Minor members of the solar system free essay sample

Asteroids are small rocky bodies that have been likened to â€Å"flying mountains. † The largest, Ceres, is about 1000 kilometers in diameter, but most are only about 1 kilometer across. The smallest asteroids are assumed to be no larger than grains of sand. Most asteroids lie between the orbits of Mars and Jupiter. They have orbital periods of three to six years. Some asteroids have very eccentric orbits and travel very close to the sun, and a few larger ones regularly pass close to Earth and the moon. Many of the most recent impact craters on the moon and Earth were probably caused by collisions with asteroids. Many asteroids have irregular shapes. Because of this, planetary geologists first speculated that they might be fragments of a broken planet that once orbited between Mars and Jupiter. Others have hypothesized that several larger bodies once coexisted in close proximity, and their collisions produced numerous smaller ones.

COMETS Comets are the shining wanderers of the solar system. With their glowing tails that may stretch 100 million kilometers through space. Most comets reside in the outer fringes of the solar system, far beyond Pluto. For all their apparent size in the sky, comets are actually fairly small objects. When a comet begins its trip down past the Sun, it is probably a chunk of dirty ice, a mixture of rock dust and ice a few kilometers across, much smaller than the typical observed asteroid. As it speeds towards the Sun, the heat from the Sun evaporates the ice, and the gases thus released blow dust particles outward from the solid body or nucleus. Radiation from the Sun ionizes the released atoms, producing a tail that glows in the sky like a neon sign; the dust particles reflect sunlight and form another, smoother tail. But not all develop a tail that extends for millions of kilometers. The fact that the tail of a comet points away from the sun in a slightly curved manner led early astronomers to propose that the sun has a repulsive force that pushes the particles of the coma away, thus forming the tail. The tails seem white to the eye, but color photography reveals that the ionized gas tail is blue and the dust tail yellow. The small nucleus, the only even near-permanent part of a comet, is surrounded by the coma or head of the comet, a large, hazy structure formed by the liberated gas and dust. Of the 100 billion comets that may exist, less than 1000 have been observed thus far as they make the long journey down to the heat of the Sun. Halleys is one of the best-known and brightest comets others are the Oort cloud which are comets that appear to be distributed in all directions from the sun, forming a spherical shell around the solar system. METEOROIDS Often referred to as a â€Å"shooting star. † This streak of light occurs when a meteoroid enters the Earth’s atmosphere. A meteoroid is a small solid particle that travels through space. Most meteoroids originate from any one of the following three sources: (1) Interplanetary debris that was not gravitationally swept up by the planets during the formation of the solar system (2) Material from the asteroid belt, or (3) The solid remains of comets that once traveled near Earth’s orbit. A few meteoroids are believed to be fragments of the moon, or possibly Mars, that were ejected when an asteroid impacted these bodies. Some meteoroids are as large as asteroids. Most, however, are the size of sand grains. Consequently, they vaporize before reaching Earth’s surface. Those that do enter Earth’s atmosphere and burn up are called meteors. The light that we see is caused by friction between the particle and the air, which produces heat. Occasionally, meteor sightings can reach 60 or more per hour. These displays, called meteor showers, result when earth encounters a swarm of meteoroids traveling in the same direction and at nearly the same speed as Earth. A meteoroid that actually reaches Earth’s surface is called a meteorite.

