Future-proof electricity prices for consumers
Authors: Bergaentzlé Claire , Keles Dogan
Published: August 2023

European electricity systems are undergoing unprecedented changes in response to the profound transformation of our modes of production from fossil fuels to decarbonised energy, to our shift to electricity for heating and transport, the emergence of decentralised energy sources (e.g. solar PV on the rooftop), and to the gas crisis we face. In response, the price formation and signals sent by both the electricity markets and the networks are changing, too. This article summarizes how the energy transition and the latest developments in the energy market affect prices and what policies and regulations can be introduced to keep energy consumption affordable.
Signal of harm in morphine use in adults with acute pulmonary oedema: A rapid systematic review
Authors: Hendrikse C , Ngah V , Kallon I I , Thom G , Leong T D , Cohen K , McCaul M
Published: August 2023

Background. Heart failure affects nearly 65 million people globally, resulting in recurrent hospital admissions and substantial healthcare expenditure. The use of morphine in the management of acute pulmonary oedema remains controversial, with conflicting guidance and significant variation in practice. Synthesised evidence is needed to inform standard treatment guidelines and clinical practice.
Objective. To determine whether morphine should be used in the treatment of acute pulmonary oedema (APE) in adults.
Methods. A rapid review of systematic reviews of randomised controlled trials or observational studies, and then randomised controlled trials, was conducted searching three electronic databases (PubMed, Embase, Cochrane Library) and one clinical trial registry on 12 February 2022. We used a prespecified protocol following Cochrane rapid review methods and aligned to the National Standard Treatment Guidelines and Essential Medicines List methodology. We first considered relevant high-quality systematic reviews of randomised controlled trials or observational studies, then (if required) randomised controlled trials to inform time-sensitive or urgent evidence requests, clinical practice, policy, or standard treatment guidelines.
Results. We identified four systematic reviews of observational studies. The two most relevant, up-to-date, and highest-quality reviews were used to inform evidence for critical outcomes. Morphine may increase in-hospital mortality (odds ratio (OR) 1.78; 95% confidence interval (CI) 1.01 - 3.13; low certainty of evidence; six observational studies, n=151 735 participants), resulting in 15 more per 1 000 hospital deaths, ranging from 0 to 40 more hospital deaths. Morphine may result in a large increase in invasive mechanical ventilation (OR 2.72; 95% CI 1.09 - 6.80; low certainty of evidence; four observational studies, n=167 847 participants), resulting in 45 more per 1 000 ventilations, ranging from 2 more to 136 more. Adverse events and hospital length of stay were not measured across reviews or trials.
Conclusion. Based on the most recent, relevant and best-available quality evidence, morphine use in adults with APE may increase in-hospital and all-cause mortality and may result in a large increase in the need for invasive mechanical ventilation compared to not using morphine. Recommending against the use of morphine in pulmonary oedema may improve patient outcomes. Disinvesting in morphine for this indication may result in cost savings, noting the possible accrued benefits of fewer patients requiring invasive ventilation and management of morphine-related side-effects.

