Fireworks combine art and science. Discuss the chemistry behind firework colors, including the mechanisms of color production - Essay Example 111). The production of basic firework entails one to have four chemical agents essential in the formation of the entire complex reaction. These reagents or requirements include reducing agents, oxidizers, binders, coloring agents and regulators whereby the latter undertakes the role of controlling heat (Ochiai, 2011). Binders in the production of fireworks ensure each reagent is in its place for various chemical reactions to take place as necessitated, hence produce the required color displays. Oxidizers in this reaction serve the purpose of availing the required oxygen essential for the combustion process (Ochiai, 2011). These oxidizing agents include nitrates, chlorates and perchlorates (Ochiai, 2011). However, their extent of releasing respective oxygen atoms varies greatly during the entire and complex reaction process. Key oxidation reactions resulting from these processes include, Upon the release of O2 in the atmosphere, it encounters with S and C, which act as reducing agents producing their respective gaseous oxides as well as heat. Produced heat in this case increases explosive power of the entire combustion process. Color production during fireworks comprises of two mechanisms, which are Incandescence and Luminescence (Helmenstine, n.d). In the initial mechanism, it refers to a light produced by heat changing into varied colors based on different temperatures that increase with heating. Successive colors produced by this light include infrared, red, orange, yellow and finally white though under effective regulation one can attain his or her distinct color (Helmenstine, n.d). In addition, one can utilize selected metal elements to increase the brightness of a firework, for instance AL, Ti and Mg commonly known to burn brightly at high temperatures (Helmenstine, n.d). Conversely, Luminescence refers to a light produced by external sources mostly

(business information system) DIRECT LINE reviews and system Essay

(business information system) DIRECT LINE reviews and system aquisition - Essay Example Beal’s (the IT director for the company) strategy the company focuses on building software systems in house rather than outsourcing the development. Therefore, according to his vision the company can do much better by developing products in house. It enables them to get a better understanding of the work domain and the exact requirements of the product. Similarly, in house development will also help in reducing non functional errors, as most of the performance related metrics would be known prior to the coding phase. On the other hand, recently the company has diverted from its long followed strategy of custom made in house products to buying vendor made products. Hence, the company has started to consider outsourcing as an option for the system development and acquisitions. The outsourcing of software products is proven from the fact that Mr. Beal purchased CRM software named Chordiant from a US supplier. Hence, the two system acquisition techniques by Direct Line are classified as in house development and outsourcing. Both have their pros and cons, their importance can only be justified when both the techniques are applied to a business problem. Sometimes it may seem feasible to adopt in house development while in others outsourcing might prove to be more efficient. There are numerous reasons for employing the in house development approach for software systems. These include efficient use of the programming and IT staff. By ensuring that products are developed in house the IT staff is not episodically involved rather they are involved throughout the development process and later in the support process. Other reasons include a better understanding of the problem domain and the associated work areas. Therefore, by developing systems in house the IT department can solve the problem more efficiently. Another benefit from in house development to the company is that the development is incremental and it can be easily integrated with the existing

The Study of Proteome

The Study of Proteome The breakthrough in the study of genomics has created a great impact for biological research. For instance, the complete genome sequencing accomplished for various model organisms such as bacteria, yeast and drosophila has been a key to understanding the diversity and functions in living system (Liebler, 2002). However, the gene products, proteins are playing crucial complex functions in sustaining the living system. Therefore, in order to acquire a clearer picture about the function of the living cells at molecular level, it is important to study the entire set of protein expressed by a genome, cell, tissue or organism throughout the cell cycle as known as proteome (Monti et al., 2005). This study of proteome is termed proteomics which is mainly focus on the identification of