Evidence for the Existence of an Effective Interfacial Tension between Miscible Fluids: Isobutyric Acid-Water and 1-Butanol-Water in a Spinning-Drop …

2006

We report definitive evidence for an effective interfacial tension between two types of miscible fluids using spinning-drop tensiometry (SDT). Isobutyric acid (IBA) and water have an upper critical solution temperature (UCST) of 26.3 degrees C. We created a drop of the IBA-rich phase in the water-rich phase below the UCST and then increased the temperature above it. Long after the fluids have reached thermal equilibrium, the drop persists. By plotting the inverse of the drop radius cubed (r(-)(3)) vs the rotation rate squared (omega(2)), we confirmed that an interfacial tension exists and estimated its value. The transition between the miscible fluids remained sharp instead of becoming more…

Il reliquiario a sarcofago di Santa Ninfa a Palermo

2022

In full affirmation of the themes of the Counter-Reformation, the city of Palermo pays homage to one of its Patronesses with the creation of a monumental silver urn. Through the analysis of documentary sources and the necessary formal and stylistic surveys, the history of the precious sacred goldsmith's work is reconstructed

L’écriture et le graphisme à l’ère de la linguistique psychologique

2016

This study deals with the conception of “writing” within the German humanities during the « psychological turn » of the last half of the XIXth - the beginning of the XXth centuries. The focal point is “graphism” and “writing” understood as “expressive movements” (Ausdrucksbewegungen), this notion being bound to the concept of “verbal gesture” within the trend of “psychological linguistics” (1850-1930). Inspired initially by the morphological and physiognomonic tradition (J. Lavater, J. W. Goethe, J. Engel, C. Carus, Th. Piderit), this conception considers language as a particular kind of “expressive movements”. This vision comes back to the German psychology of consciousness elaborated by J…

Accounting for service quality to customers in the efficiency of water companies: evidence from England and Wales

2015

This paper investigates the role of service quality to customers in the efficiency assessment of water companies in England and Wales. To achieve this, data envelopment analysis techniques are employed to compute the technical efficiency of the water companies following two approaches: (i) traditional assessment based on quantity variables (without the inclusion of service quality variables) and (ii) alternative assessment considering quantity and service quality variables as undesirable outputs. The analysis covers 22 water and sewerage companies and water only companies providing drinking water services. The results indicate that the traditional efficiency assessment reveals a high level …

Essential Oils as Nematicides in Plant Protection-A Review

2023

By 2030, the European Commission intends to halve chemical pesticide use and its consequent risks. Among pesticides, nematicides are chemical agents used to control parasitic roundworms in agriculture. In recent decades, researchers have been looking for more sustainable alternatives with the same effectiveness but a limited impact on the environment and ecosystems. Essential oils (EOs) are similar bioactive compounds and potential substitutes. Different studies on the use of EOs as nematicides are available in the Scopus database in the scientific literature. These works show a wider exploration of EO effects in vitro than in vivo on different nematode populations. Nevertheless, a review o…

Microbiological and physicochemical profile of sugar added ewe’s Ricotta during storage

2022

The microbiological and physicochemical traits of fresh ewe’s Ricotta made with (40% w/w) and without sucrose were investigated. Sugar added Ricotta (SAR) andcontrol Ricotta (CTR) were packaged and stored at 4°C for 90 d. Salmonella spp., Listeria monocytogenes,Escherichia coli, coagulase positive staphylococci, Enterobacteriaceae, total coliforms, Pseudomonas, yeasts, moulds and clostridia were undetectable during the entire monitoring. Total mesophilic and psychrotrophic microorganisms and mesophilic cocci lactic acid bacteria increased over time,but their development was limited in SAR production. The acidificationwas observed only for CTR. Water activity was consistently low(0.897 on av…

Effects of grazing Trifolium subterraneum and Lolium multiflorum in various proportions on forage intake and milk production of dairy ewes

2011

The aim of this research was to evaluate the effects of grazing Trifolium subterraneum (T) and Lolium multiflorum (L), as pure or associated crops, on forage intake and milk yield and composition in Comisana ewes. The four following fenced subplots, each of 2500 m2, were used for grazing: T, 100% of surface; L, 100% of surface; TL, T and L on 66.6 and 33.3 % of surface; LT, T and L on 33.3 and 66.6% of surface, respectively. Each subplot was divided into two parcels in order to have two replicates. Forty ewes were divided into eight homogeneous groups, with regard to milk yield, days in milk and live weight. In spring for 70 days, each group grazed daily for 8 h one of the fenced parcels. M…

Effect of the inclusion of lemon citrus pulp in the diet of Valle del Belice lactating ewes. Milk production and composition.

2015

Lemon citrus pulp residues from the citrus juice industry; it belongs to the citrus by-product that are more extensively used for livestock feeding. Furthermore, citrus pulp is a source of flavonoids such as hesperidin and naringin, which have antioxidant properties. This study aimed to investigate the effect of fresh lemon citrus pulp (LP) as natural antioxidant, on feeding behavior, milk yield and milk quality of Valle del Belice lactating ewes in the hot summer season in Sicily. A total of 15 second lambing ewes were individually allocated in 3¥3 m box and fed with 3 diets in a 3 ¥ 3 Latin square design, with 3 phases composed of 21 days. The diets were: LP0, mixed hay ad libitum plus 60…
