Full textAbstract:
Glass ionomer cements (GICs) have been available for use by clinicians for almost 50 years. Their beneficial properties, such as adhesion to tooth substance, have long been recognized, but early materials suffered from brittleness, lack of translucency, poor wear resistance and solubility in oral fluids. Hence, over the years, new variants have been developed with a view to overcoming these difficulties. If the latest materials were found to be clinically successful in loadbearing situations in posterior teeth, they could hold advantages because of their easier placement than resin composite materials and possibly be more cost-effective. It is therefore the purpose of this article to review recent research into the performance of the laboratory and clinical performance of high viscous GICs and the so-called glass hybrid materials that have developed from the conventional GICs. CPD/Clinical Relevance: Glass ionomer materials, which, unlike resin composite restorations do not need a separate bonding agent, may hold technique advantages during restoration placement.

Full textAbstract:
Glass ionomer cements (GICs), restorative materials with commercial availability spanning over five decades, are widely applied due to their advantages (including bio-compatibility, fluoride release, or excellent bonding properties). However, GICs have shortcomings. Among the disadvantages limiting the application of GICs, the poor mechanical properties are the most significant. In order to enhance the mechanical or antimicrobial properties of these materials, the addition of nanomaterials represents a viable approach. The present paper aims to review the literature on the application of different types of nanomaterials for the enhancement of GICs’ mechanical and antimicrobial properties, which could lead to several clinical benefits, including better physical properties and the prevention of tooth decay. After applying the described methodology, representative articles published in the time period 2011-present were selected and included in the final review, covering the modification of GICs with metallic nanoparticles (Cu, Ag), metallic and metalloid oxide nanoparticles (TiO2, ZnO, MgO, Al2O3, ZrO2, SiO2), apatitic nanomaterials, and other nanomaterials or multi-component nanocomposites.

Purpose. Despite the advantages of glass ionomer cement (GIC) including chemical bonding to the tooth structure and fluoride release, its low-grade mechanical properties make it a topic for research. Accordingly, this study was conducted to assess the ability of sesame oil as a natural bioactive additive to reinforce conventional glass ionomer cement. Materials and Methods. Sesame oil was blended into the liquid component of the cement in ratios of 3 and 5 ( v / v % ). One control and two experimental groups were enrolled in the study; I: unmodified GIC (control), II: 3 ( v / v % ) sesame oil-modified GICs, and III: 5( v / v % ) sesame oil-modified GICs. Compressive strength, shear bond strength, diametral tensile strength, surface microhardness, surface roughness, and color stability were the parameters assessed. A representative specimen of each group was analyzed for its chemical structure by Fourier transformation infrared spectroscopy. One-way ANOVA followed by Tukey test was used to analyze the collected data of all evaluated parameters except the color stability results, which were analyzed by Student t-test at p < 0.05 . Results. Three and 5 ( v / v % ) sesame oil-modified GICs exhibited significant increase in their compressive strength, shear bond strength, diametral strength, and surface microhardness. Concurrently, there was a significant decrease in surface roughness ( p < 0.05 ) in both formulations of the modified cement. Both 3 and 5 ( v / v % ) sesame oil-modified GICs showed a clinically acceptable color change. Conclusions. Sesame oil seems to be a promising natural bioactive product for reinforcement of conventional GIC with a clinically agreeable esthetic.

<strong>Abstract</strong> Modern dentistry does not stand still, it is constantly developing. New filling materials are being created, but glass ionomer cements(GIC) do not lose their popularity. Among dentists, they are valued for their positive properties. GICs have high adhesion, low toxicity, good strength, and in addition, when they are used, a cariesostatic effect is observed [1]. Every year, interest in this type of materials only grows. They are used for filling both temporary and permanent teeth, for fixing crowns and other structures, for restoring defects, etc. [2; 3]. You can see a wide variety of GICs on the dental market, which allows dentist to solve many dental problems. Each doctor can find suitable material for his work, based on his preferences and the patient's financial capabilities [4]. Scientists do not stop in their attempts to improve the quality of GICs, so new varieties of glass ionomer cements are constantly appearing. <strong>Аннотация</strong> Современная стоматология не стоит на месте, она постоянно развивается. Создаются новые пломбировочные материалы, однако не теряют своей популярности и стеклоиономерные цементы(СИЦ). Среди стоматологов они ценятся за их некоторые положительные свойства. СИЦ обладают высокой адгезией, малой токсичностью, хорошей прочностью, а кроме того, при их применении наблюдается кариесостатический эффект [1]. С каждым годом интерес к данному виду материалов только растет. Они используются при пломбировании как временных, так и постоянных зубов, для фиксации коронок и других конструкций, для реставрации дефектов и т.д. [2; 3]. На стоматологическом рынке можно увидеть большое разнообразие СИЦ, что позволяет стоматологу решать множество стоматологических задач. Каждый врач может найти для себя подходящий материал, основываясь на своих предпочтениях и материальных возможностях пациента [4]. Ученые не останавливаются в своих попытках усовершенствовать качества СИЦ, поэтому постоянно появляются новые разновидности стеклоиономерных цементов.

ABSTRACT Glass-ionomer cements (GICs) are mainstream restorative materials that are bioactive and have a wide range of uses, such as lining, bonding, sealing, luting or restoring a tooth. Although the major characteristics of GICs for the wider applications in dentistry are adhesion to tooth structure, fluoride releasing capacity and tooth-colored restorations, the sensitivity to moisture, inherent opacity, long-term wear and strength are not as adequate as desired. They have undergone remarkable changes in their composition, such as the addition of metallic ions or resin components to their composition, which contributed to improve their physical properties and diversified their use as a restorative material of great clinical applicability. The lightcured polymer reinforced materials appear to have substantial benefits, while retaining the advantages of fluoride release and adhesion. Further research should be directed towards improving the properties, such as strength and esthetics without altering its inherent qualities, such as adhesion and fluoride releasing capabilities.

