The Universidad Científica del Sur or Scientific University of the South is a private institution of higher education, located at 19 km south from the city of Lima, nearby Pantanos de Villa Reserved Zone. The university was founded and recognized in 1998 by education representatives, leaded by José Carlos Dextre. It started activities by offering Medicine and Systems Engineering programmes. Their curriculum was characterized by personalized education and early introduction to the career.The university had presented an important growth in population and in academic offer. Today, it has 18 bachelor and 13 master’s degrees programmes, as well as several specialization courses. Wikipedia.

Objectives. To characterize the supply, demand and the gap of medical specialists in facilities of the Ministry of Health of Peru (MINSA) at the national, regional and specialty type levels. Materials and methods. Observational, descriptive study through which we calculated the supply of medical specialists using secondary sources of MINSA. The analysis of the demand for medical specialists was based on two methodologies: the need for specialists according to the guidelines of classification of the health facilities and according to the epidemiological and demographic profile. The arithmetic difference between the estimated demand and the supply was the procedure used to calculate the gap of medical specialists. Results. The Ministry of Health has a total supply at the national level of 6,074 medical specialists of which 61.5% belong to the clinical specialties, 33.2% to the surgical specialties, 4.9% specialities related to aid to diagnosis and treatment and 0.4% to public health specialties. According to the categorization guideline there is a total demand of 11,176 medical specialists and according to the epidemiological and demographic profile of 11,738. The national estimated gaps found are similar in both methods, although they differ widely across regions and by type of specialty. At the regional level, the gaps are greater in Loreto, Piura, Puno and Madre de Dios when estimating the defficit in relation to the supply. Regarding the speciality, the gap is greater in the four basic specialties: gynecology and obstetrics, pediatrics, internal medicine and general surgery. Conclusions. There is a waid gap between supply and demand of medical specialists at the national and regional levels, as a whole representing approximately 45% of the current offer, regardless of the estimation method.

We discuss the influence of surface viscoelasticity effects on the effective properties of materials such as effective bending stiffness of plates or shells. Viscoelastic properties in the vicinity of the surface can differ from the properties of the bulk material. This difference influences the behavior of nanostructural elements. In particular, the surface viscoelastic stresses are responsible for the size-depended dissipation of nanosized structures. Using the extension of the Gurtin-Murdoch model and the correspondence principle of linear viscoelasticity we derive the expressions of the stress and couple stress resultant tensors for shear deformable plates and shells. © 2012 Elsevier Ltd.

Nonlinear micropolar continuum model allows to describe complex micro-structured media, for example, polycrystals, foams, cellular solids, lattices, masonries, particle assemblies, magnetic rheological fluids, liquid crystals, etc., for which the rotational degrees of freedom of material particles are important. The constitutive equations of the hyperelastic nonlinear micropolar continuum can be expressed using the strain energy density depending on two strain measures. In the case of inelastic behavior the constitutive equations of the micropolar continuum have more complicated structure, the stress and couple stress tensors as well as other quantities depend on the history of strain measures. In what follows we discuss the constitutive equations of the nonlinear micropolar continuum using strain rates. © 2014 Elsevier Ltd. All rights reserved.

The distribution of the anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitides (AAV) is not uniform across geographical regions and ethnic and racial groups, suggesting that genetic and environmental factors affect the pathogenesis of these diseases. In addition, genetic factors affect not only the clinical syndrome phenotypes and their prognosis, but also ANCA specificity; these data suggest that AAV may need reclassification. Several genes have been evaluated, including ANCA targets and those of the immune system, for example co-stimulatory molecules, signaling regulators, cytokines, Fc and other receptors, and other proteins. This article provides a review of genetic factors affecting the pathogenesis and prognosis of AAV. Further studies to determine the effect of genetic factors on the clinical syndrome phenotypes and ANCA specificity need to be performed across different ethnic groups. © Springer Science+Business Media 2014.

Below we discuss the derivation of the governing nonlinear shell equations taking into account the surface stresses. The surface effects are significant for the modeling of some structures as nanofilms, nanoporous materials and other nano-size structures. In particular, the surface stresses are responsible for the size effect, i.e. dependence of the material properties on the specimen size. The theory of elasticity with surface stresses is applied to the modeling of shells with nano-scaled thickness. It will be shown that the resultant stress and couple stress tensors can be represented as a sum of two terms. The first term in the sum depends on the stress distribution in the bulk material while the second one relates to the surface stresses. Hence, the resultant stress and couple stress tensors are linear functions with respect to the surface stresses. As an example the effective stiffness properties of a linear elastic Cosserat shells taking into account the surface stresses are presented. © 2011 Elsevier Ltd. All rights reserved.
