Building an Autonomous Portable Device to Analyse Wireless Traffic Protocols in IoT
Authors: Alvarez-Sánchez José Á. , Pérez-Jove Rubén , Vázquez-Naya José Manuel
Published: February 2023

Monitoring wireless traffic of Internet of Things (IoT) devices can be interesting for multiple reasons, such as carrying out security audits, assisting in debugging tasks or even checking the correct state of the inventory to detect obsolete or unused equipment.

There are currently several tools available on the market that undertake this sort of functionalities, allowing devices that use these protocols to be debugged or the traffic they emit to be analysed. Some examples of this type of solutions are Ubertooth or CC2531. However, these solutions require human intervention or connection to some other hardware such as a laptop.

In this project, we developed a tool that can analyse Wi-Fi, Bluetooth and ZigBee pro- tocols due to their increased use in IoT environments. Unlike most of the equipment avail- able on the market, the proposed tool can work with multiple protocols and autonomously, including its own storage system and energy supply.

Authors: Gende Mateo , Moura Joaquim de , Novo Jorge , González Penedo Manuel F. , Ortega Marcos
Published: February 2023

The Epiretinal Membrane (ERM) is an ocular pathology that causes visual distortion. In order to detect and treat the ERM, ophthalmologists visually inspect Optical Coherence Tomography (OCT) images.This is a costly and subjective process. In this work, we present three different fully automatic, end-to-end approaches that make use of multi-task learning to simultaneously screen for and segment ERM symptoms in OCT images. These approaches were implemented into three architectures that capitalise on the way the models share a single architecture for the two complementary tasks.
Family Araliaceae in Southern Africa: A Review of Ethnobotanical Uses, Phytochemistry, Pharmacology, and Toxicology
Authors: Maroyi Alfred
Published: February 2023

There is widespread use of species belonging to family Araliaceae in traditional medicine in southern Africa. The aim of this review was to assess medicinal uses, phytochemistry, pharmacology and toxicological properties of indigenous species belonging to family Araliaceae in southern Africa. Relevant articles, books, theses, dissertations, patents, and other English-only reports on the medicinal uses, phytochemistry, pharmacological and toxicological properties of species belonging to the family Araliaceae in southern Africa (Angola, Botswana, Eswatini, Lesotho, Malawi, Mozambique, Namibia, South Africa, Zambia and Zimbabwe) were reviewed. Databases such as PubMed, Web of Science, Elsevier, Google Scholar, Scopus, Springer, Science Direct, Taylor and Francis between January and July 2022. Eleven species, namely Cussonia. arborea, C. arenicola, C. natalensis, C. nicholsonii, C. paniculata, C. sphaerocephala, C. spicata, C. transvaalensis, C. thyrsiflora, C. zuluensis and Neocussonia umbellifera are used as traditional medicines against 48 human and animal diseases. This study showed that alkaloids, anthocyanins, anthracene glycosides, botulin, flavonoids, free gallic acid, iridoids, phenolics, saponins, steroids, tannins, triterpenoids and volatile oils have been identified from these species. Pharmacological research revealed that the crude extracts and compounds demonstrated isolated from these species are characterized by Aβ42 protein reduction, acetylcholinesterase, analgesic, antibacterial, antifungal, antiviral, anticancer, antihyperglycemic, anti-inflammatory, antileishmanial, antioxidant, antiplasmodial, antiprotozoal, anti-ulcer, immunomodulatory, larvicidal, molluscicidal, spermicidal, cytotoxicity and toxicity activities. Reports of medicinal uses, phytochemistry, pharmacology and toxicological properties of species belonging to the family Araliaceae in southern Africa could only be found for 11 species, suggesting that further investigation of largely unexplored family members is necessary.

Published: February 2023

This study aimed to estimate the protective effect of a combination of S-Adenosyl-L-methionine (SAM) as a precursor of glutathione and oseltamivir as a specific inhibitor of virus replication on oxidative damages caused by influenza infection in the liver of infected mice. Albino mice were inoculated with 10×LD50 of influenza virus A/Aichi/2/68(H3N2). Oseltamivir was applied for five days after infection, twice per day, in a dose of 2.5 mg/kg. SAM was applied for ten days in a 100 mg/kg dose, starting five days before inoculation. Markers of oxidative stress, mortality rate, mean survival time, index, and protection coefficient were followed. Influenza infection causes severe oxidative damage to the liver. All combinations of SAM and oseltamivir restored the levels of the biochemical markers to those in healthy animals and improved the virological parameters. A combination of SAM 100 mg/kg and oseltamivir 2.5 mg/kg, which is 1/4 of the optimal therapeutic mice dose, exhibits protection index and affects most effectively all the tested parameters. This study provides an easy-to-apply approach with a good therapeutic potential for co-medicating influenza infection with a specific antiviral agent and an antioxidant precursor.
Glycine Betaine
Authors: Singh Amantika , Singh Pooja , Choudhary Krishna Kumar
Published: February 2023

