Thickness - Lab Report Example By methods for uprooting, the distinction in the underlying and last volumes of fluid utilized would be the volume dislodged through the strong item dove into the water, and, in this way, it fills in as the volume of the material itself. At this stage, given the mass, it might be estimated that the mass of pennies isolated by the volume uprooted or involved which causes ascend in the water level inside the graduated chamber respects the penny’s thickness. Techniques and Materials Type of Metal Used: Early-1985 penny with an acknowledged thickness estimation of 7.18 g/ml. At first, a 50-ml graduated chamber was loaded up with 20.00 ml of water, and it was deliberately recorded. The underlying mass of chamber and water (joined) was obtained utilizing a top-stacking parity and afterward recorded as starting perusing for the chamber balance arrangement. Pennies were dropped by additions of two where the new volume was perused and the new mass was estimated utilizing a similar adju sting hardware each time. This progression was done dully to make a sum of five informational collections, which incorporates taking note of conclusive volumes along and masses (seventh and eighth segments) through expansion of past contrasts with genuine volumes and masses, correspondingly. There were ten pennies dropped with everything taken into account, and so as to acquire the test estimation of thickness for each arrangement of pennies, the accompanying condition was applied: Density, ? = [ Mass(2) - Mass(1) ]/[ Volume(2) - Volume(1) ] (in g/ml) Results Initial Volume of Water (ml): 20.0 ml_ Initial Mass of Cylinder + Water: 105.06 g_ thickness, g/ml % contrast Rep A 5.03 29.94 Rep B 9.82 36.77 Rep C 10.06 40.11 Rep D 5.00 30.36 Rep E 9.98 39.00 Sample Calculations (utilizing Reps An and B of the table): Actual Volume = 21.5 ml - 21.0 ml = 0.5 ml Actual Mass = 115.0 g - 110.09 g = 4.91 g Density = Actual Mass/Actual Volume = 4.91 g/0.5 ml = 9.82 g/ml Final Volume = Actual V1 + Actual V2 = 1.0 ml + 0.5 ml = 1.5 ml Final Mass = Actual M1 + Actual M2 = 5.03 g + 4.91 g = 9.94 g Then utilizing the given hypothetical worth = 7.18 g/ml and the recipe % distinction = | 9.82 - 7.18 |/7.18 x 100% = 36.77% volume, ml mass, g 20 105.06 21 110.09 21.5 115 22 120.03 23 125.03 23.5 130.02 Based on the third and fourth sections of the principal table, starting with a volume (water) of 20.0 ml and a mass (chamber + water) of 105.06 g, the sums (volume and mass) of each succeeding line are deducted from the relating measures of the previous line to produce the fifth and sixth segment yields indicating real passages explicit for each two-penny increase. Since these densities give off an impression of being altogether unique when contrasted with the writing estimation of 7.18 g/ml, the normal thickness was evaluated from the diagram of mass versus volume of pennies. Considering the best-fit line drawn (by means of MS Excel program) reasonably between the plotted directions, the incline would be 7.186 g/ml as indicated by the subsequent condition m = 7.186v †39.36, with the goal that percent contrast rises to (7.186 - 7.18)/7.18 x 100% or 0.0836%, which is apparently lower than the % distinction comprehended independently, as appeared earlier. Conversation/Conclusion Though the results reflect conflicting estimations of thickness based on the real volumes and genuine masses which had been shown up at through the relocation strategy,

It is  used recreationally for its mild hallucinogenic and stimulant properties, as well as its ability to increase emotional closeness. MDMA is commonly known as ecstasy or molly, though what is referred to by these names is rarely purely MDMA. Rather, its often cut with other substances. MDMA is a Schedule I controlled substance, which means it has no established medical use and a high potential for misuse, although studies are underway to determine its effectiveness in treatment for anxiety in people with post-traumatic stress disorder (PTSD) and terminal illness. MDMA that is used recreationally isnt manufactured as a standard dose. It is made by illegal labs and packaged as tablets, capsules,  and powders of unknown strength and ingredients, to be snorted or taken orally. MDMA can be detected in your body from one to 90 days, depending on the type of test as well as the frequency of use and a persons unique physical characteristics. How Long Does MDMA Stay in Your System? Blood: Up to 2 daysUrine: Up to 4 daysSaliva: Up to 2 daysHair: Up to 90 days Ecstasy (MDMA): Everything You’ve Been Afraid to Ask How Long Does It Take to Feel Effects? MDMA works by boosting the activity of three neurotransmittersâ€"dopamine, serotonin, and norepinephrineâ€"that play a role in mood, energy level, appetite, trust, sexual activity, emotions, and sleep. People who use ecstasy typically feel the effects within 30 minutes of taking the drug and report feelings of euphoria, warmth, openness, and clarity as well as heightened sensations of touch, sound, and smell. These effects can last for three to six hours. MDMA is not a harmless