The Issue Of Same Sex Marriage - 1286 Words

Equality of Love What does love mean if one can’t love the person one wants. For some, love comes easy , meaning they have that ideal relationship, the relationship that is â€Å"morally right†. When speaking on gay marriage, there are typically two views. To some it is just absouletly disgusting, and then to others it’s a beautiful thing. â€Å" Opponents of Same Sex Marriage say marriage is between a man and a woman and anything else is morally wrong( â€Å"At Issue : Same Sex Marriage†) As a human being , whose right is it to tell someone who they can and can not love. Sometimes people may disagree with gay marriage on a spiritual level, but who is to say one person’s sin is less then the next person’s sin? Gay marriage is a beautiful thing, and any human should have their rights no matter who they love. As a human, one deserves to be happy. For many homosexual couples, that may not be the case. With the issues of , same sex marriage, L BGT rights, and gay adoption in general all humans should be able to enjoy the same rights. Marriage is a unity between two people. It may be a hetertosexual couple or it may be a homosexual couple , that choice should be left up to the two people who decided to join in unity. They argue that allowing homosexual couples will destroy the sanitity of marriage ( â€Å"At Issue : Same Sex Marriage†).

Drug Addiction - 866 Words

Drug Addiction: Disease or Habit? When people hear the words drug addict, these words have negative connotations and stigmas attached to them. People visualize a person who does not care about anything, including family, work, or commitments, except for obtaining money to buy drugs to get high. However, there are many people who are drug addicts that maintain a normal, functional life. Most people who are drug addicts would give anything to kick the habit; they do not enjoy the high anymore. The problem is, they can’t. Addiction, defined by Webster, is a compulsive need for and use of a habit-forming substance characterized by tolerance and by well-defined physiological symptoms upon withdrawal. So, if the addicts want to stop, why can’t†¦show more content†¦This way, I can convince the readers that drug addiction is more than a habit, and can be considered a brain disease. I will use the information I gained in my psychology class in college where we spent a l ot of time going over the science side of addiction and what it does to the brain. It allowed me to see addiction as a brain disease rather than a compulsive habit and that helped me deal with the loss of my friends. I will explain the way that prescription pain killers mimic the endorphins, the body’s natural â€Å"feel-good† chemical and how the brain will eventually become tolerant to the â€Å"fake† endorphins and depend more and more on pain killers to keep from experiences withdrawal symptoms. Nowadays, it seems like there is a pill for everything. The media tries to convince consumers that they need a pill to cure ailments they didn’t even know they had. Also, doctors have been irresponsible when it comes to prescribing habit forming drugs, especially to young adults. I have a friend, Brandon, whose leg was run over by a tractor when he was eighteen years old. The doctor prescribed him an extremely high dosage of pain killers and before he knew it, he had developed a high tolerance for them. Once his leg was healed, he wanted to stop taking the pain killers, but his body went through a state of withdrawal. He wanted to stop taking the pills so bad that he checked himself into rehab.

