...1353-1360 (2010) The potential of seaweed liquid fertilizer on the growth and antioxidant enhancement of Helianthus annuus L. N. AKILA and T. 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...

...Analyzing Poem At first the only aspect that really stood out to me in the poem, I Shall Paint My Nails Red, was the acts of a woman talking about feminine things that woman like to do to change up their appearance. After thoroughly analyzing this poem I came to the realization that it was much deeper than that. Every line of this poem is a distinct statement filled with self-expression and confidence. I Shall Paint My Nails Red by Carole Satyamurti, takes the simple act of painting your nails and shows the meaning behind it. This poem hits home to me because painting my nails is something I enjoy doing with my grandmother. My grandmother has never gone a day without having her nails painted, and after reading this poem I understand why. To me, womanism is the main theme that Satyamurti is trying to portray in this poem and it is being shown through beauty, strength, and passion. Beauty can represent a numerous amount of things, and in this poem Satyamurti does a remarkable job at capturing the true meaning of beauty. “Because I am proud of my hands” (Satyamurti 2), after I broke this poem down piece by piece, the imagery in this line caught my eye. I relate the pride she takes in her hands after painting them to my grandmother and how I never see her go a day without having her nails painted. Although painting your nails is a simple thing, it makes you feel good about yourself. My grandmother walks with confidence every day and though it may not be just because of her nails...

...Carole Satymurti’s “I Shall Paint my Nails Red” is a wonderful poem which I found myself closely relating to. I feel that in this poem she reflects many sides of a woman’s life. It may be understood to have two separate messages, the direct and the hidden message. Satymurti does this through showing both the complexity of a woman’s life, and the simplicity that also exists within. At first glance, “I Shall Paint My Nails Red” gives a more obvious and direct amusing message in which she states different reasons why she would paint her nails red. Each line puts the reader in a different situation which may even be applied to our own daily lives. Satymurti does this by using every day examples and using them to suggest often absurd reasons for her to paint her nails red, adding a bit of comedy throughout the poem. Underlying each idea, however, Satymurti implies a deeper message about women and the many roles that they play in society, and the way that they view themselves. The first idea Satymurti suggests in the poem is, “Because a bit of colour is public service”. Here, she is implying that in painting her nails red she is in fact doing others a favor. This line makes me think of a woman loading her groceries onto the cash register before paying, showing off her bright red nails and provoking a smile on the cashiers face. She seems to believe that anywhere she were to go with these red nails, the world would see them and appreciate them. Underlying this main idea however...

...The problem of this case is that, as in the financial report for the most fiscal recent year, the overall profitability of Classic Pen company goes down despite of the introducing of its new two products, RED and PURPLE pens, which show more profitable than the traditional BLUE and BLACK product. These two new products are expected to be sold at premium selling prices about 3% and 10% respectively in the order and the new line, particularly PURPLE, in fact, showed much higher margin over the others. The problem was addressed is that the production technology required for the RED and the PURPLE pens demand specifications. Especially, making the RED color needs more changeovers, which leads to waste lots of time on purchasing and scheduling and management activities as well as money. In order to come up with a management decision under this situation, the controller is considering of using the activity-based costing (ACB) system to create the financial statement instead of using the traditional, job order costing system. Unlike the job order costing which maintains records and allocate cost on top of direct labor, ABC focuses on activities. Therefore, it leads more cost pools to be used to assign overhead costs to products. Four cost drivers which directly related to activity cost pools to assign overhead costs could be used for this case. As a result, costs are assigned more directly on the basis of the cost drivers used to produce each product. II. Strengths, Weaknesses,...

...Cp8, Coordination Compound, Synthesis & Product Yield Observation, Description & Questions 1. Compound 1 was initially a light blue color. After adding the oxalic acid and heating it changed to a yellow color. Once the saturated potassium oxalate solution was added it changed to a red color. Once most of the hydrogen peroxide was added it changed colors again to murky brown. Finally it changed to a green color after the solution was brought to a boil and more oxalic acid was added. Compound 3 were crystals that of the same green color. 2. We started with: 10.000 g Fe(NH4)2(SO4)2 • 6 H2O / 392.14 g/mol = .02550 mol. We ended with 6.557 g K3Fe(C2O4)3 • 3 H2O / 491.24 g/mol = .01335 mol. .01335 mol / .02550 mol * 100% = 52.35% yield. 3. If the yield had been greater than 100% percent the likely reason would be that some liquid from the washing process hadn’t been allowed enough time to dry and caused the final weight measurement to be off. 4. Since the yield of the final solid crystals was about half of the starting amount it is likely because the solution didn’t have enough time to completely form into the solid compound. Also, in there may have been a limiting reagent that wasn’t taken into consideration. 5. Charge on iron in reagent I (Fe(NH4)2(SO4)2 • 6 H2O) = 2+ 6. Charge on iron in product III (K3Fe(C2O4)3 • 3 H2O) = 3+ 7. K3Fe(C2O4)3 • 3 H2O = potassium trioxalatoferrate(III)...

