Published: December 2021

In Indonesia, in 2014 the total number of pregnant women was 5,192,427, only 5,167 (0.1%) were tested for HIV. The HIV virus can be transmitted from HIV-infected mothers to their children during pregnancy, during labor and breastfeeding. HIV transmission from mother to child can actually be intervened with PMTCT. However, the coverage is still low at 8% in 2010. Basic level health services can be assisted by cadres in MCH services by motivating and supporting pregnant women by motivating pregnant women to test HIV / AIDS.

This study used a cross-sectional approach. The sample in this study was a Posyandu Cadre in Cileles Village. Sampling using total sampling technique with the number of samples that correspond to the inclusion and exclusion criteria as many as 53 respondents.

The research shows that the level of good knowledge is mostly in the age group of 20-35, the best knowledge is mostly at the junior high school level, and the best knowledge is mostly on cadres with a working period of 0-5 years.

Most respondents have sufficient knowledge about HIV / AIDS transmission from mother to child. Sufficient knowledge can be obtained from various sources, such as: mass media, books, and information obtained from health workers.

Authors: Dwi Tamara Metha
Published: December 2021

Indonesia is a country that still holds the principle of heterosexual relations even though many countries have legalized same-sex marriage. In West Java, there are many lesbian groups. Social institutions indicate that there are at least 185 lesbians in Bandung who are members of 14 small groups of 10-20 people. This research is a descriptive ethnographic study using qualitative data. To obtain qualitative data, researchers prioritize data collection techniques in the form of in-depth interviews, to dig deep information from informants. Family and environmental factors greatly influence an individual's sexual orientation. Conflicts that occur in the family that involve disappointment with the figure of a father coupled with disappointment with the opposite sex become an amplifier for individuals to change their sexual orientation into lesbians. The role of the family and surrounding environment that needs to be improved in paying attention to their children's relationships

Hubungan Kebiasaan Meminum Teh dan Kopi dengan Kejadian Anemia pada Ibu Hamil di BPM Bidan “E” Desa Ciwangi Kecamatan Balubur Limbangan Kabupaten Garut
Authors: Sri Iriani Oktarina , Ulfah Ulfah
Published: December 2021

Anemia adalah penurunan kapasitas darah dalam membawa oksigen karena jumlah sel darah merah yang kurang dari normal. Menurut World Health Organisation (WHO), 40% kematian ibu di negara berkembang berkaitan dengan anemia pada kehamilan dan kebanyakan anemia ini disebabkan oleh defisiensi besi. Anemia defisiensi besi adalah anemia yang terjadi akibat kekurangan zat besi dalam darah. Zat besi yang berasal dari makanan seperti daging, hati, telur, sayuran hijau dan buah- buahan diabsorpsi di usus halus. Penyerapan zat besi ini dipengaruhi oleh faktor adanya protein hewani dan vitamin C, sedangkan yang menghambat serapan adalah kopi, teh, garam kalsium dan magnesium karena bersifat mengikat zat besi, Di samping itu, dalam the dan kopi ada senyawa yang bernama tanin. Tanin ini dapat mengikat beberapa logam seperti zat besi, kalsium, dan aluminium, lalu membentuk ikatan kompleks secara kimiawi. Karena dalam posisi terikat terus, maka senyawa besi dan kalsium yang terdapat pada makanan sulit diserap tubuh sehingga menyebabkan penurunan zat besi (Fe). Tujuan penelitian ini untuk mengetahui Hubungan Kebiasaan Meminum Teh dan Kopi Dengan kejadian Anemia pada Ibu Hamil di BPM Ny. E Periode April-Juni 2018 Kabupaten Garut. Jenis penelitian kuantitatif dengan pendekatan Cross sectional. Jumlah sampel sebanyak 50 orang yang di ambil secara insidental sampling. Data yang digunakan yaitu data primer yang diambil secara langsung menggunakan lembar ceklis dan alat cek Hb Easy Touch. Analisa data berupa univariat dan bivariat dengan menggunakan uji chi- square. Hasil data 28 orang (56,0%) mengalami anemia dan 22 orang (44,0%) tidak anemia. Terdapat korelasi antara kebiasaan meminum teh dan kopi dan kasus anemia pada ibu hamil di BPM Ny. E chi square (24.219) > chi tabel (7,38) dan p value (0,000) < a (0,05). Penelitian ini menyarankan bagi ibu hamil agar menghindari meminum teh atau kopi secara langsung sebelum dan sesudah makan karena dapat menghambat penyerapan zat besi dalam darah.

