Australian Aboriginal Art Essay
The aboriginal people mainly used ochre for artworks, such as on rock, wood, bark and the human body.Ochre is mined from particular sites. It is a special type of rock thatââ¬â¢s heavily coloured because of the iron oxide contained inside, and comes in a variety of colours: yellow, white, red, purple (it is identical to red ochre chemically but of a different hue) and brown. It could be used on rock (cave walls, or just big rocks), wood (shields, log coffins, etc.), bark and skin, and artifacts. To get the paint from ochre rocks, one simply needs to find a rich coloured rock, ground it up, and add oil.Other materials such as charcoal and plant colourings were used to make black and dark green. Twigs, fibres and fingers were also used to get different strokes of paint, similar to the use of paintbrushes. Art is central to the Aboriginal life. It can be made for political, social, utilitarian and didactive purposes, and is inherently connected to the religious domain. Art is also a means by which the present is connected with the past and the humans with the supernatural. Art also activates the powers of the ancestral beings, expresses individual and group identity and the relationships between the land and the people. It was not until the eighteenth century, when the Europeans came to Australia, that Aboriginal art stopped being made only to fulfill traditional cultural needs, and this has only remained the in the case in varying degrees since. Contemporary Aboriginal Painting Methods In the 1930s, artists Rex Battarbee and John Gardner first introduced watercolour painting to an Indigenous man, who later used to create landscape paintings and were immediately successful and became the first indigenous Australian watercolourist. The word ââ¬Å"contemporaryâ⬠means modern or of the present time. Contemporary aboriginal paintings have adapted the usage of canvas and acrylic paints. Even though these arts still uses the traditional styles and symbols, the methods are a bit different. It is a mixture of the traditional and the modern culture. The main reasons that the European painting materials began to be popular so quickly is because using acrylic colours and canvas saves a lot of time for them and at easy to sell. You canââ¬â¢t really be expected to bring a big boulder to sell! Of course, even so, some artists still paint using the traditional methods. Different artists from different regions create different artworks because of their different surroundings and understandings. But even though their artworks are different, their subjects are all the same: Dream time. Aboriginal paintings and drawings are created to show how they live and how they think the world is made. Even though the materials changed, it doesnââ¬â¢t change the subject. Some paintings also show the aboriginalsââ¬â¢ beliefs, but they are sacred to the tribe. These sacred paintings and drawings are only allowed to be viewed by the tribe and nobody else. 2 Contemporary aboriginal artists: Albert Namatjira was an Australian artist. He was an Indigenous Australian of the Western MacDonnell Ranges area. He is perhaps one of Australiaââ¬â¢s best known Aboriginal painter. He was famous for his watercolour Australian outback desert landscapes, which were not in the symbolic style of the traditional paintings, but very detailed and colourful. Another is Barbara Weir. She is an Australian Aboriginal artist and politician. Her paintings include representations of particular plants and dreamings, inspired by deep Aboriginal traditions. She uses two distinctive stylistic conventions, which are linear and dot painting.