drug. Serious risks include hyperthermia, cardiovascular effects, impaired mental capabilities, risky behavior, and overdose. Up to 24 hours after taking the drug, side effects include: NauseaVision problems (blurred vision or increased light sensitivity)Dry mouthMuscle cramping or tensionJaw and/or teeth clenching that is uncontrollableSweating After a week or more, users have reported the following side effects: IrritabilityImpulsiveness and aggressionDepressionSleep problemsAnxietyMemory and attention problemsDecreased appetiteDecreased interest in and pleasure from sex What Does MDMA Do to the Brain? How Long Does MDMA Last? While the recreational effects of MDMA  usually last about three to six hours, the half life of MDMA is 8 to 9 hours. As shown by one study, peak effects are observed between one and two hours and decrease four to 6 hours after taking the drug.?? MDMA is not one of the five drugs tested for by the standard five-panel drug test used by most employers; however, it does show up during this test. If MDMA shows up during the amphetamine test of the five-panel, a confirmation test will be run specifically looking for MDMA. Blood Research suggests that MDMA taken by mouth reaches its maximal blood concentration in about two hours. MDMA can be detected in blood for one to two days. Urine Ecstasy can be present for two to four days in urine. Hair Hair follicles maintain a trace of all drugs a person has taken, and MDMA is no exception. While hair drug tests are not common, be aware of the presence of MDMA in hair may linger for months. False Positive Testing Its always a good idea to tell the testing agency what other drugs and supplements you are taking so that the presence of these substances on your drug test results dont trigger a false positive. For example, a 2010 study found that the anti-depressant trazodone led to false positives on a commercial enzyme immunoassay test (Ecstasy EMIT II assay) for MDMA in urine.?? If any of the medications you are on trigger a false positive, stay calm and explain the medications you are taking and additional tests will be done to clear up the confusion. Snorting vs. Oral Ingestion How you take MDMA can impact detection time. In general, the faster the drug is absorbed into the bloodstream, the shorter the detection window.  For example, if you snort MDMA, it will stay in the body for a shorter amount of time than if you take it orally. Factors That Affect Detection Time Many factors can influence how a persons body processes or metabolizes MDMA, including the following. Dosage Frequency of Use If you take larger doses or take multiple doses over time, MDMA can stay in your system longer. Similarly, one-time users will have a shorter detection time than people who use the drug more often. Body Type Many drugs, or their metabolites, tend to accumulate in fatty tissues, so someone with a higher body mass index (BMI) may take longer to fully eliminate the drug from their body. Metabolism Some people may be fast or slow MDMA metabolizers. People with high metabolic rates, which are often affected by age, activity level, and certain health conditions, tend to have a smaller detection window. Overall Health Underlying health problems, such as liver or kidney disease, can influence drug metabolism. How to Get MDMA Out of Your System Contrary to popular belief, drinking a lot of water will not flush your system of MDMA to help beat a drug test. This practice is not only ineffective but its dangerous during the first 12 hours after taking the drug since MDMA can exacerbate the effects of drinking too much water. The only way to get MDMA out of your system is to stop taking the drug and allow your body time to metabolize and eliminate it. Symptoms of Overdose People who take MDMA may try to take more of the drug as the high begins to wear off, while the first dose is still in their system. They may think they arent feeling anything, end up taking more, and then get hit with a larger dose than they bargained for, which can lead to an accidental overdose. The following are some symptoms of an MDMA overdose: High blood pressureFeeling faintPanic attacksLoss of consciousnessSeizures Dangerous Interactions Using other drugs or alcohol with MDMA increases the risk of overdose. Its important to note that any additional substances cut into MDMA will also have their own set of effects and influence how long the drug stays in your system. MDMA can temporarily impede the bodys ability to regulate temperature. Extreme spikes in body temperature can result in heart, kidney, or liver failure and even death. While no adverse event related to this has been documented in controlled, clinical environments, this effect is believed to be a problem in club environments, where people may be dancing and not drinking enough water. Well-intentioned narratives about it being extra important to drink water on MDMA can backfire when people begin to drink more water than they need. As a 2016 study showed, MDMA can increase water retention and increase the risk of water toxicity, or hyponatremia, if too much water is