Development of a potentiometric mefenamate ion sensor for the determination of mefenamic acid in pharmaceuticals and human blood serum

The characteristics, performance, and application of a novel and simple electrode, namely Pt vertical bar Hg vertical bar Hg-2(MF)(2)vertical bar Graphite, where MF stands for mefenamate ion, are described. This electrode responds to MF with sensitivity of (58.9 +/- 0.7) mV decade(-1) over the range 1.0 x 10(-6) to 1.0 x 10(-2) mol L-1 at pH 6.0-9.0 and a detection limit of 6.2 x 10(-7) mol L-1. The electrode is easily constructed at a relatively low cost with fast response time (within 10-25 s) and can be used for a period of 4 months without significant change in its performance characteristics. The proposed sensor displayed good selectivity for mefenamate in the presence of several substances, especially concerning carboxylate and inorganic anions. The potentiometric sensor was successfully applied to the determination of mefenamic acid in pharmaceuticals and human serum samples. (c) 2007 Elsevier B.V. All rights reserved.

Assessing the replacement of lead in solders: effects on resource use and human health

Human health and environmental concerns are not usually considered at the same time. Tin-lead solders are still widely used in several countries, including Brazil, by manufacturers of electronic assemblies. One of the options to reduce or eliminate lead from the manufacturing environment is its replacement with lead-free alloys. This paper applies emergy synthesis and the DALY indicator (Disability Adjusted Life Years) to assess the impact of manufacturing soft solder using tin, lead and other metals on the environment and on human health. The results are presented together with the company's financial results and the results calculated from the Brazilian statistical value of life. The calculation of emergy per unit showed that more resources are used to produce one ton of lead-free solders than to produce one ton of tin-lead solders, with and without the use of consumer waste recovered through a reverse logistics system. The assessment of air emissions during solder production shows that the benefits of the lead-free solution are limited to the stages of manufacturing and assembling. The tin-lead solder appears as the best option in terms of resource use efficiency and with respect to emissions into the atmosphere when the mining stage is included. A discussion on the influence of the system's boundaries on the decision-making process for materials substitution is presented. (C) 2012 Elsevier Ltd. All rights reserved.

Gender equality and human development in Macedonia during transition (1991-2006)

The present thesis treats the issue of gender equality in Macedonia during the period of transition from the socialist system to the one of parliamentary democracy. The main aim is to mainstream the gender perspective in the analysis of the transitional policies through the examination of the basic citizenship rights to which citizens are entitled and by the means of the evaluation of their capabilities to exercise these rights. Gender equality, as one of the main strongholds of the concept of human development is measured through the application of nine gender relevant capabilities in a Case study conducted within selected municipalities in the country. Through the analysis of the Macedonian constitutional and legal framework and the assessment of gender based inequalities, the research questions the need for the enactment of a process of engendering of citizenship, which would integrate gender based differences, contemplate the private sphere of citizens lives and pledge participation in the political life of the country. The thesis, finally, analyses the gender equality strategy of the Macedonian government with the purpose to evaluate whether it is context based, i.e. it tackles the main fields where inequalities emerge and in this context whether it envisages a process of engendering of citizenship.

Concepts for Contemporary Social Work: Globalization, Oppression, Social Exclusion, Human Rights, Etc.

The society wrestles with mass social change congruent with economic globalization and the communications revolution. This change creates new challenges for the social work profession in the areas of social and economic justice. This article analyzes the terminology of the new global era, words that signify a paradigm shift in outlook, most of them a reaction to the new authoritarianism of the age. Globalization, oppression, social exclusion, human rights, harm reduction, and restorative justice are the representative terms chosen.

Shaping EU trade agreements to support human rights

Trade between Europe and developing countries should be shaped such that market shares are just and trade flows foster sustainable development. But this is not always the case. While developing countries have much to gain from trade, they can also suffer serious losses. This is especially apparent with regard to food security, which often depends largely on smallholders and informal markets in poorer countries. This policy brief sketches the link between trade and the right to food, and describes how integration of Human Rights Impact Assessments in EU trade policy can help ensure sustainable trade regimes that do not cause undue harm.

Teachers' Views of Human Rights Education

The Universal Declaration of Human Rights (UDHR) states that education should be "directed to the full development of the human personality and to the strengthening of respect for human rights and fundamental freedoms... promote understanding, tolerance and friendship among all nations, racial or religious groups." This study surveyed 53 teachers on their views of Human Rights Education, including their familiarity with the concept, their self-efficacy with teaching it, and conditions that would increase the likelihood of their teaching it. The study found that, regardless of familiarity with the topic, years of teaching experience, or school location (urban/suburban), most teachers were open to teaching Human Rights Education. They did identify the need for better resources in the form of lesson plans, teaching materials, and professional training. In addition, support from other teachers, administration, and parents was felt to be important in order for them to undertake Human Rights Education. The best strategy to move forward with Human Rights Education would be to provide resources and support for teachers so that we can be living up to the expectations put forth in the UDHR.
