Redes Neurais e Síntese Musical utilizando Conjunto de Dados Sonoros
Authors: Lemos Gabriel Francisco
Published: September 2023

O presente artigo propõe um estudo comparativo entre duas estruturas topológicas de Redes Neurais – Recursive Neural Networks (RNN) e WaveNet – aplicadas à síntese sonora e análise de conjunto de dados sonoros. Avaliou-se o estado da arte dessas tecnologias no campo da criação sonora contemporânea, identificando seus limites técnicos e possibilidades estéticas na aplicação desses sistemas em contextos artísticos. A relevância da pesquisa na implementação desses modelos no campo da criação sonora e no contexto brasileiro se concentra no estudo crítico da adequação das técnicas de aprendizado de máquina na síntese e nas implicações estéticas para a composição contemporânea. No atual estágio da pesquisa, concluímos que a aplicação desses métodos de síntese se encontra aquém de uma utilização profissional, visto que os sons produzidos possuem alto índice de ruído, apresentam baixa resolução e dificilmente mantêm uma coerência composicional no decorrer do tempo das amostras. Ressaltamos também que a implementação desses sistemas no contexto brasileiro é problemática, pois o desenvolvimento desses modelos necessita de acesso a custosos recursos computacionais de alto desempenho. Identificamos, no entanto, que uma alternativa possível para esse problema de acesso às infraestruturas adequadas é a contratação de serviços de processamento via nuvem – mas que, salientamos, são monopolizados por companhias localizadas exclusivamente no Norte Global.

Published: September 2023

The main research paper focuses on the optimal hybrid system using HOMER software in the central plant of Hassi R’mel. Indeed, the system is composed of PV panels, a battery bank, and a diesel engine, all of which are used to supply an industrial load. Hence, the present work proposes a solution to optimize the power generated by the power sources, maximize the photovoltaic source use, and minimize the use of the battery bank and the diesel generator. Moreover, the solution aims to guarantee the safe operation of the system components and continuity in the load power supply. These objectives are performed by the minimization of a cost function, in which the power generation cost, the energetic balance, and the environmental parameters are taken into consideration. Among the five solutions, the most optimal system obtained is PV/Diesel/batteries /Grid. This system consists of 1200 KW PV, an 1100 KW diesel generator, 800 units of battery, and an 1100 KW converter. Therefore, to supply the station with 49% of electricity by PV and 51% by diesel while the reduction of emissions is 60%, and 708020 liters of diesel is saved. Applying the sensitivity analysis also showed that renewable resources have an impact on the sizing of PV. When solar radiation increases, the size of renewable energy decreases and the NPC decreases as well. It can, thus, be illustrated that the PV/diesel/battery system is not fully-optimal. This strategy is recommended for industrial system security since it can be used to ensure systems from an energetic and economic point of view.

Published: September 2023

The circadian rhythm system regulates lung function as well as local and systemic inflammations. The alteration of this rhythm might be induced by a change in the eating rhythm. Peroxisome proliferator‐activated receptor gamma (PPARG) is a key molecule involved in circadian rhythm regulation, lung functions, and metabolic processes. We described the effect of the PPARG agonist pioglitazone (PZ) on the diurnal mRNA expression profile of core circadian clock genes (Arntl, Clock, Nr1d1, Cry1, Cry2, Per1, and Per2) and metabolism‐ and inflammation‐related genes (Nfe2l2, Pparg, Rela, and Cxcl5) in the male murine lung disrupted by reversed feeding (RF). In mice, RF disrupted the diurnal expression pattern of core clock genes. It decreased Nfe2l2 and Pparg and increased Rela and Cxcl5 expression in lung tissue. There were elevated levels of IL‐6, TNF‐alpha, total cells, macrophages, and lymphocyte counts in bronchoalveolar lavage (BAL) with a significant increase in vascular congestion and cellular infiltrates in male mouse lung tissue. Administration of PZ regained the diurnal clock gene expression, increased Nfe2l2 and Pparg expression, and reduced Rela, Cxcl5 expression and IL‐6, TNF‐alpha, and cellularity in BAL. PZ administration at 7 p.m. was more efficient than at 7 a.m.
The Failure of a Pure Patent Market
Authors: Bessy Christian
Published: September 2023

