1. Geological - geotechnical characterization of different lithotypes in an underground mine
Abstract A mineralogical, geological and geotechnical characterization of several rock types (phyllite, dolomite, breccia and marl) from an underground mine site aimed, among other things, to identify its mineral composition and to provide parameters to support the understanding of rock mass behavior. For this purpose, it was possible to perform laboratory a

2. Use of dentifrices to prevent erosive tooth wear: harmful or helpful?
Dental erosion is the loss of dental hard tissues caused by non-bacterial acids. Due to acid contact, the tooth surface becomes softened and more prone to abrasion from toothbrushing. Dentifrices containing different active agents may be helpful in allowing rehardening or in increasing surface resistance to further acidic or mechanical impacts. However, dent

3. pH-cycling models for in vitro evaluation of the efficacy of fluoridated dentifrices for caries control: strengths and limitations
Despite a plethora of in situ studies and clinical trials evaluating the efficacy of fluoridated dentifrices on caries control, in vitro pH cycling models are still broadly used because they mimic the dynamics of mineral loss and gain involved in caries formation. This paper critically reviews the current literature on existing pH-cycling models for the in v

4. Monensin e yeast on oil diets fed to Nellore finishing bulls / Monensina e levedura em dietas com óleo fornecidas a touros Nelores em terminação
This work had the objective of evaluate the use of monensin, yeast and the interaction of these additives on Nellore digestive metabolism and performance. It were conducted two trials. Experiment 1. It were utilized four Nellore steers with rumen and duodenum cannulas to evaluate the diet degradability, digestibility, biohydrogenation, rumen microrganisms an

5. Síntese de bisporfirinas contendo o espaçador 2,2-bipiridina: modelos na elaboração de sensores luminescentes de íons metálicos / Synthesis of bisporphyrins held together by the 2,2-bipyridine spacer: models in the elaboration of luminescent sensors for metal ions
In this work have been synthesized bisporphyrins held together by means of amide linkage at the 4,4position of 2,2-bipyridine, reacting the mono-functionalised aminophenyl-porphyrin (NH2PTriPP) and 4,4-diacid chloride bipyridine (DACBipy). A preliminary study was conducted for the establishment of the reaction conditions for the attainment of mono(nitropheny

6. Total and Cecal Digestion of Roughages in Horses. / Digestão Total e Cecal de Alimentos Volumosos em Eqüinos.
This work aimed to evaluate digestibility and degradability of nutrients, and kinetics of passage in horses fed with forages using mobile bag and in situ cecal digestion. Two digestion trials were carried out and seven forages were used, lucerne (Medicago sativa), peanut (Arachis pintoi), Desmodium ovalifolium, Stylosanthes guianensis, Cajanus cajan, Macropt

7. Degradabilidade in situ da matéria seca, matéria orgânica, fibra em detergente neutro e ácido e digestibilidade in vitro da cana-de-açúcar fresca ou ensilada e silagem de milho em diferentes ambientes ruminais / In situ dry matter, organic matter, neutral and acid detergent fiber degradability and in vitro digestibility of green chopped or ensiled sugar cane and corn silage under different ruminal conditions
The objectives of this study were to determine the in vitro dry matter (DMIVD) and organic matter (OMIVD) digestibilities and in situ degradability (ISD) of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF) of green chopped sugar cane (GCSC) or sugar cane silage (SCS), as well as corn silage (CS) under different

8. Information system for data adjustment of strengthdeformation assays of soil compaction / Sistema de informaÃÃo para ajuste dos dados de tensÃo-deformaÃÃo nos ensaios de compactaÃÃo do solo
The soil compaction is a harmful phenomenon to the agricultural sector, intensified with the current model of culture adoption though the use of machines weighed in the culture systems, where these can exert superior pressures to the soil load support capacity. With the soil compaction and compression there is a reduction of the void ratios face to the air a

9. Ensilagem e fenaÃÃo do bagaÃo de cana-de-aÃÃcar proveniente da produÃÃo de cachaÃa / Ensiling and hay-making of sugar-cane bagasse coming from rum production.
Use of sugar cane bagasse and cane tip generated in stills enables to the producer the integration of rum production with ruminant breeding. The adequate storage of bagasse can contribute towards the maintenance of its unaltered characteristics for long periods. With the objective of evaluating sugar cane bagasse (BC) coming from still rum production submitt

10. Enhanced control of Listeria monocytogenes by in situ-produced pediocin during dry fermented sausage production.
To determine whether pediocin is produced and has effective antilisterial activity during food fermentation, six sausage fermentation trials were conducted with antibiotic-resistant, pediocin-producing (Bac+) Pediococcus acidilactici PAC 1.0 (Strr Rifr) and an isogenic pediocin-negative (Bac-) derivative used as a control. Meat was inoculated (ca. 10(5) CFU/

11. Physical Activity, Weight Control, and Breast Cancer Risk and Survival: Clinical Trial Rationale and Design Considerations
Substantial observational epidemiological evidence exists that physical activity and weight control are associated with decreased risk of postmenopausal breast cancer. Uncertainty remains regarding several aspects of these associations, including the effect of possible confounding factors on these associations. We present the rationale and design for two ran

12. Rapid Identification of Staphylococcus aureus Directly from Blood Cultures by Fluorescence In Situ Hybridization with Peptide Nucleic Acid Probes
A new fluorescence in situ hybridization (FISH) method with peptide nucleic acid (PNA) probes for identification of Staphylococcus aureus directly from positive blood culture bottles that contain gram-positive cocci in clusters (GPCC) is described. The test (the S. aureus PNA FISH assay) is based on a fluorescein-labeled PNA probe that targets a species-spec
