Free fatty acids in sunflower oil soap stock progressed the sophorolipid production by Candida catenulata
Authors: Amiri Fariba , Habibi Alireza 
Published: June 2023

AbstractSophorolipids are a group of surface‐active glycolipid compounds that can be synthesized by several yeasts, especially the Candida genera. Soap stock is a by‐product of vegetable oils refinery that enriches mono‐unsaturated fatty acids, and its application is interesting as a low‐cost industrial residue in sophorolipid production. In this study, the sophorolipid production was evaluated by Candida catenulate KP324968, using sunflower oil soap stock and glucose as the hydrophobic and hydrophilic carbon sources, respectively. The results indicated the ratio of hydrophobic to a hydrophilic carbon source, initial pH, and type of nitrogen source had significant roles in the performance of the cells. The highest specific biomass growth rate was about 0.0447 ± 0.0013 h−1 and a sophorolipid production rate of 49.96 ± 0.33 mg L−1 h−1 was obtained at a soap stock‐to‐glucose ratio of 1, initial pH of 5.5, and temperature of 30°C. The addition of organic nitrogen sources such as yeast extract and urea obtained a higher sophorolipid production in comparison with ammonium nitrate and potassium nitrate as the mineral nitrogen sources. Usage of both yeast extract and urea increased the sophorolipid production rate by 4.4% and 6.9%, in comparison with separate usage of yeast extract and urea, respectively. The characterization of the sophorolipid confirmed an emulsification index of about 30 ± 2.9% for diesel‐in‐water and 50 ± 3.5% for sunflower oil‐in‐water systems. The critical micelle concentration was determined at 280 mg L−1. The produced sophorolipid at a concentration of 500 mg L−1 showed an antibacterial capacity about of 95.4 ± 1.1%, and 44.7 ± 0.8% against Bacillus subtilis (Gram‐positive) and Escherichia coli (Gram‐negative) bacteria, respectively.
New method of whiteness calibration of spectrophotometers
Authors: Brill Michael H. , Xu Zhiling 
Published: June 2023

AbstractA method is described for determining and calibrating the CIE Whiteness Index (WI) of an OBA‐treated specimen without incorporating into the measurement system a mechanically adjustable UV filter. The method requires spectrophotometric measurement of the specimen under two lights: UV‐excluded to infer the reflectance r(λ) and UV to infer the fluorescence profile f(λ). Also required is a stored illuminant spectrum Iin(λ) that covers at least the whole visible wavelengths. Only one scalar value k is then needed to mathematically characterize the total spectral radiance factor (TSRF) of the same specimen under Iin(λ). Calibration uses a reference specimen with known WI, and adjusts k until the computed WI matches the reference WI value. If Iin(λ) is the illuminant chosen from ASTM E313 to define the WI, the k adjustment reduces to solving a single quadratic equation for k that involves the reference WI. In general, relative to directly measuring a specimen's TSRF, it is more instrument‐independent to use the current method to characterize TSRF. Therefore, if a fluorescent specimen is measured using UV and UV‐excluded illuminants, a complete, instrument‐stable characterization of the specimen's TSRF can be derived by adjusting k, which can be done through a closed‐form relation of k to the WI.
Covalent Triazine Framework Films through In‐Situ Growth for Photocatalytic Hydrogen Evolution

Published: June 2023

AbstractPhotocatalytic hydrogen evolution through water splitting offers a promising way to convert solar energy into chemical energy. Covalent triazine frameworks (CTFs) are ideal photocatalysts owing to its exceptional in‐plane π‐conjugation, high chemical stability, and sturdy framework structure. However, CTF‐based photocatalysts are typically in powder form, which presents challenges in catalyst recycling and scale‐up applications. To overcome this limitation, we present a strategy for producing CTF films with excellent hydrogen evolution rate that are more suitable for large‐scale water splitting due to their ease of separation and recyclability. We developed a simple and robust technique for producing CTF films on glass substrates via in‐situ growth polycondensation, with thicknesses adjustable from 800 nm to 27 μm. These CTF films exhibit exceptional photocatalytic activity, with the hydrogen evolution reaction (HER) performance reaching as high as 77.8 mmol h−1 g−1 and 213.3 mmol m−2 h−1 with co‐catalyst Pt under visible light (≥420 nm). Additionally, they demonstrate good stability and recyclability, further highlighting their potential in green energy conversion and photocatalytic devices. Overall, our work presents a promising approach for producing CTF films suitable for a range of applications and paves the way for further developments in this field.
A quasi‐two‐switch power factor correction converter for on‐board battery chargers

