Authors: Çetingöz Mustafa , Tez Taşkın , Akı Ozan , Akal Dinçer , Umut İlhan
Published: December 2024

Turkey is more advantageous than many countries in terms of solar radiation intensity and sunbathing time due to its location. However, costs such as land, transportation, security, etc. required for the establishment of solar power plants increase the total cost. For this reason, the use of solar panels as a fencing system in agricultural areas offers some advantages. The vertical or angled positioning of the solar panels according to the terrain conditions has a significant effect on both the investment cost and the amount of electricity generated. In this study, the technical and economic analysis of the solar panels to be used as a fence on the border of the Faculty of Engineering campus of Trakya University with 90° and 32° angles is investigated using the PV sol software. The investment cost of the fencing application was determined to be 3.726.000TL depending on the installed power of the designed solar energy system, the characteristics of the system components, and the location. Analyzing the simulation results, the payback period is 7 years if the solar panels are positioned at 90° and 6.2 years if the tilt angle of the solar panels is 32°. It can therefore be seen that the tilt angle of the solar panels in the location where they are installed in agricultural fencing applications is effective in terms of the amount of energy produced and the payback period.
ENHANCING DEPTH DATA IN TIME-OF-FLIGHT (TOF) CAMERAS: A COMPREHENSIVE COMPARATIVE STUDY OF FILTERING TECHNIQUES
Authors: Lyubenov Alexandar , Ivanov Stefan
Published: December 2024

Time-of-Flight (ToF) cameras have become critical instruments in applications demanding real-time 3D depth sensing, such as robotics, augmented reality, and industrial inspection. However, the accuracy of ToF cameras, including models such as the CamBoard pico flexx, is frequently compromised by depth inaccuracies arising from various noise sources. To mitigate these issues, this study investigates the performance of five established filtering techniques: the Wiener filter, Non-Local Means (NLM) filter, Gaussian filter, Bilateral filter, and Median filter. These methods were applied to depth data captured by the CamBoard pico flexx. The paper presents experimental results demonstrating the effectiveness of each filter in improving the quality of depth maps. Prior studies are referenced to provide additional context for the filtering methodologies employed in ToF camera systems.

Authors: Adli Hanisah Izati , Mohamed Noor An’amt , Abdullah Nor Hakimin , Ali Arlina , Ibrahim Norfadhilah
Published: December 2024

The effect of the silver complex on graphene oxide and its antibacterial studies was reported in this work. Graphene oxide (GO) has a high specific surface area and is well-known for being an ideal substrate material for growing silver nanoparticles. The simplified Hummer's method was chosen to prepare GO and Silver nanoparticles (AgNPs), which have been decorated on the surface of GO during the reduction of silver complex solution [Ag(NH3)2OH] in GO aqueous solution. The obtained nanocomposite was analyzed by using Ultraviolet-visible spectrophotometry (UV-Vis) and X-ray diffraction (XRD). The antibacterial performance against Gram-negative bacteria (Escherichia coli) and Gram-positive bacteria (B. subtilis) was investigated using the disk agar diffusion method. The diameter of the inhibition zone indicates the effectiveness of GOAlgAg in preventing these bacteria from growing while displaying the nanocomposite as a promising material for antibacterial-related applications. The best antibacterial properties were found in a sample of 5.0:2.5ml GOAlgAg, which shows the highest inhibition zone, 0.85cm toward Escherichia coli and 1.03cm toward B. subtilis.

Araştırmada, okul öncesi eğitim alan ve almayan çocukların depremle ilgili bilgilerinin kıyaslanması amaçlanmıştır. Araştırmada, nitel araştırma yöntemlerinden olgubilim (fenomenoloji) deseni kullanılmıştır. Araştırmanın çalışma grubunu, amaçlı örnekleme yöntemiyle belirlenen okul öncesi eğitim alan (n=12) ve almayan (n=12) beş-altı yaşlarındaki çocuklar oluşturmaktadır. Araştırmanın verileri “Genel Bilgi Formu” ve yarı yapılandırılmış “Görüşme Formu” kullanılarak toplanmıştır. Veriler, betimsel içerik analiz yöntemiyle analiz edilmiştir. Araştırma sonuçları, okul öncesi eğitim alan çocukların depremle ilgili bilgilerinde farklılıklar olduğunu göstermektedir. Okul öncesi eğitim almış çocukların, depremin nedenine coğrafi açıklamalar getirdikleri; depremden önce hazırlık konusunda bilinçli ve çeşitli hazırlıklar yapmaya daha eğilimli oldukları; deprem anında "Çök, Kapan, Tutun" ve "Yaşam Üçgeni" gibi önlemleri ifade ettikleri görülmüştür. Ne yazık ki her iki grupta yer alan çocuklar, depremin nedenini bilmediklerini, deprem öncesinde herhangi bir hazırlık yapmadıklarını ve deprem anında dışarı çıkmanın ve kaçmanın bir korunma yöntemi olduğunu ifade etmişlerdir. Hem okul öncesi eğitim alan hem de almayan çocuklar, depremden önce elbise-eşya hazırlamayı, deprem olmayan yerlere gitmeyi; insanların deprem anında korku/üzüntü hissettiklerini ve telaşlı olduklarını; deprem sonrasında insanların güvenli bir yerde bulunacağını; çocukların ise depremden sonra yemek yiyeceğini ve parkta oynayacağını belirtmişlerdir.