The Glass Ionomers Cements (GICs) are materials widely used in dentistry, have advantages such as fluoride release and chemical adhesion to the dental substrate. They are recommended as a restorative material, luting agent in prosthetic dentistry and also in medicine. However, there is need for developing new bone cements as an alternative or replacement to the current polymethylmethacrylate cements, therefore, the objective of this research was to develop an experimental GIC and characterization regarding morphology, chemical composition and crystallinity. This composite was characterized by X-ray diffraction (XRD), Infrared Spectroscopy Fourier Transform (FTIR) and optical microscopy (OM). For comparative study, was used the GIC Vidrion R (SS White) in the control group. These cements are presented in semi-crystalline diffraction patterns, the FTIR spectra observed characteristic bands of these materials and microstructural study of the cements showed homogeneous distribution of filler in the polymer matrix, corroborating with the literature.

Full textAbstract:
The placement of root filling materials aims to prevent the occurrence of post-treatment apical periodontitis following completion of endodontic treatment. Materials should possess properties that will not permit bacterial invasion and infection, namely excellent sealing ability and/or antibacterial properties. In root-end filling procedures or repair of root perforations, the root filling materials are placed in a particularly challenging clinical environment, as they interface with a relatively large area with the periradicular tissues. The biological properties of these materials are therefore of significant importance. The current review discusses the most widely used materials for endodontic surgery (i.e., root-end filling and perforation repair), with particular focus on their biological characteristics, namely antibacterial properties and interactions with host tissue cells, together with clinical studies. Properties of amalgam, glass ionomer cements (GICs), resin systems, zinc oxide eugenol-based cements and hydraulic calcium silicate cements (HCSCs), together with representative and well-researched commercial materials in the context of their use in endodontic surgery are presented. While the use of HCSCs seems to offer several biological advantages, together with addressing issues with the initial formulation in the most recent versions, materials with different chemical compositions, such as zinc oxide eugenol-based cements, are still in use and appear to provide similar clinical success rates to HCSCs. Thus, the significance of the currently available materials on clinical outcomes remains unclear.

Resúmen: El norte de Tierra del Fuego (Argentina) cuenta con una interesante historia geológica y geomorfológica pero también cultural; se trata de un espacio geográfico que ha sido habitado por grupos de cazadores-recolectores pedestres desde al menos 6000 años. Desde la segunda mitad del siglo XIX, la instalación del hombre blanco generó también evidencias aún hoy visibles en el paisaje, además de los numerosos documentos escritos generados por diversos exploradores. Debido a su relevante geodiversidad con contenido cultural, este entorno resulta un escenario susceptible de uso turístico-recreativo. Para ello, se propone el concepto de georrecurso cultural (GC), es decir, aquel elemento de origen geológico y/o geomorfológico que posee algún tipo de registro arqueológico y/o histórico. En este marco, la presente contribución tiene por objetivos presentar una metodología para el análisis de GC para el uso turístico y mostrar su aplicación en el norte de Tierra del Fuego. La propuesta metodológica implica distintas etapas, con trabajo de campo y de gabinete. A partir de la revisión bibliográfica, se diseñaron dos instrumentos de recolección de datos: una ficha descriptiva y una matriz paramétrica basada en tres ejes de análisis: geológico-geomorfológico, arqueológico-histórico y turístico-recreativo. La aplicación de ambos instrumentos permitió jerarquizar los GC y aprovechar su potencialidad didáctica mediante la divulgación de diversas disciplinas científicas. Abstract: ASSESSMENT OF CULTURAL GEORESOURCES FOR TOURIST USE. APPLYING A METHODOLOGY IN NORTHERN TIERRA DEL FUEGO (ARGENTINA). The North of Tierra del Fuego (Argentina) has an interesting geological and geomorphological history but also cultural; it is a geographical space that has been inhabited by groups of pedestrian hunter-gatherers for at least 6,000 years. Since the second half of the 19th century, the settlement of the white man also generated evidence that is still visible today in the landscape, in addition to the numerous written documents left by various explorers. Due to its relevant geodiversity and cultural content, this environment is a susceptible scenario to tourist-recreational use. In this sense, the concept of cultural georesource (GC) is proposed as an element of geological and/or geomorphological origin that has some type of archaeological and/or historical record associated. In this framework, the present contribution aims to present a methodology for the analysis of GC for tourist use as well as to show its application in Northern Tierra del Fuego. The methodological proposal involves different stages through field and office work. Based on bibliographic review, two data collection instruments were designed: a descriptive chart and a parametric matrix based on three axes of analysis which are geological-geomorphological, archaeological-historical, and tourist-recreational. The application of both instruments allowed us to rank the GC taking advantage of their didactic potential through the dissemination of various scientific disciplines.

Full textAbstract:
Spatial and spectral information are essential sources of information in remote sensing applications, and the fusion of panchromatic and multispectral images effectively combines the advantages of both. Due to the existence of two main classes of fusion methods—component substitution (CS) and multi-resolution analysis (MRA), which have different advantages—mixed approaches are possible. This paper proposes a fusion algorithm that combines the advantages of generalized intensity–hue–saturation (GIHS) and non-subsampled shearlet transform (NSST) with principal component analysis (PCA) technology to extract more spatial information. Therefore, compared with the traditional algorithms, the algorithm in this paper uses PCA transformation to obtain spatial structure components from PAN and MS, which can effectively inject spatial information while maintaining spectral information with high fidelity. First, PCA is applied to each band of low-resolution multispectral (MS) images and panchromatic (PAN) images to obtain the first principal component and to calculate the intensity of MS. Then, the PAN image is fused with the first principal component using NSST, and the fused image is used to replace the original intensity component. Finally, a fused image is obtained using the GIHS algorithm. Using the urban, plants and water, farmland, and desert images from GeoEye-1, WorldView-4, GaoFen-7 (GF-7), and Gaofen Multi-Mode (GFDM) as experimental data, this fusion method was tested using the evaluation mode with references and the evaluation mode without references and was compared with five other classic fusion algorithms. The results showed that the algorithms in this paper had better fusion performances in both spectral preservation and spatial information incorporation.

