Fascinating Argumentative Essay Sample on Higher Education

Argumentative Essay Sample on Higher Education by Tom Nixon Introduction The main purpose of the paper is to study and analyze the article Higher Education Is Now Ground Zero for Disruption by Tom Nixon, the contributor of the Forbes magazine that is devoted to the problem of higher education cost and quality within the contemporary American education system (Nixon, 2014). The author claims that the contemporary higher education in the United Stets is of the poor quality, high costs, and does not guarantee the future success of the graduated specialists. At the same time, he underlines the rapid growth of the popularity of on-line education that can be the effective solution to the enlarging problem that exists within the society. On the other hand, despite the facts that are presented to the readers within the article, it is essential to mention that there is a series of arguments opposing to that of the author. Although Nixon makes a good point about the weak sides of the higher education within the country, he ignores the fact that this system is suppo rted by the years of successful work and the generations of graduated professionals, while the on-line education has not proved its efficiency and high quality.

Student Athletes And Physical Education - 1604 Words

It is often discussed whether or not it is fair that student athletes have to take physical education in order to graduate. Envision a student who does very well in school and would like to take advanced placement or running start classes in order to better prepare themselves for college. This student, however, cannot take these classes because he or she has to take physical education, a gradation requirement, and does not have the schedule flexibility to fit both classes in. Almost every school in the United States requires students to take physical education in order to graduate. Since physical education is a requirement, students are not able to take important advanced placement or running start classes.

Nature and Scope of Earth Science free essay sample

Some also use their knowledge about Earth processes such as volcanoes, earthquakes and hurricanes to plan communities that will not expose people to these angerous events. Earth science is also known as the Geosciences, the Geosciences or Earth sciences. It is arguably a special case in planetary science, the Earth being the only life-bearing planet. There are both reductionist and holistic approaches to Earth sciences. The formal discipline of Earth science may include the study of the atmosphere, oceans and biosphere as well as the solid earth. Typically, Earth scientists will use tools from physics, chemistry, biology and mathematics to build a quantitative understanding of how the earth system works and how it evolved to its urrent state. Like all other scientists, Earth scientists apply the scientific method: Problem statement, Review literature, Formulate hypothesis after observation of and gathering data about natural phenomena and then test these hypotheses. Finally, there is the need for one to publish and explain the research in the scientific community. We will write a custom essay sample on Nature and Scope of Earth Science or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It must however be pointed out that Earth science is inter-disciplined†it cuts across all sciences and study fields. Science in the broadest sense refers to any systematic methodology which attempts to collect accurate information about the hared reality and to model this in a way which can be used to make reliable, concrete and quantitative predictions about events in line with hypotheses proven by experiment. In a more restricted sense, science refers to a system of acquiring knowledge based on the scientific method, as well as to the organized body of knowledge gained through such research. The scope of science, therefore, is knowledge through reason†and the scope of Earth science is knowledge of the Earth systems through the study of combined science. Knowledge is, therefore, borrowed rom other disciplines such as Geology, which is the study of the earth surface(rocks) and interior; Astronomy, the study of the universe that the Erath is a part of; Meteorology, the study of the weather and Earths atmosphere and Oceanography, the study of the Earths oceans(the four Earth sciences). Geology is the primary Earth science. Literarily, it means the study of the Earth. Geology deals with the composition of earth materials, earth structures and earth processes. It is also time. Geologists search for fuels and minerals, study natural hazards and work to protect earths environment. Meteorology is the study of the atmosphere and how processes in the atmosphere determine earths weather and climate. Since everyone is concerned about the weather, it can be considered very practical. For instance, how climate changes over time in response to the actions of people is a topic of urgent worldwide concern. Oceanography is the study of the Earths oceans†their composition, movement, organisms and processes. The oceans cover a greater part of the planet. The oceans have a major influence on the weather and changes in the oceans can drive or moderate climate change. Oceanographers work to develop the ocean as a resource and protect it from negative human impact. Astronomy is the study of the universe. Studying space beyond dearth is important since the moon derives the oceans tidal system, asteroids impacts have repeatedly devastated Earths inhabitants and energy from the sun drives our weather and climate. When talking about the nature and scope of Earth Science, it is also necessary to talk about its importance. Today, we live in a time when the Earth and its inhabitants face many challenges. Our climate is changing and that change is being caused by human activity. Earth scientists recognize this problem and will play a key role in efforts to resolve it. Again, we are also challenged to develop new sources of energy that will have minimal negative impact on climate; locate new sources of metals and other mineral resources as known sources are depleted. In a nutshell, the scope of Earth science is knowledge of the earth systems through the study of combined science which also looks at data collection and research woks and the subject being inter- disciplined.

