Critical Response Essay Free Essays

In the article â€Å"Pandemic or Panic† (2010) by Brian Molloy and the article â€Å"Hindsight is easy† (2010) by Erica Grove, the two of them examine the way WHO reaction to the flare-up of H1N1 flu and they present alternate points of view on how the cash was spent on and how the asset was disseminated. Molloy is impartial about the WHO’s reaction of H1N1 flu episode, while Molloy is exceptionally doubtful. Initially, Molloy contends that WHO send everybody into a frenzy about H1N1, yet it isn't the danger individuals imaged it to be. We will compose a custom exposition test on Basic Response Essay or then again any comparative point just for you Request Now Woods, notwithstanding, states that it is vital for the WHO and the legislature to takeâ the danger of H1N1 genuinely. Next, Molloy claims that British government spend a great deal of cash on immunization which makes two significant pharmaceutical organizations acquire billions from pig influenza, and there is an irreconcilable situation between the administration and medication produces. He accepts that this cash ought to be spent on a correct circumstance like crippling as opposed to rewarding influenza. Forest additionally accepts that there is a bungle of the dispersion of antibody. Conversation: Molloy claims that the WHO and the administration spends enormous use on portions of antibody, while the demise rateâ for H1N1 is far low than for normal flu. He condemns the reports of H1N1 cases are overstated which send individuals into a frenzy about H1N1. Paradoxically, Grove expresses that the WHO didn't blow up to the emergency. Or maybe, she feels appreciative that the specialists paid attention to the danger of a pandemic. She likewise calls attention to that everything is in every case preferred to overprepare over to underprepare. Molloy seems to have disregarded that the incredible of infection can be. Truth be told, there are two or three variables like infectivity, seriousness and lethality which would all be able to influence the quality of an infection. Transmission is additionally a key factor to decide how the infection spread and be distinguished. As Molloy specifies that the passing rate for H1N1 is generally low than for standard pandemic, it doesn't imply that H1N1 is a frail flu. Maybe the low demise rate is because of early follow the source, contaminated individuals are all around confined from the remainder of the network so as to control the spread of H1N1, or blend of another antibody by researchers in a brief timeframe. These could be one reason of why the passing rate for H1N1 is low. In this sense, Molloy neglect to see that. The most effective method to refer to Critical Response Essay, Essays

Essay on Mental Illness and Society - 1388 Words

This essay will focus completely on Mental illness in the UK. To gather my research I used various resources such as websites and books. I have also viewed YouTube videos in order to expand my knowledge. The statistics gathered may not be totally accurate in discussing mental health within the UK for the sources are secondary but it is reliable for giving a view of what the distribution is like amongst gender, age, class as well as ethnicity. When looking at the British society, mental health disorders are actually extremely common. When viewing the National Statistics, it stated that about one in six adults will have a mental health problem. Leading to an additional study, stating that around 30 individuals out of every 100 will†¦show more content†¦The spread of mental illness continues to be of concern especially in Britain. For statistic say that 70% of the prison population has a mental health disorder. As known, there are a high quantity of mental health disorders. As each 7 year period arrives, the English government do a survey in order to measure the various disorders which are common in our society today. This survey was done in 2009 and reported that for depression 2.6 in 100 people were diagnosed. As for anxiety, 4.7 in 100 people, phobias, 2.6 in 100 people, OCD, 1.3 in 100 people, eating disorders, 1.6 in 100 people. This survey also covered bipolar, schizophrenia and personality disorders. It enclo sed that as for personality disorders, 3 to 5 people in every 100 are suffering. Another concern is the distribution of mental illness across the UK.

