Introduction: The frequent use of pesticides is currently considered a cause of environmental pollution due to the high rate of entry of these substances into agroecosystems. This constitutes a risk for the species that inhabit these ecosystems, in particular anurans whose characteristics make them prone to exposure to and interaction with environmental pollutants. Objective: To report the occurrence of abnormalities in larvae of the common toad Rhinella arenarum inhabiting ponds surrounded by agroecosystems. Methods: In two consecutive springs (2015 and 2016), reproductive events of common toads were monitored in temporary pond systems in agricultural and non-agricultural areas, located near the city of La Plata (Buenos Aires, Argentina). The physicochemical parameters of the ponds were measured, and the stage of each reproductive event was recorded, such as the numbers of adult toads, amplexus and clutches. In the laboratory, the larvae were measured and photographed, their stage of development was recorded, and their morphology was examined under a stereomicroscope. Representative samples (normal and abnormal) from each pond studied were processed for histopathological analysis. Results: In the field studies carried out on a population of R. arenarum collected in an agroecosystem, a lower number of reproductive adults and clutches were observed in relation to the population of a non-agricultural pond. A total of 1 910 larvae were collected: 529 and 1 381 larvae from ponds located in non-agricultural and agricultural areas, respectively. Larvae from the agroecosystem showed two types of abnormalities: severe tail flexure and abdominal bloating. In addition, five degrees of severity could be determined in relation to abdominal bloating. Conclusions: This work reports the high frequency and severity of abnormalities observed in the early stages of R. arenarum larvae living within an agroecosystem, providing evidence of the negative impact that agricultural activities cause on aquatic ecosystems surrounded by farming areas.

Published: July 2023

Introducción: La frugivoría es un proceso ecológico determinante para la estructuración y regeneración de los bosques. Particularmente en los trópicos, donde la diversidad de plantas y animales frugívoros es alta, y las relaciones interespecíficas son complejas generando redes de interacción donde las especies cumplen papeles funcionales diferenciales. Objetivo: En este trabajo identificamos cuáles son las especies de plantas ecológicamente más importantes en dos redes de interacción en un bosque seco colombiano, y determinamos cuáles rasgos funcionales de los frutos explican esta importancia. Métodos: Para ello se calculó el índice de importancia de las plantas (IIP), a partir de la relevancia de las especies de frugívoros en el mantenimiento de la estructura de las redes con las cuales interactúa cada especie. Dicha relevancia está relacionada de manera directa con el potencial que tienen los animales (aves y mamíferos) de ser dispersores efectivos de semillas. Luego, utilizando modelos lineales generalizados se evaluó cuáles rasgos funcionales de los frutos (tamaño, color, estrato, tipo de pulpa) explican el IIP. Resultados: Dentro de las plantas más importantes se encuentran especies de los géneros Miconia, Ficus, Cecropia, Bursera, Casearia y Trichilia, las cuales han sido identificadas previamente como recursos importantes para los frugívoros en los trópicos. Particularmente en este trabajo, identificamos que las plantas con frutos carnosos, rojos y de menor tamaño benefician a los mejores dispersores potenciales de semillas. Discusión: La alta variación de los valores del IIP sugiere que el conjunto de especies de frugívoros beneficiados por cada especie de planta, tiene un aporte diferencial en los procesos ecológicos derivados de la dispersión de semillas. Esta información es de gran relevancia para la selección de especies con rasgos particulares que favorezcan la recuperación funcional de los bosques a través de programas de restauración ecológica de ecosistemas tan amenazados como el bosque seco tropical (bs-T).

AbstractThe efficiency of using photovoltaic panels significantly depends on the climatic conditions and the power of the consumer. The evaluation of the efficiency of using the battery of the photovoltaic panel depending on the climatic conditions and the power of the consumer was carried out by the method of simulation modeling. A new type of storage battery allows to accumulate excess and compensate for the energy deficit due to the capacity of the batteries, and in case of their complete discharge - due to connection to other sources of electrical and thermal energy. The temperature field on the surface of the solar panel is constructed based on numerical simulation. The temperature ranges from +70.4 to +127.5 °C. In the main area of the panel, the heat flow ranged from 3,200 to 7000 W m−2.