Published: June 2023

SummaryThis paper describes a quasi‐two‐switch buck‐boost power factor correction (PFC) converter for use in on‐board battery chargers to create a variable output voltage that is less than or greater than the peak input voltage. A two‐stage converter links the input grid power to the battery pack both in battery‐operated electric cars (BEVs) and plug‐in hybrid electric vehicles (PHEVs), with battery pack voltages ranging from 100 to 500 V depending on vehicle size and capacity. A universal charger that can manage such a wide range of battery pack voltages is appropriate for all vehicle designs. This requirement is met by supplying a changeable DC link voltage at the input of the DC/DC converter, which is a major obstacle in battery chargers when it comes to achieving universal output voltages. The major contribution of this research is the analysis and design of a dual‐control technique for a cascaded buck‐boost converter suited for a power factor correction (PFC) rectifier. The control loop is designed to allow a seamless transition from buck‐boost operation while putting less stress on the devices. The converter's power loss and small‐signal model are also investigated. From an economic standpoint, this concept allows the automobile industry to manufacture a single power converter, which is flexible and capable of charging numerous vehicle variants. Results have been verified both with a PSIM (11.0) simulation model and an experimental setup for a 1‐kW PFC converter suitable for universal input voltages of 85–265 Vrms and broad output voltages.
Turtle body size evolution is determined by lineage‐specific specializations rather than global trends

Published: June 2023

AbstractOrganisms display a considerable variety of body sizes and shapes, and macroevolutionary investigations help to understand the evolutionary dynamics behind such variations. Turtles (Testudinata) show great body size disparity, especially when their rich fossil record is accounted for. We explored body size evolution in turtles, testing which factors might influence the observed patterns and evaluating the existence of long‐term directional trends. We constructed the most comprehensive body size dataset for the group to date, tested for correlation with paleotemperature, estimated ancestral body sizes, and performed macroevolutionary model‐fitting analyses. We found no evidence for directional body size evolution, even when using very flexible models, thereby rejecting the occurrence of Cope's rule. We also found no significant effect of paleotemperature on overall through‐time body size patterns. In contrast, we found a significant influence of habitat preference on turtle body size. Freshwater turtles display a rather homogeneous body size distribution through time. In contrast, terrestrial and marine turtles show more pronounced variation, with terrestrial forms being restricted to larger body sizes, up to the origin of testudinids in the Cenozoic, and marine turtles undergoing a reduction in body size disparity after the extinctions of many groups in the mid‐Cenozoic. Our results, therefore, suggest that long‐term, generalized patterns are probably explained by factors specific to certain groups and related at least partly to habitat use.

AbstractAimsThe purpose of this study is to assess the efficacy of prophylactic negative pressure wound therapy (NPWT) in obese women undergoing caesarean section.DesignAn updated review and meta‐analysis of randomized controlled trials following Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines.MethodsPubMed, Embase, Medline, Web of Science, and Cochrane Library were searched from inception up to March 2022 without restriction in language. We chose surgical site infection as the primary outcome.ResultsNPWT resulted in a lower surgical site infection rate compared with conventional dressing (risk ratio [RR] = 0.76). The infection rate after low transverse incision was lower comparing the NPWT group with the control group ([RR] = 0.76). No statistically significant difference was detected in blistering([RR] = 2.91). The trial sequential analysis did not support the 20% relative decrease in surgical site infection in the NPWT group.

AbstractAimThis phase 1 study assessed the pharmacokinetics, safety, and tolerability of zuranolone in Japanese and White healthy adults, and Japanese healthy elderly subjects.MethodsThis single‐center study consisted of three parts. In Part A (randomized, double‐blind), the safety, tolerability, and pharmacokinetics of single dose and 7‐day consecutive multiple doses of zuranolone 10, 20, and 30 mg and placebo were assessed in 36 Japanese adults, 24 White adults, and 12 Japanese elderly (aged 65–75 years) subjects. In Part B (randomized, open‐label, crossover), the effect of food intake on the pharmacokinetics and safety of single‐dose zuranolone 30 mg was evaluated in 12 Japanese adults. In Part C (randomized, double‐blind, crossover), the effects of single‐dose zuranolone 10 and 30 mg and placebo on electroencephalography parameters were evaluated in eight Japanese adults.ResultsSingle and multiple doses of zuranolone were safe and well tolerated in all subjects. Linear pharmacokinetics were observed in the studied dose range. Time to steady‐state plasma concentration was within 72 h for Japanese and White adults. Pharmacokinetic profiles were comparable between Japanese and White adults and between Japanese adults and Japanese elderly subjects. Plasma exposures of zuranolone were greater in the fed versus fasted state. Single‐dose zuranolone 30 mg increased low‐beta electroencephalography power.ConclusionIn healthy Japanese subjects, zuranolone was well tolerated; pharmacokinetic profile was unaffected by ethnicity or age; plasma exposures were greater in the fed state. The increased low‐beta electroencephalography power with the 30‐mg dose is consistent with γ‐aminobutyric acid receptor type A activation by zuranolone.

