Degradação fotoquímica de efluentes industriais contendo polipropileno e isoniazida

One of the main impacts to the environment is the water pollution, where the industrial sector is one of the main sources of this problem. In order to search for a solution, the industrial sector is looking forward to new technologies to treat its wastewaters with the goal to reuse the water in the own process. In this mode, the treatment presents a reduction in its costs with the water suply. One of these technologies that are getting more and more applications is the advanced oxidative processes (AOP´s). In this work two industrial wastewaters have been studied, i.e., containing polymers and pharmacus. In the case of the wastewaters with polymers the UV/H2O2 process has been applied with a systematic series of experiments, using irradiation from a mercury lamp and also solar. The following variables of the UV/H2O2 process for the polymers wastewaters have been studied systematically with the lamp reactor: mode of addition of hydrogen peroxide, temperature, time of reaction, hydrogen peroxide concentration and power of the lamp (80, 125, 250 and 400W). The results demonstrated to be satisfactory, obtaining rates of organic charge removal of 100% in 120 minutes of reaction. The studied variables for the experiments with solar irradiation using polymers wastewaters were only the time of reaction, the mode of addition and concentration of the hydrogen peroxide. The results with the solar irradiation demonstrated to be not satisfactory, reaching maximum of 22% of TOC removal in 240 minutes of reaction. This is in accordance with the fact that the solar source has only 5% of low UV irradiation. With respect to the photodegradation of the pharmacus wastewaters, the process UV/H2O2 and photo-Fenton have been applied. As a source of photons, in this case, a mercury UV lamp of 80 W has been used. The studied variables for the experiments with artificial irradiation with the pharmacus wastewaters were: initial concentration of the pollutant, concentration of Fe2+ and time of reaction. The results demonstrated a degree of degradation fairly satisfactory, showing a maximum conversion value of 46% in 120 minutes

Cosmoeducação: uma abordagem transdisciplinar no ensino de astronomia

This work proposes a transdisciplinary approach that integrates transpersonal psychology exercises with astronomy teaching, seeking to allow one to reintegrate the sky in his/her daily life, expand his/her environmental awareness and eventually experiment the unity between human and cosmos. This proposal intends to collaborate with the supplying of education, which lacks initiatives of this kind, with the promotion of an integration of the scientific knowledge with the human experience that transcends the materialistic and fragmentary objectives of the current educational system. As a result of that lack, the teachers formation is also poor as for an integral and transdisciplinary approach. Besides, we also approached in this research the necessity to propose alternatives so that the educators may work in a more assertive way with the environmental and anthropological crisis in which we are living. Our working hypothesis is that the contents of astronomy, when they are dealt in a holisticanthropological focus and are related with transpersonal psychology practices, can come to be an efficient cultural-academic vehicle, capable of propitiating an expansion of consciousness and changes in the way one conceives the world. Such changes are necessary so that a more solidary, fair and ecologically balanced life may come to exist and prevail in the planet. Part of the collection of data was done through the ethnographic method, once an anthropological interpretation is inextricably associated with this kind of educational intervention, which will naturally include ethno-visions of the universe as well as specific cultural elements. In the beginning the scope of this research was a group of students attending the Astronomy assignment in an undergraduate Geography course (UFRN), in which we accomplished participant observation, half-open interviews and the first experimental practices mentioned. After the evaluation of the first data collected from that initial group, we elaborated an academic extension course, Laboratory in Cosmoeducation, and we offered it to teachers of the 1st and 2nd cycles of the fundamental level of the Alceu Amoroso Lima State School, located in the North Zone of Natal. We prized self-experimentation in that course, so that the teachers could enrich their repertoire of personal experiences, stimulating meditative reflections and eventual changes in the ways of conceiving the world and in their pedagogical practice. The transdisciplinary attitude permeated all our educational action, because this approach transcends the boundaries of disciplines, seeking essentially the integral development of the human being. The process has made us realize that the practice of looking at the sky , as a way of reintegrating it into daily life, provokes a process of expansion of the consciousness and of reintegration of the self in a wider level of environmental interrelation. According to the results, the occurrence of conceptual and existential changes of the world vision of the participant teachers was evident, reassuring ourselves of the idea that the interface between astronomy teaching and the practices of transpersonal psychology can contribute to the recovery of a holistic relationship between the human being and the cosmos and to inspire the arising of a more wide-ranging ethics, based on universal, impartial and sustainable values

Qualidade de vida de pessoas com estomias intestinais

Ostomy is an open surgical origin, when it is necessary to deviate temporarily or permanently, the normal transit of food and / or deletions. The patient with ostomy disposal is faced with changes in their physiology, also emerging on the need to care collection bag. This study aimed to analyze the quality of life (QOL) of people living with ostomy Intestinal (EI), who attended the Pediatric and Adult Rehabilitation Center of Rio Grande do Norte (CRI / CRA-RN). It is an analytical study with cross-sectional design and quantitative approach, accomplished with 89 people who had EI. The study was approved by the Ethics Committee of the Federal University of Rio Grande do Norte (CEP / UFRN), CAAE: 19866413.3.0000.5537. Held data collection in the period January-March 2015 using two instruments: an adapted general questionnaire covering socio-demographic, clinical and self-care and a specific instrument for assessing QOL of people with stoma titled as City of Hope Quality of Life - Ostomy Questionnaire (COH-QOL-Q), validated and adapted to Portuguese in 2010, composed of four areas, namely: Welfare Body (BEF), Welfare Psychological (BEP), Welfare (BES ) and Spiritual Well-Being (BEE). The collected data were entered into a database in Microsoft Excel 2007 spreadsheet application and processed in computerized software for descriptive and inferential analysis. The results showed that 83.1% had a colostomy and ileostomy 16.9%. Sociodemographic characteristics prevailed in males (57.3%), over 50 (57.3%), mulatto (46.1%), with presence of companion / a (57.3%), retired / beneficiaries (50.5%), monthly income above the minimum wage (68.5%) and who have studied up to elementary school (67.4%). Regarding clinical aspects, it was observed that the main cause that led to the making of the stoma was the neoplasm (59.6%) followed by trauma (21.3%). The sample showed people with stoma for more than six months (79.8%) of permanently (57.3%), in use sink equipment piece drainable (68.5%) of flat base (82.0%). With respect to self-care, 93.3% emptied and washed the bag alone (care related to hygiene) and 75.3% fixed the new exchange on the skin during the exchange (care related to the stock). Patients with more than six months of ostomy and had no partner (a) had higher averages of self-care related hygiene and purse. The average of respondents QoL scores was 68.90% for General QOL; 68.03% for the BEF; 68.38% for the BEP; 66.46% for BES and 75.41% for BEE. Among the aspects that influenced QOL included: physical strength, pain, suffering and gases (physical domain); appearance, care of the stoma and adaptation to new condition (psychological domain); isolation, interference in personal relationships and social activities (social domain) and going to church or synagogue, spiritual activities and positive change after ostomy (spiritual realm). Based on these results, it is concluded that this was a predominantly adult sample / elderly (between 50 and 70 years), with low education and the cause motivating the stoma, neoplasms. However, such findings did not pass at low percentage levels on the self-care capacity to deliver even at low QOL scores.
