Influence of different UV spectra and intensities on yield and quality of cannabis inflorescences.

The raising economic importance of cannabis arouses interest in positively influencing the secondary plant constituents through external stimuli. One potential possibility to enhance the secondary metabolite profile is the use of UV light. In this study, the influence of spectral UV quality at different intensity levels on photomorphogenesis, growth, inflorescence yield, and secondary metabolite composition was investigated.

Language as social action: Gertrude Buck, the "Michigan School" of rhetoric, and pragmatist philosophy.

In the late 19th and early 20th centuries, Gertrude Buck and collaborators developed a sociologically and pragmatist-informed approach to language that has been neglected in later scholarship. Buck approached the study of language from the standpoint of pragmatist functional psychology, which is indebted to John Dewey's pragmatism at the University of Michigan, and which views language as a normal, dynamic action of human organisms engaged in necessary cooperative relations with one another. Her approach overcomes the small-minded pragmatism that would criticize figurative or poetic language as impractical, and instead shows how figuration is essential to the particular ways in which language is action that conveys meaning to others and serves broader social functions.

The construction of mind, self, and society: the social process behind G. H. Mead'S social psychology.

Mind, Self, and Society, the posthumously published volume by which George Herbert Mead is primarily known, poses acute problems of interpretation so long as scholarship does not consider the actual process of its construction. This paper utilizes extensive archival correspondence and notes in order to analyze this process in depth. The analysis demonstrates that the published form of the book is the result of a consequential interpretive process in which social actors manipulated textual documents within given practical constraints over a course of time.

A planar, chip-based, dual-beam refractometer using an integrated organic light-emitting diode (OLED) light source and organic photovoltaic (OPV) detectors.

We present a simple chip-based refractometer with a central organic light-emitting diode (OLED) light source and two opposed organic photovoltaic (OPV) detectors on an internal reflection element (IRE) substrate, creating a true dual-beam sensor platform. For first-generation platforms, we demonstrate the use of a single heterojunction OLED based on electroluminescence from an Alq(3)/TPD heterojunction (tris-(8-hydroxyquinoline)aluminum/N,N'-bis(3-methylphenyl)-N,N'-diphenylbenzidine) and light detection with planar heterojunction pentacene/C(60) OPVs. The sensor utilizes the considerable fraction of emitted light from conventional thin-film OLEDs that is coupled into guided modes in the IRE, instead of into the forward (display) direction.
