This book introduces Tanzanian students to the fascinating world of Mechanics - the science of motion and equilibrium. Concepts of mechanics namely vector and scalar quantities, forces, the laws of motion, work, energy, the conservation laws, gravitation, circular, orbital and oscillatory motions cut across not only most branches of physics such as electromagnetism, atomic, molecular, nuclear, astro and space physics, but are also applied to most branches of engineering and technology. This makes mechanics an important component of physics which students must master well at an early stage before branching to various career options. That is why undergraduate programs in sciences at most universities offer mandatory courses on basic mechanics within the ¿rst year of study. This book meets the needs of students and academics at the entry level courses.This book covers three crucial subareas of mechanics namely Kinematics, Newtonian mechanics and Lagrangian mechanics. Chapter 1 covers introductory aspects. Kinematics is discussed in chapter 2. Newton's laws of motion are introduced in chapter 3. Chapter 4 deals with the conservation of linear momentum. Work, energy and power are covered in chapter 5. Circular motion, Gravitation and planetary motion, and oscillations are covered in chapters 6, 7 and 8 respectively. Chapter 9 presents the aspects of rigid body dynamics, and Lagrangian mechanics is introduced in chapter 10, which lays a foundation for advanced courses in mechanics.The language of physics is universal, and the book is suited to students globally. However, the book recognises and addresses the speci¿c needs of students in African Universities. There is a marked heterogeneity in the background of students ranging from those who are well prepared to those who are not so well prepared. The book meets the needs of all students. It presents detailed explanations of dif¿cult-to-grasp topics with the help of simple but clearly drawn and labeled diagrams. The discussions and conclusions are presented point-wise, and key words, de¿nitions, laws, etc., are highlighted. A unique feature of the book is a number of 'Recipes' which give students tailor made guidance to problems solving. Application of the recipe is illustrated by a solved example, followed by a similar exercise for students to practice. There are a large number of problems and exercises at the end of each chapter to further sharpen their skills.

To be or not to be is an analysis of linguistic, cultural, political, economic and social factors, which explain the intricate root causes of conflicts which have ravished Sudan. It stands in stark contrast to the dominant simplification and distortions which have come to typify presentations of the region. Central to the book is an unapologetic explanation of Arabization; which often is portrayed as individual choices of religious loyalty, but, in fact, masks an intentional power-system which viciously corrupts Afrikan identities. By highlighting the detrimental complexities of manipulation, geopolitics, identity confusion and cultural imperialism, Hashim has not only written an authoritative book about Sudan, but also presented a comprehensive case study that all of Afrika must learn from. Rarely are we presented with such a vigourous inside-view to an area of Afrika which once was held in the highest civilizational esteem, but has been reduced to an ideological field of Arab-led terror, massacres and disintegration.

A Son of Two Countries is a story of struggle for education. Born in 1946 in Rwanda under Belgian colonial rule, the author recounts his early education in Rwanda and later as a refugee in Tanzania. He was naturalized as a Tanzanian citizen in 1980 while doing his undergraduate studies at the University of Dar es Salaam. As he struggled to get education, the author was also grappling with his refugee status, with all the challenges that it entailed.The book gives insights into the contradictions of colonial and post-colonial education, as well as the author's reflections on education in Tanzania, given his long experience in the education sector in that country. Finally, we get some glimpses into the dual identity of the author as a Tanzanian citizen of Rwandan origin and how this shaped his relationship with the two countries he calls home. As he aptly puts it, "Rwanda gave me my heart; Tanzania gave me my brain. I find it difficult to choose between my heart and my brain".

