UV “Indices”—What Do They Indicate?
Ultra-Violet (UV) radiation covers the spectrum of wavelengths from 100 to 400 nm. The potency and biological activity for a variety of endpoints differ by wavelength. For monitoring and communication purposes, different UV action spectra have been developed. These spectra use different weighting functions. The action spectrum for erythemal dose is the most widely used one. This erythemal dose ...
متن کاملUniversal Grammar and Chaos/Complexity Theory: Where Do They Meet And Where Do They Cross?
Abstract The present study begins by sketching "Chaos/Complexity Theory" (C/CT) and its applica-tion to the nature of language and language acquisition. Then, the theory of "Universal Grammar" (UG) is explicated with an eye to C/CT. Firstly, it is revealed that CCT may or may not be allied with a theory of language acquisition that takes UG as the initial state of language acquisition for ...
متن کاملIntraepithelial lymphocytes in the villous tip: do they indicate potential coeliac disease?
BACKGROUND The counting of intraepithelial lymphocytes (IELs) in the villous tips of architecturally normal small bowel biopsy specimens was proposed as a method to measure mucosal infiltration in gluten sensitive patients. AIMS To apply this straightforward method in duodenal biopsy specimens from patients affected by potential coeliac disease (PCD) to verify whether it can discriminate thes...
متن کاملDo speakers realize the prosodic structure they say they do?
In this paper we describe a study in which a comparison was made between prosodic structures as realized in a spoken version of a text and as assigned by annotators of this text on paper. The prosodic structures were assigned by experts. This study puts to test the strategy of annotating text on paper to obtain a HUMAN reference of the prosodic structure that would be assigned when reading text...
متن کاملOsteoclasts: what do they do and how do they do it?
As Americans live longer, degenerative skeletal diseases, such as osteoporosis, become increasingly prevalent. Regardless of cause, osteoporosis reflects a relative enhancement of osteoclast activity. Thus, this unique bone resorptive cell is a prominent therapeutic target. A number of key observations provide insights into the mechanisms by which precursors commit to the osteoclast phenotype a...
