Perante o uso desmedido dos recursos naturais surge uma corrida em busca de encontrar alternativas possíveis de recuperação desses ecossistemas. E este artigo traz uma revisão bibliográfica com o intuito de apontar alguns aspectos, que vêm sendo discutidos por pesquisadores no campo da biorremediação como técnica de reversão de contaminantes, bem como de apontamentos de ações futuras que podem vir a ser realizadas para minimizar os impactos ambientais. Entre os apontamentos realizados pelos diferentes autores consultados para este manuscrito, fica evidenciado que as técnicas de descontaminação são onerosas e algumas ainda apresentam subprodutos tóxicos em seus processos. Em alternativa a esta realidade se buscou, ao longo dos anos, meios para solucionar estes problemas, e a biorremediação ganhou espaço em detrimento de suas vantagens. De acordo com os autores das bibliografias consultadas, a biorremediação, além de utilizar seres vivos na tentativa de recuperar estes ambientes degradados apresenta custo baixo e vem ganhando, atualmente, difusão no Brasil. Todavia, alguns pesquisadores apontam, em seus estudos, que não basta haver uma corrente em busca de alternativas com estas características para remediar os ambientes impactados, é necessário haver consciência e políticas mais severas que se atentem para vir a garantir uma produção mais sustentável sem degradar o ambiente. Palavras-chave: Recursos Naturais. Políticas. Produção Sustentável. Ambientes impactados. Descontaminação AbstractIn the face of the excessive use of natural resources, a race is underway to find possible alternatives for the recovery of such  ecosystems. And this article brings a bibliographical review with the intention of pointing out some aspects that  have been discussed by researchers in the field of bioremediation as a technique for reversing contaminants as well as notes of future actions that can be carried out to minimize the environmental impacts. Among the notes made by the different authors consulted for this manuscript, it is evidenced that the decontamination techniques are costly and some still have toxic byproducts in their processes. As an alternative to this reality, over the years efforts have been made to solve these problems, and bioremediation has gained space to the detriment of its advantages. According to the authors of the consulted bibliographies, bioremediation, in addition to using living beings in an attempt to recover these degraded environments present a low cost and has been gaining, currently, diffusion in Brazil. However, some researchers point out in their studies that it is not enough to have a current in search of alternatives with these characteristics to remedy impacted environments, it is necessary to have awareness and more severe policies that are taken care to ensure a more sustainable production without degrading the environment. Keywords: Natural Resources.

Abstract Background Facial features and measurements are utilized to analyze patients’ faces for various reasons, including surgical planning, scientific communications, patient-surgeon communications, and post-surgery evaluations. Objectives There are numerous descriptions regarding these features and measurements scattered throughout the literature and we did not encounter a current compilation of these parameters in the medical literature. Methods A narrative literature review of the published medical literature for facial measurements used for facial analysis in rhinoplasty was done through the electronic databases MEDLINE/PubMed and Google Scholar, along with a citation search. Results A total of 61 facial features were identified. 45 points (25 bilateral, 20 unilateral), five lines (three bilateral, two unilateral), eight planes, and three areas. A total of 122 measurements were identified: 48 distances (6 bilateral, 42 unilateral), 57 angles (13 bilateral, 44 unilateral), and 17 ratios. Supplemental Figures were created to depict all features and measurements using either a frontal, lateral or basal view of the face. Conclusions This paper provides the most comprehensive and current compilation of facial measurements to date. We believe this compilation will guide further developments (methodologies and software tools) for analyzing nasal structures and assessing the objective outcomes of facial surgeries, in particular rhinoplasty. Moreover, it will improve the communication as a reference for facial measurements of facial surface anthropometry, in particular rhinoplasty.

Door Lock

Internet of Things is considerably increasing the levels of convenience at homes. The smart door lock is an entry product for smart homes. This work used Raspberry Pi, because of its low cost, as the main control board to apply face recognition technology to a door lock. The installation of the control sensing module with the GPIO expansion function of Raspberry Pi also improved the antitheft mechanism of the door lock. For ease of use, a mobile application (hereafter, app) was developed for users to upload their face images for processing. The app sends the images to Firebase and then the program downloads the images and captures the face as a training set. The face detection system was designed on the basis of machine learning and equipped with a Haar built-in OpenCV graphics recognition program. The system used four training methods: convolutional neural network, VGG-16, VGG-19, and ResNet50. After the training process, the program could recognize the user’s face to open the door lock. A prototype was constructed that could control the door lock and the antitheft system and stream real-time images from the camera to the app.

Vaccine Distribution

The spread of COVID-19 has been taken on pandemic magnitudes and has already spread over 200 countries in a few months. In this time of emergency of COVID-19, especially when there is still a need to follow the precautions and developed vaccines are not available to all the developing countries in the first phase of vaccine distribution, the virus is spreading rapidly through direct and indirect contacts. The World Health Organization (WHO) provides the standard recommendations on preventing the spread of COVID-19 and the importance of face masks for protection from the virus. The excessive use of manual disinfection systems has also become a source of infection. That is why this research aims to design and develop a low-cost, rapid, scalable, and effective virus spread control and screening system to minimize the chances and risk of spread of COVID-19. We proposed an IoT-based Smart Screening and Disinfection Walkthrough Gate (SSDWG) for all public places entrance. The SSDWG is designed to do rapid screening, including temperature measuring using a contact-free sensor and storing the record of the suspected individual for further control and monitoring. Our proposed IoT-based screening system also implemented real-time deep learning models for face mask detection and classification. This module classified individuals who wear the face mask properly, improperly, and without a face mask using VGG-16, MobileNetV2, Inception v3, ResNet-50, and CNN using a transfer learning approach. We achieved the highest accuracy of 99.81% while using VGG-16 and the second highest accuracy of 99.6% using MobileNetV2 in the mask detection and classification module. We also implemented classification to classify the types of face masks worn by the individuals, either N-95 or surgical masks. We also compared the results of our proposed system with state-of-the-art methods, and we highly suggested that our system could be used to prevent the spread of local transmission and reduce the chances of human carriers of COVID-19.

