Published: March 2017

Fourier Transform Infrared Spectroscopy (FTIR) and X-Ray Diffraction (XRD) test were utilized to detect the phase transformation of a HA/Ti Functionally Graded Material (FGM) prepared via Powder Metallurgy (PM) technique. The effects of oxygen (O2), nitrogen (N2), forming (N2+H2) and Argon (Ar) sintering atmospheres on the FGM specimens were examined by considering the gas flowing duration. It was found that the original metallurgical profile of pure Ti in HA/Ti FGM sintered under N2 atmosphere was almost preserved. However the carburization of the pure Ti was observed on the specimen. Medium alkyl halides (C-Br) and alkenes (-C=C-) stretches were detected, producing the dominant elements in the pure Ti layer of the specimen. The almost stable constituent element remains in the specimen sintered under flowing N2+H2 atmosphere as detected by XRD result. This proved the significance of controlling the sintering atmosphere during the entire sintering process. The results achieved reveal the high tendency of Ti and HA elements to react with the sintering environment, thus very precise furnace with controllable atmosphere is crucial for the fabrication of the HA/Ti FGM.
Addressing Flux Dip Challenges for 3-D Integrated Large Die, Ultrafine Pitch Interconnect
Authors: Marsan-Loyer C. , Danovitch D. , Boyer N.
Published: March 2017

The requirement for closely coupled, highly integrated circuits in the semiconductor industry has spawned alternative packaging innovations such as 2.5-D/3-D integration. The incredible potential of this alternative comes with great challenges, not the least of which is the unprecedented reduction in package interconnection pitch. Market acceptance of new fine-pitch microelectronic products is strongly dependent on the development of flawless assembly processes that align with the traditional Moore-like expectation of higher performance without cost penalty. One such process is the application of flux to the interconnect surfaces to achieve effective joining. Insufficient flux quantity or flux activity can impede the formation of solid, reliable joints, whereas excessive quantities or activity can cause solder bridging or difficulties with downstream operations such as residue cleaning or underfill reinforcement. This delicate balance, already complex for traditional chip joining, is further challenged by the geometrical and spatial reductions imposed by pitch miniaturization, especially where large die, with over 100,000 interconnects, are concerned. This article presents an overall development protocol to evolving a flux dipping operation to production-level thermocompression assembly of large die (8 × 11 × 0.780 mm) with 11,343 ultrafine pitch (62 μm) copper pillar interconnections. After reviewing the state of the art for fluxing technology and detailing the specific technical issues, we present and defend the chosen flux application approach with its corresponding parameters of interest. Physical and chemical characterization results for selected flux material candidates are reported in conjunction with an analysis of how their properties correlate to the flux dip application parameters. As part of this fundamental understanding, we investigate and report on flux dip coating behavior and how it compares to other industrial dip coating applications. Finally, the results of process assembly experiments in a production-type environment are reviewed and discussed with respect to the previous characterizations. These experiments span downstream assembly process compatibility (i.e., cleaning and underfill) as well as product reliability.
Optical Beam Propagation and Ray Tracing Simulation of Interruption-Free Asymmetric Multimode Bus Couplers
Authors: Lorenz Lukas , Nieweglowski Krzysztof , Wolter Klaus-Jürgen , Loosen Florian , Lindlein Norbert , Bock Karlheinz
Published: March 2017

In this article, we present a coupling concept for an interruption-free asymmetric bidirectional optical bus coupler for board and module level. With this approach, it is possible to connect several electro-optical devices to a single waveguide. A core-to-core connection principle is used, where the cores get into physical contact at their side faces. The coupling ratio can be tuned by adjusting the overlap area of the two cores with different contact pressures. Because of a bending in one of the waveguides, it is possible to achieve a specific asymmetric coupler design, where the coupling ratio depends on the coupling direction (bent waveguide to rigid one or vice versa). To derive design rules for prototyping, a simulation is performed using two different independent approaches for cross-checking. With a ray tracing simulation, coupling ratios and energy distribution within the bent core are analyzed. In addition, a simulation with the beam propagation method is used to take wave optical effects into account as well as to establish a holistic view on the coupling concept.

