description: In studies of plastic ingestion by marine wildlife, visual separation of plastic particles from gastrointestinal tracts or their dietary content can be challenging. Earlier studies have used solutions to dissolve organic materials leaving synthetic particles unaffected. However, insufficient tests have been conducted to ensure that different categories of consumer products partly degraded in the environment and/or in gastrointestinal tracts were not affected. In this study 63 synthetic materials and 11 other dietary items and non-plastic marine debris were tested. Irrespective of shape or preceding environmental history, most polymers resisted potassium hydroxide (KOH) solution, with the exceptions of cellulose acetate from cigarette filters, some biodegradable plastics and a single polyethylene sheet. Exposure of hard diet components and other marine debris showed variable results. In conclusion, the results confirm that usage of KOH solutions can be a useful approach in general quantitative studies of plastic ingestion by marine wildlife.

description: Solar flares are magnetic reconnection events resulting in sudden bursts of electromagnetic energy, particle acceleration, and hot plasma heated to over 10 MK. Hot solar flare plasma generates copious soft X-rays. Hence, spectral soft X-ray measurements provide great constraints on flare plasma temperature and dynamics. Flare observations from Low-Earth orbiting satellites like the first Miniature X-ray Solar Spectrometer (MinXSS-1) CubeSat can be occulted for 30 minutes of the 90 minute orbit, missing vital portions of the temporal evolution of the spectrum and plasma. In this project, the eclipsed MinXSS-1 spatially integrated spectra from 0.8 - 15 keV is reconstructed using non-oculted data by fitting an empirical piecewise temporal-spectral function consisting of Gaussian, Lorentian, and polynomial components. This automated pro- cedure fits the original data and adds synthetic data points to the eclipse period in the temporal profile, which can be used to reconstruct the spectral profile for energy range specified in the time series. At both points of egress and ingress there are larger decreases in the low energy (< 3 keV) soft X-ray flux due to absorption by nitrogen and oxygen in Earth’s atmosphere. Results from this project could be used in future projects focusing on exoplanet atmospheres and models of flare plasma evolution.

description: The aim of this work was to determine phenolic acid and flavonoid contents, as well as antioxidant properties of propolis from different regions of Poland. Total phenolic content of propolis samples ranged from 150.05 to 197.14 mg/g GAE, while total flavonoid content was 35.64–62.04 mg/g QE. The dominant phenolic acid was p-coumaric acid, the content of which was from 37.54 to 116.95 mg/g. The samples also contained much ferulic acid. Among the flavonoids, chrysine and galangine were dominant, and for two samples, naringine was dominant. The propolis samples exhibited various antiradical activity measured towards DPPH√ (1.92–2.69 mM TE/g) and ABTS√+ (3.96–4.98 mM TE/g) and reducing power was determined by the ferric reducing antioxidant power method (6.23–9.19 mM Fe(II)/g). The significant linear correlations between total phenolic content and antiradical activity and between total phenolic content and reducing power were observed. Moreover, the total flavonoids content significantly correlated with antiradical activity and reducing power.

description: This work presents a geomorphological map of the Feltrino Stream basin and minor surrounding coastal basins (scale 1:20,000), located in the south-eastern Abruzzo area (Central Italy), across the Adriatic piedmont of the Maiella massif (Central Apennines). This geomorphological mapping is focused on near-surface deposits and hillslope evolution analysis and includes three sections: main geomorphological map; orography and hydrography; and geomorphological models of hillslope evolution. In the study area, landforms and continental near-surface deposits are mainly linked to slope and fluvial processes, even though structural, marine, and anthropogenic landforms are also present. The mapping is primarily focused on near-surface deposits and landforms related to the evolution of hillslopes, resulting from the combination of tectonic (regional uplift) and surface processes. At a local scale, it can contribute to an understanding of the causes, mechanisms, and consequences of the changes of landforms and hillslopes and help solve engineering geomorphological problems. Finally, it is also a tool for the assessment of geomorphological hazards in landscapes characterized by widespread near-surface deposits and intense and rapid geomorphological processes, as well as a tool for land management.

