Background Frontal sinus fractures, particularly anterior sinus fractures, are relatively common facial fractures.Many agree on the general principles of frontal fracture management; however, the optimal methods of reduction are still controversial.In this article, we suggest a simple reduction method using a subbrow incision as a treatment for iso
A bidirectional axial flow pump can realize bidirectional pumping, which has a wide application prospect in coastal low-head pumping stations and water jet propulsion systems.In this paper, a typical bidirectional axial flow pump is taken as the research object, and the hydraulic model of the bidirectional axial flow pump is manufactured.The Cardio
Aquaculture plays an important role in providing protein-rich foods, meeting the growing demand for fish.However, Vehicle Parts aquaculture is a potentially polluting activity, especially with regard to water pollution, due to the improper disposal of wastewater from the production process.Aquaculture wastewater is rich in nutrients (ammonia, nitra
A theoretical study of unsteady magnetohydrodynamic boundary layer stagnation point flow, heat and mass transfer of a second grade electrically-conducting nanofluid from a horizontal stretching sheet with thermal slip and second order slip velocity effects is presented.The Buongiorno formulation is employed for nanofluids and in addition the no-flu
Aims: To determine the prevalence, patterns of occurrence and variations of zygomatic Sleep air cell defects (ZACDs) using panoramic radiographs.Methods and Materials: Dental panoramic radiographs of 600 outpatients were examined to evaluate the variations and characteristics of ZACDs.Results: ZACDs were identified in 15 subjects out of 600, giving