This paper presents an analysis of the movement to make patents a new asset class, and its relative failure. Our thesis is that this creation is largely dependent on the construction of a market devoted to transactions in patents, and not just in technology licenses, and on the emergence of new intellectual property intermediaries akin to finance, whose activity must nevertheless be regulated. Our analysis is based on the various patent valuation conventions that underpin its institutionalization and the variety of its uses.
Translingual practice as a representation of heritage languages and regional identities in multilingual society
Authors: Ding Seong Lin , Goh Kim Leng
Published: September 2023

By drawing attention to the translingual practices in Malaysian Mandarin (MM), this study uses lexical variations as an analytical lens through which the changes in linguistic dimensions can be viewed from a social perspective. We present translingual practice as a communicative, rather than a pedagogical, resource that has broader applied relevance in multilingual society. Two findings are presented. First, we elaborate on how MM is interwoven with translingual words of various heritage languages (HLs)/dialects and major/powerful languages; second, we examine how translingual words varied from or standardised towards Standard Mandarin (SM) over time, by HL and in place/region. We argue that intersection with competing levelling pressures reflects not only a “standardisation” process at schools/in society but can be further interpreted as the decline of local translingual practices and local sounds, suggesting the risk of losing rich ethnic and regional heritage and identities. By giving a voice to marginalised HL speakers, this study goes beyond the description of an unstudied/understudied research site or linguistic phenomenon, implying important aspects of power and inequality and a subtle resistance against dominant policies/discourses. This could be salient for advancing future studies and theories to address efforts in advocating critical language awareness and inclusive policies.
Answerability in computer-assisted language learning: a critical examination of social justice research from a decolonial perspective
Authors: Dizon Gilbert
Published: September 2023

In this conceptual article, the author introduces decolonization as an alternative to social justice frameworks. As stakeholders in second language (L2) teaching, the author stresses decolonization as a means for L2 researchers to work against colonial practices in educational research, which negatively impact historically disenfranchised communities. Specifically, Patel’s (Patel, Leigh. 2016. Decolonizing educational research: From ownership to answerability. New York: Routledge) answerability framework is introduced as a practical method to support decolonization in L2 research. The article is made up of four main sections. The first section explains the concept of settler colonialism and highlights how it is ingrained in educational research. In the second section, the author defines decolonization and distinguishes it from the more popular social justice movement. In the third section, the author summarizes four computer-assisted language learning (CALL) papers which were featured in a recent special issue on the topic of social justice. The author then provides a critical analysis of the reviewed studies from a decolonial perspective in the fourth and final section, while also suggesting ways in which researchers and educators can re-orient their work towards decolonization.
A structural biology view on the enzymes involved in eukaryotic mRNA turnover
Authors: Krempl Christina , Lazzaretti Daniela , Sprangers Remco
Published: September 2023

The cellular environment contains numerous ribonucleases that are dedicated to process mRNA transcripts that have been targeted for degradation. Here, we review the three dimensional structures of the ribonuclease complexes (Pan2-Pan3, Ccr4-Not, Xrn1, exosome) and the mRNA decapping enzymes (Dcp2, DcpS) that are involved in mRNA turnover. Structures of major parts of these proteins have been experimentally determined. These enzymes and factors do not act in isolation, but are embedded in interaction networks which regulate enzyme activity and ensure that the appropriate substrates are recruited. The structural details of the higher order complexes that form can, in part, be accurately deduced from known structural data of sub-complexes. Interestingly, many of the ribonuclease and decapping enzymes have been observed in structurally different conformations. Together with experimental data, this highlights that structural changes are often important for enzyme function. We conclude that the known structural data of mRNA decay factors provide important functional insights, but that static structural data needs to be complemented with information regarding protein motions to complete the picture of how transcripts are turned over. In addition, we highlight multiple aspects that influence mRNA turnover rates, but that have not been structurally characterized so far.

