ical coupling factor to realize the required bandwidth of the PCS duplexer. So, the SAW duplexer for the PCS with the only steeper characteristics has been developed to eke out its insufficient temperature stability. The PCS duplexers consisting of FBAR (film bulk acoustic resonator) have also been designed as another approach, but their temperature characteristics are not thorough. In this pap...

During the past decades, Ocean Bottom Seismometers (OBS) have played a key role in permanent seismic activity monitoring at sea as well as allowing a better understating of the earth interior. Data collected by the instrument can provide information on the ocean bottom sub-layers down to a depth of 40 km beneath the ocean floor. The accuracy of the results directly depends on the temperature st...

Several diesters were prepared from commercially available oleic acid and common organic acids. The key step in the three step synthesis of oleochemical diesters entails a ring opening esterification of alkyl 9,10epoxyoctadecanoates (alkyl: propyl, isopropyl, octyl, 2ethylhexyl) using propionic and octanoic acids without the need for either solvent or catalyst. Each synthetic diester was evalua...

Thermal stability studies on some metal soaps of Hura crepitans seed oil prepared by metathesis in aqueous alcohol solution were carried out. The kinetics of the decomposition was studied thermogravimetrically in the temperature range 160 – 200 C. The values of the rate constant are of the order 10min and temperature-dependent. The enthalpy of activation (∆H) of the initial stage of decompositi...

Temperature is a universe and significant data in production and scientific experiment, effective measurement and control of the temperature are widely applied in every part of national economy. Therefore, temperature control has great significance; relevant requirements regarding temperature control are also higher and higher. Temperature command system for animal house is a complex system wit...

efficiency of enzymes which are used in industrial or environmental applications is highly dependent on their thermal stability. in this study, the stability of dfpase has been evaluated after introducing disulfide bonds to the structure. the results obtained from a series of protein design software were subjected to molecular dynamics simulation at different temperature to test the performance...

roasting has considerable effects on the quality of cream made of nuts. in this study, the roasting conditions of walnut kernels were optimized based on the stability parameters of the produced cream. temperatures of 100-150°c for 10-30 minutes were used to roast walnut kernels. the amount of oil separation, peroxide, acidity and thiobarbituric acid values of the cream, as well as color paramet...

A numerical shooting method for performing linear stability analyses of travelling waves is described and applied to the problem of freely propagating planar premixed flames. Previous linear stability analyses of premixed flames either employ high activation temperature asymptotics or have been performed numerically with finite activation temperature, but either for unit Lewis numbers (which ig...

Order(N) Tight-Binding Molecular Dynamics (TBMD) simulations are performed to investigate the thermal stability of (10, 10) metallic Single-Walled Carbon Nanotubes (SWCNT). Periodic boundary conditions (PBC) are applied in axial direction. Velocity Verlet algorithm along with the canonical ensemble molecular dynamics (NVT) is used to simulate the tubes at the targeted temperatures. The effects ...

This paper presents a series of structural modifications of epoxidized ricinoleic acid for biolubricant to improve the cold flow behavior and oxidation stability of vegetable oils through measurement of pour point (PP) and oxidation onset temperature (OT) and signal maximum temperature (SMT) of each synthetic compound. The results showed that butyl 10,12-dihydroxy-9-behenoxystearate with bulky ...
