Aging, Its Ethical and Cultural Issues Research Paper

Thesis Statement Culture is a critical characteristic for the elderly because it results in ethical issues that threaten and affect the general quality of life negatively among the aged. Quality healthcare for the aged is considered as a strain on resources in other quarters. It is also accused of creating overpopulation. Old people from minority communities do not receive quality healthcare services similar to those given to the majority of communities. The elderly are exempted from the right to life because they are thought to be less important. Healthcare givers stigmatize the elderly, thereby failing to provide services to the elderly because suffering in this group is acceptable as a norm. Introduction Several ethical issues that relate to aging in society arise from the threat and differences in culture. The elderly have been castigated by their frail condition and the fact that their contribution to society is less compared to other energetic members of society. Culture is a critical characteristic among the elderly because it results in ethical issues that threaten and negatively affect the general quality of life among the aged. This paper analyses three important ethical issues, including the right to life, cultural biases, and stigmatization and stereotyping that the old suffer by their condition and age. Emerging Claims Right to life The right to life is a common concept adopted by almost all societies and communities around life. However, this concept has been applied selectively concerning the old. Right to life is only looked at when referring to the embryo and not when referring to the improvement of life quality for the old. The old are looked at as people who have already enjoyed life, thus they no longer require special efforts and resources to better their conditions. Those in support of this view argue that life therapies only succeed in creating overpopulation in the society, which in turn results in underdevelopment. Immortality therapies have continued to receive strong opposition, with those holding divergent views looking at these treatments as infringements to the rights of younger and upcoming generations or denying them the ability to have children (Haigh