Biochemistry and Technology Essay
What specific topic did you choose to research and evaluate? (2 points) -I chose genetic engineering/recombinant DNA technology/transgenesis of biotechnology to research and evaluate because that interests me the most, personally. List the resources that you used in your research of your topic. (3 points) ââ¬â I used sites such as, wikipedia.org, and slideshare.net. Describe, in a few paragraphs, the biotechnology that you researched. How is it currently being used and/or what are the hopes for its use in the future? (10 points) -Genetic engineering is an area in biotechnology that induces cell alterations in any kind of organism. It is based on artificial manipulation and transfer of genetic material from one organism to another. Basically the cells coded in with the new genetic information will pass those selected traits on to their offspring. Genetic combinations might be useful but not often found in nature. Genetic engineering now a days, is used in medicine to produce insulin and growth hormones, for those who lack it. The genes in humans are isolated using enzymes produced by bacteria which cleave DNA at specific base pairs, and then inserted into a a virus. The virus then is inserted into the bacteria DNA, ten the bacteria produces the hormones, which are then collected and given to patients who most need them. The hope for genetic engineering is soon a cure can be found for diseases by either inserting a corrected gene or even performing a genetic surgery. Currently many pregnant women like to have the fetuses screened for genetic defects so it can allow them and there physician to prepare for the arrival of the child who may need to have special needs. Describe the positive aspects of this biotechnology, being as specific as possible. (5 points) -One possible benefit for genetic engineering is is that with gene therapy, a fetus a genetic defect could be treated and even cured before it is born. Specific traits or characteristics can be inserted in a species, for example pest resistant genes inserted into crops to enable more crops to be harvested. Artificially produce vital hormones or proteins that are essential by inserting the coding genes into bacteria cells.â⬠¨ Describe the negative aspects of this biotechnology, being as specific as possible. (5 points) -Genetic pollution occurs where the artificially produced species reproduce at a higher rate compared to the wild species present and cause extinction. Species that are produced have side effects such as a short life span, prone to diseases and mutations and physical defects. Expensive and advance technologies need to produce and maintain genetically engineered species. Hybrid species created may harbor new statins of diseases or viruses that is produced from the altered genes. Based on your research, what is your conclusion about whether or not this biotechnology should be used? Be sure to explain your answer. (5 points) In my opinion, I think biotechnology can benefit us all in a lot of different ways, but only if we use it right and only if we are really in need of it. For example, I think genetic engineering could help actually save a lot of lives and troubles that one might have when born. If treated right, a disease or disorder can be cured before one is born.

A look at the affect names have on the characters of Fifth Business By Robertson Davies
A look at the affect names have on the characters of Fifth Business By Robertson Davies What's In A Name?"What's in a name? That which we call a rose by any other name would smell as sweet." (Romeo and Juliet, Act II Scene ii) A person's name can shape a large part of who they will be. In the novel Fifth Business by Robertson Davies, the names of the characters seem to directly reflect some of the characteristics of that individual. The new names for those characters that were twice born better reflect who those characters are. Other characters, such as Mary Dempster and Lisolette Vitzliputzli's names provide some insight into their characters.After the war, Diana renamed Dunstable. His new name, Dunstan, better reflects who he is because of the many similarities between himself and Saint Dunstan. "Saint Dunstan was a marvelous person...mad about learning, terribly stiff and stern and scowly, and an absolute wizard at withstanding temptation"(Fifth Business p.90). Dunstable Ramsay had always been interested in learning, as evident from his childhood job at the local lib rary, his education at the University of Toronto as well as his lifelong passion for studying saints.English: Tomb of the Virgin Mary. Altar.jpg à Ã'Æ'Ã' ...As a child, Dunstable would read about magicians and had a particular interest in saints. Therefore, it is entirely appropriate that later in his life he be named after a saint. Dunny also had many other similarities between himself and Saint Dunstan; many things during Saint Dunstan's life can be compared to incidents in Dunny's life. When Dunny was young, he was ordered by his mother to help Mary Dempster. Similarly, Saint Dunstan, "With his parent's consent ... served in the ancient church of St. Mary." Accordingly, the name Dunstan is fitting to the character of Dunstan Ramsay.Conversely, Percy Boyd Staunton renamed himself during the war. His new name, Boy Staunton is entirely...

