Killing it softly – Can soft materials play a strategic role in the eradication of tuberculosis?
Authors: Mejías Víctor , Lopes Cátia D. F. , Batalha Iris Luz
Published: April 2024

Intracellular organelles can be regarded as natural vesicles essential for the organization, isolation, protection, and recycling of macromolecules within cells. Similarly, lipid and polymer-based vesicles can offer compartmentalization through the physical confinement of (macro)molecules in nanoscale dimensions, a key architectural principle to achieve biomimicry and facilitate molecular transport in organelle-like compartments. In the last few decades, the therapeutic scope of soft materials has gained significant traction, particularly in the field of bacterial infections, ranging from the prevention of biofilm formation to the development of new targeted antimicrobial agents and vaccines. This review seeks to highlight and critically discuss the potential of biomimetic synthetic vesicles in the prevention and treatment of Tuberculosis, the deadliest human bacterial infection to date, providing an overview of the clinical progress achieved thus far.

Published: April 2024

Great advances have been made by leveraging high-valent Pd(II)/Pd(IV) catalysis in the areas of C–H activation and alkene difunctionalisation, thus representing a powerful approach for the construction of carbon-carbon and carbon-heteroatom bond. However, the catalytic reactions involving high-valent Ni(II)/Ni(IV) catalysis are largely underdeveloped. Here we report a Ni(II)-catalysed dicarbofunctionalisation of unactivated alkenes via high-valent Ni(II)/Ni(IV) catalysis. This dicarbofunctionalisation protocol provides a highly efficient and direct route towards vicinal substituted alkanes using primary, secondary, and tertiary amides, as well as secondary and tertiary amines as the native directing group under redox-neutral conditions that are challenging to access through conventional methods. The key to the success of this reaction is the use of a bulky β-diketone ligand, which could enable the insertion of alkene to aryl-Ni(II) species, stabilize the alkyl-Ni(II) species and inhibit the homolytic alkyl-Ni(II) cleavage. This dicarbofunctionalisation reaction features the use of native directing group, a broad substrate scope, and excellent scalability. The resulting Weinreb amide-derived products can be readily derivatized to a variety of ketones and aldehyde, which are fundamentally useful in synthetic chemistry. In addition, this protocol has been employed for the efficient preparation of several bioactive compounds, showcasing the significant synthetic values of our current method.

Published: April 2024

Metal-organic frameworks are materials which are constituted by an inorganic centre and organic ligand offering high crystallinity, high surface area and high permanent porosity. These structures show promising results in multiple applications due to their properties, especially their capacity for open-metal sites. The use of these structures for electrochemical applications, such as sensors and electrocatalysts, require their immobilisation on a conductive surface, as they are obtained in powder form using the most common method – solvothermal synthesis. Electrophoretic deposition, an indirect method, which focus on immobilising these materials in powder form postsynthesis on the surface of a conductive structure can be used for their immobilisation, that may offer several advantages in relation with other methods if further developed – those being simplicity and universality. This work focuses on the synthesis, immobilisation, and stability studies of these MOFs in the presence of water and in oxidative aqueous electrochemical medium. The obtained metal-organic framework powders and films were characterised using X-rays diffraction, Fourier Transform infrared spectroscopy and scanning-electron microscopy. The electrochemical studies were made using cyclic voltammetry. It was possible to form films of the MOFs UiO-66, UiO-66-NH2 and Ni-MOF-74 on the surface of fluoride-doped tin oxide glass using electrophoretic deposition, with all three MOF films showing stability in water and the UiO- 66 and UiO-66-NH2 films showing high stability as well in highly basic oxidative aqueous electrochemical medium.
Employing Metadynamics to Predict the Membrane Partitioning of Carboxy-2H-Azirine Natural Products
Authors: Daly Clyde , Seebald Leah , Wolk Emma
Published: April 2024

