Published: June 2023

Este artículo analiza, desde una perspectiva feminista interseccional, las condiciones de trabajo productivo y reproductivo de mujeres migrantes que trabajan en el agro de Mendoza, Argentina, con la finalidad de evidenciar sus aportes a la producción y la reproducción social. Se exponen parte de los resultados de una investigación más amplia sobre experiencias de salud, enfermedad y cuidados de estas trabajadoras. En términos metodológicos, se trata de un estudio etnográfico que se apoyó especialmente en los relatos de vida de las mujeres y cuyo trabajo de campo se desarrolló entre 2014 y 2018 en Ugarteche, localidad mendocina dinamizada por la agricultura y las migraciones internas y limítrofes. Los principales hallazgos del trabajo muestran, por un lado, que para comprender las condiciones de trabajo de las mujeres es necesario considerar el continuo de actividades productivas y reproductivas en que se desarrolla su vida. Por otro, el peso que imprimen las desigualdades de clase, raciales y de estatus migratorio en las cargas domésticas y laborales de las trabajadoras.
Las mujeres en aislamiento por COVID-19: Tiempos de cuidado, tareas domésticas, comunitarias y Teletrabajo.
Authors: Bonavitta Paola , Bard Wigdor Gabriela
Published: June 2023

Este artículo analiza, desde un enfoque feminista decolonial, la sobrecarga de trabajos del cuidado, domésticos y de teletrabajo que asumen las mujeres durante la pandemia por COVID-19 y en aislamiento social. Metodológicamente se realizó una encuesta y entrevistas semiestructuradas en Argentina, donde se evidencia las sobrecargas de trabajo que asumen las mujeres que no son contempladas por los gobiernos capitalistas y patriarcales, provocando que ellas deban soportar los costos económicos, físicos y psíquicos de la crisis. Se perpetúan las desigualdades de género y clase en la distribución de las tareas, tanto al interior de los hogares, como desde el Estado y el mercado, tornando urgente la redistribución y reconocimiento de estas múltiples jornadas laborales feminizadas.
La emergencia del movimiento feminista en el estallido social chileno
Authors: Ibáñez Carrillo Fabiola , Stang Alva Fernanda
Published: June 2023

Se analizan algunas de las formas en que emergió el movimiento feminista en el estallido social en Chile, centrándose en el proceso de politización no institucional del movimiento y el recurso al cuerpo y las emociones para performar la protesta; aspectos presentes en una genealogía reciente del feminismo, considerando dos hitos: las tomas universitarias feministas de 2018 y la manifestación del 8M de 2019. Se realizó análisis documental de un corpus de notas de prensa sobre los tres acontecimientos y petitorios de las tomas. Proponemos que el feminismo puede ser entendido como un hilo de continuidad que hace inteligible esta serie de procesos que, de otra manera, no podrían ser interpretados: nuevas formaciones y subjetividades políticas, que emergen del desborde de la institucionalidad.
“Eu sei aonde eu devo ir, eu sei o que eu posso vestir!”: Compreensões feministas no feminejo de Marília Mendonça
Authors: Guimarães Rossi Jean Pablo , Pironi Isabela Daiane , Maio Eliane Rose
Published: June 2023

O sertanejo é um gênero musical marcado há décadas pela predominância de cantores homens, bem como por canções que reforçam o sistema patriarcal e a objetificação da mulher sob a visão masculina. No entanto, na última década, a presença de mulheres cantoras tem despontado na vertente que ficou popularmente conhecida como “feminejo”, ou seja, o sertanejo protagonizado e cantado “por e para as mulheres”. No bojo desta discussão, objetivamos discutir como algumas canções presentes no feminejo têm se aproximado de discursos correlatos ao feminismo, no sentido de subverter ou reverberar o sistema machista-patriarcal. Para tanto, ancorados/as nos Estudos Feministas e Estudos de Gênero, analisamos duas músicas da cantora Marília Mendonça (1995-2021), a saber: Supera (2019) e Você não manda em mim (2021). Os resultados apontaram que as composições transitam entre os conceitos de sororidade, empoderamento feminino e desestabilização da ideia de dominação masculina.

