Abstract: the aim of this study was to evaluate the inclusion of an enzimatic complex in diets for nile tilapia (oreochromis niloticus) on performance, carcass chemical composition as well as water quality. the experiment was performed in 62 days. it was used two hundred reverted fingerlings (14.57 ± 1.24 g) distributed in a complete randomized design in 20 500 l-tanks with four treatments and five replicates, considering a box with 10 fish as a experimental unit. the fish were fed diets containing 0; 0.033; 0.066 and 0.099% of enzimatic complex. the diets were processed in peletized way and supplied four times a day (8:00 a.m., 11:00 a.m., 2:00 p.m. and 5:00 p.m.) the ph average values, electric conductivity, dissolved oxygen, temperature, total phosphorus, ammonia and water nitrate of the cultivation were not influenced by the inclusion of the enzimatic complexin the diet. the inclusion of enzymatic complex in the diet did not affect weight gain, survival, and specific growing rate; however, it affected diet consumption and food conversion, whose values were greater for fish fed 0.066% of enzimatic complex diet. no differences were observed on dry matter, humidity, crude protein, mineral matter, calcium and phosphorus in the fish carcass, nevertheless, the ether extract decreased linearly as the level of enzymatic complex increased. the utilization of enzimatic complex (amylase, protease, cellulase, lipase, pectinase, xylanase, β-glucanase and phytase) at the level of 0.066% for juvenile nile tilapia (oreochromis niloticus) worsens food conversion but does not influence performance and body composition of the fish.
Stress prevention by modulation of autonomic nervous system (heart rate variability): A preliminary study using transcranial direct current stimulation  [PDF]
Eduardo Manuel Gonalves
Open Journal of Psychiatry (OJPsych) , 2012, DOI: 10.4236/ojpsych.2012.22016
Abstract: Introduction: Transcranial Direct Current Stimulation (tDCS) is a non-invasive, technique for brain stimulation. Anodal stimulation causes neuronal depolarisation and long-term potentiation, while cathodal stimulation causes hyperpolarisation and long-term depression. Stressors are associated with an increase in sympathetic cardiac control, a decrease in parasympathetic control, or both. Associated with these reactions is a frequently reported increase in Low Frequency (LF) Heart Rate Variability (HRV), a decrease in High Frequency (HF) power, and/or an increase in the LF/HF ratio. Objectives and aims: The present work aims to explore the tDCS potential in the modulation of the Autonomic Nervous System (ANS), through indirect stimulation of Anterior Cingulate Cortex (ACC). Methods: Two subjects, a 39 year old female and a 49 year old male, gave informed consent. Saline soaked synthetic sponges involving two, thick, metalic (stainless steel) rectangles, with an area of 25 cm2 each have been used as electrodes, connected to Iomed Phoresor II Auto device. It has been delivered a 2 mA current, for 20 minutes, over the left Dorsolateral Prefrontal Cortex (DLPFC) (Anode). Spectrum analysis (cStress software) of HRV has been performed before and after tDCS administration. Results: The female/male subject results of LF power, HF power and LF/HF ratio, before tDCS administration, were, respectively: 50.1 nu/60 nu, 46.1 nu/21.7 nu and 1.087/2.771; and, after tDCS administration, respectively: 33.5 nu/52.7 nu, 47.6 nu/ 22.8 nu and 0.704/2.312. Conclusions: tDCS over the left DLPFC (left ACC) increased parasympathetic activity and decreased sympathetic activity, suggesting the importance of tDCS in the management of stress-related disorders.
Factorial Validation of Warr’s (1990) Well-Being Measure: A Sample Study on Police Officers  [PDF]
Sónia P. Gonalves, José Neves
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.27108
Abstract: The purpose of this study was to test the factorial validity of the job-related affective well-being scale—the IWP Multi-Affect Indicator. The sample was composed of 1466 police officers and collected through self-report questionnaires. With the objective of validating the factorial structure of the IWP Multi-Affect Indicator, several models were tested using confirmatory factor analysis. The results supported a four-factor structure: anxiety, comfort, depression and enthusiasm, as well as a five-factor structure including the same four factors plus a second-order factor called global affective well-being.

Daniel Maffasioli Gonalves, Suzi Camey
Open Journal of Psychiatry (OJPsych) , 2013, DOI: 10.4236/ojpsych.2013.31006

Objectives: This paper aims to estimate the associations between common mental disorders (CMD) as well as cases of alcohol abuse/dependence (ADD) with sociodemographic variables in population assisted by Family Health Program (FHP) in Santa Cruz do Sul, Southern Brazil. Methods: All residents over 14 years of age from 3 areas assisted by the FHP were invited to participate between 10 February 2006 to 10 February 2007. Results: Of 2921 participants, the prevalence estimates of suspected cases of CMD and ADD were 29.93% and 12.07%, respectively. Female, unfavorable employment situation, low schooling and low income showed a positive and independent association with CMD. Male, unfavorable employment situation and CMD showed an independent association with ADD. Conclusions: Groups with unfavorable socioeconomic conditions present the highest risk and should be taken into account when planning public mental health policies.

