A Systematic Literature Review on Malware Attacks
Authors: Habib Habiba , Rafique Insha
Published: May 2024

Modern malware is very smart and designed to attack the target. Most of these sophisticated malwares are quite persistent and have escape mechanisms. Software that is malicious is bad. Researchers in both academia and industry face significant hurdles as a result of this malware's ability to harm computers without the knowledge of their owners. Given that harmful software refers to any software that exploits computer-based systems with malware in order to compromise data security, privacy, and availability, the aim of this study is to examine the literature that has been produced on malware attacks. This will allow us to carry out an analysis of the literature and see how the research has progressed in terms of quantity, content and means of publication. One cannot understand all aspects of most malware programs as they are so large and sophisticated. The correct implementation and use of anti-malware programs, as well as the education of Internet users about malware attacks, are crucial steps in defending the identity of online shoppers from malware attacks. Some of the shortcomings of screening approaches that need to be corrected for better screening were noted in critical appraisal of the study.

Published: May 2024

A pesquisa teve como objetivo investigar representações sociais de ser negra com deficiência por estudantes negras com deficiência na escola. A Teoria das Representações Sociais (TRS) foi tomada como referencial teórico-metodológico do estudo. Participaram sete estudantes, meninas matriculadas no Ensino Fundamental de uma escola pública municipal do estado do Rio de Janeiro. A pesquisa teve natureza qualitativa, e a geração de dados foi realizada com uso do Teste da Boneca 1 e 2. No primeiro, duas bonecas, uma preta e outra branca, foram colocadas diante de cada estudante, para que respondessem a algumas questões. No segundo também foram utilizadas duas bonecas, uma preta e outra branca, no entanto a branca com amputação da perna direita acima do joelho e utilizando muletas. As conversas, feitas individualmente, foram registradas por meio de videografia e analisadas com apoio da análise microgenética, baseada em referencial vygotskyano. Os resultados permitiram propor, como hipótese interpretativa, um modelo figurativo da representação social de “ser negra com deficiência” que se objetivou na imagem de “ser feia”, associada a “cabelo ruim”, “má” e “diferente”. Além de expor a experiência do racismo estrutural vivenciado pelas participantes, a pesquisa mostrou que a ausência dessas discussões no contexto escolar dificulta a inclusão e a construção da identidade negra com deficiência por elas.

Published: May 2024

In this study, nanocrystalline ZnO were synthesized onto glass substrates by using sol-gel method. Structural characterizations were performed by XRD, SEM and AFM techniques. Potential application of nanocrystal ZnO as chloroform sensor was investigated. Response of the fabricated thin films of the ZnO nanocrystals towards chloroform vapor was investigated depending on gas concentration (750-15000 ppm) between the temperatures of 22‒150 ºC in nitrogen ambient. Gas flow rates were controlled by using flow controller and flow meters. All the measurement system was computerized.
XRD results revealed that thin film of the ZnO nanocrystals on the glass substrate was in crystal form and can be characterized by 036-1451 JCPDS number. Crystallite sizes of the ZnO nanocrystals were determined both by SEM images and the Scherrer equation. The crystallite sizes were calculated between 27.9 – 50.4 nm using the Scherrer equation. The sensors showed reversible response towards the chloroform vapor in the measured temperature and gas concentration range. Response time and sensitivity values of the sensors towards the chloroform vapor were also calculated. The increase in temperature caused to increase in sensitivity values. The best sensitivity values were obtained at 150 ºC.

Green Synthesis, Characterization and Antibacterial Activities of Silk Sericin Capped Zinc Oxide Nanoparticles
Authors: Temel Aleyna , Gün Gök Zehra
Published: May 2024