Background. Beta-adrenergic receptor blocker (BARB) drugs are a wide range of medicines that are used in various conditions, including chronic heart failure (HF). Several studies have reported a wide-ranging inappropriate use of evidence-based beta-blockers (EBBBs) in chronic HF in both inpatients and outpatients.
Objectives. To assess the utilisation and optimisation of EBBBs among patients with HF who presented with a reduced ejection fraction (HFrEF).
Methods. A hospital-based retrospective cross-sectional study was carried out at the Adult University Teaching Hospital (AUTH), in Lusaka, Zambia, where patient medical files for the period of 1 July 2018 to 31 July 2021 were reviewed. Patient information, including file number, age, sex, type of BARB and the dose used, was recorded on the developed and validated checklist. Multivariable regression analysis was performed to identify factors associated with utilisation of BARBs.
Results. Of the 173 medical records reviewed, BARBs were utilised in 101 (58.4%) patients. Among the patients who utilised BARBs, 96 (95.0%) were taking EBBBs, while the rest (n=5, 5.0 %) were taking atenolol, which is a non-EBBB. Among the patients who were on EBBBs, none of them received the optimal dose. Age ≥65 years (adjusted odds ratio (aOR) 0.3, 95% confidence interval (CI) 0.17 - 0.64), previous hospitalisation (aOR 0.3, 95% CI 0.13 - 0.51) and furosemide dose ≥40 mg (aOR 0.4, 95% CI 0.21 - 0.64) were significantly associated with lower likelihood of BARB utilisation. New York Heart Association (NYHA) class II (aOR 3.4, 95% CI 1.08 - 10.7), NYHA class III (aOR 4.8, 95% CI 1.65 - 13.7) and patients using at least 5 medications (aOR 5.0, 95% CI 2.91 - 8.77) were independent predictors of BARB utilisation.
Conclusion. This study showed that 95.0% of chronic HF patients were utilising EBBBs, and none received the optimal dose as recommended in the guidelines. Pharmacotherapy with EBBBs should be optimised among patients with chronic HfrEF, as these drugs reduce both morbidity and mortality.

Authors:   , Jurenoka Svetlana
Published: August 2023

In adaptive learning management systems, study information is presented using a defined curriculum and content representation requirements. The drawback of these systems is associated with the methodology for assessing the acquired knowledge, where knowledge validation modules are used to assess the achievements of the learner in a specified period. During the implementation of the learning process, forgetting of knowledge is observed, which affects the learner’s level of knowledge at the end of the learning process. The research domain of the Doctoral Thesis is related to adjusting the adaptive curriculum to the learner’s level of knowledge and the ability to master the study content.

Published: August 2023

Premature ovarian insufficiency (POI) affects 1% of women under 40 years old and represents one of the main causes of infertility in females of childbearing age. POI is a primary ovarian defect resulting from follicular depletion and/or ovarian dysfunction caused by a compromised ovarian somatic cell compartment. Etiologically, ovarian dysfunction could be caused by certain diseases, including infections and autoimmune disorders. There could also be iatrogenic factors such as chemotherapy, radiation, or surgery. The related surgical risks are due to the possibility of disrupting the blood supply to the ovary and/or a subsequent inflammatory reaction. To date, it is unclear whether and how the impaired oxygen delivery and inflammatory environment may influence the basic functions of human ovarian somatic cells. In this study, we used an immortalized human granulosa cell line (COV434) as a model to investigate the effect of exposure to low oxygen levels (hypoxia) and inflammatory conditions on granulosa cell proliferation, apoptosis, and steroidogenesis. The results showed that both hypoxia (5% O2) and proinflammatory cytokine treatment (a combination of TNF-α, IL-1β, IFN-γ and IL-6) significantly increased apoptosis, suppressed proliferation, and affected estradiol secretion in COV434 cells. Our data suggest that granulosa cells could be particularly sensitive to changes in the local environment caused by oxygen deprivation and chronic inflammation.
Polycyclic Aromatic Hydrocarbons (PAHs) in Bulgarian Coals: Occurrence, Distribution and Carcinogenicity
Authors: Kostova Irena , Apostolova Denitsa , Stefanova Maya
Published: August 2023

The study fills the informative gap on occurrence, distribution, and carcinogenicity of polycyclic aromatic hydrocarbons (PAHs) in Bulgarian coals. It presents quantitative data for content and carcinogenicity of PAHs in different rank raw coals from eight basins with geological age from Late Carboniferous to Late Miocene, Ro=0.17–5.20%. The high amounts of alkylated naphthalene and alkylated phenanthrene determined in the bituminous coals reflect the diagenetic conversion of the plant-derived terpenoids into alkylated PAHs.

