Our object of study is a videoclasses service (videoaula@rnp) over the Internet, maintained by the National Network of Education and Research (RNP). To approach it will use the Actor- Network Theory. We propose here to look at the crossings between software, public officials and laboratories. The software available for publishing videoclasses by RNP is a Free Software called RIOComposer. This has become a link between free software and distance education. Obviously, this link is not given in a simple way and involves, on our part, a study of the Free Software and the RNP. Besides that, the movement of some laboratories involved with the creation of RIOComposer and other solutions for distance education will be observed. We will monitor the principles that guided the first Free Software developers, as their initial consequences. For that, some authors of social sciences, who proposed to examine the Free Software, will be used. About RNP, we will deal with its various initiatives involving the spread of high-speed networks for the Brazilian academic community and the development of solutions in Information and Communication Technologies. The selected laboratories will be seen in its relations with the Free Software and RNP.

Currently higher education institutions are under pressure given to the current demand for innovation of their efforts, not only in the context of research, but also in relation to education. The technological context for the insertion of digital technologies as a way to improve teaching and learning contents, procedures and attitudes are increasingly promising with the possibility of making them more suited to the reality that surrounds students. However, how teachers have appropriated these technologies for teaching in order to help their students in the construction of knowledge? Facing this question, this paper aims to investigate how music teachers of a higher education federal public institution utilize an electronic educational game as a music education tool. This work also falls within the framework of the discussions on how teacher training deals with Digital Technologies of Information and Communication, proposing an investigation of how these technologies are presented or taught during the process of teacher training, both in initial training and continued education proposals. The research methodology's focus is qualitative and descriptive. Data collection was based on empirical sources obtained from semi-structured interviews with music education teachers working in higher education at the Federal University of São Carlos (UFSCar). In addition to the analysis of data from the interviews, it was also intended to follow practical applications of the educational game Musikinésia, which could be explored into the keyboard classes of Bachelor of Music course from UFSCar as a resource that helps the students to learn the instrument keys. The results of these applications showed that, in fact, a game can bring learning benefits to students, however, it was also witnessed some difficulty by teachers in dealing with this technology, which alerts us to rethink how the preparation courses degree are training future teachers to think critically when it comes to digital technologies.

The woman´s access to higher education and academic career is na achievement. More and more women occupy the graduation chairs, getting to many areas of knowledge, occupying more than half of the places offered. But the number of women found in the highest scientific career positions remains low. What happened along this career path that prevents women able to ascend vertically? The glass ceiling assumption seems to define the force that keeps women in lower hierarchical positions. The glass ceiling is formed not by one, but by many barriers and obstacles that add up acting often in the loss of women throughout their careers. This work seeks to understand a little of the professional lives of researches who managed to get to a privileged elite of science, the "National Counsel of Technological and Scientific Development" – CNPq grant recipients in research, with the intention to diagnose the nature and impact of gender differences throughout the scientific career. From this point is possible to draw up suggestions for actions that seek to provide an institutional environment with equal opportunities for both genders.

Counting the number of leukocytes present in the blood vessels is an important task to understand inflammation mechanisms and to assess the effects of drugs that are being developed for the treatment of inflammatory diseases. In general, leukocyte counting is done by an observer (laboratory technician or specialist) using a sequence of intravital microscopy images obtained from blood vessel of an animal testing. However, this procedure is time-consuming, prone to errors, due to visual fatigue of the observer, and biased, due to inter and intra-observer variability. Thus, the objective of this work was the development of computational technique for the automatic detection of leukocytes in intravital video microscopy images. For this, the detection of leukocytes was performed in two main stages. In stage 1, the phase congruency measure, which is invariant to changes of contrast and lighting images, was used to calculate a blobness measure used to detect circular structures in intravital microscopy images. In stage 2, the circular structures detected in stage 1 were analyzed locally to identify only those corresponding to true leukocytes. The results were evaluated using the precision, recall and F1-measure metrics and the area under the precision-recall curves. Furthermore, the proposed technique was compared with the template matching technique.

