Trace Evidence Essay Example | Topics and Well Written Essays - 750 words

Trace Evidence - Essay Example The main biological molecule of target for forensic analysis is deoxyribonucleic acid (DNA), which is present in all cells of all organisms. Biological evidences at the scene of the crime thus serve as essential resources for DNA that could be employed in the forensic analysis of a criminal case. DNA from cells of both the victim(s) and the assailant(s) may be extracted from biological materials that are collected from the crime scene. With the proper application of molecular biology techniques, DNA could be extracted from forensic samples and subjected to DNA analysis. The main procedure employed in the analysis of DNA is the polymerase chain reaction, which is an enzymatic process that generates several copies of DNA based on the sequence of a template DNA (Giardina et al., 2009). The reaction involves a bacterial enzyme that has the capacity to withstand high temperatures that are required for DNA amplification. The amplified DNA fragments are then subjected to a separation assay called agarose gel electrophoresis, which mainly involves running the DNA according to its molecular weight in the presence of an electric field. The fragments are then expected to migrate through the gel and stop at its corresponding molecular size. Both the victim and the suspect's DNA samples are subjected to the polymerase chain reaction, as this will allow the identification of the source of each biological material that is collected at the crime scene. The most common DNA sequences involved in forensic analysis are the short tandem repeats (STRs), which are usually between 20 to 100 nucleotides in length and highly variable in the human population. It is thus expected that every individual in the human society may carry a different sequence in the STRs and the only other individuals that could have a match with a person are those of his parents or his children. Other biological materials that could be collection from the scene of a crime include insects, as well as pollen, that may be present on and within the body of the victim. It should be understood that a human body immediately undergoes the process of decomposition within the first hour after the individual dies. Insects deposit eggs within the first few hours of death and these develop into larvae, or maggots, that are often observed in a body that has been left in the open for a couple of days (Nazni et al., 2008). Forensic entomology allows the researcher to identify the species of the larvae, as well as to determine the age of the larvae in terms of developmental stages or instars. This estimation plays a critical role in determining the time of death of the victim. The presence of pollen on the body of the victim of a criminal case may also provide information on whether the victim was murdered at the site or was otherwise transferred from one place to another. Every place has a specific collection of pollen, and this is mainly based from the types of plants and trees that are present in the area. If a crime was performed within a forest, then the pollen that could be collected on the body of the victim should be of those that were derived from the plants and trees of that same forest. If the pollen collected from the body of

The Life and Writing Style of Mark Twain Essay Example | Topics and Well Written Essays - 1750 words

The Life and Writing Style of Mark Twain - Essay Example By employing humor in his works, Twain was able to expose the bitter, realistic attributes of of society, religion and humanity. In fact, Twain’s two masterpieces â€Å"The Celebrated Jumping Frog of Calaveras County† and â€Å"Letters from the Earth† demonstrate Twain’s two kinds of humor. Mark Twain was born in 1835 as Samuel Langhorn Clemens, a man who had had numerous careers before he even turned 30 from being a journeyman printer to being a riverboat pilot. When he found a job at a newspaper company, he immediately adopted a pen name – Mark Twain. It was in 1865 when he gained overnight fame from his first masterpiece – a short story entitled â€Å"The Celebrated Jumping Frog of Calaveras County,† and also a piece of work that practically displays Mark Twain’s typical writing style (Schultz). Most of Twain’s writings had in them local color realism and mainstream realism. For â€Å"The Celebrated Jumping Frog of Calaveras County,† Twain employed local color realism and mainstream realism, while for â€Å"Letters from the Earth,† the author used sharp sarcasm and wit. In â€Å"The Celebrated Jumping Frog,† local color realism can be proven by Twain’s use of the dialect of the deep south. The vocabulary used by the character Simon Wheeler in short story is typical of local color realism. In the story, Wheeler uses â€Å"feller† instead of fellow, and contractions like â€Å"reg’lar† and â€Å"solit’ry† (Twain, â€Å"The Celebrated†).... ost curious,† â€Å"she don’t,† which is supposed to be â€Å"she doesn’t,† and â€Å"ketched† which stands for â€Å"catched† but which is supposed to be â€Å"caught.† (Twain, â€Å"The Celebrated†). Moreover, mainstream realism is also used in â€Å"The Celebrated Jumping Frog† as Twain mentions real life events like gambling and cheating. Both local color realism and mainstream realism attribute the realistic aspect of any literary work during the era of realism in literature. On the other hand, Twain employs sarcastic humor in â€Å"Letters from the Earth.† In fact, the whole story is heavily peppered with sarcasm. One of these instances is in saying that â€Å"[man] believes the Creator is proud of him; he even believes the Creator loves him† when in fact He does not (Twain, â€Å"Letters,† I). In fact, the picture of man as otherwise arrogant and proud is what he means by the aforemention ed example. Twain was therefore trying to awaken people through his sense of humor coupled with realistic elements. Satan also mentions in his letters that although human beings place sexual intercourse â€Å"far and away above all other joys,† they have somehow forgotten to include it in their idea of heaven (Twain, â€Å"Letters,† II). This now addresses a confusing issue about sex. If human beings consider the act as sexually and physically pleasurable as it is stated in the Bible, then why would the idea of sex be excluded from one’s perception of heaven? Twain addresses this issue in â€Å"Letters from the Earth† (Twain). As an addition to sarcasm, Twain used religious references in â€Å"Letters from the Earth† but references to the government in â€Å"The Celebrated Jumping Frog.† The purpose is to instill humor. Through the characters of the archangels Michael and Gabriel and

