Zīdaiņu mirstības atšķirības Baltijas reģionā - Latvijā, Igaunijā, Lietuvā saistībā ar makroekonomiskajiem faktoriem no 2010. līdz 2016. gadam

2020

Tēmas pamatojums: Zīdaiņu un bērnu līdz 5 mirstība ir viens no galvenajiem valstu un bērnu labklājības rādītājiem, kas joprojām ir augsti pat vairākās attīstītās valstīs. Šī iemesla dēļ ir svarīgi monitorēt veicinošos faktorus, kas rada bērnu mirstības riskus agrīnā vecumā reģionālā perspektīvā, lai varētu tos mazināt un novērst. i,. Pētījumu sērija, ko veica LU MF Pediatrijas katedra Valsts pētījumu programmas ietvaros (1996 – 2010), identificēja cēloņsakarības starp bērnu mirstību un atsevišķiem socio- un makro-ekonomiskiem faktoriem Baltijas valstīs un atklāja atšķirības to savstarpējā mijiedarbā Latvijā, salīdzinājumā ar Lietuvu un Igauniju.

Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses

2021

The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…

Environmental drivers of lake profundal macroinvertebrate community variation : implications for bioassessment

2011

Assessing the conservation priority of freshwater lake sites based on taxonomic, functional and environmental uniqueness

2022

Aim We propose a novel approach that considers taxonomic uniqueness, functional uniqueness and environmental uniqueness and show how it can be used in guiding conservation planning. We illustrate the approach using data for lake biota and environment. Location Lake Puruvesi, Finland. Methods We sampled macrophytes and macroinvertebrates from the same 18 littoral sites. By adapting the original “ecological uniqueness” approach, we used distance-based methods to calculate measures of taxonomic (LCBD–t), functional (LCBD–f) and environmental (LCEH) uniqueness for each site. We also considered the numbers and locations of the sites needed to protect up to 70% of total variation in taxonomic, fu…

Enhancement by TNF-alpha of reactivation and replication of latent herpes simplex virus from trigeminal ganglia of mice.

1995

The influence of tumor-necrosis-factor-alpha (TNF-alpha), granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukine-1 (IL-1) and IL-3 on the in vitro reactivation frequency and replication rate of trigeminal ganglia of mice latently infected with herpes simplex virus (HSV) strain KOS was studied. It could be demonstrated that TNF-alpha and possibility GM-CSF, but not IL-1 and IL-3, enhanced the reactivation frequency and replication of HSV. Interferon alpha/beta (IFN alpha/beta) prevented reactivation and replication.

El Voto Económico en España

2015

En general se admite que el estado de la economía influye en los votantes y los políticos son plenamente conscientes de ello. Como dice Kiewiet se apoya al candidato que proporciona 'buenos tiempos', y se va en contra de quien gobierna en época de empeoramiento económico. Antes de otorgar el voto, los electores valoran el entorno político, social y económico del país. Qué les induce a inclinarse hacia un candidato se puede explicar a posteriori, estudiando aquello que determinó el sentido del voto en el pasado. El investigador puede observar un momento del tiempo (una o como mucho dos elecciones), o puede realizar un análisis longitudinal, con el deseo de aclarar qué influye en el votante c…

Dynamics in Interaction in Bilingual Team Teaching: Examples from a Finnish Preschool Classroom

2018

The current study aims to explore team teaching as it is manifested in bilingual interactional patterns in a preschool classroom in Finland. The data was collected in a preschool classroom where a bilingual pedagogy in Finnish (majority language) and Swedish (minority language) was implemented with monolingual Finnishspeaking children. Video recordings were made while two teachers with different predefined language roles were team teaching a class of 20 children during two circle times. A two-level analytic model was developed: on the macro level activity types, participant roles (type of leadership) and language allocation (the teachers’ relative use of Finnish and Swedish) were identified…

Workaholism and work engagement: how are they similar? How are they different? A systematic review and meta-analysis

2019

Workaholism and work engagement can be depicted, respectively, as the pathological and the healthy form of heavy work investment. In spite of their different definitions and outcomes on individual and organizational life, workaholism and work engagement are not clearly and adequately distinguished by scholars and researchers as they appear to show some overlapping features. The aim of this investigation was to meta-analyze available studies, selected by systematic review, on the relations between subdimensions of workaholism and work engagement. Thirty-five studies were eligible for analysis. Associations emerged between Working Excessively and Absorption (g = .34), Working Compulsively and…

The importance of phytoplankton production for carbon budgets in a semiarid floodplain wetland

2011

Phytoplankton production (PP) in wetlands is not measured as often as that of macrophytes. A three year-study during a period of sustained high flooding was undertaken in a central Spanish floodplain wetland (Las Tablas de Daimiel National Park) to determine net PP, its spatial heterogeneity and controlling factors, and compare it with primary production in macrophyte communities. This enabled us to estimate carbon budgets for each community. All PP variables showed high spatial and temporal variability among sites, resulting in low coherence even when flooding connected all sites. Net PP corresponded to 25- 36% of submerged plant production and 3-10% of helophyte production. Net PP was con…

L'économie matérielle de la France (1830-2015). L'histoire d'un parasite ?

2018

This article explores the long-term dynamics of material use in France over a period of 185 years. It is based on material flow accounts that are perfectly consistent with the standards of Material Flows Analysis at the national economic scale. This work - which covers domestic extraction, imports and exports - is the first long-term study of material flows for France, with annual and national data for most of the period. Our database allows us to study the evolution of French metabolism during the industrialization of the country, together with the increasing dependence on abiotic materials. We highlight a singular metabolic trajectory: that of a state that benefits from successive world-s…