School Development through Teacher Research - Lesson and Learning Studies in Sweden and Tanzania presents the results from a three-year-long joint research project conducted by educational researchers from Tanzania and Sweden. Even though the country contexts differ in social, economic as well as educational conditions, including teacher education and classroom standards, many recurrent education challenges are shared. These include the tendency to make educational reforms with little or no input from professionals. The new educational reforms in both countries put a much higher responsibility on teachers; teachers must be able to organise teaching that enables all students to develop required abilities/competencies. Thus, teachers need tools to develop knowledge that can contribute to their professional knowledge base.With an overall interest in issues of teaching and action research, this joint project aimed to use Lesson and Learning Study as models for developing and improving the quality of teaching and learning in schools. The research project was realised through four case studies in each country with a focus on students' development of specific capabilities and values Science, Vocational Skills/Home and Consumer Studies, English as second language and Mathematics in grades 6-7. Complementing the cases School Development through Teacher Research - Lesson and Learning Studies in Sweden and Tanzania offers an introductory background to Lesson and Learning Studies as models for teacher-driven research and school development. The book is written to support teachers and teacher educators' wishing to reflect about learning and the struggle of learners to discern various concepts, principles and practices. As well as those who genuinely wish to see serious learning take place, rather than simply seeing content 'covered' - including curriculum designers and developers, educational researchers, educational supervisors and leaders and student-teachers as well as students of pedagogy and didactics. We dedicate the book to teacher educators, teachers and school leaders who are seriously striving to enhance students' learning and understanding in different subject areas.

Pastoralism and Climate Change in East Africa provides systematic and robust empirical investigations on the impact of climate change on pastoral production systems, as well as participating in the ongoing debate over the efficacy of traditional pastoralism. This book is an initial product of the Project Building Knowledge to Support Climate Change Adaptation for Pastoralist Communities in East Africa implemented by the Centre for Climate Change Studies of the University of Dar es Salaam with support from the Open Society Initiative for Eastern Africa.Traditional pastoralism has proved to be a resilient and unique system of adaptations in a dynamic process of unpredictable climatic variability and continuous human interactions with the natural environment in dryland ecosystems. Pastoral adaptations and climate-induced innovative coping mechanisms have strategically been embedded in the indigenous social structures and resource management value systems. Pastoral livelihoods have, nevertheless, become increasingly vulnerable to climate change impacts as a result of prolonged marginalization and harmful external interventions. The negative effect of global climate change has been an added dimension to the already prevailing crisis in the pastoral livelihood system, which is substantially driven by non-climatic factors of internal and external pressures of change such as population growth, bad governance and shrinking rangelands lost to competing activities.

Science and Technology are ubiquitous in the modern world as evidenced by digital lifestyles through mobile phones, computers, digital ¿nancial services, digital music, digital television, online newspapers, digital medical equipment and services including e-services (e-commerce, e-learning, e-health, e-government) and the internet. This book, Introduction to Basic concepts for Engineers and Scientists: Electromagnetic, Quantum, Statistical and Relativistic Concepts. is written with the objective of imparting basic concepts for engineering, physics, chemistry students or indeed other sciences, so that such students get an understanding as to what is behind all these modern advances in science and technology.The basic concepts covered in this book include electromagnetic, quantum, statistical and relativistic concepts, and are covered in 20 chapters. The choice of these concepts is not accidental, but deliberate so as to highlight the importance of these basic science concepts in modern engineering and technology. Electromagnetic concepts, are covered in chapters 1 to 6 with chapters 1 (Maxwell's equations), 2 (Electromagnetic waves at boundaries), 3 (Diffraction and Interference), 4 (Optical ¿ber communications), 5 (Satellite communications) and 6 (Mobile cellular communications). Quantum concepts are covered in chapters 7 to 15 with chapters 7 (Wave-particle duality), 8 (The wave function and solutions of the Schrodinger equation in different systems), 9 (Introduction to the structure of the atom), Introduction to materials science I, II, III and IV, in four chapters: 10 (I: Crystal structure), 11 (II: Phonons), 12 (III: Electrons) and 13 (IV: Magnetic materials), 14 (Semiconductor devices), and 15 (Quantum Optics). Statistical concepts are covered in chapters 16 to 19, with chapters 16 (Introduction to statistical mechanics), 17 (Statistical mechanics distribution functions, covering Maxwell-Boltzmann statistics, Fermi-Dirac statistics and Bose-Einstein statistics), 18 (Transport theory) and 19 (Phase transitions). Finally, chapter 20 (Relativity) where Galilean, Special and General Relativity are discussed.

