Redução de desperdícios no serviço de atendimento ao consumidor: estudo de caso do orçamento base zero em uma empresa de linha branca

The self-evaluation is increasingly necessary in a competitive environment, and a way for companies to self-evaluate is through your budget. Knowing the importance of this budgetary process, this study aimed to observe and analyze the developing process of a zero-based budgeting (ZBB) highlighting its best practices and difficulties and propose recommendations for other companies in general. This goal was achieved through a case study in an area responsible for the budgeting process in the customer services department from a white-goods company. Also was required to review the literature regarding the customer services area, waste reduction, cost management, budgets in general and the zero-based budgeting. After reviewing the literature and the study, we can highlight good practices and difficulties observed in the studied company, and also propose recommendations on how to develop a zero-based budget and evidence what plans, analyzes and justifications are essential in a good budget process execution

Metodologia microbiológica convencional e reação em cadeia pela polimerase (PCR) na detecção de Salmonellasp. a partir de caldos de enriquecimento – Tetrathionato e Rappaport-Vassiliadis

The progressive increase in consumption and production of poultry meat in later years comes forth with an increase of the occurrence of foodborne diseases, including salmonellosis. Salmonellosis is caused by the ingestion of contaminated products, mainly by the consumption of poultry meat which processing and preparation for consumption were not effective to eliminate pathogens. Thus, there is a need for the development of faster more sensitive methods of detection of pathogens as a way to ensure the quality of the food offered to consumers. The goal of this essay was to evaluate the effect of enrichment broths on naturally contaminated poultry meat samples. A total of 65 samples was collected, these samples were rinsed with 370 mL of buffered peptone water (BPS) 1% according with the traditional methodology. All of the samples were enriched with both Tetrathionate (TT) and Rappaport-Vassiliadis (RV) and all were analyzed by the convencional identification method and polimerasis chain reaction (PCR). Of the 65 analized samples, 34 (52%) were positive when analized by the conventional method, while 45 (69%) were positive when analized by the PCR. Amongst the 45 positive PCR samples, 44 samples were positive when enriched with TT, while just 32 samples were positive when enriched by RV. Of the 34 positive conventional samples, 29 samples were positive when enriched by TT and 31 were positive when enriched by RV

Reação à variação ambiental em lebistes: o sexo importa?

Aqui mostramos que lebistes percebem modificações estruturais ambientais, mas que reagem a elas diferentemente quanto ao sexo. Vimos também que essas reações associam-se aos traços de personalidade de ousadia e hesitação. Os machos se locomoveram mais que as fêmeas e interagiram mais com objetos familiares. Porém, a introdução de objeto novo aumentou a interação das fêmeas com os objetos familiares. Além disso, machos e fêmeas interagiram mais com objeto familiar estruturalmente mais complexo comparado ao mais simples. No conjunto, esses dados indicam um perfil mais ousado dos machos e um perfil hesitante das fêmeas. Em todos os casos, as diferentes respostas de machos e fêmeas foram explicadas num contexto evolutivo adaptativo

Freqüência do parvovírus suíno em fetos mumificados, abortados e natimortos detectado através da reação em cadeia pela polimerase (PCR)

Porcine parvovirus (PPV) is associated with reproductive failure and it has been found worldwide, including Brazil. Many diagnostic procedures are used for its detection, for example, immunofluorescence, HA, HI and PCR and this is an important technique because it is very specific and sensitive. In this work, the presence of PPV in fetuses from swine farms with reproductive problems was detected by PCR. All of 170 samples from aborted fetuses, mummies or stillborns were sampled by PCR with primers designed to VP2 region of PPV and c-myc (endogenous control). Only 142 samples (83,53%) were positive for c-myc and among them six samples (4,22%) were positive for PPV which were tested in HA. In this test, erythrocytes suspension 1% was used and three samples (50%) agglutinated but they presented low titer (4). For this work, porcine parvovirus was detected in the samples analyzed by PCR and HA. It is important to emphasize the use of endogenous control when material with elevated degree of autolysis is examined

Métodos analíticos para a identificação de espécies animais

The food industry has been rapidly modernized, and with this the disposal and the consumption of industrialized food has been increasing continually. These products lose their original morphological characteristics, requiring fast and reliable tests that could help to identify the species in question, as most fraudulent behavior in the milk and dairy industry (meat and fish) is carried out where there is partial or total exchange of the original material for other with less value at market. Nowadays there is a lot of techniques that can be used for the identification of animal species, based on muscle protein, or DNA analysis. In the case of protein based analysis, we can mention several types of electrophoresis and immunologic methods, as ELISA. In the case of DNA based methods, we have several assays that use the amplification of DNA fragments, known as PCR, as proof. All these techniques have advantages and disadvantages that can be affected by factors- the sample condition, or the degree of relation between the species in question. Because of this, it’s necessary that a continuous study looking for the improvement of the available techniques, making sure that the confirmation of food authenticity is in place. This is to ensure the true product value, to comply with labeling regulationand and protect the consumer of frauds

