon is still an unknown product to virtually the entirety of the woman population in the United States.

Hale s letter to Danforth corrected

Your Honor, Abigail Williams is nothing but a where who wants to dance with John Proctor, an extremely moral man who had dedicated his life to God, on his wife's grave. The lies that Abigail Williams has cooked up is punishment for John Proctor for taking away her innocence. She is nothing but a where who lusts for John Proctor. Vengeance is running through Salem, Your Honor, and people who have been falsely accused will die; you will have their blood on their hands, Judge Detonator. Will you be able to sleep at night knowing you signed the death warrants of innocent people? Your gavel ill be stained blood-red.Can you live with your conscience? Your Excellency, the cries of witchcraft are the same cries as a whore's vengeance fuelled by lust. People with names whiter than white within the community of Salem are having their good name soiled and blackened. Believe that if more people are accused by whore's like Abigail Williams and you continue to devour their lies, your soul will bec ome blackened and guilt-ridden. Judge Detonator, permit me to proceed, ninety-one people have signed a testament saying that Elizabeth, Martha, and Rebecca are good respected Christian women who loud never compact with Lucifer.Should ninety-one people lie? Think not. You cannot ignore the people of Salem any longer. You cannot ignore their good opinion or soon there will be no-one left in Salem who you think is somehow is working for the devil. The people of Salem must have known this woman all their lives; if they had compacted with Lucifer, would they have concealed it from their closest friends? If the devil had been working here, why has there not been any sign of the Devil before. You believe the lies Abigail Williams is feeding you with seemingly no care for the normal people f Salem.Is there another reason why you are not taking the testament of the god-fearing people of Salem? Seriously? I've noticed you sweat like a stallion whenever Abigail Williams is near. She is manipul ative , Judge Detonator and you must not fall in her trap. Will you take the words of one child, who is intoxicated by power, over the opinions of ninety-one upstanding members of the community? The ball is now in your court, Judge Detonator. The blood of these respected Christian women will be on your hands, Your Honor. Furthermore, after witnessing Mr..Jacobs' testimony in court, it became parent that this trial was never about witchcraft in the first place. This trial is a tale about greed and power, a soulless tale about people who want things that are not theirs. How can a man who can barely stand on his own two feet be accused of terrorizing Ruth Putnam? I would think that if he was under the impression of Lucifer, he would use the power to be able to stand up without any support. Mr.. Putnam is a parasite; sucking the blood out of innocent people for his own fat belly. Rut's accusations must be dealt with separately and with great care, Your Honor.Giles Corey swears to a depo sition that Putnam forced Ruth to cry witchcraft in an attempt for more land. Corey had been in court more than twenty times, winning every case, Your Honor. Surely, you can emphasize and draw the conclusion that Corey is reliable and trustworthy and that his deposition must be considered with great thoughts and wisdom. Plead with you to look at the evidence again. If you want the blood of Mr.. Jacobs on your hands, you should listen to the lies that Ruth Putnam is feeding you instigated by her father, the very greedy Mr.. Putnam.How could you not believe the words of John Proctor? Why the man with the rest name in Salem throw away his good name after claiming to be an adulterer? It is in my good opinion that Abigail Williams seeks vengeance on John Proctor for taking her innocence. Elizabeth lied to protect her husband, just like any women would lie to protect her family life, children and husband. Even someone like Goody Proctor, who has never told a lie before. This is a natural lie to tell. I beg of you, your Honor, to reconsider your decision on sending Elizabeth to the jailhouse. You must ensure that this trial is fair.Telling Proctor and Abigail to stand with their backs facing Elizabeth was not a air way to question her. You are a noble judge. We saw John Proctor break down in court and this is not the behavior of a man who is trying to deceive or undermine the court or the trial. Your Excellency, Proctor is a well-respected farmer and his wife has no mark upon her name. They are good souls who don't deserve to be hanged due to the lies of Abigail Williams and the girls. Abigail is hell-bent on seeking vengeance on Proctor. Abigail is comparable to Lucifer. She pulled the wool over your eyes , the girls and even me at the beginning.But I saw this presence and soon will you. She has deceived most people in the village including you. Can see she has played you like a violin and Your Honor , it seems you cannot hear enough of this wretched symphony. Beg o f you, see through the evil surroundings of Abigail Williams. F you kill these innocent souls, your hands will be stained blood-red. The blood of the innocent people you have killed. Your gavel , the paper you sign , the table and your soul will be stained with blood. In addition, the women we have already convicted of witchcraft are of the lowest status in Salem: a lunatic and a beggar.As the local beggar, there is not only one person in Salem who Goody Osborne has not annoyed with her requests for bread and cider. I can imagine there are a lot of people happy to see her locked up. But, consider Your Honor, does being poor equate to being a witch? Surely Lucifer would find it too easy to win the soul of a beggar! If Lucifer had taken Goody Osborne soul, why is she still poor? She is not such a fool to part with her soul for anything less than abundant money. Sarah Good, the local lunatic is in the same position- surely you see this? The local people are afraid of her trance mumblin gs and behavior.It is easy to cry witch on someone who is not in sound enough mind to defend herself. Judge Detonator, I humbly ask you to think more on these two individuals, there really is no sufficient evidence to send them to the jailhouse as they are just poor unfortunate souls. Finally, Sir, it's in my good Opinion that the accused are good people with pure souls. They are innocent and they have been caught up in a web of lies, Judge Detonator. You know as well as do that Abigail Williams and Thomas Putnam are not reliable enough to cause the deaths of innocent people.

