Stimulation of root acid phosphatase by phosphorus deficiency is regulated by ethylene in Medicago falcata
Phosphorus deficiency Ethylene Medicago falcata Acid phosphatase activity Phosphate transporters Organic phosphorus
2015/2/5
Plants have developed numerous strategies to cope with phosphorus (P) deficiency resulting from low availability in soils. Evolution of ethylene and up-regulation of root secreted acid phosphatase act...
Self-regulated fueling of galaxy centers: Evidence for star formation feedback
kinematics dynamics galaxies:
2014/12/23
Using new, high-resolution interferometric observations of the CO and HCN molecules, we directly compare the molecular and ionized components of the interstellar medium in the center of the nearby spi...
Follicle cell calmodulin: transcript accumulation in vitellogenic follicles of {\it Blattella germanica\/} is regulated by juvenile hormone
Calmodulin cells calmodulin oocytes vitellogenesis early embryo
2014/12/11
Calmodulin (CaM) is a major intracellular calcium receptor. There is abundant calmodulin (CaM) in the oocytes and eggs of B. germanica during vitellogenesis and early embryogenesis. The accumulation o...
Energy availability signals and the prohormone convertase 1 gene are regulated by Nhlh2
Gene regulation signals transcription factors leptin thalamus arcuate nucleus neurons
2014/12/11
Body weight is controlled by gene regulation through the activation of signal transduction pathways which ultimately regulate transcription factors and their gene targets. Fluctuating leptin levels re...
Feedback Regulated Star Formation: From Star Clusters to Galaxies
Feedback Regulated Star Formation Clusters Galaxies
2011/9/28
This paper summarises results from semi-analytical modelling of star formation in protocluster clumps of different metallicities. In this model, gravitationally bound cores form uniformly in the clump...
Accretion-regulated star formation in late-type galaxies
Accretion-regulated star late-type galaxies
2010/11/15
We develop a four-phase galaxy evolution model in order to study the effect of accretion of extra-galactic gas on the star formation rate (SFR) of a galaxy. Pure self-regulated star formation of isola...

Flood routing regulated flows Medjerda River
2009/12/4
Released flows from the Sidi Salem Dam Reservoir on the Medjerda River (Northern Tunisia) were routed downstream along the river lower water course using both hydrologic and hydraulic flood routing te...
Seasonal Fluctuations of Physical and Chemical Parameters of a Weir Basin in a Regulated West Norwegian River
Seasonal Fluctuations Physical Chemical Parameters Weir Basin
2009/10/28
Both before (1967-69) and after (1976-78) the regulation of the river Ekso in
western Norway, physical and chemical analyses were made of the river water.
After the regulation water samples for chem...
Accounting for global-mean warming and scaling uncertainties in climate change impact studies: application to a regulated lake system
climate change impact Regional Climate Models uncertainty analysis impact analysis hydrological modelling
2009/5/8
A probabilistic assessment of climate change and related impacts should consider a large range of potential future climate scenarios. State-of-the-art climate models, especially coupled atmosphere-oce...
What would have happened to the ozone layer if chlorofluorocarbons（CFCs）had not been regulated?
ozone layer chlorofluorocarbons CFCs
2009/3/31
Ozone depletion by chlorofluorocarbons (CFCs) was first proposed by Molina and Rowland in their 1974 Nature paper. Since that time, the scientific connection between ozone losses and CFCs and other oz...
Born-regulated理论中的光线偏转
Born-regulated引力理论 光线偏折 爱因斯坦相对论
2013/12/10
根据爱因斯坦的引力场理论，当光线通过引力场时受到引力的作用而发生偏转.对光线在引力场中偏转的研究有助于解决引力透镜问题，对研究宇宙中的暗能量也是有意义的.根据Born-regulated引力理论的时空度规来研究光线偏折.推导Born-regulated理论中的光线偏转角为Δφ≈4Mrmin-4Mrmin49k2βr6min.很明显，结果显示当β→0和k→0时，Δφ→4Mrmin，这正是由爱因斯坦理...
Tecnical Note: Analysis of non-regulated vehicular emissions by extractive FTIR spectrometry: tests on a hybrid car in Mexico City
non-regulated vehicular emissions extractive FTIR spectrometry hybrid car Mexico City
2009/1/20
A methodology to acquire valuable information on the chemical composition and evolution of vehicular emissions is presented. The analysis of the gases is performed by passing a constant flow of a sam...
Soil atmosphere exchange of carbonyl sulfide (COS) regulated by diffusivity depending on water-filled pore space
Soil atmosphere exchange carbonyl sulfide (COS) water-filled pore space
2010/1/15
The exchange of carbonyl sulfide (COS) between soil and the atmosphere was investigated for three arable soils from Germany, China and Finland and one forest soil from Siberia for parameterization in ...
