description: A new approach was developed to disperse "electroactive" Sn into an "inactive" matrix for application as negative electrode for the electrochemical storage energy. The [Sn(BPO4)xCy] composite material was obtained by carbothermal reduction of SnO2 into a BPO4 matrix. The condition of synthesis was optimized using DSC-TGA analysis. This composite material was characterized by X-ray diffraction, Scanning Electron Microscopy, 119Sn Mössbauer spectroscopy and electrochemical tests. The results show these new materials present very interesting electrochemical performances; the discharge capacity for the first cycle was 650mAh.g-1 and the reversible capacity was 500 mAh.g-1 at C/5 rate. These improved electrochemical results are due to good in situ dispersion of Sn particles into the matrix. The irreversible capacity observed for the first charge/discharge cycle is due to interfacial SnII reduction and passivation of the anode surface by liquid electrolyte decomposition (SEI layer)

description: The structure and kinematics of the old component of the Galactic bulge are still a matter of debate. The bulk of the bulge as traced by red clump stars includes two main components, which are usually identified as the metal-rich and metal-poor components. They have different shapes, kinematics, mean metallicities, and alpha-element abundances. It is our current understanding that they are associated with a bar and a spheroid, respectively. On the other hand, RR Lyrae variables trace the oldest population of the bulge. While it would be natural to think that they follow the structure and kinematics of the metal-poor component, the data analysed in the literature show conflicting results. We aim to derive a rotation curve for bulge RR Lyrae stars in order to determine that the old component traced by these stars is distinct from the two main components observed in the Galactic bulge. This paper combines APOGEE-2S spectra with OGLE-IV light curves, near-IR photometry, and proper motions from the VISTA Variables in the Vía Láctea survey for 4197 RR Lyrae stars. Six-dimensional phase-space coordinates were used to calculate orbits within an updated Galactic potential and to isolate the stars. The stars that stay confined within the bulge represent 57% of our sample. Our results show that bulge RR Lyrae variables rotate more slowly than metal-rich red clump stars and have a lower velocity dispersion. Their kinematics is compatible with them being the low-metallicity tail of the metal-poor component. We confirm that a rather large fraction of halo RR Lyrae stars pass by the bulge within their orbits, increasing the velocity dispersion. A proper orbital analysis is therefore critical to isolate bona fide bulge variables. Finally, bulge RR Lyrae seem to trace a spheroidal component, although the current data do now allow us to reach a firm conclusion about the spatial distribution.

description: We determine the influence of the Milky Way's warp on the kinematics of stars across the disc, and therefore measure its precession rate and line of nodes under different assumptions. We do this by applying Jeans' first equation to a model of a rigidly precessing warp. The predictions of these models are fit to the average vertical velocities of stars with measured line-of-sight velocities in Gaia DR3 data. We test models in which the warp's line of nodes and precession speed are fixed, and models in which they are allowed to vary linearly with radius. We also test models in which the velocity of stars radially in the disc is included in Jeans' equation. The kinematic data is best fit by models with a line of nodes that is 40 degrees offset from the Sun's Galactic azimuth, significantly leading the line of nodes found from the positions of stars. These models have a warp precession speed of around 13 km/s/kpc in the direction of Galactic rotation, close to other recent estimates. We find that including the velocity of stars radially in the disc in our kinematic model leads to a significantly worse fit to the data, and implausible warp parameters. We conclude that the Milky Way's warp appears to be rapidly precessing, but the structure and kinematics of the warped disc are not consistent within the approximation of a fixed, precessing, warp shape. This implies that the Milky Way's warp is dynamically evolving, which is a challenge to models of the warp's creation, and must be considered in the context of other known disturbances of the disc.

description: Die vorliegende Arbeit verfolgt das Ziel, die Beratung von Fachpersonen der Soziokulturellen Animation (SKA) im offenen Setting am Beispiel der Offenen Jugendarbeit (OJA) sichtbar zu machen und den fachlichen Diskurs darüber zu fördern. Diesen Situationen wird in der Theorie wenig Beachtung geschenkt, sie finden in der OJA jedoch häufig statt. Es werden relevante Bezüge zur allgemeinen Beratungsliteratur aufgezeigt und mit den theoretischen Grundlagen der SKA und der OJA verknüpft. Dass hierbei Parallelen in Bereichen wie Partizipation, Offenheit und Freiwilligkeit sichtbar werden, verdeutlicht das Potenzial, welches diese Beratungsform hat und bietet gleichzeitig die Legitimationsgrundlage.

