Published: June 2024

Summary
During an acid fracturing treatment, the preflush and spent acid injected by multistage alternate injection will enter the matrix; this part of the aqueous phase entering the matrix will cause serious water blocking damage during crude oil production, hinder the migration of crude oil in the matrix, and reduce the well productivity. There is a large amount of small-sized pore throats in low-permeability bioclastic limestone reservoirs. The small-sized pore throats are important channels for hydrocarbon flow and are more vulnerable to water blocking under the effect of capillary pressure. The multistage alternating injection of microemulsion acid is a key technology to unlock the commercial potential of low-permeability porous limestone reservoirs, which has the advantages of high acid conductivity, long action distance, less solid residue, and low water blocking damage. This technology has demonstrated good usability in field tests, and the relevant laboratory studies mainly focus on understanding the stimulation effect of microemulsion acid through macroscopic core experiments. But there is still no clear explanation at the microscopic level for why this system can expand its invasion range and mitigate the water blocking damage. To evaluate the effect of microemulsion acid in limestone reservoirs and provide a reference for its application, the properties and mechanism of this system are studied in this paper, while the systems commonly used in the acid pressing process (spent acid without cleanup additive, spent acid added with cleanup additive, and spent emulsified acid) are selected as the control group. According to the characteristics of multimode pore throat in limestone reservoir, a special micromodel with CaCO3 coating is developed. The microfluidic research is carried out to visually present the dynamics of multiphase flow during different spent acids invasion and flowback processes. The cleanup mechanism of microemulsion acid was revealed, while highlighting its application advantages through comparative analysis.

Abstract

In India, tomato cultivation is highly threatened by the invasive South American tomato leaf miner, Tuta absoluta Meyrick. Application of chemical insecticides is the most commonly recommended practice for the management of T. absoluta. Hence, considering the ill effects of the pesticides on environment, natural enemies and human health, alternate ecofriendly strategies for the management of T. absoluta has to be worked out. Keeping this in view, present investigation was carried out to design a biointensive module for the management of T. absoluta on tomato. Laboratory bioassays with four isolates of B. bassiana and one isolate of M. anisopliae indicated that the B. bassiana isolate (Bb 112) had the lowest LC50 values (0.45 x 105 and 0.77 x 106 spores ml− 1, respectively) and was highly virulent against both the eggs and larvae of T. absoluta. Among the parasitoids, T. achaeae was found to be more effective (55.00 and 23.27%) followed by T. Chilonis (40.60 and 3.70%) and T. japonicum at (23.60 and 2.32%) at 1:1 ratio against freshly laid eggs of T. absoluta. Based on the laboratory findings, two field trials viz., one at Madampatti and another one at Thondamuthur village of Coimbatore district, Tamil Nadu were conducted during 2020–2021 to evaluate the efficacy of three biointensive modules in comparison with two modules exclusively with insecticides and an untreated control with four replications. Among the modules tested, Module 3 (Pheromone trap @ 40 / ha + T. achaea @ 5 cc / ha + spinetoram 11.7% SC @ 500 ml /ha + cyantraniliprole 10.26 OD @ 150 ml / ha) recorded the highest per cent reduction in larval population (60.02 and 63.08%) and fruit damage (60.58 and 64.96%). The effective BIPM Module 3, identified from the above experiments validated under farmer’s field in Thodamuthur during 2021–2022 showed its consistent efficacy in checking the T. absoluta population (62.48%) and fruit damage (65.87%) followed by farmer’s practice. The tomato fruits harvested from the experimental plots analyzed through QuEChERS method revealed detectable levels of cyantraniliprole residue @ 0.01 mg / kg of tomato and spinetoram @ 0.01 mg / kg of tomato in the plots treated with BIPM module. However, the residue levels did not exceed the CODEX MRL of 0.06 mg / kg of tomato for spinetoram and 0.5 mg / kg of fruiting vegetables for cyantraniliprole. While, in farmer’s practice, the residue level of cyantraniliprole was 0.15 mg /kg of tomato which was 10 fold more than that of the BIPM module.
A pair of Chinese Shang oracle graphs Niu and Yang for certain livestock originate from a pair of Halaf pottery motifs bucrania and mouflons, which spread across prehistoric Old World.