Natural products have diverse chemical structures and biological activities which often serve as sources of new therapeutic agents. Those containing a carboxy-2H-azirine moiety are an exciting target for investigation due in part to the broad-spectrum antimicrobial activity these compounds have and the significant chemical space for novel therapeutic development offered by this unique scaffold. The carboxy-2H-azirine moiety, including those appended to well-characterized chemical scaffolds, is understudied, which creates a challenge for understanding potential modes of inhibition. In particular, some known natural product carboxy-2H-azirines have long hydrophobic tails, which might lead to amphipathicity and implicate them in membrane associated processes. Metadynamics is an effective method for calculating the free energy changes associated with membrane embedding processes. In this study, we examined a small set of carboxy-2H-azirine natural products, including analogs with long alkyl chains, geometric isomers, and one comprising the simple carboxy-2H-azirine core. We compared the physiochemical properties of these compounds to those of established membrane embedders with similar chemical scaffolds. This was intended to isolate the physiochemical properties of the carboxy-2H-azirine group and understand molecular influences of this moiety on membrane partitioning. To accomplish this, we developed a force field for the 2H-azirine functional group and performed metadynamics simulations of the partitioning into a model membrane (75 % POPE, 25 % POPG) from aqueous solution. We determine that the carboxy-2H-azirine functional group is likely hydrophilic, imbuing the long chain analogs with amphipathicity similar to the known membrane binding molecules to which they were compared. For the long chain analogs, the carboxy-2H-azirine headgroup stays within 1 nm of the phosphate layer, while the carboxy-2H-azirines lacking the long alkyl chain partitions completely into aqueous solution.

Published: April 2024

Aim. To investigate the antitumor effects of human placenta hydrolysate (HPH) peptides on three hormone-dependent human cell lines: prostate adenocarcinoma, breast carcinoma, and ovarian cancer by metabolic analysis of cell cultures.
Materials and methods. The effect of HPH on tumor and control tumor cell lines was evaluated. Study stages: (A) de novo peptide sequencing by collision-induced dissociation mass spectrometry; (B) detection of peptides with anti-tumor properties; (C) expert analysis of the obtained lists of peptides.
Results. Dose-dependent cytotoxic effects of HPH on three tumor cell lines are shown: PC-3 (human prostate adenocarcinomas), OAW-42 (human ovarian cancer), BT-474 (human breast carcinomas), and IC50 constants (1.3–2.8 mg/ml) were obtained. The analysis of the HPH peptide fraction showed more than 70 peptides with antitumor properties in the composition of this HPH, including kinase inhibitors: mitogen-activated protein kinases, kappa-bi nuclear factor inhibitor kinase, AKT serine/threonine kinase 1, protein kinase C zeta, interleukin-1 receptor-associated kinase 4 and cyclin-dependent kinase 1.
Conclusion. The results of the study indicate not only the oncological safety of the HPH used in therapy but also the mild antitumor effects of this HPH at high concentrations.

Chronic obstructive pulmonary disease is now one of the most common noncommunicable diseases and the main causes of morbidity, disability and mortality in the world. In recent years, new approaches to epidemiology, diagnosis, classification (categorization), evaluation of phenotypes, as well as characterization and assessment of the severity of сhronic obstructive pulmonary disease exacerbations have emerged. Modern approaches to starting and subsequent drug therapy have changed significantly. This is largely due to the results of recently conducted major clinical trials, demonstrated high efficacy of triple fixed combinations, including inhaled glucocorticosteroids, long-acting beta-agonists and long-acting anticholinergic drugs. The use of non-medication methods (smoking cessation, physical activity and respiratory rehabilitation) and modern approaches to the treatment of respiratory failure and antibiotic therapy remain important. In terms of their significance, all these updates have a significant impact on real clinical practice and can be considered as a novel paradigm of the approaches to the diagnosis and management of this disease.

