to determine rice yield loss resulting from blast disease (magnaporthe grisea) at the corp's different growth stages, a field experiment was conducted at the rice research institute of iran, rasht. rice local cultivar hashemi was transplanted to 3×4m plots for the experimental treatments (time of disease evaluation) each treatment was replicated 4 times. under natural infection conditions,...

introdouction: age estimation is an important issue in forensics, particularly for treatment planning and determining patients’ rights. radiographic evaluation of the third molar developmental stage is a significant criterion for age estimation. the pattern of tooth development is largely heritable and varies from race to race. the objective of this study was to radiographically examine and com...

for estimating plants water requirement at the different stages of plant growth, determination of crop coefficient is very important. therefore, this study was conducted to determine the crop coefficient of borage in research lands of faculty of agriculture at the university of tabriz in 2013. for this purpose, drainage lysimeter with diameter of 1.5 meter and depth of 1.7 meter was used for de...

Human deep sleep is characterized by reduced sensory activity, responsiveness to stimuli, and conscious awareness. Given its ubiquity and reversible nature, it represents an attractive paradigm to study the neural changes which accompany the loss of consciousness in humans. In particular, the deepest stages of sleep can serve as an empirical test for the predictions of theoretical models relati...

The purpose of this study was to examine the effects of a truss mattress upon sleep and bed climate. The truss mattress which has been designed to decrease the pressure and bed climate humidity was tested. Six healthy female volunteers with a mean age of 23.3 years, served as subjects. The experiment was carried out under two conditions: a truss mattress (T) and a futon (F) (Japanese bedding). ...

STUDY OBJECTIVES The program provides a unique opportunity to compare a large number of scorers with varied levels of experience to determine sleep stage scoring agreement. The objective is to examine areas of disagreement to inform future revisions of the AASM Manual for the Scoring of Sleep and Associated Events. METHODS The sample included 9 record fragments, 1,800 epochs and more than 3,2...

The goal of this study is to contribute to discussions about age-related changes in electroencephalogram (EEG) complexity. Eight characteristics of complexity were evaluated for sleep EEG of 175 healthy subjects. The complexity of the sleep EEG significantly increased up to the age of about 60 years. Over 60 years, the complexity stagnated or slightly decreased. The same tendencies were manifes...

this study was conducted to examine morphometric and meristic characteristics alongside pigmentation patterns of bream larvae, abramis brama orientalis, in four stages of larval development. morphological characters including total length (tl), standard length (sl), notochord length (nl), head length (hl), head depth (hd), eye diameter (ed) and mouth width (mw) were examined from hatching time ...