In this first systematic study of PAHs in Bulgarian raw coals three concentration ranges are established: for Miocene/Eocene age coal – from 1.08 mg/kg to 5.79 mg/kg; for Late Cretaceous/Late Carboniferous age coal – from 77.9 mg/ kg to 137.2 mg/kg; and, for the Late Carboniferous coal – 1.85 mg/kg. The relationship of the total PAHs content vs. raw coal Ro shapes as a “bell” and matches with the published data for the native PAHs from all over the world provenance. The maximal PAHs amount of 137.2 mg/kg at Ro =0.96% for the Late Cretaceous coal lies within the “oil-generation window”, Ro =0.5–1.3% for the kerogen. For all raw coal studied relatively low carcinogenicity is determined based on the well correlated values for B[a]Peq and TEQ parameters.

Published: August 2023

The aim of the present study was to determine the somatotype of adult Bulgarian patients with type 1 diabetes mellitus. Sixty male and 60 female patients aged 20 to 40 years were involved in the study. A sample of healthy Bulgarian individuals (40 females and 40 males) in the same age range as the patients was used as a control group. The measurements were done by direct anthropometry. The Heath–Carter anthropometric method was used to rate the somatotype components of each participant. The mean somatotype of the female diabetic patients was mesomorphic endomorph (endo 5.37; meso 4.51; ecto 1.42). The endomorphic component was dominant, followed by the mesomorphic component and the ectomorphic component with the lowest rating. The mean somatotype of the control females was balanced endomorph (endo 3.74; meso 2.81; ecto 2.98). The endomorphic component was dominant, but the mesomorphic and ectomorphic components were equally presented. The values of endomorphic and mesomorphic components were significantly higher in the female patients than in the healthy women. In males, both the diabetic patients and control individuals presented with endomorphic mesomorph somatotype: patients (endo 3.94; meso 4.66; ecto 2.37) and controls (endo 4.34; meso 5.19; ecto 2.22). The mesomorphic component was dominant, followed by the endomorphic component and the ectomorphic component was with the lowest rating. The mesomorphic component was significantly greater in the healthy males than in the male patients.

Published: August 2023

Nephrotic syndrome is the most frequent glomerular disease in childhood. Steroid resistant nephrotic syndrome (SRNS) represents about 20% of children with nephrotic syndrome. SRNS is one of the leading indications for performing renal biopsy in children. The objective of this retrospective study is to determine the histological patterns of SRNS in Bulgarian children and to compare them with the worldwide findings. The study included 49 patients with SRNS. All biopsies were performed at the Department of Pediatric Nephrology and Dialysis, University Children's Hospital, Sofia, Bulgaria between January 2004 and January 2020. The renal biopsies were examined histologically and with immunohistochemistry at the Pathology Department, Military Medical Academy, Sofia and Medical University – Sofia, Bulgaria. Twenty-eight boys (57.1%) and 21 girls (42.9%) were included in the study. The age at diagnosis ranged from 8 months to 212 months (17 years and 8 months) with a mean of 94 months (7 years and 10 months). Generalized edema was the most common presentation – 55.1%, followed by microhaematuria – 53.1% of cases. Histological examination revealed several different forms: Focal segmental glomerulosclerosis (FSGS) in 30.6% (n=15), Mesangial proliferative glomerulonephritis (MesPGN) in 14.3% (n=7), Membranous glomerulonephritis (MGN) in 12.2% (n=6), IgM nephropathy in 12.2% (n=6), Membranoproliferative glomerulonephritis (MPGN) type I in 8.2% (n=4), C3 glomerulopathy 8.2% (n=4), Minimal change disease (MCD) in 4.1% (n=2), IgA glomerulonephritis in 4.1% (n=2), Diffuse mesangial sclerosis (DMS) in 4.1\% (n=2) and C1q nephropathy in 2.0% (n=1). Although SRNS in Bulgarian children might represent a broad spectrum of glomerular diseases it could be attributed in approximately two/third of patients to four of them – FSGS, MesPGN, MGN, and IgM nephropathy.

Background: The aim of this study was to measure the quality of information about “flatfoot” and “pes planus” presented online on the social media site YouTube and to determine the trends of viewers to medical information on YouTube.

