Evaluating Self-Produced PLA Filament for Sustainable 3D Printing: Mechanical Properties and Energy Consumption Compared to Commercial Alternatives by Luca Fontana, Paolo Minetola, Mankirat Singh Khandpur, Alberto Giubilini

“…Specimens were printed at two layer heights (0.2 mm and 0.3 mm) and four infill densities (25%, 50%, 75%, and 100%). The self-produced filament exhibited lower diameter precision (1.67 ± 0.21 mm), which resulted in mass variability up to three orders of magnitude higher than that of the commercial filament. …”

The Robust Detection and Spatial Distribution of Acetaldehyde in Orion KL: Atacama Large Millimeter/submillimeter Array Observations and Chemical Modeling by Miwha Jin, Anthony J. Remijan, Robin T. Garrod, Giseon Baek, Martin Cordiner, Steven Charnley, Eric Herbst, Jeong-Eun Lee

“…The relative abundance ratios obtained from the model are highly sensitive to the assumed kinetic temperature, which accounts for the high spatial variability of the aldehyde ratios observed toward Orion KL.…”

Retrieval of Dissolved Oxygen Concentrations in Fishponds in the Guangdong–Hong Kong–Macao Greater Bay Area Using Satellite Imagery and Machine Learning by Keming Mao, Dakang Wang, Shirong Cai, Tao Zhou, Wenxin Zhang, Qianqian Yang, Zikang Li, Xiankun Yang, Lorenzo Picco

“…This study also employed satellite imagery from multiple periods to analyze the spatiotemporal distribution and trends of DO concentrations over the past decade, aiming to enhance understanding of DO variability. The results indicate that the average DO concentration in fishponds across the GBA was 7.44 mg/L with a statistically insignificant upward trend. …”

Impact of latitudinal position and ice cover on wave and temperature dynamics in the Laptev Sea and the Sea of Okhotsk by Kovalev, Dmitry P., Kovalev, Peter D, Borisov, Aleksander S., Zarochintsev, Vitaly S., Kirillov, Konstantin V.

“…In the Sea of Okhotsk, spectral peaks at periods of 22.7 and 29.2 min were observed, associated with the edge wave activity, while pronounced spectral variability in February was linked to the formation of cracks and polynyas. …”