Full textAbstract:
Glass ionomer cements (GICs) are dental materials that were invented by Wilson & Kent in 1972. They can chemically bond to enamel and dentin and can exhibit anti-cariogenic activity that allows the release and uptake of fluoride ions. They also possess the ability to render color. The setting reaction of GICs is a neutralization reaction that results in the formation of polycarboxylate salts. The most important GIC modification process involves the addition of resin components, resulting in the development of resin-modified glass ionomer cements (RMGICs), which contain self-and photo-curing systems. Modification of conventional GICs and RMGICs can be achieved by the incorporation of nano-sized fillers into the materials. This helps reduce the size of RMGICs. Conventional GICs and RMGICs can also be modified by introducing nano-sized bioceramics to the glass powder. It has been previously reported that the incorporation of nano-sized particles helps improve the mechanical properties of conventional GICs. Conversely, the commercially available nano-filled RMGICs do not hold any significant advantage over conventional RMGICs as far as the mechanical and adhesive properties are concerned. Glass carbomer is a novel glass ionomer material, and the bioactivity of which is better than the bioactivity of the conventional GICs. However, it is more brittle and less strong than the modern conventional GICs. Additionally, clinical techniques that can be used to transfer external energy on the surface of a GIC have also been used for modification. These techniques can be used to reduce the duration of the initial setting stage and improve the rate of the setting reactions, resulting in faster development of the mechanical properties. Premature failure of the restorations can be avoided under these conditions. The lack of long-term clinical studies limits the use of nano-modified glass ionomers and glass carbomers in daily clinical practice. More randomized clinical trials are required to justify the use of these modern modified materials.

SummaryThe object of this retrospective clinical study was to evaluate the efficacy of arthroscopic lavage and debridement, followed by intra-articular implantation of resorbable gentamicin-impregnated collagen sponges (GICS) for treatment of chronic (≥ seven days) septic arthritis in cattle. Fourteen cattle suffering from chronic septic monarthritis refractory to previous treatment were included in this study. Age ranged from one month to 7 years (mean = 34 months) and bodyweight from 58 to 640 kg (mean = 422 kg). The degree of lameness and characteristics of synovial fluid were evaluated before and at days #10 and 20 after the initial operation. The standard surgical procedure consisted of arthroscopic “through-and-through” lavage of the affected joint with a physiological Ringer’s solution, partial synovectomy, and curettage of the articular cartilage when considered necessary, followed by the intra-articular administration of GICS. The aftercare included administration of procaine penicillin, phenylbutazone, and stall confinement. The progress of the cases was monitored at three to 24 months after the initial operation.The tarsocrural joint was affected in six cases, the antebrachiocarpal joint in five and the metacarpophalangeal joint in three cases. The degree of lameness, total nucleated cell count and total protein of synovial fluid significantly (P <.05) decreased within 10 days after the operation. Treatment was successful in 12 of 14 animals (86%). It was therefore concluded that the implantation of GICS after routine “throughand- through” lavage is a valuable alternative technique for the treatment of chronic septic arthritis in cattle. A subsequent second operation for implant removal was not necessary, as GICS are fully absorbable. The tarsocrural joint is associated with the least favourable prognosis of the joints treated in this study.The efficacy of arthroscopic “through-and-through” lavage and debridement, followed by intra-articular implantation of absorbable gentamicin-impreg-nated collagen sponges (GICS) for treatment of chronic (≥ seven days) septic arthritis in cattle was evaluated. Treatment was successful in 12 of 14 cattle (86%). This suggests that the described technique is a valuable alternative to established treatment regimens for prolonged intra-articular administration of gentamicin. When compared to gentamicin-impregnated polymethylmethacrylate beads, GICS have the advantage that a second operation for implant removal is not necessary.

Geosites represent important elements of geoheritage for promoting geotourism sustainable practices aimed at education and conservation. The Santa Elena Peninsula Geopark Project has several locations with geological, cultural and historical richness and the potential for geosites and tourist development. However, these places lack infrastructures that improves tourist reception and local geoeducation. In this study, Geotourism Interpretation Centres (GICs) were designed using sustainable and architectural criteria to improve geoeducation and geotourism in geosites of the Santa Elena Peninsula Geopark Project. The work included two stages: (i) selection of the geosites and (ii) design of the GICs. Four geosites were selected for the design: Barrio Ingles Ancon Parish, Manglaralto’s Coastal Aquifer, San Vicente Hot Springs, and San Rafael Mines. A GIC design adaptable to the four sites is proposed based on three zones: recreational–passive, services and cultural. The design prioritises sustainability, considering four criteria: political–economic, social, cultural and environmental. The proposal takes advantage of the area’s natural materials and the natural climatic conditions to offer a space that improves the geotourism experience in mimicry with the environment, promoting cultural roots and community benefit.

Actualmente las pequeñas y medianas empresas de base tecnológica (PyMEBTs) tienen la necesidad de desarrollar tecnologías para comercializarlas, y para ello tienen que invertir grandes cantidades de dinero en actividades de I+D+i (Investigación + Desarrollo + innovación), sin la garantía de obtener una tecnología que asegure el éxito de la empresa. Una forma de poder ahorrar tiempo y dinero en estos procesos, es aprovechar el repositorio de patentes que existe mundialmente, tal como lo hacen las empresas transnacionales, y rediseñar las patentes existentes convirtiéndolas en nuevas patentes o modelos de utilidad para su comercialización. Bajo este paradigma, el objeto de esta investigación es hacer la propuesta de una metodología para aprovechar el reservorio mundial de patentes y modelos de utilidad, para impulsar el desarrollo tecnológico de las PyMEBTs mexicanas. <strong>ABSTRACT</strong> Currently, small and médium technology-based companies (SMEBTs) have the need to develop technologies to market them, and for that they have to invest large amounts of money in R + D + i activities (Research + Development + innovation), without the guarantee to obtain a technology that ensures the success of the company. One way to save time and money ¡n these processes is to take advantage of the patent repository that exists worldwide, as transnational companies do, and to redesign existing patents by converting them into new patents or utility models for their commercialization. Under this paradigm, the purpose of this research is to propose a methodology to take advantage of the global reservoir of patents and utility models, to boost the technological development of Mexican SMEBTs.

