Compilation of state tax relating to oil, gas, and mining properties in New Mexico
Authors: Ripley E. P. 
Published: March 2023

The numerous inquiries received by the New Mexico Institute of Mining and Technology and the State Bureau of Mines and Mineral Resources have indicated the need for a recompilation of the tax law relating to taxation of mineral properties within New Mexico.Broadly speaking, there are three classes of taxes levied on mineral properties: (1) Ad Valorem and Production Taxes; (2) Severance Taxes, and (3) Sales Taxes. This recompilation will follow this division. In an effort to make the compilation of maximum benefit, reproductions of the forms currently in use by the Tax Commission and the Bureau of Revenue are appended. Decisions of the Supreme Court on the subject also are referred to. However, no attempt is made to cover court decisions in detail, their inclusion in abbreviated head-note form makes the full text readily available to interested persons. This compilation does not deal with corporate taxes nor the State income tax.Citations are to New Mexico Session Laws and to 1941 New Mexico Compilation and Cumulative Pocket Supplement thereof (Boobs-Merrill Company, 1942).
Electrode improvement and neural network-based dynamic optimization of vanadium redox flow battery
Authors:   , Chutimasakul Apisada 
Published: March 2023

The performance improvement of a vanadium redox flow battery (VRFB) was focused on this study. The two objectives of this study were (1) to investigate the effect of the operating temperatures of the Atmospheric Pressure Plasma jets (APPJs) process on the energy efficiency of the VRFB and (2) to determine the optimal electrolyte flow rate of the VRFB by solving a dynamic optimization based on a neural network model of the VRFB. The APPJs graphite felt electrode treatment temperature providing the highest energy efficiency of the VRFB was 550°C, explained by the Energy Dispersive X-ray Spectrometry (EDX) and X-ray photoelectron spectroscopy (XPS) results. The EDX results indicated that the electrode treated with APPJs at 550°C had a high percentage of the oxygen atom, and XPS results illustrated the highest C=O functional group on the surface of APPJs at 550°C electrode comparing to the APPJs at other temperatures and sulfuric treatment. Moreover, the wettability of the electrode with APPJs treatment at all temperatures was higher improved than that with a sulfuric acid treatment and an untreated one. However, the electrode treatment did not visibly change the surface of the electrode, as shown in Scanning Electron Microscopy (SEM) results. In the second part of this study, an optimization of the electrolyte flow rate based on a neural network (NN) model of the VRFB was investigated. The NN was separately trained between the charging and discharging process using a nonlinear autoregressive with external input (NARX) model. The training and testing results indicated a high accuracy of the NN model. Under the optimal electrolyte flow rate obtained by solving the NN based-optimization, the VRFB provided a high system efficiency (SE) due to reducing the concentration overpotential. It demonstrated that the NN model could replace the theoretical model used in the dynamic optimization, even though the performance of the VRFB under the optimal electrolyte flow rate obtained from the NN-based optimization is slightly lower than that from the theoretical model-based optimization.
Novel electrochemical packed-bed reactor for carbon dioxide reduction
Authors:   , Chaiwarit Suwakul 
Published: March 2023

Electrochemical reduction of carbon dioxide (CO2) is a promising strategy to recycle CO2 into valuable chemical products. Nevertheless, a conventional apparatus which usually utilizes stack design to maximize its surface-to-volume ratio requires many elements and complicated instruction assembly. The stack design often requires feed streams to flow in narrow channels throughout the cell, which is also constrained by membrane size roughly 1 m2 by current manufacture technology. This research focuses on development of a new type of electrochemical reactor that is suitable for industrial-scale applications. The novel electrochemical packed-bed reactor is designed for the electroreduction to covert CO2 into CO in the gas phase. Humidified CO2 was fed through the reactor, and a voltage was applied to the bed for initiate electrochemical reactions. The bed consists of 3 compartments including Zinc (Zn) deposited felt, ion-exchange resin, and platinized titanium arranged in this order. Effects of applied voltage and CO2 flow rates toward the CO2 reduction performance was investigated. The increasing of CO concentration and current were achieved with increasing voltage. The maximum CO concentation and the highest faradaic efficiency were observed at 6 V and 80 ml min-1 for a single-cell bed. The optimal condition for a two-cell bed was 11 V and 120 ml min-1. However, the effects of flow rate might oppose effects of mass transfer at high flow rate. An online infrared spectroscopy was coupled to the novel electrochemical packed-bed reactor for the CO product detection. The CO product analysis confirmed that the novel electrochemical packed-bed reactor successfully converts CO2 to CO.
Assessing arthropod diversity metrics derived from stream environmental DNA: spatiotemporal variation and paired comparisons with manual sampling
Authors: Aunins Aaron A. , Mueller Sara J. , Fike Jennifer A. , Cornman Robert S. 
Published: March 2023

