Study on behaviour of concrete added with different length of bamboo fibres

Nowadays, concrete is highly contributed in the construction works for its various advantages such as low cost, availability, fire resistance and others. Generally, concrete is high in compressive strength but relatively low in tensile strength. Steel is the mostly used for the reinforcement of concrete due to its high tensile strength. Alternate materials such as fibres are used to increase the tensile strength of the concrete. Bamboo is natural, cheap and readily available material. Most importantly, bamboo has a high tensile strength. This research is aimed at studying the performance of concrete with bamboo fibres as additives in it. The objective of this research was to experiment the structural behaviour of bamboo fibres reinforced concrete (BFRC) with various length of bamboo fibres as additives. In this paper, 2% of bamboo fibres by volume of the concrete with the length of 40mm and 60mm are added into concrete and compare with the plain concrete which act as the control specimen. 2 tests are tested which are the cube compression test and flexural test. From the test result has shown that the compressive strength of different length of BFRC is lower as compared to the controlled cube specimen. For flexural strength, the 40mm BFRC is the most optimum length as it has shown the almost similar strength with the controlled beam specimen. The flexural strength for the 60mm BFRC is slightly lower than that of the controlled beam specimen

The Mass-Action-Law Based GPS Concept for Bio-Informatics

The unified theory of dose and effect, as indicated by the median-effect equation for single and multiple entities and for the first and higher order kinetic/dynamic, has been established by T.C. Chou and it is based on the physical/chemical principle of the mass-action law (_J. Theor. Biol._ 59: 253-276, 1976; _Pharmacological Rev._ 58: 621-681, 2006). Rearrangements of the median-effect equation lead to Michaelis-Menten, Hill, Scatchard, and Henderson-Hasselbalch equations. The “median” serves as the “universal reference point” and the “common link” for the relationship of all entities at all dynamic orders, and is also the “harmonic mean” of kinetic dissociation constants. Over 300 mechanism-specific equations have been derived and published using the mathematical induction-deduction process. These equations can be deduced into several general equations, including the median-mediated whole/part equation, combination index theorem, isobologram equation, and polygonogram. It is proven that “dose” and “effect” are interchangeable, thus, “substance” and “function” are interchangeable, which leads to “the-unity theory” in philosophical context. Based on the mass-action law, the fundamental conceptual claim is that “one can draw a specific cure for only two data points”, if they are determined accurately. Furthermore, instead of drawing an empirical curve for data-fitting, we can now use the data points to fit the median-effect principle of the mass-action law by automated computer simulation. This small kill has far reaching consequences in biomedical sciences including small size experimentation, efficient experimental design and data interpretation, efficiency in drug discoveries, quantifying/simulating synergism in drug combinations, assessing low-dose risk of carcinogens, toxic substances or radiation, and conserving laboratory animals’ lives. For the “combination index” alone, the theory has been cited in over 345 different biomedical journals, based on the Thompson-ISI Web search, indicating broad applications
