Published: March 2023

Many researchers currently employ supervised, machine learning methods to study sentiment analysis. Analysis can be done on movie reviews, Twitter reviews, online product reviews, blogs, discussion forums, Myspace comments, and social networks. Support Vector Machines (SVM) classifiers are used to analyze the Twitter data set using different parameters. The analysis and discussion were undertaken to allow for the conclusion that SVM has been successfully implemented utilizing the IMDb data for this study (Support Vector Machine). To complete this study, the preprocessing phase, which consisted of filtering and classifying data using SVM with a total of 50.000 data points, was completed after collecting up to 40.000 reviews to use as training data and 10.000 reviews to use as testing data. 25.000 positive and 25.000 negative points make up the view. In this study, we adopted an evaluation matrix including accurate, precision, recall, and F1-score. According to the experiment report, our model achieved SVM with Bags of Word (BoW) used to get results for the highest accuracy test, which was 88,59% accurate. Then, using grid-search, optimize against the SVM parameters to find the best parameters that SVM models can use. Our model achieved Term Frequency–inverse Document Frequency (TF-IDF) was used to get results for the highest accuracy test, which was 91,27% accurate.
Sineu Pinkout! Promoción turística, conflicto político y renovación festiva en la Mallorca rural
Authors:   Universitat de Barcelona (España), Vives Riera Antoni , Obrador Pons Pau ,   Northumbria University (Reino Unido)
Published: March 2023

In this article, we propose to analyse the role of tourism promotion in the social and political con‑ flict in the rural municipality of Sineu (Mallorca) between 2013 and 2014 with respect to the celebration of the festivities in honour of their patron saint. In this sense, we emphasize that the emergent festival of La Mucada proposed by young left‑wingers has meant a ritual and performative practice of de‑essentialization of the tourist “otherness” as defended by the right‑wing authorities. At the same time, the inclusive nature of the new festivity and local identity has facilitated tourist participation and integration into the process of political change. This shows that tourism plays a central role in local political conflicts, beyond strict dia‑ metrically opposed stances of for or against, and can be an element of symbolic power to be conquered by various different social and political actors.

Authors: Yahaya Zwanden Sule , Giwa Lisha , Dagogot Charles Na’anman , Orugun Oluwaseun Adenike , Adeleye Olutayo Ademola , Mohammed Boma Blessing
Published: March 2023

Objectives:

The aim of this work is to assess the suitability of Parkia biglobosa mucilage (PBM) as a suspending agent in metronidazole suspension.

Methods and Materials:

Metronidazole suspension was formulated with mucilage (0.1%, 0.5%, 1%, and 2% w/v) from P. biglobosa seeds as the suspending agent. Similar suspensions of metronidazole that contained (0.1%, 0.5%, 1%, and 2% w/v) tragacanth or gelatin were also prepared for comparison to PBM-based formulations. The suspensions were assessed for rheological properties, sedimentation volume, degree of flocculation, ease of redispersion, flow rate (flowability), and drug-excipient compatibility using Fourier-transform infrared spectroscopy.

Results:

Brownish metronidazole suspensions with a smooth and elegant appearance were obtained. After 2 weeks of storage at ambient temperature (28 ± 2°C), the ease of redispersion was in the following order: tragacanth < PBM < gelatin-containing formulations. The optimal pH of the formulation was slightly acidic and did not significantly change (p > 0.05) after 3 months of storage at ambient temperature (28 ± 2°C). However, the viscosity of the formulations was reduced by more than 30%, and the flow rate was significantly increased (P < 0.05). Suspensions formulated with 2% PBM were well-flocculated and easily redispersible. Furthermore, the sedimentation volume and sedimentation rate of suspensions formulated with 2% PBM were comparable to that of tragacanth- and gelatin-containing suspensions.

Conclusion:

PBM hence has great promise as a suspending agent for pharmaceutical preparations.

Published: March 2023

Background:

Cerebral aneurysms are not common among children and most of them are presented with subarachnoid hemorrhage or mass effect. Here, we describe a rare case of a pediatric giant aneurysm presented with cerebral infarction.

