Business Task 1 on individual report Essay

                 Despite its future economic prospects, the United Arab Emirates continues to suffer from corporate governance issues. The development of corporate governance in the region has largely been influenced by religion (Gellis et al., 2002). The rules governing the practice of corporate governance have been significantly influenced by Islamic Sharia. This reflects the cultural and religious characteristic of the region (Islam and Hussain, 2003). Islamic Sharia specifies a number of core values such as trust, integrity, honesty and justice which are similar to the core values of corporate governance codes in the West. However, a survey of corporate governance in a number of Gulf countries such as United Arab Emirates suggests that the region continues to suffer from corporate governance weaknesses. 2.0 Reasons for the structure including use of suitable evidence and data                  The structure of the above sectors and reasons for the structure and effects on the performance of firms has been vital subject of debate in the finance literature. Empirical evidence suggests that privately held firms tend to be more efficient and more profitable than publicly held firms. This shows that ownership structure matters. The question now is how does it affect firm performance and why this kind of structure? This question is significant since it is based on a research agenda that has been strongly promoted by La Porta et al.                  According to these studies, failure of the legislative framework to provide sufficient protection for external investors, entrepreneurs and founding investors of a company tend will maintain large positions in their firms thus resulting in a concentrated ownership structure. This finding is interesting because it implies that ownership structure can affect the performance of the firm in one way or the other. It is indisputable; the lack of regulations in corporate governance gives managers who intend to mishandle the flow of cash for their own personal interest a low control level. The empirical results from the past studies of impacts of ownership structure on performance of corporate have been inconclusive and mixed up.               In response to corporate governance issues and their impact on corporate performance, Shleifer and Vishny (1997); and Jensen (2000) have suggested the need for improved corporate governance structures so as to enhance transparency, accountability and responsibility.                  Corporate governance reform and the introduction of innovative methods to limit abuse of power by top management have been justified by recent large scale accounting and corporate failures such as Enron, HealthSouth, Tyco International, Adelphia, Global Crossing, WorldCom, Cendant and the recent global financial crisis.                   According to Monks and Minow (1996) numerous corporate failures suggest that existing corporate governance structures are not working effectively. Corporate failures and accounting scandals initially appear to a U.S phenomenon, resulting from excessive greed by investors, overheated equity markets, and a winner-take-all mind-set of the U.S society. However, the last decade has shown that irregularities in accounting, managerial greed, abuse of power, are global phenomenon that cannot be limited to the U.S. Many non-U.S firms such as Parallax, Adecco, TV Azteca, Hollinger, Royal Dutch Shell, Vivendi, China Aviation, Barings Bank, etc. have witnessed failures in corporate governance and other forms of corporate mishaps.            In addition to corporate governance failures, global standards have declined significantly and unethical and questionable practices have become widely accepted. The net impact has been a reduction in the amount of faith that investors and shareholders have in the efficiency of capital markets. There is no universally accepted corporate governance model that the interest of shareholders and investors are adequately protected as well as ensuring that enough shareholder wealth is being created (Donaldson and Davis, 2001; Huse, 1995; Frentrop, 2003).               Much of the debate on corporate governance has focused on understanding whether the Board of Directors has enough power to ensure that top management is making the right decision. The traditional corporate governance framework often ignores the unique effect that the owners of the firm can have on the board and thus the firm’s top management. The traditional framework therefore ignores that fact that the owners of the firm can influence the board and thus top management to act of make particular decisions. Corporate governance studies are therefore yet to identify and deal with the complexities that are inherent in corporate governance processes.             Investment choices and owner preferences are affected among other things by the extent their degree of risk aversion. Owners who have economic relations with the firm will be interested in protecting their interests even if it is reasonably evident that such protection will result in poor performance. According to Thomsen and Pedersen (1997) banks that play a dual role as owners and lenders would discourage high risk projects with great profit potential because such projects may hinder the firm from meeting its financial obligations if the project fails to realize its expected cash flows. The government also plays a dual role in that it serves as both an owner and a regulator. Therefore owners who play a dual role in the firm often face a trade-off between promoting the creation of shareholder value and meeting their other specific objectives (Hill and Jones, 1992).                  Existing corporate governance frameworks have often ignored these issues in UAE. Rather, much of the emphasis has been on the effectiveness of the board in ensuring that top management is working towards meeting the goals of shareholders. Present corporate governance frameworks lack the ability to monitor owners and their influence on top management. The framework lacks the ability to align the role played by firm owners, board of directors and managers’ interests and actions with the creation of shareholder value and welfare motivation of stakeholders. Discussion of the possible future structure of the industry                     The United Arabs Emirates, and mainly Abu Dhabi, is enduring to increase its economy by reducing the total proportion impact of hydrocarbons to Gross Domestic Product. This is currently being done by growing investment in sector areas like: services in telecommunication, education, media, healthcare, tourism, aviation, metals, petrochemicals, pharmaceuticals, biotechnology, transportation and trade.                   