A paradigm shift in the preparation of nanoparticles from a chemical synthetic route to the green synthetic method using plant extractives has gained much impetus. This study used Chromolaena odorata leaf extract to prepare zinc oxide nanoparticles (ZnO-NPs). The ZnO-NPs were characterised by spectroscopic, optical and thermal techniques. Thermogravimetric Analysis (TGA) revealed no significant weight loss observed after 550°C for precursor powder which was further calcined using a furnace at 800°C and 900°C to obtain ZnO-NPs. Fourier Transform Infrared Spectroscopy (FTIR) spectroscopy analysis indicated Zn-O stretching between 400 cm-1 to 500 cm-1. UV-Vis spectra show a strong absorption band at 388 nm for both calcination temperatures. Scanning Electron Microscopy (SEM) images showed the irregular shapes of the samples at different calcinations. The X-ray diffraction (XRD) diffractograms showed that the synthesised ZnO-NPs are in a hexagonal wurtzite structure. Studies of the electrochemical performance showed that ZnO-NPs made with Chromolaena odorata extract and calcined at 800oC have better cyclability than ZnO-NPs calcined at 900oC. Due to better cyclability, these ZnO-NPs can be applied as anode material in sodium-ion batteries.

Published: March 2024

Diving has become a common way of performing research in the underwater living world. One of the major problems with diving is the health issues faced by the divers during diving and there comes the need for monitoring diver’s health. This paper mainly focuses on the health monitoring systems for divers by transferring the data using Li-Fi (Light Fidelity). This system senses different health specifications like heartbeat, body temperature and body position. The monitored health specifications are recorded as a database in a memory chip for further analysis. To reduce the power consumption, the system transfers the data to the nearby divers and ships only during the abnormal health issue. The uniqueness of this system lies in its combination of advanced technologies for diver safety, communication, and submarine surveillance. This is crucial for ensuring their safety, especially in challenging underwater environments. This is perhaps one of the most unique aspects. Li-Fi, which uses light to transmit data, is a breakthrough for underwater communication. This system provides real-time data on the diver's condition and an immediate way to request assistance in case of an emergency. By incorporating temperature and gyro monitoring, the system collects valuable data on diver conditions and movements. This data could be analyzed for research or used to improve safety protocols in the future.

Published: March 2024

Abstract. Small-scale temperature fluctuations can play a crucial role in the occurrence of ice clouds. This study analyzes a decade of ice polar stratospheric clouds (PSCs) occurrence obtained from Michelson Interferometer for Passive Atmospheric Sounding (MIPAS/Envisat) measurements. The points with the smallest temperature difference (ΔTice_min) between the frost point temperature (Tice) and the environmental temperature along the limb line of sight are proposed here to identify the location of ice PSC observations. In MIPAS observations, we find approximately 56 % of the Arctic and 28 % of the Antarctic ice PSCs are detected at temperatures above the local Tice based on ERA5 data at ΔTice_min. Ice PSCs above Tice are concentrated around mountain regions and their downwind directions. A backward trajectory analysis deduced from the ERA5 reanalysis is performed to investigate the temperature history of each ice PSC observation. Based on 24-hour backward trajectories, the cumulative fraction of ice PSCs above Tice increases as the trajectory gets closer to the observation point. The most significant change of the fraction of ice PSCs above Tice occurs within the 6h preceding the observations. There is an impact of previous temperature fluctuations on the interpretation of MIPAS ice PSC observations. At the observation point, the mean fractions of ice PSCs above Tice taking into account temperature fluctuations along the backward trajectory are 33 % in the Arctic and 9 % in the Antarctic. The results provide quantitative assessments of the correlation between orographic waves with ice PSCs above Tice based on the Lagrangian model by using MIPAS measurements and ERA5 reanalysis data. Additionally, the observational statistics presented can be utilized for comparison with chemistry-climate simulations.