In recent years, interest in metal-based antibacterial materials has increased due to microorganisms gaining resistance to antibiotics. Silk sericin obtained from Bombyx mori cocoon has found use in many different areas thanks to its biocompatibility, hydrophilic character and biodegradability. Zinc oxide nanoparticles (ZnONPs) obtained in various zinc salts exhibit broad-spectrum antibacterial properties. In this study, to be produce metal based antibacterial materials, synthesis of silk sericin-coated ZnONPs (SS-ZnONPs) in a green and scalable method was investigated by using silk sericin protein as both reducing and capping agent to obtain ZnONPs. For producing SS-ZnONPs, 2% silk sericin solution was mixed with Zn(NO3)2 solution and the blend solution was heated at 100 °C for a certain period of time. Observing surface plasmon resonance (SPR) peak specific at 380 nm in the UV-vis spectrum of SS-ZnONPs represented the formation of ZnONPs. Then, the chemical, morphological, crystalline, thermal, and antibacterial properties of the synthesized SS-ZnONPs were examined. Characteristic peak of the Zn-O band was found in fourier transform infrared spectroscopy (FTIR) analysis of SS-ZnONPs. According to scanning electron microscopy (SEM) analyses, ZnONPs had morphology similar to cubic/hexagonal shape, showed a uniform structure, and did not represent any agglomerations. In energy dispersive spectroscopy (EDS) analyses of SS-ZnONPs, peaks belonging to carbon, nitrogen, oxygen, sulphur, and zinc elements were observed. The formation of Zn peak indicated that the zinc ions were transformed into ZnONPs. In addition, characteristic peaks of zinc were seen in the X-ray diffractometer (XRD) result of SS-ZnONPs. Thermogravimetric analysis (TGA) showed that the thermal stability and remaining amount of SS-ZnONPs was higher compared to pure silk sericin powder due to the formation of ZnONPs. Lastly, agar well diffusion test was carried out with Staphylococcus aureus (ATCC 6538) and Escherichia coli (ATCC 25922) bacteria and SS-ZnONPs showed antibacterial action against S. aureus. It has been observed that the obtained SS-ZnONPs can be used as antibacterial agents. However, it was also understood that the ZnONPs concentration in this study was low for high antibacterial activity.

Published: May 2024

Three-leaved Cayratia, a perennial climber, is widely distributed in India, Asia, Africa, and Australia. In Vietnam, it is found in the Mekong Delta with a specific aroma, dark purple berries, and contains an abundant source of bioactive compounds (yellow waxy oil, steroids/terpenoids, flavonoids, and tannins) in whole plants. Taking advantage of the raw source might enhance various fermented juice drinks and increase income for denizens. The initial parameters were pH 3, 4, and 5 with the total soluble solids (TSS) of 18, 20, 22, and 24 °Bx, respectively, to determine the appropriate Cayratia cider making condition. The yeast concentration (0.1, 0.15, 0.2, and 0.25% [w/v], respectively) and fermentation time (24, 48, and 72 h, respectively) at room temperature (28 ± 2°C) were also surveyed. Thereafter, the final product was analyzed for the sensory quality and microbiological and chemical criteria. The fresh Cayratia juice has a pH of 3.2 and 6 °Bx, and the juice recovery efficiency was 74%, equivalent to 0.74 L/kg of the fruit juice amount after squeezing. The low alcoholic juice has 4.62% v/v ethanol content which meets the Vietnam National Standard (TCVN 3215:79, and QCVN 6-2: 2010/BYT) after 72 h of fermentation time. The TSS of 22 °Bx, pH value of 4, and yeast concentration of 0.2% (w/v) are appropriate initial conditions for Cayratia juice with low ethanol content. Cayratia cider with 4.6% (v/v) ethanol content was produced by Saccharomyces cerevisiae HG 1.3 at room temperature 28 ± 2°C with initial TSS of 22 °Bx, pH 4, and inoculation yeast rate of 0.2% w/v. The quality analysis meets Vietnamese standards for food consumption.
Gender Differences in Cognitive Abilities in Human Adults
Authors: Nanova Plamenka , Kolev Vasil , Yordanova Juliana
Published: May 2024

Modern world of globalization and unification is of particular interest considering the rapid changes in men's and women's dispositions and engagement in societal institutions. According to these contemporary developments of the psychosocial context, cognitive differences between females and males may also be changing. The aim of this study was to update findings from the last two decades regarding gender differences in cognitive abilities.
Major updated results confirm earlier studies and demonstrate relevant gender differences in spatial abilities, verbal skills, emotional processing and executive functions. Like earlier studies, the new data also show small to trivial gender differences in mathematics performance, yet gender effects on complex problem solving are found to be smaller than in 1990 meta-analyses.
The updated data confirm that gender differences in cognitive abilities do exist despite the increasing unification of men's and women's involvement in psychosocial contexts. Moreover, new scientific approaches demonstrate that these gender-specific cognitive differences are grounded on hormonal, neuroanatomical and neurofunctional substrates emphasizing their biological origin. Although the psychosocial interaction is of relevance, the primary biological basis of gender differences should be very strongly and carefully considered.
Past Distribution of the White-tailed Eagle (Haliaeetus albicilla (Linnaeus, 1758)) in Bulgaria – Subfossil Record
Authors: Boev Zlatozar
Published: May 2024

