  • Basic knowledge of cement a), Chemical composition of cement and hydration of clinker compounds Of the above figures, Alite has the most first hydrate reaction, therefore Alite contributes considerably to short term strength and the hydrate reaction completely finishes for a few months. While the hydrate reaction speed of belite is lower. As the result, the development of the short term strength is low, but it effects the long term strength. Alite reaction with water is the most activity, and interstitial material is also high reaction with water.(see figure 1)...

  • The ribbon itself forms an abstract letter ‘W’ (for World) that changes colour from pink through blue into a green that represents a green economy. The person’s position in the ribbon is where the colour incidentally transitions into green, signifying that people – you – are central to a functional green economy and thus it must include you. The light green part of the ribbon curves into a slight horizon of the earth.

  • The voltage of a battery is given by its open-circuit voltage (OCV) and overvoltages occurring due to diffusion processes, electrochemical reactions, and ohmic resistances. Because of these overvoltages, the cell voltage is always above the OCV during charging and it is always below the OCV during discharging. The battery voltage during discharging can be expressed in a first-order approximation according to the following equation:

  • The prediction of ship hydrodynamic performance can be broken down into the general areas of resistance and propulsion, seakeeping, manoeuvring. Propeller flows and propeller design can be seen as a subtopic of resistance and propulsion, but it is so important and features special techniques that it is treated as a separate topic in its own right. Morgan and Lin (1998) give a good short introduction to the historical development of these techniques to the state of the art in the late 1990s.

  • In addition, we only provide data at maturities where we think the curve can be fitted so that it is stable and meaningful. Instability arises when small movements in bond prices lead to unrealistically large moves in the estimated yield curves, essentially because there is not enough information from observed prices at a given maturity to allow us to fit that segment of the curve. This is usually a problem at short maturities where we require more information because we expect the short end of the yield curve to exhibit the greatest amount of structure.
