Abstract This paper aims to examine the influence of gravity on a thermoelastic micro‐elongated layer when piezoelectric is above it, utilizing theory Lord–Shulman (L–S) and also model dual‐phase‐lag (DPL). A partial differential equation was transformed into an ordinary using normal mode analysis. Aluminum epoxy numerical computations are carried out, results presented in graphical format. The...

In this work, a new model for porothermoelastic waves under fractional time derivative and two delays is utilized to study temperature increments, stress the displacement components of solid fluid phases in media. The governing equations are presented Lord–Shulman theory with thermal relaxation time. finite element method has been adopted solve these due complex formulations problem. effects pa...

Resumen Este artículo aborda la práctica profesional en formación inicial del profesorado como un proceso de aculturación basado apropiación saberes adaptados al contexto escolar. Para ello, se moviliza tipología profesionales Shulman (1986, 1987) con el fin identificar aquellos que le son propios a cultura profesorado. Se estudia caso 3 parejas practicante-supervisor provenientes centros Chile...

Anti-gamma globulin autoantibodies or rheumatoid factors have been detected in the serum of approximately 70-80 per cent. of patients with rheumatoid arthritis (RA) (Ziff, 1957; Glynn and Holborow, 1960; Singer, 1961; Vaughan and Butler 1962), and antinuclear autoantibodies or factors have been detected in approximately 30 per cent. of patients with the disease (Alexander, Bremner, and Duthie, ...

Abstract We develop bicategory theory in univalent foundations. Guided by the notion of univalence for (1-)categories studied Ahrens, Kapulkin, and Shulman, we define study bicategories. To construct examples bicategories a modular fashion, displayed , an analog 1-categories introduced Ahrens Lumsdaine. demonstrate applicability this prove that several interest are univalent. Among these catego...

Shulman (1987) defined pedagogical content knowledge as the required to transform subject-matter into curricular material and representations. This paper presents results of an exploratory case study that examined a secondary teacher’s sine cosine values in both clinical professional settings discern characteristics mathematical schemes facilitate their transformation learning artifacts experie...