Case Description:

A 38-month-old boy visited the emergency room due to left hemiparesis and left central type facial palsy. Initial magnetic resonance imaging showed acute cerebral infarction on the right basal ganglia and coronal radiata. Furthermore, a thrombosed aneurysm with a diameter of 30.57 mm at the frontal branch of the right middle cerebral artery was observed. A right pterional craniotomy with Sylvian dissection was performed. Superior and inferior divisions of the frontal branch originating from the aneurysm were identified. The superior division was cutoff from an aneurysm and clipping saving the inferior division was done. Subsequently, end-to-end anastomosis was done between a parietal branch of the superficial temporal artery and a superior division from the aneurysm. No acute complication from the operation was observed. Motor power of the left upper extremity recovered after rehabilitation, while fine motor impairment remained 6 months after the surgery.

Conclusion:

This case illustrates successful treatment of a pediatric giant aneurysm with extremely rare presentation of cerebral infarction, under a meticulous surgical plan and ad hoc modification.
Management of business processes of the organization in the context of digital transformation
Authors: Zheregelya A. V.
Published: March 2023

The article is devoted to the analysis of the modern organizations’ digital transformation trend and its constituent factors. The organizational changes of Russian companies that use a digital tool for intermittent organizational and economic processes in order to increase the effectiveness of their activities and management efficiency are considered in most detail. The author notes the versatility of the digital transformation process of a modern organization in the context of organizational change aspects determined by digital technologies as a tool for innovation. The article is based on the methodology of an integrated approach and system analysis. The theoretical basis of the article was the publications of Russian researchers devoted to aspects of the digital transformation of the organization. Familiarization with regulatory documents and government programs, methods of comparative analysis were chosen as research methods. The method of expert assessments, normative and logical methods were also used. It has been determined that the structure of the resource potential of digital technologies for Russian enterprises and organizations is a wide range of opportunities to influence both the labor process, the process of forming technological and professional digital competencies of employees and managers, and the organizational ecosystem as a whole. The study showed that the institutional field of the organization’s business model with the inclusion of digital technologies in it allows creating new formats of interaction both within the organization (manager-employees) and in the external environment (for example, in working with partners and clients). However, this process may collide with the existing narratives of the organization’s operating principles, including the existing organizational / corporate culture, with its values, which to a certain extent determines the effectiveness of its implementation. It is concluded that the change in value priorities in the new digital reality will be based on the implementation of specific systemic measures, which are presented by the author in ten areas. According to the author, the information presented in the article will make it possible to specify the management of the organization’s business processes in order to increase the effectiveness of its activities.
Dumbbells, chains, and ribbons: anisotropic self-assembly of isotropic nanoparticles
Authors: Lavagna Enrico , Salassi Sebastian , Bochicchio Davide , ROSSI GIULIA
Published: March 2023

Functionalizing the surface of metal nanoparticles can assure their stability in solution or mediate their self-assembly into aggregates with controlled shapes. Here we present a computational study of the colloidal aggregation of gold nanoparticles (Au NPs) isotropically functionalized by a mixture of charged and hydrophobic ligands. We show that, by varying the relative proportion of the two ligands, the NPs form anisotropic aggregates with markedly different topologies: dumbbells, chains, or ribbons. In all cases, two kinds of connections keep the aggregates together: hydrophobic bonds and ion bridges. We show that the anisotropy of the aggregates derives from the NP shell reshaping due to the formation of the hydrophobic links, while ion bridges are accountable for the “secondary structure” of the aggregates. Our findings provide a general physical principle that can also be exploited in different self-assembled systems: anisotropic/directional aggregation can be achieved starting from isotropic objects through a soft moldable surface.

