Spectroscopy Introduction

Spectroscopy Introduction Spectroscopy is a technique that uses the interaction of energy with a sample to perform an analysis. What Is a Spectrum? The data that is obtained from spectroscopy is called a spectrum. A spectrum is a plot of the intensity of energy detected versus the wavelength (or mass or momentum or frequency, etc.) of the energy. What Information Is Obtained? A spectrum can be used to obtain information about atomic and molecular energy levels, molecular geometries, chemical bonds, interactions of molecules, and related processes. Often, spectra are used to identify the components of a sample (qualitative analysis). Spectra may also be used to measure the amount of material in a sample (quantitative analysis). What Instruments Are Needed? Several instruments are used to perform spectroscopic analysis. In simplest terms, spectroscopy requires an energy source (commonly a laser, but this could be an ion source or radiation source) and a device for measuring the change in the energy source after it has interacted with the sample (often a spectrophotometer or interferometer). What Are Some Types of Spectroscopy? There are as many different types of spectroscopy as there are energy sources! Here are some examples: Astronomical Spectroscopy Energy from celestial objects is used to analyze their chemical composition, density, pressure, temperature, magnetic fields, velocity, and other characteristics. There are many energy types (spectroscopies) that may be used in astronomical spectroscopy. Atomic Absorption Spectroscopy Energy absorbed by the sample is used to assess its characteristics. Sometimes absorbed energy causes light to be released from the sample, which may be measured by a technique such as fluorescence spectroscopy. Attenuated Total Reflectance Spectroscopy This is the study of substances in thin films or on surfaces. The sample is penetrated by an energy beam one or more times, and the reflected energy is analyzed. Attenuated total reflectance spectroscopy and the related technique called frustrated multiple internal reflection spectroscopy are used to analyze coatings and opaque liquids. Electron Paramagnetic Spectroscopy This is a microwave technique based on splitting electronic energy fields in a magnetic field. It is used to determine structures of samples containing unpaired electrons. Electron Spectroscopy There are several types of electron spectroscopy, all associated with measuring changes in electronic energy levels. Fourier Transform Spectroscopy This is a family of spectroscopic techniques in which the sample is irradiated by all relevant wavelengths simultaneously for a short period of time. The absorption spectrum is obtained by applying mathematical analysis to the resulting energy pattern. Gamma-ray Spectroscopy Gamma radiation is the energy source in this type of spectroscopy, which includes activation analysis and Mossbauer spectroscopy. Infrared Spectroscopy The infrared absorption spectrum of a substance is sometimes called its molecular fingerprint. Although frequently used to identify materials, infrared spectroscopy also may be used to quantify the number of absorbing molecules. Laser Spectroscopy Absorption spectroscopy, fluorescence spectroscopy, Raman spectroscopy, and surface-enhanced Raman spectroscopy commonly use laser light as an energy source. Laser spectroscopies provide information about the interaction of coherent light with matter. Laser spectroscopy generally has high resolution and sensitivity. Mass Spectrometry A mass spectrometer source produces ions. Information about a sample may be obtained by analyzing the dispersion of ions when they interact with the sample, generally using the mass-to-charge ratio. Multiplex or Frequency-Modulated Spectroscopy In this type of spectroscopy, each optical wavelength that is recorded is encoded with an audio frequency containing the original wavelength information. A wavelength analyzer can then reconstruct the original spectrum. Raman Spectroscopy Raman scattering of light by molecules may be used to provide information on a samples chemical composition and molecular structure. X-ray Spectroscopy This technique involves excitation of inner electrons of atoms, which may be seen as x-ray absorption. An x-ray fluorescence emission spectrum may be produced when an electron falls from a higher energy state into the vacancy created by the absorbed energy.

buy custom Effects of Using Instructional Technology in Schools essay In recent times, issues regarding education in the American federal states have attracted considerable debate in policy agenda (Kulik, 2003). This has followed the realization by the national government that the states have been insufficiently preparing students, sometimes right from elementary schools, with vulnerable/marginalized ones bearing the greatest brunt. Kulik (2003) notes that the concerns of the long term socio-economic as well as political implications that miss-ups portend have driven these debates and measures that games play in learning are being emphasized. According to him, the use of games mediated with technology, such as video games, are particularly becoming crucial component in education in American schools and other countries in relation to performance improvement. Despite these realities, some schools dont have the capacity to exploit or possess, yet it is verifiable that teachers employing games in learning have positive outcomes, particularly in Science sub jects and Mathematics (Kulik, 2003). The use of Integrated Learning Systems in (ILSs) Mathematics by Pre-school teachers is one area worth examining. Kulik (2003) observes that studies have shown that scores in Mathematics and Science subjects are often higher in with pupils taught by ILS. More interestingly, for studies that focused exclusively on mathematics, the performance is often much higher when ILS was exclusively designed to measure performance in mathematics, but lower when instructions were divided to deal with reading and mathematics alike. Further, computer games tend to be simulative. Kulik affirms that whenever these games are used, they give pupils the theoretical understanding and highly simplified strategies to relate mathematics and sciences to the real world. In a way, these prepare the students/pupils for future learning endeavors as they further their education. Regardless of studies showing that the scale is lower, Kulik believes that simulation methods using computer mediated games as well as oth er games remain helpful in preparing and equipping students with practical skills (Kulik, 2003). In sum, using games particularly those bordering on technology brings good results in education. In any case, the creation of fruitful citizens, who are not only better prepared for further education and later meaningful employment, should be the focus of educational stakeholders if responding to the needs of the universal marketplace is something to prioritize.

