Oxycodone is a Schedule II controlled drug, meaning that it has a high potential for misuse, with use potentially leading to severe psychological or physical dependence. Additionally, use of the drug carries the risk of drug interactions and overdose. As a result, taking it safely requires knowing how long it stays in your system. Oxycodone is able to be detected in your blood for about a day. The drug can, however, still be detected in certain types of drug screenings for as many as three months after use.  It can be detected by urine, blood, saliva, and hair tests. Oxycodone comes in a variety of forms including a liquid solution, tablet, and capsule. Extended-release versions exist as well. Common brands include Percodan, Percocet, Tylox, OxyContin, Roxicodone, Roxicet, and Endocet. As an illicit street drug, its commonly known as oxies, OC, and hillbilly heroin. How Long Does Oxycodone Stay in Your System? Urine: Up to four daysBlood: Up to 24 hoursSaliva: Up to four daysHair: Up to 90 days How Long Does It Take to Feel Effects? The regular forms of oxycodone are taken every four to six hours while the extended-release forms are taken every 12 hours. The onset of pain relief action occurs 10 to 15 minutes after taking a single oral dose of medication. For most people, peak pain-relieving effects can be felt between 30 and 60 minutes after taking a dose.?? Peak blood levels occur 30 to 60 minutes after ingestion. For extended-release forms, theres a second release in about seven hours. When you first start taking oxycodone, you should reach steady levels of the drug in your bloodstream after 24 to 36 hours. Plasma levels of oxycodone can be higher in women, the elderly, and people with renal or liver impairment.?? Oxycodone works by changing the way your brain and nervous system respond to pain. It also depresses the central nervous system, so your breathing, heart rate, and other essential functions are affected. Oxycodone may also cause some side effects that can include: DrowsinessHeadacheFlushed skinMood changesDry mouthStomach acheConstipation More serious may include changes in heart rate, nausea, vomiting, chest pain, hives, swelling, lightheadedness, and seizures. If you experience any of these symptoms, you should contact your doctor or emergency services immediately.   How Long Does Oxycodone Last? Your body breaks down oxycodone in the liver into noroxycodone, oxymorphone, and noroxymorphone. These are then excreted by the kidneys into the urine. The half-life of oxycodone, which refers to the amount of time it takes half the drug to be effectively eliminated from your body, is about 3.2 hours; the half-life for the time-released version (OxyContin) is about 4.5 hours.??  It takes several half-lives to fully eliminate a drug, and everyone metabolizes medication differently, depending on factors such as age, weight, genetics, and even specific health issues. Over time, you may develop a tolerance to oxycodone, which means that it might not relieve pain as well as it originally did. Talk to your doctor if this happens. Never take more than your prescribed dose of oxycodone. Your doctor may decide to increase your prescribed dose or switch you to a different type of pain reliever. Oxycodones action  is effectively eliminated from the blood in 22.5 hours. For most people, the effects of the drug will be completely worn off after 24 hours. However, the drug remains detectable in the body for much longer, even after its effects have worn off. Oxycodone will be detected by typical employment, medical, and forensic drugs of abuse screening tests. With a home testing kit, someone who has taken oxycodone will start to test positive for the drug within one to three hours, and the result will continue to be positive for one to two days, according to the Food and Drug Administration (FDA).?? The following is an estimated range of times, or detection windows, during which oxycodone can be detected by various testing methods. Urine Oxycodone is detectable in a urine test for three to four days after the last dose. A standard urine drug screen usually does not test for oxycodone, so additional tests must be used to detect the presence of the drug.   Blood In blood tests, the drug is detectable in for up to 24 hours. Saliva Oxycodone can also be detected by a saliva test for one to four days after use. Hair The drug can be detected by a hair follicle test for a much longer period of time than other test typesâ€"up to 90 days. These are only estimated as the metabolism of oxycodone varies. If youre taking oxycodone by prescription, you should disclose this to the laboratory so they can interpret your test results accurately. Factors That Affect Detection Time There are a number of factors that can play a role in how long oxycodone can be detected in your body. Duration of Use Oxycodone can build up in your body, so if you have been taking oxycodone for pain for some time, it will be detectable for a longer period of time after you have taken your last dose. If you are taking a drug test, you