Geomechanics Lab Report Free Essays

Aim The main intention of this investigation was to determine the various stages of the Atterberg Limits. These included the liquid limit test (LL), plastic limit test (PL), plastic index test (PI) and linear shrinkage (LS) of a soil sample provided by the administration. This was then followed by a sieve analysis to determine the particle size distribution of another soil sample so that a suitable classification in both situations could be made in accordance with the Australian Standards AS1726 – 1993. We will write a custom essay sample on Geomechanics Lab Report or any similar topic only for you Order Now Procedure (Sample preperation) On commencement of the experiment, each group was provided with two parts of 500grams of soil retrieved from the field and then oven dried by the experiment supervisor. One part of the soil sample was coarse grain gravel for the particle size distribution chart and sieve analysis, whilst the remaining 500 grams of soil was of fine grained fraction. * Preparation of Coarse Grained Fraction During this procedure the mass of 500grams of soil was recorded and soaked in water for duration of 24 hours. This was then followed by placing the soil sample into a 0. 75mm mesh sieve and the entire fine particle was washed away using running tap water and a small spray bottle until the water had started running clear. The sieved sample was then transferred in a tray which was again put into the oven at 100 degrees for 24 hours. * Preparation of Fine Grained Fraction The remainder of the 500 grams of the sample was then sieved through a 0. 425 mm mesh sieve and the contents collected. This procedu re was done until approximately 150 to 200grams of material was successfully passing sieve. Procedure (Sieve Analysis) This procedure involved the sieve analysis of the coarse fraction. This involved weighing the mass of the oven dried coarse grained fraction so that we are able to determine the particle size distribution. For this experiment the mass of coarse fraction used was 312. 10 grams. This was then followed by arranging the sieves from top to bottom in order from larger gapped mesh in the sieve to the smaller one (i. e. 37. 5mm to 0. 075mm) and then pouring the sample in the top sieve whilst shaking it for approximately 10 minutes. This provided mechanical energy to the soil allowing for it to pass all the sieve layers. The next procedure involved recording the soil mass that had accumulated on each sieve and the bottom pan. Furthermore the percentage of original mass retained and cumulative passing % vs. particle size plot has been constructed as shown in Appendix A. As shown in the plot it can be noted that the results obtained were not accurate enough for the effective size values of D_10 and D_30 to be calculated. Yet the effective size D_60 was able to be found and was shown to be 1. mm as shown in the particle size vs percentage passing table in appendix A. Due to the fact that all effective size values have not been able to be attained from the graph, the uniformity coefficient C_u and the coefficient of curvature C_c were not able to be calculated. Yet if they could be then they would be calculated using these equations: Cu=D60D10 Cc=D102D10*D60 where CU=Coefficient of Curvature Cc=Coefficient of Curvat ure All values recorded have been further discussed in the results section of this report. Procedure (Atterberg Limits determination) * Liquid Limit (LL) The liquid limit test west performed on the fine Sandy soil over the course of two sessions to determine the water content (percentage) at the point when the soil started to behave with liquid qualities. This test procedure involved gradually adding water to a round well created in two thirds of the soil sample on a glass plate. Then using two spatulas the sample was mixed until a smooth paste was formed. This was then followed by placing a small amount of the sample into the liquid limit device and leveling it horizontally using the spatula to create a smooth surface. Using the grooving tool the sample in the cup was divided in half. To determine the number of blows the handle of the mechanism was rotated at a speed of two blows per second and the number of blows recorded until the soil closed the groove to a length of 1 cm. It was expected that the number of blows be as close to 25+ or – 3 as possible. The group was successful in our fourth attempt where 28 blows were recorded. Once the sample was successful it was removed from the liquid limit cup and placed within a tin and the mass weighed. This was determined to calculate the moisture content percentage. The mixture in the liquid limit range was placed in a 0. 25 meter length mould with a internal diameter of 0. 