Catalytic Hydrothermal Liquefaction of Microalgae using Fe-MCM 41 Catalyst in Presence of Carbon Monoxide
Authors: Sharma R. , Tiwari A.K. , Singh A. , Sharma N.
Published: February 2019

Among the various types of biomass, microalgae have a potential to become a significant energy source for the production of third generation biofuel. The hydrothermal liquefaction is the direct biomass-to-liquid conversion route carried out in the hot compressed water with or without the presence of a catalyst. In this study, the process pressure and temperature is reduced, but at a lower temperature, bio-oil yield is not high enough to make hydrothermal liquefaction an economical technique. Thus, Fe-MCM 41 catalyst was used to increase the bio-oil yield at low temperatures (250 ºC). This catalyst increased the total bio-oil yield from 42.7 to 61.28 % in hydrothermal liquefaction of Chlorella pyrenoidosa. The bio-oil yield (%) of oil 1, 2 & 3 were 24.72, 17.08 & 19.48, respectively obtained at 250 ºC by using catalyst. Moreover, use of catalyst also resulted in the decrease in oxygen and nitrogen contents of bio-oil and consequently increases in its heating value.

Authors: Blades David C. A. , Copley Claudia , Lee Kasey
Published: February 2019

A new system of storing adult Odonata (damselfly and dragonfly) specimens is described and compared to existing storage systems. The major design innovation is the use of tongue and groove (“zipper lock”) resealable polyethylene envelopes manufactured to fit the standard index card and specimen arrangement currently used in major collections. Other design improvements include low-cost, adhesive-free specimen trays and glass-top drawers built to fit in standard-dimension Cornell insect cabinets. Comparisons of materials and designs with other available systems are presented and discussed. Finally, examples are presented of this new system's applicability to other collections such as Lepidoptera and Archeology.
The Transformative Power of Student-Led Natural History Collections Clubs
Authors: Gerdes Cheyenne , Harris Kari M , Beas-Moix Mireia , Marsico Travis D
Published: February 2019

Many colleges and universities maintain herbaria or natural history collections. Natural History Collections Clubs (NHCCs) are registered student organizations (RSOs) capable of improving conditions in these collections, many of which are threatened by a lack of funding, minimal curatorial staff, and inadequate institutional support. Student involvement through NHCCs can improve conditions in collections at academic institutions by providing volunteers, promoting outreach, increasing funding, and generating enthusiasm in administration, students, and the community. In this paper, we explain the need for such organizations, outline the process of establishing an NHCC, and provide case studies from successful organizations. We also describe a developing network for NHCCs and summarize what has been accomplished by these organizations to date.

Authors: Rahadianto Naufal Arief , Maarif Syamsul , Yuliati Lilik Noor
Published: February 2019

Congestion is a common problem in big cities, including Jakarta as a capital of Indonesia. Increasing the number of vehicles in Jakarta is not proportional to the growth of roads. This makes the road become inconducive. The use of public transportation is a solution to solve this problem. While public intention in using public transportation is still considered low. Research on the intention of using public transport is still less. Based on this, further research is needed that focuses on the intention to use public transportation. This study explores the intention to use public transport that focus on Transjakarta busway while considering several factors in Jakarta, Indonesia. This study describe intention behavior of Transjakarta potential user, study and explores the relationship between intention to use Transjakarta and other latent factors, including personal norms, social influence, environment impact, and perceived quality. The empirical data were drawn from 190 potential users of Transjakarta in Jabodetabek that still use private vehicle, car or motorbike in daily activity using questionnaire method. Structural equation model (SEM) technique is used to analyze the conceptualized relationship model. The result reveal that personal norms, social influence, and perceived quality significantly affect potential users’ intention behavior. From the empirical result, managerial implications were discussed.
To be or to consume? That is the question: Semiotics Analysis of Advertisements of largest Retail Supermarkets in Brazil
Authors: Da Silva Isabella Gil Barbosa , Chaves Eduardo de Paula e Silva
Published: February 2019

