Published: September 2023

AbstractIn many arid and semi‐arid regions, such as Iran, traditional irrigation systems consume a large proportion of surface water and groundwater resources. In the last few decades, due to the undesirable effects of climate change and continuous drought, many studies have been conducted on reducing threatening factors using the capacity of irrigation and drainage networks and participating water users in irrigation management. This study aimed to evaluate the performance of the irrigation and drainage network of the Varamin Plain using the SWOT model that is an analytical model used based on the results of the strengths, weaknesses, opportunities and threats of the subject, considering the cooperative management of water users. In addition to conducting interviews, a questionnaire was used to collect data from two groups of network water users and experts. According to the results, the farmers and water users of the network are in a relatively good situation in terms of access to water, possibly due to the available three annual planting seasons (due to the existence of irrigation and the drainage network and the use of grey water, conditions for irrigation and crop cultivation are available in four seasons of the year). The most critical concerns of the water users were the lack of knowledge about the organization of water collectors, the inconsistency among governmental organizations and the insignificant action of the Agricultural Jihad Organization (a government ministry in Iran to advance agricultural goals and all related matters) in solving issues related to water rights. Failure to inform the users about the costs of creating network infrastructure, maintaining facilities and canals, not accepting water shortage conditions and the state of groundwater resources, consecutive cropping seasons throughout the year, cultivation of crops with high water demand, people with political and social influence obtaining excess water rights, and the lack of coordination among related governmental policies were the most critical concerns of the experts.

AbstractBackgroundDistillers' grain waste (DGW) is the main by‐product in the Baijiu‐making process and its management remains a great challenge for the Baijiu industry. To address this issue, an integrated biobutanol and biomethane production process was established to obtain valuable products from DGW and reduce environmental pollution.ResultsIn the integrated process, DGW was hydrolyzed and detoxified to produce biobutanol, while the distillery waste derived from solvent extraction process was used for biomethane fermentation. After the optimization of overliming detoxification of DGW hydrolysate by artificial neural network and genetic algorithm, totals of 10.65 ± 0.07 g L−1 butanol and 4.51 ± 0.21 g L−1 isopropanol were attained with negligible amounts of acetone and ethanol (i.e. 0.14 ± 0.00 and 0.52 ± 0.06 g L−1, respectively). Anaerobic digestion of the distillery waste was efficient, and the chemical oxygen demand removal rate approached 92.3 ± 0.1% with a methane yield of 167.8 ± 1.2 mL g−1 TCODremoved. Moreover, the anaerobic digestion effluent could be recycled as a potential substitute for process water in biobutanol fermentation without having any negative effect on enzymatic hydrolysis of DGW, and the butanol production also reached 8.19 ± 0.29 g L−1.ConclusionThe present study provides a new idea for comprehensive utilization of DGW towards energy and resource recovery, without secondary pollution. © 2023 Society of Chemical Industry.

要旨緊急でECMO導入が必要な場合，カニュレーションに伴う合併症を起こすことがある。症例は13歳の女児。急性心筋炎の疑いで，当院に転院した。転院後に無脈性心室頻脈となり，ECPRを開始した。右大腿動静脈から経皮的にカニューレの挿入を試みたが，挿入中にガイドワイヤが抜去困難となったため，左大腿動静脈にカットダウンにてカニューレを挿入しECMOを確立した。遺残したガイドワイヤは右鼠径部皮下で複雑なループを形成した後，血管内に入り，先端は上大静脈に到達していた。ガイドワイヤは牽引しても抜去できないため，出血性合併症のリスクを考慮し，待機時にガイドワイヤを抜去する方針とした。その後，心機能は改善し，入院8日目にECMOを離脱，ガイドワイヤの走行をCT検査で確認した後，入院11日目に外科的にガイドワイヤを除去した。とくに大きな合併症は認めず，ICUを退室した。ガイドワイヤ遺残などカニュレーションに伴う合併症が生じた場合，原疾患の病態および遺残したまま管理するリスクとECMO中の出血性合併症などのリスクを考慮し，安全に抜去できる時期と方法を考え抜去の戦略を立てることが重要である。

要旨　糖尿病の既往がある45歳の男性。メトホルミン40,000mgを含む過量内服で救急搬送された。来院時バイタルサインは，意識レベルGCS 14，血圧149/71mmHg，心拍数97bpm，SpO2 98%（室内気），呼吸数26/分であった。血液ガス分析では，pH 7.201，乳酸値13.6mmol/Lと重篤な乳酸アシドーシスを認め，2時間後にpH 7.131，乳酸値20.2mmol/Lと増悪したため血液浄化療法を開始した。その後，pH 7.029，乳酸値23.9mmol/Lまで増悪したが，透析流量を増加したところ改善し，第3病日にはpH 7.367，乳酸値1.9mmol/Lまで改善したため血液浄化療法を離脱し，第22病日にリハビリ転院となった。後日判明した来院時のメトホルミンの血中濃度は32.0μg/mLであった。メトホルミンは小分子であり透析で除去可能だが，中毒の際には分布容積が大きいことによる血中濃度の再上昇や循環不全による乳酸産生増大なども加わり乳酸アシドーシスが遷延すると考えられる。