Published: June 2023

AbstractIn this study, a promising modified composite scaffold (hydroxyapatite/hyperbranched polyitaconic acid/chitosan) was synthesized for bone tissue engineering. Novel hyperbranched polyitaconic acid was prepared through the polymerization of itaconic acid using reversible addition fragmentation chain transfer using a macro‐RAFT agent. The chemical structure of the prepared hyperbranched polyitaconic acid was characterized by FTIR and 1HNMR and was subsequently embedded into hydroxyapatite/chitosan composite. The obtained modified composite scaffold was evaluated by characterizing its porosity, mechanical properties, bioactivity and cytotoxicity. The results showed that the modified composite scaffold had higher mechanical strength (i.e., 0.56 ± 0.03 MPa) in comparison to chitosan/hydroxyapatite scaffold only (i.e., 0.31 ± 0.01 MPa) and also showed higher bioactivity. In addition, the modified composite scaffold (HAP/HBP‐RAFT‐PI/CS) showed anticancer properties and enhanced human skin fibroblasts proliferation.

Published: June 2023

AbstractBACKGROUNDThe Asian longhorned tick, Haemaphysalis longicornis, continues to expand its range in North America, and synthetic acaricides are likely to play an increasing role in managing this species. Acaricide resistance is common in some tick species that infest livestock. However, baseline acaricide susceptibility has not previously been examined in this invasive tick.RESULTSWe used a standard larval packet test to evaluate the susceptibility of the Asian longhorned tick to acaricides currently or formerly used in tick control: propoxur, carbaryl, bifenthrin, permethrin, and coumaphos. Discriminating concentrations were estimated at 6.5, 27.9, 988, 2242, and 808 ppm, respectively. The half‐maximal lethal concentration (LC50) values for propoxur, carbaryl, permethrin and coumaphos were compared with data available for other tick species and showed that H. longicornis was more susceptible to propoxur, carbaryl and coumaphos, and had a similar susceptibility to permethrin.CONCLUSIONSThe results indicate that resistance to these acaricides is not currently a concern for H. longicornis in the United States. However, responsible integrated management and early detection of resistance can help ensure the long‐term efficacy of products used for controlling this tick species. © 2023 The Authors.

Published: June 2023

AbstractGulf of Eilat is rich with energy resources, however any industrial natural resource development requires additional safety, as local eco‐system has to be preserved. In contrast to bivariate reliability approaches, known to their accurate predictions of extreme response and load levels for two‐dimensional dynamic systems, this study suggests and validates novel structural reliability method, which is being appropriate method for high‐dimensional dynamic systems. Conventional reliability methods do not have an advantage of dealing easily with high‐dimensional nonlinear dynamic systems, especially with non‐linear cross‐correlations between different system components. Advocated approach does not have limitations on the system's number of degrees of freedom, and it can accurately assess dynamic system's failure risks. Main purpose of this study was to benchmark state‐of‐the‐art reliability methodology, while utilizing available dataset efficiently. Note that advocated approach is not limited to offshore engineering example, studied here, and it has wide range of potential engineering and design applications.
Residential photovoltaic and energy storage systems for sustainable development: An economic analysis applied to incentive mechanisms
Authors: D'Adamo Idiano , Dell'Aguzzo Alessandro , Pruckner Marco 
Published: June 2023

AbstractThe photovoltaic (PV) system has a very significant growing global trend and its role is essential in combating climate change. However, its intermittent nature requires integration with a battery energy storage system (BES). This work proposes an economic analysis based on net present value (NPV) for an integrated PV + BES system in a mature market (Italy). The analyses are applied to different policy (used for both PV and BES) and market (purchase price, selling price) contexts. Results show that the NPV(PV) ranges from 1061 to 7426 €/kW. The work identifies the conditions under which BES is affordable. The required increase in self‐consumption varies in the 14%–35% range. The purchase price and the percentage of energy‐self‐consumption play a crucial role in the profitability assessment of a PV + BES system. Incentive policies based on subsidized tax deductions and subsidies for energy produced and self‐consumed can enable a more sustainable energy future in the residential sector. This work suggests a mix of policy choices: (i) a subsidized tax deduction larger than 50% and a bonus for energy produced and self‐consumed for PV plants; (ii) subsidized tax deduction also for BESs but at a lower value than for PV plants; and (iii) encouraging a recycling industry.
A Coupled 3d Morphological Reconstruction Approach for Surface Microcrack in Si3n4 Ceramic Bearing Roller Based on Adaptive Nano Feature Extraction & Multiscale Depth Fusion

