Published: April 2023

Sabah contributes 4.2 million hectares to the total Heart of Borneo (HoB) areas. Some of the forest reserves in the HoB are newly gazetted as Totally Protected Forest. Hence, their mammal diversity has to be comprehensively documented. This study aims to record the presence of terrestrial mammal species, and assess the prevalence of poaching in selected forest reserves within the Sabah HoB area. A total of 15 forest reserves were surveyed within a 5-year timeframe which recorded 60 terrestrial mammal species, including 21 Bornean endemics. The variation in total enumerated mammal species in the study sites may be derived from unequal sampling efforts, geographical factors and anthropogenic influences. The intensity of poaching within the study sites is high. Though this study is a rapid assessment, it created baseline information for mammal diversity in some of the least studied forest reserves in Sabah, important for conservation of its terrestrial mammals.

Published: April 2023

The work of Dr. Polák done in the field of Treasury centralization has brought greater clarity and empirical rigor to the factors governing Treasury centralization and will be of benefit to academics, practitioners and policy makers alike. Practitioners will find a practical and rigorous assessment of the arguments for centralization and the factors for consideration in the location of centers. While Dr. Polák's work in the field of Treasury centralization is rich, there is no shortage of areas for additional exploration. For example, academics can build upon this work by conducting additional empirical study as to the impact of the location factors - both individually and in concert. Finally, policy makers can gain deeper insights into how to attract and retain regional treasury centers.

Published: April 2023

This article considers the founding and first years of existence of museum in Kolomenskoye. The history of the museum in 1923–1930 is traced basing on a rich archive material from archive of Kolomenskoye museum-reserve, Central state archive of Moscow region and Department of Written sources of State Historic Museum. In this article, the condition of architectural monuments in Kolomenskoye during first years after the revolution and their use by different organizations is described in detail. The administrative struggle of Petr Dmitrievich Baranovskiy for transfer of monuments of former tsar’s estate of 16th–19th centuries to museum is in focus. The author considers difficult issue of museum — church relations at that period and their influence on the attitude of Kolomenskoye dwellers and dwellers of another nearest villages to the museum. The article also touches upon the problem of museum’s security and its existence in conditions of hard criminal situation of first post-revolutionary years. The article indirectly considers the issues of the formation of museum staff and restauration of the monuments. Above the frames of this article are the issues of the formation of the museum’s collection and biographies of its first employees, including the biography of P.D.Baranovskiy, about whom many works have already been written. The actuality of the theme of founding of the museum in Kolomenskoye is due to the forthcoming one hundred anniversary of the museum. At this moment, there are no researches in scientific literature, which could give a holistic view of the founding of the first open-air museum of architectural monuments in Russia in former summer residence of Russian tsars.

Starting from the 2022–2023 academic year, St Petersburg State University of Industrial Technologies and Design will begin lecturing and conducting practiacademic disciplines “Modern Cultural Policy of Russian Federation”. This course has been introduced into the educational process of many Russian universities in connection with the Decree of the President of the Russian Federation “Fundamentals of State Cultural Policy” (2014). State cultural policy is an integral part of Russia’s national security strategy. Within its framework, specific tasks are set and carried out. The article describes the structure of the regulatory framework that forms the state policy of Russia in the field of culture. The normative legal acts that make it up serve as sources of the legal field of the museum sphere. The novelty of the study lies in the method of systematizing the legal documents that underlie the legislation on Russian museums in order to present the foundations of modern cultural policy to students of St Petersburg State University of Applied Arts. The scientific significance lies in the fact that the latest legal acts affecting museum issues are analyzed, interpreted with the comments of the researchers of the issue in order to form students’ understanding that the protection of the common good, including in the field of museums, is associated with the organizational and power activities of the state. This article analyzes separate legal sources of the Russian Federation regarding the state and functioning of the Museum Fund and museums in Russia, in particular, the Federal Law “On the Museum Fund of the Russian Federation and museums in the Russian Federation”.
The effectiveness of chlorine dioxide gas in portable personal disinfectants to inhibit bacterial growth
Authors: Ali Firdaus , Lestari Dwi Lintang , Putri Marsya Dyasthi , Azmi Khalidah Nurul
Published: April 2023

Disinfectants, especially air disinfectants, are necessary to prevent the potential spread of pathogens (bacteria and viruses) in the pandemic era and minimize the spread of pathogens. Some of the commercial disinfectant products that are often used generally contain chlorine dioxide (ClO2) gas. This study tested the effectiveness of two different commercial disinfectants, a liquid stick disinfectant and a powder disinfection card, to carry out the disinfection of pathogenic bacteria in the environment. These two disinfectants were used as a medium for releasing chlorine dioxide gas which has a much stronger bactericidal effect. In the form of liquid stick, ClO2 is more effective in the disinfection process rather than in the form of powder. The effectiveness of the liquid disinfectant in inhibiting the growth of pathogenic bacteria is influenced by the temperature and the area of the open space covered. Considering that the release from both disinfectants used is very small (0.002 ppmv/h), it takes a small area to ensure that the disinfection process runs effectively.

