Opis:
This article presents a thorough study of dislocation of superlative inferiority adjective dialogic function. The hypothesis of work stipulates that the dislocation is dialogic because the dislocated theme implies a relationship with a prior utterance by another enunciation. This relationship between two utterances is based on a comparison and makes dislocation a dialogic marker.

Stabilization energies in charged tetracene clusters : quantum chemical and microelectrostatic calculations
Autorzy:
Eilmes, Andrzej
Opis:
Theoretical calculations of the stabilization energy for an excess electron in tetracene clusters are presented. Vertical detachment energies were calculated for small clusters (up to 7 tetracene molecules) using the quantum-chemical DFT method. For larger clusters and an infinite 2D layer of tetracene molecules, the self-consistent polarization field (SCPF) method was used to calculate the polarization energy for a tetracene anion. Both DFT and SCPF results show that the charge stabilization energy increases rapidly with the cluster size and, even for clusters of less than 10 tetracene molecules, amounts to more than 50% of the bulk crystal value, which is in agreement with the conclusions of a recent experimental work.

Opis:
Colm Tóibín’s 2009 novel Brooklyn accompanies Eilis Lacey, a native of Enniscorthy, Ireland of the 1950s on a reluctant voyage across the Atlantic. Her passage reconstructs a common experience of immigration and exile to New York for the Irish working class seeking to escape the lack of prospects in small-town Ireland after the Second World War. Caught as she is between two homes-the traditional Irish culture she emerges from and the new capitalist society of America to which she emigrates-Eilis is placed in a polemical relationship to the public sphere, staked on multiple grounds of in-betweenness: she is a woman, Irish, and an exile. Belonging, for her, is posited on a complex understanding of the tensions between national and transnational identities. Eilis’s parochialism, at first, and cosmopolitanism, later on, are both decisive characteristics that become driving forces behind her social integration and marriage prospects. She is initially barred from promising job and marriage opportunities due to her naivety and lack of sophistication. As an Irish female immigrant, Eilis becomes in the course of the novel a cosmopolitan from the margins, one of the newly uprooted, and ultimately a split self.

Opis:
Bubble-particle interactions play an important role in flotation. This study examines the behaviour of bubble clusters in a turbulent flotation cell. Particularly, the bubble-particle interaction characteristics in flotation are investigated. The bubble size in a flotation column was measured using an Olympus i-SPEED 3 high-speed camera. Relationships between the circulating volume, bubble size and bubble terminal velocity were discussed. Probabilities of collision, attachment, detachment and acquisition between bubbles and particles in different circulating volumes were calculated based on the flotation kinetic theory. Using the extended Derjaguin–Landau–Verwey–Overbeek (EDLVO) theory, the relationship between the potential energy and distance in bubble-particle interaction was analysed. The results demonstrated that as the circulating volume increased, the bubble size and velocity decreased. When the circulating volume increased from 0.253 to 0.495 m3/h, the bubble diameter decreased from 511 to 462 μm, and the corresponding bubble velocity decreased from 43.1 to 37.5 mm/s. When the circulating volume remained constant as the particle size increased, probabilities of collision, attachment, detachment and acquisition increased. When the particle size remained constant as the circulating volume increased, these probabilities also increased. At a constant circulating volume as the particle size increased, the absolute value of the total potential energy between the particle and bubble increased. When the distance between the bubble and particle was 30 nm, the energy barrier appeared.

A theoretical study of small tetracene clusters : stability and charge stabilization energies
Autorzy:
Eilmes, Andrzej
Opis:
Quantum chemical calculations have been performed for small tetracene clusters. Relative stability of planar aggregates has been analyzed. Stabilization energy of small tetracene aggregates has been found to be an additive effect of interactions in pairs of neighboring molecules. Electron detachment energies from negatively charged clusters have been calculated. Results show that a large part of stabilization energy for an excess electron in tetracene lattice is reached for relatively small aggregates. These findings have been further supported by microelectrostatic calculations of the polarization energy for excess charges in tetracene crystal lattice

Opis:
This paper seeks to describe the effect of impact parameters and moisture content on kernel detachment, with the physical parameter of dissipated momentum being introduced to the process of analysing the data. Experiments were carried out on a drop-testing bed, using an accelerometer bound to corn ears to determine the impact parameters. As the impact velocity increased from 3.5 to 6.0 m s-1 at a moisture content of 18.5%, peak acceleration, the integral of acceleration and rebound velocity increased simultaneously, while impact time showed a declining trend. The mass of the detached kernels increased from 5.13 to 13.70 g per corn ear. When the moisture content of the kernels increased from 11.8 to 30.6% with an impact velocity of 5.0 m s-1, the mass of the detached kernels decreased from 12.61 to 7.56 g per corn ear. The dissipated momentum showed homologous trends with that of the detached kernel mass. Furthermore, a model of the interaction effect of impact velocity and moisture content on the mass of the detached kernel was established through full factorialtests. The methods and data may provide theoretical guidance for the design and optimization of deck plates on the corn heads and decrease the incidence of kernel detachment.

Opis:
Vitreous floaters are one of the most common complain of ophthalmological patients. The aetiology of floaters includes pathological process (vitreous haemorrhages, injuries, diabetics or uveitis) and also natural age-related changes in vitreous body. Diagnosis and treatment depends on the severity of the symptoms. Process of posterior vitreous detachment requires particularly careful monitoring, because of potential complications such as retinal tears or retinal detachment. Supplementation with anti-glycation and antioxidant substances allows to reduce complains of patients with vitreous floaters.

Opis:
The measurements of the advancing contact angle of water, glycerol, formamide, ethylene glycol, diiodomethane, α-bromonaphthalene, 1,2,3-tribromopropane on unoxidized and oxidized galena, pyrite, chalcopyrite, djurleite, bornite and covellite at the temperature equal 293 K were made. Additionally, the measurements of the force air bubble detachment from these sulfide minerals including also chalcocite in water were performed. Using the values of the obtained contact angle of water, glycerol, formamide, ethylene glycol, diiodomethane, α-bromonaphthalene, 1,2,3-tribromopropane the components and parameters of the unoxidized and oxidized sulfide minerals surface tension were calculated. For this calculation the van Oss et al. method was applied after analysis of the components and parameters of the surface tension of liquids used for contact angle measurements. Taking into account the contact angle of water on the sulfide minerals, the detachment force of air bubble from these minerals in water was determined using our equation and comparing to that of measured one. As follows from the measurements and calculations the wetting properties of sulfide minerals and the stability of mineral-air bubble depends to a larger extent on the degree of sulfide minerals oxidation than on the type of mineral.