Abstract. Ocean liming has gained attention as a potential solution to mitigate climate change by actively removing carbon dioxide (CO2) from the atmosphere. The addition of hydrated lime (Ca(OH)2) into oceanic surface water leads to an increase in alkalinity, which in turn promotes the uptake and sequestration of atmospheric CO2. Despite the potential of this technique, its effects on the marine ecosystem are still far to be understood, and there is currently no information on the potential impacts on the concentration and quality of Dissolved Organic Matter (DOM), that is the largest, the most complex and yet the least understood mixture of organic molecules on Earth. The aim of this study is to provide the first experimental evidence about the potential effects of pH peaks, that might be generated by the Ca(OH)2 dissolution in seawater, on DOM dynamics by assessing changes in its concentration and optical properties (absorption and fluorescence). To investigate the effects of liming on DOM pools with different concentrations and quality, seawater was collected from two contrasting environments: the oligotrophic Mediterranean Sea (MedSea), known for its Dissolved Organic Carbon (DOC) concentration comparable to that observed in the oceans, and the eutrophic Baltic Sea (BalSea), characterized by high DOM concentration mostly of terrestrial origin. Ca(OH)2 was added in both waters, to reach a pH of 9 and 10. Our findings reveal that the addition of hydrated lime has a noticeable effect on DOM dynamics in both the MedSea and BalSea, determining a reduction in DOC concentration and a change in the optical properties (absorption and fluorescence) of DOM. Thes effects, detectable at pH 9, become significant at pH 10 and are more pronounced in the MedSea than in the BalSea. These potential short-term effects should be considered within the context of the physico-chemical properties of seawater and the seasonal variability.
Interannual Variations of Terrestrial Water Storage in the East African Rift Region

Published: March 2024

Abstract. The US-German GRACE (Gravity Recovery and Climate Experiment, 2002–2017) and GRACE-FO (GRACE-Follow-On, since 2018) satellite missions observe terrestrial water storage (TWS) variations. Over twenty years of data allow for investigating interannual variations beyond linear trends and seasonal signals. However, the origin of observed TWS changes, whether naturally caused or anthropogenic, cannot be determined solely with GRACE and GRACE-FO observations. This study focuses on the East African Rift region region around lakes Turkana, Victoria, and Tanganyika. It aims to characterise and analyse the interannual TWS variations together with surface water and meteorological observations and determine whether natural variability or human interventions caused these changes. To this end, we apply the STL method (Seasonal Trend decomposition based on Loess) to separate the TWS signals into a seasonal signal, an interannual trend signal, and residuals. By clustering these interannual TWS dynamics for the African continent, we define the exact outline of the study's region. In this area, a TWS decrease until 2006 was followed by a steady increase until around 2016, and Africa's most significant TWS increase occurred in 2019 and 2020. We found that besides precipitation and evaporation variability, surface water storage variations in the large lakes of the region explain large parts of the TWS variability. Storage dynamics of Lake Victoria regulated by the Nalubaale Dam alone contribute up to 50 % of the TWS changes. Satellite altimetry reveals the anthropogenically altered discharge downstream of the dam. It thus indicates that human intervention in the form of dam management at Lake Victoria substantially contributes to the TWS variability seen in the East African Rift region.
Influence of mid-latitude Sea Surface Temperature Fronts on the Atmospheric Water Cycle and Storm Track Activity
Authors: Ogawa Fumiaki , Spengler Thomas
Published: March 2024

Abstract. The climatological mean turbulent air-sea heat exchange maximises along midlatitude sea surface temperature (SST) fronts that anchor midlatitude storm tracks. This implies a crucial role of the air-sea latent heat exchange along the SST fronts on the atmospheric water cycle and storm tracks through the intensification of atmospheric cyclones and their associated precipitation. We investigate the sensitivity of the atmospheric water cycle to the SST front through a set of aqua-planet experiments. Varying the latitude of a zonally symmetric midlatitude SST front, the midlatitude atmospheric water cycle responds through distinct changes in surface latent heat fluxes, precipitation, as well as atmospheric moisture fluxes, whereas the tropical latitudes remain largely unchanged. As storm tracks are self-maintained through the diabatic generation of eddy available potential energy, the position of the storm track is diabatically anchored at the SST front. While the position of the SST front determines the position of the eddy moisture convergence and thus the diabatic heating that energises the storm track, the underlying SST determines the general strength of the water cycle and thus the intensity of the storm track. The strong connection identified between the eddy moisture flux and the SST front implies a diabatic pathway of latent heating to anchor the storm track along SST fronts.

