Autophagy, 2012 Autophagy plays an important role in the cellular response to a variety of metabolic stress conditions thus contributing to the maintenance of intracellular homeostasis. Studies in yeast have defined the genetic components involved in the initiation of autophagy as well as the progression through the autophagic cascade.

Ammonia toxicity: from head to toe? [PDF]
, 2016 Ammonia is diffused and transported across all plasma membranes. This entails that hyperammonemia leads to an increase in ammonia in all organs and tissues.

Estuarine Nitrifiers: New Players, Patterns and Processes [PDF]
, 2010 Ever since the first descriptions of ammonia-oxidizing Bacteria by Winogradsky in the late 1800s, the metabolic capability of aerobic ammonia oxidation has been restricted to a phylogenetically narrow group of bacteria.

Ammonia removal in anaerobic digestion by biogas stripping: an evaluation of process alternatives using a first order rate model based on experimental findings [PDF]
, 2011 The feasibility of biogas stripping to remove ammonia in the anaerobic digestion of source segregated food waste was investigated. It was found in batch experiments that ammonia could be removed from digestate and that the removal followed 1st order ...

Animals, 2020 This study was carried out to evaluate the effect of the addition of the non-starch polysaccharide enzymes cocktail (NSPEC) on growth performance, nutrient digestibility and gas emissions in a corn-miscellaneous meal-based diet for finishing pigs.

Acta Crystallographica Section E Structure Reports Online, 2011 The asymmetric unit of the title compound, C(18)H(18)BN or (C(6)H(5))(3)B·NH(3), comprises two crystallographically independent but virtually identical mol-ecules. Mol-ecules of one type are linked with each other by N-H⋯π inter-actions, generating an infinite column aligned along the b-axis direction.

Hot Ammonia around Young O-type Stars. II. JVLA imaging of highly-excited metastable ammonia masers in W51-North [PDF]
A&A 573, A109 (2015), 2014 We have used the JVLA at the 1 cm band to map five highly-excited metastable inversion transitions of ammonia, (J,K)=(6,6), (7,7), (9,9), (10,10), and (13,13), in W51 IRS2 with ~0.2 angular resolution. We present detections of both thermal (extended) ammonia emission in the five inversion lines, with rotational states ranging in energy from about 400 ...

Recent progress towards the electrosynthesis of ammonia from sustainable resources [PDF]
, 2017 Ammonia (NH3) is a key commodity chemical of vital importance for fertilisers. It is made on an industrial scale via the Haber Bosch process, which requires significant infrastructure to be in place such that ammonia is generally made in large ...

Evaluation of flamelet-based models for liquid ammonia combustion in a temporally evolving mixing layer [PDF]
, 2023 Liquid ammonia combustion can be enhanced by co-firing with small molecular fuels such as methane, and liquid ammonia will undergo flash evaporation due to its relatively low saturation pressure. These characteristics, involving the presence of multiple fuel streams, a rapid phase change process, and strong heat loss, pose challenges for flamelet ...