Bilateral Proprioceptive Evaluation in Individuals With Unilateral Chronic Ankle Instability
Authors: Sousa Andreia S. P. , Leite João , Costa Bianca , Santos Rubim
Published: March 2017

Context: 

Despite extensive research on chronic ankle instability, the findings regarding proprioception have been conflicting and focused only on the injured limb. Also, the different components of proprioception have been evaluated in isolation.

Objective: 

To evaluate bilateral ankle proprioception in individuals with unilateral ankle instability.

Design: 

Cohort study.

Setting: 

Research laboratory center in a university.

Patients or Other Participants: 

Twenty-four individuals with a history of unilateral ankle sprain and chronic ankle instability (mechanical ankle instability group, n = 10; functional ankle instability [FAI] group, n = 14) and 20 controls.

Main Outcome Measure(s): 

Ankle active and passive joint position sense, kinesthesia, and force sense.

Results: 

We observed a significant interaction between the effects of limb and group for kinesthesia (F = 3.27, P = .049). Increased error values were observed in the injured limb of the FAI group compared with the control group (P = .031, Cohen d = 0.47). Differences were also evident for force sense (F = 9.31, P < .001): the FAI group demonstrated increased error versus the control group (injured limb: P < .001, Cohen d = 1.28; uninjured limb: P = .009, Cohen d = 0.89) and the mechanical ankle instability group (uninjured limb: P = .023, Cohen d = 0.76).

Conclusions: 

Individuals with unilateral FAI had increased error ipsilaterally (injured limb) for inversion movement detection (kinesthesia) and evertor force sense and increased error contralaterally (uninjured limb) for evertor force sense.
Promising and Established Investigators' Experiences Participating in the National Athletic Trainers' Association Foundation Research Mentor Programa
Authors: Nottingham Sara L. , Mazerolle Stephanie M. , Barrett Jessica L.
Published: March 2017

Context: 

Mentorship is a helpful resource for individuals who transition from doctoral student to tenure-track faculty member. The National Athletic Trainers' Association (NATA) Research & Education Foundation offers a Research Mentor Program to provide mentorship to promising investigators, particularly as they work to establish independent lines of research.

Objective: 

To gain the perspectives of promising and established investigators on their participation in the NATA Foundation Research Mentor Program.

Design: 

Qualitative, phenomenological research.

Setting: 

Higher education institutions.

Patients or Other Participants: 

Seven promising investigators (5 women, 2 men) and 7 established investigators (2 women, 5 men), all of whom had completed the NATA Foundation Research Mentor Program.

Data Collection and Analysis

We developed and piloted intervi: ew guides designed to gain participants' perspectives on their experiences participating in the NATA Foundation Research Mentor Program. Semistructured telephone interviews were completed with each individual and transcribed verbatim. Data were analyzed using a phenomenological approach, and saturation was obtained. Trustworthiness was established with the use of member checking, multiple-analyst triangulation, and data-source triangulation.

Results: 

Three themes emerged from the interviews: (1) motivation, (2) collaboration, and (3) resources. Participants were motivated to become involved because they saw the value of mentorship, and mentees desired guidance in their research. Participants believed that collaboration on a project contributed to a positive relationship, and they also desired additional program and professional resources to support novice faculty.

Conclusions: 

Promising and established investigators should be encouraged to engage in mentoring relationships to facilitate mentees' research agendas and professional development. The NATA Foundation and athletic training profession may consider providing additional resources for novice faculty, such as training on effective mentoring; grant writing and other research-related tasks; and support for broader faculty responsibilities, such as teaching, service, and work-life balance.