Published: September 2023

Artificial intelligence (AI) is changing many aspects of education and is gradually being introduced to language education. This article reviews the literature to examine main trends and common findings in relation to AI technologies and applications for second and foreign language learning and teaching. With special reference to computer-assisted language learning (CALL), the article explores natural language processing (NLP), data-driven learning (DDL), automated writing evaluation (AWE), computerized dynamic assessment (CDA), intelligent tutoring systems (ITSs), automatic speech recognition (ASR), and chatbots. It contributes to discussions on understanding and using AI-supported language learning and teaching. It suggests that AI will be continuously integrated into language education and AI technologies and applications will have a profound impact on language learning and teaching. Language educators need to ensure that AI is effectively used to support language learning and teaching in AI-powered contexts. More rigorous research on AI-supported language learning and teaching is recommended to maximise second and foreign language learning and teaching with AI.

A Review of the Factors Influencing Variations in the Heartwood Proportion for Solid Wood
Authors: Arisandi Rizki , Marsoem Sri Nugroho , Sutapa Johanes Pramana Gentur , Lukmandaru Ganis
Published: September 2023

Using 146 journals, 6 chapters, 4 reports, 2 books, and a proceeding, this research seeks to investigate the factors that influence variations in the proportion of heartwood. The data were collected through an online search in databases such as Scopus, Science Citation Index, Science Direct, Google Scholar, and ResearchGate with seven search queries, namely heartwood variability, heartwood proportion, tree age of heartwood, growth rate of heartwood, silvicultural treatment of heartwood, as well as genetic and environmental effects of heartwood. By eliminating papers that were out of topic or title, purpose and year of publication, 67 journal articles, 4 chapters, 3 reports, a book, and a proceeding were selected. The review results showed that the amount of heartwood was influenced by its position in the tree, tree variations, such as age, growth rate, and species/genera, as well as the growing conditions, including location and environmental factors. It is also affected by various silvicultural treatments, namely spacing, thinning, pruning, fertilization, and irrigation. These findings indicate that the amount of heartwood is more controlled by the diameter of the wood than the age. Furthermore, several studies reported that the growth rate of sapwood rings was significantly higher than the heartwood rings, which can reduce the quality of solid wood used for construction. Therefore, it is necessary to control the proportion of heartwood through genetics and environmental factors, especially genetics, which has more effects on the growth rate of tree diameter than environmental factors. Previous studies revealed that tree diameter has a weak or negative correlation with other wood properties, such as basic density, color, and wood stiffness, which are generally important in global markets. It is important for breeders to concentrate on using species with superior genetic variations as well, especially the highly demanded traits in further studies.
Strength and Durability Assessment of Self-Healing Bio-Based Composite Concrete under Different Exposure Conditions
Authors: Rajesh A. , Sumathi A. , Gowdhaman D.
Published: September 2023

Cracks in concrete are predestined, and they lay a pathway for water and aggressive chemical substances, which leads to deterioration of concrete ingredients and affects the service life of concrete structures. In the recent years, natural fibers and bacteria species are used to improve rheological properties and to heal concrete cracks. Precipitation of calcium carbonate crystals produced by bacteria in concrete cracks is highly acceptable to increase the mechanical and durability properties. In this research, Bacillus paramycoides species is isolated from concrete efflorescence and is used for self-healing. For bacteria immobilization, natural fibers like coir, flax, and jute are used as suitable carriers. Furthermore, the study on the performance of bacteria in crack healing and strengthening properties is in need for different curing/exposure conditions such as full-wet, wet–dry, saturated normal soil, and saturated marine soil. The performance of bacteria in concrete is estimated by a series of tests such as compressive strength, compressive strength regains, tensile strength, impact strength, sorptivity, and deterioration of concrete under acid curing. Based on the test results, the selected bacteria have the ability to heal crack widths of 0.3–1.1 mm with the average healing rate of 83 %, 92 %, 76 %, and 42.5 % for full-wet, wet–dry, normal soil, and marine soil exposure, respectively. Microstructure studies were investigated for fiber-reinforced concrete and bacteria-immobilized fiber-reinforced concrete to determine the composition of elements formed in calcium carbonate precipitates. In this work, the results suggest that natural fibers can be used as sustainable carrier material for crack healing, strength, and durability improvement in concrete.

