Tentative Recommendation on Terminology and Definitions in Respiratory Physiology: Résumé of the Isott Consensus Session 1992
1994
1 The use of small letters for the symbols “p” (partial pressure), “s” (saturation) and “c” (concentration) (e.g. pO2, sO2, cO2) follows recommendations of the IFCC and IUPAC [4]. This supports the use of contemporary word processing systems and mostly eliminates the need to use subscripts (except for chemical valencies: e.g. O2, CO2, H2CO3 etc.). The potential risk of misinterpretations and double meanings is reduced also (e.g. “cO2” [oxygen concentration] v.s. “CO2” [carbon dioxide] and “sO2” [oxygen saturation] v.s. “sO2” [sulfur dioxide]). 2 The symbol shall include the site of measurement or description, e.g. paO2 (arterial O2 partial pressure), svO2 (mixed venous oxygen saturation), o…
Structure of longitudinal chromomagnetic fields in high energy collisions
2014
We compute expectation values of spatial Wilson loops in the forward light cone of high-energy collisions. We consider ensembles of gauge field configurations generated from a classical Gaussian effective action as well as solutions of high-energy renormalization group evolution with fixed and running coupling. The initial fields correspond to a color field condensate exhibiting domain-like structure over distance scales of order the saturation scale. At later times universal scaling emerges at large distances for all ensembles, with a nontrivial critical exponent. Finally, we compare the results for the Wilson loop to the two-point correlator of magnetic fields.
Robust l2-gain control for 2D nonlinear stochastic systems with time-varying delays and actuator saturation
2013
Abstract This paper is concerned with the problems of stability analysis and l2-gain control for a class of two-dimensional (2D) nonlinear stochastic systems with time-varying delays and actuator saturation. Firstly, a convex hull representation is used to describe the saturation behavior, and a sufficient condition for the existence of mean-square exponential stability of the considered system is derived. Then, a state feedback controller which guarantees the resulting closed-loop system to be mean-square exponentially stable with l2-gain performance is proposed, and an optimization procedure to maximize the estimation of domain of attraction is also given. All the obtained results are for…
Retās un apdraudētas augu sugas jūrmalas zilpodzes (Eringium maritimum L.) pavairošana in vitro un audu fenolu saturs atkarībā no barotnes sastāva
2016
Jūrmalas zilpodze (Eryngium maritimum L.) ir Latvijā reta un apdraudēta suga, kura ir ierakstīta Latvijas Sarkanās grāmatas 1. kategorijā. Latvijā jūrmalas zilpodzes izplatību ierobežo piemērotu biotopu trūkums un sēklu mazā dīgtspēja. Zilpodzei ir liela nozīme Eiropas tradicionālajā medicīnā, jo tā satur dažādus bioaktīvus savienojumus ar daudzveidīgu farmakoloģisko aktivitāti. Darba mērķis bija uzsākt jūrmalas zilpodzes augu audu kultūru un izmēģināt šīs sugas mikropavairošanas metodes, kā arī noteikt kopējā fenolu satura izmaiņas atkarībā no barotnes sastāva. Lai iesāktu kultūru, kā sākotnējo eksplantu izmantoja sēklas, kuras diedzēja aseptiskos apstākļos. Jūrmalas zilpodzes mikropavairo…

Source shape and data analysis procedure effects on hydraulic conductivity of a sandy-loam soil determined by ponding infiltration runs
2017
Performing ponding infiltration runs with non-circular sources could represent a good means to sample completely an area of interest. Regardless of the shape of the source, predicting the expected reliability of the collected data by infiltrometers should facilitate soil hydraulic characterisation and also allow a more conscious use of the field data. The influence of the shape of the infiltration source (i.e., circular or square) and the analysis procedure of the steady-state infiltration data on the saturated hydraulic conductivity, Ks, of a sandy-loam soil was tested in this investigation. Circular and square surfaces sampled with the pressure infiltrometer (PI) yielded similar estimates…
Characterization of inductors in partial saturation for SMPS applications
2017
The exploitation of partially saturated inductors in Switching Mode Power Supply (SMPS) is a key strategy for reducing the size of SMPS and increasing their power density [1]. However an accurate characterization and modellization of each inductor is needed for a correct design and control of the SMPS [2]. Most of inductors' datasheets only indicate the nominal inductance at low current. Anyway, when the inductor is subjected to a higher current, the value of the inductance is lessened. Moreover, inductance meters often actuate their measurements at no or moderate DC bias. In this work we describe the realization of an automated test bench (Fig. 1) for characterizing an inductor under varia…
Biotic and abiotic soil properties influence survival of Listeria monocytogenes in soil
2013
International audience; Listeria monocytogenes is a food-borne pathogen responsible for the potentially fatal disease listeriosis and terrestrial ecosystems have been hypothesized to be its natural reservoir. Therefore, identifying the key edaphic factors that influence its survival in soil is critical. We measured the survival of L. monocytogenes in a set of 100 soil samples belonging to the French Soil Quality Monitoring Network. This soil collection is meant to be representative of the pedology and land use of the whole French territory. The population of L. monocytogenes in inoculated microcosms was enumerated by plate count after 7, 14 and 84 days of incubation. Analysis of survival pr…
La delimitación del concepto de daño moral: un estudio de la cuestión en el ordenamiento jurídico español.
2021
El presente estudio tiene como objetivo realizar una aproximación al concepto de daño moral en el derecho español porque, a diferencia del daño patrimonial, el Código Civil no proporciona un concepto sobre él. Para la articulación de un concepto de daño moral es necesario analizar los supuestos de reconocimiento legal, la interpretación que los órganos judiciales han hecho y el tratamiento proporcionado en los Principios de derecho contractual europeo y de derecho de daños europeo. El trabajo finaliza con una valoración sobre la actual configuración del daño moral. The present study aims to make an approximation to the concept of non-pecuniary damage in Spanish law because, unlike property …
The oxygen status of arterial human blood
1990
The oxygen status of arterial human blood is described at least by four variables: Oxygen partial pressure (pO2, mmHg), oxygen saturation (sO2, %), hemoglobin content (cHb, g/dL) and oxygen content (cO2, mL/dL). Beside perfusion, however, the oxygen supply of all organs is decisively determined by the mean capillary pO2 which itself is primarily dependent on the arterial cO2. Therefore, the oxygen availability (cardiac output x caO2, mL/min) may be described by the cO2 value in arterial blood or those variables who determine the latter one. The diagnostic significance of the O2 variables of the oxygen status consequently increases in the order of pO2, sO2 (cHb) and cO2. In arterial blood, o…
