Published: November 2024

Banana stems have the potential to be used as filter media in the laundry wastewater treatment process. Laundry wastewater will contain hazardous substances that have the potential to pollute the environment if it is not treated adequately before disposal. Considering the fact that banana stems have a high hygroscopic capacity and cellulose content which is capable of absorbing inorganic chemicals, the use of banana stems as a filter media is considered a realistic option. The research method used is the filtration reactor method, and there are differences in the amount of time invested and the thickness of the banana stem, which can range from 20 to 40 centimeters. There were differences in the decrease in the parameter values of pH, COD, TSS, phosphate, and MBAS with variations in the thickness of the banana stem media. The largest decrease in pH observed occurred at a media thickness of 40 centimeters. Based on the research results, it was found that there was variation in the extent to which parameters were reduced overall. A one-day soak is the most effective way to reduce the severity of these properties. In addition, research findings show that banana stems are not effective enough in processing laundry wastewater.

Authors: Hlukhoveria M
Published: November 2024

Purpose. Development of a technological scheme for the processing of ash and slag waste from coal-fired thermal power plants. The methods. The ash and slag dumps of thermal power plants are made up of the main components - slag, ash and unburned coal particles, drawing up an appropriate scheme for the extraction of coal particles allows the development of an effective scheme for the processing of ash and slag outputs of thermal power plants. The slag is separated from the fly ash by classification on a screen. Next, the method of extracting fuel mass from fly ash is used - the flotation method, based on the selective fixation of coal particles on the surface of air bubbles in the flotation chamber, with subsequent extraction of coal particles into a foam product. The mineral part of the ash cleaned from the fuel mass is ready for use in the road construction industry. Findings. A technological scheme for the processing of ash and slag waste of coal-fired thermal power plants has been developed, which makes it possible to obtain slag, high-quality coal concentrate, and the mineral part of ash. The originality. For the first time, a mathematical model was developed for forecasting indicators of enrichment of ash and slag waste of coal-fired thermal power plants by the flotation method. To predict beneficiation indicators, it is necessary to use three disclosure values: the initial ash content of the coal fraction (Aпd), the number of coal grains (PРЗ), the number of rock grains (PНЗ), provided that the separation characteristics of the beneficiation equipment are experimentally determined in advance. On the basis of the developed mathematical model of forecasting indicators of ash slag waste enrichment, an appropriate flotation scheme for effective extraction of fuel mass was drawn up, which made it possible to develop a technological scheme for processing ash slag waste of coal-fired thermal power plants. Practical implementation. The developed technological scheme for the processing of ash and slag waste makes it possible to obtain slag with a yield of 3.11% suitable for filling industrial roads, coal concentrate with a yield of 25.75% with an ash content of 21.80% can be used as a secondary fuel for thermal power plants or as a raw material for production solid fuel briquettes, as well as the mineral part of ash with a yield of 71.14% with an ash content of 98.10%, which can be used in the road construction industry.
On the provenance of stone artefacts from the excavation materials of the zaporozhian Nekhvoroshchansky monastery of the Dormition of the Mother of God
Authors: Nikitenko I , Starik O , Netecha M
Published: November 2024

Purpose. To determine, according to the data of petrographic analysis, the probable provenance of the raw materials of stone artefacts, namely, the fragments of tools and building stone of the Cossack times and the Late Bronze Age that were found during the archaeological excavations in the territory of the former Zaporozhian Nekhvoroshchansky Monastery, as well as to connect the results obtained with historical context. Methods. The study of the raw material of stone artifacts was carried out by the method of petrographic analysis using a polarizing microscope. The provenance was determined by comparing the obtained petrographic characteristics of the studied samples with similar rocks according to the data of geological materials. Findings. The studied samples were represented by a part of a stone tool of the Early Modern period and two fragments of building material from the cultural horizon of the Late Bronze Age. According to the results of the petrographic analysis, it was established that the tools of the Cossack period were made of hornblende diorite, and the samples dated to the Bronze Age were represented by sandstones with siliceous and carbonate cement, respectively. Regarding the origin of the raw material of the Cossack period artefact, it was found that the diorite manifestations in the zone of the Middle Dnipro megablock of the Ukrainian Shield are geographically closest to the site of the excavation. The sandstone with siliceous cement is most similar to such rocks of the Oligocene-Miocene Poltavska series, which are widespread in the region. The sample of sandstone with carbonate cement was most likely formed in the zone of groundwater emergence, has a Quaternary age and could well be of local origin. The originality. For the first time, a petrographic study of stone artefacts from the territory of a Zaporozhian Nekhvoroshchansky Monastery was carried out. The facts of the supply of sandstones of the Poltavska series from the Samara River Valey during the Late Bronze Age and diorites from the Dnipro Valley during the Zaporozhian Cossack period to the Oril River Valey have been established. Practical implementation. The obtained data can be used when writing scientific works on the history and archeology, as well as educational literature.