We study fractal subordinacy theory for one-dimensional Schrödinger operators. First, we review results on Hausdorff subordinacy for discrete one-dimensional Schrödinger operators in order to analyze the differences and similarities of these results with respect to the packing setting. By using methods of packing subordinacy, we have obtained pac- king continuity properties of spectral measures of such operators. Then, we apply these methods to Sturmian operators with rotation number of quasibounded density to show that they have purely α-packing continuous spectrum. Moreover, we show that spectral fractal dimensional properties of discrete Schrödinger operators with Sturmian potentials of bounded density and with sparse potentials are preserved under suitable polynomial decaying perturbations, when the spectrum of these perturbed operators have some singular continuous component. Finally, we performed an introductory study of fractal subordinacy for continuous one-dimensional Schrödinger operators defined in bounded intervals.

Global phenomena such as population aging, increased rate of disability, and growing numbers of obese people have gained intense attention within the air transportation industry since it expects increases in travel and changes in the profile of users. However, studies have indicated gaps between the needs of passengers and the services and assistance provided by airlines and airports. Therefore, the objective of this study was to understand the contradictions and discontinuities in the activity systems of passengers with disability, elderly and obese in the Brazilian air transportation originating restrictions to participation during the flight and during the boarding and deplaning process of air travel. In the present study, a qualitative approach was adopted based on Ergonomics and the Activity Theory. The research participants were passengers with physical, visual, and auditory disabilities and elderly and obese passengers. A combination of methods and techniques was used for data collection, including: 14 preliminary interviews in health care organizations and facilities that provide assistance and services for the participant groups and air transportation users, with a total of 25 participants; a questionnaire survey involving 399 respondents; and observations in commercial aviation. A total of 43 non-participant observations were carried out, and other eight participant observations took place during the journey, which included two self-confrontation interviews. The results indicated passenger participation restrictions during the journey affect attitudinal barriers and limited spatial accessibility that are related to airport infrastructure, airport signs, operational factors, equipment, aircrafts, and regulatory aspects. These restrictions are related to contradictions in the interaction of the components of activity system, which include: the passenger, the artifacts, the rules, the community (passengers and workers), the airport operators, and the airlines, and the object of the activity. It was found that, in order to face these difficulties, passengers employ personal and interpersonal strategies. Therefore, specifications were developed to change the contextual factors associated with the environment, equipment, and operations. To promote full participation during the air journey, some changes are needed; primarily transformation in significance and representations for action of people involved in the air transportation and their work activity, seeking to achieve integration between design and use. This study was carried out focusing on the activity, which contributed to the involvement of different social actors; thus the information provided is based on the learning gained from experience and interaction with the subjects and the context aiming to demonstrate the users’ needs and constraints and support new air transport developments.

This Master's degree research aims to analyze the perception, reception and evaluation of students and the teacher-researcher regarding activities employed from the perspective of Critical Literacies. Theoretical aspects are based on authors like Monte Mór (2008, 2014, 2015), Lankshear and Knobel (2003, 2007), Duboc (2012, 2014), Duboc and Gattolin (2015), Kalantzis and Cope (2008, 2012), Rojo (2009, 2012), Janks (2012, 2013), Janks and Vasquez (2011), Freire (2011), Cervetti et. alii. (2001) and Jordão (2010; 2014), who report the possibility of developing critical features and agency of individuals accounting for the local context. Besides, we seek for understanding considerations about the post-method through Kumaravadivelu (2006) and Abrahão (2009) in order to analyze participants' autonomy development and issues related to teaching practices. Furthermore, we search to find focal points between the two perspectives mentioned before. Considering the qualitative nature of this study, it is under the methodology of a research-action according to Burns (1999; 2010) and Viana (2007), as it takes place in an environment in which the teacher rethinks her practice. The tools used were: survey, aiming to profile and understand the interests of students; the record book of the teacher-researcher, self-evaluation sheets and audio recording of the lessons. These tools enable us to observe the perception of the participants about teaching units, the progress of activities, the attitude of the teacher-researcher, the gaps that took place in the classroom and the curricular attitude of the teacher-researcher before these gaps. The research was carried out at a State Language Study Center, in the state of São Paulo, located in a public school in a small town in the countryside. The organization and analysis of data allowed a reading which indicates the strategies used by the teacher-researcher to improve Critical Literacies and we observe: a) material elaboration; b) perception of the gaps; c) curricular attitude and d) autonomy/agency development. Also, it was possible to observe the improvement of critical features in some participants and as they found it strange, they deconstruct and took different positions as from the discussions regarding the proposed themes.

