Remote-sensing monitoring of Neptune has revealed temperature variations in the atmosphere of the planet [1,2,3,4] since the flyby of Voyager 2 [5]. These variations are not uniform in latitude or pressure level, with the Southern polar region and the stratospheric pressure levels showing higher levels of activity. In this work we present the analysis of ALMA observations of Neptune at the CO(3-2) line at 345.8GHz. These measurements were recorded in 2016 with a spatial resolution of about 0.37” on Neptune’s 2.24” disk. We find that this spectral range is sensitive to Neptune’s upper troposphere and lower stratosphere, probing between about 1 and 10-3 bar.We developed an MCMC retrieval methodology coupled to a pre-existing radiative transfer code [6] to derive Neptune’s temperature fields and constrain the atmospheric abundance of CO. We explored the correlation between both parameters by carrying out simultaneous retrievals to the temperature and CO abundance, both on disk-averaged and spatially-resolved data. We then explored the latitudinal variations of temperature and derived temperature maps of the planet. We compare these results with previous works in the literature, and discuss the latitudinal variability measured with ALMA. [1] Orton et al. 2007, A&A 473, L5[2] Lellouch et al. 2010, A&A 518, L152[3] Fletcher et al. 2014, Icarus 231, 146–167[4] Roman et al. 2022, Planet.

Abstract. This paper describes the addition of a stratospheric prognostic aerosol (SPA) capability – developed with the goal of accurately simulating sulfate aerosol formation and evolution in the stratosphere – in the Department of Energy (DOE) Energy Exascale Earth System Model, version 2 (E3SMv2). The implementation includes changes to the four-mode Modal Aerosol Module microphysics in the stratosphere to allow for larger particle growth and more accurate stratospheric aerosol lifetime following the Pinatubo eruption. E3SMv2-SPA reasonably reproduces stratospheric aerosol lifetime, burden, aerosol optical depth, and top-of-atmosphere flux when compared to remote sensing observations. E3SMv2-SPA also has close agreement with the interactive chemistry–climate model CESM2-WACCM (Community Earth System Model version 2–Whole Atmosphere Community Climate Model) – which has a more complete chemical treatment – and the observationally constrained, prescribed volcanic aerosol treatment in E3SMv2. Global stratospheric aerosol size distributions identify the nucleation and growth of sulfate aerosol from volcanically injected SO2 from both major and minor volcanic eruptions from 1991 to 1993. The modeled aerosol effective radius is consistently lower than satellite and in situ measurements (max differences of ∼ 30 %). Comparisons with in situ size distribution samples indicate that this simulated underestimation in both E3SMv2-SPA and CESM2-WACCM is due to overly small accumulation and coarse-mode aerosols 6–18 months post-eruption, with E3SMv2-SPA simulating ∼ 50 % of the coarse-mode geometric mean diameters of observations 11 months post-eruption. Effective radii from the models and observations are used to calculate offline scattering and absorption efficiencies to explore the implications of smaller simulated aerosol size for the Pinatubo climate impacts. Scattering efficiencies at wavelengths of peak solar irradiance (∼ 0.5 µm) are 10 %–80 % higher for daily samples in models relative to observations through 1993, suggesting higher diffuse radiation at the surface and a larger cooling effect in the models due to the smaller simulated aerosol; absorption efficiencies at the peak wavelengths of outgoing terrestrial radiation (∼ 10 µm) are 15 %–40 % lower for daily samples in models relative to observations, suggesting an underestimation in stratospheric heating in the models due to the smaller simulated aerosol. These potential biases are based on aerosol size alone and do not take into account differences in the aerosol number. The overall agreement of E3SMv2-SPA with observations and its similar performance to the well-validated CESM2-WACCM makes E3SMv2-SPA a viable alternative to simulating climate impacts from stratospheric sulfate aerosols.
População e fome: indicadores de insegurança alimentar e os objetivos de desenvolvimento sustentável da ONU
Authors: Freitas Carla
Published: July 2024

In this work, we aim to address the issue of population and hunger, indicators of food insecurity in Brazil and in the world and how the Sustainable Development Goals of the United Nations (UN) can be a way forward to help eradicate hunger. To build this article, we used qualitative and quantitative approaches. At first, we carried out a bibliographical study, a theoretical-methodological survey and also collected and analyzed secondary data from reports and websites such as the Brazilian Institute of Geography and Statistics (IBGE), UN and United Nations Food and Agriculture Organization (FAO). We conclude that some population variations have changed in recent decades: fertility has decreased and population has increased; and that, with this increase in population, the supply of food also increased. However, there are still people in many parts of the world who suffer from serious food insecurity, that is, hunger itself; and in Brazil the data show that this index continues to grow.

The work is devoted to the study of the features of mass transfer, structure and properties of electrospark coatings on substrates made of the chromium alloy grade VKh1-17A using SHS-electrode ceramics of the compositions ZrSi2-MoSi2-ZrB2 and HfSi2-MoSi2-HfB2. The coatings were studied using X-ray diffraction, scanning electron microscopy, energy-dispersive analysis, and tribological tests using the “pin-on-disk”; nanoindentation was also carried out. The kinetics of the mass transfer and heat resistance of coatings were determined by the gravimetric method. In accordance with the Palatnik criterion, the formation of coatings occured in the form of an alloy of an anode (electrode) and a cathode (substrate) materials, which ensures high adhesion of the surface layer. The maximum weight gain on the cathode was observed after the first minute of treatment, and subsequently a decrease in the mass of the cathode was noted. As a result of electrospark deposition, coatings with 100% continuity and a thickness of 10–20 µm were deposited on the surface of the chrome alloy VKh1-17A. Zirconium-containing coatings are characterized by a hardness of 18.2 GPa and an elastic modulus of 274 GPa, and coatings obtained using the HfSi2-MoSi2-HfB2 electrode were characterized by a hardness of 16.9 GPa and an elastic modulus of 332 GPa. The use of SHS-electrodes made it possible to increase the hardness of the surface layer of the chromium alloy by 4 times, wear resistance by 1.5 times, and oxidation resistance by 1.6 times at t 1000 °C for 30 hours of testing.

