Published: October 2023

An ambitious reduction in greenhouse gas emissions is set by the political initiative �The European Green Deal� and �Fit for 55� package. The municipalities, which carry out the strategic management of the district heating systems, will have to ensure the sustainable development of the territory in a way that includes a significant increase in energy efficiency both in the building stock and in the related district heating system.
The aim of this research is to study and develop an easy-to-use methodology and an appropriate web-based application for sustainable management of the urban heating system, which would allow a quick and at the same time accurate and objective analysis of the potential and benefits of the different building renovation depths and corresponding heating system renovation variants in a given area during the pre-design stage, as well as compare them according to their efficiency.
A tree data structure is chosen as the most suitable algorithm, allowing creation of hierarchies of the necessary depth and complexity. Urban (root) level combines many renovation projects to create a dynamic functional model of the specific heating system and for initial modelling the overall impact of various renovation variants � heat consumption and primary energy savings, reduction of CO2 emissions, changes in costs and investments to be performed. At the 2nd - project level � the development of concrete projects and their options takes place. Each project option is a possible heating solution; the attributes of the option define benefits of this project. At the 3rd � component level � heat balances of components (buildings and heat system (DH or local)) are created on the basis of key data of their main elements. The last, 4th level ensures entering and editing thermal, constructive, and financial data on the main elements of heating system components.
Developed management methodology and tool based on the data from real buildings and heating systems shows achievable energy consumption and primary energy savings, reduction of CO2 emissions, takings into account heating energy tariff and renovations investments. Achieving the goal means the serious scientific novelty in the management science and evaluation of the climate policy implementation, as well as the new technological know-how and innovation in data processing.

Published: October 2023

This paper focuses on introducing new procedures for control processes in the area of quality monitoring and the progress of the construction of linear structures, such as roads, railways, or engineering networks. It emphasizes automation and streamlining of processes, which includes efforts to reduce manual labor and increase efficiency through digitization. Digitization is a key element of this approach, as it allows for easier transfer and analysis of data, leading to progress and more accurate evaluation of outputs. This process is important in the context of dynamic development and growing service requirements in the field of surveying and geodetic work in the construction sector. The development of legislation and the goal of digitizing public administration are the main factors determining the need for these new procedures. The digitization of public administration aims to improve the efficiency and transparency of public services, which aligns with the objectives of this article. The result of these innovative procedures should not only be a reduction in costs for human activity and manual labor but also an increase in the accuracy and reliability of evaluated outputs. This should lead to better decision-making and planning in the construction sector, potentially bringing significant time and resource savings. This contribution is supported by the Operational Programme Enterprise and Innovations for Competitiveness APLIKACE project number CZ.01.1.02/0.0/0.0/21_374/0027275 Research and Development of an Innovative Data Building Warehouse (BDW) Line to Ensure Quality and Process Control in Construction and Maintenance.
CONCENTRATION OF LUNAR PLAGIOCLASE FOR SOLAR CELLS FABRICATION. AN ISRU CONCEPTUAL ARCHITECTURE
Authors: Jamanca-Lino Gustavo
Published: October 2023

Because of the incoming mission of Artemis on the Moon, the extraction of water, oxygen, and metal from the lunar regolith is necessary, which involves intensive power requirements. To keep a mining unit operation running continuously, a technical solution known as the Tall Lunar Tower (TLT) claims to be able to capture sunlight 93% of the time through a solar panel structure. The composition of a typical panel is 76% glass, 10% polymer, 8% aluminum, 5% pure silicon, and 1% other metals. Fortunately, we just need to transport polymers, wire, and minor components from Earth because the regolith on the Moon contains large amounts of silicon and aluminum oxides. This article presents an ISRU architecture to provide plagioclase ore concentrate, the main mineral for the extraction of aluminum and silicon, detailing aspects such as the engineering challenges and the technological solutions for excavation, transport, and processing; all these calculations are based on a hypothetical construction and deployment of TLT at the South Pole. Processing techniques such as screening and magnetic separation are discussed to evaluate their advantages and drawbacks to obtain a concentrate of 70% plagioclase with 18% of global recovery.

Published: October 2023

Objectives: The aim of this study was to investigate the effect of different cognitive functions on acoustic voice parameters by recording the use of cognitive functions during extended /a/ phonation in young adults. Patients and Methods: This study was conducted with a total of 31 participants (8 males, 23 females, mean age: 22.3±1.1 years; range, 18 to 30 years) between June 14, 2023 and August 23, 2023. The mean fundamental frequency (F0), jitter (local), jitter (rap), shimmer (local), shimmer dB, and mean harmonics-to-noise ratio values were analyzed as acoustic voice parameters in a total of 186 voice recordings taken in six tasks, including normal and other five tasks (visual attention, language, auditory memory, visual memory, and working memory). Results: A statistically significant difference was found between the acoustic parameters of the six tasks (p<0.001). Shimmer dB showed a statistically significant difference between the auditory memory task and normal state, visual attention and normal state, and working memory and normal state (p<0.05). Conclusion: Different cognitive functions, especially auditory memory, visual attention, and working memory, may have an effect on acoustic voice parameters. Therefore, cognitive functions can be evaluated to identify deficiencies in the relevant cognitive area, and working on these cognitive functions together with voice therapy may shorten the therapy process.