10 Tips for Success with Outbound Marketing on LinkedIn

10 Tips for Success with Outbound Marketing on LinkedIn Outbound Marketing on LinkedIn – Tips from Dafna Rolls Ish of D|Rolls Associates Last week, you may have read about my adventures in Israel without a tour bus. One of the events I highlighted was my presentation to a standing-room-only audience at Google Campus Tel Aviv. The event included an enlightening talk by Dafna Rolls Ish-Shalom, CEO at D|Rolls Associates, about how to conduct outbound marketing on LinkedIn. What is Outbound Marketing? Outbound marketing on LinkedIn differs from inbound marketing. Inbound includes â€Å"making noise in a good way,† like publishing articles and participating actively in groups. In contrast, outbound marketing on LinkedIn entails understanding your target market and what types of people or companies you want to approach, and then creating a campaign to reach them. Dafna focused on B2B strategies, but many of her tips apply to job seekers as well. Regardless of your business or career situation, LinkedIn is an extremely strong tool for creating an initial connection – and you can use it to forge ongoing connections as well. As Dafna pointed out, while not everyone will connect, and not everyone who does will continue the conversation, either way you’re creating awareness. You’re starting a conversation- and that has value. Dafna’s Top Tips on How to Succeed with Your Outbound Marketing on LinkedIn Identify and research your target market. Who are they? If they are investors, what type of investor? If they are CTOs, what type of companies do they work for? Once you know who they are, find out what projects they’ve been involved with in the past. Read their profiles and find out who you know in common, including any mutual connections you have at their company. Personalize and customize your connection requests. Tips on how to do that are in my book, How to Write a KILLER LinkedIn Profile. How you approach a person depends on the audience. You’d write a different message to a client than you would to a potential investor or partner. With anyone, the initial contact should be short and sweet. Don’t overwhelm with detail. Provide additional information as the relationship develops.For your first message, you might say something like, â€Å"I see you are involved with XYZ company. I’d like to speak with you about x venture.† Perhaps mention a common connection or an article the person published. Show the person you know who they are and that you care. If they respond, don’t leave them hanging. Keep the conversation going. Even a day’s delay can lose the connection. Practice! Start your campaign with your B-level list first, and use the response you receive to understand the mind of the decision-makers who are your target. Don’t make beginners’ mistakes with your A-list! Use a CRM (Dafna recommended Hubspot). Track which campaigns are effective and which audiences respond best to your message. And to state the obvious, create and maintain a database and ensure it’s accurate and up-to-date. You’re only as good as your leads. Connect with your colleagues throughout your career. You never know when you will benefit from those connections! Also don’t be shy about asking for and providing introductions – and recommendations. Move the conversation from LinkedIn to the phone or even a video call. Whenever you talk to someone in a business context, call from a quiet place – professionalism is more important than calling back fast when there is noise around (this one I learned the hard way). Always smile – it changes the tone of your voice. And be prepared for small talk. Check the weather, sports, events wherever your client is. Those details truly make a difference. Look professional. If you’re calling from home in your pajamas, put on a scarf so no one knows you just got out of bed! My favorite trick is putting on a suit jacket over my yoga clothes. Be on the lookout for how you can meet someone’s needs. Even if someone calls to sell you something, you never know when you might turn that into business for you! Use trade shows and conferences as an opportunity to connect with your LinkedIn network. If you’re attending something, post on LinkedIn saying â€Å"I’ll be in Paris for the xx event, and would like to meet xx people†¦Ã¢â‚¬Å" Also join any specific LinkedIn groups that might exist for the trade show or conference. Optimize your profile and your company page. Your leads will check them! How to Write a KILLER LinkedIn Profile will teach you how to do that. Remember that optimizing your LinkedIn profile requires ongoing activity – publishing articles, posting to groups, and sharing updates and photos about your professional activities. Use hashtags to tag people and companies in images so that they are more likely to read your posts. And if you have a company page, use it! Share recommendations you receive from clients, as well as posting open positions in your company. While all of this might seem overwhelming, it’s essential that you set aside time every day to check your profile and work on lead generation. If that is not possible, don’t hesitate to use an experienced ghost writer who will do this for you with approved scripts and target lists. D|Rolls, based in Israel, has proven these strategies work. She has gotten meetings for top US food retailers for an Israeli company, set up meetings for CEOs during their travels, and landed qualified meetings with VCs in New York City for an investment round – all by starting a conversation on LinkedIn. What are your goals for outbound marketing on LinkedIn? If you’re looking for support on meeting them, please reach out!

