Avaliação dos resíduos sólidos gerados no Restaurante Universitário da UNESP de Rio Claro: uma análise do potencial de compostagem

A consequence of population growth is the increased generation of solid waste, which requires environmentally and economically viable suitable disposal sites. The scarcity of such sites makes necessary to adopt non-generation measures, reduction, reuse , recycling and treatment of solid waste before final disposal of waste. This paper presents the quantification and qualification of organic waste generated in each sector of the University Restaurant (UR) , by proposing indicators of waste generation per meal (index of waste) . Then, from the characterization of the waste management practices adopted internally, evaluates the potential deployment of the composting process for organic waste, with signaling for opportunities to improve waste management. The diagnosis of waste generation was made based on data collected during the period of 10 days. The waste were classified into 3 groups (organic, recyclable and waste) in each sector of the restaurant ( pre preparation , kitchen and tray return) . The results reveal that 33 % of the waste generated in the UR currently has the potential to be composted in a suitable place on campus. Every meal served generat approximately 124g of waste, of which 35g are organic waste of the pre preparation sector, 49g are remnants of food in the tray’s return and 40g are other kinds of waste, including recyclable and non recyclable. You can still get a higher percentage of compostable if the trays pre-wash is not performed with detergent and water. To minimize the generation of waste trays can be replaced by plates and skimmers and ladles can be replaced by smaller ones. The food exposed in the counter but not consumed, can be distributed to students after the restaurant is closed so this material would not be disposed in the garbage

Avaliação da produtividade no trabalho organizado em turnos em uma empresa vidreira

Work organized in shifts, either for technological, social or economic imposition, allows the best use of means of production, increasing the overall productivity of the enterprises. At the same time, this type of work harms the individual productive capacity of workers, particularly those involved in the night shift. The objective of this work was to assess the behaviour of production in a continuous line and subjected to work organized in shifts. Through the statistical method of analysis of variance, Spearman's test and Tukey's method, was analysed the distribution of the productivity index measured in three fixed shifts of work in a glass company. The productivity index, provided by the integrated management system of the company, refers to the ratio of actual productivity to total productivity. The statistical analysis shows that factors of production, such as allocation of workers, do not interfere with productivity, showing an unexpected pattern, where the average productivity for the three shifts are close and the correlation between the number of workers on the line and productivity is low. The conditions of production had an adverse work environment with exposure to noise, heat, vaporized mist of lubricating oil and risk of accidents. The findings show that the calculation of productivity in use is limited and its use in company’s production control may produce distortions. It is proposed to examine alternative calculations methods that consider the overall productivity

Avaliação teórico-experimental da distribuição de dose absorvida em radioterapia em tumores de pele

O trabalho propõe rotinas computacionais usando o Método de Monte Carlo com o Código MCNP-5, para analisar os perfis de dose de radiação liberada nos tratamentos de tumores de pele e otimizar os cálculos radiométricos dos feixes de radiação estudados. Foram realizadas medidas dosimétricas do feixe de radiação, comparando os resultados obtidos com os respectivos valores fornecidos pelo serviço de física médica das instituições, com resultados informados pelo fabricante do equipamento e com as simulações computacionais efetuadas com o Código MCNP-5. A quantificação dos erros relativos percentual entre os resultados simulados e os fornecidos pelo Serviço de Radioterapia (E1), os informados pelo fabricante (E2) e os medidos experimentalmente (E3) são inferiores a 4,0% e validam a metodologia computacional proposta para avaliação do comportamento do feixe de raios-X superficial e do feixe de raios γ da unidade de Cobaltoterapia. A metodologia de análise do espectro energético e da curva de porcentagem de dose profunda (PDP) desenvolvida neste trabalho pode ser estendida para estudos de outros feixes clínicos e subsidiar os dados radiométricos utilizados nos planejamentos e cálculos de dose realizados pelo profissional da física médica na sua rotina nos Serviços de Radioterapia

Avaliação da estratégia de controle de enchentes através de reservatórios de detenção de águas pluviais na sub-bacia do Alto Tietê - São Paulo

A rápida expansão do espaço urbano no Brasil ocorreu e continua ocorrendo, geralmente, de forma desordenada e sem perspectivas imediatas de ordenação das práticas de uso e ocupação do solo. O planejamento da ocupação do espaço urbano, baseado na racionalidade capitalista, embora englobe fundamentos interdisciplinares, na prática tem sido realizado dentro de um âmbito mais restrito do conhecimento, desconsiderando aspectos fundamentais dessa dinâmica. Essa situação tem resultado em grandes transtorno e custos para a sociedade e para o meio ambiente, atingindo diretamente os sistemas de drenagens urbanos e resultando no crescimento dos eventos de cheia. Assim, o planejamento urbano vem buscando alternativas que possibilitem o alcance do desenvolvimento urbano sustentável. Neste sentido, este trabalho objetiva avaliar qualitativamente a implantação reservatórios de detenção implantados no alto curso da sub-bacia do Alto Tietê, de modo a avaliar os problemas apresentados através da realização de um inventário dos avanços atingidos na incorporação destas medidas no gerenciamento dos sistemas de drenagem nesta subbacia.

