nutrient deficiences on fescue essays In our experiment, different combinations and rates of Nitrogen, Potassium, and Phosphorus were applied to Festuca arundinaceae, or tall fescue. The goal was to determine which rate and combination would result in the highest rate of shoot growth. Tall fescue is a cool season perennial. It is used in areas with cold winters and mild to hot summers. General uses of tall fescue include as pastureland in some of the southern states and also as lawns, athletic fields and roadsides in certain areas. It is a coarse bunch-type grass that can have rhizomes that spread slowly. Tall fescue can handle soils that are wet, but also has good drought tolerance. Some of this drought tolerance can be attributed to the relatively deep root system it has. Besides drought tolerance, tall fescue tends to have a relatively good tolerance for heat and medium cold tolerance. Shade is tolerated by tall fescue as well. The ideal pH for tall fescue is from 5.5 to 6.5, but will survive under pHs that range from 4.7-8.5 (Beard, 1982-p594). Tall fescue has a medium cultural intensity. Mowing height of two to three inches is relatively high compared to most turf grasses (Collins, 1999-p 76). The high mowing height allows for more photosynthetic area than other commonly used turf-grasses. Nitrogen is a mobile macronutrient that is mostly available in pHs of 6 to 8 (Dole, 1999-p 68). Beyond the given range, it can be difficult or impossible for the plant to receive and utilize the nitrogen. Water is also necessary in order for nitrogen to be used by the plant. Nitrogen functions in leaf greenness, ability of the plant to recover from stress, quantity of grass clippings, root and shoot growth, resistance to disease, and cold, heat, and drought tolerance. The result of a nitrogen application is a sudden spurt of growth that depletes available nitrogen in two to six weeks. To keep growth at a steady rate, light and frequent fertilizer applications s...

HANA

HANA The movie â€Å"HANA-BI† or â€Å"Fireworks† tells a story of a retired police officer who has left his work for emotional reasons, due to the accident with his friend. As such, his life has turned into a completely different experience, and he has to adjust to different values and morals.Advertising We will write a custom article sample on â€Å"HANA-BI† a Movie by Takeshi Kitano specifically for you for only $16.05 $11/page Learn More One of the key scenes in the movie is where Nishi is sitting by the fire with his wife Miyuki. She has leukemia and Nishi is taking care of her. The inevitability of the decease is written on his face in several instances during the movie. The scene where they sit and laugh by the fire is significant for several things. The formal elements of the clip include a married couple spending time together. From a side, it would be impossible to suppose that one has a deadly disease while the other is eternally s addened by the fact that nothing can be done. It seems like a separate moment in time where all the worries are taken away, and only the fire and the company of a close person are being paid attention to (HANA-BI). The thematic elements of the clip are tied into the main theme that even though there are happy moments, they must be mixed with pain and suffering. It is thus representative of life and all the perturbations that make people so vulnerable to the circumstances and conditions of being alive. The scene is thus connected to the whole film, as one story flows into another and the setting is changed completely (Phillips 2007). The continuous nature of life is represented by the situations that Nishi finds himself in, and the course of action he chooses. The scene is filled with feeling because Kitano has had a life full of emotional situations, and has experienced pain first hand. He knows how important it is to value each moment that is given to people, as even those miniscul e pieces in time can be taken away in a blink of an eye (Norden 1994). In a greater historical context, it is possible to recognize the hardships that accompany the battle for happiness and survival. A particular emphasis is made on the struggles of a person who is fighting an illness, their personal lives and those of people around. It is meant to show the pain that relatives and close people go through. Previously, such deadly conditions were even less managed than today, so it is meant to signify the progress that has been made, even though it is not enough to save people’s lives.Advertising Looking for article on art and design?

This shows a true emotional connection that he has with anoth er person, and this scene is meant to teach others how fragile life is (Belton 1996). The movie is filled with moments that are emotional, sentimental and heartfelt. It has been acclaimed as a work of art because it touches the inner corners of the person’s heart, and makes one wonder about the true values of life. The scene very directly and vividly describes the relationship between two people, and the connection to the outside influences which are rarely anticipated by people and their seeming strength.

Cognitive Development Theory - Essay Example Cognitive development is related to socialization. A child's ability to judge social relations and gain sense of morality are largely dictated by his intellectual readiness and interaction with his environment (Levitt, n. d.)Cognitive development theory focuses on the following concerns: the specificity or generalizability of domains in cognitive ability changes; the occurrence and rate of change or the existence of qualitative different stages; the processes occurring in physical or psychological aspect of an individual; and the factors affecting development.Cognitive development theory makes sense of one's environment and physiological conditions at which an individual interacts and functions to provide a system by which the process of learning and teaching might understood and controlled for maximum and optimum cognitive development.On the nature and development of intelligence, cognitive theorists particularly Jean Piaget and Lev S. Vygotsky both consider "the role of environment al factors in shaping the intelligence of children, especially on a child's ability to learn by having certain behaviors rewarded and others discouraged" (Encyclopedia of Childhood and Adolescence). Piaget believed that development proceeds from the individual to the social world.Piaget believes that child's knowledge is composed of schemas, or knowledge units, which serve as basis for organizing past and new experiences. These schemas are continuously defined and redefined through "assimilation" and "accommodation". According to Piaget, learning and understanding concepts can only happen when new things are incorporated into old and previously learned concepts. Otherwise, the schema will change to accommodate new knowledge. According to Piaget, cognitive development is a result of learning. Development occurs due to continuous incorporation of things from previous personal experiences. Learning is individually oriented. Development precedes learning. Piaget believed that intelligen ce arises progressively in the baby's repetitive activities. Vygotsky, in contrast believed that instruction is necessary to attain development. Vygotsky believed that development begins at the social level and moves towards individual internalization. Social and cultural factors are important in the development of intelligence. Through "scaffolding", an adult guided activity, a child learns new things gradually until he reaches new level of understanding. Unlike Piaget, Vygotsky believed that learning precedes development. Vygotsky might have been aware of instances when a child has understood a concept before they can demonstrate their understanding of it. This happens when a child's motor skills are not yet advanced enough or their language skills are not sophisticated enough to indicate their knowledge and mental processes, hence adult guided instruction is recommended to attain development (http://social.jrank.org/pages/145/Cognitive-Development.html). Both theorists however ag ree that development may be triggered by cognitive conflict. Any change in learning skills and knowledge can only happen if the learner has realized the difference and inconsistency with his existing understanding. Like Piaget, Vygotsky believed that children's egocentric speech was an important part of their cognitive development. They differed in their views of the purpose of egocentric speech. Piaget considered egocentric speech suggests that the child is self-centered and unable to consider the point-of-view of others. Vygotsky seen it as a
