1. Crop residue harvest for bioenergy production and its implications on soil functioning and plant growth: A review
ABSTRACT: The use of crop residues as a bioenergy feedstock is considered a potential strategy to mitigate greenhouse gas (GHG) emissions. However, indiscriminate harvesting of crop residues can induce deleterious effects on soil functioning, plant growth and other ecosystem services. Here, we have summarized the information available in the literature to id

2. How does the nectar of stomata-free nectaries cross the cuticle?
ABSTRACT In many glandular structures, departure from the cell is only one step in the process of exudate release to the plant surface. Here the set of events that lead nectar to the external environment is presented and discussed mainly for stomata-free nectaries. After being synthesized, the nectar or some of its component needs to be released to the envir

3. Overcoming crossing barriers between jatropha (Jatropha curcas L.) and castor bean (Ricinus communisL.)
Abstract A limitation in improvement of jatropha (Jatropha curcas) has been the low genetic variation among the available germplasm. An alternative to create genetic variability and incorporate desirable traits is through wide crossing. Due to reproductive barriers, wide crossing in jatropha has had limited success. In this experiment, intergeneric hybridiza

4. Root Distribution of Peach Rootstocks Affected by Soil Compaction and Acidity
ABSTRACT Root growth can be limited by physical and chemical conditions of the soil. Compacted and acidic soils, where there is an occurrence of exchangeable Al, constitute barriers to use of the soil by plant roots. The hypothesis of this study was that physical and chemical properties of the inter-row soil of a peach orchard influence the root distribution

5. PLANTWIDE PERIODICAL DISTURBANCES ISOLATION AND ELIMINATION IN A PETROCHEMICAL UNIT
Abstract Reducing process variability is crucial to reach a more profitable operating point. Periodical disturbances, however, impose barriers to achieve this goal. Their effect can be strong since one disturbance that appears in a specific loop of a highly coupled plant can be seen in several loops. Thus, isolating their source and diagnosing their cause ar

6. Temporal Geobiotic Mapping: a conceptual mapping technique toward visualising geobiotic areas in cross-section
Geobiota are defined by taxic assemblages (i.e., biota) and their defining abiotic breaks, which are mapped in cross-section to reveal past and future biotic boundaries. We term this conceptual approach Temporal Geobiotic Mapping (TGM) and offer it as a conceptual approach for biogeography. TGM is based on geological cross-sectioning, which creates maps base

7. A evolução da qualidade das águas do rio Paraíba do Sul / The evolution of water quality in the Paraiba do Sul River
There are a number of uses that involve the water consumption that are direct consequences of the industrialization and urbanization intensive process, as well as population growth. The sewage treatment plants serve as environmental barriers increasing the multiple uses of water. This improvement in water quality reduces the risk of spreading diseases to the

8. Uso de leguminosas arbóreas no controle da evolução de voçoroca no domínio do cerrado
Este trabalho foi desenvolvido na estação experimental da Fazenda do Glória, em Uberlândia- MG. O objetivo foi avaliar o uso de formas alternativas, de baixo custo, para a recuperação de voçorocas com revegetação e barreiras vegetais. Voçoroca é o estágio mais avançado dos processos de erosão e a sua recuperação é um desafio, principalmente

9. Clonagem e estudos de expressão de enzimas do fungo filamentoso Trichoderma harzianum IOC-3844 envolvidas na degradação de biomassa
The plant biomass is a large-scale available resource and one of its more important applications is the second-generation ethanol production. However, the enzyme cost is one of the biggest barriers for economically viable ethanol from biomass. Therefore, it is important to identify fungal strains that can produce high concentrations of plant biomass-degradin

10. Downstream passage of fish larvae and eggs through a small-sized reservoir, Mucuri river, Brazil
In South America, one important symptom of the failure of fish passages to sustain fish migratory recruitment is the inability of eggs and larvae to reach the nurseries. This is especially so when the breeding areas are located upstream of a reservoir, and the floodplain is downstream of the dam. Therefore, the transport of fish larvae and eggs across reserv

11. Modelagem matemática na previsão de colheita de bananeira: regressão linear múltipla x redes neurais artificiais / Mathematical modeling to predict crop of banana: multiple regression x neural networks
One of the barriers relevant to the banana crop in Brazil is the lack of productive commercial varieties with adequate size, resistant to major pests and diseases and adapted to different ecosystems. The development of cultivars is the strategy for solving this problem through breeding programs, as well as its characterization and evaluation in areas of prod

12. Dormencia em sementes de arroz vermelho / Dormancy in seeds of red rice
O arroz vermelho é considerado a principal planta daninha na maioria das lavouras de arroz, pois, além dos prejuízos causados pela competição, sua similaridade com o arroz cultivado dificulta seu controle. A dormência e a viabilidade de suas sementes no solo permitem a continuidade dos biotipos na lavoura e facilitam a disseminação para áreas próxi
