Migraine among King Khaled University students; prevalence, determinants, and impact on academic life.

Background: Migraine is a common primary headache disorder that significantly affects academic life and is often associated with stress, depression, anxiety, and irregular sleep patterns among university students. This study aimed to assess the prevalence of migraine among King Khalid University (KKU) students, identify its determinants, and evaluate the impact of migraine and other headaches on academic life and performance.

Methods: An analytical cross-sectional study was conducted among 732 students from Colleges of Medicine, Pharmacy, Engineering, and Computer science.

Hyperspectral imaging reveals that sapropelic mud therapy may improve local tissue oxygenation in elderly.

Sapropelic muds have been used for centuries to treat various illnesses, but their effects and mechanisms are still under research. In this study the effects of Techirghiol sapropelic mud on tissue oxygenation in elderly patients diagnosed with neuromuscular disorders were investigated using spatial and spectral information provided by hyperspectral imaging technique. A group of 38 elderly patients with neuromuscular disorders for which they received mud therapy was studied.

Circular Economy of Construction and Demolition Waste for Nanocomposite Cement: XRD, NMR, Vickers, Voltammetric and EIS Characterization.

In this paper, we present the structural, mechanical and electrical properties of composite cement materials that can be widely used as substituent for cement. We start with the characterization of a composite cement sample using an analysis of X-ray diffraction (XRD) and nuclear magnetic resonance (NMR) spectra. The measurements of the Vickers hardness, cyclic and sweep linear voltammetry and electrochemical impedance spectroscopy (EIS) of composite cement materials were also recorded.

Nanocomposites Derived from Construction and Demolition Waste for Cement: X-ray Diffraction, Spectroscopic and Mechanical Investigations.

In the production of cement, raw materials can be partially substituted by regenerable waste provided from glasses, construction and demolition waste in order to reduce the environmental problem and burden of landfills. In this study, limestone-silicate composites were synthesized using starting materials such as glass waste and lime, brick, autoclaved aerated concrete (ACC), mortar or plaster waste. The structure and mechanical properties of the nano-composite materials have been studied.

Hyperspectral imaging with machine learning for in vivo skin carcinoma margin assessment: a preliminary study.

Surgical excision is the most effective treatment of skin carcinomas (basal cell carcinoma or squamous cell carcinoma). Preoperative assessment of tumoral margins plays a decisive role for a successful result. The aim of this work was to evaluate the possibility that hyperspectral imaging could become a valuable tool in solving this problem.
