1. Green biosynthesized Satureja rechingeri Jamzad-Ag/poly vinyl alcohol film: quality improvement of Oncorhynchus mykiss fillet during refrigerated storage
Abstract The nanosilver food packaging films were developed by polyvinyl alcohol activated with Satureja rechingeri extract (S-AgNPs/PVA) using the solvent casting to evaluate the freshness of Oncorhynchus mykiss fillets during 14 days at the refrigerated temperature. The 160 pieces of fish were enfolded in 4 types of films as main group-series. The main com

2. Reduction of Aqueous Ag+ Steered by Electrochemical Plasma: Connecting the Bulk pH Variation with the Reaction Pathways for Hydrated Electrons
Reduction of silver cations followed by nanoparticle (Ag-NPs) synthesis is a model process to understand the reduction mechanism induced by a discharge over an aqueous surface, termed electrochemical plasma. This work aims at studying the silver reduction reaction steered by electrochemical plasma in the presence of other chemically active plasma-related int

3. Evaluation of E. coli inhibition by plain and polymer-coated silver nanoparticles
ABSTRACT Escherichia coli causes various ailments such as septicemia, enteritis, foodborne illnesses, and urinary tract infections which are of concern in the public health field due to antibiotic resistance. Silver nanoparticles (AgNP) are known for their biocompatibility and antibacterial activity, and may prove to be an alternative method of treatment, es

4. Heterogeneous photo-Fenton and photocatalytic degradation studies of 2-chloro-4-nitrophenol (2Cl4NP) using foundry sand and TiO2 coated cement/clay beads
ABSTRACT Cement and clay beads coated with TiO2were used for the photo-degradation and mineralization of 2-chloro-4-nitrophenol (2Cl4NP) along with a heterogeneous solar photo-Fenton process using foundry sand (FS) as the iron source. The degradation process was optimized using slurry photocatalysis where 96% degradation of 2Cl4NP was achieved in 120 min at

5. MULTI-VEHICLE COVERING TOUR PROBLEM: BUILDING ROUTES FOR URBAN PATROLLING
ABSTRACT In this paper we study a particular aspect of the urban community policing: routine patrol route planning. We seek routes that guarantee visibility, as this has a sizable impact on the community perceived safety, allowing quick emergency responses and providing surveillance of selected sites (e.g., hospitals, schools). The planning is restricted to

6. Solving the Integrated Schedule Generation and Fleet Assignment Problem: an ACOBased Metaheuristic Approach
Abstract Traditionally, the initial steps on airline planning – Schedule Generation and Fleet Assignment problems – are solved separately. This traditional approach usually leads to suboptimal solutions, since flight profitability – the decision criteria to schedule a flight – depends on what aircraft type will be used on that flight. On the other ha

7. ECM, raising &control infinitival small clauses: case assignment in english and brazilian portuguese revisited in Chomsky s minimalist program
Esta Tese defende que as sentenças encaixadas do tipo infinitivas flexionadas (Inflected Infinitival Small Clauses - IISCs) em Português Brasileiro (PB) não são tratadas de forma adequada via qualquer abordagem com base em movimento, como a Teoria de Controle via Movimento (Movement Theory of Control - MTC), ao contrário das mesmas infinitivas encaixada

8. Análise da distribuição do número de operações de resolvedores SAT / Distribution\ s analysis of operations\ s number of SAT solvers
No estudo da complexidade de problemas computacionais destacam-se duas classes conhecidas como P e NP. A questao P=NP e um dos maiores problemas nao resolvidos em Ciencia da Compu- tacao teorica e Matematica contemporanea. O problema SAT foi o primeiro problema reconhecido como NP-completo e consiste em verificar se uma determinada formula da logica proposic

9. DINÂMICA DO FÓSFORO NA INTEGRAÇÃO LAVOURA-PECUÁRIA SOB SISTEMA PLANTIO DIRETO / Phosphurus dynamic in crop livestock integration under notillage.
The necessity to preserve the soil, coupled with the constant search for lower production costs and increased productivity resulted in the use no-tillage (NT). Efficient technique in the preservation and use of highly weathered soils (tropical and subtropical soils). However, only the continuous cultivation of monocultures has been implicated in reduced prof

10. Avaliação da resposta à teriparida em pacientes portadores de osteoporose pseudoglioma. / Evaluation of response to teriparida in patients with osteoporosis pseudogliom.
INTRODUCTION: Osteoporosis Pseudoglioma (OPPG) is characterized by severe juvenile-onset osteoporosis and ocular abnormalities. It is caused by one of several inactivating mutations in LRP5, a gene importantly involved in bone formation. OBJECTIVE: The objective of this study was to evaluate the efficacy of teriparatide in a young man with OPPG. PATIENT AND

11. Identificação de genes e o Problema do Alinhamento Spliced Múltiplo
The gene prediction in DNA sequences of eukariotic organisms is still an open problem in Bioinformatics. The sequence comparison based approach is commonly used in the search of solutions for this problem. Several different combinations of sequences are being used by gene recognition tools and in this work we propose the comparison of many cDNA sequences wit

12. Algoritmos para escalonamento de tarefas dependentes representadas por grafos acíclicos direcionados em grades computacionais / Scheduling algorithms for dependent tasks represented by directed acyclic graphs on computational grids
Computational grids are potentially large distributed systems composed of heterogeneous resources connected by a network with heterogeneous links. These systems became largely used in the execution of tasks which require large processing capacities. Because they are shared systems, task submission in grids independently originate from a number of users, lead