Planet Boundaries Implications Impairment â€Myassignmenthelp.Com

Question: Discuss About The Planet Boundaries Implications Impairment? Answer: Introducation According to IAS 36 Impairment of Assets, it is assured that an asset is not brought on the balance sheet statement at a value, which is greater compared to the recoverable amount of the stated asset. This essay aims to focus on appraising the situations in which there is occurrence of impairment loss along with explaining the time the organisation needs to perform the impairment review of assets. As commented by Baboukardos and Rimmel (2014), impairment is expected to happen at the time the carrying amount is greater in contrast to recoverable amount. The recoverable amount includes the net sales price of the asset, value in use and fair value in compliance with IFRS 13. After the end of each reporting year, an organisation needs to assess whether any indication of impairment is inherent or not. In case, there is an indication of impairment, it is necessary to compute the recoverable amount of the asset (Damian et al. 2014). The realisation of impairment loss is inherent, in which the recoverable amount is lower in contrast to the carrying amount. It needs to be realised immediately as expenditure, unless it associates with a re-valued asset, in which the impairment loss is considered as revaluation decrease. For goodwill, the cash-generating unit to which goodwill has been apportioned needs to be tested for annual impairment by contrasting the units carrying amount along with its recoverable amount. In either situation, if the recoverable amount of the unit is below its carrying amount, the organisation needs to realise impairment loss. In the past, IFRS needs realisation of goodwill subject to amortisation over the useful lifetime (Guthrie and Pang 2013). The impairment indicators are developed in IAS 36 with an intention of minimising the subjectiveness of the decision, which was the case in the past. The unfavourable changes in markets, economy, technology and law could have adverse effect on the asset values of the organisation (Huian 2013). The impairment indicators could be because of external or internal sources. The assets market value might reduce due to usage or the time passage. The other external indicators of a fall in value could be the outcome of important market, technological, economic or legal changes that happen and this would have unfavourable impact on the asset or organisation. The interest rates in the market might have an effect on the rate of discount utilised in computing the value in use related to an asset and therefore, there is decrease in recoverable amount. The internal indicators related to review of impairment could be the outcome of physically damaged or obsolete assets, or if an asset is portion of r estructure or it is held for sale or in which there is poor economic performance of the asset in contrast to the expected performance (Huikku, Mouritsen and Silvola 2017). Despite the objectivity of the set standard, it could be complex to ascertain the value measurement attributable to assess the options related to impairment. The measurement and timings related to write-downs of assets depend heavily on estimates. Certain characteristics of testing related to impairment and process of measurement make implementation a serious problem (Ji 2013). There are many triggering events of indicating impairment and these vary greatly in terms of severity and significance. The various models of valuation are utilised and the conformity is less in the discount rate selection. However, there is a variation in nature, which continues to occur between fair values disclosed on the part of the management. In addition, IAS 36 intends to enhance transparency along with minimising the accounting subjectivity associated with impairments (Linnenluecke et al. 2015). The exercise for ascertaining whether there is an impairment of asset and the amount remains at the discreti on of the management. This standard now aims to address such discretion by needing yearly impairment or reviews of impairment to be conducted whenever there is impairment indication. Even though there is a discretionary element afforded to the impairment computations and therefore, the incentives of the management in managing earnings could play a role in the decisions of impairment. These projections might be handled for altering or avoiding impairments (Sapkauskiene, Leitoniene and Vainiusiene 2016). This would minimise the comparability across the organisations. For instance, loss related to impairment of goodwill is projected in most cases from the projections of the management of future cash inflows. This could pose serious problems for the investors, as they are not able to vision such potential manipulations. The analysts and investors have the alternative to adjust or ignore the reported accounting numbers. Hence, it reduces the certainty of the reporting behaviour in misleading users or minimising relevance and reliability. Along with this, the financial statements vary from the management accountants used on the part of an organisation and the impact of impairment broadens the existing gap between the accounts of management information used on the part of the board and the audited financial statements. The manipulation of earnings is an issue; however, the judgemental approach to indicate and compute impairment is provided. The managers often receive an economic incentive in manipulating earnings for enhancing their cash compensation. In this case, IAS 36 permits for a judgemental element in the computation of impairments. IAS 36 allows an impairment loss on a fixed asset to be reversed, if the marketing value associated with the asset is recovered. This has direct effect on the impairment practices, in which reversibility has positive impact on the decision of the managers in recording impairment of assets. The permission of reversals increases significantly the probability that a manager would record the impairment. Hence, it highlights the discretion that management could withhold towards the impairment treatment. Thus, it could be concluded that managerial self-interests and concerns pertaining to earnings management seem to motivate many decisions of impairment. In addition, i t has been found out that goodwill needs to be assessed yearly for impairment, while the other potentially impaired assets are reviewed for impairment in detail, if there is any sign of impairment.

Microgrid Essay Example

Microgrid Essay Modelling and Simulation of Microgrid Application at RCET Rana A. Jabbar1, Azah Mohamed2, Muhammad Junaid1, Muhammad Ashraf1, Ihsan Ullah1 1Rachna College of Engineering and Technology, Gujranwala, Pakistan 2Universiti Kebangsaan Malaysia (UKM) [emailprotected] edu. pk ABSTRACT Renewable energy resources have got vital importance in present era as fossil fuel reserves are depleting and their prices are fluctuating drastically. The role of these resources in generation of electricity is inevitable in the developing countries like Pakistan, where energy crisis has become a burning issue due to short fall of electricity. Presently the country is suffering from repeated and shocking black outs. Therefore, the generation of electricity through other than traditional resources has become indispensable. In this research paper an innovative concept has been imparted for the development of Microgrid, based upon locally available renewable energy resources, keeping in view the geographical location of Rachna College of Engineering Technology (RCET), Gujranwala-Pakistan. These available renewable energy resources have been integrated to function as a single generating unit for forming Microgrid. The comprehensive modelling and simulation of Microgrid has been performed using MATLAB. The objective behind the development of this proto type model of Microgrid is to design a standby power for RCET Library in case of electricity failure from National Grid. Alternative Energy Development Board (AEDB) of Pakistan is looking for viable solution to compensate the National Grid and emergency need of individual sensitive consumers since long. Simulation and implementation of this developed model will really be very helpful for all stake holders of power industry nationally and internationally.