description: Supra-arcade downflows (SADs) have been observed above flare loops during the decay phase of flare. They appear as tadpole-like dark plasma voids traveling towards the Sun. In areas surrounding where they appear, temperatures are often high. We aim to investigate temperature and heating mechanism of SADs. We apply our analysis to the M1.7 flare that occurred on 2012 July 12 and was observed by the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory. There are many obvious SADs above the arcade during this event in the AIA 131 Å channel. We calculate velocities of SADs using the Fourier Local Correlation Tracking (FLCT, Fisher & Welsch, 2008) method to derive velocities in the supra-arcade region. Using corks to track the calculated velocities, we find our velocity results are consistent with the SAD motions in the AIA 131 Å intensity movie. We use the velocities to derive the adiabatic heating caused by the compression of plasma. Preliminary results indicate that there is adiabatic heating in front of the SADs.

description: The aim of this study was to explore the protective effects of Trichosanthes kirilowii ethanol extract (TKE) against cisplatin-induced acute renal failure (ARF). In the in vitro study, TKE-pretreated porcine kidney cells (PK15) exhibited enhanced cell viability after cisplatin (15 μg mL− 1) treatment in both MTT and crystal violet assays. PK15 cells pretreated with TKE (50 μg mL− 1) exhibited increased glutathione content, decreased reactive oxygen species production and ameliorated p53 expression. In vivo study, rats were administered with TKE for 4 weeks before cisplatin (5 mg kg− 1) injection. TKE (100 mg kg− 1) decreased blood urea nitrogen and creatinine levels by 24% and 47%, respectively, in comparison with cisplatin-alone group. In addition, TKE pretreatment ameliorated cisplatin-induced oxidative stress, as evidenced by increased antioxidative enzyme levels and decreased lipid peroxidation levels. Moreover, TKE pretreatment reduced histopathological alterations in the kidney with decreased apoptotic cells. Taken together, TKE might be beneficial in treating cisplatin-induced ARF.

description: RESUMENEste estudio investiga la ruptura del consenso en torno al Estado autonómico español, surgido durante la Tran-sición a la democracia, tras la emergencia de un partido de derecha radical, Vox, de ideología centralista y nacionalista española. El análisis basado en la explotación de una encuesta de tipo panel se centra en cómo la aparición de Vox en las elecciones regionales andaluzas de diciembre de 2018 acabó con la espiral de silencio relacionada con el debate sobre la organización territorial de España. Hasta ahora, la literatura y la evidencia empírica habían demostrado un consenso a favor del Estado autonómico. Sin embargo, nuestros hallazgos sugieren que la emergencia de Vox animó a quienes se identifican exclusivamente con España a expresar públicamente sus opiniones a favor de un modelo territorial centralizado. Además, se comprueba la función catalizadora de Vox en la expresión de opiniones contrarias al statu quo, desbloqueando el tabú del centralismo.

Subjects: Sun: atmosphere, line: profiles, planets and satellites: atmospheres, planets and atmospheres: gaseous planets

description: Exoplanet research has become a major focus due to advancements like the transit method, which allows us to observe the features of exoplanet atmospheres. Shared features between exoplanetary atmospheres and their host stars limits confidence on any atmospheric interpretation. Our ability to characterize the variability of these shared stellar features is critical in accurately characterizing planetary atmospheres. The Helium I 1083 nm line is one such shared feature and is an ideal absorption line to study when probing the upper atmosphere of certain exoplanets for atmospheric escape. By investigating the variability of the He I 1083nm absorption line in the Sun we can begin to understand how the feature behaves in other sunlike stars. I analyzed publicly available SOLIS/ISS spectra of the Sun as a star to document how the He I 1083nm line strength changed as a function of time. Using the Sherpa model-fitting python package, I was able to calculate the equivalent widths for nearly 3,000 observations between 2007 and 2017. Tracking these fluctuations through both low and high stellar activity, which can be approximated by the S-index, can reveal more precise constraints on how we expect the line to vary during specific points in a star’s cycle. This analysis will allow us to better disentangle the stellar component of the He I 1083nm signal from exoplanetary atmospheres.