Population aging is a global phenomenon related to changes in family structures and functions that bring consequences to the elderly, such as: change in living conditions, challenges in the care and social support, among others. This study aims to analyze the relationship between care system, social support and the fragility of senior caregivers in the context of high social vulnerability. It is an exploratory and analytical study, using the quantitative method of investigation. The population analyzed consisted of people aged 60 or over, who takes care of the seniors and were registered in the ”Unidades de Saúde da Família” (Public Family Health Units) in a city in the state of São Paulo and who are under the care of “ Núcleo de Apoio a Saúde da Família (NASF)” (Center for Support for Family Health), in the region of ARES “Cidade Aracy” (Aracy City). Interviews were conducted in the homes of elderly caregivers and used the following instruments for data collection: Semi-Structured Interviews, The Addenbrooke's Cognitive Examination Revised (ACE R), Geriatric Depression Scale (GDS), Fragility Assessment according to phenotype Fried, family APGAR, Genogram and ecomap. Most of the caregivers are spouses (83.6%), carefully time 1-4 years (46.5%) and spending one to four hours taking care (52%) of the elderly. The most mentioned institution that assists these seniors was a health institution. The main care provided to the elderly was feeding (82.2%), followed by lead to medical appointments (63.6%). There was a statistically significant association of low-income seniors with worse cognitive performance and the negative influence of the largest number of people living at home with worse results in cognition test. It is necessary to investigate the profile of these caregivers, as most are pre-fragile, and takes care of another pre-fragile elderly. It is noteworthy that the vast majority of the elderly in this study lives in houses with a large number of people, which is common in the context of high social vulnerability and low education; it was found that this factor interferes in the cognitive performance. More studies are necessary in order to investigate the conditions offered by the society and what these seniors, families and their social network can do in favor of a healthy aging.

This study consists in the synthesis and characterization of gas sensors based on hexagonal sodium-tungsten bronze powders (NaxWO3+x / 2.yH2O), whereas the gas sensors were synthesized by two routes. Both used as acid precipitation method in a sodium tungstate dihydrate solution (Na2WO4 • 2H2O). The routes were different by heating systems and in the first route obtained by the microwave-assisted hydrothermal method (HM). The second one was a hot plate with a magnetic stirrer (HP). Both syntheses were very efficient from the point of view of energy expenditure, because we obtained the NaxWO3+x/2.yH2O in short time and low temperatures. Samples were characterized by means of Raman spectroscopy, Fourier Transform Infrared (FTIR), absorption in the ultraviolet and visible region (UV-Vis), photoluminescence and energy dispersive X-rays (EDS), X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The bronze sensors obtained were tested against NO2 and the samples prepared by both routes were proved to be sensitive to gas. The HM samples had a higher sensitivity (Rgas / Rar ≅ 7 for 100 ppm of gás) and response time (of 1.5 minutes), with a working temperature of 250 ° C. On the other hand, the samples obtained by the PA method had the advantage of operating at working temperature of about 150 ° C, but with lower sensitivity and with a greater response time and recovery time (≅ 10 minutes). From the analysis of the photoluminescence measurement, it was possible to observe some possible relations between the type of defect as well as the sensitivity. It indicates that the larger the contribution of shallow defects in the samples, the greater sensitivity. It is suggested, therefore, from these data, that the sensor property in NaxWO3+x/2.yH2O system can be improved by the control of the defects.

We present a study of rank-one perturbations of self-adjoint and unitary operators, in particular related to the so-called Kotani’s trick. In Chapter 2 we recall relevant definitions and elementary facts. In Chapter 3 we present recent results by Marx, which involve self-adjoint operators and Hausdorff measures. A generalization of such results to the set of unitary operators is described in Chapter 4.

Published in 1979, the work Florbela Espanca: vida e obra, by Agustina Bessa-Luís, shows itself as a complex characterization text to fitness in a unique literary genre, due to compose, in a first aspect, a narration of life. However, it is clear that it is not just from a pure character and simply biographical, suggesting a fluid possibility between referentiality and fictional categories. For this, the presented concerns revolve around the question how Agustina’s work feed in a hybrid communion of different textual categories. Our interests are, also, observe how this kind of genre complexity is an occurrence in author conception, mainly in the Portuguese scene after the Revolução dos Cravos placing it thus in line with female authors, allowing a contemporary work analysis, in addition to their compliance with certain neobarroco procedures that approaches the textual structure to a kaleidoscope image and its effects in the whole composition.