Mittels qualitativer Forschung wird den Fragen nachgegangen, wie die Beratungssituationen im offenen Setting entstehen und welche Faktoren sie beeinflussen. Die Ergebnisse zeigen, dass drei Entstehungsarten existieren: (1) Die Fachperson wird angesprochen, (2) die Fachperson initiiert ein Gesprächsangebot und (3) eine unerwartete Gesprächsentwicklung führt zu einer Beratung. Die Aspekte Beziehung, Niederschwelligkeit, Partizipation, Lebensweltorientierung, Ressourcen, Kommunikation und Gesprächsführung sowie Persönlichkeit der Fachperson als Einflussfaktoren auf die Entstehung von Beratungssituationen werden erläutert und diskutiert.

Aufgrund der Ergebnisse wird Potenzial darin gesehen, dass Fachpersonen der SKA einen einheitlichen Begriff für Beratungen im offenen Setting verwenden. Daher wird als Definitionsversuch die Bezeichnung soziokulturelle Beratung vorgeschlagen. Abschliessend werden weitere Handlungsempfehlungen auf Ebene der Profession, Institution sowie Praxis aufgezeigt.

description: This work focuses on Cr(VI) sorption by Calcareous and nZVI/Calcareous was investigated. The purpose of this study is to understand the mechanisms that govern the elimination of Cr (VI) and to find a suitable kinetics model of removal. Spectroscopic studies including FTIR, (TG-DSC), SEM, Methylene blue and Iodine number were used for its characterization. Equilibrium data was examined using a comparison of linear Langmuir, Freundlich, Temkin and Dubinin–Radushkevich isotherm models. The Freundlich isotherm provided the best fit to the experimental data for Cr(VI) ions as indicated by the values of the regression coefficient. The kinetic rates were modeled by using the Lagergren-first-order, pseudo-second-order, Elovich and Intraparticle diffusion model. The Elovich model was found to explain the adsorption kinetics most effectively. The presence of intra-particle diffusion mechanism was prominent, although it was not the sole rate-determining step. The results showed that Calcareous and nZVI/Calcareous, can be effective for removing Cr(VI) ions from solution.

The Effect of Tourniquet Reperfusion Interval on MDA Levels and Skeletal Muscle Damage in the Treatment of Long Bone Fractures
Creators: name: Utomo, Adhi Satriyo
name: Huwae, Thomas Erwin Christian Junus
Publisher: name: Zenodo
Year: 2025

description: Background: Tourniquets are often used to assist hemostasis during surgery, even if they cause complications. Blood circulation return leads to ischemic reperfusion injury. Post-tourniquet syndromes, such as pain, swelling, and muscle weakness, occur up to six weeks after surgery. Thus, it is necessary to investigate the duration of reperfusion intervals to prevent ischemic reperfusion injury, specifically to muscle tissue.

Method: An experimental study using 48 male white rats (Rattus norvegicus) deliberately fractured in the tibial bone. The rats were divided into two treatment groups, A and B, each receiving four treatments. So, there were eight groups in total. In the control group, both A1 and B1, the tourniquet was installed using orthodontic rubber for 3 hours, while for the others for 2 hours, it was deflated for 5, 10, and 15 minutes, respectively, then the tourniquet was reattached for 1 hour. Group A was sacrificed 1 hour after tourniquet deflation and then checked for MDA levels and muscle histology. In group B, it was done on day 14. Data results were analyzed using one-way ANOVA.

