Isolated preparations of atrial specialized conduction fibers ("plateau" fibers) qualitatively resembled ventricular Purkinje fibers (false tendons) in their response to acetylstrophanthidin. Acetylstrophanthidin in concentrations of 1-3 X 10~ g/ml caused coupled, frequency-dependent transient depolarizations (TDs) in both types of fiber. In free-running strands of plateau fibers the TDs could ...
“any science seeks generalities; the aim is to transcend knowledge of particular cases by discovering general regularities or laws” (chesterman, 2001, p. 1). these were the words of chesterman whose paper has served as a typical example of numerous papers carried out on ‘translation universals’ since the mid-nineties. blum-kulka (1986) is among translation studies scholars who proposed ‘explici...
Isolating Effects of Total Dissolved Solids on Aquatic Life in Central Appalachian Coalfield Streams
Elevated levels of total dissolved solids (TDS) have been identified as stressors to aquatic life in Central Appalachian coalfield streams. At present there are no aquatic life water quality criteria for TDS in the primary coal-producing Central Appalachian states (KY, VA, WV). In all three states, mining-related impacts on aquatic life have been characterized using measures of benthic macroinv...
the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
Dairy farms in some arid areas around the world have to use drinking water that contained elevated total dissolved solids (TDS); however, very limited data is available concerning water TDS effects on health status and blood mineral levels of cattle. The aim of this study was to compare 3 dairy cattle groups in several dairy farms with different drinking water TDS: High (HTDS; >4000 ppm), Mediu...
The scalar boundary value problem (BVP) du dx2 −mu = −f (x, u) , x ∈ (0,∞) , u (0) = μ1, lim x→∞ u (x) = 0, for a second order differential equation on the infinite interval [0,∞) is considered. Under some natural assumptions it is shown that on an arbitrary finite grid there exists a unique three-point exact difference scheme (EDS), i.e., a difference scheme of which the solution coincides wit...
Effectively, two-dimensional (2D) closed films exhibiting in-plane orientational ordering (ordered shells) might be instrumental for the realization of scaled crystals. In them, ordered shells are expected to play the role of atoms. Furthermore, topological defects (TDs) within them would determine their valence. Namely, bonding among shells within an isotropic liquid matrix could be establishe...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
abstract: the present study is an attempt to find out cultural exophoric references in iranian high-school elt textbooks and touch stone series to compare the frequency of occurrence of such references in these books. the purpose is to find out which of the series of the books under investigation impose a greater referential burden on efl learners as far as their reading comprehension of the ...
Truth Diagrams, TDs, are a new diagrammatic notation for propositional logic. TDs provide: (1) representations of logical states of affairs and relations; (2) operators on such relations; (3) a test of the validity of derivations. A proof of one of de Morgan’s laws is given as an illustration of TDs. Truth Diagrams (TDs) were invented as part of a programme of research on the Representational E...
