Aspectos linguístico-ergonômicos em rótulos: avaliação da linguagem verbo-visual de rótulos de embalagens para alimentos achocolatados

We have been living in a world of packed products. The package and the labels support the companies to communicate with the customers in addition to give protection, storage and convenience in proportion to the products that move in the price list. The labels mainly add up a value which helps the companies differ their products and increase the value of the brands among the final customers. However, the information given in the label are not clear sometimes. It displays a verbal-visual defective language resulted from a poor visibility, legibleness and comprehensibleness of the verbal and visual marks. The aim of this research is to verify, according to the costumers‟ view, the level of the clarity in the informative texts, harmony and ergonomic conformity of the package labels in the chocolate powder of the Claralate brand, considering the linguistic aspects presented on the labels. The criteria to evaluate the chocolate package selected were based on the linguistic field: the organization and the structure of the text derided from the classification of the textual genre; the clarity and the comprehension of the language utilized on those labels. From the ergonomic view, the informative and ergonomic conformity, based on the following requirements: legibility, symbols, characters, reading fields and intermission of the written lines. Therefore, the research done july 2007 and added july 2011 had a structured questionnaire in the interview put to the 118 customers of the chocolate package that go shopping in one of the two supermarkets in Floriano, Piauí São Jorge and/or Super Quaresma. The main results of the investigation show that the linguistic aspects in the informative texts of the labels provide the customers‟ expectancy partially, while the consideration of the informative ergonomic analyzed can contribute to the improvement of the information and consequent visual progress of those, on the labels of chocolate package investigated. As recommendation towards the maker of the product, the outcome of the research indicates: harmonize the proportion of the letters and numbers; enlarge the letters size; make the visual information more comprehensive determined by the reading field; put the expiry date in a better visual place

Avaliação dos textos informativos em três embalagens de café

O presente trabalho tem o objetivo de apresentar uma investigação sobre o nível de clareza dos textos informativos dos rótulos de embalagens de café torrado e moído, considerando os aspectos lingüísticos e ergonômicos presentes nos rótulos do produto. Lingüisticamente analisar se a linguagem utilizada nos rótulos é adequada para a compreensão das informações pelo consumidor, ainda expor como a lingüística preconiza a organização e estruturação dos textos a partir da classificação do gênero textual. Do ponto de vista da ergonomia a pesquisa pretende identificar a conformidade ergonômica presente nas informações dos rótulos das embalagens de café. Devido à evolução das atividades comerciais, a embalagem passou ao longo do tempo a acumular funções, transformando-se em um considerável veículo de comunicação, informação e sedução do seu público consumidor, por isso, a adoção de normas adequadas relativas às informações pode evitar que o consumidor desenvolva conceitos inadequados ou até mesmo empregue erroneamente um produto alimentício em sua dieta. A engenharia de produção considera importante a inserção de melhores práticas de produção e gestão do produto nas empresas, com vistas ao aumento de sua competitividade, compatibilizando as características ergonômicas do produto embalagem, com as necessidades do consumidor enquanto parte integrante do processo de desenvolvimento do produto. A pesquisa propõe, então, um roteiro para avaliação dos rótulos de embalagens, utilizando para isso um questionário com questões fechadas e uma aberta, aplicados em consumidores de café torrado e moído no momento da compra em quatro supermercados de Natal. Os principais resultados da investigação demonstram que os aspectos lingüísticos dos textos informativos foram considerados bons, enquanto os aspectos ergonômicos informacionais analisados podem vir a contribuir para uma melhoria visual das informações contidas nos rótulos das embalagens das marcas de café investigadas

Mecanismos de segurança para um sistema cooperativo de armazenamento de arquivos baseado em P2P

Previous works have studied the characteristics and peculiarities of P2P networks, especially security information aspects. Most works, in some way, deal with the sharing of resources and, in particular, the storage of files. This work complements previous studies and adds new definitions relating to this kind of systems. A system for safe storage of files (SAS-P2P) was specified and built, based on P2P technology, using the JXTA platform. This system uses standard X.509 and PKCS # 12 digital certificates, issued and managed by a public key infrastructure, which was also specified and developed based on P2P technology (PKIX-P2P). The information is stored in a special file with XML format which is especially prepared, facilitating handling and interoperability among applications. The intention of developing the SAS-P2P system was to offer a complementary service for Giga Natal network users, through which the participants in this network can collaboratively build a shared storage area, with important security features such as availability, confidentiality, authenticity and fault tolerance. Besides the specification, development of prototypes and testing of the SAS-P2P system, tests of the PKIX-P2P Manager module were also performed, in order to determine its fault tolerance and the effective calculation of the reputation of the certifying authorities participating in the system

