Evidence for the Presence of Separate Mechanisms Regulating Potassium and Sodium Distribution in Ulva Lactuca
1. The methods employed in these and preceding (25-27) studies were shown to allow analysis of true cellular sodium and potassium concentrations. 2. The rate of reaccumulation of potassium by potassium-deficient cells is independent of the presence or absence of sodium in the external medium. 3. Phenylurethane (10(-3)M), a photosynthetic and metabolic inhibitor, causes a marked progressive loss...
متن کاملMetabolic Factors Influencing the Sodium and Potassium Distribution in Ulva Lactuca
1. Methods for the use of the marine green alga, Ulva lactuca, in studies on electrolyte metabolism are described. 2. The effect of illumination and iodoacetate on the potassium and sodium content, as well as the influence of light and running sea water on the iodoacetate effect was investigated. The rate of exchange of cellular potassium ion for K(42) under conditions of light and dark at 20 a...
متن کاملMETABOLIC FACTORS INFLUENCING THE SODIUM AND POTASSIUM DISTRIBUTION IN ULVA LACTUCA* Bx GEORGE T. SCOTT AND HUGH
The uneven distribution of sodium and potassium between living cells and their environments has long attracted the interest of a great number of physiologists. Within the past 10 to 15 years particularly, a wealth of data has been accumulated in an attempt to elucidate the mechanisms by which the cell is able to accumulate potassium and at least partially exclude sodium. The notion that permeab...

مطالعه حاضر با هدف بررسی وجود رابطه ی ممکن میان هوشهای زبانی و منطقی زبان آموزان انگلیسی و تعداد و انواع مغلطه های زبانی و شواهد در متنهای استدلالی آنان انجام پذیرفته است.بدین منظور، 70 زبان آموز با سطح زبانی متوسط به بالا از دو موسسه زبان انگلیسی در ایران انتخاب شده و پرسشنامه های مزبوطه را تکمیل نموده و متنی استدلالی نوشتند. متون نوشته شده مورد بررسی قرار گرفته و نمرات پرسشنامه ها محاسبه شده ...
15 صفحه اولthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
