Emprendimiento social en la formación profesional: el caso del País Vasco
2021
Las empresas con fines sociales o empresas de la Economía Social han sido visualizadas como una respuesta innovadora, dinámica, inclusiva y autosostenible a los principales desafíos sociales, económicos y medioambientales que enfrentan nuestras sociedades en la actualidad. Es precisamente en virtud del relevante impacto social y económico que generan las iniciativas empresariales en el ámbito del emprendimiento social que apoyar el surgimiento de emprendedores sociales se ha convertido en una necesidad, especialmente desde edades tempranas. De aquí la importancia de generar datos que permitan ya sea crear o mejorar programas ya existentes de formación de emprendedores, que contemplen entre …
Sorption and diffusion properties of volatile phenols into cork
2010
International audience; The sorption and diffusion properties of seven common volatile phenols in hydro-alcoholic medium placed in contact with natural cork were investigated to determine the influence of cork closures on the concentration of these compounds in wine. Weighted cork samples were immersed in model wine solutions containing selected concentrations of each compound and were sampled over time. Sorption coefficients ranged between 125 and 306 mg of aroma compound per kg of cork, while diffusion coefficients varied from 0.8 to 4.1 × 10−11 m2/s. Sorption isotherms of guaiacol and 4-propylguaiacol, respectively, the lowest and highest sorbed compounds of an homologous series of guaia…
Multifunctional CD4(+) T cells correlate with active Mycobacterium tuberculosis infection.
2010
Th1 CD4(+) T cells and their derived cytokines are crucial for protection against Mycobacterium tuberculosis. Using multiparametic flow cytometry, we have evaluated the distribution of seven distinct functional states (IFN-gamma/IL-2/TNF-alpha triple expressors, IFN-gamma/IL-2, IFN-gamma/TNF-alpha or TNF-alpha/IL-2 double expressors or IFN-gamma, IL-2 or TNF-alpha single expressors) of CD4(+) T cells in individuals with latent M. tuberculosis infection (LTBI) and active tuberculosis (TB). We found that triple expressors, while detectable in 85-90%TB patients, were only present in 10-15% of LTBI subjects. On the contrary, LTBI subjects had significantly higher (12- to 15-fold) proportions of…
Wideoblog - przyczyny popularności (stanowisko twórcy i odbiorcy)
2017
Punktem wyjściowym rozważań autorka uczyniła definicję pojęcia „wideoblog”. Główny nacisk położyła na sprecyzowanie i omówienie przyczyn, dla których jednostki zamieszczają autorskie materiały audiowizualne w Internecie. Poprzez poznanie motywacji twórców można wytłumaczyć, skąd bierze się tak duża popularność tego typu materiałów. Autorka zwróciła uwagę między innymi na to, jakie czynniki mogą być pomocne dla osiągnięcia sławy w Sieci. Dla lepszego zobrazowania omawianego w tekście tworu zaprezentowała parę sylwetek popularnych obecnie vlogerów oraz odwołała się do ich działalności w Sieci. Wielu youtuberów osiąga sławę nie tylko w przestrzeni Internetu, ale również poza nim. Jako że jest …
Cultivation of primmorphs from the marine sponge Suberites domuncula: morphogenetic potential of silicon and iron.
2002
Abstract Marine demosponges (phylum Porifera) are rich sources for potent bioactive compounds. With the establishment of the primmorph system from sponges, especially from Suberites domuncula , the technology to cultivate sponge cells in vitro improved considerably. This progress was possible after the elucidation that sponges are provided with characteristic metazoan cell adhesion receptors and extracellular matrix molecules which allow their cells a positioning in a complex organization pattern. This review summarizes recent data on the cultivation of sponges in aquaria and—with main emphasis—of primmorphs in vitro. It is outlined that silicon and Fe(+++) contribute substantially to the f…

Angiomyolipome der Nieren bei Morbus Bourneville-Pringle
1984
Three cases with renal angiomyolipoma in Bourneville's disease are reported. In two patients advanced renal insufficiency developed, one being treated by chronic intermittent hemodialysis. In the third patient rupture of angiomyolipoma with severe retroperitoneal bleeding occurred. In one patient, tumorous enlargement initially was diagnosed only in the right kidney and preceded angiomyolipoma of the left kidney for several years. In this patient nephrectomy was performed because malignancy was assumed before diagnosis of Bourneville's disease was established. Occasionally, histology may suggest sarcomatous changes. However, the absence of distant metastasis and the overall long survival of…