Published: March 2017

Bacground: The combination of paclitaxel and cetuximab (PaCe) has led to an encouraging response rate in Phase 2 setting with limited toxicity. The aim of our study was to assess the efficacy of this regimen in our setting in platinum sensitive and nonsensitive patients. Methods: This was a retrospective analysis of head and neck cancer patients treated with weekly PaCe as palliative chemotherapy between May 2010 and August 2014. The standard schedule of cetuximab along with 80 mg/m2 of weekly paclitaxel was administered till either disease progression or withdrawal of patient's consent. The toxicity and response were noted in accordance with CTCAE version 4.02 and RECIST version 1.1 criteria, respectively. The response rates between platinum sensitive and nonsensitive patients were compared by Chi-square test. Overall survival (OS) and progression-free survival (PFS) were estimated by Kaplan–Meier survival method and log-rank test was used for comparison. Cox proportional hazard model was used for identification of factors affecting PFS and OS. Results: One Hundred patients with a median age of 52 years (interquartile range: 46–56 years) were included. Forty-five patients (45%) were platinum insensitive, whereas 55 patients (55%) were platinum sensitive. In platinum insensitive patients and sensitive patients, the response rates were 38.5% and 22.2%, respectively (P = 0.104), whereas the symptomatic benefit in pain was seen in 89.5% and 71.7%, respectively (P = 0.044). The median PFS in platinum insensitive and sensitive patients were 150 and 152 days, respectively (P = 0.932), whereas the median OS was 256 days (95% confidence interval [95% CI]: 168.2–343.8 days) and 314 days (95% CI: 227.6–400.4 days), respectively (P = 0.23). Nineteen patients (19%) had grades 3–4 adverse events during chemotherapy. Conclusion: Weekly paclitaxel combined with cetuximab has promising efficacy and good tolerability in the palliative setting in advanced head and neck cancer in both platinum sensitive and insensitive patients.

Published: March 2017

Bacground: First-line maintenance with erlotinib in nonsmall cell lung cancer (NSCLC) patients without progression after four cycles of chemotherapy was well tolerated and significantly prolonged progression-free survival (PFS) compared with placebo. Aim and Design: This open-label, single arm, Phase IV, interventional study was designed to evaluate erlotinib as first-line maintenance after chemotherapy in Indian NSCLC patients. Primary efficacy objective was to evaluate PFS rate (PFSR) at week 52 and secondary objectives were determination of PFS, overall survival (OS), overall response rate (ORR), disease control rate, and safety. Subjects and Methods: Patients were treated with erlotinib until disease progression/death/unacceptable toxicity or end of study. Patients with disease progression underwent scheduled clinical assessments every 12 weeks thereafter. Kaplan–Meier estimates were used to evaluate PFSR, PFS, and OS. The ORR was summarized using number and percentage along with two-sided 95% Clopper–Pearson confidence interval. The incidence of adverse events (AEs) and serious AEs (SAEs) was tabulated according to severity, outcome, and relationship to erlotinib. Results: Of the 51 enrolled patients, 47 patients completed the study (2: Continuing treatment, 41: Disease progression, and 4: Death) and four patients discontinued treatment (3: Lost to follow-up; 1: Withdrew consent). PFSR was 22.5% at 12 months, median PFS 99 days (14.14 weeks), and median OS was 671 days (22 months). The probability of OS was 74.5% at 14 months. The ORR was 25.5%, and disease control rate was 55.3%. AEs were reported in 62.7% and SAE in 7.8% of patients. Common AEs were diarrhea and rash. Conclusions: Erlotinib was well tolerated by Indian patients in first-line maintenance setting and resulted in median PFS of 14 weeks and median OS of 22 months better than previously reported and with no new safety concerns in this population.

Interchangeable Positions in Interaction Sequences in Science Classrooms
Authors: Rees Carol , Roth Wolff-Michael
Published: March 2017