Indigenous Fishing Methods of the Moyon Tribe of Manipur (India) and Myanmar
Authors: Moyon Wanglar Alphonsa , Chara Elija
Published: December 2021

Fishing is one of the main economic activities of the Moyon tribe living in Manipur (India), and Myanmar. For many centuries, Moyons used indigenous methods for fishing. However, in recent years, indiscriminate fishing using modern technologies has led to an ecological crisis which not only affected the ichthyofauna diversity but also affected the livelihood of individuals depending on fishing as well as the sustainability of the indigenous fishing methods. The paper explores the indigenous fishing techniques and practices of the Moyon tribe. The study adopted a qualitative-exploratory research method with ethnography as the primary component. Data were collected from on-site observations of fishing and discussions with the local Moyon population. The study revealed that indigenous fishing methods have become unsustainable due to misuse by the fishers. Another significant observation was the shift in fishing methods from traditional to modern (market) gears. The recently used fishing gears are a threat to the fish population, aquatic ecosystem, and indigenous knowledge of fishing crafts. The study concludes that unsustainable fishing by the Moyon tribe is connected with poverty and the lack of development and education.
Maputo Special Reserve and dung beetle conservation in the heterogeneous landscape of the Maputaland Centre of Endemism
Authors: Escobar Federico , Davis Adrian , Deschodt Christian M , Scholtz Clarke H
Published: December 2021

Background: Maputo Special Reserve (MSR) in Mozambique lays within the Maputaland Centre of Endemism (MCE) and protects the biota of a habitat mosaic dominated by coastal dune forest and inland sand forest patches of different sizes surrounded by natural grassland. Objectives: To determine the importance of woody versus grassland vegetation for supporting endemic east coast versus widespread savanna dung beetles in the MCE in the face of increased accessibility and exploitation of woody vegetation in southern Mozambique, especially by charcoal burners.Method: We used general linear mixed models, additive partitioning of diversity and ordination to analyse species abundance and occurrence across a mosaic of three major habitats in the MSR (grassland, sand and dune forest).Results: High compositional heterogeneity was found between habitat types and study sites so that beta diversity was mostly higher than alpha diversity. Three distinct scarabaeine dung beetle assemblages defined from ordination were largely centred on the three habitat types. Out of a total of 61 species, greater numbers were associated with grassland (38) than sand (17) and dune forest (6) although abundance was greater in both dune forest and grassland than in sand forest. Biogeographical classification indicated that >40% of the species are endemic to the east coast of southern Africa with the remainder centred in adjacent savanna. Endemic east coast species were well represented in both forest (15) and grassland (11). Savanna species were better represented in grassland (27) than forest (8). Proportions of grassland species and their abundance declined across increasing patch sizes of sand forest becoming lowest in dune forest.Conclusions: Conservation of endemic, east coast dung beetle species requires the preservation of both natural grassland and sizeable patches of forest in an undisturbed habitat mosaic. As the east coastal system is relatively small in extent with the MCE widely transformed in South Africa, the MSR is an important contributor to regional conservation of endemic species.
An Isolated White Dwarf with a 70 s Spin Period

Published: December 2021

We report the discovery of an isolated white dwarf with a spin period of 70 s. We obtained high-speed photometry of three ultramassive white dwarfs within 100 pc and discovered significant variability in one. SDSS J221141.80+113604.4 is a 1.27 M
⊙ (assuming a CO core) magnetic white dwarf that shows 2.9% brightness variations in the BG40 filter with a 70.32 ± 0.04 s period, becoming the fastest spinning isolated white dwarf currently known. A detailed model atmosphere analysis shows that it has a mixed hydrogen and helium atmosphere with a dipole field strength of B

d
= 15 MG. Given its large mass, fast rotation, strong magnetic field, unusual atmospheric composition, and relatively large tangential velocity for its cooling age, J2211+1136 displays all of the signatures of a double white dwarf merger remnant. Long-term monitoring of the spin evolution of J2211+1136 and other fast-spinning isolated white dwarfs opens a new discovery space for substellar and planetary mass companions around white dwarfs. In addition, the discovery of such fast rotators outside of the ZZ Ceti instability strip suggests that some should also exist within the strip. Hence, some of the monoperiodic variables found within the instability strip may be fast-spinning white dwarfs impersonating ZZ Ceti pulsators.
Deep-learning Reconstruction of Three-dimensional Galaxy Distributions with Intensity Mapping Observations
Authors: Moriwaki Kana , Yoshida Naoki
Published: December 2021

