Night-time leaf conductance (g(night)) and transpiration may have several adaptive benefits related to plant water, nutrient and carbon relations. Little is known, however, about genetic variation in g(night) and whether this variation correlates with other gas exchange traits related to water use and/or native habitat climate. We investigated g(night) in 12 natural accessions and three near is...

PURPOSE Little is known about the stability of serial measures of spike counts in children or whether spike counts are an inherently stable or unstable measure. We investigated the variation in first- and second-night spike counts in children undergoing 48-h ambulatory EEG recording. METHODS We analyzed 40 consecutive 48-h ambulatory EEGs performed at Boston Children's Hospital that manifeste...

In the present paper we report the detection of intra-night variability in some of the radio-quiet quasi-stellar objects (RQQSOs) and one lobe dominated radio-loud quasi-stellar object (LDQ). To study intra-night variability, we carried out photometric monitoring of seven RQQSOs and one LDQ in Johnson V-passband using 1.2 meter optical/IR telescope at Gurushikhar, Mount Abu, India. Observations...

The survey of fish larvae assemblage variation was done in 2013 seasonally at the coastal areas of Southeastern side of Chabahar Bay. Sampling was done in 3 stations at day and night periods by a Bongo-Net with 300μ of mesh size. 29 families were identified. Clupeidae, Gobiidae and Blenniidae were dominant with more than 50% relative abundance. The PCA result was shown there were two separated ...