With looming global water-related issues, the monitoring of water quality for household and industrial consumption has become more pertinent. Rivers in nearby towns serve as primary water sources for Ekpoma town. 123 samples of stored river water were collected from 41 sampling locations and physical properties – pH, electrical conductivity (EC), salinity, temperature, and total dissolved solids (TDS) – were measured in situ using the Hanna edge® Multiparameter EC/TDS/Salinity Meter-HI2030. Atomic absorption spectrophotometry (AAS) was used to detect and measure the concentration of potentially toxic metals (PTMs): Al, Cr, Cu, Fe, Mn, Ni, Pb, and Zn. The measured concentrations were compared to the WHO, US EPA, and NSDWQ regulatory standards, and a spatiotemporal health risk analysis was performed using HERisk software. Twenty-five percent of the tested samples contained PTM concentrations within the allowable regulatory limits. Spatiotemporal health risk analysis showed that 98.8% of the cumulative carcinogenic risks (CRcum) were entirely from Pb contamination via oral ingestion. PTM concentrations in the samples suggest the degradation of river water quality due to agricultural activities, crude oil exploration activities, and soil composition in the region. Best management practices (BMPs) and treatment processes for the removal of detected contaminants are recommended to improve water quality.

Authors: Vashist Komal , Singh K. K.
Published: April 2023

Floods are catastrophic natural disasters that cause a substantial toll on human lives, infrastructure, and the economy. Structural and non-structural measures are developed for planning flood mitigation strategies. Flood inundation mapping is valuable information for decision-makers and authorities to develop flood mitigation strategies and resource allocation. This study uses the HEC-RAS 2D model for flood inundation mapping in the Krishna River Basin. Digital elevation models (DEMs) of 12.5 and 30 m resolutions were used to model the inundation map. The study also investigated the effect of change in upstream boundary data on the inundated area. The simulated results with 12.5 m resolution DEM are found in good agreement with the validation data and conform to the inundated areas with the available reports. This study proves the 2D capabilities of HEC-RAS and helps the experts with better management practices.
Modification of a plant-scale semi-centralized wastewater treatment system to enhance nitrogen and phosphorus removal from black water

Published: April 2023

Owing to the low ratio of chemical oxygen demand to total nitrogen (SCOD/TN), effective removal of nutrient pollutants from black water is difficult. In this study, to enhance nitrogen and phosphorus removal from such wastewater, a series of operational modification strategies was investigated and applied to a plant-scale semi-centralized system used for black water treatment. The results showed that 21 mg Fe3+/L was the optimal dosage for the chemical-enhanced pretreatment process, achieving average removal efficiencies of 51.1 and 74.1% for organics and phosphorus, respectively, with a slight enhancement in nitrogen removal by 2.3%. However, nitrogen and phosphorus removal could be further enhanced to 88 and 96%, by the addition of carbon sources in the post-anoxic zone of the reversed anaerobic–anoxic–aerobic process. Contrastingly, neither the addition of carbon sources in the pre-anoxic zone nor the prolongation of the time for pre-denitrification could significantly improve the nitrogen and phosphorus removal efficiencies. Furthermore, reducing the aeration intensity promoted simultaneous nitrification and denitrification in aerobic reactors, thereby making it a potential energy-saving method for system operation.

Authors: Shi Changfeng , Shang Teng , Zhi Jiaqi , Na Xiaohong
Published: April 2023

To explore the impact of new urbanization development on industrial water utilization efficiency, the epsilon-based measure model and the entropy method were used to calculate the industrial water utilization efficiency and the development of new urbanization based on the panel data of 30 provincial cities in China from 2011 to 2020. Then the spatial Durbin and the panel threshold models were constructed to explore the spatial spillover and threshold effects of new urbanization development on industrial water utilization efficiency. The results show that there are large regional differences in the development of new urbanization and industrial water utilization efficiency. New urbanization development has a positive spillover effects on the improvement of industrial water efficiency. The promotion effect of new urbanization development on industrial water efficiency is affected by the level of new urbanization development, thus showing different results. According to the findings, it is recommended that local governments at all levels should increase their efforts to build new urbanization. And boost high-level and high-quality development of towns and cities while promoting the rationalization of industrial structure and optimizing resource allocation, thereby improving the efficiency of industrial water utilization.

