Percentage of women’s The percentages of women who are affected by drugs nationwide is 21.5 million, 3.5 million misuse prescription drugs and 3.1 million report regularly using illicit drugs. Mostly half of the women’s of ages 15-44 have used drugs at least once in their lifetime. Two millions use cocaine, sex million used marijuana and four million who used prescription drugs non-medically. Ages 12-17 years old, females exceed males in the use of cigarettes, cocaine, crack, inhalants and prescription drugs for non-medical reasons. Females have less muscle tissue than men and the enzymes that metabolize alcohol are less effect in women. Every year 140,000 women die from smoking. B.

Elephant Toothpaste Chemistry Demonstration

The dramatic elephant toothpaste chemistry demonstration produces copious amounts of steaming foam that looks like the kind of toothpaste an elephant might use to brush his tusks. To see how to set up this demo and learn the science of the reaction behind it, read on. Elephant Toothpaste Materials The chemical reaction in this demonstration is between the hydrogen peroxide and a solution of potassium iodide and dishwashing detergent that captures the gases to make bubbles. 50-100 ml of 30% hydrogen peroxide (H2O2) solution (Note: This hydrogen peroxide solution is much more concentrated than the kind youd generally purchase at a pharmacy. You can find 30% peroxide at a beauty supply store, science supply store, or online.)Saturated potassium iodide (KI) solutionLiquid dishwashing detergentFood coloring500 mL graduated cylinderSplint (optional) Safety For this demonstration, its advisable to wear disposable gloves and safety glasses. Since oxygen is involved in this reaction, do not perform this demonstration near an open flame. Also, the reaction is exothermic, producing a fair amount of heat, so do not lean over the graduated cylinder when the solutions are mixed. Leave your gloves on following the demonstration to aid with cleanup. The solution and foam may be rinsed down the drain with water. Elephant Toothpaste Procedure Put on gloves and safety glasses. The iodine from the reaction may stain surfaces so you might want to cover your workspace with an open garbage bag or a layer of paper towels.Pour ~50 mL of 30% hydrogen peroxide solution into the graduated cylinder.Squirt in a little dishwashing detergent and swirl it around.You can place 5-10 drops of food coloring along the wall of the cylinder to make the foam resemble striped toothpaste.Add ~10 mL of potassium iodide solution. Do not lean over the cylinder when you do this, as the reaction is very vigorous and you may get splashed or possibly burned by steam.You may touch a glowing splint to the foam to relight it, indicating the presence of oxygen. Variations of the Elephant Toothpaste Demonstration You can add 5 grams of starch to the hydrogen peroxide. When the potassium iodide is added, the resulting foam will have light and dark patches from the reaction of some of the starch to form triiodide.You can use yeast instead of potassium iodide. Foam is produced more slowly, but you can add a fluorescent dye to this reaction to produce elephant toothpaste that will glow very brightly under a black light.You can color the demonstration and make it into an Elephant Toothpaste Christmas Tree for the holidays.Theres also a kid-friendly version of the elephant toothpaste demo thats safe for little hands. Elephant Toothpaste Chemistry The overall equation for this reaction is: 2 H2O2(aq) → 2 H2O(l) O2(g) However, the decomposition of the hydrogen peroxide into water and oxygen is catalyzed by the iodide ion. H2O2(aq) I-(aq) → OI-(aq) H2O(l) H2O2(aq) OI-(aq) → I-(aq) H2O(l) O2(g) The dishwashing detergent captures the oxygen as bubbles. Food coloring can color the foam. The heat from this exothermic reaction is such that the foam may steam. If the demonstration is performed using a plastic bottle, you can expect a slight distortion of the bottle due to the heat. Elephant Toothpaste Experiment Fast Facts Materials: 30% hydrogen peroxide, concentrated potassium iodide solution or a packet of dry yeast, liquid dishwashing detergent, food coloring (optional), starch (optional)Concepts Illustrated: This demonstration illustrates exothermic reactions, chemical changes, catalysis, and decomposition reactions. Usually, the demo is performed less to discuss the chemistry and more to raise interest in chemistry. It is one of the easiest and most dramatic chemistry demonstrations available.Time Required: The reaction is instantaneous. Set-up can be completed in under half an hour.Level: The demonstration is suitable for all age groups, particularly to raise interest in science and chemical reactions. Because the hydrogen peroxide is a strong oxidizer and because heat is generated by the reaction, the demonstration is best performed by an experienced science teacher. It should not be performed by unsupervised children.