Authors:   Project Manager, Global Welfare Academy of  Research Institution, Dhaka, Bangladesh, Khan Armanul Islam
Published: December 2024

Predictive maintenance (PdM) has emerged as a key strategy for enhancing operational efficiency in manufacturing by leveraging data analytics to forecast equipment failures and optimize maintenance activities. This paper systematically reviews the current state of predictive maintenance in manufacturing, with a particular focus on the integration of data-driven techniques, including machine learning and Internet of Things (IoT) technologies, for improved maintenance management. The review highlights the effectiveness of various predictive models, such as random forests, support vector machines, and artificial neural networks, in predicting machine failures and reducing downtime. It also explores the role of IoT sensors in real-time monitoring of equipment and the challenges associated with data quality, sensor reliability, and the integration of legacy systems. The paper examines the cost-benefit considerations of adopting predictive maintenance systems, revealing that while the initial investment can be significant, the long-term savings from reduced unplanned downtime, extended equipment lifespan, and optimized maintenance operations often justify the expenditure. Additionally, it discusses the barriers to PdM adoption, including the need for skilled labor, organizational resistance to change, and challenges related to data management. Looking ahead, the review identifies key emerging technologies, such as artificial intelligence (AI), digital twins, and edge computing, as critical enablers for the future of predictive maintenance. These technologies are expected to enhance the accuracy and real-time capabilities of predictive models, further driving efficiency in manufacturing operations. The paper concludes that while challenges remain, the continued advancement of predictive maintenance, underpinned by data analytics, will play a pivotal role in driving operational excellence and competitiveness within the manufacturing sector.

Former de futures personnes enseignantes
Authors: Nadeau Sandy
Published: December 2024

L’engagement parental est central pour l’accompagnement scolaire de l’enfant. Il apparait ainsi pertinent de le soutenir afin qu’il puisse collaborer avec l’école. Or, plusieurs études reconnaissent que les parents de milieux plus défavorisés ont tendance à rencontrer plus de difficultés à s’engager dans l’accompagnement de leur enfant, ce qui représente un obstacle à l’équité pour favoriser la réussite de tous les élèves.

Il ressort que les personnes enseignantes se sentent démunies et peu outillées pour soutenir l’engagement de parents issus de milieux défavorisés (Lozancic et al., 2019). Pour l’équité et l’inclusion de ces élèves et de leur famille, une plus grande compréhension des raisons sous-jacentes au faible engagement de ces parents et des défis qu’ils rencontrent apparait incontournable.

Dans le cadre de la formation en enseignement au préscolaire et au primaire, une initiative est ainsi mise en place dans le but que les personnes enseignantes portent un regard sur les caractéristiques de cette relation bidirectionnelle entre la personne enseignante et le parent, notamment au regard des réalités dans les milieux défavorisés. Dans l’idée de sensibiliser les acteurs qui collaborent avec des parents économiquement et socialement vulnérables, des leviers sont identifiés.
Weaving a Better Future
Authors: Duquette Patrick , Simon Joseph
Published: December 2024

Within our educational system, we have often heard equity referred to as the
appropriate distribution of resources such as assistive technology, or extra time on
exams, with academic success as the goal. We appreciate this view of equity, but we
would like to expand it. What if, instead of seeing equity only as the provision of
material resources to students, we also saw it as the provision of social and
emotional resources ? Furthermore, what if instead of only having academic success
as the end goal of education, we also aimed for students’ well-being ? Moreover, we
would also like to argue that by doing this we would also be able to enhance their
chances of success in life beyond academics. Allow us to explain.