Authors: Gottapu Sankara Rao , P. Krishna Subbarao
Published: April 2024

Computer Networks and the internet are essential to our daily lives and enterprises. DoS assaults threaten computer networks and network security. The world is evolving toward online businesses and services. This has increased network traffic over time. We need NIDS and DoS attack detection since there are more network risks and attacks. DoS attacks now threaten computer network servers. This threat must be detected automatically to protect corporate assets. Anomaly-based intrusion detection was developed because signature-based DoS attack and intrusion detection methods are inadequate. Many studies employ Machine Learning and Deep Learning to detect network anamolies. This article describes classification models constructed with the aid of machine learning algorithms. On the own dataset, this research was performed utilizing machine learning algorithms including K-Nearest Neighbor (KNN), Logistic Regression, and Random Forest. Random Forest outperforms other supervised machine learning algorithms, as demonstrated by this study's findings. It achieved an accuracy rate of 99.62% when nine features were selected utilizing Pearson's correlation coefficient method. The own dataset file (myNetworkGenerateTraffic.csv) which was captured through wireshark tool were utilized to accurately evaluate machine learning algorithms. We utilized the following performance metrics in this investigation: Accuracy, Precision, Recall, and F-1 score. In this paper, we examine how machine learning techniques can improve DoS attack prediction in network traffic to better analyze network traffic and help improve network security.
An Ontological Framework for Representing Clinical Knowledge in Decision Support Systems
Authors: Iannaccone Marco , Esposito Massimo
Published: April 2024

In the last decades, clinical evidence and expert consensus have been encoded into advanced Decision Support Systems (DSSs) in order to promote a better integration into the clinical workflow and facilitate the automatic provision of patient specific advice at the time and place where decisions are made. However, clinical knowledge, typically expressed as unstructured and free text guidelines, requires to be encoded into a computer interpretable form suitable for being interpreted and processed by DSSs. For this reason, this paper proposes an ontological framework, which enables the encoding of clinical guidelines from text to a formal representation, in order to allow querying, advanced reasoning and management in a well defined and rigorous way. In particular, it jointly manages declarative and procedural aspects of a standards based verifiable guideline model, named GLM-CDS (GuideLine Model for Clinical Decision Support), and expresses reasoning tasks that exploit such a represented knowledge in order to formalize integrity constraints, business rules and complex inference rules.

Mobility-Aware, Correlation-Based Node Grouping and Selection for Cooperative Spectrum Sensing
Authors: Cichoń Krzysztof , Nardis Luca De , Bogucka Hanna , Benedetto Maria-Gabriella Di
Published: April 2024

Cooperative spectrum sensing has been proposed as a solution to increase the sensing function accuracy in cognitive radio networks, but the research has, so far, mainly focused on static scenarios, all but neglecting the impact of mobility on spectrum sensing. In this work a novel cooperative spectrum sensing scheme for mobile cognitive networks, based on a correlation-based, mobility-aware node selection algorithm is proposed. Correlation among sensing decisions is used to divide nodes into groups, and mobility is taken into account in the group leaders selection by means of a node selection metric that considers both sensing performance and mobility. Performance of the proposed algorithm is evaluated by computer simulations taking into account mobility and a detailed modeling of temporal and spatial correlation of fading and shadowing components in the channel path loss, going way beyond the performance evaluation carried out in previous works on correlation-based cooperative sensing schemes. Simulation results highlight that the proposed metric leads to a significant increase of the update period required to maintain acceptable sensing performance, and correspondingly to a strong reduction in the overhead caused by the grouping and node selection procedure.
Priority Based Routing for Forest Fire Monitoring in Wireless Sensor Network
Authors: Koga Takuma , Toyoda Kentaroh , Sasase Iwao
Published: April 2024

Recently, forest fire monitoring system in wireless sensor networks has received much attention. The conventional scheme receives fire alert data quickly to inform about fire forest event. However, since two or more nodes may detect a fire, high priority fire detection data frequently collide. In this paper, a new forest fire monitoring system is proposed in order to reduce high priority fire detection data dropped rate, by specifying a high priority received data immediately after fire detection and just before the destruction by fire. Furthermore, the node only transmits high priority data to a node, which has a low possibility of destruction by fire for low end-to-end delay of high priority fire detection data. The simulation results show that proposed scheme can reduce high priority data dropped ratio and the end-to-end delay, and have less effect of wind direction compared with the conventional scheme.
Partner Selection Using Reputation Information in n-player Cooperative Games
Authors: Mariano Pedro , Correia Lu´ıs M. P.
Published: April 2024

