Quantitative comparison of initial soil erosion processes and runoff generation in Spanish and German vineyards.
2016
The aim of this study was to enable a quantitative comparison of initial soil erosion processes in European vineyards using the same methodology and equipment. The study was conducted in four viticultural areas with different characteristics (Valencia and Málaga in Spain, Ruwer-Mosel valley and Saar-Mosel valley in Germany). Old and young vineyards, with conventional and ecological planting and management systems were compared. The same portable rainfall simulator with identical rainfall intensity (40 mm h− 1) and sampling intervals (30 min of test duration, collecting the samples at 5-min-intervals) was used over a circular test plot with 0.28 m2. The results of 83 simulations have been an…
Use of Sentinel-2 Satellite for Spatially Variable Rate Fertiliser Management in a Sicilian Vineyard
2022
Satellites can be used for producing maps of within-field crop and soil parameters and, consequentially, spatially variable rate crop input application maps. The plant vegetative vigour index (i.e., Normalised Difference Vegetation Index—NDVI) and the leaf water content index (i.e., Normalised Difference Water Index—NDWI) maps were used to study—through both time and space—the phenological phases of two plots, with Syrah and Nero d’Avola grapevine varieties, in a Sicilian vineyard farm, located in Naro (Agrigento, Sicily, Italy). The aim of this work is to produce spatially variable rate nitrogen fertiliser maps to be applied in the two vineyard plots under stu…
Erosión del suelo bajo lluvias de alta intensidad y reducida frecuencia en viñedos del este peninsular.
2014
Abstract: S imulated rainfall experiments (68.2 mm h -1 ) on plots of 1 m 2 on two vineyards in Utiel and Moixent show high soil erosion rates. These measuremen ts show that runoff rates and sediment concentration are very high due to the bare soils. Soil losses are 5.68 and 23.14 Mg ha -1 h -1 , respectively, in the study areas and Moixent and Utie l. It is confirmed that the vineyards contribute to highly erodible soils.

Distribution of chlorpromazine in a simplified blood influenced by various drugs
1973
The binding of chlorpromazine to erythrocytes and to albumin as influenced by other drugs was studied in a simplified blood (31.5±0.3% bovine erythrocytes, 4 g-% bovine serum albumin in 0.02 M phosphate buffer solution containing 0.15 M NaCl). the total concentration of chlorpromazine in the simplified blood was 10−4 M, the concentration of the displacing drugs was 10−3 M. After an incubation period of 3 h at 22° C the chlorpromazine concentration was determined in the albumin solution after centrifugation of the blood at 3000×g and in the aqueous phase after ultracentrifugation at 150000×g. Under control conditions 68.1±0.9% of chlorpromazine was bound to the erythrocytes, 28.5±0.9% was bo…
Tavoitteena vahva ja yhtenäinen kansa : historia ja kieli kansallisen identiteetin rakentamisen välineinä Pätsin aikakauden Virossa 1934-1940
2018
In this dissertation, I study national campaigns aimed at constructing Estonian national identity in 1934–1940. The campaigns were organized through the cooperation of Konstantin Päts’ authoritarian government and civil society. I focus on the folk art campaign and on the name changing campaign. The name changing campaign was the largest national project in Estonia, aiming at the Estonification of names. Initially, the campaign focused on changing individuals’ surnames and first names, but later also on changing the names of places, streets and properties. The name changing campaign had history political and language political dimensions. Through the folk art campaign, the state tried to af…
In vivo survival rate of rabbit morulae after vitrification in a medium without serum protein.
2000
The in vivo survival rate of rabbit morulae after vitrification in a mixture of dimethyl sulphoxide and ethylene glycol solution without protein supplement (WPS) was compared with two types of protein supplements: rabbit serum (RS) and bovine serum albumin (BSA). Significant dif- ferences were observed in the percentage of transferable embryos (undamaged embryos after devit- rification, 80.4 % versus 93.2 and 92.1 %, WPS, BSA and RS, respectively, P < 0.05) and live born rate (40.9 % versus 56.1 %, WPS and BSA, respectively, P < 0.05). Non-significant differences were, however, observed in the percentages of implanted embryos at 12 days post-ovulation induc- tion (56.7, 69.7 and 68.6 %), po…
Ligand-Binding Cooperativity Effects in Polymer-Protein Conjugation.
2019
We present an electron paramagnetic resonance (EPR) spectroscopic characterization of structural and dynamic effects that stem from post-translational modifications of bovine serum albumin (BSA), an established model system for polymer-protein conjugation. Beyond the typical drug delivery and biocompatibility aspect of such systems, we illustrate the causes that alter internal dynamics and therefore functionality in terms of ligand-binding to the BSA protein core. Uptake of the paramagnetic fatty acid derivative 16-doxyl stearic acid by several BSA-based squaric acid macroinitiators and polymer-protein conjugates was studied by EPR spectroscopy, aided by dynamic light scattering (DLS) and z…
Introduction : Europe, Heritage and Memory-Dissonant Encounters and Explorations
2019
The introduction to Dissonant Heritages and Memories in Contemporary Europe theoretically grounds the book’s various problematizations of heritage and identity struggles in Europe today, including the heritage policies of the EU and other intergovernmental organizations, struggles over ethnographic and historical exhibitions, activist practices, and dissonant memories. By discussing these struggles and their problematizations, the introduction connects the book to a wide range of ongoing debates across the humanities and social sciences. At the same time, it discusses how convergences and divergences within and between the volume’s chapters foster new insights regarding the concepts of diss…
Mapping evapotranspiration on vineyards: A comparison between Penman-Monteith and energy balance approaches for operational purposes
2012
Estimation of evapotranspiration (ET) in Sicilian vineyard is an emerging issue since these agricultural systems are more and more converted from rainfed to irrigated conditions, with significant impacts on the management of the scarce water resources of the region. The choice of the most appropriate methodology for assessing water use in these systems is still an issue of debating, due to the complexity of canopy and root systems and for their high spatial fragmentation. In vineyards, quality and quantity of the final product are dependent on the controlled stress conditions to be set trough irrigation. This paper reports an application of the well-known Penman-Monteith approach, applied i…
Effect of red wine soaking on the microbiological profile, total phenolic content and sensory aspects of an ovine pressed cheese
2022
The aim of this study was to produce an ovine pressed cheese with high polyphenol content. To this purpose, fresh Primosale Pecorino cheese was soaked for seven days in Nero d’Avola wine (NDW) and was indicated as experimental cheese production (EP). The final cheese was characterized for its microbiological, chemical and sensory characteristics. Specifically, cheese making was performed with pasteurized ewes’ milk and a commercial starter culture. Control cheese production (CP) did not include the soaking phase in NDW. Plate counts confirmed the dominance of the commercial starter until 109 CFU/g in both CP and EP cheeses. The soaking in NDW increased cheese total phenolic compounds (TPC) …