Developing Sensor Technology

essay writing service free Developing Sensor Technology. Abstract The need for sensor devices has been growing to develop new applications in several technological fields. The current state-of-the-art of this sensor technology used in modern electronic nose designs to operate in a different manner. The chamber of the E-Nose sensor is to be upgraded mainly for reducing the nuisance alarms and to improve reliability to detect smoke which is caused by fire and non-fire particles. This paper gives a brief state of the art of different fire and non-fire particles that emits smoke and various chemical gas sensors used to detect smoke and a fire detection algorithm. Keywords- Sensors; Smoke; Electronic-Noses; Fire Detection Algorithm fire particles; non-fire particles Introduction The conception of an electronic nose could appear sort on an up-to-date technology. Scientists initial developed a synthetic nose within the 1930’s that used sensors to measure levels of ultra-violet light found in mercury. Currently these devices are employed in numerous technological fields for various applications. Presently these devices used as trendy fireplace detection frameworks for the simultaneous estimations of carbon monoxide gas (CO), carbon dioxide (CO2), and smoke. The concentration of the rates of CO and CO2 in smoke offers a path to cut back the frequency of nuisance alarms so as to extend the reliability of smoke detectors. The sensors that square measures incorporated during this fireplace sighting system at the side of fire detection algorithmic rule detect smoke that is caused by fire or non-fire particles, and alarmed accordingly. Previous fire detection systems used sensors for measuring temperature, smoke, and combustion products which include oxygen (O2), carbon monoxide (CO), carbon dioxide (CO2), water vapor (H2O), hydrogen cyanide (HCN), acetylene (C2H2), and nitric oxide (NO) but they does not give any reliable results. Some used Gas Chromatography – Mass Spectrometry (GC-MS) along with Fourier Transform Infrared (FTIR) Spectroscopy analyzed smoke [1]. Advances in fire detection systems are being sought to decrease the detection time and the frequency of unnecessary alarms. Most of the research works done with the Multi-Sensor Detectors for accomplishing these goals because there may have some trouble in using smoke detectors with a single sensor to discriminate the smoke produced from fire and non-fire sources. The 95% frequency of unnecessary alarms reported by smoke detectors during the 1980’s in the U.S. is due to that limitation. Section 1 briefly introduces the Fire Detection System incorporated in an Electronic-Nose and different Gas Sensors that detects smoke in Section 2. Later, section 3 gives a brief description about the Fire and Non-Fire Particles and how the sensory system is designed in an E-Nose for preventing Fire accidents in section 4. Finally, we concluded in Section 5. Chemical Gas Sensors The environment needs to be monitored [2] time to time as many accidents took place lack of it. So in order to control the Industrial Process, Chemical Sensing Technologies has been emerging out to mainly emphasize on Control of combustion processes (oxygen) Flammable gases in order to protect against Fire Explosion. Toxic gases for environmental monitoring. Solid Electrolyte Sensor SE sensor [3] [4] is based on the principle of electrochemical gas detection, which is used to detect chemicals or gases that can be oxidized or reduced in chemical reactions. It mainly contains three electrodes: A sensing or working electrode which reacts when gas is available by either oxidizing or reducing the target gas. A counter electrode which provides a comparing converse response to that occurring at the sensing electrode so as to provide a net current stream. A reference electrode that stays unaffected by the chemical reactions occurring on the sensing and counter electrodes and provides a stable potential against which measurements are frequently created. Figure 1. Solid Electrolyte Sensor SEC sensors (Figure 1) used in millions of vehicles to monitor the exhausted gases and minimize the toxic emissions. Thermal-Chemical Sensors Thermal-chemical sensors [2] works on principle that there will be a change in temperature (∆T) when heat energy is released or absorbed (∆Eh). The pellistor is the most common thermal-chemical sensor (other thermal sensors are based on either on thermistors or on thermopiles). They are used for monitoring of combustible gases. Figure 2.Thermal-Chemical Sensors Gravimetric Chemical Sensors They are also known as piezoelectric sensors [5]. They are of two types used for gas sensing – Surface Acoustic Wave (SAW) device and the Quartz Crystal Micro Balance (QCM) as in Figure 4. Figure 3. SAW Device Figure 4. Quartz Crystal Balance SAW device produces a surface wave that travels along the surface of the sensor while the QCM produces a wave that travels through the bulk of the sensor as shown in Figure 3. Both work on the principle that a change in the mass of piezoelectric sensor coating due to gas absorption results in a change in the resonant frequency of exposure to a vapor. Conducting Polymer Sensor: Conducting polymers [2] are plastics and they change their resistance while they adsorb or desorb specific chemicals (Figure 5). The adsorption of these chemicals mainly emphasized on the polarity (charge) and their molecular structure (shape and size). Figure 5. Conducting Polymer Sensor Due to their high sensitivity, low price and rapid response time at room temperatures, Conducting Polymer Sensor best suits for chemical sensing. IR Spectroscopy Sensors: The Spectroscopic Sensors [2] determine the concentration of several gases at a time and they work on the principle that all the gases interfere and adsorb infrared spectrum at specific wavelengths due to their natural molecular vibration. Some systems with narrow band interference filters or laser light sources for a specific gas (like CO2) are termed as monochromatic systems. Figure 6. IR Spectroscopy Sensors In the above Figure 6, some concentration of CO2 present in the sample gas is absorbed by the infrared detector at a wavelength of 4.3 μm while an infrared light periodically emitted from the light source. These sensors are most suitable for CO2 gas and shows low cross-sensitivity with different gasses and are moderate at the reaction, fairly good at accuracy and linearity but are cumbersome and costly. Optical Fiber Sensors The optical fiber utilized as a locality of those sensors [6] is coated with fluorescent dye. On association with the vapor, the Polarity variations within the fluorescent dye will changes the dye’s optical properties such as wavelength shift in fluorescence, intensity and spectrum changes. These optical as in Figure 7 changes are used as the retaliation mechanism for gas. Figure 7. Optical Fiber Sensor Optical gas sensors are mostly used to detect concentrations of ammonia (NH3). They have very fast response times, short of what 10 micro sec for sampling and analysis and are compact; lightweight can be multiplexed on a single fiber network, immune to electromagnetic interference (EMI) and can operate in high radiation areas. MOSFET Sensors: The metal oxide semiconductor field-effect transistor (MOSFET) sensors [4, 7] based on a change of electrostatic potential. They comprise of three layers, they are catalytic metal also called the gate (palladium), a silicon oxide insulator (platinum) and a silicon semiconductor (iridium or rhodium) as in Figure 8. When polar compounds interact with this metal gate, the current flowing through the sensor is modified. Figure 8. MOSFET Sensor [7] As no hydrogen atoms are released, molecules such as ammonia or carbon monoxide cannot be detected with a thick metal layer. But it can be possible to detect them when the metal gate is thinned. These MOSFET sensors or MOS sensors are very robust and have a relatively low sensitivity. E-Nose as Fire Detection System An electric or artificial nose can sense different types of chemicals and even distinguish particles not only for identifying individuals, but also used for the detection of fire. They work on the principle that smoke is made up of different chemical compounds. These devices consist of dozens of sensors that sense different types of chemical compounds found in the air. Some of the chemicals that cause smoke leads to flames are discussed below. Smoke It is a collection of solid and liquid particulates in air and emits gases when a material undergoes combustion or pyrolysis [8]. This is a commonly an unwanted by-product of fires (including candles, stoves, fire ramp and oil lamps), but may also be used for fumigation i.e., pest control. Smoke signals is communication for long distances like smoke signals to transmit signals, news or to indicate the people to gather in a place, offensive and defensive capabilities in the military (smoke-screen), cooking, or smoking like marijuana, tobacco and etc.). Heptane: It is a non-polar solvent and minor component of gasoline [9] with chemical formula H3C (CH2)5CH3 or C7H16. This is a colorless liquid and very hazardous chemical that appears which sense like petrolic odor. The structure of Heptane is shown in Figure 9. Figure 9. Heptane Structure It is commercially available as mixed isomers for use in paints and coatings and mainly applied in pharmaceutical manufacturing laboratories and for researchDeveloping Sensor Technology

