Globalization activity

The global activities of DuPont Films are discussed with reference to commercial strategies for profitable growth and by the integration of business and environmental initiatives. The Petretec chemical recycling process for polyester film is briefly described, and details are included of investments.

Several examples showing the effects of adatoms on activity and selectivity of a given catalytic reaction were observed. In most cases, this effect can be rationalized as a selective poisoning of undesirable sites. Usually, the presence of adatoms leads to a simultaneous decrease of the global activity and to a significant increase of selectivities in favor of the desired products. We describe here two examples. 

The total activity in the sample decreases with time following a curve that represents the superimposed activities of each radionuclei present. This global activity generally does not allow identification of the elements that have been formed. 

Modeling Arctic ecosystems as a result of anthropogenic impacts. Anthropogenic influence in the Arctic Basin and on adjacent territories is connected with local, regional, and global activities. Therefore, it is necessary to construct models/ scenarios that simulate ... 

The aim of the paper was to demonstrate the current state of research and development in the field of nanocelluloses on the basis of selected examples. The extraordinary supramolecular nanofiber network structure and the resulting valuable properties have led to a real challenge and extensive global activity. It is the intention of this work to broaden knowledge in this subject area... 

One more comment seems necessary. The Arrhenius expression [Eq. (32)] is commonly used to describe the rates of nonelementary reactions including several steps. In this case, the measured value of A is the apparent (global) activation energy, which is the resultant of sums and differences (with some coefficients) of activation energies of elementary steps whose rates contribute to the global rate (108). In our model approach, we calculate A for elementary steps only. Thus, there is no direct and simple way to compare our calculated barriers with the apparent barriers of nonelementary processes. This is particularly true for energy estimates made from the thermal-stability thresholds of chemisorbed species. 

Apart from his outstanding scientific achievements, his concern for polymer education, cooperative global activities at individual, group and institutional levels have produced excellent results and many have benefited from his efforts.

The premixed methanol flame [11, 12] does not show the Swan bands of C2, which are prominent in a methane flame [13]. The base of the flame shows strong emission from excited formaldehyde and further up the flame emission from OH and CH occurs. The burning velocity of a stoichiometric methanol—air flame [12] is about 45 cm. sec", and the global activation energy and global order are 43—47 kcal. mole" and unity, respectively [14(a)]. 

Methyl nitrite burns vigorously with oxygen at atmospheric pressure giving a very fast flame. It will also support a very feeble, slow self-decomposition flame [122—124]. The latter is orange-red and the burning velocity [125], relative to the unburnt gas at 18 °C, is about 3.5 cm.sec , while the global activation energy [126] is 37.5 kcal.mole . The final products of the flame are represented by the stoichiometric equation... 

Flame velocities of and temperatures in nitromethane flames supported by oxygen have been measured. The global activation energy is surprisingly low, viz. 10—16 kcal. mole", depending on the fuel/oxygen ratio [126].