Result: In group A, there was a significant difference between the ten and 15-minute groups. In group B, there was a significant difference between groups; the optimal decrease in PI occurred in the 10-minute reperfusion interval treatment, which was 42.63% for group A and 32.27 % for group B. Significant differences existed between the control and reperfusion interval groups in measuring MDA levels in groups A and B.

Conclusion: The reperfusion interval can reduce the incidence of ischemic reperfusion injury in the muscle organ at the distal tourniquet, characterized by MDA levels and a percentage of muscle tissue injury. The 10-minute reperfusion interval is the most effective in restoring aerobic metabolism and preventing excessive ROS production.

description: The dependence of stellar magnetic activity on stellar parameters would be inspired by the chromospheric activity studies based on the large-scale spectroscopic surveys. The Ca II H and K lines are employed to construct indicators for assessing and studying the chromospheric activity of solar-like stars. We investigate the widely used bolometric and photospheric calibrated chromospheric activity index $R'_{\rm HK}$, derived from the method in the classic literature ($R'_{\rm HK,classic}$) and the method based on the PHOENIX model ($R'_{\rm HK,PHOENIX}$). Since the detailed stellar atmospheric parameters, effective temperature ($T_{\rm eff}$), surface gravity ($\log\,g$), and metallicity ([Fe/H]), are available for LAMOST, we estimate the chromospheric activity index $R'_{\rm HK,PHOENIX}$, along with the corresponding bolometric calibrated index $R_{\rm HK,PHOENIX}$, taking these parameters into account. We provide the database of the derived chromospheric activity parameters for 1,122,495 LAMOST LRS spectra of solar-like stars. Our calculations show that $\log\,R'_{\rm HK,PHOENIX}$ is approximately linearly correlated with $\log\,R'_{\rm HK,classic}$. The results based on our extensive archive support the view that the dynamo mechanism of solar-like stars is generally consistent with the Sun; and the value of solar chromospheric activity index is located at the midpoint of the solar-like star sample. We further investigate the proportions of solar-like stars with different chromospheric activity levels (very active, active, inactive and very inactive). The investigation indicates that the occurrence rate of high levels of chromospheric activity is lower among the stars with effective temperatures between $5600$ and $5900 \,{\rm K}$.

description: In this work an unsaturated polyester resin (UPR) containing porcelain powder prepared from ceramic waste were fabricated and subjected to various studies. The mechanical properties, thermal stability, and water absorption resistance of the UPR and composites prepared for each condition were evaluated. Results show that porcelain powder based composite found to have superior properties than that of unsaturated polyester resin in overall investigated properties. All the materials show a lesser amount of water absorption in short time immersion and the highest stability in water. Thermal degradation indicated that the composite is more resistant to temperature than unsaturated polyester matrix due to the effect of porcelain powder incorporated. The results of this work show that it is possible to use this type of ceramic waste in unsaturated polyester resin for preparation for new materials destined to domestic use

description: Adsorption of Hg(II) and Zn(II) ions from a binary solution was examined using activated carbons (ACs) prepared from a lowland bioresource waste (Theobroma cacao pod husk). The aim of the study was to determine the potential for utilizing the plant-based ACs as a low-cost adsorbent for removing the metal ions from a binary. Batch adsorption experimentations were conducted to evaluate the initial metal ion concentration and contact time on adsorption. Spectroscopic studies including FTIR, elemental analysis (EA) and SEM were used for its characterization. Equilibrium data was examined using a comparison of linear Langmuir, Freundlich and Temkin isotherm models. The Langmuir and Temkin isotherm model provided the best fit to the experimental data for both metal ions as indicated by the values of the regression coefficient. The kinetic rates were modeled by using the Lagergren-first-order, pseudo-second-order, Elovich and Intraparticle model. The pseudo-first order, pseudo-second order equations and Elovich equation gave the best fit to the experimental data. The presence of intra-particle diffusion mechanism was prominent, although it was not the sole rate-determining step. The results showed that ACs can be effective for removing Hg(II) and Zn(II) ions from solution.

