Non-specific chronic low back pain (NSCLBP) is considered one of the main complaints reported by the older people, leading to disability and decreased functional performance. The literature describes Pain Neuroscience Education (PNE) as an effective tool to modify beliefs and attitudes towards chronic pain, reducing kinesiophobia, pain intensity and disability when associated with exercises therapies. In the older people, Pilates Method (PM) exercises have been associated with improved kinesiophobia, pain intensity, disability, flexibility and balance. However, the effect of PNE associated with an exercise protocol in the older people is not yet known. Thus, this dissertation aimed to verify the efficacy of PNE associated with PM, compared to the PM, in kinesiophobia, pain intensity, flexibility, physical performance, mobility, functional balance and muscular electrical activity of the trunk extensor muscles in the older people with NSCLBP. Therefore, three studies were carried out. Study 1: "Effects of Pain Neuroscience Education associated to Pilates on kinesiophobia for older people with nonspecific chronic low back pain: protocol for a randomized controlled clinical trial". Objective: To describe the protocol used in a blinded randomized clinical trial, designed to combine PNE with PM as interventions for the treatment of NSCLBP in the elderly. METHODS: Eighty older people were randomly assigned to 2 groups (Education and Pilates Group - GEP and Pilates Group - GP), 40 people per group. Initially the GEP participated in 3 individual PNE sessions and then, the two groups participated in 16 Mat Pilates classes. A blind investigator evaluated kinesiophobia, pain intensity, flexibility, mobility and functional balance, physical performance and the electrical activity of the trunk extensor muscles before and after the interventions. Study 2: "The Effects of Pain Neuroscience Education and Pilates on Kinesiophobia in the older people with Non-Specific Chronic Low Back Pain: Randomized Controlled Clinical Study." Objective: To verify the efficacy of PNE associated to PM, compared to PM only, in improving kinesiophobia, pain intensity, flexibility, physical performance, mobility and functional balance of older people with NSCLBP. Results: There was no significant difference between groups in the studied variables. Conclusion: PNE was not effective in adding positive effects to PM practice in older people patients with NSCLBP, but it was effective in helping older people patients to adhere to exercise treatment. Study 3: "The Influence of Pain Neuroscience Education and Pilates on the muscular electrical activity of the older people with non-specific chronic low back pain". Objective: to evaluate if the PNE intervention associated with the PM exercises can alter the electrical activity of the trunk extensor muscles in functional tasks in the older people with NSCLBP. Results: there was a statistical difference between the groups, with a decrease in the electrical activity of the GEP after the intervention in the task of reaching in the amplitude and peak of the right longissimus muscle and amplitude of the left iliocostalis muscle. Conclusion: The association of END to PM exercises decreased the electrical activity of the right longissimus and left iliocostalis muscles, with maintenance in the performance in the reach task.

This research aims to analyze some stories by the Angolan fiction writer João Melo, focusing on (in)visible subjects included in the pariah category (VARIKAS, 2014). Being one of the singular cases in the African Literature of Portuguese Language, the writer published poetic works and has been emphasizing like a representative author of short stories, with plots related to social conflicts, as well as the ones of gender, besides weaving a critical reflection on political and historical aspects of Angola. The research will focus on the following short stories ―O discurso da beleza‖, ―O criador e a criatura‖ and ―Maria‖. We are interested in investigating in the texts the aspects of the fictional representation of essentially politicalsocial themes, such as the clash with chauvinism, violence and the lack of identity of the country, generating suffering and conflicts. Throughout the analyzes, we will try to verify to what extent these aspects contribute to the identity construction of the Angolan subject.