Background
Benthic invertebrate (BI) surveys have been widely used to characterize freshwater environmental quality but can be challenging to implement at desired spatial scales and frequency. Environmental DNA (eDNA) allows an alternative BI survey approach, one that can potentially be implemented more rapidly and cheaply than traditional methods.

Methods
We evaluated eDNA analogs of BI metrics in the Potomac River watershed of the eastern United States. We first compared arthropod diversity detected with primers targeting mitochondrial 16S (mt16S) and cytochrome c oxidase 1 (cox1 or COI) loci to that detected by manual surveys conducted in parallel. We then evaluated spatial and temporal variation in arthropod diversity metrics with repeated sampling in three focal parks. We also investigated technical factors such as filter type used to capture eDNA and PCR inhibition treatment.

Results
Our results indicate that genus-level assessment of eDNA compositions is achievable at both loci with modest technical noise, although database gaps remain substantial at mt16S for regional taxa. While the specific taxa identified by eDNA did not strongly overlap with paired manual surveys, some metrics derived from eDNA compositions were rank-correlated with previously derived biological indices of environmental quality. Repeated sampling revealed statistical differences between high- and low-quality sites based on taxonomic diversity, functional diversity, and tolerance scores weighted by taxon proportions in transformed counts. We conclude that eDNA compositions are efficient and informative of stream condition. Further development and validation of scoring schemes analogous to commonly used biological indices should allow increased application of the approach to management needs.
miR-126 promotes M1 to M2 macrophage phenotype switching via VEGFA and KLF4
Authors: Shou Xinyang , Wang Yimin , Jiang Qingyu , Chen Jun , Liu Qiang 
Published: March 2023

Background
Macrophage polarization and microRNA play crucial roles in the development of atherosclerosis (AS). The M1 macrophage phenotype contributes to the formation of plaques, while the M2 macrophage phenotype resolves inflammation and promotes tissue repair. MiR-126 has been found to play a role in regulating macrophage polarization in the context of AS. However, the exact mechanism of miR-126 requires further research.

Methods
The foam cell model was established by stimulating THP-1 with oxidized low-density lipoprotein (ox-LDL). We transfected foam cells with miR-126 mimic and its negative control. The transfection of miR-126 was implemented by riboFECT CP transfection kit. The levels of miR-126 and M1/M2 associated genes in foam cells were quantified using reverse transcription-quantitative PCR (RT-qPCR). Additionally, the expressions of CD86+ and CD206+ cells in foam cells were determined by flow cytometry. Western blotting and RT-qPCR were used to determine the protein and mRNA levels of the vascular endothelial growth factor A (VEGFA) and the transcriptional regulator Krüppel-like factor 4 (KLF4), respectively. Additionally, we detected endothelial cell migration after co-culturing endothelial cells and macrophages. MG-132 was used to indirectly activate the expression of VEGFA, and the expression of KLF4 was also evaluated.

Results
The activation of apoptosis and production of foam cells were boosted by the addition of ox-LDL. We transfected foam cells with miR-126 mimic and its negative control and observed that miR-126 greatly suppressed foam cell development and inhibited phagocytosis. Moreover, it caused pro-inflammatory M1 macrophages to switch to the anti-inflammatory M2 phenotype. This was reflected by the increase in anti-inflammatory gene expression and the decrease in pro-inflammatory gene expression. Additionally, miR-126 dramatically decreased the expressions of VEGFA and KLF4. The protein-protein interaction network analysis showed a significantly high correlation between miR-126, VEGFA, and KLF4. MiR-126 may also promote EC migration by activating macrophage PPAR γ expression and effectively suppressing macrophage inflammation. MG-132 indirectly activated the expression of VEGFA, and the expression of KLF4 also significantly increased, which indicates a direct or indirect relationship between VEGFA and KLF4.

Conclusion
Our study shows that miR-126 can reverse ox-LDL-mediated phagocytosis and apoptosis in macrophages. Consequently, the potential role of miR-126 was manifested in regulating macrophage function and promoting vascular endothelial migration.