...normally a movie is shot in full color, Sin City is shot in black and white, and then color is later added. The use of color in Sin City is used to differentiate characters, foreshadow events, and to set the mood for scenes to come. Out of all the colors used in the film, the most common is red. It is used to show a variety of things from violence to blood, to differentiating the heroes from the villains. Furthermore, one of the most interesting uses of red, and probably one with the deepest meaning, is seen in the scene between Marv and Lucille when they are trapped inside Kevin’s bunker. Marv’s face is completely scathed, due to the fight he has with Kevin, and the only color the audience sees is the red blood on his face. During the scene Marv approaches Lucile and gives her his jacket, and that is when the audience first see’s the blood on his face. The only color is red. It has a variety of meanings in the film, such as violence and murder, but in this scene it means something else. Red shows the courage and the warrior inside Marv. He’s doing whatever he can to get them out and eventually does. Throughout Marv’s story the marks never go away and his blood is always shown by red. The significance of it is to show that although Marv is a...

...The Shades of Red By Angela Yohey We were children pushed together by marriage. We became sisters by choice much later in life as adults. Colleen Michelle was born August 28, 1971 in the Bloomsburg hospital just nine months after me to a woman not yet my mother. Her birth was just like her, in a hurry to start living life. She decided to leap into the world a whole 19 days early; no one, not even a doctor was going to tell her she needed to wait one more second to do what she was ready to do. She has continued to live her life with enthusiasm and energy. She was raised as an only child in a family that now has three daughters. I was raised with my biological sister Stephanie by our mother in Bloomsburg, Pennsylvania. Our parents divorced when I was five and Stef was eight. Colleen was four when her parents divorced. Her mother and my father married, and soon after they moved to Pittsburgh where Colleen would be raised. I always thought she had the best of him, and for that I was envious. I did not know their relationship had struggles from so far away. It would take years before a child would become a daughter and a stranger would become a father. Her very nature is flamboyant, as are the many shades of red in her personality. When she enters a room, the door flings open with a flurry of activity and chatter. It is straight to kisses and hugs that are not your average embrace. She takes you into the fullness of her...

Looking at the new product costs per unit (using ABC) the cost per unit for each product is much different then found under traditional. The cost per unit found under the ABC method was different than what the unit price for each product was being sold for. For blue and black pens the company was making a profit on each pen there were selling (comparing $1.18 product cost for blue and $1.16 for black which were each being sold for 1.50). Red pens cost $2.23 each to make and were being sold for 1.55 each which resulted in a loss. Purple pens were losing the company even more money with costing 4.95 to produce but were only being sold for 1.65 per pen. Under further calculations using the ABC method it was found that blue was the most profitable followed by Black, but that Red and purple were causing the company to lose money, Red was losing the most in dollars with around $6000 while purple was losing a little over $3300. The profit margin was also different than what the traditional product costing found. ABC revealed that Blue and Black pens were actually more profitable than what the company originally...

...Gogh has depicted himself in Self Portrait with Bandaged Ear. In Self Portrait, Affandi has characterised himself as a semi-abstracted figure against a plain background, with the highly detailed face in stark contrast with his torso, which as suggested by its dark green contour only (without any colouring within), appears to only be vaguely apparent. Affandi also seems to be placing extreme focus on the human emotions or mood, presumably meant to be conveyed by the extremely detailed expression on the face that he has painted. In fact,everything is lumped together (in fact, most of the colours used) on the face in his painting. Upon closer examination, one would find that Affandi’s face as depicted in this work is actually more of a mass of red rather than anything else, and lined with blobs of different colours (namely yellow and green) presumably to represent the hair. Details on the face are not clearly made out, rather only a faint outline of the eyebrows, eyes and nose is apparent. This is as opposed to Self Portrait with Bandaged Ear in which van Gogh has similarly depicted himself, albeit in a far more realistic manner, where all his facial features are clearly visible and modelled. Close attention is also paid to his body, clothing (as evidenced by the precise and exacting brushstrokes that make up his coat), and background as well. Unlike the unevenly distributed blobs of paint that are characteristic in Affandi’s Self Portrait, van Gogh’s usage of the...

