In many household surveys, geographically clustered households report unit values of foods, which when corrected for quality effects and for measurement error, indicate the underlying spatial variation in prices, and can be matched to variation in demand patterns so as to estimate price elasticities. A 1979 household survey from the Cote d'Ivoire is used to estimate price elasticities for beef,...
Stress shapes memory. Depending on the timing of the stress exposure facilitating and impairing effects of stress are reported on how much is learned and remembered. Beyond such stress-induced changes in the quantity of memory, recent research suggests that stress also affects the contribution of multiple memory systems to performance. Under stress, rigid 'habit' memory gets favored over more f...

nitrogen (n) affects adversely the tobacco yield quantity and quality as it increases yield, chlorine and nicotine contents, but decrease potassium content. this experiment was aimed at optimization of (the balance between) n concentration in leaf, stem and root to increase both yield quantity and quality (high potassium, low chlorine and medium nicotine contents) using artificial neural networ...
Clomiphene citrate (CC) has an adverse effect on the quality and quantity of cervical mucus (CM). Poor cervical mucus has been reported in 15% of CC-treated women. CC exhibits estrogen agonist and antagonist activities. Antiestrogenic activity affecting the endocervical glands is theorized to cause a decrease in cervical mucus quality and quantity. An experimental study was performed to as...
The high quality and quantity seed production in old saxual shrubs are essential for regeneration and sustainable development of saxual forests in desert areas.
