Benefits of simulating precipitation characteristics over Africa with a regionally-coupled atmosphere–ocean model

High-quality climate information at appropriate spatial and temporal resolution is essential to develop and provide tailored climate services for Africa. A common method to produce regional climate change data is to dynamically downscale global climate projections by means of regional climate models (RCMs). Deficiencies in the representation of the sea surface temperatures (SSTs) in earth system models (ESMs) and missing atmosphere–ocean interactions in RCMs contribute to the precipitation bias. This study analyzes the influence of the regional atmosphere–ocean coupling on simulated precipitation and its characteristics over Africa, and identifies those regions providing an added value using the regionally coupled atmosphere–ocean model ROM. For the analysis, the MPI-ESM-LR historical simulation and emission scenario RCP8.5 were dynamically downscaled with ROM at a spatial resolution of 0.22° × 0.22° for the whole African continent, including the tropical Atlantic and the Southwest Indian Ocean. The results show that reduced SST warm biases in both oceans lead to more realistic simulated precipitation over most coastal regions of Sub-Saharan Africa and over southern Africa to varying degrees depending on the season. In particular, the annual precipitation cycles over the coastal regions of the Atlantic Ocean are closer to observations. Moreover, total precipitation and extreme precipitation indices in the coupled historical simulation are significantly lower and more realistic compared to observations over the majority of the analyzed sub-regions. Finally, atmosphere–ocean coupling can amplify or attenuate climate change signals from precipitation indices or even change their sign in a regional climate projection.

Influence of pretesting and a near peer sharing real life experiences on CPR training outcomes in first year medical students: a non-randomized quasi-experimental study

BackgroundExisting literature on cardiopulmonary resuscitation (CPR) training focuses on the knowledge and skill components while the attitudinal component is rarely addressed. There is a need to explore how peer interaction, learning atmosphere, and communication influence learning effectiveness during CPR training. Therefore, this study’s objective was to evaluate how a senior student (near peer) sharing their real-life experience of performing CPR would influence medical students’ learning and readiness to perform CPR.MethodsThe present study involved 250 newly enrolled undergraduate medical students. The Solomon’s four-group study design was used to evaluate the influence of both pretesting and peer interaction. Students belonging to two groups initially completed a pre-training knowledge test (pretest) and a questionnaire on readiness to perform CPR. Students from all four groups then participated in instructor-led hands-on skills training, after which the two intervention groups interacted with their senior, who shared their life experiences of performing CPR. Finally, all four groups underwent skills evaluation, immediate and delayed post-tests, and completed a questionnaire to assess readiness to perform CPR. The students also provided their feedback on the experience of interacting with a peer during the training.ResultsPost-test scores were significantly higher than pretest scores (Kruskal–Wallis test, p < 0.05). Scores were significantly higher in pretested intervention groups than in the non-pretested non-intervention group (p < 0.05). Delayed post-test scores were slightly but not significantly lower than the immediate post-test scores with no significant difference observed in the scores among the groups. The pretested groups showed more readiness to perform CPR and the pretested intervention group were least concerned about acquiring infection during CPR. Students in all groups were confident of performing chest compressions correctly, and found it inspiring and motivating listening to and discussing real-life experiences with a near peer.ConclusionsHearing from peers about real-life CPR experience during CPR training sessions significantly impacted learning, enhanced student motivation to learn and may be an effective strategy to consider in routine CPR training. However, the positive effects of pretesting and peer interaction on knowledge were not sustained, highlighting a need for repeat training.

Abstract On March 5 of 1991, Kurdish people in the North part of Iraq launched an uprising which resulted in reoccupying various lands from the hands of socialist groups and Baath Regime. These lands were taken over by the demonstrators and revolutionists. This revolution resulted in the establishment of an autonomous Kurdish government. Additionally, Soran province as a part of those reoccupied lands, fell under the influence of that revolutionary atmosphere. As various social activists and artists began seizing the opportunity and started making groups in order to make artistic activities. Moreover, before the revolution of 1991, theatre influenced a large number of people. And these people started constructing different theatrical teams and acting performers in order to be engaged in that art. Although, it is said that there were theatrical and artistic groups in soran province. Yet, non of their names or their participant's names had ever been mentioned in the documentations. Therefore, researchers have tried to recognize and pinpoint these theatrical groups between the years 1991_2003 in soran and also to highlight their characteristics and principles.

