Published: May 2021

The turbofan engine is one of the most critical aircraft components. Its failure may introduce unwanted downtime, expensive repair, and affect safety performance. Therefore, It is essential to accurately detect upcoming failures by predicting the future behavior health state of turbofan engines as well as its Remaining Useful Life. The use of deep learning techniques to estimate Remaining Useful Life has seen a growing interest over the last decade. However, hybrid deep learning methods have not been sufficiently explored yet by researchers.In this paper, we proposed two-hybrid methods combining Convolutional Auto-encoder (CAE), Bi-directional Gated Recurrent Unit (BDGRU), Bi-directional Long-Short Term Memory (BDLSTM), and Convolutional Neural Network (CNN) to enhance the RUL estimation. The results indicate that the hybrid methods exhibit the most reliable RUL prediction accuracy and significantly outperform the most robust predictions in the literature.

Authors: Suhail S. , Dwivedi J. , Mithal S. , Gupta R.C. , Gupta A. , Singh L.K.
Published: May 2021

BACKGROUND:Ptosis is derived from the greek word for falling and is the medical terminology describing a drooping
or abnormal lowering of an anatomical area. Ptosis that obstruct the pupil may interfere with the normal development of
vision, resulting in amblyopia in children2 .In adult it may impair the field of vision and interfere with activities of daily
living Ptosis is broadly classified into congenital and acquired,based on age of onset of the ptosis.Ptosis that is present at
birth or within the first year of life is called congenital ptosis. Ptosis that presents after the age of one year is termed
acquired ptosis. The treatment of ptosis depends upon the underlaying etiology. Ptosis usually does not improve over
time and nearly always require corrective surgery. Depending upon the severity of congenital ptosis ,patients should be
monitored every 3-12 months for sign of amblyopia due to congenital ptosis. In mild cases of congenital ptosis
observation is sufficient ,if no sign of amblyopia, strabismus and abnormal head posture are present. METHODS:This
study was conducted in the Upgraded Department of Ophthalmology,LLRM Medical College,Meerut during 2018–2019.
Study design-A Population based Prospective interventional study was done on patients selected from OPD and camps
during 2018-2019. Plan & Work: All patients with ptosis who are attending ophthalmology OPD and admitted in eye
wards were included in the study provided they fulfill the inclusion criteria. RESULTS AND CONCLUSION: The
subjects in our study were more males 12(66.66%) than females(33.33%). In our study there were 12(66.66%) patients of
myogenic ptosis,out of them 11(61.11%) had frontalis sling surgery and 1(5.55%) had levator resection surgery. There
was 2(11.11%) cases of neurogenic ptosis which was congenital in nature and in which 1(5.55%) is operated with
frontalis sling &1(5.55%) with levator resection surgery. Most commonly performed surgery was frontalis sling
14(77.77%) followed by levator resection 2(11.11%) and 2(11.11%).

Published: May 2021

Malaria is a serious public health burden in Senegal. Accurate diagnosis is essential to avoided
unnecessary presumptive treatment. Malaria diagnosis currently relies on identifying malaria parasite
using microscopy and detecting soluble parasite antigens by Rapid Diagnostic Tests (RDT). These techniques do not detect
low-level, sub-patent malaria infections and are inherently hazardous and invasive. To overcome these obstacles, alternatives
diagnostics method were explored. In contrast to blood, saliva presents a reduced biohazard and can be painlessly collected
in relatively large quantities by individuals with moderate training. The objective of this study was to use saliva collected in
OmnIGEN Kits as an alternative sample for malaria detection. Methods: A total of 77 febril patients tested malaria positive by
mRDT were enrolled in this study. From each patient, blood sample was collected for dried blood spot and blood smear; and
saliva sample on OMNIGEN kit. Parasite density was determined from smear and Plasmodium falciparum DNA was extracted
from both dried blood spot and saliva samples collected from the same patients. Extracted DNA was amplied by qPCR
machine. Results: Malaria prevalence using qPCR was 98,7% and 60% respectively with blood and saliva. Compared to blood,
saliva showed a sensitivity; specicity; positive predictive value of 60%; 100 %; and 100 %. The concordance between parasites
detection from saliva and blood was (p = 0.45). In addition, no difference was found between these two methods and the
microscopy counting. Conclusions:Saliva could be a non-invasive alternative method for P. falciparum detection and
epidemiological surveillance in country with limited ressources.
AN UNSUSUAL CASE OF ISOLATED EXTRAOCULAR MYOCYSTICERCOSIS: MASQUERADING AS A SUPERIOR RECTUS MUSCLE ABSCESS