025 meters and left on top of the oven so that the linear shrinkage could be determined. All values obtained are discussed in the results. * Plastic Limit (PL) To determine the plastic limit (as a percentage), after which the soil could no longer be deformed; water was added to the remaining one third of the dry soil on a separate glass plate and molded by hand. Small amounts of the soil were rolled on the flat glass plate until they formed into a diameter of 3 mm and then started to break apart. According to AS12989 it was proved that the soil had reached its plastic limit. This soil was then placed in a tin and similarly to the liquid limit all mass values of the tin and sample were recorded. These were left to dry in the oven. All results obtained the following day have been discussed in the results section. * Linear Shrinkage (%) As instructed, results for the linear shrinkage were collected after duration of 24 hours from the laboratory and the linear shrinkage (in percentage) was calculated using the formula: LS=LsL*100 where Ls=Recorded Shrinkage L=Initial Length of Sample In addition to the linear shrinkage, all dry mass results were also collected from the previous day and recorded as shown in the results section of this report. * Plastic Index Conduction of the plastic limit and linear shrinkage test led to the calculation of the moisture content in percentage and this further allowed us to calculate the plastic index using the formula. Ip=Wl- Wp where Wl=Liquid Limit Wp=Plastic Limit * Classification of Soil After the soil tests have been completed as listed above and results obtained, the soil sample was classified according to the Australian Standards AS1726 – 1993. To aid in this classification of the soil, table 8 (Identification and Classification of Coarse Grained Soils) and table 9 (Identification and classification of Fine grained Soils) as well as Graph 1 (Plasticity Chart vs. Liquid Limit) have been used and attached in Appendix C. Further criteria such as Plasticity of Fines, Color of Soil, Cohesive strength and Classification Group symbol (Table 7 Soil Classification Symbols) can also be used.

Then as extra dry soil was added to the sample the number of blows gradually increased allowing for a result acceptable within the 25 + – 3 limit was met in test 4 Hence the soil sample’s LL can be taken as 68. 64%. * Atterberg Limits Determination (Plastic Limit) Plastic Limit| Test no. | Test 1| Tin #| 16| Mass of Wet Soil and Tin| 37. 06| Mass of Dry Soil and Tin| 34. 5| Mass of Tin| 23. 94| Mass of Moisture | 2. 56| Mass of Dry Soil| 10. 56| Moisture Content| 24. 24%| Avg.

The result as shown above in table 6, the soil has shrunk 32mm in length and cracking of the sample has occurred. The same has not crumbled at touch and has not shown any curling effects. The Overall linear shrinkage is calculated to be 12. 60%. LS=LsL*100 LS=32254*100=12. 60% Discussion The classification of the Coarse and Fine Grained soil was made according to the Australian Standards as1726 – 1993. All justification of the results and classifications of the Sieve Analysis and Atterberg Limits have been made through the combination of the identification and classification tables in the appendix. Coarse Grained Soil As per the Particle size plot in the appendix, the sample is shown to have only coarse grain materials. Consisting of 22% Gravel (7% Medium Grain and 15% Fine Grain) and 38% Sand (22% Coarse Grain, 13% Medium Grain and 3% Fine Grain), indicates that the soil is widely distributed and hence making it a Gravelly SAND. * Fine Grained Soil Using the Atterberg Limits to find the Plastic Limit and Liquid Limit percentages, these were applied to the Plasticity vs. Liquid Limit Chart (AS1726-1993) to determine the classification of the soil sample. As the intersection point is below the â€Å"A† line with a high liquid limit of 68. 64%, the reaction to shaking was low to none and the toughness is low, the classification of the soil sample is most likely to be MS-SILT Highly Plastic. Also according to the Australian Standards the color of our soil was Brown mottled red-brown. Since the fine grained soil was cohesion less and free running we can classify the soil as dry. In accordance to the Plasticity vs. Liquid Limit chart the soil is of High Plasticity as the liquid limit was of a value greater than 50%. In addition to the above, the particle size distribution curve is also widely spread so the soil is classified as â€Å"Well Graded†. Conclusion In this experiment we used the Sieve analysis and Atterberg Limits tests to investigate the properties of the soil as mentioned in the Australian Standards AS1726 -1993. In addition sample tests were conducted including the liquid limit test (LL), plastic limit test (PL), plastic index test (PI) and linear shrinkage (LS) of the soil sample provided by the administration. All results obtained have been justified and the classifications of the soil made in accordance to the Australian Standards 1726 – 1993.

