Infectious mastitis is the most prevalent health problem in dairy cattle that can result in permanent economic losses on dairy farms. The micronised purified flavonoid fraction (MPFF) is a biocompatible active polyphenolic compound derived from flavonoid glycosides which exhibits several antimicrobial, anti-inflammatory, and phlebotonic properties. The goal was to assess the effects of an alternative therapy for mastitis based on MPFF intramammary infusions in late lactation in dairy cows naturally infected by Staphylococcus spp. The California Mastitis Test (CMT scores) was performed to detect mastitis-positive quarters in twelve dairy farms. All cows were screened for immune response by measuring somatic cell counts (SCCs; cells/mL) in milk samples from each quarter. In addition, bacteriological identification, pathogenic bacterial isolates, and total bacterial counts (TBCs; CFU/mL) were assessed before (day 0, last milking day) and after (day 3 post-calving) MPFF application. Antimicrobial sensitivity patterns of the pathogenic isolated bacteria were evaluated. Finally, cure rates (%) were determined for each MPFF treatment. Around 15 mastitis-related genera were isolated. Staphylococcus aureus (25.2%) and coagulase-negative Staphylococci (CNS; 22.4%) were the most prevalent pathogens. No statistical differences were observed in SCCs and TBCs after low, medium, and high MPFF dose administration in S. aureus-positive mastitis cases (p > 0.05). However, differences were observed in SCCs and TBCs after medium and high MPFF dose administration in CNS-positive quarters (p < 0.05). The pathogenic bacteria isolate reduction after MPFF applications showed a dose-response fashion (p < 0.01) while isolates obtained from controls and low MPFF-treated quarters remained similar, irrespective of the pathogen (p > 0.05). Sensitivity patterns were variable, although S. aureus remained resistant, irrespective of the MPFF dose. However, CNS showed a dose-response sensitivity pattern. Finally, the cure rate (%) on day 3 post-partum improved significantly using medium and higher MPFF doses in CNS-positive quarters (p < 0.05). In conclusion, MPFF treatment was found to be more effective for CNS-positive cases in the late lactation due to noticeable dose-specific responses regarding somatic cells, bacterial counts, sensitivity patterns, and cure rates in dairy cattle.

Published: May 2023

Leakage in the impervious layer of a domestic waste landfill seriously pollutes the soil and groundwater. Therefore, it is necessary to carry out rapid nondestructive leakage location detection. In this research, the electrical resistivity tomography (ERT) method and the opposing-coils transient electromagnetic method (OCTEM) were used to detect the leakage location. The inversion sections of both methods showed a clear low–middle–high resistivity spectrum in the longitudinal direction that could be used to speculate the distribution pattern of the upper waste body layer, the bottom impermeable layer, and the lower limestone layer. The leakage area was identified in Zone B of the landfill on the basis of inversion results and drilling verification results. The results indicate that OCTEM and ERT were both sensitive to leakage detection. However, OCTEM had higher longitudinal resolution and more refined inversion results, resulting in more effective delineation for the location of the damage and leakage of the impervious landfill layer, thereby providing a new technical basis for landfill leakage detection.

Published: May 2023

With the increasing demands for higher treatment efficiency, better effluent quality, and energy conservation in Urban Wastewater Treatment Plants (WWTPs), research has already been conducted to construct an optimized control system for Anaerobic-Anoxic-Oxic (AAO) process using a data-driven approach. However, existing data-driven optimization control systems for AAO mainly focus on improving effluent water quality and reducing energy consumption, therefore they lack consideration for the stability of bioreactors. Meanwhile, safety in the optimization control process is still missing, resulting in a lack of reliability in practical applications. In this study, long short-term memory based model-predictive control (LSTM-MPC) with safety verificationis developed for the real-time control of AAO. It is used to optimize the control of aeration volume, internal recirculation, and sludge internal recycle processes for both saving energy and maintaining the stability of the bioreactor operation. To ensure the safety of the control process, this study proposes three rationality verification methods based on historical operation experience. These methods are validated through data from a real-world WWTP in eastern China. The results show that the prediction model of LSTM-MPC is capable of accurately predicting the water quality variables of the AAO system, with mean square error (MSE) close to 2.64 and Nash–Sutcliffe model efficiency coefficient (NSE) of 0.99 on the validation dataset. The combination of LSTM-MPC and rationality verification achieves a stable control trajectory with a 7% reduction in oxygen usage compared to a conventional controller, demonstrating its efficacy as a safe and reliable control strategy for WWTPs.

