Análise da prática de meditação em duas escolas do município de Rio Claro - SP

Nowadays, meditation had become larger than the mystic’s scope, entering the academy through the scientific interest in this topic. Results documented for so many centuries or the experienced monks that practice meditation for a long time are the aims for researches that want, ultimately, establish the real effects of such techniques upon the human body. Research has gone far, and many effects can be evaluated using more precise methods, specially in the medical field and neuroscience, which had greatly backed up new discoveries about the correlation between the mind, emotions, thoughts and the body, making so that mediation can walk the therapeutic ways and complementary health with more certainty and reliable results, as it is happening with acupuncture and yoga. Facing a promising scenario in the correlation between meditation and life’s quality, well being sensation and happiness, there is the possibility of using it in schools, since because of the difficulties and present challenges, those factors are not commonly associated with the acts of teaching and learning, and acupuncture and Yoga have more restrictions because of their own limitations of time and space necessary for their wide application. Therefore, the current study focused on contextualizing the meditation’s fundaments in the scientific perspective, and apply it, even if qualitatively, in two schools of Rio Claro municipality, researching 57 students from Educação de Jovens e Adultos (EJA). Therefore, it was chosen only one meditation tecnique to be applied on the treatment group. As for the control group, it perfomed normal breathing, i.e., without tecniques. The differences were then analyzed through the filmings of all the sessions of the meetings, counting the number of movements and the agitation among the students for the two groups. Another method of analysis was forms filled by both groups and the presence in a meeting at Unesp – Rio Claro. At the end,...

Manejo pré-abate de bovinos

The pre-slaughter moment begins with the animal´s loading on the farm and ends up in its drain. It is a period in which the animal is under physical stress caused by hunger, thirst, fatigue, injuries, and extremes of temperature and psychological stress, due to restraint, handling, innovation and fear. Stress and inappropriate handling bring bad consequences for the final product´s quality, requiring better handling conditions, facilities and equipment. Examples of consequences of mishandling: meat with abnormal color, DFD meat (dark, firm and dry), reduced product´s shelf life, bruises and broken bones in carcasses. The operators should be trained and oriented on the basic principles of biology, behavior and management of cattle. At every step of the pre-slaughter moment, the animals should be handled calmly and quietly to avoid excitement and stress. Operators should avoid shouting, whistling or any noise since cattle have very sensitive ears and can become stressed. If the animals refuse to move, the cause of the problem should be determined

Propriedades térnicas de géis e xerogéis híbridos de sílica/orgânico à base de GPTS-TEOS com diferentes concentrações de GPTS

In the present work the thermal characteristics of gels and xerogels of Silica/organic hybrids derived from different concentrations of GPTS-TEOS were investigated by thermal analysis (TG, DTA, and DSC). The preparation of gels of the Silica/organic hybrid matrix was held through the sol-gel process, consisting by the hydrolysis of alkoxides GPTS and TEOS in proportion (1:1) and (1:2) that was promoted in acidic conditions under reflux and stirring at 80oC/2h, producing the matrix in the colloidal state (sol). Gels were prepared by addition of NH4OH to the sol, promoting gelation of sol in sealed plastics containers. Part of the gels samples was analyzed by TG, DTS and DSC techniques in order to characterize water loss and degradation of the polymeric “epoxy” groups present in the structure of the silica derived from the GPTS alkoxide. Another set of samples was dried at 80oC/48h to obtain xerogels (dried gels) and analyzed by the same techniques. We obtained the characteristics temperatures of the matrix by the techniques DTA, DSC and TG, under measurements of thermal analysis until 800oC and 600oC in case of DSC. By thermal analysis (TG, DTA, and DSC) the main endothermic events (loss of water, melting, pyrolysis) and exothermic events (burning of the polymer) of the GPTS-TEOS matrix were determined

Influência de parâmetros nutricionais e físicos sobre a produção de Lipase por Penicillium janthinellum

As lipases (triacilglicerol acil hidrolases, E.C. 3.1.1.3) constituem uma classe de enzimas que catalisam a hidrólise de ligações ésteres dos triacilgliceróis de cadeia longa, operando na interface óleo/água. Em meios orgânicos, dependendo da quantidade de água, essas enzimas podem catalisar reações de esterificação e transesterificação, atuando como biocatalisadores da síntese de óleos e gorduras. As lipases destacam-se em processos industriais, nos quais são utilizadas como aditivos na produção de detergentes, de papel e celulose, na indústria de laticínios, de cosméticos, entre outros. As lipases microbianas são de maior interesse para aplicação em biotecnologia e em química orgânica, sendo necessária a prospecção de novas fontes de lipases com propriedades distintas. O presente trabalho avaliou a influência de diferentes meios de cultura, do tempo de cultivo, de fontes de carbono e sua concentração, de fontes de nitrogênio, agitação, pH e temperatura sobre a produção de lipase extracelular pelo fungo filamentoso Penicillium janthinellum, isolado de solo de região de Mata Atlântica. A avaliação das melhores condições de cultivo foi realizada através da análise da atividade enzimática, acompanhada pela determinação do íon ρ-nitrofenol liberado na hidrólise do substrato sintético ρ- nitrofenil palmitato. Os experimentos foram realizados em frascos de Erlenmeyer de 125mL contendo 25mL de meio de cultivo, inoculados com 1mL de suspensão contendo 107 conídios, e incubados a 28°C com agitação de 160 rpm e pH 5,5. Entre os quatro meios de cultura testados, o melhor resultado (0,476 ± 0,04 U/mL), com 5 dias de cultivo, foi verificado com o meio 2 composto por (g/L): bacto-peptona 5,0, extrato de levedura 1,0, NaNO3 0,5, KCl 0,5, MgSO4·7H2O 0,5, KH2PO4 2,0 e azeite de oliva 10,0)...

