1. A dynamic scheduling runtime and tuning system for heterogeneous multi and many-core desktop platforms / Um sistema de escalonamento dinâmico e tuning em tempo de execução para plataformas desktop heterogêneas de múltiplos núcleos
Atualmente, o computador pessoal (PC) moderno poder ser considerado como um cluster heterogênedo de um nodo, o qual processa simultâneamente inúmeras tarefas provenientes das aplicações. O PC pode ser composto por Unidades de Processamento (PUs) assimétricas, como a Unidade Central de Processamento (CPU), composta de múltiplos núcleos, a Unidade de P

2. A service-based access selection algorithm for always best connected networks
It is expected that future wireless systems will consist of several distinct radio access technologies, such as WCDMA/HSDPA, GSM/EDGE/GPRS, WLAN and others, forming a mobile multi-access system offering advanced multimedia services. Together with the evermore availability of user terminals capable of operating with more than one communication technology, use

3. Expressão imunohistoquimica da isoforma neuronal da sintase do oxido nitrico no neocortex cerebral humano normal e em displasias corticais
Nitric oxide (NO) is a diffusible and reactive molecular messenger in the nervous, vascular and immune systems. NO is not stored, but rather synthesized on demand from the amino acid L-arginine by a family of isoenzymes, the nitric oxide synthases (NOS). NO is a mediator of many physiological roles. In the brain, NO acts as a neurotransmitter/neuromodulator

4. PROCESS CONTROL SYSTEMS : DEPENDABILITY AND PERFORMANCE MODELING
Today, a wide variety of computer systems are required to react automatically to various events generated by external processes and/or human operators. An important class of these process control systems, called hard real-time systems, need to respond to events under severe timing constraints expressed in terms of deadlines and earliest starting times. In ge

5. Physicochemical surface properties of Escherichia coli strains isolated from different types of urinary tract infections.
Escherichia coli strains isolated from three groups of patients with urinary tract infections, such as acute pyelonephritis, acute cystitis, and asymptomatic bacteriuria, were analyzed with respect to their physicochemical surface properties by means of polymer two-phase partitioning in dextran-polyethylene glycol systems and hydrophobic interaction chromato

6. Adrenocorticotropin-like and alpha-melanotropin-like peptides in a subpopulation of human gastrin cell granules: bioassay, immunoassay, and immunocytochemical evidence.
Adrenocorticotropin (ACTH)-like and alpha-melanotropin (alpha-MSH)-like peptides have been localized to a subpopulation of cytoplasmic (secretory) granules of human antropyloric gastric cells and of fetal and neoplastic gastrin cells. These granules also store gastrin and belong to the electron-dense variety of gastrin cell granules. Gastrin cells also conta

7. Differentiation of an interleukin 3-dependent precursor B-cell clone into immunoglobulin-producing cells in vitro.
Precursors to B-cell lines with immunoglobulin genes in the germ-line context have been shown to be capable of generating mature B cells in vivo. We report here that an interleukin 3-dependent precursor B-cell line, LyD9, differentiated in vitro into mature B cells, producing IgM and IgG by coculture with bone marrow accessory (or stroma) cells or with dendr

8. Recombinant retroviral systems for the analysis of drug resistant HIV.
Two recombinant retroviral systems are described that can be used to analyze antiretroviral drug activity and HIV breakthrough (replication in the presence of the drug). The first system utilizes a recombinant HIV encoding beta-galactosidase as a reporter gene (HIV-LacZ). The defective HIV-LacZ virus is produced in COS cells after co-transfection of a plasmi

9. Isoproterenol stimulates shift of G proteins from plasma membrane to pinocytotic vesicles in rat adipocytes: a possible means of signal dissemination.
Guanine nucleotide-binding regulatory proteins (G proteins) are linked to a large number of surface membrane receptors and appear to regulate a variety of effector systems located both in the plasma membrane and in other parts of the cell. The mechanism of the disseminative actions of G proteins remains obscure. During an investigation of the fate of two typ

10. Expression of adenovirus-2 early region 4: assignment of the early region 4 polypeptides to their respective mRNAs, using in vitro translation.
Adenovirus-2 early region 4 (E4; map positions 91.3 to 99.1) encodes six 5' and 3' coterminal, differently spliced mRNAs, which are 2.5, 2.1, 1.8, 1.5, 1.2, and 0.8 kilobases (kb) long. Hybridization selection with five cloned viral DNA fragments that hybridize with subsets of E4 mRNAs was used to purify these six mRNAs and a previously unreported 3.0-kb mRN
