The Third Century Crisis - Research Paper Example The fact that the murder was carried out by this own people is a fact that made the citizens of the country lose trust in the running of the empire (Sisem, 2014). People had different views regarding the administration and this lack of trust made people not operate as a unit as they had been doing prior to the death of Emperor Alexander (Liu & Xiaobing, 2013). Many of the people that worked for the Emperor did not believe in him and they stated that the reason for this was that Alexander was weak and did not have the required Leadership styles (Wolf, 2005). Contrary to their beliefs, they had the idea that Alexander Severus was on the German side and was the reason why he resorted to diplomacy as a way of dealing with them. Another event that led to the collapse of the empire was the increase in the number of raids that took place in the years that followed the death of the empire. These raids came from different people in the administration and the reason for them was the fact that they all wanted to have a word in the running of the empire (Latourette, 2014). Many of the people had different ideologies regarding the best manner through which the citizens of the country could maintain their resources. These differences made the leaders implicate each other, leading to people turning on each other, and the result was the collapse of the Roman Empire. The outbreak of small pox was another cause of the collapse of the Roman Empire. Small pox was a common disease in those ages and the fact that physicians were yet to come up with a cure made the empire suffer a lot with regard to the number of people that died from it (Wong, 2009). Small pox was a disease that affected people across different ages and the consequent of this was a weak empire. Regardless of whether individuals had the disease or not it affected people both directly and indirectly (Gao, 2008).

Effects of Water Temperature on Plant Growth

Effects of Water Temperature on Plant Growth Abstract   Test the affect of microwave water and boiled water on plants. No major difference of the plants growth between boiled and microwave water, shown in the results. 1.0 Introduction The following experiment was conducted over a period of 5 weeks testing 2 different plant species on the affects of microwave water, behind the theory of microwave radiation altering the chemical composition of water. Based upon this theory the plants were experimented to see if microwave radiation alters the structure of DNA affecting the growth of plants. [Research Centre, 2006] Two hydrogen atoms and one oxygen atom is the very simple atomic structure of water. Causing it to have unique electrochemical properties. A slight positive charge on the hydrogen side of the molecule, with a negative charge on the other side. Water is a powerful solvent and is responsible for its string surface tension, as the molecular polarity causes water molecules to arrange themselves in patterns when a physical phase changes in water molecule. Specific heat is the energy amount required to change the temperature of a substance and wast has high specific heat. Large amount of heat energy, before it begins to get hot as its high specific heat. Helps organisms relate their body temperature as it releases energy slower and more effectively when caused to cool. Neither acid or basis with a neutral pH. The pH changes if substances are dissolved in it. Good heat conductor, conducting easily than any other liquid. Uniform vertical temperature profile for large bodies of water is due t he easy heat conduction. With a temperature range of 0 to 100 ° Celsius, allows the water molecule to exist in most places around the world. Being able to dissolve many different compounds and chemicals as its an universal solvent with a high surface tension. Adhesive, elastic and in aggregate drops is what water tends to be. Despite the downward of gravity the phenomenon causes water to stick to the sides of vertical structures. It also allows waves and water droplet formation and for plants to move water dissolving nutrients from their roots to their leaves. [Pidwirny, M. 2006.] A group of living organism with some 300, 000 different species characterised by their green colour, are plants. Trees, herbs, flowers and ferns are some common groups of plants. Sprout, seedling is the meaning of planta a Latin word in which plant originated form. [R, Conan-Davies. 2009] Each part of the plant plays a different role. Absorbing from the soil, water and minerals are the roots which act like straws. Extra food for the future is stored and helps anchor the plant, the tiny root hairs assist in the nutrients absorption. Acting like the plumbing system for the plant and supporting it, is the stem. In the form of glucose water and nutrients is conducted from the leaves to different parts of the plant. Being either herbaceous and bendable or woody. The small stalk which attaches the leaf to the plants stem is called the petiole. The leaves are where majority of the plants food is made, through the process of photosynthesis. The leaves are designed to capture sunlight for the photosynthesis process to work. The reproductive section of the plant is the flower. Pollen and ovules are contained in the flower, after the pollen fertilizes the ovule through pollination, fruit develops. Providing seed covering is the fruits role and is also edible to humans and animals. The seed is the basis of a plant. [Botanical Garden, 2009] Carbon fixation and photosynthesis conducted by plans and algae is the energy and organic material source in all habitats. The earths 20% composition is changed radically by the plants process. Internal energy which relies on oxygen to move and grow is aerobic organism such as animals. The nutrients of animal and humans rely heavily on plants. [R, Conan-Davies. 