Enhancement of Hydrolysis through the Formation of Mixed Heterometal Species: Al3+/CH3Sn3+ Mixtures

2013

ABSTRACT: The hydrolysis of mixed-metal cations (Al3+/CH3Sn3+) was studied in aqueous solutions of NaNO3, at I = 1.00 ± 0.05 mol·dm−3 and T = 298.15 K, by potentiometric technique. Several hydrolytic mixed species are formed in this mixed system, namely, Alp(CH3Sn)q(OH)r with (p, q, r) = (1, 1, 4), (1, 1, 5), (1, 1, 6), (2, 1, 4), (1, 2, 5), (1, 4, 11), (1, 3, 8), and (7, 6, 32). The stability of these species, expressed by the equilibrium: pAl3+ + qCH3Sn3+ + rOH− = Alp(CH3Sn)q(OH)r 3(p+q)−r, βpqr OH, can be modeled by the empirical relationship: log βpqr OH = −3.34 + 2.67p + 9.23(q + r). By using the equilibrium constant Xpqr relative to the formation reaction: pAl(p+q)(OH)r + q(CH3Sn)(p+q…

The paper deals with geographical names in Silesia deriving from the names of tree species. An analysis of the names derived from appellatives, allows for a reconstruction of the categorization methods of the world, anthropological conceptualization, and a popular image of reality. Name creators choose names derived from the appellatives which are for certain reasons important and valuable for them, from the existing collection of names. For example, the following names of trees and shrubs become a productive toponymic base: oak, birch, alder; they belong to the basic categorization level and are important for the rural community due to their usable and practical significance (in constructi…

Experimental study of species invasion : early population dynamics and role of disturbance in invasion success

2020

Much of our understanding of natural invasions is retrospective, based on data acquired after invaders become established. As a consequence, we know little about the characteristics of the early population growth and habitat use of the invaders during establishment. Here we report on experimental introductions of guppies into natural streams in which we conducted monthly censuses of each population. Two of the four introductions were in streams with thinned canopies, which mimics a common form of habitat disturbance. We conducted similar censuses of natural populations to characterize natural population densities and generate a null distribution against which we could test a priori hypothes…

On the occurrence of the silverstripe blaasop Lagocephalus sceleratus (Gmelin, 1789) along the Libyan coast

2012

Five individuals of Lagocephalus sceleratus were caught by trammel and gill nets off Ain Al Ghazala, Libya (approximately 32°09'N − 23°15'E) between 15 and 25 m depth in September 2010. Our findings represent the first record of this toxic species from Libya and provide further evidence of its occurrence along North African coasts.

Valorization of low value fisheries species in Sicily (Italy), by realization of functional food: a case study of high technological readiness level

2016

The growing demand for fish products of safe and local origin and the need to reduce fishing on target species, requires continuous diversification in the seafood industry, to meet the needs of consumers. One solution is represented by the use of surplus species of local fisheries, of little commercial value and often ignored by the consumer, which, if subjected to new preservation and processing methodologies, allow to create new product categories, which open up new market opportunities. In our study, we setup and applied, on some local surplus fisheries species from western Sicily, some processing technologies, aimed to valorize and extend the shelf life of fish products: the cold smokin…
