Authors: Tayyab Haroon , Ahmed Chaudhry Nasir , Sadiq Muhammad Ali Ayaz
Published: December 2019

Objective: To evaluate the safety and efficacy of Suprachoroidal Triamcinolone Acetonide (SCTA) injection in patients with treatment resistant Diabetic Macular Edema (DME).

Methods: This was a prospective non randomized interventional study conducted in the vitreoretinal department of Al Ehsan Welfare Eye Hospital, Lahore, Pakistan from March 2018 to September 2018. A total of 24 eyes of 24 patients were included. Baseline Best Corrected Visual Acuity (BCVA), Intra Ocular Pressure (IOP) and Central Subfield Thickness (CST) was recorded. After SCTA, patient was followed up at one and three months and same clinical parameters were recorded again and results analyzed.

Results: Out of 24 patients, 11(45.83%) were males and 13(54.16%) were females. Mean pre injection CST was 636.5 ± 200.11 um. Mean pre injection BCVA was 0.8 ± 0.24 on ETDRS chart. Mean post injection CST at one and three months was 304.54 ± 67.43 and 302.66 ± 66.93 um. Mean post injection BCVA at one and three months was 0.47 ± 0.3 and 0.45 ± 0.27 on ETDRS chart. The results were statistically significant for pre and post injection CST at both one and three months (p-value < 0.00001). Pre and post injection BCVA was also statistically significant (p-value < 0.05).

Conclusion: Preliminary evidence suggests that SCTA is well tolerated and may help in improving functional and structural outcomes of treatment resistant DME.

Search Under Accumulated Pressure
Authors: Alizamir Saed , de Véricourt Francis , Sun Peng
Published: December 2019

The paper “Search Under Accumulated Pressure” explores how time pressure in the form of task accumulation might affect the information-gathering process of a decision maker. Decision makers often need to balance the benefit of improving their belief about the best choice against the cost of acquiring more information. In many instances, the cost to acquire additional information depends on the size of the accumulated workload. The paper formulates this problem as a partially observable Markov decision process and characterizes the optimal control policy. The analysis reveals that the highest workload that the decision maker is willing to sustain may increase in the middle of the information search. This runs counter to the more intuitive argument that, as the search for information on a task progresses, the decision maker becomes less willing to sustain a high level of workload.
Arrhythmogenic right ventricular cardiomyopathy: contemporary challenges of diagnosis and management
Authors: Driver Liam
Published: December 2019

Arrhythmogenic right ventricular cardiomyopathy is a rare but potentially lethal condition that predominantly affects the right ventricle although a left or biventricular form is now recognised. The condition can present in a variety of ways from palpitations to aborted sudden cardiac death. It is characterised by the replacement of healthy myocardium with fatty infiltrates and is progressive in nature. There is no single test for this condition and diagnosis can be difficult – relying on a diagnostic criteria to aid diagnosis. This score system uses criteria based on ECG findings, evidence of arrhythmia, structural changes detected on echocardiogram and MRI, histopathology and family history. Treatment is initially medicine based, to suppress ventricular arrhythmias; however, patients may require device therapy, ablation or cardiac transplantation. There are recognised psychological implications for patients with arrhythmogenic right ventricular tachycardia and they may require support to come to terms with the changes that a diagnosis can bring.

Authors: Soares Rhea SA , Lima Suzinara BS , Eberhardt Thaís D , Rodrigues Liane R , Martins Robson S , Silveira Lidiana BTD , Alves Paulo JP
Published: December 2019

Objective:

To identify the skin temperature in different body areas of hospitalised individuals in the surgical unit, without risk of developing a pressure ulcer (PU).

Methods:

A descriptive, correlational and cross-sectional study, carried out May–October 2017, in a surgical unit of a university hospital in southern Brazil. Temperature was measured at the bony prominences including scapula, elbow, trochanters and heels, on both sides of the body, as well as occipital and sacral regions.

Results:

A total of 230 patients took part in the study. All regions of the body measured presented differences in temperatures. The sacral region presented the highest mean temperature (34.2±0.1°C). Patients (aged 18–59 years) had higher skin temperatures in the sacral region than older patients (aged 60–88 years). There was a symmetry in temperatures on both sides of the body. There was a low degree of correlation between age, room temperature, room humidity and skin temperature in some body regions.

Conclusion:

The study established mean values for skin temperature in specific body regions in patients without risk of developing a PU, hospitalised in a surgical unit. It also demonstrates how skin temperature can be used as a clinical parameter in practice to support the prevention of PUs.

