Sirds ritma variabilitātes maiņas kuņģa sekrēcijas cefāliskās fāzes laikā
2015
Darbs veltīts autonomās nervu sistēmas eferento ietekmju izpētei uz kuņģa sekrēciju cefāliskās fāzes laikā. Lai novērtētu šīs eferentācijas kāpumus un kritumus, klīniskajā fizioloģijā tiek piedāvāts izmantot SRV novērtēšanas metodi. Vēlējāmies noskaidrot SRV maiņas, novērtējot desmit klīniski veselu pieaugušu cilvēku SRV parametrus „rīta miera” un „laboratorijas miera” apstākļos, kā arī cefāliskās fāzes laikā – 20 minūtēs pēc MMB. Secinājumi: dažādu viena indivīda SRV datu noturīgums ir atšķirīgs, bet cikla garuma atšķirības nepārsniedz 1,5%, RMSSD – 5%. Savukārt „rīta miera” un ”laboratorijas miera” datu salīdzinājums liecina, ka tie atšķiras nenozīmīgi. Eksperimenta ar MMB rezultāti apsti…
Estimation de la différence de température entre la forêt et les sites ouverts dans le Jura
2017
International audience; Cet article porte sur la modélisation statistique des différences qui apparaissent entre la température observée en forêt et en site ouvert. Pour ce faire, nous utilisons un corpus de 29 couples de stations situées à faible distance l'une de l'autre dans les deux milieux et localisés dans le Jura (France). Les températures minimales (tn) et maximales (tx) ont été acquises de décembre 2014 à octobre 2015. La modélisation est fondée sur un modèle de régression où les variables explicatives sont deux variables temporelles relatives aux conditions atmosphériques (amplitude journalière et écart à la normale 1981-2010 des températures). En moyenne, les tn sont plus élevés …
Microneedle-Based Delivery: An Overview of Current Applications and Trends
2020
Microneedle arrays (MNA) are considered as one of the most promising resources to achieve systemic effects by transdermal delivery of drugs. They are designed as a minimally invasive, painless system which can bypass the stratum corneum, overcoming the potential drawbacks of subcutaneous injections and other transdermal delivery systems such as chemical enhancers, nano and microparticles, or physical treatments. As a trendy field in pharmaceutical and biomedical research, its applications are constantly evolving, even though they are based on very well-established techniques. The number of molecules administered by MNA are also increasing, with insulin and vaccines administration being the …
Inkluderende læringsmiljø - fra teori til praksis : En kvantitativ studie av hvilken betydning ulike implementeringsdrivere har hatt i satsingen «Ink…
2018
Masteroppgave ledelse ORG917 - Universitetet i Agder 2018 Temaet i denne masteroppgaven er implementering, som handler om å omsette teori til praksis (Fullan, 2007). Satsingen «Inkluderende læringsmiljø» startet i 2014 og omfatter barnehager, skoler og PP-tjenester i kommunene Iveland, Lillesand, Songdalen, Søgne og Vennesla. Den er forankret i et felles samarbeid «Inkluderende læringsmiljø og pedagogisk refleksjon» i de syv kommunene i Knutepunkt Sørlandet (Region Kristiansand fra 01.01.18), og er en oppfølging av regionplan Agder 2020. Formålet med satsingen «Inkluderende læringsmiljø» er å etablere en felles pedagogisk plattform for arbeidet med læringsmiljø, slik at alle barn og unge få…
Disentangling directional and fluctuating asymmetry in a genome-wide association study.