Methods: “Flatfoot and pes planus” was typed into the YouTube search module. From the search results, videos with 50,000 views or more, longer than 45 seconds, and containing information about flatfoot and pes planus disease were selected. DISCERN and JAMA scoring, daily average views, number of likes, and number of comments were collected from 53 videos that met the criteria. The profession of the sharer was evaluated in terms of the information quality of the sharing and the orientation of the audience.

Results: The mean number of views per day of the examined videos was 2,047. The mean video presentation time was 8 minutes 50 seconds. The mean JAMA score was 2 of 4 and the mean DISCERN score was 38.16 of 75. According to the DISCERN score according to the professions, the video quality was moderate for doctors (41.44 ± 12.99), moderate for physiotherapists (41.91 ± 9.04), poor for coaches (32.78 ± 7.87), poor for patients (34.50 ± 5.32), and weak for others (34.89 ± 14.00). According to the Spearman correlation between DISCERN score and mean daily viewing, significant relationships were found for the doctors (P = .0102) and others groups (P = .0033); however, no significant relationships were observed for the physiotherapists group (P = .1073), the flatfoot patients group (P = .5363), and the coaches group (P = .9111). There were significant relationships between like and comment counts in all groups (doctors, P = .0088; coaches, P = .0069; physiotherapists, P = .0007; others, P =.0018; and patients, P = .0066).

Conclusions: Looking at previous studies, it was observed that the quality of online health information was historically inadequate. Likewise, in our study on YouTube, we found that the quality of flatfoot and pes planus information was poor to moderate.

Hanna Dahls roman Kraft (2021) fortæller historien om Olav, som er tidligere medlem af NS og frivillig på Østfronten under 2. verdenskrig. Dahls roman er en af de første førstepersonsfortællinger i norsk litteratur om en overgriber, selvom romanen ikke beskriver de faktiske overgreb. I stedet undersøger romanen Olavs tab af værdighed som følge af hans dom for forræderi efter krigen. Tabet af værdighed er et centralt omdrejningspunkt, som kommer til at dominere Olavs idé om identitet og personlige relationer. I denne forstand forsøger Dahls repræsentation af Olav at undersøge, hvordan 2. verdenskrigs lange eftervirkninger i Norge ikke kun har påvirket ofrenes liv, men også overgribernes liv. Gennem at undersøge, hvordan romanen diskutere arkivets funktioner, spørgsmål om værdighed og narrativ empati, forsøger denne artikel at se nærmere romanens portræt af en overgriber, der forsøger at finde en måde at fortælle sin historie og genvinde sin værdighed i kamp med det omgivende samfund.

Potential of Typha as Plant Candidates for Sludge Treatment Wetlands
Authors: Wu Meiyin
Published: August 2023

Phragmites austrailis have been commonly planted on sludge treatment wetlands due to its high resistance to sludge waste; thus sludge treatment wetlands are commonly referred to as “reed beds”. Phragmites’ aggressive nature and high productivity allow this invasive plant species to form monoculture stands, alter ecosystem processes, outcompete and replace native species. Thus, native alternatives plant species for sludge treatment wetlands is in urgent needs. Typha are abundant and common throughout most of the North America and have high tolerance to various environmental conditions. This study examined the potential of Typha as candidate plants for sludge treatment wetlands. The results suggested Typha has a great potential to replace the invasive Phragmites as an alternative plant species for sludge treatment wetlands due to its ability to sustain repeated sludge application and to efficiently remove solids, phosphorus and nitrogen from the sludge waste.

