A Nonrelativistic Chiral Soliton in One Dimension

I analyze the one-dimensional, cubic Schr\"odinger equation, with nonlinearity constructed from the current density, rather than, as is usual, from the charge density. A soliton solution is found, where the soliton moves only in one direction. Relation to higher-dimensional Chern--Simons theory is indicated. The theory is quantized and results for the two-body quantum problem agree at weak coupling with those coming from a semiclassical quantization of the soliton.Comment: 11 pages, Latex2

The BPS Domain Wall Solutions in Self-Dual Chern-Simons-Higgs Systems

We study domain wall solitons in the relativistic self-dual Chern-Simons Higgs systems by the dimensional reduction method to two dimensional spacetime. The Bogomolny bound on the energy is given by two conserved quantities in a similar way that the energy bound for BPS dyons is set in some Yang-Mills-Higgs systems in four dimensions. We find the explicit soliton configurations which saturate the energy bound and their nonrelativistic counter parts. We also discuss the underlying N=2 supersymmetry.Comment: 16 pages, LaTeX, no figure, a minor change in acknowledgment

Influência do óleo de linhaça sobre o desempenho e a qualidade dos ovos de poedeiras semipesadas Influence of linseed oil on performance and egg quality of semi-heavy laying hens

O experimento foi conduzido para avaliar a influência da adição de óleo de linhaça em substituição ao óleo de soja em rações para poedeiras semipesadas sobre o desempenho e a qualidade interna e externa dos ovos. Utilizaram-se 192 poedeiras da linhagem Bovans Godline com 29 semanas de idade, distribuídas em seis tratamentos, que consistiram de uma dieta controle (sem óleo vegetal) e de cinco dietas contendo 0,0; 0,5; 1,0; 1,5 e 2,0% de óleo de linhaça em substituição, respectivamente, a 100, 75, 50, 25 ou 0% do óleo de soja. Avaliaram-se a produção (PROD), o peso (PO) e a massa de ovo (MO), as conversões por massa (CMO) e por dúzia de ovos (CDZ), os pesos e as porcentagens de albúmen, gema e casca, a gravidade específica, os teores de matéria seca, cinzas e proteína do albúmen e da gema e o teor de colesterol e a coloração da gema. A produção, o peso do ovo, a massa de ovo e as conversões por massa e por dúzia de ovos, bem como a qualidade interna e externa dos ovos, não foram influenciados pelos níveis de óleo de linhaça na ração. Do mesmo modo, não houve efeito da inclusão de óleo de linhaça sobre a composição química dos ovos e somente a coloração da gema foi intensificada quando utilizados níveis acima de 1% de óleo de linhaça na dieta. A adição de até 2% de óleo de linhaça na ração não altera o desempenho de poedeiras semipesadas nem a qualidade interna e externa e o teor de colesterol dos ovos.<br>This experiment was carried out to evaluate the influence of the linseed oil addition in replacement of soybean oil in laying hens diets on performance and internal and external egg quality. A total of 192 laying hens Bovans Godline line with 29 week-old, were distributed to six treatments, that consisted of a control diet (without vegetal oil) and of five diets containing 2% of linseed oil in replacement of 0, 25, 50, 75 and 100% of soybean oil, generating levels of 0.0, 0.5, 1.0, 1.5 and 2.0 % of linseed oil in the diets. The evaluated parameters were: production (PROD), egg weight (EW) and mass (EM), feed:egg mass ratio (FEM) and feed:egg dozen ratio (FED), albumen, yolk and shell weights and percentages, specific gravity, albumen and yolk dry matter, ashes and protein, yolk cholesterol and coloration. The production , EW, EM, FEM and FED, as for internal and external egg quality, were not influenced by the linseed oil levels in the diet. Likewise, no effect was observed on egg chemical composition and only yolk coloration was intensified with the levels above 1% of linseed oil in the diet. The addition of up to 2% f linseed oil on diet did not alter the performance on semi-heavy laying hens, and the internal and external egg quality and cholesterol
