These lecture notes give a short introduction to ideas shared by classical theory of geometries and modern model theory. This course is not on stability theory and thus all the non-trivial results from stability theory are replaced by stronger assumptions, except three: Shelah’s finite equivalence relation theorem, one consequence of splitting and the fact that ∞ -definable groups in models of ...

Psoriasis is a chronic, immune-mediated, systemic, inflammatory disorder characterized by skin plaques and, often, nail disease and arthritis that contribute to reduced quality of life. Psoriatic arthritis—a heterogeneous, inflammatory, musculoskeletal can cause permanent damage both peripheral axial joints—is the most common comorbidity psoriasis. Axial occurs in 25% 70% patients with PsA, som...

An innovative axial hydrocyclone separator was designed in which a guide vane installed to replace conventional tangential inlet, potentially aggravating inlet turbulence. The characteristics of velocity distribution, concentration and pressure distribution inside the were obtained through numerical simulation turbulent flow oil water. results showed that field presented good symmetry, eliminat...

The present study utilizes an analytical method to formulate the three lowest modal frequencies of axially-loaded notched beam through both crack location and load level in a specific format that can be used in existing frequency-based crack-identification methods. The proposed formula provides a basis to shift into two states, one with axial loading and the other without any loading whatsoever...

In this paper it is attempted to investigate the behavior of an inviscid flow in the meridional plane of an axial flow compressor. For this purpose the 3-D unsteady Euler equations in cylindrical coordinate are averaged in tangential direction. Therefore, the equations are reduced to a 2-D system. By averaging the tangential component of momentum equation, a blade force will result. Axial and r...

The basic functions of a typical satellite, distilled to their quintessence, include only the absorption, processing, and subsequent re-radiation of photons. To this end, spacecraft components need only be able to exchange energy – which tends to be dichotomized into power and information – and transmit the occasional force or torque. Perfectly adequate and efficient mechanisms for accomplishin...

In view of non-specific toxicity of most chemotherapeutic agents against normal cells, the development of targeted chemotherapy is warranted. Efficient targeting of chemotherapeutic drugs to the cancerous area could be of great benefit for patients with advanced or metastatic tumors. Targeted cytotoxic peptide conjugates are hybrid molecules composed of a peptide carrier which binds to receptor...
