    Distributed generations (DG) are being installed at increasing rates, both in developed and developing countries. The increasing number of DG connected to the distribution system could have a significant impact on the power system operation. This paper presents a case study investigating the impact of grid-connected DG on the Nigerian power network in terms of bus voltages and network losses. The results showed that without DG, some of the bus voltage magnitudes of the test system were outside the permissible voltage limit of 0.95pu≤Vi≤1.05p.u. However, with DG connected, the voltage magnitudes were improved to allowable values. The network active power loss was reduced by 12.03% from 85.60MW to 75.30MW. In this way, the power system becomes more efficient and secured

    No full text
    PublishedThis book presents a nuanced and comprehensive examination of the Developing-8 Organization for Economic Cooperation, encapsulating its historical evolution, sectoral initiatives, challenges, and future prospects. Beginning with an insightful account from the Istanbul Seminar to the Istanbul Declaration, the book contextualizes the formation, objectives, and structural dynamics of the D-8, setting a solid foundation for understanding its role in fostering South-South cooperation. The book methodically explores the D-8′s multisectoral initiatives across agriculture, trade, industry, energy, and tourism, highlighting key achievements such as the Dispute Settlement Mechanism, the Preferential Trade Agreement, and the establishment of specialized research centers. Sector-specific analyses provide a critical lens on the D-8′s potential in high-technology production, sustainable energy, and regional integration, with a focused case study on Nigeria’s energy sector. Furthermore, the book offers an indepth look at the economic profiles and sectoral opportunities of member states, emphasizing the significance of intra-trade relations in driving economic development. The role of education systems in transitioning D-8 countries towards knowledge-based economies is meticulously examined, alongside Malaysia’s strategic economic cooperation under the MADANI government’s vision. A critical analysis of the D-8′s legal and policy frameworks underscores their role in shaping economic cooperation, while discussions on climate-smart agriculture and sustainable energy highlight future pathways for ensuring food security and economic resilience. Concluding with an evaluative discourse on the D-8′s challenges and opportunities within the global economic landscape, this book serves as an essential academic resource, offering scholars, policymakers, and stakeholders a well-rounded understanding of the D-8′s trajectory and its potential for fostering sustainable economic development in the Global South. The book will appeal to students, scholars, researchers of economic, international relations, history and management in general. It will also be helpful for public policymakers in the D-8 and outside the member states that are interested in understanding the dynamics, progress, cooperation and challenges of the D-8

    Humanitarian intervention and the protection of civilian populations

    No full text
    The author interrogates the critical question of whether forcible humanitarian intervention be legitimised in spite of clear contradiction to the classical norms of inter-state relations. Classical approach puts emphasize on the principle of sovereignty when governments become the perpetrators of human rights abuses of their citizens, or if states have collapsed into civil war, chaos, and disorder. The author examines this security debate by juxtaposing the age-old doctrine of humanitarian intervention vis-à-vis the imperatives of the concept of ' Responsibility to Protect'. The author argues that humanitarian intervention, due to the ambiguities and controversies surrounding its application, has become an anachronism, which ultimately led to the conceptualisation of Responsibility to Protect vulnerable populations. This approach is based on its concerns with human security as against that of the state and its relevance as arbiter to the longstanding discord between sovereignty and intervention

    AUSTRALIA, NEW ZEALAND AND REGIONAL SECURITY IN THE PACIFIC: REFLECTIONS ON PEACEKEEPING IN THE SOLOMON ISLANDS AND PAPUA NEW GUINEA (BOUGAINVILLE)