proteins, determination of the interaction between various proteins as a part of a larger network and outlining the 3D structures of proteins (Liu Hsu, 2004). According to Liebler (2002), the applications of proteomics comprised of mining, protein-expression profiling, protein-network mapping and mapping of protein modifications. These four principals then bring about the branches of proteomics which are the sequence and structural proteomics, expression proteomics, interaction proteomics as well as functional proteomics. i. Sequence and structural proteomics Structural proteomics is generally aimed at efficiently convert the gene sequence into 3D structural information which will then being used to facilitate the prediction of protein folding and functions afterward (Yee et al., 2002). 3D structure prediction and determination of proteins on a genome-wide scale are managed to provide substantial information in understanding the structure-function relationships of the particular proteins (Liu Hsu, 2004). The approaches commonly employed for this area of study are NMR (nuclear magnetic resonance) spectroscopy and X-ray crystallography. In a study done by Yee et al. (2002), structural proteomics of small proteins based on data of 513 proteins from five microorganisms is done by using NMR spectroscopy. Small proteins are more acquiescent for structure analysis primarily due to its solubility as protein aggregation appeared to be a limitation for structural proteomics (Yee et al., 2002). NMR evaluation of proteins is performed after ran through a series of cloning, expression and purification processes. The chosen targets for NMR screening by Yee et al. (2002) were single chain polypeptides with not more than 23 kDa molecular mass. PCR was involved to amplify the targets from genomic DNA. Subsequent cloning of the target proteins into vectors was then carried out. Batch Ni2+ affinity chromatography was done for the extraction of cells (Yee et al., 2002). Varian INOVA 500- or 600-MHz spectrometer was used to attain all the 1H-15N heteronuclear single quantum coherence (HSQC) spectra and the NMRPIPE software package was utilized to processed the data (Yee et al., 2002). The HSQC spectrum is to provide a diagnostic fingerprint of a protein. Twelve of the proteins were considered to be suitable for structure determination and have their 3D structures successfully analysed which were conserved without functional annotation (Yee et al., 2002). Among them, eight out of twelve were the members of uncharacterized cluster of orthologous groups (COG) or protein superfamilies. In order to know whether a 3D structure can be predicted, the sequences were submitted to SwissModeler to be analysed based on sequence similarity. ii. Expression proteomics Human Protein Atlas (HPA) launched by Swedish researchers in 2003 is a comprehensive effort in mapping the proteins expressed in the body’s tissue and cells according to the genes documented by Human Genome Project (Marx, 2014). HPA principally looked at the spatial distribution and protein-expression patterns of human proteins as well as comparing the protein expression between cancerous and normal tissues. The expression proteomics is a focus for proteome study which targets on measurement of the up- and down-regulation of protein levels as well to explore the protein expression patterns in abnormal cells for biomedical application (Monti et al., 2005). Approaches like mass spectrometry, 2D-gel electrophoresis and protein arrays are used in expression proteomics. Mazzanti et al. (2006) as done an investigation upon the differential expression proteomics of human colon cancer to look at the operative pathway of early stages of human colon cancer and to compare with normal colon tissue. In this case, they were using 2D-gel electrophoresis to observe the differences in protein expression at various differentiation levels. After the tissues were properly collected and homogenized, Western Blot analysis was carried out to evaluate the expression levels of the proteins and followed by 2D-GE. The differences in intensity of each spot and the normalized spot volume were calculated and statistically analysed. Matrix-assisted laser desorption ionization-time-of-flight mass spectroscopy analysis of tryptic peptides was performed to detect the differentially expressed samples processed by 2D-GE (Mazzanti et al., 2006). Lastly, a search through NCBI non-redundant databases and SWISSPROT was completed to identify the proteins. As a result, several proteins were found differentially expressed in colon cancer and normal tissue. Mazzanti et al. (2006) have obtained 11 and 15 proteins from healthy and cancerous tissues which were categorized according to the pathway they involved respectively. In addition, they also claimed that cancer tissues preferably utilize glycolysis due to selective repression of ÃŽ ²-subunit ATPase expression and limited substrate availability to mitochondria (Mazzanti et al., 