The study of representations and images involved in advertising campaigns is a recurrent resource of marketing managers. Therefore, understanding and analyzing advertisements and their semiotics becomes an important source of research. In this context, the following research problem arises: what are the complementarity, contrariety and contradiction relations that carry the advertisements of supermarket retailers? Thus, the main objective is to analyze semiotic advertising of national supermarket chains through the constitution of a semiotic square. For that, the greimasian methodology (Greimas, 1973) was used, which sustains a generative path of meaning, where the relations existing between the signifiers produce signification. We investigated the advertisements of the largest retail supermarket brands in Brazil, by price, product and people variables. Thus, the semiotic square was created for the advertising of supermarket retailers in Brazil.
On Process Management (PM) The applicability of Michael Hammer’s theory in Argentina
Authors: Bello Hernán , Viltard Leandro Adolfo
Published: February 2019

This article explores the applicability of Hammer’s theories on Operational Innovation (OI), Operational Excellence (OE) and processes, on firms of different industrial sectors and sizes, located in Argentina. The hypothesis of this study -which was corroborated- suggests that the manager’s role is supported by what is called Process Management (PM), which deals with performance gaps in a given period of time. In this context, OE, OI and processes’ understanding becomes an important constituent of the management activity. Through the implementation of a holistic PM-based perspective in many more organizations it is possible to boost results, achieve superior levels of performance and offer the right customer value. Specifically, a process is represented by a sequence of activities. It allows installing, following and measuring an operation, and isbased on five enablers and four capabilities that are explained in this study. This is an exploratory and descriptive work, with a qualitative methodology. Also, this study has a not experimental/transversal design. It is based on Hammer’s theories on the matter, which were complemented with executives/managers' interviews of different multinationals and local firms located in Argentina. debt crowdfunding in Latin America and Mexico. Implications for lenders, researchers and policy-makers are also discussed.
Application of a proposed TLS model in a Lean Productive System
Authors: Dias Rui Manuel Ferreira , Silva Luis Diogo , Tenera Alexandra
Published: February 2019

The current market, becoming more rigid, forces companies to search continuously for innovation and improvement of their processes and products as a way to keep competitive and gain strategic advantages. Due to the global economic crisis, more and more companies try an approach through new management methodologies that allow better performances in terms of earning, profit and cost reduction. The present article proposes an integrated TOC (Theory of Constraints), Lean and Six-Sigma (TLS) model, with the objective of improving continuously a productive system, although it shows flexibility to be applied in other kinds of systems. The model synergistically integrate the best practices found in existing TOC, Lean and Six-Sigma models. The proposed model derivatives mainly from Eliyahu Goldratt’s TOC model of the “5 focus steps” and TLS model “Ultimate Improvement Cycle”, developed by Bob Sproull. The proposed TLS model was tested on an important Portuguese Manufacture. The implementation of a first continuous improvement cycle was completed and a second cycle began. The main results obtained by the implementation of the TLS model were extremely satisfactory.

Authors: Faria Catarina , Antunes Henedina , Pontes Teresa , Antunes Ana , Martins Sofia , Carvalho Susana
Published: February 2019

Background

Venous thromboembolism (VTE) – which includes deep venous thrombosis (DVT) and pulmonary embolism (PE) – has been increasingly recognized in the pediatric population. The estimated incidence is 0.07–0.14 cases per 10,000 children. Most cases are associated with two or more risk factors. Medium and long-term complications include recurrence and post-thrombotic syndrome (PTS).

Objective

To characterize the adolescent population with the diagnosis of DVT of lower limbs in a tertiary hospital, regarding its clinical presentation, associated risk factors, treatment and outcome.

Methods

Retrospective analysis of adolescents with the diagnosis of DVT of lower limbs in our hospital for a period of 7 years.

Results

Eight patients were identified; seven were females; median age was 15 years. The main symptoms were local pain and edema. Left lower limb was affected in six patients. PE occurred in two cases. Positive family history of venous thromboembolism was found in five patients. Seven patients had at least two identifiable risk factors. Combined oral contraceptive pill use was the most common (seven patients). Factor V Leiden mutation was found in three patients and protein C deficiency in one. Iliac vein compression syndrome was diagnosed in one patient. The median time for discharge was 8 days. Election treatment was enoxaparin followed by warfarin, for a median period of 10.9 months. Three patients developed PTS.

Conclusions

Although uncommon, VTE is an emerging reality in adolescents, particularly in females using oral contraceptive pills. Appropriated prevention strategies and treatment are required as most orientations are extrapolated from adults.