Published: May 2023

Black-odorous water bodies in the Pearl River Delta have been treated. However, the re-release of nitrogen (N)-containing compounds in sediment can cause a relapse of black-odorous water bodies. Sediment–water ratio (SWR) and hydraulic residence time (HRT) influence pollutant release. Therefore, how to control SWR and HRT during the treatment process has become an urgent problem. This study focuses on the dynamic release of endogenous inorganic N from sediments into overlying water in a river channel of Dongguan City, Guangdong Province. Physicochemical parameters (dissolved inorganic nitrogen (DIN), NH4+-N, NO3−-N, NO2−-N, dissolved oxygen (DO), pH, oxidation-reduction potential (ORP), chemical oxygen demand (COD), Fe and total phosphorus (TP)) of overlying water were monitored under different SWRs (0.71, 0.38, and 0.16) and HRTs (13 days and 6.5 days), and the nitrogen release flux under different conditions was compared. Finally, the correlation and influence pathways among environmental factors were analyzed. The results showed that SWR significantly affected DO, pH, ORP, and sediment N release fluxes while prolonging HRT-promoted denitrification. DIN → NO2−-N → DO pathway had a total effect of 19.6%, and DIN may promote low DO concentration via NO2− oxidation. Maintaining reasonable SWR and HRT can reduce the release of inorganic N from sediment into the overlying water. This study provides a theoretical basis for controlling black-odorous water bodies.

The interaction of surface water and groundwater is important in the ecology of coastal basins, affecting hydrological conditions, oxygen regime, carbon, and nutrient exchange. This study demonstrates a dynamic connection between the salt-wedge region and its underlying aquifer in the eutrophic estuary. In winter, this estuary is covered with ice, and the river flow is at its lowest; that is why the specific response to groundwater discharge is best marked in this season. Groundwater admixture was detected in the salt-wedge region by highly active radium isotopes: 223Ra—4.80 ± 0.42 dpm 100 L−1, 224Ra—55.37 ± 1.1 dpm 100 L−1, and 228Ra—189.71 ± 4.66 dpm 100 L−1. The temperature of groundwater and river water was about +4 °C and 0 °C, respectively; that of seawater was −1.6 °C, and temperature increased up to +2.3 °C in the surface water–groundwater interaction region. Groundwater admixture is accompanied by a lower level of oxygen concentration of 52 μmol/kg; at that time, the maximum oxygen concentration in the salt-wedge region was 567 μmol/kg. In waters with a high activity of radium isotopes, there was a maximum partial pressure of CO2—4454 μatm at the range 100–150 μatm in the salt-wedge region and also observed extremum of NH4+, NO2−, and dissolved phosphorus. The surface water–groundwater interaction through anoxic sediment can form localized anaerobic areas despite the general oxygen supersaturation of eutrophic estuary waters and also cause local recycling of nutrients from bottom sediments.

Illegal sand mining has been identified as a significant cause of harm to riverbanks, as it leads to excessive removal of sand from rivers and negatively impacts river shorelines. This investigation aimed to identify instances of shoreline erosion and accretion at illegal sand mining sites along the Chambal River. These sites were selected based on a report submitted by the Director of the National Chambal Sanctuary (NCS) to the National Green Tribunal (NGT) of India. The digital shoreline analysis system (DSAS v5.1) was used during the elapsed period from 1990 to 2020. Three statistical parameters used in DSAS—the shoreline change envelope (SCE), endpoint rate (EPR), and net shoreline movement (NSM)—quantify the rates of shoreline changes in the form of erosion and accretion patterns. To carry out this study, Landsat imagery data (T.M., ETM+, and OLI) and Sentinel-2A/MSI from 1990 to 2020 were used to analyze river shoreline erosion and accretion. The normalized difference water index (NDWI) and modified normalized difference water index (MNDWI) were used to detect riverbanks in satellite images. The investigation results indicated that erosion was observed at all illegal mining sites, with the highest erosion rate of 1.26 m/year at the Sewarpali site. On the other hand, the highest accretion was identified at the Chandilpura site, with a rate of 0.63 m/year. We observed significant changes in river shorelines at illegal mining and unmined sites. Erosion and accretion at unmined sites are recorded at −0.18 m/year and 0.19 m/year, respectively, which are minor compared to mining sites. This study’s findings on the effects of illegal sand mining on river shorelines will be helpful in the sustainable management and conservation of river ecosystems. These results can also help to develop and implement river sand mining policies that protect river ecosystems from the long-term effects of illegal sand mining.

