The specific mechanisms of faecal bacterial removal by constructed wetland (CW) mechanisms are inadequately understood. In several circumstances, CWs have been compared to “black box” systems involving poorly understood waste removal mechanisms despite being an emerging environmentally friendly waste management approach. This has therefore attracted numerous scientific studies to further unlock CWs’ functional mechanisms and to increase its efficiencies. This review paper covers detailed information on the status of detection techniques and removal efficiencies of faecal coliforms, with an emphasis on Escherichia coli. A comprehensive literature search was undertaken that involved a comparative review of various study results and critical analysis of previous scientific and review papers. The ultimate objective is to shed further light on the role of wetlands on wastewater purification for improved aquatic ecosystem health and clean water for humans and other organisms.

Background: Widespread social paradigms on which the status variances are grounded in any society, gender plays pivotal role in manifestation of mental health problems (Rutter, 2007). A hefty volume of research has addressed the issue in adults nonetheless, little is vividly known about the role of gender in adolescent psychopathology. Sample: A sample of 240 adolescents (125 boys, 115 girls) aging 12-18 years was amassed from various secondary schools of Islamabad with the approval of the Federal Directorate of Education (FDE), relevant authorities of the schools and the adolescents themselves. Instruments: Taylor Manifest Anxiety Scale (Taylor & Spence, 1953) and Children’s Negative Cognitive Errors Questionnaire (CNCEQ) by Leitenberg et al., (1986) were applied in present study. Results: Multiple regression analysis revealed that cognitive errors jointly accounted for 78% of variance in predicting anxiety among adolescents. Findings also exhibited that gender significantly moderated the relationship between cognitive errors and adolescent anxiety. Implications of the findings are discoursed for future research and clinical practice.

Introduction. The efficient pharmacotherapy is an important part of palliative and hospice care, and requires a multidisciplinary approach to the patients. The pharmacist, as the member of the multidisciplinary therapeutic team, is responsible for performing pharmaceutical care, which provides safe and efficient treatment. The aim of the research was to conduct a comparative research about the status of palliative and hospice care and role of the pharmacist (clinical pharmacist) in Ukraine and Poland.Material and methods. It was a questionnaire survey conducted in Ukraine, as well as analysis of information sources associated with this subject. The questionnaire was developed on the basis of similar study conducted in Poland. It consisted of 15 multiple-choice questions addressed to head physicians and doctors in Ukraine. The obtained results were compared to the results of the mentioned above Polish study. Results. Eight head physicians and 22 doctors (30 questionnaires) from 13 palliative and hospice care institutions in Ukraine responded to the survey. It has been found that almost half in Ukraine (43%) believed that the pharmacist should be a mandatory member of a multidisciplinary team, because of his/her significant role in drug management in hospice. Conclusion. A multidisciplinary approach to satisfying of patients' needs in palliative and hospice care has a great significance. Results of the study testify to the importance of including the pharmacists into the multidisciplinary team.

Women have many advantages and important roles in the family institution. Nowadays, many women are involved in various professions including entrepreneurship, corporate positions and leadership. Therefore, this article aims to analyse the fundamentals of women’s leadership as the head and manager of the family—roles traditionally reserved for men. This study applies the principles of leadership in the Management Approach on S. Othman Kelantan’s novel, Wajah Seorang Wanita. Library research and qualitative methods were applied in this study. The analysis shows that three out of the four dimensions of leadership principles apply, namely, the administrative, economic and educational dimensions. This is depicted through the novel’s main character, Siti Musalmah, who has to manage and lead her family after the death of her beloved husband. This study also seeks to unveil the role of women and thus elevate the status of women as heads of families despite having to face great challenges as single mothers. As a result, the Management Approach, using principles of leadership, allows a clarification and analysis of the principles of management practiced by women in caring for the well-being of their familis. Wajah Seorang Wanita is a portrayal of the leadership of a woman during the time of the Japanese Occupation.