Authors: Yang Renhe , Zhang Pengyu , Wang Dongmei , Sun Qian , He Tingshu
Published: September 2023

This article mainly tested and evaluated the carbonation resistance of sprayed concrete mixed with different liquid accelerators, and thus attempted to establish a prediction model for the carbonation depth of sprayed concrete. Firstly, the influence of alkaline liquid accelerator based on sodium aluminate (AR), alkaline-free liquid accelerator based on aluminum sulfate (AS), and alkali-free liquid accelerator based on fluoroaluminate (AF) on carbonation resistance of sprayed concrete was explored. In addition, the porosity and pore structure distribution of ordinary sprayed concrete (OSC), sprayed concrete with AR (SC-AR), sprayed concrete with AS (SC-AS), and sprayed concrete with AF (SC-AF) were analyzed by the mercury intrusion porosimetry. The carbonation depth and compressive and splitting tensile strength also were tested. Furthermore, the scanning electron microscopy was employed to observe the micromorphology of hydration products. The experimental results indicated that the carbonation depth order of sprayed concrete was as follows: SC-AR > SC-AF > SC-AS > OSC. After analyzing the disparity of SC-AR, SC-AS, and SC-AF carbonation depth caused by AR, AS, and AF dosage, the influence coefficients of sprayed concrete carbonation depth were introduced. Finally, the carbonation depth prediction models of SC-AR, SC-AS, and SC-AF were preliminarily established.
The Impact of Chemical Fixation on the Microanatomy of Mouse Organotypic Hippocampal Slices

Published: September 2023

Chemical fixation using paraformaldehyde (PFA) is a standard step for preserving cells and tissues for subsequent microscopic analyses such as immunofluorescence or electron microscopy (EM). However, chemical fixation may introduce physical alterations in the spatial arrangement of cellular proteins, organelles, and membranes. With the increasing use of super-resolution microscopy to visualize cellular structures with nanometric precision, assessing potential artifacts, and knowing how to avoid them, takes on special urgency. We addressed this issue by taking advantage of live-cell super-resolution microscopy that makes it possible to directly observe the acute effects of PFA on organotypic hippocampal brain slices, allowing us to compare tissue integrity in a “before-and-after” experiment. We applied super-resolution shadow imaging (SUSHI) to assess the structure of the extracellular space (ECS) and regular super-resolution microscopy of fluorescently labeled neurons and astrocytes to quantify key neuroanatomical parameters. While the ECS volume fraction (VF) and microanatomic organization of astrocytes remained largely unaffected by the PFA treatment, we detected subtle changes in dendritic spine morphology and observed substantial damage to cell membranes. Our experiments show that PFA application via immersion does not cause a noticeable shrinkage of the ECS in hippocampal brain slices maintained in culture, unlike the situation in transcardially perfused animalsin vivowhere the ECS typically becomes nearly depleted. Our study outlines an experimental strategy to evaluate the quality and pitfalls of various fixation protocols for the molecular and morphologic preservation of cells and tissues.

Published: September 2023

The peatland conservation model is generally developed based on the community. A new education-based conservation model was developed through temporary activities through seminars, workshops or non-formal learning. The aim of this research is to develop and validation a peatland conservation model through interdisciplinary science learning that connects universities, schools and communities in peatland conservation activities. The development of a peatland conservation model went through third stages following interdisciplinary research patterns. Validation was determined by content and empirical validation. The peatland conservation model consisted of three interrelated dimensions in peatland conservation, namely universities, schools and communities. The model was equipped with implementation tools in the field in the form of science learning tools. The form of a peatland conservation model book, teaching practice materials, an environmental literacy questionnaire, and an interdisciplinary thinking performance rubric were developed in this study. The validated aspects included theory, assumptions, and conceptual model representations with the Aiken score was 0.88 as a valid category and the ICC value of 0.457 showed that the reliability was not good. Empirical validation showed that the dimensions of the university, school and community constructs had internal consistency reliability and validity. The relation between dimension that universities had an influence on schools and society, and schools have an influence on society. The peatland conservation model was equipped with practical teaching learning tools that directly connected universities and schools. However, this model was also suitable for non-educational natural sciences courses or pure natural sciences to form interdisciplinary thinking skills and environmental literacy.