Les antécédents de la performance adaptative : où en est-on après Park et Park (2019) ?
Authors: Myre Francis , Longato Sabrina , Ouellette Samuel , Boudrias Jean-Sébastien
Published: December 2024

Avec la nature du travail qui change constamment, la capacité des employés à acquérir des nouvelles compétences devient un bénéfice de plus en plus recherché par les organisations. La performance adaptative (PA) permet de répondre à cette réalité en intégrant la notion d’adaptation en contexte de travail au concept de performance. Pourtant, malgré un bon nombre d’études menées dans les dernières années, les données empiriques portant sur les antécédents de la PA (p.ex. caractéristiques individuelles, de groupe, de l’emploi et de l’organisation) sont encore limitées et parfois contradictoires. De plus, la recherche a évolué vers plusieurs méthodes et perspectives menant à des séparations dans la base de connaissances sur la PA. Le but de la présente étude est de mettre à jour la plus récente revue de littérature sur les prédicteurs (antécédents) de la PA. Elle vise aussi à recadrer les connaissances actuelles sur les prédicteurs de la PA autour des liens démontrés empiriquement. Cette revue est majoritairement basée sur les travaux récents de Park et Park (2019), en plus d’ajouter des articles publiés entre 2016 et mars 2023. En somme, 40 articles empiriques ont été retenus et supportent un total de 38 prédicteurs de la PA. L’ensemble des liens empiriques sont présentés, catégorisés et affichés sous forme de tableau pour faciliter la comparaison, puis les tendances dans la littérature ainsi que des pistes de recherches futures sont discutées.
Rejuvenating aged osteoprogenitors for bone repair
Authors: Reeves Joshua , Tournier Pierre , Becquart Pierre , Carton Robert , Tang Yin , Vigilante Alessandra , Fang Dong , Habib Shukry J
Published: December 2024

Aging is marked by a decline in tissue regeneration, posing significant challenges to an increasingly older population. Here, we investigate age-related impairments in calvarial bone healing and introduce a novel two-part rejuvenation strategy to restore youthful repair. We demonstrate that aging negatively impacts the calvarial bone structure and its osteogenic tissues, diminishing osteoprogenitor number and function and severely impairing bone formation. Notably, increasing osteogenic cell numbers locally fails to rescue repair in aged mice, identifying the presence of intrinsic cellular deficits. Our strategy combines Wnt-mediated osteoprogenitor expansion with intermittent fasting, which leads to a striking restoration of youthful levels of bone healing. We find that intermittent fasting improves osteoprogenitor function, benefits that can be recapitulated by modulating NAD+-dependent pathways or the gut microbiota, underscoring the multifaceted nature of this intervention. Mechanistically, we identify mitochondrial dysfunction as a key component in age-related decline in osteoprogenitor function and show that both cyclical nutrient deprivation and Nicotinamide mononucleotide rejuvenate mitochondrial health, enhancing osteogenesis. These findings offer a promising therapeutic avenue for restoring youthful bone repair in aged individuals, with potential implications for rejuvenating other tissues.
Antimicrobial activity of iron-depriving pyoverdines against human opportunistic pathogens
Authors: Vollenweider Vera , Rehm Karoline , Chepkirui Clara , Pérez-Berlanga Manuela , Polymenidou Magdalini , Piel Jörn , Bigler Laurent , Kümmerli Rolf
Published: December 2024

The global rise of antibiotic resistance calls for new drugs against bacterial pathogens. A common approach is to search for natural compounds deployed by microbes to inhibit competitors. Here, we show that the iron-chelating pyoverdines, siderophores produced by environmental Pseudomonas spp., have strong antibacterial properties by inducing iron starvation and growth arrest in pathogens. A screen of 320 natural Pseudomonas isolates used against 12 human pathogens uncovered several pyoverdines with particularly high antibacterial properties and distinct chemical characteristics. The most potent pyoverdine effectively reduced growth of the pathogens Acinetobacter baumannii, Klebsiella pneumoniae, and Staphylococcus aureus in a concentration- and iron-dependent manner. Pyoverdine increased survival of infected Galleria mellonella host larvae and showed low toxicity for the host, mammalian cell lines, and erythrocytes. Furthermore, experimental evolution of pathogens combined with whole-genome sequencing revealed limited resistance evolution compared to an antibiotic. Thus, pyoverdines from environmental strains have the potential to become a new class of sustainable antibacterials against specific human pathogens.

Objective

To characterize the epidemiological characteristics of malignancy in Chinese patients with rheumatoid arthritis (RA) versus American patients and investigate their associated factors.