Theoretical analysis of LC-refining – pressure screening systems in TMP
Authors: Rubiano Berna Jorge Enrique , Sandberg Christer , Martinez Mark , Olson James
Published: February 2019

LC refining of mechanical pulps has proven to save energy in the production of TMP pulps. However, the specific role of LC refining as part of a TMP system has not been thoroughly studied since it is difficult to conceive any particular system at industrial-scales and impractical at pilot-scales. In this study, pressure screening and LC refining models that describe fibre length distributions, together with correlations to predict refining power were used to model three basic refining systems. From the simulation results, the impact of important variables such as reject ratio, refiner gap and refining net-power was studied. Performance curves of length-weighed average fibre length were generated from simulation results and were used to assess each system behaviour and also to make comparisons between systems. Data from an industrial scale TMP mill sub-system was gathered and compared to simulation results showing relative errors between 0–18 % on the predicted variables.
Effect of nobiletin on experimental model of epilepsy
Authors: Yang Baowang , Wang Jing , Zhang Ni
Published: February 2019

Background

The effects of nobiletin, a plant-derived flavonoid was examined against pentylenetetrazole (PTZ)-induced seizures. The study also aimed to assess whether nobiletin potentiated the effects of antiepileptic drug clonazepam (CZP).

Methods

PTZ (92 mg/kg, subcutaneous) was used to induce seizures in mice. Treatment groups (n = 18/group) received nobiletin (12.5, 25, or 50 mg/kg) via oral gavage for 6 consecutive days and 45 min prior to PTZ injection. CZP (0.015-2.0 mg/kg) was administered 15 min prior to PTZ. Skeletal muscle strength was assessed by measuring grip strength and Chimney test was performed to study the motor performance in animals. TUNEL assay was done to study neuro-apoptosis. RT-PCR and Western blot analysis were performed for assessment of mRNA and protein expressions.

Results

Nobiletin and CZP improved muscle strength and motor coordination and reduced seizure severity significantly. The administration of nobiletin and CZP, individually or in combination, downregulated seizure-induced increases in apoptotic cell count and apoptotic protein expression, modulated the expression of gamma-aminobutyric acid (GABA)A and glutamate decarboxylase 65 and restored the glutamate/GABA balance. Nobiletin and CZP administration significantly upregulated phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) signaling.

Conclusion

Nobiletin exerted protective effect against seizures by regulating signaling pathways associated with epileptogenesis and potentiated the effects of CZP.
Eye Position Error Influence over “Open-Loop” Smooth Pursuit Initiation
Authors: Buonocore Antimo , Skinner Julianne , Hafed Ziad M.
Published: February 2019

The oculomotor system integrates a variety of visual signals into appropriate motor plans, but such integration can have widely varying time scales. For example, smooth pursuit eye movements to follow a moving target are slower and longer lasting than saccadic eye movements and it has been suggested that initiating a smooth pursuit eye movement involves an obligatory “open-loop” interval in which new visual motion signals presumably cannot influence the ensuing motor plan for up to 100 ms after movement initiation. However, this view is contrary to the idea that the oculomotor periphery has privileged access to short-latency visual signals. Here, we show that smooth pursuit initiation is sensitive to visual inputs, even in open-loop intervals. We instructed male rhesus macaque monkeys to initiate saccade-free smooth pursuit eye movements and injected a transient, instantaneous eye position error signal at different times relative to movement initiation. We found robust short-latency modulations in eye velocity and acceleration, starting only ∼50 ms after transient signal occurrence and even during open-loop pursuit initiation. Critically, the spatial direction of the injected position error signal had predictable effects on smooth pursuit initiation, with forward errors increasing eye acceleration and backward errors reducing it. Catch-up saccade frequencies and amplitudes were also similarly altered ∼50 ms after transient signals, much like the well known effects on microsaccades during fixation. Our results demonstrate that smooth pursuit initiation is highly sensitive to visual signals and that catch-up saccade generation is reset after a visual transient.