should inform the lab even if you have stopped taking the drug. Age Studies have shown that older adults clear the drug from their systems at a slower rate than younger adults. In clinical trials, participants over the age of 65 had blood concentrations of the drug 15% higher than younger adults.?? Sex Research has also found that women have blood plasma concentrations of oxycodone that are 20% higher than men, even after accounting for differences in body mass index (BMI) and body weight.?? Kidney Function People with impaired kidney function clear oxycodone at a slower rate. Research has found that people with kidney problems have blood plasma concentrations of the drug that are 50% higher than those with normal renal function. Liver Impairment People with impaired liver function may also take longer to clear oxycodone from their systems. For this reason, the FDA recommends that those with liver problems should take starting doses that are a third or half of the usual beginning dose. How to Get Oxycodone Out of Your System There are a few things that might help slightly speed up how quickly oxycodone is processed and eliminated from your system.   The first step is to stop taking the drug; however, you should never stop taking your medication without first talking to your doctor. Because oxycodone can lead to physical dependence, you may experience symptoms of opioid withdrawal if you stop taking it suddenly. Once you have safely discontinued use of oxycodone, you can speed up the drugs clearance from your system by staying well-hydrated, getting regular exercise, and eating a healthy diet. Drinking plenty of fluids can help dilute the presence of the drug in urine, while physical activity and nutritious eating might help boost your bodys metabolism of the drug. Symptoms of Overdose Knowing how long oxycodone remains in your system is important because of the threat of overdose and dangerous interactions with alcohol and other medications. If you take more of the drug to relieve pain after the effects of your last dose wear off but before the drug is out of your system, you increase your risk of an overdose. You will also risk an overdose if you crush, cut, or chew an extended-release capsule or tablet before consuming it, as this will release the entire dose immediately rather than allowing for timed delivery. Even when you  take the recommended dose of oxycodone, you may experience side effects such as confusion, drowsiness, constipation, and nausea.?? If you take too much oxycodone, these side effects can become very serious. Here are some possible side effects of an overdose of oxycodone: Pinpoint pupilsConstipationNauseaSpasms of the stomach or intestinal tractVomitingLow blood pressureWeak pulseComaDrowsinessPossible seizuresBreathing issues (breathing may become difficult, slow, or shallow, or may cease)Bluish-colored fingernails and lips If someone overdoses on oxycodone, call 911 or the national toll-free Poison Help hotline (1-800-222-1222). Understanding Opioid Overdoses Getting Help Oxycodone can be habit-forming, so its important that you not take more, take it more often, or take it in a different manner than prescribed by your healthcare provider. You could be especially at risk for becoming dependent on oxycodone if you have family members with alcohol use disorders, even if theyve never used illicit drugs or misused prescription drugs.?? If you have such a family history, you should inform your healthcare provider and make sure you only use oxycodone as directed. Talk to your doctor if you want to reduce or discontinue taking oxycodone. Your doctor can help you safely stop taking the drug without experiencing withdrawal and prescribe other medications that can help manage your pain. Being dependent on the drug is not the same as being addicted. Dependence means that your body is used to the drug, so stopping cold turkey can lead to potentially serious complications that can include insomnia, vomiting, rapid heartbeat, and increased respiration. To avoid this complication, your doctor may opt to gradually decrease your dosage over a period of time, a process known as tapering. If you need help with an oxycodone addition, your doctor can help. There are medications can help with the withdrawal process including methadone and buprenorphine. Your doctor may also recommend other medications to treat withdrawal symptoms such as antihistamines, sleep aids, and over-the-counter pain relievers. Treatment options may include inpatient or outpatient addiction treatment centers. You may work with your primary care physician, but your doctor may also suggest psychotherapy provided by a psychiatrist or other mental health professional. Some psychological treatments for addiction include cognitive-behavioral therapy, motivational interviewing, motivational enhancement therapy, and contingency management. You can also contact the Substance Abuse and Mental Health Services Administration (SAMHSA) at 1-800-662-4357 or use their online tools to find treatment options in your area.