Authors: Rukhlov A , Rukhlova N , Kyrychenko M
Published: November 2024

Purpose. To determine the main indicators of the power consumption profiles of the main ventilation fans of coal mines under the condition of regulating their performance using controlled electric drive systems based on semiconductor elements. The methods. The methods of operations research were used to analyse technological processes in terms of compliance of the actual power consumption profiles of the main fans with their expected operating modes. The methods of mathematical statistics were used to determine the statistical parameters of the electrical loading diagrams of the main ventilation fans of coal mines. Findings. A statistical analysis of typical power consumption profiles of the main fans of coal mines with different electric drive systems has been carried out: a synchronous motor with a high-voltage frequency converter, an induction motor based on the asynchronous-thyristor cascade system, and a synchronous motor with ‘classical’ rotor excitation control without semiconductor elements. The feasibility of using adjustable electric drive systems to control the performance of main ventilation fans in terms of reducing active power consumption has been confirmed. However, at the same time, the consumption of a significant amount of reactive power is shown, which is inherent for systems based on semiconductor elements, regardless of the motor type (synchronous or asynchronous). Originality. The statistical analysis of the actual daily power consumption profiles of the main fans of coal mines with different controlled electric drive systems has shown that the standard deviation of the active load does not exceed 1% of the rated power of the drive motor and does not depend on its type (synchronous or asynchronous). Practical implementation. The practical value of the work is in determining the actual consumption of reactive power by the systems of controlled electric drive based on semiconductor elements. It shows its significant level, which should be provided by appropriate filter-compensating devices on the power supply buses of the motors of the main ventilation fans.

Authors: Zabolotnyi K , Temchenko V
Published: November 2024

Purpose. The development of a methodology for conducting verification calculations of adjustable butterfly valves using computer modeling and analysis technologies. Implementation of the developed methodology for the DXO DN 400 PN 2.5 valve. The methods. The geometric modeling of the DXO DN 400 PN 2.5 valve is carried out using the SolidWorks software. The obtained solid assembly is used to create computational models to investigate the valve’s performance. The SolidWorks Flow Simulation 2016 module is used for modeling hydrodynamic processes, while SolidWorks Simulation is used to study the valve’s stress-strain state. This combination of software products was chosen due to their high level of integration. The parametric model created in SolidWorks is used for calculations in Flow Simulation. The resulting kinematic and dynamic parameters of the fluid flow are transferred to Simulation for analyzing the stress-strain state of the structure. Findings. Using the example of the DXO DN 400 PN 2.5 valve, a methodology for conducting verification calculations of adjustable butterfly valves has been substantiated. Computational models have been developed to establish flow pressure on the valve in SolidWorks Flow Simulation and the stress-strain state of the valve in SolidWorks Simulation. A series of calculations for various positions of the valve control element was performed. The dependence of the stress dynamicity coefficient on the disk rotation angle was analyzed. It was shown that hydrodynamic flow has a significant impact on the stress-strain state of the structure. The originality. For the first time, a methodology for conducting verification calculations of adjustable butterfly valves using a parametric model created in SolidWorks, with the transfer of calculation results to the SolidWorks Flow Simulation and SolidWorks Simulation packages, has been proposed. It was demonstrated for the first time that maximum stresses in the disk tube and stiffening ribs of the DXO DN 400 PN 2.5 valve occur at angles between the disk plane and the plane perpendicular to the pipeline axis, which are 45° and 60°, respectively. Practical implementation. The presented methodology simplifies the search for an optimal valve design among a wide range of possible design options.

The Indonesian Music Museum stores various music collections in the form of cassettes, compact discs, vinyl records, and music-related books. This self-managed museum has the potential to become an institution that stores musical works from various countries. Management has been carried out properly, starting from inventory of collections to registration, but still manually. The implementation of the Senayan Library Management System (SLiMS), which is an open source based application, is one solution for managing collections more quickly and making it possible to access them remotely. The method used in this research is a qualitative study using observations and interviews so that it can produce an appropriate management system for the museum. The main informants are museum managers who are considered to understand the metadata needs of their museum collections. All results of observations and interviews are used as guidelines in determining any changes to the applications used to manage collections at the Indonesian Music Museum. This research produces an open source application-based museum collection inventory system. Several changes and adjustments were made to this application so that it could be implemented in the museum. Terms referring to library collections were changed and adapted to the use of terms relevant to music collections. The grouping of collections based on music genres and artists' regions of origin which is usually carried out by the museum is still maintained to become the characteristic of this museum itself. The Indonesian Music Museum can implement this application in a sustainable and long-term manner. Using this system helps the museum to obtain data records of collections and their movements, as well as inventory data on collections currently owned.