In view of legal requirements that aim at improving quality of cost information by all federal departments and the complexity of calculating costs in public institutions, the present study investigated process of structuring cost information in the School Health Unit (SHU) of Federal University of São Carlos, the costing investigation process and the utilization, or not, of information systems in the scope of the university. The research is characterized by the integration of quantitative and qualitative information, in the form of a case study - according to the objectives it is classified as descriptive and exploratory. The multiple sources of evidence used for data collection enabled the identification and mapping of items consumed directly and indirectly by SHU, and according to the cost structure by absorption, the general unit costs were calculated. Using database information’s, the full financial cost of SHU was calculated and the representativity of each item and its group was identified, evidencing the participation of information systems used by the institution in the construction of cost information. It was found that the existing costs in the SHU are predominantly permanent, where the prevalence of certain groups of expenses was verified. The cost of the expense groups, salaries, personnel benefits and social taxes, represents almost 80% of the total cost in SHU. Permanent costs bring limitations to managers at any level of decision, because oftenly, they cannot be avoided and because they are costs related to legal obligations, as is the case of costs with effective servers. Regarding the information systems in the calculation of cost, it was verified that the generation of cost information for the object in study was only possible with the predominant use of manual control, once that most of informations was provided by Excel spreadsheets, which directly affects the reliability and quality of informations. Existing data in the information systems used by the University require adaptations and systemic integrations to then, offer cost information at the departmental level.

The patrimonial assets of the historic farms from São Paulo are rich sources of knowledge, impregnated with symbolic values, and represent the trajectory of the constituted power over time and the process of society. In order to facilitate the access to these assets, some public policy projects funded by FAPESP were developed: "Virtual Memory of São Carlos" (2004- 2008), "Cultural Patrimony of the State of São Paulo: Privileged Space for Research, Education and Tourism "(2008-2012) and" Criteria and methodologies for conducting an inventory of the rural cultural patrimony of São Paulo "(2012-2014). These projects resulted in two important products: the Information Description Standard, which allows the exhaustive cataloging of any type of property, and the Virtual Memory system, a web system composed of two subsystems, one for cataloging and one for access and navigation. The purpose of the present work is to create a prototype of a semi-functional interface for user, called InfoMinerva, to access data contained in the Virtual Memory web system, considering the premises of authors of the field of human-computer interaction. The target public considered to use the interface is composed of researchers and interested in patrimonial assets, not being prerequisite high level of knowledge in computer science. The study, initially exploratory, reviewed the literature on themes: historical patrimony, historical heritage in digital environments, human-computer interaction, quality and interaction criteria and principles, guidelines and heuristics aimed at the development of interfaces. By nature it is an applied research for proposing a solution for the availability of assets through the internet, relying on the prototyping technique. The first prototype, of low fidelity, was created on paper, which established the main elements of the interface, except colors, shapes, fonts, and the expected behavior at the time of interaction with the user. The evaluation of this stage took place in a formative way, through the guidelines of Nielsen and Tahir, making possible the correction of possible faults before the development of the interface in digital media. The second prototype, of high fidelity and semi-functional structure, was made using the Wix site creation platform, in which the elements designed in the first stage were applied, including colors, shapes and fonts. This step was evaluated through mixed questionnaires, adapted from the Questionnaire for user interaction satisfaction, and delivered to two groups of users: the first, made up of information professionals, information technology professionals and professionals in the area of historical heritage, and the second, of potential users. The analysis of the questionnaires, using statistical techniques (Likert scale, arithmetic mean, fashion, sample variance, standard deviation and Cronbach's alpha), showed that the general objective of the research was achieved, and the necessary interventions are mainly related to accessibility and responsive design.

The segmentation of the hippocampus in Magnetic Resonance images is an important procedure in the Alzheimer’s disease early diagnostic aid. The neuroradiologist frequently needs, in addition to the atrophy analysis, to know the volume of the hippocampus for an accurate diagnosis or even perform the monitoring of some treatment. However, the segmentation of the hippocampus performed manually by a specialist is time-consuming and subject to the inter- and intra-operator variability of the measures, for this reason, methods for automatic segmentation has been an object of study for the scientific community. Among the several proposed methods, those using anatomical atlases and deformable models present better results. These two types of techniques easily embedding the format of the models in the segmentation process, but are highly dependent on the initial positioning of the models. In this work we used 3D salient points, detected in MR images using the 3D Scale-Invariant Feature Transform (3D-SIFT), for the positioning of deformable geometric models, representative of the hippocampus. The results indicate an 11% improvement over the exclusive use of affine transformation, 30% over 3D-SIFT without any modifications and 7% over non-weighted positioning.