Triadic dialogue, the Initiation, Response, Evaluation sequence typical of teacher /student interactions in classrooms, has long been identified as a barrier to students’ access to learning, including science learning. A large body of research on the subject has over the years led to projects and policies aimed at increasing opportunities for students to learn through interactive dialogue in classrooms. However, the triadic dialogue pattern continues to dominate, even when teachers intend changing this. Prior quantitative research on the subject has focused on identifying independent variables such as style of teacher questioning that have an impact, while qualitative researchers have worked to interpret the use of dialogue within the whole context of work in the classroom. A recent paper offers an alternative way to view the triadic dialogue pattern and its origin; the triadic dialogue pattern is an irreducible social phenomenon that arises in a particular situation regardless of the identity of the players who inhabit the roles in the turn-taking sequence (Roth & Gardner, 2012). According to this perspective, alternative patterns of dialogue would exist which are alternative irreducible social phenomena that arise in association with different situations. The aim of this paper is to examine as precisely as possible, the characteristics of dialogue patterns in a seventh-eighth grade classroom during science inquiry, and the precise situations from which these dialogue patterns emerge, regardless of the staffing (teacher or students) in the turn-taking sequence. Three different patterns were identified each predominating in a particular situation. This fine-grained analysis could offer valuable insights into ways to support teachers working to alter the kinds of dialogue patterns that arise in their classrooms.

Chavism and Criminal Policy in Venezuela, 1999-2014
Authors: Grajales Martha Lia , Hernández Maria Lucrecia
Published: March 2017

For a long time, the Venezuelan democracy was an exception in South America due to a party system that was based on what was known as the ‘Punto Fijo Pact’. At the start of the 1980s a series of economic, social and political events began to occur, which caused this ‘exceptionalism’ to stagger and disrupt the institutionality of the traditional Venezuelan democratic State. The events led to a deep national crisis and the birth of a new political era. By the end of the 1990s, there had been a significant shift towards left-wing governance. Hugo Chávez Frías subsequently won the presidential elections in 1998. This paper analyzes some aspects of the criminal policies that were implemented during the reign of left-wing leader Chávez till his death in 2013 and thereafter by Chavist party president elect, Nicolás Maduro during 2013-2014. Four stages can be identified in the behavior of incarceration rates. The first stage, from 1999 to 2000, was characterized by the lowest recordings of incarceration rates and the lowest measured percentage of preventive detention in Venezuela in thirty years. The second stage, from 2001 to 2005, saw a slight increase in the incarceration rate which then remained stable. The third stage, from 2006 to 2012, and the fourth stage, from 2013 to 2014, are characterized by sustained increases in preventive detention, incarceration and murder rates.
The 'Iron Fist’ of the Citizens’ Revolution: The Punitive Turn of Ecuadorian Left-wing Politics
Authors: Paladines Jorge Vicente
Published: March 2017

The punitive turn in Ecuadorian left-wing politics embodies a fundamental contradiction. On the one hand it involved extending social rights and resisting neoliberalism. On the other hand, punitive criminal justice policies intensified. This paper explores what, how, when and why this occurred to explain the complexity of Ecuador’s punitive turn under a period of twenty-first century socialism. Two eras of national policy will be compared. The first is known as the ‘long neoliberal night’ (the before); while the second is known as the ‘Citizens' Revolution’ (the present). The Citizens’ Revolution replaced neoliberal policies with social development, infrastructure, services and programs alongside the more equitable distribution of wealth. In a first moment, it also deployed strategies and actions towards penal moderation. However, since 2010, it has changed dramatically, generating an astonishing punitive turn. The article concludes that law and order policies in Ecuador therefore do not fit Loïc Wacquant’s (2013: 22) description of the ‘neoliberal penal paradox’.
Stability Analysis and Optimization of Airport Security System

Published: March 2017

In this paper, we have established a composite queuing network model on the basis of the queuing theory and combining with the current security system of the airport. We have made division of the whole security system into different processes which include ID check process, x-ray scanning process, and millimeter scanning process, and find out the unit of security system according to the proportion of different security lanes, what’s more, these processes were distinguished into different kinds of queuing system, and then, we established the queuing network using these different queuing model into the unit. We applied the method of computer simulation to analyze the bottleneck, and we find that ID check process in pre-check system is unstable based on the current proportion of pre-check lane. Meanwhile, we optimized the number of each unit using the system design model and prove the effectiveness by computer simulation, then, we optimized the service rate of the baggage and body screening in pre-check lane follow the above process. Finally, we further discussed development direction of this model.
The Exponentiated Generalized Standardized Half-logistic Distribution
Authors: Cordeiro Gauss M. , De Andrade Thiago A. N. , Bourguignon Marcelo , Gomes-Silva Frank
Published: March 2017