Identificação e avaliação da resistência antimicrobiana de leveduras em vegetais minimamente processados

The consumption of minimally processed vegetables has been growing due to consumer demand for products easy to prepare. As it is extremely manipulated, this product can be contaminated with spoilage organisms such as yeasts, that have the ability to decrease the shelf life of food. In this sense, seeking to concerns about the resistance of microorganisms to sanitation methods for food industries and given the need for more studies of the antimicrobial power of ozone, this study aimed to isolate and identify the yeasts present in minimally processed vegetables, and check their antimicrobial resistance to sodium hypochlorite and ozone. 84 samples of minimally processed vegetables were collected. From them, 47 yeast cultures were isolated and submitted for identification and testing of resistance to sodium hypochlorite sanitizers (50, 100, 200 and 400 ppm) and ozone (0.25 and 0.5 ppm). From the total yeast isolated, 85.1% corresponds to Cryptococcus laurentii, 12.8% to Arxula adeninivorans and 2.1% to Debaryomyces hansenii var. fabryii. All of them were resistant to the sanitizers sodium hypochlorite and ozone at all concentrations tested. Given these observations, some actions must be taken during processing to avoid contamination with deteriorative microbiota.

Avaliação da Taxa de Exposição em Exames Radiológicos Realizados em Procedimentos Cirúrgicos - Minimização dos Riscos em Indivíduos Ocupacionalmente Expostos

This paper consists in the evaluation of the exposure rate to ionizing radiation to which professionals working in surgical procedures which require radiological examinations are subjected. Were initially performed real-time readings of exposure rate within four distinct operating rooms during the execution of four surgical procedures that made use of fluoroscopy equipment (including three orthopedic surgeries, one in the shoulder, one in the arm, another for deployment of metal pin in the leg region, and a fourth for vascular procedure); in these surgeries were used ionization chamber detector and an electrometer. In order to check the values achieved, was made a re-evaluation of the distribution of the rate of exposure to radiation, from the surgical procedures, now with thermoluminescent dosimeters (TLDs). For this, thirty TLDs were distributed in the operating rooms, arranged in points of interest as occupation by professionals. The TLDs were prepared for thirty consecutive days, after which they were removed and replaced with new dosimeters not exposed yet. The dosimeters were subjected to reading of the rate of exposure; this procedure was repeated for four months without interruption. The quantification of the results sought primarily to convert the rate of exposure for equivalent dose rate, both in measurements with ionization chamber as in measurements with TLDs, in order to highlight the presence of the biological effect of ionizing radiation for comparisons within scientific context. Then, the results were plotted to establish the relationship between the values of equivalent dose and the distance to the central axis of the x -ray source, confirming the inverse square law for distance. Finally, the values were associated with the maximum limit recommended by the legislation for occupationally exposed individuals. The methodology for the analysis and quantification of the data in this work aims at implementing a work plan that meets ...

Avaliação do índice de Litle em indivíduos que utilizaram o aparelho funcional T4K

The study aimed to assess the degree of dental crowding correction on the lower anterior region of patients treated with T4k functional appliance using Little’s irregularity index. Twenty caucasian patients of both gender (10 female and 10 male) were selected. They featured malocclusion Class I and II in mixed dentition, with chronological age between 5.7 and 11 years. The treatment lasted from 1 year and 11 months up to 3 years and 11 months. Lower anterior crowding was measured using Little’s irregularity index. Measurements were obtained on study models achieved before and after functional orthopedic therapy, using a digital caliper in millimeters and placed parallel to the occlusal plane. Overjet and overbite measurements were also performed using a caliper. Results demonstrated that the therapy provided significant decrease in overjet (average = 1.55 mm) and also in the irregularity index (average = 1.23 mm). There was a nonsignificant raise in overbite. There was no relation between the studied variables and the treatment period or even with the patient’s age in the beginning of the therapy. The treatment with T4k resulted on reduction and improvement of dental crowding.

Avaliação das dimensões e relacionamento dos arcos dentários após tratamento com Bionator de Balters

The deficiency of data in the literature took us to evaluate the Bionator of Balters appliance in the alterations of the dimensions and the relationship of the dental archs in children with malocclusion Class II, division 1 of Angle. The experimental group was constituted by 36 pairs cast Caucasians patients, aged between 7 years and 10 months - 11 years and 8 months, being 10 females and 8 males. The Levene´s test showed statistical evidences of likeness among the groups. Statistical analysis was preceded and showed significant alterations (p < 0,005) in the variable indicatives of maxillary first molars' distance, overjet, upper arch total length, upper arch anterior length, right molar relationship, left molar relationship, right canine relationship and left canine relationship. On the other hand, there wasn't significant alteration related to the lower arch and maxillary intercanines distance. The Balters' Bionator appliance had a favorable effect in the improvement of the correction of the malocclusion in Class II (foremost in molars and canines relationship) and transversal increase of the upper arch, mainly in the posterior area of arch.

Avaliação em modelos digitais das modificações ocorridas em modelos de gesso em função do posicionamento da moldeira

The objective of this study was to assess if the positioning of the impression tray could cause plaster casts distortion during gypsum setting time. fifteen pairs of master models were cast with alginate impression material and immediately poured with gypsum. impressions were allowed to set with the tray in the not inverted position (group a) or in the inverted position (group b). the plaster models were digitized using a laser scanner (3shape r-700, 3shape a/s). tooth size measurements and distances were obtained using o3d software (widialabs, brasil) measurement tools. data were analyzed by paired t test and linear regression with 5% significance. most measurements of both groups were similar, except for the lower intermolar distance. it was not possible to corroborate the presence of distortions owing to the position of the impression tray during gypsum setting time.
