Ceramics and Globalization
Authors: Ewins Neil
Published: October 2018

Neil Ewins’ study of the Staffordshire potteries in a period of great global change traces how ceramics production has been affected by globalisation in both familiar and unexpected ways.

Although many manufacturers such as Wedgwood initially moved production to cheaper labour markets in East Asia, others remained in or returned to England once it became clear that outsourcing manufacturing was affecting the brand value and customer perception of their products. Neil Ewins explores the complex behaviour of the UK ceramics industry, using a combination of evidence from the press, trade journals, ceramic objects, and primary interview evidence of manufacturers, retailers and a ceramic designer.

Ewins suggests that, although the surface designs of UK ceramics invariably reflect diverse cultural and stylistic influences, a notion of authenticity often still resides in the place and context in which the ceramic product was originally made. Overall, the book argues that UK ceramics remain culturally complex because of issues of supply and demand, and ties to heritage, imagined or otherwise. Within a context of globalization, the book highlights compelling issues which have huge ramifications on UK manufacturing futures.
Seasonality in the Δ33S measured in urban aerosols highlights an additional oxidation pathway for atmospheric SO2
Authors: Au Yang David , Cartigny Pierre , Desboeufs Karine , Wîdory David
Published: October 2018

Abstract. Sulfates present in urban aerosols collected worldwide usually exhibit significant non-zero Δ33S signatures (from −0.6 to 0.5 ‰) whose origin still remains unclear. To better address this issue, we recorded the seasonal variations of the multiple sulfur isotope compositions of PM10 aerosols collected over the year 2013 at five stations within the Montreal Island (Canada), each characterized by distinct types and levels of pollution. The δ34S-values (n = 155) vary from 2.0 to 11.3 ‰ (± 0.2 ‰, 2σ), the Δ33S-values from −0.080 to 0.341 ‰ (± 0.01 ‰, 2σ) and the Δ36S-values from −1.082 to 1.751 ‰ (± 0.2 ‰, 2σ). Our study evidences a seasonality for both the δ34S and Δ33S, which can be observed either when considering all monitoring stations or, to a lesser degree, when considering them individually. Among them, the monitoring station located at the most western end of the island, upstream of local emissions, yields the lowest mean δ34S coupled to the highest mean Δ33S-values. The Δ33S-values are higher during both summer and winter, and are
Middle Miocene climate of southwestern Anatolia from multiple botanical proxies
Authors: Bouchal Johannes Martin , Güner Tuncay Hüseyin , Denk Thomas
Published: October 2018

Abstract. The middle Miocene climate transition (MMCT) was a phase of global cooling
possibly linked to decreasing levels of atmospheric CO2. The MMCT
coincided with the European Mammal Faunal Zone MN6. From this time, important
biogeographic links between Anatolia and eastern Africa include the hominid
Kenyapithecus. Vertebrate fossils suggested mixed open and forested
landscapes under (sub)tropical seasonal climates for Anatolia. Here, we infer
the palaeoclimate during the MMCT and the succeeding cooling phase for a
middle Miocene (14.8–13.2 Ma) intramontane basin in southwestern Anatolia
using three palaeobotanical proxies: (i) Köppen signatures based on the
nearest living-relative principle; (ii) leaf physiognomy analysed with the
Climate Leaf Analysis Multivariate Program (CLAMP); (iii) genus-level
biogeographic affinities of fossil flora with modern regions.
The three proxies reject tropical and hot subtropical climates for the MMCT
of southwestern Anatolia and instead infer mild warm temperate
C climates.
Köppen signatures reject summer-dry Cs climates but cannot discriminate
between fully humid Cf and winter-dry Cw; CLAMP reconstructs Cf climate based on
the low X3.wet∕X3.dry ratio. Additionally, we assess whether the
palaeobotanical record resolves transitions from the warm Miocene
Climatic Optimum (MCO, 16.8–14.7 Ma) to the MMCT (14.7–13.9 Ma), and a
more pronounced cooling at 13.9–13.8 Ma, as reconstructed from benthic
stable isotope data. For southwestern Anatolia, we find that arboreal taxa
predominate in MCO flora (MN5), whereas in MMCT flora (MN6) abundances of
arboreal and non-arboreal elements strongly fluctuate, indicating higher
structural complexity of the vegetation. Our data show a distinct pollen
zone between MN6 and MN7+8 dominated by herbaceous taxa. The
boundary between MN6
and MN7+8, roughly corresponding to a first abrupt cooling at 13.9–13.8 Ma,
might be associated with this herb-rich pollen zone.
IMEX_SfloW2D 1.0. A depth-averaged numerical flow model for
pyroclastic avalanches
Authors: de' Michieli Vitturi Mattia , Esposti Ongaro Tomaso , Lari Giacomo , Aravena Alvaro
Published: October 2018

