Wpływ rywalizacji i wykluczenia na rozwój zrównoważonej mobilności miejskiej
2017
W ramach miejskiej polityki transportowej stosuje się różne narzędzia mające na celu zachęcenie mieszkańców do wyboru bardziej zrównoważonych od samochodu sposobów przemieszczania się. W artykule główny nacisk położono na znaczenie rywalizacji i wykluczenia jako cech dóbr składających się na miejskie systemy transportowe w kształtowaniu atrakcyjności bardziej zrównoważonych sposobów przemieszczania się osób w miastach. Studia literaturowe oraz analiza porównawcza pozwoliły na przedstawienie instrumentów służących rozwojowi zrównoważonej mobilności miejskiej wraz z oczekiwanymi i potencjalnymi ich efektami.
Educación para la sostenibilidad y educación ambiental
2010
En este trabajo se analizan algunos de los obstáculos que están dificultando la implicación de diferentes sectores sociales en la adopción de las medidas necesarias para hacer frente a la actual situación de emergencia planetaria. En particular, analizamos la supuesta confrontación entre educación ambiental y educación para la sostenibilidad. Intentaremos mostrar que no existen razones para dicho antagonismo, sino que responde a malentendidos que es urgente deshacer, porque entorpecen la necesaria convergencia de esfuerzos para lograr una formación ciudadana que haga comprender la gravedad de la situación y prepare para participar en la toma de decisiones. Dans cet article nous analysons qu…
EVALUATION OF BIODEGRADABILITY ON POLYSPARTAMIDE-POLYLACTIC ACID BASED NANOPARTICLES BY CHEMICAL HYDROLYSIS STUDIES POLYMER DEGRADATION AND STABILITY
2015
Here, the synthesis of two graft copolymers based on α,β-poly(N-2-hydroxyethyl)-D,L-aspartamide (PHEA) and poly(lactic acid) (PLA), the O-(2-aminoethyl)-O′-galactosyl polyethylene glycol (GAL-PEG-NH2) or the methoxypolyethylene glycol amine (H2N-PEG-OCH3) is described. Starting from the obtained PHEA-PLA-PEG-GAL and PHEA-PLA-PEG copolymers, polymeric nanoparticles were prepared by high pressure homogenization–solvent evaporation method. To demonstrate their biodegradability as a function of the matrix composition, a chemical stability study was carried out until 21 days by incubating systems in two media mimicking physiological compartments (pH 7.4 and pH 5.5). The degradability of both nan…

Genetic variability at αs2-casein gene in Girgentana dairy goat breed
2014
Casein genes are highly polymorphic and the high degree of variability has qualitative and quantitative effects on milk composition thereby affecting chemical, physical and technological properties of goat milk. The aim of this work was to evaluate the genetic polymorphisms of the αs2-casein (CSN1S2) gene in the endangered Girgentana dairy goat breed in order to assess the genotypes distribution, as it is known genotype influences technological and nutritional milk properties. The study was performed on 207 sample of Girgentana goat breed, analysed with different PCR protocols. The most frequent alleles was A (0.722), followed by F (0.225), C (0.051) and E (0.002) while B, D and 0 alleles w…
Ground and first excited electronic state interaction of FAD with some β-carboline derivatives
1987
Abstract The spectrophotometric and thermodynamic properties of molecular complexes of flavine adenine dinucleotide (FAD) with some dihydro β-carboline derivatives have been investigated in aqueous solution. The molecular associations have been examined by means of electronic absorption spectra, since in each a new charge-transfer band has been located, and also the variation of the fluorescence emission of FAD on the solutions has been observed. The formation constants for the molecular complexes were determined from absorption data, using the Foster-Hammick-Wardley method. The quenching fluorescence phenomena observed in FAD is related to the concentration of the dihydro β-carboline deriv…
WDR45 Gene and Its Role in Pediatric Epilepsies
2021
AbstractWD repeat domain 45 (WDR45) gene has been increasingly found in patients with developmental delay (DD) and epilepsy. Previously, WDR45 de novo mutations were reported in sporadic adult and pediatric patients presenting iron accumulation, while heterozygous mutations were associated with β-propeller protein-associated neurodegeneration (BPAN), a subtype of neurodegeneration with brain iron accumulation disorders, characterized by extrapyramidal movement disorders and abnormal accumulation of iron in the basal ganglia. Overall, people harboring WDR45 mutations have moderate to severe DD and different types of seizures. The phenotype of adult patients is characterized by extrapyramidal…
The Use of Stable Isotope Ratio Analysis to Trace European Sea Bass (D. labrax) Originating from Different Farming Systems
2020
This study aimed to determine whether isotopic ratio mass spectrometry (IRMS) can discriminate farmed European sea bass according to different farming systems and geographic origins. Dicentrarchus labrax of commercial size from three different rearing systems (concrete tank inland, sea cages, and extensive methods in valleys or salt works) were collected at the trading period (autumn&ndash
Uniform rectifiability and ε-approximability of harmonic functions in Lp
2020
Suppose that E⊂Rn+1 is a uniformly rectifiable set of codimension 1. We show that every harmonic function is ε-approximable in Lp(Ω) for every p∈(1,∞), where Ω:=Rn+1∖E. Together with results of many authors this shows that pointwise, L∞ and Lp type ε-approximability properties of harmonic functions are all equivalent and they characterize uniform rectifiability for codimension 1 Ahlfors–David regular sets. Our results and techniques are generalizations of recent works of T. Hytönen and A. Rosén and the first author, J. M. Martell and S. Mayboroda. peerReviewed