Published: May 2021

Human cysticercosis is caused by the larval form of the swine tapeworm Taenia solium.It can affect the central nervous
system, the eye, skeletal muscles and subcutaneous tissues. In the orbit, cysticercosis can lodge into any extraocular
muscle or other adnexal structures and are usually found as part of a generalized systemic infestation and very rarely
seen with isolated infestation of a single extraocular muscle.Hence, sometimes as it was in our case,it is very difficult to
differentiate an isolated extraocular muscle cysticercosis from extraocular muscle abscess or lymphoma. So,we, at our
institute report a rare and unusual case of isolated right superior rectus muscle cysticercosis which presented with ptosis
and painless swelling of the right upper eyelid, which was in fact discovered later masquerading as a superior rectus
abscess.
Developing a Data-Driven Unsupervised Pattern Recognition Approach for Sensor Signal Anomaly Detection
Authors: Iranmehr Ensieh , Ferreira Ricardo , Bohnert Tim , Freitas Paulo
Published: May 2021

Coming up with a system for early detection of machine damages and failures is one of the important challenges in the industrial maintenance procedure to avoid additional costs and downtimes. To approach this goal, this paper uses the signal gathered by a sensing system which employed a spintropic sensor to measure the magnetic field around the machine which somehow shows the machine's behaviour. Using this signal and focusing on analysing and processing the signal, this paper develops a data-driven method to recognize signal patterns and subsequently detects anomalies. A challenging task that we succeeded to overcome in this paper is recognizing relevant signal patterns without having any prior knowledge. An algorithm designed for this task is therefore completely unsupervised which makes it consistent and suitable to apply it for the signals gathered for other types of machines. Using both frequency and time domain information, the proposed algorithm, which utilizes signal processing and machine learning techniques, is able to efficiently identify relevant signal patterns. Clustering results on the real data gathered by the aforementioned sensor have shown the high accuracy of 99.38% in recognizing patterns. Furthermore, an anomaly score measure is used and according to its distribution, anomalies are detected appropriately.

Kondisi ini menyebabkan gerakan ekstremitas atas berulang yang diperlukan oleh penggunaan perangkat media komunikasi darling sehingga kontraksi otot secara terus menerus di leher dan bahu, yang dapat menimbulkan kerentanan terhadap gangguan muskuloskeletal akibat kerusakan mikroskopis pada otot, saraf, dan pembuluh darah selama menjalankan perannya.
Pemahaman Sabda Pengampunan Allah Dalam Sakramen Tobat Menurut Karl Rahner
Authors: Martasudjita E. Pranawa Dhatu
Published: May 2021

Abstrak: Dari pengamatan, tidak banyak tulisan teologis tentang sakramen tobat atau sakramen rekonsiliasi di lingkungan bahasa Indonesia selama ini. Begitu pula, ada kesan bahwa pemahaman umat Katolik mengenai sakramen tobat cukup terbatas. Dari sinilah artikel ini ingin memberi sumbangan pemikiran teologis melalui kekayaan dan kedalaman pandangan teologis Karl Rahner mengenai sakramen tobat. Dari penelitian penulis, sabda pengampunan Allah menjadi inti pemikiran Rahner tentang sakramen tobat. Dengan metode teologi transendental sebagaimana dikembangkan oleh Karl Rahner, penulis mengupas secara kritis pemahaman sabda pengampunan Allah melalui alur pemikiran sakramental Rahner. Rahner berpendapat bahwa  manusia  memiliki  pengalaman  dasar  akan  dosa-kesalahan yang tak dapat dihapus oleh diri sendiri, dan justru karena itulah manusia senantiasa mendambakan sabda pengampunan Allah sebagai pemberian diri Allah (Selbstmitteilung Gottes) yang berpuncak pada wafat dan kebangkitan Kristus. Melalui Gereja, sabda pengampunan Allah itu dihadirkan melalui aneka macam bentuk, sedangkan yang khusus dan istimewa melalui sakramen tobat. Tulisan ini ditutup dengan penyampaian poin-poin relevansi pandangan Rahner tersebut bagi Gereja sekarang ini.

