JEYADOSS* Department of Chemistry and Biosciences, Srinivasa Ramanujan Centre, SASTRA University, Kumbakonam - 612 001 (India). (Received: September 03, 2010; Accepted: October 11, 2010) ABSTRACT A field experiment was carried out during the chithiraipattam (April-May) in India in 2010 to study the effects of foliar applications of different concentrations of seaweed liquid fertilizer (SLF) of Sargassum wightii on growth, biochemical constituents and antioxidant enzymes of Helianthus annuus L. to explore the possibilities of reducing or avoiding chemical fertilizers and to obtain the highest growth and productive parameters. The foliar spray was given twice in 15days interval at two concentrations (2.5%, 5.0%) of SLF. The aqueous extract of Sargassum wightii was found to promote almost all the parameters such as shoot length, root length, leaf length, leaf breadth, fresh weight, dry weight and number of leaves. The biochemical contents such as chlorophyll a, b, total chlorophyll, carotenoids, carbohydrate, total phenols and antioxidant enzymes such as catalase, peroxidase and glutathione peroxidase (GPX) were also found to be higher in the leaves. Among the two concentrations 2.5% was found to produce better results in almost all the parameters. The results revealed that foliar application of seaweed extract could be a promising option...

...The Color Red In Director Sam Mendes’ American Beauty, Cinematographer Conrad Hall utilizes great lengths of visual silence to signify the enveloping, jarring presence of Lester Burnham’s own, imaginary world. Conrad Hall also creates startling visual silence when intensely focusing upon each character of American Beauty, and consistently morphs the lack of apparent objects into an inconspicuous focus on the striking color of Red. Through this enigmatic color, Conrad incessantly portrays the goal and lifelong desire of every character in the movie, starting with Lester Burnham. Each character is faced with a dream that is not recognized starting from the opening scene, but becomes gradually apparent through the blatant indication of Conrad’s color choice on various objects in each subsequent plot point. There are numerous shades of red as well; contrasting between each character’s superficial appearance, such as Jane’s distinct albeit crude lipstick, and the essential, authentic item of desire, such as Angela Haye’s falling rose petals in Lester’s fantasies. With the brilliant amalgamation of red and specified isolation of Lester, Jane, Carolyn and Ricky, along with the enveloping shades of gray in between, Conrad imparts a language of film unique to his own perspective: telling a story not through the conversations of character, but through the stark contrasts of color and use of varied visual silence. Lester Burnham first sights the color red through the lovely, soft rose...

...that majority of the time colour is seen by the viewer before the actual image. This information allowed me to think in a more critical way and also made me think about how I can use significant colours to evoke a certain response. Red Red is one of my favourite colours as I feel l gain the most emotional impact from. I find it interesting how I am affected in a physical way for example when I feel warmer wrapped up in a red blanket rather than another colour. The possible double meaning and strength is also appealing to me. Being the lowest wavelength, red is a powerful colour. It has the property of appearing to be nearer to be closer than it actually is therefore grabbing your attention. For this reason, it is the most used colour for traffic lights and signs around the world. It’s affects are actually physical and it has been proven in research to raise the pulse rate in people, giving the impression that time is passing quicker. It can activate the basic instinct of flight or fight in the body stimulating adrenalin. Red has also been associated with anger which can cause irritability in some people. Purple This is another one of my favourite colours as it represents my spiritual side. I like how it combines aspects of red – dynamic and active – as well as blue – cooling and calming – coming...

...that I detected was freedom. He talked about how water was so unpredictable and free and in one of his pieces; he connected dozens of green leaves and formed a line with them. He then put those leaves in a river. The leaves’ movement was not predictable and showed freedom. Goldworthy also depicted peacefulness in one of his pieces. Andy woke up early one morning before sunrise and worked on an ice sculpture. Ice is peaceful to me because it his frozen and never moving, depicting stillness and peace. The sculpture was finished just as the sun rose and gleamed perfectly on the piece, which depicted peace in my eyes. Andy Goldworthy was also passionate about the color red. Red in my eyes shows aggression, anger, and power. In one of his pieces, he would grab different rocks from riverbeds that would produce a deep red color. He would then put that color in several places around the river, which in my eyes depicted aggression. Goldworthy is very passionate about the emotion that he puts in his work and it was clear from the...