Discuss the ways in which women’s domestic role Free Essays

Beginning in the home, a woman’s role is socially constructed from an early age. A woman’s role models are traditionally her parents and many women naturally follow in their mothers footsteps. However, this can often work In reverse and women of whose mothers stayed at home In a domestic care role then go on to carve careers for themselves. We will write a custom essay sample on Discuss the ways in which women’s domestic role or any similar topic only for you Order Now Although these days women do have careers they are still socially seen as the homemaker regardless of this. A woman’s domestic role is often run alongside other work and a great number of women choose careers which are care eased. The sexual division of labor is at the heart of gender inequality, which is underpinned by the patriarchal family structure where the man Is the highest authority and sole provider and there Is a rolled dolls of tasks and responsibilities, all of which have been regulated by social norms that have become constructed and ingrained over time. Florence Nightingale was a great influence in creating the nursing/caring role. She acknowledged that a great number of women naturally progressed into care roles and so she introduced the role of a nurse yet it was not a consider profession at this point Medical stations in the Crimean war were poorly staffed with awful medical and sanitary conditions. This was reported by the media In Britain. Florence Nightingale, one of 38 voluntary nurses traveled to Turkey to help relieve the situation. Nightingale worked towards improvements in sanitation, nutrition, and activity for the patients of the hospitals. Death rates were reduced dramatically with the introduction of such measures. Nightingale kept meticulous records of the number of deaths, and the causes of deaths, so that on her return to Great Britain she could Justify the need for Improving conditions In hospitals. Criticisms of Florence Nightingale have been that she created a female occupation, excluding males based around her view that women were naturally caring and naturally gifted at looking after people. This only emphasized ‘female virtues’ especially in the media as they made this her main point even though there was much more to her than Just this point. As a result of what she did the beliefs of the male professionals were further supported. Those beliefs being that women are innate males in the workforce and the nursing role was stereotyped as a role which only women performed bringing with It the stereotype which we still hold today. Even now, with many more men taking on the role of the nurse we seem to find this unusual and sometimes quite a surprise. During this time the education system excluded women from the ability to gain scientific knowledge and the medical profession denied access to women who actually had managed to gain education. After Florence Nightingale, Ethel Bedford Fenwick (who is she) said that by 1901 , although we had moved on from the workhouses there was still no professional nurses in Britain and campaigned for a nationally recognized training system to create an actual nursing ‘profession’ This era was such named the era of the ministering angel’ She worked to elevate nursing from the time of Florence Nightingale. During much of the 20th Century there was little progress with the imbalance of male to female care professions, even with the introduction of the INS women still made up the majority of the workforce in the INS with the male professions making up the majority of top rank Jobs, such as surgeons and insulates, much higher paid, recognized and respected professions. Domestic service of all kinds was the single largest employer of women (40 per cent of female occupations stated in the census of 1851 in provincial cities and 50 per cent in London). The textile and clothing sectors came a close second (http:// www. BBC. Co. UK/history/British/Victorians/women’s_work_OLL . SHTML) A greater number of women than men choose Job roles in the care industry. Ann Oakley refers to this as being the influence of gender oscillation and the women’s domestic role in the home throughout history. This fact adds to the divide between men and women in the health and social care sector with statistics showing that in 2010 for an example, women made up 74% of the workforce in the INS and men only 26%. Even the most educated women earn less than men, women generally receive a lower return on their education and workplace discrimination against women is reflected in pay irrespective of educational level. In 2009 the BAM report was released, highlighting the inequality in male and female salaries within the health care industry. An average gap of El 5,245 between men and women in the same reversions. â€Å"Our results show that men and women with identical experience and expertise are paid differently – which suggests evidence of discrimination† (BAM 2009) It seems women are discriminated against due to her weakness in her ability to move.

