This study investigated the suitability of drinking water in Orlu, Nigeria, facing challenges due to limited surface water availability and environmental deterioration. To solve the problem of the availability of portable water, electrical resistivity surveys using a Schlumberger array were conducted to identify potential groundwater resources. Twelve locations were assessed, revealing resistivity values indicative of potential aquifers. Following the geophysical survey, the physicochemical properties of water samples collected from various locations were analyzed. Parameters including pH, dissolved oxygen (DO), total dissolved solids (TDS), and minerals were evaluated against WHO and Nigerian drinking water standards. The analysis indicated generally good water quality across the sampling sites. pH levels were within the recommended range, and DO concentrations met the minimum requirements. Similarly, TDS and BOD values suggested low levels of organic matter and dissolved solids. Mineral content also remained below WHO-permissible limits. A Water Quality Index further confirmed that the water quality within the study area can be graded from good to excellent in quality. These findings suggest that the groundwater resources identified in the study hold promise for providing safe drinking water in Orlu and its environs.

Value of computed tomography pulmonary angiography measurements in predicting 30-day mortality among patients with acute pulmonary embolism
Authors: Akcalar Zorlu Seray 
Published: May 2024

PurposeLate diagnosis is associated with high mortality rates in acute pulmonary embolism (PE), so early diagnosis and risk assessment are crucial. We aim to evaluate computed tomography pulmonary angiography measurements to identify relationships with 30-day mortality in patients with pulmonary embolism. This study investigated the utility of computed tomography pulmonary angiography (CTPA) measures in determining 30-day PE-related mortality and identified various echocardiographic, demographic, and clinical variables that were independently associated with short-term mortality in patients with acute PE.Material and methodsThis retrospective study examined data from July 2018 to April 2023. A total of 118 patients were included in the study. Clinical and demographic characteristics, laboratory findings, echocardiographic data, and CTPA images were retrieved from the electronic database and patient charts.ResultsThe rate of 30-day mortality was 14.41%. Deceased patients were significantly older than survivors (73.53 ± 14.17 vs. 60.23 ± 17.49 years; <i>p</i> = 0.004), but the sex distribution was similar. In multivariable logistic regression, having received radiotherapy for malignancy, high pulmonary artery obstruction index % (> 46.2), high left pulmonary artery diameter (> 23.9 mm), and high coronary artery calcification score (> 5.5) were independently associated with mortality.ConclusionsThese results reveal specific parameters that can assist acute PE management by enabling the identification of critical events. Despite promising results in predicting short-term mortality in acute PE, further prospective cohort studies are needed to confirm the results of the present study.

Published: May 2024

Abstract. There are growing concerns about the climate impacts of absorbing organic carbon (also known as brown carbon, BrC) in the environment, yet its chemical composition and association with the light absorption capabilities remain poorly understood. This study characterized water-soluble and water-insoluble organic carbon (WSOC and WIOC) from residential solid fuel combustion at the molecular level and evaluated their quantitative relationship with mass absorption efficiency (MAE). The MAE values at λ = 365 nm from biomass burning were significantly higher than those from coal combustion (p < 0.05). Thousands of peaks were identified in the m/z range of 150–800, with the most intense ion peaks occurring between m/z 200–500 for WSOC and m/z 600–800 for WIOC, respectively. The CHO group predominated in the WSOC extract from biomass burning emissions, while sulfur-containing compounds (SOCs) including CHOS and CHONS were more intense in the WIOC extract, particularly from coal emissions. Emissions of the CHON group were positively correlated with the fuel nitrogen content (r = 0.936; p < 0.05), explaining their higher abundance in coal emissions compared to biomass. The SOC emissions were more predominant during flaming phases, as indicated by a positive correlation with modified combustion efficiency (MCE) (r = 0.750; p < 0.05). The unique formulas of coal combustion aerosols were in the lower H/C and O/C regions, with higher unsaturated compounds in the van Krevelen (VK) diagram. In the WIOC extract, coal combustion emissions contained significantly higher fractions of condensed aromatics (32 %–59 %) compared to only 4.3 %–9.7 % in biomass burning emissions. In contrast, the CHOS group in biomass burning emissions was characterized by larger condensed aromatic compound fractions than those in coal combustion. Moreover, the CHOS aromatic compound fractions were positively correlated with MAE values in both WSOC (r = 0.714; p < 0.05) and WIOC extracts (r = 0.929; p < 0.001), suggesting that these compounds significantly contributed to MAE variabilities across different fuels.