To study cooperation evolution in populations, it is common to use games to model the individuals interactions. When these games are n-player it might be difficult to assign defection responsibility to any particular individual. In this paper the authors present an agent based model where each agent maintains reputation information of other agents. This information is used for partner selection before each game. Any agent collects information from the successive games it plays and updates a private reputation estimate of its candidate partners. This approach is integrated with an approach of variable sized population where agents are born, interact, reproduce and die, thus presenting a possibility of extinction. The results now obtained, for cooperation evolution in a population, show an improvement over previous models where partner selection did not use any reputation information. Populations are able to survive longer by selecting partners taking merely into account an estimate of others’ reputations.
Revising and Improving the ITU-T Recommendation P.912
Authors: Leszczuk Mikołaj
Published: April 2024

It was once thought that high Quality of Service (QoS) performance solves recurrent problems of lowquality multimedia services. Since then, solutions have been proposed to ensure a high level of Quality of Experience (QoE). In this paper, the author attempts to outline an understanding of an accurate meaning of multimedia services quality. Starting from QoS and passing through generalized QoE, the author focuses on subjective aspects and objective quality modeling and optimization of visual performance for Target Recognition Video (TRV) applications (such as video surveillance), to outline the ITU-T standardization path in this area. The revising the ITU-T Recommendation P.912 is proposed to reflect improved subjective test techniques developed since this Recommendation was approved. Also at least some existing errors of reasoning are predicted, which are likely to become evident for the industry in the next decade. Finally, the author invites all researchers working on topics related to TRV to join him in the process of improving P.912.
Possibilities to Optimize QoS with Next SON Versions
Authors: Langer Małgorzata
Published: April 2024

The paper discusses quality of service in LTE and LTE-A networks seen as a challenge that can be met with SelfOrganizing Networks (SON) functionalities. The SON concepts have been included in the LTE (E-UTRAN) standards since the first release of the LTE technology. Self-optimization functionalities will monitor and analyze performance measurements, notifications, and self-test results and will automatically trigger re-configuration actions on the affected network nodes when necessary. The SON specifications have been built over the existing 3GPP network management architecture, the ultimate implementation of SON in 4G networks will bring many advantages. Successive SON procedures are waiting for their time and money to be implemented in 4G, though some essential issues for example of inter Radio Access Technology (RAT) interfaces must be overworked.

Published: April 2024

Filipinos consume root and tuber crops as inexpensive sources of nourishment. However,
the limited information on the nutritional and mineral bioavailability of root and tuber
crops inhibits their optimal utilization in what could possibly address nutrient deficiencies
among the populations. This study determined the proximate composition of cassava,
sweet potato, taro, giant swamp taro, cocoyam, and purple yam through the Association of
the Analytical Chemists (AOAC) standard method. The mineral bioavailability was
determined in vitro by simulating digestion from the oral up to the intestinal phase.
Mineral and trace metal contents were quantified using a Microwave Plasma Atomic
Emission Spectrometer (MP-AES). The crops’ ash, protein, fat, and total dietary fiber
contents ranged from 1.23-3.53%, 2.01-9.32%, 0.18-0.83%, and 4.23-19.3%, respectively.
Taro (9.32%) and purple yam (6.71%) have the highest protein contents among the crops
examined and can be considered as sources of protein based on the recommended nutrient
intake (RENI) for Filipino adults. Except for cassava, most of the studied crops were high
sources of total dietary fiber, with the giant swamp taro (48% RENI) as the highest. Total
minerals such as K, Ca, Mg, Na, and considerable quantities of Zn, Mn, Fe, and Cu were
detected. The mineral bioavailability varied for Zn (47.0-98.0%), Cu (37.5-86.8%), Mn
(31.5-91.8%), Mg (31.9-90.2%), Ca (2.54-31.1%) and Fe (4.7-20.7%). Consumption of
100 g of the examined crops, except for giant swamp taro and cassava, can contribute to
the daily Cu for adults aged 19-29. Taro contributes to the daily nutritional requirement
for bioavailable Ca and Mg, while giant swamp taro contributes to Zn and Mn
requirements. None of the examined crops contained sufficient bioavailable Fe to
contribute to Filipinos’ daily requirements. The study can help address the limited
information on the nutritional and mineral bioavailability of root and tuber crops, which
hampers their utilization to address some nutrient deficiency among the Filipino
population, and emphasizes the consumption of these crops to enhance dietary
diversification, which can alleviate some nutrient deficiencies in the country.

