Synthesis of multitask star‐shaped oligoaniline: Introducing a novel, efficient epoxy hardener
Authors: Shahkarami F. , Moini N. , Kabiri K. , Piri F. , Jahandideh A. 
Published: April 2023

AbstractMultitask star‐shaped oligoaniline (S‐TAH) was synthesized using microwave irradiation in three steps: preparation of phthalic acid‐ capped tetra‐aniline (as the arm), synthesis of a tetrafunctional biobased core, and subsequently, coupling arms to the core, using a divergent approach. A biobased core was synthesized through a direct condensation reaction of pentaerythritol, with l‐lactic acid. The chemical structures were extensively characterized using Fourier‐transform infrared and proton nuclear magnetic resonance spectroscopy. The performance of S‐TAH, as a multitask hardener for bisphenol A‐based epoxy resin (EP), was evaluated using differential scanning calorimetry, thermal gravimetric analysis, dynamic thermomechanical analyses (DMTA), and four‐prob conductometry. Peaks of cure exotherms for S‐TAH/EP (1:1) systems appear at 135°C with a tail‐like peak around 175°C. Compared to conventional amine‐cured EP, the thermal stability of the S‐TAH/EP cured was significantly higher, that is, ~ 40°C enhancement in half weight loss temperature (T50). A three‐fold improvement in char yield was observed. From DMTA, the material cured with S‐TAH displays representative storage moduli in glassy (9.4 GPa) and rubbery (5.2 GPa) states reflecting a uniform network and viscoelastic behavior. The electrical conductivities (σ) of the pure S‐TAH and the epoxy systems cured with S‐TAH/EP are 4.3 × 10−4, and 2.65 × 10−4, respectively. T star‐shaped oligoaniline is a promising multitask hardener—functioning as hardener, thermal stabilizer, electrically conductive and toughening agents—which can be versatilely applied in thermal resistance anticorrosive coatings and conductive adhesives.
When mothers are more negative while fathers are less positive: Offspring's temporary feelings of depression affect parental work engagement via the asymmetric effects of emotions transmission
Authors: Lu Li , Wang Lei 
Published: April 2023

AbstractThere is a sharp rise in depressive moods from childhood to adolescence. Since moods can cross over from a child to a parent and spill over from family to work, offspring's temporary feelings of depression represent potential risks for parents' occupational health and well‐being. In the current study, the authors investigate the impacts of offspring's temporary feelings of depression on mothers' work engagement via the transfer of negative moods, and on fathers' work engagement via the transfer of positive moods. Participants were 265 full‐time employees and their adolescent offspring. The results confirmed our hypotheses. Offspring's temporary feelings of depression were associated with less maternal work engagement via increased maternal negative moods and endangered paternal work engagement via decreased paternal positive moods. The finding implies that negative emotions may be related to the occupational health of working mothers, while positive emotions may be related to the occupational health of working fathers.

Published: April 2023

AbstractThe Red Squirrel ammonia field experiments were conducted at the DNV Spadeadam site in the UK in 2022. Field test data currently exists for high‐pressure (ambient temperature) two‐phase releases of ammonia from Desert Tortoise (1983) and FLADIS (1996) experiments. No field tests have ever been done for cold (refrigerated) ammonia liquid spills on dry land or into water. The handling of liquified ammonia, during storage/processing and transportation, in a cold (refrigerated) state is inherently safer than in a high‐pressure (ambient temperature) liquified state. The main objective of the Air Products’ Red Squirrel Tests was to determine the source term and dispersion characteristics for high‐pressure (ambient temperature) liquified ammonia and low‐pressure (cold/refrigerated) liquified ammonia in form of two‐phase releases and liquid spills, respectively. Liquid spills on concrete and water were studied, along with the process conditions that led to the transition from liquid spills to two‐phase flow regimes based on discharge pressures for cold liquified ammonia. Details on the equipment, instrumentation, secondary containment, and ammonia sensors and their layout are presented. An initial analysis of the source terms and dispersion behavior for two‐phase releases and contained liquid spills over a range of weather conditions is also provided.
Dual action anti‐inflammatory/antiviral isoquinoline alkaloids as potent naturally occurring anti‐SARS‐CoV‐2 agents: A combined pharmacological and medicinal chemistry perspective
Authors: Valipour Mehdi , Hosseini Asieh , Di Sotto Antonella , Irannejad Hamid 
Published: April 2023

