Indoor Air Quality (IAQ) and Health

Indoor Air Quality (IAQ) and Health Of all the things that people take for granted, air would probably take the first prize. Despite the fact that without air, the life on the Earth would be impossible, the attitude towards air has been rather careless for considerably long time, which has led to a number of problems concerning air ecology in the present-day world. Advertising We will write a custom essay sample on Indoor Air Quality (IAQ) and Health specifically for you for only $16.05 $11/page Learn More One of the issues on the agenda is the quality of indoor air, the factors that influence it and the means to improve the indoor air quality, or IAQ. Because of a range of negative factors, both human-induced and natural, the average index of indoor air quality is rapidly decreasing, which can lead to a number of health issues and, therefore, requires certain actions. Although a home accommodation is not typically used as storage of toxic waste, there are still a lot of indoor factors that ma ke the IAQ worse. Among the most common pollutants, the ones that seem the most innocent or appear to be the least noticeable often take the first place. Outlining the key pollutants will bring one a step closer to understanding how to increase the IAQ. The first pollutant to mention is animal hair. Cluttering the room, it creates perfect environment for more dust and bacteria. Dust mites, which have already been mentioned, serve as the place for bacteria growth and are also classified as pollutants. Weirdly enough, food comes in a close second, mostly because its particles also clutter the area. Another source of air pollution at home, chemicals have a rather deplorable result on the state of the IAQ. While chemicals help cleaning the place, in a paradoxical way, they are also classified as strong allergens and, therefore, harm the indoor air considerably. However, banning chemicals from use as a means to clean home accommodation is not a way out either; according to the existing evidence, the pollen in carpets and upholstery that appear as a result of insufficient cleaning is also classified as an allergen and a factor that enhances IAQ deteriorate. Likewise, tobacco, or even second-hand smoke, contributes to making the IAQ even worse, since the particles of tobacco soar in the air, cluttering the lungs of the dwellers. Damp basements, in their turn, spur the growth of mould and can be related to as rather hazardous phenomenon. Finally, such issues as CO and CO2 production, as well as radon radiation that are emitted from some of the materials that buildings are constructed from, should be mentioned. Even though the hair-rising list of threats offered above is a fraction of the harsh reality, there are still some ways to handle the problem. First of all, the ecology of the environment must be improved; once the air is polluted outside, there is no way to make it cleaner inside the house. Then, certain methods of more efficient house cleaning must be adopte d. Finally, it is necessary to enhance the awareness about the home accommodation ecology among people (Plushke 242).Advertising Looking for essay on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More Summary Unlike outdoor air quality, which is usually influenced largely by industries, large-scale air pollutants like plants and factories, and toxic waste, indoor air quality depends to a considerable extent on the attitude of the person who owns the apartment. Therefore, the awareness concerning the urban ecology and especially the ecology of home accommodations must be enhanced. Meanwhile, the environmental issues must also be considered when improving the IAQ. To be more exact, more trees, which produce oxygen, must be grown so that people could enjoy high IAQ.

Free Essays on The Storm

â€Å"The Storm† In the short story â€Å"The Storm† the major components that are emphasized are plot, character, and setting. These components work together in order to make the reader visualize life from the characters’ point of view. The author, Kate Chopin, tells the story in a unique way that helps the reader understand the main characters’ attitudes. The title of the story, â€Å"The Storm†, has a twofold meaning. An actual storm that takes place in the remote Louisiana country sets off a chain of events that contributes to the passionate storm that occurs between the two main characters. The events that make up the plot begin when bad weather forces Bobinot and his son, Bibi, to remain at the store until it passes. This leaves Bobinot’s wife, Calixta, home alone. The bad weather also forces Alcee, Calixta’s old boyfriend, to seek shelter under her gallery. As a result of the driving rain, Alcee and Calixta went inside the house. A loud burst of thunder sent startled Calixta staggering backwards into Alcee’s arms. The physical contact between the two â€Å"aroused all the old-time infatuation and desire for her flesh† (97). They gave in to temptation â€Å"that unconsciously betrayed a sensuous desire† (97). Soon afterward, the storm passes and Alcee was on his way. Bobinot and Bibi return home where Calixta was preparing supper. She â€Å"seemed to express nothing but satisfaction at their safety† (98) and pretended that everything was just fine. That night, Alcee wrote a letter to his wife, Clarisse, telling her n ot to hurry back from her vacation in Biloxi. Clarisse was glad to receive her husband’s letter, and was willing to stay where she was. The locale is set in the southern Louisiana countryside; this is shown from the dialect that is used throughout the story. The setting is a very important factor in this story.