...concentration levels of the Cobalt(II)Chloride decreased along each test tube, you could tell since each test tube became a lighter shade of reddish pink. The reason to this was because I needed to determine the wavelength and absorption of the colored solution in each solution. The absorption spectrum(absorption spectra) is used to measure the absorption of radiation as a frequency or wavelength due to the interaction of the substance with the sample. It is used as tool to determine the presence of a particular substance and the quantity of the substance present in the sample or samples, as in this case I have 5 test tubes. The absorption spectrum for cobalt(II)chloride with the color red has a wavelength of 680nm(nanometers). This means that the solution did not absorb a lot of the color red. From the graph we can see that green was absorbed the most which had a maximum wavelength of 551nm(nanometers). Since the green was mostly absorbed, it was not reflected through the sample when hit with light. The absorbance of the cobalt(II)chloride is found first because with that we are able to find out the concentration level by using the formula M1V1=M2V2. For each test tube the concentration levels were different since they each had varying dilutions. After finding the concentration for all 5 test tubes we used logger pro on the computer to create a beer’s law graph. Logger pro then...

...Philip Evergood in 1934. These people are unevenly spaced apart throughout the painting, either by themselves or paired with another person. The enclosed area has bleachers surrounding the spider web-like floor that is separated by handrails. On the top left hand side of the painting there is a man who is lounging across a few rows of the bleachers. To the left of this man you see a skeleton hand that is holding a $1,000 that appears to be hanging from the ceiling with the light fixtures. In that same area on the wall there is the word “walkathon” and “first aid station” with a red cross over a doors way. To the left o the door way you see a lady that is in all white from head to toe. To the right of the doorway, there are men sitting and one man standing at a table and they are placed under a red sign that has white lettering that says “Winner takes all Couples $1000 Solo $500”. Right next to the red sign there is another sign that says “49th day” placed above a Mickey Mouse clock. The bleachers on the right hand side of the painting there is a man in a black suit sitting next to a lady in a pink dress. Below the couple, sitting on the bottom row of the bleachers is another man in a suit and a hat hanging over the handle bar. On the bottom left corner of the painting there is an arm of a woman that is wearing a spiked gold bracelet and in the right bottom corner there is the lower part of a man’s face who is smoking a cigar. The way the man, who is smoking a cigar, hands are...

...Adver-ties Things In to Everything When people flip through magazines, advertisements are on every other page, but they are quickly overlooked. Advertisements are part of people’s daily lives. This is a big part of what advertisement makers take into account. They need to use certain methods to somehow catch people’s attention in the piles of advertisements that surround everyone. Advertisements are actually mini works of art that take many man hours to manufacture. Advertisements are selling products by use of manipulation on media. There are many parts to advertisements that consumers are blissfully unaware of but affect them psychologically. Many things drive humans to buy goods thinking it will attract a mate, or they think it will fill a need. Advertisement makers are very good at going into a person’s mind and making them think the products they are selling are needed. The makers of advertisements are skillfully weaving masterpieces that a reader will glance upon, but still get a message conveyed to them via imagery, manipulation, and text. The audience of this advertisement might be that of the fashion conscientious. This specific advertisement was found in a 2010 Cosmopolitan magazine. This particular magazine is targeted towards women ranging from the age of 20-40 years of age meaning advertisements in the magazine are also geared towards women in that age group. Specifically this advertisement is most effective when viewed by women who are conscious of what...

...see. The writer of the ad used a man in his picture. I think that he used a man in the picture not to be subjective to just men but used the man as in the context of man kind. Man kind meaning man and woman. This is a gas credit card advertisement and you know that by the picture of the credit card with the gas symbol. You know that it is a credit card because at that bottom of the card is a place for a name. This ad is intended to reach consumers who travel a lot. The advertisement colors appeal to both men and women. The use of bright colors appeals to women for example the use red and yellow. The colors black and blue appeal more to men. The advertisement uses the color yellow to transition to the many examples that are presented in the article to inspire people to want the credit card. The tire rim is used as an example to get to the picture of the red car. You know that it is a red car because it has a picture of a white plate on it which then transitions to the money and then in the middle the gas credit card. All of these pictures are used as examples for people who travel a lot to try to get them to want the card as a way of saving money. The ad is saying click here to save money. The ad is not intended for just one type of person it is intended for all types of...