Abiotic stresses like temperature, water, salinity, ultraviolet (UV) radiations, heavy metals, etc., affect plants’ growth and yield. Despite these constraints, plants produce a variety of metabolites to maintain their survival. Primary metabolites, produced through crucial metabolic processes, are essential for plants survival. Additionally, secondary metabolites (SMs) are synthesized from primary metabolites and are mainly used as a defensive mechanism and a means of interacting with unfavorable environmental conditions. In addition to their defensive function in plants, SMs are significant in the pharmaceutical industry. Glycine betaine (GB) is a quaternary ammonium compound that belongs to a class of SMs, present in plants, animals, and microbes. It functions as a compatible solute and reflects potential bioactivity against various abiotic stresses like salinity, water, heat, heavy metals, UV radiations, etc. Due to high solubility and low viscosity, its accumulation is commonly observed in chloroplasts and plastids. The accumulation level generally depends on plant species, growth stage, exposure duration, and stress's nature. GB reduces oxidative stress and prevents the damaging of photosystems and other biomolecules under stressful conditions. It is important for maintaining the water potential and osmotic pressure of cells and hence functions as a potent osmolyte under salinity stress. Excessive production of ROS during temperature stress is responsible for damage to oxygen-evolving complexes, electron transport chains, and photosystems. In order to protect plants from these damages, GB activates the genes responsible for synthesizing heat shock proteins, glycoproteins, and antioxidants via various signaling pathways. GB alleviates the effect of water stress by maintaining the function of rubisco and calcium ion ATPase activity via crosstalk with Abscisic acid (ABA) and ethylene. GB supports the proper functioning of the ascorbate-glutathione cycle, superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase (antioxidative enzymes) to overcome various stresses. Phytohormones like salicylic acid (SA), jasmonic acid (JA), ABA, ethylene, and polyamines (PAS) coordinate well with GB via different signaling pathways to ensure plant protection under various abiotic stresses. The potential bioactivity of GB against various abiotic stresses in plants has been summarized in this review.

Between the Craft and the Mud: An Analysis of the Work and Health Relationship of Firefighters in the Breach of the Córrego do Feijão Dam—Brumadinho/MG
Authors: Santos Hugo , Oliveira Simone , Portella Sergio
Published: February 2023

Faced with the rupture of the VALE S.A. tailings dam that hit the city of Brumadinho (MG), the article sought to better understand the organisation of work of military firefighters who participated in the search and rescue operation and the relationship between work and health present in this scenario. This is a qualitative research with a focus on the subjective production of the speeches of seven firefighters who were interviewed individually with a semi-structured script, using as a basis of analysis the ergological perspective and the productions of the psychodynamics of work. The firefighters experienced a scenario with risks of injury, contamination, and even death. In the interviews, they showed that more than twelve hours of work was responsible for sleep problems during and after the performance, as well as the food provided and the lack of time for physical exercise proved to be aggravating factors for their health. Working in the tailing’s mud combined the development of musculoskeletal problems and anxiety, due to the possibility of contamination by metals present in the mud. The work relationships show a high degree of trust and recognition between the firefighters and the affected population, which helped in the motivation and continuation of the operation until the present moment. The work in this operation that gained national prominence was responsible for the feeling of pride and for feeling more capable and prepared to act in other disasters. This research is expected to broaden the discussion about the work-health relationship of military firefighters exposed to disasters, as well as serve as a subsidy to encourage the creation of public policies focused on the health of these workers.