Published: July 2024

The temperature and frequency dependences of the dielectric constant and electrical conductivity of FeGa0,4In1,6Se4 crystals on alternating current have been studied. In the FeGa0,4In1,6Se4 crystal, normal dispersion occurs in the frequency range 2·102104 Hz, and the lifetime distribution of defects obeys the law n(τ) ~ τ−1.75. With increasing temperature, the reason for an increase in the value of the real part of the dielectric constant is an increase in the concentration of defects. The experimentally observed monotonic decrease in the imaginary part of the dielectric constant depending on frequency indicates the presence of relaxation dispersion in the FeGa0.4In1.6Se4 crystal. It has been established that in the temperature range 294,5 ÷ 343 K at frequencies 2∙102 ÷ 106 Hz for electrical conductivity the law σ ~ f S (0.1 ≤ S ≤ 1.0) is satisfied. It was shown that the conductivity in those crystals is characterized by a band-hopping mechanism. Activation energies were determined from the dependencies.

Contribution of Gas Flare on the Rainwater of the Braced States in the Niger Delta
Authors: P. O. Boyitie , S. I. Efe , A. O. Atubi
Published: July 2024

Gas flaring contaminates rainwater, which harms the ecology. Exposure to flared gas turns rainwater acidic. The study examined the rainwater quality in gas flare areas of the BRACED states of the Niger Delta. The study employed an ex-post facto research design to assess the quality of rainwater in the industrial regions of the BRACED Niger Delta states. Rainwater samples were collected from twelve (12) locations in the BRACED Niger Delta states near refineries and gas flaring sites. The results show that the rainwater near GHG-impacted areas of the BRACED states has an average pH of 6.7, which is below the guidelines set by the World Health Organisation (WHO). A pH lower than the required WHO standards suggests acidic rainwater. The temperature is 27.4 °C, the conductivity is 37.1µS/cm, and the phosphate concentration exceeds WHO guidelines. Nitrate and sulphate levels are below WHO guidelines. P<0.05 indicates substantial changes in pH value and temperature amount in rainwater quality. Acidic rains, high temperatures, and high phosphate concentrations characterise the BRACED States, raising concerns about the suitability of rainwater for drinking. The study underscores the need for a comprehensive approach to controlling gas flaring, which includes taxation, anti-acidic coating measures, and infrastructure upgrades.

В статье представлены результаты исследования по разработке режимов приготовления концентрированной молочнокислой закваски с использованием цельнозерновой муки в качестве питательной смеси и предназначенной для применения в технологии мультизерновых хлебобулочных изделий. Для определения режимов приготовления закваски исследовали изменения показателей титруемой и активной кислотности в процессе ее брожения в разводочном цикле. Измерение значений титруемой и активной кислотности проводили в течение 24 ч для первой фазы, 18 ч для второй фазы, 12 ч для третьей фазы. Начальное значение активной кислотности закваски на первой фазе разводочного цикла составляло 6,25, на второй фазе – 4,96, на третьей фазе – 4,83. Полученная зависимость активной кислотности от продолжительности брожения КМКЗ, приготовленной с использованием цельнозерновой муки, описывалась с помощью дифференциального уравнения, где величина pH экспоненциально уменьшалась от максимального начального значения к неизменному конечному значению. Таким образом, были установлены оптимальные режимы приготовления закваски: постоянное значение pH на первой фазе составило 3,59 через 12 ч, на второй и третьей фазах – 3,58 через 9 ч. На основании проведенных исследований определены режимы приготовления КМКЗ с использованием муки цельнозерновой полбяной, обеспечивающие оптимальные технологические свойства закваски, что будет способствовать формированию повышенных показателей качества и пищевой ценности мультизерновых хлебобулочных изделий.

The article presents the results of a study of preparation modes for maintaining concentrated lactic sourdough prepared using whole grain flour and intended for use in the technology of multigrain bakery products. To determine the modes of sourdough preparation, we studied changes in titratable and active acidity during its fermentation in the breeding cycle. Measurement of titratable and active acidity values was carried out within 24 hours for the first phase, 18 hours for the second phase, 12 hours for the third phase. The initial value of the active acidity of the starter in the first phase of the breeding cycle was 6.25, in the second phase – 4.96, in the third phase – 4.83. The resulting dependence of active acidity on the duration of fermentation of KMKZ prepared using whole grain flour was described using a differential equation, where the pH value decreased exponentially from the maximum initial value to a constant final value, thus, the optimal modes of fermentation were established: a constant pH value for in the first phase it was 3.59 after 12 hours, in the second and third phases – 3.58 after 9 hours. Based on the conducted research, the preparation modes for KMKZ using whole grain spelled flour were determined, providing optimal technological properties of the sourdough, which will contribute to the formation of increased quality indicators and nutritional value of multigrain bakery products.