One measure of the maturity of a device technology is the ease and reliability of applying contact metallurgy. Compared to metal contact of silicon, the status of GaAs metallization is still at its primitive stage. With the advent of GaAs MESFET and integrated circuits, very stringent requirements were placed on their metal contacts. During the past few years, extensive researches have been conducted in the area of Au-Ge-Ni in order to lower contact resistances and improve uniformity. In this paper, we report the results of TEM study of interfacial reactions between Ni and GaAs as part of the attempt to understand the role of nickel in Au-Ge-Ni contact of GaAs.N-type, Si-doped, (001) oriented GaAs wafers, 15 mil in thickness, were grown by gradient-freeze method. Nickel thin films, 300Å in thickness, were e-gun deposited on GaAs wafers. The samples were then annealed in dry N2 in a 3-zone diffusion furnace at temperatures 200°C - 600°C for 5-180 minutes. Thin foils for TEM examinations were prepared by chemical polishing from the GaA.s side. TEM investigations were performed with JE0L- 100B and JE0L-200CX electron microscopes.

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.

The vocative function of an address being the basic one is supplemented and modified by a number of other functions actualized in communication, i.e. the phatic one (establishing and developing the contact with the addressee), the status one (reflecting the status responsibility of the communicants), the emotional and attitudinal one (characterizing the addressee and the attitude of the speaker towards the uttered information). Such modification explains the polyfunctional character of the address in communication. All units of address, just like the components of the addressing functional field, are polysemantic and polysemy comprises every type of an address. According to the communicative tasks the following functions can be stated within the vocative one: nominative (naming the addressee), deixis (identifying the addressee), vocative proper (attracting the addressee’s attention). The field model of addresses’ semantic structures allows to research standard and nonstandard vocatives. The standard addresses form the nucleus of the semantic field under research and characterize stability of their application in one of the above-mentioned functions. Nonstandard vocative lexemes (1 % of the total amount of the experimental material) can play the role of an address under certain circumstances. They form semantically heterogeneous (conditioned by a situation) group, located in the periphery area of the semantic field of addresses. The addresses that include anthroponyms form the most widely used group (64,5 % in Ukrainian and 68,1 % in French), the second place belongs to the addresses with appellatives (34,6 % and 29,9 %, correspondingly). As to the composition of appellatives in the status and role addresses they comprise 36,4 % in Ukrainian and 34,9 % in French. Attitudinal addresses reach 63 % and 65,1 %, correspondingly.

This article explores the role of the African Commission on Human and Peoples’ Rights and the role it plays regarding human rights in individual country situations in Africa. It specifically examines the extent to which it has been able to advance a human rights agenda in countries with long-standing human rights problems. The article uses Swaziland/ eSwatini as a lens to examine the matter, because of the longstanding problems that exist in that country. This is done to indicate how the institution works over time on a country’s human rights problems. The article examines a range of institutional structural matters to establish how these issues affect the role of the Commission in its work. The article examines the way in which the Commission uses its various tools, including its communications, the state reporting processes, fact-finding visits, and resolutions, to determine whether those tools are being used effectively. The article examines how the Commission’s processes issues also affect it work. Issues examined negatively affecting the Commission are examined, including problems with the status of its resolutions and communications, limited compliance with its outcomes, and inadequate state cooperation. Reforms necessary to enhance to role and functions of the Commission are surveyed to determine how the institution could become more effective. The African Union’s (AU|) Kagame Report on AU reform is briefly reviewed to examine the limited view and focus of AU reform processes and why AU reform ought to focus on enhancing human rights compliance. The article makes various suggestions on necessary institutional reforms but also as far as the African Commission’s procedures and methods of work to allow it to have a far more effective role in the promotion and protection of human rights on the continent. It is noted that political will by the AU and African states is the largest obstacle to giving the Commission the necessary independence, support and assistance that it needs to play the role in Africa that it should.
