LSTM Network for the Oxygen Concentration Modeling of a Wastewater Treatment Plant
Authors: Toffanin Chiara , Palma Federico , Iacono Francesca , Magni Lalo
Published: May 2023

Activated sludge process is a well known method to treat municipal and industrial waste water. In this complex process, the oxygen concentration in the reactors plays a critical role in the plant efficiency. This paper proposes the use of a Long Short-Term Memory (LSTM) network to identify an input-output model suitable for the design of an oxygen concentration controller. The model is identified from easy-accessible measures collected from a real plant. This dataset covers almost a month. The performances achieved with the proposed LSTM model are compared with the ones obtained with a standard AutoRegressive model with eXogenous input (ARX). Both models catch the oscillation and the overall behaviour (ARX ρ=0.833 , LSTM ρ=0.921), but, while the ARX model fails in reaching the correct amplitude (FIT=41.20%), the LSTM presents satisfactory performance (FIT=60.56%).

Published: May 2023

The Süttő 21 site is a fissure fill of the freshwater limestone of the Gazda quarry in Süttő. The material was collected between 2017 and 2019, the results are summarised in this article, with a special focus on the small vertebrate fauna of the site and its stratigraphic and paleoecological significance.
The fissure fill can be placed around the early/middle Pleistocene boundary (ca. 1.1 and 0.77 Ma). The paleoecological analysis of the herpeto- and mammal fauna of the sequence indicates the proximity of a permanent water body. The lower part of the sequence is dominated by open habitat indicator taxa indicating a cool, dry climate. Towards the upper part of the sequence, the climate remained cool but became wetter, and the vegetation gradually changed to forest-steppe/open forest.
The fauna of the Süttő 21 site can be compared with the material of sites, which are of similar age, thus revealing taxonomic and paleoecological differences between different areas of the country. While a warm, dry climate and open vegetation can be reconstructed in the Villány Hills around the early/middle Pleistocene boundary, the northern Hungarian areas had a cooler, wetter climate, and slightly more closed (grove, forest-steppe) vegetation during this period.
Effectiveness of Lifestyle Nutrition and Physical Activity Interventions for Childhood Obesity and Associated Comorbidities Among Children From Minority Ethnic Groups: Systematic Review and Meta-analysis
Authors: Obita George , Alkhatib Ahmad
Published: May 2023

Lifestyle physical activity (PA) and nutrition are known to be effective interventions in preventing and managing obesity related comorbidities is adult populations, but less so in children and adolescents. We examined the effectiveness of lifestyle interventions in children from minority ethnic populations in western high-income countries.

Our systematic review included 53 studies involving 26045 children from minority ethnic populations within western countries, who followed lifestyle intervention programs lasting between 8 weeks and 5 years with an aim to prevent and/or manage childhood obesity and associated comorbidities, including adiposity and cardiometabolic risks. Studies were heterogenous in terms of lifestyle intervention components (nutrition, PA, behavioural counselling) and settings (community vs. schools and after schools).

Our meta-analysis included 31 eligible studies and showed no significant effects of lifestyle interventions when they focused on body weight and body mass index (BMI) outcomes [pooled BMI mean change = -0.09 (95% CI -0.19, 0.01), p=0.09]. This was irrespective of the intervention program duration (< 6 months vs. ≥ 6 months), type (PA vs nutrition/combined intervention) and weight status (overweight or obese vs no normal weight), all showed no significant effects in the sensitivity analysis. Nonetheless, 19 of the 53 studies reported reduction in BMI, BMI z scores and body fat percentage. However, majority of lifestyle interventions adopting a quasi-design with a combined primary and secondary obesity measures (11 out of 15 studies), were effective in reducing obesity comorbidities of cardiometabolic risks including metabolic syndrome, insulin sensitivity, and blood pressure in children with overweight and obesity.

