    AC conductivity: Figure 4.19(a) shows the frequency dependent electrical conductivity of PCL5 electrolyte. The result shows that AC conductivity changes with temperature. The AC conductivity of the PEO/CoCl2 electrolyte increases with temperature is given in Table 4.4, which is the common characteristic of disordered materials. An increase in ac conductivity with frequency and temperature indicates charge transported by hopping through the defect sites along the polymer chain [70]. Also the…

    3A.2.10 Robustness A method is robust if it is unaffected by small changes in operating conditions. To evaluate the robustness of developed analytical method few parameters were deliberately changed. The parameters included analysis at different temperatures viz. 250C and 300C, at 0.8 and 1.0 mL/min flow rate, using C18 columns from different manufacturers one from Qualisil BDS, USA (4.6 x 250 mm x5µ) and the other from LC-GC, India (4.6 x 250mm x5µ). Each of the three selected factors were…

    Solubility property of ozone is dependent on several extrinsic factors such as temperature, pressure, composition of the medium, pH, gas flow rate, etc. Henry’s law says that the pressure of the gas exerts above the liquid is directly proportional to the solubility of the ozone (Bablon et al., 1991). De Smedt et al. (2001) revealed that solubility of ozone is dependent on pH, temperature and type of additives of the aqueous solution. Levanov et al. (2008) found that solubility of ozone decreased…

    Abstract Thermo-mechanic treatment consists in utilization of two classic technological proceedings. This type of treatment was applied to the studied high-speed steel (HS2-9-1-8). The made tests wanted to establish the influence on the hardness and wear of the high-temperature thermo-mechanical treatment (HTTMT) applied to studied steel. The application of an additional plastic deformation (the deformation degree between 45 – 75%) influences positive the hardness and wear value. Being a HTTMT,…

    Heat stress may occur to human when the controlling means for internal temperature to their body starts to fail (Health and Safety Executive, 2013). There are different contributing factors to the heat stress such as temperature, amount of work performed in heat (ambient temperature), clothing worn at work and humidity. When somebody wears protective dress to perform heavy task in hot environment, can result the heat stress due to: restricting the evaporation of sweating; heat rise in body due…

    that diverts from a null expectation, defined by random use of thermal microclimates and passive exchange of heat with the environment (Akin, 2011; Kemp & Krockenberger, 2002;). In Biomimicry, through studying thermoregulation, human beings can apply nature’s techniques to architecture when designing buildings. Present temperature systems are using a lot of energy, especially to control heat and cooling loads. (Carpi 2010). Thermoregulatory mechanisms include passive thermoregulation and…