description: Accretion bursts from low-mass young stellar objects (YSOs) are known for many decades. In recent years, the first accretion bursts of massive YSOs (MYSOs) have been observed. These phases of intense protostellar growth are of particular importance for studying massive star formation. Bursts of MYSOs are accompanied by flares of Class II methanol masers (hereafter masers), caused by an increase in exciting mid-infrared (MIR) emission. The G323.46$-$0.08 (hereafter G323) event extends the small sample of known MYSO bursts. Maser observations of the MYSO G323 show evidence of a flare, which was presumed to be caused by an accretion burst. This should be verified with IR data. We used time-dependent radiative transfer (TDRT) to characterize the heating and cooling timescales for eruptive MYSOs and to infer the main burst parameters. The G323 accretion burst is confirmed. It reached its peak in late 2013/early 2014 with a Ks-band increase of 2.5mag. TDRT indicates that the duration of the thermal afterglow in the far-infrared (FIR) can exceed the burst duration by years. The latter was proved by SOFIA observations, which indicate a flux increase of $(14.2\pm4.6)$% at $70\, \rm μm$ and $(8.5\pm6.1)$% at $160\, μ$m in 2022 (2 years after the burst end). A one-sided light echo emerged that was propagating into the interstellar medium. The G323 burst is probably the most energetic MYSO burst observed so far. Within $8.4 \rm \, yrs$, an energy of $(0.9\pm_{0.8}^{2.5}) \times 10^{47}\,\rm erg$ was released. The short timescale points to the accretion of a compact body, while the burst energy corresponds to an accumulated mass of at least $(7\pm_{6}^{20})\,M_{Jup}$ and possibly even more if the protostar is bloated. In this case, the accretion event might have triggered protostellar pulsations, which give rise to the observed maser periodicity.

description: An iron rich soil resource containing 67% Fe2O3 that is inactive towards the discoloration of tartrazine (TA) at neutral pH was used to prepare composites with charcoal obtained from aniline. The Composites were obtained by heating this soil, aniline and sulphuric acid under air at 400°C and 600°C and the products (or catalyst) denoted as Cal400 and Cal600 respectively. Cal400 and Cal600 were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), X-ray Diffraction, X-ray Fluorescence and Nitrogen adsorption-Brunauer-Emmet-Teller (N2-BET). Their catalytic activities were monitored by discoloration of tartrazine yellow dye and were performed by varying catalyst load (0.065, 0.125, 0.250, 0.375 and 0.500 g/L), H2O2 concentration (8, 16, 24 mol/L) and pH (5, 7, 8).The influence of NaCl, Na2CO3 and NaHCO3 (1g/L) on the catalytic performance and the influence of initial pH on the iron leaching was also addressed. 94% of tartrazine was discolorated after 120 min of reaction with catalyst dose of 0.065 g/L; initial tartrazine concentration of 55 mg/L; H2O2 concentration of 8mM and initial pH = 7. Leaching test indicated that the leached iron from the catalyst was less than 5 mg L−1. Although all ions under study inhibited discoloration signiﬁcantly, the inhibition efﬁciency of Cl- is less than that of the others ions.

description: The objective of the present study is to investigate the spatiotemporal variation analysis of water quality and identification of water pollution sources in Oum Er Rbia river. To evaluate the water quality of river, physico-chemical analysis of water samples taken from eight stations in dry and in wet seasons along the Oum Er Rbia river were studied. These stations were monitored for 20 parameters; water temperature, pH, dissolved oxygen, electrical conductivity, total Hardness, turbidity, tomplete alkalimetric title, organic matter (oxidizability), chlorides, sulphates, nitrates, nitrites, ammonium, iron, copper, lead, cadmium, nickel, chromium, and zinc. Results of water samples were compared with Moroccan norms for drinking water and permitted values recommended by World Health Organization. Results indicated that the water quality parameters are over Moroccan norms for drinking water in some stations. Seasonal variation was observed in the physicochemical composition of water in the wet compared to the dry period. The water quality index (WQI) method was used to evaluate water quality classification for drinking purpose. This study indicates that the water of Oum Er Rbia River is potentially dangerous to health of the users and signaled the necessity to treat industrial and municipal wastewater and to encourage sustainable agricultural practices to avoid adverse health effects.

