The strength and rigidity of base course can significantly affect the performance of pavements. The rigidity of roadways relies on the infill material used in base layers which is interdependent on its thickness and quality. With the increase in the base thickness, the performance of the base course improves but the cost associated with it also increases. Since the natural aggregates are not adequately available, use of waste materials in road construction can prove economical and environmental friendly. In this study, efficacy of geosynthetic (geocells and non-woven geotextile) reinforced quarry waste as an alternative base course materials (BCM) were investigated under static loading conditions (plate load test-PLT). By increasing the geocell height from 100 to 150 mm, the bearing capacity (BC) increased from 450 to 840 kPa. Similarly due to combined use of geocell and geotextile, BC increased from 500 to 890 kPa. The experimental results depict that the geosynthetic reinforcement increases the load bearing capacity of QWB's by 85%. Moreover, the artificial neural network analysis (ANN) was performed to predict the deformation on top of footing while considering different influential parameters. The results obtained from the ANN analysis were in good fit.

Introduction: While cadaveric dissections remain the cornerstone of education in skull base surgery, they are associated with high costs, difficulty acquiring specimens, and a lack of pathology in anatomical samples. This study evaluated the impact of a hand-crafted three-dimensional (3D)-printed head model and virtual reality (VR) in enhancing skull base surgery training.
Research Question: How effective are 3D-printed models and VR in enhancing training in skull base surgery?
Materials And Methods: A two-day skull base training course was conducted with 12 neurosurgical trainees and 11 faculty members.

Ionizing radiation induces various types of DNA damage, and the reparability and lethal effects of DNA damage differ depending on its spatial density. Elucidating the structure of radiation-induced clustered DNA damage and its repair processes will enhance our understanding of the lethal impact of ionizing radiation and advance progress toward precise therapeutics. Previously, we developed a method to directly visualize DNA damage using atomic force microscopy (AFM) and classified clustered DNA damage into simple base damage clusters (BDCs), complex BDCs and complex double-strand breaks (DSBs).

Skull base tumors such as meningiomas and schwannomas are often pathologically benign. However, surgery for these tumors poses significant challenges because of their proximity to critical structures such as the brainstem, cerebral arteries, veins, and cranial nerves. These structures are compressed or encased by the tumor as they grow, increasing the risk of unintended injury to these structures, which can potentially lead to severe neurological deficits.

Adaptive radiotherapy (ART) provides greater benefits than intensity-modulated radiotherapy (IMRT) regarding dosimetric outcomes in patients with cervical cancer. To investigate the clinical benefits of ART, we have collected data from 115 cervical cancer patients who underwent radical radiotherapy at our institution. Fifty-nine patients received a single course of IMRT.

Indigenous Australians are disproportionately affected by diabetes, with a diagnosis rate nearly four times higher than people from a non-Indigenous background. This health disparity highlights the urgent need for healthcare providers to develop cultural empathy - a critical competency for delivering culturally safe and person-centered care. Cultural empathy is essential for building trust and effective communication in diabetes education and management within Indigenous people.
