Exploring the potential of using bio briquette ash in building materials
No full textAs the population and urbanization increase, the demand for affordable housing and the environmental
impact of conventional materials have become more pronounced. This study seeks sustainable solutions
through the repurposing of waste products. This study examined the potential application of bio-briquette
ash derived from sanitary sludge in building-material production. Bio-briquette ashes were produced by
incinerating bio-briquette char in an open kitchen at temperatures ranging from 300°C to 450°C.The
chemical composition of bio-briquette ashes produced with different binders (cassava peels, wastepaper,
and no binder) was analyzed using X-ray fluorescence (XRF) and X-ray diffraction (XRD). The results
showed that the ashes contain substantial amounts of oxides, including SiO2, Fe2O3, Al2O3, and CaO,
which are comparable to other supplementary cementitious materials like rice husk ash, sugarcane
bagasse ash, and fly ash. The findings indicate that these bio-briquette ashes have low pozzolanic
properties, however, they have the potential to produce cement-based products after activating their
reactivity either by optimization of burning temperature, mechanical grinding or chemical activation to
improve strength, durability, and workability. Future studies will focus on optimizing the burning
temperature, mechanical grinding, or chemical activation of the bio-briquette ashes to enhance their
reactivity as well as utilizing bio-briquette ash in building materials production and evaluating their
performance in practical applications.The author would like to express gratitude to
the funder of this research project, the Vrilous
Project of Belgium, as well as Ardhi University for
sponsoring this study. Special thanks are
extended to Prof. Elke Knapen from Hasselt
University and Prof. Shadrack M. Sabai from

Title The Impact of Change Management on Organizational Success
Year 2018
Language English
Pages 49+5
Name of Supervisor Peter Smeds
The objective of the thesis was to ascertain the impact of Change Management toward the success of an organization. This literary work considered, the principle for change, how to effectively implement change in an organization, the importance of managing change and the role of management in change.
To add more weight to the study and provide sufficient proof, several models on change management were also utilized in-depth. The thesis focuses on four key models. The four models were used because they have a direct correlation to the objective and, hence, made it much easier to solve the thesis problem. These models include; Lewin’s Change Management Model, McKinsey 7 S Model, Kotter’s Change Management Theory and Kübler-Ross Five-Stage Model.
After a successful study of the topics, it emerged that change requires management and full support of employees. Proper timings should be designed during change implementation. Lastly, a successful change agenda takes into account both internal and external stakeholders, that is, employees, management, and customers
The Journey
No full textThis abstract summarizes a culminating experience project titled The Journey - Global Jazz in Context: Exploring my Journey from Africa (Ghana) to America. The project delves into the author\u27s personal and professional journey from Ghana to the United States, with a focus on their experiences as a musician and the influence of their time at Berklee College of Music. Despite societal limitations and financial constraints in Ghana, the author pursued their passion for music and eventually enrolled in a music program at Berklee. Their goal is to establish an institution that provides music education and resources for young musicians in Africa, addressing the limitations they face. The project incorporates music composition to convey the author\u27s migration story, highlighting the power of diversity and cultural differences. The author\u27s musical compositions reflect their roots and aspirations, incorporating elements from different genres and cultural backgrounds. The project concludes with reflections on the author\u27s growth and the fusion of their education in psychology and music. The Global Jazz Institute at Berklee played a crucial role in inspiring and guiding the author\u27s musical writing, which aligns with their long-term goals. Through this project, the author discovers the potential of global jazz in bridging their African and American identities, contributing to their growth as a versatile musician.https://remix.berklee.edu/graduate-studies-global-jazz/1155/thumbnail.jp

