Essays on Buffer

Korea was bisected at the end of the Second World War, as a response to the differing political climates which each half of the peninsula espoused – North Korea preferred the communism of the Soviet Union, while South Korea was more in line with the policies and politics espoused by the west, the U.S. in particular. During the early fifties, hostilities between the two halves of the country reached breaking point, and the Korean War broke out, with the People’s Democratic Republic of Korea attempting to reunify the country by conquering South Korea, and the American army attempting to ...

Q1. A 200mm diameter pipeline divides into two smaller pipelines, one being 100mm in diameter and the other being 150mm in diameter. If the velocity in the 100mm pipe is 0.3m/s and that in the 150mm is 0.6m/s, calculate the flowrate in litres/s and the velocity in m/s in the 200mm pipe. [ 13 l/s, 0.413m/s] Solution: Flow Rate = (pi/4)(0.1)2(0.3) + (pi/4)(0.15)2(0.6) = 0.01296 cubicmeters/sec = 12.96 l/sec. (ans.). Velocity = (Flow Rate)/(Area) = [0.01296]/[(pi/4)(0.1)2] = 0.4125 m/s. Q2. If the specific volume of water is 0.001251 m3 /kg. calculate:

Introduction

The major proposed solutions towards controlling project risks are based upon a two-fold outlook framework i.e. the project’s uncertainty and the frequency of changes effective in the project’s lifecycle. Presumably, if a project has a relatively truncated level of uncertainty, a head-on, race-to-the-finish approach is most suitable, as only very little is expected to go wrong in the entirety of the project. The fast approach technique is preferred because it maximizes on the project’s present value, and consequently realizing the remunerations from the project as soon as is possible. Comparatively, established that a project runs an ...

Overview: Overview: Antigen-antibody reactions are commonly used in immunological assays. In a traditional agglutination assay, the end product is a visible antibody-antigen complex that settles as visible particulate matter in the solution. In other cases, the reaction is invisible and wants the use of a specific enzyme or isotopic probes that can amplify the signal created by the antigen-antibody reaction, so that they can be detected with the naked eye or an ELISA/RIA reader1. Hemagglutination is a visible antigen -antibody assay in which soluble antibodies react with antigen on the surface of (red blood cell) RBC to form a ...

Psychology: Baddeley’s Working Memory

Introduction – Baddeley’s Working Memory Short term memory is an important aspect in human lives as it influences behavior and outcomes in daily lives in more ways than one – of which the role played in development of working memory is an important factor. Even though short term memory is considered to have significant differences from working memory, they are considered to be related by eminent psychologists. The most common factor behind this perspective is that both short term memory and working memory are involved in the storage of information temporarily in an individual. Working memory can be best described ...

Creative cognition involves the analysis and comprehension of the processes and mental representations within creative thought. Creativity refers to the ability to create original, useful and appropriate work. Creative thinking, however, never follows the same pattern. Psychologists have presented data to the effect that discoveries, inventions, and original ideas originate from insight, others, however, are of the view that discoveries originate from the cumulative application of expertise or prior knowledge (Smith et al., 1997). The two schools of thought have led to a contention among psychologists on whether creativity involves prior knowledge and expertise or simply, insight. The dominant ...

Introduction

Polymerase Chain Reaction (PCR) is a very influential technique that helps in amplifying the specific segments of DNA. This biochemical procedure is performed in-vitro that is quite different from cloning. This technique is a fusion of synthesis protocol of distinct repeated segments of DNA and thermostable DNA polymerase application that has given scientists a very potent analytical, immunological and molecular technique used prevalently in clinical laboratory science (Garibyan & Avashia, 2013). PCR is based on three primary steps that include denaturation of the template into single strands, annealing ...

Introduction

The ability to concurrently develop a product and its supply chain is a major competence in manufacturing industries. When the tow activities get undertaken efficiently at the same time, massive returns are bound to get derived. Proper design ensures that goods produced have the highest quality possible. High quality guarantees customer satisfaction and improves the brand name and legacy. Suitable supply chains, on the other hand, ensure that goods and services reach the customers on time. They also provide that the cost of supply is greatly diminished and saves the company revenue. However, in the auto-manufacturing industry, this ability ...

