The Environmental Management System of ISO 14001 stands out as one of the most widely used systems for managing corporate environmental aspects and processes and the Cleaner Production is a proactive ...environmental strategy that has remarkably positive results in environmental corporate management. The principal aim of this article was to identify and analyze the influence relations of the ISO 14001 Environmental Management System to the Cleaner Production through a survey-based research. The maturity and the phases of planning and discipline are key factors for the systematization and continuity of Cleaner Production practices. The stages of Planning, Evaluation and Feasibility Study, and Implementation were identified as the main stages of CP fostered by the ISO 14001 Environmental Management System.
•We analyzed the relations of the ISO 14001 EMS to the CP in industrial companies.•The main influence relations were identified and discussed.•Four hypotheses of relations were tested.•Two main CP stages are fostering by the ISO 14001 EMS.•These results should be considered in many industrial sectors worldwide.
Regeneration is a widely spread process across the animal kingdom, including many species of marine crustaceans. It is strongly linked to hormonal cycles and, therefore, a great endpoint candidate ...for toxicology studies. We selected the amphipod
Parhyale hawaiensis
as test organism, already used in ecotoxicological studies and able to regenerate its body appendages. We are proposing a protocol to use the antenna regeneration as a toxicity endpoint. First, we evaluated differences in time of completion of regeneration in males and females after the amputation of one antenna of 6 months old animals. Then we compared the influence of different testing volumes in the regeneration process (100 and 5 mL). We used as testing substances, dimethyl sulfoxide (DMSO) and diflubenzuron, a chitin synthesis inhibitor. The most suitable protocol consisted of volumes of 5 mL in 12-well microplates, with 1 organism per well, 12 organisms per concentration (1:1 females/males) and test time duration of around 5 weeks. DMSO accelerated regeneration time with a NOEC of 0.06%. Diflubenzuron inhibited the time necessary to its completion with a NOEC of 0.32 μg L

. We conclude that the
Parhyale hawaiensis
antenna regeneration protocol proposed here is a potential tool in ecotoxicology, but more studies are required for its validation not only to verify its utility for testing chemicals but also environmental samples.
•LCA is a key tool in selecting CCS/CCU technologies.•LCA of CCS/CCU technologies might assist in finding suitable decarbonization technologies.•LCA can reveal the potential of chemical industries ...for using CCU technologies.•Integrated techniques can provide a broader assessment of CCS/CCU technologies.
The need to reduce greenhouse gas emissions and tackle climate change has mobilized the whole world towards finding technologies and creating public policies aimed at a decarbonization of different sectors of the economy. Carbon capture and storage/utilization (CCS/CCU) technologies can ease the transition to renewable energy so as to meet the growing energy consumption demand estimated for the next 30 years. However, the environmental benefits gained by these emerging technologies must be critically evaluated, and the life cycle assessment (LCA) has been widely and successfully applied for such a purpose. Thereby, this paper provides an overview of the LCA of CCS/CCU technologies found in literature through a comprehensive bibliometric analysis of publications from 1995 through 2018 in order to highlight the current state and future challenges. The main authors, countries, institutions and research areas that apply LCA of CCS/CCU technologies have been identified through analyzing performance indicators using science mapping software tools. Analyzes have revealed that, driven by climate change mitigation targets, a widespread application of the LCA has addressed different CCS/CCU technologies focused not only on fossil energy generation (electricity and fuels), but also upon renewable energy and industrial processes (mainly in the production of cement and chemicals such as methanol). Scientific gaps have also been identified with the aim of promoting and guiding new studies on the matter at hand. These gaps demonstrate the need to collect primary data for different processes and technologies associated with CCS/CCU and conduct more thorough LCA studies and integrated assessments applied to CCS/CCU technologies. Therefore, the main contribution of this paper is to highlight their evolution and assist new studies on the LCA of CCU/CCS technologies by seeking improvement in this field of research.
To survive in the long term, business needs to profit, controlling environmental impacts with social responsibility. Sustainability programs involve the integration of social and environmental issues ...in business models and organizational processes. The assessment of sustainability programs is a problem of multiple criteria decision analysis (MCDA). This work presents applications of MCDA for the assessment of sustainability programs in the textile industry. Applied methods for MCDA are analytic hierarchy process (AHP) and the technique for the order of preference by similarity to ideal solution (TOPSIS). The reasons to apply AHP and TOPSIS include providing an assessment index, ranging from 0 to 1, and that the MCDA model is expected to have more criteria than alternatives. Therefore, an application of other methods, such as data envelopment analysis, could be prejudiced. Concepts from the triple bottom line, economic, social as well as environmental criteria were inserted in the proposed model. Sustainability programs of six leading companies from the Brazilian textile industry were evaluated. The main finding of the research is that AHP and TOPSIS resulted in similar evaluations for sustainability programs. Both methods resulted in the same rank of alternatives. However, with TOPSIS, companies' sustainability indices were more disperse, varying from 0.10 to 0.92 against a range from 0.23 to 0.69 with AHP.
The bipartite begomoviruses (Geminiviridae family), which are DNA viruses that replicate in the nucleus of infected cells, encode the nuclear shuttle protein (NSP) to facilitate the translocation of ...viral DNA from the nucleus to the cytoplasm via nuclear pores. This intracellular trafficking of NSP–DNA complexes is accessorized by the NSP-interacting guanosine triphosphatase (NIG) at the cytosolic side. Here, we report the nuclear redistribution of NIG by AtWWP1, a WW domain-containing protein that forms immune nuclear bodies (NBs) against begomoviruses. We demonstrated that AtWWP1 relocates NIG from the cytoplasm to the nucleus where it is confined to AtWWP1-NBs, suggesting that the NIG-AtWWP1 interaction may interfere with the NIG pro-viral function associated with its cytosolic localization. Consistent with this assumption, loss of AtWWP1 function cuased plants more susceptible to begomovirus infection, whereas overexpression of AtWWP1 enhanced plant resistance to begomovirus. Furthermore, we found that a mutant version of AtWWP1 defective for NB formation was no longer capable of interacting with and relocating NIG to the nucleus and lost its immune function against begomovirus. The antiviral function of AtWWP1-NBs, however, could be antagonized by viral infection that induced either the disruption or a decrease in the number of AtWWP1-NBs. Collectively, these results led us to propose that AtWWP1 organizes nuclear structures into nuclear foci, which provide intrinsic immunity against begomovirus infection.
A WW domain-containing protein, AtWWP1, forms dynamic nuclear bodies (NBs) and redirects NIG, a viral DNA nucleocytoplasmic transport facilitator, from the cytosol into the immune NBs, which are counteracted by viral DNA

