It is well-known that a real analytic manifold X admits a complexification XC , a complex manifold that contains X as the fixed point set of an antiholomorphic involution. This can be seen as follows.The transition functions defining the manifold X are real-analytic local diffeomorphisms of Rn. The Taylor expansions of these transition functions can be considered as local biholomorphisms of Cn,...
Membranes offer remarkable attributes such as possessing small equipment footprints, having high efficiency and are environmentally friendly, with carbon membranes progressively investigated for gas separation applications. In this study, carbon tubular membranes for CO2 separationare prepared via the dip-coating method with P84 co-polyimide as the carbon precursor. The prepared membranes were ...
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...
The thermodynamics and molecular structure of a supramolecular complex between a tubular molecule, (P)-(12,8)-[4]cyclo-2,8-anthanthrenylene, and fullerene were investigated. The enthalpy-driven characteristics of the association were enhanced upon lengthening of the curved sp-carbon networks in the tubular molecule as a result of an increase in the C–C contact areas in addition to the emergence...
the current study conducted a finite element (fe) and experimental investigation on tubular channel angular pressing as a noble severe plastic deformation technique for producing ultrafine grained and nanostructure tubular components. to examine the effects of the tcap process on the strain distribution and deformation behavior, fe simulations were employed. the fe results demonstrated that equ...
Purpose: Study of benzene effects on kidney structure in mammals (mouse). Materials and Methods: The mice were studied in 3 groups: controls, solvent and treatment, at favorable laboratory conditions. Treatment mice were administered orally of benzene (0.1cc of benzene solution) for 10 days at a dose 1000 mg/kg of body weight. At the end of each period, the kidneys separated and fixed in paraf...
ISOKAWA, TODA and KUBOTA[1] etched fractured human dentin surfaces with a weak acid and observed that a part of the peritubular zone persisted as a recognizable tubular structure. The inner hypomineralized layer (SHROFF, WILLIAMSON and BERTAUD [2], SHROFF et al. [3] and TAKUMA [4]) which appeared in the tubular structure was assumed to play an important role. ISOKAWA et al. [1] also presumed di...
We proposed a 3D assembly technique and a perfusion cultivation system. The technique uses water transfer printing to fabricate a multilayer structured tubular tissue. By the perfusion cultivation system, this study was aimed to determine whether the tissue-engineered structure maintains the normally mechanical property as the development and function. In this work, we demonstrated that fabrica...