Authors: Swain Sharada Prasanna , Mahanta Chandra Sekhara , Maurya Madan , Mandal Debabrata , Ravichandiran V. , Parihar Vipan
Published: March 2023

Sphingosine-1-phosphate (S1P) is a signal transmitter. The lipid sphingosine is converted to S1P by catalysis of Sphingosine kinase enzymes (SK1 or SK2). S1P acts extracellularly as a receptor ligand. The SK1/S1P axis plays important roles in cell signalling, the cell death/survival, the production of a pro-inflammatory response, and maintaining vascular integrity. There are five subtypes of S1P receptor known as S1P1, S1P2, S1P3, SP4, and S1P5. Glycosphingolipids promote viral entry. The drug molecules targeting the SK1/S1P axis such as fingolimod, ozanimod, and ponesimod are used for treatment of multiple sclerosis. S1P receptor modulator drug fingolimod shows antiviral activity against human immunodeficiency virus. Currently, the clinical trials of ozanimod (a sphingosine receptor modulator), and opaganib (a SK2 inhibitor) are being conducted for treatment of COVID-19. It is worth to target SK/S1P pathway to develop antiviral drugs, by repurposing existing inhibitors/modulators, and designing new specific inhibitors of SK1, SK2, and SP receptor.

Kilka uwag o prerogatywie Prezydenta Rzeczypospolitej Polskiej do nadawania orderów i odznaczeń
Authors: Kubacki Oskar
Published: March 2023

Przedmiot badań: Problematyka nadawania orderów i odznaczeń przez Prezydenta RP nie cieszyła się do tej pory szerokim zainteresowaniem polskiej opinii publicznej. Ostatnimi dniami jednak ten stan rzeczy uległ chwilowej zmianie. Obecnie urzędujący prezydent odznaczył bowiem Orderem Orła Białego posła sprawującego mandat. Fakt ten wywołał szerszą dyskusję na temat sposobu wykonywania prezydenckiej prerogatywy w zakresie nadawania orderów i odznaczeń.

Cel badawczy: Głównym celem artykułu było udzielenie odpowiedzi na pytanie, czy nadając ordery i odznaczenia prezydent jest związany przepisami ustawy o orderach i odznaczeniach, czy też może nadawać je zupełnie swobodnie, niezależnie od kryteriów wskazanych w ustawie. W tym kontekście autor artykułu szczególną uwagą obdarzył art. 3 ustawy o orderach i odznaczeniach, zgodnie z którym nie można wnioskować o nadanie wyżej wymienionych wyróżnień wobec aktualnie urzędujących posłów i senatorów. W dalszej części artykułu autor rozważył czy prezydent może wręczyć wyżej wskazanym politykom odznaczenia wówczas, gdy działa z urzędu. Drugim głównym celem pracy było wyjaśnienie, czy naruszenie przez prezydenta przepisów ustawy może skutkować pozbawieniem osoby odznaczonej przyznanego jej orderu lub odznaczenia.

Metoda badawcza: W artykule wykorzystano metodę dogmatyczno-prawną. Oparto się przy tym zarówno na analizie tekstów aktów prawnych, jak i opracowaniach naukowych oraz dorobku judykatury.

Wyniki: Na skutek przeprowadzonych badań ustalono, że prezydent posiada swobodę w nadawaniu orderów i odznaczeń. W ramach tej prerogatywy prezydent nie jest związany wolą żadnego innego organu. Prezydent musi jednak przestrzegać przepisów ustawy o orderach i odznaczeniach. Nie może on także nadać orderu lub odznaczenia urzędującemu posłowi lub senatorowi. Nadanie przez prezydenta orderu lub odznaczenia z naruszeniem przepisów ustawy nie daje jednak podstaw do odebrania tego wyróżnienia osobie odznaczonej.
Common stochastic features and their economic interpretation
Authors: Majsterek Michał
Published: March 2023

Background: Cointegration analysis has been part of the research literature for almost 40 years. However, other common features that cause disequilibrium of economic categories have so far attracted less attention. This leads to an interesting question about the degree to which studies in the alternative fields are substitutive or complementary, and what conditions must be met in order to undertake the appropriate analysis (cointegration, co-cyclical, co-autocorrelation or other, less frequently discussed co-behaviors) is purposeful.

Research purpose: The purpose of this paper is the comparison of different types of common stochastic behaviors. The type of common factors and the resulting analysis of movements that should be chosen, naturally depends on the time horizon, which can be long, medium, or short, but a reliable study should not ignore any of these perspectives. This study tries to demonstrate that the key role in this choice is played by the reduced rank of the most important matrices that occur in the appropriate VAR model representations or the isomorphic representations thereof. Another research goal was to show that the above-mentioned analyses of stochastic co-movements are largely complementary.

