  1. Procedure for reducing hydrogen ion concentration in acidic anion eluate

    International Nuclear Information System (INIS)

    A procedure is suggested for reducing the concentration of hydrogen ions in the acidic anionic eluate formed during the separation of uranium. The procedure involves anex elution, precipitation, filtration, precipitate rinsing, and anex rinsing. The procedure is included in the uranium elution process and requires at least one ion exchanger column and at least one tank in the continuous or discontinuous mode. Sparing the neutralizing agent by reducing the hydrogen ion concentration in the acidic anionic eluate is a major asset of this procedure. (Z.S.). 1 fig

  3. Excretion analysis of a case of old internal contamination with 241Am

    International Nuclear Information System (INIS)

    Two radiochemical methods were used in parallel to determine 241Am in the urine and feces of a person who had been internally contaminated with that radionuclide 25 years before. Both methods used feces and urine mineralizations. The first method comprised coprecipitation of Am together with alkaline earth metals by using bismuth phosphate, single separation on a catex, double separation on an anex, and extraction of Am into TTA in benzene. The other method consists of double coprecipitation of Am, viz., with calcium oxalate and with Fe(OH)3, followed by double separation on an anex and a single separation on a catex. In both methods, 243Am served as the recovery indicator and in the preparation of electrodeposition samples. The samples were measured by alpha spectrometry using PIPS detectors

    Introduction: Apoptosis or programmed cell death is an active, energy-dependent mechanism for elimination of cells that have been injured, infected, or immunologically recognized as harmful or superfluous. Apoptosis may be used in diagnosis of malignant tumors as it often occurs in hypoxic zones adjoining areas of necrosis, and it is endpoint of most forms of anticancer therapy. The N-terminal sequence of Annexin V, consisting of 13 amino acids (Anx13), is considered a useful marker in this context because of interaction with other molecules such as phosphatidyl-serine, the compound expressed on the surface of the apoptotic cells. Aim: The scope of this study was the labeling of Anx13 fragment with the derivatization of it for nitride and tricarbonyl technetium approach, and their biological evaluation. Methods: For nitride technetium labeling, a readily-available lyophilized kit (Schering CIS Bio International) was used. Na{sup 99m}TcO{sub 4} was added to this kit as well absolute ethanol. The reaction vial was left standing at room temperature for a period of 30 min. Then, a 0.9 mM aqueous solution of Cys-Anx13 and diphosphine (PNP6), was added. This reaction was carried out for one hour at 100 deg C. Preparation of the {sup 99m}Tccarbonyl consisted in flushing the mixture of 4.4 mg of sodium carbonate, 5.5 mg of sodium borohydride and 20 mg of sodium-potassium tartrate tetrahydrate with CO gas during 30 min. Pertechnetate was added and the vial was heated for 35 min at 75 deg C. The reaction was stopped in ice bath, and pH was adjusted to 7. Then 100 {mu}L of the precursor was added to 1.1 mM (50 {mu}g) of His-Anx13 and heated at 75 deg C for 60 min. The reaction was stopped in ice bath. Radiochemical analysis of both complexes {sup 99m}TcN(PNP6)-Cys-Anex13 and {sup 99m}Tc(CO)3-His-Anx13 was performed by thin layer chromatography as well as by HPLC. Biodistribution studies were carried out in healthy animals, 4 hours post injection of the {sup 99m

    Full Text Available O manejo sustentado de agroecossistemas passa pelo planejamento de uso dos mesmos, para o que necessita serem avaliados os recursos naturais e as condições sociais, culturais e econômicas dos habitantes. Técnicas de geoprocessamento e sensoriamento remoto, que permitem avaliar os recursos de grandes áreas e anexá-los a bancos de dados georreferenciados, foram utilizados para caracterizar o meio físico e planejar o uso da fazenda El Pantanoso, Departamento de Cerro Largo, Uruguai. Dados topográficos, planialtimétricos, de solo e uso atual, foram usados para gerar os planos de informação: mapa base, modelo numérico do terreno, declividade, solos, aptidão de uso agrícola dos solos, uso atual, zoneamento ambiental e conflitos de uso. A pesquisa mostra que a região apresenta Planossolos, Argissolos, Chernossolos, Vertissolos, Organossolos, Neossolos e Gleissolos e que os mesmos apresentam ampla faixa de aptidão de uso, o que facilita seu zoneamento ambiental. Considerando-se que a tradicional pecuária desenvolvida nas áreas de topografia ondulada e arroz nas várzeas, constitui o uso adequado dos solos, então lavouras de arroz encontradas ao longo dos sistemas de drenagem, onde deveria ser mantida a vegetação ciliar natural, constitui o principal conflito de uso relacionado ao zoneamento ambiental da região. O geoprocessamento e sensoriamento remoto mostraram-se eficientes no planejamento de uso da Fazenda Pantanoso.The sustainable management of agro-ecological systems go through the planning of their use. To reach this objective, the natural resources as well as the social, cultural and economical conditions of the inhabitants of the study area need to be evaluated.