Weather Computing essays

Weather Computing essays Weather forecasting has been an important application area over the past 100 years. The complex numerical calculations and modeling structures that have been developed, require a fairly sophisticated level of technological development. Prior to the advent of digital computers it was practically impossible to forecast the weather. As technology progressed, so did the theoretical models, leading to increases in detail and accuracy levels of weather forecasting. The first steps in scientific weather forecasting The numerical models had been developed by Lewis Fry Richardson, who used basic equations of motion and state to model atmospheric dynamics. The data sets in the model included that barometric pressure and wind speed for a particular region. In 1922 he published Weather Prediction by Arithmetic Finite Differences which demonstrated the correlation of mathematics and the weather. Essentially the model would simulate the evolution of weather patterns. The computational power needed to carry out the calculations involved some 64000 people armed with slide rules and mechanical calculators. Each member would carry out parts of the calculation; telegraph and flashing coloured lights would transmit results. Despite the huge efforts exerted, weather could only be calculated only as fast at it was happening and results were incorrect. This stemmed from lack of computational power and the lack of meteorological data. Richardsons equations worked by separating regions into areas of a specific size. The calculations performed in each area would be combined to form the weather forecast. In order to obtain more accurate readings, the separated regions have to be reduced in size. However this meant that more data and computational power would be needed (the ability to obtain both of were lacking at the time). In figure 1 we see Locations of meteorological stations from which Richardson obtained upper-air observations...

Lines and Slopes ACT Math Geometry Review and Practice

Lines and Slopes ACT Math Geometry Review and Practice SAT / ACT Prep Online Guides and Tips You’ve dealt with the basics of coordinate geometry and points (and if you haven’t already, you may want to take a minute to refresh yourself) and now it’s time to look at the ins and outs of lines and slopes on the coordinate plane. This will be your complete guide to lines and slopeswhat slopes mean, how to find them, and how to solve the many types of slope and line equation questions you’ll see on the ACT. What are Lines and Slopes? If you’ve gone through the guide on coordinate geometry, then you know that coordinate geometry takes place in the space where the $x$-axis and the $y$-axis meet. Any point on this space is given a coordinate point, written as $(x, y)$, that indicates exactly where the point is along each axis. A line (or line segment) is a marker that is completely straight (meaning it has no curvature). It is made up of a series of points and and connects them together. A slope is how we measure the slant/steepness of a line. A slope is found by finding the change in distance along the y axis over the change in distance along the x axis. You have probably heard how to find a slope by finding the "rise over run." This means exactly the same thingchange in $y$ over change in $x$. $${\change \in y}/{\change \in x}$$ Let's look at an example: Say we are given this graph and asked to find the slope of the line. We must see how both the rise and the run change. To do this, we must first mark points along the line to in order to compare them to one another. We can also make life easier on ourselves by marking and comparing integer coordinates (places where the line hits at a corner of $x$ and $y$ measurements.) Now we have marked our coordinate points. We can see that our line hits at exactly: $(-3, 5)$, $(1, 0)$, and $(5, -5)$. In order to find the slope of the line, we can simply trace our points to one another and count. We've highlighted in red the path from one coordinate point to the next. You can see that the slope falls (has a negative "rise") of 5. This means the rise will be -5. The slope also moves positively (to the right) 4. Thus, the run will be +4. This means our slope is: $-{5/4}$ Properties of Slopes A slope can either be positive or negative. A positive slope rises from left to right. A negative slope falls from left to right. A straight line has a slope of zero. It will be defined by one axis only. $x = 3$ $y = 3$ The steeper the line, the larger the slope. The blue line is steepest, with a slope of $3/2$. The red line is shallower, with a slope of $2/5$ Now that we've gone through our definitions, let us take a look at our slope formulas. Line and Slope Formulas Finding the Slope $${y_2 - y_1}/{x_2 - x_1}$$ In order to find the