“Just don’t be creepy”: A phenomenological study of the experiences of men in massage therapy
Authors: Baskwill Amanda , Vanstone Meredith
Published: November 2017

Background

Societal expectations around traditional binary gender roles result in some professions being considered “men’s work” or “women’s work”. Massage therapy (MT) is one such profession that, despite being predominantly female, is joined by an increasing number of men with a desire to help others.

Methods

This descriptive phenomenological study asked male massage therapists in Ontario, Canada, about their experience of gender in their professional lives. Fourteen men shared their experiences of practice, which included discriminatory hiring and patient preferences for female practitioners. These issues resulted in difficulty establishing a clinical practice. To create a successful practice, men described the need for professionalism, clear communication, and a comfortable treatment environment.

Results and conclusions

Researchers should explore the impact of discrimination on men in MT, patient preferences based on the therapist’s gender, and the role of education in perpetuating societal heterosexual norms. Finally, as with any shift in culture, all levels of organization must take action to remove discrimination and bias within the profession of MT.

Applicability of DFT model in reactive distillation
Authors: Staszak Maciej
Published: November 2017

The density functional theory (DFT) applicability to reactive distillation is discussed. Brief modeling techniques description of distillation and rectification with chemical reaction is provided as a background for quantum method usage description. The equilibrium and nonequilibrium distillation models are described for that purpose. The DFT quantum theory is concisely described. The usage of DFT in the modeling of reactive distillation is described in two parts. One of the fundamental and very important component of distillation modeling is vapor-liquid equilibrium description for which the DFT quantum approach can be used. The representative DFT models, namely COSMO-RS (Conductor like Screening Model for Real Solvents), COSMOSPACE (COSMO Surface Pair Activity Coefficient) and COSMO-SAC (SAC – segment activity coefficient) approaches are described. The second part treats the way in which the chemical reaction is described by means of quantum DFT method. The intrinsic reaction coordinate (IRC) method is described which is used to find minimum energy path of substrates to products transition. The DFT is one of the methods which can be used for that purpose. The literature data examples are provided which proves that IRC method is applicable for chemical reaction kinetics description.
Methodeutic and the order of inquiry
Authors: Bergman Mats
Published: November 2017

Although C. S. Peirce frequently notes the importance of the branch of logic he designates “rhetoric” or “methodeutic,” he only rarely specifies what this subdivision is meant to involve. This article reassesses the role of methodeutic in Peirce’s classification of the sciences, as well as the methodical significance of this classificatory endeavor itself. The article argues that the classification of sciences is best comprehended as a distinctive phase of methodeutic investigation, which examines actual manifestations of inquiry as well as abstract principles in crafting a normatively guiding conception of the scientific venture. It is further argued that the strict hierarchy on which Peirce bases his classification needs to be tempered to allow for a more flexible ordering, in which so-called “dynamical relationships” between inquiries are considered alongside the top-down perspective of “rational precedence.”

Minahan, CL, Poke, DP, Morrison, J, and Bellinger, PM. Muscle damage and metabolic responses to repeated-sprint running with and without deceleration. J Strength Cond Res 34(12): 3423–3430, 2020—This study aimed to determine whether repeated-sprint running with deceleration aggravates markers of muscle damage or delays the recovery of performance compared with repeated-sprint running without deceleration. Fourteen male team-sport athletes performed 2 randomly ordered testing sessions on a nonmotorized treadmill with one session requiring subjects to decelerate (TMd) within 4 seconds before stopping or immediately step to the side of the treadmill belt at the completion of each sprint (TMa). Peak and mean velocities, speed decrement, blood lactate concentrations, and oxygen uptake were monitored during the repeated-sprint running protocols. Countermovement vertical jump (CMJ) performance, perceived muscle soreness, sit-and-reach flexibility, plasma creatine kinase (CK), lactate dehydrogenase (LDH), and myoglobin (Mb) concentrations were quantified immediately before and after and 45 minutes, 24 and 48 hours after repeated-sprint running protocols. Although muscle damage was indicated by increases in CK, LDH, and Mb (p ≤ 0.05) in both groups, there was no significant effect of condition (TMa vs. TMd) on any of the measured performance or physiological variables (p > 0.05). The present study indicated that the removal of deceleration from repeated-sprint running on a nonmotorized treadmill has no effect on metabolism or performance during or after repeated-sprint running or markers of muscle damage.