description: The purpose of the this study carried out at the Tiznit wastewater treatment plant (WWTP) is to evaluate the purification performance of the conventional stabilization ponds type process and, on the other hand, to improve the purification performance by using adsorption process based on novel inert natural materials of animal origin. This project is part of a sustainable development approach, aimed to improve the purification performance of WWTP by introducing low-cost, abundant and inexpensive solid inert biomaterials (SIBM). This adsorption process is recognized as one of the best water treatment techniques, more and more works are oriented towards the search for new materials, cheaper and having a good adsorbent potential. The results obtained with decanted raw wastewater (RWWD) and purified wastewater (PWW) are encouraging and show significant purification yields: 52 % and 48 % for sulfate ions and 43 % and 47 % for nitrate ions, respectively, for RWWD and PWW.

description: We investigate Klein-Gordon (KG) oscillators in a Gö% del-type Som-Raychaudhuri spacetime in a mixed magnetic field (given by the vector potential $A_{μ}=\left( 0,0,A_{φ},0\right) $, with $% A_{φ}=B_{1}r^{2}/2+B_{2}r$). The resulting KG equation takes a Schr% ödinger-like form (with an oscillator plus a linear plus a Coulomb-like interactions potential) that admits a solution in the form of biconfluent Heun functions/series $H_{B}\left( α,β,γ,δ,z\right) $% . The usual power series expansion of which is truncated to a polynomial of \ order $n_{r}+1=n\geq 1$ through the usual condition $γ=2\left( n_{r}+1\right) +α$. However, we use the very recent recipe suggested by Mustafa \cite{1.29} as an alternative parametric condition/correlation. i.e., $δ=-β\left( 2n_{r}+α+3\right) $, to facilitate conditional exact solvability of the problem. We discuss and report the effects of the mixed magnetic field as well as the effects of the Gödel-type SR-spacetime background on the KG-oscillators' spectroscopic structure.

description: Olives mill waste water resulting from the extraction of olive oil are the major problem of olive growing because of their polluting power (rich in organic and mineral matter) and their acid pH. The aim of this study is to treat these margins electrochemically in an aluminum electrode reactor, in order to oxidize the organic matter, discolour the margins, neutralize the pH and consequently reduce the pollutant power of this product. After this study, it was found that the increase in electrolysis time and the intensity of the current significantly improved the treatment. However, simultaneous energy consumption and electrodes were observed. The results of these analyzes showed that thirty-fold diluted margins are effluents at acid pH (5.02), Conductivity (14.89).The evolution of the physicochemical parameters during the electrocoagulation (EC) treatment shows that under the conditions of an electrolysis time of 3 h and a current intensity of 3A (corresponds to 416 A.m-2), the discoloration Of the margins diluted ten times is between 91%, the reduction of the lost mass of the electrodes is 0.55 kg.m-3 and the reduction of the COD is 50%. These optimal operational levels allow a good degradation of the effects of margins. The results have established good potentiality for the electrocoagulation to be used as a method for the removal of phenol from wastewater.

description: Due to their analytical tractability, random matrix ensembles serve as robust platforms for exploring exotic phenomena in systems that are computationally demanding. Building on a companion letter [arXiv:2312.17481], this paper investigates two random matrix ensembles tailored to capture the critical behavior of the Anderson transition in infinite dimension, employing both analytical techniques and extensive numerical simulations. Our study unveils two types of critical behaviors: logarithmic multifractality and critical localization. In contrast to conventional multifractality, the novel logarithmic multifractality features eigenstate moments scaling algebraically with the logarithm of the system size. Critical localization, characterized by eigenstate moments of order $q>1/2$ converging to a finite value indicating localization, exhibits characteristic logarithmic finite-size or time effects, consistent with the critical behavior observed in random regular and Erdös-Rényi graphs of effective infinite dimensionality. Using perturbative methods, we establish the existence of logarithmic multifractality and critical localization in our models. Furthermore, we explore the emergence of novel scaling behaviors in the time dynamics and spatial correlation functions. Our models provide a valuable framework for studying infinite-dimensional quantum disordered systems, and the universality of our findings enables broad applicability to systems with pronounced finite-size effects and slow dynamics, including the contentious many-body localization transition, akin to the Anderson transition in infinite dimension.

