Enhancing Paracetamol with Silver Metal Ions
Enhancing Paracetamol with Silver Metal Ions 1- Introduction The paracetamol (Fig. 1) is one of the famous analgesic drugs which is commonly named as N-acetyl-4-amino-phenol. Paracetamol has an antipyretic medication with little toxicological side effect [1-7]. The fluorometry [8], luminescence [9], electrochemical [10], nuclear magnetic resonance, mass spectroscopy [11] and liquid chromatography [12] are different analyses techniques used to determination of paracetamol drug in pure and pharmaceutical fashions. Paracetamol has a side effect as hepatotoxic in man and animals if it was taken with over dose [13-17]. Herein in this research paper, we aimed to enhance the efficiency of the drug in the presence of silver metal ions by formation of new complex. This complex was proven using spectroscopic and thermo gravimetric analyses. Fig. 1: Chemical structure paracetamol 2- Experimental 2-1- Materials Reagents (paracetamol and silver(I) nitrate) are in analytical grade and used without further purification. 2-2- Instrumentations The elemental analysis (%carbon, %hydrogen and %nitrogen) results were measured using CHN-2400 Perkin Elmer analyzer instrument. FT-IR spectra were scanned on Bruker FT-IR spectrophotometer within 4000-400 cm-1 region. The UV-vis. spectra of reactants and silver(I) complex were scanned using Perkin-Elmer Lambda 4B spectrophotometer in dimethyl sulphoxide solvent. The thermo gravimetric analyses TG/DTG were carried out in nitrogen atmosphere using Schimadzu TGA-50H thermal analyzer. 2-3- Synthesis The 1 mmol of AgNO3 was dissolved in 20 mL distilled water and then mixed to 20 mL of methanolic solution of paracetamol with 1 mmol ratio under magnetic stirring. The pH of mixture was neutralized at 7-8 using diluted ammonium hydroxide solution. The mixture was refluxed at 60 à ¯Ã¢â¬Å¡Ã °C and left to evaporate slowly at room temperature. The precipitate was filtered off, washy with hot methanol and dried at 60 à ¯Ã¢â¬Å¡Ã °C. 2-3- Microbiological investigation The biological activity of silver(I) complex was tested against bacteria and fungi with more than one test organism. The organisms used in the present investigation including two bacteria (B.subtilis Gram +ve), (E. coli Gram ââ¬âve) and two fungi (Aspergillus niger and Aspergillus flarus). The results of microbiological investigations of bacterial and fungi against synthesized silver(I) complex were assessments. 3- Results and Discussion 3-1-Elementl analyses The experimental data of %carbon, %hydrogen and %nitrogen are matched with the calculated values (Table 1). The elemental analyses results are support that NO3à ¯Ã¢â ¬Ã ions not detected. The silver(I) complex is air stable with highly melting point > 300 oC.

â (à ¯Ã 1. cm2.mol-1) at 25 à ¯Ã¢â¬Å¡Ã °C. This data suggested that silver(I) complex is non-electrolytes. 3-3- Infrared spectra The infrared assignments data of paracetamol free drug and its silver(I) complex are tabulated in Table 2 and silver(I) complex is shown in Fig. 2. Based on the comparison between the infrared spectra of free paracetamol drug ligand and its silver(I) complex, it has been discussed that, the absorption band at 3300 cm-1 and 3200 cm-1 of free paracetamol have been assigned to ââ¬âOH and ââ¬âNH stretching vibration motions. These bands have been absence in the spectra of the silver(I) complex due to the involvement in complexation. The strong-to-medium absorption bands at 1650 and 1260 cm-1 in the spectrum of para drug are assigned to the stretching vibration bands of à ¯Ã à ®(C=O) and à ¯Ã à ®(C-O), respectively. These bands are shifted to lower wavenumbers at 1627 and 1100 cm-1 due to sharing in coordination mode. The presence of new absorption band at 510 cm-1 in silver(I) complex is assigned to à ¯Ã à ®(Ag -O) stretching vibration. Upon the infrared spectral assi gnments, the silver(I) ions coordinated to para drug through two place of coordination (deprotonated of ââ¬âOH) and (deprotonated of ââ¬âNH and oxygen of carbonyl group) as shown in Fig. 3.