Abstract. Pyroclastic avalanches are a type of granular flow generated at active volcanoes by different mechanisms, including the collapse of steep pyroclastic deposits (e.g., scoria and ash cones) and fountaining during moderately explosive eruptions. They represent end-members of gravity-driven pyroclastic flows, characterized by relatively small volumes (less than about 1 Mm3) and relatively thin (1–10 m) layers at high particle concentration (1–50 vol.%), manifesting strong topographic control. The simulation of their dynamics and mapping of their hazards pose several different problems to researchers and practitioners, mostly due to the complex and still poorly understood rheology of the polydisperse granular mixture, and to the interaction with the complex natural three-dimensional topography, which often causes rapid rheological changes. In this paper, we present IMEX_SfloW2D, a depth-averaged flow model describing the granular mixture as a single-phase granular fluid. The model is formulated in absolute Cartesian coordinates (where the fluid flow equations are integrated along the direction of gravity) and can be solved over a topography described by a Digital Elevation Model. The numerical discretization and solution algorithms are formulated to allow a robust description of wet-dry conditions (thus allowing to accurately track the front propagation) and to implicitly solve the non-linear friction terms. Owing to these features, the model is able to reproduce steady solutions, such as the triggering and stopping phases of the flow, without the need of empirical conditions. Benchmark cases are discussed to verify the numerical code implementation and to demonstrate the main features of the new model. A preliminary application to the simulation of the February 11th pyroclastic avalanche at Etna volcano (Italy) is finally presented. In the present formulation, a simple semi-empirical friction model (Voellmy-Salm rheology) is implemented. However, the modular structure of the code facilitates the implementation of more specific and calibrated rheological models for pyroclastic avalanches.
Large carbon cycle sensitivities to climate across a permafrost thaw gradient in subarctic
Sweden

Published: October 2018

Abstract. Permafrost peatlands store large amounts of carbon potentially vulnerable to decomposition. However, the fate of that carbon in a changing climate remains uncertain in models due to complex interactions among hydrological, biogeochemical, microbial, and plant processes. In this study, we estimated effects of climate forcing biases present in global climate reanalysis products on carbon cycle predictions at a thawing permafrost peatland in subarctic Sweden. The analysis was conducted with a comprehensive biogeochemical model (ecosys) across a permafrost thaw gradient encompassing intact palsa with an ice core and a shallow active layer, partly thawed bog with a deeper active layer and a variable water table, and fully thawed fen with a water table close to the surface, each with distinct vegetation and microbiota. Using in situ observations to correct local cold and wet biases found in the Global Soil Wetness Project Phase 3 (GSWP3) climate reanalysis forcing, we evaluated our model performance by comparing predicted and observed carbon dioxide (CO2) and methane (CH4) exchanges, thaw depth, and water table depth. The simulations driven by the bias-corrected climate suggest that the three peatland types currently accumulate carbon from the atmosphere, although the bog and fen sites can have annual positive radiative forcing impacts due to their higher CH4 emissions. Our simulations indicate that projected precipitation increases could accelerate CH4 emissions from the palsa area, even without further degradation of palsa permafrost. The GSWP3 cold and wet biases for this site significantly alter simulation results and lead to erroneous active layer depth and carbon budget estimates. Biases in simulated CO2 and CH4 exchanges from biased climate forcing are as large as those among the thaw stages themselves at a landscape scale across the examined permafrost thaw gradient. Future studies should thus not only focus on changes in carbon budget associated with morphological changes in thawing permafrost, but also recognize the effects of climate forcing uncertainty on carbon cycling.

