AbstractThe ZrN‐SiAlON composite powder was synthesized using low‐grade zircon and bauxite by carbothermal reduction nitridation at first and then ZrN‐SiAlON‐SiC‐C composite refractory were fabricated with the ZrN‐SiAlON powder, SiC particles, and a small amount of Si powder as raw materials and sucrose as the binder. The slag resistance of these composites in O2, N2 and Ar atmosphere was investigated by X‐ray diffraction, scanning electron microscopy, and energy dispersion spectra. The results show that the pores in the inside of ZrN‐SiAlON‐SiC‐C composite refractory were enlarged in oxygen atmosphere due to oxidation, which leads to the decrease in slag resistance. In argon atmosphere, blast furnace slag destroyed the sintered body of zircon, corundum, and cristobalite with the formation of CaZrO3, then infiltrated into and filled the pores inside the refractory to form a dense layer, which hindered the further erosion of the blast furnace slag. In the reducing atmosphere, the interfacial energy of the gas‐liquid phases became larger due to the reactions between blast furnace slag liquid and the gas, resulting in a larger wetting angle which prevented the erosion.

AbstractIntroductionDrug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a severe drug‐induced reaction associated with eosinophilia and systemic manifestations. Anticonvulsants, sulfonamides, and antivirals are the most related and described drugs in DRESS syndrome.Methods and caseWe present a case of severe multiple organ dysfunction syndrome (MODS) with the risk of death associated with DRESS syndrome due to antileishmanial pentavalent antimonial drug and its simultaneous toxicity. Consequently, a comprehensive review of the main clinical problems and comparative discussion of both clinical conditions was made.DiscussionThe overlap of DRESS syndrome and antileishmanial pentavalent antimonial drug toxicity can be life‐threatening. Both conditions represent a true clinical, diagnostic, and therapeutic challenge. We exposed specific clinical and laboratory results with rare occurrence.ConclusionAny physician and dermatologists should keep in mind the broad spectrum of clinical manifestations and laboratory findings associated with the use of pentavalent antimonial drugs. The clinical suspicion, an early diagnosis, and aggressive treatment are essential to prevent complications and death.

Published: August 2018

AbstractTaking scented smoke baths (Dukhan) is a universal custom among African women who indulge in it for pleasure, cleanliness, health, and for restoration after childbirth. The woods used in this procedure are usually Acacia seyal and Terminalia brownii. This report is a case series of 11 women with brown‐erythematous excoriated papules, plaques, and lichenification confined to the sites of scented smoke baths. They were diagnosed with airborne contact dermatitis on the basis of patient history, existence of dust agents, the morphology and distribution of the lesions, the results of epicutaneous tests (repeated open application test), and avoidance of further exposure leading to recovery from dermatitis.

Abstract

Objectives
To investigate knowledge and attitudes of different healthcare professionals in UK towards infliximab and insulin glargine biosimilars

Methods
UK medical consultants/registrars, nurses and pharmacists participated in anonymised, self-administered web-based survey distributed by professional associations.

Key findings
There were 234 respondents: medical consultants/registrars (150), nurses (58) and pharmacists (26). 76% of medical consultants/registrars, 84% of pharmacists and 53% of nurses understood what biosimilars were. Medical consultants/registrars and pharmacists had safety and efficacy concerns when switching patients compared to initiation. Nurses had similar levels of safety and efficacy concerns about initiation.

Conclusion
Healthcare professionals were more comfortable with the initiation of biosimilars than switching current patients. Medical consultants/registrars and pharmacists were more informed than nurses.

AbstractAntibody‐mediated immunity is highly protective against disease. The majority of current vaccines confer protection through humoral immunity, but there is high variability in responsiveness across populations. Identifying immune mechanisms that mediate low antibody responsiveness may provide potential strategies to boost vaccine efficacy. Here, we report diverse antibody responsiveness to unadjuvanted as well as adjuvanted immunization in substrains of BALB/c mice, resulting in high and low antibody response phenotypes. Furthermore, these antibody phenotypes were not affected by changes in environmental factors such as the gut microbiota composition. Antigen‐specific B cells following immunization had a marked difference in capability to class switch, resulting in perturbed IgG isotype antibody production. In vitro, a B‐cell intrinsic defect in the regulation of class‐switch recombination was identified in mice with low IgG antibody production. Whole genome sequencing identified polymorphisms associated with the magnitude of antibody produced, and we propose candidate genes that may regulate isotype class‐switching capability. This study highlights that mice sourced from different vendors can have significantly altered humoral immune response profiles, and provides a resource to interrogate genetic regulators of antibody responsiveness. Together these results further our understanding of immune heterogeneity and suggest additional research on the genetic influences of adjuvanted vaccine strategies is warranted for enhancing vaccine efficacy.
Anti‐Corruption and Corporate Tax Burden: Evidence from China
Authors: Chen Yunsen , Zheng Dengjin , Li Peixin , Wang Weimin 
Published: August 2018