Published: March 2023

Aims: This study was initiated to assess the knowledge of human papillomavirus (HPV) infection and vaccination, attitudes towards HPV vaccines, as well as risky sexual practices of young university students towards HPV infection.
Study Design: This was a cross-sectional descriptive study that included university-going young adults of both sexes, aged 18 to 25 years.
Place and Duration of Study: The study was conducted in four randomly selected state universities, located in different geographic regions of Cameroon. The study took place between April and July 2022.
Methodology: The survey instrument was a self-administered anonymous questionnaire. Participants were randomly given questionnaires to be completed. Data was imported into SPSS version 23 software for analyses. Participants were categorised into one of two groups - poor level of knowledge and good level of knowledge, depending on the number of correct answers to 7 questions about knowledge of HPV infection and vaccination. Chi-square test and logistic regression were used to examine differences in parameters.
Results: 1263 questionnaires were returned. Most participants (78.9%) were undergraduates aged 20 - 21 years (32.7%). Overall, just 87/1263 (6.9%) of participants had a good knowledge of HPV infection and vaccination, most of whom were females (56.7%). Educational level (OR 3.11, 95% CI (1.24 – 7.85), P = .02), field of study (OR 0.42, 95% CI (0.17 – 1.04), P = .04) and plans to become vaccinated (OR 0.33, 95% CI (0.14 – 0.76), P = .009) were predictors of good knowledge of HPV. Attitudes towards HPV vaccination were overall positive. 71.9% participants were sexually active, most of whom only used condoms sometimes (47.2%).
Conclusion: These findings underscore the need for educational programs and public health policies targeted to this age bracket, to increase students’ awareness of the risks associated with HPV infection as this can potentially increase the vaccination rate in the country.

AbstractAn oxidative [3+2+1] cyclization of enaminones and N‐alkenyl‐2‐pyrrolidinone is described for the synthesis of 4‐alkylated 1,4‐dihydropyridines (1,4‐DHPs). By using terminal olefin as the C4 source of the 1,4‐DHP skeleton, this synthetic strategy provides a series of 1,4‐DHPs through a 1,1‐difunctionalization/cyclization process. In this protocol, two C(sp3)−C(sp2) bonds and a C(sp2)−N bond are simultaneously formed, the hydrogen source on the newly formed methyl group of the 1,4‐DHP skeleton is confirmed and a possible mechanism is proposed.magnified image
Market power and cost‐efficiency effects: Broiler packing industry in South Korea
Authors: Kang Minseong , Ahn Byeong‐Il 
Published: March 2023

AbstractThe effects of rising concentration on markups in the meatpacking industry have sparked ongoing global debate. In this vein, our study aimed to decompose these effects into two opposing components: market power and cost‐efficiency effects. We applied our model to the broiler packing industry in South Korea. Our findings indicate that cost‐efficiency effects decreased sharply from 74.642 in 2017 to ‐145.860 in 2021, while market power effects remained stable during the study period. We found that the decrease in cost‐efficiency effects has begun to counteract the market power effects, which can largely be attributed to profix‐maximizing behavior of broiler packers in response to the bird flu outbreak. Moreover, we highlighted that non‐material price changes were a significant source of the reduction in cost‐efficiency effects, which underscores the necessity of policy efforts to manage factor market situations in order to mitigate the negative consequences of market concentration.

Published: March 2023

AbstractThe advent of wearable electronics has strongly stimulated advanced research into the exploration of flexible zinc−air batteries (ZABs) with high theoretical energy density, high inherent safety, and low cost. However, the half‐open battery structure and the high concentration of alkaline aqueous environment pose great challenges on the electrolyte retention capability and the zinc anode stability. Herein, a starch‐based superabsorbent hydrogel polymer electrolyte (SSHPE) with high ionic conductivity, electrolyte absorption and retention capabilities, strong alkaline resistance and high zinc anode stability has been designed and applied in ZABs. Experimental and calculational analyses probe into the root of the superiority of SSHPEs, confirming the significance of the carboxyl functional groups along their polymer chains. These features endow the as‐fabricated ZAB a long cycle life of 300 h, much longer than that with commonly used poly(vinyl alcohol)‐based electrolyte.
Selective Production of CO from Organic Pollutants by Coupling Piezocatalysis and Advanced Oxidation Processes
Authors: Ran Maoxi , Xu Hai , Bao Yan , Zhang Yayun , Zhang Jinlong , Xing Mingyang 
Published: March 2023