Preventing childhood obesity and associated comorbidities in children from high-risk ethnic minority groups is best achieved using a combined PA and nutrition intervention approach, which jointly target preventing obesity and cardiometabolic disease primary and secondary outcomes, especially measures of diabetes, hypertension, and cardiovascular disease.

Published: May 2023

The rapid development of quantum computing devices promises powerful machines with capabilities that solve a wide range of problems that traditional computers cannot. Therefore, quantum computers generate new threats at unprecedented speed and scale and specifically pose an enormous threat to encryption. Lattice-based cryptography is considered to be the rival to a quantum computer attack and the future of post-quantum cryptography. So, cryptographic protocols based on lattices have a variety of benefits, like security, efficiency, lower energy consumption, and speed. In this work, we study the most well-known lattice-based cryptosystems while a systematic evaluation and comparison is presented also, and focuses on their strengths and weaknesses.
In Silico Identification of Apple Genome-Encoded MicroRNA Target Binding Sites Potentially Targeting the ACLSV
Authors: Ashraf Muhammad Aleem , Murtaza Nimra , Brown Judith K , Yu Naitong
Published: May 2023

Apple chlorotic leaf spot virus (ACLSV) is a widespread, deleterious and the most damaging pathogen of fruit tree plants including domesticated apple (Malus domestica) ―a great threat to apple production worldwide. The positive-sense single-stranded RNA genome of ACLSV (7.5 Kbp) encodes three proteins: RNA polymerase (Rep), movement protein (MP) and coat protein (CP). RNA interference (RNAi)-mediated antiviral innate immunity is a key sequence-specific biological phenomenon in eukaryotes to control plant viruses. The aim of this study was to analyze apple (M.domestica) locus-derived microRNAs (mdm-miRNAs) with predicted potential for targeting the ACLSV +ssRNA-encoded mRNAs, using ‘four algorithms’ approach. The ultimate goal in this research is to mobilize the in silico endogenous predicted mdm-miRNAs to trigger RNAi catalytic pathway experimentally and generate apple tree varieties for evaluating potential antiviral resistance monitoring capability and capacity for ACLSV. Experimentally validated mature apple (M.domestica, 2n = 2X = 34) mdm-miRNAs (n = 322) were acquired from miRBase database and tested for alignment with the ACLSV genome. Of the 322 targeting mature locus-derived mdm-miRNAs investigated, nine apple mdm-miRNA homologs (mdm-miR395k, mdm-miR5225c and mdm-miR7121 (a, b, c, d, e, f, g, h) were predicted by all ‘four algorithms’. Only fifty eight mdm-miRNAs were predicted consensus binding sites by union of consensus between two algorithms. The miRanda, RNA22, TAPIR algorithms predicted binding of mdm-miR395k at unique nucleotide position 4691, as the most effectively interacting mdm-miRNAs in targeting the ORF1 sequence. In order to validate target prediction accuracy, whether the apple mdm-miRNAs might bind predicted ACLSV mRNA target(s), we created an integrated Circos plot. Genome-wide in-silico-predicted miRNA-mediated target gene regulatory network validated interactions that warrant in vivo analysis. The current work provides valuable evidence and biological material for generating ACLSV-resistant apple varieties.

Published: May 2023

Indirect calorimetry (IC) is a widely used method to study animal energy metabolism by measuring gas exchange. The accuracy of IC depends on detecting variations in signals reflecting the metabolic response, which can be challenging due to measurement noise and external factors. In this study, we propose a methodology to validate IC systems, including an easy-to-use spreadsheet for data computing, to verify accuracy and detect whole-system leaks. We conducted a re-covery test using a simulation of CO2 dynamics in MS Excel and injecting a known CO2 concentration into four respirometry chambers. The clearance rate of CO2 was observed and compared to the expected clearance rate from the simulation. The results from the recovery test in our system show that the proposed methodology is accurate and precise. The proposed methodology and recovery test can be used to standardize the validation of IC systems, providing accurate measurements of animal energy metabolism in different environmental conditions and energy utilization from feeds.