Authors: Aloweni Fazila Abu Bakar , Ang Shin Yuh , Chang Yee Yee , Ng Xin Ping , Teo Kai Yunn , Choh Andrea Chaeu Lin , Goh Ivy Hui Qi , Lim Siew Hoon
Published: December 2019

Objective:

To evaluate the use of an infrared thermography device in assessing skin temperature among category I pressure ulcer (PU) and/or suspected deep tissue injuries (SDTI) with intact skin.

Methods:

An observational cross-sectional study design was used. Adult inpatients (cases) who had a category I PU or suspected deep tissue injury (skin intact) on the sacral or heel during the study period (March to April 2018) were recruited. Patients without a PU were also recruited to act as control. Thermal images of the patient's PU site and non-PU site were taken within 24 hours of PU occurrence. Thermal images of the control patients (no PU) were also taken. Each PU case was matched to three control patients in terms of age, gender, race and anatomical sites. All thermal images were taken using a portable CAT S60 Thermal Imaging Rugged Smartphone (Caterpillar Inc., US) that provided readings of the skin temperature in degrees Celsius.

Results:

A total of 17 cases and 51 controls were recruited. Among the cases, the mean difference in skin temperature between the PU site (mean: 31.14°C; standard deviation [SD]: 1.54) and control site within the cases (mean: 28.93°C; SD: 3.47) was significant (difference: 2.21±3.66°C; p=0·024). When comparing between all cases and controls, the mean temperature difference was non-significant. When comparing between the category I PU and suspected deep pressure injury cases, the mean difference was also non-significant.

Conclusion:

Using infrared thermography technology at the bedside to measure skin temperature will support the clinical diagnosis of patients with skin types I to III. However, there is a need for a more accurate and objective measurement to identify and diagnose early category I PU or suspected deep tissue injury in adult patients with darker skin types 4 and above, enabling early initiation of preventive measures in the hospital acute care setting.

Published: December 2019

Sedimentary phosphate (SP) was used as an adsorbent for the removal of 2-nitrophenol from aqueous solutions in an attempt to investigate (the feasibility of) its application (to) in wastewater purification.Â  The adsorbent was characterized by X-ray diffraction (XRD), IR spectroscopy, Fluorescence X and BET.Â  The results indicated that the SP (was) is francolite (Ca10 (PO4,CO3)6F2) and mesoporous. The effect of the adsorption time and the pH of the solution were studied. The pseudo-first-order, pseudo-second-order and intraparticle diffusion models were used to fit adsorption data in the kinetic studies. The equilibrium isotherms were determined using the Langmuir, Freundlich and Dubinin-Radushkevich models. The results show that the Dubinin-Radushkevich isotherm had better agreement with the 2-nitrophenol adsorption on SP with a correlation coefficient of 0.98, an equilibrium adsorption capacity of 633 mg. g-1 and a corresponding contact time of 2 h. The results imply that intraparticle diffusion could be summarized as the basic rate-controlling mechanisms during 2-nitrophenol adsorption on SP.
Phase retrieval using axial diffraction patterns and a ptychographic iterative engine
Authors: Wagatsuma Yoshiya , Shimobaba Tomoyoshi , Yamamoto Yota , Hoshi Ikuo , Kakue Takashi , Ito Tomoyoshi
Published: December 2019

We propose a phase retrieval method using axial diffraction patterns under planar and spherical wave illuminations. The proposed method uses a ptychographic iterative engine (PIE) for the phase retrieval algorithm. The proposed approach uses multiple diffraction patterns. Thus, adjusting the alignment of each diffraction pattern is mandatory, and we propose a method to adjust the alignment. In addition, a random selection of the measured diffraction patterns is used to further accelerate the convergence of the PIE-based optimization. To confirm the effectiveness of the proposed method, we compare the conventional and proposed methods using a simulation and optical experiments.

Authors: Zhang Gang , Wu Xuqiang , Li Shili , Liu Wei , Fang Shasha , Zuo Cheng , Zhang Wujun , Yu Benli
Published: December 2019

We propose a miniaturized optical fiber Fabry–Perot probe for high temperature measurement (up to 1000°C). It is simply fabricated by fusion splicing a short section of polarization-maintaining photonic crystal fiber (PMPCF) with a single-mode fiber (SMF). The interface between the core of the SMF and air holes of the PMPCF, and the end face of the PMPCF work as the mirrors. The pure silica core of the PMPCF is employed as the sensing element. Experimental results show that the probe has a high thermal stability and the temperature sensitivity reaches up to 15.34 pm/°C, which is not affected by the length of the PMPCF. The linearity of temperature response is as high as 99.83%. The proposed sensor has promising prospects in practical applications due to simple fabrication process, low cost, compact size, and excellent repeatability.