The tutorial gives a brief introduction to the PicoBlaze microcontroller, and then steps through the following: †¢ †¢ †¢ †¢ Writing a small PicoBlaze assembly language (. psm) file, and stepping through the process of assembling the . psm file using KCPSM3. Writing a top level VHDL module to connect the PicoBlaze microcontroller (KCPSM3 component) and the program ROM, and to connect the required input and output ports. Connecting the top level module inputs and outputs to the switches, buttons and LEDs on the Spartan-3E board. Downloading the program to the Spartan-3E board using the Project Navigator software. 1. 1 Design Functionality The code written in this tutorial reads the values of the four switches and the four push buttons, and displays the current values on the eight LEDS. 1. 2 Relevant Documentation Before commencing this tutorial, it would be helpful to download the Spartan-3E FPGA Starter Kit Board User Guide [1], and the PicoBlaze 8-bit Embedded Microcontroller User Guide [2]. 1. Pre-requisite Knowledge Before commencing this tutorial, the user should work through â€Å"The Spartan-3E Tutorial 1: Introduction to FGPA Programming† [3]. 1. 4 Scope This tutorial is designed to help the user who is just starting to â€Å"get into† using the PicoBlaze with the Spartan-3E. It steps through the process of creating a very simple PicoBlaze program, running the assembler, putting the VHDL components together in Project Navigator, and downloading the final program to the board. It is not designed to be a tutorial on VHDL syntax or to provide detailed information on the PicoBlaze. For help with VHDL, the user can consult with a number of textbooks on the subject, such as [4,5], or find help online. The book by Chu [6] is also a useful reference for the Spartan-3 with many useful examples. Reference designs for the Spartan-3E can also be found here [7]. For detailed information about the features and instruction set of the PicoBlaze, the user can consult the documentation in [2,8]. Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 16 Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 17 2. 0 Equipment The following are required to work through this tutorial: †¢ The Xilinx ISE Project Navigator software. Version 14. 3 was used in this tutorial, but older versions of the software can be used. The software can be downloaded with a free WebPack license from the Xilinx website, http://www. xilinx. com/. The user will need to register and log in. The Spartan-3E Starter Kit, including the Spartan-3E development board, power cable and USB cable for PC connection. The Spartan-3E development board is shown in Figure 2. 1. The Picoblaze 8-bit Microcontroller software. The software can be downloaded for free from the Xilinx website, http://www. xilinx. com/. Again the user will need to register and log in. If a 64-bit machine is being used, software which can run 32-bit DOS programs, such as DOSBox, will be needed to run the KCPSM3 executable. DOSBox can be downloaded from http://www. dosbox. com/. †¢ †¢ †¢ Power JTAG ON/OFF Reset Button FPGA USB LCD LEDs Push Buttons Figure 2. 1: Spartan-3E Development Board. SW0-3 Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 18 . 0 Background – The PicoBlaze Micocontroller The PicoBlaze is an 8-bit RISC microcontroller which is specifically designed and optimized for the Spartan-3 family. One of its main advantages is its small size, requiring only 96 FPGA slices. It is provided as a free, source-level VHDL file with royalty-free re-use within Xilinx FPGAs [2]. Figure 3. 1 shows that the PicoBlaze consists of two components. The KCPSM3 component provides the ALU, registers, scratchpad RAM etc. The Block Memory (Program) component stores the instructions to be executed. This typically consists of a Block RAM, of 1024 bytes in size. Figure 3. 1: PicoBlaze components [8]. The basic design process using the PicoBlaze follows the steps below: 1. A PicoBlaze program is written in assembly language. This file is given the extension . psm. 2. The KCPSM3 assembler is run on the . psm file, and a VHDL file (extension . vhd) which embeds the instructions in the Block Memory component, is output. The name of the . vhd file will be derived from the name of the . psm file, i. e. , if the . psm file is myprog. psm, then the . vhd file will be myprog. vhd. 3. The VHDL code for the Block Memory and KCPSM3 modules is loaded into Project Navigator. Further VHDL code will need to be written to connect the two modules and interface to the outside world. 4. The project is compiled using the Project Navigator Software, and ultimately downloaded to the Spartan-3E board (or other target hardware). Figures 3. 2 and 3. 3 show the VHDL component declarations for the KCPSM3 and Block Memory respectively. Note that the name of the Block Memory component is derived from the name of the original . psm file, i. e. , if the . psm file was myprog. psm, the Block Memory component will be called myprog.

