Cellulose is the most abundant vegetable organic compound, being derived mainly from plant residues. The decomposition of sugar-cane (Saccharum officinarum L.) straw was studied in a period up to 90 days, through variables related to the carbon cycle, such as respiratory activity and CM-cellulase (CM, cellulose microcrystalline) and CMC-cellulase (CMC, carboxymethylcellulose) activities. The treatments consisted of 0, 0.5 and 1.0% of straw, in the presence and absence of vinasse (a sugar-cane alcohol industry byproduct) and nitrogen fertilizer. The respiratory and cellulase activities increased up to the 14th day of incubation and later decreased. The respiratory activity was 1.9 and 2.3 fold larger (P < 0.05) in the soil with 0.5 and 1.0% of straw added, respectively, in relation to the control. CM- and CMC- cellulase activities also increased from 1.8 to 2.9 and from 2.3 to 2.7 fold, respectively. The vinasse addition enhanced CO 2 production and CM-cellulase activity, however, no significant effect was observed on CMC-cellulase activity. The addition of N reduced both respiratory and cellulase activities. The decomposition of the sugar-cane straw may enhance soil nutrient cycling increasing agricultural production. © 2006 Instituto de Investigaciones Agropecuarias, INIA.

Introduction: The current Brazilian legislation states that health services must be performed by the Specialized Service of Safety Engineering and Labor Medicine (SESMT). Objective: To analyze the dental and medical reasons for absenteeism, checking the interference of factors such as age, gender and position of the worker, and most of the reasons that led the employee to miss work. Material and methods: The research appears as a descriptive study with a quantitative approach. The dental and medical certificates and statements of attendance were analyzed, duly approved, lodged in a acrylic industry in the city of Araçatuba-SP, from January to July 2011. Results: Of the total number of certificates (n = 1841), only 103 (5.6%) were for dental reasons. Predominance of the age group of 20-29 years, males and with non-administrative function. The reasons most dental and medical certificates stated that led the workers to miss working days were "inclusive and impacted teeth" and "diarrhea and gastroenteritis of presumed infectious origin", respectively. As to factors related to absenteeism, there was a severity index of 2.83, 1.33 frequency and average duration of absences of 2.12. Conclusions: It is concluded that dental reasons had little weight on total absences due to illness that caused the temporary leave of the worker for a shorter period. The age and function variables influence the occurrence of work absenteeism.

JUSTIFICATIVA E OBJETIVOS: Nos últimos anos o número de novos usuários de agentes ilícitos tem aumentado de forma significativa em todo o mundo. A maconha e a cocaína, além do álcool e do tabaco, têm sido os agentes citados com freqüência, porém houve um aumento significativo de usuários de outros agentes psicoestimulantes ou alucinógenos, como o Ecstasy, o GHB, o LSD e a metanfetamina, empregados com o objetivo de intensificar as experiências sociais. O objetivo do presente artigo foi discutir a apresentação clínica, os efeitos deletérios e as potenciais interações com o ato anestésico no paciente cirúrgico usuário desses agentes ilícitos. CONTEÚDO: O artigo discute os mecanismos de ação, a apresentação clínica, os efeitos deletérios e as possíveis repercussões observadas durante a anestesia no usuário de MDMA (3,4-metilenodioximetanfetamina), também conhecido como Ecstasy. CONCLUSÕES: A apresentação clínica e os efeitos deletérios provocados pelo 3,4-metilenodioximetanfetamina (Ecstasy), assim como potenciais interações com o ato anestésico devem ser do conhecimento do anestesiologista, pois em muitas situações esses usuários serão submetidos a intervenções cirúrgicas de emergência, ou mesmo eletivas.