Applications of fluorescent protein-based biosensors for the elucidation of protein function within cells Essays

Applications of fluorescent protein-based biosensors for the elucidation of protein function within cells Essays Applications of fluorescent protein-based biosensors for the elucidation of protein function within cells Essay Applications of fluorescent protein-based biosensors for the elucidation of protein function within cells Essay Biosensors are used for sensing of an analyte ( e.g. a little molecule, a protein, or an enzymatic activity ) and its interaction with a molecular acknowledgment component, MRE ( e.g. a protein sphere ) . It consists of 3 parts ; the sensitive biological component, the transducer or sensor component ( which transforms the signal resulting from the interaction into another signal that can be more easy measured and quantified ) , and signal processors ( show consequences ) . Biorecognition processes require biosensors to hold the ability to transduce an event into an discernible alteration e.g. coloring material or fluorescence hue i.e. an effectual transducer component. A alteration frequently attach toing an event is an change of the geometry of the MRE ( distance alteration between the MRE and its analyte protein-protein interaction, or a conformational alteration of the MRE allosteric proteins ) . In recent old ages, biochemists adapted the term biosensor to mention to genetically encoded designed proteins that are self-sufficing sensing systems for a figure of marks. The chief difference between conventional biosensors and genetically encoded biosensors is the nature of the transducer. Conventionally, a transducer is a man-made and modified surface that is electrochemically or optically sensitive to the action of the biomolecule. In contrast, the pick of transducer for a genetically encoded biosensor is constrained to being genetically encoded ( 1 ) . Aequorea green fluorescent protein ( FP ) and its discrepancies are a critical constituent of genetically encoded biosensors. The scope of FP-based biosensors which include different designs can be used by research workers to supervise alterations in the geometry of an MRE through the assorted features of the FPs e.g. transition of the fluorescence chromaticity or strength of an intrinsically fluorescent protein. The usage of genetically encoded FP-based biosensors offers several advantages compared to other techniques ( such as dye-based investigations ) . They are comparatively easy to build utilizing standard molecular biological science techniques and can be used to analyze protein localization of function and kineticss within life cells. The latter occurs through the non-invasive debut of these biosensors into cells ( they are produced utilizing cellular machinery ) where they can obtain information of specific biochemical and biorecognition procedures from any one of a broad scope of cellular compartments without interfering with the interaction ( 2 ) . All genetically encoded FP-based biosensors can be assembled into the undermentioned 5 groups depending on their construction: * Group 1 intramolecular FRET-based biosensors * Group 2 intermolecular FRET-based biosensors * Group 3 BiFC-based biosensors * Group 4 individual FP-based biosensors with an exogenic MRE * Group 5 individual FP-based biosensors with an endogenous MRE Group 1 biosensors are based on intramolecular Forster Resonance Energy Transfer ( FRET ) . FRET is the distance- and orientation-dependent nonradiative transportation of internal energy from a higher-energy giver fluorophore to a lower-energy acceptor fluorophore through dipole-dipole yoke. FRET-based biosensors have all of their constituents on a individual polypeptide concatenation ( two FPs flanking an MRE ) and the analyte brings about a alteration in the construction or conformation of the MRE unit ( see Fig 1 ) . Modulating the distance or comparative orientations between the fluorophores affects the FRET efficiency, which is revealed by the acceptor ( IA ) /donor ( ID ) emanation ratio i.e. an addition in IA at the disbursal of ID. FRET occurs about outright and is reversible, therefore supplying better declaration than the BiFC method ( discussed subsequently ) ( 3 ) . Application of this biosensor design includes sensing of proteolytic activities. An MRE consisting of a polypeptide that is a substrate for the peptidase