Kata-kata kunci: Sabda pengampunan Allah, sakramen tobat, sakramen  rekonsiliasi,  teologi  sakramental,  teologi  transendental, belas kasih Allah.

 

Abstract:  Theology  of  Sacrament  of  reconciliation  has  not  been widely written and developed in Indonesia, and therefore the general understanding among the faithful. This article is to contribute, particularly by presenting Karl Rahner’s theology on the sacrament of reconciliation. Rahner focused on the forgiving word of God. Employing his transcendental method, this article is presenting a critical study on the understanding of Rahner’s forgiving word of God as well as his sacramental theology. Rahner showed that human beings themselves aware and know of their experience of sin or guilt and could not just get out of it, and because of that human beings themselves are longing for forgiveness and God’s forgiving word (Selbstmitteilung Gottes) revealed per exellentiam in the death and resurrection of Christ. Disciples of Christ gathered as people of God or church make present God’s forgiving word here and now in various forms, yet especially in the sacrament of reconciliation. The article shall conclude with points of relevance for the church today.

Keywords: God’s forgiving word, sacrament of penance, sacrament of reconciliation, sacramental theology, transcendental theology, mercy of God.

A Tuberculose (TB) é uma doença infecto-contagiosa que tem como agente etiológico o Mycobacterium tuberculosis. Esta é considerada um problema de saúde pública global, visto que é uma das principais causas de morte no mundo. Pode acometer qualquer indivíduo; no entanto, há aqueles mais vulneráveis que podem ser acometidos, como soropositivos para o Virus da Imunodeficiência Humana (HIV) e profissionais da área da saúde. A coinfecção TB-HIV causa impactos no comportamento da epidemia de ambas as doenças, sendo também responsável pelo aumento dos índices de mortalidade, tornando-se um desafio para a saúde pública. Este trabalho teve como objetivo analisar os casos de coinfecção tuberculose e HIV no Estado de Goiás, no período de 2008 a 2019. Foi realizado um estudo observacional descritivo, a partir dos dados disponibilizados no SINAN (Sistema de Informação de Agravos de Notificação). Os resultados obtidos mostram que de 2008 a 2019, foram notificados 13.347 casos de tuberculose em Goiás. Destes, a taxa de coinfecção TB-HIV foi de 0,20% (27 casos). Houve uma maior frequência de casos em indivíduos do sexo masculino (81,5%) e faixa etária de 20 a 39 anos (51,8%). A partir deste estudo foi possível notar a importância do diagnóstico clínico e laboratorial da TB, para tratamento correto e precoce desta doença e para a eliminação da micobactéria, responsável pelo aumento da replicação do HIV. Também detectou-se a necessidade de que novos estudos sejam realizados, para possibilitar traçar o perfil desta coinfecção.

Interlok from a Multiculturalism Perspective
Authors: Syed Othman Syed Mohd Zakir
Published: May 2021

Interlok may be read as a multiculturalism narrative that depicts the process of building a national identity, which develops from a rigid ethnic identity. Through the narrative of social events, an envisioning of a gradual formation of a national identity, situated within a multicultural space is presented by the author. This vision of multiculturalism is perhaps an ideal, but it reflects the author’s optimism for a future where a nation can be formed from the unity of its multicultural diversity. This ideal form of multiculturalism goes beyond assimilation as it is indeed a kind of integration that emphasizes on the culture of the majority as the dominant culture. The practice of this dominant culture must be just and equal as it evolves into the ideal national culture. However, this vision may have its detractors. It may give rise to a false identity that differs from the social identity of the real world. Nevertheless, this paper argues that the author’s vision for the formation of the ideal national identity in Malaysia’s multicultural society is one that is visionary and forward-looking showcasing his effort in promoting positive values in society through literature.

A qualidade de sementes de soja produzidas pode ser alterada em função da posição em que a vagem é produzida na planta. Desta forma, o presente trabalho tem por objetivo avaliar a qualidade fisiológica de sementes de soja produzidas em diferentes estratos da planta (inferior, mediano e superior), e mais o tratamento testemunha (colheita de todas as sementes produzidas na planta), logo após a colheita, aos 170 e 350 dias de armazenamento das sementes. O delineamento experimental foi em delineamento de blocos casualizados, sendo os tratamentos arranjados em esquema fatorial duplo, correspondendo a 4x3 (quatro estratos da planta e três épocas de avaliação). Para realização da pesquisa foi utilizada a cultivar de soja NS 6209, com hábito de crescimento indeterminado. As sementes foram avaliadas quanto a determinação do teor de água e massa de 1.000 sementes e pelos testes de germinação e envelhecimento acelerado. De acordo com os resultados obtidos conclui-se que o estrato de produção não influenciou a qualidade das sementes produzidas para os testes de germinação e envelhecimento acelerado. Porém a massa de mil sementes é superior para as sementes produzidas no estrato superior e mediano. O armazenamento de sementes de soja por 350 dias afetou o porcentual de germinação e vigor das sementes de forma negativa, independentemente do estrato de produção das sementes.