Published: April 2023

As doenças cerebrovasculares (DCBV) são a segunda maior causa de morte no Brasil, e a primeira causa de incapacidade do mundo, sendo a principal delas o Acidente Vascular Encefálico (AVE). Esse trabalho tem o objetivo de avaliar o número de mortes dessa patologia entre os anos de 2009 a 2018, a fim de se obter um panorama da realidade nacional. Os números dos óbitos foram coletados do departamento de informática do Sistema Único de Saúde do Brasil (DATASUS), e esses dados foram relacionados com as regiões geoeconômicas do país (Centro-Oeste, Norte, Nordeste, Sul, Sudeste), idade e sexo. O estudo identificou um aumento de menos de 1% no número de óbitos, correspondendo à 642 mortes, no final dos 10 anos de pesquisa. No entanto, houve uma redução de seu percentual em relação às mortes gerais no Brasil. Além disso, o AVE se manteve como a patologia que mais mata dentre as estudadas, e em relação às regiões socioeconômicas, o número de óbitos nas regiões Norte, Nordeste e Centro-Oeste cresceram, enquanto nas regiões Sudeste e Sul, diminuiram. Ademais, concluiu-se durante o estudo, que quanto maior a idade, maior o número de óbitos por DCBV, a morte de indivíduos com 75 anos ou mais corresponde a aproximadamente 50% do total, e esses óbitos são levemente mais prevalente no sexo masculino. Portanto, é importante que medidas de atenção primária, focadas na prevenção, sejam intensificadas através de melhorias no controle dos fatores de risco que influenciam na incidência das DCBV no Brasil.
Molecular Connections between DNA Replication and Cell Death in
β-Amyloid-Treated Neurons
Authors: Caraci Filippo , Fidilio Annamaria , Santangelo Rosa , Caruso Giuseppe , Giuffrida Maria Laura , Tomasello Marianna Flora , Nicoletti Ferdinando , Copani Agata
Published: April 2023

Background:

Ectopic cell cycle reactivation in neurons is associated with neuronal death in
Alzheimer’s disease. In cultured rodent neurons, synthetic β-amyloid (Aβ) reproduces the neuronal
cell cycle re-entry observed in the Alzheimer’s brain, and blockade of the cycle prevents Aβ-induced
neurodegeneration. DNA polymerase-β, whose expression is induced by Aβ, is responsible for the
DNA replication process that ultimately leads to neuronal death, but the molecular mechanism(s) linking
DNA replication to neuronal apoptosis are presently unknown.

Aim:

To explore the role of a conserved checkpoint pathway started by DNA replication stress, namely
the ATM-ATR/Claspin/Chk-1 pathway, in switching the neuronal response from DNA replication
to apoptosis.

Methods:

Experiments were carried out in cultured rat cortical neurons challenged with toxic oligomers
of Aβ protein.

Results:

Small inhibitory molecules of ATM/ATR kinase or Chk-1 amplified Aβ-induced neuronal
DNA replication and apoptosis, as they were permissive to the DNA polymerase-β activity triggered
by Aβ oligomers. Claspin, i.e., the adaptor protein between ATM/ATR kinase and the downstream
Chk-1, was present on DNA replication forks of neurons early after Aβ challenge, and decreased at
times coinciding with neuronal apoptosis. The caspase-3/7 inhibitor I maintained overtime the amount
of Claspin loaded on DNA replication forks and, concomitantly, reduced neuronal apoptosis by holding
neurons in the S phase. Moreover, a short phosphopeptide mimicking the Chk-1-binding motif of
Claspin was able to prevent Aβ-challenged neurons from entering apoptosis.

Conclusion:

We speculate that, in the Alzheimer’s brain, Claspin degradation by intervening factors
may precipitate the death of neurons engaged into DNA replication.

Published: April 2023

BACKGROUND

Numerous studies have identified risk factors for physical restraint (PR) use in older adults in long-term care facilities. Nevertheless, there is a lack of predictive tools to identify high-risk individuals.

OBJECTIVE

We aimed to develop machine learning (ML)–based models to predict the risk of PR in older adults.