2009] Petunia is scientifically known as; Petunia x hybrida. [NC State University, 2010] popular low lying annuals provide a brilliant display and attractive colours and green foliage in garden beds or containers. Blooming all summer long. Growing best in full sunlight with soil the is peat based which contains vermiculite. Petunias will survive in the shade that at least 6 hours of full sunlight daily. With ranging colours from whites to yellows, petunias can be the main attraction in a garden bed with minimal maintenance. There are several varieties of petunias. Water the plants pior to planting them and allow for drainage. Fertilising with a liquid fertiliser or soluble on every two weeks will help keep plants healthy. [Garden Guides, 2010 information peg] Calendula officinalis is commonly known as the marigold. [Eco India, 2008] Easy to grow and provide bright large displays in the garden. With a strong unpleasant scent, its effective for repelling garden pests. Coming in yellow, orange colours, can be planted in pots or gardens. Being able to be grown anywhere in all but cold climates. To help conserve moisture in the plants mulch and fertilise to keep them healthy. Regular water and will bloom throughout the summer and autumn and will keep pests away. [Garden Guides, 2010 information peg] The largest component of plants is water. 80 to 90% of water is the growing tissue part of the plant, lower water percentage parts are the woody, between 45 and 60% by weight of the water. Transporting minerals acting as a solvent and carbohydrates dissolved. Excellent solvent due to its unique chemical properties. A reactant in many chemical reactions throughout the plant. Oxygen we breathe everyday is the result of water acting as electron in the reaction of photosynthesis. Maintaining pressure in the plant so the leaves are literally inflated is an important role of water, as wilted plants is a lack of water. The water pressure is necessary for cell enlargement, growth and maintenance. [John Peterson, 2010] The net movement of atoms or ions of a higher concentration to a lower is diffusion. Until a state of equilibrium, diffusion will continue. Temperature, molecule density are the affect in which diffusions rate is, occurring through the stomata into the atmosphere. Through a sem i permeable membrane, the diffusion of molecules. Pressure can prevent osmosis. The minimum pressure required for the fluid to be prevented from moving due to osmosis is call osmotic potential. Until the osmotic potential is balance fluid will enter the cell via it. To help keep the plant cell turgor, any water gained by osmosis is kept. As a result of water entering the cells vacuole developing against the wall is turgor pressure. The water potential is made up by the pressure potential combined with the osmotic potential. Water will move from the cell with higher water potential to the cell with lower water potential if there next to each other. Water moves due to the soils higher water potential than the roots and plant parts. The plant will die if there is no net movement in the plants. The loss of water via osmosis is plasmolysis and the shrinkage of protoplasm. If the cell is placed in fresh water this process can be reversed, as the cell is allowed to regain turgor pressure. Permanent damage can occur to the cell. Alive or dead tissue, swelling is imbition. It can swell to several times their original volume. Minerals, cellulose and starches in suspension, attraction highly polar molecules is due to this. The initial germination of the seeds is this swelling process. Movement energy of substances is active transport. Enzymes and a pump in the plasma membrane are required for this process. ATP molecules energize the face. [Biology online, 2010] Transpiration is where 90% of water that enters the plant is loss. Through the leaves is the loss of water vapour, this is transpiration. Loss if water through the cuticle is less than 5%. Not just for the pressure reason, vital to plant life is water and the cellular activities that occur in water molecules presence. The internal plants temperature is regulated by water. From the smallest root all the way up to the smallest leaf is the xylem pathway, internal plumbing system paired with phloem. The plants water needs and resources are maintained in the nutrient transportation system or internal plumbing. Columns of water in the plant form as the water molecules adhere to the xylem and tracheids walls and vessels to cohere each other allowing an overall tension. Water that enters the roots via osmosis, water content from the soil travels up these columns. Enough force to transport water through the plant is the water potentials of the soil and the stomata, from bottom to top. Externa l input is the minerals in the soil, affects the growth rate and quality. Hydrogen, carbon, nitrogen, potassium, iron, calcium, cobalt, zinc, sulphur, sodium, manganese, chlorine, oxygen, phosphorus, molybdenum and boron are essential mineral in the plants growth. Minerals vary from plant to plant in which helps them to survive. If the soil is lacking these nutrients and fertilizer isnt used to compensated, the plant will demonstrate mineral deficiencies symptoms. The ratio of nitrogen, potassium and phosphorus compensate the deficiencies. [Biology online, 2010] 2.0 Hypothesis Microwave radiation water will affect the plants growth. Boiled water will have minimal impact on the plants growth. 