Conservación crítica: re-imaginando el "objeto" de conservación contemporáneo
Authors: Escobar Castrillón Natalia 
Published: March 2019

Este ensayo revisa las teorías de la historia sobre las que la definición del objeto de conservación arquitectónico moderno se ha fundamentado y que la práctica normativa continúa perpetuando en la actualidad. En su lugar propone la teoría de la historia del crítico literario Walter Benjamin, así como la teoría del juicio estético del filósofo Immanuel Kant como posibles vías para re-imaginar el objeto de conservación contemporáneo y renovar la disciplina. Ambas teorías asignan a la imaginación un rol mediador fundamental en la construcción de la realidad, y entienden dicha construcción como resultado de un proceso dialéctico entre la experiencia vivida y su conceptualización. La mediación de la imaginación en la construcción del objeto de conservación contemporáneo implica un alejamiento de teorías que presumen estatus científico en la recuperación del pasado. En su lugar, la naturaleza alegórica y dialéctica de nuestro entendimiento del pasado desde el presente demanda participación, responsabilidad y compromiso de la sociedad en el proceso. Se denomina conservación crítica, por tanto, al conjunto de decisiones que se toman desde la conciencia del proyecto de conservación arquitectónica como una construcción ideológica.

Autonomous Soil Water Content Sensors Based on Bipolar Transistors Encapsulated in Porous Ceramic Blocks

Published: March 2019

We present an autonomous sensor to measure soil water content that uses a single heat pulse probe based on a transistor encapsulated in a porous block. The sensor uses a bipolar junction transistor, which performs as both a heating and temperature-sensing element. Since the sensor depends on a porous block to measure the matric potential of the soil, it does not suffer from accuracy problems if the contact between the probe and the soil is not perfect. A prototype of the sensor showed a temperature variation of Δ T = 2.9 ∘ C when the porous ceramic was saturated with water. The sensor presented an almost linear behavior for small changes in the matric potential of a red latosol when tested in the 1-kPa and 35-kPa pressure range, showing a sensitivity of S = 0.015 ∘ C/kPa. The ultra-low power signal conditioning circuit can read the sensor’s temperature with a resolution of approximately 0.02 ∘ C, so the matric potential can be read in increments of at least 1.33 kPa. When powered only by a 2-F supercapacitor from the energy-harvesting system, the interrogation circuit is able to take one soil water content measurement per day, for eleven days.
The Axial Rotation and Variable Macroturbulence of RR Lyrae and Red Horizontal Branch Stars

Published: March 2019

Abstract
We have derived relations between FWHMs and equivalent widths of metallic absorption lines in the spectra of RR Lyrae stars to estimate new upper limits on the axial equatorial rotational velocities of RR Lyrae and metal-poor red horizontal branch (RHB) stars. We have also derived the variations of RR Lyrae macroturbulent velocities during the pulsation cycles. In RRab cycles, the line widths are dominated by phase-dependent convolutions of axial rotation and macroturbulence, which we designate as V
macrot. The behavior of V
macrot is remarkably uniform among the RRab stars, but the behavior of V
macrot among RRc stars varies strongly from star to star. The RRab stars exhibit an upper limit on V
macrot of 5 ± 1 km s−1 with weak evidence of an anticorrelation with T
eff. The RRc minima range from 2 to 12 km s−1. The abrupt decline in large rotations with decreasing T
eff at the blue boundary of the instability strip and the apparently smooth continuous variation among the RRab and RHB stars suggests that HB stars gain/lose surface angular momentum on timescales that are short compared to HB lifetimes. The V
macrot values for our metal-poor RHB stars agree well with those derived by Fourier analysis of an independent but less metal-poor sample of Carney et al.; they conform qualitatively to the expectations of Tanner et al. A general conclusion of our investigation is that surface angular momentum as measured by V
rot sin (i) is not a reliable indicator of total stellar angular momentum anywhere along the HB.

