Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.Reprogrammable multi‐material smart textiles knitted from liquid crystal elastomer fibers undergo 2D and 3D deformation under thermal and photo stimuli. Circularly knitted tubular structures reversibly contract in radial and axial directions, enabling autonomous climbing, liquid release, and micro pumping.

A study on various methods of supplying propellant to an orbit insertion rocket engine [PDF]
Various types of pumps and pump drives were evaluated to determine the lightest weight system for supplying propellants to a planetary orbit insertion rocket engine. From these analyses four candidate propellant feed systems were identified. Systems Nos.

In‐Field Validity and Inter‐Unit Variability of Metabolic Carts During Simulated Exercise
Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 5, May 2026.ABSTRACT The present study had three main objectives: (a) to evaluate the in‐field validity of different commercially available cardiopulmonary exercise testing (CPET) systems when used by end‐users following typical calibration procedures, (b) to measure the variability in accuracy among identical CPET units, and (c) to explore the relationship ...

Experimental studies on thermodynamic effects of developed cavitation [PDF]
A method for predicting thermodynamic effects of cavitation (changes in cavity pressure relative to stream vapor pressure) is presented. The prediction method accounts for changes in liquid, liquid temperature, flow velocity, and body scale.

The High Speed Water Tunnel three-component balance [PDF]
, 1955 An experimental program was initiated in the High Speed Water Tunnel to measure force coefficients for hydrofoils under cavitating conditions. This program necessitated either a new force balance or a major modification of the existing one.