Methods: Multidimensional dynamic econometrics based on VAR models was selected for the study because it contains tools that enable the different methods of analyzing common behaviors to be analyzed. Possible combinations of full and reduced cointegrating matrix ranks and the medium- and long-run relationships matrices were considered and economically interpreted. Relationships between the matrices have been identified, and the iterative mechanism that causes the system to return to equilibrium is described.

Conclusions: The study confirms that the analyzed investigations on common dominant components were essentially complementary. Extending the analysis to seasonal cointegration or deterministic co-trending would allow substitutive elements to be revealed. For example, a cointegration analysis using a relatively short time horizon is an alternative to co-trending (the stochastic trend expires only in a very long perspective), and an analysis that considers a more integrated process could be an alternative to co-deterministic cyclical analysis.
Not by Design Alone! Modelling Practices to Identify Students’ Frameworks of Evolution in Real-Life Contexts
Authors: Ageitos Noa , Colucci-Gray Laura , Puig Blanca
Published: March 2023

Despite being a fundamental concept in biology, evolution continues to be one of the most challenging topics to teach in science education. Ideas of evolution emphasising anatomical or behavioural features of individuals, as opposed to the interplay between genetics and the environment, are reinforced through language and culture, making them robust and persistent in the student population at all educational levels. Model-based reasoning has been reported to be useful for students to make sense of process-based science content, combining epistemological with linguistic and value dimensions. However, there is a dearth of evidence in biology education showing how modelling can instigate epistemological maturity, specifically about issues of agency and design in evolution by natural selection. Drawing on this perspective, this study focuses on describing the nature of students’ ideas while modelling the resistance developed by a population of mosquitoes in a lagoon after an insecticide is introduced. Data collection includes students’ written reports and drawings, which were analysed with content and discourse analysis. The findings show that, at first, students believed adaptation to feature at will was a behavioural characteristic instigated by a pre-existing design. After modelling the process of natural selection, the explanations appeared to improve (from Lamarckian to Neo-Darwinian views), and most groups showed accurate explanations about adaptation.
“BELI INDONESIA” MOVEMENT AS BREAKTHROUGH TO MANAGE THE PEOPLE'S ECONOMY IN THE MIDDLE OF LEGAL DEADLOCK IN INDONESIA
Authors: Trenggono Heppy
Published: March 2023

Beli Indonesia can be said to be a political movement, when viewed from a simple political understanding. Politics builds perceptions in order to gain power. The "Beli Indonesia" movement, a purely economic system is not enough to ward off the invasion of foreign products, but a kind of development of positive Indonesian sentiment is needed in all circles. In the midst of the increasingly swift currents of globalization, in the midst of the industrial revolution 4.0 which gave birth to changes in people's economic behavior, in the midst of China's rise which has awakened the awareness of nationalism in the world's nations, we are called to make a real contribution, to contribute to educating the nation. Article 33 of the 1945 Constitution states that the populist economic system is a system for making people sovereign in the economy. The economic system mandated by our constitution is an economic system that involves the widest possible participation of the people, not a monopolistic economic system, not an economic system that accommodates the greed of a few people. Form Beli Indonesia by defending the economy of our own nation's children.

Authors: Ainun Najie Ilyu , Widati Sri , Fattah M. Zainal
Published: March 2023

Traditional media are increasingly marginalized by ‘the new media’ or ‘social media’, which are declared as advanced media. Behind this progress, many studies state that online media causes a lot of misinformation in the community. During the COVID-19 pandemic, people continue to look for sources of information from trusted media, between both media to be used as a reliable reference. This article's objective is to promote public understanding of the COVID-19 pandemic by describing how traditional media played a crucial role in disseminating accurate information and combating rapidly spreading misinformation. The study was a literature study using PRISMA guidelines. Relevant articles included in the analysis were obtained from several scientific databases such as PubMed, SAGE, Science Direct, and PLOS One (published between 2020 and 2021), by using the relevant keywords “traditional media”, “misinformation”, “COVID-19”, then determined by criteria feasibility: (1) scientific journals, (2) research objectives, (3) open access, and (4) research results that are clear and in accordance with research objectives. We come to the conclusion that the majority of the public are understanding of and have a high level of trust in traditional media as a source of credible information during the COVID-19 pandemic and as a guide for preventing the spread of misinformation.