Three-dimensional visualization of microvasculature from few-projection data using a novel CT reconstruction algorithm for propagation-based X-ray phase-contrast imaging
Authors: Zhao Yuqing , Ji Dongjiang , Li Yimin , Zhao Xinyan , Lv Wenjuan , Xin Xiaohong , Han Shuo , Hu Chunhong
Published: December 2019

Propagation-based X-ray phase-contrast imaging (PBI) is a powerful
nondestructive imaging technique that can reveal the internal detailed
structures in weakly absorbing samples. Extending PBI to CT (PBCT)
enables high-resolution and high-contrast 3D visualization of
microvasculature, which can be used for the understanding, diagnosis
and therapy of diseases involving vasculopathy, such as cardiovascular
disease, stroke and tumor. However, the long scan time for PBCT
impedes its wider use in biomedical and preclinical microvascular
studies. To address this issue, a novel CT reconstruction algorithm
for PBCT is presented that aims at shortening the scan time for
microvascular samples by reducing the number of projections while
maintaining the high quality of reconstructed images. The proposed
algorithm combines the filtered backprojection method into the
iterative reconstruction framework, and a weighted guided image
filtering approach (WGIF) is utilized to optimize the intermediate
reconstructed images. Notably, the homogeneity assumption on the
microvasculature sample is adopted as prior knowledge, and therefore,
a prior image of microvasculature structures can be acquired by a
k-means clustering approach. Then, the prior image is used as the
guided image in the WGIF procedure to effectively suppress streaking
artifacts and preserve microvasculature structures. To evaluate the
effectiveness and capability of the proposed algorithm, simulation
experiments on 3D microvasculature numerical phantom and real
experiments with CT reconstruction on the microvasculature sample are
performed. The results demonstrate that the proposed algorithm can,
under noise-free and noisy conditions, significantly reduce the
artifacts and effectively preserve the microvasculature structures on
the reconstructed images and thus enables it to be used for clear and
accurate 3D visualization of microvasculature from few-projection
data. Therefore, for 3D visualization of microvasculature, the
proposed algorithm can be considered an effective approach for
reducing the scan time required by PBCT.

and low group velocity of the PhC make it possible to attain a significant phase shift in low-power high-frequency pulses traveling through the nonlinear arm. A control wave is utilized to increase the phase shift by the cross-phase modulation phenomenon. A complete study on the phase variation is performed by varying various parameters such as powers and pulse widths of the probe and control signal. The study is used to determine the length of the nonlinear arm to calculate the transfer characteristic of the device. The transfer characteristic shows a successful inversion operation in the power range of 28–60 mW for a pulse width of 3 ps. The overall dimension of the device is found as

Engineering the absorption spectra of thin film multilayer absorbers for enhanced color purity in CMY color filters
Authors: Rana Ahsan Sarwar , Zubair Muhammad , Anwar Muhammad Sabieh , Saleem Murtaza , Mehmood Muhammad Qasim
Published: December 2019

A thin film of dielectric material on metal provides a simple and cost-effective platform for absorbing light of a specific wavelength that can be desirably tuned by tailoring the thin film thickness. This property of controlled absorption can lead to realizing various exciting applications such as absorbers and color filters. The primary concern, however, in using such multilayer configurations for color filtering is color purity, which is generally low as compared to patterned resonant structures that employ costly nanofabrication techniques. We report a practical design technique to achieve filters of cyan, magenta, and yellow (CMY) with enhanced color purity, polarization-insensitive, and angle-insensitive functionalities. The design involves dielectric thin film layer sandwiched between an ultra-thin metal-layer and ground plane. We demonstrate several multilayer material configurations that provide advantages over the current state-of-the-art color filters in terms of color purity. The proposed devices can find applications in high-resolution color printing, digital imaging, holographic displays, and sensing.
Towards a pedagogy of deviance
Authors: Millares Myrtle D.
Published: December 2019