Line-intensity mapping is emerging as a novel method that can measure the collective intensity fluctuations of atomic/molecular line emission from distant galaxies. Several observational programs with various wavelengths are ongoing and planned, but there remains a critical problem of line confusion; emission lines originating from galaxies at different redshifts are confused at the same observed wavelength. We devise a generative adversarial network that extracts designated emission-line signals from noisy three-dimensional data. Our novel network architecture allows two input data, in which the same underlying large-scale structure is traced by two emission lines of H α and [Oiii], so that the network learns the relative contributions at each wavelength and is trained to decompose the respective signals. After being trained with a large number of realistic mock catalogs, the network is able to reconstruct the three-dimensional distribution of emission-line galaxies at z = 1.3−2.4. Bright galaxies are identified with a precision of 84%, and the cross correlation coefficients between the true and reconstructed intensity maps are as high as 0.8. Our deep-learning method can be readily applied to data from planned spaceborne and ground-based experiments.
Translating TDWG Controlled Vocabularies
Authors: Baskauf Steven J , Zermoglio Paula
Published: December 2021

Users may be more likely to understand and utilize standards if they are able to read labels and definitions of terms in their own languages. Increasing standards usage in non-English speaking parts of the world will be important for making biodiversity data from across the globe more uniformly available. For these reasons, it is important for Biodiversity Information Standards (TDWG) to make its standards widely available in as many languages as possible. Currently, TDWG has six ratified controlled vocabularies*1, 2, 3, 4, 5, 6 that were originally available only in English. As an outcome of this workshop, we have made term labels and definitions in those vocabularies available in the languages of translators who participated in its sessions. In the introduction, we reviewed the concept of vocabularies, explained the distinction between term labels and controlled value strings, and described how multilingual labels and definitions fit into the standards development process. The introduction was followed by working sessions in which individual translators or small groups working in a single language filled out Google Sheets with their translations. The resulting translations were compiled along with attribution information for the translators and made freely available in JavaScript Object Notation (JSON) and comma separated values (CSV) formats.*7

Colletotrichum has numerous host range and distribution. Its species are important plant pathogens, endophytes and saprobes. Colletotrichum can cause regular or irregular depressions and necrotic lesions in the epidermal tissues of plants. During this research Colletotrichum specimens were collected from Mengyin County, Shandong Province, China. A multi-locus phylogenetic analysis of ITS, GAPDH, CHS-1, ACT, TUB2, CAL and GS sequence data combined with morphology, revealed a new species and two known species, viz. C. mengyinense sp. nov., C. gloeosporioides and C. pandanicola, belonging to the C. gloeosporioides species complex. The new species is described and illustrated in this paper and compared with taxa in the C. gloeosporioides species complex.

The global loss of biodiversity is a pressing and urgent issue and halting loss is the focus of many international agreements and targets. However, data on species distribution, threats and protection are limited and sometimes lacking in many parts of the world. The British Virgin Islands (BVI), part of the Puerto Rican Bank Floristic Region in the Caribbean Biodiversity Hotspot, is rich in plant diversity and regional endemism. Despite the established network of National Parks in the BVI and decades of botanical data from international collaboration between the Royal Botanic Gardens, Kew and the National Parks Trust of the Virgin Islands, there was a need for consolidated data on species distribution across the archipelago and national lists for threatened and rare plants of conservation concern. The process of identifying the network of 18 Tropical Important Plant Areas (TIPAs) in the BVI, completed in 2018, delivered national lists and accurate data for all 35 Species of Conservation Concern. These data (3688 georeferenced records) are analysed here to reveal species distribution across the archipelago, within the TIPAs network and the National Parks System. The TIPAs network contained all 35 Species of Conservation Concern and 91% of all the records, as expected. Ten out of the 21 National Parks had one or more of the species present. Most species occur across the archipelago, while some are restricted range and/or endemics. These new data will help management of plant conservation efforts and resources in the BVI, contributing to the revision of the Protected Areas System Plan and local environmental policies and have relevance to the wider Caribbean Region.

