Investigations of the g factors and local structure for orthorhombic Cu2+(1) site in fresh PrBa2Cu3O6+x powders

Abstract: The electron paramagnetic resonance (EPR) g factors gx, gy and gz of the orthorhombic Cu2+(1) site in fresh PrBa2Cu3O6+x powders are theoretically investigated using the perturbation formulas of the g factors for a 3d9 ion under orthorhombically elongated octahedra. The local orthorhombic distortion around the Cu2+(1) site due to the Jahn-Teller effect is described by the orthorhombic field parameters from the superposition model. The [CuO6]10- complex is found to experience an axial elongation of about 0.04 along c axis and the relative bond length variation of about 0.09 along a and b axes of the Jahn-Teller nature. The theoretical results of the g factors based on the above local structure are in reasonable agreement with the experimental data.
Theoretical studies of 63Cu Knight shifts of the normal state of YBa2Cu3O7

Condensed Matter Physics , 2011,
Abstract: The 63Cu Knight shifts and g factors for the normal state of YBa2Cu3O7 in tetragonal phase are theoretically studied in a uniform way from the high (fourth-) order perturbation formulas of these parameters for a 3d9 ion under tetragonally elongated octahedra. The calculations are quantitatively correlated with the local structure of the Cu2+(2) site in YBa2Cu3O7. The theoretical results show good agreement with the observed values, and the improvements are achieved by adopting fewer adjustable parameters as compared to the previous works. It is found that the significant anisotropy of the Knight shifts is mainly attributed to the anisotropy of the g factors due to the orbital interactions.

Abstract: this report intend to describe the proteic-energetic malnutrition associated with the intestinal parasites in a group of 149 children of both sexes between the ages of 3 and 72 months from mirassol d'oeste in the projeto polonoroeste region of mato grosso state. the data collected were: sex, age, weight and fecal samples. the weight/age data obtained was analysed using gomez's criteria. the national center for health statistic (nchs) was used as a reference model. the hoffman, pons and janer methods were used for the diagnosis of intestinal parasites. the majority of the group studied consisted of undernourished children. the majority of these were ''slightly undernourished", rather than "more undernourished" or "seriously undernourished". intestinal parasites were found in 69% of the sample studied. the most common protozoon was giardia lamblia and the ancilostomideo was the helmint most found. the x2 test did not show dependence relation between the nutritional state and the frequency of intestinal parasites.

Abstract: Foram avaliadas e selecionadas as famílias provenientes do programa de melhoramento do tomateiro da UFU, com potencial para processamento industrial e comparados seus desempenhos com os híbridos mais utilizados pelos produtores na regi o de Patos de Minas. O ensaio foi conduzido na EE Fazenda Barreiro da Unilever Bestfoods Brasil, em Patos de Minas. Utilizaram-se 30 famílias de tomateiro e os híbridos Heinz 9553, Heinz 7155N2 e Hypeel 108. As Parcelas constituíram-se de linhas duplas espa adas 0,5 m entre si, com 10 m de comprimento, irrigadas por gotejamento. O espa amento entre as linhas duplas foi de 1,3 m e a popula o de 27 mil plantas por hectare. O delineamento experimental foi de blocos ao acaso, com quatro repeti es. A semeadura foi realizada em 19/05/01. O rendimento de polpa mostrou correla es fenotípicas e genotípicas positivas com a produ o total, produ o de frutos comerciais, % de sólidos solúveis totais, colora o do suco, número de frutos maduros por planta e pH e negativa com acidez total titulável. Destacaram-se a família UFU 06 e os três híbridos comerciais.

Abstract: This study was conducted to evaluate the effect of breed types and lactation status on reproductive performance of hormonally-treated Awassi ewes. A total of 282 ewes were treated with intravaginal progestagen sponges and equine chorionic gonadotropin. Ewes were mated with fertile rams following sponge removal. Lambing rate was similar between brown- and black-faced ewes, while the percentage of multiple births, fecundity and prolificacy were greater in black-faced ewes. Lambing rate and the percentage of multiple births were similar between lactating and dry ewes. Fecundity tended to be greater in lactating ewes, while prolificacy was similar regardless of lactation status. Results of the present study indicate that black-faced Awassi ewes respond better to hormonal treatment than brown-faced ewes while the lactation status does not appear to influence the ewes’ response to hormonal treatment.

Abstract: rosemary is an exotic plant and the interest in its cultivation has been growing along the years, because it can be used for medicinal or aromatic ends, however the agricultural knowledge about the species is quite limited. the goal of this research was to evaluate the influence of the cutting height and of the interval of these cuts on the biomass production and on the yield of the rosemary essential oil. the experiment was conducted at the agronomical institute, in campinas - sp, from january 2006 through july 2007. it was organized in a completely randomized design with 8 treatments in a 2 x 4 factorial system, with two cutting heights (20 and 40 cm) and four intervals between cuts (60, 80, 100, 120 days) and three replications. characteristics such as plant height, dry mass of the aerial part, yield and quality of its essential oil were evaluated. it was observed that longer intervals among cuttings provided longer height of the plant and greater dried mass of the aerial part. the yield and the quality of the essential oil were not affected throughout the experimental period.

Abstract: To investigate the effects of Eucommia ulmoides Oliv. (EUO) on growth performance and meat quality in broilers, two hundred and forty Avian commercial broilers were randomly allotted to 4 treatments with 4 replicates, 15 birds per replicate in earlier stage (1-21 days) and 11 birds per replicate in later stage (22-49 days). Birds were fed the same basal diet supplemented with 0 (control), 0.5, 1.5 and 2.5% EUO, respectively for a period of 7 weeks ad libitum. The results on growth performance showed that dietary supplementation with 2.5% EUO increased average daily feed intake by 3.15% (p<0.01) and survival percentage by 9.21% (p<0.05). Compared with the control group, leg muscle percentage in 2.5% EUO added group was increased by 7.67% (p<0.05). The contents of soluble collagen in breast muscle were increased by 13.25% (p<0.1), 24.1% (p<0.01), 18.07% (p<0.05) and total collagen by 3.47% (p>0.05), 17.03% (p<0.05), 45.42% (p<0.01), respectively with the supplementation of different level of EUO. Birds treated with 0.5, 1.5 and 2.5% EUO also resulted in an increase of Fe in breast muscle by 14.93% (p<0.1), 82.55% (p<0.05), 68.48% (p<0.05) and Mn by 50.00% (p<0.05), 63.64% (p<0.01), 72.73% (p<0.01), respectively. In addition, supplementation with EUO in the diet increased contents of serine, glutamic acid and lysine in breast muscle. It was indicated that incorporation of moderate levels of EUO in broiler diets is beneficial to improve growth performance and meat quality.

Abstract: the objective of this work was to evaluate the behavior of two herbicides, penoxsulam and clomazone, as a function of rates and times of flooding on weed control and grain yield in rice. the trial was conducted in split-split plots and completely randomized block design, with irrigation start (19, 24 and 29 days after emergence), and two herbicides, penoxsulam (18, 36, 54 and 72 g ha-1) and clomazone (300, 400, 500 and 600 g ha-1) applied in pre-emergence of weeds and rice crop. penoxsulam, between 18 and 72 g ha-1, and clomazone, between 400 and 600 g ha-1, applied in pre-emergence in rice crop, allowed irrigation start 29 days after emergence (dae), without reductions in weed control or grain yield.
