1. Generation of Photovoltaic Solar Energy. Evaluation of the Demand Curve with the Insert of Grid-connected Photovoltaic Power System at CINDACTA II, Curitiba-PR, Brazil.
ABSTRACT Unlike some countries, Brazil has a predominantly hydraulic energy matrix, a clean and renewable source. But, in recent years, both the non-renewal of the normal volumes of water in the reservoirs and the lack of consciousness in the consumption of water and energy have placed the country in a critical state of energy supply leading to many intensiv

2. Fatores de influência na definição de modalidades de contratação em projetos. / Factors influencing the choice of contract types in projects.
In the current context of competitiveness and rationalization in business, most of the organizations do not have all the necessary resources to develop their projects, requiring the participation of suppliers of materials, equipment, services, systems, solutions or even the whole project. Thanks to this, the choice on contract type for each item or package t

3. Aquisições, contratações e suprimentos em projetos: um modelo para avaliação das práticas de gestão. / Procurement, contracting and supplying in projects: a model for management practices assessment.
O gerenciamento de aquisições vem se tornando um dos aspectos mais importantes do gerenciamento de projetos, acompanhando a tendência das organizações de se dedicarem mais à sua vocação competitiva e passarem a adquirir de fontes externas os recursos, materiais, equipamentos, sistemas, soluções e serviços necessários à realização de seus proje

4. Criação da matéria em cosmologias com velocidade da luz variável e eletrônico não-linear
In this work we obtain the cosmological solutions and investigate the thermodynamics of matter creation in two diferent contexts. In the first we propose a cosmological model with a time varying speed of light c. We consider two diferent time dependence of c for a at Friedmann-Robertson- Walker (FRW) universe. We write the energy conservation law arising fro

5. Impaired metabolic modulation of α-adrenergic vasoconstriction in dystrophin-deficient skeletal muscle
The neuronal isoform of nitric oxide synthase (nNOS) is highly expressed in mammalian skeletal muscle, but its functional role has not been defined. NO has been implicated in the local metabolic regulation of blood flow in contracting skeletal muscle in part by antagonizing sympathetic vasoconstriction. We therefore hypothesized that nNOS in skeletal muscle

6. Millisecond time-resolved changes in x-ray reflections from contracting muscle during rapid mechanical transients, recorded using synchrotron radiation.
Low-angle x-ray diffraction diagrams have been recorded from frog sartorius muscles by using synchrotron radiation as a high-intensity x-ray source. This has enabled changes in some of the principal reflections of interest to be followed with a time resolution of 1 ms, during small but very rapid length changes imposed on a contracting muscle. The 143-A meri

7. Molecular Identification and Epidemiological Tracing of Pasteurella multocida Meningitis in a Baby
We report a case of Pasteurella multocida meningitis in a 1-month-old baby exposed to close contact with two dogs and a cat but without any known history of injury by these animals. 16S rRNA gene sequencing of the isolate from the baby allowed identification at the subspecies level and pointed to the cat as a possible source of infection. Molecular typing of

8. Endothelium-dependent contractions and endothelial dysfunction in human hypertension
The endothelium is a crucial regulator of vascular physiology, producing in healthy conditions several substances with a potent antiatherosclerotic properties. Accordingly, the presence of endothelial dysfunction is associated with subclinical atherosclerosis and with an increased future risk of cardiovascular events. A large body of evidence supports the fu

9. X-ray diffraction evidence for the extensibility of actin and myosin filaments during muscle contraction.
To clarify the extensibility of thin actin and thick myosin filaments in muscle, we examined the spacings of actin and myosin filament-based reflections in x-ray diffraction patterns at high resolution during isometric contraction of frog skeletal muscles and steady lengthening of the active muscles using synchrotron radiation as an intense x-ray source and

10. Steady-state force-velocity relation in the ATP-dependent sliding movement of myosin-coated beads on actin cables in vitro studied with a centrifuge microscope.
To eliminate the gap between the biochemistry of actomyosin in solution and the physiology of contracting muscle, we developed an in vitro force-movement assay system in which the steady-state force-velocity relation in the actin-myosin interaction can be studied. The assay system consists of the internodal cells of an alga, Nitellopsis obtusa, containing we

11. Glucose metabolism distal to a critical coronary stenosis in a canine model of low-flow myocardial ischemia.
Myocardial regions perfused through a coronary stenosis may cease contracting, but remain viable. Clinical observations suggest that increased glucose utilization may be an adaptive mechanism in such "hibernating" regions. In this study, we used a combination of 13C-NMR spectroscopy, GC-MS analysis, and tissue biochemical measurements to track glucose throug
