The polyimides were easily soluble in polar organic solvents and even in less polar solvents and showed high thermal stability, with initial decomposition temperature being above 420 °C. Monte Carlo method was used to calculate conformational rigidity parameters of these polyimides. Some physical properties such as solubility, glass transition temperature and initial decomposition temperature were investigated and compared with those of related polyimides which did not contain any pendant groups based on the same dianhydrides and a diamine without pendant phenolic group. All data were discussed in relation to the rigidity of the chain.

The results indicate that the deep clay shale of this region is characterized by high density, high mechanical strength, low deformation and strong brittleness. More specifically, according to the tests, because of their relative small particle size, the carbonate grains of clay rocks in this region are distributed more uniformly, and the average clay mineral content is comparatively low, as a result, the deep clay shale of this region are featured by large internal friction angle and high mechanical strength.

Nondestructive testing (NDT) was carried out using impact rebound hammer (IRH) techniques to establish a correlation between the compressive strengths and the rebound number. The local curve for measuring strength of the regression method is set up and its superiority is proved. The rebound method presented is simple, quick, and reliable and covers wide ranges of concrete strengths. The rebound method can be easily applied to concrete specimens as well as existing concrete structures. The final results were compared with previous ones from the literature and also with actual results obtained from samples extracted from existing structures.

B. (1984) J. Biol. Chem. 259, 3337-3342). Furthermore, binding, but not processing, was observed in the presence of an uncoupler. Binding was insensitive to temperature and was completed within 2.5 min at 0 degrees C. The role of binding in the overall process of import of the precursor is now further characterized. The precursor form, bound either in the presence of an uncoupler or at 0 degrees C, was sensitive to trypsin suggesting that binding occurs on the mitochondrial outer membrane. Saturation of binding was observed with a limited amount of mitochondria and an excess of in vitro translated rat liver proteins indicating that there is a finite number of binding sites. Furthermore, when the precursor was prebound to mitochondria at 0 degrees C for 5 min, the precursor was processed to the mature size and the rate of processing was independent of the volume of reaction mixture. In contrast, the rate of processing of unbound precursor was dependent on reaction volume. These results strongly suggest that binding of the precursor of malate dehydrogenase to the mitochondrial outer membrane is an intermediate step in its import.

These methods produce a structural solutions that satisfies the equilibrium of forces and compatibility of deformations at all joints and supports. If a structure is highly indeterminate, an exact analysis can be time consuming. For continuous beam the innovative approximate method gives nearly accurate results. This method is based on relative deformation coefficient. In this paper parametric study for two span continuous beam with the concept of innovative approximate method for continuous beam is performed. From the study one can prepare charts for finding out Relative deformation coefficient. By obtaining this coefficient, moment for continuous beam can be find out very easily and nearly accurately.

The cement mortar mixes in proportion of 1:3 and 1:6 (cement: sand), which are the mixes usually adopted in various construction activities. The water/cement ratio (W/C) and sand ratio were kept constant for all mixes. The basic material testing was carried out before casting of cubes. Sand was replaced by sand stone dust of 0%, 25%, and 50% by weight of sand. The compressive strength of mortar checked at 3, 7, and 28 days of interval. The result showed that the partially replacement of SSD with Sand up to 50% replacement of SSD give reliable result for compressive strength.

Many precise methods of analysis have been well documented in the literature for structural analysis. Computer programs provide results with good cost and time efficiency. The main problem is that structural engineers are using these software’s as black box and gross errors are left undetected. This problem can be overcome by using fast and efficient methods which yield results which are approximate and acceptable. These methods are called approximate methods and they have been used successfully for the analysis of the structures. An attempt to give overview of such approximate method for the solution of continuous beam is briefly done in this paper. This paper also intends to compare this approximate method of structural analysis to the values obtained from classical method. For practical purposes approximate solution is worked out using this ap...

The choice between statically determinate and statically indeterminate structure depends on to largely the purpose for which a particular structure is required. These days, practically all major buildings are framed structures. Rigid jointed reinforced concrete frames are mostly used for High-Rise buildings, industrial structures, multilevel parking structures etc. The rigid High- rise building frames made with beam-column joints can resist bending moment, shear and axial forces, thus resulting in a highly indeterminate structure. Analysis of frame is possible through Kani‟s method or matrix methods, but solution by iteration or equation solving or matrix inversion process is tedious and time consuming for several loading cases. For quick analysis, design engineers use the approximate methods of analys...

Most countries abroad have abandoned this practice in favor of reclaiming of waste land. It has become necessary to develop strategies ofland re-use for completed landfills to improve environmental profile. This dumping site does not have enough strength to take load of structure to be built on it. In this research a strategy is developed for stabilization of such municipal dumping ground for reuse such land. Fly ash and hydrated lime is mixed in dumping ground at various proportions to improve strength of ground. This paper presents analysis of results obtained from experimental investigation done on stabilized dump. The strength of dump is measured usingDynamic Cone Penetrometer (DCP) Test. Use of Dynamic cone penetrometer is faster and easier way to determine the strength of stabilized dump.

The use of Stabilizing agent, for sub such as cohesion and improvement in cohesion leads to strengthening of embankment. This will ultimately lower down the road construction cost. This paper specifically addresses about soil stabilizing agent which are used to stabilize weaker soil to improve subgrade quality. In this paper review on use of different stabilizing agents such as lime, fly ash, cement, rice husk, geo stabilizing agent for application for stabiliz 1. Introduction Geotechnical properties of problematic soils such as soft fine various methods. The problematic soil is removed and replaced by a good quality material or treated using mechanical and/or chemical stabilization. properties of the problematic soils (such as strength and the stiffness) by treating it in situ. These methods include densifying treatments (such as compaction or preloading), pore water (such as dewatering or electro-osmosis), the bonding of soil particles (by ground freezing, grouting, and chemical stabilization), and use of reinforcing elements (such as geotextiles and stone columns) (William Powrie, 1997). In Germany, Vosteen (1998 & 1999) reported that the use of cement or lime for the stabilization of pavement bases (during the past few decades) was investigated and developed into practical construction procedures. These practical procedures have been im for road and traffic. Fly ash-soil stabilization for road construction is applied in USA, Japan, Scandinavian countries, and some other countries like India. In Germany, fly ash applied and there are no German recommendations and regulations for soil stabilization using fly ash. The Engineers are often faced with the problem of constructing roadbeds on or with soils (especially soft clayey and expansive soils).These problematic soils do not possess enough strength to support the wheel loads upon them either in construction or during the service life of the pavement. These soils must be, therefore, treated to provide a stable sub-grade or a working platf this is soil stabilization. The soil stabilization includes both physical stabilization [such as dynamic compaction] and chemical stabilization [such as mixing with cement, fly ash, Tests Division, Geotechnical Section, Indiana, 2002). Chemical stabilization involves mixing chemical additives (binding agents) with natural soils to remove moisture and improve strength properties of the soi agent in the treatment process is either reinforcing of the bounds between the particles or filling of the pore spaces. Most of these chemical stabilizing agents are not available in Egypt, ex well-known. The chemical stabilizing agents are relatively expensive compared with other methods of stabilization, so that the soil stabilization technique is an open the near future (Egyptian Code, 1995). The quality of the sub-grade soil used in pavement applications is classified into 5 very stiff, and hard sub-grade) depending on unconfined compressive strength values (Das, 1994). The quality the sub-grade soil used in pavement applications is classified into 5 excellent) depending on the CBR values (Bowles, 1992).