This article engages the narratives of three Toronto hip-hop artists to explore the pedagogical possibilities revealed through the processes of performance identity construction. By immersing themselves in hip-hop communities, artists learn ways of knowing and negotiating their place at the interstices of the normative frameworks that underlie their unique combinations of cultural contexts. Artists’ stories reveal how they bring themselves into being through movement and sound. These narrations of identity become indicative of an artist’s style through performative iterations embedded with the opportunity for enacting difference. For hip-hop artists, deviating from performative expectations is not a mere possibility, but formative intention in the tradition of the African American practice of Signifyin(g), as delineated by Henry Louis Gates, Jr. Conversations with hip-hop artists invite reflection on what we could accomplish through a music education pedagogy that cultivates creative deviancy that reveals, breaks open and overturns limiting conventions.
‘Frail but Fearless’: Dichotomies of femininity and strength at the New York Hippodrome, 1905–17
Authors: Merriman Rebecca
Published: December 2019

This article examines two women who performed athletic feats at the New York Hippodrome between 1905 and 1917, arguing that their approaches to costume and bodily display were integral to their widespread critical and public acclaim. The women examined are lion tamer Claire Heliot and swimmer and diver Annette Kellerman. I contend that these performers occupied a difficult position within the early-twentieth-century entertainment industry. The type of mainstream spectacle that the Hippodrome provided, combined with strict societal ideas of what constituted femininity and masculinity, created an environment that was not conducive to the success of athletic women.

Their unusual acts therefore required them to negotiate their public image in such a way that emphasized their inherent femininity. Their costume was an essential element of this negotiation as it exposed the audience to a kind of woman with whom they were already familiar. Claire Heliot did this by occupying a traditional domestic womanhood that sharply contrasted with her dangerous lion-taming act, and Annette Kellerman emphasized her beauty through the sexually charged display of her body in form-fitting costumes and swimsuits. In addition to analyses of their costumes, critical responses to their performances are taken into consideration as evidence of these women’s success as performers. This article highlights how costume and the body can be used as tools to alter identity and reinforce gender norms for the purposes of subverting the physical expectations of women.
Every stain a story: The many dirty undershirts of John McClane in Die Hard
Authors: Dierker Urs A. Georg
Published: December 2019

Men’s upper body underwear and the depiction of grime, dirt and blood on costumes have a long tradition in Hollywood films. This article explores the 34 undershirts worn by Bruce Willis and his stuntman in the 1988 action film Die Hard from the points of view of the maker, designer, actor, curator and spectator. The image of McClane and the undershirt became iconic in their depiction of a white, working-class, heroic masculinity. One of the many undershirts used in the film was donated to the Smithsonian’s National Museum of American Culture costume collection. This one artefact and the 33 ‘lost’ doubles hold more clues to the undershirt’s past than the obvious connection to a major star; the exhibited object also brings the viewer into physical proximity with the art of Hollywood filmmaking. This article queries the different ‘authenticities’ of the garment, from its material believability as evidence of the character’s progression through the film, to its cultural signification legitimized by the perspectives of the makers and audiences, to its role as artefact authenticated by the museum and/or viewer. Analysis is correspondingly divided into costume in context, costume in production, costume as film image and costume as artefact.
Sex and macrocyst formation in Dictyostelium
Authors: Bloomfield Gareth
Published: December 2019

Sex in Dictyostelia involves a remarkable form of cannibalism in which zygotes attract large numbers of surrounding amoebae and then ingest them. Before they are consumed, the attracted amoebae help the zygote by synthesising an outer wall around the aggregate that traps them inside and helps to protect the mature developed zygotic structure, the macrocyst. Competition between cells vying to contribute genetically to zygotes and through to the next generation seems likely to have promoted the evolution of several unusual features of dictyostelid sex: individual species often have more than two mating types, increasing haploid cells’ chances of matching with a compatible partner, and fusion of many gametes to form transient syncytia allows cytoplasmic mixing and lateral transmission of mitochondrial genomes. This review will summarise recent advances in our understanding of mating-type determination, gamete fusion, and inheritance in Dictyostelium, and highlight the key gaps in our understanding of this fascinating set of phenomena.
Microbiome management in the social amoeba Dictyostelium discoideum compared to humans
Authors: Farinholt Timothy , Dinh Christopher , Kuspa Adam
Published: December 2019

Social amoebae and humans use common strategies to orchestrate their interactions with the bacteria in their respective environments and within their bodies. These strategies include the elimination of bacteria by phagocytosis, the establishment of mutualistic interactions, the elaboration of physical barriers, and the deployment of innate immune cells. Many of the molecular mechanisms that humans and social amoebae employ differ, but there are striking similarities that may inform studies in each organism. In this topical review we highlight the similarities and consider what we might learn by comparing these highly divergent species. We focus on recent work in Dictyostelium discoideum with hopes of stimulating work in this area and with the expectation that new mechanistic details uncovered in social amoebae-bacteria interactions will inform microbiome management in humans.