WTO effect on Taiwan Essay Example | Topics and Well Written Essays - 1500 words
WTO effect on Taiwan - Essay Example (Antkiewicz, 2004) In other words, the more internationalized the financial markets and the more liberalized the capital account, the more challenges the autonomy of monetary policy have faced. In fact, financial internationalization underlay both the Latin American financial crisis happening earlier and the East Asian crisis a few years ago. Experts and scholars, by drawing important lessons from financial crises, have, retrospectively, advocated a progressive approach rather than an aggressive one to financial internationalization. They have singled out relaxation of capital account controls as the bottom-line defensive measure and have even viewed a certain degree of re-regulation as necessary in the aftermath of financial liberalization and internationalization. (Cai, 2005) By doing so, the negative impact of rapid and large-scale international capital movements on a countrys economy can be minimized. Generally speaking, financial liberalization includes cross-border flows of funds, personnel and commodities. In addition to opening the capital account, it also includes expanding offshore business, establishing foreign exchange call-loan markets, and allowing foreign bank operations and branches. The following phenomena, which are independent in itself but not exclusive of each other, illustrate the connotation of financial internationalization: 1) The restrictions on the currency exchanges and other international financial activities of residents and non-residents (including individuals, corporations and financial institutions) are relaxed Domestic banks are allowed to establish overseas branches. Domestic corporations can raise funds by issuing corporate bonds overseas or by investing overseas. Foreign banks and corporations are also permitted to conduct reciprocal financial businesses locally. (Weixing, 2006) 2) International capital movements

Understanding the Court System Essay Example | Topics and Well Written Essays - 1250 words
Understanding the Court System - Essay Example This paper endeavors to help in understanding the United States of America court system. To achieve this, the paper will discuss the case of Riley v. California heard in the Supreme Court. The Supreme Court determination in this case considered two individual cases. Both cases involved cell phone searches during arrest without a warrant of search. One case involved David Leon Riley stopped in San Diego by a police officer in 2009 for having expired car registration tags (Harvard Law Review, 2014). The police towed the vehicle and searched it. During the search, they discovered two handguns hidden under the boot of his car. The police seized his phone without warrant and searched it. The phone records showed that Riley was part of a gang known as the Lincoln Park gang the evidence from the phone also placed him at a crime scene three weeks before and his made the prosecution used this evidence to build a case of assault and attempted murder against Riley (Harvard Law Review, 2014). During the trial, the judge upheld that the evidence from Rileyââ¬â¢s Smartphone was admissible because it fell under the exceptions provided by search-incident-to-arrest provisions. The trial led to the conviction of Riley and the California court of appeal upheld this ruling (Harvard Law Review, 2014). The second case involved Brima Wurie arrested by a police officer who observed him participating in drug trade. During the arrest, the police officers confiscated two mobile phones from him (Harvard Law Review, 2014). After searching the call log, they determined the location of a caller and traced it to a location where they seized drugs, firearms and cash. The prosecution charged Wurie with drug and firearm possession. The district court declined to declare the evidence from the mobile phone as inadmissible since the police acquired it without a warrant. However, the first circuit court overturned the decision by the district court citing that mobile

Township of Twisted Water Boundary Assignment Example | Topics and Well Written Essays - 1500 words
Township of Twisted Water Boundary - Assignment Example The process used and the allocation limits chosen were published in managing the groundwater resources of the Township of Twisted groundwater management strategy. To decide on the allocation limits, results from an earlier groundwater model (GRFAMOD, Dodson 2001) and the information gathered from the environmental water requirements assessments (SMEC 2001), was used. The GASFAMS groundwater model estimated the recharge, through flow, discharge and storage characteristics of the flow system. The groundwater model simulated a number of recharge scenarios to determine how much water could be sustainably abstracted from the system. The department follows a standard planning process when developing an allocation plan. A component of this process is setting allocation limits and the management regime. For the Township of Twisted area, we set allocation limits in accordance with this process. The yield estimate tells us how much water can be taken from a resource for use and what volume or flow is needed to maintain the ecological and social values, within and downstream of the resource. We also consider management considerations in our decision, such as reliability of supply, current use, future demand and the effects of water abstraction and use on water quality. The department applied this process to the Township of the Twisted alluvial aquifer to determine the allocation limits. An allocation limit is the annual volume of water set aside for consumptive use from a water resource. This includes the water available for licensing and the water set aside for uses exempt from licensing, such as stock and domestic. For administrative purposes, the allocation limit is divided into three groups of components: Involving the community is an important part of the planning process. Extensive consultation should be done to ensure setting the right management approach for the area.Ã

Urban Areas Modify Climates Essay Example for Free