AbstractIn the search for compounds that inhibit the SARS‐CoV‐2 after the onset of the COVID‐19 pandemic, isoquinoline‐containing alkaloids have been identified as compounds with high potential to fight the disease. In addition to having strong antiviral activities, most of these alkaloids have significant anti‐inflammatory effects which are often manifested through the inhibition of a promising host‐based anti‐COVID‐19 target, the p38 MAPK signaling pathway. In the present review, our pharmacological and medicinal chemistry evaluation resulted in highlighting the potential of anti‐SARS‐CoV‐2 isoquinoline‐based alkaloids for the treatment of COVID‐19 patients. Considering critical parameters of the antiviral and anti‐inflammatory activities, mechanism of action, as well as toxicity/safety profile, we introduce the alkaloids emetine, cephaeline, and papaverine as high‐potential therapeutic agents for use in the treatment of COVID‐19. Although preclinical studies confirm that some isoquinoline‐based alkaloids reviewed in this study have a high potential to inhibit the SARS‐CoV‐2, their entry into drug regimens of COVID‐19 patients requires further clinical trial studies and toxicity evaluation.

SummaryThe finite‐time input‐to‐state stability () of stochastic impulsive time‐varying nonlinear systems is investigated in this paper. Different from the previous works concerning , we allow the coefficients of the estimated upper bound for the diffusion operator of a Lyapunov function to be time‐varying. Moreover, a relaxed relation between the impulsive frequency is provided. Leveraging the Lyapunov method along with Lambert function and average impulsive interval () method, the input‐to‐state () property is obtained within finite time. Furthermore, two examples are provided to verify the validity of the conclusion.
Sustainability as a strategy base in Spanish firms: Sustainability reports and performance on the sustainable development goals
Authors: Gutiérrez‐Ponce Herenia 
Published: April 2023

AbstractThis article examines corporate sustainability reports, the standards they use, and their connection to performance on the sustainable development goals (SDGs) from firms in the main Spanish stock index. The investigation was performed through an exploratory, descriptive, analytic study as well as examination of the disclosure and performance on the SDGs after Law 11/2018 went into effect in Spain. The study methods used include parametric correlations that explain the associations between the global reporting initiative (GRI) and environmental, social, and governance (ESG) standards and the level of performance on SDGs/ESG in the sustainability reports. We found that all firms present their verified sustainability reports, that the level of ESG information is above 75%, and that the GRI is the sustainability standard used. Further, all firms contribute on average a 75% level of information on all goals and on each of the 17 goals for the 2030 Agenda. We obtain significant analogies in level of disclosure of GRI‐ESG information and level of performance on the SDGs/ESG. In addition, the higher the level of information on environmental GRI standards, the better the firm's position in the environmental SDG ranking.

AbstractBackgroundThere is little currently little information available regarding the nature of the advice requests veterinary dermatologists receive from general practitioners. Collation of such data could direct continuing veterinary development in the future.MethodsDermatologists completed hand‐written recording sheets during or after enquiries. Information recorded included the route of enquiry, nature of advice, material provided, practice type and location, animal signalment, presenting signs, diagnosis/differential diagnosis, treatment and referral recommendations, time taken and if charges were made.ResultsTwelve dermatology services recorded 768 advice requests over a 6‐month period. Most requests were submitted via email and related to canine dermatology (81%). An average of 9.5 minutes was spent replying to requests. Charges were made in 2% of cases. Advice regarding otitis was most commonly sought, followed by pruritus, alopecia and crusting. The most frequently discussed diagnoses included allergy, otitis, pyoderma, demodicosis, dermatophytosis and neoplasia. Antibiotics, anti‐pruritics and topical otic medications were the most commonly discussed therapeutics.LimitationsThis is an initial study and therefore there are limitations involving the depth of the data. Additional studies should be completed which identify why advice is sought, decision‐making regarding referral, and if advice should be charged similarly to other disciplines.ConclusionsThese findings highlight that veterinarians mostly frequently seek advice on management of common dermatological problems, including allergy, otitis and pyoderma.
How to paint a bouquet: MA‐XRF analysis of 17th century Netherlandish flower still lifes from the Mauritshuis

Published: April 2023

AbstractThe Mauritshuis (The Hague, The Netherlands) owns a large collection of 17th‐century still lifes, of which a significant portion depicts floral arrangements. As part of a still life cataloguing project, 19 of the flower still lifes have been examined using a wide range of scientific technologies, including MA‐XRF scanning. This paper will discuss how MA‐XRF analysis has significantly improved our understanding of the way artists prepared their compositions. It became apparent that there are several ways in which artists planned their painted bouquets. Early 17th‐century still life painters such as Baltahasar van der Ast used detailed underdrawings, which they followed during the painting stage. Artists from Antwerp, like Daniël Seghers started their paintings by making ‘abstract’ compositions of coloured circles and ovals. This method was picked up by Jan Davidsz, de Heem, who was working in both Antwerp and Utrecht. De Heem's pupils Abraham Mignon and Maria van Oosterwijck used a similar method, but other still life specialists such as Van Aelst and Rachel Ruysch planned their compositions differently.
The influence of aperture on the imaging quality of microfocus x‐ray source
Authors: Dong Zengya , Shi Lina , Niu Geng , Wang Wenbo , Liu Junbiao , Han Li 
Published: April 2023

