Intrarenal hemangiomas lack concise clinicopathologic information, due to the predominance of single case reports and inclusion of other vascular neoplasms and hemangiomas of perirenal, hilar, and renal vein origin. Herein, in this multi-institutional study we evaluate clinicopathologic features of 39 intrarenal hemangiomas. The median age was 62 years (range = 27-94 years; 2:1 male to female ratio), with left-sided predominance (left = 21, right = 13; one case was bilateral).

- Wind power is an eco-friendly and growing renewable energy source, and this study assesses its potential in the Al-Jouf region of Saudi Arabia using 21 years of historical wind speed data.
- The Weibull distribution was applied to model wind characteristics, revealing an average wind speed of 4.38 m/s and highlighting the Vestas V126 turbine as the most effective option, potentially serving 46,000 people if 100 units are installed.
- The findings suggest Al-Jouf is a promising site for large-scale wind projects, offering practical insights for stakeholders in the wind energy sector.
The present study outlines the preparation of a ternary nanocomposite film comprising of polyaniline doped with camphor sulfonic acid (PANI), reduced graphene oxide (rGO), and graphitic carbon nitride (g-CN), and delves into its thermoelectric performance. PANI is known to possess high electrical conductivity () and poor thermal conductivity (). However, its potential for thermoelectric applications is constrained by the low value of the Seebeck coefficient ().

Here, we present the fabrication of a double-layer nanocomposite structure for the electronegative layer in a TENG, which resulted in the enhanced generation of surface charges and retention of generated charges. The double-layer structure is a stack of two different nanocomposite layers, in which the top layer is a nanocomposite of PVDF and MXene and the bottom layer is a nanocomposite layer of PDMS and NaNbO nanoparticles.

- Early research shows that the body can adapt to space travel changes, but prolonged spaceflight over 6 months poses complex health risks, particularly to the cardiovascular (CV) system.
- Long-term exposure to microgravity causes fluid shifts and alters blood pressure regulation, which can lead to cardiovascular problems like reduced venous pressure and increased cardiac output.
- Additionally, astronauts may experience cardiac muscle atrophy, changes in hematocrit, and arrhythmias, along with increased risks of coronary artery issues from radiation exposure during deep space missions.
