Linking Entities from Text to Hundreds of RDF Datasets for Enabling Large Scale Entity Enrichment

There is a high increase in approaches that receive as input a text and perform named entity recognition (or extraction) for linking the recognized entities of the given text to RDF Knowledge Bases (or datasets). In this way, it is feasible to retrieve more information for these entities, which can be of primary importance for several tasks, e.g., for facilitating manual annotation, hyperlink creation, content enrichment, for improving data veracity and others. However, current approaches link the extracted entities to one or few knowledge bases, therefore, it is not feasible to retrieve the URIs and facts of each recognized entity from multiple datasets and to discover the most relevant datasets for one or more extracted entities. For enabling this functionality, we introduce a research prototype, called LODsyndesisIE, which exploits three widely used Named Entity Recognition and Disambiguation tools (i.e., DBpedia Spotlight, WAT and Stanford CoreNLP) for recognizing the entities of a given text. Afterwards, it links these entities to the LODsyndesis knowledge base, which offers data enrichment and discovery services for millions of entities over hundreds of RDF datasets. We introduce all the steps of LODsyndesisIE, and we provide information on how to exploit its services through its online application and its REST API. Concerning the evaluation, we use three evaluation collections of texts: (i) for comparing the effectiveness of combining different Named Entity Recognition tools, (ii) for measuring the gain in terms of enrichment by linking the extracted entities to LODsyndesis instead of using a single or a few RDF datasets and (iii) for evaluating the efficiency of LODsyndesisIE.

Transformation of Selected Fusarium Toxins and Their Masked Forms during Malting of Various Cultivars of Wheat

This study investigated the impact of malting of six wheat cultivars inoculated with Fusarium culmorum on the dynamics of content changes of selected Fusarium toxins. The grains of all the tested cultivars showed a high content of deoxynivalenol (DON), zearalenone (ZEN), and their derivatives, whereas nivalenol (NIV) and its glucoside were found only in the Legenda cultivar. Our experiments confirmed that the malting process of wheat grain enables the secondary growth of Fusarium, and mycotoxin biosynthesis. The levels of toxins in malt were few-fold higher than those in grain; an especially high increase was noted in the case of ZEN and its sulfate as the optimal temperature and pH conditions for the biosynthesis of these toxins by the pathogen are similar to those used in the grain malting process. This is the first paper reporting that during the malting process, biosynthesis of ZEN sulfate occurs, instead of glycosylation, which is a typical modification of mycotoxins by plant detoxication enzymes.

Effect of a health claim on consumer acceptance of milk-based dessert containing omega-3

This study was to evaluate the influence of information on the addition of omega-3 and its health benefits in the acceptance of dairy dessert. The hedonic thresholds methodology was applied in two trials: blind and open-label. In the blind trial, no information was provided to consumers regarding the formulation of the flans. In the open-label trial, consumers received the information on the addition of omega-3 and its health benefits. The value of compromised acceptance threshold (CAT) was not influenced by the information on the addition of omega-3 and its health benefits. However, there was a high increase in the value of hedonic rejection threshold (HRT) when the consumers were informed of the benefits of omega-3, and it was possible to increase the addition of the compound in the flans by up to 21.03% without causing product rejection, confirming the positive effect of information on health benefits in accptance.

Distribution of minerals between orange juice and orange flesh in various cultivars

The aim of this study was to evaluate the distribution of essential and toxic elements between the orange juice and orange flesh of various orange cultivars. Different orange cultivars, such as Abousorah [Citrus sinensis (L.)], Aseear (Citrus aurantium), Afandi (Citrus reticulata Blanco), Helo (Citrus sinensis), and grapefruit (Citrus paradisi), were collected from local markets. Elemental analysis was carried out after microwave-assisted digestion using inductively coupled plasma mass spectrometry (ICP-MS) in 18 samples. Eleven elements (V, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Cd, and Pb) were analysed. Their average concentrations ranged from 0.006 µg g^–1 to 7.13 µg g^–1 in both orange juice and flesh (wet weight). There was a high increase in the average concentrations of all elements in the juice compared to the flesh of up to 40-fold.

Geohistorical, didactic, and linguistic competencies learning through a bilingual (Spanish/English) fieldtrip project with teachers in training

This research is predicated on the hypothesis that a fieldtrip project adhering to a CLIL (Content and Language Integrated Learning) philosophy can be effective in promoting learning of both social and linguistic competencies. The main objective was to evaluate the didactic efficacy of a bilingual urban itinerary with teachers in training (from bilingual and non-bilingual groups) to develop geohistorical, didactic and linguistic competencies. Procedural and consolidated learning was assessed, via a dossier of activities and a statistically validated pretest-posttest. High development values were obtained in procedural tasks (average = 8.8/10), as well as a high increase in consolidated acquisition (average = +24.5% students). The greatest growth was observed in language skills (+ 26.4%). The assessed knowledge after the itinerary was significantly higher than before, for all competencies. However, there was no statistically significant difference between students belonging to bilingual or monolingual groups. Students positively valued these results. It is concluded that a local didactic fieldtrip is an effective CLIL strategy to develop social and linguistic competencies, and yet it is rarely discussed in the scientific literature and curricula.