Authors: Furo Orupabo  , Boma Oyan  , Sarah Abere
Published: February 2023

Introduction: Low back pain is common in health workers with deleterious effects on their work and quality of life. Aims: This study aimed to identify work related disabilities and risk factors for low back pain amongst doctors in Nigeria. Methodology: One hundred and fifty-four doctors were recruited and a structured proforma was administered using the Aberdeen low back pain scale, revised Oswestry and Quebec pain scales as guides. Data was analysed using Statistical Package for the Social sciences version 25. Univariate and multivariable logistic regression were used to calculate the odds ratios for the independent risk factors for LBP. Level of significance was determined at p < 0.05. Results: The male to female ratio was 1.8:1 and 70(45.50%) doctors were in the age range of 31-40years. Half (50%) of the respondents were obese while 21.9% were overweight. The duration of an episode of back pain was less than a week in 130 (84.40%) persons. A few doctors- 22(14.29%) reported that low back pain had prevented them from coming into work, of these, 12 had been absent for a day, four for 2-7 days and six for 1 to 4 weeks. Anesthetists were ten times more likely to develop low back pain than any other medical specialty (OR=10.99, 95%CI=1.336-90.545, p=0.026) and increasing age and BMI were also identified as predictors of low back pain. Conclusion: Low back pain is associated with poor productivity among doctors and can impact health care delivery.

Authors: Kubugha Wilcox Bunonyo  , Liberty Ebiwareme  , Paul Ziakede Awomi
Published: February 2023

In this paper, we explain the effect of temperature on the distribution of drugs between the stomach and the bloodstream compartments of the human body. The study demonstrates that the behavior of drug distribution is linked with high or low surrounding temperatures in the compartments (the stomach and bloodstream) under study. In the study, we converted real-world problems into mathematical equations and then solved the resulting remodeled system and the mathematical models found in previous research by introducing a temperature component in an attempt to understand the behavior of a drug administered in the human body over time. The analytical solutions for the drug concentration in the stomach and bloodstream were obtained using separation of variables and variation of parameters techniques of solving ODEs, while the numerical solutions and the graphical results were obtained using Wolfram Mathematica. The results show that as the temperature rises, the drug administered into the system diffuses faster between the compartments and diffuses slower as the temperature falls, which shows the novelty of this research project.

Abstract

In the pandemic era, online learning activities require students to become independent learners. Several factors that influence learning independently are curiosity and motivation to learn. This study aims to see the effect of 1) learners' curiosity and motivation on independent learning, 2) learners' curiosity on independent learning, and 3) learners' motivation on independent learning. The samples of this research include 45 students of Mathematics Education. Questionnaires were to collect the data. The data obtained were analyzed by using multiple linear regression analysis. The results indicate that curiosity and learning motivation have a positive effect on independent learning. The relationship between curiosity and learning motivation with independent learning is in a strong category. The effect of curiosity and learning motivation on self-regulated learning is 41.4%, while 58.6% is determined by other variables which were not examined. However, curiosity does not affect student independent learning, while learning motivation affects independent learning. Thus, curiosity must be accompanied by learning motivation so that students can become independent learners. The provision of learning that increases students' curiosity must be accompanied by the provision of motivation to increase students' independent learning.

Published: February 2023

Tolerance in the sense of brotherhood refers to respect and acceptance of one another. Islam is a belief revealed by Allah through His Messenger Muhammad SAW as a mercy to the universe, rahmatan lil 'alamin, and applies to all humans on earth as a moral guide for humans both in the East and in the West. Nevertheless, despite the fact that there are many other religions that individuals profess today, these widely held beliefs continue to acknowledge and respect each other's existence and the fact that Allah has honestly given everyone the freedom to follow any religion. . which they choose. The main principle of Islam is to provide a calm and pleasant atmosphere for human existence as a blessing for the existence of the universe. Freedom of religion, according to the Qur'an, is the absence of deficiency in practicing one's religion and the inability to coerce non-Muslims into Islam. Both Muslims and non-Muslims can propagate their own religion both within and outside their own social circle, and defend it from criticism or harm.

Published: February 2023

The global expansion in the Internet access and the rise of digital media are compatible with students’ characteristics as generations-Z who mainly engage in nature through mobile applications. Because of the characteristics of today’s students and the growth of digital media and information, there is a need for critical media literacy (CML) instructions and the use of digital-based and student-centered learning approaches such as online discussion forums (ODFs). Through an exploratory study, we aim to understand better students’ perceptions of ODF for their CML learning within EFL classes, factors affecting students’ active participation in ODF, and teachers’ roles in ODF while facilitating students’ CML learning in an EFL context and enhancing students’ engagement and performance in ODF. 250 EFL students from Indonesian secondary schools took part in this study.

