Published: December 2023

The need for reliable analytical techniques for food quality control and fraud detection has notably increased in the last few decades. There are two main aspects that are of concern: adulteration and authentication. In particular, the introduction of quality labels such as the protected denomination of origin, organic food, mountain denomination, etc. poses more challenges, since these quality attributes and their assessment is necessarily linked to the foodstuff as a whole and requires a holistic approach to food characterization. Consequently, the preferred analytical techniques are those furnishing on the one hand a complete compositional profile, such as in foodomics, and on the other hand a quick-to-acquire but unique fingerprint, such as fast non-destructive spectroscopy or other food sensors. In this respect, chemometrics is fundamental to unravelling the distinctive food traits from these complex responses or to speed up the resolution and putative identification process in hyphenated chromatographic techniques. This chapter will revise the main and most recent trends, pointing out the most relevant issues.

Crime scene investigation relies heavily on evidence derived from biological materials like bodily fluids, tissues, hair, and fingermarks. It is possible to obtain a great deal of important information about the crime and the donor individuals from the biological materials. In recent years, vibrational spectroscopy has emerged as a rapid, non-destructive, label-free, and user-friendly technique for biological analysis. When it comes to forensic biological analysis, it is most frequently applied to bodily fluids. This chapter discusses recently published studies in which vibrational spectroscopy coupled with chemometric algorithms was employed for forensic bodily fluid investigation, such as identification of bodily fluids, determination of the donor’s species, estimation of the deposition time, and characterization of the donor’s basic information (e.g., age, sex, race). Problems encountered in applying these techniques to routine forensic practice and perspectives with regard to the further improvement of forensic bodily fluid spectral investigation techniques are also discussed in this chapter.
Environmental Forensics

Published: December 2023

Environmental forensics has emerged because relevant stakeholders can be compensated if contamination events or damages to the environment or health are committed, underpinned by legislative frameworks. The ability to prosecute based on environmental forensics requires rigorous record-keeping and data that is defendable in court and limited to data obtained from laboratories using standard accredited analytical methods, techniques, and instrumentation. The critical questions required to answer questions pertaining to the environment are typically associated with understanding the extent of the damage, the duration and residencies of the pollution, and the responsibilities of the environment based on the regulatory context. To answer environmental forensic problems, a number of variables are required to be known: chemical fingerprinting, fates of chemicals, transport modelling, hydrogeological and limnological surveys, operational legacy, and current or historical data, representing a highly multivariate issue. Multivariate being many variables, analytes of interest, matrices, and data associated with the problem at hand. We will discuss modern and emerging rapid-field deployable systems coupled with chemometrics, which can be translated to gaining information and chemical fingerprinting based on environmental contamination (e.g., metals, nanoplastics, oils, pesticides, perfluoralkanes), their identification, quantification, and source determination in a modern capacity using chemometrics and modern methods of statistical analysis to support environmental contamination applications.

Structural insights into ferroportin mediated iron transport
Authors: Jormakka Mika
Published: December 2023

Iron is a vital trace element for almost all organisms, and maintaining iron homeostasis is critical for human health. In mammals, the only known gatekeeper between intestinally absorbed iron and circulatory blood plasma is the membrane transporter ferroportin (Fpn). As such, dysfunction of Fpn or its regulation is a key driver of iron-related pathophysiology. This review focuses on discussing recent insights from high-resolution structural studies of the Fpn protein family. While these studies have unveiled crucial details of Fpn regulation and structural architecture, the associated functional studies have also at times provided conflicting data provoking more questions than answers. Here, we summarize key findings and illuminate important remaining questions and contradictions.
Cough: An Introductory Guide for Speech-Language Pathologists
Authors: Novaleski Carolyn K. , Near Lucille A. , Benzo Roberto P.
Published: December 2023

Purpose:

The airway defense mechanism of cough is essential for human survival. Recognition is growing about the distinct role of speech-language pathologists in the nonpharmacological management of various cough disorders. This clinical focus article aims to deliver relevant education about normal and pathological cough to strengthen existing clinical knowledge and skills.