The oldest remains of the White-tailed eagle in Bulgaria came from the Neolithic-Chalcolithic (6000–4000 BC). Five Holocene localities of the species have been established in the country, in which a total of 24 bone finds of at least 10 individuals have been found. It is thought that, as in other countries in Europe, from at least the Iron Age to the late Middle Ages, large primaries and rectrices of these eagles were used to produce stabilizers for the hunting arrows of ancient hunters. All localities are located in North Bulgaria along the Danube and Black Sea coasts, but always adjacent to another water body (lake, marsh or river).

Published: May 2024

This study employs a comprehensive approach, utilizing conventional meteorological observation data, Fengyun satellite cloud imagery, and ERA5 reanalysis data to examine a short-term heavy rainfall event and its underlying causes in Shandong Province from August 14 to 16, 2020. The findings reveal that: (1) This event represents a typical Mesoscale Convective Complex (MCC)-induced rainfall process, with the primary precipitation zone in central and southern Shandong. The most intense hourly rainfall is observed along the side of the MCC with the steepest Tropical Brightness Temperature Blackbody (TBB) gradient. The heaviest hourly rainfall happens right around the time of the lowest TBB interval. (2) The rainfall event is marked by a vertical atmospheric structure with a high-altitude westerly jet and a low-level southwest jet, which makes it easy for water vapour to move and shear lines to form. Favourable conditions for water vapour convergence and high specific humidity are noted. During episodes of heavy precipitation, there is a marked upward motion in the lower troposphere, aligning with the vertical pattern of low-level convergence and high-level divergence.

Authors: Erdem Tuğrul , Gücüyen Engin
Published: May 2024

Elevated storage tanks are used to store fresh and waste water, cereal, oil and petrochemical materials. Therefore they serve in a wide area of utilization in this day and age. Analysis of a half full with water elevated storage tank is performed in the scope of this study. The structure is composed of a steel circular storage tank and frame typed steel stager. The structure is under the effect of earthquake loads as well as operational ones. Numerical model is generated by Finite Elements Analysis (FEA) software including fluid and structure parts. The interaction of the parts is provided by Coupled Eulerian Lagrangian (CEL) technique. While the structure constitutes the Lagrangian part, the fluid constitutes the Eulerian part. Interaction of Eulerian and Lagrangian parts are provided by general contact algorithms. Free surface movement of the water, maximum displacements and natural frequency values with related mode shapes of the structure are obtained after numerical analysis. Numerical results are verified by semi-analytical model, where the structure is modelled as single degree of freedom system. The accordance between results is numerically and visually obtained. The turbulent movement of water under the influence of an earthquake is modelled by utilizing the CEL technique. So, the effect of the dynamic pressure induced by the turbulence on the tank and the structural system has been taken into consideration.

Modelling of resolved scaling relations in simulated galaxies
Authors:   , Cornejo Cárdenas Anell
Published: May 2024

We developed a new numerical tool, called SpecGSG (i.e. Spectra Generator of Simulated Galaxies), which aims to generate synthetic spectra of simulated galaxies in order to improve comparisons between simulations and observations. Through this code we can obtain spatially resolved spectral information that considers the contribution of stellar populations and the nebular emission produced by gas close to young stellar populations. A fundamental aspect of this tool, and what differentiates it from other previous works (e.g., Nanni et al. 2022), is that the nebular emission is calculated based on the properties of the gas surrounding recently born stellar populations. This code allowed us to study both the intrinsic properties of the simulations and the properties we derived from their synthetic spectra. From the intrinsic properties of the simulations we found an anti-correlation between the ionization parameter and gas metallicity. Additionally, we used SpecGSG to recover spatially resolved scaling relations using the synthetic spectra generated from the simulated galaxies in local regions. In particular, we focused on two scaling relations: (1) the spatially resolved star-forming main sequence (rSFMS), i.e. the relationship between the Star Formation Rate surface density (ΣSFR) and the stellar mass surface density (Σ∗), and (2) the spatially resolved mass-metallicity relation (rMZR), i.e. the relationship between the gas-phase metallicity and Σ∗. From these synthetic spectra, we found that the metallicity has a first dependence on Σ∗ and a second dependence on ΣSFR. This agrees with results obtained in observations of galaxies. Therefore, SpecGSG allows us to calculate the properties of the simulations from a more observational way, improving comparisons between observational and simulation data. At the moment, SpecGSG only implements a simple model of dust that downgrades the spectra due to its presence in the star-forming regions. The treatment of dust attenuation and re-emission along the line of sight between each emitting source and the observer, will be implemented in a future work.
Detection and characterization of hot Jupiters around hot stars