Introduction Microgrid is actually assembly of renewable energy resources able to be operational paralleled or independently from National Grid having capacity up-to Distributed Generation (DG). Microgrid is more modern way for utilizing the available potential of DG, not only in remote area electricity development but also in over coming the short-fall of electricity commercially. Most commonly available renewable energy resources, used for the development of Microgrid, are Solar, Biomass, Micro-hydro, Wind, Fuel Cell etc [1, 2, 3, 4]. Like other developing countries, Pakistan is also suffering from acute energy crisis. The present sources for generation of electricity in Pakistan include Hydro (33%), Natural Gas (35. 7%), Oil (28. 7%), Coal (0. 3%) and Nuclear (2. 3%). Despite the massive availability of renewable energy resources, their contribution towards generation of electricity in Pakistan is negligible. The Maximum demand of electricity in Pakistan is about 15,000 MW, whereas supply demand gap is about 3000 – 4000 MW. The renewable resources used in this research work are Solar, Biomass, Micro-hydro and Fuel Cell. Pakistan located in the Sun Belt is ideal for taking advantage of solar energy. The mean global irradiation falling on horizontal surface is about 200–250 watt/ m2 per day, equivalent to about 1500–3000 sun shine hours and 1. 9 – 2. 3 MWh/ m2 annually [5]. Being an agriculture country, sufficient live stock is available for producing enough animal dung to be utilized in the production of biogas. Following the latest statistical data of AEDB, the available micro-hydro potential in Pakistan is about 2000 MW. Moreover, there is an immense potential to utilize the flow of water in world’s largest canal network, particularly in province of Punjab, Pk [6]. This paper presents a novel approach of Microgrid development in which micro-level energy generation resources are first incorporated with each other to form one generating station controlled by a central unit and simultaneously integrated with National Grid for both way power flow [7]. Conventionally, these DG resources are not integrated with each other and separately run the load, controlled by individual switches [8, 9, 10, 11, 12]. The power quality issues involved during the conversion from dc source to ac for Microgrid operation have become the subject of research. Moreover, the study of intelligent control for Microgrid is also in progress [13, 14, 15]. In this research paper, the single control unit is responsible for overall functioning of the developed model of Microgrid supported by the physical location of RCET Grw, Pk, where a Marala Nokhar Link Canal flows adjacent to the college. The complete simulation of Microgrid has been performed using MATLAB Simulink for supplying power to RCET library. 2. Geographical Location of RCET Fig. shows the geographical location of RCET indicating the renewable energy resources and library (load). Fig. 1.