Published: July 2023

AbstractSpeech scrambling aims to distort speech signals to prevent unauthorized listeners from understanding them, but conventional techniques are vulnerable to attacks. Therefore, more robust and secure speech scrambling algorithms are needed to ensure sensitive communication security. A proposed scheme uses a particle swarm optimization algorithm to generate a random key and optimize the level of noise in the scrambled signal, along with two transformations Multiwavelet and Arnold techniques to improve complexity and security. The proposed algorithm has been evaluated using various performance measurements and has demonstrated superior encryption performance than other similar audio encryption schemes with key space equal to 128 × 2.718. Further research and development in speech scrambling are essential to guarantee secure communication in sensitive contexts such as military and intelligence.

Published: July 2023

Neste artigo, temos por objetivo identificar, analisar e descrever metáforas verbo-gestuais e gestos metaforizados veiculados em cinco amostras pertencentes às narrativas contadas na conferência TEDx USP “A ciência brasileira e o sonho de Cassandra”, proferida por Natália Pasternak. A fim de tratarmos sobre a estruturação multimodal da narrativa, utilizamos considerações sobre os níveis narrativos e a marcação de pontos de vista. Além disso, tecemos uma discussão sobre funções comunicativas globais desempenhadas pelos gestos e expressões faciais, focalizando a função expressiva. Baseando-nos em uma adaptação aos dados do Português Brasileiro (PB), das Diretrizes de Identificação de Metáforas nos Gestos (DIM-G), focalizamos, sobretudo, as funções não referenciais desempenhadas pelos gestos. Nos resultados, foi possível identificar metaforizados dos gestos, com a veiculação de tomadas de postura e de atitudes da falante – no caso, da narradora, no nível narrativo, e da palestrante, no nível paranarrativo. De maneira mais ampla, as narrativas ilustram, tanto para a comunidade científica, quanto para um público mais amplo, a necessidade de se discutir a ciência no cotidiano.

Published: July 2023

With virtual information, cloud computing has made applications available to users everywhere. Efficient asset workload forecasting could help the cloud achieve maximum resource utilisation. The effective utilization of resources and the reduction of datacentres power both depend heavily on load forecasting. The allocation of resources and task scheduling issues in clouds and virtualized systems are significantly impacted by CPU utilisation forecast. A resource manager uses utilisation projection to distribute workload between physical nodes, improving resource consumption effectiveness. When performing a virtual machine distribution job, a good estimation of CPU utilization enables the migration of one or more virtual servers, preventing the overflow of the real machineries. In a cloud system, scalability and flexibility are crucial characteristics. Predicting workload and demands would aid in optimal resource utilisation in a cloud setting. To improve allocation of resources and the effectiveness of the cloud service, workload assessment and future workload forecasting could be performed. The creation of an appropriate statistical method has begun. In this study, a simulation approach and a genetic algorithm were used to forecast workloads. In comparison to the earlier techniques, it is anticipated to produce results that are superior by having a lower error rate and higher forecasting reliability. The suggested method is examined utilizing statistics from the Bit brains datacentres. The study then analyses, summarises, and suggests future study paths in cloud environments.