Authors: Jabalia Neetu , Chaudhary Nidhee
Published: August 2023

Proteases or proteinases are essential constituents for all the existing live forms. They act as important industrial enzymes occupying about 60% of total enzyme market. In the present study proteases extracted from nine medicinally important spices; Carum copticum, Syzygium aromaticum, Cuminum cyminum, Nigella sativa, Cinnamomum verum, Foeniculum vulgare, Zingiber officinale, Cinnamomum tamala and Curcuma longa; used in our food and as household medicines on regular basis, have been investigated. Amongst these spices, the specific activity of the isolated protease enzyme was found to be significantly high in Nigella sativa (204 units/mg) and Curcuma longa (124 units/mg) and therefore, their extract was further partially purified and biochemically characterized. The crude extract of the two spices on being subjected to salt precipitation using (NH4)2SO4 as neutral salt, yielded three fractions at 0-30%, 30-60% and 60-90% saturation level. The specific activity of protease enzyme was found to be highest in 0-30% fraction, obtained from both the sources. The values of specific activity and purification-fold of enzyme from Nigella sativa and Curcuma longa were found to be 409 U/mg, 590 U/mg and 2.0-, 4.8-, respectively. The enzyme showed maximum activity at pH and temperature conditions of 5.0 and 40°C, respectively, at 20 min of incubation time, in both the cases. The pH stability values of protease from Nigella sativa ranged from 5.0 to 9.0 whereas in Curcuma longa values were from 4.0 to 8.0. The enzyme from Nigella sativa and Curcuma longa exhibited resistance against heat treatment upto 60°C and 50°C, respectively, increasing the industrial feasibility. The present work hereby, indicates that Nigella sativa and Curcuma longa may serve as good source of thermostable protease; an enzyme of great relevance in various chemical and bio-industries along with pharma sector.

The optimization and streamlining of certain structures, parts manufacturing combined with high technical qualities (mechanical strength and physicochemical), recycling or reuse of solid wastes, reducing maintenance costs … have motivated the use and development of specific materials whose composition and characteristics accommodate themselves to technological constraints.

The composite materials based on expanded perlite and unsaturated polyester resin (organic resins regenerated), were developed for this purpose. The basic idea is to combine in the same mass of different materials by their chemical and structural natures in order to increase mechanical, physical and / or chemical performance that can facilitate implementation. The composite materials developed during this study are developed from an organic resin associated with expanded perlite and other mineral fillers including marble powder and / or plastic wastes fibers.

Different formulations are performed; taking into account both the proportion of expanded perlite, the nature of the inorganic fillers or reinforcements. The various tests carried out as mechanical and mechanic-chemical properties are reported.

Organotin(IV) compounds have received tremendous attention for their synthesis, characterization and biological activities and their ability to bind with sulfur ligand such as dithiocarbamate ligand. Organotin(IV) dithiocarbamate complexes can be synthesized by the reaction of carbon disulphide with secondary amine. Four new organotin(IV) dithiocarbamate complexes were successfully synthesized by the reactions between di-2-ethylhexyldithiocarbamate, C16H34NCS2 and N-methylbutyldithiocarbamate, C5H12NCS2 with dibutyltin(IV) dichloride and triphenyltin(IV) chloride, RxSnClx (R = Bu, Ph) and (x = 1, 2 or 3). These series of complexes were synthesized using “in situ” insertion method and characterized by determination of melting point, CHNS elemental analysis, infrared spectroscopy (FT-IR) and UV-vis spectroscopy. The melting points of the synthesized compounds were in the range 88.3 - 128.4 °C. The experimental CHNS data of the compounds, mostly exhibit the calculated CHNS values. Using infrared spectra (FT-IR), the formation of organotin(IV) dithiocarbamate complexes were confirmed by the presence of v(C=N+) at 1464 - 1497 cm-1, v(C-S) at 963 - 1025 cm-1 and v(Sn-S) at 412 - 445 cm-1 in all complexes. Besides that, the UV-vis analysis showed the peaks chromophore of N=C within range 259 - 260 nm, nonbonding electron on sulphur and charges transferred between the tin metal and ligand (M-L). Using TGA analysis, complex 1 and 3 show two degradation curve but complex 2 and 4 shows only one degradation curves. The antibacterial activity of all synthesized organotin(IV) dithiocarbamate complexes were then determined towards four types of bacterial strains which were Escherichia coli, Staphylococcus aureus, Salmonella thypi and Bacillus cereus. Penicillin was used as positive control and streptomycin as negative control in order to compare diameter of inhibition zone between both controls and complexes. From antibacterial test, almost all synthesized complexes were found to give positive results. Thus, it can be concluded that the complexes formed do have applications in biological and medical aspects.

