New method to assess the pozzolanic reactivity of mineral admixtures by means of pH and electrical conductivity measurements in lime:pozzolan suspensions

A very simple method based on electrical conductivity and pH measurements was proposed for assessing reactivity of pozzolans. Calcium hydroxide: pozzolan water suspensions were monitored by means of measurements of electrical conductivity and pH values. In these suspensions, Ca(OH)(2) in solid state was initially present, being them, thus, saturated in this reagent. Three testing temperatures were selected (40, 50 and 60 degrees C). In the experiments carried out, calcium hydroxide was suspended in deionized water for yielding a lime saturated suspension. The addition of siliceous pozzolan (two types of rice husk ash RHA and two types of densified silica fume DSF were tested) to the saturated lime suspension can produce the unsaturation of the system, depending on the testing time, testing temperature and reactivity of pozzolan. When unsaturation was reached, the loss of electrical conductivity was higher than 30% and the variation of pH was higher than 0.15 units. These threshold values were selected for characterizing the reactivity of pozzolans by means of a proposed template, classifying the pozzolan in three different reactivity levels.

Artemídia preferente: fenômeno jogar & ler nas histórias em quadrinhos interativas (HQI) com os games de RPG

This artistic-scientific process aims to innovate the concept of Interactive Comics by adding them into the concept of RPG games and Single-Adventures. To make it properly done, there will be some issues about Interactivity, history of the Comic Strip and Mangas, and their techniques of use. Also, there will be other issues involving Electronic Comics and Interactive Comics, in addition to the concept of the RPG games and Single-Adventures, so that the reader of this paper could understand the practical result of every issue combined into one. The identification of these issues is made from a bibliographic and iconographic research, and it will also be displayed throughout the content. Some decisions will be thrown along this paper for the reader to decide and, therefore, understand the Interactivity process in a better way. The combined issues’ result will be presented in my interactive website, http://a3studios.com.br/iss/home (address not final) or http://amstarproductions.net (final address), where the readers will have to experience the “Play&Read” phenomenon. Furthermore, this work is inserted in the line of the research Artistic Processes and Procedures of the Department of Fine Arts from the Art Institute of UNESP, whose methodology used was the Freinet Educational Cybernetics, developed in the research group Media Arts and Videoclip leaded by the leading advisor for this Final Course Work.

HQtrônica: atividade programada e curso de extensão

This Final Course Work’s main subject comes from a study made on my previous Final Course Work titled “Artemídia Preferente: Fenômeno ‘Jogar&Ler’ nas Histórias em Quadrinhos Interativas (HQI) com os games do RPG”, and it is fed by the shortage of Electronical Comic publications, classes, courses and activities that could suit for educational purposes and experiences for a capable kind of audience to learn it and do it. Specific issues about Electronic Comic will be presented, based on Célestin Freinet’s Pedagogy, on some books about Methodology and on the Brazilian Curriculum Guidelines required for graduation. After that, a Lesson Plan will be developed for a 14 year-old-or-older kind of audience where they will be capable of making their own Electronic Comic, being it educational-themed or not. This study also cares about the participants’ influences on their lives to be completed. Furthermore, this work is inserted in the line of the research “Artistic Processes and Procedures” of the Department of Fine Arts from the Art Institute of UNESP, whose methodology used was the Freinet Educational Cybernetics, developed in the research group “Media Arts and Videoclip” leaded by the leading advisor for this Final Course Work.

A new biomimetic sensor based on molecularly imprinted polymers for highly sensitive and selective determination of hexazinone herbicide

A new selective sensor based on molecularly imprinted polymers (MIPs) was developed for the determination of hexazinone (HXZ) in environmental samples. MIPs were synthesized using a non-covalent approach, and selection of the monomers employed in the polymerization reaction was carried out by molecular modeling. Three functional monomers with high (2-vinylpyridine (MP17)) and intermediate (methacrylic acid (MP12) and acrylamide (MP5)) energies of binding to the template (HXZ) were selected for preparation of the MIPs, in order to conduct comparative studies and validate the theoretical data. For sensor construction, carbon pastes were modified with each MIP or NIP (non-imprinted polymer), and HXZ determination was performed using differential pulse adsorptive cathodic stripping voltammetry (DPAdCSV). All parameters affecting the sensor response were optimized. In HCl at pH 2.5, the sensor prepared with MP17 (5% w/w in the paste) showed a dynamic linear range between 1.9 × 10−11 and 1.1 × 10−10 mol L−1, and a detection limit of 2.6 × 10−12 mol L−1, under the following conditions: accumulation time of 200 s at a potential of −0.5V, scan rate of 50 mVs−1, pulse amplitude of 60 mV, and pulse width of 50 ms. The sensor was selective in the presence of other similar compounds, and was successfully applied to the analysis of HXZ in river water samples.