The development and maintenance of vocal verbal repertories that follow structural regularities are processes in need for investigation under the selection by consequences paradigm. The present study investigates the effects of presenting vocal models in passive voice and explicit consequences, of high and medium preference, contingent to descriptions in active voice on the verbal voice of descriptions of Brazilian young children, 4 years old on average. Three experiments were performed. In the first, four children participated. The experimental procedure was composed by five conditions. In the first one, 10 drawings, with two animals interacting, were presented and its descriptions asked. In the second, experimenter and participant alternated in describing 20 drawings, the experimenter always described in passive voice. The third condition was similar to the second, except that descriptions in active voice (divergent) were followed by preferred consequences. The fourth condition was similar to the first one. The fifth condition was similar to the fourth, but it was conducted by an unknown experimenter. All participants described in passive voice after being exposed to the model and continued doing so even when preferred consequences followed descriptions in active voice. But the experimental design may have created a sequence effect between the second and the third conditions. Such limitation was followed in a second experiment. Other four young children participated, 4 years old on average. The procedure was similar to the first experiment, but, the model in passive voice during the second condition was replaced by the presentation of preferred explicit consequences contingent to active voice descriptions. All participants described in passive voice after being exposed to the model, except one. In order to refine the investigation, a third experiment was conducted. Other four young children mean of 4 years old, with different degrees of model following participated. The procedure was identical to the second experiment, but a pre-experimental condition was added in order to measure the participants’ sensibility to the model. Nevertheless, all participants described in passive voice after being exposed to the model in the third experimental condition. The findings point to the importance of investigations on non-arranged contingencies of reinforcement in the development and maintenance of verbal vocal repertoires that follow structural regularities.

This study, conducted from bibliographical research with primary sources, deals with the relationship between curriculum and history of Physical Education in Brazil, in First Brazilian Republic (1889-1930) and Vargas Era (1930-1945) periods. Initially, it presents an analysis of the Comenius' Didactica Magna, Society of Jesus' Ratio Studiorum and Brothers of Christian Schools' Conduite des écoles chrétiennes, as historical landmarks of modern curriculum. Then it brings the debate about the Traditional, Critical and Post-Critical theories of curriculum, in particular, the brazilian's Physical Education curriculum. Further, based on authors of the curriculum field of study and using an historical perspective, it delimits the concept of written curriculum. Using that concept, it identified written curriculum manifestations in the concrete reality of Brazilian education. As it approaches the relationships involved in the historical production of the curriculum, it defines two temporal cut. The first, from Arthur Higgins' Compendio de gymnastica e jogos escolares publish (1896) to 1929, date in which the so-called French method was introduced in civil Physical Education, becoming mandatory in all educational institutions in Brazil. The second, Regulamento (N° 7) da Educação Física (Método Francês) publish (1932) until the year 1945, characterized by weakening of French doctrine and military ideas, which mark the end of the Vargas Era. Finally, it concludes that Higgins' Compendio is a watershed in the history of Brazilian Physical Education curriculum, because it has the kind of modern curriculum development, based in Traditional Curriculum features in development in the first decades of the twentieth century. This study also affirms that the Regulamento (No. 7) was produced in complementary relationship to the Revista da Educação Física, a fact that reveals one of the ways in which the curriculum of the Brazilian Physical Education developed in that historical period.

In this work , we present an extension of the objective bayesian analysis made in Fonseca et al. (2008), based on Je reys priors for linear regression models with Student t errors, for which we consider the heteroscedasticity assumption. We show that the posterior distribution generated by the proposed Je reys prior, is proper. Through simulation study , we analyzed the frequentist properties of the bayesian estimators obtained. Then we tested the robustness of the model through disturbances in the response variable by comparing its performance with those obtained under another prior distributions proposed in the literature. Finally, a real data set is used to analyze the performance of the proposed model . We detected possible in uential points through the Kullback -Leibler divergence measure, and used the selection model criterias EAIC, EBIC, DIC and LPML in order to compare the models.