Published: May 2023

The effective detection of viruses in aircraft wastewater is crucial to establish surveillance programs for monitoring virus spread via aircraft passengers. This study aimed to compare the performance of two virus concentration workflows, adsorption-extraction (AE) and Nanotrap® Microbiome A Particles (NMAP), in detecting the prevalence and concentrations of 15 endogenous viruses in aircraft lavatory wastewater samples. The viruses tested include two indicator viruses, four enteric viruses, and nine respiratory viruses. The results showed that cross-assembly phage (crAssphage), human polyomavirus (HPyV), rhinovirus A (RhV A), and rhinovirus B (RhV B) were detected in all wastewater samples using both workflows. However, enterovirus (EV), human norovirus (HNoV GII), human adenovirus (HAdV), bocavirus (BoV), parechovirus (PeV), epstein-barr virus (EBV), influenza A virus (IAV), and respiratory syncytial virus B (RsV B) were infrequently detected by both workflows, and hepatitis A virus (HAV), influenza B virus (IBV), and respiratory syncytial virus B (RsV A) were not detected in any samples. The NMAP workflow had greater detection rates of EV, PeV, and RsV B than the AE workflow, while the AE workflow had greater detection rates of HAdV, BoV, and EBV than the NMAP workflow. The concentration of each virus was also analyzed, and the results showed that CrAssphage had the highest mean concentration (6.76 log10 GC/12.5 mL) followed by HPyV (5.46 log10 GC/12.5 mL using the AE workflow, while the mean concentrations of enteric and respiratory viruses ranged from 2.48 to 3.63 log10 GC/12.5 mL. Using the NMAP workflow, the mean concentration of crAssphage was 5.18 log10 GC/12.5 mL and the mean concentration of HPyV was 4.20 log10 GC/12.5 mL, while mean concentrations of enteric and respiratory viruses ranged from 2.55 to 3.74 log10 GC/12.5 mL. The mean concentrations of CrAssphage, HPyV, RhV A, and RhV B between the two workflows were statistically significant (p < 0.05). In summary, the present study provides valuable insights into the performance of virus concentration workflows in detecting and quantifying different viruses in aircraft lavatory wastewater samples. The findings can aid in the selection of an appropriate concentration workflow for virus surveillance studies and contribute to the development of efficient and reliable virus detection methods.
The Expansion of Data Science: Datasets Standardization
Authors: Pessanha Santos Nuno
Published: May 2023

With the recent advances in science and technology, more processing capability and data have become available, allowing a more straightforward implementation of data analysis techniques. Fortunately, the available online data storage capacity follows this trend, and vast amounts of data can be stored online freely or at accessible costs. As happens with every evolution (or revolution) in any science field, organizing and sharing this data is essential to contribute to new studies or validate the obtained results quickly. To facilitate this, we must guarantee interoperability between the existing datasets and the developed software, whether commercial or open source. This article explores this issue, analyzing the current initiatives to establish data standards and comparing some of the existing dataset online storage platforms. Through a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis, it is possible to understand better the strategy that should be taken to improve the efficiency in this field, which directly depends on the data characteristics.

Published: May 2023

The objective of this study was to compare the effect of different botanical powders and synthetic chemical in controlling Sitophilus zeamais in stored maize. A laboratory experiment was done to assess three botanicals, Zingiber officinale, Moringa oleifera, Xylopia aethiopica, in controlling the S. zeamais. The results of this study demonstrated the active potentials of these plant products as plant-derived insecticides against maize weevil. The synthetic chemical used showed both higher weevil mortality and higher grain loss than the botanicals (P< 0.05). The Botanicals also showed significance difference in the mortality rate (P < 0.05) as Z. officinale recorded the highest mortality rate (5.66%) while X. aethiopica recorded the lowest mortality rate (3.66%). The control attained the highest grain damage (7.33%) while amongst the botanicals, the highest was found in Z. officinale (7.33%) and lowest was on M. oliefera (5.33%). The exit holes made by the weevils at the end of the experiment were highest (2.66) in M. oliefera whereas lowest was recorded on X. aethiopica (1.00). Z. officinale, X. aethiopica and M. oleifera were efficacious against S. zeamais instead of synthetic chemical insecticides that have environmental health hazards and they can be used in integrated pest management by farmers and foods merchants. Therefore, since these botanicals have no any adverse effects on the seeds and safe to the environment, they are recommended for future usage in storage grains to control of S. zeamais.
Genetic Targeting of the dTORC1 Inhibitor, dSAMTOR, during Drosophila Aging: A Tissue-specific Pathology