Conclusions:

The neuronal pathways underlying normal cough function are complex. Cough problems refer to either reduced or heightened cough stemming from various disease processes, and both clinical presentations have detrimental consequences. Current evidence supports that patients who suffer from cough dysfunction benefit from nonpharmacological interventions offered via speech therapy as an adjunct to medical treatments. Speech therapy strategies apply the higher cognitive components of cough by focusing on the deliberate modification and coordination of respiration. Future research priorities are positioned toward improving clinical outcomes for cough disorders.
Influence of protostellar outflows on star and protoplanetary disk formation in a massive star-forming clump
Authors: Lebreuilly U. , Hennebelle P. , Maury A. , González M. , Traficante A. , Klessen R. , Testi L. , Molinari S.
Published: December 2023

Context. Due to the presence of magnetic fields, protostellar jets or outflows are a natural consequence of accretion onto protostars. They are expected to play an important role in star and protoplanetary disk formation.

Aims. We aim to determine the influence of outflows on star and protoplanetary disk formation in star-forming clumps.

Methods. Using RAMSES, we performed the first magnetohydrodynamics calculation of massive star-forming clumps with ambipolar diffusion; radiative transfer, including the radiative feedback of protostars; and protostellar outflows while systematically resolving the disk scales. We compared this simulation to a model without outflows.

Results. We found that protostellar outflows have a significant impact on both star and disk formation. They provide a significant amount of additional kinetic energy to the clump, with typical velocities of around a few 10 km s−1; impact the clump and disk temperatures; reduce the accretion rate onto the protostars; and enhance fragmentation in the filaments. We found that they promote a more numerous stellar population. They do not impact the low-mass end of the IMF much, which is probably controlled by the mass of the first Larson core; however, they have an influence on its peak and high-mass end.

Conclusions. Protostellar outflows appear to have a significant influence on both star and disk formation and should therefore be included in realistic simulations of star-forming environments.
Post-dynamical inspiral phase of common envelope evolution
Authors: Gagnier Damien , Pejcha Ondřej
Published: December 2023

During common envelope evolution, an initially weak magnetic field may undergo amplification by interacting with spiral density waves and turbulence generated in the stellar envelope by the inspiralling companion. Using 3D magnetohydrodynamical simulations on adaptively refined spherical grids with excised central regions, we studied the amplification of magnetic fields and their effect on the envelope structure, dynamics, and the orbital evolution of the binary during the post-dynamical inspiral phase. About 95% of magnetic energy amplification arises from magnetic field stretching, folding, and winding due to differential rotation and turbulence while compression against magnetic pressure accounts for the remaining ∼5%. Magnetic energy production peaks at a scale of 3ab, where ab is the semimajor axis of the central binary’s orbit. Because the magnetic energy production declines at large radial scales, the conditions are not favorable for the formation of magnetically collimated bipolar jet-like outflows unless they are generated on small scales near the individual cores, which we did not resolve. Magnetic fields have a negligible impact on binary orbit evolution, mean kinetic energy, and the disk-like morphology of angular momentum transport, but turbulent Maxwell stress can dominate Reynolds stress when accretion onto the central binary is allowed, leading to an α-disk parameter of ≃0.034. Finally, we discovered accretion streams arising from the stabilizing effect of the magnetic tension from the toroidal field about the orbital plane, which prevents overdensities from being destroyed by turbulence and enables them to accumulate mass and eventually migrate toward the binary.
Enhancing soil quality with coal fly ash amendment: a waste recycling approach for climate change mitigation in Indonesia - a review
Authors: Jubaedah  , Iskandar  , Baskoro Dwi Tejo P. , Mulyanto Budi , Nurida Neneng L.
Published: December 2023

Coal fly ash (CFA), a byproduct of coal combustion (CCP) from electric/thermal power plants, was classified as hazardous and toxic waste under Government Regulation Number 104/2014 in Indonesia. However, a significant shift in this regulatory viewpoint developed with the introduction of Government Regulation Number 22/2021. This regulation fundamentally altered the treatment and classification of CFA. Managing CFA as a waste has been both extensive and costly. In various countries where CFA is classified as non-hazardous and non-toxic waste, its utilization spans various sectors. Agriculture is a notable sector benefiting from CFA, as it is applied to soil amendment. As a soil amendment, CFA enhances nutrient availability and soil fertility, promotes plant development, and positively alters soil physical properties. In addition, CFA application to soil improves soil carbon storage, contributing to climate change mitigation and adaptation. This paper aims to review Indonesia's state of CFA utilization before the enactment of Government Regulation Number 22/2021, in order to present insights into the potential for expanded CFA utilization in soil amendment following the new regulation (Government Regulation Number 22/2021).

