How to Pronounce the Spanish RR

How to Pronounce the Spanish RR Pronouncing the RR sound in Spanish can be difficult for some, but its possible to learn! 10 Steps to Master the Spanish RR Sound Keep in mind that there are two R sounds in Spanish: the single R sound and the double R (or RR) sound.Keep in mind that the single R sound is used whenever the single R appears in a word, except when its at the beginning of a word or after an L, N or S, when the RR sound is used.The RR sound is also used to sound the letter combination of rr, which used to be considered a separate letter of the Spanish alphabet.Keep in mind that the Spanish R and RR dont share the distinctive R sound of English. Think of them as separate letters entirely.Remember that the RR is a trilled sound formed by a flapping of the tongue against the front roof of the mouth.Visualize the front of your tongue as a flag flapping in a vigorous breeze.Now try purring like a cat. If youve succeeded, you are approximating the RR sound.Alternatively, relax and pretend youre a child making the sound of a revving-up motor.Another way is to pretend it is extremely cold. Now make the sound of exhaling with your lips flap ping together. Now do the same thing with your tongue against the roof of your mouth. Alternatively, loosely hold the tip of your tongue at the front roof of your mouth. Now try blowing air between the tip of the tongue and roof of your mouth while you partly relax the tongue. Try an Audio Lesson To hear the rr sound in words as spoken by native speakers, listen to an audio lesson on rr. Sample words in this lesson are perro (dog), carro (car), barra (bar, such as one made of metal) and hierro (iron, the metal).

Court case convictions because of fingerprints Essay

Court case convictions because of fingerprints - Essay Example Fingerprinting has been proved to be immensely beneficial to investigators all over the world to nail murders, thieves and law abusers based on latent fingerprints unknowingly left by the perpetrators or criminals. DNA fingerprinting is proved to be the best flawless identification system and as such it has played a pivotal role in solving many controversial court cases such as the Farrow case, Thomas Jennings case, The Mona Lisa case, and the Brandon Mayfield case. There have also been instances in history where DNA fingerprinting error has caused innocent persons to be treated as culprits as in the case of Brandon Mayfield. This paper analyses these four cases in detail to see why DNA fingerprinting was so important in these cases and in doing so the paper also seeks to explore the various advantages of DNA fingerprinting. The Farrow case involving the Stratton Brothers was the first case determined by DNA fingerprinting in London. On March 27, 1905 Thomas Farrow was found dead in his paint shop and a few days later his wife, Ann also died. Even though robbery was identified as the motive for the crime it was very difficult for the Scotland Yard men to make any quick progresses in the case. Two masks were discovered from the spot and the Scotland Yard after their preliminary investigation identified the murderers as the Stratton brothers- Albert and Alfred Stratton. However, there were no solid evidence against the brothers rather than circumstantial evidences and the description given by milkman Henry Jennings. It is at this juncture that a clear fingerprint on Farrow's cash box found in the shop became crucial. The fingerprint was thoroughly examined by detective inspector Charles Collins, one of the founding members of the Scotland Yard's Fingerprint Branch in 1901. He ‘rolled their fingers on the inkpad’ and â€Å"the fingerprint on the tray matched Albert's right thumb to perfection† (Gurdoglanyan, 2011). Collins played a crucial role in convincing the jury of the points of similarities among the fingerprints. The trial history of the case makes it clear that the brothers could have escaped capital punishment if the fingerprint evidence could not be proven. During the trial, the milkman could not identify the Stratton brothers and the fingerprint evidence was ‘the prosecution's only solid evidence’ in the case (Fingerprint evidence is used to solve a British murder case, 2012). Thus, this DNA fingerprinting proved to be crucial in the case and both the brothers were convicted as murderers. The Thomas Jennings case was the first case to be determined based on fingerprint evidence in the United States. The case of Thomas Jennings took place in 1910 and the fingerprint testimony played a crucial role in the final verdict of the murder case. Mr. Hiller was shot dead during his combat with the murderer, Thomas Jennings in 1910. The fact that Jennings had left four fingerprints of his left hand on the rai lings at the rear kitchen window through which he entered the home of the Hillers became a solid evidence and turning point in the case. During the trial, fingerprint expert William M. Evans of the PDBI could prove beyond doubt that the fingerprints on the railings belonged to Jennings alone and this prompted the appeal court to affirm the verdict of the jury to offer him capital punishment

International business Essay Example | Topics and Well Written Essays - 2500 words - 13