slope of a line that connects two points, you must find the change in the y-values over the change in the x-values. Note: It does not matter which points you assign as $(x_1, y_1)$ and $(x_2, y_2)$, so long as you keep them consistent. Find the slope of the line with coordinates at (-1, 0) and (1, 3). Now, we already know how to count to find our slope, so let us use our equation this time. ${y_2 - y_1}/{x_2 - x_1}$ Let us assign the coordinate (-1, 0) as $(x_1, y_1)$ and (1, 3) as $(x_2, y_2)$. $(3 - 0)/(1 - -1)$ $3/2$ We have found the slope of the line. Now let's demonstrate why the equation still works had we switched which coordinate points were $(x_1, y_1)$ and which were $(x_2, y_2)$. This time, coordinates (-1, 0) will be our $(x_2, y_2)$ and coordinates (1, 3) will be our $(x_1, y_1)$. ${y_2 - y_1}/{x_2 - x_1}$ $(0 - 3)/(-1 - 1)$ ${-3}/{-2}$ $3/2$ As you can see, we get the answer $3/2$ as the slope of our line either way. The Equation of a Line $$y = mx + b$$ This is called the â€Å"equation of a line,† also known as an line written in "slope-intercept form." It tells us exactly how a line is positioned along the x and y axis as well as how steep it is. This is the most important formula you’ll need when it comes to lines and slopes, so let’s break it into its individual parts. $y$ is your $y$-coordinate value for any particular value of $x$. $x$ is your $x$-coordinate value for any particular value of $y$. $m$ is the measure of your slope. $b$ is the $y$-intercept value of your line. This means that it is the value along the $y$-axis that the line hits (remember, a straight line will only hit each axis a maximum of one time). For this line, we can see that the y-intercept is 3. We can also count our slope out or use two sets of coordinate points (for example, $(-3, 1)$ and $(0, 3)$) to find our slope of $2/3$. So when we put that together, we can find the equation of our line at: $y = mx + b$ $y = {2/3}x + 3$ Remember: always re-write any line equations you are given into this form! The test will often try to trip you up by presenting you with a line NOT in proper form and then ask you for the slope or y-intercept. This is to test you on how well you're paying attention and get people who are going too quickly through the test to make a mistake. What is the slope of the line $3x + 12y = 24$? First, let us re-write our problem into proper form: $y = mx + b$ $3x + 12y = 24$ $12y = -3x + 24$ $y = -{3/12}x + 24/12$ $y = -{1/4}x + 2$ The slope of the line is $-{1/4}x$ Now let’s look at a problem that puts both formulas to work. For some real number A, the graph of the line $y=(A+1)x +8$ in the standard $(x,y)$ coordinate plane passes through $(2,6)$. What is the slope of this line? A. -4B. -3C. -1D. 3E. 7 In order to find the slope of a line, we need two sets of coordinates so that we can compare the changes in both $x$ and $y$. We are given one set of coordinates at $(2, 6)$ and we can find the other by using the $y$-intercept. The $b$ in the equation is the y-intercept (in other words, the point at the graph where the line hits the y-axis at $x = 0$). This means that, for the above equation, we also have a set of coordinates at $(0, 8)$. Now, let’s use both sets of coordinates- $(2, 6)$ and $(0, 8)$- to find the slope of the line: ${y_2 - y_1}/{x_2 - x_1}$ $(8 - 6)/(0 - 2)$ $-{2/2}$ $-1$ So the slope of the line is -1. Our final answer is C, -1. (Note: don’t let yourself get tricked into trying to find $A$! It can become instinct when working through a standardized test to try to find the variables, but this question only asked for the slope. Always pay close attention to what is being asked of you.) Perpendicular Lines Two lines that meet at right angles are called â€Å"perpendicular.† Perpendicular lines will always have slopes that are negative reciprocals of one another. This means that you must reverse both the sign of the slope as well as the fraction. For example, if a two lines are perpendicular to one another and one has a slope of 4 (in other words, $4/1$), the other line will have a slope of $-{1/4}$. Parallel Lines Two lines that will never meet (no matter how infinitely long they extend) are said to be parallel. This means that they are continuously equidistant from one another. Parallel lines have the same slope. You can see why this makes sense, since the rise over run will always have to be the same in order to ensure that the lines will never touch. No matter how far they extend, these lines will never intersect. What is the slope of any line parallel to the line $8x+9y=3$ in the standard $(x,y)$ coordinate plane? F. -8G. $-{8/9}$H. $8/3$J. 3K. 8 First, let us re-write our equation into proper slope-intercept equation form. $8x + 9y = 3$ $9y = -8x + 3$ $y = -{8/9} + 1/3$ Now, we can identify our slope as $-{8/9}$. We also know that parallel