under probe is used to observe proteolytic activity. Tsai MT et Al ( 4 ) late carried out a survey to supervise intracellular human enterovirus ( HEV ) peptidase activity by utilizing a HEV 3C peptidase FRET-based biosensor. They found that this system was a agency for rapid sensing, quantification and drug susceptibleness proving for HEVs. FRET-based biosensors can besides be used to observe post-translational alteration ( PTM ) enzymes activities. An MRE with the ability to observe PTM enzyme activity ( catalyses the covalent alteration of a substrate ) is composed of a specific substrate and a binding sphere. The MRE so undergoes geometry alterations in response to PTM activity. This attack was late used to observe ERK ( kinase enzyme ) activity. EKAR, a genetically encoded FRET-based detector of ERK activity was designed and te sted. EKAR selectively and reversibly reported ERK activity after EGF stimulation in HEK293 cells, leting for the analysis of ERK signalling in life cells ( 5 ) . A 3rd application of this design is to observe MRE conformational alterations triggered by the presence of its analyte. Some proteins e.g. bacterial periplasmic binding proteins ( 6 ) undergo such a alteration. Consequently, they have been used to do FRET based biosensors for analytes such as glucose, Ca2+ and Zn2+ . Group 2 includes biosensors based on intermolecular FRET. The two FPs are in two different polypeptide ironss ( the MRE is fused to one FP and the analyte protein is fused to another ) and are brought closer together by a protein-protein interaction ( see Fig 2 ) . This design has been used to analyze the oligomerisation province of different members of the G-protein-coupled-receptor ( GPCR ) superfamily. It has besides been used to analyze mGluR1 activation. Marcaggi P et Al ( 7 ) employed the FRET phenomenon to analyze the activation dynamicss of mGluR1. The writers show that the alterations in FRET correlative with activation of the receptor. Care must be taken when construing intermolecular FRET consequences, since FRET may perchance happen between two proteins that show no interactions straight. There may besides be fluctuation in the look degree of the two halves of the biosensor. This is of peculiar concern when ratiometric measurings are taken. Group 3 biosensors, bimolecular fluorescence complementation ( BiFC ) , enable direct visual image of protein interactions in life cells. The BiFC attack is based on the reconstitution of a fluorescent composite when two proteins ( MRE and analyte ) , fused to non-fluorescent fragments of a fluorescent protein, interact with each other. The interaction between the merger proteins facilitates the association between the fragments of the fluorescent protein ( see Fig 3 ) . This attack enables visual image of a assortment of protein-protein interactions in the normal cellular environment. BiFC composites have been visualized in all major subcellular compartments of mammalian cells, including lysosomes, the plasma membrane, lamellipodia, Golgi, the endoplasmic Reticulum, chondriosome, viral atoms, and lipid droplets. It has provided particular penetration into the ordinance of complex localization of function including atomic translocation ( 8 ) . It has besides been used in a survey of the grippe A polymerase composite to find the interaction between its 3 fractional monetary units ( PA, PB1 and PB2 ) required for the written text and reproduction of the viral genome. It revealed a antecedently unknown PA-PB2 interaction and provided a model for farther probe of the biological relevancy of the PA-PB2 interaction in the polymerase activity and viral reproduction of grippe A virus ( 9 ) . A motley BiFC check may besides be used for coincident imagination of more than one event in unrecorded cells. This check is based on the formation of fluorescent composites with diffe rent spectra through the association of fragments belonging to different FPs, making Chimeras with a assortment of fluorescent chromaticities ( see Fig 4 ) . This technique was used in a survey to look into the oligomerization province of adenosine A ( 2A ) and dopamine D2 GPCRs found to be ligand-dependent, and besides how they were affected by the presence of certain drugs ( 10 ) . A restriction of the BiFC attack is that there is a hold ( dependent on the sensitiveness of the sensing method ) between the clip when the merger