The Internet of Things allowed the creation of a set of computer systems embedded in everyday objects such as clothes, toys and home appliances. Some of these systems are not just for use but offer possibilities for customization through programming. However, especially for specific audiences, such as small children (4 to 6 years), this universe of differentiated interactions, in which different intelligent devices with particular specifications coexist, may require greater cognitive effort, making it difficult to use programming functionalities. In this scenario, this work presents an interaction model to guide the provision of programming devices for children. For the construction of this model, specified and represented in the Stamper´s Semiotic Ladder, a state-of-the-art survey was performed on the programming of physical devices by infants in early childhood and a case study using Participatory Design techniques with the participation of children between 4 and 6 years old. A feasibility study conducted with a paper-based prototype indicated that children can control devices from programming environments built following the model.

Sustainability is a subject that has gained visibility through international discussions and concern for the future. When talking about sustainability, it must be understood in terms of both environmental and social and economic aspects, emphasizing its scope. Computational solutions are consumer goods and herefore it is the responsibility of the software and hardware industry, as well as its designers and developers, to reflect and act so that computer solutions are aware of sustainability issues. The literature exposes everal works in the line of sustainable design, authors such as Blevis, Baranauskas and Fallman discuss the theme, however few are dealing with sustainability in design, and in particular computing is still in the first steps. Therefore, a set of recommendations was formalized to guide the designers of computational solutions in the creation of these solutions, so that the aspects of sustainability in design are already considered. The methodology adopted includes bibliographical studies, a questionnaire on the subject applied to the computer community, a diagram of affinities and a look at other areas of knowledge that already have consolidated methods on sustainability; such as ISO standards; for the construction of the guidelines. After creation, the guidelines were applied to the academic and business scenario. The evaluation of the resulting solutions occurred by one method; the product of a master’s degree dissertation in the same area of study, and the evaluation of three experts by the guidelines applied, which was satisfactory and generally changed the opinion of the people who participated in the study. With the help of guidelines, it is possible to think about how to design sustainable solutions that respect the continuity of life.

This paper identifies the perceptions of chemistry teachers working in high school in regular classrooms and teachers in initial formation regarding the process of conceptualization in Chemistry by students with visual impairment The process of conceptualization refers to the act or effect of conceptualizing, that is, the formation of a concept based on the specificity of Chemistry as Science. Several papers report on the great challenges of teaching concepts and scientific phenomena for students with visual impairment, but they are directed to the teaching of Physics, existing a lack of proposals of teaching chemistry for this public, in an inclusive reality. The data were obtained through questionnaires with closed and open questions, wich was made available both printed and online and counted on the collaboration of 168 informants, who were separated into three groups, being: 73 professors graduated in chemistry; 70 teachers in initial training who were pursuing a degree in chemistry; and 25 with other formations. The data were analyzed by mixed methodology (qualitative and quantitative) using Content Analysis, with the aid of NVivo software, through categorization of responses. The quantitative analysis was performed with the IRAMUTEQ software, using Textual Statistical Analysis, with the method of analysis of Hierarchical Descending Classification (CHD) and analysis by similarity. The results showed that most of the participants believe that it is possible to teach concepts and chemical phenomena to students with visual impairment, but pointed out difficulties that go through this process, such as: the need of teacher training; elaboration of special resources, necessary methodologies to meet needs, working conditions of teachers, experimental adaptations, in which, often, phenomena are explained from visual observations, and application of the 3 dimensions of the specificity of the teaching of Chemistry, being the theoretical, phenomenological and representational levels.

The work described here aimed at the design of an inductive heating oven using a new methodology, by using a natural oscillating circuit that, by means of an induction coil, generates the magnetic field that will heat the inserted workpiece inside. The workpiece adopted for the heat treatment in this work is a carbon steel alloy known as Steel 5160. For the construction of the system, the dependence of the metal composition on the heating temperature and the behavior of the induced eddy currents were taken into account. This work presents: the circuit topology used; the proposed design methodology; the design of the induction coil, where the shape, number of turns and the space between the coil and the part are essential for efficient system operation; the heating curve obtained through the complete tempering of the end of a key and a nail, and the efficiency of the system, making a quick comparison of the results obtained in relation to other research. The final prototype assembled was low-cost; low complexity and high versatility.