OBJETIVO: Estimar a prevalência e fatores associados à doença pulmonar obstrutiva crônica. MÉTODOS: Estudo transversal, de base populacional com 1.441 indivíduos de ambos os sexos e com 40 anos de idade ou mais no município de São Paulo, SP, entre 2008 e 2009. As informações foram coletadas por meio de entrevistas domiciliares e os participantes foram selecionados a partir de amostragem probabilística, estratificada por sexo e idade, e por conglomerados em dois estágios (setores censitários e domicílios). Foi realizada regressão múltipla de Poisson na análise ajustada. RESULTADOS: Dos entrevistados, 4,2% (IC95% 3,1;5,4) referiram doença pulmonar obstrutiva crônica. Após análise ajustada, identificaram-se os seguintes fatores independentemente associados ao agravo: número de cigarros fumados na vida (> 1.500/nenhum) RP = 3,85 (IC95%: 1,87;7,94), cansar-se com facilidade (sim/não) RP = 2,61 (IC95% 1,39;4,90), idade (60 a 69 anos/50 a 59 anos) RP = 3,27 (IC95% 1,01;11,24), idade (70 anos e mais/50 a 59 anos) RP = 4,29 (IC95% 1,30;14,29), problemas de saúde nos últimos 15 dias (sim/não) RP = 1,31 (IC95% 1,02;1,77), e atividade física no tempo livre (sim/não) RP = 0,57 (IC95% 0,26;0,97). CONCLUSÕES: A prevalência da doença pulmonar obstrutiva crônica é elevada e está associada ao uso do tabaco e idade acima de 60 anos. Os problemas de saúde freqüentes e redução da atividade física no tempo livre podem ser considerados conseqüências dessa doença.

In Brazil, smoking incidence varies between 9.5% and 21.2% and it is more common among men. In college students incidence can reach 14% depending on the region, which is quite disturbing. Joining college is a crucial period for the commencement or maintenance of smoking. The Knowledge among college students about tobacco use is critical to devise strategies for intervention in this population. The objectives were to establish the occurrence of smoking and risk factors, nicotine dependence in college students and college goers. We interviewed students, teachers and administrative personnel from the Philosophy and Science School at UNESP at Marilia, from both sexes, regardless their age, which visited the First Week Against Tobacco event. The sociodemographic data, smoking status, time as a smoker, cigarettes smoked, date when they started smoking, history of smoking in the family, friends or associates were questioned. We also assessed the degree of motivation to quit smoking and the degree of nicotine dependence. Data were presented using descriptive statistics. Comparisons between categorical variables were made using the chi-square test (p <0.05). A total of 432 people, 180 men and 252 women, average aged 22.6 ± 6.9 years were researched. From the volunteers studied, 267 (61.8) had tried cigarettes and 171 of them (64%) reported that they were offered by friends. As a whole, 79 (18.3%) of these people were smokers, 52 (65.8%) reported intending to quit smoking and in 37 of them (46.8%), the degree of nicotine dependence was very low. Of all the smokers, 63 had smokers in the family and all of them had friends who smoked. 28.9% of all men were smokers and 10.7%of all women. The occurrence of smoking was 18.3% and the risk factor associated to smoking habit is related to friendship and family, and very low nicotine dependence.

El desarrollo acelerado del polo cerámico de Santa Gertrudes (provincia de São Paulo) en la década de 90, fue causado principalmente por la localización privilegiada de la materia prima asociada al desarrollo tecnológico, las grandes reservas, el acceso fácil por autopistas que facilitan la distribución de los productos y la proximidad de los grandes centros consumidores. Este desarrollo facilitó que este Polo tuviera un boom en el inicio de 2007 en la fase de madurez con una producción de 367 millones de metros cuadrados, transformándose así en el mayor polo cerámico de las Américas. de acuerdo con los estudios geológicos realizados en este trabajo, las rocas de la Formación Corumbataí, origen de la materia prima usada en el polo cerámico, fueron clasificadas en cinco litofacies: maciza, laminada, intercalada I, intercalada II y alterada. Estas litofacies, por sus características mineralógicas y químicas, fueron consideradas arcillas illíticas con porcentaje medio de fundentes. Tomando como referencia las Normas para baldosas cerámicas, las características cerámicas obtenidas en el laboratorio demostraron que la mayoría de la materia prima es compatible con el grupo BIIb (Absorción de agua entre 6 y 10%).