Published: September 2023

Lemongrass (Cymbopogon nardus (L.) Randle) plantlets are interesting to be used as tissue culture-based souvenir. The success of plantlet propagation through photomyxotrophic culture is influenced by several factors, including sucrose concentration and light intensity. The research aimed to analyze the effect of sucrose concentration and light intensity on the growth of lemongrass plantlets. This experimental research used randomized block factorial design with two factors, namely sucrose concentration (0 g/l, 10 g/l, 20 g/l, 30 g/l) and light intensity (2000 lux, 3000 lux, 4000 lux, 5000 lux). The variables observed were some parameters of growth and development of plantlet. The data were analyzed with two-way Analyses of Variance and Duncan Multiple Range Test. The results showed that sucrose concentration had significant effect on the number of shoots and leaves of plantlet. The light intensity and the interaction of both factors had also significant effect on the number of shoots and leaves. The most optimal treatments were sucrose of 20 g/l and light intensity of 3000 lux.  The results of this study innovate the tissue culture technique using photomyxotrophic system in order to produce sterile lemongrass plantlets in large quantities.

Published: September 2023

Nanochitosan is a polysaccharide that can be used as a feed additive to improve the chemical quality of eggs. Protein and cholesterol levels are indicators of the chemical quality of eggs that affect egg weight. This study aims to analyze the effect of nanochitosan as a feed additive on improving the chemical quality of eggs in terms of protein content, cholesterol content, egg white weight, egg yolk weight, and duck egg weight. This study was designed in a completely randomized design (CRD) consisting of 5 treatments (0; 2.5; 5; 7.5; 10 g nanochitosan/kg feed) with 5 replications. Treatment of feed was given for 8 weeks. Variables measured included protein content, cholesterol level, egg white weight, egg yolk weight, and duck egg weight. Data was analyzed using ANOVA at 5% significance. The results showed that nanochitosan as a feed additive had a significant effect on increasing protein content, egg white weight, egg yolk weight, egg weight and cholesterol reduction. The conclusion of this study is that nanochitosan can be used as a feed additive that has potential to improve the chemical quality of duck eggs. The novelty of this research is the use of nanochitosan as a feed additive to improve the performance of livestock in increasing protein levels and reducing cholesterol levels in pengging duck eggs. The results of this study are expected to open up opportunities regarding the use of nanochitosan as a feed additive in various other local ducks in Indonesia.

Authors: Hindersah Reginawanti , Asyiah Iis Nur
Published: September 2023

Enzymatic transformation in the cycle of nutrients of Nitrogen (N) and phosphorus (P) in soil can only be carried out by microbes. The latest approach in coffee cultivation is to utilize soil microbes to enhance plant growth, also to reduce the attack of the nematode Pratylenchus coffeae on coffee roots. This exploratory study aimed to observe the attack of P. coffeae and the presence of N-fixing bacteria (NFB) and P- solubilizing microbes (PSM) in the coffee rhizosphere which in turn have the potential to be used as biological fertilizers and bioprotectants of coffee plants. The study was conducted in PT Perkebunan Kalibendo's Arabica and Robusta coffee fields, East Java, on immature plants (IP) and mature plants (MP). This exploration explained that the IP and MP arabica and robusta coffee plantations were attacked by P. coffeae. NFB and PSM were successfully isolated from the rhizosphere of both coffee plantations types. The population of NFB Azotobacter in IP was lower than in MP, but the PSM population in IP rhizosphere was not different from that in MP. Based on morphological and biochemical characterization, three isolates of Azotobacter bacteria, six species of P- solubilizing bacteria (PSB) and six species of phosphate-solubilizing fungi (PSF) were obtained. This exploration confirmed that the microbes involved in the N and P cycle colonized the coffee rhizosphere which was attacked by P. coffeae. Further research is recommended to observe the effectiveness of microbes as biological fertilizers and bioprotectants for coffee plants.