Published: July 2023

Purpose: Previous studies have reported that the conus medullaris (CM) is located between T12 and L2 in most adults, but no significant ascent has been observed during childhood. There is evidence that the normal position of the CM in an adult is acquired at birth in the majority of cases. Studies have shown that there are differences in CM levels in neonates. This situation causes problems for interventional procedures in the neonatal period. The aim of this study is to determine CM levels in preterm/term neonates using ultrasound (US).
Materials and Methods: Newborn infants (gestational age: 24–43 weeks) admitted to the neonatal intensive care unit between March 2020 and June 2021 were evaluated for CM levels by the postnatal US. Infants with central nervous system abnormalities, dysmorphic features, somatic or various genetic diseases, or their parent’s refusal to participate were excluded from the study.
Results: Of the 189 neonates infants included in our study, 85 (44.6%) were female, 104 (55.4%) were male, 139 (73.54%) were preterm (24–36 weeks), and 50 (26.46%) were term (37–42 weeks) neonates. As a result of the US performed on the first day of 189 neonates, CM levels, 31 (16.4%) were L1, 31 (16.4%) were L1-2, and 71 (37.6%) were L2. There is a strong correlation between birth weight and birth week (r 0.84). There is a negative relationship between birth weight and CM level (r -0,20), gestational age, and CM level (r -0,23).
Conclusion: Conus medullaris level was negatively correlated with gestational age and increased with advancing gestational age. In addition, the CM level shows a slower rise at 28-40 weeks of postmenstrual age and reaches the normal level (L1-L2) in the neonatal period, as in adults. Knowing the level of the CM in the newborn period will ensure that spinal procedures such as lumbar puncture to be applied to the spinal region can be performed safely.

Published: July 2023

Purpose: The focus has been on the hematological complications of iron deficiency, while the nonhematological complications have been less studied. Its effects on cognitive functions were mostly investigated in children and adolescents. The purpose of this study is to compare the executive functioning of persons with iron deficiency anemia to healthy controls in order to determine whether they have any comorbid psychiatric disorders.
Materials and Methods: 42 patients with iron deficiency anemia and 44 healthy controls participated in this study. To investigate whether any psychiatric disorders existed, the individuals were given a Structured Clinical Interview for DSM-5 Clinician's Version. Executive functioning was assessed using the Stroop Test and the Number Sequence Learning Test.
Results: When compared to the control group, the IDA group took longer on average to complete parts 1–5 of the Stroop Test. There was no difference between the groups with regards to the results of number sequence learning test. Psychiatric illnesses were more common (43%) in the IDA group than they were in the control group (13.6%). The difference was significant when the groups were compared in terms of psychiatric disorders.
Conclusion: According to the study's findings, those with iron deficiency anemia have worse executive functioning scores than healthy controls and are more likely to have psychiatric disorders. An extensive assessment of the health consequences of iron deficiency anemia is extremely important.

Published: July 2023

Purpose: COVID-19 is an unprecedented pandemic that has caused an increase in the intimate partner violence (IPV) victims rate, and social service-providing agencies shifted to emergency online and distance service-providing systems. In our study, we aimed to explore the experiences of IPV service providers during this pandemic.Method: We used a cross-sectional qualitative method containing some quantitative questions. Data were collected by conducting 15 in-depth interviews and a survey with the service providers (22–65 years old) from six IPV service-providing agencies that are located in the Dallas-Forth Worth metroplex in North Central Texas. We used a phenomenological hermeneutical method to capture the service providers’ experiences.Results: Four key themes highlight the essence of the experiences of the IPV service providers while providing the services during COVID-19. The four major themes are (a) experiences with telehealth, (b) barriers to social and legal services, (c) altered relationships, and (d) mental health impacts. In addition, a few subthemes are explored under the first three major themes. The service providers we interviewed provided details and vital information regarding challenges, adaptations, and resilience they experienced to assist the most disadvantaged group of the population.Conclusion: This study will contribute to making attention to improving facilities, accessibility, and resources for both service providers and their clients. Findings highlight the need for agency owners and policymakers to consider more multimodal and creative solutions for such a vulnerable population and their service providers.

ABSTRACT
Social media is an integral part of student life, given its enormous use as a source of information. This study examines student behavior in interacting with information using the Wilson (2000) behavioral model. This research was conducted at Universitas Muhammadiyah Sidoarjo by using a descriptive qualitative method, namely by explaining the student information behavior at Universitas Muhammadiyah Sidoarjo. Analysis of information behavior begins with an analysis of information needs. The main drivers for the creation of information needs are personal motives, namely cognitive and affective, as well as relational motives. In cognitive-based motivation, social media is used to increase knowledge which can improve self persona, both appearance and skills. The affective-based motivation is the need for sources of entertainment. Social media becoming a tool for students to express and establish their social relationship, to build an image, connecting themselves and to be a part of a group. The search for information is active, because social media provides a variety of interconnected platforms, so that information can be displayed in detail and clearly. The behavior of information utilization by students of Universitas Muhammadiyah Sidoarjo also shows their awareness of the information quality, so that a verification process is implemented to test the information accuracy.