It can see that free para has two absorption bands at 300 and 390 nm due to à ¯Ã à °-à ¯Ã à °* intra-ligand transition of the aromatic ring and n-à ¯Ã à °* electronic transition, respectively. 3-5- Thermo gravimetric analyses The heating rate was controlled at 10à ¯Ã¢â¬Å¡Ã °C/min under nitrogen environment. The weight loss was scanned from room temperature till 1000 à ¯Ã¢â¬Å¡Ã °C. The thermo gravimetric curve of silver(I) complex is shown in Fig. 4. The thermal decomposition of [Ag2(para)] complex exhibit at two step. These steps are occurring at 200-1000 à ¯Ã¢â¬Å¡Ã °C and corresponding to the decomposition of para molecule with a weight loss of 11.4%. The final residual product is silver metal contaminated with few carbon atoms.

Employment and Trade Unions Essay
Throughout the study I have tried with the best of my capacity to accommodate as much information and relevant issues as possible and tried to follow the instructions as you have suggested. I tried my best to make this report as much informative as possible. I sincerely believe that it will satisfy your requirements. I however sincerely believe that this report will serve the purpose of my course (Industrial Relation). I am grateful to you for your guidance and kind co-operation at every step of my endeavor on this report. My effort will be reworded only if it adds value to the research literature. Introduction One of the major functions of human resource management is to maintain smooth industrial relations (IR). It is also treated as one of the oldest functions of HRM. It is basically allied with the relations between the employer and the workers in the industry (Singh & Kumar, 2011: 3). According to Weeratunga (2003:5) ââ¬Å"Industrial Relations or Labor Relations, the terms used interchangeably, can be viewed as the interaction between the various interested parties involved in employment. The employer and the employee are obvious parties. The state, in ensuring a level playing field for both sides, provides the legal framework within which such relations may take placeâ⬠. In industrial relations, workers are generally represented by their trade unions formed under chapter 13 of Bangladesh Labor Actââ¬â2006 whereas employers are represented by their associations such as Bangladesh Employers Federation. HR managers mediate the relationships between workers and employers though they are appointed by the representatives of employers. Another related term is ââ¬ËEmployee Relationsââ¬â¢. Though both the terms industrial relations and employee relations are structurally similar (Decenzo& Robbins, 1999: 18), employee relations includes, in addition to industrial relations, such aspects as participative management, employee wellbeing, employee development, employee compensation, employee protection and health, and the like (Aswathappa, 2008:534). Generally industrial relations cover the areas such as trade unions, collective bargaining, settlement of industrial disputes, grievance handling procedure, role of government, labor laws, courts and tribunals and role of employers. In the context of developing countries, industrial relations has been influenced by features such as high exploitation of workers, low level of worker participation in decision making, government and political interferences, high rate of illiteracy of workers, low level of employment, low level of awareness among the laborers regarding rights, laws, and trade unionism, and low labor productivity (Khan &Taher, 2008: 222-23). Industrial relations plays an important role in establishing and maintaining industrial democracy (Monappa, 2004: 9) and it is the key to improve productivity in industrial enterprises (Aswathappa, 2004: 534). Human resource management can play vital roles in enhancing cooperative and friendly industrial relations. In Bangladesh, collective bargaining on pay between employer and workmen is prohibited in the public sector enterprises as the government designs uniform pay and benefits for the employees of all public sector enterprises (Mahmood, 2008). The limited scope of collective bargaining in the public sector of Bangladesh influences the trade unions to develop network with government, political parties and other powerful bodies in organizing their activities. It hinders effective interactions between the representatives of employers and workers at enterprise level. Though performance based pay is considered to have significant impact on employee performance (Dessler&Varkkey, 2010: 15), it is not at all practiced by the public sector enterprises in Bangladesh. As a result, public sector enterprises in Bangladesh have been incurring huge losses. On the other hand, all types of collective bargaining takes place at enterprise level in case of private sector enterprises (Khan, 1996). Mahmood (2008) mentioned that the industrial relations process in the private sector was often disturbed by