instant yellow rice
Authors: Anam C. , Rahmawati A.D. , Kawiji
Published: April 2024

Instant yellow rice is an alternative breakfast menu with a short serving time while
preserving traditional cuisine. Rice as the main ingredient of yellow rice is difficult to
replace and has little nutritional content. Making instant yellow rice using the autoclavingfreezing method requires fast drying to minimize nutrient degradation and maximize
rehydration time. The study used local tuber substitution of porang as a source of minerals
while increasing the nutritional content of instant yellow rice. This study aimed to
determine the effect of porang flour substitution and drying time on physical, chemical,
and sensory characteristics and to determine the best formula for instant yellow rice with
porang flour substitution. This study was conducted using the completely randomized
design (CRD) method with two factors, namely variations in the concentration of porang
flour (2%, 3% and 4%) and variations in drying time (5 hrs, 6 hrs and 7 hrs). The results
of the analysis showed that the concentration of porang flour and drying time showed a
significant effect (p<0.05) on the physical, chemical, and sensory characteristics of instant
yellow rice. Porang flour substitution and drying time significantly affected rehydration
time, expansion volume, moisture content, ash, protein, fat, carbohydrates, and panelists'
preference for color attributes. And it has no significant effect on the bulk density and
panelists' preferences on aroma, taste, texture, and overall. The best treatment was instant
yellow rice with 2% porang flour substitution and drying at 60℃ for 6 hrs. With a high
proximate nutritional content, good physical properties, and is well received by the
sensory panelists.
FLEXURAL BEHAVIOR OF BAMBOO REINFORCED FERROCEMENT PANELS
Authors: Mukta S. Bangar  , Dr. U. R. Kawade
Published: April 2024

Ferrocement is an emerging technology that differs from conventional reinforced concrete by the manner in which the reinforcing elements are dispersed and arranged. It consist of closely spaced, multiple layers of wire mesh embedded in cement mortar. Traditionally steel is used as reinforcement in concrete structures; but because of cost and availability, replacement of steel with some other suitable material as reinforcement is now a major concern. The construction industry is the main consumer of energy and materials in most of the countries. Since Bamboo is a natural, ecologically friendly, cheap and also readily available material; it can be use as a substitute of wire meshes in reinforcing of Ferrocement structures. This study describes the results of testing of Ferrocement beams reinforced with different number of Bamboo mesh layers and variation in spacing of bamboo reinforcement. The main objective of these experimental tests is to study the effect of using different numbers of Bamboo mesh layers and spacing variation on the Flexural strength of Ferrocement beams.

Unlike other minorities examined in this volume, the Arian one constituted a dominant minority in the Peninsula until the conversion of Reccared. While considering the Arian creed as an ethnic command, traditional historiography did not explore too much the religious component of domination. As much as the sources allow, this article studies the religious dimension proposed by this way of ordering society on two converging levels, which are Arianism as a parameter of hierarchy and Arianism as theology.
Escritura documental, zozobra e intersubjetividades en Había mucha neblina o humo o no sé qué, de Cristina Rivera Garza.
Authors: Estrada Orozco Luis Miguel
Published: April 2024

ABSTRACT: En Había mucha neblina o humo o no sé qué, Cristina Rivera Garza sigue al escritor Juan Rulfo en trabajos vinculados a la producción de la modernidad mexicana: la llantera Euzkadi y la Comisión del Papaloapan. Para Rivera, el Rulfo que escribe sobre mundos a los que su actividad laboral erosiona encarna la tensión entre la literatura y los discursos de construcción de nación del siglo XX. En este trabajo, propongo una lectura desde las ideas del filósofo mexicano Emilio Uranga. Algunas de las contradicciones que Rivera aborda en su visión de Rulfo encuentran una lectura novedosa en la zozobra del ser-para-el-accidente del mexicano de Uranga. Esta perspectiva también ayuda a comprender las relaciones intersubjetivas, fallidas en el mundo rulfiano, que el libro de Rivera vuelve productivas.
RESUMEN: In Había mucha neblina o humo o no sé qué, Cristina Rivera Garza follows Juan Rulfo working jobs related to the production of Mexican modernity: the tires company Euzkadi and the Papaloapan River Commission. According to Rivera Garza, Rulfo, as someone who writes about worlds eroded by his very jobs, embodies the tension between literature and the discourses of construction of the nation during the 20th century. In this article, I revise the book under three key concepts by Rivera Garza herself: de-appropriation, documentary writing and geological writing. Also, I propose a reading of Había mucha neblina… using the ideas of Mexican philosopher Emilio Uranga. Some contradictions Rivera sees in her Rulfo find a new reading through the “Zozobra” of the being-for-the-accident in Uranga’s view of Mexicanity. This view also helps understanding the intersubjective relationships, failed in Rulfo’s world, that Rivera’s book turns into productive ones.

