Variants of the Budkyo hydrological model describe the effects of land use change on annual water yield. A recent modification using a simple process-based ecohydrological model provides insight into the partitioning of rainfall between runoff and evapotranspiration. In particular, the ‘effective vegetation rooting depth’ becomes the single free parameter in the model and can be related to land...

The aim of this quasi-experimental study was to examine the effects of maternal pethidine during labour on the developing breast feeding behaviour in infants in the first 2 h after birth compared with infants not exposed to pethidine. Forty-four healthy infants were observed immediately after birth. They were placed skin-to-skin on their mothers' chests. The development of mouth and sucking mov...

● Background and aims. The objective of this study was to test whether the mean values of several root morphological variables were related to the ability to develop root-borne shoots and/or shoot-borne roots in a wide range of vascular plants. ● Methods. A comparative study was carried out on the 123 most common plant species from eroded lands in NE Spain. After careful excavations in the fiel...

Drought is the most serious abiotic stress limiting rice production, and deep root is the key contributor to drought avoidance. However, the genetic mechanism regulating the development of deep roots is largely unknown. In this study, the transcriptomes of 74 root samples from 37 rice varieties, representing the extreme genotypes of shallow or deep rooting, were surveyed by RNA-seq. The 13,242 ...

Computer R apid change in information technology brings with it a frequent need to undo the effects of previous culture change efforts. This process, while often challenging and frustrating, offers numerous rewards for success. Organizations can change from slow, reactive, adversarial, separated software and systems engineering processes to unified, concurrent processes. These processes better ...

The article proposes the square-rooting circuit. It bases the square-law characteristics of CMOS operating in saturation region for generating square-root function. The principle of the research is attained by the currentmirror circuit, which controls the voltages. The designed circuit dominates current as input and voltage as output. The structure of the circuit is simplified by only seven CMO...

in order to micropropagate of four vigorous rootstocks of pear, including pyrus betulifolia, konjuni, dargazi and gh1, effects of basic plant culture media (ms, ql and modified ql), cytokinins and auxins on productivity, proliferation and rooting were studied in seed and plant improvement institute, karaj. the highest amount of productivity for all rootstocks was observed in ql medium. among pe...