A New Decision Making Method for Selection of Optimal Data Using the Von Neumann-Morgenstern Theorem
Authors: GarcÍa Cabello Julia
Published: September 2023

The quality of the input data is amongst the decisive factors affecting the speed and effectiveness of recurrent neural network (RNN) learning. We present here a novel methodology to select optimal training data (those with the highest learning capacity) by approaching the problem from a decision making point of view. The key idea, which underpins the design of the mathematical structure that supports the selection, is to define first a binary relation that gives preference to inputs with higher estimator abilities. The Von Newman Morgenstern theorem (VNM), a cornerstone of decision theory, is then applied to determine the level of efficiency of the training dataset based on the probability of success derived from a purpose-designed framework based on Markov networks. To the best of the author’s knowledge, this is the first time that this result has been applied to data selection tasks. Hence, it is shown that Markov Networks, mainly known as generative models, can successfully participate in discriminative tasks when used in conjunction with the VNM theorem.
The simplicity of our design allows the selection to be carried out alongside the training. Hence, since learning progresses with only the optimal inputs, the data noise gradually disappears: the result is an improvement in the performance while minimising the likelihood of overfitting.

Comparative Evaluation of a Lower-Dose CBCT Acquisition Protocol for Preoperative Implant Site Assessment in Dry Human Skulls: A Proof-of-Concept Study
Authors: Tadinada Aditya , Proft Bailey , Thacker Sejal , Yadav Sumit
Published: September 2023

Restoration of edentulous sites with dental implants is increasingly becoming a popular choice. Cross-sectional 3-dimensional imaging using cone-beam computed tomography (CBCT) provides a better depiction of the implant site to help the clinician plan the procedure better. In spite of the advantages, radiation dose will always remain a concern. The evolution of lower-dose protocols is ongoing, but whether those acquisition protocols yield comparable diagnostic information is still not well established. The objective of this study was to evaluate the diagnostic efficacy of a low-dose, 180° rotational CBCT acquisition protocol for evaluating a potential implant site in comparison with a conventional 360° rotational acquisition. Ten dentate and partially edentulous dry human skulls providing 82 randomized implant sites—40 in the maxilla and 42 in the mandible—were chosen for this study. Each skull was imaged using a 360° and a 180° rotational acquisition on a J. Morita Accuitomo CBCT scanner. Evaluation of cortical and trabecular bone, height, width, and proximity to critical structures, such as the inferior alveolar nerve canal and the maxillary sinus, were measured. An oral surgeon and an oral radiologist rated the diagnostic efficacy of the scans by evaluating the above characteristics. Statistical evaluation of the data with linear regression showed significant agreement between both protocol measurements. Kappa analyses yielded a good interobserver agreement. In this proof-of-concept study, CBCT imaging using the lower-dose, modified arc, and 180° acquisition protocol shows comparable results to the conventional 360° protocol for preoperative implant assessment.

A sinus floor elevation via lateral window (LSFE) is one of the most widely used bone augmentation procedures for implant therapy in the posterior area of the maxilla. Locating and preparing a correct opening window on the lateral sinus wall is a key step of this procedure. Conventionally, the surgeon designs and locates the window after the flap is reflected based on the information obtained from cone-beam computed tomography (CBCT) images or other diagnostic aids. Nevertheless, in spite of the advancements in CBCT imaging, clinicians may still experience hardships in situating and procuring meticulous access to the maxillary sinus by using CBCT alone. Therefore, in cases requiring an LSFE simultaneous to implant placement, a maxillary sinus surgical guide has been tested and reported to be the amiable method to be utilized as a conjunct to prevent unpredictable consequences according to its application in implying both the direction for the implant and the location of the lateral window. This article presents 3 clinical cases with a fully digital approach to guide the opening of the lateral wall of the maxillary sinus as well as the simultaneous placement of a single implant in an ideal 3D position. Based on the CBCT images and intraoral scan, a surgical guide was fabricated based on 3D software. During surgery, this teeth-supported template can be placed intraorally, guiding sinus window opening preparation. This technique makes the sinus window opening procedure simple and predictable, reduces surgical time and the risk of complications, and allows the placement of the implant in the ideal 3D position.