Armazenamento de botões florais para produção de sementes de abóbora com polinização manual

O objetivo deste trabalho foi verificar a influência do armazenamento de botões florais masculinos por diferentes períodos, na produção e qualidade de sementes de abóbora cultivar Piramoita. O experimento foi desenvolvido no período de agosto a dezembro de 2005. O delineamento experimental utilizado foi em blocos ao acaso, com quatro repetições e cinco tratamentos: polinização manual com flor aberta no dia (zero dia de armazenamento) e polinização manual com botões armazenados em geladeira (7 ºC) por 1, 2, 3 e 4 dias. Quanto maior o período de armazenamento dos botões florais masculinos, menor a produção (número e massa) de sementes por fruto e a massa média do fruto. Também há uma perda de vigor e germinação das sementes quando se aumenta o período de armazenamento dos botões florais, reduzindo sua qualidade.

Simulação de reservatórios não convencionais para armazenamento de gás natural veicular

The investigation of viability to use containers for Natural Gas Vehicle (NGV) storage, with different geometries of commercial standards, come from necessity to join the ambient, financial and technological benefits offered by the gas combustion, to the convenience of not modify the original proposal of the automobile. The use of these current cylindrical models for storage in the converted vehicles is justified by the excellent behavior that this geometry presents about the imposed tensions for the high pressure that the related reservoirs are submitted. However, recent research directed toward application of adsorbent materials in the natural gas reservoirs had proven a substantial redusction of pressure and, consequently, a relief of the tensions in the reservoirs. However, this study considers alternative geometries for NGV reservoirs, searching the minimization of dimensions and weight, remaining capacity to resist the tensions imposed by the new pressure situation. The proposed reservoirs parameters are calculated through a mathematical study of the internal pressure according to Brazilian standards (NBR) for pressure vessels. Finally simulations of the new geometries behavior are carried through using a commercially avaible Finite Element Method (FEM) software package ALGOR® to verify of the reservoirs efficincy under the gas pressure load

Composto orgânico no potencial fisiológico de sementes de brócolis após o armazenamento

The study was carried out with the objective to evaluate the broccoli seeds (cultivar Ramoso Santana) germination and vigor from plants cultivated with different organic compost levels and after storage in dry chamber. At seed production stage, the experiment was conducted in randomized complete blocks design, with five treatments (0; 30; 60; 90 and 120 t ha(-1) of Biomix (R) organic compost) and four replications. Soon after harvesting and after 12 and 24 months of conservation in dry chamber room (20 degrees C and 40% relative humidity) it was evaluated germination, following seed analisys rules, and vigor (first count of germination and germination speed index - IVG). There were no differences in germination and vigor in seeds as soon as they were harvested and after 12 month of storage. After 24 months of storage, the lesser the organic compost rates, the lesser seed germination and IVG, with respective values, without compost, of 69% and 12,3. For another hand, the highest values for germination and IVG, 82% and 16,1, respectively, were obtained with the highest rate of organic compost (120 t ha(-1)).

Qualidade fisiológica e armazenamento de sementes de milheto em função da época de semeadura

Pearl millet is recommended to produce dry matter for no-tillage system, as forage or for grain yield. The sowing time affects the crop development; thus, it can affect seed quality and initial storage conditions. The present research had as objective to evaluate the effects of sowing time on pearl millet seeds quality during the storage. Pearl millet seeds from twelve monthly sowing times were stored in environmental conditions, with no temperature and relative humidity control, and evaluated by seed moisture content, germination and vigor (first count of the germination test and electrical conductivity) for 0, 27 and 42 months of storage. The completely random design was employed, as a factorial experiment 12 x 3 (sowing time x storage time), with four replications. Means were compared by Tukey test (p <= 0.05). Pearl millet seeds produced in September resulted in the production of seeds with high germination and vigor, evaluated by the electrical conductivity test. The capacity of quality conservation of pearl millet seeds, for different storage times, is related to crop sowing time.