Conservation translocation and reintroduction for the purpose of repopulating and reinforcing extirpated or depleted populations has been recognised as an important conservation tool, particularly for gibbon conservation in the immediate future. Feasibility assessments involving multiple factors, including taxonomic and genetic assessment of rescued and captive gibbons, are imperative prior to translocation and reintroduction programmes. In this study, we attempt to determine the subspecies and origin of captive Hylobates lar, White-handed gibbons, from Peninsular Malaysia to assist in future translocation and reintroduction programmes. A total of 12 captive and rescued H. lar samples were analysed using the control region segment of mitochondrial DNA. Sequence analyses and phylogenetic trees constructed using neighbour-joining, maximum likelihood, Bayesian inference, and network methods congruently differentiate all 12 captive individuals used in this study from other H. lar subspecies suggesting that these individuals belong to the H. lar lar subspecies. In addition, two populations of H. l. lar were observed: (1) a southern population consisting of all 12 individuals from Peninsular Malaysia, and (2) a possible northern population represented by three individuals (from previous studies), which might have originated from the region between the Isthmus of Kra, Surat Thani-Krabi depression, and Kangar-Pattani. Our findings suggest that the complete control region segment can be used to determine the subspecies and origin of captive H. lar.

Juvenile courts throughout Croatia impose sanctions on juvenile offenders (juveniles). Their decision-making often raises issues of their discretion in deciding on the application of juvenile sanctions, especially juvenile incarceration and its suspension (Reservation of the Right to Impose the Sentence of Juvenile Incarceration), which can be a significant issue in terms of the uniformity of the juvenile case law. Therefore, the research sought to examine whether there are certain formal criteria for distinguishing the application of juvenile incarceration from its suspension (Reservation of the Right to Impose the Sentence of Juvenile Incarceration), or if there are criteria that judges use when deciding when and in which cases to apply juvenile imprisonment, and when its suspension. Consequently, the following Hypothesis is set: There are criteria for distinguishing the application of juvenile incarceration from the suspension of sentence of juvenile incarceration (Reservation of the Right to Impose the Sentence of Juvenile Incarceration). Normative - descriptive, qualitative and descriptive analyses were used to test the hypothesis in the research.

In March 2020, the COVID-19 pandemic turned into an urgent priority for higher education institutions in that they had to move to remote teaching within a matter of weeks. This paper presents the results of a quantitative survey looking at the challenges university faculty were facing when moving their course(s) online during the first semester of the COVID-19 crisis.The survey looks specifically at course design and formats used in online teaching during the crisis and compares differences occurring between disciplines (STEM and management education). The outcomes overall mirror a sense of achievement due to the successful delivery of online courses with little preparation. Difficulties lecturers identified were related to promoting student interaction and engagement, technical issues, the effort required to plan and prepare online learning materials, and challenges with regard to online assessment. Having access to training and support in various forms was highlighted as an important success factor.
A Bayesian CNN-LSTM Model for Sentiment Analysis in Massive Open Online Courses MOOCs
Authors: Mrhar Khaoula , Benhiba Lamia , Bourekkache Samir , Abik Mounia
Published: December 2021

Massive Open Online Courses (MOOCs) are increasingly used by learn-ers to acquire knowledge and develop new skills. MOOCs provide a trove of data that can be leveraged to better assist learners, including behavioral data from built-in collaborative tools such as discussion boards and course wikis. Data tracing social interactions among learners are especially inter-esting as their analyses help improve MOOCs’ effectiveness. We particular-ly perform sentiment analysis on such data to predict learners at risk of dropping out, measure the success of the MOOC, and personalize the MOOC according to a learner’s behavior and detected emotions. In this pa-per, we propose a novel approach to sentiment analysis that combines the advantages of the deep learning architectures CNN and LSTM. To avoid highly uncertain predictions, we utilize a Bayesian neural network (BNN) model to quantify uncertainty within the sentiment analysis task. Our em-pirical results indicate that: 1) The Bayesian CNN-LSTM model provides interesting performance compared to other models (CNN-LSTM, CNN, LSTM) in terms of accuracy, precision, recall, and F1-Score; and 2) there is a high correlation between the sentiment in forum posts and the dropout rate in MOOCs.

