Muka Qiang has two phonological tones. Contrary to typological expectations of a two-tone system, both are types of high tone: non-high syllables are toneless. The first type of tone is a high word tone that aligns with the left edge of the word and spreads rightward, linking to as many as four syllables; lexical prosodic domains longer than four syllables have not been observed. The other tone...

a highly selective electrode for bromide ion based on aza pyrilium derivative as an excellentionophore is described.the sensor exhibits a good linear response with a slope of ( 60±1 ) mv per decadeover the concentration range of ( 1×10-3 – 9×10-6 m ) , and a detection limit of ( 3×10-6 m ) of bromideions .the electrode response is independent of ph in the range of(4.0 –9.5).selectivity coeffici...

tea is the second most commonly consumed beverage world wide. tea ( camellia sinensis ) is a naturally rich source of fluoride. the quantity of fluoride intake is important in optimizing its dental caries-preventive role. intense concentration of fluoride in tea, can lead to excessive fluoride intake which may cause health problems in turn. the measurement of fluoride intake usually requires in...

introduction: cognitive tasks are considered to be applicable and appropriate in assessing cognitive domains. the purpose of our study is to determine the relationship existence between variables of age, sex and education with selective, sustained attention and planning abilities by means of computerized cognitive tasks among healthy adults. methods: a cross-sectional study was implemented duri...

objective: hypoglycemia with multiple etiologies is a common in diabetic patients. the current study describes the probability of interaction between maprotiline, selective serotonine reuptake inhibitors like citalopram for induction of hypoglycemia. case presentation: a 47 year-old diabetic woman used tablet citalopram 20mg daily because of generalized anxiety disorder from two years ago, but ...

In this paper, we propose a new region extraction method using chroma key with a two-tone checker pattern background. The method solves the problem in conventional chroma key techniques that foreground objects become transparent if they have the same color with the background. The method utilizes the adjacency condition between two-tone regions of the background and the geometrical information ...

Two-tones (”Mooney”-esque transformations of grayscale photographs) can be difficult to recognize. However, after viewing the photographs from which two-tones were created, adults experience rapid “perceptual reorganization,” and the two-tones become immediately recognizable. In contrast to the effortless post-cue recognition seen in adults, preschoolaged children are generally unable to recogn...
