Example of a Research Plan Essay Statement of the Problem The aim of the study is to identify the effect of different pH level of the Agar plate to the antibacterial activity of Santol (Sandoricum koet jape). Specifically, the study will seek for the answer of the question: 1.) Is there any difference on the No.of colonies after applying Santol (Sandoricum koet jape) extract on the Agar plate with pH level greater than seven (base)? 2.) Is there any difference on the No.of colonies after applying Santol (Sandoricum koet jape) extract on the Agar plate with pH level less than seven (acid)? Hypothesis 1.) There is no difference on the No.of colonies after applying Santol (Sandoricum koet jape) extract on the Agar plate with pH level greater than seven (base). 2.) There is difference on the No.of colonies after applying Santol (Sandoricum koet jape) extract on the Agar plate with pH level less than seven (acid). Research Methodology Materials and Equipment The study will make use of: Agar Plates, specifically Nutrient Agar, for different tests and as a controlled variable for the problem, Nutrient Broth, same purpose as the nutrient agar, Santol (Sandoricum koet jape) extract, Escherichia coli, for the gram positive, Bacillus , for gram negative, and Candida________ a test subject for the study. Also, the study will make use of litmus paper for measuring and maintining the pH level of the Agar plates. The study will also make use of spectrophotometry. Research Design The study will use Complete Randomized Design as a Research Design. Â  Control Group Design is two parallel experiments are set up, identical in all respects except that only one includes the treatment being explored by the experiment. The control group may have no treatment, with nothing happening to them, or they may have a neutral treatment. Statistical Tool The study will make use of ANOVA as its statistical tool. T-test can be use to compare two dependent samples/matched-pairs design experiments. The study will make use of two types of pH: Acidic and Basic. Each Agar Plate will be assign to one specific pH level. Inoculate the microbes in the Agar and in the broth. This can be done by streaking the loop containing the gram positive, gram negative, and the fungi . Data Gathering Procedure Prepare the Agar plate and the broth for the experimentation. The pH of the Agar and the broth must also be set. Place the agar filled petri dishes and the broth that have been inoculated in a dark, warm (86 F) place for a week for incubation. Apply the extract of Santol (Sandoricum koet jape) to each Agar plate and Nutrient Broth. Using the Colony Formation Unit (CFU), determine the number of colony inhibited. Record the data from the Agar plates and the Nutrient broth. Figure 3.1 Experimental Procedures Figure 3.1 Experimental Procedures shows the step by step procedure of the experiment. Starting from the preparation of the Agar plate with their assign pH level. The Agar plate will solidify at 32Â ºC- 40Â ºC but will melt at approximately 85Â ºC. Next is to inoculate the bacteria by streaking the loop containing the bacteria. After inoculating the bacteria, the agar plate must be incubated for one week. After the incubation of the agar plates, apply the Santol (Sandoricum koet jape) extract to the each agar plate. Each plate must receive equal amount of the extract. Using the Colony Formation Unit (CFU), determine the number of inhibited colony/ies and record the data.

Promotion and Retention of Women in Mathematics :: Mathematical Careers Education Essays

Promotion and Retention of Women in Mathematics How do we interest and retain more women in the field of mathematics? "Women now make up nearly half the undergraduate math majors in the U.S. (1993 Annual Survey of the American Mathematical Society and the Mathematical association of America); yet in graduate math programs, only about one-quarter of the American students are women" (Adhikari & Nolan, 1997, p. 17). For women who choose SME (Science, Mathematics, Engineering) majors, persistence rates in the major are significantly lower than that of male peers. (Seymour, 1995, p. 438) I am interested in the topic because I am a female who experienced pursuing undergraduate and graduate mathematics degrees. I want to know what I can do to help motivate other women in mathematics. While reading the literature, I became aware of subtle personal experiences that paralleled common experiences of women pursuing mathematics majors. Whereas I had informally considered my attempts at fair, consistent treatment for all students to be po sitively related to motivating women (and other minorities) in mathematics, upon reading the literature a strong case is made for additional support to different groups. Although I will focus the majority of the paper on college experiences that influence women in SME majors, literature also points to the influence of pre-college coursework. â€Å"Maple and Stage (1991) found that students who took more science and math courses in high school were significantly more likely to choose science and math majors in college† (Trusty, 2002). Farmer, Wardrop, Anderson, and Risinger (1995) found taking elective science courses in high school had a moderate direct effect on persistence for women in science-related careers, but taking elective math courses did not. (p. 163) Although in this research taking elective math courses was not found to effect persistence of women in science-related careers, I contend that math courses are still critical as they are prerequisites for science electives of chemistry and physics. The National Science Foundation has reported, â€Å"young women have lower interest in math courses and take fewer advanced math courses† (Farmer, Wardrop, Anderson and Risinger, 1995, p. 157). In addition, Seymour and Hewitt (1997) found the effects of inadequate high school preparation to be the most common contributor to early decisions to switch from SME (science, mathematics, engineering) majors to non-SME majors (p. 79). Seymour (1995) also points out that studies have noted â€Å"the subtle deterrents to active participation in mathematics and science which bear upon precollege girls† (p.