Significant investments have been made by United Arab Emirates to establish itself as a regional trade hub. United Arab Emirates is also member of the World Trade Organization (WTO). In addition, there are ongoing negotiations to establish free trade agreements with other regions and countries such as the EU. These factors will contribute positively to the region’s integration into the global economy. United Arab Emirates is currently working towards diversifying their economies from the oil sector into other sectors. This diversification is expected not only to increase trade among member countries but also to increase the region’s trade with other countries and regions (Sturm et al., 2008). How the structure affects strategy decisions                     Ownership structure has an impact on firm performance in United Arab Emirates energy production owned sector. This region has witnessed significant economic growth over the last few decades. The region is also facing turbulent times with respect to corporate governance practices, resulting in poor firm performance. Corporate governance issues are not limited to the United Arabs Emirates as part of GCC Countries. From a global point of view, corporate governance has witnessed significant transformations over the last decade (Gomez and Korine, 2005). As a result, there has been an interest in the research attention accorded to corporate governance. The credibility of current corporate governance structures has come under scrutiny owing to recent corporate failures and low corporate performance across the world.                   The risk aversion of the firm can be directly affected by the ownership structure in place. Agency problems occur as a result of divergence in interests between principals (owners) and agents (managers) (Leech and Leahy, 1991). The board of directors is thereby regarded as an intermediary between managers and owners. The board of directors plays four important roles in the firm. These include monitoring, stewardship, monitoring and reporting. The board of directors monitors and controls the discretion of top management. The board of directors influences managerial discretion in two ways: internal influences which are imposed by the board and external influences which relate to the role played by the market in monitoring and sanctioning managers.                                       B: Contribution of the sector to the economy of your chosen country                         Analysis of contribution of sector                  United Arab Emirates remain major global economic player because it has the highest oil reserves. UAE together with the other Gulf Cooperation Council accounts for over 40% of global oil reserves and remains important in supplying the global economy with oil in future. As a result, investment spending on oil exploration and development of new oil fields is on the rise.                   Global oil demand is currently on the rise. This growth is driven mainly by emerging market economies, as well as the oil producing UAE as part of GCC countries. In addition, Europe and the U.S are witnessing depletions in their oil reserves. This means that these regions will become increasingly dependent on the Gulf region which includes UAE for the supply of oil (Sturm et al., 2008). The importance of the United Arabs Emirates as a global economic player is therefore expected to increase dramatically in the near future Use of appropriate data and other evidence                By the year 2011, the GDP of United Arab Emirates totaled to 360.2 billion dollars. Subsequently in 2001, yearly growth of GNP varied from about 7.4% to 30.7%. As part of the chief crude oil suppliers, the United Arab Emirates was at first cut off from the universal recession by high prices on oil that rose to a record 147 US dollars per barrel in the month of July in 2008. Nevertheless, the nation was ultimately influenced by the excavating worldwide recession which resulted to a decline in oil demand, reducing the oil prices to a reduced amount not exceeding a third of the peak of July 2008. In the last 2008 months, the trembles rumbling through global economies were lastly experienced in this section. Oil (million barrels) Proved reserves, 2013 Total oil supply (thousand bbl/d), 2012 Total petroleum consumption, 2012 Reserves-to-production ratio 97,800 3,213 618 95 Natural Gas (billion cubic feet) Proved reserves, 2013 Dry natural gas production, 2012 Dry natural gas consumption, 2012 Reserves-to-production ratio 215,025 1,854 2,235 116 UAE summary energy statistics C: Critical appraisal of sustainability targets on business plan of your chosen organisation                   Oil firms in United Arab Emirates is still quite immature. Most businesses are controlled by a few shareholders and family ownership is prevalent. Most large and small businesses are family businesses (Saidi, 2004). The state is also significantly involved in the management of companies (Union of Arab Banks, 2003).                     This is contrary to the status quo in Western democracies where firms are owned by a diverse group of shareholders which makes ownership to be completely separated from control. The ownership structure in United Arab Emirates suggests that stewardship and monitoring aspects of non-executive directors (NEDs) is absent in firms based in United Arab Emirates. Ownership concentration has remained high in the region because of practices such as rights issues which enable existing wealthy shareholders, and influential families to subscribe to new shares in Initial Public Offerings (IPOs) (Musa, 2002).                   According to a study of the corporate governance practices of five countries by the Union of Arab Banks (2003), ownership of corporations is concentrated in the hands of families. In addition, corporate boards are dominated by controlling shareholders, their relatives and friends (Union of Arab Banks, 2003). There is a no clear separation between control and ownership. Decision making is dominated by shareholders. The number of independent directors in the board is very small and the functions of the CEO and Chairman are carried out by the same person. The high concentration in firm ownership therefore undermines the principles of good corporate governance that are prevalent in western settings (Yasin and Shehab, 2004). This evidence is consistent with findings by the World Bank (2003) in an investigation of corporate governance practices in the Middle East North Africa (MENA) region which also includes the Gulf region. 1.0 Objective of empirical evidence                   The empirical evidence on the impact of ownership structure on firm performance is mixed. Different studies have made use of different samples to arrive at different, contradictory and sometimes difficult to compare conclusions. The literature suggests that there are two main ownership structures in firm including dispersed ownership and concentrated ownership. With respect to concentrated ownership, most of the empirical evidence suggests that concentrated ownership negatively affects performance (e.g., Johnson et al., 2000; Gugler and Weigand, 2003; Grosfeld, 2006; Holmstrom and Tirole, 1993). Different studies have also focused on how specifically concentrated ownership structures affect firm performance. For example, with respect to government ownership, Jefferson (1998), Stiglitz (1996), and Sun et al. (2002) provide theoretical arguments that government ownership is likely to positively affect firm performance because government ownership can facil itate the resolution of issues regarding the ambiguous property rights.                   