SIGNIFICANCE STATEMENTSmooth pursuit eye movements allow us to track moving objects. The first ∼100 ms of smooth pursuit initiation are characterized by smooth eye acceleration and are overwhelmingly described as being “open-loop”; that is, unmodifiable by new visual motion signals. We found that all phases of smooth pursuit, including the so-called open-loop intervals, are reliably modifiable by visual signals. We injected transient flashes resulting in very brief, spatially specific position error signals to smooth pursuit and observed very short-latency changes in smooth eye movements to minimize such errors. Our results highlight the flexibility of the oculomotor system in reacting to environmental events and suggest a functional role for the pervasiveness of visual sensitivity in oculomotor control brain regions.

Originally intended as a performance piece, #flyingwhileback is a heart-wrenching, sometimes whimsical, recalling of the process of boarding an airplane in a Black body. Bordering the genre of speculative fiction, this poem illustrates one of the many ways the Black body is seen as violent and threatening by simply existing. The poem is intended to recount many of my own experiences as well as challenge the authority of the Transportation Security Administration and the ways they engage with Black people.
“Black Human” and “Remember”
Authors: Hastings Rachel N.
Published: February 2019

The MenStroll Cycles is a dramatic poemplay examining the sociopolitical state of Black men in America. Written, produced, and curated by Rachel N. Hastings, The MenStroll Cycles uses literary, performance, and digital art to interrogate antiBlack social conditions and to educate audiences about the historical and cultural cycles leading to criminalization. As a fast-paced, rhythmic journey through Black intelligencia, Hastings's performance is inspired by the deaths of Trayvon Martin and Michael Brown, and movements like Black Lives Matter, which highlight a pattern of racial crises emerging around issues of police and community relations, institutional and systemic exclusion, and the disproportionate number of Black men in prison. Rarely are Black men and women represented as allies against a common foe. Hastings counters the notion that Black people cannot advocate and critique one another, while offering a critical Blackademik narrative about the use of performance as an artistic act of political resistance.

El objetivo de esta investigación fue determinar la producción de madera de cedro en sistemas agroforestales (SAF) con café, utilizando un modelo de predicción del volumen comercial obtenido en el área de estudio, así como la rentabilidad que se genera por la venta de café, madera y el pago por servicios ambientales (PPSA). El estudio se realizó en el cantón de Pérez Zeledón, provincia de San José, Costa Rica. Se establecieron 30 parcelas temporales de muestreo de 1 000 m2 en SAF con cedro entre cinco y 17 años de edad. Se evaluó el crecimiento en diámetro (DAP) y la altura comercial (HC) de la especie, así como el manejo del SAF (actividades, insumos y rendimientos) y producción de café mediante entrevista al productor. Los modelos obtenidos permitieron predecir el volumen comercial (m3 árb-1) en función de la edad (R2=88,7%), el DAP (R2=90,3%) y HC (R2=97,2%). La producción de café promedio de los sitios muestreados fue de 26 fanegas ha-1 año-1. A los 17 años de edad del cedro se obtuvo una producción de 1,04 m3 árb-1 (92,13 m3 ha-1) de madera en pie, lo cual representó un aporte financiero de 81% del valor actualizado neto (VAN) del SAF en el período de análisis. Los indicadores financieros estimados permiten concluir que el SAF café-cedro es rentable ya que generó un VAN positivo de ₡8 198 601,5, una tasa interna de retorno (TIR) de 16%, la cual fue superior al costo del dinero (tasa de descuento de 6,1%) y una relación B/C de 1,34.
Student Evaluation of International Interaction and Communication Opportunities at University
Authors: Kompanets Victoria , Väätänen Juha
Published: February 2019

This paper addresses the university campus environment for international interaction and communication by studying self-evaluation of local and international students. The research aims to determine which factors of the formal and informal learning environment as well as social interaction outside university influence students’ quality perceptions of opportunities for international interaction and communication at university and how these factors affect student evaluations. The study developed and tested a measurement scale to assess the quality of international interaction and communication opportunities in higher education. The research is based on a quantitative survey of 200 students mainly from Nordic countries and Russia, and represent both domestic and international student perspectives. Item-by-item, factor and multiple regression methods were used for data analysis. Multicultural interaction and local community engagement are important driving factors of student quality evaluation of international interaction and communication. Multicultural interaction and worldview perspectives exchanges in class and ease of making friends with local students and international students had significant impact on quality perception of international interaction and communication for both international and local students. In order to improve students’ opportunities for international interaction and communication, universities should provide their students with regular opportunities to interact with one another during social campus events, clubs, and committees as well as extracurricular multicultural events organised by stakeholders.