Published: December 2023

Climate change has an impact on plant growth, including mint. Mint grows optimally in environments with low temperatures and high humidity. Erratic climate change has the potential to reduce mint growth. Biochar is a soil enhancer that can improve soil fertility and soil water availability. Liquid Organic Fertilizer (LOF) is able to provide the nutrients needed by plants so that it has the potential to increase mint growth. This research was conducted in August 2022 - June 2023 in the greenhouse of the Agriculture's Faculty, Sebelas Maret University, Surakarta. The study used a factorial Randomized Complete Group Design (RCBD), which consisted of two factors, namely biochar and fish waste LOF. The types of biochar consisted of no biochar treatment, palm fiber biochar, and rice husk biochar. Fish waste LOF consisted of no LOF treatment, 5 ml/L water, 10 ml/L water, and P3 = 15 ml/L water. The results showed that the application of palm fiber biochar and 5 ml/L fish waste liquid fertilizer can increase plant fresh weight and plant dry weight. Giving palm fiber biochar can increase plant fresh weight, while the addition of rice husk biochar can increase leaf area and plant dry weight. This research has implications to knowing the interaction of biochar type and LOF concentration, getting the appropriate biochar type to increase mint growth, and getting the appropriate LOF concentration to increase mint growth. concentration that is suitable for increasing mint growth.

Published: December 2023

Whether investors take into account the company's information related to carbon emission mitigation and the company's environmental ranking in their investment decisions is an interesting research avenue. The objective of this study is twofold. First, it tests whether the level of carbon emissions disclosure differs by industry sector. Second, it examines whether carbon emission disclosures as reported by companies and their environmental performance affect the value of the firm. This study utilizes 102 companies in 2022 that are included in highly polluting industries as a sample, which is divided into 4 different sectors: consumer goods, energy, basic industry, and miscellaneous industry. The results of the analysis of variance (ANOVA) test reveal that the extent of carbon emissions reporting is different across industry sectors. Meanwhile, the multivariate regression results reveal that carbon emission disclosures positively influence the value of the firm. Environmental performance, however, does not impact firm value. This study informs the company's management that promoting higher levels of carbon emission mitigation and reporting would boost the company's reputation, which would in turn increase its value.

Authors: Istiyanti Eni , Wicaksono Gandhi Singgih
Published: December 2023

Tobacco is produced extensively in Indonesia, with the most excellent yields discovered in Temanggung Regency, located in Central Java. Climate change and increasing tobacco excise affect farmers' income. The study aims to determine the cost, profit, and feasibility of chopped tobacco farming after climate change and rising excise tax. This study involved 74 respondents, selected using simple random sampling, and utilized both primary and secondary data. The feasibility analysis employed the Revenue Cost Ratio (R/C) and Break Even Point (BEP) criteria. The results unveiled that chopped tobacco production was 773 kg/5,625 m2 or 1,374 kg/hectare and climate change had no effect on production. Chopped tobacco farming per growing season for five months required a total cost of IDR 37,013,965. a revenue of IDR 38,551,056, and a profit of IDR 1,537,091. Climate change and rising excise tax on chopped tobacco farming could reduce profits. However, following the R/C and BEP criteria, chopped tobacco farming was feasible.