ABSTRACT Insecticide spray drift can lead to reduced control efficiency and loss of product to the environment. Thus, we conducted a study to evaluate the effect of different spray nozzles and the ...addition of adjuvants in insecticide spray on the resulting droplet spectrum and wind tunnel drift. All experiments were conducted in a completely randomized design with four repetitions using a 5 × 3 factorial scheme. Five spraying solutions were studied; one contained only water and the other four comprised thiamethoxam + lambda-cyhalothrin (no adjuvant, Oro-solve, Wetcit Gold, and Orobor N1), in combination with three spray nozzles (AXI, JFC, and J3D). The droplet spectrum was evaluated through the volumetric median diameter, relative amplitude, and percentage of the droplet volume with diameter ≤ 100 µm. The drifts were evaluated in a wind tunnel at 5, 10, and 15 m. Data were subjected to analysis of variance and means were compared using the Tukey’s test. In addition, a principal component analysis was performed. Application of the insecticide with the adjuvants combined with the different nozzles changed the droplet spectrum and the risk of drift. The AXI nozzle and the J3D associated with the Oro-solve and Wetcit Gold adjuvants resulted in a greater volumetric median diameter of the droplets and drifts were observed at 5 m.
RESUMO A deriva da pulverização de inseticidas pode proporcionar a redução da eficiência de controle e perda para o ambiente. Desta forma, foi conduzido um estudo com o objetivo de estudar o efeito de diferentes pontas de pulverização e adição de adjuvantes na calda inseticida, em relação ao espectro de gotas e deriva em túnel de vento. Os experimentos foram conduzidos no delineamento inteiramente casualizado, com quatro repetições, no esquema fatorial 5 × 3, constituído por cinco caldas, uma apenas com água e outras quatro com inseticida tiametoxam + lambda-cialotrina (sem adjuvante, Oro-solve, Wetcit Gold e Orobor N1), combinadas com três pontas de pulverização (AXI, JFC e J3D). Foi avaliado o espectro das gotas, através do diâmetro mediano volumétrico, amplitude relativa e porcentagem do volume de gotas com diâmetro ≤ 100 µm. A deriva foi avaliada em túnel de vento, a diferentes distâncias: 5, 10 e 15 m. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey. Além disso, foram realizadas análises de componentes principais. A aplicação do inseticida com os adjuvantes combinados com as diferentes pontas de pulverização alterou o espectro de gotas e o risco da deriva. A ponta AXI e a J3D associada aos adjuvantes Oro-solve e Wetcit Gold apresentaram maiores diâmetros medianos volumétricos das gotas e deriva a 5 m.

Conference Proceeding
Bismuth triiodide (BiI3) is a possible candidate to replace lead in perovskite-like materials for photovoltaic applications. Besides this applicability as an active layer in solar cells, BiI3 can ...also be converted, using methylammonium iodide, to the perovskite-like material MA3Bi2I9, that is also suitable for photovoltaic applications. Here we investigate the thermal stability of thermally evaporated BiI3 thin films annealead up to 150 °C in ambient atmosphere (in a closed oven in the absence of illumination). BiI3 films show similar X-ray diffratrograms with indexed peaks related to an R-3 rhombohedral crystal structure. The bandgaps of BiI3 thin films were determined by Tauc plots of transmittance data in UV-vis range and indicate a bandgap of 1.72 eV regardless of annealing temperature and suitable for photovoltaic applications. We verified that its morphological properties, observed through SEM images, are also not changed with respect to its annealing at temperatures up to 150 °C. Thereby, the structural, morphological and optical properties of annealing on thermally evaporated BiI3 are not considerably altered, the films retaining their properties when heated up to 150 °C, temperature higher than the operation temperature of solar cells and below the melting point of BiI3.
