Introduction: Third molars (M3) remaining impacted in Class II malocclusion characterised with sagittal mandibular deficiency is a high probability.The null hypothesis of this study is that mesioangular M3s changes position through the eruption way in Class II malocclusion treatment requiring moderate anchorage with four first premolars extraction.

One of the main directions in construction material science is the development of next generation concrete that is ultra-dense, high-strength, ultra-porous, high heat efficient, extra corrosion-resistant.Selection of such direction is caused by extreme operational impacts on the concrete, namely: continuously increasing load on the concrete and var

In order to identify the natural frequency of ship propulsion shafting under the running Stick condition, a multi-method approach that combines Duffing Oscillator, harmonic wavelet packet transform, and probability density function is proposed.An experimental investigation on the natural frequency of running propulsion shafting is conducted on the

Hibernation, an evolved survival trait among animals, enables them to endure frigid temperatures and food scarcity during the winter months, and it is a widespread phenomenon observed in mammals.The gut microbiota, a crucial component of animal nutrition and health, exhibits particularly dynamic interactions in hibernating mammals.This manuscript c