3.0 Aim To investigate the effect of microwave and boiled water on plants. 4.0 Materials Used Gardening spade 4 black P.E.T pots Searles real premium potting mix Microwave Oven Boiling jug/kettle 2 petunia x hybrid 2 Calendula officinalis Pen and Paper Ruler Gloves 2 measuring jugs 5.0 Method Potting Plants: Group names and plant type experiment were labelled on the pot. Pot was half filled with potting mixed. Plant was removed from seedling tray. Roots of the plant were spread out. Plant was placed into the pot. Pot was then filled with soil surrounding the plant and compacted. Steps 1 to 7 were repeated for each plant. Measuring Plants: Plant height was measured from the base to the highest point and recorded. Number of flowers and buds on the plant were counted and recorded. Stems of the plant were counted and recorded. Heating Water: Measuring jugs were labelled, boiling water and microwave water. Kettle was filled with tap water and boiled. Glass proof jug was filled with tap water. Jug was placed in microwave for approximately 2 to 5 minutes on high. Water was left to cool. 500ml of both boiled and microwave water were measured out. 1 of both the boiled and microwave experiment plants was watered. Steps 6 and 7 were repeated for the remaining 2 plants. Each week the method of heating the water measuring were carried out recording the plants development and growth. 6.0 Discussion The results of the experiment showed the aims outcome. Two plants Calendula officinalis and petunia x hybrid were tested for the affect that boiling water or microwaving it had up it. The stimulus was that microwaving water altered the DNA affecting plants. The water travel up the transport system of the plants, known as the xylem like a circulatory system. This is how the water and the dissolved nutrients throughout it is dispersed throughout the plant. If microwaving water alters its DNA and affects the nutrients which dissolve itself from the soil, the reason it affects the whole plant is due to its transport system. The plants werent affected that much by the two different waters, although the microwave marigold wilted and died. However there shouldnt be much difference between the boiled and microwave water. The hypothesis was based upon the stimulus of the experiment stating, microwave radiation water will affect the plants growth. Boiled water will have minimal impact on the plants growth. Although the results didnt support the hypothesis, as there wasnt any major difference between the boiled and microwave petunias and marigolds. Although the microwave marigold welted in our experiment other groups may have had boiled plants that welted. The variables would have been the reason as to why we received the results we did. As there was no fertiliser added to the plants and some of them demonstrated the characteristics of lacking nutrients, as fertiliser can assist in this and supply the plant with the nutrients to help its deterioration the plants werent helped. The dying plant couldve have been easily prevented if a substitute nutrient like fertiliser was given to it. Many errors throughout the experiment can be improved. When potting the plants the soil could have been compacted more so there were no air pockets and the water soaked in more. It also wouldve prevented the plants to die. Measuring the data, could have been more accurate by having more than 3 standard measurements, things such as the plants width could have been measured and the plants weight. The standard error ranges which mean the way in which every group maintained their plant was different and play a major affect on them. Such as accidently pouring the wrong water into the incorrect plant would have affected the outcome even though there shouldnt be much of a difference between microwave and boiled water. The environment in which the plants were in also affected them as they were open and exposed to rain and bad weathers. Many things of the experiment could have been improved to get a more accurate result. 7.0 Conclusion The hypothesis wasnt supported nor was it wrong as there wasnt a massive difference between the microwave water and boiled water results, it seems that the microwave water plants were growing better than the boiled plants, although only by a minimal amount. The results can lead to further experimentation upon humans and wether microwaving makes us susceptible to cancers and harmful diseases. Tests on animals and if over a period of time that microwave radiation can affect you and deteriorate the body. Does microwave radiation alter foods DNA and prevent our bodies from registering it. The experiment has answered the hypothesis and reached the aim, it has also left many further possible investigations about microwave radiation and its affects. 8.0  Acknowledgements I would like to acknowledge the year 10 biology class, Mr. Fesuk the teacher, Ms. Mason student teacher and my group buddies; Caitlin, Dorine and Shadae.