    No full text
    This paper examined conflicts and regional security in the Pacific. The paper has as its focus the roles of Australia and New Zealand (and the Pacific Islands Forum) in managing security in the Pacific using Papua New Guinea (Bougainville) and the Solomon Islands as case studies. It documented their peacekeeping experiences, and interrogated whether these operations were successes or not and why. Furthermore, the author explored whether the peacekeeping experiences in the Pacific and lessons learnt from these operations might be applicable to, and/or be helpful in developing a useful peacekeeping model for other regions. The argument of this paper is that, although Australia and New Zealand regional security management role is based on security concerns of the region but the national interests of these dominant states are also at play and a key factor that shape the nature and direction of interventions. As well, the dynamics of these operations have revolved around interaction between and among local, regional and global political factors. The author argued that peacekeeping in the Pacific (especially in Bougainville and the Solomon Islands) may not offer an appropriate peacekeeping model in such-conflict ridden settings as Africa where armed violence are more complex, protracted and involve full-scale military actions as opposed to low-intensity and localised conflicts in the Pacific, but some of the peacekeeping lessons from the region may be helpful to other peace operations, especially Peacekeeping the 'Pacific Way'.     </jats:p

    The African Mission in Burundi (AMIB): A Study of the African Union’s Peacekeeping Success and ‘Triangular Area of Tension in African Peacekeeping’

    No full text
    This article examined the African Mission in Burundi (AMIB), assessed its success and drew lessons learned from the experience. The author argued that the mission was successful in restoring peace and stability in Burundi, although the disarmament, demobilisation and reintegration (DDR) component of its mission was not achieved. The willingness of the African Union (AU) to send a peacekeeping mission as a stabilizing force within an ongoing conflict shows that the organization is serious about tackling security issues on the continent. In spite of AU’s endeavours, the article establishes that the AU is being challenged by what is called the ‘triangular area of tension in African peacekeeping (AU’s ambitions versus AU’s peacekeeping capacities versus member states’ political will and agendas). The article concludes with a reflection on lessons learnt from AMIB as a prelude to addressing this area of tension for better future peacekeeping performances in Africa.</jats:p

O trabalho tem como foco os papéis da Austrália e da Nova Zelândia (e do Fórum das Ilhas do Pacífico) na gestão da segurança no Pacífico usando a Papua Nova Guiné (Bougainville) e as Ilhas Salomão como estudos de caso. Documentou suas experiências de manutenção da paz e interrogou se essas operações eram sucessivas ou não e por quê. Além disso, o autor explorou se as experiências de manutenção da paz no Pacífico e as lições aprendidas com essas operações podem ser aplicáveis e / ou ser úteis no desenvolvimento de um modelo útil de manutenção da paz para outras regiões. O argumento deste artigo é que, embora o papel de gerenciamento de segurança regional da Austrália e da Nova Zelândia seja baseado em preocupações de segurança da região, os interesses nacionais desses estados dominantes também estão em jogo e é um fator chave que molda a natureza e a direção das intervenções. Além disso, a dinâmica dessas operações giram em torno da interação entre os fatores políticos locais, regionais e globais. O autor argumentou que a manutenção da paz no Pacífico (especialmente em Bougainville e nas Ilhas Salomão) pode não oferecer um modelo apropriado de manutenção da paz em ambientes tão conflitantes como África, onde a violência armada é mais complexa, prolongada e envolve ações militares em grande escala em oposição a conflitos de baixa intensidade localizados no Pacífico, mas algumas das lições de manutenção da paz da região podem ser úteis para outras operações de paz, especialmente a Manutenção da paz do "Caminho do Pacífico"

