Remote sensing data in the thermal infra red (TIR) part of the spectrum provides indirect estimates of water stress – defined as a function of the ratio between actual and potential evaporation rates – at the earth surface. During the first stage of evaporation (‘‘energy limited’’ evaporation), this ratio is close to one. During the second stage of evaporation (‘‘soil controlled’’ evaporation) ...

Tahini (sesame seed paste) is a low water activity product that has been involved in several salmonellosis outbreaks. The objectives of the study were to examine over year impact aw and storage temperature tahini on viability Salmonella serovars previously stressed by drying or heat exposure. samples adjusted values 0.17, 0.35 0.50 inoculated with mixed culture containing 106-107 CFU/g 4 unstre...

The effects of acute stressor exposure on proximal (growth hormone [GH]) and distal (insulin-like growth factor-I [IFG-I] and insulin-like growth factor-binding proteins [IFGBPs]) components of the somatotropic axis are poorly understood in finfish. Rainbow trout (Oncorhynchus mykiss) were exposed to a 5-min handling disturbance to mimic an acute stressor episode, and levels of plasma GH, IGF-I...

We investigate the perception of phonemic vowel quantity contrast and its relation to word stress and vowel quality in Slovak, and fill the gap of missing experimental perception data for this language. We observe that both prosodicallydriven undershoot of unstressed vowels and the functional load affect the perception of quantity contrast. Vowel quality plays some role in quantity identificati...

In this study, we determine the acoustic correlates of primary and secondary stress in Tongan. Vowels with primary stress show differences in F0, intensity, duration, F1, and voice quality, but F0 is the best predictor of primary stress. Vowels with secondary stress are mainly cued by a difference in F0. With regards to the effects of stress on the vowel space, we find that all five Tongan vowe...

The present study examined the effect of stress on vowels, specifically duration, formant frequency and acoustic vowel space in CV syllable in Daxi Hakka Chinese. F1 and F2 values were measured at three equidistant time locations. Results show that the absence of stress results in the reduction of vowel duration, which is shortened by 23% in the unstressed condition. The presence of stress affe...

Sugarcane stalks that were drought stressed and not stressed were sampled 50 days after applying Fusilade Super (fluazifop-butyl). The stalks were sectioned and analysed for structural (fibre) and soluble (brix) carbohydrates. Levels of sucrose, glucose and fructose were determined by HPLC. The data show that total stalk dry matter was not reduced by fluazifop-butyl, regardless of whether the c...

This study presents ultrasound data from six female speakers of the Central Australian language Arrernte. We focus on the which may be considered phonemically marginal. We compare these sounds in stressed and unstressed position. Consistent with previous results on this apical contrast, we show that there are minimal differences between the retroflex and the alveolar at stop offset; however, at...

The relationship between tone pattern and word stress is investigated on different aspects. The distribution of the original tones of the unstressed syllables in disyllabic words, the perception of word stress in utterances and the allocation of sentence stresses within words are analyzed. The results of the analyses coincide quite well, indicating that tone has something to do with the engende...