How Dutch Aldermen experience their Authority.

Over the last four years, one in five Dutch aldermen was forced to step down involuntarily. Drawing on a survey among the 2018 population of these local political-executives, the article evaluates office holders’ self-perceived authority in four authorizing environments, that is the municipal council, the municipal board, among civil servants, and among citizens. The results show that, contrary to the authority-crisis thesis, Dutch aldermen perceive quite a high level of authority overall. Current office holders name trustworthiness as their main source of authority, followed by their personal style in executing their tasks and their moral leadership. This finding illustrates the individualization of contemporary authority at the expense of institutional and positional sources of authority.

ON THE DEVELOPMENT OF LATTICE BOLTZMANN MODELING FOR LIQUID-SOLID PHASE TRANSITIONS IN FREE SURFACE FLOWS
Authors: B Ayurzana , Hosoyamada Tokuzo , E Tungalagtamir , G Batzorig
Published: October 2018

Motivated by the current lack of knowledge regarding phase transition in a free surface water flow, a novel and efficient numerical model for liquid-solid phase transition in a free surface flow has been developed for the Lattice Boltzmann Method (LBM). The proposed model consists of two physically sound modules for solving free surface flow and heat transport. The heat transport module features an immersed boundary method and a non-iterative enthalpy-based approach. Sub-cycling time integration, improving the numerical stability of the heat transport module, is introduced for the integration of modules. The performance and accuracy of the model are verified through a preliminary experiment involving a melting ice cube. The obtained results indicate that the phase transition of fluid in any flow regime can be easily handled by the model with reasonable accuracy.
Marketing Research in the 21st Century: Opportunities and Challenges
Authors: Hair Jr. Joseph F. , Harrison Dana E. , Risher Jeffrey J.
Published: October 2018

The role of marketing for consumers and businesses is rapidly evolving (Ferrell, Hair, Marshall Tamilia 2015). Indeed, the marketing function is fundamentally changing as a result of the digital transformation, data, data analytics and most recently, personal mobile devices, such as infusion software, which track time as individuals work or play, can search for local businesses or customers while in a coffee shop, send an invoice or quote from a clients office, and much more (Shah et al 2014). Marketing research design and analysis methods are also changing rapidly (Hair, Black, Babin Anderson 2019). These changes are emerging from transformations in management skills (Henke, Levine McInerney 2018; Davenport 2018), technological innovation, particularly in the digital space (Davenport 2018), and continuously evolving customer behavior (needs and expectations) (Wedel Kannan 2016). To continue being relevant, marketing research must remain as dynamic as the markets themselves.
Strategic Actions in the Face of Uncertainty
Authors: Schoemaker Paul J.H. , Day George S.
Published: October 2018

In the face of volatile change and mounting uncertainty, firms may have to adapt rapidly. We highlight the mandates of strategic leaders who know how to develop organizational capabilities that allow for fast as well as slow action as circumstances dictate. In a world where unexpected twists and turns can overturn the most iron-clad handbook of standard operating procedures, strategic leaders remain a final, crucial line of defense. Once organizations have sensed incipient change in their environment, and understand its potential impact better, the question becomes what to do practically.
Decision Making Support for Managers In Innovation Management: a PROMETHEE approach
Authors: Peterková Jindra , Franek Jiří
Published: October 2018

The purpose of this paper is to present a decision making model as a support for selection of innovation management concept using multiple criteria decision-making methods. Defined innovation management concepts are evaluated using set of criteria, which priorities are expertly evaluated using analytic hierarchy process (AHP) and then the PROMETHEE method is used for evaluating and selecting variants. Based on the specific nature of innovation management concepts a novel decision making model was conceived. The model was imported to the Visual PROMETHEE software tool. The model was applied on a medium sized manufacturing company. The innovation concepts were evaluated and ranked. For this company the concept of value analysis was selected as the best. This study is limited for decision-making processes in medium and large sized companies. The results of AHP are based on expert but subjective assessment and therefore relevant for this particular company at that particular time. In addition, it is shown that this approach can help managers to solve similar decision-making problems using combination of AHP and software Visual PROMETHEE. The logic and process of the decision making model elaboration as much as the decision model itself can be used as a framework for managers facing decision making problems with similar nature as innovation management concepts i.e.: ERP systems, information systems, technologies, business models.