The aim of this article is to analyze the relevance of dystopias in the critique to authoritarianism present in the novel Incident in Antares written by Érico Veríssimo. After presenting the main characteristics of utopian thought and dystopia as a literary genre, we investigate how Veríssimo denounced through his dystopian society the deepest contradictions of a country historically plagued by coups d’état and military dictatorships. The article also aims to demonstrate how prevailing Veríssimo’s criticism is, especially regarding to the permanence of authoritarian thought, social inequalities and violations of human rights in Brazil.

As instituições e as agências de pesquisa vêm exigindo uma conduta no contexto da agenda em prol da Ciência Aberta. Sendo que, a elaboração de um Plano de Gestão de Dados pode ser caracterizada como um procedimento inicial para o desenvolvimento da pesquisa científica, documento que propõe ao pesquisador gerenciar os dados brutos de sua pesquisa, valorizando o compartilhamento em conjunto com a abertura dos dados e seu reuso em benefício aos pesquisadores e à sociedade. Diante disso, o objetivo desse trabalho foi verificar a elaboração de um Plano de Gestão de Dados como parte das novas condutas para as boas práticas na pesquisa científica. A pesquisa caracterizou-se como exploratória, empregou-se métodos documentais e bibliográficos para a identificação, coleta e sistematização das informações. Os resultados visaram a disponibilidade desse documento em repositórios de dados abertos e a relação das instituições de ensino superior, agências financiadoras e pesquisadores com o levantamento de ações que são realizadas na criação e desenvolvimento de Plano de Gestão de Dados, principalmente para o desenvolvimento de políticas institucionais para o gerenciamento dos dados de pesquisa, porém, respeitando também as áreas do conhecimento, visto que nem todos os dados são gerados do mesmo modo. Por fim, considera-se a presença de um novo paradigma na publicação e divulgação científica, o que influencia também sua comunicação, seja com o meio acadêmico ou com a sociedade.

With the longevity of the population increases the prevalence of cognitive alterations in the elderly at the same time that the nutritional state also undergoes changes. The objective of this research was to verify cognitive factors associated to the poor nutritional status of the elderly attended in the primary health care services of a city in the interior of São Paulo. This is a cross-sectional study, with descriptive, correlational and association analyzes performed with a sample composed of 234 participants. The data were collected in the homes of the elderly and were used: Instrument of sociodemographic characterization, Mini Evaluation of the Nutritional State-MAN, Addenbrooke-ACE-R Cognitive Exam, and International Questionnaire of Physical Activity - IPaq. The results showed that the majority of the sample consisted of women (67.9%), with a mean age of 69.55 years, married or living with partners (59.4%). The majority of the elderly evaluated presented signs of cognitive impairment (54.3%) and adequate nutritional status (85.5%). Older people with inadequate nutritional status (malnourished or at risk of malnutrition) presented worse performance in the cognitive evaluation, when compared with the elderly with adequate nutritional status. There was a positive correlation between MAN scores and cognitive tests (ACE-R total: 0.339; r <0.001; Attention and Guidance: 0.220; r = 0.001; Memory: 0.333; r <0.001; Verbal Fluency: 0.268; <0.001; Language: 0.258; r <0.001; Visuo-spatial: 0.278; r <0.001). Among the factors associated with nutritional status, the analyzes showed that global cognitive performance (p = 0.001) and all cognitive domains: Attention and Guidance (p = 0.001), Memory (p = 0.002), Verbal Fluency ), language (p = 0.008) and visuospatial ability (p <0.001) were positively associated with nutritional status. Insufficient practice of physical activity and use of more medications were negatively associated with nutritional status. It is concluded, therefore, that the cognitive performance is correlated to the nutritional state, being that the global cognitive performance and the specific domains present as protective factors to the nutritional state.