ingested.?? Symptoms of hyponatremia include nausea, confusion, fatigue, irritability, muscle spasms, and seizures. If you suspect someone has overdosed or is having a negative reaction to MDMA, call 911 immediately. How to Recognize the Signs of Ecstasy Use in Teens Getting Help Symptoms of withdrawal can range from mild to severe, depending on the frequency of use and dependency, and can sometimes cause people to return to using MDMA or another drug to avoid these unpleasant effects. Symptoms of MDMA withdrawal include: AnxietyConfusionInsomniaPoor memoryFatigueDifficulty concentratingDepression If you are concerned about having a positive drug test and want to stop using MDMA, help is available. With help, you can learn how to stop using the drug and better cope with any symptoms of withdrawal so you can begin on the road to recovery.

The Misogynistic Henry Higgins - 1990 Words

The Misogynistic Henry Higgins The key to understanding George Bernard Shaw’s Pygmalion lies in understanding the power struggle between the â€Å"haves† and â€Å"have-nots† – specifically the active and intentional disenfranchisement of women at the turn of the 20th century. At the core of Pygmalion there is a focus on the societal inequities of the day, with Shaw presenting society’s treatment of women as property without rights and with little understanding of their surroundings or place in society. Throughout the 19th century, and into the early 20th century, when Shaw penned Pygmalion, British laws and society actively restrained women, both politically and economically. Unlike the United States, women in England were allowed to vote prior†¦show more content†¦Much of English society and government mirrored Higgins beliefs. In 1888, an appeals court judge, Lord Esther, ruled that â€Å"neither by Common Law nor by the Constitution of this country from the beginning of the Common Law until now can a woman be entitled to exercise any public function.† (Aked) This is notable because, just as with the Reform Act of 1832, the ruling was a detriment to women, as women were already â€Å"exercising public functions†, such as overseers, way-wardens, church-wardens and members of school boards. This ruling was the first of several rulings and legislations that removed rights and governmental access from women. These actions of the British Parliament led to the creation of several suffrage movement organizations in England, such as the Co-operative Society and The Labor Party, each with almost two and a half million members, as well as several smaller groups, such as The Women’s Liberal Association, The British Women’s Temperance Association, The Women’s Textile Union, The Women’s Labor League, The National Union of Women’s Suffrage Societies, The Women’s Social and Political Union, and The Men’s League for Woman Suffrage, as well as many others. It is well known that Shaw was an avid proponent of womens freedom and suffrage, and it is quite possible that Shaw wrote Pygmalion with the idea of promoting women’s suffrage as, only three years earlier, he had already penned aShow MoreRelatedThe Progression Of The Role Of Women2180 Words   |  9 Pages‘womanly’ again.

Dawnette’s Havard-Hosted Implicit Association Test Free Essays

My test result from the Skin-Tone Test is that I have a preference for Light Skinned people rather than Dark Skin. This proved to be somewhat correct. When I was younger all I wanted was a light-skinned boyfriend. We will write a custom essay sample on Dawnette’s Havard-Hosted Implicit Association Test or any similar topic only for you Order Now I did have many light-skinned guys that would be very bold in wanting to get to know me in my past and even in my present. I do feel that the results were somewhat valid. The reason that I say somewhat valid is because I do not mind what color the person is on the outside. I get along with all race, creed, and color of people. It did make me think back to when I see a guy, who I usually go â€Å"Oooh-wee† over. Most of the time, the guy is usually lighter than I am. I guess I was stuck on the skin tone for so long that it is still very much a part of me. When I think about is it seems that it is just nature, because I do see many darker skinned individuals gravitating towards lighter-skinned people. I often wonder is that an instinct in us or solely a personal preference? My opinion is that it is difficult to accurately measure prejudice. Most people will not admit on a test or even in person that they think negatively of them due to their skin color. That fact alone makes it very difficult to measure prejudices amongst people. There are two major ways to categorize the measurements which sociologists calculate prejudice. One is through stratification by class and gender. The other is through several theoretical perspectives, such as: * Functional perspectives * Conflict perspectives * Labeling theory approaches The functional perspective looks at things like dysfunction. The conflict perspective deals with things like blaming the victim. The labeling theory approaches utilizes things like the self-fulfilling prophecy.