Abstract
This research aims to analyze the effect of porous asphalt clogging on drainage capacity through surface runoff and permeability parameters. Buton rock asphalt pure extraction is used as a binder to increase the quality of the mixture. The study simulated the condition before and after the occurrence of porous asphalt clogging with variations in sediment load, gradation, and rainfall intensity. Determination of the gradation through trial process with limit condition according to ASTM D7064/D7064M − 08 (2013). The simulation used falling head and rainfall simulator tools. The test results show that the sediment load affected the decrease in infiltration capacity of porous asphalt. The infiltration capacity of porous asphalt with VIM of 20.67% can decrease up to 22% when pores were clogged by sediment of 780 gram/m2. Rain intensity of 110 mm/hour only restore the ability to drain water by 11%. There was no surface runoff on any of the mixtures under both normal and sediment clogged pore conditions. Among three porous asphalt mixture designs, mixture with highest VIM had the best pore clogging resistance. To produce mixture with high VIM, the porous asphalt gradation was designed with low uniformity coefficient (Cu).

A microbiota corresponde ao conjunto de microrganismos, como bactérias, arqueas, fungos e vírus, os quais estão presentes no corpo humano. O trato respiratório, juntamente ao intestino, a pele, o trato urogenital e a cavidade bucal, representam microbiomas complexos. O trato respiratório é dividido, anatomicamente, em trato respiratório superior, o qual é composto por cavidade nasal, seios paranasais, nasofaringe e laringe; e em trato respiratório inferior, formado por traqueia, brônquios, bronquíolos e pulmões; partes que apresentam microbiotas distintas. Por muito tempo, o pulmão de um indivíduo saudável foi considerado um ambiente estéril. Contudo, desde 2010, essa crença tem sido refutada. Além disso, foi descoberto que a microbiota pulmonar apresenta profunda relação com a microbiota intestinal, através do eixo intestino-pulmão. Esse eixo indica relação entre o sistema imune desses dois órgãos, via sistema linfático e corrente sanguínea, atuando na modulação da imunidade e influenciando na susceptibilidade a doenças, como a tuberculose. A tuberculose é uma doença causada pelo M. tuberculosis, e é uma das principais causas de morte em todo o mundo. Em 2019, cerca de 10 milhões de novos casos de tuberculose e 1,4 milhões de mortes foram contabilizados pela OMS. Desse modo, o presente capítulo visa compreender a forma com que a microbiota pulmonar e sua conexão com intestino, via eixo intestino-pulmão, interfere na patogênese da tuberculose, doença de grande relevância epidemiológica, além de reunir informações sobre as alterações da microbiota devido à doença e também relacionar um possível uso de moduladores da microbiota no tratamento da tuberculose.

Authors: Soares Emilaine Maria de Souza Rangel , Ferreira Geraldo de Souza
Published: October 2023

In 2006, Petrobras declared the discovery of reservoirs with significant amounts of high-grade API oil and gas located in a region below the salt layer, called the pre-salt, which extends along the southeast coast, from the state of Espírito Santo to the state of Santa Catarina. As it is a region that has not yet been explored, many doubts prevailed about what this layer would be, how the behavior of the salt works, how this system was formed and how it is possible for the oil to be trapped and be of such good quality in such an extreme and little-known environment, among other questions. This paper aims to present the geological formation of the pre-salt, the history of discoveries and the evolution of hydrocarbon production in the region in a time interval of 15 years.

The problem of nitrogen in modern agriculture
Authors: Gamayunova Valentina , Sydiakina Olena
Published: October 2023

Optimal nitrogen supply to plants, in conditions of sufficient moisture, allows for high crop productivity with high-quality indicators. The aim of this article was to summarize and analyze statistical data on the dynamics of nitrogen input and expenditure from arable land worldwide and in Ukraine, as well as provide practical recommendations for addressing the nitrogen issue in modern agriculture. The research utilized theoretical generalization, comparative analysis, graphical, abstract-logical methods and statistical data from FAOSTAT for the period of 2000-2020. The research results have shown that nitrogen input from mineral fertilizers has been constantly increasing both globally and in Ukraine. In contrast to global indicators, there has been a significant reduction in nitrogen input from manure in Ukraine, as well as a decrease in nitrogen input from atmospheric precipitation and through biological fixation by leguminous crops. The components of nitrogen balance, such as leaching, evaporation, and denitrification, play a significant role in nitrogen expenditure. These expenditure components tend to increase both globally and in Ukraine. The largest share in the expenditure component of all countries worldwide, including Ukraine, is occupied by nitrogen removal by cultivated crops. Calculations showed that the nitrogen balance on arable land, both globally and in most countries across different continents for the researched period, was positive. However, in Ukraine, it was negative for 18 out of 21 years. To solve this problem, practical recommendations are proposed using the best practices and developments of economically developed countries worldwide