The analysis of strength and fracture
morphology of Al-Si compound made from
moulding sand formulation with bentonite
binding material and Portland cement
Authors: Andoko F , Puspitasari P. , Gapsari F.
Published: October 2018

Purpose: This research aimed to analyse the casting result of Al-Si compound used
formulation of moulding sand with bentonite binding material and Portland cement.
Design/methodology/approach: Bentonite binding material’s type consisted of swelling
(Na-bentonite) and non-swelling (Ca-bentonite). Optimum formulation of the moulding sand
was 4% of swelling bentonite and 6% of Portland cement, 6% of non-swelling bentonite
and 4% of Portland cement. The optimum formulation result of molding sand with bentonite
binding material and Portland cement was used in Al-Si compound casting. The result
of Al-Si compound casting strength was examined which in terms of its tensile strength,
toughness, and hardness. Besides the three tests, the result was also supported by the
fracture shape morphology of tensile test and impact toughness test result. Based on the
Al-Si compound tensile test result, it was found that the best value was obtained when using
105.52 MPa of swelling bentonite.
Findings: The impact toughness test result presented that the use of non-swelling bentonite
produced better toughness value which was 0.00592 J/hour while the mickroVickers
hardness test result showed that Al-Si compound result using non-swelling bentonite
produced 111.04 HV hardness. Based on the fracture morphology test result using SEM of
Al-Si compound casting result using swelling and non-swelling bentonite after being tested
its tensile strength and impact toughness showed that the same fracture which was brittle
fracture tended to appear.
Research limitations/implications: In this casting process, combination which is being
used is bentonite (swelling and non-swelling) and Portland cement as mould sand binding
material.
Practical implications: The combination can be used to find the bentonite type that can
produce binding material formula with high binding level which can minimize defects on the
resulted casting products.
Originality/value: In this study swelling and non-swelling bentonite mixed with certain
level of Portland cement combination are used.
Effect of shot peening on microstructure,
hardness, and corrosion resistance
of AISI 316L
Authors: Iswanto P.T. , Akhyar H. , Faqihudin A.
Published: October 2018

Purpose: This research conducted to analyse the effect of shot peening on surface
structure, hardness, and resistance to corrosion of AISI 316L.
Design/methodology/approach: The shot peening process is carried out on the surface
of 316L stainless steel samples with four peening durations, and they are 2, 4, 15, and 30
minutes. Shot ball steel with diameter 0.4 mm for metal shot blasting and model S110 of
ISO 11124/3 and SAEJ827, with the chemical composition, are C (0.8-1.2 wt.%), Mn (0.6-1.2
wt.%), Si (min. 0.4 wt.%), S (max. 0.05 wt.%), P (max. 0.05 wt.%), with a hardness of steelball,
about 40-50 HRC. The pressure of compressor kept constant at 8 bar with a diameter
of the nozzle is 5 mm, and the distance between the nozzle and the sample surface variated
by 6 cm and 12 cm for each shooting duration.
Findings: The result shows that the shot peening increases the surface hardness of the
material, changes the microstructure on the surface layer and increases the resistance to
corrosion. Shot peening with 30 minutes of shooting duration and 6 cm of shooting distance
can improve the metal surface properties, which has a surface hardness of 772.23 HV and
good on corrosion resistance.
Research limitations/implications: The results of this experiment show that shot
peening distance of 6 cm for 30 minutes achieved the highest surface hardness of AISI 316L.
The corrosion rate decline with increasing duration and nearer distance of shooting balls.
Practical implications: In the development of the implant material, AISI 316L need to be
improved, its material properties, so it can be used safely and compatibly. Shot peening is a
cold working process of metal to increase the material properties by shooting the steel ball
into the surface of a material.
Originality/value: Based on the experimental results it was obtained that variations shot
peening distance and shot peening duration can change grain morphologies, subsequently
affect hardness and corrosion resistance on AISI 316L.