Objective of a 42% CO2 emissions decrease by 2020 and an 80% CO2 emissions decrease by 2050, supported on 1990 baseline. In addition, the Scottish Governments agenda of ecarbonisation pertinent to the Heat and electricity Generation Policy Statement sets the alternatives to bring explanation to help with the subsequent: heat system decarbonising dropping dependency on fossil fuels dropping pressure on family energy bills and grabbing economic opportunities delivering electricity use from renewables hold up the main position for renewable energy in supply of electricity by thermal generation power stations with Carbon Capture and Storage mainly decarbonised electricity system resourcing 11% of heat requirement and 10% of convey fuels from renewables by 2020 facilitate local and community possession of renewable energy tumbling final energy consumption in Scotland Demand for clean energy There is a primary concern concerning harnessing these kinds of forces in an era which is extremely aware of the ecological possessions of smoldering fossil fuels and maintaining is a moral norm. So nowadays the center is on together sufficient amount of energy provided for long use and as well the ecological inference of meticulous foundation. In that look upon the close to confidence of expenses being compulsory on carbon dioxide release in urbanized country at smallest amount has deeply distorted the financial viewpoint of fresh energy sources. Sun, current of air, waves, stream and the warmth from decay of radioactive in the mantle of earth as healthy as biomass are the entire plentiful and continuing, therefore the word "renewable". merely one, the control of declining water in rivers, have be considerably tap for electricity for a lot of years, although use of wind is growing quickly and it is at the present recognized as a typical source of energy. Solar energy is major individual request has been in farming and forest, by means of process of photosynthesis and more and more it is tie together for heat energy. Further electricity residue a place request for solar is be ablaze wherever it be able to be utilized. Revolving to the make use of plentiful renewable sources of energy additional to the significant hydro used for electrical energy; present are confronts in fact harnessing them. Not together from solar photovoltaic (PV) that construct electricity straightforwardly, the query is how on the way to create them to twist dynamos to produce the electricity. Condition it is warmth which is tied together by means of a fog producing system. If the basic occasion of these renewable be profusion and comparatively extensive amount, the primary confront, particularly for electrical energy contribute, is relate them to get together the requirement given their changeable and different past. In this manner however that there have to be dependable reproduction sources of electrical energy further than the standard system set aside, or a number of ways of electricity storage space. However, a separate benefit of solar and to a number of degree additional renewable systems is that they are dispersed and might be closer to the summit of requirement, thus dipping power broadcast fatalities if customary producing plants are far-away. Obviously this similar characteristic from time to time add up alongside wind in so as to the most excellent place for tie together it are now and then distant from inhabitants, and the major help for be short of wind in single place is wind waft firm in one more, hence necessitates a broad network with supple operation. There is important extra capacity in growth from corner to corner of Scotland, with projects moreover in planning or by now permission which now sum over 12GW. Once more, capability boost in the short term will draw closer from onshore wind, with in excess of 4GW of ability by now consented and an additional 3.6GW in preparation. In the long expression, in excess of the subsequent decade, we might see main boost in offshore wind, by means of over 4GW before now consented. There is as well 244MW of bioenergy schemes at a variety of phases of expansionand 187MW of wave and tidal schemes moreover in planning or by now consented. Electricity Capacity Electricity capacity of Scotlands renewable energy has revealed steady growth more than 8 years having standard annual capacity augment over 650MW ever since the end of 2007. Whole Installed capability in Scotland for Renewable Electricity 2007-2014 Operational capacity Pre-operational Capacity of Renewable Projects Current Installed Capacity of Renewable Electricity (End Q4 2014) Chart above sets current combination of renewable electricity creation capability in Scotland. By means of the total now in excess of 7GW, the sector is 2.5 times better than it was at the end of 2007. Onto dry land wind is the major single technology, contributing for over 69 per cent of put in capacity, at the same time Scotlands other main basis of renewable power are hydro, offshore wind and bioenergy. Renewable