Occupational risk in a glass manufacturing industry unit

Risk assessment is one of the main pillars of the framework directive and other directives in respect of health and safety. It is also the basis of an effective management of safety and health as it is essential to reduce work-related accidents and occupational diseases. To survey the hazards eventually present in the workplaces the usual procedures are i) gathering information about tasks/activities, employees, equipment, legislation and standards; ii) observation of the tasks and; iii) quantification of respective risks through the most adequate risk assessment among the methodologies available. From this preliminary evaluation of a welding plant and, from the different measurable parameters, noise was considered the most critical. This paper focus not only the usual way of risk assessment for noise but also another approach that may allow us to identify the technique with which a weld is being performed.

Estudos bionômicos de Dipetalogaster maximus (Uhler, 1894) (Hemiptera, Reduviidae, Triatominae): III. Dinâmica populacional

A population dynamics study of D. maximus was caried out under laboratory condictions (28-C e 65% ñ 5% U.R.) and the methodology was the same that have been used for hearing this insects. In order to evaluate the population growth rate of this species, during a 24 months period, five colonies started with a couple recently emerged were observed. Each couple (a male and a female) was mantained in a glass container measuring 20 cm of diameter and 20 cm in height with filter paper on the botton. The insects were monthly feeding with normal mice blood, and at this day the number of eggs, nymphal stages and adults was registered. All graphical representations of the populations growth rate showed the same shape. It was found that the average of nymphal stage represented 64.31% of the hole population whereas the oviposition curved showed to be inverse to this one (28.57%) a small percentage of adults was found: males 3.85% and females 3.12%. In this study observations on the biologycal cycle, longevity and fertility rates were also carried out.

Elastic stresses and plastic deformations in 'Santa Clara' tomato fruits caused by package dependent compression

The objective of this work was to study the fruit compression behavior aiming to develop new tomato packages. Deformations caused by compression forces were observed inside packages and in individual 'Santa Clara' tomato fruit. The forces applied by a transparent acrylic lever to the fruit surface caused pericarp deformation and the flattened area was proportional to the force magnitude. The deformation was associated to the reduction in the gas volume (Vg), caused by expulsion of the air from the loculus cavity and reduction in the intercellular air volume of the pericarp. As ripening advanced, smaller fractions of the Vg reduced by the compressive force were restored after the stress was relieved. The lack of complete Vg restoration was an indication of permanent plastic deformations of the stressed cells. Vg regeneration (elastic recovery) was larger in green fruits than in the red ones. The ratio between the applied force and the flattened area (flattening pressure), which depends on cell turgidity, decreased during ripening. Fruit movements associated with its depth in the container were observed during storage in a transparent glass container (495 x 355 x 220 mm). The downward movement of the fruits was larger in the top layers because these movements seem to be driven by a summation of the deformation of many fruits in all layers.

Suorituskyvyn mittaaminen lasi- ja alumiinirakentamisen pk-yrityksissä

Diplomityön taustana oli oletus suorituskyvyn mittaamisen vähäisyydestä lasi- ja alumiinirakentamisen pk-yrityksissä. Tämän takia haluttiin tutkia mitataanko suorituskykyä ja jos mitataan, miten sitä tehdään sekä minkälainen järjestelmä sopisi kyseisille yrityksille. Lasi- ja alumiinirakentamisen suorituskyvyn analysoinnin tilannetta kartoitettiin haastattelututkimuksella, jossa kävi ilmi, että se tosiaan on vähäistä. Tutkimukseen osallistuneissa yrityksissä seurattiin pääasiassa liiketaloutta ja tulosta, ja näitäkin suppeasti. Laajemmalle mittaamiselle todettiin kuitenkin olevan tarvetta. Tämän jälkeen haastattelututkimuksen pohjalta suunniteltiin työssä mukana olleelle Case-yritykselle mittaristo. Suunnitteluvaiheessa valittiin yrityksen visioiden ja strategian mukaisesti neljä mitattavaa suorituskyvyn osa-aluetta ja näille mittarit. Mittariston suunnittelun jälkeen siirryttiin rakennusvaiheeseen. Järjestelmäksi valittiin SAKE, joka on helppokäyttöinen ja erityisesti pk-yritysten tarpeisiin suunniteltu työkalu. Tämän suorituskyvyn mittariston avulla lasi- ja alumiinirakentamisen yritykset voivat tehostaa toimintaansa ja ulottaa suorituskyvyn mittauksen osa-alueilla joita ei aiemmin ole huomioitu.

