Published: July 2023

Abstract
Silicate glasses with metallic nanoparticles (NPs) have been of intense interest in art, science and technology as the plasmonic properties of the metallic NPs equip glass with light modulation capability. The so-called striking technique has enabled precise control of the in-situ formation of metallic NPs in silicate glasses for applications from coloured glasses to photonic devices. Over the past two decades, there has been a large amount of work to adapt the striking technique to form gold or silver NPs in tellurite glasses that exhibit the unique combination of easy fabrication, low phonon energy, wide transmission window and high solubility of luminescent rare earth ions. Nevertheless, the control of the in-situ formation of metal NPs and hence their plasmonic features in tellurite glasses has remained insufficient for photonic applications. Here, we first uncover the challenges of the traditional striking technique to create gold NPs in tellurite glass. Then, we demonstrate precise control of the size and concentration of gold NPs in tellurite glass by developing new approaches to both steps of the striking technique: a controlled gold crucible corrosion technique to incorporate gold ions in tellurite glass and a novel powder reheating technique to subsequently transform the gold ions to gold NPs. Using the Mie theory, the size, size distribution and concentration of the gold NPs formed in tellurite glass were determined from the plasmonic properties of the NPs. This fundamental research provides guidance to designing and manipulating the plasmonic properties in tellurite glass for photonics research and applications.

Abstract
The role of calcium-dependent processes in cardiac physiology and pathophysiology as well as the function of mitochondria as a regulator of myocyte calcium homeostasis have been extensively discussed. The aim of the present work was to evaluate the mechanism(s) of modulation of respiratory activity, morphology, permeability transition, and membrane potential of rat cardiac mitochondria by exogenous Ca2+ ions in the absence or in the presence of the plant flavonoid glucoside naringin. Low free Ca2+ concentrations (40–250 nM) effectively inhibited the respiratory activity of rat heart mitochondria: decreased the rates of succinate-dependent V2 and ADP-stimulated V3 respiration, remaining unaffected the efficacy of oxygen consumption. In the presence of high exogenous Ca2+ ion concentrations (the free Ca2+ concentration was 550 µM), we observed a dramatic increase in mitochondrial heterogeneity in size and electron density that was connected with calcium-induced opening of the mitochondrial permeability transition pores (MPTP) and membrane depolarization, observed at free Ca2+ concentrations of 150 to 750 µM. As compared to rat liver mitochondria, the sensitivity to Ca2+ of rat heart mitochondria was much lower in the case of MPTP opening and much higher in the case of respiration inhibition. Naringin, occurring naturally in citrus fruits, partially prevented Ca2+-induced rat cardiac mitochondrial morphological transformations (200 µM), dose-dependently inhibited the respiratory activity of mitochondria (10–75 µM) in the absence or in the presence of calcium ions and promoted membrane potential dissipation and mitochondria swelling in the absence of calcium ions but inhibited calcium-induced MPTP formation at higher concentrations (75 µM).

Abstract

Background There are numerous methods available to develop clinical prediction models to estimate the risks of a nominal polytomous outcome. A comprehensive evaluation of the most appropriate method has not yet been undertaken. We compared the predictive performance of a range of models in a simulation study and illustrate how to implement them with shrinkage in a clinical example. Methods Performance of models [One-versus-All with normalisation (OvA-N), One-versus-One with pairwise coupling (OvO-PC), two types of continuation ratio regression (c-ratio and c-ratio-all) and multinomial logistic regression (MLR)] was evaluated by calibration, discrimination and magnitude of overfitting. We considered two data generating mechanisms and 4 underlying data structures to allow us to evaluate how robust each method was to model mis-specification. Results At large sample sizes OvO-PC and MLR had comparative calibration across all scenarios. When the models were misspecified, MLR and OvO-PC had the best calibration, followed by c-ratio-all, and then c-ratio. Discrimination of all methods was similar across most scenarios, however c-ratio had poor discrimination in certain scenarios. At small sample sizes MLR and c-ratio had a similar level of overfitting, and OvO-PC suffered from the highest levels of overfitting. MLR and c-ratio-all had the best calibration, followed by OvO-PC and then c-ratio. OvA-N had the worst performance at both large and small sample sizes. Conclusions We recommend MLR for developing clinical predictions models for the prediction of polytomous outcomes as it was the most robust to model misspecification and suffered from the joint smallest levels of overfitting.