    室蘭工業大学Muroran Institute of Technology博士(工学)application/pdfMany biologically active compounds, including pharmaceuticals, are optically active and often only one of the enantiomer shows a high biologically activity. Therefore, it is important to develop the synthetic methodology for providing only necessary enantiomer. As the methodology, catalytic asymmetric synthesis, in which the use of a low amount of a chiral catalyst theoretically enables infinite production of optically active compounds, is the most efficient in the synthetic organic chemistry field. Moreover, this methodology is also important in terms of energy saving and environmental friendliness. The chiral catalysts used in catalytic asymmetric syntheses can be divided into two categories of organometallic catalyst and metal-free organocatalyst. Particularly, organocatalyst is stable in air, easy to handle, and inexpensive, so they are being focused on as next-generation, environmentally friendly catalysts. Author developed the new type amino amide organocatalyst. This catalyst is expected to work as multipoint recognition catalyst having both covalent and non-covalent hydrogen bonding sites in the single molecule. This catalyst was successfully derived from commercially available amino acids, and the excellent catalytic activities were demonstrated in both (1) the aldol reaction and (2) the Michael addition. (1)The enantioselective asymmetric aldol reaction of ketones with aldehydes using amino amide organocatalysts was carried out to provide chiral aldol products in excellent chemical yields, diastereoselectivities and enantioselectivities. The obtained aldol products are important synthetic precursors of the synthesis of many biologically active compounds including pharmaceuticals. (2)The enantioselective asymmetric Michael reaction of ?-keto esters with nitro olefins using amino amide organocatalysts was carried out to provide chiral Michael adducts in excellent chemical yields, diastereoselectivities and enantioselectivities. The obtained Michael adducts with chiral quaternary carbon center are important synthetic precursors of the synthesis of many biologically active compounds including pharmaceuticals such as platencin (antibiotic). In this study, author revealed that the new explored amino amide organocatalyst showed satisfactory catalytic activities in both (1) the aldol reaction and (2) the Michael addition. It is expected that this results should be able to greatly contribute the development of new drug and its related compounds.薬品を含む多くの生物活性化合物は光学活性物質であり, その鏡像異性体は異なる生体内活性を示すことが多いため, 有効な一方の鏡像異性体を高選択的に合成するための不斉合成反応,特に不斉触媒を用いる触媒的不斉合成反応の開発が重要である.その不斉触媒の中で,金属を含有しない有機分子触媒は空気中で安定であり取り扱いやすく安価であるという利点などを有するため, 次世代の環境調和型触媒として現在活発に研究開発が行なわれている.著者は, 新規多点認識型有機分子触媒としてアミノアミド型触媒を設計し, それを, エナンチオ選択的 (1) ケトン類とアルデヒド類との不斉アルドール反応,(2) s-ケトエステル類とニトロスチレン類 との不斉マイケル付加反応にそれぞれ適用し,その有機分子触媒としての機能性を明らかにした.(1) 新規有機分子触媒としてアミノアミド有機分子触媒Aを合成し, 触媒Aを用いるケトン類とアルデヒド類との不斉アルドール反応を検討した.その結果, 触媒Aが本反応において不斉触媒活性を示し,優れた化学収率と良好な光学収率で光学活性アルドール生成物を与えることを見出した. 得られた反応生成物は,創薬のための様々な生物活性化合物の合成中間体として有用であり,この合成中間体から新薬候補化合物を創製できることが期待される.(2) アミノアミド有機分子触媒Aを用いるs-ケトエステル類 とニトロスチレン類との不斉マイケル反応を検討した.その結果,触媒Aが不斉触媒活性を示し, 本反応によってほぼ完全な化学収率と優れた光学収率で光学活性マイケル付加体が得られることを見出した.得られたマイケル付加体は,創薬のための様々な生物活性化合物の合成中間体として有用であり,この合成中間体から新薬候補化合物を創製できることが期待される.本研究において著者は,「基質との共有結合部位と水素結合部位,さらには反応のエナンチオ選択性の制御に有効な多環式芳香族環部位を併せ持つ多点認識型アミノアミドハイブリッド型触媒」を開発することに成功し, それらが創薬に有効な不斉アルドール反応および不斉マイケル付加反応においてそれぞれ良好な不斉触媒活性を示すことを明らかにした. また,本反応によって得られる化合物は様々な医薬品をはじめとする生物活性化合物の合成中間体として有用であることから,本研究の成果は, 新薬創製の合成開発研究に大きく貢献できると期待される.doctoral thesi