Free Essays on The Storm Free Essays on The Storm The title, of â€Å"The Storm,† has connotations of a universal swell of energy and fervor of the natural world that is obvious during the encounter of Calixta and Alcee. Just as the storm matures from the first spark of energy, likewise, Calixta is a sexually mature woman, claiming her part in the natural world. Unfortunately, as a consequence of the times, society’s attitude is intolerant of a woman’s expression of sexuality. Furthermore, Calixta’s commitment to her marriage forces her to be oppressed from expressing the sexual being within herself. During the rage of the storm’s fury, intense with the explosion of energy flowing from the storm, the escalating passion and energy also swells between Calixta and Alcee; â€Å" they seemed to swoon together at the very borderland of life’s mystery†(492) while Calixta and Alcee break free from the constraints of their marriage vows. Giving into the storm of passion that until now, neither Calixa nor Alcee has ever experienced, they give into the sexual energy and release the passion that is presently hindered in both of them. As a result, Calixta’s â€Å" the generous abundance of her passion, without guile or trickery, was like a white flame which penetrated and found repose in depths of his ow n sensuous nature that had never been reached†(492). The final line of â€Å"The Storm† is a metaphor for the relationships between Calixta, Bobinate, Clarissa and Alcee, and is positioned to create an uncertain ending of the encounter between Calixta and Alcee: â€Å"So the storm passed and everyone was happy†(493). One may see the storm’s passage as implying a happy ending or one may see it as implying that the storm will eventually return, possibly with the intent to express the fervor and powerful energy that may eventually destroy families or lives. As the nature of recurring storms, Calixta’s new founded sexual desires will return with powerful forces of energy and chemis... Free Essays on The Storm â€Å"The Storm† In Kate Chopin’s short story â€Å"The Storm†, we are introduced to two families: Calixta, Bobinot and Bibi; Alcee and Clarisse, and are asked to take a look at a moment in their lives during a severe storm. What parallels the storm as it builds to a climax and then recedes is an intimate passion between two past loves, Calixta and Alcee, but what does this moment of intimacy really mean to them and their families? We must first take a look at each family and get an understanding of how they relate to each as a family member. The father son relationship between Bobinot and Bibi appears to be one of a strong mutual trust and love for each other. As we are learning that there is a storm â€Å"rolling with sinister intention from the west† (32), we see how with great concern their safety is for one another. Bibi places â€Å"his little hand on his father’s knee† (32) as to console him and protect him from the building storm. We also know that at home Calixta, who is busy with her homemaking â€Å"sewing furiously† (32), takes a moment to think about Bobinot and Bibi and has â€Å"no uneasiness for their safety† (32). She knows that together they are safe because of the strong bond they all share. When we take a look at Alcee and his wife Clarisse, we only get a small window into their relationship, but enough to understand their deep love for one another as well. Alcee writes to his wife, â€Å"a loving letter† (35), to where she is vacationing in Biloxi to inform her to stay longer and enjoy being with her friends and the children. Alcee realizes that â€Å"their health and pleasure were the first things to be considered† (35) and will endure his separation from them in order to bring them happiness. Clarisse was â€Å"charmed† (35) to receive the letter from her husband, maybe this is the first time in a long time Clarisse has been able to see old friends and reminisce, she enjoys â€Å"the first free breath since her marri...

The setting of this story, forces the main characters Calixta and Alce to rediscover feelings they had for each other, and reveal hidden aspects of themselves. The omniscient author emphasizes the elements of the storm that takes place in the story, because the storm itself forced the plot to take place. The events leading up to the plot of the story, had a domino effect on each other. Each event contributed to the following, which made the plot inevitable. Timing is the most important element that is responsible for the development of this story. If the events in the story did not happen with such time accuracy, then the story may not have been a story or it may not have turned out the way it did. So timing is the building block for plot and the events leading up to the plot of the story. The fact that Bobinot and Bibi, Calixta’s husband and son respectively, stayed at the store until the storm was over, was the second element that contributed to the main characters Calixta and Alce having sex. If Bobinot and Bibi were home at the time of the storm, Calixta and Alce would not have had an opportunity to have sex. She would not have gravitated towards Alce for comfort during the storm if her husband and son were at home. She would have found refuge in her husband, not Alce. Another domino to add to the trail was when the winds were so strong and Calixta had to go outside to retrieve Bobinot’s clothes off of the line. At that time Alce was passing by on his horse, he saw her, and then stopped. If Alce did not see Calixta, he probably would not have stopped. And when he stopped and decided to seek shelter on Calixta’s porch, the winds were so bad, that he had to go into the house. â€Å"â€Å"Come ‘long in, M’sieur Alce.† His voice and her own startled her as if from a trance, and s...