A comunicação de empresas verdes e a relação com o consumidor consciente

This academic work has as its objective to demonstrate the fundamental role of communication as a tool towards implantating an environmental management project in organizations, aswell as familiarizing with the complex relashionship be-tween green businesses and its publics. The concern involving environmental prob-lems are increasing and it directly affects the consumer’s choice and their requests on organizations’ behavior. The integration with all sectors of economy is necessary as a part of a developing process that has as its main objective the environmental conservation and therefore the quality of human life on planet. There is also the question of how in the process of communication there is not an only way of interven-tion, but a continuous reciprocal action. The work is accomplished with an analyses of the green management communication of the business Grupo Abril

Estudo da reação de oxidação de metanol sobre fases intermetálicas ordenadas de AuIn, AuSn e AuSb2 em meio alcalino

The present work assessment materials can be used as fuel cells electrocatalysts. The alkaline fuel cell though was less studied, has some advantages compared to the acid configuration. The materials assesment were Au polycrystalline and intermetallics ordered phases of AuIn, AuSn and AuSb2. Your electrocatalytic properties were studied across cyclic voltametry and chronoamperometry techniques in Sodium Hydroxide 0,15M and Metanol 0,15M solution. The results obtained show a more efficiency to intermetallic AuIn as electrocatalyst for the oxidation reaction of methanol in alkaline medium, it showed high levels of current density and on set potential less positive compared to Au polycrystalline. The intermetallic AuSn showed activity just higher concentrations of methanol. Except AuSb2, who represented himself unstable in alkaline media, the intermetallics AuIn and AuSn present a promising future as anode materials for the oxidation in alkaline medium

Marcadores de superfície de Células-tronco: estudo de reação cruzada inter-espécies

Mesenchymal stem cells (MSCs) are adult multipotent cells with fibroblastoid morphology and adherent to plastic. Furthermore, they can be obtained from different sources. Besides bone marrow, these cells are taken from umbilical cord blood, umbilical vein, saphenous vein, peripheral blood, arteries, liver and fetal pancreas, placenta, dental pulp and adipose tissue. MSCs derived from adipose tissue are important because of the abundant number of cells that can be obtained from this tissue, easy access and little discomfort to the patient. This study compared two techniques for obtaining MSCs from adipose tissue: mechanical dissociation (MD) and enzymatic digestion (ED). We also analyzed the inter-species cross-reactions using commercial monoclonal antibodies directed against surface antigens of stem cells from different species: mouse, horse, rabbit, monkey and human. We found that MD technique is favorable in relation to ED within 15 days of culture, and ED is more efficient in the first days of culture. The data also showed that MD causes less damage to cellular DNA. About inter-species cross-reactions, the monoclonal antibody A69 directed against stem cells from rabbits, which can be used in veterinary medicine, particularly in research involving horses

Metodologia Microbiológica Convencional e Reação em Cadeia pela Polimerase (PCR) na detecção de Salmonella spp em carcaças de frango

Salmonella is the etiological agent responsible for one of the most important Food Borne Disease (FBD), Salmonellosis, which generates significant economic consequences in several countries, including Brazil. Poultry meat is one of the most important disseminators of the pathogen. Accordingly, several countries have developed programs trying to reduce the prevalence of Salmonella in poultry meat. Such programs are based on the research of the pathogen in the carcasses, establishing a maximum limit of positive samples at each set of analysis. The Salmonella scans are usually made using the conventional microbiological methods, which tend to be expensive and time consuming. In recent years were developed rapid methods such as polymerase chain reaction (PCR), which can greatly shorten the results time, showing greater sensitivity and specificity than conventional methodology

Confecção e caracterização de filmes finos de boro para a medida da taxa de reação 10B(N, a)7LI na terapia por captura de nêutrons pelo boro

The Boron Neutron Capture Therapy (BNCT), based on the 10B(n,α)7Li reaction, represents a promising modality for the treatment of cancers that are resistents to conventional treatments. So, it is necessary to find drugs (boron compounds) with high selectivity for each type of cancer, the neutrons source should be well characterized and the rate of 10B(n,α)7Li reaction should be measured with great accuracy as possible. This study aimed to develop a method for manufacturing thin films of boron, for measure the 10B(n,α)7Li reaction, and analyze the uniformity of the films. Five thin films of boron were manufactured with three different concentrations of boric acid, heated to transform the acid in boron, irradiated with thermic neutrons coupled to CR-39 detectors, in BNCT line at the reactor IEA-R1 IPEN/CNEN, São Paulo. After the irradiation, the detectors were chemically attacked with NaOH to reveal the tracks. The methodology presented is effective because it resulted in deposition of boron as thin film enabling the quantitative analysis of 10B(n,α)7Li reaction. The analysis of the uniformity of density of the induced tracks in CR-39 shows that, in most of the films, there is no uniformity in surface distribution of boron, but when the film is divided, we obtain some uniform sectors