Published: March 2023

Image processing technology is the foundation of the ANPR (Automatic Number Plate Recognition) system. It is one of the crucial methods created to recognise the plate of a vehicle. It is impossible to physically keep track of every car in the modern world due to the daily increase in the number of vehicles. It is now simple to maintain a record and utilise it as needed thanks to the creation of this system. Thus, creating an effective system for automatically identifying vehicles with their licence plates is the key goal. As a vehicle enters the security checking area, the system immediately starts to take pictures of the vehicle. The segmentation procedure is then used to extract the pictures that were collected. To recognise the characters, optical character recognition is utilised. The data collected is then compared to the data kept in their database. Real photos are used to assess the system's performance once it has been constructed and simulated in MATLAB. It is common practise to employ this kind of technology at parking lots, toll booths, and traffic control zones. This system is primarily intended for security system purposes.

Published: March 2023

Even if living against the water is challenging, living with the rising water level is doable. The global average sea level is rising as a result of global warming. The land surface is being occupied by rising water levels. Several places of the globe are in danger of disappearing from the map, vanishing under water, due to rising sea levels. Society will have to adjust and possibly live in floating dwellings one day. Some countries are further along in their adaptation to the effects of global warming, particularly the rising sea level, than others, depending on their geographical location. In locations where the land is mostly covered by water, the sole option to survive the rising waters is floating house. A 96.6m. sq. long floating house with dimensions of 11.5mx8.4m is considered. This paper aims to construct a floating house and use Ansys software to analyse the structure.

Published: March 2023

The Analog-to-Digital Converter (ADC), with its wide variety of applications in the electronics and communication domains, is the most crucial unit in every digital gadget. This paper discusses a smart way of converting an input analog signal to its digital counterpart using an innovative Adaptive-Delta modulator, followed by a signal reconstruction process to retrieve the original message. It has done the design in Matrix Laboratory (MATLAB) Simulink, and the hardware implementation is tested on the Xilinx Spartan-6 LX45 FPGA core. This design aims for high-accuracy conversion and optimization of hardware resources. The 1-bit adaptive model is superior in comparison to the traditional delta modulation (DM) scheme while tracking stiff analog input signals, producing a much lower mean square error. The implementation is quite simple as it uses the transmission of 1-bit digital data at a time. On the receiver side, digital-toanalog conversion (DAC) makes use of the same adaptive logic in reconstructing the original input signal. The designed prototype demonstrates its resistance to a wide range of input amplitude and frequency variations. The ADC-DAC design method in this paper is accurate, makes the best use of resources, and is easy to use.
Impact of climate change by 2030 - indian perspective
Authors: Yadav H. R. P.
Published: March 2023

This paper aims to establish the effect of Green House Gases (GHGs) emissions on climate change. Greenhouse gas molecules formed due to anthropogenic activities absorb infrared radiations from the sun, and these molecules re-emit the radiations in all directions, causing temperature rise of the Earth's surface. Due to anthropogenic activities in the country, GHG emissions of GHGs are increasing. The motor vehicles running in the Indian cities with the fossil fuels like gasoline, diesel, etc., are emitting Carbon-di-oxide (CO2), Hydrocarbon (HCs), Nitrogen oxides (NOx) and water vapor as greenhouse gases in the form of vehicular exhausts. These emissions are responsible for deteriorating ambient air quality of the cities like Delhi, National Capital Region (NCR), Mumbai, Kolkata, Bangalore, Hyderabad, etc. This paper outlines the necessary technologies and practices to mitigate GHG emissions of GHGs. The paper also discusses some of the strategies for reducing emissions of GHGs to minimize the effect of global warming and climate change. The impacts of implementing energy efficiency and conservation measures, the role of renewable energy, and hydrogen blends in the vehicular fuel Compressed Natural Gas (CNG) are also described in this paper. The emission performance of a passenger car suitable for bi-fuel combustion with 18 Hydrogen Compressed Natural Gas (18HCNG) has been compared with neat CNG fuel. The economic analysis with these two vehicular fuels in respect of reducing CO2 and NOx being greenhouse gases, has also been discussed in this paper.
Online teaching during the covid-19 pandemic: how do high school students describe their attitude towards e-learning in bhutanese classroom?
Authors: Kuenzang Dorji , Riku Dhan Subba
Published: March 2023