Published: May 2021

In this paper, the behavior of the oil price series named OIL is examined. The non-stationarity on average and variance, with the non-normality of the OIL series distribution, indicate the volatility of the series. The study is based on a combination of the Box-Jenkins methodology with the GARCH processes (Engle and Bollerslev). The first part models the lnOIL series in which, by applying the first difference the series becomes DlnOIL. Then the Box-Jenkins methodology is applied. The choice of the model was made on basis of minimization of criterion -Akaike (AIC), Shwarz (SIC)- and maximization of log likelihood (LL). Of the four models identified, ARMA (3.1) is retained. According to the statistical indicators of the ARMA model (3,1), the nature of the residuals and other tests, it is shown that the series of squares of the residuals follows a conditionally heteroscedastic ARCH model. The second part is devoted to a symmetrical and asymmetrical GARCH modelling. The model used for predicting volatility is the EGARCH model (1,2). The data available relates to 3652 daily values of the change in OIL, from 01/01/2019 to 12/31/2019. The forecast is made for the first three months of 2020; the result concludes that the predicted values and the current values are very close, and that the model ARIMA (3,1,1) + EGARCH (1,2) is the best forecast model.
Chinese Science Fiction in the Anthropocene
Authors: Imbach Jessica
Published: May 2021

A green future has become a central promise of the Chinese state and the environment is playing  an increasingly important role in China’s bid to promote itself as a political alternative to the West. However,  Chinese state environmentalism and its promotion of “ecological civilization” (shengtai wenming  ? ??? )  have so far proven more aligned with political interests rather than environmental goals. At the same time,  low -orbit  industrialization  as  a  response  to  the  climate  change  or  the  resurgent  fantasy  of  p opulation  control  as  a  necessity  from  the  standpoint  of  biology  in  environmentalist  discourse  are  increasingly   entangled with anxieties and speculations about Chinese visions of the future. Using Liu Cixin’s short story  The Sun of China  ( Zhongguo  taiyang ???? , 2001) and the 2019 blockbuster science fiction movie  The  Wandering Earth  ( Liulang diqiu ???? ) by Frant Gwo as its point of departure, this paper discusses how  current narratives of the Anthropocene are reflected and negotiated in Chinese science fiction. While both works demonstrate the symbolic and economic importance of science and technology to China’s growth and  self-image, they also reveal that we cannot separate questions of the planetary from the historical contexts, in which they emerge.
Ornithological Passions of American Poet Celia Thaxter
Authors: Taylor Ellen
Published: May 2021

American poet Celia Leighton Thaxter (1835 – 1894) was shaped by both environmental beauty and destruction she witnessed in her New England community. As a woman who spent much of her life on a small wind-swept island, she was educated by seasons and migrations that later informed her work. A brief education among Boston’s literary elite launched her creative career, where she focused on her local ecology. At that time, over-hunting and newly fashionable plumed hats and accessories had created a serious possibility of avian decimation. By creating awareness of humans’ culpability for birds’ endangerment, Thaxter’s work evoked public sympathy and contributed to social and political change.

      This essay applies ecofeminist and cultural analyses to Thaxter’s work written as part of the 19th century bird defense movement, by examining the emotional rhetoric employed and activism implied in her poems and prose about birds, specifically: “The Kittiwakes,” “The Wounded Curlew,” and “The Great Blue Heron: A Warning.”  Little attention has been paid to Thaxter’s didactic poems which use birds as subjects to instruct children and adults about the fragility of birdlife and to warn of humans’ destructive behaviors. These works illustrate Thaxter’s ecological sensibility and her use of emotion and reason to communicate an ecological message. Her poetry and prose about birdlife fortified the budding Audubon Society and contributed to the birth of the environmental movement. We can learn from such poetic activism, from attention to nature turned commodity, and the dangers of depleting finite resources. In our global environmental crisis, we recognize the interwoven relationships between birds and humans. Perhaps poems can help stymie our current ecological trajectory.

