Authors: Qomariyah Laila Nurul , Kusumo Djati Wulan , Pratiwi Elasari Dwi
Published: February 2024

Background: In 2023, Dengue Fever cases in Indonesia reached 35,694 cases from January to May. Dengue Fever is caused by the bite of Aedes aegypti mosquitoes. Mosquito control efforts have been widely conducted, including the use of chemical insecticides. The use of chemical insecticides can lead to environmental contamination and cause skin irritation. An alternative approach that can be taken is to use natural insecticides. One of the natural insecticides that can be used as a repellent is citronella and basil essential oils. Citronella and basil essential oils contain geraniol and citronellal, which can cause mortality in mosquitoes. This study intends to evaluate the effectiveness of a spray mixture of basil leaves and citronella essential oil as a mosquito repellent. Materials and Methods: Aedes aegypti mosquitoes, basil leaf essential oil, citronella essential oil, propylene glycol, glycerin, butylated hydroxytoluena and etanol 96% v/v. Subsequently, an evaluation of physical properties was conducted, including organoleptic testing, pH, and viscosity evaluation, as well as irritation and repellent activity test. Results: The spray formulations in the control and F1 are clear in color, while F2 and F3 are clear with a slightly yellowish hue. The scent produced has the characteristic smell of citronella. The pH and viscosity tests resulted in pH values consistent with the skin's pH range of 4.5-7 and viscosity within the range of 1-1000 Cp. The spray formulation did not irritate after 48 hours of observation. The results of the effectiveness test indicate that F2 can protect against mosquito bites for 1 hour, while F3 can protect for 3 hours. Conclusion: Citronella essential oil and basil leaves are effective as a repellent for the Aedes aegypti mosquito for 3 hours of use in concentration 15%.

Authors: Montes Luz Amanda , Gómez Pachón Edwin Yesid , Sánchez Cepeda Angela Patricia , Pineda Triana Yaneth
Published: February 2024

Water contamination by heavy metal ions is a current problem that affects human health and occurs mainly due to anthropogenic activities. One of the main mechanisms for water decontamination is the use of magnetic adsorbent materials, because it is a method of easy implementation, low cost and easy recovery, with the use of an external magnetic field. In this study, an electrospun polymeric membrane of PVDF-PS with magnetite (Fe3O4) nanoparticles was successfully fabricated. The morphological characterization of the membrane with SEM showed that the fibers reach a diameter of around 2.5 µm, increasing the contact surface area for the adsorption of heavy metal ions. The magnetic nature of the electrospun membrane is calculated with a vibrating sample magnetometer (VSM), which shows that the material is superparamagnetic in nature due to the incorporation of magnetite nanoparticles. These characteristics of adsorbent materials are relevant for potential use in heavy metal adsorption processes.

Authors: Suárez Gómez Andrés David , Bareño Quintero Jorge Orlando
Published: February 2024

In the context of the rapid progress in the field of mobile robotics, the need for efficient systems with high embedded processing power has emerged as a fundamental challenge. This paper addresses this issue by using FPGAs, devices underutilized in the literature for the development of architectures with H/S (hardware/software) co-design in mobile robots. The suitability of FPGAs for this purpose is highlighted, as they offer a balance between efficiency and low power consumption. The paper focuses on the implementation of a SoPC (System on Programmable Chip) based architecture designed specifically for an FPGA-based differential drive mobile robot. The most relevant aspects of the design are presented by means of diagrams illustrating the layout and interconnection of key components. The practical implementation of this architecture was carried out on a mobile robot whose processing unit is a DE0 Nano development board equipped with a Cyclone® IV FPGA. The results obtained reveal a successful behavior of the architecture in terms of interfacing with sensors, actuators, and data processing. The efficiency of the design is reflected in the balanced occupation of resources in the FPGA, highlighting the 67% of logical area still available for future implementations of modules for hardware acceleration. This paper demonstrates the feasibility and efficiency of FPGAs in the design of advanced architectures for mobile robots, providing a solid foundation for future research and development in the field of robotics.

