Cloud-Enabled Multi-Axis Soilless Clinostat for Earth-Based Simulation of Partial Gravity and Light Interaction in Seedling Tropisms

AgriEngineering
Understanding the combined gravi-phototropic behavior of plants is essential for space agriculture. Existing single-axis clinostats and gel-based grow media provide limited simulation fidelity.

Configuration of Late Archaean Chilimanzi and Razi Suites of Granites, South-Central Zimbabwe Craton, From Gravity Modelling: Geotectonic Implications [PDF]

Pure and Applied Geophysics, 2019
The subsurface geometry of five representative late Archaean ‘Chilimanzi and Razi’ suite plutons in the Zimbabwe craton (ZC) has been investigated by gravity modelling constrained in part by surface geology, density measurements and seismic information, to determine their 3D configuration and infer tectonic context of emplacement. The generally K-rich,

Formation of Igneous Layering in Granodiorite by Gravity Flow: a Field, Microstructure and Geochemical Study of the Tuolumne Intrusive Suite at Sawmill Canyon, California [PDF]

Journal of Petrology, 2008
Layered granites and granodiorites occur in many plutons. They occur, together with non-layered granodiorites, at the margin of the Tuolumne Intrusive Suite, one of the largest late Cretaceous intrusions in the Sierra Nevada. Results from field observations, quantitative microstructural analysis and whole-rock compositions from the non-layered Kuna ...

Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

FEBS Open Bio, EarlyView.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...

Versatile vector tools for efficient protein screening across multiple expression systems

FEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Gravity modelling of the Blatchford Lake Intrusive Suite, Northwest Territories

, 1994
The geometry of the Blatchford Lake Intrusive Suite, a complex of alkaline igneous rocks on the north shore of Hearne Channel, Great Slave Lake, Northwest Territories, was investigated by a detailed gravity survey (1-2 km station spacing) along two east-west traverses. Modelling of the resulting gravity profiles indicates that the granitic and syenitic

A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Exoskeleton energetics: Implications for planetary extravehicular activity [PDF]

, 2017
Humans first visited another world nearly 50 years ago and are poised to return to the Moon and visit Mars in the coming decade(s). Developing a space suit that supports safe, efficient, and effective exploration despite the extremes of temperature ...