However, Xu and Wang (1999) and Sun and Tong (2003) provide empirical evidence that government ownership has a negative impact on firm performance. On the contrary, Sun et al. (2002) provide empirical evidence that government ownership has a positive impact on firm performance. It has also been argued that the relationship between government ownership and firm performance is non-linear. Another commonly investigated ownership type and its impact on firm performance is family ownership. Anderson and Reeb (2003), Villanonga and Amit (2006), Maury (2006), Barontini and Caprio (2006), and Pindado et al. (2008) suggest that there is a positive link between family ownership and firm performance. Despite the positive impact some studies argue that the impact of family ownership is negative (e.g. DeAngelo and DeAngelo, 2000; Fan and Wong, 2002; Schulze et al., 2001; Demsetz, 1983; Fama and Jensen, 1983; Shleifer and Vishny, 1997).                     The impact of foreign ownership has also been investigated. Most of the evidence suggests that foreign ownership has a positive impact on firm performance (e.g., Arnold and Javorcik, 2005; Petkova, 2008; Girma, 2005; Girma and Georg, 2006; Girma et al., 2007; Chari et al., 2011; Mattes, 2008).With respect to managerial ownership, it has been argued that the relationship is likely to be positive. Despite this suggestion Demsetz and Lehn (1985) observe a negative relationship between dispersed ownership and firm performance. Institutional ownership has also been found to have a positive impact on firm performance (e.g. McConnell and Servaes, 1990; Han and Suk, 1998; Tsai and Gu, 2007). Furthermore, some studies suggest that there is no link between insider ownership and performance.                  Very limited studies have been conducted on the impact of ownership structure on firm performance in GCC countries like UAE. For example, Arouri et al. (2013) provide evidence that bank performance is affected by family ownership, foreign ownership and institutional ownership and that there is no significant impact of government ownership on bank performance. Zeitun and Al-Kawari (2012) observe a significant positive impact of government ownership on firm performance in the Gulf region.                The pervasive endogeneity of ownership has been cited as a potential reason why it is difficult to disentangle the relationship between ownership structure and firm performance. In addition, the relation may be a function of the type of firm as well as the period of observation in the life of the firm. This study is motivated by the mixed results obtained in previous studies and the limited number of studies that have focused on UAE as part of GCC countries. The objective of the study is to explore in more details the factors that motivate particular types of ownership structure and the potential impact of ownership structure and firm performance in the Gulf region 2.0 Empirical Evidence                  The empirical evidence will focus on how different ownership structures affect firm performance. Firms are often characterized by concentrated and dispersed ownership. Concentrated ownership is expected to have a positive impact on firm performance owning to the increased monitoring that it provides.                Dispersed ownership has been found to be less frequent than expected. Empirical evidence suggests that most firms are characterized by various forms of ownership concentration. Given this high level of ownership concentration, there has been an increasing concern over the protection of the rights of non-controlling shareholders (Johnson et al., 2000; Gugler and Weigand, 2003). Empirical evidence shows that ownership concentration at best results in poor performance. Concentrated ownership is costly and has the potential of promoting the exploitation of non-controlling shareholders by controlling shareholders (Grosfeld, 2006). Holmstrom and Tirole (1993) argue that concentrated ownership can contribute to poor liquidity, which can in turn negatively affect performance. In addition, high ownership concentration limits the ability of the firm to diversify (Demsetz and Lehn, 1985; Admati et al., 1994). There are various forms of concentrated ownership such as gov ernment ownership, family ownership, managerial ownership, institutional ownership and foreign ownership. In the next section, the literature review will focus on how these separate ownership structures affect firm performance. 2.1.1 Government Ownership                     The impact of government ownership on firm performance has attracted the attention of many researchers because the government accounts for the largest proportion of shares of listed companies in some countries and also because government ownership can be used as an instrument of intervention by the government (Kang and Kim, 2012). Shleifer and Vishny (1997) suggest that government ownership can contribute to poor firm performance because Government Owned enterprises often face political pressure for excessive employment. In addition, it is often difficult to monitor managers of government owned enterprises and there is often a lack of interest in carrying out business process reengineering (Shleifer and Vishny, 1996; Kang and Kim, 2012). Contrary to Shleifer and Vishny (1997) some economists have argued that government ownership can improve firm performance in less developed and emerging economies in particular. This is because government ownership c an facilitate the resolution of issues with respect to ambiguous property rights.                   The empirical evidence on the impact of state ownership on firm performance is mixed. For example, Xu and Wang (1999) provide evidence of a negative relationship between state ownership and firm performance based on data for Chinese listed firms over the period 1993-1995. The study, however, fails to find any link between the market-to-book ratio and state ownership (Xu and Wang, 1999). Sun and Tong (2003) employ ownership data from 1994 to 2000 and compares legal person ownership with government ownership. The study provides evidence that government ownership negatively affects firm performance while legal person ownership positively affects firm performance. This conclusion is based on the market-to-book ratio as the measure of firm performance.                   