Continuous fentanyl infusion reduces intra-abdominal pressure, postoperative pain and normalizes lungs’ mechanical changes in newborn with viscera-abdominal disproportion in early post-operative period

We aimed to study the influence of prolonged administration of fentanyl on postoperative pain, intra­ab­dominal pressure and mechanical lungs’ changes that may happen in neonates in early post­operative period. 30 newborns (in the period from January 2017 to May 2021) with gastroschisis were divided into two groups ac­cordingly to the method of analgesia (14 – morphine hydrochloride; 16 – prolonged infusion of fentanyl). Lungs’ mechanical characteristics, effectiveness of post­operative analgesia, abdominal wall relaxation was studied by monitoring of dynamic compliance (Cdyn), pressure and flow­volume loops, capnography. Apprising analgesia sta­tus, we measured hemodynamic, SаO2, blood level of cortizol, C­reactive protein (CRP), glucose, analyzed post­operative pain syndrome using visual analogue scales (VAS). Intra­abdominal pressure (IAP) was controlled by Cron. For statistic analysis we used Student’s t­test. In the group with morphine, thete was the increase of IAP by 11–12 cm H2O, being stable during some period of time, and also variable levels of pain according to VAS, the in­creasing of CRP from 0.8 ± 0.25 mg/dl by 5 mg/dl, cortisol by 674.4 nmol/l, and blood glucosae rate – 7.4 mmol/l. Periods with high traumatic effects and poor analgesia (morphine group) reasoned the increasing IAP, step by step dynamic compliance decreasing in 3.4 times, resistance increasing in 2.42 times and PIP rising till 22 cm H2O. Di­rect correlation between IAP increase and lungs’ mechanical changes took place. The study has demonstrated that prolonged administration of fentanyl prevented high increase of IAP, CRP, levels of glucose and cortizol and changes of VAS data, lungs’ mechanical characteristics.

Solidification Effect and Mechanism of Marine Muck Treated with Ionic Soil Stabilizer and Cement

In this study, an environmentally friendly ionic soil stabilizer (ISS) was adopted with combination of Portland cement to stabilize a marine muck. The macro and micro tests results demonstrated that the ISS was an effective stabilizer to improve the strength of marine muck when it was used combined with cement after adding the alkalizer NaOH. Except for the reduction in interlayer distance of clay minerals by ISS, Ca2+ and SO42− dissolved from ISS promoted the production of ettringite (AFt), pozzolanic and carbonation reactions of Portland cement in the presence of NaOH. Meanwhile, the hydration products of curing reaction notably agglomerated soil particles, which caused an obvious decrease of pores and a high increase of strength for solidified soils. Furthermore, this combination of stabilizers can not only save the dosage of cement, but also accelerate the solidification speed, decrease the cement setting time within 7 days to meet the curing requirements, and enhance the strength of solidified soils.

Impact of Long-Term Weathering on the Properties of a Digestate-Based Biocomposite

Natural fibre composites are increasingly used. For many applications, the long-term stability of the mechanical properties is crucial. Therefore, the effects of weathering of a biocomposite made from fibrous digestate and bio-based thermoset are investigated. The fibre component of the composite comes from digestate of a German biogas station which processes hop vines as main substrate. The matrix is a plant-oil-based epoxy resin. The samples were alternately exposed to UV radiation and moisture for various lengths of time. Afterwards, the material strength and water absorption were tested. As a result, the weathering leads to a decrease of strength but not to a high increase of water uptake.

Feasibility of STEM-based basic chemistry teaching materials to improve students’ science literature in wetland context

Development research has been carried out to produce teaching materials for basic chemistry learning materials based on STEM in a wetland context to improve scientific literacy that is valid, practical, and effective. This type of research is Research and Development (R & R&D) with a 4D development model modified into 3D (define, design, and develop). The trial of the developed teaching materials was carried out in a class in the first Basic Chemistry course consisting of 28 students. Data collection techniques used validation sheets, readability questionnaires, response questionnaires, observation sheets, and scientific literacy tests. Data analysis used descriptive analysis. The results showed that the developed teaching materials had met the following criteria: (1) Valid; judging from the value of the feasibility aspects of content, presentation, language, and media, each of which obtained very valid criteria. (2) Practical; reviewed from the results of the readability of teaching materials in individual and small group tests, the criteria are practical and very practical. Students’ responses to teaching materials have very practical criteria, and observations of the ability of teachers to use teaching materials and manage their respective classes get very good criteria. (3) Effective, seen from the results of the N-gain scientific literacy showing a high increase. With the results of this development, it can be said that the STEM-based teaching materials for basic chemistry learning to improve scientific literacy in the context of wetlands are suitable as teaching materials.

Ciri-ciri akustik tuturan gagap: Kajian fonetik akustik

This study aims to formulate the acoustic characteristics of stuttering speech through the acoustic phonetic approach. The parameters used to determine the acoustic characteristics of stuttering speech are the duration of speech and silence, the speech tone contours, and the intensity contours of the speech. The data used in this research is a documentary data taken from the website www.youtube.com. The research data is in the form of stuttering speech with phonetic transcription [bəbəbəp bəbəp bəbəbəp bəlaki]. The data were analyzed using Praat 1.6.26 software. The results show that the analyzed stuttering speech has some acoustic characteristics as follows: (1) it has a different duration per sound segment and tends to increase in the last sound segment which is influenced by the length of the lexical strands and the slow movement of the speakers articulator; (2) it has silences with varying duration between one sound segment and another, which indicates that a stuttering speech is spoken haltingly and often stops suddenly; (3) it has a fairly flat tone contour in the first, second, and third segments, and has a significant increase in tone contour in the last sound segment; and (4) it is spoken louder in the last sound segment compared to the previous sound segment which is characterized by a high increase in sound intensity in the last sound segment.