AbstractMeasurements in seven sites in the Campus of the University of the Balearic Islands (UIB; Mallorca, Spain) during an experimental campaign to study the contribution of local surface heterogeneities on the surface energy budget at one point have been used to characterize the differences in extreme daily temperatures between the sites during a summer month. Absolute temperature differences in this month reached up to 1.92 (with a median of 0.73) and 2.02 (median of 1.21)°C for daily maximum and minimum, respectively. Higher differences in the minimum temperature can be attributed to the stably stratified and weak turbulent conditions at night that enhance local differences in the surface energy fluxes, especially in an area with strong variability of the surface characteristics like the UIB Campus. Instead, during daytime, maximum temperature differences are smoothed due to the convection and the horizontal advection due to the sea‐breeze. Two sites with longer records allowed to study the seasonal variations of these differences, which were substantially lower in the colder months. These results suggest that relocation of observatories, even at distances as short as 200 m, may introduce important inhomogeneities in the temperature series. Therefore, raw values of series from nearby stations should not be used to infill missing data in other series without adequate statistical adjustments.

ObjectivesTo explore neurofilament light chain (NfL) levels in leprotic neuropathy compared to controls, and to determine if the changes correlate with ultrasonographic nerve findings.MethodsIndividuals with leprosy with signs or symptoms suggestive of peripheral nerve involvement were recruited. They were evaluated by clinical examination, functional scores, laboratory assessments (including NfL), nerve conduction studies (NCS), and ultrasound. Ultrasound was conducted in bilateral median, ulnar, tibial, fibular, sural, and vagus nerves as well as cervical roots 5 and 6. Results were compared to age, sex, and body mass index matched healthy controls.ResultsA total of 320 nerves from 20 patients and 480 nerves from 30 controls were evaluated. NfL was significantly elevated in those with leprosy with a mean and standard deviation of 7.50 + 2.83 compared with 3.42 + 1.18 in controls (P < .001). Ultrasound showed focal enlargement of the nerves, particularly at entrapment sites. Additionally, there were noticeable changes in neural Doppler signal, echogenicity, and epineural thickness among the measured nerve sites. NfL levels in those with leprosy correlated closely with nerve cross‐sectional area at all sites (P < .05). Functional and clinical assessment scores correlated with NfL and sonographic cross‐sectional area as well (P ≤ .05).ConclusionsNfL is elevated in leprotic neuropathy. Ultrasound showed specific morphological changes in individuals with leprosy, and nerve enlargement correlated with NfL levels. Thus, both modalities may be useful for the diagnosis, prognosis, and disease monitoring in those with leprotic neuropathy, and further investigations are warranted.

AbstractThermally conductive polymeric composites are promising for heat management in microelectronic devices. This work presents a binary‐hybrid composite of boron nitride (BN) nanoparticles and micro‐diamond (D) fillers in an elastomeric polyurethane (PU) matrix which can be three‐ dimensionally printed to produce a highly flexible and self‐supporting structure. The research shows that a combination of 16.7 wt% BN and 16.7 wt% D results in a robust network within the polymer matrix to improve the tensile modulus more than nine times with respect to neat PU. Significantly, the hybrid matrix enhances the thermal conductivity by more than two times when compared to neat PU. The enhancement in mechanical, and thermal features make this three‐dimensional printable multiscale hybrid composite suitable for flexible and stretchable microelectronic applications.