links between private and public sector unions. Objectives: a) To explore the differences between public and private sector industrial enterprises of Bangladesh with respect to overall status of IR. b) To put forward policy implications of overall improvement in IR of Bangladesh. Industrial Relations Studies in Bangladesh Khan (1986) studied industrial relations in Bangladesh with special emphasis on trade unionism. â⬠¦ Trade Unions Trade Union is an organization of workers who have banded together to achieve common goals such as protecting the integrity of its trade, achieving higher pay, increasing the number of employees an employer hires, and better working conditions. An organized association of workers in a trade, group of trades, or profession, formed to protect and further their rights and interests. ââ¬â A group of employees in a particular sector, whose aim is to negotiate with employees over pay, job security, working hours, etc. using the collective power of the members. The most common purpose of these associations or unions is ââ¬Å"maintaining or improving the conditions of their employmentâ⬠. Causes of organizing trade unions Provision of benefits to members: professional training, legal advice and representation for members is still an important benefit of trade union membership. Industrial action: Trade unions may enforce strikes or resistance to lockouts in furtherance of particular goals. Political activity: Trade unions may promote legislation favourable to the interests of their members or workers as a whole. To this end they may pursue campaigns, undertake lobbying, or financially support individual candidates or parties. Conditions of employment and any grievances ââ¬â are settled through trade unions. Bargaining rights: Trade unions bargain and ensure the status, rights, wages and demands of workers of the modern world of industry. Contribution in economical growth: Trade unions are growing rapidly in an economy because of the expansion of business and economical growth. Objectives Trade unions are the only way to manage, compliant, and control the labour force. Lots of objectives are there to organize trade unions. . To defend or improve the wages and working conditions of workers and to bring about a change in the economic order. 2. To strengthen their (labour) bargaining power collectively to establish and achieve all their rights. 3. To dully protect all other interest of the workers . And from the managementââ¬â¢s point of view the objectives as written: a) To reduce the number of negotiation. b) To specify work rules, disagreements and grievances to give the better solution to workers claim. c) To establish the efficient communication between the employers and management to enforce the predictable standards. ) To enhance the overall organizational effectiveness workers can also be sometimes inspired to form and organize trade union. In fact, objectives of a trade union are not defined; rather these are changing according to the need of the economy and overall industry. When these objectives are not settled then the rivals are started History of Trade Unions The Pakistan Period (1947-71) -The East Pakistan Trade Unions Act, 1965 was enacted repealing the Trade Unions Act, 1926. -The Labor Disputes Act, 1965 was enacted. -Industrial Relations Ordinance, 1969 was enacted integrating the above two Acts. Bangladesh Period (1971-onwards) -Government of Bangladesh declared a labor policy in 1972. The right to strike and collective bargaining in the nationalized industries was prohibited for six months by Presidential order no. 55 in May 1972. -In 1973, the right to strike and lockout, as granted by IRO, 1969 was withdrawn. -In 1974 Act completely suspended the democratic rights of workers by prohibiting trade union activities such as strikes, lock-outs, collective bargaining. -The military regime of 1975 imposed restrictions on the rights of collective bargaining. The Industrial Relations (Amendment) Ordinance, 1977 liberalized the Rights of Freedom of Association -The Labor Policy of 1980 restored the right to freedom of association to a considerable extent -In 1982 the military regime banned trade union activities, strikes, and right of freedom of association. Limitations In Bangladesh Trade Unions have a lot of unavoidable problems: 1. Lack of consciousness: Trade union are not actu ally completely aware about employees legal rights and duties. 2. Lack of Unity: In Bangladesh trade unions are separated for political influence. 3. Lack of knowledge: The workers of Bangladesh donââ¬â¢t have enough knowledge about their rights and duties. 4. Political influence: In Bangladesh, trade unions work a part of political parties not as a free right saving association. 