Published: December 2023

Coastal land can be used by farmers to cultivate plants, including red chilies. Global climate change can affect the productivity of coastal land through changes in temperature so that production of red chilies is disrupted as a result, the supply of red chilies in the market is unstable. Therefore, this research was conducted with aim of describing the red chili supply chain and analyzing the performance of red chili supply chain produced from the cultivation of coastal land in terms of product flow, money flow, and information flow. The location of this research is coastal land in Bantul which was chosen deliberately because it is the highest area for red chili production in coastal land. Sampling of farmers in this study was carried out in stages from district to village level totaling 75 farmers from Manunggal farmer group. Sampling after farmers used snowball sampling technique, so that a total sample of 144 respondents consisted of 75 farmers, 1 auction market, 5 collectors, 21 retailers, and 42 household end consumers. Data analysis was carried out by describing the shape of image for red chili supply chain. Red chili supply chain performance was analyzed using scores and categories for product flow, cash flow, and information flow. The results of analysis show that supply chain of red chili cultivated on coastal land consists of three chains, namely (1) farmer-Manunggal auction market-collector I- retailer I-end consumer; (2) farmer-collector II-retailer II-end consumer; and (3) farmer- collector III-retailer III-end consumer. The best red chili supply chain performance is chain 2. The results of this study can be used as a source of information to choose the best performing supply chain.

Community forests can help to mitigate and adapt to climate change by storing carbon and providing ecosystem service. Non-Wood Forest Products (NWFPs) can serve as an adaptation strategy for forest-dependent communities in dealing with climate change. In addition, the availability of food and sources of income can be fulfilled by the existence of NWFPs. Given the significant role of NWFPs in climate change adaptation, this study was conducted to identify the types of NWFPs, evaluate their economic value, and determine their contribution to household income in Plosorejo Village. The data collection method used in the present study was field inventory and interviews with 30 respondents. Based on the obtained results in this study, 26 species of NWFPs developed in the community forest of Plosorejo Village, generate an economic value of 923.2 Million Rupiah per year. The commodity that gave the highest contribution to the economic value of NWFPs was durian, with a value of 630 Million Rupiah per year or 68.24% of the total economic value of NWFPs. The average contribution of the economic value of NWFPs to household income was 58.94%. Educational background and the area of community forest owned show a significant effect on the community income from NWFPs.

Authors: Gouaamar Radouan , Bri Seddik , Mekrini Zineb
Published: December 2023

This article presents a comprehensive analysis of the modeling and control techniques applied to a photovoltaic (PV) system that is connected to a three-phase grid. To successfully integrate the PV system with the electrical grid, an innovative and reliable controller has been designed and put into practice. The utilization of an artificial neural network (ANN) enables the system to optimize power extraction from the PV panels, benefiting from the ANN's resilience and swift response to varying conditions. Moreover, a robust proportional-integral (PI) control strategy is introduced to govern the grid-side operations. This strategy of action focuses on managing the injection of both active and reactive electricity into the grid as well as controlling the voltage of the DC bus. A series of detailed simulations were carried out evaluating the efficiency of the suggested control strategy in the MATLAB/SIMULINK. The results obtained from these simulations share insightful information on the effectiveness and efficiency of the control system in ensuring optimal operation and power management of the PV system within the grid-connected setup.

Indoor Radon and Thoron Measurement using CR-39 and LR-115 detectors in dwellings of Beni Mellal-Khenifra area (Morocco)
Authors: Kayouh Noura , Rabi Rabi , Oufni Lhoucine
Published: December 2023

Radon and thoron are radioactive gases that are found naturally in the environment. They can seep into homes through cracks in the foundation, walls, and floors. Once inside, they can build up to levels that are harmful to human health.

A study of radon and thoron concentrations in 65 homes in the Beni Mellal province of Morocco found that the levels varied widely, from 16 to 304 Bq.m-3 for radon and from 1 to 25 Bq.m-3 for thoron. The concentrations were found to be influenced by a number of factors, including the type of home, ventilation conditions, and the geological materials in the area. The average estimated dose received by the public due to radon and thoron in the homes studied was 45 ± 0.28 mSv.y-1 and 0.20 ± 0.01 mSv.y-1, respectively. These doses are considered to be low-level radiation exposure, but they can increase the risk of cancer over time. These results suggest that it would be beneficial to prohibit the construction of houses near industrial areas and to use construction materials that are adapted to the criteria of dose limitation.