FUNCTIONAL FOOD – A CHALLANGE FOR THE CONSUMER, OPPORTUNITY FOR PRODUCERS
Authors: Mironiuk Katarzyna
Published: October 2018

Pro-health trend dominates all over the world, as well in Poland. Nutrition education is present from
the early stages of our lives, which gradually creates healthy food conscious consumer. They are led to
choose their nutrition in a way to prevent diseases of affluence, therefore there is a need for functional
foods. Nowadays, together with the lack of definition of those products and with absence of dedicated to
them law, consumers experience problems with identifying this type food correctly. Producers, on the other
hand, are obligated to conduct complicated and expensive research to be able to set functional foods on the
market. The social attitudes towards necessity and price of those products seems positive. Current feasible
trends could be a chance for agribusiness and manufacturers to step in, listen to the consumers doubts and
troubles and prepare products that not only would be an answer for markets needs, but also would meet
diet recommendations. Such conjoint actions, together with well designed marketing strategy could build
a market ready for getting functional food regularly in the future. There is also a need observed among
consumers to design special mark, helping in distinguish between functional and conventional products.

Comunidades negras no Ceará: da invisibilidade à formação dos quilombos contemporâneos
Authors: Chaves Leilane Oliveira , Silva Edson Vicente
Published: October 2018

As comunidades quilombolas obtiveram maior visibilidade face às reivindicações de diversos segmentos sociais e principalmente do envolvimento dos quilombolas pelo direito de se auto definirem. Esses grupos formaram-se a partir do século XVI, como forma de resistência às condições de vida e de trabalho. No presente, compreendem diferentes contextos de posse de terras por populações predominantemente negras ou de seus descendentes no país. Desta forma, busca-se analisar o discurso da invisibilidade da presença negra no estado do Ceará frente ao reconhecimento de comunidades quilombolas contemporâneas. A pesquisa efetivada ancorou-se em levantamentos bibliográficas, conhecimentos empíricos, censos populacionais e instrumentos legais reunindo considerações sobre os principais conflitos que permeiam a auto definição desses grupos. Acredita-se que o trabalho é uma importante contribuição para a visibilidade do movimento quilombola cearense.
Agricultura de corte e queima e alternativas agroecológicas na Amazônia
Authors: Rego Anna Karyne Costa , Kato Osvaldo Ryohei
Published: October 2018

Esse artigo tem por objetivo apresentar a principal forma de uso do solo pelos agricultores da Amazônia, bem como as alternativas de produção baseadas nos princípios agroecológicos através de levantamento bibliográfico. A agricultura é identificada com a principal causadora do desmatamento na região devido ao corte e a queima da vegetação como principal forma de preparo de áreas para o cultivo. Essa prática consiste em derrubar e queimar a vegetação para a implantação de cultivos agrícolas por dois ou três anos, posteriormente a área é deixada em pousio para o estabelecimento da vegetação secundária e o solo retome sua capacidade produtiva. No entanto, com o crescimento populacional e a necessidade de geração de alimentos essa prática tornou-se insustentável devido apresentar períodos de pousio cada vez mais curtos. Com isso, o desenvolvimento de novas formas de cultivo sustentável tornou-se necessário.

Published: October 2018

Objectives: Secondary trauma is one of the main
causes of root fracture in regenerative endodontic cases. The aim of this study was to compare the influence of
placing Biodentine as a barrier material at different thicknesses on the
fracture strength of simulated immature teeth.

Materials and Methods: The root canals of 65 human maxillary
central incisors were instrumented using Peeso reamers to simulate immature
teeth. Ten teeth were assigned to the negative control group and received no
access cavity preparation. The access cavities of the remaining 55 teeth were
prepared. Among them, the root canals of 10 teeth were filled with calcium
hydroxide to serve as the positive control. Forty-five teeth were randomly distributed
into 3 groups (n=15); Group 1: 2-3 mm thick coronal plug, Group 2: 5-6 mm thick
coronal plug, Group 3: complete obturation. After the storage period, fracture
testing was performed using a universal testing machine. One-way analysis of
variance and Tukey tests were used to analyze the data.

Results: No significant difference was found among
the positive control, group 1 and group 2 (P
> 0.05). The negative control and group 3 presented the highest fracture strength
values (P < 0.05), while there was
no significant difference between them (P
> 0.05). All fractures occurred through the cervical region of the root
horizontally or obliquely.

