Abstract. In the present study, the WRF-Chem model is used to assess
contributions of residential coal combustion (RCC) emissions to the air
quality in Beijing–Tianjin–Hebei (BTH) during a persistent air pollution
episode from 9 to 25 January 2014. In general, the predicted temporal
variations and spatial distributions of the mass concentrations of air
pollutants are in good agreement with observations at monitoring sites in
BTH. The WRF-Chem model also reasonably reproduces the temporal variations
in aerosol species when compared with the aerosol mass spectrometer measurements in Beijing. The
RCC emissions play an important role in the haze formation in BTH,
contributing about 23.1 % of PM2.5 (fine particulate matter) and
42.6 % of SO2 during the simulation period on average. Organic
aerosols dominate the PM2.5 from the RCC emissions in BTH, with a
contribution of 42.8 %, followed by sulfate (17.1 %). The air quality in
Beijing is remarkably improved when the RCC emissions in BTH and the
surrounding areas are excluded in model simulations, with a 30 % decrease
in PM2.5 mass concentrations. However, if only the RCC emissions in
Beijing are excluded, the local PM2.5 mass concentration is decreased by
18.0 % on average. Our results suggest that the implementation of the
residential coal replacement by clean energy sources in Beijing is
beneficial to the local air quality. Should residential coal replacement
be carried out in BTH and its surrounding areas, the air quality in Beijing
would be improved remarkably. Further studies would need to consider
uncertainties in the emission inventory and meteorological fields.
Patterns of longer-term climate change effects on CO2 efflux from biocrusted soils differ from those observed in the short term

Published: July 2018

Abstract. Biological soil crusts (biocrusts) are predicted to be
sensitive to the increased temperature and altered precipitation associated
with climate change. We assessed the effects of these factors on soil carbon
dioxide (CO2) balance in biocrusted soils using a sequence of
manipulations over a 9-year period. We warmed biocrusted soils by 2 and,
later, by 4 ∘C to better capture updated forecasts of future
temperature at a site on the Colorado Plateau, USA. We also watered soils to
alter monsoon-season precipitation amount and frequency and had plots that
received both warming and altered precipitation treatments. Within treatment
plots, we used 20 automated flux chambers to monitor net soil exchange (NSE)
of CO2 hourly, first in 2006–2007 and then again in 2013–2014, for a
total of 39 months. Net CO2 efflux from biocrusted soils in the warming
treatment increased a year after the experiment began (2006–2007). However,
after 9 years and even greater warming (4 ∘C), results were more
mixed, with a reversal of the increase in 2013 (i.e., controls showed higher
net CO2 efflux than treatment plots) and with similarly high rates in
all treatments during 2014, a wet year. Over the longer term, we saw
evidence of reduced photosynthetic capacity of the biocrusts in response to
both the temperature and altered precipitation treatments. Patterns in
biocrusted soil CO2 exchange under experimentally altered climate
suggest that (1) warming stimulation of CO2 efflux was diminished later
in the experiment, even in the face of greater warming; and (2) treatment
effects on CO2 flux patterns were likely driven by changes in biocrust
species composition and by changes in root respiration due to vascular plant
responses.

Published: July 2018

Abstract. Over the past 20 years satellite remote sensing has captured significant
downwasting of glaciers that drain the West Antarctic Ice Sheet into the
ocean, particularly across the Amundsen Sea Sector. Along the neighbouring
Marie Byrd Land Sector, situated west of Thwaites Glacier to Ross Ice Shelf,
glaciological change has been only sparsely monitored. Here, we use optical
satellite imagery to track grounding-line migration along the Marie Byrd Land
Sector between 2003 and 2015, and compare observed changes with ICESat and
CryoSat-2-derived surface elevation and thickness change records. During the
observational period, 33 % of the grounding line underwent retreat, with
no significant advance recorded over the remainder of the ∼ 2200 km
long coastline. The greatest retreat rates were observed along the
650 km-long Getz Ice Shelf, further west of which only minor retreat
occurred. The relative glaciological stability west of
Getz Ice Shelf can be
attributed to a divergence of the Antarctic Circumpolar Current from the
continental-shelf break at 135∘ W, coincident with a transition in
the morphology of the continental shelf. Along Getz Ice Shelf, grounding-line
retreat reduced by 68 % during the CryoSat-2 era relative to earlier
observations. Climate reanalysis data imply that wind-driven upwelling of
Circumpolar Deep Water would have been reduced during this later period,
suggesting that the observed slowdown was a response to reduced oceanic
forcing. However, lack of comprehensive oceanographic and bathymetric
information proximal to Getz Ice Shelf's grounding zone make it difficult to
assess the role of intrinsic glacier dynamics, or more complex
ice-sheet–ocean interactions, in moderating this slowdown. Collectively, our
findings underscore the importance of spatial and inter-decadal variability
in atmosphere and ocean interactions in moderating glaciological change
around Antarctica.
Pore morphology of polar firn around closure revealed by X-ray tomography

