European foulbrood disease caused by Melissoccocus plutonius which gram-positive bacterium that leads to larval deaths with its worldwide prevalence, paving the way for beehives die away over time. It causes economic losses in honey production. Bee breeding and production are economically pivotal Turkey, it is vital analyze prevalence of this disease. This study aims identify M. from honeycombs...

We predict planar Sb/Bi honeycomb to harbor a two-dimensional (2D) topological crystalline insulator (TCI) phase based on first-principles computations. Although buckled Sb and Bi honeycombs support 2D topological insulator (TI) phases, their structure becomes planar under tensile strain. The planar Sb/Bi honeycomb structure restores the mirror symmetry, and is shown to exhibit non-zero mirror ...

The reduction of global CO2 emissions requires cross-sectoral measures to reduce fossil energy consumptions and strengthen the expansion renewable sources. One element for this purpose are thermal storage systems. They enable, due their time-decoupled operation, increases in systemic efficiency flexibility various industrial power plant processes. In electricity heat sector such solutions alrea...

Abstract The equivalent parameters of hexagon aluminum honeycombs are work out with the theories sandwich plates in this paper. honeycomb plate reinforced by ring beam applied static load is simulated finite element model plates, which validated test. research results show that numerical calculation error less than 10% compared test results, acceptable for an engineering project, and mechanical...

The large difference between in-plane and out-of-plane mechanical properties limits the application of traditional composite honeycombs in submersibles. In this work, carbon fiber tube reinforced polymer (CTPC) which have lightweight characteristic high hydrostatic strength is designed manufactured. combination epoxy resin inhibits buckling failure improves bearing capacity tube. Resin binds tu...

Apis cerana Fab. is one of the popular honeybees species among beekeepers in Indonesia. This easy to care for and produces valuable honey products. Honey from A. abundantly available traditional modern markets The purpose this study was identify primary secondary metabolites produced by using FTIR-ATR Diamond spectroscopy. Twelve samples three provinces Java Island were used study. In general, ...
