Mineral Composition of Various Extracts and Essential Oil of Pickled Ferula orientalis L

: Edible wild plants are important food sources of the increasing world population and contribute to the healthy functioning of the body. Some of the edible wild plants, which are considered among the favourite flavours and consumed with pleasure in many countries, are rich in trace elements that play an effective role in the fight against various diseases. Ferula , a genus of edible wild plants in the Apiaceae family, is also known worldwide for its aromatic composition and medicinal properties. In this study, the essential oil of F. orientalis obtained by hydrodistillation and water, ethanol: water, methanol: water, chloroform, and n-hexane extracts prepared by classical and ultrasonic were studied. According to the mineral composition data determined by the Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), the essential oil was found to contain only sodium, potassium, manganese, and aluminum, among the 18 elements scanned. The most common elements found in the extracts were potassium, sodium, and phosphorus, and their amounts varied between 982.504- 42 282.486 ppm, 3267.141- 39 103.835 ppm, and 1898.652- 9280.814 ppm, respectively. According to the results, the ultrasound process significantly increased the mineral transfer to the extracts ( p < 0.01).
Effects of different broiler flooring systems on surface temperature, air quality and carcass characters of broilers

The present study investigated the use of perforated plastic floors with different heights in the broiler performance, surface temperature, air quality, and carcass characters of broilers. Three hundred sixty-seven day-old unsexed chicks randomly divided into 4 groups: control reared on sawdust litter in others used, plastic floors with different heights (5, 10 and 15) cm, for 2nd, 3rd and 4th treatment respectively. The first treatment (sawdust) showed significantly (P < 0.05) increase in body surface temperature, as compared to the plastic floors system treatments, and the three plastic floor treatments affected air quality, with less concentrations of ammonia and carbon dioxide compared to the sawdust. The results showed significant differences (P < 0.05) in the live relative weight, where the treatments T2, T3 and T4 were increase at the age of 35 days compared to the sawdust treatment. We suggested the perforated plastic floors could be a good alternative to promote a better quality environment and superior production rates with improved surface temperature.
Activation Network Localization of Facial Emotion Processing

Facial emotion processing is a basic psychological function of the human brain. Functional neuroimaging techniques have been widely used to probe its neural substrates in healthy subjects. However, like many other psychological functions, functional activations during facial emotion processing have been reported throughout the brain, and the findings are largely inconsistent across studies. Here, we attempted to test whether heterogeneous functional neuroimaging findings of facial emotion processing localized to a connected network and whether network localization could partly explain the poor reproducibility observed. First, using the activation likelihood estimation (ALE) meta-analysis technique, we showed that individual-brain-based reproducibility was low across studies. Then, using a new technique termed ‘activation network mapping’, which was adapted from lesion network mapping, we found that network-based reproducibility across these same studies was rather high; also, these seemingly heterogeneous functional neuroimaging findings mainly localized to a common brain network. Finally, our localized network based on activation matched brain stimulation locations—and the network derived from it—that disrupted facial emotion processing. It also aligned well with structural abnormalities in alexithymia—a disorder characterized by a deficiency in the ability to identify emotions, and brain lesions that disrupt facial emotion processing. Our results suggest that heterogeneous functional neuroimaging findings of facial emotion processing in healthy people localize to a common connected network, which improves the seemingly poor reproducibility among functional neuroimaging studies. Activation network mapping may prove to be a novel network-based technique that is potentially broadly applicable to localize brain networks of cognitive functions based on brain activations in healthy individuals.
Accuracy electroencephalography classification by a regularized long short-term memory network

The motor-based brain–computer interface is widely used in the exoskeleton reconstruction of patients with muscle weakness and to enhance the operating experience of somatosensory game customers through the combination of actions and electroencephalography signals. However, the recognition algorithms in traditional motor-based brain–computer interfaces have problems such as “brain–computer interface blindness” (recognition accuracy is less than 70%) and “one person one model. ” In this study, a regularized long short-term memory algorithm and a hardware platform for gesture recognition by using the motor-based brain–computer interface are proposed. Experimental results show that the gesture recognition accuracy rate based on the motor brain–computer interface is up to 95.69%, which is significantly better than that of other algorithms. The proposed model enhances the applicability and generalization ability of the brain–computer interface, for which the practicability and effectiveness are verified.
Lattice dynamics and ultrafast energy flow between electrons, spins, and phonons in a 3d ferromagnet