Published: July 2018

Abstract. Understanding the slow densification process of polar firn into ice is
essential in order to constrain the age difference between the ice matrix and
entrapped gases. The progressive microstructure evolution of the firn column
with depth leads to pore closure and gas entrapment. Air transport models in
the firn usually include a closed porosity profile based on available data.
Pycnometry or melting–refreezing techniques have been used to obtain the
ratio of closed to total porosity and air content in closed pores,
respectively. X-ray-computed tomography is complementary to these methods, as
it enables one to obtain the full pore network in 3-D. This study takes
advantage of this nondestructive technique to discuss the morphological
evolution of pores on four different Antarctic sites. The computation of
refined geometrical parameters for the very cold polar sites Dome C and
Lock In (the two Antarctic plateau sites studied here) provides new
information that could be used in further studies. The comparison of these
two sites shows a more tortuous pore network at Lock In than at Dome C, which
should result in older gas ages in deep firn at Lock In. A comprehensive
estimation of the different errors related to X-ray tomography and to the
sample variability has been performed. The procedure described here may be
used as a guideline for further experimental characterization of firn
samples. We show that the closed-to-total porosity ratio, which is
classically used for the detection of pore closure, is strongly affected by
the sample size, the image reconstruction, and spatial heterogeneities. In
this work, we introduce an alternative parameter, the connectivity index,
which is practically independent of sample size and image acquisition
conditions, and that accurately predicts the close-off depth and density. Its
strength also lies in its simple computation, without any assumption of the
pore status (open or close). The close-off prediction is obtained for Dome C
and Lock In, without any further numerical simulations on
images (e.g., by permeability or
diffusivity calculations).
costoso engaño del cambio climático y el calentamiento global
Authors: Badía Serra Eduardo 
Published: July 2018

El presente escrito plantea el costo de afrontar medidas tendientes a disminuir las consecuencias del cambio climático de que hablan los países de cuantioso poder económico. Partiendo de las posturas antropocentristas que hicieron de la naturaleza un objeto de abuso, el autor recorre las propuestas del pensamiento antrópico, Penrose y las ideas homocentristas, para decantar en la historia de la tierra y en el cambio climático. Poniendo al descubierto la falsedad de los numerosos anuncios catastróficos de los ‘grupos de científicos’, propone ocuparse de los verdaderos problemas, como la degradación ambiental y la vulnerabilidad ante la naturaleza de la sociedad humana.
Resources and Capabilities from Their Very Outset: a Bibliometric Comparison Between Scopus and the Web of Science
Authors: Alvarez-Melgarejo Mileidy , Torres-Barreto Martha L. 
Published: July 2018

The bibliometric method has proven to be a powerful tool for the analysis of scientific publications, in such a way that allows rating the quality of the knowledge generating process, as well as its impact on firm´s environment. This article presents a comparison between two powerful bibliographic databases in terms of their coverage and the usefulness of their content. The comparison starts with a subject associated to the relationship between resources and capabilities. The outcomes show that the search results differ between both databases. The Web Of Science (WOS), has a greater coverage than SCOPUS has. It also has a greater impact in terms of most cited authors and publications. The search results in the WOS yield articles from 2001, while Scopus yields articles from 1976, however, some of the latter are inconsistent with the topic being searched. The analysis points to a lack of studies regarding resources as foundations of firm´s capabilities; as a result, new research on this field is suggested.

Incorporation Doctrine’s Federalism Costs: A Cautionary Note for the European Union
In this article, I first briefly describe the U.S. Supreme Court’s decades-long process of incorporating the federal Bill of Rights against the states. Second, I argue that incorporation of the Bill of Rights has come with significant costs to federalism in the United States. Third, I suggest that the American experience provides a cautionary note for the European Union as it grapples with the question of whether and to what extent to apply the Charter of Fundamental Rights to its constituent nations. I end by identifying options available to the European Union to avoid at least some of this harm to federalism while, at the same time, securing some of the benefit that might be occasioned by incorporating the Charter.

