Thermodynamic properties of alcohols in a micellar phase. Binding constants and partial molar volumes of pentanol in sodium dodecylsulfate micelles a…

1984

Densities of the ternary system water-sodium dodecylsulfate (NaDS)-pentanol and of the binary systems butanol-octane and pentanol-octane were measured at 15, 25, and 35 °C. The apparent molar volume of pentanol in the ternary system was analyzed using a mass-action model for the alcohol distribution in micellar solutions. The partial molar volume of alcohol bound to the micelles and the ratio between the binding constant and the aggregation number of the surfactant are calculated. The partial molar volume binding constant, is discussed in terms of solubilization sites of the alcohol in the micelles whereas the binding constant is compared with that derived from the Nernstian partition const…

On monadic quantale algebras: basic properties and representation theorems

2010

Motivated by the concept of quantifier (in the sense of P. Halmos) on different algebraic structures (Boolean algebras, Heyting algebras, MV-algebras, orthomodular lattices, bounded distributive lattices) and the resulting notion of monadic algebra, the paper introduces the concept of a monadic quantale algebra, considers its properties and provides several representation theorems for the new structures.

Obstruction theory in action accessible categories

2013

Abstract We show that, in semi-abelian action accessible categories (such as the categories of groups, Lie algebras, rings, associative algebras and Poisson algebras), the obstruction to the existence of extensions is classified by the second cohomology group in the sense of Bourn. Moreover, we describe explicitly the obstruction to the existence of extensions in the case of Leibniz algebras, comparing Bourn cohomology with Loday–Pirashvili cohomology of Leibniz algebras.

Partial $\ast$-algebras of distributions

2005

The problem of multiplying elements of the conjugate dual of certain kind of commutative generalized Hilbert algebras, which are dense in the set of C ∞ -vectors of a self-adjoint operator, is considered in the framework of the so-called duality method. The multiplication is defined by identifying each distribution with a multiplication operator acting on the natural rigged Hilbert space. Certain spaces, that are an

SOME SPECTRAL PROPERTIES OF MULTIPLIERS ON SEMI-PRIME BANACH ALGEBRAS

1995

Abstract We extend to arbitrary semi-prime Banach algebras some results of spectral theory and Fredholm theory obtained in [1] and [2] for multipliers defined in commutative semi-simple Banach algebras.

GEOMETRIC EQUIVALENCE OF ALGEBRAS

2001

In this paper, we study the geometric equivalence of algebras in several varieties of algebras. We solve some of the problems formulated in [2], in particular, that of geometric equivalence for real-closed fields and finitely generated commutative groups.

Examples of improjective operators

2000

It has been an open question for some time whether improjective operators are always inessential. Here we give some examples that answer in the negative this question as well as some other related ones, posed in [2, 3, 11, 12]. The description of the examples uses a indecomposable space, constructed by Gowers and Maurey [5], and a characterization of the indecomposable Banach spaces in terms of improjective operators.

Taisnīga atlīdzība sabiedrības vajadzībām nepieciešamā nekustamā īpašuma atsavināšanas likuma kontekstā

2019

Sabiedrības vajadzībām nepieciešamā nekustamā īpašuma atsavināšanas likums paredz nekustamā īpašuma atsavināšanu sabiedrības vajadzībām labprātīgā vai piespiedu kārtā, saņemot taisnīgu atlīdzību. Pētījuma mērķis ir analizēt labprātīgas un piespiedu nekustamā īpašuma atsavināšanas sabiedrības vajadzībām procesa ietekmi uz taisnīgas atlīdzības noteikšanu nekustamā īpašuma īpašniekam. Iegūtie rezultāti liecina, ka slēdzot līgumu par labprātīgu nekustamā īpašuma atsavināšanu sabiedrības vajadzībām, nekustamā īpašuma īpašniekam ir lielākas iespējas iegūt taisnīgu atlīdzību Sabiedrības vajadzībām nepieciešamā nekustamā īpašuma atsavināšanas likuma kontekstā.

Do Overoptimistic Men Drive Creative Destruction? Evidence of Gendered Inventive Activity in Finland

2017

This study extends the analysis of the "patenting gender gap" into design rights and utility model (UMs), which are alternative methods for protecting intellectual property (IP). The analysis is descriptive and uses registry data from the Finnish patent and registration office (PRH) covering the years 1982–2013. A persistent gender gap is found for all intellectual property rights (IPRs): women are inventors and designers only in a small share of filings. The gap has narrowed over time for national patent and design right filings but not for UM filings. It is found that, in comparison to men, women are relatively less often individual inventors or designers and more often members of invento…