Fields, JB, Metoyer, CJ, Casey, JC, Esco, MR, Jagim, AR, and Jones, MT. Comparison of body composition variables across a large sample of National Collegiate Athletic Association women athletes from 6 competitive sports. J Strength Cond Res 32(9): 2452–2457, 2018—Body composition (BC) plays a critical role in sport performance and athlete health. Body size and BC have been widely studied in men's sports, with reported changes observed over time. However, a paucity of current data exists in women athletes. The purpose of this descriptive study was to measure and compare BC data for collegiate women athletes from 6 competitive sports. A total of 524 athletes from 2 National Collegiate Athletic Association institutions participated: basketball (BB; n = 95), gymnastics (GYM; n = 42), lacrosse (LAX; n = 81), rowing (ROW; n = 57), soccer (SOC; n = 188), and volleyball (VB; n = 61). Body height (BH) and body mass (BM) were measured using a stadiometer and calibrated digital scale, respectively. Body fat percentage (BF%), fat mass (FM), and fat-free mass (FFM) were assessed using air displacement plethysmography. One-way analysis of variance was used to assess differences across sports. Least squares difference post hoc analyses were performed when a significant finding (p ≤ 0.05) was identified. ROW had the highest BF% (29.9 ± 6.1%) and BB the greatest FFM (57.2 ± 6.1 kg). GYM had the lowest BM (58.9 ± 5.3 kg), FM (11.6 ± 2.6 kg), and BH (158.73 ± 2.13 cm). LAX, SOC, and VB had similar BF%. Body height was greatest for BB and VB (177.92 ± 7.55 cm, 176.79 ± 7.36 cm, respectively). These data may assist in the establishment of descriptive values for use in goal setting and exercise programming. The current data demonstrate a trend toward increased body size and BC from previous research.

Tietjen, AMJ and Devereux, GR. Physical demands of exergaming in healthy young adults. J Strength Cond Res 33(7): 1978–1986, 2019—The efficacy of whole-body exergaming (WBE) in healthy young adults remains largely unknown. This study aimed to: (a) compare the physical demands of WBE in healthy adults with traditional exercise; (b) determine whether the physical demands of WBE were reproducible. Twenty-five healthy adults (age: 22.9 ± 6.4 years; height: 1.7 ± 0.1 m; mass: 69.1 ± 12.2 kg) completed two 10-minute experimental conditions (WBE on the Xbox Kinect and treadmill walking) in a randomized cross-over design study. Whole-body exergaming produced a significant increase in the peak heart rate (138 ± 23 b·min–1), oxygen consumption (40 ± 13 ml·kg−1·min−1), metabolic equivalents (METs) (11 ± 4) compared with treadmill walking (115 ± 18 b·min–1, 25 ± 5 ml·kg−1·min−1, 7 ± 2 MET) and a modest increase in the mean heart rate (111 ± 19 b·min–1 vs. 104 ± 15 b·min–1). Whole-body exergaming produced significantly greater vertical (381 ± 118 vs. 127 ± 14 % body mass [%BM]), anterior (70 ± 22 vs. 27 ± 4 %BW), and medial (56 ± 21 vs. 7 ± 2 %BW) ground reaction forces. No difference was present in mean oxygen consumption and MET. The reproducibility of WBE was assessed in a subgroup of 11 participants (age: 24.2 ± 6.7 years; height: 1.8 ± 0.1 m; mass: 75.3 ± 10.0 kg), who completed 2 additional 10-minute WBE sessions. No difference was observed between all outcome measures. These findings indicate that WBE can reliably replicate, or surpass, the physical demands of treadmill walking and may serve as an effective addition to a health-focused exercise program.

Hodgson, DD, Quigley, PJ, Whitten, JHD, Reid, JC, and Behm, DG. Impact of 10-minute interval roller massage on performance and active range of motion. J Strength Cond Res 33(6): 1512–1523, 2019—Roller massage (RM) has been shown to increase range of motion (ROM) without subsequent performance deficits. However, prolonged static stretching (SS) can induce performance impairments. The objective of this study was to examine the effects of combining SS and RM with and without subsequent RM on ROM and neuromuscular performance. Subjects (n = 12) participated in 5 sessions: (a) SS only (SS_rest), (b) SS + RM (SS + RM_rest), (c) SS with RM at 10 and 20 minutes after stretch (SS_RM), (d) SS + RM with RM at 10 and 20 minutes after stretch (SS + RM_RM), and (e) control. For the SS conditions, the quadriceps and hamstrings received passive SS for 2 × 30 seconds each. For the SS + RM conditions, SS was applied to the quadriceps and hamstrings for 30 seconds each, and RM was performed for 30 seconds per muscle. SS_RM and SS + RM_RM conditions received an additional 30-second RM at 10 and 20 minutes after warm-up, whereas sessions without additional RM rested for the same duration. Testing measures included hip flexion (HF) and knee flexion (KF) active and passive ROM, hurdle jump height and contact time, countermovement jump height, and maximal voluntary isometric contraction force. Initial KF and HF ROM improvements provided by SS_RM and SS + RM_RM were sustained up to 30 minutes after intervention. Furthermore, SS_RM exhibited greater ROM compared with sessions lacking additional RM in active and passive HF as well as active and passive KF. Similarly, SS + RM_RM elicited greater KF and HF ROM improvements than SS_rest. In conclusion, active KF and HF ROM improvements were prolonged by additional RM, whereas neuromuscular performance remained relatively unaffected.

