SMOS REFLEX 2003: L-band emissivity characterization of vineyards
2005
The goal of the Soil Moisture and Ocean Salinity mission over land is to infer surface soil moisture from multiangular L-band radiometric measurements. As the canopy affects the microwave emission of land, it is necessary to characterize different vegetation layers. This paper presents the Reference Pixel L-Band Experiment (REFLEX), carried out in June-July 2003 at the Vale/spl grave/ncia Anchor Station, Spain, to study the effects of grapevines on the soil emission and on the soil moisture retrieval. A wide range of soil moisture (SM), from saturated to completely dry soil, was measured with the Universitat Polite/spl grave/cnica de Catalunya's L-band Automatic Radiometer (LAURA). Concurre…
Nature-Inspired Effects of Naturally Occurring Trace Element-Doped Hydroxyapatite Combined with Surface Interactions of Mineral-Apatite Single Crysta…
2022
Innovative engineering design for biologically active hydroxyapatites requires enhancing both mechanical and physical properties, along with biocompatibility, by doping with appropriate chemical elements. Herein, the purpose of this investigation was to evaluate and elucidate the model of naturally occurring hydroxyapatite and the effects of doped trace elements on the function of normal human fibroblasts, representing the main cells of connective tissues. The substrates applied (geological apatites with hexagonal prismatic crystal habit originated from Slyudyanka, Lake Baikal, Russia (GAp) and from Imilchil, The Atlas Mountains, Morocco (YAp)) were prepared from mineral natural apatite wit…
Looking at cell mechanics with atomic force microscopy: Experiment and theory
2014
This review reports on the use of the atomic force microscopy in the investigation of the mechanical properties of cells. It is shown that the technique is able to deliver information about the cell surface properties (e.g., topography), the Young modulus, the viscosity, and the cell the relaxation times. Another aspect that this short review points out is the utilization of the atomic force microscope to investigate basic questions related to materials physics, biology, and medicine. The review is written in a chronological way to offer an overview of phenomenological facts and quantitative results to the reader. The final section discusses in detail the advantages and disadvantages of the…
GPU-accelerated integral imaging and full-parallax 3D display using stereo-plenoptic camera system
2019
Abstract In this paper, we propose a novel approach to produce integral images ready to be displayed onto an integral-imaging monitor. Our main contribution is the use of commercial plenoptic camera, which is arranged in a stereo configuration. Our proposed set-up is able to record the radiance, spatial and angular, information simultaneously in each different stereo position. We illustrate our contribution by composing the point cloud from a pair of captured plenoptic images, and generate an integral image from the properly registered 3D information. We have exploited the graphics processing unit (GPU) acceleration in order to enhance the integral-image computation speed and efficiency. We…
Digital holographic microscopy as a screening technology for diabetes
2019
Label-free quantitative phase imaging (QPI) is the hallmark of digital holographic microscopy (DHM). One of the most interesting medical applications of QPI-DHM is that it can be used to analyze illnesses in which the refractive index or/and the morphology of cells/tissues are distorted, from the acquisition of a single image. In this contribution, we obtain the phase maps of red blood cells (RBCs) samples of patients suffering from diabetes mellitus type 1 (DM1) by using a DHM. Our experimental results show that the measured phase values are significantly different between control non-diabetic and diabetic patients. The high correlation coefficient between the phase and the glycated hemogl…
Covid-19 Anxiety Relationship with Emotional Intelligence and Burnout Clinical Subtypes Among Organizational Staff
2022
Maģistra darba “Covid-19 trauksmes saistība ar emocionālo intelektu un klīniskajiem izdegšanas apakštipiem organizāciju darbinieku vidū” mērķis ir noskaidrot vai un kādas saistības pastāv Covid-19 trauksmes, emocionālā intelekta un klīnisko izdegšanas apakštipu starpā. Papildus iepriekš minētajam, darba mērķis ir arī pārbaudīt hipotēzi, ka darbinieki, kuri strādā daļēji vai pilnībā attālināti, izjūt lielāku Covid-19 trauksmi, salīdzinot ar darbiniekiem, kuri ikdienā strādā klātienē. Pētījumā piedalījās 130 organizāciju darbinieki vecumā no 20 līdz 55 gadiem, no kuriem 56 strādā klātienē, 42 – attālināti, bet 32 - hibrīdajā modelī. Izmantotas trīs aptaujas - “Izdegšanas klīnisko apakštipu ap…

Digital holographic microscopy for diabetes screening
2016
A digital holographic microscope operating in telecentric mode could be used to diagnose diabetes and evaluate long-term glycemic control in patients with diabetes.
Latvian Migrants in Great Britain: ‘The Great Departure’, Transnational Identity and Long Distance Belonging
2019
AbstractThis chapter explores the transnational aspects of identity and the long distance belonging of Latvian migrants in Great Britain. In particular, it focuses on the discourses and practices of long distance belonging to Latvia. The article is based on a comparative analysis of The Emigrant Communities of Latvia survey data as well as semi-structured interviews with Latvian migrants in Great Britain. The analytical sections are organised so as to discuss the three main analytical contexts of long distance belonging: ethno-cultural, political and social. In the ethno-cultural context, migrants who identify themselves as ethnic Latvians rediscover and strengthen their links to the Latvia…
Introducción a la Ciencia Política y de la Administración. Tema 1b. El Estado absoluto.

Introducción a la Ciencia Política y de la Administración. Tema 1b. El Estado y su evolución histórica. El Estado absoluto. La aparición del Estado-nación constituyó un largo y complicado proceso. A fines del siglo XVI, la Reforma y la Contrarreforma habían dividido a Europa en una serie de Estados territoriales, católicos o protestantes. Biografía: La formación del Estado Moderno.