The ultrafast dynamics of magnetic order in a ferromagnet are governed by the interplay between electronic, magnetic and lattice degrees of freedom. In order to obtain a microscopic understanding of ultrafast demagnetization, information on the response of all three subsystems is required. A consistent description of demagnetization and microscopic energy flow, however, is still missing. Here, we combine a femtosecond electron diffraction study of the ultrafast lattice response of nickel to laser excitation with ab initio calculations of the electron-phonon interaction and energy-conserving atomistic spin dynamics simulations. Our model is in agreement with the observed lattice dynamics and previously reported electron and magnetization dynamics. Our approach reveals that the spin system is the dominating heat sink in the initial few hundreds of femtoseconds and implies a transient non-thermal state of the spins. Our results provide a clear picture of the microscopic energy flow between electronic, magnetic and lattice degrees of freedom on ultrafast timescales and constitute a foundation for theoretical descriptions of demagnetization that are consistent with the dynamics of all three subsystems.
Study on modification and failure of precast solid electrolyte interface film on Li metal anodes

Lithium (Li) metal anodes can be inevitably corroded and destructed due to the direct contact with the liquid electrolyte. Here, a precast solid electrolyte interface (SEI) film is constructed based on poly(vinylidene‐co‐hexafluoropropylene) (PVDF‐HFP) matrix on a copper current collector to avoid side reactions between Li and electrolytes and further prevent dendrites growth. Lithium bis(oxalato)borate (LiBOB), SiC, and polyethylene oxide (PEO) are rationally hybridized, and their effects on the morphology, composition, strength, and other properties of the precast SEI film are studied through both physical and electrochemical characterizations. Due to the addition of LiBOB, SiC, and PEO, the structure and properties of the PVDF–HFP matrix have undergone a distinct change, which affects the cycle stability of the substrate. As a result, the cycling lifetime of the SEI film is increased from 61 to 295 cycles after adding an appropriate amount of LiBOB to the PVDF–HFP. Furthermore, the Li metal anode delivers a significantly improved life‐span of 452 cycles at 1.0 mA·cm−2, 1.0 mAh·cm−2 by virtue of the robust SEI with SiC and PEO added. Meantime, the Coulombic efficiency of the cell has also increased from 95.0% to more than 99.0%. The morphology and composition characterization results show that the SEI structure gradually collapses during cycling, which are found to arise from the formation of loosely connected Li2CO3, LiF, and dilapidated PVDF–HFP mixture. The deteriorative artificial SEI also induces the disconnected electrical contact, and as such the impedance significantly increases, resulting in eventual failure of the Li metal anode.
Colour Transformation and Textural Change in Biotite: Some Remarks for the Interpretation of Firing Technology in Greyware Pottery Thin-Sections

Firing is a crucial step in the production of pottery, as it irreversibly transforms the clay into ceramic. Clay sintering and subsequent vitrification occur during firing, together with other transformations undergone by specific minerals and rock inclusions according to their optical and physical properties, including their colour. Some of these are visible in thin-sections and might be interpreted as technological markers or contribute to the estimation of firing temperatures, although most of them are poorly documented. In this paper, we approach the transformations in colour, texture and optical properties that occurred in biotite inclusions from medieval greyware pottery. Our study considers a batch of 40 pottery samples from medieval Catalonia analysed by XRD. According to the estimated firing temperature ranges and atmospheres, we examined the behaviour of biotite at different temperature ranges from 700 °C to 1000 °C by means of optical microscopy, considering its size, shape and abundance, and compared these features to a wider assemblage of thin-sections from medieval earthenware. The results obtained are interesting, as they offer a valuable reference for petrographic studies on pottery. We discuss the potential of ceramic petrography as a way to perform more precise and refined sample selection for further analysis on archaeothermometry.
Role of Superoxide Dismutases (SODs) in Hypertensive Rats After Administration of Mango Mistletoe Methanolic Extract

Hypertension is a condition where there is an abnormal rise in blood pressure that may be the primary cause of cardiovascular disease. Hypertension induces the production of free radicals known as reactive oxygen species (ROS) and oxidative stress. The purpose of this study is to further examine the function of Dendropthoe pentandra as an endogenous antioxidant modulator in this case superoxide dismutase (SOD) in hypertensive rats.The testing approach used is experimental. Data were analyzed using the one-way ANOVA test and the Post Hoc test to see variations in SOD levels in different treatments. This research used a hypertensive rat model induced by deoxycorticosterone acetate (DOCA) and salt. The number of animals tested was 25 white male rats divided into 5 groups, each containing 5 rats.The group consisted of a control group, a group of non- Extract methanolic of mango mistletoe hypertensive rats, and three groups of hypertensive rats receiving mango mistletoe methanolic extract (EMBM) at dosages of 50 mg/kg, 100 mg/kg, and 200 mg/kg body weight. Based on the results of the study, it is known that the levels of increased lung SOD with extract methanolic of mango mistletoe dosage variations in all treatment groups were not different. The administration of mango parasite methanolic extract at a dose of 50 mg / kgBW was optimum in increasing lung SOD levels in hypertensive rats.
Image-Guided Endoscopic Sinus Surgery with 3D Volumetric Visualization of the Nasal Cavity and Paranasal Sinuses: A Clinical Comparative Study