2018
8 pages; International audience; Although directional and fluctuating asymmetry have been frequently assessed independently, they are indeed associated concepts both in theory and in practice. However, they can be difficult to disentangle in genome-wide association studies, where the appropriate shape statistics are not fully developed. Although the usage of Procrustes distances to overcome this problem may be tempting, this does not reliably help to identify the underlying genetic components of directional and fluctuating asymmetries. Here, similarities and differences among different approaches have revealed that the genetic component of the skull asymmetry in this population of mice is m…
Excessive Daytime Sleepiness in Obstructive Sleep Apnea Patients Treated With Continuous Positive Airway Pressure: Data From the European Sleep Apnea…
2021
Excessive daytime sleepiness (EDS) is a symptom of obstructive sleep apnea (OSA) that resolves under treatment with continuous positive airway pressure (CPAP). In some patients, sleepiness persists despite CPAP treatment. We retrospectively analyzed data on subjective residual EDS, assessed as an Epworth Sleepiness Scale score (ESS) >10, in patients from the European Sleep Apnea Database (n = 4,853, mean age +/- SD 54.8 +/- 11.8 years, 26.1% females), at baseline and at the first visit (median follow-up: 5 months, interquartile range 3-13). An ESS > 10 occurred in 56% of patients at baseline and in 28.2% of patients at follow-up. Residual EDS was analyzed in 2,190 patients (age: 55.1 +/- 12…
Slimību nosaukumi, to darināšana latviešu tautasdziesmās
2022
Maģistra darba temats ir Slimību nosaukumi, to darināšana latviešu tautasdziesmās. Darba mērķis: apzināt un aprakstīt, kādi slimību nosaukumi minēti latviešu tautasdziesmās, pētīt un skaidrot to cilmi un vārddarināšanas paņēmienus. Mērķa sasniegšanai izvirzīto uzdevumu realizācija apstiprināja hipotēzi: slimību nosaukumu kā substantīvu latviešu tautasdziesmās nav daudz, bet vairāk ir adjektīvu, kas raksturo cilvēka veselības stāvokli, kā arī substantīvu, kas apzīmē kādu no orgāniem vai cilvēka ķermeņa daļām savienojumā ar verbu sāpēt. Darba gaitā tika izmantotas šādas pētnieciskās metodes: kontekstuālā pieeja, komparatīvā metode, sistematizēšana un analizēšana. Maģistra darbs sastāv no teor…
Fate of organic pollutants after sewage sludge spreading on agricultural soils: a 30-years field-scale recording
2006
Le DOI mentionné dans l'article 10.2166/WPT.2007.008 ne fonctionne pas; International audience; Toxic organic compounds, such as the surfactants linear alkylbenzene sulfonates (LAS) and nonylphenol polyethoxylates (NPE), Polycyclic aromatic hydrocarbons (PAH) and residues derived from plastics (PAE-phthalates) end up in sewage sludge. In order to evaluate and quantify the potential environmental risks associated with the xenobiotic introduction into biological life cycle, the EU BIOWASTE project (QLK5-CT-2002-01138) devotes one task to the study of the fate of xenobiotic in a sandy soil after sludge spreading on a 30-year field-scale record experiment. Experimental maize crop fields from Bo…
Characterization of IP-Based Communication for Smart Grid Using Software-Defined Networking
2018
The smart grid (SG) approach is based on a strong interaction between the network communication infrastructure and the power grid. Usually the management of the infrastructure is done by the distribution system operators (DSOs) that are worried about the increasing managing complexity due to the presence of increasing number of distributed energy resources and electrical vehicles. The use of software-defined networking (SDN) may simplify the network configuration and management for DSO, as highlighted from previous research works. The objective of this paper is to introduce and characterize an internet protocol (IP)-based communication architecture with specialized SDN bridges operating als…
PQ and Harmonic Assessment Issues on Low-Cost Smart Metering Platforms: A Case Study
2020
This paper presents a feasibility study on how to implement power quality (PQ) metrics in a low-cost smart metering platform. The study is aimed at verifying the possibility of implementing PQ monitoring in distribution networks without replacing existing smart metering devices or adding new modules for PQ measurements, thus zeroing the installation costs. To this aim, an electronic board, currently used for remote energy metering, was chosen as a case study, specifically the STCOMET platform. Starting from the specifications of this device, the possibility of implementing power quality metrics is investigated in order to verify if compliance with standard requirements for PQ instruments ca…