Authors: Deng Huan , Wei Hongyan , Chen Lizhu , Li Shujie , Liu Hongxu , Lu Hai
Published: May 2023

Biochar is a widely available carbon-based material that has been used for soil remediation and sewage treatment. However, in recent years, biochar has received more attention as a conditioning agent to improve the dewatering performance of sewage sludge. The sludge from the secondary sedimentation tank of wastewater treatment plants has high microbial activity and poor dewatering performance, which poses a challenge to sludge dehydration. Biochar and modified biochar can be injected into sludge as a skeleton to effectively reduce sludge compressibility, increase permeability, and release bound water, thus improving the dewatering performance of sludge. In this review, the preparation and characteristics of biochar are described, the current methods of sludge dewatering and the properties of sludge are introduced, and the research on the application of biochar in sludge conditioning is summarized. In addition, the existing problems and future development directions of biochar in sludge conditioning are discussed.

Along with the rapid development of space technology, extraterrestrial exploration has gradually tended to further-distanced and longer-termed planet exploration. As the first step of an attempt for humans to build a perpetual planet base, building a lunar base by in situ resource utilization (ISRU) will drastically reduce the reliance of supplies from Earth. Lunar resources including mineral resources, water/ice resources, volatiles, and solar energy will contribute to the establishment of a lunar base for long-term life support and scientific exploration missions, although we must consider the challenges from high vacuum, low gravity, extreme temperature conditions, etc. This article provides a comprehensive review of the past developing processes of ISRU and the latest progress of several ISRU technologies, including in situ water access, in situ oxygen production, in situ construction and manufacture, in situ energy utilization, and in situ life support and plant cultivation on the Moon. Despite being able to provide some material and energy supplies for lunar base construction and scientific exploration, the ISRU technologies need continuous validation and upgrade to satisfy the higher requirements from further lunar exploration missions. Ultimately, a 3-step development plan for lunar ISRU technologies in the next decade is proposed, which consists of providing technological solutions, conducting technical verification on payloads, and carrying out in situ experiments, with the ultimate aim of establishing a permanent lunar station and carrying out long-term lunar surface scientific activities. The overview of ISRU techniques and our suggestions will provide potential guidance for China’s future lunar exploration missions.

This research is a quantitative research and the aim of this research is to empirically examine the influence of environmental policy, environmental pollution, environmental energy, and environmental finance on earnings quality and profitability, leverage, and company size as control variables. Earnings quality is measured using real earnings management as a measurement.This study uses secondary data, namely non-financial companies listed on the Indonesia Stock Exchange for the  period during 2019-2021 . The total sample in this study was 198 samples using the panel data regression analysis method and using data analysis with STATA. The research results show that environmental policy, environmental pollution, environmental energy, and environmental financial  no significant effect on earnings quality. But there is a significant and positive effect on the control variables including: profitability, company size and debt ratio on earnings quality. The limitation of this study is that the population is non-financial companies and only measures the disclosure of sustainability reports only from pollution, energy, finance and policy. The practical implication of this research is that the more sustainability report disclosures made by companies, including: policies, pollution, energy and finance, no significant effect on the quality of earnings in companies listed on the IDX, and the increasing profitability, debt ratios and company size, the higher earnings quality, so that investors can consider profitability, company size and debt ratio in investment decisions because one of the considerations of investors is profit. The original value of this research is that this research measures more specific environmental reporting disclosures including: environmental policy, environmental pollution, environmental energy, and environmental financial and earnings quality measurement in this study uses real earnings management with the Cohen and  Zarowin (2010) model which is still rarely used.

Published: May 2023

This study aims to investigate the legal implications of unregistered waqf land and the protection available to it. The research adopts a descriptive and normative legal research approach to analyze the legal framework surrounding waqf in Indonesia. The findings show that the government has enacted laws and regulations, such as Law no. 5 of 1960, Government Regulation No. 28 of 1977 concerning Waqf of Owned Land, and Law Number 41 of 2004 concerning Waqf, to ensure that waqf assets are legally protected and registered. According to positive law, the waqf pledge deed is considered an authentic deed that can be used as evidence in resolving future disputes regarding waqf land. The involvement of witnesses in the waqf pledge process is essential to guarantee the protection of waqf land. Despite the existing regulations, there are still unregistered waqf lands that need legal protection. The research reveals that legal protection for unregistered waqf land is available in Indonesia. However, the absence of registration and certification for waqf land creates uncertainty and makes it vulnerable to misuse by parties who are not responsible for the legal nature and purpose of waqf. Therefore, it is important to continue promoting the registration of waqf assets to ensure their legal protection and prevent any future disputes. The implications of this research contribute to the ongoing discussions on waqf land registration and provide a basis for further research in this field.