Published: December 2023

The primary objective of this study was to assess the variation in the elemental composition of Cannabis Sativa seeds cultivated in Northern Morocco and to evaluate potential health risks associated with heavy metals (Cr, Cd, Pb, Ni, and As). We employed Inductively Coupled Plasma–Mass Spectrometry (ICP-MS) to identify and quantify both macro and trace elements in three seed samples. Our analysis revealed the presence of 20 elements in Cannabis seeds, with Mg, K, Ca, P, and Na present in substantial concentrations, while Cr, Zn, Fe, and other toxic elements were detected in trace amounts. Estimations of daily intake (EDI) indicated that Cr had the highest intake, followed by Ni, Pb, As, and Cd. However, Target Hazard Quotients (THQs) for individual metals and the Hazard Index (HI) all remained below 1, suggesting a relatively low risk associated with the consumption of Cannabis Sativa seeds from Northern Morocco. Furthermore, Carcinogenic Risk (CR) values were found to be at a tolerable level. In conclusion, our results suggest that the consumption of Cannabis Sativa seeds from this region poses minimal health risks."

Prenatal Detection and Postnatal Outcome of Persistent Left Superior
Vena Cava and Agenesis of Ductus Venosus Associated with Postnatal Bovine Aortic
Arch
Authors: Elbistanli Ceylin , Yozgat Yılmaz , Dogan Mehmet Said , Yozgat Can Yilmaz , Kütük Mehmet Serdar
Published: December 2023

Background Isolated agenesis of ductus venosus (ADV) is usually a benign
condition, but it may be associated with cardiovascular defects, hydrops, growth
restriction, and chromosomal abnormalities. Additionally, persistent left
superior vena cava (PLSVC) and bovine aortic arch are relatively common fetal
anomalies. To the author’s knowledge, this is the first report of
prenatal detection of DV agenesis and PLSVC associated with the postnatal bovine
aortic arch with a hypoplastic transverse aortic arch.

Case A 25-year-old, G2P1 woman was referred to our department at 31 weeks
due to fetal growth restriction and short femur. On fetal echocardiography, DV
could not be viewed via two-dimensional (2D) and Doppler ultrasound (US)
imaging; there was also evidence of the co-occurrence of PLSVC and an aortic
arch anomaly. We revealed the intrahepatic continuation of the umbilical vein. A
weekly follow-up program was scheduled for the patient and the rest of the
pregnancy was uneventful. Postnatal, thorax computer tomography and
transthoracic echocardiography (TTE) demonstrated PLSVC and bovine aortic arch
associated with hypoplastic transverse aortic arch. Routine echocardiographic
examinations revealed that the blood flow of the aortic arch had increased
gradually, and the male infant’s aortic arch had significantly widened
and reached the normal range until the baby was discharged from the
hospital.

Conclusion DV agenesis and PLSVC are usually benign conditions but
underlying serious heart diseases may accompany them. Therefore, in situations
like ours, a prenatal aortic arch evaluation is of capital importance. Postnatal
hemodynamic changes should be taken into consideration in the management of
these cases. This is the first example in the literature that these
abnormalities co-existed in one case.

Published: December 2023

Aim Inpatient rehabilitation plays an important role in treating neurological diseases in children and adolescents. However, there is a lack of current research concerning this matter. This retrospective study aims to analyze the effectiveness of neuropediatric inpatient rehabilitation, to identify influencing factors, and to examine the importance of inpatient rehabilitation programs.

Methods We reviewed medical records of patients, diagnosed with cerebral palsy, traumatic brain injury (TBI), or stroke who had an inpatient rehabilitation at the Department of Neuropediatrics of St. Mauritius Therapieklinik in Meerbusch from 2012 to 2019. The patients received several units of different therapies such as motor and cognitive rehabilitation or speech therapy per day, depending on their individual needs and aims. Rehabilitation outcome was assessed by comparing Gross Motor Function Measure-88 and Pediatric Evaluation of Disability Inventory admission and discharge scores. Influences of sex, age, length of stay (LOS), and admission score were analyzed.

Results A total of 738 patients with a mean age of 9.2 (± 5.1) years and a mean LOS of 53.8 (± 33.7) days were included; 38.5% were female. Patients, regardless of their diagnosis, sex, or age, demonstrated highly significant and meaningful improvements of self-care, mobility, and social function during inpatient rehabilitation. Especially, the group of patients with TBI and stroke could approximate their skills substantially to the ones of healthy peers. A longer LOS correlated significantly with greater improvement of skills.