Comparative catalytic study on butene/isobutane alkylation over LaX and CeX zeolites: The influence of calcination atmosphere

Lanthanum-containing (LaX) and cerium-containing X zeolites (CeX) were prepared by a double-exchange, double-calcination method. By changing the calcination atmospheres between nitrogen and air, the CeIV contents in CeX zeolites were adjusted and their impacts on physicochemical properties and catalytic performance in isobutane alkylation were established. The crystallinity of CeX zeolite was found to be negatively correlated with the CeIV content. This i s believed to be due to the water formed during the oxidation of CeIII, which facilitates the framework dealumination. As a consequence, calcining in air resulted in a great elimination of strong Brønsted acid sites while under nitrogen protection, this phenomenon was mostly hindered and the sample's acidity was preserved. When tested in a continuously flowed slurry reactor, the catalyst lifetime for isobutane alkylation was found to be linearly related to the strong Brønsted acid concentration. In addition, Ce3+ was found more benefit for the hydride transfer compared with La3+, which is ascribed to the stronger polarization effect on the CH bond of isobutane. Moreover, the decline of hydride transfer activity can be slowed down by the catalytic cracking of the bulky molecules. Based on the product distribution, a new catalytic cycle of dimethylhexanes (DMHs) involving a direct formation of isobutene rather than tert-butyl carbocation was proposed in isobutane alkylation.

The effects of annealing atmosphere and intrinsic component on high temperature evolution behaviors of SiC fibers

In this work, the second (F1) and third (F2) generation SiC fibers were treated at different temperature under vacuum and Ar atmosphere to analyze the influence of fiber composition and atmosphere on the high temperature evolution of SiC fibers. The results reveal that SiC decomposition and graphene formation could occur in SiC fibers over 1600 °C under vacuum or 2000 °C under Ar atmosphere. The mechanical properties of both F1 and F2 fibers are remarkably degraded accompanied by the SiC decomposition. The formed graphene size is related to the SiC grain size before decomposition, while the increment of temperature will promote SiC grain growth and SiC decomposition simultaneously. Under Ar atmosphere, the Si sublimation rate is slow so that SiC grains can grow fully, therefore, the converted graphene crystallite size is much larger than that under vacuum. SiC decomposition rate is related to the excess carbon and pores in the fibers. The inhibition effect of carbon micro-coating around SiC grains formed by excess carbon and promotion effect of pores formed by SiCxOy decomposition co-exist in SiC fibers. This work reveals that effective inhibition of Si sublimation is of significance for the stability of SiC fibers under ultra-high temperature.

Influence of the gas atmosphere on the obtention of cobalt and iron based nanocomposites and core/shell nanoparticles by calcination in the presence of chitosan

In this work, CoFe2O4/CoFe2 nanoparticles with core/shell structure were synthesized by carbothermic reduction using chitosan beads impregnated with Fe3+ and Co2+ ions. The samples were synthesized at 400, 550, 650 and 750 ​°C, during intervals of 30, 90 and 120 ​min and under air, N2 and H2 gases. To apply the carbothermic method, chitosan was thermally decomposed in presence of N2 gas. The structural and magnetic properties were studied using X-ray powder diffraction, transmission electron microscopy, vibrating sample magnetometry and Mössbauer spectroscopy. The results showed that the Co–Fe impregnated chitosan beads thermally treated, firstly, in air at a given temperature and afterwards treated at 400 and 550 ​°C in H2 for 30 and 90 ​min led to the formation of CoFe2O4/CoFe2 nanoparticles, the samples treated at higher temperatures were single phase of CoFe2. However, the Co–Fe chitosan beads treated in N2 for 120 ​min at 550, 650 and 750 ​°C favored the formation of a core/shell (CoFe2O4/CoFe2) nanoparticles with CoFe2 concentration ranging from 75.5 to 35.0 ​Wt %, the amount of CoFe2 increased with the increase of temperature. The highest saturation magnetization of 227.7 emu/g was achieved for the sample treated at 550 ​°C under N2 atmosphere.