Abstract. The Earth’s ecosystem is facing serious threats due to the depletion of natural resources and environmental pollution. To promote sustainable practices and formulate effective policies that address these issues, both experts and non-expert stakeholders require access to meaningful Open Data. Current Earth monitoring programs provide a large volume of open Earth Observation (EO) data typically organized and managed in EO Data Cubes (EODCs). From these datasets, satellite-derived indices can be calculated for assessing various environmental aspects in areas of interest over time. However, current EOs lack semantics and are isolated from significant Web resources, greatly hindering their comprehension and limiting their use to specialized users. To enhance EO data with semantic richness and ensure their understanding by a wider audience, it is pertinent to adopt a Linked Open Data (LOD) approach. In this paper, we present the Linked Earth Observation Data Series (LEODS) framework designed to publish aggregated EO data in the LOD Cloud. LEODS provides a processing chain that converts EO data into EO-RDF data cubes based on a spatio-temporal modeling approach that ensures integration and future semantic enrichment of EO data while preserving the advantages of traditional EODCs and following the FAIR principles (i.e., findable, accessible, interoperable, and reusable). To highlight the advantages of our proposal, we explore through SPARQL queries and visualizations, the results of implementing LEODS with study areas located in Switzerland and France.

Background: Women are highly motivated and receptive to accept Family Planning (FP) methods during the postpartum period. Intrauterine Contraceptive Device (IUCD) is one of the commonly used reversible methods of contraception and provide very effective, safe and long-term protection against pregnancy and the health risks associated with the method are negligible. Taking advantage of the immediate postpartum period for counselling on family planning and IUCD insertion, overcomes multiple barriers to service provision. The increased institutional deliveries are opportunity to provide women easy access to immediate PPIUCD services. Objective-The aim of the study was to determine proportion of women accepting postplacental intrauterine contraceptive device insertion, and to describe the factors associated with acceptability and non-acceptance.Methods: Cross-sectional study conducted from September 2021 to October 2021 in 250 women admitted for delivery at Gadag institute of medical sciences, Gadag. The respondents were interviewed using structured interviewer administered questionnaire.Results: In the study, it is found that overall awareness regarding PPIUCD in the study population is only 32% which is comparable with the study findings of Rajasthan where the 8 awareness was 20.2%. The readiness rate for PPIUCD insertion after the counselling in present study was 8% which is similar the study report from Government Medical College, Trissur, Kerala where the acceptance rate 1 was 10.5%. The major factors associated with nonacceptance were refusal by patient (50%) and relatives.Conclusions: The emerging factors for less acceptance of PPIUCD are low literacy rate among women and infrequent counselling and education during antenatal period. Integration of a PPIUCD counselling service at every delivery point with provision of couple counselling can improve the success of this programme.

Abstract. While predicting human and vehicle trajectories is a deeply investigated field of research, predicting aircraft trajectories remains a less explored frontier. Still, the long-term prediction of aircraft movements is a fundamental challenge in aviation, influencing Air Traffic Management (ATM), operational efficiency, and flight safety. Traditional trajectory prediction models are often primarily focused on a 2D prediction.With this work, we evaluate different data representation methods in the field of long-term aircraft trajectory prediction using a state-of-the-art mobility prediction method, namely a CVAE-LSTM. We show that the H3 grid presents advantages for this task. With that, we explore a fascinating field of future mobility research, as the used data allows for various technical analyses without implying threats to personal privacy-relevant information.

Full textAbstract:
Abstract. Parking management plays a critical role in keeping urban spaces accessible and urban managers strive for an optimal balance between not enough and too much parking. Deciding which parking space can be liberated or needs to be extended requires detailed data on parking occupancy trends. In person inspection and in-situ sensors can provide such data but are too costly for city wide deployment. High-resolution satellite imagery is becoming more affordable, has the advantage of instantaneously collecting information from the whole city, is continuously being updated, and available for several years now to allow building a time series. Yet, identifying cars in satellite imagery is not a trivial task. We propose a method for classifying parking spot occupancy based on thresholding the reflectance range. The method requires individual parking spot data to be available and analyses each parking zone individually. We tested the method on a 0.5 metre resolution image (Pleiades satellite) that was specifically ordered for this purpose during a clear spring day in a medium-size city. The method has the advantage of not requiring extensive training data and is non-parametric. To assess accuracy, we collected ground truth data for the exact same moment as the image was ordered. The colour bands (blue, green, and red) performed equally well, while NIR seriously underperformed. We achieved a F1 score of 0.82 for all parking spots in the ground truth. The method is sensitive to tree canopy. When removing the tree obscured spots, the F1 score increased to 0.85. Tree canopy spots were automatically determined and filtered using NDVI.

Full textAbstract:
Industrial wastes are often used as aggregate in concrete production to promote a more sustainable construction and to reduce production costs. This article presents the results of an experimental campaign on the influence of replacing natural aggregate with several construction and demolition wastes (C&DW) as recycled aggregate, as well as the use of fly ash and slag, wastes produced in Gas Incinerator Combined Cycle (GICC) thermal power plants, in the mix design of non-structural concrete. Different percentages of natural aggregates were substituted with recycled aggregates either coming from construction and demolition wastes, or from the coarse fraction of the slags from thermic plants in the manufacture of concrete. The mechanical properties, capillary water absorption, density, carbonation, chloride ingress and sulphate resistance have been tested. The results show a decrease in properties when C&DW are used. Fine fraction of slag and fly ash has an important advantage, and can even improve the long term properties of concrete prepared with natural aggregates. Coarse fraction of slag as a recycled aggregate generally improves most of the properties of manufactured concretes.

Abstract. The planning of health care facilities and the analysis of the medical care situation are complex topics that generally involve geographical and, specifically, settlement topographical, methodological, data-driven aspects. However, formal analyses and planning in the field of healthcare usually only touch on the aspects or do not fully include some of them. As a result, the complex situation is often not accurately. This paper addresses the multidimensional challenges planners and analysts face. Solutions to overcome these hurdles thanks to improved data availability and more advanced technical and methodological possibilities are presented. For this purpose, a Web-Application is proposed that enables planners without GIS knowledge to interact with method components via parameter adjustments. Subsequently, it is examined whether the technical prerequisites for the implementation of a Web-Application for health planning, in particular for outpatient demand planning and analysis, are given and make a proposal for implementation. Finally, the advantages, disadvantages and possible complications of using this Application in health planning and analysis, including critical points of implementation, will be addressed.