An anomalous course of coronary arteries is fairly rare pathology, which, however, may underlie clinical manifestations of coronary artery disease. Expanding the possibilities of diagnostic coronary angiography makes it possible to detect numerous types of congenital anomalies of the coronary arteries.However, if earlier they were considered as angiographic findings and were characterized as benign, now this attitude has been changed due to reports of cases of syncope, angina pectoris, and sudden cardiac death associated with their presence. In this regard, a trend emerged to consider such anomalies as “potentially malignant”, which explains special caution at their detection. The article presents a clinical case of an anomalous retroaortic course of the circumflex artery from the right coronary artery.

Aim. To study the comparative dynamics of left ventricular (LV) remodeling after on-pump and off-pump coronary artery bypass grafting.Materials and methods. The study included 129 patients with verified coronary artery disease (CAD) who underwent coronary artery bypass grafting (CABG) with cardiopulmonary bypass (on-pump CABF) or beating heart surgery (off-pump CABG). All patients underwent transthoracic echocardiography (TTE) and volumetric compression oscillometry (VCO) before surgery, as well as one week and four months after it. The results were compared in groups divided according to the surgical technique and the presence of previous myocardial infarction using variation series, the Tukey’s post-hoc test, the Pearson correlation coefficient, and the Spearman’s rank correlation coefficient.Results. According to TTE data, no difference in hemodynamic parameters between the groups in the postoperative period was noted. According to VCO data, a significant difference was revealed in the off-pump group without previous MI one week after surgery: an increase in cardiac output (CO) (p < 0.001), an increase in stroke volume (SV) and stroke index (SI) (p = 0.005), LV power (LVP) (p = 0.015), and also a rise in cardiac index and LVP four months after the surgery. In the on-pump group of patients with previous MI a week after CABG, a decrease in the LVP (p < 0.001) and dynamic changes of energy expenditure (p < 0.001) were observed. The correlation analysis revealed moderate correlations between the inotropic parameters of cardiac hemodynamics SV, SI, CO, LVP and blood pressure (BP) (rπ = 0.33–0.47; p < 0.001) and strong correlations between SV, SI, CO, LVP and ejection fraction (EF) (rπ = 0.63–0.68; p < 0.001).Conclusion. Seven days after the off-pump CABG, an improvement in some hemodynamic parameters and all inotropic parameters of the heart was revealed compared with the on-pump group. Four months after the off-pump surgery, positive hemodynamic remodeling was observed compared with the postoperative period after the onpump CABG.
LAURUSSIAN-ASPECT OF THE COPROLITE ASSOCIATION FROM THE UPPER TRIASSIC (CARNIAN) OF THE ARGANA BASIN, MOROCCO

ABSTRACT
A large collection of vertebrate coprolites derives from a debris flow conglomerate in the Upper Triassic Irohalene Member (Carnian) of the Timezgadiouine Formation, northern Argana Basin, Morocco. The coprolites are classified into 14 different morphotypes (MA to MN) based on their size, shape, and surface texture that are divided into three groups: striated coprolites; spiral and scroll-like coprolites; and non-spiral coprolites lacking striations. The great variety of morphotypes suggests the coprolites correspond to a variety of terrestrial and aquatic carnivorous producers. The carnivore coprolites lithified rapidly and were deposited in a high-energy sheetflood. The majority of the coprolites were produced by semi-aquatic and terrestrial tetrapods, with a small percentage produced by fish.
The occurrence of Dicynodontocopros, common Alococopros, and some heteropolar forms with affinities to Heteropolacopros, are consistent with a late Carnian age for the Irohalene Member. The Irohalene coprolites are mostly similar to those of the coprofaunas of late Carnian age (Otischalkian–Adamanian) in the lower Chinle Group of the western United States in the co-occurrence of Alococopros and Dicynodontocopros. Significantly, this Moroccan coprofauna from Gondwana has close Laurussian relationships.