In recent years, the role of internet and communication technology (ICT) has significantly impacted organisational activities including leadership practices. In this sense, interactions between leaders and followers have undergone tremendous technological changes that have reduced face-to-face interactions. Therefore, this study was designed to examine the imple-mentation of using technological advances to develop an e-leadership platform for teachers and school leaders. A survey of the feedback from 260 in-service teachers currently with two private secondary schools was undertaken. Findings revealed that the school principals had used ICT-based e-leadership practices to conduct online meetings with teachers and disseminate relevant information on the school’s administrative tasks. Most importantly, the principals have used e-leadership on a regular basis in planning and developing strategic school-improvement plans with teachers. As a result, the use of ICT-based e-learning has increased teachers’ efficiency and performance and contributed to practical and effective school administration.

Published: December 2021

Considering that application’s security is an important aspect, especially nowadays with the increase in technology and the number of fraudsters. It should be noted that determining the security of an application is a difficult task, especially since most fraudsters have become skilled and professional at manipulating people and stealing their sensitive data. Therefore, we pay attention to spot insecure apps by analyzing user feedback on Google Play platform using sentiment analysis. As it is known, user reviews reflect their experiments and experiences in addition to their feelings and satisfaction with the application. But unfortunately, not all of these reviews are real, fake reviews do not reflect the sincerity of feelings, so we have been keen in our work to filter the reviews and deliver accurate and correct results. This tool is useful for both users wanting to install an android app and for developers interested in app’s optimization.

DETERMINATION OF FIBER ORIENTATION IN HIGH ANGULAR RESOLUTION DIFFUSION IMAGING USING SPHERICAL HARMONICS AND PARTICLE SWARM OPTIMIZATION
Authors: Kamangar M. Hashemi , Mollaei M. R. Karami , Ghaderi Reza
Published: December 2021

The fiber directions in High Angular Resolution Diffusion Imaging (HARDI) with low fractional anisotropy or low Signal to Noise Ratio (SNR) cannot be estimated accurately. In this paper, the fiber directions are estimated using Particle Swarm Optimization and Spherical Deconvolution (PSO-SD). Fiber orientation is modeled as a Dirac delta function in [Formula: see text]. The Spherical Harmonic Coefficients (SHC) of the Dirac delta function in the [Formula: see text] direction are obtained using the rotational harmonic matrix and the SHC of the Dirac delta function in the [Formula: see text]-axis. The PSO-SD method is used to determine ([Formula: see text]). We generated noise-free synthetic data for isotropic regions (FA varied from 0.1 to 0.8) and synthetic data with two crossing fibers for anisotropic regions with SNRs of 20, 15, 10 and 5 (FA [Formula: see text] 0.78). In the noise-free signal (FA [Formula: see text] 0.3), the Success Ratio (SR) and Mean Difference Angle (MDA) of the PSO-SD method were 1∘ and 9.48∘, respectively. In the noisy signal (FA [Formula: see text] 0.78, SNR [Formula: see text] 10, crossing angle [Formula: see text] 40), the SR and MDA of PSO-SD (with [Formula: see text]) were 0.46∘ and 12.3∘, respectively. The PSO-SD method can estimate fiber directions in HARDI with low fractional anisotropy and low SNR. Moreover, it has a higher SR and lower MDA in comparison with those of the super-CSD method.

Authors: Popescu Cristina Raluca Gh.
Published: December 2021

The COVID-19 pandemic and the COVID-19 crisis have brought tremendous pressure on human beings and have raised deep concerns regarding the future of people's activities all over the world. The post-COVID-19 era presents a highly challenging perspective due to the uncertainties raised by the new environment, already weakened by the lack of cooperation among individuals, the ruthless competition between entities, and the fierce and aggressive decisions taken in haste, which affected the balance of our planet, the future of the next generations, and the well-being and mental health of people. Mindfulness represents a major solution to today's problems, offering individuals the possibility to become more focused, more connected with present situations, and more willing to understand not only their needs, but also the requirements of their colleagues, communities, and all that surrounds them. Mindfulness, as an investment in our lives, comes to support creativity, development, innovation, responsibility, sustainability, well-being, and a healthy and well-balanced business environment.