energy sources Hydro Electricity Hydro-electric power, by means of the latent energy of stream is through distant the best-given ways of electricity production from energy sources of type renewable. It equipment over 16% of planet electrical energy on or after 990 GWe put in capability at the conclusion of 2014. Partially this comes in five nations: Separately from individuals four countries by means of a comparative profusion of it like Switzerland hydro ability is usually functional to peak-load stipulate, since it is so willingly stopped up and in progress. This signifies the wind energy efficiency in Denmark has increased. Hydropower by means of great storage space reservoirs is not a main alternative for the prospect in the urbanized countries since most main sites in these nations have probable for harnessing seriousness in this method are moreover being browbeaten previously or are engaged for other causes such as ecological deliberation. The main benefit of hydro schemes is their ability to switch cyclic (in addition to daily) elevated peak loads. By putting into practice the operation of stock up water is from time to time complex by difficulty for irrigation that may take place away of stage with max out electrical load . Wind Energy Consumption of wind energy has increased from the previous consumption rate for these running years, with yearly increment of the wind energy capability it is around 20% for increase in this particular year. Turbines used for Wind with capacity up to 6 MWe are at the present executing in a lot of countries, although the majority of novel ones are having capacity of 1-3 MWe. Power production is a purpose of the chop of the current of air speed, so replication like two times the wind speed provides eight times the power budding. In process like turbines necessitate a wind in the variety of 4 and extends upto 25 metres for each second and thus 14-90 km/hr, with utmost output life form at 12-25 m/s the surplus energy life form drop above 25 m/s. At the same time as comparatively hardly any areas contain important current winds in this variety, a lot of have sufficient to be harnessed efficiently and to provide improved than a 25% capability utilization. Biodiesel A variety ofbiodieselsystems subsist at nearby, and as with mainly renewable. A biodiesel fuelled vehicle by the remaining vegetable oils out of the Orkney archipelagofish and chipoutlets. Wave and tidal energy Scotlandhas a predictable25% of Europe's tidal prospective and 10% of its potential for wave. There have been additional grid-connected maritime energy converters organized at EMEC than at any additional single site on the earth and the centre leftovers the worlds only attributed marine energy laboratory. Merit comparison The main benefit of hydro schemes is their ability to switch cyclic (in addition to daily) elevated peak loads. By putting into practice the operation of stock up water is from time to time complex by difficulty for irrigation that may take place away of stage with max out electrical load. Wind energy is variable in nature hence imposes some limitations on the production and thus imposes various constraint. Bio fuel energy does need some more sources and need more concern. Like wind wave and tidal energy is also variable in nature. Thus imposes many constrains. Scottish targets Scotland's capability to provide enough renewable heat and electricity to complete its objectives in a lucrative way depends significantly on dropping demand. High requirement needs more generating capability to be built. Due to reservations over character behaviors, electricity requirements could differ but it is probable to increase in the long run as superior use is complete for transport and heat - consequently energy efficiency dealings to reduce this increase in requirement will be vital if electricity is to stay reasonably priced. Attaining energy competence will be essential to meet up the Scotland Act of Climate Change 2009. Objective of a 42% CO2 emissions decrease by 2020 and an 80% CO2 emissions decrease by 2050, supported on 1990 baseline. In addition, the Scottish Governments agenda of ecarbonisation pertinent to the Heat and electricity Generation Policy Statement sets the alternatives to bring explanation to help with the subsequent: Psychoanalysis by the buy and sell body Scottish renewables demonstratesthat renewables shaped almost one third more power compared to nuclear, gas or coal in the primary six months of the year, producing 10.4 terawatt hours (TWh) throughout the six-month period. Conclusion Renewable sources of energy in Scotland have taken responsibility precisely for the task it was intended to do like flourishing more jobs, protected supplies for energy and, mainly dropping our carbon emissions to assist in binding the change in climate. Scotland's capability to provide enough renewable heat and electricity to complete its objectives in a lucrative way has provided a new direction and hope for the world. References 1.