Published: February 2024

In the context of virtual and distance education, the course "Introduction to Telecommunications Engineering" at the National Open and Distance University (UNAD) has faced the challenge of student attrition at first enrolment. To address this problem, a research study was carried out to develop a Data Mining model based on the CRISP-DM methodology. The study used a dataset with 808 student records collected in different academic periods of the year 2021. Several Machine Learning techniques were applied, such as Random Forest, Tree Decision, Knn, SVM and Neural Network, evaluating their performance through k-10 cross-validation. The results revealed that the Random Forest model obtained the best performance, predicting with 80% accuracy the passing rate of the course. This model is relevant for identifying students at risk of dropping out of the course early, allowing the implementation of proactive strategies to address dropout and improve course indicators. Although some results were slightly lower than previous research, the model remains a valuable tool to support student retention strategies in the "Introduction to Telecommunications Engineering" course at UNAD.
Measuring Accountable Information in CSR Reports: A New Operationalization and Analysis Applied to Greenhouse Gas Disclosures
Authors: Huq Asif M. , Carling Kenneth
Published: February 2024

We develop a novel and generic text-based measure to classify and evaluate greenhouse gas (GHG) disclosures. We construct the measure using collocation analysis of GHG-related words and regular expressions. Automated implementation achieved high concordance compared to manual investigations. We move beyond the “bag-of-words” approach in classifying voluminous nonfinancial corporate disclosure. We also outline a methodology that is manyfold scalable and makes replicability straightforward. Compared to past studies, we work with a significantly larger sample of 5,017 reports across 80 countries, thereby dealing with greater complexity and leading to better generalizability. We also contribute to the debate on whether nonfinancial disclosures exhibit accountability or are merely greenwashing. We find a negative trend in accountability worldwide, and firm-level accountability in GHG disclosures is not detectable in a country-level reduction of GHG emissions. Moreover, firms disclose significantly higher accountable information in a civil-law legal environment compared to those in a common-law legal environment.

Authors: Yudhanta Widi Cahya , Hadinata Irwan Yudha
Published: February 2024

The current development of information technology infrastructure has positively impacted the ease with which people can carry out work activities physically and creatively. Artificial intelligence, which is currently starting to penetrate the world of visual design and architecture, is starting to develop from integrating design methods to methods of presenting or communicating architecture. In this study, aspects of artificial intelligence are used as a pre-design method, which is considered to help speed up decisions in design communication. The problem raised in this study is how optimal the involvement of computing and artificial intelligence is in providing pre-design considerations in the case of simple residential houses, especially in the analysis, space, and visual aspects. This study aims to obtain the methods and influence of computing and artificial intelligence in formulating pre-designs and generating understanding regarding the methods of their use. Several analysis tools are used for the spatial approach: the space syntax using DepthmapX software, solar analysis using the Shadedat plugin, and the visual shape of the building using Stable Diffusion. This research uses an experimental approach to obtain the desired design results. This study's findings explain that applying appropriate computational and artificial intelligence methods will produce an effective and efficient design process. With the correct sequence, it will have a measurable design process that can be assessed well.
A Rare Case of Recurrent Dasatinib-Induced Chylothorax Years After Initial Treatment
Authors: Shaw Brian , Mubarak Norah , Nuaimi Mustafa , Persall Cosette , Vollenweider Thomas , Shaw Ryan , Madruga Mario , Carlan Steve J.
Published: February 2024

Background: Chronic myeloid leukemia (CML) is characterized by the Philadelphia chromosome containing the BCR-ABL protein with deregulated tyrosine kinase activity. Tyrosine kinase inhibitors (TKIs) were developed to target this oncogene. Dasatinib, a TKI, has rarely been associated with spontaneous chylothorax. The majority occur within 1 year of dasatinib initiation and resolve after drug cessation. In contrast, we present a patient with CML on dasatinib therapy for 8 years who developed recurrent unilateral chylothorax even after cessation of dasatinib.
Case: A 57-year-old male with a history of CML on dasatinib therapy presented to the hospital for nausea and vomiting. A computed tomographic scan revealed a large right-sided pleural effusion with thoracentesis yielding 1.5 liters of chylous fluid. The patient’s hospital course was complicated by intracranial hemorrhage and subsequent admission to the intensive care unit. Dasatinib was stopped during this time. The patient experienced multiple recurrences of this effusion with significant output via thoracentesis and chest tube despite dietary changes. Lymphangiography was performed but revealed no evidence of thoracic duct leakage.
Conclusions: Chylothorax from dasatinib is rare, usually occurs within 1 to 2 years of treatment onset, and resolves with discontinuation. However as supported by this case and others, it may occur as late as 8 years from treatment onset and chylothorax may continually re-accumulate or persist up to 1 year from dasatinib cessation. It is imperative to rule out underlying thoracic duct disruption prior to attributing etiology to dasatinib as a misdiagnosis may result in treatment delays.