description: Despite economic transformations and urbanization, declining shares of the workforce employed in the agricultural sector, and gradual growth of agricultural mechanization, production costs in the agricultural sector and food prices remain high in Nigeria relative to those in some of the other developing countries. Understanding how the adoption of mechanical technologies is related to agricultural productivity is therefore important for countries like Nigeria. Using farm household data from northern Nigeria as well as various spatial agroclimatic data, this study shows that the adoption of key mechanical technologies in Nigerian agriculture (animal traction, tractors, or both) has been high in areas that are more agroclimatically similar to the locations of agricultural research and development (R&D) stations, and this effect is heterogeneous, being particularly strong among relatively larger farms. Furthermore, such effects are likely to have been driven by the rise in returns on scale in the underlying production function caused by the adoption of these mechanical technologies. Agricultural mechanization, represented here as the switch from manual labor to animal traction and tractors, has been not only raising the average return on scale but also potentially magnifying the effects of productivity-enhancing public-sector R&D on spatial variations in agricultural productivity in countries like Nigeria.
Calculating the Emission Measure and Weighted Temperature Average of Supra-arcade Downflows

Year: 2020

description: We examine the thermal state of plasma associated with a solar flare that occurred July 7, 2012. In the plasma sheet located within the region above the flare, supra-arcade downflows (SADs) are observed using the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory. The sunward traveling downflows give insight on the local heating mechanics of coronal plasma during the post-eruption period of the flare. We perform calculations of the differential emission measure (DEM) from the AIA data in order to determine the total emission measure and the average weighted temperature. Emission within the SADs are relatively low, and the temperature is much cooler compared to the surrounding plasma. Coupling the DEMs with the velocities within the plasma sheet, we can analyze potential heating terms that model dominant thermal processes in the supra-arcade region.

description: Aluminum (Al) is a trace element that may hamper plant growth and development. Tolerance mechanisms could imply the cell wall as it is the first barrier before entry into the plant cell. Douglas-fir plantlets were grown in vitro on media supplemented with different aluminum chloride (AlCl3) concentrations up to 1 mM. The characterization of the cell wall revealed quantitative and qualitative modifications in the polysaccharidic composition of the wall, in particular in roots whose pectins showed a higher galacturonic acid content with less ramification and a lower degree of methylesterification (DME) explained by a higher pectin methylesterase activity; these Al-induced changes suggest an Al-trapping process in cell wall structures. In stems and needles, the observed increase in DME rather suggests an exclusion of Al from the cell wall. Douglas-fir is a coniferous species that has shown tolerance against trace elements such as aluminum. In this study, changes in cell wall polysaccharides were observed in plants grown in the presence of Al, notably in roots. The contents and the structures of pectins were affected, leading to a trapping process in roots due to an abundance of low methylesterified pectins, and an exclusion process from the cell wall in stem and needles with less Al-binding sites in pectins.

description: Glyphosate can disrupt the food chain and harm non-target organisms, highlighting the need to remediate contaminated soils. This study sought to determine the efficacy of co-applying mixed microbial culture (MMC) and two different levels of nitrogen (50% and 100%) in glyphosate-contaminated soil (800 mg/kg) and to assess their role in maize (Zea mays L.) growth and physiology and glyphosate uptake by plants and removal from soil. The results showed that glyphosate posed significant phytotoxicity to maize plants by causing up to 43.7–91.5%, 8.60–54.3%, and 13.2–51.6% reduction in nutrient uptake, physiological, and growth attributes of maize plants in glyphosate-contaminated soil, respectively. The co-application of MMC and the recommended dose of 100% nitrogen significantly improved the agronomic (24.6–55.0%), nutrient uptake (37.4–90.0%), and physiological (16.9–54.0%) attributes of maize plants as compared to unamended contaminated controls. Although the individual application of MMC or N was effective in improving glyphosate removal from the soil, their co-application further enhanced this effect by removing glyphosate 85.8% higher than the respective control. This research strategy contributes to sustainable development goal 2 (zero–hunger) and 15 (life on land) by enhancing food production, remediating contaminated soil, and restoring the ecosystem. The higher phytotoxicity of glyphosate highlights the need to explore cost-effective and eco-friendly options (such as using microbes and appropriate amounts of plant nutrients) to remove glyphosate from the contaminated soil and alleviate its toxicity to plants. This study is the first to report the effective use of nitrogen and a newly developed mixed microbial culture in remediating soil contaminated with glyphosate and improving maize physiology and growth in contaminated soil. The results of this work offer fundamental but crucial insights into the synergistic application of nitrogen fertilizers and microbes for the restoration of glyphosate-contaminated environments.