Authors: Kartika Asmarani Yolanda , Kristanto Yanuar , Putri Annisa
Published: June 2023

Most complaints in dentistry today are about swelling and mobility of the tooth, and the diagnosis of an inflammatory lesion is generally made in both complaints. Burkitt's lymphoma (BL) is a type of malignant tumor classified as Non-Hodgkin's Lymphoma (NHL) with clinical symptoms of swelling dan tooth mobility similar to the inflammatory lesions. This paper aims to describe the similarities between inflammatory lesions and Burkitt's lymphoma. Burkitt's lymphoma can be classified into endemic, sporadic, and human immunodeficiency-related. Sporadic BL (sBL) occurs in approximately 12 to 30% of maxillofacial patients and commonly affects children. Several case studies reported that the clinical symptom of sBL is swelling. It has been reported in Europe and Asia that sBL in children shows swelling and tooth mobility in the maxillary and mandibular regions. Enlargement and redness of gingival tissue, hypermobility of the tooth, and swelling of the gingival around the painful tooth were reported as sBL cases after some examination. Inflammatory lesions such as BL-like have similar clinical symptoms, so the dentist must be careful in diagnosing cases of swelling and tooth mobility.
THE EFFECT OF GREEN BETEL LEAF EXTRACT IMMERSION ON NICKEL ION RELEASE IN STAINLESS STEEL ORTHODONTIC BRACKET
Authors: Trisnawaty Nety , Nida Fathiya Aufa
Published: June 2023

The orthodontic bracket is an essential component in fixed orthodontic appliances. One of the materials commonly used in orthodontic brackets is stainless steel. Stainless steel orthodontic brackets have good deformation and corrosion resistance. Still, corrosion resistance is compromised by certain conditions in the oral cavity, such as salivary pH due to food and beverage consumption and toothpaste and mouthwash. One of the herbal plants that are widely used for dental and oral health is green betel leaf. Green betel leaves have an acidic pH that may cause corrosion. Corrosion has a detrimental effect on the brackets because it causes a continuous loss of nickel ions. The purpose is to determine the number of nickel ions released from stainless steel orthodontic brackets due to immersion in the green betel leaf extract. This type of research is a laboratory experimental research design with a post-test control group design. The test was carried out on 27 samples divided into three groups. Brackets were immersed in 25% green betel leaf extract, artificial saliva, and a mixture of 25% green betel leaf extract and artificial saliva for 48 hours and measured using an Atomic Absorption Spectrophotome (AAS). The results showed the most significant release of nickel ions occurred in the 25% green betel leaf extract group with a value of 16.37 mg/Kg, and the minor release of nickel ions occurred in the artificial saliva control group with a weight of 1.95 mg/Kg. The conclusion is that green betel leaf extract influences the release of nickel ions in stainless steel orthodontic brackets.

Published: June 2023

Aim of study: To characterize and compare the genetic resources and gain some insights into the evolutionary history of Aleppo pine (Pinus halepensis Mill.) and Brutia pine (Pinus brutia Ten.) species which are both distributed across more than 8 million hectares of area in the Mediterranean Basin. Study area: Fifty-six populations from eight Mediterranean basin countries where P. halepensis and P. brutia species are located. Materials and methods: We analyzed 1344 seeds belonging to 56 populations using five cpSSR primers (Pt15169, Pt30204, Pt41093, Pt87268, and Pt110048). Main results: The analysis of molecular variance (AMOVA) revealed that the genetic diversity among the Brutia pine populations was slightly higher than that of Aleppo pine (27.06% and 24.27%, respectively). The Aleppo pine populations separately displayed a clear east-west differentiation across the Mediterranean Basin, confirming previous results using other markers. Although the Brutia pine populations showed no spatial genetic pattern, geographically close populations and/or populations from their continual distribution range were genetically closer than the fragmented and/or ecologically marginal populations. Research highlights: The seven Aleppo pine populations from the eastern range (Türkiye, Greece, and Italy) were more than two-fold diverse than the 13 populations from the western range (Spain and Morocco). The eastern range of Aleppo pine and Brutia pine populations had similar levels of genetic diversity parameters. These results suggested that the Eastern Mediterranean Basin is a possible genetic diversity center for the two pine species.