Abstract
Smart fabrics are one of the progressing technologies in this era especially in the field of self-cleaning and stain removing applications. Recent years, photocatalyst based self-cleaning technology seek much attention in the fields of therapeutic textiles, athletic clothing, defense uniforms and outdoor material. In this present work, the carbon nitride (C3N4) blended with conducting polypyrrole polymer (PPY) were coated over cotton fabrics by modified pad-dry cure method. The C3N4/PPY composite coated cotton fabric shows enhanced photocatalytic degradation efficiency of 96.5% compared to individual coatings of C3N4 and PPY. The photocatalytic stain removal and self-cleaning properties of C3N4/PPY composite coated cotton fabric was successfully demonstrated by using various colored stain under simulated solar irradiation. Also, the C3N4/PPY composite coated cotton fabric exhibited excellent resistance to bacterial growth. The dual advantages of photocatalytic antibacterial activity and self-cleaning of C3N4/PPY composite coated cotton fabric led to sustainable, innovative textile applications with significant lower water consumption during washing process.

Published: July 2023

Abstract

Wooded pastures combine trees and pastures in an integrated land resulting from traditional silvopastoral practices. With their sparse tree cover, wooded pastures are expected to represent an ecotone between open area pastures and forests with potentially high species diversity, although this remains to be tested for animal groups including ground beetles. In this study, we aimed to characterise and compare species communities, diversity indices, biomass and ecological traits of ground beetles in wooded pastures, forests and non-wooded pastures. Pitfall traps were set up in 29 study sites located in the Swiss Jura mountains. Ground beetle communities in wooded pastures largely encompass those in open pastures and forests, although some species are found only in forests or open areas. Wooded pastures and open pastures have an equivalent species diversity level, which is significantly higher than the one in forests. Ground beetle diversity is positively correlated with the existence and surface of Biodiversity Promotion Areas. Areas with high tree cover (70–100%) favour brachypterous and hygrophilic species, whereas areas with reduced tree cover (0–20%) favour xerophilic and winged species. Ground beetles' size and biomass increase with tree cover. Wooded pastures are an important ecotone, ensuring a gradual change of land use systems between open areas and forests, where a wide range of species from both land use systems are found. This semi-natural habitat plays an important function in the conservation of ground beetles.
Magma convection in hybird granitic chamber and formation of cognate mafic enclaves

Published: July 2023

Abstract
Mafic enclaves in granite are generally considered to represent coeval mafic melts that derived from metasomatized mantle, which can provide key information about crust-mantle interaction. Zircon U-Pb dating indicate that the mafic enclaves (219 ± 4.6Ma) display identical ages with the host monzogranite (214 ± 2.8Ma). Detailed whole-rock chemistry and zircon Lu-Hf works for the Triassic Zhaishui pluton reveal a cognate origin. Both of them share similar trace element geochemistry and zircon Lu-Hf isotopic compositions (monzogranite: εHf(t)= -0.99 to + 1.98; mafic enclaves: εHf(t)= -0.45 to + 3.26), suggesting common source region. However, detailed mineral chemistry reveals different crytallization condition between the mafic enclaves and host monzogranite. The amphibole in mafic enclaves reveal higher temperature and pressure (757℃, 2.65kbar) than those of the host monzogranite (733℃,1.96kbar). The temperature and pressure (587℃, 0.95kbar) of the Biotite in t mafic enclaves are consistent with that of the host monzogranite (599℃, 1.08kbar). Apatite in the mafic enclaves display slightly higher volatile contents (0.72 wt.%) than those of the apatite in the monzogranite (0.66 wt.%). These results indicate that the mafic enclaves represent early mafic accumulation in hybird granitic chamber, subsequent convection in magma chamber resulted in the formation of the mafic enclaves.