description: We construct the generalized $β$ and $(q,t)$-deformed partition functions through $W$ representations, where the expansions are respectively with respect to the generalized Jack and Macdonald polynomials labeled by $N$-tuple of Young diagrams. We find that there are the profound interrelations between our deformed partition functions and the $4d$ and $5d$ Nekrasov partition functions. Since the corresponding Nekrasov partition functions can be given by vertex operators, the remarkable connection between our $β$ and $(q,t)$-deformed $W$-operators and vertex operators is revealed in this paper. In addition, we investigate the higher Hamiltonians for the generalized Jack and Macdonald polynomials.

description: In this research, BaCO3/ZnO-Al2O3 nanocomposite photocatalyst at different amount of Ba (1, 3 and 5 wt%) was prepared from Zn-Al-CO3 layered double hydroxides precursors using ceramic process. A range of physicochemical techniques including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) with energy dispersive X-ray analysis (EDX), were employed to characterize the as-prepared catalysts. The photocatalytic activity of the catalysts was evaluated for the photocatalytic degradation of caffeine as a model of pharmaceutical pollutant in aqueous solutions under UV irradiation. Detailed photocatalytic experiments based on the effects of dopant amount, irradiation time, catalyst dose, initial pH and reuse were performed and presented in this study. The enhancement of photocatalytic activity was strongly dependent on the Ba amount and adsorption process. The 1%Ba/ZnO-Al2O3 sample with high adsorption capacity showed the highest photocatalytic activity with a degradation efficiency of 98.2% after 70 min of irradiation. It showed a significantly higher rate of degradation compared to undoped, pure ZnO and standard Degussa P-25 titanium dioxide. The photocatalyst showed high stability after three regeneration cycles

description: A melt-quenched method is used to prepare homogeneous glasses inside the 20Na2O-(50-x)Na2WO4-xTiO2-30P2O5 (0≤x≤25 mol%) system. The amorphous and glassy states of the glasses are evidenced by the X-Ray diffraction and differencial scanning calorimetry (DSC) analysis, respectively. The glasses were found to be colorless. Some physical parameters for the glasses such as density, molar volume and glass transition temperature (Tg) are determined and depended strongly on the chemical composition of the glasses. The density and Tg showed the decrease and the increase with TiO2 content, respectively. Infrared spectroscopy (IR) and Raman spectroscopy are used to characterize their structural approach. These both techniques have allowed the identification of different phosphate structural units mainly pyrophosphate and metaphosphate in their structure. From the absorption edge studies, the values of the optical band gap (Eg) and Urbach energy (DE) were evaluated. The optical band gap was found to depend on the glass composition and its value decreased as the content of the TiO2 increases. The sdc conductivity of the glasses is determined and it followed and Arrhenius behavior as a function of temperature. These electrical data are analyzed by the modulus formalism.

This species was originally described based on 3 females from Colombia. Subsequently, Hovore (1989) recorded it for Costa Rica, and Monné and Giesbert (1994) for Mexico (Veracruz). The holotype female (see photograph at Bezark 2019), and a paratype female were destroyed by the 2018 fire that devas- tated the MNRJ. According to the original description a third paratype female is deposited in Carleton University, Ottawa, Canada. The male of O. howdeni is illustrated (Fig. 6) and commented on for the first time here. It differs from the female by the longer antennae (2.15 times elytral length, reaching elytral apex at basal third of antennomere VII), and has the last abdominal ventrite flattened and not centrally sulcate. In the female, the antennae are 1.85 times elytral length, reaching elytral apex at basal third of antennomere VIII, and the last abdominal ventrite is convex with a shallow longitudinal, central sulcus in basal half.