Published: May 2023

mTORC1 regulates mammalian cell metabolism and growth, in response to diverse environmental stimuli. Nutrient signals control the localization of mTORC1 onto lysosome-surface scaffolds that are critically implicated in its amino acid-dependent activation. Arginine, Leucine and S-Adenosyl-Methionine (SAM) can serve as major mTORC1-signaling activators, with SAM binding to SAMTOR (SAM + TOR), a fundamental SAM sensor, abolishing protein’s (SAMTOR’s) inhibitory action(s) against mTORC1, thereby releasing its (mTORC1) kinase activity. Given the lack of knowledge regarding the role of SAMTOR in invertebrates, we have, in silico, identified the Drosophila SAMTOR homologue (dSAMTOR) and have, herein, genetically targeted it, through utilization of the GAL4/UAS transgenic tool. Survival profiles and negative geotaxis patterns were examined both in control and dSAMTOR-downregulated adult flies, during aging. One of the two gene-targeted schemes resulted in lethal phenotypes, whereas the other one caused rather moderate pathologies in most tissues. Screening of head-specific kinase activities, via PamGene technology application, unveiled the significant upregulation of several kinases, including the dTORC1 characteristic substrate, dp70S6K, in dSAMTOR-downregulated flies, thus strongly supporting the inhibitory dSAMTOR function(s) upon dTORC1/dp70S6K signaling axis in Drosophila-brain settings. Importantly, genetic targeting of the Drosophila BHMT -bioinformatics- counterpart (dBHMT), an enzyme that catabolizes Betaine to produce Methionine (the SAM precursor), led to severe compromises in fly longevities, with glia-, motor neuron- and muscle-specific dBHMT downregulations exhibiting the strongest effects. Abnormalities in wing-vein architectures were also detected in dBHMT-targeted flies, thereby justifying their notably reduced negative geotaxis capacities, herein, observed, mainly in the brain-(mid)gut axis. In vivo adult-fly exposure to clinically relevant doses of Methionine revealed the mechanistic synergism of decreased dSAMTOR and increased Methionine levels in pathogenic longevity, thus rendering (d)SAMTOR an important component in Methionine-associated disorders, including Homocystinuria(s).

This paper presents some aspects of command and control of the new generation of machines-tools with numerical control. A problem faced by numerical control programmers is related to the length (relatively long) of the programs, with implications in the costs and duration of the manufacturing preparation. A method of reducing the main program and other redundant expenses is the introduction and use of processing cycles and subroutines for automatic calculation of the cutting tool trajectory, a fact that also allows the optimization and simplification of numerical control programming on flexible order manufacturing systems numeric. The method involves the use of predefined cycles and appropriate subroutines in order to improve the efficiency of the programming activity in a balanced way. It is a new and rapid method for optimize the structure of program using the numerical subroutine for command the movement of tool, in our case, with application for turning and milling.