2006). iii. Interaction proteomics Interaction proteomics emphasis on the elucidation of protein-protein interaction to which the multitude functions of proteins in association with individual components of proteome and the formation of multimeric complexes (Và ¶lkel et al., 2010). Frequently utilized approaches for interaction proteomics are like mass spectrometry (MS), affinity captured combined with mass spectrometry and yeast 2-hybrid techniques. Và ¶lkel et al. (2010) mentioned that characterize protein complexes from bacteria, yeast, mammalian cells and some multicellular organisms can be done by using tandem affinity purification-mass spectrometry (TAP-MS). TAP is functioned based on the dual purification of protein assemblies by sequential utilization of two affinity tags spaced by a TEV (tobacco etch virus) protease cleavage site (Và ¶lkel et al., 2010). TEV is a sequence-specific protease that cleaves a recognition site of seven-amino-acid (Glu-X-X-Tyr-X-Gln/Ser) which is rarely found in mammalian proteins (Berggà ¥rd et al., 2007; Và ¶lkel et al., 2010). This epitope-tagging purification strategy further improves the sample purification prior to protein identification by MS. In the first purification step, the TAP-tag protein is bound to specific column like immobilized Ig (Berggà ¥rd et al., 2007; Và ¶lkel et al., 2010). Retrieval of TAP-tag protein is done by adding TEV-proteinase. The protein complex is then immobilized by CBP (calmodium-binding peptide) of TAP tag to a second column, the calmodulin-coated beads in the second affinity step. This calcium-dependent CBP-calmodium interaction enables the elution of final protein complex for MS protein identification by means of calcium chelation (Và ¶lkel et al., 2010). The TAP purification of protein complex is independent of the availability of specific antibodies. It is used to accomplish large-scale protein interaction mapping of lower organisms and decode the smaller interactomes and signalling pathway in mammals (Và ¶lkel et al., 2010). However, this technique may not be able to identify low stoichiometric complexes, transient interactions or under-represented interactions occurred specifically in some physiological states of cells growing exponentially (Và ¶lkel et al., 2010). iv. Functional proteomics The objectives of functional proteomics are to characterize the biological function of unknown proteins, multiprotein complexes and descript the cellular mechanisms as well as signalling pathway at molecular level (Monti et al., 2005). Henning and Ilag (2003) stated that the protein functions assessment could be done based on the individual cell types and interaction of protein partners. Functional proteomics implement the concept that functional inactivation within the physiological environment of a targeted protein can be used to determine its function (Henning Ilag, 2003). Tools that are typically employed in functional proteomics include 2D-gel electrophoresis, MS, MALDI-TOF (matrix-assisted laser desorption ionization-time of flight) MS and affinity-based procedure. The affinity-based procedure is worked on the idea that a suitable tag of the expressed target protein can be used as a bait to fish out its partners from a cellular extract (Monti et al., 2005). Brookes et al. (2002) utilized a high-throughput two-dimensional blue-native electrophoresis in the study of functional proteomics for mitochondria and signalling pathway. As mitochondrial membrane proteins exhibit hydrophobic properties, precipitation is occurred in standard 2D gels during the first dimension isoelectric focusing. Thus, the 2D blue-native gel electrophoresis is used resolve this problem. The first dimension of 2D blue native gel electrophoresis involved the solubilization the membrane protein complexes into its native form. This is followed by the second dimension utilizing the sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-page) with its gel staining performed by employing a mixture of Coomassie blue G-250 and R-250. SDS-page is worked on denaturing the protein complexes and enables them to resolve into their component subunits (Brookes et al., 2002). A partial mitochondrial proteome map was then assembled by using MALDI-TOF MS coupled with tryptic peptide fingerprinting. This 2D blue native gel electrophoresis is found suitable for proteomic analysis of mitochondria proteins in which it could separate large amount of mitochondria proteins and large proportion of respiratory chain complexes as presented as the spots on the gel can be readily identified according to their position (Brookes et al., 2002). The functional associations between different respiratory complexes in mitochondria like cytochrome C, respiratory complexes III and IV can be interpreted from the gels. From this study, Brookes et al. (2002) suggested that the respiratory complexes are able to assemble into sub-complexes with limited functionality regardless of the presence of mtDNA encoded subunits.