No full textTrends in the Enterprise Resource Planning Market Landscape
No full textThis article provides a brief discussion of ERPs, including how they can be defined, their component parts, and the evolution of technologies since the 1940s. The article then offers a general overview of the current ERP vendor market landscape based on academic journals and industry reports. The article’s methodological approach is a review of both academic literature and industry expert reports, which the author performed to trace trends within the landscape. Results of the analysis demonstrate that the rapidly evolving market landscape dates back at least six decades, and there are many large, longstanding ERP vendors. Yet, opportunities like cloud computing may result in niche products in existing industry players or through start-ups. Nonetheless, technologies such as blockchain are emerging. It remains to be seen how they will impact the ERP market
The Historical Contribution of Black Musicians to Orchestral Classical Music around Johannesburg and the Implications for Cultural Policy
No full textA thesis submitted for the degree of Doctor of Philosophy in Cultural Policy and Management, in the Faculty of Humanities, Wits School of Arts, at the University of the Witwatersrand, Johannesburg, 2023.This study documents the historical contribution of black musicians to classical music in Johannesburg. It places the spotlight on South Africa’s cultural policy (explicitly or implicitly) over the last century and provides ongoing reflections on this period. The thesis analyses the conditions, within and beyond the prevailing policy that enabled black orchestral musicians to practice this art form. By exploring the complex origins of these practices, the study suggests that the dichotomous thinking about culture as either Eurocentric or Afro-centric may be misplaced due to the possibility that Western classical music may have become part of black South African cultural life as a result of having been translated, transferred, hybridised or acculturated. In addition, the study places the government’s arm’s length funding model under scrutiny and finds this approach continues to be applied inconsistently since it was first presented in the White Paper on Arts, Culture and Heritage (1996). As both a classical musician and orchestral administrator, the author has lived part of the history described in the thesis and, through analysis, attempts to establish a dialogue between professional experience and what scholarly reflection can do to that practice. He presents narratives through insider lenses, with carefully selected interviewees, and interrogates situations and sites over a century-long period of the history of black orchestral music practice in South Africa.MM202

Internationalization Process of Two Swedish Firms--The Case of Vaderstad AB and ContextVision AB
No full textBackground: In recent years globalisation has become the recipe for companies to enter foreign market in order to increase sales. Today internationalisation strategy is not limited to large firms as small and medium size firms have taken the challenge to explore international market in order to achieve a sustainable competitive advantage. In this thesis, I and my co-author intend to investigate the internationalisation process of two Swedish firms, Vaderstad AB and ContextVision AB. Purpose: Our aim is to develop a model to provide a solid explanation of today’s Internationalization process. The model will be generated on the basis of studying three models, and the two Swedish firms’ Internationalization process. The model will also be inspired by Luostarinen&Welch (1988 in Kosonen, 1991) dimensions of internationalisation. We aim to suggest this model to firms which intend to begin internationalization process. Result: Two Swedish firms in our thesis conduct different internationalization strategies when they go to international market. Based on the empirical evidence and previous researches it is possible to develop a new model that can provide a holistic view of a firm internationalisation proces
Ultrasound-guided Breast Biopsy in the Resource-limited Setting: An Initial Experience in Rural Uganda
No full textPurpose: To describe the methodology and initial experience behind creation of an ultrasoundguided percutaneous breast core biopsy program in rural Uganda. Methods and Materials: Imaging the World Africa (ITWA) is the registered non-governmental organization division of Imaging the World (ITW), a not-for-profit organization whose primary aim is the integration of affordable high-quality ultrasound into rural health centers. In 2013, ITWA began the pilot phase of an IRB-approved breast care protocol at a rural health center in Uganda. As part of the protocol’s diagnostic arm, an ultrasound-guided percutaneous breast core biopsy training curriculum was implemented in tandem with creation of regionally supplied biopsy kits. Results: A surgeon at a rural regional referral hospital was successfully trained and certified to perform ultrasound-guided percutaneous breast core biopsies. Affordable and safe biopsy kits were created using locally available medical supplies with the cost of each kit totaling $10.62 USD. Conclusion: Successful implementation of an ultrasound-guided percutaneous breast core biopsy program in the resource-limited setting is possible and can be made sustainable through incorporation of local health care personnel and regionally supplied biopsy materials. Our hope is that ITWA’s initial experience in rural Uganda can serve as a model for similar programs in the future