Real Models of Renewable Energy Resources at RCET The project for Microgrid development at RCET is divided into two main phases: Firstly, modelling and simulation of Microgrid and secondly, implementation of simulated model practically. For this purpose, three real models have been focused at RCET. Fig. shows the practical Biomass arrangement to produce methane gas (CH4) used directly as input to Fuel Cell or the same methane gas can be decomposed to get hydrogen. In this research work hydrogen Fuel Cell is used for simulation purpose. Fig. 3. Biomass plant at RCET Fig. 4 is indicating the PV Array which is available at RCET for solar energy generation. [pic] Fig. 4. PV Array Fig. 5 is showing the Micro-hydro resource which will be utilized for generation of electricity through Microgrid while implementing the simulated model. [pic] Fig. 5. View of Nokhar Canal flowing adjacent to RCET 4. Block diagram of Proposed Microgrid Block diagram of proposed Microgrid is given in Fig. 6. Fig. 6. Block diagram of Microgrid PV Array and Fuel Cell are dc sources where the Micro-hydro is an ac source of power supply. So, for synchronization the both afore mentioned resources will also be converted in ac supply. Two methods are used to convert the dc sources into ac supply. First is the Pulse Width Modulator (PWM) inverter to convert dc supply into ac supply. The second method is the use of Motor-Generator set, in which dc motor is run by dc supply and then that motor will be used as prime mover for generator to provide ac output at the terminals of generator. Their results are also compared in this research work. Moreover, this combined generating unit of Microgrid is also integrated with National grid for both way flow of power. Whenever the generation exceeds the load requirement, the extra power will be supplied to distribution network of National grid, otherwise it will be supplied by National grid 5. Modelling and Simulation Comprehensive modelling and simulation of Microgrid to run 8 kW load of RCET Library has been performed using MATLAB software. The detail of mentioned software used for simulation is as under: MATLAB  ®, the Language of Technical Computing Version: 7. 6. . 324 (R 2008a), February 10, 2008 License Number: 161051 Fig. 7 shows the Interconnected Microgrid in which all the three renewable energy resources are connected to run the Library load. Moreover, this generating unit is further interconnected with Power distribution system (National Grid) for both way power supply. [pic] Fig. 7. Microgrid Simulation Model Br ief description of resources (PV Array, Fuel Cell and Micro-hydro) used in simulation is as under: 5. 1. PV Array For simulation purpose, PV Array is replaced with a 12 v dc battery, which is boosted up by use of DC/DC Boost Converter up to 320 v dc as shown in Fig. . [pic] Fig. 8. DC Battery DC/DC Boost Converter Fig. 9 is indicating the PWM operation, to convert 320 v dc supply into 400 v ac. [pic] Fig. 9. PV Array Simulation Model using PWM Inverter The above simulation is also performed using Motor-Generator set. Fig. 10 is the Simulink model for PV Array based ac supply generating unit in which Motor-Generator set is used for dc to ac conversion. Output of PV Array is 12 v dc which is boosted up to 240 v dc using DC/DC Boost Converter to run the dc motor. [pic] Fig. 10. PV Array Simulation Model using Motor-Generator Set 5. 2. Fuel Cell Fuel Cell is also dc generation source like PV Array. Here dc is again required to convert into ac supply for integration among the renewable energy resources and also with National grid. For this purpose both PWM Inverter technique as well as the Motor-generator set are used. Fig. 11 shows the hydrogen Fuel Cell in which dc supply is boosted up through DC/DC Boost Converter and after that the same mechanism of PV Array, as shown Fig. 9, is used to convert up to the required ac voltage level [pic] Fig. 11. Hydrogen Fuel Cell Fig. 12 shows the internal model of Motor-Generator set for dc to ac conversion used in Fuel cell. pic] Fig. 12. Fuel Cell Simulation using Motor-Generator set PWM inverter is commonly used for dc to ac conversion. However, Motor-Generator set has also been practiced during this research work. Due to certain inherited characteristics, like increase in technical losses, vibration at starting etc, PMW is preferred considering operational and economic comparison. 5. 3. Micro-hydro Micro-hydro is an ac source of power supply. For simulation purpose, Micro-hydro is replaced with a synchronous generator. Fig. 13 indicates the internal model of Micro-hydro. [pic] Fig. 13. Micro-hydro simulation structure 6. Comparison of PWM and Motor-Generator Set output In the following sections, comprehensive comparison of PWM and Motor-Generator set techniques is given graphically along with tabular form. This comparison reveals that the latter mechanism is suffering from unavoidable fluctuation initially, resulting in undue operational and economic constrains. Keeping in view the above scenario, PWM technique is more advantageous. 6. 