comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولChitosan nanocapsules of tarragon essential oil with low cytotoxicity and long-lasting activity as a green nano-larvicide
Frequent use of synthetic larvicides has led to the development of resistance in many species of mosquitoes as well as risk of environmental pollution. Recently, encapsulating essential oils (EOs) in surfactants or polymers is being employed as an approach to control the volatility of EOs as green larvicides. In this research, components of tarragon (Artemisia dracunculus) essential oil were id...
متن کاملLong - lasting , long - range detection
We examined the time course of threshold reduction in the Gabor lateral masking paradigm (Polat and Sagi 1993). Contrast detection thresholds were measured (2AFC) for a brieey presented (36 msec) foveal Gabor signal (GS), preceded by a presentation (90 msec) of two high-contrast GS anked masks, with Stimulus Onset Asynchrony (SOA) varying from 0 to 16,290 msec. Using target-to-mask separations ...
متن کاملLong-lasting potentiation and depression without presynaptic activity.
1. Long-term potentiation (LTP) and long-term depression (LTD) require a rise in intracellular Ca2+ concentration ([Ca2+]i) in the postsynaptic CA1 pyramidal neuron to activate Ca-dependent biochemical processes. This rise in [Ca2+]i is a necessary trigger for the induction of LTP and LTD, but it is unclear if concurrent presynaptic activity is required for their induction or expression. 2. We ...
متن کاملA case of long-lasting misdiagnosed lymphangioma circumscriptum masquerading as dermatitis
Lymphangioma circumscriptum is a rare benign lymphatic malformation, clinically characterized by clusters of translucent vesicles. Uncommon manifestations such as verruciform or zosteriform have also been reported in the literature, yet eczematous-like presentation is extremely rare. The present study describes the case of a young woman with a 16-year history of an exudative eczematous-like pla...
