this study was conducted to evaluate different nutrient solutions effects on agria potato mini-tubers production under aeroponic system. the experiment was conducted in the laboratory and greenhouse of ardabil sabalan behparvar company in 2013. four recommended nutrient solutions including: lommen and struik (1992), kang and han (2005), otazu (2010) and hoagland and arnon (1950) were used in a ...

We analyze the well-observed flare and coronal mass ejection (CME) from 1 October 2011 (SOL2011-10-01T09:18) covering the complete chain of effects - from Sun to Earth - to better understand the dynamic evolution of the CME and its embedded magnetic field. We study in detail the solar surface and atmosphere associated with the flare and CME using the Solar Dynamics Observatory (SDO) and ground-...

This paper presents a mechanism that may modify the extinction law for SNIa observed at higher redshift. Starting from the observations that (1) SNIa occur predominantly in spiral galaxies, (2) star-formation ejects ISM out of the plane of spirals, (3) star-formation alters the extinction properties of the dust in the ISM, and (4) there is substantially more star-formation at higher redshift, I...

BACKGROUND Many local authorities in England and Wales have reduced street lighting at night to save money and reduce carbon emissions. There is no evidence to date on whether these reductions impact on public health. We quantified the effect of 4 street lighting adaptation strategies (switch off, part-night lighting, dimming and white light) on casualties and crime in England and Wales. METH...

and Summary Impulse trains in sustaining and dimming fibers of crayfish optic lobe (in situ) were elicited with sinusoidal extrinsic current and sine wave illumination. Extrinsic currents and currents derived from PSPs were used to compute the time course of the spike train with an adaptive integrate-and-fire model. The neurons exhibit variations in gain and spike timing precision related to th...

For the elderly, sensory impairments increase vulnerability and limit the quality of life. Dimming eyesight and failing hearing can reduce physical, functional, emotional, and social well-being. Visual and hearing impairments decrease independence in performing the activities of daily living, getting from place to place, or communicating with others. Isolation, depression, and poorer social rel...

conclusions the inhibition of mini-puberty period in male rats was demonstrated to have an effect on their testicular function to some extent. results serum t and lh levels peaked at two hours after birth, while fsh peaked at hour 0, and bilateral testicular weight peaked at four hours after birth. the rats that underwent ether inhalation five minutes after birth had markedly reduced serum horm...

b a ckground:  nutrition status is an important constituent of health in an elderly and  evaluation  of  these  groups  are  necessary  for  development  of  treatment protocols. the study aimed to estimate the prevalence of malnutrition with mini nutritional assessment (mna)  tool  in  the  elderly living in  nursing homes.  in addition, the association of mna results and functional status was...
