They are categorized into portioning, hierarchical and graph-based techniques. The most widely used of the three algorithms are the graph-based technique, and the hierarchical technique. However, the partitioning techniques are used in other disciplines. it is less used in gene sequence clustering and as such, there is no substantial theory of whether the partitioning methods are efficient. This study analyzes four clustering mining algorithms using four large protein sequence data sets. The analysis highlights the weakness and shortcomings of the four and proposes a new algorithm based on the shortcomings of the four algorithms. Introduction Today, protein sequences are more than one million (Sasson et al., 2002) and as such, there is need in bioinformatics for identifying meaningful patterns for the purposes of understanding their functions. For a long time, protein and gene sequences have been analyzed, compared and grouped using alignment methods. According to Cai et al. (2000), alignment methods are algorithms constructed to arrange, RNA, DNA, and protein sequences to detect similarities that may be as a result of evolutionary, functional or structural sequence relationships. Mount (2002) asserts that comparing and clustering sequences is done using pair-wise alignment method, which are of two types, global and local. Consequently, local alignment algorithm proposed by Waterman and Smith (Bolten et al., 2001) is utilized in identifying amino acid patterns that have been conserved in protein sequences. The global alignment algorithm proposed by Wunsh and Needleman (Bolten et al., 2001) is used to try and align many characters of the entire sequence. It is clear from the above that. the pair-wise alignment method is expensive when it comes to comparing and clustering a large protein data set. This is because there are very many comparisons performed during computation, since every single protein in a data set is compared to all the proteins in the data set (Bolten et al., 2001). This brings into question the efficiency of the pair-wise alignment methods in comparing and clustering of large protein data sets. The pair-wise alignment method, both local and global, do not put into consideration the size of the data set, especially too large data sets that may overwhelm the computer memory. Han &amp. Kamber (2000) argues that, unsupervised learning is aimed at identifying from a data set, a sensible partition or a natural pattern with the help of a distance function. Biology and life science fields have extensively exploited clustering techniques in sequence analysis to classify similar sequences into either protein or gen families (Galperin &amp. Koonin, 2001). Currently, protein sequences can be classified in similar patterns using various, readily available sequencing and clustering methods. As had earlier been mentioned, these methods can be grouped as graph-based, partitioning and hierarchical methods. These methods, especially graph-based and hierarchical methods, have been used consecutively or together to complement each other as argued by Sasson et al. (2002), Sperisen &amp. Pagni (2005), Essoussi &amp. Fayech (2007) and Enright &amp. Ouzounis (2000). In the field of protein comparison and sequence clustering, there are very few instances in which partitioning techniques have been used.

Even though she feels that it is quite safe being in a lifeboat as it would be anywhere else, the story progresses to a rather unpleasant conclusion, wherein at a certain point, Annette stands at a juncture where she is supposed to decide over participating in an act involving cannibalism. Despite this being one of the worst forms of evil, her decision is in the onset of a mundane reality. Annette’s character clearly projects the tendency among women by which they look to escape through fantasy along the paths of stereotypes that they have grown and socialized

Lastly shifting to bio fuels seems as an easy way of reducing carbon emission

The world yearns to reduce carbon emission especially after Kyoto protocol and Copen Hagan reports were released. Environmentalists and human rights activists are putting pressure on countries that are producing high carbon energy on the environment to reduce or pay heavy fines with the aim of reducing carbon emission for sustainable development. Our energy wedge is based on conservation of green resources and use of renewable sources of energy as a means of conservation. Nuclear wedges comes in second as a means of preventing of cutting carbon emission by half by the year 2055. Nuclear energy is capable of producing a lot of energy but is not widely used since it possesses high risks to the environment. The above two wedges are good ways of producing energy without production of carbon. (Wardlaw, 2009). A growth rate of 5.3% annually is projected in production of low carbon environmental goods and services (Nesta, 2009). There has also been tremendous increase in green jobs from 1370 billion dollars from now to 2740 billion dollars by 2020, which is projected as a growth rate of 5.5% annually (Office, 2009). Due to the involvement of new technology while shifting from fossil energy sources to renewable sources of energy, it is expected that job creation will rise from 24% annually to 42% by 2020 (UNEP, 2007).

The demand for low carbon activities is exceptionally high. The next wedge of conservation is efficiently producing electricity. Use of coal as a source of energy leads to production of about a fifth of worlds carbon. Conserving forests ensures that trees absorb carbon emitted and use it as a source of food production. Soil is also another form in which carbon products can be stored. This can be supported by planting cover crops and preventing soil erosion. Use of biofuels is believed to be cost

The similarities of these two types of writings is that they both are effective when it comes to communicating something clear enough to the audience it is meant for (Ellis, et al, 45). The main similarity that they also tend to share is that they all require the competence in grammar for proper written communication. Due to official setting that both academic work and business work require, it is then necessary to deduce that there is requirement for the written communication to be competent in order to avoid issues that may arise regarding misinformation.

There are also differences that can be pointed out as far as these two types of writings are concerned. The first is that students write with the purpose of learning whereby in business, writers has the intention to get work done. In scholarly material, the writing is done to demonstrate to which level learning has been accomplished whereby in business setting the writing is to prompt some sort of action to be undertaken by the relevant bodies concerned. The instructor prompts scholarly work whereas business writing is for the complex groups or people that correlate with the company in the likeness of the stakeholders. The content of business writing is based on the thesis of the work provided by the student instructor whereas the in business scenario only what is intended for the audience is included in writing and everything else is added in the