Published: May 2024

El objetivo principal de esta tesis es abordar el desafío de detectar y caracterizar Júpiteres calientes alrededor de estrellas calientes. La elevada temperatura de las estrellas dificulta la confirmación de exoplanetas debido a la rápida rotación estelar, lo que resulta en una menor precisión en las mediciones de velocidades radiales. Un método para caracterizar y confirmar planetas que orbitan este tipo de estrella es el de Tomografía Doppler (TD). En este trabajo, se desarrolló un método de TD, en un marco bayesiano y se probó en seis sistemas. Se utilizaron datos publicados de tres de ellos (WASP-19b, KELT-7b y HAT-P-56b), obteniendo resultados visuales similares a los publicados. Para dos sistemas (HD2685 y TOI-812), se predijeron y observaron los tránsitos, pero no fue posible recuperar la señal del planeta. Y un sistema que será publicado prontamente (TOI-3362-b, Espinoza et al. in prep) que es consistente con la alineación del sistema. También se construyó un catálogo de siete estrellas (incluyendo HD2685b) interesantes para nuestro estudio. Este catálogo se construyó a partir de una selección de estrellas calientes (hecha con datos de Gaia DR2) que poseían altas señales de tránsito en las curvas de luz obtenidas de TESS. De esas siete estrellas, cuatro poseen planetas ya confirmados y tres candidatos a planeta, de especial interés debido a las características únicas de cada sistema. También se desarrolló un código capaz de predecir la observabilidad de la Tomografía Doppler, considerando las características de la estrella, el planeta y el instrumento utilizado para la observación. Las conclusiones de este estudio indican que tanto el método de deconvolución como el modelo de predicción de Tomografía Doppler son útiles y consistentes con trabajos previos. Sin embargo, es necesario desarrollar nuevas herramientas para cuantificar la precisión de estos métodos.
Essays on economics of the family
Authors:   , Sierra Campodónico Alejandro Carlos
Published: May 2024

Mi trabajo aborda dos dimensiones de la economía de la familia: la elección de pareja y el papel de la violencia en las relaciones. En el primer capítulo, se explora la relación entre los métodos modernos de búsqueda de pareja, como las plataformas en línea, y el aumento de la homogamia en los Estados Unidos. Se descubre que los individuos considerados más atractivos, ya sea por su nivel de educación o edad, son menos propensos a utilizar métodos de búsqueda en línea. El modelo propuesto indica que métodos de búsqueda más eficientes pueden fomentar un mayor emparejamiento assortativo, lo cual podría resultar beneficioso bajo ciertas circunstancias. El segundo capítulo, coautorado con Alexandre Janiak y Jeanne Lafortune, analiza la compleja relación entre las leyes de divorcio más flexibles y la prevalencia de violencia en la pareja. El modelo teórico sugiere que la liberalización del divorcio puede tener un impacto mixto en los índices de violencia, dependiendo del contexto cultural y de la capacidad para realizar transferencias económicas entre los cónyuges. Este enfoque ofrece una visión más matizada y reconcilia hallazgos empíricos previos, contribuyendo a una comprensión más profunda de cómo las dinámicas legales y culturales afectan las relaciones familiares.
La Filomena (1621) de Lope de Vega: recurso visivo e imaginería mitológica en un epilio barroco
Authors:   , Ramaciotti Godoy Amalia
Published: May 2024

La presente tesis de investigación aborda un estudio sobre las figuras retóricas reunidas dentro de la miscelánea La Filomena (1621) de Lope de Vega. Dichas figuras son analizadas en torno al criterio implementado por el poeta para narrar cruentos sucesos cometidos dentro de la trama original ovidiana, que llaman la atención desde el decoro y el manejo de las pasiones. Los principales ejes de estudio corresponden, en primer lugar, a la influencia barroca y la relevancia del uso de la imagen como vehículo visivo y simbólico durante el Siglo de Oro, que dialogan con la poesía lopiana desde el uso de la metáfora, alegoría y écfrasis. En segundo lugar, a propósito de los estudios sobre imago y barroco de Fernando Rodríguez de la Flor, se investiga acerca del género épico barroco –epilio– bajo el cual se define la obra estudiada de Lope, con el influjo constante de la materia clásica y mitográfica. En tercer lugar, importa la influencia mitológica en la nueva versión de la épica durante el barroco español a partir del trabajo de Rosa Romojaro, quien dedica su investigación a la función del mito clásico en la poética de Lope de Vega. A partir de la imagen y las figuras literarias comparativas –alegoría y metáfora–, es posible reunir un entramado visual/retórico presente en La Filomena que refleja una función principalmente erudita y una principalmente vindicativa por parte del poeta.
Oestrogen and Gastroesophageal Reflux Disease Dynamics in Premenopausal and Postmenopausal Women: A Cross-sectional Study
Authors: Praveena M , Nagashree R
Published: May 2024