The “Primitive” Cecilia Valdés. A short story by  Cirilio Villaverde. A translation and introduction by Thomas Genova
Authors: Genova Thomas
Published: April 2024

ABSTRACT: The text is the first English translation of Cirilo Villaverde’s 1839 “primitive” Cecilia Valdés, a short story that the author penned decades before publishing his canonical novel by the same name. The 1882 novel narrates the unwittingly incestuous relationship between the novel’s eponymous mulata heroine and her creole half-brother Leonardo Gamboa. Though the work enjoys high-canonical status, its textual history, tightly entangled with nineteenth-century Cuba’s racially fraught struggle for independence, is largely unknown to non-specialists. The translation is preceded by an introduction that discusses the short story’s relationship to the novel and the racial and political ideas present in the earlier text, as well as the translator’s efforts to render these paradigms legible to an English-language readership.

Published: April 2024

This article reviews the first-ever published materials from the archive of Taisia Iosifovna Yukhnevskaya, the late wife of Ivan Antonovich Efremov (1908–1972). The focus is on I.A. Efremov’s collection of autobiographical and erotic short novels titled “Women in My Life”. These fourteen stories (one of which is incomplete) are believed to have been written between the 1950s and 1960s. They fit perfectly with the style of the writer, for whom there was no division between the physical aspects of love and the spiritual development of a normal person. The short novels contain a wealth of personal details, thus offering a new and deeper perspective on the early years of the rising geologist and social thinker. In terms of fiction, they continue the 1940s series “Tales of the Extraordinary” and conform to the genre characteristics of romantic storytelling, as well as colonial and Western novels. There are clear similarities and plot parallels with I.A. Efremov’s other novels such as “Andromeda: A Space-Age Tale”, “The Bull’s Hour”, “Razor’s Edge”, and “Thais of Athens”. An interesting finding is that the letters between I.A. Efremov and his wife bring out an unforeseen side of the writer’s character, especially his ability to inject humor, which is a departure from his usual literary approach.
The Role of Metonymy in Shaping the Advertising Worldview (Based on the Appliance and Electronics Advertisements)
Authors: Gaynutdinova A. A.
Published: April 2024

This article explores the use of metonymy in advertising discourse through a detailed analysis of slogans in appliance and electronics advertisements. The influence of metonymy on one’s worldview in the context of commercial advertising was studied based on its contribution to the construction of the images of the object (product or service), subject (seller or manufacturer), and addressee (consumer), as well as to the development of connections between these three elements. The value and relevance of the research lie in the fact that advertising broadcasts ideas about reality and has the potential to influence the consumer’s mindset and behavior. This supports the concept of advertising worldview. It is also important to perceive metonymy as a linguistic and cognitive tool, yet in advertising discourse it is often viewed as a trope. The dynamics of the advertising situation can be defined as follows: the manufacturer/seller offers a solution to the consumer’s problems and promises them joy in the final result, with the product or service acting as a tool to achieve the desired outcome. A number of examples were provided to show that the knowledge about the components of the advertising situation is arranged in the categories of different conceptual structures which determine the type of metonymic transfer. In appliance advertisements, the most frequent metonymic models were found to be as follows: the product’s quality–the product, the result of using the product–the tool employed to achieve the result, describing the situation through the nomination of the stage of turning on the device or achieving the result. It was concluded that metonymy emphasizes the most important characteristics of the product and its role in human life, not only as a problem-solving tool but also as a source of positive emotions and joy, as well as a symbol of a certain lifestyle. Therefore, the metonymic approach is effective in fitting the product into the everyday life of the consumer with respect to their system of values.

