abstract three pear genotypes (nazkeh, lasoreh and qevilah), grown in 2l containers, were studied under four irrigation regimes in order to evaluate the leaf relative water content (rwc), photosynthesis, leaf gas exchanges and plant dry weight induced by water stress. control treatment everyday was irrigation. irrigation was practiced when soil water potential reached at -0.4, -0.8, and -1.2 mp...

objective(s) herbal waters are extensively used in most parts of iran including mashhad. visiting a patient with total blindness due to daily ingestion of around 200 ml of herbal water (plant forty water) per day for six months was the rational for methanol determination in all herbal waters available in mashhad markets. materials and methods a total of two hundred and nineteen bottles of herba...

Vibrational modes and their interactions affect numerous physical processes in condensed-matter systems. In the present work, hydrogen vibrations in Se-doped AlSb were investigated with first-principles calculations. Vibrational frequencies were calculated for the longitudinal, transverse, wag (bending), and stretch modes of the Al-H complex. The Al-H stretch mode interacts with a combination m...

Terahertz laser VRT spectra of the water dimer consisting of 731 transitions measured with an average precision of 2 MHz and involving four ~D2O!2 intermolecular vibrations ~one previously published! have been measured between 65 and 104 cm. The precisely determined energy level patterns differ both qualitatively and quantitatively from the predictions of several dimer potentials tested, and re...

Carbon dioxide storage combined with enhanced oil recovery (CCS-EOR) is an important approach for reducing greenhouse gas emissions. We use pore-scale imaging to help understand CO2 and during CCS-EOR at immiscible near-miscible injection conditions. study in situ flooding oil-wet reservoir rock elevated temperature pressure using X-ray micro-tomography. observe the predicted, but hitherto unre...

Abstract Three-phase flow in porous media is encountered many applications including subsurface carbon dioxide storage, enhanced oil recovery, groundwater remediation and the design of microfluidic devices. However, pore-scale physics that controls three-phase under capillary dominated conditions still not fully understood. Recent advances three-dimensional imaging have provided new insights in...

METHODS OF ELECTROFISHING have been developed successfully for use in fresh-water ponds and streams, but this equipment is not effective in sea water because the high conductivity of salt water greatly changes the power requirements (Smolian, 1944). If this obstacle can be overcome, it is reasonable to assume that electrofishing can be conducted in the sea with a success which would be at least...

This paper describes the input specification language of the WAG Sentence Generation system. The input is described in terms of Halliday’s (1978) three meaning components, ideational meaning (the propositional content to be expressed), interactional meaning (what the speaker intends the listener to do in making the utterance), and textual meaning (how the content is structured as a message, in ...