Woody Allen :: essays papers

Woody Allen "A plethora of people have written about Woody Allen", John Lahr said "and they either like him or dislike him. But no one has yet managed, I think, to interpret him." Woody Allen has been revered as one of the brilliant artists of the twentieth century and at the same time called a pervert. His works have been called jokes but also masterpieces. Many critics have tried to explain why Allen writes the things he writes but not one has had success. The drive and brilliance of Allen has not been understood yet. Seeing his movies gives us two opposing views. One is the screwball comedian who is obsessed with death and sex while the other is the serious artist commenting on and criticizing our society. The latter view is more difficult to grasp but is nonetheless there. Through different film techniques Allen mocks our society and film industry without us even realizing. His most widely used technique to do this is the film within a film. In movies such as The Purple Rose of Cairo, Play It Again Sam and Hannah and Her Sisters Allen uses this technique to show us his opinion on a particular subject, and also uses it as a driving force behind his movies.The most notable use of film within a film in Allen?s movies occurs in, The Purple Rose of Cairo. The time is The Depression and the scene a small town. Cecilia (Mia Farrow) is the central figure in the movie. She is married to an abusive gambler and heavy drinker. To cope and escape her problems, Cecilia constantly goes to a nearby movie theater called The Jewel. There she spends hours on end watching movies, sometimes the same one more than three times. When she gets fired one day from her job, she goes to The Jewel and watches a movie called The Purple Rose of Cairo "at least five times" (Blake 117). On her fifth time watching the movie, Tom Baxter (Jeff Daniels) jumps out from the movie and enters the theater telling Cecilia that he has noted her faithful presence and is attracted to her. As they leave the theater together, the actors in the movie aimlessly wonder around bewildered by what had just transpired. Deeply concerned is the real life actor of Tom Baxter, Gil Shephard because this misfortune could "wreck his blossoming career"(Kauffmann 37). To add to the trouble, other cities have reported that the Baxter character has stepped out of The Purple Rose of Cairo in various theaters and has disappeared. Why would Woody Allen create such a unrealistic movie critics called "the most innovative

The Butterfly Effect Case Study

The Butterfly Effect Case Study How Narrative Is Used In The Butterfly Effect To Add Enjoyment For The Audience Narratives are used in â€Å"The Butterfly Effect† to add enjoyment for the audience in a number of different ways. â€Å"The Butterfly Effect† released in 2004 after 7 years being made, produced and recorded. This all began in 1997 and was a time consuming piece to begin with. The writers and directors â€Å"Eric Bress† and â€Å"J. Mackye Gruber† who previously written â€Å"Final Destination 2† which took in an average of ? 0,000,000 which shows that these two directors can write good story line making â€Å"The Butterfly Effect† and sure loved film. This can be justified by knowing and researching that â€Å"Final Destination 2† was nominated for four awards 2 of which were in â€Å"Best Story Line† in 2003 and 2004. This film has many institutions that have been used to represent this film. Using multiple institut ions like this is commonly known as a synergy or a conglomerate. This institute behind the film are â€Å"Icon†, â€Å"Warner Brothers†, â€Å"Newline Cinemas† and also â€Å"Film Engine Benderspink†. The producer â€Å"Chris Bender† who was newly producer for film like â€Å"The Hangover† and â€Å"I Am Number 4† Has made a big impact on the film â€Å"The Butterfly Effect† Also The other producers that have been producing the film alongside Chris Bender are as followed. A. j. Dix, Anthony Rhulen and JC Spink. These 4 producers up-to-date have never worked on the same film before The audience expectations are multiple genres of the film. Firstly a mystical type of film. This is given by the case of the DVD when we see the several layers of pictures that end up to a butterfly hence â€Å"The Butterfly Effect†. These layers are filled with the main star of the film, â€Å"Ashton Kutcher† and close ups of the human skull. This makes it look like there are problems with the mind and the physiological problems that this film or character is facing. Also another one is the fact that the people believe they are going to watch a film for all ages. But the 15 certificate was deserved for the twisted story line that this film is going on. Also whilst reading a review on IMDB. COM I have found out that people bought this film and watched this because they believed that it was going to be a calm film due to the name butterfly, which is one of the only animals that couldn’t hurt anything. But the twisted story line kept their eyes glued to the television and couldn’t stop watching. Narratives are used in the film; firstly we have todorov’s theory which basically changes something that should be causing and equilibrium. This works well in the film because with â€Å"Evan’s† childhood blackouts stick with him due to his family history, for example his father before him experiencing black =outs and went insane because of it. after this event, 7 years later the blackouts return but this time instead of ignoring them he goes to see his childhood sweetheart â€Å"Kayleigh Miller† who ends up committing suicide as soon as â€Å"Evan† begins changing part of the equilibrium. Changing the blackouts