Published: May 2023

The attention to branding, from theorists as well as from practitioners, had remained at a very high level for the 2000s and 2010s. Many new branches of branding theory have emerged, and place branding was among them. Actually, place branding has become an umbrella term, a generic definition for three areas of study and practice: nation branding, region branding, and city branding. Every year, new scientific, journalistic, business articles, and books on place branding emerge, there are even several specialized periodicals devoted to this field of branding. This study aims to identify the most relevant and effective symbol of the Ukrainian capital city Kyiv as a tourism brand. Questionnaire surveys and the content analysis of literature and mass media are used. Key segments and sub-segments of the target audience of Kyiv tourism branding are determined, as well as the key factor of influence on the formation of the opinion regarding the tourism symbols of Kyiv. The most common popular symbol is compared with the real resources of the city. Thus, a set of relevances is found appropriate for the development of effective branding of Kyiv.

Authors: Mustafin Farhad M.
Published: May 2023

The aim of the work is to analyze the historical events that led to the formation of statehood among the Kalmyks. For that, the history of the formation of statehood among the Kalmyks in the Volga region in the XVIIth and early XVIIIth centuries is examined. Many historian researchers have addressed this topic, but nevertheless, many issues of the history of Kalmyk statehood remain controversial. Since the topic of the formation of the Kalmyk statehood has its own understatements and hitherto unexplored areas, the need for its full disclosure is still relevant. In the process of research, different scientific methods were used: The method of diachronic analysis, the method of historical periodization, mental modeling, and also the retrospective method. The policy of the Kalmyk Taishi with the Russian state was a means of achieving stability within the Kalmyk society, an accelerator of the formation of Kalmyk statehood in the Volga region. The research concludes that among the many reasons for the migration of Kalmyks to the Volga region, one can single out the main one: the fact that the Kalmyks felt the need for territorial space to create their sovereign state.

Balkan Peninsula Diaspora appeared in Kazakhstan at the end of the XIX century. Firstly, the Bulgarian nationality moved, and then Greeks moved. Among the peoples of the Balkan Peninsula, the fate of the Greeks and Bulgarians is typically common for Kazakhstan. The fact that the Balkans people collided with the land of Central Asia was comprehensively influenced by political, economic, and ideological factors. Adapted to the nature and economy of the new region, the Balkan ethnic groups have retained their identity. Today, the fourth generation of these ethnic groups lives in independent Kazakhstan as a fully functioning Diaspora of Balkan people. Problems of their resettlement and arrangement are one of the topics that have not been studied in history despite being one of the most important in migration and resettlement questions of this territory. In this research work the history of Balkan ethnic groups in Kazakhstan was analyzed on the basis of archival and scientific materials.

Published: May 2023

To explore the application of traditional machine learning model in the intelligent management of pigs, in this paper, the influence of Principal Components Analysis (this method is simply referred to as PCA) pre-treatment on pig face identification with Support Vector Machine (this method is simply referred to as SVM) is studied. By testing method, the kernel functions of two testing schemes, one adopting SVM alone and the other adopting PCA+SVM, were determined to be poly and Radial Basis Function, whose coefficients were 0.03 and 0.01, respectively. With individual identification tests carried out on 10 pigs respectively, the identification accuracy was increased to 88.85% from 83.66% by the improved scheme, also the training time as well as testing time were reduced to 30.1% and 20.97% of the original value in the earlier scheme, respectively. It indicates that PCA pre-treatment had a positive effect on improving the efficiency of individual pig identification with SVM. It provides experimental support for the mobile terminals and embedded application of SVM classifiers.

One of the main factors in the poultry house is maintaining a standardized microclimate. The quality of the product output in the final result depends precisely on the quality indicators of the air parameters. Poultry during its maintenance requires significant efforts and technological solutions. In this regard, authors improved microclimate system in air environment of the poultry house by installing exhaust fans on the side wall in a total number of 8 units. CFD modeling using ANSYS Fluent is a powerful tool for predicting the air flow scheme in a poultry house and is considered an alternative to experimental studies. Based on the obtained results of CFD modeling, it was established that the valves located at a height of 330 mm from the ceiling work most efficiently. Pressure drop for the inlet valves is 45.85 Pa. Air velocity at the inlet of the supply valves is equal to 9.17 m/s. Air velocity at a height of 0.7 m from the floor level varies within 0.57 m/s, the temperature is 9.91 °С.