In this work we study the quadruple perovskite structure manganese oxides NaMn7O12 and LaMn7O12 under the point of view of multiferroicity, magnetoelectric coupling, and also structure anomalies on NaMn7O12. These studies range from the existence to the mechanism of the establishment of multiferroicity and coupling between ferroic orders in these materials. The driving force of the dynamic structural anomalies in NaMn7O12 are also studied with the goal of clarifying the mechanisms of structural distortion and how they relate to the onset of ferroic orders. The results of IXS and DXS experiments show interesting dynamical anomalies in NaMn7O12's structural transition, a softened phonon at the structural modulation wavevector that was shown to be related to diffuse x-ray peaks with a different wavevector point in the direction of competing distortions and that the Jahn-Teller mechanism driven distortion overcome its competitor. A ferroelectric transition was found simultaneous to anomalies in specific heat and magnetization in NaMn7O12. Magnetic hysteresis loops are quite wider in the ferroelectric phase. These properties are explained in function of a magnetoelectricity mediated antiferromagnetic domain wall ordering model. As for LaMn7O12, a ferroelectric transition at the B site antiferromagnetic transition temperature. Besides the particularities of each system, structural and magnetic properties imply that their ferroelectricity is of magnetic origin through the exchange striction mechanism.

Chitosan is a biopolymer widely used in agriculture and in the food, medical and pharmaceutical industries. It is obtained by the deacetylation of chitin, extracted from the carapace of crustaceans or fungal mycelia. Despite its potential as an antimicrobial agent, chitosan is still not used in the bioethanol industry to control process contaminant yeasts. Dekkera bruxellensis is an opportunistic yeast of great interest to the wine industry and fermentation processes for ethanol production in Brazil, and its control becomes necessary. In this context, the objective of this work was to obtain chitosan from shrimp residues by bacterial fermentation and subsequent chemical deacetylation and to evaluate its inhibitory effect on yeasts from bioethanol production. The bacterial fermentation was carried out in optimized concentrations of residue, inoculum and glucose aiming at higher production of acids. The chitin deacetylation process to obtain chitosan was done by the autoclave method, at 121 oC and 1 atm, using 45% sodium hydroxide. Chitin and chitosan obtained were characterized by infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential thermal analysis (TG-DTA) and differential scanning calorimetry (DSC). The effect of the obtained chitosan (natural) and a commercial chitosan on the growth of D. bruxellensis and an industrial strain of Saccharomyces cerevisiae (PE-2) was evaluated in sugar cane broth and YPD culture medium. The effect of adding 500 mg/L of natural chitosan to the fermentation in sugar cane broth in co-cultivation with D. bruxellensis was also evaluated. In the chitin extraction by lactic fermentation step, the conditions of higher acid production were 10% (v/v) inoculum of L. plantarum and 100 g / L of glucose. At the concentration of 5% (m/v) residue, the best results were obtained in the fermentation to obtain chitin, producing 23.09 g of lactic acid / 100 mL. The demineralization rate was 77% and deproteinization was 43%. Infrared spectra (FTIR) confirmed the presence of chitin and chitosan in the samples after fermentation and after deacetylation respectively, with 80% deacetylation degree. X-ray diffractograms showed the crystallinity profile of the samples, with chitin being more crystalline. Thermogravimetric analysis showed higher thermal stability of natural chitosan compared to commercial chitosan. Both commercial chitosan and natural chitosan reduced the maximum specific growth rate (μmax) of both yeasts and caused an increase in the lag phase of D. bruxellensis in 6 and 3.5 hours, respectively, at the concentration of 500 mg / L. The same was not observed in S. cerevisiae. This concentration of natural chitosan when added to the fermentation reduced the number of D. bruxellensis in approximately 1 log cycle after 12 hours, with minor effect in S. cerevisiae population. The fermentative efficiency was 22% higher when compared to the fermentation without chitosan. The natural chitosan obtained under the conditions of this work presents as potential antimicrobial to be used in the fermentation for the production of ethanol fuel to control the contaminating yeast D. bruxellensis, without interference in the process.