We study a new two-parameter lifetime model called the exponentiated generalized standardized half-logistic distribution, which extends the half-logistic pioneered by Balakrishnan in the eighties. We provide explicit expressions for the moments, generating and quantile functions, mean deviations, Bonferroni and Lorenz curves, and order statistics. The model parameters are estimated by the maximum likelihood method. A simulation study reveals that the estimators have desirable properties such as small biases and variances even in moderate sample sizes. We prove empirically that the new distribution provides a better fit to a real data set than other competitive models.

Published: March 2017

The objective of this study was to evaluate the effect of roasting on the nutritional and cosmetic potential of oil extracted from kernels of C. lanatus, which is one of the most widespread Cucurbitaceae species in Sub-Saharan Africa. The dried kernels (DKO) and roasted kernels (RKO) oils were extracted by cold press and hot using hexane. The physicochemical properties of these oils were evaluated. The results showed that C. lanatus roasted kernels were important sources of lipids (40.12 %) and protein (37.50 %). Oil extracted by press was of high quality, compared to that extracted by hexane. The study of the roasting effect revealed that the physicochemical characteristics of DKO and RKO oils were significantly different, with the exception of their specific gravity (≈ 0.9) and their refractive index (≈ 1.47). The absorbance of the two oils decreased in the range of UV-A and UV-B wavelengths. Both oils had low oxalates content (≈ 0.05 %) and were free of phytates and cyanogenic glycosides. All these features suggest that the roasted kernels oil of the C. lanatus could be used in food and cosmetic industries.
Towards a Professionalism of Agricultural Extension: Key to Promoting Extension Effectiveness in Africa
Authors: Agunga Robert , Sleshi Ruth , Hassen Rahwa
Published: March 2017

A survey of a small sample of 123 extension workers in Ghana and Ethiopia may have revealed the key issue facing extension ineffectiveness in Africa—the paucity of extension training. Questions on job satisfaction showed that respondents were highly satisfied with: a) an opportunity to work in an area they are trained (N=88, 57%), b) level of education (N=75 (61%), c) enthusiasm towards their work (N=72 (58.5%), and d) opportunity to work with local farmers. However, they were highly dissatisfied with: a) their salaries (N=108 (87.8%), b) the process of decentralization (N=83 (75.6%), c) cooperation from non-governmental agencies (N=87 (70.7%), d) respect from peers in other sectors of government (N=83 (68.0%), e) training in development (N=79 (65.3%), and f) training in communication (N=65 (54.2%). We find their complaints on lack of or limited training in development and communication worthy to note because in the last 40 years extension performance has stressed facilitation among development partners. It can be argued, therefore, that the slow process of decentralization, the friction between extension workers and their NGO counterparts, and their inability to get along with their compatriots in other ministries can be traced to their limited or lack of training in development and communication, otherwise called “Communication for Development” (C4D). We conclude, therefore, that if extension workers are to be effective in their new role as development facilitators not only must their training in agriculture expand to include C4D but, equally significant, extension systems throughout the continent must operate as a profession. Therefore, the authors recommend the establishment of a professional association throughout Africa, under the rubric of “ExtensionAfrica,” which will address the need for extension effectiveness on the continent. We particularly recommend a collaborative relationship with the African Forum for Agricultural Services (AFAAS), which has a mandate for advising on extension services, to make this happen.

