saving in irrigation water is important in the early season of sugar beet. the effect of early season deficit irrigation on the sugar beet growth indexes was investigated in kabotarabad agricultural research station (esfahan) in 1998. the soil texture was silty clay and the experiment design was randomized complete block with 4 relications. six irrigation regimes were applied after. 1) 100 mm (...

If speakers repeat a phrase, their speech tends to be highly rhythmical. In a similar task without repetition, no such rhythmicity was found. This study investigates whether stress predictability, varied between tasks, affects speech rhythm. Results show that a regular speech rhythm emerges in repeated phrases (with highly predictable stress pattern), but not in other tasks without repetition (...

post traumatic stress disorder (ptsd) is a disorder of emotional and mental stress occurring as an outcome of injury or severe emotional shock. yoga may be useful in decrease of ptsd symptomology. new studies demonstrate that people suffering from ptsd can find actual relief with yoga. yoga decreases stress-induced allosteric load in three reactive systems of stress: the autonomic nervous syste...

In this paper we describe a method that detects and remedies lexical stress errors in unit selection synthesis automatically using machine learning algorithms. If unintended stress patterns can be detected following unit selection, based on features available in the unit database, it may be possible to modify the units during waveform synthesis to correct errors and produce an acceptable stress...

the most important risk factors for anxiety disorders include genes, early life stress, and current stress. these factors do not act independently but interact with each other throughout human development through examples such as epigenetic modifications and complex forms of learning. the neural substrate of pathological anxiety includes hyperactivity in the amygdala and other limbic brain regi...

We studied the guaiacol peroxidase activity, isoenzyme pattern and metal content in the needles of 2-year-old spruce grown on soils supplemented with cadmium concentrations from 1 to 21 mg kg(-1). Following exposure to cadmium, an initial increase and subsequent decrease in the activity of the soluble fraction was observed. A parallel change of their isoenzyme pattern occurred. An increase of t...

BACKGROUND The incidence of syncope exhibits a daily pattern with more occurrences in the morning, possibly as a result of influences from the endogenous circadian system and/or the daily pattern of behavioral/emotional stimuli. This study tested the hypothesis that the circadian system modulates cardiovascular responses to postural stress, leading to increased susceptibility to syncope at spec...
