Aerodynamic characteristics of an ogive-nose spinning projectile
Sādhanā, 2018 This work experimentally investigates the Robins–Magnus effect on a 5-caliber spinning projectile at a low subsonic Mach number of 0.1 corresponding to a Reynolds number of 3.2 × 105 based on the model length. The model configuration tested was a cylinder with spherically blunt tangent ogive nose portion.

Sensitivity of Spin Parameters to Uncertainties of the Aircraft Aerodynamic Model [PDF]
Journal of Aircraft, 2020 Reliable prediction of aircraft post-stalled dynamics is entirely dependent on the adequacy of the aerodynamic model. A mathematical model of aerodynamic characteristics of a light aircraft is developed for a wide range of angles of attack, sideslip, and angular rates.

Influence of a humidor on the aerodynamics of baseballs
, 2008 We investigate whether storing baseballs in a controlled humidity environment significantly affects their aerodynamic properties. To do this, we measure the change in diameter and mass of baseballs as a function of relative humidity (RH) in which the ...

Circulating histones as clinical biomarkers in critically ill conditions
FEBS Letters, EarlyView.Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.

Paradoxical popups: Why are they hard to catch?
, 2008 Even professional baseball players occasionally find it difficult to gracefully approach seemingly routine pop-ups. This paper describes a set of towering pop-ups with trajectories that exhibit cusps and loops near the apex.

Molecular Oncology, EarlyView.Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...

The Kinematics of Falling Pterocymbium Tinctorium Seeds
International Scholastic Journal of Science, 2020 Pterocymbium tinctorium (Thai:ปออีเก้ง, Por-Ae-Keang ) is a tree found in Thailand and other Southeast Asian countries. The fruit, containing a single seed with an attached single wing extending to one side and a hollow boat-shaped structure that braces

Molecular Oncology, EarlyView.Cancer‐associated fibroblasts (CAFs) promote cancer growth, invasion (metastasis), and drug resistance. Here, we identified functional and diverse circulating CAFs (cCAFs) in patients with metastatic prostate cancer (mPCa). cCAFs were found in higher numbers and were functional and diverse in mPCa patients versus healthy individuals, suggesting their ...