SORTING ALGORITHMS

INTRODUCTION Two sorting algorithms are studied in this paper: bubble sort and quicksort. Bubble sort is a comparison-type algorithm. It compares the elements of the array two at a time. It starts comparing from left to right of the array elements. The element with the greater value is placed on the right, and then compared to the next element. This is done until the largest element is placed at the end of the array. At this point, the largest sorted element is considered sorted, while the rest of the elements are unsorted. The algorithm is repeated for the remaining ...

Conflicts in the African continent are notorious with their complexity. There are host of reasons for that. These include the complicated history of Africa, especially of the last several centuries when existing divergences were accentuated by the presence of colonists who imposed new circumstances and conditions. These also include many natural reasons stemming from climate conditions and geopolitical situation of Africa. These include as well the ethnical and tribal divergences that turned out to be the major fueling factor in the conflict that set it ablaze for almost fifteen years. There is one thing I am going to make ...

I. Introduction Advances in recombinant DNA technology and bioinformatics-based data analysis have driven the explosion of structural biology in the last two decades (Kelly, Jess, and Price 119). This has resulted to the identification of at least 2000 proteins annually and a growing need in performing structural studies in these new proteins. The current trend involves the concern of analyzing protein structures close to its natural conditions (and other conditions) and of measuring their rates of structural changes, an essential factor in their biological functions. The technique of circular dichroism (CD) has gained an increasing popularity in addressing these ...

Introduction

Acids and bases are chemicals with a wide range of applications both industrially and on small-scale basis. According to Arrhenius, an acid is a substance that liberates H+ when placed in water (Slabaugh & Spencer, 167). On the other hand, a base is a substance that liberates OH- when placed in water (Slabaugh & Spencer, 167). To illustrate, pure water dissociates partially to produce hydrogen ions and hydroxide ions as shown in the equation below: H2Ol H+aq+ OH-aq In the above equation, water dissociates to produce H+ and OH-. If an acidic substance is placed in water, it reacts with ...

Abstract Paternity test is usually performed to individuals, where their DNA are compared to other people DNA to see if these people or person, is parent to the individual or are related. The method involves use of restriction enzymes to cut DNA from samples, which are then analyzed using gel electrophoresis. Gel electrophoresis will separate the DNA according to size and charge. They will be viewed on gel as bands. Normally, the DNA patterns are usually unique for an individual. Therefore, if there is a match is patterns from the analyzed samples, then there exists close relationship between two ...

The current business ecosystem is increasingly defined by uncertainty. Given how dynamic and innovative makeup of current workforce, rapidly changing market conditions (particularly for cross-border companies) and, not least, growing adoption of innovative enterprise resource planning (ERP) platforms and applications has made uncertainty a normal component in current business ecosystems. This uncertainty is made more intense by a changing concept of work by which workers are no longer "fixed" to one specific, physical location but are becoming increasingly mobile performing routine and non-routine functions in virtual environments enabled by computer-based platforms and infrastructures. The case for planning under uncertainty ...

Size-Exclusion Chromatography in Purification of Proteins Literature Review

Size-exclusion chromatography is a biochemistry process used for a number of uses in the laboratory. The process is used to purify protein, for desalting, buffer exchange, or for separating a group whereby the sample has two major groups. Size-exclusion chromatography is a simple method for separating molecules which have different molecular seizes under mild conditions. It makes use of the size of molecules in solutions to determine the method and means of separation. For instance, spinColumns have short media packaging so that the samples in the solution are separated using the size. Size-exclusion chromatography, also referred as Gel Filtration, ...

Q. 1. Explain how gel filtration chromatography (size exclusion chromatography) separates molecules on the basis of their mass/size.

A. In gel filtration, porous beads are packed into a column. The pores are of different size. The column is then packed with a buffer solution. This buffer solution is present inside the beads as well as around it. When molecules of different size pass through the columns, the smaller molecules pass through the pores and take a longer path. The larger molecules, however, travel around the beads. Thus, larger molecules travel faster than the ...

Introduction

Initially there were beliefs that, MMPs are jointly able to degenerate all constituents making up the extracellular matrix (ECM) together with basement membrane that confines their operations to tissue reconstruction as well as the preservation. Nonetheless, the contemporary studies also signify that MMP-1 is responsible for controlling the production or else the activation of the chemokines. At this point, it is critical to understand that MMP-1 is among other MMPs. Similarly, the knowledge holds it that MMP- 1 cleaves a peptide bond beforehand a residue comprising of a hydrophobic adjacent chain, for instance Met and Leu. The other sideways chains cleaved ...