Anderson, D, Nunn, J, and Tyler, CJ. Effect of cold (14° C) vs. ice (5° C) water immersion on recovery from intermittent running exercise. J Strength Cond Res 32(3): 764–771, 2018—The purpose was to compare 14° C (CWI14° C) and 5° C (CWI5° C) cold water immersion after intermittent running. On 3 occasions, 9 male team-sport players undertook 12 minutes of CWI14° C, CWI5° C, or nonimmersed seated recovery (CON) after 45 minutes of intermittent running exercise. Maximal cycling performance and markers of recovery were measured before and in the 0–72 hours after exercise. Peak power output (PPO) was immediately reduced after all interventions (d = 1.8). CWI5° C was more effective at restoring PPO than CWI14° C (d = 0.38) and CON (d = 0.28) 24 hours after exercise, whereas both CON (d = 0.20) and CWI5 (d = 0.37) were more effective than CWI14° C after 48 hours. Cold water immersion (CWI) was more effective than CON at restoring PPO 72 hours after exercise (d = 0.28–0.30). Mean power output (MPO) was higher in CON compared with CWI5° C (d = 0.30) and CWI14° C (d = 0.21), but there was no difference between CWI5° C and CWI14° C (d = 0.08). CWI5° C was more effective than CWI14° C for restoring MPO to baseline levels 24 hours (d = 0.28) and 72 hours (d = 0.28) after exercise; however, CON was more, or equally, effective as CWI5° C and CWI14° C throughout. Lactate and creatine kinase concentrations were unaffected. Perceived muscle soreness remained elevated in CWI5 and CON throughout but was similar to baseline in CWI14° C after 72 hours. In conclusion, repeated bouts of exercise are initially impaired after 5 and 14° C CWI, but PPO may be improved 72 hours after exercise. Cold water immersion is not recommended for acute recovery based on these data. Athletes and coaches should use the time currently allocated to CWI for more effective and alternative recovery modalities.
Principal Component Analysis Based on Marginal Density Ratios
Authors: Shi W. , Jiang J.
Published: November 2017

Principal component analysis is a classical technique for feature extraction and dimension reduction. But it only exploits the input data and does not consider other assisting information. In the paper, we propose a novel principal component analysis based on marginal density ratios. Motivating by a naïve Bayes model, the log ratio of joint densities for features of samples is incorporated to the transform sample matrix. The acquired sample matrix is then used to calculate principal components using the singular value decomposition. Finally, the k-nearest neighbor is used as the classified method. Experimental results on synthetic and real data sets demonstrate promising performance both in accuracy and computational efficiency.

Published: November 2017

This paper reports an investigation of a very-long-term compressive-behavior evaluation of concretes containing sugarcane bagasse ash (SCBA). Initially, two different SCBA samples collected in two sugarcane plants located 1,800 km apart and 8 years apart in sampling interval were compared. From these ashes, two series of conventional and high-strength concretes were mix-designed within the Compressible Packing Model aiming for 28-day compressive strengths of 25 and 60 MPa, respectively. In the first series, a SCBA (SCBA-1) was used as a cement replacement with 10 %, 15 %, and 20 % by mass content. The different concretes were evaluated by compressive strength at 7, 28, 90, 180 days, and 1 and 10 years, and by modulus of elasticity at 28 days and 10 years. The second series of concretes was examined with similar procedures performed on the first series and another SCBA (SCBA-2, 15 % cement replacement). Compressive strength in 7, 28, 90, and 180 days, and modulus of elasticity at 28 days were evaluated. The results showed that both SCBA-1 and SCBA-2 presented similar characteristics to be considered pozzolanic materials. The effect of these ashes on the compressive strength was positive considering the cement-replacement levels used, especially for later testing ages. The results also demonstrated that all first-series concretes presented gain in compressive strength and modulus of elasticity up to 10 years of hydration. At this age, no significant differences were found in compressive strength for conventional and high-strength mixes containing SCBA compared to their respective reference mixes.

