Over the last decade, numerous papers have presented the use of dry electrodes capable of acquiring electroencephalogram (EEG) signals through hair. A few of these dry electrode prototypes have even progressed from labbased EEG acquisition to commercial sales. While the field has improved rapidly as of late, most dry electrodes share a number of shortcomings that limit their potential real worl...

abstract to optimal use of available water, irrigation scheduling is important to over scarcity of water resources in arid and semi-arid area. in this research to estimate of maximum allowable deficit (or: management allowed depletion) and irrigation scheduling of fodder mays based on canopy-air temperature difference, a field study was conducted in agricultural faculty of karaj. the lower limi...

abstract salinity stress is among the major barriers to plant production in many parts of the world, especially in arid and semi-arid areas. jasmonates are one of the newest plant growth regulators that reduce the damages caused by environmental stresses. in this study, the effects of salinity and methyl jasmonate on some morphological traits of chamomile including root and shoot lengths, fresh...

An updated version of the semi-analytical model for describing the steady-state concentration in the atmospheric boundary layer is presented here. Two inversion methods of the Laplace transform are tested: the Gaussian Quadrature scheme and the Fixed-Talbot method. The model takes into account settling velocity, removal (wet and dry deposition), and first order chemical reactions. The capabilit...

U.S. consumers spend more than $11 billion a year on cat and dog food, according to the Pet Food Institute. And pet food manufacturers compete for these dollars by trying to make their products stand out among the many types of dry, moist, and semi-moist foods available. Pet food packaging carries such descriptive words as "senior," "premium," "super-premium," "gourmet," and "natural." These te...

BACKGROUND Sjögren's Syndrome is an autoimmune exocrinopathy characterised by lymphocytic infiltration of exocrine glands in multiple sites, with dry mouth as a primary presenting symptom. Although quantitative studies have shown the negative impact of both dry mouth and Sjögren's Syndrome on patients' quality of life, no qualitative diary and interview study has been undertaken to examine the ...
