1. Morfometria radiográfica e tomográfica em dígitos de bovinos e bubalinos / Radiographic and tomographic morphometry in digiti of the cattle and buffaloes
Radiographic and computed tomography (CT) findings may contribute to the diagnosis and prognosis of diseases based on knowledge of digits morphometric reference values. Some breeds of cattle and buffaloes still require determinations of these values for the digits. Thus, the objective with this research was to compare and correlate the condyles and phalanges

2. CLASSIFICAÇÃO ESPECTRAL E DETERMINAÇÃO DE DISTÂNCIA DE ESTRELAS EM DEZ REGIÕES HII DO HEMISFÉRIO SUL
In order to determine distances of Southern Galactic HII regions, we carried out spectroscopic and photometric observations of the stellar content of a set of these objects. We have chosen objects only visible in the South hemisphere, with no published or uncertain distances. In this work, we present spectral classification based on intermediate dispersion s

3. Morfo-anatomia e fitoquímica de Cymbopogon densiflorus (Steud.) Stapf e Cymbopogon nardus (L.) Rendle (Poaceae: Panicoideae) / Morphology, anatomy and phytochemistry of Cymbopogon densiflorus (Steud.) Stapf and Cymbopogon nardus (L.) Rendle
The genus Cymbopogon Sprengel belong to the Poaceae family and it has 40 species distributed in Tropical and Subtropical Africa, Asia and Australia, although some species went introduced in America. Many species of this genus are cultivated for the extraction of essential oil, from their leaves, with large medicinal, food and industrial importance. The speci

4. Water dynamics in level terraces. / Dinâmica da água em terraços de infiltração.
Terracing is a soil conservation practice that aims to reduce water and soil loss by interception of runoff that occurs when rainfall intensities exceed infiltration capacity. Actually, dimensions of terraces are being determined in an empirical way; however, a more detailed understanding of the physics behind the hydrological functions of terraces would all

5. Metodos de determinação do selamento superficial na irrigação por aspersão
Soil surface sealing is characterized as an organized fine particle layer with high density which can reduce the soil infiltration rate. It is caused by the impact of rainfall or irrigation water droplets. The occurrence of the soil surface sealing can result in negative effects, such as, reduction of soil water intake and soil-water holding capacity, inerca

6. Identificação do sexo atraves de medidas cranianas
The determinations of sex in human mortal remains or found heap of bones has been a great concern for thoses who work in the medical and odontological-forensic area. Experts not rarely dispose only of the cranio. The proposition of this paper was to determine the sex trough the cranial distance among the center of the external acoustic meato and eleven crani

7. Study of Adrenocorticotropic Hormone Conformation by Evaluation of Intramolecular Resonance Energy Transfer in Nε-Dansyllysine21-ACTH-(1-24)-Tetrakosipeptide
The solution conformation of ACTH was studied by intramolecular resonance energy transfer and fluorescence depolarization with the synthetic, biologically active, derivative Nε-dansyllysine21-ACTH-(1-24)-tetrakosipeptide. The Förster parameters involved in energy transfer from the donor Trp9 to the dansyl acceptor attached to the side chain of Lys21 were d

8. The carbohydrate moieties of the beta-subunit of Na+, K(+)-ATPase: their lateral motions and proximity to the cardiac glycoside site.
The beta-subunit associated with the catalytic (alpha) subunit of the mammalian Na+, K(+) -ATPase is a transmembrane glycoprotein with three extracellularly located N-glycosylation sites. Although beta appears to be essential for a functional enzyme, the role of beta and its sugars remains unknown. In these studies, steady-state and dynamic fluorescence meas

9. Genomic fluidity of Bordetella pertussis assessed by a new method for chromosomal mapping.
The genomic organization of Bordetella pertussis strains has been examined by using a new method. This method does not depend on the prior determination of a restriction map of the bacterial chromosome but is based on the ability to measure directly the distance between two genes. This is accomplished through the integration at each gene of a suicide vector

10. Shape determinations of ribosomal proteins in situ.
Ribosomes are heterogeneous for neutrons because RNA and proteins have different neutron-scattering-length densities. This heterogeneity is an obstacle to the shape determination of single ribosomal components within the ribosome. Therefore, we homogenized (matched) the neutron-scattering-length densities of RNA and proteins. 23S and 5S RNA from the large ri

11. Determination of the iron-sulfur distances in rubredoxin by x-ray absorption spectroscopy.
The high intensity x-ray flux from the synchrotron radiation at the Stanford Synchroton Radiation Project has been used to study the extended x-ray absorption fine structure (EXAFS) of the iron-sulfur protein Peptococcus aerogenes rubredoxin. Absorption measurements were made from 7080 eV, which is below the K-edge of iron, to about 650 eV above the edge and

12. Growth determinations for unattached bacteria in a contaminated aquifer.
Growth rates of unattached bacteria in groundwater contaminated with treated sewage and collected at various distances from the source of contamination were estimated by using frequency of dividing cells and tritiated-thymidine uptake and compared with growth rates obtained with unsupplemented, closed-bottle incubations. Estimates of bacterial generation tim