lines have identical slopes. So all lines parallel to this one will have the slope of $-{8/9}$. Our final answer is G, $-{8/9}$. A...valiant attempt to be parallel. Typical Line and Slope Questions Most line and slope questions on the ACT are quite basic at their core. You’ll generally see two to three questions on slopes per test and almost all of them will simply ask you to find the slope of a line when given coordinate points or intercepts. The test may attempt to complicate the question by using other shapes or figures, but the questions always boil down to these simple concepts. Just remember to re-write any given equations into the proper slope-intercept form and keep in mind your rules for finding slopes (as well as your rules for parallel or perpendicular lines), and you’ll be able to solve these types of problems easily. What is the slope of the line through $(5,-2)$ and $(6,7)$ in the standard $(x,y)$ coordinate plane? F. $9$G. $5$H. $-5$J. $5/11$K. $-{5/11}$ We have two sets of coordinates, which is all we need in order to find the slope of the line which connects them. So let us plug these coordinates into our slope equation: ${y_2 - y_1}/{x_2 - x_1}$ $(7 - 2)/(6 - -5)$ $5/11$ Our final answer is J, $5/11$ Despite the fact that we are now working with figures, the principle behind the problem remains the samewe are given a set of coordinate points and we must find their slope. From C to D, we have coordinates (9, 4) and (12, 1). So let us plug these numbers into our slope formula: ${y_2 - y_1}/{x_2 - x_1}$ $(1 - 4)/(12 - 9)$ $-3/3$ $-1$ Our final answer is B, $-1$. As you can see, there is not a lot of variation in ACT question on slopes. So long as you keep track of the coordinates you’ve assigned as $(x_1, y_1)$ and $(x_2, y_2)$, and you make sure to keep track of your negatives and positives, these questions should be fairly straightforward. How to Solve a Line and Slope Problem As you go through your line and slope problems, keep in mind these tips: #1: Always rearrange your equation into $y = mx + b$ If you are given an equation of a line on the test, it will often be in improper form (for example: $10y + 15x = 20$). If you are going too quickly through the test or if you forget to rearrange the given equation into proper slope-intercept form, you will misidentify the slope and/or the y-intercept of the line. So always remember to rearrange your equation into proper form as your first step. $10y + 15x = 20$ = $y = -{3/2}x + 2$ #2: Remember your $\rise/\run$ Our brains are used to doing things "in order," so it can be easy to make a mistake and try to find the change in $x$ before finding the change in $y$. Keep careful track of your variables in order to reduce careless mistakes like this. Remember the mantra of "rise over run" and this will help you always know to find your change in $y$ (vertical distance) over your change in $x$ (horizontal distance). #3: Make your own graph and/or count to find your slope Because the slope is always "rise over run," you can always find the slope with a graph, whether you are provided with one or if you have to make your own. This will help you better visualize the problem and avoid errors. If you forget your formulas (or simply don't want to use them), simply draw your own graph and count how the line rises (or falls). Next, trace its "run." By doing this, you will always find your slope. Now let's put your newfound knowledge to the test! Test Your Knowledge Now that we’ve walked through the typical slope questions you’ll see on the test (and the few basics you’ll need to solve them, let’s look at a few real ACT math examples: 1. 2. Which of the following is the slope of a line parallel to the line $y={2/3}x-4$ in the standard $(x,y)$ coordinate plane? A. $-4$B. $-{3/2}$C. $2$D. $3/2$E. $2/3$ 3. When graphed in the standard $(x,y)$ coordinate plane, the lines $x=-3$ and $y=x-3$ intersect at what point? A. $(0,0)$B. $(0,-3)$C. $(-3,0)$D. $(-3,-3)$E. $(-3,-6)$ Answers: D, E, E Answer Explanations: 1. You can solve this problem in one of two waysby counting directly on the graph, or by solving for the changes in $x$ and $y$ algebraically. Let’s look at both methods. Method 1- Graph Counting The question was generous in that it provided us with a clearly marked graph. We also know that our slope is $-{2/3}$, which means that we must either move down 2 and over 3 to the right, or up 2 and over 3 to the left to keep our movement across a negative slope line consistent. If you use this criteria to count along the graph, you will find that you hit no marked points by counting up 2 and over 3 to the left, but you will hit D when you go down 2 and over 3 to the right. So our final answer is D. Method 2- Algebra Alternatively, you can always use your slope formula to find the missing coordinate points. If we start