Plea Bargaining - A Flaw in the Criminal Justice System in the United Essay

Plea Bargaining - A Flaw in the Criminal Justice System in the United States - Essay Example This paper will discuss plea bargaining as a flaw in the criminal justice system. Plea bargaining is defined as a process whereby a defendant in a criminal case and the prosecutor reach a conclusion (which is mutually satisfactory) to end the criminal case at hand, subject to approval by the court. Successful plea bargaining lead to a plea agreement between the defendant and the prosecutor, where the former agrees to be plead guilty to the offence without a trial (Robert and Stuntz 24). In return, the prosecutor consents to make favorable recommendations to the court or dismiss specific charges regarding the case. However, plea bargaining is considered as a flaw in the criminal justice system. Its critics argue that it is a shortcut to justice, and therefore the due process of the law may not be followed fully. Besides, it is considered as a flaw in the criminal justice system because it is deemed to be unfair to criminal defendants. This is because the prosecutors tend to have so mu ch power in deciding the charges that a defendant may face (Hessick and Saujani 197). Also, since the prosecutors are evaluated to a greater extent on their rates of conviction, plea bargaining may force them to try at all costs to win the case. conversely, plea bargaining is a flaw in the criminal justice system because it is likely to soften punishment’s deterrent effect a s the defendant has an opportunity to bargain for lesser punishments (Hessick, Andrew and Saujani 81-82). Origin and Impact of Plea Bargaining Plea bargaining is a critical part of the United States’ criminal justice system; actually, majority of the criminal cases in America are settled using this means instead by jury trial. Plea bargaining traces its origin to the case of Brady v. United States in 1970 when the defendant (Robert Brady) tried to alter his plea after he had agreed to plead guilty to kidnapping for a lesser sentence (Fisher 44). Brady’s move was motivated by the desire to av oid death penalty. However, upon hearing the case, the Supreme Court ruled that his plea was legitimate because had an option of refusing the offer by the prosecutor. Subsequent case also showed that the Supreme Court approved the legality of plea bargaining. In the case of Santobello v New York in 1971, the legality of plea bargaining was challenged when the prosecutor was accused by the defendant of breaching their plea agreement by recommending a punishment that was harsher than the one they had agreed upon. The Supreme Court ruled in favor of the defendant; it argued that legal validity of plea bargaining to be achieved, the defendant and the prosecutor should adhere to the plea agreement’s terms. This case set a precedent that each plea bargaining must be approved by the court for it to be legally valid. Since then it has been entrenched in America’s criminal justice system (Bibas 2471). However, several studies have shown that it affects criminal justice system b y giving the prosecutor more discretion that may lead to unfairness on the part of the defendant and by granting the defendant lesser punishment. The following cases bring the flaw mentioned above: Bordenkircher v. Hayes where the court approved unfair handling of the case by the prosecutor; and in Marshall v. Barlow’s Inc where the defendant was granted lesser punishment despite the gravity

Factor V Leiden and Prothrombin Mutations Essay Example | Topics and Well Written Essays - 500 words

Factor V Leiden and Prothrombin Mutations - Essay Example Mutations are determined in a consecutive series of 100 controls. It argues that fifteen of 80 current miscarriage patients and four out of 100 carry V Leiden Mutation Factor. Its results suggest that the presence of prothrombin and factor V leiden is the cause of recurrent miscarriages. Additionally, it suggests that the presence of both factors of mutations is major in second trimester, fetal loss and dependent of any additional pathology (Foka et.al, 1999). The readability of the journal is on point because the authors did not mix up the information. They have introduced the topic properly, explained everything a reader would want to know, and summed up the whole information. It is credible in the sense that information is well researched and documented. The authors demonstrate well researched and investigated article. This is because they have used analysis methods to determine the above explained topic as well as analyze it, giving a reader a well understanding of the topic. It expounds on Factor V Leiden and Prothrombin Mutations, causes and consequences which gives a reader a good understanding of both mutations ( Foka et al., 1999). Recurrent miscarriages is a health problem affecting, approximately 5% of women in today’s world. Although there is no specific investigation of this situation, researchers argue that factor V Leiden and Prothrombin Mutations are the cause of recurrent miscarriages. Prothrombin Mutations is acquired and inherited by defect. Recently, it was discovered that the most commonly inherited defect is Factor V Leiden which is resistant to activated protein. It is also responsible for all cases of isolated thrombophilia and thrombotic conditions. However, there are still uncertainties on the accurate role of factor V Leiden in terms of miscarriages which has resulted to bias selection of women regarding their fetal losses. This is in terms of the number of miscarriages type,

Some Aspects of Submarine Design Essay Example for Free

Some Aspects of Submarine Design Essay The history of submarines shows there were two significant advances in the performance of submarines, which occurred after full scientific studies were undertaken. The first was by the Germans at the end of World War II when they produced the Type 21, which could have upset the balance in the U-Boat campaign if it had arrived earlier. The second was by the US Navy with Albacore which had a submerged speed of over 30 knots. To neglect full scientific studies would be a serious mistake in the design of any future replacement submarine. Design is shown to be like a jigsaw puzzle where altering one piece requires alterations in all surrounding features to make a workable complete design. The basis of improved hydrodynamic features is discussed. A new nose shape is presented which should improve the performance of the forward passive sonar up to operational speeds. Other major sources of resistance may be improved. It is proposed a first major step should be to establish the detailed performance of Collins using wind tunnels and computational fluid dynamics which will serve as the comparative foundation for any new design.

