The Diagnosis of Disease by Element Analysis
1988
The elemental composition of the human body images in principle the elements of the periodic system. In the literature, about 80 elements are reported to occur in the human body and the number is expected to increase by the introduction of methods more sensitive in detection. The elemental composition in reference man as published (1) is summarized in tab. 1. From the major elements in reference man, the determination of the elements nitrogen, calcium, phosphorus, potassium, sodium, chlorine and magnesium are of importance for the diagnosis of diseases. The importance of the element determination for the diagnosis of diseases is also documented by the numbers of element determinations done …
Assessment of workflow feature selection on forest LAI prediction with sentinel-2A MSI, landsat 7 ETM+ and Landsat 8 OLI
2020
The European Space Agency (ESA)’s Sentinel-2A (S2A) mission is providing time series that allow the characterisation of dynamic vegetation, especially when combined with the National Aeronautics and Space Administration (NASA)/United States Geological Survey (USGS) Landsat 7 (L7) and Landsat 8 (L8) missions. Hybrid retrieval workflows combining non-parametric Machine Learning Regression Algorithms (MLRAs) and vegetation Radiative Transfer Models (RTMs) were proposed as fast and accurate methods to infer biophysical parameters such as Leaf Area Index (LAI) from these data streams. However, the exact design of optimal retrieval workflows is rarely discussed. In this study, the impact of…
Student voice in learning assessment: a pathway not yet developed at university
2012
During 2009/2010, the current research was conducted with the aim of analysing student and teaching staff on regarding student participation in assessment. A content analysis of 76 subject outlines was carried out, and then 40 member of the teaching staff and 614 university students were surveyed. The results of the content analysis prove there is a shortage of information about and programming for student participation in assessment. Durante el curso 2009/2010 se llevó a cabo esta investigación con el objetivo de analizar la opinión y perspectiva que profesores y estudiantes universitarios tienen sobre la participación de estos últimos en el proceso de evaluación. Se realizó un análisis de…
Algorithms as legal norms: About extending traditional legal safeguards for regulations enacted by public administrations to the algorithms used by p…
2020
En este trabajo se argumenta que los algoritmos empleados por parte de las Administraciones públicas para la adopción efectiva de decisiones han de ser considerados reglamentos por cumplir una función material estrictamente equivalente a la de las normas jurídicas, al reglar y predeterminar la actuación de los poderes públicos. Adicionalmente se estudia cómo, una vez asumida esta naturaleza jurídica reglamentaria de estas herramientas de programación, se deducen consecuencias jurídicas respecto de cómo han de realizarse los procedimientos de elaboración y aprobación de estos algoritmos, la necesidad de que los mismos estén debidamente publicados como normas jurídicas que son o la exigencia …
Optical Quality Comparison between Spherical and Aspheric Toric Intraocular Lenses
2014
Purpose To measure and compare the optical quality of spherical and aspheric toric intraocular lenses (IOLs). Methods Wavefront aberrations of AcrySof Toric and IQ Toric IOLs (Alcon Laboratories) for different powers were measured at 3- and 5-mm pupils by Nimo TR0805 instrument. The Zernike coefficients of trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration were evaluated. The point spread functions (PSFs) of each IOL evaluated were calculated from the wavefront aberrations. The PSF images also were calculated from the IOL wavefront aberrations, adding the cornea's aberrations to simulate the optical quality after their implantation. Results Spherical toric IOLs showed…
Promoting youth entrepreneurship and employability through non-formal and informal learning: the Latvia case
2019
This paper presents some results of the research on ‘Adult education resources to reduce youth unemployment’, which is a part of the project ‘Implementation of the European agenda for adult learning’. The research applies a mixed-method approach (quantitative and qualitative data analysis). The purpose of the paper is to identify the most/least-efficient non-formal and informal learning methods, forms, and initiatives to promote youth entrepreneurship and employability in Latvia as well as to show the relationship between the profile of young adults and their opinion on these methods, forms, and initiatives. The findings show that the young adults stressed the importance of cooperation with…
Design, development and validation of a system for automatic help to medical text understanding
2020
Abstract Objective The paper presents a web-based application, SIMPLE, that facilitates medical text comprehension by identifying the health-related terms of a medical text and providing the corresponding consumer terms and explanations. Background The comprehension of a medical text is often a difficult task for laypeople because it requires semantic abilities that can differ from a person to another, depending on his/her health-literacy level. Some systems have been developed for facilitating the comprehension of medical texts through text simplification, either syntactical or lexical. The ones dealing with lexical simplification usually replace the original text and do not provide additi…

En las últimas décadas, la Economía Social ha experimentado una importante expansión como modelo económico que ofrece nuevas respuestas a los problemas socioeconómicos del sistema colocando a las personas y sus necesidades por delante del capital y los beneficios (Monzón & Chaves, 2020; Chaves & Monzón, 2018 y Chaves, Savall & Monzón, 2016).Dentro de las organizaciones de la Economía Social, podemos señalar a las empresas de inserción como empresas sociales que en la situación actual de crisis socioeconómica y precarización laboral generalizada, en el marco de las políticas activas de empleo, destacan como instrumentos que luchan contra la exclusión de personas con dificultades de integraci…
Optogenetically blocking sharp wave ripple events in sleep does not interfere with the formation of stable spatial representation in the CA1 area of …
2016
During hippocampal sharp wave/ripple (SWR) events, previously occurring, sensory inputdriven neuronal firing patterns are replayed. Such replay is thought to be important for plasticity-related processes and consolidation of memory traces. It has previously been shown that the electrical stimulation-induced disruption of SWR events interferes with learning in rodents in different experimental paradigms. On the other hand, the cognitive map theory posits that the plastic changes of the firing of hippocampal place cells constitute the electrophysiological counterpart of the spatial learning, observable at the behavioral level. Therefore, we tested whether intact SWR events occurring during th…
Preparation of Biomolecule Microstructures and Microarrays by Thiol-ene Photoimmobilization
2009
A mild, fast and flexible method for photoimmobilization of biomolecules based on the light-initiated thiol-ene reaction has been developed. After investigation and optimization of various surface materials, surface chemistries and reaction parameters, microstructures and microarrays of biotin, oligonucleotides, peptides, and MUC1 tandem repeat glycopeptides were prepared with this photoimmobilization method. Furthermore, MUC1 tandem repeat glycopeptide microarrays were successfully used to probe antibodies in mouse serum obtained from vaccinated mice. Dimensions of biomolecule microstructures were shown to be freely controllable through photolithographic techniques, and features down to 5 …