AbstractTo date, the chemical conversion of organic pollutants into value‐added chemical feedstocks rather than CO2 remains a major challenge. Herein, we successfully developed a coupled piezocatalytic and advanced oxidation processes (AOPs) system for achieving the conversion of various organic pollutants to CO. The CO product stems from the specific process in which organics are first oxidized to carbonate through peroxymonosulfate (PMS)‐based AOPs, and then the as‐obtained carbonate is converted into CO by piezoelectric reduction under ultrasonic (US) vibration by using a Co3S4/MoS2 catalyst. Experiments and DFT calculations show that the introduction of Co3S4 not only effectively promotes the transfer and utilization of piezoelectric electrons but also realizes highly selective conversion from carbonate to CO. The Co3S4/MoS2/PMS system has achieved selective generation of CO in actual complex wastewater treatment for the first time, indicating its potential practical applicability.

Probing Tyrosine Nitration with a Small TbIII‐Metallopeptide
Authors: Sánchez‐Fernández Rosalía , Sánchez‐Temprano Agustín , Esteban‐Gómez David , Pazos Elena 
Published: March 2023

AbstractTyrosine nitration, a post‐translational modification (PTM) that takes place under nitrosative stress conditions, occurs through a non‐enzymatic peroxynitrite‐mediated reaction. Although protein nitration has long been considered an irreversible PTM involved in nitrosative stress‐associated diseases, it has also been suggested to be a regulatory mechanism of signal transduction. Therefore, the development of tools that help to understand this protein modification is of great interest. Herein, we explore a TbIII‐chelating metallopeptide to monitor tyrosine nitration. The luminescence of this probe decreases significantly between its non‐nitrated and nitrated states, and this reduction in the luminescence intensity is directly related to the degree of tyrosine nitration after treatment with peroxynitrite. Remarkably, the luminescence intensity changes after nitration are not affected in the presence of complex biological media, which makes it a promising tool for understanding this protein modification.

Published: March 2023

AbstractThis study assessed, for the first time, the expression of the genes hOGG1, TP53, and IL‐6 in leukocytes by real‐time quantitative polymerase chain reaction in surgical patients before (baseline), during (2 h of anesthesia) and 1 day after sevoflurane anesthesia. Additionally, DNA damage was detected by the comet assay, serum interleukin (IL)‐6 was detected by flow cytometry, and differential leukocyte counting was also performed. TP53 and hOGG1 expression was downregulated on the day after anesthesia compared to before anesthesia. However, IL‐6 expression did not change, and no DNA damage induction was observed during or after anesthesia. At the systemic level, mild neutrophilia and an increase in IL‐6 levels occurred after anesthesia. Our findings suggest that sevoflurane anesthesia downregulates gene expression (hOGG1 and TP53) and contributes to an inflammatory status (increased systemic IL‐6 and mild neutrophilia) but is not associated with DNA damage in patients without comorbidities who undergo minor elective surgery.
Effect of weathering on short‐ and long‐term mechanical behaviour of granitic soils from the Benggang area under unloading conditions

Published: March 2023

AbstractAs regional soils collapse during the development of Benggang landforms, the release of geostress results in soil disintegration. This phenomenon is associated with soil instability, and it necessitates a study on the mechanical behaviour of decomposed granitic soils in response to unloading in the Benggang area. This study addressed the short‐ and long‐term mechanical behaviour of granitic soils with various degrees of weathering in response to unloading. Triaxial unloading and multi‐stage unloading creep tests were performed, including a comparative study of consolidated undrained (CU) triaxial tests. The deformation characteristics of granitic soils differed with the degree of weathering and the initial stress level. The most significant adverse effect of creep behaviour under unloading and undrained conditions was found in granitic soils with the greatest loss rate of maximum shear stress in contrast to the cases of CU compression and one‐time unloading. Additionally, increasing time‐dependent deformation was observed with increasing degree of weathering and initial stress level, which suggested that creep behaviour under unloading conditions accelerated soil erosion and instability in the Benggang area. The results of this study highlighted the potential influences of geostress release and time‐dependent deformation on soil instability in the Benggang area and advanced the understanding of mechanical mechanisms during the development of Benggang landforms.
