Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Presentation of preload and afterload to isolated heart preparations
Abstract figure legend The heart can be isolated, and when this is so, it must be subjected to loading conditions. Over the past few decades, various loading methods have been developed to prescribe preload and afterload to isolated working‐heart preparations.

Insight of Elementary Steps on the Polyethylene and Polypropylene Co‐Pyrolysis
Pyrolysis of PP initiates first, accelerating PE cracking via secondary radical transfer, leading to n‐hydrocarbon yield enhancement. Py–GC/MS and nanoreactor computation are in agreement on the elementary step proposal. ABSTRACT Pyrolysis with gas chromatography & mass spectrometry (Py–GC/MS) technique was employed to analyze the yield variation of ...

ABSTRACT Introduction/Materials Modern agriculture faces the challenge of balancing high crop yields with sustainable resource management and nutritional quality. Here, soil and soilless systems (hydroponics and aquaponics) for cultivating the day‐neutral cultivar ‘Albion’ of the garden strawberry (Fragaria × ananassa Duch.) were compared in terms of ...

ABSTRACT Ocean wave energy has enormous potential for sustainable power generation but conventional technologies often face challenges in efficiency, durability, and adaptability to specific sites. Triboelectric nanogenerators (TENGs) are able to convert irregular and low frequency water motion into electrical energy, but their performance depends on ...