However, using return on sales or gross earnings as the measure of firm performance, the study provides evidence that government ownership has no effect on firm performance. Sun et al. (2002) provide contrary evidence from above. Using data over the period 1994-1997, Sun et al. (2002) provide evidence that both legal person ownership and government ownership had a positive effect on firm performance. They explain their results by suggesting that legal person ownership is another form of government ownership. The above studies treat the relationship between government ownership and firm performance as linear. However it has been argued that the relationship is not linear.                  Huang and Xiao (2012) provide evidence that government ownership has a negative net effect on performance in transition economies. La Porta et al. (2002) provide evidence across 92 countries that government ownership of banks contributes negatively to bank performance. The evidence is consistent with Dinc (2005) and Brown and Dinc (2005) who investigate government ownership banks in the U.S. 2.1.2 Family Ownership                  Family ownership is very common in oil firms in UAE. There is a difference between family ownership and other types of shareholders in that family owners tend to be more interested in the long-term survival of the firm than other types of shareholders(Arosa et al., 2010).. Furthermore, family owners tend to be more concerned about the firm’s reputation of the firm than other shareholders (Arosa et al., 2010). This is because damage to the firm’s reputation can also result in damage the family’s reputation. Many studies have investigated the relationship between family ownership and firm performance. They provide evidence of a positive relationship between family ownership and firm performance (e.g. Anderson and Reeb, 2003; Villalonga and Amit, 2006; Maury, 2006; Barontini and Caprio, 2006; Pindado et al., 2008).                   The positive relationship between family ownership and firm performance can be attributed to a number of factors. For example, Arosa et al. (2010) suggests that family firms’ long-term goals indicate that this category of firms desire investing over long horizons than other shareholders. In addition, because there is a significant relationship between the wealth of the family and the value of the family firm, family owners tend to have greater incentives to monitor managers (agents) than other shareholders (Anderson and Reeb, 2003). Furthermore, family owners would be more interested in offering incentives to managers that will make them loyal to the firm.                     In addition, there is a substantial long-term presence of families in family firms with strong intentions to preserve the name of the family. These family members are therefore more likely to forego short-term financial rewards so as to enable future generations take over the business and protect the family’s reputation (Wang, 2006). In addition, family ownership has positive economic consequences on the business. There are strong control structures that can motivate family members to communicate effectively with other shareholders and creditors using higher quality financial reporting with the resulting effect being a reduction in the cost of financing the business.                Furthermore, families are interested in the long-term survival of the firm and family, which reduces the opportunistic behavior of family members with regard to the distribution of earnings and allocation of management,.                   Despite the positive impact of family ownership on firm performance, it has been argued that family ownership promotes high ownership concentration, which in turn creates corporate governance problems. In addition, high ownership concentration results in other types of costs. As earlier mentioned, La Porta et al. (1999) and Vollalonga and Amit (2006) argue that controlling shareholders are likely to undertake activities that will give them gain unfair advantage over non-controlling shareholders. For example, family firms may be unwilling to pay dividends .                  Another reason why family ownership can have a negative impact on firm performance is that controlling family shareholders can easily favour their own interests at the expense of non-controlling shareholders by running the company as a family employment service. Under such circumstances, management positions will be limited to family members and extraordinary dividends will be paid to family shareholders. Agency costs may arise because of dividend payments and management entrenchment. Families may also have their own interests and concerns that may not be in line with the concerns and interests of other investor groups.                Schulze et al. (2001) provide a discussion, which suggests that the impact of family ownership on firm performance can be a function of the generation. For example, noting that agency costs often arise as a result of the separation of ownership from control, they argue that first generation family firms tend to have limited agency problems because the management and supervision decisions are made by the same individual. As such agency costs are reduced because the separation of ownership and control has been completely eliminated. Given that there is no separation of ownership and control in the first generation family firm, the firm relationship between family ownership and performance is likely to be positive (Miller and Le-Breton-Miller, 2006). As the firm enters second and third generations, the family property becomes shared by an increasingly large number of family members with diverse interests. The moment conflict of interests sets in the relationship between family ownership and performance turns negative in accordance to. Furthermore, agency problems arise from family relations because family members with control over the firm’s resources are more likely to be generous to their children and other relatives.                To summarize, the relationship between family ownership and firm performance may be non-linear. This means that the relationship is likely to be positive and negative at the same time. To support this contention, a number of studies have observed a non-linear relationship between family ownership and firm performance (e.g. Anderson and Reeb, 2003; Maury, 2006). This means that when ownership is less concentrated, family ownership is likely to have a positive impact on firm performance. As the family ownership concentration increases, minority shareholders tend to be exploited by family owners and thus the impact of family ownership on firm performance tends negative.                  Small countries have a relatively weak diamond of competitive advantages. D. Analysis 1.0 Potter’s Diamond Model                  The competitive forces advantages or analysis ought to be fixed on the main competition factors and its impact analysis on the business (Porter 1998, p.142).

Threats Expansion of oil production capacity of economies of South-Eastern that have competed with low prices of products and little costs of production. Loan jobs and production globalisation. Reinforcement of local competition of adjacent economies, and thus reinforcing actions that attract direct overseas exploitation of the oil sector in UAE through investments.