Authors: Vinusowndarya S. , Anuradha A.
Published: December 2021

Sustainable consumption practices help to reduce environmental impacts and fosters responsible consumers. Researchers have explored the positive drivers and negative barriers of fashion-conscious consumer (FCC) purchasing intention on fashion clothing. The study also examined the motives and outcomes of the phenomenon, such as rental landscape and frugality. Using the qualitative phenomenological method, researchers conducted 21 in-depth semi-structured interviews in India to tap into FCC's buying intention and experience. From the results of qualitative analysis, researchers identified “emotion” as a new parameter reflecting consumer passion and interpersonal relationships. Different themes emerged, such as selection of the style, attention-seeking, status value, cost factor (uncontrollable), and psychological value, which are the commonly identified motivators. Conceptual framework is developed to understand the perception towards green environment and sustainability. The implications are to improve the sustainable practices in the fashion sector through rental options and frugality.

Published: December 2021

The fragility of the global economy during the COVID-19 outbreak has shown the importance of supply chain sustainability. Although academic interest in the concept of sustainable supply chain management has risen significantly in the last decades, this concept has lately attracted the attention of policymakers as one of the dynamics of the “new normal” in the post-COVID-19 era.

Developing Self-Directed Learning Skills for Lifelong Learning
Authors: Hamlin Michael D.
Published: December 2021

This chapter seeks to provide guidance to learners on what may be for many a new perspective on learning that is different from learning styles developed in 13 years of K-12 education. Strategies such as rote memorization and other passive learning techniques may have been sufficient for K-12 classroom learning, but higher education, workplace, and online learning environments require more active and sophisticated learning strategies. It is the perspective of this chapter that the fundamentally different nature of post-K-12 learning and the constant acceleration of changes in knowledge will force learners to develop a more active and self-directed learning style.

Authors: Olayinka Olakunle , Win Thomas
Published: December 2021

The COVID-19 pandemic has brought to the fore a number of issues regarding digital technologies, including a heightened focus on cybersecurity and data privacy. This chapter examines two aspects of this phenomenon. First, as businesses explore creative approaches to operate in the “new normal,” the security implications of the deployment of new technologies are often not considered, especially in small businesses, which often possess limited IT knowledge and resources. Second, issues relating to security and data privacy in monitoring the pandemic are examined, and different privacy-preserving data-sharing techniques, including federated learning, secure multiparty computation, and blockchain-based techniques, are assessed. A new privacy-preserving data-sharing framework, which addresses current limitations of these techniques, is then put forward and discussed. The chapter concludes that although the worst of the pandemic may soon be over, issues regarding cybersecurity will be with us for far longer and require vigilant management and the development of creative solutions.

Authors: Felser Kerstin Christiane
Published: December 2021

For decades, the German automotive industry has benefitted from a process of IT-enabled transformation with the ongoing deployment of state-of-the-art IT. Despite the high relevance of IT for innovation and process efficiency, the industry has outsourced up to 80% of the IT budget to external IT providers as IT has generally not been seen as a core competence. In recent years, the phenomenon of digital transformation has emerged, along with the consequent disruptive impacts associated with digital technology deployment. One area of significance in the corporate environment is the current and potential impact of digital transformation on future IT sourcing strategies. Through an analysis of existing literature and a series of in-depth interviews with industry experts, the chapter examines how and why the German automotive industry is reviewing IT sourcing strategies in response to the anticipated implications of digital transformation. A change in the ratio between outsourcing and insourcing has a significant impact on in-house employment and third-party business operations.
Application of Optimization to Sizing Renewable Energy Systems and Energy Management in Microgrids
Authors: Dassa Khaled , Recioui Abdelmadjid
Published: December 2021

The smart grid is the aggregation of emerging technologies in both hardware and software along with practices to make the existing power grid more reliable and ultimately more beneficial to consumers. The smart grid concept is associated with the production of electricity from renewable energy sources (RES). For the distant isolated regions, microgrids (MG) with RES are offering a suitable solution for remote and isolated region electrification. The improper sizing would lead to huge investment cost which could have been avoided. The objective of this chapter is to review the state-of-the-art studies on the use of optimization techniques to renewable energy design and sizing. The chapter reviews the optimization techniques employed at different components of the microgrid including the energy sources, storage elements, and converters/inverters with their control systems.

Published: December 2021

The analysis and collection of data is an integral part of all research fields of the modern world. There is a need to perform forward mathematical modeling to improve the operations and calculations with modern technologies. Artificial neural network signifies the structure of the human brain. They can provide reasonable solutions quickly for the problems that classical programming cannot solve. An in-depth systematic study is presented in this chapter related to artificial neural network applications (ANN) for predicting the equilibrium conditions for gas hydrate formation, which can assist in designing future dissociation technology for gas hydrate so that this white gold can make world energy free for the future generation. This chapter can also help to develop a novel inhibitor for gas hydrate formation and save millions of dollars for the oil and gas industry.