Interview Summary/Synthesis

Interview Summary/Synthesis. Help me study for my English class. I’m stuck and don’t understand.

For this assignment, you should be interviewing a person who has expertise about a topic you are interested in. Please note that you should be conducting an actual interview; you should not be summarizing an interview conducted by someone else.
Part #1: Choose a Research Topic and an Interviewee
You do not need to submit this portion in writing, but you do need to accomplish this in preparation for your research assignment.
In preparation for your research proposal letter in the next topic, you will need to choose a topic for your proposal. This research proposal letter will be directed to an audience who can create change (Congressperson, business administrator, or other similar audience). In the proposal, you need to suggest a change or a solution to a current problem. Examples of strong proposal topics would be things like funding ideas for an animal shelter, starting a recycling program in a community, suggesting a better plan for public transport, or another idea that interests you. You will be proposing solutions for these issues. Choose a topic that you are passionate about and for which you will be able to develop at least one solution. While this information should be enough for you to choose a topic, please consult the assignment sheet within Topic 7 if you have more questions about this assignment.
Once you choose a topic, it’s time to choose a credible expert to interview on that subject. In other words, you should avoid choosing an interviewee who is a close friend or family member unless that person truly is an expert in the field. This credible expert should have 10+ years of experience in his or her discipline. Choose an interviewee who not only could offer some specific details about the problem but one who may also be able to offer suggestions of a plausible solution. Use the information contained in the lesson presentation to secure and conduct a successful interview.
Part #2: Summarize and Synthesize Your Interview
When you summarize and synthesize, you take the smaller pieces (the sections of the interview) and develop them into one cohesive piece. Doing this exercise will help you prepare for the research proposal letter, where you will need to incorporate at least a few ideas from the interview.
To successfully summarize and synthesize, you might find it helpful to follow this sequence for your essay:
1) Provide Background Information:In your introductory paragraph, introduce your audience to your interviewee. What is his/her name? What is his/her experience? if relevant, where is the interviewee employed?
2) Summarize the Interview:While you want to avoid the all-too-predictable question and answer format, you should provide information about what you learned from the interview. Take a look at your original questions, group them into categories, and use those categories to build your body paragraph(s). Also, you may note the interviewee’s reactions in your summary as well. Was the interviewee nervous about answering a question? Did he/she seem knowledgeable in the subject matter? Make this summary work for you by including whatever details and responses you feel are important and will help you when you write the research proposal.
3) Synthesize the Interview:In the conclusion, synthesize the interview. To synthesize just means that you should consider all of the information you gathered from this interview and draw conclusions. What did you learn from the interview? How did the interviewee and/or the interview help you gain a deeper understanding of your topic? Other findings?
No source citations are required for this assignment, but please review the rubric to get a better idea of how you will be assessed.