The Dictyostelium discoideum model system
Authors: Escalante Ricardo , Cardenal-Muñoz Elena
Published: December 2019

When we set out to organize this Special Issue, we faced the difficult task of gathering together a large variety of topics with the unique commonality of having been studied in a single model organism, Dictyostelium discoideum. This apparent setback turned into a wonderful opportunity to learn about an organism as a whole, which provides a more complete understanding of life processes, their natural meaning and their changes during evolution. From studies dedicated almost exclusively to cell motility, differentiation and patterning, the versatility of D. discoideum has allowed in recent years the expansion of our knowledge to other areas, including cell biology and many others related to human diseases. The present collection of papers can be considered as a journey throughout the mechanisms of life, where D. discoideum acts as a very special tourist guide.

Declive y resiliencia industrial en la periferia mediterránea europea. Análisis territorial y sectorial en la Comunitat Valenciana durante la década de 2010
Authors: Membrado-Tena Joan Carles , Hermosilla-Pla Jorge , Fansa Ghaleb
Published: December 2019

El descenso del sector industrial en la economía de la Comunitat Valenciana durante las dos últimas décadas ha sido muy acusado, ya que pasó del 25% del VAB en 1995 a menos del 17% en 2013. Este declive se explica por los cambios estructurales que tuvo que afrontar con la llegada del nuevo milenio para adaptarse a los nuevos patrones de producción y consumo propios de la globalización, que se vieron agravados por la crisis financiera de 2007. A partir de un enfoque por sectores y, a la vez, por territorios, se lleva a cabo un análisis de la evolución reciente de la industria valenciana. Se observa como el modelo predominante de esta industria sigue siendo el distrito industrial endógeno, si bien cada vez es más presente la empresa multinacional, en especial en las aglomeraciones urbanas. Se aprecia que, después de lustros de caída, desde 2012 hacia aquí el sistema fabril valenciano ha mostrado una fuerte resiliencia que permite pensar en un futuro escenario industrial más positivo.

Authors: Abdullah Hend H. A. M. , Hussein Hany A. , Abd El-Razik Khaled A. , Barakat Ashraf M. A. , Soliman Yousef A.
Published: December 2019

Background and Aim: Q fever is a zoonotic disease caused by Coxiella burnetii. Cattle, sheep, and goat are the main reservoir of C. burnetii. In Egypt, the epidemiological data about C. burnetii in camels are limited. Therefore, the current study was conducted to identify C. burnetii infection in camels by different molecular tools and to estimate its seropositivity through the detection of anti-C. burnetii antibodies in camel sera. Materials and Methods: Blood samples were collected 112 from camels in Giza and Cairo Provinces, Egypt. All blood samples were screened by trans-quantitative polymerase chain reaction (trans-qPCR) for C. burnetii and positive samples subjected to standard PCR using the superoxide dismutase enzyme coding gene of C. burnetii. Sera of studied camels were examined for the presence of antibodies against C. burnetii using enzyme-linked immunosorbent assay. Results: Out of 112 camels, 19 were positive for C. burnetii by qPCR with an overall prevalence of 16.9% (18.6% in Giza and 15.1% in Cairo Provinces, respectively). The seroprevalence of anti-C. burnetii IgG antibodies in the examined camels was 4.5% (5/112). Conclusion: Trans-qPCR assay is a rapid and sensitive tool for the detection of C. burnetii in acute stage. Camels should be considered one of the major reservoirs for C. burnetii in Egypt.

Este estudo teve por objetivo investigar o processo educativo ambiental em uma escola pública de Ensino Fundamental no município de Capistrano-CE. Trata-se de pesquisa analítica de abordagem quantitativa, realizada com 40 alunos que responderam a um questionário contendo perguntas sobre conceitos e práticas de educação ambiental. Os resultados reforçam que a prática ambiental na escola e aulas diferenciadas são fundamentais para a consolidação de atitudes socioambientais e que a escola, como promotora de conhecimento e cidadania, algumas vezes esquiva-se não atendendo aos anseios socioambientais de seus alunos.