Early warning scores Essay Example | Topics and Well Written Essays - 2000 words

Early warning scores - Essay Example Life of the patients would be at risk if the clinical staff fails to respond to the deterioration of cerebral or respiratory function and increased level of medical intervention, it may lead patients to cardio-respiratory arrest. Abnormal biochemical or physiological variables might lead to avoidable death if appropriate action in response of the above is not taken. Inappropriate care prior to admittance to a critical care unit can direct to more casualties. Due to the limitations of resources, numerous patients that can be treated and monitored in the high dependency units (HDUs) and intensive care units (ICUs) is limited. Therefore it is crucial to select the patients who might benefit from the critical care. The pre-ICU resuscitations might be reduced to an extent if the identification of medical in-patients is carried out at an early stage by the means of uncomplicated procedures bottomed on the physiological parameters (Bowler & Mann 2008, pp.1). For bedside evaluation, Early Wa rning System is a useful tool which is based on five of the physiological parameters: rate of pulse, rate of respiration, systolic blood, AVPU score and temperature. Modified Early Warning System is capable of finding deviation from normal blood pressure of patients and its urine output. To spot surgical patients who would gain benefit from intensive care has been demonstrated recently. No other scoring system which exists has been validated in patients who are admitted on an unselected medical take. The basic goals for this research were ensure the following. 1. To examine the capability of a EWS that is modified (MEWS) 2. To examine the patients that are at risk 3. To inspect the viability of MEWS as a selection device to activate premature evaluation and admittance to an ICU or HDU Effectiveness and Impact All the data of the emergency admissions that were admitted to Medical Admissions Unit was collected. This was done in the month of March and the patients who were admitted to Coronary Care, Medical HDU or ICU and the ones who were admitted again during the study were not observed. While performing routine duties the nursing staff gathered i data, after attaining formal training. Demographic facts, rate of pulse, rate of respiration, systolic blood, temperature and AVPU score (A for ‘alert’, V for responding to vocal stimuli’, P for ‘responding to pain’, U for ‘unconscious’) were evidenced on admittance. Pulse rate and blood pressure were calculated by machine (DINAMAP, Critikon) and also checked physically where suitable. The measurement of temperature was done orally (Temp?Plus II, IVAC). The rate of pulse was counted over sixty seconds. At the time of the measurement of blood pressure, the AVPU scores were scored according to most excellent response. Physiological parameters were collected by the nursing staff twice daily (once am and once pm) on a sheet of data collection for a up to five days. The two inv estigators (MK, CS) were responsible to check the completeness of data every day. The data which were collected was utilized to calculate a Modified Early Warning Score (MEWS), from prior experience it was decided to describe a MEWS of 5 or more as a ‘critical score’. During the admission the score that reached the highest was tagged as ‘Score Max’. HDU admission along with ICU admission was the primary end points. Moreover, the other points included the attendance of the cardiac arrest team at a cardio respiratory emergency and

Research Proposal Draft - Essay Example There are also few studies that indicate the way in which these youngsters can be motivated to adopt a positive lifestyle in terms of being physically active and eating the proper diet that will help them to avoid obesity. There exists a desperate need to identify a connection between the benefits that come with weight loss. There is also a need to make sure that people, especially the young people are not only aware of the health benefits of losing excess weight but that they are motivated to lose the excess weight through positive lifestyle and the proper eating habits. The significance of the current research study is to measure how a quantitative weight loss program will affect those who will be involved in the study. The study will involve 50 participants of ages between 8 and 18, from both the genders. All the participants have to have a body mass index of over the 95th percentile which is a clear indication that they are obese and overweight. The study will be done in a period of twelve weeks. The study will monitor food intake, oxygen saturation, blood pressure, heart rate, blood glucose and cholesterol levels of the participants. Will there be increased positive health benefits such as, improved oxygen circulation, healthy blood pressure, heart rate, blood glucose and cholesterol levels, in the participants who will be children age 8 to 18 with a BMI above the 95th percentile? The hypothesis for this research is that there will be clear indication of the positive health outcomes that will be achieved by the 50 participants who will be involved in this controlled medical study for weight loss. Needles to say, age is an important factor when weight related health issues are being considered. The way an 8 year old child can be affected by overweight may not be the same way s an 18 year old will be affected. At the same time, the way an older patient may be able to stay in course in a controlled weight loss progress is not the same way a young