Abstract
We present integrated pulse profiles at 5 GHz for 71 pulsars, including eight millisecond pulsars (MSPs), obtained using the Shanghai Tian Ma Radio Telescope. Mean flux densities and pulse widths are measured. For 19 normal pulsars and one MSP, these are the first detections at 5 GHz—and for a further 19, including five MPSs, the profiles have a better signal-to-noise ratio than previous observations. Mean flux density spectra between 400 MHz and 9 GHz are presented for 27 pulsars and correlations of power-law spectral index are found with characteristic age, radio pseudo-luminosity, and spin-down luminosity. Mode changing was detected in five pulsars. The separation between the main pulse and interpulse is shown to be frequency independent for six pulsars, but a frequency dependence of the relative intensity of the main pulse and interpulse is found. The frequency dependence of component separations is investigated for 20 pulsars, and three groups are found: in seven cases, the separation between the outmost leading and trailing components decreases with frequency, roughly in agreement with radius-to-frequency mapping; in 11 cases, the separation is nearly constant; in the remaining two cases, the separation between the outmost components increases with frequency. We obtain the correlations of pulse widths with pulsar period and estimate the core widths of 23 multicomponent profiles and conal widths of 17 multicomponent profiles at 5.0 GHz using Gaussian fitting, and we discuss the width-period relationship at 5 GHz compared with the results at at 1.0 and 8.6 GHz.
Stromal Interaction Molecule Deficiency in T Cells Promotes Spontaneous Follicular Helper T Cell Development and Causes Type 2 Immune Disorders
Authors: Oh-hora Masatsugu , Lu Xiuyuan , Shiokawa Moe , Takayanagi Hiroshi , Yamasaki Sho 
Published: March 2019

Abstract
Appropriate T cell responses are controlled by strict balance between activatory and inhibitory pathways downstream of TCR. Although mice or humans with impaired TCR signaling develop autoimmunity, the precise molecular mechanisms linking reduced TCR signaling to autoimmunity are not fully understood. Engagement of TCR activates Ca2+ signaling mainly through store-operated Ca2+ entry activated by stromal interaction molecule (Stim) 1 and Stim2. Despite defective T cell activation, mice deficient in both Stim1 and Stim2 in T cells (conditional double knockout [cDKO]) developed lymphoproliferative disorders and skin inflammation with a concomitant increase in serum IgG1 and IgE levels. In cDKO mice, follicular helper T (Tfh) cells were dramatically increased in number, and they produced IL-4 spontaneously. These inflammatory symptoms were abolished by the deletion of IL-4 in cDKO mice. Tfh development and inflammatory symptoms in cDKO mice were abrogated by further deletion of NFAT2 in T cells. These findings suggest that Tfh cells spontaneously developed in the absence of Ca2+ signaling and caused unregulated type 2 responses.

Authors: Cunha Ricardo Borges da , Rückert Aldomar Arnoldo 
Published: March 2019

A formação do Polo Naval Offshore de Rio Grande envolve um conjunto de processos, políticos econômicos e sociais. A elaboração de programas de expansão da frota de apoio às operações da Petrobras foi fundamental para o lançamento das políticas nacionais para o setor naval. Entretanto foi a descoberta do pré-sal que a indústria naval expandiu para diferentes regiões do país, como nos município de Rio Grande e São José do Norte. A instalação de 4 estaleiros, destinados a construção e manutenção de plataformas de petróleo e navios de apoio naval, impactaram em todo estado do Rio Grande do Sul. A construção do maior dique-seco da América-latina consolidou a região no cenário nacional de produção naval. Entretanto alterações nas políticas do setor decretou a falência da construção naval na região, gerando a imediata redação na mão de obra e abandono das estruturas construídas.
Quality of life of patients with chronic obstructive pulmonary disease treated with indacaterol
and/or glycopyrronium: a real-world Polish observational study
Authors: Płusa Tadeusz 
Published: March 2019

IntroductionThe aim of this study was to evaluate the impact of routinely administered treatment with indacaterol and/or glycopyrronium on quality of life and level of dyspnoea of patients with chronic obstructive pulmonary disease (COPD) in a real-life setting.Material and methodsIt was an observational, non-interventional study in patients with stable, symptomatic chronic obstructive pulmonary disease initiating treatment with indacaterol and/or glycopyrronium as part of routine care. The primary outcomes included a change in quality of life measured using the Clinical COPD Questionnaire (CCQ) and level of dyspnoea evaluated using the modified Medical Research Council scale (mMRC). Patients were followed up for 6 months after initiation of treatment.ResultsAnalysis included baseline data from 586 patients. At 6 months 82.5% (n = 483) of patients were continuing initiated treatment. Improvement of mMRC and CCQ scores was observed in all treatment arms. The mean total CCQ score ± SD changed after 6 months from 2.2 ±0.9 to 1.2 ±0.9 in the indacaterol group (p < 0.001), from 2.1 ±1.0 to 1.0 ±0.9 (p < 0.001) in the glycopyrronium group and 2.6 ±1.1 at baseline to 1.3 ±1.0 (p < 0.001) in the indacaterol/glycopyrronium group. The mean mMRC ± SD decreased from 2.1 ±0.9 to 1.4 ±0.9 (p < 0.001) in the indacaterol group, from 2.1 ±0.9 to 1.2 ±1.0 (p < 0.001) in the glycopyrronium group, and from 2.3 ±0.8 to 1.4 ±0.9 (p < 0.001) in the indacaterol/glycopyrronium group.ConclusionsUse of indacaterol and/or glycopyrronium improved quality of life and breathlessness in patients with stable COPD, efficiently reducing the symptoms burden.