Concepts, practices of environmental education and citizen training in school

The objective of this study was to investigate the environmental education process in a public elementary school in the municipality of Capistrano-CE. This is an analytical research with a quantitative approach, carried out with 40 students from a municipal public school. A questionnaire containing questions that addressed ambiental education (EA) concepts and practices was applied to the participants. The results indicate that the teaching and practice of EA in schools are important contributors to social practices, being the environmental practice in school and differentiated classes as fundamental to social and environmental practices. It is, therefore, evidenced that the school, as promoter of knowledge and citizenship, sometimes dodges, failing to meet the socioenvironmental desires of its students.

Published: December 2019

Neste ensaio a abordagem dos conflitos ambientais em ‘zonas de sacrifício’ expressa o alinhamento conceitual e epistemológico de educação ambiental com o pensamento freireano e com o “ecologismo dos pobres” apoiados na Ecologia Política. A América Latina e o Brasil são territórios que tem em seu processo histórico a exploração da natureza e do ser humano, e consequentemente a emergência dos conflitos socioambientais. Objetivamos apontar algumas possíveis propostas para pensar qual agenda política pode ser comum em práticas de educação ambiental realizadas em zonas de sacrifícios. Consideramos que o campo crítico é o que melhor legitima as abordagens para a educação ambiental ‘desde del Sur’ comprometida com o enfrentamento das desigualdades e com a travessia para novas relações mais justas e emancipatórias do Bem Viver.

Travels for environmental education 'from the south': one Common critical policy agenda in 'sacrifice zones' as Brazil and latin america

In this test the approach of the environmental conflicts in „zones of sacrifice‟expresses the conceptual alignment and epistemológico of environmental education with the thought freireano and with “ecologismo of the poor persons” supported in the Political Ecology. The Latin America and Brazil are territories that there has in his historical process the exploration of the nature and of the human being, and consequently the emergence of the conflicts socioambientais. We aim to point to some possible proposals to think which political diary can be common in practices of environmental education carried out in zones of sacrifices. We think that the critical field is what better legitim the approaches for the environmental education „from del Sur‟ compromised with the enfrentamento of the unequalities and with the journey for more just new relations and emancipatórias of the Good to Live.
Por uma racionalidade ambiental: reflexões acerca dos regramentos propostos para pesca da tainha no estuário da Lagoa dos Patos/RS

As reflexões aqui expostas versam sobre a contribuição do Estado, apoiado no discurso científico, em regulações ambientais que têm como premissa uma visão dicotômica entre sociedade e ambiente. Ao não reconhecerem outras racionalidades na relação com o ambiente, as normativas nada mais são do que mecanismos promotores de conflitos ambientais. Nossa análise tem como suporte as normativas em vigor com vistas à gestão da tainha no sudeste e sul do Brasil, em especial, no estuário da Lagoa dos Patos/RS. Verificamos que as proposições se dão em uma perspectiva biologicista e estado-centrada que, ao mesmo tempo em que, inviabilizam a manutenção dos modos de vida dos pescadores(as) artesanais desta região, dão sustentação a uma pesca industrial destinada ao mercado externo.

For an environmental rationality: reflections about the proposed rules for fishing for mullet in the estuary of Lagoa dos Patos / RS

The reflections presented here discuss the contribution of the Statein

environmental regulations, supported by the scientific discourse predominantly of fisheries biology, that have as premise a dichotomous vision between society and environment. By not recognizing other rationalities in relation to the environment, the regulations are nothing more than mechanisms that promote environmental conflicts. Our analysis is based on current regulations for the management of mullet fisheries in the southeast and south of Brazil, especially in the estuary of Patos Lagoon/RS. We have verified that the propositions take place in a biologicist and state-centered perspective that, at the same time, make it impossible to maintain the livelihoods of the artisanal fishers of this region, and give support to an industrial fishing destined to the external market.

Key-words: artisanal fisheries, environmental conflicts, fisheries management, mullet, Patos Lagoon / RS.

Neste artigo apresentamos um estudo realizado para investigar a inserção da Educação Ambiental-EA na Base Nacional Comum Curricular-BNCC para a Educação Infantil e o Ensino Fundamental. Exibimos a análise documental realizada e as sínteses compreensivas acerca do que se mostra de referência à Educação Ambiental na BNCC. Compreendemos que diante dos movimentos de lutas e conquistas da EA, é lamentável a perda de espaço na BNCC, o que demostra mais um problema da BNCC. Assim, nos posicionamos contrárias à BNCC.