Published: February 2024

We describe the characteristic macro- and microscopic findings of a new case of spontaneous fibroadenoma in a 21-week-old, non-treated female Wistar rat. A mobile and non-ulcerated mass was detected affecting the caudal inguinal mammary gland. At necropsy, the mass was 5.5 cm in size, spherical in shape, and well demarcated with a smooth surface. The cut surface was pink, with a multilobulated pattern. Microscopically, fibroadenoma was composed of dense connective tissue surrounding luminal epithelial tissue, organized in tubular structures. The luminal epithelial cells were typical and, in some areas, presented lipid vacuoles in the cytoplasm and proteinaceous material in the lumen of the tubules. The interlobular and intralobular stroma showed variable amounts of mast cells. Immunohistochemically, epithelial cells expressed both oestrogen and progesterone receptors in the nucleus. Fibroadenoma is a frequent tumour, but it is uncommon at an early age.

Published: February 2024

The potential of memristive biosensors as an effective and dynamic link between engineering and biology, providing direct and functional communication for extracting information about biological processes in the human body, is discussed. Memristors can be part of a processing chain and, in the future, combine signal conversion with subsequent processing, acting as intelligent sensors. An energy-informational memristor model describing this nonlinear physical and technical effect and a parametric block diagram for describing such nonlinearity are proposed. To obtain a model of the nonlinear physico-technical effect of a memristor within the framework of the energy-informational model of circuits, a special functional dependence in the “charge-pulse” plane was revealed. It is noted that the memristive effect is observed not only in electrical circuits, but is also described for mechanical, thermal, diffusion, and optical circuits, which are well represented in terms of an energy-informational circuit model. The presented model of the memristive effect will expand the knowledge base of the computer-aided design system by including passports of memristive physical and technical effects. A classification of biosensors based on memristive effects is proposed, which will make it possible to supplement the knowledge bases of the computer-aided design system with passports of memristive physical and technical effects in accordance with this classification and parametric structural schemes of memristive physical and technical effects. The systematization of knowledge based on the identification of the characteristics and features of biosensors, as well as the classification of various types of memristors, will automate the process of choosing the most appropriate type of memristor, taking into account the required characteristics and features of the biosensor, which will lead to an increase in the efficiency of synthesis of new designs of memristive biosensors.

Published: February 2024

In recent years, artificial intelligence technologies have demonstrated significant success in solving the problem of traffic analysis and forecasting in various telecommunication systems. Forecasting allows the telecom operator to know about the future behavior of the network, take timely necessary measures to improve the quality of customer service, and decide on the need to install or upgrade equipment. Using data collected from IoT mobile devices as an example, this article provides an overview and analysis of various time series forecasting models describing the traffic behavior of telecommunication systems. Forecasting models such as the exponential smoothing method, linear regression, the autoregressive integrated moving average (ARIMA) method, the support vector machine regression method, the N-BEATS method, which uses fully connected layers of a neural network for forecasting a one-dimensional time series, are discussed; the features of some of them are briefly outlined. For a specific data array, data preparation operations are described: removing unused columns, replacing missing data on transaction durations with their median values, and describing the main statistical characteristics of the data array. A preliminary data analysis is presented, which consists of using smoothing methods: moving average and exponential smoothing. The process of training models and a comparative analysis of the quality of their training are described. For this data set, it was concluded that for the UDP protocol the ARIMA model has the best learning quality, for the TCP protocol - linear regression and the Theta model, for the HTTPS protocol – linear regression, ARIMA and N-BEATS.
A risk-oriented ontological model for supporting management decision-making in a cargo port based on multi-level goal setting
Authors: Bondareva Irina Olegovna , Belova Anastasia Olegovna
Published: February 2024

