Freedom Of Religion, Speech, And Press - 885 Words
I think that the constitution was a triumph in republican government for many reasons. The constitution guaranteed basic rights for people, guarded against tyranny and established a new type of government. The basic rights for people included all the amendments. They guarded against tyranny in several ways such as separation of powers and checks and balances and lastly it created a new government by making the power of national and state governments equal. Although the constitutions main goal was to establish a strong government after the failed Articles of Confederation, there are still five parts that take part in protecting individual rights of the people. The Bill of Rights, which is the first 10 amendments. Amendment 1: Freedom of religion, speech, and press. Amendment 2: Right to keep or bear arms. Amendment 3: Protection from quartering soldiers. Amendment 4: Protection from unreasonable search or seizure. Amendment 5: Right to due process of law. Amendment 6: Right to trial by jury, speedy trial, public trial, counsel. Amendment 7: Right to civil by trial by jury. Amendment 8: Prohibition of excessive bail and cruel and unusual punishment. Amendment 9: Protection of rights not enumerated in the Constitution. Amendment 10: Protection of the powers of the states and the people. Amendments 14, 15, 19, and 26 are also other amendments/parts that are for the rights of people.

Spleen In North India Health And Social Care Essay Free Essays
Spleen is a reticulo-endothelial and lymphoid organ and sometimes works as hematopoietic organ. Otherwise this organ is cemetery of RBCs. Spleen is enlarged in assorted clinical upsets e. We will write a custom essay sample on Spleen In North India Health And Social Care Essay or any similar topic only for you Order Now g. infection, metamorphosis or storage upset and haematological abnormalities1,2. Spleen is neââ¬â¢er tangible boulder clay it is enlarged two-three times of its ain size3. There are many manners of probe to place the hypertrophied spleen e.g.-plane radiogram, echography, computed imaging, MRI and radionuclide scan. Out of these modes echography and computed imaging are most dependable for intra-abdominal organs4. Assorted surveies were done by echography to analyze the additive dimension of spleen-length, breadth, and thickness. But CT-based additive dimension are still unavailable. Unfortunately, dimensions determined by 2-D USG are limited preponderantly by the variable, irragular contour of lien but besides by the trouble in wholly scanning the full organ or visualising complete contours as a consequence of the presence of overlying constructions such as bone, intestine gas or kidney5. CT imagination is more accurate than echography because this drawback doesnot occur with com puted tomography6, 7, 8. CT scans of 126 patients ( 72 male and 54 female ) were used to mensurate the volume of lien. The age of patients ranged from 20 to 70 years ( 50.33à ±18.9yrs ) ( Table-I ) . The information was collected from December 2006 to April 2007 with permission of Department of Radio-diagnosis, KGMU Lucknow and informed consent taken from each patient. CT scans were obtained for assorted clinical indicants and followup of abdominal injury, abdominal hurting and to except an abdominal mass or adenopathy. The patient ââ¬Ës organic structure weight and tallness at or near the clip of the CT scrutiny were recorded. Spleen axial and transverse sectional image were obtained a CT Helical instrument. The proficient parametric quantities were 120 kv potency, 120 ma current, 10mm piece breadth with indistinguishable Reconstruction index and a rotary motion clip of 1.5 secs. The medical records of all patients were reviewed. Patients whose liens appeared unnatural on CT scans were excluded. Additio nally, any patients who had clinical, biochemical or imaging grounds of conditions that could impact the size of the lien, haematological upsets, abdominal malignances, infection and portal high blood pressure, splenetic injury, cyst, and auto-immune diseases were excluded from the survey. CT-scan dicom images of each patient were opened in Able-3D-doctor package. Spleen is identified in each cross subdivision and longitudinal subdivision of CT-scan images. The length of lien recorded in longitudinal subdivision along 10th rib in cephalo-caudal way ( figure-1 ) . Width of lien besides recorded in longitudinal way ( figure-2 ) but thickness measured in cross-section image ( figure 3 ) . All dimensions were recorded maximal appreciated in subdivisions for better truth. All statistics were generated by SPSS version 10.The pupil T-test was used for comparing of agencies. P A ; lt ; 0.05 was considered important for comparing of agencies and for arrested development analysis. Association between splenetic dimensions and physical criterions of patients was assessed with the Pearson correlativity coefficient ; to place the exact form of relationship, non-linear arrested development every bit good as additive arrested development was applied. Multiple arrested development analysis was applied in backward stepwise manner to prove the independent consequence of all physical criterions on splenetic parametric quantities. Frank et Al used conventional echography to measure 793 healthy patients ( 17-82yrs. ) and found that 95 % of patients had splenetic length A ; lt ; 11cm, breadth A ; lt ; 7cm and thickness A ; lt ; 5cm9. Niederau et al studied 915 healthy topics utilizing echography and found that average longitudinal and cross diameter of lien to be 5.8à ±1.8 centimeter and 5.5à ±1.4 centimeter severally. These dimensions were much smaller than other surveies because writer did non mensurate maximal dimension10. Picardi et Al. found average longitudinal dimension of spleen ranged from 8 to 11 centimeter ( average: 9.5 centimeter ) 11. Mittal et Al. performed pilot survey of normal measuring of spleen by echography on Rajasthani population and found mean length of spleen 9.40à ±0.91 centimeter in males and 9.34à ±0.95 centimeter in females12. In older topics they found average length of spleen 9.64à ±0.64 centimeter. Spielmann et Al, mean length of lien was found to be 11.4à ±1.7 centimeter in males and 10.3à ±1.3 centimeter in females13. Konus et Al. found average longitudinal dimension: 10.1à ±1.03 cm13. In our survey intend splenetic length in North Indian population was 10.67à ±1.62 centimeter ( female: 10.34à ±1.58 and male 10.91à ±1.67 centimeter, P A ; gt ; 0.05 ) 14. Mittal et Al. measured mean breadth of lien in male every bit good as female 3.45à ±0.59 centimeter and 3.59à ±0.55 centimeter. Average breadth of lien measured by Spielmann was 5.0à ±0.8 in males and 4.2à ±0.7 centimeter in females. In our survey average breadth of spleen 8.61à ±1.58 centimeter ( male: 9.74à ±1.62 centimeter and female 9.26à ±1.66 centimeter, P A ; gt ; 0.05 ) and average thickness of spleen 4.86à ±1.22cm ( female: 4.70à ±1.19 centimeter and male: 4.97à ±1.29 centimeter, P A ; gt ; 0.05 ) .These all dimension of spleen best correlated with tallness of the patients ( scatter plot-1.1, 1.2, 1.3 ) .

Laser Alignment Theory free essay sample
Modern optical metrology uses precise lines and planes in space from which measurements are made. Because this method creates these features using light it has become known as optical tooling. The 35 year old historical development and current technology of laser instrumentation as used in optical tooling is discussed in detail. This includes the how the measurements are made, applications, and the technology of alignment lasers and position sensing targets developed for sensing position within a laser beam or plane.The various geometries used to make alignment measurements are discussed in detail. Applications are discussed and the challenges each poses are discussed. The challenge of long range alignment and the effect of the turbulent atmosphere on the measurement process is discussed along with methods of handling the associated errors them. WHAT IS OPTICAL TOOLING? Optical tooling is a means establishing and utilizing a line of sight (LOS) to obtain precise reference lines and reference planes from which accurate measurements are made with position sensitive targets. 1] Formerly the measurements were done by a person interpreting a scale or optical micrometer by looking through an alignment telescope; today the lines and planes are created by a laser; the measurements are digital and require no interpretation. Optical tooling uses the principle that light travels in straight lines to produce precise measurements that cannot be reached by manual or mechanical methods. Level lines can be established over great distances so accurately that every point is exactly perpendicular to the force of gravity.Plumb lines can be set to a given level. Right angles can be produced quickly and precisely with auxiliary components. In the assembly, maintenance and calibration of industrial equipment or in the alignment of precision systems, one or as many as four basic questions always must be answered: is it straight, is it flat, is it plumb or is it square? A number of techniques have been developed to make these measurements; however, many of them result in inaccuracies so great that proper operation of the equipment involved will be compromised or seriously endangered.The science of optical metrology and alignment makes it possible to achieve the highest degree of accuracy in answering these four import ant questions. It is no longer necessary to interpret readings or to make constant adjustments and calculations. In laser alignment applications, direct, precision measurements are made rapidly and consistently. Straightness In aligning several points, a tight wire is often used as a reference line. This technique has numerous drawbacks and introduces inaccuracy. First of all, wire has weight, which causes it to sag; over long distances this sag can become considerable.In addition, wire vibrates, can bend or kink, and when stretched in the area to be measured, equipment cannot be moved around for fear of disturbing the wire reference line. Even a gentle breeze can cause the wire to move sideways a considerable amount; the aerodynamic drag on a thin wire is huge. In laser alignment, the LOS of is established by a laser beam instead of a tight wire. The invisible LOS reference has no weight, cannot sag, kink, or be disturbed, nor is it a safety hazard. It constitutes a precise, unvarying reference, determining straightness to within thousandths of an inch.Flatness In order to determine flatness a shop level and a straightedge was employed in the past. However, over large horizontal areas, the shop level must be moved from part to part. Consequently, one can only tell the degree of flatness of each individual surface upon which the level is place. Whether all objects in a large area are flat is still in doubt. Flatness over a considerable area must be assured in the erection of large machinery, surface tables and large machine tools. Conventional bubble levels simply do not offer the degree of precision required. Laser levels, a termed that has fallen into generic use, offer a way to produce a level datum over a wide area. Laser technology has overcome the many disadvantages of bubble levels and assures levelness to within a few thousandths of an inch over hundreds of feet. This high degree of levelness is accomplished by horizontally sweeping the laser beam manually or via a motor driven rotary stage. This revolving line of laser light becomes a horizontal plane of sight, giving a precise horizontal reference datum, sometimes called a waterline. SquarenessPerfect squareness implies that one plane forms a 90Ã ° angle