In addition, it is possible to download a new program into the Block Memory, using the JTAG port on the Spartan-3E board. This can provide a convenient means to update the program without having to recompile the VHDL code in Project Navigator. This is not covered by this introductory tutorial, and the user can refer to documentation such as [3] for more information. Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 20 4. 0 Procedure Part 1 – PicoBlaze 4. 1 PicoBlaze Download 1. Download the file KCPSM3. zip from http://www. xilinx. com/. The version of the software for the Spartan-3 family should be chosen. 2. Unzip the file. After unzipping, the files should appear as shown in Figure 4. 1. Figure 4. 1: KCPSM3 files after unzipping. The file KCPSM3_Manual. pdf is listed as reference [8] in this tutorial. 4. 2 Copy Files 1. Create a directory called tutorial_2 in an appropriate location. This will be the working directory for the rest of this tutorial. 2. Copy the following files in the Assembler directory into tutorial_2: †¢ †¢ †¢ †¢ KCPSM3.

Open a text editor (for example, Notepad or Wordpad), and enter the text shown in Figure 4. 2. The text consists of a very simple program written in the KCPSM3 assembly language. The program runs in an infinite loop, reading the contents of an input port at address 00h (connected to the switches) into a register, and writing the contents of this register to an output port at address 80h (connected to the LEDs). Characters which appear after a â€Å";† in each line are comments. ; ; ; ; ; Simple loop that puts contents of input register into the output register switches DSIN $00 LEDS DSOUT $80 ; read switches into register s0 ; write contents of s0 to output port 80 – leds. ; loop back to start start: INPUT s0, 00 OUTPUT s0, 80 JUMP start Figure 4. 2: Simple PicoBlaze program. . Save your file to tutorial. psm, in the tutorial_2 directory. If using Notepad, be careful not to save the file as tutorial. psm. txt. The name of the file should be restricted to 8 characters. The tutorial_2 directory should now contain the files shown in Figure 4. 3. Figure 4. 3: Files in the tutorial_2 working directory. Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 22 4. 4 Running the Assembler As shown in Figure 4. 4, the assembler takes the . psm file as input, as well as three Block RAM initialisation templates. Fifteen different output files are produced. In this tutorial, we will be using the . vhd output file. Figure 4. 4: KCPSM3 assembler files [2]. The assembler is a DOS executable file, KCPSM3. exe, which can be run in a DOS Command Prompt window. 4. 4. 1 32-bit Operating Systems 1. Open a DOS Command Prompt window by selecting: StartAll ProgramsAccessoriesCommand Prompt 2. Use the cd command to change into the tutorial_2 working directory, as shown in Figure 4. 5. Figure 4. 5: DOS Command Prompt window, after changing to working directory. Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 23 3. Now type the command KCPSM3 tutorial. psm, as shown in Figure 4. 6. Figure 4. 6: DOS Command Prompt window, with KCPSM3 command typed in. After entering the command KCPSM3 tutorial. psm, numerous messages should fly past on the screen, ending with â€Å"KCPSM3 successful. KCPSM3 complete†, as shown in Figure 4. 7. After the assembler has successfully run, the working directory should contain many more files, as shown in Figure 4. 12. Figure 4. 7: DOS Command Prompt window, after KCPSM3 successfully run. 4. Type exit to close the Command Prompt window. Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 24 4. 4. 2 64-bit Operating Systems The KCPSM3 executable will only work on 32-bit operating systems. If you are using a 64-bit machine and attempt to run KCPMS3 in a DOS Command Prompt window, the error message shown in Figure 4. 8 will appear. Figure 4. 8: Error message which appears if it is attempted to run KCPSM3 on a 64-bit machine. One way to work around this and run KCPSM3 is to use the DOSbox software, which can be downloaded from http://www. dosbox. com/. 1. Download and run DOSBox. 2. Mount the working directory and change into this directory. When DOSbox is started up, a command window which resembles the DOS Command Prompt window appears. However, it is first necessary to mount the working directory to a drive letter before being able to enter this directory and run programs. This is done with the mount command: mount Figure 4. 9 shows the commands entered to mount and change into the working directory. In this case, the working directory is mounted as drive letter c. The command c: is then used to change into this directory. Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 25 Figure 4. 9: DOSBox window, commands entered to mount and change into the working directory. 3.