Arctic–Antarctic asymmetry of the ionospheric weather

The state of the ionosphere is investigated on a global scale, in the Arctic and Antarctic regions poleward of 60° magnetic latitudes. The Total Electron Content, TEC, enhancement (as represented by the global WU, polar WUN and WUS indices) and depletion (WL, WLN and WLS), and the respective ranges (WE, WEN and WES) are evaluated from global GIM-W index maps. GIM-W maps are derived from JPL GIM-TECs converted to geomagnetic coordinate frame for Solar Cycles 23–24. Using a superimposed epoch analysis, we examined 380 geo-storms caused by high speed solar wind stream, Vsw, with time t0 set at onset of the Dst storm and Dstmin ≤ −50 nT. Single-sign positive and negative storm effects are detected in both Arctic and Antarctic, when the polar WUN, WLN, WUS or WLS index is equal to zero for 10–20% of the pre-storm period, 5–25% for the main storm phase, and 7–25% during recovery. These asymmetric single-sign conditions violate the correlation between WUS (WUN) and WLN (WLS) data and global Dst, WU, WL and WE indices, demonstrated for the extreme storm on 15–17 July 2000 (Dst = −301 nT). The persistent single-sign conditions are observed in the polar segments for the both disturbed and quiet times from 1994 to 2021. The peak of the monthly single-sign conditions up to 50% of time occurs during the polar summer when the solar wind – polar ionosphere interaction at the open field lines facing the Sun is strengthened due to reduced magnetosphere shielding the solar wind. A long-term Arctic–Antarctic asymmetry is observed from 1994 to 2021, with larger values of daily polar indices WUN, WUS, WUN and WLS found for the winter hemisphere (the ‘winter anomaly’) while contribution of the multiple single-sign zeros yields the reduced monthly values at summer. The asymmetry is likely caused by the difference in the solar irradiance that is minimized at the dominant high-latitude winter night-time, compared to the sunlit summer conditions in the opposite hemisphere. Higher values of asymmetry index AIWU and AIWL shows dominant North Hemisphere variance over South Hemisphere during December solstice reversed towards the June solstice presumably related with dynamical influences of the lower atmosphere.

Исследование высокочастотного ионного двигателя с прямоточной конфигурацией разрядной камеры

The paper describes a zero-dimensional balance mathematical model of a radio-frequency ion thruster with a ramjet discharge chamber and considers the case when the propellant is fed into the ionization chamber but is able to outflow through the ion-extraction system as well as through the inlet channel of the atmosphere gases intake device. Nitrogen was considered as the propellant. The mathematical model is distinctive as it takes into account the propellant dissociation and the influence of atmosphere gases intake device. The paper also gives the results of the first experiments with a laboratory model of the thruster. The comparison between the calculated and experimental data made it possible to obtain the discrepancies of less than 15 percent, which indicates the applicability of the developed mathematical model for a qualitative analysis of the processes occurring in the thruster.

Noncatalytic hydropyrolysis of lignin in a high pressure micro-pyrolyzer

Lignin hydropyrolysis was investigated in a high-pressure micro-reactor with on-line analysis characterization of products. The influences of atmosphere, pressure, and temperature on product formation during lignin pyrolysis were quantitatively discussed. The presence of hydrogen, elevated pressure and temperature favored the production of condensable vapors and permanent gas while inhibited the formation of char. High-pressure hydrogen boosted the conversion of methoxy phenolics to non-methoxy phenolics, and facilitated the generation of hydrocarbon condensable vapors and hydrocarbon gases. Non-methoxy phenolics were major condensable vapor from lignin hydropyrolysis. Yield of non-methoxy phenolics reached 19.68C% at 3 MPa and 500 °C. The monocyclic and polycyclic aromatic hydrocarbons as well as condensable aliphatic hydrocarbons were observed from lignin hydropyrolysis. Methane was the most abundant gas product from lignin hydropyrolysis, yield of which was 10.27C% at 2 MPa and 600 °C. The formation mechanisms of typical products were proposed and verified with experiments using model compounds. The formation of non-methoxy phenolics, monocyclic aromatic hydrocarbons and aliphatic hydrocarbons is related to the substitution of methoxy (and its methyls) and phenolic hydroxyl groups on benzene rings by alkyls, alkenyls and hydrogen radicals, as well as the hydrogenation of π bonds.

Influence of the atmosphere and temperature on the properties of the oxygen-affine bonding system titanium-diamond during sintering

