as functions of hydrogen dilution and power. Figure 1a depicts the variation in these parameters for the radio frequency 共 rf 兲 power of 5 W and a hydrogen flow from 55 to 220 sccm. Adding more hydro- gen reduces the growth rate from ⬃ 1.6 to ⬃ 1.1 Å/s and increases the index of refraction from 1.75 to 1.79. Figure 1b shows the depo- sition rate and index of refraction as functions of rf power for the hydrogen flow rate of 165 sccm. An increase in the rf power from 5 to 20 W causes an increase in the growth rate from 1.2 to 2.1 Å/s and a slight increase in the index of refraction from 1.79 to 1.80. The bottom graph, Fig. 1c, shows the same parameters for the high- est hydrogen flow of 220 sccm and a large variation in rf power from 5 to 50 W. Over this power range, the deposition rate increases from 1.1 to 2.9 Å/s and the index of refraction increases slightly from 1.79 to 1.81, both with increasing power.

Factors affecting properties of fuel pellets from compaction of mixed biomass and waste plastics

Factors affecting properties of fuel pellets from compaction of mixed biomass and waste plastics

preheating temperature. Strong densified product and high density of the pellet were produced as shown in Figure 4 and Figure 5. The reason is that it takes fewer loads and makes soften natural binder (such as oil, starch, lignin or protein) during compaction process (Kaliyan and Morey, 2009; Chou, et al., 2009b). Higher preheating temperature makes soften fiber, decreases energy consumption and resistance between particles. These behavior makes particles binds easier as tested densified strength at preheating temperature of 25°C to 150°C by Grover and Mishra (1996). These results found that the strength of densified product was increased with the preheating temperature. However, particles may not be bonded at higher preheating temperature and higher moisture content. The reason is that moisture migrates to the bottom of material which effect to loose particle bonding during compression at lower part of pelletization and consequently less durability pellet is obtained. . Figure 3 showed that durability index was reduced as increasing the plastic volume. Pellet with plastic waste and corn stover ratio of 75:25 provides the lowest durability, while the highest durability index was found at 55:45 of mixed plastic and corn stover ratio. It can be explained that more plastic content decrease durability index at the same condition. In addition, corn stover has fiber, protein and lignin which can improve pellet durability. This means that pellet with high content of corn stover should have high durability index. Figure 4 shows that density was reduced with the increasing of plastic volume. The lowest density was found at 75:25 of mixed plastic and corn stover ratio, while the highest density was found at the mixed ratio of 55:45. At the

It appears that AeD-R and AeD-T able to produce effluent with better settling capability. However, the effluent supernatant of all aerobic digesters barely meet the local discharge standard of TSS concentration of 400 mg/L. After two hours of settling, the TSS remained in the effluent supernatant of AeD-R, AeD-M and AeD-T were 410 to 910 mg/L, 835 to 1590 mg/L and 315 to 740 mg/L, respectively. These values are much high than previous research reported only 150 to 250 mg/L TSS remained in the final effluent. This remarkable TSS removal may be caused by a higher MLVSS concentration as well as longer settling time.Besides that, the TSS and VSS removals (Fig. 3a, b and c) were less affected by inclined OLR which is coincided with COD removal aforementioned. The TSS removals for AeD-R, AeD-M and AeD-T were 85.5 to 94.8 %, 81.6 to 90.0 % and 86.9 to 94.9 %, respectively. Hence, higher OLR could be applied bcacause the aerobic digesters have not yet to reach its maximum operational limit.

A synthesis of marine sediment core 13 C data over the last 150 000 years

Culture experiments on planktonic foraminifera also reveal a strong dependence on the concentration of the carbonate ion, with a gradient of approximately −0.012‰/(µmol kg −1 ) for G. bulloides under constant DIC (Spero et al., 1997). Glacial carbonate concentration is de- pendent on the poorly constrained alkalinity inventory of the ocean, but a change of 30 to 80 µmol kg −1 is not implausible (Kohfeld et al., 2000), indicating an effect of the same order as glacial δ 13 C cycles. The effect of carbonate ion on benthic δ 13 C is not known. Increases in light availability have been found to increase δ 13 C in Globigerinoides sacculifer, leading Spero and Lea (1993) to propose that the correlation between shell size and δ 13 C is principally caused by the dependence of both growth rate and δ 13 C on ambient light levels. Fur- ther effects arise due to changes in the isotopic composition of carbon in the diet. Culture experiments indicate that δ 13 C in G. bulloides shell carbonate varies as δ 13 C in organic mat- ter in the ratio 0.084:1 (Spero and Lea, 1996). Finally, the planktonic δ 13 C signal can be distorted from a surface signal by secondary calcification in deeper, typically isotopically lighter, waters, as observed by Duplessy et al. (1981b) on G. sacculifer transferred to laboratory tanks.

agement, 0.61 and 0.45, respectively (52). Here, we also observed that long-term fertilization significantly increased the z values of fungi, which were 0.0704 in the fertilized plot and 0.0604 in the control plot. It has been proposed that N fertilization may affect fungal communities by altering plant C inputs (53). Thus, more internally heterogeneous patterns of plants under N addition may result in steeper spatial changes in fungal communities. In addi- tion, the difference in estimated z values in these two studies might be due to the different approaches used with different ecosystems. Here, we estimated the TARs of all fungi in bulk soil of grassland and used a microarray hybridization-based approach, which con- tains tens of thousands of functional gene markers so that many microbial populations and functional groups can be simultane- ously detected at the whole-community-wide scale (9). Thus, any direct comparison of z values with different methods would be difficult.