Udder health of dairy cows is related to their productivity and welfare. The period from dry-off to calving and early lactation is crucial. Ultrasonography is a useful and practical tool for the examination of the mammary parenchyma and blood flow. This observational study investigated the relationship between udder echotexture features, blood flow volume (BFVol) in the milk vein, milk somatic cell count (SCC) and daily milk yield (DMY) from late lactation, throughout dry period and consecutive early lactation. Seventeen repeated measurements were performed on 21 Holstein cows. The udder parenchyma was examined with B-mode ultrasonography. Udder echotexture was studied using 15 features: Numerical Pixel Value (NPV), Pixel Standard Deviation (PSD), Skewness, Excess, Contrast, Homogeneity, Correlation, Entropy, Run Percentage, Long Run Emphasis, Grey Value Distribution, Runlength Distribution, Gradient Mean Value, Gradient Variance and Percentage of Non-zero Gradients. Blood flow in the milk vein was examined with spectral Doppler. Linear mixed effects models were employed to investigate relationships between BFVol, udder echotexture features, SCC and DMY, throughout the study period. Our models showed that a 1-kg increase in DMY was associated with a significant increase of 0.25 L/min in the expected BFVol, and that a 1,000,000-cells/mL increase in SCC was associated with a significant BFVol decrease of 0.49 L/min, keeping all other variables constant. Multivariable models showed significant associations between DMY and NPV, PSD and Long Run Emphasis, and between SCC and NPV, PSD, Gradient Mean Value, Homogeneity, Gradient Variance and Entropy. In conclusion, udder echotexture and BFVol in the milk vein are related to SCC and milk yield. Ultrasonography can be used for the comprehensive assessment of udder health in the direction of precision dairy farming.

Tembokrejo Village is one of the villages in Muncar District which has the densest population. The location of Tembokrejo Village is directly adjacent to the Bali Strait which has the potential for a tsunami disaster. With such a large population, the level of risk from a tsunami disaster is very high. Since 2021 in Tembokrejo Village a Disaster Risk Reduction Forum and Volunteers have been formed in the Village. However, over time there have been changes in members. So it is necessary to increase the capacity and knowledge of new volunteers and remind the old members. The method used is qualitative descriptive. The results obtained are many volunteers who still do not have a full volunteer spirit. This can be seen from the activeness and participation of members when handling disaster events in Tembokrejo Village. For this reason, it is necessary to continue to foster a spirit of volunteerism and knowledge from members, who will later become the frontline in disaster management in Tembokrejo Village).

Os resultados da pesquisa contabilizam 1.188 assentos incluindo informações sobre o local onde ocorreu a morte, que dada às características da época, na grande maioria dos casos (85,61%), era também o local de residência da pessoa falecida. Vale ressaltar que os primeiros hospitais surgem apenas no início da década de 1940 e que, tão somente 93 (7,83%) dos óbitos ocorreram nesses espaços. Em 692 casos (58,25%) dos 1188 assentos os registros contaram com atestado médico. Nesses casos, foram identificados 29 médicos presentes na região, entre eles destacam-se: Augusto Cautergiani que atuou desde 1927 e foi responsável por 404 atestados (34,01%) e Ernesto Giorno atuou desde 1930 e totalizando 128 registros (10,77%). De acordo com os dados supracitados, foi possível constatar que havia poucos médicos para atendimento da população e, grande parte dos falecimentos ocorria nas residências e sem receber assistência médica. Por fim, acredita-se que a fundação recente do município e falta de investimento na assistência médica na região podem estar relacionados com precariedade de condições de saúde dos primeiros habitantes do antigo município de Cruzeiro.