description: Despite the importance of location-specific adaptive crop breeding research, past reforms of breeding systems in Nigeria have focused more on centralizing the breeding activities into fewer locations. This has been based partly on the premise that such research systems can still effectively meet the need for a diverse set of varietal technologies that are suitable for different agroecological conditions through the use of numerous outstations and multilocational trials, regardless of the locations of the headquarters or the outstations where breeders are located. However, little empirical evidence exists to support this premise. Using panel data for agricultural households in northern Nigeria, as well as spatial data on agroecological factors, this study fills this knowledge gap. Specifically, it empirically shows that agricultural productivity and technical efficiency at farm household level is significantly and positively affected by similarity between the agroecological conditions of the locations of these households and where major crop breeding institutes are headquartered in Nigeria, namely Maiduguri, Kano, Zaria, Badeggi, Ibadan, and Umudike, after controlling for the agroecological conditions and various relevant household characteristics of these households. These findings suggest that where improved varieties are developed or evaluated affects agricultural productivity and technical efficiency in different locations. Overall agricultural productivity in Nigeria can be significantly increased not simply by increasing support for public sector varietal development, but by doing so in a manner that increases the similarity in agroecological conditions between areas where crop breeding is conducted and the areas where farm households produce those crops.

The observed first-order rate constants followed the simple rate law kobs = k2[Nu]. The data obtained show that the ethylene glycoxy pendant, trans to the leaving group, acts as a σ-donor into the terpyridine ligand and is effective only up to n = 1, beyond which the substitution reactivity of the complexes are controlled by the steric influence of the appended ethylene glycoxy pendant units, which decreases with increase in the number of ethylene glycoxy units. The activation parameters obtained support an associative mechanism, where bond formation in the transition state is favored. The observed reactivity trends were supported by density functional theory calculations.

description: Co-cropping of hyperaccumulators is still poorly understood, while associations between hyperaccumulators and other plant species may promote beneficial plant interactions and lead to increased metal phytoextraction from contaminated soils. The aim of this study was to evaluate the phytoextraction potential of the Ni-hyperaccumulator Bornmuellera emarginata in different co-cropping combinations with Lupinus albus and Imperata cylindrica. Plants were grown in ultramafic soil in a growth chamber for 45 days and Al, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn concentrations in roots and leaves were analyzed. Translocation factors were used to evaluate Ni phytoextraction. Bornmuellera emarginata accumulated foliar Ni at contents ranging from 3,410 to 6,500 mg kg−1, with mean Ni concentrations in roots being seven times lower than in shoots (625–878 mg kg−1). Co-cropping led to a reduction in biomass (25–62%) of B. emarginata and did not substantially increase Ni concentrations in shoots. To conclude, intercropping did not significantly enhance Ni phytoextraction by B. emarginata. However, B. emarginata and L. albus in co-cropping showed high translocations (>1) for Co, Mn, Ni, and Zn, highlighting the potential of combining hyperaccumulators with other plant species as a viable strategy for phytoremediation of areas contaminated by multiple metals. The results of this show that Bornmuellera emarginata can be grown with other plants to remediate soils contaminated by multiple metals. The Ni phytoextraction efficiency of B. emarginata does not increase through co-cropping due to species competition and decreased biomass.