Abstract. Solar Orbiter is equipped with electrical antennas performing fast measurements of the surrounding electric field. The antennas register high-velocity dust impacts through the electrical signatures of impact ionization. Although the basic principle of the detection has been known for decades, the understanding of the underlying process is not complete, due to the unique mechanical and electrical design of each spacecraft and the variability of the process. We present a study of electrical signatures of dust impacts on Solar Orbiter's body, as measured with the Radio and Plasma Waves electrical suite. A large proportion of the signatures present double-peak electrical waveforms in addition to the fast pre-spike due to electron motion, which are systematically observed for the first time. We believe this is due to Solar Orbiter's unique antenna design and a high temporal resolution of the measurements. The double peaks are explained as being due to two distinct processes. Qualitative and quantitative features of both peaks are described. The process for producing the primary peak has been studied extensively before, and the process for producing the secondary peak has been proposed before (Pantellini et al., 2012a) for Solar Terrestrial Relations Observatory (STEREO), although the corresponding delay of 100–300 µs between the primary and the secondary peak has not been observed until now. Based on this study, we conclude that the primary peak's amplitude is the better measure of the impact-produced charge, for which we find a typical value of around 8 pC. Therefore, the primary peak should be used to derive the impact-generated charge rather than the maximum. The observed asymmetry between the primary peaks measured with individual antennas is quantitatively explained as electrostatic induction. A relationship between the amplitude of the primary and the secondary peak is found to be non-linear, and the relation is partially explained with a model for electrical interaction through the antennas' photoelectron sheath.
Implementation and evaluation of diabatic advection in the Lagrangian transport model MPTRAC 2.6

Published: May 2024

Abstract. Diabatic transport schemes with hybrid zeta coordinates, which follow isentropes in the stratosphere, are known to greatly improve Lagrangian transport calculations compared to the kinematic approach. However, some Lagrangian transport calculations with a diabatic approach, such as the Chemical Lagrangian Transport Model of the Stratosphere (CLaMS), are not well prepared to run on modern high-performance computing (HPC) architectures. Here, we implemented and evaluated a new diabatic transport scheme in the Massive-Parallel Trajectory Calculations (MPTRAC) model. While MPTRAC can be used either with shared-memory multiprocessing on CPUs or with GPUs to offload computationally intensive calculations, making it flexible for many HPC applications, it has been limited to kinematic trajectories in pressure coordinates. The extended modelling approach now enables the use of either kinematic or diabatic vertical velocities and the coupling of different MPTRAC modules based on pressure or hybrid zeta coordinates. This study focus on the accuracy of the implementation in comparison to the CLaMS model. The evaluation of the new transport scheme in MPTRAC shows that, after 90 d of forward calculations, distributions of air parcels in the upper troposphere and lower stratosphere (UTLS) are almost identical for MPTRAC and CLaMS. No significant bias between the two Lagrangian models was found. Furthermore, after 1 d, internal uncertainties (e.g. due to interpolation or the numerical integration method) in the Lagrangian transport calculations are at least 1 order of magnitude smaller than external uncertainties (e.g. from reanalysis selection or downsampling of ERA5). Differences between trajectories using either CLaMS or MPTRAC are on the order of the combined internal uncertainties within MPTRAC. Since the largest systematic differences are caused by the reanalysis and the vertical velocity (diabatic vs. kinematic), the results support the development efforts for trajectory codes that can access the full resolution of ERA5 in combination with diabatic vertical velocities. This work is part of a larger effort to adapt Lagrangian transport in state-of-the-art models such as CLaMS and MPTRAC to current and future HPC architectures and exascale applications.
Soft Acoustic Metamaterials: from 3D locally resonant metafluids to soft porous gradient index metasurfaces
Authors: Brunet Thomas 
Published: May 2024