AbstractElectron beam (e‐beam) with a small spot size is the key to produce microfocus x‐ray source. The spot size of the e‐beam can be controlled by changing the aperture angle at the target, and the focus size of the microfocus x‐ray source is changed accordingly. At the same time, the SNR (Signal‐to‐Noise Ratio) of the image is reduced because the aperture produces secondary x‐ray, which interferes with the x‐ray imaging. In this paper, the aperture size and its position are optimized for getting the smallest spot size of the e‐beam, and the experimental results show that the resolution is 0.8 μm with the aperture size of 0.5 mm. In addition, this paper also presents that the image's SNR can be improved by coating carbon film on the back surface of the aperture.
Beyond “Dreydegger”: The Future of Anglo-American Existential Phenomenology
Authors: Londen Patrick 
Published: April 2023

AbstractAlthough there are many philosophers responsible for introducing phenomenology to philosophy departments in the United States and United Kingdom (e.g. Charles Taylor and Richard Rorty), arguably none has been as broadly influential as Hubert Dreyfus (1929–2017). It may not be too much of an exaggeration to claim (as some have; see Kelly, 2005), that the reading of Heidegger taught in most philosophy departments in the English-speaking world is some descendent of Dreyfus’s Heidegger—or “Dreydegger” as it is sometimes called. This portmanteau is at once a term of endearment and of derision. The union of the two thinkers represents some of the best of Dreyfus’s personal contributions to philosophy: the willingness to look to philosophical texts of the past for insights that can help untangle current theoretical problems; and the boldness in appropriating and reimagining the thinking of one of the most influential thinkers of the past century. But the term also stands for a certain style of reading texts in the history of philosophy that, some argue, gives short shrift to the historical context of the thinking that went into it, the life and legacy of the philosopher who wrote it, and most starkly, the original intentions of the text itself. As Marjorie Grene, a contemporary and colleague, remarked, Dreyfus “purveys his Heidegger, not wholly uncritically, but with deep intellectual passion and undoubted pedagogical brilliance to all—hundreds a year—who come to listen, and uses that Heidegger, in turn, for his own philosophical purposes” (Grene, 1976: 33).

Published: April 2023

AbstractFor a long time, the physiological activity of TRP ion channels and the response to various stimuli have been the focus of attention, and the physiological functions mediated by ion channels have subtle links with the occurrence of various diseases. Our group has been engaged in the study of ion channels. In recent years, the report rate of TRPA1, the only member of the TRPA subfamily in the newly described TRP channel, has been very high. TRPA1 channels are not only abundantly expressed in peptidergic nociceptors but are also found in many nonneuronal cell types and tissues, and through the regulation of Ca2+ influx, various neuropeptides and signaling pathways are involved in the regulation of nerves, respiration, circulation, and various diseases and inflammation throughout the body. In this review, we mainly summarize the effects of TRPA1 on various systems in the body, which not only allows us to have a more systematic and comprehensive understanding of TRPA1 but also facilitates more in-depth research on it in the future.

Abstract
Purpose
Patient-tailored management of thyroid nodules requires improved risk of malignancy stratification by accurate preoperative nodule assessment, aiming to personalize decisions concerning diagnostics and treatment. Here, we perform an exploratory pilot study to identify possible patterns on multispectral optoacoustic tomography (MSOT) for thyroid malignancy stratification. For the first time, we directly correlate MSOT images with histopathology data on a detailed level.

Methods
We use recently enhanced data processing and image reconstruction methods for MSOT to provide next-level image quality by means of improved spatial resolution and spectral contrast. We examine optoacoustic features in thyroid nodules associated with vascular patterns and correlate these directly with reference histopathology.

Results
Our methods show the ability to resolve blood vessels with diameters of 250 μm at depths of up to 2 cm. The vessel diameters derived on MSOT showed an excellent correlation (R2-score of 0.9426) with the vessel diameters on histopathology. Subsequently, we identify features of malignancy observable in MSOT, such as intranodular microvascularity and extrathyroidal extension verified by histopathology. Despite these promising features in selected patients, we could not determine statistically relevant differences between benign and malignant thyroid nodules based on mean oxygen saturation in thyroid nodules. Thus, we illustrate general imaging artifacts of the whole field of optoacoustic imaging that reduce image fidelity and distort spectral contrast, which impedes quantification of chromophore presence based on mean concentrations.