The COVID-19 pandemic has caused unforgiving disruptions in public education all over the world and brought about coercions of fragmentation in society. In Bhutan too, the continuity of education and learning has been greatly affected as a result of the closure of schools and the imposition of public restrictions and health protocols following the COVID-19 pandemic. E-learning was adopted hurriedly in the country to provide continuous education amid the pandemic lockdown. Therefore, to foresee the acceptance and applicability of e-learning in Bhutanese classrooms, this study focused on examining high school students' attitudes towards e-learning and their preference between classroom learning and online learning. Adopting the simple random sampling technique, 101 high school students who were exposed to e-learning for almost two years were selected as study samples. A purposive sampling technique with preceding information relevant to the study was used to select the sample school. A mixed methods approach was adopted to assemble the data. Grounded theory coding systems, descriptive and inferential statistics were used to analyze the data. The result of the quantitative data revealed that more than fifty percent of the student participants showed a positive attitude towards e-learning. It was revealed that not only perceived usefulness and perceived ease of use influenced the students' favorable attitude towards e-learning but also accessibility to ICT gadgets in their daily lives incurred a positive impact on it. On the contrary, the lack of in-person interaction, the tediousness of prolonged online lessons, and distraction by the play apps were some of the aspects that contributed to having an unfavorable attitude towards e-learning. The result from qualitative data revealed that most of the students preferred classroom learning over online learning based on different motives like classroom learning being more reliable, has in-person interactions, and their prolonged exposure to the classroom approach, which is more realistic. The findings from the study can be handy for curriculum developers, school administrators, and educators while making decisions on the adoption of e-learning.

Authors: Raja Kumar S. , Shirley Moral C.
Published: March 2023

A significant role in educational assessment is played by measuring behavioural changes based on clearly specified educational objectives and meaningfully interpreting the results. One of the most significant strategies for evaluating a student's learning performance in the classroom is formative assessment. Formative assessment systems concurrently improve the science and art of teaching and learning. Teachers can help the students grow as students by actively hopeful them to self-assess their skills, test their knowledge retention, giving clear commands and providing the necessary feedback to put them on track. This paper aims to demonstrate the various Formative Assessment Tools for Effective Classroom. The conclusions derived from the teaching fields are then merged to produce an incorporated summing with clear implications for effective didactic academic performance. The assessment of students by the teachers has a powerful direct impact on their learning performance, which may be positive and thus be worthy of very attractive and fruitful learning.

Published: March 2023

The pandemic caused a vital change in all human beings' lives through income, job, society, and education. The aim of this study is to learn the teachers' outstanding performance in online classes during a pandemic situation. There are numerous studies pertaining to students, but none pertaining to teachers. According to the census, some business people earned more money in the pandemic period. In the medical field, doctors, nurses, and other workers did their best throughout the pandemic period. The teachers struggled a lot because of the online classes. Many teachers working in private sectors suffered a lot without reasonable salaries or no salary. In this study, the investigators aimed to study the teachers' performance regarding online classes during the pandemic period. In everyone's life, there exists an individual difference in all the aspects. The study also shows the acceptance of new methodologies, new situations, and new modes among the teaching community. The findings show that there is no significant difference between male teachers' outstanding performance and female teachers' outstanding performance in their online classes during the pandemic situation. In addition, there is no significant difference among teachers' outstanding performances in their online classes during a pandemic situation with regard to their years of experience. The investigator selects a sample of 19 teachers from the whole population. The investigators used the Teachers' Outstanding Performance Scale to collect the data. From this study, the investigators suggest teachers and professors give outstanding performances in their classes. It provides job satisfaction to them. No background variables can affect the achievement of the learners. Automatically, the outstanding performance leads the teachers and professors to the next mile in their academic process. There is no limitation on the welfare of the student's progress. Moreover, the qualities such as motivating, teaching, student's observation, student's feedback, and the results of the learner increase abundantly among the teachers. Thus, the present study on teachers' outstanding performance in online classes during a pandemic situation helps to take the teachers and professors to their extreme levels of best.