Published: November 2017

This study was conducted to identify reproducibility, repeatability, and specificity and to establish the evaluation basis through the analytical performance test of the pancreatic cancer microRNA (miRNA) diagnosis chip manufactured at the “Integrated Analysis of Next-Generation Bio-Data” in June 2016. There were 16 selected markers manufactured to be installed in the miRNA diagnosis chip exclusively for pancreatic cancer and used for analytical performance tests for the chip itself. Three analytical performance tests were performed (reproducibility, repeatability, and specificity). For the reproducibility test, the same subject had two test sessions repeated three times per each session. For repeatability analysis, two different subjects had two test sessions repeated three times per each session. Analytical specificity was analyzed by using hierarchical clustering analysis results, comparing the results of two repeated tests of normal miRNA, and the results of six repeated tests of patient group miRNA. As a result of analytical performance tests, coefficient of variance values of reproducibility and repeatability were 10 % or below, and patient groups with pancreatic cancer were significantly divided from normal groups obviously different by hierarchical clustering analysis results. Such tests confirmed that the miRNA diagnosis chip of pancreatic cancer, constructed with 16 markers, is quite suitable.

Published: November 2017

The aim of the work is the experimental testing of the Ruffier test index corrected regarding to the age of patients. Four groups of patients 6, 7, 8, and 18–20 years old with 30 subjects in each of them are tested. The procedure of the study is built on the basis of the methods of theory and procedure of physical training, mathematical simulation, pulse meter, and theory of the motor tests. Mathematical statistics and corresponding methods of computer technologies are used. A statistically significant difference between resting heart rate in the groups of adults and children of 6, 7, and 8 years old is shown (p < 0.001). According to the results of one-way analysis of variance of the two-dimensional array of data, a statistically significant difference between the values of the Ruffier index (in its classical form) is revealed in the age classes that were inspected. During the correction of the value of the Ruffier index to the age of patient, the mean value of the index on the age classes statistically proved to be equal to the mean value of the index in the group of adult patients (p = 0.834). There are no significant differences between the dynamic reaction of a heart on the physical effort regarding to the age of participants (p = 0.526).
Weak Middle-Ear-Muscle Reflex in Humans with Noise-Induced Tinnitus and Normal Hearing May Reflect Cochlear Synaptopathy
Authors: Wojtczak Magdalena , Beim Jordan A. , Oxenham Andrew J.
Published: November 2017

Chronic tinnitus is a prevalent hearing disorder, and yet no successful treatments or objective diagnostic tests are currently available. The aim of this study was to investigate the relationship between the presence of tinnitus and the strength of the middle-ear-muscle reflex (MEMR) in humans with normal and near-normal hearing. Clicks were used as test stimuli to obtain a wideband measure of the effect of reflex activation on ear-canal sound pressure. The reflex was elicited using a contralateral broadband noise. The results show that the reflex strength is significantly reduced in individuals with noise-induced continuous tinnitus and normal or near-normal audiometric thresholds compared with no-tinnitus controls. Due to a shallower growth of the reflex strength in the tinnitus group, the difference between the two groups increased with increasing elicitor level. No significant difference in the effect of tinnitus on the strength of the middle-ear muscle reflex was found between males and females. The weaker reflex could not be accounted for by differences in audiometric hearing thresholds between the tinnitus and control groups. Similarity between our findings in humans and the findings of a reduced middle-ear muscle reflex in noise-exposed animals suggests that noise-induced tinnitus in individuals with clinically normal hearing may be a consequence of cochlear synaptopathy, a loss of synaptic connections between inner hair cells (IHCs) in the cochlea and auditory-nerve (AN) fibers that has been termed hidden hearing loss.
The Fallacy of “Fallacy” and Its Implications for Contemporary Literary Theory
Authors: Altieri Charles
Published: November 2017

“The Fallacy of ‘Fallacy’” concentrates on the limitations of logical binaries in constructing arguments for literary theory. My test case is claims about intention. Theorists argue either that intentions can and must be determined or that intention is a psychological entity that cannot be determined simply from textual evidence, even when buttressed by biographical contexts. But such debates center on intentions to mean. This essay argues that literary texts are makings and not statements, so they display a relation to the world rather than assert it. It follows that when dealing with makings we usually have to look not for a specific psychological intention to mean but a way of clarifying how the display works. Therefore it may be best to equate intention with the taking of responsibility that the author assumes when deciding to publish or present materials. What is a plausible account of a series of decisions that led the author to want to make something public?

