1. Private Equity and Venture Capital Funds: What Drives the Demand and Supply?
Abstract This study investigates determinants for the demand and supply for PE/VC funds. Six factors were identified through Factor Analysis: Economic Activity, Development of Stock Markets, Corporate Governance, Social and Environmental Development, Entrepreneurship and Taxation. These factors were defined through 25 variables and transformed into five fact

2. Impinging flow parallel plates heat sinks / Dissipadores termicos de placas paralelas com influxo de topo
The parallel plates heat sinks with top inlet and side exit constitute an enhanced heat transfer alternative for the local removal of electric power dissipation in microprocessors. In the present work, three parallel plates heat sinks were built and tested with variable airflow under the conditions of top inlet and side exit. The experimental results were co

3. THE SPACE THE SYMBOLIC IN VERÃO NO AQUÁRIO / O ESPAÇO O SIMBÓLICO EM VERÃO NO AQUÁRIO
In Verão no Aquário, the space, a recurrent element in Lygia Fagundes Telles fiction, plays a significant role both in the characters composition and in the atmosphere that surrounds them. Through the space, aspects such as anxiety, isolation, imprisionment as well as the conflicting and repressed emotions that involve the protagonist are highlighted in a

4. Biologia de Neotrioza tavaresi Crawford, 1925 (Hemiptera, Psyllidae), galhador da folha do araçazeiro (Psidium cattleianum)
Biology of the leaf gall inducer Neotrioza tavaresi Crawford, 1925 (Hemiptera, Psyllidae) on strawberry guava tree (Psidium cattleianum). A field study was conducted in Curitiba region, State of Paraná, southern Brazil, to describe the life cycle of Neotrioza tavaresi Crawford, 1925, a leaf galling insect in strawberry guava trees (Psidium cattleianum).

5. Características operacionais de praças de arrecadação de pedágio / Toll plazas operational characteristics
The research objective was to analyze the operation of toll plazas in order to give subsidies for its project as well as to establish parameters and procedures to evaluate the service level. The data were collected in five toll plazas in the state of São Paulo, operated in rural highways. The operational aspects studied were: the vehicle arrival process; th

6. Identification of a functional water channel in cytochrome P450 enzymes
Cytochrome P450 enzymes are monooxygenases that contain a functional heme b group linked to a conserved cysteine with a thiolate bond. In the native state, the central iron atom is hexacoordinated with a covalently bound water molecule. The exclusion of solvent molecules from the active site is essential for efficient enzymatic function. Upon substrate bindi

7. The structure of bovine brain myelin proteolipid and its organization in myelin.
A model, based on amino acid sequence data, is proposed for the organization of the myelin proteolipid in myelin membrane. The model has three distinctive features: three trans-membrane segments that traverse the lipid bilayer, two cis-membrane domains that enter and exit the same side of the membrane, and a highly charged segment resembling myelin basic pro

8. Comparison of the dynamics of substrate access channels in three cytochrome P450s reveals different opening mechanisms and a novel functional role for a buried arginine
Understanding the mechanism and specificity of substrate binding in the cytochrome P450 (P450) superfamily is an important step toward explaining its key role in drug metabolism, toxicity, xenobiotic degradation, and several biosynthetic pathways. Here we investigate the ligand exit pathways and mechanisms of P450cam (CYP101), P450BM-3 (CYP102), and P450eryF

9. Structure of the periplasmic component of a bacterial drug efflux pump
Multidrug resistance among Gram-negative bacteria is conferred by three-component membrane pumps that expel diverse antibiotics from the cell. These efflux pumps consist of an inner membrane transporter such as the AcrB proton antiporter, an outer membrane exit duct of the TolC family, and a periplasmic protein known as the adaptor. We present the x-ray stru

10. Binding Site of the Bridged Macrolides in the Escherichia coli Ribosome
Ketolides represent the latest group of macrolide antibiotics. Tight binding of ketolides to the ribosome appears to correlate with the presence of an extended alkyl-aryl side chain. Recently developed 6,11-bridged bicyclic ketolides extend the spectrum of platforms used to generate new potent macrolides with extended alkyl-aryl side chains. The purpose of t

11. Localization of 5' and 3' ends of the ribosome-bound segment of template polynucleotides by immune electron microscopy.
Poly(U) with an average chain length of 40-70 nucleotides was modified at the 5'- or 3'-terminal residues with 2,4-dinitrophenyl derivatives. The modified poly(U) was used to form 30S.poly(U) or 70S.poly(U).Phe-tRNA complexes. Localization of the 5' and 3' ends of the template polynucleotide on the 30S subunit and the 70S ribosome was performed by immune ele

12. Inhibition of the Bicarbonate Exit Step in Urinary Acidification by a Disulfonic Stilbene
Acidification of the luminal solution by the isolated turtle bladder involves H+ secretion by a pump at the luminal membrane. The OH− dissociated in this process reacts with CO2 and forms HCO3− which moves passively out of the cell across the serosal cell membrane. In the present study, this exit step for HCO3− was inhibited by serosal addition of the