to bring Kayleigh back to life by stopping her father abusing her and changing the video camera moment to something different. This causes several equilibriums and continues for most of the film. This all ends after killing Kayleigh with dynamite as he visits the blackout a second time. This allows him to end the film and also the equilibrium in two possible ways. One is to return as a baby killing himself inside his mother’s womb, or secondly going back to a party that he first met Kayleigh and telling her that he never want to see or have anything to do with her ever again. This causes everybody’s life to be happier and on the downside he can choose never seeing Kayleigh again or killing himself. Until the present day when finishing college seeing Kayleigh walking along the street and begins to following. Causing the equilibrium to finish for good. The DVD case shows several layers. As the layer starts as a skull showing problems that hurts everyone in everything that he does. Then ends up as a butterfly with the problems coming to end and never hurting anybody else. Or in fact Kayleigh Antony Scott 12TJI

Methodist denominations

Methodist denominations are today represented by four major churches: the United Methodist Church, the African Methodist Episcopal Church, the African Methodist Episcopal Zion Church and the Christian Methodist Episcopal Church. The present paper describes and compares these four institutions.Historically, the Christian Methodist Episcopal Church is a denomination, composed of African Americans, who adopt and employ Methodism as their religious worship (Bucke, p.340). â€Å"The group was organized in 1870 when several black ministers, with the full support of their white counterparts in the former Methodist Episcopal Church, South, met to form an organization that would allow them to establish and maintain their own polity, that is, to ordain their own bishops and ministers without the necessity of them being officially endorsed or appointed by the white-dominated body† (Bucke, p. 342). Nowadays, the organization has its publishing house in Memphis, Tennessee.According to inte rnal documentation concerning leadership, bishops are elected as superintendents of the church and can perform their duties until the age of 74, importantly, there are no gender restriction for this position, so females are entitled to be elected.   Bishops are supposed to appoint pastors (or local clergy), protect and preserve the beliefs of the church and perform ordinations (Heitzenrater, p. 348; Bucke, p. 343). The major characteristic of this denomination is the belief in the universal redemption, under which everyone can be saved, regardless of their ‘earthy’ activities.Other prominent beliefs include: the importance of Christian perfection and spiritual development; the possibility or leaving this church (for another one, or rejecting christian beliefs completely); the priority of faith; the possibility of witnessing the Holy Spirit in this life and the importance of observing sacraments (Baptism and the Lord’s Supper) (Heitzenrater, p. 351). The church has three branches of power – legislative (the General Conference), exeutive (Episcopacy) and judicial (the Judicial Council).The African Methodist Episcopal Zion Church was also intended as a religious organization for individuals of color and was established in 1821. The word ‘Zion’ refers to the Biblical teachings and means ‘Church’ (Heitzenrater, p. 398). â€Å"The society of this new denomination called itself the â€Å"Freedom Church† at the time, because the founders decided to dedicate it to the liberation of the human spirit. Spiritual, social and economic freedom were very important to the founders† (Wigger, p. 284).The members of this church share almost the same beliefs as those who belong to the CME, but AME Zion seems to impose more obligations upon its participants, as its statute claims that individuals are basically miserable and therefore should dedicate themselves to serving God in order to receive the real blessing t he achieve personal liberty. This denomination is extremely concerned about the religious affairs in African countries and therefore its missionaries regularly visit the corresponding countries. While the CME is administered by bishop, who has the full range of entitlements, the most critical decisions in the AME Zion are taken during the general conference, but the hierarchy and bureaucracy in this denomination are also uncomplicated and actually not exceedingly formalized (Bucke, p. 401).The United Methodist Church is among the largest Protestant denominations (Wigger, p.225 ) , as it has accepted under its roof a number of minor organizations, which nowadays have very low level of autonomy and both officially and factually belong to the single church. â€Å"The United Methodist Church is organized into conferences† (Wigger, p.227).   The General Conference is the most influential organization, entitled to express the opinion of the whole church and to approve decisions a nd projects.The General Conference is gathered every four years, and each meeting results in the publication of the Book of Resolutions, or additional principles and plans to implement. Jurisdictional and Central Conferences are hierarchically lower and therefore accountable to the General Conference (Kimbrough, p. 118). The main objectives of the jurisdictional meetings (which also take place every four years) are electing bishops as well as chief administrators of the members units and planning basic activities for these executives.The Annual Conference, accordingly, is aimed at appointing minor clearly like pastors and (re-)interpreting the Book of Discipline. â€Å"Annual conferences are further divided into Districts, each served by a District Superintendent. The district superintendents are also appointed annually from the ordained elders of the Annual Conference by the bishop.District superintendents are not superior in ordination to other elders; upon completion of their se rvice a superintendent they   routinely return to serving local congregations† (Kimbrough, p. 119). Importantly, this denomination allows women to serve as bishops and in general observes the same Christian principles as the two above described organizations, based upon the individual salvation and outreach work with the disadvantaged.   