1. BIODEGRADATION OF EFFLUENT CONTAMINATED WITH DIESEL OIL AND GASOLINE USING CHITOSAN AS A NATURAL COAGULANT IN A CONTINUOUS PROCESS
Abstract This study evaluated the effects of aeration (constant aeration, intermittent aeration and a lack of aeration) and hydraulic retention time (HRT) (2, 3 and 4 days) on a continuous process with cell recycling, using chitosan as a natural coagulant for the sedimentation of a C1 mixed culture. This culture was used for the biodegradation of hydrocarbon

2. Parasitos gastrintestinais de avestruzes (Struthio camelus) de diferentes idades e sua ocorrência nas épocas seca e chuvosa em um criatório no Município de Itaboraí, Estado do Rio de Janeiro. / Gastrointestinal parasites of ostriches (Struthio camelus) of different ages and their occurrence in the dry and rainy seasons in a farm in Itaboraí City, State of Rio de Janeiro.
Ostriches are susceptible to many diseases and until recently, many of them are unknown and can affect these animals when it comes to commercially breeding. In Brazil, the commercial establishment has been initiated 20 years ago, but already there are reports about the diseases that can affect these birds. The objectives of this study were identify morpholog

3. Ocorrência e sazonalidade de parasitos gastrintestinais em avestruzes (Struthio camelus) de três faixas etárias em uma criação no Município de Areal/RJ. / Occurrence and seasonality of gastrointestinal parasites of ostriches (Struthio camelus) for three ages groups in one farm in Areal/RJ.
Ostriche breeding has recently achieved commercial importance around the world. It is important to know the parasites those affect animals in commercial farms, as infections can reduce the weight gain, compromise reproductive potential and lead animals to death. Brazil has great environmental differences among its regions, depending on weather conditions and

4. Estudo da coagulação de cultura mista utilizada na biodegradação de efluente de terminais de combustíveis
O presente trabalho avaliou a capacidade de utilizar coagulantes isolados ou em combinação com um polieletrólito aniônico, que faz papel de auxiliante, na sedimentação da cultura mista C1 utilizada na biodegradação de hidrocarbonetos presentes em efluente contaminado por óleo diesel e gasolina. Os coagulantes utilizados foram sulfato de alumínio e

5. Growth of mouse megakaryocyte colonies in vitro.
Mouse bone marrow and spleen cells formed pure or mixed colonies of up to 80 megakaryocytes in agar cultures after stimulation by medium conditioned by activated mouse lymphoid cells. Megakaryocytes were identified on the basis of their morphology, polyploid mitoses and DNA content, and high cytoplasmic content of acetylcholinesterase. Megakaryocyte colony-f

6. Acid Glycohydrolases in Rat Spermatocytes, Spermatids and Spermatozoa: Enzyme Activities, Biosynthesis and Immunolocalization
Mammalian sperm acrosome contains several glycohydrolases thought to aid in the dispersion and digestion of vestments surrounding the egg. In this study, we have used multiple approaches to examine the origin of acrosome-associated glycohdyrdolases. Mixed spermatogenic cells, prepared from rat testis, were separated by unit gravity sedimentation. The puri

7. High-molecular-mass multicatalytic proteinase complexes produced by the nitrogen-fixing actinomycete Frankia strain BR.
A major-high-molecular mass proteinase and seven latent minor proteinases were found in cell extracts and in concentrates of culture medium from Frankia sp. strain BR after nondenaturing electrophoresis in mixed gelatin-polyacrylamide gels. All of these complexes showed multicatalytic properties. Their molecular masses and their sedimentation coefficients va