Willingness To Sacrifice

Do some people exhibit a greater willingness to sacrifice in romantic relationships and derive more satisfaction from doing so, even in the face of high costs? In a cross-sectional study and a daily experience study, we show that people low in interdependent self-construal were less willing to sacrifice when the costs were relatively high, whereas people high in interdependent self-construal were equally willing to make high- and low-cost sacrifices. Further, when people low in interdependent self-construal chose to sacrifice, they felt less authentic when the costs were high, which in turn, detracted from their satisfaction with sacrifice. In contrast, people high in interdependent self-construal did not feel less authentic and were buffered against feeling less satisfied when making more costly sacrifices. The findings identify a set of individuals who are more willing to sacrifice, even in the face of high costs, and who feel more satisfied and authentic when doing so.

La colonización dirigida, espontánea y estratégica, además de la permanente ampliación de la frontera agrícola para la extracción de recursos naturales, han determinado el uso y zonificación del espacio amazónico en los últimos 50 años. Las drásticas huellas socio-económicos, culturales y ambientales generadas por estos procesos han impactado negativamente la vida de los pueblos ancestrales y la naturaleza. Una consecuencia drástica es el cambio de la comprensión de la territorialidad en el interior de los territorios indígenas, y de la percepción que de aquel cambio tienen el Estado y los actores asentados en el entorno territorial comunitario. El presente estudio aborda el caso del pueblo waorani e inquiere cómo la ampliación de la frontera extractiva intensificaría los impactos negativos del proceso de desterritorialización en el Parque Nacional Yasuní, poniendo en mayor riesgo la integridad física y cultural de los de los pueblos que viven en aislamiento voluntario: Tagaeri y Oñamenane u otros de los cuales no se tiene referencia.   Abstract Targeted, spontaneous and strategic colonization, in addition to the permanent expansion of the agricultural frontier for the extraction of natural resources, has determined the use and zoning of the Amazonian space in the las 50 years. The drastic socioeconomic, cultural and environmental impacts generated by these processes have impated negatively the life of the ancestral peoples and nature. A drastic consequence is the change of the understanding of the territoriality in the interior of the indigenous territories, and the perception that the state and the actors settled in the community territorial environment have of that change. This study addresses the case of the Waorani people and inquires how the expansion of the extractive frontier would intensify the negative impacts of the process of decentralization in the Yasuní National Park, putting at greater risk the physical and cultural integrity of the peoples living in voluntary isolation: Tagaeri and Onamenane or others of which there is no reference.

ABSTRACT The potential size of India's dental market is vast and is expected to become one of the largest single country markets for overseas dental products and materials. The total market for the dental equipment and materials is estimated to be around US$ 90 million annually. There are more than 1, 80,000 dental professionals in India, 297 dental institutes and over 5,000 dental laboratories. Thus, there is a huge potential for the market of personal protective equipment (PPE) used for infection control in dentistry. India's market for dental products is extremely dynamic, with a current estimated growth rate of between 25 and 30%. Overall, the dental market is expected to grow by 20%.1 The personal protective equipment used in the practice of dentistry in India. Since dentistry is predominantly a surgical discipline, it leads to exposure to the pathogenic microorganisms harbored in blood, body fluids and other potentially infectious material. Thus, the use of adequate and good quality PPE is imperative for infection control in dental practice. With the growing potential of India's dental market, the growth of the market for PPE is inevitable. But, it is equally important to raise the awareness among dental community about good quality products adhering to required standards to prevent the usage of low-cost, uncertified and sub-standard products that decrease the safety levels of personnel. The present study is conducted with a view to observe the personal protective equipment used for infection control in dental practices.

A call for the integration of research experiences into all biology curricula has been a major goal for educational reform efforts nationally. Course-Based Undergraduate Research Experiences (CUREs) have been the predominant method of accomplishing this, but their associated costs and complex design can limit their wide adoption. In 2020, the COVID-19 pandemic forced programs to identify unique ways to still provide authentic research experiences while students were virtual. We report here a full guide for the successful implementation of a semester-long virtual CURE that uses Drosophila behavioral assays to explore the connection between pain and addiction with the use of a "lab-in-a-box" sent home to students. Individual components were piloted across three semesters and launched as a 100-level introductory course with 19 students. We found that this course increased science identity and successfully improved key research competencies as per the Undergraduate Research Student Self-Assessment (URSSA) survey. This course is ideal for flipped classrooms ranging from introductory biology to upper-level neuroscience courses and can be integrated directly into the lecture period without the need for building a new course. Given the low cost, recent comfort with virtual learning environments, and the current proliferation of flipped biology classrooms following the 2020 pandemic, this curriculum could serve as an ideal project-based active-learning tool for equitably increasing access to authentic research experiences.