Interpretation This is a current study, supporting the effectiveness of neuropediatric inpatient rehabilitation and affirming its value in treating neurological diseases in children and adolescents.

Specifically, we examine the role of home-country pro-market reforms in facilitating SOEs’ entry into host countries with a free-market logic. We consider two types of home-country pro-market reforms: market liberalization and privatization. We propose that home market liberalization mainly mitigates SOEs’ market legitimacy deficit and facilitates their entry into host countries with a prominent free-market logic. In such contexts, businesses perceive SOEs from more liberalized home markets as more accustomed to market competition and thus are less likely to exert pressure on the host government against them. We also argue that furthering SOEs’ privatization mitigates SOEs’ political legitimacy deficit in host countries with a free-market logic, thus facilitating entry. In these contexts, host governments perceive more privatized SOEs as more independent from their home state due to reduced political connections. We find support for our arguments in a dataset of 97 telecom SOEs from 97 countries over the period 1990–2010. Our study advances research on SOEs’ internationalization and research on pro-market reforms and has relevant implications for managers and policymakers.

Published: December 2023

This study aims to analyze the impact of consumption values on the adoption of NBG’s mobile banking services and the role of customers’ motivation and app adoption in this process. The study reveals users’ attitudes and behavior towards mobile banking by establishing significant connections between selected UTAUT constructs. Based on a critical case of the m-banking services of a leading Greek financial institution, we gathered 418 full-answered questionnaires from a convenience sample of 654 customers to test 18 research hypotheses. The research results confirm that the three selected UTAUT constructs, are antecedents of behavioral intention, supporting the initial assumption. This study analyzes the factors that drive the adoption and usage of mobile banking apps, providing valuable insights for marketing academia and managers.

Herein, a method of true-temperature inversion for a multi-wavelength pyrometer based on fractional-order particle-swarm optimization is proposed for difficult inversion problems with unknown emissivity. Fractional-order calculus has the inherent advantage of easily jumping out of local extreme values; here, it is introduced into the particle-swarm algorithm to invert the true temperature. An improved adaptive-adjustment mechanism is applied to automatically adjust the current velocity order of the particles and update their velocity and position values, increasing the accuracy of the true temperature values. The results of simulations using the proposed algorithm were compared with three algorithms using typical emissivity models: the internal penalty function algorithm, the optimization function (fmincon) algorithm, and the conventional particle-swarm optimization algorithm. The results show that the proposed algorithm has good accuracy for true-temperature inversion. Actual experimental results from a rocket-motor plume were used to demonstrate that the true-temperature inversion results of this algorithm are in good agreement with the theoretical true-temperature values.

The utilization of a low-frequency (<200 MHz) RF system in storage facilitates the attainment of ultra-low emittances in synchrotron light sources through on-axis injection. This paper focuses on the development of a low-frequency normal conducting (NC) cavity with higher-order mode (HOM) damping for fourth-generation synchrotron light sources. We propose a novel approach to achieve efficient HOM damping in a NC cavity by optimizing the lowest frequency HOM and implementing a beam-line absorber. Notably, unlike conventional NC cavities, the presence of a large beam tube for the beam-line absorber does not compromise the accelerating performance in a coaxial resonant cavity, enabling effective HOM damping while maintaining a high shunt impedance. Through simulations, the prototype design of a 166.6 MHz HOM-damped cavity demonstrates a fundamental mode impedance of ∼8 MΩ, with longitudinal and transverse HOM impedances below 2.0 and 50 kΩ/m, respectively.