Ethical Aspects in Web Marketing for Seniors: A Grid for Linguistic Analysis
Authors: Kim Grego  
Published: July 2018

People aged 65 and over make up an increasing share of the population of both the US and Europe as well as of other developed countries. Similarly to the elderly from the past, as social actors they are prone to vulnerability and risk due to their age. However, today’s seniors are different from seniors from past decades as regards education, finances and IT skills, as well as in their motivations, expectations and needs. They also increasingly negotiate their own age discursively, making it no longer a factual datum but a flexible one. This makes it difficult for public and private institutions alike to understand them as consumers. Drawing from previous research in sociolinguistics, marketing and social studies, this study aims to propose a grid for the linguistic analysis of the opportunities and risks inherent in (web-)marketing texts aimed at seniors, with particular attention to the ethical repercussions that these may have for them. The potential strengths and possible limits of the proposed grid are then evaluated, and suggestions for future developments are put forward.
“The diet is not suitable for all...”: On the British and Irish web-based discourse on the Ketogenic Diet
Authors: Davide Mazzi  
Published: July 2018

This paper is aimed at analysing the discourse tools and argumentative resources at work in the debate on the Ketogenic Diet (KD), an increasingly popular regimen with far-reaching clinical implications. The study centred on two small comparable corpora including web-based materials from relevant stakeholders in the debate on the KD, namely health institutions, charities and the press from the UK and Ireland. From a methodological point of view, the study consisted of two main stages: first of all, a quantitative analysis of phraseology focusing on lexical bundles; secondly, a qualitative study of patterns of argumentative discourse, for the purpose of identifying common argument schemes and their relationship in the overall argument structure. On the one hand, the British discourse on the KD broadly reflects the deeply-held conviction that the diet should be given proper consideration, especially in the treatment of drug-resistant epilepsy. On the other hand, the Irish discourse on the diet appears to be more complex and multilayered. The role of the KD as a significant component of epilepsy treatment is acknowledged, but at the same time citations from influential figures often fulfil different argumentative commitments.
Stem Cells and (Pseudo)Science: Discursive Aspects of the Stamina Case as Seen in Nature
Authors: Alessandra Vicentini  
Published: July 2018

This study examines the Stamina case, one of the most controversial mediatic incidents of the last years in Italy, from an applied linguistic perspective. Through the analysis of a small corpus of texts published on the online version of Nature (Nature.com) between 2013 and 2014, it investigates how scientists, political and health institutions, the media, the patients and the public interact when faced with (pseudo)scientific news that may be relevant from a public health perspective. Based on selected sociological models of science communication (Bucchi 1998; Bucchi and Neresini 2008; Trench 2008; Hetland 2014; Metcalfe 2014; Neresini 2015), combined with methodological tools from critical discourse analysis (Fairclough 1995, 2003; Eisenhart and Johnstone 2008; Wodak 2013), argumentation theory (van Eemeren et al. 2004), and making reference to science popularisation studies (Calsamiglia 2003; Garzone 2006), the qualitative analysis shows how the communication pattern of scientific news with public health relevance is changing. Power relations are on the move and so are the aims, the communicative strategies and the genres employed. These are in fact influenced by a growing interaction between bottom-up pressures (patients, families, the public, the media) and a topdown diffusion of information (scientists, political and healthcare institutions, the media) with the latter prevailing over the former. From the data collected, it seems crucial that the dissemination and popularisation of scientific issues should be further spread. Scientists must counter propaganda and hysteria on (social) media, as well as engage more directly with people (Hunter 2016) in order to oppose pseudoscience.

AbstractCurrently, the available literature provides insufficient support to differentiate between primary ovarian neuroendocrine tumors (PON) and neuroendocrine ovarian metastases (NOM) in patients. For this reason, patients with a well‐differentiated ovarian neuroendocrine tumor (NET) were identified through electronic patient records and a nationwide search between 1991 and 2023. Clinical characteristics were collected from electronic patient files. This resulted in the inclusion of 71 patients with NOM and 17 patients with PON. Histologic material was stained for Ki67, SSTR2a, CDX2, PAX8, TTF1, SATB2, ISLET1, OTP, PDX1, and ARX. DNA methylation analysis was performed on a subset of cases. All PON were unilateral and nine were found within a teratoma (PON‐T+). A total of 78% of NOM were bilateral, and none were associated with a teratoma. PON without teratomous components (PON‐T−) displayed a similar insular growth pattern and immunohistochemistry as NOM (p > 0.05). When compared with PON‐T+, PON‐T− more frequently displayed ISLET1 positivity and were larger, and patients were older at diagnosis (p < 0.05). Unsupervised analysis of DNA methylation profiles from tumors of ovarian (n = 16), pancreatic (n = 22), ileal (n = 10), and rectal (n = 7) origin revealed that four of five PON‐T− clustered together with NOM and ileal NET, whereas four of five PON‐T+ grouped with rectum NET. In conclusion, unilateral ovarian NET within a teratoma should be treated as a PON. Ovarian NET localizations without teratomous components have a molecular profile analogous to midgut NET metastases. For these patients, a thorough review of imaging should be performed to identify a possible undetected midgut NET and a corresponding follow‐up strategy may be recommended.