Conclusion: It can be concluded that the incidence of GDM in Sleman is high, with characteristics of age at risk (≥35 years), history of previous illnesses and obesity.
Use of ICT to implement an active learning strategy in soil mechanics courses at undergraduate level
Authors: Macedo Joaquim , Oliveira Paulo
Published: April 2024

Nowadays engineers are constantly dealing with more complex problems, uncertainty, incomplete data, and demands of customers, governments, environmentalists, and public. This requires technical skills as well as skills in human relations. So, during their academic background it is necessary to incorporate more skills, social and technological, into their base knowledge. This can be accomplished introducing Information and Communication Technologies (ICT) in Higher Education (HE). Several studies show that the use of ICT in teaching promotes participation, engagement, collaboration, and student interaction, making them more active participants and responsible for their learning. In addition to these advantages, ICT allow to give equal importance to learning processes and to the contents, as the activities offered by ICT allow to the students develop communication skills, teamwork, finding and evaluating information, access, and manipulation of large amounts of data, work with other technologies, update and refine existing skills and knowledge. It was in this context that Guided Exercises emerged. A Guided Exercise permits students to relate models and help them to solve a complex exercise step by step. This strategy was used in two consecutive courses of an undergraduate degree in Civil Engineering, Soil Mechanics I and Soil Mechanics II at the University of Aveiro, Portugal. The results show that students considered the strategy useful for the understanding of the concepts covered in the course. Analysing the students’ academic performance, it can be concluded that those who used this methodology had a better approval ratio. This paper presents data to support these statements.

Published: April 2024

In this study, the surface coating (modification) of micronized calcite (CaCO3, d50=135 μm) in a stirred media (bead) mill with stearic acid was investigated. As a result of 15 min grinding and 5 min coating experiments, a product with d50=2.15 μm and specific surface area of 3.21 m2/cm3 was obtained. The activation rate of this final product as an indicator of coating rate was 97.7%. According to the optimum coating results, the stearic acid rate was determined as 1%, the modification time was 7.5 min, the ball load was 900 g and the stirring speed was 600 rpm.

Some experimental studies are carried out considering a longitudinal feature. In view of this, the classical regression models are not able to handle with it, since the independence assumption between the observations is violated. To handle with this kind of data it was proposed the called linear mixed-effects models, where it is possible to model the response variable taking into account the correlation between the observations, and even between the response variables, when there are two or more of them in study, setting a bivariate or multivariate scenario, respectively. For the diagnosis of the linear mixed-effects models the least confounded residuals are quite recommended due to their lower bias in relation to other types of residuals, but it is not so used in the literature. Using a data set of dairy calves’ performance according to three different diets over eight weeks, the linear mixed-effects models theory under univariate and bivariate approach was applied alongside the least confounded residuals in the diagnosis of the model for both approaches. Comparing the univariate and bivariate approaches, the last one was more informative presenting lower standard errors’ values for its estimates, while the least confounded residuals was more efficient than the classical residuals present in the literature.

Monitoring sugarcane areas through remote sensing is essential for planning and management of the national sugarcane industry. The use of machine learning algorithms has provided many benefits to remote sensing. This article aims to compare the prediction quality of three important machine learning methods in identifying sugarcane areas using Landsat images: Logistic Regression (LR), Decision Tree (DT) and RandomForest (RF). LR was applied in three versions: LR without penalization, LR with Ridge penalization (LR-R) and LR with Lasso penalization (LR-L). Data obtained in this study refer to a region of approximately 306,000 ha located in the state of São Paulo, Brazil, which was segmented into approximately 46,000 polygons (observations). Six spectral bands and vegetation indices observed along 17 months resulted in 102 covariates, which were reduced via Principal Component Analysis (PCA). In total, 19 Principal Components were chosen to account for 94.61% of the cumulative explained variance ratio and were used in machine learning methods to classify each polygon as sugarcane or other land covers. The method with the highest accuracy considering testing sample of 20% of data was RF (78.51%), followed by DT (72.30%), LR-L (69.64%), LR-R (69.64%), and LR (69.52%).