Targeted therapy of gastroenteropancreatic neuroendocrine tumours: preclinical strategies and future targets
Authors: Aristizabal Prada E T , Auernhammer C J
Published: November 2017

Molecular targeted therapy of advanced neuroendocrine tumours (NETs) of the gastroenteropancreatic (GEP) system currently encompasses approved therapy with the mammalian target of rapamycin (mTOR) inhibitor everolimus and the multi-tyrosinkinase inhibitor sunitinib. However, clinical efficacy of these treatment strategies is limited by low objective response rates and limited progression-free survival due to tumour resistance. Further novel strategies for molecular targeted therapy of NETs of the GEP system are needed. This paper reviews preclinical research models and signalling pathways in NETs of the GEP system. Preclinical and early clinical data on putative novel targets for molecular targeted therapy of NETs of the GEP system are discussed, including PI3K, Akt, mTORC1/mTORC2, GSK3, c-Met, Ras–Raf–MEK–ERK, embryogenic pathways (Hedgehog, Notch, Wnt/beta-catenin, TGF-beta signalling and SMAD proteins), tumour suppressors and cell cycle regulators (p53, cyclin-dependent kinases (CDKs) CDK4/6, CDK inhibitor p27, retinoblastoma protein (Rb)), heat shock protein HSP90, Aurora kinase, Src kinase family, focal adhesion kinase and epigenetic modulation by histone deacetylase inhibitors.
Long noncoding RNAs: emerging players in thyroid cancer pathogenesis

Published: November 2017

Thyroid cancer continues to be the most common malignancy of endocrine glands. The incidence of thyroid cancer has risen significantly over the past 4 decades and has emerged as a major health issue. In recent years, significant progress has been achieved in our understanding of the molecular mechanisms of thyroid carcinogenesis, resulting in significant diagnostic, prognostic and therapeutic implications; yet, it has not reached a satisfactory level. Identifying novel molecular therapeutic targets and molecules for diagnosis and prognosis is expected to advance the overall management of this common malignancy. Long noncoding RNAs (lncRNAs) are implicated in the regulation of various key cellular genes involved in cell differentiation, proliferation, cell cycle, apoptosis, migration and invasion mainly through modulation of gene expression. Recent studies have established that lncRNAs are deregulated in thyroid cancer. In this review, we discuss extensively the tumor-suppressive (for example, LINC00271, MEG3, NAMA, PTCSC1/2/3, etc.) and oncogenic (for example, ANRIL, FAL1, H19, PVT1, etc.) roles of various lncRNAs and their possible disease associations implicated in thyroid carcinogenesis. We briefly summarize the strategies and mechanisms of lncRNA-targeting agents. We also describe the potential role of lncRNAs as prospective novel therapeutic targets, and diagnostic and prognostic markers in thyroid cancer.

Published: November 2017

The development of self-compacting concrete (SCC) is a revolutionary landmark in the history of the construction industry. Incorporation of fibres further enhances the properties, especially those related to the post-crack behaviour of SCC. The fibres used in the study are 12 mm long chopped glass fibre, carbon fibre and basalt fibre. The volume fractions of fibre taken are 0·0, 0·1, 0·15, 0·2, 0·25 and 0·3%. The research comprised two stages: the first stage consisted of the development of an SCC mix design of M30 grade; in the second stage, different fibres, such as glass, basalt and carbon fibres, were added to the SCC mixes and their fresh and hardened properties were determined and compared. Carbon fibre-reinforced SCC (FRSCC) exhibited the best performance followed by basalt FRSCC and glass FRSCC in the hardened state, whereas it exhibited the poorest performance in the fresh state due to its high water absorption. Glass FRSCC exhibited the best performance in the fresh state. This study concludes that, in terms of overall performance, optimum dosage and cost, basalt fibre is the best option for improving the overall quality of SCC.
Ceramic waste powder: from landfill to sustainable concretes

Published: November 2017

Incorporating solid waste materials in concrete has three advantages – the immediate environmental benefit of recycling a material from landfills, reducing the negative impact of cement production and preserving natural resources. Ceramic waste powder (CWP), produced during the process of polishing ceramic tiles, is dumped in landfills and can cause soil, air and groundwater pollution leading to serious environmental problems. CWP is mainly composed of silicon dioxide and aluminium oxide (>80%), making it a good candidate in concrete manufacturing. This study investigated the use of CWP in producing conventional (CV) concrete and self-compacting concrete (SCC). CWP was used as a partial cement replacement: by 10, 20, 30 and 40% in CV mixtures and by 28 and 57% in SCC mixtures. Fresh properties, compressive strength development and durability characteristics of the different concretes showed that CWP could be successfully used as a partial cement replacement. The optimum replacement for CV mixtures was found to depend on the concrete strength grade. For the 25 MPa mixture, the optimum replacement level was 10–30%, while it was 20 or 30% for the 50 MPa mixture. For SCC mixtures, as far as strength is concerned, a 28% replacement level can be used while, for fresh and durability characteristics, both 28 and 57% are acceptable.
The Impact of Tourism Policy Environments on Operation of the Cultural Tourism Governance and Its Policy Outcome: A Case of the Resident’s Council in Gamcheon Culture Village
Authors:   The Tourism Sciences Society Of Korea, Lee Sang-Ho
Published: November 2017

