Ruolo del rumore ambientale in sistemi complessi di natura biologica
2010
La Fisica dei Sistemi Complessi ha recentemente assunto un ruolo sempre più importante nella descrizione dei sistemi biologici a causa delle interazioni, sia deterministiche sia rumorose o “randomiche”, di tali sistemi con l’ambiente. La presenza del rumore diviene particolarmente rilevante nella trattazione dei sistemi biologici in ambito medico. In questo lavoro vengono presentati due diversi sistemi: i) un modello di dinamica di popolazioni che descrive lo sviluppo delle cellule tumorali responsabili della Leucemia Mieloide Cronica (CML); ii) un modello stocastico che riproduce la crescita di batteri in alimenti di origine animale. Nel primo sistema viene utilizzato un approccio Monte Ca…
Influence of a Thiolate Chemical Layer on GaAs (100) Biofunctionalization: An Original Approach Coupling Atomic Force Microscopy and Mass Spectrometr…
2013
International audience; Widely used in microelectronics and optoelectronics; Gallium Arsenide (GaAs) is a III-V crystal with several interesting properties for microsystem and biosensor applications. Among these; its piezoelectric properties and the ability to directly biofunctionalize the bare surface, offer an opportunity to combine a highly sensitive transducer with a specific bio-interface; which are the two essential parts of a biosensor. To optimize the biorecognition part; it is necessary to control protein coverage and the binding affinity of the protein layer on the GaAs surface. In this paper; we investigate the potential of a specific chemical interface composed of thiolate molec…

Omalizumab outcomes for up to 6 years in pediatric patients with severe persistent allergic asthma
2021
BACKGROUND: Various studies have assessed omalizumab outcomes in the clinical practice setting but follow-up and/or number of patients included were limited. We aim to describe the long-term outcomes of pediatric patients with severe persistent allergic asthma receiving omalizumab in the largest real-life cohort reported to date. METHODS: ANCHORS was a multicenter, observational, retrospective cohort study conducted in 25 Pediatric Allergy and Pulmonology units in Spain. We collected data of patients < 18 years and initiating omalizumab between 2006 and 2018, from the year prior to omalizumab initiation to discontinuation or last available follow-up. The primary outcome was the evolution of…
Inhibition of denitrification and N2O emission by urine-derived benzoic and hippuric acid
2006
Abstract Hippuric acid (HA) in cattle urine acts as a natural inhibitor of soil N2O emissions. As HA concentration varies with diet, we determined critical HA levels. We also tested the hypothesis that the inhibition occurs because the HA breakdown product benzoic acid (BA) inhibits denitrification rates. During a 64-day incubation, we quantified emissions from artificial urine varying in HA, BA and glycine (Gly) concentrations, added to a sandy pasture soil. Increasing HA concentration from 0.4 to 5.6 mmol kg−1 soil significantly decreased the average N2O flux by 54%. At 3.9 mmol kg−1 soil, denitrification levels were 50% reduced for BA as compared to Gly. We conclude that HA inhibits both…
Time resolved emission at 1.3 μm of a single InAs quantum dot by using a tunable fibre Bragg grating
2013
Photoluminescence and time resolved photoluminescence from single metamorphic InAs/GaAs quantum dots (QDs) emitting at 1.3 mu m have been measured by means of a novel fibre-based characterization set-up. We demonstrate that the use of a wavelength tunable fibre Bragg grating filter increases the light collection efficiency by more than one order of magnitude as compared to a conventional grating monochromator. We identified single charged exciton and neutral biexciton transitions in the framework of a random population model. The QD recombination dynamics under pulsed excitation can be understood under the weak quantum confinement potential limit and the interaction between carriers at the …
Mazākumtautību 6.klases skolēnu mutvārdu monoloģisko prasmju pilnveide latviešu valodas stundās
2020
Maģistra darbā tiek pētīta mazākumtautību 6.klases skolēnu mutvārdu monoloģisko prasmju pilnveide latviešu valodas stundās. Maģistra darba autore ir Nadežda Račkova. Šis pētījums ir aktuāls, jo pētījumu par skolēnu monoloģisko prasmju pilnveidošanu mazākumtautību skolēniem latviešu valodas apguvē ir samērā maz. Savukārt prasības, mazākumtautību skolēniem veidojot monoloģiskus izteikumus latviešu valodā (katrā valodas apguves posmā), ir daudz augstākas nekā svešvalodā, tās ir tuvu prasībām dzimtajā valodā. Tomēr didaktiskie veidi, kā izpildīt šīs prasības, atšķiras no dzimtajā un svešvalodu metodikā pieņemtajiem. Pētījuma mērķis ir izpētīt mazākumtautību 6. klases skolēnu mutvārdu monoloģisk…
Carbon Monoxide Activation by a Molecular Aluminium Imide: C−O Bond Cleavage and C−C Bond Formation
2020
Anionic molecular imide complexes of aluminium are accessible via a rational synthetic approach involving the reactions of organo azides with a potassium aluminyl reagent. In the case of K 2 [( NON )Al(NDipp)] 2 ( NON = 4,5‐bis(2,6‐di iso propylanilido)‐2,7‐di‐tert‐butyl‐9,9‐dimethyl‐xanthene; Dipp = 2,6‐di iso propylphenyl) structural characterization by X‐ray crystallography reveals a short Al‐N distance, which is thought to be due primarily to the low coordinate nature of the nitrogen centre. The Al‐N unit is highly polar, and capable of the activation of relatively inert chemical bonds, such as those found in dihydrogen and carbon monoxide. In the case of CO, uptake of two molecules of …
Metodologiczne aspekty badań regionu śląskiego w okresie międzywojennym z socjologicznej perspektywy
2021
The paper demonstrates the methodologic aspect of the Polish sociologic research on the Silesian region in the interwar period. Referring to pre-sociologic and sociologic research, it depicts the methodologic foundations and intellectual perspectives that were conceptualised by ludwik krzy-wicki and constitute the cognitive basis for the construction of the knowledge about Silesia – they are defined as the object analysis current and the subject analysis current. The article illustrates the evolution of research methods – from the questionnaire technique, via the existing materials analy-sis, to Florian Znaniecki’s id method and the monographic method used in field research. it touches upon…