CV Writing Makeover †A Holy Grail for Older Job Seekers Essay Example

CV Writing Makeover – A Holy Grail for Older Job Seekers Essay Example CV Writing Makeover – A Holy Grail for Older Job Seekers Essay CV Writing Makeover – A Holy Grail for Older Job Seekers Essay Seeking the right job or availing the right opportunity seems pretty difficult to older job seekers. Our economy is another critical factor behind the difficulties experienced by older individuals. It is a pretty common thing in today’s economy for people at older age to retire from the job they have been doing for a very long time. It is also not unusual to see our senior citizens looking for a second career or job, since they want to keep working even after getting retired. However, competing with the younger job seekers and outperforming them to secure the right job is no easy task at all. How amazing it would be if potential recruiters wouldn’t reject the job applicants only due to their older age. But let’s face the truth here. In our current era, employers prefer younger applicants than older individuals. In other words, in the present era youthfulness usually surpasses experience. Nonetheless, don’t let despair get the best of you as there are some effective ways to outshine the younger generation and get the right employment. First it would be great if you don’t mention your age in your resume/CV. This will allow you to have a better opportunity to get to the interview room. However, if you are in a situation where mentioning your age is necessary then it would be wise to highlight your qualities, skills and experience to overcome the age barrier. Be confident and be proud because you know that you are dependable, trustworthy, hardworking and experienced. You only need to show these qualities to the potential employer to get the job. Believe in yourself if you are sure that you have what it takes to be the best in your field. Apparently, many older job seekers are retired but they still want to keep working. However, during the course of their employment search, they encounter other candidates younger than them. In addition to that they also experience that many potential employers don’t give much response to their job application. This individual treatment brings out anxiety in the older job seekers, thus making their job search experience quite stressful. What must I do to overcome this anxiety and secure a good job? Well, you need a CV makeover to achieve that goal. The most important thing you need to do is to update your old CV. Remember that the main source of your misery is an outdated CV. Therefore, give it a makeover to make it more prominent. Incorporate the latest trends in your application/CV/cover letter. Determine latest necessary technological skills that you lack and need to develop. For instance many employers require computer-literate people who at least know how to use documents and spreadsheets. Work on these skills to ensure your job. Use powerful keywords in your CV to increase its expose on the online job hunt platforms.