The resident’s council of Gamcheon Culture Village, one of famous representative cultural tourism places in Busan, is established by bylaw for the operation and development of the village. This council depends on a collaborative network of various policy actors(i.e., residents, artists, professors, and public officers). It plays leading roles in developing the village as a cultural tourism site and in improving the inhabitants’ quality of lives. This study aimed to identify unique influencing factors of cultural tourism governance that were established by the council and to analyze the impacts of the governance operation and policy outcome. For these purposes, this study measured influencing factors of governance using policy environment variables. Specifically, the influencing factors were consisted of social environment factor such as a fundamental element of governance, institutional environment factor that was essential for operating governance, and tourism environment factor that facilitates the governance operation. The results showed that the efficient operation of cultural tourism governance was influenced by all three factors. Especially, both the social environment and operation of the governance were found to be an influencing factor of policy outcome. By comparing these findings with previous studies in the tourism field, this study also suggested a few lessons considered when we establish and operate cultural tourism governance.
Job-Education Mismatch Possibility Resolved in the Hospitality Industry: Which Is More Applicable, Job Mobility Theory or Job Competitiveness Theory?
Authors:   The Tourism Sciences Society Of Korea, Lee Eun-Soo
Published: November 2017

This study identified the difference of job-education mismatch according to demographics and job characteristics to see if job-education mismatch in the Korean hospitality industry is a temporary phenomenon or a long-lasting problem. Job mobility theory based on human capital theory supports the theory that job-education mismatch is a temporary mismatch because overeducated workers rapidly get promoted or move to higher level jobs. However, job competitiveness theory describes job-education mismatch as a long-lasting problem with negative effects on productivity. The data were collected from employees in five deluxe hotels throughout Seoul. After removing any spoiled submissions, 291 surveys were analyzed. The results showed that job-education mismatch was reduced as age, tenure, and internal/external career mobility increased to a certain extent, but it was proved a chronic problem in the overall results. It was found that job-education mismatch in the Korean hospitality industry can be a persistent phenomenon rather than a temporary mismatch. Furthermore, it was found that job-education mismatch is better explained by job competitiveness theory than it is by job mobility theory. In the final section, theoretical and practical implications of these results are suggested.

Published: November 2017

One of the important things in reactor safety is the value of inherent safety parameter namely reactivity coefficient. These inherent safety parameters are fuel and moderator temperature coefficients of reactivity.  The objective of the study is to obtain the change of those reactivity coefficients as a function of fuel burn up during the cycle operation of AP 1000 reactor core. Fuel and moderator temperature coefficients of reactivity and in addition moderator density coefficient of reactivity were calculated using SRAC 2006 and NODAL3 computer codes. Cross section generation of all core material was done by SRAC 2006 Code. The calculation of core reactivity as a function of temperature and burn up were carried out using NODAL3 Code. The results show that all reactivity coefficients of AP 1000 reactor core are always negative during the operation cycles and the values are in a good agreement to the design. It can be concluded that the AP 1000 core has a good inherent safety of its fuelKeywords: reactivity coefficient, burn up, AP1000, NODAL3. ANALISIS PERUBAHAN KOEFISIEN REAKTIVITAS AKIBAT FRAKSI BAKAR TERAS REAKTOR AP1000 MENGGUNAKAN NODAL3.  Salah satu hal yang sangat penting dalam analisis kecelakaan pada reactor daya adalah koefisien reaktivitas untuk mengontrol daya reaktor.

Die Planung einer prozesstechnischen Anlage ist ein interdisziplinärer Prozess zwischen Gewerken, wie Verfahrensauslegung, Rohrleitungsplanung, Elektro-, Mess- und Regeltechnik, um einige zu nennen. Diese Gewerke generieren in den Projektphasen Information, die Grundlage für die Planung zeitlich nachfolgender Diszi­plinen ist. Bis heute ist es nicht gelungen, dass sich Anlagenbauer, Owner´s Engineering, Instandhaltung und Betreiber auf ein Standarddatenmodell einigen, mit dem alle effizient und wirtschaftlich planen und die Anlage betreiben können. Deshalb wird in diesem Beitrag gezeigt, wie unterschiedliche Datenmodelle so kombiniert werden, dass es den einzelnen Gewerken weiterhin möglich ist, in ihren eigenen CAE-Werkzeugen zu arbeiten und dennoch über automatisierte Schnittstellen ein konsistenter Datenstand sichergestellt ist.
Compensação De Tensão Trifásica Em Cargas Sensíveis Baseada Em Um Sistema De Controle Repetitivo E Mínimos Quadrados