A look into Scotland, PA and its relationship with Macbeth Essay Example

A look into Scotland, PA and its relationship with Macbeth Essay The play Macbeth is perhaps one of the shortest Shakespearean tragedies that have endured throughout the generations where the performance of the play is staged all across various countries from afar. Centering on the notion that the greed for power has its surmising impacts on friendship as betrayal gets in the way of the person who engages into the dangers posed by such an act, the play has been constantly and popularly adapted and reinterpreted in numerous ways. Billy Morrissette’s movie adaptation of the play Scotland, PA is one of the many attempts of redefining the context of the original Shakespearean tragedy and subtly utilizing the core elements such as the plot of Macbeth in order to bring about a rather unusual interpretation of the tragic text.The result, however, is one that appears to deviate from the general â€Å"feel† of the play as the movie in its entirety is both riddled and littered with comical antics that primarily involve the characters among the sequences of scenes. As Shakespeare’s Macbeth is, strictly speaking, a play that is treated as a tragedy and one that is by itself a tragic story, the movie on the other hand takes the other side even though faint semblances from the original play appear beneath the jovial parts in the movie.Nevertheless, one cannot simply dismiss away the observation that the core assumption behind the movie Scotland, PA is that it seeks to redesign the â€Å"outside† image of the tragic play by utilizing the comical boundary. Even if one can effortlessly make the assertion that the movie differs from the play in the context of the â€Å"feel† of the film such as tragedy and comedy, it remains a fact that the play underlines the main content of the movie and that the movie on the other hand seeks to reestablish the play by adopting the plot of the latter in a comical manner.From the play to the movieIn the play, one can find the portrayal of Duncan, the King of Scotland as an obvious equivalent to that of the movie’s Norm Duncan who stands as the central person in charge of the burger joint. Macbeth, in its general form, entails the story of a subordinate, Macbeth, who thirsts for power and attempts at claiming the position by murdering King Duncan of Scotland. Whereas in the movie, a seeming parallel is easy to spot such as the situation wherein Joe Macbeth murders his boss Norm Duncan in order to finally relieve the latter from his rank and pass-on the title to Joe.The murder scene of the superiors in both the movie and the play appear in a similar fashion, at least in the context of the plot. Although the exact details as to how the murder was plotted and achieved as well as the setting of the scene widely differs in the context of the comic movie and the tragic play, it remains a strong contention that both agree on the same underlying theme: the murder of the superior by the subordinate in order for the subordinate to claim the power and auth ority of the former.In the movie, the scene wherein Norm Duncan is murdered by Joe Mcbeth employs a tactic that would shroud the case with mystery from the watchful eyes of the police authorities through the use of a planned robbery. This is largely contributed to by Pat Macbeth who is Joe â€Å"Mac† Mcbeth’s wife by carefully planning a scheme that will lead Joe and his wife off the police hunt for the killer. However, Lieutenant Ernie McDuff is firmly convinced that there is more to what has been made to be known from the case and is quite suspicious of the actions of Joe Mcbeth, having the unripe notion that perhaps the latter has a great deal to do with the mysterious death of Norm Duncan.In the original text of the play of Shakespeare, Duncan decided to spend the night in the castle after his visit which eventually led Lady Macbeth to hatch a plan to murder the King of Scotland. The primary reason behind this ploy from Lady Macbeth rests on the observation that Ma cbeth has the ambition of usurping the power off the hands of the king which amounts to the most effective way of achieving it—to murder the king and grant Macbeth the seat of the king. Eventually, the progression of the play reveals to us the situation wherein Duncan is murdered by Macbeth after following the scheme plotted by his wife in order to avoid the possibility of arriving at a conflicting situation wherein their guises are revealed to the public and to the authorities. While the case has been shrouded with obscurity, Macduff, however, remains suspicious towards the gestures of both Macbeth and Lady Macbeth yet keeps his suspicion to himself outside the