Būvmateriālu rūpniecības attīstība Latvijā: Bolderājas silikātķieģeļu rūpnīcas piemērs (1952-1959)
2018
Darbā tika pētīta Latvijas PSR būvmateriālu rūpniecības attīstība uz lielākā Latvijas būvmateriālu uzņēmuma – Bolderājas silikātķieģeļu rūpnīcas – piemēra, laika posmā no 1952. līdz 1959. gadam. Pētījuma mērķis bija, analizējot arhīva un citus pieejamus avotus, konstatēt šīs tautsaimniecības sfēras un konkrētā uzņēmuma darbības attīstības galvenās tendences dotajā laika posmā. Pētījuma gaitā tika izpētīta Latvijas PSR būvmateriālu rūpniecības attīstība, īpašu uzmanību pievēršot izvēlētai rūpnīcai: izpētot tās struktūru, ražošanas procesu un produkciju, tās finansiālus radītājus, kā arī šīs rūpnīcas ražošanas procesā iesaistītā darbaspēka faktoru – tā darba un dzīves apstākļus. Kritiski izvē…
Reactions and countermeasures of medical oncologists towards the incoming COVID-19 pandemic: A whatsapp messenger-based report from the Italian colle…
2020
Background This descriptive, unplanned investigation has been undertaken to report reactions, attitudes and countermeasures which have been put in place and implemented by medical oncology units facing the COVID-19 outbreak in Southern Italy. Materials and methods Data have been retrospectively obtained from the time-related analysis of conversations via a WhatsApp messenger-based group chat between the medical directors belonging to the Italian College of Medical Oncology Directors. Overall number, intensity and time trend of conversations related to reactions during the 4 weeks of observation related to the crucial events which occurred between 24 February and 28 March, 2020 2020 are incl…
A global Canopy Water Content product from AVHRR/Metop
2020
Abstract Spatially and temporally explicit canopy water content (CWC) data are important for monitoring vegetation status, and constitute essential information for studying ecosystem-climate interactions. Despite many efforts there is currently no operational CWC product available to users. In the context of the Satellite Application Facility for Land Surface Analysis (LSA-SAF), we have developed an algorithm to produce a global dataset of CWC based on data from the Advanced Very High Resolution Radiometer (AVHRR) sensor on board Meteorological–Operational (MetOp) satellites forming the EUMETSAT Polar System (EPS). CWC reflects the water conditions at the leaf level and information related …
Physical activity and risk of atrial fibrillation in the general population : meta-analysis of 23 cohort studies involving about 2 million participan…
2021
Regular physical activity is well established to be associated with reduced risk of cardiovascular disease outcomes. Whether physical activity is associated with the future risk of atrial fibrillation (AF) remains a controversy. Using a systematic review and meta-analysis of published observational cohort studies in general populations with at least one-year of follow-up, we aimed to evaluate the association between regular physical activity and the risk of AF. Relevant studies were sought from inception until October 2020 in MEDLINE, Embase, Web of Science, and manual search of relevant articles. Extracted relative risks (RRs) with 95% confidence intervals (CIs) for the maximum versus the …

Optical properties of Ge-oxygen defect center embedded in silica films
2007
The photo-luminescence features of Ge-oxygen defect centers in a 100nm thick Ge-doped silica film on a pure silica substrate were investigated by looking at the emission spectra and time decay detected under synchrotron radiation excitation in the 10-300 K temperature range. This center exhibits two luminescence bands centered at 4.3eV and 3.2eV associated with its de-excitation from singlet (S1) and triplet (T1) states, respectively, that are linked by an intersystem crossing process. The comparison with results obtained from a bulk Ge-doped silica sample evidences that the efficiency of the intersystem crossing rate depends on the properties of the matrix embedding the Ge-oxygen defect ce…
Metal–Organic Frameworks (MOFs) Containing Adsorbents for Carbon Capture
2022
This research was funded by the European Regional Development Fund project “Innovation of the waste‐to‐energy concept for the low carbon economy: development of novel carbon capture technology for thermochemical processing of municipal solid waste (carbon capture and storage from waste—CCSW)”, grant number 1.1.1.1/19/A/013.
La Educación para la Sostenibilidad en Secundaria: El Antropoceno como herramienta para el tratamiento holístico de la problemática socioambiental
2021
El Antropoceno se ha propuesto como una nueva época caracterizada por la contrastada y generalizada influencia de la humanidad en el registro geológico. En el presente estudio se propone la utilización en Educación Secundaria de este nuevo concepto, propuesto por el Premio Nobel de Química Paul Crutzen, como herramienta para la concienciación del alumnado, ya que aúna todos los problemas socioambientales actuales y sus causas. En particular, esta investigación se centra en analizar su utilización en la enseñanza de las ciencias y en los materiales y libros de texto y diseñar, poner en práctica y evaluar propuestas fundamentadas de intervención didáctica para su uso que favorezcan actitudes …
Virtual proximity and transnational familyhood : a case study of the digital communication practices of Poles living in Finland
2020
The article presents a study of five Polish multicultural and multilingual families in Finland, and their engagement in digitally mediated family communication. Explored through an ethnographic inquiry into the in-app communication practices of Polish migrant mothers and children, the study contributes to the body of research at the intersection of new media and communication, transnational family and migration studies, and family multilingualism. Building on the concept of virtual proximity, which refers to the emotional closeness between individuals afforded by digital technologies and mobile communication, the study identifies four thematic patterns in participants’ practices in digital …
«Widrige Winde»: Der Abbruch der schonischen Expedition aus der Sicht des preußischen Gesandten, des Freiherrn Friedrich Ernst von Cnyphausen
2017
There are two interpretations of Peter the Great’s motives for refusing to land on the Swedish island of Schonen in historiography: that the tsar feared unforeseen military risks and that he did not trust his allies, Denmark and Great Britain. In this article, the author attempts to analyse in a more detailed way the reasons and consequences for the mistrust in the Northern Alliance by looking at communications by Baron Friedrich Ernst von Cnyphausen, the Prussian ambassador in Copenhagen. It is shown that the Russophobic hysteria which grasped the Danish royal court in September 1716 looks completely irrational when we consider parallel attitudes in the Prussian court. Cnyphausen does not …