Blood Collection Monitor

————————————————- Abstract: Blood Collection Monitor  is helpful for accurate blood collection; it’s a compact instrument to provide smooth and gentle rocking of homogenous mixing with anti coagulant ; i. e. without clot formation of blood cells during collection of blood from a donor. BLOOD COLLECTION PROCESS IS HAPPENING IN DIFFERENT ENVIRONMENTS. THE CHALLENGE TO PHLEBOTOMIST (One who draws blood for analysis or transfusion) IS TO MAKE EACH BLOOD COLLECTION PROCESS COMFORTABLE AND SAFE WITHOUT COMPROMISING QUALITY.BLOOD COLLECTION MONITOR COMES INTO ROLE HERE; IT IS SPECIALLY DESIGNED TO MAKE STANDARDIZED HIGH QUALITY BLOOD COLLECTION WITH REDUCED WORK LOAD OF PHLEBOTOMIST. BLOOD COLLECTION MONITOR ENSURES CORRECT VOLUME OF BLOOD COLLECTION WITH CONSTANT AGITATION FOR BETTER COMPONENT YIELD. SO, THE CORRECT VOLUME OF BLOOD COLLECTION AND MIXING OF THE BLOOD AND ANTICOGULANT GENTLY AND PERIODICALLY DURING COLLECTION OF BLOOD; CAN BE DONE BY BLOOD COLLECTION MONITOR. 1. ————————————————- Introduction: BLOOD COLLECTION MONITOR is an advanced device which is aimed to collect the blood prior to collection with use of latest technology in place of earlier, insufficient, conventional methods i. e. without accurate weight by using random movement. The main concept behind this project is use of mechanically provide rocking movement to blood and proper mixing with anticoagulants. Also restrict the blood flow from donor when particular limit is reached. I. e. 350ml or 450ml. This is done by load cell and by comparing signal activate the stopping clamp is activated.As, sensing range of load cell is in mill volts; directly the signal can be given as input to the circuit because it will provide insufficient output. So, it is required to be pro perly amplified. So, the block diagram is designed taking into account this matter. Then comparing it with reference signal which is decided by many experiments. It activates the clamp and stops the rocking movement of plate when weight in blood bag is presented. It is approximate to the actual design but more function of the instrument by extra features like flow detector, flow rate measurement etc.So, the component specifications may differ from the actual one. fig 1. blood bag fig 2. blood bag on plate of bcm 2. ————————————————- Requirement of project: As we all know that blood collection monitor is very helpful for collection of accurate blood, it’s a compact instrument that provide smooth and gentle rocking movement of homogeneous mixing with anti-coagulant, so in modern lifestyle most of the doctors prefer these types of instrument for collection of blood ver y accurately. Blood collection monitor is very helpful to donate blood. hat happen in past that there’s no such types of instruments were present so it is inaccurate random process for doctors to take blood from the donor and also sometimes improper mixing with anti coagulant lead to waste the valuable donated blood that process may not helpful to accurately blood collection. With the help of this modern instrument it is very easy for doctors to take the blood from the donor, and through this instrument may also required less effort. Collection of blood accurately and safely. 3. ————————————————- Generalized block diagram AND CIRCUIT DIAGRAM:BLOCK DIAGRAME OFComparator CIRCUIT 5-PIN RELAY DC MOTOR CLAMP MOMENT (OPEN/CLOSE) Blood Collection Monitor POWER SUPPLY AC MAINS INSTRUMENTATION AMPLIFIER CIRCUIT WEIGHT MEASUREMENT UNITS/LOAD CELL DC MOTOR rocking MOMENT OF TR AY BLOOD Donor/BLOOD BAG CIRCUIT DIAGRAME OF Blood Collection Monitor 5-PIN RELAY Each block in briefly†¦Ã¢â‚¬ ¦ 1.