knowledge of the public.These two scenes in the movie and the play respectively share the same light in the sense that both amplify the instance wherein the superior is murdered by the subordinate, aided in no small way by the careful schemes of their wives, in order to seize the position of authority off the hands of their leaders. The murder scene in the movie reflects one of the film’s crucial relationships with the text, such as that the scene interweaves the underlying plot similar to that in the play. Essentially, utmost importance must be given to the play primarily because it serves as the foreground upon which the murder motif in the movie is derived.The inclusion of the murder scene in the play is of utmost significance in order to bring into full observation the consequent similarities between the versions of the story. Without this scene, one can find it hard to lock together the subsequent themes and the interplay of characters with the movie’s progression. The movie itself would have taken another course in establishing the development of the story’s plot and the ensuing roles of the characters granted that the murder scene was excluded. Indeed, had it not been for the inclusion of the scene with regards to the grand scheme of the plot, one can hardly find any distinguishing similarities between Macbeth and Scotland, PA. It leaves little room for comparison, in obtaining the unifying parallels between the two, and in making the claim that the movie is indeed drawn from the main plot of the tragic play.The notable differences between the murder scene from the text and to that of the movie are the details involved in substantiating further the attributes of the characters. In the play, the specific roles of the characters by far stand-out as the most imminent distinguishing mark that sets it apart from its film remake and vice versa. Moreover, not only do these specific roles define the indicators of differences from the two, these roles also define and illustrate the very context of the setting upon which the characters take part. The very term â€Å"king† obviously leads us to a mental picture of a monarchy usually associated with the feudal times or during the years when political authority rests not on presidents or on any other modern forms of government. In the movie, the idea of a â€Å"king† is not explicitly portrayed in the persona of Duncan although semblances to that of someone in power or someone as the authority in the organization are manifested.These differences add up to the emphasis on the fact that Scotland, PA is no more than a remake of Shakespeare’s Macbeth although, apparently, the movie has its own unique sets of characters and settings in terms of specific roles and specific situational contexts. However, the general roles and situations in the murder scene both in the movie and in the play take us a step closer into the noticeable shades of likeness between the two.Moreover, these differences shed light on our understanding of the comparable elements in the movie and the play. As Scotland, PA has been filmed to reflect a more modern perception of the world in contrast to the high times of monarchy, Macbeth on the other hand has been specifically written so as to mirror th e context of the situation during the time it was written. These lead us to the understanding that, even though both works were years apart and even though the specific contexts upon which they operate are clearly defined by the society that the works replicate, there still remains an underlying correspondence between them through our comprehension of the general ideas involved in both works such as the plots of both Scotland, PA and Macbeth.The relationship that exists between the literary and the cinematic scenes can be summarized into the idea that the literary version of Macbeth reinforces the similar plot of the movie adaptation and that, conversely, the film reiterates the underlying themes in Macbeth. Both the literary and the movie murder scene correlate with one another inasmuch as one is to seek several parallel scenes that reinforce one from the other and conversely. It cannot be denied that the movie itself reflects in a large amount the general themes in the play and th at, correspondingly, the movie would have been entirely different or would not have been brought to the silver screens had it not been for Shakespeare’s Macbeth. Yet, it cannot also be denied that a modern translation of the play is clearly explicit in Scotland, PA thereby supporting the idea that a possible modern-day approach to the tragic play can be extracted from the movie, juxtaposing the elements of the literary work into the modern field of human comprehension.