Conclusion
We recommend examining optoacoustic features in addition to chromophore quantification to rank malignancy risk. We present optoacoustic images of thyroid nodules with the highest spatial resolution and spectral contrast to date, directly correlated to histopathology, pushing the clinical translation of MSOT.
Good rates of return-to-sport in athletes after revision anterior cruciate ligament reconstruction using autologous patellar tendon and lateral extra-articular tenodesis: a 2-year follow-up prospective study

Abstract
Background
Most athletes who undergo revision of the anterior cruciate ligament reconstruction (ACLR) aim to return to their preinjury sport at a similar level of performance while minimizing the risk for reinjury. Additional lateral extra-articular tenodesis (LET) has recently been correlated with improved outcomes and low complication rate. Yet, there are few series evaluating return-to-sport (RTS) and clinical outcomes after revision ACLR using bone-patellar tendon-bone (BPTB) and LET in athletes.

Methods
The study cohort consisted of 19 eligible athletes who had undergone their first revision ACLR using BPTB and LET (modified Lemaire) between January 2019 and 2020. Patients were prospectively followed and interviewed in a sports activity survey during a 2-year follow-up.

Results
Despite all patients returning to sports after revision ACLR surgery, 52.6% resumed playing at their preinjury level. Furthermore, patient-reported functional outcomes improved significantly following revision surgery, as evidenced by improvements in IKDC [64.4 (± 12) to 87.8 (± 6)], Lysholm [71.27 (± 12) to 84.2 (± 9.7)], and SF-12 scales [Physical: 53.3 (± 3) 57 (± 1.2); Mental: 50.2 (± 3.3) to 52.7 (± 2.4)]. One case (5.3%) experienced persistent pain and underwent reoperation for a partial meniscectomy.

Conclusion
After revision ACLR using autologous BPTB and LET, all active individuals are expected to RTS, similar to primary ACLR. The difference comes down to returning to the preinjury level, where the levels are lower depending on the sport and initial level of play. Good mid-term functional outcomes with a low complication rate can be expected in most cases.

Katsarosite Zn(C2O4)·2H2O, a new humboldtine-group mineral from the Lavrion Mining District, Greece
Authors: Giester Gerald , Rieck Branko , Lengauer Christian L. , Kolitsch Uwe , Nasdala Lutz 
Published: April 2023

AbstractKatsarosite, ideally Zn(C2O4)·2H2O, named for Īraklīs Katsaros, is a new mineral found at the Esperanza Mine in the Kaminiza area of the Lavrion Mining District, Greece. Katsarosite usually occurs directly on sphalerite or embedded in jarosite and/or hydrozincite, often intimately intergrown with gypsum and overgrown by goslarite and/or epsomite. Crystal aggregates are mostly fine granular to earthy, with individual crystals being usually rounded with an average diameter of 30 µm, sometimes prismatic along [001] or platy, exhibiting the indistinct forms {100}, {001}, {110}, and {101}. Katsarosite is malleable with a Mohs hardness of 1½ – 2 and exhibits a perfect cleavage on {110}; the fracture is uneven in all other directions. The colour depends on the iron (Fe2+) content, ranging from pure white in almost Fe-free samples to yellow in Fe-rich specimens. It has a resinous luster and a white streak; no luminescence has been observed under either short- or long-wave ultraviolet radiation. Katsarosite is optically biaxial (+). Refractive indices measured at a wavelength of 589 nm are nα = 1.488(2), nβ = 1.550(2), nγ = 1.684(2), with 2Vobs = 71(3)°. Chemical analysis gave on average C2O3 38.32 wt%, ZnO 38.99 wt%, FeO 1.92 wt%, and H2O 19.04 wt% (the latter was deduced based on the crystal-structure refinement), with traces of MgO and MnO. The new mineral is readily soluble in dilute acids. Katsarosite is monoclinic, space group C2/c, with unit-cell parameters a = 11.768(3), b = 5.3882(12), c = 9.804(2) Å, β = 127.045(8)°, V = 496.2(2) Å3 (Z = 4). The strongest lines in the Gandolfi X-ray powder pattern [dobs in Å, Iobs/I100, (hkl)] are: 4.6745, 100, (200); 4.7678, 94, (20$$\overline{2 }$$

); 2.7032, 4, (020). The crystal structure was refined based on single-crystal X-ray diffraction data to R(F) = 0.08. The observed mass density of 2.50(2) g cm−3 compares well with the calculated value (2.508 g cm−3). Katsarosite belongs to the humboldtine group, whose crystal-structure type is well described for both isotypic minerals and synthetic compounds in the literature. The atomic arrangement in Zn(C2O4)·2H2O is characterized by chains consisting of isolated ZnO6 octahedra which are alternately linked along [010] via oxalate anions. These chains are interconnected through hydrogen bonds only, with Ow···O (with Ow denoting the O atom of the H2O molecule) donor–acceptor distances of ~ 2.8 Å.
