Para tanto, adotou-se uma metodologia de identificação de APLs inovadora que compreende, não apenas a análise da concentração locacional e setorial, mas a averiguação da existência de processos de interação, cooperação e aprendizagem. A partir da aplicação de questionários com as empresas do setor evidenciou-se um baixo processo de interação e de cooperação entre asmesmas. Dessa forma, os resultados encontrados indicam que o aglomerado em análise não pode ser caracterizado como um APL consolidado, não conseguindo valer-se das vantagens inerentes ao mesmo, como o partilhamento na aquisição e uso de recursos comuns de produção,

As it is the first contact the tourist has with the place he is visiting, we can consider the landscape as being at the heart of a location’s tourism attractiveness. The landscape is what is seen in a particular place, the way in which the space is arranged, and the range of geographical elements in a place. Landscape can be classified as either natural or urban. As it is a representation of the space, the landscape is a dynamic element that is transformed over time. This article seeks to analyze the urban landscape of Irati – Parana, as a tourism attraction. Its results indicate its significance as a tourism resource. Key words: Landscape; Urban Landscape; Tourism; Irati.

The pyrolytic treatment of those precursors combined with standard size separation techniques (dialysis and filtration), leads to four distinct families of photoluminescent materials in which the emissive signal predominantly arises from C-dots with embedded fluorophores, cyanuric acid-rich C-dots, a blend of molecular fluorophores and a mixture of C-dots with unbound molecular fluorophores, respectively. Within each one of those families the chemical composition and the optical properties of their members can be fine-tuned by adjusting the molar ratio of the reactants. Apart from generating a variety of aqueous dispersions, our approach leads to highly fluorescent powders derived from precursors comprising excessive amounts of urea that is consumed for th...

Our strategy relies on the thermal treatment of ethanolamine (a carbon and nitrogen-rich precursor) well dispersed within a polymer matrix and gives rise to fluorescent C-dot based nanocomposites, without compromising the physicochemical characteristics of the matrix. The strategy affords at least 20% conversion of the precursor towards fluorescent nanoparticles, eliminates the use of toxic chemicals and is thoroughly compatible with melt processing technologies routinely used in industry. While we focus here on polyethylene (PE), polypropylene (PP) and polyethylene glycol (PEG) nanocomposites, the approach is general and applicable to a variety of thermally stable polymers. The C-dots formed in situ within the PEG matrix have diameters in the range 1-40 nm (as revealed by TEM) and exhibit quantum yield 11% in water compared to 3% for the PE-derived nanoparticles.

Circular dichroism was employed to gain insights on the interactions of the building blocks at the molecular level. Quartz crystal microbalance tests were used to monitor in real time the build-up of multilayer coatings, while atomic force microscopy, contact angle and surface zeta potential measurements were performed to assess the surface characteristics of the multilayer assemblies. Remarkably, the nanocoated surfaces show almost 100% reduction in the population of both Escherichia coli and Staphylococcus aureus. The study suggests that Nafion based synergistic platforms can offer an effective line of defence against bacteria, facilitating antimicrobial mechanisms that go beyond the concept of exclusion zone.

B-MWCNTs were characterized using Raman spectroscopy, scanning electron-and transmission electron microscopy, and electrochemical techniques. The results exhibit enhanced response and sensitivity of B-MWCNTs upon modification with AuNPs. Analysis of dopamine (DA) and epinephrine (EP) in presence of uric acid (UA) was investigated on B-MWCNTs/AuNPs in pig blood serum. Limits of detection of 0.20 and 0.30 μM were estimated for DA and EP, respectively. The findings demonstrate that B-MWCNTs/AuNPs is proper for analysis of DA and EP under coexistence of UA.

Efforts on this research area have been focused on assuring isolation between co-resident virtual machines to avoid escaping the sandbox, but less attention has been given to the implications virtualization may pose to the efficiency and quality of random number generation on guests. On Linux distributions, the good provisioning of entropy gathered by the kernel is crucial for the functioning of its random number generator. However, entropy sources may be scarce on virtual machines due to the abstraction implied by the virtualization layer. As a consequence, both the generation speed and the quality of random numbers might drop when compared to hosts. This paper looks into this issue and analyzes the outputs of the /dev/random interface of the Linux kernel on virtual machines. With a well-know statistical library it is shown that the outputs are of high quality and are independently generated, even though they are produced on a slower basis.

The possibility of paying-as-you-go mixed with an on-demand elastic operation is changing the enterprise computing model, shifting on-premises infrastructures to offpremises data centers, accessed over the Internet and managed by cloud hosting providers. Regardless of its advantages, the transition to this computing paradigm raises security concerns, which are the subject of several studies. Besides of the issues derived from web technologies and the Internet, clouds introduce new issues that should be cleared out first in order to further allow the number of cloud deployments to increase. This paper surveys the works on cloud security issues, making a comprehensive review of the literature on the subject. It addresses several key topics, namely vulnerabilities, threats and attacks, proposing a taxonomy for their classification. It also contains a thorough review of the main concepts concerning the security state of cloud environments and discusses several open research topics.