Authors: Mittal Shraddha , Marlowe Lauren , Blakeslee Samantha , Zieniuk Gregory , Doshi Samir , Gray Bobbi Jo , Bowen Melissa , Oleaga Leslie , Carbone Kelly , Aumaier Brenna L. , Taylor April , Joffe Mark
Published: February 2019

BACKGROUND AND OBJECTIVES:

The American Academy of Pediatrics 2014 bronchiolitis guidelines recommend against the routine use of continuous pulse oximetry (CPO) because it has been implicated in prolonging the length of stay (LOS). At our institution, infants admitted with bronchiolitis were monitored by using CPO during the entire hospital stay and intermittent desaturations <90% appeared to delay discharge. This quality improvement initiative was designed to reduce the LOS by decreasing the use of CPO in stable infants with nonsevere bronchiolitis.

METHODS:

The quality improvement project was implemented on the inpatient units of 2 community hospitals during the 2016 and 2017 bronchiolitis seasons. In cycle 1 (January 2016 to April 2016), the bronchiolitis pathway from the associated quaternary children’s hospital was used to (1) limit the use of CPO to patients with severe bronchiolitis and those at high risk for apnea or severe disease, (2) discontinue CPO as patients improved and stabilized, and (3) standardize discharge criteria. In cycle 2 (November 2016 to April 2017), the clinical pathway was adopted. The main outcome measure was LOS, measured from the time of the admission order to the time of the discharge order. Process measures included compliance with the interventions.

RESULTS:

The project included 373 patients, 180 preintervention and 193 postintervention. The average LOS decreased by 20 hours, from 53 hours at baseline to 33 hours in cycle 2. No adverse events were noted, and there was no significant change in the number of emergency department revisits and readmissions within 7 days.

CONCLUSIONS:

In our study, LOS was successfully reduced in bronchiolitis patients by using a clinical pathway that limited CPO to patients with severe bronchiolitis and those at risk for severe disease or apnea.

Authors: Masonbrink Abbey R. , Stancil Stephani , Reid Kimberly J. , Goggin Kathy , Hunt Jane Alyce , Mermelstein Sarah J. , Shafii Taraneh , Lehmann Amber G. , Harhara Haleema , Miller Melissa K.
Published: February 2019

BACKGROUND AND OBJECTIVES:

Many hospitalized adolescents are at increased risk for pregnancy complications due to an underlying medical condition, however sexual risk assessment is not consistently performed in this setting. While adolescents and their parents are supportive of sexual health discussion in the inpatient setting, a thorough understanding of factors that influence provision of this care among pediatric hospital physicians is lacking. This formative information is needed to facilitate efforts to improve and standardize clinical care provision. Our objective is to assess the frequency and factors that influence the provision of adolescent sexual and reproductive care by pediatric hospitalists.

METHODS:

We performed a cross-sectional computerized survey of hospitalists at 5 pediatric hospitals who cared for ≥1 adolescent (14–21 years old) in the past year. Sexual and reproductive care practices were assessed by using a 76-item novel survey informed by the theory of planned behavior. We used descriptive statistics to summarize the data.

RESULTS:

Sixty-eight pediatric hospitalists participated (49% response rate): 78% were women and 65% were aged <40 years. Most (69%) reported treating >46 adolescents annually, including many who are at an increased risk for pregnancy complications due to teratogenic medication use or a comorbid condition. A majority felt that sexual and reproductive services are appropriate, although many endorsed barriers, including concern about follow-up after emergency contraception (63%) and time constraints (53%). Most reported insufficient knowledge regarding contraception (59%), desired contraception education (57%), and were likely to increase contraceptive provision if provided education (63%). Hospitalists rarely provided condoms or referral for an intrauterine device.