Casos de ensino relacionados à educação física escolar: uma produção dos alunos do ensino médio

Teaching cases are records, through written narratives, of an academic episode or incident, they appear in educational scenery as a rich strategy not only for the teacher's conformation but also for their investigation. The bibliography shows that young students are still not very much investigated and it contributes to the establishment of negative images of this social subject. In this sense, the objective of this work is to analyze the stories and episodes, called teaching cases, in narrative style, written by students from High School about their physical education classes. The participants of this study are High School students from two public schools from two cities in the countryside of São Paulo state. The researcher stayed in the schools for nine months and in this meantime she made contact with the students, asking, for the ones who showed interest, the construction of teaching cases. For this interested students, the researcher explained researcher explained what teaching cases are, as well as, she presented a template to guide them in the production. At the end of this process, twenty teaching cases were delivered to the researcher. They were analyzed under the qualitative approach, valuing the expressive wealth in the narratives, complemented by the interviews with the authors. Inset the mosaic of narratives and interviews, showing a variety of experiences and possibilities of distance and approximation of the students to the physical education classes, we can indicate that from the 20 cases, only one was set as a total distance from the physical education classes (this is the student's situation since she was in the second grade from elementary school). Mentioning the positive experiences and the approximation to the physical education classes, the association of teaching cases and interviews showed that seven students lived the context and until today present an affective proximity to the classes. These evidences can help...

Digital radiography for determination of primary tooth length: in vivo and ex vivo studies

Background. Methods for determining the root canal length of the primary tooth should yield accurate and reproducible results. In vitro studies show some limitations, which do not allow their findings to be directly transferred to a clinical situation. Aim. To compare the accuracy of radiographic tooth length obtained from in vivo digital radiograph with that obtained from ex vivo digital radiograph. Method. Direct digital radiographs of 20 upper primary incisors were performed in teeth (2/3 radicular resorption) that were radiographed by an intraoral sensor, according to the long-cone technique. Teeth were extracted, measured, and mounted in a resin block, and then radiographic template was used to standardise the sensor-target distance (30 cm). The apparent tooth length (APTL) was obtained from the computer screen by means of an electronic ruler accompanying the digital radiography software (CDR 2.0), whereas the actual tooth length (ACTL) was obtained by means of a digital calliper following extraction. Data were compared to the ACTL by variance analysis and Pearson’s correlation test. Results. The values for APTL obtained from in vivo radiography were slightly underestimated, whereas those values obtained from ex vivo were slightly overestimated. No significance was observed between APTL and ACTL. Conclusion. The length of primary teeth estimated by in vivo and ex vivo comparisons using digital radiography was found to be similar to the actual tooth length.

Measurement of differential cross sections for the production of a pair of isolated photons in pp collisions at root s=7TeV

A measurement of differential cross sections for the production of a pair of isolated photons in proton-proton collisions at root s = 7 TeV is presented. The data sample corresponds to an integrated luminosity of 5.0 fb(-1) collected with the CMS detector. A data-driven isolation template method is used to extract the prompt diphoton yield. The measured cross section for two isolated photons, with transverse energy above 40 and 25 GeV respectively, in the pseudorapidity range vertical bar eta vertical bar < 2.5, vertical bar eta vertical bar (sic) [1.44, 1.57] and with an angular separation Delta R > 0.45, is 17.2 +/-0.2 (stat) +/-1.9 (syst) +/- 0.4 (lumi) pb. Differential cross sections are measured as a function of the diphoton invariant mass, the diphoton transverse momentum, the azimuthal angle difference between the two photons, and the cosine of the polar angle in the Collins-Soper reference frame of the diphoton system. The results are compared to theoretical predictions at leading, next-to-leading, and next-to-next-to-leading order in quantum chromodynamics.