The main objective of this research is to characterize elements of personal and professional development and participation in the proposed training process that may have influenced the construction of teacher identity and mentor identity of professionals in training on Online Mentor Education Program. Specifically, it also seeks to answer the following research questions: which aspects possibly relates to the construction of mentors identity throughout his personal history, work and participation in the Online Training Program Mentors? Which specific, pedagogical and about the mentor function knowledge, components of teacher identity, are presented by mentors that will help them to play their new role? The program has, as its main objective, to train experienced teachers in mentors for follow up and support early career teachers in their anguish and features needs that characterize this stage. The theoretical framework on which it has based this research take into account teacher education and its characteristics; the stages of teaching profession and teachers professional development; teaching continuing education in their different contexts, such as courses, self-education and training within the school; teacher identity and its components; experienced teachers; processes of mentoring, mentors and their knowledge; considerations of distance education, online teacher education and virtual learning environments. The research was guided on a qualitative approach, with the data analysis supported by the descriptive-interpretative and biographical-narrative methodology. Data collection occurred in the selected participants production and activities carried out in the Online Mentor Education Program, featuring a documentary analysis. Data were organized in NVIVO, software that helps quantitative analisis with data organization. After this organization, data were classified manualy in the categories with NVIVO, inserted in frames and subsequently the creation of subcategories and the reclassification of the data, it results in frames that were analysed. The results indicate various aspects of personal and professional background of the participants, as his childhood and schooling, difficulties in their early careers, assistance from peers, continuing education courses, among others that possibly are related to the construction of their professional identity and hence may affect their identity as mentors. In addition, the mentors have a solid knowledge base, however, that does not identify an established mentor identity. In this way, it is possible to observe that it is under construction as it is dynamic. Mentors have a knowledge base that enables them to start mentor actions, in order to help beginning teachers and arrange his own development as a mentor.

The objective of this study was to evaluate the production of sugar cane syrups using enzymes of Saccharomyces cerevisiae from bakery yeast. The effect of theconcentration of yeast, reaction time and temperature for the hydrolysis of crystal sugar solution (VHP) in the physico-chemical properties and sucrose inversion rate were evaluated. Subsequently, the selected parameters were applied in order to hydrolyze sugarcane juice from three different seasons of the year. Finally, the optimized parameters were used to produce the syrups and their physico-chemical and sensory properties were compared to the syrup produced without sucrose hydrolysis. Physico-chemical analyzes showed percentage of total soluble solids (TSS), varying between 74.60 and 76.37%, reducing sugars (RS) between 12.00 and 27.54%, total reducing sugars (TRS) from 67.92 to 70.34%, pH between 4.95 and 4.97, sucrose inversion rate between 14.40 to 39.35%, water activity of 0.75 to 0.78 and instrumental color (L*, a*, b* parameters) from 21.50 to 24.61, 1.04 to 2.45, and 1.12 to 4.53, respectively. The attributes obtained from descriptive quantitative analysis (QDA) were color, brightness, sugarcane syrup and yeast aroma, sweet and acid taste, viscosity. The untreated syrup was the least preferred. Results indicate a viable and low cost solution for syrup production with a reducing sugar content of about 30%, ensuring a better stability in relation to sucrose crystallization, which is frequently associated as a negative aspect of product quality.

As a result of the military regime, Brazil was the stage for the different protagonists of civil society and its social movements, fighting for democratisation of the country and by the exercise of citizenship. People with disabilities were not alien to these processes and were important characters in this context of redemocratization of the country struggles for social rights, civil and political rights, in addition to the search for social visibility and autonomy in driving the own path of life. These movements also occurred in a scenario of institutions for rehabilitation of philanthropic and other associations while spaces of coexistence and solidarity and support to deal with issues relating to disability. When considering the social movements of people with disabilities and their organizations as important interlocutors of social control, for the construction of alternatives for assistance and struggle for rights, this study aimed to identify how they have acted in the conquest and exercise of human rights organizations, associations and groups of and for people with disabilities, present in São Carlos, SP. In addition, we sought to recognize what is the contribution of occupational therapists, inserted in these organizations in the conquest of the rights of persons with disabilities. Participated of the study a group of parents, two NGOs, three associations, a Pastoral and the Municipal Council of the disabled person. In the development of the research, semistructured interviews with the coordinators and presidents, in order to identify the organizations, the services and actions developed; the participant observation of some meetings, meetings and assemblies and documental research of the conferences in the sector of municipal education, health and social assistance and the Statute, folders and primers, produced by the organizations, as well as the laws and decrees prevailing in municipal and national scope. Also it was performed a punctual interview with occupational therapists, with the purpose of analyzing the role of the profession in this scenario of struggles and construction of assistance. The methods were supported by roadmaps and by the field diary. The records were guided by conceptions of the health area on the social control and the theoretical assumptions of Hannah Arendt on private and public space and the political action of individuals. The data were organized in two major categories of analysis: the trajectory of the movement to fight for the rights of people with disabilities in São Carlos, SP and the Council of the Rights of the person with disabilities in regional scenario, and the respective subcategories. It was found a potential of entities in the provision of services, by the provision of assistive technology and conquest of social rights. However, there is a fragile network of articulation between them and with other equipment and social institutions, for the development of collective actions and the exercise of social control. In addition, social and political participation of people with disabilities is also weakened or nonexistent. Many of them still remain in the private space of their homes and without access to essential rights.