Samenvatting

Magnetic and thermal critical behaviors of itinerant electron magnets around the quantum critical point (QCP) have recently attracted much interest. On the other hand, crossover phenomena between classical and quantum critical behaviors have not drawn much attention. The purpose of this study is, therefore, clarifies how the predominance of thermal and quantum critical behaviors will change around the QCP based on the spin fluctuation theory. We show that in the region very close to the Neel temperature T
N
in the paramagnetic phase, the temperature dependence of the inverse of staggered susceptibility obeys the classical (T-TN)2-linear behavior. With increasing temperature T, it changes into the quantum critical (T
3/2
-TN3/2)-linear dependence above the crossover temperature T*. Since T* tends to vanish in the quantum critical limit TN → 0, the classical critical region disappears and predominant T3/2-linear behavior prevails.

Published: August 2023

The open earthen pond system is a cost effective system for the production of microalgae and aquaculture products. Studies are required in the development of compacted earthen liners as cost-effective lining technologies to avoid negative impacts on water resources and human health. The objective of this study was to determine the effect of different levels of compaction and application of a polyacrylamide polymer as a soil sealant on the hydraulic conductivity of soil. Three soils collected from the existing pond sites were packed into aluminum cores (5 cm diameter), proctor molds (10 cm diameter) and stock pots (60 cm diameter) prior to saturated hydraulic conductivity (Ks) determination using the constant head method. A negative relationship was obtained between Ks and compaction for sandy loam, sandy clay loam and loam soils. The application of the soil sealant to compacted soil cores, proctor molds and stock pots did not decrease the Ks to the value of 1 x 10-9 m/s or lower to meet the regulatory criteria of compacted clay liners. The dry bulk density versus Ks curves indicate that sandy loam and sandy clay loam soils should be compacted to 1.82 and 1.69 g/cm3, respectively in soil cores and 2.40 and 1.59 g/cm3 in soil molds respectively to meet the regulatory criteria. The puddling experiments with sandy loam and loam soils in the stock pot also showed decreases in soil hydraulic conductivity as finer particles settle out of suspension in the soil pores. These experiments showed that sandy clay loam and loam soil can be compacted to decrease the Ks below the regularity criteria for clay liners. More experiments particularly in small ponds are needed to validate the results of the laboratory experiments.

Published: August 2023

Preventing pesticide drift from aerial applications is important for environmental and application efficiency reasons. Proper analysis of drift reduction technologies or techniques is an essential component of the drift prevention process. In the current study, three drift reduction adjuvants were tested with two herbicides under several application conditions used by rotary-wing and fixed-wing aircraft in the U.S. Data was collected using a high speed wind tunnel and laser diffraction equipment. The results of the study indicated application conditions, and not adjuvant inclusion, were the largest drivers of the droplet size distribution and drift potential. Data was further computed in the drift prediction program, AGDISP, where little differences were observed between the treatments. This study highlighted the importance of testing drift reduction technologies or techniques from multiple viewpoints.
An Improvement of Velocity Variation with Offset (VVO) Method in Estimating Anisotropic Parameters
Authors: Herawati Ida , Winardhi Sonny , Triyoso Wahyu , Priyono Awali
Published: August 2023

Seismic anisotropy causes deviation of traveltime reflection from hyperbolic moveout. The deviation can be seen at far offset and its deviation depends on anisotropic parameter and offset. This paper discuss velocity variation with offset (VVO) method as a tool for estimating anisotropic parameters; ε and δ. Anisotropic parameter is one of important aspect in seismic anisotropy analysis. While other methods use non-hyperbolic moveout for estimating anisotropic parameter, VVO method uses hyperbolic assumption for moveout correction and leave reflector unflat at far offset because anisotropy. The method calculates residual traveltime and then changes it into anisotropy velocity to obtain anisotropic parameter using linear inversion method. This paper provides an improvement and limitation of VVO method in estimating anisotropic parameter. Comparison between VVO method and other established method is discussed theoretically in this paper. To test the method, synthetic model is built and the result show promising outcome in predicting ε. Meanwhile accuracy for δ estimation depends on accuracy of moveout velocity. Advantage of VVO method is that ε and δ can be estimated separately using P-wave gather data without well information.
MSCDNet-based multi-class classification of skin cancer using dermoscopy images
Authors: Radhika Vankayalapati , Chandana B. Sai
Published: August 2023

