The aim of this research is to investigate the effects of different irrigation and fertilization levels on the yield and quality of bioethanol and bioplastic obtained from sugar beet molasses. A two-year trial (2019-2020) was conducted at Bursa Uludag University Yenişehir İbrahim Orhan Vocational School Application Area. Physical analyzes of sugar beet roots and bioplastic prod…
Background: Radiation therapy (RT) is an essential and effective part of the management of adult brain tumors. Proton therapy (PT) has emerged as an alternative radiation treatment modality. Although the number of patients receiving PT for a brain tumor is increasing, the potential clinical superiority of PT over photon RT in patients with brain tumors remains a matter of debat…

Additive manufacturing (AM) enables the fabrication of complex metallic components through layer-by-layer processing directly from digital models. Among AM techniques, material extrusion–based processes such as fused filament fabrication (FFF) provide an accessible method for producing metal parts using filament feedstocks composed of metal powders and polymer binders. When app…

In an era marked by increasing demand for advanced anticounterfeiting measures, we introduce a four-dimensional (4D) dynamic physical unclonable function that uses defect-engineered photoluminescence blinking in all-inorganic CsPbBr 3 perovskite quantum dots (QDs) embedded within a polymethylmethacrylate matrix. Even within a single z -axis layer, this system achieves an unprec…

The COVID-19 pandemic caused global scarcity of medical-hospital supplies, aggravated by import dependency and disruption of logistic chains. In this context, additive manufacturing became an emergency solution to meet critical demands, such as the production of blades for videolaryngoscopy (VL). The Federal Institute of Rio Grande do Sul (IFSul) developed actions to support th…

OBJECTIVE: This study proposes a 2π solid angle-based heuristic framework for non-coplanar volumetric modulated arc therapy (VMAT) in patients with multiple brain metastases (MBM) to automate treatment angle selection. Approach: Fifty-two patients with MBM (2-8 targets) were retrospectively included. A hybrid heuristic framework was constructed: first, a volume-weighted cumulat…

BACKGROUND: Stereotactic radiosurgery requires high precision and stable target immobilization, especially for extracranial lesions prone to motion. Lesions located low in the neck pose unique challenges because of limited access and potential movement from mandibular activity. This case illustrates a novel hybrid fixation technique that combines a stereotactic G-frame with a t…