Abstract. Albumen
quality is a leading economic trait in the chicken industry. Major studies have paid
attention to genetic architecture underlying albumen quality. However, the putative
quantitative trait locus (QTL) for this trait is still unclear. In this genome-wide
association study, we used an F2 resource population to study longitudinal albumen
quality. Seven single-nucleotide polymorphism (SNP) loci were found to be significantly
(p<8.43×10-7) related to albumen quality by univariate analysis,
while 11 SNPs were significantly (p<8.43×10-7) associated with
albumen quality by multivariate analysis. A QTL on GGA4 had a pervasive function on
albumen quality, including a SNP at the missense of NCAPG, and a SNP at the
intergenic region of FGFPB1. It was further found that the putative QTLs at
GGA1, GGA2, and GGA7 had the strongest effects on albumen height (AH) at 32 weeks, Haugh
units (HU) at 44 weeks, and AH at 55 weeks. Moreover, novel SNPs on GGA5 and GGA3 were
associated with AH and HU at 32, 44, and 48 weeks of age. These results confirmed the
regions for egg weight that were detected in a previous study and were similar with QTL
for albumen quality. These results showed that GGA4 had the strongest effect on albumen
quality. Only a few significant loci were detected for most characteristics probably
reflecting the attributes of a pleiotropic gene and a minor-polygene in quantitative
traits.
Links of climate variability in Arctic sea ice, Eurasian teleconnection pattern and summer surface ozone pollution in North China
Authors: Yin Zhicong , Wang Huijun , Li Yuyan , Ma Xiaohui , Zhang Xinyu 
Published: March 2019

Abstract. Summer surface O3 pollution has rapidly
intensified in China in the recent decade, damaging human and ecosystem
health. In 2017, the summer mean maximum daily average 8 h concentration of
ozone was greater than 150 µg m−3 in North
China. Based on the close relationships between the O3
concentration and the meteorological conditions, a daily surface O3
weather index was constructed, which extends the study period to the
historical period before 2007 and the projected future. Here, we show that in
addition to anthropogenic emissions, the Eurasian teleconnection
pattern (EU), a major globally atmospheric teleconnection pattern, influences
surface O3 pollution in North China on a timescale of climate. The
local meteorological conditions associated with the EU positive phase
supported intense and efficient photochemical reactions to produce more
surface O3. The associated southerlies over North China transported
surrounding O3 precursors to superpose local emissions. Increased
solar radiation and high temperatures during the positive EU phase
dramatically enhanced O3 production. Furthermore, due to the close
connection between the preceding May Arctic sea ice (SI) and summer EU
pattern, approximately 60 % of the interannual variability in
O3-related weather conditions was attributed to Arctic sea ice to
the north of Eurasia. This finding will aid in understanding the interannual
variation in O3 pollution, specifically the related meteorological
conditions.

Authors: Shandra John M , Restivo Michael , Sommer Jamie M 
Published: March 2019

The theory and empirical research on ecologically unequal exchange serves as the starting point for this study. We expand the research frontier it in a novel way by applying the theory to China and empirically testing if forestry export flows from low-and middle-income nations to China are related to increased forest loss in the exporting nations. In doing so, we analyze data for 75 low-and middle-income nations using ordinary least squares regression and find support for our main hypothesis.
Fintech Adoption Choices of Small Businesses: A Technology Organization Environment (TOE) Framework study
Authors: Varma Ashish 
Published: March 2019

Financial technology or “FinTech” is an amalgam of the use of technology for financial transactions and processes. Fintech adoption for business processes by small businesses largely remains unexplored in the context of emerging markets. This study was conducted during late 2018 using a sample of 117 owner and managers of small businesses in India, for exploring the fintech adoption through the Technology Organization Environment (TOE) framework. The method applied for data analysis was partial least squares structural equation modeling (PLS-SEM). It was found that perceived direct benefits of fintech had a significant effect on fintech adoption. Counter-intuitively, the perceived cost of fintech adoption was not a significant factor in fintech adoption. These results have significant managerial and academic relevance for understanding fintech adoption agenda of small businesses in the emerging markets.
Dual effects of biochar and hyperaccumulator Solanum nigrum L. on the remediation of Cd-contaminated soil