Methods

Data were collected from a real-world Chinese RA population and American patients with RA from the National Health and Nutritional Examination Survey. The prevalence and subtypes of malignancy and their potential associated factors were investigated in both populations.

Results

A total of 2,073 Chinese and 2,928 American patients with RA were included. There was a lower prevalence of malignancy in Chinese than in their American counterparts before (5.7% vs. 17.1%) and after matching (6.2% vs. 12.6%, both P < 0.001). Gender discrepancies in malignancy prevalence were observed, with a male predilection for RA with malignancy in China (8.2% vs. 5.5%), while it was the opposite in American patients (10.1% vs. 13.5%, both P < 0.05). The top type of malignancy among male patients with RA was lung cancer in Chinese (2.29%), but non-melanoma skin cancer (3.43%) in American; while among female patients was breast cancer both in Chinese (1.72%) and American (3.43%). Multivariate logistic regression analyses showed that older age (odds ratio (OR) = 1.050) and positive anti-cyclic citrullinated peptide antibody (OR = 2.752) were independently associated with malignancy in Chinese patients with RA, while female (OR = 1.395), older age (OR = 1.033), active smoking (OR = 1.580) and cardiovascular diseases (OR = 1.523) in American patients.

Conclusion

The prevalence, subtypes and risk factors of malignancy were substantially different in Chinese patients with RA and their American counterparts, which implied the importance of individualized malignancy screening strategies for patients with RA.

Black pepper holds significant importance as a spice crop in Kerala, a state often referred to as the "Land of Spices" for its substantial contribution to India's economy through exports. Phytophthora foot rot poses a significant challenge in nurseries across the black pepper-growing regions of Kerala, leading to substantial economic losses for farmers. A study was undertaken to develop and evaluate a tablet formulation of Plant Growth Promoting Microbes (PGPM) and other biocontrol agents for promoting growth and managing foot rot disease in black pepper (Piper nigrum L.). The findings revealed that the PGPM tablet formulation, along with the liquid formulation of Trichoderma (KAU), emerged as the most effective treatments for suppressing foot rot. Biometric analysis showed that plants treated with the PGPM tablet (Bacillus cereus., Trichoderma spp.) formulation recorded the greatest plant height, number of nodes, and leaves, performing on par with the talc-based PGPM formulation. Soil microbial analysis, conducted before and after treatment using serial dilution and plating techniques, indicated that the PGPM tablet consistently supported the highest counts of viable fungi, bacteria, and actinomycetes in the soil. Thus, the tablet formulation of PGPM emerged as the most effective treatment for promoting growth and managing Phytophthora disease in black pepper, showcasing its potential as a promising solution for sustainable crop health and productivity.

Detection of molecular markers with parental polymorphism is a pre-requisite for QTL mapping and further identification of genomic regions. PCR based InDel markers tend to have a greater degree to show polymorphism among the parental genotypes for any specific cross. Polymorphic studies were carried out between the two parents Swarna (Cultivated rice variety) and Oryza rufipogon IC309814 (Wild rice accession) using 192 randomly selected InDel markers and 40 gene specific markers for Iron and Zinc covering the entire 12 chromosomes. Results revealed that InDel markers were polymorphic between both the parents and highest percentage of polymorphism observed on chromosome 10 (75%) followed by chromosome 5 (60%) and chromosome 9 (55.6%) and lowest polymorphism percentage was shown in chromosome 3 (8.3%) with an overall 22.4 % polymorphism percentage among all the markers used in this study. Detected polymorphic (SSR) markers were for genotyping the mapping population derived from the cross between Swarna cultivar and Oryza rufipogon to map Quantitative Trait Loci (QTLs) associated with yield and grain quality traits.

Ice accretion on external aircraft surfaces due to the impact of supercooled water droplets can negatively affect the aerodynamic performance and reduce the operational capability and, therefore, must be prevented. Icephobic coatings capable of reducing the adhesion strength of ice to a surface represent a promising technology to support thermal or mechanical ice protection systems. Icephobicity is similar to hydrophobicity in several aspects and superhydrophobic surfaces embody a straightforward solution to the ice adhesion problem. Short/ultrashort pulsed laser surface treatments are proposed as a viable technology to generate superhydrophobic properties on metallic surfaces. However, it has not yet been verified whether such surfaces are generally icephobic under representative icing conditions. This study investigates the ice adhesion strength on Ti6Al4V, an alloy commonly used for aerospace components, textured by means of direct laser writing, direct laser interference patterning, and laser‐induced periodic surface structures laser sources with pulse durations ranging from nano‐ to femtosecond regimes. A clear relation between the spatial period, the surface microstructure depth, and the ice adhesion strength under different icing conditions is investigated. From these observations, a set of design rules can be defined for superhydrophobic surfaces that are icephobic, too.