with another intersecting plane. When a steel square is used to test for this condition, the results can be very misleading. Such measurements rely upon the trueness of the steel square, which can vary from square to square with time. In addition, steel squares have a definite limit in their physical dimensions and consequently the testing of very large surface becomes inaccurate, slow and cumbersome. Laser alignment overcomes all these disadvantages and offers a quick and precise method for determining squareness.One method is to use a transparent penta prism in conjunction with a simple alignment laser. This optical element will split the beam from the laser into two parts; one beam passes through the prism undeviated, the other beam is reflected at a perfect 90 degree angle. This will be described in more detail later. Other systems use three independently mounted lasers that are orthogonal to each other. Plumb Classically, a plumb bob is used to establish a single vertical reference line. Of course, as vertical distances increase, the plumb bob becomes cumbersome and inaccurate. It takes a long time for the plumb bob to settle.Also, it can easily be swayed by vibration, air currents, and other disturbances which are bound to be encountered. In the laser alignment method there are several ways to produce a plumb reference; it can be a plane or a line. To form a plumb line, an alignment laser with autocollimating capability is used with a pool of almost any liquid. Autocollimation senses the angle of an external mirror by reflecting its beam back into the laser head. A position sensor, beamsplitter and lens measure the angle of the reflected beam. When the laser is adjusted such that the internal sensor reads 0 in both axes, then the laser is producing a plumb line.For example, if a heavy machine tool is being surveyed, the two reference points which determine the LOS should be located off of the machine. If for any reason the machine were to move or deflect all measurements would be in error. The two reference points should be located close enough to be convenient to use and/or out of the way of other people working in the area. Transits and alignment telescopes first made these types of measurements. But the problem with transits and telescopes is that they require a person to interpret a scale placed on the object of interest; and usually a second person is holding the scale against the object. It is a two person job that takes time and much training to accomplish successfully. It is also subject to errors. This type of alignment measurement, commonly called straightness, is the most basic of all alignment applications. The figure below shows an alignment laser source on the left whose collimated beam is striking a position sensor target on the right. The target can freely slide and make measurements of straightness of the structure to which it is attached. [pic] Another common requirement is to establish another LOS perpendicular or parallel to the original LOS.To establish a perpendicular a special prism is used: a penta prism. A penta prism has the property that rotation around its axis does not deviate the reflected beam at all; it does not have to be critically mounted. Penta prisms are often called optical squares, an appropriate term. To establish a parallel LOS to an existing LOS typically involves tooling bars if the distance is relatively short, say a meter or less. These bars are made of steel and hold electronic targets at a precise distance from a center. Using two of them with the original LOS establishes a parallel LOS.If the distance between the two LOS is large, then it can be done using the penta prism twice; the first time to turn the beam 90 degrees, followed by a certain distance, and concluded by turning the beam back 90 degrees. Care must be taken that two LOS are truly parallel; usually using a level reference datum makes the task much easier. The next alignment application involves measuring the alignment error between two different LOS datums; the typical application is to determine the lateral offset and angular error between two shafts.The shafts essentially define the two LOSs. The measurement consists of setting up the source on one shaft and parallel to it. The targets are placed on the second shaft and surveyed. Then the shafts are rotated 180 degrees and surveyed again; the difference is twice the shaft offset. If the target is placed at two axial locations and measured for offset, the difference in the offsets divided by twice the axial separation is the angular error in radians. The figure below shows a typical method to measure shaft alignment errors using a laser and target. [pic]A more sophisticated alignment application is to sweep a laser beam quickly to generate a plane of light. The advantage of this is that many targets can be aligned using one laser source. In simple straightness applications the target location is restricted to the active area of the position sensor. In swept plane alignment, the targets are using sensitive in only one dimension. A typical application to establish a level plane is to put three or more targets at the same (desired) waterline location and adjust the structure the targets are on until all targets read the same.The targets for swept plane alignment can be static, meaning they require the laser beam to be directed in to them constantly. Usually the laser beam is swept by hand by rotating a knob on the laser source. If the laser plane is moving at high speed, say once a second or faster, then the targets must capture and hold the position of the laser beam as the beam sweeps by. The problem becomes harder to accomplish at longer distance because the beam is on the detector for such a short periods of time. The figure below shows a horizontally swept level laser beam scanning by several targets placed on a machine bed.
