Versus mechanism

Factors that enter into any economic analysis of handhng-warehousing systems are (1) expected mechanical and economic life of the system (2) annual maintenance cost (3) capital requirements and expected return on investment (4) building-construction cost and land v ue (5) detailed analysis of each work position (to determine trade-offs of labor and equipment expected future costs and availability of labor are important) (6) relation of system control and personnel used in system (trade-offs of people versus mechanical control) (7) type of information system (computerized or manual) and (8) expected changed in product, container, unit pallet loads, and customer preferences during the life of the system. 

I A 66 and 6 good ratio of price versus mechanical performances and fatigue resistance heat and cold behaviours friction behaviour (coefficient and wear) resistance to oil products and solvents very high impact strength of special grades. 

Good ratios for cost versus mechanical and electrical properties fair creep resistance at room temperature low moisture absorption fair heat and cold behaviours moisture and hot-water resistances low shrinkage.

Other important issues such as varietal or geographical origin, method of agronomical production (harvesting by hand-picking versus mechanical shaker), system of oil extraction (stone mill versus hammer crusher), come under the banner of fraud. 

Changes during storage in the moisture permeability of cellulose acetate films used to effect controlled release (Fig. 173) were predicted from changes in mechanical properties of the films.705 The mechanical properties measured were relaxation time versus mechanical stress. 

It is impossible to arrive at generalized guidelines at the present time regarding the technoeconomics of steam compression by thermocompression (e.g., steam jet ejectors) versus mechanical recompression for steam-drying plants. The costs of installation of such systems are such that they should be considered only for large-scale continuous steam dryers, that is, those with evaporation capacities of 100 ton/day or higher. The steam compressors for such service are expected to cost over 500,000 (1990 estimate for North America). To this cost, one must add the costs of spares and maintenance.

The influence of the microfabrication method on the adhesion is clearly visible from the comparison of etched stainless steel versus mechanically fabricated rectangular microchannels in Figure 5. A sol-gel coating of the different microstructures was performed by Kreuder et al. (2011) yielding alumina layers with a thickness of roughly 2 pm. 

The direct comparison between the two combined systems (Double Bed versus Mechanical Mixture) clearly shows that the mechanical mixture of SCR and PGM powders entails the occurrence of interactions between the activities of the two catalysts, as the SCR reaction products can react over the PGM catalyst and vice versa. Such an interaction is not possible in the Double Bed configuration, wherein the two catalysts are segregated. A similar picture was observed by Long et al. [39] who studied a noble metal-promoted Fe-ZSM-5 for Selective Catalytic Oxidation of NH3. Long et al. [39] attributed the reduced N2O and NOx production to the SCR features of the combined catalyst N2O and NO generated by oxidation over the noble metal can be indeed further reduced to N2 by unreacted ammonia, thus improving simultaneously ammonia conversion and N2 selectivity. 

As we anticipated, we decided to collect views of science, technology, woman and man scientist by, women and men fliemselves, university students enrolled in Engineering, considered as young researchers potentially devoted to science and technology. Two specializations were chosen, with different gender ratio as mentioned above Biomedical Engineering versus Mechanical Engineering.
