1. Simultaneous use of direct and reverse flotation in the production of iron ore concentrate plant
Abstract The exploitation of low-grade iron ore deposits represents the current scenario for this business. Thus arise several types of research that aim at improvements and innovations as solutions to such situation. Therefore, herein, suggested is an alternative route for iron ore flotation that targets a higher mass recovery with concentrate within the ma

2. Carboidratos como fonte de compostos para a indústria de química fina
Coal, oil, natural gas, and shale gas are biomass that is formed millions of years ago. These are non-renewable and depleting, even considering the recent discovery of new sources of oil in the presalt and new technologies for the exploitation of shale deposits. Currently, these raw materials are used as a source of energy production and are also important f

3. Architecture for generic detection of machine code injection in computer networks
Since the creation of public exploitation frameworks, advanced payloads are used in computer attacks. The attacks generally employ evasion techniques, have anti-forensics capabilities, and use target machines as pivots to reach other machines in the network. The attacks also use polymorphic malicious code that automatically transforms themselves in semantica

4. Seed lipases: sources, applications and properties - a review
This paper provides an overview regarding the main aspects of seed lipases, such as the reactions catalyzed, physiological functions, specificities, sources and applications. Lipases are ubiquitous in nature and are produced by several plants, animals and microorganisms. These enzymes exhibit several very interesting features, such as low cost and easy purif

5. Gestão de recursos e reservas para aumento do aproveitamento do folhelho pirobetuminoso e aumento da recuperação de sua matéria orgânica na forma dos derivados óleo e gás. / Management of resources and reserves for increase the use oil shale and increase of recovery of your organic matter in form of oil and gas derivatives.
Este trabalho trata sobre o aproveitamento de reservas minerais através dos conceitos de completa extração e adequada utilização do minério, considerando estes conceitos como parte da gestão de recursos e reservas, e como elementos que poderão contribuir para o aumento da vida útil do empreendimento mineiro e para redução de custos unitários. A g

6. Partição da extração da água do solo por plantas entre camadas com teores de água distintos / Partition of root water extraction between soil layers with distinct water contents
Water shortage is one of the most limiting factors for agricultural production. The understanding of factors that rule the extraction of soil water by plants and its distribution along the root system under contrasting hydraulic conditions is important for fine-tuning hydrological models which are a reference for crop growth models, meteorological models, am

7. The European Bioinformatics Institute's data resources: towards systems biology
Genomic and post-genomic biological research has provided fine-grain insights into the molecular processes of life, but also threatens to drown biomedical researchers in data. Moreover, as new high-throughput technologies are developed, the types of data that are gathered en masse are diversifying. The need to collect, store and curate all this information i

8. In Situ Accessibility of Escherichia coli 23S rRNA to Fluorescently Labeled Oligonucleotide Probes
One of the main causes of failure of fluorescence in situ hybridization with rRNA-targeted oligonucleotides, besides low cellular ribosome content and impermeability of cell walls, is the inaccessibility of probe target sites due to higher-order structure of the ribosome. Analogous to a study on the 16S rRNA (B. M. Fuchs, G. Wallner, W. Beisker, I. Schwippl,

9. In Vivo Production of Artificial Nonribosomal Peptide Products in the Heterologous Host Escherichia coli
Nonribosomal peptide synthetases represent the enzymatic assembly lines for the biosynthesis of pharmacologically relevant natural peptides, e.g., cyclosporine, vancomycin, and penicillin. Due to their modular organization, in which every module accounts for the incorporation of a single amino acid, artificial assembly lines for the production of novel pepti