How to realistically fill your resume when you have no experience

How to realistically fill your resume when you have no experience You need to have a job to gain experience, but you need experience to get a job. At the beginning, just about everyone faces this catch-22. Even jobs that seem like entry-level gigs require a resume as part of your application, so how do you craft your resume to make sure you’re presenting a solid, â€Å"hire me† package even if you don’t have experience yet? Pick a friendlier formatThe good news is that resumes have gotten more flexible over time. It used to be that everyone submitted pretty much the same resume: header + objective + reverse-chronological job history + skills + extras. Now, employers are used to seeing a variety of formats. For job hunters who are forging into a new field or just starting out, it makes more sense to play up your skills- not necessarily your experience. For that, you want a resume that prioritizes your skills and know-how.For example, your resume might break down like this:HeaderObjective/Summary StatementBulleted list of skills, targeted specifically to this job descriptionEducation/CertificationsWork ExperienceThe whole point of your resume isn’t to create some arbitrary cookie cutter version of yourself, it’s to show yourself off in the best possible light. So don’t be afraid to switch up the sections if it means you’re creating a stronger narrative about who you are as an employee.Your resume should build a narrative about you that’s clear to anyone reading it, so you want to put your highlights reel first. Start with a clear statement about who you are and what you’re seeking, then emphasize the skills and strengths that you bring to the job. You should still include a work experience section even if it feels a little sparse, but you can tuck it at the end after you’ve played up your strong points.Realize you have more experience than you think you doYou may not have full-on work experience yet, at least not in the field for which you’re applying. But chances are, you do have some kind of experience, and have built skills along the way. If you’re a student (or a recent grad), think about courses you’ve taken that are relevant to this job or company. This doesn’t mean you should list every class you ever took just to take up space. Think strategically, and pick courses that relate to the job for which you’re applying. Internships are even better, if you’ve got any of those under your belt, because that’s hands-on experience.And don’t forget extracurricular activities. Volunteer experience is often overlooked because people tend to assume that unpaid experience isn’t the same as job experience. Guess what? Volunteer experience is time spent building skills and relationships- both things that look fantastic on a resume. It may seem like your volunteer experience doesn’t necessarily align with the job you want, but you can finesse it. For example, say you volunteered at a kids’ community center but you’re applying for a marketing gig. Think about the tasks you did in your volunteer work. Did you arrange things (organizational skills)? Manage a schedule (time management)? Act as a liaison for people or groups (communication and teamwork)? Create programs or lead anything (leadership)? Take skills that employers value, like ability to work with others, leadership, organization, communication, and try to match up your volunteer experience with those skills.Resist the urge to exaggerate too muchThis is a case where â€Å"fake it ‘til you make it† is not going to help you. If you include skills and experience points that aren’t quite true, you’re running a significant risk of getting caught. Best case, no one questions your whale tales and it gets you the job. All is great until someone asks you to demonstrate the Spanish language fluency you listed on your resume or use that fancy Excel wizardry you claimed to have developed at your last job. Over-exaggerating isn’t really a way to compensate for a lack of experience, and if you’re called out on it, it will be very awkward (not to mention harmful to your prospects of getting the job).Consider certificationAnother way to make up for a lack of specific job experience is to get specific education or certification that prepares you for the job. Are there certifications in your field? Licensing organizations? By going through the process of becoming certified, you’re getting an outside party to say, â€Å"hey, this person is qualified.† And that’s something you can put near the top of your resume to show you’ve got the skills and training- if not years of experience.Remember: it’s all about emphasizing what you do have and framing your resume narrative in a way that shows you’re ready, willing, and able to take the job, no matter how much experience you have (or don’t have).

Economics Research Paper Example | Topics and Well Written Essays - 1000 words - 4

Economics - Research Paper Example Undeniably, information security has evolved to be as significant to contemporary organizations as the security of perceptible physical resources. It is not surprising that the quickly increasing body of research dwells on issues of information security. Research should focus largely on the technical dynamics of the protection of information in computer-based systems through encryption, hardware controls as well as software and data controls. The behavioral dynamics associated with the prevention breaches in information security have attracted a lot of attention in the recent times among researchers. Conversely, there has been very little attention towards addressing the economic aspects of information security; particularly with the magnitude of resources that have been directed to improve information management by organizations, what these organizations require is a framework that will assist in deriving optimal levels of spending on information security. Economic perspectives typi cally recognize that even though some degree of investment in information security is noble, additional security is not always worth the associated costs (Bidgoli, 2006). Therefore, it is important to consider the manner in which vulnerabilities of information as well as losses that are linked to the vulnerability impact the ideal amount of resources that are supposed to be directed to making information secure. For a wide variety of probability functions in regards to security breach, the ideal amount that should spent on information security is a rising function based in the degree of the vulnerability of the information. However, in some cases, the ideal amount to spend on security of information initially increases and later declines with similar degrees of vulnerability of information (Rao & Upadhyaya, 2009). The managers who are responsible for allocation of information security budgets should typically concentrate that is categorized in the mid-range of
