ith epiphytes found in aquatic and terrestrial habitats made up of various combinations of lower and higher plants. In aquatic habitats, i.e. lakes, rivers and the sea, there are always algae growing on each other. This not only applies to unicellular and filamentous forms and their colonies, but al

AC/DC/AC Converter with Power Electronics Current Modulator Used in DC Circuit for Renewable Energy exterieur" have fascinated curious minds since the earliest days of recorded history. Development of the scientific method with its emphasis on evidence obtained through experimentation-perhaps best illustrated in this field by Paul Bert‘s encyclopedic work-allowed several generations of our predece

Power Electronics Inverter with a Modified Sigma-Delta Modulator and an Output Stage Based on GaN E-o form condensed tannins. Some strains of . rhizobia are highly sensitive to flavolans in vitro and it has been suggested that nitrogen fixation by such strains is reduced or inhibited. This paper examines the relationship between symbiotic effectiveness and flavolan sensitivity for a large number o

On the cellular level, this is achieved by Na. extrusion or its vacuolar sequestration, decrease of the permeability of vacuolar and plasma membrane to Na. and, the last but not the least, better K. retention. Active Na. transport from cytosol to exterior or to

A speed observer based on an extended model of the induction machine for selected variables is applied in the control system for the induction machine. On the basis of the model developed for a