CONCLUSIONS:

Pediatric hospitalists frequently care for adolescents who are at risk for pregnancy complications and generally agree that reproductive care is appropriate in the inpatient setting. With these findings, we highlight the critical need for effective comprehensive reproductive health service interventions that are tailored to address the numerous actionable barriers identified in this study.
Evaluating the HEADS-ED Screening Tool in a Hospital-Based Mental Health and Addictions Central Referral Intake System: A Prospective Cohort Study
Authors: Clark Sharon E. , Cloutier Paula , Polihronis Christine , Cappelli Mario
Published: February 2019

OBJECTIVES:

We evaluated the use of a mental health (MH) screening tool in a hospital-based centralized MH referral telephonic intake process. The tool is used to guide psychosocial screening in several domains: home; education; activities and peers; drugs and alcohol; suicidality; emotions, thoughts, and behaviors; and discharge resources (HEADS-ED). We wanted to understand the use of the tool to guide next step in care decision-making over the telephone.

METHODS:

Intake workers used the HEADS-ED tool to guide the assessment processes, identified areas of MH need, and made decisions about next step in care. We completed a retrospective chart review of all callers to the intake system over 4 months to gather initial decision at intake and subsequent steps in treatment. χ2 and analysis of variance tests were used to examine differences between HEADS-ED scores and next step in care.

RESULTS:

A total of 674 patients aged 3 to 19 years (mean age = 11.7 years, SD = 0.6; girls = 50.0%) called for services. Significant mean differences were found on total HEADS-ED scores between treatment options (F4,641 = 75.76; P < .001). Decision validity indicated that 86% (n = 506 of 587) of initial referrals matched treatments that were actually received. Uptake of the tool was 100%, and interrater reliability indicated strong agreement between raters (intraclass correlation coefficient = 0.82; P < .001).

CONCLUSIONS:

With our results, we support the use of the HEADS-ED tool in a telephone-based MH intake system to help guide the initial assessment and inform decision-making about fit of next step in care, both within the health center–based MH system and in the community.
Trait and state anxiety as factors of threshold and tolerance to experimentally induced pain
Authors: Petrova B. , Mineva K. , Petkova M. , Nikolov V. , Minev M. , Strebkova R.
Published: February 2019

Pain is an experience that has physical, psychological and social aspects. Sensitivity to pain is individual and depends on psychological factors. Studies have shown that anxiety is associated with the perception of experimentally induced pain. PURPOSE: The purpose of the present study is to examine the relationship between anxiety, threshold and tolerance to experimentally induced pain in healthy persons. METHODS: 35 healthy persons at the age from 19 to 39, 20 women and 15 men were examined. Methods: Spielberger’s questionnaire, Cold pressor test, Visual Analog Scale for Pain, Descriptive statistics, Correlation analysis, Mann-Whitney’s Test. RESULTS: Significant differences in tolerance to pain were identified depending on the levels of state anxiety (U=12.5, Р=0.037). The state anxiety was greatly related to the intensity of the pain experienced. (Spearman rho=0.49, P=0.008). Significant differences were not found in threshold, tolerance and intensity of pain depending on the levels of trait anxiety in the examined people. CONCLUSIONS: The increased levels of state anxiety in healthy persons exposed to experimentally induced pain suggest a weaker endurance to pain and perceiving it as stronger.
High-throughput microalgae cultivation with adjustable LED-module applying different colours for Nannochloropsis and Chlorella microcultures
Authors: Kiss B. , Németh Á.
Published: February 2019

Utilization of algae includes both macroalgae for human consumption dating back to thousands of years, as well as the application of microalgae in health promoting dietary supplements. The autotrophic growth of microalgae is slow, but can be accelerated by optimizing their cultivation conditions. Efficiency optimizations for time and economy should be performed in many parallel experiments. A new high-throughput microalgae cultivation method is presented here, applying 24-low-well microplate with varying illumination, in which the cell growth is followed via evaluation of scanned images. A strain of the genus Nannochloropsis and two Chlorella vulgaris species have been chosen as well described and frequently applied model organisms in order to test the recently developed cultivation system. In these scaled down experiments, the custom design lighting panel was tested by studying the effect of the colour of illumination on cell growth kinetics. RGB LEDs (i.e. light emitting diodes, red: 622 nm, green: 528 nm, and blue: 467 nm) were used individually or together providing red, green, blue, and white colours. While the effect of light’s colour on algae growth was evaluated, also the new system was proven to be suitable for comparing maximal growth rates for different microalgae strains. While the tested two Chlorella isolates reached 1.2–1.4 g l–1 concentrations, the Nannochloropsis strain reached 1.4 g l–1 final cell dry weight, and specific growth rates were observed between 0.58–0.62 day–1.

