Metabolic and Behavior Changes in Surubim Acutely Exposed to a Glyphosate-Based Herbicide

This study examined the effect of glyphosate-based herbicide (Roundup Original), the major herbicide used in soybean crops in Mato Grosso state, at concentrations of 0, 2.25, 4.5, 7.5, and 15 mg L-1 on metabolic and behavior parameters of the hybrid fish surubim in an acute exposure lasting 96 h. Glycogen content, glucose, lactate, and protein levels were measured in different tissues. Plasma levels of cholesterol, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were also determined. Ventilatory frequency (VF) and swimming activity (SA) were considered behavior parameters. Results showed that herbicide exposure decreased plasma glucose levels and increased it in surubim liver. Lactate increased in both plasma and liver but decreased in muscle. Protein levels decreased in plasma and muscle but increased in liver. After herbicide exposure, liver and muscle glycogen was decreased. Cholesterol levels decreased in plasma at all concentrations tested. Plasma ALT increased, and no alterations were recorded for AST levels. VF increased after glyphosate exposure (5 min) and decreased after 96 h. SA showed differences among all groups (5 min). At the end of 96 h, SA was altered by the 7.5 mg L-1 concentration. Fish used anaerobic glycolysis as indicated by generally decreased glycogen levels and decreased lactate levels in muscle but increased ones in plasma and liver. We suggest that the studied parameters could be used as indicators of herbicide toxicity in surubim and may provide extremely important information for understanding the biology of the animal and its responsiveness to external stimuli (stressors).

A expansão do setor sucroenergético no estado de São Paulo

The changes occurring in Brazilian agriculture, with the inclusion of agro-industrial activities in your mode of production, must be analyzed to verify the changes in the behavior of territorial dynamics. Through changing the Rural Complex, traditional for the Agroindustrial Complex tightly integrated with trade and industry brought many consequences for the rural population, with regard to employment. Understanding this transformation capitalist the field is needed to analyze the actors involved in this process and the policies adopted for the expansion of sugar and ethanol activity in the State of São Paulo and the consequences for the spatial organization. The expansion of cane production areas were governed by the Institute of Sugar and Alcohol (IAA), the National Alcohol Program (PROÁLCOOL) Development Plan for the West of São Paulo - PRO-WEST and Expansion Program for the production of Canavicultura for production of fuel for the State of São Paulo (PROCANA). The occupation of these agroindustrial facilities in rural spaces contextualized by territorialization of the rural complex, in that sense, understanding these concepts is a key part development in the research. therefore, are concepts of fundamental importance to geographical science, and interpreting their function and construction in rural spaces

Understanding the genesis of green supply chain management: lessons from leading Brazilian companies

This work discusses the internal structuring processes of leading companies when adopting green supply chain management (GSCM) practices. A multiple case study approach was adopted as the research methodology, with four large Brazilian companies that are leaders in their market segments. The introduction of green products is a key step towards initiating concern for the environment among suppliers and customers. This study's results show the importance of having green teams, a dedicated functional area, and/or green jobs that support the discussion of environmental management among a business and beyond. The practical results of this study offer new insights into the behavior of companies that are adopting GSCM practices, thereby generating new evidence for the extension of GSCM theory.

Anelastic behavior due to interstitial oxygen in SmBa(2)Cu(3)O7-delta

The composite SmBa2Cu3O7-delta (Sm-123), obtained by the substitution of the ion Y for Sm in the very well known and studied YBa2Cu3O7-delta (Y-123), is potentially attractive for better understanding superconductivity mechanisms and for its applications as electronic devices. Sm-123 samples show higher critical temperatures than Y-123 ones do and a larger solubility of Sm in Ba-Cu-O solvent, which makes their growth process faster. When oxygen is present interstitially, it strongly affects the physical properties of the material. The dynamics of oxygen can be investigated by anelastic spectroscopy measurements, a powerful technique for the precise determination of the oscillation frequency and the internal friction when atomic jumps are possible. Anelastic spectroscopy allows determining the elasticity modulus (related to the oscillation frequency) and the elastic energy loss (related to the internal friction) as a function of the temperature. The sample was also investigated by X-ray diffraction (XRD), scanning electronic microscopy (SEM), and electric resistivity. The results obtained show a thermally activated relaxation structure composed by at least 3 relaxation processes. These processes may be attributed to the jumps of oxygen atoms present of the Cu-O plane in the orthorhombic phase.

Compensatory Health Beliefs Predict Maladaptive Coping, Impulsivity, and Erroneous Health Perceptions

Compensatory Health Beliefs (CHB) are a common strategy used to reduce the cognitive discomfort that arises from participating in recognizably unhealthy behaviors. The current research examines relationships between CHB and other cognitive variables. Data was collected in two phases, using survey methodology. Study 1 explored relationships between the use of CHB, impulsiveness, and coping styles. Study 2 expanded the inquiry by exploring relationships to health perception and knowledge. Results revealed that participants who scored high on overall CHB were more likely to: engage in maladaptive coping strategies (r = .47, p < .01) [including avoidant coping styles (r = .38, p < .01) and unhealthy coping styles (r = .47, p < .01)], score higher on measures of impulsivity (r = .43, p < .01), be well-informed about their general health (r =-.21, p < .05), eat fast food more often ( r = p < .05), and consider it safe to smoke more frequently (r = .18, p < .05). Participants with lower CHB scores considered themselves more well-informed about their general health (r = -.21, p < .05), including understanding the minimum recommended amounts of physical activity needed to maintain health (r = -.35, p < .01 ), and knowing the health risks of stress ( r = -.19, p < .05). In addition, maladaptive coping was positively correlated with lack of general health knowledge (r = -.22 p < .01), less understanding of the risks of stress and alcohol (r = .20, p < .05), less knowledge of the recommended daily amounts of physical activity needed for health (r = -.26, p < .01), less frequent exercise (r = -.26, p < .01 ), and generally more unhealthy daily habits (r = -.26, p < .01). These findings contribute to a new area of investigation and may be useful to those who want to motivate behavior change.

Improving Student Engagement and Verbal Behavior Through Cooperative Learning

In this action research study of my classroom of 10th grade Algebra II students, I investigated three related areas. First, I looked at how heterogeneous cooperative groups, where students in the group are responsible to present material, increase the number of students on task and the time on task when compared to individual practice. I noticed that their time on task might have been about the same, but they were communicating with each other mathematically. The second area I examined was the effect heterogeneous cooperative groups had on the teacher’s and the students’ verbal and nonverbal problem solving skills and understanding when compared to individual practice. At the end of the action research, students were questioning each other, and the instructor was answering questions only when the entire group had a question. The third area of data collection focused on what effect heterogeneous cooperative groups had on students’ listening skills when compared to individual practice. In the research I implemented individual quizzes and individual presentations. Both of these had a positive effect on listing in the groups. As a result of this research, I plan to continue implementing the round robin style of in- class practice with heterogeneous grouping and randomly selected individual presentations. For individual accountability I will continue the practice of individual quizzes one to two times a week.