with our coordinate points of $(2, 5)$ and our slope of $-{2/3}$, we can find our next two coordinate points by counting finding the changes in our $x$ and $y$. Our first coordinate point of $(2, 5)$ has a $y$ value of 5. We know, based on the slope of the line that the change in $y$ is +/- 2. So our next coordinate point must have a $y$ value of either: $5 + 2 = 7$ Or $5 - 2 = 3$ This means we can eliminate answer choices B and C. Now we can do the same for our x-coordinate value. We begin with $(2, 5)$, so our $x$ value is 2. Because the line has a slope of $-{2/3}$, our x-coordinate change at a rate of +/- 3. This means our next x-coordinate values must be either: $2 + 3 = 5$ Or $2 - 3 = -1$ Now, we must put this information together. Because our slope is negative, it means that whatever change one coordinate undergoes, the other coordinate must undergo the opposite. So if we are adding the change in $y$, we must then subtract our change in $x$ (or vice versa). This means that our coordinate points will either be $(5, 3)$ or $(-1, 7)$. (Why? Because 5 comes from adding our change in $x$ and 3 comes from subtracting our change in $y$, and -1 comes from subtracting our change in $x$ and 7 comes from adding our change in $y$.) The only coordinates that match are at D, $(5, 3)$. Our final answer is D. 2. This question is simple so long as we remember that parallel lines have the same slopes and we know how to identify the slope of an equation of a line. Our line is already written in proper slope-intercept form, so we can simply say that the line $y = {2/3}x - 4$ has a slope of $2/3$, which means that any parallel line will also have a slope of $2/3$. Our final answer is E, $2/3$ 3. This question may seem confusing if you’ve never seen anything like it before. It is however, a combination of a simple replacement in addition to coordinate points. We are given that $x = -3$ and $y = x - 3$, so let us replace our $x$ value in the second equation to find a numerical answer for $y$. $y = x - 3$ $y = -3 - 3$ $y = -6$ Which means that the two lines will intersect at $(-3, -6)$. Our final answer is E, $(-3, -6)$. A good test deserves a good break, don't you think? The Take-Aways Though the ACT may present you with slightly different variations on questions about lines and slopes, these types of questions will always boil down to a few key concepts. Once you've gotten the hang of finding slopes, you'll be able to breeze through these questions in no time. Make sure to keep track of your negatives and positives and remember your formulas, and you’ll be able to take on these kinds of questions with greater ease than ever before. What’s Next? Whew!

Trace the complex seemingly contradictory relationship between the Essay

Trace the complex seemingly contradictory relationship between the exotic 'newness' of primitivism and the urge to explore ethnic or national roots - Essay Example The canvas included portraits, still lifes, landscape, verve, nudes of spontaneity with rich textured surfaces, bold colors and lively linear patterns. The Fauves used startling contrasts of emerald green, vermilion, vivid orange and cerulean blue in bold strokes and sweeping brush strokes. Fauves desired to use both sides of Expressionism. Outward expression was expressed in the bold release of internal thoughts in wild color, brutal and powerful brushworks and the depiction of inward expression awakened the emotion of the viewers through the designs. There was no official organization of Fauve painters. The laxity of stylistic affinities and personal connections led the Fauve movement to disintegrate as soon as the art form emerged. The artists who followed Fauve principles departed from the idea and followed their own personal styles. The short tenure of Fauvism however made remarkable contribution to the art of painting by experimenting expressive, structural and aesthetic capabi lities. Henri Matisse was a prominent figure among the Fauve group.1 German Expressionism evolved from Fauvism and moved beyond the art in compelling, dramatic portrayal of people and scenes. Three main groups of German Expressionism were Die Brucke, Der Blaue Reiter and Die Neue Sachlichkeit. Der Blaue Reiter  or the Blue Rider group took shape in Munich which is home of avant-garde New Artist Association. The most famous artist of Der Blaue Reiter was Wassily Kandinsky and Franz Marc. Der Blaue Reiter was a loose association with artists like Paul Klee, August Macke and Gabriele Munter. The objective of the Blue Rider was to infuse art with spiritual values with the use of color. Blue riders mean vague. Marc instilled the idea that animal had innocence and so it is superior to human. The Blue Rider Expressions are mild forms which are seen in Cossacks by Kandinsky, Little Blue Horse and The Little Blue Horses by
