How health psychology research might contribute to solving health Essay

How health psychology research might contribute to solving health problems associated with socioeconomic disadvantage - Essay Example These health problems could be understood from a much narrowed down perspective – one that is significant to the whole related discussion. The patients who have socioeconomic disadvantages are the ones who suffer the most because they have lack of resources available at their disposal and this means that they seem to miss out on a number of health benefits which the state (the public sector) or the private sector has brought forward for them. Socioeconomic disparities could play havoc with the mental and physical self of the patients in a very drastic manner. It hampers the manner under which patients could manifest their health basis with the money that they have to take care of their lingering health related problems. They usually measure up their ailments in the light of the money that they could muster in order to bring a remedy for the same. (Stecklov, 2001) The state has a huge role to play in changing the way people think. This could be done if proper facilities could be made available and if there are adequate arrangements to take care of the potential health threats that the deprived individuals can face with the passage of time. Research in the health psychology domains would reap rich dividends. The reason for the same is that it will pinpoint the grey areas as well as find out the exact problems that owe a hand or two towards the declining regimes of health basis within the people who are at a socioeconomic disadvantage and loss within any society. It will examine the exact basis of growth within these problems and look to solve the same in the light of the present day case studies. (Repper, 1998) It will seek help from researchers in the same field and understand the rationales behind socioeconomic disparities and how the two work hand in hand (in a negative connotation) towards the deterioration of health standards within a society to say the

Acoustic Emission and Vibration Essay Example | Topics and Well Written Essays - 1000 words

Acoustic Emission and Vibration - Essay Example The process of early detection has proved to be a very crucial factor in condition monitoring as well as serving as a basic extended CBM component (Zamada and Masuda, 1999, p. 160). Though the two sensors are effectively applied in this process, there exist several differences in their applications as well as a number of advantages and disadvantages over each other. The acoustic emission normally abbreviated as AE refers to sound waves that are normally produced in the event that a material is subjected to stress due to internal changes and external forces. A good example of this phenomenon is the mechanical loading which generates elastic wave’s sources (Lokajicek and Sikula, 1996, p. 312). Over the years, acoustic emission has steadily replaced the use of vibration techniques that were used traditionally. This transformation is closely associated with the better working conditions witnessed while working with acoustic emission. Vibration sensing has been associated with a nu mber of mechanical conditions such as processes that result in energy loses like friction and impacts, machinery deteriorates, and frequencies that come in a broad range. Acoustic emission on the other hand makes use of much higher frequencies when it comes to vibration movements that are synchronous. By using such frequencies, this technique makes it possible to detect signal parts experiencing high signals and also allows the detections of miniscule activities that come in large amounts like brief impacts, slight rubs or crushing of single lubricant particles. This means that acoustic emission technique is in apposition to detect failures that are impending before they take place and goes further to monitor their progress afterwards (Mori, Saruhashi and Mogi, 1994, p. 375). Though vibration analysis has been in operation for many years, it is associated with a number of disadvantages including its knowledge levels that are unsustainable and its requirements being costly while tryi ng to achieve a good diagnosis. The above setbacks make vibration analysis valuable but overly complicated compared to acoustic emission. Acoustic emission offers detecting warnings early enough on small defects and wear while vibration sensing has to wait until a defect occurs before it detects it. Acoustic emission technique also picks up more information as compared to vibration sensing. Some of the additional information picked up by acoustic emission include; friction, lubrication and cracking. Vibration sensing is in no position to pick up such information. Despite this realization, it is evident that the total information that can be picked by acoustic emission is limited as compared to that obtained by vibration analysis (Mori and Obata, 1998, p. 340). The Differences between Acoustic Emission Sensor and Vibration Sensor The acoustic emission signal processing is complicated in such a way that it cannot be conducted by every individual due to its high frequency signal. It ca lls for expertise in the interpretation of the oscilloscope’s squiggly lines. This technique allows machines to be run continuously, slowly, for a duration that is short and to be operated intermittently. Acoustic emission also permits for problem diagnosis on machines to be carried out in its early stages, gives room for maintenance procedures and allows for the monitoring of the improvement. By allowing such procedures and process, the technique provides early information that is real time on faults applicability and sensitivity to a broad speed rotational (Simpson, 1991). Contrary to vibration sensing, acoustic emission