Hydrodynamics Executive Summary The history of submarines subsequent to the first truly operational vessel, Holland, launched in 1899, showed two significant advances as opposed to steady incremental developments. These resulted from full scientific studies of all the problems. The first of these advances was made by the Germans at the end of World War II, when they produced the Type 21 which had major improvements in range and battery time while their underwater speed increased to 18 knots compared to 5 knots on previous vessels. Design diving depth was increased dramatically. They could operate below the Allies submarine defence weapon systems. The second advance was made by US designers who produced Albacore in 1953 with a shape suited to full underwater operation. Its length-tobeam ratio was only 7. 7 and top underwater speed was 33 knots. The drag coefficient was only 0. 1 compared to 0. 35 on previous submersible designs. It is clear that scientific studies should be a starting point for any future submarine design. A review of the literature covers priorities in design and shows how enhancement of one feature interacts with other features and may even result in an overall loss of performance despite the perceived advantage of the enhanced feature. Hydrodynamic aspects are then discussed starting with the shape and reasons why a length-to-beam ratio of about 7. 5 gives the minimum resistance. All features affecting the resistance are discussed including the boundary layer, laminar flow, transition, turbulence and separation and how the flow over the principle passive sonar should be as quiet and smooth as possible. Added resistance from sails, masts, snorkels and appendages need careful streamlining and attention in design. A proposed profile of a new submarine is presented which has the passive sonar far forward in the streamlined nose with the torpedo tubes positioned further aft. It should be a quieter vessel with more effective sonars. The profile requires shortening to reduce the displacement and then the internals need rearranging. The design process then begins, which is iterative. In order to proceed with such concepts it is vital to have a database. Our current submarine, the Collins class, should be the base from which all changes and proposals are measured. It is suggested detailed wind tunnel studies should be undertaken concurrently with computational fluid dynamic (CFD) evaluations. The results should then be compared with full scale trials to establish propeller efficiencies and roughness factors as well as the contributions for each feature, hull, sail, control fins, masts and snorkels, flood openings and others. This database will allow more precise comparisons for any improvements which may be considered in a future design. Author Prof. Peter Joubert (OAM) Contractor Maritime Platforms Division P. N Joubert, a World War II fighter pilot, after demobilisation from the RAAF, studied aeronautical engineering at Sydney University. He then joined CSIRO, where he designed a radio controlled meteorological glider. Subsequently he was appointed as a lecturer in mechanical engineering at Melbourne University specialising in fluid mechanics. In 1954 he attended the MIT where he built and tested high-speed catamarans in the towing tank. At Melbourne University he built a new wind tunnel and much research was initiated and conducted there. He has authored over 120 scientific papers, most of them in fluid mechanics, boundary layers, roughness, and vortices and recently with a PhD student, the flow about a submarine body in a turn. Over the years he has received many research grants including one from the US Navy. His work with his students and colleagues is recognised internationally such as by the General Motors Research Laboratories and other international ship research bodies. He has been studying flow patterns on submersibles since 1998 and has helped with certain modifications to Collins. In 1972 he was granted a personal chair and since retirement has been invited to continue as a Professorial Fellow. He was awarded a medal in the Order of Australia in 1996 for contributions to road and yacht safety. He was awarded the AGM Michell medal in 2001 by the College of Mechanical Engineers and is a Fellow of the Australian Academy of Technological Science and Engineering. As a yacht designer he has had over 100 yachts built to his designs, including a high-speed catamaran for the world sailing speed record and ocean racing yachts. Some of these have won against world-class competition – the Sydney-to-Hobart race in 1983 and second places in 1968, 2002 and 2003. As a sailor he has raced his own designs in 27 Sydney-toHobart races and survived the storm of 1998. In 1993 he was awarded the Commodore’s medal of the Cruising Yacht Club of Australia for outstanding seamanship after his crew had rescued eight survivors from a sunken yacht at night in a strong gale.