Authors: Mishra Nishant , Prakash Punit , Gupta Anand Sagar , Dawar Jishnav , Kumar Alok , Mitra Santanu
Published: December 2021

Various improvements can be made to Darrieus vertical axis wind turbines (VAWT) for maximum performance in an urban environment. One such improvement is the inclusion of bio-inspired leading-edge tubercles to increase the aerodynamic performance. These structures, found on the flippers of humpback whales, are believed to aid the mammal in quick maneuvering. The objective of the chapter is to investigate and compare the performance of a Darrieus type VAWT with the inclusion of leading edge tubercles. The performance of the turbine with leading-edge tubercles on the blades is compared with the turbine with normal blade, computationally (with computational fluid dynamics using transition SST turbulence model) and experimentally. The focus lies on building an experimental setup to compare the performance of leading-edge tubercles with the baseline turbine.
Energy Resources and Their Consumption
Authors: Channi Harpreet Kaur
Published: December 2021

Power is a significant cause of economic growth and crucial to the sustainability of the economy. Energy consumption is an indicator of a nation's economic growth. Economic growth is focused, among other aspects, on the long-term acquisition of affordable, existing resources, and their use does not pollute the environment. Industrialization serves economic growth and consumes energy. In 2018, 68% of total capital power was consumed by largest energy-intensive areas. When fossil fuel is the primary source of energy, energy consumption is positively correlated with ecosystem cleanliness. Fossil fuels account for more than 70% of the decent energy expectations of India and other economies. In this chapter, problems related to non-renewable energy sources are discussed, and emphasis is given to use more renewable sources.

Published: December 2021

O artigo analisa eventos educativos ocorridos na América portuguesa setecentista, na capitania de Minas Gerais, inscritos nas práticas pedagógicas e civilizadoras do estado e da igreja em duas dimensões: na atuação das famílias quanto à construção de estratégias para a educação das crianças e jovens, por meio de seus capitais econômicos e culturais; nas ações pedagógicas para a conformação social da população mestiça, foco nas pretensões civilizadoras e de controle. As análises valem-se de fontes que, embora já bem conhecidas da historiografia colonial, são relativamente recentes no corpus documental das pesquisas sobre a história da educação no Brasil nos séculos XVIII e XIX: os testamentos, os inventários post mortem e os processos eclesiásticos.
COVID-19–Associated Pulmonary Aspergillosis in the Critical Care Setting
Authors: Livermore Jennifer M.
Published: December 2021

The first confirmed case of COVID-19 in the United States was reported on January 20, 2020. Most infected individuals experience a mild illness with loss of taste and smell, body aches, fatigue, cough, and fever. However, about 5% of patients become critically ill and experience more serious symptoms such as respiratory distress, pulmonary emboli, or even multisystem organ failure. Those who become critically ill with COVID-19 are at high risk for superinfections, including pulmonary, bloodstream, and urinary tract infections. Invasive aspergillosis is emerging as a serious secondary pulmonary infection in patients with COVID-19 who experience respiratory distress syndrome. If these patients are not accurately diagnosed and subsequently treated, the infection can be fatal. This case study describes COVID-19–associated pulmonary aspergillosis in the critically ill patient.
Analizy Space Syntax wobec zjawiska segregacji społecznej i izolacji przestrzennej obszarów mieszkaniowych
Authors: Olesiak Justyna
Published: December 2021

Space Syntax analysis in the Face of the Phenomenon of Social Segregation and Spatial Isolation of Residential Areas In many urban areas there is an observable extreme segregation of public space, in addition to the fact that many housing districts are spatially isolated from the city as a whole. As traditional methods of urban analysis provide poor guidelines in this context, an attempt to investigate this problem and present a different approach to segregation in urban design was made. This paper presents an investigation about how Space Syntax theories and methods can contribute to creating more detailed descriptions of spatial relationships in different districts and in the entire city. The research method employed was an analysis of the literature (both domestic and trade). Space-Syntax-based urban analysis enables demonstrating significant structural differences between districts and to determine the impact of urban forms on the spatial advantages of different areas of the city. It provides new opportunities to address segregation in urban design and formulate more effective anti-segregation interventions.