Abstract. Multifaceted regime shifts of Earth's surface are ongoing dramatically and – in turn – considerably alter the global carbon budget, energy balance and biogeochemical cycles. Sustainably managing terrestrial ecosystems necessitates a deeper comprehension of the diverse and dynamic nature of multicomponent information within these environments. However, comprehensive records of global-scale fractional vegetation and soil information that encompass these structural and functional complexities remain limited. Here, we provide a globally comprehensive record of monthly vegetation and soil fractions during the period 2001–2022 using a spatiotemporally adaptive spectral mixture analysis framework. This product is designed to continuously represent Earth's terrestrial surface as a percentage of five physically meaningful vegetation and soil endmembers, including photosynthetic vegetation (PV), nonphotosynthetic vegetation (NPV), bare soil (BS), ice or snow (IS) and dark surface (DA), with high accuracy and low uncertainty compared to the previous vegetation index and vegetation continuous-field product as well as traditional fully constrained linear spectral mixture models. We also adopt nonparametric seasonal Mann–Kendall tested fractional dynamics to identify shifts based on interactive changes in these fractions. Our results – superior to previous portrayals of the greening planet – not only report a +9.35 × 105 km2 change in photosynthetic vegetation, but also explore decreases in nonphotosynthetic vegetation (−2.19 × 105 km2), bare soil (−5.14 × 105 km2) and dark surfaces (−2.27 × 105 km2). In addition, interactive changes in these fractions yield multifaceted regime shifts with important implications, such as a simultaneous increase in PV and NPV in central and southwestern China during afforestation activities, an increase in PV in cropland of China and India due to intensive agricultural development, a decrease in PV and an increase in BS in tropical zones resulting from deforestation. These advantages emphasize that our dataset provides locally relevant information on multifaceted regime shifts at the required scale, enabling scalable modeling and effective governance of future terrestrial ecosystems. The data about five fractional surface vegetation and soil components are available in the Science Data Bank (https://doi.org/10.57760/sciencedb.13287, Sun and Sun, 2023).
Support system for heat pump planning in response to drought conditions
Authors: Kubicz Justyna , Karczewski Maciej
Published: March 2024

Abstract. Access to extensive data enables advanced research on the impacts of climate change, specifically drought, on groundwater resources and their consequential effects on water quality. While scientific studies offer insights into predicting groundwater shortages at a high level, the data often remain inaccessible and incomprehensible to potential users. To bridge this gap, this study proposes a relatively straightforward method for assessing the risk of groundwater availability for heat pump usage. The method involves creating informative color-coded charts illustrating periods of potential excessive groundwater level decline near utilized wells. Additionally, it provides the ability to monitor changes in the risk of groundwater level reduction within a predefined observational period. During droughts, groundwater levels can significantly drop, impacting groundwater availability and potentially reducing heat pump efficiency. This, in turn, may lead to system overheating, decreasing effectiveness, and causing damage. Exceeding critical groundwater levels may result in well infrastructure damage, affecting water quality and energy extraction efficiency. Excessive well exploitation often leads to chemical and mechanical clogging, further influencing well performance. In contrast to commonly used hydrogeological drought indicators, this method focuses on a probabilistic model, simplifying calculations as it only requires historical groundwater level data. By applying statistical tests and distribution functions, the study evaluates the risk of extreme groundwater level reduction. The proposed method categorizes risk into very high, high, moderate, and low levels, providing a practical tool for users and groundwater management. The study area, located in the northwest Eurasian continent, encompasses diverse geological and hydrogeological settings. Utilizing data from 27 groundwater observation points, spanning from 1980 to 2020, the research identifies periods and regions at risk of groundwater depletion. The findings highlight specific points vulnerable to high or very high risks, emphasizing the importance of groundwater management strategies. By analysing monthly, quarterly, and seasonal risk variations and comparing results between the decades 2001–2010 and 2011–2020, the study unveils critical insights into groundwater dynamics. Points such as 15 exhibit pronounced risk increases, indicating potential overexploitation or insufficient replenishment. Notably, certain points display decreasing risks, showcasing positive trends that align with effective groundwater management practices. This comprehensive probabilistic approach provides valuable information for stakeholders, empowering them to make informed decisions in selecting a sustainable energy source.
Seasonal variability of wake impacts on US mid-Atlantic offshore wind plant power production