In this paper, we extend the concept of fusibility to the module-theoretic setting by introducing fusible modules. Let $R$ be a ring with identity, $M$ a right $R$-module and $0\neq m\in M$. Then, $m$ is called fusible if it can be expressed as the sum of a torsion element and a torsion-free element in $M$. The module $M$ is said to be fusible if every non-zero element of $M$ is fusible. We investigate some properties of fusible modules. It is proved that the class of fusible modules is between the classes of torsion-free and nonsingular modules.

Published: September 2023

The Cf/C composite oxidation of polyacrylonitrile-based carbon fibers with a combined carbon matrix at 600°C up to a weight loss of 80 wt% has been investigated. The changes in the open porosity, specific surface area, apparent and true densities of the composite, as well as the ultimate strength and elastic modulus during three-point transverse bending tests have been analyzed. An analytical model for obtaining qualitative and semi-quantitative estimates of the change in integral pore size during oxidation of heterophase materials has been developed. The change in pore size is estimated through the evolution of open porosity P and materials specific surface area S. The model has been validated in the Cf/C composite oxidation study. The composite's mechanical properties dependences on the value of the integral pore size are obtained and analyzed. The structural parameter P/S characterizes the change in the interphase interaction during pores formation and development. It is established that the failure mechanism depends on the value of the parameter P/S and dynamically changes with the oxidation of Cf/C composite. The use of P/S parameter as a criterion for estimation and control of composite materials structural integrity in open systems is proposed.

In this investigation, we assessed the stability and physicochemical properties of copper oxide (CuO) nanoparticles dispersed in an Azadirachta indica oil-biodiesel blend (B20). CuO nanopartides were prepared at 75 ppm and the dispersants were added at the same ratio as the CuO nanoparticles. TRITON X, QPAN 80, and TWEEN 80 were used as dispersants. An ultrasonic bath sonicator was used to sonicate the nanoparticles and prepare the nanofuel. In addition, an ultraviolet photospectrometer was used in the stability analysis of the absorption and transmission. The stability analysis was carried out for a period of three weeks. The stability of the CuO nanoparticles increased in B20 when the dispersants were added compared to the base nanoparticles. However, higher absorption and lower permeability were observed in the QPAN-added nanofuels compared to the other samples. In addition, the stability of all of the nanofuel samples slightly decreased at the end of Week 3. For the B20 + CuO75 + Tw75 nanofuel, higher absorbance and lower transmittance values were obtained: 4.08 and 86.09% (Week 1), 4.06 and 88.03% (Week 2), and 4.04 and 92.03% (Week 3), respectively. Moreover, the physicochemical properties, such as the cetane number and heating value of the nanoparticle-added B20, were improved.

Tunnel excavation in geologically challenging areas can lead to slope instability and consequent landslides, which pose a serious threat to the integrity of the tunnel lining. To address this issue, a study was conducted to investigate the stability of the tunnel–landslide system using the finite-difference method (FDM) based on the Hanshankou tunnel of the Shaoguan–Xinfeng expressway in Guangdong province, China. A plane-strain model was used to examine the effect of various treatment measures on the system, and the strength reduction (incremental) method was employed to determine the range of initial slope safety factors applicable to different treatment measures, with the maximum shear strain increment serving as the criterion. The ‘anti-slip pile + anchor frame beam’ reinforcement system was found to be the most effective solution, reducing daily deformation by 60.1% after implementation. The results indicated that the pile–anchor reinforcement system can significantly mitigate landslide creep, and the corresponding treatment measures can be categorised based on the critical slope safety factor under different conditions.