Published: March 2019

Biochar was widely developed for the soil amendment and remediation of heavy metal contaminated soil. The Cd hyperaccumulator, Solanum nigrum L., has been paid much more attention with the wide application of phytoremediation. The effects of biochar on the growth and accumulation capacity of Solanum nigrum L. in Cd contaminated soil have not been explored so far. The objectives of this study were to explore the dual effects of biochar addition on available Cd in the soil and hyperaccumulation of Cd in Solanum nigrum L. under different Cd contaminated levels. The correlations of soil physicochemical and biochemical properties and Cd absorption of Solanum nigrum L. were analyzed after a 60-day pot experiment under three biochar doses (0%, 1% and 5%) and four Cd concentrations (0, 25, 50 and 100 mg kg−1). The availability of Cd obtained by DTPA extraction significantly decreased after biochar application (P = 0.003, P = 0.0001, P = 0.0001 under 1% biochar addition for 25, 50, and 100 mg kg−1 Cd concentrations, P = 0.0001, P = 0.0001, P = 0.0001 under 5% biochar addition for 25, 50, and 100 mg kg−1 Cd concentrations, n ≥ 3). The 1% biochar dose significantly increased leaf dry weight (P = 0.039, P = 0.002 for the Cd concentrations of 50 and 100 mg kg−1, n ≥ 3) compared with the control in higher Cd concentrations (50 and 100 100 mg kg−1). In the presence of biochar, the bioconcentration factor (BCF) increased under the Cd concentrations of 50 and 100 mg kg−1. The translocation factors (TF) decreased with the biochar doses under the Cd concentration of 100 mg kg−1. The dose of 5% biochar significantly increased the urease activity by 41.18% compared to the 1% biochar addition in the Cd contaminated soil of 50 mg kg−1 concentration. The activities of acid phosphatase were inhibited by 1% biochar dose in all the Cd contaminated soils. The dry weight of the root of Solanum nigrum L. was significantly negatively correlated with acid phosphatase activity and BCF, respectively, indicating acid phosphatase in the rhizosphere soil of Solanum nigrum L. were repressed by Cd toxicity despite of biochar amendment. Biochar had no negative effect on Cd accumulation ability of Solanum nigrum L. Two-way ANOVA analysis showed that both biochar and Cd significantly affected the height of Solanum nigrum L. and the dry weight of leaf and stem. This study implied that biochar addition does not limit the absorption of hyperaccumulator Solanum nigrum L. in the remediation of Cd-contaminated soil. This study implied that the simultaneous application of biochar and hyperccumulator Solanum nigrum L. is promising during the remediation of Cd-contaminated soil.
A meta‐analysis of the relationship between moral disengagement and bullying roles in youth
Authors: Killer Brittany , Bussey Kay , Hawes David J , Hunt Caroline 
Published: March 2019

AbstractOver the last several years, researchers have become increasingly interested in the influence of moral factors on bullying behaviors. This is the first meta‐analytic review to exclusively examine the relationship between moral disengagement (MD) and the key bullying roles of bully, victim, defender, and bystander. Forty‐seven independent samples examining a total of 43,809 children/adolescents (aged 7–19) were included in this meta‐analysis. Results indicated a positive relationship between MD and bullying (r = 0.31; 95% CI [0.27, 0.34]), MD and victimization (r = 0.08; 95% CI [0.05, 0.12]), and a negative relationship between MD and defending (r = −0.11; 95% CI [−0.17, −0.04]). No significant relationship was found for MD and bystanding behavior. Moderators of bullying type (traditional vs. cyberbullying), reporting type (self vs. peer report), age, and gender were included in the analyses. The results are discussed in the context of relevant literature with particular emphasis on the importance of distinguishing between guilty and unconcerned bystanders, and the significant overlap between bullying and victimization in the cyber context.
Relating brain connectivity with persistent symptoms in pediatric concussion

Published: March 2019

AbstractPersistent post‐concussion symptoms (PCS) in children following a mild traumatic brain injury (mTBI) are a growing public health concern. There is a pressing need to understand the neural underpinning of PCS. Here, we examined whole‐brain functional connectivity from resting‐state fMRI with behavioral assessments in a cohort of 110 children with mTBI. Children with mTBI and controls had similar levels of connectivity. PCS symptoms and behaviors including poor cognition and sleep were associated with connectivity within functional brain networks. The identification of a single “positive‐negative” dimension linking connectivity with behaviors enables better prognosis and stratification toward personalized therapeutic interventions.