1. PWM Inverter The results for PV Array obtained in result of simulation performed using Fig. 7 are given in Fig. 14. Fig. 14. PV Array output Vinv shows the 320 v ac PWM output. VLoad is the desired level of voltage that appears at the load terminals. PL is the Library load. During time interval (0–0. 4) sec, PV Array shares 2. 67 kW (out of 8 kW) of Library load and rest of the 3. 3 kW is supplied to National grid. From (0. 4–1. 0) sec PV Array is supplying total generating power (6 kW) to National Grid. The results for Fuel Cell got in result of simulation performed using Fig. 7 are given in Fig. 15. [pic] Fig. 15. Fuel Cell results During time interval (0–0. 4) sec Fuel Cell shares 2. 7 kW of Library load and supplies 3. 3 kW to National Grid. From (0. 4–0. 7) sec it shares 4 kW of Library load. From (0. 7–1. 0) sec it provides total generated power (6kW) to National Grid. Following the previous pattern, results regarding Micro-hydro are shown in Fig. 16. Fig. 16. Micro-hydro output During time interval (0–0. 4) sec Micro-hydro shares 2. 67 kW of Library load. From (0. 4–0. 7) sec it shares 4 kW and from (0. 7–1. 0) sec it provides all 6 kW to Library Load and reaming 2 kW are contributed from National Grid. The previous results are summarized in Table II: TABLE II Microgrid Power Flow using PWM Inverter |Time |PV Array (kW) |Fuel Cell (kW) |Micro-hydro ( kW) | |Interval | | | | | |PL |Psys |PL |Psys |PL |Psys | |(0–0. 4) sec|2. 67 |-3. 30 |2. 67 |-3. 30 |2. 67 |-3. 30 | |(0. 4 –0. 7) |0 |-6. 0 |4. 0 |-2. 0 |4. 0 |-2. 0 | |sec | | | | | | | |(0. 7 – 1. 0)|0 |-6. 0 |0 |-6. 0 |6. |2. 0 | |sec | | | | | | | 6. 2. Motor-Generator Set Simulation referring to Fig. 7 using dc Motor-Generator set in comparison with PWM inverter is described graphically in this section. Results are also summarized in tabular form. Figs. 17, 18 and 19 are the graphical results of PV Array, Fuel Cell and Micro-hydro respectively using Motor-Generator set for dc to ac conversion where required. Results discussed earlier indicate the initial fluctuation in case of Motor-Generator set is prominent. Fig. 17. PV Array output (Motor-Generator Set) [pic] Fig. 18. Fuel Cell output (Motor-Generator Set) [pic] Fig. 19. Micro-hydro output (Motor-Generator Set) The results are tabulated as under: TABLE III Microgrid Power Flow using Motor-Generator set |Time |PV Array (kW) |Fuel Cell (kW) |Micro-hydro ( kW) | |Interval | | | | | |PL |Psys |PL |Psys |PL |Psys | |(0–6. 5) |2. 67 |-3. 30 |2. 67 |-3. 3. 0 |2. 67 |-3. 3. | |sec | | | | | | | |(6. 5–14) |4. 0 |-2. 0 |4. 0 |-2. 0 |0 |-6. 0 | |sec | | | | | | | |(14–20) |0 |-6. 0 |6. 0 |2. 0 |0 |-6. 0 | |sec | | | | | | | 7. Islanding with National Grid To cope with the contingencies, islanding of the simulated Microgrid with National grid is shown in Figs. 20 and 21 respectively. [pic] Fig. 20. Islanding with National Grid pic] Fig. 21. Internal Structure of Fig. 20 It is clear from Fig. 21 that Microgrid is running 6 kW load. At time 0. 3 sec, 1. 5 kW is added with the system, and at 0. 5 sec another 2 kW is connected wit h the system and at 0. 7 sec additional 2. 5 kW load is connected with the system. Now total load connected to Microgrid (interconnected with National grid) is 12 kW, where 6 kW is shared by Microgrid while remaining 6 kW is supported by National Grid. Fig. 21 shows the results measured by scope in which at time interval 1 sec. the breaker of National Grid is open. The purpose behind this is to produce an artificial over current fault when all the 12 kW load is supposed to be shared by Microgrid, resulting in voltage drop at output terminals of Microgrid. During this operation, the over current and under voltage relays will be operated and consequently additional 6 kW load will be disconnected as indicated in Fig. 21(the position of breaker went to ‘0’ at time 1. 0 sec). [pic] Fig. 21. Islanding results The islanding operating is summarized in table IV as: TABLE IV Islanding operation |Time |Load Shared by|Load Shared by |Breaker |Total Load | Interval |Microgrid |National grid |Position | | |(sec) | | | | | |0 – 0. 3 |6. 0 kW |0 kW |ON (1) |6. 0 kW | |At 0. 3 |6. 0 kW |1. 5 kW |ON (1) |7. 5 kW | |At 0. 5 |6. 0 kW |3. 5 kW |ON (1) |9. 5 kW | |At 0. 7 |6. 0 kW |6 kW |ON (1) |12. 0 kW | |At 1. 0 |12. 0 kW |0 |OFF (0) |12. 0 kW | |1. 0 (Relay |6. 0 kW |0 |OFF (0) |6. kW | |operates) | | | | | 8. Conclusions This novel approach comprising of locally available renewable energy resources and integration of these resources for up-gradation to commercial use will really help the National Electric Power Regulatory Authority (NEPRA), Alternative Energy Development Board (AEDB) and Pakistan Electric Power Company (PEPCO) to set their directions while planning about generation of electricity from renewable energy resources to minimize huge gap between demand and supply. Comparing traditional and latest instrumental techniques is really interesting during this research work. Innovative model developed will also help the scientific community at national and international level. For further investigations like the influence of the factors influencing power quality issues is in progress. References [1] Robert H.