Introduction: Pressure ulcers (PU) are common complications in patients with spinal cord injury (SCI). The peak pressure on the ischial region in individuals with SCI are higher than those found in subjects without physical disabilities and this fact is justified by sensitivity, motor and vasomotor changes. Objective: To compare the pressure distribution on the seat of the wheelchair of subjects with SCI using 3 different types of cushions (Roho®, Varilite® and Varilite®). Methodology: we selected 10 participants of both genders with SCI (n=05 tetraplegia and n=05 paraplegia). The analysis of the pressure on the seat was performed during two different situations: with the participant sitting in static posture and another step using the wheelchair for locomotion. Results: For the first step to Jay® showed the best rates for average pressure and also the contact area (p<0,001), the Roho® showed the best index for peak pressure (p<0,002). In the step with the wheelchair moving, Jay® showed the best average pressure (p<0,001), the Roho® had the lowest average for the peak pressure (p<0,002), and Varilite® provided the highest means for the contact area of the buttocks and thighs (p<0,006). All cushions evaluated showed lower values to those considered risk factors for PU, ratifying the importance of its use for the prevention. Conclusion: The use of cushions are effective measures to aid in the prevention of PU in people with SCI, but do not replace other ways of prevention. There is the need for proper cushion calibration and guidance on its use to get the desired effects.

In this work, carbon black Vulcan XC-72R was functionalized using five different treatments, the oxidizing agents employed were: nitric acid, sulfuric acid and hydrogen peroxide. The physical characterization of functionalized samples was carried out using scanning electron microscopy (SEM) and Raman spectroscopy. The results suggested that the treatments did not significantly alter the morphology of the material in most cases and showed an increase in the number of defects attributed to the introduction of oxygenated functional groups. Glassy carbon electrodes (GCE) were modified with aqueous dispersions of materials in dihexadecyl hydrogen phosphate (DHP). For the electrochemical characterization of the electrodes were performed studies of cyclic voltammetry employing the probe potassium hexacyanoferrate (III). For all cases there was an increase in the electroactive area as a result of the functionalization. Subsequently, the response of the electrodes to different analytes (dopamine, catechol, paracetamol and hydroquinone) was evaluated, the electrode modified in a mixture of nitric and sulfuric acid 1:1 (CB–HNO3/H2SO41:1–DHP/GCE) showed the highest analytical signal for the different compounds tested. Calibration curves were constructed for the determination of dopamine using the GCE electrode, the electrode prepared with unmodified CB (CB–DHP/GCE) and the CB–HNO3/H2SO41:1–DHP/GCE electrode, the sensitivities of the analytical curves (angular coefficients of the analytical curves) were: 0.334, 3.65 and 6.54 A cm−2 L mol−1, respectively. These results show a significant increase in sensitivity as a result of the functionalization xvii of CB suggesting an advantage over the use of unmodified material for electroanalytical applications. Then, an analytical procedure for the determination of sodium benzoate (sodium salt of benzoic acid) based on enzyme inhibition was developed, where the tyrosinase enzyme was immobilized at the surface of the CB– HNO3/H2SO41:1–DHP/GCE electrode (biosensor). Studies of the inhibition mechanism and optimization of operating conditions were performed. The corresponding analytical curves had linear concentration ranges between 4.90 × 10−7 and 1.92 × 10−5 mol L−1 and a detection limit of 2.1 × 10−7 mol L−1.