In today's unstable market environment, transport logistics enterprises face the task of predicting possible risk situations in order to avoid them, as well as developing tools that allow them to form management decisions, evaluate the effectiveness of each of them and choose the most appropriate one, taking into account specific tasks and various influencing factors. Situations of failure to achieve the goals of a cargo port, as well as cases of failure by indicators to assess these goals of normative values, are considered as risks. The goals and indicators are outlined and described in the previously built Balanced Scorecard (MTSP). A set of links between goals and indicators of their assessment with risks at various levels of management is presented in the form of a developed multi-level hybrid logical-probabilistic (LV) risk model of a cargo port, as well as in detailed scenario models of this LV model. The integrated use of SSP and LV modeling technologies allowed us to build a general concept of multi-level goal setting, the main advantage of which lies in the detailed elaboration of the company's goals subordinate to the main strategic one, which allows, if necessary, to influence operational events and obtain a positive result in the longer term, in tactical and strategic plans. The ontological model contains all the information about the interaction of elements that affect the occurrence of risky events, and allows you to select options for getting out of a risky situation in accordance with various specified conditions. The results of queries to the risk-oriented ontological model are variants of management decisions aimed at reducing risks in the cargo port.

Complementary description of two Anthoseius De Leon (Acari: Phytoseiidae) species based on their holotypes with new synonyms
Authors: Döker Ismail , Atchia Isabelle , Jose Anna , Bolton Samuel J.
Published: February 2024

Due to the inadequacy of prior descriptions and the absence of redescriptions, studies on the taxonomy of the subgenus Anthoseius De Leon (Acari: Phytoseiidae) have become challenging and often cause confusion among taxonomists. Typhlodromus (Anthoseius) ghanii (Muma) and T. (A.) loralaiana (Muma) were described from Pakistan almost sixty years ago. Their original descriptions are not very detailed, being based on simple drawings and an absence of diagnostic characters that include measurements of dorsal setae. Most likely due to its inadequate description, T. (A.) ghanii was not recognized by acarologists and was therefore repeatedly described as a new species under different names. We examined the holotypes of T. (A.) homalii Gupta and T. (A.) sagaricus Karmakar et al. concluding both species to be junior synonyms of T. (A.) ghanii. Moreover, T. (A.) kuznetsovi (Denmark and Welbourn), described from Tajikistan, is proposed as a new junior synonym of T. (A.) loralaiana based on the examination of their holotypes. Hence, complementary descriptions of T. (A.) ghanii and T. (A.) loralaiana, based on their holotypes, are provided to facilitate species identification and to improve their diagnosis.

Published: February 2024

People with autism show identifiable impediments in three central aspects, namely communication, social interaction, and repetitive and restrictive behavior, which is called the triad of impairments. The communication observation of children with autism is relatively complex, so a specific procedure to identify their communication is required. A specific identification procedures on children’s communication aspect facilitate teachers and parents to provide an optimum alternative program for children with autism. This study aims to identify and develop an identification matrix focusing on the communication aspects of children with autism. This study used development methods and a qualitative approach. For the data validity test, we used data triangulation through interviews with experts. The results of this study are the development of a communication identification matrix as an approach on early detection on autism symptom. Despite the development of the identification matrix related to communication aspects, it is recommended to identify aspects related to social interaction and repetitive and restrictive behaviors according to the triad of impairment. As a highlight, early detection or screening cannot directly label that a child has autism, but early detection can be the first step to identify any developmental issues, and parents can refer the child to a psychologist or doctor for a clinical diagnosis.

Published: February 2024

Introduction

Gallibacterium anatis is an opportunistic bacteria inducing a range of clinical signs in poultry. Gallibacterium anatis strains show multidrug resistance to antibacterial substances. The purpose of this study was to examine the susceptibility of G. anatis biovar haemolytica isolates collected from the respiratory, reproduction and gastrointestinal tracts of chickens to different antibiotics from various classes.

Material and Methods

Gallibacterium anatis biovar haemolytica was identified in tracheal swab and gastrointestinal and reproductive tract tissue samples from Polish layer and broiler chicken flocks. Twenty six isolates with β-haemolysis capability, each from a different flock, obtained from the respiratory (n = 8), reproductive (n = 10) and gastrointestinal (n = 8) tracts were selected and identified by matrix-assisted laser desorption/ionisation–time-of-flight mass spectrometry after culturing. A PCR method targeting the 16S genes was used for verification of isolates. The isolates’ susceptibility to 20 antimicrobials was evaluated using the disc diffusion method for 8 drugs and the dilution method for the other 12. In addition, they were tested for the presence of the GtxA, gyrB and flfA virulence genes and blaROB, aphA, tetB and tetH antibiotic resistance genes by PCR.