Published: November 2024

AbstractOrganic cathodes are considered promising energy storage materials in potassium ion batteries (KIBs) due to their molecular flexibility, cost‐effectiveness, and sustainability. However, challenges such as high solubility and slow reaction kinetics hinder the development of organic molecules for KIBs. Herein, a novel in situ self‐assembly strategy is presented to construct a robust hydrogen‐bonded organic framework cathode (H‐NDA‐G) with extensive π‐conjugated systems and excellent chemical stability. By selecting 2,4‐diaminotriazine as the connecting ligand, which serves both as a hydrogen bond donor and acceptor, the H‐NDA‐G cathode is constructed utilizing its amide reaction with dianhydride and the strong π–π adsorption interactions with graphene oxide (GO). The weak electronic coupling between H‐NDA‐G not only provides charge transfer channels within the framework but also forms an interconnected conductive network through hydrogen bonding and π–π adsorption with the GO, facilitating the redox reactions of K+ within the H‐NDA‐G electrode. Consequently, the H‐NDA‐G cathode exhibits extraordinary performance with a high capacity (120 mAh g−1 at 0.1 A g−1) and cycle life exceeding 1000 cycles at 1 A g−1, demonstrating significant potential for practical applications. This study underscores the potential to enhance the potassium storage capability of organic cathodes by modulating intermolecular forces toward efficient and sustainable KIBs.
Cation‐Alginate Complexes and Their Hydrogels: A Powerful Toolkit for the Development of Next‐Generation Sustainable Functional Materials
Authors: Tordi Pietro , Ridi Francesca , Samorì Paolo , Bonini Massimo 
Published: November 2024

AbstractThe use of materials from renewable sources instead of fossil fuels is a crucial step forward in the industrial transition toward sustainability. Among polysaccharides, alginate stands out as a versatile and eco‐friendly candidate due to its ability to form functional complexes with cations. This review provides an up‐to‐date and comprehensive description of alginate complexation with specific cations, focusing on how interaction forces can be harnessed to tailor the physicochemical properties of cation‐alginate‐based functional materials. Methodologies and approaches for the development and multiscale characterization of these materials are introduced and discussed. Alginate complexes with mono‐, di‐, tri‐, and tetravalent cations (namely Ag+, Mg2+, Ca2+, Sr2+, Ba2+, Mn2+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Pb2+, UO22+, Cr3+, Fe3+, Al3+, Ga3+, Y3+, La3+, Ce3+, Nd3+, Eu3+, Tb3+, Gd3+, Zr4+, Th4+) are reviewed. Each cation is discussed individually, highlighting how it can uniquely influence the material properties thereby unlocking new potentials for the design of advanced functional materials. Key challenges and opportunities in applying these complexes across diverse fields, such as biomedicine, environmental remediation, food additives and supplements, flame retardants, sensors, supercapacitors, catalysis, and mechanical isolators are assessed, providing evidence of the transformative potential of cation‐alginate complexes for tackling global challenges and advancing cutting‐edge technologies.
A novel piglet model of esophageal stricture following variable segmental esophageal resection and re‐anastomosis

Published: November 2024

AbstractBackgroundEsophageal strictures following esophageal atresia repair are a source of significant morbidity. To test new therapeutic approaches, we designed a piglet model of esophageal stricture by resecting variable lengths of esophagus with subsequent re‐anastomosis. This study describes the model and validates its physiologic impact by blinded analysis of the weight gains of the piglets.MethodsA total of 24 two‐week old Pietrain piglets had esophageal resections performed, ranging from 0 to 5 cm, with the goal of inducing postoperative esophageal strictures. Postoperative body‐weights were evaluated by repeated analysis of variance followed by pairwise group‐comparisons based on estimated marginal means. In addition, body weight was modeled by linear‐mixed model regression. Different resection lengths were compared. The esophagi were evaluated postmortem for stricture.ResultsOf 24 operated piglets, 23 reached the endpoint, and 90% developed an esophageal stricture that was radiologically visible in a contrast study, as well as appreciable macroscopically in the necropsy. We found differences in pre‐ and postoperative body weights for all piglets (F (1, 18) = 298.54, p < 0.001), but no differences between resection lengths (F (4, 18) = 0.36, p = 0.837).ConclusionOur model of postoperative esophageal stricture offers the opportunity to investigate potential treatments for strictures associated with esophageal atresia, since it reliably induces strictures and results in minimal loss of animals. The similar body weight gain in all groups indicates that stricture is mainly the result of esophageal resection and re‐anastomosis, regardless of the length of the resected segment.