Método simples e acessível para determinar amônia liberada pela cama aviária

A amônia é um gás altamente irritante e causador de estresse às aves confinadas, o que leva à perda de peso, podendo até causar a morte. Por esse motivo, existe grande interesse em se determinar a quantidade de amônia liberada por diferentes camas aviárias e de diferentes condições, bem como os fatores que influenciam a produção desta substância. Assim, idealizou-se o presente trabalho com o objetivo de desenvolver e padronizar uma metodologia simples, acessível, exeqüível para avaliar camas de frangos submetidas a diferentes condições (diferentes tratamentos, tempos de confinamento e temperatura) e capaz de determinar a potencialidade da liberação de amônia pela cama de frangos nos galpões. A metodologia baseou-se na adaptação do método da microdifusão, que consta da incubação da cama em um frasco de vidro com capacidade de 500 mL. Sobre a superfície do material incubado coloca-se um béquer de 50 mL contendo 10 mL de solução de ácido bórico 2% (m/v) para fixar a amônia exalada pela cama aviária. Esse sistema é fechado e incubado por 15 horas a 30°C e, após, a solução fixadora é retirada e titulada com ácido sulfúrico 0,05 N, usando como indicador uma mistura de verde de bromocresol e alaranjado de metila. O método proposto apresenta precisão para ser usado em experimentos e utiliza material barato e reagentes facilmente encontrados nos laboratórios.

Qualidade fisiológica de sementes de Sebastiania commersoniana (Baill.) Smith & Downs (branquilho - Euphorbiaceae) durante o armazenamento

This paper aims to evaluate the physiological quality of Sebastiania commersoniana seeds stored in cloth bag, plastic bag and glass container and kept in two conditions: laboratory workbench and cold chamber (4 ± 2°C e 80% relative humidity - RH) for 531 days. Periodically, samples were taken in order to determine the moisture content and to perform germination tests. The experimental design was completely randomized, in factorial scheme of 3 × 2 (wrappings × conditions), for each period of storage evaluated (0, 158, 271, 389 and 531 days of storage). Supplementary, a polynomial regression was adjusted in order to describe the physiological quality of the seeds for the different conditions during the experimental period. The results lead to the following considerations: a) storage under variable temperature and air humidity (laboratory workbench) can be used for periods of over five and a half months, with the seeds stored in cloth bag, plastic bag or glass container; b) the physiological quality of the seeds was not hardly altered when stored in cold chamber in cloth bag, plastic bag and glass container for over 18 months.

Desempenho mecânico de embalagens rígidas utilizadas na indústria agroquímica: estudo de compressão

The world population is growing at exponential scales, thus the demand for food grows significantly. The use of pesticides is seen as a way to meet the demand for food and increase the efficiency and productivity of the agricultural sector. BASF SA in partnership with packaging suppliers represent a remarkable scene in the Brazilian market in the agrochemicals sector. In 2014, the Department of Agro from BASF Packaging, identified in its production process certain deformation of its rigid packaging during the filling process of pesticides. This phenomenon is probably caused by the low resistance to compression that the package is used. In order to eliminate the deformation of rigid packaging arising from the filling step, a study will be conducted in conjunction with the supplier JET UNIPAC whose on line problems occurred more frequently. The study is to identify the strength of the rigid containers standardize a compression resistance value at which the package is not deformed after the filling step. This study will present an investigation through experiments combined with theoretical concepts in order to determine possible causes for the emergence of this phenomenon. At the end of the study, a solution to eliminate or reduce to the maximum the packaging deformation problem appears

Sustainable waste recycling solution for the glass fibre reinforced polymer composite materials industry

In this paper the adequacy and the benefit of incorporating glass fibre reinforced polymer (GFRP) waste materials into polyester based mortars, as sand aggregates and filler replacements, are assessed. Different weight contents of mechanically recycled GFRP wastes with two particle size grades are included in the formulation of new materials. In all formulations, a polyester resin matrix was modified with a silane coupling agent in order to improve binder-aggregates interfaces. The added value of the recycling solution was assessed by means of both flexural and compressive strengths of GFRP admixed mortars with regard to those of the unmodified polymer mortars. Planning of experiments and data treatment were performed by means of full factorial design and through appropriate statistical tools based on analyses of variance (ANOVA). Results show that the partial replacement of sand aggregates by either type of GFRP recyclates improves the mechanical performance of resultant polymer mortars. In the case of trial formulations modified with the coarser waste mix, the best results are achieved with 8% waste weight content, while for fine waste based polymer mortars, 4% in weight of waste content leads to the higher increases on mechanical strengths. This study clearly identifies a promising waste management solution for GFRP waste materials by developing a cost-effective end-use application for the recyclates, thus contributing to a more sustainable fibre-reinforced polymer composites industry.