A backstepping, fluviatile-paralic-marine succession, Sinemurian, Lower Jurassic, Skåne, southern Sweden
Authors: Erlström M. , Sivhed U. , Surlyk F.
Published: May 2021

A temporal exposure of a Lower Sinemurian succession of fluviatile, coastal plain and marine sediments was accessible for study during a short time interval in 1997 at Örby, NW Skåne, Sweden. The succession adds significantly to the knowledge and understanding of the Sinemurian sedimentary evolution of the Fennoscandian Border Zone and the north-eastern margin of the Danish Basin. The top of the section overlaps the base of a section previously exposed at the nearby quarry at Gantofta. The combined evidence from Örby, Gantofta and a few borings shows that Sinemurian sedimentation took place during marked stepwise transgression. This is recorded by backstepping of the depositional environments from braided streams, over lakes and swamps, to estuarine and finally fully marine, offshore conditions. The sedimentary packages of the individual systems are well defined and separated mainly by sharp boundaries representing lacustrine, estuarine and marine flooding and ravinement surfaces. A regional sea-level rise punctuated by a minor fall is suggested to be the main factor controlling Early Jurassic basin evolution of the northeastern margin of the Danish Basin and the Fennoscandian Border Zone.

Published: May 2021

The results of a pilot study on late Arenigian ostracodes of Bornholm, Denmark,
are reported. The hard thermally altered limestone was disintegrated with sodium hyposulphite, the yielded ostracode material is of satisfactory preservation. The ten identified genera include palaeocopes (Glossomorphites, Aulacopsis, Ctenentoma, Asteusloffia, Euprimites), eridostracans (Conchoprimitia), cytherelliformes (Unisulcopleura) and metacopes (Elliptocyprites, Longiscula, Microcheilinella and “Silenis”). The studied ostracode assemblage shows resemblance to that of the Central Baltoscandian Confacies Belt.
Palaeodirectional and palaeointensity results of Paleocene and Eocene basalts from West Greenland
Authors: Riisager Janna , Perrin Mireille
Published: May 2021

Twelve sites (57 drill cores) from two lava series and one dike were sampled for a palaeomagnetic study of the late Paleocene and early Eocene West Greenland flood basalts. Most of the rocks exhibited well-defined one component remanent magnetization with high unblocking temperatures (mostly above 500°C) and high median destructive fields (30–40 mT). All the rocks are reversely magnetized and, when combined with 40Ar/39Ar ages (Storey et al. 1998), a direct correlation with the geomagnetic polarity time scale can be made.
Rock magnetic experiments indicate varying degree of both high temperature (deuteric) and low temperature (hydrothermal) oxidation of primary titanomagnetite. Twenty-three samples with high Curie point (~570°C) were chosen for Thellier palaeointensity experiments. Eleven of them, coming from three different cooling units, yielded reliable palaeointensity estimates. The results are reasonably coherent within sites, and the site-mean virtual dipole moments (VDM) are 1.8, 9.0 and 15.4×1022Am2 . The lowest VDM most probably corresponds to the ~94 ka long C24n.1r subchron, while the two other VDM’s close to present-day and higher than present-day values correspond to chrons C26r and C24r respectively.
A mid-Cambrian shelly fauna from Ritland, western Norway and its palaeogeographical implications
Authors: Bruton David L. , Harper David A.T.
Published: May 2021

A new mid-Cambrian shelly fauna from Ritland, western Norway, significantly extends the known development of the Andrarum limestone facies to the edge of the Baltic craton. The assemblage includes the trilobitesAxagnostus fallax (Linnarsson), Solenopleura bucculenta Grönwall, Anomocare cf. laeve (Angelin) and abundant, etched specimens of the linguliformean brachiopod Treptotreta? socialis (von Seebach) together withDictyonina ornatella (Linnarsson); the fauna indicates the presence of the Jincella brachymetopa Zone and also includes hyoliths, bradoriid crustaceans and sponge spicules. Elsewhere the trilobites and brachiopods have widespread distributions in amphicratonic settings during this part of the mid-Cambrian; the Scandinavian faunas signal the inshore migration of these more cosmopolitan elements, tracking the shallower-water development of calcareous facies of the Andrarum Limestone.