O leitor desta obra irá encontrar uma discussão crítica e detalhada acerca das teorias contratualistas como protagonistas da formação do Estado e de suas instituições, as quais por meio das políticas públicas e de seus subgrupos, regulamentam o funcionamento da sociedade política. A política educacional vem a se constituir um desses subgrupos, a qual normatiza a gestão do ensino público. A gestão do ensino público por sua vez, deve seguir elementos essenciais como a democracia e a participação, pois são esses elementos que respaldam as ações públicas e fundamentam a gestão democrática da educação. A gestão democrática da educação como política educacional ganha amparo legal e popular, por meio da implementação dos planos de educação. Nos municípios, essa política torna-se plena com a implementação do Plano municipal de Educação. Neste trabalho ele é concebido como o documento basilar da educação formal, pois é ele que estabelece e cria as estratégias para romper com a displicência educacional e estabelece uma rede de ensino qualitativa e participativa.

Introduction

The intention to dropout and dropout is a problem still unresolved in higher education institutions.

Objective

To estimate the differences in the levels of engagement, motivation and academic satisfaction according to (a) intention to dropout and (b) students who remained with those who dropped out. Method: non-experimental designs were used. Two studies are reported, study 1 involved 3,256 students and study 2 involved 2,110 students. The Utrecht Work Engagement Scale Student Test, the Academic Self-Regulation Scale and the Academic Satisfaction Scale were used. The intention to dropout was measured with 3 items and the final dropout data was taken from the official register of students who dropped out of university.

Results

There are significant differences in the levels of engagement, autonomous motivation and satisfaction between the students who remained and those who dropped out of the university.

Discussion

Students who dropped out in the 3rd semester presented lower levels of academic engagement, motivation and academic satisfaction than those who remained. The intention to dropout and lower levels of these cognitive-motivational variables may contribute to the identification of students at high risk of dropping out. These results contribute to unveiling key variables for the educational transformation of Higher Education in the 21st century.

Background

The triglyceride-glucose (TyG) index is a surrogate indicator of insulin resistance. Therefore, we aimed to determine the association between TyG index and heart failure (HF) with preserved ejection fraction (HFpEF) in patients with coronary heart disease (CHD) and to explore whether such associations would be modified by different metabolic states.

Methods

Among 107,301 CHD patients, 62,794 were included to analyze the relationship between the TyG index and HF. Among them, 8,606 patients who had undergone echocardiography were included to identify different types of HF, including HF with reduced ejection fraction (HFrEF), HF with intermediate-range ejection fraction (HFmrEF), and HFpEF. Among them, 1896 patients were diagnosed with HFpEF. Logistic regression was used to analyze the relationship between the TyG index and HFpEF in CHD patients. In addition, the association between TyG index and HFpEF according to sex, age, blood lipids, and blood pressure was assessed.

Results

A baseline analysis of CHD patients divided into four groups according to the tertile level of the TyG index showed significant differences in the related parameters between the groups. In the multi-adjusted models, the TyG index was significantly associated with the risk of HFpEF (odds ratio [OR]: 1.17; 95% confidence interval [CI]: 1.09–1.25). After adjustment for multivariates, TyG index levels for T2 (OR: 1.33; 95% CI: 1.16–1.52) and T3 (OR: 1.52; 95% CI: 1.32–1.74) were associated with increased OR in HFpEF. In addition, the TyG index of CHD patients was significantly associated with HFpEF in older adults aged > 60 years (OR: 1.20; 95% CI: 1.11–1.29), hypertension (OR: 1.27; 95% CI: 1.17–1.37), and dyslipidemia (OR: 1.15; 95% CI: 1.08–1.24). Moreover, the OR (OR: 1.23; 95% CI: 1.11–1.36) in women is higher than in men (OR: 1.17; 95% CI: 1.02–1.22, indicating a stronger association between TyG index and HFpEF in women.

Conclusions

Our findings demonstrated a significant association between TyG index and HFpEF in CHD patients. Furthermore, TyG index was independently associated with HFpEF in hypertension, dyslipidemia, and older patients (aged > 60 years). In addition, the association between the TyG index and HFpEF in CHD patients differed according to sex.