(1) Background: The purpose of this study was to develop an image-guided endoscopic sinus surgery (IGESS) system, named Medigator®, based on the leave-one-out registration strategy and three-dimensional (3D) volumetric visualization of the nasal cavity and paranasal sinuses. (2) Methods: A phantom was designed and fabricated using a 3D printer. We then performed a phantom-based accuracy evaluation to validate the performance of the developed registration method. We included 11 patients who underwent IGESS for clinical study to compare the performance of the developed IGESS system with that of a commercialized system. (3) Results: The fiducial registration error (FRE) was 0.14 mm, and the target registration error (TRE) was 0.82 ± 0.50 mm by the phantom-based evaluation. As a result of the clinical comparative study, the average registration times were 36.04 ± 4.7 and 89.35 ± 26.1 s for the developed and commercialized systems, respectively (p < 0.05). The image loading time of the developed system was also shorter than that of the commercialized system (p < 0.05). The average accuracy score of the developed system was not significantly different from that of the commercialized system (p > 0.05). (4) Conclusions: The developed system provided an accurate point-to-point registration method based on the leave-one-out strategy. According to the results of the clinical comparative study, we demonstrated that the developed system showed reliable potential for clinical application.
A Study to Resist Conduced Interference from GIS Bus-Charging Currents Switching for Electronic Current Transformer

In this paper, we study the conducted interference to an electronic current transformer introduced in the process of bus-charging currents which are caused by switching a gas insulated switchgear (GIS) disconnector. To cope with these issues, the EMTP-ATP and Matlab/Simulink software are used to carry out equivalent modeling simulations and experimental research, respectively. More specifically, the very fast transient current generated by disconnector switching (DS) is used as the input source of the equivalent simulation model of the Rogowski coil, and the characteristics of conducted interference waveforms of the Rogowski coil, the active integrator and filter outputs under single and multiple breakdowns are analyzed step by step. Moreover, several anti-interference methods are proposed to improve the resistance to the high-voltage and high-frequency conducted interference for the Rogowski coil, such as reducing the Rogowski cut-off frequency, increasing the transient voltage suppressor (TVS), active filter, and Cy capacitor. Besides, the study also reveals that the residual charge of the integral capacitor will discharge with a time constant τ = 1 s after arc quenching with the first-order discharge circuit, which is composed of the feedback resistance and the integral capacitor C. Lastly, the experimental results demonstrate the correctness of the modeling method proposed in this paper and the effectiveness of anti-interference measures.
The total solar eclipse of December 14, 2020 in southern South America and its effects on atmospheric variables

A total solar eclipse affected southern South America on December 14, 2020. Its occurrence close to the summer solstice in the Southern Hemisphere and around noon brought almost ideal conditions to study the effects of the sudden reduction in incoming solar radiation on different atmospheric variables. Interestingly, the astronomical phenomenon moved over a region that at that time was being affected by a cold front accompanied by significant cloudiness and cold air advection to the area. Therefore, the actual drop in surface temperature over the umbra region resulted from a combination of the radiative effect (i.e., the reduction in solar radiation due to the eclipse itself) and a circulation effect related to the injection of colder air. A quantification of both effects on the full temperature variation is provided, along with a discussion on the underlying mechanisms and the related effects on surface winds derived from the cooling. Results show that temperature drops associated with total solar eclipses in areas far away from the umbra can be as high as (or even higher than) those within the umbra, depending on the prevailing weather conditions.
Transformation of Urbanozems in the Areas of Gas Stations