O sistema de conjunção em textos acadêmicos: os mecanismos de sequenciamento e de explicação
Authors: Vian Jr. Orlando , Mendes Wellington Vieira
Published: March 2017

Dentre os seis sistemas discursivos propostos por Martin e Rose (2007 [2003]), o sistema de conjunção possibilita analisar as relações entre os processos de um texto com base em quatro tipos gerais de conjunções: adição, comparação, tempo e consequência. A partir de um recorte do corpusdos textos que compõem o SAL – Systemics Across Languages,nosso objetivo neste texto é observar como se caracterizam as relações conjuntivas em textos acadêmicos, com foco nas ocorrências léxico-gramaticais de sequenciamento e de explicação, como forma de explorar o texto acadêmico em quatro realizações distintas: um artigo de graduação, um trabalho de conclusão de curso de graduação, uma dissertação de mestrado e uma tese de doutorado. O objetivo primordial é explorar como os mecanismos estão organizados nos quatro níveis acadêmicos e o que revelam sobre a produção textual, fornecendo subsídios para outros estudos sobre textos e gêneros acadêmicos que, por sua vez, podem embasar propostas de letramento acadêmico, principalmente no que diz respeito à formação do pesquisador e sua produção textual e o ensino da produção escrita.

Published: March 2017

Studies of the urban climate involve numerous climatic variables, such as temperature, air humidity and vegetation. The objective of this research was to determine the trend of two meteorological variables (air temperature relative humidity), in relation to the arborization, sensation and thermal hygrometric perception of the population in the microclimate of two areas (A1 = Avenue Antônio Maia; A2 = Street 5 de Abril) Core Marabá Pioneira. For the measurement of temperature and humidity of the air, the methodology recommended by the Agronomic Institute of Campinas (IAC), adapted for the schedules and collection numbers, was applied. To obtain data on thermal comfort, seventy mixed forms were applied for two consecutive days at 12 hours. The thermal sensation was classified per the contained in the Predicted Mean Vote (PMV) and the discomfort, with the Thom Discomfort Index (ID). Twelve daily readings (6:00 a.m. to 5:00 p.m.) were carried out at each hour in the four meteorological shelters (two in each area) during 23 days of July 2015. The results indicated that the air temperature has tendencies to elevation, The relative humidity of the air, presents opposite tendency. The thermal sensation is very hot (+3), the satisfaction with shading was classified as good (A2 = 50%) and regular (A1 = 41.67%), thermal comfort (A1 = 28.76 °C; A2 = 27.70 ºC), ranges from uncomfortable to very uncomfortable. Therefore, there is a need to improve afforestation in the Marabá Pioneira Nucleus, in order to reduce the discomfort index and the quality of life of the population.

Pretende-se, neste artigo, apresentar uma análise do funcionamento da negação em Sateré-Mawé e sua relação com processos enunciativos que têm por objetivo focalizar diferentes termos do enunciado. Esta análise se fundamenta, principalmente, em pressupostos teóricos do Funcionalismo-Tipológico desenvolvidos por teóricos franceses. O corpus empregado para esta análise é constituído de enunciados retirados de textos escritos por professores indígenas e publicados sob a forma de livros de leitura para uso escolar; e de textos orais coletados por nós em situações reais de comunicação.
ENTRE A SEDUÇÃO E O SONHO: UMA LEITURA DE “O HOMEM DOS SONHOS”, DE MÁRIO DE SÁ-CARNEIRO, À LUZ DA FILOSOFIA DE SOREN KIERKEGAARD
Authors: Feitosa Márcia Manir Miguel , Sousa Leonardo Silva
Published: March 2017

O objetivo deste trabalho consiste em aproximar a Filosofia de Sören Kierkegaard (1813-1855) da Literatura de Mário de Sá-Carneiro (1890-1916), por meio da análise da personagem “O russo”, do conto O homem dos sonhos. À luz da estadia estética em Kierkegaard, inspirada na obra Diário de um sedutor, será possível identificar aproximações e afinidades entre as personagens e como se desenvolve esse estádio existencial no pensamento do filósofo dinamarquês.
NA RELAÇÃO LÍNGUA/POESIA: AS VERSÕES DOS BRASIS E SUJEITOS NACIONAIS
Authors: Almeida Eliana De
Published: March 2017