Authors: Yao Jinzi
Published: June 2023

With economic growth, ship transportation plays a major role in global logistics. The optimization of the ship form based on minimum resistance has been the research focus of ship builders for hundreds of years, but the actual process is quite complex, which also brings huge benefits. Ship drag reduction is not only conducive to industrial economic growth, but also helpful to improve the global energy consumption and environmental problems. In this paper, the Reynolds number and the Froude number are obtained by a dimensional analysis, and then the data are obtained from the model ship experiment with the same Froude number by the law of similarity. The total resistance is subdivided into four kinds with different causes, namely the friction resistance, wave-making resistance, form resistance, and additional resistance. In this way, the ship resistance can be reduced more scientifically and efficiently.

Authors: Xia Zixuan
Published: June 2023

The study of the properties of analytical functions is described as complex analysis. The residue theorem is an important conclusion in complex analysis. This paper introduces the origin of imaginary numbers from Cardano Formula defines the conversion of complex number formats from the Euler Theorem, and proves the intermediate theorem Cauchy Integral Formula before reaching our final conclusion and the goal of the paper, Residue Theorem. The name of the theorem comes from the concept of residue, which is defined using a functions Laurent series. We could then derive the Residue Theorem from the Cauchy Integral Theorem, also called the Cauchy-Goursat Theorem. We will be able to formalize our prior, ad hoc method of computing integrals over contours encompassing singularities. Additionally, it is a theorem that may be applied to zero-pole qualities and curved integral properties. The Residue Theorem is the basis of many essential mathematical facts revolving around line integrals, particularly in solving ODEs and PDEs and describing physics models.
Review Of Dark Matter

Published: June 2023

Dark matter is counted as two of the significant discovery and research topics in the academic and scientific fields. Found later that dark matter does not belong to any of the present areas of known matter, dark matter was discovered in the late 19th century and early 20th century by indirect measuring of the abnormal velocity and mass dispersion pattern detected by multiple astronomers and mathematicians. In the last several decades, scientists from different physics fields have determined the property, location, potential candidate, origin, and interaction of dark matter. Starting with the history of the discovery and research of the dark matter, the dark matter property will be illustrated in the abstract. One of the properties of dark matter is the property that dark matter does not absorb, reflect or interact with any photons and any kinds of electromagnetic waves. The two potential dark matter candidates are WIMP (weakly interacting massive particle) and axion. The reason the scientist suspected that the two particles are the candidate for dark matter is also listed. Experiments about the candidates and other observations and theories are also listed in the paper.

Published: June 2023

Intubation is an emergency medical procedure used to rescue people who are unconscious or unable to breathe on their own. In the process of tracheal intubation, traditional intubation is difficult due to narrow viewing angle, trachea bending, and occlusion of internal structures. Thanks to the rapid development of simultaneous localization and mapping (SLAM) and virtual reality (AR) technologies, intubation aids are also developing towards intelligence and automation. Based on the collection and analysis of a large number of literatures, this paper conducts an in-depth study of the existing SLAM-based intubation-assisted technology. Specifically, on the basis of analyzing the current research on the application of equipment, visualization schemes, and algorithm schemes in tracheal intubation and intubation training, this paper studies the application progress in terms of efficiency, versatility, accuracy, and user feedback. Further, we summarize the existing key issues and discuss future developments.
The Study for Convolutional Neural Network and Corresponding Applications
Authors: Chen Xingchen
Published: June 2023

Deep learning is a key technological tool in the field of image identification with wide application prospects because of its significant benefits in feature extraction and model fitting. Deep learning entails numerous stages of non-linear transformations. The primary implementation of the current deep learning technique is the deep neural network, the connection pattern of which takes its reference from the way that the visual cortex of animals is organized. Among all the deep learning methods, Convolutional Neural Network (CNN) is one of the most renowned means to process image. It has excellent performance in terms of large-scale image processing. A convolutional neural network consists of convolutional layers, a fully connected layer, a pooling layer, and associated weights. Convolutional neural networks have fewer parameters to consider than other deep, feed forward neural networks, making them an attractive deep learning architecture. There are several traits in CNN, including pooling, shared weights, and local connections. With the help of these features, the network's complexity and the quantity of training parameters can be decreased, and the model's level of invariance to scale, shift, and distortion can be increased, along with its robustness and fault tolerance. This paper firstly summarized the history of convolutional neural network, then briefly discussed the components like the neuron and multilayer perception. The main structure of the CNN is showed afterwards. The paper also mentioned the features and the applications of CNN, mainly in the field of Computer Vision (CV).

