13. PARÂMETROS DE IRRIGAÇÃO PARA O FEIJOEIRO EM DIFERENTES SOLOS E ÉPOCAS DE SEMEADURA NA REGIÃO CENTRAL DO RIO GRANDE DO SUL / IRRIGATION PARAMETERS FOR COMMON BEAN IN DIFFERENT SOILS AND SOWING DATES IN THE CENTRAL REGION OF RIO GRANDE DO SUL
Common bean is produced in the entire territory of Brazil and it is the staple food of many Brazilians. In spite of being cultivated in a variety of meteorological conditions, common bean is a plant sensitive to environmental stresses, mainly water stress. To appropriately provide the plant with water, it is necessary to study the climate of the region and t

14. Preparação e padronização de metodologia de marcação in vitroe estudo de biodistribuição do octreotídeo-[Tyr3]-HYNIC/EDDA/TRICINA-[99mTc / PREPARATION AND STANDARDIZATION OF AN IN VITRO LABELING METHODOLOGY AND STUDY OF [99mTc]-EDDA/TRICINE/HYNIC-[Tyr3]-OCTREOTIDE BIODISTRIBUTION
Somatostatine receptors are widely expressed by several tumors, especially of the neuroendocrine origin. In vivo images of these tumors using radiolabeled somatostatine analogues became a useful clinical tool in oncology. The radiopharmaceutical currently applied is [111In-DTPA-Phe1-D]-octreotide. However, the use of indium-111 (111In) is limited by the prod

15. Análise estratigráfica de alta resolução do intervalo praguiano-neoemsiano (Formação Ponta Grossa), na borda leste da Bacia do Paraná, com base em dados geoquímicos e sedimentológicos / High resolution stratigraphic analysis of praguian-neoemsian interval (Ponta Grossa Formation), at eastern edge of Parana Basin, with base on geochemical and sedimentologic datas
This work is the result of detailed stratigraphic analysis on the sedimentary record of Praguian?Emsian later interval, established on core samples of four wells in the Paleozoic outcrop section, eastern edge of Paran? Basin. Data set was obtained by means of sedimentology, gamma spectrometry and organic geochemistry (total organic carbon and pirolysis Rock-

16. "Tomografia computadorizada, atenuação de raios gama e análise micromorfológica na avaliação de alterações na estrutura e retenção de água pelo solo" / Computed tomography, gamma-ray attenuation, and micromorphologic analysis to evaluate changes on soil structure and water retention
Soil structure is related to the arrangement of soil particles, aggregates, and pores, which makes part of this porous media. The influence of structure on soil physical phenomena ranges from macro to microscope scale. Structure changes in microscope scale are important because affect the soil particle arrangement and, consequently, the pores distribution. S

17. Descontaminação de embalagens descartadas de clorpirifós utilizando o processo de oxidação avançada por radiação ionizante / Decontamination of used pesticide packaging using advanced oxidation process by ionizing radiation
The discharge of empty plastic packaging of pesticides can be an environmental concern causing problems to human health, animals and plants if done without inspection and monitoring. Among the commercial pesticides, chlorpyrifos has significant importance because of its wide distribution and extensive use and persistence. The hydroxil OH atack is the most ef

18. The use of gamma ray computed tomography to investigate soil compaction due to core sampling devices
Compaction processes can influence soil physical properties such as soil density, porosity, pore size distribution, and processes like soil water and nutrient movements, root system distribution, and others. Soil porosity modification has important consequences like alterations in results of soil water retention curves. These alterations may cause difference

19. Estudo do efeito de processos de esterilização sobre propriedades de interesse para compostos de PVC plastificado utilizados na confecção de bolsas para coleta e transfusão de sangue
The study of the effect of thermal sterilization and gamma irradiation on compositions of PVC resin with di-2-ethylhexil phatalate (DOP), tri-2-ethylhexil trimellitate (TOTM) and tributyl acetyl-citrate (ATBC) was conducted by measuring changes in mechanical, chemical, and permeability chatacteristics. The PVC used was obtained in powder form, and was synthe

20. Experimental determination of radiation dose distribution in an heterogeneous medium, irradiated with clinical beams of x and gamma rays / Determinação experimental da distribuição de dose de radiação em meio heterôgenio, irradiado por raios-x e gama radioterápicos
An experimental study of the perturbation caused by a cylindrical inhomogeneity of aluminium on dose distribution in a water phantom, irradiated by high energy photons used in radiation therapy, was performed, employing radiographic film as dosimeter. With these materials we intended to simulate the interface between bone and muscular tissue. The film was pl

21. Medida de fração de vazio superficial num escoamento bifoisico gas-liquido pelatecnica de atenuação de raios gama
The evaluation of void fraction in gas liquid two-phase flow is essential for a through understanding of the fluid hydrodynamics associated tothe multiphase flow. Many void fraction measurement techniques have been developed, and those already known have been improved, so that the goal of measuring them faster and more acurately may be attained. The present

22. In situ identification of bacteria in drinking water and adjoining biofilms by hybridization with 16S and 23S rRNA-directed fluorescent oligonucleotide probes.
Free-water-phase and surface-associated microorganisms from drinking water were detected and roughly identified by hybridization with fluorescence-labeled oligonucleotide probes complementary to regions of 16S and 23S rRNA characteristic for the domains Bacteria, Archaea, and Eucarya and the beta and gamma subclasses of Proteobacteria. Samples of glass-attac

23. Membrane attack complex of complement: distribution of subunits between the hydrocarbon phase of target membranes and water.
Membrane destruction by complement is effected by the membrane attack complex (MAC) which is the dimer of a fusion product of the complement proteins C5b, C6, C7, C8, and C9. Phospholipid bilayer vesicles were used as target membranes for the MAC and its intermediate complexes. The subunits of these membrane-bound complexes were explored as to their relative

24. Changes in the Microflora of Haddock Fillets and Shucked Soft-Shelled Clams After Irradiation with Co60 Gamma Rays and Storage at 0 C and 6 C
Frequency distribution patterns of aerobic-facultative microflora, obtained by random selection of macrocolonies from samples of haddock fillets and shucked soft-shelled clams before and after treatment with doses of from 50,000 to 800,000 rad of Co60 gamma rays, are presented, with analyses and interpretation. The data showed that a decided change occurred