Armazenamento a frio de ramos porta-borbulhas e métodos de enxertia de cultivares de marmeleiro

Visando a aumentar o aproveitamento do material propagativo, ampliar o período de oferta das mudas de marmeleiro e dinamizar o uso da mão-de-obra no viveiro, faz-se necessário o armazenamento dos ramos porta-borbulhas. Sendo assim, o presente trabalho teve por objetivos estudar a viabilidade da manutenção dos ramos porta-borbulhas de diferentes cultivares de marmeleiro, por meio do armazenamento a frio, e diagnosticar o método de enxertia para promover melhor desenvolvimento do enxerto. Ramos dos marmeleiros 'Japonês' (Chaenomeles sinensis), 'Smyrna', 'Portugal', 'Mendoza Inta-37' e 'Provence' (Cydonia oblonga) foram coletados em julho de 2008. Uma parte dos ramos foi utilizada para a realização da enxertia (métodos de borbulhia e garfagem) em mudas de seis meses de idade do porta-enxerto 'Japonês', e a outra parte foi armazenada sob baixa temperatura (estacas envoltas em papel umedecido, embrulhadas em sacos de polietileno colocadas em câmara fria a 4°C), por 30 e 60 dias. Passados 60 dias, foi mensurada a porcentagem de brotação dos enxertos e, ao final de 120 dias da realização das enxertias, foram mensurados o comprimento, o diâmetro e a massa seca média dos enxertos. Concluiu-se que, apesar de as cultivares apresentarem diferença, recomenda-se que os ramos sejam armazenados por até 30 dias, sendo utilizada a enxertia pelo método de garfagem.

Posição do racemo e do fruto na qualidade fisiológica de sementes de mamona durante o armazenamento

The present research had as objective to evaluate the influence of raceme and fruit position on physiological quality of castor bean seeds (Ricinus communis L.) during storage of cultivar AL Guarany 2002. The treatments were: position of the raceme in plants (primary, secondary and tertiary) and position of fruit in racemes (low, medium and high). After fruit extraction, seeds were stored under environmental conditions for twelve months. The experimental design used was the completely randomized in a split-plot arrangement. Main plots consisted of the interaction raceme x fruit position and subplots were the storage time. Physiological quality was evaluated quarterly through tests of moisture content, germination and vigor (first count, accelerated aging, seedling length and seedling dry matter). Neither the position of racemes in the plant nor fruit in racemes does not affect germination of castor bean seeds. Dormancy of castor bean seeds decreases during storage, but also increases percentage of abnormal seedlings, seedling dry matter and root, hypocotyl and seedling total length.

Efeitos do ambiente de armazenamento na qualidade de sementes de sorgo-sudão

O trabalho objetivou avaliar efeitos do ambiente de armazenamento na qualidade de sementes de sorgo-sudão (Sorghum sudanense (Piper) Stapf) de diferentes procedências. Cinco lotes de diferentes origens foram armazenados por nove meses, acondicionados em sacos de papel unifoliado, em quatro condições ambientais: ambiente natural de laboratório (sem controle de umidade relativa e temperatura); 30 a 40% de umidade relativa e sem controle de temperatura (simulada através de câmara seca); 10 a 15% de umidade relativa e 5 a 7ºC de temperatura (simulada através de um refrigerador Frost Free); 40 a 50% de umidade relativa e -20ºC de temperatura (simulada através de freezer). As avaliações laboratoriais, realizadas em intervalos trimestrais, foram: teor de água, massa de mil sementes, germinação, crescimento de plântulas, massa seca de plântulas, envelhecimento acelerado, condutividade elétrica, emergência em campo e índice de velocidade de emergência. O delineamento utilizado foi o inteiramente casualizado, com quatro repetições, num esquema fatorial 4 x 5, e comparação de médias pelo teste de Tukey a 5% de probabilidade. A origem das sementes, relacionada à qualidade das mesmas, mostrou-se como o principal fator a influenciar a conservação. Os ambientes refrigerador e freezer, seguidos da câmara seca, mostraram-se adequadas à conservação de sementes de sorgo-sudão. A capacidade de conservação de sementes dessa espécie relaciona-se com a sua qualidade inicial dependente da sua origem.

Caracterização geológico-geofísica do meio aqüífero fissural : uma contribuição aos modelos de fluxo e armazenamento de água subterrânea