In this study, the ability of dilute concentrations of toluene to act as a CO2-soluble asphaltene stabilization agent capable of inhibiting asphaltene precipitation during immiscible CO2 injection was assessed. Phase behavior results indicated that 1,000 to 20,000 ppm toluene could readily dissolve in CO2 at cloudpoint pressures that are well below the formation pressure and typical CO2 minimum miscibility pressure (MMP) values during gas-based enhanced oil recovery (EOR). Single-phase solutions of the modified gas (CO2/toluene) were then combined with asphaltenic oils in oil swelling phase behavior tests to demonstrate that the presence of toluene increased the amount of CO2 that dissolved into reservoir crude oil at a specified temperature and pressure. However, asphaltene precipitation diminished, apparently because the effect of the increased asphaltene solvent strength of toluene was more significant than the increased amount of CO2 (an asphaltene antisolvent) that entered the oil-rich phase. During the injection of CO2/toluene solution into cores initially saturated with crude oil and brine, compared to the injection of pure CO2, asphaltene deposition declined during the injection of CO2/toluene mixtures for asphaltenic volatile and intermediate oils from 3.7 wt% to 0.7 wt% and 5.9 wt% to 1.7 wt%, respectively. Based on the asphaltene particle-size analysis, the CO2/toluene mixtures can stabilize oil particles and simultaneously reduce asphaltene aggregation more effectively than pure CO2.

With the increasing size of social media datasets, it has become a difficult task to explore significant features such as sentiments
from traditional geographical visualizations, because the visual elements of data items always overlap heavily with each other. A
large number of sampling methods have been proposed to reduce the visual clutter and simplify the geographical visualizations.
However, the sentiment features are ignored in the course of sampling which make it easily to misunderstand the sentiments
across local areas. In this paper, we propose a visual abstraction framework for the simplification and exploration of large-scale
geo-tagged social media data, aiming to preserve both the sentiment features and spatial distribution with the sampled social
media data items. Firstly, an agglomerative hierarchical clustering method is proposed to classify social media data into
hierarchical categories based on geographical locations and sentiment attributes. Then, a multi-scale rapid sampling model is
designed to select data items from categories to guarantee sentiment distribution of the local and global areas in the hierarchy.
A rich set of visual interfaces are designed including sentiment tree, heatmap, and ranking view, enabling users to explore and
evaluate the simplified geographical visualizations. We also provide several user-friendly interactions such as the sentiment
wheel for users to conduct deeply geospatial sentiment analysis of large-scale geo-tagged social media data. Case studies
based on real-world datasets and interviews with the domain experts have demonstrated the effectiveness and practicability of
our system in simplifying and exploring large-scale geo-tagged social media data.

Recent technological advancements have enabled spatially resolved transcriptomic profiling but at multi-cellular resolution. The task of cell type deconvolution has been introduced to disentangle discrete cell types from such multi-cellular spots. However, existing datasets for cell type deconvolution are limited in scale, predominantly encompassing data on mice, and are not designed for human immuno-oncology. In order to overcome these limitations and promote the comprehensive investigation of cell type deconvolution for human immuno-oncology, we introduce a large-scale spatial transcriptomic dataset named SpatialCTD, encompassing 1.8 million cells from the human tumor microenvironment across the lung, kidney, and liver. Distinct from existing approaches that primarily depend on single-cell RNA sequencing data as a reference without incorporating spatial information, we introduce Graph Neural Network-based method (i.e., GNNDeconvolver) that effectively utilizes the spatial information from reference samples, and extensive experiments show that GNNDeconvolver often outperforms existing state-of-the-art methods by a substantial margin, without requiring single-cell RNA-seq data. To enable comprehensive evaluations on spatial transcriptomics data from flexible protocols, we provide an online tool capable of converting spatial transcriptomic data from various platforms (e.g., 10x Visium, MERFISH, and sci-Space) into pseudo spots, featuring adjustable spot size. The SpatialCTD dataset and GNNDeconvolver implementation are available at https://github.com/OmicsML/SpatialCTD, and the online converter tool can be accessed at https://omicsml.github.io/SpatialCTD/.
Bearing Fault Diagnosis based on the Local Maximum Peak of Cepstrum
Authors: Wang Jian , Wang Wei , Sun Yongjian , Lu Shizeng
Published: May 2023