The areas near gas stations are places of local specific environmental pollution. The purpose of this work was to study the environmental consequences of gas station functioning on the surrounding soils (urbanozems). The content of oil products (OP), bulk and mobile forms of heavy metals, acute toxicity (Ceriodaphnia affinis Lillieborg, Раramecium caudatum Ehrenberg, Escherichia coli Migula), chronic toxicity (C. affinis), and the state of soil microphotrophs were determined. The content of OP was from 520±130 to 4820±100 mg/kg, which is significantly higher than the concentrations of OP in the soils of the transport zone of cities. The exceeding of the Russian standards for HM was found only for zinc (the maximum for the total form – 1.7 MPC, for the mobile form – 1.4 MPC). The urbanozems samples did not have acute toxicity; however, chronic toxicity in the bioassay for the mortality of C. affinis (up to 85%) and a decrease in the fertility of crustaceans (2–3 times compared to the control) were observed. In the structure of the community of soil microphototrophs, cyanobacteria dominated both in biomass and in abundance: (up to 748±10 thousand cells/1 g of soil) compared with green algae and diatoms (1.1–5.5 and 1.2–19.8 thousand cells/1 g of soil, respectively). As a result of the work, it was concluded that the quantitative algological analysis and biotest with the assessment of chronic toxicity in terms of mortality and fertility of C affinis for the diagnosis of local soil contamination in the areas of gas stations were of the highest informative value.
Analysis of multiplanar integration based on uncertainty estimation in automatic segmentation of abdominal organs in 3D CT image using 2D Bayesian U-Net

Recently, it has been shown that the uncertainty can be estimated by integrating Monte Carlo (MC) dropout [1] in the neural network structure in deep learning. Our group proposed Bayesian U-Net [2], which integrates MC dropout with U-Net [3] architecture, and investigated the relationship between the segmentation accuracy (Dice) and the uncertainty inferred by MC dropout. High correlation between the uncertainty and the errors in the automatic segmentation of musculoskeletal structures in CT images was obtained. In a different study, the integration of the segmentations obtained by voting based on prediction probabilities by convolutional neural networks (CNNs) trained for each anatomical plane independently [4] could further improve the segmentation accuracy and reduced the calculation time. However, as far as we know, the uncertainty-based integration has not been investigated yet. In this paper, we applied 3 Bayesian U-Nets, each trained on 2D slices in one of the three anatomical planes, to two-phase contrast-enhanced CT images of 48 cases (97 images) with manual segmentation of 17 organs. We report the variations in the uncertainties with respect to the anatomical planes, and finally evaluate the multiplanar integration-based predictions compared with single plane-based predictions. The segmentation accuracy, represented by Dice coefficient (DC), was significantly improved by the uncertainty-based integration in 9 organs (p<0.05) compared with segmentations obtained only from the axial plane. All segmentation results showed a negative correlation between the uncertainty and DC. We found that the segmentation accuracy could be improved by integrating the multiplanar segmentation results based on uncertainty estimation.
Lutar, esconder ou correr: como Tamandua tetradactyla (Mammalia) em cativeiro responde a pistas indiretas de um predador?

In the natural environment, animals are exposed to a wide number of threats to survival. Considering the ecology of fear is important to estimate the ecosystem role that predators play in animal communities, since fear of a predator can cause not only density-based responses (e.g., removal of individuals from a population), but also behavioural responses, which can result in cascading effects. Defensive behaviours are relatively simple to assess in captivity, since they are conspicuous and specific, and also difficult to be confused with other behaviours when observed. Thus, the aim of this study was to verify the ability of individuals of Tamandua tetradactyla (Linnaeus, 1758) in captivity to detect indirect clues of a natural predator. In this study, we exposed six individuals of lesser anteaters (T. tetradactyla) in captivity, to indirect clues (e.g., urine and feces) of ocelot (Leopardus pardalis). In total, we observed five males and one lesser anteater female by the focal animal method, in a total effort of 36 hours of observation. Lesser anteaters located in enclosures with indirect predator tracks exhibited a higher frequency of anti-predatory behaviours and a decrease in inactivity behaviours. The use of indirect clues is advantageous for lesser anteater’s individuals, as they allow the risk assessment of a particular spot in the environment and elicits avoidance behaviours, which are less costly in energy. We also present the percentage of behaviours of T. tetradactyla with and without the indirect clues of the predator that can be useful to understand the ability of lesser anteaters to respond to situations of danger.
Determination of dopamine in the presence of ascorbic and uric acids by fluorometric method using graphene quantum dots

ABSTRACT Graphene quantum dots were synthesized by control carbonization of citric acid and utilized for selective determination of dopamine in the presence of ascorbic and uric acids. The prepared graphene quantum dots were characterized by X-ray diffraction, transmission electron microscopy, and Fourier transform infrared, ultraviolet–visible and fluorescence spectroscopy. The results revealed that dopamine could quench the fluorescence of graphene quantum dots through a dynamic quenching mechanism. Under the optimized conditions, the linear concentration range was obtained within 0.01–50.0 µM, with the correlation coefficient of 0.9983 and a limit of detection of 8.2 nM. This method does not show any interference with respect to coexisting foreign substances, even at the presence of 500-fold of ascorbic acid and uric acid.
