Zīdaiņu aprūpe akūta gastroenterīta gadījumā un vispārējie preventīvie pasākumi
2022
Bakalaura darba tēma: “Zīdaiņu aprūpe akūta gastroenterīta gadījumā un vispārējie preventīvie pasākumi”. Tēmas aktualitāti nosaka tas, ka akūta diareja jeb akūts gastroenterīts ir viena no visbiežāk sastopamajām bērnu infekcijas slimībām pasaulē un ir nopietns slogs sabiedrības veselībai kopumā. Latvijā, pēdējo 10 gadu laikā, novērots reģistrēto zarnu infekciju gadījumu skaita pieaugums. Kā viens no biežākajiem cēloņiem tiek minēts smags gastroenterīts bērniem, kas patērē veselības aprūpes resursus, pazemina pacienta un viņa vecāku dzīves kvalitāti, kā arī rada nopietnu sociāli ekonomisko slogu. Statistikas dati liecina, ka Latvijā katru gadu reģistrēto zarnu infekciju skaits sasniedz vairā…
Closed tank pneumatic press application to improve Sauvignon Blanc wine quality and nutraceutical properties
2019
The machines used in the winemaking process directly affect the quality of wine and its nutraceutical properties. Grapes-pressing is a very important step in winemaking as it may promote the presence and/or absence of enzymatic processes on the must, leading to the creation of different products in terms of chemical composition, starting from the same grapes. The aim of the study was to compare two different pressing systems of Sauvignon Blanc grapes using an innovative pneumatic discontinuous closed tank press in two operating modes: the traditional pressing mode in presence of oxygen and the inert pressing mode, performed through grapes pressing under inert gas with nitrogen recovery. Che…
Vortex dynamics in rotating counterflow and plane Couette and Poiseuille turbulence in superfluid Helium
2008
An equation previously proposed to describe the evolution of vortex line density in rotating counterflow turbulent tangles in superfluid helium is generalized to incorporate nonvanishing barycentric velocity and velocity gradients. Our generalization is compared with an analogous approach proposed by Lipniacki, and with experimental results by Swanson et al. in rotating counterflow, and it is used to evaluate the vortex density in plane Couette and Poiseuille flows of superfluid helium.
Muscle‐tendon morphology and function following long‐term exposure to repeated and strenuous mechanical loading
2020
We mapped structural and functional characteristics of muscle‐tendon units in a population exposed to very long‐term routine overloading. Twenty‐eight military academy cadets (age: 21.00 ± 1.1 yrs; height: 176.1 ± 4.8 cm; mass: 73.8 ± 7.0 kg) exposed for over 24 months to repetitive overloading were profiled via ultrasonography with a senior subgroup of them (n = 11; age = 21.4 ± 1.0 yrs; height = 176.5 ± 4.8 cm; mass = 71.4 ± 6.6 kg) also tested while walking and marching on a treadmill. A group of eleven ethnicity‐ and aged‐matched civilians (age = 21.6 ± 0.7 yrs; height = 176.8 ± 4.3 cm; mass = 74.6 ± 5.6 kg) was also profiled and tested. Cadets and civilians exhibited similar morphology…
The crater lake of Ilamatepec (Santa Ana) volcano, El Salvador: insights into lake gas composition and implications for monitoring
2019
We here present the first chemical characterization of the volcanic gas plume issuing from the Santa Ana crater lake, a hyper-acidic crater lake (pH of − 0.2 to 2.5) in north-western El Salvador. Our results, obtained during regular surveys in 2017 and 2018 using a Multi-GAS instrument, demonstrate a hydrous gas composition (H2O/SO2 ratios from 32 to 205) and SO2 as the main sulfur species (H2S/SO2 = 0.03–0.1). We also find that gas composition evolved during our investigated period, with the CO2/SO2 ratio decreasing by one order of magnitude from March 2017 (37.2 ± 9.7) to November 2018 (< 3). This compositional evolution toward more magmatic (SO2-rich) compositions is interpreted in the c…

Baveno VII – Renewing consensus in portal hypertension
2022
To expand on the work of previous meetings, a virtual Baveno VII workshop was organised for October 2021. Among patients with compensated cirrhosis or compensated advanced chronic liver disease (cACLD – defined at the Baveno VI conference), the presence or absence of clinically significant portal hypertension (CSPH) is associated with differing outcomes, including risk of death, and different diagnostic and therapeutic needs. Accordingly, the Baveno VII workshop was entitled “Personalized Care for Portal Hypertension”. The main fields of discussion were the relevance and indications for measuring the hepatic venous pressure gradient as a gold standard, the use of non-invasive tools for the …

High-spectral-resolution Fabry-Pérot interferometers overcome fundamental limitations of present volcanic gas remote sensing techniques
2023
Remote sensing (RS) of volcanic gases has become a central tool for studying volcanic activity. For instance, ultraviolet (UV) skylight spectroscopy with grating spectrographs (GS) enables SO2 (and, under favourable conditions, BrO) quantification in volcanic plumes from autonomous platforms at safe distances. These measurements can serve volcanic monitoring and they cover all stages of volcanic activity in long measurement time series, which substantially contributes to the refinement of theories on volcanic degassing. Infrared (IR) remote sensing techniques are able to measure further volcanic gases (e.g., HF, HCl, CO2, CO). However, the employed Fourier transform spectrometers (FTSs) are…
Patrimoine Immatériel et identité culturelle. Le repas gastronomique des Français reconnu par l'UNESCO
2011
International audience; Comment faire comprendre au monde que l'on peut demander, auprès de l'UNESCO, l'inscription de la France au patrimoine mondial de l'humanité, au titre du patrimoine immatériel gastronomique, sans pour autant exprimer le moindre désir de suprématie sur les autres cultures alimentaires ? Quels ressorts identitaires, par exemple humains, techniques et culturels, mettre en valeur, dans un souci de préservation et de transmission d'un domaine d'excellence, au bénéfice de l'humanité ? Sous quel angle dominant et en quels termes élémentaires, fondateurs, donner sens et forme à la démarche ? Ainsi peut-on énoncer, quelques unes, des problématiques foncières rencontrées d'emb…