On the other hand, the UM is a bureaucratic and formalized organization, which has strict leadership structure and therefore might be at risk of the monopolization of the power by the single participant (Kimbrough, p. 124).As for the clergy of the organization, they are divided into three ‘positions’: bishops, elders and deacons, the last group of religious workers are responsible for technical performance of liturgies and also might be employed as educators, musicians or business administrators, i.e. they can combine their participation in the UM with more secular activities.Elders have the same responsibilities, but the main difference between these two classes of the clergy is the regulation of appointments: deacons have a chance to choose the locality where they wish to serve, whereas elders are assigned directly by the Annual Conference (Kimbrough, p. 130; McEllhenney, p. 429). According to another classification, local pastors are distinguished from the other three categories.Local pastors, conversely to bishops, deacons and elders, are not required to have master’s degree in theology (divinity) or related sciences. In order to avoid the misuse of entitlements in local churches, the conferences can annually make new appointments for all local congregations, but the same deacons, elders and pastors serve at the certain local organization for years.The African Methodist Episcopal Church was established in the 1850s and has almost the same organization as the UM, so the primary decision-making body is the General Conference, during which bishops are elected. â€Å"The bishops are the chief Off icers of the Connectional Organization. They are elected for life by a majority vote of the General conference which meets ever four years. Bishops are bound by the laws of the church to retire following their 75th birthday† (Heitzenrater, p. 473).The Council of Bishops is also called the Executive Branch of the denomination, as it is responsible for applying the new statutes, adopted during the General Conference. The Board of Incorporators is the supervisory body that conducts analysis and partial control of the Council’s activities and determines whether they match to the overall religious course, established by the organization. The General Board is the administrative body, responsible for the distribution of material resources and financial affairs of the denomination, so it approves the decisions made by the Council of Bishops and provides the resources needed for applying new rules or principles, building new churches or colleges (this denomination has sixteen hi gher education institutions).The Judicial Council is charged with resolving the conflicts within the denomination and also dealing with corresponding appellations (McEllhenney, p. 463). The major mission of the AME is supporting the nurturing physical and spiritual development of its congregations as well as the whole society in general. More specific objectives are as follows: â€Å" 1) preaching the gospel; 2) feeding the hungry; 3) clothing the naked; 4) housing the homeless; 5) cheering the fallen; 6) providing jobs for the jobless; 7) administering of the needs of those in prisons, hospitals and nursing homes; 8) encouraging thrift and economic advancement† (McEllhenney, p. 658).In conclusion, it is necessary to summarize the similarities and differences between the denominations. First of all, they have approximately similar beliefs and missions, which necessarily include brotherly aid for those in need and education for the youth: all churches have their own education institutions, which provide holistic training in various disciplines beyond theology. Furthermore, all these churches are concerned about the current political and social affairs and although they do not directly engage into non-religious movements, they always state and publicize their attitudes towards such issues as terrorism, the U.S. trade deficiency and ethnic segregation, moreover, actively help ethnic minorities.As for a parishioner, all churches are comparatively ‘democratic’ in their beliefs and do not place too strict constraints upon the individual’s lifestyle (fasts etc) and skillfully use the principles of social work like the empowerment and reinforcement of community capacities. On the other hand, the united Methodist church and the African Methodist Church have more complicated hierarchical structure and therefore appear more ‘formal’ organizations and therefore have more prescriptions for deacons, elders and pastors, serving for loc al congregations.All denominations avoid gender discrimination and view females as equal to males in terms of their entitlements. Finally, the CME and the AME Zion appear more sensitive to the recent changes in social life or recent crises, as their responses to the adversities bred by hurricane Katrina were the most rapid,   even though these organizations are much smaller that the others.Works cited1)Bucke, E.