5. Division of trade union: Bangladesh is a country where every organization has more trade unions in name only. The overall productivity got down. Suggestions Strengthening bilateral collective bargaining for solving problems quickly and effectively. Multiplicity of trade union creates the rivals in a union. So it must be reduced. Political involvement must be reduced. Organization must support financially as trade unions support the worker. Training programs under trade union should be helpful to develop the skills of the workers. Trade unionââ¬â¢s function should be increased and widened throughout the organization. Union leader must be given importance and encourage the members. If trust between workers and management increases, productivity increases. Management must help and guide trade unions to settle industrial clashes and crisis. Trade unions always should demand reasonable thing to the management. . What is a dispute? Academically speaking, industrial dispute refers to any conflict between employees and employers, between employers and employers and between employers and employees. â⬠¢ But in reality, dispute is understood as the conflict between employees and employers. There are three types of Disputes : â⬠¢ Disciplinary disputes â⬠¢ Grievance disputes â⬠¢ Industrial disputes â⬠¢ According to Industrial Dispute Act, 1947, Industrial dispute means any dispute or difference between employers and employers, or between employers and workmen, or between workmen and workmen, which is connected with the mployment or non-employment or terms of employment or with the conditions of labour of any person. Causes of Industrial Disputes: Some of the prominent causes of industrial disputes may be listed thus: Employment: The list here includes disputes over wages, allowances, bonus, benefits, working, condition, unjust dismissals, retrenchment of workers, methods of job evaluation, changes in methods of production, non-implement of awards of tribunals, etc. The National Commission on Labor remarked ââ¬Å"though on majority of occasions industrial disputes were based on claims pertaining to the terms and condition of employment, sometimes economic issues of a general character dominated and, on occasion, purely motivesâ⬠. The causes of industrial disputes can be broadly classified into two categories: economic and non-economic causes. The economic causes will include issues relating to compensation like wages, bonus, allowances, and conditions for work, working hours, leave and holidays without pay, unjust layoffs and retrenchments. The non economic factors will include victimization of workers, ill treatment by staff members, sympathetic strikes, political factors, indiscipline etc. Wages and allowances:à Since the cost of living index is increasing, workers generally bargain for higher wages to meet the rising cost of living index and to increase their standards of living. In 2002, 21. 4% of disputes were caused by demand of higher wages and allowances. This percentage was 20. 4% during 2003 and during 2004 increased up to 26. 2%. In 2005, wages and allowances accounted for 21. % of disputes. Personnel and retrenchment:à The personnel and retrenchment have also been an important factor which accounted for disputes. During the year 2002, disputes caused by personnel were 14. 1% while those caused by retrenchment and layoffs were 2. 2% and 0. 4% respectively. In 2003, a similar trend could be seen, wherein 11. 2% of the disputes were caused by personnel, while 2. 4% and 0. 6% of disputes were caused by retrenchment and layoffs. In year 2005, only 9. 6% of the disputes were caused by personnel, and only 0. 4% were caused by retrenchment. Indiscipline and violence:à From the given table, it is evident that the number of disputes caused by indiscipline has shown an increasing trend. In 2002, 29. 9% of disputes were caused because of indiscipline, which rose up to 36. 9% in 2003. Similarly in 2004 and 2005, 40. 4% and 41. 6% of disputes were caused due to indiscipline respectively. During the year 2003, indiscipline accounted for the highest percentage (36. 9%) of the total time-loss of all disputes, followed by cause-groups wage and allowance and personnel with 20. 4% and11. % respectively. A similar trend was observed in 2004 where indiscipline accounted for 40. 4% of disputes. Bonus:à Bonus has always been an important factor in industrial disputes. 6. 7% of the disputes were because of bonus in 2002 and 2003 as compared to 3. 5% and 3. 6% in 2004 and 2005 respectively. Leave and working hours: Leaves and working hours have not been so important causes of industrial disputes. During 2002, 0. 