    This dissertation focuses on an in-depth review of literature on concrete crack repairs. Deterioration of concrete affects both the aesthetics and the integrity of structures. As a result, there is need to repair such defects in order to restore the aesthetics and the integrity of concrete structures. This research discusses concrete crack repairs taking into consideration the mechanisms resulting in concrete cracking, techniques to determine concrete cracking, practices for prevention of concrete cracking and concrete crack repair techniques. Causes of cracking include alkali silica reactions (ASR), steel reinforcement corrosion, shrinkage, thermal variations, foundation movements, soil settlement, vegetation effects and cracking related to earthquale effects. Non-destructive and destructive techniques to determine conrete cracking shall be discussed. Destructive techniques usually involve core drilling of samples whilst non-destructive techniques include visual inspections, ultrasonic pulse velocity test, acoustic emission, spectral analysis of surface waves, modal analysis, petrographic analysis and infrared thermography. Several concrete crack repair techniques are to be discussed such as epoxy injection, routing and sealing, near surface reinforcement, additional reinforcement, gravity filling, grouting, dry packing, crack arrest, polymer impregnation, overlay and surface treatments, crack filling, crack sealing, blanketing, stitching and external stressing. These techniques are applied differently depending on the nature and cause of the concrete cracks. Further discussions will be on various case studies around the world on concrete crack repair which demonstrate the application of various concrete crack repair techniques to different types of concrete cracking scenarios. The case studies also highlight recent developments in technology, repair materials, application fields for various techniques and limitations to concrete crack repair. Some of the case studies discussed include concrete crack repair due to ASR damage on transport infrastructure in USA, ASR effects and crack repairs on a two storey building in California (USA), ASR effects and crack repairs to concrete structures in Hokuriku District in Japan, ASR effects and crack repairs to a gravity dam in India, crack repairs at Buttermarket Shopping Center due to shrinkage cracking and concrete crack repairs in Cheshire due to thermal effects

    A Framework for the Selection of an Entry Mode into International Markets for Practical Green Energy Limited

    Given the global reality of businesses this day, the world even though it may seem a small place still necessitate the requirement of a strategic plan, and to evaluate and implement an entry into a foreign market where that market is not indigenous to the parent company because of the inherent political risk, financial risk, and foreign exchange risk of repatriation of funds. Should this evaluation not be carried out, which will form the basis of the strategic decision making with regard to a foreign investment, then the company’s whole investment plan could be at stake. Planning for international market entry is a continuing open-ended process. There are a number of important factors that relate to how investors can operate in a foreign country; such factors include the rules and regulations pertaining to the entry and operations of foreign investors, standards of treatment of foreign affiliate, the functioning and efficiency of local markets, trade policy and privatization policy, business facilitation measures and incentives, and restrictions. This study is motivated by the need to understand and evaluate the different entry modes available to PGEn, a UK-based R&D company in a bid to helping it decide on the best entry mode for achieving its international expansion objective. The study looked to evaluate the overall risks by analysing relevant qualitative aspects of foreign investment entry; however the eventual decision with regard to a yes or a no rests with the Directors of PGEn. The main aim of this project is to build a model which highlights the important considerations for the selection of an entry mode. The considerations include external (country-specific and industry-specific) factors and internal (firm-specific) factors that influence entry mode decision. The model is to be used as a guide for the company’s entry mode selection decision into different countries. This project then details recommendations to PGEn as to the choice of its entry mode into its first target country, India. Primary data from interviews with the key decision maker of the company, and theoretical findings from secondary sources of data such as journals, websites, text book and other publications were analysed to obtain in-depth understanding of the company, the market and existing policies for use in the construction of the model

    Rethinking conversion : beyond the religious and the secular

    Get PDF
    This article seeks to pinpoint some of the consequences of the secularization process – conceived as the dissociation of religion from both state politics and culture – with the aim of broadening the conceptualization of conversion. Conversion is therefore considered to be a social fact beyond the religious and the secular, for which the concept of 'trans-formation' is employed in order to grasp this phenomenon. The concept of trans-formation posits processes of conversion as shifts from intimate convictions to public values. From this perspective, based on a pragmatic sociology of values, religious conversions are put forth as one possible way to qualify trajectories that the concept of trans-formation aims to comprehend. The article ends by considering the status of religious convictions in comparison with convictions otherwise qualified
