Ice - Lab Report ExampleWe kept the bottles in hot water until we heard the ice crack and it slid from the bottle. When ice slid from separately bottle we immediately measured the height and diameter of to each one ice art object. Then we placed each piece of ice on a telegraph grate and say which piece of ice had come from which bottle. We placed the wire grate with pieces of ice on it away from the wind and waited for the ice to melt and noted the time with the stop watch. Meanwhile we calculated the surface area of the cylindrical ice pieces using the formula 2rh + 2r2 where r is the radius and h is the height of each piece of ice. We have used the formula of a cylinder to find the surface area of all pieces of ice because all pieces of ice frozen in different medicinal bottles had assumed almost the same cylindrical shape but they all had different diameters. We then repeated the whole experiment triad times using the same medicine bottles and noted the time taken for ice pieces to melt in each trial as followsOur experiment be that the shape of a piece of ice affects its melting time. As can be seen in the table the greater the surface area of a piece of ice the smaller its melting time.

Therefore, it is un congenial to ask details more or less age, income, salary, or even personal details such as weight, among others. It is definitely uncomfortable for one to see or to experience people from other cultures behaving in ways perceived as unacceptable in one. For the particular example of public display of affection, people from Western culture deem it normal and acceptable to shake hands, embracing each other, hugging, as a sign of greeting or bidding goodbyes. The behavior, regarded as unacceptable in Arab culture, and even in rough Asian culture, should be revealed and known in the Western culture so that people would understand how to properly behave in day to day interactions without pique other people from diverse cultural orientations. As indicated in Echo Depiction, Arabs quickly gain a negative impression if one (even a westerner) behaves besid es open with a person of the opposite sex.Arabs could interpret that sort of behavior by their standards and consider the person to have low moral standards (par. 5).

Beneficiaries of U.S. Welf ar Programs - Essay Example3). Therefore, the U.S. Welfare programs aim to stabilize the well-being and full-blooded balance of people of the U.S. The U.S Welfare programs focus mainly on food needs of children, economics, and education. Among of these welfare programs are the School Milk Program of 1973, the Basic educational Opportunity Grants, and the American Recovery and Reinvestment Act by Obama. The School Milk Program of 1973 aims to provide free milk in schools especially in needy children. Approximately 111,000 half pints of milk were served daily and 13.5 million cartons were sold daily at reduced prices. Almost 3% of the total nonfarm milk consumption was allocated in school milk program. In 1973, the milk, children received from this program is separate from the milk included in school lunches and breakfasts but the new school lunch action requires application of income rules for free and subsidized lunches to school milk. It is a prerequisit e that schools participate in both programs, school milk program and school lunch act, in order to qualify the children for free school lunch and servings of extra milk (Anderson, 1980, p. 217). Education welfare programs such as Basic Educational Opportunity Grants are intended for needy college students and for students in vocational and technical schools.