This volume focuses on the cultural memory and mediation of the 1964 Zanzibar revolution, analyzing it's continuing reverberations in everyday life. The revolution constructed new conceptions of community and identity, race and cultural belonging, as well as instituting different ideals of nationhood, citizenship, sovereignty. As the commemoration of the 50th anniversary of the revolution revealed, the official versions of events have shifted significantly over time and the legacy of the uprising is still deeply contested. In these debates, the question of Zanzibari identity remains very much at stake: Who exactly belongs in the islands and what historical processes brought them there? What are the boundaries of the nation, and who can claim to be an essential part of this imagined and embodied community?Political belonging and power are closely intertwined with these issues of identity and history-raising intense debates and divisions over precisely where Zanzibar should be situated within the national order of things in a postcolonial and interconnected world. Attending to narratives that have been overlooked, ignored, or relegated to the margins, the authors of these essays do not seek to simply define the revolution or to establish its ultimate meaning. Instead, they seek to explore the continuing echoes and traces of the revolution fifty years on, reflected in memories, media, and monuments. Inspired by interdisciplinary perspectives from anthropology, history, cultural studies, and geography, these essays foreground critical debates about the revolution, often conducted sotto voce and located well off the official stage-attending to long silenced questions, submerged doubts, rumors and secrets, or things that cannot be said.

Against the background of the carving's beginnings at Konde in Kisarawe District, Tanzania, which attest to the crucial ties between Zaramo social practices and the carved objects that form an integral part of Zaramo life, The Art of the Zaramo presents the transformations, and reinvention of Zaramo wood sculpture in line with forces of modernization and social change. The book confirms that art represents history, culture and society. To find answers to the author's questions and to develop an understanding of how Zaramo figurative sculpture was transformed as it went through modernization, Fadhili Safieli Mshana compelled to consider the impact of the following: Zaramo multiple ethnic heritage, social norms and cultural patterns including Swahili interactions, the strategic proximity of the Zaramo to Dar es Salaam (Tanzania's biggest city and former capital), influences of Islam and Christian missionaries, colonial history, and finally the socio-economic transformation of post-independence Tanzania. These involve examining the ways that art acts as a vehicle for the formation of individual/group identity; how the two entities negotiate each other in the process of social and cultural change. This excellent book then, is about the Zaramo and their figurative wood carving tradition, and it is written as an attempt to not only understand the origins, development, and centrality of this figural carving tradition to the Zaramo, but also, the ways the Zaramo have used select sculptural objects to interpret change and continuity in the midst of modernization and social change.

Elvis Jaramillo is a poor kid from a shantytown; Julián Restrepo is a rich kid taxi driver dreaming of becoming a rock star; Pamela Oswald the NGO worker from London who becomes fatally intertwined in their lives....In an unnamed Latin American country, society eats itself from the inside. Leila Halabi, a 2nd generation Palestinian immigrant, offers to house Pamela Oswald while she works at a rehabilitation centre for poor kids who are self-harming. But when Oswald discovers that Halabi's previous guest disappeared in unexplained circumstances, she becomes uneasy...Julián Restrepo picks Oswald up from the airport when she arrives in the capital city, Santa Fé, and the two become friends. Restrepo introduces her to the other members of his band: Jhonny Cruz the guitarist, Robert Stone, a cynical English journalist, and Raúl Bontera, a Chilean poet who tells Oswald of a new game he discovered in Colombia: Colombian Roulette - like Russian Roulette without the safety of the empty chambers...In a shantytown in distant Guadalajara, Elvis Jaramillo works alongside a mechanic calling himself the Angolan, a testament to his enslaved African ancestors. The Angolan shows Jaramillo how to make a life and survive. But then one of the Angolan's friends makes an offer Jaramillo can't refuse, and he leaves the only world he knows - a world where violence is the best opportunity going, and safety a luxury for those who can forget the past.How to achieve a lasting peace where human weakness and the political order will not allow it? It soon is clear that accepted truths are built on lies, and every alternative offers a route to disappearance. Restrepo and Oswald embark on a dangerous quest for the truth which brings them and Jaramillo together, in a country where the present implodes as the violence of the past is excavated, and the only war that has yet been declared is against itself.
