Dark Energy Essay Example | Topics and Well Written Essays - 500 words

Dark Energy - Essay Example Ideally, it is the volume of space that consists intrinsic basic energy. It is equivalent to vacuum energy in reality since it is the energy density of unfilled vacuum. The general relativity theory denotes that the energy will have an effect on gravity (Wang 76). Cosmological constant is characterized by negative pressure that is equivalent to its energy density. As such, it causes acceleration on the expansion of the universe. Quintessence refers to the hypothetical form of energy that can be attractive or repulsive. It is a scalar field that has its equation defined by the ratio of pressure to its density. Attraction or repulsion of this energy is dependent on the kinetic to potential energy ratio (Morrey Bsc & Morrey 112). Quintessence serves to solve part of the problems accruing from cosmological constant. Unlike cosmological constant, quintessence is a dynamic equation that varies with time. In addition, it differs from cosmological constant from the fact that it forecasts a slower increase in rate of expansion of the universe. The third alternative idea stems from the string theory. String theory stipulates that an atom’s elementary particles are dimensional swinging lines (Amendola and Tsujikawa 64). It is a quantum theory of gravity. The theory comprises configurations that define all observed basic forces and matter, but have zero cosmological constant. The methods employed in determine the above ideas are geometry of space, exploding stars and the late- time integrated Sachs- Wolfe effect (Amendola andTsujikawa 340). Exploding stars is ideally the supernovae. Type la supernovae offer a standard candle for the measurement of the distance to galaxies that are much far away. It combines the information with redshift; a measure for the speed at which galaxy recedes. Conclusively, astronomers have inference that there is a factor that is contributing to the increased velocity of the recession of galaxies. The geometry

How to Research Knowledge Management Topics

How to Research Knowledge Management TopicsThis article is a simple explanation on how to successfully research on your own knowledge management topics and decide on your best choice for a topic. Understanding and applying the right strategy is what it all boils down to.Let's start with a very important knowledge management topic that all students should know. That topic is how to write an essay. This is actually a long paper and if you want to get through it faster, you may want to use an assignment or outline. While writing the paper you need to keep some points in mind:Effective knowledge management topic requires you to fully comprehend what you are writing about. You need to understand its importance and what it relates to.For example, let's say you choose to write about 'answering' questions and have no idea about what you are answering. Just write down the question in its entirety and let your imagination guide you. Is it really important?Make sure you take note of the standar d format of writing, its meaning and type of answer that will help you in choosing the best answer. If there are no specific standards, you should choose the best one that is most appropriate.Another important knowledge management topic that most students don't think of is about topics that they really don't have enough information about. The way to research is to conduct research and then ask someone who can provide more information.Research paper is the most crucial part of your studies, because it takes about 20% of your time. Always remember that in order to succeed in your degree or diploma, you need to get knowledge on topics.

Molecular Biology of Sickle Cell Anemia Term Paper

Molecular Biology of Sickle Cell Anemia - Term Paper Example This reduces the oxygen carrying capacity of the blood and causes the jamming of blood vessels. One of the characteristic symptoms of sickle cell anemia is pain. Sickle cell anemia is found mainly in people belonging to malaria endemic regions for e.g. Africa. A definitive cure for this debilitating illness is yet to be found and so the treatment given to the patients is still largely symptomatic and supportive. (Taylor et al. 1997 pp.859) (Abnormal phospholipid molecular species of erythrocytes in sickle cell anemia, Connor et al. 1997) Hemoglobin: Structure The structure of the hemoglobin molecule was deciphered by scientists, Kendrew and Perutz using X-ray crystallography in 1959. Hemoglobin is an oxygen-carrying chromoprotein. It is found in red blood cells of vertebrates. 1 red blood cell contains approximately 600 million hemoglobin molecules. It consists of 4 Heme molecules which are attached to 4 polypeptide or globin chains. Heme is a cyclic tetrapyrrole i.e. it consists of 4 molecules of pyrrole. It imparts a red color due to the methyl, vinyl and proprionate groups attached to it. Each heme group also contains one ferrous ion (prosthetic group)present in the porphyrin ring which is present in the center of the heme. The 4 globin chains that make up a hemoglobin molecule are known as ?and ? chains. The two ?chains each contain 141 amino acids, while the two ?chains contain 146 amino acids. These chains are derived mainly from chromosome 16 and 11. Hemoglobin is a globular protein and the 4 protein chains are held together in what is known as a quaternary structure. The hydrophobic parts of the chains point inwards towards the molecule, whereas the hydrophilic parts point outwards. This makes the molecule soluble in water. (Taylor et al. 1997 pp103, 859) (Interactive-Biology 2012) (The Molecular Biology of Sickle Cell Anemia, 2003)(Hemoglobin: Molecular modeling, 2011) Hemoglobin: Function The hemoglobin molecule is responsible for the transport of oxy gen from the lungs to the cells of the body. Each oxygen molecule is attached to the ferrous ion in each heme group. Thus, one hemoglobin molecule is capable of carrying 8 oxygen atoms at a time. It also carries the carbon dioxide molecules back to the lungs for excretion. Carbon dioxide is carried in three forms: in solution, as carbamino-hemoglobin and as bicarbonate ions.(Taylor et al. 1997 pp.479, 481) The hemoglobin molecule shows cooperative binding kinetics, i.e. when one oxygen molecules has been attached, the binding of the rest of the oxygen molecules becomes easier. The oxygen-dissociation curve is sigmoid. It shows that at low partial pressures of oxygen, the hemoglobin molecule readily gives up oxygen, which is then used up by the tissues. Increased concentrations of carbon dioxide also cause the release of oxygen from the molecule. Under these conditions the curve shifts to the right. This is known as the Bohr Effect. (Taylor et al. 1997 pp.479-480) Hemoglobin: Synthes is Hemoglobin synthesis starts to occur in the proerythroblast stage of the RBC cycle. The molecule is produced by mitochondria and ribosomes in a series of reactions. Heme is synthesized in the mitochondria. Glycine &succinyl-CoA condense to form  ?-aminolevulinic acid  (ALA). This reaction occurs in the presence of ALA-synthase. ALA exits the