FineTuning-based BERT for Spam Emails Identification
Authors: Meng Qingyao
Published: June 2023

In this world of information explosion, people require more effective ways to filter useful information from millions of data. Email as one of the most frequently used form of communication, carries important messages, yet along with messages of fake news, misinformation and scams known as spam emails. Manually categorizing them from non-spam emails requires a lot of time and money and other human along with material resources. In order to deal with this, deep learning, or natural language processing models in particular, is introduced to categorize emails faster and cheaper. The Natural Language Processing model used here is called Bidirectional Encoder Representations from Transformers (BERT). Since BERT is already a pre-trained model, the main task is to do the Fine-Tune part on it, with a dataset that contains around 5000 emails (85% spam emails and 15% non-spam ones). After that the model is tested on a group of 5 emails including 3 commercials/spams and 2 non-spam emails. The result shows that this model could separate them by giving commercials scores closer to 1 (spread from 0.5 to 0.7) and non-spam emails scores close to 1(spread from 0 to 0.1). Therefore, it can be concluded that this model works on small sets of data.

Authors: Zhou Ziyang
Published: June 2023

Petroleum is mainly used in the transportation industry and it is now becoming rarer in the world. Petroleum Geologists and analysts have predicted an imminent global peak of petroleum consumption, at which the maximum rate of petroleum extraction will be reached, and then followed by an irreversible decline. To date, 50 countries have passed the point of no return. Therefore, there is no time to delay the saving of petroleum. Since petroleum is mostly used by various means of transport, vehicles that are more efficient with less use of petroleum are needed. Under this context, this paper introduces three types of vehicles making full use of energy. Through case studies, the development tendency of future vehicles is illustrated, and a conclusion can be drawn that clean energy hybrids and hydrogen-powered fuels have become a future development trend for vehicles.

First Measurement of Extreme Ultraviolet Dust Extinction Curve in Quasars
Authors: Liao Jinbin , Guan Ruohan Hamilton , Ji Tuo
Published: June 2023

Dust is a ubiquitous feature of the cosmos, impinging directly or indirectly on most fields of modern astronomy. Dust grains composed of small (submicron-sized) solid particles pervade interstellar space in the Milky Way and other galaxies: they occur in a wide variety of astrophysical environments, ranging from comets to giant molecular clouds, from circum-stellar shells to galactic nuclei. The study of this phenomenon is a highly active and topical area of current research. Dust absorbs optical and Ultraviolet (UV) photons and re-emit them in the infrared. The heating and cooling of dust interact with their environment closely. Dust is closely related to the star formation process, and study on dust could put constraints on the star formation history. While extensively studied in the optical, the extinction property of dust in the UV is still an open question. UV photos are absorbed by earth atmosphere and cannot be accessed from ground-based observations. NASA space mission Galaxy Evolution Explorer (GALEX), on the other hand, provides critical data to this question by surveying the whole sky in two UV bands. By comparing the optical and UV properties of blue and red (dust-absorbed) quasars selected from Sloan Digital Sky Survey (SDSS), we shape the extreme UV dust extinction curve for the first time. The measured UV dust extinction curve will help us characterize the size distribution of dust grains and their compositions which could not be easily accessed by other methods.

Application of Remote Sensing Technologies in Environmental Monitoring and Geological Surveys
Authors: Zhou Qifeng
Published: June 2023

Remote sensing technology is an emerging observation technology. By applying various sensing instruments to electromagnetic wave information radiated and reflected by distant targets, it is collected, processed, and finally imaged. The resulting images allow people to detect and identify various scenes on the ground. It can dynamically reflect changes in the ground, monitor weather conditions, natural disasters, etc. This paper combines the relevant literature to synthesise the technical theory and specific applications of remote sensing technology in four areas: vegetation, soil, water resources and geology. The analysis of the vegetation index allows for the classification and dynamic monitoring of vegetation. Soil indicators can be monitored to determine the condition of the soil in an area, including soil contamination, soil erosion and land salinisation. The distribution of water resources in an area, runoff prediction and water quality monitoring can also be monitored by remote sensing technology. The technology can also be effective in mineral exploration and monitoring geological disasters. Although remote sensing technology has unique strengths in these four fields, there are still some technical limitations and shortcomings.
Research on the Long-Term Sustainability of a Transition Towards Private Electric Vehicles
Authors: Gao Yujia
Published: June 2023