Published: June 2023

AbstractTo extract the fuzzy contour features, tiny depth features of surface microcracks in the Si3N4 ceramic bearings roller. An adaptive nano feature extraction and multiscale deep fusion coupling method is proposed, to sufficiently reconstruct the three‐dimensional morphology characteristics of surface microcracks. Construct an adaptive nano feature extraction method, form the surface microcrack image scale space and the Gaussian difference pyramid function equation, realize the detection and matching of global feature points. The sparse point cloud is obtained. Through polar‐line correction, depth estimation, and fusion of feature points on the surface microcracks image, a multiscale depth fusion matching cost pixel function is established to realize a dense point cloud reconstruction of surface microcracks. The reconstruction results show that the highest value of the local convex surface reconstructed by the dense point cloud reaches 1183 nm, and the lowest local concave surface is accurate to 296 nm. Compared with the measurement results of the confocal platform, the relative error of the reconstruction result is 24.6%. The overall feature‐matching rate of the reconstruction reaches 93.3%. It provides a theoretical basis for the study of surface microcrack propagation mechanism and the prediction of bearing life.

Published: June 2023

AbstractWe examine an emerging market multinational company's (EMNC's) transformation from an original equipment manufacturer (OEM) to an original brand manufacturer (OBM) and global leader. Our longitudinal study of Hisense—China's largest TV company (and the world's third largest) spans three decades and involves detailed interviews with over 50 executives. We study how the company's global value chain network evolved, how it reconfigured its organization, upgraded its capabilities, and enhanced its brand reputation. We develop propositions that may contribute to improved explanations for an EMNC's internationalization sequence, development of competitive advantages, overseas management practices, and brand building.

Abstract
Purpose
Information about the cost-effectiveness of a certain treatment is relevant for decision-making and healthcare providers. This study compares the cost-effectiveness of the novel Woven Endobridge (WEB) for intracranial aneurysm treatment with conventional coiling and stent-assisted coiling (SAC) from the perspective of the German Statutory Health Insurance.

Methods
A patient-level simulation was constructed to simulate 55-year-old patients with an unruptured middle cerebral artery aneurysm (size: 3–11 mm) considering WEB treatment, coiling or SAC in terms of morbidity, angiographic outcome, retreatment, procedural and rehabilitation costs and rupture rates. Incremental cost-effectiveness ratios (ICERs) were calculated as costs per quality-adjusted life years (QALYs) and costs per year with neurologic morbidity avoided. Uncertainty was explored with deterministic and probabilistic sensitivity analyses. The majority of data were obtained from prospective multi-center studies and meta-analyses of non-randomized studies.

Results
In the base case, lifetime QALYs were 13.24 for the WEB, 12.92 for SAC and 12.68 for coiling. Lifetime costs were 20,440 € for the WEB, 23,167 € for SAC, and 8200 € for coiling. Compared to coiling, the ICER for the WEB was 21,826 €/QALY, while SAC was absolutely dominated by WEB. Probabilistic sensitivity analysis revealed that at a willingness-to-pay of ≥ 30,000 €/QALY, WEB was the preferred treatment. Deterministic sampling showed that the discount rate, material costs and retreatment rates had the largest impact on the ICERs.

Conclusion
The novel WEB showed at least comparable cost-effectiveness to SAC for treatment of broad-based unruptured aneurysms. Considering all three modalities, coiling had the least costs; however this modality is often not appropriate for the treatment of wide-necked aneurysms.

AbstractThe present study tested the influence of stimuli emotional valence, emotional arousal, and typicality on memory recollection in three groups of participants exposed to the same environment through different modalities: in vivo exposure (i.e., real-life), 3D virtual reality (i.e., VR), and 2D pictures. Context-related free-recall, recognition accuracy, and recognition confidence were analyzed. The results showed that memory performance was best in the real-life modality, and participants in the VR and 2D pictures modalities performed comparably. Interesting effects of stimuli emotional valence and typicality emerged: in the VR and 2D pictures modalities, positive items were better recalled than negative items; typicality was relevant only in the real-life modality, with less common objects within the explored setting (i.e., an office) recalled more often. Furthermore, recognition accuracy and confidence were significantly higher in the real-life modality than in the VR and 2D pictures modalities. Further research is needed to support the creation of VR environments that are sufficiently comparable to real-life contexts in order to obtain higher ecological validity in studies of cognitive performance. In particular, the impact of stimuli typicality and emotional valence in VR contexts should be investigated to gain insight into how these features might improve memory recall in virtual scenarios.