Published: September 2023

AbstractBackgroundCurrently, determining procedural endpoints and treatment efficacy of vascular interventions is largely qualitative and relies on subjective visual assessment of digital subtraction angiography (DSA) images leading to large interobserver variabilities and poor reproducibility. Quantitative metrics such as the residual blood velocity in embolized vessel branches could help establish objective and reproducible endpoints. Recently, velocity quantification techniques based on a contrast enhanced X‐ray sequence such as qDSA and 4D DSA have been proposed. These techniques must be robust, and, to avoid radiation dose concerns, they should be compatible with low dose per frame image acquisition.PurposeTo develop and evaluate a technique for robust blood velocity quantification from low dose contrast enhanced X‐ray image sequences that leverages the oscillating signal created by pulsatile blood flow.MethodsThe proposed spatiotemporal frequency domain (STF) approach quantifies velocities from time attenuation maps (TAMs) representing the oscillating signal over time for all points along a vessel centerline. Due to the time it takes a contrast bolus to travel along the vessel centerline, the resulting TAM resembles a sheared sine wave. The shear angle is related to the velocity and can be determined in the spatiotemporal frequency domain after applying the 2D Fourier transform to the TAM. The approach was evaluated in a straight tube phantom using three different radiation dose levels and compared to ultrasound transit‐time‐based measurements. The STF velocity results were also compared to previously published approaches for the measurement of blood velocity from contrast enhanced X‐ray sequences including shifted least squared (SLS) and phase shift (PHS). Additionally, an in vivo porcine study (n = 8) was performed where increasing amounts of embolic particles were injected into a hepatic or splenic artery with intermittent velocity measurements after each injection to monitor the resulting reduction in velocity.ResultsAt the lowest evaluated dose level (average air kerma rate 1.3 mGy/s at the interventional reference point), the Pearson correlation between ultrasound and STF velocity measurements was . This was significantly higher () than corresponding correlation results between ultrasound and the previously published SLS and PHS approaches ( and , respectively). In the in vivo study, a reduction in velocity was observed in of cases after injection of 1 mL, after 3 mL, and after 4 mL of embolic particles.ConclusionsThe results show good agreement of the spatiotemporal frequency domain approach with ultrasound even in low dose per frame image sequences. Additionally, the in vivo study demonstrates the ability to monitor the physiological changes due to embolization. This could provide quantitative metrics during vascular procedures to establish objective and reproducible endpoints.

AbstractDespite improvements in chemical recycling, most post‐consumer plastics are still deposited in landfills where they pose a significant threat to ecological health. Herein we report a two‐stage method for chemically recycling poly(ethylene terephthalate) (PET) using terpenoids and waste sulfur to yield composites. In this method, post‐consumer PET (from beverage bottles) undergoes transesterification with a terpenoid alcohol (citronellol or geraniol) to yield low‐molecular PET oligomers. The terpene‐derived alkenes in these PET oligomer derivatives then served as reaction sites for inverse vulcanization with 90 wt% elemental sulfur to form composite CPS (using citronellol) or GPS (using geraniol). Composition, mechanical, thermal, and morphological properties were characterized by NMR spectroscopy, MALDI, FT‐IR spectroscopy, compressive and flexural strength analysis, TGA, DSC, elemental analysis, and SEM/EDX. The composites CPS (compressive strength = 5.20 MPa, flexural strength = 3.10 MPa) and GPS (compressive strength = 5.8 MPa, flexural strength = 2.77 MPa) showed mechanical strengths comparable to those of commercial bricks (classification C62 for general building). The approach delineated herein thus represents a method to chemically recycle waste plastic with industrial waste sulfur and plant‐derived terpenoids to yield composites having favorable properties comparable to existing building materials.
Oxygen‐Containing Anions Promote the Electrocatalytic Activity of Ni(OH)2/NiOOH for The Urea Oxidation
Authors: Fang Zhongying , Liang Xiaolong , Lu Lehui , Chen Wei 
Published: September 2023

AbstractThe electrocatalytic oxidation of urea (EOU) is an important half‐reaction in water splitting, urea fuel cells, and urea wastewater treatment. The anions of nickel‐based catalysts can be leached severely in the oxidation potential range. Therefore, the influence of anion on the electrocatalytic performance of Ni(OH)2/NiOOH for urea oxidation has not been systematically studied. The present experimental results show that the structure reconstruction of catalyst is a complicated process, specifically including deep penetration by alkaline electrolyte, leaching‐induced oxidation by phosphorus or sulfur anions, transformation or cracking of the original structure, and formation of an amorphous layer on the surface. The reconstructed NF‐NiPx‐R or NF‐NiSx‐R has a three‐layer core‐shell structure, with a nickel foam skeleton in the innermost layer, an amorphous NiPx or NiSx layer in the middle layer, the outermost layer of oxygen‐containing anion (POx or SOx) coordinated Ni(OH)2. In the prepared catalyst, the Ni(OH)2/NiOOH redox is the real catalytic species for the urea oxidation. It is found that the oxygen‐containing anion can enhance the catalytic performance of the Ni(OH)2/NiOOH redox, and POx anion has the best enhancing effect. It is found that the urea molecules are oxidized on the electrocatalyst surface mainly through an indirect pathway.