Abstract
This study investigates the composition of bycatch and the maturity status of some commercial fish caught by fishing boats equipped with shrimp trawls in the Dayyer-Nakhiloo and Mond marine protected areas in Bushehr, located in the north of the Persian Gulf. Cruises were conducted by fishing boats equipped with 27-foot length and 115-horsepower engines between August 18th and September 20th in 2020 and 2021. The trawl nets were made of polyamide (PA) and had mesh sizes of 50 mm in the body and 40 mm in the bag (STR). After 32 haulings, a total of 37 aquatic species were caught as bycatch. Greater lizardfish (Saurida tumbil), largescale tonguesole (Cynoglossus arel), blue swimming crab (Portunus segnis), whipfin silver-biddy (Gerres filamentosus), spotted sicklefish (Drepane punctata), elongate sole (Solea elongata), and orange-spotted grouper (Epinephelus coioides) were the most frequently caught species in all seasons. The results of the bycatch weight showed that the highest and lowest amounts of bycatch weight were observed in the 18th and 3rd fishing operations in the Mond region, respectively, with 234 kg and 4 kg. Similarly, the highest and lowest amounts of catch per unit effort (CPUE) were observed in the 18th and 9th fishing operations in the Mond region, respectively, with 234 kg h-1 and 3.25 kg h-1. The bycatch to shrimp ratio (r) was computed as 2.32:1. The results of species dominance showed that Acanthopagrus arabicus (9.4%), Scomberomorus commerson (7.75%), and Saurida tumbil (6.05%) had the highest percentage of abundance during the study period. Length frequency data of commercial fish caught showed that Parastromateus niger (44.19%) and Acanthopagrus arabicus (33.81%) had the highest percentage of mature fish in the specimens, while Scomberomorus commerson and Epinephelus coioides had the highest percentage of immature fish (100%). Overall, the present study indicates that bottom trawling by fishing boats in Dayyer-Nakhiloo and Mond marine protected areas poses a threat to the biodiversity of the Persian Gulf. An efficient management approach is therefore essential to promote responsible fisheries in the region.

AbstractThe paper gives the detailed information about a newly developed plasma system applicable for conductive target non-thermal plasma indirect treatment. High voltage microsecond duration pulses delivered in the kHz range are used to ignite a discharge in a glass funnel vessel flushed with argon and equipped with a needle electrode. An air dielectric barrier discharge (DBD) can subsequently be generated if a grounded grid is set a few millimeters apart from the thin glass plate constituting the funnel base, in the funnel-DBD setup. Thus, this air DBD operates with its powered electrode consisting in the transient argon streamer discharge spreading inside the funnel and over the glass plate. This “plasma electrode DBD” is characterized using time-resolved ICCD imaging together with voltage and current probes. This work reports for the first time the funnel-DBD proof of concept operation and its potentialities for large surface decontamination. Argon and air plasma temporal and spatial development is documented and analyzed while electrical characterization using Lissajous plots provide key information on the power and capacitances of the funnel-DBD setup. It is reported that the funnel-DBD operates as a large surface and low power discharge. As with any air-DBD plasma, the modulation of the power density delivered across the air-DBD, processed with changing the pulse repetition rate, results in the control of the ozone concentration. Beyond the plasma electrode-DBD development and characterization, the main motivation of this work is the treatment of conductive samples with the perspective of large surface decontamination. Preliminary demonstrations of the bacterial and yeast inhibition are thus reported forin vitrocultivations through indirect treatment with the funnel-DBD delivering reactive nitrogen and oxygen species.
Instability and Ultra-high frequency spectrum pulse train in passively Q-switched Yb: LuAG ceramic laser
Authors: Dai Min 
Published: July 2023

Abstract
Passive Q-switched pulse lasers equipped with high quality gain media are expected to be the preferred UHF pulse sources containing THz pulse train. Based on a Yb: LuAG passively Q-switched laser pumped by a laser diode with a Yb ratio of 15at.% in Yb: LuAG, stable quasi-single longitudinal mode laser pulse trains and quasi-double longitudinal mode oscillation unstable pulse trains were observed experimentally, and the ultra-high-frequency (UHF) pulses excited by the high power unstable pulse trains were studied. The spectrum of the pulse train includes the low frequency spectrum with the base frequency below 500 KHz and the ultra-high frequency spectrum with the base frequency above 104 KHz. The base frequency change law of UHF spectrum with the increase of pump power conforms to the frequency doubling frequency principle of spectrum changing to higher frequency. With the increase of pump power, the fundamental frequency increases by 2n, reaching 0.32 THz in the experimental range of this paper. After the UHF pulse train is filtered at 1.25*105 KHz, a single UHF pulse train and its corresponding spectrum are obtained. The average peak power of UHF spectrum pulse increases with the increase of pump power.