Northeastern Brazil is mainly formed by crystalline terrains (around 60% in area). Moreover, this region presents a semi-arid climate so that it is periodically subject to drought seasons. Furthermore, ground water quality extracted fromwells usually presents poor quality because of their high salinity contents. Nevertheless, ground water is still a very important source of water for human and animal consumption in this region. Well sitting in hard rocks terrains in Northeastern Brazil offers a mean success index of aboul 60%, given that a successful siting is defined by a well producing at least 0.5 m³/h. This low index reveals lack of knowledga about the true conditions of storage and percolation of ground water in crystalline rocks. Two models for structures storing and producing ground water in crystalline rocks in Northeastem Brazil have been proposed in the literature. The first model,tradnionally used for well sitting since the sixties are controlled by faults or fractures zones. This model is commonly referred, in Brazilian hydrogeological literature, as the "creek-crack" model (riacho-fenda in Portuguese). Sites appearing to present dense drainage network are preferred for water well siting - particularly at points where the drainages cross-cul each other. Field follow up work is usually based only on geological criteria. The second model is the "eluvio-alluvial through" (calha eluvio-aluvionar in Portuguese); it is also described in the literature but it is not yet incorporated in well sitting practice. This model is based on the hypothesis that reclilinear drainages can also be controlled by the folietion of the rock. Eventually, depending upon the degree of weathering, a through-shaped structure filled with sediments (alluvium and regolith) can be developed which can store and water can be produced from. Using severalfield case studies, this Thesis presents a thorough analysis ofthe two above cited models and proposes a new model. The analysis is based on an integrated methodological approach using geophysics and structural geology. Both land (Resitiviy and Ground Penetrating Radar- GPR) and aerogeophysical (magnetics and frequency domain eletromagnetics) surveys were used. Slructural analysis emphasized neolectonic aspects; in general, itwas found that fractures in the E-W direction are relatively open, as compared to fracturas inthe N-S direction, probably because E-W fractures were opened by the neotectonic stress regime in Northeastern Brazil, which is controlled by E-W compression and N-S extension. The riacho-fenda model is valid where drainages are controlled by fractures. The degree of fracturing and associated weathering dictale the hydrogeological potential of the structure. Field work in structural analogues reveals that subvertical fractures show consistent directions both in outcrop and aerophotograph scales. Geophysical surveys reveal subvertical conductive anomalies associated to the fracture network controlling the drainage; one of the borders of the conductive anomaly usually coincide wih the drainage. An aspect of particular importance to the validation of fracture control are the possible presence of relalively deep conductive anomalies wihoul continuation or propagalion to the surface. The conductive nature of lhe anomaly is due to the presence of wealhered rock and sedirnenls (alluvium and/or regolilh) storing ground waler which occur associated to the fracture network. Magnetic surveys are not very sensisnive to these structures.lf soil or covering sedirnents are resislive (> 100 Ohm.m), GPR can ba used to image precisely lhe fracture network. A major limialion of riacho-fenda model, revealed by GPR images, is associated to the fact thal subhorizontal fractures do play a very important role in connecting the fracture network, besides connect shallow recharge zones to relalively deep subvertical frecture zones. Iffractures play just a secondary control on the drainage, however, r/acho-fenda model may have a very limiled validny; in these cases, large portions oflhe drainage do nol coincide wilh frectures and mosl oflhewells localed in lhe drainage surrounding would resull dry. Usually, a secondary conlrol on lhe drainage by Ihefraclure networkcan be revealed only wilh detailed geophysical survey. The calha elClv1o-aluvlonarmodel is valid where drainages are conlrolled by folialion. The degree 01 wealhering 01 lhe lolialion planes dictales lhe hydrogeological polenlial 01 lhe slruclure. Outcrop analysis reveals Ihal lolialion and drainage direclions are parallel and Ihal no Iraclures, orfraclures wilh diflerent directions 01 lhe drainage direclion occur. Geophysical surveys reveal conduclive anomalies in a slab lorm associaled 10 lhe Ihrough 01 lhe wealhered rock and sedimenls (alluvium and/or regolith). Magnelic surveys can ofler a very good conlrol on lolialion direclion. An importanl aspect 10 validale lolialion conlrol are lhe presence 01 conductive anomalies showing shallow and deep portions area which are linked. Illhere is an exlensive soil cover, r/acho-fenda and calha eIClv1o-aluv/onar conlrols can be easily misinlerpreled in lhe absence 01 geophysical conlrol. Certainly, Ihis lacl could explain at leasl a part of lhe failure index in well sitting. The model wealhering sack (bolsllo de Intempertsmo in Portuguese) is proposed to explain cases where a very inlensive wealhering occur over lhe crystalline rock so Ihal a secondary inlerslilial porosity is crealed. The waler is Ihen stored in lhe porous of lhe regolilh in a similar mannerlo sedimentary rocks. A possible example ofthis model was delecled by using land geophysical survey where a relalivelyvery deep isolaled conduclive anomaly, in a slab form, was delected. Iflhis structure does store ground waler, certainly Ihere must be a link 01 lhe deep slructure wilh lhe surface in orderlo provide walerfeeding. This model mighl explain anomalous waler yields as greal as 50 m³/h Ihalsomelimescan occur in crystalline rocks in Northeaslern Brazil