Published: November 2017

Este trabalho propõe a utilização de um controle repetitivo para restaurar de forma dinâmica a tensão em cargas sensíveis conectadas à rede elétrica. O controle intrinsecamente é capaz de mitigar a distorção harmônica e é estruturado apenas por uma função de transferência. Desta forma, não há necessidade da aplicação de filtros harmônicos seletivos. Além disso, o sistema de controle é capaz de trabalhar em referências senoidais e, assim, evita a necessidade de utilizar a transformação de Park. O algoritmo de mínimos quadrados recursivo também é incluído ao sistema de controle, a fim de assegurar a sincronização das tensões a serem restauradas. O projeto dos parâmetros de controle, juntamente com a estabilidade do sistema são discutidos. Os resultados experimentais são obtidos com uma montagem de um compensador série trifásico. Os cenários das tensões com distúrbios são os mesmos para os resultados experimentais e simulados. Os resultados corroboram o uso do método proposto e encorajam novas investigações.

Published: November 2017

Este artigo tem por escopo apresentar o estudo e desenvolvimento de um conversor CC-CC não isolado de três portas, adequado à integração em um único estágio de conversão: um banco de baterias, um conjunto de painéis fotovoltaicos e o link CC. A topologia proposta apresenta um conversor boost de alto ganho baseado na versão bidirecional da célula de comutação de três estados na qual se tem integrado um banco de baterias e um conjunto de painéis fotovoltaicos com capacidade para gerar um barramento CC de 200V em um único estágio de processamento. A característica bidirecional da topologia permite que os painéis fotovoltaicos carreguem as bateiras e alimente a carga dependendo da potência gerada pelo PV. No caso de ausência de sol, o banco de baterias supre a carga. Outra importante característica deste conversor é a comutação suave em modo ZVS para todas as chaves. Foi desenvolvido um protótipo experimental com potência nominal de 500W de forma a validar todo o embasamento teórico e de simulação apresentados. O conversor desenvolvido foi submetido a três condições: o fluxo de energia da bateria para a carga, do painel fotovoltaico para a carga e do painel para o banco de baterias, sendo obtido o rendimento de 94,18%, 96,09% e 94,67% respectivamente para cada condição. Além disso, as formas de ondas experimentais e de simulação para cada condição e o comparativo de rendimento de topologias, também são apresentados. O alto ganho e o rendimento alcançado nesta topologia, a torna uma forte solução quando há necessidade de elevar a tensão a partir de baterias ou painéis fotovoltaicos, quando os valores fornecidos por estes geralmente são de 12V, 24V ou 48V.
Compensação Série Com Mínima Injeção De Potência Ou De Tensão Baseada Em Controle Repetitivo

Published: November 2017

Este trabalho propõe a utilização de um controle repetitivo para restaurar de forma dinâmica a tensão aplicada a cargas sensíveis e conectadas na rede elétrica. Além de compensar afundamentos e elevações de tensão, o controle proposto pode corrigir distorções harmônicas. Ainda, é capaz de trabalhar em referências senoidais, e assim, evita a necessidade do emprego de transformadas $dq$. Um algoritmo de mínimos quadrados recursivos também é incluído no sistema de controle, a fim de assegurar a sincronização das tensões injetadas. O projeto dos parâmetros de controle, juntamente com a estabilidade do sistema são discutidos ao longo do trabalho. Além dessas funcionalidades, este trabalho tem como principal objetivo analisar dois tipos diferentes de inserção de tensão na rede por meio do compensador série. No primeiro, a injeção de tensão está sincronizada com a tensão da rede durante a falta, enquanto que o segundo insere a tensão com um mínimo de potência ativa. Ambos os tipos de inserção produzem as tensões de referência por meio do controle repetitivo. Os resultados de simulações e experimentais são apresentados e corroboram a eficácia do método.

Authors: Francisco Oliveira da Silva Nilton , Lobo Heldwein Marcelo , José Perin Arnaldo
Published: November 2017

Este trabalho apresenta o estudo e o desenvolvimento de um conversor wireless para carregar supercapacitores, que utiliza redes de imitância para sintonizar o primário e o secundário de um transformador com baixo coeficiente de acoplamento. A frequência de operação do conversor é a frequência de ressonância das redes de imitância e, nesta condição, a rede opera como um conversor V/I (a fonte de tensão na entrada é convertida em fonte de corrente na saída). A rede de imitância do primário alimenta o transformador com corrente de amplitude constante. A rede de imitância no secundário assegura a comutação suave do retificador e corrente constante com baixa ondulação na saída do conversor para toda faixa de operação da tensão na carga. Conversores com esta característica são adequados para alimentar cargas como supercapacitores e baterias.
Migração, Migrações