Adoption of Renewable Energy Technologies in the United Kingdom Essay

Adoption of Renewable Energy Technologies in the United Kingdom - Essay Example A huge proportion of the world's energy resources come from natural gases, fossil fuels, and nuclear fuels. These types of energy sources emit harmful chemicals and residues in the atmosphere, on the soil and in various bodies of water, which are harmful to the environment. Recent studies estimate that the demand for energy will increase affectedly within the next few decades. Many scientists around the world agonize over the postulated insufficiency of natural gases which are now considered to be finite and unsustainable. Also, global environmental problems like global warming call for cleaner energy sources in order to preclude degenerative developments in the world's environmental conditions. The running down of United Kingdom’s vast energy resources, along with the forecasted escalation of the world’s energy consumption imperils its energy security. Jamieson 2 Sole reliance on fossil and nuclear fuels void its commitment to reducing energy consumption and cutting ca rbon emissions. The national government now turns to exploiting renewable energy sources that will increase energy supply. The adoption of renewable energy will also help in the decarbonization of the atmosphere using Carbon and Capture Technology. The Department of Energy and Climate Change’s Office for Renewable Energy Development exerts effort in order to understand how this transformation can be achieved and to discuss the possible barriers that may debar adoption of renewable energy. How to achieve development of diverse renewable resources The implementation of renewable energy technologies in the United Kingdom can â€Å"meet the target to deliver 15% of the UK’s energy consumption from renewable resources by 2020† (Department of Energy and Climate Change, â€Å"Renewable Energy†). There are eight (8) renewable resources technologies that will be used to generate at least 15% of the total energy consumption in the United Kingdom by 2020. These are the following: (1) Onshore wind; (2) Offshore wind; (3) Marine Energy; (4) Biomass Electricity; (5) Biomass Heat; (6) Air-source and Ground-source heat pumps; (7) Renewable Transport; (8) Solar and Geothermal Technologies. The national government should focus on the following measures in order to achieve these developments: 1. Enabling access to the grid. Deployment of energy generated by renewable energy resources cannot be completed without access to the grid. This can make or break the plan. The government must ensure that grids are supplied on all renewable energy sites in order to ease deployment actions. Jamieson 3 2. Making sure of a sustainable supply of bioenergy. Bioenergy is seen to possibly contribute almost half of the total energy production needed to meet the 15% target. However, matters pertaining to its sustainability may reduce the use of bioenergy. 3. Technological Advancement. A constant upgrade on the technical support is needed to elevate efficiency on the depl oyment of energy throughout the country. While tools and equipment used in some forms of renewable energy technologies are relatively advanced, others are yet struggling with having the comparatively outmoded technology.
