1. Modelo Regulatório e risco de mercado: uma comparação entre as empresas de distribuição de gás e energia elétrica norte americanas e suas congêneres no Brasil, Chile e Argentina / Regulatory model and market risk: a comparison between the distribution companies of gas and electricity and their North American counterparts in Brazil, Chile and Argentina
A legislação brasileira estabelece que o Estado tem a obrigação de preservar o equilíbrio econômico financeiro das concessões de serviços públicos. Assim o Estado deve garantir que as tarifas dessas concessões sejam capazes de cobrir os seus custos operacionais e ainda ofereçam um retorno justo para os agentes privados que nelas investiram. Nas co

2. Glutamine and antioxidant metabolism during adventitious organogenesis of Ananas comosus leaves / Glutamina e metabolismo antioxidante durante a organogênese adventícia em folhas de Ananas comosus
A positive influence of glutamine on organogenesis of in vitro cultured plant tissues has been demonstrated by several studies. It is well known that the endogenous synthesis of phytohormones can be influenced by nitrogen sources, although it is not completely established in which way glutamine acts in this process. The addition of this amino acid to the cul

3. TRÊS ENSAIOS SOBRE A METODOLOGIA DE APREÇAMENTO DE ATIVOS UTILIZANDO OPÇÕES REAIS / THREE ESSAYS ON ASSET PRICING APPLYING REAL OPTIONS METHODOLOGY
The dissertation presents three economic essays examining situations where the real options approach can be useful in the definition of regulatory policies, investment strategies and pricing of sovereign risk. The first essay considers the new regulation oriented to interconnection costs of telecommunications networks and proposes adjustments in calculating

4. O fator redutor da tarifa de distribuiÃÃo de energia elÃtrica: um enfoque utilizando a anÃlise por envoltÃria de dados - DEA
The tariffs that the Brazilian electric distribution companies charge are defined by ANEEL and are subjected to a price cap. Its tariffs revisions occur each 4 years and are allowed to rise in line with inflation. Simultaneously they are also required to decrease by a X Factor. This X factor reflects the level of economic inefficiency in each company. This f

5. Effects of light fluence and wavelength on expression of the gene encoding cucumber hydroxypyruvate reductase.
We have investigated the regulation of cucumber (Cucumis sativus) hydroxypyruvate reductase mRNA abundance in response to white-, red-, and far-red-light treatments. Following irradiation of dark-adapted cucumber seedlings with 15 min to 4 h of either white or red light and return to darkness, the mRNA level for the gene encoding hydroxypyruvate reductase (H

6. Neural Regulation of Insulin Secretion in the Dog
The effects of stimulation of the mixed autonomic nerve to the dog pancreas has been studied under conditions in which both pancreaticoduodenal vein blood flow and insulin concentration were determined. Stimulation resulted in increased insulin output, which was blocked by prior administration of atropine. Blood flow was reduced by stimulation in proportion

7. Regulation of SOS mutagenesis by proteolysis.
DNA damage-inducible mutagenesis in Escherichia coli is largely dependent upon the activity of the UmuD (UmuD') and UmuC proteins. The intracellular level of these proteins is tightly regulated at both the transcriptional and the posttranslational levels. Such regulation presumably allows cells to deal with DNA damage via error-free repair pathways before be

8. Transcriptional and post-transcriptional processes regulate expression of RNA encoding the small subunit of ribulose-1,5-biphosphate carboxylase differently in petunia and in soybean.
The effects of white light, far-red light and darkness on the in vitro transcription and RNA levels of the small subunit of ribulose-1,5-bisphosphate carboxylase (rbcS) were investigated in petunia and in soybean. In petunia plants treated with 48 hours of darkness the in vitro transcription rate of two of the rbcS subfamilies of petunia, rbcS A and rbcS C,

9. Transcriptional and posttranscriptional control of c-myc gene expression in WEHI 231 cells.
Incubation of WEHI 231 cells, derived from a murine B-cell lymphoma, with antisera directed against its surface immunoglobulin results in the inhibition of growth within 24 h. Previously, we demonstrated that this treatment selectively affects cytoplasmic levels of c-myc mRNA (J. E. McCormack, V. H. Pepe, R. B. Kent, M. Dean, A. Marshak-Rothstein, and G. E.

10. Regulation of intracellular pH in reticulospinal neurones of the lamprey, Petromyzon marinus.
1. The regulation of intracellular pH (pHi) in lamprey reticulospinal neurones was investigated with pH-sensitive micro-electrodes based on a neutral carrier liquid membrane. Experiments were performed using an in vitro brain-stem preparation. 2. In HEPES-buffered solutions, extracellular pH (pHo) was consistently more acidic than the pH of the bathing solut

11. Major intracellular cations and growth control: Correspondence among magnesium content, protein synthesis, and the onset of DNA synthesis in BALB/c3T3 cells
Omission of Ca2+ from the medium of confluent BALB/c3T3 cells for a period of 17 hr causes a large decrease in the number of cells synthesizing DNA. This effect is reversed by raising the Mg2+ concentration of the medium to 20 mM. However, if the [Mg2+] is greater than 20 mM (“ultra-high” Mg2+), there is again a decrease in the number of cells synthesizi

12. Intracellular chloride regulation in amphibian dorsal root ganglion neurones studied with ion-selective microelectrodes.
1. Intracellular Cl- activity (aiCl) and membrane potential (Em) were measured in frog dorsal root ganglion neurones (DRG neurones) using double-barrelled Cl- -selective microelectrodes. In standard Ringer solution buffered with HEPES (5 mM), equilibrated with air or 100% O2, the resting membrane potential was -57.7 +/- 1.0 mV and aiCl was 23.6 +/- 1.0 mM (n