POWER SUPPLY: This is the main block in any of the electronic as well as biomedical project. Its Main function is to provide electrical excitation. 5. 2. 1. COMPONENTS USED: * IC 7812, 79 12(+12V,-12 V) * IC 7805, 7905(+5V,-5V) * IC 7815, 7915(+15V,-15V) * diode for bridge rectifier (4) capacitors of 1000 micro farads, 50 volts (2) * capacitors of 0. 1 micro farads (2*4) * center tapped transformer 18-0-18 5. 2. 2. CIRCUIT DIAGRAM: FIG 3. CIRCUIT DIAGRAM OF DC POWER SUPPLY (+/-5,+/-12,+/-15 V dc) 5. 2. 3. WORKING OF CIRCUIT: The working of this circuit is so simple . Mains supply is given to the 12-0-12 center-tapped transformer. Output of secondary winding is given to the bridge rectifier IC . Then to get peak-to-peak output voltage signal, capacitors are used. In lab-application, variable power supplies are preferred. 4. 2. ROCKING movement of plate and weight sensor:Whole assembly made such that one side of plate is joined with DC motor and U shaped bended rod which can able to push and pull plate from one side as plate is fixed with assembly from center power to DC motor lead rocking or sea show type movement which we want. It is most important part of instrument as mixing blood with anticoagulant properly. Fig 5. DC motor shaft connected to assembly. Fig 4. assembly to provide rocking movement. Sensing weight of blood bag during donating the blood it is most important task as on this basis measuring, displaying, and further stopping of blood flow mechanism works.To measure the blood weight we used load cell as a sensor. In load cell according to change in weight input output in mill volt also changes by using this basic principle weight sensing is done. Load cell has in built bridge balancing circuit with weight sensor. Fig 8. Cantilever beam connection. Fig 7. load cell. Fig 6. Internal circuit of load cell. Fig 9. Original data sheet by Rudra sensors. According to data sheet input 8-12dc volt given to cell and output in changes in millivoltags. Below is data sheet of load cell. 4. 2. 1. COMPONENTS USED: * 12 volt DC motor Wooden and iron assembly * Plate * 12 volt dc supply 4. 3. INSTRUMENTATION AMPLIFIER: This block provides sensor outp ut signal the sufficient amplification so as to drive further circuits properly and without loading. Generally 3 Op-Amp instrumentation amplifiers are employed in biomedical projects. As load cell senses in range of mill volts, we have to amplify it in of 1000 gain. Instrumentation amplifiers are actually made up of 2 parts: a buffered amplifier OP1, OP2 and a basic differential amplifier OP3. The differential amplifier part is often essential when measuring sensors.Because a sensor produces a signal between its terminals. The buffered amplifier OP1 and OP2 not only provides gain, but prevents the sensor resistance from affecting the resistors in the op amp circuit, and vice-versa! The gain can be calculated by: Where; R1=R3 and R5/R4 = R7/R6. (R5=RF). * Gain calculations: Gain (A) = (1+ (2*(R1/R2))*(RF/R4) Taking A=1000 & diving 1000 as 500*2, 1+2R1/R2=2 2R1/R2=1 2R1=R2 Taking R2=2K, R1 =1K. Now, RF/R4=500K R4=1K, RF=500K =1MOhm || 1MOhm = (1000000*1000000)/ (1000000+1000000) =500 K. 4. 3. 1. COMPONENTS USED: * IC OP07(3) Resistors of 1K (4 no’s) * Resistors of 2K (2 no’s) * Resistors of 1Mohm (2 no’s) * Power supply of 12 Vdc 4. 3. 2. CIRCUIT DIAGRAM: FIG. 10 CIRCUIT DIAGRAM OF INSTRUMENTATION AMPLIFIER 4. 3. 3. WORKING OF CIRCUIT: The instrumentation amp offers two useful functions: amplify the difference between inputs and reject the signal that’s common to the inputs. The latter is called Common Mode Rejection (CMR). OP1 and OP2 are the two input amp’s and connected in the non-inverting follower configuration. It is the solution for the high gain and high input impedance.Note: This is of high gain circuit so before soldering it on GPB, connectivity check of all the components as per circuit diagram twice on bread-board is advisable. There may chances of unpredictable o/p due to IC saturation. 4. 4. COMPERATOR: It compares the input signal with reference signal. When input exceed from reference signal it gives positive sa turation and negative saturation when less than reference signal. We are using 1 volt as a reference , as from experiment we get 1 volt output from instrument amplifier through load cell under 350ml blood beg. 4. 4. 1. Components used: 1 operational amplifier Op07 * Resistor 10k (3 no’s) * Protecting diodes (2 no’s) 4. 4. 2. CIRCUIT DIAGRAM: FIG 11. CIRCUIT DIAGRAM OF COMPERATOR BY USING IC OP07 4. 5 relay: Fig. 12 Basic relay construction A  relay  is an  electrically  operated  switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.Here in our applications operation is must switched from rocking movement to clamp operation. (As comparator detects particular weight i n plate rocking movements stops and clamp activated. ) Fig13. Pin diagram of 5pin relay 4. 5. 1. COMPONENT USED: * 5 PIN simple relay 4. 6. Stopping clamp: IV set passing from clamp that restrict the blood flow from donor. Fig 14. Clamp for restrict the blood flow When comparator generates stopping pulse from 5 pin relay it gives supply to DC motor and on its shaft rotation thread connected with clamp is going to pull and clamp is closed. Indicate that blood collection is completed.Also disconnect supply from DC motor that leads stop rocking movement. Fig 15. In our project IV set passing through clamp. In real instrument this type mechanism done by clamp type electromagnet as shown in figure. That pulsed by controller and as magnet generate the clamp force fully attract and it restrict the further blood flow from donor. 4. 6. 1. COMPONENTS FOR CLAMP MECHANISM: 12volt dc motor Plastic clip, Thread, Rubber bend 5. ————————â€⠀Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€- Application of project: The application of blood collection monitor is very widely used in blood bank and also in hospitals.Now a day’s almost all hospital’s doctor prefer these instrument for accurate collection of blood. Through this instrument we can easily collect the blood of donor and this instrument is also helpful in mixing the blood with anticoagulant so blood does not clot and also to collect the accurate amount of blood. Also indicate flow rate from donor to bag and error in flow rate whether any obstruction in donor vein in any case. Doctors and blood bank technicians prefer this instrument for the accurate collection of blood so we can say that its main application is in medical field and in hospitals. 6. ———————————————— Limitation: Blood collection monitor is a useful instrument for do ctors and so accurate for collection of blood so we found no any limitation in blood collection monitor right now. But ours is designed for only 350ml blood collecting, as well as it has no any current weight display, flow indications. Ours angular rocking movement is slightly large and jerky. 7. ————————————————- FUTURE EXPANSIONS: * In future this instrument will be facilities with more necessary parameters like flow rate, blood temp. Detector etc. Though motor used to rotate the plate not generating much noise but it will be removed in future. * Now a day’s BCM is single unit but in future it may facilities with some storage space of bag. (that will be more useful in mobile blood bank) * In future whole assembly make by fiber that’s making instrument lighter than present model. 8. —————————â₠¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€- CONCLUSION: For Blood collection monitor we can say that it is useful instrument for collection of blood accurately for doctors and safe for donors. And that’s why it’s being more commonly used in most hospitals now a day.From my side I conclude that to design a single unit of instrument is not possible without fundamental knowledge of electronics, controlling, basic of simple principles and last but not the least patience and faith in my work and strength. I also mention that repetitive work on any circuit remove basic doughty and also working problem. My project also teaches me the technical thoughts, human relationship. 9. ————————————————- References: * Books/manual/ Catalog:- * Manual of blood collection monitor of bioastate pvt.