Conclusions: No significant reinforcement effect was
obtained when Biodentine was used as a coronal plug. The complete root canal
obturation of simulated immature teeth using Biodentine provided the best
reinforcement effect. The coronal plug thickness had no influence on the
fracture strength of immature teeth.

Extreme degeneracy of inputs in firing a neuron leads to loss of information when neuronal firing is examined
Authors: Vadakkan Kunjumon I
Published: October 2018

Possible combinations of inputs in the order of 10100 can fire (axonal spike or action potential) a neuron that has nearly 104 inputs (dendritic spines). This extreme degeneracy of inputs that can fire a neuron is associated with significant loss of information when examination is limited to neuronal firing. Excitatory postsynaptic potentials (EPSPs) propagating from remote locations on the dendritic tree attenuate as they arrive at the axon hillock depending on the distance they propagate. Moreover, some EPSPs from remote locations will not even reach the axonal hillock. In this context, an operational mechanism at the location of origin of these EPSPs is necessary to preserve information for efficient storage. A similar mechanism is also expected at the location of origin of EPSPs generating dendritic spikes.
Humanity and the 21st century’s resource gauntlet: a commentary on Ripple et al.’s article “World Scientists’ Warning to Humanity: a Second Notice”

Published: October 2018

The 21st century will undeniably represent a major turn in the development of human societies, as Earth’s limiting resources can no longer support the current pace of material consumption (supplemental file S1). In this context, Ripple et al. (2017) identified thirteen critical shifts in our ways of life to reduce humanity’s ecological footprint and achieve sustainable development. While we endorse the pertinence and urgency of this call, we direct attention to critical shortcomings in the proposed solutions, which limit their potential to promote sustainability. Indeed, several prescriptions in Ripple et al. address symptoms rather than root causes, or seem to result from a simplistic consideration of inherently complex processes. We emphasize the importance of accounting for historical patterns and underlying drivers of the global socio-economic system, especially in relation to wealth inequality, human demography, and food production, which need deeper consideration than presently given in the warning and subsequent follow-up articles. Without such considerations, this second warning to humanity can be interpreted as prescriptive suggestions from a narrow, western-biased vision of the global socio-ecosystem, rendering it all but ineffective.
Feedback regulation of cytoneme-mediated transport shapes a tissue-specific FGF morphogen gradient
Authors: Du Lijuan , Sohr Alex , Yan Ge , Roy Sougata
Published: October 2018

Gradients of signaling proteins are essential for inducing tissue morphogenesis. However, mechanisms of gradient formation remain controversial. Here we characterized the distribution of fluorescently-tagged signaling proteins, FGF and FGFR, expressed at physiological levels from the genomic knock-in alleles in Drosophila. FGF produced in the larval wing imaginal-disc moves to the air-sac-primordium (ASP) through FGFR-containing cytonemes that extend from the ASP to contact the wing-disc source. The number of FGF-receiving cytonemes extended by ASP cells decreases gradually with increasing distance from the source, generating a recipient-specific FGF gradient. Acting as a morphogen in the ASP, FGF activates concentration-dependent gene expression, inducing pointed-P1 at higher and cut at lower levels. The transcription-factors Pointed-P1 and Cut antagonize each other and differentially regulate formation of FGFR-containing cytonemes, creating regions with higher-to-lower numbers of FGF-receiving cytonemes. These results reveal a robust mechanism where morphogens self-generate precise tissue-specific gradient contours through feedback regulation of cytoneme-mediated dispersion.
Adult nasolacrimal duct obstruction
Authors: Shermetaro Carl , Gladstone Geoffrey J.
Published: October 2018

Tear production resulting from obstruction of the nasolacrimal duct is a common ophthalmic problem. The diagnosis and treatment of this condition require a thorough understanding of the lacrimal apparatus and its ocular and nasal relationships. Idiopathic or primary acquired nasolacrimal duct obstruction is a syndrome of unknown etiology. Of all nontraumatic fonus, it accounts for the vast majority of cases found in adults. The authors discuss a number of potential causes, some of them iatrogenic and discuss the technique of dacryocystorhinostomy, the standard surgical treatment, in detail.