description: This study analyzed changes in physicochemical properties of the soil under various substrate conditions, as well as the interactions between ryegrass and heavy metals. Results indicated that biochar significantly improved soil physicochemical properties, such as an increase in electrical conductivity by 34.8%, enhancement of pH from 7.13 to 7.32, and augmentation in organic matter by 152%. Moreover, readily available phosphorus and alkali-hydrolyzable nitrogen increased by 237% and 122% respectively, while soil cation exchange capacity rose by 135%. This contributes to plant growth and the maintenance of soil fertility. The biochar addition also led to a decrease in the proportion of fine soil particles by 20%, significantly enhancing structure and stability of soil aggregates and promoting the formation of larger aggregates, crucial for improving soil aeration, water retention, and root permeability. The addition of biochar notably altered the chemical forms of heavy metals in soil, promoting their transformation from bioavailable forms to more stable and less toxic forms, effectively reducing the bioavailability and mobility of heavy metals, and decreasing their environmental toxicity. The addition of biochar, by changing the chemical forms of heavy metals, not only enhanced germination rate of ryegrass seeds but also improved the overall growth state of ryegrass. This study introduces a novel biochar-ryegrass system for phytoremediation, effectively enhancing soil quality and reducing the bioavailability of heavy metals. By demonstrating significant improvements in soil properties and heavy metal stabilization, this research provides a practical and environmentally friendly approach to soil remediation, offering new insights and methods for managing soil contamination.

description: Soil heavy metal contamination and sludge disposal have become globally environmental issues problems of great concern. Utilizing sludge pyrolysis to produce biochar for remediating heavy metal-contaminated soil is an effective strategy to solve these two environmental problems. In this study, municipal sewage sludge and papermaking sludge were used as feedstock to prepare co-pyrolyzed biochar, which was then applied to reduce the toxicity of Cd in soil. The results indicated that the application of co-pyrolyzed biochar significantly increased soil pH, CEC, and enzyme activity, while decreasing the content of available Cd in the soil. Following the application of 3% co-pyrolyzed biochar, the proportion of acid-soluble Cd in the soil decreased to below 46%, as the biochar facilitated the conversion of leachable acid-soluble Cd to stable oxidizable and residual forms through precipitation and complexation. The DFT computational results indicate that the aromatics in co-pyrolyzed biochar can adsorb Cd ions through cation-π interactions, while carboxyl, hydroxyl, aldehyde, and amide groups can provide more electrons for the adsorption of Cd ions, resulting in stronger adsorption capacities. The study findings provide a feasible solution for the resourceful treatment of sludge and the remediation of heavy metal-contaminated soil. This study is the first to investigate the remediation potential of municipal sludge and papermaking sludge co-pyrolyzed biochar for Cd-contaminated soil. Additionally, density functional theory (DFT) calculations were employed to elucidate the microscopic adsorption mechanisms of Cd ions by the co-pyrolysis biochar. These findings provide a theoretical foundation for the resource utilization of sludge and the development of cost-effective soil remediation agents.

description: Arabidopsis halleri ssp. gemmifera is well known as a Cd hyperaccumulator. Yet, understanding how this plant survives in a high Cd environment without appearing toxicity signs is far from complete. Therefore, this study emphasized on high level of Cd to be applied to evaluate Cd detoxification and tolerance strategies in the hyperaccumulator A. halleri ssp. gemmifera. The results showed that under 300 µM of Cd exposure in a hydroponic system for 56 days, Cd tends to be transported to the stem and leaves. The availability of more than 60% of Cd mobile fractions supported Cd translocation to leaves. EPMA at the cellular level identified Cd localization at the rim of leaf cells that might be associated with the Cd-cell wall form. The Cd soluble fraction in the leaves was found as Cd-free ion and Cd-complexed compound. Interestingly, this plant can still grow despite some inhibition, such as significantly decreasing total chlorophyll and anthocyanins content in the leaves. It was predicted that Cd-free ions were sequestered into the vacuole of leaves cells, by complexing it into organic acid compounds. Therefore, tolerance strategies in A. halleri ssp. gemmifera at high Cd is proved to be associated to compartmentalization and complexation strategies. The study examined how Arabidopsis halleri ssp. gemmifera, a Cd hyperaccumulator, responds to high levels of Cd exposure both at the organ and subcellular level. Our analysis revealed that Cd was primarily stored in leaves in the leaf rim, as confirmed by spatial imaging EPMA analysis. Furthermore, we found that Cd existed in the soluble fraction equally in two forms: as a Cd-free ion and as a Cd complexed with organic compounds. The study has successfully proved that compartmentalization and complexation are pivotal in the tolerance mechanisms of the hyperaccumulator Arabidopsis halleri ssp. gemmifera.