International business - Essay Example nce, it is an effort to integrate or transverse some of national boundaries that reduce the national barriers and the businesses can compete for productive inputs and customers across the globe. In other words, it can be explained as an effort to reduce national barriers and establish broader market that permits all buyers and sellers to persuade business activities at a global level. The process of globalization can not only be identified as a buzz word but it will provide opportunities to accelerate pace of major business. Despite the fact, globalization will provide greater opportunities for the business to expand its markets, improve the pace of its performance and productivity. Globalization still remains to be one of the debatable and controversial issues in contemporary times. Researchers claim that the globalization is an excellent concept to boost up economic prosperity but elimination of national barriers cannot be attained. It has created a confusion and paradox situation for the business entities to integrate its operations at a global platform. The statement ‘The problem with the globalization is that there is not enough of it’ indicates that the concept of globalization is not absolutely attainable that has created problem itself. Therefore, the present essay paper will critically analyze advantages and disadvantages of Globalization to interpret the statement. Werhane (2012) explains globalization as an integration process of national economies within the international economy, through trade flows, foreign direct investments, short capital flows, technologies flow and labor forces (Werhane, 2012). The integration of the economies has increased diversity, complications, and controversies because of its multi dimensional nature. Sebastian and Elisabeta (2014) Claim that with the passage of time globalization stresses on the increasing process of integrations among countries within regional economies and political structures, with respect to

Philadelphia Healthcare System Assignment Example | Topics and Well Written Essays - 750 words

Philadelphia Healthcare System - Assignment Example The Philadelphia healthcare system can be termed as one the most developed health care system. The hospitals in this area are equipped with more than 300 beds which gives them a capacity of over 300 inpatients. A large number of beds in hospitals indicates that the hospitals in these regions are well equipped with facilities to take good care of inpatients. The capacity of a health care system is a critical factor in any region in a country. A large capacity allows the hospitals to respond to emergency matters and guarantee the patients of quality health in a time of need. The availability of these facilities ensures better health care, lower mortality rate and a healthier public in the country. The high capacity of the medical hospitals in Philadelphia indicates that the hospital has the capacity to take care of the health needs of the society. Also, the availability of this capacity indicates that the health system has enough medical personnel to take care of the health needs of th e society. Judging from this capacity, it is possible to regard Philadelphia as one of the best medical health systems in the United States. The hospital care intensity index is one the ratios that are used to measure the quality of healthcare within a health system. This figure provides the ratio between the number of days that a patient stayed in hospital and the number of times that they received attention from the medical staff within the hospital. In essence, this ratio is a representation of the availability of medical staff which in turn indicates the degree to which a healthcare system is equipped with medical personnel.