Análise estrutural de aerogéis via espalhamento de luz a baixo ângulo

The sol-gel process is a method for obtaining vitreous or vitro-ceramic materials which, are prepared a sol and by drying the liquid phase. This technique has been used extensively for the preparation of glassy gels, films, fibers and particles from the hydrolysis and polycondensation reactions of metal alkoxides. The usual methods for drying are: evaporation drying (xerogels), freeze drying (criogéis) and via supercritical CO2 extraction (aerogels). In the present work, we studied the preparation of silica gels by the sol-gel process from the hydrolysis of alkoxides tetraethylorthosilicate (TEOS) and 3-glycidoxypropyltrimethoxysilane (GPTS). The hydrolysis was promoted from GPTS and TEOS in proportion (4: 1) under acidic conditions. The hydrolysis reaction was promoted inside a Becker at room temperature. After hydrolyses the prepared sol had pH 2, and kept under mechanical agitation for a period of 1 hour. In order to accelerate the polycondensation reaction, the pH was corrected to a value near 5 by slowly adding NH4OH. Then the sols were leaked in sealed polycarbonate containers and maintained for 20 days at 40°C for gelation. Silica aerogels were prepared via supercritical CO2 extraction of the wet gel at temperature and pressure higher than 31°C and 74 atm, in an autoclave specially developed for the process. The structural characteristics were studied in the dry gel (aerogel). Aerogels were then characterized by nitrogen adsorption and small angle light scattering. The nitrogen adsorption data were analyzed for the determination of the BET specific surface (SBET), the total pore volume Vp, the pore mean size (lP=4Vp/SBET), the particle mean size (lS) and the pore size distribution (PSD). And the data from small angle light scattering were analyzed to determine the correlation function (γ'), the area per unit volume (S/V), average pore size (l ) and the average particle size...

Produção de celulases por fungos filamentosos da Antártica: busca por novo recurso genético para obtenção de bioetanol

Na busca de novos recursos genéticos capazes de produzir enzimas celulolíticas a baixas/médias temperaturas, o continente Antártico vem demonstrando ser um ambiente bastante promissor. Neste contexto, o objetivo do presente trabalho foi avaliar a influência de diferentes fatores na produção de celulases por fungos filamentosos isolados de amostras da Antártica visando otimização do processo possível aplicação das mesmas na produção de etanol de segunda geração. Foram utilizados os fungos L1-1 e E5B da Central de Recursos Microbianos da UNESP (CRM-UNESP) os quais foram previamente selecionados devido ao potencial celulolítico. O delineamento experimental foi utilizado para analisar a influência de variáveis independentes na produção enzimática. A quantificação da celulase foi realizada pelo método do ácido dinitrosalicílico (ADNS). Antes de iniciar à aplicação dos planejamentos experimentais, foram adotadas estratégias para tentar minimizar e otimizar ao máximo o potencial dos isolados, as quais resultaram no estabelecimento da melhor agitação e a temperatura para a produção de celulase em 150 rpm e 20°C, para os dois isolados estudados. Inicialmente os fungos E5B e L1-1 apresentavam suas produções enzimáticas em 0,233U/mL e 0,342U/mL, respectivamente (antes da aplicação dos desenhos experimentais). Durante a condução do planejamento experimental do tipo Plackett&Burman(PB), foi verificada a preferência dos isolados pela fonte de carbono glicose, com efeito significativo na produção de celulases para os dois isolados. Tendo em vista o seu elevado custo comercial, foram realizados estudos com a sacarose, uma fonte de carbono alternativa e mais barata, bem como indutores enzimáticos. Após três planejamentos experimentais do tipo PB, foi selecionado o isolado L1-1 como o melhor produtor da enzima celulase. Após a condução de um quarto planejamento experimental do tipo Fatorial Fracionado 24-1, as...

Poluentes orgânicos persistentes em ar interior: desenvolvimento de método de extração em adsorvente para amostragem ativa

Persistent Organic Pollutants (POPs) are chemical substances extraordinarily toxic and persistent in the environment. Due to these properties, POPs are targets of the Stockholm Convention which aims to provide means to eliminate production and use by encouraging the reduction and, where possible, eliminating the release of these contaminants to the environment. One of the articles of this _Convention aims to assess the basal levels of such substances in the environment to monitor both the reduction of release to the environment, and to assess human exposure, using analyzes of milk and air for example. Although efforts to control POPs production and release to the environment have been made, data about their levels in Brazil are still scarce, mainly in the atmosphere or indoor environment. Considering the permanence of people inside its house, this study presents a method for POP extraction from XAD-2 sorbent employed in indoor air sampling, with identification and quantification by GC-ECD. GC-ECD linear range of the studied analytes, congeners of polychlorinated biphenyls (PCB) (28, 52, 101, 118, 138, 153 and 180), DDTs and their metabolites (DDDs, DDEs) and endosullan (isomers c - and 13 - and metabolite endosulfan sulfate) ranged between 0.5 and 16.0 ng mL-I with r2 > 0.967. The method developing consist of selecting the extraction solvent system by agitation (90 rpm, 1 hour) with n-hexan,e (2 mL) or n-hexane:acetone (1:1, v/v) (2 mL), concentration the extract with a gentle N2 stream, and evaluation of breakthrough with passage or air through the fortified XAD-2 cartridge before extraction, employing a low volume air suction pump (Pump Model 224 universal-PCXR8; 5-5000 mL min-1, SKC Inc., Eighty Four, PA, USA), Calibrator Dry-Cal DC-Lite (BIOS, Butler, NJ, USA)). Two fortification levels were employed, 15 and 30 ng. After selecting n-hexane as extraction solvent, with accuracy and precision ranging...
