Monotony Based Imaging in EIT
2010
We consider the problem of determining conductivity anomalies inside a body from voltage‐current measurements on its surface. By combining the monotonicity method of Tamburrino and Rubinacci with the concept of localized potentials, we derive a new imaging method that is capable of reconstructing the exact (outer) shape of the anomalies. We furthermore show that the method can be implemented without solving any non‐homogeneous forward problems and show a first numerical result.
Stefan-Boltzmann Radiation on Non-convex Surfaces
1997
We consider the stationary heat equation for a non-convex body with Stefan–Boltzmann radiation condition on the surface. The main virtue of the resulting problem is non-locality of the boundary condition. Moreover, the problem is non-linear and in the general case also non-coercive and non-monotone. We show that the boundary value problem has a maximum principle. Hence, we can prove the existence of a weak solution assuming the existence of upper and lower solutions. In the two dimensional case or when a part of the radiation can escape the system we obtain coercivity and stronger existence result. © 1997 by B.G. Teubner Stuttgart-John Wiley & Sons, Ltd.
LABOUR AND ECONOMIC GROWTH THROUGH EDUCATION AND RESEARCH IN LATVIA
2012
The structure of Latvian economy and distribution of employees within it during last years has changed. Dealing with study of population, one can find young people share continuous decline and labour mean age increase, but in situation of economic slowdown Latvia also face challenge to develop knowledge-based economy. One of the means of helping to achieve the goal of becoming competitive and knowledge-based economy is through an investment in human capital. To ensure sustainable development there is a need to balance between social and economical growth using available resources. The theoretical concepts have shown that further growth has to be built on innovation, diffusion and adoption o…
PRESCHOOL TEACHER’S ATTITUDE TO ENTERPRISE IN PRESCHOOL INSTITUTION
2014
Research on enterprise is known all over the Globe. Enterprise in education can serve as an opportunity for improving quality and effectiveness of education; it can be realized as added value. The Latvian National Development Plan shows that the education system task is to reach an educated man competitive labour market to develop people’s initiative, enterprise and creativity needed for the sustainable development of society. In the education sector is always an issue of how and whether the existing education system prepare new generation needs for adult life, pace of work and the changing environment etc. Question is: do we have preschool teachers who think and work in enterprise manner …
Application of Environmental Management Systems (EMS) to Natural Parks and reserves
2006
Natural parks and reserves have to face problems concerning the conservation of their natural resources. Citizens and firms often perceive the institution of new protected areas more as a bind or a restriction to their activities than an added value of the territory. Following the principles of sustainable development, it is necessary to integrate the environmental protection with the needs of neighbouring urban areas and production sites. The implementation of an Environmental Management System (EMS) according to international standards (ISO 14001, EMAS) can support the Park administration in their complex management activities. This paper analysed the criticisms related to the application…
Baroja como materia de sus libros: para una lectura de <em>El árbol de la ciencia</em> (1911) en clave autobiográfica
2014
The aim of this paper is to analyze the characteristics of Barojian autobiographical literature and to check if there are enough arguments to state that El arbol de la ciencia is Pio Baroja’s most autobiographical novel. For that purpose, and after going over the scholar’s theories about the autobiographical side of Barojian literature, the article focuses on the study of autobiographical characters in El arbol de la ciencia and attempts to place this novel within its «autobiographical space». Lastly, it suggests a possible interpretation of the double value that we attribute to the main character of the novel, Andres Hurtado, as an autobiographical character and as a generational symbol of…
L’erraticità della centralità. Valori simbolici e valori monetari nella città di Palermo
2017
The center of the city could be considered as the urban meta-sign from which each part of the city takes his urban monetary significance, and it can also be joined to the isomorphic chain linking Zero, Vanishing Point and Money. The center of the city is naturally erratic and follows the urban transformation, producing monetary differentials corresponding to differentials of quality of the localization. The case study of Palermo is analyzed showing the creation of the center of the city, its translation and its (monetary) evaluation in the contemporaneous city.
The Genealogy of Personal Names: towards a more productive method in historical onomastics
2011
It is essential to combine genealogical and collective biographical approaches with network analysis if one wants to take full advantage of the evidence provided by (hereditary) personal names in historical and linguistic onomastic research. The naming practices of rural families and clans from the 18th to the 20th century can bring us much fresh information about their enduring attitudes and values, as well as about other mentalities of everyday life. Personal names were cultural symbols that contained socially shared meanings. With the help of genealogical method it is possible to obtain a more nuanced understanding of these past naming practices, for example by comparing the conventions …
Adaptive radiation along a thermal gradient: preliminary results of habitat use and respiration rate divergence among whitefish morphs.
2014
Adaptive radiation is considered an important mechanism for the development of new species, but very little is known about the role of thermal adaptation during this process. Such adaptation should be especially important in poikilothermic animals that are often subjected to pronounced seasonal temperature variation that directly affects metabolic function. We conducted a preliminary study of individual lifetime thermal habitat use and respiration rates of four whitefish (Coregonus lavaretus (L.)) morphs (two pelagic, one littoral and one profundal) using stable carbon and oxygen isotope values of otolith carbonate. These morphs, two of which utilized pelagic habitats, one littoral and one …
Polymorphism of the transcription factor 7-like 2 gene (TCF7L2) interacts with obesity on type-2 diabetes in the PREDIMED study emphasizing the heter…
2016
Nutrigenetic studies analyzing gene–diet interactions of the TCF7L2-rs7903146 C > T polymorphism on type-2 diabetes (T2D) have shown controversial results. A reason contributing to this may be the additional modulation by obesity. Moreover, TCF7L2-rs7903146 is one of the most influential variants in T2D-genetic risk scores (GRS). Therefore, to increase the predictive value (PV) of GRS it is necessary to first see whether the included polymorphisms have heterogeneous effects. We comprehensively investigated gene-obesity interactions between the TCF7L2-rs7903146 C > T polymorphism on T2D (prevalence and incidence) and analyzed other T2D-polymorphisms in a sub-sample. We studied 7018 PREDIMED …