COVID-19 is commonly known as a novel coronavirus disease, which is a highly contagious disease that emerged in China in late 2019. This disease is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is a virus belonging to the large family of coronaviruses. The disease first emerged in Wuhan, China in 2019 and then quickly developed into a global pandemic, spreading to more than 213 countries. The well-known symptoms of COVID-19 are fever, shortness of breath, dry cough, and other symptoms. Pain or difficulty breathing may occur. Most of these symptoms point to signs of respiratory infections and lung abnormalities that can be detected by radiologists. So, chest xray and computed tomography images can be used with machine learning algorithms to find the disease.
Seismic evaluation and rehabilitation of G+1 corroded RC building
Authors: Dheeraj Kumar Singh , Harish Chandra Arora , Shobharam
Published: March 2023

Reinforcing steel corrosion is one of the major cause of degradation in Reinforced Concrete (RC) construction. Corrosion is caused by the processes of carbonation and chloride attack, which results in a reduction in the structural performance of structures over time. The time-dependent corrosion process has an impact on structure safety and serviceability, and it can even lead to progressive failure. Corrosion causes reinforcing bar diameter reductions, concrete fissures, concrete cover expulsion, concrete and steel strength reductions, and the breakdown of the link between the concrete and imbedded steel. When it comes to multistory concrete buildings, corrosion is a considerably bigger issue in terms of seismic performance. As a result, accurately assessing and establishing the current corrosion degree of structural parts, as well as evaluating the local and global seismic capacity of existing corroded RC buildings, has been a major challenge around the world. The current study used a methodology in which revised properties were applied for seismic evaluation and establishing the correct restoration scheme for existing two-story RC framed buildings based on non-destructive and destructive material site as well as laboratory testing. The findings of linear seismic analysis and non-linear static pushover analysis for sound, corroded, and retrofitted buildings have been compared and analyzed and a new corrosion evaluation model is being proposed based on NDT (Non-Destructive Testing) and other established analytical models.

Efficiency of data transmissions with minimum latency levels and better resource utilization is a challenging issue in 5 G device-to-device (D 2D) environments. A novel technique referred to as single linkage steepest gradient gentle AdaBoost cluster-based device (SLSGAC) is introduced to improve device-to-device communications with minimum latency. The proposed technique uses the ensemble clustering approach to group mobile devices by constructing a set of weak clusters, based on the Minkowski single linkage clustering technique. In the weak clustering process, residual energy, bandwidth and SINR are estimated, and mobile devices are grouped based on the Minkowski distance measure. Results of the weak clustering process are combined to provide the final ensemble’s clustering output by applying the steepest gradient function to minimize the error rate. For each cluster, a head is selected from among the group members to improve the data transmission rate and minimize latency. Simulations are conducted comparing the proposed technique with the existing methods based on such metrics as energy efficiency, data delivery ratio, packet loss rate, throughput and latency.

Introduction: Hemodialysis is the main treatment for patients with Chronic Renal Insufficiency and one of the main complications resulting from it is the occurrence of infections caused by opportunistic microorganisms belonging to the “ESKAPE” group. Aim: to determine the frequency of isolation of pathogens from the ESKAPE group and evaluate their respective antimicrobial resistance profiles in hemodialysis patients in a medium and high complexity hospital located in the Amazon. Outlining: Retrospective study carried out with collection of data available in the medical records of 167 patients diagnosed with Chronic Renal Insufficiency, undergoing hemodialysis or peritoneal dialysis from 2015 to 2019 in a regional hospital in the Southeast of Pará. Results: Of the 174 bacteriological cultures analyzed, 70.1% were positive and, of these, 57.4% were positive for bacteria belonging to the ESKAPE group. The most frequent microorganism belonging to the ESKAPE group was Staphylococcus aureus (47.1%); as to the resistance levels, 50% of Acinetobacter baumannii were resistant to carbapenems. Implications: The phenotypic profile of multidrug resistance to antimicrobials in strains of Acinetobacter baumannii was identified, highlighting the importance of knowledge about the profile of sensitivity to antimicrobials for a more assertive treatment and better prognosis.
