in this paper we study the module contractibility ofbanach algebras and characterize them in terms the conceptssplitting and admissibility of short exact sequences. also weinvestigate module contractibility of banach algebras with theconcept of the module diagonal.

introduction: we previously shown that microinjection of glutamate into the hdb of rat elicited cardiovascular depressive responses. microinjection of ap5 (an nmda receptor antagonist, 2.5 mm, 50 nl) and cnqx (an ampa receptor antagonist, 1 mm, 50 nl) caused no significant changes in the blood pressure and heart rate. microinjection of bicuculline (bmi: a gabaa receptor antagonist, 1 mm, 50 nl)...

This study compared the effects of adding upper-body sprint-intervals or continuous double poling endurance training to the normal training on maximal upper-body strength and endurance capacity in female cross-country skiers. In total, 17 female skiers (age: 18.1±0.8yr, body mass: 60±7 kg, maximal oxygen uptake (VO2max): 3.30±0.37 L.min-1) performed an 8-week training intervention. Here, either...

Abstract: We study the level spacing distribution P (S) of 2D real random matrices both symmetric as well as general, non-symmetric. In the general case we restrict ourselves to Gaussian distributed matrix elements, but different widths of the various matrix elements are admitted. The following results are obtained: An explicit exact formula for P (S) is derived and its behaviour close to S = 0...

In recent years special attention has been devoted to the problem of finding a copula, the diagonal section and opposite diagonal section of which are known. For given diagonal function and opposite diagonal functions, we provide necessary and sufficient conditions for the existence of a copula to have these functions as diagonal and opposite diagonal sections. We make use of techniques related...

Online detection of hydrodynamics of gas-solid fluidized bed was characterized using pressure fluctuations by cross recurrence plot (CRP) and cross recurrence quantification analysis (CRQA). Experiments were conducted in a lab scale fluidized bed of various particle sizes 150 μm, 280 μm and 490 μm at different gas velocities. Firstly, pattern changes of cross recurrence plot were discussed and ...

Quasi-orthogonal Hadamard matrices and Mersenne with two three values of the elements, used in digital data processing, are considered, as well basis error-correcting codes algorithms for transforming orthogonal images. Attention is paid to structures cyclic symmetries antisymmetries. The connection between symmetry antisymmetry on a orders equal prime numbers, products close primes, composite ...
