The Paulista West region has suffered through the decades an intense process of deforestation when substituting native areas of Atlantic rainforest and Cerrado by agricultural cultivation, mainly coffee in the 20th century. This occupation process without planning and management of the soil resulted in serious erosion problems. Besides, the soil erosion promoted the reduction of agricultural production and the silting of rivers. This paper aims identify the factors of natural scope (geological, geomorphologic and pedologic characteristics) which participate in unleash of erosion process in two agricultural properties producers of coffee in order to apply mechanical techniques of recovery in erosive focuses of furrow and ravine kinds. One of the properties is at the city council of Getulina, located on the sandstones of Adamantina Formation; the other is at the city council of Vera Cruz, located on the sandstones of Marília Formation. However, taking into consideration the analysis of the natural dynamics, they are not enough to explain the complexity of the phenomena which are processed in the geographic space. It made indispensable the incorporation of socio-economic factors, such as the use and occupation process of the soil considering the society as landscape transformers. In order to better understand the importance of each one of the elements that contributes to the unleash of the studied erosions, it was collected soil samples in the areas, general descriptions and texture and morphologic analysis. Finally, it was elaborated the maps of the use and occupation of the soil and the vegetal coverage surrounding the properties studied. It was observed in the rural property of Getulina the substitution of the coffee by pasture that finds degraded. It, in addition to the cattle stomp, which changed the texture and density characteristics among the soil horizons, and the concentration of superficial water flow intensified the occurrence of ...

[EN]The methanol extracts of leaf skins and flowers of Aloe vera from the Canary Islands were analyzed for their phenolic profiles and screened for their antioxidant and antimycoplasmic activities. The use of reversed phase high performance liquid chromatography (RP-HPLC) allowed the identification of 18 phenolic constituents. Leaf skin extracts were characterized by the abundance of catechin, sinapic acid and quercitrin. Gentisic acid, epicatechin and quercitrin were the most prominent phenolic compounds of the flowers. The in vitro antioxidant activities determined by using the 1,1-diphenyl-2- picrylhydrazyl (DPPH) and ferric antioxidant reducing power (FRAP) assays revealed that both extracts exhibited antioxidant activity, being the leaf skin extract the most active fraction. The leaf skin extract was also found to be active against the microbial strains tested. Therefore, A. vera extracts from leaf skin and flowers can be considered as good natural antioxidant sources.

We assess the evidence for health benefits of three commonly consumed plant food supplements (PFS), green tea, isoflavone and aloe vera, based on published systematic reviews of randomised controlled trials (RCTs). Whilst the potential benefits of green tea have been reported in a wide range of health areas, it is only in the area of the metabolic syndrome that the number of RCTs is approaching sufficient to judge such efficacy. Isoflavone supplements are widely used, and RCTs indicate that they affect bone resorption at lower doses in postmenopausal women undergoing estrogen-related bone loss, but this is only translated to attenuation of bone loss at higher doses of isoflavones A systematic review on RCTs concluded that the effects of isoflavones

La studio dell’Anatomia umana presenta una varietà di sfaccettature, che sono alla base della reale comprensione del corpo umano; ovvero la vera anatomia non è quella rappresentata nei testi ma quella che appare durante la dissezione o nelle più sofisticate analisi di immagine. Lo scopo di questa tesi è stato quello di rivisitare alcune situazioni vascolari che possono andare incontro a variazioni e cercare di comprendere, anche con l’aiuto della bibliografia, se tali variazioni possono essere causa o epifenomeni di patologie a carico delle arterie affette dalle variazioni stesse o di territori da esse dipendenti per l’afflusso sanguigno. E’ stata condotta una analisi su preparati cadaverici in particolare in tre distretti: a) addome e tripode celiaco/mesenterica superiore; b) circolo cerebrale; d) orco aortico.

Il presente elaborato consiste in una proposta di traduzione di poesie selezionate dall’opera della poetessa Vera Pavlova, un’autrice ormai affermata in Russia ma ancora poco conosciuta all’estero, soprattutto in Italia. Proprio per questo motivo si è deciso di presentarla al lettore italiano dal punto di vista biografico e artistico. Nel primo capitolo di questo elaborato ripercorreremo infatti la sua vita, sia privata che artistica, citandone gli eventi più importanti. A questa seguirà un’introduzione alla poesia di Vera Pavlova, affrontandone sinteticamente la dichiarazione di poetica analizzando alcuni dei suoi versi. Seguirà il commento in cui verranno spiegate le principali problematiche contro le quali ci si è scontrati durante il processo traduttivo. Infine concluderemo con una riflessione che cercherà di riassumere l’essenza dell’opera di Vera Pavlova. Infine verrà la traduzione delle poesie scelte , corredate da testo originale a fronte.