Results

The most prevalent antibiotic resistance was to tilmicosin, tylosin and quinupristin/dalfopristin (all 100%), erythromycin (96.2%), tetracycline (96.2%), linezolid (92.3%) and teicoplanin (92.3%). Universal susceptibility was to only one antibiotic, chloramphenicol. Statistically significant differences were found between the resistance of gastrointestinal tract strains and that of strains from other tracts to daptomycin, gentamicin, ciprofloxacin and colistin. The GtxA and gyrB genes were detected in 100% of isolates and flfA in 19.2%. The isolates most frequently contained tetB and less frequently tetH and aphA, and did not contain blaROB.

Conclusion

Most G. anatis biovar haemolytica isolates were resistant to many classes of antibiotics. Therefore, it is necessary and important to be vigilant for the occurrence of these bacteria and thorough in their diagnosis.

Hyperhidrosis: problems and solutions
Authors: Petrova Stanislava Yu. , Albanova Vera I. , Guzev Konstantin S.
Published: February 2024

The functional role of sweating is not limited only to thermoregulation and excretion. There are other functions of it — the ability to enhance and maintain hydration and barrier function of the skin. Excessive sweating can lead to an exacerbation or cause many skin diseases, form psychological discomfort in a person due to wet clothes or an accompanying unpleasant odor. Primary hyperhidrosis may be an autosomal dominant genetic disease. Secondary, usually generalized hyperhidrosis is often associated with drug effects on the body or a systemic disease. The following approaches are used in the treatment of hyperhidrosis: 1) blocking the release of sweat to the skin surface (aluminum salts and formaldehyde); 2) physiotherapy (iontophoresis); 3) destruction of sweat glands and cessation of sweat production (excision of a skin flap with subcutaneous fat, curettage, microwave technology, etc.); 4) termination of the signal from the central nervous system to the sweat glands (transthoracic endoscopic sympathectomy, percutaneous radiofrequency sympathectomy, botulinum toxin injections, systemic anticholinergic drugs). External remedies for excessive sweating include the Russian drug Formagel®, containing 3.7% formaldehyde. This drug is a non-invasive, easily doable, effective, safe method of treating hyperhidrosis.

Authors: Alkhaibary Ali , Alharbi Ahoud , Khairy Sami
Published: February 2024

Background:

The “Raindrop skull” appearance represents the multiple punched-out and lytic lesions hitting a surface and creating a scattered splash pattern.

Case Description:

A 73-year-old female presented with multiple painless lumps over the forehead and head. The patient reported unintentional weight loss, fatigability, loss of appetite, fever, night sweats, and back pain for seven months (B symptoms). The examination revealed multiple, nonmobile, calvarial lesions with defined borders, measuring approximately 1 × 1 cm. Laboratory investigations of serum-free light chains showed a free kappa level of 12.91 mg/L, a lambda level of 4549.28 mg/L, and a free kappa/lambda ratio of 0.00. Radiological imaging of the skull and brain showed a “raindrop skull” appearance and multiple calvarial osteolytic lesions. The patient underwent a right superior iliac crest bone marrow aspirate and trephine biopsy. The laboratory and histopathological sections were compatible with multiple myeloma. A diagnosis of multiple myeloma (free light chain lambda) was rendered.

Conclusion:

Calvarial multiple myeloma is rare and requires a high index of suspicion to diagnose. “Raindrop skull” appearance is pathognomonic of calvarial multiple myeloma.

Изучено влияние бактерий Pseudomonas protegens DA1.2 и Pseudomonas chlororaphis 4CH, смягчающих гербицидный стресс у растений на активность фермента ацетолактатсинтазы (АЛС) и фитотоксичность метсульфурон-метила для 14-суточных растений пшеницы и рапса. Показано, что у рапса после бактеризации активность АЛС восстанавливалась до 50-59%, а вес побегов - до 79-87% от контроля. У пшеницы бактеризация нивелировала последствия пятикратного превышения рекомендованной дозы гербицида и увеличивала активность АЛС до 84-88% от контроля.