Published: June 2024

Abstract

Utilizing the multiple evidence of genetics, archaeology, iconography, graphemics and philology, this paper discovers two foreign elements Niu and Yang from the Fertile Crescent, in the Shang oracle inscriptions; as well as articulates the dispersal across Europe of the Halaf culture motif pair bucrania and mouflons. These discoveries provide a clue to investigate the relations of several pictograph type writing systems of the Bronze Age Old World. The connection among the Shang graph pair Niu and Yang, the European late Neolithic and Bronze Age abstract motif bucrania, and the Halaf pottery motif pair bucrania and mouflons is disclosed by the shared contents of their meaning: taurine cattle and sheep/goats from the Fertile Crescent. The second prototype of the Halaf motif pair, the back view of the whole body is distinguished from the head view by comparing the motifs with animal images and according to their placement in the evolutionary process. Owing to the same form, the same degree of abstraction, and the same characteristic feature (a pair of huge and curved horns), the Shang graph pair falls in the clusters of those abstract variants of the Halaf motif pair. This coincides with that the Shang graph pair stay outside the category of all the other four-legged animals’ Shang oracle graphs, not only because of the different view types, but also the Shang graph pair’s more abstract form implying their more ancient times.

Published: June 2024

Abstract

Underwater image processing has drawn a lot of interest in recent times since it is a crucial and demanding topic. Compared to the pictures taken in the air, underwater images are of lower quality and typically have a hazy, muted appearance. This study suggests a method for enhancing underwater images that makes use of both the RGB and LAB colour spaces basically focusing on two primary challenges essential for underwater image enhancement- colour and contrast distortion. These basic issues that underwater images face are addressed and handled using different colour spaces. The contrast can be increased using LAB colour space, and its hues can be restored using RGB colour channel. Experiments on underwater images shot in various conditions show that the recommended technique outperforms other cutting edge methods in terms of the final image quality.

Published: June 2024

Abstract

Background
Care robots are expected to be useful in long-term care (LTC) settings to resolve several challenges associated with aging populations. However, their use is still limited and little is known about the factors associated with their adoption. This study aimed to identify the factors associated with the adoption of care robots, using a quantitative analysis of a large sample at the organizational level in Japan.
Methods
We analyzed residential service providers using 3 years of pooled cross-sectional data from the Fact-Finding Survey on Long-term Care Work in Japan. In this survey, care robots were categorized as robots for “Transfer support,” “Mobility assistance,” “Toiletry support,” “Monitoring and Communication,” “Bathing support,” and “Support for LTC workers.” We defined “adoption of care robots” as LTC providers having adopted at least one of the care robots. To identify the characteristics of LTC providers associated with the adoption of care robots, we conducted a multivariable logistic regression comparing providers with and without care robots.
Results
Of the 4,688 LTC providers, 1,250 (26.7%) adopted care robots. The characteristics of LTC providers that were found to be associated with the adoption of care robots were: information and communication technology (ICT) equipment adoption (adjusted odds ratio [aOR] 3.11, 95% confidence interval [CI] 2.45, 3.95), younger average age of care workers (aOR 0.95, 95% CI 0.94, 0.97), large number of employees (aOR 1.008, 95% CI 1.006, 1.010) and appointment of employment management supervisor (aOR 1.61, 95% CI 1.40, 1.85). The primary results were consistent when broken down according to the type of care robot used.
Conclusions
Our findings suggest that care robot adoption is highly compatible with ICT equipment adoption, particularly among younger workers, and among large-scale providers and those with a high awareness of improving employment management indicated by the appointment of an employment management supervisor. This study identified the factors associated with the adoption of care robots at the organizational level and is expected to contribute to realizing the implementation of care robots.

Published: June 2024

Abstract

Introduction: Cerebrovascular autoregulation (CA) is the ability to maintain adequate cerebral blood flow (CBF) over a wide range of arterial blood pressure (ABP). Carbon dioxide (PaCO₂) is a potent vasodilator, but its precise influence on CA remains incompletely understood.
Methods: A porcine cranial window model, in which CBF can be measured directly in the pial arterioles while ABP is mechanically manipulated, is used to investigate the effect of PaCO₂ on CA capacity. Hypercapnia and hypocapnia were induced in 12 male piglets each by adjusting the respiratory rate. Once stable PaCO₂ levels of resp 60 mmHg and 25 mmHg respectively were achieved, ABP was gradually increased in half of the animals or decreased in the other half beyond limits of CA by inflating a balloon in the aorta or inferior caval vein.
Results: Before ABP manipulation, hypercapnia already induced a significant vasodilation (+33.9%) and increase in CBF (+20.5%) whereas hypocapnia did not alter diameter or CBF. Both hyper- and hypocapnia significantly reduced the ability to adjust arteriolar diameters in response to changes in ABP.
Conclusion: During hypo- as well as hypercapnia, narrowing of the CA range with a shorter plateau between upper and lower limit of autoregulation was observed, compared to normocapnia.
Consistency between apatite and zircon petrochronology supports robustness of apatite in fingerprinting igneous processes in porphyry systems