I would like to express my deep gratitude to my supervisor, Mr. Mohd Khanapiah Bin Nor for guiding me to complete this project. He was giving me necessary information regarding the project and a lot of inspiring ideas. My appreciation also gives to my beloved parents, family members, and friends who have been behind me throughout this project for the encouragement and supported from them. I really appreciate all their help and support while I’m completing this project. Lastly, I would like to sincerely thank Universiti Teknikal Malaysia Melaka (UTeM) for providing the facilities and equipment for me to complete my project. In the previous era, the technology application mostly using wire but now a wireless device has become commonplace. The wireless sensor network can be defined as an application that having no wires connection on that devices. In addition, to make the system easy to monitor from a distant location, the RF 433MHz module was used. So, this project gives the idea for studying details about the RF 433MHz module performance for WSN application. 1.1 Project Background Nowadays, using the wireless sensor network (WSN) technology to monitor the environment helps someone to solve the problems of deployment difficulty, high cost, and realized unmanned monitoring which is mostly used in a factory, buildings, laboratory, and house. This project is to study the range and performance of the RF 433MHz module for WSN application. RF 433MHz module is popularly used in the remote control system. This range also available to use in this area. There are two types of the RF module which is transmitter and receiver. From research, using RF 433MHz module, the data can get more accurately without any data losses with the range that given than compared to another transmission for the wireless sensor network. The range that can reach by this RF module is different between outside and inside area. For inside area, it can work for 50 meters through multiple walls with an antenna, while for the outside area, it will be able for hundreds of meters. Besides that, a microcontroller such as Arduino also used in this project. Arduino that available for this project is Arduino PRO which is it has 3.3V port that will be easier to connect directly to the types of RF 433MHz module that used in this project. This project also will be studied the analysis of the data transmission by giving a few of distance between the transmitter and receiver of the RF 433MHz modules when located in the obstacles or line of sight area. Then, the data that are received will be displayed on the computer whether there are data losses or not. The problem that becoming as issues right now is there is a lot of ways to send data but the problem is about the range, cost, and data losses. So, for this situation, study the performance of RF 433MHz can overcome the problem for the WSN application. The objectives of this project are to understand the range and performance of RF 433MHz module. Moreover, exploration about the transmitting and receiving the data by using the RF 433MHz module. The main work scope of this project is to make sure this project will achieve the objectives. The main focus of this project:- i. To study and understanding the range of RF 433MHz module. ii. To transfer data by using RF 433MHz module. 1.5 Methodology In this project, there is three part that needs to follow. For the first part, it will be focused on the conducting the literature review and do some research more detail about the RF 433MHz module. Meanwhile, for the second part, after the software development process, the hardware development process will take over and include the testing of the project. Last part, when the hardware and software complete their part, it will be followed by testing the performance and the operation of the project to make an analysis. The methodology is the explanation of the procedures or steps when doing this project. The simulation, analysis, and evaluation of the project. A literature review is an important step before proceeding to the project. Collecting all the required information about the 433MHz RF module from the books, journals, and website. The literature review also can provide a useful information to complete the project. The idea for this project comes from the problem faced when the data that have been transmitted becomes losses with the range that provided. In this chapter, it will be explained more details about the project and also the components that will be used in this project. The frequency of 433MHz that used in the wireless sensor network can test the sending and receive the data for this range without any data losses. 433MHz RF modules required the 17cm of the antenna to support the range to send the data. The range is one of the most important parameters of any wireless system which is it defined how the transmitter and receiver can be apart from each other to send the data. A range of the outside with few obstacles the data can go through hundreds of meters. While for the indoor, the data can go over 50 meters through multiple walls. The external antenna will be soldering to the â€Å"ANT† on the transmitter to get more range which is 17cm of the length of the antenna that was used. Regarding the several research that I have done from a few of journals that can relate to my project. Wireless sensor networks are currently widely used in several of monitoring and control applications. Guohua Yang and Kui Zhang (2015) have conducted a project regarding the 433MHz radio for long-range communication. They present about the connectivity, range of the communication and packet loss ratio that have been performed in the indoor and outdoor environment. The Maarten Weyn and Glenn Ergeerts (2013) conducted the survey of the DASH7 Alliance Protocol for wireless sensor network (WSN). In this research, it stated that 433MHz is an unlicensed band. They said that, due to the frequency, it has a better propagation characteristic opposed to the higher frequency. The wavelength at the center of frequency is 69.14cm