Abstract Water temperature is an important abiotic driver of aquatic ecosystems. It influences many aspects of an organism's existence including its metabolic, growth and feeding rates; fecundity; emergence; behaviour and ultimately survival. This study determined the upper thermal limits of a range of aquatic macroinvertebrates from rivers in the ...

Abstract In this study, the maximum and minimum lethal temperatures (LT50) of L. intermedia and L. laeta were determined in two treatments: gradual heating (25–50°C) and cooling (25°C to −5°C), and 1 h at a constant temperature. In gradual temperatures change, L. intermedia mortality started at 40°C and the LT50 was 42°C; for L.

Salt formation of benzphetamine and etryptamine as a potential means of obtaining sustained release and/or prolonged action was studied by measuring the median lethal time (LT50) in mice and its relationship to in vitro dissolution rates and solubilities. Both the LT50 and LD50 increase as the in vitro dissolution rate, determined at pH 7.2, decreases.

Grapevine winter hardiness is governed by several factors besides extreme weather conditions, such as site-specific soil factors (texture, composition, moisture, drainage), vine water status, and yield.

Testing the differences of LT50, LD50, or ED50
Canadian Journal of Forest Research, 2018An approximate method is derived for testing the differences of LT50, LD50, or ED50, which indicate the temperature or dose needed to kill or damage half of the plants, respectively.

Ultrapure Blue Phosphorescent Organic Light-Emitting Diodes Employing a Twisted Pt(II) Complex.
ACS Applied Materials and Interfaces, 2021Described herein is a stable complex, Pt(mpzpyOczpy-mesi), embodying efficient, narrow blue emission. The highly twisted structure of the complex improves the stability and efficiency of photo- and electroluminescence by reducing the intermolecular ...