Contrary to what has been long held that censorship began during the revolución libertadora, I make the case that censorship legislation was first passed during the democratic government of Arturo Frondizi (term of office 1958-1962). This legislation prioritized the projection of a poster-image of the nation, the protection of Catholic values, and the promotion of shared national beliefs. This early legislation paved the way for the instauration of film censorship in 1968—as well as the regulations on censorship approved up until March 1976, when a new dictatorship took over—, but was met with antagonism from several different social actors at that time. Several resonant cases illustrate the dynamic censorship-freedom of expression that characterized the 1958-1976 period.
O poeta desfolha a bandeira: Literatura e resistência em Torquato Neto
Authors: Brasileiro Marcus
Published: February 2019

Torquato Neto (1944 – 1972) –poeta, jornalista e cineasta—foi um dos participantes da Tropicália, “movimento” artístico e cultural que ocorreu no Brasil na segunda metade da década de 1960. A poesia de Torquato Neto foi marcada por um gesto de rebeldia que, ao mesmo tempo que apontava para uma mudança radical das mentalidades dos jovens em relação aos modelos de comportamento social e familiar, colocava uma forte resistência política e ideológica ao modelo autoritário que a ditadura militar implantara no Brasil. Neste trabalho, a relação entre linguagem e resistência será discutida a partir dos poemas de Torquato Neto. Pensar esta relação traz à consciência para leitores contemporâneos alguns modelos de subjetivação presentes na cultura brasileira e os gestos discursivos utilizados por artísticas para desconstruir formações ideológicas autoritárias.

Modelling Transformative Education
Authors: Webb Rebecca , Kirby Perpetua
Published: February 2019

This article is a call to rebalance and broaden contemporary education to include a focus on both conformity and transformation. It includes an overview of three different models of education, relating to different educational purposes. Two emphasise conformity in knowledge acquisition
– 'mastering knowledge' and 'discovering knowledge' – as well as a third, 'not-knowing', that emphasises transformation in terms of what it is possible to know, to do and to be. The article explores the complementarity of these different models, and the need for further conversations
to ensure a greater balance between conformity and transformation within educational institutions.
Shear behaviour of fire-damaged reinforced-concrete beams
Authors: Xing Qiong , Liao Jiehong , Chen Zhi , Huang Wei
Published: February 2019

This paper experimentally evaluates the shear behaviour of seven reinforced-concrete (RC) beams following fire damage. Three sides of each beam were subjected to an ISO 834-1 standard fire for 2 h and then the beams were tested in shear loading after air cooling. The effects of the shear/span ratio and the heated positions on the shear behaviour of RC beams were investigated. The test results showed that after fire damage, the shear-bearing capacities and the shear stiffness of the RC beams decreased, while the ultimate deformations of the beams increased. With respect to RC beams, the reduction in the flexural-bearing capacity was larger than that in its shear-bearing capacity when its compression zone was subjected to fire. The study of the shear-transfer mechanism indicated that arch action is one of the main contributors to the shear capacity of a RC beam after fire damage. Based on the plastic limit theory, a simplified approach for evaluating the residual shear strength is presented in this study.
Clinical importance and sex differences of the femoral anteversion angle
Authors: Kapur Eldan , Dracic Anel , Gracic Edinela
Published: February 2019

Introduction: The Femoral angle of anteversion (FAA) is responsible for the medial and anterior direction of the femoral neck and therefore the femoral head towards the acetabulum. The aim of this study was to determine the difference in FAA between male and female samples, the correlation between the FAA and biomechanically relevant parameters and to provide a review of relevant clinical features related to FAA.

Methods:  We included 100 human dry femora and analyzed FAA, Angle of Inclination (AI), Femoral Head Diameter (FHD), Femoral Biomechanical Length (FBL) and Linear Condylar Parameters (Epicondylar Breadth Width (EBW), Lateral Condyle Depth and Medial Condyle Depth). The measurements were made using a goniometer, sliding calipers and pieces of colored string.

