When the short bypass around Green opens with much fanfare, downtown dries up faster than cement on the roadway. Businesses close, and the hospital becomes a clinic. Mayor Eva must decide whether to sell her historic store or close it. The Holey Moley Antique Mall seems less like a dream and more like a nightmare. While the road is progress to some, it seems to be leading Green toward a national trend - a town that is merely a shadow of itself. With the town going backward, Lois leans on her faith but is both intrigued and jealous when a fellow business owner comes up with a strategy to save Green. But can her plan rescue the town from the path it's on? 1. Language: English. Narrator: Tara Ochs. Audio sample: http://samples.audible.de/bk/adbl/024939/bk_adbl_024939_sample.mp3.

Future Trend in Supply Chain Practices in Cement Industry ab 49 EURO Supply Chain Engineering of Cement Industry
In recent years, the courses in chemistry have been considered extremely important for students desirous of pursuing basic science as well as technical education. Taking into consideration this trend, this book has been specially written for students who are interested in investigatory and innovative projects in chemistry. The unique feature of this book is that the basic, theory, procedure and conclusions for each project are given in comprehensive manner. In all 51 projects are included in this book from all the branches of chemistry viz. inorganic, organic, physical, analytical and general chemistry.some of them are: Antacid effectiveness analysis, Study of tea chemistry, study the foaming capacity of soaps, Study of constituents of brass and bronze, Preparation of potash alum from scrap aluminum, Extraction of essential oil from aniseed, preparation of pigments and poster paints using chemicals and reagents, Analysis of calcium, phosphate, chloride, magnesium and iron from bone ash, To Study the Setting of Cement, Comparative study and qualitative analysis of cold drinks, preparation of cuprammonium rayon threads from filter paper, Analysis of talcum powder etc.
Biomass incineration for the generation of heat and electricity has increased in recent years and this trend is expected to be continued. Ashes as inorganic residues from incineration contain nutrients, but also heavy metals and unburnt carbon. Bottom ashes with low levels of heavy metals are usually used as fertilizers in forests and on fields. Fly ashes are highly contaminated with heavy metals and must therefore be properly disposed of. In view of the rising amount of biomass ashes, this doctoral thesis analyzes different ways for the utilization of biomass ashes - especially heavy metal contaminated fly ashes. The following topics are part of the doctoral thesis: - Validation of the analytical method ICP-OES for determining the concentrations of Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Mg, Mn, Na, Ni, Pb, Sb, Sr, Ti, V, and Zn - Extraction experiments for the investigation of the mobility of heavy metals and nutrients - Experiments of the influence of fly ashes on plant growth - Air classification of fly ashes and investigation of the elemental concentrations in different grain sizes - Analysis of the possibility of using fly ashes as secondary material in the cement industry
Amidst the globalization trend and increasing economic integration in the Southeast and East Asian region, this book assesses the trade liberalization experience of the Philippines focusing on its impact on competition. It covers not only the overall manufacturing industry but also a case study of the cement industry where an alleged cartel is known to operate. From the fifties till the seventies, Philippine manufacturing received heavy protection from high tariffs, import controls and restrictions. Government-sanctioned monopolies and cartels were allowed along with price controls and entry regulations. In the 1980s up to the mid 1990s, substantial trade reforms were pursued leading to reduced industry protection. After more than twenty years of unilateral trade reforms, it is important to ask whether this has led to reduced market power and increased domestic competition. Are imports effective in disciplining an industry particularly those characterized by collusive behavior such as cement? What lessons can be drawn from Philippine experience? What policy suggestions can be made to improve competition and reap the benefits from opening-up markets?
Indian cement Industry is world second largest producer with immense growth opportunity has generated excitement among cement producers to adopt world class practices to sustain competitive advantage.The key challenges in front of Indian cement industry is to reduce cost and improve profitability.However in the year 2010 & 2011 the input cost has increased due to meteoric rise in fuel price.The hike in diesel and petrol has also forced industry to revise their road freight.In such situation only by controlling logistics cost will not improve the situation. In such case cement industry has to adopt an integrated approach towards managing the entire supply chain.Here in this research authors has clearly defined the kind of supply chain strategies to be adopted by this industry whose demand and supply pattern varies from season to season. The constraints of wagon availability during peak season,high overhead expenses,non-uniformity in tax structure and intense competition has triggered the need for "innovative supply chain practices".
This book focused on the initial surface absorption behavior of cement system modified with polymer and pozzolan in direct relation to mortar durability. Polymer additive namely Styrene Butadiene Rubber (SBR) and Styrene Acrylic Ester (SAE), as well as pozzolan additive namely Fly Ash (FA) and Silica Fume (SF) with different percentages of addition were used as a composite of OPC mortar with w/c ratio ranging from 0.3 to 0.5. Results showed that specimens with w/c of 0.5 absorbed the least water. It also showed that non-modified OPC mortar specimens absorbed more water compared to the modified composite specimens upon addition of polymer and pozzolan. Further analysis showed that specimens with 10% polymer content and 10% pozzolan content absorbed the least water in comparison to 5%, 7% polymer content and 20% and 30% pozzolan content. Above that, SAE and FA allow lesser absorption compared to SBR and SF. It can be concluded that the addition of 10% SAE and 10% FA composite can reduce initial surface absorption capacity of all 0.3, 0.4 and 0.5 w/c OPC mortar with validation from the trend of the strength development as they matured hence can potentially improve concrete durability.
Reinforced Cement Concrete (RCC) construction is a well-known form of building construction in Civil Engineering industry worldwide. But due to its weak performance during seismic events, this form is under revision or research. Steel moment resisting frame (SMRF) with deck slab is a new trend construction technique, which is attracting technocrats working in Structural Engineering field. High ductility and ease in modification and maintenance, makes them more popular as compared to RCC structure nowadays in earthquake prone areas. The energy dissipation capacity of the structure can be improved by installing energy dissipaters into the structures. The SMRF enhanced with passive energy dissipaters are investigated for earthquake response and energy dissipation capacity and an innovative approach of design of these systems is recommended in this research work. . The ten storied steel structure is analyzed by nonlinear time history analysis, with incremental dynamic loading of seven earthquake ground motion time history records, which are scaled to achieve a set of results and then compared with various possibilities.
The suitability of masonry mortar for various construction applications is dependent on some vital engineering properties and production cost. In majority of masonry formulations,ordinary portland cement(OPC) is the principal binding agent. However the current trend of cement cost in Ghana has rendered masonry mortar formulation quite expensive. Meanwhile in other parts of the world, different types of admixtures which are either chemical or mineral products are well known to improve mechanical and economical values of formulated mortars. In this study two available mineral admixtures namely clay pozzolana and limestone were used as partial replacement of OPC to formulate binary and ternary pastes and mortars. Some mechanical properties and aspect of durability studies were determined. The economic analysis of using mineral admixture in masonry mortar over plain mortar was studied. Test results indicated that the formulated paste and mortar showed appreciable mechanical properties. In accordance to the ASTM,both type M and type S mortar classes were produced which also presented a satisfactory economic advantages over plain mortars.