Abstract. Hexagonal Discrete Global Grid Systems (DGGS) offer significant advantages for spatial analysis due to their uniform cell shapes and efficient indexing. Among the three central place apertures (3, 4, and 7), aperture 7 subdivisions exhibit very desirable properties, including the preservation of hexagonal symmetry and the formation of unambiguous indexing hierarchies. Interest in hierarchically indexed aperture 7 hexagonal DGGS has recently increased due to the popularity of the H3 DGGS. But there are currently no open-source equal-area aperture 7 hexagonal DGGS available, that provide similar indexing capabilities like H3. We present IGEO7, a novel pure aperture 7 hexagonal DGGS, and Z7, its associated hierarchical integer indexing system. In contrast to H3, where cell sizes vary by up to ±50% across the globe, IGEO7 uses cells of equal area, making it a true equal-area DGGS. IGEO7 and Z7 are implemented in the open-source software DGGRID. We also present a use case for on-demand suitability modeling to demonstrate a practical application of this new DGGS.

Full textAbstract:
AbstractThe gold immunochromatography assay (GICA), a new immunochromatography technique, uses a nitrocellulose membrane as a carrier and a colloidal gold-labeled antigen or antibody as a tracer (bioreceptor). This technology has many advantages over other immunoassays, including its simplicity, rapidity, cheapness, and the lack of a requirement for special training or expensive equipment, and it can be used to detect either antigens or antibodies. Therefore, we chose to develop this method for the diagnosis of candidiasis in Indonesia. The objective of the present study was to develop a diagnostic test for Candida albicans in rats using the GICA method. GICA bioreceptors were developed from biofilm antigens isolated from biofim Candida albicans grown on the surface of nitrocellulose membranes. The formation of biofilms was confirmed using scanning electron microscopy. Antigen levels as bioreceptors were optimized by using the immuno dot method. The samples to be analyzed were antibody serum, in the form of blood serum samples from heart mice that have been induced to become candidiasis. To this end, we optimized the antigen and antibody volumes necessary to make this diagnosis. The results show that the optimum concentration of antigen to be used in the test is 2.5 μg/μL and the optimum volume of antibody is 10 μL. The control rats produced a single red stripe on the control line and the candidiasis rat samples produced a double red stripe, with the bottom line being the control line and the upper line the test line. The test chip was successfully used for the diagnosis of candidiasis in rats and given the name “Candiday Kit.”. We anticipate that this test will be suitable for the diagnosis of candidiasis in humans

Abstract. The Internet of Things is a multi-sensor technology with the unique advantage of supporting non-intrusive and non-device occupancy detection, while also allowing us to explore new forecasting occupancy models. However, forecasting occupancy presence is not a trivial task, since it is still unknown the main criteria in selecting a forecasting modelling approach according to a non-intrusive sensing strategy. Towards this challenge, this paper proposes an analytical workflow developed to support the Prophet model for forecasting occupancy presence in indoor spaces throughout the tasks of sensing, processing, and analysing event triggered data generated from ten non-intrusive sensors, including motion, temperature, luminosity, CO2, TVOC, sound, pressure, accelerometer, gyroscope, and humidity sensors. The usefulness of this analytical workflow is demonstrated with the implementation of an IoT platform for an experiment operating non-intrusive sensing in a classroom. The assessment is made at different time intervals and the results confirm that there is a relationship between the event-count and occupancy presence in such a way that the larger the number of events triggered in an indoor space, the higher the probability of an indoor space being occupied.

Abstract. Localisation and navigation technologies have vastly evolved during the last years, facilitating users’ guidance in various environments. Unlike outdoor environments where GNSS comprises a universal solution, in indoor environments various localisation techniques have been used, each one with its drawbacks. Thus, this research investigates the reliability of the ceilings towards indoor localisation, by using components that are included in a simple mobile device. The choice of ceilings lies in their advantages, which include the incorporation of various characteristic components, as well as the absence of obstacles between them and the sensor. Indoor localisation is achieved based on LiDAR point clouds and images from RGB sensors of mobile devices. Additionally, this research involves location tracking of different users, to discover different movement patterns in an indoor facility. The proposed methodology revealed the robustness of the Coloured ICP algorithm for in-door localisation based on point clouds, both in terms of time efficiency and quality, while the combination of the SURF feature detector and SIFT descriptor provides the optimal indoor localisation results with image data. The proposed pipeline revealed encouraging results for use in emergencies, based on static data acquisition of a user, while it is also suitable for dynamic applications, in case a sensor is mounted on an automated device for indoor mapping operations. The captured point clouds of the ceilings can also be used as a reference to CAD and BIM models, to help the modelling of the existing utilities and their components in an indoor facility.

Abstract. Globally, transport accounts for around one- fifth of CO2 emissions. However, , leveraging the DF data in modeling hyperlocal traffic CO2 and exploring the potential environmental justice is still underexplored. Here, we first extract traffic flows from the DF data, including individual GPS tracks, traffic counts, and car ownership rates in Glasgow, UK, then redefine the spatial relationship by incorporating traffic flows into the Spatial Weight Matrix (SWM), and finally predict the hyperlocal traffic CO2 based on customized SWM. We find that, compared to traditional distance-based SWM, incorporating the real traffic flows into the SWM could better predict hyperlocal traffic emissions, with the Manski model performing best (R2 = 0.62). Besides, the Manski model shows that income and car ownership rates are dominant factors related to traffic CO2. Based on this, we reveal two aspects of environmental justice: 1). Distribution inequality - the high-income areas also have higher levels of car ownership rates, indicating higher barriers and challenges for low-income communities; 2). Contributor inequality - most high traffic CO2 emissions are produced by nearby affluent areas with high car ownership rates, whereas the low-income areas suffer more traffic emissions produced by them, which indicates that disadvantaged groups bear the costs of emissions disproportionately generated by the advantaged. This pilot study explores the application of DF data in environmental monitoring, carbon justice, and climate mitigation to create an equitable and sustainable living environment.

