Towards a framework for assessment and management of cumulative human impacts on marine food webs
2015
Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the fo…
Stress sensitivity of stylolite morphology
2009
International audience; Stylolites are rough surfaces that form by localized stress-induced dissolution. Using a set of limestone rock samples collected at different depths from a vertical section in Cirque de Navacelles (France), we study the influence of the lithostatic stress on the stylolites morphology on the basis of a recent morphogenesis model. We measured the roughness of a series of bedding-parallel stylolites and show that their morphology exhibits a scaling invariance with two self-affine scaling regimes separated by a crossover-length (L) at the millimeter scale consistent with previous studies. The importance of the present contribution is to estimate the stylolite formation s…
¿Quién está buscando su mejor versión? Coaching y psicología deportiva en el proceso de terapeutización de (y desde) el golf
2020
This article asks about the expansion of psychological, therapeutic and self-enhancement ethos through the networks and devices that configures middle and upper-middle classes, and about the ways in which this process is singled out starting from the encounter between coaching and psychology paradigms with golf fans, in contemporary Argentina. The empirical materials that support the analysis have been ethnographically produced from the interaction with golf players and coaches.
Angļu valodas aizguvumi japāņu valodā: viltusdraugi
2019
Aizguvumi no angļu valodas sastāda lielu japāņu valodas leksikas daļu. Tiem piemīt vairākas funkcijas – tie rada izsmalcinātības sajūtu, ļauj brīvi apspriest sabiedrībā aizliegtās un nelabvēlīgās tēmas u.c. Tomēr angļu valodas aizguvumu nozīmes mēdz krasi atšķirties no angļu valodas ekvivalentiem. Bakalaura darbā ir aprakstītas japāņu valodai specifiskas aizgūšanas īpatnības, iemesli leksikas aizgūšanai no angļu valodas, kā arī semantikas maiņas procesu ietekme uz mūsdienu japāņu valodas leksiku un angļu-japāņu valodas viltusdraugu fenomens. Bakalaura darba pirmajā daļā tiek definēts termins ‘viltusdraugi’, aprakstītas vairāku leksikogrāfu klasifikācijas un attiecīgi izstrādāta angļu-japāņu…

Bcl-xL as a Modulator of Senescence and Aging
2021
Many features of aging result from the incapacity of cells to adapt to stress conditions. When cells are overwhelmed by stress, they can undergo senescence to avoid unrestricted growth of damaged cells. Recent findings have proven that cellular senescence is more than that. A specific grade of senescence promotes embryo development, tissue remodeling and wound healing. However, constant stresses and a weakening immune system can lead to senescence chronicity with aging. The accumulation of senescent cells is directly related to tissue dysfunction and age-related pathologies. Centenarians, the most aged individuals, should accumulate senescent cells and suffer from their deleterious effects,…
Consensus nomenclature for CD8(+) T cell phenotypes in cancer
2015
International audience; Whereas preclinical investigations and clinical studies have established that CD8+ T cells can profoundly affect cancer progression, the underlying mechanisms are still elusive. Challenging the prevalent view that the beneficial effect of CD8+ T cells in cancer is solely attributable to their cytotoxic activity, several reports have indicated that the ability of CD8+ T cells to promote tumor regression is dependent on their cytokine secretion profile and their ability to self-renew. Evidence has also shown that the tumor microenvironment can disarm CD8+ T cell immunity, leading to the emergence of dysfunctional CD8+ T cells. The existence of different types of CD8+ T…
La minéralité perçue dans le vin
2015
Article technique.; National audience; Beaucoup des aspects les plus fondamentaux et passionnants du vin demeurent conceptuellement insaisissables. Lorsque nous y sommes confrontés d’un point de vue sensoriel, nous pouvons avoir l’impression de bien connaître les attributs les plus abstraits du vin comme la qualité, la complexité et la minéralité, mais d’un point de vue scientifique nous savons très peu de chose sur ce que précisément ces termes signifient à la fois pour les professionnels et les consommateurs de vin. Par exemple, malgré l’intérêt actuel de la filière et des producteurs pour la perception de la minéralité dans le vin et l’utilisation de plus en plus fréquente de ce terme pa…