Adult growth hormone (GH) deficiency (AGHD) is a condition characterized by alterations in body composition, lipid and carbohydrate metabolism, bone mineral density and poor quality of life; however, clinical presentations of AGHD are mostly non-specific. Untreated AGHD is associated with increased cardiovascular morbidity and mortality. Stimulation tests are used for the diagnosis: insulin tolerance test, glucagon stimulation test, growth-hormone releasing hormone and arginine stimulation test. Moreover, in 2017 FDA approved the use of macimorelin (oral GH secretagogue) for the diagnosis of AGHD. In childhood GH-deficiency, apolipoprotein A-IV, CFHR4 (complement factor H-related protein 4) and PBP (platelet basic protein) were identified as potential biomarkers of the disease, however, this was not investigated in AGHD. GH treatment starts from the minimal dose, which allows minimizing the adverse effects. According to published meta-analyses, AGHD treatment generally does not lead to increased risk of malignancy and recurrence of sellar neoplasms in adult patients. Published data on GH receptor polymorphism associations with treatment efficacy remains controversial. Development of long-acting GH formulations is a currect perspective for the increase of treatment compliance.

Published: December 2019

En el marco del proceso de reintegración de desvinculados del conflicto armado en Colombia, y con base en el enfoque de desarrollo humano, la pregunta orientadora del presente ejercicio investigativo es: ¿qué relación existe entre las variables psicológicas y la expansión de capacidades que los desvinculados han tenido en su regreso a la vida civil? Tomando como base elementos del área psicológica, la hipótesis que se pretende demostrar es que el desarrollo positivo de variables psicológicas como el locus de control, los autoesquemas y las ideas irracionales, influyen en una reintegración exitosa y se manifiesta en la expansión de capacidades de desvinculados en proceso de reintegración. El resultado de la investigación sugiere que las personas en cuyo proceso de reintegración se observó una mayor expansión de capacidades presentan un locus de control ajustado, junto a un mayor desarrollo de la autoestima y menor incidencia de algunas ideas irracionales.

Published: December 2019

La firma de los Acuerdos de Paz en Colombia ha posicionado en el debate público, académico y social la noción de reconciliación. Sin embargo, no existe una definición o comprensión unívoca del término; el contenido de reconciliación es determinado por las concepciones que se tenga sobre el conflicto, sus dinámicas y la paz. El presente trabajo aborda cuál debe ser la noción de reconciliación que requiere Colombia para transitar hacia escenarios de paz, sugiere que la reconciliación democrática, política y sustentada en nociones de reconocimiento es la ideal para construir una paz estable y duradera.
Una nueva dimensión para el análisis de la ciudadanía: empoderamiento político a través del proceso de construcción de paz en Samaniego, Colombia
Authors: Tobar Manzo Juan Manuel
Published: December 2019

Los procesos de construcción de paz en escenarios de conflicto armado, como en Samaniego, Nariño, dan cuenta de los diversos alcances y múltiples dimensiones que pueden ser considerados para analizar la ciudadanía. Teniendo en cuenta las capacidades políticas adquiridas por los actores locales durante el proceso de construcción de paz entre el 2009 y 2014, se analiza la capacidad y legitimidad de hacer del proceso de construcción de paz un elemento relevante para analizar la ciudadanía. Se hace uso del estudio de caso como método de investigación, las entrevistas semiestructuradas, la observación in situ y el análisis documental como herramientas de recabo de información; se articula una metodología capaz de entender las diferentes expresiones de resistencia civil del contexto y cómo estas coadyuvan al proceso de transformación de la ciudadanía.

Published: December 2019

This paper presents the results of pea straw compaction efficiency tests. The compliance of the tested material to pressure agglomeration was assessed depending on the compaction pressure used (45-113 MPa). The compaction was carried out using a Zwick testing machine, type Z020/TN2S, and a closed die pressing unit. It was found that, along with the pressure increase, the material density in the chamber increased (from 1.255 to 1.76 g∙cm−3), as well as the agglomerate's density (from 0.739 to 1.05 g∙cm−3) and the product's mechanical resistance (from 0.31 to 0.69 MPa). Increasing the compaction pressure in the analyzed range increased the unit value of compaction work, from 17.16 to 34.27 J·g−1.