Anzaldua Feminist Theory Assignment Example

Anzaldua Feminist Theory The paper "Anzaldua Feminist Theory" is a wonderful example of an assignment on gender and sexuality studies. Gloria Anzaldua is known as a scholar the cultural theory of Chicana queer theory and the feminist theory. The poetry marked a very significant feminist intervention in the studies that bring some different perspectives and experiences and is usually considered as vital in the feminism development in the third world. In the year 2002 Anzaldua co-edited with another anthology which was known as the bridge called home. In the writings made by her, she makes a combination of the autobiography and all the historical narratives between all the available languages (Haraway, 2018). Therefore, due to this her whole writings is seen as an act of transformation and questioning the genre's categories. After that, she later moves into breaking down the main subject of duality since it is usually a start of so many struggles that could at the end bring a lot of hopes by ending all the rape cases. She also argues that the lands of boarders are usually not presented physically but has more cultures at the end of each. This is where a lot of people of different origins or races are occupying the same space or area. She also goes ahead and develops some concepts that help in transforming all the binary constructions such as those of planta, borderlands and new tribalism (Mulinari, 2018). The major aim of this is bridging the gap that divides the boarders line and also binary thinking. She also goes ahead and elaborates the approach by giving a statement that all the categories usually gives an attempt to imprison, contain and also limit from growth. Due to this, the categories will be disrupted and other new ones will be created. The new ones created will be for very few years. The conc epts created poses a lot of effort in the transition and they are usually not fixed. Anzaldua views the writing act as that of being transformative and liberal. This is mainly through writing and thinking in some ways that show that knowledge systems that can be transformed at the end. The perspective of women oppression according to Hill Collins Hill Collins of the year 1997 usually argues that due to the intersecting position of race, class, and gender the black women as a whole usually possess some very unique characteristics of the world vision. When compared with the everyday experiences of all the black women, it is usually marked by an understanding of the intersectional of the oppression and the struggle of legacy against women oppression (Hirschmann, 2018). In this particular article, the quantitative analysis of the data that is from the national survey of all the black women is compared. There are some questions raised whether the black women as a whole group moves towards the standpoint that is described by Hill Collins. To what extent the Anzalduas theory is important to the women portrayal in the mainstream media and the women oppression in the present world. The theories of Anzaldua is the mentality in the borderlands' and they are usually taken from the real theory and later put into the actual action. This usually serves as a mirror that portrays the hybridity depiction and gives more emphasis on the significant stories of the true culture journey as a process of woman-centred (Espn, 2018). The actual book that is mostly dealt with is the Texas book of the Mexican border. In fact, most of the stories are usually inspired by growing or simply childhood in America. This is due to the fact that more standards are on the Mexican than American. However, in the areas where there are a lot of inhabitants are of Mexican origin. She also becomes punished for the heritage by the minority numerical. Afterwards, she later remembers how they used to be punished for simply being Mexican. This is oppression and can lead to a lot of defects. The main use of a borderland which is physical is usually very helpful and acts as a symbol for the psychological, emotional and the political forum of Mestiza. In fact, in many cases, the borderlands are usually present physically where two or more cultures are seen to be at the edge of the other. Therefore, it is very important to always note that the first preface of the very first edition of the borderlands will give an explanation of how and where the different people of different races usually occupies the same area or territory. Where in the cases of the lower and upper classes there is space of the individuals that usually shrinks with intimacy. The borderlands which are seen physically characterize the whole ceremony at large. The different parts of the whole narrative are usually set in separate locations from the perspective of the theatre. The reader is instilled some sense by Silko of the various differences between the different backgrounds of individuals in a polarized existence. This is the existence that refers to the different physical places terms that come as a representation of some categories and also the ethnic groups (Espn, 2018). For instance, most of the comrades are usually subjected to whiteness during the period of war and this reinforced to make a reference to some places. In most cases, it was usually the laughing and drinking with the platoon with the women who were born in Cleveland. Silko also uses some various physical borderlands that usually make an illustration of the conflicting nature of the polarity. The separated people in this category usually do not live in the areas of isolation but in most cases are usually forced to make some interactions in one way or the other that portrays the surface differences. Similarly to Anzaldua, she also uses the borderlands which are physical in symbolizing the whole scenario. This is where Tayo lives in the environment in the southwestern that is the same as the one portrayed by Anzaldua. The main battle is not only between the Indians and the white man but in most cases, the groups usually face some division amongst themselves as is illustrated by Silko. Also, in other cases, Tayo assisted as he had promised. This is seen after finding some wires sagging and also some trucks along the fences. This was seen as women oppression. CONCLUSION In conclusion, it is clearly seen that the feminist US history has been evolving from a womanhood notion that is on the basis of the normative model of the middle-class people. Therefore, a lot of women usually experiences some kind of recognition that in most cases women are usually diverse and views themselves to be very different. It is also stated that the major problem of feminism is how the whole condition is usually confused to that one group condition of all women. When making some assumptions of the middle-class experiences all the white women were a representation of the lives of women and some false unity amongst the women presupposed. By taking into account the forms which are overlapping and multiple of the oppression of women especially on the basis of colour there must be a negotiation in the third world. This reveals the diversity and complexity of the lives of women. For instance, in the US, the women of colour usually pass through a lot of struggle on defining who t hey are to the white men. The same occurs in the third world women who in most cases find themselves fighting against the experiences omission and the assumptions of the first world. Away from the notion of women the feminist theory in the US usually engages differently by focusing on the specific positioning of women in relation to the other categories changing. By addressing the oppression of women complexity of the whole multitude most of the communities are usually on the basis of race, gender, and class. The links of the political nature chosen to make a mark between the whole scenario struggles. The political alliances are usually formed by the race or sex of a person. Although this is mainly on the context or basis of the usual struggles contexts against the structure exploitation. In the present world, the feminism mainstream is usually engaged by diversity recognition and the formation of the coalitions of the cross-cultural injustices.