Background: The investment in acceleration sensor-based equipment as a fall prevention strategy can represent a viable option for the monitoring of the fall risk. However, more studies are needed on the analysis of such data, in particular for the prediction of future falls to be adopted for health care and prevention. Thus, the objective of this study is to investigate patterns for fall risk screening in the elderly with no recent history of fall, through three types of Timed Up and Go (TUG) tests using a single acceleration sensor. Methods: A prospective study was conducted with 74 healthy elderly non-fallers using waist acceleration sensors while performing three variations of the TUG. After evaluation at baseline, the occurrence of falls (outcome) was monitored quarterly during one year. We investigate frequency features extracted from the accelerometry signal and their ability to predict falls. Mann-Whitney U test was used to compare the groups. Besides, analyze of accuracy, sensitivity and specificity were performed. Results and Discussion: The best individual feature result shows an accuracy of 0.75, sensitivity of 0.71 and specificity of 0.76. A fusion of the three best features increases the sensitivity to 0.86. Statistical difference was found in the whole accelerometry data, without any type of processing, for three, six, nine and twelve months of follow-up. The cut-off points of the TUG seconds did not demonstrate adequate sensitivity for community-dwelling elderly. Conclusions: The results confirms previous evidence that accelerometer features can better fall risk, and support potential applications that try to infer falls risk in less restricted scenarios, even in a sample stratified by age and gender composed of active community-dwelling elderly.

Objective: to construct and validate a protocol for the nursing care of the patient in the transoperative period of cardiopulmonary bypass with cardiopulmonary bypass (CPB). Method: methodological, quantitative study, developed in two stages referring to the construction and validation of the content of the protocol. The validation was performed using the Delphi technique in two rounds, with the participation of 14 experts as evaluators of each variable proposed in the protocol. The selection of experts was by snowball sampling. The items included in the instrument were evaluated using the Likert scale, with categories in four levels of importance and the selection of a single response for each analyzed variable, and by the analysis of the content of the instrument with the universal agreement of the index of content validity ( UA-IVC) and the Content Validity Index (CVI). Results: items related to surgical and patient room preparation, intraoperative care and report (intraoperative information) for the ICU were validated. The items obtained a mean score of 90% and UA-IVC concordance of 89%, in which eight items reached the 100% IVC and one the 93% IVC item; however, one item did not reach the IVC ≥80% being recommended the merger together with another item. Conclusion: the results of this study reflect the importance of the nurse's role in the implementation of a protocol with the purpose of guiding safe surgery practices that promote patient safety and effective communication within the context of cardiovascular surgeries.

Objective: To compare the effectiveness of conventional dressings and / or sutures with cyanoacrylate coatings for the reduction of mediastinitis rates in cardiothoracic surgeries. Methods: Systematic review of the literature conducted according to the recommendations of the Cochrane Handbook. The PRISMA protocol was used as a guide for the systematic review. We searched for randomized controlled trials with no limitations on language and year of publication in the following databases: Latin American and Caribbean Literature in Health Sciences (LILACS), Medical Literature Analysis and Retrieval System (Medline), Cumulative Index to Nursing and Allied Health Literature (CINAHL), National Library of Medicine (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), Virtual Health Library (VHL), Web of Science, Science Direct, Central Cochrane Library and Repository of Gray Literature using the controlled and uncontrolled descriptors. It was also searched in the gray literature, in ANAIS of Congresses, in specific bases on the studied subject and in the references of the references with the purpose of exhausting the literature. Prior to the data analysis, a bias risk control form was used. Results: Four studies (2092 participants) aged 45 to 81 years who used cyanoacrylate in sternotomies were included in order to reduce mediastinitis rates. The studies were consistent with the proposed outcomes and presented a low risk of bias in the areas of the Cochrane Collaboration bias risk table except in the areas of secrecy and masking, since the studies involved surgical procedures. The selected studies responded to the primary outcome of this study, namely reduction of mediastinitis index with the use of cyanoacrylate, but did not respond to proposed secondary outcomes that were reduced hospitalization time and reduced treatment costs. Conclusions: The use of cyanoacrylate based coatings is equivalent to traditional skin preparation in cardiac surgeries, as it does not significantly influence the incidence of Surgical Site Infection (ISC). However, the use of cyanoacrylate decreased the incidence of SSI in groups more prone to infection, namely: elderly patients with chronic diseases (systemic arterial hypertension, Diabetes Mellitus or vascular diseases) and obese patients.

