Utilização de 5S, Kanban e Layout para a melhoria do controle de estoque em um varejo de materiais para construção

Many small businesses suffer from a lack of control of goods stored. This lack of control affects other areas of the company as purchase, that can’t buy material in an advanced and accurated way. It also affects services provided by the company, especially when it is a store because for sell something it is necessary to have the material in the right time. Futhermore, the business isn’t able to identify obsolete items in stock, theft and vandalism, loss or damage to materials. All of these disorders can be converted into financial losses that make much difference to a small business that needs to remain competitive in the market facing the giants while generating a profit that allows it to invest in their growth. Therefore, any unnecessary expense is exceedingly harmful and any savings already differentiates it from other companies of similar size. This study deals with the application of production engineering tools as 5S, kanban and layout in a building materials retail to tackle problems that prevent this company to have a stock organized and accurated. Finally, we recorded gains that the company reached with the implementation of part of the solution proposed

Citotoxicidade de cimentos retrobturados experimentais em fibroblastos V79: [recurso eletrônico]

Combining the characteristics of good adhesion and sealing of the AH Plus sealer the biological properties of the MTA, zinc oxide and calcium hydroxide, the purpose of this study was to evaluate the cytotoxicity of these associations. The specimens of the sealers and their associations were mixed and exposure to culture medium (82.4 mm2surface/mL) after the manipulation and incubated in a humidified incubator (37°C and 100% humidity) for 24 h. Chinese hamster lung fibroblasts (V79) were exposed to different dilutions of this extracts for 24 h and cell viability was measured by MTT test. The differences between the cell survival rates were statistically analyzed for Kruskal-Wallis and Dunn (p≤0.05). All sealers showed a significant difference with the group control, except the MTA. Cytotoxicity with the control group increased in the following order: AH Plus < AH Plus + Ca(OH) 2 < AH Plus + OxZn< AH Plus + MTA < MTA (p≤ 0,05). It was concluded that the addition of biological materials in order to improve the consistency of AH Plus for use in retro cavities its toxicity has not decreased significantly

Estudo do potencial de associações de ZnO com os produtos naturais ácido cafeico e ferúlico como filtros solares híbridos: [recurso eletrônico]

In this work were studied associations of ZnO with the natural products caffeic and feluric acids. Two preparation methods were used, that is, the sol-gel and a reflux procedure. In the sol-gel method, ZnO is produced by the basics hydrolysis of precursors in the presence of the organic filters (caffeic and feluric acids), which results in 30 nm (or less) ZnO particles with the organic filters (in dissociated form) bonded to the surface of ZnO. In the reflux method, a dispersion of ZnO in a water/ethanol mixture was kept under reflux (50oC/4h) in the presence of the organic acids. The ZnO particles used in the reflux method have a higher diameter than sol-gel ZnO particles, but the prepared associated product ZnO/Organic acids were similar. Despite of the difference in relation to crystallinity between the products, the preparation methods resulted in analogous associations with respect to the interaction of the organic filters with the ZnO surface. The caffeic/ZnO associations presented low photostability, which lead to the degradation of the organic filter. The other associations (feluric acid/ZnO) presented satisfactory results. The FT-IR spectroscopy confirmed the formation of the association, and the nature of the bond formed compared with the Zn-O bond in Zn2+/Felutic acid complexes. The isolated organic and inorganic filters, along with the associations were analyzed by diffuse reflectance spectroscopy and Uv-vis spectroscopy. The absorption edges and the critical wavelengths were analyzed and the effects of Zn-O bonds in feluric acid/ZnO associations described as a function of the relative position of the π/π* system of the organic filter. Finally the performance of the hybrid filters were investigated in terms of the absorption of UVA and UVB radiations, with the UVA/UVB ratio, an efficiency parameter largely used in the description of solar filters, sunscreen and suncare products

Avaliação in vitro da ação de substâncias químicas auxiliares, clorexidina e medicações intracanais sobre C. albicans, E. faecalis, E. coli e sua endotoxina em canais radiculares: [recurso eletrônico]

The purpose of this study was to evaluate the antimicrobial activity of chlorhexidine gel 2% as auxiliary chemical substance on the biomechanical preparation (BMP) and medication intracanal (ICM) on C. albicans, E. faecalis, E. coli and their endotoxin in root canals. We used 48 single-rooted human teeth divided into four groups according to dressing ICM: 1) Ca(OH)2 + pyrogen-free saline solution; 2) 2% chlorhexidine gel (CLX); 3) Ca(OH)2 + CLX, and; 4) pyrogen-free saline solution (control group). Were collected the contents of root canals to confirm the presence of microorganisms (confirmation), immediately after instrumentation (1st collection), after 7 days of the BMP (2nd collection), after 14 days of the action of ICM (3rd Collection) and 7 days after removal of the ICM (4 th collection). Were performed: the evaluation of antimicrobial activity and the content analysis of endotoxins for all sampling tests. The results were statistically analyzed using Kruskall-Wallis and Dunn tests with a significance of 5%. It was found that the CLX as auxiliary chemical substance has significantly reduced microorganisms confirmation collection when compared. In relation to the neutralization of endotoxin, it was found that the 1st and 2nd collections presented a decrease of 92.03% and 98.10% in mean percentage respectively, when compared to the confirmation collection. In the 3rd and 4th samplings, the Ca (OH)2 + CLX group showed the best results. It was concluded that the BMP and the ICM were able to eliminate the tested microrganisms, however, they were not able to completely eliminate endotoxins root canal

Gestão de estoque em uma empresa de varejo de produtos de limpeza e higiene pessoal

The deficiency in the product inventory management is common in small businesses, affecting several areas, especially the purchasing department that has difficulty in performing their tasks, acquiring the supplier's products at the time and in the most appropriate amount. Especially in the retail sector, the loss of quality of services is visible, because the availability of the product when there is demand is essential for the occurrence of sales and customer satisfaction. In this study, looking to improve inventory management in a retail company of cleaning products and personal hygiene, apply the classification method ABC (or Pareto Rule) to segment the available products. Thus are adopted buying criteria of new products based on the concepts of economic order quantity, safety stock and resupply point. The results show the feasibility of this procedure adopted because it was possible to propose an improved inventory management in a simple and effective way, contributing to company's competitive advantage

Exigências ambientais europeias: novos desafios competitivos para o complexo eletrônico brasileiro

The objective of this paper is to evaluate the implications of the european environmental requirements for electronic equipment on brazilian electronic industry sector. These deter-minations deal with elimination of hazardous substances and management of electronic products waste and have reached not only the electronic sector companies in international level, but brazilian electronic sector as well. Most brazilian companies of the electronic sector are getting complied with the requirement that restricts the use of hazardous substances. The main consequences of this process are technological innovations and changes on contractual relationships among companies. Foreign companies branches are more advanced than local ones in terms of timing of compliance to the new requirements and technological perfor-mance, showing an alignment with headquarter strategies. Not being complied with these requirements avoid companies to achieve commercial benefits and open space for questions about policies Brazil must take.