Politics course work - Essay ExampleThe main principles of the console government are as follows. The monarch (Queen Elizabeth II) has the force play to appoint or dismiss any ministers to the government, although this is usually done on the advice of the Prime attend (Heyward, 2008, p20), meaning that the monarch has very little political influence. When these changes are made, this is referred to as a reshuffle, something which generally happens on a yearly basis. The footlocker are generally chosen from the current Prime Ministers confess political fellowship, with the butt cabinet those who hold a corresponding role to those in the cabinet being formed of the official opposition (the largest non-Governmental party, currently the beat back Party) (Heyward, 2008, p17). The versatile titles and duties held by the members of the cabinet (and the corresponding shadow cabinet) change depending on the demands of the UK population and the views of the currently elected premie r. The currently appointed cabinet government take a leak weekly meetings to discuss potential and actual policy changes. These weekly meetings have ensured that the Institute of Government see the cabinet government as having a rock-bottom capacity as a decision-making body (Blick & Jones, 2010, p97) due to their infrequency and short length. Despite this, however, it is the cabinet that makes policy decisions and thus hold all responsibility for these decisions. The various ministers and secretaries within the cabinet must exhibit public support for the decisions made for the government and all policy choices must be made collectively. In practise, many another(prenominal) decisions can be and are delegated to the sub-committees of the cabinet, such as education, who carry out all research, present findings and seriously influence the final choice of the governmental cabinet (Heyward, 2008, p14). As previously mentioned, the cabinet is generally chosen from members of the curre nt Governmental party, such as the Labour Party under Tony Blair (Kavanagh et al., 2006, pp32-34). The current Governmental party is chosen using the first-past-the-post system the party with the most seats gains power, despite how many votes they may have in total. This system requires that the winning party holds at least 326 seats in Parliament to hold a majority, or else a hung parliament will occur. In the event of a hung parliament, it is necessary to pass water a coalition government of two or more political parties so that the total number of seats held by these parties totals at least 326. In the case of the 2010 elections, the Conservative Party won 306 seats and formed a coalition with the Liberal Democrats, who won 57 seats, giving a total of 363 seats. The shadow cabinet is thus formed from members of the Labour Party, who hold a total number of 258 seats (BBC News, 2010). The creation of this coalition government means that the current cabinet is formed from members of both the Conservatives and the Lib Dems. There are 18 cabinet ministers or secretaries from the Conservative Party and 5 from the Liberal Democrats (BBC News, 2010). This ratio must be well-kept throughout Camerons premiership if a Liberal Democrat leaves cabinet, another must be appointed in their place (Daily Telegraph, 2010). The traditional role of Prime Minister has also been affected David Cameron currently holds the office, but Nick

WEEK 8 journal 6500 - Essay Examplen for errors to occur during practice, that failure to report these errors could lead a habit that may end up causing serious problems in the future especially when patient sentry duty is concerned. When the nursing students were checking blood sugars, the nurse on the hall wanted them to dry their finger that had been wiped with alcohol by fanning it finger using their hand. According to patient safety, act in preventing that would be a wrong technique. The finger should air-dry. The nursing students did it the way the nurse wanted them to even though it was wrong so as not to upset the nurse on the hall.Nursing students need to understand that patient safety comes first, and it is okay to report an error or raise concern if they chance upon an error being committed by a senior nurse or physician. Having an error-reporting system is one important strategy for improving the healthcare system. isolated from offering safety through reporting and tracing underlying causes, it further offers information about potential future errors and problems (Kim, Kim, Kim, & Kim, 2007). According to Wolf & Hughes, (2008) ethical principles of almsgiving (doing well) and non-maleficence (preventing harm) are violated when errors are not reported or disclosed. The situation I observed at the practicum site mirrors what research has found to be key reasons that lead to medication administration errors, which is a real world problem. A study carried out to identify barriers to the reporting of medication errors found administrative barriers and fear were found to be the top two reasons for not reporting medication administration errors among nursing students (Koohestani & Nayereh, 2010).Kim, M.-S., Kim, J.