proteins interact with each other and the clip when the complex becomes fluorescent. This is due to the slow rate of the chemical reactions required to bring forth the fluorophore. Therefore, an advantage of FRET over BiFC analysis is that real-time sensing of complex formation and dissociation is possible. Group 4 biosensors use an exogenic MRE inserted into a individual FP at certain locations. Information about the birecognition event from the MRE is carried to the chromophore altering its spectral belongingss ( see Fig 5 ) . A biosensor with this design was used in a recent survey by Berg J et Al ( 11 ) . The detector was constructed by uniting cmpVenus ( a circularly permuted discrepancy of green fluorescent protein ) with a bacterial regulative protein ; GlnK1 ( used an ATP specific MRE ) . Binding of ATP caused conformational alterations in GlnK1 protein which ratiometrically changed the excitement profile of cmpVenus. Initially, the purpose was to find the ATP concentration. However, as ADP binds to the same site ( bring forthing a smaller alteration in fluorescence than ATP ) , competition between the two substrates made the detector more suited for ratiometric measuring of ATP: ADP concentration ratio by excitation. , in unrecorded cells. This is a all right illustration of tuning and optimizing biosensors. The same design has been used for Ca2+ , Zn2+ and cGMP sensing in other surveies. Group 5 biosensors besides use a individual FP but with an endogenous MRE. An illustration of this design is a redox-sensitive GFP ( roGFP ) . By permutation of two surface-exposed residues on the Aequorea Victoria green fluorescent protein with cysteines in appropriate places to organize disulfide bonds, redox-sensitive GFPs ( roGFPs ) were created, which allowed for ratiometric measuring of the cell oxidation-reduction position ( 12 ) . This theoretical account has late been improved through merger of roGFP to human glutaredoxin-1 ( Glx1 ) , which catalyses rapid equilibration between roGFP and glutathione, bettering the response rate of roGFP ( 13 ) . Most FP discrepancies show pH-dependent alteration in their spectral belongingss, which consequences in a alteration in their fluorescence strength. This makes measurings hard to graduate. To get the better of this restriction, the pH-dependent alterations in EGFP ( an engineered avGFP discrepancy ) fluorescence life-time have late been imaged, instead than strength, as the former does non depend on fluorophore concentration ( 14 ) . It must be noted that some designs do non suit the 5 chief classs. Esposito et Al ( 15 ) displayed an interesting illustration of FRET-based pH biosensor that is composed of a pH-insensitive giver fluorophore and a pH-sensitive acceptor fluorophore. Unlike the conventional FRET-based biosensors that depend on the alterations in comparative distance and/or orientation of the fluorophores, this biosensor depends on the spectral alterations of the acceptor fluorophore that accompany pH alterations which in bend change the overlap built-in impacting FRET. Decision As research continues, life scientists will look to engineer a complete set of biosensors that are specifically tuned to the conditions of the event under probe. In add-on to building new biosensors, it is of import to go on bettering the specificity of the current theoretical accounts. This may even happen through incidental findings such as that found in the survey by Berg J et Al, which looked ab initio at ATP concentration but subsequently found that the biosensor was a better index of the ATP: ADP concentration ratio ( see above ) . Another avenue which can be explored is the monitoring of more than one cellular event through a combination of different types of biosensors. An interesting illustration of this is a survey by Ai H W et Al ( 16 ) which looks at observing caspase-3 activity in the cytol and nucleus utilizing two FRET braces at the same time. This survey shows how the usage of this brace preserved the temporal declaration of the caspase-3 activity in the cytol and in the karyon. Despite the unknown and yet to be explored, there has been immense advancement in the development of genetically encoded biosensors. Through such devices, researches now have an increased ability to image specific biochemical and biorecognition procedures with the saving of subcellular information. Mentions 1. Campbell, R. E.
