1. Household Infrared Technology as an Energy-Efficient Approach to Achieve C-Cπ Bond Construction Reactions
We examined the ability of short-wave infrared (IR) light in the λ1.5-3.0 μm region of the infrared emission spectrum to accomplish C-Cπ bond construction reaction between π-excessive azaheteroaromatic and different carbonyl substrates supported on a bentonitic clay catalyst in solventless condition via a three-component condensation reaction. Preliminar

2. Characterization of Otto Chips by Particle Swarm Optimization
Abstract Recently a surface plasmon resonance (SPR) optical sensor, based on the Otto configuration — the Otto chip — has been developed. One essential step in the quality control of the fabrication process is characterization of the active region of several devices in a batch. Characterization is done by measuring the angular spectrum of the optical re

3. A broad-spectrum beta-lactam-sparing stewardship program in a middle-income country public hospital: antibiotic use and expenditure outcomes and antimicrobial susceptibility profiles
ABSTRACT Background: Antimicrobial stewardship programs are an efficient way to reduce inappropriate use of antimicrobials and costs; however, supporting data are scarce in middle-income countries. The aim of this study was to evaluate antibiotic use, bacterial susceptibility profiles, and the economic impact following implementation of a broad-spectrum bet

4. Strategies of chemical management for weed control in cassava
ABSTRACT The use of strategies such as sequential applications and mixtures may increase the control spectrum and the residual effect of chemical control of weed in the cassava crop. Thus, the objective was to evaluate the selectivity and efficacy of sequential applications and tank mixture of herbicides in the control of weed in the cassava crop cultivar �

6. Molecular farming of antimicrobial peptides: available platforms and strategies for improving protein biosynthesis using modified virus vectors
Abstract The constant demand for new antibiotic drugs has driven efforts by the scientific community to prospect for peptides with a broad spectrum of action. In this context, antimicrobial peptides (AMPs) have acquired great scientific importance in recent years due to their ability to possess antimicrobial and immunomodulatory activity. In the last two dec

7. Biotic Contamination and Possible Ways of Sterilization: A Review with Reference to Bamboo Micropropagation.
ABSTRACT Multipurpose use of bamboo in rural life makes it as poor man’s timber in Asian countries. Deforestation and industrialization leads to destruction of natural forest. To replenish, a rapid plantation of bamboo could be one of the possible solutions. Bamboo is propagated mainly by vegetative methods though it is not suitable for large scale plantat

8. Surface Spectroscopy of Oxisols, Entisols and Inceptisol and Relationships with Selected Soil Properties
ABSTRACT: Traditional method of soil survey is expensive, slow, and must be carried out by experienced researchers. Thus, advances in soil observation technologies and the need to obtain information quickly by modern techniques have intensified the use of proximal sensing. This study characterized surface reflectance spectra (A horizon) and related them to t

9. Caracterização bioquímica e biofísica da Celobiohidrolase II do fungo Trichoderma harzianum IOC3844 produzida por expressão homóloga / Biochemical and biophysical characterization of cellobiohydrolase II from Trichoderma harzianum IOC 3844 produced by homologous expression
The depletion of reserves, especially of refined oil , with increased energy demands and the urgent need to reduce the carbon emissions on the atmosphere, signals the necessity to search for new sources of energy renewable and clean. Concerns about global warming have led to an increased world interest in biofuels. The new concept of second generation biofue

10. Estruturas HÃbridas de Nanotubos de Carbono de Parede Simples e TelÃrio. / Single Wall Carbon Nanotubes and Tellurium Hybrid Structures
In this work we use Raman spectroscopy and electron microscopy to characterize hybrid carbon nanotube single-wall and tellurium nanostructures. Carbon nanotubes are important nanostructures due to their electrical, optical and mechanical properties, which makes them attractive for many applications in nanotechnology. However, for a wide range of applications

11. A role for adeno-associated viral vectors in gene therapy
Gene therapy constitutes a therapeutic intervention based on modification of the genetic material of living cells, by correcting genetic defects or overexpressing therapeutic proteins. The success of gene therapy protocols depends on the availability of therapeutically suitable genes, appropriate gene delivery systems and proof of safety and efficacy. Recent