...never opened since they were born? Those are some of many questions that we may possibly ask a blind person. Can we explain them what color red is? We’ve all seen what it is like. To explain it we have to “turn on a different mode” in our heads. We do not only see colors. Like this red dress, black cat, hazel eyes. When we close eyes and think about color red we see so much more. So we can explain color by comparing it to some thinks that blind person may know about. One thing that we can see are emotions. Actually they are usually both very intense, but extremely different: love and hate. We can describe color red as love, passion, infatuation, desire. When seeing lovers we may thing of red sort of halo moving with them. We can also see this kind of halo but maybe in darker shade around people in fight. When blind person will think of hate, anger, cruelty, ferocity. We can explain to this person that color red is like these emotions, very intense, after some time it may begin to bother us. Color may also be explained to blind people as things that are typically red and they know how those things are like. A flame, burning wood, coal in the BBQ, are all red so it can be explained as something hot, burning. Another red thing is blood; we all have it in our system so fluid that runs through our veins can be one of explanations Color red is also visible on traffic lights and on the stop sight. It can be seen as a sign to finish doing something or as the end. Being blind does...

...Blue is the colour between violet and green on the optical spectrum of visible light. Human eyes perceive blue when observing light with a wavelength between 450 and 495 nanometres. Blues with a higher frequency and thus a shorter wavelength gradually look more violet, while those with a lower frequency and a longer wavelength gradually appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres. In painting and traditional colour theory, blue is one of the three primary colours of pigments, along with red and yellow, which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet, blue and yellow together form green. Blue is also a primary colour in the RGB colour model, used to create all the colours on the screen of a television or computer monitor. The modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao.[2] The clear sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. When sunlight passes through the atmosphere, the blue wavelengths are scattered more widely by the oxygen and nitrogen molecules, and more blue comes to our eyes. Rayleigh scattering also explains blue eyes; there is no blue pigment in blue eyes. Distant objects appear more blue because of another optical effect called atmospheric perspective. Blue has been used for art, decoration and as a clothing dye since ancient...

...Chem 001: Problem Solving Investigation in Analytical Chemistry PROBLEM Are red flowers really red? Two students were having an argument about pigments in red flower. One said that red petals can only contain the red color, whereas the other students thought that the red color could actually be a mixture of color. Plan an experiment to investigate if the pigment in red flowers consists of one or more colors. In your investigation think about how you can extract the pigment and check whether it consists of one or more color. PLAN FOR INVESTIGATION A. Purpose of the Investigation The purpose of this investigation is to know whether the pigment in red flowers consist one or more colors. The goal of this experiment is to analyze the pigments found in flowers using paper chromatography. B. Materials/ Apparatus The materials used in this experiment include filter paper, scissors, pencil, ruler, clean jar or drinking glass, large- mouth glass jar, water (at least 60 mL, distilled water is preferable, but tap water is also suitable), 70% isopropyl alcohol, measuring cup, piece of scratch paper, coin, timer or clock, and of course red flower petals. You will need at least 2 flower petals from at least 3 different plants. Tip: Larger petals work better than smaller petals. C. Steps/ Procedure Cut the chromatography filter paper into strips that are about 2 cm wide and as long as the large-mouth glass is tall (the strips should all be the same size). You will...

...Making a pen bag I have a very cute pen bag which you can put your pens and eraser. If you look at it in the front, the shape is a rectangle. If you look at its profile, it is a triangle. The design is for the capacity. There is a red plastic zipper on the top. Red is a main color of the pen bag. It is two double, and the materials are different. The outside is the soft plastic, and the inside is the hard cotton. If it is dirty, you can clean it with water, or wipe it with wet rag. If you have time, you can try to make a pen bag. It is very easy, and making one does not need much time. Firstly, you need to find some materials. You can use the old curtain, or bed sheet. If you want to make a new one, you can buy the fabric in the Wal-Mart. If you want a simple style, you can choose a pure color fabric. If you want a Korean style, you can choose a calico. Another thing you need is fusible interlining. You can buy the zipper when you buy the fabric. They should be in the same place in the Wal-Mart. The quality of the zipper is very important because its importance reflect the quality of the pen bag. The color of the zipper has better be similar as the fabric, or same as the main color of the fabric. You need some strings which color is same as the zipper. Moreover, we start to make a pen bag. You cut two cloths as 22*18 cm, and cut the fusible interlining in the same way. Then you iron them separately, one cloth with one fusible interlining. The edges of the fabric...