The Electromagnetic Testing: The Eddy Current Testing

The Electromagnetic Testing: The Eddy Current Testing In modern NDT methods electromagnetic testing plays an important role. Electromagnetism is a part of ndt process. It is a process based on inducing magnetic field. The process of inducing an electric current and magnetic field or both inside a test material. Then observe the magnetic flux induced in the material. This method is based on the electromagnetism. Electromagnetism is the property of a material to get magnetic effect while an electric field applied. The main factor of this test is that the material should be a conductor. These methods give more benefits and advantages than other tests. The major tests coming under the electromagnetic testing are, Eddy current testing Flux leakage testing Alternating current field testing Remote field testing Among these techniques my topics are Eddy current testing Flux leakage testing EDDY CURRENT TESTING Eddy current testing is relatively applicable in small materials. It gives good measurements on ferromagnetic materials. The basic principles of eddy current testing are electromagnetism and permeability. More details about eddy current testing is shown in the coming pages. FLUX LEAKAGE TESTING Flux leakage is another electromagnetic tesing.It is widely used. Electromagnetism is the basic principle of flux leakage testing. This method is most commonly used in pipe lines and storage tanks. After inducing magnetic field we are able to analyzing the defects through instruments. Other electromagnetic techniques are, ALTERNATING CURRENT FIELD MEASUREMENT ACFM methods are used to detect surface breaking cracks. This method can be applied to both magnetic and nonmagnetic materials.ACFM method is based on the electromagnetism and these entirely different from eddy current method.ACFM method gives us more benefit than other methods. It does not need the removal of paintings and coating.ACFM technique is more advanced testing than dye pentrant testing and magnetic particle testing. The main advantages of ACFM tastings are Able to work on coatings No need to cleaning more Does not require equipment shut down High speed inspection REMOTE FIELD SENSING METHOD RFT is the commonly used electromagnetic method in ndt. Remote field testing method also joined with eddy current testing is named as remote field eddy current testing. But in practically there are many difference shows between eddy current testing and remote field testing.RFT technique is mainly used to find out the thickness of the ferromagnetic material tube walls. Here RFT shows more sensitivity than eddy current testing. The main principle of RFT is the electromagnetism. In RFT, the probe contains transmitter zone and receiver zone. The remote field shows more coupling to the exciter coil and receiver coil. The main advantages of RFT are, High sensitivity Give accurate measurements from sheets and plates. Ability to inform internal defects Detect defects from the ferromagnetic tubes EDDY CURRENT TESTING Eddy current testing is used in a variety of industries to find defects and also measurements. Major use of eddy current testing is for defect detection when the nature of the defect is well understood. Naturally the method is used to test relatively small area and the probe design and test parameters must be established with a good understanding of the flaw that is to be detected. Eddy current testing only used to detect surface and near surface defects. In thin materials such as plates and sheets, eddy currents can be used to measure the thickness of the material. This shows eddy current is useful for detecting corrosion damage and other damage that causes a thinning of the material. The method is used to make corrosion thinning measurements on aircraft skins and in the walls of tubing used in assemblies such as heat exchangers. Eddy current method is also used to find the thickness of paints and other coatings. Eddy currents are varied with respect to the electrical conductivity and magnetic permeability of materials. So eddy current testing can be used to arrange materials and also find which heat treatment applied to the material. It is the main advantage and use of eddy current testing method. In Eddy current testing different probes or transducers are used. Compare to other testing methods eddy current testing shows many advantages and applications. Transducers used in eddy current testing is depend upon the properties and size of the material. PRINCIPLES In eddy current testing the major principles are, Electromagnetism Permeability ELECTROMAGNETISM The main principle of eddy current testing is the à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€¹Ã…“electromagnetismà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢. This states that à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€¹Ã…“when an electron is passing through a conductor, a magnetic field induced on the conductor perpendicular to the axis. The same effect happens in a copper wire while alternating current passing through it. When the alternating current expands then the magnetic field also expands. The magnetic field obtained through electro magnetism is similar to the bar magnet. PERMEABILITY Permeability is also relating to the electromagnetism. It is also called as magnetic permeability. Permeability is ability to permeable. It is a constant of proportionality exists magnetic induction and magnetic field intensity. Permeability of some materials has been change according to the temperature changes and magnetic induction. PRINCIPLE OF EDDY CURRENT TESTING IMAGE-1 NB: COURTESY TO MARKTEC FROM MARKTCC.CO PRACTICAL METHOD Eddy current testing is used in different sectors for fin out the thickness and used to check the material losses in different materials. The cause of material loss is corrosion. It mainly used in thin sheets, plates and also in aircraft components. On the impedance plane, thickness variations exhibit on the eddy current signal response as a subsurface defect. Except that the signal represents a void of different size and depth. Due to this the phase rotation should be same and the amplitude should be greater. In the device the lift-off curves for different areas of taper wedge can be produced by nulling the probe in the air and touching it to the various surfaces at various locations of thee tapered wedge. A comma shaped curve is formed while a line is drawn between the end points of the lift-off curves. In the second stage the comma shaped curve path is traced on the screen when the probe is scanned down the length of the tapered wedge. So that the entire range of thickness values are measured. The important thing is that the depth of penetration of the eddy currents must cover the range of thickness being measured. Then a frequency is selected that produces standard depth of penetration at maximum thickness. Lower frequency is needed for getting high penetration. Due to the probe impedance is more sensitive to changes in electrical conductivity. So electrical conductivity cannot be phased out and is important to verify the conductivity of below the region of low level. If testing need more penetration single coil probe, reflection type probe and transformer probes are used based on configuration. Small diameter probe coils has the efficiencies to give very high sensitivity. EDDY CURRENT TESTING ON A BORE IMAGE-2 NB: COURTESY TO: BAM.DE TFROM BAM.DE EDDY CURRENT INSTRUMENTS In industries various eddy current instruments are used. Analog and digital display instruments are mainly used. Classification of eddy current instruments is based on the display used for presenting the data.