Urban Areas Modify Climates Essay Urban areas climate is often significantly different to the surrounding rural areas, this is why urban areas are often described as having their own ââ¬Å"micro climateâ⬠the differences in urban climates are due to number of different factors. Urban areas often experience a phenomenon known as a heat island, this is a zone of hot air around and above an urban area which has higher temperatures than the surrounding rural areas consequently cities tend to be warmer than rural areas and the temperature becomes lower progressively as you move towards the rural area with the highest temperatures being in the city centre. Heat islands form due to a variety of factors which are present within cities and not commonly found in rural areas, firstly building material such as concrete and tarmac absorb large quantities of heat during the day (due to their black colour) and when temperatures are cooler (nigh time) the heat is released gradually warming up the surrounding area, this is why the effects of the heat island are more visible at night time because the city remains warm whilst the rural areas are much cooler. There are a large amount of buildings with glass windows within the urban areas, these have a high reflective capacity and reflect heat towards the streets were it is absorbed. Another factor influencing towards to the heat island formation is the heat energy being emitted from industry due to the combustion of fossil fuel which releases heat, domestic heating also contributes towards this, this heat energy warms up the air within the urban area contributing to the dome of warm air which is the heat island. The emission of hygroscopic pollutants from cars also acts as a condensation nuclei leading to the formation of cloud and smog which traps radiation within the area. Precipitation rates are also significantly different within rural areas, research shows that rainfall is generally higher within the city than surrounding rural areas, a reason for this could is due to the fact the heat island ultimately means temperatures are higher therefore lower pressures will be encouraged to dev elop above the city, also it means Evapotranspiration rates will be higher within the city causing more cloud formation. Convection rainfall is much higher within the city and this is because the heat island enhances convectional uplift, the city also produces large amounts of water vapour from industrial sources this also means that humidity levels within cities are usually higher The occurrence of Fog is dramatically higher within urban areas, the great increase in the amount of fog within cities is in accordance with the industrialisation of the city, e.g. In London 1700 there was 29 days of fog but by the 1800 (industrial revolution had occurred) there was over 50 days of fog, this statistic shows that the amount of fog is influenced by the amount of industrial activity within a city. The reason behind this is the fact that cities have a higher average number of particles within the air (due to industrial activity releasing pollution) these particles act as a condensation nuclei and encourage fog formation (usually under high pressure conditions) when pollutants become trapped within the lower atmo sphere water vapour can condense around these particles and cause smog to form. These were common in 20th century London. Smog can have devastating effects and can cause serious respiration problems for people and trigger diseases such as emphysema, more recently photochemical smog has been developing this is due to polluting gases such as nitrous oxides and carbon monoxide react with sunlight to produce a cocktail of harmful gases which can cause devastating health effects. Air quality within urban areas is also dramatically different than surrounding areas. Within cities there is a significant amount of pollution, there are different types of pollution and they have different effects. Suspended particulate matter is solid matter within the urban atmosphere such particles are usually less than 25micrometers in size and cause problems such as fog/smog, respiratory diseases, soiling of buildings. Sulphur dioxide is usually released from combustion of fossil fuels causes a hazard known as acid rain (due to its acidic nature) and this can corrode away at buildings it also contributes to respiratory disease s Carbon monoxide is also released from incomplete combustion of fossil fuels and is a poisonous gas that prohibits haemoglobin within the blood to uptake oxygen, therefore it is potentially life threatening. Consequently due to all the pollutants the number of ââ¬Å"blue sky daysâ⬠were the sky is visibly blue can be significantly reduced consequently reducing the amount of sunlight upon the city, there have been policies introduced in cities worldwide to reduce pollution levels and increase the number of blue sky days. The serious effects of poor air quality can be perfectly illustrated with Beijing were the public wear masks to protect themselves from the poor air and serious efforts have been made to cut down on polluting sources. The urban layout of buildings of various different sizes vastly affects the wind pattern in the upper atmosphere; there are effects on wind speed, direction and frequency. The surface area of cities which is very uneven exerts a powerful frictional drag on the air moving over and around this creates strong turbulence giving rapid and abrupt changes in both wind direction and speed, consequently average wind speeds are lower within the city. High rise building significantly disturb airflows over urban areas, they deflect and slow down the upper atmosphere winds, and this can creature strong vortices and eddies. These fast turbulent winds can become funnelled in-between buildings producing a venturi effect this can swirl up litter and make walking down pavements difficult In conclusion urban areas can significantly influence their climate and cause it to be very different compared to surrounding rural areas, urban areas cause numerous amounts of changes in the climate surrounding them and cause higher temperatures, higher precipitation rates, effect the air quality and completely disturb the upper atmosphere wind pattern.