The Chambered Nautilus Essay, Research Paper CHAMBERED Nautilus ( NAUTILUS POMPILIUS ) STEVEN HEGARTY CHAMBERED NAUTILUS L. KOCH MARINE SCIENCE 12/21/99 Hegarty 1 The chambered nuclear submarine is a cephalopod, which besides includes calamari, octopus, and cuttlefish, which belongs to mollusca. There are several species of the nuclear submarine, which include Allonautilus scrobiculatus, Nautilus belauensis, Nautilus macromphalus, Nautilus pompilius, Nautilus repertus, and Nautilus stenomphalus. The nuclear submarine is found in merely a 15degree set near the equator in the Pacific Ocean. ( soest ) The nuclear submarine has been around for over 500 million old ages, and has changed at all. It was one time one of the many different sorts of shelled cephalopods, but now is the lone one left. ( all resources ) The nautilus scopes from 500 to 1000 ft. under the ocean along reef inclines and walls. Nautiluss are scavengers feeding largely on crustaceans. Nautiluss live so deep because if they deeper than 800m there shells will go off and at 500m there shells will deluge. We will write a custom essay sample on The Chambered Nautilus Essay Research Paper CHAMBERED or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Nautiluss prefer H2O temperatures of around 21degrees C, that is another ground they live so deep. ( ozeman ) At dark the nuclear submarines rise to the deepness of 100 to 200 ft. to eat, though they are non nocturnal. This is the lone clip scientists have been able to analyze the nuclear submarine in it s natural home ground, and yet they still have to pin down them to detect them. The scientists use a trap, made out of either mesh or plastic, with a 12 hole in it. The trap is baited with fish or even sometimes even chicken. The scientists let the net set for the dark and draw it up the following forenoon to recover the gimmick. Due to the fact that the Chamberss in the nautilus s shell are filled with air, the animate being is unhurt when brought to the surface. ( underwater ) Hegarty 1 Nautiluss spend a batch of their clip rolling the underside. They propel themselves with a flexible tubing like jet. This jet can be directed at any angle to maneuver themselves around the reef. ( underwater ) Above its jet the nuclear submarine has a beaked oral cavity, like tha T of other cephalopods. Around the oral cavity there are 80 to 100 really gluey tentacles, which enables the nuclear submarine to draw nutrient closer to it s oral cavity, such as the molted skeleton of spiny or slipper lobster. The full organic structure of this animal is located in the first chamber of the shell. When threatened the nautilus screens it s full organic structure with a tough flexible covering. ( submerged ) . The nautilus needs this sort of protection from animals like triggerfish, sea polo-necks, and sharks. ( Mrs. Koch ) The shell of the nuclear submarine is alone in which the interior is riddled with Chamberss ( 38 Chamberss ) . The nautilus uses these Chamberss to travel itself up and down in the H2O column. Even though the shell resembles that of a snail, the nuclear submarine is more closely related to the cephalopods. This form helps the nuclear submarine from being crushed under the tremendous force per unit area. ( Mrs. Koch ) Nautiluss can turn to every bit much as 12 in diameter and weigh 2 pound. The nautilus doesn T reach sexual adulthood until 15 to 20 old ages of age. Unlike other cephalopods, the nautilus lives after reproduction. Scientists re non certain as to how old nuclear submarines get to be. The nuclear submarines lay 1 + long eggs, which hatch into babes an 1 in diameter. ( Mrs. Koch ) The shells of the nuclear submarines have long been prized by worlds for their natural beauty. In the Tanon Strait of the Philippines the hole nautilus population has been wiped out because of over fishing and the fact it takes so long for nuclear submarines to make sexual adulthood.