Published: March 2024

Abstract. The mid-Atlantic will experience rapid wind plant development due to its promising wind resource located near large population centers. Wind turbines and wind plants create wakes, or regions of reduced wind speed, that may negatively affect downwind turbines and plants. We evaluate wake variability and annual energy production with the first yearlong modeling assessment using the Weather Research and Forecasting model, deploying 12 MW turbines across the domain at a density of 3.14 MW km−2, matching the planned density of 3 MW km−2. Using a series of simulations with no wind plants, one wind plant, and complete build-out of lease areas, we calculate wake effects and distinguish the effect of wakes generated internally within one plant from those generated externally between plants. We also provide a first step towards uncertainty quantification by testing the amount of added turbulence kinetic energy (TKE) by 0 % and 100 %. We provide a sensitivity analysis by additionally comparing 25 % and 50 % for a short case study period. The strongest wakes, propagating 55 km, occur in summertime stable stratification, just when New England's grid demand peaks in summer. The seasonal variability of wakes in this offshore region is much stronger than the diurnal variability of wakes. Overall, yearlong simulated wake impacts reduce power output by a range between 38.2 % and 34.1 % (for 0 %–100 % added TKE). Internal wakes cause greater yearlong power losses, from 29.2 % to 25.7 %, compared to external wakes, from 14.7 % to 13.4 %. The overall impact is different from the linear sum of internal wakes and external wakes due to non-linear processes. Additional simulations quantify wake uncertainty by modifying the added amount of turbulent kinetic energy from wind turbines, introducing power output variability of 3.8 %. Finally, we compare annual energy production to New England grid demand and find that the lease areas can supply 58.8 % to 61.2 % of annual load. We note that the results of this assessment are not intended to make nor are they suitable to make commercial judgments about specific wind projects.

The agriculture sector in Pakistan plays its vital role for providing food security and economic stability. Pakistan's agriculture sector comprises various subsectors i.e. crops, livestock, fisheries, and forestry. Agriculture growth is threatened by the growth of these subsectors and the impact of population growth on it. No significant research has been conducted in Pakistan to study the statistical significance of these subsectors and their relationship with population growth. This study analyzes data from 2005 to 2023. Regression analysis is used to identify and to compare the statistical significance of all sub sectors of agriculture growth with population growth rate. Average growth rates found positive for agriculture, major crops, livestock, fisheries, and population, while negative for forestry. Model found good fit with R2 0.936. Major crops, livestock, and fisheries have positive and statistically significant impacts on Pakistan's agricultural growth, with coefficients of 0.316, 0.426, and 0.015, while forestry and population reported negative and statistically insignificant results with coefficients of -0.019 and -0.273. This research laid out good policy decisions aimed at boosting agricultural growth in Pakistan.

The goal of this paper is to classify the unusual and dreadful critiques of the clients over one-of-a-kind products and put up a control analysis version to polarize big amounts of analysis. Our dataset comprises consumer reviews and ratings, which are information we have obtained through user evaluations of Amazon goods. We took the skills from our dataset and developed a large supervised version entirely based on them. These modes not great consist of conventional algorithms mutually with naive bays, linear helping vector machines, and k-nearest fellow resident, but also deep studying metrics which encompass frequent Neural Networks and complication neural networks. We evaluated the correctness of those fashions and got a higher know-how of the inverse attitude earlier to the produce. The initial objective is to describe the situation from the client's perspective and assess the intensity of the emotion. The goal of the second assignment is to build and train a machine learning system that can be used to divide customer evaluations into two categories: excellent and terrible. Regardless of the information that Amazon does now not have an API like Twitter to download evaluation with, it does have links for every assessment on every item for consumption, to theoretically traverse the web page through product IDs. We used Perl script written by way of Andrea Eula to get hold of the evaluation for the stimulation and some poles apart products. The most important script downloads the entire HTML page for the product, and the second searches the record for data about the appraisal, such as the product ID, rating, assessment date, and estimate passage. This study shows that the model had a classification accuracy of 78% and a precision similar to the sympathy and genuine score, but the Kappa do curve was rather low. In the future, more work can be done by improving the key parameters.

