Magnetic properties of smooth terminating dipole bands in 110,112Te
2006
Three strongly coupled sequences have been established in Te-110,Te-112 up to high spins. They are interpreted in terms of deformed structures built on proton 1-particle-1-hole excitations that reach termination at I similar to 40h. This is the first observation of smooth terminating dipole structures in this mass region. Lifetime measurements have allowed the extraction of experimental B(M 1; 1 -> I - 1) and B(E2; I -> I - 2) reduced transition rates for one of the dipole bands in Te-110. The results support the deformed interpretation. (c) 2006 Elsevier B.V. All rights reserved.
Litchi (Litchi chinensis Sonn.): a comprehensive review of phytochemistry, medicinal properties, and product development
2021
Since ancient times, litchi has been well recognized as a functional food for the management of various ailments. Many bioactives, including flavanoids, anthocyanins, phenolics, sesquiterpenes, triterpenes, and lignans, have been identified from litchi with a myriad of biological properties both in vitro and in vivo. In spite of the extensive research progress, systemic reviews regarding the bioactives of litchi are rather scarce. Therefore, it is crucial to comprehensively analyze the pharmacological activities and the structure-activity relationships of the abundant bioactives of litchi. Besides, more and more studies have focused on litchi preservation and development of its by-products,…
A Review of the Phytochemistry, Traditional Uses and Biological Activities of the Essential Oils of Genus Teucrium
2020
AbstractThe genus Teucrium is a large and polymorphic genus of the Lamiaceae family distributed in mild climate zones, particularly in the Mediterranean basin and Central Asia. Studies of nonvolatile constituents of Teucrium species showed that they are a rich source of neo-clerodane diterpenoids, considered as chemotaxonomic markers of the genus. In addition to the nonvolatile metabolites, there has been a large interest in the essential oils of this genus. In this review, a complete survey of the chemical composition and biological properties of the essential oils isolated from Teucrium taxa is provided. In traditional medicine, since ancient times, species of this genus have been widely …
Towards crossing the borders in foreign language teacher training: A report on a pilot phase of the Tandem Learning for Teacher Training project
2018
The aim of the paper is to present the results of a pilot project for foreign language (FL) teacher education, in which trainee teachers’ knowledge and awareness of intercultural and cross-educational similarities and differences between two cooperating institutions from socio-culturally and linguistically distant countries – Israel and Poland – are elicited. The data collected serves as a springboard for designing an international project for FL trainee teachers to be implemented as a part of a teacher training course. In the project the trainee teachers coming from geographically, culturally and linguistically detached backgrounds, Israeli and Polish, are to participate in tandem learning…
Available Defences for Defendants in the Provisional Measures in Europe: Between Theory and Practice
2014
The EU Enforcement Directive provides a set of provisional measures to be applied by a request of a right-holder of a particular object of intellectual property. Simultaneously, the EU Enforcement Directive envisages a set of defences for an alleged infringer in order to safeguard the balance of parties. This article discusses available defences for an alleged infringer in provisional measures as provided by the EU Member States when norms of the EU Enforcement Directive are transposed in conjuncture with the available court practice. Specifically, the present article focuses not only on the threshold of evidence to be presented by a plaintiff for application of provisional measures but als…
Available Defences in Provisional measures: Between the Enforcement Directive and National law
2015
AbstractThe EU Enforcement Directive provides a set of provisional measures to be applied upon request from a right-holder of a particular object of intellectual property. Simultaneously, the EU Enforcement Directive envisages a set of defences for an alleged infringer (defendant) in order to safeguard the balance of the parties. This article discusses available defences for an alleged infringer in the provisional measures as provided by the EU Member States when the norms of the EU Enforcement Directive are transposed. Specifically, the present article not only focuses on the threshold of evidence to be presented by a plaintiff for the application of provisional measures, but also in regar…
γ‐Agregation operators and some aspects of generalized aggregation problem
2010
We explore questions related to the aggregation operators and aggregation of fuzzy sets. No preliminary knowledge of the aggregation operators theory and of the fuzzy sets theory are required, because all necessary information is given in Section 2. Later we introduce a new class of γ‐aggregation operators, which “ignore” arguments less than γ. Due to this property γ‐aggregation operators simplify the aggregation process and extend the area of possible applications. The second part of the paper is devoted to the generalized aggregation problem. We use the definition of generalized aggregation operator, introduced by A. Takaci in [7], and study the pointwise extension of a γ‐agop. First publ…
A pointwise selection principle for metric semigroup valued functions
2008
Abstract Let ∅ ≠ T ⊂ R , ( X , d , + ) be an additive commutative semigroup with metric d satisfying d ( x + z , y + z ) = d ( x , y ) for all x , y , z ∈ X , and X T the set of all functions from T into X . If n ∈ N and f , g ∈ X T , we set ν ( n , f , g , T ) = sup ∑ i = 1 n d ( f ( t i ) + g ( s i ) , g ( t i ) + f ( s i ) ) , where the supremum is taken over all numbers s 1 , … , s n , t 1 , … , t n from T such that s 1 ⩽ t 1 ⩽ s 2 ⩽ t 2 ⩽ ⋯ ⩽ s n ⩽ t n . We prove the following pointwise selection theorem: If a sequence of functions { f j } j ∈ N ⊂ X T is such that the closure in X of the set { f j ( t ) } j ∈ N is compact for each t ∈ T , and lim n → ∞ ( 1 n lim N → ∞ sup j , k ⩾ N , j…
Estimation of vapor pressures, solubilities and Henry's law constants of selected persistent organic pollutants as functions of temperature
1999
Abstract An internally consistent set of temperature dependent physical-chemical property data was derived for 73 persistent organic pollutants, including polychlorinated biphenyls, diphenylethers, dibenzo-p-dioxins, and dibenzofurans, organochlorinated pesticides and polycyclic aromatic hydrocarbons. Measured data reported in the literature were expanded by different estimation and regression methods. Temperature dependent vapor pressures were estimated from relative gas chromatographic retention times and by a modified Watson equation. Temperature dependent water solubilities were estimated by equations based on mobile order theory modified from Ruelle and Kesselring. The temperature depe…
Overcoming the PEG-addiction: well-defined alternatives to PEG from structure-property relationships to better defined therapeutics
2011
Synthetic methods in polymer chemistry have evolved tremendously during the last decade. Nowadays more and more attention is devoted to the application of those tools in the development of the next generation of nanomedicines. Nevertheless, poly(ethylene glycol) (PEG) remains the most frequently used polymer for biomedical applications. In this review, we try to summarize recent efforts and developments in controlled polymerisation techniques that may allow alternatives to PEG based systems and can be used to improve the properties of future polymer therapeutics.