Grinding tools can be manufactured from metal, vitrified, and resin bond materials. In combination with superabrasives like diamond grains, metal-bonded tools are used in a wide range of applications. The main advantages of metal over vitrified and resin bonds are high grain retention forces and high thermal conductivity. This paper investigates the influence of the atmosphere and manufacturing parameters such as sintering temperature on the properties of titanium-bonded grinding layers. Titanium is an active bond material, which can increase the retention of diamond grains in metal-bonded grinding layers. This can lead to higher bond stress and, consequently, decreased wear of grinding tools in use when compared to other commonly used bond materials like bronze. The reason for this is the adhesive bond between titanium and diamond due to the formation of carbides in the interface, whereas bronze can only form a mechanical cohesion with diamond grains. However, when using oxygen-affine metals such as titanium, oxidizing effects could limit the strength of the bond due to insufficient adhesion between Ti-powder particles and the prevention of carbide formation. The purpose of this paper is to show the influence of the sintering atmosphere and temperature on the properties of titanium-bonded diamond grinding layers using the mechanical and thermal characterization of specimens. A higher vacuum (Δpatm = − 75 mbar) reduces the oxidation of titanium particles during sintering, which leads to higher critical bond stress (+ 38% @ Ts = 900 °C) and higher thermal conductivity (+ 3.4% @Ts = 1000 °C, Ta = 25 °C). X-ray diffraction measurements could show the formation of carbides in the cross-section of specimens, which also has a positive effect on the critical bond stress due to an adhesive bond between titanium and diamond.

Ag metal interconnect wires formed by pseudoplastic nanoparticles fluid imprinting lithography with microwave assistant sintering

Nanoimprint technology has the advantages of low cost, high precision, high fidelity and high yield. The metal nanoparticle fluid is non-Newtonian fluid, which is used as the imprint transfer medium to realize high fidelity of pattern because of its shear thinning effect. In order to functionalize the metal nanoparticles microstructure, the subsequent sintering step is required to form a metal interconnect wire. Metal interconnect wire with fewer grain boundaries and fewer holes have excellent mechanical and electronic properties. In this paper, the pseudoplastic metal nanoparticle fluid was formed by Ag nanoparticle and precursor solution, and then the thermal diffusion process was completed by microwave sintering after interconnects were embossed. The influence of microwave and thermal atmosphere on the microstructure and performance of Ag Interconnect wires was analyzed and discussed, and the Ag Interconnect wires performance was determined under the influence of time and temperature parameters. In our experiments, the interconnects after microwave sintering can achieve 39% of the conductivity of bulk silver. The microwave sintering module might be integrated as the heat treatment module of the metal micro/nano pattern directly imprint lithography.

A Sustainable Approach to the Preparation of MoO2 Quantum Dots and the Pseudocapacitive Performance before and after Calcination

The present preparation methods of molybdenum dioxide (MoO2) quantum dots (QDs) are often cumbersome and not environmentally friendly, and more importantly, the prepared MoO2 QDs are usually wrapped in surfactants, which are difficult to be removed and impact their intrinsic characterization and performance. Herein, we present a facile, scalable and sustainable approach to obtain clean and pure MoO2 QDs (1.5~3 nm), which consists of a hydrothermal reaction and a further calcination process in vacuum following freeze drying. Furthermore, the influence of calcination temperature, atmosphere and time is also studied. The calcination at 400 °C for 2 h in vacuum can efficiently remove the surfactants wrapping on the MoO2 QDs without obvious size change, whereas the calcination in nitrogen will lead to a slight increase in size, and the calcination in air could transform MoO2 QDs into MoO3 nanoplates. In addition, the pseudocapacitive performance of the as-prepared samples is tested and compared by electrochemical methods, and the specific capacitance of the clean MoO2 QDs is about 1.4 times larger than that of MoO2 QDs with surfactants at 5 mV s−1. This study also demonstrates a possible way to efficiently remove the organic substance wrapping on quantum dot materials.

The crucial role of molecular emissions on LIBS differentiation of organic compounds of interest in astrobiology under a Mars simulated atmosphere

In this work, the influence of Martian atmosphere on the recombination mechanisms in laser-induced plasmas of organic compounds of interest in astrobiology has been closely examined. The proposed LIBS methodology reveals new insights concerning the influence of the surrounding atmosphere on the molecular emission of organics. The presence of nitrogen, even in the short concentration found in the low-pressure Mars environment, influences the plasma chemistry and the formation pathways leading to molecular species. Characteristic atomic and molecular emitters (C, H, C2, CN, NH, OH and CH) were inspected in a set of selected organic compounds considered as meaningful biomarkers. For comparative purposes, LIBS analysis was performed in both low-pressure air and Martian atmospheres. Statistical analysis (linear discriminant analysis; DFA) suggested that satisfactory differentiation among materials was feasible under Martian conditions when molecular emissions are computed in the classification algorithm. Atomic lines (C, H) only contribute a mere ~62% to the discriminating analysis, whereas the percentage of successful discrimination was considerably increased (up to 99%) by the progressive introduction of signals associated to molecular bands into the DFA analysis, thus confirming the major contribution of molecular information to the final sorting performance and the feasibility of discriminating closely related organic compounds by LIBS in the Martian atmosphere.