Codon bias in E. Coli Essay Example for Free

Codon bias in E. Coli EssayThe nature of the constituent codon varies among organisms. Codon preferences have been considered on the perspectives of transformational efficiency and fidelity and the selective and non selective biases operating during DNA transcription replication and repair processes. Variations in tRNA on codon bias of extremely expressed ingredients during rapid growth phase of E. coli exist. Codon selectivity is influenced by codon/anticodon interaction strength, place specific codon biases, time of replication, codon context, or evolutional age.Codon preferences among component classes in E. coli be grouped consort to the following comparisons correlation of codon biases with level of agent expression, organisation of genome according to genome partitions based on coat, codons use for genes characterized by function and cellular localization of gene products, gene size, comparisons that divide all genes by similarity of codon customs duty or amino acid usage or similarity of a reduced set of amino acid or codons and characterization of alien genes. The Codon Adaptation Index (CIA) is a qualitative measure for assessing codon bias.Ribosomal protein (RP) genes and membrane genes be genes that are utmostly expressed during riotous growth and CIA and codon bias (CB) values are inversely correlated with respect to RP genes. Most ribosomal proteins are highly expressed during the E. coli exponential growth phase during which to the highest degree genes facilitating translation are highly expressed. Codon preferences differ among highly expressed genes relative to the average gene for certain amino acid types, especially disparities for alanine, aspartine, histidine, isoleucine, phenealanine, threonine and valine.There is a high correlation between optimal codons and level of gene expression. In relation to E. coli genes, codon biases in general increase with increasing protein molecular weight abundance. Codon usage difference s generally decrease with respect to protein molecular abundance when compared to RP. Negative correlation in the degree of protein molar abundance relative to tRN genes or other sub classes of the translation functional category is non evident.The molar abundance and codon usage differences unequivocally correlate negatively with the RP gene family and positively with the average E. coli gene respectively. The E. coli genome is homogeneous with relatively weak codon biases among the genes distributed over the genome. Codon bias does not depend on timing in the replication cycle except near the ter region. The deviation in codon usage from RP and tRN genes is most emphatic at ter region. Relative codon usage bias among 5 middle and 3 parts of genes in E.coli show that the middle and the last troika of genes are much similar in codon usage than either is to the initial third of the gene.There also exists a difference in the frequencies of 3 G+C near the oriC than near the ter reg ion. Different bacterial genomes display variation in their overall G and C content, attributed to varying mutational mechanisms and processes. For eukaryotic genomes site 3 G+C frequencies decrease with increasing gene length. Alien genes are characterized in terms of extreme codon bias relative to average E.coli genes and high relative to RPs.These genes are of unknown function and are either GC rich or AT rich. Extremes in codon bias are for identifying pathogenicity islands and developing gene classes reflecting difference expression levels in untypical events. When the genome is divided into contigs, gene classes and dicodon bias is most pronounced between the gene classes of the region about the oriC versus the ter region. Dicodon bias increases with gene size and compared to the average gene dicodon biases are constant throughout the genome.When genes are divided into thirds, the dicodon biases of the 5 third, middle third . 3 third parts of genes are similar though level of bias is about twice that of straight codon bias. Codon and dicodon bias correlations for E. coli genes were evaluated for level of expression, contrast along genes, size of contigs around genome and gene size classes. Explanations for codon bias have involved combinations of selection and mutational pressures.The RPs and amminoacyl tRNA synthetases are highly expressed gene classes during exponential growth of E.coli. Codon biases for RP genes are much more extreme than for tRN genes. The greater the abundance a gene product, the more its codon usage resembles hat of RPs, but this is not the case for comparisons to tRN genes or protein genes essential to translational activities. For gene classes RP and tRN, the source of codon bias differs significantly. RP are among the most deviant from the average E. coli gene. It is suggested that codon usage and tRNA abundance are correlated for highly expressed genes to match substratum levels with cellular demands.Hence RP genes which are sm all single domain proteins show high codon usage correlation with overall E. coli codon usage and tRNA do not show this bias although they are highly expressed. The middle and final 3? end of genes entail the same levels of codon biases. The rare codon hypothesis for domains and secondary structures argues that the use of repetitious rare codons might reduce translational rate and induce translation pauses allowing protein domains and suitable secondary structures to fold into native structural conformation.There are differences in prokaryotic and eukaryotic translational mechanisms. These differences may be important in translation initiation or early stages of translation. Highly biased slowly translated codon pairs are more closely correlated with levels of expression than with protein length. Understanding basis of codon usage is of interest with respect to fundamental evolutionary questions, gene prediction, gene classification and propose of optimal expression vectors. Codon usage programs are essential for gene finding and analysis of prokaryotic and eukaryotic genomes.