Introduction: Gastroesophageal Reflux Disease (GERD) is a common clinical disorder characterised by the reflux of stomach contents into the oesophagus, primarily due to the temporary relaxation of the Lower Oesophageal Sphincter (LES). The aetiology of GERD is multifactorial. The prevalence of GERD in females has been found to sharply increase throughout the postmenopausal period compared to the reproductive phase. Aim: To study the relationship between serum oestrogen levels in premenopausal and postmenopausal women with GERD. Materials and Methods: In this cross-sectional study, 60 patients with GERD were divided into 30 premenopausal and 30 postmenopausal groups. The study subjects underwent high-resolution oesophageal manometry. The Cobas e 411 immunoassay analyser was utilised to measure serum oestrogen levels through electrochemiluminescence. The independent, unpaired Student's t-test was employed to analyse the collected data. Results: The statistical analysis revealed that the mean reduced LES pressure of 9.76±3.80 mmHg and the mean reduced Oesophagogastric Junction Contractile Integral (EGJ-Cl) of 14.503±10.64 mmHg were lower in women with postmenopausal GERD who exhibited lower oestrogen levels compared to those with premenopausal GERD. An increase in LES pressure was also associated with an increase in EGJ-CI, demonstrating a statistically significant positive linear correlation between LES pressure and EGJ-CI. The p-value <0.05 was deemed highly statistically significant. Conclusion: Parameters such as basal LES pressure and EGJCl were observed to be reduced in postmenopausal women with GERD who had low oestrogen levels. This study suggests that oestrogen plays a crucial role in safeguarding the oesophageal epithelium against the reflux of gastric contents.

Published: May 2024

The present study was conducted to find out the intensity of communication of tribal goat farmers with different stakeholders to improve their livelihood. Kandhamal district of Odisha was purposively selected for the study as this district is highly concentrated with local goats. From randomly selected four blocks of the district, four villages were also selected randomly from each block. Thereafter, seven goat farmers from each village were selected randomly which constitute the sample size of 112 goat farmers for the study. The data for the study was collected personally by the researcher with the help of pre-tested interview schedule. The study employed ex-post facto research design to capture field data. Communication impact a component of overall livelihood impact was measured with the help of 10 validated statements in a five-point Likert type scale with scores on a continuum with 1(strongly disagree) to 5 (strongly agree) for each of the statement. The study revealed that the farmers exposure to mass media, and interactions with professionals of veterinary department has increased due to goat farming. However, their overall communication impact is medium in nature indicating that the important stakeholders including government agencies involved in promotion of goat farming in the tribal areas should put emphasis on improving the communication ability of the famers which will be useful to them to access relevant information for strengthening their livelihood.

Mindful attention awareness involves intentionally being attentive to the current moment without bias, allowing focus on the current moment and what is most important to you, rather than concentrating on thoughts and feelings. This study explores whether mindful attention awareness has significant differences in sex, year level, and department. This research is quantitative and employs a descriptive-comparative design. The data interpretation is performed by JAMOVI software, together with Excel. The Shapiro-Wilk test was utilized to assess normality, but it did not confirm a normal distribution for continuous variables, while mean and standard deviation were used to measure variable levels. The findings revealed that respondents had a moderate range in all sub-scales in the area of mindful attention awareness. The results showed that females had a high significance difference in mindfulness attention awareness. The test of difference shows that sex has an unequal variance, while in year level, only first, second, and fourth-year students had a significant difference in mindfulness attention awareness, and the department had no significant difference in mindfulness attention awareness. The study recommends future researchers on exploring the longitudinal effects of mindfulness interventions on academic achievement and student well-being, which could provide valuable evidence for integrating mindfulness into educational practices.