Tourist guide system Essay Example | Topics and Well Written Essays - 500 words

Tourist guide system - Essay Example base stations such as chain of cell base stations, units that are designed to be hand-held that are based on Off-the-Shelf Fujitsu Team Pad Units and visitor’s information as reflected in the PC back at the office. These stations are PC’s that are standard that have a link to the internet as well as a WaveLAN Card. Thus, these base stations enable broadcasting of data and information that is within the vicinity and transmissions of position information from the local cells. Additionally, a GPS can be fitted if more accurate information is needed. In order to be able to retrieve data from the device, one need to press the ‘info’ button which then displays all the information about the visitor’s current position. The version in this project is an advanced version of the former that displayed a number of position choices on the tourist’s location. This is because unlike the project guide device, the former version of the guide device did not have the search engine (Andrew, 2009). However, using the new version, the visitors’ position can be identified using a Guide Tag Insert Position. This label is useful in identifying a visitor’s location in a dynamic way. For example, a tourist can identify their location by just asking a question on his or her location. This approach has got many advantages over the earlier approach. Using this guide a visitor is able to make bookings online, able to identify his location, make text messages and also able to navigate to various places. The earlier a pproach did not have the ability to identify the location of the visitor and also was not portable like the latest model. According to Martin 1994, push based strategy of information delivery is found in the communication between the tourist and the guide. The delivery of information in this case can be non-interactive or can be interactive. For example if the delivery of information is done through a radio or television then interactions between the buyer and the

Research Methodologies in Communication Paper Example | Topics and Well Written Essays - 1500 words

Methodologies in Communication - Research Paper Example In the field of communication, quantitative research seeks to establish communication as a behavioral science. The researchers using this method use the scientific models to show the effect of different aspects of communication. Some of the research areas include areas such as, the effect of medical marijuana advertisements on the American population, and the effect of violence games on children. The qualitative research methods produce reliable and quantifiable data that can be generalized to represent a greater population. The weakness that this method has is that it removes the research from the human behavior perspective (Weinreich1996). This makes the information to lose touch with reality by ignoring the factors that were not included in the research. Qualitative research methods are important in exploring a singular occurrence of importance. The methods used include interpretation of data and observation through personal interviews and ethnography. These research methods seek to explain a research question or problem from the perspective of the population that the research is conducted (Mack, Song et al. 2011). When it comes to matters dealing with opinions, behavior, values as well as social contexts of a community, qualitative research methods are effective to do the research. Using this method is advantageous in that it describes complex situations of how people deal with, or perceive a particular research issue. In examining the occurrence, they make reference to the full context of the phenomenon.