The Internet Bubble Research Paper Example | Topics and Well Written Essays - 750 words

The Internet Bubble - Research Paper Example During this period, investors believed that a new era had begun with the internet sector seeing a 1000% growth in only two years, which equaled nearly 6% of the US’ market capitalization and more than 20% of equity volume traded publicly in the US. The bubble hit its peak in early 2000 with a score of 5,048.62 on NASDAQ (Kraay & Ventura, 2011). During this period, the sector saw increased establishment of internet companies that were referred to as Dotcom companies, taken from the suffix at the end of their URL. This bubble burst between the years 2000 and 2002 as NASDAQ saw a loss in value of over 80% with companies, for instance Pets.com, failing completely with more than $7 trillion destroyed in market value (Kraay & Ventura, 2011). This paper seeks to detail what happened during this period, why it transpired, the way it could have been prevented, as well as the main players in the internet bubble.The internet was responsible for creating a euphoric attitude in the 90s, in spiring hopes for the internet as online commerce’s future. This led to the formation of many dotcom companies hoping that they would be worth millions. However, most of these companies were not very successful as those that were overvalued (Perkins & Perkins, 2009). This resulted in these companies crashing, leaving significant losses to be handled by the investors. The collapse, in fact, precipitated the stock market crash of 2001 more than 9/11 did, costing investors $5 trillion. The mid to late 90s saw unrealistic expectations from the public regarding what the internet had to offer. Internet entrepreneurs invested in the hope of becoming internet billionaires, inspiring companies like Kozmo, eBay, and Amazon. However, for every internet company that became a success, hundreds of others collapsed. Most investors ignored fundamental rules of the stock market such as the analysis of P/E ratio, reviewing business plans, and the study of market plans (Perkins & Perkins, 2009) . They, instead, became pre-occupied with ideas that had no proven potential in the market. Factors that Led to the Internet Bubble Burst Two basic factors contributed to this phenomenon. The first was the utilization of metrics that were ignorant of cash flow. Most analysts laid emphasis on aspects of individual entrepreneurship that were not concerned with how to generate cash flow or revenue. One theory contends that the bubble burst due to the investors’ pre-occupation with what was referred to as the network theory, which stated that a network’s value increased exponentially. In addition, the number of nodes increased (Adams, 2009). While this made sense, it neglected the company’s ability utilizing the network for cash generation and making the investors a profit. Secondly, most of the internet company stocks were overvalued. On top of focusing metrics that were unnecessary, analysts made use of high multipliers in formulas and models in the valuation of t he companies, resulting in overly optimistic and unrealistic values (Adams, 2009). While the conservative analysts were not in agreement, the recommendations they made were

Who is jack the ripper Research Paper Example | Topics and Well Written Essays - 2250 words

Who is jack the ripper - Research Paper Example This fear was further aggravated due to social and economic conditions of the-then London. With over two hundred individual considered as suspects, this serial murderer mystery remained unresolved even after a century which has given it an outlook of most fearful murders of all times. The murders begin in 1888 in East London which was flooded with Jews and Russian migrants trying hard to make a better living. The place was even a hub of many brothels and sex-rental houses, where reaching a woman was not an issue. Murders of prostitutes and sex-servers was not an astonishing news for many at that time since these prostitutes were at the mercy of clients, owners of the brothels and even the gangsters. Constant tortures, physical attacks, and murders were part and parcel of prostitution industry. Even discussing these subjects was considered inappropriate in the civilized part of London. However, a wave of fear captivated London where a similar pattern accompanied by threatening and rather mocking letters was identified by London Police and Scotland Yard. These methods of conducting murders bear striking resemblance giving it a profile of serial killing and the letters received further assured that there is a murderer in town, with notorious intentions for women. Although Jack the Ripper only committed five murders which only lasted for three months, the question arises what makes him stand out when the history is full of serial killers with much brutal methods of murdering. Careful analysis would reveal that there are various elements that added to the mystery and made it eternal.