Abstract

Apatite low-temperature thermochronology can be double or even triple dated allowing for a reconstruction of the thermal history of rock from ~ 550 oC to near-surface temperatures. Even though it has disadvantageous U–Th–Pb contents (high Pb contents and low U and Th contents) and an unstable nature, apatite is still regarded to have the same robustness in fingerprinting igneous processes in porphyry systems as zircon, so far as to be replace zircon. Hence, we systematically studied characteristics of morphology, geochronology and geochemistry of apatite hosted in syenogranite and monzogranite intrusive rocks in the large Hutouya skarn deposit, in order to corroborate its potential thermochronological monitoring capabilities like zircon in fingerprinting igneous processes in porphyry systems. In this study, apatite grains can be subdivided into two types, FI-free Apatite I formed in the early less fractionated magma and FI-rich Apatite II crystallized in the late highly fractionated magma stage. We obtained ages of 229.0 ± 6.6 Ma in syenogranite and 224.3 ± 4.5 Ma / 223.7 ± 3.9 Ma in monzogranite from Apatite I of magmatic origins. Zircon grains in the two granites can be classified into three types. Zircon I is characterized by transparent and bright zones, Zircon II by dark and metamict features, and Zircon III by mineral inclusions. Zircon I grains with a magmatic texture of well-developed bright oscillatory zones, are most likely primary magmatic zircon that crystallized early in the evolution of granitic magma, dating results of which are 224.70 ± 0.61 Ma in syenogranite intrusions and 225.75 ± 0.66 Ma / 226.31 ± 0.78 Ma in monzogranite, respectively. The apatite–zircon timing is coincident. Furthermore, apatite trace rare earth element contents in the syenogranite and monzogranite intrusions display a negative-slope chondrite-normalized distribution from La to Lu with strong negative Eu anomalies and weak positive Ce anomalies, with major element contents that are statistically identical with enriched F but poor Cl. Zircon trace element compositions in the two intrusions show consistent and steeply increasing chondrite-normalized REE diagrams from La to Lu with negative Eu anomalies and strong positive Ce anomalies. Accordingly, apatite U–Pb dates and the corresponding in-situ trace element compositions and isotopes can test precise constraints on rock formation ages, temperature, oxygen fugacity, material source, and tectonic background, which can be relatively more robust when used as proxies for magma oxidation state.

Published: June 2024

Abstract

Researchers are increasingly enthusiastic about the THz frequency range, anticipating it will revolutionize communications by enabling high-speed, high-data-rate transmissions. This paper investigates the transmission, absorbance, and shielding effectiveness of various shades of tinted film within the G-band frequency range (220 GHz to 325 GHz). The measurements were conducted using a terahertz time-domain spectroscopy (THz-TDS) system, powered by a femtosecond laser to generate terahertz pulses. Experimental results indicate that films with 100% intensity tint exhibit low transmission values, effectively blocking the terahertz signal. Conversely, for tint intensities ranging from 0% to 95%, transmission values increase with higher tint intensities. The absorbance results show an inverse relationship with transmission, increasing as the tint intensity increases. Additionally, the shielding effectiveness results reveal that films with 100% tint intensity significantly impact terahertz performance, demonstrating more than 30 dB of attenuation.

Abstract

BackgroundInflammatory bowel disease (IBD) is a chronic and relapsing inflammatory disorders of the gastrointestinal tract, and currently the treatment options of IBD remain limited due to its complex pathogenesis. Quercetin (QUE), one of the representative flavonoids with various bioactivities, has many beneficial effects on gut health. However, little is known of its function on colitis. In this study, the protective effects and underlying mechanisms of QUE on colitis were investigated using dextran sulfate sodium (DSS)-induced mice by using 16S rDNA sequencing, immunofluorescence histochemistry, enzyme-linked immunoassay, respectively.ResultOur datas revealed that QUE administration by oral gavage not only ameliorates the symptoms and histopathological change of colitis, but also increases the concentration of mucin2, numbers of goblet cells and the expression of tight junction proteins, including ZO-1, Occludin, and Claudin-1. In addition, we also found that macrophage in colon were skewed to M1 macrophage polarization by DSS treatment, but QUE treatment markedly promoted M2 polarization in mice colon, while the levels of inflammatory cytokines (TNF-α, IL-1β, IL-6 and IL-10) were also changed, and received after QUE treatment. In addition, Immunofluorescence results also revealed that QUE upregulated the Nrf2/HO-1 signaling pathway, while the level of oxidative-stress enzymes (superoxide dismutase, glutathione, and catalase) were also reversed by QUE treatment. Furthermore, 16S rDNA sequencing revealed that QUE treatment partially restored the alterations in the gut microbiota in colitis mice, mainly by increasing the abundance of potentially beneficial bacteria (such as Odoribacter) whereas decreasing the abundance of potentially harmful bacteria (such as Bacteroidaceae and Bacteroides).ConclusionQUE had the capacity to treat colitis by maintaining the mucosal barrier, modulating inflammation, decreasing oxidation stress, and reverting gut microbiota changes. This research provides an ideal, healthful, and sustainable approach for IBD treatment.

