13. Influencia do ambiente termico, aereo e acustico de uma maternidade e creche de suinos nas condições laborais do trabalhador / Influence of the farrowing and growing swine thermal, air and acoustic environment in labor conditions of the worker
Swine housing project nowadays has presented some gaps related to the impact of the resulting environment in both animal production and the labor health and security. Future rural constructions might provide more than just shade offer to animal confinement, as the animal welfare demands by consumers increased considerably enhancing the use of new design conc

14. Editorial
The present article discusses crucial morpho-syntactic aspects of relative constructions in Shipibo-Konibo, a Panoan language spoken in the Peruvian Amazon. The analysis is predominantly based on data extracted from spontaneous texts. Shipibo-Konibo exhibits a number of features that are uncommon in the languages of the world, such as the coexistence of pren

15. Parâmetros urbanísticos para habitação de interesse social: uma análise crítica para as Rocas em Natal/RN
Through the comparative critical analysis of the demanded urbanistic parameters in the legislation and of the urbanistic index found in the Rocas neighbourhood, having as study object the already consolidated constructions of residential use, intended to demonstrate that the neighbourhood needes specific norms and that the limits established for recognition

16. O USO DO AÇO NAS INTERVENÇÕES EM EDIFICAÇÕES HISTÓRICAS: INTERFACES DA ARQUITETURA E DA ESTRUTURA
The conscience of preserving the architectural patrimony made possible for the contemporary intervention projects an increasing valuation of the preexisting. These interventions seek establishing a dialogue between the present and the past, allied to a search of adequate techniques that allow to differentiate these times, exposing technological changes and m

17. Multibiorreações e suas aplicações para as sinteses de compostos enantiomericamente puros / Multibioreactions applied to the syntheses of enantiomerically pure compounds
The utilization of enzymes for organic compound transformations is an alternative to classical syntheses. Enzymes are used as biocatalysts for the syntheses in vitro of asymmetric compounds because they are intrinsically chiral and result in high catalytic efficiency. In front of the biodiversity of existing microorganisms in Nature and of the necessity to d

18. IMPACTOS AMBIENTAIS NA MICROBACIA DO RIO VACACAÍ-MIRIM EM SANTA MARIA RS.
The renewable natural resources sustain the balance between the man and the nature. The destruction of one of those resources represents the unbalance and the man s future destruction. Such resources accomplish a social function to the man s service and of the society. Starting from the moment that the man began to use the renewable natural resources in thei

19. Use of lacZ fusions to measure in vivo expression of the first three genes of the Escherichia coli unc operon.
We have constructed in-frame lacZ protein fusions to the first three genes of the Escherichia coli unc operon, which codes for the subunits of the proton-translocating ATPase. We have used these constructions to measure the relative in vivo expression of these genes. The second and third genes, uncB and uncE, which code for the a and c subunits of the F0 sec

20. Cloning of the two pyruvate kinase isoenzyme structural genes from Escherichia coli: the relative roles of these enzymes in pyruvate biosynthesis.
We report the cloning of the pykA and pykF genes from Escherichia coli, which code for the two pyruvate kinase isoenzymes (ATP:pyruvate 2-O-phosphotransferases; EC 2.7.1.40) in this microorganism. These genes were insertionally inactivated with antibiotic resistance markers and utilized to interrupt one or both pyk genes in the E. coli chromosome. With these

21. Functional analysis of the steroid hormone control region of mouse mammary tumor virus.
Gene fusions between the mouse mammary tumor virus long terminal repeat and the E. coli lacZ gene have been shown to exhibit hormone dependent expression of beta-galactosidase activity. These constructions were used in transient expression experiments to assess the effects of specific modifications introduced into the region upstream of the transcription ini

22. Expression of Alcaligenes eutrophus Flavohemoprotein and Engineered Vitreoscilla Hemoglobin-Reductase Fusion Protein for Improved Hypoxic Growth of Escherichia coli
Expression of the vhb gene encoding hemoglobin from Vitreoscilla sp. (VHb) in several organisms has been shown to improve microaerobic cell growth and enhance oxygen-dependent product formation. The amino-terminal hemoglobin domain of the flavohemoprotein (FHP) of the gram-negative hydrogen-oxidizing bacterium Alcaligenes eutrophus has 51% sequence homology

23. In vivo transcriptional analysis of the TATA-less promoter of the Drosophila melanogaster vermilion gene.
Transcriptional regulation of the TATA-less promoter of the Drosophila melanogaster vermilion (v) gene was investigated. Developmental Northern (RNA) blot analysis showed that v transcripts accumulate during late embryo, larval, and adult stages. Sequences that control expression in adults were delineated by analyzing a series of 5' and 3' deletion construct

24. Chimeric 3-hydroxy-3-methylglutaryl coenzyme A reductase-dihydrofolate reductase genes display bidirectional expression and unidirectional regulation in stably transfected cells.
We have constructed hybrid dihydrofolate reductase (DHFR) genes which are controlled by the sterol-responsive hamster 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase promoter. Stable transfection frequencies of these chimeric templates into a DHFR-deficient Chinese hamster cell line indicate that the HMG CoA reductase promoter fragment confers DHFR
