1. Straw removal of sugarcane from soil and its impacts on yield and industrial quality ratoons
ABSTRACT: Mechanical harvesting leaves in its wake a considerable amount of straw in the field, which can be effectively utilized to improve the soil condition and sugarcane yield. However, there is no specific information as to the quantity of straw mulch required to achieve such effects and as to whether it can be used in other sectors for bioelectricity a

2. Análise da aplicação da biomassa da cana como fonte de energia elétrica: usina de açúcar, etanol e bioeletricidade. / Analysis of application of sugarcane biomass as a source of electricity: sugar mill, ethanol and bioelectricity.
Apresenta-se neste trabalho a aplicação de turbogeradores instalados em usinas de açúcar e etanol como alternativa eficiente de complementaridade do sistema energético brasileiro e contribuição à utilização de recursos renováveis, além de fazer abordagem aos sistemas de cogeração para este tipo de aplicação. A biomassa da cana-de-açúcar dis

3. Potencialidade da célula combustível microbiana para geração de energia elétrica a partir de esgoto sanitário / Potential microbial fuel cell to generate electricity from wastewater
O presente projeto avaliou uma célula combustível microbiana (CCM) composta de um reator combinado (anaeróbio e aeróbio), operada em fluxo contínuo com tempo de detenção hidráulico de 12 horas, alimentada com esgoto sintético (487 + OU -115 mg DQO/L) e esgoto sanitário (631 + OU -213 mg DQO/L). A estabilidade da CCM variou conforme as característi

4. Comercialização de bioeletricidade no ambiente de contratação livre pelas usinas do setor sucroenergético da região de Ribeirão Preto: panorama e análise das ameaças e oportunidades / Comercialitation of bioelectricity in the free contracting environment by the sugar cane mills of the sugar-energy sector from the region of Ribeirão Preto: scenery and analysis of opportunities e threats
In recent years, the Brazilian electricity market has gone through provision crises, due to the greater increase in demand with regard to supplies. Resulting from the lack of infrastructural investments and the concentration of the energy matrix in hydroelectricity, this scenario can be minimized by the bioelectricity coproduced based on sugar cane pulp. How

5. Projeto de biodigestor para geração de bioenergia em sistema de produção de suínos: um estudo de caso da região de Icolo e Bengo - Angola / Bio digester project for bioenergy generation in swine production system: a case study for the region of Icolo e Bengo - Angola
A tecnologia da biodigestão anaeróbia tem sido comprovada como uma das mais eficientes no tratamento dos dejetos de suínos, esta tecnologia, encontra-se num crescimento tímido em Angola facilitando assim uma poluição maior dos Rios, solos e o ar atmosférico, por falta de tratamento adequado da biomassa produzida por milhares de suínos existentes nest

7. Transduction of chemical into electrical energy.
The paper recalls some fundamental notions, developed by Otto Meyerhof, which were used in the analysis of the transduction of chemical into mechanical energy during muscular contraction. These notions formed the basis of the approach to the analysis of the transduction of chemical into electrical energy, i.e., the very principle underlying nerve and muscle

8. Bioelectricity and regeneration: large currents leave the stumps of regenerating newt limbs.
Electrical currents near regenerating newt limbs were measured with a recently developed vibrating probe. Steady currents with local surface densities of 10 to 100 muA/cm2 or more leave the end of the stump during the first 5-10 days after amputation and are balanced by currents with densities of only 1-3 muA/cm2 that enter the intact skin around the stump.

9. PHOTOREGULATION OF BIOLOGICAL ACTIVITY BY PHOTOCHROMIC REAGENTS, III. PHOTOREGULATION OF BIOELECTRICITY BY ACETYLCHOLINE RECEPTOR INHIBITORS*
The photochromic compounds N-p-phenylazophenyl-N-phenylcarbamylcholine chloride and p-phenylazophenyltrimethylammonium chloride inhibit the carbamylcholine-produced depolarization of the excitable membrane of the monocellular electroplax preparation of Electrophorus. The trans isomer of each predominates in the light of a photoflood (420 mμ) lamp; they are

10. Chemical Events in Conducting and Synaptic Membrances during Electrical Activity
Evidence has accumulated in recent years for the central role of proteins and enzymes in the function of cell membranes. In the chemical theory proposed for the generation of bioelectricity, i.e., for the control of the ion permeability changes of excitable membranes, the protein assembly associated with the action of acetylcholine plays an essential role.

11. Dynamic properties of isolated acetylcholine receptor proteins: release of calcium ions caused by acetylcholine binding.
Interaction of Ca and acetylcholine (AcCh) ions with purified acetylcholine receptor (AcChR) from Torpedo californica and Electrophorus electricus has been investigated in view of these ions' role proposed in bioelectricity. Spectrophotometric Ca titration using murexide as an indicator and an ultrafiltration method with 45Ca show that AcChR proteins have a