METHODS

This study conducted a cross-sectional secondary data analysis based on 1026 older adults from 6 long-term care facilities in Chongqing, China, from July 2019 to November 2019. The primary outcome was the use of PR (yes or no), identified by 2 collectors’ direct observation. A total of 15 candidate predictors (older adults’ demographic and clinical factors) that could be commonly and easily collected from clinical practice were used to build 9 independent ML models: Gaussian Naïve Bayesian (GNB), k-nearest neighbor (KNN), decision tree (DT), logistic regression (LR), support vector machine (SVM), random forest (RF), multilayer perceptron (MLP), extreme gradient boosting (XGBoost), and light gradient boosting machine (Lightgbm), as well as stacking ensemble ML. Performance was evaluated using accuracy, precision, recall, an F score, a comprehensive evaluation indicator (CEI) weighed by the above indicators, and the area under the receiver operating characteristic curve (AUC). A net benefit approach using the decision curve analysis (DCA) was performed to evaluate the clinical utility of the best model. Models were tested via 10-fold cross-validation. Feature importance was interpreted using Shapley Additive Explanations (SHAP).

RESULTS

A total of 1026 older adults (mean 83.5, SD 7.6 years; n=586, 57.1% male older adults) and 265 restrained older adults were included in the study. All ML models performed well, with an AUC above 0.905 and an F score above 0.900. The 2 best independent models are RF (AUC 0.938, 95% CI 0.914-0.947) and SVM (AUC 0.949, 95% CI 0.911-0.953). The DCA demonstrated that the RF model displayed better clinical utility than other models. The stacking model combined with SVM, RF, and MLP performed best with AUC (0.950) and CEI (0.943) values, as well as the DCA curve indicated the best clinical utility. The SHAP plots demonstrated that the significant contributors to model performance were related to cognitive impairment, care dependency, mobility decline, physical agitation, and an indwelling tube.

CONCLUSIONS

The RF and stacking models had high performance and clinical utility. ML prediction models for predicting the probability of PR in older adults could offer clinical screening and decision support, which could help medical staff in the early identification and PR management of older adults.

Recommendation Machine for Avoiding Health and Environmental Hazards by Segregating Medical Wastes – A Survey
Authors: Janani M. , Saravanan M. , Santhiya V.
Published: April 2023

Abstract: A growing amount of medical waste needs to be physically segregated. We are recommending a medical waste segregation device for it. The primary goal of this project is to suggest the segregation of waste in municipal offices of India, where the majority of debris is separated using rag pickers which primarily separate the trash from hospitals, which are harmful and dangerous containers made up of toxic metals, by hand. Unfavourable linger leads to health properties such as tuberculosis, tumour, and poisoning metals, which may result in a lower standard of living, decreased longevity, and other side effects. An automated medical waste segregation device is being offered to solve this issue. In medical facilities like hospitals and clinics, this is helpful. India generates 62 million metric tons of waste each year, of which 45 million are disposed of in ways that are dangerous to the environment and human health. Waste management must be effective in intelligent cities. The study proposes an Internet of Things (IoT)-based garbage system that separates waste from various streams, including wet and dry, plastic, paper, metal, and glass. Establish a management system that will improve the chances of recovery and subsequent recycling. The process is simple to control because the system uses an Arduino microcontroller. This separation system's phases include an infrared sensor, an inductive proximity sensor, a raindrop sensor, a photoelectric sensor, and a separation bin. The sensor on each piece of waste detects it and directs it to a specific container for additional processing. The isolated data status will be available in the cloud for monitoring and management

Physico-Chemical Studies on Crude Oil of Western Onshore
Authors: Mendhe Aishwary , Patel Jinal , Nagar Ashish
Published: April 2023

Abstract: Crude oil is a complex mixture of hydrocarbons with non-metallic elements such as sulphur, nitrogen, oxygen, and other elements. Hydrocarbons are chemicals that are mostly composed of the elements carbon and hydrogen. Crude oil comprises a variety of hydrocarbon molecules that fall into three categories: alkane, cycloalkane, and aromatic. Crude oil is distinguished by a number of chemical and physical features that play an essential role in the oil industry. These qualities are critical in making decisions in the exploration and production of crude oil. Characteristics like density, specific gravity, API gravity, water content, and sulphur content, to name a few, contribute value to the price of crude before it is transported to markets and refineries, so controlling these parameters significantly saves damage to infrastructure like pipelines and refineries. As a result, the study of physical and chemical properties becomes crucial for the petroleum industry. The current work deals with the investigation of physico-chemical characteristics of crude oil of Western onshore.

Abstract: We have many state-of-the-art museums around the world to display various forms of physical art. But with the rise of digital art like NFTs, we are still lagging behind in our ways to display them. Displaying them on a website is not enough as they do not guarantee their authenticity and can easily be forged. Digital art needs a digital environment to be displayed without compromising security and reliability and should also provide a world-class environment for its viewers
