The purpose of this paper was to review the theoretical underpinnings, major concepts, and methods of the typological approach. It was argued that the typological approach offers a systematic, empirically rigorous and reliable way to synthesize the nomothetic variable-centered approach with the idiographic case-centered approach. Recent advances in cluster analysis validation make it a promisin...

More than 20 different leukocyte or tissue antigens can presently be recognized; they belong to one complex system (HL-A) which is, from the genetic point of view, very similar to the H-2 system in the mouse. Another independent system consisting of two antigens has also been well defined, the Group Five system. The methods of defining these antigens, their tissue distri bution, and complex rel...

A generalized simplified model for describing the dynamic behavior of distributed parameter systems is proposed. The various specific characteristics of gain and phase angle of distributed parameter systems are investigated from frequency response formulation and complex plane representation of the proposed simplified model. The complex plane investigation renders some important inequality cons...

Two-phase flow regimes are affected by conduit position, alignment, geometry, flow direction, physical characteristics, and flow rate of each phase as well as the heat flux toward the boundaries. Due to the importance of two-phase flow, numerous regimes have been identified. The first step in studying micro-bubble formation inside a venturi tube is to recognize the type of flow regimes. In this...

in a systematic approach, we have investigated the effect of the presence of pb and sb in the bi site in a bscco (2223 phase) superconductor. there are some contradictory reports in substitution of sb in the bi site. some researchers report an increase in the tc of these materials. so, we have made an accurate stoichiometry of these superconductors and selected extra pure starting materials wit...

‎the problem of two-phase mhd boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. the effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. the governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...