This paper describes an analytical method for investigating the tunnel–pile interaction for new tunnels crossing the pile foundation of the Shenzhen Bay Bridge, with a case study using a cavity expansion-based model. The three-dimensional analytical model developed in this study evaluates the ground deformation and pile response induced by the construction of tunnels for the two Metro #13 lines and the Wanghai Road tunnel, and assesses the effectiveness of mitigation measures such as ground stabilisation and isolation walls. The study reveals significant vertical displacement and surface settlement caused by the Wanghai Road tunnel, and horizontal deformation and bending moments in specific pile foundations. The results show that reinforcement measures can effectively control formation deformation disturbance, and metro jet system isolation walls can limit horizontal and vertical displacements caused by excavation. To ensure the safe operation of the Shenzhen Bay Bridge, the study highlights the importance of comprehensively evaluating the safety of shield crossing schemes. The proposed analytical method could also serve as a pre-design tool and reference for optimising tunnel construction, providing valuable guidance for future reinforcement schemes. In general, this study provides significant insights into the tunnel–pile interaction, which will be useful for bridge and tunnel engineering design and construction.

Published: September 2023

Lack of coordination between driver and road geometry results in driver errors and crashes. Road geometric data constitute one of the primary requirements for safety analysis and improvement projects. A systematic literature review is presented here to identify existing methodologies for road geometric data extraction. Methodologies based on Global Positioning System (GPS), geographic information system (GIS) maps, AutoCAD digital maps, satellite imagery, inertial measurement unit, light detection and ranging (LiDAR) and vision technology were found employing manual, semi-automatic and automatic algorithms for extraction of horizontal alignment features of roads. A multi-criteria analysis in terms of device/software cost, data treatment cost and time acquisition was performed for the methodologies using an expert survey. Survey responses were analysed to rank the methodologies for minimum cost and time using an analytical hierarchical process. GPS- and GIS maps-based methodologies were the most economical, whereas the LiDAR-based methodology was the least economical. Overall, the findings provide valuable insights into components of existing methodologies. These findings could benefit practitioners, policymakers, enforcement authorities, vehicle manufacturers and researchers in the judicious selection of an appropriate methodology. An inventory of road geometric data could also be established to develop an intelligent transportation system by combining vehicle, road and driver in effective communication through information technologies.
İYİ YÖNETİM İLKELERİ ÇERÇEVESİNDE BELEDİYELERCE YÜRÜTÜLEN KAMU HİZMETLERİNE İLİŞKİN KAMU DENETÇİLİĞİ KURUMU (KDK) KARARLARI ÜZERİNE NİTEL BİR ARAŞTIRMA
Authors: ÖZKAYA Yakup
Published: September 2023

Belediyeler tarafından yerine getirilen kamu hizmetlerini Kamu Denetçiliği Kurumu (KDK) kararlarını referans alarak iyi yönetim ilkeleri çerçevesinde incelemeyi amaçlayan bu çalışma, üç bölüm olarak kurgulanmıştır. Belediyelerin Anayasa ve kanunlar ile belirlenen faaliyetlerinin kamusal hizmet olduğunu açıklayan birinci bölümden sonra dünyada ve Türkiye’de iyi yönetim ilkelerinin ne ifade ettiği açıklanmıştır. Son bölümde nitel analize yer verilmiştir. 2019-2023 yıllarını kapsayan çalışmada, KDK tarafından belediye hizmetleri ile ilgili verilen toplamda 362 karar Maxqda Analytics Pro 2022 isimli nitel veri analiz programı ile incelenmiştir. Vatandaşların, en fazla vergi/ödeme işlemleri, yapı kayıt/ruhsat, su, imar, yol ve altyapı gibi konularda KDK’ya başvuru yaptığı görülmüştür. Bu başvurulara karşı verilen kararlarda idarelerin genel olarak iyi yönetim ilkelerine uyma oranının uymama oranından yüksek olduğu ortaya çıkmıştır. Bununla birlikte idarelerin; “idarelerin makul sürede karar verme”, “hesap verilebilirlik”, “şeffaflık”, “kararın geciktirilmeksizin bildirilmesi”, “kararın gerekçeli olması” ve “kanunlara uygunluk” ilkelerine büyük oranda uyduğu saptanmıştır. İdarelerin en zayıf olduğu ilke ise “karara karşı başvuru yolları ve sürelerinin gösterilmesi” ilkesidir. Dürüstlük, nezaket, haklı beklentiye uygunluk gibi hukuki dayanağı olmayan iyi yönetim değerlerine uyulmadığı tespit edilmiştir.