AbstractWe have applied our advanced computational and experimental methodologies to investigate the complex structure and binding mechanism of a modified Wilms' Tumor 1 (mWT1) protein epitope to the understudied Asian‐dominant allele HLA‐A*24:02 (HLA‐A24) in aqueous solution. We have applied our developed multicanonical molecular dynamics (McMD)‐based dynamic docking method to analyze the binding pathway and mechanism, which we verified by comparing the highest probability structures from simulation with our experimentally solved x‐ray crystal structure. Subsequent path sampling MD simulations elucidated the atomic details of the binding process and indicated that first an encounter complex is formed between the N‐terminal's positive charge of the 9‐residue mWT1 fragment peptide and a cluster of negative residues on the surface of HLA‐A24, with the major histocompatibility complex (MHC) molecule preferring a predominantly closed conformation. The peptide first binds to this closed MHC conformation, forming an encounter complex, after which the binding site opens due to increased entropy of the binding site, allowing the peptide to bind to form the native complex structure. Further sequence and structure analyses also suggest that although the peptide loading complex would help with stabilizing the MHC molecule, the binding depends in a large part on the intrinsic affinity between the MHC molecule and the antigen peptide. Finally, our computational tools and analyses can be of great benefit to study the binding mechanism of different MHC types to their antigens, where it could also be useful in the development of higher affinity variant peptides and for personalized medicine.
Tracking control by the Newton–Raphson method with output prediction and controller speedup

Published: September 2023

SummaryThis paper presents a control technique for output tracking of reference signals in continuous‐time dynamical systems. The technique is comprised of the following three elements: (i) a fluid‐flow version of the Newton–Raphson method for solving algebraic equations, (ii) a system‐output prediction which has to track the future reference signal, and (iii) a speedup of the control action for enhancing the tracker's accuracy and, in some cases, stabilizing the closed‐loop system. The technique can be suitable for linear and nonlinear systems, implementable by simple algorithms, and can track reference points as well as time‐dependent reference signals. Though inherently local, the tracking controller is proven to have a global convergence for a class of linear systems. The derived theoretical results of the paper include convergence of the tracking controller and error analysis, and are supported by illustrative simulation and laboratory experiments.

Abstract2D transition metal carbides and nitrides (MXenes) are actively pursued as pseudocapacitive materials for supercapacitors owing to their advantages in electronic conductivity and surface reactivity. Increasing the fraction of ─O terminal groups in Ti3C2Tx is a promising approach to improve the pseudocapacitive charge storage in H2SO4 electrolytes, but it suffers from a lack of effective functionalization methods and stability of the groups in practical operation. Here a low‐temperature and environment‐friendly approach via the interaction of nonequilibrium plasmas with Ti3C2Tx dispersion is demonstrated to generate abundant and stable surface‐terminating O groups. The impact of the discharge environment (Ar, O2, and H2) on the structural characteristics and electrochemical performance of Ti3C2Tx nanosheets is studied. The Ti3C2Tx modified in Ar and H2 maintains their original morphology but a significantly lower F content. Consequently, an extraordinarily high content (78.5%) of surface‐terminating O groups is revealed by the high‐resolution X‐ray photoelectron spectroscopy spectra for the Ti3C2Tx samples modified in H2 plasma‐treated solutions. Additionally, the Ti3C2Tx treated using H2 plasmas exhibits the best capacitive performance of 418.3 F g−1 at 2 mV s−1, which can maintain 95.88% capacity after 10 000 cycles. These results contribute to the development of advanced nanostructured pseudocapacitive electrode materials for renewable energy storage applications.
A micromorphological analysis ofBolonia lataMeunier from the Cretaceous of the Neuquén Basin (Patagonia, Argentina): new insights into the tracemaker

Published: September 2023

AbstractPolychaetes, echinoids and gastropods have been proposed as tracemakers forBoloniaMeunier, an elongate positive epirelief trace fossil characterized by two lobes composed of biserial, subtriangular pads and a mostly heart‐shaped cross‐section. Here, the internal structure and micromorphology ofBoloniaare described for the first time using serial thin sections from shallow‐marine Lower Cretaceous intervals of the Agrio Formation (Neuquén Basin, Argentina). In vertical thin sections, a conical structure of variable width extends centrally from the base to the top of the trace. In horizontal thin sections, grains are reoriented and reworked, forming a central zigzag structure. The organic matter and clays form grain aggregates representing the internal structure of individual pads of the trace fossil. The sediment has mostly been reoriented, with grains making up subcircular pods. We interpret the central conical structure as the collapse of the medial zone of the trace fossil, which could have destroyed drain tubes, especially in the absence of early cementation. Studying horizontal thin sections, we reconstruct the diagnostic biserial pads as biserial concave structures. These are interpreted as backfilling structures produced by the aboral and lateral spines of irregular echinoids, which worked together to compact the sediment anteroposteriorly and moved alternatively, explaining the zigzag pattern in the menisci. We propose Spatangoidea or Cassiduloidea (or a closely related group) with a similar burrowing ability and spine movement as tracemakers of theseBoloniaspecimens.
