Mitigating thermal stratification in lakes/reservoirs through wind-powered air diffusers.

Thermal stratification can cause various water quality issues in large water bodies. To address this, a new wind-powered artificial mixing system is designed and experimentally tested for various Savonius rotor combinations (three-stage and four-stage rotors). These turbines directly utilize wind energy to draw air into the water column for aeration, bypassing the need for electrical conversion.

Results of Allografts and Synthetic Grafts in Humeral Simple Bone Cysts.

Purpose Of The Study: Simple bone cysts (SBCs) are the most common benign bone lesions in childhood. There are many different methods in the treatment of SBCs. There is no consensus on which method to use in the treatment.

How successful is synthetic graft treatment for children with pathological hip fractures?

Purpose: To determine whether synthetic grafts are a satisfactory treatment option for pathological proximal femoral fractures in children.

Methods: Paediatric patients treated for pathological fractures of the proximal femur between 2013 and 2020 were evaluated retrospectively. 17 patients with a mean age of 10.

Visitor behavior during hospital inpatient visitation.

Introduction: The common target audience of the current guidelines for the prevention of healthcare-associated infections is represented by healthcare workers. Behavioral protocols for visitors and caregivers that aim to prevent healthcare-associated infections are still not available. The aim of this study was to determine the behavior of the visitors and to determine possible behavior that would contribute to the transmission of pathogenic microorganisms, in order to provide suggestions for visitors in the post-pandemic period.
