that control the rheological behavior of a superplasicized cement paste and concrete. An optimum amount of soluble alkalis content exists and ranges between 0.4 and 0.6% of Na2Oeq in the cement. The rate of the naphthalene based superplasticizers’ adsorption on the cement particles and cement hydrates‚ which is influenced by these parameters‚ controls the loss of fluidity of the concrete. Moreover‚ this study has shown that concrete made with cements that have a low soluble alkali content not only lose

[pic] TAKEING THE MYSTERY OUT OF THE TXV The thermostatic expansion valve has been considered by some to be a mysterious and complex device. As a result‚ many valves are needlessly replaced when the cause of the system malfunction is not immediately recognized. Actually the thermostatic expansion valve performs only one very simple function. –it keeps the evaporator supplied with enough refrigerants to satisfy all load conditions. It is not a temperature control‚ suction pressure control

6. TREATMENT METHODS Screening‚ grit removal‚ flow equalization‚ sedimentation‚ or dissolved air flotation are used to reduce suspended solids (SS) load from sugar industry wastewater. Biological treatment includes aerobic and anaerobic process. Except biological methods‚ physico-chemical methods are also used for sugar industry wastewater treatment. 6.1 Biological methods Since‚ sugar industry wastewater contains mostly sugars and volatile fatty acids‚ which are easily biodegradable‚ therefore all

Figure 1 shows the structure of 2MBI‚ 2MBI-Au‚ 2MBI-Pd and 2MBI-Ni before and after structure optimization. The drawn 2MBI is presented in Figure 2a and the optimized structure of 2MBI is illustrated in Figure 2b. The most important lengths and angles of bonds for the optimized structure of 2MBI are reported in Table 1. In the optimized structure of 2MBI component‚ S-H‚ S-C‚ C-N bond lengths and the HSC‚ SCN‚ CNH‚ SCN(H) bond angles were 1.386A°‚ 1.667A°‚ 1.377A°‚ 93.291°‚ 125.921°‚ 126.521°‚ 120
