Tra uomo e donna. "Varianti sul tema" e invarianti nella scrittura

2018

Vengono individuate diverse riscritture grassiane che appaiono lungo il corso di 15 anni, ma che non si pongono lungo un continuum evolutivo. Non se ne coglie infatti un mutare evidente di usi linguistici o di istanze etico-estetiche che giustifichino i successivi e nuovi testi. Non ci sono, in quindici anni di riscrittura e nonostante i cambiamenti profondi delle sensibilità sociali sul tema del gender, attualizzazioni o integrazioni di segmenti narrativi: la Grasso reitera sempre gli stessi fotogrammi, quasi con le stesse parole e facendo riemergere sempre le stesse sensazioni. La protagonista, Enrichetta/Ninetta, non ha vita autonoma fuori dall’effetto suscitato nell’autrice bambina. Anc…

Effects of mountain grassland maturity stage and grazing management on carotenoids in sward and cow's milk

2006

Carotenoids are involved in the sensorial and nutritional values of dairy products. In grazing systems, both herbage maturity stage and grazing management may affect the amount of carotenoid ingested, thus these factors may affect carotenoid concentrations in milk. Two homogenous plots of mountain grassland (1.4 and 2.0 ha) were grazed during two cycles of growth by 6 dairy cows in mid lactation, in strip (SG) and rotational grazing (RG), respectively. We monitored the changes in carotenoid concentrations in sward and milk, measured by HPLC twice a week. Seven carotenoids were identified in the sward: violaxanthin, antheraxanthin, epilutein, lutein, zeaxanthin, ß-carotene and 13-cis ß-carot…

Risaie e Malaria

2008

In questo capitolo vengono illustrate le relazioni tra risaie e malaria tra cultura scientifica e credenze popolari. Si riportano le tappe storiche della scoperta del vettore e dell'agente patogeno, le leggi relative alla gestione delle risaie per il controllo di Anopheles e come non sempre la coltura del riso fosse l'unica causa dei miasmi e della mal' aria

Orthoptera (Insecta: Tettigonioidea, Pyrgomorphoidea, Acridoidea) of Kafa Biosphere Reserve, Bale Mountains National Park and other areas of conserva…

2016

An annotated checklist of 51 Orthoptera taxa (Tettigonioidea, Pyrgomorphoidea and Acridoidea) of Kafa Biosphere Reserve, Bale Mountains National Park and some additional sites in Ethiopia is presented. Ten species are newly recorded for the country. Four species are new to science: Peropyrrhicia attilioi n. sp., P. keffensis n. sp., P. semiensis n. sp. and Coryphosima danieli n. sp. The status of Peropyrrhicia cooperi Uvarov, 1934 and P. scotti Uvarov, 1934 is revised: both are considered valid species.

Fatty Acids Composition of Blood Cell Membranes and Peripheral Inflammation in the PREDIMED Study: A Cross-Sectional Analysis

2019

There is limited evidence from epidemiological studies for the inflammatory or anti-inflammatory properties of fatty acids in blood cell membranes. Therefore, this study examined associations between baseline (n = 282) and 1-year (n = 143) changes in the levels of fatty acids in blood cell membranes with circulating inflammatory markers in older adults at high cardiovascular risk. The data for this cross-sectional analysis was obtained from a case-control study within the PREDIMED study. Linear regression with elastic net penalty was applied to test associations between measured fatty acids and inflammatory markers. Several fatty acids were associated with interferon-&gamma

Safety and tolerability of seasonal ultra-rush, high-dose sublingual-swallow immunotherapy in allergic rhinitis to grass and tree pollens: an observa…

2009

We conducted a large observational study in 193 children and adolescents with allergic rhinitis due to grass or tree pollens to evaluate the safety and tolerability of an ultrarush high-dose sublingual immunotherapy (SLIT) regimen reaching a maintenance dose of 300 index of reactivity within 90 minutes.Children and adolescents aged 5 to 17 years with at least a 1-year medical history of allergic rhinitis with or without mild to moderate asthma due to tree pollens (birch, alder, hazel) or grass pollens (cocksfoot, meadow grass, rye grass, sweet vernal grass, timothy) were recruited. Standardized grass and tree pollen allergen extracts were used for ultrarush titration and subsequent coseason…

Massive migration from the steppe was a source for Indo-European languages in Europe

2015

We generated genome-wide data from 69 Europeans who lived between 8,000-3,000 years ago by enriching ancient DNA libraries for a target set of almost four hundred thousand polymorphisms. Enrichment of these positions decreases the sequencing required for genome-wide ancient DNA analysis by a median of around 250-fold, allowing us to study an order of magnitude more individuals than previous studies and to obtain new insights about the past. We show that the populations of western and far eastern Europe followed opposite trajectories between 8,000-5,000 years ago. At the beginning of the Neolithic period in Europe, ~8,000-7,000 years ago, closely related groups of early farmers appeared in G…

Simulated poaching affects global connectivity and efficiency in social networks of African savanna elephants-An exemplar of how human disturbance im…

2022

Selective harvest, such as poaching, impacts group-living animals directly through mortality of individuals with desirable traits, and indirectly by altering the structure of their social networks. Understanding the relationship between disturbance-induced, structural network changes and group performance in wild animals remains an outstanding problem. To address this problem, we evaluated the immediate effect of disturbance on group sociality in African savanna elephants—an example, group-living species threatened by poaching. Drawing on static association data from ten free-ranging groups, we constructed one empirically based, population-wide network and 100 virtual networks; performed a …