In this paper, a bearing fault diagnosis method based on local maximum peaks of cepstrum is proposed. At first, the cepstrum of original signal is calculated. An index named local maximum peak is proposed to extract fault features. Then the binary tree classification method is adopted to complete the feature classification process by setting multiple thresholds or blind areas. The method based on the local maximum peak and its distribution domain is used to determine the threshold. After feature classification, each condition is limited by several limited conditions to complete fault diagnosis. In order to verify the accuracy of the proposed method, test data from practical bearing fault experiments are used in simulation experiments. The results show that the accuracy of the proposed method reached 98.44% and the running time was only 2.1810s, which proved the accuracy and effectiveness. The method has higher accuracy and less running time compared with original cepstrum and other spectral analysis techniques. This approach provides a new idea for fault diagnosis of rolling bearing under condition of constant speed.
Typification of coastal depositional lithofacies with isophysical and isochemical hydro-sand beds via Stratigraphic Modified Lorenz Plots (SMLP): geohydrodynamical implications and valorization of hydrogeological units
Authors: George Nyakno , Thomas Jewel
Published: May 2023

Using an integrated method, four distinct hydraulic flow units (HFUs) were produced from the hydrogeological layers of Ikot Abasi in southern Nigeria. The SMLP, which produced results comparable to those of the discrete rock typing (DRT) technique deploying flow zone indicator (FZI), was used to define and classify the geologic unit (GU) of the aquifer into sections denoted by isophysical and isochemical hydro-sand beds as well as sections with similar hydrodynamic characteristics. The results of an electrical resistivity investigation led to the discovery of three to four economically viable geo-electric strata for groundwater. The goal of this study is to economically valorize the HFUs within the GU for efficient groundwater management. Economic aquifer sand beds in layer two were identified and their resistivity ranged from 26.3-3576.5 Ωm with an average of 764.3 Ωm and thickness ranged from 2.9-262.6 m with a mean value of 61.7 m. Similarly, the estimated ranges of resistivity values and values of thickness of the economic aquifer sand beds in layer three were 58.0-3588.8 Ωm (mean: 840.5 Ωm) and 26.7-212.1 m (mean: 80.0 m), respectively. The result from DRT gave four HFUs, which conformed to the result of SMLP. The four HFUs christened as HFU1-HFU4 are identified by tanθ/slope with each corresponding to 2.083, 1.136, 0.483, and 3.101 respectively. The corresponding value for angle θ in degrees were estimated at 64(superconductor), 47 (conductor), 26 (semi-conductor) and 72 (superconductor) respectively. According to values of ranking efficiency, the delineated HFUs can be classified respectively as good, fair, poor and good. The aquifer system identified to be perfectly heterogeneous, has good hydrodynamic prospect, which is paramount in groundwater flow management and contamination monitoring.
The effect of global and regional solar shading onclimate: A simulation study

Published: May 2023

The potential climate impact of solar geoengineering is examined using climate model simulations by artificially reducing the incoming solar radiation at the top of the atmosphere. Climate scenario simulations indicate that a doubling of atmospheric carbon dioxide (2xCO2) induces a surface temperature rise which is amplified over the poles primarily during the respective winter. The warming also causes intensification and poleward shift of the global precipitation pattern. In our model, a 2.1% globally uniform solar reduction can largely compensate the global mean warming caused by a doubling of CO2. We find that solar shading is efficient to restore the temperature at the region where the background sunshine is strong, regionally at low-latitudes, seasonally during summer. Solar shading would lead to an overall weakening of the global hydrological cycle, resulting in a large-scale drought. A 3.6% solar reduction in the tropics can largely reduce the tropical and global warming as well. However, it reduces the precipitation at the central tropics, while increase the precipitation over the monsoon region. Comparatively, a 14% solar reduction over the poles can effectively prevent the polar summer temperature increase and sea-ice retreat. However, caused by the increased temperature gradient, polar solar shading increases the storm activity at high-latitudes, especially during summer when the solar reduction reaches its maximum amplitude. Our simulations show that solar shading could be an effective way to stabilize the polar cryosphere. Nevertheless, it has a strong impact on the hydrological cycle and provides a heterogenous regional climate signal.
