1. Investigación de diseños de mezcla para producir Ultra High Performance Fiber Reinforced Concrete (UHPFRC) usando ANOVA
ABSTRACT An experimental study is presented to produce Ultra High Performance Fiber Reinforced Concrete (UHPFRC) including industrial waste in the mix, and determine the average compressive strength. The study includes factor arrangements to perform analysis of variance using ANOVA. The controllable factors were: (i) age of the sample; (ii) granulometry of t

2. Caracterização biológica e molecular de recombinantes naturais de HIV-1. / Biological and molecular characterization of HIV-1 natural recombinants.
Recombination during reverse transcription is an important factor promoting HIV-1 diversity and adaptive change, allowing advantageous mutations arising on different genomes to undergo linkage in the same progeny recombinant genome more frequently than what would be expected under random mutation alone. In Brazil, several recombinant viruses were reported, a

3. Controle genético da resistência parcial, adaptabilidade e estabilidade frente à ferrugem asiática da soja / Controle genético da resistência parcial, adaptabilidade e estabilidade frente à ferrugem asiática da soja
Os objetivos principais deste trabalho foram obter informações a respeito do controle genético da herança da resistência parcial à ferrugem asiática em linhagens de soja e avaliar a adaptabilidade e estabilidade fenotípica de linhagens de soja quanto à resistência parcial. Para o estudo do controle genético da resistência parcial foram feitas ava

4. Partial purification and characterization of serine and cysteine proteases of Sitophilus zeamais (Coleoptera: Curculionidae) / Purificação e caracterização parciais de serino e cisteíno proteases de Sitophilus zeamais (Coleoptera: Curculionidae)
Serine and cysteine proteases of a susceptible and two resistant strain (one with a cost associated with resistance and other without cost) of the maize weevil Sitophilus zeamais were partially purified using an affinity column of aprotinin-agarose . The highest purification factor was obtained for the resistant no-cost strain, 51.20x, with a yield of 14.8%

5. Molecular determinants of response and resistance to tyrosine kinase inhibitors (TKIs in patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) gene mutation / Determinantes moleculares de resposta e resistencia aos inibidores da tirosina quinase (TKI) em pacientes com carcinoma de pulmão não pequenas celulas (CPNPC) com mutações no gene do recptor do fator de crescimento epidermico (EGFR)
Most advanced non-small cell lung cancers (NSCLCs) with activating epidermal growth factor receptor (EGFR) mutations (exon 19 deletions or L858R) initially respond to the EGFR tyrosine kinase inhibitors (TKIs) gefitinib and erlotinib. However, over time (median of 6-12 months) most tumors develop acquired resistance to EGFR TKIs. Intense research in these NS

6. A casa de prisão com trabalho da Bahia, 1833-1865. / The house of imprisonment with labour of Bahia, 1833-1865.
The aim of this thesis is to study the origins and initial years of operation of Bahias first penitentiary, known as the Casa de Prisão com Trabalho (Prison-Workhouse), from 1833 to 1865. I examine the debates among various elite groups regarding the adaptation of new ideas about penitentiaries to a slaveholding society as 19th-century Bahia was. I have als

7. AlteraÃÃo bioquÃmica em fator de coagulaÃÃo como causa de trombose venosa profunda â relato de caso clÃnico
Deep venous thrombosis (DVT) in the pediatric population (0-18 year old) has been reported as lower than in adults. In almost half of the children, three or four risk factors for thrombosis are present simultaneously. Even in children with thromboembolic disturbance, thrombosis did not occur spontaneously; the hemostatic defect became apparent because thromb

8. Efeito da adição de farinha de cara (Dioscorea alata L.) na qualidade tecnologica da farinha de trigo de alta extração
The importation of wheat to satisfy a continually growing consumption creates an economic burden, not only in Brazil, but in many other developing nations as well. The partial substitution of a locally-produced flour for part of the wheat can help in alleviating such a strain on the national economy. In the present study, the potentiality of the use of the l

9. Genetic and Molecular Properties of an Infectious Antibiotic Resistance (R) Factor Isolated from Klebsiella
A Klebsiella strain of human origin that was resistant to ampicillin, chloramphenicol, kanamycin, neomycin, streptomycin, and tetracycline was found to have all of these resistances associated with a R factor and a satellite molecular species of deoxyribonucleic acid (DNA) with an average buoyant density of 1.710 in cesium chloride gradients. There was no ev

10. Interbacterial Transfer of R Factor in Humans
In vivo interbacterial transfer of R factor was observed in two patients. Resistance to ampicillin, tetracycline, streptomycin, and chloramphenicol was transferred from Escherichia coli in the intestine of a patient with shigellosis to a Shigella sonnei strain. In a second patient with partial ureteral obstruction, a resistant E. coli strain transferred ampi

11. Origin and direction of replication of the drug resistance plasmid R100.1 and of a resistance transfer factor derivative in synchronized cultures.
The origin and direction of replication of the resistance plasmid R100.1 and its resistance transfer factor derivative, pAR132, were studied by electron microscopy autoradiography of partially denatured molecules and partial denaturation mapping of replicative intermediates. Results of these studies indicate the existence of an origin of replication at 8.8 k

12. Denaturation mapping of R factor deoxyribonucleic acid.
The R factor NR1 consists of two components: a resistance transfer factor which harbors the tetracycline resistance genes (RTF-TC) and the r-determinants component which harbors the other drug resistance genes. Using partial denaturation mapping it is possible to distinguish the RTF-TC region from the r-determinants region of the composite R factor NR1 DNA w