AbstractWe examine whether the Chinese government's anti‐corruption enforcement reduces corporate tax burdens. Using a difference‐in‐difference approach, we find tax burdens of firms located in corrupt political leaders’ jurisdictions are lower after these leaders were deposed. An analysis of two tax policy changes shows that the reduction in tax burden is more pronounced when corrupt politicians had more power in levying taxes.
A realization of excellent piezoelectricity and good thermal stability in CaBi2Nb2O9: Pseudo phase boundary
Authors: Liu Gang , Wang Dan , Wu Chao , Wu Jiagang , Chen Qiang 
Published: August 2018

AbstractPhase boundaries (PBs) are known to contribute to the outstanding performances of lead‐based and lead‐free materials. However, a lack of PBs restricts the promotion of piezoelectric performance in bismuth layer‐structured ferroelectrics (BLSFs). In this work, a pseudo PB, ie, pseudotetragonal distortion (regulated by Ce), is proposed to promote the piezoelectric properties of CaBi2Nb2O9‐based ceramics, and an excellent piezoelectric constant (d33) of 20.2 pC/N with a high Curie temperature of 923°C is obtained. Verified Ce incorporation into the (Bi2O2)2+ layer alters the environment of the (Bi2O2)2+ layer, thereby influencing the atomic displacement in the Nb‐O octahedron and modulating the theoretical spontaneous polarization (Ps). Strengthening of the pseudotetragonal distortion is favorable to the polarization switching, and maintains the theoretical Ps of ceramics at a high level, thus realizing the promotion of d33. Furthermore, pseudotetragonal distortion guarantees good thermal depoling performance of the ceramic, which remains at 89.6% (18.1 pC/N) of its initial d33 after depoling at 875°C. This work provides clear guidance on obtaining high d33 and good thermal stability in BLSFs.
Flash sintering with current rate: A different approach
Authors: Kumar M K Punith , Yadav Devinder , Lebrun Jean‐Marie , Raj Rishi 
Published: August 2018

AbstractThe original flash sintering experiment was carried out by applying an electric field, and switching to current control at the onset of the flash, signaled by a rise in conductivity. Here, we consider experiments where the experiment is controlled from the very start, by injecting current, which is increased at a constant rate. The current rates are varied from 50 mA/min to 5000 mA/min. The experiment is continued until, in all cases, the current density reaches 100 mA/mm2. The total duration of the experiment ranged from approximately 7 seconds to 700 seconds. The following comparisons to the earlier voltage‐to‐current experiments are noted: (a) in both instances, the onset of the flash is signaled by an unusual rise in conductivity; however, since the power supply remains in the current control mode, the increase in conductivity is manifested by a drop in the voltage generated across the specimen; (b) the blackbody radiation model is modified to include the energy absorbed in specific heat, in order to determine the time‐dependent change in temperature as the current is increased—this correction is particularly significant at the very high current rates; (c) sintering occurs continuously, reaching full density, in all instances, when the current density reaches ~100 mA/mm2; and (d) these early experiments suggest that the current‐rate experiments yield fine‐grained microstructure across the entire gauge section of the dog‐bone specimen, presumably because the highly transient conditions of voltage‐to‐current flash experiments are sidestepped. The experiments were carried out on 3 mol% yttria‐stabilized zirconia.

