Fig. 8.7. The influence of powder morphology (configuration) on shock modification controlling initiation of reaction is shown by the thermal response of mixed Ni-Al powders of different morphologies. The preinitiation event shown in Fig. 8.5 is observed to be strongly influenced by morphology at fixed shoek condition. The eoarse-medium mixture shows the largest preinitiation event [91D01]. The data show mueh larger preinitiation events for the flaky and fine morphologies.

White and Oswald present two compnter programs in the report, which can be nsed to obtain estimates of the stmctnral response and the thermal response of a detonation flame arrester. However, they point ont that neither of the programs will reveal completely what is needed to design a snccesshil flame arrester snpport. The anthors also evalnated the USCG test procednre and present recommendations on how this test pro-cednre shonld be modified to improve it. 

All the aforementioned advantages and several additional features apply to ELP-based macromolecular carriers. First, ELP-based carriers are thermally responsive. Second, ELP is a biopolymer and therefore is nontoxic and biodegradable. Third, the gene-based synthesis of ELP allows the creation of genetic fusions with functional peptides and proteins, such as targeting sequences.

Instrument measurement response can often be important in the overall system response. The thermal response of a simple thermometer bulb, immersed in fluid, as shown in Fig. 2.6, is the result of a simple heat balance in which...

In the boreholes, which are placed at a parking lot, single U-pipes are installed. There is no back filling, but the holes are filled with ground water. The boreholes are drilled through 65 m of clayey soil and 135 m of shale. The thermal conductivity has been measured with a Thermal Response Test (TRT) to be approx. 2.8 W/m K. 

Before the calculation of performances, heating and cooling loads which can be covered by the Energy Pipe System are evaluated. Total amount of heating and cooling is 230 GJ and 75.6 GJ, respectively, and peak loads are 50 kW for heating. On the other hands, average effective thermal conductivity was measured by the on-site thermal response test and it was 2.2 W/(mK). 

For small-tube-rupture flows that simulated the flow from the single-ended rupture of up to 16 steam generator tubes in a PWR system initiated at the start of vessel refill, the core thermal response was strongly dependent on the magnitude... 

To understand the physical mechanisms of flow boiling crisis, simulated tests have been conducted to observe the hydraulic behavior of the coolant and to measure the thermal response of the heating surface. To do this, the simulation approaches of the entire CHF testing program are considered as follows. 

The problems related to the colloidal stability of amphiphilic polymers in water are reviewed by Aseyev, Tenhu, and Winnik in the first chapter of volume 196. The focus is on the derivatives of thermally responsive smart macromolecules - both on copolymers and homopolymers - which are present in a solution as stable micelles potentially having various applications. 

In the previous sections, we described the overall features of the heat-induced phase transition of neutral polymers in water and placed the phenomenon within the context of the general understanding of the temperature dependence of polymer solutions. We emphasised one of the characteristic features of thermally responsive polymers in water, namely their increased hydropho-bicity at elevated temperature, which can, in turn, cause coagulation and macroscopic phase separation. We noted also, that in order to circumvent this macroscopic event, polymer chemists have devised a number of routes to enhance the colloidal stability of neutral globules at elevated temperature by adjusting the properties of the particle-water interface. 

Novel thermally responsive polymeric nanoparticles that show high colloidal stability were prepared by Laukkanen et al. via emulsion polymerisation of VCL in the presence of the amphiphilic macromonomer cw-methoxy polyethylene oxide undecyl a-methacrylate (MAC11EO42) (Fig. 15) [177,178,182]. The macromonomer itself proved to be highly sur-...