Dra. Eunice Ribeiro Durham, antropóloga, dona de um extenso e brilhante currículo marcou positivamente a produção acadêmica brasileira com seus trabalhos sobre família, migração e movimentos sociais nas décadas de 1970, 1980 e 1990. Atualmente, é pesquisadora e membro do Conselho do Núcleo de Pesquisa de Políticas Públicas da Universidade de São Paulo (NUPPS). Nesta entrevista, Eunice Durham nos releva um pouco dos bastidores de suas pesquisas e retoma alguns temas presentes em sua obra “A caminho da cidade”, publicado em 1984
Significados da chegada do PT à Presidência da República: reflexões iniciais
Authors: Braga Maria do Socorro , Pasquarelli Bruno
Published: November 2017

Em 2002, a eleição do candidato do PT, Luiz Inácio Lula da Silva para a Presidência da República marcou indelevelmente a história política do Brasil. Afinal, pela primeira vez no contexto republicano nacional um partido de esquerda, com uma liderança oriunda de segmento popular, alcançou o cargo mais importante e cobiçado do sistema político brasileiro. Entretanto, é sabido que a vitória do PT para o Executivo, no segundo turno daquele pleito, não lhe garantiu uma maioria no Congresso Nacional, tendo que compor maiorias amplas e heterogêneas para garantir maior grau de governabilidade. Também teve que ampliar o leque de partidos em sua coligação eleitoral, levando para o governo federal representantes de setores de amplo espectro político ideológico e perfil social. E seu bom desempenho ao longo daquele primeiro mandato, lhe garantiria a reeleição no pleito de 2006, agregando mais partidos classificados como de direita ao seu campo de ação nas arenas governativas.
Da bolsa família à renda básica: limites e possibilidades de uma transição
Authors: Silva Josué Pereira da
Published: November 2017

Pelo menos desde 2006, o senador Eduardo Suplicy vem defendendo, em diversos textos, a tese de que o programa Bolsa Família será o caminho para se instituir a Renda Básica de Cidadania no Brasil (Suplicy, 2006; 2007; 2008; 2010). O Programa Bolsa Família beneficia atualmente quase 13 milhões de famílias ou 45 milhões de pessoas e é o principal programa de transferência direta de renda vigente no Brasil; o crescente número de beneficiários incorporados ao programa desde sua criação em 2003,1 certamente contribui para que haja certo otimismo quanto a sua possível universalização, justificando em parte a tese de que ele caminharia em direção à instituição da Renda Básica de Cidadania. Ademais, se em seu início os debates e as experiências de transferência direta de renda no Brasil foram, em grande medida, impulsionados pelo debate internacional em torno da ideia de renda básica, atualmente, pela dimensão que assumiu, o Programa Bolsa Família se tornou uma das grandes esperanças daqueles que postulam a instituição da Renda Básica Universal (Van der Veen, 2010).
Vulnerabilidade e (Sub)Cidadania na sociedade brasileira – Entrevista com Lúcio Kowarick
Authors: Trindade Thiago Aparecido , Ferro Maria Caroli Tiraboschi
Published: November 2017

Autor do livro “Viver em Risco” (2009), obra vencedora do Prêmio Jabuti em 2010 na categoria de Ciências Humanas, Lúcio Kowarick é, indubitavelmente, um dos intelectuais brasileiros mais importantes da atualidade. Mestre em Ciências Sociais pela Diplôme D’études Approfondies (Paris) e Doutor em Sociologia pela Universidade de São Paulo, Kowarick foi um autor de destaque no acalorado debate sobre marginalidade e dependência no decorrer da década de 1970, ao lado de intelectuais como Fernando Henrique Cardoso, Rui Mauro Marini, Francisco de Oliveira, Paul Singer, dentre outros. Sua contribuição mais decisiva no campo acadêmico certamente foi na perspectiva do “urbano”, numa época em que o terreno teórico sobre urbanização, pobreza e exclusão social ainda estava sendo desbravado no Brasil e na América Latina. Publicado originalmente em 1979, o livro “A Espoliação Urbana” avançou de forma considerável no debate sobre as precárias condições de vida das classes trabalhadoras nas grandes cidades do capitalismo periférico. Ao longo de sua obra, dedicou atenção também à análise dos movimentos sociais e os desafios inerentes à ação coletiva, com o foco sempre voltado para as mobilizações populares que lutam por melhores condições de vida no espaço de moradia. Por estas e por muitas outras razões, Kowarick pode ser considerado um dos grandes especialistas no tema da (Sub)Cidadania no contexto intelectual da América Latina. Na sala de reuniões do Departamento de Ciência Política da USP, Lúcio Kowarick nos concedeu a entrevista reproduzida abaixo, que, apesar de breve, traz pontos de grande relevância teórica e política para a compreensão da problemática relacionada à cidadania na sociedade brasileira atual. Nossos agradecimentos ao Professor Lúcio, que desde o momento em que recebeu nosso convite se mostrou muito disposto e interessado em contribuir para a presente edição da Idéias.
