Water Status and Yield Response to Deficit Irrigation and Fertilization of Three Olive Oil Cultivars under the Semi-Arid Conditions of Tunisia
2019
Sustainability of olive production is possible by adopting the modern techniques of irrigation and fertilization. In Tunisia, olive trees are usually cultivated in poor soils, under semi-arid conditions characterized by water scarcity. This study investigated the effects of different water supply and fertilization on leaf water status and crop yield of three different olive oil varieties cultivated in central Tunisia, during four experimental seasons (2014&ndash
Dealing with physical barriers in bottlenose dolphin (Tursiops truncatus) distribution
2019
Abstract Worldwide, cetacean species have started to be protected, but they are still very vulnerable to accidental damage from an expanding range of human activities at sea. To properly manage these potential threats we need a detailed understanding of the seasonal distributions of these highly mobile populations. To achieve this goal, a growing effort has been underway to develop species distribution models (SDMs) that correctly describe and predict preferred species areas. However, accuracy is not always easy to achieve when physical barriers, such as islands, are present. Indeed, SDMs assume, if only implicitly, that the spatial effect is stationary, and that correlation is only depende…
Adolescent Feeding: Nutritional Risk Factors
2018
AbstractThe aim of this review is to describe adolescent nutritional requirements from a scientific, nutritional, and psychosocial point of view, emphasizing the main risks of malnutrition at this age. Currently, too many teenagers are alone at home and prepare their own meals. The influence of friends replaces parental rules. The habits of adolescents are characterized by a tendency to skip meals, especially breakfast, and, less frequently, the midday meal; to purchase carry-out meals away from home; to consume snacks, especially sweets; to eat at fast food restaurants, almost always with high-calorie content; and to eat fried foods, soft drinks, and sweets. Toxic habits, such as smoking, …
Phosphorylation of meprin β controls its cell surface abundance and subsequently diminishes ectodomain shedding
2021
Meprin β is a zinc-dependent metalloprotease exhibiting a unique cleavage specificity with strong preference for acidic amino acids at the cleavage site. Proteomic studies revealed a diverse substrate pool of meprin β including the interleukin-6 receptor (IL-6R) and the amyloid precursor protein (APP). Dysregulation of meprin β is often associated with pathological conditions such as chronic inflammation, fibrosis, or Alzheimer's disease (AD). The extracellular regulation of meprin β including interactors, sheddases, and activators has been intensively investigated while intracellular regulation has been barely addressed in the literature. This study aimed to analyze C-terminal phosphorylat…
The Metalloprotease Meprin β Is an Alternative β-Secretase of APP
2017
The membrane bound metalloprotease meprin β is important for collagen fibril assembly in connective tissue formation and for the detachment of the intestinal mucus layer for proper barrier function. Recent proteomic studies revealed dozens of putative new substrates of meprin β, including the amyloid precursor protein (APP). It was shown that APP is cleaved by meprin β in distinct ways, either at the β-secretase site resulting in increased levels of Aβ peptides, or at the N-terminus releasing 11 kDa, and 20 kDa peptide fragments. The latter event was discussed to be rather neuroprotective, whereas the ectodomain shedding of APP by meprin β reminiscent to BACE-1 is in line with the amyloid h…
Predicting soil and plant water status dynamic in olive orchards under different irrigation systems with Hydrus-2D: Model performance and scenario an…
2018
The paper analyzes the performance of Hydrus-2D model to simulate the dynamic of soil water contents and transpiration fluxes in an olive orchard in which two different irrigation systems were used in 2011 and 2012. The relationship between measured midday stem water potential, MSWP, and simulated relative transpiration (ratio between simulated actual and maximum crop transpiration), Ks, was also identified with the aim to use the model for crop water status predictions. Finally, a scenario analysis was carried out for irrigation management purposes, by considering the level of crop water stress achieved in the different phases of the vegetative growth. The results evidenced that active roo…
Al Gathafi speaks... : Afrikan yhtenäisyys ja pan-afrikanismi Muammar Gaddafin retoriikassa
2008
Tässä pro gradu -tutkielmassa tarkoituksena on selvittää, miksi ja millä tavoin aiemmin pan-arabistina tunnetun Muammar Gaddafin retoriikassa Afrikan tulee yhdentyä. Tutkimuksen kohteena on se, millaisten arvojen varaan Gaddafi omien internet-sivujen (Al Gathafi speaks…) kirjoituksissa ja puheissa luo afrikkalaisia yhdistäviä siteitä ja päämääriä. Tutkimusta täydennetään testaamalla väitettä, että puhuessaan Afrikan yhtenäisyydestä Muammar Gaddafi seuraa pan-afrikanismia ja Kwame Nkrumahin ajattelua. Testaaminen tapahtuu vertaamalla Gaddafin retoriikkaa Nkrumahin käyttämään afrikkalaisen persoonan käsitteeseen. Väitettä ei ole aiemmin empiirisesti tutkittu tieteellisillä menetelmillä. Tutki…

Tra «pentoloni per il solfato ammonico» e «un numero inverosimile di tubi»: le lettere di Carlo Emilio Gadda all’Ammonia Casale
2022
The essay analyzes the correspondence between Carlo Emilio Gadda and the "Ammonia Casale S.A." which intermittently covers a period from April 1927 to January 1940, with a long break between the autumn of 1931 and the spring of 1936. It is a decisive period of time on the public and private level. Reading the correspondence allows you to retrace an entire page of the history of Italian industry under fascism from an eccentric perspective.
L'epistolografo bugiardo. Carlo Emilio Gadda
2007
Questo libro investiga il magmatico intreccio di verità e finzione, di autobiografia e invenzione letteraria che pervade le lettere di Carlo Emilio Gadda, esaminando il rapporto di contiguità e di reciproco interscambio sussistente tra la prosa epistolare e l'opera creativa, nella convinzione che le missive possano costituire una privilegiata chiave d'accesso per penetrare nell'officina inventiva del narratore lombardo. L'analisi di Claudia Carmina segnala gli snodi cruciali e le successive trasformazioni cui, passo passo, è sottoposta l'identità travestita dell'epistolografo: dalle lettere dell'infanzia e dell'adolescenza alle epistole dal fronte, dal carteggio con Tecchi e con Betti al ma…