Published: June 2024

Abstract

The concentrations of atmospheric pollutants are a serious concern due to their adverse impacts on human health. The ventilation coefficient (VC) is an indicator that measures the dispersion capacity of air pollutants (air pollution potential) in the atmosphere, providing insights into air quality. In this study, we aim to investigate the spatio-temporal variation and trends of VC over the Indian subcontinent using India’s first high-resolution regional reanalysis (IMDAA) and global reanalysis datasets (ERA5) for the period 1980-2019. The spatial pattern of the seasonal climatological mean ERA5 and IMDAA derived VC shows a lower magnitude during winter and post-monsoon seasons, indicating poor air quality over the Indian region, especially in the northern parts of India. We noticed a gradual declination of VC during different seasons, implying increasing surface-level air pollutants and worsening air quality over India. The study further investigates the changes of VC during strong phases of El Niño and La Niña events. The results reveal that El Niño significantly impacts air quality over northern and western parts of India during pre-monsoon and monsoon seasons. At the diurnal scale, the VC exhibits the highest magnitude and variability during daytime due to increased dispersion of pollutants and higher human activities, while remaining low and stable during night due to stagnant atmospheric conditions. These essential characteristics of VC are well represented in IMDAA, albeit with some discrepancies. Furthermore, we have examined the fidelity of a machine learning model-Convolutional Neural Network and Long Short-Term Memory (CNN-LSTM), in predicting the VC for the year 2019 over Delhi city. Various statistical metrics are computed to evaluate the performance of the CNN-LSTM model. The results confirm that the model successfully predicts the VC compared to observations from ERA5.
Response of commodity markets to global warming attention
Authors: Geng Jiangbo , Jiao Anjiao 
Published: June 2024

Abstract

This study used the internet search index on the topic ‘global warming’ as a proxy for the level of public attention to global warming and empirically tested the shock of global warming attention to international commodity markets. The findings indicate that the returns, volatility, and uncertainty of the commodity markets exhibited high sensitivity to global warming attention. Moreover, the findings show that first, global warming attention positively shocked the returns, volatility, and uncertainty of the agricultural market. Second, global warming attention negatively shocked the returns of the fossil energy market but positively shocked the volatility and uncertainty of the fossil energy market. Third, it caused no significant shock to the livestock market. Fourth, it positively shocked the returns of the metal market but did not significantly shock the volatility and uncertainty of the metal market. Therefore, it is imperative for financial regulators and investors to be more aware of climate change attention and its heterogeneous shocks to different commodity markets to prevent and mitigate its adverse consequences.

Abstract

Background
Asthma is a chronic disease that results from complex interactions between multiple environmental and genetic factors. A bi-directional relation is proposed between level of asthma control and mental health. The present study evaluates this relation and investigates the factors associated with either, among Syrian asthmatic patients.
Methods
A cross-sectional study was conducted among 101 asthmatic patients who were attending pulmonology clinics in two central hospitals in Damascus. Patients were requested to fill out the ACT (Asthma Control Test) and GHQ-12 (the 12-item General Health Questionnaire) questionnaires. Data were analyzed using Chi-Square test in SPSS version 26.
Results
We found no significant correlation between ACT and GHQ-12 categories (p = 0.071). More than two-thirds of patients expressed severe psychological problems unassociated to their level of asthma control. Sex had no effect on asthma control nor mental health. However, age was a substantial determinant; as 79.5% of middle-aged patients had uncontrolled asthma (p = 0.040), and from mental health aspect; almost 50% of young patients had severe psychological distress and more than third had evidence of distress (p = 0.007). On the other hand, smoking had no significant impact on ACT nor GHQ-12 scores. Patients with controlled asthma mostly lived in rural areas likewise most patients with severe psychological distress; hence, residence had a crucial influence on both ACT and GHQ-12 scores (p = 0.003, p = 0.056 respectively).
Conclusion
Results of this study show no correlation between asthma control and mental health. Factors that affect both scores include patient’s age and place of residence. This indicates several cofactors influencing asthmatic patients’ general health beside their asthma control level, which must be considered in clinical approach.