which is the bandwidth for the frequency is 1.84MHz. This limits the data rate of the communication at this frequency 433MHz is an ideal for low power of low data rate communication. Budi Setiyono, Sumardi, and Rafdito Harisuryo (2015) have conducted a project on measurement system of temperature, humidity and air pressure over 433MHz radio frequency for an application on a quadrotor. They using the telemetry system which is the measurement process of data at a certain distance. Then, they stated that data will be processed or analyzed by the receiving station. They stated on their result which is for successful transmission, the amount of data that received will be same as the amount of data that have been sent. This project is to improve the data transmission with 433MHz RF modules either in obstacles or line of sight condition. The 433MHz RF modules are categorized as the lower cost, lower power consumption and the most important is when the longer the distance for data that transmit remains accurate when it received by the receiver. In theoretical, the success of data transmission is the amount of data received will be same as the data that have been sent. That means there are no data losses when the transmission occurred. Radio Frequency (RF) is a rate in the range of around at 3 kHz to 300GHz which is corresponding to the frequency of radio waves, and the alternating current that can carry the radio signals. ITU bandstand for International Telecommunication Union that defined for the electromagnetic frequencies that used for radar and radio. The best set of terms for frequencies used in communication. While the very lowest bands have no radar applications. The table below shows the frequency range and ITU band. The Arduino Pro is a microcontroller board based on the ATmega328. This microcontroller is an open-source hardware and software. The version that used in this project is 3.3V/8MHz. This version can be powered by a battery or external power supply. It has 14 digital inputs and output pins which is 6 of it can be used as PWM output, another 6 pins for the analog input, battery power jack, an ICSP header and reset button. Arduino Pro needs to connect with FTDI cable through six pins header to provide the USB power and have a communication with the board. Arduino Pro has the port for 3.3V that can supply the voltage for the transceiver. Each of the 14 digital pins on the Arduino Pro can be used as an input and output which is operated at 3.3V. Each of the pins can provide or receive a maximum of 40mA and has internal pull-up resistor (disconnect by default) of 20 until 50 kohm. The ATmega328 has 32KB and running 8MHz of the external resonator. It also has 2KB of SRAM and 1KB of EEPROM that can read and written with the EEPROM library. The operation of the Arduino microcontroller is based on the connection made on the pins. The application can be done by using the Arduino software where Arduino function can be edited according to the applications in this software. This software can work on by using the C or C++ language. The program that has been creating the need to upload to the microcontroller by using the USB cable. If there is an error detected on the program, it will be adjusted by editing to make a correction on the process and then the program needs to reload again. Other than that, there is another option which is using the reset button to delete all the previous program that have been upload before this to make it clear then built again. MHz RF Module version that has been used. It is because can operates in the unlicensed ISM (Industry Science and Medicine) radio band. It’s available for use in the inexpensive area for short-range wireless networks of sensors. This types can operate on the 433MHz frequency and can capable of transmitting at up to 100mW and up to 300kbps. When increasing the transmit power and reducing the data rate it can maximize the range of the 433MHz. DHT11 is a digital temperature and humidity sensor. Its suitable for my project that only needs to read the data about the temperature and humidity only. Micro-B is the smallest USB connector type. This type also used for the android as a cable for charging while USB port A is that can connect to PC or laptop. This USB cable needs to connect the RF transceiver module with the Arduino Pro at the transmitter and receiver. Using this board because the standard FTDI board cannot supply the enough current to run the RFM69 433MHz RF Modules. The difference between standard FTDI and Beefy 3 FTDI is the current that can provide which is standard FTDI provide 50mA while Beefy 3 FTDI provides up to 500mA. This chapter will be discussed the procedures and steps that used in this project. Each of the methods that were used to achieve this project will be stated and explain briefly. The purpose of the methodology is used to achieve the objective that has been stated. 3.1 Software Design In this part, the software design is part to do the programming by using the Arduino software. The flow of the data transmission starting from the reading of the temperature and humidity by using the DHT11 sensor. Then, the data will be processed by a microcontroller. It will be sent through the transmission of data by using the 433MHz RF transmitter module. When the power supply is turned on, the 433MHz RF receiver module and the microcontroller ready to accept the data that have been transmitted. After that, the data is sent by the Arduino microcontroller via a serial port to the computer for displaying the data. Based on Figure 1 and Figure 2 it showed the flow how it works. Hardware design consists of two parts which are from here it will be explained how the flow of the project will be complete. For the first part as shown in Figure 3.3 is the data obtain from the DHT11 sensor reading, then the data will be transmitted by the 433MHz RF transmitter modules. While for the second part as shown in Figure 3.4 is the data received via 433MHz RF receiver modules then sent by the Arduino PRO that connected to a computer for display.
