In this paper, the authors present an idea to exploit low enthalpy geothermal energy in order to reduce street temperature fluctuations throughout the year and avoid ice formation during the winter season. The key aspect of the proposed system is that it is based on the exploitation of geothermal temperature gradients through materials with high thermal conductivity inserted into the ground, su...

To design an enzyme immunoassay-based method, the most important is conjugation of enzyme with antigens or antibodies and stability of labeled conjugate. In this study, human albumin was conjugated with horseradish peroxidase using periodate oxidation method. To stabilize biological activity and functional structure of different components of protein conjugate, special storage conditions are re...

The oxygen isotope composition of fossil fish teeth, a paleoupper ocean temperature proxy exceptionally resistant to diagenetic alteration, provides new insight on the evolution of the lowto middlelatitude thermal gradient between the middle Cretaceous climatic optimum and the cooler latest Cretaceous period. The new middle Cretaceous low to middle latitude thermal gradient agrees with that pre...

There is a continuous search for an alternative oxide material to the yttria-stabilized zirconia (7YSZ), which currently serves as the thermal barrier coating materials for turbine engines [1]. The new material should have low thermal conductivity, high temperature stability, and ferroelastic toughening as exhibited by the 7YSZ. Therefore in this study, the Y-Ta-Zr-O system was investigated. Th...