Dreamers versus Workers and Their Humanity Essay

Dreamers versus Workers and Their Humanity - Essay Example The Cherry Orchard illustrates Chekhov's time, when feudalism shifted to capitalism and how it differentiated the dreamers from the workers, although Chekhov did not press judgment on these people, since he also believes that humanity is humanity because they are fraught with weaknesses. Chekhov's time represented the transition from feudalism to capitalism in Russia, which drastically altered the social class structure and contributed to the â€Å"defeat of the cultured elite†. He shows Madame Ranevskaya’s household as the â€Å"passing of the semifeudal existence of Russian landowners on their country estates†. Madame Ranevskaya composes the aging and fading Russian aristocracy, who slips into economic decline after centuries of upholding luxurious lifestyles. Another class emerges, nevertheless, the â€Å"semiliterate, ambitious middle class† that Lopakhin belongs to. Lopakhin has become wealthy because of his hard work, which the aristocrats lacked. He is part of the â€Å"workers† in the play. Lopakhin feels short of being part of the true, new upper class, however. He realises that he can never replace the upper class: â€Å"...you'll find I'm still a peasant down to the marrow of my bones† (Chekhov Act 1). This viewpoint may also be part of Chekhov's belief that the bourgeoisie is a class of its own that cannot fully usurp the ancient charm and sophistication of the former aristocracy. The characters depict Chekhov's idea that dreams are nothing without action. Madame Ranevskaya lives in the same dream that she is still wealthy. She sells her villa to have her daughter Anya go to Paris. Once there, they act as if they remain rich. Anya tells Varya: â€Å"We had dinner at a station; she asked for all the expensive things, and tipped the waiters one rouble each† (Chekhov 1). Instead of living within their means, Madame Ranevskaya continues her former wealthy lifestyle, which economically ruins her. Madame Ra nevskaya also wants to save the orchard from being sold and divided. She is emotionally attached to the orchard, which is why she cannot bear selling it. The cherry trees stood for their aristocrat â€Å"happiness,† a happiness which Chekhov felt when he tended to his own orchard (Vorob'eva 82). Madame Ranevskaya knows that they cannot rely on Gaev, because he is also a dreamer who does act to save the orchard. He wants to save the orchard though, because it stands for their erstwhile affluence. He mentions to Lopakhin that their cherry orchard was once mentioned in the Encyclopaedic Dictionary. The dictionary represents the extinction of aristocracy, who will only be remembered in the pages of history. Varya also dreams of Lopakhin's proposal, but the latter does not feel he deserves Varya. Varya expresses her bitterness to Anya: â€Å"But everybody talks about our marriage, everybody congratulates me, and there's nothing in it at all, it's all like a dream† (Chekhov 1). Indeed, these characters have various dreams that they never act on. Gaev illustrates the futility of dreaming:â€Å"I keep thinking and racking my brains; I have many schemes, a great many, and that really means none.† The play draws the difference between dreaming and realising those dreams. But dreaming is better than having no dreams at all. Chekhov shows that people with no aspirations are more deplorable than those who dream. Yephodov, who earned the nickname of two-and-twenty misfortunes because of his

Roots of conflic, viol and peace Essay Example | Topics and Well Written Essays - 1000 words

Roots of conflic, viol and peace - Essay Example In the effort to bridge this gap, peace paradigms such as power politics and world order were developed. The power politics paradigm, which is dominant in matters of international relations, stipulates that there is an absence of universally acceptable values that would serve all international actors. Power politics in characterized the use of threats by one nation to the other, be it military, political and/or economic (Wight, Bull and Holbraad, 2002). It is as a result of the absence of prevailing international government that renders international politics unpredictable and volatile, with nations perpetually changing alliances. The end result is an exposure to violence, insecurity and power imbalance. According to the power politics peace paradigm, it is imperative for states to engage in the implementation of policies that would effectively serve their national objectives construed as the acquisition of military strength and material power with the aim of deterring and compelling other nations. A nation that is known to possess material and military power is less likely to be expos ed though the acquisition of such rises serious moral and ethical issues. This means that states have no alternative but to attempt to steer away from international humanistic values that are pegged on the trust and good will of nations. The lack of a common and unified moral standard that can be used as the guiding point for international cooperation means that states are left with no alternative but to strive and compete against each other in the quest to attain the perceived security providers (Gandhi Marg Magazine, 2002). The basic idea, therefore behind power politics is that for peace to prevail, people must be prepared for war. The implicit being that the human competitive aspect predisposes the world to violence and it is through the forceful implementation of order, peace is attained. While power politics is not entirely indifferent to issues such as environmental degradation and poverty, it has been criticized for advocating for a moral minimalism approach, meaning that the world has been condemned to a self help attitude, with the stronger nations overpowering less empowered nations (Wight, Bull and Holbraad, 2002). On the hand, the world order paradigm stipulates that peace can be attained through the power of law. It calls for the development of sustainable cooperation among states, inter governmental organization and non governmental organizations. The proponents of world order consider the power politics approach as a recipe of inevitable disorder. They future insist that human have both the potential to be selfish and otherwise and if they so choose, human can cooperate for the sake of the greater good. According to the proponents of the world order, international cooperation is critical in the decentralization state centered international relations models that have completely failed to secure the general interests of human beings. The fact is the world is basically a global village due to immense technological advancements. Issues such as peace, poverty, disease, human rights violations, environmental degradation, disease and weapons of mass destruction, are a major concern to people across the divide. It is for this reason that the world order stresses the on the possibility of humans to choose to cooperate. It also