Using quantitative methods, data were collected from 170 employees of PT Ciputra Development Tbk's "The Taman Dayu" and Green Eleven Residential properties. The SEM-PLS analysis revealed significant direct effects, with GOC (β=0.302, t=4.180, p<0.001) and GIC (β=0.369, t=5.625, p<0.001) both positively impacting GCA. GHRM showed a substantial direct effect on GCA (β=0.282, t=4.485, p<0.001) and served as a significant mediator, with GIC's indirect effect through GHRM being β=0.130 (t=3.574, p<0.001) and GOC's indirect effect being β=0.103 (t=3.150, p=0.002). The model explained 64.8% of GCA variance (R²=0.648) and 51.2% of GHRM variance (R²=0.512), demonstrating moderate predictive power. These findings highlight that GHRM can mediate the relationship between GIC and GCA directly; on the other hand, Green Human Resource Management (GHRM) can mediate the relationship between Green Organizational Culture (GOC) and Green Competitive Advantage (GCA) effectively. To create a Green Competitive Advantage, organizations need to integrate GHRM with broader and long-term green strategies. Human resource management of environmentally oriented companies must result in the organization's ability to absorb knowledge from the organization's dynamic external environment to be combined with existing knowledge and form new knowledge so as to create new knowledge.

SARS-CoV-2 is a positive-stranded RNA virus, the seventh coronavirus known to infect humans. Given the infectious nature of SARS-CoV-2 and its wide-reaching effects, finding a valid treatment is a top global priority. Although several vaccines have been used, the uncertainty remains unpredictable. Considering this, early diagnosis of SARS-CoV-2 is a prerequisite for effective containment and timely treatment, allowing doctors to intervene to prevent further spread and disease worsening. This study aims to provide references regarding the advantages and disadvantages of currently developing Covid-19 detection. This research is a Systematic Literature Review (SLR). The database analyzed in this study is in the 2019-2022 timeframe obtained from Google Scholar sources using Harzing's Publish or Perish for Windows version 8 search engine. Based on an article review, the Covid-19 detection test kits are grouped into 3, namely: acid-based detection methods nucleic acid (RT-PCR, dPCR, mNGS, RT-LAMP, CRISPR), serology-based detection methods (ICG/GICA, CLIA, ELISA, LFIA), and diagnostic CT imaging. Each method developed has its advantages and disadvantages. RT-PCR has always been the gold standard for detection. Other diagnostic techniques are also useful. Their combined results can exclude false negatives and positives as much as possible.

In doing so Popper rejected subjectivist views on probabilities which asserted that probabilistic sentences express the degrees of certainty of our hypotheses. In section I, the historical background of the controversies on the nature of probability will be presented. In section II, the problems relating to the falsification of the probabilistic hypotheses are discussed. Sections II and IV are devoted to the subjectivist and logical interpretations on probabilities, and to the arguments that Popper presented against those interpretations. Finally, in section V a discussion about the advantages of the propensity theory over the frequency theory is entertained. <strong>Keywords</strong>: Philosophy: Philosophy of Science; induction and probability: Inductive Logic.

With the advancement of technology, the use of remote sensing and geographic information system has increased in detecting the nature of ground water in hard rock system. Ground water exploration is performed with the help of satellite to know the status of ground water. Delineation of groundwater can be done easily with the help of geographic information system. There are many features which are used for the assessment of ground water resources. Some of these features are slope, groundwater recharge and discharge. The big advantage of remote sensing over hydro-geological survey is that in the former method, the cost is moderate. The current article highlights the role of remote sensing & GIS approach in detecting ground water behavior in hard rock aquifer system.

Although not all introductions of non-native species have negative effects, many of the non-native species can have undesirable effects on biodiversity from the genetic level to the landscape. This work aimed to present the current knowledge on biological invasions by species and particularly on invasive <em>Cryptostegia madagascariensis</em> Bojer ex Decne. New introductions are made every year around the world and only a small part of these taxa become invasive, yet cause serious damage to ecosystems invaded. The success of weed plants is due to the intrinsic characteristics of these species that ensures the same competitive advantages with native species and the level of disruption in new niches which makes them totally supportive environments to establish new species and the emergence of monodominadas areas. In this context is <em>C. madagascariensis</em>, origin of climbing on the island of Madagascar in Africa, which was introduced in Brazil with ornamental purposes, becoming invasive in natural ecosystems, especially in riparian environments and humid lowlands, in the field of savanna and associated ecosystems.</p><p style="text-align: justify;"><strong>Key words</strong>: Exotic species, Caatinga, salination, deficit hydride.</p>

Full textAbstract:
To facilitate the automation of crane operations for grabbing coil stacks in port storage areas, thereby streamlining the processes of warehousing, stacking, and transshipment for enhanced operational efficiency, this paper utilizes algorithms related to 3D point clouds for the pose estimation of coil workpieces. To overcome the limitations of the traditional point pair feature (PPF) algorithm, a novel point cloud registration algorithm is introduced. This algorithm harnesses the advantages of the PPF algorithm in describing local features and integrates it with the Generalized Iterative Closest Point (GICP) algorithm to enhance the robustness and applicability of registration. Finally, comparative experiments demonstrate that the proposed algorithm delivers superior performance. The average pose estimation errors for one, two, and three coils are 1.1%, 1.1%, and 1.2% of the coil size, respectively, with total processing times of 3.6 s, 3.4 s, and 4.7 s, meeting the practical application requirements in terms of accuracy and timing.