Soft acoustic metamaterials are classes of functional materials for acoustics achieved by means of soft matter techniques such as microfluidics, chemical formulation or self-assembly [1]. In this talk, I will review our achievements in that field that allowed us to fabricate the first 3D acoustic metamaterial with a negative index [2]. To do that, we took benefit from the strong low-frequency Mie-type resonances of “ultra-slow” micro-beads randomly dispersed in a water-based gel. The soft porous silicone rubber material used to make these soft porous particles, not only exhibits ultra-low sound speeds ( 40m/s), but also shows a strong dependence of its sound speed on the porosity [3], providing thus a material with an acoustic index varying over a wide range of values. By assembling thin stripes made of these soft porous silicone rubbers with different porosities, we have recently proposed to fabricate soft gradient-index metasurfaces, alternatively to our 3D locally resonant metafluids, for wavefront shaping. The ability of these flat and ultra-thin acoustic lenses will be demonstrated through various underwater ultrasound experiments such as beam steering, ultrasound focusing and vortex beam generation [4]. Finally, I will report on 3D underwater ultrasound focusing experiments performed with a quasi-flat high-index acoustic lens [5] whose focal length can be tuned by hardening or softening the material thanks to UV light [6].

This research aims to test and analyze the influence of foreign indices in the form of DJIA and macroeconomic variables in the form of inflation, BI-Rate, exchange rate, and world gold prices on ISSI over the period from 2012 to 2021. This research uses quantitative methods with secondary data in the form of time-series. The analytical techniques used are the VAR and VECM. The research used data processing in the form of e-views 12 software. The results of this study show that in the long-term DJIA, BI-Rate, and exchange rate have a significant positive effect on the ISSI. Meanwhile, inflation variables and gold prices in the long term have a significant negative effect on ISSI. In the short-term, only inflation variable has a significant negative effect on ISSI. Meanwhile, other variables in the form of DJIA, BI-Rate, exchange rate, and world gold price did not have a significant effect on the ISSI. The results of this research can be used as additional information and considerations for companies in carrying out policies related to investment and can be used in anticipating the effects of macroeconomic changes for the stability of company value. In such a way, companies are able to consider them when choosing which investments and businesses need to be aware of the macroeconomic factors in a nation that can affect stock performance.

A aquicultura mundial está em crescimento, por isso, aumentaram significativamente as pesquisas relacionadas aos alimentos alternativos e aditivos alimentares que melhorem a utilização dos nutrientes ingeridos na dieta, permitindo que os animais consigam apresentar um melhor desempenho zootécnico, além de auxiliar no sistema imune, com maior taxa de sobrevivência. A utilização dos ácidos orgânicos aumenta a atividade antimicrobiana, reduz o pH do intestino e estômago, e consequentemente tem efeitos positivos no desempenho zootécnico e utilização dos nutrientes pelos animais. O resultado da ação dos ácidos orgânicos é variável, de acordo com a espécie-específica e a idade dos animais. Portanto, mesmo que na literatura hajam resultados de estudos realizados com uma determinada espécie, isso não evidencia que tal inclusão é eficaz em outra espécie. O uso de probióticos e prebióticos evita a perda da diversidade de bactérias no intestino e seu mecanismo de ação impede que bactérias patogênicas colonizem o intestino do peixe. Além disso, fazem o equilíbrio da microbiota intestinal, fazem a produção de substâncias antimicrobianas e aumentam a atividade das enzimas, melhorando a digestão e absorção dos nutrientes. O prebiótico possui eficácia para estimular a crescimento de bactérias benéficas, reduzindo o crescimento de microrganismos patogênicos como Salmonellas e Escherichia coli, favorecendo o equilíbrio da microbiota intestinal, melhorando o desempenho produtivo e a saúde do animal. A modulação da microbiota contribui positivamente na imunomodulação do sistema de defesa dos animais. Os probióticos possuem capacidade de promover maior crescimento e ganho em peso dos animais, além de aumentar a resistência a bactérias patogênicas como a Streptococcus agalactiae. O objetivo da presente revisão bibliográfica foi elencar diversos trabalhos sobre aditivos prebióticos, probióticos e ácidos orgânicos na dieta de peixes e destacar seu uso e importância para as espécies que receberam em sua alimentação. É possível verificar a grande complexidade e desafios na utilização dos aditivos frentes às diferentes situações de criação e resultados diversos, contudo, é verificado importância principalmente na ação sobre o desempenho zootécnico e na saúde dos peixes.