AbstractAimSpecies’ distributions and abundances are primarily determined by the suitability of environmental conditions, including climate and interactions with sympatric species, but also increasingly by human activities. Modelling tools can help in assessing the extinction risk of affected species. By combining species distribution modelling of abiotic and biotic niches with population size modelling, we estimated the abundance of 19 lemur taxa in three regions, especially focusing on 10 species that are considered Endangered or Critically Endangered.LocationMadagascar.TaxaLemurs (Primates) and angiosperm trees.MethodsWe used climate data, field samples, and published occurrence data on trees to construct species distribution models (SDM) for lemur food tree species. We then inferred the SDMs for lemurs based on the probability of occurrence of their food trees as well as climate. Finally, we used tree SDMs, topography, distance to the forest edge, and field estimates of lemur population density to predict lemur abundance in general linear models.ResultsThe SDMs of lemur food trees were stronger predictors of the occurrence of lemurs than climate. The predicted probability of presence of food trees, slope, elevation, and distance from the forest edge were significant correlates of lemur density. We found that sixteen species had minimum estimated abundances greater than 10,000 individuals over >1,000km2. Three lemur species are especially threatened, with less than 2,500 individuals predicted for Cheirogaleus sibreei, and heavy hunting pressure for the relatively small populations of Indri indri and Hapalemur occidentalis.Main conclusionsBiotic interactors were important variables in SDMs for lemurs, allowing refined estimates of ranges and abundances. This paper provides an analytical workflow that can be applied to other taxonomic groups to substantiate estimates of species’ vulnerability to extinction.
Community‐based mealtime management for adolescents with anorexia nervosa: A qualitative study of clinicians’ perspectives and experiences
Authors: Watt Jaclyn , Dickens Geoffrey L. 
Published: August 2018

AbstractBackground and ObjectiveCommunity‐based mealtime management is an intensive, focused, and time‐limited intervention for young people with an eating disorder which aims to support refeeding at home and thus prevent hospital admission. Little is known about clinicians’ experiences of delivering this intervention. We aimed to explore mental health clinicians’ perspectives on community mealtime management with children and adolescents diagnosed with an eating disorder.MethodsA qualitative design was used. Semistructured interviews were conducted with six mental health clinicians with experience of delivering or referral for the intervention. Interview recordings were transcribed and subjected to a thematic analysis.ResultsAnalysis resulted in identification of three themes: (a) technical aspects of mealtime management, (b) emotional aspects of mealtime management, and (c) a mixed zone of uncertainty around the use of dietary supplements. Overall, participants believed mealtime management to be a valuable intervention.ConclusionsFindings highlight the perceived need for more formal training for clinicians undertaking mealtime management, and the positive impact this could potentially have on their practice. Clinicians’ emotion regulation during intervention delivery was perceived to be important. There was a perceived need for greater adherence to protocols but an acceptance that flexibility was also required.

Published: August 2018

AbstractRaclette cheeses arranged in racks were ripened in an industrial ripening room under temperature, relative humidity, and air circulation control. Cheese mass loss was investigated via two ripening trials and by weighing nine racks located at chosen places in the ripening room. Air velocity (varying from 0.06 to 0.48 m/s as a function of the distance of the textile ventilation ducts that ensure air circulation) had the greatest effect on mass loss (changing from 4.1 to 8.7% of the initial mass). The higher the air velocity was, the greater the cheese mass loss was. The racks at the top of the stacks significantly exhibited the highest mass loss. Linear and exponential relationships between mean cheese mass loss rate and air velocity are proposed. Compared to continuous ventilation, time‐based sequential ventilation led to a mean reduction of mass loss of about 0.75% and confirmed a reduction in energy consumption (about 42%).Practical applicationsThe control of air circulation in industrial cheese ripening rooms is difficult, and considerable heterogeneities in air velocity are often observed. The higher the air velocity is, the greater the cheese mass loss will be, so it is important to know the air velocity distribution inside the ripening room and to obtain and maintain air velocities close to 0.08 m/s, thus favoring homogeneous cheese mass loss. Knowledge of the variations in cheese mass loss as a function of the ripening conditions and of the changes in air velocity must be improved so that cheese‐makers can limit mass loss while maintaining ripened cheese quality, as well as significantly increasing cheesemaking yield.Opting for sequential ventilation (a time or temperature‐based process) at the industrial cheese ripening scale can provide economic benefits by reducing energy consumption and decreasing cheese mass loss.