Background

Skin cancer is a life-threatening disease, and early detection of skin cancer improves the chances of recovery. Skin cancer detection based on deep learning algorithms has recently grown popular. In this research, a new deep learning-based network model for the multiple skin cancer classification including melanoma, benign keratosis, melanocytic nevi, and basal cell carcinoma is presented. We propose an automatic Multi-class Skin Cancer Detection Network (MSCD-Net) model in this research.

Methods

The study proposes an efficient semantic segmentation deep learning model “DenseUNet” for skin lesion segmentation. The semantic skin lesions are segmented by using the DenseUNet model with a substantially deeper network and fewer trainable parameters. Some of the most relevant features are selected using Binary Dragonfly Algorithm (BDA). SqueezeNet-based classification can be made in the selected features.

Results

The performance of the proposed model is evaluated using the ISIC 2019 dataset. The DenseNet connections and UNet links are used by the proposed DenseUNet segmentation model, which produces low-level features and provides better segmentation results. The performance results of the proposed MSCD-Net model are superior to previous research in terms of effectiveness and efficiency on the standard ISIC 2019 dataset.

The use of offensive terms in user-generated content on different social media platforms is one of the major concerns for these platforms. The offensive terms have a negative impact on individuals, which may lead towards the degradation of societal and civilized manners. The immense amount of content generated at a higher speed makes it humanly impossible to categorise and detect offensive terms. Besides, it is an open challenge for natural language processing (NLP) to detect such terminologies automatically. Substantial efforts are made for high-resource languages such as English. However, it becomes more challenging when dealing with resource-poor languages such as Urdu. Because of the lack of standard datasets and pre-processing tools for automatic offensive terms detection. This paper introduces a combinatorial pre-processing approach in developing a classification model for cross-platform (Twitter and YouTube) use. The approach uses datasets from two different platforms (Twitter and YouTube) the training and testing the model, which is trained to apply decision tree, random forest and naive Bayes algorithms. The proposed combinatorial pre-processing approach is applied to check how machine learning models behave with different combinations of standard pre-processing techniques for low-resource language in the cross-platform setting. The experimental results represent the effectiveness of the machine learning model over different subsets of traditional pre-processing approaches in building a classification model for automatic offensive terms detection for a low resource language, i.e., Urdu, in the cross-platform scenario. In the experiments, when dataset D1 is used for training and D2 is applied for testing, the pre-processing approach named Stopword removal produced better results with an accuracy of 83.27%. Whilst, in this case, when dataset D2 is used for training and D1 is applied for testing, stopword removal and punctuation removal were observed as a better preprocessing approach with an accuracy of 74.54%. The combinatorial approach proposed in this paper outperformed the benchmark for the considered datasets using classical as well as ensemble machine learning with an accuracy of 82.9% and 97.2% for dataset D1 and D2, respectively.

Published: August 2023

This study deals with the Triple Helix development model’s efficient application in managing innovation in public policies in a Brazil-Portugal comparison. The Triple Helix model has its origin in England, to resume the economy in decline and unite the initiatives, until then unilateral, of universities-industries-government. Internationally recognized as a model of innovation and development, Triple Helix uses mechanisms that aim to mitigate the failures existing in universities, industries, and governments, transforming knowledge into practices aimed at the economy and improving the three elements’ interactions. In this sense, the work’s objective is to present how the process of operationalization of public policies aimed at innovation is developed, aligning government, Industry, and universities in a Brazil-Portugal comparison. For its development, bibliographic research and a comparative exploratory study about innovation management in Brazilian and Portuguese public policies were used. As a result, it is confirmed that, with the Triple Helix model in innovation management, public policies focused on science and technology is more effective. Even more, the greater the involvement between the three actors of the development model.
