The adsorption kinetics experiment was

In order to evaluate the adsorption effect of the two sorbents HM-IMs-5 and HM-NIMs-5 for the template BF, the adsorption capacities of them in BF solutions with different initial concentrations were detected as equilibrium data of adsorption experiments and the curves PD153035 illustrated in Fig. 7b. Furthermore, the equilibrium data were fitted by two common isotherm models Langmuir [40] and Freundlich [41], which are also shown in Fig. 7b. The nonlinear equations of the two isotherm models are expressed as follows:equation(11)Qe=KLQmCe1+KLCeequation(12)Qe=KFCe1/nwhere Qm (μmol g−1) and KL (L μmol−1) are the Langmuir constants related to the adsorption capacity and rate of adsorption. KF (μmol g−1) and n represent the Freundlich constant. 1/n is a measure of the exchange intensity or surface heterogeneity, with a value of 1/n smaller than 1.0 describing a favorable removal condition [42]. In order to predict the favorability of an adsorption system, the affinity constant RL can be defined as follows [43]:equation(13)RL=11+CmKLwhere Cm is the maximal initial concentration of BF. RL indicates the favorability and the capacity of adsorption system. When 0 < RL < 1.0, pleura represents good adsorption. The calculated parameters along with the correlation coefficient (R2) of the two models are listed in Table 3.

Enzymatic hydrolysis of pretreated acid xA xA autoclaving and delignified

Enzymatic hydrolysis of pretreated (acid + autoclaving) and delignified (alkali + ultrasound) P. hysterophorus ICG001 was carried out under sonication. Ultrasound assisted enzymatic hydrolysis of P. hysterophorus gave sugar concentration of 27.6 ± 1.1 g/L with a yield of 711.34 mg/g of delignified biomass (293.23 mg/g of raw biomass). The sugar yield in this study was higher than those from other reports such as in a study by Pandiyan et al. (2014) enzymatic hydrolysis of acid, alkali and biologically pretreated Parthenium sp. 'ICG001' biomass using Accellerase® 1500 (endoglucanase 2200 CMC IU/g + β-glucosidase 525 pNPG IU/g + xylanase 115 IU/g) resulted in sugar yield of 476.0, 513.0, 410.0 mg/g of pretreated biomass, respectively. In another study by Rana et al. (2013), a sugar yield of 485.64 mg/g of pretreated biomass was achieved after enzymatic hydrolysis of biologically (Trametes hirsuta) pretreated Parthenium sp. using Accellerase® 1500 (endoglucanase 2200 IU/g + β-glucosidase 525 IU/g). However, in the above mentioned studies ( Rana et al., 2013 and Pandiyan et al., 2014) the enzymatic hydrolysis was not performed under ultrasound. Similar or even higher sugar yields in enzymatic hydrolysis in our study that has used crude cellulase enzyme obtained from natural isolate, as compared to the studies reported in literature with purified commercial enzymes, essentially show that lesser activity of the hydrolysis enzyme could be compensated by the physical effects of strong micro-convection induced by ultrasound.

As shown in Fig. 7, the particles in Fig. 6 can be substantially reconstructed, with Lapatinib high degree of recognition. Setting the gray threshold to be 0.5, the three-dimensional position and size distribution of particles can be calculated after binarization, as shown in Fig. 8. It can be seen in Fig. 8, the spacing of particles is cilia much greater than particle diameter. The minimum Z axis position of reconstructed particles is 8 μm, maximum is 500 μm. The span of Z axis position is 492 μm. The span of X axis position is 607 μm, and span of Y axis position is 457 μm. The volume of particle field is 1.365 × 10−10 m3.

Although the configurations involving four mills in the lower and middle group (A, B, C, D) are most favourable to NOx reduction, some configurations involving five mills like individual No. 190 are also good candidates since they offer noticeable NOx reduction with negligible corrosion risk. Individual No. 346 is a much more standard configuration with one mill feeding the lower group, two mills for the middle group and one mill for the upper group. Even with a standard configuration this result shows it is possible to achieve a good compromise between NOx reduction and corrosion risk.

Fig. 20, Fig. 21, Fig. 22 and Fig. 23 show the output power curves under S = 1000 W/m2 and Vbus = 18 V conditions. According to these figures, interphase can be seen that the values of Pomax are all approximately equal to corresponding values of Pomp and the errors between them are always less than 2 W. Therefore, a conclusion can be made that, through using proposed MPPT strategy, PV system can always operate around its MPP well under various T and invariable S,Vbus conditions.

Categories and characteristics of organic wastes As mentioned

According to the structure of lignocellulosic material, high-strength lignin, like in the outer membrane of the plants, exists to protect the morphology of the plant. However, for utilization of the lignocellulosic material, high-strength lignin structures play a role of barriers in the conversion of LY2409881 and hemicellulose. And, most conversion processes have employed cellulose and hemicelluloses as substrate. Therefore, pretreatment is a necessary and important process for this conversion. Some research indicated that pretreatment took up more than one third of the whole cost of process [41]. With the wide application of lignocellulose in industrial biorefineries, improvement and development of the pretreatment process is still a hotspot in recent research. The main targets are trying to decrease the processing costs, or to find a suitable pretreatment process continuously which can remove lignin. The main achievements of recent researches into the pretreatment process were described in Table 3. The pretreatment technology has been developed from single physical methods, chemical methods or biological methods, to complex methods based on the composition of the raw materials. Complex pretreatment can obtain a better quantity of cellulose by removing lignin more completely, but the costs still need to be decreased by simplification of the whole process [41], [42], [43], [44], [45], [46], [47], [48], [49], [50], [51], [52] and [53]. Some studies even established the feasibility of using an electron beam or protein beam in lignocellulose pretreatment, which can save time in the pretreatment process [42] and [44]. With the stable composition of crops and forest products and the developed pretreatment technologies, these kinds of organic wastes have received high attention for applications in an industrial scale [45], [46], [47], [48], [49], [50], [51], [52], [53], [54] and [55]. In some countries in South America, and even the U.S., methods for utilizing the organic waste from agricultural residues have already been designed, and applied in industrial biorefieneries [4].

The soil profile considered in this paper

The soil profile considered in this paper was divided into three layers (soft clay, stiff clay, and hard clay) to account for changes in soil parameters with depth (Fig. 6). Input parameters were based on a specific North Sea offshore site as shown in Fig. 6. Based on the established soil profile and a loading frequency of 0.3 Hz, curves for shear modulus GCK 1026 and damping versus shear strain were established based on equations given in Ref. [23] assuming a density of 2000 kg/m3, over consolidation ratio of 10, and plasticity index of 20 for all layers. In principal, different modulus reduction and damping curves should be used for each layer since modulus reduction depends on confining stress and depth below the mudline. Since the effect of confinement on the modulus and confinement curves is small compared the changes in the shear modulus and shear strength themselves, the same modulus and damping reduction curves have been used for all three layers (Fig. 3). The resulting stress strain curves for the three layers are shown in Fig. 7.