Published: October 2018

Soil organic carbon (SOC) is an important soil property that has profound impact on soil quality and plant growth. With 140 soil samples collected from Ebinur Lake Wetland National Nature Reserve, Xinjiang Uyghur Autonomous Region of China, this research evaluated the feasibility of visible/near infrared (VIS/NIR) spectroscopy data (350–2,500 nm) and simulated EO-1 Hyperion data to estimate SOC in arid wetland regions. Three machine learning algorithms including Ant Colony Optimization-interval Partial Least Squares (ACO-iPLS), Recursive Feature Elimination-Support Vector Machine (RF-SVM), and Random Forest (RF) were employed to select spectral features and further estimate SOC. Results indicated that the feature wavelengths pertaining to SOC were mainly within the ranges of 745–910 nm and 1,911–2,254 nm. The combination of RF-SVM and first derivative pre-processing produced the highest estimation accuracy with the optimal values of Rt (correlation coefficient of testing set), RMSEt and RPD of 0.91, 0.27% and 2.41, respectively. The simulated EO-1 Hyperion data combined with Support Vector Machine (SVM) based recursive feature elimination algorithm produced the most accurate estimate of SOC content. For the testing set, Rt was 0.79, RMSEt was 0.19%, and RPD was 1.61. This practice provides an efficient, low-cost approach with potentially high accuracy to estimate SOC contents and hence supports better management and protection strategies for desert wetland ecosystems.
Unscheduled HDAC4 repressive activity in human fibroblasts triggers TP53‐dependent senescence and favors cell transformation
Authors: Paluvai Harikrishnareddy , Di Giorgio Eros , Brancolini Claudio
Published: October 2018

Expression of the class IIa HDACs is frequently altered in different human cancers. In mouse models these transcriptional repressors can trigger transformation, acting as bona fide oncogenes. Whether class IIa HDACs also exhibit transforming activities in human cells is currently unknown. We infected primary human fibroblasts with retroviruses to investigate the transforming activity of HDAC4 in cooperation with well‐known oncogenes. We have discovered that HDAC4 triple mutant (S246A, S467A, S632A) (HDAC4‐TM), a nuclear resident version of the deacetylase, triggers TP53 stabilization and OIS (oncogene‐induced senescence). Unlike RAS, HDAC4‐induced OIS was TP53‐dependent and characterized by rapid cell cycle arrest and accumulation of an unusual pattern of γH2AX‐positive foci. The inactivation of both TP53 and of the retinoblastoma (pRb) tumor suppressors, as induced by the viral oncogenes large and small T of SV40, triggers anchorage‐independent growth in RAS, HDAC4‐TM and, to a lesser extent, in HDAC4‐wild type (WT)‐expressing cells. Our results suggest an oncogenic function of class IIa HDACs in human cells, and justify further efforts to discover and evaluate isoform‐specific inhibitors of these epigenetic regulators from a therapeutic perspective.

Perovskite solar cells (PSCs) with efficiencies greater than 20% have been realized mostly with expensive spiro‐MeOTAD hole‐transporting material. PSCs are demonstrated that achieve stabilized efficiencies exceeding 20% with straightforward low‐cost molecularly engineered copolymer poly(1‐(4‐hexylphenyl)‐2,5‐di(thiophen‐2‐yl)‐1H‐pyrrole) (PHPT‐py) based on Rutin–silver nanoparticles (AgNPs) as the hole extraction layer. The Rutin–AgNPs additive enables the creation of compact, highly conformal PHPT‐py layers that facilitate rapid carrier extraction and collection. The spiro‐MeOTAD‐based PSCs show comparable efficiency, although their operational stability is poor. This instability originated from potential‐induced degradation of the spiro‐MeOTAD/Au contact. The addition of conductive Rutin–AgNPs into PHPT‐py layer allows PSCs to retain >97% of their initial efficiency up to 60 d without encapsulation under relative humidity. The PHPT‐py/ Rutin–AgNPs‐based devices surpass the stability of spiro‐MeOTAD‐based PSCs and potentially reduce the fabrication cost of PSCs.
