The product portfólio management is considered relevant activity to the proper performance of the product development process. This paper aims to present the main methods of management that technology-based small businesses adopt for decision-making in product portfolio. This survey, which collected data on 31 companies was conducted. It was observed that although firms adopt market research and mapping methods and financial methods and for this decision-making, most of them based on the informal deliberations of senior management. Unable to understand the business relationships between the presence of ISO 9001 certification with greater formalization for decision making in product portfolio.

The use of pesticides to manage pest problems in agriculture has become a common practice around the world. Pesticides consist in chemical substances or biological agents that act preventing, destroying, repelling or mitigating the damage caused by pests in agriculture. In order to a successful treatment, the correct dosage of pesticide has to be applied for each kind of culture. In this context, this project aims to quantify the levels of the active ingredients Imidacloprid and Chlorpyrifos present in formulated technical products and compare with the reported in the ir commercial leaflets. The analyzes were performed by Ultra Performance Liquid Chromatography coupled to a photodiode array detector (CLUE-DAD). The identification of Imidacloprid and Chlorpyrifos in the samples was realized by comparison of the time of retention and UV spectre of those substances with the commercials patterns, resulting in a excellent method specificity of the method. In the scope of determination of active ingredients in formulated products, the method developed showed good sensitivity in the applied conditions, with suitables limits of detection (4,2.10-² mg L-¹ for Imidacloprid and 1,1.10-¹ mg L-¹ to Chlorpyrifos) and quantitation (1,4.10-¹ mg L-¹ and Imidacloprid 3,6.10-¹ mg L-¹ to Chlorpyrifos) for the concentrations found in matrices analyzed. Furthermore, good results were obtained to the method accuracy with coeficiente of variance values in the range of 0,6 to 0,7% for repeatability (intra-day) and 0,4 to 0,58% for intermediate precision (inter- day). The accuracy of the method was determined by recovery tests, the values were comprised in the range of 98 102%. According to the recommendations of the Associação Brasileira de Normas Técnicas, these values show good accuracy of the method. The concentrations obtained in the quantification of the active ingredients in formulated products showed values within permited by ABNT, 60.1% (w/v) ± 0.6%...

The identification of Salmonella spp. in food samples by microbiological diagnosis is time consuming, with approximately five different stages, requiring about 120 hours until the final result. The utilization of the polymerase chain reaction technique (PCR) can reduce this time, but substances present in samples may affect the reaction. The present work aimed to compare DNA extraction by thermic treatment and by the use of cetyltrimethil ammonium bromide (CTAB), in products originated from poultry houses corresponding to raw material (meat meal) and experimentally contaminated drag swabs. Materials obtained from the extractions were submitted to PCR, utilizing a pair of initiator oligonucleotides for amplification of Sdf 1 gene fragments. Comparing the methods of extraction, it was observed that when CTAB was employed, SE was detected in 70% of meat meal and in 80% of drag swabs, while the thermic treatment method yielded positive results in 20% of meat meal and in 40% of drag swabs. SE was detected under both methods utilized for DNA extraction, but the use of CTAB detected a greater number of positive samples, compared with thermal treatment.

In Brazil, the exploration and use of the Hevea brasiliensis Mull Arg. wood at the end of the latex production cycle from 30 to 35 years, is practically unknown. However, one of the most significant problems with its use relates to the high susceptibility of this species wood to the fungus Botryodiplodia theobromae attack, especially during the primary wood processing phase. The present study evaluated the efficacy of four chemicals to control juvenile and adult Hevea brasiliensis wood from the attack of the fungus stainer Botryodiplodia theobromae following the ASTM 4445 (2003) standard. The results showed that the active ingredients separately tested and evaluated in the laboratory; (Quinolinolato Copper - 8 and Carbendazim (T1); Tribromofenol 2-4-6 (T2); Extract-Based Vegetable Tannin (T3); Carbendazim and Prochloraz (T4)) do not totally prevent the contamination of Botryodiplodia theobromae in 5% level of significance

The collection of prices for basic goods supply is very important for the population, based on the collection and processing of these data the CLI (Cost Living Index) is calculated among others, helping consumers to shop more rationally and with a clearer view of each product impact of each product on their household budget, not only food, but also cleaning products and personal hygiene ones. Nowadays, the project of collection of prices for basic goods supply is conducted weekly in Botucatu - SP through a spreadsheet. The aim of this work was to develop a software which utilized mobile devices in the data collection and storage phase, concerning the basic goods supply in Botucatu -SP. This was created in order to eliminate the need of taking notes in paper spreadsheets, increasing efficiency and accelerating the data processing. This work utilized the world of mobile technology and development tools, through the platform".NET" - Compact Framework and programming language Visual Basic".NET" was used in the handheld phase, enabling to develop a system using techniques of object oriented programming, with higher speed and reliability in the codes writing. A HP Pavilion dv3 personal computer and an Eten glofish x500+ handheld computer were used. At the end of the software development, collection, data storing and processing in a report, the phase of in loco paper spreadsheets were eliminated and it was possible to verify that the whole process was faster, more consistent, safer, more efficient and the data were more available.
