Singular value decomposition based satellite attitude determination using different sensor configurations

International Journal of Metrology and Quality Engineering, 2017
Satellite's attitude can be determined by using several different ways. In order to use a recursive filter to determine the attitude especially after crucial intervals for the satellite including detumbling, eclipse, etc., single-frame methods can be ...

Additive‐Driven Phase Control for Stable and Efficient CsPbI₃ Solar Cells Via Ambient Low‐Temperature Processing

Advanced Functional Materials, EarlyView.
CsPbI₃ perovskite solar cells face stability issues due to high annealing temperatures and moisture. Butylammonium acetate (BAAc) enables stable phase formation at 160°C in ambient laboratory conditions, enhancing efficiency and stability, achieving 18.6% PCE, and maintaining over 81% efficiency after 1,000 hours of maximum power point tracking under 1

High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

Advanced Functional Materials, EarlyView.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...

The Eclipse of Reason - A Present Time Risk

Academicus International Scientific Journal
This paper contends that technical progress, from automation in industry to artificial intelligence, might involve the risk of a humanly impoverished society. Instrumental values could overcome final values and determine the end of meaning.

Removal of Steroid Hormone Micropollutants by an Electrochemical Carbon Nanotube Membrane Flow‐Through Reactor: Role of Concentration and Degradation Mechanisms

Advanced Functional Materials, EarlyView.
A flow‐through electrochemical membrane reactor equipped with a carbon nanotube membrane eliminates the mass transfer limitation, achieving removals >97.5% for steroid hormone (SH) micropollutants through electrochemical adsorption and degradation, over a broad initial concentration varying from 50 to 106 ng L−1.

Le croissant de lune chez les Éduens et les Lingons sous le Haut-Empire

Revue Archéologique de l’Est, 2014
The crescent of the moon is very present on the funerary steles of the Lingones and Aedui. Its two horns point upwards in a position that is uncommon and which, curiously, has never intrigued archaeologists. The position is referred to as a “cradle moon”

CRISPR/Cas9‐Assisted Microrobots for Fast and Ultrasensitive “On‐The‐Fly” Next‐Generation DNA Detection

Advanced Functional Materials, EarlyView.
This work presents self‐propelled CRISPR/Cas9‐functionalized Au–MRs for rapid, amplification‐free, “on‐the‐fly” DNA detection. By harnessing motion‐assisted signal recovery, the platform achieved the limit of detection in low fM DNA concentrations, enabling detection across a wide dynamic range within only 5 min, which is significantly faster than any ...

Aristarco revisitado

Revista Brasileira de Ensino de Física
Usando as triangulações propostas pelo antigo astrônomo Aristarco, obtivemos neste trabalho o tempo total e a duração do máximo dos eclipses solares e calculamos o tempo total dos eclipses lunares. Para isso, usamos os valores do período orbital da Lua e