The biological reduction of N2 to ammonia requires the ATP-dependent, sequential delivery of electrons from the Fe protein to the MoFe protein of nitrogenase. It has been demonstrated that CdS nanocrystals can replace the Fe protein to deliver photoexcited electrons to the MoFe protein. Herein, light-activated electron delivery within the CdS:MoFe protein complex was achieved in the frozen state, revealing that all the electron paramagnetic resonance (EPR) active E-state intermediates in the catalytic cycle can be trapped and characterized by EPR spectroscopy. Prior to illumination, the CdS:MoFe protein complex EPR spectrum was composed of a S = 3/2 rhombic signal (g = 4.33, 3.63, and 2.01) consistent with the FeMo-cofactor in the resting state, E0. Illumination for sequential 1-h periods at 233 K under 1 atm of N2 led to a cumulative attenuation of E0 by 75%. This coincided with the appearance of S = 3/2 and S = 1/2 signals assigned to two-electron (E2) and four-electron (E4) reduced states of the FeMo-cofactor, together with additional S = 1/2 signals consistent with the formation of E6 and E8 states. Simulations of EPR spectra allowed quantification of the different E-state populations, along with mapping of these populations onto the Lowe–Thorneley kinetic scheme. The outcome of this work demonstrates that the photochemical delivery of electrons to the MoFe protein can be used to populate all of the EPR active E-state intermediates of the nitrogenase MoFe protein cycle.
Different effects of suprathermal electrons and ions on drift instabilities in non-uniform plasmas
Authors: Guo Ran
Published: December 2023

The paper studies the drift instability in Kappa-distributed inhomogeneous plasmas. Weak inhomogeneity and local approximation are assumed. The linear dispersion relation is expressed in a novel integral representation that involves the standard plasma dispersion functions defined in Maxwellian plasmas rather than the generalized plasma dispersion function modified by the Kappa distribution. The analytical solutions of wave frequency and growth rate are derived when the wave speed is larger than the ion thermal speed but smaller than the electron thermal speed. The unstable drift mode is found to have a lower limit of wavenumber due to the suprathermal electrons, which does not exist in Maxwellian plasmas. The population of suprathermal ions affects the critical wavenumber for instability but does not determine its emergence. Moreover, the wave frequency, growth rate, and critical wavenumber are numerically solved from the dispersion relation. The results suggest that the critical wavenumber cannot be neglected with the typical parameters of space plasmas.

Published: December 2023

The effect of pulse-modulated sub-RF range (100 kHz–1 MHz) excitation on atmospheric pressure argon plasma jet characteristics is studied. For this, a suitable power supply is developed, offering a sub-µs rise time with control of different parameters, such as voltage amplitude, pulse modulation frequency in the range of 1–30 kHz, and an oscillation frequency of ∼520 kHz, which can affect the plasma behavior. Plasma characteristics, such as reactive species generation, ionic composition, plasma plume length, and gas temperature, are evaluated qualitatively and quantitatively by employing diagnostics such as optical emission spectroscopy, molecular beam mass spectrometry, and optical imaging. Experimental observations indicate that the gas temperature of the plasma jet and plume length increase with the applied voltage for all pulse modulation frequencies, with a maximum value of ∼(325 ± 2 K) and a maximum length of ∼(23 ± 3 mm), respectively, at 30 kHz and 9 kVpp. The emission intensities of OH• and O• lines show an incremental behavior with the applied voltage across all pulse modulation frequencies. The relative yield of different positive (OH+, O+, etc.) and negative (OH−, O−, etc.) ions also increases with the applied voltage for all pulse modulation frequencies with maximum values of ∼(7.6%, 9.9%) and (3.9%, 9.4%), respectively; these are relatively close to RF excited ionic concentrations reported previously. Attaining a high plasma length and species yield signify the features of both kHz and RF atmospheric plasmas. This study offers significant insights and flexibility into exploring the impact of different RF frequency regimes on plasma characteristics.
Similarity laws for two-dimensional simulations of low-pressure capacitively coupled radio-frequency discharges

Published: December 2023

Similarity laws (SLs) for low-pressure capacitive radio-frequency plasmas are generalized from one- to two-dimensional (2D) frameworks based on kinetic particle-in-cell simulations. Fundamental discharge parameters, such as the 2D distributions of electron densities and electric fields, are examined to assess the applicability of SLs to such discharges. The discharge characteristics are found to remain invariant when external control parameters are changed according to SLs. Even under conditions where nonlinear electron resonance heating caused by the self-excitation of the plasma series resonance due to the geometric reactor asymmetry plays an important role, the electron kinetics are shown to be invariant. Moreover, the validity of SLs for the ion dynamics is demonstrated. The results advance the applicability of SLs to a 2D cylindrical reactor geometry with azimuthal symmetry, indicating broad application prospects in practice.
