1. HOTSPOT STABILIZATION OF GOLD NANOPARTICLES FOR APPLICATION OF QUANTITATIVE SERS IN BIOANALYTICAL SYSTEMS
A complete procedure including synthesizing gold nanoparticles and further hotspots stabilization is presented. Colloidal gold synthesis followed a citrate reducing reaction, then, an ideal condition for SERS enhancement with quantitative purposes was reached by searching equilibrium between salt- and analyte-induced aggregation. Under this condition, a mild

2. PHYSICAL, MECHANICAL AND THERMAL BEHAVIOR OF ADOBE STABILIZED WITH “SYNTHETIC TERMITE SALIVA”
ABSTRACT Adobe is an efficient construction material for several reasons, such as its thermal comfort, sustainability, and lower energy cost, as well as the simplicity of its production and execution. However, challenges such as water absorption, capillarity, and compressive strength should be investigated to improve its physical and mechanical properties. �

3. Evolución microestructural in-situ a alta temperatura de depósitos de soldadura de aceros 9Cr con diferentes contenidos de boro
ABSTRACT New alloys have been developed for enhancing the performance of the equipment used in thermoelectric power generation industry. With the objective of increasing the creep resistance of these materials, changes in the content of some microalloying elements were carried out. Boron bearing in creep strength enhanced 9Cr steel (CSE9Cr) welds improved ma

4. Manifestaciones de la crise en America Latina y las paradojas del neodesarrolismo argentino
The worsening global crisis has made it clear that the Latin American economy's power to contain turbulence is limited. UNASUL's central role has increased, but the stabilization fund has not been able to prevent the foreign influence on the finances and stagnation of the Banco do Sul. Its enormous currency reserves will end up bailing out European banks if

5. A swirler stabilized combustion chamber for a micro-gas turbine fuelled with natural gas
Micro-gas turbines are a good alternative for on-site power generation, since their operation is very reliable. The possibility of operating with various fuels increases versatility and, as a result, the usage of these devices. Focusing on a performance improvement of a tri-fuel low-cost micro-gas turbine, this work presents investigations of the inner flow

7. Bioprospecção de genes envolvidos na síntese de biossurfactantes a apartir de microbiota de resevatórios de petróleo / Bioprospection of genes involved in the synthesis of biosurfactants from braziliam petroleum reservoirs microbial communities
Bioemulsifiers or biosurfactants are compounds produced by microorganisms which enhance the bioavailability of hydrophobic substances promoting the stabilization of substances with different polarities, like oil-in-water emulsion occurring in petroleum reservoirs. The samples used in this work were collected in the Potiguar Basin (RN, Brazil), and employed a

8. Distribuição assintótica do máximo estabilizado em modelos de mistura finita
Neste trabalho estudamos o comportamento assintótico do máximo de variáveis aleatórias independentes e identicamente distribuídas estabilizado por transformações gerais contínuas estritamente monótonas. Apresentamos os principais resultados desenvolvidos por E. Pantcheva (1984), que estendem resultados amplamente conhecidos da teoria assintótica ex

10. Estabilização de oscilações de potencia de linhas de intercambio atraves de um elo de corrente continua / Stabilization of power lines interchange oscillations through a direct-current link
When an interconnected alternate-current power system suffers variations of loads, its frequency can exhibit an oscillatory behavior. If this system possesses a direct-current link in parallel with the inter-tie lines, this effect could be decreased, due to the link current controller action. This work presents a study that evaluates the efficiency of DC lin

11. O poder legislativo na verificação da legitimidade constitucional do processo de construção das leis
It is known that, in the Democratic State of Law paradigm, one of the most instigating themes is the legitimity of the Law. It justifies the interest in reflecting about the Legislative Process instituted by the Brasilian 1988 Constitution, more specifically field of the constitutionality control as away to guaranty of the legitimity of the Law. The research