Este artigo propõe uma reflexão sobre a relação língua/poesia, conforme tomada nos estudos da linguagem, com base nos pressupostos teóricos da Análise do Discurso (PÊCHEUX, 1988; 2004; ORLANDI, 1999; MARIANI, 2004). Nosso interesse é mostrar como a separação entre língua/poesia, nesses estudos, produziu consequências teórico-analíticas em relação à leitura/interpretação do texto poético, donde advêm, ainda hoje, práticas tradicionais que desautorizam sua leitura pelas teorias linguísticas. Para além da teoria discursiva, a análise, que recorta a poesia Cabeludinho, da obra Poemas concebidos sem pecado (1937), de Manoel de Barros (1916-2014), mostra os modos pelos quais a linguagem (se) dobra sobre si mesma, ressaltando o funcionamento próprio da língua na contemporaneidade.
PO-ÉTICAS. O CULTIVO DA LÍNGUA COMO IDENTIDADE EM 5 PROPOSIÇÕES
Authors: Monteiro Hugo
Published: March 2017

Este texto parte de um único verso de A Mensagem, de Fernando Pessoa, para questionar o conceito de identidade e de cultura a partir da experiência poética. Convocando a interseção entre filosofia e poesia, faz-se alusão ao “more geometrico” de Espinosa, mas recorrendo preferencialmente a Deleuze, a Blanchot ou a Eduardo Lourenço como autores que suscetibilizam tanto um cruzamento entre filosofia e literatura quanto uma outra noção de identidade e de cultura.
A DISCURSIVIDADE DO CLIQUE NA PRODUÇÃO DE SENTIDOS E SUJEITOS
Authors: Chiaretti Paula
Published: March 2017

Apoiado na perspectiva teórico-metodológica da Análise de Discurso de filiação a Pêcheux, este trabalho busca analisar uma propaganda de um banco (“Corte os cliques da sua empresa”), que se apoia no uso de recursos tecnológicos para propor diferentes “soluções”. Buscou-se compreender de que modo a discursividade do “clique” funciona produzindo sentidos de imediato, literalidade, exatidão, precisão, correspondência, enfim, efeitos de sentido que apelam à completude (de sujeito e de sentido). Ao mesmo tempo, tentou-se mostrar os deslocamentos de sentido de liberdade e flexibilidade para os de codificação e prescrição.

N 1. P. 56-63. A FTIR spectroscopic study of aqueous solutions of sodium tungstate and molybdate (solution concentration was 0.1 mol/l) over a wide pH range (factor (level) of acidity Z, Z = C (H+)/C (WO42-) or Z = C (H+)/C(MoO42-)) was carried out. In solutions of sodium tungstate complex frequency band at 885-865 cm-1 correspoding to the stretching vibrations ν(W-O-W) was fixed. The frequency bands of 1720-1700 cm-1, 990, 985 and 1025 cm-1 corresponding to bending vibrations δ(W-OH) were fixed that indicates a significant change in composition of the solution as a result of hydrolytic and polycondensation processes. The sodium molybdate solution has not bands corresponding to the stretching vibrations v(Mo-O-Mo). Only the characteristic bands of the deformation vibrations δ(Mo-OH) were recorded. The low intensity complex band in the area of 885-865 cm-1 corresponding to the stretching vibrations ν(W-O-W) even for freshly prepared 0.1 mol/l sodium tungstate solution was appeared as well as the band at 1720-1700 cm-1 attributed to deformation vibrations δ(W-OH) that indicates a fast change in the solution composition. For solutions of sodium molybdate bands of stretching vibrations v(Mo-O-Mo) are fixed at a pH less than 6 after standing for several days. With Hydra/Medusa program diagrams of distribution of molybdate and tungsten particle depending on the pH were calculated. In relatively dilute solutions, the diagrams received with Hydra/Medusa program showed the only protonated (monomeric) form of molybdate ions, where as in the sodium tungstate solution until pH of 9 W6O216- and HW6O215- particles exist that agrees with the results of IR spectroscopy. The results of IR spectroscopy and modeling with Hydra/Medusa program will be used to support the pH operating range for molybdate and tungstate-selective electrodes, since they are an important feature of any analytical ion-selective electrodes. For tungstate-selective electrode it is necessary to maintain the pH less than 9, for molybdate-selective electrode - less than 8 (with dilute ammonia). Considering the changes in the composition of sodium molybdate and tungstate solutions, for the design of molybdate and tungstate-selective electrodes the freshly prepared solutions have to be only used, rather than stored for more than two days.