A Christian View of Suffering Essay -- The Value of Suffering

The concept of suffering plays an important role in Christianity, regarding such matters as moral conduct, spiritual advancement and ultimate destiny. Indeed an emphasis on suffering pervades the Gospel of Mark where, it can be argued, we are shown how to "journey through suffering" (Ditzel 2001) in the image of the "Suffering Son of Man" (Mark 8:32), Jesus Christ. Although theologians have suggested that Mark was written to strengthen the resolve of the early Christian community (Halpern 2002, Mayerfeld 2005), the underlying moral is not lost on a modern reader grappling with multifarious challenges regarding faith in the face of suffering. In his article "A Christian Response to Suffering", William Marravee (1987) describes suffering as an "experience over which we men and women continue to stumble and fall". The way we view God is crucial to the way we view suffering according to Marravee, who delineates the disparity between a view of God as an ‘outsider’ and the biblical image of God – where God is an ‘insider’ who suffers with us in our struggle. This essay seeks to explain the Christian view of suffering and the purpose suffering can have in our lives. Suffering is an individual's basic affective experience of pain or distress, often as a result of one’s physical, emotional or spiritual circumstance (Stanford Encyclopaedia of Philosophy 2006). Suffering can be classified as physical; for example pain caused by a dislocated knee, emotional; for example one’s grief over the death of a loved one, or spiritual; which is described as the state of being separated from the blissful nature of your divine self (soul). To suffer physically or emotionally is often unavoidable; however it can be argued that spiritual liberation... ...s distributed in Theology 101 at the University of Notre Dame, Fremantle on 22 April 2008.

Family Honor

Family honor is romeo and juliet is represented by the constant attempts to preserve family pride from both houses. This defense and pride causes many deaths and deeper problems that are passed down from generation to generation. In the first scene of romeo and juliet, the montagues and capulets come across each other, and because of the deep rooted hatred they have for each other's fmilies, they taunt one another and begin to fight. This fight worsens the already tarnished relationship the two houses share. Tybalt, a capulet, holds a strong place in defending his family's honor. It is so strong that he even enjoys it. Like Tybalt, the Montegues are fueled by their hatred for one another. What they don't realize is that this hatred only challenges each other's family honor. Family honor is not always such a negative thing. This can similarly occur outside fiction as well. In my family, there has been little representation of family honor. For example, moving around at such a high rate, we have been unable to develop feuds with other families. There were bits of family honor in my life. At school I was against telling anyone details about what was going on in my home life in an attempt to protect and defend my family's honor. This often was unsuccessful. Though, the type of family honor show in my life differed from the family honor shown in Romeo and Juliet. All in all, there is a distinct representation of famly honor in Romeo and juliet. This honor can also be shown in real life. This completely depends on the family and what family honor means to them. For me, family honor is not a huge factor in my life. This does not mean I do not have family pride. I cannot relate much to romeo and juliet.