Two authors independently excluded articles, extracted data, assessed the risk of bias of each included article, and graded the level of evidence. We conducted a meta-analysis using random-effects model and performed a sensitivity analysis stratifying articles based on the risk of bias assessment, study design, and the outcome measurement.

RESULTS: Twenty-four articles were eligible for inclusion. The highest pooled odds ratio (OR) was found for combined mechanical exposures [OR 1.7, 95% confidence interval (CI) 1.4–2.0], non-neutral postures (OR 1.7, 95% CI 1.4–2.1), lifting/carrying loads (OR 1.6, 95% CI 1.3–1.9), and climbing stairs (OR 1.6, 95% CI 1.1–2.2). The range of pooled OR for the remaining mechanical exposures (eg, standing, walking, kneeling, squatting, and sitting) was 0.6–1.6. Grading the quality of evidence, a moderate level of evidence was found for the combined mechanical exposures and for lifting/carrying loads. The remaining exposure categories were graded as having either low or very low levels of evidence.

CONCLUSIONS: Considerable heterogeneity was observed across the included studies, and high-quality literature using objective exposure measurements is warranted. Despite various limitations affecting the comparability, occupational mechanical exposures seem to influence the likelihood of developing hip osteoarthritis.

The objective of this effort is to quantify the amounts of phenolics and the in vitro antioxidant capacities of Allium sphaerocephalon L. flowers’ hydroethanolic (EOH) and aqueous (AQE) extracts. The two extracts' total phenolic (TPC) and flavonoid content (TFC) were determined spectrophotometrically. Results showed the extraction yield obtained by EOH and AQE were 18.30% and 11.80%, respectively. The EOH gave higher amounts of TPC (12.73±0.91µg GAE/mg DW) and TFC (7.67±0.24µg QE/mg DW) than AQE (TPC = 9.71±0.53µg GAE/mg DW and TFC= 5.68±0.90µg QE/ mg DW). Five techniques were used to train antioxidant activity. The EOH extract had high activity in DPPH radical scavenging capacities and β-carotene bleaching assay, while the AQE extract had high activity in metal chelating ions and reducing power assay. However, both extracts had no different significance in cupric-reducing capacity. A moderate quantity of flavonoids and polyphenols, as well as a satisfactory level of antioxidant activity, were observed in both preparations derived from the flowers of A. sphaerocephalon L., where this activity is not all fully related to the amount of phenolic compounds.

Published: March 2024

Herbal medicines have been widely used throughout history, and due to their decreased possibility of adverse effects when compared to modern drugs, both medical professionals and patients have recognized their superior therapeutic efficacy. A systematic strategy for delivering the elements over time is necessary for phytotherapeutics in order to maximizeadherence of patients and prevent repetitive administration. This might be accomplished by creating novel drug delivery systems (NDDSs) for herbal components. Through lowering toxicity and raising bioavailability, NDDSs contribute to increasing therapeutic efficacy by reducing the need for successive administrations to address non-compliance. Nanosized herbal medication delivery techniques may one day enhance performance and address problems with plant-based medicines. To fight other chronic illnesses, such as diabetes, cancer, and others, the conventional medical system must deploy nanocarriers as an NDDS. The article covers the numerous nano herbal drugs and nano herbal cosmetics currently available on the market, as well as the characteristics, benefits, and drawbacks of nano drug delivery systems.