Published: February 2023

Concentrated platelet components are the components or platelets that are processed through centrifugation from whole blood or a single donor. The components of the concentrate platelets are stored in an agitator at a temperature of 20-24◦C with a maximum shelf-life of five days. During the storage, a change in component metabolism occurs, which is characterized by alteration in platelet morphology as an indicator of decreasing quality of platelet components. The purpose of this study was to determine the quality of the components of platelets based on the shelf-life by measuring the platelet morphological values with the Kunicki method. This study applied an experimental method by conducting inspections of the regional blood transfusion unit (UTDD) of the Indonesian Red Cross of  Jakarta Capital Special Region (PMI DKI Jakarta). Platelet morphological values of six components of platelets were examined by the Kunicki method on day 0 to day 5 of shelf-life. Quality assessment was carried out based on a significant difference-dependent t-test and comparison with normal value. The results of the study by performing statistical analysis of the significant difference-dependent t-test showed a significant difference of values between day 0 and day 1 to day 5 of shelf-life. Comparison with normal values ​​depicted that all samples stored on day 4 had a morphological value of more than 200. On day 5 of shelf-life, the platelet morphology values ​​of five samples were below 200. The quality of the concentrated platelet components is said “good” if it is above 200. This study concluded that there was a significant difference in the platelet morphology values between the components of concentrated platelets on day 0 and day 1 to day 5 of shelf-life. All samples were of good quality until day 4 of storage. However, on day 5 of storage, only one sample was good in quality.

The host susceptibility mechanisms such as Vitamin D Receptor (VDR) is involved in the modulation of macrophage function and may possibly correlate with immunity disease including the severity of typhoid fever symptoms. The study aimed to assess the VDR Protein expression in the serums of recurrent acute typhoid fever (RATF) patients and compares it with typhoid fever (TF) patients, and healthy persons (HP). The study employed 30 RATF patients and 30 TF patients selected from primary health centres and hospitals in Eastern Indonesia as the endemic area. All the samples were obtained from several health centers in South Sulawesi, Southeast Sulawesi, Central Sulawesi, East Kalimantan and Papua and then collected in the sample bank  Biology Laboratory of Molecular Immunology, Faculty of Medicine, Hasanuddin University. As a comparison, 30 samples of healthy persons were also selected from the Blood Transfusion Unit in Makassar, South Sulwesi Indonesia. The profile of VDR Protein was analyzed with Enzyme-linked Immunosorbent Assay (ELISA). VDR protein content data on RATF and TF were designed according to completely randomized design T test. Subsequently, it correlated to Pearson correlation to determine the interaction between Widal titre and VDR protein levels. A comparison between Widal titre and VDR Protein level was also made to identify the correlation. It was found that the mean of VDR protein expression of RATF was 13,44 ng/mL, the mean of VDR protein expression of TF was 24,88 ng/mL, and the mean of VDR protein expression of HP was 43,49 ng/mL. The correlation results between RATF-TF Widal titre and VDR protein level indicated a negative correlation with p-value of 0,004. There were significant differences in the VDR expression in the RATF, TF, and HP. RATF VDR expression lower than TF and HP and there was also a correlation between Widal titre with VDR Protein expression.

Coffee provides a genuine source of caffeine. Caffeine can have a variety of pharmacological effects on both central and peripheral nervous systems and most of these effects are related to the antagonistic mechanism at adenosine receptors. The most prominent effect of caffeine remains stimulation of brain function, improving mood and physical performance. Robusta coffee obtains an intense level of caffeine and Pagar Alam City is one of the cities in Indonesia that produces robusta coffees. This study aims to identify and characterize caffeine isolated from Pagar Alam robusta coffee beans using thin-layer chromatography methods, UV-Visible spectrophotometry and to determine caffeine levels in wistar rat blood using the ELISA method. This method is cost-effective, familiar to perform and has a considerable degree of accuracy and reproducibility. The isolated samples have similar characteristics to standard caffeine with an Rf value of 0.77, a maximum wavelength at 273 nm with the absorbance of 1.3 and from caffeine profile in the blood sample we obtained the maximum sample concentration in blood 0.582 ± 0.249 μg/ml and the time needed to reach the maximum concentration is 30 minutes.

Published: February 2023

The curation of seismic data sets is the cornerstone of seismological research and the starting point of machine-learning applications in seismology. We present a 21-year-long AI-ready data set of diverse seismic event parameters, instrumentation metadata, and waveforms, as curated by the Pacific Northwest Seismic Network and ourselves. We describe the earthquake catalog and the temporal evolution of the data attributes (e.g., event magnitude type, channel type, waveform polarity, and signal-to-noise ratio, phase picks) as the network earthquake monitoring system evolved through time. We propose this AI-ready data set as a new open-source benchmark data set.