Results: Mean FAA values were 9.84±7.97° and 8.72±8.23° for the male and female samples, respectively (p<0.05). FAA and AI in both male and female correlated negatively (-0.076), while there was a positive correlation between FAA and FHD (0.069), FAA and FBL (0.072), FAA and EBW (0.029), while the correlation was negative between FAA and LCD (-0.072), FAA and MCD (-0.063).

Conclusion: The difference in FAA between male and female femora was found to be significant. This finding may help better understanding such as hip impingement, total hip arthroplasty failure, and design of femoral endoprosthesis parts.
User Involvement of People with Mild Disabilities in Technology Innovations: Does It Make a Difference?
Authors: Borch Anita , Strandbakken Pål
Published: February 2019

In this study, we explored the role of people with mild forms of visual, hearing, physical, and cognitive impairments in innovation processes. Our research questions are: do the product evaluations by people with mild disabilities differ from those given by people without reported disabilities? If so, how? The analysis is based on eight focus group interviews conducted in Norway in 2016, in which 60 participants were asked to evaluate 11 energy-efficient product ideas. Four of the focus groups (two of men and two of women) were recruited based on the criteria of being mildly disabled. The remaining groups (two of men and two of women) had no such clause. The research results are ambiguous, indicating that the evaluations of new innovation by mildly disabled people correspond with those made by people without reported disabilities in some aspects and differ in others. However, the small size of the sample studied in this article suggests that the research results must be regarded as preliminary. Overall, the study reveals some interesting observations to be confirmed and disconfirmed in further research.
Dressing a Demanding Body to Fit In: Clean and Decent with Ostomy or Chronic Skin Disease
Authors: Laitala Kirsi , Klepp Ingun Grimstad
Published: February 2019

This article discusses what kind of strategies people with a stoma or various chronic skin conditions, such as psoriasis or atopic dermatitis, use to find clothes that fit and enable them to fit in. Based on qualitative interviews in Norway, we study how they manage to dress with a demanding body, a poor market and limited economic resources. This includes describing how purchases take place, which clothes fit, how much clothing is needed, and which laundry practices are used. Their main strategy was to reduce the requirements for their own appearance rather than to cleanliness and body odours. If they were unable to appear appropriately dressed, as a minimum odourless and stain free, they reduced their participation in social life.

A WIRELESS SECURE KEY DISTRIBUTION SYSTEM WITH NO COURIERS: A ONE-TIME-PAD REVIVAL
Authors: Barbosa Geraldo Alexandre
Published: February 2019

Among the problems to guarantee secrecy for in-transit information, the difficulties involved in renewing cryptographic keys in a secure way using couriers, the perfect secrecy encryption method known as One-Time-Pad (OTP) became almost obsolete. Pure quantum key distribution (QKD) ideally offers security for key distribution and could revive OTP. However, special networks that may need optical fibers, satellite, relay stations, expensive detection equipment compared with telecom technology and the slow protocol offer powerful obstacles for widespread use of QKD.
Classical encryption methods flood the secure communication landscape. Many of them rely its security on historical difficulties such as factoring of large numbers - their alleged security sometimes are presented as the difficulty to brake encryption by brute force. The possibility for a mathematical breakthrough that could make factoring trivial are poorly discussed.
 This work proposes a solution to bring perfect secrecy to in-transit communication and without the above problems. It shows the key distribution scheme (nicknamed KeyBITS Platform) based on classical signals carrying information but that carry with them recordings of quantum noise. Legitimate users start with a shared information of the coding bases used that gives them an information advantage that allows easy signal recovery. The recorded noise protects the legitimate users and block the attacker's access.
 This shared information is refreshed at the end of each batch of keys sent providing the secret shared information for the next round. With encryption keys distilled from securely transmitted signals at each round OTP can be revived and at fast speeds.

Published: February 2019

This article presents an annotation and discussion of our own clinical observation of a high-risk multiple pregnancy after in vitro fertilization in a patient with tuboperitoneal infertility. We report a case of early prenatal diagnosis of a rare malformation of a single fetus in dichorionic twin pregnancy (pentalogy of Cantrell). The feasibility of cumulative assessment of the risks of assisted reproductive technology complications to determine the tactics of management and intensive observation during pregnancy, as well as the use of invasive intrauterine interventions for multiple pregnancy to reduce perinatal risks is discussed.