Authors: Nazish Quasmi Mohammed , Pooja Pooja , Kumar Sumit
Published: March 2024

Parkinson's disease (PD) is a condition of neurodegeneration characterised by the decreased levels of dopaminergic neurons. Some of the physical issues with PD include resting tremors, stiffness, bradykinesia or akinesia, instability, and freezing. Damage to the brain's SN and other regions is present in PD. Reactive oxygen species are important and oxidative stress may be related to the disorder (ROS). There are active components in many herbal treatments that have been found to have antioxidant benefits. Therefore, the importance of herbal remedies in the management of PD cannot be undermind. The major goal of the current review is to examining the Parkinson’s disease pathogenesis (PD) and describes function of several potential herbal extracts on its pathogenesis, which may serve as the foundation for treatment. We also go into the chemical components that are present in each herb and useful in treating Parkinson's disease. These herbs are Mucuna pruriens (MP, kapikacchu), Centella asiatica (CA, Mandookaparni), Bacopa monnieri (BM, Brahmi), Cinnamomum verum (CV, cinnamon), Sida cordifolia (SC, bala), Juglandis semen (JS, walnut), Camellia sinens (CS, green tea), Curcuma longa (CL, turmeric), Withania somnifera (PL, kudzu). Future drug development for the successful treatment of PD may benefit from the findings of the current review.

Published: March 2024

Background: Dermatophytic infections, primarily affecting keratinized tissues such as skin, hair, and nails, pose significant therapeutic challenges. Luliconazole, a novel imidazole antifungal agent, has garnered attention for its efficacy against these infections. This review article aims to synthesize current knowledge on luliconazole, focusing on its chemical properties, mechanism of action, clinical efficacy, and application in treating dermatophytoses. Methods: A comprehensive review of recent studies and clinical trials involving luliconazole was conducted. Key focus areas included its antifungal spectrum, particularly against dermatophytes like Trichophyton rubrum, Microsporum gypseum, and Epidermophyton floccosum, and its pharmacokinetic properties that contribute to its effectiveness in treating dermatophytic infections. Results: Luliconazole exhibits potent activity against filamentous fungi, including dermatophytes. It interferes with ergosterol synthesis in fungal cell membranes, leading to increased membrane permeability and cell death. Formulated as a 1% topical cream and a 10% solution, luliconazole has shown significant efficacy in treating conditions such as tinea pedis, tinea cruris, and onychomycosis. Clinical studies demonstrate luliconazole's superiority over other antifungals like clotrimazole, with higher cure rates and rapid symptom resolution. Furthermore, its unique molecular structure enhances penetration into the nail plate, making it effective against onychomycosis. Conclusion: Luliconazole represents a significant advancement in antifungal therapy, offering a potent and targeted option for dermatophytosis treatment. Its broad-spectrum activity, combined with favorable pharmacokinetic properties, underscores its potential as a first-line treatment for various dermatophyte-related infections. Future research should focus on long-term efficacy, resistance patterns, and potential systemic applications of luliconazole.

Authors: Vyas Amber , Sahu Umakant , Jain Vishal
Published: March 2024

Ayurvedic medications are becoming more and more well-liked and accepted globally because they are inexpensive and have no negative side effects. There is a chance that original medications will be adulterated with substances that chemically or physically mimic raw pharmaceuticals because of the increasing demand for herbal raw materials for the production of various classical as well as phytoformulation. Avipattikar Churna is an excellent Ayurvedic formulation for treating health issues resulting from an imbalance of Pitta dosha, such as acidity, heartburn, and indigestion. These issues might arise from bad eating habits, a sedentary lifestyle, or a lack of physical activity. Avipattikar Churna is also beneficial for ailments affecting the digestive and excretory systems' ability to operate normally. It counteracts the gastrointestinal tract's acid secretion and encourages the synthesis of digestive enzymes, which facilitate food absorption. Acid dyspepsia, often known as indigestion, is a condition marked by burning and sour vomit, nausea, heartburn (retrosternal burning), and burning in the throat. Avipattikar Churna is beneficial in treating these symptoms. The standardisation process, which can be carried out using a variety of methods and advanced techniques, conforms the identity, quality, and purity of herbal pharmaceuticals. The HPTLC method is superior to other methods since it may be used with herbal medications and is inexpensive, simple to use, and repeatable. For the purpose of evaluating the quality of Avipattikar Churna and identifying any changes made to the drug's composition, an HPTLC method has been devised. The existence and quantity of the marker compound in the sample are confirmed by the overlap of all relevant spectra with the marker. A gramme of Avipattikar Churna (AVC) methanolic extract contained 2.51 mg of piperine and 2.70 mg of gallic acid, the marker compounds.
