with empirical slip models to cope with unsteady and non-uniform flows. Both conventional well tests include a deliberate disturbance to the production to determine the dynamic characteristics of a well. Moreover, these traditional routine well testing

difference more than 100 °C) and their physical structure showed a strong dependence on the thermal pre-treatment (thermal history). That was explained as a consequence of a molecular symmetry disturbance caused by the presence of alkyl chains in the

dimension change curves show distinct linear regions with an inflection at Tg . The mT-TM technique is useful for extracting thermal expansion coefficient information and Tg measurement with minimal disturbance of the material, in contrast to modulated

.15 have not been used to calculate its activation energy because the disturbance due to the subjectivity in the base line selection. The final result of activation energy is shown in Fig. 7 which is consistent with the previous models

a miniature humidity vessel, using 50 μL of water and tested at 25 °C. Because of the high humidity in the vessel, the data acquisition began soon after the vessel was closed and loaded into the measuring position; therefore some disturbances were

limit heat losses to the ambient and to protect the calorimeters from external disturbances, the whole device is placed in a 50-mm insulation of extruded polystyrene with a thermal conductivity of about 0.04 W m −1 K −1 . Four small heat

organisms that consume them, including people. In polluted areas, exposure of fish to xenobiotics leads to interactions between these chemicals and biological systems, which lead to biochemical disturbances. Most of the metals in organisms accumulate in

Introduction The depletion of natural resources, climate changes, and ecological balance disturbance as a result of human industrial activities are among the main problems of the day. These problems put questions for the

profiles of ROI 2 and ROI 3 seemed to be smoother compared to the profile of ROI 1. These results demonstrate that the HSM light intensity profile is strongly affected by the ROI sample location; the effect of noise and disturbances to the profile could be

implications in SOM permanence which can directly affect key issues related with climate change such as carbon sequestration or the vulnerability of current SOM stocks to disturbance [ 4 – 6 ]. Due to the heterogeneous nature of SOM, quantifying its quality has