Study of electrochemical intercalation of graphite in solutions of HNO3 with method of chronovoltamperometry. Izv. Vyssh. Uchebn. Zaved. Khim. Khim. Tekhnol. 2017. V. 60. N 1. P. 34-39.The physico-chemical properties of suspensions of graphite-nitric acid were studied. The ratios of the components in suspension providing the possibility of their anodic oxidation with the formation of compounds of the implementation of graphite were determined. The values of electrical conductivity of suspensions of graphite-nitric acid with different ratio of the solid and liquid phases were determined .The maximum value of the electrical conductivity of suspensions is achieved at the mass ratio of graphite to HNO3» 1:0.66. The design of the electrochemical cell for carrying out chronovoltamperometric measurements on a suspension graphite electrode was developed. The nature and kinetics of electrode processes on dispersed graphite electrodes in 60% nitric acid were studied. It is shown that under anodic polarization of dispersion graphite electrode the complex of anodic processes occurs: the oxidation of surface of functional groups, the formation of compounds of implementation and evolution of oxygen. Maximum electrochemical reversibility of the anodic processes on the suspensions of graphite-HNO3 observed at Erev< 1.2 V, the rate of reactions of formation of compounds of the introduction of graphite and reactions involving surface functional groups on the electrode slurry increases in the range of potentials of 1.2-1.7 V. At that, the current is increase mainly causes by electrochemically reversible process of intercalation, since at the reverse cycle in the cathode area also recorded the growth of the current due to the reaction of deintercalation. An electrochemical oxidation of dispersed graphite electrode in HNO3 should be in the range of potentials from 1.2 V to 2.1 V, which will provide formation of compounds of introduction of graphite with the maximum rate and minimum power input.

For citation:Platonov M.M., Petrova G.N., Larionov S.A., Barbotko S.L. Optimization of low flammable polycarbonate based on polymeric composition for molten thread 3D-printing technology. Izv. Vyssh. Uchebn. Zaved. Khim. Khim. Tekhnol. 2017. V. 60. N 1. P. 87-94.This article contains results of composition optimization of thermoplastic polymeric mixture for the development of new low flammable material for molten thread 3D-printing technology. In order to receive qualitive polycarbonate - main material for aviation purpose functional products- a couple of tasks were solved – namely decreasing of polycarbonate melt viscosity and flammability characteristics. On the first step polybutylene terephthalate (PBT) and ABS-plastic were used for decreasing in polymeric melt viscosity. Both PBT and ABS have low viscosity melts. Incorporation of these substances into polycarbonate leads to decreasing in effective viscosity and consequently in processing temperature. On a second step the influence of halogenated fire retardant decabrombiphenyl oxide (DBDFO) in amount of 3-10% on flammability characteristics (combustibility, smoke generation, oxygen index, heat release intensity) of researched mixtures was investigated. Fire retardant incorporation allows decreasing the duration of residual burning from 22 to 1-3 s and thus, transfering material from burning to self-extinguishing type. Investigation of smoke generation shows that all mixtures belong to III group of medium fumed materials with smoke generation properties not exceeding upper level (for this group) – 200 units. Besides, it has been shown that incorporation of DBDFO permits to decrease maximum velocity of heat liberation, 18-40% reduce total amount of liberated heat during first two minutes and 26-40% increase in the time of maximum reaching. It has been figured out that increasing in fire retardant amount leads to insignificant increasing in strength properties, decreasing in tensile strength and deformation characteristics. This may be explained by the presence of fire retardant fractions having lower level strength and deformation properties. In this way basing on the conducted studies it has been shown that polycarbonate mixture comprising rheology modifier and fire retardant possesses viscosity similar as 3D-printing suitable materials (ABS, Nylon-618) and advanced flammability characteristics. Investigation results may be used for creating of aviation interior functional products satisfying to Aviation Rules standards for fire hazard and capable for recycling by 3D-printing technology.