Economics Unit †housing prices from different cities Essay

The cost of housing is commonly the reflection of the value of the land plus the price of the house and the amenities that come with it. This is often affected by what’s around the place, the nearest recreation areas or sceneries. This affects how housing is priced, and is also usually affected by the supply and demand of the land. Because of this, there are various considerations when choosing where to have a house, including the total costs and what you’ll actually get from it. Usually, these prices also vary from city to city, as it is known that not all cities are the same regarding what you get from the housing deals, like the nearest public transportation, market, and schools. These all appeals to the needs of the people, and these are usually the ones that affect the pricing. The housing prices are directly affected by the changes in supply and demand of the land. This is because of the developments done in housing, wherein house prices are thoroughly based on the value of the amenities that are directly available in the neighborhood (Nelson). Because of this increase in demand, there will be an increase in the competition for the houses, since there are a lot of people wanting the same thing, and that is a good housing. As a number of residents are acquiring homes, the more the managers of the land would try and make sure to provide benefits for these residents. This includes additional security, recreation areas and shopping areas for the people. They are not only investing on the housing that they are being sold, but also with the things that come with it that would surely benefit the people. This is how the housing value is affected when there is an increase in demand: it is not only because you have to increase the price when a lot of people demand for housing in a specific city or area, it is also because of the increase in the services that one should provide for these increasing number of residents. The cost of those additional amenities would then be reflected in the housing price: the more amenities offered, the higher the price (Duca). Comparison of different cities In order to actually see how amenities affect the price of housing, the housing situations in various cities are compared. This is by comparing the price of a 3-bedroom, 2-bath house in several cities like San Francisco, California; Topeka, Kansas; Dallas, Texas; Concord, Massachusetts; and Seattle, Washington. The results for the housing prices in these different cities were varying, and it is because of the added amenities that you can find available upon purchase, plus the neighborhood and the type of house. The most obvious result was between the housing of a 3-bedroom, 2-bath house in San Francisco, California and Dallas, Texas. The cost of housing in San Francisco, California ranges from $600,000 to a million US dollars. Meanwhile, the cost of housing in Dallas, Texas for a 3-bedroom, 2-bath house ranges from $40,000 to a hundred thousand US dollars (Realtor. com). The difference is quite large, and this is roughly because of the amenities that are included upon purchasing these houses. Housing in Dallas, Texas doesn’t offer much, wherein it is far from public transportation, and are often in subdivision areas. On the other hand, housing in San Francisco, California has amenities like community exercise and recreation areas, hill/mountain view, Water view, and so much more. Because of those differences, the prices of these housing deals are comparatively far from each other. These differences in housing deals give the people choices, wherein they are free to choose what type of amenities they want in their house. Also this variety would give them a wide array of choices, either wanting a plain, not so costly house, or to a fully-packed house that would surely cost them money. Other amenities present (or lacking) in some of the houses in various cities which could have affected their prices includes access to shopping areas/markets, nearby elementary or high schools, parks and recreation areas, and the type and quality of the house itself. With all these, the price the housing offered in the various cities is greatly varying. References: Duca, J. V. (2005, September/October 2005). Making Sense of Elevated Housing Prices.

Great Chicago Fire Essay - 1788 Words

Great Chicago Fire I have no passion or desire to write about a thunderous destruction of a city or the death of hundreds of people. Yes, I have no connection to this topic, besides my home being 30 minutes from downtown Chicago, but that does not mean that this fire does not pertain to me or anyone who lives in a completely different state for that matter. So, just because I have never experienced a disaster of this magnitude does not mean that my lips should stay shut regarding the topic of the Great Chicago Fire. What must be done is to look at events and, for that matter, life in a certain perspective that is not always one-sided. This one-sidedness can come from focusing on a particular outcome without realizing what else†¦show more content†¦From there, a piece of debris was flown onto an oil tanker located across the river in the North Side. The North Side was ablaze. It was a terrible night for many of the residents of the city of Chicago and is one that will go down in infa my until the end of time. The final totals for the fire were at the minimum 300 deaths, 70,000 buildings burned to the ground, 100 thousand people forced to homelessness, 73 miles of street were incinerated, and 200 million dollars in damage. There are many examples of struggle and despair during the fire, but there is one that I found very compelling. This excerpt from a letter written by a businessman from Chicago in 1871 brought into account the amount of people who came back and tried to save their precious belongings instead of focusing on getting out of town. The man in this example was able to sneak away with his life but faced some very close to death moments. â€Å"†¦I therefore started on my return, but, besides having to walk over ground almost too heated to walk on, and through burning piles of merchandise, I presently encountered such a shower of cinders, dense smoke, and driven sand (every grain of which seemed to me impelled with a force sufficient to make it sink in the skin) that from sheer disagreeability, if notShow MoreRelatedThe Great Chicago Fire983 Words   |  4 PagesOn Sunday, October 18, 1871 the largest fire Chicago has ever seen broke out.