Published: July 2023

Abstract
The objective of this study was to analyze the effect of extending rotation at the stand level in private landowner of Eucalyptus globulus, Eucalyptus nitens and Pinus radiata established in contrasting productivity zones. The analysis also evaluates the impact of uncertainty in financial risk considering variations in the price per Mg of CO2 stored, costs of silvicultural activities, wood products yield using the ad-hoc simulator growth model and the discount rate. Deterministic results show that lower productivity environment the rotation age can be extended 7 or more years in EUGL and 6 or more in EUNI, with respect to the 12-year baseline. Extending PIRA rotation age resulted in a negative CO2 NPV, implying that a decision made at establishment to extend the harvest age beyond 22-years baseline will not increase financial returns, when aiming at potential payments for environmental services based on carbon storage. Sensitivity analysis shows that the uncertainties of the stored CO2 price, pulpable product and discount rate are the main contributors to the total variance in the 13-year NPV of both Eucalyptus species. The uncertainty in price of captured CO2 contributes more than 50% in either species, with pulpable product and discount rate contributing more than 16 and 4%, respectively.
Hepatoprotective effect of nicotinamide versus lead-motivated hepatotoxicity in rats via correcting effect on nuclear factor-kβ pathway and glutathione metabolism
Authors: Mahdavifard Sina , Shahi Zahra 
Published: July 2023

Abstract
Objective(s):
Many years ago, until now, lead (Pb) poisoning is one of the pivotal environmental issues. Pb prompts liver dysfunction by elevating inflammation following oxidative stress. Consequently, we for the first time investigated the effect of nicotinamide (B3) on the rat's liver histopathological and biochemical profiles in a rat model of Pb toxicity.
Materials and Methods
Thirty-six rats were shared into four groups (nine rats in each): untreated normal (N), B3 treated normal (N-B3), lead toxicity (Pbt), and B3 lead toxicity (Pbt-B3). Treated groups took B3 (180 mg/L in drinking water for one month). Pb intoxication was motivated in rats by acquiring 50 mg/l lead acetate from drinking water. Oxidative stress markers (advanced protein oxidation products, and malondialdehyde), antioxidant markers (total glutathione, reduced (GSH) to oxidized (GSSG) glutathione ratio, ferric ion reducing power, catalase, and paraoxonase-1), and inflammatory markers (hepatic nuclear factor-kβ expression, interleukin 1β level, and myeloperoxidase activity) in sera and liver homogenates were determined. Further, Biochemical liver function indicators (Alanine transaminase, aspartate transaminase, alkaline phosphatase, gamma-glutamyl transpeptidase, total bilirubin, total protein, albumin, and globulins) were quantified. Pb-induced liver damage was assessed with Histopathological observation. Results: B3 corrected lead-persuaded biochemical and histopathological changes in the rat's liver. In addition, treatment diminished Pb, oxidative stress, and inflammatory markers in the sera and liver homogenates of N-B3 and Pbt-B3 groups as well as elevated antioxidant markers (p < 0.001).
Conclusions
Nicotinamide through a decrease in Pb, oxidative stress, and inflammation prevented Pb prompted liver histopathological alternations and reduced liver dysfunction parameters.
Research on the evolution and height prediction of WCFZ in shallow close coal seams mining

Abstract
Based on the mining conditions of shallow close coal seams in the Jurassic coalfield of northern Shaanxi, in order to explore the evolution and development height prediction of WCFZ (WCFZ), combining with measured statistical analysis, physical simulation, numerical calculation, and theoretical analysis, the evolution of mining-induced fractures and the development characteristics of WCFZ are analyzed, and the development height predicting method of WCFZ in shallow close coal seams mining is proposed. The results show that in shallow single coal seam mining, during the stage of incritical mining, the height of the WCFZ increases in a "jumping" pattern with the main roof periodic caving. After critical mining, it is basically stable. Its development height is positively correlated with the mining height. The ratio of development height to mining height is generally 20–30, and the change is not significant with the mining height, overall, the distribution of the WCFZ is "saddle shaped". Based on close distance coal seams repeated mining, the primary fractures act as activation development when the interburden broken completely, the development of WCFZ at the mining boundary is significantly intensified, and ratio of the height to mining height in repeated mining is obviously lower than that in single seam mining, which is generally 18–25. The traditional empirical formula cannot be applied to the development prediction in shallow close coal seams mining, with an error of 10%-50%. Considering the mining height, interburden thickness, and roof caving characteristics, the development height predicting method of WCFZ in shallow close coal seams mining is proposed. Compared with measured results, the calculation error is basically within 15%, which has good prediction accuracy, The research results can provide a theoretical basis for predicting the height of WCFZ in shallow close coal seams mining in the Jurassic coalfield of northern Shaanxi.
