A Quantitative Model for Magnetic Shielding of Lunar Polar Ice: BowShock Formation, Streamline Deflection, and Testable Predictions

open access: yes
How to Read This Paper This paper is structured so that a reader can enter at different levels depending on what they care about—magnetic fields, plasma flow, ice accumulation, or testable predictions. The physics builds layer by layer, but you don’t need to read every section to follow the main idea.

Investigation of the flexural properties of reinforced concrete beams strengthened by externally bonded steel plates. [PDF]

open access: yes, 1980
It is sometimes necessary to strengthen in situ concrete structures. Externally bonded plate reinforcement has been successfully applied to structures with subsequent satisfactory performance.

Biocompatible (Nano)Composites Based on Poly(ε‐Caprolactone)/Siloxene

open access: yesPolymer Engineering &Science, EarlyView.
Bio‐inert and biocompatible pCLO/siloxene (nano)composites with enhanced mechanical properties. ABSTRACT The work focuses on the synthesis of the siloxene nanofiller and its subsequent use in the preparation of poly(ε‐caprolactone)/siloxene (nano)composites via in situ polymerization and melt blending.

Theoretical estimation of floating ice sheet deflection caused by the motion of a submerged object

open access: yes, 2019
The vertical deflection of floating ice sheets subjected to the movements of an underwater object is the subject of the present theoretical study. Steady deflections are estimated based on theories of small deformation of thin plates and potential flow using Fourier and Laplace transform techniques and complex analysis.

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

open access: yesPolymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

Commercial permethrin elicits chemoreceptive responses on different Anopheles gambiae sensory appendages

open access: yesPest Management Science, EarlyView.
Anopheles gambiae mosquitoes exhibit takeoff responses when presented to commercial permethrin headspace. This product elicits electrophysiological activity in the antennae and tarsi. However, only the chemical information acquired from the tarsi plays a major role in the observed behavioral response.

Wind Tunnel Measured Effects on a Twin-Engine Short-Haul Transport Caused by Simulated Ice Accretions

open access: yes, 1996
A series of wind tunnel tests were conducted to assess the effects of leading edge ice contamination upon the performance of a short-haul transport. The wind tunnel test was conducted in the NASA Langley 14 by 22 foot facility. The test article was a 1/8

Analysis of the fractional scattering contribution in the forward peak for multicomponent systems

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Derivation and justification of mixing rules for multicomponent systems. A novel formulation of the delta‐Eddington scaling rule. Analytical guidance for comparing radiative transfer results. Abstract The widely used δ‐Eddington approximation improves the accuracy of radiative transfer calculations by representing the fraction of scattering into the ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Geomorphic Effects and Habitat Impacts of Large Wood at Restoration Sites in New England

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Large wood (used interchangeably with the term “instream wood”), which refers to trees, logs and other wood within a channel, is beneficial to river ecosystems and is being used more frequently as a component of river restoration projects. We identified metrics to evaluate the effectiveness of large wood to promote ecological and geomorphic ...