In recent years, a conflict has arisen between the urgency of fixing climate change and the reliance on cars as the primary mode of transportation. Electric vehicles have the potential to satisfy both conditions. With the accelerating growth in the EV market, it would seem as if they will soon become the future of transportation. Before a complete transition is made to EVs, it is necessary to assess the true sustainability of an EV. Due to the massive scale of the change in transportation, consequences for mistakes are significantly amplified. This paper sets out to research and evaluate EVs' sustainability compared to fossil-fule vehicles. Contrary to popular belief, EVs are nowhere near as beneficial to the environment as people had hoped. First, the concept of privately owned vehicles is unsustainable. In addition, EVs may emit more pollution than the fossil-fule vehicle. The exploitation of rare earth minerals is also causing heavy environmental damage while involving child labor. Despite this, if the issues are recognized and acted upon, it is reasonable to believe EVs still have the potential to act as a stepping stone to sustainable transportation for all.

This study introduces sources and impacts of marine debris, analyses distribution and effects with an example of the Great Pacific Ocean Garbage Patch by studying the direction of ocean current and using QGIS technology, and provides some control measures. Results show that plastic is the predominant constituent of marine debris. Sources of marine debris include land-based and ocean-based. Marine debris has great impacts on creatures and people living in the sea and remote areas. Ocean currents are the main reason for the formation of the Great Pacific Garbage Patch, which is the movement of seawater driven by force acting on it. The temperature and salinity of seawater, and the trade and prevailing wind are long-term factors affecting the distribution of ocean currents, and the tropical cyclones are short-term factors. It suggests that the government should salvage and recycle marine debris, establish legislative regulations, incinerate it for power generation, and construct artificial islands. For personal, they should use reusable products, recycle reasonably, reduce energy use and avoid products that contain microbeads and microfibers.

People's demand for lighting and display is gradually increasing as society and technology progress. Therefore, the scientific community has been eager to find a new kind of luminescent material suitable for industrial society. The effort paid off, as scientists discovered light conversion and its efficient Organic Light Emitting Diode materials through experiments. These materials can be divided into three distinct generations as a result of continuous updating and iteration: the first-gen (first generation) of fluorescent materials, the second- gen of phosphorescent materials, and the third-gen of TADF. In order to let the public better understand the development history of OLED materials, this paper will focus on the mechanism of different materials to discuss the schemes and introduce some of the latest applications of these materials. At the end of this review, it will illustrate why TADF the third generation of OLED light emitting material is the most promising in terms of practical applications compared with other materials and the vision of the future of OLED.

The most frequent cause of chronic liver disease globally is non-alcoholic fatty liver disease (NAFLD). Potential risk factors for NAFLD have not received enough attention in Pakistan even though NAFLD has received substantial research. Objective: To assess risk factors for Non-alcoholic fatty liver disease. This study was conducted at the Department of Medicine Liaquat University, Hospital Jamshoro from 7th September 2020 to 6th March 2021. Methods: This research was cross-sectional. The study recruited a total of 195 patients via nonprobability sequential sampling. The ultrasound of all the patients was done by a sonologist for detecting NAFLD. Results: The stratification of NAFLD according to smoking, hypertension, obesity, hyperlipidaemia, uncontrolled diabetes mellitus, vitamin D deficiency was done. The statistical significance was observed for NAFLD in accordance with smoking, (p=0.00), hypertension (p=0.04), obesity (p=0.04), hyperlipidaemia (p=0.03), uncontrolled diabetes mellitus (p=0.04), vitamin D deficiency (p=0.04). Conclusions: This study has shown that the percentage of NAFLD was highest in age group (40-49 years). Males were more affected as compared to females. Smokers, hypertensives, hyperlipidemics and diabetics were more prone to develop NAFLD.