5% of the disputes were because of leave and hours of work while this percentage increased to 1% in 2003. During 2004, only 0. % of the disputes were because of leaves and working hours. ? Miscellaneous:à The miscellaneous factors include ââ¬âà à Inter/Intra Union Rivalry ââ¬âà à Charter of Demands ââ¬âà à Work Load ââ¬âà à Standing orders/rules/service conditions/safety measures à à ââ¬âà à Non-implementation of agreements and awards etc. Collective Bargaining Collective bargaining includes not only negotiations between the emp loyers and unions but also includes the process of resolving labor-management conflicts. Thus, collective bargaining is, essentially, a recognized way of creating a system of industrial jurisprudence. It acts as a method of introducing civil rights in the industry, that is, the management should be conducted by rules rather than arbitrary decision making. It establishes rules which define and restrict the traditional authority exercised by the management. Importance to employees ? Collective bar aining develops a sense of self respect and responsibility among the employees. It increases the strength of the workforce, thereby, increasing their bargaining capacity as a group. Collective bargaining increases the morale and productivity of employees. It restricts managementââ¬â¢s freedom for arbitrary action against the employees. Moreover, unilateral actions by the employer are also discouraged. Effective collective bargaining machinery strengthens the trade unions movement. The workers feel motivated as they can approach the management on various matters and bargain for higher benefits. It helps in securing a prompt and fair settlement of grievances. It provides a flexible means for the adjustment of wages and employment conditions to economic and technological changes in the industry, as a result of which the chances for conflicts are reduced. Importance to employers 1. It becomes easier for the management to resolve issues at the bargaining level rather than taking up complaints of individual workers. 2. Collective bargaining tends to promote a sense of job security among employees and thereby tends to reduce the cost of labor turnover to management. 3. Collective bargaining opens up the channel of communication between the workers and the management and increases worker participation in decision making. 4. Collective bargaining plays a vital role in settling and preventing industrial disputes. Importance to society: 1. Collective bargaining leads to industrial peace in the country 2. It results in establishment of a harmonious industrial climate which supports which helps the pace of a nationââ¬â¢s efforts towards economic and social development since the obstacles to such a development can be reduced considerably. 3. The discrimination and exploitation of workers is constantly being checked. 4. It provides a method or the regulation of the conditions of employment of those who are directly concerned about them.

Manifest Destiny Essay - 788 Words
Manifest Destiny can be described as a belief, in the 19th century, that North-America was destined to stretch from coast to coast and that the expansion of the U.S. throughout the American continents was both justified and inevitable. It is responsible for changing the face of America and creating a new nation (Lubragge, 1809-1900). North-Americaââ¬â¢s westward expansion was due the American belief ââ¬Å"that the strength of American values and institutions justified moral claimsâ⬠¦Ã¢â¬ , land west of the Mississippi River ââ¬Å"were destined for American-led political and agricultural improvement.â⬠, and that ââ¬Å"God and the Constitution ordained an irrepressible destiny to accomplish redemption and democratization throughout the world.â⬠(Beatty et al.,â⬠¦show more contentâ⬠¦Jackson ââ¬Å"led military forces into the Floridaââ¬â¢s during the Florida crisis.

Since American Indians controlled almost all the land in the west and much of the land east of Mississippi River, expansion of the U.S. hinged on the federal policy of Indian removal (Beatty et al., 2017). The Indian Removal Act of 1830 gave president Jackson authority to begin a treaty where American Indians would receive land in the West in exchange for their land east of the Mississippi River (Beatty et al., 2017). That was the start of the North-American expansion. In 1845 North-America started moving west, it appropriated Texas, New Mexico, California, Oregon, and Arizona Between 1845 and 1848, and Alaska in 1867 (Burnsted, 193-95). Americans had a dream of creating a democratic utopia in the west and thanks to technology that improved travel conditions such as roads, railroads, and steamboats the expansion to the west was possible.

Air Pollution Is Something That Every Country Suffer From.
Air pollution is something that every country suffer from. The United States of America is one of those countries. According to Environmental Protection Agency (EPA), pollution levels in many areas of the United States exceed national air quality standards. With air pollution exceeding air quality, some political parties are willing to take action, while others are not. Understanding the most current presidential candidatesââ¬â¢ views on air pollution is vital to ensure who will protect the children, the people of the future.