Based on a recent droplet microfluidic device for target molecules' extraction, purification, and redispersion, here an original fluidic control system is proposed to improve the device versatility and usability. This approach relies on the coupling of functionalized magnetic particles handling by integrated soft magnets and a passive droplet splitting control at a channel junction. To reach the high standards required for bioassays' implementation, this device integrates a pressure‐driven variable volume component, acting as a fluidic capacitor, which allows a passive and controlled self‐triggered droplet fingering in a dead‐end channel. The working principle is described, and the modeling of the induced fingering phenomenon by an electric analogy is presented. Then, the achieved finger length is characterized as a function of geometrical and material properties of the fluidic capacitor. The complete device configuration guarantees extraction and purification efficiencies higher than 97% and 95%, respectively, showing high‐throughput particles handling between droplets with a passive droplet splitting control. Finally, this technology is successfully applied to gene expression study for cancer diagnosis by performing magnetic particle–based messenger RNA (mRNA) extraction followed by reverse transcription (RT) and quantitative polymerase chain reaction (RT‐qPCR) analysis.

Chemical/biological sensing by means of luminescence still requires improvement of signal contrast and depth of sample imaging. Though there is a considerable number of emissive molecular and quantum dot probes, most of them absorb in the UV–vis range and emit in the visible and exhibit emission lifetime in the nanoscale. Optical bioimaging in the near infrared window based on these dyes offers reduced light scattering, lower competitive absorption, and reduced background autofluorescence, but it requires a high‐power pulsed laser. An approach to lengthening the emission lifetime of common fluorophores/probes is presented. It consists of coupling them to lanthanide‐based upconversion nanoparticles (UCNPs) via an easy, jigsaw‐like strategy. As a proof of concept, nanohybrids comprising UCNPs attached to fluorescein (a well‐known pH sensor) are prepared by connecting the key pieces through ionic interactions, i.e., without using any other reagents. Fluorescence imaging of the nanohybrids clearly shows the co‐occurrence of the UCNP and the chemical probe and as a consequence the long‐lived fluorescence of the probe due to resonance energy transfer from the UCNP. This strategy opens up endless possibilities to prepare new nanohybrids by selecting the key jigsaw pieces to exploit the color emission of common probes.

Published: February 2020

Second‐harmonic generation (SHG) has recently been explored in plasmonic metamaterials, but real‐time tunability of the nonlinear process still remains a challenge and has not been reported. Here, an ultrathin spoof surface plasmon polariton (SSPP) waveguide loaded with varactor diodes is proposed to achieve high conversion efficiencies of SHGs in both forward and backward phase‐matching conditions in the same frequency band. The dispersion behaviors of SSPPs can be manipulated by adjusting the capacitance of the varactor diodes loaded on the unit structure, allowing forward and backward phase‐matching for both fundamental and second‐harmonic waves. Experiments are demonstrated in the microwave frequency to observe the dynamic controls of the forward/backward SHGs in a single SSPP platform, showing good agreement with theoretical predictions. It is expected that the reconfigurable SHGs may find many applications in nonlinear plasmonic metamaterials, wireless communication systems, and microwave integrated circuits.

Development of next‐generation thermal interface materials (TIMs) with high thermal conductivity is important for thermal management and packaging of electronic devices. The synthesis and thermal conductivity measurements of noncuring thermal paste, i.e., grease, based on mineral oil with a mixture of graphene and few‐layer graphene flakes as the fillers, is reported. The graphene thermal paste exhibits a distinctive thermal percolation threshold with the thermal conductivity revealing a sublinear dependence on the filler loading. This behavior contrasts with the thermal conductivity of curing graphene TIMs, based on epoxy, where superlinear dependence on the filler loading is observed. The performance of the thermal paste is benchmarked against top‐of‐the‐line commercial thermal pastes. The obtained results show that noncuring graphene TIMs outperforms the best commercial pastes in terms of thermal conductivity, at substantially lower filler concentration of φ = 27 vol%. The obtained results shed light on thermal percolation mechanism in noncuring polymeric matrices laden with quasi‐two‐dimensional fillers. Considering recent progress in graphene production via liquid phase exfoliation and oxide reduction, the results open a pathway for large‐scale industrial application of graphene in thermal management of electronics.