The story is from 2006. It consists four people: Sam, who is the main character, her father, her uncle, Harry, and his client, Layton. The story takes place at a river, where these four people are on a float trip down the river. Through the trip Layton is getting more and more interested in Sam. Sam is not sure about her being interested, but as time goes, she let him seduce her. They go for walk and Layton teaches Sam how to shoot with a gun. And at the same evening things get a bit heated up, as Sam gives him massage. But nothing serious happens. The main theme in this short story is “growing up” and “being a teenager”. Sam is about to go from being a child to being a grown up adult and this transition brings a lot of confusing to Sam. When you are a teenager you suddenly get an identity crisis, because you are lost in the middle of being a child and adult. This is seen when we hear about Sam’s feelings about her soon being a sophomore “In the fall, she would soon be a sophomore, which sounded very old to her.” (P.8 L. 4-5). Besides the identity crises, you will face a frustration over your sexuality. You suddenly realize that someone is interested in you as a woman – or...

...Within Beloved, colour is a recurring and significant theme, particularly the colour red. Perhaps this is because red can symbolise such a variety of things and throughout Beloved, the meaning of these objects varies. Beloved is full of strong feelings and emotions so the use of colour could represent these feelings. The colour of skin was a sensitive issue so the use of colour within the novel could represent the treatment that the characters would have had to deal with. It would seem that overall, red symbolises life and the intuitive nature of human existence however in Beloved, life often goes with death and therefore red symbolises presence and absence. For example, the roses lining the way to the carnival, were already 'doomed' and 'dying'. This is significant as this outing could be the start of a new and better 'life' for Sethe, Denver and Paul D but these 'rotten roses' simply have a scent of 'death' and thus, perhaps not a new life for 'the three shadows'. In a way, red could symbolise hope, but hope that leads to nothing but more death and misery. The red rooster signifies manhood to Paul D, but a manhood that he has been denied of. Denver's red velvet as another example is an image of a brighter future but it is unlikely that her future will be much better. For a reader, this use of colour, particularly with the idea of lost hope, is effective and can be quite moving. Right from the beginning of the novel, colour is used to set the scene and show the mood...

...meeting. Intrigued by this fact along with the role color plays in the world of women’s fashion in addition to noticing women wearing red often than any other color during important personal or public occasions; the aim of this dissertation is to examine the color of clothing worn by women in different occasions in order to explore whether colors with specific reference to red really play an important role in women’s fashion along with to address the question of whether women dress up in red as they perceive red to be a symbol of sexual attraction for men or it is a mere coincidence to see women dress often in red. Starting with an overview with theories related to color psychology and male gaze, the earlier conducted experiments on the color red and women and a self- conducted survey will be analyzed to see if the elements of the theories are in fact evident in the color chosen by women. Colors which both support and go against the theories will be further analyzed before this dissertation lead to its final overall conclusion. LITERATURE REVIEW This literature review will critically examine the theories and the earlier studies that have already been conducted in this area and draw on any conclusion presented in the studies to back up the findings of this dissertation. Much of the research in this area has looked into studies where red is considered to increase the physical and sexual attractiveness of the women which results the men to view women as more...

...self worth, desires, and his destiny. In this complex emotional state, he visualizes words and feelings as color: the gleaming gold of his pride, the dark green depths of despair, and the red fires of lust. He would visualize these colors because of his longing desire to make sense of it all. He has realized that from the sin of lust, all other sins have emerged. Stephen is proud of his status and uses it to justify his sins. His success in school inflates his ego. He lords over people with pomposity and has a golden exterior, but under that thin shell is his sin and insecurity. His golden shell is a façade for his shame and the more he feeds his sin, the more he feels the need to devote himself to religion, as if the two will cancel each other out. Green is the color of the rotten stink that is the dark side of his soul. His mind is split. One side of him is a devout catholic who is excitedly persuing god, but while he is venerating Mary, he is daydreaming about prostitutes and the desires of his flesh. All this is swirling around in a cold swamp of lucid indifference where strange things hide under the dark surface. Stephen is lazy and sloth like, a condition of his mental frustration at the world of temptation. The only light that is provided to his fetid green soul is from the glowing red embers of his lust. Steven’s lust is at the heart of his problems. Perhaps the most destructive and addictive of the sins, it burns unchecked like a wildfire in his life. The warm blaze...

Emotions in octopus: The octopus changes their skin color, pattern and texture because of certain specialized skin cells. This change matches their mood. It also changes to communicate with or warn octopuses. Also, it does this to hide from predators. In captivity, Pacific octopuses even show both personalities and emotion. Some octopuses are shy, others are bold. Some are aggressive and others are fearful. When hungry, they have been found to invert their bodies, pointing their suckers upward, in a bowl shape-like a person’s begging hands. If the octopus does not receive food, he or she will swim back while turning a bright red color. This is believed to be an invertebrate’s display of the anger emotion Octopus can eject a thick, blackish ink which means it is being attacked and it is scared.