Published: August 2018

AbstractModeling of moisture content variation under variable microwave power in microwave‐hot air dryer is challenging. In this study, one static and one dynamic of ANN were investigated for modeling of whole mushroom drying process. The experiments were done in three levels of hot air temperature (23, 50, and 70 °C), three levels of microwave power density (MPD) (1.5, 2, and 2.5 W/g) and two statuses of microwave power during drying process (constant and variable). The results demonstrated that the two distinct falling rate periods were observed at low MPD with any air temperatures and power density status. The lowest specific energy consumption was found in 23 °C and 2.5 fixed MPD and lowest color deterioration found in 70 °C and 1.5 fixed MPD. The results also showed the 3–6–7–1 structure of dynamic model with 0.2179 RMSE and 0.9914 R values had better results than other structures and would be very suitable in a predictive control system for drying control.Practical applications
Volumetric and high efficiency heating are the primary benefit of microwave drying and lot of industries and producers interest to use it. Also, modeling of drying kinetics and evaluating of product quality in each drying method provide valuable information to improve their drawbacks and recommend it for industry. Application of microwave technology in dehydration of mushroom can result in significant improvement in quality and energy consumption. On the other hand investigating a robust ANN model for predicting the moisture content helps to better prediction and control of microwave‐hot air dryer in industrial scale.

Abstract
Escherichia coli is an important pollution indicator and is the most important foodborne pathogens of public health concern. The chicken meat is one of the most important sources of good quality protein, and it is also susceptible to microbial contamination and often implicated in foodborne disease. In such context, the detection of E. coli K12 in frozen chicken meat was investigated by electrochemical impedance spectroscopy and surface plasmon resonance imaging techniques. The anti‐E. coli antibody was first immobilized onto gold surface by physisorption technique. The electrical and optical properties of the immobilized anti‐E. coli K12 antibody were studied. The binding of the E. coli K12 bacteria with the anti‐E. coli antibody layer was measured with a detection limit of 103 cfu/ml. This detection limit is better than those obtained with the enzyme‐linked immunosorbent assay (ELISA) technique. Moreover, the developed biosensor was used for E. coli K12 detection in inoculated frozen chicken meat.Practical applications
Escherichia coli is an important pollution indicator and is the most important foodborne pathogens of public health concern. The present study deals with the development of bacteria biosensors based on electrochemical impedance spectroscopy and surface plasmon resonance imaging techniques for E. coli K12 detection in inoculated frozen chicken meat. A detection limit of 103 cfu/ml was obtained with the developed biosensors that was better than those obtained with classical methods such as ELISA (enzyme‐linked immunosorbent assay). This research work opens tremendous potential applications for the detection of pathogens in food at the early stage particularly with the development of miniaturized multiarrays platform based on impedance spectroscopy.

Published: August 2018

SummaryStructured‐illumination microscopy allows widefield fluorescence imaging with resolution beyond the classical diffraction limit. Its linear form extends resolution by a factor of two, and its nonlinear form by an in‐principle infinite factor, the effective resolution in practice being determined by noise. In this paper, we analyse the noise properties and achievable resolution of linear and nonlinear 1D and 2D patterned SIM from a frequency–space perspective. We develop an analytical theory for a general case of linear or nonlinear fluorescent imaging, and verify the analytical calculations with numerical simulation for a special case where nonlinearity is produced by photoswitching of fluorescent labels. We compare the performance of two alternative implementations, using either two‐dimensional (2D) illumination patterns or sequentially rotated one‐dimensional (ID) patterns. We show that 1D patterns are advantageous in the linear case, and that in the nonlinear case 2D patterns provide a slight signal‐to‐noise advantage under idealised conditions, but perform worse than 1D patterns in the presence of nonswitchable fluorescent background.Lay DescriptionStructured‐illumination microscopy (SIM) is a high‐resolution light microscopy technique that allows imaging of fluorescence at a resolution about twice the classical diffraction limit. There are various ways that the illumination can be structured, but it is not obvious how the choice of illumination pattern affects the final image quality, especially in view of the noise. We present a detailed performance analysis considering two illumination techniques: sequential illumination with line‐gratings that are shifted and rotated during image acquisition and two‐dimensional (2D) illumination structures requiring only shift operations. Our analysis is based on analytical theory, supported by simulations of images considering noise. We also extend our analysis to a nonlinear variant of SIM, with which enhanced resolution can be achieved, limited only by noise. This includes nonlinear SIM based on the light‐induced switching of the fluorescent molecules between a bright and a dark state. We find sequential illumination with line‐gratings to be advantageous in ordinary (linear) SIM, whereas 2D patterns provides a slight signal‐to‐noise advantage under idealised conditions in nonlinear SIM if there is no nonswitching background.
