1. OPTIMIZATION OF HYDROELECTRIC INVENTORY STUDIES / OTIMIZAÇÃO DE ESTUDOS DE INVENTÁRIO HIDROELÉTRICOS
O desenvolvimento de estudos de inventário para Pequenas Centrais Hidroelétricas ¿ PCHs ¿ é uma atividade custosa e demorada. A motivação desta dissertação é, de forma rápida e econômica, verificar a real viabilidade destes projetos. Um modelo computacional foi criado para automatizar estudos de inventário, identificando o potencial de geração

2. Maxilofacial trauma in pediatric and adolescent patients : an epidemiological analysis / Traumatismos faciais em pacientes pediatricos e adolescentes : analise epidemiologica
We performed a retrospective study to analyse the different characteristics of such fractures in the pediatric population of Piracicaba Region, Sao Paulo, Brazil. We reviewed the clinical records of 2986 patients. A total of 757 patients under 18 years were treated by the Oral and Maxillofacial Surgery Division of Piracicaba Dental School between 1999 and 20

3. A utilização de tecnologias digitais de geoprocessamento na identificação de unidades de paisagem na bacia hidrográfica do rio Iguaçu-Sarapuí (RJ) / The use of gis technology in identification of landscape units in the Iguaçu river
The Iguaçu River Falls is part of the river basin of Guanabara Bay. Its drainage area, with about 726 km2, corresponds to approximately 20% of the total area of contribution to the Bay, the order of 4600 km2. The municipalities covered by the Iguaçu River basin are: Nova Iguaçu, Duque de Caxias, Belford Roxo, São João de Meriti, Nilópolis, mosque and a

4. The sound circuit : radio FM and music production in Campinas-SP / O circuito sonoro : radiodifusão FM e produção fonografica em Campinas-SP
This research examines the dynamic socio-territorial in the city today. For this reason, we are looking forward to contribute to the understanding of the formation and the thickness of the circuits of radio FM and the music production in Campinas. The circuit FM in Campinas falls in the field of cultural industry since de decade of 1970, and has been expandi

5. Estudo epidemiologico das fraturas do complexo zigomatico-orbitario e arco zigomatico tratadas pela Area de Cirurgia e Traumatologia Buco-Maxilo-Facias da Faculdade de Odontologia de Piracicaba - Unicamp
The purpose of this study was review, during a five-year period, the zygomatic-orbital complex and zygomatic arch fractures treated by the Division of Oral and Maxillofacial Surgery of Piracicaba Dental School ? Unicamp. The age and sex distribution, anatomical types of fractures, associated maxillofacial and nonmaxillofacial trauma, causes of injuries were

6. Lack of S-Adenosylmethionine Results in a Cell Division Defect in Escherichia coli
The enzyme S-adenosylmethionine (SAM) synthetase, the Escherichia coli metK gene product, produces SAM, the cell’s major methyl donor. We show here that SAM synthetase activity is induced by leucine and repressed by Lrp, the leucine-responsive regulatory protein. When SAM synthetase activity falls below a certain critical threshold, the cells produce long

7. An archaebacterial homologue of the essential eubacterial cell division protein FtsZ.
Life falls into three fundamental domains--Archaea, Bacteria, and Eucarya (formerly archaebacteria, eubacteria, and eukaryotes,. respectively). Though Archaea lack nuclei and share many morphological features with Bacteria, molecular analyses, principally of the transcription and translation machineries, have suggested that Archaea are more related to Eucary

8. Changes in the total number of neuroglia, mitotic cells and necrotic cells in the anterior limb of the mouse anterior commissure following hypoxic stress.
The effects of hypoxic stress (390 mmHg) on the total number of glia, cell division, and cell death in the anterior limb of the anterior commissure were studied. There was a significant (P less than 0-01) fall in the total number of glia following exposure to hypoxia at 390 mmHg for two days. No significant change was observed in the total number of glia bet

9. Phylogenetic analysis of dissimilatory Fe(III)-reducing bacteria.
Evolutionary relationships among strictly anaerobic dissimilatory Fe(III)-reducing bacteria obtained from a diversity of sedimentary environments were examined by phylogenetic analysis of 16S rRNA gene sequences. Members of the genera Geobacter, Desulfuromonas, Pelobacter, and Desulfuromusa formed a monophyletic group within the delta subdivision of the clas

10. Antagonism between Epidermal Growth Factor and Phorbol Ester Tumor Promoters in Human Breast Cancer Cells
It has been suggested that the phorbol ester tumor promoters act via the receptor-effector system for epidermal growth factor (EGF), since they interact with the EGF receptor system and mimic many of the effects of EGF in cultured cells. We have studied the interaction of phorbol esters with the EGF-responsive MCF-7 human breast cancer cell line. Similar to

11. Nonessential Sequences, Genes, and the Polytene Chromosome Bands of DROSOPHILA MELANOGASTER
From earlier work, there appears to be an underlying one-to-one correspondence of polytene chromosome bands and complementation groups within a sizeable, continuous X-chromosome segment, 3A1–3C7 ( Judd, Shen and Kaufman 1972; Lefevre and Green 1972). However, most of the data supporting this one-to-one relation of bands and genes were gathered from mutant

12. Adaptive alterations in cellular metabolism with malignant transformation.
OBJECTIVE: The authors studied the differences between glutamine and glucose utilization in normal fibroblasts and in fibrosarcoma cells to gain insights into the metabolic changes that may occur during malignant transformation. SUMMARY BACKGROUND DATA: The process of malignant transformation requires that cells acquire and use nutrients efficiently for ener