Full textAbstract:
In this paper we present a new way to compute the odometry of a 3D lidar in real-time. Due to the significant relation between these sensors and the rapidly increasing sector of autonomous vehicles, 3D lidars have improved in recent years, with modern models producing data in the form of range images. We take advantage of this ordered format to efficiently estimate the trajectory of the sensor as it moves in 3D space. The proposed method creates and leverages a flatness image in order to exploit the information found in flat surfaces of the scene. This allows for an efficient selection of planar patches from a first range image. Then, from a second image, keypoints related to said patches are extracted. This way, our proposal computes the ego-motion by imposing a coplanarity constraint between pairs <point, plane> whose correspondences are iteratively updated. The proposed algorithm is tested and compared with state-of-the-art ICP algorithms. Experiments show that our proposal, running on a single thread, can run 5× faster than a multi-threaded implementation of GICP, while providing a more accurate localization. A second version of the algorithm is also presented, which reduces the drift even further while needing less than half of the computation time of GICP. Both configurations of the algorithm run at frame rates common for most 3D lidars, 10 and 20 Hz on a standard CPU.

<strong>RESUMEN</strong> El Bienestar Animal incluye una relación armoniosa del animal con el medio, donde los estados físicos y psicológicos del animal juegan un papel primordial. La más racional contribución para entender el concepto de Bienestar Animal proviene de las llamadas “<em>Cinco libertades</em>” para el bienestar de los animales. Dado lo reciente de su concepción científica, los estudios no son abundantes pero sí prometedores. El campo de investigaciones científicas que se abre es amplio, más cuando se plantea que debe aplicarse a toda la escala zoológica, lo que pone de relieve a la fauna silvestre como sujeto de investigación. En el caso de los reptiles, los estudios son de relevancia por su indomable comportamiento y por la producción de veneno. En los intentos por aprovechar la herpetofauna silvestre, ésta debe ser manejada en granjas de crianza, zoológicos, vivarios, o terrarios bajo los conceptos de Bienestar Animal. La falta de experiencias en estudios previos sobre el bienestar de reptiles restringe las acciones al no tener parámetros con los cuales comparar. En particular, es necesario que las investigaciones sobre serpientes consideren como tesis de trabajo la naturaleza del animal, su funcionamiento y sus sentimientos, contemplando métodos de fisiología, ecología, y psicología animal, pero también de ética en la relación humano-animal. Metodológicamente, una de las trabas para el avance de los estudios recae en las débiles hipótesis de trabajo que orienten el desarrollo de las investigaciones y la escasez de resultados con los cuales establecer comparaciones. <strong>ABSTRACT</strong> The concept of Animal Welfare includes the existence of a harmonic relationship between the animal and its environment, where the animal physical and psychological states play an important role. The most rationale contribution to the understanding of the Animal Welfare concept comes from the so-called <strong>“</strong><em>Five Freedoms for Animals</em><strong>”</strong>. Due to its recent scientific conception, studies in the field are not very abundant but promising. Therefore, the field of scientific research that this concept opens is wide, and it is envisage to apply to the entire zoological scale, which highlights wildlife as a research subject in animal welfare. On the issue of herpetology, and particularly in the case of reptiles and snakes, studies are relevant due to their indomitable behavior and for their importance as a source of venom. If attempts are to take advantage by using the reptile fauna, animals should be managed under the concepts of Animal Welfare. The lack of experiences restricts the actions, having few parameters and results to compare. In particular for snake investigations, it is necessary to consider as a working thesis the nature of the animal, its functioning and its feelings. The studies on Animal Welfare open up to an underworked scientific activity, where physiological, ecological and psychological methods are to be used, considering the ethics of the human-animal relation. Methodologically, impediment to the advancement of these kind of studies lies in the weak elaboration of working hypotheses, and the absence of previous experiences.

Full textAbstract:
Mapping and assessment of ecosystem services (ES) is a complex activity which includes spatial data acquisition, its organization into databases and generation of maps for the areas of ES supply and demand. GIS is an integral part of these activities and plays key role for the mapping and assessment of ES. There is a significant advance in the development of various tool and models for mapping and assessment during the last decade. The use of GIS in ecosystem services mapping can take three general approaches, analysis tools built into GIS software packages, disciplinary biophysical models applied for ecosystem service assessment and modeling tools designed specifically for ecosystem service assessment. This paper presents the main advantages of the GIS application in these three approaches through analysis of the available tools, models and techniques. The applications are illustrated by examples of mapping works in different areas in Bulgaria.

Currently, conventional enzyme immunoassays which use manual gold immunoassays and colloidal tests (GICTs) are used as screening tools to detect Treponema pallidum (syphilis), hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus type 1 (HIV-1), and HIV-2 in patients undergoing surgery. The present observational, cross-sectional study compared the sensitivity, specificity, and work flow characteristics of the conventional algorithm with manual GICTs with those of a newly proposed algorithm that uses the automated Bio-Flash technology as a screening tool in patients undergoing gastrointestinal (GI) endoscopy. A total of 956 patients were examined for the presence of serological markers of infection with HIV-1/2, HCV, HBV, and T. pallidum . The proposed algorithm with the Bio-Flash technology was superior for the detection of all markers (100.0% sensitivity and specificity for detection of anti-HIV and anti-HCV antibodies, HBV surface antigen [HBsAg], and T. pallidum ) compared with the conventional algorithm based on the manual method (80.0% sensitivity and 98.6% specificity for the detection of anti-HIV, 75.0% sensitivity for the detection of anti-HCV, 94.7% sensitivity for the detection of HBsAg, and 100% specificity for the detection of anti-HCV and HBsAg) in these patients. The automated Bio-Flash technology-based screening algorithm also reduced the operation time by 85.0% (205 min) per day, saving up to 24 h/week. In conclusion, the use of the newly proposed screening algorithm based on the automated Bio-Flash technology can provide an advantage over the use of conventional algorithms based on manual methods for screening for HIV, HBV, HCV, and syphilis before GI endoscopy.

