Bilinguals have reported that they have a stronger emotional experience in their native language (L1) than in their second language (L2). Behavioral studies are inconclusive about this question. However, studies that used skin conductance levels as a dependent variable are clearer about this effect: participants elicit a stronger skin conductance response on emotional and taboo words in L1 comp...

The generation of Alfvénic Poynting flux in the central plasma sheet and its polar distribution at low altitude are studied using three dimensional global simulations of the solar wind-magnetosphere-ionosphere interaction. A 24-hour event simulation (4-5 Feb 2004) driven by solar wind and interplanetary magnetic field data reproduces the global morphology of Alfvénic Poynting flux measured by t...

In recent experiments, synaptically isolated neurons from rat cortical culture, were stimulated with periodic extracellular fixed-amplitude current pulses for extended durations of days. The neuron's response depended on its own history, as well as on the history of the input, and was classified into several modes. Interestingly, in one of the modes the neuron behaved intermittently, exhibiting...

Heat switches, known also as thermal switches, are devices that switch as needed between roles as good thermal conductors and good thermal insulators. When one is installed in the heat-conduction path between a warm, heat-producing component and a heat sink, the change in thermal conductance it affords can control the temperature of the component. Heat switches can passively control the tempera...

The present study was aimed to evaluate a biological solution to improve peppermint plant growth and production in the salt-affected soil. The experiment was arranged in a factorial experiment based on completely randomized design with three replications in the greenhouse under controlled conditions (28/15 oC in day/night). Three levels of methyl jasmonate (0, 75 and 150 µM) and four leve...

Salinity is a complex phenomenon that involves not just an osmotic effect, but also toxic ion effects and nutritional imbalance. In order to evaluate the effects of severity and duration of sodium chloride stress on some biochemical and photosynthesis parameters of tobacco a factorial experiment was conducted using a randomized completely block design with three replication with using a hydropo...

stomata are closed by moisture stress, reducing carbon assimilation and yield production with dry land agriculture. relative 13c to 12c molar ratio assimilation by a plant is a function of time stomata remain open during plant life time, itself a function of moisture stress. the purpose of this study was to test the existence of any relationship between stomatal conductance and assimilation rat...

cystic fibrosis (cf) is the most common inherited disorder in caucasian populations, with over 1400 cystic fibrosis transmembrane conductance regulator (cftr) mutations. the type of mutations and their distributions varies widely between different countries and/or ethnic groups. seventy iranian cystic fibrosis patients were screened for the cftr gene mutation using arms/pcr (amplification refra...

We have investigated the ATP-induced permeabilization of rat peritoneal mast cells using three different techniques: (a) by measuring uptake of fluorescent membrane and DNA marker dyes, (b) by voltage-clamp measurements using the patch-clamp technique, and (c) by measurements of exocytosis in response to entry of Ca2+ and GTP gamma S into permeabilized cells. In the absence of divalent cations ...