In this work two electrochemical sensors were proposed based on carbon nanomaterials for detection of diquat and tadalafil. For the first was proposed a surface modification of glassy carbon electrode with manioc starch and nanodiamonds dispersion. The other sensor was based on a film of vertically aligned carbon nanotubes with a copper plate like substrate. The glassy carbon electrode modified with nanodiamonds and manioc starch film was characterized electrochemical and morphological characteristics through techniques such as cyclic voltammetry, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy and x-ray diffraction to understand the electrochemical behavior of the film. Many techniques were analyzed regarding the behavior and quantification of diquat, however, the technique that presented the highest peak current was the square wave voltammetry. After the choice of chemical and electrochemical parameters, was constructed an analytical curve with a linear range of 5.0×10−7 to 4.6×10−5 mol L −1. The limit of detection was 1.1×10−7 mol L− 1. Water samples fortified with diquat were analyzed. In comparison to the works, the glassy carbon electrode modified with nanodiamonds and manioc starch film has a good linear range and a low limit of detection. For the second electrode was chosen for morphological characterization through images obtained by scanning electron microscopy, as well as transmission; in addition to electrochemical characterizations acquired by cyclic voltammetry from the potassium ferri/ferro-cyanide like redox probe. In order to study the electrochemistry of tadalafil were analyzed some voltammetric techniques like cyclic voltammetry, linear sweep voltammetry, differential pulse voltammetry and square wave voltammetry, especially the linear sweep voltammetry in which the device reached the highest anodic peak current. Optimizing the parameters, the analytical determination of tadalafil comprised a linear concentration range of 0.85 to 8.9×10−6 mol L−1 where the limit of detection was 7.8×10−8 mol L−1. The samples selected for validation of the device were drugs obtained from pharmacies in the city of Araras being a generic and a manipulated drug.

It is alarming the speed with which the elderly population has been growing in recent years. Faced with this undeniable phenomenon, urban space has an increasing concentration of elderly. In this context, problems are intensifying and socio-spatial inequalities reduce the possibilities of achieving the right to adequate housing. Attentive to this question, the World Health Organization has launched in 2007 the "Global Age-friendly Cities: A Guide", which advocates actions based on eight main axes, in favor of accessible and coherent urban planning for the aging of the population. Thus, this research aimed to analyze the habitability conditions and the functional capacity of the residents of two exclusive condominiums for the elderly: Vila Dignidade and Recanto Feliz, both implemented through public policies for low income elderly people in the city of Araraquara-SP. This is a transversal, descriptive research based on the assumptions of the quanti-qualitative method, with exploratory fieldwork, through visits to housing estates, with the application of the following instruments: the Vancouver Protocol, same resource used in the development of the Global Guide Age-Friendly Cities and the BOMFAQ questionnaire to check participants' levels of independence. The quantitative data were analyzed by means of simple descriptive statistics and the qualitative ones, in the light of the theoretical reference. Were interviewed 40 residents (24 from Recanto Feliz and 16 from Vila Dignidade). As to functional capacity, it was found that Recanto Feliz elderly presented less functional impairment than those of Vila Dignidade. Regarding the analysis of the eight axes of the Vancouver Protocol, the location of the condominiums had an impact on the residents' perception of the city of Araraquara, but Vila Dignidade interviewees were more satisfied than Recanto Feliz, except in relation to their homes. Regarding accessibility conditions, it was identified aspects to be improved in both condominiums, internally, regarding the need for physical adaptations of Vila Dignidade housings, and externally, regarding the importance of improving the infrastructure in the Neighborhood Unit of Recanto Feliz. The results obtained, combined with the theoretical development developed in this study, provided support for the interpretation of what represents adequate housing and how much this aspect influences the quality of life of the elderly person, and consequently, the capacity to enjoy the urban space.