The main applications are, Crack detection Material thickness measurement Coating thickness measurement Conductivity measurement Material identification Hest damage detection 2. ELECTROMAGNETIC FLUX LEAKAGE TESTING Magnetic flux leakage is an important method in NDT process. Magnetic flux leakage method can be used to detect the circumferential cracks on the stainless steel and metal losses in ferromagnetic materials. It is widely used in tubes and heat exchangers for find out the discontinuities. The major principle of magnetic flux leakage testing is the electromagnetism. During MFL inspection a magnetic field induced on the material. This property of material is termed as electromagnetism. MFL tools consist of two or more bodies while inspecting tubes and complicated material models. The main body is named as magnetizer with magnets and others are batteries and electronics.MFL tool is able to find sensor readings based on either the distance of tool travelled or on increment time. In flux leakage examination of tubular parts three types of defects can be detected. They are longitudinally oriented, transversely oriented, silvers. Magnetic flux leakage testing has some limitations in sizing the capacity of defects. In compare with eddy current testing magnetic flux leakage testing shows more sensitivity and advantages. In magnetic flux leakage testing method of tubular products both outside and inside diameter defects can be detected but generally they cannot be distinguished. WORKING PRINCIPLE The main principles of electromagnetic flux leakage are, ELECTROMAGNETISM The main principle of MFL is that electro magnetism. This states that when electron is passing through a material a magnetic flux induced on the conductor. The magnetic field should be perpendicular to the axis. An electromagnet is an object, which acts like a magnet and its magnetic effect created and controlled by electricity. HALL EFFECT Some Hall Effect sensors are used in electromagnetic flux leakage testing. Hall Effect is the production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. PERMEABILITY Permeability is also related to the electromagnetic field. It is the ability to become permeable. Permeability changes occur in some material with temperature changes and magnetic induction. PRACTICAL METHOD Magnetic flux leakage testing was used earlier because eddy current cannot detect subsurface defects in ferromagnetic test material. In such a situation a common technique using encircling coils but them sometimes inconvenient while using in internal coils. Flux leakage testing is used at steel mills and fuel mills for getting correct measurements without errors. When ferromagnetic material that is free from defects is magnetized, then an unbroken flux field flows through the object material. The magnetic flux flows through between its poles. Next the flux density decreases towards the outer material surfaces and a detector of flux leakage testing would pick up a very weak signal from the surfaces. However, if the surface is interrupted by a discontinuity, poles are formed at opposite sides of the resulting gap. Then the flux lines flow externally from the north to South Pole. The flux leakage lines are detected by a transducer or probe passing over the discontinuity and signal is displayed. Disturbance of the materials original flux lines also extends under the discontinuity and if the material wall is thin itself, a discontinuity on wall surface may be detected from the opposite wall. After getting the signals from the detector we have to find out the length, thickness and measurement about the defect through monitoring.MFL gives us to the ability to detect the surface and subsurface defects.

Implications of Omnipotence :: essays research papers

Implications of Omnipotence The concept of omnipotence seems to reign prominent among most religions, specifically among their myths articulating the origin and the inevitable destruction of our universe. Omnipotence, meaning all-powerful/perfect and predictably all good, produces many contradictions and questions merely by definition. The prospect of a life form being omnipotent is impossible. For the omnipotent being would inexorably be the creator and destroyer of all things; however, a perfect (omnipotent) being needs not to create anything else, for it is perfectly harmonious in its state, let alone creating an imperfect universe necessary for destruction. Every race, culture, and individual for the most part seem to have some grasp on a deity or deities that omnipotently created everything and all-lovingly watches over all. Some people will declare these beings’ omnipotence as fact and infallible, but with no deliberation of the entire scheme of things. Most believers, with some exceptions, say that one must have faith, and irrelevantly tack-on, â€Å"Our god(s) is all-powerful, and loves all his/their children however imperfect they may be.† If something is perfect and all- powerful then nothing imperfect can come from it. This also proves that the concept of opposition would not exist; everything would perpetuate in perfect harmony. Most monotheistic religions such as Christianity, Islam, Judaism, etc. believe in a single omnipotent god that loves man above all as sons and daughters. If such a being exists and is truly omnipotent, why is there so much pain? Man suffers from plague, war, and natural disaster. How does m an’s agony in any way depict an all-knowing and all-loving being? Followers often use the sayings: â€Å"It is his (omnipotent being) will† or â€Å"He (omnipotent being) works in mysterious ways,† in order to justify man’s constant sorrow before this being’s feet. According to the Bhagavad-Gita (Hindu sacred book), when â€Å"all the radiance of a thousand suns were to burst at once into the silent sky, that would be like the coming of the Mighty One. I am become death, the shatterer of worlds.† With the presence of nuclear power, this quote seems somewhat disheartening; nevertheless it reiterates the fact that if there is a force above all, it being omnipotent is unfeasible.