Internet safety securityn privacy Essay

Introduction Microsoft has established partnership with American Academy of Pediatrics (AAP) in order to ensure online safety of children. This program provides guidelines for family safety and to protect children from developing psychological disturbances on social issues. AAP has a vast number of pediatricians in U. S. and it has second place as largest physician organization in the world which is promoting health and welfare to all children. Microsoft company which is a giant in computer software predicts that future generation of children required to possess extensive knowledge about Internet whereas, it should be lead by limitations of dos and don’ts on Internet browsing, which if not guided results in adverse impact both for parents and children. In this effort, AAP records a total of 96 million of school-age children per year and apart from promoting health care, AAP would also provide Internet safety measures for children. â€Å"We are pleased to see that the AAP and its members are striving to make Internet safety education a part of routine clinical care for children,† (Adrienne Hall, Senior Director of Trustworthy Computing at Microsoft) Microsoft has several guidelines for each age group. Viz. , using family contracts, 10 things to teach kids, computer security tips for students, steps to improve family’web security, minimizing risk from online predators, a bank of tips and tools to help parents and a video to teach kids how to be safe online. In fact there are many points that have to be noticed by children before entering online surfing. First and foremost, parents must be present while children are online and secondly, identify the purpose of surfing such as whether it is for the purpose of education, online games, chatting, shopping or for any other purpose. Thirdly, encourage children to enter through search engines, explaining the importance of finding good sources of information for education purposes, or directly by having an accurate web site address / URL . This enables children to click on a particular link that is required for further information. For instance, children above the age of 6yrs usually are quick to learn about online skills and enjoy playing online games. In such case, parents must take initiative to find a web site which contains free online games which are both educative and entertaining viz. , math games, puzzle games, doll games and many other sport games. Parents must explain that by typing â€Å"online games† in google search engine a plethora of games websites are displayed which are good and entertaining for children. Children are very smart than parents, with the fact that anything explained once is remembered and from the very next minute, children pick up so fast in learning concepts. Therefore, it is the responsibility of parents and teachers to teach online safety measures to children for the health and benefit of children. Step by step guidance is what is required for children instead of blackboard teaching. Teaching through videos, online training are some of the best methods to teach children how important it is to tread safely on Internet. There must be a friendly and warm atmosphere at the time of parents participation with children while teaching internet skills. Many a times, children do not agree or parents disagree with the online surfing. In such instance, rules must be framed as a formal contract that would be signed by both parents and children. In this manner, children would be compelled to listen to what parents teach about online skills. Apart from this open discussion, also brings good results with the fact that, when parents ask questions about Internet surfing, children get encouraged and begin to provide a great amount of information which enables parents to realize whether children are entering any unacceptable web areas or zones. There are quite a danger zones that harm children to the developing personality especially, information on weapons, forbidden web sites for children age and above all harmful images that trigger the emotions of innocent kids. Even chatting rooms have to be checked by parents, with the fact that at times, net friends provide false age and false information whereby children begin to build friendship with the above age group and ultimately fall prey as a victim to the net criminals/hackers. Children are even motivated to disappear from parents and especially in western world, parents suffered a great loss for not being aware of Internet in the primary stage of its launch. With some of these negative effects, Microsoft has even designed a code of conduct that must be signed between parents and children which is reproduced as below: â€Å"Online code-of-Conduct Contract. I will: Talk with my parents to learn the rules for using the Internet, including where I can go, what I can do, when I can go online, and how long I can be online ( ___ minutes or ___ hours). Never give out personal information such as my home address, telephone number, my parents’ work address or telephone number, credit card numbers, or the name and location of my school without my parents’ permission. Always tell my parents immediately if I see or receive anything on the Internet that makes me feel uncomfortable or threatened, including e-mail messages, Web sites, or even anything in the regular mail from Internet friends. Never agree to meet anyone in person that I have met online, without my parent’s permission. Never send pictures of myself or other family members to other people through the Internet or regular mail without first checking with my parents. Never give out my Internet passwords to anyone (even my best friends) other than my parents. Not do anything online that could hurt or anger other people or that is against the law. Never download, install, or copy anything from disks or the Internet without proper permission. Never do anything on the Internet that costs money without first asking permission from my parents. Let my parents know my Internet logon and chat names, listed below: _____________________ _____________________ _____________________ _____________________ Name (child) _______________________ Date ____________ Parent or guardian _______________________ Date ____________ Several hours of browsing may also be harmful to the sensitive eyes of children which is why there should be a protective screen on computer monitor, otherwise there is every possibility of backache, development of eyesight, and even dark circles around eyes. It is important to take note here that children should be instructed to blink eyes every second and staring at web sites while playing games or visiting web sites without blinking eyes, causes lot of eye sight problems. Conclusion Internet is truly benefiting to children wherein children are educated at a fast pace as never before through blackboard teaching whereas measures of care would yield good results.