Stress, Executive Function, Resilience and Quality of Life in Portuguese Subjects in Situations of Economic Insufficiency and Unemployment  [PDF]
Eduardo Gonalves, Saul Neves de Jesus
Open Journal of Psychiatry (OJPsych) , 2015, DOI: 10.4236/ojpsych.2015.54040
Abstract: The aim of this study is the investigation of the impact of stress of Portuguese subjects in situations of economic insufficiency and unemployment on executive function and quality of life and the coping strategies and resilience skills used. The sample consists of 41 participants. The psychometric instruments used are validated for Portuguese population, measure (perceived) stress, coping, material deprivation, resilience and quality of life, defined by World Health Organization. Executive function has been evaluated through performances at Stroop and Berg tasks. It has been concluded that, in this population, resilience skills and active coping strategies are positively correlated with quality of life. Quality of life is negatively correlated with material deprivation. Active coping strategies are supported by adequate executive function, which neurobiological substrate is dorso-lateral prefrontal cortex. Not active coping strategies correlate negatively with cognitive flexibility, suggesting the presence of a deficit at infero-lateral prefrontal cortex.

Adelma do Socorro Gonalves Pimentel
Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.78110
Abstract: This essay renders concepts of psychological nutrition such as the concepts of emotional and social nourishments that guide the psychosocial integration of the human being in the world, and the concept of emotional hunger. The categories are based on some proposals from the Gestalt-therapy: dental and mental metabolisms; on assumptions from the Gestalt psychology about psychological and organic isomorphism and on the concept of theory of complexity.
Ultrasound-Guided Central Venous Catheterization: A Protocol to Be Followed in Pediatrics?  [PDF]
Mayara Gonalves Marques, Regina Grigolli Cesar
Open Journal of Pediatrics (OJPed) , 2017, DOI: 10.4236/ojped.2017.73016
Objective: To investigate the effectiveness of ultrasound-guided central venous catheterization when compared to the conventional procedure. Method: A prospective cohort study was carried out over a 9-month period from February to October 2016 involving 144 inpatients at PICU of Irmandade da Santa Casa de Sao Paulo Hospital, undergoing central venous catheterization. The patients were matched in pairs of identical patients according to the levels of potentially intervening variables (age, nutritional status, puncture site, professional experience), differing only as to the CVC technique: ultrasound-guided (USG-CVC) or conventional (C-CVC). Discarding data from non-paired patients, the remaining did forming 47 pairs, matched as two related samples: USG-CVC and C-CVC groups. Success parameters: number of puncture attempts; time spent at CVC; success rate and complications. Results: In the USG-CVC group, the number of attempts (mean = 2.04) and the time spent at catheterization (mean = 11.89 minutes) were lower (t = 2.34, df = 46, t 0.95 = 2.02, p < 0.05) and (t = 3.07, df = 46, t 0.95 = 2.02, p < 0.05), respectively, when compared to the results obtained for the control group (C-GVC), (mean = 3.21) and (mean = 28.26 minutes), respectively. As to success, there was observed a significant difference (F (1, 46) = 16.6; Q (1) = 12.5, p < 005) when considering only one trial (USG -CVC = 27/47; C-CVC = 9/47), but no significant difference (F (1, 46) = 3.76; Q (1) = 3.56, p > 0.05) when considering several attempts. Complications were found less frequently in the USG-CVC group (3/47) than in the CVC-C (13/47), (F (1, 46) = 8.24; Q (1) = 7.14, p < 0.05). Conclusion: USG-CVC was found to be more effective than the conventional technique, especially regarding success at the first puncture attempt.

Diálogos , 2010, DOI: 10.4025/dialogos.v12i2 e 3.18
Abstract: This study discusses how developmentism is approached in the speeches of the governors of Paraná State to the State Legislative Assembly and the way in which education is related to it. We begin with a brief history of the different perspectives of developmentism found in Brazilian politics from the 1950s to the 1970s. The work then moves on to developmentism in Paraná, and an analysis of the function attributed to education in the speeches of the governors and their educational policies, especially concerning the implementation of Law 5692/71, which reorganized elementary education in both elementary and high schools. Se discute cómo es abordado el desarrollismo en los Mensajes de los gobernadores del Estado de Paraná a la Asamblea Legislativa y la forma en que la Educación se relaciona con él. Se inicia con una breve historia sobre las distintas perspectivas de desarrollismo que permearon la política brasile a entre las décadas de 1950 y 1970. Luego es abordado el desarrollismo en el Estado de Paraná, analizando el papel atribuido a la Educación en los discursos de los gobernadores y en las políticas educacionales, en especial, las referentes a la implementación de la Ley 5.692/71, que reorganizaba la ense anza básica primaria y secundaria. Discute-se como o desenvolvimentismo é abordado nas mensagens dos governadores do Estado do Paraná à Assembleia Legislativa do Estado e a maneira como a Educa o é a ele relacionada.
