I will speak up if I feel energetic: Effects of supervisor humor on employee voice.

Extant literature on supervisor humor predominantly documents its beneficial effects on the organization, but its dark side receives little attention. Drawing on ego depletion theory, we proposed a conceptual model to examine the effects of two interpersonal types of supervisor humor (i.e.

Effects of AHLs inhibitors and exogenous AHLs on the stability and activity of Anammox granules at low temperatures.

This study investigated the relationship between acyl homoserine lactones (AHLs)-based quorum sensing (QS) and the properties of Anammox granular sludge at low temperatures (11-23°C). Results indicated that adding different concentrations of AHLs inhibitors reduced the content of N-hexanoyl-dl-homoserine lactone (C6-HSL) and N-octanoyl-dl-homoserinelactone (C8-HSL) in Anammox granules on different degrees at different operation temperatures, which led to the deterioration of granules stability and activity. The important role of endogenous C6-HSL and C8-HSL signals in maintaining Anammox granular sludge stability and activity in low-temperature conditions was revealed.

Dynamic behaviours of a rationally prepared flexible MOF by postsynthetic modification of ligand struts.

Through postsynthetic modification of ligand struts, controllable conversion of a Zr MOF between rigidity and flexibility is realized. The rationally prepared flexible MOF exhibits interesting dynamic behaviours, such as reversible structural deformation, vapour sorption hysteresis and unexpected adsorption of bulky guest molecules.
