BACKGROUND: Opisthorchis viverrini is a food-borne trematode species that might give rise to biliary diseases and the fatal cholangiocarcinoma.In Lao PDR, an estimated 2.5 million individuals are infected with O.viverrini, but epidemiological studies are scarce and the spatial distribution of infection remains to be determined.Our aim was to map th
Abstract Multi-stable structures attract great interest because they possess special energy landscapes with domains of attraction around the stable states.Consequently, multi-stable structures have the potential to achieve prescribed reconfiguration with only a few lightweight actuators (such as shape-memory alloy springs), and do not need constant
Cyflumetofen is a new type of acaricide with high efficiency and low residue.In this work, the compound was characterized BUTTON DOWNS by infrared absorption (IR), ultraviolet absorption (UV) and mass spectrometry, as well as nuclear magnetic resonance spectroscopy (1H NMR, 13C NMR, DEPT, 1H-1H COSY, 1H-13C HSQC and 1H-13C HMBC).The characteristic
The underground mining environment is currently based on technology that uses mainly analogue sensors in machine and equipment control systems.The primary machine performing the most important functions in a mining system is the powered roof support.In order for it to work properly, it is important that it achieves the required power.To ensure this