Experimental study and effects of the drying kinetics of stabilized earth bricks based on sugar cane molasses

Experimental study and effects of the drying kinetics of stabilized earth bricks based on sugar cane molasses

Linear drying shrinkage: The water required to mould the briquettes causes a shrinkage by desiccation during the drying of the material. Evaporation of water causes suction between soil particles and causes linear and volumetric shrinkage of the soil material. The following figures show the evolution of shrinkage as a function of time for oven drying at 100°C, 120°C, 150°C (figures 11, 12 and 13). From these figures, we can see that the rate of shrinkage is much higher during the first 48 hours of drying. It also shows that the addition of molasses at 10% reduces the linear drying shrinkage while at more than 15%, the linear drying shrinkage increases. Shrinkage is observed when the briquettes are dry. For briquettes with 20% molasses, the specimens dried at 150°C showed several microcracks. Drying induces by differential deformation of drying shrinkage between the core and the surface of the briquette a microcrack on the surface. The increase in shrinkage in briquettes stabilized with 15 and 20% molasses is a definite consequence of the chemical transformations that occur inside these briquettes. However, since the chemical components of molasses do not control all the contours of the reaction of the chemical components of molasses with those of the soil, the details of this phenomenon are not taken into account in this book. There is therefore an optimal amount of molasses beyond which there is an increase in shrinkage. Figures 14, 15 and 16 show the evolution of shrinkage as a function of time for oven drying at 120°C. From these figures, it appears that the addition of molasses increases the linear drying shrinkage. Linear shrinkage is higher for briquettes stabilized with 20% molasses. At this temperature. However, none of the bricks studied showed cracks. The shrinkages observed when the briquettes are dry are: At 100°C, shrinkage is greater for unstabilized briquettes depending on width and height. Depending on the length, briquettes stabilized at more than 15% have a higher shrinkage. The shrinkage observed when the briquettes are dry. The kinetics of the drying shrinkage is related to that of the water flow and depends on the drying conditions. It is possible to link the increase in drying shrinkage to the loss of mass of the briquettes. Due to planning constraints, drying campaigns at low temperatures could not be carried out (Figures 17, 18 and 19).

Effect of relative humidity on thermal degradation of Norway spruce (Picea abies) wood

Effect of relative humidity on thermal degradation of Norway spruce (Picea abies) wood

The rate of thermal degradation of wood as a function of relative humidity for setup temperatures of 150°C and 170°C is plotted in Fig. 4. The reaction rate was computed independently for every heat-bath treatment. At both setup temperatures, the rate of degradation increased, seemingly exponentially, with increasing relative humidity in the heating atmosphere. It is known that between 100°C and 200°C, heating of wood produces water vapor and noncom- bustible products such as carbon dioxide and carboxylic acids, mainly acetic acid. 6,7

A Critical Review on of 3D Printing Materials and Details of Materials used in FDM

A Critical Review on of 3D Printing Materials and Details of Materials used in FDM

The most important mechanical properties of ABS are impact resistance and toughness. A variety of modifications can be made to improve impact resistance, toughness, and heat resistance. The impact resistance can be amplified by increasing the proportions of polybutadiene in relation to styrene and also acrylonitrile, although this causes changes in other properties. Impact resistance does not fall off rapidly at lower temperatures. Stability under load is excellent with limited loads. Thus, by changing the proportions of its components, ABS can be prepared in different grades. Two major categories could be ABS for extrusion and ABS for injection moulding, then high and medium impact resistance. Generally ABS would have useful characteristics within a temperature range from −20 to 80 °C (−4 to 176 °F). [18]

The CRF will use Monte Carlo simulation techniques to optimise fitting of radiobiological parameters to the EORTC and START data sets. Parameter set validation will be performed using a separate data set of 250 patients from the Cambridge Breast IMRT trial. These patients would not have been included in the development of any of the previous models. All these patients will have reached 5 years follow up from completion of radiation treatment and will have both late normal tissue toxicity and quality of life 5-year follow up data available. Currently, there are 350 IMRT trial patients with 5 years of follow up (September 2010) and there will be an additional 150 patients by June 2011. This will give a total of 500 patient’s data to be used within both the development and validation of the radiobiological model (D7).