Authors: Lindsay Daniel , Whiteman David C , Olsen Catherine M , Gordon Louisa G
Published: October 2023

Objective

To quantify differences, by residential remoteness and socio‐economic status, in health care service use by people diagnosed with invasive melanoma in Queensland.

Design

Benefit incidence analysis of CancerCostMod data, comprising Queensland Cancer Registry data linked with Queensland Hospital Admitted Patient Data Collection (QHAPDC), Medicare Benefits Schedule (MBS), and Pharmaceutical Benefits Scheme (PBS) data.

Setting, participants

Adults (18 years or older) newly diagnosed with invasive melanoma in Queensland during 1 July 2011 – 31 June 2015 and alive three years after diagnosis.

Main outcome measures

Concentration curves and indices quantifying differences by residential postcode‐based remoteness (Australian Statistical Geography Standard – Remoteness Area) and socio‐economic disadvantage (Index of Relative Socioeconomic Disadvantage) in hospital admissions (overall and by type) and use of MBS (overall and by type) and PBS services during the three years following diagnosis of invasive melanoma.

Results

A total of 13 145 adults diagnosed with invasive melanoma during 2011–15 were alive three years after the diagnosis. Public hospital admissions were more frequent for people living in areas of greater socio‐economic disadvantage (concentration index, –0.15; 95% confidence interval [CI], –0.19 to –0.12) or outside major cities (concentration index, –0.10; 95% CI, –0.13 to –0.06); private hospital admissions (concentration index, 0.11; 95% CI, 0.07–0.15) and specialist consultations (concentration index, 0.08; 95% CI, 0.07–0.10) were more frequent in areas of lesser disadvantage and in major cities (private hospital admissions: 0.10; 95% CI, 0.06–0.13; specialist services: 0.07; 95% CI, 0.06–0.09). Differences in other melanoma health care service use by residential remoteness and socio‐economic disadvantage were not statistically significant.

Conclusions

Variation in health care service use by Queenslanders with primary diagnoses of invasive melanoma by residential socio‐economic disadvantage and remoteness were generally minor. Our analysis suggests that access to health care for people with melanoma is fairly equitable in Queensland.

On Materialism, Freedom, and Self-Consciousness
Authors: Garba Tapji ,   DePaul University
Published: October 2023

As a problem for thought, racial slavery is seated at the intersection of moral philosophy and philosophy of nature where the figure of the slave, a being who is wholly determined by external forces, serves as the negative measure of the capacity to make ethical judgments beyond one’s own private inclinations or exercise self-restraint for the sake of the common good. Recent theoretical interventions into our political-ecological predicament tend to split when it comes to the modern autonomous subject.

Heavy metal contamination of soil pose risks and hazards to humans and the ecosystem through. Imperata cylindrica is a fast growing plant and often used for phytoremediation. The plant was tested in different growth media of spiked heavy metal, soil pH and organic matter contents for 60-day. After harvesting, the plant was washed, separated into roots and shoots. The soil samples were digested using 1.0g portion of dried the soil ,10.0cm3 of 1:1 HNO3: H2O, 5.0cm3 of HNO3, 1.0cm3 of  H2O2, and 5.0cm3 of HCl while the plant samples were digested using 0.50g of the powdered sample, 5cm3 of  HNO3 and 2cm3 HClO4. Prior to digestion, each sample were oven-dried at 70°C until it achieved a constant weight, grounded (using mortar and pestle) and milled (using a milling machine). Atomic absorption spectrophotometry was used to analyze the accumulation of cadmium, and lead in roots and shoot of the plant. Bioaccumulation factor (BF), biological accumulation coefficient (EC) and translocation factor (TF) was applied to evaluate the metal translocation ability in the plant. Between soil pH and soil organic matter, the highest total biomass of Cd was found in 300g of organic matter treatment (13.48 ± 2.69 mg/kg), while Pb in basic treatment was 18.09 ± 0.66 mg/kg. The result suggests that soil pH has most effect on Pb; while organic matter in Cd in the phytoaccumulation by Imperata cylindrica. The growth of phytoremediation plants like Imperata cylindrica should be encourage to neutralize the heavy metals pollution.