Los resultados indican que la gestión de recursos humanos se transforma de manera integral, es decir, en todas sus áreas. Por otro lado, se identificó que es una preocupación para las empresas el transformar sus procedimientos para generar una ventaja competitiva. Es por lo anterior que se detectó una importante relevancia sobre el tema, particularmente durante y posterior a la pandemia. <strong>ABSTRACT</strong> The Strategic Management of Human Resources through the use of applied technology has become one of the least explored areas in scientific research, observing that during the COVID-19 pandemic its usability has been increasing. In order to analyze the relevance between human resources management and its alignment with strategic planning, as well as the digital transformation of operational and administrative processes, this bibliometric review was carried out in the Scopus database, to discover the most used trends with a view to a strategic alignment, considering an exclusion procedure that allowed refining the analysis framework. The results indicate that the management of human resources is transformed in an integral way, that is, in all its areas. On the other hand, it was identified that it is a concern for companies to transform their procedures to generate a competitive advantage. It is for this reason that an important relevance on the subject was detected, particularly during and after the pandemic.

Full textAbstract:
Giant intracranial aneurysms (GIAs), defined as those exceeding 25 mm, represent a subset of cerebrovascular lesions with significant potential for morbidity due to mass effect and rupture. Compression of cranial nerves, particularly the oculomotor nerve (N. III), by these aneurysms can lead to debilitating symptoms such as ptosis, ophthalmoplegia, and diplopia. Endovascular management, including coiling and stenting, offers minimally invasive treatment options, but the optimal approach remains a subject of ongoing investigation. We present a case of a 28-year-old male with a giant aneurysm of the right cavernous sinus who presented with progressive right oculomotor nerve palsy, characterized by marked ptosis and visual impairment. Initially scheduled for stent placement, the patient underwent endovascular coiling following diagnostic digital subtraction angiography (DSA). Serial neurological assessments and follow-up DSA evaluations were conducted to monitor treatment efficacy and aneurysm stability. In conclusion, this case demonstrates that endovascular coiling can be a valuable therapeutic strategy for giant cavernous sinus aneurysms manifesting with oculomotor nerve compression. Despite the theoretical advantages of stenting in promoting aneurysm obliteration and reducing mass effect, coiling facilitated significant and sustained clinical improvement, specifically the resolution of ptosis and amelioration of visual deficits in this patient. This case underscores the importance of individualized treatment planning in the management of complex intracranial aneurysms.

Present study is focused on the satellite image processing by means of SAGA GIS. The objective of the study is assessment and analysis of the core urban areas and its spatial distribution in the limits of the city and suburbs. The study area includes Yaoundé and its surroundings, Republic of Cameroon. The methodology includes Object Based Image Segmentation (OBIS) approach by SAGA GIS. The paper presents a methodologically structured workflow used in SAGA GIS for segmentation of the Sentinel-2A image. The segmentation techniques includes adjusting technical parameters, performing neighborhood approach and post-processing procedures (unsupervised classification, number of clusters). The OBIS model and SAGA GIS were used as main methods and machine learning techniques for image segmentation. Data include Sentinel-2A satellite image with high resolution (10 m). The image was analyzed by two approaches of cell neighborhood analysis: Moore and Neumann. The results showed following numerical parameters of the computed area: the perimeter of 1,060,560 km and an area estimated for the Yaoundé city 191,745,000 km2. The Neumann approach demonstrated better results for image clustering. The results presented automatically detected and separated segments of the city areas and other land cover types (savannah, forests, mountains). The spectral reflectance of various land cover types on a satellite image enables to group pixels of the image into classes using segmentation technique which has an important impact on the conceptual methodology of the urban mapping. The results of the image segmentation show the average values of the Neumann approach more correct in urban area than Moore approach. The accuracy assessment demonstrated 74.63% for the core urban area by using the Neumann method. The applicability of SAGA GIS for automated methods of image processing using machine learning algorithm of OBIS is presented and the advantages are discussed. The study demonstrated the effectiveness of the high-resolution Sentinel-2A for socio-economic studies, exemplified by urban mapping where remote sensing data serve as reliable sources of geoinformation. The advantages of the OBIS are discussed with detailed explanation of the SAGA GIS workflow.

The use of Geographic Information Systems (GIS), which have developed rapidly in recent years, in archaeological sites provides a basis for many studies. It is important to produce the permanent records of archaeological sites for the management cultural heritage. While many methods are used to produce permanent records and boundaries, photogrammetry and remote sensing techniques have begun to be preferred within the process by considering their advantages such as low cost, saving time, and completing studies on cultural heritage without contact. In this study, a Digital Elevation Model (DEM) and Orthomosaic were produced using an Unmanned Aerial Vehicle (UAV) in Anemurium Ancient City located in Mersin province. These data were used as a basis, and a relational database was created for GIS. Thus, an inventory study of all stone buildings and roads in the area was conducted, and the data sets were created according to the quality of the remains. Furthermore, the stone buildings in the ancient city were named on an address basis, and a relational database including the boundaries of the country, province, district, and ancient city area was created. This study serves as a guide for studies to be conducted on the management of archaeological sites.

Full textAbstract:
Landsat-TM of 2001 covering Iceland (15.5°W-21°W, 64.5°N-67°N) was processed using SAGA GIS for testing distance-based Vegetation Indices (VIs): four approaches of Perpendicular Vegetation Index (PVI) and two approaches of Transformed Soil Adjusted Vegetation Index TSAVI. The PVI of vegetation from the soil background line indicated healthiness as a leaf area index (LAI). The results showed that the reflectance for vegetation has a linear relation with soil background line. Four PVI models and two TSAVI shown coefficients of determination with LAI. The dataset demonstrate variations in the calculated coefficients. The mode in the histograms of the PVI based on four different algorithms show the difference:-7.1,-8.36, 2.78 and 7.0. The dataset for the two approaches of TSAVI: first case ranges in 4.4.-80.6 with a bell-shape mode of a histogram (8.09 to 23.29) for the first algorithm and an irregular shape for the second algorithm with several modes starting from 0.11 to 0.2 and decreasing to 0.26. SAGA GIS permits the calculation of PVI and TSAVI by computed NDVI based on the intersection of vegetation and soil background. Masking the NIR and R, a linear regression of grids was performed using an equation embedded in SAGA GIS. The advantages of the distance-based PVI and TSAVI consists in the adjusted position of pixels on the soil brightness line which refines it comparing to the slope-based VIs. The paper demonstrates SAGA GIS application in agricultural studies.
